Case ReportOpen accessIn the abstractUsing Lean Six Sigma to Increase Efficiency of a Grain Receipt Process of a Brazilian Agroindustry CooperativeSeiti Moraes Sakumoto, Daiane Maria De Genaro Chiroli, Ana Caroline DzulinskiDue to the competitiveness of companies to increase market share, they have been more and more interested in topics related to cost reduction, process efficiency, new customers and continuous improvement. Considering this scenario, this study conducted analyses and implemented improvements using the Lean Six Sigma (LSS) methodology in a grain receipt process of a Brazilian agroindustrial cooperative to increase its … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 17 Jun 2019 · 7,612 accessesView PDFCite
Research ArticleOpen accessIn the abstractSemi-Probabilistic Calibration of a Partial Material Safety Factor for Structural Silicone Adhesives - Part II: Verification ConceptMichael A. Kraus, Michael DrassThis paper deals with the application of the semi-probabilistic design concept (level I) to structural silicone sealants where a generally valid verification concept is proposed. The verification concept deals with the classification of silicone adhesive joints into cavitation-insensitive and cavitation-sensitive adhesive joints and at the same time advises which class of material models is necessary for the categorized adhesive joint … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 10 Jan 2020 · 11,269 accessesView PDFCite
Research ArticleOpen accessIn the abstractOligoasthenoteratozoospermia and Necrozoospermia: A Study of Sperm Na+, K+-ATPase α4 and Plasma Membrane Ca2+-ATPase 4 RegulationSilvia W. Lestari, Dessy Noor Miati, AsmarinahThe oligoasthenoteratozoospermia (OAT) and necrozoospermia are the extreme sperm abnormalities in male infertility. These sperm abnormalities may be related to the imbalance of ion transport which mediated by the ion-transporting P-type ATPases, such as Na+, K+-ATPase and Ca2+-ATPase. Until now, there is limited data about the activity of Na+, K+-ATPase and Ca2+-ATPase in sperms in the OAT and necrozoospermia samples. … …OnLine Journal of Biological Sciences, Vol. 18, Issue 3 · 3 Aug 2018 · 11,269 accessesView PDFCite
Research ArticleOpen accessIn the abstractSeismic Fragility Assessment of RC Frame Equipped by Visco-Elastic Dampers Using NLTHA and FNAAli A. Rostam Alilou, Majid PouraminianIn recent years, the issue of lower computational cost and analysis time has been the important factors for the structural analysts. In the meantime, after years of its introduction as an analysis having features of nonlinear analysis, the Fast Nonlinear Analysis (FNA) claims to have a higher performance speed than other nonlinear analyses, but has been less used by the … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 18 Jul 2019 · 8,413 accessesView PDFCite
Research ArticleOpen accessIn the abstractRisks Ratios of Shrinkage Estimators for the Multivariate Normal MeanAbdenour Hamdaoui, Nadia MezouarWe study the estimation of the mean θ of a multivariate Gaussian random variable X∼Np(θ,σ2Ip) in ℜp, σ2 is unknown and estimated by the chi-square variable S2∼σ2χn2. In this work we are interested in studying bounds and limits of risk ratios of shrinkage estimators to the maximum likelihood estimator X, when n and p tend to infinity. We recall that … …Journal of Mathematics and Statistics, Vol. 13, Issue 2 · 3 Apr 2017 · 7,108 accessesView PDFCite
Research ArticleOpen accessIn the abstractImprovement of Bayesian Credible Interval for a Small Binomial Proportion Using Logit TransformationToru Ogura, Takemi YanagimotoA novel credible interval of the binomial proportion is proposed by improving the Highest Posterior Density (HPD) interval using the logit transformation. It is constructed in two steps: first the HPD interval for the logit transformation of the binomial proportion is driven and then the corresponding credible interval of the binomial proportion is calculated by the inverse logit transformation of … …Current Research in Biostatistics, Vol. 8, Issue 1 · 20 Nov 2018 · 7,978 accessesView PDFCite
Review ArticleOpen accessIn the abstractA New Exoplanet Reveals its IdentityNicolae Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuPositioned approximately 70 light years from Earth a sun named by astronomer HD 97658, is nearly bright enough to be seen even with the naked eye. The more interesting part of the problem lies in the fact that this sun, this star, also has an exoplanet HD 97658b, the size of which is approximately double compared to our planet Earth … …Journal of Aircraft and Spacecraft Technology, Vol. 2, Issue 1 · 5 Jun 2018 · 7,495 accessesView PDFCite
Research ArticleOpen accessIn the abstractTesting Composite Valve Covers for Reciprocating Engine ApplicationsPeng Hao Wang, Natalie ZimmermannThe use of composites within the aeronautical field is not limited to airframe applications and includes powerplant components in reciprocating engines. To add to the research body in this area, the presented work aimed to evaluate the performance of novel carbon fiber valve covers installed on an aircraft reciprocating engine. Specifically, the comparative performance between novel composite-based valve covers and … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 3 · 12 Aug 2022 · 5,836 accessesView PDFCite
EditorialOpen accessIn the abstractThe Timeless Contribution of Rootstocks towards Successful Horticultural Farming: From Ancient Times to the Climate Change EraIoannis E. PapadakisGrafting is a horticultural practice by which living vegetative plant organs (root, stem and/or buds) of either the same genotype or, usually, different genotypes belonging to the same species, genus, subfamily and/or family, are tightly connected to each other to form a double-compound plant. In fact, it is a method of asexual (clonal-vegetative) propagation of plants. The basal part of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 16 Dec 2016 · 9,521 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetection of Pesticide Residue in Dams and Well Water in Jazan Area, Saudi ArabiaHasan Y. Al-Hatim, Deifalla Alrajhi, Abdul Jabbar Al-RajabThe application of pesticides indoors and on agricultural lands increased dramatically in recent years in the Jazan area (Saudi Arabia) to control termites and the vectors of diseases, such as Rift Valley Fever (RVF) and malaria. This practice increased the potential risk of pesticide contamination of surface water and groundwater. In this study, samples of 44 wells and 3 dams … …American Journal of Environmental Sciences, Vol. 11, Issue 5 · 3 Nov 2015 · 7,943 accessesView PDFCite
