    GLANAM (Glaciated North Atlantic Margins) is an Initial Training Network (ITN) funded under the EU Marie Curie Programme. It comprises 10 research partners from Norway, UK and Denmark, including 7 University research teams, 1 industrial full partner and 2 industrial associate partners. The GLANAM network will employ and train 15 early career researchers (Fellows). The aim of GLANAM is to improve the career prospects and development of young researchers in both the public and private sector within the field of earth science, focusing on North Atlantic glaciated margins. The young scientists will perform multi-disciplinary research and receive training in geophysics, remote sensing, GIS, sedimentology, geomorphology, stratigraphy, geochemistry and numerical modeling through three interconnected work packages that collectively address knowledge gaps related to the large, glacial age, sedimentary depocentres on the North Atlantic margin. The 15 Fellows will work on projects that geographically extend from Ireland in the south to the High Arctic. Filling these gaps will not only result in major new insights regarding glacial age processes on continental margins in general, but will also provide paleoclimate information essential for understanding the role of marine-based ice sheets in the climate system and for the testing of climate models. GLANAM brings together leading European research groups working on glaciated margins in a coordinated and collaborative research and training project. Focusing on the North Atlantic margins, this coordinated approach will lead to a major advance in the understanding of glaciated margins more widely and will fundamentally strengthen European research and build capacity in this field.

    PARTNER (Particle Training Network for European Radiotherapy) is a project funded by the European Commission's Marie Curie-ITN funding scheme through the ENLIGHT Platform for 5.6 million Euro. PARTNER has brought together academic institutes, research centres and leading European companies, focusing in particular on a specialized radiotherapy (RT) called hadron therapy (HT), interchangeably referred to as particle therapy (PT). The ultimate goal of HT is to deliver more effective treatment to cancer patients leading to major improvement in the health of citizens. In Europe, several hundred million Euro have been invested, since the beginning of this century, in PT. In this decade, the use of HT is rapidly growing across Europe, and there is an urgent need for qualified researchers from a range of disciplines to work on its translational research. In response to this need, the European community of HT, and in particular 10 leading academic institutes, research centres, companies and small and medium-sized enterprises, joined together to form the PARTNER consortium. All partners have international reputations in the diverse but complementary fields associated with PT: clinical, radiobiological and technological. Thus the network incorporates a unique set of competencies, expertise, infrastructures and training possibilities. This paper describes the status and needs of PT research in Europe, the importance of and challenges associated with the creation of a training network, the objectives, the initial results, and the expected long-term benefits of the PARTNER initiative.

    The Marie Curie Initial Training Network »Isotopic Tools as Novel Sensors of Earth Surfaces Resources - IsoNose« is an alliance of eight international partners and five associated partners from science and industry. The project is coordinated at the Helmholtz Centre Potsdam GFZ German Research Centre for Geosciences and will run until February 2018. In the last 15 years advances in novel mass-spectrometric methods have opened opportunities to identify "isotopic fingerprints" of virtually all metals and to make use of the complete information contained in these fingerprints. The understanding developed with these new tools will ultimately guide the exploitation of Earth surface environments. However, progress in bringing these methods to end-users depends on a multi transfer of knowledge between (1) isotope Geochemistry and Microbiology, Environmental Sciences (2), Economic Geology and (3) instrument developers and users in the development of user-friendly and new mass spectrometric methods. IsoNose will focus on three major Earth surface resources: soil, water and metals. These resources are currently being exploited to an unprecedented extent and their efficient management is essential for future sustainable development. Novel stable isotope techniques will disclose the processes generating (e.g. weathering, mineral ore formation) and destroying (e.g. erosion, pollution) these resources. Within this field the following questions will be addressed and answered: - How do novel stable isotope signatures characterize weathering processes? - How do novel stable isotope signatures trace water transport? - How to use novel stable isotope as environmental tracers? - How to use novel stable isotope for detecting and exploring metal ores? - How to improve analytical capabilities and develop robust routine applications for novel stable isotopes? Starting from the central questions mentioned above the IsoNose activities are organized in five scientific work packages: 1

    The legend has only retained from Marie Curie (1867-1934) the image of a hard and brilliant worker, pioneer in the radioactivity domain, and who awarded twice the Nobel Price. Behind the scientist, there is a women, Marya Salomea Sklodowska, the 'Polish', who was considered during some time as an 'alien', an 'atheistic intellectual', an 'emancipated women'. When she died alone in July 1934, after an exhausting life of labour, her funeral led to no official ceremony or speech. This small book summarizes the biography of the most famous female scientist in the world

    Marie Curie is a women who changed the face of science for all time, not just because of her discovery of the radioactive element Radium and her work with it, but because of her incredible strides forward in a such a male dominated world as laboratory science at the turn of the 19th century. This is the Madame Curie many people know but here is a biography written by her daughter Eve that shows her human side, in a way that can only be viewed and admired from a family member describing her as a caring mother, devoted and passionate wife. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive.

Copernicus (previously known as GMES (Global Monitoring for Environment and Security) is a joint undertaking of the European Space Agency and the European Commission. It develops fully operational Earth Observation monitoring services for a community of end users from the public and private sector. The first services that are considered fully operational are the land monitoring and emergency monitoring core services. In GIONET, 14 early stage researchers are being trained at PhD level in understanding the complex physical processes that determine how electromagnetic radiation interacts with the atmosphere and the land surface ultimately form the signal received by a satellite. In order to achieve this, the researchers are based in industry and universities across Europe, as well as receiving the best technical training and scientific education. The training programme through supervised research focuses on 14 research topics. Each topic is carried out by an Early Stage Researcher based in one of the partner organisations and is expected to lead to a PhD degree. The 14 topics are grouped in 5 research themes: Forest monitoring Land cover and change Coastal zone and freshwater monitoring Geohazards and emergency response Climate adaptation and emergency response The methods developed and used in GIONET are as diverse as its research topics. GIONET has already held two summer schools; one at Friedrich Schiller University in Jena (Germany), on 'New operational radar satellite applications: Introduction to SAR, Interferometry and Polarimetry for Land Surface Mapping'. The 2nd summer school took place last September at the University of Leicester (UK )on 'Remote sensing of land cover and forest in GMES'. The next Summer School in September 2013

    The composition of the soil organic matter in soil developing under the influence of vegetation during the primary succession in the poor sandy area was investigated. The Curie-point pyrolysis method coupled with gas chromatographic separation and mass spectrometric identification of pyrolysates was applied during the investigation. A comparison of occurrence and diversity in composition of organic compounds in plant tissues and humus horizon of soils under the communities of coniferous forest series in the initial stages and phases was carried out. A large diversity of organic compounds under Algae-Cyanophyta communities, biological soil crusts and Polytrichum piliferum was noticed. A clear differentiation in the composition of the soil organic matter at different phases of succession under predominating communities with cryptogamous and vascular plants was observed. The analysis of organic compounds in plant tissues was found to facilitate the determination of origin of various groups of organic compounds in the soil. The results obtained from the Curie point pyrograms in the humus horizon (A) under grasses ( Corynephorus canescens, Koeleria glauca) differed from the pyrolysates obtained under Algae-Cyanophyta communities. The polysaccharide derivates are more frequent in the pyrolysis products under algae, grasses ( Corynephorus canescens, Koeleria glauca) and mosses than under Pinus sylvestris. In the beginning of the terminal stage of succession, lignin, phenols and aliphatic substances, prevailed over the polysaccharide derivates in the humus horizon.

    2007-04-01

    The year 2006 marked 100 years since the death of Pierre Curie. It is therefore appropriate that we remember his life and his work, which was cut short by his untimely death from an accident on the Pont Neuf, Paris, on April 19, 1906. He had already accomplished much during his life, both before the discovery of radium with Marie Curie, in work co-authored with his brother Jacques on piezoelectricity, and afterwards, when he published the results of several experimental studies with radium and radon. He came from a medical family, and his grandfather Pierre Curie was a famous homeopathic physician. He has, in print, unfairly been relegated to the background-his own scientific contributions having been overtaken by the fame of Marie Curie, probably because she outlived him by 28 years.

    The CUbesat Radio Interferometry Experiment (CURIE) is a proposed two-element radio interferometer, based on proven and developed digital radio receivers and designed to fit within a Cubesat platform. CURIE will launch as a 6U Cubesat and then separate into two 3U Cubesats once in orbit. CURIE measures radio waves from 0.1-19MHz, which must be measured from space, as those frequencies fall below the cutoff imposed by Earth's ionosphere. The principal science objective for CURIE is to use radio interferometry to study radio burst emissions from solar eruptive events such as flares and coronal mass ejections (CMEs) in the inner heliosphere, providing observations important for our understanding of the heliospheric space weather environment. The influence of space weather can be felt at Earth and other planets, as radiation levels increase and lead to auroral activity and geomagnetic effects. CURIE will be able to determine the location and size of radio burst source regions and then to track their movement outward from the Sun. In addition to the primary objective CURIE will measure the gradients of the local ionospheric density and electron temperature on the spatial scale of a few kilometers, as well as create an improved map of the radio sky at these unexplored frequencies. A space based radio interferometry observatory has long been envisioned, in orbit around the Earth or the Moon, or on the far side of the Moon. Beyond its important science objectives, CURIE will prove that the concept of a dedicated space-based interferometer can be realized by using relatively cheap Cubesats. CURIE will therefore not only provide new important science results but also serve as a pathfinder in the development of new space-based radio observation techniques for helio- and astro-physics.

    Full Text Available This experiment of innovative university education shows the interdisciplinary work carried out in the studies of the Bachelor of Science in Education at the University of Andorra. The study was developed within two subjects: Communication Technology (TAC and Cultural Heritage Education in Andorra. The main objective of this experiment is to foster the use of technological resources and digital materials, with the aim of drawing cultural heritage closer to the classroom. Based on a previous study of documentation and an analysis of online educational materials, the students have to design an e-book, which is understood to be digital material in the curricular field of cultural heritage. This digital material is a didactic proposal that focuses on the construction of knowledge by primary school students. During the elaboration of the materials the instructors introduce follow-up activities. The results of the experiment show that, from an interdisciplinary approach, and a problem-solving, learning-centered methodology, specific and transferable abilities in initial teacher training can be studied and evaluated.

    FeMnP{sub 0.75}Si{sub 0.25} experiences a first order para- to ferromagnetic transition at about 200 K. In common with some other alloy compositions crystallizing in the Fe{sub 2}P structure, the magnetic transition of the as prepared alloy occurs at a lower temperature than on subsequent cooling events. This virgin effect is found to be accompanied by a magnetostrictively induced irreversible structure change that persists on succeeding cooling heating cycles. These findings provide means to understand and control the thermal hysteresis of the (Fe{sub 1−x}Mn{sub x}){sub 2}P{sub 1−y}Si{sub y} alloy system which is a promising material class for use in magnetocaloric refrigerators. - Highlights: • FeMnP{sub 1−x}Si{sub x} exhibits a first order phase transition at the Curie temperature (T{sub c}). • The lattice parameters exhibit a discontinuous change at the transition. • The structure is permanently altered by the initial cooling through T{sub c}. • The transition temperature on cooling is enhanced by initial cooling. • Subsequent cooling/heating does not cause further changes of T{sub c}.

    The article aims at investigating the role of personality traits in relation to training initiation. Training initiation is conceptualized as a goal realization process, and explained using goal theories. There are three stages of the process analyzed: intention to undertake training, plan formulation, and actual training undertaking. Two studies tested the relationships between five personality traits, defined according to the five factor model, and the stages of the goal realization process. In Study 1, which explains training intention and training plans' formulation, 155 employees participated. In Study 2, which was time-lagged with two measurement points, and which explains intention, plans, and training actions undertaken, the data from 176 employees was collected at 3 month intervals. The results of these studies show that personality traits, mainly openness to experience, predict the training initiation process to some degree: intention, plans, and actual action initiation. The findings allow us to provide recommendations for practitioners responsible for human resource development. The assessment of openness to experience in employees helps predict their motivation to participate in training activities. To increase training motivation it is vital to strengthen intentions to undertake training, and to encourage training action planning.

    2017-01-01

    There will always be a requirement to reduce the size of initiation trains. However, as the size is reduced the performance characteristics can be compromised. A detailed science-based understanding of the processes (ignition and growth to detonation) which determine the performance characteristics is required to enable compact and robust initiation trains to be designed. To assess the use of numerical models in the design of initiation trains a modeling study has been undertaken, with the aim of understanding the initiation of TATB and HMX charges by a confined, surface mounted detonator. The effect of detonator diameter and detonator confinement on the formation of dead zones in the acceptor explosives has been studied. The size of dead zones can be reduced by increasing the diameter of the detonator and by increasing the impedance of the confinement. The implications for the design of initiation trains are discussed.

    A fulfillment of Curie's law in magnetic fluids provides an option of their thermometric applications to measure thermodynamic temperature. On the other hand, it was shown elsewhere that the initial magnetic susceptibility χ of magnetic fluids follows Curie-Weiss's law rather than Curie's law. To obtain its values, use was made of the formula χ = M/N0, where M is magnetization, and N0 is the external magnetic field strength without any specimen. This work deals with investigations of the dependence of magnetic susceptibility of magnetic fluid on temperature for the cases where its values are found via the following formulas: 1) χ = M/N0, and 2) χ = Mμ0/M, where M is the magnetic field induction inside the specimen. It is found that in the first case the temperature dependence of χ obeys Curie-Weiss's law while in the second case - Curie's law. The reason for this results from the fact that induction M acting on the particles of magnetic fluid is noticeably higher than that of the external field, M0.

    The EC FP6 Marie Curie Training Network "ModObs” http://www.modobs.windeng.net addresses the improvement of atmospheric boundary layer (ABL) models to investigate the interplay of processes at different temporal and spatial scales, and to explore the added value from new observation techniques. The overall goal is to bring young scientists to work ogether with experienced researchers in developing a better interaction amongst scientific communities of modelers and experimentalists, using a comprehensive approach to "Climate Change”, "Clean Energy assessment” and "Environmental Policies”, issues. This poster describes the work in progress of ten students, funded by the network, under the supervision of a team of scientists within atmospheric physics, engineering and satellite remote sensing and end-users such as companies in the private sector, all with the appropriate expertise to integrate the most advanced research methods and techniques in the following topics. MODELING: GLOBAL-TO-MESO SCALE: Analytical and process oriented numerical models will be used to study the interaction between the atmosphere and the ocean on a regional scale. Initial results indicate an interaction between the intensity of polar lows and the subsurface warm core often present in the Nordic Seas (11). The presence of waves, mainly swell, influence the MABL fluxes and turbulence structure. The regional and global wave effect on the atmosphere will be also studied and quantified (7) MESO-SCALE: Applicability of the planetary boundary layer (PBL) parametrizations in the meso-scale WRF model to marine atmospheric boundary layer (MABL) over the North Sea is investigated. The most suitable existing PBL parametrization will be additionally improved and used for downscaling North Sea past and future climates (2).

    Full Text Available This article begins by analysing the importance of socio-affective education at school, considering that it should be framed within ethics. It then analyses why it is important to train primary teachers in emotional education, advocating that it should be articulated around two basic standpoints: theoretical training and personal, experienced training, highlighting that the second one is crucial in order for primary teachers to emotionally educate their pupils. The article further focuses on the main socio-affective competences the primary teacher should have to face the challenges of education in such an unsettled and complex world as ours, positioning ourselves in favour of a socio-affective, experienced and active methodology. Finally, we provide an overview of emotional education in the Spanish school system and in primary teacher initial training curricula.

    A striking disparity exists across the globe, with essentially no large-scale longitudinal studies ongoing in regions that will be significantly affected by the oncoming non-communicable disease epidemic. The successful implementation of cohort studies in most low-resource research environments presents unique challenges that may be aided by coordinated training programs. Leaders of emerging cohort studies attending the First World Cohort Integration Workshop were surveyed about training priorities, unmet needs and potential cross-cohort solutions to these barriers through an electronic pre-workshop questionnaire and focus groups. Cohort studies representing India, Mexico, Nigeria, South Africa, Sweden, Tanzania and Uganda described similar training needs, including on-the-job training, data analysis software instruction, and database and bio-bank management. A lack of funding and protected time for training activities were commonly identified constraints. Proposed solutions include a collaborative cross-cohort teaching platform with web-based content and interactive teaching methods for a range of research personnel. An international network for research mentorship and idea exchange, and modifying the graduate thesis structure were also identified as key initiatives. Cross-cohort integrated educational initiatives will efficiently meet shared needs, catalyze the development of emerging cohorts, speed closure of the global disparity in cohort research, and may fortify scientific capacity development in low-resource settings.

    In 1898, the discovery of two new elements, polonium and radium, reawakened interest in the topic of uranic rays discovered 2 years before by H. Becquerel. Radioactivity, a name coined by Marie Curie, became a major research field for decades. The contrasting personalities of Pierre Curie, already a first-rank physicist, and of the young Marie Curie-Sklodowska as they undertook their common work are described. It is shown how a well-chosen quantitative method and a systematic approach combining physics and chemistry led to the discovery within less than 1 year. The special role of radium and the determination of its atomic weight by Marie Curie followed by her long-term program for accumulating pure radium salts are emphasized. The first woman with a full professorship at a French University, Marie Curie created and managed the Radium Institute.

  14. Factors influencing career choice after initial training in surgery.

    2012-02-01

    INTRODUCTION: Irish general surgery faces a recruitment crisis with only 87 of 145 (60%) basic surgical training (BST) places filled in 2009. We assessed basic surgical trainees to identify objective, and potentially modifiable, factors that influence ultimate recruitment into a general surgical career. METHODS: Candidates commencing BST training during a 5-year period between 2004 and 2008 were included in a quantitative study. In addition a total of 2,536 candidates, representing all those who commenced surgical training in Ireland since 1960 were identified through the Royal College of Surgeons in Ireland (RCSI) database and invited to complete an online survey. Statistical analysis was performed using SPSS version 15, with p < 0.05 considered significant. RESULTS: During the 5-year quantitative study period there were 381 BST trainees. Gender was a significant predictor of career choice with women more likely to ultimately choose a nonsurgical career after initial surgical training (p = 0.049). Passing surgical membership examinations (MRCS) also was predictive of remaining in surgery (p = 0.005). Training region was not a significant predictor of ultimate career choice. There were 418 survey respondents. The influence of role models was most commonly cited as influencing candidates in choosing to commence surgical training. Candidates who rated "academic opportunity" (p = 0.023) and "intellectual challenge" (p = 0.047) as factors that influenced their decision to commence surgical training were more likely to ultimately continue their careers in a surgical speciality. CONCLUSIONS: This study describes the career pathway of surgical trainees and confirms the importance of academic achievement in discriminating between candidates applying for surgical training schemes.

    Great names in science represent an inexhaustible source and richness of inspiration, satisfaction and consolation, a moving and victorious force. Throughout her exemplifying life, Maria Sklodowska remained modest but with a keen sense of humor, of an outstanding style, a mine of knowledge and experience, of innovative ideas and a rich inner life. Full of love, of passion to give and to share, of natural optimism, mixed with a light melancholy, so typical for sages. She vehemently defended the love of scientific research, of the spirit of adventure and entrepreneurship and fought for international culture, for the protection of personality and talent. Maria Sklodowska left her passion to science, her dedication to work including education and training of young people, her passionate adherence to her family, her belief in her friends, her pure and profound humanity and warmth! The paper should be a homage to her, an appreciation of her work over the years, but not less a correspondence, a conversation with her! On the other hand, the present solemn occasion resuscitates the personalities of Maria and Pierre Curie and their work, in particular of Maria Sklodowska in her own native land! In this manner, it truly contributes to her immortality!

    Pierre Curie, best known as a Nobel Laureate in Physics for his co-contributions to the field of radioactivity alongside research partner and wife Marie Curie, died suddenly in 1906 from a street accident in Paris. Tragically, his skull was crushed under the wheel of a horse-drawn carriage. This article attempts to honor the life and achievements of Pierre Curie, whose trailblazing work in radioactivity and piezoelectricity set into motion a wide range of technological developments that have culminated in the advent of numerous techniques used in neurological surgery today. These innovations include brachytherapy, Gamma Knife radiosurgery, focused ultrasound, and haptic feedback in robotic surgery.

    The Curie surface interpreted from magnetic data through spatial frequency domain techniques is used to provide information on the thermal structure of Borborema Province. The Borborema Province is part of the neoproterozoic collision of an orogenic system situated between the São Francisco-Congo and São Luís-West Africa cratons, which formed the Gondwana Supercontinent. The Curie surface of Borborema Province varies from 18 to 59 km, which reveals the complexity in the crustal composition of the study area. The thermal structure shows different crustal blocks separated by the main shear zones, which corroborates the evolution model of allochthonous terranes. The Curie surface signature for the west portion of Pernambuco Shear Zone may indicate processes of mantle serpentinization, once the Curie isotherm is deeper than Mohorovic discontinuity. In this region, the amplitude of Bouguer anomaly decreases, which corroborates long wavelength anomaly observed in the magnetic anomaly. We interpreted this pattern as evidence of the Brasiliano-Pan-Africano's subduction/collision event. Earthquakes in the region are concentrated mainly in shallow Curie surface regions (less resistant crust) and in transition zones between warm and cold blocks. We calculated the horizontal gradient of the Curie depth to emphasize the signature of contact between the thermal blocks. These regions mark possible crustal discontinuities, and have high correlation with orogenic gold occurrence in the study area.

    Full Text Available The local development should complete a group of basic principles, such as: the design for training and the tools information adapted to the particularity of each territory. This training facilitates, also, the articulation of the stocks deployed by the local leaders, and it increases the administration of the knowledge and the transfer of technologies, processes in those that the nexuses are enlarged between the structures and the population, and where the participation of different present actors is potentialized in the territory. During the year 2010 the Ministry of Economy and Planning begins to offer the possibility to finance projects for the local development, nevertheless these initiatives should be accompanied by a rigorous study of feasibility of the investments. The University of Sancti Spíritus, committed in this zeal, designs the Diplomate of Administration of Projects for Local Initiatives, which offers theoretical tools and it develops practical abilities in the different actors of the local development that facilitate the realization of these studies. The exercise of this graduate's culmination consists on the defence of the study of feasibility of those projects that each municipality identifies as priority for its development.

