Atmospheric temperature affects both the absorption spectrum and the concentration of atmospheric gases. Gases with larger abundances and stronger absorption band intensities in the infrared region have a greater influence ...

The following eight oxicam structures were studied using theoretical methods, (DFT), and the Gaussian 09 program in the gaseous and aqueous phases: 4-meloxicam, droxicam, isoxicam, lornoxicam, meloxicam, normeloxicam, ...

The M06 family of density functionals was employed to calculate the molecular structure and properties of the ethambutol molecule. Besides determination of molecular structures, UV–vis spectra were computed using TD-DFT ...

The preferential conformations of a series of six–membered saturated heterocycles containing oxygen and sulfur atoms, 4-alkyl-6-methyl-1,3-dithiane, with alkyl=methyl, ethyl, propyl, isobuthyl, terbuthyl have been studied ...

The inter-cohort variability in the von Bertalanffy (VB) growth parameters of common sardine (Strangomera bentincki) was analyzed for the period between 1990 and 2007. Time series of monthly length–frequency data were used ...

Intertidal crustaceans have a high degree of physiological plasticity, which allows them to withstand periods of water emersion. In this study we examine the physiological constraints that determine the distribution and ...

A study on the reproductive biology of the Pacific butterfish, Stromateus stellatus, using samples from the coast off Biobío Region (Chile), was carried out. Samples were obtained from fishing vessels during austral ...

Codium fragile subsp. tomentosoides is an introduced macroalga on the coast of Chile. We identified and quantified the epiphytes present in basal, intermediate and apical sections of 32 thalli. The accumulation of epiphytes ...

We analysed the ecotoxicological quality of sediments in Moraleda, Puyuguapi and Elefantes Channels andvAysén Fjord, located between 44º and 46.5ºS, using non-specific tests in order to evaluate their base conditions in ...

Se caracteriza la distribución y morfología de los neuromastos en la ontogenia temprana de la anchoveta (Engraulis ringens) y sardina común (Strangomera bentincki). Aunque ambas especies comparten varias características ...
