Study of diary products supply chain with its various components and Essay

Study of diary products supply chain with its various components and aspects - Essay Example We ensure that the amount of fat is reduced and this fat which has been removed is used in the making of products such as butter and cream, all these being the ingredients found in cheese, which will be our primary focus in this paper. Good manufacturing practices such as hygiene, quality assurance and marketing are critical (Andreas & Carl, 2011). Production requirements Cheese storage area capacity is predominantly determined by the target cheese types which are intended through put plans. The equipment which will be necessary for cheese making depends on the type of cheese being produced and facilities which are specifically designed are required, and advice/factory design should be sought. According to the nature and complexity of making cheese, which usually requires precision if one is considering going into cheese making, proper training is a basic requirement. The key areas for consideration in the manufacturing of cheese are pasteurization process of milk, quality control, h ygiene and finally marketing and distribution (Andrew, Dan, & Tom, 2006). Legal requirements There are stringent hygiene regulations to be adhered to since safety is an important consideration in the cheese business as is in any other food business. ... Cheese is a complex food comprising of only a few simple ingredients. There are thousands of varieties of cheese around the world developed by cheese makers, each with a unique taste, texture and nutritional profile. Absolutely, no cheese is similar and we have a large number of standards, due to the existing ways in adjusting the basic recipe of products such as mozzarella, Brie, blue, Swiss, Cheddar and many more. There are two basic types of cheese which we deal with and they are: Natural cheese which comprises of about four ingredients which are basic and they include salt and milk among others. The cheese nutrients such as calcium, protein and phosphorus are due to the milk being the main ingredient. Salt is required for the final transformation of liquid milk into cheese while also acting as a natural preservative. Processed cheese which is made from high-quality natural cheese. Therefore, it also comprises of the said nutrients (calcium, phosphorus and protein). One of its maj or differences with natural cheese is that processed cheese can be modified to have more calcium as well as extra vitamin D. For processed cheese, the processing is known to stop the aging process, thus maintaining its flavor, texture and smoothness over extended periods of time. Processed cheese can be customized for flavor and qualities such as a smooth melt responsible for making it versatile, tasty and easy-to-use food. There has to be careful application of amount of salt used since it will impact its firmness, flavor, food safety and preservation crucial for our customers. Supply Chain At the start of cheese supply chain, we have the farmers who supply the milk. There are well known unions who we deal with and have been in operation for well over a decade, who specialize in dairy

Performance Management Paper - Essay Example The self-assessment process allows the organization to discern clearly its strengths and areas in which improvements can be made and culminates in planned improvement actions that are monitored for progress" (Bohigas and Heaton, 2000). EFQM Excellence Model aims to select and award a confirmation of high quality health care provision to institutions or services which achieved excellence. To apply for the EFQM, a health care service provides data of activities derived from its self-assessment according to EFQM's nine award assessment criteria. These nine award assessment criteria are as follows: "leadership, people, policy and strategy, partnership and resources, processes, people results, customer results, society results, and key performance results" (http://www.proveandimprove.org/new/tools/index.php). The use of the Model could be facilitated in small groups and even possible for one individual. Good rapport among the stakeholders will ease the process as each will be involved in some ways with the Model. To be effective, management and organization heads needs to be actively involved. As the staff becomes familiar with the system of the model, self-assessment against the Model can be completed very quickly - within days for a very basic assessment. It can also be used as a "diagnostic tool" because areas for action are given emphasis. With tWith the models varying approaches: "questionnaire, matrix chart, workshop, pro-forma, and quality award simulation", an organization can set up their own assessment to fit specific structure of the organization. For emphasis, the following statements from http://www.proveandimprove.org/new/tools/index.php will be cited.

ExxonMobil and Rosneft Arctic Collaboration Essay

ExxonMobil and Rosneft Arctic Collaboration - Essay Example The entire project is at risk from a large number of factors that span the financial, compliance, strategic and operational domains. The project is set to create an open framework that allows information and expertise sharing along with data availability and accessibility. Another aim is to augment oil reserves and to ensure oil supply as per global demand. Similarly the project looks to develop world class expertise and to come to an agreement that is beneficial and protective throughout the life of the project. Another underlying aim for Exxon is to become a leading oil giant. A large challenge is to achieve cooperation across the table and to deal with a state controlled country. This may give rise to legal issues and the US Congress may be reluctant to support such an initiative. Environmental groups would also oppose efforts for exploration and the icy environment would be a large challenge to work with as well as problems in oil spills, waste disposal and oil transportation. Th e project would proceed as semi-sub drilling with daily costs of $700,000 producing some 160,000 barrels per day. A joint venture framework would be used as the political and economic climate of the US Russia relationship is precarious over the longer run. The largest risk anticipated by the project is price volatility in the international market given that the project stretches some two decades. The collaboration between Exxon Mobil and Rosneft Arctic Corporation is a very positive step in order to promote collaboration between the US and Russia. Moreover such collaboration can provide much required relief to the international energy markets as more oil is discovered and exploited. The Russian side has the territorial space and the jurisdiction while the American side has the capability to provide the technical expertise that is much required to carry out this project. The largest technical challenge will stem from the function of the TLP’s tendons under the

Discuss what criteria a decision maker will follow in a sustainable Essay

Discuss what criteria a decision maker will follow in a sustainable management plan - Essay Example Evidently, this is highly complex, and thus, the decision-making cannot rely on intuition of managers. This calls for a thorough assessment of impacts before resorting to a given decision. As a result, decision-making in sustainable management plan requires a structured process to aid in evaluating and assessing environmental impact, ethical and social issues to make a decision that serves the interest of all stakeholders involved. Multi-Attribute Decision Analysis is one of the structured processes that managers can use for making decisions in sustainability issues. This applies in a situation whereby a manager faces problems with competing decision criteria, for example, a decision between installation of a solar panel and plan for energy efficiency enhancement. Using Multi-Attribute Decision Analysis (MADA), such a decision takes four steps. The first step involves identifying the goals and decisions that the decision maker aims at achieving and framing of the decision (Hahn, Seaman and Rob 2). The second step is identifying the alternatives regarding the decision, as well as related attributes that contribute to the objectives of the decision. Third is specifying preferences for each individual attributes, as well as between attributes in agenda. Finally, the last step involves ranking alternative decisions basing on the attribute data, according to specified preferences. Similarly, another tool that managers can utilize for making sustainable management decisions is the Rational-Iterative Decision-Making Process. This process entails several elements that need to be evaluated in order to come up with a rational decision (Decision Making Methods and Tools: Choosing among alternative courses of action 3). This includes identifying the roles of individuals involved in the process such as forest managers, decision makers, and stakeholders among others. Additionally, it involves scoping the target area, determining the goals, creating measurable criteria for

In the second instance Fred was not able to understand why the meeting he had with a Japanese client did not progress despite his best efforts (from American point of view). The problems were not confined to his professional life only, his family specifically his wife was not comfortable in the new society as she had got tired of having no neighbors to talk to, being stared by people on the road, facing difficulty locating places and finding difficult to purchase the items of interest ( Black, p. 4). The problems were actually caused by their lack of understanding of the Japanese culture. Bailey Fred and his wife had very little time to prepare themselves for the cultural differences that were coming their way. Fred bei ng high on assertiveness (Javidan and House 2001, p. 289-305) , individualism, and low on power distance (Hofstede Models ) could not understand that Japanese values are different from American values and thus the business conduct in Japan had to be different that in America.

