This report contains the Proceedings of the 17th Specialists' Meeting on the Chemistry and Technology of Actinide Elements, which was held at Research Reactor Institute, Kyoto University, on February 15, 2012. This specialists' meeting has been held annually since 1994, and this is the 17th meeting for the fiscal year 2011. The accident of Fukushima Daiich Nuclear Power Plant, which occurred on March 11, 2011, showed the presence of defect in Japanese past approach to keep nuclear system safe. There is the need to improve existing technological and operational problems, as well as regulatory problems, but we should be aware of the significance of recovering social trust and peoples' peace of mind with the nuclear power. It should be noted that public's anxiety on the backend issue of nuclear system is remarkably big, and thus we must try to provide an understandable solution to them. In this meeting, we dealt with actinide chemistry and technology, which are related to the advanced nuclear fuel cycle development and the disposal of the HLW or TRU wastes. This is because, in the backend of the nuclear system, Actinide and TRU elements have substantial importance, because all of reprocessing, geologic disposal, and partitioning and transmutation depend significantly on the chemistry and technology of Actinides. Therefore, we have continued discussion and information exchange on the Actinide issues over 16 years, and this year's 17th meeting had a special meaning as the first one after the accident. In this context in this 17th meeting, we tried to return to the fundamentals of molten salt chemistry, which is the base of the dry reprocessing development. In addition, in order to expand our attitude by crossing over the fence of nuclear society, we tried to explore the potential of the adoption of molten salt chemistry to the general industry. This was a small new attempt in compliance with the recent tendency to nuclear power reduction in

This proposal supported Chemistry Symposia at the 2011 American Association for the Advancement of Science (AAAS) Meeting in Washington, DC February 17-21, 2011. The Chemistry Section of AAAS presented an unusually strong set of symposia for the 2011 AAAS meeting to help celebrate the 2011 International Year of Chemistry. The AAAS meeting provided an unusual opportunity to convey the excitement and importance of chemistry to a very broad audience and allowed access to a large contingent of the scientific press. Excellent suggestions for symposia were received from AAAS Chemistry Fellows and from the chairs of the American Chemical Society Technical Divisions. The AAAS Chemistry executive committee selected topics that would have wide appeal to scientists, the public, and the press for formal proposals of symposia. The symposia proposals were peer reviewed by AAAS. The Chemistry Section made a strong case to the program selection committee for approval of the chemistry symposia and 6 were approved for the 2011 annual meeting. The titles of the approved symposia were: (1) Powering the Planet: Generation of Clean Fuels from Sunlight and Water, (2) Biological Role and Consequences of Intrinsic Protein Disorder, (3) Chemically Speaking: How Organisms Talk to Each Other, (4) Molecular Self-Assembly and Artificial Molecular Machines, (5) Frontiers in Organic Materials for Information Processing, Energy and Sensors, and (6) Celebrating Marie Curie's 100th Anniversary of Her Nobel Prize in Chemistry. The Chemistry Section of AAAS is provided with funds to support only 1-2 symposia a year. Because of the much greater number of symposia approved in conjunction with observance of the 2011 International Year of Chemistry, additional support was sought from DOE to help support the 30 invited speakers and 8 symposia moderators/organizers. Support for the symposia provided the opportunity to highlight the excitement of current chemical research, to educate the public about

The success or failure of an implant material in the body depends on a complex interaction between a synthetic 'foreign body' and the 'host tissue'. These interactions occur at many levels from the sub-microscopic level, where subtle changes in the surface physio-chemistry can substantially alter the nature of the biomaterial-host tissue interface, through the microscopical level (e.g. sensitivity to surface topography) to the macrostructural level (e.g. dependence on scaffold porosity). Thus the factors that control these responses are not only biologically determined but also mechanically, physically and chemically mediated, although identifying where one starts and the other finishes can be difficult. Design of a successful medical device has therefore to call on expertise within a wide range of disciplines. In terms of both investigating the basic science behind the factors which orchestrate a biological response and developing research tools that enable study of these responses. However, a medical device must also meet the economic and practical demands of health care professionals who will ultimately be using it in the clinic. Bone graft substitute materials are used in orthopaedics as an alternative or adjunct to autografting, a practice where the patient 'donates' bone from a healthy site to aid bone repair at a damaged or diseased site. These materials are used in a wide range of procedures from total hip revision to spinal fusion and their evolution over the last 10 years illustrates how an interdisciplinary approach has benefited their development and may lead to further innovation in the future.

The Croatian Chemical Society was established in 1926 and has developed over the decades into a society that actively supports all chemical activities in Croatia. The Society has eight divisions, the youngest of which, the Division of Medicinal and Pharmaceutical Chemistry, was established in 2012 and immediately became a member of the European Federation of Medicinal Chemistry (EFMC). The mission of the Medicinal and Pharmaceutical Chemistry Division is the promotion and development of scientific, professional, and educational activities within the medicinal chemistry community in Croatia, as well as to build partnerships and collaborations with other primarily EU-based medicinal chemistry societies. In Croatia, medicinal chemistry research is ongoing at several institutes, including the University of Zagreb (Faculty of Science, Faculty of Pharmacy and Biochemistry, and Faculty of Chemical Engineering and Technology), national institutes of science (Ruđer Bošković Institute), and private-sector drug discovery companies (CRO Fidelta Ltd.). In order to effectively exchange knowledge, ideas, and scientific results, Croatian medicinal chemists meet twice annually. © 2018 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

Little isd known about how meals are chosen for medical meetings. We surveyed the annual meeting planners for 20 major specialty societies. Thirteen (65%) responded; all were currently planning their next meeting. Attendance in 2000 was reported at 113,477 physicians, with 2 million planned meals and snacks. No physician was named as responsible for food choices; the meeting planner and staff were primarily responsible for deciding what food to serve, excluding exhibit halls. Twelve (92%) respondents rated "available budget" as the most important factor. "Nutritional guidelines" were rated "very important" by eight of 13 (63%). However, no specific nutritional guidelines could be identified by any planner. All respondents indicated that members would attend a meeting if "healthy" food were the only option. For 2000, 100% of respondents indicated that for each lunch and for each dinner, a dessert had been included. No annual meeting and no planned 2001 meeting excluded potato chips, snack mixes, or candies at breaks; soda pop was offered at each break. Most respondents (89%) relied on a concluding questionnaire about the meeting facilities to evaluate the food. Respondents reported no difference in charges for "special meals," including vegetarian and kosher meals. Physicians may be unaware that some food served at medical meetings may impair learning, with excessive calorie, fat, and carbohydrate consumption. Small changes can improve the quality of food and beverages selected, without increased cost, and provide choices that conform to national nutritional guidelines. Medical meetings should serve flavorful, healthful food.

The use of iodinated contrast media has grown in popularity in the past two decades, but relatively little attention has been paid to the possible interferential effects of contrast media on laboratory test results. Herein, we investigate medical contrast media interference with routine chemistry results obtained by three automated chemistry analyzers. Ten levels of pooled serum were used in the study. Two types of medical contrast media [Iopamiro (iopamidol) and Omnipaque (iohexol)] were evaluated. To evaluate the dose-dependent effects of the contrast media, iopamidol and iohexol were spiked separately into aliquots of serum for final concentrations of 1.8%, 3.6%, 5.5%, 7.3%, and 9.1%. The 28 analytes included in the routine chemistry panel were measured by using Hitachi 7600, AU5800, and Cobas c702 analyzers. We calculated the delta percentage difference (DPD) between the samples and the control, and examined dose-dependent trends. When the mean DPD values were compared with the reference cut-off criteria, the only uniformly interferential effect observed for all analyzers was in total protein with iopamidol. Two additional analytes that showed trends toward interferential effects only in few analyzers and exceeded the limits of the allowable error were the serum iron and the total CO 2 . The other combinations of analyzer and contrast showed no consistent dose-dependent propensity for change in any analyte level. Our study suggests that many of the analytes included in routine chemistry results, except total protein and serum iron, are not significantly affected by iopamidol and iohexol. These results suggest that it would be beneficial to apply a flexible medical evaluation process for patients requiring both laboratory tests and imaging studies, minimizing the need for strict regulations for sequential tests.

High-Relaxivity MRI Contrast Agents: Where Coordination Chemistry Meets Medical Imaging

Energy Technology Data Exchange (ETDEWEB)

Werner, Eric J.; Datta, Ankona; Jocher, Christoph J.; Raymond, Kenneth N.

2008-01-15

The desire to improve and expand the scope of clinical magnetic resonance imaging (MRI) has prompted the search for contrast agents of higher efficiency. The development of better agents requires consideration of the fundamental coordination chemistry of the gadolinium(III) ion and the parameters that affect its efficacy as a proton relaxation agent. In optimizing each parameter, other practical issues such as solubility and in vivo toxicity must also be addressed, making the attainment of safe, high-relaxivity agents a challenging goal. Here we present recent advances in the field, with an emphasis on the hydroxypyridinone family of Gd{sup III} chelates.

A specialists' meeting was held at JRC-Ispra from 15 to 17 January 1990 to review the current understanding of fission-product chemistry during severe accidents in light water reactors. Discussions focussed on the important chemical phenomena that could occur across the wide range of conditions of a damaged nuclear plant. Recommendations for future chemistry work were made covering the following areas: (a) fuel degradation and fission-product release, (b) transport and attenuation processes in the reactor coolant system, (c) containment chemistry (iodine behaviour and core-concrete interactions).

The contribution of patients' non-medical characteristics to individual physicians' decision-making has attracted considerable attention, but little information is available on this topic in the context of collective decision-making. Medical decision-making at cancer centres is currently carried out using a collective approach, at MultiDisciplinary Team (MDT) meetings. The aim of this study was to determine how patients' non-medical characteristics are presented at MDT meetings and how this information may affect the team's final medical decisions. Observations were conducted at a French Cancer Centre during MDT meetings at which non-standard cases involving some uncertainty were discussed from March to May 2014. Physicians' verbal statements and predefined contextual parameters were collected with a non-participant observational approach. Non numerical data collected in the form of open notes were then coded for quantitative analysis. Univariate and multivariate statistical analyses were performed. In the final sample of patients' records included and discussed (N = 290), non-medical characteristics were mentioned in 32.8% (n = 95) of the cases. These characteristics corresponded to demographics in 22.8% (n = 66) of the cases, psychological data in 11.7% (n = 34), and relational data in 6.2% (n = 18). The patient's age and his/her "likeability" were the most frequently mentioned characteristics. In 17.9% of the cases discussed, the final decision was deferred: this outcome was positively associated with the patients' non-medical characteristics and with uncertainty about the outcome of the therapeutic options available. The design of the study made it difficult to draw definite cause-and-effect conclusions. The Social Representations approach suggests that patients' non-medical characteristics constitute a kind of tacit professional knowledge that may be frequently mobilised in physicians' everyday professional practice. The links observed between patients

After a short introduction on the development of the medieval universities at Pécs, Obuda, and Pozsony, and mentioning those who lectured in medicine in Hungary, the authors emphasise that modern chemistry was born during the 16th and 17th century. They stress the role of Paracelsus who invented iatro-chemistry, and that the first independent chairs, were founded in Germany in the beginning of 17th century at Altdorf, Marburg, Jéna, but were followed suit by Paris, when the Jardin des Plantes were erected. The first chemical textbook, the Cours de Chimie (Paris 1665), was also the work of a Frenchman, namely Nicolas Lémery (1645-1715). From the 18th century chemistry was also included in the curriculum of medical education in Hungary. Among the chairs of the newly founded medical faculty at Nagyszombat we find the chemical-botanical department in 1769. Its first professor was an Austrian physician Jakab Winterl (1773-1809), who had been a head physician at Selmecbánya, in Northern Hungary. Owing to a rash and premature publication Winterl's international reputation was unfortunately undermined in the last century by a leading German science historian, Hermann Kopp. The authors stress, however, that Winterl indeed played an important role in organizing the chemical department, and purchasing all the necessary equipment needed for up to date researches and analyses. And above all, in his Prolusiones ad chemiam saeculi decimi noni, he foresaw many forthcoming paths and discoveries of 19th century chemistry. After Winterl's retirement the department was divided into two parts. Pál Kitaibel (1757-1817) led the botanica department and János schuster (1777-1838) the other one for chemistry. Kitaibel made a name for himself by depicting Hungarian flora, but he also made discoveries in chemistry. He discovered chlore lime, before Tennant in 1795, a material which might have been used for whitening textiles. Schuster, on the other hand, introduced a system of Hungarian

Forensic chemistry is unique among chemical sciences in that its research, practice, and presentation must meet the needs of both the scientific and the legal communities. As such, forensic chemistry research is applied and derivative by nature and design, and it emphasizes metrology (the science of measurement) and validation. Forensic chemistry has moved away from its analytical roots and is incorporating a broader spectrum of chemical sciences. Existing forensic practices are being revisited as the purview of forensic chemistry extends outward from drug analysis and toxicology into such diverse areas as combustion chemistry, materials science, and pattern evidence.

Water chemistry and corrosion control of cladding and primary circuit components. Proceedings of a technical committee meeting

International Nuclear Information System (INIS)

1999-12-01

Corrosion is the principal life limiting degradation mechanism in nuclear steam supply systems, especially taking into account the trends to increase fuel burnup, thermal rate and cycle length. Primary circuit components of water cooled power reactors have an impact on Zr-based alloys behaviour due to crud (primary circuit corrosion products) formation, transport and deposition on heat transfer surfaces. Crud deposits influence water chemistry, radiation and thermal hydraulic conditions near cladding surface, and by this way-Zr-based alloy corrosion. During the last decade, significant improvements were achieved in the reduction of the corrosion and dose rates by changing the cladding material for one more resistant to corrosion or by the improvement of water chemistry conditions. However, taking into account the above mentioned tendency for heavier fuel duties, corrosion and water chemistry, control will remain a serious task to work with for nuclear power plant operators and scientists, as well as development of generally accepted corrosion model of Zr-based alloys in a water environment in a new millennium. Upon the recommendation of the International Working Group on Water Reactor Fuel Performance and Technology, water chemistry and corrosion of cladding and primary circuit components are in the focus of the IAEA activities in the area of fuel technology and performance. At present the IAEA performs two co-ordinated research projects (CRPs): on On-line High Temperature Monitoring of Water Chemistry and Corrosion (WACOL) and on Activity Transport in Primary Circuits. Two CRPs deal with hydrogen and hydride degradation of the Zr-based alloys. A state-of-the-art review entitled: 'Waterside Corrosion of Zirconium Alloys in Nuclear Power Plants' was published in 1998. Technical Committee meetings on the subject were held in 1985 (Cadarache, France), 1989 (Portland, USA), 1993 (Rez, Czech Republic). During the last few years extensive exchange of experience in

1995-10-01

Radiation chemistry is a branch of chemistry that studies chemical transformations in materials exposed to high-energy radiations. It is based on the use of ionizing radiation as the initiator or catalyst in chemical reactions. The most significant advantage of radiation chemistry lies in its ability to be used in the production and study of almost any reactive atomic and molecular species playing a part in chemical reaction, synthesis, industrial processes, or in biological systems. Over the the last few years a number of meetings have taken place, under the auspices of the IAEA, in order to evaluate recent developments in radiation chemistry as well as the trends indicated by the results obtained. Radiation chemists from different countries have participated at these meetings. The present publication, a companion to the previous publication - New Trends and Development in Radiation Chemistry, IAEA-TECDOC-527 (1989) - includes some of the important contributions presented at these meetings. It is hoped that it will provide a useful overview of current activities and of emerging trends in this field, thus promoting better understanding of potential contributions of radiation chemistry to other fields of knowledge as well as to practical applications in industry, medicine and agriculture.

Teaching biochemistry to medical students in Singapore--from organic chemistry to problem-based learning.

Science.gov (United States)

Khoo, H E

2005-07-01

The medical faculty in the National University of Singapore started in 1905 but the Chair in Biochemistry was only established in 1927. For many years the biochemistry course consisted of the teaching of the organic chemistry of substances of physiological importance, nutrition, metabolism and hormones. In 1961, clinical biochemistry was introduced and in the 1980s, genetics and molecular biology were included. By then, most of the organic chemistry content had been removed as greater emphasis was placed on clinical correlation. Laboratory classes consisted of mock glucose tolerance tests and the measurement of various enzymes. By the 1990s, students were no longer interested in such practical classes, so a bold decision was made around 1995 to remove laboratory classes from the curriculum. Unfortunately, this meant that the medical students who might have been interested in laboratory work could no longer do such work. However, the new curriculum in 1999 gave the department an opportunity to offer a laboratory course as an elective for interested students. This new curriculum adopted an integrated approach with Genetics being taught as part of Paediatrics, and a new module (Structural and Cell Biology) comprising aspects of cell biology and biochemistry was introduced. This module is currently taught by staff from Anatomy, Physiology and Biochemistry. Some biochemistry content is now incorporated into the clinical problem scenarios of problem-based learning such as jaundice, diabetes mellitus, anorexia nervosa, etc. So the evolution of teaching biochemistry to medical students in Singapore has paralleled worldwide trends and moved from the didactic teaching of organic chemistry of biomolecules to problem-based learning using clinical cases.

Proceedings of the DAE-BRNS theme meeting on recent trends in analytical chemistry: book of abstracts

International Nuclear Information System (INIS)

2012-01-01

Analytical chemistry is the branch of science that deals with the determination of the identity and concentration of various elements and compounds in different matrices including living systems. The practice of analytical chemistry as a distinct discipline possibly began in the late eighteenth century with the work of the French chemist Antoine-Laurent Lavoisier and his contemporaries. Further progress was made in the nineteenth century by scientists like Carl Fresenius and Karl Friedrich Mohr. Fresenius developed the qualitative analysis method and it formed the topic of the first textbook of analytical chemistry. He also developed the gravimetric technique. Mohr developed many laboratory analytical procedures and devices. Most of the major advances in analytical chemistry, as in many other branches of science, took place in the twentieth century after the Second World War. The demand for new and increasingly sophisticated analytical techniques for bio-medical, regulatory and strategic requirements, along with the progress in electro-mechanical instrumentation, automation and computerization, has opened up new challenges and opportunities for analytical chemists and allied scientists in the years to come.

New trends and developments in radiation chemistry

International Nuclear Information System (INIS)

1989-10-01

Radiation chemistry is a branch of chemistry that studies chemical transformations in materials exposed to high-energy radiations. It uses radiation as the initiator of chemical reactions. Practical applications of radiation chemistry today extend to many fields, including health care, food and agriculture, manufacturing, industrial pollution abatement, biotechnology and telecommunications. The important advantage of radiation chemistry lies in its ability to be used to produce, and study, almost any reactive atomic and molecular species playing a part in chemical reactions, synthesis, industrial processes, or in biological systems. The techniques are applicable to gaseous, liquid, solid, and heterogeneous systems. By combining different techniques of radiation chemistry with analytical chemistry, the reaction mechanism and kinetics of chemical reactions are studied. In November 1988 in Bologna, Italy, the IAEA convened an advisory group meeting to assess new trends and developments in radiation chemistry. The present publication includes most of the contributions presented at the meeting. Refs, figs and tabs

The 2008 Lindau Nobel Laureate Meeting: Robert Huber, Chemistry 1988. Interview by Klaus J. Korak.

Huber, Robert

2008-11-25

Robert Huber and his colleagues, Johann Deisenhofer and Hartmut Michel, elucidated the three-dimensional structure of the Rhodopseudomonas viridis photosynthetic reaction center. This membrane protein complex is a basic component of photosynthesis - a process fundamental to life on Earth - and for their work, Huber and his colleagues received the 1988 Nobel Prize in Chemistry. Because structural information is central to understanding virtually any biological process, Huber likens their discovery to "switching on the light" for scientists trying to understand photosynthesis. Huber marvels at the growth of structural biology since the time he entered the field, when crystallographers worked with hand-made instruments and primitive computers, and only "a handful" of crystallographers would meet annually in the Bavarian Alps. In the "explosion" of structural biology since his early days of research, Huber looks to the rising generation of scientists to solve the remaining mysteries in the field - such as the mechanisms that underlie protein folding. A strong proponent of science mentorship, Huber delights in meeting young researchers at the annual Nobel Laureate Meetings in Lindau, Germany. He hopes that among these young scientists is an "Einstein of biology" who, he says with a twinkle in his eye, "doesn't know it yet." The interview was conducted by JoVE co-founder Klaus J. Korak at the Lindau Nobel Laureate Meeting 2008 in Lindau, Germany.

2016-01-01

To meet the needs of the population of North Carolina, an epic transformation is under way in health care. This transformation requires that we find new ways to educate and train physicians and other health care professionals. In this commentary, we propose that the success of the Brody School of Medicine in preparing a primary care physician workforce can serve as a model for meeting the state's future physician workforce needs. Other considerations include increasing graduate medical education positions through state funding and providing incentives for medical students who stay in North Carolina. ©2016 by the North Carolina Institute of Medicine and The Duke Endowment.

