Static Voltage Stability Analysis In Power Systems Engineering Essay

Static Voltage Stability Analysis In Power Systems Engineering Essay Voltage solidness, one of the key parts of intensity framework dependability, has been the principle explanation behind a large number of significant force framework power outage occurrences in the course of the most recent couple of decades. It is recognized generally that voltage soundness is and will stay a test in the 21st century, even prone to increment in significance. Hence a superior comprehension of voltage steadiness in power frameworks is vital for power engineers, who may partake in the arranging, structuring, and activity of present day power frameworks. This report discusses an important building postulation venture: Static Voltage Stability Analysis in Power Systems, which is done for 2 semesters from July 2009 to June 2010. The point of this proposition venture is to direct a progressively far reaching concentrate into the hypothesis of static voltage security, and explore another methodology for power stream investigation: 3-measurement P-Q-V bend. As a matter of first importance, the essential information on static voltage solidness is looked into, and examination on a basic force framework, outspread framework, is done including power stream study, P-V and Q-V bend investigation. In light of the 2-measurement P-V and Q-V plotting, the relationship of P, Q, and V is contemplated and another strategy for static voltage strength examination is attempted: P-Q-V bend. The second piece of this undertaking centers around the examination of WSCC three-generator-nine-transport framework. Recreation of the framework is brought through by methods for UWPFLOW and POWERWORLD. Direct force stream technique and continuation power stream strategy are applied and the most vulnerable transport is contemplated. To wrap things up, bends are gotten and results are examined. Watchwords: Static Voltage Stability; Radial System; Power Flow Method; Continuation Power Flow Method; P-V Curve; Q-V Curve; P-Q-V Curve.

Since the principal electric system in the United States was set up at the Pearl Street Station in New York City by Thomas Edison in 1882 [1], power frameworks have been encountering over 100 years advancement and improvement. These days, current force framework has created to be a complex interconnected system, which can be partitioned into four sections: Age Private and freely claimed generators produce the power that takes care of into high voltage frameworks. Transmission High voltage transmission networks transport power from producing units at different areas to dissemination frameworks which at last gracefully the heap. Conveyance Conveyance frameworks convey the force from neighborhood mass flexibly focuses to the shoppers administration entrance types of gear. Burdens Heaps of intensity frameworks are made out of mechanical, business, and private burden. Figure 1.1 Modern Power System [2] Force System Stability A force framework is supposed to be steady on the off chance that it has the property that it holds a condition of harmony under ordinary working conditions and recovers a satisfactory condition of balance in the wake of being exposed to an aggravation. Of all the perplexing marvels on power framework, power framework steadiness is the most unpredictable to comprehend and testing to investigate [3]. Harm to control framework security may make the framework power outage or breakdown just as other calamitous episodes, prompting huge social and financial misfortunes. Arrangement of Power System Stability In light of the frameworks various properties, organize structures and activity modes, the framework insecurity can carry on from multiple points of view. Likewise power framework soundness study is separated for the most part into three fields: edge security, recurrence solidness and voltage strength. The graph underneath shows outwardly the order of intensity framework solidness. Figure 1.2 Classification of Power System Stability History of Study on Power System Stability At first, precise solidness was right off the bat focused on and concentrated since power transmission ability had generally been constrained by either rotor edge (coordinated) strength or by warm stacking capacity. What's more, the power outage issues had been related with transient steadiness, which were lessened by quick short out clearing, ground-breaking excitation frameworks and differs extraordinary solidness controls [3]. At the end of the day, these days the hypothesis and strategies on rakish dependability are moderately increasingly complete. In the interim, concentrate on voltage security had been very moderate, which for the most part ascribed to two reasons: Occurrences brought about by voltage unsteadiness or voltage breakdown happened moderately late, not until which peopled focused on voltage shakiness issues. Comprehension of voltage precariousness was not all that significant as different sorts of unsteadiness issues in the good 'ol days. Changes of issues emerged during the examination on voltage strength, for example, load-based demonstrating, dynamic practices of various parts just as their connection, etc. Review of Power System Voltage Stability Voltage Instability Incidents in the World Force framework voltage soundness was right off the bat presented in 1940s, however neglected to draw people groups consideration until 1970s, since which voltage