The Farm :: Descriptive Farms Essays Papers

The Farm Flat Rock Farm was a hardscrabble anachronism in the 1950s. The dirt roads of Kansas, in those days, were littered with similar testimonies; relics of another time, passed down by the pioneers who carved them from the prairie. That it survived at all was a testament to the resourcefulness and tenacity of those that had scratched a subsistence from it during the dust bowl and great depression. Once the fulfillment of life-long dreams, farms like this one were being rendered obsolete by the emerging consumer society of post-war America. To the uninitiated there was nothing unique or extraordinary about this particular farm, except perhaps for the telltale signs of its certain obsolescence. The harness hanging from the tack room wall, the idle team of aging horses milling in the corral, the bucket at the cistern pump and the absence of electric lines all betrayed the homestead's lack of modernization and its inevitable future. Like thousands of others, it would be bought out and combined with a larger, more modern operation when death or bankruptcy hastened its demise. The passing of such a small and unremarkable homestead on the Kansas prairie would not be noticed nor long remembered -- yet it is. To a small boy growing up in the inner city, there was no place more wondrous or exciting to visit than that small farmstead somewhere northeast of Emporia. It was a vibrant place, alive with the sights and sounds of nature and bustling with important work that mattered. Work whose value and purpose was easily recognized by a child. Work connected to the land and animals in some grand collaboration with the universe. There were people there too who were glad when you came to visit. Patient people who cared, and who took the time to listen as well as teach. People who understood the value of a small child's efforts to help with the important work of the farm and encouraged those efforts. There always seemed to be a humming in the background that permeated everything there. A current, perhaps, that ran through it all and kept the people, land, and animals in sync with some universal pattern. I couldn't actually hear it, but if I sat very still on the rocks by the well pump, on a warm spring afternoon, and closed my eyes, I could feel it. The warmth of the rock beneath me, the sun reaching out to touch my skin, the breeze on my cheek -- all were connected -- as I was, with the sounds of the insects and animals around me.

Bacterial Concentration and Diversity

The objective of this particular paper was to study the results that were extracted when bacterial communities were formed. These bacterial communities were formed through the process of the reproducibility of small volume of repeat sampling from replicate bioreactors with stabilized continuous-flow chicken cecal bacterial communities. The results referring to the bacterial concentration and diversity were then analyzed by phenotypic, biochemical and ribotype analysis. To grow bacteria a stable environment is the most essential requirement this stable and a constant environment is known as steady-state conditions.This allows bacterial cultures to be obtained in a reproducible manner for batch consistency. The cultural efficacy was determined by taking an assumption that the aliquot taken from the cultures were identical and therefore did not overall affect the results to be determined by the particular experiment (bacterial culture). Mixed samples of avian cecal material were used to establish replicate bioreactor cultures. Repetitive samplings of the planktonic components were done to determine if all aliquots had the like bacterial contents within the same bioreactor.Consistency was seen during this repetitive sampling process but changes were seen in the specific composition of the resulting communities that initiated from one supply of cecal assortment. These are the basis on which the whole experiment and the methodology are based on. METHODOLOGY: †¢ Bioreactor and Sampling Design: The cecal contents were extracted from 150 birds (chicken) and then thoroughly mixed under sterile anaerobic conditions. Three replicate bioreactors (Bioflo ® 110 Fermentor/Bioreactor, New Brunswick Scientific Co, Inc., Edison, NJ) were used. The steady-state conditions were maintained by keeping the cultures under continuous-flow conditions at a flow rate of 0. 8 ml/min and also flushed with carbon dioxide that was free of any oxygen. For the first 48 hours the pH of the bioreactor was maintained to a stable 6. 2  ± 0. 3. Then for 3 weeks the cultures were allowed to reach equilibrium the planktonic component was sampled 11 times during this 3 weeks period. After this period 1ml aliquots were collected for analysis. i. e. pH measurement , bacterial isolation etc.†¢ Bacterial Isolation and Preliminary Identification: The material obtained from the bioreactor was sampled and some of the bacterial cultures obtained were quantified by growth of a 10? l aliquot on selective media in triplicate. The triplicate had a 5% sheep blood and was used to determine hemolytic reactions and for the recovery and the enumeration of the aerobic microbial species. The identification and the isolation of the aerobic bacteria was done by streaking the 10  µl aliquots onto TS-blood agar , Brilliant Green Agar, BGA; Becton Dickinson, Sparks, MD), CHROMagar E.coli and Orientation, MacConkey, mEnterococcus, and Rogosa plates. These plates were then incubated for 24 hours at thirty seven degrees. Likewise anaerobic bacteria were isolated too but the streaking was done onto Brucella-blood agar, Phenylethyl alcohol agar (Becton Dickinson, Sparks, MD), Veillonella, and BBE plates. The plates were then incubated anaerobically for 48-72hours at the same temperature. These bacteria were also tested for aero tolerance. †¢ Enumeration:The total aerobic and anaerobic population levels were enumerated by serial dilation onto TS-blood agar, MacConkey, mEnterococcus agars or Brucella-blood agar plates, respectively. †¢ Ribotype Characterization: Isolates from the bacterial lawns were collected and analyzed by using RiboPrinter ® Microbial Characterization System following the manufacturer's instruction using lytic enzymes. Endonuclease EcoRI was used to cleave the DNA and gel electrophoresis was used to separate the fragments and analysis was done using a modern hybridization blotting technique.The DNA hybridized was labeled rRNA operon prob de rived from Escherichia coli, and the bands were detected by chemiluminescence. The image formed was captured and transferred to the RMCS database and data were normalized to a standard marker set. The images were compared with the 6448 EcoRI riboprint patterns in the DuPont database and a 900 EcoRI riboprint pattern custom in-house database (USDA, ARS, College