  5. Pioneers of nuclear medicine, Madame Curie.

    Grammaticos, Philip C

    Among those who have made important discoveries in the field of radioactivity and thus helped in the development of nuclear medicine as an identical entity are: Heinrich Hertz who in 1886 demonstrated the existence of radiowaves. In 1895 Wilhelm Röntgen discovered the X-rays. In 1896 H. Becquerel described the phenomenon of radioactivity. He showed that a radioactive uranium salt was emitting radioactivity which passing through a metal foil darkened a photographic plate. An analogous experiment performed by S.Thomson in London was announced to the president of the Royal Society of London before the time H.Becquerel announced his discovery but Thomson never claimed priority for his discovery. Muarie Sklodowska Curie (1867-1934) was undoubtedly the most important person to attribute to the discovery of radioactivity. In 1898 she discovered radium as a natural radioactive element. This is how she describes the hard time she had, working with her husband Pierre Curie (1859-1906) for the discovery of radium and polonium: "During the first year we did not go to the theater or to a concert or visited friends. I miss my relatives, my father and my daughter that I see every morning and only for a little while. But I do not complain...". In presenting her discovery of radium, Madame Curie said: " ...in the hands of a criminal, radium is very dangerous. So we must often ask ourselves: will humanity earn or lose from this discovery? I, myself belong to those who believe the former...". The notebooks that Madame Curie had when she was working with radium and other radioactive elements like polonium, thorium and uranium are now kept in Paris. They are contaminated with radioactive materials having very long half-lives and for this reason anyone who wishes to have access to these notes should sign that he takes full responsibility. There are some more interesting points in Madame Curie's life which may not be widely known like: Although her full name is Maria Sklodowska-Curie

    Mass-casualty incidents (MCIs) present a unique challenge with regards to triage as patient volume often outweighs the number of available Emergency Medical Services (EMS) providers. A possible strategy to optimize existing triage systems includes the use of other first responder groups, namely fire and police, to decrease the triage time during MCIs, allowing for more rapid initiation of life-saving treatment and prioritization of patient transport. Hypothesis First-year primary care paramedic (PCP), fire, and police trainees can apply with similar accuracy an internationally recognized MCI triage tool, Sort, Assess, Life-saving interventions, Treatment/transport (SALT), immediately following a brief training session, and again three months later. All students enrolled in the PCP, fire, and police foundation programs at two community colleges were invited to participate in a 30-minute didactic session on SALT. Immediately following this session, a 17-item, paper-based test was administered to assess the students' ability to understand and apply SALT. Three months later, the same test was given to assess knowledge retention. Of the 464 trainees who completed the initial test, 364 (78.4%) completed the three month follow-up test. Initial test scores were higher (Pfirst responder trainees, PCPs were able to apply the SALT triage tool with the most accuracy, followed by fire, then police. Over-triage was the most frequent error, while critical errors were rare.

    Full Text Available The initial training that future educators receive must be prepared for the education of adults, which includes knowing the characteristics of the group and overcoming the stereotypes towards them. However, not always achieved. The purpose of this communication is to approximate the stereotypes that early educators (elementary school teachers and social educators have about adult education. To this end, 110 students of teachers in the specialty of Primary Education and 151 of social education responded to a Likert scale questionnaire in which eight items related to stereotypes towards adult education. From the results obtained, the most outstanding stereotypes are present in issues related to the management of new technologies and the learning capacity of this group.

  8. Women who Worked with Marie Curie.

    2015-06-01

    Marie Curie directed a research laboratory for 28 years. Between 1906 and 1934, forty five women worked under her guidance. Some were, and are, well-known in their own countries as their first woman full professor such as Ellen Gleditsch or Margaret von Wrangel, but for twenty eight of them, who were often French, nothing has ever been written. The strong presence of women in Marie Curie's laboratory has often been highlighted and has been considered as an exception, and the result of deliberate choice. Of course, these women did not choose this workplace by accident. They knew its director was a woman, a laureate of one, and after 1911, two Nobel Prizes, who was leading a well-equipped laboratory with an important radioactive source. But how did Marie Curie selected her collaborators among the many applications she received? Was her choice influenced by gender? A prosopographical research based on genealogical researches and new sources explains this presence contextually and sheds light on several questions : where did these women come from, what were their social and geographic origins, did they occupy any specific cultural or technical area inside Curie's lab, what future did they have after the laboratory? Through their lives, we can question the existence, or not, of a one profile of the female researcher in scientific areas in France.

    2011-01-01

    Marie Curie, née Maria Sklodowska, was born on November 7, 1867 in Warsaw (Poland). She suffered from leukaemia and died on June 4, 1934. She was buried with full honours at Pantheon. Marie Curie and her husband Pierre Curie discovered the radioactive elements Polonium (84Po210), Thorium (90Th232) and Radium (88Ra226). Marie Curie introduced the term radioactivity into science. She was the first woman who got Ph.D. in France, the first woman professor at Sorbonne, Paris and Medical Academy. Of all the women who have ever won the Nobel Prize, Marie Curie was the only who received it twice. During World War I Marie Curie designed a mobile x-ray room "radiologic car". Marie Curie had an x-ray machine installed into a car and demonstrated how to use its dynamo for electric power production necessary for the x-ray machine to work. She had 20 cars with moving radiological lab made and trained 150 people to work on them. She brought something radically new into military medicine--mobile x-ray diagnostics. With the discovery of radioactive elements a new medical branch, radiotherapy, was developed.

    Standard business training programs aim to boost the incomes of the millions of self-employed business owners in developing countries by teaching basic financial and marketing practices, yet the impacts of such programs are mixed. We tested whether a psychology-based personal initiative training approach, which teaches a proactive mindset and focuses on entrepreneurial behaviors, could have more success. A randomized controlled trial in Togo assigned microenterprise owners to a control group (n = 500), a leading business training program (n = 500), or a personal initiative training program (n = 500). Four follow-up surveys tracked outcomes for firms over 2 years and showed that personal initiative training increased firm profits by 30%, compared with a statistically insignificant 11% for traditional training. The training is cost-effective, paying for itself within 1 year. Copyright © 2017 The Authors, some rights reserved; exclusive licensee American Association for the Advancement of Science.

    2008-07-01

    In Paris in 1894, two young physicists fall in love: Marie Sklodowska and Pierre Curie. They get married and make great contributions to science, research radioactivity and discover new chemical elements. The marriage of Marie and Pierre Curie is quite modern: They work together as equals, share their thoughts and pursue their plans together as partners. They share an absolute interest in science, a love of nature, and a sceptic attitude towards the sophisticated society of the Belle Epoque. They are together 24 hours a day with hardly ever any disagreement. Whenever one of them is ill - which is quite often because of the high level of radioactivity in their laboratory -, the other will nurse him or her. After only twelve years of mutual love, Pierre Curie dies. Marie raises their two daughters on her own and continues her research. In 1911, she will be the first scientist that ever gets a second Nobel Prize. (orig.) [German] Im Paris des Jahres 1894 verlieben sich zwei junge Physiker: Marie Sklodowska und Pierre Curie. Sie heiraten und leisten gemeinsam Grosses fuer die Wissenschaft, erforschen die Radioaktivitaet und entdecken neue chemische Elemente. Zusammen erhalten sie den Nobelpreis. Marie und Pierre Curie fuehren eine Ehe, die ihrer Zeit weit voraus ist: Sie arbeiten gleichberechtigt miteinander, teilen ihre Gedanken und verfolgen ihre Plaene gemeinsam. Beiden eigen ist die absolute wissenschaftliche Neugier, die Liebe zur Natur und die Skepsis gegenueber der mondaenen Gesellschaft der Belle Epoque. Fast jeden Tag sind sie rund um die Uhr zusammen, dabei gibt es selten Spannungen. Wenn einer von beiden gesundheitliche Probleme hat - und das haben sie wegen der radioaktiven Belastung im Labor oft - ist der andere fuer ihn da und pflegt ihn. Nach nur zwoelf gemeinsamen Jahren der Liebe und Arbeit stirbt Pierre Curie. Marie zieht ihre beiden Toechter alleine gross und fuehrt die Forschungen weiter. 1911 erhaelt sie als erster Mensch zum zweiten Mal den

    2012-08-01

    In 2009, the nuclear industry employed approximately 120,000 people. Nearly 38 percent of the nuclear industry force will be eligible to retire within the next five years. To maintain the current work force, the industry will need to hire approximately 25,000 more workers by 2015. Given that the current radiochemistry workforce is approaching the age for retirement and that a limited number of US universities provide experience with radiochemistry, the United States is faced with a growing demand for the education and training of scientists in the radiochemistry arena. Furthermore, it is critical that the US maintains global leadership in the next generation of safe nuclear energy technology from both a national security and environmental perspective. This will require a robust program that focuses entirely on educating and training the next generation of radiochemists in subjects such as 1- radioanalysis of actinides and radioelements not only in the environment but in medium pertinent to the back end of the nuclear fuel cycle, 2- speciation of radionuclides, 3- detection methods, 4- safeguards etc… Therefore, the National Analytical Management Program (NAMP) has organized a subcommittee focusing on training and education in radiochemistry. Through the efforts of this subcommittee, NAMP has established collaborative associations to foster the exchange of scientific and technical information with professors in radiochemistry programs at different universities. This paper will present our accomplishments and the development of a curriculum for an intermediate radiochemistry course in cooperation with the EPA. These short (2-hour) webinar presentations on specific radiochemistry topics have been developed and will be presented. The webinars are recorded and will become a library or collection of information for on-line access from the NAMP website.

    The International Society of Biometeorology (ISB) has covered significant breadth and depth addressing fundamental and applied societal and environmental challenges in the last 60 years. Biometeorology is an interdisciplinary science connecting living organisms to their environment, but there is very little understanding of the existence and placement of this discipline within formal educational systems and institutions. It is thus difficult to project the ability of members of the biometeorological community—especially the biometeorologists of the future—to help solve global challenges. In this paper, we ask: At present, how we are training people to understand and think about biometeorology? We also ask: What are the current tools and opportunities in which biometeorologists might address future challenges? Finally, we connect these two questions by asking: What type of new training and skill development is needed to better educate "biometeorologists of the future" to more effectively address the future challenges? To answer these questions, we provide quantitative and qualitative evidence from an educationally focused workshop attended by new professionals in biometeorology. We identify four common themes (thermal comfort and exposures, agricultural productivity, air quality, and urbanization) that biometeorologists are currently studying and that we expect to be important in the future based on their alignment with the United Nations Sustainable Development Goals. Review of recent literature within each of these thematic areas highlights a wide array of skill sets and perspectives that biometeorologists are already using. Current and new professionals within the ISB have noted highly varying and largely improvised educational pathways into the field. While variability and improvisation may be assets in promoting flexibility, adaptation, and interdisciplinarity, the lack of formal training in biometeorology raises concerns about the extent to which

    2015-08-01

    Recent dramatic events have brought to the forefront the debate on how to protect, safeguard and document Cultural Heritage in conflict areas. Heritage places have become battlefields, sources of illicit trafficking and even deliberate targets of destruction because of the politicisation to further conflict ideologies as well as misinterpretation of the values they represent. Is it possible to protect Cultural Heritage under such circumstances? If yes, when is the right time to intervene and who can help in this task? How can documentation and training assist? The International Course on First Aid to Cultural Heritage in Times of Crisis promoted by ICCROM (The International Centre for the Study of the Preservation and Restoration of Cultural Property) in collaboration with various partners focuses specifically on ways to help in such difficult and stressful situations. This paper explores the methodological approach and highlights the special circumstances that surround rapid documentation and preliminary condition assessment in conflict areas, and in cases of complex emergencies such as an earthquake striking a conflict area. The paper identifies international actors that might play a special and crucial role in the first steps of such a situation and recognizes the need for training activities to strengthen capacities for disaster response to cultural heritage at national and regional levels.

    Marie Curie was a remarkable woman whose discoveries broke new ground in physics and chemistry and also opened the door for advances in engineering, biology, and medicine. She broke new ground for women in science: she was, for example, the first woman to receive a doctor of science degree in France, the first woman to win Nobel Prize, the first woman to lecture at the Sorbonne, the first person to win two Nobel Prizes, and the first Nobel Laureate whose child also won a Nobel Prize. Her life offers insights into the changing role of women in science and academia over the past century. It also offers examples of many ways in which scientists can, and should, work to improve the educational programs and career opportunities available to those who follow in their footsteps.

    For many reasons the year 1898 was unusual for Maria Skłodowska-Curie and her husband. After defining the subject of the doctoral thesis and choosing Henri Becqerel as thesis supervisor, Maria started intensive experimental work. In the allotted room called storeroom, in conditions that were far too inadequate, they managed to put up a unique measuring equipment composed of instruments whose originator was Pierre Curie. In the ionization chamber and in the piezoelectric quartz charges formed, whose mutual neutralization was shown by the quadrant electrometer. Ionization current, which was measured quantitatively, was proportional to the radiation of the sample. Studying many elements, their compounds and minerals enabled Maria to state that uranium is not the only element endowed with the power of radiation; the second one turned out to be thorium. Anomaly detected in the radiation of uranium minerals made it possible for Maria to draw an extremely important conclusion: radioactive uranium and thorium are not the only elements endowed with such an attribute. Pitchblende, which was studied by the Curie couple, had to contain also other radioactive substances. Gustave Bémont also participated in the chemical analysis of the uranium ore and it is worth reminding that he was involved in the discovery of polonium and uranium. The phenomenon of radioactivity couldn't have been explained if it was not for the sources of strong radioactivity. Those sources undoubtedly could have been the discovered elements but their scanty content in the uranium ore made their isolation very difficult and laborious. Access to industrial remains after procession of pitchblende from Jachymov (Sankt Joachimstahl), obtained owing to the mediation of Eduard Suess, provided the source of this raw material. From it, in a shack also called le hangar, the Curie couple isolated the first samples of the radium salt. This element, later extracted by discoverers on a grand scale and handed over in a

    Ferromagnetic resonance properties of F1/f/F2/AF multilayers, where weakly ferromagnetic spacer f is sandwiched between strongly ferromagnetic layers F1 and F2, with F1 being magnetically soft and F2-magnetically hard due to exchange pinning to antiferromagnetic layer AF, are investigated. Spacer-mediated exchange coupling is shown to strongly affect the resonance fields of both F1 and F2 layers. Our theoretical calculations as well as measurements show that the key magnetic parameters of the spacer, which govern the ferromagnetic resonance in F1/f/F2/AF, are the magnetic exchange length (Λ), effective saturation magnetization at T  =  0 (m0) and effective Curie temperature (T(C)(eff)). The values of these key parameters are deduced from the experimental data for multilayers with f  =  Ni(x)Cu(100-x), for the key ranges in the Ni-concentration (x = 54 ÷ 70 at. %) and spacer thickness (d = 3 ÷ 6 nm). The results obtained provide a deeper insight into thermally-controlled spin precession and switching in magnetic nanostructures, with potential applications in spin-based oscillators and memory devices.

    Available cognitive remediation interventions have a significant but relatively small to moderate impact on episodic memory in schizophrenia. The present study aimed to evaluate the efficacy and feasibility of a brief novel episodic memory training targeting the self-initiation of semantic encoding strategies. To select patients with such deficits, 28 participants with schizophrenia performed our Semantic Encoding Memory Task (SEMT) that provides a measure of self-initiated semantic encoding strategies. This task identified a deficit in 13 participants who were then offered two 60-minute training sessions one week apart. After the training, patients performed an alternate version of the SEMT. The CVLT-II (a standardised measure of semantic encoding strategies) and the BVMT-R (a control spatial memory task) were used to quantify memory pre- and post-training. After the training, participants were significantly better at self-initiating semantic encoding strategies in the SEMT (p = .004) and in the CVLT-II (p = .002). No significant differences were found in the BVMT-R. The current study demonstrates that a brief and specific training in memory strategies can help patients to improve a deficient memory process in schizophrenia. Future studies will need to test this intervention further using a randomised controlled trial, and to explore its functional impact.

    The robotic surgical platform is being utilized by a growing number of hospitals across the country, including academic medical centers. Training programs are tasked with teaching their residents how to utilize this technology. To this end, we have developed and implemented a robotic surgical curriculum, and share our initial experience here. Our curriculum was implemented for all General Surgical residents for the academic year 2014-2015. The curriculum consisted of online training, readings, bedside training, console simulation, participating in ten cases as bedside first assistant, and operating at the console. 20 surgical residents were included. Residents were provided the curriculum and notified the department upon completion. Bedside assistance and operative console training were completed in the operating room through a mix of biliary, foregut, and colorectal cases. During the fiscal years of 2014 and 2015, there were 164 and 263 robot-assisted surgeries performed within the General Surgery Department, respectively. All 20 residents completed the online and bedside instruction portions of the curriculum. Of the 20 residents trained, 13/20 (65 %) sat at the Surgeon console during at least one case. Utilizing this curriculum, we have trained and incorporated residents into robot-assisted cases in an efficient manner. A successful curriculum must be based on didactic learning, reading, bedside training, simulation, and training in the operating room. Each program must examine their caseload and resident class to ensure proper exposure to this platform.

    Full Text Available Inclusive education is hard to implement in secondary schools. Probably, one of the determining factors lies in teachers' initial  training that determines their attitude, identity and professional practice. This research analyses the initial teacher education programmes for Secondary Education, Higher Secondary Education, called bachillerato in Spain, and Vocational and Artistic training in the five best valued Spanish universities in the education field, according to the ranking I-UGR, after the European convergence process in the European Higher Education Area. The study analyses the national regulations that govern this training. A quantitative study was conducted to examine the number of credits dedicated to inclusive education and also a review of the contents of these subjects was carried out. The study concludes that this initial teacher training provides sufficient theoretical basis regarding the conceptualization of inclusive education and the skills to deal with the tutorship and academic and professional orientation. However, important limitations in training prevent future teachers from identifying students’ and context’s special educational needs, and the attention to diversity through different methods and curriculum adaptations.

    Type 2 diabetes can be a problem for captive chimpanzees. Accurate blood glucose (BG) readings are necessary to monitor and treat this disease. Thus, obtaining voluntary samples from primates through positive reinforcement training (PRT) is critical. The current study assessed the voluntary participation of 123 chimpanzees in BG sampling and investigated factors that may contribute to individual success. All subjects participate in regular PRT sessions as part of a comprehensive behavioral management program. Basic steps involved in obtaining BG values include: voluntarily presenting a finger/toe; allowing digit disinfection; holding for the lancet device; and allowing blood collection onto a glucometer test strip for analysis. We recorded the level of participation (none, partial, or complete) when each chimpanzee was first asked to perform the testing procedure. Nearly 30% of subjects allowed the entire procedure in one session, without any prior specific training for the target behavior. Factors that affected this initial successful BG testing included sex, personality (chimpanzees rated higher on the factor "openness" were more likely to participate with BG testing), and past training performance for "present-for-injection" (chimpanzees that presented for their most recent anesthetic injection were more likely to participate). Neither age, rearing history, time since most recent anesthetic event nor social group size significantly affected initial training success. These results have important implications for captive management and training program success, underlining individual differences in training aptitude and the need for developing individual management plans in order to provide optimal care and treatment for diabetic chimpanzees in captivity.

    The initiation of pointe training for dance students should be determined after careful evaluation of a number of factors. These include: the dance student's stage of physical development; the quality of her (or his) trunk, abdominal and pelvic control ("core" stability); the alignment of her legs (hip-knee-ankle-foot); the strength and flexibility of her feet and ankles; and the duration and frequency of her dance training. For students who meet the requirements related to all of these factors, began ballet training at age eight or later, and who are taking ballet class at least twice per week, pointe work should be initiated in the fourth year of training. Students with poor core stability or hypermobility of the feet and ankles may require additional strengthening to allow them to safely begin pointe training. For those who are only taking ballet classes once per week, or who are not truly pre-professional, pointe training should be discouraged. No student with insufficient ankle and foot plantar flexion range of motion or with poor lower extremity alignment should be allowed to do pointe work.

    Biographies of scientists occupy a liminal space, highly popular with general readers but questioned in academia. Nonetheless, in recent years, historians of science have not only embraced the genre with more enthusiasm and less guilt, they have also turned to the metabiography in order to renew the study and story of scientists' roles. This essay focuses on Marie Curie, the world's most famous female scientist, in order to unpack some of the theoretical and methodological claims of the science biography, and especially to address the sexing mechanisms at play in the construction of the biographical subject. Pierre Curie (1923), Marie's biography of her husband Pierre, paid tribute to her dead husband and collaborator, but also allowed Curie a legitimate outlet to construct her own persona and legacy. Categories such as personhood, person, and persona are not only central to the biography genre but also are essential to the sense of self and self-fashioning of scientists. Looking at how Marie Curie negotiated these categories in Pierre Curie not only gives new insight into Curie's self-fashioning strategies but may also shed some light on the more general analytical lacunae of the science biography.

  14. Referrals to the Marie Curie nursing service in North Yorkshire.

    District and Marie Curie nurses participated in a small-scale study to describe referrals to a Marie Curie service in one English health district over a 3-month period. The number of new patients referred was small; they were geographically clustered and had widely differing life expectancies. Anecdotal reports of difficulties with the 'Nurselink' referral system were not confirmed, and in situations where the system was in operation, Marie Curie nurses were more likely to speak directly to the referring nurse. The most frequently cited reason for referral was general nursing needs; however, Marie Curie nurses felt that they were most often involved to provide family support. These findings suggest that there may not be a shared understanding of the Marie Curie nurse's role, and that equity in community palliative nursing care merits examination. Defining and publicizing the role of the Marie Curie nurse, providing guidance for referrals and prioritizing communication between professionals are proposed not only to enhance the service locally but to ensure that the service is available to all. This article illustrates the value of research to identify ways to improve service delivery.