shakiness and breakdown had brought about a few significant framework disappointments or power outages all through the world, as recorded underneath [4, 5, 22]: August 22, 1970, Japan, 30 minutes; September 22, 1970, New York, a few hours; September 22, 1977, Jacksonville, Florida, few moments; December 19, 1978, France, 26 minutes; August 4, 1982, Northern Belgium, 4.5 minutes; September 2, November 26, December 28 30, 1982, Florida, 1-3 minutes; May 21, 1983, Northern California, 2 minutes; December 27, 1983, Sweden, 55 seconds; June 11, 1984, Northeastern USA, a few hours; May 17, 1985, South Florida, 4 seconds; April 1986, Winnipeg, Canada Nelson River HVDC joins, 1 second; May 20, 1986, England, 5 minutes; November 1986, SE Brazil, Paraguay, 2 seconds; January 12, 1987, Western France, 6-7 minutes; July 20, 1987, Illinoisand India, a few hours; July 23, 1987, Tokyo Japan, 20 minutes; August 22, 1987, Western Tennessee, 10 seconds; July 2, 1996, Western System Coordination Council (WSCC), Northern USA; August 1996, Malaysia; August 14, 2003, USA Canada; September 28, 2003, Italy. Progress of Study on Voltage Stability The enormous quantities of overall voltage breakdown occurrences caused it to turn into the focal point of universes regard for study voltage strength of intensity framework. During the 1982s investigating rundown of Electric Power Research Institute (EPRI) in USA, voltage strength was considered as the most huge issue. Throughout the most recent thirty years, and particularly over about the most recent twenty years, utility architects, specialists, and college analysts have seriously contemplated voltage steadiness. Several specialized papers have come about, alongside gatherings, conferences, and courses. Utilities have created handy investigation strategies, and are presently arranging and working force frameworks to forestall voltage flimsiness for valid unsettling influences [6]. Significance of Voltage Stability in Future In a not so distant, the worldwide quickly developing force utilization will require progressively concentrated utilization of accessible transmission offices, which implies an activity of intensity frameworks closer to their voltage solidness limits. The expanded utilization of existing transmission is made conceivable, to some extent, by receptive force pay [6]. Without a doubt, voltage security is and will stay a test in the 21st century, even liable to increment in significance. Along these lines a superior comprehension of voltage solidness in power frameworks is important for power engineers, who may take an interest in the arranging, structuring, and activity of current force frameworks. Theme Definition and Scope The subject of this venture is Static Voltage Stability Analysis in Power Systems, which for the most part centers around the accompanying: Diagram of the marvels of static voltage soundness; Investigation related with the marvels; Reasons why voltage breakdown occurs; Measures to improve static voltage strength. With regards to limitations on the reproduction, a three-generator-nine-transport case is utilized all through the entire venture while an ordinary two-transport (one-generator-one-load) case is utilized for the P-Q-V bend examination. Points and Objectives The fundamental target of this venture is to get a more extensive and more profound comprehension of static voltage steadiness in power frameworks, which can be decreased into sub-goals: To lead an increasingly extensive investigation into the hypothesis of static voltage solidness; To search for reasons why voltage breakdown occurs; To research another methodology for power stream examination: 3-measurement P-Q-V plotting; To propose appropriate proportions of improving static voltage dependability in power frameworks; To close age bearing and burden course for the examined power framework. Part 2 POWER SYSTEM VOLTAGE STABILITY Fundamental Concepts of Voltage Stability IEEE Definitions IEEE [7] gave a proper meaning of voltage soundness and relative ideas as given underneath: Voltage Stability: Voltage dependability is the capacity of a framework to keep up voltage with the goal that when load permission is expanded, loa

Question: Examine about the Accreditation Council of Pharmacy Education. Answer: Introdiuction: Panopticism is alluded as the social or hypothetical system which is named after Panopticon. The hypothesis was set up by French logician named Michel Foucault (Schaltegger Burritt, 2017). Panoticon gives clarification to the conditional research facility related with the power that can be changed or altered as the image of reconnaissance. It is commonly considered as the apparatus of disciplinary device for observation. For example, the case of Pannotion has expanded reconnaissance impact on the observation in the time of innovation and it is seen that observation have the intrigue of culture. The improvement in the perceptible information is given in the association and the people from the information mining devices (Lanen, 2016). This has brought about the improvement of reconnaissance of information that can address the method of observation that helps in calling attention to the removed exchange source by thinking about the algorithmic assembling. In the present part of the executives bookkeeping, Panopticism helps during the time spent administration bookkeeping as it helps in saving a record for each single exchange alongside the fundamental figures (Eldenburg