This book covers the topic of microplastics in water and wastewater. The chapters start with introductory issues related to the growing interest in the scientific community on microplastics and the human water cycle and point out where the microplastics could interact with water. The subsequent chapters examine evidence of the microplastic presence in freshwater, such as in both rivers and lakes, in freshwater biota, and hazardous chemicals associated with microplastics in such systems. Another set of chapters discuss the presence of microplastics in wastewater: their sources; their transfer through a wastewater treatment plant; the concentration of microplastics in effluents throughout the ...

The book by Dr. Taddesse Tamrat is an important contribution. ... In fact, the author shows his full and precise knowledge of past literature on Ethiopia, and his critical analysis of historical events is well founded on the results of recent work; but also-and this is an important novelty-he had access to hagiographical and historical documents, kept in Ethiopian monasteries, which had not previously been known to scholars. ... - Professor Enrico Cerulli, in BSOAS, Vol. 37, 1972. Once in a long while, books are written that set the standard in their discipline. Taddesse Tamrat's Church and State has been just such a book, a classic in Ethiopian historiography, unsurpassed in its painstaking...
This second volume by Bruce Murray looks at Wits University's role in South Africa's war effort, its contribution to the education of ex-volunteers after the war, its leading role in training job-seeking professionals, the rise of research and postgraduate study and the University's defence to preserve its 'open' status.
Examining the historical foundations, the struggle to establish a university in Johannesburg, and the progress of the University in the two decades prior to World War II, historian Bruce Murray captures the quality and texture of life in the early years of Wits University and the personalities who enlivened it and contributed to its growth.
Space flight is a comprehensive and innovative part of technology. It encompasses many fields of technology. This monograph presents a cross section of the total field of expertise that is called "space flight". It provides an optimal reference with insight into the design, construction and analysis aspects of spacecraft. The emphasis of this book is put on unmanned space flight, particularly on the construction of spacecraft rather than the construction of launch vehicles.
Containing thousands of entries of both vernacular and scientific names of Great Plains plants, the literature that informs this exhaustive listing spans nearly 300 years. Author Elaine Nowick has drawn from sources as diverse as Linnaeus, Lewis and Clark, and local university extension publications to compile the gamut of practical, and often fanciful, common plant names used over the years. Each common name is accompanied by a definitive scientific name with references and authority information. Interspersed with scientifically-correct botanical line drawings, the entries are written in standard ICBN format, making this a useful volume for scholars as well as lay enthusiasts alike. Volume 2 indexes the scientific names of those species, followed by listings of all the common names applied to them. Both volumes refer the common and scientific names back to a list of 190 pertinent authoritative sources.

Italy's long-standing aspiration for a 'place in the sun' was finally brought to fruition by Benito Mussolini, whose greatest achievement was perhaps the annexing of Ethiopia in 1935-1936. The focus of this carefully-researched volume is the economic policy and practice of Italy during their six years of occupation.
