Research ArticleOpen accessAll words, across the recordLANDSCAPE AND BIOLOGICAL DIVERSITY OF PROTECTED AREAS NETWORK IN PERM KRAIS. A. Buzmakov, P. Yu. SannikovThe problem of creating the systems of specially Protected natural Areas (PA) adequately representing the geographical diversity of different territories has been acute. Creation of the territory nature protection systems always requires comprehensive assessment of the representativeness of the existing PA network. In Perm region the only such research was carried out at the end of the last century. Since … …American Journal of Environmental Sciences, Vol. 10, Issue 5 · 12 Nov 2014 · 7,342 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordBiomimetic Finite Element Analysis Bone Modeling for Customized Hybrid Biological Prostheses DevelopmentAversa Raffaella, Florian Ion T. Petrescu, Relly Victoria V. Petrescu, Apicella AntonioThe human femur shows a high capacity to withstand external stresses and it is due to the mass distribution, morphology, and orthotropic behaviors of trabecular and cortical bone. Faithful modeling of the femur accounting for bone distribution and material orthotropic behavior is presented. The use of biofidel model is aimed to develop an "in silico" tool that could enable the … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 30 Nov 2016 · 8,980 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAssessment of the Maize (Zea mays)-Mucuna (Mucuna deeringianum Bort) AgroecosystemCarlos Ernesto Aguilar-Jimenez, Alfredo Tolon-Becerra, Xavier Lastra-BravoProblem statement: In Selva de Chiapas, Mexico, the traditional farming technique of slash-fell-burn used on hillside fields has caused severe soil deterioration. Consequently, indigenous farmers reacted by developing several agroecological practices that improve the physical, chemical and biological fertility of the soils. Standing out among these techniques is the use of Mucuna (Mucuna deeringianum Bort.) in rotation with maize (Zea … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 2 · 30 Mar 2012 · 7,987 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordPerformance Evaluation of an Oxidation Ditch System with a Disc AeratorAbdel Ghaly, Ashley ThistleProblem statement: The oxidation ditch system has been used to treat various types of wastewaters. Several types of aerators are used to supply the treatment process with oxygen. Among these devices, the disc aerator has certain advantages regarding foam generation over the brush and paddle type rotors, but the main disadvantages of this aerator is the limited oxygenation capacity. The … …American Journal of Applied Sciences, Vol. 8, Issue 7 · 24 Jun 2011 · 8,113 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordExact Simulating of Human Arteries using Lumped Model and Probing Constriction in Femoral and Carotid ArteriesMohammad Reza Mirzaee, Omid Ghasemalizadeh, Bahar FiroozabadiProblem statement: Modeling Human cardiovascular system was always an important issue from long past because by doing such modeling, investigation in cardiovascular system and its abnormities would be simpler. One of the most effective ways to do such modeling is using lumped method (Electrical analogy). Approach: Lumped method was used for simulating a complete model in this approach. A 36-vessel … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,304 accessesView PDFCite
