Proximity to road traffic involves higher health risks because of atmospheric pollutants. In addition to outdoor air, indoor air quality contributes to overall exposure. In the framework of the BREATHE study, indoor and outdoor air pollution was assessed in 39 schools in Barcelona. The study quantifies indoor and outdoor air quality during school hours of the BREATHE schools. High levels of fin...
One of the silver resources is Cu-Mo porphyry deposits, producing silver as by product. For this research, the results of analysis of 607 lithogeochemical samples for W, Zn, Ag, As, Ba, Co, Cu, Mo, Pb, Sb, Sn, Sr, Bi elements were used to investigate geochemical behavior of silver element in Hararan area which is located in the southeast of Iran and consists of copper mineralization seems to b...
In the conversion process of lignocellulose into fuel ethanol, the enzymatic hydrolyzed or fermented lignocellulosic residues are produced as byproducts. In order to further recycle these byproducts, this study used the enzymatic hydrolyzed residues of sugarcane bagasse (EHRSCB) as the media for culturing Lentinula edodes. The sugarcane bagasse (SCB), pretreated by liquid hot water (LHW), was h...
Mycorrhizal fungi channel significant amounts of recently fixed plant carbon (C) through the soil, affecting a number of soil processes including the composition and activity of microbial communities and soil organic matter (SOM) mineralization. Some of the mycorrhizal fungi (particularly those establishing ecto-, ericoid and orchid mycorrhizas) can directly mineralize SOM, although often they ...

The cyclic injection of oxygenated water in an aquifer may induce in situ iron removal from groundwater. During injection of aerated water, sorbed ferrous iron is displaced by cations, oxidized in the pore space, and precipitated as ferric iron oxyhydroxide. During pumping, ferrous iron is sorbed from groundwater on the exchange and sorption sites, and the breakthrough of dissolved iron is reta...
short story as an important literary genre in the recent decade is focused by many of young writers and literary critical with searching structure, content , artistic techniques and cognitive phenomenon of these works , we can show quantity of using some parts of storied literature from new literal techniques of the word and also we can show the usage of native, cultural and social foundation...
Well-authenticated information on pineapple plant response to niitrogen constitutes a valuable criterion in commercial fertilizer practices because the amounts and time of their application are determined by the physical appearance of the plants, designated as plant status, as well as by chemical analyses of their tissues. Besides nutrition, physical factors such as light, temperature, and mois...
Nitrogen deficit is one of the most limiting nutrients for plant production. Therefore, identifying diazotrophic indigenous inoculants to promote nitrogen fixation have a great importance in agriculture. In the current study, a number of rhizobacteria isolated from nodules of different legumes cultured in Kerman (IRAN) province. Isolates were screened for their ability to grow on N-free media. ...
Mineral elements are essential nutrients for humans and play important roles in many human physiological and bio-chemical processes. In this study, a comparison between the levels of mineral elements present in the water of public drinking fountains (PDRF) and in bottled water was carried out. The aim of the study is to assess the effectiveness of PDRF as a mineral supplement, compared to the l...
