Explain how oxygen and carbon dioxide are transported by the blood Assignment

Explain how oxygen and carbon dioxide are transported by the blood - Assignment Example The process of oxygen transportation by the blood involves transfer of oxygen from the lungs to the cells that need the oxygen for physiological and biological processes. The major factor in the oxygen transfer is the concentration gradient between blood and the two cites. The respiratory system inhales blood that is reach in oxygen and induces oxygen concentration gradient between the lung and the blood system. Oxygen then diffuses into the blood system for transportation through the system’s network that reaches all body cells. Many non-physical factors however facilitate the process that would otherwise be too slow to meet the need for oxygen. Physical transfer in which oxygen dissolves in the blood’s plasma only transport a limited amount of oxygen in the body, while the major transportation is aided by haemoglobin. Further, the level of oxygen that is transported through the chemical is a factor of â€Å"concentration of haemoglobin in the blood,† proportion of haemoglobin that is bound to oxygen and the chemical’s affinity to oxygen. The level of diffused oxygen into the blood is further a non-linear factor of oxygen concentration with a reducing gradient as oxygen concentration increases up to an optimal level at which the diffusion rate stabilizes. Oxygenated blood is then transported through the circulatory system whose extensive network connects to all body cells and organs. The cells have low oxygen concentration and this facilitates the transfer of oxygen into cells across cell membranes. Dissociation of oxygen from blood’s haemoglobin is however also influenced by factors such as presence of carbon monoxide, concentration of hydrogen ions, and temperature among other biological conditions such as anaemia (Porth 2010; Tortora and Derrickson 2009). The blood also transports carbon dioxide from cells to the lungs. The transfer occurs in three forms in which carbon dioxide diffuses from cells into

Topic 3 - Essay Example Consumer behavior is what the whole marketing theory and concepts are based on. By studying consumer behavior, marketers hope to find the reason why the consumer wants to buy a certain product. It aims to help and identify how people make their buying decisions and also the factors that influence those decisions. There are usually two kinds of buyers, organizational buyers and consumers. We are only concerned with the consumers who are the ones who buy services and products for use by themselves. They buy things that serve their need for living and the basic requirements of life. They also buy products to make the world know about their personalities and reveal their attitudes and their roles in the society. In other words they not only cater to the physiological needs but also the psychological aspect as well. Individuality is a characteristic that a man develops due to the nature and the surrounding environment he spends that life in. the behavior of a person towards buying a certain product will therefore be different for everybody. They might have different tastes, likes and dislikes, attitudes and values and their decision making process will differ according to that. The three major things that influence the consumer's social environment are individual circumstances, personal psychology and the social environment. All these above mentioned factors have a lasting impact on the individuals buying behavior. Factors Social environment in which an individual lives his or her life helps greatly in shaping the life of people and their preferences. The culture that they are prevailing in, the reference groups to which they belong and cater too and the social class they exist in or the one in which they want to exist in. There can be an informational influence over them for example when they are told about the authenticity of a certain product's working. A customer can also be influenced by the type of reference groups that he or she relates too. A marketer needs to identify the needs and influences of the reference groups of his target market in order to understand their consumer behavior and plan out their offer in such a way that coincides with the needs and wants of the customer and caters to his or her influence. A customer can be influenced by the 'family of orientation' which is the basic family or the parental family that a customer has; a daughter might end up using the same washing detergen t her mother uses. Another kind of reference group is the family of procreation that is more of the extended family; a customer's buying decision might be influenced with the house of his or her in-laws and he or she might to carry out different tasks and buy certain kinds of products in the presence of their extended family. Secondary groups are the less formal groups which the customer doesn't end up meeting everyday and therefore they don't pose a lot of influence over the buying decision behavior of the customer. Individual characteristics tend to stem from demographics characteristics. The gender of the person, the age group with which he or she is belonging to, the stage of the lifecycle the customer is catering to and the customer's

Accounting - Research Paper Example This chapter outlines the essence of harmony, and healthy working relations. It is crucial to note that, Dunlap has caused more harm than salubrious. Many companies remained ruined during and after Dunlap’s rein as executive officer (Hooper, 2003).