The Medical School Admissions Process and Meeting the Public's Health Care Needs: Never the Twain Shall Meet?

Science.gov (United States)

Cleland, Jennifer

2017-12-19

Medical schools typically assess how good their selection process is using metrics such as students' assessment performance and the academic success of alumni on later indicators of academic ability and clinical competence, such as Royal College of Physicians or specialty board examinations. To address global issues with the maldistribution of doctors and increasing numbers of new medical school graduates choosing not to work in a clinical context requires different measurements of medical school admissions processes, like those related to graduates' career outcomes (e.g., working in underserved regions and/or working in certain specialties). This shift in focus is not straightforward. Medical education is a complex social system where, intentionally or not, medical schools focus on reproducing cultural, historical, and social norms. Simple solutions are often proposed but they are insufficient to address these complex drivers. Instead it is time to step back and think very differently about medical school admissions. In this Invited Commentary, the author proposes new solutions to address these issues, including: bringing in to the medical school selection process the perspectives of other key stakeholders; increasing collaboration and dialogue across these stakeholder groups; changing the performance metrics by which medical schools are assessed in the global education marketplace; and developing and evaluating new selection processes and tools. Medical schools must engage more reflectively and collaboratively in debates about how to align medical school admissions and meeting the health care needs of the public.

An ideal teaching program of nuclear chemistry in the undergraduate chemistry curriculum

International Nuclear Information System (INIS)

Uenak, T.

2009-01-01

It is well known that several reports on the common educational problems of nuclear chemistry have been prepared by certain groups of experts from time to time. According to very important statements in these reports, nuclear chemistry and related courses generally do not take sufficient importance in undergraduate chemistry curricula and it was generally proposed that nuclear chemistry and related courses should be introduced into undergraduate chemistry curricula at universities worldwide. Starting from these statements, an ideal program in an undergraduate chemistry curriculum was proposed to be introduced into the undergraduate chemistry program at the Department of Chemistry, Ege University, in Izmir, Turkey during the regular updating of the chemistry curriculum. Thus, it has been believed that this Department of Chemistry has recently gained an ideal teaching program in the field of nuclear chemistry and its applications in scientific, industrial, and medical sectors. In this contribution, the details of this program will be discussed. (author)

Future perspectives of radiation chemistry are discussed by the analysis of the related information in detail as obtained from our recent surveys of publications and scientific meetings in radiation chemistry and its neighboring research fields, giving some examples, and are summarized as follows. (1) Traditionally important core-parts of radiation chemistry should be activated more. The corresponding research programs are listed in detail. (2) Research fields of physics, chemistry, biology, medicine, and technology in radiation research should interact more among them with each other. (3) Basic research of radiation chemistry should interact more with its applied research. (4) Interface research fields with radiation chemistry should be produced more with mutually common viewpoints and research interests between the two. Interfaces are not only applied research but also basic one.

Learner-Directed Nutrition Content for Medical Schools to Meet LCME Standards

Directory of Open Access Journals (Sweden)

Lisa A. Hark

2015-01-01

Full Text Available Deficiencies in medical school nutrition education have been noted since the 1960s. Nutrition-related non-communicable diseases, including heart disease, stroke, cancer, diabetes, and obesity, are now the most common, costly, and preventable health problems in the US. Training medical students to assess diet and nutritional status and advise patients about a healthy diet, exercise, body weight, smoking, and alcohol consumption are critical to reducing chronic disease risk. Barriers to improving medical school nutrition content include lack of faculty preparation, limited curricular time, and the absence of funding. Several new LCME standards provide important impetus for incorporating nutrition into existing medical school curriculum as self-directed material. Fortunately, with advances in technology, electronic learning platforms, and web-based modules, nutrition can be integrated and assessed across all four years of medical school at minimal costs to medical schools. Medical educators have access to a self-study nutrition textbook, Medical Nutrition and Disease, Nutrition in Medicine© online modules, and the NHLBI Nutrition Curriculum Guide for Training Physicians. This paper outlines how learner-directed nutrition content can be used to meet several US and Canadian LCME accreditation standards. The health of the nation depends upon future physicians’ ability to help their patients make diet and lifestyle changes.

Synthesis meets theory: Past, present and future of rational chemistry

Science.gov (United States)

Fianchini, Mauro

2017-11-01

Chemical synthesis has its roots in the empirical approach of alchemy. Nonetheless, the birth of the scientific method, the technical and technological advances (exploiting revolutionary discoveries in physics) and the improved management and sharing of growing databases greatly contributed to the evolution of chemistry from an esoteric ground into a mature scientific discipline during these last 400 years. Furthermore, thanks to the evolution of computational resources, platforms and media in the last 40 years, theoretical chemistry has added to the puzzle the final missing tile in the process of "rationalizing" chemistry. The use of mathematical models of chemical properties, behaviors and reactivities is nowadays ubiquitous in literature. Theoretical chemistry has been successful in the difficult task of complementing and explaining synthetic results and providing rigorous insights when these are otherwise unattainable by experiment. The first part of this review walks the reader through a concise historical overview on the evolution of the "model" in chemistry. Salient milestones have been highlighted and briefly discussed. The second part focuses more on the general description of recent state-of-the-art computational techniques currently used worldwide by chemists to produce synergistic models between theory and experiment. Each section is complemented by key-examples taken from the literature that illustrate the application of the technique discussed therein.

Full Text Available Background and objectives : Meetings are inseparable part of organizational world which cost high. The aim of this study was to analyze the effectiveness of the meetings held in Tabriz University of Medical Sciences from personnel’s perspective in management setting. Material and Methods : This is a cross-sectional, descriptive study. The study community consisted of 207 managers in different directorship positions in which 82 of them were selected as the sample by using Kookran formula. Data were collected using researcher-made which its validity and reliability were achieved according to Likert spectrum. Data were analyzed by SPSS software version 16. The applied tests included independent T test and Anova. Results : Personnel dedicated 75% of total score for pre meeting processes and meeting management and 32% for the effectiveness of the meetings in the process of achieving the goals, satisfaction from holding the meetings and effective participation in the meetings. In other words, they were compliant with the quality of the meetings but disagreed on the effectiveness of the meetings. Also, these findings showed meaningful relationship between effectiveness and quality of the meetings with age and educational courses. However, there was no meaningful difference between effectiveness and quality of the meetings with gender, level of education and field of study (p>0.05. Conclusion : In order to improve the quality and effectiveness of the meetings, it is necessary to hold meetings’ invitation, beginning and finishing on-time. In addition, participants should be focused and informed about the subjects of the meeting. Furthermore, empowering managers and personnel in different management positions by holding educational packages and workshops is suggested.

Flow chemistry and continuous processing techniques are beginning to have a profound impact on the production of functional materials ranging from quantum dots, nanoparticles and metal organic frameworks to polymers and dyes. These techniques provide robust procedures which not only enable accurate control of the product material's properties but they are also ideally suited to conducting experiments on scale. The modular nature of flow and continuous processing equipment rapidly facilitates reaction optimisation and variation in function of the products. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Motivation in medical education and patient communication. The EGPRN meeting in Zurich, Switzerland, October 2010.

Science.gov (United States)

Rethans, Jan-Joost; Donner-Banzhoff, Norbert

2011-06-01

The European General Practice Research Network held an international research meeting on 'Motivation in medical education and patient communication' in Zürich, Switzerland, in October 2010. The two authors were keynote speakers, who introduced the theme from different angles and summarized and reflected on individual papers presented at the conference. The theme of the conference underlined the importance of communication in general practice and of motivation in medical education in particular. There were a variety of papers each addressing in its own way the topic of this meeting. We conclude that it is still uncommon to use psychological theories on motivation in research on motivation and patient communication in general practice/family medicine. Motivation and readiness to change are essential concepts in experimental health services research. Research designs increasingly follow the Framework for the Evaluation of Complex Interventions in Health Care as suggested by the British Medical Research Council. However, there are also difficulties related to classical experimental designs that have to be critically discussed.

Simulation-based medical education can provide medical training in a nonjudgmental, patient-safe, and effective environment. Although simulation has been a relatively new addition to medical education, the aeronautical, judicial, and military fields have used simulation training for hundreds of years, with positive outcomes. Simulation-based medical education can be used in a variety of settings, such as hospitals, outpatient clinics, medical schools, and simulation training centers. As the author describes in the present article, residencies currently accredited by the American Osteopathic Association can use a simulation-based medical education curriculum to meet training requirements of the 6 competencies identified by the Accreditation Council for Graduate Medical Education. The author also provides specific guidance on providing training and assessment in the professionalism competency.

Hussain, M.

2011-01-01

Chemistry is one of the oldest branches of science; the human beings had ever come across. It has consistently contributed towards meeting the human needs from the dawn of civilization. However, its role has multiplied since the inception of industrial revolution. Although anthropogenic activities have made the human life comfortable and even luxurious yet their impacts on the physical, biological and socio-economic environments had been destructive. Numerous kinds of chemicals have engulfed us and our environment. Modern chemistry has leading role in sculpting the present as well as future of human lifestyle. It is serving the man and other biodiversity by providing countless products in every sphere of life. At the same time it is playing villain role in the destruction of environment at an alarming rate. Today the world is confronted with heinous environmental issues hitherto unknown to the living beings mostly triggered by chemicals. Thousands of chemicals are used in industrial products, agricultural chemicals, persistent organic pollutants, freezers, pharmaceuticals, chemical and radiological warfare, construction industry, synthetic materials, electrical goods, medical gadgets etc. Some natural sources of chemicals are acid rains, volcanic eruptions, eutrophication and photochemical smog. The fact of matter is that chemicals are being consistently added into atmosphere, biosphere and lithosphere. For the sustainable environment it is imperative that the chemicals must not be added into human environment beyond its carrying capacity. It is responsibility of chemists to introduce environmentally benign and biodegradable chemicals. All types of chemistry need to be green and environment friendly. The scientists and engineers should develop chemicals and technologies which do not harm the living creatures during any stage of their life-cycle. (author)

Medical Deontology towards medical students, our colleagues and our patients. About meetings, medical journals, candidacy for higher posts and the "silent" society.

Science.gov (United States)

Grammaticos, Philip C

2014-01-01

Unfortunately, today very few care about medical deontology-ethics that is about how to behave and respect others when we exercise our medical duties. Perhaps we do not show our real care and kind leadership to our students. We do not very much respect our medical colleagues. We are often tired to spend much time examining patients. We attend medical meetings for pleasure or because our expenses are covered by pharmaceutical firms. We write unimportant papers in order to have a rich curriculum. We consider the Impact Factor of a journal as awarded only to underline the importance of a letter to the Editor we publish in a prestigious journal. We refrain from useful research. We are not always truthful in publishing the results of our research. Many such examples are included in this paper. Overall, we go for a financial success disregarding the "old" Hippocratic ideas and oath. We are supposed to seak for life-happiness. Instead, we feel guilty, inconvenient as to our social behaviour and unhappy. "The Lancet" mentioned long ago (1969) a phrase by John Keats: "Truth is beauty...this only exists on Earth and this is what we need to know".

Optimum coolant chemistry in BWRs

International Nuclear Information System (INIS)

Lin, C.C.; Cowan, R.L.; Kiss, E.

2004-01-01

LWR water chemistry parameters are directly or indirectly related to the plant's operational performance and for a significant amount of Operation and Maintenance (O and M) costs. Obvious impacts are the operational costs associated with water treatment, monitoring and associated radwaste generation. Less obvious is the important role water chemistry plays in the magnitude of drywell shutdown dose rates, fuel corrosion performance and, (probably most importantly) materials degradation such as from stress corrosion cracking of piping and Reactor Pressure Vessel (RPV) internal components. To improve the operational excellence of the BWR and to minimize the impact of water chemistry on O and M costs. General Electric has developed the concept of Optimum Water Chemistry (OWC). The 'best practices' and latest technology findings from the U.S., Asia and Europe are integrated into the suggested OWC Specification. This concept, together with cost effective ways to meet the requirement, are discussed. (author)

Water chemistry control to meet the advanced design and operation of light water reactors

Shirai, Hiroshi; Uchida, Shunsuke; Naitoh, Masanori; Okada, Hidetoshi; Sato, Masatoshi

2014-01-01

Water chemistry control is one of the key technologies to establish safe and reliable operation of nuclear power plants. The road maps on R and D plans for water chemistry of nuclear power systems in Japan have been proposed along with promotion of R and D related water chemistry improvement for the advanced application of light water reactors (LWRs). The technical trends were divided into four categories, dose rate reduction, structural integrity, fuel integrity and radioactive waste reduction, and latest technical break through for each category was shown for the advanced application of LWRs. At the same time, the technical break through and the latest movements for regulation of water chemistry were introduced for each of major organizations related to nuclear engineering in the world. The conclusions were summarized as follows; 1. Water chemistry improvements might contribute to achieve the advanced application of LWRs, while water chemistry should be often changed to achieve the advanced application of LWRs. 2. Only one solution for water chemistry control was not obtained for achieving the advanced application of LWRs, but miscellaneous solutions were possible for achieving one. Optimal water chemistry control was desired for having the good practices for satisfying multi-targets at the same time and it was much affected by the plant unique systems and operational history. 3. That meant it was difficult to determine water chemistry regulation targets for achieving application of LWRs but it was necessary to prepare suitable guideline for good achievement of application of LWRs. That meant the guideline should be recommendation for good practice in the plant. 4. The water chemistry guide line should be modified along with progress of plant operation and water chemistry and related technologies. (author)

EDITORIAL: Nano Meets Spectroscopy Nano Meets Spectroscopy

Birch, David J. S.

2012-08-01

The multidisciplinary two-day Nano Meets Spectroscopy (NMS) event was held at the National Physical Laboratory (NPL), Teddington, UK, in September 2011. The event was planned from the outset to be at the interface of several areas—in particular, spectroscopy and nanoscience, and to bring together topics and people with different approaches to achieving common goals in biomolecular science. Hence the meeting cut across traditional boundaries and brought together researchers using diverse techniques, particularly fluorescence and Raman spectroscopy. Despite engaging common problems, these techniques are frequently seen as mutually exclusive with the two communities rarely interacting at conferences. The meeting was widely seen to have lived up to its billing in good measure. It attracted the maximum capacity of ~120 participants, including 22 distinguished speakers (9 from outside the UK), over 50 posters and a vibrant corporate exhibition comprising 10 leading instrument companies and IOP Publishing. The organizers were Professor David Birch (Chair), Dr Karen Faulds and Professor Duncan Graham of the University of Strathclyde, Professor Cait MacPhee of the University of Edinburgh and Dr Alex Knight of NPL. The event was sponsored by the European Science Foundation, the Institute of Physics, the Royal Society of Chemistry, NPL and the Scottish Universities Physics Alliance. The full programme and abstracts are available at http://sensor.phys.strath.ac.uk/nms/program.php. The programme was quite ambitious in terms of the breadth and depth of scope. The interdisciplinary and synergistic concept of 'X meets Y' played well, cross-fertilization between different fields often being a source of inspiration and progress. Fluorescence and Raman spectroscopy provided the core, but the meeting had little repetition and also attracted contributions on more specialist techniques such as CARS, super-resolution, single molecule and chiral methods.

Autoverification in a core clinical chemistry laboratory at an academic medical center

Directory of Open Access Journals (Sweden)

Matthew D Krasowski

2014-01-01

Full Text Available Background: Autoverification is a process of using computer-based rules to verify clinical laboratory test results without manual intervention. To date, there is little published data on the use of autoverification over the course of years in a clinical laboratory. We describe the evolution and application of autoverification in an academic medical center clinical chemistry core laboratory. Subjects and Methods: At the institution of the study, autoverification developed from rudimentary rules in the laboratory information system (LIS to extensive and sophisticated rules mostly in middleware software. Rules incorporated decisions based on instrument error flags, interference indices, analytical measurement ranges (AMRs, delta checks, dilution protocols, results suggestive of compromised or contaminated specimens, and ′absurd′ (physiologically improbable values. Results: The autoverification rate for tests performed in the core clinical chemistry laboratory has increased over the course of 13 years from 40% to the current overall rate of 99.5%. A high percentage of critical values now autoverify. The highest rates of autoverification occurred with the most frequently ordered tests such as the basic metabolic panel (sodium, potassium, chloride, carbon dioxide, creatinine, blood urea nitrogen, calcium, glucose; 99.6%, albumin (99.8%, and alanine aminotransferase (99.7%. The lowest rates of autoverification occurred with some therapeutic drug levels (gentamicin, lithium, and methotrexate and with serum free light chains (kappa/lambda, mostly due to need for offline dilution and manual filing of results. Rules also caught very rare occurrences such as plasma albumin exceeding total protein (usually indicative of an error such as short sample or bubble that evaded detection and marked discrepancy between total bilirubin and the spectrophotometric icteric index (usually due to interference of the bilirubin assay by immunoglobulin (Ig M monoclonal

Medical education... meet Michel Foucault.

Science.gov (United States)

Hodges, Brian D; Martimianakis, Maria A; McNaughton, Nancy; Whitehead, Cynthia

2014-06-01

There have been repeated calls for the greater use of conceptual frameworks and of theory in medical education. Although it is familiar to few medical educators, Michel Foucault's work is a helpful theoretical and methodological source. This article explores what it means to use a 'Foucauldian approach', presents a sample of Foucault's historical-genealogical studies that are relevant to medical education, and introduces the work of four researchers currently undertaking Foucauldian-inspired medical education research. Although they are not without controversy, Foucauldian approaches are employed by an increasing number of scholars and are helpful in shedding light on what it is possible to think, say and be in medical education. Our hope in sharing this Foucauldian work and perspective is that we might stimulate a dialogue that is forward-looking and optimistic about the possibilities for change in medical education. © 2014 John Wiley & Sons Ltd.

SU-A-210-00: AAPM Medical Physics Student Meeting: Medical Billing and Regulations: Everything You Always Wanted To Know, But Were Too Afraid To Ask

Energy Technology Data Exchange (ETDEWEB)

NONE

2015-06-15

The purpose of this student annual meeting is to address topics that are becoming more relevant to medical physicists, but are not frequently addressed, especially for students and trainees just entering the field. The talk is divided into two parts: medical billing and regulations. Hsinshun Wu – Why should we learn radiation oncology billing? Many medical physicists do not like to be involved with medical billing or coding during their career. They believe billing is not their responsibility and sometimes they even refuse to participate in the billing process if given the chance. This presentation will talk about a physicist’s long career and share his own experience that knowing medical billing is not only important and necessary for every young medical physicist, but that good billing knowledge could provide a valuable contribution to his/her medical physics development. Learning Objectives: The audience will learn the basic definition of Current Procedural Terminology (CPT) codes performed in a Radiation Oncology Department. Understand the differences between hospital coding and physician-based or freestanding coding. Apply proper CPT coding for each Radiation Oncology procedure.

SU-A-210-00: AAPM Medical Physics Student Meeting: Medical Billing and Regulations: Everything You Always Wanted To Know, But Were Too Afraid To Ask

International Nuclear Information System (INIS)

2015-01-01

The purpose of this student annual meeting is to address topics that are becoming more relevant to medical physicists, but are not frequently addressed, especially for students and trainees just entering the field. The talk is divided into two parts: medical billing and regulations. Hsinshun Wu – Why should we learn radiation oncology billing? Many medical physicists do not like to be involved with medical billing or coding during their career. They believe billing is not their responsibility and sometimes they even refuse to participate in the billing process if given the chance. This presentation will talk about a physicist’s long career and share his own experience that knowing medical billing is not only important and necessary for every young medical physicist, but that good billing knowledge could provide a valuable contribution to his/her medical physics development. Learning Objectives: The audience will learn the basic definition of Current Procedural Terminology (CPT) codes performed in a Radiation Oncology Department. Understand the differences between hospital coding and physician-based or freestanding coding. Apply proper CPT coding for each Radiation Oncology procedure. Each procedure with its specific CPT code will be discussed in detail. The talk will focus on the process of care and use of actual workflow to understand each CPT code. Example coding of a typical Radiation Oncology procedure. Special procedure coding such as brachytherapy, proton therapy, radiosurgery, and SBRT.

Interpersonal chemistry refers to a connection between two individuals that exists upon first meeting. The goal of the current study is to identify beliefs about the underlying components of friendship chemistry. Individuals respond to an online Friendship Chemistry Questionnaire containing items that are derived from interdependence theory and the friendship formation literature. Participants are randomly divided into two subsamples. A principal axis factor analysis with promax rotation is performed on subsample 1 and produces 5 factors: Reciprocal candor, mutual interest, personableness, similarity, and physical attraction. A confirmatory factor analysis is conducted using subsample 2 and provides support for the 5-factor model. Participants with agreeable, open, and conscientious personalities more commonly report experiencing friendship chemistry, as do those who are female, young, and European/white. Responses from participants who have never experienced chemistry are qualitatively analyzed. Limitations and directions for future research are discussed.