    There is always a requirement to reduce the size of initiation trains. However, as the size is reduced the performance characteristics may be compromised. To enable compact and robust initiation trains to be designed requires a detailed science-based understanding of the processes (for example, growth to detonation) which determine the performance characteristics. A numerical modelling study has been performed to understand the designs of initiation trains comprising flyer plate detonator, booster charge and an IHE main charge. The effect of the flyer plate diameter on the distance required to establish uniformly diverging detonation waves in HMX and TATB based booster charges has been studied. Numerical simulations have also examined the effect of the relative sizes of the booster and IHE main charge on the distance required for a stable detonation front to be established in the main charge for both HMX and TATB based booster charges. The implications of the numerical simulations are discussed in terms of the design of initiation trains for IHE main charge systems.

    Marie Curie was awarded the Nobel Prize in 1903 and in 1911. Also her daughter, Irene Joliot-Curie, received a Nobel Prize for science in 1935. In this book an overview is given of the academic world at that time: limited access to universities for women, the carriers of both women in physics and their pioneering research and discoveries, the refusal of Marie Curie by the French Academy of Sciences, the awarding of the Nobel Prize and the assignment of Irene Joliot-Curie as the first female minister in France, the impact of the two World Wars, their married and private lives and the constant smear campaign of the press against both women. The lives and works of both women are hold against the light of the present position of women in physical sciences. [Dutch] In 1903, precies honderd jaar geleden, ontving Marie Curie als eerste vrouw de Nobelprijs voor de Wetenschap, gevolgd door een tweede Nobelprijs in 1911. Ook haar dochter Irene Joliot-Curie kreeg de Nobelprijs voor de wetenschap in 1935. Marie and Irene Curie schetst een breed beeld van de academische wereld waarin beide vrouwen zich bewogen: de beperkte toegang van vrouwen tot de universiteit, hun carrisres in de natuurkunde en baanbrekende ontdekkingen, de afwijzing van Marie door de Franse Academie des Sciences, de toekenning van de Nobelprijs en de benoeming van Irene als eerste vrouwelijke minister in Frankrijk, de invloed van de twee Wereldoorlogen, hun huwelijks- en priveleven en de niet aflatende hetze van de pers tegen beiden. In de door mannen gedomineerde wereld van de natuurwetenschappen liep de uitzonderingspositie van beide vrouwen als rode draad door hun curieuze levens. Het leven en werk van de Curies wordt geactualiseerd door deze tegen het licht te houden van de huidige positie van vrouwen in de natuurwetenschappen. Het bereiken van de top van de wetenschap door vrouwen blijkt nog steeds uitzonderlijk.

In difference to previous pessimistic conclusions in which this type of intervention was assessed as weak and stressed the persistence of preconceived notions of the candidates based on personal experiences from earlier schooling, more recent studies, in the constructivistic spirit of the change of cognition of the students - future teachers is considered more widely, not only as a complete change of the contents of their convictions, i.e. a sudden turn in their attitudes on the group level, but also as a smaller or bigger level of idiosyncratic reconstruction of the existing pedagogic convictions which happens because of acquiring new information and experiences that can reflect significantly on their future work in classroom. The aim of our research was to explore, by reviewing scientific and professional literature, the effects of the initial education and training of foreign language teachers, and focusing on different aspects of the preparation for the teacher's profession (theoretical lecturing and practical training, to find out in which ways various programs can influence the cognition of foreign language teachers and to consider pedagogic implications that these information might have for the organization of initial education and training of students.

    Full Text Available Abstract Background The will to eat is a decision associated with conditioned responses and with unconditioned body sensations that reflect changes in metabolic biomarkers. Here, we investigate whether this decision can be delayed until blood glucose is allowed to fall to low levels, when presumably feeding behavior is mostly unconditioned. Following such an eating pattern might avoid some of the metabolic risk factors that are associated with high glycemia. Results In this 7-week study, patients were trained to estimate their blood glucose at meal times by associating feelings of hunger with glycemic levels determined by standard blood glucose monitors and to eat only when glycemia was Conclusion Subjects could be trained to accurately estimate their blood glucose and to recognize their sensations of initial hunger at low glucose concentrations. These results suggest that it is possible to make a behavioral distinction between unconditioned and conditioned hunger, and to achieve a cognitive will to eat by training.

    Full Text Available We present a study that aims to know how the students of the Master’s Degree in Secondary Teacher Training begin to build their Teaching Professional Identity, as well as what the main implications of this identification process are, in order to improve their training. Through an open questionnaire, a total of 355 opinions of students from the University of Córdoba have been analysed. The conclusions obtained highlight: a the students show a professional identity that is significantly less developed than in other professional groups; b it is important to develop activities to reflect on the nature of the teaching profession by improving the identification of students with the characteristics of the teaching profession. Some of the implications from this research point to the need to take into consideration the results obtained when designing the process of initial training of future secondary teachers. Particularly, it would be necessary to include the issue of Teaching Professional Identity more specifically in the curriculum of the new model of initial training. This, moreover, should be linked to the pedagogical knowledge of the contents and the acquisition of real teaching skills according to the development of the educational curriculum for each subject.

    A resolution of the 63rd Assembly of the United Nations proclaimed the year 2011 as the International Year of Chemistry. The coordinators of the event are UNESCO and the International Union of Pure and Applied Chemistry (IUPAC). The patroness of this event is Marie Curie, nee Sklodowska. Among women scientists, she was the first recipient of the Novel Prize, and among all scientists, she is the only one who has received this award in different scientific fields (in 1903 in the field of physics with Pierre Curie and Henri Becquerel, in 1911 in the field of chemistry). Considering the former Polish nationality of Marie Curie, the year 2011 has been proposed by the Polish Parliament as her year, using the name Maria Sklodowska Curie, under which she is known in Poland. Celebrating the International Year of Chemistry is a good opportunity to remember the importance of the work of Maria Sklodowska Curie for the emergence and development of many fields of science. This article is an attempt to present a view of science, as taught through modern applications of the radiation chemistry of polymetric materials and radiation sterilization. Although the real development of both ''cold'' sterilization and polymer technology occurred in the 1950's long after the death of Marie Curie Sklodowska, the original ideas go back to ther work performed in the 1920s. Sometimes, and that is the present case, a single scientist creates a new field, in spite of the fact that at the time of discovery there are no applications. The parallel development of other branches of science and technology helps the application of the original idea. (orig.)

  11. Size and shape effects on Curie temperature of ferromagnetic nanoparticles

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    A simplified model was developed to describe the Curie temperature suppression of ferromagnetic nanoparticles. Based on a size and shape dependent model of cohesive energy, the critical temperature variations of ferromagnetic nanoparticles were deduced. It is predicted that the Curie temperature of nanoparticles depends on both size and shape conditions, among which the temperature suppression is strongly influenced by the particle size and the shape effect is comparably minor. The calculation values for freestanding nanoparticles are in good agreement with other theoretical model and the experimental results. The model is also potential for predictions for the nanoparticles embedded in different substrates.

    The U.S. Geological Survey's Land Change Monitoring, Assessment, and Projection (LCMAP) initiative is a new end-to-end capability to continuously track and characterize changes in land cover, use, and condition to better support research and applications relevant to resource management and environmental change. Among the LCMAP product suite are annual land cover maps that will be available to the public. This paper describes an approach to optimize the selection of training and auxiliary data for deriving the thematic land cover maps based on all available clear observations from Landsats 4-8. Training data were selected from map products of the U.S. Geological Survey's Land Cover Trends project. The Random Forest classifier was applied for different classification scenarios based on the Continuous Change Detection and Classification (CCDC) algorithm. We found that extracting training data proportionally to the occurrence of land cover classes was superior to an equal distribution of training data per class, and suggest using a total of 20,000 training pixels to classify an area about the size of a Landsat scene. The problem of unbalanced training data was alleviated by extracting a minimum of 600 training pixels and a maximum of 8000 training pixels per class. We additionally explored removing outliers contained within the training data based on their spectral and spatial criteria, but observed no significant improvement in classification results. We also tested the importance of different types of auxiliary data that were available for the conterminous United States, including: (a) five variables used by the National Land Cover Database, (b) three variables from the cloud screening "Function of mask" (Fmask) statistics, and (c) two variables from the change detection results of CCDC. We found that auxiliary variables such as a Digital Elevation Model and its derivatives (aspect, position index, and slope), potential wetland index, water probability, snow

    The aim of this study was to determine whether formal clinical research training is of value in the initiation of a successful career as a clinical investigator. We conducted a retrospective review of the career choices of all 25 fellows who entered the Academic Clinical Research Track at Brigham and Women's Hospital since its inception in 1995 and examined the impact of formal clinical research training during their fellowship on their career choice. The primary measure of a successful career as a clinical investigator was the obtainment of external funding for clinical research within 3 years of completion of fellowship. Thirteen of the 25 fellows (52%) received a Master of Public Health (MPH) degree at the Harvard School of Public Health during their fellowship. Ten of these 13 fellows (77%) obtained external funding for clinical research within 3 years of completion of their fellowship. None of the 5 fellows who had already obtained an MPH degree prior to their fellowship and none of the 7 fellows who completed a 7-week summer Program in Clinical Effectiveness but did not complete an MPH degree attempted to receive external funding for clinical research within 3 years of completion of their fellowship. We conclude that formal clinical research training culminating in an MPH degree was extremely valuable in the initiation of a successful career as a clinical investigator.

    The aim of our study was to evaluate the responses to an exercise programme with respect to initial fitness in subjects with cystic fibrosis (CF). 72 subjects (42 female) aged 10-43 yrs (forced expiratory volume in 1 s of 62.0 ± 26.7% predicted) were included. Participants were divided into three groups based on peak oxygen uptake expressed as % predicted. Subjects participated in a multifaceted rehabilitation programme, including five-times-a-week exercise training, for 6 weeks. Exercise and ventilatory capacity were determined by a maximal incremental cycling test. Oxygen uptake, workload and peak cardiac frequency at peak and submaximal workload were used as parameters for exercise capacity and responsiveness to training. Lung function values were significantly different between groups (p fitness level. Responsiveness to training showed differences between groups (p fitness level. The improvements in exercise parameters in CF at peak and VAT depended on the fitness level at baseline, independent of lung function. These improvements seen after training were comparable with those seen in healthy subjects, suggesting that responsiveness to exercise is similar in CF and in healthy untrained persons.

    The present meta-analysis evaluated the effectiveness of bystander education programs for preventing sexual assault in college communities. Undergraduates trained in bystander education for sexual assault were expected to report more favorable attitudes, behavioral proclivities, and actual behaviors relative to untrained controls. Data from 12 studies of college students (N = 2,926) were used to calculate 32 effect sizes. Results suggested moderate effects of bystander education on both bystander efficacy and intentions to help others at risk. Smaller but significant effects were observed regarding self-reported bystander helping behaviors, (lower) rape-supportive attitudes, and (lower) rape proclivity, but not perpetration. These results provide initial support for the effectiveness of in-person bystander education training. Nonetheless, future longitudinal research evaluating behavioral outcomes and sexual assault incidence is needed.

  17. Initiation of bladder voiding with epidural stimulation in paralyzed, step trained rats.

    Directory of Open Access Journals (Sweden)

    Parag N Gad

    Full Text Available The inability to control timely bladder emptying is one of the most serious challenges among the several functional deficits that occur after a complete spinal cord injury. Having demonstrated that electrodes placed epidurally on the dorsum of the spinal cord can be used in animals and humans to recover postural and locomotor function after complete paralysis, we hypothesized that a similar approach could be used to recover bladder function after paralysis. Also knowing that posture and locomotion can be initiated immediately with a specific frequency-dependent stimulation pattern and that with repeated stimulation-training sessions these functions can improve even further, we reasoned that the same two strategies could be used to regain bladder function. Recent evidence suggests that rats with severe paralysis can be rehabilitated with a multisystem neuroprosthetic training regime that counteracts the development of neurogenic bladder dysfunction. No data regarding the acute effects of locomotion on bladder function, however, were reported. In this study we show that enabling of locomotor-related spinal neuronal circuits by epidural stimulation also influences neural networks controlling bladder function and can play a vital role in recovering bladder function after complete paralysis. We have identified specific spinal cord stimulation parameters that initiate bladder emptying within seconds of the initiation of epidural stimulation. The clinical implications of these results are substantial in that this strategy could have a major impact in improving the quality of life and longevity of patients while simultaneously dramatically reducing ongoing health maintenance after a spinal cord injury.

    Stereotactic body radiation therapy is a rapidly growing advanced treatment technique that delivers high radiation dose with great precision. The implementation of stereotactic body radiation therapy should be associated with a specific initial training and continuing professional education for radiation oncologists and medical physicists. The creation of a French stereotactic body radiation therapy group gathering radiation oncologists (SFRO and AFCOR) and medical physicists (SFPM) is mandatory in order to create dedicated national guidelines, prospective databases and to promote clinical trials in this field.

A cross-sectional analyses compared 2008-2010 mailed surveys of CPTI graduates 5 years after residency graduation with comparably aged respondents in a 2010 mailed national American Academy of Pediatrics survey of US pediatricians (CPTI: n = 234, response = 56.0%; national sample: n = 243; response = 59.9%). Respondents reported demographic characteristics, practice characteristics (setting, time spent in general pediatrics), involvement in community child health activities in past 12 months, use of ≥1 strategies to influence community child health (eg, educate legislators), and being moderately/very versus not at all/minimally skilled in 6 such activities (eg, identify community needs). χ(2) statistics assessed differences between groups; logistic regression modeled the independent association of CPTI with community involvement adjusting for personal and practice characteristics and perspectives regarding involvement. Compared with the national sample, more CPTI graduates reported involvement in community pediatrics (43.6% vs 31.1%, P .05). Differences in involvement remained in adjusted analyses with greater involvement by CPTI graduates (adjusted odds ratio 2.4, 95% confidence interval 1.5-3.7). Five years after residency, compared with their peers, more CPTI graduates report having skills and greater community pediatrics involvement. Enhanced residency training in community pediatrics may lead to a more engaged pediatrician workforce. Copyright © 2014 by the American Academy of Pediatrics.

    Full Text Available Background: Health advocacy is a critical aspect of the competent physician's role. It is identified as a core competency by several national physician regulatory organizations, yet few formal training programs exist. We developed an initiative to teach medical students health advocacy skills. Methods: At Political Action Day, students from Alberta medical schools lobbied the provincial government. A day of training seminars preceded Political Action Day that focused on teaching health advocacy and communication strategies. The following day, medical students met with elected representatives at the Legislative Assembly. An entry and exit survey was administered to students. Results: On October 26-27th, 2008, 40 students met with 38/83 (46% elected representatives including the Minister of Health and Wellness. Feedback from students and politicians suggests the event was effective in teaching advocacy skills. This initiative inspired students to be politically active in the future. Conclusions: Political Action Day helps fulfill the health advocacy competency objectives, and requires minimal curriculum time and resources for integration. It is an effective tool to begin teaching advocacy, and should be further expanded and replicated at other Canadian medical schools.

    Maria Skłodowska Curie left us a great legacy. Her discovery of polonium and radium was incomparably greater than the mere discovery of new elements. Its significance lay in the discovery of a new form of matter, namely radioactive one, but also in her unveiling of the internal property of its atoms. Subsequently emitted radiation went on to play the role of a "natural accelerator" for both scientific research and in medical radiotherapy. It was thanks to these discoveries that the field of nuclear physics arose just a few decades later. As importantly the work of Maria Curie Skłodowska during the Great War demonstrated how important pure scientific discovery can be for society and its welfare.

    The ESR signal of lithium intercalated MCMB can be well simulated by combination of a Lorentz curve and a Gauss curve. The ESR intensity of the Lorentz component is essentially independent of temperature while the Gauss component shows a linear change with the reciprocal of temperature, indicative of Pauli spin and Curie spin, respectively. The former is probably associated with the ordered (graphitized) structures while the latter with the disordered structures in the sample.

    Marie Sklodowska-Curie, an extraordinary woman, a Polish scientist who lived and worked in France, led to the development of nuclear energy and the treatment of cancer. She was the laureate of two Nobel Prizes, the first woman in Europe who obtained the degree of Doctor of Science and opened the way for women to enter fields which had been previously reserved for men only. As a result of her determination and her love of freedom, she has become an icon for many female scientists active in radiation sciences. They are successors of Maria Curie and without the results of their work, improvement in radiation oncology will not be possible. Many of them shared some elements of Maria Curie's biography, like high ethical and moral standards, passionate dedication to work, strong family values, and scientific collaboration with their husbands. The significance of Tikvah Alper, Alma Howard, Shirley Hornsey, Juliana Denekamp, Helen Evans, Eleanor Blakely, Elizabeth L. Travis, Fiona Stewart, Andree Dutreix, Catharine West, Peggy Olive, Ingela Turesson, Penny Jeggo, Irena Szumiel, Eleonor Blakely, Sara Rockwell and Carmel Mothersill contribution to radiation oncology is presented. All the above mentioned ladies made significant contribution to the development of radiotherapy (RT) and more efficient cancer treatment. Due to their studies, new schedules of RT and new types of ionizing radiation have been applied, lowering the incidence of normal tissue toxicity. Their achievements herald a future of personalized medicine.

The initial stage of training is of particular importance due to incorporation into a complex new system of educational environment. The aim of the work - to study the characteristics of adaptation process in the first-year students. Functional state of students’ organism was studied by visual-motor response, function of attention, speed, of information processing, tepping-test. This cross-sectional study included 179 first-year medical students. Students with a history of hearing or visual disorder, smoking, alcoholism, cardiovascular and respiratory disease and on medication which affects cognitive performance were excluded from the study. Participation in the test was voluntary and informed written consent was taken from each participant. Academic performance was analyzed. Pearson correlation has been used to find the significance of relationship between the speed of thought processes, function of attention, factor of motometria, volume of visual memory and academic performance. Adaptation of students to training is based on the functional system of the body. Expressed correlation between the speed of thought processes (r=0,63, р<0,01, function of attention (r=0,47, р<0,05, ratio of motometry (r=0,45, р<0,05, volume of visual memory (r=0,43, р<0,05 and academic performance was established.

    Full Text Available The article shows the results of a research study, which was carried out in a regional public state university from southern Chile, in order to find out knowledge and use of ICT that Initial Teacher Training Program students have. Specifically, the study intends to look for answers related to computer literacy, type of access and use of ICT and, at the same time, promotes reflection on how the curriculum should prepare future teachers in order to guarantee learning and competencies in this area. Using a transversal descriptive quantitative methodology, a validated questionnaire (Cronbach Alpha 0.89 was answered by a sample of 150 students belonging to cohort 2009. We conclude that teacher training students have an easy access to ICT resources and, therefore, they are native subjects who show a high computer literacy degree. However, they do not use specific programs related to education nor do they know how they can take advantage of that ICT knowledge in the teaching learning process within the classroom in their future professional career.

    At the national level, the process which integrates nurse education curriculum to university studies, as well as the creation of a program of nursing and paramedical research in the hospital are contributing to the promoting of these professions inside the scientific community. The research introduction is now a teaching unit, which emphasizes professionalizing and training through research and opens the question of the visibility and the development in France, of a discipline in nursing. To establish an inventory of the implementation of the teaching units concerning introduction to research. A survey was sent to 305 educational institutions through an online questionnaire. it emerges some obstacles to the development of research including a low expertise in paradigms and research methods, the need for training of trainers, a low use of research articles and a gap between the teachings of the program and teachings made. The results highlight the difficulties in the implementation of the research initiation and the heterogeneity in the implementation of the teaching unit that could affect the process of professionalization of the student.

    Within the UK, there is growing recognition that individuals will need to take increased responsibility for managing their own health for there to be improvements in population health. The current evidence base on self care interventions reflects an interest in enhancing self care knowledge, skills and behaviour in relation to the management of long-term conditions. In contrast, this paper reports on a community-based self care initiative that was designed to promote self care approaches in the general population. The principal component was a self care skills training course delivered to groups of lay people in community and workplace settings. Self Care for People was piloted in three primary care trusts and a process evaluation was undertaken. The aim of this paper is to examine the feasibility, relevance and acceptability of the initiative. Qualitative interviews were conducted with a sample of stakeholders involved in implementation including coordinators, trainers and key informants from organisations hosting the course. In total 40 interviews and two focus groups were conducted from 2006 to 2008 and the data were analysed thematically. The evaluation found that implementation was relatively straightforward with few major barriers reported. Recruitment to the self care skills training course took place in both workplace and community group settings, including in organisations supporting socially excluded groups. The course was seen to provide a valuable space for contemplation on personal health, however, participation could raise sensitive issues that needed to be dealt with by skilled facilitators. Motivations for involvement differed markedly in host organisations and different strategies for marketing were adopted. The paper concludes by suggesting that while Self Care for People was both feasible and relevant to different stakeholder groups, there needs to be flexibility in responding to the needs of participants in different settings.

We developed and examined the implementation of an online training for the Building Recovery by Improving Goals, Habits, and Thoughts (BRIGHT) intervention-a manualized, sixteen-session group depression treatment for individuals with substance use disorders (SUDs). We explored the feasibility of replacing in-person BRIGHT training with a self-paced, online training. A highly partnered and iterative process was followed to translate the written BRIGHT manual and associated didactic training materials into a media rich, interactive, and detailed (12-16 h) online training. Subsequently, 8 volunteer counselors across 7 Veterans' Affairs SUD programs completed the training. Semi-structured interviews focused on the counselors' experiences and their plans for implementing BRIGHT groups. A template approach, using a mixture of deductive and inductive coding, was used for data analyses. The most important barrier to completing training was a lack of protected time. Most counselors were not afforded protected time and reported a sometimes frustrating and fragmented training experience. Many used personal time at work and at home to complete the work. Facilitators to completing the training included positive reactions/attitudes towards the training modules, supervisor support, counselor dedication, and strong beliefs supporting providing services for depression. Many counselors were also concerned about the feasibility of fitting 16 group sessions (2h each) into their program's clinical schedule, but many had devised potential solutions or "work-arounds" to accommodate or approximate the recommended treatment course (e.g., using lunch times, reducing

    Effect of pressure on the Curie temperature TC of the Mn-rich Heusler alloys Mn2RuSn and Mn2PdSn has been investigated by measuring the temperature dependence of initial permeability at various pressures up to 10 kbar. It was found that the Curie temperatures of Mn2RuSn and Mn2PdSn decrease with increasing pressure. The pressure derivatives of TC were estimated to be -0.59 K/kbar for Mn2RuSn and -0.80 K/kbar for Mn2PdSn. On the basis of the experimental results, the relationship between the magnetic transition temperature and the Mn-Mn distance is discussed.

