Research ArticleOpen accessIn the abstractWastewater Treatment Plant Performance Inside Multi-Soil-Layering SystemLamzouri Khaoula, Mahi Mustapha, Masunaga Tsugiyuki et al.Wastewater effluent disposal is a challenge in Moroccan rural area. Wastewater treatment is the only suitable solution to overcome these environmental constraints. Technology such as Multi-Soil-Layering (MSL) system is one of the most appropriate solution for the treatment of wastewater for small communities in rural areas. The MSL system overcomes many of the deficiencies of conventional soil treatment systems such … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 1 Jan 2017 · 8,027 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCost-Effective Wire-Harness Model by Using Polymer Optical FiberMohammad Syuhaimi Ab-Rahman, Farshad Nasimi KhamenehIn the past decade automotive industries faced the exponential increase of in-vehicle electronic devices. The hydraulic systems are replacing with sophisticate electronic systems. Market demands for exploiting new in-vehicle technologies such as multimedia systems, internet access, GPS, Mobile communication, internal private network; engine, body and power train intelligent control and monitoring systems are increasing daily. These new needs make the … …Journal of Computer Science, Vol. 9, Issue 7 · 25 Jun 2013 · 7,021 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGroundwater Flow Systems and Their Response to Climate Change: A Need for a Water-System View ApproachJoel J. Carrillo-Rivera, Antonio CardonaProblem statement: The interest in early hydrogeological studies was the aquifer unit, as it is the physical media that stores and permits groundwater transfers from the recharge zone to the discharge zone, making groundwater available to boreholes for water extraction. Approach: Recently, the aquifer concept has been complemented by the groundwater flow system theory, where groundwater may be defined by … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 7 Apr 2012 · 8,077 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Integration of Network-Based Models for Spill Response and Homeland SecurityDavid E. Amstutz, Rakesh Bahadur, Jonathan M. Pickus et al.The integration of three hydraulic GIS (Geographic Information System) applications is presented which represent the water infrastructures of cities and urban areas and US streams and rivers. The water infrastructures include drinking water distribution systems, wastewater collection systems and source water. The National Research Council[1] states that problems dealing with the collective behavior of networks such as river systems, water … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,729 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSustainable Management of Effluents from Small Piggery Farms in MexicoJ.L. de Victorica-Almeida, M. Galván-García, R. Ayala-RuizIn Mexico, pig farming is the third most important livestock activity due to its contribution to the total meat production. However, it is estimated that around 38% of pig farms dispose their wastewaters without any treatment directly into the nation’s water bodies, which in turn has a severe impact in the environment. One reason for not treating is the high … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 7,365 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAutomatic Measurement of Drilling Parameters to Evaluate the Mechanical Properties of SoilsDaniele Pettinau, Pierpaolo Oreste, Marilena Cardu, Davide GuidarelliAny underground work, carried out either to perform excavations, should be based on detailed knowledge of the geological, hydrogeological and geomechanical conditions of the underlying materials. The continuous automatic diagraphy is a test that consists in the continuous surveying of drilling parameters, with total destruction of the core, which can be used, together with geognostic probing surveys and a detailed … …American Journal of Applied Sciences, Vol. 10, Issue 7 · 17 Jun 2013 · 7,546 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDevelopmental Design of Anaerobic Wetland System for Mining Waste Water TreatmentMuhammad Aqeel Ashraf, Mohd. Jamil Maah, Ismail YusoffProblem statement: Tin mining is one of the oldest industries in Malaysia that have started since 1820s. These mining activities have resulted in about 13,700 hectors of tin tailings throughout the peninsula. These tailings have created numerous environmental problems such as threat to natural reserves due to landscape changes, damage to natural drainage, pollution and destruction of natural habitats. Approach: … …American Journal of Environmental Sciences, Vol. 7, Issue 4 · 10 Oct 2011 · 7,509 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordThermal Hydraulic Analysis of Double Ended Hot Leg Pipeline Break Accident in AP1000 ReactorM.M. Sadeghiazad, F. Choobdar RahimIn the present research, the Loss of Coolant Accident (LOCA), as a postulated accident in nuclear reactors, in its worst condition called large LOCA has been modeled. A specific type of large LOCA in which a totally guillotine break occurs in the hot leg pipe is the Double Ended Hot Leg (DEHL). Once the ‘LOCA’ occurs, the pipe is break … …Energy Research Journal, Vol. 11, Issue 1 · 14 May 2020 · 7,661 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDynamic Models for Rigid Memory MechanismsRelly Victoria Virgil PetrescuThe paper presents a dynamic model that works with variable internal damping, applicable directly to rigid memory mechanisms. If the problem of elasticity is generally solved, the problem of system damping is not clear and well-established. It is usually considered a constant "c" value for the internal damping of the system and sometimes the same value c and for the … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 6 May 2019 · 5,981 accessesView PDF Cite