The growing demand for a competent health workforce to meet the needs of increasingly diverse societies has been widely acknowledged. One medical school in New Zealand explored the integration of the commonly used patient-centred model approach, with an intersectional framework in the development of a cultural competency training programme. In the Pacific Immersion Programme, medical students in their fourth year of training are given the opportunity to learn about different factors that influence the health and health care of a minority community through immersion in that community. The programme objectives include enabling students to learn through experience living within the local community context, and supporting them to re-evaluate their own personal beliefs, assumptions and/or prior prejudices. This study evaluates the usefulness of this programme in the training of medical students to work in diverse communities. Two analytical approaches were used for evaluation. Deductive and inductive analyses were conducted on 235 reflective essays completed by three cohorts of students from 2011 to 2013 to ascertain the value of the programme for student learning. In addition, one cohort was invited to complete a pre and post-programme questionnaire. Overall, the students found the programme to be a valued learning environment. They found living within a Pacific family environment to be an eye opening experience. It increased students comfort level in cross cultural engagement and emphasised the importance of patient's perspectives in health care provision. Students' self-reported knowledge about Pacific cultural values, protocols, traditional beliefs and the main health challenges increased significantly after the programme. They appreciated learning directly from community members, and through observations about how culture, beliefs and the socio-economic environment influence peoples' health and wellbeing. Medical schools are required to train a competent health

A summary is given of the first IAEA research coordination meeting on ''Nuclear Data for Charged-particle Monitor Reactions and Medical Isotope Production'. Participants reassessed and reviewed the requirements for both cross-section and decay data, based on the earlier findings of three IAEA consultants' meetings (High-precision beta-intensity measurements and evaluations for specific PET radioisotopes, INDC(NDS)-0535, December 2008; Improvements in charged-particle monitor reactions and nuclear data for medical isotope production, INDC(NDS)-0591, September 2011; Intermediate-term nuclear data needs for medical applications: cross sections and decay data, INDC(NDS)-0596, September 2011). While significant emphasis was placed on the needs defined in IAEA report INDC(NDS)-0591, a limited number of relevant items and issues were also considered from the other two technical meetings. Recommendations focused on cross-section studies for a reasonably wide range of targets and projectiles, along with decay data measurements and evaluations for specific radionuclides. Individual presentations and discussions are described in this report, along with listings of the agreed work packages to be undertaken by the participants of the coordinated research project.

Medical deontology, meetings, journals, candidacy for higher posts and how to better enjoy life.

Unfortunately, today few physicians care about medical deontology and medical ethics, that is how to behave and respect others when exercising our medical profession. Some of us may not show the care and kindness we should show towards our students or the due respect to our senior colleagues. Occasionally, when examining our patients we may not pay the proper attention to their problems, being tired from work overload. Another issue of deontology is medical meetings. Do they offer us enough knowledge or mainly pleasure? Is our curriculum vitae comprised by useful to society and to medicine original or confirmatory research work? Few examples to illustrate what the situation is at present are included in this paper. Our financial success in practice should not compete with the "old" Hippocratic oath and ideals. The pursuit of happiness in our life is not achieved through untruthfulness, dishonesty or only high financial status.

Research needs and opportunities in radiation chemistry workshop

Energy Technology Data Exchange (ETDEWEB)

Barbara, Paul F

1998-04-19

There is a growing urgency for forefront basic research on ionizing radiation-induced chemical reactions, due to the relevance of these reactions in such areas of critical national need as environmental waste management, environmental remediation, nuclear energy production, and medical diagnosis and radiation therapy. Fortunately, the emergence of new theoretical and experimental tools for the study of radiation-induced chemical and physical processes, i.e. Radiation Chemistry, makes future progress quite promising. Nevertheless, a recent decline in he number of young investigators in radiation chemistry, as well as a natural obsolescence of large research facilities in radiation chemistry are serious obstacles to further progress. Understanding radiation-induced processes is of vital significance in such diverse fields as waste remediation in environmental cleanup, radiation processing of polymers and food, medical diagnosis and therapy, catalysis of chemical reactions, environmentally benign synthesis, and nuclear energy production. Radiation chemistry provides for these fields fundamental quantitative data, such as reaction rate coefficients, diffusion coefficients, radiation chemical yields, etc. As well as providing useful quantitative information of technological and medical importance, radiation chemistry is also a valuable tool for solving fundamental problems in chemistry and in material sciences. Exploiting the many facets of radiation chemistry requires a thorough and comprehensive understanding of the underlying chemical and physical processes. An understanding of the structure and dynamics of “tracks” produced by ionizing radiation is a central issue in the field. There is a continuing need to study the ultrafast processes that link the chemistry and physics of radiation-induced phenomena. This is especially true for practically important, but less well understood, nonstandard environments such as interfacial systems, supercritical media, and

Babcock and Wilcox (B and W) has developed a computerized water chemistry data acquisition and management system for nuclear plant secondary coolant systems. The Integrated Water Chemistry Monitoring System (IWCMS) provides on-line monitoring of conditions and rapid trend analysis of sampled data. So far it has been installed at GPU Three Mile Island unit 1 and at Toledo Edison Davis-Besse. The IWCMS meets the following utility needs for monitoring power plant chemistry: control of chemistry conditions to minimize corrosion and extend component/system life; continuous analysis of data from on-line detectors and grab samples; expediting of transient recovery actions with trend, alarm and evaluation capability; provision for rapid sharing of useful operational chemistry information; concentration of attention on evaluation instead of data manipulation. The system is composed of three functional parts: data acquisition hardware; PC-based computer system and customised system software. (author)

Medical Physics Residency Consortium: collaborative endeavors to meet the ABR 2014 certification requirements

In 2009, Mary Bird Perkins Cancer Center (MBPCC) established a Radiation Oncology Physics Residency Program to provide opportunities for medical physics residency training to MS and PhD graduates of the CAMPEP‐accredited Louisiana State University (LSU)‐MBPCC Medical Physics Graduate Program. The LSU‐MBPCC Program graduates approximately six students yearly, which equates to a need for up to twelve residency positions in a two‐year program. To address this need for residency positions, MBPCC has expanded its Program by developing a Consortium consisting of partnerships with medical physics groups located at other nearby clinical institutions. The consortium model offers the residents exposure to a broader range of procedures, technology, and faculty than available at the individual institutions. The Consortium institutions have shown a great deal of support from their medical physics groups and administrations in developing these partnerships. Details of these partnerships are specified within affiliation agreements between MBPCC and each participating institution. All partner sites began resident training in 2011. The Consortium is a network of for‐profit, nonprofit, academic, community, and private entities. We feel that these types of collaborative endeavors will be required nationally to reach the number of residency positions needed to meet the 2014 ABR certification requirements and to maintain graduate medical physics training programs.

Peter Agre, born in 1949 in Northfield Minnesota, shared the 2003 Nobel Prize in Chemistry with Roderick MacKinnon for his discovery of aquaporins, the channel proteins that allow water to cross the cell membrane. Agre's interest medicine was inspired by the humanitarian efforts of the Medical Missionary program run by the Norwegians of his home community in Minnesota. Hoping to provide new treatments for diseases affecting the poor, he joined a cholera laboratory during medical school at Johns Hopkins. He found that he enjoyed biomedical research, and continued his laboratory studies for an additional year after medical school. Agre completed his clinical training at Case Western Hospitals of Cleveland and the University of North Carolina, and returned to Johns Hopkins in 1981. There, his serendipitous discovery of aquaporins was made while pursuing the identity of the Rhesus (Rh) antigen. For a century, physiologists and biophysicists had been trying to understand the mechanism by which fluid passed across the cell's plasma membrane. Biophysical evidence indicated a limit to passive diffusion of water, suggesting the existence of another mechanism for water transport across the membrane. The putative "water channel," however, could not be identified. In 1988, while attempting to purify the 30 kDa Rh protein, Agre and colleagues began investigating a 28 kDa contaminant that they believed to be a proteolytic fragment of the Rh protein. Subsequent studies over the next 3-4 years revealed that the contaminant was a membrane-spanning oligomeric protein, unrelated to the Rh antigen, and that it was highly abundant in renal tubules and red blood cells. Still, they could not assign a function to it. The breakthrough came following a visit with his friend and former mentor John Parker. After Agre described the properties of the mysterious 28 kDa protein, Parker suggested that it might be the long-sought-after water channel. Agre and colleagues tested this idea by

The All-Union Conference on Theoretical and Applied Radiation Chemistry was held in Obninsk in October 1984. The subjects covered by the all-union conference included practically all urgent problems of modern radiation chemistry: theoretical principles of radiation chemistry, solid state radiation chemistry, radiation chemistry of heterogeneous processes, radiolysis of organic and inorganic substances, radiation polymerization and hardening, radiation chemistry of polymers, the technology of radiation chemistry and instrument making. Twenty-three plenary reports given by scientists representing the corresponding directions were devoted to an examination of the basic problems of modern radiation chemistry. Around 100 oral communications were heard and discussed at meetings of six sections operating within the framework of the conference. In addition the conference participants were able to acquaint themselves with and discuss more than 230 displays in parallel with the oral reports. Abstracts of all of the section oral reports and displays were published by the organizing committee in the form of a separate collection. The texts of the plenary reports were published in the journal Khimiya Vysokikh Energiy in 1985.

To meet regulatory needs for sodium fast reactors’ future development, including licensing requirements, Sandia National Laboratories is modernizing MELCOR, a severe accident analysis computer code developed for the U.S. Nuclear Regulatory Commission (NRC). Specifically, Sandia is modernizing MELCOR to include the capability to model sodium reactors. However, Sandia’s modernization effort primarily focuses on the containment response aspects of the sodium reactor accidents. Sandia began modernizing MELCOR in 2013 to allow a sodium coolant, rather than water, for conventional light water reactors. In the past three years, Sandia has been implementing the sodium chemistry containment models in CONTAIN-LMR, a legacy NRC code, into MELCOR. These chemistry models include spray fire, pool fire and atmosphere chemistry models. Only the first two chemistry models have been implemented though it is intended to implement all these models into MELCOR. A new package called “NAC” has been created to manage the sodium chemistry model more efficiently. In 2017 Sandia began validating the implemented models in MELCOR by simulating available experiments. The CONTAIN-LMR sodium models include sodium atmosphere chemistry and sodium-concrete interaction models. This paper presents sodium property models, the implemented models, implementation issues, and a path towards validation against existing experimental data.

Advances in BWR water chemistry

Garcia, Susan E.; Giannelli, Joseph F.; Jarvis, Mary L.

2012-09-01

This paper reviews recent advances in Boiling Water Reactor (BWR) water chemistry control with examples of plant experiences at U.S. designed BWRs. Water chemistry advances provide some of the most effective methods for mitigating materials degradation, reducing fuel performance concerns and lowering radiation fields. Mitigation of stress corrosion cracking (SCC) of materials remains a high priority and improved techniques that have been demonstrated in BWRs will be reviewed, specifically hydrogen injection combined with noble metal chemical addition (NMCA) and the newer on-line noble metal application process (OLNC). Hydrogen injection performance, an important part of SCC mitigation, will also be reviewed for the BWR fleet, highlighting system improvements that have enabled earlier injection of hydrogen including the potential for hydrogen injection during plant startup. Water chemistry has been significantly improved by the application of pre-filtration and optimized use of ion exchange resins in the CP (condensate polishing) and reactor water cleanup (RWCU) systems. EPRI has monitored and supported water treatment improvements to meet water chemistry goals as outlined in the EPRI BWR Water Chemistry Guidelines, particularly those for SCC mitigation of reactor internals and piping, minimization of fuel risk due to corrosion and crud deposits and chemistry control for radiation field reduction. In recent years, a significant reduction has occurred in feedwater corrosion product input, particularly iron. A large percentage of plants are now reporting <0.1 ppb feedwater iron. The impacts to plant operation and chemistry of lower feedwater iron will be explored. Depleted zinc addition is widely practiced across the fleet and the enhanced focus on radiation reduction continues to emphasize the importance of controlling radiation source term. In addition, shutdown chemistry control is necessary to avoid excessive release of activated corrosion products from fuel

Four activities were implemented in a pharmacy skills laboratory (PSL) for second-year pharmacy students. Students (n=121) worked individually on exercises for three of the four activities. Pre/post-laboratory surveys on self-efficacy were administered. The McNemar test was performed to evaluate students' self-efficacy above 70% related to course outcomes before and after the exercises in each activity. An independent t test was conducted to compare the mean of students' responses on meeting course outcomes based on the 70% anchor for the perspective confidence on meeting course outcomes. Results. The post-PSL scores on all self-efficacy questions improved. The majority of students reported skill development in all exercises. Students and clinical faculty qualitative responses indicated they felt exercises were effective. Conclusion. A PSL can serve as a valuable opportunity to address course related educational outcomes and specific skill development and can help students assess their self-efficacy in meeting them.

Medical biochemistry in Macedonia: a profession for physicians and natural scientists.

Science.gov (United States)

Traikovska, S; Dzhekova-Stojkova, S

2001-06-01

Medical biochemistry or clinical chemistry in its roots is an interdisciplinary science between natural sciences and medicine. The largest part of medical biochemistry is natural science (chemistry, biochemistry, biology, physics, mathematics), which is very well integrated in deduction of medical problems. Medical biochemistry throughout the world, including Macedonia, should be a professional field open to both physicians and natural scientists, according to its historical development, theoretical characteristics and applied practice. Physicians and natural scientists follow the same route in clinical chemistry during the postgraduate training of specialization in medical biochemistry/clinical chemistry. However, in Macedonia the specialization in medical biochemistry/clinical chemistry is today regulated by law only for physicians and pharmacists. The study of clinical chemistry in Europe has shown its interdisciplinary character. In most European countries different professions, such as physicians, chemists/biochemists, pharmacists, biologists and others could specialize in clinical chemistry. The question for the next generation of specialists in Macedonia is whether to accept the present conditions or to attempt to change the law to include chemists/biochemists and biologists as well. The latter used to be a practice in Macedonia 20 years ago, and still is in many European countries. Such change in law would also result in changes in the postgraduate educational program in medical biochemistry in Macedonia. The new postgraduate program has to follow the European Syllabus, recommended by EC4. To obtain sufficient knowledge in clinical chemistry, the duration of vocational training (undergraduate and postgraduate) for all trainees (physicians, pharmaceutics, chemists/biochemists and biologists) should be 8 years.

On being green: can flow chemistry help?

The principles of Green Chemistry are important but challenging drivers for most modern synthesis programs. To meet these challenges new flow chemistry tools are proving to be very effective by providing improved heat/mass transfer opportunities, lower solvent usage, less waste generation, hazardous compound containment, and the possibility of a 24/7 working regime. This machine-assisted approach can be used to effect repetitive or routine scale-up steps or when combined with reagent and scavenger cartridges, to achieve multi-step synthesis of complex natural products and pharmaceutical agents.

2011-01-01

The need for a revised curriculum within the life sciences has been well-established. One strategy to improve student preparation in the life sciences is to redesign introductory courses like biology, chemistry, and physics so that they better reflect their disciplinary interdependence. We describe a medically relevant, context-based approach to teaching second semester general chemistry that demonstrates the interdisciplinary nature of biology and chemistry. Our innovative method provides a model in which disciplinary barriers are diminished early in the undergraduate science curriculum. The course is divided into three principle educational modules: 1) Fundamentals of General Chemistry, 2) Medical Approaches to Inflammation, and 3) Neuroscience as a connector of chemistry, biology, and psychology. We accurately anticipated that this modified approach to teaching general chemistry would enhance student interest in chemistry and bridge the perceived gaps between biology and chemistry. The course serves as a template for context-based, interdisciplinary teaching that lays the foundation needed to train 21st century scientists. Copyright © 2010 Wiley Periodicals, Inc.

Nonlinear Oscillations in Biology and Chemistry

CERN Document Server

1986-01-01

This volume contains the proceedings of a meeting entitled 'Nonlinear Oscillations in Biology and Chemistry', which was held at the University of Utah May 9-11,1985. The papers fall into four major categories: (i) those that deal with biological problems, particularly problems arising in cell biology, (ii) those that deal with chemical systems, (iii) those that treat problems which arise in neurophysiology, and (iv), those whose primary emphasis is on more general models and the mathematical techniques involved in their analysis. Except for the paper by Auchmuty, all are based on talks given at the meeting. The diversity of papers gives some indication of the scope of the meeting, but the printed word conveys neither the degree of interaction between the participants nor the intellectual sparks generated by that interaction. The meeting was made possible by the financial support of the Department of Mathe­ matics of the University of Utah. I am indebted to Ms. Toni Bunker of the Department of Mathematics for...

In order to establish a systematic and synthetic knowledge system of nuclear water chemistry, we held nuclear water chemistry experts group meetings. We discussed the way of buildup and propagation of nuclear water chemistry knowledge with domestic experts. We obtained a lot of various opinions that made the good use of this research project. The results will be applied to continuous buildup of domestic nuclear water chemistry knowledge database. Lessons in water chemistry of nuclear power plants (NPPs) have been opened in Nuclear Training and education Center, KAERI to educate the new generation who are working and will be working at the department of water chemistry of NPPs. The lessons were 17 and lesson period was from 12th May through 5th November. In order to progress the programs, many water chemistry experts were invited. They gave lectures to the younger generation once a week for 2 h about their experiences obtained during working on water chemistry of NPPs. The number of attendance was 290. The lessons were very effective and the lesson data will be used to make database for continuous use

2018-03-01

Gluten-related disorders are a complex group of diseases that involve the activation of the immune system triggered by the ingestion of gluten. Among these, celiac disease, with a prevalence of 1 %, is the most investigated, but recently, a new pathology, named nonceliac gluten sensitivity, was reported with a general prevalence of 7 %. Finally, there other less-prevalent gluten-related diseases such as wheat allergy, gluten ataxia, and dermatitis herpetiformis (with an overall prevalence of less than 0.1 %). As mentioned, the common molecular trigger is gluten, a complex mixture of storage proteins present in wheat, barley, and a variety of oats that are not fully degraded by humans. The most-studied protein related to disease is gliadin, present in wheat, which possesses in its sequence many pathological fragments. Despite a lot of effort to treat these disorders, the only effective method is a long-life gluten-free diet. This Review summarizes the actual knowledge of gluten-related disorders from a translational chemistry point of view. We discuss what is currently known from the literature about the interaction of gluten with the gut and the critical host responses it evokes and, finally, connect them to our current and novel molecular understanding of the supramolecular organization of gliadin and the 33-mer gliadin peptide fragment under physiological conditions.

Many nations are struggling with the design, implementation, and ongoing improvement of health care systems to meet the needs of their citizens. In the United Arab Emirates, a small nation with vast wealth, the lives of average citizens have evolved from a harsh, nomadic existence to enjoyment of the comforts of modern life. Substantial progress has been made in the provision of education, housing, health, employment, and other forms of social advancement. Having covered these basic needs, the government of Abu Dhabi, United Arab Emirates, is responding to the challenge of developing a comprehensive health system to serve the needs of its citizens, including restructuring the nation's graduate medical education (GME) system. We describe how Abu Dhabi is establishing GME policies and infrastructure to develop and support a comprehensive health care system, while also being responsive to population health needs. We review recent progress in developing a systematic approach for developing GME infrastructure in this small emirate, and discuss how the process of designing a GME system to meet the needs of Emirati citizens has benefited from the experience of "Western" nations. We also examine the challenges we encountered in this process and the solutions adopted, adapted, or specifically developed to meet local needs. We conclude by highlighting how our experience "at the GME drawing board" reflects the challenges encountered by scholars, administrators, and policymakers in nations around the world as they seek to coordinate health care and GME resources to ensure care for populations.

Participants included medical publication professionals from industry, communication agencies, and journals. DISCUSSION TOPICS: Roundtable participants discussed how to best interpret and implement various guidances, such as Good Publication Practices 2 (GPP2), the International Committee of Medical Journal Editors (ICMJE) guidelines, and the Physician Payment Sunshine Act. The impact of and compliance with Corporate Integrity agreements (CIAs) on medical publication planning practices was debated. Roundtable participants also discussed ways of advancing both advocacy for the medical publication professional field and internal and external collaborations. The development of review manuscripts, publications from regions newly emerging in publication planning, medical devices publications, and real-world experience publications were discussed. Participants also considered the benefits and uncertainties of new technologies in medical publications such as multimedia and social media. This is the first ever article to be published following the well-attended ISMPP roundtable sessions. The objective of this manuscript is to summarize key learnings that will aid continued discussions about challenges and opportunities facing medical publication professionals.

