9 Famous Teacher Quotes

9 Famous Teacher Quotes What was unique about teachers who educated famous people such as Einstein, Abraham Lincoln, and the like? Were these teachers specially qualified to inspire their students to achieve fame and success? Or were these teachers just plain lucky to have exceptionally talented students? Do some teachers have the rare quality of turning dust into gold? The answer may not be easy to find. Good teachers are hard to find. Teaching institutes that offer the best facilities may attract the creme de la creme of teaching talent. However, a monetary incentive may not necessarily translate into good teaching. I have come across many selfless and good teachers working in NGOs and in charity organizations. These teachers are motivated simply by the joy of teaching. They take great pleasure in watching their students grow. They may not earn their share of fame and fortune, but they are truly wealthy in their benevolence. In this age of speedy information technology, you can access teachers from across the globe. Want to learn Spanish? Why not learn from a Spanish expert? Want to improve your dancing skills? There is no dearth of video tutorials.   A teachers job is never over even after the class is over. A teacher has to encourage each child to reach his or her potential. A teacher has to find ways to make learning fun, easy, and inspiring. Teachers have to explore various methods of instruction to enable higher learning. Tools merely assist the teacher. They cannot teach by themselves. Share these teacher quotes with your favorite teachers and bring a smile to their face.

Mesopotamian Civilizations and their technologies essays

Mesopotamian Civilizations and their technologies essays Many things that we have today were originally thought of back during the time of the ancient civilizations of Mesopotamia. Things like the government system, writing and technology underwent major change during that time. Mesopotamian civilizations flourished because of the discoveries and inventions that were made. There were great changes made in the government and justice system in Mesopotamian civilizations that allowed them to thrive. During the Babylonian civilization, King Hammurabi created a code of laws. He had scribes carve into tablets around 262 different laws. He was the one who created the theory that the punishment should fit the crime. These laws were categorized under many different headings, for example property and provided the society structure and order. Some civilizations, like Sumeria, were arranged into independent city-states. Rather than having one ruler with a vast empire, a city state would be comprised of a city and the land surrounding it, each with their own government. This way, it was more controlled as the government system didnt have to rule over a huge number of people. As wars became more frequent, the role of a king was added into government. This helped the civilizations to prosper because it gave the society a strong leader and a stable government. New inventions and improved technology helped everyday tasks become easier. The Sumerians most important invention was the wheel. This made the task of transporting things from one place to another much faster and easier. The wheel also improved wars, as people started to use wheeled chariots in their battles. Although it took a while to perfect the wheel, the invention of it changed the way that people worked and fought. Also, irrigation systems and canals were created. People could now control water a bit more and use it to their advantage. Crops were able to get a steady supply of water and therefore were much healthier and bountifu ...

