The Sheffer stroke operation reducts of basic algebras
Open Mathematics, 2017 In this study, a term operation Sheffer stroke is presented in a given basic algebra 𝒜 and the properties of the Sheffer stroke reduct of 𝒜 are examined. In addition, we qualify such Sheffer stroke basic algebras.

Strong endomorphism kernel property for finite Brouwerian semilattices and relative Stone algebras [PDF]
Mathematica BohemicaWe show that all finite Brouwerian semilattices have strong endomorphism kernel property (SEKP), give a new proof that all finite relative Stone algebras have SEKP and also fully characterize dual generalized Boolean algebras which possess SEKP.

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Sustainability‐oriented collaborations are inter‐organisational arrangements where the competencies of multiple companies are pooled together to tackle environmental challenges. These collaborations differ from traditional strategic alliances in that they tackle complex goals amidst greater uncertainties that extend beyond economic performance,

, 1997 . We investigate classes of Boolean algebras related to the notion of forcing that adds Cohen reals. A Cohen algebra is a Boolean algebra that is dense in the completion of a free Boolean algebra. We introduce and study generalizations of Cohen algebras:

Measures on Boolean Algebras [PDF]
, 2023 Dissertation (MSc (Mathematics))--University of Pretoria, 2023.This thesis deals with a number of related results on Boolean algebras. First, we prove the Stone Representation Theorem, which shows that every Boolean algebra is isomorphic to an algebra of

Precision Restoration to Minimize Soil Loss in a Watershed in the Atlantic Forest Domain
Land Degradation &Development, EarlyView.ABSTRACT The Turvo River Watershed, located in the Zona da Mata region of Minas Gerais and part of the Doce River Basin, faces serious problems of erosion and soil degradation, which compromise and reduce the quality of local water resources. Given this scenario, it is essential to implement environmental recovery strategies that prioritize the ...

Robust Linearization and Eigenvalue Analysis of General Complex Constrained Multibody Systems
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT The derivation of linearized equations and subsequent eigenvalue analysis is the basis for tasks such as frequency‐domain response analysis, control design, and stability assessment for mechanical systems. However, for general multibody systems with redundant or nonholonomic constraints, practical challenges persist in achieving numerically ...

Generalized join-hemimorphisms on Boolean algebras
International Journal of Mathematics and Mathematical Sciences, 2003 We introduce the notions of generalized join-hemimorphism and generalized Boolean relation as an extension of the notions of join-hemimorphism and Boolean relation, respectively. We prove a duality between these two notions.

Nonprofit Governance and Financial Stability: A Study of Government‐Funded Social Services
Nonprofit Management and Leadership, EarlyView.ABSTRACT Nonprofit social service providers are essential in delivering vital services, often with public funding. This study adopts a contingency perspective to explore the relationship between organizational governance and financial stability in publicly funded nonprofit organizations. We use a combination of comparative multilevel analysis (CMA) and
