Abstract

The great interest to conducting polymer composites (CPC) is connected with wide possibilities of their technical application. Low (light) specific weight, high corrosion firmness, stable working capabilities under extreme conditions are typical features of CPC, mechanical and thermal properties of which are not less significant than of traditional conducting materials. The presented work is devoted to creation and investigation of some electro-physical properties of new CPC on the basis of some silicon and carbon black fillers. It was established that the properties of CPC essentially depend not only on the selection of CPC components, but also on the technological methods of production of these conducting materials. For obtaining of CPC with desirable conducting properties the method of polymerization filling with simultaneous application of high pressures (up to 1000 MPa) at variation of temperature from range of 150 .., 250 ° C has been used. The obtained CPC materials in view of thin (0,2 ... 2 mm) sheets are characterized by anomalous dependence of electrical resistance on temperature - sharp change of electrical resistance by 3-4 orders. Our investigation shows that this change is reversing. The temperature at which the change takes place depends on pressure, applicable to the samples. It was established also that external electrical pulses might reach analogical change of the sample resistance level. We make conclusion that these CPC adsorb the electromagnetic waves in the range from some millimeters to 3-4 centimeters. Of these materials adsorption coefficients are up to 0,7. The obtained materials are flexible in wide range of temperatures (-140 ... 250 °C) and their mechanical modules are up to 10 MPa.

Abstract

The article depicts the most frequently encountered endoscopic approaches to endometriosis regarding techniques and outcomes in women with endometriosis-associated pain. It cites the results of three randomized, controlled trials which shows that the absolute benefit increase of destruction of lesions compared with sham operation in terms of proportion of women reporting pain relief was between 30% and 40%. It mentions that the woman should be referred to tertiary-care when adequate endoscopic experience is not available locally to deal with all forms of deep endometriosis.