Reflect on a Recent Change Management Project or Strategy Essay

Reflect on a Recent Change Management Project or Strategy - Essay Example Because of MediSys’ partnership with the local hospital, the health care organization requires specialized technology systems not commonly found in most independent care facilities. The change management strategy was to implement an EMR system, the electronic medical record, designed to change the methodology behind how MediSys communicates with the hospital, its patients, and external service providers. The goal was to implement a paperless health clinic and also improve the quality of patient-related information related to database storage and as it relates to patient referrals. This paper describes the change management project in detail, the systems and its function within the facility, and the barriers that were incurred during its launch and implementation phases. What is EMR? The electronic medical record provides a paperless environment in which clinical information is shared via electronic communications and transactions within an entire health network. It allows for information exchanges between hospitals, employers, patients, network payers, and even ambulatory clinics (Garets & Davis, 2006). Patient data is recorded in a database that can be easily accessed via various point-of-contact electronic service devices. Another reason for implementing EMR was to ensure less liability for the health care clinic related to errors. The Institute of Medicine offers that there are nearly a million injuries caused to patients and approximately 100,000 deaths each year due to dosing errors or adverse drug effects caused by health care worker neglect (Hook, Pearlstein, Samarth & Cusack, 2008). These errors cost the entire health care system over $2 billion yearly related to dispensing errors, transcribing errors, and medicinal administration. The change management goal was to remove such liabilities from MediSys and improve its reputation as a quality leader. The EMR provides nurses with pre-printed batch forms each month that provide resident information, their health identification number, special allergy concerns, dietary needs, and all medications previously and currently ordered for the patient (e-infomax.com, 2009). In addition, to improve service time and efficiency/productivity, a digital pen is included that allow the nursing and physician staff to carry the device that contains an infrared camera and digital processer so that they can read digitized words. At the end of the shift rounds, nurses and physicians simply dock the pen into a processing station and the information from the digital pen is transmitted to the appropriate external and internal units related to health care provision. When a physician or nursing signature is required related to patient care, the electronic pen immediately records this data and can be accessed within seconds. The implementation of the EMR system was to radically change the timeframe between when a signed document is retrieved, thus improving productivity, and also to avoid the lag times i n attempting to communicate when nurses or physicians are not readily available in the organization. The auto-generated reports can then be accessed and printed from a variety of stations set up at the organization and the system immediately identifies and prints a batch report when any document has not been properly signed, thus removing even more errors in processing paperwork. The Change Effort

Dalai Lama Research Paper Example | Topics and Well Written Essays - 2500 words

Dalai Lama - Research Paper Example About India he said that he was not satisfied with the present condition of India because though there is less violence but also there is too much corruption and exploitation. Dalai Lama directed Tibetan Government for certain periods between the 17th century and 1962. As per his view the institution of Dalai Lama may be abolished in the future. He won the Nobel Peace prize in 1989. Dalai Lama is also well known for his lifelong advocacy for the people of Tibet. He was selected at the age of 15 as the rebirth of 13th Dalai Lama and formally known as fourteenth Dalai Lama from the year 1950. The name of the fourteenth Dalai Lama name is Tenzin Gyatso remained the head of the state for the Central Tibetan Administration [Tibetan government in exile] until his retirement in 2011[March 14]. Tenzin Gyatso was born in the year 1935 [July, 6] in a small village of Taktser in northeastern Tibet. He was belonging to a Tibetan farming family. When he was at the age of three then his life was changed forever. He was identified by a search party of Buddhist officials. After that he was separated from his parents. He was transferred to a monastery for study where his elder brother was already studying in the same place and it reduced his pain of separation from his mother. In 1940 he was officially introduced as the spiritual leader of Tibet. His new name was assumed and that is Jamphel Ngawang Lobsang Yeshe Tenzin Gyatso. In November 1950, when he was only the age of 15, he was introduced as Tibet’s temporal leader in a ceremony in Lhasa. After that he spent most of the next decade trying to avoid a full-scale military takeover of Tibet by Chinese forces. The holiness of Dalai Lama began from his monastic education at the age of six. Five major and five minor subjects were included in the curriculum of study. Those subjects are Sanskrit,

