The diversity of Cyanobacteria in water and sediment samples from four representative sites of the Salar de Huasco was examined using denaturing gradient gel electrophoresis and analysis of clone libraries of 16S rRNA gene PCR products. Salar de Huasco is a high altitude (3800 m altitude) saline wetland located in the Chilean Altiplano. We analyzed samples from a tributary stream (H0) and three...

The present study estimated the human daily and weekly intake of inorganic elements due to consumption of fish in Rio de Janeiro state and the associated potential health risks posed by some toxic elements. All samples analyzed had values of Cd and Pb below the Maximum Tolerable Limits of 3.0 mg kg-1 for Pb and 1.0 mg kg-1 for Cd; only Mugil cephalus, Cynoscion leiarchus and Caranx crysos had A...

The demand for “green” metals such as lithium is increasing the world works to reduce its reliance on fossil fuels. More than half of world’s resources are contained in lithium-brine deposits, including salt flats, or “salars”, Andean region South America, also known Lithium Triangle. genesis deposits largely driven by leaching from source rocks watersheds, transport via groundwater systems sal...

Background: The purpose of this study was to identify arsenite-oxidizing halobacteria in samples obtained from Salar de Punta Negra, II Region of Chile. Seven bacterial isolates, numbered as isolates I to VII, grown in a culture medium with 100 ppm as NaAsO2 (As (III)) were tested. Bacterial growth kinetics and the percent of arsenite removal (PAR) were performed simultaneously with the detecti...

En este artículo analizo el documental observacional Surire (2015) de los realizadores Bettina Perut+Iván Osnovikoff desde una perspectiva metodológica que vincula la ecocrítica con aproximación táctil a imagen cinematográfica. Este muestra, sin comentarios, entrevistas o música, vida cotidiana comunidad aimara reside en las inmediaciones del Salar Surire, un área natural protegida por Estado C...

Small improvements to the iteration procedure of the IEEE Standard 1241-2001 are suggested, and extension of the standard MATLAB program implementing the sine wave test is discussed. The program is compatible with the LabView program already announced, and in other working modes offers extensions, too.
