Resource planning for a rare metals corporation using mixed integer goal programming and resource planning and management system

Creator:: Barneson, John
Abstract:: A system's analysis study utilizing Resource Planning and Management System network methodology, integer programming, and goal programming is presented. The integrated approach is developed and applied to the rare metals production process of the Oregon Metallurgical Corporation (OREMET). As defined by OREMET management, optimization of the production process required the...

Effect of two methylcarbamates on the toxiciity of isopropyl m-chlorocarbanilate (chlorpropham) to safflower (Carthamus tinctorius L.) and common buckwheat (Fagopyrum esculentum Moench.)

Creator:: Kirkland, Kenneth
Abstract:: Addition of the methylcarbamate compounds p-chlorophenyl N-methylcarbamate (PPG-124) and 1-naphthyl N-methylcarbamate (carbaryl) to various herbicides has resulted in reduced rates of degradation. Carbaryl affects the degradation of certain herbicides in both plants and soils while PPG-124 has only been demonstrated to affect degradation in soils. Both these materials are effective...

Computerized safety analysis technique for secondary highways

Creator:: Nichols, Kevin Scott
Abstract:: Evaluation of the safety hazards along a highway is usually performed at specific locations and on known hazards. But, it is also important to find any unrecognized hazards and their locations. Many factors contribute to accident potential, and the combined effect of several of them could produce a hazard that...

Methods of extraction and characterization of polyphenol oxidase from d'Anjou pears (Pyrus Communis L.)

Creator:: Smith, Denise Myrtle
Abstract:: Using phenolic scavengers different methods were examined to determine the optimum conditions for extracting polyphenol oxidase (PPO) from d'Anjou pears. Efficiency of the extraction was evaluated based on browning of the extract, PPO activity per g of pear tissue, absorption scan of 410 nm to -240 nm, and the isozyme...

Direct digital speed control system for a DC motor using a minicomputer

Creator:: Evans, Donald LeRoy
Abstract:: Direct digital control is becoming quite common in the control of industrial processes. However, due to the relatively high accuracy of both analog and conventional digital systems for controlling the speed of a dc motor, there has been a reluctance to try DDC for this purpose. This thesis describes a...

Resistance in snap beans, Phaseolus vulgaris L., to adult western spotted cucumber beetle, Diabrotica u. indecimpunctata Mann

Creator:: Eltoum, Elameen M. A.
Abstract:: Studies to evaluate resistance in snap beans, Phaseolus vulgaris L. to adult western spotted cucumber beetles, Diabrotica u. undecimpunctata Mann. were conducted in greenhouse cages, field cages, field plots, and in temperature controlled cabinet in the laboratory. Results showed that there were differences in susceptibility to adult feeding injury between...

Nutrient cycling under 450-year-old Douglas-fir stands

Creator:: Abee, Albert
Abstract:: To investigate the movement of elements (N, P, k, Ca, and Mg) from the tree crowns by natural litterfall and leave wash, plots were established on six 450 year-old growth stands at the H. J. Andrews Experimental Forest. The following are the results of the data analyses. Elemental concentrations contained...

An executive for simulation of process dynamics and control

Creator:: Olgun, Ferdi Tahir
Abstract:: A simple package of routines that can be easily implemented in small minicomputers used in process control, was developed to simulate dynamic systems and computer control of simple dynamic systems found in the process industries. Two different systems, a gas absorber and a fifth-order transfer function were chosen as processes...

A software package for an intelligent graphic display terminal

Creator:: Nelson, Cecil L.
Abstract:: A cost reduction analysis is performed by coordinating the exchange of LANDSAT (formerly ERTS) data between a CDC 3300 and a PDP8/L minicomputer. The LANDSAT data is displayed on a 4002 Tektronix terminal by means of a grayscale output. Large amounts of data and number manipulation are processed in the...
