    AbstractLet {Fr}0⩽r⩽p be a family of Banach spaces satisfying, if 0⩽r1⩽r2⩽p, (i)Fr1 ⊇ Fr2; (ii)¦f¦r1 ⩽ ¦f¦r2 (f ϵ Fr1); and (iii)ϑ(r) = ln(¦f¦r) is a convex function. Let G0 be a Banach space and. F be a Gâteaux differentiate mapping, and suppose that F′(x)(Fp) is dense in G0. Under appropriate assumptions, the equation F(x)=0 has a solution in Fr for 0⩽r⩽p. The results extend the Inverse Function Theorem of J. Moser to the class of Gâteaux differentiable operators

    Solution of the two-dimensional multigroup neutron diffusion equation by a synthesis method

    Get PDF
    A method, called the higher mode synthesis method, for the solution of the two-dimensional neutron diffusion equation is developed. In this method, the two-dimensional eigenfunction is expanded in terms of one-dimensional fundamental and higher eigenfunctions. A substitute, weight, and integration procedure is applied and the two-dimensional equation is reduced to a one-dimensional equation in terms of expansion coefficients. The expansion coefficients are combined with the trial functions in order to obtain the two-dimensional eigenfunction. This procedure results in a significant reduction of computation time as compared with standard iteration methods --Abstract, page ii

    The Effects of SMS Implementation on Safety Culture Within Helicopter Emergency Medical Services

    Safety Management Systems (SMS) have now become regulation within FAR Part 121 operations with U.S. airports and FAR Part 135 operators coming next. An assessment of the implementation of voluntary SMS programs and their effects on safety culture within major U.S. Helicopter Air Ambulance (HAA) operators was conducted. This study is designed to see if safety management systems, safety culture or the lack thereof changes the perception of HAA operators and crew members. A Likert style survey was administered to HAA pilots, paramedics, and flight nurses who were asked for their perception on their ability to communicate freely, belief their organization’s culture was a Just Culture, and the effectiveness of certain hazard mitigation protocols popular to the industry. The survey data revealed that SMS has been fairly well received by the working roles in these HAA operations. It also showed that some difference in opinion surfaced between the most experienced group (twenty plus years) and less experienced respondents (\u3c twenty years)

    Electrical Safety in the Hospital

    Electrical safety has become n important part of hospital management. The potential danger to patients and staff has increased, as health care becomes more sophisticated. Due to the unique situation that exists in hospitals, most hospital personnel do not understand the problems that occur. The problem is greater in smaller hospitals that do not have the time, money or qualified personnel to deal with the problem. Hospital electrical safety is not a complex problem. A basic safety program can be initiated if the personnel have a basic understanding of electricity and its effects on the body. Many nurses in the hospital lack training in electricity while many maintenance men do not understand physiology. To deal with this lack of knowledge, this thesis presents a home study text which presents useful information for an electrical safety program

    Farm-scale Production of Fuel Ethanol and Distillers\u27 Wet Grains from Corn and Corn-whey Mixtures

    Since the Arab oil embargo of 1973, we have become increasingly aware of the finite nature of our petroleum supplies. Current studies estimate that our supplies of petroleum will be depleted in the next 25 to 50 years. As supplies diminish and prices rise, we will need alternate forms of energy to take up the slack. One of the leading alternatives is the use of biomass in the production of liquid fuel that is, conversion of cellulose, starch, glucose, or other carbohydrates to ethanol. In the United States, the fuel ethanol industry is still in its infancy. Approximately a dozen large scale plants provide the bulk of the fuel ethanol currently used for octane enhancement and gasohol production. Numerous other large-scale plants are on the drawing board. These larger plants use ethanol production processes which have been extensively studied and characterized. On the other end of the spectrum are the smaller scale, farm or cooperative plants, which produce 0.7 to 4 million liters of ethanol per year. This size plant has only been in existence for 3 - 4 years and, consequently, there is a distinct lack of research information pertaining to them. While the overall process of ethanol production is similar for large and small scale plants, there exists many significant differences between the two scales. It is in these areas of difference where the process must be modernized and optimized before true technical and economical feasibility can be achieved for small scale plants. My research was based upon the small-scale-production of fuel ethanol from biomass. This size operation can be used by large farms, farm-based cooperatives, or community sized plants. The small plant size significantly reduces transportation costs, as the surrounding area supplies the raw materials and uses the products. thus, a community and the surrounding area could substantially reduce their dependence on foreign energy sources, provide a new and stable market for agricultural products, provide new jobs, and stimulate the local economy by adopting a locally based fuel alcohol production system. However, before this industry can be fully developed, the production of fuel ethanol must be modernized so that the process can be carried out more efficiently. It was the purpose of this study, then, to optimize the small-scale production of ethanol by incorporating new technologies into the basic process of fuel ethanol production from biomass. The primary emphasis of my research was to optimize the cooking, fermentation, and centrifugation processes involved in the production of fuel ethanol. This involved an initial study of existing plant procedures and operations for the purpose of collecting baseline data on plant performance. Utilizing this data, plant components, procedures, and feedstocks were then altered so that the process could be optimized in terms of time, temperature, energy, cost, yield, and other significant parameters
