Nutritional Potential, Phytochemical Content, In Vivo Antioxidant, and Antanemic Potential of Musa paradisiaca Flower

Food Chemistry International, EarlyView.
After collecting Musa paradisiaca leaves, some were dried and others were used to produce aqueous extracts. The extracts and powders were characterized and then administered to rats made anaemic by PHZ. After 14 days of administration of the two samples, the rats were euthanized and it was observed that after 9 days of treatment, the aqueous extract ...

Effect of hole geometry and Electric-Discharge Machining (EDM) on airflow rates through small diameter holes in turbine blade material [PDF]

The effects of two design parameters, electrode diameter and hole angle, and two machine parameters, electrode current and current-on time, on air flow rates through small-diameter (0.257 to 0.462 mm) electric-discharge-machined holes were measured.

On Gakerkin approximations for the surface-active quasigeostrophic equations

, 2015
We study the representation of solutions of the three-dimensional quasigeostrophic (QG) equations using Galerkin series with standard vertical modes, with particular attention to the incorporation of active surface buoyancy dynamics.

Move beyond free radical theory of aging

iMetaOmics, EarlyView.
Free radicals play a dual, dose‐dependent role in aging. Low levels activate the key sensor adenosine 5'‐monophosphate‐activated protein kinase (AMPK), promoting cell survival mechanisms like autophagy and enhancing mitochondrial health. High levels, however, push AMPK to initiate cell death pathways, such as apoptosis. This positions AMPK as a central

Linking Process‐Induced Degradation to Mechanical Property Deterioration in Flax Fiber–Reinforced Bio‐Polymer Matrix Composites

Polymer Composites, EarlyView.
Effect of processing‐induced thermal degradation on the mechanical performance of thermoplastic flax fiber composites. ABSTRACT The drawback of biobased polymer matrix composites (PMCs) is their limited temperature stability, resulting from degradation, which restricts their processability in established composite manufacturing processes requiring ...

2D Time-frequency interference modelling using stochastic geometry for performance evaluation in Low-Power Wide-Area Networks

, 2016
In wireless networks, interferences between trans- missions are modelled either in time or frequency domain. In this article, we jointly analyze interferences in the time- frequency domain using a stochastic geometry model assuming the total time ...
