Running Physiology The Effects Of Altitude On Human Physiology Changes in altitude have a profound effect on the human body. The body attempts to maintain a state of homeostasis or balance to ensure the optimal operating environment for its complex chemical systems. Any change from this homeostasis is a change away from the optimal operating environment. The body attempts to correct this imbalance. One such imbalance is the effect of increasing altitude on the body's ability to provide adequate oxygen to be utilized in cellular respiration. With an increase in elevation, a typical occurrence when climbing mountains, the body is forced to respond in various ways to the changes in external environment. Foremost of these changes is the diminished ability to obtain oxygen from the atmosphere. If the adaptive responses to this stressor are inadequate the performance of body systems may decline dramatically. If prolonged the results can be serious or even fatal. In looking at the effect of altitude on body functioning we first must understand what occurs in the external environment at higher elevations and then observe the important changes that occur in the internal environment of the body in response. HIGH ALTITUDE In discussing altitude change and its effect on the body mountaineers generally define altitude according to the scale of high (8,000 - 12,000 feet), very high (12,000 - 18,000 feet), and extremely high (18,000+ feet), (Hubble, 1995). A common misperception of the change in external environment with increased altitude is that there is decreased oxygen. This is not correct as the concentration of oxygen at sea level is about 21% and stays relatively unchanged until over 50,000 feet (Johnson, 1988). What is really happening is that the atmospheric pressure is decreasing and subsequently the amount of oxygen available in a single breath of air is significantly less. At sea level the barometric pressure averages 760 mmHg while at 12,000 feet it is only 483 mmHg. This decrease in total atmospheric pressure means that there are 40% fewer oxygen molecules per breath at this altitude compared to sea level (Princeton, 1995). HUMAN RESPIRATORY SYSTEM The human respiratory system is responsible for bringing oxygen into the body and transferring it to the cells where it can be utilized for cellular activities. It also removes carbon dioxide from the body. The respiratory system draws air initially either through the mouth or nasal passages. Both of these passages join behind the hard palate to form the pharynx. At the base of the pharynx are two openings. One, the esophagus, leads to the digestive system while the other, the glottis, leads to the lungs. The epiglottis covers the glottis when swallowing so that food does not enter the lungs. When the epiglottis is not covering the opening to the lungs air may pass freely into and out of the trachea. The trachea sometimes called the windpipe branches into two bronchi which in turn lead to a lung. Once in the lung the bronchi branch many times into smaller bronchioles which eventually terminate in small sacs called alveoli. It is in the alveoli that the actual transfer of oxygen to the blood takes place. The alveoli are shaped like inflated sacs and exchange gas through a membrane. The passage of oxygen into the blood and carbon dioxide out of the blood is dependent on three major factors: 1) the partial pressure of the gases, 2) the area of the pulmonary surface, and 3) the thickness of the membrane (Gerking, 1969). The membranes in the alveoli provide a large surface area for the free exchange of gases. The typical thickness of the pulmonary membrane is less than the thickness of a red blood cell. The pulmonary surface and the thickness of the alveolar membranes are not directly affected by a change in altitude. The partial pressure of oxygen, however, is directly related to altitude and affects gas transfer in the alveoli. GAS TRANSFER To understand gas transfer it is important to first understand something about the behavior of gases. Each gas in our atmosphere exerts its own pressure and acts independently of the others. Hence the term partial pressure refers to the contribution of each gas to the entire pressure of the atmosphere. The average pressure of the atmosphere at sea level is approximately 760 mmHg. This means that the pressure is great enough to support a column of mercury (Hg) 760 mm high. To figure the partial pressure of oxygen you start with the percentage of oxygen present in the atmosphere which is about 20%. Thus oxygen

