\"In this groundbreaking account of an energy revolution in the making, award-winning science writer Richard Martin introduces us to thorium, a radioactive element and alternative nuclear fuel that is far safer, cleaner, and more abundant than uranium. At the dawn of the Atomic Age, thorium and uranium seemed to be in close competition as the fuel of the future. Uranium, with its ability to undergo fission and produce explosive material for atomic weapons, won out over its more pacific sister element, relegating thorium to the dustbin of science. Now, as we grapple with the perils of nuclear energy and rogue atomic weapons and mankind confronts the specter of global climate change, thorium is reemerging as the overlooked energy source that can wean us off our fossil-fuel addiction and avert the risk of nuclear meltdown\"-- Provided by publisher.

This paper illustrates the origin, mission, organization and main activities of the Interdivisional Group of Separation Science (Gruppo Interdivisionale di Scienza delle Separazioni, GISS) of the Italian Chemical Society in occasion of the twentieth anniversary of this organization, whose mission is to promote and disseminate knowledge on all aspects of separation science and to facilitate strong peer-to-peer relationships. GISS originates from a discussion group, also belonging to the Italian Chemical Society (SCI), having similar finality and the same promoter (the Italian pioneer of Chromatography Prof. Arnaldo Liberti), but less extended scientific interests than the GISS, since it was mainly focused on liquid and gas chromatography. The interests of the GISS span theoretical and practical aspects of separation science and cover all key topics requiring high-performance separation techniques to carry out advanced investigations and/or solve challenging analytical problems. The panoramic view of the GISS includes a synthetic review of the main activities carried out since its foundation, which comprises fast-track discussion meetings, participation, promotion and/or organization of national and international congresses, sponsorship of participation grants for young trainees and Ph.D. students, recognition of scientists who have made and continue to make an outstanding contribution to separation science, as well as young scientists who have evidenced their attitude to carry out significant studies in the field of separation science.

\"The idea that the three branches of U.S. government are equal in power is taught in classrooms, proclaimed by politicians, and referenced in the media. But, as David Siemers shows, that idea is a myth, neither intended by the Founders nor true in practice. Siemers explains how adherence to this myth normalizes a politics of gridlock, in which the action of any branch can be checked by the reaction of any other. The Founders, however, envisioned a separation of functions rather than a separation of powers. Siemers argues that this view needs to replace our current view, so that the goals set out in the Constitution's Preamble may be better achieved\"-- Provided by publisher.

The aim of the book is to provide an understanding of the current science underpinning Carbon Capture and Sequestration (CCS) and to provide students and interested researchers with sufficient background on the basics of Chemical Engineering, Material Science, and Geology that they can understand the current state of the art of the research in the field of CCS. In addition, the book provides a comprehensive discussion of the impact of CCS on the energy landscape, society, and climate as these topics govern the success of the science being done in this field.

\"This book examines how the constitutional requirements of the lawmaking process, combined with the factional divisions within parties, affect U.S. representatives' decisions about how to distribute power among themselves. The incorporation of the presidential, senatorial, and House factions in the analysis of House rule making marks an important departure from previous theories, which analyze the House as an institution that makes laws in isolation. This book argues that, by constitutional design, the success of the House in passing legislation is highly contingent on the actions of the Senate and the president; and therefore, also by constitutional design, House members must anticipate such actions when they design their rules. An examination of major rule changes from 1879 to 2013 finds that changes in the preferences of constitutional actors outside the House, as well as the political alignment of these political actors vis-a-vis House factions, are crucial for predicting the timing and directionality of rule changes\"-- Provided by publisher.

Field-flow fractionation (FFF) is a family of single-phase separative techniques exploited to gently separate and characterize nano- and microsystems in suspension. These techniques cover an extremely wide dynamic range and are able to separate analytes in an interval between a few nm to 100 µm size-wise (over 15 orders of magnitude mass-wise). They are flexible in terms of mobile phase and can separate the analytes in native conditions, preserving their original structures/properties as much as possible. Molecular biology is the branch of biology that studies the molecular basis of biological activity, while biotechnology deals with the technological applications of biology. The areas where biotechnologies are required include industrial, agri-food, environmental, and pharmaceutical. Many species of biological interest belong to the operational range of FFF techniques, and their application to the analysis of such samples has steadily grown in the last 30 years. This work aims to summarize the main features, milestones, and results provided by the application of FFF in the field of molecular biology and biotechnology, with a focus on the years from 2000 to 2022. After a theoretical background overview of FFF and its methodologies, the results are reported based on the nature of the samples analyzed.

\"Economic development requires secure contract enforcement and stable property rights. Normal majority-rule politics, such as bargaining over distributive and monetary policies, generate instability and frequently undermine economic development. Above Politics argues that bureaucracies can contribute to stability and economic development, but only if they are insulated from unstable politics. A separation-of-powers stalemate creates the conditions for bureaucratic autonomy. But what keeps delegated bureaucrats from being more abusive as they become more autonomous? One answer is the negotiation of long-term, cooperative relationships - that (when successful) typically bind subordinates to provide more effort in exchange for autonomy. Even more compelling is professionalism, which embeds its professional practitioners in professional norms and culture, and incidentally mitigates corruption. Financial examples are provided throughout the book, which ends with an analysis of the role played by professionalized bureaucracies during the Great Recession\"-- Provided by publisher.

