Effect of Sulphide on Enhanced Biological Phosphorus Removal

The enhanced biological removal of phosphorus (EBPR) is a popular process due to high removal efficiency, low operational costs, and the possibility of phosphorus recovery. Nevertheless, the stability of the EBPR depends on different factors such as: temperature, pH, and the presence of toxic compounds. While extensive studies have researched the effects of temperature and pH on EBPR systems, little is known about the effects of different toxic compounds on EBPR. For example, sulphide has shown to inhibit different microbial activities in the WWTP, but the knowledge about its effects on EBPR is limited. Whereas the sulphide generated in the sewage can cause a shock effect on EBPR, the continuously exposure to sulphide potentially generated in WWTP can cause the acclimatization and adaptation of the biomass.This research suggests that sulphate reducing bacteria can proliferate in WWTP, as they are reversibly inhibited by the recirculation of sludge through anaerobic-anoxic-oxic conditions. The research enhances the understanding of the effect of sulphide on the anaerobic-oxic metabolism of PAO. It suggests that the filamentous bacteria Thiothrix caldifontis could play an important role in the biological removal of phosphorus. It questions the ability of PAO to generate energy from nitrate respiration and its use for the anoxic phosphorus uptake. Thus, the results obtained in this research can be used to understand the stability of the EBPR process under anaerobic-anoxic-oxic conditions, especially when exposed to the presence of sulphide.

Negotiating the Emotional Challenges of Conducting Deeply Personal Research in Health

Public health researchers and clinicians regularly work with people who have suffered physical and mental trauma. Knowing how to conduct a study or treat a patient while navigating deep emotional issues requires special skills and overall awareness of how trauma can impact the process and outcomes of participating in research and/or receiving health care. a This book presents a diverse array of case examples from scholars of health-related topics, focusing on biographical narrative as a window into understanding key needs in trauma informed scholarship and medicine. Exploring stories from people of varied backgrounds, experiences, and contexts can help professionals within and beyond the academic research and clinical care spheres create rewarding experiences for patients.a Negotiating the Emotional Challenges of Conducting Deeply Personal Research in Health will be of interest to public health practitioners, educators and researchers as well as students.

Linear and Switch-Mode RF Power Amplifiers

RF power amplifiers are implemented in communication, semiconductor wafer processing, magnetic resonance imaging (MRI), and radar systems to produce RF signal with the desired characteristics to perform several critical tasks in the entire system. They can be designed to operate in linear or switch-mode, depending on the specific application. This book explores the design and implementation methods for both linear and switch-mode amplifiers with real world engineering problems. The text discusses phased controlled switch-mode amplifiers and distortion and modulation effects in RF amplifiers. It illustrates the interface and integration of components and sub-systems for RF amplifiers. The material is further reinforced with MATLAB design files.

Ethics and Psychology

This highly original book explores the idea and potential of psychology in the context of ethical theory, and the idea of ethics in the context of psychology. In so doing, it not only interrogates how we come to understand ethics and notions of right behaviour, but also questions the discipline of psychology and how it functions in the 21st century. Neill turns psychology inside out, controversially suggesting that psychology no longer exists as we know it. He proposes a rebirth of psychology based on an intricate and detailed examination of who we really are, and how we come to structure this idea of ourselves. Taking the idea of ethics seriously, Neill allows us to see psychology in a totally new light, addressing key points, such as: The inadequacy of psychology to address the question of ethics throughout history. Why thinking through the question of ethics necessarily brings us into confrontation with a question of psychology. What we actually do when we do psychology and how, via a serious consideration of ethics we might do this differently and better. Ethics and Psychology presents readers with a new and potentially productive understanding of both ethics and psychology and will appeal to anyone active within and critically engaged with the field.

Aesthetics

First published in 1970. What is a work of art? What is the status of things in pictures and books? How are we to distinguish and ascertain the meaning of a literary work at various levels? This book is intended both to introduce the reader to classic philosophical accounts of art and beauty, and to bring out the significance for aesthetics of recent developments in philosophy.

Eurocentrism at the Margins

Eurocentrism remains a prevailing feature of Western-dominated social scientific perspectives, tending to ignore alternative views originating outside the West and thus maintaining a form of scholarly hegemony. As such, there is an urgent need to reconsider Eurocentrism in social science, to ask whether it constitutes an obstacle to understanding social problems and whether it is possible to go beyond Eurocentrism in the construction of reliable, more universal knowledge. At the same time, certain questions persist, particularly with regard to the extent to which recent revisionist challenges have really contributed to the surmounting of Eurocentric domination, and whether the constant repetition of the concept serves to reinforce it. This book engages with the central problems of Eurocentrism in the social sciences, bringing together the work of scholars from around the world to offer a critique of this perspective from both European and non-European positions, thus shedding light on the binaries that often come into being in debates in this field. Thematically organised and addressing a range of questions, including Eurocentrism in historical studies, in the understanding of religion and civilisation and in the study of international relations, as well as in the institutionalisation and professionalisation of research and discourses on modernisation in the Middle East, Eurocentrism at the Margins will appeal to scholars with interests in knowledge production and circulation, and Eurocentrism and post-colonialism in the social sciences.

Radical Right-Wing Populist Parties in Western Europe

Radical right-wing populist parties, such as Geert Wilders’ Party for Freedom, Marine Le Pen’s National Front or Nigel Farage’s UKIP, are becoming increasingly influential in Western European democracies. Their electoral support is growing, their impact on policy-making is substantial, and in recent years several radical right-wing populist parties have assumed office or supported minority governments. Are these developments the cause and/or consequence of the mainstreaming of radical right-wing populist parties? Have radical right-wing populist parties expanded their issue profiles, moderated their policy positions, toned down their anti-establishment rhetoric and shed their extreme right reputations to attract more voters and/or become coalition partners? This timely book answers these questions on the basis of both comparative research and a wide range of case studies, covering Austria, Belgium, Denmark, Finland, France, the Netherlands, Norway, Switzerland, and the United Kingdom. Analysing the extent to which radical right-wing populist parties have become part of mainstream politics, as well as the factors and conditions which facilitate this trend, this book is essential reading for students and scholars working in European politics, in addition to anyone interested in party politics and current affairs more generally.

Globalization of Knowledge in the Post-Antique Mediterranean, 700-1500

The contributions to this volume enter into a dialogue about the routes, modes and institutions that transferred and transformed knowledge across the late antique Mediterranean and the Persian Gulf. Each contribution not only presents a different case study but also investigates a different type of question, ranging from how history-writing drew on cross-culturally constructed stories and shared sets of skills and values, to how an ancient warlord was transformed into the iconic hero of a newly created monotheistic religion. Between these two poles, the emergence of a new, knowledge-related, but market-based profession in Baghdad is discussed, alongside the long-distance transfer of texts, doctrines and values within a religious minority community from the shores of the Caspian Sea to the mountains of the southern Arabian Peninsula. The authors also investigate the outsourcing of military units and skills across religious and political boundaries, the construction of cross-cultural knowledge of the balance through networks of scholars, patrons, merchants and craftsmen, as well as differences in linguistic and pharmaceutical practices in mixed cultural environments for shared corpora of texts, drugs and plants.
