Hospitality or hotel industry as it is commonly known is an integral part of the vibrant and dynamic tourism sector. Hotel comprises of various departments based on its functions, and Rooms Division Department is one of the core departments which contributes maximum to the revenue and profitability of a hotel organisation. Accommodations Operations or Rooms Division comprises of two distinct departments that work closely in preparing the product and making it available or sale – Rooms. Housekeeping on one hand is responsible for cleanliness, upkeep and aesthetics of guest rooms and other guest areas. Whereas, Front Office is responsible for timely and optimal sale of rooms. The book also incorporates modules on Facilities Management which is a specialised term for managing premises for operational and maintenance departments. This broadens the scope of housekeeping both in terms of functions and organisations. India has witnessed an unprecedented growth in the number of hotels, retail stores, malls, office complexes, residential complexes, with this up and coming facilities management sector and this adds to the timeliness of this book. This book is a recommended text book for the course BBA in Hospitality and Facilities Management (HFM), and other hospitality courses will also find it useful. It is a handy book which integrates theoretical and practical components. Since it is for beginners studying hospitality course(s), the authors have especially taken care to keep the language simple, use figures and formats wherever possible. Contents - 1.

The present book is an outcome of long experience of teaching to undergraduate students over about 3 and 1/2 decades. A need was felt for a Textbook of Modern Physics covering the fundamental concepts of Quantum Mehanics, Statistical Physics, Solid State Physics, Atomic and Molecular Spectra, Cosmic Rays and Particle Physics in one single volume. This is what motivated the Author to write the present Book covering all these aspects. The Author hopes that the person Textbook will satisfy the needs of B.Sc. and Engineering students of almost all Indian Universities. Every effort has been made to present the basic concepts with simplicity and clerity so that the students can have the maximum comprehension of the topics. The wide range of topics contains more material than is included in the usual Textbooks. Attempts have been made to strike a balance between theory and practical applications. For those students who are desirous of learning something about advance topics, some topics such as, Raman Effect, Zeeman Effect, Superconductivity, Mossbauer Effect, Luminescemce, Nuclear Magnetic Resonance, Particle Physics, etc., have been introduced. The topics have been arranged in a logical sequence. The Theory of Relativity has been introduced in the initial stage of the Book. The present day description of most of the physical phenomena requires the use of Quantum Theory. With the development of Quantum Electrodynamics enormous progress has been made in understanding the physical world and the structure of matter. The fundamental concepts of Quantum Mechanics have therefore been introduced in two chapters which would help the students in better understanding of the physical phenomena. The fundamental concepts of Statistical Physics have been discussed in a separate chapter. This is followed by chapters on Crystal Structure and Solid State Physics. Two separate chapters have been devoted to the Detectors of Nuclear Particles and Praticle Accelerators. Chapters 17 to 20 deal with the Nucleus, Nuclear Disintegration and Nuclear Fission. The last chapter on Cosmic Rays includes the Elementary Particle Physics. The sample problems with step-by-step solutions are used to illustrate the important quantitative relationship and to increase the understanding of the basic principles. The questions at the end of each chapter are generally graded and divided into Group A and Group B. The questions in Group A are for drill exercise. The questions in Group B are aimed at descriptive answers. A large number of problems are given to test the understanding of the basic principles and some of them are challenging. Contents - 1.

The collection of chapters in this first volume of Stereochemistry – Basic to Advances in Organic Chemistry covers a range of topics that reflects both the evolution of the field of stereochemistry and the most exciting advances that presage its future. Thus, it was expressly by design that there be conceptually focused chapters on the basic principles of molecular chirality and asymmetric amplification to perfectly predict the structure of organic molecules. The goal, as in the first edition, is to give equal weight to the fundamental aspects of the study of stereochemistry. The history of organic chemistry goes back to the days of Friedrich Wohler, two centuries ago. The stereochemical underpinnings of organic chemistry were set by Louis Pasteur, and the concept of chirality was advanced by Lord Kelvin, nearly a century later. The first stereochemical notation – that of the asymmetric carbon atom – had to await the Cahn-Ingold-Prelog (CIP) R/S rules – a half-century later; it took yet another quartercentury for the E/Z configurational notation for double bonds to be formulated. Indeed, the development of organic stereochemical language has lagged and continues to lag experimental organic chemistry. In the last quarter-century or so, there have been only two seminal contributions – both by Kurt Mislow and his coworkers – ones that have clarified the basic concepts of stereotopicity and chirotopicity. Since last two decades, scientists are working very hard to establish the unknown organic structure through the correlation of stereochemical aspects and predicting its potency and efficiency based on these parameters. Also, the national universities and central examinations organizations focused more to incorporate the stereochemistry in basics to the complex molecular framework. The past years have witnessed a rapid development of biochemistry and molecular biology. The chemical structures of many complex biopolymers such as proteins and nucleic acids have been elucidated. Moreover, the understanding of the stereochemical details of many important transformations catalyzed by various metal and non-metal reactions reflect the structural complexity of organic, inorganic and biomolecular chemistry. This book provides an insightful analysis of the foundations of molecular chirality, topological chirality, definitions of chirality measures, rules applying during nomenclature, set of rules for predicting the stereochemistry, dynamic stereochemical concepts, and most important, practice with suitable examples for the readers. Nevertheless, students will often wish to pursue individual topics further. This part of the work is an attempt to present the elements of a simple, uniform and comprehensive language of organic stereochemistry. An effort has therefore been made to guide the reader to give a piece of small information that is quite useful to understand the concepts. Furthermore, in a graduate course, students should be encouraged to consult primary sources. Authors are hoping that this book will not only be of interest to specialists but will also provide general information useful to organic chemists, biochemists and molecular biologists for their research and reference work during international publications.