The Difference Between an Embassy and a Consulate

The Difference Between an Embassy and a Consulate Due to the high level of interaction between countries in our interconnected world of today, diplomatic offices, such as embassies and consulates, are needed in each country to aid in and allow such interactions to occur. Ambassadors are their countrys government representatives abroad in matters between the two countries. These offices also provide services for potential emigrants and international travelers. Although the terms embassy and consulate are often used interchangeably, the two are different. Definition of an Embassy An embassy is larger and more important than a consulate and is described as a permanent diplomatic mission, which is generally located in a countrys capital city. For example, the United States Embassy in Canada is located in Ottawa, Ontario. Capital cities such as Ottawa, Washington, D.C., and London are home to nearly 200 embassies each. An embassy is responsible for representing the home country, for handling major diplomatic issues (such as negotiations), and for preserving the rights of its citizens abroad. The ambassador is the highest official in the embassy and acts as the chief diplomat and spokesperson for the home government. Ambassadors are typically appointed by the highest level of the home government. In the United States, ambassadors are appointed by the president and confirmed by the Senate. Usually, if a country recognizes another as being sovereign, an embassy is established to maintain foreign relations and provide assistance to traveling citizens. Embassy vs Consulate By contrast, a consulate is a smaller version of an embassy and is generally located in the larger tourist cities of a country, but not the capital. In Germany, for instance, the U.S. consulates are in cities such as Frankfurt, Hamburg, and Munich, but not in the capital city of Berlin. The embassy is located in Berlin. Consulates (and their chief diplomat, the consul) handle minor diplomatic issues such as issuing visas, aiding in trade relationships, and taking care of migrants, tourists, and expatriates. In addition, the United States has Virtual Presence Posts (VPPs) to assist people around the world in learning about the United States and the areas in which the VPP is focused. These were created so that the United States could have a presence in important areas without physically being there. The areas with the VPPs do not have permanent offices and staff and are run from other embassies. Some examples of VPPs include the VPP Santa Cruz in Bolivia, the VPP Nunavut in Canada, and the VPP Chelyabinsk in Russia. There are about 50 VPPs worldwide. Special Cases Though it might sound simple that consulates are in larger tourist cities and embassies are in capital cities, this is not the case with every instance in the world. Jerusalem One such unique case is Jerusalem. Though it is the capital and largest city in Israel, no country had its embassy there until President Donald Trump decided to move the U.S. Embassy there in 2018. Instead, most of Israels embassies are in Tel Aviv because most of the international community does not recognize Jerusalem as the capital. Tel Aviv is identified as the capital because it was the temporary capital of Israel during the Arab blockade of Jerusalem in 1948. Jerusalem remains home to many consulates. Taiwan Few countries have an official embassy in Taiwan to establish representation due to the uncertainty of Taiwans political status with regard to mainland China, the Peoples Republic of China. As such, the United States, the United Kingdom, and many other countries do not recognize Taiwan as independent because it is claimed by the PRC. Instead, the United States and the United Kingdom have unofficial representative offices in Taipei that can handle matters such as issuing visas and passports, providing assistance to foreign citizens, trade, and maintaining cultural and economic relationships. The American Institute in Taiwan is the private organization representing the United States in Taiwan, and the British Trade and Cultural Office fulfills the same mission for the United Kingdom there. Kosovo Not every foreign country recognizes Kosovo as independent (as of late 2017, 114 do), and just 22 have established embassies in its capital of Pristina. There are several other consulates and other diplomatic posts in the country as well. It has 26 embassies abroad and 14 consulates. Former British Empire The member countries of the Commonwealth of Nations (mostly former British territories) do not exchange ambassadors but instead, use the office of high commissioner between member countries. Mexican Consulates Mexico is distinct in that its consulates are not all confined to large tourist cities, as is the case with the consulates of many other countries. For example, although there are consulates in the small border towns of Douglas and Nogales, Arizona, and Calexico, California, there are also many consulates in cities farther from the border, such as Omaha, Nebraska. In the United States and Canada, there are currently 57 Mexican consulates. The Mexican Embassies are located in Washington, D.C., and Ottawa. Countries Without U.S. Diplomatic Relations Though the United States has strong diplomatic ties to many foreign nations, there are four with which it does not currently work. These are Bhutan, Iran, Syria, and North Korea. For Bhutan, the two countries never established formal relations, and Syrian relations were suspended in 2012 after the war started there. However, the U.S. is able to maintain varying levels of informal contact with each of these nations by using its own embassies in nearby countries or through representation by other foreign governments. However foreign representation or diplomatic relationships occur, they are important in world politics for traveling citizens, as well as for the economic and cultural matters that result when two nations have such interactions.