Poor Reproductive Fitness of Sperm in Aging Males

Poor Reproductive Fitness of Sperm in Aging Males Deterioration of germline DNA found to produce low quality offspring in aged male houbara bustards. A study in houbara bustards, an African bird species gives insight on what is happening with aging men. The scientists suggest that the decline in hatching success observed is caused by senescent decline of both male and female gametes. On the other hand, the development of chicks within the egg appear to be influenced solely by maternal aging which can be explained by reduction in older females’ abilities to provision their eggs. The researchers then monitored the artificial insemination of houbara bustards ranging in age from 1 to 23, recorded the egg hatching success as well as the growth of resulting chicks. Their results found that eggs produced from inseminating older females with ejaculate from older males have lower hatching success as compared to eggs of parents at peak age. The scientists suggest that the decrease in hatching success observed is caused by senescent decline of both male and female gametes. Of the eggs that did hatch, it was discovered that the mass of chicks at hatching were heaviest in chicks born to young mothers, suggesting that the development of chicks within the egg appear to be influenced solely by maternal aging. This can be explained by reduction in older females’ abilities to provision their eggs. Additionally, it was found that chicks born to young fathers had the best overall growth within the first month of life than those born to older fathers. The reason for this is that since males only contribute their DNA to offspring, the growth of the How Reproductively Fit is the Sperm of Older Males? A study in houbara bustards, an African bird species gives insight on the production of low quality offspring in aging men. Gametes are reproductive cells such as ovum or sperm, containing the genetic material required to form a new organism. This genetic material is essential in determining the quality of offspring produced. According to the paper by Brian Preston and his colleagues in Nature Communications, gametes from animals of advanced years undergo degradation by a process called senescence. Senescence is a gradual decline of function and can occur by two mechanisms. The first is the decline in the performance of their spermatogenic machinery such that the sperm has difficulty in carrying out its function. The second mechanism involves the build-up of genetic mutations within the germline of gametes, resulting in the degradation of the DNA carried within. These mechanisms lead to a reduction in both the viability and quality of offspring produced. To determine whether male aging has influence on reproductive fitness, Brian Preston and his colleagues examined 10 years’ worth of data regarding the post insemination success of male houbara bustards part of a captive breeding programme. To begin with, female bustards were inseminated with ejaculates collected from males. The male and female bustards involved in this study ranged from 1 to 23 years of age. Eggs produced were collected and the hatching success recorded. The researchers found that eggs produced from inseminating older females with ejaculate from older males have lower hatching success as compared to eggs of parents at peak age, suggesting that this is caused by senescent decline of both male and female gametes. Furthermore, of the eggs that did hatch, it was discovered that the mass of chicks at hatching were heavier in chicks born to young fathers compared to older fathers. Additionally, a measure of overall growth within the first month of life showed that chicks born to old fathers had the worst overall growth. The scientists reasoned that the cause for growth patterns observed in chicks born to old fathers confirms that the dominant mechanism of senescence in the bird species is mutation-based aging of germline DNA. This is because, since males only contribute their DNA to offspring, the growth of the chicks is inhibited. Eggs produced were collected for incubation and hatched chicks were hand-reared so as to avoid any confounding variables. The researchers monitored the artificial insemination of houbara bustards ranging from 1 to 23 years old, recorded the egg hatching success as well as the growth of resulting chicks. Their results found that eggs produced from inseminating older females with ejaculate from older males have lower hatching success as compared to eggs of parents at peak age, suggesting that this is caused by senescent decline of both male and female gametes. Of the eggs that did hatch, it was discovered that the mass of chicks at hatching were heaviest in chicks born to young fathers. Furthermore, it was found that chicks born to old fathers had the worst overall growth within the first month of life than those born to younger fathers. The scientists suggest that the development of chicks within the egg appears to be influenced solely by maternal aging. This can be explained by reduction in older females’ abilities to provide their eggs with nutrients. On the other hand, the researchers reasoned that the cause for growth patterns observed in chicks born to old fathers confirms that the dominant mechanism of senescence in the bird species is mutation-based aging of germline DNA. This is because, since males only contribute their DNA to offspring, the growth of the chicks is inhibited. According to a recent study by Brian Preston and his colleagues in Nature Communications, gametes (ovum or sperm) from animals of advanced years undergo degradation by a process called senescence. Senescence is a gradual decline of function and occurs by two mechanisms. The first involves the decline of the spermatogenic machinery performance while the second mechanism involves the build-up of genetic mutations within the germline DNA of gametes. To determine whether male aging has influence on reproductive fitness, the researchers examined 10 years’ worth of data on the post insemination success of male houbara bustards aged between 1 to 23 years that were part of a captive breeding programme. First, female bustards were inseminated with the male ejaculates collected so that gametes are the only influencing factor on offspring quality. The eggs produced from older parents were seen to have lower hatching success when compared to eggs of peak age parents. Of the eggs that did hatch, researchers observed that the lightest chicks at hatching were a result of maternal aging. Alternatively, a measure of overall growth within the first month after hatching revealed that chicks born to older fathers had the worst overall growth. In other words, as males age, their ability to produce offspring that are viable and of high quality diminishes. These findings lead scientists to conclude that the dominant mechanism of senescence in the bird species is mutation-based aging of germline DNA. Additionally, it seems that the decline in offspring development linked to paternal aging is similar in scale to that linked to maternal aging. Interestingly, when findings were compared with that of human studies similar patterns were observed, deepening concern for the recent trend of delayed parenthood in both sexes. In future, Brian Preston and his colleagues wish to be able to identify and quantify the reproductive cost associated with male aging in a long-lived species. In their most recent work, published in Nature Communications, they found that, not only did males appear less able to produce offspring successfully as they aged, they also appeared to produce offspring that were of intrinsically lower quality. Perhaps most surprisingly, these declines in offspring quality were of a similar size to those resulting from maternal aging. Patterns observed in humans are in line with the findings in houbara bustards and their interpretation, with paternal aging being linked to adverse reproductive outcomes, a number of genetic diseases, and some mental disorders. The evidence is beginning to accumulate that delaying parenthood until later life can potentially have negative consequences for the children of both older men and women.

