Strain Pattern Analysis of Mylonites From Sitampundi-Kanjamalai Shear Zone, Thiruchengode, South India

This study aims to investigate the petrography and strain pattern of mylonites from parts of N-S trending Sitampundi-Kanjamalai Shear Zone (SKSZ) around Thiruchengode. The petrographic study indicates the presence of recrystallized quartz, K-feldspar, plagioclase, biotite and some hornblende. The kinematic analysis of Mylonites was done with the help of shear sense indicators such as recrystallized type quartz (quartz ribbon) around the cluster of feldspar, S-C fabric shows dextral shear sense and some sinisterly shear sense in some parts of SASZ which can be considered as a product of partitioning of both strain and vorticity between domains. These all indicates the simple shear extension along E-W direction and the mylonitic foliation shows the pure shear compression along N-S direction. Further the study of bulk strain analysis by Flinn plot method using L and T section of mylonite shows k<1 which lies in the field of flattening zone of finite strain. The kinematic vorticity number is calculated by Rxz/β method which gives the value of 0.36 indicating the general shear. The rigid grain graph shows that the pure shear component is more ­­­­dominant than the simple shear component. The analysis leads to the conclusion that the mylonite has experienced a high temperature shearing of above 700°cat deep crustal level

Pilot scale microbial production and optimization of Serratia peptidase from Serratia marcescens

Serratia peptidase is active proteolytic enzyme which has the potential of cleaving peptide bond.  Present investigation deals about the Microbial production of serratia peptidase using Serratia marcescens in small scale fermentor. Batch fermentor has been run continuously throughout the night to analyze the production of protein as well as kinetics. Culture broth was maintained at 150rpm for 72 hrs. Protein sample was isolated by centrifuging at 3000rpm for 10mints. The result revealed that Serratia marcescens showed the enormous production of protein in fed batch fermentor compared to the small scale level.  Different substrates were been used for the production of enzyme. Among all cysteine showed the better activity as 2 units/ml of enzyme. Enzymatic assay of Serratia peptidase was done at different time interval of crude broth. Enzyme activity showed that maximum at 40ºC for 72hrs. It was observed that 0.65 units/ml of enzyme. Fed batch pilot scale production of Serratia peptidase was done at 0.5%cystein and 700rpm for 48hrs of run time.Â

Green Campus Audit Procedures and Implementation to Educational Institutions and Industries

Nature provides a free lunch, but only if we control our appetites. As we are in the twenty-first century, modernization and industrialization are the two important outputs that have made human life more luxurious and comfortable. Simultaneously, they are responsible for several uses of exploitation of forests, natural resources, and wildlife, polluting the scarce, producing massive solid waste and sacred water resources, and finally making our planet Earth ugly and inhospitable. Today, people are getting more familiar with global issues like global warming, the greenhouse effect, ozone depletion, climate change, etc. Now, it is considered a final call by Mother Earth to walk on the path of sustainable development. The time has come to wake up, unite and combat together for a sustainable environment. The present study focuses on the concept of green audit and its importance with respect to the conservation of nature for future generations. Every organization should have its own green campus and environment policy with respect to nature conservation and environmental protection and should maintain a sizable amount of green cover area after building construction along with natural and planted vegetation. A maximum number of more oxygen-producing and carbon-di-oxide-absorbing plants should be maintained to provide a pure atmosphere to the stakeholders. The installation of a rainwater harvesting system, percolation, ponds, check dam, and drip irrigation system to conserve rainwater and groundwater should be noteworthy on the campus

DDoS defense by offense

This article presents the design, implementation, analysis, and experimental evaluation of speak-up, a defense against application-level distributed denial-of-service (DDoS), in which attackers cripple a server by sending legitimate-looking requests that consume computational resources (e.g., CPU cycles, disk). With speak-up, a victimized server encourages all clients, resources permitting, to automatically send higher volumes of traffic. We suppose that attackers are already using most of their upload bandwidth so cannot react to the encouragement. Good clients, however, have spare upload bandwidth so can react to the encouragement with drastically higher volumes of traffic. The intended outcome of this traffic inflation is that the good clients crowd out the bad ones, thereby capturing a much larger fraction of the server's resources than before. We experiment under various conditions and find that speak-up causes the server to spend resources on a group of clients in rough proportion to their aggregate upload bandwidths, which is the intended result.National Science Foundation (U.S.) (NSF grant CNS-0225660)National Science Foundation (U.S.) (NSF grant CNS-0520241)United States.
