Abstract
This paper is based on a novel heuristic algorithm for routing and wavelength assignment in virtual wavelength path routed WDM network. In this paper, we have considered a wavelength routed WDM optical network and the Heuristic algorithm is implemented on it. The term heuristics is used for algorithm, which finds solution among all possible ones, but they do not guarantee that the best solution will be found. Therefore they may be considered as approximate and not accurate algorithms. Heuristic algorithm has its own structure, so it never runs slowly and never gives very bad results. The results are always close to the best solution. In this paper the objective of this algorithm is to minimize the requirement of wavelength in any network topology demanded by network traffic. It also minimizes the hop length between source and destination nodes in the traffic. As wavelength and number of hops get reduced, the cost of the network also gets reduced and the resource utilization is maximized. In the first phase of this algorithm, we assigned minimum hop length to each route demanded by traffic and also assigned wavelengths to each route. In second phase of algorithm effective rerouting is performed to reduce the number of wavelengths required in the network and it also minimizes the hop length of each rerouted route. By minimizing wavelength requirement, the need of wavelength converter gets reduced, so that the network cost is also reduced. Along with the implementation of heuristic algorithm, we have found out few more parameters such as Network Congestion and Network wavelength converter requirement. This Network Congestion on each link of network is used for calculation of Network Wavelength Requirement, and Network wavelength converter Requirement

Abstract
The present paper deals with the spectral, x-ray studies of the Ni and Zn complexes with Chloramphenicol. On the basis of elemental analysis and molar conductance, formulas Ni(C11H12Cl2N2O5)WO44H2O and Zn(C11H12Cl2N2O5)WO44H2O have been suggested for the complexes under study. The geometries of the complexes have been proposed on the basis of magnetic moment, electron and infrared spectral data. TGA studies have also been carried out to know the pattern of their decomposition. The crystal system, lattice parameters, unit cell volume and number of molecules in it have been determined by x-ray diffraction data. The aim of investigation is to study coordination behavior of Ni and Zn in the presence of WO4 anion.

Abstract
—This paper utilizes the voltage source model of Unified Power Flow Controller (UPFC) and examines its abilities in mitigating the steady state stability margins of electric power system. It analyzes its behavior for different controls strategies and proposes the most efficient mode of controlling the controller for voltage stability enhancement. A systematic analytical methodology based on the concept of modal analysis of the modified load flow equations is employed to identify the area in a power system which is most prone voltage instability. Also to identify the most effective point of placement for the UPFC, a computer program has been developed using MATLAB. The results of analysis on 14 bus system is presented here as a case study.

Abstract
Logistics involves the integration of inventory, warehousing, material handling, packaging and transportation of products along with security. The era of globalization has driven attention to global systems of supplier relationships and the expansion of supply chains over national boundaries and into other continents. The Indian pharmaceutical industry is ready to become globally competitive with a potential to reach $ 57 billion by 2012. Supply chain is very critical as it maintains the complex network relationship between drug manufacturers, trading partners, wholesalers and retailers. Pharmaceutical products need temperature controlled storage and distribution under strict regulatory control in a manner ensuring no adverse effect on product quality. Although the storage conditions are maintained relatively constant, the distribution environment can vary greatly, especially when a drug product is shipped between various climatic zones in different countries challenging the quality and stability of product. “WHO good distribution practices for pharmaceutical products” guideline assists in ensuring the quality and identity of pharmaceutical products during all aspects of the distribution process. Evolution of new comprehensive supply chain dissolving the intermediation of wholesalers and distributors reduce the cost by developing lower- cost-service channel. Particular attention should be paid to products containing potentially toxic, hazardous, inflammable or narcotic products. Vehicles and equipment used to distribute pharmaceutical products should be suitable to prevent contamination and appropriately equipped to prevent exposure to conditions adversely effecting stability and packaging integrity. Successful adoption of SCM practices allows the companies to gain a bargaining power and reduce prices by five to ten percent.
