Strategies and management plans of Lopburi province, Thailand need to be developed and enacted in order to remedy some of the problems occurring in human-macaque interface zones. Therefore, this study aimed to investigate the macaque number and behavior, a survey on … …OnLine Journal of Biological Sciences, Vol. 18, Issue 2 · 8 May 2018 · 8,956 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy the Impact of T-helper 1 Cytokine (TNF-α) Polymorphisms on Susceptibility/Resistance to Brucellosis in Makkah RegionAlaa B. Ismael, Adil Mergani, Salama A-H Mostafa, Abdelmoneim M. SalimPolymorphisms in the regulatory regions of cytokine genes may not only increase susceptibility to some infectious diseases but also affect the course and prognosis of the disease. TNF-α is considered an important Th1 cytokines that plays critical roles in control of Brucella infection and in macrophage activation. In this study, we are going to analyze the relationship of two polymorphisms … …American Journal of Infectious Diseases, Vol. 12, Issue 3 · 9 Aug 2016 · 7,119 accessesView PDFCite
Research ArticleOpen accessIn the abstractINVESTIGATION OF THE GROUNDWATER SUITABILITY FOR IRRIGATION PRACTICES IN AN ARID REGION: CASE STUDYAhmed MuradGroundwater is an important source of acceptable water for irrigation in the arid regions and in particular in the United Arab Emirates (UAE). Demand for groundwater is increasing in the UAE due to population growth and significant economic advancement associated with political stability. As agricultural practices are the main land use in Al Hayer area, southeast UAE, majority of extracted … …American Journal of Environmental Sciences, Vol. 10, Issue 1 · 25 Jan 2014 · 7,425 accessesView PDFCite
Research ArticleOpen accessIn the abstractADAPTIVE CLUSTER SAMPLING USING AUXILIARY VARIABLENipaporn ChutimanIn this study we study the estimators of the population mean in adaptive cluster sampling by using the information of the auxiliary variable. The estimators in this study are the classical ratio estimator, the ratio estimator using the population coefficient of variation and the coefficient of kurtosis of the auxiliary variable, the regression estimator and the difference estimator. Simulations showed … …Journal of Mathematics and Statistics, Vol. 9, Issue 3 · 4 Sep 2013 · 9,894 accessesView PDFCite
Research ArticleOpen accessIn the abstractG-2548A Leptin Promoter and Q223R Leptin Receptor Polymorphisms in Obese Mexican SubjectsP. Carrillo-Vazquez Jonathan, Lopez-Alcantar Jeronimo, Chimal-Vega Brenda et al.Leptin interaction with its receptor in the hypothalamus stimulates a specific signaling cascade that results in the synthesis of anorexigenic and orexigenic peptides in order to regulate food intake and energy expenditure. Many polymorphisms in leptin (lep) and leptin receptor (lepr) genes have been associated with body weight. In particular, G-2548A in the lep promoter and Q223R in lepr variants … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 1 · 12 Feb 2013 · 8,641 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Analysis of the Non Linear Epidemic ModelLaid Chahrazed-Rahmani Fouad LazharClassical epidemic models assume that the size of the total population is constant. More recent models consider a population size variable to take into account a longer period with death and disease causing reduced reproductive. The model contains a disease-free equilibrium and one or multiple equilibria are endemic. The stability of a disease-free status equilibrium and the existence of other … …Journal of Mathematics and Statistics, Vol. 8, Issue 2 · 19 Jun 2012 · 7,170 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeasures of Explained Variation and the Base-Rate Problem for Logistic RegressionDinesh Sharma, Dan McGee, B.M. Golam KibriaProblem statement: Logistic regression, perhaps the most frequently used regression model after the General Linear Model (GLM), is extensively used in the field of medical science to analyze prognostic factors in studies of dichotomous outcomes. Unlike the GLM, many different proposals have been made to measure the explained variation in logistic regression analysis. One of the limitations of these measures … …Current Research in Biostatistics, Vol. 2, Issue 1 · 25 Feb 2012 · 8,576 accessesView PDFCite
Research ArticleOpen accessIn the abstractAspergillus Niger Metabolites Efficacies Against the Mosquito Larval (Culex Quinquefasciatus, Anopheles Stephensi and Aedes Aegypti) Population after Column ChromatographyNamita Soni, Soam PrakashProblem statement: Mosquito is a very common vector of several tropical diseases such as malaria, filariasis, dengue and chikungunya. Till todate, many xenobiotics have been used to control mosquito population and protect people from mosquito born diseases but increasing rate of resistance against these xenobiotics is a major concern in the disease control management. In contrast, extensive use of these … …Current Research in Microbiology, Vol. 2, Issue 1 · 21 Dec 2011 · 15,205 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssociation of Anthropometric and Metabolic Variables with Cardiovascular Disease among Urban and Rural OriginBadaruddoza, Kushal Gill, Raman KumarProblem statement: We have examined the prevalence and association of cardiovascular diseases with respect to obesity and metabolic risk factors clustering among urban and rural Punjabi males aged 20-55 years. Obesity has been defined by increased Waist Circumference (WC), Body Mass Index (BMI) and Waist Hip Ratio (WHR). Metabolic traits such as increased total cholesterol, triglycerides and lipoproteins have also … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 20 Aug 2011 · 7,468 accessesView PDFCite