et al., 2016). In this manner, Panopticism helsp in making sense of the mix-ups and blunders and suitable strides for amendment so as to ensure that the bookkeeping strategy stays valid. The elements of the executives bookkeeping are as per the following; Arranging: Planning as the elements of the executives bookkeeping alludes to the present moment and long haul utilization of plans to accomplish the ideal result. The elements of the executives bookkeeping is firmly connected with the arranging procedure (Ingersoll, 2015). This is on the grounds that it furnishes supervisors with the necessary data for dynamic and giving reports that gauge the effects of elective course of activities. Sorting out: Once the way toward getting sorted out is set up a hierarchical system and giving the obligations to individuals that are working in the association to accomplish the business objectives and items (Jones et al., 2017). The type of authoritative structures contrasts one business to another business. In this way, arranging requires clearness with respect to every director responsibility and authority lines. Dynamic: Decision making is considered as the methodology of choosing from the contradicting substitutes. Dynamic is acquired in the elements of the executives bookkeeping, for example, arranging, sorting out and controlling. The chief can't design without settling on choice and has the select from the contending goals and techniques for doing the chose targets. As expressed by (Dixon et al., 2018) keeping up routine and have become exceptionally mind boggling component in the present world since people are unavoidable to botches in the contemporary words. According to the Van Helen Rock Band agenda is essential apparatus of executing control. Agenda are useful in the usage and arrangement of control. As indicated by the musical crew, it is viewed as that Checklist is a significant instrument of executing control since this guarantees each individual that are occupied with the activity is better ready to comprehend the objectives and agreeing to the important methodology. As expressed by the musical gang they gain by utilizing agenda since check list as indicated by musical crew is profoundly viewed as exceptionally versatile. With the assistance of agenda, the musical crew is better ready to deal with the consistency of flexibly, inventories and they are commonly considered as the efficient component by including the required records in the midst of different things (Weygandt et al., 2015). Under this conditions agendas helps in keeping up fundamental records as well as required for essential achievement. The arrangement of interminable stock consistently refreshes the records for the little associations when it utilizes the crude materials or offers the items to the shoppers (Warren et al., 2015). Associations that utilizes the never-ending arrangement of stock must apply the arrangement of physical include of stock in to the everyday associations stock and think about the amount against the records of stock. The physical stock take in this framework would go about as the apparatus for researching in the inconsistencies of the stock record so as to decide the purposes behind ill-advised amounts. Extra time alludes to the expanded compensation for every hour which an hourly laborer is qualified for get when they put in more than the endorsed hour work every day or week (Handy Polimeni, 2017). The extra time installment that is paid to the specialist is considered as into the circuitous work cost and the equivalent is accounted into the overhead expenses. Costing alludes to the arrangement of bookkeeping where all the costs that are supported in executing the movement or accomplishing the goal are gathered, classified and checked. The rise of 1980 period purchased a concentrated rivalry over the world with expanded significance of over-burdens with the decrease in the immediate work (Greenberg Wilner, 2015). Likewise there was issues which was being confronted with the conventional arrangement of costing. The action based is considered as the exact and preferred over the conventional cost bookkeeping framework. The ABC techniques for cost framework is made when the costs of the business are higher and there are a few blended merchandise. Inaccuracy and slip-ups are viewed as unwanted because of the rates that is set by the market members. For the explanation that substantial and firm competition, an enormously reliable and right arrangement of cost the board is required. The conventional technique for cost bookkeeping utilizes the single overhead pool and it can't process the real expenses. The costs objects are allocated discretionarily the premise of machine hours and work (Edmonds et al., 2016). Then again, the ABC arrangement of costing incorporates the distinguishing proof of items parts or the work while the conventional cost bookkeeping subjectively amasses the costs, compensations and devaluation. The focused on costs which is made upon the exercises are registered through ABC costing. The ABC framework is viewed as gainful in light of the fact that it helps in smoothing out the course of dynamic and portrays the idea of organization turns as target arranged. The movement based costing technique helps in evaluating the exhibition and setting out the measures that help the directors to utilize the data with the end goal of relative investigation. Under the conventional costing frameworks, the