Wetland ecosystems and the amazing diversity of plants and animals that inhabit them are thought to be more threatened than any other ecosystem. The Okavango Delta, as the world's largest inland delta, is no exception. This book, published for World Wetlands Day, is both a celebration of the diversity of aquatic life in the Okavango Delta, and is an inspiration to decision makers throughout the region to work together to ensure the survival of one of the world's most beautiful and valuable wetlands. Few natural places in the world offer so much value to people in combination with such aesthetic appeal. Beginning with an explanation of the functioning of the Delta, the book describes (with the aid of many excellent graphics), the catchment areas in Angola and the passage of the Okavango River through Namibia, and goes on to reveal the physical, hydrological and ecological processes governing the working of the Delta itself. Subsequent chapters reveal the value of the Delta in

This book sets a high standard for rigor and scientific approach to the study of bilingualism and provides new insights regarding the critical issues of theory and practice, including the interdependence of linguistic knowledge in bilinguals, the role of socioeconomic status, the effect of different language usage patterns in the home, and the role of schooling by single-language immersion as opposed to systematic training in both home and target languages. The rich landscape of outcomes reported in the volume will provide a frame for interpretation and understanding of effects of bilingualism for years to come.
Kortit sen kertovat. Rouva Nolan on povannut tarokkikorteista, että Lucylle soivat hääkellot "ennen kuin lehdet putoavat puusta toisen kerran". Totta puhuen Lucy ei edes ole onnistunut löytämään poikaystävää. Hääuutisen kuullessaan Lucyn kämppäkaverit kauhistuvat. Jos Lucy muuttaa pois, heidän ihana elämäntyylinsä on mennyttä: noutoateriat, viinin litkiminen, miesvieraat, imuroinnin välttely. Mutta Lucy vakuuttaa, että hänellä on ihan tarpeeksi hommia kun pitää riidellä äidin kanssa ja pitää huolta vastuuttomasta isästä - ei hän ehdi ajatellakaan naimisiinmenoa. Ratkaisematta on sekin pieni pulma, ettei hänellä ole poikaystävää. Mutta sitten Lucy tapaa Gu...
This book represents an attempt to review the most recent knowledge concerning basic processes occurring in the most important female reproductive organ -- the ovaries and their regulators. The most important processes (ovarian cyclic changes and oogenesis), as well as their extracellular (hormones and growth factors) and intracellular (protein kinases, transcription factors, small RNAs) regulators are described. Data concerning processes or substances well described in previous reviews are summarised here in a short form with references to corresponding reviews.

In 1865, British polymath Francis Galton published his initial thoughts about the scientific field that would become 'eugenics.' The same year, Russian physician Vasilii Florinskii addressed similar issues in a sizeable treatise, entitled Human Perfection and Degeneration. Initially unheralded, Florinskii's book would go on to have a remarkable afterlife in twentieth- and twenty-first-century Russia. In this lucid and insightful work, Nikolai Krementsov argues that the concept of eugenics brings together ideas, values, practices, and fears energised by a focus on the future. It has proven so seductive to different groups over time because it provides a way to grapple with fundamental existen...
