This textbook introduces and explains the basic concepts on which statics is based utilizing real engineering examples. The authors emphasize the learning process by showing a real problem, analyzing it, simplifying it, and developing a way to solve it. This feature teaches students intuitive thinking in solving real engineering problems using the fundamentals of Newton's laws.
This book also:
- Stresses representation of physical reality in ways that allow students to solve problems and obtain meaningful results
- Emphasizes identification of important features of the structure that should be included in a model and which features may be omitted
- Facilitates students' understanding and mastery of the flow of thinking practiced by professional engineers

Описание: In this book, an attempt to augment the physical representations about some phenomena of the quantum electrodynamics in relation to medical physics is made. First of all, the physical theory of an electromagnetic radiation quantum is developed. The Schrodingers equation for a quantum is found and solved. The quantum length, how it is radiated, what the role of a vacuum in these processes, etc. are shown. The explanation of the quark confinement reason (impossibility to leave a hadron by a quark) is given. With the help of the Feynmans diagram method, some physical processes playing an important role in medical physics are analysed in detail: annihilation of the electrons and positrons in photons, breaking of the electrons in an electric field of a nucleus, changing of the quantum polarisation direction at the interaction site with molecules, etc. The use of Feynmans diagram method makes the loss of some physical phenomena accompanying a researched physical process possible, in particular the Doppler effect. On the basis of the quantum electrodynamics, the modern methods of diagnostics are investigated: a positron-emission tomography and a magneto-resonant tomography. Their developmental processes are also discussed. This book will be useful to students and scientists whose interests lay in the fields of quantum electrodynamics and medical physics.

Описание: In this book, mathematical aspects of a population genetics are considered. On the basis of the Hardy - Weinberg law, the standard approach to population genetics problems is stated. Along with the standard approach, the necessity of separate research of family tree genetics and population genetics, which represent set of the family trees, is shown. Family trees are investigated by methods of discrete mathematics in a discrete time scale which is defined by alternation of generations. It is necessary to transit to a continuous time scale, continuous functions, therefore the Hardy-Weinberg law is written down in the form of the differential equation of the second order. Transition to continuous functions has allowed us to receive new and certainly not trivial results in population genetics. In particular, a new approach to problems of a mutations occurrence under radiation is discussed, of a new growths occurrence, and migrations of populations under various conditions to reveal nonlinear character of inbreeding and natural selection. The book can be useful to geneticists, students-biologists, post-graduate students and everyone who is interested in problems of population genetics.

Описание: Immerse yourself in monster lore in this supplement for the world's greatest roleplaying game This is NOT just another Monster ManualVolo's Guide to Monsters provides something exciting for players and Dungeon Masters everywhere. - A deep dive into the lore behind some of D&D's most popular and iconic monsters - Dozens of monsters new to the fifth edition to include in your epic adventures - New playable races to allow you to build characters to fit nearly any type of story in your D&D game. The esteemed loremaster Volothamp Geddarm is back and he's written a fantastical dissertation, covering some of the most iconic monsters in the Forgotten Realms. Unfortunately, the Sage of Shadowdale himself, Elminster, doesn't believe Volo gets some of the important details quite right. Don't miss out as Volo and Elminster square off (academically speaking of course) to illuminate the uninitiated on creatures both common and obscure. Uncover the machinations of the mysterious Kraken Society, what is the origin of the bizarre froghemoth, or how to avoid participating in the ghastly reproductive cycle of the grotesque vargouille. Dungeon Masters and players will get some much-needed guidance as you plan your next venture, traipsing about some dusty old ruin in search of treasure, lore, and let's not forget ... dangerous creatures whose horns, claws, fangs, heads, or even hides might comfortably adorn the walls of your trophy room. If you survive. Research has never been so dangerous