Station, TX). †¢ Data Analysis: For each set of combined cecal material the above mentioned 3 replicate bioreactor were established.These were then analyzed for enumeration and characterization (eleven per bioreactor). The statistics were represented in tabular form. Commercially available software was used to analyze and calculate data. Differences in cfu/ml were compared among the replicate bioreactors. MAIN RESULT: The collecting of bacteria cultures or any other organism is greatly affected by the sample size and the frequency of organisms being sampled in a particular environment. Some of the processes or the methods described above also have limitations due to different constraints that govern their working e.g. enumeration. Enumeration of bacteria is affected by many factors including individual species growth rates, fitness of each competing species etc. therefore the bacteria produced or grown in a selective media maybe less productive when exposed to competition from many other species in a non-selective media culture. The probability of collection is greatly affected by the spatial distribution of organisms. As a rule the sampling requirement must increase as the degree of unit aggregation increases.Enumeration is also affected by aggregation and may account for some of the variation reported in the bacterial quantification. Therefore considerations should be given to the sampling size when using aliquots for inoculation from cultures with known aggregating species. An important thing to mention here that whatever the sampling technique is used there are also certain limitations associate d with sampling. It is not only quite difficult to harvest all species comprehensively but our present technological inability also creates a hindrance because we are unable to artificially culture all bacterial species.It was also seen that the efficiency of detection of pathogenic bacteria is affected by dilution i. e. a lower efficiency of detection was achieved where the prevalence of the target bacteria was diluted. A threshold quantity of specific bacteria maybe required for the proper mix. Adjustments in population density, adhesion and diversity which occur during culturing period greatly affects this observation. CONCLUSION: The aim of this study or experiment was to determine reproducibility of small volume repeat sampling with the help of a bioreactor.Basically bacterial concentration and diversity were the two important factors that were being concentrated these two quantities were analyzed within stabalised continuous-flow chicken cecal bacterial communities initiated b y replicate aliquots taken from thoroughly mixed samples. Pooled cecal material was created from layer chicks to establish the bioreactors. After a steady-state was reached the plankton components were sampled repetitively for three weeks and was then characterized by phenotypic, biochemical and ribotype analysis.No notable differences were found in the bacterial concentrations that came from the same bioreactor. Differences were found in bioreactors initiated from the same stock material. BIBLIOGRAPHY 1.

Amazon vs Wallmart

Amazon vs Wallm Amazon vs. Walmart Alexandra Tikhonkikh Professor N. Kentish Metropolitan College of New York The case study Amazon vs. Walmart is illustrated several concepts, which was described in the chapter. One of them is a sales Revenue Model where companies get revenue by selling goods, information, or services to customers. Like Amazon. com which sells books, music, and other products. Another one is e-tailer model.It is close to the typical bricks-and-mortar storefront, except that customers only need to connect to the Internet to check their items and place an order. The value scheme of e-tailers is to provide convenient, low-cost shopping 24/7, offering large assortments and consumer choice. Some e-tailers, such as Walmart. com, indicated to as â€Å"bricks-and-clicks,† are divisions of existing physical stores and have the same products. Others, however, exist only in the virtual world, without any ties to physical locations like Amazon. com. Before we going to a nalyze Amazon and Walmart. om using the value chain and competitive forces models, we suppose to describe these two concepts. Business Value Chain Model include: 1) views firms as series of activities that add value to products or services, 2) highlights activities, 3) primary activities vs. secondary activities, 4) regulate how information systems could advance customer and supplier disintermediation at each step of development, 5) utilize benchmarking. Michael Porter’s competitive forces model provides general view of firm, its competitors, and environment.It also substitutes products and services. The model include customers and suppliers, moreover, it contains traditional competitors and new market entrants. Besides, five competitive forces shape fate of firm. Amazon. com started as on line bookseller, but has expended into a wide variety of media, electronics, and other general merchandise categories in support of its business strategy. Amazon’s value chain includ es primary and support activities. Primary activities are very important for business, because those needed to manufacture a product or services for the end users.These activities typically include: 1) service: basically meant by after-sales support like user training, install applications, customer support and etc. , 2) operations: manufacturing the product, 3) inbound logistics: receiving goods from supplier and storing those goods, 4) outbound logistics: sending goods to wholesalers, retailers or directly to the end customer, 5) marketing and sales: product needed to be sold to the end customer, to understand customer requirements and also to promote goods.Support activities help to facilitate or assist the primary activities of producing product. There are four category: 1) Procurement: purchasing raw material and other items used in operations, 2) Human Resource Management : recruiting, hiring, firing, training, developing, compensating, 3) Technological Development : research and development, process automation, software, hardware, equipment, etc. , 4) Infrastructure : may include accounting, legal, finance, planning, public affairs, government relations, quality assurance and general management.As to Amazon’s competitive advantages from a value chain there are several strategies of development like strong technological infrastructure with a single platform, high investments in technology development for example Kindle, the best leverage digital products, great product forecasting system, print on demand, constantly imploring suggestions on new products, easy and fast payment system, 24/7 operations, free returns within 30 days. Amazon. com competes with product specific retailers; online marketplace