The paper presents relation for maximal pressure-volume work for closed systems by using principles of I and II law of thermodynamics, used in reversible processes in which mechanical and thermal balance has been achieved. For full interpretation of this problem for two characteristic cases, graphical review in p-v diagram is given, where in an obv...

While a liquid is dripping out of a capillary tube, there is a possibility to affect the characteristics of the exiting flow in certain ways. One of the ways already used is by introducing an electric field that can be used to change the average droplet diameter and the droplet size distribution. This process is called electrospraying, while the th...

The methods of analysis in forensic must be reliable in order for the results of the analysis to be accepted as evidence in court proceedings. The reliability of methods is checked through the validation process, which should be performed before introducing a method into the routine practice of the laboratory. This paper describes the procedure for...