    End goal of translational medicine is to combine disciplines and expertise to eventually promote improvement of the global healthcare system by delivering effective therapies to individuals and society. Well-trained experts of the translational medicine process endowed with profound knowledge of biomedical technology, ethical and clinical issues, as well as leadership and teamwork abilities are essential for the effective development of tangible therapeutic products for patients. In this article we focus on education and, in particular, we discuss how programs providing training on the broad spectrum of the translational medicine continuum have still a limited degree of diffusion and do not provide professional support and mentorship in the long-term, resulting in the lack of well established professionals of translational medicine (TMPs) in the scientific community. Here, we describe the Marie Skłodowska-Curie Actions program ITN-EUtrain (EUropean Translational tRaining for Autoimmunity & Immune manipulation Network) where training on the Translational Medicine machinery was integrated with education on professional and personal skills, mentoring, and a long-lasting network of TMPs.

    Full Text Available In this study, we investigate the effectiveness of perceptual training, administered to Argentinean learners, in the perception and production of word-initial voiceless stops in English. 24 participants were divided into 3 groups: (i Group 1, which participated in 3 training sessions; (ii Group 2, which, besides performing the same training tasks, was explicitly informed about the target item; (iii Group 3 (control. All participants took part in a pre-test, a post-test and a delayed post-test. In all these phases, they participated in a consonant identification task and took part in a reading exercise. Our results show a significant increase of both experimental groups in identification. As for production, Group 2 exhibited a significant increase in /p/ and /t/ after training. These results are indicative of the effectiveness of perceptual training tasks in helping learners focus on Voice Onset Time.

  8. A BIC Based Initial Training Set Selection Algorithm for Active Learning and Its Application in Audio Detection

    Directory of Open Access Journals (Sweden)

    2013-06-01

    Full Text Available To construct a classification system or a detection system, large amounts of labeled samples are needed. However, manual labeling is dull and time consuming, so researchers have proposed the active learning technology. The initial training set selection is the first step of an active learning process, but currently there have been few studies on it. Most active learning algorithms adopt random sampling or algorithms like sampling by clustering (SBC to select the initial training samples. But these two kinds of method would lose their effectiveness in detecting events of small probability. Because sometimes they could not select or select too few samples of the small probability events. To solve this problem, this paper proposes a BIC based initial training set selection algorithm. The BIC based algorithm performs clustering on the whole training set first. Then uses BIC to judge the status of clusters. Finally, it adopts different selection strategies for clusters of different status. Experimental results on two real data sets show that, compared to random sampling and SBC, the proposed BIC based initial training set selection algorithm can efficiently solve the detection problem of small probability events. In the mean time, it has obvious advantages in detecting events of non-small probability.

    To determine the efficacy of an educational curriculum designed for orthopedic surgery postgraduate year 1 (PGY-1) interns to improve initial Orthopedic In-Training Examination (OITE) performance. A retrospective cohort study was performed that evaluated the PGY-1 intern OITE performance of one residency training program (n = 55) during 7-year periods before (1996-2002) and after structured curriculum implementation (2003-2009). Linear regression analysis revealed insignificant changes in median PGY-1 intern OITE percentile rank during the precurriculum period (R = 0.08, P = 0.53). Postcurriculum period comparisons revealed significantly improving PGY-1 intern OITE percentile rank (R = 0.46, P = 0.048). Pre- and postcurriculum median US Medical Licensing Examination (USMLE) Step I scores did not display statistically significant differences (218.2 ± 6.6 vs 229.1 ± 13.8, Mann-Whitney U test, z = -1.5, P = 0.10). Spearman rho correlations revealed a moderate relation (r = 0.61) between postcurriculum PGY-1 intern OITE percentile rank and USMLE Step I score, but not during the precurriculum period. A moderate relation (r = 0.50) also was observed between postcurriculum USMLE Step I score and average OITE percentile rank during the 5-year residency program, but not during the precurriculum period. PGY-1 intern OITE percentile rank improved significantly with the addition of a specially designed educational curriculum. The stronger USMLE Step I score and PGY-1 intern OITE percentile rank relation observed during the postcurriculum period suggests that interns who participated in the educational curriculum were better prepared to translate general medical and patient care knowledge into orthopedic surgery knowledge.

    The participatory, action-oriented training program in occupational safety and health named POSITIVE (Participation-Oriented Safety Improvements by Trade Union InitiatiVE) was established in Pakistan and extended to other countries in Asia. The steps taken in the development of the POSITIVE program included collecting local good examples in safety and health, developing an action-checklist, testing a participatory training program, and conducting follow-up activities to examine local achievements. Training manuals were compiled to provide workers with the practical, easy-to-understand information on safety and health improvements and on the positive roles of trade unions. Trade union trainers trained in the methodology conducted serial POSITIVE training workshops in Pakistan and then in Bangladesh, Mongolia, Nepal, the Philippines and Thailand and recently in China. These workshops resulted in many low-cost improvements at the workplace level. These improvements were carried out in the technical areas of materials handling, workstations, machine safety, physical environment, and welfare facilities. The trade union networks have been vital in reaching an increasing number of grass-root workplaces and in expanding the program to other countries. This included the visits to Mongolia and Thailand of Pakistani trade union trainers to demonstrate the POSITIVE training. The participatory training tools used in the POSITIVE program such as the action checklist and group discussion methods were commonly applied in different local situations. Participatory approaches adopted in the POSITIVE program have proven useful for providing practical problem-solving measures based on the local trade union initiative.

    2016-01-01

    This paper proposes a conditional Curie-Weiss model as a model for opinion formation in a society polarized along two opinions, say opinions 1 and 2. The model comes with interaction strength $\\beta>0$ and bais $h$. Here the population in question is divided into three main groups, namely: Group one consisting of individuals who have decided on opinion 1. Let the proportion of this group be given by $s$. Group two consisting of individauls who have chosen opinion 2. Let $r$ be their proportion. Group three consisting of individuals who are yet to decide and they will decide based on their environmental conditions. Let $1-s-r$ be the proportion of this group. We show that the specific magnetization of the associated conditional Curie-Weiss model has a first order phase transition (discontinuous jump in specific magnetization) at $\\beta^*=\\left(1-s-r\\right)^{-1}$. It is also shown that not all the discontinuous jumps in magnetization will result in phase change. We point out how an extention of this model could...

    Hyperthermia induced by the heating of magnetic particles (MPs) in alternating magnetic field receives a considerable attention in cancer therapy. An interesting development in the studies dedicated to magnetically based hyperthermia is the possibility to control the temperature using MPs with selective magnetic absorption properties. This paper analyzes the temperature field determined by the heating of MPs having low Curie temperature (a FeCrNbB particulate system) injected within a malignant tissue, subjected to an ac magnetic field. The temperature evolution within healthy and tumor tissues was analyzed by finite element method simulations in a thermo-fluid model. The cooling effect produced by blood flowing in blood vessels was considered. This effect is intensified at the increase of blood velocity. The FeCrNbB particles, having the Curie temperature close to the therapeutic range, transfer the heat more homogeneous in the tumor keeping the temperature within the therapeutic range in whole tumor volume. Having the possibility to automatically control the temperature within a tumor, these particle type opens new research horizons in the magnetic hyperthermia.

    Full Text Available Purpose: It has become crucial to translate scientific findings and to find ways by which to mobilize local resources to improve the quality and accessibility of cancer care in developing countries. This study seeks to provide insight into challenge through examining differences in clinician documentation of patients with cancer treated at a Brazilian Public University Hospital. Methods: ASCO Quality Oncology Practice Initiative (QOPI measures were used to examine the care provided in the departments of breast, colorectal, lymphoma, gynecology, and lung cancers. For this study, data from a representative sample of patients receiving chemotherapy in the previous month were extracted and quality of cancer care indicators examined. Results: Certain elements of medical care were consistently and appropriately documented, including cancer diagnosis and stage, chemotherapy planning, administration, and summary. In general, considering the specific cancer management measures, patients received recommended care in accordance with recognized guidelines. Despite this, a number of important gaps in care were identified, including the assessment and treatment of pain, documentation of chemotherapy intention, symptom and toxicity management, patients’ psychosocial status, and provision of a treatment summary at care completion. Conclusion: These findings are encouraging in terms of adherence to core treatment guidelines in cancer care in Brazil. However, results suggest important opportunities for improving care across a number of domains, many of which represent a challenge throughout both developing and developed countries. This study may also provide preliminary guidance for enhancing educational and training programs for professionals and students alike, to implement high-quality, comprehensive cancer care.

    The magnetic properties of epitaxial Fe films on GaAs in the range of the first few monolayers have been the subject of a considerable number of investigations in recent years. The absence of magnetic signatures at room temperature has been attributed to the existence of a magnetic 'dead' layer as well as superparamagnetism. By examining the temperature dependence of the magnetic linear dichroism of the Fe core level photoelectrons, we found a ferromagnetic regime with a Curie temperature, T {sub c} substantially lower than room temperature, e.g., a T {sub c} of about 240 K for thin films of a nominal thickness of 0.9 nm. The values of Curie temperature were sensitive to the initial GaAs substrate conditions and the thickness of the Fe over-layer with a layer of thickness of 1.25 nm showing a T {sub c} above room temperature. The data suggest that the thin Fe films on GaAs(0 0 1) may have ferromagnetic character at an earlier stage of growth than previously expected, although a weaker exchange interaction in the films leads to a substantial reduction in Curie temperature.

    Despite the importance of community health workers (CHWs) in strategies to reduce health disparities and the call to enhance their roles in research, little information exists on how to prepare CHWs involved in community-academic initiatives (CAIs). Therefore, the New York University Prevention Research Center piloted a CAI-CHW training program. We applied a core competency framework to an existing CHW curriculum and bolstered the curriculum to include research-specific sessions. We employed diverse training methods, guided by adult learning principles and popular education philosophy. Evaluation instruments assessed changes related to confidence, intention to use learned skills, usefulness of sessions, and satisfaction with the training. Results demonstrated that a core competency-based training can successfully affect CHWs' perceived confidence and intentions to apply learned content, and can provide a larger social justice context of their role and work. This program demonstrates that a core competency-based framework coupled with CAI-research-specific skill sessions (1) provides skills that CAI-CHWs intend to use, (2) builds confidence, and (3) provides participants with a more contextualized view of client needs and CHW roles.

    Over the past several decades, there has been burgeoning interest and investment in large transdisciplinary (TD) team science initiatives that aim to address complex societal problems. Despite this trend, TD training opportunities in the health sciences remain limited, and evaluations of these opportunities are even more uncommon due to funding constraints. We had the unique opportunity to conduct an exploratory study to examine the potential outcomes and impacts of TD training in a National Cancer Institute-supported initiative for TD research and training-the Transdisciplinary Research on Energetics and Cancer I (TREC I) initiative. This study used a retrospective mixed-methods approach leveraging secondary analysis of existing data sources to learn about TREC trainees' experiences with TREC training, TD research competencies, changes in scholarly productivity, and the associations among these domains. Results indicated that, on average, TREC trainees were satisfied with their TREC mentoring experiences and believed that TREC training processes were effective, in general. Participation in TREC training was associated with TD research competencies, including TD research orientation, positive general attitude toward TD training, development of scientific skills for TD research, and intrapersonal/interpersonal competencies for collaboration. There was also a significant increase in trainees' scholarly productivity from before to after starting in TREC training, as indicated by average annual number of publications and presentations and average number of coauthors per publication. Perceived effectiveness of TREC training was positively correlated with change in average annual number of research presentations from before to after starting in TREC training (r = 0.65, p < 0.05, N = 12), as well as TD research orientation (r = 0.36, p < 0.05), general attitude toward TD training (0.39, p < 0.05), scientific skills for TD research (r = 0

    Although Astronomy is part of the National Curriculum Parameters, it is rarely taught adequately in basic education. In this regard, this research has been developed aiming to investigate contributions to the use of traditional resources combined with digital technologies, in order to create autonomy for future teachers of Natural Sciences and Mathematics in relation to themes in Astronomy. The following steps were taken: i) analysis of educational pedagogical projects (EPP) from licentiate courses at the Federal Institution of Education, Science and Technology in the North of Minas Gerais (FINMG); ii) analysis of students' preconceptions on Astronomy and digital technologies; iii) elaboration of the course and application, developed under the education modality of blended learning, using the teaching proposal of methological pluralism; iv) application and analysis of the final questionnaire. The research subjects were constituted by thirty-two students of Physics, Mathematics and Biological Sciences courses. A mixed methodology with a pre-experimental delineation, combined with content analysis, has been used. The results showed the following: at the IFNMG, only the licentiate course in physics includes Astronomy content in several curriculum subjects; students´ rates of previous knowledge of Astronomy are low, and there are indications of meaningful learning of concepts related to Astronomy. This research sought to contribute to initial teacher training, particularly in relation to Astronomy teaching, proposing new alternatives to promote the teaching of this knowledge area. Furthermore, the intention was to respond to requests of institutions for implementation of blended learning or distance courses, since during the survey it was verified that, although discussions in forums are important, there is a need for such courses to promote on-site meetings conducting practical and manipulative activities.

    We derive the magnetization of a system, Pierre Curie's law, for paramagnetic particles out of thermal equilibrium described by kappa distributions. The analysis uses the theory and formulation of the kappa distributions that describe particle systems with a non-zero potential energy. Among other results, emphasis is placed on the effect of kappa distribution on the phenomenon of having strong magnetization at high temperatures. At thermal equilibrium, high temperature leads to weak magnetization. Out of thermal equilibrium, however, strong magnetization at high temperatures is rather possible, if the paramagnetic particle systems reside far from thermal equilibrium, i.e., at small values of kappa. The application of the theory to the space plasma at the outer boundaries of our heliosphere, the inner heliosheath, leads to an estimation of the ion magnetic moment for this space plasma, that is, μ ≈ 138+/-7 \\text{eV/nT} .

    Individuals with substance use disorders have shown deficits in the ability to implement future intentions, called prospective memory. Deficits in prospective memory and working memory, a critical underlying component of prospective memory, likely contribute to substance use treatment failures. Thus, improvement of prospective memory and working memory in substance use patients is an innovative target for intervention. We sought to develop a feasible and valid prospective memory training program that incorporates working memory training and may serve as a useful adjunct to substance use disorder treatment. We administered a single session of the novel prospective memory and working memory training program to participants (n = 22; 13 men, 9 women) enrolled in outpatient substance use disorder treatment and correlated performance to existing measures of prospective memory and working memory. Generally accurate prospective memory performance in a single session suggests feasibility in a substance use treatment population. However, training difficulty should be increased to avoid ceiling effects across repeated sessions. Consistent with existing literature, we observed superior performance on event-based relative to time-based prospective memory tasks. Performance on the prospective memory and working memory training components correlated with validated assessments of prospective memory and working memory, respectively. Correlations between novel memory training program performance and established measures suggest that our training engages appropriate cognitive processes. Further, differential event- and time-based prospective memory task performance suggests internal validity of our training. These data support the development of this intervention as an adjunctive therapy for substance use disorders. (PsycINFO Database Record

    Full Text Available Abstract Background Mental Health First Aid (MHFA training was developed in Australia to teach members of the public how to give initial help to someone developing a mental health problem or in a mental health crisis situation. However, this type of training requires adaptation for specific cultural groups in the community. This paper describes the adaptation of the program to create an Australian Aboriginal and Torres Strait Islander Mental Health First Aid (AMHFA course and presents an initial evaluation of its uptake and acceptability. Methods To evaluate the program, two types of data were collected: (1 quantitative data on uptake of the course (number of Instructors trained and courses subsequently run by these Instructors; (2 qualitative data on strengths, weaknesses and recommendations for the future derived from interviews with program staff and focus groups with Instructors and community participants. Results 199 Aboriginal people were trained as Instructors in a five day Instructor Training Course. With sufficient time following training, the majority of these Instructors subsequently ran 14-hour AMHFA courses for Aboriginal people in their community. Instructors were more likely to run courses if they had prior teaching experience and if there was post-course contact with one of the Trainers of Instructors. Analysis of qualitative data indicated that the Instructor Training Course and the AMHFA course are culturally appropriate, empowering for Aboriginal people, and provided information that was seen as highly relevant and important in assisting Aboriginal people with a mental illness. There were a number of recommendations for improvements. Conclusion The AMHFA program is culturally appropriate and acceptable to Aboriginal people. Further work is needed to refine the course and to evaluate its impact on help provided to Aboriginal people with mental health problems.

    To assess a training model focused on laparoscopic nephrectomy. 16 residents participated in the study, who attended a training program with a theoretical session (1hour) and a dry (7hours) and a wet lab (13hours). During animal training, the first and last nephrectomies were assessed through the completion time and the global rating scale "Objective and Structured Assessment of Technical Skills" (OSATS). Before and after the course, they performed 3 tasks on the virtual reality simulator LAPMentor (1) eye-hand coordination; 2) hand-hand coordination; and 3) transference of objects), registering time and movement metrics. All participants completed a questionnaire related to the training components on a 5-point rating scale. The participants performed the last nephrectomy faster (P<.001) and with higher OSATS scores (P<.001). After the course, they completed the LAPMentor tasks faster (P<.05). The number of movements decreased in all tasks (1) P<.001, 2) P<.05, and 3) P<.05), and the path length in tasks 1 (P<.05) and 2 (P<.05). The movement speeds increased in tasks 2 (P<.001) and 3 (P<.001). With regards to the questionnaire, the usefulness of the animal training and the necessity of training on them prior to their laparoscopic clinical practice were the questions with the highest score (4.92±.28). The combination of physical simulation and animal training constitute an effective training model for improving basic and advanced skills for laparoscopic nephrectomy. The component preferred by the urology residents was the animal training. Copyright © 2015 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.

    Simulation has played an increasing role in surgical training in recent years, this follows from various reports such as the Chief Medical Officer annual report and Sir John Temple's 'Time for Training' and also from other factors such as increasing focus on efficiency and transparency within the healthcare system. Evidence has shown that simulation can develop and improve technical, clinical, communication and management skills. With technological advances, the quality of simulation has also improved with more realistic models and environment. We have undertaken a review of recent drivers for simulation training in the UK, current techniques and have focused on the application of simulation training within the current UK Neurosurgical curriculum for newly appointed trainees.

    Marie Curie Cancer Care established its nursing service in 1958; however, the service has had little formal evaluation. This study aimed to describe and evaluate the care provided by Marie Curie nurse, and in particular to determine whether patients in their care remained and died at home. Two existing data sets were used: data on all patients referred to the Marie Curie Nursing Services in 147 areas of England, Wales, Scotland and Northern Ireland for 26 months, and data on cancer death registrations in England. A request for a Marie Curie nurse was made for 26,632 patients, 97% of whom had cancer and 11% of whom lived alone. The amount of care provided varied enormously (Marie Curie nurses facilitated home death for many patients. Services need to ensure that mechanisms are in place to achieve data collection. Rigorous prospective evaluation is needed in the future.

    This case report describes the development and implementation of the Train-the-Trainer: Maternal Depression Screening Program (TTT), a novel approach to disseminating perinatal depression screening. We trained screeners according to a standard pyramid scheme of train-the-trainer programs: three experts trained representatives from health care agencies (the TTT trainers), who in turn trained their staff and implemented depression screening at their home agencies. The TTT trainers had little or no prior mental health experience so "enhanced" components were added to ensure thorough instruction. Although TTT was implemented primarily as a services project, we evaluated both the statewide dissemination and the screening rates achieved by TTT programs. Thirty-two social service or health agencies implemented maternal depression screening in 20 counties throughout Iowa; this reached 58.2% of the Iowa population. For the 16 agencies that provided screening data, the average screening rate (number of women screened/number eligible to be screened) for the first 3 months of screening was 73.2%, 80.5% and 79.0%. We compared screening rates of our TTT programs with those of Healthy Start, a program in which screening was established via an intensive consultation model. We found the screening rates in 62.5% of TTT agencies were comparable to those in Healthy Start. Our "enhanced" train-the-trainer method is a promising approach for broadly implementing depression-screening programs in agencies serving pregnant and postpartum women.

  20. The mysterious malleability of titanomagnetite Curie temperatures: An update

    2015-12-01

    Intermediate-composition titanomagnetites (TM30-TM50) have recently been shown to have Curie temperatures (Tc) that depend not only on composition but also quite strongly on thermal history, with increases of 100°C or more in Tc produced by moderate-temperature (300-400° C) annealing in the lab or in slow natural cooling, and equally large decreases produced by more rapid cooling ("quenching") from higher temperatures [e.g., Bowles et al 2013, Nature Communications]. The phenomenon is robustly defined and repeatable, but the underlying mechanism remains enigmatic, although it presumably involves some rearrangement of metal cations within the spinel lattice. New high-and low-temperature measurements, including hysteresis, frequency-dependent AC susceptibility (k(f,T)) and Mössbauer spectroscopy, were carried out to help shed light on the nanoscale mechanisms responsible for the observed changes in Tc. Fabian et al [2015, GJI] have shown for ferrimagnetic compositions in the hematite-ilmenite system that high-T hysteresis measurements exhibit a peak in high-field slope at the Curie temperature, and that the magnitude (area) of this peak is a strong function of cation ordering degree. Our data for synthetic titanomagnetites in quenched and annealed states show some indications of this, although the relationship is not perfectly systematic. On the other hand, our new low-T Mössbauer spectra, measured in the quenched and annealed states, are indistinguishable and argue against any change in site occupancy. Church et al [2011, G3] have proposed that the sharp change in low-T magnetic behavior of intermediate titanomagnetites is a "pinning transition" due to redistribution and localization of ferrous ions within the octahedral sites. Our new k(f,T) results show that the pinning transition in some samples is strongly affected by prior annealing or quenching, suggesting that these treatments affect the intrasite cation distributions. Such an idea is consistent with

    Full Text Available Background: For the shortage of high-quality general practitioners (GPs in China's rural areas, Chinese government has taken steps to encourage rural specialists to participate in transition training for future GPs. Specialists’ initial participation motivations and their perceived deterrents during training may play important roles for their learning engagement in the transition training. This study aimed at revealing the relationships among the variables of initial participation motivations, perceived deterrents in training, and learning engagement. Methods: A questionnaire survey was used in this study. A total of 156 rural specialists who participated in transition training for future GPs filled out the questionnaire, which consisted of the measurements of initial participation motivations, perceived deterrents, and learning engagement in training. The data about specialists’ demographic variables were collected at the same time. Results: The variance of initial escape/stimulations motivation significantly predicted the variance of learning engagement through the full mediating role of perceived deterrents in training. In addition, initial educational preparation motivations predicted the variance of learning engagement directly. Conclusions: Specialists’ initial participation motivations and perceived deterrents in training played important roles for learning engagement in the transition training.

