Mixed convection stagnation-point flow on vertical stretching sheet with external magnetic field

引用

Applied Mathematics and Mechanics(English Edition) 2014年第2期35卷 155-166页

作者： F.M.ali R.NAZAR N.M.ARIFIN I.POP Department of Mathematics & Institute for Mathematical Research Universiti Putra Malaysia UPM School of Mathematical Sciences Faculty of Science & TechnologyUniversitiKebangsaan Malaysia UKM Department of Mathematics Babes-Bolyai University

The problem of steady laminar magnetohydrodynamic （MHD） mixed con- vection stagnation-point flow of an incompressible viscous fluid over a vertical stretch- ing sheet is studied. The effect of an externally magnetic field is taken into account. The transformed boundary layer equations are solved numerically by using an implicit finite-difference scheme. Numerical results are obtained for various values of the mixed convection parameter, Hartmann number, and Prandtl number. The effects of an exter- nally magnetic field on the skin friction coefficient, local Nusselt number, velocity, and temperature profiles for both A 〉 1 and A ~ 1, where A is the velocity ratio parameter, are presented graphically and discussed in detail. Both assisting and opposing flows are considered, and it is found that dual solutions exist for the opposing flow.

Pathogenicity of bacterium, Xenorhabdus nematophila isolated from entomopathogenic nematode (Steinernema carpocapsae) and its secretion against Galleria mellonella larvae

引用

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2005年第6期6卷 457-463页

作者： MAHAR ali Nawaz MUNIR Muhammad ELAWAD Sami GOWEN Simon Richard HAGUE Nigel Graham Meckenzi Department of Agriculture University of Reading Reading RG6 6AT UKSchool of Plant Sciences University of Reading Reading RG6 6AS UKDepartment of Agriculture University of Reading Reading RG6 6AT UKDepartment of Agriculture University of Reading Reading RG6 6AT UKDepartment of Agriculture University of Reading Reading RG6 6AT UK

The entomopathogenic bacterium, Xenorhabdus nematophila was isolated from the hemolymph of Galleria mel- lonella infected with Steinernema carpocapsae. The bacterial cells and its metabolic secretions have been found lethal to the Galleria larvae. Toxic secretion in broth caused 95% mortality within 4 d of application whereas the bacterial cells caused 93% mortality after 6 d. When filter and sand substrates were compared, the later one was observed as appropriate. Similarly, bacterial cells and secretion in broth were more effective at 14% moisture and 25 °C temperature treatments. Maximum insect mortality (100%) was observed when bacterial concentration of 4×106 cells/ml was used. Similarly, maximum bacterial cells in broth (95%) were penetrated into the insect body within 2 h of their application. However, when stored bacterial toxic secretion was applied to the insects its efficacy declined. On the other hand, when the same toxic secretion was dried and then dissolved either in broth or water was proved to be effective. The present study showed that the bacterium, X. nematophila or its toxic secretion can be used as an important component of integrated pest management against Galleria.

Postoperative day one serum alanine aminotransferase does not predict patient morbidity and mortality after elective liver resection in non-cirrhotic patients

ABSTRACT： Serum aminotransferases have been used as surrogate markers for liver ischemia-reperfusion injury that follows liver surgery. Some studies have suggested that rises in serum alanine aminotransferase （ALT） correlate with patient outcome after liver resection. We assessed whether postoperative day 1 （POD 1） ALT could be used to predict patient morbidity and mortality following liver resection. We reviewed our prospectively held database and included consecutive adult patients undergoing elective liver resection in our institution between January 2013 and December 2014. Primary outcome assessed was correlation of POD 1 ALT with patient＇s morbidity and mortality. We also assessed whether concurrent radiofrequency ablation, neoadjuvant chemotherapy and use of the Pringle maneuver significantly affected the level of POD 1 ALT. A total of 110 liver resections were included in the study. The overall in-hospital patient morbidity and mortality were 31.8% and 0.9%, respectively. The median level of POD 1 ALT was 275 IU/L. No correlation was found between POD 1 serum ALT levels and patient morbidity after elective liver resection, whilst correlation with mortality was not possible because ofthe low number of mortalities. Patients undergoing concurrent radiofrequency ablation were noted to have an increased level of POD 1 serum ALT but not those given neoadjuvant chemotherapy and those in whom the Pringle maneuver was used. Our study demonstrates POD 1 serum ALT does not correlate with patient morbidity after elective liver resection.

In the present work, carbon nano/microparticles obtained by controlled pyrolysis of peanut （PS） and hazelnut （HS） shells are presented. These materials were characterized by Raman spectroscopy and field emissionscanning electron microscopy （FE-SEM）. When added to cement paste, up to 1 wt%, these materials led to an increase of the cement matrix flexural strength and of toughness. Moreover, with respect to plain cement, the total increase in electromagnetic radiation shielding effect when adding 0.5 wt% of PS or HS in cement composites is much higher in comparison to the ones reported in the literature for CNTs used in the same content.

Transcription activator-like effectors （TALEs） from Xanthomonas sp. have been used as customizable DNA- binding modules for genome-engineering applications, Ralstonia solanacearum TALE-like proteins （RTLs） exhibit similar structural features to TALEs, including a central DNA-binding domain composed of 35 amino acid-long repeats. Here, we characterize the RTLs and show that they localize in the plant cell nucleus, mediate DNA binding, and might function as transcriptional activators. RTLs have a unique DNA-binding architecture and are enriched in repeat variable di-residues （RVDs）, which determine repeat DNA-binding specificities. We determined the DNA-binding specificities for the RVD sequences ND, HN, NP, and NT. The RVD ND mediates highly specific interactions with C nucleotide, HN interacts spe- cifically with A and G nucleotides, and NP binds to C, A, and G nucleotides. Moreover, we developed a highly efficient repeat assembly approach for engineering RTL effectors. Taken together, our data demonstrate that RTLs are unique DNA-targeting modules that are excellent alternatives to be tailored to bind to user-selected DNA sequences for targeted genomic and epigenomic modifications. These findings will facilitate research concerning RTL molecular biology and RTL roles in the pathogenicity of Ralstonia spp.