Experiences of divorced women versus divorced men Research Paper

Experiences of divorced women versus divorced men - Research Paper Example Because gender differences are constructed and reflected in daily interaction, the experience of marriage is quite different for men and women. The same is likely to be true of divorce.† (Amato, 2004, p.207) It then becomes interesting to look at how divorce affects the two genders. The following passages will argue that despite conventional notions about divorce being more traumatic for women than men, in reality both genders have an equally tough time of it, albeit in different areas. Firstly, statistics released by U.S. Census Bureau shows that while divorce rates hovered around the 2 percent mark during the 1980s, it has shot up to more than 15 percent currently. One should remember that this statistic excludes those people who remarried again. So, if divorce were to be counted even if the current marital status has changed, then a mind-boggling 60 percent of American adults have gone through this painful event in their lives. But since in advanced societies women tend to b e economically independent, they are better able to handle the period post divorce than women in the rest of the world. That women are able to handle the crisis is not to say that their standard of living does not fall. Statistics point out that the responsibility of rearing children can sap away financial resources of the woman, although the ones getting regular alimony stand a better chance of sailing through the crisis. Also, compared to recently divorced men, recently divorced women have less labor force experience, putting them at a disadvantage in availing of job opportunities. (Amato, 2004, p.207) Public support for divorced mothers are also limited, at best offering modest help for a short period of time. As a result of this condition, most divorced women think that the only sustainable solution to their problems is through remarriage, which they usually do within a few years of divorce. Of course, in the case of men, there is no noticeable decrease in their standards of liv ing post divorce. Social adjustment is another area where the genders fare differently. Social acceptance of divorce is gaining ground steadily and today there is less stigma attached to the idea of divorce. But at the same time, in the period following a divorce both men and women are experiencing decreased social support and companionship. This is particularly true if they have custody of children. It is also learnt that there are common problems faced by both divorced men and women: â€Å"Between employment, household management, and child care, single parents have little time left over for establishing and maintaining social networks. Also, divorced people often find that they have less in common with married friends. In addition, whereas married people can draw on the spouse's family for assistance and companionship, divorced individuals typically find that former in-laws withdraw over time. Furthermore, divorced people have a high level of residential mobility which tends to disrupt relationships with neighbors, friends, and community organizations. Overall, divorced and separated individuals report smaller social networks and less social support than do married individuals.† (Amato, 2004, p.208) There is also the important aspect of psychological adjustment post divorce. Divorce can be an emotionally upheaving event and can entail acute emotional distress. Older studies have shown that women are more psychologically affected compared to men,

Non profit organizations Article Example | Topics and Well Written Essays - 1000 words

Non profit organizations - Article Example The main priority which is laid while performing the broad duties mostly reflects upon determining the interests of the law. Also, the duties that perform by high rank officers are framed in such a way that demonstrates legal forms of working behavior. However, the main concern in such type of organization is to generate a balanced working atmosphere. This particular aspect is developed through executing various principles related to corporate governance in non-profit organizations. The best feature about this sort of organization is that all the officers along with other employees perform their respective assigned tasks quite effectively. Also, the duties of officers in a non-profit organization are determined through following a broader framework which considers the basic objectives of such type of organizations. This way, the broad duties along with the responsibilities of all the members including the officers get prioritized in a formative manner (Twaits, 1998). This paper will broadly consider the major aspects pertaining to the broad duties of officers along with employees in non-profit organizations. In addition, the aspects will be critically analyzed, backed up with a proper review and a personal reflection of the concerned article. Review of the Item As per the studies undertaken by Andrew Twaits (1998), numerous researches and surveys have been conducted upon managing the non-profit organizations (NPOs) belonging to this modern day context. With increased level of globalization along with internationalization, NPOs have been viewed to support the community members in terms of serving their best interests effectively. It has been learned that NGOs can very well move in aligning with the needs of the society by a certain degree. With due analysis, it can be stated that the different activities of NPOs have been able to widen the expectation levels of shareholders in terms of fulfilling their respective desires. The management along with the operationa l activities that takes place in a NPO and the duties perform by the officers as well as the employees is often recognized to be quite broad. It can be apparently observed that the different tasks and the duties that are performed by the officers along with the employees deliver a high range of performance within the organizations. According to the article, it can be viewed that there exist two sorts of organization that mainly comprise ‘unincorporated association’ and ‘incorporated association’. These associations eventually lead towards governing along leading NPOs to attain their predetermined targets. In this regard, the term ‘unincorporated association’ signifies the meaning of a chamber, club, federation, society, council, league, institute, union or guild, which is fundamentally voluntary in nature. This form of association is viewed to serve the basic purpose or serving the interests of a group of people. The other form of association i .e. ‘incorporated association’ is regarded as a form of association which can be understood as a legal entity that possesses a perpetual succession and also a common seal. This form of association is considered to be highly recognizable in nature. This particular association is formed with the intent of considering all the legal attributes that are needed to be fulfilled while forming an ‘incorporated association’. Strong approval from the government is required for the formation of such

Guillermo Financial Analysis Essay Example for Free

Guillermo Financial Analysis Essay Making a sound financial decision is a vital component of the success of a business. The business must conduct market research, description of products, services and marketing strategies, and setting principles for the business’s success. Expenses should be noted prior to writing a financial plan. The goal of a business is to operate on a predefined budget. Ensure there are no undefined or hidden cost that could cause problems later. The business plan helps the business to make day-to-day decisions on its operations. Teamâ€Å"D† will analysis Guillermo’s alternatives and make a recommendation on which alternative will enhance the businesses financial decision. Maintain Current Operational Levels One option available to Guillermo is to make no adjustments to the company’s current operations. This option supports the top concerns of acquisition from a larger firm and spending a large amount of cash on high-tech equipment investments, it does not solve the problem of a shrinking profit margin because of a rise in labor costs. Supporting the option to maintain current operations overlooks potential opportunities that are identified to allow the company to move away from its primary manufacturing role and act as a distributor for the Norwegian competitor. According to the assets, liabilities, and equity information provided by the University of Phoenix, sales growth is slowing to 1% from previous periods. These low profit margins willnot sustain Guillermo in the long-term;they will not improve if there is not a choicemade to adjust to the financial situation. Maintaining current operations does not address the shrinking profit margins. To continue to move Guillermo furniture in a positive direction, Mr. Navallez needs to apply some options already available and within the current operating structure. One option available to Guillermo is expanding the patented flame retardant process already in use within the manufacturing process, by applying a similar coating. This option requires no additional investment because Guillermo owns the equipment as part of the existing manufacturing process. The new coating adds value to the furniture, and makes it more appealing to consumers (University of Phoenix, 2009). The net present value of the project must be calculated in order todetermine ifthis is a strong option. For planning and budgeting purposes, a three-year life cycle is assumed for the coating project with an initial investment cost of $222,705 that is absorbed during the first year of the project. This produces a projected cash flow of $1,733,562, leaving Guillermo with a net income profit of $42,557. Net present value for the three-year project calculates to $197,171. Another option available and immediately implemented is to reduce inventory by quickly turning over products, thus increasing the cash flow. Planning an accurate budget supports the inventory overhead by reducing costs associated with maintaining inventory. The flex budget data shows that Guillermo furniture underestimated June operating expenses by $101,740. If these costs estimates were more closely tied to production costs, a substantial amount of cash would have been available to reinvest in other areas of the business. Closely managing this inventory will make more cash available for expansion in other areas of the company. Last year Guillermo experienced a $3,671 increase in its year-end inventory. Keeping a large amount of inventory on hand ties up cash, which otherwise can be investedin other areas of the business. Guillermo’s option to hold fast and maintain current course is setting the conditions for failure. However, to maintain its current course and improve its financial standing, Mr. Navallez can leverage small opportunities that maximize the financial condition by leveraging the existing patent and reducing inventory. High Tech Business Upgrade Guillermo’s high tech alternative is based off a process currently being used by one of the Norwegian competitors. It will allow the business to increase productivity but will also require a more skilled worker to operate the machinery. In choosing this alternative it predicts that sales will increase by 50% bringing in an increased revenue stream (University of Phoenix, 2009). In assessing this alternative looking at the net present value of future cash flows will help make this decision an easier one by noting the value it brings to the organization. Assuming that Guillermo expects to see a return on the investment within three years, this time period will be used in calculating the NPV. Using the three year time period with an interest rate of 7. 5% and a growth rate of sales at 1. 0403% the NPV can be calculated at $617,178. The firm’s predictions on projected sales has not been the most accurate when looking at historical information. Conducting a sensitivity analysis will further help to determine the value of this alternative using the net income as the adjusted variable. Assuming there will be a best, worst, and most likely outcome to future sales revenue, the projected sales number of $195,564 will act as the most likely outcome. By increasing this number by 10% and decreasing it by 10%, the best case and worst case scenarios can also be calculated respectively. These numbers will show how sensitive the NPV calculations are to the changes in net income. Under the best circumstances high tech alternative yields a net income of $215. 120 while the worst yields $176,008. These numbers translate into net present values of $617,486 under the best circumstances and $616,870 under the worse circumstances. If Guillermo decides to use the alternative funding for the expensive machinery becomes an issue. There are three main ways in which to fund the purchase of this equipment and the additional cost of employee labor. The additional costs can be self-funded if the available cash is available. This will increase the equity in the firm but this will also reduce the leverage the company currently enjoys. The company’s equity can be used to purchase the equipment. This will have the same effect as if Guillermo used personal funds since he is the sole owner of the furniture company. The equipment can be financed through secured debt financing which will increase leverage as well as provide additional tax benefits to the organization. And lastly, Guillermo can lease the equipment. Each of these alternatives provides unique tax benefits as well as pros and cons specific to each of these options. As Guillermo considers this alternative in comparison to other options the cost of maintenance, salvage costs, depreciation costs, and increased labor costs should be factored. These all impact the overall capital budgeting decision faced by Guillermo Furniture. Distribution/Broker Opportunities Guillermo’s second alternative is to become a broker for one of the Norwegian competitors. The company has been looking for channels to distribute in North America as it has chosen not to operate furniture outlets but instead to rely solely on chain distribution (University of Phoenix, 2009). Guillermo’s existing business relationships afford him the opportunity to coordinate a distributor network that generates a new form of revenue for the company. This new stream of income can help offset some of the financial challenges that have emerged as a result of a competitive furniture market and increasing costs. In addition to becoming a broker, Guillermo can also continue offering some of his high end custom products. To determine if becoming a broker is the best option, Guillermo will evaluate the NPV and WACC for the proposed project. To calculate the NPV, Guillermo must consider the investment time period and the discount rate. In this case, Guillermo will review a period of 20 years. When calculating, the need to remove the income tax from the net profit and then re-add the depreciation back in. Next, consider the value of the company’s equipment. For the purpose of this paper, it will be assumed at $100,000,000 with a straight-lined depreciation of $100,000 yearly, over a 10 year period. Once the ten years is complete, the before tax income will increase for the broker option by $100,000. The cash flow will be reduced by 42% since Guillermo will have to pay the taxes on the increase. Since the building will be completely depreciated after 17 years, the net income before taxes will be $50,000. The net present value for the broker option over the 20 year period at 10% will be $4,125,109. 02.

