The concentration of selected trace metals (Fe, Cd, Cu, Pb, and Zn) in 30surface sediments were measured using Atomic Absorption Spectrometer to investigatethe spatial and seasonal variations of trace metals along Kanyakumari coast, India. Toassess the environmental risk of trace metals, enrichment factor, geo-accumulation index,pollution load index, and ecological risk index have been calculat...

oil and pollutants resulting from its extraction and exploitation are considered as one of the serious problems for human health. vast oil fields of ahvaz city located in southern iran are known as one of controversial subjects in contamination with heavy metals. in this study, oil fields' soils of ahvaz city (ab-teymour) were chemically analyzed in order to determine the concentration of eight...

the concentrations of potentially toxic elements (as, sb, and hg) and some trace elements in 36 topsoil samples and 18 agricultural soil samples were measured at the aq-darreh river watershed, nw iran. based on the results of the chemical analysis and comparing them with different standards, it seems that the soils of the aq-darreh river watershed are polluted with as and sb. this pollution res...

The contamination of riverbed sediments by heavy metals has assumedserious problems due to their toxicity and accumulative behavior. The present studyinvestigated the concentrations of heavy metals from the bottom sediments of ShitalakhyaRiver to understand the level of contamination and their distribution. The averageconcentrations of heavy metals Al, K, Ca, Mg, Fe, As, Cu, Co, Cr, and Zn are ...

Background and Aim: In recent years, the use of herbal oral care products has been taken into consideration for reducing dental plaque accumulation. Propolis has been widely used in medicine due to its multiple biological properties. The aim of this study was to evaluate the antiplaque efficacy of an herbal toothpaste containing propolis in comparison with a control group. Materials and Method...

the lipid accumulation product is a novel, safe and inexpensive index of central lipid over accumulation based on waist circumference and fasting concentration of circulating triglycerides. this study was designed to investigate the ability of lipid accumulation product to predict cardio-metabolic risk factors in postmenopausal women. in this cross-sectional study, 264 postmenopausal women by u...

Using a bibliometric approach, this paper analyzes research trends and forecasts of data mining from 1989 to 2009 by locating heading ‘‘data mining’’ in topic in the SSCI database. The bibliometric analytical technique was used to examine the topic in SSCI journals from 1989 to 2009, we found 1181 articles with data mining. This paper implemented and classified data mining articles using the fo...

carbon dioxide (co2) concentration of the global atmosphere has increased during the last decades. increasing global atmospheric co2 concentrations are expected to influence crop production. in order to evolution of co2 concentration effects on morphophysiologycal traits in tagets, ageratum and gauilardia, a factorial experiment based on completely randomized design with 3 replications and 12 t...
