Abstract :  Hassan Abad Region is located 180 kilomteres to the northeast of Esfahan along Uremia - Dokhtar Magmatic Belt. Most outcrops in this region belong to Eocene volcanic activity with rhyolite and tuff composition. The rhyolites consist of quartz, plagioclase, alkali feldspar minerals and glass fragments. The tuffs are of crystaline, vitric and ignimbrite typecropping out as interconnected domes along the great fault of Qom - Zofreh with a northern - southern trend. According to geochemical studies and diagrams, the constituent magma of the respective rocks with rholitic composition is classified in calc-alkaline series, and based on spider diagrams of the samples in the studied area, originates from partial melting of custral rocks. Discordant trends of Uremia - Dokhtar Belt and reverse faults as well as regional dykes according to Rieldel model imply that most volcanic and volcanoclastic rocks are subject to simple shear stress in the shear - compressional system (Bargowhar and Marbin - Rangan faults and Kachumesghal - Ganyan fault).

 

Key words : Petrology, Hassan Abad, Uremia - Dokhtar Belt, Rhyiolite, Pyroclastic.

Abstract : The study incorporates determination of physical parameters like pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS) and Total Hardness (TH); cations (Ca2+, Mg2+, Na+ and K+); anions - (HCO3- and Cl ); trace elements (S, P, Zn and Al), hydrocarbons/organic compounds and other particulate matters in the surface and ground waters to study 'environmental pollution' and also to assess the risks posed by an oil refinery at Bina, district Sagar, after 6 years of continued production of oil and other products.

 

Key words : Physical parameters, hydrocarbons, oil refinery, surface water and ground water.

Abstract : The Hybrid Renewable Energy Systems (HRES) are becoming increasingly widespread in power supply in remote areas, due to advances in renewable energy technology and rising oil prices. The hybrid energy system usually uses two or more renewable energy sources, which together increase system efficiency and balance in energy supply (Lee et al., 2016; Rodríguez et al., 2016). In this paper, the Homer software is used to simulate and evaluate the technical and economic aspects of the hybrid systems in order to supply the power of a telecommunication tower in Kaboodarahang, Hamadan. The hybrid system uses turbines, solar panels, diesel generators, and batteries in two on-grid and off-grid forms. The results indicate that the use of hybrid sources is cost-effective in the areas far away from the network. The government can further develop the tendency to use renewable resources, especially wind and solar, for reasons such as availability, less pollution and, more importantly, sustainable economic development in the country by providing financial incentives, including low-interest loans, awareness and supporting involved companies (Clement et al., 2009).

 

Key words : Hybrid System, Homer Software, Solar System, Wind Power Plant, Battery.

Abstract : The performance of soil stabilization using lime to improve the existing in-house (or in-place) soil of the 'Dasna-Hapur Road Project' in Ghaziabad & Hapur districts of Western Uttar Pradesh, India is assessed. This study is conducted on existing soil within Right of Way (ROW) using lime content in various proportions. Geotechnical laboratory tests on modified soil are conducted for soil characterization and mechanical strength. The results show that lime content significantly changed the mechanical performance of natural soil, increasing its mechanical strength and load-carrying capacity and the in-house soil to be used as sub grade. Compaction effort and curing time provided different responses in the California Bearing Ratio (CBR) tests. The best CBR value of 26.3% for the soil-lime mixture with 2% lime is achieved out of existing in-house soil CBR value of 4.38%. It is concluded that instead of replacing of existing soil strata with borrow earth (from 35-60 Km of borrow area) for preparation of sub grade layer, the existing soil can be modified and stabilized to be used as sub grade. This will reduce the environmental load and reduction in terms of cost of transportation of borrowed soil and removal & disposal of existing poor soil.

 

Key words: flexible pavements, soil stabilization, lime stabilization, sub grade.

Abstract : Pesticides are widely used to control unwanted pests such as insects, weeds, fungi and rodents. Increasing use of pesticides to protect crops causes harm to the living being in various ways. Many agricultural pesticide and industrial contents are capable of adversely affecting birds directly and indirectly. Birds are at high risk due to direct or indirect consumption of variety of pesticides. Acephate belongs to a large assembly of organophosphorus pesticides, well-known as inhibitors of acetylcholinesterase activity. The measurement of acetylcholinesterase activity is a better indicator to evaluate the toxicity of organophosphate pesticides. The in vitro effect of OP acephate was studied in liver, heart, kidney, intestine and muscle of chick. Acetylcholinesterase activity was measured by Ellman's method (1961) and 50% inhibitory concentration (IC50) was determined in vitro. The result showed significant variation in IC50 of acephate to AChE in chick organs, which indicates different sensitivity of AChE to acepahte in these organs of chicks.

 

Key words: Acephate, Acetylcholinesterase, IC50,Chick, liver, heart, kidney, muscle, intestine.
