Download or read book Screen Damage written by Michel Desmurget and published by John Wiley & Sons. This book was released on 2022-10-11 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: All forms of recreational digital consumption – whether on smartphones, tablets, game consoles or TVs – have skyrocketed in the younger generations. From the age of 2, children in the West clock up more than 2.5 hours of screen time a day; by the time they reach 13, it’s more than 7 hours a day. Added up over the first 18 years of life, this is the equivalent of almost 30 school years, or 15 years of full-time employment. Most media experts do not seem overly concerned about this situation: children are adaptable, they say, they are ‘digital natives’, their brains have changed and screens make them smarter. But other specialists – including some paediatricians, psychiatrists, teachers and speech therapists – dispute these claims, and many parents worry about the long-term consequences of their children’s intensive exposure to screens. Michel Desmurget, a leading neuroscientist, has carefully weighed up the scientific evidence concerning the impact of the digital activities of our children and adolescents, and his assessment does not make for happy reading: he shows that these activities have significant detrimental consequences in terms of the health, behaviour and intellectual abilities of young people, and strongly affect their academic outcomes. A wake-up call for anyone concerned about the long-term impacts of our children’s over-exposure to screens.
Download or read book HYDROGEOLOGY PROBLEMS WITH SOLUTIONS written by NANDIPATI SUBBA RAO and published by PHI Learning Pvt. Ltd.. This book was released on 2016-12-01 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical calculations are inevitably required in the field of hydrogeology and play a significant role in dealing with its various aspects. As often as not, students are seen struggling while solving numerical problems based on hydrogeology, as they find difficulty in identifying the correct concept behind the problem and the formula that can be applied to it. Also, there is a dearth of books, which help the readers in solving numerical problems of varied difficulty level and enable them to have a firm grounding in the subject of hydrogeology. The book Hydrogeology: Problems with Solutions fills this void in the finest way, and as desired, chiefly focuses on the sequential steps involved in solving the problems based on hydrogeology. It concisely covers the fundamental concepts, advanced principles and applications of hydrogeological tasks rather than overemphasising the theoretical aspects. The text comprises sixty solved hydrogeological problems, which are logically organised into ten chapters, including hydrological cycle, morphometric analysis, hydrological properties, groundwater flow, well hydraulics, well design and construction, groundwater management, seawater intrusion, groundwater exploration and groundwater quality. The practice of pedagogy of hydrogeology in yesteryears was a two-tier approach of theoretical principles with toy problems and in-situ case studies for research start-up. This book bridges the gap between routine problem-solving and state-of-the-practice for future. The book is primarily intended for the undergraduate and postgraduate students of Earth Sciences, Civil Engineering, Water Resources Engineering, Hydrogeology and Hydrology. It also serves as an excellent handy reference for all professionals.KEY FEATURES • Key Concept succinctly explores the models, methods and theoretical concepts related to each problem. • Necessary equations and formulae are specified. • Appendices and Glossary are included, leaving no scope to refer any other book. • Bibliography broadens the scope of the book.

Download or read book Polymer Matrix Composites Guidelines for Characterization of Structural Materials written by Composite Materials Handbook – 17 (CMH-17) and published by SAE International. This book was released on 2022-09-06 with total page 778 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first volume of this six-volume compendium contains guidelines for determining the properties of polymer matrix composite material systems and their constituents, as well as the properties of generic structural elements, including test planning, test matrices, sampling, conditioning, test procedure selection, data reporting, data reduction, statistical analysis, and other related topics. Special attention is given to the statistical treatment and analysis of data. Volume 1 contains guidelines for general development of material characterization data as well as specific requirements for publication of material data in CMH-17. The primary purpose of this volume of the handbook is to document industry best-practices for engineering methodologies related to testing, data reduction, and reporting of property data for current and emerging composite materials. It is used by engineers worldwide in designing and fabricating products made from composite materials. The Composite Materials Handbook, referred to by industry groups as CMH-17, is a six-volume engineering reference tool that contains thousands of records of the latest test data for polymer matrix, metal matrix, ceramic matrix, and structural sandwich composites. CMH-17 provides information and guidance necessary to design, analyze, fabricate, certify and support end items using composite materials. It includes properties of composite materials that meet specific data requirements as well as guidelines for design, analysis, material selection, manufacturing, quality control, and repair.
