DESIGN AND SYNTHESIS OF NOVEL ANTIMICROBIAL ACYCLIC AND HETEROCYCLIC DYES AND THEIR PRECURSORS FOR DYEING AND/OR TEXTILE FINISHING BASED ON 2-N-ACYLAMINO-4,5,6,7-TETRAHYDRO-BENZO[B]THIOPHENE SYSTEMS

A series of novel polyfunctionalized acyclic and heterocyclic dye precursors and their respective azo (hydrazone) counterpart dyes and dye precursors based Bird Feeder on conjugate enaminones and/or enaminonitrile moieties were synthesized.The dyes and their precursors are based on 2-cyano-N-(3-cyano-4,5,6,7-tetrahydrobenzo[b]thiophen-2-yl)-acetami

Modeling of energy production and heat transfer by carbon combustion and electrical arc is performed using Fluent computational fluid dynamic (CFD) software in this manuscript.The heat energy generated by carbon burning and electric arc radiation during combustion of the scrap in the EAO has been examined in detail.For this reason, modeling studies

The article considers the modeling of the function of investment-construction activities, which is an important theoretical and practical task.The author has reviewed the approaches of economic and mathematical modeling in this field.The use of the production function is briefly considered, and a tectological Cleanses approach is proposed as a meth

The condensation heat transfer performance outside horizontal enhanced tubes of near-azeotropic refrigerant R404A and zeotropic refrigerant R407C was investigated in this study.The experimental data were analyzed using Wilson graphical method.The results show that the coefficients of Tub Sealing Gasket condensation heat transfer outside horizontal

In the present work the effect of the use of synthetic sound during incubation in chicken of the Hampshire breed was studied.For the stimulation, an electronic sound generator with amplitude of power 1250 mV and time interval of 134 ms, 176 ms, 210 ms and 380 ms was used.The study was carried out in three experiments.In the 1 st experiment we tried