The Iraq War Research Paper Example | Topics and Well Written Essays - 2000 words

The Iraq War - Research Paper Example Without a doubt, the Iraq War was one of the more hotly-contested wars—many people arguing that this was the next Vietnam. Some eleven-thousand American lives later, it’s possible that some people would not agree. But the Iraq War, no matter how much precedent the U.S. had to invade, will always remain in the American mindset as a colossal financial drain. Here it will be attempted to: identify and describe the Iraq War; analyze the historical and contemporary causes of the Iraq war; analyze different historical interpretations of the Iraq war; and evaluate the positive and negative outcomes of the Iraq war. II. Identification and Description of the Iraq War The Iraq War was an armed conflict that took place beginning in Iraq in 2003. Although people now state that the Iraq War is technically over, there are still U.S. troops which are occupying Iraq. It was technically supposed to have ended a few years ago, but realistically, there are still American forces there, and there probably will be for some time to come. So, even though the war is technically designated as finished, it is still not finished—if that makes sense. There is no â€Å"over† for this war. The war began when President Bush acted (without Congressional authority) to unilaterally declare war on Iraq. According to Kelly (2001), â€Å"A huge controversy arose when President Bush sent troops into Iraq on March 19, 2003 claiming that the country led by Saddam Hussein was developing weapons of mass destruction and aiding Al Qaeda operatives†¦[however,] time passed and no evidence of those weapons were found in Iraq†¦Ã¢â‚¬  (pgh. 7). It was especially distressing to the American public to find out that there were, indeed, no weapons of mass destruction found in Iraq. This angered much of the public and made many Americans feel like they were tricked into going into an armed conflict without all of the available evidence laid before them first. This was a major faux pas that continues to be rehashed in the media whenever people argue about whether or not the U.S. should have invaded Iraq; it will probably be a sore spot for years to come. III. Analysis of the Historical and Contemporary Causes of the Iraq War Historically speaking, the rationale that President Bush used for going to war with Iraq was the advent of 9/11. According to Hanson (2004), â€Å"[T]here is a direct connection between Iraq and our current war on terror†¦Whether or not one believes Iraq was involved at the planning in 9/11, there is proof that it had something to do with the first World Trade Center bombing, had intelligence meetings with†¦Al Qaeda [members], [and] tried to assassinate a former president of the United States†¦Ã¢â‚¬  (pp. 245). Although 9/11 is traditionally associated with the main reasons for why Bush began his â€Å"war on terror,† another reason that many people feel he went to war with Iraq was to settle an old score with Saddam Hussein for having engaged in conflict with his father (Bush 41) in Operation Desert Storm. Many people feel that one of the sole reasons that Bush went to war with Iraq was so that he could feel vindicated on the behalf of his father. One of the contemporary causes of the Iraq War was also the fact that U.S. companies stood to make millions of dollars off of the war. Vice President Dick Cheney’s construction company Halliburton was called into Iraq for most of the reconstruction of the

The institution conducts majority of its educational endeavors to accomplish the three main objectives, which has been enumerated in the University’s Plan documents. ASU’s main objective is to provide higher education to the maximum number of US students that it can accommodate. The University makes its students undergo a standardized curriculum in their respective subjects and also encourages them to pursue research on their own. Finally, the institution ensures that all its academic endeavors are conducted in a way so as to improve the economic, social and cultural welfare of the surrounding social community. These have been identified as the vision of the ASU. The vision statements of the University reflect the inhere nt objectives of the institution. The statements can be further analyzed to provide some useful insight into the ASU authorities’ long-term goals. Most of the elite higher educational institutions have always set very high standards for the students aspiring to secure admission in them. However, the objectives of the ASU have been stated to be quite different in this respect. Instead of aiming to exclude the undeserving students, the University always looks to include the maximum number of students under its educational programs. ...

However, the objectives of the ASU have been stated to be quite different in this respect. Instead of aiming to exclude the undeserving students, the University always looks to include the maximum number of students under it s educational programs. Simultaneously, ASU has also concentrated in providing these students with a high standard of higher education. Therefore, the institution has been successful in achieving the twin objectives of making higher education accessible to a larger population of students, as well as securing a good reputation regarding the standard of education offered (ASU Vision and Goals, 2011). The ASU has also declared certain additional aims and objectives which it plans to implement by the year 2012. One such objective is to become a ‘National Comprehensive University’ by the specified timeline. The institution has set its sights in becoming the leading educational center for various scientific disciplines which also

Creating Public Value through the Weatherization Assistance Program Research Paper

