An approach to a debated rejuvenator (rasayana) of traditional Hindu ayurvedic medicine. It shows that shilajit contains two compounds viz DCPs (dibenzo - a pyrone chromoproteins) and their key nuclear components DBPs (dibenzo - a pyrones).
Experimental Biology: A Laboratory Manual provides a theoretical basis of various practical in a lucid manner at graduate and postgraduate levels. This includes Immunology, Microbiology, Animal Cell Culture, Biochemical Techniques, Separation and Analytical Techniques, Haematology, and Physiology. The methods are detailed completely in a step-by-step format that allows the students to perform experiments without reference to any secondary source. The reagents and chemicals are specified with exact methods of preparation so that no further calculations are necessary. The book contains several relevant figures, flow diagrams and charts to aid the students.
Essential for students of both undergraduate and postgraduate classes, Modern Plant Physiology addresses new developments in tissue culture, stress physiology, and secondary metabolities. This detailed and comprehensive handbook, written by a renowned figure in botanical education, focuses on many essential concepts, including: the metabolisms of nitrogen, amino acids, protein, fat, and nucleic acid; photosynthesis; photorespiration; hormones; senescence, aging and abscission; photoperiodism; and the physiology of flowering. The text offers tabulated differences between allied processes such as Fluorescence and Phosphorescence, thus providing a clear conception and better understanding of the subject matter.
Covering traditional and emerging breeding procedures, this book explores the scientific bases and details of breeding plants. It puts a special emphasis on the further refinements possible in the light of the latest developments in molecular biology. Specific breeding methods in self and cross-pollinated crops, their genetic basis and scope of further refinements, concepts and techniques of tissue culture, molecular biology and production of transgenic plants, commonly used experimental designs in plant breeding, seed production, and implications of plant breeder's rights are other highlights.
As governments, IT companies and citizens become more dependent on information systems, the need to understand and devise information security systems has become very important. This title takes a practical approach to information security with emphasis on developing skills required for facing modern security related challenges. The book's organization is based on a common body of knowledge for security domain. Although this book is focused on practical issues, the fundamental principles have not been ignored. The book will be useful for IT professionals, students of MCA, M.Sc. (Computer Science), M.Sc. (IT), and faculty of Computer Science and Engineering Departments of various institutes and universities.
Bridge Superstructure deals with the behaviour of different types of bridge decks under different systems of loading. Mathematical modeling and the behaviour of different types of bridge decks are clearly explained. Solid slab, voided slab and skew slab bridge decks are detailed out for analysis and design. Box girder bridges is specially discussed for better understanding of its behaviour and its design. Special points relating to creep and shrinkage effects in continuous bridge decks are explained. Bridge bearings, expansion joints and appurtenances of different types are explained with respect to their place of use and their functions. A few methods of erection of bridge decks of simply supported spans or continuous spans are presented to give a good understanding of such possibilities.
