P]O in different subcellular fractions of hepatocytes

, 1986
Nuclear, chromatin and microsomal fractions were isolated from hepatocytes prepared from rats injected with [32P]O4(2-) and killed subsequently at times between 1 and 48 h.

Dinámica de las formas del P en suelos de la región sudoeste Pampeana: Estudio de la incubación con fertilizante fosfatado

Ciencia del Suelo
Las distintas formas de P en el suelo se encuentran en equilibrio dinámico, dependiente del ambiente edáfico (textura, materia orgánica y el pH) y del manejo agronómico (como la rotación de cultivos y la fertilización).

Mechanistic insights into phosphorus transformation mediated by Arthrobacter and Sordariomycetes under long-term high-volume swine manure application in a wheat-rice rotation system

Frontiers in Microbiology
IntroductionUnderstanding the impacts of sustained high-input swine manure on soil phosphorus (P), along with identifying and functionally characterizing P-associated microorganisms, can provide a scientific foundation for effective management of soil P ...

Eigenvalues homogenization for the fractional \(p\)-Laplacian

Electronic Journal of Differential Equations, 2016
In this work we study the homogenization for eigenvalues of the fractional p-Laplace operator in a bounded domain both with Dirichlet and Neumann conditions. We obtain the convergence of eigenvalues and the explicit order of the convergence rates when periodic weights are considered.

Differential Responses of Soil Phosphorus Fractions to Nitrogen and Phosphorus Fertilization: A Global Meta‐Analysis

Global Biogeochemical Cycles
Anthropogenic inputs of nitrogen (N) and phosphorus (P) to terrestrial ecosystems alter soil nutrient cycling. However, the global‐scale responses of soil P fractions to N and P inputs and their underlying mechanisms remain elusive. We conducted a global

Studies of the distribution and bioavailability of soil zinc fractions

, 1991
This investigation was undertaken to study the distribution and availability of Zn in different soil fractions. The proportions of total Zn present in the soils in exchangeable, organically bound, complexed or adsorbed and residual fractions were ...

Supporting Student’s Thinking In Addition Of Fraction From Informal To More Formal Using Measuring Context [PDF]

, 2011
One of reasons why fractions are a topic which many students find difficult to learn is that there exist many rules calculating with fractions. In addition, students have been trained for the skills and should have mastered such procedures even they do ...

Calderón–Zygmund Estimates for the Fractional p-Laplacian

Annals of PDE
Abstract We prove fine higher regularity results of Calderón-Zygmund-type for equations involving nonlocal operators modelled on the fractional p-Laplacian with possibly discontinuous coefficients of VMO-type. We accomplish this by establishing precise pointwise bounds in terms of certain fractional sharp maximal functions.

Acidification-driven soil phosphorus fractionation following long-term fertilization and cessation at ukulinga mesic grassland in South Africa

Scientific Reports
Long-term fertilisation can alter soil nutrient dynamics, yet the persistence and redistribution of phosphorus (P) fractions following the cessation of combined nitrogen (N) and P inputs remain poorly understood. This study investigated how 71 years of P-
