THE EFFECTS OF ALTITUDE ON HUMAN PHYSIOLOGY Essays - Oxygen

THE EFFECTS OF ALTITUDE ON HUMAN PHYSIOLOGY Essays - Oxygen 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 will constitute 20% of the total atmospheric pressure

Write About What You Know

Write About What You Know Write About What You Know Write About What You Know By Michael For thirty years, the mid-term exam for Dr. McAnellys Biblical Literature class was always the same essay question: Describe the wandering journeys of the Apostle Paul. So a college football fullback and his roommate decided they wouldnt study anything else, thereby leaving them more time for other attractive pursuits. Imagine their surprise when the question instead was, Critique the major themes of Jesus Sermon on the Mount. Now, imagine the fullbacks surprise when his roommate nevertheless began to write furiously for the next hour. The fullback stared at his blank test paper for a long time before giving up and leaving the room, but his curiosity was so strong that he peeked at his roommates essay as he walked past. The first sentence read, Who am I to critique the words of the Lord Jesus? Let me rather describe the wandering journeys of the Apostle Paul. Seasoned authors advise, Write about what you know. In fact, you have to write about what you know. Try to write about what you dont know, about which you havent got a clue, and youll be staring at a blank piece of paper for a long time. Its one of the surest ways to contract writers block. If you succeed in actually getting words onto the page, your readers will be staring at it for a long time, trying to figure out what you just said, if not why you wrote it in the first place. Why would anybody write about what they dont know? Why would people do something like that? Because someone important told them to. Essay tests in school are a good example. Your instructor asks you to write about one of the (several) chapters in the textbook that you never got around to studying. Your job, should you choose to accept it, is to employ your literary skills to make your instructor believe that you read and understood the chapter. Changing the question rarely works. Because what they dont know seems more interesting than what they do know. Young writers frequently make that mistake. When you move into the cloud of unknowing to write your piece, youre increasing your competition. In the mid-60s, without having any personal experience with them, lots of American teenagers were probably writing about monsters and spaceships, though these markets were already fully stocked with experienced grown-up writers. None of them wrote about being a real American teenager except S.E. Hinton. So her book The Outsiders got published and their books didnt. Because they value style over communication. Poets sometimes make this mistake. They write about the universal life force, instead of about a tree. Down-to-earth, brass-tacks writing doesnt seem stylish enough. But uninformed writing is less interesting than informed writing. The details which make writing vivid and readable are missing, like a price tag in a store, or somehow off, like a carton of old milk. Writing about what you know is a cure for writers block. Thats one reason why journaling or blogging is so popular among writers. Something must have happened to you today, unless you were dead. Write about it. It didnt happen to anyone else, unless youre a clone. Nobody has the same brain or biography as you, so nobody has the same perspective as you. If they do, I suggest you get your own perspective. You need your own. Dont try to share with your neighbor. Thats cheating. Want to improve your English in five minutes a day?

International Business Essay Example | Topics and Well Written Essays - 750 words - 6

International Business - Essay Example The demands and supply in the international market determines the exchange rate of world major currencies. The supply of a nation currency reflects demands for foreign goods services and securities by that country. The demand of a currency of a country reflects foreign demand for that country goods, services and securities from other countries. Ceteris Paribus, the quantity demanded reflects a negative function of the exchange rate. The market gravitates to equilibrium exchange rate where quantity demanded is equal to the quantity supplied. For instance, Ceteris Paribus, from initial equilibrium, if U.S incomes, inflations or foreign interests’ rates rise, U.S demand for foreign goods, services and securities will increase and so will the supply of dollar. The market will gravitate to the new equilibrium at a lower exchange rate that corresponds to the depreciation of the dollar (Bigman and Teizo 2003, p. 88). Similarly, Ceteris Paribus, if foreign incomes, foreign inflations, or U.S interest rates rise, foreign demands for U.S goods, services and securities will rise and so will be the demand for the dollar. The market will gravitate to a new equilibrium at a higher exchange rate that corresponds to an appreciation of the dollar. ... However, it is worth to note that market forces are not the only factors that influence the exchange rate. In addition, Central Bank may intervene in the foreign exchange market selling or buying currencies to impact the exchange rates. Central bank intervenes when the currency becomes either over or under valued. This system is distinctively different from the fixed exchange rate system under the Breton woods accord. Therefore, it is interesting to note that the present international monetary system can be characterized more correctly as a managed float exchange rate system. This is because the exchange rates changes according to demand and supply, however, central bank may intervene when deemed necessary to save the currency (Burton 2009, p.436). Opponent of Floating exchange rate system argues that’s the system leads to exchange rate volatility which consequently affects trade. Analysis of the effect of exchange rate volatility on trade can be grouped into two. There are th ose who use time series evidence to look at the relationship between volatility and trade, and there are those who use cross- sectional comparison across countries. Results on different studies relating to effect of exchange rate volatility and trade using the time series evidence varies quite widely a few have found a significant effect but most finds little or no impact, for instances surveys done by IMF in 1984 and the Commission for European Communities in 1990. This research indicates that higher volatility has a small negative impact on trade volumes (Burton 2009, p.438). Alternatively, comparisons can be made across countries rather than over time. A model of expected trade flows between countries calculates

