Lactic acid bacteria : Methods and protocols
This updated volume presents experimentation-based approaches to lactic acid bacteria (LAB) research. Split into three parts, the book explores techniques for analyzing lactic acid bacteria metabolism and characteristics, applications for food-related industries, such as yogurt production, beer, and wine making, and functions of LAB in human health. Written for the highly successful Methods in Molecular Biology series, chapters include introduction to their respective topic, lists of the necessary materials and reagents, step-by-step and readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
Biogeography and Ecology of Bulgaria
The book includes 22 chapters by 28 authors united by the single theme: biogeography and ecology of Bulgaria. From the single-celled organisms in the Black Sea sand to the endemic cave crustaceans, from the mountain glacial relict insects to the most diverse bird fauna in Europe, the unique fauna of Bulgaria has been a subject of study of mostly Bulgarian zoologists for more than a century. This is the first monograph in English broadly addressing all vertebrate and many key invertebrate groups of Bulgaria, their faunistics, origin, geographical and ecological distribution, and conservation issues are addressed by the experts on each group.
Biodiversity of angola : Science & conservation : A modern synthesis
The book identifies Angola as one of the most biologically diverse countries in Africa, but notes that its fauna, flora, habitats and the processes that drive the dynamics of its ecosystems.
Biodiversity and Conservation in Europe
This book brings together a selection of original studies submitted to Biodiversity and Conservation that address biodiversity and conservation in Europe. Europe is certainly the most intensively inventoried region of the world; detailed maps are available for species distributions while action plans are being drawn up for species under threat. At the same time, the wildlife of Europe has been subject to enormous human pressures, with limited ‘wilderness’ sites remaining in most countries. Europe consequently presents a case-study of what the human impact on biodiversity has been, and also what can be done to improve the situation.
Bill Ricker : An appreciation
This book is the first complete biography of one of the founders of fishery science, William Edwin (Bill) Ricker (1908 - 2001). Bill is immortalized in the Ricker Curve. He developed the Curve in his studies of stock and recruitment in fisheries, but it has been widely applied in many areas of science. Bill is best known for his contributions to fishery science, but he was also internationally recognized as an entomologist and a scientific editor. This book combines Bill’s own recollections with contributions from those who knew him and worked with him as a colleague during his multifaceted career. In an article written shortly before his death, Bill gives his own account of his career and intellectual development.
Arid Dune Ecosystems: The Nizzana Sands in the Negev Desert
Sand dune dynamics plays a key role in many arid deserts. This volume provides a synthesis of a specific sand dune ecosystem, the Nizzana site in the Negev Desert. Describing its climate and geophysical/geochemical properties of soils, geological history, flora and fauna, and past/present land-use patterns, it elucidates ecological and geomorphological processes and their interrelations, based on long-term monitoring, in situ experiments and satellite imagery. Particular attention is drawn to the impact of the topsoil biological crust in controlling water availability at local/regional scales. The interdisciplinary approach adopted in this case study offers a good example of a highly complex and dynamic system, which could easily be applied to other sandy ecosystems.
Composite and polymeric materials for dentistry: enhancing antimicrobial and mechanical properties
Focuses on enhancing antimicrobial and mechanical properties of polymeric materials and composites for dentistry. In recent years, special attention has been focused on the possibility of giving materials new or improved properties by the introduction of nano or submicron size additives, fibers or whiskers. Another area of research is the application of antibacterial monomers, which can be copolymerized in resins to kill oral pathogenic microflora. In addition, we are currently looking for new data regarding colonization of dental materials by pathogenic microbes and their influence on the other properties. Further, there are many new commercially available materials which should be investigated to verify their properties, which is important from the point of view of clinical practice. Original new research and reviews related to any of the topics mentioned above indicate the current directions of development of dental materials.
Manual for Soil Analysis - Monitoring and Assessing Soil Bioremediation
Reliable methods for monitoring and assessing soil quality are a prerequisite for successful soil bioremediation projects. The fifth volume of Soil Biology presents detailed descriptions of selected methods for evaluating, monitoring and assessing bioremediation treatments of soils contaminated with organic pollutants or heavy metals.
Lochnagar : The Natural History of a Mountain Lake
The remote mountain loch of Lochnagar is one of the most studied freshwater bodies in Europe. This book brings together knowledge gained over two decades of multi-disciplinary scientific study, with the results of lake sediment research covering millennia, to show how the loch has developed both naturally and as a result of human impact
CCD Image Sensors in Deep-Ultraviolet : Degradation Behavior and Damage Mechanisms
As the deep-ultraviolet (DUV) laser technology continues to mature, an increasing number of industrial and manufacturing applications are emerging. For example, the new generation of semiconductor inspection systems is being pushed to image at increasingly shorter DUV wavelengths to facilitate inspection of deep sub-micron features in integrated circuits. DUV-sensitive charge-coupled device (CCD) cameras are in demand for these applications. Although CCD cameras that are responsive at DUV wavelengths are now available, their long-term stability is still a major concern. This book describes the degradation mechanisms and long-term performance of CCDs in the DUV, along with new results of device performance at these wavelengths.
Biological processes associated with impact events
The biological effects of asteroid and comet impacts have been widely viewed as primarily destructive. The role of an impactor in the K/T boundary extinctions has had a particularly important influence on thinking concerning the role of impacts in ecological and biological changes. th During the 10 and final workshop of the ESF IMPACT program during March 2003, we sought to investigate the wider aspects of the involvement of impact events in biological processes, including the beneficial role of these events from the prebiotic through to the ecosystem level. The ESF IMPACT programme (1998-2003) was an interdisciplinary effort that is aimed at understanding impact processes and their effects on the Earth environment, including environmental, geological and biological changes.
Bioactive components of milk
Of all food products dairy foods have the most potential concerning functional foods. Therefore, there is a tremendous amount of interest in value-added milk products and the identification of components in food which have health benefits. Bioactive Components of Milk provides an overview of these derived components and their diverse activities including: the stimulation of beneficial microflora, alerting the immune system to the presence of potential pathogens and allergens, binding and eliminating toxins, etc. The book is divided into four parts. The first part focuses on bioactive milk lipid components, which very widely among mammalian species. The second part describes different aspects of biological active colostrums and milk proteins and their derivatives, with special concern on species specific effects. The third part reviews the production of recombinant human proteins in the milk of livestock animals - including ethical issues - and the aims of altering milk composition for the benefit of both the animals themselves and the consumers. The final part focuses on the influence of ruminants nutrition on the biological activity of milk.
