Languages : en
Pages : 388

Book Description
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.

Prevention of Skin Cancer

Prevention of Skin Cancer PDF Author: David Hill
Publisher: Springer Science & Business Media
ISBN: 9401705119
Category : Medical
Languages : en
Pages : 328

Book Description
Our series Cancer Prevention - Cancer Control continues to address the causes and prevention of cancer. In this volume, Hill, Elwood, and English bring together a rich resource summarizing the state of science underpinning the primary prevention of skin cancer. While skin cancer causes an increasing burden, particularly in populations of European origin, our understanding of the role of sun exposure together with the genetic components of skin cancer continues to grow. Given the emphasis on evidence-based medicine and public health prevention efforts, it is noteworthy that, although we can all access the same evidence base, countries around the world have had remarkably different responses to the application of this knowledge to prevent skin cancer. The outstanding contribution of the Australian public health community to the scientific understanding of skin cancer etiology and the translation of this knowledge into national prevention efforts uniquely positions the editors to compile this volume focused on the primary prevention of skin cancer. In so doing they draw on an international team of authors to present a “state of the science” summary of skin cancer prevention and to identify those areas where uncertainty remains. To achieve successful prevention of cancer we must translate our scientific knowledge base into effective prevention programs. This book offers the reader keen insights into the depth of our understanding of etiologic pathways for skin cancer. This etiologic science base is complemented by rigorous prevention science placing emphasis on the social context for effective and sustained prevention efforts.

pH of the Skin: Issues and Challenges

pH of the Skin: Issues and Challenges PDF Author: C. Surber
Publisher: Karger Medical and Scientific Publishers
ISBN: 3318063851
Category : Medical
Languages : en
Pages : 214

Book Description
The concept of expressing acidity as the negative logarithm of the hydrogen ion concentration was defined and termed pH in the beginning of the 20th century. The general usefulness of the pH concept for life science was recognized and later gained importance to analytical research. Reports on results of pH measurements from living skin established the term acid mantle - the skin's own protective shield that maintains a naturally acid pH. It is invisible to the eye but crucial to the overall wellbeing of skin. Chronic alkalization can throw this acid mantle out of balance, leading to inflammation, dermatitis, and atopic skin diseases. It is therefore no surprise, that skin pH shifts have been observed in various skin pathologies. It is also obvious that the pH in topically applied preparations may play an important role. Optimal pH and buffer capacity within topical preparations not only support stability of active ingredients and auxiliary materials, but may also increase absorption of the non-ionized species of an acidic or a basic active ingredient. They may even open up opportunities to modify and "correct" skin pH and hence accelerate barrier recovery and maintain or enhance barrier integrity. Further efforts are needed to standardize and improve pH measurements in biological media or pharmaceutical/cosmetic vehicles to increase and ensure quality, comparability, and relevance of research data. In this volume, we present a unique collection of papers that address past, present and future issues of the pH of healthy and diseased skin. It is hoped that this collection will foster future efforts in clinical and experimental skin research.

New Challenges and Solutions for Renewable Energy

New Challenges and Solutions for Renewable Energy PDF Author: Paul Midford
Publisher: Springer Nature
ISBN: 3030545148
Category : Political Science
Languages : en
Pages : 412

Book Description
This book identifies second stage challenges and opportunities for expanding renewable energy into a mainstay of electricity generation that can replace fossil fuels and nuclear power, comparing Japan with several countries in East Asia and Northern Europe. Environmentally sustainable renewable energy technologies have now overtaken fossil fuel and nuclear technologies in terms of total global investment, and the costs of these technologies and related ones (e.g. storage batteries) are rapidly falling. Yet renewable energy use varies greatly from country to country. Major second stage obstacles to replacing fossil and nuclear-fueled electricity generation include the lack of electricity grid capacity and storage assets. Opportunities and solutions include expanding grids regionally and internationally, building flexible smart grids that offer better demand management, and policies that promote the expansion of storage assets, especially grid batteries and hydrogen. In addition, two key factors – electricity market restructuring through unbundling transmission from electricity generating companies; and electricity market liberalization, especially for retail customers – allow consumers to choose power companies based not only on price, but also on method of generation, especially fossil or nuclear generation versus renewable energy.

