Evaluation of Different Methods for Determining the Entrance Pressure Drop in Capillary Rheometry

open access: yesApplied Rheology, 2008
Two approaches for determining the entrance pressure drop in capillary rheometry were compared with low-density polyethylene and polystyrene melts as test fluids. Direct measurements with the orifice die were found to yield higher values for the entrance

Experimental Signature of Entrance Channel Effect for Mass Region A ∼ 200 [PDF]

open access: yesEPJ Web of Conferences
Entrance channel effects on heavy ion fusion dynamics have been investigated through measurements of evaporation residue (ER) cross sections and ER-gated spin distributions for the reactions 48Ti + 160Gd and 30Si + 178Hf, both leading to the formation of

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

open access: yesFEBS 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 ...

Numerical and Experimental Study to Predict the Entrance Length in Pipe Flows

open access: yesJournal of Applied Fluid Mechanics, 2019
Here, a steady, incompressible and isothermal flow in the inlet region of a circular pipe were numerically and experimentally studied to predict the entrance length. The region in the upstream of fully developed pipe flow is referred to as the developing

The risk for psychiatric disorders in offspring from thrombosis-prone pedigrees in Sweden: a nationwide family study

open access: yesResearch and Practice in Thrombosis and Haemostasis
Background: Psychiatric disorders have been associated with venous thromboembolism (VTE). However, to our knowledge, no nationwide study has examined the familial association between VTE and psychiatric disorders.

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

open access: yesFEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Analytical solution and numerical approaches of the generalized Levèque equation to predict the thermal boundary layer

open access: yesACI Avances en Ciencias e Ingenierías, 2019
In this paper, the assumptions implicit in Leveque's approximation are re-examined, and the variation of the temperature and the thickness of the boundary layer were illustrated using the developed solution.

ENTRANCE REGION FLOW OF A CASSON FLUID IN A STRAIGHT CHANNEL

open access: yes, 1992
The entrance region flow of a Casson fluid in a straight channel has been investigated numerically without making prior assumptions on the form of velocity profile within the boundary layer region, which is determined by a cross-sectional integration of ...

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

open access: yesFEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.
