Thermophiles: Biodiversity, Ecology, and Evolution

by RoccoMancinelli MaryVoytek Anna-LouiseReysenbach

These are indeed exciting times to be a microbiologist. With one of the buzzwords of the past decade-"Biodiversity," and microbes are reveling in the attention as they represent by far most of the biodiversity on Earth. Microbes can thrive in almost any environment where there is an exploitable energy source, and, as a result, the possible existence of microbial life elsewhere in the solar system has stimulated the imaginations of many. Extremophiles have taken center stage in these investigations, and thermophiles have taken on the lead roles. Consequently, in the past decade there has been a surge of interest and research in the Ecology, Biology, and Biotechnology of microorganisms from thermal environments. Many of the foundations of thermophile research were laid in Yellowstone National Park, primarily by the research of Professor Thomas Brock's laboratory in the late 1960s and early 1970s. The upper temperature for life was debated, the first thermophilic archeum discovered (although it was only later shown to be an archeum by ribosomal cataloging), and the extremes of light, temperature, pH on the physiology of microorga­ nisms were explored. Interest in thermophiles increased steadily in the 1970s, and with the discovery of deep-sea hydrothermal vents in 1977, thermophilic research began its expo­ nential explosion. The development of Taq polymerase in the polymerase chain reaction (peR) focused interest on the biotechnological potential of thermophilic microorganisms and on the thermal features in Yellowstone National Park.

Thermodynamics of Pharmaceutical Systems: An Introduction for Students of Pharmacy

by Kenneth A. Connors

Studies of thermodynamics often fail to demonstrate how the mathematical intricacies of the subject relate to practical laboratory applications. Thermodynamics of Pharmaceutical Systems makes these connections clear, emphasizing specific applications to pharmaceutical systems in a study created specifically for contemporary curriculums at colleges of pharmacy. Students investigating drug discovery, drug delivery, and drug action will benefit from Kenneth Connors's authoritative treatment of the fundamentals of thermodynamics as well as his attention to drug molecules and experimental considerations. An extensive appendix that reviews the mathematics needed to master the pharmacy curriculum proves an invaluable reference. Connors divides his one-of-a-kind text into three sections: Basic Thermodynamics, Thermodynamics of Physical Processes, and Thermodynamics of Chemical Processes; chapters include: * Energy and the First Law of Thermodynamics * The Entropy Concept * Phase Transformations * Solubility * Acid-Base Equilibria * Noncovalent Binding Equilibria Thermodynamics need not be a mystery nor be confined to the realm of mathematical theory. Thermodynamics of Pharmaceutical Systems introduces students of pharmacy to the profound thermodynamic applications in the laboratory while also serving as a handy resource for practicing researchers.

Thermodynamics and Biophysics of Biomedical Nanosystems: Applications and Practical Considerations (Series in BioEngineering)

by Costas Demetzos Natassa Pippa

This book highlights the recent advances of thermodynamics and biophysics in drug delivery nanosystems and in biomedical nanodevices. The up-to-date book provides an in-depth knowledge of bio-inspired nanotechnological systems for pharmaceutical applications. Biophysics and thermodynamics, supported by mathematics, are the locomotive by which the drug transportation and the targeting processes will be achieved under the light of the modern pharmacotherapy. They are considered as scientific tools that promote the understanding of physicochemical and thermotropic functionality and behavior of artificial cell membranes and structures like nanoparticulate systems. Therefore, this book focusses on new aspects of biophysics and thermodynamics as important elements for evaluating biomedical nanosystems, and it correlates their physicochemical, biophysical and thermodynamical behaviour with those of a living organism.In 2018, Prof. Demetzos was honored with an award by the Order of Sciences of the Academy of Athens for his scientific contribution in Pharmaceutical Nanotechnology.

Thermodynamic Network Analysis of Biological Systems (Universitext)

by J. Schnakenberg

This book is devoted to the question: What fundamental ideas and concepts can phys­ ics contribute to the analysis of complex systems like those in biology and ecolo­ gy? The book originated from two lectures which I gave during the winter term 1974/75 and the summer term 1976 at the Rheinisch-Westfalische Technische Hoch­ schule in Aachen. The wish for a lecture with this kind of subject was brought forward by students of physics as well as by those from other disciplines like biology, physiology, and engineering sciences. The students of physics were look­ ing for ways which might lead them from their monodisciplinary studies into the interdisciplinary field between physics and life sciences. The students from the other disciplines suspected that there might be helpful physical concepts and ideas for the analysis of complex systems they ought to become acquainted with. It is clear that a lecture or a book which tries to realize the expectations of both these groups will meet with difficulties arising from the different train­ ings and background knowledge of physicists and nonphysicists. For the physicists, I have tried to give a brief description of the biological aspect and significance of a problem wherever it seems necessary and appropriate and as far as a physicist like me feels authorized to do so.

