This article describes the Quantitative structure–activity relationship models of 1-[2-hydroxyethoxy-methyl]-6-(phenylthio) thymine inhibition of the human immunodeficiency virus (HIV-1) reverse transcriptase (RT) was developed using the multi linear regressions method. These studies were...

This article describes a Group (VI) modified Co-Zr-B amorphous nano alloys were prepared in situ ultrasound-assisted reduction by sodium borohydride in an aqueous solution. Co-Cr-Zr-B, Co-Mo-Zr-B and Co-W-Zr-B powders were characterized by XRD, FESEM, BET and ICP techniques. No distinct peak...

Distillation is one of the most widely used separation units that consumes the largest amount of energy in chemical and petrochemical industries. Heat integration of thermally coupled distillation column is one of the methods to reduce energy-consumption. This paper provides a comparison between...

Nowadays, electrospinning has emerged as a widespread technology to produce nanofibers and best candidates for many significant applications. The most important challenge is to attain uniform nanofibers. In these cases, controlling the production of electrospun nanofiber becomes important....

The flow patterns and heat transfer have been studied numerically for contained air in the space formed by two vertical concentric cylinders. The inner cylinder rotates about its vertical axis and the outer cylinder is kept stationary. This geometry simulates, for example, the gaps at the ends...

Bacterial cellulose produced by Gluconacetobacter xylinus is an advantage bacterial product cause of its unique properties, could be used as an ideal dress. The aim of this study was to consider the capability of this biomaterial in release of doxycycline. Proving of this capability provided the...

Electrospinning has recently emerged as a widespread technology to produce synthetic nanofibrous and the best candidates for many important applications like scaffolds in tissue engineering. Creating porosity is the primary challenge of tissue engineering scaffolds. But, the most important...

In this study, Electrospray hydrodynamics and electrical potential dependency of heat transfer coefficient were investigated by computational fluid Dynamics (CFD). VOF method was applied to solve momentum equation of these two-phase flow and Whitaker empirical relationship for gas, liquid flow...

In this study, the effect of an applied electric field on the separation and rise of bubble was simulated by Computational Fluid dynamics and results were compared with experimental data. The numerical results showed proper agreement (10%) with experimental reports. The working fluids in the...

It determines the dimension of biomolecules that are critical to the functioning of living organisms: carbohydrates, proteins, nucleic acids. It is proved that they have a higher dimension. New image presents the structure of biomolecules, appropriate to their higher dimension, and given an...