Shear Testing in Made Ground Essay Example | Topics and Well Written Essays - 3000 words

Shear Testing in Made Ground - Essay Example otechnicians and construction firms to determine the usability of Made Ground through the estimation of its strength and necessary properties (Bouazza et al., 1997). Made ground can be easily found all around us: they could be in the form of sandy, silt, clay and loamy soil (Bouazza et al., 1997). Shear Testing is a standardized laboratory test that has been used to detect the mechanical properties of Made ground, most especially its tensile strength (Woodward, 2005). Such a test is helpful in determining the usability of the ground and outlining the soil’s harmful contents that may make construction works on the ground impossible. In this case, serious consideration is given to the environmental impact of soil properties: how does the environment is affected by the constituents of a soil? Are there some harmful objects in the soil, for instance in brownfield and other abandoned property? (Geltman, 2000). Shear Testing of Made Ground can be simply carried out by using the Direct Shear Test (Das, 2008). Information about the standard reference, test expectations, equipment, test procedures, test data and analysis are provided as follows: Being the commonest method of discovering the tensile strength of soils, Direct Shear Test could help to estimate the angle of internal friction (Hillel, 1998). When plotting the shear stress against the horizontal displacement, the maximum, shear stress can be obtained. Therefore, after carrying out several vertical-confining stresses, it is possible to plot the maximum shear stress against the vertical confining stresses for each of the tests produced. Then a straight-line approximation of Mohr-Coulomb failure envelope curve could be drawn (Parry, 1995). And the shear strength of the soils under investigation could be estimated using the formula below: ix. I started the motor with chosen speed so that the rate of shearing is at a selected constant rate, and take the horizontal displacement gauge, vertical displacement gauge