Political issues Research Paper Example | Topics and Well Written Essays - 1500 words

Political issues - Research Paper Example On the other hand, the UK has its monarch acting as the head of state; however, supreme authority is not vested unto the monarch because there is a separate head of the government elected by the people who exercise political powers. Just like in the US, these leaders espouse a set of laws found in the constitution (Storey, 87). This paper discusses the different between government systems of the US and the UK, as well as other countries referring to three articles. 1. Szilagyi, Ilona Maria. "Presidential versus parliamentary systems." AARMS Vol. 8, No. 2 (2009): 307–314. Notably, the founding fathers who wrote the US constitution had the British political system to draw on; however, they avoided any form of concentrated power that resembled the monarchy because it is one of the chief things that they rebelled against. Nonetheless, there are a few similarities between the two political systems. Both the British and the US forms of government have a head of state, upper and lowe r house, and a court system. The two have constitutions that depict the rules for government as well as the rights their people have. Both political systems are democratic in nature; there are firm checks and balances in place to inhibit the power of any one branch. Both governments can be put in place and can be removed from power depending on the will of the people. The president in the US political system is the legitimate head of state elected as part of the Electoral College (Watts, 312). United Kingdom have the King or Queen as the legitimate head of state while the prime minister handles political matters and is the legitimate head of government. Officially, UK’s head of state signs off any act of parliament and delivers the Speech from the throne written by the prime minister. In most modern governments, the monarch plays the part of a ceremonial figurehead thus it is atypical for members of the royal family to directly get in the way of the country’s political process. The upper house in the US is the Senate while the UK has the House of Lords. Each state under the US system of governance, despite the size, has two senate members. Before, the governor of the state used to appoint senators but these days they get to be elected by the people to serve 6-year terms. The House of Lords is quite different. They are not elected by the people. In addition, the House of Lords appoint 792 members basing on inheritance, or their title in the Church of England (Harris, 231). They are never elected and cannot be removed from office by popular vote. Nonetheless, they serve the same purpose as the US senate (Szilagyi, 310). They debate, discuss and vote on legislation passed by the lower house in the legislative branch. The British House of Commons and the US House of Representative draw on a lot of similarities. Each house comprises representative elected by the people. Control of the lower house is given to the party that carries the most number of s eats. Under the UK system of governance, the party with majority members produces the prime minister who is then the party leader becomes the Speaker of the House. Elections are also different in the two forms of government. The prime minister under the parliamentary system can go to the crown and ask to dissolve the parliament at any given point. Thereafter, an election would follow. An election would also be eminent if the Prime Minster lost the confidence of the house. 2. Mcquire,

Enterprise Architecture and its evolution Essay Example | Topics and Well Written Essays - 500 words

