This work is focused on the effect of heat and mass transfer with unsteady natural convection flow of viscous fluid along with ramped wall temperature under the assumption of the slip wall condition at the boundary. Analytical solutions are obtained by using Laplace transformation to the non-dimensional set of governing equations containing velocity, temperature and concentration. Moreover, the expression for skin-friction is derived by differentiating the analytical solutions of fluid velocity. Numerical tables for Skin-friction, Sherwood number and Nusselt-number are examined. For the physical aspects of the flow, we use various values of involved physical parameters such as Prandtl number(Pr), slip parameter(η), Schmidt number(Sc), buoyancy ratio parameter(N), Sherwood number(Sh), and time(t). Additionally, the general solutions are plotted graphically and a comprehensive theoretical section of numerical discussions is included.

In this paper, synthesis and anticancer activities of morpholine hydrazones scaffold（1-17） thoroughly studied. Small series of morpholine hydrazones synthesized by treating 5-morpholinothiophene-2-carbaldehyde with different aryl hydrazides to form morpholine hydrazones scaffold（1-17）. The in vitro anticancer potential of all these compounds was checked against human cancer cell lines like Hep G2（human hepatocellular liver carcinoma） and MCF-7（human breast adenocarcinoma）. Analogs 13 had similar substantial cytotoxic effects towards Hep G2 with IC_（50） value 6.31±1.03μmmol/L when compared with the standard Doxorubicin（IC_（50）value 6.00±0.80μmmol/L）; while compounds 5,8 and 9 showed potent cytotoxicity against MCF-7 with IC_（50） value 7.08±0.42μmmol/L, 1.26±0.34μmmol/L and11.22±0.22μmmol/L respectively when compared with the standard Tamoxifen（IC_（50）= 11.00±0.40μmol/L）. Molecular docking studies also performed to understand the binding interaction.

In recent years, the Internet has enabled access to widespread remote services in the distributed computing environment; however, integrity of data transmission in the distributed computing platform is hindered by a number of security issues. For instance, the botnet phenomenon is a prominent threat to Internet security, including the threat of malicious codes. The botnet phenomenon supports a wide range of criminal activities, including distributed denial of service(DDoS) attacks, click fraud, phishing, malware distribution, spam emails, and building machines for illegitimate exchange of information/materials. Therefore, it is imperative to design and develop a robust mechanism for improving the botnet detection, analysis, and removal process. Currently, botnet detection techniques have been reviewed in different ways; however, such studies are limited in scope and lack discussions on the latest botnet detection techniques. This paper presents a comprehensive review of the latest state-of-the-art techniques for botnet detection and figures out the trends of previous and current research. It provides a thematic taxonomy for the classification of botnet detection techniques and highlights the implications and critical aspects by qualitatively analyzing such techniques. Related to our comprehensive review, we highlight future directions for improving the schemes that broadly span the entire botnet detection research field and identify the persistent and prominent research challenges that remain open.

A pot experiment was conducted to determine the potential of AM fungi in phytoremediation of heavy metals and its effect on yield of wheat crop. The experiment was conducted in CR Design with four replications during rabi 2012-13. Data showed no increase in grain and shoot yields by AMF inoculation with Zn, Cu, Fe, Mn at different levels but increased root yield, plant height, spike length and hundred grains weight of wheat as compared with uninoculated crop. Post-harvest soil Zn, Cu, Fe and Mn contents of 2, 4.4, 2.8 and 2.9 mg·kg-1, respectively were maximum in uninoculated plants treated with Zn, Cu, Fe, Mn at triple of recommended level. No increases in plant P, N, Zn, Cu, Fe and Mn uptakes were observed by the inoculation of AMF when compared with uninoculated crop. Maximum plant Zn, Cu, Fe and Mn uptakes of 160.5, 206, 1914.6 and 2653 g·ha-1, respectively were recorded in uninoculated plants applied with Zn, Cu, Fe, Mn at triple of recommended levels. Wheat roots infection intensity by AMF increased with higher AMF soil spores density. Results suggest the potential of phytoremediation of contaminated soil to be improved by the inoculation of crops with AMF.
