Least-perimeter partitions of the disk
(Real Sociedad Matemática Española, 2004)
In this work we study the isoperimetric problem of partitioning a planar disk into n regions of prescribed areas using the least-possible perimeter. We obtain the regularity conditions that must be satisfied by the ...

A characterization result for the existence of a two-phase material minimizing the first eigenvalue
(Elsevier, 2016-09-19)
Given two isotropic homogeneous materials represented by two constants 0 <α< | |, we consider here the problem consisting in finding a mixture of these materials αχω + β(1 − χω), ω ⊂ RN measurable, with |ω| ≤ κ, such that ...

Inmersiones isotrópicas pseudo-riemannianas
(2008)
La noción de inmersión isotrópica Riemanniana fue introducida por B. O Neill [O N1] quien estudió propiedades generales de esta clase de inmersiones. Estas inmersiones pueden ser consideradas como una generalización del ...

Bifurcation from zero of a complete trajectory for non-autonomous logistic PDEs
(World Scientific Publishing, 2005-08)
In this paper we extend the well-known bifurcation theory for autonomous logistic equations to the non-autonomous equation ut − ∆u = λu − b(t)u 2 with b(t) ∈ [b0, B0], 0 < b0 < B0 < 2b0. In particular, we prove the ...

The use of non-destructive testing to evaluate the compressive strength 1 of a lime-stabilised rammed-earth wall: Rebound index and ultrasonic pulse velocity
(Elsevier, 2020)
The non-standardization of rammed earth construction involves the quality control of such a technique to be so troublesome that it is generally avoided. As a possible approach to improve the mentioned quality control, this ...

Supported σ-Complexes of Li−C Bonds from Coordination of Monomeric Molecules of LiCH3, LiCH2CH3 and LiC6H5 to Mo≣Mo Bonds
(German Chemical Society, 2022)
LiCH3 and LiCH2CH3 react with the complex [Mo2(H)2(μ-AdDipp2)2(thf)2] (1⋅thf) with coordination of two molecules of LiCH2R (R=H, CH3) and formation of complexes [Mo2{μ-HLi(thf)CH2R}2(AdDipp2)2], 5⋅LiCH3 and 5⋅LiCH2CH3, ...

Synergy between gold and oxygen vacancies in gold supported on Zr-doped ceria catalysts for the CO oxidation
(Elsevier, 2015)
The CO oxidation activity of 1 wt.% gold catalysts prepared by depositionprecipitation on a series of ceria doped with Zr supports was studied. The supports (10, 25 and 50 Zr At. %) were synthesized by a pseudo sol-gel ...

Inactivation of a heterocyst-specific invertase indicates a principal role of sucrose catabolism in heterocysts of Anabaena sp.
(American Society for Microbiology, 2010)
Anabaena sp. strain PCC 7120 is a filamentous cyanobacterium that carries out N2 fixation in specialized cells called heterocysts, which exchange nutrients and regulators with the filament's vegetative cells that perform ...

Study of the dehydroxylation-rehydroxylation of pyrophyllite
(American Ceramic Society, 2010)
Pyrophyllite is a raw material of significant interest due to its large number of applications. Most of these applications require a thermal transformation of pyrophyllite; this thermal transformation implies the release ...

Prevalence and Genetic Characteristics of Staphylococcus aureus CC398 Isolates From Invasive Infections in Spanish Hospitals, Focusing on the Livestock-Independent CC398-MSSA Clade
(Frontiers Media, 2021)
Background: Livestock-associated (LA)-CC398-MRSA is closely related to pigs, being unfrequently detected in human invasive infections. CC398-MSSA is emerging in human invasive infections in some countries, but genetic and ...