business chooses the expense of creations following the creation of spending plans while under the ABC costing the estimation of the item is discovered dependent on the input of customer. The structure of movement based costing helps in deciding the organization whether to decrease or increment the action expenses to catch the eye of clients (Scott, 2015). The arrangement of cost helps in staying aware of the market members without doing without the amount and predominance of the items. The action based costing enables the organization in creating methodology, to long range plans and upper hand by setting center around the exercises. ABC arrangement of costing utilizes the cost distinguishing proof items which is chosen alongside the immediate costs that are related with the items. Regardless of the advantages there are sure contentions against the ABC costing framework in the cost assignment zones (Edmonds et al., 2016). With the accessibility of information there are a few costs that expects allotment to office and item assignment. This prompts event of costs that may not be now and again be respected conceivable. It tends to be expressed that customary costing framework isn't exact as the ABC framework. Conventional costing framework may likewise prompt considerable under valuation and over valuation. Absolute Cost of S1 Department (x) = Direct Center Cost of S1 + [20% * Total Cost of S2 (y) ] =, x = $20000 + (20% X y) b) Total Cost of S2 Department (y) = Direct Center Cost of S2 + [ 15% * Total Cost of S1 (x)] =, y = $25000 + (15% x) =, y= $25000 + [15% x ($20000 + 20%y)] =, y= $25000 + $3000 + 3%y =, y-0.03y = $28000 =, 0.97y = $28000 =, y = $28000/0.97 = $28868 x = $20000 + 20%y =, x = $20000 + (20% x $28868) =. x = $20000 + $5773 = $25773 Reference List: Dixon, G.

The Latest News . . . COLUMBIA UNIVERSITY - SIPA Admissions Blog I want to provide a quick update on a few things based on my work in the office the past few days.   I have been doing a bit of everything related to processing applications.   Here are a few personal notes on some of the tasks, under the theme, “I am always amazed . . . “ . . . at how dry my hands get when opening mail (and we get a lot). . . . at how extremely hot printer parts get.   Note to self:   When you are printing thousands of application documents and there is a paper jam, do not just randomly grab metal parts . . . touch them first to determine if they are white hot. . . . at how quickly our email in box fills up.   We get it close to zero, step away for a few minutes, and upon returning it is once again filled with messages. . . . at how many countries and schools are represented in our applicant pool each year.   Last year we received transcripts from close to 900 different colleges and universities from over 100 countries. Now to some information that really is important to you. First, I cannot emphasize enough that it is not important for an application to be marked as complete in our system the day after the deadline.   What is extremely important is that all of the required information is received in our office or uploaded to the server by the deadline.   Thus, it is completely normal for an application record to remain incomplete for two to three weeks after the deadline.   We have several thousand printed documents and mail to get through and Admission Committee meetings do not start until late January. Please do not let the fact that it will take us time to match and track everything concern you.   The date an application is completed in our office has no bearing upon an admission decision.  When your file has been forwarded to the Committee, you will receive an email from our office. Second, please remember that when you submit Part 2, transcripts and test scores are not automatically marked as received.   The personal statement and résumés are tracked as received immediately because we rarely have problems with the submission of these documents.   But as far as the transcripts and test scores, we need to make sure that the correct information is entered and legible.    Thus we will perform a manual check and then code them into the system as appropriate. Third, as much as we would like to respond to individual requests concerning the receipt of documents, this does not allow us to work efficiently and quickly.   Each person in the office has a job and we are set up as a sort of assembly line.   If one person in the system tries to go around the process and look for a specific document, it slows the process down and complicates matters. As much as I can understand emailing or calling to ask for the status of a specific document, we would much rather you wait to hear from us. I know the stress that accompanies admission deadlines.   As someone with a graduate degree I have been through the process as an applicant, and as an administrator I have been through close to fifteen years of deadlines.   We strive to provide the best service possible and by far the best thing you can do is follow this blog for updates on the process.   Rest assured that if we encounter a situation where a document is missing, we will work with applicants if we believe a good faith effort was made to supply the necessary document by our deadline date.   There is no need to send a document a second time to us unless we reach out to you first (we will do so by email if necessary). Thank you again for your attention . . . it is now time for me to find some hand lotion . . .

