Spatial pattern and scale of soil N and P fractions under the influence of a leguminous shrub in a Pinus canariensis forest

open access: yes, 2009
Nitrogen-fixing plants alter the chemical properties of the soil beneath plant canopies, particularly by concentrating nitrogen-rich organic matter. We hypothesize that the presence of a legume canopy inside a plot will more greatly influence the spatial

Effect of hydrophilic / hydrophobic fractions of Natural Organic Matter on irreversible fouling of membranes [PDF]

open access: yes, 2009
Natural organic matter (NOM) has been identified as a major factor affecting membrane processes performances, but its impact is difficult to quantify from global parameters such as organic carbon content.

On the quasi-periodic $p$-adic Ruban continued fractions

open access: yes, 2022
summary:We study a family of quasi periodic $p$-adic Ruban continued fractions in the $p$-adic field $\mathbb {Q}_p$ and we give a criterion of a quadratic or transcendental $p$-adic number which based on the $p$-adic version of the subspace theorem due ...

The Changes of P-fractions and Solubility of Phosphate Rock in Ultisol Treated by Organic Matter and Phosphate Rock

open access: yesJournal of Tropical Soils, 2012
Phosphorus (P) is one of the essential elements for plant, however, its availability is mostly very low in acid soils. It is well documented that application of phosphate rock and organic matter are able to change the level of availability of P-form in ...

Measurement of the Branching Fractions B (B0 →p p ̄ p p ̄) and B (Bs0 →p p ̄ p p ̄)

open access: yes, 2023
Searches for the rare hadronic decays B-0 -> p (p) over barp (p) over bar and B-s(0) -> p (p) over barp (p) over bar are performed using proton-proton collision data recorded by the LHCb experiment and corresponding to an integrated luminosity of 9

On the eigenvalues of the p&q-fractional Laplacian

open access: yesTunisian Journal of Mathematics
We consider the eigenvalue problem for the fractional $p \& q-$Laplacian \begin{equation} \left\{\begin{aligned} (- Δ)_p^{s}\, u + μ(- Δ)_q^{s}\, u+ |u|^{p-2}u+μ|u|^{q-2}u=λ V(x)|u|^{p-2}u\quad & \text{in } Ω\\ u=0\quad& \text{in}\quad\R^N\backslashΩ, \end{aligned}\right.

Hölder regularity for parabolic fractional p-Laplacian

open access: yesCalculus of Variations and Partial Differential Equations, 2023
AbstractLocal Hölder regularity is established for certain weak solutions to a class of parabolic fractional p-Laplace equations with merely measurable kernels. The proof uses DeGiorgi’s iteration and refines DiBenedetto’s intrinsic scaling method. The control of a nonlocal integral of solutions in the reduction of oscillation plays a crucial role and ...
