Foldable rollover protective structures: Universal lift-assist design.

Biosyst Eng 2019 09 16;185:116-125. Epub 2019 Mar 16.

Department of Biosystems Engineering and Soil Science, University of Tennessee, Knoxville, TN, USA.

The numbers of agricultural tractor rollover fatalities occurring with foldable rollover protective structures (FROPS) in their lowered position are significant. Raising and lowering the FROPS is a time consuming and strenuous process, and operators often leave the FROPS in the folded-down position providing no protection during a rollover. The purpose of this project is to design, manufacture, and test a lift-assist mechanism to raise and lower the FROPS from the operator's seat. Read More

Low frequency aeration of pig slurry affects slurry characteristics and emissions of greenhouse gases and ammonia.

Biosyst Eng 2017 Jul;159:121-132

Rothamsted Research, North Wyke, Okehampton, Devon EX20 2SB, UK.

Low frequency aeration of slurries may reduce ammonia (NH) and methane (CH) emissions without increasing nitrous oxide (NO) emissions. The aim of this study was to quantify this potential reduction and to establish the underlying mechanisms. A batch experiment was designed with 6 tanks with 1 m of pig slurry each. Read More

Web-based forecasting system for the airborne spread of livestock infectious disease using computational fluid dynamics.

Biosyst Eng 2015 Jan 12;129:169-184. Epub 2014 Nov 12.

EPINET Co., Ltd., 1012, Geumgang Penterium IT Tower, 282, Hagui-ro, Gwanyang-dong, Dongan-gu, Anyang-si, Gyeonggi-do, 431-810, Korea.

Livestock infectious diseases, such as foot-and-mouth disease (FMD), cause substantial economic damage to livestock farms and their related industries. Among various causes of disease spread, airborne dispersion has previously been considered to be an important factor that could not be controlled by preventive measures to stop the spread of disease that focus on direct and indirect contact. Forecasting and predicting airborne virus spread are important to make time for developing strategies and to minimise the damage of the disease. Read More
