Heterogeneous nanofluids: natural convection heat transfer enhancement

Nanoscale Research Letters, 2011
Convective heat transfer using different nanofluid types is investigated. The domain is differentially heated and nanofluids are treated as heterogeneous mixtures with weak solutal diffusivity and possible Soret separation.

Brownian Motion and Thermophoretic Diffusion Effects on Micropolar Type Nanofluid Flow with Soret and Dufour Impacts over an Inclined Sheet: Keller-Box Simulations

Energies, 2019
The principal objective of the current study is to analyze the Brownian motion and thermophoretic impacts on micropolar nanofluid flow over a nonlinear inclined stretching sheet taking into account the Soret and Dufour effects.

Influence of heme and pH on the oligomeric states of Brucella melitensis bacterioferritin

Acta Crystallographica Section D, EarlyView.
The oligomerization of B. melitensis bacterioferritin (BmBfr) was studied using X‐ray crystallography, size‐exclusion chromatography and thermal shift analysis. These techniques allowed the characterization of both apo and holo BmBfr, highlighting the impact of heme and pH on the oligomerization mechanism.Bacterioferritin from Brucella melitensis ...

The detrimental effect of thermal exposure and thermophoresis on MHD flow with combined mass and heat transmission employing permeability

International Journal of Applied Mechanics and Engineering
We look at the viscous free-convective transitional magnetohydrodynamic thermal and mass flow over a plate that is always perforated and standing upright through permeable media while thermal radiation, a thermal source, and a chemical reaction are all ...

Numerical Solution of Casson Nanofluid Flow Over a Non-linear Inclined Surface With Soret and Dufour Effects by Keller-Box Method

Frontiers in Physics, 2019
In this article, the effects of a Casson Nanofluid boundary layer flow, over an inclined extending surface with Soret and Dufour, is scrutinized. The model used in this study is based on the Buongiorno model of the thermal efficiencies of the fluid flows

Training and validation of an automated algorithm to differentiate no and minimal diabetic retinopathy from more severe stages in wide‐field images

Acta Ophthalmologica, EarlyView.
Abstract Purpose Diabetic retinopathy (DR) is a leading cause of blindness in the working‐age population. Screening is essential to identify and treat sight‐threatening stages prior to irreversible visual loss. This study aimed to train and validate an automated algorithm to identify no or minimal DR, potentially saving resources for specialist ...

Familial Co‐Aggregation of Neurodevelopmental Conditions and Childhood‐Onset Type 1 Diabetes

Acta Paediatrica, EarlyView.
ABSTRACT Aim Childhood‐onset Type 1 diabetes (T1D) is associated with neurodevelopmental conditions (NDCs). We examined whether this association extends to relatives and assessed phenotypic, genetic, and environmental correlations between T1D and NDCs.

Afamelanotide improves quality of life and light tolerance in Austrian erythropoietic protoporphyria patients

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Background Erythropoietic protoporphyria (EPP) is a rare genetic disorder characterized by severe phototoxic reactions that occur within minutes of light exposure. In clinical studies, afamelanotide has been shown to prolong pain‐free sun exposure, improve quality of life, and reduce the frequency and severity of phototoxic reactions ...

A study on precise estimation of laminar burning velocity of lean hydrogen-air premixed flame (Effect of species diffusion models)

Mechanical Engineering Journal
Effects of species diffusion models on the laminar burning velocity SL of lean hydrogen-air premixed flame are investigated by performing one-dimensional numerical simulations of lean hydrogen-air premixed flames at an equivalence ratio of 0.5.

PEG400 regulates Falcipain 2 activity through an allosteric mechanism

The FEBS Journal, EarlyView.
Falcipain‐2 can potentially be leveraged as a drug target due to its critical role as a haemoglobinase during the intra‐erythrocytic stage of Plasmodium falciparum. Here, we investigate the regulation of the proteolytic and haemoglobinase activity of falcipain‐2 in the presence of polyethylene glycol.