Automated Machine Learning

Automated Machine Learning PDF Author: Frank Hutter
Publisher: Springer
ISBN: 3030053180
Category : Computers
Languages : en
Pages : 223

Book Description
This open access book presents the first comprehensive overview of general methods in Automated Machine Learning (AutoML), collects descriptions of existing systems based on these methods, and discusses the first series of international challenges of AutoML systems. The recent success of commercial ML applications and the rapid growth of the field has created a high demand for off-the-shelf ML methods that can be used easily and without expert knowledge. However, many of the recent machine learning successes crucially rely on human experts, who manually select appropriate ML architectures (deep learning architectures or more traditional ML workflows) and their hyperparameters. To overcome this problem, the field of AutoML targets a progressive automation of machine learning, based on principles from optimization and machine learning itself. This book serves as a point of entry into this quickly-developing field for researchers and advanced students alike, as well as providing a reference for practitioners aiming to use AutoML in their work.

The Surgeon General's Call to Action to Prevent Skin Cancer

The Surgeon General's Call to Action to Prevent Skin Cancer PDF Author: U.s. Department of Health and Human Services
Publisher: Createspace Independent Publishing Platform
ISBN: 9781502903853
Category : Medical
Languages : en
Pages : 112

Book Description
Skin cancer is the most commonly diagnosed cancer in the United States, yet most cases are preventable. Every year in the United States, nearly 5 million people are treated for skin cancer, at an estimated cost of $8.1 billion. Melanoma, the most deadly form of skin cancer, causes nearly 9,000 deaths each year. Despite recent efforts to address risk factors, skin cancer rates continue to rise. While those with lighter skin are more susceptible, anyone can get skin cancer—and it can be serious, even deadly. Almost all of the conditions can be caused by unnecessary ultraviolet (UV) radiation exposure, usually from excessive time in the sun or from the use of indoor tanning devices. It is alarming that every year, nearly one out of every three young white women aged 16–25 engages in indoor tanning. It's important to shatter the myth that tanned skin is a sign of health. And a “base” tan is not a “safe” tan. Tanned skin is damaged skin. Understanding the risk of UV exposure is crucial to protecting ourselves and our loved ones. That is why “The Surgeon General's Call to Action to Prevent Skin Cancer” is important for all of us. It outlines action steps we can all take—as individuals, parents, educators, employers, policy makers, health care professionals, and communities—to reverse this alarming trend. As a nation, we can all do more to address skin cancer as a serious public health challenge. Everyone is urged to find out more about the risk of skin cancer—and what we all can do to prevent it.

Refining Expertise

Refining Expertise PDF Author: Gwen Ottinger
Publisher: NYU Press
ISBN: 0814762611
Category : Social Science
Languages : en
Pages : 237

Book Description
Winner of the 2015 Rachel Carson Prize presented by the Society for Social Studies of Science Residents of a small Louisiana town were sure that the oil refinery next door was making them sick. As part of a campaign demanding relocation away from the refinery, they collected scientific data to prove it. Their campaign ended with a settlement agreement that addressed many of their grievances—but not concerns about their health. Yet, instead of continuing to collect data, residents began to let refinery scientists' assertions that their operations did not harm them stand without challenge. What makes a community move so suddenly from actively challenging to apparently accepting experts' authority? Refining Expertise argues that the answer lies in the way that refinery scientists and engineers defined themselves as experts. Rather than claiming to be infallible, they began to portray themselves as responsible—committed to operating safely and to contributing to the well-being of the community. The volume shows that by grounding their claims to responsibility in influential ideas from the larger culture about what makes good citizens, nice communities, and moral companies, refinery scientists made it much harder for residents to challenge their expertise and thus re-established their authority over scientific questions related to the refinery's health and environmental effects. Gwen Ottinger here shows how industrial facilities' current approaches to dealing with concerned communities—approaches which leave much room for negotiation while shielding industry's environmental and health claims from critique—effectively undermine not only individual grassroots campaigns but also environmental justice activism and far-reaching efforts to democratize science. This work drives home the need for both activists and politically engaged scholars to reconfigure their own activities in response, in order to advance community health and robust scientific knowledge about it.

Chesapeake Bay Blues

Chesapeake Bay Blues PDF Author: Howard R. Ernst
Publisher: Rowman & Littlefield Publishers
ISBN: 0742573036
Category : Nature
Languages : en
Pages : 219

Book Description
The Chesapeake Bay restoration effort has been touted as the nation's premier environmental restoration program. Yet the Bay and the living systems it supports remain in dismally poor condition, with fisheries in decline and drinking water in danger. This book addresses the Chesapeake Bay as a political problem and reveals how the political process has worked against the interests of science, the public, and environmental advocates all at once. Author Howard Ernst shows that the forces driving environmental degradation are sown deeply into the political soul of America, posing menacing challenges to those fighting to restore large ecosystems like the Chesapeake Bay. The book serves as a political roadmap for the future, suggesting how a different course of policy action is needed to 'Save the Bay.'