Cable Modem Cloning Hacking Communication Computer Science Essay

Cable Modem Cloning Hacking Communication Computer Science Essay Cable modem is a communication device. This device allows us to connect our PC or laptop to cable Television line and receive data from operator at speed of 1.5 Mpbs or more. Data rate is much more then telephone modems (28.8 or 56 kbps) and 128 kbps given by ISDN (integrated services Digital Network). It is almost equal to Digital Subscriber Line (DSL) telephone service. Cable modem can is combined with set top box. With this combination channels could be watched on TV and internet could be accessed. In most cased cable modem are given by operator. They are not purchased by customers. Cable modem has two connectors. One connecter is connected to cable wall outlet. Other connected to personal computer or laptop. In some cased second connector is connected to set top box for TV channels. Cable modems do conversation between analog signals and digital signals. In other words it performs the task of modulations and demodulation. Although it do modulation and demodulation but it is a very complex device then telephone modem. Cable modem can be individual external device or it can be integrated with a personal computer of set top box. Cable modem is connected to a laptop or personal computer with a standard 10BASE-T Ethernet card. Cable modems are connected to cable operator with a coaxial cable line. Through this coaxial cable cable modem communicates to Cable Modem Termination System located at cable operator office. Cable modems can send or receive signals to Cable Modem Termination System. But cable modem cannot send or receive signal to other cable modems on line. Internet service bandwidth over cable TV line can be 27 Mpbs or more for downstream and 2.5 Mpbs or more on reverse direction. But main factor in speed is cables from operator office to customers homes and actual speed that operator has. If operator is only connected to internet at speed of 1.5 Mpbs in this case data rate at customer end would be near 1.5 Mpbs. Main cable TV providers are using cable modems to bring internet at customer home. Cable modems are used to provide internet service to individuals and business customers. Fast internet connection can be provided by cables modems as well cable modem is a continuous connection. How cable modems work News, entertainment and educational programs are brought by television in millions of homes. Many peoples watch TV through cable TV in short known as CATV. Cable TV operator provides many channels and in very good picture quality. If customer wants cable TV operator can also provide access to internet with high speed. Cable modems are able to give competition to asymmetrical digital subscriber lines (ADSL).it is very interesting to how these both competitors works. In next topic I will try to explain how many TV channels and web sites flow on single coaxial cable. 1.1.1 More Space Coaxial cable used by cable operators is able to carry hundreds of megahertz of signals and each channel that travels on coaxial cable is given 6 megahertz of total electrical space or bandwidth.it means coaxial cable can carry many more channels then we can or wants to watch. Cable TV operator sends signals of various channels each channel gets six MHz slice of coaxial cables available total bandwidth. There could be two types of distribution of cable network. In first one coaxial cable is installed from operators office till customer home. In second type fiber-optic cable is installed from operators office till different areas then from these different locations coaxial cable is installed till customer home. 1.1.2 Streams If a company provides facility of internet then internet service can also use same coaxial cable. This work is done by Cable Modem by putting downstream data (data that is sent from internet to customer) on a six MHz channel. So internet data is just like a TV channel on cable. Same amount of total cable bandwidth is taken by internet downstream data as by a single TV channel. Internet service is a combination of downstream and upstream (data that is sent to internet from customer) .it means upstream also need bandwidth of cable. It takes only 2 MHz slice of space from total available space because it is assumed that customers download more data as they upload. To put these two types of streams (downstream and upstream) cable operator needs only two devices. One device at customer end that is called Cable Modem and other one at operator end called Cable Modem termination system. Computer networking and internet access management takes place in between these two devices. 1.1.3 inside the cable modem As mentioned earlier Cable modem can be external or internal to computer. Some operators provide Cable Modems those are integrated with set top box. Cable Modems can be different from their outer look but all of them have same components inside. Components are given below 1. Demodulator 2. Media Access Control Device 3. Microprocessor 4. Modulator 5. Tuner 1.1.3.1 Tuner The tuner is connected to cable outlet. In some cases tuner is connected to a splitter. Splitter separates channels used for data from channels used for cable TV channels. Tuner collects data from internet channel. Data comes in form of digital modulated signal. Tuner receives this data and passes this data to demodulator. In some Cable Modems tuner contain one other component known as diplexer.it allows tuner to divide frequencies into two sets. First set is used for downstream traffic ad second one is used for upstream traffic. Range of frequencies used for upstream is between 5 to 42 MHz. Range used for downstream frequencies is between 42 to 850 MHz. In some other cases Cable Modem tuner is only used for downstream data and for upstream traffic dial up telephone modem is used. In any case tuner passes data to demodulator. 1.1.3.2 Demodulator Typically Demodulator performs four functions. First function is to convert radio frequency signal in to simple signal that can be processed by analog to digital converter. Radio frequency signal contains information in it by varying amplitude and phase of wave. Second function is performed by analog to digital converter. It takes signal from quadrature amplitude modulation demodulator in turns in series of 1s and 0s. These 1s and 0s are in digital form. Third function is performed by error correction module. It receives information from analog to digital converter and checks this information against a already known standard for possible errors. Main function of this module is to find problems in transmission and to fix them. At this stage data is in groups and these groups are called frames. Frames can be MPEG format. So MPEG synchronizer does its duty to make sure that frames are in order and in line as they were transmitted. 1.1.3.3 Modulator Modulator do reverse job as done by demodulator. It converts digital data into radio frequency signals. So that they can be transmitted on cable. Nature of traffic that flow between user and internet is irregular. Typically this component has they parts 1. Digital to analog converter 2. Quadrature amplitude modulator 3. Error correction information inserter 1.1.3.4 MAC Cable modem has two portions upstream and downstream.MAC is lactated between these two portions. It works as interface between hardware and software portions of different network protocols. Every network device has MAC. Cable modem MAC performs much more complex task then normal MACs. Because it performs much more complex tasks it work load is given to CPU of Cable Modem or to CPU of user personal computer or laptop. 1.1.3.5 Microprocessor Job of Microprocessor depends on for what cable modem is designed. Cable modem can be designed only to provide internet access or it can be designed to be a part of large computer system. If Cable modem is used only for internet access then Microprocessor of Cable mode does most of function of MAC. In case Cable modem is used to be part of large computer system Microprocessor of computer performs most function of MAC. 1.2 Cable Modem Termination System At CMTS end traffic comes from different users in groups. Function of CMTS is take all traffic on a single channel and route this all traffic to internet service provider for connection to internet. on CMTS end service provider could have set up different servers for performing following functions 1. Account and Log management 2. Dynamic Host Configuration Protocol 3. Administration of IP Addresses of users 4. Servers for Data over Cable Service Interface Specifications Downstream data reaches to connected users. It is same like in a Ethernet network. Individual connection has to think that it is for him or not. It is totally different in case of upstream data. Data send from one user to internet is not seen by other users on network. As we know there is not so much bandwidth for upstream. Total available bandwidth is divided into time slices. Time slices are in milliseconds. Time slices are given to different user to send data to internet. Time slices works very well for send short commands, queries and address those are send from users to internet. Typically CMTS allow 1,000 users to connect to internet on a single six MHz channel. Normally single channel have capacity of 30 to 40 megabits per second. So it clear that Cable modem is able to give speed to customers which is much more then dial up modems. Single channel concept could also lead to some issues those customers can face. 2. History of Cable Modems At stating of year 1990 world started to know about stuff that could be possible with digital communication. At that time internet was known just as a tool. Engineers were trying to discover a method to shuttle digital signals between two computers. Same stuff is available for us today in form of internet, email and much more. Technology was invented but not for sending receiving email or surfing web instead it was invented to transmit television channel signals. Channels like ORF, ATV, Plus 4. These channels were transmitted on high capacity wires. At user end a TV box was used to handle these channels and deliver to TV. It was starting of cable TV. To get more TV channels so much efforts are done in last many years. Physical network of coaxial cable and fiber optic cable are installed in many kilometers. These physical networks are installed either underground or some feets over ground using wooden or iron poles. And of course these networks have worked very well to full fill their purpose. Cable TV was born in U.S. but it has rapidly migrated to other continents. Now a day cable TV networks are pumping more than hundred TV channels to homes. One of leading cable operator in Vienna is delivering 132 TV programs including 23 HD programs.