Lean Thinking and Accounting Issues Essay

Womack and Jones (1990 1-6) famously used the term â€Å"lean† on Toyota Motors Corporation referred to Toyota Production System (TPS) in the book The Machine That Changed the World. In the year 1990, the two authors toured various companies in North America, Europe and Japan advocating for companies to convert their mass production practices to lean practices, through presentation of ideas on how to do the same. A movement of management thinkers then emerged which clearly advocates for organizations to identify and if possible completely cut the huge wastes found in mass production. Lean movement supporters opine that forecasts are always wrong, and therefore they advocate managers to work to reduce order-to-delivery time. They also say that there are no more powerful tools available to companies for eliminating waste and creating value than lean ideas, according to Marchwinski and Shook (2003 21-23). Lean Manufacturing; Toyota Motors Corporation Case Toyota Motors Corporation is the most notable successful company in implementation of lean thinking. As a matter of fact, the motor vehicle maker is often used a reference in studying the operations and triumphs of the Lean Thinking management concept. The company introduced the concept of lean manufacturing in its now famous production system, the TPS (Toyota Production System) in the 1980s. The introduction of the concept of lean manufacturing was a move against the grain of the day as the trend of the day by companies was mass production, as Womack and Jones (1996 82-83) mentioned in their book. Toyota Motors Corp became very successful in the wake of implementation of this shake-up in its processes as to become the largest vehicle manufacturer in the world. One important section where lean thinking was applied by TPS is in processing method. A batch-and-queue system was converted into to a continuous flow, which had the effect of doubling labor productivity, cut 90% through output time, reduced injuries and cut errors by fifty percent. The introducing a lean manufacturing strategy was brought about by the need to eliminate the huge waste that the company’s chief executive Ohno (1988 17-31) had observed in the production processes of the company, which he pointed out as to be in the processes of Inventory, waiting, transportation, overproduction, over-processing, motion and over-processing. Lean Principles; In lean thinking, the first step to understand what lean thinking is and the resources-together with the activities- that are necessary in creation of that value. Everything else becomes waste once value is identified. The job of determining what value is and what activities add value should be done at a high level, because nobody would want to consider what he or she does as waste. If any breakthroughs are to be made in lean thinking the ability to see waste should be strong. Something is waste if it does not add value directly. A Toyota Executive, Taiichi Ohno, identified and described the following seven as the types of wastes that are found in any process: Inventory, waiting, transportation, overproduction, over-processing, motion and over-processing. Some authors have added goods and services that do not meet customer’s needs and underutilization of people. There are five lean principles; Value: This principle deals with the value that an organization offers to its clients. It is the complete package of services and products that a business enterprise makes use of to serve its customers and penetrate the market from the angle of view of the clients. Only the ultimate customer can define value (Womack and Jones 1996 218). In line with accounting practices, for instance target costing approach, the price the client is willing to pay is a reflection of the value he derives from the product/service. In turn, the value translates to the service and product costs the enterprise must achieve for the clients as well as the stakeholders to be satisfied. Value stream: It reckons that the processes of an enterprise crate customer-driven performance as well as excellence. The structures of conventional departmental controls contravene lean thinking as it was it posited by Poppendieck (2002 1-2). A business enterprise must comprehend, control and manage its operations through the value steams or processes of the enterprise. In manufacturing companies, there are three top-level value streams; the design and problem solve value stream, the value stream of the product, and the value stream that encompasses the enterprise’s controls and transactions. These value streams more often than not extend to cover entities outside the enterprise such as suppliers, partner firms and the customers. In general terms, all the actions that are required to bring a product to the customer are what are referred to as the stream values. Flow: The ideas connected to â€Å"flow† have their origins in the Toyota Production System. The lean movement is of the stance that anything that interferes with the flow of services as well as goods out to the customer through the value stream should be designated as waste. The value stream must be studied by an enterprise in order to achieve smooth, uninterrupted flow from production materials to delivered services and products. In this way, an enterprise ruthlessly, eliminates waste from its processes.

