Research ArticleOpen accessPhrase in the titleThe Efficiency Measurement of Parallel Production Systems: A Non-radial Data Envelopment Analysis ModelAli Ashrafi, Azmi Bin Jaafar, Mohd Rizam Abu Bakar, Lai Soon LeeProblem statement: Data Envelopment Analysis (DEA) is a non-parametric technique for measuring the relative efficiency of a set of production systems or Decision Making Units (DMU) that have multiple inputs and outputs. Sometimes, DMUs have a parallel structure, in which systems composed of parallel units work individually; the sum of their own inputs/outputs is the input/output of the system. For … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 9,253 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleAn Optimal Control Approach to Inventory-Production Systems with Weibull Distributed DeteriorationMd. Azizul Baten, Anton Abdulbasah KamilProblem statement: We studied the inventory-production system with two-parameter Weibull distributed deterioration items. Approach: The inventory model was developed as linear optimal control problem and by the Pontryagin maximum principle, the optimal control problem was solved analytically to obtain the optimal solution of the problem. Results: It was then illustrated with the help of an example. By the principle of … …Journal of Mathematics and Statistics, Vol. 5, Issue 3 · 30 Sep 2009 · 7,549 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleLong-term Effect of Conventional and No-Tillage Production Systems on Nitrous Oxide Fluxes from Corn (Zea mays L.) Field in Southwestern QuebecAbdirashid Elmi, Bano Mehdi, Chandra Madramootoo et al.Problem statement: There is a growing trend in the adoption of conservation tillage as an alternative to conventional tillage farming system. Implications of this agricultural management shift with respect to nitrous oxide (N2O) emission, which has been a topic of intense research for the past few decades, is not yet completely understood. Approach: This study was conducted on a 2.4 … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,016 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFungal Culture Systems for Production of Antioxidant Phenolics Using Pecan Nut Shells as Sole Carbon SourceMiguel A. Medina, Ruth E. Belmares, Antonio Aguilera-Carbo et al.Problem statement: Many agro-industrial wastes have little or none utilization, when these materials could be a very rich source of several value-added compounds, such as: the pecan nut shells, which contain Antioxidant Phenolic (AP) molecules like tannins. Approach: In this study, a bioprocess for the liberation of AP from Pecan Nut Shells (PNS) was described. A chemical characterization of raw … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,042 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGrowth Performance and Blood Profiles of Indigenous Venda Chickens Under Intensive and Semi-Intensive Rearing SystemsBoasiako Oris Antwi, Ifeanyichukwu Princewill Ogbuewu, Christian Anayo MbajiorguA 91-day trial examined the impact of two production systems on crop content, growth performance, hematology, and blood chemistry of indigenous Venda chickens. One-day-old Venda chickens (n = 100) were randomly assigned to two treatments (T1 and T2) and replicated five times with 10 birds per replication. Venda chickens in each group were placed in five replicate pens, each having … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 1 · 12 Apr 2026 · 1,424 accessesView PDFCite

Research ArticleOpen accessIn the abstractBioethanol Production from Graminoid Weeds in Bayero University Kano: A Potential Feedstock for Future Sustainable Aviation Fuel ApplicationsAdam Salihu Kila, Sa’idu Hassan Musa, Umar Aliyu Ahmed et al.This study evaluates the potential of selected graminoid weeds from Bayero University, Kano (BUK), Nigeria, as feedstock for bioethanol production. Ten (10) abundant weed species, including Cenchrus species, Cynodon dactylon, and Setaria barbata, were subjected to physicochemical pretreatment (ultrasonication, hydrothermal treatment, and enzymatic hydrolysis) followed by fermentation using Bacillus subtilis, Saccharomyces cerevisiae, and their co-culture. Pretreatment significantly enhanced reducing sugar … …Energy Research Journal, Vol. 15, Issue 1 · 15 Jul 2026 · 1,170 accessesView PDFCite
Review ArticleOpen accessIn the abstractHydroponic Fodder in Broiler Nutrition: Effects on Economics of Production, Environmental Impacts, Productive Indices, and Health StatusChristian Anayo Mbajiorgu, Ifeanyichukwu Princewill Ogbuewu, Monnye MabelebeleThe projected global population of 9.7 billion by 2050 will escalate the demand for animal protein, intensifying food insecurity. Broilers, being highly efficient in converting grains into protein-rich food, are crucial in meeting the ever-increasing demand for animal proteins. However, broiler production, especially in developing countries, is constrained by low quality and unavailability of conventional feed grains utilized in poultry … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 1 · 14 Apr 2026 · 1,694 accessesView PDFCite