[upc.at] Later on inventors wanted to use cable TV network for other purposes. That was time when computer network started to stand on its feet. Means computer networks were started to build in organizations and in educational institutions. Some organization had proved that two or more computer connected to each other can do amazing things. Data or information that was only in individuals computer can be shared between others also can be enhanced by other users. Books were made free from library and published so that all can see. To make it possible that two computers can talk to each other so much was done by inventors. Communication protocols were developed. Languages to develop protocol were invented. Standards of communication were developed. Names were given to standards such as Novell and Ethernet. This all was rising of local area network. At this time engineers and investors started to think about increase boundaries of this information communication network. They wanted to share that was going on in computer of an organization at a wider geographical area. They were thinking to share information of a computer with another computer located at other end of same city. They wanted to transform a local area network in metropolitan area network. All these idea needed transmission medium installed within a city.so that information or data can be send or received on wide spread transmission medium. One solution was to transmit information on copper wires of telephone networks. But copper wires used in telephone network were not able to provide speed that was provided by LANs. Fast speed transmission was provided by advance version of telephone system called TI ,T3 or ISDN. But these solutions of high speed information transmission were very expensive. Luckily same types of cables used for local area networks named coaxial cables were already been installed in all over the city by cable operators to provide TV channels to customers. With some more engineering this cable can be used as very power full media for information transmission. A electronic device was demanded by many organizations and educational institutes. Private and government organizations, schools, hospitals, were looking for a way to send and receive text file, images, across town. Some of them rented expensive lease lines from telephone companies and some of them created their own pipes to transfer data or information across town. But peoples were not aware that there was a medium that was able to data with high speed as well it capable to transfer data on very high speed. This medium was not far away it was just outside in street. Cable TV operators had built a network across city. It was supposed that it was only for transmission of TV channels. But it was very much suited for information as well. It took many years to discover that cable TV network can be used for transfer data across city. LANcity discovered technology that became mile stone for so called Cable Modem. In other words It was just a box that was attached to cable television that was able to transfer coaxial cable a medium to transfer TV channels to medium to transfer data. As many people wished about its speed it was outstanding. It was a big coincidence that almost on same time an another force that attracted attention of peoples was introduced. Its name was internet. Typically cable modem technology was developed so that peoples can share files between offices those were located across city. Combination of internet and cable modem technology connected households with high speed. As it happens to all most all technologies same was with cable modems that it took many years to come in shape that is available for us today. Modems those were made in its early days were big metal boxes and were very heavy to pick up. In early years size of cable modem was almost same as rack of our cupboard. Main idea was they were not made for homes or residential use. They were made for schools, offices and for educational institutions. Not at all for homes. In those days internet was just a linking of government offices and educational institutions. Speed of internet was very slow over dialup phone lines. Computer monitors were also black and white. Operating system of systems was also DOS. It was not windows. There was no world wide web available. Internet was a toy for peoples who were interested in technology or of peoples who were interested to explore new technology. Internet has nothing for everyone. Those days were starting days of internet. 2.1 Development of Cables Nothing would be wrong to say that in those days personal computer were babies. But cable television networks were in their 30s. There was more than one cable operator in same area. Most of cable operators were offering more than 50 channels. Some of cable operators were providing service with basic TV channels on the other hand some were providing TV channels with basic channels as well premium TV channels. Architecture of cable network was totally different as it is today. In these days fiber optics is being used and it has increased speed of transmission lines. Noise that was introduced by amplifiers has reduced. Combination of fiber optics and coaxial cable are doing a under full job. But at starting some peoples believed this combination will never work. With time there are many changes have taken place in technology but still one technology is still same. Pictures of TV channels are taken from air as they are broadcast from satellites. At operator end TV channels are captured from air then they are passed through a so called mixer it place them on a single cable on different frequency bands. Now they are ready to travel on coaxial cable. But after traveling some miles they should be amplified. But here is a problem amplifiers also amplify or boost noise as well. This noise introduced by amplifiers make the picture worse. In 1980 cable networks were like branches of tree. It means from main office of cable operator thick cables were going to all four directions. After a particular distance in each direct less thick cable were used till different branches of cable operator. Thin cables were used till customer home from branch office. This was architecture of cable TV networks. It was perfect to transmit TV channels on it. There were many reasons that this network was not suitable for data communication. In a sense it was one way network. As we mentioned there where many reasons one of them was TV signals were sent only in one direct means from cable operator office to customer homes. To send signal in other direction means from customer to home cable TV operator was not possible. This network could work with data transmission if there would a method that customer or users can also send data to operator office and from operator office to destination of data it could in same city or in same country or could in other country for example world wide web. Till 1980 most of cable operator had not started to make path for customer to send data toward operator office. It was called upstream. Downstream was already possible as channels were sending from operator office to customer homes. Operator were not thinking about it one reason behind was there was not enough demand of it. So without any demand operators were not ready to invest their money in this technology to make path from customer home toward operator office. But it has not affected developers in any way. They continued their inventions in this technology that could make coaxial cable more useable. It was their main interest to make this cable TV network useable for information transmission. Information can travel in both directions not only in one direction. There was a requirement of an electronic device that could combination all stuff of data communication with cables used for TV channels. This electronic device should combine whole architecture of cable network with data c ommunications. So lot of efforts was required to transform cable TV network in to data network. Cable modems those were invented in 1980. Typically were not addressed a Cable Modems. They were so called radio frequency modems. They were not made for home users. They were used only by engineers. They were cable able to perform of modulation and demodulation. Information transmitted by them was 1s and 0s. It was not video means were not TV channels. Information was transmitted in coaxial cable within same boundaries of frequencies. Cable modems those were invented in their early days were used for different purposes. As cable networks owned by cable operators. Only some of cable operator agreed to negotiate within a city to link different buildings. These building can be educational institutions, police stations. These building can send or receive messages to each other by using existing cable network. At that time cable modems were only capable to deliver a speed of 19.2 kbps. But it was still faster than speed given by telephone modems that was around 1200 bps. Interesting thing is after 30 years we can enjoy speed of Mpbs. Cable Modems made in starting days were not so complex as modems those we have now a day. They were very less sophisticated as compared to todays modems. Let us suppose there are two computers in two different buildings attached to each other with cable modems over cable network coaxial cable. A message is sent from first computer. Computer handovers message to modem. Modem hand over this message to destination computer on downstream frequency without any processing. Basically it is broadcasted to all computers over network. Destination computer gets message through cable modem. As well all other computers on network get the message. But they cannot see messages because address of computer does not correlate with messages destination address. Transmission was based on a simple logic. One computer wants to send message to other computer so called Mr. ABC it will send message to all assuming that all are Mr. ABC but only Mr. ABC will receive message because other computers are not Mr. ABC. Till this time cable TV operators started to recognize capabilities of their wide spread coaxial cable network. They started to use cable modem for their own communications. Some of main branch