Assessment of asymmetry and trajectory during repeated twenty-meter sprints in court sports wheelchair athletes

Frontiers in Sports and Active Living
IntroductionManual wheelchair (MWC) propulsion relies on upper limb power, coordination, and endurance. Propulsion asymmetry can reduce efficiency, yet the impact of fatigability on upper limb asymmetry remains underexplored.

New hybrid materials based on poly(ethyleneoxide)-grafted polysilazane by hydrosilylation and their anti-fouling activities

Beilstein Journal of Nanotechnology, 2013
The objective of this work was to develop new coating materials based on poly(ethyleneoxide) (PEO), which was grafted onto polysilazane (PSZ) by hydrosilylation. Three types of PEO with different molecular weights (350, 750, 2000 g/mol) were studied. The

On Regularity of a Weak Solution to the Navier–Stokes Equations with the Generalized Navier Slip Boundary Conditions

Advances in Mathematical Physics, 2018
The paper shows that the regularity up to the boundary of a weak solution v of the Navier–Stokes equation with generalized Navier’s slip boundary conditions follows from certain rate of integrability of at least one of the functions ζ1, (ζ2)+ (the ...

Perirenal fat thickness is associated with metabolic risk factors in patients with chronic kidney disease

Kidney Research and Clinical Practice, 2019
Background : Adipose tissue accumulation in specific body compartments has been associated with diabetes, hypertension and dyslipidemia. Perirenal fat (PRF) may lead to have direct lipotoxic effects on renal function and intrarenal hydrostatic pressure.

Achieving National Food Security in Sub‐Saharan African Countries: The Role of Foreign Agricultural Aid

Food and Energy Security, Volume 14, Issue 1, January/February 2025.
ABSTRACT African policymakers have astutely prioritized agricultural expenditure as a crucial strategy to address food insecurity in the continent. However, the available financial resources are insufficient to achieve this objective. Foreign agricultural aid has been proposed as a viable supplement to domestic resource mobilization efforts in bridging
