Letter to Elizabeth Rees about Distant Family
No full textLetter addressed to Elizabeth Rees, but because the last pages of this letter were lost there is no way of telling who it is from. The letter states that the author’s nephew is recovering from the swelling of his limbs and is expected to be okay. The author’s cousin Thomas will be visiting soon along with the rest of his family. Then the author continues to speak of the different marriages that have been occurring locally. This is one item from the Rees Family Correspondence Collection, which includes many letters between family members in Oregon and Ohio
Letter to a Brother of the Rees Family about Politics
No full textLetter addressed to a brother of the Rees family, but neither the author of the letter nor who the letter is to be mentioned. The letter talks about local gossip in Butteville. Then the letter cuts off and switches from March to December and talks about the Presidential candidates for 1876. It was a close race between Samuel J. Tilden and Rutherford B. Hayes, with Hayes winning the election. The author of this letter strong supports the Federalist views while talking about politics during this time. This is one item from the Rees Family Correspondence Collection, which includes many letters between family members in Oregon and Ohio
Dan Rees: Think Local, Act Global [Curatorial Project]
No full textDan Rees engages with a tradition of conceptual art making, in which familiar tropes and genres – monochromes, abstracts, ready-mades – are quietly unhinged and recuperated as strategies for production. The exhibition’s central series of Artex Paintings revive a decorative ceiling pattern, popular in British working class homes during the 1970s. Creating this type of plasterwork, once a skilled manual job, has now been rendered all but redundant as the material fell out of fashion during the late 1980s. Rees’ methodology is driven through both a recognition of the steady disappearance of the working class over recent decades and the overwriting of much of its history, as much of the disappearance of artex as a decorative mean itself. Within Rees’ paintings, distinctive shell-like patterns are combed through energetically coloured fields. Incidental manifestations within the fluid oil register against the formal exercise of combing, which both obliterates and transforms the painted surface beneath.
Devoid of saturated images or commercial slogans, the impersonal forms of Rees’ Trivision Billboards punctuate the exhibition. With their industrial and austere presence, they simulate or disguise themselves as minimalist sculptures. Placed variously on the walls and floors of the gallery spaces, their repetition suggests how they might be ordered in manifold sizes and formations. However, while minimalist objects traditionally asked to be considered as materials without reference to an outside reality, Rees undermines this logic by presenting a mechanism intended to broadcast information.
Similarly, the Artex Paintings could be understood as a deliberate subversion of abstract expressionism’s themes, in which gestural spontaneity has been rendered via the methodical repetitions of a builder’s tool. In Rees’ continued examination of reproduction and repetition, the work enters the format of a series, removing it from wry conceptual exercise.
While the abstract works of the Artex Paintings and the minimalism of the billboards do not project the artist’s ideology directly, this is more clearly revealed in Rees’ video work Road Back To Relevance. Produced in collaboration with an advertising strategist and designer, the slide-show questions of how various modes of social engagement can remain relevant today by charting the course of a specific solidarity campaign, started in the 1980s between Wales and Nicaragua. While the visual tone of this work might suggest a need for such solidarity campaigns to modernise in order to reach a wider audience, the conclusion appears to be the opposite. Rather, the work points to the relevance of maintaining an inclusive and personal approach towards creating new connections between people, one that goes beyond issues of technology and dispersion.

