Learning Mathematics - Class 6 has been written by Prof. M.L. Aggarwal in accordance with the latest syllabus of the NCERT and Guidelines issued by the CBSE on Comprehensive and Continuous Evaluation (CCE). The subject matter has been explained in a simple language and includes many examples from real life situations. Questions in the form of Fill in the Blanks, True/False statements and Multiple Choice Questions have been given under the heading ‘Mental Maths’. Some Value Based Questions have also been included to impart values among students. In addition to normal questions, some Higher Order Thinking Skills (HOTS) questions have been given to enhance the analytical thinking of the students. Each chapter is followed by a Summary which recapitulates the new terms, concepts and results.
Second edition Industrial wastewater treatment, A.D. Patwardhan
Industries use a large number of substances in their manufacturing processes and also generate solid residues, liquid effluents and gaseous emissions as wastes. These may be organic, inorganic, inert or toxic compounds but are hazardous in nature and thus need to be treated and disposed off suitably in order to maintain ecological balance of the environment. Also, wherever feasible, recovery of useful by-products, recycling of water and reuse of wastewater (with or without treatment) save resources and reduce production cost. In view of the above, the book has been written, and now updated in the second edition to discuss sources, characteristics and treatment of wastewater produced in industries such as textiles, dairy, tanneries, pulp and paper, fertilizer, pesticide, organic and inorganic chemicals, engineering and fermentation. Many flow diagrams have been included to illustrate industrial processes and to indicate the sources of wastewater. After describing treatment for individual factories, the author discusses the more advanced and economical common effluent plants. The text uses simple and straightforward language and makes the presentation attractive. This book should prove extremely useful to undergraduate students of civil and chemical engineering and postgraduate students of environmental science and engineering. Industrial design consultants will also find the book very handy. To the Greens, it may offer some of the solutions to their concerns. NEW TO THE SECOND EDITION • Includes the concept of Zero Liquid Discharge (ZLD) in Chapter 1 and provides further information in Appendix A. • Incorporates brief information about plasma gasification technique in Appendix B and advanced oxidation technique in Chapter 3. • Includes ecological aspects of pollution control and a reference on benthal load in Chapter 4. • Provides information on jute retting in Chapter 6. • Incorporates topics such as photocatalytic degradation of phenols from coke oven wastes, HCl recovery from pickling operations and e-waste han
Third edition Waste water treatment, M.N.Rao, A.K.Datta
This book is intended for civil and chemical engineering students opting for a specialised course in environmental engineering. In the recent past, many environment questions, once of interest mainly to scientists and engineers, have become serious issues of public policy and have sustained a steadily growing public awareness. Concerns about environmental pollution and waste water treatment are visible worldwide.
Problem in General Physics
The the ‘Classic Text Series’ is the only of its kind selection of classic pieces of work that started off as bestseller and continues to be the bestseller even today. These classic texts have been designed so as to work as elementary textbooks which play a crucial role in building the concepts from scratch as in-depth knowledge of concepts is necessary for students preparing for various entrance examinations.This book on Problems in General Physics containingabout 1900 problems with hints for solving the most complicated ones has been designed for students studying advanced course in Physics. The book has been divided into six parts covering Physical Fundamentals of Mechanics, Thermodynamics & Molecular Physics, Electrodynamics, Oscillations & Waves, Optics and Atomic & Nuclear Physics, each segregated into number of chapters. Each chapter in the book opens with a time-saving summary of the principal formulas for the relevant area of physics. As a rule the formulas are given without detailed explanation. Explanatory notes are given in those cases where misunderstandings may arise. The author has used all formulas in the SI system, except in Part six where the Gaussian system has been used. Also the main physical constants and tables are summarized at the end of the book along with the Periodic System of Elements and Table of Elementary Particles also covered in the book. At the beginning of each chapter summary of principal formulas has been given for clarifying relevant basic concepts. At the end of each chapter, unsolved practice exercises have been provided to help aspirants revise the concepts discussed in the chapter. Answers and Solutions to the practice exercises have been given at the end after Part six. After the answers & solutions, appendices have also been provided for better comprehension of the concepts discussed in the book.Hope this book on Problems in General Physics from the Classic Text Series will help the readers get in-depth insight intothe various problems in general physic
Programming pearls for programming in cheap price
"The first edition of Programming Pearls was one of the most influential books I read early in my career, and many of the insights I first encountered in that book stayed with me long after I read it. Jon has done a wonderful job of updating the material. I am very impressed at how fresh the new examples seem." - Steve McConnell, author, Code CompleteWhen programmers list their favorite books, Jon Bentley's collection of programming pearls is commonly included among the classics. Just as natural pearls grow from grains of sand that irritate oysters, programming pearls have grown from real problems that have irritated real programmers. With origins beyond solid engineering, in the realm of insight and creativity, Bentley's pearls offer unique and clever solutions to those nagging problems. Illustrated by programs designed as much for fun as for instruction, the book is filled with lucid and witty descriptions of practical programming techniques and fundamental design principles. It is not at all surprising that Programming Pearls has been so highly valued by programmers at every level of experience. In this revision, the first in 14 years, Bentley has substantially updated his essays to reflect current programming methods and environments. In addition, there are three new essays on (1) testing, debugging, and timing; (2) set representations; and (3) string problems. All the original programs have been rewritten, and an equal amount of new code has been generated. Implementations of all the programs, in C or C++, are now available on the Web.What remains the same in this new edition is Bentley's focus on the hard core of programming problems and his delivery of workable solutions to those problems. Whether you are new to Bentley's classic or are revisiting his work for some fresh insight, this book is sure to make your own list of favorites.