Greed and the Seven Deadly Sins

Greed is one of the most deadly sins and there are three forms greed. Greed is the most committed sin in the world we see everyday a person wanting more money, power, or goods. This sin is one of the most commonly depicted sin in the world the make movie, TV shows, and songs about this sin. Shows like American Greed describe people that commit this sin almost everyday people like Henry Jones, Albert Gonzalez, and Scott Rothstein these people committed this sin everyday of their life to so many people and hurt them so much that they are now in a hole they will never climb out of in their lifetime. Greed for Power This type of greed if for power over something or someone in the upmost way of any form of ruling. The kings of a country would be a prime example of this kind of greed; King George III would be a great example of this type of greed. He was king during the American Revolution; he fought so hard to keep control over the American colonies that drove him insane. The American people fought back to gain the power to govern their own country. We see in history that almost every country in history fought for power to govern themselves. In this since of greed everyone in history has the greed of power everyone wants the power that no one ever keeps. Greed for Money This form of greed is the most commonly seen through history; every period in history you will see a person that has this greed of money in many forms. Bill Gates is a prime example for this type of greed; he in his life would buy a program and then would take this program and turn it in to what we know as Window DOS and then in to the Windows operating systems. This idea that Bill had made him millions; he turned a deal he made for $50,000 in to millions making him one of the riches people on earth. But, still he wants more money to fund his lifestyle that he is so use to living. Greed for Goods This type of greed is a need to own goods to feel powerful. China as a country is a prime example; they feel if they provide the world with cheap items they can run the world’s economy. China provides around 65 percent of the items in the United States stores in this day and age, they run most of our economy as is it stands. China can make these items for a cheaper rate then we can make the item in this country so we go and buy these items from China instead of making it our self. The US doing this is fueling China greed for power over goods. This is Greed Greed alone is one of the most committed sin in this world; we do it almost every day in some since of the word. The three types of greed make no difference when you say whether or not you committed the sin of greed or not. Whether you are power hunger, money hunger or in the need for greed of goods, you still are a greedy person. Greed is greed whether you want to say it or not America is a very greedy country. This world is a greedy world we live in, everywhere you go all you see is greed.

