Life Span Motor Development, Seventh Edition With HKPropel Access, is a leading text for helping students examine and understand how interactions of the developing and maturing individual, the environment, and the task being performed bring about changes in a person’s movements. This model of constraints approach, combined with an unprecedented collection of video clips marking motor development milestones, facilitates an unmatched learning experience for the study of motor development across the life span. The seventh edition expands the tradition of making the student’s experience with motor development an interactive one. Related online learning tools delivered through HKPropel include more than 190 video clips marking motor development milestones to sharpen observation techniques, with interactive questions and 47 lab activities to facilitate critical thinking and hands-on application. The lab activities may be assigned and tracked by instructors through HKPropel, along with chapter quizzes (assessments) that are automatically graded to test comprehension of critical concepts. The text also contains several updates to keep pace with the changing field: Content related to physcial growth and development of the skeletal, muscle, and adipose systems is reorganized chronologically for a more logical progression. New material on developmental motor learning demonstrates the overlap between the disciplines of motor development and motor learning. New insights into motor competence help explain the relationship between skill development and physical fitness. The text helps students understand how maturational age and chronological age are distinct and how functional constraints affect motor skill development and learning. It shows how the four components of physical fitness—cardiorespiratory endurance, strength, flexibility, and body composition—interact to affect a person’s movements over the life span, and describes how relevant social, cultural, psychosocial, and cognitive influences can affect a person’s movements. This edition comes with 148 illustrations, 60 photos, and 25 tables—all in full color—to help explain concepts and to make the text more engaging for students. It also retains helpful learning aids including chapter objectives, a running glossary, key points, sidebars, and application questions throughout each chapter. Life Span Motor Development, Seventh Edition, embraces an interactive and practical approach to illustrate the most recent research in motor development. Students will come away with a firm understanding of the concepts and how they apply to real-world situations. Note: A code for accessing HKPropel is not included with this ebook but may be purchased separately.
Revised and updated throughout, the second edition of Energy-Efficient Electric Motors provides guidelines for picking and using electric motors on an energy conservation and life-cycle cost basis - emphasizing both single- and three-phase motors in the 1- to 200-hp range that offer maximum opportunities for energy savings.;Maintaining the features of the first edition, this concise resource: explains current improvements in electric motor capabilities and recently adopted NEMA energy-efficient motor standards; contains a new section about the power factor with nonlinear loads; covers the performance of polyphase induction motors supplied by adjustable frequency power supplies for several types of loads, presents information on numerous kinds of power semiconductors used in variable-frequency power supply systems; provides expanded coverage comparing various types of adjustable speed drives when applied to constant torque and variable torque loads; and contains a new summary checklist criteria for selecting induction motors for adjustable frequency drive systems.;Generously illustrated with nearly 200 figures and tables, the second edition of Energy-Efficient Electric Motors is timely reading for electrical, electronics, mechanical, consulting, specifying, and plant engineers; plant and purchasing managers; original equipment, heating, ventilating, and air-conditioning manufacturers; and continuing-education courses in these disciplines.
A career engineer at Studebaker, Harold E. Churchill became president of the recently merged Studebaker-Packard Corporation in 1956, at a time when finances were shaky and an aging product line was losing ground to the Big Three. Quickly launching a program of "realism and common sense," he focused the company's energies on a few selected market segments where he saw opportunities for gain. His vision for a compact economy car led to the Lark, the hit model that Studebaker desperately needed. This thorough examination of Churchill's leadership of Studebaker-Packard draws upon Board of Directors minutes, internal documents, oral histories and media reports in constructing a detailed account of these crucial years. In addition to covering the cars and trucks produced under Churchill in detail, it closely traces Churchill's actions as president and analyzes his motivations, the pressures he faced, his leadership style and the success or failure of his tenure.
Providing a solid foundation in the normal development of functional movement, Functional Movement Development Across the Life Span, 3rd Edition helps you recognize and understand movement disorders and effectively manage patients with abnormal motor function. It begins with coverage of basic theory, motor development and motor control, and evaluation of function, then discusses the body systems contributing to functional movement, and defines functional movement outcomes in terms of age, vital functions, posture and balance, locomotion, prehension, and health and illness. This edition includes more clinical examples and applications, and updates data relating to typical performance on standardized tests of balance. Written by physical therapy experts Donna J. Cech and Suzanne "Tink" Martin, this book provides evidence-based information and tools you need to understand functional movement and manage patients' functional skills throughout the life span. - Over 200 illustrations, tables, and special features clarify developmental concepts, address clinical implications, and summarize key points relating to clinical practice. - A focus on evidence-based information covers development changes across the life span and how they impact function. - A logical, easy-to-read format includes 15 chapters organized into three units covering basics, body systems, and age-related functional outcomes respectively. - Expanded integration of ICF (International Classification of Function) aligns learning and critical thinking with current health care models. - Additional clinical examples help you apply developmental information to clinical practice. - Expanded content on assessment of function now includes discussion of participation level standardized assessments and assessments of quality-of-life scales. - More concise information on the normal anatomy and physiology of each body system allows a sharper focus on development changes across the lifespan and how they impact function.
Design Engineer's Sourcebook provides a practical resource for engineers, product designers, technical managers, students, and others needing a design-oriented reference. This volume covers the mathematics, mechanics, and materials properties needed for analysis and design, with numerous examples. A wide range of mechanical components and mechanisms are then covered, with case studies interspersed to show real engineering practice. Manufacturing is then surveyed, in the context of mechanical design. The book concludes with information on clutches, brakes, transmission and other topics important for vehicle engineering. Tables, figures and charts are included for reference.
