The David and Frances Scott Memorial Concert

This is the program for the David and Frances Scott Memorial Concert, presented by Sigma Alpha Iota, on February 21, 1989. Guest vocalists Denise Edds, soprano, and Stephen Edds, baritone, were accompanied by Robert Lindley on piano

Headwater Streams of the Flint Hills

Among the most beautiful environments of the Flint Hills are the springs and headwater streams that are part of and help to carve the landscape. Meandering through the vast sea of grass, hundreds of free-flowing ribbons of water might go unnoticed as we speed along the highway

Small Animal Nutrition

In general, the body needs daily intakes of a proper proportion of carbohydrate and fat for energy, amino acids for the synthesis of tissue proteins, and vitamins for special structures. In addition, it requires inorganic ions and water for the ionic environment, and inorganic ,elements such as iron, cobalt, manganese and copper, for organic combination. Thus, if dietary therapy emphasizes only one or two, or anything less than the whole group of ingredients needed daily, then the clinician is depending upon the body reserves to correct the deficiency. Similarly, a study of any particular ingredient such as the protein component must be done with a diet which supplies, to the best of our knowledge, all other essential ingredients

Optimizing Output Power of a Variable Speed Synchronous Generator by Controlling Excitation and Load Restistance

Since 1973 the University of Massachusetts Energy Alternatives Program has been involved in a project, the UMASS Wind Furnace (WF-1) which is directed at supplying the heating needs of households in northern climates. This project had as its inception an attempt to design and build fiberglass rotor blades. Since then the combined efforts of students and faculty from many engineering departments have produced a facility whose purpose is the study of wind and solar energy for useful purposes. The current Wind Furnace Model (WF-1) utilized a wind-driven electromechanical system to generate electrical energy. This energy is then dissipated through resistance heaters and either stored thermally or delivered directly to the house. It is the theory and design of the electrical power system that is the primary topic of this report. In 1974 during the design stage o f the Wind Furnace, I volunteered to work on the electrical power system for this wind turbine generator (KTG). Basically this involved describing how the generator was to be used to provide heat to the house and how it would interface with the rest of the KTG. As a beginning I was given a plot of output power as a function of wind speed representing the desired WTG performance. This preliminary curve, Figure 1, was based on the best estimates available a t that time o f the performance o f the blades and mechanical transmission coupled to a crude model of the generator, based on the manufacturer\u27s data sheets (see Appendix A). The curve in Figure 1 shows the output power as a cubic function at wind speed, with rated conditions o f 25.32 Kw at 26.1 mph. The final cubic curve, Figure 2, has as rated conditions an output of 25 Kw a t 26.1 mph, and 1800 rpm at the generator. The low end of the generator\u27s speed range, 400 rpm, was set by the cut-in wind velocity of approximately 6 mph. It was my opinion then that a better generator model was needed in order to arrive at a method of controlling the generator for the desired output. That concern has led to this thesis

Long-Term Study of Benthic Communities on the Continental Shelf Off Cameron, Louisiana: A Review of Brine Effects and Hypoxia

A long-term data set compiled from our studies and a variety of investigations was analyzed to determine the effects of nine years of discharged brine (concentrated salt water) on benthic organisms surrounding a brine diffuser off Cameron, Louisiana (USA). These investigations began three months before brine discharge was initiated in 1981. A preliminary summary by Giammona and Darnell (1990) relied on just three years of discharge data and gave misleading reports of brine impacts. Brine effects over the nine years of study were minimal, in part because the fine sediments of the study area were numerically dominated by opportunistic species. mostly estuarine taxa, that showed dramatic population fluctuations both spatially and temporally. These fluctuations in benthic densities were the most salient characteristic of the study area. They resulted from summer hypoxia and anoxia in bottom waters, not from brine. The hypoxia was related to Mississippi River discharge and subsequent salinity stratification. Hypoxia eliminated some taxa and severely reduced populations of most benthic species. The only significant differences between communities near the diffuser and those outside the influence of its discharged brine resulted from water-column mixing by the discharged brine, which oxygenated waters around the diffuser and stabilized the salinity of bottom water at the stations near the diffuser. This enhanced benthic diversity around the diffuser and resulted in greater populations during some seasons

Design And Evaluation Of The Umass WF-1 Kilowatt Hour Meter

A kilowatt-hour meter was designed, built and evaluated for use with the UMass Wind Furnace. A meter, capable of measuring the variable frequency variable voltage output of the wind turbine, was needed. This report describes this somewhat unique instrument, including its design and calibration
