The time course for changes in food intake, body weight, plasma glucose and insulin concentrations and HOMA index was monitored over a period of 8 weeks in rats exposed from the 8th week after birth to diets containing either starch or fructose and sunflower oil. In two further groups of rats exposed to the fructose-rich diet part of the sunflower...

Based on expansions with only two coefficients and known critical points, we consider a minimal model of phenomena. The method analysis is both based inspired the symmetry properties functional self-similarity relation between consecutive approximations. Factor approximants are applied together various natural optimization conditions non-perturbative nature. role control parameter played by ind...

the alborz coal basin is located in northern part of iran. the coal deposits of shahrood in eastern alborz, zirab in central alborz and abyek in western alborz were studied as typical coalfields of the basin. shemshak formation which is the main coal-bearing sequence was formed during the triassic-jurassic in the basin. it consists of sandstone, siltstone, shale and claystone, which variedly al...

Background: Sediments in the aquatic ecosystems can be used as suitable indicators for monitoring contaminants. Then, objectives of this study were to evaluate concentration heavy metals surface sediments Mohammad Abad River, determine degree pollution using some major contamination indices; identify sources (anthropogenic or natural sources) studied metals; and “reference river” river under ec...

Copper (Cu) and cadmium (Cd) metal distribution in soil–plant ecosystems their public health risk impact on ruminants (cows, buffalo, sheep) are explored the present investigation. Five different forage crops were selected, foraging responses of three types at ecological sites evaluated. The soil these was polluted (due to wastewater irrigation) studied evaluate contamination pollution load ind...

Abstract Purpose Agricultural land use associated with intensification in plant growing affects the physicochemical parameters of soils and thus soil quality. The aim this study was to identify quality Peshok catchment Eastern Himalayas under different types (tea, horticulture, rice), high monsoon rainfall conditions. Methods Physical chemical analysis were used, e.g. bulk density, pH, TOC, maj...

In this work, the concentrations of the potentially toxic elements in stream sediments in SE Nigeria were assessed for pollution monitoring in mining, quarrying, and farming areas. The levels of iron, molybdenum, vanadium, copper, lead, zinc, nickel, cobalt, manganese, chromium, barium, and beryllium were determined. The concentrations of the elements were in the order of Fe > Ba > Mn > Cr > Zn...

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...
