(Taylor & Francis, 2016)The complete sequence of the mitochondrial genome for the Chilean silverside Basilichthys microlepidotus is reported for the first time. The entire mitochondrial genome was 16,544 bp in length (GenBank accession no. ...
-
(Elsevier, 2014)The southern tip of South America and Antarctica are particularly interesting due to many genera and also species currently sharing between both areas. The genus Nacella (Patellogastropoda: Nacellidae) is distributed in ...
-
(1991)A new differential pulse polarographic method is proposed for the determination of nicardipine, based on the electroactivity of the nitroaromatic group of the molecule. The proposed method is applied in the determination ...

(Universidad de Chile, 2018-10)Los sistemas altiplánicos presentan un alto de grado de endemismo como consecuencia de rápidos procesos de especiación ocasionados por el aislamiento geográfico y las características climáticas extremas. El objetivo del ...
-
(Elsevier, 2014)Consumption of psychoactive substances has been important in the lives of indigenous American people for several millennia. While numerous studies have reported the occurrence of smoking pipes at archaeological sites, ...
-
(Academic Press, 2013)The consumption of plant-derived hallucinogenic substances through smoking and snuffing is a long-standing tradition in the south-central Andes. Chemical and archaeobotanical evidence point to the consumption of nicotine ...
-
(MDPI, 2020)Zebrafish is becoming a popular animal model in neuropharmacology and drug discovery, mainly due to its ease of handling and low costs involved in maintenance and experimental work. This animal displays a series of complex ...
-
(Universidad de Chile., 2008)En especies eusociales de Hymenoptera, las hembras son mas tolerantes hacia compañeras de nido que hacia no compañeras de nido, en tanto en especies solitarias las hembras son agresivas hacia cualquier hembra conespecifica, ...

(ELSEVIER, 2011-03-15)This paper deals with two varieties of commutative non-associative algebras. One variety satisfies L(x)(3) + L(x)(3) = 0. The other variety satisfies L(x)(3) = 0. We prove that in either variety, any finitely generated ...

(2011)This paper deals with two varieties of commutative non-associative algebras. One variety satisfies Lx3+Lx3=0. The other variety satisfies Lx3=0. We prove that in either variety, any finitely generated algebra is nilpotent. ...
-
(Springer, 2020)By one hand, we continue with the study of the liaison between the almost Hurwitz vector fields and density functions. In particular by using mapsHwith nilpotent JacobianJHsuch that their rows are linearly dependent over ...
-
(ELSEVIER SCIENCE INC, 2005-02-01)We prove some results about nilpotent linear transformations. As an application we solve some cases of Albert's problem on the solvability of nilalgebras. More precisely, we prove the following results: commutative ...
