Buch. Zustand: Neu. Neuware - This century has been called 'the information age and information is regarded as a symbol of progress, the dynamic development of a society. It has become a major component of a growing number of products; it is gradually turning into an independent product and more confidently crowding out other products and services, gaining a leading position on them. Every year, many people in the information field engage in the collection, processing, transfer and storage of information, and the production of hardware and software required for the smooth operation of information systems. Politicians, economists and sociologists confidently use the phrase 'information rich' and 'information poor.' These terms are used characterize not only individuals and social groups, but also entire countries. The well-being of citizens and peoples, along with the presence of wealth in recent years has been increasingly determined access to information resources.The explosive growth of information flow and related technologies has led to a global change in the communication system. Its appearance, along with the traditional series of new social institutions, has involved meeting the specific information needs of society; however, this includes the more rapidly growing amount of information and with it the social costs of its handling and transportation. More relevant is the question of determining the nature of institutions, ensuring its functioning in society.The library is one of the oldest public institutions, aimed at meeting the information needs of society. At different stages of history, the understanding of the library's social status has changed its role and importance in public life. However, the main influence on the development of libraries provided the information needs of users, structure document-flow of any age, political, socio-cultural, economic and technological features of the development of society. The present stage of human history is characterized by globalization, information and democratization of all spheres of public life. The new type of society has ensured the rapid development of electronic technology, along with the collection, processing, storage and use of various types of information, and access of representatives of different social groups to national and global information resources. That is, these resources define the intellectual, economic, political and even military power of the state.These factors contribute to the resumption of the debate on the place and role of libraries in modern society and the prospects for their development. The progress of computer technology and information technology has led to the emergence of theories predicting their functions and restrictions, turning them into institutions designed to meet the needs of only the disadvantaged sections of society. Even their gradual extinctions and increasingly discussed question concerning the role of libraries in providing information freedom and security of citizens, thus revealing the essence of the library as a modern social institution. The definition of the principles of its activities and functions of the interaction between the external and internal environment, problems and prospects of development are important and relevant today.The emergence and development of libraries has always been associated with the need to transfer accumulated information from individual to individual, from generation to generation. For thousands of years, the library was needed for the development of science, education, culture, industry and agriculture. Thanks to libraries, we have kept many priceless treasures of human thought throughout the history of civilization. Accumulating the wisdom of the ages, libraries contribute to the preservation, development, and growth of knowledge. Despite the fact of the library as a phenomenon, throughout several thousands of years of study of its essence, specialists have paid insufficient attention. This is largel.

Buch. Zustand: Neu. Neuware - Dairy farming is one of the fastest growing and developing subsectors in the agricultural industry. There has been unprecedented growth in milk production attributed by proper genetic selection, breeding, housing, and feeding programs in this subsector. Dairy farming for milk production has been the primary business for many people in different places around the world. Milk has also been and still is a key animal product in most diets consumed worldwide. With various advancements achieved in preservation of techniques for dairy products, preference of consumers for milk and milk products are higher than ever. Basic information on the technology and science used in production and processing this crucial food commodity is significant to the work of academia, governments, and industry.Several good and professionally prepared reference books are available, but the preference for any specific book greatly depends on the needs for the reader. Most of the dairy farming reference books are single-volume books, and others only cover general topics whereas other books cover specific dairy farming topics. This book has been prepared to offer essential information about basic principles involved in milk production, nutritional requirement for dairy cattle, basic management practices involved in dairy farming and health conditions that affect dairy cows in milk production to all those student taking dairy farming management courses, veterinary professionals, teachers, dairy management staffs, and even various governmental staffs involved in agricultural sectors. The general science and various production practices presently in use in dairy industry have been characterised and well described so that the reader can acquire insights into the industry. The book has been divided into four sections. Section one deal with general information and principles on dairy farming and it consist of only one chapter. Section two deals with background information on nutrition requirements in milk production and consists of four chapters. Section three deals with general management practices involved in dairy farming for maximum milk production and consist of four chapters. Lastly, section four dealing with dairy farming health problems consists of one chapter. More emphases have been put in nutrition and management practices of dairy cow because these are the two key areas where most breeders and producer focus on in order to enhance milk production. Specific areas tailored towards minimizing production costs and maximizing overall production have also received much of the attention, specifically on the second, third and fourth section of the book.

