Science Questions - Essay Example Living systems in a region may contain wetlands, prairies, coral reefs, rainforests, tundra, or the canopy of an old growth forest. Ecosystem services would comprise the capability of nature to assimilate waste, turn sunlight into edible plants, and create oxygen. With in this natural source we can be able to come up of a natural income. There are lots of natural capitals that can be a source of natural income. An example of natural capital is the water get from springs which are then processed and purified and be sold as mineral or distilled water. This kind of natural capital and natural income can be able to sustain resource by preserving the natural resource itself. The company that sells this drinking water can put up their business site where they get their water. They can make strategies to put up the building in such a way that it will also look like a resort to customers. They will take care of the trees and the water flowing there so that it can replenish itself. Cleanliness should also be maintained and the owner should establish ecological ethics to refrain from any environmental issues that may lead to the downfall of the business. In this way, it will be attractive for customers to come along and buy the product. According to Wikipedia (2006), primary production is is the fixation of light energy into chemical compounds (the construction of sugars from CO2 and water; photosynthesis). Gross primary production then refers to the total amount of energy fixed by plants (the primary producers). This energy can then be used by plants to generate new biomass; growing. While net productivity according to Kimball’s Biology Page (2004) refers to the amount of energy trapped in organic matter during a particular interval at a given trophic level. The quantity of the trapped energy of the plants (net productivity) will then be processed (H2O, CO2, and sunlight) by plants into starch is called primary gross. Biodiversity has been

The Effective Manager Cw3 Coursework Example | Topics and Well Written Essays - 1500 words

The Effective Manager Cw3 - Coursework Example The mangers are responsible for the optimum utilization of resources in order to achieve the goals of the organization. Management is a set of activities which is directed towards the resources of the organization with a aim of achieving the required goal in an effective and efficient manner. In general a successful organization comprises of both effective as well as efficient mangers. In the competitive world managers tends to face new as well as interesting and challenging situations. The average working time is about 60 hours per week and has a huge demand place upon the mangers time and at the same time faces complexities due to globalization, completion, government regulations and other uncertainties. The job role of a manger is unpredictable and filled with challenges but it is also filled with opportunity which has the potential to make difference. Good managers have the potential to bring in success in the organization (Griffin, 2011, p.4). ... The quality and effective management styles of the mangers can determine the organizational culture, productivity of the staff and success or failure of the organization (Francis, 2012). Characteristics of Effective Management An effective manger is one who makes the right decisions and successfully implements the decisions. However there are many different characteristic that a manger should posses for the effective working of the organization. But according to me the most important characteristic for a manger should be a good team player and time management should be the next important characteristic for an effective manger. A team builder can be defined as a person who is strong and provides the required substance which holds the team together towards achieving the set goals and objectives (Francis, 2012). At the same time effective time management skills are important for mangers to perform the task. I would like to emphasis more on the aspect of time management. Literature defin itions With respect to the definition of time management, there are many different definitions as per different authors. However most of the authors referred to Lakein (1973) who said that time management involve a process which determines the need sets the goals which are to be achieved, planning and prioritising the task which are required in the process of achieving the goals. Therefore according to Elacqua and Jex, 1999; Davis, 2000; Macan, 1994, 1996; Macan et al., 1990; Mudrack, 1997) time management has been referred to as a technique used to manage time; a technique which can be used for effective use the many different task which are required Orpen, (1994) Slaven and Totterdell, (1993); Woolfolk & Woolfolk, (1986); according to

