Phytoplankton as trophic descriptors of a series of Mediterranean reservoirs (Catalonia, Spain)
(2017-12-01)
The aim of this work was to determine the ways in which the associations of phytoplankton (species, classes, and functional groups) responded to different trophic states in a series of Mediterranean reservoirs (La Llosa ...
Jordan Gradings on Associative Algebras
(SPRINGER, 2011)
In this paper we apply the method of functional identities to the study of group gradings by an abelian group G on simple Jordan algebras, under very mild restrictions on the grading group or the base field of coefficients.

Psychophysical power functions for apparent area in perceptive, memory, and inference conditions for observers of different age groups
(Perceptual Motor Skills, 2000-12-01)
The purpose of this research was to verify the effect of age on the exponent of the power function in Perceptive, Memory, and Inference experimental conditions. In the Memory condition the intervals of 2 min., 8, 24, and ...

Shift-modulation invariant spaces on LCA groups
(Polish Academy of Sciences. Institute of Mathematics, 2012)
A (K,Λ) shift-modulation invariant space is a subspace of L2(G) that is invariant under translations along elements in K and modulations by elements in Λ. Here G is a locally compact abelian group, and K and Λ are closed ...
Using functional approaches to study phytoplankton communities in a temperate region exposed to tropical species dispersal
(Springer, 2012-10)
Functional characteristics play an important role in shaping phytoplankton distributions. This approach can help to explain the success of tropical taxa in temperate ecosystems. We used functional groups (FG) and functional ...
Lead biosorption onto waste beer yeast by-product: a means to decontaminate effluent generated from battery manufacturing industry

Building of a sulfonyl-group-functionalized monomer whose polymer is able to catalyze biodiesel formation
(Wiley, 2015-02)
A linear polymer containing sulfonyl groups was synthesized from a vinyl monomer to use its acid group as a catalyst of the esterification of oleic acid to form biodiesel. First, synthesis optimization of the monomer was ...
