1柴油降解新菌株的筛选及降解条件的研究显示文摘从喀麦隆未被柴油污染的土壤样品中分离获得一株柴油降解酵母KML。经形态和生理生化特征鉴定及5.8SrDNA-ITS序列分析,该酵母菌株属于解脂耶罗维亚酵母(Yarrowia lipolytica)。利用紫外分光光度法测定了该菌对柴油的降解率。通过单因素试验得到该菌株降解柴油的最适降解条件为:温度30℃,pH9,酵母膏1g/L,鼠李糖脂浓度10g/L。GC-MS分析可知,该菌种对柴油有很好的降解能力。Marie Thérèse Bidja Abena 谢观莲 钟卫鸿 2013黑龙江科学2013,4,2:2

4Quasi-likelihood techniques in a logistic regression equation for identifying Simulium damnosum s.l.larval habitats intra-cluster covariates in Togo显示文摘The standard methods for regression analyses of clustered riverine larval habitat data of Simulium damnosum s.l.a major black-fly vector of onchoceriasis,postulate models relating observational ecological-sampled parameter estimators to prolific habitats without accounting for residual intra-cluster error correlation effects.Generally,this correlation comes from two sources:(1)the design of the random effects and their assumed covariance from the multiple levels within the regression model and(2)the correlation structure of the residuals.Unfortunately,inconspicuous errors in residual intracluster correlation estimates can overstate precision in forecasted S.damnosum s.l.riverine larval habitat explanatory attributes regardless how they are treated(e.g.independent,autoregressive,Toeplitz,etc.).In this research,the geographical locations for multiple riverine-based S.damnosum s.l.larval ecosystem habitats sampled from two preestablished epidemiological sites in Togo were identified and recorded from July 2009 to June 2010.Initially,the data were aggregated into PROC GENMOD.An agglomerative hierarchical residual cluster-based analysis was then performed.The sampled clustered study site data was then analyzed for statistical correlations using monthly biting rates(MBR).Euclidean distance measurements and terrain-related geomorphological statistics were then generated in ArcGIS.A digital overlay was then performed also in ArcGIS using the georeferenced ground coordinates of high and low density clusters stratified by annual biting rates(ABR).The data was overlain onto multitemporal sub-meter pixel resolution satellite data(i.e.QuickBird 0.61m wavbands).Orthogonal spatial filter eigenvectors were then generated in SAS/Geographic Information Systems(GIS).Univariate and nonlinear regression-based models(i.e.logistic,Poisson,and negative binomial)were also employed to determine probability distributions and to identify statistically significant parameter estimators from the sampled data.Thereafter,Durbin–Watson statistics were used to test the null hypothesis that the regression residuals were not autocorrelated against the alternative that the residuals followed an autoregressive process in AUTOREG.Bayesian uncertainty matrices were also constructed employing normal priors for each of the sampled estimators in PROC MCMC.The residuals revealed both spatially structured and unstructured error effects in the high and low ABR-stratified clusters.The analyses also revealed that the estimators,levels of turbidity,and presence of rocks were statistically significant for the high-ABR-stratified clusters,while the estimators distance between habitats and floating vegetation were important for the low-ABR-stratified cluster.Varying and constant coefficient regression models,ABRstratified GIS-generated clusters,sub-meter resolution satellite imagery,a robust residual intra-cluster diagnostic test,MBR-based histograms,eigendecomposition spatial filter algorithms,and Bayesian matrices can enable accurate autoregressive estimation of latent uncertainity affects and other residual error probabilities(i.e.heteroskedasticity)for testing correlations between georeferenced S.damnosum s.l.riverine larval habitat estimators.The asymptotic distribution of the resulting residual adjusted intra-cluster predictor error autocovariate coefficients can thereafter be established while estimates of the asymptotic variance can lead to the construction of approximate confidence intervals for accurately targeting productive S.damnosum s.l.habitats based on spatiotemporal field-sampled count data.Benjamin G.JACOB Robert J.NOVAK Laurent TOE Moussa S.SANFO Abena N.AFRIYIE Mohammed A.IBRAHIM Daniel A.GRIFFITH Thomas R.UNNASCH 2012Geo-Spatial Information Science2012,15,2:1

8The Ebola virus:a review of progress and development in research显示文摘The Ebola virus was identified in the year 1976 and has caused periodic outbreaks in West African countries.The disease has a case fatality rate up to 90%.Ebola has been classified as a biosafety level four pathogen and there is no currently approved vaccine or treatment for the virus.However,remarkable progress has been demonstrated by researchers in understanding the pathogenicity of the Ebola virus.Several animal models have been cultivated to develop diagnostics,vaccines and therapeutic drugs.Yitades Gebre Teshome Gebre Abena Peters 2014Asian Pacific Journal of Tropical Biomedicine2014,4,12:1
