Blood transfusion centers are under considerable pressure to produce platelet concentrates with high quality and safety due to the short shelf life of 3-5 days as well as possible bacterial and viral contaminations. For a variety of reasons, many Europeans have changed their methods of component production from whole blood using the North American standard platelet-rich plasma method to the buf...

The researches included Polish Landrace (PL) breed pigs and Polish Large White (PLW) x PL and PLW x Duroc crossbreds. During the fattening season, blood was collected for biochemical analyses four times. Blood plasma was examined to determine the content of total protein, albumin, creatinine, urea, uric acid, total bilirubin, cholesterol, triglycerides and glucose as well as a level of indicato...

The dust residual charge distribution in the late afterglow of a dusty plasma has been measured for different operating pressures. It has been shown that the dust charge distribution can be approximated by gaussian function with mean value close to −3e, rms about 1e and a tail in the positive charge region. Numerical simulations of the evolution of the dust charge distribution showed that the s...

We develop a covariance-matrix-based uncertainty analysis for vector-network-analyzer scattering-parameter measurements. The covariance matrix captures all of the measurement uncertainties and statistical correlations between them. This allows the uncertainties of vector-network-analyzer scattering-parameter measurements to be propagated into the uncertainties of other quantities derived from s...

Aqua treadmill is mainly used for rehabilitation purposes, but research indicates that this equipment could be used for training as well. Th e few studies performed with aqua treadmill mainly followed lactate and heart rate changes. Th erefore, the aim of this study was to test the eff ect of high water treadmill training on several blood parameters and on the correlations between them. Eight s...

A novel design of ICP with high coupling efficiency is presented. The efficiency augmentation is achieved using a thin window and an antenna coil enhanced by a ferromagnetic core. Considerable improvement of ICP electrical and plasma characteristics is demonstrated through experiments in ICP operated at 2 MHz in a wide range of argon gas pressures between 1 mTorr and 1 Torr, and discharge power...