The Meaning of Nani in Japanese

The Meaning of 'Nani' in Japanese The word nani  Ã¤ ½â€¢ (㠁 ªÃ£  «) in Japanese means what. And depending on the situation, you might, instead, use  nan (㠁 ªÃ£â€šâ€œ). Which term you use depends on the context, in particular, whether you are speaking or writing formally or informally. The sentences below are listed first in a transliteration of the Japanese phrase or sentence, followed by the spelling in Japanese characters- using  kanji,  hiragana, or  katakana  as appropriate- followed by the translation in English. Where indicated, click on the link to bring up a sound file and hear how to correctly pronounce the word or sentence in Japanese. Using Nani or Nan in a Sentence Nani is the more formal and polite term to use when asking a question, as in: Nani  wo  suru  tsumori  desu ka? (㠁 ªÃ£  « ã‚’ 㠁™ã‚‹ 㠁 ¤Ã£â€šâ€šÃ£â€šÅ  㠁 §Ã£ â„¢ 㠁‹)   What do you intend to do? or What are you planning to do? In more casual situations it would  be  fine to use nan. As a general rule,  if the word following what begins with a syllable from the t, n, and d groups, use nan, as in: Nandeshou? (㠁 ªÃ£â€šâ€œÃ£  §Ã£ â€"ょ㠁†) What do you want? More on Using Nan vs. Nani Nan is used before  particles.  A particle is a word that shows the relationship of a word, phrase, or clause  to the rest of the sentence.  Particles are added to the end of sentences to  express the speaker  or writers  emotions, such as doubt, emphasis, caution, hesitation, wonder, or admiration. You might use  nan   with a phrase such as /㠁 ®, /㠁 § (which means of the and is pronounced no de)  and verb da/desu (打㠁 §Ã£ â„¢ ), meaning it is hitting or it is striking. Nani is used before: /㠁‹ (meaning or and pronounced as ka)  and /㠁 « (meaning into a and pronounced as ni). Be careful when you use nan because, for example, if you use  nan  before ka  (/㠁‹), which means or, it would sound like the word nanka  (㠁 ªÃ£â€šâ€œÃ£ â€¹), which means things like. Another example would be if you were to use  nan with  ni (/㠁 «), it would be nanni  (㠁 ªÃ£â€šâ€œÃ£  «), meaning why, but this sounds very much like nannimo  (㠁 ªÃ£â€šâ€œÃ£  «Ã£â€šâ€š), which translates as nothing at all. Using Nani or Nan in Context You might use  nani  or  nan  in a restaurant. Depending on whether you are at a formal business luncheon or a casual eatery, you might use either of these terms. For example, at fast food eatery you might say: Osusume wa nan desu ka.  (㠁Šå‹ §Ã£â€š Ã£  ¯Ã¤ ½â€¢Ã£  §Ã£ â„¢Ã£ â€¹) What do you recommend?Are wa nan desu ka. (㠁‚ã‚Å'㠁 ¯Ã¤ ½â€¢Ã£  §Ã£ â„¢Ã£ â€¹Ã£â‚¬â€š) What is that?   If you are at a more formal eatery, but you dont know what to order, you might ask a fellow diner: Nani ga oishii desu ka. (ä ½â€¢Ã£ Å'㠁Šã â€žÃ£ â€"㠁„㠁 §Ã£ â„¢Ã£ â€¹Ã£â‚¬â€š) What is good? If you are traveling on a train and need to ask for help from a stranger or train conductor, that would be considered a more formal situation in Japan. Thus, you would use  nani  and might say: Tsugi  wa  nani  eki  desu ka.  (æ ¬ ¡Ã£  ¯Ã¤ ½â€¢Ã© §â€¦Ã£  §Ã£ â„¢Ã£ â€¹Ã£â‚¬â€š) What is the next station? However, if you are traveling with a friend, you might use   the informal  nan, as in: Nan-ji  ni  demasu  ka.  (ä ½â€¢Ã¦â„¢â€šÃ£  «Ã¥â€¡ ºÃ£  ¾Ã£ â„¢Ã£ â€¹Ã£â‚¬â€š)   What time does it leave?