It employs the narrative as a theoretical and methodological perspective, and it utilizes student portfolios, as well as focus groups and semi-structured individual interviews as inputs for data generation. Ten students in their eighth, or final, semester participated in this study. These were the total respondents to a "call for volunteers" among the 2014 graduating class. The results suggest that the students believe the assessment processes of their teaching practices in physical education are disjointed. They feel that the disciplines that allow them to review their own performance during teacher training are more efficient and play a stronger role in their education.

  3. Curie depth vs. flat subduction in Central Mexico

    Manea, Marina; Constantin Manea, Vlad

    2010-05-01

    Forearcs located above active subduction zones are generally characterized by low heat flow values, and this is considered a consequence of the subduction of cold slabs beneath continental plates. In the case of Central Mexico, the geometry of the subducting Cocos plate is quite unusual, the slab runs flat for several hundreds of kilometers before plunging into the asthenosphere. This particular geometry has a strong influence on the temperature distribution of the overriding plate where very low heatflow values are recorded (15-30 mW/m2). In this paper we use the aeromagnetic map of Mexico in order to infer the maximum depth of magnetic source, regarded as Curie depth and corresponding to a temperature of 575-600C°. Our spectral analysis revealed the existence of a deep magnetic source (30-40 km). We compare these results with the thermal structure associated with flat slab subduction in the area. We obtained a good agreement between the two estimates and we conclude that flat slab subduction in Central Mexico controls the maximum depth of magnetic sources in the overriding plate.

    Training in quality improvement (QI) is a pillar of the next accreditation system of the Accreditation Committee on Graduate Medical Education and a growing expectation of physicians for maintenance of certification. Despite this, many postgraduate medical trainees are not receiving training in QI methods. We created the Fellows Applied Quality Training (FAQT) curriculum for cardiology fellows using both didactic and applied components with the goal of increasing confidence to participate in future QI projects. Fellows completed didactic training from the Institute for Healthcare Improvement's Open School and then designed and completed a project to improve quality of care or patient safety. Self-assessments were completed by the fellows before, during, and after the first year of the curriculum. The primary outcome for our curriculum was the median score reported by the fellows regarding their self-confidence to complete QI activities. Self-assessments were completed by 23 fellows. The majority of fellows (15 of 23, 65.2%) reported no prior formal QI training. Median score on baseline self-assessment was 3.0 (range, 1.85-4), which was significantly increased to 3.27 (range, 2.23-4; P = 0.004) on the final assessment. The distribution of scores reported by the fellows indicates that 30% were slightly confident at conducting QI activities on their own, which was reduced to 5% after completing the FAQT curriculum. An interim assessment was conducted after the fellows completed didactic training only; median scores were not different from the baseline (mean, 3.0; P = 0.51). After completion of the FAQT, cardiology fellows reported higher self-confidence to complete QI activities. The increase in self-confidence seemed to be limited to the applied component of the curriculum, with no significant change after the didactic component.

  5. Source modelling of train noise - Literature review and some initial measurements

    A literature review of source modelling of railway noise is reported. Measurements on a special test rig at Surahammar and on the new railway line between Arlanda and Stockholm City are reported and analyzed. In the analysis the train is modelled as a number of point sources with or without directivity and each source is combined with analytical sound propagation theory to predict the sound propagation pattern best fitting the measured data. Wheel/rail rolling noise is considered to be the most important noise source. The rolling noise can be modelled as an array of moving point sources, which have a dipole-like horizontal directivity and some kind of vertical directivity. In general it is necessary to distribute the point sources on several heights. Based on our model analysis the source heights for the rolling noise should be below the wheel axles and the most important height is about a quarter of wheel diameter above the railheads. When train speeds are greater than 250 km/h aerodynamic noise will become important and even dominant. It may be important for low frequency components only if the train speed is less than 220 km/h. Little data are available for these cases. It is believed that aerodynamic noise has dipole-like directivity. Its spectrum depends on many factors: speed, railway system, type of train, bogies, wheels, pantograph, presence of barriers and even weather conditions. Other sources such as fans, engine, transmission and carriage bodies are at most second order noise sources, but for trains with a diesel locomotive engine the engine noise will be dominant if train speeds are less than about 100 km/h. The Nord 2000 comprehensive model for sound propagation outdoors, together with the source model that is based on the understandings above, can suitably handle the problems of railway noise propagation in one-third octave bands although there are still problems left to be solved.

    2014-03-15

    More than 50 Member States have requested assistance from the International Atomic Energy Agency (IAEA) to help them develop the necessary competencies and skills that will allow them to implement technically viable, safe, secure and cost-effective radioactive waste management (RWM) solutions. At the present time the IAEA provides numerous opportunities for the training of managers and experts representing national programmes, regulatory bodies, and organizations related to RWM, and staff of national regulatory bodies responsible for licensing and inspection of such facilities, either through bilateral agreements or through the mechanism of thematic networks. The training events may be lecture based or comprise hands-on training, or may be a combination of the two. However, it is recognised that there are some limitations in the current approach. In order to overcome these limitations, the IAEA is committed to identify and utilise alternative and more cost effective avenues for the delivery of its training. To this end a decision has been made to develop a comprehensive RWM curriculum that jointly covers aspects of both safety and technology with an appropriate balance and that ensures that the two dimensions are delivered in a complimentary and consistent manner, including integration where appropriate. The training materials that will result from the development of the curriculum will be delivered through the medium of the internet and personal computers (eLearning) and also through extended face-face courses to be delivered in Regional Centres of Learning (which are still to be established). The curriculum will be developed collaboratively between the IAEA, international experts and the learning centres. (orig.)

    1977-02-01

    The c- and a-axis linear thermal expansivities of high purity single crystals of gadolinium were measured in the temperature range 270/sup 0/K to 320/sup 0/K. Length changes were translated to capacitance changes with a modified normal geometry 3-terminal capacitance dilatometer. An ac 3-terminal capacitance bridge was employed to measure nominal 10 pF capacitances to a precision of 10/sup -7/ pF, which corresponds to a relative length change sensitivity of 10/sup -10/. A 25 ohm platinum resistance thermometer was used to detect the dilatometer temperature to a precision of 10 ..mu..K with an ac resistance bridge. The c-axis expansivity was negative and had a large (approximately equal to 10/sup -4/ K/sup -1/) peak at 293.435/sup 0/K, while the a-axis expansivity was positive and had a smaller (approximately equal to 10/sup -5/ K/sup -1/) peak at 293.363/sup 0/K. The values of the Curie temperatures (T/sub c/'s) and critical point exponents for the c- and a-axis crystals were obtained from fitting power law equations to the expansivities.

The JARG Young Investigator Forum has three primary goals: first, to increase opportunities for trainees and young investigators to contribute as researchers and writers. Trainees will be invited to publish mini-reviews based on their area of research interest/expertise and will have the opportunity to indicate "in-training" when submitting manuscripts as first author Educational research pertaining to reproductive medicine training will be added to the purview of the journal. Second, the Young Investigator Forum will increase opportunities for trainees to serve as journal reviewers and will provide mentorship throughout the peer review process. Third, trainees will have the unique opportunity to gain editorial experience by serving as a "guest editor" of the Young Investigator Forum, overseeing all editorial aspects of their assigned particular issue. Through authorship, peer review, and editorial experience, we seek to nurture the academic skills that are critical to a well-rounded career. The JARG Young Investigator Forum aims to foster career development for a generation of trainees who represent the future of reproductive medicine, and here, we outline the primary goals and objectives of the initiative.

    Major resuscitation councils endorse the use of the laryngeal mask airway (LMA) by paramedics for lifesaving airway interventions. Learning and maintaining adequate skill level is important for patient safety. The aim of this project was to develop a training program that provides student paramedics with initial knowledge and experience in LMA insertion skills but equally important to provide ongoing skill retention. After ethics approval and informed consent, 55 first year Paramedic degree students watched a manufacturer's LMA instruction video and practiced insertion in three different part task trainers. Six months later, subjects were randomized to an intervention (reviewing the video and 10 minutes unsupervised practice) or control group before participating in a high-fidelity simulated clinical scenario. For equity of training, the control group received the intervention after the scenario. Main outcomes measured were time to insertion; success rate; and LMA skill retention (sum of LMA orientation; cuff inflation; bite block; securing; patient positioning; and overall subject performance). Fifty subjects completed the study. Those in the intervention group displayed significantly shorter insertion times (P = 0.029), fewer attempts to achieve success (P = 0.033), and had significantly higher LMA skill performance levels (P = 0.019) at 6 months. We devised a short intervention based on our training program using a video and practice in part task trainers. In an assessment using high-fidelity simulation, we demonstrated significant improvements in maintenance of LMA insertion skills in student paramedics at 6 months. Our model of just-in-time assessment and reinforcement of training prevents skill decay and has implications for healthcare skills training in general.

    Full Text Available The pace of change in our world poses to school a new way to address the problems of our world. This research pretend to deepen in the ideas that teachers in initial training have about to work socioenvironmental problems in Primary classrooms. The study was conducted in two Spanish Universities. We opted for open-ended questionnaire and data analysis with SPSS and Atlas.Ti. The data suggest that the lack of consensus between topics that are relevant and the topics which may or may not be in the stage of Primary generate controversy and debate. This leads us to reflect on the role of education today.

    Full Text Available The european convergence process demands and promotes a transformation of the teaching-learning processes in favour of a centred-on-competences model that gives our students a higher profile in the action. The competences for the treatment of information, learning and digital integration are an important task in the training processes of future teachers if we really want that our schools walk at the same time as society. From the standpoints of other researches and the thoughtful opinions of students, we go deeply into these tasks, assessing necessities, chances and restrictions that promote these actions.

  6. Initial and Further Education: Substitutes or Complements? Differences in Continuing Education and Training over the Life-Course of European Workers

    2005-11-01

    This investigation examines the place of initial and further education in continuing education and training over the life-course of workers across Europe. The evidence presented demonstrates that in countries with a strong orientation towards vocational education, participation in continuing education and training among employees is higher than in countries that mainly provide general education. Moreover, it can be seen that the effect of the vocational orientation of the education system increases over the life-course of workers. The conclusion of this investigation is that further education complements rather than substitutes for initial education. This implies that national education and training policies meant to encourage lifelong learning should not only attempt to expand or redirect training received by already experienced workers, but also try to facilitate participation in initial vocational training.

    The convergence between the Indian and Eurasian plates has developed the world's extreme topography and has also resulted in the occurrence of large earthquakes in the region. The April 25, 2015 (Mw 7.8) earthquake in central Nepal is the largest earthquake that has been recorded in the Nepal Himalaya since 1934. The earthquake caused thousands of people to die and massive destruction of famous heritage-structures in and around kathmandu and was attributed to the interations between the Indian and Eurasian plates. The crustal thermal structure which can be inferred from the Curie-point depths is critial to understand the seismotectonics and subduction in the Indian-Himalayan region. We present our inversion of Curie-point depths of the Indian-Himalayan region based on fractal spectral analyses both from aeromagnetic and satellite data. The first magnetic anomaly model used for estimatiion of Curie-point depths is the EMAG2 model, which has a resolution of 2-arc minute and an altitude of 4 km above the geoid. The second magnetic anomaly model is the CHAMP lithospheric model MF6. The third and the last magnetic anomaly model is the NGDC-720 lithospheric model, which is based on both the EMAG2 and MF6 models, has the smallest wavelength of 56 km. We first test variable windows sizes of 100.8×100.8 km2, 201.6×201.6 km2 and 302.4×302.4 km2 to estimate the Curie-point depths and then take the average of the results from these three different window sizes as the final Curie depths for the EMAG2 and MF6 models, respectively. The differences between the two Curie depths estimations from the EMAG2 and MF6 models mostly range within about ±4 km except for that in the Central Tibetan Plateau and Northeast India. This result shows that the NGDC-720 lithospheric model which contains both the EMAG2 and MF6 models is valid for the Curie-point estimation in the Indian-Himalayan region. The average Curie depths estimated from the NGDC-720 lithospheric model show small values in

    The effect of Gd doping and O deficiency on the electronic structure, exchange interaction, and Curie temperature of EuO in the cubic and tetragonal phases is studied by means of density functional theory. For both defects, the Curie temperature is found to exhibit a distinct maximum as a function of the defect concentration. The existence of optimal defect concentrations is explained by the interplay of the on-site, RKKY, and superexchange contributions to the magnetism.

    A growing body of evidence suggests that action videogames could enhance a variety of cognitive skills and more specifically attention skills. The aim of this study was to develop a novel adaptive videogame to support the rehabilitation of the most common consequences of traumatic brain injury (TBI), that is the impairment of attention and executive functions. TBI patients can be affected by psychomotor slowness and by difficulties in dealing with distraction, maintain a cognitive set for a long time, processing different simultaneously presented stimuli, and planning purposeful behavior. Accordingly, we designed a videogame that was specifically conceived to activate those functions. Playing involves visuospatial planning and selective attention, active maintenance of the cognitive set representing the goal, and error monitoring. Moreover, different game trials require to alternate between two tasks (i.e., task switching) or to perform the two tasks simultaneously (i.e., divided attention/dual-tasking). The videogame is controlled by a multidimensional adaptive algorithm that calibrates task difficulty on-line based on a model of user performance that is updated on a trial-by-trial basis. We report simulations of user performance designed to test the adaptive game as well as a validation study with healthy participants engaged in a training protocol. The results confirmed the involvement of the cognitive abilities that the game is supposed to enhance and suggested that training improved attentional control during play.

    Maria Skłodowska-Curie--a Nobel Prize winner in chemistry--the elements of learning of chemistry gained just by a dint of work of more than ten months in Warsaw in the Institute of Industry and Agriculture Museum. The Nobel Prize concerned a contribution to the progress of chemistry through the discovery of radium and polonium, separation of radium and study of properties of this amazing element. It was awarded for an extremely arduous work, during which the chemical reactions being the principles of analytical chemistry were realized. Unlike to a typical analytical procedure, an initial attempt here was the thousands of kilograms of uranium ore: pitchblende. The final effect was small amounts of new elements: polonium and radium. Both the knowledge and the intuition of the researcher let her have a triumph. The difficulties she experienced because the properties of the searched chemical elements could only be evaluated thanks to the knowledge on other chemical elements. A significant achievement was the determination of the samples by means of radioactivity measurement, which gave rise to radiochemical analytical methods. An extreme analytical precision was demanded in multiple processes of fractional crystallization and precipitation which finally led to the calculation of the atomic mass of radium.

    Appropriate feedback plays an important role in optimising mammographic interpretation training whilst also ensuring good interpretation performance. The traditional keyboard, mouse and workstation technical approach has a critical limitation in providing supplementary image-related information and providing complex feedback in real time. Augmented Reality (AR) provides a possible superior approach in this situation, as feedback can be provided directly overlaying the displayed mammographic images so making a generic approach which can also be vendor neutral. In this study, radiological feedback was dynamically remapped virtually into the real world, using perspective transformation, in order to provide a richer user experience in mammographic interpretation training. This is an initial attempt of an AR approach to dynamically superimpose pre-defined feedback information of a DICOM image on top of a radiologist's view, whilst the radiologist is examining images on a clinical workstation. The study demonstrates the feasibility of the approach, although there are limitations on interactive operations which are due to the hardware used. The results of this fully functional approach provide appropriate feedback/image correspondence in a simulated mammographic interpretation environment. Thus, it is argued that employing AR is a feasible way to provide rich feedback in the delivery of mammographic interpretation training.

    Agility to schedule and execute cell culture manufacturing campaigns quickly in a multi-product facility will play a key role in meeting the growing demand for therapeutic proteins. In an effort to shorten campaign timelines, maximize plant flexibility and resource utilization, we investigated the initiation of cell culture manufacturing campaigns using CHO cells cryopreserved in large volume bags in place of the seed train process flows that are conventionally used in cell culture manufacturing. This approach, termed FASTEC (Frozen Accelerated Seed Train for Execution of a Campaign), involves cultivating cells to high density in a perfusion bioreactor, and cryopreserving cells in multiple disposable bags. Each run for a manufacturing campaign would then come from a thaw of one or more of these cryopreserved bags. This article reviews the development and optimization of individual steps of the FASTEC bioprocess scheme: scaling up cells to greater than 70 × 10(6) cells/mL and freezing in bags with an optimized controlled rate freezing protocol and using a customized rack configuration. Flow cytometry analysis was also employed to understand the recovery of CHO cells following cryopreservation. Extensive development data were gathered to ensure that the quantity and quality of the drug manufactured using the FASTEC bioprocess scheme was acceptable compared to the conventional seed train process flow. The result of offering comparable manufacturing options offers flexibility to the cell culture manufacturing network.

    Regular participation in organized youth sports does not ensure adequate exposure to skill- and health-related fitness activities, and sport training without preparatory conditioning does not appear to reduce risk of injury in young athletes. Current trends indicate that widespread participation in organized youth sports is occurring at a younger age, especially in girls. Current public health recommendations developed to promote muscle strengthening and bone building activities for youth aged 6 yr and older, along with increased involvement in competitive sport activities at younger ages, has increased interest and concern from parents, clinicians, coaches, and teachers regarding the optimal age to encourage and integrate more specialized physical training into youth development programs. This review synthesizes the latest literature and expert opinion regarding when to initiate neuromuscular conditioning in youth and presents a how-to integrative training conceptual model that could maximize the potential health-related benefits for children by reducing sports-related injury risk and encouraging lifelong, regular physical activity.

Among the objectives of the study, We highlighted: unveiling the contradictions and the theoretical-epistemological assumptions that guide these courses; contribute to the discussions on teacher training courses for basic education; reflect critically on the educational policies that deal on teacher training. We used as sources of examining the proposals for teacher of UNEB, campus of Ipiaú-BA, and UESB, campus of Jequié-BA, and legal documents such as LDBEN and resolutions CNE/C1/2002, CNE/C2/2002 . The discussion was reference in the documents of courses that guide the teachers to the top level in UNEB and UESB. We present an analysis of the subjects of the curriculum, showing its limits and possibilities. We reveal what epistemological matrices that subsidise the proposals and indicate elements able to have us understand why and how such a structure is underway. We conclude that the format of these courses does not take into account elements which seriously undermine the pedagogical work, among them: the release of the exercise teacher with time available for study.

    Under the sponsorship of a pharmaceutical firm, a distance-learning course on Quality Management methods was developed at the University of Murcia (Spain) and offered nationwide to primary health care physicians working in the public system. A total of 7104 physicians (47.7% of the census) signed up (at least one in 92.2% of the health centres). The course content follows the author's model of quality improvement, monitoring and design trilogy, but focuses mainly on methods for a quality improvement cycle using a learning-by-doing and problem-solving approach. The unexpected success of this initiative has led us to reflect on the interest in learning about quality improvement methods shown by physicians, the usefulness of the distance-learning approach, and also to continue the project with new initiatives such as: a summary poster, software containing all the necessary tools and data analysis for quality improvement, and a manual.

    Learning Together is primarily an educational intervention, where paediatric registrars [SpRs] and General Practice (GP) registrars [GPSTs] see children together in a primary care setting. Over a six month period in 2013/2014, 44 learning pairs were set up mainly in North East and Central London. Proof of concept for the model at scale was achieved. Reported learning demonstrated: clinical learning themes of new knowledge, skill and communication skills; and collaborative themes of ongoing collaboration, satisfaction with team working and change in attitudes. These themes were identified in both sets of trainees. The self-reported learning is backed up by the results of a retrospective notes review of four common conditions based on NICE guidelines; constipation, asthma, feverish illness and eczema (CAFE). Guidance adherence improved from 57% before the intervention in solo GP training consultations to 72% during the joint clinic intervention (p Learning Together in its South London extension.

    Nitrate (NO3-) supplementation resulting in higher plasma nitrite (NO2-) is reported to lower resting mean arterial blood pressure (MAP) and oxygen uptake (VO2 ) during submaximal exercise in non-athletic populations, whereas effects in general are absent in endurance-trained individuals. To test whether physiologic effects of NO3- supplementation depend on local muscular training status or cardiovascular fitness, male endurance-trained cyclists (CYC, n=9, VO2 -max: 64±3 mL/min/kg; mean±SD) and recreational active subjects serving as a control group (CON, n=8, 46±3 mL/min/kg), acutely consumed nitrate-rich beetroot juice ([NO3-] ~9 mmol) (NIT) or placebo (PLA) with assessment of resting MAP and energy expenditure during moderate intensity (~50% VO2 -max) and incremental leg cycling (LEG-ex) and arm-cranking exercise (ARM-ex). NIT increased (PVO2 (~2.60 L/min), ARM-ex VO2 (~1.14 L/min), and resting MAP (~87 mm Hg) remained unchanged for CYC, and similarly for CON, no changes were observed for LEG-ex VO2 (~2.03 L/min), ARM-ex VO2 (~1.06 L/min), or resting MAP (~85 mm Hg). VO2 -max was not affected by supplementation, but incremental test peak power was higher (P<.05) in LEG-ex for CYC in NIT relative to PLA (418±47 vs 407±46 W). In both CYC and CON, high initial baseline values and small increases in plasma NO2- after NIT may have lowered the effect of the intervention implying that muscular and cardiovascular training status is likely not the only factors that influence the physiologic effects of NO3- supplementation.