ATR-FTIR Analysis for Oil Type Identification

ATR-FTIR Analysis for Oil Type Identification Abstract Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy (ATR-FTIR) analysis could greatly help in the identification of oil. By mere inspection of the IR spectra, saturated oils can be easily distinguished from coconut oils. Identification of oils can be enhance by the use of chemometrical techniques such Principal Component Analysis (PCA). Using this technique, subtle differences in the spectra can be used to classify vegetable oils. This study have shown that ATR-FTIR together with PCA can be used to differentiate unsaturated oils from saturated oil and discriminate virgin coconut oil (VCO) from ordinary refined, bleached and deodorized coconut oil (CCO). Introduction Virgin coconut oil (VCO) has a potential to be one of the Philippines’ high-value export products. In the first half of 2005 alone about 350 metric tons of VCO were shipped to foreign markets. Virgin coconut oil is a minimally process or a cold press oil obtained by mechanical means (Philippine National Standard for Virgin Coconut Oil 2005) such as crushing pressing and centrifugation. These procedures result in the retention of the natural flavor and minor components of the oil, which can otherwise be destroyed by chemical process such as refining, deodorizing and bleaching. Cold pressed oils commands a higher price compared to processed oils because these â€Å"natural† procedures deliver lower yield and uses higher quality raw materials to prevent spoilage (Ulberth and Buchgraber 2000). To ensure the quality of VCO in the country, The Philippine National Standard provided a criterion (PNS/BAFPS 22:2004). This standard includes determination of fatty acid composition using gas-liquid chromatography (GLC), iodine value and sensory parameters such as taste, odor and color (Philippine National Standard for Virgin Coconut Oil 2005). However, it is a known fact that the fatty acid profile of oils is species dependent; therefore this classification method cannot distinguish VCO from ordinary refined, bleached and deodorized coconut oil (CCO). Iodine value in the other hand gives information on the degree of unsaturation of the oil and may be use only to distinguish coconut oils from unsaturated oil like corn oil (CO) and soybean oil (SO) but cannot discriminate VCO from CCO. Sensory parameters can easily be manipulated by bleaching and deodorizing the oil or by addition of flavoring agents. In recent years, various spectroscopic methods have been employed to authenticate vegetable oils such as virgin olive oil (VOO) (Aparicio and Luna 2002; Bucci et al. 2002; Dupuy et al. 1996; Lankmayr et al. 2004; Ozen et al. 2003; Tapp et al. 2003; Tay et al. 2002; Vigli et al. 2003; Yang et al. 2005). These techniques have the advantages of minimal sample preparation and rapid analysis time (Ulberth and Buchgraber 2000). In the study conducted by Yang et al (2005), Fourier Transform Infrared (FTIR) spectroscopy was found to be the most efficient in classification of oils as compared to Fourier Transform Raman and Fourier Transform Near Infrared spectroscopy. An attenuated total reflectance (ATR) accessory is usually used with the FTIR spectrometer for oil and fat study due to its ability to handle liquid samples easily. The resulting infrared spectrum contains all vibrational information about the entire components of the sample. In order to take full advantage of the spectral infor mation, including subtle features that may not be readily discerned, pattern recognition techniques such as Principal Component Analysis (PCA) are commonly used. These techniques can reveal relationships that were not previously suspected, which can lead to interpretations that are not readily apparent by mere visual inspection of IR spectra alone (Beebe et al. 1998; Davies and Fearn 2005). PCA is a mathematical manipulation used to reorganize the high-dimensionality of spectroscopic data into a smaller number of â€Å"Principal Components† or PCs that can account for the majority of the information in the data set. Methodology All samples of edible oils were obtained from reputable supermarkets in Iloilo City. Samples include four brands of VCO [a total of six samples, one brand have a total of three samples, two regular VCO with different manufacturing dates (labeled as VCO2 and VCO3) and one corn flavored VCO (labeled as VCO4) ] , three different brands of coconut oil ( CCO1, CCO2, and CCO3) and one brand each of corn oil (CO), soybean oil (SO), canola oil (CLO), virgin olive oil (VOO) and palm oil (PO). The oils were stored in their original containers until used. Minimal opening of bottles were observed to prevent oxidation of oils. Infrared (IR) spectra of samples were obtained at 4000 – 400 cm-1, 1 cm-1 resolution and 64 scans; using the Avatar 330 Thermo Nicolet FTIR equipped with DTGS (deuterated tri-glycine sulphate) detector and EZ OMNIC software at the University of the Philippines in the Visayas Chemistry Laboratory, Miag-ao, Iloilo. Samples were placed directly on a multi-bounce zinc selenide horizontal ATR crystal. The ATR crystal was totally cleaned using acetone after each run. IR spectral data of different oils from EZ OMNIC software were converted to Microsoft Excel files. Data were arranged in tabular form, different oils in columns and transmittance at different wavelengths in rows. The excel file was then transferred to Unscrambler version 9.6 for Principal Components Analysis. The evaluation version of this software can be downloaded at www.camo.com. Results and Discussion The FTIR