Big Data Meets Quantum Chemistry Approximations: The Δ-Machine Learning Approach.

Ramakrishnan, Raghunathan; Dral, Pavlo O; Rupp, Matthias; von Lilienfeld, O Anatole

2015-05-12

Chemically accurate and comprehensive studies of the virtual space of all possible molecules are severely limited by the computational cost of quantum chemistry. We introduce a composite strategy that adds machine learning corrections to computationally inexpensive approximate legacy quantum methods. After training, highly accurate predictions of enthalpies, free energies, entropies, and electron correlation energies are possible, for significantly larger molecular sets than used for training. For thermochemical properties of up to 16k isomers of C7H10O2 we present numerical evidence that chemical accuracy can be reached. We also predict electron correlation energy in post Hartree-Fock methods, at the computational cost of Hartree-Fock, and we establish a qualitative relationship between molecular entropy and electron correlation. The transferability of our approach is demonstrated, using semiempirical quantum chemistry and machine learning models trained on 1 and 10% of 134k organic molecules, to reproduce enthalpies of all remaining molecules at density functional theory level of accuracy.

Medical abortion reversal: science and politics meet.

Medical abortion is a safe, effective, and acceptable option for patients seeking an early nonsurgical abortion. In 2014, medical abortion accounted for nearly one third (31%) of all abortions performed in the United States. State-level attempts to restrict reproductive and sexual health have recently included bills that require physicians to inform women that a medical abortion is reversible. In this commentary, we will review the history, current evidence-based regimen, and regulation of medical abortion. We will then examine current proposed and existing abortion reversal legislation. The objective of this commentary is to ensure physicians are armed with rigorous evidence to inform patients, communities, and policy makers about the safety of medical abortion. Furthermore, given the current paucity of evidence for medical abortion reversal, physicians and policy makers can dispel bad science and misinformation and advocate against medical abortion reversal legislation.

Meeting Disorders.

Yager, Joel; Katzman, Jeffrey W

Although meetings are central to organizational work, considerable time devoted to meetings in Academic Health Centers appears to be unproductively spent. The primary purposes of this article are to delineate and describe Meeting Disorders, pathological processes resulting in these inefficient and ineffective scenarios, and Meeting Fatigue Disorder (MFD), a clinical syndrome. The paper also offers preliminary approaches to remedies. The authors integrate observations made during tens of thousands of hours in administrative meetings in academic medical settings with information in the literature regarding the nature, causes and potential interventions for dysfunctional groups and meetings. Meeting Disorders, resulting from distinct pathologies of leadership and organization, constitute prevalent subgroups of the bureaucrapathologies, pathological conditions caused by dysfunctional bureaucratic processes that generate excesses of wasted time, effort, and other resources. These disorders also generate frustration and demoralization among participants, contributing to professional burnout. Meeting Fatigue Disorder (MFD) is a subjective condition that develops in individuals who overdose on these experiences and may reflect one manifestation of burnout. Meeting disorders and Meeting Fatigue Disorder occur commonly in bureaucratic life. Resources and potential remedies are available to help ameliorate their more deleterious effects.

Evidence-based medicine often has many barriers to overcome prior to implementation in practice, hence the importance of continuous quality improvement. We report on a brief (≤10 minutes) multidisciplinary meeting prior to rounds to establish a dashboard for continuous quality improvement and studied the success of this meeting on a particular area of focus: continuous infusion benzodiazepine minimization. This was a prospective observational study of patients admitted to the medical intensive care unit (MICU) of a large academic medical center over a 4-month period. A morning multidisciplinary prerounding meeting was implemented to report on metrics required to establish a dashboard for MICU care for the previous 24 hours. Fellows and nurse practitioners on respective teams reported on key quality metrics and other important data related to patient census. Continuous benzodiazepines were tracked daily as the number of patients per team who had orders for a continuous benzodiazepine infusion. The aim of this report is to describe the development of the morning multidisciplinary prerounding meeting and its impact on continuous benzodiazepine use, along with associated clinical outcomes. The median number of patients prescribed a continuous benzodiazepine daily decreased over this time period and demonstrated a sustained reduction at 1 year. Furthermore, sedation scores improved, corresponding to a reduction in median duration of mechanical ventilation. The effectiveness of this intervention was mapped post hoc to conceptual models used in implementation science. A brief multidisciplinary meeting to review select data points prior to morning rounds establishes mechanisms for continuous quality improvement and may serve as a mediating factor for successful implementation when initiating and monitoring practice change in the ICU.

The types of information required by hospital and clinical staff can be greatly influenced by the geography and culture of the area in which they operate. In some situations, information must be acquired from sources that fall outside the traditional provisions of a medical or reference library. This article provides examples of the unique information needs of clinical staff serving a primarily Native Alaskan and Native American clientele in Alaska. It also presents sources and personnel utilized to meet those information needs outside of traditional reference sources.

Input of Psychosocial Information During Multidisciplinary Team Meetings at Medical Oncology Departments: Protocol for an Observational Study.

Multidisciplinary team meetings (MDTMs) have become standard practice in oncology and gained the status of the key decision-making forum for cancer patient management. The current literature provides evidence that MDTMs are achieving their intended objectives but there are also indications to question the positive impact of MDTMs in oncology settings. For cancer management to be patient-centered, it is crucial that medical information as well as psychosocial aspects-such as the patients' living situation, possible family problems, patients' mental state, and patients' perceptions and values or preferences towards treatment or care-are considered and discussed during MDTMs. Previous studies demonstrate that failure to account for patients' psychosocial information has a negative impact on the implementation of the treatment recommendations formulated during MDTMs. Few empirical studies have demonstrated the predominant role of physicians during MDTMs, leading to the phenomenon that medical information is shared almost exclusively at the expense of psychosocial information. However, more in-depth insight on the underlying reasons why MDTMs fail to take into account psychosocial information of cancer patients is needed. This paper presents a research protocol for a cross-sectional observational study that will focus on exploring the barriers to considering psychosocial information during MDTMs at medical oncology departments. This protocol encompasses a cross-sectional comparative case study of MDTMs at medical oncology departments in Flanders, Belgium. MDTMs from various oncology subspecialties at inpatient medical oncology departments in multiple hospitals (academic as well as general hospitals) are compared. The observations focus on the "multidisciplinary oncology consultation" (MOC), a formally regulated and financed type of MDTM in Belgian oncology since 2003. Data are collected through nonparticipant observations of MOC-meetings. Observational data are

EPRI BWR Water Chemistry Guidelines Revision

International Nuclear Information System (INIS)

Garcia, Susan E.; Giannelli, Joseph F.

2014-01-01

BWRVIP-190: BWR Water Chemistry Guidelines – 2008 Revision has been revised. The revision committee consisted of U.S. and non-U.S. utilities (members of the BWR Vessel and Internals Protection (BWRVIP) Mitigation Committee), reactor system manufacturers, fuel suppliers, and EPRI and industry experts. The revised document, BWRVIP-190 Revision 1, was completely reformatted into two volumes, with a simplified presentation of water chemistry control, diagnostic and good practice parameters in Volume 1 and the technical bases in Volume 2, to facilitate use. The revision was developed in parallel and in coordination with preparation of the Fuel Reliability Guidelines Revision 1: BWR Fuel Cladding Crud and Corrosion. Guidance is included for plants operating under normal water chemistry (NWC), moderate hydrogen water chemistry (HWC-M), and noble metal application (GE-Hitachi NobleChem™) plus hydrogen injection. Volume 1 includes significant changes to BWR feedwater and reactor water chemistry control parameters to provide increased assurance of intergranular stress corrosion cracking (IGSCC) mitigation of reactor materials and fuel reliability during all plant conditions, including cold shutdown (≤200°F (93°C)), startup/hot standby (>200°F (93°C) and ≤ 10%) and power operation (>10% power). Action Level values for chloride and sulfate have been tightened to minimize environmentally assisted cracking (EAC) of all wetted surfaces, including those not protected by hydrogen injection, with or without noble metals. Chemistry control guidance has been enhanced to minimize shutdown radiation fields by clarifying targets for depleted zinc oxide (DZO) injection while meeting requirements for fuel reliability. Improved tabular presentations of parameter values explicitly indicate levels at which actions are to be taken and required sampling frequencies. Volume 2 provides the technical bases for BWR water chemistry control for control of EAC, flow accelerated corrosion

. Furthermore, improving attitudes and beliefs could be a potential for bringing about successful interventions to general chemistry learning. Importantly, the role of collaboration between chemistry educators is essential to forming instructional strategies. Additionally, shifting paradigms should be given utmost attention, including differences among student engagement in general chemistry, ways in which faculty can modify practices to meet student expectations, and the role of administrators in providing the necessary tools that stimulate chemistry education and research.

Kwang Hye Won(Je Joong Won), the first western hospital in Korea, was founded in 1885. The first western Medical School in Korea was open in 1886 under the hospital management. Dr. O. R. Avison, who came to Korea in 1893, resumed the medical education there, which was interrupted for some time before his arrival in Korea. He inaugurated translating and publishing medical textbooks with the help of Kim Pil Soon who later became one of the first seven graduates in Severance Hospital Medical School. The first western medical textbook translated into Korean was Henry Gray's Anatomy. However, these twice-translated manuscripts were never to be published on account of being lost and burnt down. The existing early anatomy textbooks, the editions of 1906 and 1909, are not the translation of Gray's Anatomy, but that of Japanese anatomy textbook of Gonda. The remaining oldest medical textbook in Korean is Inorganic Materia Medica published in 1905. This book is unique among its kind that O. R. Avison is the only translator of the book and it contains the prefaces of O. R. Avison and Kim Pil Soon. The publication of medical textbook was animated by the participation of other medical students, such as Hong Suk Hoo and Hong Jong Eun. The list of medical textbooks published includes almost all the field of medicine. The medical textbooks in actual existence are as follows: Inorganic Materia Medica (1905), Inorganic Chemistry (1906), Anatomy I (1906), Physiology (1906), Diagnostics I (1906), Diagnostics II (1907), Obstetrics (1908), Organic Chemistry (1909), Anatomy (1909), and Surgery (1910).

Performance feedback is considered essential to clinical skills development. Formative objective structured clinical exams (F-OSCEs) often include immediate feedback by standardized patients. Students can also be provided access to performance metrics including scores, checklists, and video recordings after the F-OSCE to supplement this feedback. How often students choose to review this data and how review impacts future performance has not been documented. We suspect student review of F-OSCE performance data is variable. We hypothesize that students who review this data have better performance on subsequent F-OSCEs compared to those who do not. We also suspect that frequency of data review can be improved with faculty involvement in the form of student-faculty debriefing meetings. Simulation recording software tracks and time stamps student review of performance data. We investigated a cohort of first- and second-year medical students from the 2015-16 academic year. Basic descriptive statistics were used to characterize frequency of data review and a linear mixed-model analysis was used to determine relationships between data review and future F-OSCE performance. Students reviewed scores (64%), checklists (42%), and videos (28%) in decreasing frequency. Frequency of review of all metric and modalities improved when student-faculty debriefing meetings were conducted (p<.001). Among 92 first-year students, checklist review was associated with an improved performance on subsequent F-OSCEs (p = 0.038) by 1.07 percentage points on a scale of 0-100. Among 86 second year students, no review modality was associated with improved performance on subsequent F-OSCEs. Medical students review F-OSCE checklists and video recordings less than 50% of the time when not prompted. Student-faculty debriefing meetings increased student data reviews. First-year student's review of checklists on F-OSCEs was associated with increases in performance on subsequent F-OSCEs, however this

Water chemistry is an important contributor to reliable plant operation, safety barrier integrity, plant component lifetime, radiation safety, environmental impact. Primary and secondary water chemistry guidelines of Russian VVER plants have been modified to meet the new safety standards. At present 14 VVER units of different generation are in operation at 5 Russian NPPs. There are eight 4-loop pressurised water reactors VVER-1000 (1000 MWe) and six 6-loop pressurised water reactors VVER-440 (440 MWe). Generally, water chemistry at East European VVER plants (about 40 VVER-440 and VVER-1000 units in Ukraine, Bulgaria, Slovakia, Czech Republic, Hungary, Finland and Armenia) is similar to water chemistry at Russian VVER plants. Due to similar design and structural materials some water chemistry improvements were introduced at East European plants after they has been successfully implemented at Russian plants and vice versa. Some water chemistry improvements will be implemented at modern VVER plants under construction in Ukraine, Slovakia, Czech Republic, Iran, China, India. (R.P.)

The justification of the practices is the fundamental principle on which rests the peaceful use of ionizing radiations. They actually contain as aspirations to improve the quality of people's lives, contributing to sustainable development through environmental protection, so that the sources security and the individuals protection will be conditions which are not and should can not be operated. For medical applications is a highly illustrative example of this, since both for the diagnosis and therapy, the goal is to achieve what is sought for the white tissue, secured the least possible damage to the neighboring tissues so that in turn reduce the negative effects for the patient. As a basis for achieving the above, it is essential to have qualified personnel in all areas incidents, for example users, workers, officials and staff members. There are a variety of specialists in the field of medical applications as, nuclear chemistry, nuclear engineering, radiation protection, medical physics, radiation physics and others. Among the human resource in the country must make up the majority are medical radiologists, highlighting gaps in the number of radiotherapy and nuclear medicine but specially in the medical physics, who is in some way from a special viewpoint of the formal school, new to the country. This is true for the number of facilities which are in the country. The radiation protection responsibilities in medical applications focus primarily on two figures: the radiology safety manager, who is primarily dedicated to the protection of occupationally exposed personnel and the public, and the medical physicist whose functions are geared towards the radiological protection of the patient. The principal legislation in the medical applications area has been enacted and is monitored by the Health Secretary and National Commission on Nuclear Safety and Safeguards, entities that have reached agreements to avoid overlap and over-regulation.

JOHN LOCKEMEYER

2010-06-25

The Inorganic Chemistry GRC is one of the longest-standing of the GRCs, originating in 1951. Over the years, this conference has played a role in spawning many other GRCs in specialized fields, due to the involvement of elements from most of the periodic table. These include coordination, organometallic, main group, f-element, and solid state chemistries; materials science, catalysis, computational chemistry, nanotechnology, bioinorganic, environmental, and biomedical sciences just to name a few. The 2010 Inorganic Chemistry GRC will continue this tradition, where scientists at all levels from academic, industrial, and national laboratories meet to define the important problems in the field and to highlight emerging opportunities through exchange of ideas and discussion of unpublished results. Invited speakers will present on a wide variety of topics, giving attendees a look at areas both inside and outside of their specialized areas of interest. In addition to invited speakers, the poster sessions at GRCs are a key feature of the conference. All conferees at the Inorganic Chemistry GRC are invited to present a poster on their work, and here the informal setting promotes the free exchange of ideas and fosters new relationships. As in previous years, we will offer poster presenters the opportunity to compete for one of several program spots in which they can give an oral presentation based on the subject matter of their poster. This is a great way to get your work noticed by the scientists attending the meeting, especially for those early in their career path such as junior faculty members, postdoctoral fellows, and those at comparable ranks. Anyone interested in participating in the poster competition should bring an electronic slide presentation and a small hard copy of their poster to submit to the committee.

American Biologist Martin Chalfie shared the 2008 Nobel Prize in Chemistry with Roger Tsien and Osamu Shimomura for their discovery and development of the Green Fluorescent Protein (GFP). Martin Chalfie was born in Chicago in 1947 and grew up in Skokie Illinois. Although he had an interest in science from a young age--learning the names of the planets and reading books about dinosaurs--his journey to a career in biological science was circuitous. In high school, Chalfie enjoyed his AP Chemistry course, but his other science courses did not make much of an impression on him, and he began his undergraduate studies at Harvard uncertain of what he wanted to study. Eventually he did choose to major in Biochemistry, and during the summer between his sophomore and junior years, he joined Klaus Weber's lab and began his first real research project, studying the active site of the enzyme aspartate transcarbamylase. Unfortunately, none of the experiments he performed in Weber's lab worked, and Chalfie came to the conclusion that research was not for him. Following graduation in 1969, he was hired as a teacher Hamden Hall Country Day School in Connecticut where he taught high school chemistry, algebra, and social sciences for 2 years. After his first year of teaching, he decided to give research another try. He took a summer job in Jose Zadunaisky's lab at Yale, studying chloride transport in the frog retina. Chalfie enjoyed this experience a great deal, and having gained confidence in his own scientific abilities, he applied to graduate school at Harvard, where he joined the Physiology department in 1972 and studied norepinephrine synthesis and secretion under Bob Pearlman. His interest in working on C. elegans led him to post doc with Sydney Brenner, at the Medical Research Council Laboratory of Molecular Biology in Cambridge, England. In 1982 he was offered position at Columbia University. When Chalfie first heard about GFP at a research seminar given by Paul Brehm in 1989

Bibliographies on radiation chemistry

Hoffman, M.Z.; Ross, A.B.

The one-electron oxidation and reduction of metal ions and complexes can yield species in unusual oxidation states, and ligand-radicals coordinated to the central metal. These often unstable species can be mechanistically important intermediates in thermal, photochemical, and electrochemical reactions involving metal-containing substances. Their generation via radiolysis provides an alternate means of characterizing them using kinetic and spectroscopic techniques. We hope these bibliographies on the radiation chemistry of metal ions and complexes, presented according to periodic groups, will prove useful to researchers in metallo-redox chemistry. These bibliographies contain only primary literature sources; reviews are not included. However, a list of general review articles on the radiation chemistry of metal ions and complexes is presented here in the first section which covers cobalt, rhodium and iridium, Group 9 in the new IUPAC notation. Additional parts of the bibliography are planned, covering other periodic groups. Part A of the bibliography was prepared by a search of the Radiation Chemistry Data Center Bibliographic Data Base (RCDCbib) through January 1986 for papers on rhodium, iridium and cobalt compounds, and radiolysis (both continuous and pulsed). Papers in which the use of metal compounds was incidental to the primary objective of the study were excluded. Excluded also were publications in unrefereed and obscure sources such as meeting proceedings, internal reports, dissertations, and patents. The majority of the studies in the resultant compilation deal with experiments performed on solutions, mainly aqueous, although a substantial fraction is devoted to solid-state esr measurements. The references are listed in separate sections for each of the metals, and are presented in approximate chronological order. (author)

Pretreatment data is highly predictive of liver chemistry signals in clinical trials.

The goal of this retrospective analysis was to assess how well predictive models could determine which patients would develop liver chemistry signals during clinical trials based on their pretreatment (baseline) information. Based on data from 24 late-stage clinical trials, classification models were developed to predict liver chemistry outcomes using baseline information, which included demographics, medical history, concomitant medications, and baseline laboratory results. Predictive models using baseline data predicted which patients would develop liver signals during the trials with average validation accuracy around 80%. Baseline levels of individual liver chemistry tests were most important for predicting their own elevations during the trials. High bilirubin levels at baseline were not uncommon and were associated with a high risk of developing biochemical Hy's law cases. Baseline γ-glutamyltransferase (GGT) level appeared to have some predictive value, but did not increase predictability beyond using established liver chemistry tests. It is possible to predict which patients are at a higher risk of developing liver chemistry signals using pretreatment (baseline) data. Derived knowledge from such predictions may allow proactive and targeted risk management, and the type of analysis described here could help determine whether new biomarkers offer improved performance over established ones.

Medical biochemistry is the usual name for clinical biochemistry or clinical chemistry in Serbia. Medical biochemistry laboratories and medical biochemists as a profession are part of Health Care System and are regulated through: the Health Care Law and rules issued by the Chamber of Medical Biochemists of Serbia. The first continuous and organized education for Medical Biochemists in Serbia dates from 1945, when Department of Medical Biochemistry was established at Pharmaceutical Faculty in Belgrade. In 1987 at the same Faculty a five years undergraduate branch was established, educating Medical Biochemists under a special program. Since 2006 the new five year undergraduate (according to Bologna Declaration) and postgraduate program of four-year specialization according to EC4 European Syllabus for Post-Graduate Training in Clinical Chemistry and Laboratory Medicine has been established. The Ministry of Education and Ministry of Public Health accredits the programs. There are four requirements for practicing medical biochemistry in the Health Care System: University Diploma of the Faculty of Pharmacy (Medical Biochemistry), successful completion of the profession exam at the Ministry of Health after completion of one additional year of obligatory practical training in medical laboratories, membership in the Serbian Chamber of Medical Biochemists and licence for skilled work issued by Serbian Chamber of Medical Biochemists.

BWR chemistry control status: a summary of industry chemistry status relative to the BWR water chemistry guidelines

Garcia, S.E.; Giannelli, J.F.; Jarvis, M.L.