and mass merchandise retailers.This creates an environment of intense competition and requires Amazon. com to differentiate itself uniquely based on the competitor. Let’s try to consider a Wal-Mart position from the competitive model as well. C ompetition among rivals is fairly weak. The market is crowded but Wal-Mart has the lowest costs, prices, profits, and market share. The warning of substitute products is also weak. Wal-Mart exerts a great deal of effort in making sure they are innovative and meeting customer requests. The bargaining power of suppliers is weak as well. For most producers, Wal-Mart would be their largest account.The bargaining power of buyers is also weak. There is a very broad base of customers and a meaningful demand for low prices. The threat of new entrants is weak. Wal-Mart has a scale of operation that is very important, it would take years, maybe even decades, for a new company to be on the same level. Even prominent companies today would have really difficult time matching the costs and prices Wal-Mart provides. A more sophisticated analysis of Wal-Mart’s internal value chain shows that Wal-Mart is hold in esteem to technology and was the ? rst merchant, which uses bar codes.It also use s satellite connections to communicate with all its stores. Moreover, Wal-Mart has integrated its POS, inventory-control, RFID, and other logistical technologies to haste product delivery, improve security and decrease costs. Besides It has developed regional obtaining centers in addition to its legendary center in Bentonville, Arkansas. Wal-Mart even has one in Shenzhen, China. Merchants set up satellite of? ces next door to the most suitable procurement center. Because Wal-Mart is a retailer, not a manufacturer, its external value chain is extremely simple.It deals with a variety of merchants and sells to customers. But the secret to discovering what makes Wal-Mart successful in studying its internal value chain. We should mentioned Walmart's competitive advantages from a value chain perspective. First of all it is a distribution capabilities: well-organized distribution, leadership of Walmart’s own distribution centers and â€Å"inside-out† location strategy. Second , is partnership relationship with merchants: integrates suppliers via IT ; treats them well in terms of pricing, they are more business partners than â€Å"value takers†.Third, is advanced data mining: dynamic group and usage of customer buying behavior report. Forth, workforce culture and EDPL: customer-oriented workforce interested through substantial monetary contribution and belief in Walmart’s culture. And that’s not hard consider the fact that Walmart is almost 50 years old. Wal-Mart’s business strategy is to provide â€Å"Every day Lower Prices† or EDPL for all its products and services. Their organization, company culture, and supply chain management all support and emphasize this business strategy.Also, Wal-Mart use strategy of managing costs which include: budgeting payroll cost, saving on business travel cost, investing in technology, eliminating unnecessary costs. Another strategy that we have to mention is a strategy of managing growt h, which consists of location and acquisition. And the last one called strategy of managing people resources. Every company that wants to be successful supposes to pay attention to this strategy as well. Internal promotions, employee motivating and external recruitment are the main components of this strategy.By implementing these three important strategies successfully, Wal-Mart has become from a single store to the biggest retailer in the United States and the biggest company in the world. The cost management strategy of Wal-Mart was created an operational model with the lowest cost which was increased the ratio of profit on the financial reports. Products found in Wal-Mart stores are not considered to be a high-end, luxury, or fashion oriented. Because their strategy is being a low price leader. Wal-Mart aims to provide a wide variety of products under one location for a low price.Wal-Mart stores also carry their own private labels that compete on price with national brands. More over, the growth management strategy had hauled Wal-Mart into the right direction of investment and expanded radically around the distribution center. However, the people management strategy motivates all employees to work more efficiency and generates a great workplace environment which full of self-improvement, competition, and respects. It also provides a chance for people to build-up experience from the low-rank position to the high-rank position.Consequently, strong management in these three strategies had transformed Wal-Mart into the biggest company in the world with the highest number of workers worldwide and had also provided benefits to millions of people around the world by transferring avoidable cost into low-cost products. Now we are going to consider the management, organization and technology factors that have contributed to the success of Amazon. Firs of all, Amazon is convenient and easy of use. It has a large selection of different items, unlimited virtual shelf sp ace and wholesale relations, so you could find any product for acceptable price.The service is high performance, which could be proven by high speed and reliability. Customers are kept informed well about new products and the system that provides shipping makes the process fast. Also, Amazon use innovative technology, which contribute development and support of all system in whole. For short time Amazon. com became a well-known brand with cross promotion, high advertising, co-branding and publisher relations. Amazon. com is also famous for its large community where customer and author reviews post. It has a great gift policy for customer like bookmarks, notepads, cups, etc.Amazon arranges promotions where customers could collaborate with famous authors. The site has a large customer database with personalization pages, which contain extensive customer profiles. It also has recommendation pages, which help other readers make a right choice. Amazon has a high trust for their users bec ause of guarantees and return policy. Great customer service is also promote trust of users because of superior service reps, easy search, email confirmation, extended service, extensive subject index, ability to order before publication. By the way Amazon has good cost structure.Besides low prices it has fast, reliable and inexpensive shipping. Amazon and Wal-Mart using e-commerce is a fascinating combination of business models and new information technologies. Wal-Mart’s impressive growth in such a short time and perhaps the most important factor in it’s rise was their exploiting of the dominance of e-business, e-procurement, and the modification of internal processes to maximize