Free Download Bacterial Fish Pathogens: Disease of Farmed and Wild Fish By Brian Austin, Dawn A. Austin (auth.)
2012 | 654 Pages | ISBN: 9400748833 | PDF | 5 MB
This completely updated fifth edition of Bacterial Fish Pathogens is a comprehensive discussion of the biological aspects of the bacteria which cause disease in farmed and wild fish. Since the 4th edition was published in 2007, there has been an upturn in the application of molecular approaches to taxonomy, diagnosis and vaccine development. New pathogens, e.g. Aeromonas schubertii, have been described. Also, there has been the emergence of diseases caused by bacteria which have not been cultured, and which have been equated with new taxa, i.e. 'Candidatus'. Consideration is given to all the bacterial fish pathogens, including primary pathogens and opportunists.

Free Download Bacteria in Agrobiology: Plant Probiotics By Carla Spence, Emily Alff, Deepak Shantharaj (auth.), Dinesh K. Maheshwari (eds.)
2012 | 374 Pages | ISBN: 3642275141 | PDF | 4 MB
The future of agriculture strongly depends on our ability to enhance productivity without sacrificing long-term production potential. An ecologically and economically sustainable strategy is the application of microorganisms, such as the diverse bacterial species of plant growth promoting bacteria (PGPB). The use of these bio-resources for the enhancement of crop productivity is gaining worldwide importance. "Bacteria in Agrobiology: Plant Probiotics" discusses the current trends and future prospects of beneficial microorganisms acting as Probiotics. Topics include the application for the aboveground fitness of plants, in mountain ecosystems, in tropical and Mediterranean forests, and in muga sericulture. Further aspects are Arabidopsis as a model system for the diversity and complexity of plant responses, plant parasitic nematodes, nitrogen fixation and phosphorus nutrition.

Free Download Bacillus thuringiensis Biotechnology By Estibaliz Sansinenea (auth.), Estibaliz Sansinenea (eds.)
2012 | 392 Pages | ISBN: 9400730209 | PDF | 5 MB
Bacillus thuringiensis (Bt) has been used as a biopesticide in agriculture, forestry and mosquito control because of its advantages of specific toxicity against target insects, lack of polluting residues and safety to non-target organisms. The insecticidal properties of this bacterium are due to insecticidal proteins produced during sporulation. Despite these ecological benefits, the use of Bt biopesticides has lagged behind the synthetic chemicals. Genetic improvement of Bt natural strains, in particular Bt recombination, offers a promising means of improving efficacy and cost-effectiveness of Bt-based bioinsecticide products to develop new biotechnological applications. On the other hand, the different Bacillus species have important biotechnological applications; one of them is carried out by producing secondary metabolites, which are the study object of natural product chemistry. The amazing structural variability of these compounds has attracted the curiosity of chemists and the biological activities possessed by natural products have inspired the pharmaceutical industry to search for lead structures in microbial extracts. Screening of microbial extracts reveals the large structural diversity of natural compounds with broad biological activities, such as antimicrobial, antiviral, immunosuppressive, and antitumor activities that enable the bacterium to survive in its natural environment. These findings widen the target range of Bacillus spp., in special B. thuringiensis, besides insecticidal activity and help people to better understand its role in soil ecosystem.

Free Download Efraim Sicher, "Babel' in Context: A Study in Cultural Identity "
English | ISBN: 1936235951 | 2012 | 312 pages | PDF | 15 MB
Isaak Babel' (1894-1940) is arguably one of the greatest modern short story writers of the early twentieth century. Yet his life and work are shrouded in the mystery of who Babel' was―an Odessa Jew who wrote in Russian, who came from one of the most vibrant centers of east European Jewish culture, and who all his life loved Yiddish and the stories of Sholom Aleichem This is the first book in English to study the intertextuality of Babel''s work. It looks at Babel''s cultural identity as a case study in the contradictions and tensions of literary influence, personal loyalties, and ideological constraint. The complex and often ambivalent relations between the two cultures inevitably raise controversial issues that touch on the reception of Babel' and other Jewish intellectuals in Russian literature, as well as the "Jewishness" of their work.

Axe–heads and Identity An investigation into the roles of imported axe–heads in identity formation in Neolithic Britain

Free Download Katharine Walker, "Axe-heads and Identity: An investigation into the roles of imported axe-heads in identity formation in Neolithic Britain"
English | ISBN: 1784917443 | 2018 | 334 pages | PDF | 153 MB
The significant body of stone and flint axe-heads imported into Britain from the Continent has been poorly understood, overlooked and undervalued in Neolithic studies, particularly over the past half century. It is proposed, in this study, that the cause is a bias of British Neolithic scholarship against the invasion hypothesis and diffusionist model, and it is sought therefore to re-assess the significance accorded to these objects. The aim is to redress the imbalance by re-focusing on the material, establishing a secure evidence base, and exploring the probable conditions in which these often distinctive items made their way to Britain. The narrative presented here rests upon the argument that imported axe-heads came into what is today called Britain as objects of considerable significance. Specifically, they were items of high symbolic value that played a crucial role in fostering particular ways of thinking about, and addressing, social identity in the Neolithic period. These issues are the context for the study, whose main objectives are the close and detailed cataloguing of relevant material, and a documentation of the investigative work needed to establish the credentials of each artefact.

Avian Ancestors A Review of the Phylogenetic Relationships of the Theropods Unenlagiidae, Microraptoria, Anchiornis and Scanso

Free Download Avian Ancestors: A Review of the Phylogenetic Relationships of the Theropods Unenlagiidae, Microraptoria, Anchiornis and Scansoriopterygidae By Federico L. Agnolín, Fernando E. Novas (auth.)
2013 | 96 Pages | ISBN: 9400756364 | PDF | 2 MB
Although consensus exists among researchers that birds evolved from coelurosaurian theropods, paleontologists still debate the identification of the group of coelurosaurians that most closely approaches the common ancestor of birds. The last 20 years witnessed the discovery of a wide array of avian-like theropods that has considerably amplified the anatomical disparity among deinonychosaurians, some of which resemble Archaeopteryx more than Deinonychus. Among these newly discovered theropods that show remarkable bird-like characteristics are the four-winged theropods Microraptor and Anchiornis, and the unenlagiids Unenlagia, Buitreraptor, and Rahonavis. A bizarre group of minute-sized coelurosaurs, the Scansoriopterygidae, also exhibits some avian similarities that lead some authors to interpret them as more closely related to birds than other dinosaurs. With the aim to explore the phylogenetic relationships of these coelurosaurians and birds, we merged recently published integrative databases, resulting in significant changes in the topological distribution of taxa within Paraves. We present evidence that Dromaeosauridae, Microraptoria, Unenlagiidae, and Anchiornis + Xiaotingia form successive sister taxa of Aves, and that the Scansoriopterygidae are basal coelurosaurians not closely related to birds. The implications in the evolutionary sequence of anatomical characters leading to birds, including the origin of flight, are also considered in light of this new phylogenetic hypothesis.