Creating Public Value through the Weatherization Assistance Program - Research Paper Example With the total of $10 million stimulus funding, the Boston ABCD Weatherization program has the capacity to subject 1,800 homes to weatherization (Massachusetts Commonwealth, 2012). As soon as the Ramirez family qualified for the program, weatherization professionals immediately assessed the house’s energy consumption. The assessment, which took around two to four hours, found that the house had no proper wall insulation; its doors invite cold air in, and water leaks are found in the basement. From these observations, weatherization professionals reported their assessment to the homeowners and presented what needs to be repaired in the house to save energy cost Through the stimulus package, the Boston ABCD provided for the house’s insulation and new doors in the house. They also installed a new bathroom to prevent the place from molding. After these repairs, the family was able to reduce their electric bills up to 45%, especially during the winter. According to Mrs Ramirez, she was thankful for the program because her family finally experienced warmth in winter for the first time (Massachusetts Commonwealth, 2012). The article above represents the actual account in the implementation of the Weatherization Assistance Program (WAP), a long-running public program for low-income families that enables them to reduce their energy consumption and ensure energy efficiency at home through weatherization. The federal government, together with the Department of Energy (DOE) and local weatherization agencies work together to take responsibility in maintaining the national energy policy of the United States.

Is China a Threat to Indian Industry Essay Example for Free

Is China a Threat to Indian Industry Essay Renewable energy has huge potential to provide solution to increase energy crisis and it is the key factor to the future of energy, food and economic security, said participants at a seminar organized by greentech and Bengal National Chamber of Commerce and Industry. We are a growing economy. So our energy requirement is also growing. But we dont produce enough energy to meet even our current needs. With depleting fossil fuel reserves and concerns about its environmental impact, renewable energy is the only long-term solution, said Bibek Bandhopadhyay, advisor at the ministry of new and renewable energy. At present, Indias installed power capacity is 2,10,645 MW with renewable energy contributing 26,900 MW or 12.4%. From various energy technologies, a capacity addition of about 30,000 MW has been planned during the 12th Plan period 2012-2017. The focus is now on mainstreaming renewable energy technologies so that it becomes cost-effective. Of this, 69% is generation from wind and 4.5% from solar. Incidentally, India was the first country to set up a ministry of non-conventional energy resources in the early 1980s. India is densely populated and has high solar insolation, an ideal combination for using solar power in India. Much of the country does not have an electric grid, so one of the first applications of solar power has been for water pumping, to begin replacing Indias 4-5 million diesel powered water pumps, each consuming about 3.5 kilowatts, and off-grid lighting. Some large projects have been proposed, and a 35,000 sq km area of the Thar desert has been set aside for solar power projects, sufficient to generate 700 to 2,100 GW. The Indian Solar Loan Programme, supported by the United Nations Environment Programme has won the prestigious Energy Globe World award for sustainability for helping to establish a consumer financing program for solar home power systems. Over the span of three years more than 16,000 solar home systems have been financed through 2,000 bank branches, particularly in rural areas of south India where there is no grid electricty. Launched in 2003, the Indian Solar Loan Programme was a four-year partnership between UNEP, the UNEP Risoe Centre, and the Canara Bank and Syndicate Bank. Announced in November 2009, the Government of India proposed to launch its Jawaharlal Nehru National Solar Mission under the National Action Plan on Climate Change with plans to generate 1,000 MW of power by 2013 and up to 20,000 MW grid-based solar power, 2,000 MW of off-grid solar power and cover 20 million sq metres with collectors by the end of the final phase of the mission in 2020. Development of wind power in India began in the 1990s and has increased in recent years. Although a relative newcomer to the wind industry compared with Denmark or the US, domestic policy support for wind power has led India to become the country with the fifth largest installed wind power capacity in the world. As of December 2010, the installed capacity of wind power in India was 13,065.37 MW, mainly spread across Tamil Nadu, Maharashtra, Karnataka, Rajasthan, Gujarat, Andhra Pradesh, Madhya Pradesh, Kerala and West Bengal. Wind power accounts for 6% of Indias total installed power capacity, and it generates 1.6% of the countrys power. Every year, about 55 million tonnes of municipal solid waste and 38 billion litres of sewage are generated in the urban areas of India. In addition, large quantities of solid and liquid wastes are generated by industries. Waste generation in India is expected to increase rapidly in the future. As more people migrate to urban areas and as incomes increase, consumption levels are likely to rise, as are rates of waste generation. It is estimated that the amount of waste generated in India will increase at a per capita rate of approximately 1-1.33% annually. This has significant impacts on the amount of land that is and will be needed for disposal, economic costs of collecting and transporting waste, and the environmental consequences of increased MSW generation levels.
