mechanical damage due to harvesting, handling, and other processes is an important factor that affects the seeds quality. seed damage results in lower grain value and more storability problem and reduces seed germination and seedling vigor and subsequent yield of crops. tests were conducted to determine the percentage of physical damage (ppd) and percentage of loss in germination (plg) of wheat...
Background and aims: Health care sector has job-related health problems and hazards. Patient handling is a main risk factor of musculoskeletal disorders among Health Care Workers (HCW). The present study aimed to ergonomic evaluation of client transfer between bed and stretcher through common way and using mechanical patient transfer aid device. Methods: In this study, parameters of comfort,...
Micro-electro-mechanical systems (MEMs) are Combination of electrical and mechanical components in Micron dimensions. In recent years, holding, actuating methods and handling of MEMs components such as microgripper, microsensors and etc. have been deeply studied. Microgrippers for handling, positioning and assembling of micro components are very useful so that for clamping need actuation create...
in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
Nursing aides are particularly susceptible to manual handling injuries because they have the primary responsibility for heavy lifting. The aim of this study was to determine why a specific group of nursing aides have the highest manual handling injury rate in their hospital. The study investigated the adequacy of the manual handling training program, knowledge of manual handling, mechanical aid...
