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

Biosystems and Agricultural Engineering Faculty Publications

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 …

The Effect Of Heat On Fingertip Sensitivity Of Meat Processing Workers, Brian James Finder

Dissertations and Theses @ UNI

Current research indicates that acute non-freezing cold exposure elicits short-term performance problems; namely reduced upper extremity temperature, blood flow, tactile sensitivity, and dexterity. However, various animal-related studies indicate that humans are at increased risk of incurring semi-permanent upper extremity nervous system dysfunction as a result of repeated cold exposure.

The purpose of this research was to examine various factors that may contribute to hand/arm nervous system impairment of individuals who work in a refrigerated meat-processing environment. The methodology used was primarily the Experimental Method and from studies conducted by other researchers, was driven by the following questions:

(1) How would …
