Due to the prohibitive cost of synthetic pesticides and the problems of environmental pollution caused by continuous use of these chemicals, there is a renewed interest in the use of botanicals for crop protection. Agricultural entomologists, nematologists, and pathologists the world over are now actively engaged in research into the use of plants to fight agricultural pests and diseases, and to reduce the losses caused by them. Botanical Pesticides in Agriculture reviews the research on botanical pesticides used to combat losses due to pests of agricultural importance, with special attention focused on the use of higher plants. This book will serve as the baseline reference work for future research, and many of the botanicals discussed, such as neem, bael, begonia, pyrethrum, tobacco, karanj, and mahuwa, may become integral parts of pest control programs currently being developed. It is believed that botanical pesticides will minimize the undesirable side effects of synthetic pesticides and help preserve the environment for future generations.

Book describes the basic techniques that are used in molecular biology. These techniques includes various DNA manipulation techniques, cloning and bacterial growth. This book also describes the Green Fluorescent Gene, one of the novel achievements in the field of science. The reason for writing this book is that in our graduation and post graduation we heard about various molecular biology techniques but we know very little about these techniques. And even we know the techniques we are not much aware about the principle and the protocols of the techniques. I am writing this book for the graduate and post graduate students who want to know basic molecular techniques and also their protocols so that they can use it in their laboratory doing their work. Many researchers can also get help from this book.

Every year for the past few decades during the Southern Hemisphere spring, chemicals southern polar region to be destroyed rapidly and severely. Due to depletion of Ozone UV-R reaches on the earth. Solar UV-R has been divided into UV-A(320-400nm), UV-B(290-320) and UV-C(100-290) regions. UV-B has the more energetic radiation and is more strongly absorbed by the day time to latitude, thickness of the atmosphere and the ozone layer altitude and cloud cover. UV-B radiation is harmful to living organisms and has detrimental effect on plant growth, development and physiology. Another effect of UV-B enhancement on plants includes reduction in yield and quality, alternation in species competition, decrease in photosynthetic activities, susceptibility to disease and changes in plants structure and pigmentation. Some species show sensitivity to present level of UV-B radiation while other are apparently unaffected by rather massive UV enhancements.

The book titled 'Understanding Play Therapy' is a quite good and handy literature for learning, teaching and practicing play therapy on children, adolescents, adults as well as persons with special needs. It provides good information in relation to historical foundation upto current status of play therapy. The students, interns and qualified professionals of clinical psychology, child psychology and developmental psychology and other health professionals of pediatrics can use this book as a good source of learning play therapy and its applications in health intervention as well as non-clinical behavioural problems. In addition, the book also includes how parents can be useful and helpful while dealing with children through play therapy. The author's approach in presenting the issues related to play therapy is praiseworthy as it ensures a comprehensive understanding of play therapy for knowledge and practice.
