Assessing Bacterial Growth Potential in Seawater Reverse Osmosis Pretreatment: Method Development and Applications (IHE Delft PhD Thesis Series)

by Almotasembellah Abushaban

Seawater desalination is increasingly being used as a means to augment freshwater supplies in regions with high water stress, and reverse osmosis is increasingly the technology of choice because of the low energy consumption. However, seawater reverse osmosis (SWRO) systems suffer from various types of fouling, which can increase energy consumption and the use of chemicals during SWRO operation. In practice, pre-treatment systems are put in place to reduce the particulate and biological fouling potential of SWRO feed water. However, simple, reliable and accurate methods to assess the extent to which biological fouling potential is reduced during pre-treatment are not available for seawater. This research developed a new method to measure bacterial growth potential (BGP) using the native bacterial consortium in seawater. New reagents to extract and detect ATP in microbial cells were specifically developed for seawater. The new lysis and detection reagents overcame the salt interference in seawater and allow low detection of total ATP, free ATP and microbial ATP in seawater. Incorporating a filtration step further increased the sensitivity of the method six fold, enabling ATP detection of ultra-low levels of microbial ATP in seawater. The newly developed ATP-based BGP method was applied to monitor and assess the pre-treatment of five full-scale seawater desalination plants around the world. A good correlation was observed between BGP measured in SWRO feed water and the pressure drop increase in the SWRO systems, suggesting the applicability of using the ATP-based BGP method as a biofouling indicator in SWRO. Furthermore, a safe level of BGP ( In the future, on-line monitoring of BGP in SWRO feed water may further reduce the consumption of chemicals and energy and improve the overall sustainability of seawater desalination by reverse osmosis.

by Manuel Abrunhosa António Chambel Silvia Peppoloni Helder I. Chaminé

This book gathers the peer-reviewed proceedings of the 1st congress on Geoethics & Groundwater Management (GEOETH&GWM'20), held in Porto, Portugal, in an online format on 18-22 May 2020. Hosted in School of Engineering (ISEP), Polytechnic of Porto based on Porto city (a UNESCO World Heritage Site), the international conference focused on what has now been dubbed “hydrogeoethics”, a novel transdisciplinary, scientific field integrating all dimensions of geoethics in groundwater science and practice. Given its scope, the book is of interest to all researchers and practitioners in the geosciences, hydrology, water resources, hydrogeology, natural resources management, environment, engineering, law, sociology, education, philosophy, culture, among others.This joint congress is the result of a collaborative agreement between the IAH (International Association of Hydrogeologists) and IAPG (International Association for Promoting Geoethics) and reflects the need for concerted actions to achieve sustainable development.The diversity, scale, significance and increasing magnitude of anthropogenic interactions with aquifers and groundwater, which often involve conflicting values or interests, call for analysis, discussions and decisions on the part of the agents involved, e.g. groundwater scientists, policymakers, managers, organisations, professionals and citizens. This approach calls for a responsible, sustainable and human approach to groundwater use and management.The groundwater community involved in the exploration and exploitation, use and management of this increasingly vital natural resource is becoming more and more aware that ethical issues pervade all our attitudes from concept to action and need to be addressed. Diverse values and cultures, science and education, law and policies, human and natural environments and the public and the economic sectors view groundwater and its value and/or role differently. The authors believe that in a globalised and interconnected world, common ground must be found in the interest of peace, human development and sustainability. The main topics covered here include:1. Fundamentals of hydrogeoethics: cultures, principles and geoethical values on groundwater science and engineering2. Lessons for a resilient and sustainable future with hydrogeoethics: case studies of geoethics in groundwater science-engineering, profession, and management3. Scientific and humanistic components of hydrogeoethics in groundwater education and professional training 4. Socio-hydrogeology and ethical groundwater management 5. Geoethics of decision making under uncertainty and ethical issues in neglecting groundwater functioning 6. Groundwater: geological, legal, social, and ethical challenges of a unique natural resource

Sexual Nature, Sexual Culture (Chicago Series On Sexuality, History And Society)

by Paul Abramson Steven Pinkerton

In this multidisciplinary study of human sexuality, an international team of scholars looks at the influences of nature and nurture, biology and culture, and sex and gender in the sexual experiences of humans and other primates. Using as its center the idea that sexual pleasure is the primary motivational force behind human sexuality and that reproduction is simply a byproduct of the pleasurability of sex, this book examines sexuality at the individual, societal, and cultural levels. Beginning with a look at the evolution of sexuality in humans and other primates, the essays in the first section examine the sexual ingenuity of primates, the dominant theories of sexual behavior, the differences in male and female sexual interest and behavior, and the role of physical attractiveness in mate selection. The focus then shifts to biological approaches to sexuality, especially the genetic and hormonal origins of sexual orientation, gender, and pleasure. The essays go on to look at the role of pleasure in different cultures. Included are essays on love among the tribespeople of the Brazilian rain forest and the regulation of adolescent sexuality in India. Finally, several contributors look at the methodological issues in the study of human sexuality, paying particular attention to the problems with research that relies on people's memories of their sexual experiences. The contributors are Angela Pattatucci, Dean Hamer, David Greenberg, Frans de Waal, Mary McDonald Pavelka, Kim Wallen, Donald Symons, Heino Meyer-Bahlburg, Jean D. Wilson, Donald Tuzin, Lawrence Cohen, Thomas Gregor, Lenore Manderson, Robert C. Bailey, Alice Schlegel, Edward H. Kaplan, Richard Berk, Paul R. Abramson, Paul Okami, and Stephen D. Pinkerton. Spanning the chasm of the nature versus nurture debate, Sexual Nature/Sexual Culture is a look at human sexuality as a complex interaction of genetic potentials and cultural influences. This book will be of interest to a wide range of readers—from scholars and students in psychology, anthropology, sociology, and history to clinicians, researchers, and others seeking to understand the many dimensions of sexuality.

Sickening: How Big Pharma Broke American Health Care and How We Can Repair It

by John Abramson

The inside story of how Big Pharma&’s relentless pursuit of ever-higher profits corrupts medical knowledge—misleading doctors, misdirecting American health care, and harming our health. The United States spends an excess $1.5 trillion annually on health care compared to other wealthy countries—yet the amount of time that Americans live in good health ranks a lowly 68th in the world. At the heart of the problem is Big Pharma, which funds most clinical trials and therefore controls the research agenda, withholds the real data from those trials as corporate secrets, and shapes most of the information relied upon by health care professionals. In this no-holds-barred exposé, Dr. John Abramson—one of the foremost experts on the drug industry&’s deceptive tactics—combines patient stories with what he learned during many years of serving as an expert in national drug litigation to reveal the tangled web of financial interests at the heart of the dysfunction in our health-care system. For example, one of pharma&’s best-kept secrets is that the peer reviewers charged with ensuring the accuracy and completeness of the clinical trial reports published in medical journals do not even have access to complete data and must rely on manufacturer-influenced summaries. Likewise for the experts who write the clinical practice guidelines that define our standards of care. The result of years of research and privileged access to the inner workings of the U.S. medical-industrial complex, Sickening shines a light on the dark underbelly of American health care—and presents a path toward genuine reform.
