IMPROVING THE CHEMICAL PROPERTIES OF ACIDIC SOIL WITH AFFORDABLE LIME APPLICATION FOR INCREASING POTATO GROWTH AND YIELDS IN SEDIE DISTRICT, NORTHWESTERN ETHIOPIA [PDF]
مجلة الأنبار للعلوم الزراعيةSoil acidity remains a critical issue in Ethiopia, particularly in the highland regions, where over 43% of arable lands has low pH levels. Enhancing the chemical properties of the soil and subsequent potato growth and yield through affordable lime ...

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Ground-state solutions for fractional Kirchhoff-Choquard equations with critical growth
Advances in Nonlinear AnalysisWe study the following fractional Kirchhoff-Choquard equation: a+b∫RN(−Δ)s2u2dx(−Δ)su+V(x)u=(Iμ*F(u))f(u),x∈RN,u∈Hs(RN),\left\{\begin{array}{l}\left(a+b\mathop{\displaystyle \int }\limits_{{{\mathbb{R}}}^{N}}{\left|{\left(-\Delta )}^{\frac{s}{2}}u\right|}

pH‐mediated activation of the lysosomal arginine sensor SLC38A9
FEBS Letters, EarlyView.Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Fractional Long-Range Dependence Model for Remaining Useful Life Estimation of Roller Bearings
Fractal and FractionalEstimation of remaining useful life (RUL) of roller bearings is a prevalent problem for predictive maintenance in manufacturing. However, roller bearings are subject to a variety of factors during their operation.

Experimental Biology and Medicine, 1971 SummaryMannide monooleate and mannide dioleate fractions were obtained by vacuum distillation and column chromatography of Arlacel A. Different densities, stabilities, and different toxicities were found. The monooleate fraction was readily hydrolyzed by pancreatic lipase with consequent release of free oleic acid and it exhibited also severe tissue ...

Diffusive representations for fractional Laplacian: systems theory framework and numerical issues [PDF]
, 2009 Bridging the gap between an abstract definition of pseudo-differential operators, such as (-\Delta)^{\gamma} for - 1/2 < \gamma < 1/2, and a concrete way to represent them has proved difficult; deriving stable numerical schemes for such operators is not ...