The Ever Growing Cosmetic Industry - 991 Words

According to an online article ‘12 Surprising Statistics About the Beauty Industry’ by Style Caster, one in three women admit to never leave the house without any makeup on (Irvine, 2013) This shows that the cosmetic industry caters to a large market of consumers who are willing to spend a major chunk of their income on self-adornment products and services. A report generated by YWCA USA (2008) indicated that a total of $7 billion is spent per year on cosmetics, which is 0.5% of the country’s total GDP. This essay aims to determine whether the ever growing cosmetic industry is affecting individuals in a positive or a negative manner physically and psychologically by studying various sources of information such as books, articles, reports and websites keeping a feminist’s approach towards the topic. Self-Adornment is not a recent practice. It dates all the way back to approximately 10 thousand years BCE with ancient Egyptians discovering healing properties in scented oils and gradually expanding into different cosmetic sectors then onwards. (Cosmetics info, 2015) Eventually, other counties adapted the adornment techniques from one another and had their own laws, trends and ideas of beauty in the course of time.

Is Lottery a Good Idea? Lottery is one of the best things that has ever happened to human kind especially those that dream high and but their dreams don’t come to life because they don’t have what it takes to make it happen. Lotteries are in various categories such as sweep stakes, scratch off, the Jackpot and even the green card lottery. The lottery that is being focused in this argument is the jackpot one.

The online gov. info library states that â€Å"Lotteries were frequently used in colonial-era America to finance public works projects such as paving streets, constructing wharves, even building churches. In the 18th century, lotteries were used to finance construction of buildings at Harvard and Yale.† This shows that lottery has been around for a long time. Today, most states have adopted lottery system especially the computerized ones like mega millions and Powerball due to the world advancing technologically. This is so because these states have seen the growth of income that come from lotto. Each state has rules and time frames in which a prize can be claimed. Some states allows people to be anonymous like Ohio while others don’t have that option. For example, in Indiana winners have 90 days before they claim their prize and their identity is revealed. In cases where the winning ticket isn’t claimed, the state will get back all the money that it contributed to the unclaimed jackpot. The money is distributed according to state rules. Even if the winner comes forward, every state that participates in lottery selling benefits from it. The state imposes both federal and state taxes on the winner. Winners have a choice to take a pay out as a lump sum or as an annuity. If the payment is lump sum, taxes are paid out at once and annually if the prize is taken as an annuity.

Farm Tools Free Essays

Agriculture has been in the limelight for several decades, it started in different countries across the globe each country in their own time. However, agriculture could not have been achieved without the use of farm tools and machinery. This farm equipment makes it easy for farm activities to be undertaken with an ease. We will write a custom essay sample on Farm Tools or any similar topic only for you Order Now Before the introduction of this equipment, agriculture was difficult and it was only done in small scale. Therefore, the agricultural produce which was produced as a result was only used for consumption purposes. However, with this machinery, there is a large production which is able to sustain consumption and also used for commercial purposes. The world depends largely on agricultural production therefore, farm tools should be embraced across the globe. First, combine harvester is one of the farm tools and it is one of the machines which combine several activities such as harvesting and threshing among others. This equipment was introduced in the year 1935 but it was first used for commercial purpose in the year 1939 (Kataoka). As the word combine suggests, combine harvester is used for several activities such as reaping. The second activity is threshing after the crops have been cut and collected the next activating is to separate the grain from corn. The other activity done by the combine harvester is grain separation, this activity is whereby the grain is separated from the husks. The last activity is cleaning whereby the grain is cleaned by blowing the chaff away. Second, the other farm tool is a mower, this tool is used for cutting grass. The tool is also known as a lawnmower. According to Kataoka, there are the different model of lawn mowers such as solar-powered lawn mower and this type is environmentally friendly. The other model of lawn mower is the automatic lawn mower, this type automatically detects the area of grass to be mowed and the height of grass as required. The other model is gas powered lawn mower and this model is not environmentally friendly since it emits gas into the environment. Lawnmowers are classified based on different factors such as the axis of rotation of the blades. For example, rotary lawn mower in which its axis is vertical and reel lawn mower in which its axis is horizontal. Third, a plough is another farm tool and it is used to till the land so as to aerate the soil for planting purposes. There are different types of ploughs depending on the function they perform. For example, furrow reversible plough which is useful in dry trashy stumpy and hard land condition. The tool is mounted directly on a tractor and it is hydraulically operated. It has two mouldboard ploughs mounted back to back whereby one rotates to the right and the other one to the left. The other type is the furrow press which is mounted behind the tractor. Chisel plough is the other type and this type is important in obtaining deep tillage with limited soil disruption. This type is used to reduce the impact of compaction and hardpan (Kataoka). Fourth, the harrow is another type of farm tool also known as a set of harrows. It is mostly used after ploughing has been done so as to break up the lumps and to achieve fine soil. This tool is mostly used when planting small size seeds like wheat, millet among others. It may also be used to remove weeds and cover seeds after planting (Kataoka). There are several types of harrows and they include power harrow