Effects Of Raw Sewage Discharged Directly Environmental Sciences Essay

Effects Of Raw Sewage Discharged Directly Environmental Sciences Essay Throughout history of existence of man, getting rid of waste man produces has always been problematic. Our Palaeolithic and Neolithic ancestors also had the same problem of waste disposal, those who lived on oysters and other shellfish simply threw the waste out forming the kitchen middens which are now of great interest to the archaeologists (Anderson, 2007). During the medieval times sewage and domestic waste was thrown everywhere and ended up flowing into nearby water bodies. Around 1900s, the system of sewers evolved, cities did not treat sewage during that time (Ward, 2010). They simply collected the raw or untreated sewage (wastewater) using the system and discharged it into a receiving body of water either a river or a marine environment (Anderson, 2007) dictated by the location of the city. However, it soon became apparent that raw sewage discharged in this manner was inadequate for two major reasons being; the adverse ecological impacts on receiving waters and the adverse public health impacts since some of the microorganisms in raw sewage may be pathogenic (Ward, 2010) hence the receiving water bodies cannot be used for water contact sports like swimming and water skiing. Now municipal councils worldwide have gone to a great extent of constructing sewage treatment plants to keep up with pace of increasing human population, which tend to generate more sewage. These modern municipal sewage treatment systems utilize microbial degradation as a principal way to degrade these organic and inorganic material contained in waste water. The ecological impacts of discharging raw sewage into rivers are dictated by the constituents of the waste. Sewage contains vast amounts of organic material, also inorganic materials such as nutrient salts consisting mainly phosphate and nitrate from partial mineralisation of the organic matter and detergents where phosphates are used as dispersion and suspension agents (Nixon, 2009). Run-off from industries and gardens also end up in the sewage. This can probably contain traces of heavy metals such as mercury and uranium(Landman and Ling, 2011). Microorganisms both living and dead also contribute to the amount of organic material present in the sewage, the latter is a pollutant. Discharging raw sewage into rivers therefore introduces these constituents of sewage into the aquatic ecosystem. Organic material will therefore serve as a substrate for the growth of heterotrophic bacteria. The aerobic respiration activities of these microorganisms remove the dissolved oxygen in water, creating an anoxic condition. This condition is lethal to fish and other oxygen requiring living organisms in the river (Landman and Ling, 2011). Biodiversity in the aquatic system is thus hampered due to reduction of other living species population in the river. Also other terrestrial organisms depending on the river water will be affected negatively since the water is no longer in state that is conducive for them to use (Nixon, 2009). Wastes released by the microorganism tend to be toxic to other living organisms. Also animals that drink on the river that contain sewage can end up acquiring the heavy metals that concentrate up the food chain hence endangered species could be wiped o ut as a result of the toxicity of the heavy metals (Ward, 2010). Since pH and temperature have effect on the solutes in the waste water, low or high will lead to cations in water complexing with the phosphate hence precipitates (Nixon, 2009). These precipitates will change the aesthetic appearance of water. Also the precipitates can be bound to aquatic organism such as fish hence blocking their pores on their bodies that are responsible for gaseous exchange. Public health impacts due to raw sewage in rivers are that the river can longer be used as a source of drinking water and for human consumption. The river water thus tend to have a high concentration of nitrates, which are toxic to human especially infants as it can cause a disease known as blue baby syndrome (Anderson, 2007). This disease results due to high affinity of nitrates to haemoglobin hence less oxygen is carried in the blood. Water borne microorganisms such vibrio cholera from human faeces (Moubarrad,. et al 2007) also can be contained in the water hence if water is used for human consumption, this can lead to spread of diseases. Water contact sport also can be performed on such water due to the contamination by organic matter and bad odour as a result of the raw sewage. Even though the water can be rich in plant nutrients, it cannot be used for irrigation purposes in agriculture since heavy metals that are contained in the water can end up finding their way into crops. Heavy metals such as mercury in water can be converted to methylmercury by bacteria (Ward, 2010). Methylmercury is a neurotoxin in human that affect the nervous system and brain functioning hence it can cause permanent development defects in babies (Moubarrad,. et al 2007) . Since the severity of the impact of raw sewage discharged into rivers varies due to the volume of the raw sewage, organic and inorganic material content and the flow rate of water in the river, therefore when rivers are given sufficient time without further pollution, rivers have the natural capability to restore themselves (Ward, 2010). Oxygen can be reintroduced into the water through two activities being; oxygenic photosynthesis by cyanobacteria, algae and aquatic plants and also by the turbulence of the river, which results in the diffusion of oxygen from air. In addition, the organic material component of raw sewage is eventually degraded by the heterotrophic bacteria and when it depletes the population of these bacteria declines (Anderson, 2007). However in the case of lakes, deposition of raw waste triggers a phenomenon known as eutrophication since water in lakes is not flowing. Eutrophication results from nitrates and phosphates contained in raw sewage being turned into cellular mass by microorganisms in presence of light ( HobÆK,. et al 2012). Eventually water is covered with green mats of algae, blocking sunlight and gases to diffuse into the water hence organisms rising in water die due to insufficient oxygen. A high population of microorganisms especially anaerobic ones results and this enhances other predatory microorganisms to reside in the water being attracted by the high populations of their prey. Due to eutrophication, biodiversity will be lost in terms of reduction in populations of organisms residing in water. Lakes compared to rivers are not capable of quick self-restoration since water in them is stagnant therefore diffusion of gases cannot be possibly easy.