spectra of most fats and oils appeared almost visually similar; the slight differences in the spectral features reflect the variations in the fatty acid composition (Figure1 to 6). Every peak in the spectra represents structural and functional group, either of the oil or other minor components. At the high frequency end of the spectrum (4000-3500 cm-1) only a few absorption bands can be observed. The most notable are the absorption bands due to O-H stretching vibration at about 3700 and 3400 cm-1, which may be due to moisture, alcohol or fatty acids. Both alcohols and free fatty acids are degradation product of triglycerides which accumulate during prolong storage and in the presence of moisture. For a clean and dry oil, only the first overtone of the C=O vibration could be seen. The strong band dominating the 3000-2840 cm-1 region is due to C-H stretches of methylene and terminal methyl groups. The =C-H stretch absorbed at slightly higher region, 3095 -3010 cm-1. A strong a bsorption peak in the range of 1750-1735 cm-1 is due to the C=O stretch of an aliphatic ester. If degradation has occurred a shoulder located on the lower frequency side of this will appear due to the C=O stretch of the resulting long chain carboxylic acid (1730-1700 cm-1). A sharp peak at about 1660-1600 cm-1 results from a C=C stretching vibration. The presence of this peak together with a C-H peak at wavenumber greater than 3000 cm-1 is a good indication of unsaturation. The part of the spectrum lower than 1500 cm-1 is called the fingerprint region. The absorption in this area of the spectrum is highly characteristic of the molecule as a whole, and can be used to identify the substance (Pavia et al. 2000; van de Voort et al. 2001). As shown in Figure1-6 its is easy to distinguish unsaturated oils from saturated oils by observing the regions that indicate unsaturation, 3095-3010 cm-1 and 1660-1600 cm-1. For olive, corn, palm, canola and soybean oil sharp peaks are seen in both of these areas but no such peaks can be seen in the IR spectra of either CCO or VCO. Thus, visual examination of the IR spectrum can provide a way to distinguish unsaturated oils from coconut oils. However, visual inspection of the spectra alone is insufficient to differentiate VCO from CCO because their IR spectra are identical to the naked eye. To compare such large data sets like IR spectra, which consist of more than a thousand wavelengths, Principal Component Analysis can be used. This chemometrical technique mathematically models the data into a more manageable data sets (consisting of a few principal components) that can then be interpreted more easily (Brereton 2003). Principal Component Analyses were performed on the spectra of all oils using Unscrambler version 9.6 software. The software generated several important plots. The percent variance plot gives the total variation in the data set that is described by a particular PC. This plot can be used to determine the number of PC that can effectively describe the whole data set. The 2D scatter plot (PCy vs. PCx) represents how the samples are related to each other. The closeness of the samples in the plot is interpreted as chemical similarity(Beebe and others 1998). The percent variance plot (Figure 7) of the oil samples spectra generated by the software shows that the first two principal components represent almost 100% of the variance in the data set. As a general rule the PCs that account for less than 5% of the data variation can be rejected (Beebe and others 1998), therefore the first two PCs are sufficient in making our investigation. The scatter plot of first principal component (PC1) versus the second principal component (PC2) shows that it possible to separate the oils into two separate groups, the unsaturated and coconut oil group (Figure 8). Unsaturated oil group consists of corn oil, soya oil, canola oil, palm oil while that of the coconut oil includes CVO and CCO. Performing the same analysis on CCO and VCO spectra reveals that only the PC1 and the PC2 are highly significant (Figure 9). However, the scatter plot of the two PCs did not successfully separate VCO from CCO (Figure 10). Close inspection of spectra reveal that there are absorption bands at the high frequency region that might indicate the presence of moisture, fatty alcohol or fatty acids in some samples. This observation is confirmed by the Influence Plot (Figure 11) that shows that there is a high residual variance of the 3740 cm-1, a wavenumber corresponding to H-O absorption. This indicates that the moisture content, fatty alcohol or the free fatty acid content of the oil may have greatly controlled the classification process. The other residual in the influence plot may be due to other components of VCO or CCO that are vital in the classification process. To correct for the effect of the O-H absorption band, it was decided to eliminate wavelength above 1800 cm-1 from the spectra of the oil and use only the area encompassing the carbonyl carbon (C=O) and fingerprint region, 1800-400 cm-1. Principal component analysis of this part of the spectra shows that the first two PC can be used to correctly classify VCO and CCO into separate groups (Figure 12 and 13). In conclusion, FTIR identification of oils can be enhance by the use of chemometrical techniques such Principal Component Analysis. Using this technique, subtle differences in the spectra can be used to classify oil. FTIR together with PCA can differentiate unsaturated oils from saturated oil and can discriminate virgin coconut oil from ordinary refined, bleached and deodorized coconut oil (CCO).

