Given the enduring importance of Aristotle's Nicomachean Ethics, it is remarkable to find that there is no extensive surviving commentary on this text from the period between the second century and the twelfth century. This volume is focused on the first of the medieval commentaries, that produced in the early twelfth century by Eustratios of Nicaea, Michael of Ephesus, and an anonymous author in Constantinople. This endeavor was to have a significant impact on the reception of the Nicomachean Ethics in Latin and Catholic Europe. For, in the mid-thirteenth century, Robert Grosseteste translated into Latin a manuscript that contained these Byzantine commentators. Both Albertus Magnus and Bonaventure then used this translation as a basis for their discussions of Aristotle's book. Contributors are George Arabatzis, Charles Barber, Linos Benakis, Elizabeth Fisher, Peter Frankopan, Katerina Ierodiakonou, David Jenkins, Anthony Kaldellis and Michele Trizio.

Human Papillomavirus: Proving and Using a Viral Cause for Cancer presents a steady and massive accumulation of evidence about the role of HPV and prevention of HPV-induced cancer, along with the role and personal commitment of many scientists of different backgrounds in establishing global relevance. This exercise involved years of personal commitment to proving or disproving an idea that aroused initial skepticism, and that still has difficult implications for some. It remains one of the big successes of medicine that exploited both established medical science dating back to the nineteenth century and new molecular genetic science during a time of transition in medicine.

The terrorist attacks of 9/11 precipitated significant legal changes over the ensuing ten years, a "long decade" that saw both domestic and international legal systems evolve in reaction to the seemingly permanent threat of international terrorism. At the same time, globalization produced worldwide insecurity that weakened the nation-state's ability to monopolize violence and assure safety for its people. The Long Decade: How 9/11 Changed the Law contains contributions by international legal scholars who critically reflect on how the terrorist attacks of 9/11 precipitated these legal changes. This book examines how the uncertainties of the "long decade" made fear a political and legal force, challenged national constitutional orders, altered fundamental assumptions about the rule of law, and ultimately raised questions about how democracy and human rights can cope with competing security pressures, while considering the complex process of crafting anti-terrorism measures.

- questions how bureaucracies conceive of and consequently interact with nature, and suggests that our managed public landscapes are neither entirely managed nor entirely wild - questions which kinds of human influence, conceived of in the widest possible sense, will produce ideal environments for future generations, and who gets to choose - draws on the author's experience as an objective scholar and over 10 years working as a practitioner in federal land management agencies - will be of great interest to students and scholars of natural resource management, policy and politics, and professionals working in environmental management roles as well as policymakers involved public policy and administration.

The Activated Sludge (AS) Process is old technology but is still widely adopted worldwide for its convenience and simplicity: an impressive number (many hundred of thousands) of this kind of system are in operation. Occasionally, problems such as bulking and foaming occur, causing regulation violations and large investment is often required immediately to control them. For this reason, an intense research effort has been made during the last few decades to face these problems, and this report details the work undertaken by the IWA Specialist Group on Activated Sludge Population Dynamics. This Scientific and Technical Report describes the main reasons fslyuor the growth of the different filamentous microorganisms in activated sludge, and the biological molecular tools available today for the identification of the main biomass components. The wide range of experiences around the world is documented and the methods to avoid the proliferation of these organisms are presented and critically reviewed. Activated Sludge Separation Problems consists of seven chapters, presenting up-to-date technical and scientific aspects of these processes. Scientific and Technical Report No. 16

Anaerobic/aerobic (AnA) and completely aerobic (CA) laboratory-scale sequencing batch reactors operating on an acetate- and casamino acids-based synthetic wastewater were used to investigate the suitability of the AnA process for treating nutrient?deficient wastewaters in plants that have stringent effluent nutrient requirements. Of particular interest is the case where phosphorus (P)-deficient wastewaters with highly variable influent COD loading are being treated to meet both effluent TSS and P limits. At a 4 d mean cell residence time, AnA activated sludge had an approx. 20% lower P requirement than CA activated sludge. The difference between the end-of-aerobic cycle polyhydroxyalkanoate and carbohydrate contents of the sludges indicated that the AnAsludge used more influent carbon than the CA sludge for synthesis of non-P-containing storage products. The nitrogen requirements of AnA sludge were similar to those of the CA sludge. The AnA and CA SBRs were subjected to three different transient influent COD loading patterns that simulated (#1) daily COD Loading fluctuations, (#2) low weekend COD loading, and (#3) extended low COD loading periods. During the Loading Pattern #1 experiment, the average effluent soluble P concentrations for the AnA and CA SBRs were 0.4 and 1.0 mgP/L respectively, and complete removal of influent acetate was observed. During the Loading Pattern #2 experiment, the average effluent soluble P concentrations for the AnA and CA SBRs were 0.3 and 0.9 mgP/L respectively, but effluent acetate was detected during the first high COD loading cycle following the low weekend COD loading period. During the Loading Pattern #3 experiment, the VSS content of both reactors dropped sharply, effluent acetate breakthrough occurred, and effluent P concentrations exceeding 1 mgP/L were detected in both the AnA and CA SBRs. Based on these findings, the AnA process has potential as a technologically and economically superior alternative for wastewater treatment plants treating P-deficient wastewasters to meet stringent effluent TSS and P limits.

The most common activated sludge operating problems causing poor plant performance are related to solids separation. Especially common are bulking and foaming. Without a proper scientific foundation to support the efforts of wastewater treatment plant management, many attempts to thwart bulking and foaming have failed. Manual on Solving Activated Sludge Bulking, Foaming, and Other Solids Separation Problems provides the critical scientific and practical underpinnings needed to understand and combat these problems. The third edition of this flagship text is a comprehensive, concise guide to the microbiological and technical aspects of controlling all types of solid separation problems. The scientific theory is applied to real-world scenarios, greatly increasing the number of real-world examples of successful control methods. New information is also included on filamentous organism growth and its application in the control of sludge bulking and foaming. Now plant operators, regulators and wastewater engineers have a complete guide for battling these formidable design and operating problems.

Do your performance measures seek primarily to detect and control undesirable activities, rather than sharing and rewarding productive behaviour? Every organisation needs to measure its performance and that of the people it employs; David Jenkins shows you how to make more productive use of such measures. For measures to be accurate and reliable there are fundamental rules that need to be applied. Ignoring or misapplying them undermines performance and impedes the achievement of the corporate goal. For any enterprise, data must be available across the whole spectrum of activity in which it is engaged. The quality of that information will depend on the way it is measured. In some commercial organisations data is regularly gathered at local level. Instead of being used at this point, it is often fed into a corporate information system which, having recycled it, issues the result in a form that does not always meet needs. In Measuring Performance, David Jenkins examines the more traditional measures of performance and highlights their shortcomings as well as assessing the merits of the alternative approaches that are currently available. The book concludes with a step-by-step guide to reviewing the effectiveness of your organisation's existing systems for measuring performance and identifying ways of improving them.
