An Analysis of the Economic Factors and Changes in Land-Use Associated with the Transition to a Beef Feedlot System in Waterloo County

The first objective of this study is to examine the transition from the traditional system of agriculture to a relatively new type of operation, the beef feedlot enterprise. This will incldue not only an examination of the actual transition but also the factors which were conducive to such a change. In this respect, the current, as well as the past position of beef in the agricultural economy, will be discussed as a contributing factor to the movement toward specialization. The views and attitudes of the framers in the study group concerning their change in vocation will also be examined and evaluated as an important indicator concerning the relative success of the beef feedlot venture. The second objective is to analyze the economics of the operations of a selected group of feedlot operations who are located in Waterloo County and who, recently, initiated the modification of their existing farm facilities to feedlot requirements. The economic situation of a system in transition is of major concern in determining the viability of the operation. The analysis will basically include a discussion and comparison of various resources common to a feedlot operation and the relative efficiency with which these resources are used by the study group memebrs. Here also, an indication will be given concernign the possible effect that the size of operation has on the use made of the resources contributing to the overall success of the operation. The third objective of the study is to provide for the reader some factual information on the beef feedlot system and to better acquaint the reader with this type of operation. This will involve a consideration of various methods of livestock production within the feedlot as well as an overview of some of teh characteristics and functions of a beef feedlot operation

A Solid breeder tokamak blanket designed for failure mode operation

Statement of responsibility on title-page reads: Franklin Chen, Peter Griffith, Thomas McManamy, and Gary Was"May 1977.""This study is basically an integration and extension of a doctor's thesis by Franklin Chen and a master's thesis by Gary Was."Includes bibliographical references (leaves 244-248)The objective of this study was to evaluate a new concept for a Tokamak type fusion reactor blanket. The design was based on using a packed bed of lithium aluminate as the breeding material with helium gas cooling. The unique aspect of the design was the assumption that small coolant leaks were inevitable and should not necessitate major maintenance. A modularized design was chosen with cylindrical breeder rods and graphite shim rods. Redundancy was provided by designing the blanket such that if a module failed it could be depressurized and its heat load shared by the neighboring operating modules. The thermal hydraulic analysis evolved analytical and computational methods for determining the temperature profiles of all components and the pumping power requirements. A computer program TRIPORT was developed to evaluate the tritium retention and transport. A one dimensional ANISN code was used to determine the breeding ratio for different configurations.!  The thermal hydraulic, neutronic and mechanical aspects of the Breeder Rod Shim Rod (BRSR) design were combined to determine a design window, that is the allowable range of system parameters. Unfortunately adequate breeding could not be demonstrated so that there was no open window. Basically the low breeding was caused by -he inherently poor breeding potential of LiAlO, combined with the additional structure required for failure mode operation. However, this conclusion is based on a specific design concept (BRSR) and further research in the area may prove more fruitful

Evaluation of the achievement of WSMPA conservation features and their target values for WSMPA Phase 1

At CCAMLR-38, the Delegation of the European Union and its Member States and Norway proposed that the Weddell Sea Marine Protected Area (WSMPA) should be adopted by CCAMLR in two phases: WSMPA Phase 1 and WSMPA Phase 2. A proposal to establish WSMPA Phase 1 has been submitted to CCAMLR-38. At this point, we provide brief information on the achievement of the WSMPA conservation features and their conservation targets for WSMPA Phase 1

Where the wild things are: Seasonal variation in caribou distribution in relation to climate change

In this study, we develop a method to analyse the relationships between seasonal caribou distribution and climate, to estimate how climatic conditions affect interactions between humans and caribou, and ultimately to predict patterns of distribution relative to climate change. Satellite locations for the Porcupine (Rangifer tarandus granti) and Bathurst (R. t. groenlandicus) caribou herds were analysed for eight ecologically-defined seasons. For each season, two levels of a key environmental factor influencing caribou distribution were identified, as well as the best climate data available to indicate the factor's annual state. Satellite locations were grouped according to the relevant combination of season and environmental factor. Caribou distributions were compared for opposing environmental factors; this comparison was undertaken relative to hunting access for the Porcupine Herd and relative to exposure to mining activity for the Bathurst Herd. Expected climate trends suggest an overall increase in access to Porcupine caribou for Aklavik (NWT) hunters during the winter and rut seasons, for Venetie (Alaska) hunters during midsummer and fall migration and for Arctic Village (Alaska) during midsummer. Arctic Village may experience reduced availability with early snowfalls in the fall, but we expect there to be little directional shift in the spring migration patterns. For the Bathurst Herd, we expect that fewer caribou would be exposed to the mines during the winter, while more caribou would be exposed to the combined Ekati and Diavik mining zone in the early summer and to the Lupin-Jericho mining zone during the fall migration. If changes in climate cause an increased presence of caribou in the mining sites, monitoring and mitigation measures may need to be intensified

Clinical trial of FK 506 immunosuppression in adult cardiac transplantation

The new immunosuppressive agent FK 506 was used as primary immunotherapy in conjunction with low-dose steroids and azathioprine in 72 patients subsequent to orthotopic cardiac transplantation. Overall patient survival at a mean follow-up of 360 days was 92%. The number of episodes of cardiac rejection (grade 3A or greater) within 90 days of transplantation was 0.95 per patient. The actuarial freedom from rejection at 90 days was 41%. Achievement of this level of immunosuppression is comparable with that of cyclosporine-based triple-drug therapy with OKT3 immunoprophylaxis. Thirty percent of patients were tapered off all steroids, and the average steroid dose in the group who received steroids was 8.6 mg of prednisone per day. The incidence of infection reflected the diminished necessity for steroids: seven major infections (10%) and 11 minor infections (16%). Renal dysfunction occurred during the perioperative period in most patients in this trial. However, the incidence of hypertension was 54% compared with 70% during the cyclosporine era. Ten adults underwent successful rescue therapy with FK 506 after cardiac rejection refractory to conventional immunotherapy. Side effects of FK 506 were notably few, and the results of the trial are encouraging for the future of the cardiac transplant recipient. © 1992

Rapid Fabrication of Flat Plate Cavity Phosphor Thermography Test Models for Shuttle Return-to-Flight Aero-Heating

Methods, materials and equipment are documented for fabricating flat plate test models at NASA Langley Research Center for Shuttle return-to-flight aeroheating experiments simulating open and closed cavity interactions in Langley s hypersonic 20-Inch Mach 6 air wind tunnel. Approximately 96 silica ceramic flat plate cavity phosphor thermography test models have been fabricated using these methods. On one model, an additional slot is machined through the back of the plate and into the cavity and vented into an evacuated plenum chamber to simulate a further opening in the cavity. After sintering ceramic to 2150 F, and mounting support hardware, a ceramic-based two-color thermographic phosphor coating is applied for global temperature and heat transfer measurements, with fiducial markings for image registration
