Research ArticleOpen accessEvery word in the titleIsing Model for Conductive Percolation in Electrically Conductive Adhesives by Considering Random Arrangement of Conducting ParticlesMora, Sahrul Saehana, Euis Sustini et al.Problem statement: Thermodynamically, particles in composites will arrange in a way such that the Helmholtz free energy is minimized. However, even a single structure has the lowest free energy, it should not ignore the probability of other structures having larger energies to occur, although at small chances. Approach: All possible arrangements of particles in the composites, therefore, must be taken … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 30 May 2012 · 7,243 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSpatial Variability of Irrigation Water Percolation Rates and Its Relation to Rice ProductivityW. Aimrun, M.S.M. Amin, A. GholizadehProblem statement: Study on spatial variability of vertical saturated hydraulic conductivity or percolation loss was conducted within a plot of an area of 1.2 ha paddy plot to find out the relationship between percolation rate and rice productivity. A paddy soil condition that permits percolation rate of 10-20 mm irrigation water day-1 was recommended in order to get high yield … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 8,146 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImprovements on Semi Critical Assisted-Solvent Extraction of Biocrude Oil from Spirogyra. sp Macro AlgaeTulio Chavez-Gil, Hany F. Sobhi, Alexis Pacheco-LaracuenteHere, we report on an improved chemical method to extract hydrocarbons (CH) and Fatty Acid Methyl Esters (FAME) from wild green macro algae, which is higher than that carried out with conventional Soxhlet (Sx) and similar to that of Subcritical (SbC) or supercritical fluid (SCE) extraction methods. Crude oil plus residual biomass gave combined calorific values of 49.05 MJ/kg in … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 2 · 18 Apr 2018 · 10,083 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Carboxyl-Functionalized Single Walled Carbon Nanotubes on the Interfacial Barrier Height of Malachite Green Dye Based Organic DeviceSudipta Sen, Nabin Baran ManikIn this study, we have estimated the interfacial barrier height (ɸb) of Indium Tin Oxide (ITO) coated glass/Malachite Green (MG) dye/Aluminium (Al) based organic device and subsequently we have also observed the effect of carboxylfunctionalized SWCNT (COOH-SWCNT) on the ɸb. Presence of COOH-SWCNT reduces the interfacial barrier height as SWCNT acts as filler and provides easy path for charge percolation. … …Physics International, Vol. 10, Issue 1 · 31 Jul 2019 · 12,391 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Mahatma Gandhi National Rural Employment Guarantee Act Activities on Agriculture as Perceived by FarmersS. Thangamalar, S. Kalaivani, S. Palaniswamy, K.R. AshokOut of 66.00% of rural population in India, majority are landless labours depending on the mercy of employment providers for their livelihood. This population is the most vulnerable section to poverty, underemployment, access to development, etc. Therefore the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) has been implemented by the Government of India to improve the living standards of … …Journal of Social Sciences, Vol. 12, Issue 2 · 17 Jun 2016 · 8,167 accessesView PDFCite
Research ArticleOpen accessIn the abstractDENIAL OF SERVICE ATTACK IN DISTRIBUTED WIRELESS NETWORK BY DISTRIBUTED JAMMER NETWORK: A BIRTH-DEATH RANDOM PROCESS ANALYSISR. Dhanasekaran, G. SingaravelLarge number of low power, tiny radio jammers are constituting a Distributed Jammer Network (DJN) is used nowadays to cause a Denial of Service (DoS) attack on a Distributed Wireless Network (DWN). Using NANO technologies, it is possible to build huge number of tiny jammers in millions, if not more. The Denial of Service (DoS) attacks in Distributed Wireless Network … …Journal of Computer Science, Vol. 10, Issue 8 · 7 Mar 2014 · 6,802 accessesView PDFCite
Research ArticleOpen accessIn the abstractPermeability, Strength and Filtration Performance for Uncoated and Titania-Coated Clay Wastewater FiltersMasturi, Silvia, Mahardika Prasetya Aji et al.Problem statement: Wastewater problems continue to be a relevant issue, particularly in urban areas. One promising low-cost material for manufacturing porous ceramics as water filter is clay. Clays can be blended with other materials such as polymers to obtain functional ceramic materials. Approach: Ceramic wastewater filters were fabricated from clay using both sol-gel and simple mixing methods followed by hot-pressing … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 29 Feb 2012 · 8,395 accessesView PDFCite
Research ArticleOpen accessIn the abstractSoil-moisture Retention Characteristics of Earth Materials in the Weathering Profile over a Porphyritic Biotite GraniteJohn Kuna RajProblem statement: Three broad morphological zones and several sub-zones were differentiated within the weathering profile based on variations in earth materials and the degree of preservation of original bedrock minerals, textures and structures. Approach: The topmost Zone I (Grade 6) is some 12 m thick and comprises completely weathered bedrock materials (mainly a stiff, clayey sand) with indistinct relict bedrock … …Current Research in Geoscience, Vol. 1, Issue 1 · 30 Jun 2010 · 9,466 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreliminary Tests Concerning Zero-Valent Iron Efficiency in Inorganic Pollutants RemediationSilvia Fiore, Maria Chiara ZanettiProblem statement: This study was aimed to a preliminary evaluation of the applicability of granular Zero-Valent Iron (ZVI) to the on site remediation of groundwater polluted by inorganic contaminants by means of a Permeable Reactive Barrier (PRB). A particular interest was devoted to groundwater impacted by Acid Mine Drainage (AMD) that was caused by the oxidation of metal sulphide minerals … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 6,789 accessesView PDFCite
