The twin-arginine translocation (Tat) machinery present in bacterial and thylakoidal membranes is able to transport fully folded proteins. Consistent with previous in vivo data, we show that the model Tat substrate TorA-PhoA is translocated by the TatABC translocase of Escherichia coli inner membrane vesicles, only if the PhoA moiety was allowed to fold by disulfide bond formation. Although eve...

The Dynamic Source Routing protocol (DSR) is a simple and efficient routing protocol designed specifically for use in multi-hop wireless ad hoc networks of mobile nodes. Preemptive DSR(PDSR) is the modified version of DSR. The main objective of this paper is to analyze and compare the performance of Preemptive DSR and Temporarily Ordered Routing Algorithm(TORA).It discusses the effect of variat...

Cassia tora Linn. (Caesalpinaceae) is a semi-wild annual herb grown widely in different places of south-east Asia including India, Northern Australia and Americas. This plant species is well known for having potential in traditional medicine practices for the treatment of a variety of disorders and ailments ranging from simple cough, hypertension to diabetes. Recent scientific investigation rev...

This work evaluates the performance of three well known routing protocols in mobile ad-hoc networks, namely Ad-hoc On demand Distance Vector Protocol (AODV), Dynamic Source Routing (DSR) and Temporally Ordered Routing Algorithm (TORA). Two scenarios were created using OPNET and extensive simulations were made on each scenario to evaluate the performance of the three protocols. Results were pres...

The objective of the present work was extraction of polysaccharide from Senna tora L. seed and its characterization as a pharmaceutical excipient. Polysaccharide extraction was based on mechanical separation of the endosperm of seeds of Senna tora, water dissolution, centrifugation, and precipitation with acetone. Standard procedures were used to study the viscosity, micromeritic properties, an...

AIM The study was conducted to evaluate the attribution of antibacterial and antioxidant activity of methanolic extract of Cassia tora toward its growth promoting effect in broiler birds. MATERIALS AND METHODS A limit test was conducted for C. tora extract in Wistar albino rats. Phytochemical screening of methanolic extract of leaves of C. tora was carried out. In-vitro antibacterial activity...

In a MANET, the aggressive progress of research is running continuously after the important study of AODV, DSR, TORA and OLSR routing protocols. Many studies and researches are done by using different methods on these routing protocols in manner of performance evaluation. By this study every different method and simulation environment gives the different results, means every applied method give...

We have isolated three Shewanella oneidensis mutants specifically impaired in trimethylamine oxide (TMAO) respiration. The mutations arose from insertions of an ISSo2 element into torA, torR, and torS, encoding, respectively, the TMAO reductase TorA, the response regulator TorR, and the sensor TorS. Although TorA is not the sole enzyme reducing TMAO in S. oneidensis, growth analysis showed that...
