dc.description.abstractAn attempt to prepare a metalorganic precursor of gallium with reactivity at low temperature in chemical vapor deposition (CVD) systems was done by reacting N-methylpyrrolidine with metal gallium or gallium nitrate under mild conditions. The precursors were bubbled into a CVD assemblage and then reacted with ammonia at temperatures between 400 and 700 °C. The depositions onto silicon substrates were pyramidal particles of 100 nm width at the base and up to 55 nm in height. The rise in growth temperature increased particle density from 0.9 to 27.1 particles per square micron, but reduced the height from 50 to 10 or 2 nm. XPS spectra showed the presence of gallium and nitrogen. The intensity of the gallium spectrum decreased as the process temperature increased indicating that GaNx particles were deposited rather than the stoichiometric gallium nitride (GaN). An additional N1s band of impurities appeared whose intensity increases with the reaction temperature. The lower impurity content corresponded to the sample prepared with Ga(NO 3)3 at 400 °C.

We sampled at sites that differed in edaphic characteristics and vegetation structure, in the wet and dry seasons of 2003 and 2004. As a population estimator we used the number of individuals captured in each sampling period. We captured 414 individuals of 12 species of Heteromyidae and Muridae. We concluded that 1) rodent communities were different among sites as a function of vegetation structure, and varied notably between grassland and adjacent shrublands: 2) such communities reflected the vegetation mosaic more than season of the year: 3) the three shrubland types maintained their identity throughout the year; y 4) low precipitation and/or grazing, through the reduction of plant cover, on gypsophilous soils afected the rodents.",,,,,,,,,"http://hdl.handle.net/20.500.12104/43158","http://www.scopus.com/inward/record.url?eid=2-s2.0-45149112520&partnerID=40&md5=3aff8c7578ebb480a68b64e82d3e0ff2",,,,,,"1",,"Revista Mexicana de Biodiversidad",,"197

dc.description.abstractMadrid, J.A.",,"2010",,"Octodon degus, a mainly diurnal rodent, characterized by its ability to shift to a nocturnal locomotor pattern under laboratory conditions, was studied to determine whether restricted food access during the scotophase could induce nocturnalism. To address this question, wheel running activity, feeding, and body temperature rhythms were analyzed for diurnal degus housed with a wheel and subjected to either long (12h) or short (2h) food availability periods, in the latter case with random or scheduled food access times. The results show that allowing nocturnal feeding for 2h, but not 12h, can shift a previous diurnal phase preference for wheel running activity and body temperature to the scotophase, with random feeding being more effective than scheduled food availability. However, this behavioral inversion proved to be unstable, as the degus returned to the diurnal phase within only a few days after the restricted feeding was discontinued. In addition, the negative masking effect induced by light, which is characteristic of the degus' nocturnal chronotype, was not observed when the animals were forced to feed at night. Thus, neither long, short, random, nor scheduled food-availability during the scotophase was able to induce all the characteristics of the nocturnal chronotype in Octodon degus. " Informa UK Ltd.