    Effect of pressure on the Curie temperature T{sub C} of the Mn-rich Heusler alloys Mn{sub 2}RuSn and Mn{sub 2}PdSn has been investigated by measuring the temperature dependence of initial permeability at various pressures up to 10 kbar. It was found that the Curie temperatures of Mn{sub 2}RuSn and Mn{sub 2}PdSn decrease with increasing pressure. The pressure derivatives of T{sub C} were estimated to be −0.59 K/kbar for Mn{sub 2}RuSn and −0.80 K/kbar for Mn{sub 2}PdSn. On the basis of the experimental results, the relationship between the magnetic transition temperature and the Mn-Mn distance is discussed.

    Purpose: To evaluate the influence of CAD for the evaluation of CT colonography (CTC) datasets by inexperienced readers during the attendance of a dedicated hands-on training course. Method and materials: Twenty-seven radiologists inexperienced in CTC (11 with no CTC training at all, 16 having previously reviewed no more than 10 CTC cases overall) attended a hands-on training course based on direct teaching on fifteen workstations (four Advantage Windows 4.4 with Colon VCAR software, GE; six CADCOLON, Im3D; five ColonScreen (Toshiba/Voxar) with ColonCAD{sup TM} API, Medicsight). During the course, readers were instructed to analyze 26 CTC cases including 38 colonic lesions obtained through low-dose MDCT acquisitions, consisting of 12 polyps sized less than 6 mm, 9 polyps sized between 6 and 10 mm, 12 polyps sized between 11 mm and 30 mm, and 5 colonic masses sized >3 cm. CTC images were reviewed by each reader both in 2D and 3D mode, respectively by direct evaluation of native axial images and MPR reconstructions, and virtual endoscopy or dissected views. Each reader had 15 min time for assessing each dataset without CAD, after which results were compared with those provided by CAD software. Global rater sensitivity for each lesion size before and after CAD usage was compared by means of two-tailed Student's t test, while sensitivity of each single reader before and after CAD usage was assessed with the McNemar test. Results: For lesions sized <6 mm, global rater sensitivity was 0.1852 {+-} 0.1656 (mean {+-} SD) before CAD-assisted reading and 0.2345 {+-} 0.1761 after CAD (p = 0.0018). For lesions sized 6-9 mm, sensitivity was 0.2870 {+-} 0.1016 before CAD-assisted reading and 0.3117 {+-} 0.1099 after CAD (p = 0.0027). For lesions sized 10-30 mm, sensitivity was 0.5308 {+-} 0.2120 before CAD-assisted reading and 0.5637 {+-} 0.2133 after CAD (p = 0.0086), while for lesions sized >30 mm, sensitivity before CAD-assisted reading was 0.3556 {+-} 0.3105 and did not

    Eighty-four heavy drinkers who responded to a newspaper recruitment advertisement were randomly assigned to receive either (a) training in a Moderate Drinking protocol via an Internet-based program (www.moderatedrinking.com) and use of the online resources of Moderation Management (MM; www.moderation.org) or (b) use of the online resources of MM alone. Follow-ups are being conducted at 3, 6, and 12 months. Results of the recently completed 3-month follow-up (86% follow-up) indicated both groups significantly reduced their drinking based on these variables: standard drinks per week, percent days abstinent, and mean estimated blood alcohol concentration (BAC) per drinking day. Both groups also significantly reduced their alcohol-related problems. Relative to the control group, the experimental group had better outcomes on percent days abstinent and log drinks per drinking day. These short-term outcome data provide evidence for the effectiveness of both the Moderate Drinking Web application and of the resources available online at MM in helping heavy drinkers reduce their drinking and alcohol-related problems.

    Different review articles support the usefulness and effectiveness of mindfulness techniques in health and wellbeing. In this paper we present a first prototype of a mobile application to help with the training and practice of mindfulness, taking into account the lacks detected in a previous literature review. Our aim was to measure acceptance and perceived quality, as well as gather data about app usage. Their dependence on demographic variables and the change in mindful level was also measured. Two versions of a new application were developed, "Mindfulness" and "Mindfulness Sci". The application has been tested in two pilot studies: in traditional face-to-face mindfulness groups and in individual and independent use. 3977 users were involved in this study: 26 in the first trial during an 8-week usage period and 3951 in the second trial during 17 months. In the first study, participants assessed the app with high scores. They considered it as a helping tool for mindfulness practice, user-friendly and with high quality of use. The positive perception was maintained after 8-weeks meditation workshops, and participants considered that its use could contribute to obtain benefits for mental and physical health. In the second study, we found rather weak associations between usage time and age, nationality and educational level. The mindful level showed a weak positive correlation with the session accomplished but slightly above the boundary of statistical significance (p-value=0.051). Videos and information stood out as the most accessed resources. Up to our knowledge, this is the first app developed with the help of health professionals in Spanish that could be used with a general aim, in health and wellbeing. The results are promising with a positive evaluation in face-to-face and independent use situations. Therefore, the number of potential users is enormous in a global worldwide context.

    As the macro behavior of the strength of exchange interaction, state of the art of Curie temperature Tc, which is directly proportional to the exchange integrals, makes sense to the high-frequency and high-reliability microwave devices. Challenge remains as finding a quantitative way to reveal the relationship between the Curie temperature and the exchange integrals for doped barium hexaferrites. Here in this report, for La-substituted barium hexaferrites, the electronic structure has been determined by the density functional theory (DFT) and generalized gradient approximation (GGA). By means of the comparison between the ground and relative state, thirteen exchange integrals have been calculated as a function of the effective value Ueff. Furthermore, based on the Heisenberg model, the molecular field approximation (MFA) and random phase approximation (RPA), which provide an upper and lower bound of the Curie temperature Tc, have been adopted to deduce the Curie temperature Tc. In addition, the Curie temperature Tc derived from the MFA are coincided well with the experimental data. Finally, the strength of superexchange interaction mainly depends on 2b-4f1, 4f2-12k, 2a-4f1, and 4f1-12k interactions.

    The Arabian shield is a Precambrian complex of igneous and metamorphic rocks located approximately one-third of the way across the western Arabian Peninsula, with uncommon exposures along the Red Sea coast. We used aeromagnetic data acquired by others over the past several decades to estimate the depth to the Curie temperature isotherm throughout this region. Our goal was to further understand the lithospheric structure, thermal activity, and seismicity to assist in geothermal exploration. We also compared the Curie temperature isotherm with the crustal thickness to investigate the possibility that mantle rocks are magnetic in some parts of the Arabian shield. Depths to the Curie isotherm were estimated by dividing the regional aeromagnetic grid into 26 overlapping windows. Each window was then used to estimate the shape of the power spectrum. The windows had dimensions of 250 × 250 km to allow investigation of depths as deep as 50 km. The results show the presence of a Curie isotherm at a depth of 10-20 km near the Red Sea, increasing to 35-45 km in the interior of the Arabian shield. The Curie isotherm generally lies above the Moho in this region but deepens into the mantle in some locations, notably beneath the Asir Terrane.

    Key component of the Next Generation Safeguards Initiative (NGSI) launched by the National Nuclear Security Administration is the development of human capital to meet present and future challenges to the safeguards regime. An effective university-level education in safeguards and related disciplines is an essential element in a layered strategy to rebuild the safeguards human resource capacity. Two pilot programs at university level, involving 44 students, were initiated and implemented in spring-summer 2008 and linked to hands-on internships at LANL or LLNL. During the internships, students worked on specific safeguards-related projects with a designated Laboratory Mentor to provide broader exposure to nuclear materials management and information analytical techniques. The Safeguards and Nuclear Material Management pilot program was a collaboration between the Texas A&M University (TAMU), Los Alamos National Laboratory (LANL) and Lawrence Livermore National Laboratory (LLNL). It included a 16-lecture course held during a summer internship program. The instructors for the course were from LANL together with TAMU faculty and LLNL experts. The LANL-based course was shared with the students spending their internship at LLNL via video conference. A week-long table-top (or hands-on) exercise on was also conducted at LANL. The student population was a mix of 28 students from a 12 universities participating in a variety of summer internship programs held at LANL and LLNL. A large portion of the students were TAMU students participating in the NGSI pilot. The International Nuclear Safeguards Policy and Information Analysis pilot program was implemented at the Monterey Institute for International Studies (MIIS) in cooperation with LLNL. It included a two-week intensive course consisting of 20 lectures and two exercises. MIIS, LLNL, and speakers from other U.S. national laboratories (LANL, BNL) delivered lectures for the audience of 16 students. The majority of students were

    The behavior of a three-dimensional isotropic Heisenberg ferromagnet in the presence of a magnetic field H is investigated in the random phase approximation (RPA) near the Curie temperature T{sub c}. It is shown that the magnetization M at the Curie temperature T{sub c} is described by the law M(T=T{sub c})∼H{sup 1/5} and the initial magnetic susceptibility χ{sub 0} at temperatures T≥T{sub c} is given by χ{sub 0}(T≥T{sub c})∼(T−T{sub c}){sup −2}. It means that in the RPA the critical exponents for a three-dimensional Heisenberg ferromagnet coincide with the critical exponents for the Berlin-Kac spherical model of a ferromagnet rather than with the critical exponents of the mean field approximation (MFA). Hence it follows as well that, when a magnetic field H is risen from H=0 to H=H{sub a}, the magnetic entropy S{sub M} will be decreased as ΔS{sub M}(T=T{sub c})∼−H{sub a}{sup 4/5} at the Curie temperature T{sub c} and as ΔS{sub M}(T>T{sub c})∼−(T−T{sub c}){sup −3}H{sub a}{sup 2} at temperatures T>T{sub c}.

  18. Variations in Moho and Curie depths and heat flow in Eastern and Southeastern Asia

    2016-03-01

    The Eastern and Southeastern Asian regions witness the strongest land-ocean and lithosphere-asthenosphere interactions. The extreme diversity of geological features warrants a unified study for a better understanding of their geodynamic uniqueness and/or ubiquity from a regional perspective. In this paper we have explored a large coverage of potential field data and have detected high resolution Moho and Curie depths in the aforementioned regions. The oldest continental and oceanic domains, i.e. the North China craton and the Pacific and Indian Ocean have been found thermally perturbed by events probably linked to small-scale convection or serpentinization in the mantle and to numerous volcanic seamounts and ridges. The thermal perturbation has also been observed in proximity of the fossil ridge of the western Philippine Sea Basin, which shows anomalously small Curie depths. The western Pacific marginal seas have the lowest Moho temperature, with Curie depths generally larger than Moho depths. The contrary is true in most parts of easternmost Eurasian continent. Magmatic processes feeding the Permian Emeishan large igneous province could have also been genetically linked to deep mantle/crustal processes beneath the Sichuan Basin. The regionally elongated magnetic features and small Curie depths along the Triassic Yangtze-Indochina plate boundary suggest that the igneous province could be caused by tectonic processes along plate margins, rather than by a deep mantle plume. At the same time, we interpret the Caroline Ridge, the boundary between the Pacific and the Caroline Sea, as a structure having a continental origin, rather than as hotspot or arc volcanism. The surface heat flow is primarily modulated by a deep isotherm through thermal conduction. This concordance is emphasized along many subduction trenches, where zones of large Curie depths often correspond with low heat flow. Local or regional surface heat flow variations cannot be faithfully used in inferring

Disagreement was more frequent for proposals from Economics/Social Sciences and Humanities panels. Greater disagreement was observed for proposals with lower average IER scores. CR scores for proposals with initial disagreement were also significantly lower. Proposals with a large absolute difference between the average IER and CR scores (≥10 points; n=368, 1.5% generally had lower CR scores. An inter-correlation matrix of individual raters' scores of evaluation criteria of proposals indicated that these scores were, in general, a reflection of raters' overall scores. Our analysis demonstrated a good internal consistency and general high agreement among raters. Consensus meetings appear to be relevant for particular panels and subsets of proposals with large differences among raters' scores.

    Clinical studies have shown that biofeedback-assisted relaxation positively influences the treatment outcomes of sleep disturbance. However, there are only few studies reporting the timing of relaxation training initiation, and the relationships between the timing of initiation and the effectiveness of relaxation remain unclear. The aim of this study was to determine the optimal timing for initiating nurse-led biofeedback-assisted relaxation on hospitalized coronary heart disease patients with sleep disturbance. An experimental pretest and repeated posttest design was used to compare the effectiveness of nurse-led biofeedback-assisted relaxation. A total of 128 patients with coronary heart disease were randomly assigned to 1 of 4 groups: morning group, night group, morning-night group, or control group. Outcome measures included self-report of sleep-related indicators, the scores of the Pittsburgh Sleep Quality Index (PSQI) and the Zung's Self-rating Anxiety Scale (SAS), and the dosage of sleep medication used. A 2-way analysis of variance and a simple effect test were used to analyze the differences among the 4 groups. No significant differences could be detected at baseline. Compared with the control group, the nurse-led biofeedback-assisted relaxation yielded a greater benefit for patients in the 3 intervention groups. Group and time factors (pretest-protest) could explain the variation in the effectiveness of this program (main effect P sleep latency, experienced fewer awakenings, reported higher sleep quality, and used significantly fewer sleep medications than the morning group did (F = 32.97, P sleep quality and decrease the need for of sleep medications in hospitalized patients with sleep disturbance.

    The magnetic properties of dilute magnetic semiconductors (DMS) are calculated by using the local density approximation +U(LDA+U) method. In the LDA+U, occupied d-states in (Ga, Mn)As are predicted at lower energy than in the LDA and p-d exchange interaction explains calculated concentration dependence of Curie temperature very well. In (Ga, Mn)N, unoccupied d states are predicted at higher energy by LDA+U, resulting in higher Curie temperatures than in LDA at high concentrations due to the suppression of the anti-ferromagnetic super-exchange interaction.

    Random matrices are widely and successfully used in physics for almost 60-70 years, beginning with the works of Dyson and Wigner. Although it is an old subject, it is constantly developing into new areas of physics and mathematics. It constitutes now a part of the general culture of a theoretical physicist. Mathematical methods inspired by random matrix theory become more powerful, sophisticated and enjoy rapidly growing applications in physics. Recent examples include the calculation of universal correlations in the mesoscopic system, new applications in disordered and quantum chaotic systems, in combinatorial and growth models, as well as the recent breakthrough, due to the matrix models, in two dimensional gravity and string theory and the non-abelian gauge theories. The book consists of the lectures of the leading specialists and covers rather systematically many of these topics. It can be useful to the specialists in various subjects using random matrices, from PhD students to confirmed scientists.

  11. Low-temperature dynamics of the Curie-Weiss Model: Periodic orbits, multiple histories, and loss of Gibbsianness

    CERN Document Server

    Ermolaev, Victor

    2010-01-01

    We consider the Curie-Weiss model at a given initial temperature in vanishing external field evolving under a Glauber spin-flip dynamics corresponding to a possibly different temperature. We study the limiting conditional probabilities and their continuity properties and discuss their set of points of discontinuity (bad points). We provide a complete analysis of the transition between Gibbsian and non-Gibbsian behavior as a function of time, extending earlier work for the case of independent spin-flip dynamics. For initial temperature bigger than one we prove that the time-evolved measure stays Gibbs forever, for any (possibly low) temperature of the dynamics. In the regime of heating to low-temperatures from even lower temperatures, when the initial temperature is smaller than the temperature of the dynamics, and smaller than 1, we prove that the time-evolved measure is Gibbs initially and becomes non-Gibbs after a sharp transition time. We find this regime is further divided into a region where only symmetr...

Esta relación incluyó desde el desarrollo de procedimientos de extracción para diversas sustancias radiactivas, hasta la promoción de su propio laboratorio industrial. La actividad industrial de Curie se aviene mal con su imagen heroica de científica pura, sacrificada y carente de medios, imagen que, paradójicamente, se retrotrae a las campañas de Curie en los años 1920 por dotar a su laboratorio con «medios de acción industriales». Se verá que los valores dominantes del medio científico francés favorecieron la propagación selectiva de la imagen heroica de Curie, que fue luego aceptada acríticamente por la historiografía de la física del siglo XX.

    2012-07-01

    Baccalaureate nursing students often experience high levels of stress during training that may result in psychological or emotional impairment during their professional life ultimately affecting the quality of patient care they provide. Clinical instructors provide the needed support and guidance for students to relieve stress and promote a positive clinical experience. The aim of this study was to identify the level and types of stress perceived by baccalaureate nursing students in Jordan in their initial period of clinical practice and to identify the coping strategies that students used to relieve their stress. This descriptive cross-sectional study was conducted with 181 nursing students' representative of second year undergraduate students from two universities in Jordan. Proportions and t-tests were used to analyze the data. The results showed that the source of stress for these students came mainly from assignment work and the clinical environment. The most common coping strategy used by students was problem-solving behaviour followed by staying optimistic and transference attention from the stressful situation to other things while avoidance was the least frequent used.

    2003-07-01

    An important point of the actions inside the European framework to achieve the harmonisation of the training programmes and recognition was included in the European directive 96/29/Euratom which includes definition and specific tasks of the European Qualified Expert on Radiation Protection (RP). Basic syllabus for training of those experts was developed in the communication 98/C 133/03 concerning BSS applications. Although, in the Spanish education system, the training and recognition requirements of the high level qualified experts on RP was defined since 1977, until 2001, the figure of the Technical Qualified Expert on RP does not appear in the legal framework. In December 2002, a new regulation of the Spanish Regulatory Body, CSN, about qualifications to obtain the recognition of RP Expert in Spain (both high qualified and technical RP experts) was published. Concerning the qualified expert on RP, (RP Officer), responsible of the RP Service, which takes charge of the effective protection and advise radioactive and nuclear facilities in Rp aspects,has to be authorised by the regulatory body. to obtain the RP officer diploma, conceded by the CSN, an initial training of 300 hours and a three-year minimum experience are required (for X-ray installation a 6-month experience is enough). The technical qualified expert on RP is the worker who carried out the tasks in the a RP Service under the supervision of the RP officer. A Technician Qualified Expert on RP does not need an specific accreditation of the Regulatory Body, but an initial RP training and a three-month minimum experience are required and has hold a certificate by the RP officer. Continuous training is also required and as well has to receive a certificate from the RP officer. Since 1977, The Institute for energy Studies has been implementing specific training courses for those professionals who want to obtain the diploma of RP officer (high degree qualified RP expert), conceded by the CSN.

    To investigate residents' self-reported satisfaction level with their proficiency in extracapsular cataract extraction (ECCE) surgery and the initial barriers to learning the procedure. This is a single-centre prospective descriptive case series involving eight first-year ophthalmology residents in Singapore National Eye Center. We recorded the demographics, frequency of review by the residents of their own surgical videos and their satisfaction level with their proficiency at each of the ECCE steps using a 5-point Likert scale. All ECCE surgical videos between October 2013 and May 2014 were collected and analysed for the overall time taken for the surgery and the time taken to perform the individual steps of the procedure. The mean age of the residents was 27.6 ± 1.5 years and 62.5% (5/8) were women. More than half (62.5%, 5/8) reviewed their own surgical videos while 37.5% (3/8) discussed the surgical videos with their peers or supervisors. Of the ECCE steps, the residents were most dissatisfied with their proficiency in performing irrigation and aspiration (87.5%, 7/8), followed by suturing (62.5%, 5/8), intraocular lens insertion (62.5%, 5/8) and tin can capsulotomy (62.5%, 5/8). The average time taken for each ECCE case was 55.0 ± 12.2 min and, of all the steps, most time was spent on suturing (20.5 ± 6.8 min), followed by irrigation and aspiration (5.5 ± 3.6 min) and tin can capsulotomy (3.3 ± 1.8 min). The first-year ophthalmology residents were most dissatisfied with their proficiency in irrigation/aspiration, suturing and tin can capsulotomy. More training needs to be directed to these areas during teaching sessions in the operating room, wet laboratory or cataract simulation training sessions.