Sex in the Media Essay -- Television Commercial Advertising Essays

Sex in the Media One of the most important resources of a business is its advertisement team. Due to the fact that people can and will buy your product only if they know about it. This is the reason that marketing and advertisement have the biggest budgets in a business. This is the reason that places such as Amazon.com spend up to four million dollars on advertisement a year, according to 'Dream-Biz.com' written by Burke Hedges. There is a saying that goes 'Sex-sells' is this true? Most people would argue that it does. Since choosing this topic it has forced me to see everything different. When I sit and watch television I can?t help but notice all of the strong sexual messages that are being thrown at me every second. This project will touch on many venues of advertisement, from television to radio and even printed advertisement. It seems to me that sex is being used to sell everything. It has become custom to see promotions for a movie that would have a hot and seductive scene, or even in a music video; which have become short movies themselves. I feel that the use of sex in advertisement has gone a little too far, when sex is used to sell juice that?s were I draw the line. Snapple had a campaign to reach ages 18-24 year old consumers. Their previous commercials targeted consumers in their 30?s and 40?s. Their new campaign was supposed to reach a broad spectrum of demographics while continuing to appeal to older Snapple fans. So what did they use ?Sex?. Fruit sex, that is. These commercials have the familiar fruit faces of Snapple?s prior commercials; just a little racier depiction of these ads with references to sex and jail.

Arc Assembly and Continental Collision

Arc Assembly and Continental collision in the Nonprescription East African Oregon: implications for the consolidation of Gondola's The Pan African Organic cycle, Is derived from Kennedy's (1964) term, Pan-African Thermo-tectonic episode to characterize the thermal differentiation of Africa into cartons and into mobile belts during the late Precambrian (now known as Nonprescription) and earliest Phoenician (Paleozoic) In 1981 McMillan argued that Gondola's was assembled from 2 fragments east and west Gondola's and he thought that this occurred along the Monomaniac Belt and Its extension to the north (Arabian-Nubian Shield) In 1984Kronor refined this term (Pan-African) to be involving a protracted organic cycle from 950 – 450 Ma ( a span of 500 Ma). The tectonics associated with this Is not restricted to Africa alone. Events to similar age occur throughout Gondola's (all the southern continents) but also Laurie (made up of Baltic [most of northern Europe and European Russia] Ast rakhan [Central Asia. China and Malaysia, Siberia {475 – 490 Ma} ) and Laurent (North America and Gondola's) with which it collided. The timestamp of 500 Ma is much longer than any Phoenician rookery.So preference to the Pan-African organic cycle must suffice until the timing and regional extent of discrete tectonic events is better understood and constrained. Uranium- lead dating would be recommended because it has a small error margin of 2 Ma.

