This book was released on 2021-10-25 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early 20th century, tanned skin was associated with good health. However, people began to protect themselves against potential overexposure to avoid sunburns. Around 1945, the first sunscreen products became available. In the years to follow, a vast number of different sunscreen filters and frameworks regulating filter substances and preparations, and methods characterizing sunscreen products were developed. The perception regarding the tasks of sunscreen products changed several times – initially it was promoted as a lifestyle product, then as a skin cancer preventive means, and more recently also for anti-aging. Different purposes and the widespread use of these products have led to myriad studies and a wealth of information. In this volume, the editors present a current collection of information analyzing and discussing issues related to sunscreen products and their use. These include challenges regarding the ideal sunscreen product including filter selection and formulation issues, measurement methods, performance characterization, safety, and regulatory issues. Further papers address topics related to the use of sunscreen products in everyday life, in vulnerable cohorts and outdoor workers. Controversial topics such as environmental effects of sunscreen products and the risks and benefits of UV radiation in the context of skin cancer, vitamin D and cardiovascular and metabolic health are also covered.
Download or read book Light and Life in the Sea written by Marine Biological Association of the United Kingdom and published by Cambridge University Press. This book was released on 1990-05-17 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Without light there would be no life in the sea. Since the seas were the cradle for the evolution of all life forms, the theme of this book is central to our understanding of the interaction between living organisms and their environments. To express the breadth of research in this area, leading experts in topics as diverse as satellite imagery and molecular biology have contributed to this collection of essays on light and life in the sea, first published in 1990. Intended for all with an interest in the marine environment, this book aims to present the reader with a sampler of the exciting research that is underway and to provide an introduction to its broad compass.

Available in PDF, EPUB and Kindle. Book excerpt: The Encyclopedia of Sustainability Science and Technology (ESST) addresses the grand challenge for science and engineering today. It provides unprecedented, peer-reviewed coverage in more than 550 separate entries comprising 38 topical sections. ESST establishes a foundation for the many sustainability and policy evaluations being performed in institutions worldwide. An indispensable resource for scientists and engineers in developing new technologies and for applying existing technologies to sustainability, the Encyclopedia of Sustainability Science and Technology is presented at the university and professional level needed for scientists, engineers, and their students to support real progress in sustainability science and technology. Although the emphasis is on science and technology rather than policy, the Encyclopedia of Sustainability Science and Technology is also a comprehensive and authoritative resource for policy makers who want to understand the scope of research and development and how these bottom-up innovations map on to the sustainability challenge.
Download or read book Textbook of Prosthodontics written by Deepak Nallaswamy and published by JP Medical Ltd. This book was released on 2017-09-30 with total page 1417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prosthodontics is the subspecialty of dentistry that deals with the aesthetic restoration and replacement of teeth. The second edition of this textbook has been fully revised and updated to provide undergraduates with the latest advances in the field of prosthodontics. Divided into six sections, each part provides in depth detail on a specific type of prosthesis – complete dentures, removable partial dentures, fixed partial dentures, maxillofacial prosthesis, implants, and dental materials. The section on implants has been completely reorganised with the addition of new chapters, and the section on dental materials is brand new to this edition. The book includes discussion on anatomical land marks and lab procedures, as well as evidence based clinical practice and operating techniques. More than 3000 clinical photographs, diagrams, concept maps and charts enhance learning and enable quick revision. Key points Fully revised, second edition providing latest advances in prosthodontics Features brand new section on dental materials Highly illustrated with more than 3000 clinical photographs, diagrams and charts Previous edition (9788180611995) published in 2006

Download or read book The Visual System of Fish written by Ron Douglas and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: A question often asked of those of us who work in the seemingly esoteric field of fish vision is, why? To some of us the answer seems obvious - how many other visual scientists get to dive in a tropical lagoon in the name of science and then are able to eat their subjects for dinner? However, there are better, or at least scientifically more acceptable, reasons for working on the visual system of fish. First, in terms of numbers, fish are by far the most important of all vertebrate classes, probably accounting for over half (c. 22 000 species) of all recognized vertebrate species (Nelson, 1984). Furthermore, many of these are of commercial importance. Secondly, if one of the research aims is to understand the human visual system, animals such as fish can tell us a great deal, since in many ways their visual systems, and specifically their eyes, are similar to our own. This is fortunate, since there are several techniques, such as intracellular retinal recording, which are vital to our understanding of the visual process, that cannot be performed routinely on primates. The cold blooded fish, on the other hand, is an ideal subject for such studies and much of what we know about, for example, the fundamentals of information processing in the retina is based on work carried out on fish (e. g. Svaetichin, 1953).
Download or read book Animal Signals written by Yngve Espmark and published by Tapir Academic Press. This book was released on 2000 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: How can we explain the peacock's beautiful tail decorations, or the wonderful song of the nightingale? Why are some smells nice and others nasty? How do animals signal their intentions and qualities to potential partners? How do offspring tell parents about their needs? Are signals tuned to the environment, and to the mental abilities of receivers? Essential for understanding how animals cope with their ecological and social environment, the study of animal signals is one of the most active research areas in evolutionary biology. Understanding the signalling systems of nature has wide-ranging relevance including biological conservation and human communication. Written by international scientists, this is a comprehensive overview of the fascinating diversity of animal signals and signalling functions. Combining reviews and research, the book is aimed at both students and professional scientists.