Buch. Zustand: Neu. Neuware - Poultry is one of the fastest growing and developing subsectors in agricultural industry. There has been unprecedented growth in production of poultry meat and egg attributed by proper genetic selection, breeding, housing, and feeding programs in this subsector. Poultry rearing for egg and meat production has been the primary business for many people in different places around the world. Poultry has also been and still is a key animal product in most diets consumed worldwide. With various advancements achieved in preservation of techniques for poultry products and processed products, preference of consumers for poultry and poultry products are higher than ever. Basic information on the technology and science used in production and processing this crucial food commodity is significant to the work of academia, governments, and industry.Several good and professionally prepared reference books are available, but the preference for any specific book greatly depends on the needs for the reader. Most of the poultry reference books are single-volume books, and some books only cover general topics, whereas others cover specific poultry topics. This book has been prepared to provide essential information about poultry anatomy, breeding and genetics to all those student taking poultry management courses, veterinary professionals, teachers, poultry management staffs, and even various governmental staffs involved in agricultural sectors. The general science and various production practices presently in use in poultry industry have been characterised and well described so that the reader can acquire insights into the industry.

Lastly, section four dealing with poultry genetics consists of three chapters.In order to perform post-mortem on poultry and be able to evaluate various internal and external diseases of poultry that influence viability of a breeding program, students should understand the key anatomic components of poultry. This book is essential because it has relevant information on various anatomic systems of a bird-both internal and external (second section). It has also elaborated in details about various genetic principles and how they influence poultry breeding and production practices. More emphases have been put in breeding and production of meat type chickens and egg producing poultry birds because these are the two key areas where most breeders and producer focus on. Specific areas tailored towards minimizing production costs while maximizing overall production have also received much of the attention, specifically on the third and fourth section of the book (poultry breeding and genetics).

Buch. Zustand: Neu. Neuware - With the world population growth, food demand grows. Aquatic foods provide high quality protein, essential for human health. It is clearly visible that the production of aquatic organisms using aquaculture will have to increase, to the extent that the fishery productivity holds steady over the past few years, even increasing fishing effort. The total production of aquatic organisms by-catch (including fish, molluscs, crustaceans, etc.) represents 83.5 million tonnes in the year 2014, with a stable production for some years. On the other hand, aquaculture has grown enough in recent years. In the year 2006 the total output of aquatic organisms through cultivation was approximately 45 million tonnes in 2014 the production over 73 million tones. Since the establishment and technical domain about reproduction and hatchery of marine fish, has begun a process of genetic improvement, as the best individuals were selected for mating and reproduction in search of the best possible offspring. According to Dunham et al. (2000), breeding programs began in the 1960s. Molecular-based knowledge emerged in the 1980s and has continued to gain momentum. Efforts are now well established in traditional selective breeding, biotechnology and molecular genetics of finfish, and are rapidly developing for aquatic invertebrate domestication.Genetic improvement is the theory that aims to find the animals that produce the best offspring generation after generation, increasing the population average to some trait. The main objectives of the breeding programs are: increase animal health and increase productivity and product quality. However, on aquaculture, breeding programs are not common, and in many species the production is based only on the capture of wild animals. This can be explained, primarily because of the complexity of the reproductive cycle; the rapid increase of inbreeding in breeding stocks; and the few knowledge of the theory of genetic improvement for researchers, educators, etc. In addition to all this, the breeding programs of aquatic organisms face severe problems compared to terrestrial animals. The genetic improvement for aquatic organisms really is a challenging path ahead of us, for that we shall seek to carry out research to help this area to develop, benefiting the entire aquaculture chain.

