Prediction of Polymeric Membrane Separation and Purification Performances

by Alexander Anim-Mensah Rakesh Govind

This brief describes the development of a new model for realistically characterizing solution-diffusion transport mechanisms in polymeric membranes that are used for separation and purification of organic solvents. Polymeric membranes used in these environments, if not selected appropriately, undergo excessive swelling and compaction resulting in lowered performance or membrane destruction in the long-term. This brief describes the relationship between key parameters from a chemical, mechanical and thermodynamic perspective. Moreover, the authors show how this new model points membrane manufacturers, scientists, and engineers towards an understanding of how these key parameters are considered in (1) designing and manufacturing membranes for the right application, (2) designing the right test experiments to determine the long-term membrane behavior in a short time, (3) minimizing the number of experiments to determine a reliable membrane for an application and (4) selecting the right membrane with higher level of certainty. The overall benefits of the model includes saving money and time. A simplified version of the model is included to assist the reader.

Predictive Health: How We Can Reinvent Medicine to Extend Our Best Years

by Kenneth Brigham Michael M. E. Johns

ItOCOs no stretch to claim that America is in the midst of a healthcare meltdown. Care is costly and unattainable for many, and often unsatisfactory even for those who can afford treatment. The medical system focuses on treating diseases and their symptoms, and spends so much effortOCoand moneyOCoin the last miserable month of patientsOCO lives that little is left to make sure that the preceding years are as healthful as possible. In "Predictive Health," distinguished doctors Kenneth Brigham and Michael M. E. Johns propose to radically change the current model by restructuring the way patients receive care. They introduce the concept of predictive health, which will turn the existing paradigm on its headOCofocusing on prediction instead of diagnosis, and health rather than disease. Rather than treating symptoms as they arise, doctors practicing predictive health would be involved in a patientOCOs life right from the start. A drop of blood from a tiny heel prick at birth would be run through nanolabs, the resulting information assembled into a picture of the newbornOCOs health. Any potential risk factorsOCorisk for type II diabetes, genetic propensity for obesityOCowould be caught long before they became problematic, and strategies forged for treatment. In essence, health care professionals would become committed consultants, sticking with a patient for the entire course of their lives. The potential savings from this kind of partnership is staggering: the cost of lifelong health care would amount to less than the cost of a month-long stay in an early twenty-first century ICU. Interweaving descriptions of phenomenal advances in science and technology with illustrative anecdotes and personal experiences of the authorsOCO combined century in academic medicine, "Predictive Health" translates the foundations of the new biomedicine into language accessible to a general audienceOCothose who must understand the potential of the unprecedented opportunity confronting us if major change is to happen. The product of a decade-long collaboration between two of the leading figures in predictive health, "Predictive Health" offers a deeply knowledgeable, deeply humane look at the state of medicine today, and the potential for medicine tomorrow.

Predictive Microbiology in Foods

by Antonio Valero Fernando Perez-Rodriguez

Predictive microbiology is a recent area within food microbiology, which studies the responses of microorganisms in foods to environmental factors (e.g., temperature, pH) through mathematical functions. These functions enable scientists to predict the behavior of pathogens and spoilage microorganisms under different combinations of factors. The main goal of predictive models in food science is to assure both food safety and food quality. Predictive models in foods have developed significantly in the last 20 years due to the emergence of powerful computational resources and sophisticated statistical packages. This book presents the concepts, models, most significant advances, and future trends in predictive microbiology. It will discuss the history and basic concepts of predictive microbiology. The most frequently used models will be explained, and the most significant software and databases (e.g., Combase, Sym'Previus) will be reviewed. Quantitative Risk Assessment, which uses predictive modeling to account for the transmission of foodborne pathogens across the food chain, will also be covered.

