The Social Factors of College Lifestyle that may Cause Weight Gain in Undergraduate Students
The college life is a one of a kind experience. It is usually the first time students move away from their families and become independent. It is also a time for experimentation. Many students begin to figure out who they are by getting involved in school activities, and meeting new people. It is important to make friends and meet new people in college, and for many this is done by partying at night. College is a time of change: many begin to pick up habits, such as drinking, to deal with the change. This time of change includes social problems as well as academic, problems, which can be very stressful and tough for students to manage. As a result of these changes; body weight, dietary habits and overall fitness start to change, in many cases spiraling downward.
Studies have been done focusing on college students and weight gain. In this paper I focus on the social factors of college lifestyle correlated with weight gain in college students. Weight gain is caused by poor eating choices and exercising habits, heavy drinking of alcohol and increased stress levels. It is important to study the causes of weight gain in this particular group because they contribute to the tremendous rise of obesity in the United States (CDC, 2007). Another reason this is sociologically important is because the culture of college is one like no other. College is a time of learning, growth and development. Students engage in activities that they perhaps would not have participated in before or after college. These habits that students create during the years of college may stay with them in the future. These habits tend to be created during freshman year
Rule 10b-5: The Rejection of the Birnbaum Doctrine by Eason v. General Motors Acceptance Corp. and the Need for a New Limitation on Damages
Det är viktigt att vägarna håller så länge som möjligt. En faktor som har en påverkan i asfaltens långvarighet är bitumen. När bitumenet föråldras försämras dess egenskaper som ökar risken att skador uppstår på asfalten. Med hjälp av olika tillsatser kan bitumenets egenskaper förbättras. En av dessa egenskaper är bitumenåldring. Sammanlagt finns det tre olika skeden i bitumenåldring. Av dessa tre skeden kommer tillverknings- och användningsskedet att undersökas. I detta examensarbete kommer tre olika tillsatsers påverkan i bitumenföråldring att undersökas. Detta kommer utföras genom laborationer där olika metoder som penetration, mjukpunkt, fraass brytpunkt, DSR, Iatroscan, GPC och FTIR kommer användas. Det kommer också utföras styvhetestester på de tillverkade asfaltskropparna. Resultaten som tas fram i detta examensarbete tyder på att Rediseten har bäst värden avseende åldring utav bitumen. Men detta tros inte vara på grund av tillsatsens inverkan i bitumen utan möjligheten att sänka temperaturen vid tillverkningen av asfalten.It is important that roads last as long as possible. One factor that has a prolonged effect on asphalt is bitumen. When bitumen ages the characteristics deteriorates which increases the risk for damages on the asphalt. With the help of different additives the characteristics of bitumen could improve. One of these characteristics is bitumen aging. There are three different stages in bitumen aging. Of these three stages will the production and user stage be examined. In this thesis will three additives effect on bitumen aging be examined. This will be performed by doing laboratory experiments where different methods will be used such as penetration, softening point, fraass breaking point, DSR, latroscan, GPC and FTIR. Stiffness tests will be made on the constructed asphalt bodies. Results in this thesis interprets that Rediset has the best values when it comes to aging of bitumen. It is not believed to be the additives effect in the bitumen but the fact that the additive gives the opportunity to lower the temperature during the production of the asphalt
Finite Volume Method for the Relativistic Burgers Model on a (1+1)-Dimensional de Sitter Spacetime
Several generalizations of the relativistic models of Burgers equations have
recently been established and developed on different spacetime geometries. In
this work, we take into account the de Sitter spacetime geometry, introduce our
relativistic model by a technique based on the vanishing pressure Euler
equations of relativistic compressible fluids on a (1+1)-dimensional background
and construct a second order Godunov type finite volume scheme to examine
numerical experiments within an analysis of the cosmological constant.
Numerical results demonstrate the efficiency of the method for solutions
containing shock and rarefaction waves
Design of a ROIC for scanning type HgCdTe LWIR focal plane arrays
Design of a silicon readout integrated circuit (ROIC) for LWIR HgCdTe Focal Plane is presented. ROIC incorporates time delay integration (TDI) functionality over seven elements with a supersampling rate of three, increasing SNR and
the spatial resolution. Novelty of this topology is inside TDI stage; integration of charges in TDI stage implemented in current domain by using switched current structures that reduces required area for chip and improves linearity performance. ROIC, in terms of functionality, is capable of bidirectional scan, programmable integration time and 5 gain settings at the input. Programming can be done parallel or serially with digital interface. ROIC can handle up to 3.5V dynamic range with the input stage to be direct injection (DI) type. With the load being 10pF capacitive in parallel with 1MΩ resistance, output settling time is less than 250nsec enabling the clock frequency up to 4MHz. The manufacturing technology is 0.35μm, double poly-Si, four-metal (3 metals and 1 top metal) 5V CMOS process
Realization of a ROIC for 72x4 PV-IR detectors
Silicon Readout Integrated Circuits (ROIC) for HgCdTe Focal Plane Arrays of 1x4 and 72x4 photovoltaic detectors are represented. The analog circuit blocks are completely identical for both, while the digital control circuit is modified to
take into account the larger array size. The manufacturing technology is 0.35μm, double poly-Si, three-metal CMOS process. ROIC structure includes four elements TDI functioning with a super sampling rate of 3, bidirectional scanning, dead pixel de-selection, automatic gain adjustment in response to pixel deselection besides programmable four gain setting (up to 2.58pC storage), and programmable integration time. ROIC has four outputs with a dynamic range of 2.8V (from 1.2V to 4V) for an output load of 10pF capacitive in parallel with 1MΩ resistance, and operates at a clock frequency of 5 MHz. The input referred noise is less than 1037 μV with 460 fF integration capacitor, corresponding to 2978 electrons
Cointegration and Extreme Value Analyses of Bovespa and the Istanbul Stock Exchange
This paper investigates the long-term financial integration and bivariate extreme dependence between Bovespa and the Istanbul Stock Exchange. While a static cointegration test presents no evidence of long-term cointegration, the introduction of a structural break into the model shows that Bovespa and the ISE were cointegrated following the local crisis in Turkey in 2000. Dynamic cointegration tests and DCC-GARCH analysis also reveal that Bovespa and the ISE reacted strongly not only to systemic crises as expected, but also unexpectedly to local crises in each other. This shows that equity prices in two emerging markets in distant regions of the world can co-move in the absence of significant trade and financial linkages. This suggests that there are underlying processes that affect equity prices other than trade, financial linkages, macroeconomic ties, and FDI as the prior literature suggests. While episodic cointegration is found for Bovespa and the ISE, the extremes of these markets still possess asymptotic independence, suggesting diversification opportunities.cointegration, structural break, dynamic conditional correlations, bivariate extreme value, emerging markets, Turkey, Brazil
