Membranes are an energy efficient separation technology that are now the basis for many water treatment and food processing applications. However, there is the potential to improve the operating performance of these separations and to extend the application of membranes to energy production, gas separations, organic solvent-based separations, and biomedical applications through novel membrane materials. This book contains 20 chapters written by leading academic researchers on membrane fabrication and modification techniques and provides a comprehensive overview on the recent developments of membrane technology. Membranes can be manufactured from a range of materials including polymeric compounds, and ceramic materials, and both these materials are considered in the book. There are 5 chapters on water and wastewater membranes that cover the fabrication of thin film (TFC) composite membranes for nanofiltration(NF)/reverse osmosis (RO)/forward osmosis (FO) applications, stimuli responsive membranes, electrospun membranes, porous ceramic membranes, and polymeric ultrafiltration (UF) manufacture and modification. There are another 6 chapters on gas separation that consider carbon membranes, zeolite membranes, silica template and metal oxide silica membranes, TFC membranes, silica membranes, and metal organic framework (MOF) membranes. Zeolite membranes are also considered for organic solvent applications, as are solvent-resistant membranes manufactured by phase inversion, ceramic-supported composite membranes, and ceramic NF membranes. The emerging areas of membranes for energy and biomedical applications have 3 and 2 chapters, respectively. Energy applications consider ion exchange membranes for use in fuel cells, membranes for electrodialysis, and membranes for use in microbial fuel cells. For biomedical applications the chapters focus on hemodialysis membranes and redox responsive membranes.

The National Center for Intermedia Transport Research (NCITR) was established at UCLA in 1982 by EPA as one of six Centers of Excellence for the study of environmental pollution problems. One of the functions undertaken by the NCITR has been to hold periodic workshops and to provide a forum for the discussion of current topiCS in the environmental pollution arena. To this end, two other workshops have previously been held. The first, held in November 1982, was chaired by H. R. Pruppacher, R. G. Semonin and W. G. N. Slinn on Precipitation Scavenging, Dry DepOSition and Resuspension. The second, held in January 1986, was chaired by Y. Cohen on Pollution Transport and Accumulation in a Multimedia Environment. The present workshop, chaired by D. T. Allen, Y. Cohen and I. R. Kaplan, was held on August 24-26, 1988 in Santa Monica, California. The title of the workshop was Intermedia Pollutant Transport: Modeling and Field Measurements. Approximately one hundred individuals participated and twenty five papers were given, mostly by invitation. The workshop was divided into the following four broad topiCS: 1) Transport of Pollutants from the Atmosphere, 2) Transport of Pollutants from Soils and Groundwaters, 3) Transport of Pollutants from Lakes and Oceans, and 4) Multimedia Transport of Pollutants. The last afternoon was reserved for a Panel Discussion.

Pollutants released to the environment are distributed among the many environmental media such as air, water, soil, and vegetation, as the result of complex physical, chemical and biological processes. The possible environmental impact associated with chemical pollutants is related to their concentration levels and persistence in the various environmental compartments. Therefore, information regarding the migration of pollutants across environmental phase boundaries (eg., air-water, soil-water) and their accumulation in the environment is essential if we are to assess the potential environmental impact and the associated risks. In recent years it has become apparent that environmental pollution is a multimedia problem. Risk assessment and the design of appropriate pollution control measures require that we carefully consider the transport and accumulation of pollutants in the environment. We are now recognizing that the environment must be considered as a whole, and the scientific and regulatory approaches must consider the interactions of environmental media. It is also becoming apparent that single-medium approaches are partial and often counter-productive. On the other hand any multimedia program must carefully consider the rate of each environmental medium in the overall multimedia scheme.

The city of Emar, modern Tell Meskene in Syria, is one of the most important sites of the western ancient Near East during the Late Bronze Age that have yielded cuneiform tablets. The discovery of more than one thousand tablets and tablet fragments assures Emar's position, along with Bogazkoy-Hattusa and Ras-Shamra-Ugarit, as a major scribal center. Ephemeral documents such as wills or sale contracts, texts about rituals and cultic festivals, school texts and student exercises, and inscribed seals and their impressions enable reconstruction of the Emar scribal school institution and provide materials for investigation into the lives of more than fifty scribes whose works were found in the city. The aim of this book is to place Emar's scribal school institution within its social and historical context, to observe the participation of its teachers and students in the study of the school curriculum, to investigate the role of the scribes in the daily life of the city (in particular within the administration), and to evaluate the school's and its members' position within the network of similar institutions throughout the ancient Near East.

The IOS Annual Volume 21: “Carrying a Torch to Distant Mountains”, brings forth cutting-edge studies devoted to a wide array of fields and disciplines of the Middle East. The three sections—the Ancient Near East, Semitic Languages and Linguistics, and Arabic Language and Literature—include sixteen articles. In the Ancient Near East section are studies devoted to Babylonian literature (Gabbay and Wasserman; Ayali-Darshan), history (Cohen and Torrecilla), and language (Zadok). The Semitic Languages and Linguistics section contains discussions about comparative Semitics—Egyptian and Modern South Arabic (Borg; Cerqueglini), Aramaic dialects (Khan; Stadel), Palestinian Arabic (Arnold; Procházka), and Tigre and Ethiosemitic languages (Voigt). The final section of Arabic Language and Literature is devoted to ʿArabiyya and its grammarians (Dror, Versteegh, Sheyhatovitch, Kasher, and Sadan).

The IOS Annual volume 22: “Telling of Olden Kings” brings forth studies devoted to a wide array fields and disciplines of the Middle East. The Ancient Near East section is devoted to Neo-Babylonian Mesopotamia and the Achaemenid Empire (Da Riva and Novotny; Levavi; Tavernier and Azzoni; Zadok). The Semitic section includes three articles dealing with contact between various languages of the Semitic language group and between Semitic languages and dialects and other language groups (Castagna; Cerqueglini; Klimiuk and Lipnicka). The Arabic section contains two articles two articles about Modern Iraqi and Egyptian Poetry (Khoury) and the image of Rahav the harlot in early Muslim traditions (Yavor).

Volume 24 of the Israel Oriental Studies Annual includes eight articles. The Ancient Near Eastern section consists of five articles. Four deal with Hittite and Anatolian subjects (Burgin, Gilan, Cohen and Hawkins); one discusses the “Laws of Hazor” text fragment and its relationship to other cuneiform law collections (Darabi). The Semitic section includes three articles. The first is the second instalment of Etymogical Investigations on Jibbali/Śḥerέt Anthroponyms (Castagna and Al-'amri). The second article is a discussion of the relationship between Ethiopian Semitic languages and ancient Egyptian (Cerqueglini). Sealing the Semitic section and volume 24 is a study of spoken Ashkenazic Hebrew among Hassidic communities (Yampolskaya et al.).