it’s benefits. In compare with others companies, Wal-Mart transformed supply chain management by using a sales revenue model where customer requests satisfy by wise variety of goods.Inventory control is perfect improved and purchasing trends are available to sellers, whom nowadays mus t be able to respond as quickly as possible to the needs of millions of customers. To decentralize the procurement was a great business decision for Wal-Mart, that helped simplify the process for employees in every store immediately order the applicable stock automatically, which is require prompt turnout of product from the suppliers. This fast replenishment system, attached with perfect purchasing forecasting, helps Wal-Mart reduce overall costs.Wal-Mart’s power as a giant in business has helped in establishing new standards for B2B e-commerce. Wal-Mart’s approach of cutting costs at all costs resulted in them deploying EDI over the Internet to eliminate the costly VAN altogether. EDI over the Internet (EDI-INT) uses a new standard called AS2, a communication protocol that attempts to make EDI communications over the Internet both secure and reliable. By mandating their suppliers to use AS2, Wal-Mart leads the way in creating a demand for a new generation of EDI, and in turn drives the whole world of e-business advancing.Amazon’s e-commerce business model Amazon started as a store that focused primarily on books and music. It quickly expanded to other sectors and now sells products in nearly every segment – apparel, home improvement, groceries. In addition, Amazon has expanded from a Business-to-Consumer (B2C) only store to a mixed model with its corporate account functionality that focuses on business customers. Added to the mix, is the Amazon marketplace – Amazon's answer to eBay, which allows merchants to list their products and customers to purchase from merchants while using Amazon's e-commerce platform.As a provider of e-Commerce software to mid-market, we use Amazon as a reference for the features it has on the web store. Some of these features not easily found on other sites include the ‘1-Click Ordering’, ‘Customer Viewing’, ‘Recently Viewed Products’, ‘Keyword Auto-fill ’ on the product search, ‘Your Personalized Store’, and ‘Items to Consider’. While some of these features are relatively easy to implement e. g. ‘1-click Ordering’, others are not so easy and demand an advanced platform. But selling goods isn't the only way to make money with Amazon. com.The Web site's affiliate program is one of the most famous on the Web. Through Amazon's   Associate Program , anyone with a Web site can post a link to Amazon. com and earn some money. The associate can also take advantage of Amazon Web Services , which is the program that lets people use Amazon's benefits for their own purposes. The Amazon Web Services API (application programming interface) lets developers access the Amazon technology infrastructure to build their own applications for their own Web sites. All product sales generated by those Web sites have to go through Amazon. om, and the associate gets a small commission on each sale. On the flip s ide, Amazon seems to not have kept up with the Web 2. 0 and Web 3. 0 user interface improvements and for most part still incorporates Web 1. 0 technology which means – you still need a mouse click to view a product as opposed to being able to see product details with a mouse roll-over. Amazon could use a make-over to make for a brighter shopping experience. For my opinion Amazon’s e-commerce business model is stronger than Wal-Mart’s e-commerce business model because E-commerce is Amazon’s core mission and environment.Amazon started with a store that was properly feature-rich for its time and has gone on to strengthen that foundation. Today, it probably defenses as the leader in terms of the richness of its e-Commerce features, product breadth, personalized recommendations and depth of content available across e-commerce sites. However, there is a need for Amazon to offer a simplified and trendier shopping experience as an alternative which many other sit es now offer. I don't think Wal-Mart will replace Amazon any time soon, if ever, but it gives them a good shot of increasing their overall Web penetration.Amazon's value proposition until now has been a broad assortment. This enables Walmart to compete with other companies with big assortments. I would prefer to make my internet purchases at Wal-Mart because this company has a great experience and long term history. Wal-Mart exists almost 50 years, Amazon is a brand new, successful but still doesn’t have that experience that Wal-Mart does. Some reviewers have actually built their following on Amazon. com with good quality reviews.

Abiotic And Biotic Characteristics Environmental Sciences Essay

San Francisco Bay has maintained a brilliant organic structure of H2O and usage to prolong the economic system of Western United States and San Francisco Estuary in Bay in is of great importance because through this a big figure of H2O run outing becomes possible. It ‘s Estuary from where fresh H2O meets to sea H2O. There are many pollutants that we face in our day-to-day life e.g. soil, deposits, oil, lubricating oil, fertilizes pesticides chemicals etc. the H2O running from the land transporting these pollutants to underground and finally this range to the Estuary of san Francisco. These pollutants when range in river and sea H2O can foul the whole H2O and turn out harmful for aquatic life as it can be cause injury for wetland animals like fish, and can turn out really unsafe for other home grounds of H2O. It can destruct the aquatic system and can be major menaces for the life being populating under H2O. As San Francisco Estuary considered as a really of import part and has much economic importance so for bar of pollution and maintain safe this part from other different factors Restoration and preservation is used.Abiotic and biotic features of the San Francisco EstuaryMany of environmental factors affect the abiotic and biotic features of the San Francisco Estuary these include both abiotic and biotic features. These factors effects the life in Estuary in great extends. Inanimate factors are called abiotic factors which include concentration of O and foods, salt of H2O and sum of sunlight. As these factors have the major impact on the life in estuary. All life factors that affect the estuary are called biotic factors. That includes manufacturers ‘ consumers and marauders as manufacturers are of basic importance for consumers. Consumers rely on manufacturers and marauders rely on consumers. So these are depend on one another to keep the balance of estuary,Population growing in the San Francisco Bay country affected the estuaryIncreasing tendency of population in San Francisco Bay country affected the