the objective of this study was to explore the application of hybrid artificial neural network methods to predict heavy metals in rainwater based on major elements. measurements of the heavy metals pb, cu, zn, as, ni, hg, and fe in soluble rain fractions were performed in rainwater collected at the arak plain during the rainy seasons of 2012. in the soluble fractions, the concentrations of the ...

Considering the benefits of home literacy environment for children, this study aims to develop a tool measure early opportunities provided by families their children. As result Exploratory Factor Analysis, eigenvalue scale is composed four factors and 11 items, it represents 21.73 % total variance in first factor, 20.75% second 16.65% third factor 15.33 fourth factor.

PURPOSE To evaluate the contamination index of metals and pesticides in pregnant women, and to relate this to perinatal outcomes. METHODS Descriptive, retrospective, exploratory study, developed from existing secondary data analyses at Level III maternity center. A total of 40 mothers with their newborns (NB), living in a rural area in Botucatu- Brazil and surrounding region. Blood samples fr...

Fresh water scarcity is considered a significant component, and potentially one of the most critical, global climate change. With rapid development industry, there an increasing risk freshwater contamination by heavy metals (HMs). The danger HM pollution also attributed to their accumulation, which can subsequently become source secondary in aquatic environments. In Lake Gusinoe basin, located ...

Including a method factor on which all items loaded significantly improved fit of CFAs of both IPIP and NEO-FFI data. Fit was further improved by separating the method factor into two factors representing construct-positive and construct-negative items. The criterion-related validity of conscientiousness increased when uncontaminated by method bias. PRESS PARAGRAPH This research extends previou...

Amount of pollution radiation in foodstuffs and feedstuffs are very necessary to measure because it is a direct contact with human animal health. Therefore, the present investigation useful for health environmental data base. The study included measurement effective radium-226 content (CRa) some chosen samples vegetables fruits (local imported) Najaf governorate. CRa were measured using Solid S...

This paper presents a study to calculate Pathlossusing “RF link budget analysis model” with a primary focus on a sub urban macrocell environment to calculate the pathloss during the propagation and to calculate the received signal power at receiver end and accordingly a correction factor factor will be introduced for suburban area in cost-231 hatamodel. Correction factor which is considered as ...

Background & Aims of the Study: Aquatic macrophytes, given their rapid growth and high bio mass production, great potential to accumulate heavy metals in their organs. Phragmites australis as a hyper-cumulative plant plays an important role in the bioremediation. The Badavar River of Noorabad, Lorestan province, is exposed to urban wastewater and agricultural runoffs. In order to heavy metals (...