2010-01-01

The EPRI Boiling Water Reactor (BWR) Water Chemistry Guidelines were revised and issued in October 2008. The 2008 Revision of the Guidelines continues to focus on intergranular stress corrosion cracking (IGSCC), which can limit the service life of susceptible materials and components exposed to water chemistry environments. The 2008 Revision also places increased emphasis on fuel performance and meeting the industry goal of zero fuel failures by 2010. As an industry consensus document, the Guidelines were created to provide proactive water chemistry control strategies for mitigating IGSCC, maintaining fuel integrity and controlling radiation fields. The Guidelines provide a technically-based framework for an effective BWR water chemistry program. This paper provides an overview of industry experience relative to the Guidelines. Over the past few years, many BWR units have implemented noble metal chemical application technologies either during plant hot or cold shutdown or at normal power operating conditions. This paper explores plant experience with optimized water chemistry, implementation of various additive chemistries such as noble metal application and zinc addition, and compliance with the Guidelines recommendations. Depleted zinc oxide addition has been broadly applied across the BWR fleet since the 1980s. The guidance for zinc addition has been revised in the Guidelines to reflect concerns with fuel performance. While zinc addition is a successful method for shutdown dose rate control, concerns still exist for high zinc deposition on fuel surfaces, especially when feedwater iron is elevated and as fuel cores are being driven to provide maximum power output over longer fuel cycles. Recent plant experience has shown that the utilization of online noble metal application and continued zinc addition may provide additional benefits for radiation control.

The development of point-of-care clinical chemistry analyzers has enabled the implementation of these ancillary tests in field laboratories in resource-limited outbreak areas. The Eternal Love Winning Africa (ELWA) outbreak diagnostic laboratory, established in Monrovia, Liberia, to provide Ebola virus and Plasmodium spp. diagnostics during the Ebola epidemic, implemented clinical chemistry analyzers in December 2014. Clinical chemistry testing was performed for 68 patients in triage, including 12 patients infected with Ebola virus and 18 infected with Plasmodium spp. The main distinguishing feature in clinical chemistry of Ebola virus-infected patients was the elevation in alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and γ-glutamyltransferase levels and the decrease in calcium. The implementation of clinical chemistry is probably most helpful when the medical supportive care implemented at the Ebola treatment unit allows for correction of biochemistry derangements and on-site clinical chemistry analyzers can be used to monitor electrolyte balance.

In VVER-TOI reactor plant design the primary water chemistry has been improved considering operation experience of VVER reactor plants and a possibility of RP operation under load-follow modes from the viewpoint of meeting the following requirements: - suppression of generation of oxidizing radiolytic products under power operation; - assurance of corrosion resistance of structural materials of equipment and pipelines throughout the NPP design service life; - minimization of deposits on surfaces of the reactor core fuel rods and on heat exchange surface of steam generators; - minimization of accumulation of activated corrosion products; - minimization of the amount of radioactive processing waste. In meeting these requirements an important role is devoted to suppression of generation of oxidizing radiolytic products owing to accumulation of hydrogen in the primary coolant. At NPP with VVER-1000 reactor the ammonia-potassium water chemistry is used wherein the hydrogen accumulation is provided at the expense of ammonia proportioning. Usage of ammonia leads to generation of additional amount of radioactive processing waste and to increased irregularity of maintaining the water chemistry under the daily load-follow modes. In VVER TOI design the primary water chemistry is improved by replacing the proportioning of ammonia with the proportioning of gaseous hydrogen. Different process schemes were considered that provide for a possibility of hydrogen accumulation and maintaining owing to direct proportioning of gaseous hydrogen. The obtained results showed that transition to the potassium water chemistry

JBA Chevallier is first known for his publication in 1850 of his book on falsifications. But he had also a major role for the opening of the pharmacy world to toxicological and Public Health issues, through the founding in 1825, and the management for more than 50 years, of the Journal de chimie médicale, de pharmacie et de toxicologie (Journal of Medical Chemistry, of Pharmacy and of Toxicology). The purpose of the present study has been to look at the evolution of that publication over the years and to compare its content with the reference pharmaceutical journal at that time : the Journal de pharmacie et de chimie (Journal of Pharmacy and Chemistry). One can observe that the editorial lines of both journals will progressively diverge from each other, but Chevallier remained strongly connected with pharmacy, his journal merging finally in 1876 with the Répertoire de pharmacie (Index of Pharmacy).

Constitutional dynamic chemistry: bridge from supramolecular chemistry to adaptive chemistry.

Science.gov (United States)

Lehn, Jean-Marie

2012-01-01

Supramolecular chemistry aims at implementing highly complex chemical systems from molecular components held together by non-covalent intermolecular forces and effecting molecular recognition, catalysis and transport processes. A further step consists in the investigation of chemical systems undergoing self-organization, i.e. systems capable of spontaneously generating well-defined functional supramolecular architectures by self-assembly from their components, thus behaving as programmed chemical systems. Supramolecular chemistry is intrinsically a dynamic chemistry in view of the lability of the interactions connecting the molecular components of a supramolecular entity and the resulting ability of supramolecular species to exchange their constituents. The same holds for molecular chemistry when the molecular entity contains covalent bonds that may form and break reversibility, so as to allow a continuous change in constitution by reorganization and exchange of building blocks. These features define a Constitutional Dynamic Chemistry (CDC) on both the molecular and supramolecular levels.CDC introduces a paradigm shift with respect to constitutionally static chemistry. The latter relies on design for the generation of a target entity, whereas CDC takes advantage of dynamic diversity to allow variation and selection. The implementation of selection in chemistry introduces a fundamental change in outlook. Whereas self-organization by design strives to achieve full control over the output molecular or supramolecular entity by explicit programming, self-organization with selection operates on dynamic constitutional diversity in response to either internal or external factors to achieve adaptation.The merging of the features: -information and programmability, -dynamics and reversibility, -constitution and structural diversity, points to the emergence of adaptive and evolutive chemistry, towards a chemistry of complex matter.

Brown, Andrew N; Gilbert, Ben

2014-01-01

Limited human resources are widely recognised as an impediment to achieving the health-related Millennium Development Goals in Pacific Island Countries, with the availability of medical supplies and suitably trained health personnel crucial to ensuring a well-functioning medical supply chain. This paper presents our findings as we seek to answer the research question 'What factors influence the availability of medical supplies within the health facilities of Papua New Guinea?' We used a qualitative, triangulated strategy using semi-structured interviews, workplace observation and semi-structured focus groups. The parallel use of the interview tool and workplace observation tool allowed identification of 'know-do' gaps between what the interviewee said they did in their work practices, and the actual evidence of these practices. Focus groups provided further opportunities for raising and elaborating issues. During 2 weeks of data collection we conducted 17 interviews and 15 observational workplace surveys in 15 facilities. Sixteen health personnel participated in 3 focus groups across 2 provinces and one district. An array of medical supply issues across all levels of the medical supply chain were revealed, including standard operating procedures, facilities, transport, emergency medical kits, the cold chain and record keeping. The influence of health worker training and competency was found to be common across all of these issues. The factors influencing the availability of medical supplies in PNG consist of a range of interrelating issues, consisting of both simple and complex problems involving the different levels and cadres of workers within the medical supply chain. Health systems sustainability theory suggests that a coordinated approach which addresses the inter-related nature of these issues, led by the PNG government and supported by suitable development partners, will be required for sustainable health systems change to occur. These changes are necessary

Learning to care: medical students’ reported value and evaluation of palliative care teaching involving meeting patients and reflective writing

2016-11-01

Full Text Available Abstract Background Over recent years there has been an increase in teaching of both palliative care and reflective practice in UK medical schools. The palliative care teaching at the University of Cambridge School of Clinical Medicine is multi-faceted and involves students writing reflective essays after individually meeting patients approaching the end of life during their final year general practice and hospital medicine placements. This paper draws on two studies examining this teaching element to analyse what the students found valuable about it and to comment on the practice of meeting patients and subsequent reflective writing. Methods Two studies have explored students’ perceptions of these course components. The first was a thematic analysis of 234 reflective essays from 123 students written in 2007-2008, including examining what students wrote about the exercise itself. The second project involved a semi-structured questionnaire that students completed anonymously; this paper reports on the free text elements of that study [sample size =107]. Since similar themes were found in both studies, the coding structures from each project were compared and combined, enabling triangulation of the findings around what the students found valuable from the palliative care teaching involving meeting patients and reflective writing. Results Overall, students reported that these components of the palliative care teaching are valuable. Four main themes were identified as aspects that students valued: (1 dedicated time with patients, (2 learning about wider elements of treatment and holistic care, (3 practicing communication skills, and (4 learning about themselves through reflective writing. Some students expressed a dislike for having to formally write a reflective essay. Conclusion It is possible to arrange for all of the medical students to individually meet at least two patients receiving palliative or end of life care. Students found these

Against a backdrop of a struggling economic and regulatory climate, pharmaceutical companies have recently been forced to develop new ways to provide more efficient technology to meet the demands of a competitive drug industry. This issue, coupled with an increase in patent legislation and a rising generics market, makes these themes common issues in the growth of drug development. As a consequence, the importance of process chemistry and scale-up has never been more under the spotlight. Future Medicinal Chemistry wishes to share the thoughts and opinions of a variety of experts from this field, discussing issues concerning the use of flow chemistry to optimize drug development, the potential regulatory and environmental challenges faced with this, and whether the academic and industrial sectors could benefit from a more harmonized system relevant to process chemistry.

Innovations in medical education to meet workforce challenges.

Science.gov (United States)

2000-01-01

The winds of change world-wide have swept medical education in the last fifteen years. Today, Australia's medical students are older and drawn from more diverse socio-economic, ethnic and geographic backgrounds than twenty years ago, and there is now an equal mix of men and women in medical school. Admission policies have been rewritten to broaden access with a range of entry options now available including direct entry from high school and graduate entry following a first degree. Curricula have been revised and modes of learning transformed. This paper describes these changes and discusses the implications for medical schools and for planning the future workforce.

In developed countries, the importance of water as a resource and problems derived from its scarcity has led to growing social and legislative demands. As a consequence, in the last 30 years, new fields of research have opened in a search for more efficient water treatment methods. This is the case of the advanced oxidation techniques (AOTs) and their application to nonbiodegradable contaminants, which can otherwise be removed from water, but not eliminated. Fast development of research in this field has encouraged chemists, chemical engineers and related professionals to meet and debate their findings and plan new strategies for the future, working toward evermore efficient methods of wastewater treatment wherever needed. The same can be said of gaseous effluents, as emission limits for organic air pollution become stricter. Volatile organic compounds (VOCs) pose an environmental and health threat, which can be treated by adsorption, incineration, condensation, etc., or be completely destroyed by chemical methods, such as the very promising gas-phase photocatalytic air pollution treatment. The SPEA Meetings have been held against this background, particularly this fourth one, where scientists assembled to present and debate their latest achievements in low-cost treatment technologies for wastewater, gaseous effluents and polluted soils. This Special Issue of Catalysis Today was compiled from the scientific reports generated by the congress, and includes a selection of some of the most interesting work presented at the meeting. The 34-member Scientific Committee were from 11 different countries (Argentina, Chile, Finland, France, Germany, Greece, Italy, Slovakia, Spain, Switzerland, and the USA). One hundred and thirty-five delegates from 22 different countries attended the congress (representing 368 authors). One hundred and thirty-eight communications were presented, 45 oral presentations and 93 posters. Three plenary lectures, one round table and two poster

The concept of an advanced water chemistry diagnosis system for detection of anomalies and preventive maintenance of system components is proposed and put into a concrete form. Using the analogy to a medical inspection system, analyses of water chemistry change will make it possible to detect symptoms of anomalies in system components. Then, correlations between water chemistry change and anomaly occurrence in the components of the BWR primary cooling system are analyzed theoretically. These fragmentary correlations are organized and reduced to an algorithm for the on-line diagnosis system using on-line monitoring data, pH and conductivity. By using actual plant data, the on-line diagnosis model system is verified to be applicable for early and automatic finding of the anomaly cause and for timely supply of much diagnostic information to plant operators.

Medical biochemistry is the usual name for clinical biochemistry or clinical chemistry in Serbia, and medical biochemist is the official name for the clinical chemist (or clinical biochemist). This is the largest sub-discipline of the laboratory medicine in Serbia. It includes all aspects of clinical chemistry, and also laboratory hematology with coagulation, immunology, etc. Medical biochemistry laboratories in Serbia and medical biochemists as a profession are part of Health Care System and their activities are regulated through: the Health Care Law and rules issued by the Chamber of Medical Biochemists of Serbia. The first continuous and organized education for Medical Biochemists (Clinical Chemists) in Serbia dates from 1945, when the Department of Medical Biochemistry was established at the Pharmaceutical Faculty in Belgrade. In 1987 at the same Faculty a five years undergraduate study program was established, educating Medical Biochemists under a special program. Since the academic year 2006/2007 the new five year undergraduate (according to Bologna Declaration) and four-year postgraduate program according to EC4 European Syllabus for Postgraduate Training in Clinical Chemistry and Laboratory Medicine has been established. The Ministry of Education and Ministry of Public Health accredited these programs. There are four requirements for practicing medical biochemistry in the Health Care System: University Diploma of the Faculty of Pharmacy (Study of Medical Biochemistry), successful completion of the professional exam at the Ministry of Health after completion of one additional year of obligatory practical training in the medical biochemistry laboratories, membership in the Serbian Chamber of Medical Biochemists and licence for skilled work issued by the Serbian Chamber of Medical Biochemists. In order to present laboratory medical biochemistry practice in Serbia this paper will be focused on the following: Serbian national legislation, healthcare services

Evolving and changing undergraduate medical curricula raise concerns that there will no longer be a place for basic sciences. National and international trends show that 5-year programmes with a pre-requisite for school chemistry are growing more prevalent. National reports in Ireland show a decline in the availability of school chemistry and physics. This observational cohort study considers if the basic sciences of physics, chemistry and biology should be a prerequisite to entering medical school, be part of the core medical curriculum or if they have a place in the practice of medicine. Comparisons of means, correlation and linear regression analysis assessed the degree of association between predictors (school and university basic sciences) and outcomes (year and degree GPA) for entrants to a 6-year Irish medical programme between 2006 and 2009 (n = 352). We found no statistically significant difference in medical programme performance between students with/without prior basic science knowledge. The Irish school exit exam and its components were mainly weak predictors of performance (-0.043 ≥ r ≤ 0.396). Success in year one of medicine, which includes a basic science curriculum, was indicative of later success (0.194 ≥ r (2) ≤ 0.534). University basic sciences were found to be more predictive than school sciences in undergraduate medical performance in our institution. The increasing emphasis of basic sciences in medical practice and the declining availability of school sciences should mandate medical schools in Ireland to consider how removing basic sciences from the curriculum might impact on future applicants.

We analyzed Twitter activity generated from the 2013-2016 American Society of Breast Surgeons Annual Meetings. The Symplur Signals database was used to determine number of tweets, tweets per user, and impressions for each meeting. The number of unique physicians, patients/caregivers/advocates, and industry participants was determined. Physician tweeters were cross-referenced with membership and attendance rosters. Tweet transcripts were analyzed for content and tweets were categorized as either scientific, social, administrative, industry promotion, or irrelevant. From 2013 to 2016, the number of tweets increased by 600 %, the number of Twitter users increased by 450 %, and the number of physician tweeters increased by 457 %. The number of impressions (tweets × followers) increased from more than 3.5 million to almost 20.5 million, an increase of 469 %. The majority of tweets were informative (70-80 %); social tweets ranged from 13 to 23 %. A small percentage (3-6 %) of tweets were related to administrative matters. There were very few industry or irrelevant tweets. Twitter social media use at the American Society of Breast Surgeons annual meeting showed a substantial increase during the time period evaluated. The use of Twitter during professional meetings is a tremendous opportunity to share information. The authors feel that medical conference organizers should encourage Twitter participation and should be educating attendees on the proper use of Twitter.

Tc Chemistry in HLW: Role of Organic Complexants

International Nuclear Information System (INIS)

Hess, Nancy S.; Conradsen, Steven D.

2003-01-01

Tc complexation with organic compounds in tank waste plays a significant role in the redox chemistry of Tc and the partitioning of Tc between the supernatant and sludge components in waste tanks. These processes need to be understood so that strategies to effectively remove Tc from high-level nuclear waste prior to waste immobilization can be developed and so that long-term consequences of Tc remaining in residual waste after sludge removal can be evaluated. Only limited data on the stability of Tc-organic complexes exists and even less thermodynamic data on which to develop predictive models of Tc chemical behavior is available. To meet these challenges we are conducting a research program to study to develop thermodynamic data on Tc-organic complexation over a wide range of chemical conditions. We will attempt to characterize Tc-speciation in actual tank waste using state-of-the-art analytical organic chemistry, separations, and speciation techniques to validate our model. On the basis of such studies we will develop credible model of Tc chemistry in HLW that will allow prediction of Tc speciation in tank waste and Tc behavior during waste pretreatment processing and in waste tank residuals

2010 Gordon Research Conference On Radiation Chemistry

International Nuclear Information System (INIS)

Orlando, Thomas

2010-01-01

The 2010 Gordon Conference on Radiation Chemistry will present cutting edge research regarding the study of radiation-induced chemical transformations. Radiation Chemistry or 'high energy' chemistry is primarily initiated by ionizing radiation: i.e. photons or particles with energy sufficient to create conduction band electrons and 'holes', excitons, ionic and neutral free radicals, highly excited states, and solvated electrons. These transients often interact or 'react' to form products vastly different than those produced under thermal equilibrium conditions. The non-equilibrium, non-thermal conditions driving radiation chemistry exist in plasmas, star-forming regions, the outer solar system, nuclear reactors, nuclear waste repositories, radiation-based medical/clinical treatment centers and in radiation/materials processing facilities. The 2010 conference has a strong interdisciplinary flavor with focus areas spanning (1) the fundamental physics and chemistry involved in ultrafast (atto/femtosecond) energy deposition events, (2) radiation-induced processes in biology (particularly spatially resolved studies), (3) radiation-induced modification of materials at the nanoscale and cosmic ray/x-ray mediated processes in planetary science/astrochemistry. While the conference concentrates on fundamental science, topical applied areas covered will also include nuclear power, materials/polymer processing, and clinical/radiation treatment in medicine. The Conference will bring together investigators at the forefront of their field, and will provide opportunities for junior scientists and graduate students to present work in poster format or as contributors to the Young Investigator session. The program and format provides excellent avenues to promote cross-disciplinary collaborations.

Fission gas release and fuel rod chemistry related to extended burnup

International Nuclear Information System (INIS)

1993-04-01

The purpose of the meeting was to review the state of the art in fission gas release and fuel rod chemistry related to extended burnup. The meeting was held in a time when national and international programmes on water reactor fuel irradiated in experimental reactors were still ongoing or had reached their conclusion, and when lead test assemblies had reached high burnup in power reactors and been examined. At the same time, several out-of-pile experiments on high burnup fuel or with simulated fuel were being carried out. As a result, significant progress has been registered since the last meeting, particularly in the evaluation of fuel temperature, the degradation of the global thermal conductivity with burnup and in the understanding of the impact on fission gas release. Fifty five participants from 16 countries and one international organization attended the meeting. 28 papers were presented. A separate abstract was prepared for each of the papers.

Chemistry control challenges in a supercritical water-cooled reactor

International Nuclear Information System (INIS)

Guzonas, David; Tremaine, Peter; Jay-Gerin, Jean-Paul

2009-01-01

The long-term viability of a supercritical water-cooled reactor (SCWR) will depend on the ability of designers to predict and control water chemistry to minimize corrosion and the transport of corrosion products and radionuclides. Meeting this goal requires an enhanced understanding of water chemistry as the temperature and pressure are raised beyond the critical point. A key aspect of SCWR water chemistry control will be mitigation of the effects of water radiolysis; preliminary studies suggest markedly different behavior than that predicted from simple extrapolations from conventional water-cooled reactor behavior. The commonly used strategy of adding excess hydrogen at concentrations sufficient to suppress the net radiolytic production of primary oxidizing species may not be effective in an SCWR. The behavior of low concentrations of impurities such as transition metal corrosion products, chemistry control agents, anions introduced via make-up water or from ion-exchange resins, and radionuclides (e.g., 60 Co) needs to be understood. The formation of neutral complexes increases with temperature, and can become important under near-critical and supercritical conditions; the most important region is from 300-450 C, where the properties of water change dramatically, and solvent compressibility effects exert a huge influence on solvation. The potential for increased transport and deposition of corrosion products (active and inactive), leading to (a) increased deposition on fuel cladding surfaces, and (b) increased out-of-core radiation fields and worker dose, must be assessed. There are also significant challenges associated with chemistry sampling and monitoring in an SCWR. The typical methods used in current reactor designs (grab samples, on-line monitors at the end of a cooled, depressurized sample line) will be inadequate, and in-situ measurements of key parameters will be required. This paper describes current Canadian activities in SCWR chemistry and chemistry

Britton, Melanie M

2010-11-01

Magnetic resonance imaging (MRI) has long been recognized as one of the most important tools in medical diagnosis and research. However, MRI is also well placed to image chemical reactions and processes, determine the concentration of chemical species, and look at how chemistry couples with environmental factors, such as flow and heterogeneous media. This tutorial review will explain how magnetic resonance imaging works, reviewing its application in chemistry and its ability to directly visualise chemical processes. It will give information on what resolution and contrast are possible, and what chemical and physical parameters can be measured. It will provide examples of the use of MRI to study chemical systems, its application in chemical engineering and the identification of contrast agents for non-clinical applications. A number of studies are presented including investigation of chemical conversion and selectivity in fixed-bed reactors, temperature probes for catalyst pellets, ion mobility during tablet dissolution, solvent dynamics and ion transport in Nafion polymers and the formation of chemical waves and patterns.

