Research ArticleOpen accessIn the keywordsImpact of Microfinance on the Efficiency of Maize Producers in NigeriaMuhammad Auwal Ahmed, Zainalabidin Mohamed, Abdullahi Iliyasu, Golnaz RezaiThe study applies descriptive analysis, Slacks-Based Measure (SBM) of efficiency model and fractional regression model to data collected in 2016 using cross-sectional survey of maize producers in Nigeria. The purpose was to determine the impact of microfinance on the technical efficiency of maize producers and evaluates factors that influence inefficiency among credit beneficiaries and non-credit beneficiaries. Results show that the … …American Journal of Applied Sciences, Vol. 14, Issue 5 · 30 May 2017 · 7,673 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSome Contributions to the Theory of Abstract Degenerate Volterra Integro-Differential EquationsMarko KostićIn this study, we contribute to the existing theory of abstract degenerate Volterra integro-differential equations in sequentially complete locally convex spaces. We investigate a class of abstract degenerate Volterra inclusions by using the multivalued linear operator approach, as well as a class of abstract degenerate multi-term fractional differential equations with Caputo derivatives by using the pure Laplace transform techniques. …Journal of Mathematics and Statistics, Vol. 12, Issue 2 · 17 Jun 2016 · 7,411 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRobust Diagnosis of a DC Motor by Bond Graph ApproachAbderrahmène Sallami, Nadia Zanzouri, Mekki KsouriIn this article, a Bond Graph (BG) approach is used for modeling, simulation and robust diagnosis of a DC Motor. The design and calculation of an observer is achieved by using graphical methods taking advantage of the structural properties of bond graph model. Simulation results are used to show the dynamic behavior of the system variables and assessing the performance … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 17 Jun 2016 · 8,005 accessesView PDFCite
Research ArticleOpen accessIn the keywordsUtilization of Sewage Sludge in Agricultural Soil as Fertilizer in the Republic of Benin (West Africa): What are the Risks of Heavy Metals Contamination and Spreading?Fidèle Suanon, Lyde A.S. Tomètin, Biaou Dimon et al.Biosolids are the treated organic residuals, also known as sewage sludge, which are generated from domestic wastewater treatment plants. It is an organic matter and nutrients [phosphorous (P) and nitrogen (N)]-rich material. Due to these properties, it is has been reported to be a suitable fertilizer or soil amendment which can valuably replace synthesized NPK. Unfortunately, this matter is heavily … …American Journal of Environmental Sciences, Vol. 12, Issue 1 · 6 Jan 2016 · 14,506 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTHE GROUP COMPOSITION OF METAL COMPOUNDS IN SOIL AS AN INDEX OF SOIL ECOLOGICAL STATESaglara Sergeevna Mandzhieva, Tatiana Mikhailovna Minkina, Svetlana Nikolaevna Sushkova et al.A system of indices for assessing the soil ecological state as based upon the group composition of heavy metal compounds in soils is proposed. The group composition of heavy metal were determined using combined fractionation including sequential and parallel extractions (1 N NH4Ac, pH 8; 1% EDTA in NH4Ac and 1 N HCl). It was shown that strongly bound compounds … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 7 Dec 2013 · 7,595 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIntegrated Supercritical Fluid Extraction and BioprocessingOwen Catchpole, Stephen Tallon, Peter Dyer et al.Supercritical fluids are increasingly being used and promoted at a laboratory and pilot scale to produce high value, natural bioactives from biologically based raw materials. Supercritical CO2 is overwhelmingly the solvent of choice for these operations, but is largely limited to the processing of dry raw materials and the extraction of low polarity, low molecular weight compounds. The use of … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 4 · 25 Dec 2012 · 9,498 accessesView PDFCite
Research ArticleOpen accessIn the keywordsExtraction, Purification and Characterization of Fish Chymotrypsin: A ReviewLiang Zhou, Suzanne M. Budge, Abdel E. Ghaly et al.Problem statement: Solid fish waste is generated from the unwanted parts of fish including heads, tails, fins, frames, offal (guts, kidney and liver) and skin. It accounts for up to 80% of material from production of surimi, 66% from production of fillet and 27% from production of headed and gutted fish. Currently, fish wastes are disposed off in land-based waste … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 3 · 22 Sep 2011 · 10,591 accessesView PDFCite
Research ArticleOpen accessIn the keywordsElectromagnetic Interference Mitigation for Inverter fed AC DrivesC. Karthikeyan, K. DuraiswamyProblem statement: In switched mode PWM inverter EMI noise occurs during high (dv/dt) transient period. This EMI noise is mitigated using Active Common mode EMI filter in front of the source. Approach: This study proposes a new active common mode Electromagnetic Interference (EMI) filter for switched mode PWM Inverter applications. The proposed filter is based on current sensing and compensation … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 12 Sep 2011 · 7,313 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOn Certain Classes of Multivalent Analytic FunctionsRabha W. Ibrahim, Maslina DarusProblem statement: By means of the Hadamard product (or convolution), new class of function of power order was formed. This class was motivated by many authors namely MacGregor, Umezawa, Darus and Ibrahim and many others. The class indeed extended in the form of integral operator due to the work of Bernardi, Libera and Livingston. Approach: A new class of multivalent … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 7,441 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Determination of Optimal Crop Pattern with Aim of Reduction in Hazards of EnvironmentalMahmoud Daneshvar Kakhki, Nasser Sahnoushi, F. Salehi Reza AbadiProblem statement: The purpose of the study was to find the optimal cropping pattern, in Taybad, which maximizes the net return per water cubic meter and per fertilizer kilogram. Approach: A linear programming model and a fuzzy multi-objective fractional programming model were applied and then these models were compared. Results: Result of study showed ratio of net return into consumption … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 8,285 accessesView PDFCite
