Obesity, Diabetes And Lung Cancer - 1046 Words

Epidemiological studies: Critical Review of Obesity, Diabetes and Lung Cancer Epidemiological Study on Obesity The overweight problem is big issue in the United States and worldwide with the average American weighing 3-5 kilograms more than they did ten years ago. Obesity is an excess of body fat that leads to ill health. The study was based on a sample representative of United States where 22.9 percent men and 23.3 women were obese, and 44.1percent of men and 34 percent of women were overweight indicating that almost half of the United States population was overweight. The research covered children aged 6-11 years and the prevalence rate was 15.8 percent in 2007 with a higher prevalence among Black male and female’s at 20 percent and Hispanics at 26.5 with Whites recording the lowest at13.5 percent (World Health Organization, 2007). Adiposity is the balance between energy intake and expenditure. Excessive intake of energy rich food is one of the main contributors to obesity. The other cause is the sedentary lifestyle that most United States citizens expose themselves to with the younger generation spending more time on the couch either watching television, playing games or on the computer. This lack of exercise is a contributory factor of obesity (Cole, 2000). The other factor is the modern day preference for food rich in energy and fats from the traditional lean meals. Low sugar and a high fat diet are more prone to cause obesity than high sugar low fat diet.

Human Sexuality - 2732 Words

Human Sexuality By Ludwin Molina Spring, 1999 Introduction Human sexuality plays a major role in everyones life. Regardless, whether we are young or old, man or woman, American or Japanese, it is an integral part of what we do and who we are. There has been much done by way of research and scholarly writing examining human sexuality (e.g., Abramson Pinkerton, 1995; Beach, 1976; Diamond, 1997; Reinisch et al., 1990; Stalcup, 1995; Tiefer, 1995). This paper will explore the topic of human sexuality as a motivation. Of course, there are many emotions associated with human sexuality, but the primary aim of this particular paper will be a general overview of sexuality with special attention to the various perspectives, including the:†¦show more content†¦In other words, the participants behavior may consciously be changed to fit with what they believe the observer is seeking. Human Sexual Response (1966) by William Masters and Virginia Johnson is one of the seminal studies examining the sexual behavior of humans via the observation method. Despite the controversy engendered by the method of their study, it gave a reliable picture of what happens to the body during sexual behavior. Experimental Method. Experiments permit researchers to draw causal conclusions between the independent variable and dependent variable. One example of this method is exposing participants to sexually arousing materials while instruments monitor physiological responses (Katchadourian, 1989). The particular limitations of this study seem obvious, in that, one cannot manipulate many variables of interest directly because of ethical standards. Correlational Method. Allows the researcher to examine the relationship between variables of interest. For example, a researcher may be interested in the variables that relate to sexual satisfaction in couples. Therefore, he/she may look at the variables of partner compatibility, communication skills, and number of years the couple has been together. The major limitation of this method is that correlation does not equal causation. Case Study Method. The intensive study of one particular participant.

Solar Energy free essay sample

A new solar powered adsorption refrigerator with high performance Meunier published a comparison of those three sorption systems for solar cooling (Meunier, 1994). The solid–gas system used in the present study is adsorption. The solar adsorption refrigerators have been developed mainly to be used in hot regions with no electricity supply. There is an urgent need in the health sector (for the conservation of medicines and vaccines). These systems have the advantage of not requiring any energy other than solar energy.

