The paper reports results of examining the influence of modifier admixtures on the corrosion resistance of concrete for reinforced concrete sleepers based on the criteria of electric resistance, resistance to alkaline corrosion and corrosion due to the cr... see more

To succeed in artificial insemination and to produce the fecundation in cows it isnecessary to have knowledge about optimal time of ovulation. Such possibilityappears using the values of electrical resistance of cervical mucus. The smallestvalues are obta... see more

En este artículo, se estudia la resistencia de puesta a tierra en redes urbanas de distribución eléctrica de la ciudad de Copiapó (Chile) por medio de distribuciones de probabilidad, con el objetivo de evaluar el desempeño del diseño de las mallas que act... see more

The results of the research into the electrical properties of the "water in castor oil" emulsion, which make it possible to substantiate the technology of castor oil purification from plant impurities and water in an electric field, were presented.The exp... see more

Aphis glycines Matsumura (Hemiptera: Aphididae) is a serious pest of soybean in North America. Plant resistance is a valuable tool for the management of this pest, and a better understanding of the interactions between aphid and soybeans expressing varyin... see more

The issues of calculation of electrical phenomena in multilayer carbon fiber composite materials are considered. The method for assessing the reliability of composite material models for modeling electrical phenomena in composite structures is proposed. T... see more

Highly resistive states were formed in nonhomogeneous thin La0.67Ca0.33MnO3 films at 80 K temperature after resistance switching induced by the pulsed thermocycling. Heating up to room temperature does not destroy the resistive states. They demonstra... see more

In the present study DLC:SiOx/DLC/DLC:SiOx/nSi and DLC:SiOx/DLC/DLC:SiOx/pSi structures were fabricated by ion beam deposition using a closed drift ion source. Current-voltage (I-V) characteristics of the multilayer samples were measured at room temperatu... see more

A method of structure simulation was used to investigate the influence of the hard phase quantity on parameters of the wear resistance of antifriction alloy B16. A method of optimization of linear intensity of wear depending on the quantitative correlatio... see more