Godfather Goodfellas Essay

The Godfather and Goodfellas are both considered â€Å"mafia movies. † Both of these films portray some form of organized crime committed by Italians. They mutually romanticize the mob lifestyle and depict it with pure clarity. Although both of these movies portray the lives of the same kind of people, they are more than just a simple characterization. Violence plays a major role in each of these films. The Godfather and Goodfellas are obviously very similar. However, they also have several aspects that differ from one another. In both The Godfather and Goodfellas, violence penetrates the daily lives of both Henry Hill and Michael Corleone.Although violence is a key factor of each of the movies, Goodfellas is more brutal in comparison to The Godfather. In the film Goodfellas, Henry Hill was exposed to the gangster lifestyle since he was very young. In the film Henry says, â€Å"As far back as I can remember, I wanted to be a gangster. † His out-of-control partner, Tommy is one of the most violent characters in the film. Blood shed is frequently joked about in this movie. In one of the scenes, Tommy was telling a story in a restaurant. After the story Henry laughs and tells Tommy that he is funny.Upon hearing this, Tommy gets defensive and loses his temper. For a moment Henry is nervous because he knows Tommy’s violent personality. However, he realizes that hw is joking and they all laugh about it. Tommy proceeds to wave his gun around and joke about killing Henry. This scene proves that murder is taken lightly in this movie. Another violent act is when Tommy brutally beats a mobster named Billy Batts to death. He kills Billy for insulting him about his younger years as a shoe shine boy. In this scene even Henry looks appalled. Tommy shows no remorse as they hide the evidence of Batts’ body.He continues to surprise the characters with his short temperedness and violence. Another shocking vicious act is when he kills Spider because he was disrespecting him. This scene leaves both the viewers the characters in the film appalled. There are many scenes in Goodfellas with a great deal of blood shed. Many of these murders happen spontaneously and are not organized. Some of these scenes are shocking, primeval, and appalling. These moments leave the viewers stunned and disoriented. Unlike Goodfellas, the violence in The Godfather occurs mysteriously and almost magically.The organized crimes and murders simply occur without any mistake in this film. One of the bloody scenes that portray this is the one where Woltz’ bed is covered in blood. This scene was very slick the way Tom Hagen slipped away without being noticed by anyone. Hagen’s visit was to intimidate Woltz by proving that if he had to kill him, he would be able to. Another very violent act was Sonny’s death. This plan was organized carefully by Don Emilio Varzini with the help of Carlo Rizzi, his brother-in-law. Earlier in the film Sonny had beaten Carlo after he heard Carlo was abusing his sister Connie.To get back at him, Carlo viciously beats Connie using his belt. When Sonny hears of this he speeds to Connie’s apartment. As he approaches, Barzini’s men surround Sonny and viciously shoot him to death. This act was also thought out very cautiously by masterminds. Towards the end of the movie, the planned killing of the five other mob leaders is revealed. Michael orders all of the head of the families to be killed so he can be the top Don. Although this scene is violent, it is masked by the ceremony of Michael becoming Connie’s son’s godfather.The mass murder was perfectly planned to take place at the right time and place. Every slaughter and violent act in The Godfather is carefully intentional and prearranged by their specific mastermind. Unlike The Godfather which portrays Mafia dons, Goodfellas shows the lives of the criminals who exist on a lower level. Both Henry Hill and Michael Corl eone face murders and beatings every day. Goodfellas is more upfront and brutal towards violence in comparison to The Godfather. The violent acts in Goodfellas are appalling and unpredictable.It perfectly portrays the ferociousness of the characters, specifically Tommy. Unlike Goodfellas’ obviously violent and vicious blood scenes, The Godfather is more sneaky and slick. The violence in this movie, while prevalent, is well masked and planned. Each murder was clearly thought out and intentional. Violence is one of the key components in a mobster’s life. The characters in both The Godfather and Goodfellas face murder in their mob lifestyles frequently. Although violence is dominant in both of these films, each film has a different way of portraying these bloody scenes.