Thermal Treatments of Canned Foods (SpringerBriefs in Molecular Science)

by Angela Montanari Caterina Barone Michele Barone Anna Santangelo

This Brief describes the chemical features of canned food products and gives background information on the technology of canning foods. It explains how canned foods are different from other packaged foods, and illustrates and discusses their unique properties, including risks and failures. Canned foods are usually considered to offer a particularly long shelf-life and durability. An understanding of their properties and influences on their durability is therefore of great importance in the industrial production, and this Brief offers a compact introduction to this topic.The authors focus on thermally-preserved foods. They explain that the right choice of thermal treatment method (e.g. pasteurisation, sterilisation) as well as process parameters (e.g. time, temperature) is additionally influenced by criteria such as pH, water content, the presence and concentration of fatty molecules, of calcium, etc. So-called ‘survival curves’ can help in determining the methodology of choice, and the Brief introduces the reader to this concept. The authors also address defects and failures. They introduce selected indicators, which can help identifying failures of the entire food/packaging system, and demonstrate how image and visual analysis can be applied in quality controls. The explanations and industrial production of canned foods are exemplified with the case of canned tomato sauces and beans.

Thermal Dosimetry and Treatment Planning (Clinical Thermology)

by John C. Chato Keith D. Paulsen Robert B. Roemer

When in the future improved and more flexible heating equipment becomes available, and when hyperthermia is applied more routinely, computerized simulations of treatments will become commonplace, as they are in radia­ tion therapy. For hyperthermia, however, such simulations will be used not only for the traditional role of planning patient treatment, but also for three other applications not needed in radiation therapy - the comparative evalu­ ation of equipment, feedback control during treatment, and the post-treat­ ment evaluation of therapy. The present simulations of hyperthermia are crude and simple when compared with what is required for these future ap­ plications, a fact which indicates the nedd for considerable research and de­ velopment in this area. Indeed, this research is proceeding rapidly within the hyperthermia community, whre three-dimensional power deposition and temperature calculations have just become available for realistic patief\t anatomies. Of equal significance are the even more rapid development in diagnostic imaging for the determination and display of patient anatomy and blood flow rates - information required for the planning of realistic hyperthermia treatment. These simulations will be very valuable tools which can be used to great ad­ vantage when combined with data obtained from treatments of patients.

by Magdalini Krokida

Encapsulation is a topic of interest across a wide range of scientific and industrial areas, from pharmaceutics to food and agriculture, for the protection and controlled release of various substances during transportation, storage, and consumption. Since encapsulated materials can be protected from external conditions, encapsulation enhances their stability and maintains their viability. This book offers a comprehensive review of conventional and modern methods for encapsulation. It covers various thermal and nonthermal encapsulation methods applied across a number of industries, including freeze drying, spray drying, spray chilling and spray cooling, electrospinning/electrospraying, osmotic dehydration, extrusion, air-suspension coating, pan coating, and vacuum drying. The book presents basic fundamentals, principles, and applications of each method, enabling the reader to gain extended knowledge. The choice of the most suitable encapsulation technique is based on the raw materials, the required size, and the desirable characteristics of the final products.

It is concise, clear and easy to use. Primary care professionals, including doctors, nurses and health visitors will find it invaluable, as will general practitioners in training. 'There is much more to these diseases than most of us realise. It will not take you long to find fascinating and useful material here. It makes for a very interesting read. The evidence about management, as well as diagnosis, is very important. Acute respiratory infection is one of the famously important areas in which mistaken beliefs by not only our patients, but also us doctors, of the benefits of antibiotics makes to the contribution of bacterial resistance. Graham Worrall has highlighted new forms of treatment we often forget when we reach for the pad to write another 'safety' prescription for antibiotic. There is a wealth of information here.' - Chris Del Mar, in his Foreword. 'An objective, thoughtful treatment of a subject that accounts for a large part of a primary care physician's working life but inexplicably little of his or her training. Thorough evaluation of the literature, often exposing huge gaps in the study of these extremely common conditions, will serve as an impetus for study and a guide to rational decision-making. The straightforward approach with excellent practical distillations of the evidence and resulting recommendations is perfect for the busy physician or busy student. As someone who teaches medical students about infections I have longed for a concise resource to support my efforts at encouraging prudent antibiotic prescription for respiratory tract infections. I long no more.' - James Hutchinson, in his Foreword.
