Effect of nitrogen and potassium fertilization on the production and quality of oil in jatropha curcas l. under the dry and warm climate conditions of colombia
(Universidad Nacional de Colombia, Facultad de Agronomía, Centro Editorial, 2014-08-11)
This study was conducted to assess fruit and seed yield, oil content and oil composition of Jatropha curcas fertilized with different doses of nitrogen and potassium in Espinal (Tolima, Colombia). The yields ranged from ...
Dietary and isotopic specialization: The isotopic niche of three cinclodes ovenbirds
(2009)
By comparing the isotopic composition of tissues deposited at different times, we can identify individuals that shift diets over time and individuals with constant diets. We define an individual as an isotopic specialist ...
Methoxycarbonylation of Styrene Using a New Type of Palladium Complexes Bearing P,N-donor Ligands as Catalysts
(Springer, 2015)
Palladium complexes of the type [Pd(L)Cl(PPh3)]Cl (L = 2-diphenylphosphinoamino)pyrimidine, or 2-diphenylphosphinoaniline), generated in situ by addition of one equivalent of PPh3 to the corresponding neutral complexes ...
Blue-Fluorescent Probes for Lipid Droplets Based on Dihydrochromeno-Fused Pyrazolo- and Pyrrolopyridines
(Wiley-VCH Verlag, 2018)
© 2018 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim Lipid droplets (LDs) have been recognized as highly dynamic cellular organelles involved in important biological functions for the survival of organisms such as supplying ...
Isotopic ecology and human diets in the forest–sseppe ecotone, Aisén Region, Central-Western Patagonia, Chile
(Wiley, 2014)
This work aims to build a comprehensive isotopic ecology with the ultimate purpose of assessing long-term
human diet decision-making by means of stable isotope analysis. We present a set of δ13Ccollagen and
δ15Ncollagen ...
Physiological and biochemical responses to dietary protein in the omnivore passerine Zonotrichia capensis (Emberizidae)
(ELSEVIER SCIENCE INC, 2004-02)
We studied the physiological, biochemical and morphological responses of the omnivore sparrow Zonotrichia capensis, a small opportunistic passerine from Central Chile acclimated to high- and low-protein diets. After 4 weeks ...
Exploring the structural controls on helium, nitrogen and carbon isotope signatures in hydrothermal fluids along an intra-arc fault system
(Elsevier, 2016)
There is a general agreement that fault-fracture meshes exert a primary control on fluid flow in both volcanic/magmatic and geothermal/hydrothermal systems. For example, in geothermal systems and epithermal gold deposits, ...
O-antigen expression in Salmonella enterica serovar Typhi is regulated by nitrogen availability through RpoN-mediated transcriptional control of the rfaH gene
(SOC GENERAL MICROBIOLOGY, 2002-12)
The authors previously reported increased expression of the Salmonella enterica serovar Typhi (S. typhi) rfaH gene when the bacterial cells reach stationary phase. In this study, using a lacZ fusion to the rfaH promoter ...
Feasibility of the use of chilean nitrate as a nitrogen source for the growth of Chlorella pyrenoidosa
(1972)
Potassic Chilean nitrate, a cheap natural product of northern Chile, was found to support the growth of the unicellular green alga Chlorella pyrenoidosa, a possible sheep fodder supplement in this region. Comparisons with ...