offices were not near to telephone lines. Cable operators had covered remote areas as well mountains. But telephone lines were not available on these places. So cable operators thought they will use their own cables for communication on these remote areas rather than paying to telephone companies for installing telephones line in those remote areas. They have one choice to use cable modem on both end of their cable network. It was cable modem that allowed to cable engineers to set up internet PBX using cable network. Till now a day in some places those modems are used for telephone service. This was the time when data was available with phone and TV channels were already available. After some time developers of cable modem discovered a modem that was able to provide speed of 1.544 Mpbs speed over cable network. They took advantage of it started service of leased line known as T1 for businesses. T1 lines needed bandwidth on cable as equal to one TV channel. Luckily some of cable operator have free channel available. Those operators do not have vacant channels thought to replace some of channels so that give service of private data network to their customers. Research done on history of cable modem shows that it took 15 years and then cable modem became main stream. Main three problems were faced in long path of development of cable modems. First problem was transmission of traffic in both directions. It was possible with cable network to transmit information from operator office to customer homes but transmission of information from customers toward operator office was not possible. Till late 1990 cable operstor were capable to transmit information in both directions. Second problem was with business model. As already mentioned data transmission was made possible by cable modems but it was only use full for organizations or educational institutions like universities or schools. It was not available for home users. At that time it only looked as a business have only cost but no profit. Third problem was modem itself. In most cased it was built by different companies according to their requirement for single application. It was property of supplier. Modems from different suppliers were not able to communication with each other means no interoperable. In simple words it means cable companies were investing in such a technology that have no standard and it can be overcome anytime or other technology. Answer of these questions was given by DOCSIS. DOCSIS stands for Data Over Cable Service Interface Specification. It defined that cable modems are for cable industry. They are not for researchers or developers. DOCSIS helped for development of cable modems in direction of economy and volume. 2.1.1 DOCSIS Till mid of 1990, three problems those occurred for acceptance of cable modem were being solved. Upstream path from customer homes to operator office were being added to coaxial cable network. News from Cambridge and Castro valley encouraged cable operators to know more about cable modem technology.it also helped them to explore business model. Use of cable modem in telecommunications business was also favorable for cable modem development. Internet was rising day by day. Cable TV and telephone companies had tuff competitions. Companies were trying to get each other customers. Companies were able to provide TV channel service as well telephone service. At this time there was a new business for these companies it was internet service for customers at high speed. But still there was one barrier for companies. It was device interoperability. There was a lack of standard in modem industry. It was not possible to get interoperability without standards. Cable modem market could not be emerged without standards. Cable modem developers had a feeling of fear without standards to manufacture a big volume of cable modems. Because of production of less quantity price was high and it directly affected customers. It was well understandable and as well expected that electronic devices should work no matter of their location. In other words if we buy a modem from Vienna it should also work in Graz without any trouble. Because lack of interoperability if a modem purchased from Vienna and then customer moves to some other city where cable service is provided by another operator and this modem will not work there. I would like to give a sweet example here may be you have experienced of different power outlet in different countries. It is obvious no retailer would like to sell such products those give trouble to face angry customers. Interoperability was main issue at that time and it depended on technologies those developers had chosen those days. Some manufactures were selling asymmetrical modems. It means information moved faster from operator office toward customer home as it moved from customer home to operator office. Reason behind was a click to get a page from web needed less bandwidth as required by webpage itself. Some other manufactures had different ideas they were producing symmetrical cable modems as broadband user were increasing. Their idea was that home user would need more upstream speed to send information toward word wide web. Cable modem suppliers were growing with same speed as high speed internet grew. Every supplier was bit different from other. Some big names of electronic devices like Cisco Systems. HP, IBM, Motorola jumped in industry of cable modems. There were also small manufactures in cable modem industry. When big companies entered in market, small manufactures where afraid because big manufactures can produce modem like cookies. They could offer price very much attractive for customers. Still small suppliers tried to move on as quickly it was possible for them. This all was happening in non-standardized environment. In 1995 only one mantra was on everyones tongue and it was standards for their technology. When it did not worked as it was in mind of big manufactures like HP and IBM they step back from scene. In those days standards for cable industry were only concern. Because it was related to electronic devices those were used in homes. Cable operators has only fitted cables and modems in their offices and at customers end only from short listed providers of cable and modems. It made possible coexistence of both suppliers and cable service provider. Main suppliers have full control over selecting pricing and features of cable modems. It totally up to them to decide when older version would be discontinued and newer version would be introduced to market. At end of year 1995 some of cable modem engineers started to does private meetings about a chip call MIcroUnity. Same like other chips it was also reprogrammable. They decided to use this chip in cable modems as well in set top boxes and later on if required it can be updated with software. It was an alternative for if new services are introduced then cable operator should change box. It have double cost first cost was of box and second one was to send one to install new box. At that time there were two main players in cable technologies. Both of them thought enough about this MicroUnity chip that was reprogrammable then they decided to invest in this chip. They formed a private company that would lead for use of chip in cable hardware. This company was called Cable Multimedia Cable Network System in short MCNS. Motivation behind MCNS was to attract more hardware suppliers in cable industry. So that pricing can be bring down and to introduce more features. Only reason to do so was to bring interoperability among cable device producers. only solution of Interoperability between devices from different operators was to develop standards. Later on MCNS became DOCSIS Data Over Cable Service Interface Specification. It is pronounced as dock sis. In year 1996 Developers put it on fast track and they decided to complete specification written till end of year 1996. At mid of 1997 specification were being completed. Lab test can be performed on specifications. Intension of these tests was give sample to vendor and to test specifications. It was September month of year 1997 when a detailed certification program was released. Responsibility was given to a board to review certification. It was also responsibility of board to approve products if they meet specifications. An agreement was made that Cable Modem Termination Systems would be check to qualify specifications and vendors would be tested to give me certificate. As certificate they will get DOCSIS certificate sticker. 2.1.2 Certification Two years and to clear three certification test were necessary for any vendor to get DOCSIS certificate. On 20 march 1999 cisco system got qualification for their CMTS. First certificate for modem was issued to Toshiba and Thomson companies. After some months modems from 3Com and Arris passed certification. In coming some months many products get DOCSIS certificate. Now a day in many country cable companies lead DSL reson behind is speedy efforts done to make DOCSIS standard. Meanwhile stories of success of cable modem and high speed internet were coming continuously. Peoples who adopted cable modem in its early days were satisfied from their decision. Cable modem industry was afraid if they would be able to full fill high demand. Because of fast progress of cable modem technicians were also in high demand. Two persons were need first one to handle cable modem and second one for handling personal computer. At end of year 2002 in North America there were around 16 million customers. Cost of cable modem was also reduced from 1990 since 2001. In year 2001 cost of a cable modem was around $120 while in year 1990 it was $500. There is no dispute either on success stories of cable or on its high demand. Investment banker signed agreements with leading cable companies to build backbone network and content infrastructure to support high speed cable modem technology. Development of DOCSIS is still continuing. Now a day Circuit of cable modem is available on personal computer cards. In Europe cable modem circuit is available in set top box. With the time successor of DOCSIS were released. Quality of service has in improved in successors of DOCSIS. They are able to support coming generation of high speed internet service. DOCSIS has also played very important role in development of internet protocols. Latest version of DOCSIS is DOCSIS 3.0 that is able to provide download speed of 1.5 Gbit/s and upload speed of 1150 Mbit/s. Trial version of DOCSIS 3.0 was announced o