My Reflection of Ethics

A great philosopher of Ethics is Aristotle. His theory was originally introduced in ancient Greek times. Aristotle was a great believer in virtues and the meaning of virtue to him meant being able to fulfill one's functions. Some base ethics on pure reason, while others ground ethics in feelings or intuitions. Aristotle says that those who do lead a virtuous life are very happy and have sense of well-being. Happiness is the ultimate goal for everyone in life. Utilitarian’s believe ethics becomes a matter of calculating how to produce the greatest balance of pleasure over suffering.To become a better person, we must practice virtuous acts regularly. After a while, these acts will become a habit and so the virtuous acts part of our every day life and the person will be leading a virtuous life. For example, if a singer practices singing everyday, they will become better at it and used to doing it. People who practice their virtues improve their skills and therefore becoming happi er. When a person learns how to use the virtues, they become the characteristic of the person. For example, a person who has learned the virtue of generosity is often called a generous person because he or she is generous in all situations.Aristotle says we are most likely to acquire virtues by observing others in our society. If we experience other people being kind to us and see the happiness it creates we are more likely to practice this virtue then if we were just told to practice it. Social contract theorists believe ethical principals are made, not found. They also believe ethics are constructed by social groups, and exists for the benefit of those groups. Social contract theory is an examination of the justice and fairness of political and social and ethical systems.An example of this would be that I would never accept a rule that says, ‘women should have less opportunity to become president, or that African Americans should have less chance of going to college or be re stricted in the places they can live’. I wouldn’t accept such rules, because there’s a chance that I might step out from behind the ‘veil of ignorance’ and discover that I am an African-American woman. So I would favor setting up a society in which everyone has equal opportunity to compete for everything. Social contract theory forges an ethical system with no help from God or â€Å"natural law† or transcendent truths or powers of intuition.Egoism comes in two varieties. First is psychological egoism: the view that-as a matter of empirical psychological fact-all our behavior is selfish, or self-interested. Second is ethical egoism, which is the very different claim that we ought to always act in a way that is self-interested. If the claim is that everyone pursuing their own selfish interest will result in the greatest benefit for everyone, it is difficult to find any empirical grounds-biological, economic, or otherwise-for that universal egoi stic article of faith. Ethical relativism is the thesis that what is right is relative to each culture.Virtues in one country or society may not be the same as virtues in another. As virtues have evolved through society it is possible that good actions may be perceived as bad actions in another society. However the virtues stay the same in every community as well as the ultimate aim which is supreme happiness. Aristotle explains that all actions are done in order to reach an aim or goal. A series of actions are also leading towards an aim, for example getting up in to morning to go to work, leads to making money, leads to feeding our families, leads to going on holidays, etc.The utmost ultimate aim is to make people happy; everything is subordinate to the supreme good, which is happiness. Relative morality is based on the theory that truth and rightness is different for different people or cultures. Moral relativism states that morality is dependent on the society. It states that th ere are no moral absolutes and that there is no definite right or wrong. In some societies certain behavior is seen as morally right whereas in others the same behavior is not acceptable. To be a relativist is to accept this principle and not to judge others for their behavior.Moral relativists accept that whether a moral code exists because of tradition or religion, it may be needed to keep the society together. Some people may argue that any moral code is better than no moral code however the absence of moral rules would be disastrous for any society, it would not survive. People need set rules or moral codes to live by in order to make the right decisions and to keep society together in the long run. Without a set moral code everyone would have the opinion that their ideas and thinking is right; no one would be able to compromise.It would be much easier for everyone to be living under the same ‘rules'. This way people will know what is right and wrong without any disagreeme nts. Care ethics does not ignore or disparage reason, but it does emphasize the importance of empathy and affection, friendships and relationships: elements of ethics (from the perspective of care ethics) Kantian systems woefully neglect. Care ethics also diverges significantly from the impersonal calculations of utilitarianism. Another distinctive feature of care ethics is on certain views, our duties tend to be impersonal.We have duties and obligations to others, of course, but they are duties due to anyone in the same position. On the care view, we may also have impersonal duties, but at least as important are duties of a very personal and individual nature: duties we owe specifically to family and friends, are not to just any generic moral placeholder. These duties are owed not because we are reciprocating benefits we have received but because of our special relations. Furthermore, such duties are typically not based on choices or voluntary contracts.
