(1988)A normal coordinate analysis has been carried out for the series Cs2NaLnCl6, where Ln represent a trivalent lan thanide cation such as Pr+ 3, Sm+3, Eu+3, Tb+ 3, Ho+3and Tm+3by using a general valence force field (GVFF). A ...
-
(American Physical Society, 2015)The Ehrenfest urn model is extended to a complex directed network, over which a conserved quantity is transported in a random fashion. The evolution of the conserved number of packets in each urn, or node of the network, ...
-
(1976)Following treatment for premature ejaculation, 23 males provided reports of sexual intercourse with females other than the one who had been a treatment partner. Analysis of the data strongly suggests that concomitant ...

(2007)We study commutative algebras which are generalizations of Jordan algebras. The associator is defined as usual by (x, y, z) = (x y)z - x(y z). The Jordan identity is (x2, y, x) = 0. In the three generalizations given below, ...
-
(Kluwer Academic Publishers, 2014)Flowers that are pollinated both during the day and at night could exhibit two different groups of pollinators and produce two different sets of attractants and rewards. We explored the patterns of emission of flower scents ...
-
(2007)Dendritic cells (DCs) are professional antigen presenting cells with the ability to induce and regulate an immune response. DCs that capture and present antigen under noninflammatory conditions maintain an immature phenotype ...

(Company of Biologists Ltd, 2018)© 2018. Published by The Company of Biologists Ltd. Xenografts of the hematopoietic system are extremely useful as disease models and for translational research. Zebrafish xenografts have been widely used to monitor blood ...
-
(2005)Protein kinase CK1 denotes a family of pleiotropic serine/threonine protein kinases implicated in a variety of cellular functions. Typically, CK1 acts as a 'phosphate-directed' kinase whose targeting is primed by a single ...
-
(Public Library Science, 2015)The extreme dependence on external oxygen supply observed in animals causes major clinical problems and several diseases are related to low oxygen tension in tissues. The vast majority of the animals do not produce oxygen ...
-
(2009)Background: Morphogenetic events that shape the Drosophila melanogaster embryo are tightly controlled by a genetic program in which specific sets of genes are up-regulated. We used a suppressive subtractive hybridization ...
-
(Magnolia Press, 2017)The genus Ectinogonia Spinola, 1837 is a genus mainly found in Chile; it currently contains 17 species. Recent exploration in the Andes Mountain Range of the Bio Bio Region in Chile have resulted in the collection of ...
-
(Taylor & Francis, 2017)Background: Reductions of genetic diversity and phenotypic changes in invasive plants are often observed to occur at high elevations. Genetic/phenotypic changes of invasive plants along elevation help to understand mechanisms ...
-
(2012)Mussels are one of the most cultivated and commercialized bivalves worldwide and in southern Chile its culture represent an important economic activity. The species identification within the Mytilus genera, by morphological ...

-
(2004)The tobacco-feeding race of Myzus persicae (Sulzer), formerly known as M. nicotianae Blackman, was introduced into Chile during the last decade. In order to evaluate the genetic diversity and insecticide resistance status ...
-
(2012)The Chilotan Archipelago and surrounding areas of north-western Patagonia (41°–43°S, 72°–74°W) offer a unique opportunity to study the interplay between the recent genetic and paleoenvironmental evolution on temperate ...

(Elsevier, 2014)Although Phaseolus vulgaris L. is native from the Americas and is currently cultured in diverse areas, verylittle is known about the diversity of symbiotic nitrogen fixing Rhizobium (mycrosymbiont) in many ofthose cultures. ...
-
(Sociedad Espanola de Microbiologia, 2013)Decreasing quality of forest habitats is among the major factors leading to a loss of epiphytic lichen diversity. However, there is little information about how this factor influences the diversity of terricolous lichens, ...
-
(2012)Premise of the study: The temperate forests of southern South America were greatly affected by glaciations. Previous studies have indicated that some cold-tolerant tree species were able to survive glacial periods in ...
