Review of A-VIEW 3.5 software

The Amrita Vishwa Vidyapeetham, situated in the State of Kerala (India), has developed the A-VIEW (Amrita Virtual Interactive e-learning World). This review of the various features of A-VIEW as a virtual classroom, from the point of view of a presenter as well as learner, commments the positive and useful features of AVIEW as well as some weaknesses

theCN.com: An Academic-cum-Social Networking Online Platform

This article is a review of theCN, an online virtual learning environment. CN is more than a learning management system, as it not only focuses on course content delivery and management, but takes it a step further by introducing the networking of courses and their content. In comparison with existing LMS’s, which are housed in closed walls with limited access to learners and instructors within institutions, used to merely manage courses online, CN is an open, free, academic and social networking framework scalable to massive numbers of learners from any place in the world within a single environment. CN is free for all to use across the globe. With some minor improvements, CN, as an LMS is surely one of very useful and helpful virtual learning technology tool available to distance learners and institutions to make learning entertaining and fruitful in achieving its learning objectives

Zinc chloride promoted efficient and facile BOC protection of amines

1168-1172Amines are efficiently protected as their BOC derivatives under mild reaction conditions when reacted with BOC anhydride in presence of ZnCl2. The present method is applicable to a variety of amines including aliphatic, aromatic as well as heteroaromatic amines. This protocol appears to be competitive and in some cases superior to previously reported procedures that work under basic conditions. </span

RecA interacts with Klenow and enhances fidelity of DNA synthesis in vitro

To understand the molecular basis of RecA-mediated DNA-repair, we tested the replicative fidelity of the large fragment of Pol I (Klenow) in RecA-DNA complexes in vitro. Klenow synthesis was error-prone in naked DNA substrates but essentially error-free in RecA coated complexes. Escherichia coli SSB, causes no such improvement in Klenow fidelity. RecA filaments promote better exonucleolytic proofreading by Klenow than on naked DNA substrates at select sites when replication is "stalled" due to a missing dNTP. Addition of RecA to pyrene sulfonylchloride-labeled Klenow resulted in a specific increase in steady-state fluorescence anisotropy and a concomitant decrease in fluorescence lifetime. These observations suggest the possibility of a direct interaction between RecA and Klenow even in the absence of DNA which may mediate the observed improvement in Klenow fidelity

Detailed circuit modelling of phone charging wireless power transfer

This paper proposes an innovative simulation software-based approach for wireless power transfer circuit modeling. The main characteristic of the methodology is the extraction of an equivalent circuit for a given positioning of the coils for a precise estimation of the losses. An important feature of the modeling is the estimation of the type of loss (conduction, eddy current and core) and their location (TX/RX winding or TX/RX core). All power losses will be represented as power dissipated by resistors present in the circuit model generated by the software. The modeling approach is tested by the comparison of loss prediction with the measurements of a 10 W wireless power transfer system in alignment and misalignment condition of the coils

Hybrid planar Litz coil optimization for phone wireless power transfer

This paper proposes an innovative receiver coil structure for wireless power charging suitable for portable devices with thickness constraint. Litz wires represent the best solution for high-efficiency wireless power transfer coil but cannot be implemented in a thin structure. In this paper will be presented and optimized planar Litz structures with narrow profile. The performances of the coils were tested with the measurements in a wireless power transfer system in alignment and misalignment conditions
