Mobile broadband services are growing rapidly as it provides freedom to the users to be online wherever they are at a competitive price and significant facilities such as increasing amounts of bandwidth, using mobile and roaming devices. The earliest version of WiMAX is based on IEEE 802.16 and is optimized for fixed and roaming access, which is further extended to support portability and mobility based on IEEE 802.16e, also known as Mobile WiMAX. This paper presented an analysis on those routing protocols designed for wireless networks. A comparison on the performance of seven routing protocol (AODV, DSR, OLSR, ZRP, TORA, GRP and DSDV) for Mobile WiMAX environment is done. The performance matrix includes Packet Delivery fraction (PDF), Throughput, End to End Delay, and number of packet dropped were identified. The study used NS2 simulator for the comparison on the performance analysis.

The early history of entrepreneurship in India reflects from the culture, customs and tradition of the Indian people. Entrepreneurship has its heredity in the occupational pursuits opted by the individual under the caste system in India. Entrepreneurship plays an important role in the economic growth and development of the nation. It is a purposeful activity which includes an initiation, promotion and distribution of wealth and service. An entrepreneur is a critical factor in economic development and an integral part of the socioeconomic transformation. The entrepreneurial career can not be developed over night. It is a risk taking activity and challenging task, needs utmost devotion, total commitment and greater sincerity with fullest involvement for his/ her personal growth and personality. Further if such activities are taken up by women, they need to put double the effort compared to men. A survey of women entrepreneurs owning different micro enterprises is initiated to understand motivational factors behind their entry into entrepreneurship. The study also focuses on the problems and challenges that emerge in women entrepreneurship. Entry of women in this male dominated field gives them a real empowerment in terms of economic independence and decision role.

Education system in India can be dated centuries back to the age of Buddha but, now there has in fact been substantial improvement in the higher education state of affairs of India in both quantitative and qualitative terms post globalization. The higher education system in India suffers from acute paucity of funds, lack of autonomy, burden of affiliation etc. It is characterized by extreme rigidity and lack of flexibility. The real weakness of the higher education is in the structure itself, and there is a need for introspection and reflection on what we have achieved and where do we go from here during the times of globalization on the other hand, the effects of globalization on education bring rapid developments in technology and communications are foreseeing changes within learning systems across the world as ideas, values and knowledge, changing the roles of students and teachers, and producing a shift in society from industrialization towards an information based society.

This article aims at analyzing the various hidden, explicit, aboveboard and shady themes of the novel. The article tackles the concepts of individuality, independence and identity crisis in the novel. A constant search for identity, which is prevalent throughout the novel, is reflected at different angles in the article.

The world’s entrance into the computer age along with web has certainly had a profound impact on our society. With increase in purchasing power, mass production, lesser costs, exponential growth in computer technology and population growth were one of the main drivers of increases in global warming and climate change. The onset of Information age is associated with the digital revolution, just as the Industrial Revolution marked the information age. Computerization of modern society has brought convenience to all aspects of human life. It seems evident that there will be both positive and negative effects on society and global environment. Computers have added a new source of heat generation and emission into environment. In spite of recent studies indicating possible threats to global warming and global climate, there is no long term data available on the amount of heat generated, emitted and dissipated into environment by computer monitors. The scope of this research work is to experimentally measure the heat generated by computer monitors during on (sleep/Idle) mode and working mode. For this research work four decimal digit temperature measurement test instrument was designed and exclusively fabricated. A special air locked container was also fabricated for conducting heat emission experiments on computer monitors. Population and computers projections for India, China, USA and the whole world were also included in this research work for 2050. An attempt is made to indicate amount of heat generated, emitted and dissipated into environment by India, China, USA and entire world by computer monitors at present and projections for 2050.

The research aimed is to analyze the relation among organizational culture, work satisfaction, motivation toward organizational commitment and performance. We took samples of respondent from affiliates of AALI Plantation in Indonesia. The analysis tool is Structural Equation Model. The result showed that organizational culture influence job satisfaction and organizational performance directly, job satisfaction affects motivation and performance, and motivation and organizational commitment have significant relationship

The present research is motivated by the changing roles of continuous improvement programs as a result of changes in organizational environments. Focus on the changing demands made on organizational infrastructure for continuous improvement program is under consideration. Visual process control is applied in a financial section of a company. The success of Six Sigma programs depends to a large extent on motivating employees, training them and coordinating their efforts in projects as well as implementing changes resulting from projects. Managers are interviewed (Total 12) and on the basis of score the improvement are analyzed.

This work deals with the vibrational spectroscopy of Hexafluorobenzene (HFB) by means of quantum chemical calculations. The FTIR and FT-Raman spectra were measured in the condensed state. The fundamental vibrational frequencies and intensity of vibrational bands were evaluated using density functional theory (DFT) with the standard B3LYP / 6-311+G** basis set combinations, and was scaled using various scale factors which yields a good agreement between observed and calculated frequencies. The vibrational spectra were interpreted with the aid of normal coordinate analysis based on scaled quantum mechanical force field. The results of the calculations were applied to simulated infrared and Raman spectra of the title compound, which showed excellent agreement with the observed spectra.

Schiff bases are typically synthesized by the condensation of amines and a carbonyl bearing compounds. Schiff bases are important intermediates for the synthesis of various bioactive compounds.These compounds and their metal complexes are very important as catalysts in various biological systems, polymers, dyes and medicinal and pharmaceutical fields. Furthermore, they are reported to show a variety of biological activities including antibacterial and antifungal activities.

In order to assess the antioxidant activity of the basidiocarp of mushrooms, viz., Boletus edulis, Ganodrema tsugae and Micoporus xanthopus., an invitro investigation was carried out. The result of the study revealed that the enzymatic antioxidants like catalase and peroxidase were recorded maximally in the basidiocarp of the fungus M. xanthopus (34.190 U mg^-1 and 116.53 U mg^-1 enzyme protein) and minimally in G. tsugae and B. edulis (9.602 U mg^-1 and 66.59 U mg?1 enzyme protein). The non-enzymatic antioxidants like ascorbic acid (vitamin C) and tocopherol (vitamin E) were much pronounced in B. edulis basidiocarp (17.15 µg^-1 and 56.13 µg g^-1 ) compared to M. xanthopus and G. tsugae (17.15 µg^-1 and 26.07 µg g^-1 ) respectively.
