We describe recent observations and measurements realized with microstrip gas chambers (MSGCs) manufactured on boro-silicate glass coated with a thin layer of diamond-like carbon (DLC) having a surface resistivity around 4.1016Ω/❒. The role of the back-plane electrode configuration and potential in the detector performance has been studied. Even for this very high resistivity of the coatings, M...
Objective(s)Bioelectrical impedance is the measure of impedance of the body. Impedance consists of electric resistance and reactance. Phase angle (PA) is the tan value of the ratio of reactance versus electric resistance. PA depends on cell membrane integrity and on body cell mass. There exists a correlation between PA values and body cell mass.The objective of this study was to compare the PA ...
Polycrystalline samples of NdBa2-xLaxCu3O7-δ with x=0, 0.05, 0.10, 0.15, 0.20, and 0.30 were made by standard solid state methods. The transport and superconducting properties have been studied by the resistivity measurements as a function of temperature and doping concentration. In order to measurements the hole concentration in CuO2 planes, the room temperature thermoelectric power was measu...
In this study the Taguchi method, has been applied to optimize the heat treatment parameters for the corrosion resistance of AA6061 aluminum alloy. The experimental design consisted of four parameters (aging temperature, aging time, quenching environment and NaCl concentration), each containing three levels. Tafel polarization measurements were carried out to determine the corrosion resistance ...
A novel class of luminescent cyclometalated gold(III) alkynyl complexes has been demonstrated to possess EL properties and has been employed in the roles of electrophosphorescent emitters or dopants of organic light-emitting diodes (OLEDs) with high brightness and efficiency.