This book is a result of more than 20 years research on Simulated Moving Bed (SMB) processes at the Laboratory of Separation and Reaction Engineering (LSRE) and teaching at undergraduate level at the Department of Chemical Engineering (ChE), Faculty of Engineering of University of Porto (FEUP), graduate courses at Technical University (TU) Eindhoven and TU Delft, and an in-house course for Companhia Petroquímica do Nordeste (COPENE) (now Brazchem) and Petrogal. I graduated in ChE at University of Porto (U. Porto) in 1968, having never heard about SMB during those years. I heard about PAREX (and other Sorbex processes) in Nancy during my thesis work (1970e1973) with P. Le Goff and D. Tondeur. I found the idea of SMBdturning fixed-bed operation into continuous processesda bright one. After my African endeavors (teaching at the University of Luanda in Angola and military service there), I landed again at FEUP in August 1976 as an Assistant Professor. An optional course on Petroleum Refining for Chemical Engineering (ChE) was offered to undergraduate students given by Lopes Vaz from Petrogal. He was working in Lisbon but coming to Porto every Saturday morning to teach that course. I asked permission to attend. Lopes Vaz was a very good lecturer. It was an opportunity to learn details of the PAREX unit existing in the aromatics plant in the Refinery of Petrogal in Matosinhos. After the Revolution of April 1974, FEUP began offering evening courses allowing people with a “technical engineer” degree to get a diploma of Chemical Engineering (ChE) from U. Porto by following an additional two-year program. One of my students at that time was Soares Mota working for Petrogal and taking care of the PAREX unit. In 1978, I organized my first NATO Advanced Study Institute (ASI) on “Percolation Processes: Theory and Applications.” One of the lecturers I invited was D. Broughton from UOP (one of the inventors of SMB). He could not come, but instead A. De Rosset lectured in that ASI. I had the opportunity to travel to Des Plaines (Illinois) to visit Universal Oil Products (UOP) and meet D. Broughton at lunch. It was a business trip that I remember because I met some leaders in the Adsorption area (Vermeulen and Klein from University of California (UC) Berkeley, Wankat from Purdue, etc.). In 1984, an opportunity arose for funding to work on PAREX and ISOMAR processes when Veiga Sim~ao was Minister of Industry and Energy (MIE). He launched some Contracts for Industrial Development (CDIs) and I took the initiative of encouraging several engineers from Petrogal to join that initiative. The funding was supposed to be equivalent to 100,000 euro, but when the MIE came to Porto for the signing ceremony it seems he decided not to sign that CDI. I just found those documents while cleaning my office.

\"This exhaustively researched and deftly written book offers a first-hand view of the inner workings of the Canadian federal government, with a particular focus on the interplay between the Prime Minister's Office, the Privy Council Office, the federal cabinet, and the role backbench MPs, and parliamentary committees. Brodie argues that the various workings of the PMO, PCO, the cabinet, parliamentary committees, and the role of backbench MPs puts a lie to the proposition that the prime minister has evolved into the role of a dictator of sorts with unchecked control over the levers of political power. He offers a much-needed corrective to the dominant thinking that a Canadian prime minister holds power without limits, approaching unchecked domination over party, caucus, cabinet, Parliament, the public service, and the policy agenda. In Brodie's view, the prime minister is not a tyrant. There are effective checks on executive power. The golden age of Parliament and the backbencher is probably now. The author's contribution is that of a former insider, someone who worked at the centre and witnessed the circumstances, many of them institutional in character, that constrain the prime minister. The book calls for sober second thought about many of the proposals for reform.\"-- Provided by publisher.

Nanoplastic pollution is increasing worldwide and poses a threat to humans, animals, and ecological systems. High-throughput, reliable methods for the isolation and separation of NMPs from drinking water, wastewater, or environmental bodies of water are of interest. We investigated iron oxide nanoparticles (IONPs) with hydrophobic coatings to magnetize plastic particulate waste for removal. We produced and tested IONPs synthesized using air-free conditions and in atmospheric air, coated with several polydimethylsiloxane (PDMS)-based hydrophobic coatings. Particles were characterized with scanning electron microscopy (SEM), transmission electron microscopy (TEM), superconducting quantum interference device (SQUID) magnetometry, dynamic light scattering (DLS), X-ray diffraction (XRD) and zeta potential. The IONPs synthesized in air contained a higher percentage of the magnetic spinel phase and stronger magnetization. Binding and recovery of NMPs from both salt and freshwater samples was demonstrated. Specifically, we were able to remove 100% of particles in a range of sizes, from 2–5 mm, and nearly 90% of nanoplastic particles with a size range from 100 nm to 1000 nm using a simple 2-inch permanent NdFeB magnet. Magnetization of NMPs using IONPs is a viable method for separation from water samples for quantification, characterization, and purification and remediation of water.