in which the power from the tractor is used to drive the cultivators. The used set of harrows may be ineffective for the land since it makes fine soil, therefore, in case of heavy rains the soil may be washed away. Fifth, the other type of farm tools is the rotary tiller. As the name implies, this tool is used by rotating the tines and blades so as to cultivate the land. It is also known as a rototiller, rotary hoe, power tiller, rotary plough or rotavator. It is mounted on a tractor and it is operated by the power from the tractor. The rotary tiller can also be used by means of propelling itself. This equipment is also used after the plough has been used and the need for it is to break up the soil. It is mostly used in the gardens when planting vegetables and other crops. Sixth, the other tool is a broadcast seeder which is used to plant seeds in the farm. Has the name suggests this tool is used to plant seeds randomly in the farm. This activity is done by spreading the seeds without following a systematic way such as planting the seeds in a line. It can also be used to spread fertilizers commonly known as fertilizer spreader. The tool is also known as a broadcast spreader. The tool is mounted on a tractor normally a garden tractor so as to perform this act of sowing seeds or spreading fertilizers or lime. The small size of the broadcast spreader is handheld with a hopper while the slightly bigger ones are pushed with the spinning disk powered by gearing to the wheel. Seventh, the other tool equipment is seed drill, this tool is used for planting purposes. As opposed to broadcast seeder or broadcast spreader which spreads the seeds randomly, this tool plants seeds evenly and in systematic lines. The rows of these lines are easily controlled so as to achieve an even plantation. The depth of planting seeds is also even with the use of this machine. After the machine has sown the seeds it then covers them, therefore, protecting the seeds from the birds unlike in the case where they are randomly spread and the birds can easily pick them. The tool also saves time since it does all the work of sowing and covering unlike where the seeds are sown by randomly spreading then covered by using human labour (Kataoka). Eighth, the other tool is Centre irrigation and it is used for irrigation. The term irrigation is the application of water artificially to the soil in places where there is minimal rain or in the places with no rain at all. This tool is important in crop production because lands which could have been desolate due to lack of rain are converted into productive lands. This tool is also used to suppress weeds in the farm. Irrigation is also used to prevent soil consolidation, this is the process of changing the volume of the soil by preventing pressure. From the name Centre irrigation, it means that this tool is fixed in the farm therefore, water will be regulated as required by opening and closing when necessary. Ninth, hay tedder is another type of farm tools, this tool is used in haymaking. This tool came into use in the second half of the nineteenth century. After crops like wheat, rice, millet and other crops have been harvested the straws are left in the farm. These straws are useful in making hay for feeding livestock. Therefore, this tool is used in the process of making hay. It also uses moving forks so as to turn the hay and also to scatter the hay. The reason for this activity is to speed up the drying of hay by aerating them. This process also improves the colour and the aroma of hay. This tool is very important in speeding up of haymaking (Kataoka). Tenth, the sickle is another farm tool and it is used for cutting grass, hay among others. This tool is among the smallest farm tools and it is handheld as opposed to other tools which might be mounted on a tractor. This tool is also known as a reaping hook or a bagging hook. It came into existence in the Iron Age and since then it has evolved so much. It started with iron the latter it was made of steel. According to Kataoka, there are many types of sickle which include smooth and serrated blades. Both of these types are used either to cut grass or to harvest mature cereals such as wheat and millet. Causes and Effects of Agriculture in Ancient Egypt To start with, Egypt is known to be a dry land and agricultural practices require some amount of rainfall thus, there are causes and effects which came as a result of agriculture. Some of the causes which led to agriculture in Egypt is the fact that it is a dry region therefore, they used river Nile’s water for irrigation. With the irrigation system such as basin irrigation, agriculture in Egypt was birthed and therefore, there are effects which resulted from it. Some of these effects include increased productivity, productivity was increased as a result of agriculture through irrigation. The other effect is the reduction of poverty, due to agricultural productivity poverty was dealt with. Another effect of agriculture in Egypt was the creation of employment (Lewis). The significance of Pyramid in Ancient Egypt Egypt is well known for pyramids, these pyramids were built as tombs for the pharaohs and their queens. These pyramids were built in different shapes and sizes and they were about eight in number. One of them was built for Pharaoh Khufu and it was known as the great pyramid. Some of these pyramids are among the most magnificent man-made structures in history. These pyramids have a tremendous significant such as economic prosperity and stability. The pyramids had significant uses as far as the well-being of the king was concerned. The reason is, they were used to keep the king’s majesty intact even after his death. Egyptians did this activity because they believed that when the king died his spirit remained with his body thus, they were taking care of his spirit (Bà ¡rta). In conclusion, there are many farm tools and they are used for different purposes. These tools include plough which is used in cultivating the land. The other tool is a mower also known as a lawn mower which is used to cut grass. The other tool is broadcast seeder which is used to plant seed by broadcasting. It can also be used for fertilizer breading. The next tool is the seed drill which is used to plant seeds evenly and in the same depth. The other tool is Centre irrigation which is used to irrigate crops in dry areas and when there is an insufficient amount of rainfall. The other aspect is the causes and effects of agriculture in Egypt and it was caused by drought, therefore, using water from the river Nile for irrigation.

