The idea of Brahman is too easy to understand when it is a clear picture of knowledge but not that one can understand easily. To know the existence of Brahman, it is not require to devote, vibrate, emotional, believe or faith but to know exactly what is Brahman to understand the word denotes. Is it philosophical? The question makes itself critical to elaborate the existence of that limitless Ultimate Reality which the philosophers sometimes confused to find the goal and solution of the problematic Universe concerned. The Ultimate Reality is one or many; it's an important point to be remembered at the time of discussion on this valuable topic of human genetic system and how human and other beings are created from what type of things in Universe. And the Universe is one or different Universes made to find what contexts for which purpose our Universe has created. If it is created, who was the creator? All these questions may be solve in this edition with justification.
This book details the analytical processes, and interpretation of the resulting data, needed in order to achieve a comprehensive source-rock evaluation of organic-rich shales. The authors employ case studies on Permian and Cretaceous shales from various Indian basins and other petroleum-bearing basins around the world to illustrate the key features of their organic-rich shale characterization methodology. These case studies may also help to identify potential zones within shale formations that could be exploited for commercial gas and/or oil production. Given its scope, the book will be of interest to all researchers working in the field of source-rock analysis. In addition, the source-rock evaluation techniques – and the various intricacies associated with them – discussed here offer valuable material for postgraduate geology courses.

Nuclear isomers are the long-lived excited states of nuclei. Therefore, they constitute the meta-stable landscape of nuclei. The first isomer was probably identified as early as 1921. Since then, the number of isomers has been growing steadily picking up pace in recent times. Interest in nuclear isomers has grown in recent years for many reasons. The experimental capabilities to observe isomers have been expanding to cover a wider time scale. This has opened up new windows to observe and decipher the underlying nuclear structure and interactions. Further, the isomers are beginning to be seen as potential energy storage devices and nuclear clocks with a host of applications. Possible discovery of a gamma ray laser has also ignited many researches in this area. Isomers now cover the full nuclear landscape with structural peculiarities specific to each region of the nuclear chart. Exploring the nuclear isomers, therefore, provides a novel insight into the nuclear structure properties of that region. There could be many different reasons for the long lives of excited nuclear states, which lead to the classification of isomers. Isomers are broadly classified in to four classes: Spin isomers, shape isomers, fission isomers and K-isomers. Seniority isomers have also been identified which are often clubbed with the spin isomers. We discuss this classification and the underlying causes in detail. Many examples are considered to highlight the large variety of isomers. The range of half-lives covered by the isomers varies from billions of years to nano-seconds and even small. To understand this vast variation is a fascinating endeavor in itself. The angular momentum couplings, nuclear shapes, pairing etc. conspire together to give this vast range of half-lives. We go through these aspects in detail, highlighting the various selection rules at work. It is interesting that the nuclear shapes play an important role in many types of isomers. The spin isomers, which occur in spherical or, near-spherical nuclei, are generally confined to the magic numbers. Seniority isomers are largely found in semi-magic nuclei and should be explored in conjunction with the spin isomers. New developments in seniority and generalized seniority isomers are discussed in detail. As the nuclei deform; the nature of isomers changes. We take a close look into the decay properties of isomers in deformed nuclei, particularly the K isomers, the shape isomers and the fission isomers. While doing so, the theoretical and experimental developments of isomers are also addressed. A number of open questions are posed for possible new experiments and better understanding of the isomers.

The Yogacana-Vijnanavada Idealism was the last great creative synthesis of Buddhism and its position in that tradition is comparable to that of the Advaita Vedanta. In this present book the author deals with the Yogacara-Vijnanavada in all its aspects and bearings, historically, analytically and comparatively. The first two chapters show, with great clarity and sufficient detail, the origin and development of the Yogacara idealism as an outcome of those fruitful and dynamic ideas associated with the previous schools of Buddhism, especially with the Sautrantika and the Madhyamika. The originality of the Yogacara synthesis of Buddhist teachings has been clearly brought out, and the individual contributions made by the philosophers of this school, such as Asanga, Vasubandhu, Sthiramati, Dignaga, Dharmakirti and Santaraksita, have received adequate attention. The subsequent chapters, which form the core of the work, represent a constructive and critical exposition of the Yogacara metaphysics, its idealism and absolutism as well as its spiritual discipline. This reprint after a lapse of ten years fills the need of the researchers.

Indian agriculture is a symbiosis of crop and livestock production, a way of life, a tradition, which for centuries has shaped the thoughts, the outlook, the culture, and the socio-economic facet of rural life. Among agricultural scenario dairying is an important enterprise which supports the livelihoods of millions of people. It is considered as one of the subsidiary occupation of the rural people playing crucial role in the national economy in terms of generating the income and raising the employment (Mathur, 2001). In fact, agriculture is the backbone of our country in which livestock sector is an integral part of it.