Enterprise Architecture and its evolution - Essay Example n enterprise communicates with the other stakeholders regarding the future of the business in terms of the integrating various business perspectives offered by the stakeholders to the technical aspects of the business that will see advance in future (Giachetti, 2010). Enterprise Architecture caters for the relationship between the people within an organization, the processes involved, the enterprise technology and information, and how all these relates to the external business environment (Giachetti, 2010). Therefore, EA is a very important component for any business that wishes to advance and transform into an effective enterprise. It embarks on addressing the challenges that a business entity is facing and how such challenges can be overcome, through the provision of a mode of governance to implement and provide holistic solutions to the existing as well as potential future problems (Giachetti, 2010). Enterprise Architecture therefore indicates the desired future state of a business entity, while guiding the enterprise through the process of achieving its desired state. This sees a business move from its present simple system to advanced data and information structures that reinforce the business performance and competitive ability. This way, EA serves to enhance the efficiency and effectiveness of a business (Giachetti, 2010). It is through EA that business structures are centralized, while the processes and the flow of information is streamlined to incorporate timeliness and accuracy. This way, running and management of business activities becomes an easier and successful event. The greatest advantage of EA is the fact that it indicates the desired future business state and then establishes the intermediate steps that will be undertaken to as to realize this state (Giachetti, 2010). The evolution of Enterprise Architecture can be traced to the 1990s, where the need to address the issues of complex business systems arose. It is during this period that

Bible Defines Human Nature Essay Example for Free

Bible Defines Human Nature Essay According to the book of Genesis, man was created in the image of God. â€Å"God created man in his own image, in the image of God he created him; male and female he created them.† Genesis 1:27   This means that man’s nature is godly. Because our almighty God is a holy God, man is also expected to be blameless before Him. But how come sin became inevitable to human nature? Isn’t it that man by nature is greedy and self centered? Other than that, the New Testament says that all have fallen short to God’s standard. Does it mean that the bible contradict itself?                  Meanwhile, western philosophers believe in the concept to tabula rasa. It’s a thesis that says that human beings are born without an inborn personality. Human personality is just a product of pile of experiences and is influenced by his surroundings. If a man doesn’t grow up in a good environment, it follows that his nature is not that good too. In other words, man was born as innocent creature without any sense of morality. We can say that being innocent is close to being blameless. Does it mean that the idea of tabula rasa supports the famous idea taken from Genesis?   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   When we look at the Christian concept of salvation, we can conclude that the Gospel presents a clear explanation regarding this long time debate. Although the bible gives a seemingly contradicting explanation regarding the nature of human beings, still it supports each other when view it from Christian perspective.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   When we were born, we can’t deny the fact that we are innocent. Just like Adam and Eve, we don’t have any knowledge of sin. And as we look back on the book of Genesis, Adam and Eve became aware that they were naked when sin entered their life. Therefore we can conclude that our sinful nature starts when we lose our innocence.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   As we grow old, our values are being by our family, community, church and media. Other than that, our personalities were shaped by our experiences. For those people who experienced rejection, they are more likely to develop pride and insecurities. It is also inevitable for them to hold grudges and bitterness. As we look at the bible, we can see that pride and bitterness are sin. Like pride and bitterness, greed is also a product of life experiences as well as family background and community involvement.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   It means that sin is an inevitable part of life. As we grow old, they more we can acquire sin which is too far from having a godly nature. But the good news is that God made a way so that human can return to their blameless nature. He sent Jesus for us to be like his image again. Because of Jesus’ blood that was shed on the cross, we are forgiven of our sin and purified to become new creations. â€Å"Therefore, if anyone is in Christ he is a new creation. The old has gone, the new has come.†Ã‚   2 Corinthians 5:17  Ã‚   This idea of Christ’s way of salvation supports the concept of sanctification.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   But sanctification is not a one time experience for Christians. They are experiencing a lifetime of sanctification as they grow in their relationship with Christ. If experiences can cause us to sin, our experiences can also be used by God to mold our characters. Our life is a preparation of our character, a way of sanctification until we meet Christ. It is the reason why the bible always compares Christ and church relationship with that of a groom and a bride. Bibliography The Bible League. The Devotional Study Bible.

Like Danielle, many young adults, and teenagers, have sex without attachment. For example, more than half of 11th-graders surveyed by the Bowling Green State University, in Ohio, said they have had intercourse, and of them a 60 percent did it with an acquaintance, they survey said. That number may have been higher if the survey had included oral sex, said the university. For many teenagers having sex with acquaintances it is their first experience.

