abstract: advertisements are the most accessible type of authentic materials, and this is one reason why they are used more and more in english teaching classes. for this cause, studies in the field of advertisements are very widespread nowadays. for pun is one aspect which makes advertisements more interesting, it is used more than before in advertisements. use of puns makes an advertisement m...
abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...
Knowledge of the distribution of heavy metal concentrations in different components of soil particles is significant to assess the risk of heavy metals. The objective of this study was to evaluate some pollution indices and spatial variations in their estimation in different components of soil particle size fractions (<2000 and> 63 μm) in the Baghan watershed in the southeast of Bushehr provinc...
Background: Contamination of the environment due to heavy metals is a major concern to human life and the environment. This study was conducted to investigate and quantify the copper and zinc concentrations in industrial estates soil in Arak, Iran. Methods: Four industrial estates were considered for the experimental design, including Arak 1, Arak 2, Arak 3, and Ghotbe Sanaati. For prelimin...
heavy metal contamination in the environment could cause harmful effects both to human health and aquatic life. numerous remediation methods had been developed to encounter with the contamination problem prior to degrade, decrease and to purify the contaminated water at minimal concentration as low as possible. therefore, in current study, commercialized chicken eggshells and hybrid akar putra ...
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
1 www.ijeas.org Abstract— Soil contamination from industrial effluents and mining activities is a widespread concern all over the world. Generally soil act as the buffer zone between atmosphere and underground water, thus soil contamination creates a serious threat to soil and to the surrounding biosphere. This research program is aimed to make an in-depth investigation about the remediation ...
Although Iran's Ghaen Plain provides saffron to much of the world, no regional groundwater quality (GQ) assessment has yet been undertaken. Given the region's potential for saltwater intrusion and heavy metal contamination, it is important to assess the GQ and determine its main probable source of pollution (MPSP). Such knowledge would allow for informed mitigation or elimination of the potenti...
gabrik in the east of hormozgan province is mangrove habitat and one of the important mangrove protected area. this area is located in oman coasts. this zone because of building jagin dam on gabrick river and existence of sand barrier and exposure of pollution, it is possible to destroy or to be important threats of this planet. base on importance of this sea inhabitation some of sedimentology ...
Background: Non-biodegradation in nature and the creation of adverse health effects in humans is important features of heavy metals. The main purpose of this study was to determine the carcinogenic and non-carcinogenic risks of heavy metals As, Cd, Cu, Cr, Pb, Ni, V, and Zn in the soils of industrial areas of Mahshahr port for adults and children. Methods: To study the environmental effects of ...