Predictive Species and Habitat Modeling in Landscape Ecology

by Falk Huettmann Yolanda F. Wiersma C. Ashton Drew

Most projects in Landscape Ecology, at some point, define a species-habitat association. These models are inherently spatial, dealing with landscapes and their configurations. Whether coding behavioral rules for dispersal of simulated organisms through simulated landscapes, or designing the sampling extent of field surveys and experiments in real landscapes, landscape ecologists must make assumptions about how organisms experience and utilize the landscape. These convenient working postulates allow modelers to project the model in time and space, yet rarely are they explicitly considered. The early years of landscape ecology necessarily focused on the evolution of effective data sources, metrics, and statistical approaches that could truly capture the spatial and temporal patterns and processes of interest. Now that these tools are well established, we reflect on the ecological theories that underpin the assumptions commonly made during species distribution modeling and mapping. This is crucial for applying models to questions of global sustainability. Due to the inherent use of GIS for much of this kind of research, and as several authors' research involves the production of multicolored map figures, there would be an 8-page color insert. Additional color figures could be made available through a digital archive, or by cost contributions of the chapter authors. Where applicable, would be relevant chapters' GIS data and model code available through a digital archive. The practice of data and code sharing is becoming standard in GIS studies, is an inherent method of this book, and will serve to add additional research value to the book for both academic and practitioner audiences.

Predictive Technology in Social Media

by Cristina Fernández-Rovira

Can behaviour on social media predict future purchase patterns? Can what we click on social media foresee which political party will we vote for? Can the information we share on our wall foretell the next series I might want to watch? Can the likes on Instagram and Facebook predict the time one will spend on digital platforms in the next hour? The answer is no longer science fiction. It points to the ability of mainstream social media platforms such as Facebook and Twitter to be able to deliver specialised advertising services to highly targeted audience segments controlled by the billions of devices that flood our daily lives. At the same time, it highlights a more relevant problem: can social media guide, suggest or impose a certain behaviour or thought? Everything seems to indicate that they can do it.Predictive Technology in Social Media comprises 10 essays that reflect on the power of the predictive technology of social media in culture, entertainment, marketing, economics and politics. It shows, from a humanistic and critical perspective, the predictive possibilities of social media platforms, as well as the risks this entails for cultural plurality, everyday consumption, the monopolistic concentration of the economy and attention, and democracy. The text is an invitation to think, as citizens, about the unbridled power we have ceded to digital platforms. A new voice to warn about the greatest concentration of communicative power ever seen in the history of humanity.

Predisposed: The Left, The Right, and the Biology of Political Differences

by John R. Hibbing Kevin B. Smith John R. Alford

This thoughtfully updated revision of a classic text sheds new light on the potential sociological and biological differences that result in deep, seemingly unbridgeable political divisions.Renowned social scientists and experts in biopolitics, John R. Hibbing, Kevin B. Smith, and John R. Alford present overwhelming evidence that political opinion is shaped not just by cultural background or information bias but is rather the result of diverse psychological, physiological, and genetic traits. This new edition shifts the emphasis from differences between the political left and the right (liberals and conservatives) as they have traditionally been understood and explores specific brands of liberalism and conservatism such as ardent supporters of politicians such as Donald Trump.An essential read for students and scholars of political psychology and party politics, this book invites the reader to reconsider their perspectives on public opinion and partisan conflict.

Predisposed: Liberals, Conservatives, and the Biology of Political Differences

by Kevin B. Smith John R. Alford John R. Hibbing

Buried in many people and operating largely outside the realm of conscious thought are forces inclining us toward liberal or conservative political convictions. Our biology predisposes us to see and understand the world in different ways, not always reason and the careful consideration of facts. These predispositions are in turn responsible for a significant portion of the political and ideological conflict that marks human history. With verve and wit, renowned social scientists John Hibbing, Kevin Smith, and John Alford—pioneers in the field of biopolitics—present overwhelming evidence that people differ politically not just because they grew up in different cultures or were presented with different information. Despite the oft-heard longing for consensus, unity, and peace, the universal rift between conservatives and liberals endures because people have diverse psychological, physiological, and genetic traits. These biological differences influence much of what makes people who they are, including their orientations to politics. Political disputes typically spring from the assumption that those who do not agree with us are shallow, misguided, uninformed, and ignorant. Predisposed suggests instead that political opponents simply experience, process, and respond to the world differently. It follows, then, that the key to getting along politically is not the ability of one side to persuade the other side to see the error of its ways but rather the ability of each side to see that the other is different, not just politically, but physically. Predisposed will change the way you think about politics and partisan conflict. As a bonus, the book includes a "Left/Right 20 Questions" game to test whether your predispositions lean liberal or conservative.

