        Practical R for Biologists

        An Introduction

        by Donald Quicke, Buntika A Butcher, Rachel Kruft Welton

        R is a freely available, open-source statistical programming environment which provides powerful statistical analysis tools and graphics outputs. R is now used by a very wide range of people; biologists (the primary audience of this book), but also all other scientists and engineers, economists, market researchers and medical professionals. R users with expertise are constantly adding new associated packages, and the range already available is immense.This text works through a set of studies that collectively represent almost all the R operations that biology students need in order to analyse their own data. The material is designed to serve students from first year undergraduates through to those beginning post graduate levels. Chapters are organized around topics such as graphing, classical statistical tests, statistical modelling, mapping, and text parsing. Examples are based on real scientific studies, and each one covers the use of more R functions than those simply necessary to get a p-value or plot.The book walks the reader through the data analysis process, starting with very simple plots, and continuing through more complex analyses and programming. It shows how to deal with issues such as error messages that can be confronting for beginners, in order to set students up for a successful scientific career using R.Collectively the authors have a vast amount of teaching experience which they apply here to make the passage into R programming as gentle and easy as possible, whilst guiding the reader to tackle quite complicated programming.

        A oficina do Cambeva (Cambeva's workshop)

        by Lido Loschi

        Cambeva's workshop is the first of four books of the collection "Presente de Vô" in partnership with Grupo Ponto de Partida. The book is a mixture of colours and elements that highlight the memory of the world, in which seekers of memories have the mission of bringing light and life to objects found in the travels of two characters: Zalém and Calunga. Cambeva is a restorer who, when the world lost its embrace, tried to reinvent it; he is the grandfather who mends dreams, forgotten things and lost emotions, to whom the seekers ask for help to fix something. In a magical universe, full of children, grandchildren, stories and memories of his lineage of restorers, when faced with this request for restoration, he makes room to bring back an emblematic figure who can no longer sing. A story about memories, care and affection...

        A Partir de Rien

        by Ron Adam

        A Partir de RienUn thriller apocalyptique par Ron Adam Tout comme dans les tragédies grecques, l’Amérique va droit à la collision inévitable avec l’ultime menace : la combinaison fatale de l’Islam fanatique avec les armes nucléaires et les ressources énergétiques les plus riches du monde. Le 11 septembre 2001, Osama Bin Laden a démontré au monde comment on pouvait aisément retourner les dollars américains et la technologie des Etats-Unis et les utiliser comme un boomerang frappant droit au cœur de l’Amérique. Il est à la fois facile et terrible d’imaginer ce qui peut arriver si un tel zèle fanatique réussit à s’équiper de la puissance monstrueuse des armes nucléaires.Un coup d’œil rapide à la carte montre que les Etats-Unis ont appris la leçon et que les guerres en Afghanistan et en Iraq doivent juste refermer le cercle autour de la menace véritable – l’Iran.A Partir de Rien vous entraîne dans le tourbillon qui balaie le monde, depuis une guerre locale dans le Golfe Persique, en passant par un coup d’état militaire en Russie - la nouvelle ancienne alliée de l’Iran – jusqu’à un véritable holocauste nucléaire.L'équipe d'un sous-marin américain, constituée d'hommes uniquement, qui sans le vouloir, a joué un rôle actif dans la destruction de l’humanité, découvre au lendemain de la catastrophe que c’est sur ses épaules qu’incombe d’accomplir la tâche opposée – recréer la race humaine – A Partir de Rien. Après neuf mois passés sous l’eau, ils vont émerger vers une île lointaine du Pacifique sur laquelle les conditions peuvent de nouveau supporter la vie. Equipés des technologies les plus sophistiquées, ils emportent avec eux deux douzaines d’ovaires fertilisés congelés, qui sont chacun destinés à devenir une nouvelle Eve, et qui, ensemble, constitueront les mères d’une nouvelle humanité.Cependant les « Adams » sont malheureusement trop nombreux sur cette île ! Plus d’une centaine d’hommes attendent impatiemment que les 24 petites filles grandissent pour mûrir et devenir des femmes, et le combat pour prendre contrôle de cette précieuse « ressource » est par conséquent inévitable.Ces hommes découvrent que la nature humaine ne peut être changée. Même après la guerre ultime qui a tout détruit, l’homme continuera à se servir de la force pure pour obtenir ce qu’il veut et pour résoudre les disputes.En dépit de sa trame pessimiste, le livre est essentiellement optimiste et est guidé par la foi dans la loi de l’histoire : il se peut que les bons doivent souffrir et payer un lourd tribut mais, à la fin du compte, ils gagneront.L’auteur : un pilote de chasse, officier naval et ingénieur supérieur de Hi-Tech. Ron Adam a mené une carrière militaire impressionnante, du service dans un sous-marin et un torpilleur de la marine israélienne en passant par l’aviation israélienne comme pilote de chasse, capitaine sur un porte-avions, instructeur de vol et officier du personnel de guerre électronique. Possédant un diplôme d’ingénieur en électronique, Adam a dirigé un programme de défense de 1,2 milliards de dollars et a également fondé trois entreprises start-up dans le high-tech. Aujourd’hui, Adam est ingénieur-conseil supérieur dans les industries aéronautiques et il partage son temps entre la technique de haut niveau et l’écriture de livres et de scénarios. Il est marié et a trois enfants.