Strategic Analysis Cleveland Clinic free essay sample

The Veterans Administration (VA) should constantly be monitoring the current healthcare environment for trends and new treatment methods for post-traumatic stress disorders (PTSD). By monitoring the current trends treatment the VA is able to modify, change or continue the current treatment methods being used on past and current veterans. These trends allow the organization to scan for external environmental data to assist in treatment plans and recovery methods for veterans. This monitoring would confirm or disprove the possibility of various trend directions. These trends could be placed in various categories of economic, social/demographic and technological (Swayne, Duncan Ginter, 2008). Current outpatient treatment of PTSD by the VA has to be modified to treat a younger population of soldier and the VA has to monitor current trends in healthcare used by the private sector. The treatment methods have to be adjusted to not only treat PTSD but injuries as a result of combat. We will write a custom essay sample on Strategic Analysis Cleveland Clinic or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page This dual-use by a more technologically educated group of veterans makes monitoring by the VA a must in treatment. Also patients are choosing to use the VA for care due to the costs associated with receiving care from a private provider (Simpson, 2006). This would prevent VA patients from seeking emergency room care therefore adding to the ever increasing healthcare costs. Another area that requires an environmental analysis is providing care to the many diverse groups of veterans. The military is becoming one of the most diverse employers and the VA must explore various ways of getting more of these groups to seek care through the VA. Within the VA’s strategic vision and mission it addresses providing care to all veterans while demonstrating the value of VA care to the nation. (Fine, Demakis, 2003). An environmental analysis could provide useful data on trends in economic changes which address costs, demographic changes as well as competitive changes in healthcare. Although the Affordable Care Act does not affect veteran care, the stewardship of the VA healthcare system should be monitored for costs. The risks of not monitoring costs of care are budget cuts, poor technology and management of the veteran healthcare system. Although the budget is funded by the government, financial cuts do occur depending on the political party in office. These stakeholders want to see that there is a valid return on investment in the veteran healthcare system while providing quality care (Swayne, Duncan Ginter, 2008). Rural healthcare requires an analysis of environment to determine the factors that affect healthcare delivery to veterans. This analysis could address what types of changes would affect healthcare in rural areas in the future. One factor affecting care in rural areas is the recruitment of providers. What safety net would the agency have in place to address providing care to veterans in those rural areas? Nurse practitioners could be an option as well as offering residents better tuition assistance as many have acquired large amounts of educational debt (Simpson, 2006). Community based outpatient clinics provide a method of mitigating expenses that may be incurred by providing care in rural areas. An environmental analysis would provide some insight as to how the agency may provide care to veterans in those areas. This analysis may provide a look into resource allocation needs, what metrics are needed to measure effectiveness of the programs and how will quality be measured. The community based outpatient clinics would provide needed access to veteran who may be located in areas without a VA hospital (Liu, et al. , 2010). Conclusion Environmental analyses are vital to the strategic planning of the VA. Accessing the trends, forecasts, monitoring and scanning the environment will only mitigate risks and prepare the organization for changes in the future. Although the VA has a niche market the organization must address trends in healthcare insurance as this will affect veterans who can afford to make a choice of where they receive care. By analyzing this area the VA can maximize an opportunity to capture those veterans who are financially able to choose another healthcare provider. This may be done by offering those veterans a better option of quality healthcare in an environment they are familiar. References Fine, M. J. , Demakis, J. G. (2003).