Buch. Zustand: Neu. Neuware - Billions of spots of tiny genetic code comprise the human genome. It was DNA sequencing technology that had revolutionized genomic research by decoding the valuable genetic information by giving the picture of an exact order of occurrence of nucleotides in a DNA. The inception of first-generation sequencing method, also called Sanger sequencing took place in 1975. The first major breakthrough of first-generation sequencing comes, when the 13 year log Human Genome Project (HGP) was completed in 2003 at a cost $3 million. With ever increasing demands of researchers and clinicians, complex genomic research require a depth of information which is however beyond the capacity of traditional DNA sequencing technologies. These research questions gaps are very well addressed by Next-generation sequencing (NGS) has filled that gap of cheaper as well as faster sequencing technology. It is just a decade old technology, but it has popularize the next-generation sequencing to high-throughput sequencing hat allow millions to trillions of observations to be made in parallel during a single instrument run. Since the introduction of these technologies, the number of applications and methods that influence the power of genome-scale sequencing has increased exponentially. Although in genome research NGS has mostly superseded conventional Sanger sequencing, it has not yet translated into routine clinical practice. The following chapter will highlight the concepts, technologies, and methods of next-generation sequencing to illustrate the breadth and depth of the applications and research areas that are driving progress in genomics.

Buch. Zustand: Neu. Neuware - The seaweeds are a large group of marine macroalgae that can be found in several coastal regions around the world. Though there are about 9200 species of seaweeds, only 221 species are economically important (Mohammed, 2013). There are three different groups of seaweed--red, brown, and green their characteristic colors and properties. Seaweed cultivation is a relatively old and extremely important activity for the human being, because of the various properties and utilities that it owns. There are records of use of this feature in the 4th century in Japan and in the 6th century in China. Both countries along with the Republic of Korea are the biggest consumers of seaweed in the world, contributed with 80% of global production (Mohammed, 2013). Worldwide, the most extensive crops are performed in the open sea or estuaries, with little technology involved and in order to help in the income of the fishermen. However, in this system the biggest concern and effort involved is in management, mainly of the harvest, but also daily by the need of monitoring the situation and existing dynamics in these regions. Seaweeds have various uses and great commercial importance on the world market. Among them, we highlight the production of hydrocolloids (agar, carrageenans, and alginate), fertilizers, nutraceuticals, human food, water treatment, bioremediation, biofuels, medicinal uses, for spa and beauty, among others. The worldwide seaweed industry provides a wide variety of products for direct or indirect human uses that have an estimated total value of US$10 billion per year (Bixler & Porse 2011). Since the emergence of the seaweed cultivation processes are in constant improvement, mainly related to knowledge, management and improvements within the activity. Naturally, the demand for seaweed products has generated the need for increased knowledge to resolve main problems in the development of seaweed aquaculture, as for example the selection of suitable environments; engineering of the seashore for farming; protection of crops from pests and physical or biotic impacts; and proper transplantation and harvesting procedures (Buschmann et al., 1995). Seaweeds are a highly renewable food resource. They can be grown and harvested all year round, in any marine environment. Production is low impact - seaweeds need no chemicals, fertilizers or pesticides, in addition to require no deforestation. Seaweed cultivation can still be added in different production systems as bioremediation and in treatment of effluents from industry, in order to contribute to the maintenance of the quality of the environment. In addition to bring benefits to the environment, the seaweed cultivation has contributed to increase income of the coastal communities that depend on fishing. Although the cultivation of seaweed being a relatively simple activity with respect to processes, many improvements can be made from the point of view of management and production, so as to make easiest and most effective methods. Therefore, it is essential to maintain the focus and work on research that seeks the development and evolution of the area. In addition to being an important economic resource, is fundamental basis for the conservation of marine and coastal ecosystems worldwide.