Mirror Dance :: essays research papers

Mirror Dance There are some paintings that simply capture the essence of life within their still frames such as the painting of the "Mirror Dance" in R.A. Salvatore’s novel Crystal Shard. The painting depicts two characters set in a darkened background. The faint light of the moon casts shadows down upon the grassy floor on which the sylvan warrior and human assassin battle. The glimmer of the moon reflects upon a small, nearby pool of water. A silver sparkle in the distance marks the nearby city of Silvery Moon. A sneer of hatred is etched upon the face of the human assassin. His eyes glimmer with a taint of red to depict his blazing internal rage. The clothing worn by the human is black as the night, much like the hooded garbs of ancient Japanese Ninja, the only hint of color coming from his weapons. One of his hands holds a vicious blade, blackened like the coal inside a fireplace. Small flecks of crimson blood decorate the tip of the blade, matching the fresh cut upon the arm of the elf. The legs of the human are crouched, as if he were ready any moment to leap savagely at his opponent. His secondary hand hosts a second blade, much smaller than the other sword, his hand holds the secondary blade inward, as if to flick it out at his adversary. The elven warrior casts an extremely different perspective upon the viewer. His eyes twinkle with the soft moonlight, and his smile welcomes the fierce battle. The warrior’s robes flutter in a soft breeze, shining in the glow of the night. Even with his arm bleeding red from a cut which must have been inflicted by the assassin, the warrior still maintains a look of regality. The crown adorning the top of his head, marks his royal heritage. The weapons commanded by the warrior seem to take on a life of their own, his sword dancing to meet the twin blades of the assassin while a radiance resonating from his shield, cast light upon the foe who prefers the stealth of night. Nature lies still for the battle between the two adversaries. The birds in flight, bend away from the loud clashing of swords, and the deer hide amongst the trees in the forest. The people of the distant town of Silvery Moon watch from their doorways, huddled close to keep the chill of the night from freezing their bones. They look upon the scene with deep interest, the smiles of the children obviously cast upon their elven hero.

Interior Design as a Career Essay -- Jobs Careers

Imagine designing a dream home with all the color and space conceivable. This illustrates the work of an interior designer. A "schemer, intriguer, or plotter," could prosper in a career of design (dictionary.com, 'designer'). A career in interior design allows innate abilities of creativity and organization to be practiced in satisfying a client's desire for style and flare in their home or workplace. The work of an interior designer requires a natural skill to work with people and to decipher what a client desires. "The designer's job is to evaluate, plan, and design the interior areas of residential, commercial, and industrial places." (Careers in Focus: Design.) A few simple jobs consist of helping clients to select fixtures and furniture, supervising the coordination of colors and materials, obtaining estimates and costs within the client?s budget, and overseeing the execution and installation of the project. Some very important details designers must be aware of are the architectural requirements, space planning, and the function or purpose of the environment. In the past, there have been many famous artists, but few of them contributed their artistic skills to the design of the home. Michelangelo was a famous interior designer who created the most magnificent places for the richest of people. He made quantum use of his beautiful sculptures and paintings to create a rich ambiance. This is how interior design first began as a career. Years later, furniture, draperies, and wall coverings were included. Elsie de Wolfe was the first to practice interior design in the 1950s. Adam and Louis Comfort Tiffany, two American brothers, began a company to create beautiful furnishings and art, especially stained glass. The ... ...s estimated to be at $39,180 annually. The highest paid ten percent of interior designers, experts, in 2002 had wages of $69,640, while the lowest paid ten percent, beginners, were paid $21,240 (U.S. Department of Labor). Those who are genuinely committed to a fulltime career in designing know that urban areas and big cities pay better and provide more career options. In small town areas there is less demand for the input of an interior designer. Self-employed designers work for clients at a set, hourly fee, but majority of designers work in a firm for either a straight salary or an hourly fee to clients. In interior design, because there is so much flex given to each designer in a firm, there really are no requirements of benefits, insurance, or retirement plans. The established benefits are completely up to the individual employer. (Careers in Focus: Design)

pvr demand stretch :: essays research papers

Various Strategies Used By PVR For Stretching Supply To Meet The Demand This Strategy involves altering and aligning the organization capacity to meet the demand i.e. when demand for services is at its peak, capacity is expanded and when the demand is low, capacity is reduced to conserve the organization resources. The primary services resources that can be expanded and contracted temporarily to meet the demand are discussed below: 1)  Ã‚  Ã‚  Ã‚  Ã‚   Time 2)  Ã‚  Ã‚  Ã‚  Ã‚   labor 3)  Ã‚  Ã‚  Ã‚  Ã‚   Facilities 4)  Ã‚  Ã‚  Ã‚  Ã‚   Equipments 1) Time: PVR brought in the concept of flexi-hours and it has eliminated that old traditional show timings of 9-12am,12-3,3-6 etc. They came with the odd hours show timings like 10:50, 2:20,3:40,7:25 which suits the requirements of different type of viewers. Like school bunkers can go for 10:50 am show, college going students after attending their classes can view 2:20 pm show and on the other side corporate executives can go for 7:25 pm show. 2)  Ã‚  Ã‚  Ã‚  Ã‚  labor : Labor is one area where an organization faces major constraint when demand changes. In case of high demand period like summer vacations ,week-ends, PVR increase no. of employees by hiring part-time employees during peak period. They increase the no. of employees at the ticket counter, inside the auditorium, and at the refreshment counter. They are adopting Cross training i.e one employee is trained in more than one job, like person sitting at ticket counter also do the job of usher. 3)  Ã‚  Ã‚  Ã‚  Ã‚  Facilities : In case of High demand PVR plan it out well in advance based on experience and increase the number and frequency of screenings. May be extending the screening in the next weeks schedule.

Initiation Sylvia Plath

Chantal Chau Analysis of a Key Passage, Initiation by Sylvia Plath In Initiation by Sylvia Plath, the author suggests that conformity and having friends is a wonderful idea, yet the idea of having an individual identity and being an individual is stronger. In the excerpt, Millicent is slowly realizing that conforming and being a part of a sorority is not as exciting as it sounds, and being an individual offers more opportunities to become a unique person. Millicent is an average girl who no one really notices, when one day, a sorority group decides to allow her to join, but she must past their initiation test first.At first, Millicent is ecstatic, and proud that she can finally be a part of society, but slowing, and in the beginning of the excerpt, Millicent finds that being an individual can offer more. As she is talking to Liane Morris, another sorority contestant, she finds that in the sorority â€Å"they have a meeting once a week†¦ each girl takes turns entertaining at her house†¦ †, and how this is not all as exciting as she imagined. Millicent’s desire to know what the group does reflects the idea of hesitation, and how Millicent is now wondering if she really wants to be a part of this group.As she considers both sides of her decision to join, she realizes that joining the sorority would simply allow her to approach Herb, a male student she likes. Her thought â€Å"would he ask her out (if he ever did) just for herself, no strings attached? † bring the desire to be unique and original up and pushes past the need to be popular. Millicent is constantly considering the idea of not joining the sorority, and visualizing them as â€Å"pale grey-brown birds in a flock, one like the other, all exactly alike†. This analogy of conformity is very strong, because in a sorority, every girl is alike, with shallow personalities and beautiful exteriors.The sparrows are described to be â€Å"chirping†, which brings the idea o f being plain and restrained to the mind, because when birds are chirping, they are not expressing themselves; rather they are simply copying the other birds, with no desire to stand out from the rest. In Millicent’s mind, freedom and originality is described as â€Å"swooping carefree heather birds, they would go singing and cooing out across the great spaces of air, dipping and darting, strong and proud in their freedom and their sometime loneliness†. Heather irds are a mythological animal, meaning freedom has no defined description that originality does not exist in a solid form. They are described to be â€Å"swooping, carefree†, meaning there is no worry of being judged, and â€Å"dipping and darting, strong in their freedom† describes the happiness of a worry free life, where style and opinions are not judged or withheld, unlike the â€Å"chirping†, trapped, restrained sparrows which symbolize the sorority. Heather birds were â€Å"singing a nd cooing out across the great spaces of air†, showing that they could express their ideas and opinions without worry, though loneliness was a consequence.In the excerpt, it was stated that the heather birds were â€Å"strong and proud in their freedom and their sometime loneliness†, meaning that there will always be unique people in the world Millicent can relate to, though at times the individuality will stand out, and she will be alone. Through this mental debate, Millicent learns discovers that she could enter her imaginary great hall through â€Å"her coronation as a princess labelling her conclusively as one of the select flock†, or use â€Å"other ways of getting into the great hall, blazing with lights, of people and life†.When read closely, we can see that the mentions the sorority as a flock, demoting them to nothing but a group of beautiful shells with hollow insides, one alike the other. It is then that her decision to use â€Å"other waysâ₠¬  to enter this great hall, without being simply a hollow princes. Just before she is actually accepted into the sorority, the door to the basement opens, and the description of the â€Å"ray of light† that â€Å"sliced across the soft gloom of the basement room† shows the difference between identical, shallow girls and the deeper, unique members of the world.The ray of light that sliced across the room symbolized the epiphany she had, how she now knows that she cannot be a part of the â€Å"soft gloom of the basement room†, where everyone is the same, there is nothing special about anyone. As Millicent is leaving the basement, she hears the â€Å"song of the heather birds as they went wheeling and gliding against wide blue horizons through vast spaces of air, their wings flashing quick and purple in the bright sun† and in her final decision, her heart and soul joins the heather birds she has always been.From the beginning, Millicent has always seem to have known that she could never be a shallow pretty girl; throughout the story, there are little clues of her reluctance to be part of the sorority, such as when she was talking to Lou, a member of the sorority, and discovering the many useless things the sorority does. But when she realizes she has more than just one option, Millicent suddenly becomes hopeful, and more positives changes arrive, such as â€Å"how she could still be friends with everybody†, how she can still be herself, while still being in a group. The group of original people.

