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.

Human rights trauma and the mental health of West Papuan refugees resettled in Australia
No full textThis article finds that West Papuan refugees resettled in Australia report a wide range of premigration potentially traumatic events (PTEs) including human rights violations as well as symptoms of PTSD and distress.Abstract Objectives: To document the extent and nature of human rights violations and other traumatic events reported by West Papuan refugees resettled in Australia and to assess trauma-related psychological disorders, distress and disability.Design and setting: Australian-based sample, mixed-methods design with 44 participants, conducted in Australia between October 2007 and November 2010 in communities in North Queensland and Melbourne.Participants: West Papuan refugees aged 18 years and over (88% response rate).Main outcome measures: Post-traumatic stress disorder (PTSD) symptoms (Harvard Trauma Questionnaire) and premigration potentially traumatic events (PTEs), psychological distress (Kessler Psychological Distress Scale [K10]), post-migration living difficulties, days out of role.Results: Of the 44 West Papuan refugees, 40 reported one or more PTE, including inability to access medical care for family (40), lack of food and water (39) and lack of access to medical treatment (38). The most frequent postmigration stressors were separation from and worries about family members remaining in West Papua (43) and being unable to return home in an emergency because of ongoing conflict (41). Twenty-six participants reached a lower threshold for PTSD symptoms of 2.0, and 13 reached the clinical threshold of 2.5. Fourteen reported severe psychological distress.Conclusions: West Papuan refugees resettled in Australia report a wide range of premigration PTEs including human rights violations, as well as symptoms of PTSD and distress. The data add to concerns about the state of human rights and mental health among West Papuans.Authored by Susan Rees, Derrick M Silove, Kuowei Tay and Moses Kareth
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.

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-
CYCLOPӔDIA; OR, UNIVERSAL DICTIONARY OF Arts, Sciences, and Literature: PLATES, VOL. VI, ANCIENT AND MODERN ATLAS

Ex-ante LCA of a hydrometallurgical route using weak acid for recycling of REEs from EOL HDD’s NdFeB permanent magnet
No full textThe rare-earth elements (REEs) are Europe’s most critical raw-materials group due to the high supply dependency on the Chinese REEs near-monopoly. The NdFeB permanent magnet in EOL hard disk drivers (HDDs) is an actual source of REEs. However, REEs recycling routes are still under development. Hydrometallurgical routes are attractive because they are versatile, but concerns arise regarding their chemical consumption and the implication to the environment. An ex-ante environmental analysis supports the launch and consolidation of the route in an environmentally sound manner. This work aims to identify the environmental hotspots of a theoretical hydrometallurgical recycling route for REEs, which uses acetic acid for leaching and oxalic acid for precipitation. The route also allows chemical recycling through a loop within it. The ultimate goal is to draw recommendations toward improving the environmental profile of the technology before it gets implemented. The evaluation is carried using the Life Cycle Assessment (LCA) methodology according to a dedicated framework for ex-ante analysis, including upscaling. The analysis highlights as hotspots the oxalic acid in the precipitation stage and the direct dust emissions and its treatment in the fragmentation of HDDs. Moreover, results indicate that acetic acid regeneration within the system is more burdensome than use the chemical produced from raw materials. The premature assessment also indicates that the environmental profile of the emerging technology is potentially inferior to the established primary production. A limitation of the model arises from the economic allocation for multifunctional processes due to the approach developed to stipulate the price of some co-products. Overall, the uncertainties carried with the ex-ante LCA prevent any assertive declaration regarding the recycling route’s environmental performance. However, the exercise contributes to the problem-solution space. It gives directions to the next steps: better data collection for the RE recovery phase, less dust production in the fragmentation phase, other means for precipitation of REEs, and variation in the leaching solid-liquid ratio.VALOMAGCircular EconomyIndustrial Ecolog
