Statistical processing of data was necessary to arrive at a reasonable conclusion regarding the chemical behavior of groundwater in a river basin. Multivariate analysis was done to elucidate the groundwater chemistry of a Central Kerala River basin. Hydrochemical parameters like EC, pH, TDS, TH, Ca, Mg, Na, K, Cl, F, HCO 3 +CO 3 , SO 4 , total Fe were estimated in the pre- monsoon and post-mons...
present survey studies intensity of heavy metals pollution (ca, fe, ni, cd, pb, zn, as, hg) in the sediments of bamdezh wetland. the main objective of the study is to quantify heavy metal pollution intensity in the wetland. other objectives of the study are separation of natural and anthropogenic heavy metal pollution and identification of the origin of heavy metals. results of this study shows...
The present study sought to determine the interactions between coral reefs and physicochemical properties of water (depth, temperature, salinity, turbidity, dissolved oxygen, pH, chlorophyll a, and water current velocity) and seabed type and slope in Kish Island, Iran. The study area was divided into 19 zones (eight zones with and 11 without corals). Physicochemical properties of water for each...
The proximity of Ca to the Mn cluster of the photosynthetic water-oxidation complex is demonstrated by X-ray absorption spectroscopy. We have collected EXAFS data at the Ca K-edge using active PS II membrane samples that contain approximately 2 Ca per 4 Mn. These samples are much less perturbed than previously investigated Sr-substituted samples, which were prepared after Ca depletion. The new ...
We present a large catalog of optically selected galaxy clusters from the application of a new Gaussian Mixture Brightest Cluster Galaxy (GMBCG) algorithm to SDSS Data Release 7 data. The algorithm detects clusters by identifying the red sequence plus Brightest Cluster Galaxy (BCG) feature, which is unique for galaxy clusters and does not exist among field galaxies. Red sequence clustering in c...