Prefoldins: the new chaperones (Advances in Experimental Medicine and Biology #1106)

by Nabil Djouder

This book reviews recent work on molecular chaperones of the prefoldin family from their discovery in Archaea to the basic clarification of their structure. Even though, there is still a lot to investigate in order to understand the roles and functions of prefoldins, some preliminary work suggests their contribution in assembly and activation of a variety of macromolecular complexes. Hence, the reader is introduced to recent structural findings via cryo-electron microscopy and to the importance of this particular group of proteins in health and disease. This book also discusses the particular structure of the URI prefoldin-like complex. In addition, recent developments in the generation of URI mouse models speculate on the functions and emerging roles of the URI prefoldin-like complex in various cellular processes. This novel protein complex represents a unique cellular machinery, which molecular basis of its activity still remains to be determined.This work is thus a guide to help researchers in the field to have a more comprehensive and critical view of the prefoldin world.

Pregnancy and Postpartum Considerations for the Veterinary Team

by Emily Singler

Precautions often apply to pregnancy in any workplace, but being a vet in practice presents additional specific risks. There are concerns and uncertainty about potential hazards, from radiation and inhalant anesthesia exposure, to zoonoses, and the additional mental stress in a profession that already carries high suicide risk. This book reviews considerations for professionals in clinical veterinary medicine (large and small animal) while pregnant and after giving birth. Veterinarian and veterinary writer, consultant, and mentor Dr Emily Singler speaks directly to veterinary team members (veterinarians, technicians, CSRs, assistants, students) who are pregnant or plan to become pregnant. She delivers scientific information on the specific risks to the mother and baby that may be encountered during pregnancy while working in veterinary medicine, with some of her own and others’ experiences to add perspective and humor. The book also covers topics related to mental health challenges, announcing a pregnancy and planning for parental leave, navigating the fourth trimester, and returning to work. We hope that having read this book, veterinary professionals – whether pregnant or working with pregnant colleagues – will feel better supported and empowered to make informed decisions.

Prehension: The Hand and the Emergence of Humanity

by Colin Mcginn

This book is a hymn to the hand. In Prehension, Colin McGinn links questions from science to philosophical concerns to consider something that we take for granted: the importance of the hand in everything we do. <P><P>Drawing on evolutionary biology, anatomy, archaeology, linguistics, psychology, and philosophy, among other disciplines, McGinn examines the role of the hand in shaping human evolution. He finds that the development of our capacity to grasp, to grip, to take hold (also known as prehension) is crucial in the emergence of Homo sapiens. The human species possesses language, rational thought, culture, and a specific affective capacity; but there was a time when our ancestors had none of these. How did we become what we so distinctively are, given our early origins? McGinn, following Darwin and others, calls the hand the source of our biological success. When our remote ancestors descended from trees, they adopted a bipedal gait that left the hands free for other work; they began to make tools, which led to social cooperation and increased brain capacity. But McGinn goes further than others in arguing for the importance of the hand; he speculates that the hand played a major role in the development of language, and presents a theory of primitive reference as an outgrowth of prehension. McGinn sings the praises of the hand, and evolution, in a philosophical key. He mixes biology, anthropology, analytical philosophy, existential philosophy, sheer speculation, and utter amazement to celebrate humans' achievement of humanity.

Prehistoric America: An Ecological Perspective

by Betty Meggers

During the past 30 years, the relationship between humans and the environment has changed more drastically than during any previous period in human history. Local sustainable exploitation of natural resources has been overridden by global interests indifferent to the detrimental impact of their activities on local environments and their inhabitants. Increasingly efficient technology has reduced the need for human labor, but improved medical treatment favors reproduction and survival, creating a growing imbalance between population density and food supply. Rapid transportation is introducing alien species to distant terrestrial and aquatic environments, where they displace critical elements in the local food chain.This succinct and profusely illustrated volume applies evolutionary and cultural theory to the interpretation of prehistoric cultural development in the western hemisphere. After reviewing cultural development in Mesoamerica and the central Andes, Meggers examines adaptation in North and South American regions with similar environments to evaluate the influence of adaptive constraints on cultural content.What made the human species dominant on the planet is the substitution of cultural behavior for biological behavior. Prehistoric Americans applied this ability to develop sustainable relationships with their environments. Many succeeded and others did not. Paleoclimatic reconstructions can be compared with archeological sequences and ethnographic descriptions to identify cultural behavior responsible for the difference. Comparison of the responses of Amazonians and Mayans to episodes of severe drought provides useful insights into what we are doing wrong.