Plato’s Republic Three Parts of the Soul Essay

In his book The Republic, Plato searches for justice within the individual and what makes a person just. By comparing his sense of what is just at a political level and what is just at a psychological level he proposes three virtues of the individual which will make that particular person just. The virtues are of wisdom, courage and moderation. A just man won’t differ at all from a just city in respect to the form of justice; rather he’ll be like the city (Republic 435b). Once Plato has found justice within the city he seeks to transfer it back into the human soul. Plato talks about the ability of a person to be indecisive about actions such as drinking when something in their soul forbids them to do so even if they desire it. This indecisiveness can be transformed into internal conflict between more than one part of the soul. One part of the soul is the rational part and the part that lusts, hungers, thirsts and gets excited is the appetitive part (439d). Plato then identifies a third part of the soul, the spirited part, which is used to create emotions. Appetite is a really big part of our souls. It contains both necessary desires, which should be indulged (such as the desire to eat enough to stay alive) and unnecessary desires, which should be limited (such as the desire to eat your entire birthday cake). Though the appetite lusts after many things, Plato says it’s money-loving, since money is required for satisfying most of these desires. It is therefore obvious to Plato that the rational part of the soul should rule, as the rulers in the city do, because they both display the virtue of wisdom and can therefore exercise foresight on behalf of the entire soul. 441e) Similarly, just as the guardians assist the rulers in maintaining justice within the city, the spirited part of the soul will use emotions in order to maintain order and harmony within the soul which is justice. These two parts of the soul will be able to control its appetitive part, which may, through its insatiable desire for money, attempt to overthrow its particular role and rule over the body and even tually the classes that it is not naturally suited to rule over (442a). Consequently, justice in the individual and justice in the city would be overturned leading to chaos and war. The rulers and guardians exist in order to control and direct the producers who are the majority of the population, as the rational and spirited parts of the soul rule the desires of the individual. Therefore a just person would be one with a spirited part of the soul that would persevere through pleasures and pains in order to carry out the rational part’s intentions on what should be feared and what should not (442b). This ability is identifiable as the virtue of courage, which is evident in the guardians. Moreover, this pattern of parallel virtues between the city and the soul continues as a person’s reason is most able to make decisions about what is advantageous for each part and for the whole soul when he/she has the knowledge associated with wisdom. As a result the desires should be kept in a state of moderation by the rational part of the soul so that the ruler and the ruled both agree that the rational part should rule and not engage in civil war (442c). In conclusion, justice in the individual is similar to justice within the city where a person puts himself in order, is his own friend, and harmonizes the three parts of himself like three limiting notes in a musical scale (443d). In the city, justice is obtained by the three parts of society each fulfilling their role as best they can, and displaying the same three virtues of wisdom, courage and moderation. This leads to a harmony between the parts, the best possible combination, which is described as justice by Plato both within the city and within the soul. This should be obvious as; after all, a city is made up of many individuals. The harmonious or rightly ordered soul, then, is one which practices the virtues of each part. The virtue of the appetites is moderation; the virtue of the spirit is courage; the virtue of the intellect is wisdom. Through these virtues the human soul attains a certain concord or integrity, which Plato understood as the only real happiness worthy of the name. The overall purpose of the Republic is for Plato to understand what makes people happy. He discovers this through the process of dividing the soul up and seeing how they work together. Ultimately, if you live a just life you live a life of wisdom and your rational side comes first. If you live an unjust life you live your life by honor, victory, or money. Most men and women living unjust lives have a one-track mind. They forget their other priorities and doing what’s right just so they get what they want. Just people always beat and unjust person and live a happier and fuller life. His separation of the soul is very simplistic altogether. However, his individual ideas were very complex. Plato wanted us to to think for ourselves to discover how we decide to arrange our parts of the soul.
