    For the past three decades, obesity has been cited as a growing epidemic in the United States, according to the New England Journal of Medicine (NEJM). Obesity is a major contributing problem to a number of medical conditions. Studies in the NEJM have “correlated obesity with myriad cancers, coronary heart disease, hypertension, diabetes, and stroke,” and other health-related problems (Fumento). Healthcare experts, doctors, and practitioners estimate it will cost billions of dollars a year to bring this problem under control and it is a major contributing factor in the rising cost of healthcare (Oliver 1). Luppold, Violette, and other practitioners argue that “Rising health care costs affects the economic vitality . . . from government, business, and non-profit agencies to families and individuals” (1). If a child is overweight by the age of six, the likelihood of that child becoming obese in adulthood rises to 50 percent, according to Dietz (411S) and will struggle with obesity over a lifespan (Karp 1). Obesity is a “disorder of energy imbalance; that is, more energy is consumed” (Luppold and Violette 1). One of the major groups afflicted by this epidemic is a college student and this problem usually starts in the home. Most college students are obese and super-sized fast food deals are fattening for the consumers. The purpose of this project is to discuss the theoretical implications of obesity: defining it, its causes and cures, and to create a nutrition guide to help college students maintain a healthy lifestyle. Many people would argue that obesity is a choice because over-eating or eating the wrong foods is a choice. There are others who would argue that people become slaves to food and that the choice of controlling one’s over-eating habits is diminished. What exactly is obesity and how is it determined? Obesity is determined when an individual’s body weight is compared to his or her height, which is called the Body Mass Index, better known as BMI. When the weight is approximately 20 percent higher than the ideal weight, given the persons’ height, then that person is considered obese. If college is an option for an individual who is raised in an unhealthy eating environment it can be a catalyst for changing bad eating habits to help prevent and cure many problems that lead to bad health. Genetic, psychological, cultural, social, and economic factors are contributing to factors to obesity but bad eating habits are a major factor. For this reason, I provide a general overview of obesity and some health-related problems associated with it such as obesity and Diabetes (Type I & Type II Diabetes); obesity, hypertension, and coronary heart disease; obesity and cholesterol, and some tips for changes in controlling obesity

    This Note seeks to place Nixon in the context of Missouri law in order to analyze the court\u27s holding and its attendant consequences. First, this Note will review Missouri\u27s venue law leading up to Nixon. Next, this Note will examine the court\u27s reasoning, consider its interpretation of the newlyenacted venue provision of section 508.012, and explore the issues and implications arising from the decision. Finally, this Note will conclude that in order to mitigate Nixon\u27s departure from the legislative goals of the Tort Reform Act, future courts will limit the decision\u27s reach by failing to apply its reasoning beyond the narrow procedural issue presented in Nixon

    Fuel composition influences fire characteristics and understorey hardwoods in pine savanna

    Get PDF
    Fuels in the groundcover of frequently burned south-eastern pine savannas include shed leaves of trees. Flammable needles of longleaf pine (Pinus palustris) potentially increase maximum fire temperatures and durations of heating, negatively affecting other trees within the groundcover. Less flammable leaves that accumulate around the bases of understorey stems of hardwood trees such as mockernut hickories (Carya alba) in the fall potentially depress maximum fire temperatures and durations of heating, enhancing post-fire recovery. We experimentally manipulated amounts of pine and hickory leaves beneath understorey hickory stems in a pine savanna, measured temperatures during prescribed fires and assessed combustion of fuels and survival and regrowth of hickory stems. Pine needles increased fire temperatures and durations of heating relative to herbaceous fuels and increased combustion of hickory leaves. Hickory leaves, however, neither increased nor decreased fire characteristics relative to herbaceous fuels. All hickories survived fire by resprouting. When pine needles were absent, most hickories resprouted from buds located above-ground along the stem at heights inversely related to temperature increase. In contrast, resprouting occurred only from underground root crowns when pine needles were present. Such differences in locations of resprouts influenced sizes of stems at the end of the growing season. Synthesis. Groundcover fuels containing flammable leaves shed by pyrogenic species of savanna trees affect local fire characteristics and resprouting of non-pyrogenic understorey trees. Thus, local variation in flammable fuels produced by pyrogenic species can engineer landscape dynamics of other trees in savannas. © 2012 The Authors.

