When studying the temperature dependences of the acoustic absorption and the modulus of elasticity, absorption peaks are often observed, which correspond to the characteristic step on the temperature dependence of the modulus of elasticity. Such features ... see more

The of electrons mobilities adjusted for critical experimental results of the Mo and Mo-Re alloys Hall effect measurements [1] were used for the calculation temperature dependence energy of the Mo electronic spectrum. It was shown that the temperature of ... see more

El RD 853/2021, de 5 de octubre, por el que se regulan los programas de ayuda en materia de rehabilitación residencial y vivienda social del Plan de Recuperación, Transformación y Resiliencia, ha puesto a disposición de los propietarios de viviendas y edi... see more

The problems analyzed in this research are the kinds and compositions of radioisotope and other elements within the mineral samples in the West Timor Island. The purposes of the research: 1) to investigate and determine the kinds of radioisotope in the mi... see more

The prototype of Bonner sphere neutron spectrometer of activation type has been created. It is composed of 5-polyethylene spheres with a diameter from 9.0 to 24.5 cm. Indium as activated material inside these spheres is used. We tested the neutron spectro... see more

In this paper, we focus on cooperative spectrum sensing (CSS) for double threshold improved energy detector. In this method, the improved energy detector compares positive power operation p of the amplitude of received signals at each secondary user (SU) ... see more

The shelf life of a composite solid propellant is one of the critical aspects for the usage of solid propellants. To assess the ageing behavior of the composite solid propellant, the activation energy is a key parameter. The activation energy is determine... see more

This paper shows the applied voltage effect on the superconductor substrate sample. The substrate temperature (Ts) increases the activation energy of the substrate atoms. Thus, the injecting of minority carriers (holes) increased in ZnO semiconductor. The... see more
