Methods in Gut microbial ecology for ruminants
As a result of various human activities, such as increase in human population,decrease in arable land due to soil degradation, urbanization, industrialization and associated increase in the demand for livestock products, dramatic changes are occurring in the global ruminant livestock sector. These changes includeshift inthesize of regional livestock populations and in the types of management and feeding systems under which ruminant livestock are held, and increased demand of a wider range of quality attributes from animal agriculture, not just of the products themselves but also of the methods used in their production. The livestock sector will need to respond to new challenges of increasing live stock productivity while protecting environment and human health and conservingbiodiversity and natural resources. The micro-organisms in the digestive tracts of ruminant livestock have a profound in?uence on the conversion offeedinto end products, which can impact on the- imal and theenvironment. As the livestock sector grows particularly in developing countries, there will be an increasing need to understand these processes for b- ter management and use ofbothfeed and other natural resources that underpinthe development of sustainable feeding systems.

Medicina fisica e riabilitativa nei disturbi di equilibrio = Physical and rehabilitative medicine in balance disorders
Balance disorders are very common in the population: particularly frequent over the age of 40, are the first motivation for a medical examination after the age of 65 and frequently tend to become chronic. Balance disorders are symptoms of system dysfunction vestibular, complex sensory-psycho-motor system, whose task is that to control the activity of the antigravity muscles to maintain the erect station, of the oculomotor ones to allow the stabilization of the visual field during movement, and the neurovegetative functions they have relationship with standing and movement. Whether the vestibular system provides the information necessary for the check-up of the erect position, the rachis realizes it through a "stability dynamic ", allowed by its structural characteristics proprioception the spine is also a fundamental sensor for controlling balance ; therefore the techniques of physical and rehabilitative medicine and of manual medicine represent a powerful tool for curing ailments equilibrium. This volume comes from the comparison between a physiatrist and an audiologist, who for 15 years have integrated their clinical experience and therefore proposes a new one inter-specialist approach to the diagnostic and therapeutic problems of patients with balance disorders.
Measuring Methane Production from Ruminants
The world’s livestock sector is amidst a major transformation, fuelled by high demand for meat and milk, which is likely to double over the next two decades in developing countries. The challenge is to enhance animal productivity without adversely affecting the environment. A key to this is reducing methane emissions from ruminants. The major limitation to ruminant production in many tropical regions of Africa, Asia and Latin America, where a large proportion of the global ruminant population is located, is poor nutrition. The productivity of animals is restricted by the low nitrogen and high fibre content of the native grasses and crop residues, which form the basis of the diets in these regions. Animals on these types of diets emit more methane than animals fed better quality temperate forages. These methane emissions represent a loss of digestible energy to the animal (up to 15%) as well as a threat to the environment.The challenge is to devise nutritional strategies and identify dietary components, particularly from locally available plant resources, that reduce methane emissions.

Introduction to Computational Biology : An Evolutionary Approach
Molecular biology has changed dramatically over the past two decades. Until the early 1990s genes were studied one at a time by small teams of researchers; today entire genomes are sequenced by internationally collaborating laboratories. In the bygone gene-centered era the accumulation of data was the rate-limiting step in research. Now that step is often data interpretation. This is increasingly dependent on computational methods and as a consequence, computational biology has emerged in the past decade as a new subdiscipline of biology. This introduction to computational biology is centered on the analysis of molecular sequence data. There are two closely connected aspects to biological sequences: (i) their relative position in the space of all other sequences, and (ii) their movement through this sequence space in evolutionary time. Accordingly, the first part of the book deals with classical methods of sequence analysis: pairwise alignment, exact string matching, multiple alignment, and hidden Markov models. In the second part evolutionary time takes center stage and phylogenetic reconstruction, the analysis of sequence variation, and the dynamics of genes in populations are explained in detail. In addition, the book contains a computer program with a graphical user interface that allows the reader to experiment with a number of key concepts developed by the authors.
Intraspecific Genetic Diversity : Monitoring, Conservation, and Management
Population and evolutionary genetics have been quickly developing ?elds of biological research over the past decades. This book compiles our current understanding of genetic processes in natural populations. In addition, the book provides the author’s original ideas and concepts based on the data obtained by himself and his close coworkers. The author introduces his pioneering concept of population genetic stability,and much of thebook is concerned with the factors and conditions of such stability. Why does genetic stability matter so much? Altukhov argues that the sustainable use of natural resources, including genetic resources of popu- tions, critically depends on the maintenance of their stability. The preser- tion of well-adapted genetic characteristics from one generation to the next is essential for this stability. Traditionally, population genetics has been - cusedonevolution andthe role of evolutionary factorsinshapinggenetic structures of populations. While the idea of a population as a dynamic unit of evolution has been widely accepted, the signi?cance of genetic stability and its implications for the long-term survival of populations and species have not been fully appreciated.
Interventions for Persisting Ductus Arteriosus in the Preterm Infant
Over the past few years a remarkably rapid evolution in the professional level of neonatology and in the survival of immature infants has been witnessed. Persisting ductus arteriosus is common in this population and is associated with impaired longterm outcome. Many uncertainties exist concerning indication, approach, best time, and side effects of necessary measurements and interventions to avoid later neurodevelopmental handicaps of the survivors. Experts in neonatology and pediatric cardiology give their opinion in this book. We are sure it will help to define the level of evidence and to develop standards of intervention for persisting ductus arteriosus in Europe. Adequate dealing with the ductus will become a challenge for every perinatal center.

This volume offers an essential resource for economic policy makers and students of development economics to understand the interrelationships between internal migration, urbanization, and poverty in Asia, paving the way for the improved management of internal migration, and disadvantaged and vulnerable populations.
Internal fixation of femoral neck fractures : An Atlas
Femoral neck fractures occur primarily in the elderly population, and nowadays arthroplasty is chosen most frequently as a treatment solution. In the era of financial restrictions in health care system non-invasive internal fixation is an attractive choice, because in addition to the lower immediate costs the rehabilitation period might also be shorter. In this illustrated atlas the authors deal with epidemiological aspects, anatomical and biomechanical specialities of the given region, diagnostic and management potentials, satisfactory both for orthopaedic and trauma specialists. By means of presenting minimally invasive technique step-by-step, and their own results, the aim is to persuade the reader that the ratio of complications remarkably can be diminished by urgent surgery, based on selective indication criteria. Aspects of postoperative treatment and rehabilitation are also clarified in details.

Integrated Urban Water Resources Management
Growing populations and rising standards of living exert stress on water supply and the quality of drinking water. In wastewater management, new challenges are caused by new chemicals of concern, including endocrine disrupters, pharmaceuticals, hormones, and personal care products, which often pass through wastewater treatment plants unabated, but may cause serious impacts on receiving aquatic ecosystems. Advanced wastewater treatment leads to production of biosolids, which are processed in various ways, including on-land applications in agriculture. Municipal effluents, combined with increasing withdrawals of water, lead to the worsening of receiving water quality. Expert opinions indicate that the only way to deal with the current urban water management dilemmas is by integrated management and innovative delivery of water services. This book presents important aspects of Challenges in Management of Urban Water Resources, Challenges in Urban Water Supply, Urban Drainage and Water Bodies, Wastewater Treatment and Security, and Wastewater Treatment and Reuse.
