Original scientific paper In the pipelines of water supply systems, the water hammer phenomenon often arises during rapid unsteady developments. Pipelines are mostly protected using an air vessel, which is designed by means of equations for oscillations of water mass. In this study, an analysis is made of the impact of pressure increases caused by water hammer on pressure variations in pipeline...

Background and Objectives: Application of local vacuum pressure to human skin during laser irradiation results in less absorption in the epidermis and more light delivered to targeted vessels with an increased blood volume. The objective of the present numerical study is to assess the effect of applying local vacuum pressure on the temperatures of the epidermis and small vessels during port win...

Thick-walled high-pressure vessels are a fairly common type of technical device as part technological equipment operated at various hazardous production facilities. Reliability indicators pressure and their change during operation largely determine the failure-free whole, potential failures subject to consideration when conducting risk analysis operating equipment. The article discusses probabi...

At the request of the U.S. Army Project Manager for Non-Stockpile Chemical Materiel, Sandia National Laboratories is developing a transportable system for destroying recovered, explosively configured, chemical warfare munitions. The system uses shaped charges to access the chemical agent and burster followed by chemical neutralization to destroy them. The entire process takes place inside a sea...