Chemistry educators often examine and implement various instructional techniques, such as mentoring programs, to advance learning objectives and to equip students with analytical and technical skills, as well as the skills required of chemical science professionals. Student organizations, such as an American Chemical Society Student Affiliates (SA) chapter, can create a learning environment for undergraduates by engaging them in activities that develop communication, teamwork and inquiry, analysis, and problem-solving skills within a real-world setting. The environment is student-based, has personal meaning for the learner, emphasizes a process-and-product orientation, and emphasizes evaluation. Participation in SAs enhance the traditional chemistry curriculum, complementing the learning goals and meeting learning objectives that might not otherwise be addressed in the curriculum. In this article we discuss how SA chapters enhance the educational experience of undergraduate chemical science students, help develop new chemistry professionals, and shape enthusiastic and committed future chemical science leaders.

From hot atom chemistry to epithermal chemistry

International Nuclear Information System (INIS)

Roessler, K.

2004-01-01

The rise and fall of hot atom chemistry (HAC) over the years from 1934 to 2004 is reviewed. Several applications are discussed, in particular to astrophysics and the interaction of energetic ions and atoms in space. Epithermal chemistry (ETC) is proposed to substitute the old name, since it better fits the energy range as well as the non-thermal and non-equilibrium character of the reactions. ETC also avoids the strong connexion of HAC to nuclear chemistry and stands for the opening of the field to physical chemistry and astrophysics. (orig.)

2011-07-01

The graduate-level textbook Chemistry of High-Energy Materials provides an introduction to and an overview of primary and secondary (high) explosives as well as propellant charges, rocket propellants and pyrotechnics. After a brief historical overview, the main classes of energetic materials are discussed systematically. Thermodynamic aspects, as far as relevant to energetic materials, are discussed, as well as modern computational approaches to predict performance and sensitivity parameters. The most important performance criteria such as detonation velocity, detonation pressure and heat of explosion, as well as the relevant sensitivity parameters suc as impact and friction sensitivity and electrostatic discharge sensitivity are explored in detail. Modern aspects of chemical synthesis including lead-free primary explosives and high-nitrogen compounds are also included in this book together with a discussion of high-energy materials for future defense needs. The most important goal of this book, based on a lecture course which has now been held at LMU Munich for over 12 years, is to increase knowledge and know-how in the synthesis and safe handling of high-energy materials. Society needs now as much as ever advanced explosives, propellant charges, rocket propellants and pyrotechnics to meet the demands in defense and engineering. This book is first and foremost aimed at advanced students in chemistry, engineering and materials sciences. However, it is also intended to provide a good introduction to the chemistry of energetic materials and chemical defense technology for scientists in the defense industry and government-run defense organizations.

Water chemistry at RBMK plants: Problems and solutions

International Nuclear Information System (INIS)

Mamet, V.; Yurmanov, V.

2002-01-01

After around 15 years of operation RBMK-1000 units undergo a major refit, which includes safety system upgrading, fuel tube replacement, etc. The above upgrading has created problems for water chemistry. In particular, in late 80's in-core insertion time of the portion of control rods was reduced 10-fold thanks to a transfer from water to filming cooling of scram channels. Scram channels are cooled with inner surface water film cooling and nitrogen is injected into heads via special pipelines. Such cooling system modernization ensures fast insertion of absorber rods. The above upgrade intensified nitric acid radiolytic generation in water coolant and pH 25 value shift to acid conditions (up to 4.5). The results of corrosion tests in such conditions proved the necessity to improve water chemistry to ensure corrosion protection of scram/control rod and circuit components, especially those made out of aluminium alloy. Since 1990 the new revision of the RBMK-1000 water chemistry standard specified the new normal operational limit and action levels for possible temporary deviations of pH 25 value. RBMK plant specific measures were implemented at RBMK plants to meet the above requirements of the 1990 revision of the RBMK-1000 water chemistry standard. Clean-up systems of the above circuit were upgraded to ensure intensive absorption of nitric acid from water and pH 25 maintenance in a slightly acid area. (authors)

Ethical issues in medical research in the developing world: a report on a meeting organised by Fondation Mérieux.

Science.gov (United States)

Perrey, Christophe; Wassenaar, Douglas; Gilchrist, Shawn; Ivanoff, Bernard

2009-08-01

This paper reports on a multidisciplinary meeting held to discuss ethical issues in medical research in the developing world. Many studies, including clinical trials, are conducted in developing countries with a high burden of disease. Conditions under which this research is conducted vary because of differences in culture, public health, political, legal and social contexts specific to these countries. Research practices, including standards of care for participants, may vary as a result. It is therefore not surprising that ethical issues emerge. This meeting sought to identify and discuss these issues from the perspectives of the many actors in such research, including community representatives, with a view to finding ethical and pragmatic solutions to these issues. Dialogue between these actors was also promoted, with a view to identifying the need to develop such dialogue in future. Drawing from the experiences of the speakers, the colloquium attempted to outline some answers to several key questions characterising the field today. Experiences related to epidemiologic research, vaccine trials, drug trials, diagnostic tests and to some fundamental ethical issues in health research. Speakers were from different countries, disciplines and professions. The meeting provided a forum for consultation and debate between different ethics actors. Both encouraging findings and challenges emerged.

Baseline levels of individual liver chemistry tests were most important for predicting their own elevations during the trials. High bilirubin levels at baseline were not uncommon and were associated with a high risk of developing biochemical Hy’s law cases. Baseline γ-glutamyltransferase (GGT level appeared to have some predictive value, but did not increase predictability beyond using established liver chemistry tests.Conclusion: It is possible to predict which patients are at a higher risk of developing liver chemistry signals using pretreatment (baseline data. Derived knowledge from such predictions may allow proactive and targeted risk management, and the type of analysis described here could help determine whether new biomarkers offer improved performance over established ones.Keywords: bilirubin, Hy’s Law, ALT, GGT, baseline, prediction

Preparing for a Global Scientific Workforce: Lessons Learned by the Chemistry Community

Baranovic, M.; Nameroff, T.

2005-12-01

Globalization has significant implications for science, science education, and the workforce. Flows of capital and knowledge are altering patterns of economic and technological development. Technology is allowing science to be conducted in real time on a global scale. International connections and mobility are increasing worldwide. At the same time science is becoming a truly global endeavor, the convergence of disciplines suggests that scientists from different backgrounds can learn from each other's experiences in addressing these challenges and opportunities. This presentation reviews some of the impacts of globalization on the chemically related sciences, students, and profession. As a result of globalization, today's practitioners of chemistry need an ever-expanding skill set to succeed. In addition to a strong command of the basic principles of chemistry, students and practitioners need to know how to work on multicultural teams, have knowledge of other languages, and be able to communicate effectively. The American Chemical Society (ACS) is coming to terms with and responding to changes in the nature of chemistry and its practice. This presentation will explore some of the innovative efforts of ACS to meet the challenges for chemistry in an era of globalization. The Earth and space sciences community may benefit from the chemistry community's "lessons learned."

2010-01-01

Twice-yearly meetings of The British Society of Rehabilitation Medicine (BSRM) take place at which posters and free papers are generated, as abstracts, to present novel research findings, audits and case reports. The aim of this study was to evaluate the academic value of these meetings, by determining the subsequent rate of publication in peer-reviewed journals of abstracts presented. This was compared to the publication rate of other European medical specialist society meetings. The authors used MEDLINE, PubMed and Google Scholar search engines to look for publication of abstracts presented at BSRM meetings within peer-reviewed journals over a 7-year period (2000-2006). The abstracts were categorised into sub-groups (original study, audit, review, case report and service description) to determine which type was more likely to be published. The above databases were used also to extract studies on publication rate of other medical specialties in Europe. In 7 years, a total of 251 abstracts (of which 152 are original studies) have been presented as free papers or posters in a total of 13 meetings. The publication rate for the described study categories were: total 34%, original study 52%, review 50%, case report 5%, audit 0% and service description 0%. Publication rates from other specialist meetings in Europe range from 10% to 70%. The average publication rate for an abstract submitted to a BSRM meeting is 34% for any abstract and 52% for an original study suggesting that the meeting is generating abstracts of comparable academic interest to other specialist societies.

Advanced chemistry management system to optimize BWR chemistry control

International Nuclear Information System (INIS)

Maeda, K.; Nagasawa, K.

2002-01-01

BWR plant chemistry control has close relationships among nuclear safety, component reliability, radiation field management and fuel integrity. Advanced technology is required to improve chemistry control [1,3,6,7,10,11]. Toshiba has developed TACMAN (Toshiba Advanced Chemistry Management system) to support BWR chemistry control. The TACMAN has been developed as response to utilities' years of requirements to keep plant operation safety, reliability and cost benefit. The advanced technology built into the TACMAN allows utilities to make efficient chemistry control and to keep cost benefit. TACMAN is currently being used in response to the needs for tools those plant chemists and engineers could use to optimize and identify plant chemistry conditions continuously. If an incipient condition or anomaly is detected at early stage, root causes evaluation and immediate countermeasures can be provided. Especially, the expert system brings numerous and competitive advantages not only to improve plant chemistry reliability but also to standardize and systematize know-how, empirical knowledge and technologies in BWR chemistry This paper shows detail functions of TACMAN and practical results to evaluate actual plant.

The professional duties of the specialists in clinical chemistry differ from country to country in Europe. One of the main goals of the Strategic Plan of the Forum of the European Societies of Clinical Chemistry and Laboratory Medicine (FESCC; IFCC-Europe) is to promote a high scientific and professional standard in the field of clinical chemistry and laboratory medicine in Europe. This can be stimulated by the knowledge of the local conditions in each country and by striving towards a strong and harmonised position in all the European countries. In order to enhance the knowledge of the managerial situation of the specialists in clinical chemistry in Europe, FESCC launched a survey in September 2000. This survey provides information about the position of the specialists in clinical chemistry in the various disciplines in the medical laboratories and in hospitals, and about the advisory tasks and the managerial education during the post-graduate training in clinical chemistry. Of the 35 FESCC member countries 33 have participated in the survey (94%). The results show a rather heterogeneous situation in Europe caused by the local historical developments, the differences in academic background and the relative numbers of private and physicians' office laboratories. Large differences exist between the European countries in the disciplines of laboratory medicine that are headed by a specialist in clinical chemistry. In the different countries the clinical chemistry laboratories are headed by specialists in clinical chemistry in between 20% and 100% of the laboratories. The haematology, immunology, microbiology, therapeutic drug monitoring, molecular biology and haemostasis laboratories and departments of blood banking are headed by specialists in clinical chemistry in between 0% and 100% of the laboratories. The responsibilities for the various managerial tasks of the specialists in clinical chemistry show no uniformity in Europe. In the majority of the countries the

Water chemistry control at FBTR

International Nuclear Information System (INIS)

Panigrahi, B.S.; Jambunathan, D.; Suresh Kumar, K.V.; Ramanathan, V.; Srinivasan, G.; Ramalingam, P.V.

Condenser cooling and service water systems together serve as the cooling water system of Fast Breeder Test Reactor (FBTR). Palar river water serves as the make-up to the cooling water system. Initially, the service water system alone was commissioned in phases depending upon the arrival of auxiliary equipments at site. During this period, the water was not treated chemically and it also inadvertently remained stagnant for some time in some systems. Thereafter, a threshold chemical treatment was started. However, pin-hole leaks and reduced flow through the heat exchangers were observed and therefore chemical cleaning of headers was done and small diameter pipelines were replaced. Following this a full fledged chemistry control with proprietary formulations was initiated. Later the condenser cooling system was commissioned and the chemical treatment was reviewed. With adoption of improved monitoring methodology and treatment formulation satisfactory corrosion control (< 3 mpy) with minimum deposition problem in this system could be achieved. The primary coolant (primary sodium) of FBTR transfers the nuclear heat to the secondary coolant (secondary sodium) that in turn transfers heat to water in Once Through Steam Generator (OTSG) to generate superheated steam (480 deg C at 125 bar). Efficient water chemistry control plays the vital role in minimizing corrosion related failures of steam generator tubes and ensuring steam generator tube integrity. Therefore, the technical specifications of chemistry parameters of feed/steam water at FBTR are made very stringent to maintain the purity of water at the best attainable level. To meet this stringent feed water and steam quality specifications, online monitoring techniques have been employed in the steam/water circuit to get continuous information about the purity. These monitors have helped significantly in achieving the required feed water quality and running the steam generator for more than 25000 hours without any tube

Documentation of medical findings in radiation workers in the GDR to meet the requirements of ICRP publication 26

International Nuclear Information System (INIS)

Wolff, H.R.; Neumeister, K.

1979-01-01

Based on ICRP Publication 26, the future organization of the medical surveillance system for radiation workers in the GDR is considered in this paper. These radiation workers will also in future be medically supervised by means of pre-employment and routine examinations. It is considered necessary to have as extensive a registration as possible of information on medical examinations, working place analyses and incidents. Such data have to be collected and stored to be compared with other national and international projects (e.g. in the field of occupational health). In addition, they should permit epidemiological studies to be internationally co-ordinated. For this purpose, a documentation system has been prepared in the German Democratic Republic which is based on GDR experiences and makes it possible to specify the requirements of ICRP Publication 26. This system forms a new basis for mass examinations of occupationally exposed persons. Uniform examination methods tailored to meet the task of assuring occupational health in the GDR will be introduced. The documentation cards are meant to be used as clear-text cards suited for automatic reading by optical character recognition. The examination form consists of ten parts and comprises all details from working place situation to medical findings to laboratory results. It is felt that this new documentation system permits registration of all relevant data required for the effective radiation protection of man. On the basis of this documentation of findings, participation is scheduled in the respective international IAEA programmes and the studies proposed by the ICRP for problems of radiation-induced carcinogenesis and radiogenetics

This document was prepared to meet FCR&D level 3 milestone M3FT-16IN030104052, “continue the study of the short chain compounds,” and, “ study the radiolysis of the non-symmetrical DGA (D3DODGA)….,” under the Radiation Chemistry FCR&D work package. Toward these goals, the short chain DGA, tetraethyldiglycolamide (TEDGA) was investigated for its hydrolytic stability in HNO3 solution, with comparisons to the less oxidizing mineral acid HCl. Initial gamma-irradiations were also performed on DGA solutions, to inform a more detailed investigation of several short chain compounds anticipated for FY17. The hydrolytic and radiolysis behavior of TEDGA is of interest for two reasons. First, previous long chain DGA radiolysis was conducted in dodecane solution since the long chain compounds are soluble in that diluent, and new radiation chemistry is expected in the aqueous environment due to reactions with •OH radical. The second reason is that this water-soluble DGA has been proposed for use as a stripping or holdback agent in both European and American fuel cycle scenarios. Therefore, this work was performed in collaboration Forschungszentrum Jülich (FZJ), and the European SACSESS program. Additionally, results are presented here regarding the radiation of chemistry the non-symmetrical DGA didodecyldioctyldiglycolamide (D3DODGA), for comparison to previous work with symmetrical DGAs such as TODGA and TEHDGA. This was also conducted in collaboration with researchers in the SACSESS program.

Guze, Phyllis A

2015-01-01

Medical education is rapidly changing, influenced by many factors including the changing health care environment, the changing role of the physician, altered societal expectations, rapidly changing medical science, and the diversity of pedagogical techniques. Changes in societal expectations put patient safety in the forefront, and raises the ethical issues of learning interactions and procedures on live patients, with the long-standing teaching method of "see one, do one, teach one" no longer acceptable. The educational goals of using technology in medical education include facilitating basic knowledge acquisition, improving decision making, enhancement of perceptual variation, improving skill coordination, practicing for rare or critical events, learning team training, and improving psychomotor skills. Different technologies can address these goals. Technologies such as podcasts and videos with flipped classrooms, mobile devices with apps, video games, simulations (part-time trainers, integrated simulators, virtual reality), and wearable devices (google glass) are some of the techniques available to address the changing educational environment. This article presents how the use of technologies can provide the infrastructure and basis for addressing many of the challenges in providing medical education for the future.

Ojima, Iwao

2013-07-05

Over the last three decades, my engagement in "fluorine chemistry" has evolved substantially because of the multidisciplinary nature of the research programs. I began my research career as a synthetic chemist in organometallic chemistry and homogeneous catalysis directed toward organic synthesis. Then, I was brought into a very unique world of "fluorine chemistry" in the end of 1970s. I started exploring the interface of fluorine chemistry and transition metal homogeneous catalysis first, which was followed by amino acids, peptides, and peptidomimetics for medicinal chemistry. Since then, I have been exploring the interfaces of fluorine chemistry and multidisciplinary fields of research involving medicinal chemistry, chemical biology, cancer biology, and molecular imaging. This perspective intends to cover my fruitful endeavor in the exploration of fluorine chemistry at the multidisciplinary interface of chemistry and biology in a chronological order to show the evolution of my research interest and strategy.

Student selection: are the school-leaving A-level grades in biology and chemistry important?

Science.gov (United States)

Green, A; Peters, T J; Webster, D J

1993-01-01

This study determined the relationships of grades in A-level biology and chemistry with examination success or failure during the medical course. By inspection of medical student records, A-level grades at entry to medical school and examination performance were obtained for 128 (91%) of the students who sat their final MBBCh examination at the University of Wales College of Medicine in June 1988. The majority, 92 (72%), completed their medical school careers with no professional examination failures; 15 failed examinations just in the period up to 2nd MB; 11 failed examinations in the clinical period only and 10 failed examinations in both periods. Whereas grade achieved in A-level chemistry was not associated with undergraduate examination performance, students with a grade A or B in A-level biology were less likely to have problems than the others (21% compared with 47%; the difference of 26% has a 95% confidence interval of 7% to 44%). Specifically, there appears to be a strong relationship between a low grade in biology and difficulties in the preclinical examinations. Moreover, for those who have difficulties at this stage, this association continues later in the course.

Technetium Chemistry in HLW: Role of Organic Complexants

International Nuclear Information System (INIS)

Hess, Nancy J.; Blanchard, David L. Jr.; Campbell, James A.; Cho, Herman M.; Rai, Dhanpat Rai; Xia, Yuanxian; Conradson, Steven D.

Technetium complexation with organic compounds in tank waste plays a significant role in the redox chemistry of Tc and the partitioning of Tc between the supernatant and sludge components in waste tanks. These processes need to be understood so that strategies to effectively remove Tc from high-level nuclear waste prior to waste immobilization can be developed and so that longterm consequences of Tc remaining in residual waste after sludge removal can be evaluated. Only limited data on the stability of Tc-organic complexes exists, and even less thermodynamic data on which to develop predictive models of Tc chemical behavior is available. To meet these challenges, we present a research program to study Tc-speciation in actual tank waste using state-of-the-art analytical organic chemistry, separations, and speciation techniques. On the basis of such studies, we will acquire thermodynamic data for the identified Tc-organic complexes over a wide range of chemical conditions in order to develop credible models to predict Tc speciation in tank waste and Tc behavior during waste pretreatment processing and in waste tank residuals

Among wide application of radiation in the field of polymer chemistry, practices of polymerization, graft polymerization, bridging, etc. are introduced hereinafter. As for the radiation sources of radiation polymerization, in addition to the 60 Co-γ ray with long permeation distance which has been usually applied, electron beam accelerators with high energy, large current and high reliability have come to be produced, and the liquid phase polymerization by electron beam has attracted attention industrially. Concerning polymerizing reactions, explanations were given to electron beam polymerization under high dose rate, the polymerization in supercooling state or under high pressure, and emulsifying polymerization. As for radiation bridging, radiation is applied for the bridging of hydrogel, acceleration of bridging and improvement of radiation resistance. It is also utilized for reforming membranes by graft polymerization, and synthesis of polymers for medical use. Application of fixed enzymes in the medical field has been investigated by fixing various enzymes by low temperature γ-ray polymerization with glassy monomers such as HEMA. (Kobatake, H.)

