Research ArticleOpen accessEvery word in the titleProfitability Analysis of Small-Scale Beekeeping Firms by Using Life Cycle Costing (LCC) MethodologyAlfio Strano, Teodora Stillitano, Anna Irene De Luca et al.Increasingly, beekeeping sector attracts attention due to its potentialities linked to several aspects: Environmental benefits, commercial value and of promotion of rural development. Indeed, among the small-scale agro-food chains, beekeeping plays a significant role, especially in rural context, where the diversification of farms activities can be provide a relevant integration of income. However, frequently, apicultural activities are characterized by several … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 3 · 27 Jul 2015 · 8,366 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMethods for Computing Missing Item Response in Psychometric Scale ConstructionOhidul Islam SiddiquiTherapeutic potential of a new antidepressant drug is evaluated frequently based on multi-item psychometric scales. The total score of a psychometric scale is calculated based on the responses of multiple-items, in which each item is scored on a likert scale. Missing responses in some of the items are inevitable and hence it is a problem in calculating the total score … …Current Research in Biostatistics, Vol. 5, Issue 1 · 29 May 2015 · 15,648 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSIMULATION OF NANO-SCALE CUTTING WITH MOLECULAR DYNAMICSAngelos P. Markopoulos, Kalliopi-Artemi L. Kalteremidou, Dimitrios E. ManolakosThe simulation of nanometric cutting of copper with diamond cutting tools, with the Molecular Dynamics method is considered. A 2D model of orthogonal nano-scale cutting is presented and the influence of the depth of cut and tool rake angle on chip morphology and cutting forces is investigated. For the analysis, three different depths of cut, namely 10Å, 15Å and 20Å … …Current Research in Nanotechnology, Vol. 5, Issue 2 · 20 Apr 2015 · 7,369 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRAPID DEGRADATION OF AZO DYES USING NANO-SCALE ZERO VALENT IRONNabila Rahman, Zainal Abedin, M. Ali HossainIn the present study, nano-scale Zero Valent Iron (NZVI) was synthesized in ethanol medium by the method of ferric iron reduction using sodium borohydride as a reducing agent under atmospheric conditions. The obtained iron nanoparticles are mainly in zero valent oxidation state and remain without significant oxidation for hours. A systematic characterization of NZVI was performed using XRD, SEM and … …American Journal of Environmental Sciences, Vol. 10, Issue 2 · 8 Apr 2014 · 8,599 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHeat Transfer Enhancement of Small Scale Heat Sinks Using Vibrating Pin FinSuabsakul Gururatana, Xianchang LiHeat sinks are widely adopted in electronics cooling together with different technologies to enhance the cooling process. For the small electronics application, the small scale pin fins heat sinks are extensively used to dissipate heat in electronics devices. Due to the limit of space in the small devices, it is impossible to increase heat transfer area. In order to improve … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 6,867 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUsing Multi-Scale Filtering to Initialize a Background Extraction ModelS. H. Davarpanah, Fatimah Khalid, N. A. Lili et al.Problem statement: Probability-based methods which usually work based on the saved history of each pixel are utilized severally in extracting a background image for moving detection systems. Probability-based methods suffer from a lack of information when the system first begins to work. The model should be initialized using an alternative accurate method. Approach: The use of a nonparametric filtering to … …Journal of Computer Science, Vol. 8, Issue 7 · 24 May 2012 · 7,276 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Innovative Farm Scale Biogas/Composting Facility for a Sustainable Medium Size Dairy FarmA.E. Ghaly, M. Al HattabApproach: The amount of energy related costs as a portion of the total farm operating cost can be as high as 29% and the continuing increase of the real cost of energy related farm input has been one of the major factors impacting the cost of agricultural production. However, agricultural has the potential of replacing some of the purchased energy … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 5 Jan 2012 · 9,320 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleConsensus Decision Making on Scale-Free Buyer NetworksSunantha Sodsee, Maytiyanin Komkhao, Phayung MeesadProblem statement: Due to a behavior of buyers effects to a growth of marketing, then a group of agreement of buyers and buyers’ behavior on eventually placing orders are investigating. Approach: In this study, a discrete-time consensus protocol for a scale-free buyer networks is proposed. Herein, an initial purchase intention of each buyer is defined to be active or non-active … …Journal of Computer Science, Vol. 7, Issue 10 · 8 Aug 2011 · 6,714 accessesView PDFCite