    Manned Aircraft Versus Small Unmanned Aerial System—Forestry Remote Sensing Comparison Utilizing Lidar and Structure-From-Motion for Forest Carbon Modeling and Disturbance Detection

    Get PDF
    Sustainable forest management relies on the acquisition of timely (change detection) and accurate structural information of forest landscapes. Light detection and ranging (lidar) remote sensing platforms enable rapid, three-dimensional (3-D), structural data collection with a high spatial resolution. This study explores a functional carbon model applied to a dense, closed deciduous forest. Data are collected by manned airborne systems and unmanned aerial system, producing both lidar and structure-from-motion (SfM) 3-D mapping. A hybrid approach combining cost-effective SfM-generated data with lidar-derived digital elevation models also is explored, since the SfM fails to produce adequate terrain returns. Carbon modeling results are comparable to those achieved by the initial developers (r2 ¼ 0.64 versus r2 ¼ 0.72), despite the challenging uneven-aged forest environment. Vertical profiles, mapped utilizing a volumetric point density from the manned airborne lidar, are leveraged to train a binary classifier for disturbance detection. Producer’s accuracy, user’s accuracy, and Kappa statistic for disturbance detection are 94.1%, 92.2%, and 89.8%, respectively, showing a high likelihood of detecting disturbances (harvesting). The results bode well for the use of unmanned aerial system (UAS) systems, and either lidar or SfM, to assess forest stocking. Although disturbance detection is successful, further study is required to validate the use of UAS, and especially SfM, for this task

    Measurements of quantum yields of bromine atoms in the photolysis of bromoform from 266 to 324 nm

    Get PDF
    The quantum yield for the formation of bromine atoms in the photolysis of bromoform, CHBr_3, has been measured between 266 and 324 nm. For 303 to 306 nm the quantum yields are unity within the experimental uncertainty of the measurements. At longer wavelengths, where the bromoform cross sections decrease rapidly, an apparent trend to slightly lower quantum yields is probably the result of systematic and random errors or incorrect CHBr_3 absorption cross sections. Support for a unit quantum yield for all wavelengths longer than 300 nm comes from the recent theoretical calculations of Peterson and Francisco. At 266 nm the bromine atom quantum yield is 0.76 (±0.03), indicating that at least one additional dissociation channel becomes important at shorter wavelengths. For modeling of the troposphere, it is recommended that a quantum yield of unity be used for wavelengths of 300 nm and longer

    Circulation is the process of loaning and returning of library materials. This study intends to determine the circulation trends of newly acquired print materials in the a university library in Northern Philippines Libraries. The data gathered from the Follett Destiny Library System of the University Libraries to determine the circulation trends of materials which purchased on the year 2014-2017. The total number of purchased title is 3002.Based on the result, the materials from General Interest/ Fiction/Graphic novels has the highest books circulated. It also showed that the USL Libraries purchased expensive books but not frequently used by the users and despite the high number of acquisitions directly relevant to the courses of Engineering, Architecture, Technology Education, Accountancy, Business, Hospitality and Education, Arts, Health, books on Graphics were more frequently borrowed 577 books, by both employees and students. It shows that even if the acquisition librarian did not purchase in the year 2016, still the general Interest/ Fiction/ GN/ Graphics has the highest books circulated. The total number of book title borrowed is lower than those of not used. The university library is purchasing the title of books that are being requested by the library patrons but most of the materials were not being utilized. The library users prefer spending their time in reading leisure books. The utilization of printed academic books in the university library is slowly decreasing

    Pyrogenic fuels produced by savanna trees can engineer humid savannas

    Natural fires ignited by lightning strikes following droughts frequently are posited as the ecological mechanism maintaining discontinuous tree cover and grass-dominated ground layers in savannas. Such fires, however, may not reliably maintain humid savannas. We propose that savanna trees producing pyrogenic shed leaves might engineer fire characteristics, affecting ground-layer plants in ways that maintain humid savannas. We explored our hypothesis in a high-rainfall, frequently burned pine savanna in which the dominant tree, longleaf pine (Pinus palustris), produces resinous needles that become highly flammable when shed and dried. We postulated that pyrogenic needles should have much greater influence on fire characteristics at ground level, and hence post-fire responses of dominant shrubs and grasses, than other abundant fine fuels (shed oak leaves and grass culms). We further reasoned that these effects should increase with amounts of needles. We managed site conditions that affect fuels (time since fire, dominant vegetation), manipulated amounts of needles in ground-layer plots, prescribed burned the plots, and measured fire characteristics at ground level. We also measured characteristics of ground-layer oaks and grasses before, then 2 and 8 months after fires. We tested our hypotheses regarding effects of pyrogenic pine fuels on fire characteristics and vegetation regrowth and explored direct and indirect effects of fuels on fire characteristics and vegetation using a structural equation model. Pine needles influenced fire characteristics, elevating maximum temperature increases, durations of heating above 60°C, and fine fuel consumption considerably above measurements when fuels only included other savanna plants. Presence of pine needles depressed post-fire numbers of oak stems and grass culms, especially in the interior of grass genets, as well as post-fire flowering of grasses. The structural equation model indicated strong direct and indirect pathways from pine needles to post-fire responses of oaks and grasses. The experimental field tests of hypotheses, bolstered by structural equation modeling, indicate pyrogenic fine fuels modify characteristics of prescribed fires at ground level, negatively affecting dominant ground-layer oaks and grasses. Frequent fires fueled by pyrogenic needles should maintain humid savannas and generate spatial pyrodiversity that affects composition and dynamics of pine savanna ground-layer vegetation
