N.A. Etat : New. The number and variety of information resources available in the Internet is growing turbulently. There is also growing evidence that users are increasingly relying on Internet based information for their day to day activity and they spend considerable time in finding such information but it is very hard to get the subject specific relevant resources from the whole mass of divergent resources available on the web. Information professionals are the major role players in information access, thus known as information mediators, it is highly imperative for them to develop an appropriate means for organizing and providing quick access to relevant web resources, thereby saving the time of the users. As a solution to this rising phenomena Subject gateways evolved as a popular tool and best means to access subject specific information sources without waste in time and need to search through various websites. The present work "Planning and Designing of Subject Gateways" has been designed with the highly acclaimed and most popular multi-platform, multimedia and multi lingual Open Source Digital Library Software i.e. GSDL. This is a maiden work of its kind which focuses on the basic frame work of how to plan, design and develop a subject gateway as a basic retrieval tool to subject specific information. Therefore could be of use both as an authoritative resource and practical tool for practicing librarians, students of Library & Information Science and also for the researchers in doing furtherance of their research in field of designing and developing information retrieval mechanisms.

N.A. Etat : New. Laboratory Manual for Engineering and Physical Chemistry, aimed to provide an overview of the practical knowledge in Engineering and Physical chemistry experiments along with the fundamental chemical principles needed to understand this science. The book primarily deals with the experimental chemistry aspects of engineering, postgraduate and B.Sc(Hons) streams. It has been written to cater the needs of students in understanding the theory existing behind the practical procedures.Further the presentation provides the necessary course material in a cogent manner and the student finds relevant material in the compact collection. This book enriches the practical knowledge to the beginner?s at the industry, helps to improve their skills. This book is broadly divided into two sections. The first section is especially meant for chemistry practicals of engineering students of various universities across India and the second part is meant for students of B.Sc (Hons) and M.Sc., of various universities to acquire knowledge of physical chemistry practicals. In the beginning of section-I, the importance of chemical analysis (both qualitative and quantitative analysis) has been presented in lucid manner and twenty experiments have been dealt where as Section II deals with ten experiments. The significant feature of the book is that, at the beginning of each practical procedure the necessary fundamental theory is also incorporated for the benefit of students. Page Extent: 214.

Soft cover. Etat : New. Modern commercial sugarcane varieties are obtained through a multi-stage selection scheme requiring over a period of approximately 10 years through identification of a few elite clones from a very large population of hybrid seedlings. Lack of suitable multiplication procedure and perpetuation of systemic diseases are the serious problems in multiplying an elite genotype of sugarcane conventionally in the open field. Due limited availability of seed cane of a new variety at the time of its release and slow multiplication rate by conventional means, it takes a further period of about 10-12 years to cover the desired area for commercial cultivation. By the time the variety starts deteriorating due to biotic and abiotic stresses. It has also been realized that the growing demand of seed cane of newly released varieties cannot be fulfilled timely by the conventional methods of plant multiplication. Therefore, the use and exploitation of new biotechniques are quite essential for faster multiplication of newly released varieties. Micropropagation is currently the only realistic means of achieving rapid and large scale production of disease free planting material of newly developed varieties in order to speed up the commercialization process in sugarcane. Thus, plant tissue culture has now become the major component of biotechnology. Genetic engineering and molecular biology can be used for crop improvement through the application of various technique developed in the field of biotechnology. Several exciting developments have taken place in sugarcane biotechnology during the last 5 decades. The first edition of this book entitled ?Tissue culture based sugarcane farming? is being brought out as an introductory text covering plant regeneration in vitro using cell, tissue and organ culture. Basic aspects such as large scale micropropagation, cell culture, cellular totipotency, somatic embryogenesis and various aspects of sugarcane cultivation have also been included. In this book, comprising 29 chapters, various protocols have been described in very simple manner. The language of the text is simple and the subject matter is fully illustrated. No other book is available with such an approach covering basic to applied aspects of plant tissue culture. I hope this book will prove to be of a great use within the classroom as teaching/learning material and in the laboratory for practical and research purposes for the scientist as well as professionals in the fields of sugar industry.

Hardcover. Etat : New. The book ?Current Concepts in Crop Protection? comprising of 15 chapters has addressed the current issues and challenges of crop protection encompassing traditional practices, technological breakthroughs, ecological and economical considerations and finally sustainability concerns. The present book attempts to cover plant pathogens, insect and non-insect pests, weeds, and nematodes. The chapter on climate change has discussed the fate of biocontrol agents in global climate change scenario in addition to that of various plant pests in agroecosystem. The following chapter on nanotechnology has reviewed the latest works done in plant protection aspects. Considering the enormous work on biotechnology being carried out with regard to crop protection, two separate chapters were invited which gave a thorough update in a concise manner. Role of information and communication technology have been elaborated in chapter no. 3 and 9. The latest developments in cultural management of crop pests have been highlighted in chapter no. 6. Indigenous technical knowledge (ITK) of crop protection practiced in India has been presented in chapter no. 7. The specific set of crop protection problems and their remedies under protected cultivation has been discussed in chapter no 8. Residual toxicity of pesticides and environmental concerns are propelling the efforts in development of newer plant protection chemicals (fungicides, insecticides and herbicides) which have been mainly presented in tabular form in chapter no. 10. Nature?s bounty on crop protection in the form of various botanicals with excellent details concerning all plant pests have found place in chapter no. 11. The concept of conservation biological control has been elaborated in chapter no. 12. Crop protection with legal means at a time of increased inter-country agricultural trade and sustainability issues have been described in a lucid manner in chapter no. 13 and 15 respectively. The chapter no. 14 has dealt with the prokaryotic plant pathogen phytoplasma. The chapters in the book highlight the present crop protection scenario targeting the needs of undergraduate and postgraduate students, educationists, researchers engaged in crop protection in particular and agriculturists in general.