Regarding performance, the highest values of COPSR (0. 10–0. 12) were obtained with the adsorption systems zeolite + water (Grenier et al. , 1988) and activated carbon + methanol (Boubakri et al. , 1992a,b; Pons and Grenier, 1987). As methanol can easily evaporate at temperatures below 0 Â °C, thus favouring the production of ice, the most environmentally friendly refrigerant must be water. Using water, ice can be produced within the evaporator, acting as a ‘cold storage’. Both refrigerants, water or methanol, operate at below atmospheric pressure and therefore require vacuum technology. The main purpose of the present study is to obtain better performances than those reported above, with what is, technically speaking, a simple machine. This aim seems reasonably achievable with an adsorptive machine, operated in a 100% solar-powered 24 h cycle with a ? at-plate solar collector containing the adsorbent. However, when referring to the work reported above, both the e? ciency of the solar collector and that of the adsorption thermodynamic cycle could be improved. These requirements were crucial to the design of the ‘advanced’ machine. The laboratory of solar energy of the Engineering school of the Canton de Vaud (EIVD, Yverdon-lesBains, Switzerland) has been developing adsorptive solar refrigerators since 1999. The ? rst systems built used the adsorption pair of activated carbon + methanol. For reasons of reliability and respect for the environment, this pair has been abandoned in favour of a silicagel + water pair. The prototype described and analyzed in this paper has been functioning since the summer of 2000 on the site of the EIVD. A thorough measurement system allows us to characterise it in a complete way. During the summer of 2001, a constant procedure of thermal load in the cold cabinet allowed us to observe the behaviour of the adsorption system over a continuous period of 68 days. We have highlighted the great in? uence of both external temperature and daily irradiation upon the daily coe? cient of performance (COPSR ). Previously, few articles were interested in the analysis of the storage. 2. Description of adsorption and of the adsorption cooling cycle Adsorption, also known as physisorption, is the process by which molecules of a ? uid are ? xed on the walls of a solid material. The adsorbed molecules undergo no chemical reaction but simply lose energy when being ? xed: adsorption, the phase change from ? uid to adsorbate (adsorbed phase) is exothermic. Moreover this process is reversible. In the following, we will focus on adsorption systems mainly used in cooling (or heatpumping) machines: a pure refrigerant vapour that can easily be condensed at ambient temperature and a microporous adsorbent with a large adsorption capacity. The main components of an adsorptive cooling machine are the adsorber (in the present case, the solar collector itself), the condenser, the evaporator and a throttling valve between the last two devices, see Fig. 2. An ideal cycle is presented in the Dâ‚ ¬hring diagram (LnP u vs. A1=T ), Fig. 1. The cycle is explained in detail in (Buchter et al. , 2001). We can summarize it in four stages. C.

Description of the machine tested in Yverdon-les-Bains, Switzerland Adsorptive pair. The refrigerant is water, and the adsorbent is a microporous silicagel (Actigel SGa , Silgelac). Collector–adsorber. The solar collector (2 m2 , tilt angle of 30Â °) is double-glazed: a Te? ona ? lm is installed between the glass and the adsorber itself. The adsorber consists of 12 parallel tubes (72. 5 mm in diameter) that contain the silicagel (78. 8 kg). The tubes are covered with an electrolytic selective layer (Chrome-black, Energie Solaire SA), which absorbs 95% of the visible solar radiation while presenting an emissivity of 0. 07 in the infrared wave-lengths. The tubes are layered with a material which presents high conductivity but low speci? c heat capacity (sheets of graphite: Papyexa , Le Carbone Lorraine). A central tube is made out of a grid (diameter 15 mm, mesh 1 mm, wire 0. 45 mm diameter). The ventilation dampers mentioned in the previous sections consist of a Fig. 2. Photograph and plan of an adsorptive solar refrigerator: solar collector–adsorber (1) with detail: glass cover (A), Te? ona ? lm (B), tube covered with selective surface (C) and internally layered with Papyexa , central tube for vapour transport (D), silicagel bed (E), thermal insulation around the collector (F); ventilation dampers (2) closed (2a) and open (2b), condenser(3), cold cabinet (4), graduated tank (5), valve (6), evaporator and ice storage (7). mechanism that allows the thermal insulation to be opened on the rear side of the collector (50 mm glass ?bre), to provide e? cient cooling by natural convection during the night. Condenser. Eight parallel ? nned tubes make a condenser, and are cooled by natural convection of air. The total ? n area is 6. 9 m2 . Evaporator, ice storage and cold cabinet. The evaporator consists of three rings made of square tubes. The total heat exchange area is 3. 4 m2 The evaporator contains 40 l of water which can be transformed into ice during the evaporation stage. The cold cabinet is chesttype and is well insulated (170 mm of expanded polystyrene) with an internal volume of 320 l. 314 C. Hildbrand et al. / Solar Energy 77 (2004) 311–318 Valve. A valve located between the graduated tank and the evaporator is needed on this machine. For control strategy reasons, this valve is electrically powered. 4. 5. Ventilation damper management Closing: when the irradiance goes above 100 W/m2 . Opening: at the end of the afternoon when the angle of the solar beam radiation incident upon the aperture plane of collector (angle of incidence) is above 50Â °. 4. Measurements and operations The objective of the 2001 series of measurements was to obtain a high number of measurements continuously, in order to characterise the working of our adsorption machine. To do this, a system of measurement and a constant procedure of load has been established. 4. 1. Measurements The temperature is measured (probes Pt100) in the silicagel of a central tube of the collector–adsorber (7 sensors), on two condenser tubes and three evaporator tubes; and the ambient air temperature is also measured. The vapour pressure is measured by a piezogauge in the collector-adsorber, in the condenser and in the evaporator. The global irradiance in the plane of the collector is recorded by a pyranometer. A graduated tank (6. 5 l) collects the condensed water. The level of liquid water is automatically measured by a level detector. 5. Meteorological conditions The series of measurements took place from July 25th to September 30th 2001 (68 days) in Yverdon-lesBains (altitude: 433 m, longitude: )6. 38Â °, latitude: 46. 47Â °). Fig. 3 shows the observed weather conditions (daily irradiation and mean external temperature). This graph shows two di? erent periods: (1) From July 25th to the beginning of September: during this summer period, the mean external temperature is above 20 Â °C and the mean daily irradiation reaches 22 MJ/m2 . This ? ne weather period is interrupted between the 3rd and 9th August by less favourable weather. (2) From the beginning of September to the end of the measurement: the mean external temperature and the daily irradiation are distinctly lower (13 Â °C and 13 MJ/m2 ). Furthermore, the conditions are very variable from one day to the next. 4. 2. Acquisition system and command 6. Performance of the tested unit A Labviewa program takes measurements and administers various commands (valve, dampers and load). A measurement is made every 30 s. For each day, a gross solar COPSR can be de? ned as the ratio of the heat extracted by evaporation of water to the solar heat supply, see equation (1). The ? rst one, Qe , is obtained by multiplying the mass of processed water, mL , by the enthalpy di? erence between the saturated vapour at Te and the saturated liquid at Tc The second one, Qh , is the product of the surface A of collector and the solar irradiation obtained by integrating the solar irradiance G from sunrise to sunset.