On the future: prospects for humanity/ Martin Rees, with a new preface by the author.
No full textDescription based upon print version of record.Includes bibliographical references and index.A provocative and inspiring look at the future of humanity and science from world-renowned scientist and bestselling author Martin ReesHumanity has reached a critical moment. Our world is unsettled and rapidly changing, and we face existential risks over the next century. Various outcomes--good and bad--are possible. Yet our approach to the future is characterized by short-term thinking, polarizing debates, alarmist rhetoric, and pessimism. In this short, exhilarating book, renowned scientist and bestselling author Martin Rees argues that humanity's prospects depend on our taking a very different approach to planning for tomorrow.The future of humanity is bound to the future of science and hinges on how successfully we harness technological advances to address our challenges. If we are to use science to solve our problems while avoiding its dystopian risks, we must think rationally, globally, collectively, and optimistically about the long term. Advances in biotechnology, cybertechnology, robotics, and artificial intelligence--if pursued and applied wisely--could empower us to boost the developing and developed world and overcome the threats humanity faces on Earth, from climate change to nuclear war. At the same time, further advances in space science will allow humans to explore the solar system and beyond with robots and AI. But there is no "Plan B" for Earth--no viable alternative within reach if we do not care for our home planet.Rich with fascinating insights into cutting-edge science and technology, this accessible book will captivate anyone who wants to understand the critical issues that will define the future of humanity on Earth and beyond.Cover -- Contents -- Preface to the Paperback Edition -- Introduction -- 1.

Alan Wilson - Contributions to Research on Population and Migration
No full textThis article reviews Alan Wilson's research on population and migration in the 1970s and the 2010s, which supplements his principal contribution - mathematical modelling of urban and regional systems. In the 1970s, drawing on input-output models of economies and working with Philip Rees, Wilson established the accounting basis for Andrei Rogers' multi-regional projection model, adding international migration. Innovative methods were developed to complete demographic accounts, where there were data gaps. In the 2010s, working with Adam Dennett, Wilson systematized methods for estimating migration flows between regions in Europe, employing his family of spatial interaction models. The key aim of both research strands was to ensure that no information was ignored to ensure consistency in population and migration models. The influence of Wilson's contributions to research on population and migration is traced through a survey of subsequent research

Selective electrochemical extraction of REEs from NdFeB magnet waste at room temperature
No full textNdFeB magnet waste is one of the important secondary resources from which rare-earth elements (REEs) can be recovered. Herein we present an electrochemical route to selectively extract REEs from the magnet waste at room temperature. First, the magnet waste was partially leached with HCl. The partial leachate along with undissolved magnet waste was taken in the anolyte side of a two compartment reactor separated by an anion exchange membrane whereas the catholyte consisted of sodium chloride solution. The Fe(ii) present in the leachate was oxidized and precipitated as Fe(OH)3 while more than 95% of REEs were extracted into the solution. Subsequently, oxalic acid was used to selectively precipitate REEs as rare-earth oxalates. Hydrochloric acid liberated during the oxalic acid precipitation process could be directly reused in the partial leaching step. Sodium chloride was the only chemical consumed during the electrolysis. The effect of the NaCl concentration in the anolyte and catholyte on the extraction of metals was investigated. From magnet waste to rare-earth oxides, the developed recycling process is environmentally friendly and consumes only electricity, NaCl and oxalic acid.Accepted Author Manuscript(OLD) MSE-
Green index in semigroups : generators, presentations and automatic structures
No full textThe Green index of a subsemigroup T of a semigroup S is given by counting strong orbits in the complement S n T under the natural actions of T on S via right and left multiplication. This partitions the complement S nT into T-relative H -classes, in the sense of Wallace, and with each such class there is a naturally associated group called the relative Schützenberger group. If the Rees index ΙS n TΙ is finite, T also has finite Green index in S. If S is a group and T a subgroup then T has finite Green index in S if and only if it has finite group index in S. Thus Green index provides a common generalisation of Rees index and group index. We prove a rewriting theorem which shows how generating sets for S may be used to obtain generating sets for T and the Schützenberger groups, and vice versa. We also give a method for constructing a presentation for S from given presentations of T and the Schützenberger groups. These results are then used to show that several important properties are preserved when passing to finite Green index subsemigroups or extensions, including: finite generation, solubility of the word problem, growth type, automaticity (for subsemigroups), finite presentability (for extensions) and finite Malcev presentability (in the case of group-embeddable semigroups).Peer reviewe
