Magneto Thermal Convection in a Compressible Couple-Stress Fluid

Zeitschrift für Naturforschung A, 2010
The problem of thermal instability of compressible, electrically conducting couple-stress fluids in the presence of a uniform magnetic field is considered. Following the linearized stability theory and normal mode analysis, the dispersion relation is obtained.

Spatial biology in cancer epigenetics

Molecular Oncology, EarlyView.
Spatial epigenomics combines molecular profiling with tissue architecture to reveal how gene regulation is organized within intact tissues. In cancer, these technologies uncover the mechanisms driving tumor heterogeneity and microenvironmental interactions, opening new opportunities for biomarker discovery and precision medicine.

Investigation of combined heat and mass transfer between vertical parallel plates in a two-layer flow of couple stress nanofluid

Open Engineering, 2016
This study is an investigation of fully-developed laminar flow in a two-layer vertical channel; one part filled with couple stress nanofluid and the other part with clear couple stress fluid. The flow is examined for combined heat and mass transfer using

Systemic dysregulation of apolipoproteins in amyotrophic lateral sclerosis serum

FEBS Open Bio, EarlyView.
Amyotrophic lateral sclerosis (ALS) is a fatal disease that damages motor neurons. This study found that people with ALS show significant changes in blood fats and the proteins that carry them. Several apolipoproteins were higher, lipid balances were altered, and normal protein–lipid relationships were disrupted.

Peristaltic flow of rotating couple stress fluid in a non-uniform channel [PDF]

, 2017
An analysis has been carried out for thermal radiation effects on peristaltic activity of couple stress fluid in a non-uniform rotating channel. The velocity and thermal slip effects at the channel boundaries are considered.

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

FEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Couple stress fluids in porous circular squeeze films

Applied Mathematical Sciences, 2015
The squeeze film flow characteristics of a couple stress fluid between porous circular disks is investigated. The modified Reynold’s equation is derived using Stokes microcontinuum theory and is solved analytically. The expressions for the squeeze film pressure and the squeeze film force are obtained in terms of Fourier-Bessel series. Numerical results

The skills required for transition to university and study in biological sciences: A student perspective

FEBS Open Bio, EarlyView.
Bioscience students were asked for their opinions on the value and teaching of skills. 204 responded that teamwork, time management and study skills are necessary to reach University, that scientific writing, research, laboratory and presentation skills are taught effectively during their studies, while other skills are gained inherently through study ...

Global stability for thermal convection in a couple-stress fluid with temperature and pressure dependent viscosity [PDF]

, 2013
We show that the global nonlinear stability threshold for convection in a couple-stress fluid with temperature and pressure dependent viscosity is exactly the same as the linear instability boundary. This optimal result is important because it shows that
