Research ArticleOpen accessIn the abstractEffects of Dietary Emamectin Benzoate at Recommended and Overdose Levels on the Pathophysiological Responses and Tolerability of Oreochromis niloticus at Fry StageJasmine Singha, Thangapalam Jawahar Abraham, Satyen Kumar Panda, Prasanna Kumar PatilEmamectin Benzoate (EB) has been recommended as a feed additive for the control of fish ectoparasites. This investigation examined the impact of dietary EB on physiological responses, antioxidant defence mechanisms, and histopathological changes in key organs, and on the kinetics of residue deposition and elimination in the muscle of Oreochromis niloticus fry. Fry were administered EB feeds at 50 µg … …American Journal of Pharmacology and Toxicology, Vol. 20, Issue 1 · 1 Jul 2026 · 1,469 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Bivariate Distribution with Generalized Quadratic Hazard Rate MarginalsAbdelfattah MustafaRecently, Sarhan (2009) introduced a new distribution named generalized quadratic hazard rate distribution. In this study, we define a bivariate Generalized Quadratic Hazard Rate Distribution (BGQHRD). The joint cumulative distribution function and joint survival function are derived in compact forms. Several properties of BGQFRD have been discussed. The conditional probability density function, rth moments and joint and marginal moment generating … …Journal of Mathematics and Statistics, Vol. 12, Issue 4 · 3 Nov 2016 · 6,749 accessesView PDFCite
Research ArticleOpen accessIn the abstractCastration and Passive Avoidance Learning Alter the Distribution of N-Methyl D-Aspartate ReceptorSeyed Hassan Mirzaei, Mahnaz Taherianfard, Mina Tadjali, Mahbobeh KohkaloyehIn neurophysiological studies on learning and memory, L-glutamate receptors especially N-Methyl, D-Aspartate glutamate (NMDA) receptors have a major role in different aspect of the learning and memory. Two sites of mammalian brain that show high density of these receptors are CA1 region of hippocampus and Purkinje cell layer of cerebellum. Twenty four Sprague-Dawley rats were used in 4 groups: Control … …Neuroscience International, Vol. 4, Issue 2 · 1 Apr 2014 · 6,773 accessesView PDFCite
Research ArticleOpen accessIn the abstractON THE PRODUCT AND RATIO OF TWO GENERALIZED ORDER STATISTICS FROM THE GENERALIZED BURR TYPE-II DISTRIBUTIONMohamed MaswadahIn this study, the probability density functions of the product and quotient of two generalized order statistics from the generalized Burr Type-XII distribution have been derived, using the Mellin transform and its inverse. Several interesting special cases have also been obtained such as the product and quotient of extreme generalized order statistics and the product and quotient of consecutive generalized … …Journal of Mathematics and Statistics, Vol. 9, Issue 2 · 10 May 2013 · 6,889 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Family of Logarithmic Lifetime DistributionsSaid Hofan AlkarniIn this study a new lifetime class with decreasing failure rate is introduced by compounding truncated logarithmic distribution with any proper continuous lifetime distribution. The properties of the proposed class are discussed, including a formal proof of itsprobability density function, distribution function and explicit algebraic formulae for its reliability and failure rate functions. A simple EM-type algorithm for iteratively computing … …Journal of Mathematics and Statistics, Vol. 8, Issue 4 · 20 Dec 2012 · 7,155 accessesView PDFCite
Research ArticleOpen accessIn the abstractSilkworm Pupae Protect Against Alzheimer’s DiseaseJintanaporn Wattanathorn, Supaporn Muchimapura, Artit Boosel et al.Silkworm (Bombyx mori) pupae have long been used as food and medicine in Asian countries. It is reputed for the treatment of numerous neurological disorders related to oxidative stress including stroke. Therefore, we hypothesized that silkworm pupae could attenuate memory impairment and neurodegeneration in Alzheimer’s disease. In the present study, we determined the effect of silkworm pupae on the neurodegeneration … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 3 · 16 Aug 2012 · 9,697 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Development of Parameter Estimation on Hazard Rate of Trivariate Weibull DistributionIrfan Wahyudi, Purhadi, Irhamah, SutiknoIn this study, the interrelation concepts of trivariate distribution function, trivariate survival function, trivariate probability density function and trivariate hazard rate function of trivariate Weibull distribution are presented. The goal of this contribution is to estimate the trivariate Weibull hazard rate parameters. To reach this goal, we will use an analitical approach in estimating called the Maximum Likelihood Estimation (MLE) … …Current Research in Biostatistics, Vol. 2, Issue 2 · 11 Aug 2012 · 8,923 accessesView PDFCite
Research ArticleOpen accessIn the abstractAphrodisiac Activity of Kaempferia parvifloraJintanaporn Wattanathorn, Prasert Pangphukiew, Supaporn Muchimapura et al.Problem statement: The increasing prevalence of sexual dysfunction and the limitation of therapeutic efficacy nowadays give rise to the requirement of novel therapeutic strategy. Kaempferia parviflora or Krachai-Dun has been long term used in Thai traditional folklore to treat this condition. Unfortunately, no scientific document is available until now. Therefore, this study was undertaken to determine the effect of this … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 2 · 9 Mar 2012 · 10,476 accessesView PDFCite
Research ArticleOpen accessIn the abstractHalf-bounded Numerical Solution of Singular Integral Equations with Cauchy KernelM. Abdulkawi, Z. K. Eshkuvatov, N.M.A. Nik LongProblem statement: In this study, a numerical solution for singular integral equations of the first kind with Cauchy kernel over the finite segment [-1,1] is presented. The numerical solution is bounded at x =1 and unbounded at x = -1. Approach: The numerical solution is derived by approximating the unknown density function using the weighted Chebyshev polynomials of the fourth … …Journal of Mathematics and Statistics, Vol. 7, Issue 1 · 25 Mar 2011 · 7,269 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimation of the Parameters of the Stochastic Differential Equations Black-Scholes Model Share Price of GoldKhaldi Khaled, Meddahi SamiaProblem statement: The estimation of the parameters is one of main problems of the dynamic models in many scientific fields and particularly in economics and finance. In this study, we examine the techniques of estimation of the parameters of the Black-Scholes model. These techniques are based on the function of probability. Approach: The two estimations are based on the likelihood … …Journal of Mathematics and Statistics, Vol. 6, Issue 4 · 24 Dec 2010 · 7,711 accessesView PDFCite