estuary as increasing tendency of population cause a haste in urban every bit good as on small town countries. More the people are utilizing the resorts more the waste is making and much usage of H2O and H2O waste from its usage create pollution as much of the contaminated H2O is drained through the belowground ways to Estuary that is a great menace for the marine life. More over in recent old ages 40,000 metric dozenss of pollutants enter the Bay yearly from agribusiness and urban overflow. Rivers, atmospheric radioactive dust, municipal sewerage intervention workss, industrial installations, natural and unreal eroding, illegal clearance, dredging and dredged stuff disposal, marine vas discharges, inadvertent spills, and landfill ooze are besides doing jobs every bit good. ( 1 )Habitat break in the San Francisco Estuary been increased by human behaviourEstuaries is of great importance for us as these are used for nutrient, trade and for shelter and in this instance Sans Francisco Bay has great importance as it is used as seaport for many ships of this parts. There are big figure of workss and animate beings found in Estuaries and the most of population of San Francisco Bay depend on these marine lives for their nutrient. But due to the pollution spreading by addition in population cause injury to these workss and animate beings. This pollution can do harm to the lives of these workss and animate beings found in estuaries. Heavy burden of silt, rubbish, and deposits by eroding and chemical taint cause can turn out to be harmful for these workss and animate beings and can make asphyxiation for them. Due to increase in irrigation or by doing more dikes by the people can do jobs as more the salty H2O will travel upriver as comparison to normal everyday that can do destructive effect for species populating in the H2O. The most of import impact of human population in estuaries habitat in San Francisco is the development of estuaries. Peoples are seeking to acquire spread out the country of estuaries for development intent as they are rather interested to utilize the land for lodging and concern intent as they want to desire to use the part of estuaries for industrial development. Economically estuaries are really good for these intents but this can caused the doomed of big figure of home ground found in these estuaries. So it is harmful for the H2O species and go the cause of Habitat break in the San Francisco Estuary. Aquatic Nuisance Species ( ANS ) is transporting the being across America and around the Earth. This phenomena is increasing that cause injury to native fish and wild life in different ways as it disturb the full nutrient web and cause jobs for human life activity every bit good e.g. interrupting the H2O bringing and set uping the agribusiness every bit good.Conservation being used to advance and keep the biodiversity of workss and animate beings in the San Francisco EstuaryBiodiversity of workss and animate beings means scope of organisms including different workss and animate beings, present in ecological system. It is really of import to advance and keep the biodiversity of workss and animate beings to acquire the broad assortment of being that will be good and usage to carry through human demands. San Francisco Estuary is of great importance for the home ground of this part as they get of import benefits from them so to salvage this and to last from the loss of species found in t hese estuaries it is really of import to properly mange and develop the system to get away from the loss of marine species as good. Estuary of San Francisco Bay is of great importance in all over the universe. To procure it from un exceeding phenomena and widen the productive usage of it The San Francisco Estuary Partnership ( SFEP ) is playing really of import function as they have used different attacks to cut down the impact of Aquatic Nuisance Species ( ANS ) . They have start to see species direction program I order to retrieve the species of Estuary from harmful effects. Fish in the estuary demand O to last so the estuary where there is increased pollution that ‘s doing lost of marine life, Submerged aquatic flora ( SAV ) produces O for fish external respiration and to cut down the pollution. The Sans Francisco Bay preservation and development committee ( 2 ) prepared a program to do and implement the policies for the development of Bay and to use the maximal benefits from them. The Sans Francisco Bay program is created and implemented by this committee in 1968. The of import conversation of this program was related to shore line and coastal countries to use it to their maximal potency. Conservation of fish and other aquatic being is most significantly depend on the O that is provided to these beings, fresh H2O, handiness of nutrient for these beings, sufficient country of genteelness and quality of H2O. If these factors are organized in proper manner so it became possible to keep and better the biodiversity of workss and animate beings of Sans Francisco estuary. The Sans Francisco Bay preservation and development committee has taken of import stairss to reconstruct these constituents in order to guarantee the benefits for the future coevals of these fish, and other wild life of estuary. This committee besides provides recommendations in Bayland Ecosystem habitat Goal Report about the diverseness of home ground O heighten the assortment of aquatic workss and carnal species. The Baylands Ecosystem habitat Goal Report works to supply the of import information about the types, sum, and distribution of wetlands and its home grounds that are needed to keep a healthy eco system.DecisionSan Francisco Estuary is of great importance as this is a passage zone between watershed and ocean and economically this system has great importance for that part that ‘s the ground of Restoration of this estuary. Many action programs has made for the development, publicity and care of these Estuary and many more action programs are expected in close hereafter for farther development of this ecosystem.

Discourse: Ellen Lupton’s Deconstructivist Theory Essay

