Research ArticleOpen accessIn the abstractEvaluating the Maintenance Performance of the Semiconductor Factories Based on the Analytical Hierarchy Process and Grey Relational AnalysisFei-Long Chen, Yun-Chin ChenProblem statement: Maintenance is an important factor in semiconductor factories, not only because of costs and the need for the uninterrupted operation of semiconductor equipment, but also the time and expense required for maintenance. If maintenance procedures are not performed properly, the equipment will have low efficiency or break down, production capacity will decrease and the company will incur extra … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 7,308 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Dietary Fat Type and Amount on Growth Performance and Serum Cholesterol in RabbitsA. Alhaidary, H. E. Mohamed, A.C. BeynenProblem statement: Literature data on the effect of dietary fat on growth performance in rabbits are inconclusive. For commercial rabbit production it is relevant to know to what extent dietary fat level and type can be manipulated. In the present study serum cholesterol was also analyzed because its relation to the amount and type of dietary fat was not known … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 7,476 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Dietary Herbal Antioxidants Supplemented on Feedlot Growth Performance and Carcass Composition of Male GoatsMorteza Karami, Abd Razak Alimon, Yong Meng Goh et al.Problem statement: In goats production, chevon, meat quality and shelf life are very important, dietary herbs and synthetic antioxidants as dietary supplementation, may be can improve growth performance and carcass characteristics of goats. Approach: Thirty-two male (mean live weight 13.0 kg and 8 months old) were assigned to four dietary treatments, namely, basal diet (control, CN) and basal diet supplemented … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 9,732 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of a Comprehensive Computer Program for Predicting Farm EnergyS.A. Al-Hamed, S.A. Al-Suhaibani, F.S. Mohammad, M.F.I. WahbyProblem statement: The agricultural industry is a major user of energy. Energy is used directly for operating agricultural machinery and equipment on the farm and indirectly in the manufacturing of fertilizers and pesticides and processing of agricultural products off the farm. In order to reduce the cost of agricultural production, energy uses on the farm must be identified and optimized … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 8,061 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Surface Treatment on Fatigue Life of Cylinder Block for Linear Engine using Frequency Response ApproachM. M. Rahman, A. K. Ariffin, S. Abdullah et al.Objectives: This study was focused on the finite element techniques to investigate the effect of surface treatment on the fatigue life of the vibrating cylinder block for new two-stroke free piston engine using random loading conditions. Motivation: An understanding of the effects related to the random loading is necessary to improve the ability of designers to accurately predict the fatigue … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 8,139 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermodynamic Investigation of Two-Stage Absorption Refrigeration System Connected by a CompressorL. Kairouani, E. Nehdi, R. B. IffaThe present work is to analyze a two-stage cycle based on the ammonia-water absorption system, with intermediate compression. The two generators of the system are heated by geothermal energy at low temperature. The study shows that this system makes it possible at lower generator temperature, under the limits permitted by the systems suggested up to now. For Tg = 335 … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 6,737 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordImproved Compost Production from Fruit and Vegetable Market Waste: A Case Study in Bagua, Amazonas (Peru)Juan Eduardo Suarez Rivadeneira, Freddy A. Manayay, Wilfredo Ruiz Camacho, Juan Francisco Robles RuizInadequate management of organic solid waste in municipal markets represents a critical environmental challenge in tropical developing regions, where high humidity (>80%) and elevated temperatures (>25°C) accelerate decomposition, generating leachate and greenhouse gas emissions. In Peru, over 50% of municipal waste is organic, yet less than 20% is valorised through composting, highlighting a substantial technological gap. This study evaluated an … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 11 Aug 2026 · 1,262 accessesView PDFCite
