Proposed Design Modifications To Reduce Risk Of Operating Rotary Field Mowers, Katie L. White, Larry G. Wells, Scott A. Shearer, Larry R. Piercy
Proposed Design Modifications To Reduce Risk Of Operating Rotary Field Mowers, Katie L. White, Larry G. Wells, Scott A. Shearer, Larry R. Piercy

The primary objective of this project was to reduce risk of injury associated with operating a rotary mower driven by a tractor power take-off (PTO) by developing and evaluating design improvements and determining their economic feasibility. Researchers have concluded that alteration of machinery design has a greater impact on the reduction of accidents than safety training. Implementation of an Operator Presence Sensing System (OPSS) and removal of the PTO are the two injury-reducing, engineering modifications evaluated by this research. Hydraulic power allows this to occur by providing dynamic braking, few moving parts (removal of the PTO), and controllable power. A …
Reconditioning Corn And Soybeans To Optimal Processing Moisture Contents, Michael D. Montross, Dirk E. Maier
Reconditioning Corn And Soybeans To Optimal Processing Moisture Contents, Michael D. Montross, Dirk E. Maier
Biosystems and Agricultural Engineering Faculty Publications
Experimental trials were carried out to evaluate the technical feasibility of reconditioning overly dry corn and soybeans to optimal market and processing moisture contents. Data obtained from experimental trials were used to validate an aeration simulation model. This model was used to evaluate the feasibility of reconditioning soybeans and corn. Reconditioning of grain was feasible at low airflow rates (0.11 m3 min–1 t–1) over a six-month period when an automatic aeration controller was used. Using downflow aeration and monthly unloading of the bin allowed for the greatest net economic gain. Predicted reconditioning in Des Moines, Iowa, …

Avhrr Estimates Of Surface Temperature During The Southern Great Plains 1997 Experiment, Amy L. Kaleita, Praveen Kumar

In this study we aim to (1) explore the differences in the accuracy of satellitederived land-surface skin temperature for day and nighttime observations, (2) assess the effects of large solar zenith angles, and (3) develop an understanding of the spatial variability of the observed temperatures. Land-surface skin temperatures are obtained using the split-window technique from observations of the AVHRR instrument aboard the NOAA-12 and NOAA-14 satellites for the SGP97 (Southern Great Plains 1997) hydrology experiment. From the study of several days of observations we find that observed biases with respect to the ground temperature, both during day and night, are …

These guidelines apply to the management of Western Australia piggeries in Western Australia, including intensive Growing pigs under intensive conditions where the and extensive operations, straw-based housing and animals spend their entire life cycle indoors, is an combinations of these (otherwise referred to as semi- important part of the Western Australian and intensive housing).
Simulated Performance Of Conventional High-Temperature Drying, Dryeration, And Combination Drying Of Shelled Corn With Automatic Conditioning, Michael D. Montross, Dirk E. Maier
Simulated Performance Of Conventional High-Temperature Drying, Dryeration, And Combination Drying Of Shelled Corn With Automatic Conditioning, Michael D. Montross, Dirk E. Maier
Biosystems and Agricultural Engineering Faculty Publications
Combination drying, based on computer simulation, was evaluated as an alternative drying technique to traditional high-temperature drying and dryeration. Simulation models of high-temperature crossflow drying and in-bin drying and conditioning were used to evaluate the performance of conventional crossflow drying and full-heat crossflow drying followed by dryeration or natural-air drying for Indianapolis, Indiana, and Des Moines, Iowa. Energy costs from propane, electricity, moisture shrink below the market moisture content, and dry matter loss were estimated to find the total average drying cost over 29 years. Dryeration and combination drying reduced the total drying cost by approximately 10% compared to conventional …