Filtration Definition and Processes (Chemistry)

Filtration Definition and Processes (Chemistry) Filtration is a process used to separate solids from liquids or gases using a filter medium that allows the fluid to pass through but not the solid. The term filtration applies whether the filter is mechanical, biological, or physical. The fluid that passes through the filter is called the filtrate. The filter medium may be a surface filter, which is a solid that traps solid particles, or a depth filter, which is a bed of material that traps the solid. Filtration is typically an imperfect process. Some fluid remains on the feed side of the filter or embedded in the filter media and some small solid particulates find their way through the filter. As a chemistry and engineering technique, there is always some lost product, whether its the liquid or solid being collected. Examples of Filtration While filtration is an important separation technique in a laboratory, its also common in everyday life. Brewing coffee involves passing hot water through the ground coffee and a filter. The liquid coffee is the filtrate. Steeping tea is much the same, whether you use a tea bag (paper filter) or tea ball (usually, a metal filter).The kidneys are an example of a biological filter. Blood is filtered by the glomerulus. Essential molecules are reabsorbed back into the blood.Air conditioners and many vacuum cleaners use HEPA filters to remove dust and pollen from the air.Many aquariums use filters containing fibers that capture particulates.Belt filters recover precious metals during mining.Water in an aquifer is relatively pure because it has been filtered through sand and permeable rock in the ground. Filtration Methods There are different types of filtration. Which method is used depends largely on whether the solid is a particulate (suspended) or dissolved in the fluid. General Filtration: The most basic form of filtration is using gravity to filter a mixture. The mixture is poured from above onto a filter medium  (e.g., filter paper) and gravity pulls the liquid down. The solid is left on the filter, while the liquid flows below it.Vacuum Filtration: A  Bà ¼chner flask and hose are used to create a vacuum to suck the fluid through the filter (usually with the aid of gravity). This greatly speeds the separation and can be used to dry the solid. A related technique uses a pump to form a pressure difference on both sides of the filter. Pump filters do not need to be vertical because gravity is not the source of the pressure difference on the sides of the filter.Cold Filtration: Cold filtration is used to quickly cool a solution, prompting the formation of small crystals. This is a method used when the solid is initially dissolved. A common method is to place the container with the solution in an ice bath prior to filtration.Hot Filtration: In hot filtration, the solution, filter, and funnel are heated to minimize crystal formation during filtration. Stemless funnels are useful because there is less surface area for crystal growth. This method is used when crystals would clog the funnel or prevent crystallization of the second component in a mixture. Sometimes filter aids are used to improve flow through a filter. Examples of filter aids are silica, diatomaceous earth, perlite, and cellulose. Filter aids may be placed on the filter prior to filtration or mixed with the liquid. The aids can help prevent the filter from clogging and can increase the porosity of the cake or feed into the filter. Filtration vs. Sieving A related separation technique is sieving. Sieving refers to use of a single mesh or perforated layer to retain large particles​ while allowing the passage of smaller ones. In contrast, during filtration, the filter is a lattice or has multiple layers. Fluids follow channels in the medium to pass through a filter. Alternatives to Filtration There are more effective separation methods than filtration for some applications. For example, for very small samples in which its important to collect the filtrate, the filter medium may soak up too much of the fluid. In other cases, too much of the solid can become trapped in the filter medium. Two other processes that can be used to separate solids from fluids are decantation and centrifugation. Centrifugation involves spinning a sample, which forces the heavier solid to the bottom of a container.

