Hemostasis Management of the Pediatric Surgical Patient provides knowledge on the emerging area of pediatric hemostasis and its management. It discusses aspects of perioperative blood management in the pediatric population, including how to accurately estimate and monitor bleeding and determine optimal treatment regimens for bleeding in pediatric surgical patients. It also provides information on the implementation of intraoperative blood conservation strategies, goal-directed transfusion therapy, and postoperative estimation of bleeding and thrombotic risks. This book is a valuable resource to pediatric practitioners and researchers who need comprehensive information on pediatric hematology, from basic physiology to pre-, intra- and postoperative care of pediatric patients. The coagulation system of children evolves with age as evidenced by marked physiological differences in the concentration of hemostatic proteins between children of different age groups and adults. Consequently, there are distinct differences in hemostatic management between adult and pediatric patients.
Since its commercial introduction in 2004, UHPLC (Ultra-High Performance Liquid Chromatography) has begun to replace conventional HPLC in academia and industry and interest in this technique continues to grow. Both the increases in speed and resolution make this an attractive method; particularly to the life sciences and more than 1500 papers have been written on this strongly-evolving topic to date. This book provides a solid background on how to work with UHPLC and its application to the life sciences. The first part of the book covers the basics of this approach and the specifics of a UHPLC system, providing the reader with a solid background to working properly with such a system. The second part examines the application of UHPLC to the life sciences, with a focus on drug analysis strategies. UHPLC-MS, a key technique in pharmaceutical and toxicological analyses, is also examined in detail. The editors (Davy Guillarme and Jean-Luc Veuthey) were some of the earliest adopters of UHPLC and have published and lectured extensively on this topic. Between them they have brought together an excellent team of contributors from Europe and the United States, presenting a wealth of expertise and knowledge. This book is an essential handbook for anyone wishing to adopt an UHPLC system in either an academic or industrial setting and will benefit postgraduate students and experienced workers alike.
Migrations and population dynamics are considered very problematic topics in the fields of ancient studies. Recent scholarship in (pre)historical population has generated new impulses by using scientific approaches using radiogenic and stable isotopes, and palaeogenetics, as well as computer simulation. As a result, the state of migration research has undergone rapid change. Several research groups presented papers at aconference held in Berlin in 2010, addressing specific historical aspects of population dynamics and migration, with no chronological or geographical restrictions, in the light of cutting-edge bio-archaeological research. This volume, divided into three larger thematic sections (isotope analysis, population genetics, and modelling and computer simulation), presents experiences and insights about methodological approaches, research results and prospects for future research in this area in a varied collection of papers. Scholars from widely diverse scientific disciplines present their approaches, findings and interpretations to an audience far broader than the circles of the individual disciplines.

The NATO Advanced Research Workshop (ARW) on "Regulation of Enzymatic Systems Detoxifying Xenobiotics in Plants" intended to provide a forum to scientists from academia, industry, and govemment for discussing and critically assessing recent advances in the field of xenobiotic metabolism in plants and for identifying new directions for future research. Plants function in a chemical environment made up of nutrients and xenobiotics. Xenobiotics (foreign chemicals) are natural or synthetic compounds that can not be utilized by plants for energy-yielding metabolism. Plants may be exposed to xenobiotics either deliberately, due to their use as pesticides or accidentally, from industrial, agricultural, and other uses. Plants, like most other organisms, evolved a remarkable battery or metabolic reactions to defend themselves against the potentially toxic effects of xenobiotics. The main enzymatic reactions utilized by plants for xenobiotic detoxification include oxidation, reduction, hydrolysis and conjugation with glutathione, sugars (e.g., glucose), and amino acids. Eventually, xenobiotic conjugates are converted to insoluble bound residues or to secondary conjugates, which are deposited in the vacuole of plant cells.
During the last 40 years, the study of the biological basis of
aging has progressed tremendously, and it has now become an
independent and respectable field of study and research. The
essential cause of aging is molecular damage that slowly overwhelms
cellular and organismic defense, repair and maintenance systems. In
recent years, a wealth of highly sophisticated research has
transformed this idea from a credible hypothesis not only to a
major theory, but essentially to accepted knowledge. Aging at the
Molecular Level examines the key elements in this transformation.

