The use of human vessels at the beginning of microsurgery training is highly recommended. But vessels with the appropriate length for training are not often obtained. Whether these vessels may be reused for training has not been reported. Accordingly, we harvested vessels from discarded tissues in lymph node dissection and demonstrated that vascular anastomosis training using the same human ves...

The article presents the results of study 14 cherry varieties on suitability fruits for freezing in sugar syrup. indicators organoleptic evaluation and some chemical fresh frozen syrup after their defrosting are reflected. research set studied has shown that cherries Volzhskaya Stepnaya, Vyanok,
 Zhagarskaya, Zarya Povolzhya, Zvezdochka, Kazdangskaya, Konfitur, Lasukha, Livenskaya, Milavit...

The plasma-activated reactive evaporation technique was used for the formation of indium-tin-oxide (ITO) films. ITO films were deposited on a heated (up to 350 °C) glass substrates using various mass ratios indium and tin. optical electrical properties determined. influence indium-to-tin ratio transmittance, bandgap, resistivity resistance investigated. bandgap increased from 3.18 3.37 eV, MIn/...

The artificial neural network with back propagation algorithm is a multi-layer feed-forward network, which suitable to study unsteady frost formation multiple factors. used layer growth on cold flat surface, where four feature variables including temperature of the velocity, relative humidity and air are adopted. experiment generates database, good for training due its fast speed high precision...

Abstract In previous studies, an air source heat pump system coupled with the liquid receiver and gas-liquid separator was proposed, which improved defrosting efficiency according to improvement of refrigerant mass flow during shortened time. this paper, exergy efficiencies loss (including endogenous exogenous loss) new are studied. They compared original by constructing advanced study model sy...

Quality characteristics of frozen cylindrical pork loin were evaluated following different tempering methods: 27.12 MHz curved-electrode radio frequency (RF) at 1000 and 1500 W, and forced-air convection (FC) or water immersion (WI) at 4°C and 20°C. The developed RF tempering system with the newly designed curved-electrode achieved relatively uniform tempering compared to a parallel-plate RF sy...

Abstract In this work, numerical and analytical solutions of heat transfer in a dielectric layer during melting the microwave field were considered. We considered solutions, where source term was obtained based on solution Maxwell equation, as well using Lambert law. The conditions applicable for allowing parametric analysis, are determined. areas application technology dielectrics, particular ...