Case Study - Essay Example These prior meetings have been based upon the need to update the stakeholders on the progress of the project on far simpler issues. As a result, these past meetings have been much smoother, but this time, serious challenges that touch on the project scope will arise. These include; an extension of the project deadline by up to four weeks; the proposal for implementation of a formal change-order process and managing the client’s resistance to change. Timeline delay Although, as a software project manager my mantra is keeping an eye on time, and budget, sometimes the two issues may require adjustment due to unexpected issues that stem from the implementation process (Wysocki, 2010). Owing to the fact that most of such projects are not completed within the timeline as agreed upon at the beginning of the project implementation process, this one is not an exception. This project is expected to delay by between one to four weeks due to changes in the requirements of the system. More specifically, we have spent more time that we expected, waiting for new resources. The need to expand the functionality of technology in order to allow for a seamless way to monitor the various human resources functions have extended past the original scope. The client’s systems need â€Å"gold plating,† which is expected to consume more time that was expected. An extension of time to allow for successful completion of the project and ensure that the deliverables are realized is therefore imperative. It is important to note that, even though the stakeholders came together to develop all their requirements before starting the project, system requirements have changed, making the project to wait for the shipments of new product supplies. Change-order Process Owing to the variation of costs and the timeline for completing the project, change-order processes will help the stakeholders to make the necessary modifications to the original project plan and scope as a trade-of f for the realization of quality project deliverables (Wysocki, 2010). The original agreement spelt out the structure of the network systems and the expected final result. However, due to the changes in the system requirements, it is important for the client to give in to extra funding in order to keep an eye on quality, as effective measures have been put in place to guard against project creep. More specifically, the stakeholders need to adjust to the new timeline for the completion of the project by at most four weeks so as to satisfy all the stakeholders’ new expectations. The client will be required to sign the change order form detailing the modified plan, including the system services, hardware and software, and designs as a way of formalizing a mutually binding agreement. Resistance to change This project had a clear scope within which to work, hence should be respected. However, due to the fact that changes that arise during the implementation process are inevitable, all the stakeholders should work in tandem to respond to the changes reasonably and more appropriately to ensure that the final deliverables are achieved (Wysocki, 2010). The existence of new stakeholders is the major risk facing the project, even as some flexible stakeholders are striving not to compromise quality for limiting costs and the amount of time that is required to successfully complete the

The Concept of Open Kitchen Design Essay Example | Topics and Well Written Essays - 1000 words

The Concept of Open Kitchen Design - Essay Example Among the range of advancements however, of particular interest is the concept of Open Kitchen Design. This concept has been attractive to many restaurateurs for not only its entertaining factor, but also because customers can be able to see exactly how food is being prepared and as such they are more likely to prefer it as opposed to situations where they cannot tell what is being put into their plate. This increases the level of hygiene that is involved and lowers the chances of occurrence of food poisoning. So what exactly are the views of customers on the Open Kitchen design? This paper analyzes the work of Alonso and O’neill, Exploring Consumers’ Images of Open Restaurant Kitchen Design, where a research has been conducted on this area so as to find out what the customers really want and as such give them exactly that in this era where customer satisfaction is the recipe to the success of every business. The Background Research has revealed that consumers in the Un ited States have a preference for food prepared outside the home setting, (Alonso et al, 2). On average, a consumer will take five meals in a week in a restaurant as opposed to home. On the same note, it has been noted that consumers obviously attach a lot of importance to the hygiene and safety of the food they eat though this is something that most restaurants ignore. Further, hygiene and cleanliness of food is closely related to the design of the kitchen that a restaurant decides to have thus the design of a kitchen can play a big role in ensuring food safety, reduced number of accidents as well as efficiency in operations. This idea in itself will attract customers as it gives them the satisfaction that they are having a meal that is properly prepared by merely looking at the physical setting of the kitchen. An attractive kitchen design will also encourage employees to carry out their duties with utmost care in providing high quality food. Reports indicate that more and more res taurants are embracing the open kitchen design and it has been responsible for booming business for small enterprises despite meager materials through research, (Alonso et al, 4). Thus the work of Alonso and O’neill aims at bringing more light on the subject. Methodology Used Consumer data was obtained through questionnaires distributed within duration of four months at a university in the United States from individuals attending a baseball sport during the season. The reasons for choosing a university for the collection of this data was the convenience of collecting data from a large number of individuals composed of different groups in terms of gender and age and then making comparisons. The success of the research was also facilitated by the fact that the researchers also belonged to the university in question and therefore it was easy for the respondents to identify themselves with them. The content and design of the questionnaire was prepared according to the little avai lable data from research previously conducted on the image of consumers on the idea of Open Kitchen Design. The research also took into consideration the demographic factors of the respondents, experience and frequency of consumers, type of restaurant visited, factors affecting consumers’ tastes and preferences and to what extent the design of the restaurant affected their choices. Instructions on how to go about the research questions were also provided. The potential respondents were