This book investigates in detail the emerging deep learning (DL) technique in computational physics, assessing its promising potential to substitute conventional numerical solvers for calculating the fields in real-time. After good training, the proposed architecture can resolve both the forward computing and the inverse retrieve problems. Pursuing a holistic perspective, the book includes the following areas. The first chapter discusses the basic DL frameworks. Then, the steady heat conduction problem is solved by the classical U-net in Chapter 2, involving both the passive and active cases. Afterwards, the sophisticated heat flux on a curved surface is reconstructed by the presented Conv-LSTM, exhibiting high accuracy and efficiency. Besides, the electromagnetic parameters of complex medium such as the permittivity and conductivity are retrieved by a cascaded framework in Chapter 4. Additionally, a physics-informed DL structure along with a nonlinear mapping module are employed to obtain the space/temperature/time-related thermal conductivity via the transient temperature in Chapter 5. Finally, in Chapter 6, a series of the latest advanced frameworks and the corresponding physics applications are introduced. As deep learning techniques are experiencing vigorous development in computational physics, more people desire related reading materials. This book is intended for graduate students, professional practitioners, and researchers who are interested in DL for computational physics.
Now and in the future, the ever-growing demand for drinking water will lead many cities to implement indirect water reuse programs, where wastewater effluent becomes part of the drinking water sources. Pollution of those sources with emerging contaminants (micropollutants) such as endocrine disrupting compounds, pharmaceutically active compounds, pesticides and personal care products is a fact known worldwide. In this thesis, nanofiltration (NF) and reverse osmosis (RO) are demonstrated to be appropriate technologies for removing a large number of micropollutants; however, the performance of NF and RO can be questioned because there are limited tools that optimise quantification of the removal of contaminants. Therefore, in this thesis, by means of the use of multivariate data analysis techniques, removal quantification is effectively determined and more understanding of the separation of micropollutants by membranes is achieved.
Life in Space explores the many aspects and outcomes of NASA's research in life sciences, a little-understood endeavor that has often been overlooked in histories of the space agency. Maura Mackowski details NASA's work in this field from spectacular promises made during the Reagan era to the major new directions set by George W. Bush's Vision for Space Exploration in the early twenty-first century. At the first flight of NASA's space shuttle in 1981, hopes ran high for the shuttle program to achieve its potential of regularly transporting humans, cargo, and scientific experiments between Earth and the International Space Station. Mackowski describes different programs, projects, and policies initiated across NASA centers and headquarters in the following decades to advance research into human safety and habitation, plant and animal biology, and commercial biomaterials. Mackowski illuminates these ventures in fascinating detail by drawing on rare archival sources, oral histories, interviews, and site visits. While highlighting significant achievements and innovations such as space radiation research and the Neurolab Spacelab Mission, Mackowski reveals frustrations-lost opportunities, stagnation, and dead ends-stemming from frequent changes in presidential administrations and policies. For today's dreams of lunar outposts or long-term spaceflight to become reality, Mackowski argues, a robust program in space life sciences is essential, and the history in this book offers lessons to help prevent leaving more expectations unfulfilled.

The COVID-19 Pandemic: A Global High-Tech Challenge at the Interface of Science, Politics, and Illusions discusses COVID-19 as the first pandemic in the Internet era and our current reality of continuous reports, news, and updates. Since its beginning, we were daily bombarded with news of what was happening around the world. There was no global political leadership. The United States was politically partially paralyzed. Russia and China hoped to gain diplomatic profile worldwide, but their vaccines are of limited efficacy, and trust in their clinical data is rightly low. The European Union did not order enough vaccines in time, but sued a large manufacturer for delivery delays. Now it is setting up yet another bureaucratic institution. At least the pharmaceutical or life science industry paved the way out, but is not enthusiastically praised for it. It would be too easy and superficial to blame mistakes of governments and leaders on stupidity. Idiocy exists, but we have to go deeper to understand how illusions and blind spots in today's common perception and science, inertia, arrogance, conflicts of interest, competition of individuals, and states and institutions for public recognition have contributed to a multitude of flawed assessments and direct mistakes. Healthcare professionals and anyone interested in an in-depth understanding of humankind's response to the COVID-19 challenge will not get around the key conclusions of this book.
Clinical Decision Support and Beyond: Progress and Opportunities in Knowledge-Enhanced Health and Healthcare, now in its third edition, discusses the underpinnings of effective, reliable, and easy-to-use clinical decision support systems at the point of care as a productive way of managing the flood of data, knowledge, and misinformation when providing patient care. Incorporating CDS into electronic health record systems has been underway for decades; however its complexities, costs, and user resistance have lagged its potential. Thus it is of utmost importance to understand the process in detail, to take full advantage of its capabilities. The book expands and updates the content of the previous edition, and discusses topics such as integration of CDS into workflow, context-driven anticipation of needs for CDS, new forms of CDS derived from data analytics, precision medicine, population health, integration of personal monitoring, and patient-facing CDS. In addition, it discusses population health management, public health CDS and CDS to help reduce health disparities. It is a valuable resource for clinicians, practitioners, students and members of medical and biomedical fields who are interested to learn more about the potential of clinical decision support to improve health and wellness and the quality of health care.
Whole new areas of immunological research are emerging from the analysis of experimental data, going beyond statistics and parameter estimation into what an applied mathematician would recognise as modelling of dynamical systems. Stochastic methods are increasingly important, because stochastic models are closer to the Brownian reality of the cellular and sub-cellular world.