        Gene-for-Gene Relationship in Plant-Parasite Interactions

        by Edited by Ian R Crute, Eric B Holub, Jeremy J Burdon

        Genetics has transformed plant pathology on two occasions: first when Mendelian genetics enabled the discovery that disease resistance was a heritable trait in plants, and secondly when Flor proposed the “gene-for-gene” hypothesis to explain his observations of plant-parasite interactions, based on his work on flax rust in North Dakota starting in the 1930s. Our knowledge of the genetics of disease resistance and host-pathogen coevolution is now entering a new phase as a result of the cloning of the first resistance genes. This book provides a broad review of recent developments in this important and expanding subject. Both agricultural and natural host-pathogen situations are addressed. While most of the book focuses on plant pathology, in the usual sense of the term embracing fungal, bacterial and viral pathogens, there is also consideration of parasitic plants and a chapter demonstrating lessons to be learnt from the mammalian immune system. Three overall themes are addressed: genetic analyses and utilization of resistance; population genetics; and cell biology and molecular genetics. Chapters are based on papers presented at the British Society for Plant Pathology Presidential meeting held in December 1995, but all have been revised and updated to mid-1996. Written by leading authorities from North America, Europe and Australia, the book represents an essential update for workers in plant genetics, breeding, biotechnology and pathology.

        A Supplement of the Faery Queene

        By Ralph Knevet

        by J. B. Lethbridge

        Ralph Knevet's Supplement of the Faery Queene (1635) is a narrative and allegorical work, which weaves together a complex collection of tales and episodes, featuring knights, ladies, sorcerers, monsters, vertiginous fortresses and deadly battles - a chivalric romp in Spenser's cod medieval style. The poem shadows recent English history, and the major military and political events of the Thirty Years War. But the Supplement is also an ambitiously intertextual poem, weaving together materials from mythic, literary, historical, scientific, theological, and many other kinds of written sources. Its encyclopaedic ambitions combine with Knevet's historical focus to produce an allegorical epic poem of considerable interest and power. This new edition of Knevet's Supplement, the first scholarly text of the poem ever published, situates it in its literary, historical, biographical, and intellectual contexts. An extensive introduction and copious critical commentary, positioned at the back of the book, will enable students and scholars alike to access Knevet's complicated and enigmatic meanings, structures, and allusions. ;

        Amelie Trott and the Earth Watchers

        by Moyra Irving

        This is the extraordinary story of how one small girl stopped a planetary catastrophe. It’s a very timely book, written for the child in us all, with a forceful message about the power of young people to transform the world - a theme currently demonstrated by brave young heroes like Greta Thunberg. And with magical synchronicity, the very week Greta began her lone vigil outside the Swedish government last year, over 1,000 miles (1,897 km) away in the fictional world of books, Amelie Trott took to Parliament Square, London - on a mission to avert the End of the World. It’s a family drama with an international feel - set mainly in England but with episodes in Washington DC and around the world.

