(Springer Verlag, 2017)© 2016, Springer-Verlag Berlin Heidelberg. Antarctica is considered one of the most extreme environments on Earth because of its low temperatures, dryness, high incidence of solar radiation and low nutrient availability. ...
-
(Springer Verlag, 2016)© 2016, The Author(s). Studies of different hypersaline systems have revealed various types of limitation. We evaluated the phototrophic microbial assemblages over a whole seasonal cycle (wet vs dry) in the Salar de Alconcha, ...
-
(Springer Verlag, 2017)© 2016, Springer-Verlag Berlin Heidelberg. The understanding of the spatial and temporal patterns in land use and land cover (LULC) change is a key issue for conservation efforts. In the Chilean hotspot, different studies ...
-
(Taylor and Francis Ltd., 2017)© 2016 Informa UK Limited, trading as Taylor & Francis Group.Two unusual caprolactam alkaloids, 3-(dimethylamino)hexahydro-2H-azepin-2-one and 3-(methylamino)-hexahydro-2H-azepin-2-one, were isolated from the aerial parts ...
-
(Society for Neuroscience, 2016)© 2016 the authors. Rab35 is a key protein for cargo loading in the recycling endosome. In neuronal immortalized cells, Rab35 promotes neurite differentiation. Here we describe that Rab35 favors axon elongation in rat ...
-
(Scholars Research Library, 2016)We employed a formal QSAR method to find the main interactions regulating the variation of the ability to inhibit the germination of Lactuca sativa seeds by a small group of phenolic acids. The same techique was employed ...
-
(1990)The IR spectra of nitrobenzene-do and -ds were recorded in gas and liquid phases at 25° C and in amorphous solid phase at -170°C. The appearance of new bands and intensity changes going from liquid to solid phase spectrum, ...
-
(Sociedad Chilena de Pediatria, 2016)© 2016 Sociedad Chilena de Pediatría. Children with special health care needs" (CSHCN) is an emerging and heterogeneous group of paediatric patients, with a wide variety of medical conditions and with different uses of ...
-
(Taylor and Francis Inc., 2016)© 2016, Copyright © Taylor & Francis Group, LLC. The natural dyes lawsone and plumbagin (1,4-naphthoquinones) were studied by using fluorescence, Raman, infrared (IR), surface-enhanced Raman scattering (SERS), and ...
-
(Springer Tokyo, 2016)© 2016, Springer Japan. The study of the yeasts that inhabit cold environments, such as Antarctica, is an active field of investigation oriented toward understanding their ecological roles in these ecosystems. In a great ...
-
(1992)A comparison of some structural aspects of these complexes with Cp Re(CO)3 are also discussed. Additionally, the preparation and characterization of the trimethyl phosphite derivative is reported. A complete vibrationalassignment ...
-
(Research Journal of Pharmaceutical, Biological and Chemical Sciences, 2016)Allelopathic effects of a chemical compound strongly depends on the target species, dose or concentration employed, structure of the molecule and physical properties, such as water solubility, lipophilicity and others. In ...
-
(1992)S-O stretching force constants in a series of synmetrical sulfoxide compounds were calculated from quantum chemical methods. Molecular geometries were obtained from experimental data and from MNDO and PM3 calculations. S-O ...
-
(Scholars Research Library, 2016)An analysis of the relationships between electronic structure and the inhibition of the kinase activity of VEGFR-2 was carried out for a series of 1-(4-((2-oxoindolin-3-ylidene)amino)phenyl)-3-arylureas. A similar study ...
-
(BioMed Central Ltd., 2016)© 2016 Mardones et al. Background: In the adult hippocampus new neurons are continuously generated from neural stem cells (NSCs) present at the subgranular zone of the dentate gyrus. This process is controlled by Wnt ...
-
(American Chemical Society, 2003)In this paper we describe a method to obtain estimates of the relative nucleophilicity for a series of neutral and charged electron donors from their solution phase ionization potential (Is). The relationship between ...
-
(Springer Verlag, 2014)© 2014, Springer-Verlag Berlin Heidelberg.The mechanism of Menshutkin reaction, NH3 + CH3Cl = [CH3–NH3]+ + Cl-, has been thoroughly studied in both gas and solvent (H2O and cyclohexane) phase. It has been found that solvents ...
-
(John Wiley and Sons Ltd, 2004)Theoretical electrophilicity and nucleophilicity scales, defined in terms of electronic reactivity indices, were tested for the reaction of a series of carbonates with neutral and charged reagents of varying nucleophilicity. ...
-
(American Chemical Society, 2001)A thorough quantitative analysis of the HSAB principle is performed. Complex formation reactions of a typical soft acid, Ag+, and typical hard acid, HF, with the bases XH3 (X = N, P, As) are studied using the DFT/B3LYP ...
-
(1994)A Kohn-Sham (KS) like formalism for the calculation of solvation energies of singly charged ions is presented. The approximate theory is based on a simple model that represents embedding an atomic ion into a polarizable ...