Phase Transformations in Metals

It follows that some of the parent phase volume disappears. * Transformation reaches completion If growth Is allowed to proceed until the equilibrium fraction Is attained. Two types of Nucleation 1 . Homogeneous: nuclei of the new phase form uniformly throughout the parent phase. 2. Heterogeneous: nuclei form preferentially at structural inhomogeneous, such as container surfaces, grain boundaries, insolvable impurities, dislocations, etc. Homogeneous nucleation: solidification of a pure material, assume nuclei of solid phase form In the interior of the liquid phase.There are two contributions to the total free energy change AC that accompany a solidification transformation 1 . The volume free energy Agave – which is the difference in free energy between the solid and liquid phases. Agave will be negative if the temperature is below the equilibrium solidification temperature. The magnitude of its contribution is the product of Agave and the volume of the spherical nucleolus (4/ 3 aorta ) 2. Surface free energy y: energy comes from the formation of the solid-liquid phase boundary during the solidification transformation. Is postlude; the magnitude of this contribution Is the product of y ND the surface area of the nucleus (nor) * the total free energy change GAG Is equal to the sum of these two contributions: GAG=4/3 aorta GAG_v+rattrap y * In a physical sense, this means that as a solid particle begins to form as atoms in the liquid cluster together, its G first increases. If this cluster (embryo) reaches a size equal to the critical radius, r*, then growth will continue with the accompaniment of a decrease In LEG. An embryo with a radius greater than Is called a nucleus.A critical free energy occurs at the maximum of the curve, which corresponds to the activation energy needed for the formation of a stable nucleus. Critical radius of a stable solid particle nucleus: ) Activation free energy required for the formation of a stable nucleus: ) This volume fre e energy change is the driving force for the solidification transformation, its magnitude is a function of temperature. At the equilibrium solidification temperature (or melting temperature) Tm, Agave Is O, and with decreasing temp It becomes Increasingly more negative.Agave temperature decreases meaning, nucleation occurs more readily at temperature below Tm The number of stable nuclei n*(having r>r*) is a function of temperature as well: 1 ) changes in T have a greater effect on than on he denominator. As T is lowered below Tm the exponential term decreases such that the magnitude of n* increases *another important temperature dependent step in nucleation: the clustering of atoms during short range diffusion during the formation of nuclei. The influence of temp on the rate of diffusion: high temp increases diffusion.Diffusion is related to the frequency at which atoms from the liquid attach themselves to the solid nucleolus, VT. Thus, low temp results in a reduction in VT. The nuc leation rate N is the product of n* and VT Heterogeneous nucleation has a lower activation energy than homogeneous because he surface free energy is reduced when nuclei form on the surface of preexisting surfaces. Growth occurs by long range diffusion consequently, the growth rate G is determined by the rate of diffusion, and its temperature dependence is the same as the diffusion coefficient (recall chapter that diffusion increases as temperature increases).Most phase transformations require some finite time to go to completion, and the rate is important in the relationship between heat treatment and the development of macrostructure * for solid systems the rate is so slow that true equilibrium structures are rarely achieved, equilibrium is maintained only if heating and cooling are carried out at SLOW unpractical rates. *for other than equilibrium cooling Superimposing: cooling to below a phase transition temperature without the occurrence of the transformation Superannuating: hea ting to above a phase transition temperature without the occurrence of the transformation

Current Issues in the Philippines Essay

According to the Greek philosopher, Plato, â€Å"Nothing is more important in human life as education. It is an indispensable necessity for mankind.† Education is the key that levels the playing field of opportunity between the rich and poor, amongst social classes and races. In the Philippines, the lack of education is the primary reason why it cannot move forward towards progress, and has led to social problems such as: scarcity of job opportunities, impoverished family life, and lack of environmental concerns among the marginalized members of our society. The lack of education of Filipinos living in the slum areas in major cities of the country is the void that keeps the gap between the rich and the poor. It is one of the major contributory factors that has caused the Philippines to remain as a third world country, aside from corruption in government. Our president, Benigno C. Aquino III, strongly believes that education is the first step that will lead the Filipinos to the â€Å"tuwid na daan.† The lack of education can be equated to poor job opportunities. Job hiring, nowadays, is highly competitive among fresh graduates. In fact, the degree or course of an individual is not only the basis for getting a good paying job, but from what university or college he/she graduated from. Hence, since good job opportunities are scarce for those who have not gone to school, low paying â€Å"blue-collar jobs† is the only means to survive. Most often, these people are the victims of contractualization from which they do not receive benefits as compared to regular employees, and the protection from the abuses of companies that give below daily minimum wage that is set by law. In the survey conducted by the National Statistics Office (NSO) in 2011 on Child Labor, it showed that out of the 29.019 million Filipino children aged 5-17 years old, about 18.9 percent or 5.59 million were already working, usually in hazardous conditions. For parents who lack education, they actually pressu re their children to work. Instead of sending them to school, they force them to do so in order to help in the family’s financial needs. It works to the advantage of companies, those cost-cutting with their labor over-head, to employ children at a low cost. In reality, even these children themselves are unaware of their rights. They choose to work because they witness the poverty in their own family for which they feel the responsibility to help. In the remote provinces, young women who lack  education are victims of white slavery or women trafficking, either domestically or abroad. They are forced by their parents who are bribed by recruitment agencies, without knowing that their daughters will be turned into sex slaves by foreigners or even local sex dens in key cities in the country. Out-of-school-youth is increasing every year as the population increases. There have been crime syndicates preempting these children to commit crime since they are protected by the â€Å"juvenile law.† Minors at the age of 15 who commit crime will not be charged of the crime committed in a regular court, but will simply have to undergo rehabilitation in the Department of Social Welfare and Development (DSWD). Because of this, crime rates committed by minors have increased in the past years since the conceptualization of this law. Another social impact of the lack of education is poverty. Since job opportunities are deficient, the financial status of the family suffers. Such condition leads to poor family planning, malnutrition, and juvenile delinquency. The lack of the basic knowledge on family planning has led to population explosion among the poor families. Statistically, large family size comes from the underprivileged families of the society. This is the result of the myth that the more children they have, the more chances they will have to be free from poverty if one of their children is fortunate enough to find a job that pays well. According to Plato, â€Å"No man should bring children into the world, which is unwilling to persevere to the end in their nature and education.† Parents must be mindful of their responsibility of sending their children to school in order for them to have a brighter future, and not by means of luck. The lack of environmental awareness is another detrimental effect caused by the lack of education. These poor families are also known as informal settlers that reside in slum areas. They have created environmental problems such as air pollution, water pollution, flooding and congestion. Since they are formed in an environment where exposure to all kinds of pollution is highest, they usually operate outside society’s norms where environmental laws are not strictly enforced. They are situated along river lines or seashores which are frequently affected by typhoons, rains, erosion and sea  surges. Not only does is this harmfully affect their environment, but also their health. The risk of over-crowding along rivers and the narrowing of our floodway system, the garbage pollution they contribute everyday lead to disease outbreak like dengue, flooding, and casualties during typhoons and heavy rains. For a family of a deprived household with more mouths to feed, children also become victims of malnutrition. Improper nutrition affects all body systems, from physical growth and vision, brain vigor, and immunity. According to the survey conducted by the Food and Nutrition Research Institute (FNRI), Filipino children suffer from micronutrient deficiency: Vitamin A, iodine and iron. The lack of Vitamin A affects eye health, while iodine affects cognitive functions and iron for fighting anemia. These defects have been mostly rampant among children of distressed families. Lack of education is one of the major reasons why there is poverty in the country. To level the playing field of opportunities to every Filipino, I suggest that the government provide free and quality education to every child. The K-12 program in our educational system is one of the best initiatives this administration has done. The underprivileged children can now compete with children in exclusive schools, since they now have the same foundation of nursery and kinder education in preparation for a free grade one to seventh grade education given to them by the government. The passing of the RH bill is also a positive move the present government has done to address overpopulation. Relocating informal settlers to a safer community environment is a long term remedy for the issue of over-crowding, flooding and health risks. As mentioned, education is the only way to level the playing field of opportunities between the rich and the poor. As Plato said, â€Å"Every boy and girl must be educated to his/her limit. Education, therefore, should be provided by the state not by parents.† The government’s K-12 program shows its determination to provide every child the right to education. What matters here is the full implementation of the programs that would benefit every child, especially those in the farthest corners of the country. Plato perceived education â€Å"as the total development of a man: mind, body, and soul by using every possible means.† Knowing the capabilities and ingenuity of every Filipino, through education, we can help the Philippines become one of the leading countries in Asia in the coming years.

