Iran Water management study

Review article of American Journal of Scientific Research and Essays Iran Water management study Hamid kheyrodin Assistant professor in semnan university –Iran Water resource management is a very important issue from several angles such as development of water bodies for future, protection of available water bodies from pollution and over exploitation and to prevent disputes. A paramount issue is water-its availability, quality and management. Water Management Importance. Water Management is important since it helps determine future Irrigation expectations. Water management is the management of water resources under set policies and regulations. Water, once an abundant natural resource, is becoming a more valuable commodity due to droughts and overuse Climate change is expected to intensify the existing risks, particularly in regions where water scarcity is already a concern, as well as create new opportunities in some areas. Efforts to develop adaptation strategies for agricultural water management can benefit from understanding the risks and adaptation strategies proposed to date. This understanding may assist in developing priorities for the adaptation of water resources for irrigation. The adaptation choices consider current technological perspectives and do not project future technological change; we are certain that technological change will shape some choices for adaptation in the coming decades. The greatest scope for action is in improving adaptive capacity and responding to changes in water demands, however the implementation requires revamping current water policy, adequate training to farmers and viable financial instruments.

Review on Denitrification Technologies of Landfill Leachate

Review article of American Journal of Scientific Research and Essays Review on Denitrification Technologies of Landfill Leachate Wang Bo, Ju Jiaqi, Hu Chao, Wei Fuqiang, Wang Ying, Chen Heying College of Ocean Science and Engineering, Shanghai Maritime University, Shanghai 201306, China. The disposal of landfill leachate is a difficult problem in today’s water treatment industry. The landfill leachate contains high concentrations of ammonia nitrogen, which not only increases the difficulty of biological treatment, but also wastes a lot of ammonia energy. This paper reviews the current denitrification methods commonly used in landfill leachate, analyzes their advantages and disadvantages, and proposes the future development direction. Keywords: Landfill Leachate; Nitrogen Removal; Ammonia Nitrogen ...

Research on Thermal Protective Clothing Based on Temperature Distribution

Research article of American Journal of Scientific Research and Essays Research on Thermal Protective Clothing Based on Temperature Distribution Xiaoxi Men1, Guozhu Chen2*, Xiaoxiong Zuo3, Yulong Huang4 1.College of Electrical Engineering & New Energy, China Three Gorges University. 2.College of Hydraulic & Environmental Engineering, China Three Gorges University. 3.College of Science, China Three Gorges University. 4.College of Civil Engineering & Architecture, China Three Gorges University. This paper studies the design of professional clothing for high-temperature operation. Based on the temperature distribution inside the garment and outside the human skin, a mathematical model is established to calculate the temperature distribution. For a three layers fabric material, the heat transfer equation for the fabric layer is established. The heat transfer of the air layer between the fabric and the skin is dominated by radiant heat exchange, effectively interpreting the heat transfer mechanism of the air layer, thereby constructing the energy heat balance equation of the air layer. Combined with the initial conditions and boundary conditions, the spatial and temporal dispersion of the finite explicit difference format is performed.

Fuzzy comprehensive evaluation of fireworks destruction safety based on AHP method

Research article of American Journal of Scientific Research and Essays Fuzzy comprehensive evaluation of fireworks destruction safety based on AHP method Zhou Jun1, Zhang Yiping1, Ren Shaofeng1,2, Zhang Xiuyu2, Wan Sipeng1, Luo Yi1 1School of mining, guizhou university, guiyang 550025, China; 2Guizhou guian xinlian blasting engineering co., LTD., guiyang, guizhou 550004 Aiming at a large number of problems such as complexity, ambiguity and uncertainty existing in the destruction of fireworks, ahp-comprehensive evaluation method was applied to the safety evaluation of the destruction of fireworks. Taking A safe destruction operation in guizhou province as an example, combined with the actual situation on site and expert advice, A two-level structure comprehensive evaluation model of four main factors and 17 sub-factors was established, A judgment matrix was constructed, A weight vector was established, and A fuzzy matrix B was established with membership degree to obtain A comprehensive evaluation matrix D. The evaluation results show that the safety of the destruction of fireworks is good, and the evaluation results are consistent with the actual field effect. The applicability and accuracy of AHP- comprehensive evaluation method in the destruction of fireworks were verified. Keywords: Fireworks; AHP- comprehensive evaluation method; Safety evaluation; The destruction ...