venonous snakes Essay Example For Students

venonous snakes Essay It all started about five years ago when my brother had gotten me a job at the zoo. My whole life I had never really been interested in snakes, I had always thought that they were useless and served no interest to me what so ever. My entire life I had always had a love for animals and wanted to go to vet nary school so I could always be around animals, so Harold had given me a chance to become a zoo keeper. I worked at the Scotch Plains Zoo for three and a half years before it was closed down do to lack of money. While I had worked there I had become to love snakes and thought that were amazing creatures. This love grew to where I started taking in snakes that people didnt want as pets anymore so I would care for them. I started out with two constrictors one blood python and one red tailed boa. I still have both of these snake today the python is 7ft and ninety pounds and the boa is 5 feet and about fifty pounds. We will write a custom essay on venonous snakes specifically for you for only $16.38 $13.9/page Order now At first my parents were going to have a heart attack but they accept it now. While I was working at the zoo I applied to take the test for caring for exotic and endangered animals. It had taken forever to get my permits and even with them it is still hard to purchase a lot of animals. When I moved out of my house and got my own place I wanted to start a breeding program for venomous snakes for other zoos in the country. I dont sell my snakes to them I just donate them so other people can see and learn from them that they are not Satans creatures and are quite docile. The first snake that I had purchased was a horned pit viper (which had taken me about 5 months to get. I had to hand build all my enclosures due to the fact that each snake needs different humidity, light and enclosure space. As time gone by I had gotten two more breeding pairs one russels viper and one death adder. The two vipers have a high potency of venom but nothing like the death adder, plus the death adder has one nasty attitude problem. The death adder is the third most venous snake in the world and if it did bite me I would only have 10 minutes to inject myself wit the anti-venom or I would be dead, and even with the anti serum I would still be hospitalized for some time. At my house I keep all three pairs of snakes in the basement all in separate enclosures. I can only put the males and females together at mating season or they could fight(snakes can sometimes be cannibals). It is funny when my roommates come home even to this day they check every night that each snake is in its cage( I guess I cant blame them though ) but they have accepted it and are starting to get use to it. In the future I plan to get one more breeding pair I am just no sure which ones I want yet. Over the past year I have gotten calls from several zoos that asked if they could have the hatchlings. So far you can see my snakes at the Poconos game far, Bronx Zoo, LA zoo, Columbus Zoo, and The South Carolina Alligator Farm. I do what I do not for the purpose of having venomous snakes but to show others that you dont really have much to fear from snakes unless you provoke them. People like I was are afraid of something that they shouldnt be, a snake is not going to come and attack you but more of the less try to get away from you as fast as they can. I think that everyone that is afraid of snakes should hold one just one time to realize that there is really nothing to fear but I also do not mean to go out there and pick up a venomous snake that would be stupid, but to go out and conquer there fears.
