A limit model for thermoelectric equations

open access: yes, 2011
We analyze the asymptotic behavior corresponding to the arbitrary high conductivity of the heat in the thermoelectric devices. This work deals with a steady-state multidimensional thermistor problem, considering the Joule effect and both spatial and ...

Weak solutions for generalized p-Laplacian systems via Young measures

open access: yesMoroccan Journal of Pure and Applied Analysis, 2018
We prove the existence of weak solutions to a generalized p-Laplacian systems in degenerate form. The techniques of Young measure for elliptic systems are used to prove the existence result.

Weak and stationary solutions to a Cahn–Hilliard–Brinkman model with singular potentials and source terms

open access: yesAdvances in Nonlinear Analysis, 2020
We study a phase field model proposed recently in the context of tumour growth. The model couples a Cahn–Hilliard–Brinkman (CHB) system with an elliptic reaction-diffusion equation for a nutrient.

Regularity theory for nonlinear systems of SPDEs

open access: yes, 2014
We consider systems of stochastic evolutionary equations of the type $$du=\mathrm{div}\,S(\nabla u)\,dt+\Phi(u)dW_t$$ where $S$ is a non-linear operator, for instance the $p$-Laplacian $$S(\xi)=(1+|\xi|)^{p-2}\xi,\quad \xi\in\mathbb R^{d\times D},$$ with

A COUPLED SYSTEM OF FUNCTIONAL DIFFERENTIAL EQUATIONS IN REFLEXIVE BANACH SPACES

open access: yes, 2017
We present an existence theorem for at least one weak solution for the coupled system of functional differential equations x ′(t) = f1(t, y ′(t)), t ∈ (0, T ], y ′(t) = f2(t, x ′(t)), t ∈ (0, T ] in reflexive Banach spaces.

Three weak solutions for a Neumann elliptic equations involving the p→(x)\vec p\left( x \right)-Laplacian operator

open access: yesNonautonomous Dynamical Systems, 2020
The aim of this paper is to establish the existence of at least three weak solutions for the following elliptic Neumann problem {-Δp→(x)u+α(x)|u|p0(x)-2u=λf(x,u)inΩ,∑i=1N|∂u∂xi|pi(x)-2∂u∂xiγi=0on∂Ω,\left\{ {\matrix{ { - {\Delta _{\vec p\left( x \right)}}

Generalised global supersolutions with mass control for systems with taxis

open access: yes, 2019
The existence of generalised global supersolutions with a control upon the total mass is established for a wide family of parabolic-parabolic chemotaxis systems and general integrable initial data in any space dimension.

Efficacy of an oral chew containing fibre and Bacillus velezensis C‐3102 in the management of anal sac impaction in dogs

open access: yesVeterinary Dermatology, Volume 36, Issue 1, Page 74-82, February 2025.
Background — Anal sac impaction is common in dogs and manual expression may be effective, yet recurrence remains a problem. To facilitate physiological emptying of the sacs, it is important to maintain a bulky stool consistency. Objectives — The study evaluated if supplementation with ProGlan, a complementary feed containing Bacillus velezensis C‐3102 ...
