Flocs in Water Treatment is the first of its kind - serving as a valuable aide-mémoire for scientists, process engineers and other professionals engaged in water treatment. The framework described in Flocs in Water Treatment can also be applied to aggregated solids found both in the natural environment, and within a broad range of industries. Flocs (aggregated solid matter) resulting from the combined influence of coagulation and flocculation play a vital role in solid-liquid separation processes. The design and operation of water treatment plants demands a proper understanding of the ways in which flocs affect treatment systems and how their properties can be manipulated to increase treatment efficiency. Flocs in Water Treatment provides a comprehensive account of the ways in which flocs are formed, their characterization, and how they behave in practice. Flocs are complex entities, whose properties defy easy description and measurement. In spite of this, the authors provide a clear and discerning account of the current state of knowledge; this is rooted in science and draws on many disciplines. Based on their experiences in research and the workings of full scale treatment plants, the authors offer candid advice on tasks such as the measurement of floc properties and guidance on problems involving the use of chemicals for controlling floc properties within treatment systems.
Demonstrates the applications for vegetation as an engineering medium and to evaluate its role in environmental control. Processes and problems in surface hydrology, drainage, slope stabilization, shelterbelts, land rehabilitation, soil erosion, irrigation and waste disposal are examined.
To address the growing complexities of childhood cancer, Nathan and Oski’s Hematology and Oncology of Infancy and Childhood has now been separated into two distinct volumes. With this volume devoted strictly to pediatric oncology, and another to pediatric hematology, you will be on the cutting edge of these two fields. This exciting new, full-color reference provides you with the most comprehensive, authoritative, up-to-date information for diagnosing and treating children with cancer. It brings together the pathophysiology of disease with detailed clinical guidance on diagnosis and management for the full range of childhood cancers, including aspects important in optimal supportive care. Written by the leading names in pediatric oncology, this resource is an essential tool for all who care for pediatric cancer patients. Offers comprehensive coverage of all pediatric cancers, including less common tumors, making this the most complete guide to pediatric cancer. Covers emerging research developments in cancer biology and therapeutics, both globally and in specific pediatric tumors. Includes a section on supportive care in pediatric oncology, written by authors who represent the critical subdisciplines involved in this important aspect of pediatric oncology. Uses many boxes, graphs, and tables to highlight complex clinical diagnostic and management guidelines. Presents a full-color design that includes clear illustrative examples of the relevant pathology and clinical issues, for quick access to the answers you need. Incorporates the codified WHO classification for all lymphomas and leukemias.
In this book, leading researchers spotlight how dramatically the practice of adoption has changed both in North America and Europe in recent decades due to, among other factors, a falling rate of domestically born infants being placed for adoption. This has resulted in a rise in international adoption, children of color being placed with Caucasian parents, increased foster care and special needs adoptions including children exposed to prenatal alcohol and drug use as well as maltreatment by birth parents. Also examined is the far more diverse group of adults being granted adoption rights, including single and homosexual parents. Research findings demonstrate the trend across countries toward open adoption, wherein the birth parents and adoptive parents meet to share information. As the editors note, there is no longer a typical adopted child or a typical adoptive family. Paralleling these changes has been a growing interest in the study of adopted children and adoptive parents. Although earlier research showed adoptees more likely to experience school problems and psychological disorders, recent studies show the differences in these areas between adoptees and non-adoptees to be relatively small. Models guiding adoption research are beginning to emphasize resilience and positive adaptation, rather than risk and psychopathology. This handbook will be of interest to all involved with adoption policy and practice.
