Varieties with equationally definable factor congruences II
(Birkhauser Verlag Ag, 2017-09-25)
We study four types of equational definability of factor congruences in varieties with 0 → and 1 →. The paper completes the work of a previous paper on left equational definability of factor congruences.
Factor congruences in BCK-algebras
(Springer Verlag Berlín, 2008-07-29)
In this paper, we characterize factor congruences in the quasivariety of BCK-algebras. As an application we prove that the free algebra over an infinite set of generators is indecomposable in any subvariety of BCK-algebras. ...
Equational definability of (complementary) central elements
(World Scientific, 2016-05)
For a variety with weak existentially definable factor congruences, we characterize whenthe properties "e is a central element" and "e and f are complementary central elements"are definable by (∀ V p = q)-formulas and by ...
How far can we go in simplifying biomonitoring assessments? An integrated analysis of taxonomic surrogacy, taxonomic sufficiency and numerical resolution in a megadiverse region
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
The need for biodiversity conservation is increasing at a rate much faster than the acquisition of knowledge of biodiversity, such as descriptions of new species and mapping species distributions. As global changes are ...
The semantic congruency effect into bistable visual perception: a study based on tones of voice as top-down modulating stimuli
Background: Bistable images (or ambiguous images) have the chance to be interpreted in two
different ways. Owing to its physical features, this type of images offers two independentvisual
perceptswhich are associated ...
Decomposability of free Łukasiewicz implication algebras
(Springer, 2006-11)
Łukasiewicz implication algebras are {→,1}-subreducts of Wajsberg algebras (MV-algebras). They are the algebraic counterpart of Super-Łukasiewicz Implicational logics investigated in Komori, Nogoya Math J 72:127-133, 1978. ...
Congruence of higher education: determinants and effects of the allocation process in the labor market, applied case to Colombia
(Universidad EAFITEscuela de Economía y Finanzas, 2016-02-22)
This paper provides new evidences to the literature of assignment in the labor market for the Colombian case. Specifically it focuses on the existing relationship between acquired human capital in higher education and its ...
The effect of concept congruence on preference for culturally diverse apparel products
(Taylor and Francis Ltd., 2016-01-01)
The global market for designer apparel, especially the American market, is attractive to include in Asian designers’ internationalisation strategies. In an effort to identify factors that may impact acceptance of Asian ...

Congruência entre grupos biológicos em uma planície de inundação neotropical
(Universidade Federal de Mato GrossoBrasilInstituto de Biociências (IB)UFMT CUC - CuiabáPrograma de Pós-Graduação em Ecologia e Conservação da Biodiversidade, 2014-12-18)
The congruence analysis in communities is used for check if biological groups show the
same patterns of distribution along an environmental gradient. When occurs congruence
between groups is possible the selection of one ...