Lower Quadrant Sport Injuries - Rehabilitation program for Grade 2+ Essay

Lower Quadrant Sport Injuries - Rehabilitation program for Grade 2+ Adductor Muscle Strain - Essay Example He was afraid to make movements and told the physiotherapist that he had lost his confidence in his ability to return to his previous level of sporting activity. I checked if the groin muscles of the patient were tightened due to the injury. The muscles usually tighten the next day after the strain. The intensity of pain was checked in the groin area where the adductor muscles are located. Swelling and bruising was checked which was present. Then I checked for contraction of adductor muscles by squeezing the legs of the patient together. I was not able to contract his adductor muscles and a gap was felt in the adductor muscles. He felt pain and discomfort on stretching the muscle (Knaniik T., Tones B, Bauman C, et al). Pathophysiology The hip adductor is a group of powerful muscles which acts to pull the legs together. There are five adductor muscles namely: pectineus muscles, brevis muscles and longus muscles (these are the short adductors that go from the pelvis to the thigh bones) , Magnus muscles and Gracilis muscles (these are the long adductors which go from pelvis to the knee). These muscles are innervated by the obturator nerve except pectineus muscle which is innervated by the femoral nerve(L2- L4) and the Magnus adductor is also innervated by the tibial nerve (L4- LS )The groin strain on the hip adductors could rapture any of the muscles. (Fry, Bruce, F. 2009). I informed the patient that he had grade 2 Adductor muscle strain as he had swelling, bruisung and felt pain when it was touched. He was not able to run the way he used to before but could walk with some support till his torn muscles joined again. He was told that it would take four to five weeks for him to return to his sports activity. In grade 1 strain, a person feels mild discomfort, slight tenderness but swelling is not present. In grade 3 strain, a person presents with lots of swelling and in not capable of running or even making slight motions. A groin strain is a partial tear of the sma ll fibers of the adductor muscles. The adductors are a group of three muscles located on the inner side of the thigh. They start in the groin area and run down the inner thigh to attach to the inner side of the knee. http://www.sportsinjuryclinic.net/cybertherapist/front/frontthigh/adductorinflam.htm Before the start of the treatment I asked the patient to get a MRI scan done for me along with his physician to study the depth of the injury and thus plan the treatment according to the severity of the injury to the muscles. After examining the groin area with the help of X-Rays and movement of the muscles, the footballer was advised ultra sound treatment by ultrasound therapists. Ultrasound Therapy Ultrasound therapies are used by therapists to treat soft tissue injuries. The therapist used ultrasonic waves (sound waves of a high frequency). The waves were then moved over the surface of the skin in the area affected by the injury. A special ultrasound gel was placed on the skin to ens ure maximal contact between the treatment head (the instrument producing the waves) and the surface of the skin. The benefits of ultrasound therapy include reduction of the healing time of the soft tissue injuries. It fastens the normal resolution time of the inflammatory process by gathering more mast cells at the site of injury. The application of ultrasound is not advised immediately after injury as it may cause an increase in blood flow. Increased blood flow is beneficial in the sub-acute phase of tissue injury. Ultrasound treatment is advantageous for patients with strains as it stimulates the production of more collagen which is the main protein component in soft tissue such as tendons and ligaments. This way there is acceleration in the proliferative phase of tissue healing. The treatment through

Housing and Benefits for Asylum Seekers in UK Essay

Housing and Benefits for Asylum Seekers in UK - Essay Example Housing is at the very cornerstone of reception and resettlement (BRC 1987, 96-99; Carey-Wood etal. 1995, 66-72; Majke 1991, 267- 283; Refugee Council 1997; Robinson 1993, 170-186) and controlling access to housing has become an increasingly important part of the government's asylum and immigration strategy. Without adequate shelter, few other opportunities exist for those unfortunate enough to be destitute. With no permanent address, there is little chance of establishing the minimum rights of citizenship, which offer inclusion into the host society. Social exclusion has been a reality for many thousands of asylum seekers over a prolonged period of time. This was true even before the more draconian measures introduced in the Immigration and Asylum Act 1999. The prevailing environment of competition, performance review and value for money has had the effect of increasingly marginalising the most vulnerable groups in British society. In all but a few notable exceptions, the needs of asylum seekers have been inadequately addressed by either public or private sectors (Zetter and Pearl 1999a, 24-27). This has been due to a combination of institutional inertia and political sensitivity - both cock-up and conspiracy. The most recent legislative measures have further exacerbated the process of exclusion, generating additional hardship for an already overburdened group by extending uncertainty and increasing dependency. In reality, the rights and entitlements of refugees are little changed by the Immigration and Asylum Act 1999. They remain eligible to receive support and assistance in terms of both benefits and housing from the public sector. This is an important distinction from asylum seekers. Refugees are individuals or households whose status under the 1951 Geneva Convention has been approved by the UK government: that is, their 'well founded fear of persecution' has been accepted. They are likely to have either permanent or long-term status of residence in the UK and generally share in the usual rights of citizenship. (Duke, 1995, 12-18) Those with refugee status are eligible for assistance under the homelessness legislation and qualify for the housing register. To a large extent, such households have fewer institutional barriers to overcome than asylum seekers. Asylum seekers have no such clarity of outcome, for which they depend on the result of their pending application. While in this state of limbo, they are disqualified from access to employment, benefits or permanent housing, and are thus placed at the very margins of society. Indeed, at certain times within the mid-1990s, large numbers of single asylum seekers were actually destitute. (Joly, 1996, 121-128) The political reality behind the asylum legislation appears, therefore, to indicate a reliance on two cardinal principles above all other considerations: 1. the control and limitation of public expenditure, particularly personal benefits 2. the maintenance of an image of political toughness. (Robinson, 1985, 305- 330) It seems likely that excessive zeal in investigating applications and a
