mrs method is one of the new geophysical methods that directly detects the groundwater. by using this method, one can determines some parameters of aquifer (porosity, permeability and transmissivity). the purpose of this research is the application of mrs method in the conductive ground. combination of mrs and rs method is used for better detection of the aquifer in the region of abyek located ...

In their recent paper, Roberts et aL (1979) report the following values of intracellular (i), extracellular (o), longitudinal (<f), and transverse (t) resistivity for canine ventricular muscle: r^ = 450 ohms-cm, rot = 750 ohm-cm, ru = 360 ohm-cm, and rit = 3800 ohm-cm. The ratio W r ^ is 1.67. In an earlier paper, Clerc (1976) reported the following resistivity ratios for trabecular bundles fro...

The pedicle screw diameter, composite and design are variables that can affect the threshold of intraoperative electromyographic monitoring. Even though we know that larger diameter objects tend to have less resistance, no study documented the effect that this variable could have on pedicle screw resistance. Using high quality equipment, resistance and resistivity of ten pedicle screws (from fo...

Cu2S thin films have been prepared by vacuum evaporation method from CuS powder. Cu2S was deposited onto precleaned flat glass substrates coated under a pressure of 10 torr at an evaporation rate of 3Å /sec. The resistivity of the vacuum evaporated Cu2S thin films was measured in the temperature range 303K-453K and was found between 10 to 10 ohm cm. This low resistivity is due to degenerate nat...

High-pressure Bridgman (HPVB) and vertical zone melting (HPVZM) growth processes have been applied for the manufacturing of Cd1-xZnxTe (x = 0.04 – 0.2), CdSe and ZnSe crystal tapes with sizes up to 120×120×12 mm. The influences of the technological parameters describing the growth processes on the crystal quality and some selected material properties are discussed. The dependence of the inclusi...

The interpretation of the segment deep three-dimensional Crimean region geoelectrical model within Saki and Yevpatoria profiles, built on basis Earth's low-frequency electromagnetic field experimental observations, was obtained in 2012 by INSTITUTE OF GEOPHYSICS named after S.I.Subbotin. main result analysis is identification vertical horizontal alternation high low resistivity, both earth's cr...

Normal silicon wafer substrate resistivity ranges for CMOS technologies have typically spanned from a low of about 5 mohm-cm on heavily doped epi substrates to a high of around 30 ohm-cm on polished wafers. Although heavily doped substrates have proven useful for protection against latch-up, digital CMOS device design and performance has not been strongly coupled directly to substrate resistivi...

Studies were done on dogs in vivo to determine the effect of intracardiac blood on the electrocardiogram. By exchange transfusions of packed cells or of Rheomacrodex, hematocrit was raised to over 70% or lowered to 16%. The electrical resistivity of the blood changed accordingly from control values of 150 ohm-cm to over 500 ohm-cm or to as low as 67 ohm-cm. The x-, y-, and zvector leads were pr...

ZnO thin films with preferred orientation along the (002) plane were prepared onto the glass substrates by the sol-gel spin coating method for different post- annealing temperatures. The XRD study confirms that the thin films grown by this method have good crystalline hexagonal wurtzite structure. The optical band gap of the samples was determined from UV-visible spectra. It is found that the s...
