Large areas of soils have been contaminated by heavy metals, which are deleterious to the existence, reproduction and development of living organisms including plants, animals and microorganisms. The contamination of nature compartments by heavy metals has become a serious environmental problem. Due to the high cost of conventional clean-up technologies, there is an increasing interest in the r...
As the demands for reliable, real-time automation and process control in industrial environments increase, an Industrial Ethernet cabling system quickly becomes the most attractive solution. Cables used in industrial environments must be designed to work in harsh environments of temperature extremes, humidity, and vibration. Many times this can exceed the ranges for information technology equip...
Abstract Nowadays, the water contamination which is due to pharmaceuticals increasing and alarming. The in are very hazardous toxic not only for human life but also environment. One of promising methods removing from contaminated adsorption. Agricultural industrial wastes or by-products can be used as low-cost adsorbents removal. Low-cost provide particular economic environmental advantages. Th...
Food, it's production and preserving has been one of the most important problems in human life. Limitation of production due to climatic, geographic and papulational situations and conservation due to providance and prosecting for solution of one of the most fundamental human needs, has been discussed much. Difference between the lands, temperature, humidity and rainfall on one hand and texture...
Rare asteroidal vesicular basalts have previously been thought to form in surficial lava flows with CO as the vesicle-forming gas. However, vesicular lava flows are unlikely on small, airless bodies such as asteroids. To unravel the origin of these rocks, we analyzed vesicle sizes and abundances for two angrites and two eucrites using high-resolution X-ray computed tomography and conducted nume...
Extensive industrial activities resulted in an increase chromium (Cr) contamination the environment. The toxicity of Cr severely affects plant growth and development. is also recognized as a human carcinogen that enters body via inhalation or by consuming Cr-contaminated food products. Taking consideration enrichment environment its toxic effects, US Environmental Protection Agency for Toxic Su...
