A Procedure for Factoring and Solving Nonlocal Boundary Value Problems for a Type of Linear Integro-Differential Equations

Algorithms, 2021
The aim of this article is to present a procedure for the factorization and exact solution of boundary value problems for a class of n-th order linear Fredholm integro-differential equations with multipoint and integral boundary conditions.

Free Surface Waves in Electrohydrodynamics With a Prescribed Vorticity Distribution

Mathematical Methods in the Applied Sciences, Volume 49, Issue 7, Page 7068-7081, 15 May 2026.
ABSTRACT Traditionally, the study of free surface flows assumed irrotationality to simplify matters, and the results seemed to have great success, notably with the Korteweg‐de Vries(KdV) equation. In the past decade, there have been attempts to remove this seemingly strong condition and replace it with a global constant vorticity equivalent to a linear

Effects of Diet Composition and Yeast Cell Wall Supplementation on Ruminal Fermentation, Gas Kinetics, Methane Production and Digestibility Assessed In Vitro Using Gas Production and DaisyII Incubator Systems

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
This study evaluated the effects of yeast cell wall (YCW) supplementation in diets with varying roughage‐to‐concentrate (R:C) ratios using in vitro techniques. The results demonstrated that YCW supplementation significantly reduced total gas and methane production, particularly in high‐roughage diets, without compromising dry matter digestibility or ...

A novel fractional structure of a multi-order quantum multi-integro-differential problem

Advances in Difference Equations, 2020
In the present research manuscript, we formulate a new generalized structure of the nonlinear Caputo fractional quantum multi-integro-differential equation in which such a multi-order structure of quantum integrals is considered for the first time.

Distributed-order fractional wave equation on a finite domain. Stress relaxation in a rod

, 2010
We study waves in a rod of finite length with a viscoelastic constitutive equation of fractional distributed-order type for the special choice of weight functions.

Sustainability in Managed Aquifer Recharge Projects: A Case Study of Three European Union Funded Projects

World Water Policy, Volume 12, Issue 2, May 2026.
ABSTRACT Managed aquifer recharge (MAR) is presented as a water management approach that fits well within the broad sustainability agenda. Three European MAR projects' outcomes were analyzed to assess how these projects interpret sustainability. This article argues that MAR projects are pushed to a narrow interpretation of sustainability by funder ...

Solving system of integro differential equations using discrete adomian decomposition method

Journal of Taibah University for Science, 2019
In this paper, we propose a new numerical method for solving system of integro-differential equations featuring Volterra and Fredholm integrals. The proposed method depends on the successful application of the Discrete Adomian Decomposition Method (DADM)

BIEN: A biodiversity informatics ecosystem advancing open and reproducible workflows for plant observation, plot and trait data

Methods in Ecology and Evolution, Volume 17, Issue 5, Page 1556-1584, May 2026.
Abstract The rapid expansion of biodiversity data presents new opportunities to understand and forecast biosphere dynamics. However, disparate and dispersed data, taxonomic and geographic inconsistencies, pervasive quality issues, and a lack of reproducable workflows hinder synthesis, introduce biases and limit accurate assessment of biodiversity ...
