BACKGROUND Racetrack surface is a risk factor for racehorse injuries and fatalities. Current research indicates that race surface mechanical properties may be influenced by material composition, moisture content, temperature, and maintenance. Race surface mechanical testing in a controlled laboratory setting would allow for objective evaluation of dynamic properties of surface and factors that ...
protein secretory systems are found in all living organisms including gram negative bacteria, and eukaryotic cell’s organelles that are derived from these bacteria. unlike all other living organisms, gram negative bacteria have different protein secretory systems. at least there are four different independent secretory systems, which are responsible to transport the secreted proteins to the mil...
Effect of air cushion layer right before impact of a rigid body onto water surface has been investigated in this paper. The study is mainly focused on evaluation of cushioning pressure and the resulting free surface elevation. The air flow is assumed to be an irrotational flow which is governed by Laplace equation. The air problem and the resulting response of the water free surface are suppose...
