Multivariate geostatistical analysis of groundwater contamination by pesticide and nitrate

Creator:: Smyth, Jeffrey D.
Abstract:: A field study was conducted to determine the applicability of multivariate geostatistical methods to the problem of estimating and simulating pesticide concentrations in groundwater from measured concentrations of nitrate and pesticide, when pesticide is undersampled. Prior to this study, no published attempt had been made to apply multivariate geostatistics to...

Assessing groundwater vulnerability to contamination using finite element modeling and geographic information systems

Creator:: Rea, Alan H.
Abstract:: A method was developed for assessing the vulnerability of groundwater to contamination from contaminant sources at the soil surface, using a numerical groundwater flow model linked to a digital map database. The method was applied using the pcARC/INFO Geographic Information System (GIS) to input, store, and manipulate base maps, resulting...

Microprocessor control and numerical model for broiler house summer ventilation utilizing a rockbed heat sink

Creator:: Chen, Chaur-Fong
Abstract:: Summer brooding often requires some form of air modification in addition to maximizing ventilation rate to prevent animal heat stress and possible death due to hyperthermia. A rockbed thermal storage module was designed and constructed to provide sensibly cooled air for a broiler space under summer brooding conditions. A mathematical...

Cooling and mass transfer rates in fresh fruits

Creator:: Chadwick, Jonathan Michael
Abstract:: Moisture loss from fresh fruits results in lost revenue to producers, storage/packing companies, distributors, and increased prices for the consumer. Improved methods of storage and handling are necessary to help prevent moisture loss and retard spoilage. A literature review was conducted to improve knowledge on past and current studies involving...

Computer simulation of transient refrigeration load in a cold storage for apples and pears

Creator:: Adre, Norberto
Abstract:: Increased consumer demand for fresh fruit throughout the year has created a need for long term storage. Long term storage of fruit uses more energy than fresh market products, thus increasing production cost. Pacific Northwest energy costs and more competition for markets has made energy conservation an important factor to...

A slatted floor portable shelter for lambing in winter rainfall pastures

Creator:: Nicholson, Martin Theodore
Abstract:: A survey of Oregon sheep producers conducted as part of this research, indicated that lambing losses by sheepgrowers in winter rainfall areas of Oregon currently average 16 percent. The majority of the lambs born in these areas are born in pastures without the benefit of shelter. The utilization of portable...
