Knowledge management (KM) is an emerging field, much tooted or hyped since late 1990s. However, due to the complicated nature of knowledge per se and its consequent management, it is often difficult to estimate or demonstrate the value of knowledge management. Technical libraries, with limited budget and human resources, may hesitate to follow the business sector and plunge into the uncharted sea of knowledge management. This paper suggests a pragmatic approach to the implementation of Knowledge Management for Technical libraries: utilizing the existing staffing, technology, and management structure

 Library science program prepare people to work as a Librarian or consultant or Knowledge Management Officer. Library science often termed as library studies is the interdisciplinary or multidisciplinary field that applies the practices, perspective and tool of management, information technology education and other areas of libraries :the collection, organization, preservation, dissemination of library sources and to decrease the economy of the information. Students can learn to buy, organize, store and retrieve the information. They also learn how to help people to do research and find regarding information . Nowadays information comes in many forms. Students of library science learn how to organize these different types of information so that library users feel comfortable rather than confused. Students of library science value the past and embrace the future.

 ZnO is a key technological material. ZnO is a wide band-gap (3.37 eV) compound semiconductor that is suitable for short wavelength optoelectronic applications. ZnO is a versatile functional material that has a diverse group of growth morphologies. ZnO nanostructures are easily formed even on cheap substrates such as glass and hence they have a promising potential in the nanotechnology future. ZnO nanocrystals are also attractive for sensor and biomedical application due to its bio-safety and large surface area. ZnO has some advantages over GaN among which are the availability of fairly high-quality ZnO bulk single crystals and a large exciton binding energy (_60 meV). ZnO also has much simpler crystal-growth technology, resulting in a potentially lower cost for ZnO-based devices. The present work involves study Zinc Oxide nanocrystal material by chemical precipitation method for growth of high quality ZnO nanocrystal material studying microstructure and from that correlating the microstructure to its physical, electrical and opticalproperties. At the beginning, efforts have been made to optimize the deposition conditions. It is needless to mention that the properties of the thin films depend extensively on the growth conditions, which influences its microstructure. Different parameters like substrate temperature, PH of solution, deposition time, speed of rotation etc. were carefully monitored.

 The work mainly concerns with study of the structural details, microstructure, and optical properties of the CdS thin films. Various properties like optical absorbance, dc and ac conduction behavior have been investigated in close correlation with the microstructure of the films. It involves the study of nanocrystalline CdS thin films by sol-gel spin coating deposition techniques, studying growth, microstructure, and morphology and from that correlating the microstructure to its physical, electrical and optical properties.

 MNPs of ZnO have great potential applications in the fields of optoelectronic and sensor devices. Therefore, it is very important to realize the controllable growth of MNPs of ZnO and investigate their properties.

Different parameters like substrate temperature, PH of solution, deposition time, annealing etc. were carefully monitored to decide the optimized growth condition of the MNPs.

 Modern business activities rely on extensive email exchange. Email leakages have become widespread, and the severe damage caused by such leakages constitutes a disturbing problem for organizations. We study the following problem: A data distributor has given sensitive data to a set of supposedly trusted agents (third parties). If the data distributed to third parties is found in a public/private domain then finding the guilty party is a nontrivial task to distributor. Traditionally, this leakage of data is handled by water marking technique which requires modification of data. If the watermarked copy is found at some unauthorized site then distributor can claim his ownership. To overcome the disadvantages of using watermark [2], data allocation strategies are used to improve the probability of identifying guilty third parties. The distributor must assess the likelihood that the leaked came from one or more agents, as opposed to having been

The study of semiconductor nanoparticles has been an interesting field of research for more than two decades. The confinement effect is observed for CdS particles when the particle sizes are equal to or less than 50 Å . Bulk CdS is widely used as a commercial photodetector in the visible spectrum. It is also used as a promising material for buffer layers in thin film solar cells. The optical properties of CdS nanoparticles have been extensively studied in recent years as this material exhibits pronounced quantum size effects. The present work involves the study of nanocrystalline CdS thin films by sol-gel spin coating deposition techniques, studying growth, microstructure, and morphology and from that correlating the microstructure to its physical, electrical and optical properties. To accomplish this aspiration, the entire research work is divided into two parts. At the beginning, efforts have been made to optimize the deposition conditions.
