(ELSEVIER SCI LTD., 2006-03-29)We report here the protective effect against piscirickettsiosis elicited in fish by a mixture of recombinant proteins. A comparative genomics strategy was used on a genomic library of Piscirickettsia salmonis in order to ...
-
(2009)Determination of fecal steroid metabolites is a noninvasive technique that characterizes the physiological state of organisms without the physiological and psychological stress of handling. Although this technique has many ...
-
(American Oil Chemists' Society, 1996)The induction periods for the peroxidation of various fish oils at 55-90°C were studied by the Rancimat test. The natural logarithms of the induction periods varied linearly with respect to temperature, with a mean coefficient ...
-
(American Chemical Society, 1999)Molecular vibrations in ammonia (NH3) and hydrogen sulfide (H2S), and internal rotations in hydrogen peroxide (HOOH), hydrogen thioperoxide (HSOH), hydrogen persulfide (HSSH), and ethylene (C2H4) are studied using ab initio ...
-
(1989)We compare values of time obtained with linear utility functions used in LOGIT and HIERARCHICAL LOGIT specifications of a nine-mode passenger choice model estimated with disaggregate data from Santiago, Chile, and find ...
-
(2007)We report the comparative structural-vibrational study of nanostructures of nanourchins, nanotubes, and nanorods of vanadium oxide. The tube walls comprise layers of vanadium oxide with the organic surfactant intercalated ...
-
(2001)Infrared (middle and far) and Raman spectroscopy were used to study the adsorption of vanadylnaphthalocyanine and vanadylporphine tetraphenyl substituted macrocycles adsorbed onto metallic surfaces. The IR spectra of the ...
-
(Springer, 2013)Rationale Neuronal nicotinic acetylcholine receptors (nAChRs) are pharmacological targets that have recently been implicated in the reinforcing effects ofmany drugs of abuse, including ethanol. Varenicline and cytisine ...
-
(Entomological Society of America, 1997)Aphid genotype has been shown to be a source of variability in the induction of phytochemical responses in wheat after aphid infestation as well as in their performance on wheat lines. Two clones of the aphid Sitobion ...
-
(2012)Phylogenetic diversity (PD) is commonly calculated by adding together the branch lengths or ages of a subset of taxa present in an area, using a single phylogeny as a backbone. However, a phylogenetic hypothesis is the ...
-
(BLACKWELL VERLAG GMBH, 2004-08)The ability to assess and respond to predation risk is a strong selective force. Detection of predators is carried out by one or more sensory modalities, but the use of chemoreception has significant advantages. This study ...
-
(Universidad de Valparaíso, 2015)The chain of islands including Desertores, Apiao and Quemchi located in the Inner Sea of Chiloé, in northern Chilean Patagonia (41°- 44°S), acts as a natural barrier for the flux of water in the north-south direction, ...
-
(National Academic Sciences, 2016)Loss of megafauna, an aspect of defaunation, can precipitate many ecological changes over short time scales. We examine whether megafauna loss can also explain features of lasting ecological state shifts that occurred as ...
-
(Elsevier, 2020)Antimicrobial compounds are found in a range of environments as pollutants. Here, we evaluated the influence of two common anions, NO3- and PO43-, on ciprofloxacin adsorption on humic acid/ferrihydrite composite (HADIG/Fh), ...
-
(Wiley, 2017)The distribution of suitable habitat influences natal and breeding dispersal at small spatial scales, resulting in strong microgeographic genetic structure. Although environmental variation can promote interpopulation ...
-
(Frontiers Media, 2022)The giant kelp Macrocystis pyrifera is a cosmopolitan species of cold-temperate coasts. Its South-American distribution ranges from Peru to Cape Horn and Argentina, encompassing a considerable temperature gradient, from ...
-
(2003)A study was performed on the variation of the electrophilicity index along the reaction path. Implications within the widely used finite difference approximation for density-functional based reactivity descriptors, their ...
-
(Elsevier Ltd, 1997)
-
(Springer, 2013)This study investigates the variations in the chemical profile, free radical scavenging, antioxidant and gastroprotective activities of licorice extracts (LE) from plants harvested during the months of February to November. ...