From fundamental supramolecular chemistry to self-assembled nanomaterials and medicines and back again - how Sam inspired SAMul.

Science.gov (United States)

Smith, David K

2018-05-08

This feature article provides a personal insight into the research from my group over the past 10 years. In particular, the article explains how, inspired in 2005 by meeting my now-husband, Sam, who had cystic fibrosis, and who in 2011 went on to have a double lung transplant, I took an active decision to follow a more applied approach to some of our research, attempting to use fundamental supramolecular chemistry to address problems of medical interest. In particular, our strategy uses self-assembly to fabricate biologically-active nanosystems from simple low-molecular-weight building blocks. These systems can bind biological polyanions in highly competitive conditions, allowing us to approach applications in gene delivery and coagulation control. In the process, however, we have also developed new fundamental principles such as self-assembled multivalency (SAMul), temporary 'on-off' multivalency, and adaptive/shape-persistent multivalent binding. By targeting materials with applications in drug formulation and tissue engineering, we have discovered novel self-assembling low-molecular-weight hydrogelators based on the industrially-relevant dibenzylidenesorbitol framework and developed innovative approaches to spatially-resolved gels and functional multicomponent hybrid hydrogels. In this way, taking an application-led approach to research has also delivered significant academic value and conceptual advances. Furthermore, beginning to translate fundamental supramolecular chemistry into real-world applications, starts to demonstrate the power of this approach, and its potential to transform the world around us for the better.

Technetium chemistry is a young and developing field. Despite the limited knowledge of its chemistry, technetium is the workhorse for nuclear medicine. Technetium is also a significant environmental concern because it is formed as a byproduct of nuclear weapons production and fission-power generators. Development of new technetium radio-pharmaceuticals and effective environmental control depends strongly upon knowledge of basic technetium chemistry. The authors performed research into the basic coordination and organometallic chemistry of technetium and used this knowledge to address nuclear medicine and environmental applications. This is the final report of a three-year Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL)

Chemistry of Technetium

Omori, Takashi

2001-01-01

Since the late 1970's the coordination chemistry of technetium has been developed remarkably. The background of the development is obviously related to the use of technetium radiopharmaceuticals for diagnosis in nuclear medicine. Much attention has also been denoted to the chemical behavior of environmental 99 Tc released from reprocessing plants. This review covers the several aspects of technetium chemistry, including production of radioisotopes, analytical chemistry and coordination chemistry. In the analytical chemistry, separation of technetium, emphasizing chromatography and solvent extraction, is described together with spectrophotometric determination of technetium. In the coordination chemistry of technetium, a characteristic feature of the chemistry of Tc(V) complexes is referred from the view point of the formation of a wide variety of highly stable complexes containing the Tc=O or Tc≡N bond. Kinetic studies of the preparation of Tc(III) complexes using hexakis (thiourea) technetium(III) ion as a starting material are summarized, together with the base hydrolysis reactions of Tc(III), Tc(IV) and Tc(V) complexes.

This volume continues the series of congress publications with which the Deutsche Gesellschaft fuer Medizinische Physik has been completely documenting its annual meetings for some years. The meeting was aimed to show the complexity not only of the scientific specialty medical physics but also of the practical activities of medical physicists, or at least give some idea of it. The conference was centred on the following points: Possibilities of optimization and methods for re-examination of techniques used in X-ray diagnostics, nuclear diagnostics and ultrasonographic diagnostics; bases of dosimetry in practical radiotherapy, especially with a view to the plans to make gauging of therapeutical dosemeters compulsory; current state of neutron therapy and dosimetry; safety and constancy of irradiation devices in operation; planning and equipment of modern radiotherapy departments. Furthermore topics from medical optics and nuclearbiological research were dealt with. Reports were given on the clinical use of whole-body counters. Climatology and surgical research were marginally dealt with in two synoptical papers. Short reports on work currently under way completed the subject groups given and allowed insight into further topical fields of work of medical physicists in science and practice. Finally, the question of education received particular interest. (orig./MG) [de

Zimek, Z.; Przybytniak, G.; Kaluska, I.

2006-01-01

R(and)D studies in the field of radiation technology in Poland are mostly concentrated at the Institute of Nuclear Chemistry and Technology (INCT). The results of the INCT works on polymer and semiconductor modification have been implemented in various branches of national economy, particularly in industry and medicine. Radiation technology for polymer modification was implemented in the middle of the 1970-ties. Among others, the processes of irradiation and heat shrinkable products expansion have been developed. The transfer of this technology to Polish industry was performed in the middle of the 1980-ties. The present study aims at the formulation of new PE composites better suited to new generation of heat shrinkable products, for example, a new generation of hot-melt adhesives has been developed to meet specific requirements of customers. Modified polypropylene was used for the production of medical devices sterilized by radiation, especially disposable syringes, to overcome the low radiation resistance of the basic material. Modified polypropylene (PP-M) has been formulated at the INCT to provide material suitable for medical application and radiation sterilization process. Modification of semiconductor devices by EB was applied on an industrial scale since 1978 when the INCT and the LAMINA semiconductor factory successfully adopted that technology to improve specific semiconductor devices. This activity is continued on commercial basis where the INCT facilities served to contract irradiation of certain semiconductor devices according to the manufacturing program of the Polish factory and customers from abroad.

The ability to design reaction networks with high, but addressable complexity is a necessary prerequisite to make advanced functional chemical systems. Dynamic combinatorial chemistry has proven to be a useful tool in achieving complexity, however with some limitations in controlling it. Herein we introduce the concept of antiparallel chemistries, in which the same functional group can be channeled into one of two reversible chemistries depending on a controllable parameter. Such systems allow both for achieving complexity, by combinatorial chemistry, and addressing it, by switching from one chemistry to another by controlling an external parameter. In our design the two antiparallel chemistries are thiol-disulfide exchange and thio-Michael addition, sharing the thiol as the common building block. By means of oxidation and reduction the system can be reversibly switched from predominantly thio-Michael chemistry to predominantly disulfide chemistry, as well as to any intermediate state. Both chemistries operate in water, at room temperature, and at mildly basic pH, which makes them a suitable platform for further development of systems chemistry.

Marcoule institute for separation chemistry - ICSM. Scientific report 2007 - 2010

International Nuclear Information System (INIS)

2010-01-01

The mixed research unit 'Institute for Separation Chemistry' was created jointly by CEA, CNRS, University of Montpellier and Ecole Nationale superieure de Chimie de Montpellier has obtained authorisation to start experiments including a few grams of depleted uranium and natural thorium in January 2010. Last takeoff was from our theory group, who started in October 2009. But the unit 'Institut de Chimie separative de Marcoule' existed as a team scattered in several places in France since 2007. At that time, monthly meetings gathered people for full days of open discussion every month, as 'Point ICSM', where colleagues from R/D Departments of the centre of Marcoule composed half of the audience. Scientific activity began in 2007 with progressive joining of ICSM of team leaders, co-workers, technicians and students, today with 38 permanent staff and 29 nonpermanent scientists and students. Most of the staff joined ICSM after or before participating to the European practical summer school in Analytical and separation chemistry, hold yearly for a full week including practical sessions since the first edition 2006 in Montpellier. Resources in Uranium are scarce, if only the 235 isotope is used. Wastes related to nuclear energy production are potentially dangerous. Since fifty years, the chemistry associated to nuclear energy production always followed the principles of green chemistry. Permanent attention in devoted to closing the life-cycle of materials and fuel, minimize wastes and ascertain the acceptability by a society via knowledge of chemistry and physical chemistry involved in the chemistry used for separation. Developing knowledge in order to propose new separation processes is the central aim of the ICSM. Enlarging this central goal to surfaces of materials, sono-chemistry as an example of green chemistry, chemistry and physical chemistry specific to actinides complete this picture. Thus, the ICSM is devoted to chemistry at the service of the nuclear energy of

2014-10-13

Stimuli-responsive polymers play an important role in many biomedical technologies. Light responsive polymers are particularly desirable because the parameters of irradiated light and diverse photoactive chemistries produce a large number of combinations between functional materials and associated stimuli. This Review summarizes recent advances in utilizing photoactive chemistries in macromolecules for prospective use in biomedical applications. Special focus is granted to selection criterion when choosing photofunctional groups. Synthetic strategies to incorporate these functionalities into polymers and networks with different topologies are also highlighted herein. Prospective applications of these materials are discussed including programmable matrices for controlled release, dynamic scaffolds for tissue engineering, and functional coatings for medical devices. The article concludes by summarizing the state of the art in photoresponsive polymers for biomedical applications including current challenges and future opportunities.

Power plant cycle chemistry - a currently neglected power plant chemistry discipline

International Nuclear Information System (INIS)

Bursik, A.

2005-01-01

Power plant cycle chemistry seems to be a stepchild at both utilities and universities and research organizations. It is felt that other power plant chemistry disciplines are more important. The last International Power Cycle Chemistry Conference in Prague may be cited as an example. A critical review of the papers presented at this conference seems to confirm the above-mentioned statements. This situation is very unsatisfactory and has led to an increasing number of component failures and instances of damage to major cycle components. Optimization of cycle chemistry in fossil power plants undoubtedly results in clear benefits and savings with respect to operating costs. It should be kept in mind that many seemingly important chemistry-related issues lose their importance during forced outages of units practicing faulty plant cycle chemistry. (orig.)

The chemical research and development efforts related to the design and ultimate operation of molten-salt breeder reactor systems are concentrated on fuel- and coolant-salt chemistry, including the development of analytical methods for use in these systems. The chemistry of tellurium in fuel salt is being studied to help elucidate the role of this element in the intergranular cracking of Hastelloy N. Studies were continued of the effect of oxygen-containing species on the equilibrium between dissolved UF 3 and dissolved UF 4 , and, in some cases, between the dissolved uranium fluorides and graphite, and the UC 2 . Several aspects of coolant-salt chemistry are under investigation. Hydroxy and oxy compounds that could be formed in molten NaBF 4 are being synthesized and characterized. Studies of the chemistry of chromium (III) compounds in fluoroborate melts were continued as part of a systematic investigation of the corrosion of structural alloys by coolant salt. An in-line voltammetric method for determining U 4+ /U 3+ ratios in fuel salt was tested in a forced-convection loop over a six-month period. (LK)

From trace chemistry to single atom chemistry

International Nuclear Information System (INIS)

Adloff, J.P.

1993-01-01

Hot atom chemistry in the vast majority of experimental works deals with the trace amount of radioactive matters. Accordingly, the concept of trace chemistry is at the heart of hot atom chemistry. Some aspects of the chemistry at trace scale and at subtrace scale are presented together with the related problems of speciation and the complication which may arise due to the formation of radio colloids. The examples of 127 I(n,γ) 128 I and 132 Te (β - ) 132 I are shown, and the method based on radioactivity was used. The procedure of separating the elements in pitchblende is shown as the example of the chemistry of traces. 13 27 Al+ 2 4 He→ 0 1 n+ 15 30 P and 15 30 P→ 14 30 Si+e + +V are shown, and how to recognize the presence of radioactive colloids is explained. The formation of radiocolloids is by the sorption of a trace radioelement on pre-existing colloidal impurity or the self-condensation of monomeric species. The temporal parameters of the nature of reactions at trace concentration are listed. The examples of Class A and Class B reactions are shown. The kinetics of reactions at trace level, radon concentration, anthropogenic Pu and natural Pu in environment, the behavior of Pu atoms and so on are described. (K.I.)

RADIATION CHEMISTRY 2010 GORDON RESEARCH CONFERENCE JULY 18-23

Energy Technology Data Exchange (ETDEWEB)

Thomas Orlando

2010-07-23

The 2010 Gordon Conference on Radiation Chemistry will present cutting edge research regarding the study of radiation-induced chemical transformations. Radiation Chemistry or 'high energy' chemistry is primarily initiated by ionizing radiation: i.e. photons or particles with energy sufficient to create conduction band electrons and 'holes', excitons, ionic and neutral free radicals, highly excited states, and solvated electrons. These transients often interact or 'react' to form products vastly different than those produced under thermal equilibrium conditions. The non-equilibrium, non-thermal conditions driving radiation chemistry exist in plasmas, star-forming regions, the outer solar system, nuclear reactors, nuclear waste repositories, radiation-based medical/clinical treatment centers and in radiation/materials processing facilities. The 2010 conference has a strong interdisciplinary flavor with focus areas spanning (1) the fundamental physics and chemistry involved in ultrafast (atto/femtosecond) energy deposition events, (2) radiation-induced processes in biology (particularly spatially resolved studies), (3) radiation-induced modification of materials at the nanoscale and cosmic ray/x-ray mediated processes in planetary science/astrochemistry. While the conference concentrates on fundamental science, topical applied areas covered will also include nuclear power, materials/polymer processing, and clinical/radiation treatment in medicine. The Conference will bring together investigators at the forefront of their field, and will provide opportunities for junior scientists and graduate students to present work in poster format or as contributors to the Young Investigator session. The program and format provides excellent avenues to promote cross-disciplinary collaborations.

The 2009 Lindau Nobel Laureate Meeting: Roger Y. Tsien, Chemistry 2008.

Tsien, Roger Y

2010-01-13

American biochemist Roger Tsien shared the 2008 Nobel Prize in Chemistry with Martin Chalfie and Osamu Shimomura for their discovery and development of the Green Fluorescent Protein (GFP). Tsien, who was born in New York in 1952 and grew up in Livingston New Jersey, began to experiment in the basement of the family home at a young age. From growing silica gardens of colorful crystallized metal salts to attempting to synthesize aspirin, these early experiments fueled what would become Tsien's lifelong interest in chemistry and colors. Tsien's first official laboratory experience was an NSF-supported summer research program in which he used infrared spectroscopy to examine how metals bind to thiocyanate, for which he was awarded a $10,000 scholarship in the Westinghouse Science Talent Search. Following graduation from Harvard in 1972, Tsien attended Cambridge University in England under a Marshall Scholarship. There he learned organic chemistry --a subject he'd hated as an undergraduate-- and looked for a way to synthesize dyes for imaging neuronal activity, generating BAPTA based optical calcium indicator dyes. Following the completion of his postdoctoral training at Cambridge in 1982, Tsien accepted a faculty position at the University of California, Berkeley. There he and colleagues developed and improved numerous small molecule indicators, including indicators fura-2 and indo-1. In 1989, Tsien moved his laboratory to the University of California at San Diego, where he and his colleagues developed the enhanced mutant of GFP as a way to devise a cyclic AMP (cAMP) sensor for use in live cells. They initially engineered molecules to take advantage of the conformational change that occurs when cAMP binds to protein kinase A (PKA). By labeling one part of PKA with fluoroscein and another with a rhodamine, they hoped to detect Fluorescence Resonance Energy Transfer (FRET), which would occur when the two molecules were in close proximity. The initial experiments

McEwan, A.C.

1999-01-01

The 1998 annual meeting of the New Zealand Branch of the Australasian College of Physical Scientists and Engineers in Medicine was held at the Christchurch School of Medicine over 26-27 November 1998, and attracted a record number of around 45 registrations. The meeting serves a number of purposes but one of the primary ones is to bring together scientists in medicine from around the country to compare notes on practices and advances, particularly in radiotherapy and diagnostic radiology physics. Following the meeting format established over recent years, separate workshops were devoted to radiotherapy physics and developments in the regional centres represented, and to practical issues relating to medical physics in diagnostic radiology. The workshops were held in parallel with presentations of scientific papers covering a wide range of topics, but with about half relating to engineering applications in medicine. (author)

Summary of the ACRE inaugural meeting.

Bloomgarden, Zachary T

2009-01-01

The charter meeting of the Association of Clinical Researchers and Educators (ACRE) provided a powerful set of arguments against assertions that physician-industry collaboration is harmful and represents a "conflict of interest." Such collaboration has, in fact, improved medical care for patients, a case made overwhelmingly by patients and patient advocacy groups at the meeting. The contentions that physician-industry collaboration is problematic are not based on evidence. They depend on unjustified generalization from inevitable, sometimes egregious, but vanishingly uncommon adverse outcomes of industry-physician interaction without reference to how so much more commonly these interactions add value. Furthermore, the claim that physician-industry collaboration is unprofessional is refuted by rational scrutiny. Indeed, the term "conflict of interest" itself is vague, inviting subjectivity and deserving to be rejected. The unwarranted success of conflict of interest regulation has prevailed because of the failure of physicians, educators, and innovators, through apathy and intimidation, to pay attention to its fallacies and resist its dangers. It has arisen from activist ambitions and from misalignment between the purposes of medical practitioners, educators, and innovators and those of administrators in medical journals and in academic medical centers. The media and politicians have not appreciated these misalignments and have accepted conflict of interest arguments at face value. Regulation emanating from conflict of interest criticism is confusing, onerous, expensive, disrespectful, and damaging. Prohibitions against speaking about medical products inhibit physician and patient education concerning rapidly emerging and complex therapies. Input by physicians cognizant of compliance requirements into such presentations should be encouraged. Restrictions to the free flow of corporate support of academic health centers, professional societies, and patient

The objective of the present study was to conduct a short-term international course on translational physiology for medical students from Wright State University and the University of Iowa. The goals were to 1) provide students with an exposure to the academic, cultural, and medical environments in Brazil; 2) promote awareness of the global medical community; and 3) provide an academic course focused on translational physiology. An evaluation of the students was conducted to determine whether such a short-term course might be useful in the medical curriculum. The 2-wk course was held in the summer of 2005 at the University of São Paulo School of Medicine in Ribeirão Preto, Brazil, for 23 American students. The program included presentations of basic and clinical topics, meetings with medical students, and clinical presentations. The program finished with student attendance at a scientific meeting sponsored by the Brazilian Society of Hypertension. Student surveys evaluated issues related to perceived treatment, Brazilian medical school environment, culture and personal attributes, and career aspirations. The international Medical Sciences Translational Physiology course for medical students provided a brief, but intense, experience. It gave students a picture of the medical environment in Brazil and an appreciation for the differences and similarities in cultures. Most students reported that it was a positive experience that would be beneficial to their careers. In conclusion, a short-term international course provides an efficient means for medical students to experience aspects of global medical science.

Barr, Mary E.; Farish, Thomas J.

The recently released Supplemental Directive, NA-1 SD 1027, updates the radionuclide threshold values in DOE-STD-1027-92 CN1 to reflect the use of modern parameters for dose conversion factors and breathing rates. The directive also corrects several arithmetic errors within the original standard. The result is a roughly four-fold increase in the amount of weapons-grade nuclear material allowed within a designated radiological facility. Radiological laboratory space within the recently constructed Radiological Laboratory Office and Utility Building (RLUOB) is slated to house selected analytical chemistry support activities in addition to small-scale actinide R and D activities. RLUOB is within the same facility operations envelope as TA-55. Consolidation of analytical chemistry activities to RLUOB and PF-4 offers operational efficiency improvements relative to the current pre-CMRR plans of dividing these activities between RLUOB, PF-4, and CMR. RLUOB is considered a Radiological Facility under STD-1027 - 'Facilities that do not meet or exceed Category 3 threshold criteria but still possess some amount of radioactive material may be considered Radiological Facilities.' The supplemental directive essentially increases the allowable material-at-risk (MAR) within radiological facilities from 8.4 g to 38.6 g for 239 Pu. This increase in allowable MAR provides a unique opportunity to establish additional analytical chemistry support functions in RLUOB without negatively impacting either R and D activities or facility operations. Individual radiological facilities are tasked to determine MAR limits (up to the Category 3 thresholds) appropriate to their operational conditions. This study presents parameters that impact establishing MAR limits for RLUOB and an assessment of how various analytical chemistry support functions could operate within the established MAR limits.