    Based on cortisol release, a variety of situations to which domestic horses are exposed have been classified as stressors but studies on the stress during equestrian training are limited. In the present study, Warmblood stallions (n=9) and mares (n=7) were followed through a 9 respective 12-week initial training program in order to determine potentially stressful training steps. Salivary cortisol concentrations, beat-to-beat (RR) interval and heart rate variability (HRV) were determined. The HRV variables standard deviation of the RR interval (SDRR), RMSSD (root mean square of successive RR differences) and the geometric means standard deviation 1 (SD1) and 2 (SD2) were calculated. Nearly each training unit was associated with an increase in salivary cortisol concentrations (pCortisol release varied between training units and occasionally was more pronounced in mares than in stallions (p<0.05). The RR interval decreased slightly in response to lunging before mounting of the rider. A pronounced decrease occurred when the rider was mounting, but before the horse showed physical activity (p<0.001). The HRV variables SDRR, RMSSD and SD1 decreased in response to training and lowest values were reached during mounting of a rider (p<0.001). Thereafter RR interval and HRV variables increased again. In contrast, SD2 increased with the beginning of lunging (p<0.05) and no changes in response to mounting were detectable. In conclusion, initial training is a stressor for horses. The most pronounced reaction occurred in response to mounting by a rider, a situation resembling a potentially lethal threat under natural conditions.

    and 2001/19/EC, the directives of the European Parliament and of the Council on the mutual recognition of professional qualifications of European doctors currently in force, as well as the impending directive 2005/36/EC, which has to be translated into national law until October 2007, do not include transfusion medicine, blood transfusion or immunohaematology at all. Other medical specialities, which like our field, are not common to all member states of the European Union, are listed in the above mentioned directives with the minimum length of training and minimal requirements for the qualifications. Examples include clinical biology, biological haematology, microbiology-bacteriology, biological chemistry, immunology, thoracic, paediatric or vascular surgery as well as physiotherapy, stomatology, neuro-psychiatry, dermato-venerology, occupational medicine, allergology, geriatrics, gastro-enterological surgery, community medicine, nuclear medicine, pharmacology, accident and emergency medicine or tropical medicine. Most of the above are medical specialities in some member states, but not in all. A concerted initiative inaugurated by the European Network of Transfusion Medicine Societies (EuroNet-TMS) and the European Blood Alliance (EBA) aims to compile the situation of the transfusion medicine speciality throughout Europe. A preliminary summary of the current situation in 15 European states was prepared in 2005 after a first set of questions, which was sent out by us via the EBA platform. The authors appreciate Clair Watts' compilation of the answers provided by the 15 European colleagues. A summary of these answers is depicted in Table 1. However, the initiative aims at a more complex analysis of the different requirements and constituent parts of the qualification in transfusion medicine in different countries. A long-term objective of this initiative might be to introduce the transfusion medicine specialisation into the above mentioned EC directives in order to

    Motivational enhancement therapy (MET) can be defined most simply as the "….combination of Motivational Interviewing (MI) with assessment feedback…." (Miller & Rollnick, 2013, p. 250). MET has a clear evidence-base promoting its use especially for treatment of substance use disorders (SUDs). Despite its efficacy and utility, MET is not widely used in clinical settings. In 2012, to facilitate the dissemination of MET, the Veterans Health Administration [VHA; the health care component of the U.S. Department of Veterans Affairs (VA)] launched a national training program that provided competency-based training in MET to VA staff working in SUD specialty care clinics. All VA facilities are required to implement EBPs for SUDs, such as MET, and ensure that they are available to veterans. This paper describes the VA MET training program and examines the impact of the MET training program on participants' knowledge of MET and self-reported MET skills. We review the components of the training and consultation and discuss adaptations made from the Project MATCH MET model to a real-world clinical setting. Of the 264 training participants we trained 2012-2013, 213 (81%) successfully completed all requirements of the training program, including requirements for demonstrating competency and attending at least 75% of scheduled consultation calls. After completion of the training program, approximately 85% of the clinicians reported implementing MET often (either 1-3 times per week or daily). Furthermore, we saw significant increases in MI knowledge from pretraining assessment to post-workshop and from pretraining to post-consultations. Additional training program details and revisions are discussed.

    We consider a magnetic impurity in two different S=1/2 Heisenberg bilayer antiferromagnets at their respective critical interlayer couplings separating Néel and disordered ground states. We calculate the impurity susceptibility using a quantum Monte Carlo method. With intralayer couplings in only one of the layers (Kondo lattice), we observe an anomalous Curie constant C*, as predicted on the basis of field-theoretical work [S. Sachdev, Science 286, 2479 (1999)10.1126/science.286.5449.2479]. The value C* = 0.262 +/- 0.002 is larger than the normal Curie constant C=S(S+1)/3. Our low-temperature results for a symmetric bilayer are consistent with a universal C*.

    The effect of the magnetization fluctuations on the resistivity of GaMnAs near the Curie temperature TC was experimentally studied. It is shown that the determination of TC from the maximum of the temperature derivative of the resistivity is valid for the samples with a high concentration of free carries. Whereas, for the samples with low concentration of free carriers the TC coincides with the resistivity maximum. The magnetic specific heat for T>TC demonstrates the crossover from the one dimensional to the three dimensional critical behavior when the temperature become closer to the Curie temperature. This is explained by the formation of the ferromagnetic phase in the paramagnetic side of the phase transition which is started from Mn-Mn dimers oriented along one direction.

    High Curie temperaturepiezoelectricthin films of xBiInO3-(1-x)PbTiO3 (x = 0.10, 0.15, 0.20, and 0.25) were prepared by pulsed laser deposition. It was found that the tetragonality of films decreased with increasing BI content. The dielectric constant and transverse piezoelectric coefficient (e31,f ) exhibit the highest values of 665 and -13.6 C/m(2) at x = 0.20. Rayleigh analyses were performed to identify the extrinsic contributions to dielectric nonlinearity with different x. The composition with x = 0.20 also exhibits the largest extrinsic contributions to dielectric nonlinearity. The Curie temperature (TC ) is increased with increasing x content from 558 to 633 °C; TC at x = 0.20 is about 584 °C.

    As the most famous woman scientist of the twentieth century, there has been no shortage of books and articles on the life and career of Marie Curie (1867-1934). Her role as director of a laboratory-based research school in the new scientific field of radioactivity, a field which embraced both chemistry and physics, however, has never been examined. In recent years, there has been a growing interest in the question of research schools, and Morrell, Ravetz, Geison, and Klosterman, amongst others, have written on this subject. Using, in part, the methodology of Morrell, this paper investigates the role of Marie Curie as a school director in the Paris Faculty in the years 1907-14, examining the work and characteristics of her school and assessing her effectiveness as a director.

    X-ray line broadening is found to be an effective parameter to estimate the strain associated with rare earth ion (Gd3+)-doped polycrystalline bismuth vanadate(Bi2VO5.5). The strain increases with increasing Gd3+ concentration. It is anisotropic and found to be maximum in (111) plane. The Curie temperature which is known to decrease with increase in the rare earth ion concentration in these compounds is correlated with increase in strain.

    Using full-potential local-orbital minimum-basis along with spin-polarized relativistic Korringa-Kohn-Rostoker methods, we study the electronic, Fermi surface, Curie temperature and optical properties of Zr2CoAl alloy. The alloy with Li2AgSb and Cu2MnAl structures are compared in terms of magnetic properties, and the electronic structures in two structures are also discussed. According to the calculated electronic states, it finds that the Zr2CoAl with Li2AgSb structure is half-metallic ferromagnet with an integral magnetic moment of 2.00μB , meanwhile we also notice the d-d and p-d hybridizations are responsible for the formation of minority-spin gap, furthermore, the fat-bands are applied to discuss the mixture between d and p electrons in the vicinity of the Fermi level. The Fermi surfaces related to the valence bands are constructed, and it is found that the spin-up valence bands 26, 27 and 28 across the Fermi energy dominate the nature of electrons. By mapping the system onto a Heisenberg Hamiltonian, we obtain the exchange coupling parameters, and observe that the Zr(A)-Co(C) and Zr(A)-Zr(B) interactions provide a major contribution for exchange interactions. Based on the calculated exchange coupling parameters, the Curie temperature is estimated to be 287.86 K at equilibrium, and also the dependence of Curie temperature on lattice constant related to the tunable Curie temperature in Zr2CoAl alloy is studied. Finally, we report the optical properties of Zr2CoAl alloy, and present the photon energy dependence of the absorption, the optical conductivity and the loss function.

    Sr{sub 2}FeMoO{sub 6} and related double perovskites are nowadays intensely investigated due to their potential in the field of spintronics. It has been previously shown that the Curie temperature (T {sub C}) of double perovskites can be increased by injecting carriers in the conduction band. We report here on an alternative approach to reinforce the magnetic interaction, and thus raise T {sub C}. It can be suspected that the introduction of Fe excess in the Fe-Mo sub-lattice, which would lead into the appearance of nearest neighbour Fe-O-Fe antiferromagnetic spin coupling, could reinforce the next-near neighbour Fe-O-Fe-O-Fe ferromagnetic ordering and thus raise the Curie temperature. The plausibility of this mechanism was checked, in the first place, by means of Monte Carlo simulations. Afterwards, Nd{sub 2x}Ca{sub 2-2x}Fe{sub 1+x}Mo{sub 1-x}O{sub 6} series was prepared and fully characterized, being found that the Curie temperature rises as much as {delta}T {sub C} {approx} 75 K when the Fe content is increased. We argue that this is a genuine magnetic exchange effect, not related neither to steric distortions nor band filling.

    We study the critical behavior for inhomogeneous versions of the Curie-Weiss model, where the coupling constant {J_{ij}(β)} for the edge {ij} on the complete graph is given by {J_{ij}(β)=β w_iw_j/( {sum_{kin[N]}w_k})}. We call the product form of these couplings the rank-1 inhomogeneous Curie-Weiss model. This model also arises [with inverse temperature {β} replaced by {sinh(β)} ] from the annealed Ising model on the generalized random graph. We assume that the vertex weights {(w_i)_{iin[N]}} are regular, in the sense that their empirical distribution converges and the second moment converges as well. We identify the critical temperatures and exponents for these models, as well as a non-classical limit theorem for the total spin at the critical point. These depend sensitively on the number of finite moments of the weight distribution. When the fourth moment of the weight distribution converges, then the critical behavior is the same as on the (homogeneous) Curie-Weiss model, so that the inhomogeneity is weak. When the fourth moment of the weights converges to infinity, and the weights satisfy an asymptotic power law with exponent {τ} with {τin(3,5)}, then the critical exponents depend sensitively on {τ}. In addition, at criticality, the total spin {S_N} satisfies that {S_N/N^{(τ-2)/(τ-1)}} converges in law to some limiting random variable whose distribution we explicitly characterize.

    Full Text Available Introduction: This is an empirical article aiming at defining the changes of motor fitness in children practicing swimming at early stage of training in year-long training cycle. Proper selection of candidates to practice certain sports is a very complex process. One needs to select from the very large population of children, girls and boys, characterized by certain features, including somatic and motor features, which developed in a longstanding process of training, will lead them to become champions. The purpose of the research: The purpose of the research was to define the changes of motor fitness in girls’ practicing swimming at early stage of training in year-long training cycle. Material and Methods: The subjects to the research were 85 girls aged 7 (1st year of primary school, including 36 girls in swimming group and 49 girls in control group. 36 of them belonged to swimmers’ group- all girls were members of the Municipal Swimming Club in Szczecin. Control group consisted of 49 girls, who attended the same elementary schools. The examinations were carried out twice in the 2009-2010 academic year. The most reliable and accurate indirect test- EUROFIT Test Battery-was used. Results : The research revealed changes in both groups (Sw, C in terms of all eight tests. Examination II proved statistically significant improvement of results in both groups (Sw, C in comparison to Examination I. The dynamics of changes in general balance, flexibility, static force, functional force, running agility, was bigger in the girls who practiced swimming. As the speed of movement of upper limb, explosive force and thorax force are concerned; the differences of results in both examinations were similar in both groups (swimming group and control group. Progressive changes in motor fitness of the examined groups are a positive phenomenon in the development of child’s young organism. Conclusions: Swimming training significantly affected the dynamics of

    The influence of plastic pre-straining on the mechanical training process of Ni–Mn–Ga single crystals with a non-modulated martensite structure was examined using uniaxial quasi static compression tests and electron backscatter diffraction technique. Firstly, the optimal pre-straining temperature, for which a large plastic strain can be imposed to as-grown crystals with low flow stress and low rate of strain hardening, was established. Then, the maximum value of plastic pre-straining which allows performing successful room temperature mechanical training was found to be of about 20% of total sample thickness reduction. Below this value, training process leads to single variant state, which is able to accommodate true plastic strain of about 0.14 in each step of further training. Above 20% of deformation a multiple martensite variant state of characteristic triangular arrangements is generated. The latter structure cannot practically afford any plastic accommodation during further training; thus the training process fails to operate.

  10. The Relationship of a Pilot's Educational Background, Aeronautical Experience and Recency of Experience to Performance In Initial Training at a Regional Airline

    Science.gov (United States)

    Shane, Nancy R.

    The purpose of this study was to determine how a pilot's educational background, aeronautical experience and recency of experience relate to their performance during initial training at a regional airline. Results show that variables in pilots' educational background, aeronautical experience and recency of experience do predict performance in training. The most significant predictors include years since graduation from college, multi-engine time, total time and whether or not a pilot had military flying experience. Due to the pilot shortage, the pilots entering regional airline training classes since August 2013 have varied backgrounds, aeronautical experience and recency of experience. As explained by Edward Thorndike's law of exercise and the law of recency, pilots who are actively using their aeronautical knowledge and exercising their flying skills should exhibit strong performance in those areas and pilots who have not been actively using their aeronautical knowledge and exercising their flying skills should exhibit degraded performance in those areas. Through correlation, chi-square and multiple regression analysis, this study tests this theory as it relates to performance in initial training at a regional airline.

    Thermal demagnetization in the vicinity of the Curie temperature of silver and sodium manganite nanoparticles, as well as copper-nickel and palladium-nickel alloy nanoparticles were studied by both static magnetic measurements and by electron spin resonance (ESR). ESR data indicate that some magnetic ordering remains even above the Curie temperature, determined by static magnetometry. Mechanisms of thermal demagnetization in alloy nanoparticles appear to be different from that in manganites.

  12. Organizational impact of evidence-informed decision making training initiatives: a case study comparison of two approaches

    Background The impact of efforts by healthcare organizations to enhance the use of evidence to improve organizational processes through training programs has seldom been assessed. We therefore endeavored to assess whether and how the training of mid- and senior-level healthcare managers could lead to organizational change. Methods We conducted a theory-driven evaluation of the organizational impact of healthcare leaders’ participation in two training programs using a logic model based on Nonaka’s theory of knowledge conversion. We analyzed six case studies nested within the two programs using three embedded units of analysis (individual, group and organization). Interviews were conducted during intensive one-week data collection site visits. A total of 84 people were interviewed. Results We found that the impact of training could primarily be felt in trainees’ immediate work environments. The conversion of attitudes was found to be easier to achieve than the conversion of skills. Our results show that, although socialization and externalization were common in all cases, a lack of combination impeded the conversion of skills. We also identified several individual, organizational and program design factors that facilitated and/or impeded the dissemination of the attitudes and skills gained by trainees to other organizational members. Conclusions Our theory-driven evaluation showed that factors before, during and after training can influence the extent of skills and knowledge transfer. Our evaluation went further than previous research by revealing the influence—both positive and negative—of specific organizational factors on extending the impact of training programs.

  13. Large deviations of the finite-time magnetization of the Curie-Weiss random-field Ising model

    2017-08-01

    We study the large deviations of the magnetization at some finite time in the Curie-Weiss random field Ising model with parallel updating. While relaxation dynamics in an infinite-time horizon gives rise to unique dynamical trajectories [specified by initial conditions and governed by first-order dynamics of the form mt +1=f (mt) ] , we observe that the introduction of a finite-time horizon and the specification of terminal conditions can generate a host of metastable solutions obeying second-order dynamics. We show that these solutions are governed by a Newtonian-like dynamics in discrete time which permits solutions in terms of both the first-order relaxation ("forward") dynamics and the backward dynamics mt +1=f-1(mt) . Our approach allows us to classify trajectories for a given final magnetization as stable or metastable according to the value of the rate function associated with them. We find that in analogy to the Freidlin-Wentzell description of the stochastic dynamics of escape from metastable states, the dominant trajectories may switch between the two types (forward and backward) of first-order dynamics. Additionally, we show how to compute rate functions when uncertainty in the quenched disorder is introduced.

    The structures of Y2Fe17-xCrx are simulated by the ab initio potentials. The site preference of Cr atom in Y2Fe17 is evaluated and the order is determined as 4f, 12j, which is close to the experimental result. Based on the site preference behavior, the calculated parameters and the atom sites of Y-Fe-Cr system are studied. The result corresponds well to observed data. Further, the DOS of the relaxed structures are calculated and the variation in Curie temperature is explained qualitatively by the spin-fluctuation theory.

    It is well known that the magnetizations as a function of the valence electron number per atom of 3d transition metal substitutional alloys form the so-called Slater-Pauling curve. Similarly, the Curie temperatures of these alloys also show systematic behaviour against the valence electron number. Though this fact has long been known, no attempt has been made so far to explain this behaviour from first principles. In this paper we calculate T(C) of 3d transition metal alloys in the framework of first-principles electronic structure calculation based on the local density approximation.

    1999-01-01

    The FeZrB amorphous alloys for simulating the intergranular amorphous phase in the nanocrystalline Fe89Zr7B4 soft magnetic materials were obtained by mechanical alloying of a mixture of elemental Fe, Zr and B powdersfor 25 h. It is shown that the Curie temperature of the simulated intergranular phase alloy is much lower than thatof the intergranular phase with the same chemical composition in the nanocrystalline Fe89Zr7B4 alloy. The possiblemechanism is mainly due to the strong ferromagnetic exchange force among the nanocrystalline α-Fe grains.

    The effect of microscopic Mn cluster distribution on the Curie temperature (Tc) is studied using density-functional calculations. We find that the calculated Tc depends crucially on the microscopic cluster distribution, which can explain the abnormally large variations in experimental Tc values from a few K to well above room temperature. The partially dimerized Mn_2-Mn_1 distribution is found to give the highest Tc > 500 K, and in general, the presence of the Mn_2 dimer has a tendency to enh...

    Recent national reports and commentaries on the current status and needs of the U.S. biomedical research workforce have highlighted the limited career development opportunities for predoctoral and postdoctoral trainees in academia, yet little attention is paid to preparation for career pathways outside of the traditional faculty path. Recognizing this issue, in 2013, the U.S. National Institutes of Health (NIH) Common Fund issued a request for application titled "NIH Director's Biomedical Research Workforce Innovation Award: Broadening Experiences in Scientific Training (BEST)." These 5-yr 1-time grants, awarded to 17 single or partnering institutions, were designed to develop sustainable approaches to broaden graduate and postgraduate training, aimed at creating training programs that reflect the range of career options that trainees may ultimately pursue. These institutions have formed a consortium in order to work together to develop, evaluate, share, and disseminate best practices and challenges. This is a first report on the early experiences of the consortium and the scope of participating BEST programs. In this report, we describe the state of the U.S. biomedical workforce and development of the BEST award, variations of programmatic approaches to assist with program design without BEST funding, and novel approaches to engage faculty in career development programs. To test the effectiveness of these BEST programs, external evaluators will assess their outcomes not only over the 5 yr grant period but also for an additional 10 yr beyond award completion.

    The possibility of employing the ferromagnetic–paramagnetic phase transitions of magnetic materials to calibrate temperature during spark plasma sintering (SPS) was investigated using pure Fe and Fe–50Co alloy. A sharp and repeatable change was observed in the electrical current profile at the Curie temperature (T{sub c}) during both sintering and reheating of the sintered samples. Under a pulsed DC current, an abrupt change in the electrical resistance was observed at T{sub c} due to the sudden changes in the permeability and in turn, the skin depth during heating and cooling. These effects can be used to obtain a more accurate in-situ measurement of the sample temperature than the one provided by the pyrometers that are normally used for SPS processing. The temperature measured using a pyrometer was found to be significantly lower (up to 70 °C) than the actual temperature of the specimen. - Highlights: • Calibration of temperature during spark plasma sintering (SPS) remains a big challenge. • Temperature measured by non-contact pyrometers in SPS is not accurate. • Ferromagnetic materials exhibit abrupt change in permeability at Curie temperature (T{sub c}). • Iron and Fe–Co alloy showed sharp and reproducible changes in SPS electric current profiles at T{sub c}. • Ferromagnetic materials can be successfully used to calibrate pyrometers in SPS.

    N-doped graphene with Curie temperature higher than room temperature is a good candidate for nanomagnetic applications. Here we report a kind of N-doped graphene that exhibits ferromagnetic property with high Curie temperature (>600 K). Four graphene samples were prepared through self-propagating high-temperature synthesis (SHS), and the doped nitrogen contents of in the samples were 0 at.%, 2.53 at.%, 9.21 at.% and 11.17 at.%. It has been found that the saturation magnetization and coercive field increase with the increasing of nitrogen contents in the samples. For the sample with the highest nitrogen content, the saturation magnetizations reach 0.282 emu/g at 10 K and 0.148 emu/g at 300 K; the coercive forces reach 544.2 Oe at 10 K and 168.8 Oe at 300 K. The drop of magnetic susceptibility at ~625 K for N-doped graphene is mainly caused by the decomposition of pyrrolic N and pydinic N. Our results suggest that SHS method is an effective and high-throughput method to produce N-doped graphene with high nitrogen concentration and that N-doped graphene produced by SHS method is promising to be a good candidate for nanomagnetic applications.

    A series of nickel–copper alloy magnetic nanoparticles with a range of Curie points from 51 °C to 63 °C were prepared by the reduction of intimately mixed nickel and copper oxides in a silica matrix using the sol–gel method. The silica matrix was subsequently removed with an etching solution, assisted by sonication. The alloy nanoparticles were characterized using X-ray diffraction (XRD) analysis, thermogravimetric analysis (TGA/SDTA), thermomagnetic analysis (TMA), transmission electron microscopy (TEM), magnetic measurements (SQUID, vibrating-sample magnetometer) and specific absorption rate measurements (SAR). The synthesized nanoparticles show a size in the range 15–20 nm, exhibited superparamagnetic behavior with a blocking temperature (T{sub B}) of approximately 135 K and a room-temperature magnetization of 3–9 emu/g, depending on the composition. The nanoparticles showed a relatively high effective anisotropy constant (K{sub eff}) and a significant heating ability in an alternating magnetic field. The synthesis method is straightforward and allows the preparation of homogeneous Ni–Cu alloy nanoparticles with a relatively narrow particle size distribution. - Highlights: • Straightforward so-gel synthesis of homogeneous Ni–Cu alloy nanoparticles. • Narrow particle size distribution and controlled Curie point. • Applications in “self-regulating magnetic fluid hyperthermia”. • Heating efficiency of nanoparticles as a function of composition and size.

  14. Conflicting demands in prison education and the need for context-specific, specialist training for prison educators: an account of the work of the Initial Teacher Training project for teachers and instructors in London prisons and offender learning

    Full Text Available Prison Education is regulated by legislative and institutional requirements as are other kinds of Learning and Skill provision, but it is also fundamentally affected by the custodial requirements of the British Legal system. This, together with the relative isolation that teaching staff face within an organisational culture which is peculiar to each prison, produces a learning culture that is very different from that of general Further Education. This paper discusses initial findings of the LONCETT Prison Education Research Project (2008, which aims to identify the specific professional training needs of prison educators in London. Findings from five of the eight prisons in London highlighted two main pedagogic issues that emerged as key aspects of prison education practice which require both specialist training input and further research: the fragmentation which characterises the learner experience; and the emotional stress produced in this environment, which impacts both upon prisoner-learners and teaching staff.