        Phosphorus Loss from Soil to Water

        by Edited by H Tunney, P C Brookes, A E Johnston

        Phosphorus is an essential element for plant growth and its input has long been recognised as necessary to maintain profitable crop production. However, phosphorus inputs can also increase the biological activity of surface waters and this can lead to the destruction of such aquatic ecosystems. Advanced eutrophication of surface water leads to problems with its use for fisheries, recreation, industry and drinking, due to the increased growth of undesirable algae and aquatic weeds, and oxygen shortages caused by their death and decomposition. It is therefore important to have a good understanding of the causes and mode of phosphorus loss from soil to water, to enable the problems to be controlled and managed. This book has been developed from an international workshop held in Ireland in late 1995. It is the first comprehensive consideration of the topic, and many leading researchers in the area have contributed to it. It is essential reading for all soil scientists and freshwater biologists, as well as for environmentalists, ecologists and agriculturalists concerned with sustainable land management and pollution. The book is also recommended to fisheries managers, fertilizer manufacturers and biologists working for water utilities.

        by H. C. Artmann, Klaus Reichert

        Von allen deutschen Autoren, die nach 1945 zu schreiben begannen, ist Artmann ohne jeden Zweifel der vielseitigste, originellste und erfinderischste. So wie Artmann in fast allen Gattungen gearbeitet hat, auch den angeblich antiquierten, und ohne sich um die Tagesparolen der mal reine Dichtung betreibenden, mal engagierten, mal die Literatur totsagenden Kollegen zu kümmern, so hat er seine Quellen, seine Herkunft überall: in der Artusepik, in barocker Schäferpoesie, in den Wörterbüchern und Grammatiken von gut zwei Dutzend Sprachen, in Irland und im England des Sherlock Holmes, bei Villon und dem Wiener Vorstadtdialekt, Lorca, Gomez de la Serna, den Surrealisten und Dadaisten, in den Detektivheftchen der 20er Jahre und den Comic strips von damals bis heute. Unsere Auswahl versucht, nicht nur einen repräsentativen Querschnitt durch das Werk Artmanns zu geben, sondern gleichzeitig Verstreutes, an entlegensten Orten Publiziertes zu sammeln.

Duvall, Martin Farr, John Heeley, Andrew Holden, Stanislav Ivanov, Heather Jeffrey, Gabriele Manella, Chris Ryan, Asterio Savelli, Hongdi Shen, John E Tunbridge, David Weaver, Paul F Wilkinson

        This new book reviews all aspects of the phenomenon of mass tourism. It covers theoretical perspectives (including political economy, ethics, sustainability and environmentalism), the historical context, and the current challenges to domestic, intra-regional and international mass tourism. As tourism and tourist numbers continue to grow around the world, it becomes increasingly important that this subject is studied in depth and best practice applied in real-life situations. This book: - Is the first to address a range of theoretical issues relating to mass tourism; - Uses a wide selection of case studies to translate theory into practice, covering the historical rise and fall of UK seaside resorts, the increase in Chinese tourism, conflict between different mass tourism groups, destination transformation from mass to niche tourism, and specific problems facing cruise ships; - Is written by a range of international, established authors to give a global perspective on the subject. Finishing with a speculative chapter identifying potential future trends and challenges, this book forms an essential resource for all researchers and students within tourism studies. ; Section 1: Introduction1: Introduction: Mass Tourism in a Small WorldSection 2: Theoretical Approaches to Mass Tourism2: Mass Tourism Does Not Need Defending3: The Morality of Mass Tourism4: The Political Economy of Mass Tourism and its Contradictions5: A Theoretical Approach to Mass Tourism in Italy6: Sustainability and Mass Tourism: A Contradiction in Terms?7: Mass Tourism and the Environment: Issues and DilemmasSection 3: Historical Studies of Tourism Development8: The Dynamics of Tourism Development in Britain: The Profit Motive and that ‘Curious’ Alliance of Private Capital and the Local State9: From Holiday Camps to the All-inclusive: the ‘Butlinization’ of Tourism10: Decline Beside the Seaside: British Seaside Resorts and Declinism11: Mass Tourism and the US National Park Service System12: Transport and Tourism: The Perpetual LinkSection 4: Case Studies in Modern Mass Tourism13: Mass Tourism and China14: Mass Tourism in Thailand: The Chinese and Russians15: Mass Tourism in Bulgaria: The Force Awakens16: Mass Tourism in Mallorca: Examples from Calivià17: Tunisia: Mass Tourism in Crisis?18: From Blue to Grey?