Full Text Available Mobile devices emerge as the major players to ensure a favorable resource to connect, minimizing the limitation space-time constraints among people and enabling the use of emerging mobile learning (m-learning. The use of mobile devices in pedagogic praxis implies in a closer link between teachers in their initial development and their teacher educator in order to enable the incorporation of this mobile technology in undergraduate courses. This “approach” means the facilitation of meeting to discuss, reflect and talk about the incorporation of this technology in the teaching learning process. In this research, two professors had meetings to discuss and reflect about the employment of this mobile technology in the undergraduate course. One of them, a Chemistry teacher educator and the other is a computer and education teacher-research. The methodological approach is based on a qualitative method with some elements of action-research based on theoretical assumptions of the Activity Theory (ENGESTRÖM, 1999. Therefore, the study based on the debates over the use of mobile devices in the teaching of chemistry was developed as part of the undergraduate course in Chemistry at the Federal University of Rondonia. Among a set of activities, in which students and professors were present with their objects of specific activities, was presented the Activity system related to the construction of those activities. The analysis of SA from the perspective of the 5 principles of Activity Theory points out that the process of collaborative participation in the meetings, the implementation of activities with the students of the degree course and the preparation of scientific papers demonstrated the qualitative evolution of the chemistry teacher educator

Despite an abundance of online databases providing access to chemical data, there is increasing demand for high-quality, structure-curated, open data to meet the various needs of the environmental sciences and computational toxicology communities. The U.S. Environmental Protection Agency's (EPA) web-based CompTox Chemistry Dashboard is addressing these needs by integrating diverse types of relevant domain data through a cheminformatics layer, built upon a database of curated substances linked to chemical structures. These data include physicochemical, environmental fate and transport, exposure, usage, in vivo toxicity, and in vitro bioassay data, surfaced through an integration hub with link-outs to additional EPA data and public domain online resources. Batch searching allows for direct chemical identifier (ID) mapping and downloading of multiple data streams in several different formats. This facilitates fast access to available structure, property, toxicity, and bioassay data for collections of chemicals (hundreds to thousands at a time). Advanced search capabilities are available to support, for example, non-targeted analysis and identification of chemicals using mass spectrometry. The contents of the chemistry database, presently containing ~ 760,000 substances, are available as public domain data for download. The chemistry content underpinning the Dashboard has been aggregated over the past 15 years by both manual and auto-curation techniques within EPA's DSSTox project. DSSTox chemical content is subject to strict quality controls to enforce consistency among chemical substance-structure identifiers, as well as list curation review to ensure accurate linkages of DSSTox substances to chemical lists and associated data. The Dashboard, publicly launched in April 2016, has expanded considerably in content and user traffic over the past year. It is continuously evolving with the growth of DSSTox into high-interest or data-rich domains of interest to EPA, such

Tracking chemistry self-efficacy and achievement in a preparatory chemistry course

Science.gov (United States)

Garcia, Carmen Alicia

Self-efficacy is a person's own perception about performing a task with a certain level of proficiency (Bandura, 1986). An important affective aspect of learning chemistry is chemistry self-efficacy (CSE). Several researchers have found chemistry self-efficacy to be a fair predictor of achievement in chemistry. This study was done in a college preparatory chemistry class for science majors exploring chemistry self-efficacy and its change as it relates to achievement. A subscale of CAEQ, Chemistry Attitudes and Experiences Questionnaire (developed by Dalgety et al, 2003) as well as student interviews were used to determine student chemistry self-efficacy as it changed during the course. The questionnaire was given to the students five times during the semester: in the first class and the class before each the four tests taken through the semester. Twenty-six students, both men and women, of the four major races/ethnicities were interviewed three times during the semester and events that triggered changes in CSE were followed through the interviews. HLM (hierarchical linear modeling) was used to model the results of the CSE surveys. Among the findings, women who started at significantly lower CSE than men accomplished a significant gain by the end of the semester. Blacks' CSE trends through the semester were found to be significantly different from the rest of the ethnicities.

Recent developments in the chemistry of the transuranic elements are surveyed, with particular emphasis on computational contributions. Examples are drawn from molecular coordination and organometallic chemistry, and from the study of extended solid systems. The role of the metal valence orbitals in covalent bonding is a particular focus, especially the consequences of the stabilization of the 5f orbitals as the actinide series is traversed. The fledgling chemistry of transuranic elements in the +II oxidation state is highlighted. Throughout, the symbiotic interplay of experimental and computational studies is emphasized; the extraordinary challenges of experimental transuranic chemistry afford computational chemistry a particularly valuable role at the frontier of the periodic table. © 2018 Wiley-VCH Verlag GmbH & Co.

Nisbet, Gillian; Dunn, Stewart; Lincoln, Michelle

2015-01-01

This study explores the potential for workplace interprofessional learning, specifically the learning that occurs between health professionals as part of their attendance at their regular interprofessional team meetings. While most interprofessional learning research to date has focused on formal structured education programs, this study adds to our understanding of the complexities of the learning processes occurring between health professionals as part of everyday practice. Through observations of team meetings and semi-structured interviews, we found that the interprofessional team meeting provided a practical, time-efficient, and relevant means for interprofessional learning, resulting in perceived benefits to individuals, teams, and patients. The learning process, however, was influenced by members' conceptions of learning, participation within the meeting, and medical presence. This study provides a basis for further research to assist health professionals capitalize on informal learning opportunities within the interprofessional meeting.

Workshop report on large-scale matrix diagonalization methods in chemistry theory institute

Energy Technology Data Exchange (ETDEWEB)

Bischof, C.H.; Shepard, R.L.; Huss-Lederman, S. [eds.

1996-10-01

The Large-Scale Matrix Diagonalization Methods in Chemistry theory institute brought together 41 computational chemists and numerical analysts. The goal was to understand the needs of the computational chemistry community in problems that utilize matrix diagonalization techniques. This was accomplished by reviewing the current state of the art and looking toward future directions in matrix diagonalization techniques. This institute occurred about 20 years after a related meeting of similar size. During those 20 years the Davidson method continued to dominate the problem of finding a few extremal eigenvalues for many computational chemistry problems. Work on non-diagonally dominant and non-Hermitian problems as well as parallel computing has also brought new methods to bear. The changes and similarities in problems and methods over the past two decades offered an interesting viewpoint for the success in this area. One important area covered by the talks was overviews of the source and nature of the chemistry problems. The numerical analysts were uniformly grateful for the efforts to convey a better understanding of the problems and issues faced in computational chemistry. An important outcome was an understanding of the wide range of eigenproblems encountered in computational chemistry. The workshop covered problems involving self- consistent-field (SCF), configuration interaction (CI), intramolecular vibrational relaxation (IVR), and scattering problems. In atomic structure calculations using the Hartree-Fock method (SCF), the symmetric matrices can range from order hundreds to thousands. These matrices often include large clusters of eigenvalues which can be as much as 25% of the spectrum. However, if Cl methods are also used, the matrix size can be between 10{sup 4} and 10{sup 9} where only one or a few extremal eigenvalues and eigenvectors are needed. Working with very large matrices has lead to the development of

Implementing Family Meetings Into a Respiratory Care Unit: A Care and Communication Quality Improvement Project.

Science.gov (United States)

Loeslie, Vicki; Abcejo, Ma Sunnimpha; Anderson, Claudia; Leibenguth, Emily; Mielke, Cathy; Rabatin, Jeffrey

Substantial evidence in critical care literature identifies a lack of quality and quantity of communication between patients, families, and clinicians while in the intensive care unit. Barriers include time, multiple caregivers, communication skills, culture, language, stress, and optimal meeting space. For patients who are chronically critically ill, the need for a structured method of communication is paramount for discussion of goals of care. The objective of this quality improvement project was to identify barriers to communication, then develop, implement, and evaluate a process for semistructured family meetings in a 9-bed respiratory care unit. Using set dates and times, family meetings were offered to patients and families admitted to the respiratory care unit. Multiple avenues of communication were utilized to facilitate attendance. Utilizing evidence-based family meeting literature, a guide for family meetings was developed. Templates were developed for documentation of the family meeting in the electronic medical record. Multiple communication barriers were identified. Frequency of family meeting occurrence rose from 31% to 88%. Staff satisfaction with meeting frequency, meeting length, and discussion of congruent goals of care between patient/family and health care providers improved. Patient/family satisfaction with consistency of message between team members; understanding of medications, tests, and dismissal plan; and efficacy to address their concerns with the medical team improved. This quality improvement project was implemented to address the communication gap in the care of complex patients who require prolonged hospitalizations. By identifying this need, engaging stakeholders, and developing a family meeting plan to meet to address these needs, communication between all members of the patient's care team has improved.

Marcoule Institute for Separation Chemistry - 2009-2012 Scientific report

International Nuclear Information System (INIS)

Pellet-Rostaing, Stephane; Zemb, Thomas

2013-01-01

The mixed research unit 'Institute for Separation Chemistry' was created jointly by CEA, CNRS, University of Montpellier and Ecole Nationale Superieure de Chimie de Montpellier in March 2007. The building has been inaugurated in June 2009, with laboratories opened in the fall 2009 and has obtained authorisation to start experiments including a few grams of depleted uranium and natural thorium in January 2010. Last take-off was the theory group, who started in October 2009. Resources in Uranium are scarce, if only the 235 isotope is used and wastes related to nuclear energy production are potentially dangerous. The use of fast neutrons allows to multiply existing resources in national independence, but will be based on new separation processes, that can be modelled using predictive theory. Understanding and optimizing separation in the nuclear fuel cycle is the central aim of the 'Institute for Separation Chemistry' (ICSM). Enlarging this central goal to the needs for chemistry of recycling, for instance, strategic metals crucial for alternative energy, is the natural extension surfaces of needs and development of science, with a strong link for technology and implementation. This report gives an overview of the work published and submitted by ICSM since January 2009. The nine active research teams still work in the direction of the scientific open questions as defined and published by the French academy in 2007. The report is organized by scientific topics: each of the nine active research groups gathers a community of researchers and engineers from different expertises, who publish in various domains in the corresponding journals, and who participate at different international meetings. The research teams are organized as follows: 1 - Chemistry and Physical-chemistry of the Actinides; 2 - Ions at Active Interfaces; 3 - Ionic Separation from self-assembled Molecular systems; 4 - Sono-chemistry in Complex Fluids; 5 - Nano-materials for Energy and Recycling processes

'The medical' and 'health' in a critical medical humanities.

Atkinson, Sarah; Evans, Bethan; Woods, Angela; Kearns, Robin

2015-03-01

As befits an emerging field of enquiry, there is on-going discussion about the scope, role and future of the medical humanities. One relatively recent contribution to this debate proposes a differentiation of the field into two distinct terrains, 'medical humanities' and 'health humanities,' and calls for a supersession of the former by the latter. In this paper, we revisit the conceptual underpinnings for a distinction between 'the medical' and 'health' by looking at the history of an analogous debate between 'medical geography' and 'the geographies of health' that has, over the last few years, witnessed a re-blurring of the distinction. Highlighting the value of this debate within the social sciences for the future development of the medical humanities, we call for scholars to take seriously the challenges of critical and cultural theory, community-based arts and health, and the counter-cultural creative practices and strategies of activist movements in order to meet the new research challenges and fulfill the radical potential of a critical medical humanities.

Polymeric materials in medication

CERN Document Server

Carraher, Charles

1985-01-01

The art of using chemical agents for medication dates back into antiquity, although most of the earliest examples used plants, herbs, and other natural materials. The old Egyptian medical papyri, which date from before 1400 B. C. , contain dozens of examples of such medicinal plants and animal extracts. In the Old Testament of the Bible, we can find references to using oil to soften the skin and sores (Isaiah 1:6), the use of tree leaves for medicine (Ezekiel 47:12) and various medical balms (Jeremiah 8:22). Not all these recipes were effective in curing the ailments for which they were used and sometimes the treatment was worse than the disease. Nevertheless, the art of using chemical derived agents for medicines continued to develop and received great impetus during the present century with the rise of synthetic organic chemistry. One of the most vexing problems has always been to achieve specifici­ ty with the medications. While some medical agents do indeed possess a relatively high degree of specificity...

Mythbusting Medical Writing: Goodbye, Ghosts! Hello, Help!

Science.gov (United States)

Hamilton, Cindy W; Gertel, Art; Jacobs, Adam; Marchington, Jackie; Weaver, Shelley; Woolley, Karen

To meet ethical and scientific obligations, authors should submit timely, high-quality manuscripts. Authors, however, can encounter ethical (e.g., authorship designation) and practical (e.g., time and resource limitations) challenges during manuscript preparation. Could professional medical writers-not ghostwriters-help authors address these challenges? This essay summarizes evidence countering three myths that may have hindered authors from considering the use of professional medical writers. Authors with sufficient time, writing expertise, and reporting guideline knowledge may meet their obligations without writing assistance. Unfortunately, not all authors are in this position. Decisions about writing support should be based on evidence, not myths.

Chemistry, Poetry, and Artistic Illustration: An Interdisciplinary Approach to Teaching and Promoting Chemistry

Science.gov (United States)

Furlan, Ping Y.; Kitson, Herbert; Andes, Cynthia

2007-10-01

This article describes a successful interdisciplinary collaboration among chemistry, humanities and English faculty members, who utilized poetry and artistic illustration to help students learn, appreciate, and enjoy chemistry. Students taking general chemistry classes were introduced to poetry writing and museum-type poster preparation during one class period. They were then encouraged to use their imagination and creativity to brainstorm and write chemistry poems or humors on the concepts and principles covered in the chemistry classes and artistically illustrate their original work on posters. The project, 2 3 months in length, was perceived by students as effective at helping them learn chemistry and express their understanding in a fun, personal, and creative way. The instructors found students listened to the directives because many posters were witty, clever, and eye-catching. They showed fresh use of language and revealed a good understanding of chemistry. The top posters were created by a mix of A-, B-, and C-level students. The fine art work, coupled with poetry, helped chemistry come alive on campus, providing an aesthetic presentation of materials that engaged the general viewer.

Improvements of primary coolant shutdown chemistry and reactor coolant system cleanup

International Nuclear Information System (INIS)

Gaudard, G.; Gilles, B.; Mesnage, F.; Cattant, F.

2002-01-01

In the framework of a radiation exposure management program entitled >, EDF aims at decreasing the mass dosimetry of nuclear power plants workers. So, the annual dose per unit, which has improved from 2.44 m.Sv in 1991 to 1.08 in 2000, should target 0.8 mSv in the year 2005 term in order to meet the results of the best nuclear operators. One of the guidelines for irradiation source term reduction is the optimization of operation parameters, including reactor coolant system (RCS) chemistry in operation, RCS shutdown chemistry and RCS cleanup improvement. This paper presents the EDF strategy for the shutdown and start up RCS chemistry optimization. All the shutdown modes have been reviewed and for each of them, the chemical specifications will be fine tuned. A survey of some US PWRs shutdown practices has been conducted for an acid and reducing shutdown chemistry implementation test at one EDF unit. This survey shows that deviating from the EPRI recommended practice for acid and reducing shutdown chemistry is possible and that critical path impact can be minimized. The paper also presents some investigations about soluble and insoluble species behavior and characterization; the study focuses here on 110m Ag, 122 Sb, 124 Sb and iodine contamination. Concerning RCS cleanup improvement, the paper presents two studies. The first one highlights some limited design modifications that are either underway or planned, for an increased flow rate during the most critical periods of the shutdown. The second one focuses on the strategy EDF envisions for filters and resins selection criteria. Matching the study on contaminants behavior with the study of filters and resins selection criteria should allow improving the cleanup efficiency. (authors)

Usage and applications of Semantic Web techniques and technologies to support chemistry research.

Science.gov (United States)

Borkum, Mark I; Frey, Jeremy G

2014-01-01

The drug discovery process is now highly dependent on the management, curation and integration of large amounts of potentially useful data. Semantics are necessary in order to interpret the information and derive knowledge. Advances in recent years have mitigated concerns that the lack of robust, usable tools has inhibited the adoption of methodologies based on semantics. THIS PAPER PRESENTS THREE EXAMPLES OF HOW SEMANTIC WEB TECHNIQUES AND TECHNOLOGIES CAN BE USED IN ORDER TO SUPPORT CHEMISTRY RESEARCH: a controlled vocabulary for quantities, units and symbols in physical chemistry; a controlled vocabulary for the classification and labelling of chemical substances and mixtures; and, a database of chemical identifiers. This paper also presents a Web-based service that uses the datasets in order to assist with the completion of risk assessment forms, along with a discussion of the legal implications and value-proposition for the use of such a service. We have introduced the Semantic Web concepts, technologies, and methodologies that can be used to support chemistry research, and have demonstrated the application of those techniques in three areas very relevant to modern chemistry research, generating three new datasets that we offer as exemplars of an extensible portfolio of advanced data integration facilities. We have thereby established the importance of Semantic Web techniques and technologies for meeting Wild's fourth "grand challenge".

Over the past fifteen months, the Systems Chemistry Group of the Reactor Engineering Department has undertaken a comprehensive study of the Department's moderator chemistry program at Savannah River Site (SRS). An internal review was developed to formalize and document this program. Objectives were as outlined in a mission statement and action plan. In addition to the mission statement and action plan, nine separate task reports have been issued during the course of this study. Each of these task reports is included in this document as a chapter. This document is an organized compilation of the individual reports issued by the Systems Chemistry Group in assessment of SRS moderator chemistry to determine if there were significant gaps in the program as ft existed in October, 1989. While these reviews found no significant gaps in that mode of operation, or any items that adversely affected safety, items were identified that could be improved. Many of the items have already been dear with or are in the process of completion under this Moderator Chemistry Program and other Reactor Restart programs. A complete list of the items of improvement found under this assessment is found in Chapter 9, along with a proposed time table for correcting remaining items that can be improved for the chemistry program of SRS reactors. An additional external review of the moderator chemistry processes, recommendations, and responses to/from the Reactor Corrosion Mitigation Committee is included as Appendix to this compilation

We describe the history of the partnership between the chemistry departments at Rhodes University and the University of Bristol and provide an outline of the chemistry content of their outreach initiatives, the modes of delivery, the advantages to both departments and their students for involvement in various levels of outreach, the challenges they still face and additional opportunities that such work facilitated. The lecture demonstration ‘A Pollutant’s Tale’ was presented to thousands of learners all over the world, including learners at resource-deprived schools in South Africa. Challenges to extend outreach activities in South Africa include long travelling distances, as well as a lack of facilities (such as school halls and electricity at schools. Outreach activities not only impacted on the target audience of young learners, they also impacted upon the postgraduate and other chemistry students taking part in these initiatives. This collaboration strengthened both institutions and their outreach work and may also lead to chemistry research collaborations between the academics involved.

David J. Triggle: Medicinal chemistry, to pharmacology, calcium channels, and beyond.

Science.gov (United States)

Walker, Michael J A

2015-11-15

David Triggle's scientific career began as a chemist, went through medicinal chemistry into pharmacology, and finally on to somewhat more philosophical interests in later years. It was a career marked by many contributions to all of those aspects of science. Chief amongst his many contributions, in addition to those in medicinal chemistry, was his work on the drugs known as calcium ion channel blockers or (calcium antagonists). In the calcium ion channel field he was a particularly instrumental figure in sorting out the mechanisms, actions and roles of the class of calcium channel blockers, known chemical and pharmacologically as the dihydropyridines (DHPs) in particular, as well as other calcium blockers of diverse structures. During the course of a long career, and extensive journeys into medicinal chemistry and pharmacology, he published voluminously in terms of papers, reviews, conference proceedings and books. Notably, many of his papers often had limited authorship where, as senior author it reflected his deep involvement in all aspects of the reported work. His work always helped clarify the field while his incisive reviews, together with his role in coordinating and running scientific meetings, were a great help in clarifying and organizing various fields of study. He has had a long and illustrious career, and is wellknown in the world of biomedical science; his contributions are appreciated, and well recognized everywhere. The following article attempts to chart a path through his work and contributions to medicinal chemistry, pharmacology, science, academia and students. Copyright © 2015 Elsevier Inc.

Teaching Critical Thinking in Graduate Medical Education: Lessons Learned in Diagnostic Radiology.

Science.gov (United States)

Morrissey, Benjamin; Heilbrun, Marta E

2017-01-01

The 2014 Institute of Medicine report, Graduate Medical Education that Meets the Nation's Health Needs , challenged the current graduate medical training process and encouraged new opportunities to redefine the fundamental skills and abilities of the physician workforce. This workforce should be skilled in critically evaluating the current systems to improve care delivery and health. To meet these goals, current challenges, motivations, and educational models at the medical school and graduate medical education levels related to formal training in nonclinical aspects of medicine, especially critical thinking, are reviewed. Our diagnostic radiology training program is presented as a "case study" to frame the review.

Medication communication through documentation in medical wards: knowledge and power relations.

Science.gov (United States)

Liu, Wei; Manias, Elizabeth; Gerdtz, Marie

2014-09-01

Health professionals communicate with each other about medication information using different forms of documentation. This article explores knowledge and power relations surrounding medication information exchanged through documentation among nurses, doctors and pharmacists. Ethnographic fieldwork was conducted in 2010 in two medical wards of a metropolitan hospital in Australia. Data collection methods included participant observations, field interviews, video-recordings, document retrieval and video reflexive focus groups. A critical discourse analytic framework was used to guide data analysis. The written medication chart was the main means of communicating medication decisions from doctors to nurses as compared to verbal communication. Nurses positioned themselves as auditors of the medication chart and scrutinised medical prescribing to maintain the discourse of patient safety. Pharmacists utilised the discourse of scientific judgement to guide their decision-making on the necessity of verbal communication with nurses and doctors. Targeted interdisciplinary meetings involving nurses, doctors and pharmacists should be organised in ward settings to discuss the importance of having documented medication information conveyed verbally across different disciplines. Health professionals should be encouraged to proactively seek out each other to relay changes in medication regimens and treatment goals. © 2013 John Wiley & Sons Ltd.
