Water of very low mineral content, i.e. low ionic conductivity, is required in many industrial processes and laboratory applications. The demand for total output volume and purity of such water has been significantly increasing during the last decades. Electromembrane processes provide a more sustainable and cost effective water purification compared to alternative processes like distillation and ion-exchange deionization. In the first part of the publication a review of processes used for deionization of water is presented and main physicochemical phenomena occurring in electromembrane processes will be discussed. The subsequent parts are devoted to the experimental verification of novel im...
The Sealand kingdom arose from the rebellion against Babylonian hegemony in the latter half of the 18th century BCE., forcing it to share power over Sumer and Akkad. Although its kings maintained themselves throughout the turmoil leading to the demise of the Amorite dynasty at Babylon, it remains one of the most poorly documented Mesopotamian polities. Until recently, it was known to us mainly through its inclusion into later king lists and chronicles, but the recent publication of well over 400 archival texts from a Sealand palace, soon followed by literary and divinatory tablets, finally makes it possible to study this polity from primary sources. This book proposes a history of the Sealan...
Today our societies face great challenges with water, in terms of both quantity and quality, but many of these challenges have already existed in the past. Focusing on Asia, Water Societies and Technologies from the Past and Present seeks to highlight the issues that emerge or re-emerge across different societies and periods, and asks what they can tell us about water sustainability. Incorporating cutting-edge research and pioneering field surveys on past and present water management practices, the interdisciplinary contributors together identify how societies managed water resource challenges and utilised water in ways that allowed them to evolve, persist, or drastically alter their environ...
Securing Food for All in Bangladesh presents an array of research that collectively address four broad issues: (1) agricultural technology adoption; (2) input use and agricultural productivity; (3) food security and output market; and (4) poverty, food security, and women’s empowerment. The fifteen chapters of the book address diverse aspects within these four themes. Access to sufficient food by all people at all times to meet their dietary needs is a matter of critical importance. Despite declining arable agricultural land, Bangladesh has made commendable progress in boosting domestic food production. The growth in overall food production has been keeping ahead of population growth, resu...
This publication contains guidelines to sustain irrigated agriculture and protect water resources from the negative impacts of agricultural drainage water disposal. Using case studies from Central Asia, Egypt, India, Pakistan and the US, this study highlights four broad groups of drainage water management options and provides information to enable assessment of their impact and contribution towards development goals and to facilitate the preparation of drainage water management plans and designs. The options are: water conservation, drainage water re-use, drainage water disposal and drainage water treatment. The full texts of the case studies can be found on the attached CD-ROM.
