Synopsis Filicum Africae Australis, Or, An Enumeration of the South African Ferns Hitherto Known by Karl Wilhelm Ludwig Pappe,Sir Rawson William Rawson Pdf
Mollusc species currently constitute a major threat to sustainable agriculture. This threat is associated with cultivation of new crops, intensification of agricultural production systems and the spread through human trade and travel of species adapted to these modified environments. In some crops their significance is only now becoming apparent with the decline in the importance of other pest groups which can be effectively controlled. The book focuses on: toxicology of chemicals; deployment of molluscicides in baits; specific crop situations worldwide; current pest status of mollusc species and progress towards development of solutions.
Lemur Social Systems and Their Ecological Basis by J. Ganzhorn,P.M. Kappeler Pdf
The past decade has seen a steady increase in studies oflemur behavior and ecology. As a result, there is much novel information on newly studied populations, and even newly discovered species, that has not yet been published or summarized. In fact, lemurs have not been the focus of an international symposium since the Prosimian Biology Conference in London in 1972. Moreover, research on lemurs has reached a new quality by addressing general issues in behavioral ecology and evolutionary biology. Although lemurs provide important comparative information on these topics, this aspect of research on lemurs has not been reviewed and compared with similar studies in other primate radiations. Thus, as did many in the field, we felt that the time was ripe to review and synthesize our knowledge of lemur behavioral ecology. Following an initiative by Gerry Doyle, we organized a symposium at the XIVth Congress of the International Primatological Society in Strasbourg, France, where 15 contributions summarized much new information on lemur social systems and their ecological basis. This volume provides a collection of the papers presented at the Strasbourg symposium (plus two reports from recently completed field projects). Each chapter was peer-reviewed, typically by one "lemurologist" and one other biologist. The first three chapters present novel information from the first long-term field studies of three enigmatic species. Sterling describes the social organization of Daubentonia madagascariensis, showing that aye-aye ranging patterns deviate from those of all other nocturnal primates.

Efficient Desalination by Reverse Osmosis by Stewart Burn,Stephen Gray Pdf
Early applications of desalination were small-scale plants deploying a range of technologies. However with the technological developments in Reverse Osmosis, most new plants use this technology because it has a proven history of use and low energy and capital costs compared with other available desalination technologies. This has led to the recent trend for larger seawater desalination plants in an effort to further reduce costs, and 1000 MLD seawater desalination plants are projected by 2020. Efficient Desalination by Reverse Osmosis recognises that desalination by reverse osmosis has progressed significantly over the last decades and provides an up to date review of the state of the art for the reverse osmosis process. It covers issues that arise from desalination operations, environmental issues and ideas for research that will bring further improvements in this technology. Efficient Desalination by Reverse Osmosis provides a complete guide to best practice from pre-treatment through to project delivery. Editors: Stewart Burn, Visiting Scientist, CSIRO Manufacturing.

Clear English Pronunciation provides students with the tools to effectively communicate in English without centring solely on native-speaker pronunciation models. The focus of the book is on individual pronunciation targets rather than a one-size-fits-all approach. Divided into four sections, each featuring detailed articulatory explanations, sample sentences, and recordings to help learners improve their pronunciation, this book: introduces the phenomenon of pronunciation as part of a broader communicative realm; explains and demonstrates the melody and rhythm of understandable and natural English pronunciation; supports students in identifying and practicing their own pronunciation issues. Supported by an interactive companion website which features recordings and expanded explanations of key topics, Clear English Pronunciation is an essential textbook for international learners of English who want to improve their pronunciation skills in diverse social settings. For more resources on English pronunciation, visit: englishpronunciationcentral.universiteitleiden.nl Additionally, you can find recordings of a wide range of speakers here: https://www.universiteitleiden.nl/clearenglishpronunciation
Tropical Forests in Transition by J. Goldammer Pdf
In evolutionary time scales natural disturbances have affected the vegetation on Earth. During the Quaternary the forest biomes of the tropics were subjected to manifold disturbances. Climate changes and climate oscillations were associated with changing precipitation and drought regimes, flooding, siltation, landslides, etc. The prehistorical forest was also influenced by the effects of large wildlife populations. Large-scale catastrophies in the forest biomes were mainly caused by abiotic environmental alterations, the small-scale disturbances were and still are related to both biotic and abiotic processes. Both the large-and the small-scale disturbances have played a significant role in shaping distribution, dynamics, structure and composition of the paleoforest. After the expansion of hominids and early humans, and later, by modern humans, the anthropogenic influences on the tropical forest began to overlap natural disturbances. Today's anthropogenic impacts on the tropical forests differ qualitatively and quanitatively from the natural disturbances. The speed of tropical deforestation and savannization is dramatically increasing. The physical and chemical impacts of forest conversion and biomass burning add to other anthropogenic influences on the atmosphere and climate. The expected anthropogenic climate change will also have considerable impacts on the tropical flora and fauna. The book on "Tropical Forests in Transition" synthesizes information on changing environmental conditions and human impacts on the tropical forest by looking back to the paleoecology, analyzing the impact of modern human populations and modeling the future of the tropical forest in a changing environment. The aim of the book is to strengthen multidisciplinary thinking in disturbance ecology.
Cosmetic surgery is everywhere: we are surrounded by altered, enhanced, skinny and stretched celebrities, in a hyped media culture that focuses increasingly on the body beautiful. Once only associated with the rich and famous, cosmetic surgery is now widely available, advertised in magazines, doctors' surgeries, and even on television. In some parts of the world it has become an aesthetic and cultural norm, yet remains deeply troubling for many. Skintight argues that cosmetic surgery is the most provocative and controversial aspect of a new 'makeover culture'. Shows such as Ten Years Younger and Extreme Makeover demonstrate that 'fixing' the body is a way to improve lifestyle and uncover true identity. Meanwhile, celebrities such as Michael Jackson and Jocelyn Wildenstein demonstrate the horrors of extreme surgical alteration. Presenting a multidisciplinary approach, and examining a wide range of popular culture case studies from women's magazines, television, architecture and the Internet amongst others, Skintight dissects the realities of cosmetic surgery and culture.
