Obesity is a modern day epidemic and affects all parts of world and India is of no exception. Obesity has its origin in early childhood. It has fatal effects on cardiovascular system, respiratory system, gastrointestinal system etc. Pathogenesis of obesity is multi-factorial involving interaction of genetic, neuro-endocrine, metabolic, psychological, environmental and socio-cultural factors. Mutation of leptin is associated with obesity. Genetic syndromes like Prader- Willi syndrome, Bradet- Biedl syndrome, Cohen syndrome etc are also known to be associated with obesity.A strong correlation between body mass index (BMI) of adult life and birth weight was noted.Sedentary lifestyles like viewing television, playing games in computers instead of playing outdoor games lead to an increase in incidence of obesity.Multiple co-morbidities of obesity were identified. Metabolic syndrome includes obesity, dyslipidemia, impaired glucose tolerance and hypertension.
Through its engaging and unusual problems, this book demonstrates methods of reasoning necessary for learning number theory. Every technique is followed by problems (as well as detailed hints and solutions) that apply theorems immediately, so readers can solve a variety of abstract problems in a systematic, creative manner. New solutions often require the ingenious use of earlier mathematical concepts - not the memorization of formulas and facts. Questions also often permit experimental numeric validation or visual interpretation to encourage the combined use of deductive and intuitive thinking. The first chapter starts with simple topics like even and odd numbers, divisibility, and prime numbers and helps the reader to solve quite complex, Olympiad-type problems right away. It also covers properties of the perfect, amicable, and figurate numbers and introduces congruence. The next chapter begins with the Euclidean algorithm, explores the representations of integer numbers in different bases, and examines continued fractions, quadratic irrationalities, and the Lagrange Theorem. The last section of Chapter Two is an exploration of different methods of proofs. The third chapter is dedicated to solving Diophantine linear and nonlinear equations and includes different methods of solving Fermat´s (Pell´s) equations. It also covers Fermat´s factorization techniques and methods of solving challenging problems involving exponent and factorials. Chapter Four reviews the Pythagorean triple and quadruple and emphasizes their connection with geometry, trigonometry, algebraic geometry, and stereographic projection. A special case of Waring´s problem as a representation of a number by the sum of the squares or cubes of other numbers is covered, as well as quadratic residuals, Legendre and Jacobi symbols, and interesting word problems related to the properties of numbers. Appendices provide a historic overview of number theory and its main developments from the ancient cultures in Greece, Babylon, and Egypt to the modern day. Drawing from cases collected by an accomplished female mathematician, Methods in Solving Number Theory Problems is designed as a self-study guide or supplementary textbook for a one-semester course in introductory number theory. It can also be used to prepare for mathematical Olympiads. Elementary algebra, arithmetic and some calculus knowledge are the only prerequisites. Number theory gives precise proofs and theorems of an irreproachable rigor and sharpens analytical thinking, which makes this book perfect for anyone looking to build their mathematical confidence.