Key concepts from Ellen Lupton’s A Post-Mortem on Deconstruction? * Deconstruction is part of a broader field of criticism known as â€Å"post-structuralism,† whose theorist have included Jacques Derrida, Roland Barthes, Michel Foucault, Jean Baudrillard, among others. Each of these writers has looked at modes of representation – from alphabetic writing to photojournalism – as culturally powerful technologies that transform and construct â€Å"reality†. The phrase â€Å"deconstruction† quickly became a cliche in design journalism, where it usually has described a style featuring fragmented shapes, extreme angles, and aggressively asymmetrical arrangements. This collection of formal devices was easily transferred from architecture to graphic design, where it named existing tendencies and catalyzed new ones. The labels â€Å"deconstructivism,† â€Å"deconstructionism,† and just plain â€Å"decon† have served to blanket the differences between a broad range of design practices and an equally broad range of theoretical ideas. Rather than viewing it as a style, you can view deconstructivism as a process – an act of questioning. In Derrida’s original theory, deconstruction asks a question: how does representation inhabit reality? How does the external appearance of a thing get inside its internal essence? How does the surface get under the skin? For example, the Western tradition has tended to value the internal mind as the sacred source of soul and intellect, while denouncing the body as an earthly, mechanical shell. Countering this view is the understanding that the conditions of bodily experience temper the way we think and act. A parallel question for graphic design is this: how does visual from get inside the â€Å"content† of writing? How has typography refused to be a passive, transparent vessel for written texts, developing as a system with its own structures and devices? * The Western philosophical tradition has denigrated writing as an inferior, dead copy of the living, spoken word, when we speak, we draw on our inner consciousness, but when we write, our words are inert and abstract. The written word loses its connection to our inner selves. Language is set adrift. * It has recently become unfashionable to compare language and design. In the fields of architecture and products, the paradigm of language is losing its luster as a theoretical model – we no longer think of buildings, tea pots, for fax machines as â€Å"communication† cultural messages, in the manner of post-Modern classicism or product semantics. For the design fields, â€Å"deconstruction† has been reduced to the name of a historical period rather than an ongoing way of approaching design. Derrida made a similar point in 1994, saying that deconstruction will never be over, because it describes a way of thinking about language that has always existed. For graphic design, deconstruction isn’t dead, either, because it’s not a style or movement, but a way of asking questions through our work. Critical form-making will always be part of design practice, whatever theoret ical tools one might use to identify it. Apollinaire’s Il Pleut is a perfect example of the juxtaposition of language and design – of typography and content. Like the other structural games calligrammes are often referred to, Il Pleut uses typography as an active picture rather than a passive frame, demonstrating only the beginning of the possibilities available for manipulating type to reflect language. Often graphic design can reveal cultural myths by using familiar symbols and styles in new ways, and Apollinaire does exactly that in this futurist, poetic, and exciting way. Marinetti, another Futurist-classified poet, was a master in deconstruction — letting the words themselves build imagery both literally and figuratively; the letterforms and sentences themselves becoming the building blocks of his compositions. This 1913 work by Marinetti, Words of Liberty, is a perfect example of the theory of metalanguage, proposed by Roland Barthes. In his work, Elements of Semiology, he advanced the concept of the metalanguage — a systematized way of talking about concepts like meaning and grammar beyond the constraints of a traditional (first-order) language; in a metalanguage, symbols replace words and phrases. Insofar as one metalanguage is required for one explanation of first-order language, another may be required, so metalanguages may actually replace first-order languages. Barthes exposes how this structuralist system is regressive; orders of language rely upon a metalanguage by which it is explained, and therefore deconstruction itself is in danger of becoming a metalanguage, thus exposing all languages and discourse to scrutiny. A work of design can be called â€Å"deconstruction† when it exposes and transforms the established rules of writing, interrupting the sacred â€Å"inside† of content with the profane â€Å"outside† of form. Weingart is the perfect example of this, using not only letterforms themselves but also nonobjective elements within his composition to distort the typographic content. Yet, the link between language and typography is so close that typography is, essentially, the frontier between languages and objects; languages and images. Typography turns language into a visible, tangible artifact, and in the process transforms it irrevocably. While researching the link between the â€Å"inside† and â€Å"outside† form of content, George Orwell seemed to hold very similar views in his The Politics of English Language, speaking not of the link between typography and language but instead the written and spoken versions of English itself. Modern English, especially written English, is full of bad habits which spread by imitation and which can be avoided if one is willing to take the necessary trouble; and what trouble does this necessarily include? Protecting one’s writing from staleness of imagery, and of course lack of precision. Both are marked by vague writing or perhaps, in some cases, sheer incompetence of modern English prose, as well as the use of dying metaphors. He concludes for us that verbal false limbs and pretentious diction are the downfall for our mangled language, and we, the ambitious struggling writers of the world, can unite against its seemingly inevitable destruction. But let us look closer at Orwell’s reasoning for a moment; that if thought corrupts language than surely language can also corrupt thought. Although written nearly 60 years before our time, he shares this ideal with a modern behemoth of writing – Stephen King. King has already imparted a great secret to us about the nature of writing – that ideas come from nowhere, and that vocabulary is one of the first steps toward a novel which actually functions as it should. One should not begin writing from the abstract, trying to dictate with impressive words or alliterative sentences; one should have an idea in mind and then set about trying to convey that idea to an audience. Vague writing only begets vague understanding, which is not the vehicle in which your novel should be riding. I personally feel that this is a powerful parallel to language and typography — that the designer should have in mind what exactly they are trying to communicate before beginning their design, instead of taking text copy and moving it around, trying to design without a firm message at hand. This eventually will end in a vague, incomprehensible and garbled communication, one which has no place in today’s world; unless of course you happen to be a self-proclaimed Dada-ist.

