Defining Active and Passive Transport
Active and passive transport processes are two ways molecules and other materials move in and out of cells and across intracellular membranes. Active transport is the movement of molecules or ions against a concentration gradient (from an area of lower to higher concentration), which does not ordinarily occur, so enzymes and energy are required. Passive transport is the movement of molecules or ions from an area of higher to lower concentration. There are multiple forms of passive transport: simple diffusion, facilitated diffusion, filtration, and osmosis. Passive transport occurs because of the entropy of the system, so additional energy isnt required for it to occur. Compare Both active and passive transport move materials and can cross biological membranes. Contrast Active transport moves materials from lower to a higher concentration, while passive transport moves materials from higher to lower concentration.Active transport requires energy to proceed, while passive transport does not require the input of extra energy to occur. Active Transport Solutes move from a region of low concentration to high concentration. In a biological system, a membrane is crossed using enzymes and energy (ATP). Passive Transport Simple Diffusion: Solutes move from a region of higher concentration to lower concentration.Facilitated Diffusion: Solutes move across a membrane from higher to lower concentration with the aid of transmembrane proteins.Filtration: Solute and solvent molecules and ions cross a membrane because of hydrostatic pressure. Molecules small enough to pass through the filter may pass.Osmosis: Solvent molecules move from lower to higher solute concentration across a semipermeable membrane. Note this makes the solute molecules more dilute.Note: Simple diffusion and osmosis are similar, except in simple diffusion, it is the solute particles that move. In osmosis, the solvent (usually water) moves across a membrane to dilute the solute particles.

Pest Analyse free essay sample
Started in 1813, the company has grown from a small enterprise into a multi-national corporation. The growth has been necessitated through business ventures mainly acquisitions. [1]The company has throughout in its lifetime been acquiring smaller cloth and cosmetics manufacturing companies the first one being Marshall  amp; Snelgrove in 1919. Debenhams manufactures cloth wear both for domestic use and also for export purposes. Much of their products are exported in the European, Asian and African nations including the US market[2]. The target group of Debenhams includes children, who buy children’s wear, women (women’s wear) and men (Men’s wear). Other target groups are: cosmetic shops; large super-markets and other processing companies. The products range from wedding dresses to school uniforms. Its policy is to analyse and identify what customer specifications are and design the cloths accordingly. Technologically, the company has re-shaped its manufacturing methodologies that have produced the latest fashions [3]of clothes in the market. These have attracted a large number of customers. The following table can help illustrate how the demand for cloth wear for different categories of its target groups has been trending for the last four years. The demand is in terms of the revenue realized from the sale of clothes and cosmetics. GROUP| 2003? | 2004? | 2005? | 2006? |  | Children| 649440| 752386| 798467| 863258|  | Women| 859035| 874903| 904567| 943567|  | Men| 534786| 587325| 604879| 698346|  | Cosmetics| 587024| 645828| 644098| 703378|  | Debenhams employs the e-business technology [4]to strategically advertise its products. It also uses e-business to identify any emerging trends in customer demands as well as studying the activities of rival companies. Stiff competition comes from Alexon Group plc and Arcadia Group plc. Debenham’s main resources requirements are among others, wool, cotton and Chemicals for making cosmetics. Other resources are; transportation facilities as some of these raw materials have to be transported from far countries. The company is however faced with the ever dynamic environmental factors in which it operates. These are both external and internal to the organization. These are Political, environmental, Social and Technological (PEST). 5]ANALSIS OF THE EXTERNAL’ STRATEGIC ENVIRONMENT OF DEBENHAMS PLC. USING PESTPEST is a tool that is used to analyse enterprises in terms of the political, economic, social and technological environment. THE POLITICAL ENVIRONMENT Debenham’s activities are stringently regulated by various political sources. In the fi rst place, there exists a government regulation at the source nations. For instance, expiry dates for cosmetics vary from country to country for two or more products produced within the same date of manufacture. The U. K government does regulate the health and safety conditions that workers of Debenhams plc have to work in. Also under regulation, is the minimum wage of workers. Some political factors have favourably affected the operations of Debenhams. An example is the compulsory recycling laws. These have enabled Debenhams to save on its costs of raw materials as these have to sometimes be recycled. THE ECONOMICAL ENVIRONMENT Approximately 30% of UK budgetary revenue is based on domestic borrowing. This money is raised mainly through taxation[6] and corporates like Debenhams are taxed at rates that are quite high. Inspite of the allowance of a tax holiday to some competitor companies, Debenhams does not enjoy this facility. This adversely affects its profits. Debenhams relies on external sources of finance i. e. fixed charge capital to finance its operations. These sources of finance are associated with fixed interest payments. The economical ramifications of these huge financial costs are that it may affect Debenham’s financial position . The following graph depicts how Debenham’s financial risk has been responding to changes in Leverage (gearing). 