Effect of partial slip on hydromagnetic flow over a porous stretching sheet with non-uniform heat source/sink, thermal radiation and wall mass transfer

Ain Shams Engineering Journal, 2014
In this work, we have investigated the effect of partial slip on hydromagnetic boundary layer flow in porous medium over a stretching surface with space and temperature dependent internal heat generation/absorption, thermal radiation and wall mass ...

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

FEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

To the problem of non-isothermal moisture transfer in capillary-porous media

Весці Нацыянальнай акадэміі навук Беларусі: Серыя фізіка-тэхнічных навук, 2016
A mathematical model of moisture transfer in capillary-porous media is proposed. It is based on the equations of twophase filtration, isotherms of moisture sorption, thermodynamic equations of Kelvin and Klapeirone - Klausius .

Integrating Genetic Programming with Dimensional Analysis and Data-Splitting for Heat Transfer Estimation of Nanofluids

Journal of Chemical Engineering of Japan
The use of nanofluids is expected to enhance heat transfer owing to their unique thermophysical properties when used as heat media. Although there have been many reports on the construction of equations for estimating heat transfer in nanofluids, the ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Slip Effects on Boundary Layer Flow and Heat Transfer Along a Stretching Cylinder

International Journal of Applied Mechanics and Engineering, 2013
An axi-symmetric laminar boundary layer flow of a viscous incompressible fluid and heat transfer towards a stretching cylinder is presented. Velocity slip is considered instead of the no-slip condition at the boundary. Similarity transformations are used

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

FEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

The influence of return bends on the downstream pressure drop and condensation heat transfer in tubes [PDF]

, 1971
The influence of return bends on the downstream pressure drop and heat transfer coefficient of condensing refrigerant R-12 was studied experimentally. Flow patterns in glass return bends of 1/2 to 1 in. radius and 0.315 in. I. D.

Development of a heat transfer analysis program by an efficient and simplified numerical technique: Application to LNGC

International Journal of Naval Architecture and Ocean Engineering
Heat transfer analysis in ships handling LNG as cargo or fuel at extremely low temperatures has two purposes, i.e., 1) to select steel grades based on temperature distribution to protect the hull structure from extremely low-temperature cargo and 2) to ...