A Game of Thrones Chapter Nine

Tyrion Somewhere in the great stone maze of Winterfell, a wolf howled. The sound hung over the castle like a flag of mourning. Tyrion Lannister looked up from his books and shivered, though the library was snug and warm. Something about the howling of a wolf took a man right out of his here and now and left him in a dark forest of the mind, running naked before the pack. When the direwolf howled again, Tyrion shut the heavy leatherbound cover on the book he was reading, a hundred-year-old discourse on the changing of the seasons by a long-dead maester. He covered a yawn with the back of his hand. His reading lamp was flickering, its oil all but gone, as dawn light leaked through the high windows. He had been at it all night, but that was nothing new. Tyrion Lannister was not much a one for sleeping. His legs were stiff and sore as he eased down off the bench. He massaged some life back into them and limped heavily to the table where the septon was snoring softly, his head pillowed on an open book in front of him. Tyrion glanced at the title. A life of the Grand Maester Aethelmure, no wonder. â€Å"Chayle,† he said softly. The young man jerked up, blinking, confused, the crystal of his order swinging wildly on its silver chain. â€Å"I'm off to break my fast. See that you return the books to the shelves. Be gentle with the Valyrian scrolls, the parchment is very dry. Ayrmidon's Engines of War is quite rare, and yours is the only complete copy I've ever seen.† Chayle gaped at him, still half-asleep. Patiently, Tyrion repeated his instructions, then clapped the septon on the shoulder and left him to his tasks. Outside, Tyrion swallowed a lungful of the cold morning air and began his laborious descent of the steep stone steps that corkscrewed around the exterior of the library tower. It was slow going; the steps were cut high and narrow, while his legs were short and twisted. The rising sun had not yet cleared the walls of Winterfell, but the men were already hard at it in the yard below. Sandor Clegane's rasping voice drifted up to him. â€Å"The boy is a long time dying. I wish he would be quicker about it.† Tyrion glanced down and saw the Hound standing with young Joffrey as squires swarmed around them. â€Å"At least he dies quietly,† the prince replied. â€Å"It's the wolf that makes the noise. I could scarce sleep last night.† Clegane cast a long shadow across the hard-packed earth as his squire lowered the black helm over his head. â€Å"I could silence the creature, if it please you,† he said through his open visor. His boy placed a longsword in his hand. He tested the weight of it, slicing at the cold morning air. Behind him, the yard rang to the clangor of steel on steel. The notion seemed to delight the prince. â€Å"Send a dog to kill a dog!† he exclaimed. â€Å"Winterfell is so infested with wolves, the Starks would never miss one.† Tyrion hopped off the last step onto the yard. â€Å"I beg to differ, nephew,† he said. â€Å"The Starks can count past six. Unlike some princes I might name.† Joffrey had the grace at least to blush. â€Å"A voice from nowhere,† Sandor said. He peered through his helm, looking this way and that. â€Å"Spirits of the air!† The prince laughed, as he always laughed when his bodyguard did this mummer's farce. Tyrion was used to it. â€Å"Down here.† The tall man peered down at the ground, and pretended to notice him. â€Å"The little lord Tyrion,† he said. â€Å"My pardons. I did not see you standing there.† â€Å"I am in no mood for your insolence today.† Tyrion turned to his nephew. â€Å"Joffrey, it is past time you called on Lord Eddard and his lady, to offer them your comfort.† Joffrey looked as petulant as only a boy prince can look. â€Å"What good will my comfort do them?† â€Å"None,† Tyrion said. â€Å"Yet it is expected of you. Your absence has been noted.† â€Å"The Stark boy is nothing to me,† Joffrey said. â€Å"I cannot abide the wailing of women.† Tyrion Lannister reached up and slapped his nephew hard across the face. The boy's cheek began to redden. â€Å"One word,† Tyrion said, â€Å"and I will hit you again.† â€Å"I'm going to tell Mother!† Joffrey exclaimed. Tyrion hit him again. Now both cheeks flamed. â€Å"You tell your mother,† Tyrion told him. â€Å"But first you get yourself to Lord and Lady Stark, and you fall to your knees in front of them, and you tell them how very sorry you are, and that you are at their service if there is the slightest thing you can do for them or theirs in this desperate hour, and that all your prayers go with them. Do you understand? Do you?† The boy looked as though he was going to cry. Instead, he managed a weak nod. Then he turned and fled headlong from the yard, holding his cheek. Tyrion watched him run. A shadow fell across his face. He turned to find Clegane looming overhead like a cliff. His soot-dark armor seemed to blot out the sun. He had lowered the visor on his helm. It was fashioned in the likeness of a snarling black hound, fearsome to behold, but Tyrion had always thought it a great improvement over Clegane's hideously burned face. â€Å"The prince will remember that, little lord,† the Hound warned him. The helm turned his laugh into a hollow rumble. â€Å"I pray he does,† Tyrion Lannister replied. â€Å"If he forgets, be a good dog and remind him.† He glanced around the courtyard. â€Å"Do you know where I might find my brother?† â€Å"Breaking fast with the queen.† â€Å"Ah,† Tyrion said. He gave Sandor Clegane a perfunctory nod and walked away as briskly as his stunted legs would carry him, whistling. He pitied the first knight to try the Hound today. The man did have a temper. A cold, cheerless meal had been laid out in the morning room of the Guest House. Jaime sat at table with Cersei and the children, talking in low, hushed voices. â€Å"Is Robert still abed?† Tyrion asked as he seated himself, uninvited, at the table. His sister peered at him with the same expression of faint distaste she had worn since the day he was born. â€Å"The king has not slept at all,† she told him. â€Å"He is with Lord Eddard. He has taken their sorrow deeply to heart.† â€Å"He has a large heart, our Robert,† Jaime said with a lazy smile. There was very little that Jaime took seriously. Tyrion knew that about his brother, and forgave it. During all the terrible long years of his childhood, only Jaime had ever shown him the smallest measure of affection or respect, and for that Tyrion was willing to forgive him most anything. A servant approached. â€Å"Bread,† Tyrion told him, â€Å"and two of those little fish, and a mug of that good dark beer to wash them down. Oh, and some bacon. Burn it until it turns black.† The man bowed and moved off. Tyrion turned back to his siblings. Twins, male and female. They looked very much the part this morning. Both had chosen a deep green that matched their eyes. Their blond curls were all a fashionable tumble, and gold ornaments shone at wrists and fingers and throats. Tyrion wondered what it would be like to have a twin, and decided that he would rather not know. Bad enough to face himself in a looking glass every day. Another him was a thought too dreadful to contemplate. Prince Tommen spoke up. â€Å"Do you have news of Bran, Uncle?