8Level ofFinancial Risk   6                         4                                               2         | | |                       4                      6                      8                                    Leverage/gearingThe other economical challenge that has faced Debenhams is that products from rival companies have also flooded the market, being cheap and readily available. They are a formidable competition to Debenhams. THE SOCIAL ENVIRONMENTOne of the greatest social challenges of Debenhams is change of tastes and fashions. Many are times when sales show a declining trend as a result of consumers shifting to other products. Before marketing and selling their products, Debenhams must consider factors like customs and believes of a people. [7]There are some geographical areas like the Muslim communities where certain clothing are prohibited due to their religious believes. Such factors tend to hinder Debenham’s operations. TECHNOLOGICAL ENVIRONMENTWith the advent of computerization, many of Debenham’s plant machinery have been rendered obsolete because they are analogue as opposed to digital. There is a need to buy new computerized systems that will increase efficiency in production. However, Debenhams has embarked in a rapid computerization program and has hired consultancies and professionals to fast track the process. Debenham is also pursuing a strategic plan of five years that factors in probable challenges and advancement and has also hired the services of a consultancy firm. By integrating the e- business system and other advertisement modes in the electronic media like blackberrie, T. V and other electronic media, there has been an increase in orders placed by potential consumers. This has seen the sales turnover rising from ? 24bn in the year ended 31st December 2005 to ? 8bn for the period ended 31st December 2006. Extending corporate responsibility to social responsibility would greatly and favourably affect its customers and local community at large. Proper financial accounting and disclosure of relevant information to the accounts would also help build investor confidence. Another internal factor likely to influence the operations of Debenham is how well the management has addressed the issue of Quality control. In order for their products to gain popularity, they must integrate a system of quality development and quality maintenanceInternal factors like employee satisfaction greatly determine the level of performance in the organization. To curb its devastating effects, the management of Debenhams has adapted a democratic style of management. Decision- making is decentralized , and any changes are brought soberly. CONCLUSION In conclusion, Debenhams exists within a balance of both the external and internal environments. This balance involves complex financial systems geared towards servicing its credit system, employee satisfaction and making profit. The research and development section that is carrying out the employee training under Human resource management makes the employees of Debenham have an edge over it competitors. In addition the technological improvements in its production unit have spurred the mass production of its products while maintaining quality. In essence this has given Debenhams credit in international quality awards. The market for this U. K outfit has penetrated and is increasingly becoming a dominant presence in the European continent and the USA.

Polyphemus Polyphemus according to Greek mythology was the son of Poseidon and the nymph-thoosa. In all of my research on Polyphemus I have found that he has no powers, nor does he have symbols. But besides his enormous size and his herding of goats and sheep. He has no other powers and symbols The Cyclopes definition means round eye. A mythical semi-human monster of huge proportions. A single eye at the center of his forehead. Usually described as one round-eyed giant. Polyphemus is best remembered in homers poem The Odyssey when Polyphemus captures Odysseus and his crew on their way home from the Trojan War. His crew lands on the Island of Cyclopes in search of Provisions. After finding polythemuses cave and went inside to steal food and he also was curious to see what a Cyclopes looks like he had never seen one before. So Odysseus and his men hid waiting for the Cyclopes to return. When he returned Odysseus and his men gasped in disbelief. Giving away their hiding place. So polythemus closes his cave with a big boulder, after he trapped him Odysseus told the Cyclopes that his name was nobody. His biggest problem was the he and his men could not lift the boulder therefore they can not kill polythemus. So polythemus ended up eating 4 of his men total since they like raw meat it doesnt matter what kind just as long as it is raw. And after that polythemus goes for a walk around the island with his flock of sheep when he was gone Odysseus put a sharpened log into poop to hide it. Upon his return polythemus drinks wine that Odysseus gave him, what he doesnt know is that the wine he drank is very powerful that a Greek god gave him. So from that point Polythemus passes out. From that point Odysseus and his men take the spear and drop it in his eye Putting him in a panic. Looking for Odysseus and his men lifts up the boulder and waits at the door. So Odysseus and his men cling to the bottom of the sheep escaping from polythemus. Then polythemus shouts and pounds so the other cylopses come to his call and they ask what is the matter and he says that I am blined by nobody. And they say then what is wrong and polythemus says, no I was blinded by nobody. So they leave him alone at that point. Theater Essays