† â€Å"I stopped by the sickroom last night,† Tyrion announced. â€Å"There was no change. The maester thought that a hopeful sign.† â€Å"I don't want Brandon to die,† Tommen said timorously. He was a sweet boy. Not like his brother, but then Jaime and Tyrion were somewhat less than peas in a pod themselves. â€Å"Lord Eddard had a brother named Brandon as well,† Jaime mused. â€Å"One of the hostages murdered by Targaryen. It seems to be an unlucky name.† â€Å"Oh, not so unlucky as all that, surely,† Tyrion said. The servant brought his plate. He ripped off a chunk of black bread. Cersei was studying him warily. â€Å"What do you mean?† Tyrion gave her a crooked smile. â€Å"Why, only that Tommen may get his wish. The maester thinks the boy may yet live.† He took a sip of beer. Myrcella gave a happy gasp, and Tommen smiled nervously, but it was not the children Tyrion was watching. The glance that passed between Jaime and Cersei lasted no more than a second, but he did not miss it. Then his sister dropped her gaze to the table. â€Å"That is no mercy. These northern gods are cruel to let the child linger in such pain.† â€Å"What were the maester's words?† Jaime asked. The bacon crunched when he bit into it. Tyrion chewed thoughtfully for a moment and said, â€Å"He thinks that if the boy were going to die, he would have done so already. It has been four days with no change.† â€Å"Will Bran get better, Uncle?† little Myrcella asked. She had all of her mother's beauty, and none of her nature. â€Å"His back is broken, little one,† Tyrion told her. â€Å"The fall shattered his legs as well. They keep him alive with honey and water, or he would starve to death. Perhaps, if he wakes, he will be able to eat real food, but he will never walk again.† â€Å"If he wakes,† Cersei repeated. â€Å"Is that likely?† â€Å"The gods alone know,† Tyrion told her. â€Å"The maester only hopes.† He chewed some more bread. â€Å"I would swear that wolf of his is keeping the boy alive. The creature is outside his window day and night, howling. Every time they chase it away, it returns. The maester said they closed the window once, to shut out the noise, and Bran seemed to weaken. When they opened it again, his heart beat stronger.† The queen shuddered. â€Å"There is something unnatural about those animals,† she said. â€Å"They are dangerous. I will not have any of them coming south with us.† Jaime said, â€Å"You'll have a hard time stopping them, sister. They follow those girls everywhere.† Tyrion started on his fish. â€Å"Are you leaving soon, then?† â€Å"Not near soon enough,† Cersei said. Then she frowned. â€Å"Are we leaving?† she echoed. â€Å"What about you? Gods, don't tell me you are staying here?† Tyrion shrugged. â€Å"Benjen Stark is returning to the Night's Watch with his brother's bastard. I have a mind to go with them and see this Wall we have all heard so much of.† Jaime smiled. â€Å"I hope you're not thinking of taking the black on us, sweet brother.† Tyrion laughed. â€Å"What, me, celibate? The whores would go begging from Dorne to Casterly Rock. No, I just want to stand on top of the Wall and piss off the edge of the world.† Cersei stood abruptly. â€Å"The children don't need to hear this filth. Tommen, Myrcella, come.† She strode briskly from the morning room, her train and her pups trailing behind her. Jaime Lannister regarded his brother thoughtfully with those cool green eyes. â€Å"Stark will never consent to leave Winterfell with his son lingering in the shadow of death.† â€Å"He will if Robert commands it,† Tyrion said. â€Å"And Robert will command it. There is nothing Lord Eddard can do for the boy in any case.† â€Å"He could end his torment,† Jaime said. â€Å"I would, if it were my son. It would be a mercy.† â€Å"I advise against putting that suggestion to Lord Eddard, sweet brother,† Tyrion said. â€Å"He would not take it kindly.† â€Å"Even if the boy does live, he will be a cripple. Worse than a cripple. A grotesque. Give me a good clean death.† Tyrion replied with a shrug that accentuated the twist of his shoulders. â€Å"Speaking for the grotesques,† he said, â€Å"I beg to differ. Death is so terribly final, while life is full of possibilities.† Jaime smiled. â€Å"You are a perverse little imp, aren't you?† â€Å"Oh, yes,† Tyrion admitted. â€Å"I hope the boy does wake. I would be most interested to hear what he might have to say.† His brother's smile curdled like sour milk. â€Å"Tyrion, my sweet brother,† he said darkly, â€Å"there are times when you give me cause to wonder whose side you are on.† Tyrion's mouth was full of bread and fish. He took a swallow of strong black beer to wash it all down, and grinned up wolfishly at Jaime, â€Å"Why, Jaime, my sweet brother,† he said, â€Å"you wound me. You know how much I love my family.†

Design and Evaluation of a Wind Turbine in Urban environment Assignment

Design and Evaluation of a Wind Turbine in Urban environment - Assignment Example Although the concept of wind turbines is old a large – scale development of a new generation of turbines for power generation began in the world. Winds contribution in the fight of global warming, the total carbon dioxide emissions avoided by wind power in 2009 is 1.93% of the worlds total emission from power generation. Even if a home wind turbine does not provide significant savings, it is more preferable when it comes to treating planet earth with more respect. In this project, we try to use this clean power in charging different devices such as cell phones and laptops among others. Calculating the power needed to charge such devices the turbine will be designed, and connected by a network providing power for such devices at home. The use of an alternative energy option is very helpful since it facilitates rural and local area electricity connection. For the case of the cost of the turbine tower, although the initial cost of purchase and installing of a turbine can be expensive in all ways but it saving money, and environmental resources. When such kind of projects are used widely, there will be a database for all the areas including the wind direction, wind speed and the suitable kind of turbine that may be used for each region. Study the wind atlas map for my home area in Egypt , " the new and renewable energy authority in Egypt " site provide reliable and accurate wind atlas data sets for evaluating the wind power output for any place in Egypt , studying the wind atlas will help with the data for the wind direction and the speed variation all the year. Blades are sensitive, and the most breakable part of the system, they are creating mechanical stress caused by centrifugal forces and fatigue, so designing the blades correctly is very important or else they will break or not function efficiently. The tower supports the parts and holds them