    The fourth International Polar Year (IPY) in 2007/08 provides a unique opportunity to enhance international collaboration in research and education. Here we present an IPY-teaching initiative (AITI), which proposes to develop an interdisciplinary international short course series promoting and fostering education and training of the next generation(s) of scientists and educators interested in natural and social sciences related to Polar Regions; a short course series (GELATI) focusing on the impact of the cryosphere on the Earth system. The main goals of the short course series are to: a) provide education and training for the next generation of graduate students, science teachers, researchers in science related to Polar Regions; b) provide training for junior faculty c) integrate research and education; d) create awareness for Polar Regions related questions in class-rooms and beyond; e) create international partnerships in education and training; f) promote multidisciplinary thinking; g) increase gender diversity in science and teaching; h) encourage minority participation. To achieve these goals it is intended to develop a curriculum of specialized and interdisciplinary courses considering various aspects of science and scientific activities, which study, or are concerned with processes/developments in Polar Regions. Due to the vast dimensions and distribution of Polar Regions across international boundaries as well as the complexity of environmental studies in Polar Regions these courses will internationally pool students and instructors. Pooling of experts and students internationally will not only ensure highest standards but also foster international partnership. To allow the integration of research and teaching and to provide the best possible study environment the up to two to three weeklong, courses will be held at international field stations or will be incorporated into large research projects. To ensure training of the next generation of

    2010-01-01

    A computer-based 'Useful Field of View' (UFOV) training program has been shown to be effective in improving visual processing in older adults. Studies of young adults have shown that playing video games can have similar benefits; however, these studies involved realistic and violent 'first-person shooter' (FPS) games. The willingness of older adults to play such games has not been established. OBJECTIVES: To determine the degree to which older adults would accept playing a realistic, violent FPS-game, compared to video games not involving realistic depiction of violence. METHODS: Sixteen older adults (ages 64-77) viewed and rated video-clip demonstrations of the UFOV program and three video-game genres (realistic-FPS, cartoon-FPS, fixed-shooter), and were then given an opportunity to try them out (30 minutes per game) and rate various features. RESULTS: The results supported a hypothesis that the participants would be less willing to play the realistic-FPS game in comparison to the less violent alternatives (p'svideo-clip demonstrations, 10 of 16 participants indicated they would be unwilling to try out the realistic-FPS game. Of the six who were willing, three did not enjoy the experience and were not interested in playing again. In contrast, all 12 subjects who were willing to try the cartoon-FPS game reported that they enjoyed it and would be willing to play again. A high proportion also tried and enjoyed the UFOV training (15/16) and the fixed-shooter game (12/15). DISCUSSION: A realistic, violent FPS video game is unlikely to be an appropriate choice for older adults. Cartoon-FPS and fixed-shooter games are more viable options. Although most subjects also enjoyed UFOV training, a video-game approach has a number of potential advantages (for instance, 'addictive' properties, low cost, self-administration at home). We therefore conclude that non-violent cartoon-FPS and fixed-shooter video games warrant further investigation as an alternative to the UFOV program

    Ground and aeromagnetic data are combined to characterize the onshore and offshore magnetic properties of the central Philippines, whose tectonic setting is complicated by opposing subduction zones, large-scale strike-slip faulting and arc-continent collision. The striking difference between the magnetic signatures of the islands with established continental affinity and those of the islands belonging to the island arc terrane is observed. Negative magnetic anomalies are registered over the continental terrane, while positive magnetic anomalies are observed over the Philippine Mobile Belt. Several linear features in the magnetic anomaly map coincide with the trace of the Philippine Fault and its splays. Power spectral analysis of the magnetic data reveals that the Curie depth across the central Philippines varies. The deepest point of the magnetic crust is beneath Mindoro Island at 32 km. The Curie surface shallows toward the east: the Curie surface is 21 km deep between the islands of Sibuyan and Masbate, and 18 km deep at the junction of Buruanga Peninsula and Panay Island. The shallowest Curie surface (18 km) coincides with the boundary of the arc-continent collision, signifying the obduction of mantle rocks over the continental basement. Comparison of the calculated Curie depth with recent crustal thickness models reveals the same eastwards thinning trend and range of depths. The coincidence of the magnetic boundary and the density boundary may support the existence of a compositional boundary that reflects the crust-mantle interface.

    Leaders in medical education have increasingly called for the incorporation of cost awareness and health care value into health professions curricula. Emerging efforts have thus far focused on physicians, but foundational competencies need to be defined related to health care value that span all health professions and stages of training. The University of California, San Francisco (UCSF) Center for Healthcare Value launched an initiative in 2012 that engaged a group of educators from all four health professions schools at UCSF: Dentistry, Medicine, Nursing, and Pharmacy. This group created and agreed on a multidisciplinary set of comprehensive competencies related to health care value. The term "competency" was used to describe components within the larger domain of providing high-value care. The group then classified the competencies as beginner, proficient, or expert level through an iterative process and group consensus. The group articulated 21 competencies. The beginner competencies include basic principles of health policy, health care delivery, health costs, and insurance. Proficient competencies include real-world applications of concepts to clinical situations, primarily related to the care of individual patients. The expert competencies focus primarily on systems-level design, advocacy, mentorship, and policy. These competencies aim to identify a standard that may help inform the development of curricula across health professions training. These competencies could be translated into the learning objectives and evaluation methods of resources to teach health care value, and they should be considered in educational settings for health care professionals at all levels of training and across a variety of specialties.

  19. Giant magnetocaloric effect in isostructural MnNiGe-CoNiGe system by establishing a Curie-temperature window

    2013-03-28

    An effective scheme of isostructural alloying was applied to establish a Curie-temperature window in isostructural MnNiGe-CoNiGe system. With the simultaneous accomplishment of decreasing structural-transition temperature and converting antiferromagnetic martensite to ferromagnetic state, a 200 K Curie-temperature window was established between Curie temperatures of austenite and martensite phases. In the window, a first-order magnetostructural transition between paramagnetic austenite and ferromagnetic martensite occurs with a sharp jump in magnetization, showing a magnetic entropy change as large as −40 J kg−1 K−1 in a 50 kOe field change. This giant magnetocaloric effect enables Mn1− x Co x NiGe to become a potential magnetic refrigerant.

    To evaluate the learner's perspectives on a novel workshop programme designed to improve skills in biostatistics, research methodology and critical appraisal in oncology. Trainees were surveyed anonymously at the completion of each annual workshop from 2012 to 2015. In total, 103 trainees in years 2-4 of training in radiation oncology responded, giving a 94% survey response rate. A 1 day workshop, designed by biostatisticians and radiation oncologist facilitators, is the central component of a programme teaching skills in biostatistics, research methods and critical appraisal. This links short didactic lectures about statistical concepts to interactive trainee discussions around discipline-related publications. The workshop was run in conjunction with the major radiation oncology clinical trials group meeting with alternating programmes (A and B). Most of the participants (44-47/47 for A and 48-55/56 for B), reported that their understanding of one or more individual topics improved as a result of teaching. Refinement of the workshop over time led to a more favourable perception of the 'optimal' balance between didactic/interactive teaching: nine of 27 (33%) 'optimal' responses seen in 2013 compared with 23 of 29 (79%) in 2015 (P < 0.001). Commonly reported themes were: clinician facilitators and access to biostatisticians helped contextualise learning and small group, structured discussions provided an environment conducive to learning. Overall, radiation oncology trainees reported positive perceptions of the educational value of this programme, with feedback identifying areas where this resource might be improved. This model could readily be adapted to suit other medical disciplines and/or other training environments, using specialty-specific research to illuminate key statistical concepts.

    Curie-therapy conventionally comes before surgery in the treatment of cervical cancer, either alone or after a concomitant chemotherapy. The authors report a study of the impact of a reverse sequence (surgery before curie-therapy) on the exeresis quality and on the evolution of operable tumours. Among women treated between 2004 and 2009, 40 have been identified who had surgery before curie-therapy. Ages, tumour stages, average doses, and treatment procedures are discussed. The notably high rate of vaginal sections could be reduced or avoided by using the conventional protocol (curie-therapy before surgery). Short communication

  2. Forearc structure in the Lesser Antilles inferred from depth to the Curie temperature and thermo-mechanical simulations

    Imaging deep active volcanic areas remains a challenge in our understanding of their activity and evolution, especially in subduction zones. Study of magnetic anomalies is appropriate to access such dynamics in depth. The magnetic anomaly pattern of the Lesser Antilles Arc (LAA) subduction is studied through Curie Point Depth (CPD), interpreted as the depth of the 580 °C isotherm, and developed to better assess the deep thermal structure of the arc. The depth of the estimated CPD exhibits a complex topography. Keeping in mind the overall uncertainty associated with this method, a main doming is evidenced below the Guadeloupe archipelago. Its apex is shifted towards the ancient arc, suggesting a very hot state of the fore-arc/arc domain. To better understand the LAA thermal state, we perform 2D thermo-mechanical simulations of the subduction zone. Recalling that magnetite is a serpentinization by-product, we simulate water transfer triggered by slab dehydration to test the assumption of fore-arc serpentinization suggested by the positive magnetic anomaly in the vicinity of the Guadeloupe archipelago. In this area, the subduction-induced arc lithosphere hydration and related weakening trigger a fast heating of the upper plate by basal convective removal. This process of fast arc lithosphere thinning may apply where simultaneously the volcanic arc is split in two and normal convergence is high enough. As serpentinization strongly decreases P-wave velocity, we propose a new interpretation of a published seismic profile below Guadeloupe. The seismic layer previously interpreted as the arc lower crust may rather be a layer of serpentinized mantle, as supported by spatial correlations between gravimetric and magnetic anomalies. Consequently, at the scale of Guadeloupe Island, the fore-arc Moho would be shallower than initially assumed, with a dome shape more consistent with both the extensive deformation active since the Oligocene in the inner fore-arc and the CPD doming.

    @@ Above Curie temperature, MnBi crystals are aligned in situ along the c-axis in a Bi matrix by a high fabrication magnetic field Hf of 10 T. Magnetic testing shows a pronounced anisotropy in magnetization in directions normal and parallel to the fabrication field, resulting from the alignment. The successful alignment may result from the fact that the easy magnetization direction is along the c-axis of MnBi and the high fabrication field of 10 T is large enough to rotate the MnBi crystal to this direction even though the temperature is above the Curie temperature.

The research is descriptive and qualitative characteristic. Had as a tool for data collection a questionnaire with closed and open questions. 130 trainees participated in six degree courses of an institution of Paraná Public Higher Education. The results indicate a process of high complexity on the structure and development of supervised curricular internship. The trainees hoped that the curriculum components establish closer to the requirements for the exercise of the teaching profession. There was no evidence is sufficient interaction between the actors involved.

    We report the discovery of ternary CeFe(12-x)Si(x)compounds possessing the ThMn12 structure. The samples were prepared by melt spinning followed by annealing. In contrast to other known Ce Fe-based binary and ternary compounds, CeFe12-xSix compounds exhibit exceptionally high Curie temperatures whose values increase with added Si substitution. The highest T. = 583 K in CeFe10Si2 rivals that of the well-established Nd2Fe14B compound. We ascribe the T-c behavior to a combination of Si-induced 3d band structure changes and partial Ce3+ stabilization. (C) 2014 Published by Elsevier Ltd.

    Polycrystalline Mn5Ge3 thin films were produced on SiO2 using magnetron sputtering and reactive diffusion (RD) or non-diffusive reaction (NDR). In situ X-ray diffraction and atomic force microscopy were used to determine the layer structures, and magnetic force microscopy, superconducting quantum interference device, and ferromagnetic resonance were used to determine their magnetic properties. RD-mediated layers exhibit similar magnetic properties as molecular beam epitaxy-grown monocrystalline Mn5Ge3 thin films, while NDR-mediated layers show magnetic properties similar to monocrystalline C-doped Mn5Ge3Cx thin films with 0.1 ≤ x ≤ 0.2. NDR appears as a complementary metal oxide semi-conductor-compatible efficient method to produce good magnetic quality high-Curie temperature Mn5Ge3 thin films.

    We performed first-principles calculations within density-functional theory to study the structural, electronic, and magnetic properties of Nd-doped ZnO monolayer. The calculated results reveal that Nd-doped ZnO monolayer exhibits stable room temperature ferromagnetism with a large saturation magnetic moment of 3.99 μB per unit in ZnO monolayer. The magnetic property is contributed to the localized f sates of Nd atoms. When two Zn atoms are substituted by two Nd dopants, they tend to form ferromagnetic (FM) coupling and the estimated Curie temperature is higher than room temperature. More interesting, the impurity bands appear within the band gap of ZnO monolayer due to the introduction of Nd dopant. Our results may provide a reference for modifying the material property of ZnO monolayer and are promising as nanoscale building block in spintronic devices.

    The article presents from the perspective of one hundred years the work of Maria Curie-Skłodowska, which in many cases was ahead of the state of knowledge of the time. It opened new horizons and for this reason we made many digressions. The fact of awarding her the Nobel Prize twice is a sensation enough to present the values of careful activity of the Nobel Prize Committee that emphasizes the importance of Maria's achievements. A significant element of Maria Skłodowska-Curie's achievements was still mysterious character of the radiation in her time, and only chemical approach made it possible to organise the phenomena and explain the origin of the radiation. The essence of the research was an arduous separation of components following the track of growing radiation of successive fractions of preparations. This research was a start of the technology of educement of dispersed elements in great mass of materials. We underline the paramount role of the chemical research Maria Skłodowska conducted while still in Warsaw in the laboratories of the Museum of Industry and Agriculture under the guidance of an excellent chemist Józef Jerzy Boguski. Her research in Paris was the origin of the semi-commercial scale in chemistry and setting aside a special shed outside the university building was the beginning of the institutes that now function beyond universities and are key element of scientific and technical progress. Technology of splitting developed by Maria Skłodowska-Curie was applied also by other radiochemists, e.g. By Otto Hahn. Lively movement in radiochemistry of her lifetime resulted in Maria's disputes with e.g. German chemist Marckwald, who questioned the originality of polonium. The scientific disputes like this one Maria won triumphantly although in several others she had to accept opponents' argument, as in the case of radon. Her experiments were planned with utmost rationality as it was with the rejection of the hypothesis saying that radioactivity was

    In the early part of the 20th century, the pioneers of radioactivity research, led by Marie Curie, Ernest Rutherford and Stefan Meyer, formed a Commission internationale des étalons de radium. The Commission made arrangements for the preparation and intercomparisons of the international standards of radium, which were identified as the Paris standard and the Vienna standard. Otto Hönigschmid from Vienna prepared a first set of international secondary standards in 1912 and a second set in 1934. In both instances, these secondary standards were compared by gamma-ray measurements with the Paris and Vienna standards. The usage of these international standards of radium in the 20th century is described.

    The thermal decomposition behavior of terephthalic acid (TA) was investigated by thermogravimetry/differential thermal analysis (TG/DTA) and Curie-point pyrolysis. TG/DTA analysis showed that TA is sublimed at 276°C prior to decomposition. Pyrolysis studies were carried out at various temperatures ranging from 160 to 764°C. Decomposition products were analyzed and their structures were determined by gas chromatography-mass spectrometry (GC-MS). A total of 11 degradation products were identified at 764°C, whereas no peak was observed below 445°C. Benzene, benzoic acid, and 1,1‧-biphenyl were identified as the major decomposition products, and other degradation products such as toluene, benzophenone, diphenylmethane, styrene, benzaldehyde, phenol, 9H-fluorene, and 9-phenyl 9H-fluorene were also detected. A pyrolysis mechanism was proposed based on the findings.

    There is a current need for a change in the attitudes of researchers toward the care and use of experimental animals in India. This could be achieved through improvements in the provision of training, to further the integration of the Three Rs concept into scientific research and into the regulations of the Committee for the Purpose of Control and Supervision of Experiments on Animals (CPCSEA). A survey was performed after participants undertook the Federation of European Laboratory Animal Science Associations (FELASA) Category C-based course on Laboratory Animal Science (in 2013 and 2015). It revealed that the participants subsequently employed, in their future research, the practical and theoretical Three Rs approaches that they had learned. This is of great importance in terms of animal welfare, and also serves to benefit their research outcomes extensively. All the lectures, hands-on practical sessions and supplementary elements of the courses, which also involved the handling of small animals and procedures with live animals, were well appreciated by the participants. Insight into developments in practical handling and welfare procedures, norms, directives, and ethical use of laboratory animals in research, was also provided, through the comparison of results from the 2013 and 2015 post-course surveys.

    Food for humans is one of the most important of all global issues. It is a critical determinant of planetary and individual health, of economic development, of how sustainable energy and water supplies are, and its security a powerful determinant of peace or conflict. Those who assume leadership for the integrity of food and health systems have great responsibility. The IUNS (International Union of Nutritional Sciences), regional and national nutrition science and food technology organizations have concern about the leadership capacity available and required in what are rapidly changing and increasingly demanding circumstances. These include persistent poverty and hunger, climate change which threatens the sustainability of food production and fragile financial systems which are making food less affordable for many. North East Asia (NEA) is a major region for its population size, its economic wealth and disparities, its food production, its life expectancies among the best and its global reach. In 2008, for those of Chinese ancestry and of wider Asian origin, Nutrition Leadership training has been conducted in Hangzhou, Shanghai, Seoul and Taiwan (Hsinchu and Zhunan). Ninety prospective young leaders participated in all. Several successful early career Asian nutrition scientists and professionals served as role models. Senior colleagues acted as mentors for groups of 2 or 3. With mentors, the concept of leadership has been examined, careers and roles explored, knowledge and skills honed for a different future, and plans made to network in mutual support. Early feedback indicates that new opportunities have been created and seized.

  15. Mapping Curie temperature depth in the western United States with a fractal model for crustal magnetization

    2009-01-01

    We have revisited the problem of mapping depth to the Curie temperature isotherm from magnetic anomalies in an attempt to provide a measure of crustal temperatures in the western United States. Such methods are based on the estimation of the depth to the bottom of magnetic sources, which is assumed to correspond to the temperature at which rocks lose their spontaneous magnetization. In this study, we test and apply a method based on the spectral analysis of magnetic anomalies. Early spectral analysis methods assumed that crustal magnetization is a completely uncorrelated function of position. Our method incorporates a more realistic representation where magnetization has a fractal distribution defined by three independent parameters: the depths to the top and bottom of magnetic sources and a fractal parameter related to the geology. The predictions of this model are compatible with radial power spectra obtained from aeromagnetic data in the western United States. Model parameters are mapped by estimating their value within a sliding window swept over the study area. The method works well on synthetic data sets when one of the three parameters is specified in advance. The application of this method to western United States magnetic compilations, assuming a constant fractal parameter, allowed us to detect robust long-wavelength variations in the depth to the bottom of magnetic sources. Depending on the geologic and geophysical context, these features may result from variations in depth to the Curie temperature isotherm, depth to the mantle, depth to the base of volcanic rocks, or geologic settings that affect the value of the fractal parameter. Depth to the bottom of magnetic sources shows several features correlated with prominent heat flow anomalies. It also shows some features absent in the map of heat flow. Independent geophysical and geologic data sets are examined to determine their origin, thereby providing new insights on the thermal and geologic crustal

    Barium ferrite has attracted considerable interest in the fields of permanent magnets and perpendicular magnetic recording due to its strong uniaxial anisotropy and high Curie temperature (T{sub c}). We prepared aluminum doped barium ferrite ceramics (BaAl{sub x}Fe{sub 12−x}O{sub 19}, 0≤x≤6) by the ball mill method. The powder was milled for 96 h, and after forming pellets, annealed for 48 h in air at 1000 °C. The X-ray diffraction (XRD) data show that there are only single hexagonal phases in the samples without any impurity phase. The crystal lattice constants, a and c, were calculated by Cohen's method. Both a and c decrease with increasing x, ranging from 0.588 nm and 2.318 nm to 0.573 nm and 2.294 nm, respectively. A Vibrating Sample Magnetometer (VSM) and Superconducting Quantum Interference Device (SQUID) were used to investigate T{sub c} and magnetic properties of BaFe{sub 12−x}Al{sub x}O{sub 19}. It is found that T{sub c} decreases with increasing x, from 425 °C to 298 °C. It is also found that the saturated magnetization (4πM{sub s}) decreases with increasing x, while the coercivity (H{sub c}) increases with the increase in x. The anisotropy field was also determined from the SQUID measurement. - Highlights: • The Curie temperature and magnetic properties of aluminum doped barium ferrite particles were studied systemically. • The relation between 4πM{sub s} and composition x at 50 K (both experimental value and theoretical calculation) was revealed. • Occupation number for spin up and spin down as a function of temperature was shown. • The relation between 4πM{sub s} and composition x from 50 K to room temperature was revealed.

    Rutile CrO2 is an important half-metallic ferromagnetic material, which is also widely used in magnetic recording. In an attempt to find the conditions, which lead to the increase of the Curie temperature (T C), we study theoretically the band-filling dependence of interatomic exchange interactions in the rutile compounds. For these purposes, we use the effective low-energy model for the magnetic t 2g bands, derived from the first-principles electronic structure calculations in the Wannier basis, which is solved by means of dynamical mean-field theory. After the solution, we calculate the interatomic exchange interactions, by using the theory of infinitesimal spin rotations, and evaluate T C. We argue that, as far as the Curie temperature is concerned, the band filling realized in CrO2 is far from being the optimal one and much higher T C can be obtained by decreasing the number of t 2g electrons (n) via the hole doping. We find that the optimal n is close to 1, which should correspond to the case of VO2, provided that it is crystallized in the rutile structure. This finding was confirmed by using the experimental rutile structure for both CrO2 and VO2 and reflects the general tendency towards ferromagnetism for the narrow-band compounds at the beginning of the band filling. In particular, our results suggest that the strong ferromagnetism can be achieved in the thin films of VO2, whose crystal structure is controlled by the substrate.

    With the implementation of strict 80-hour work week in general surgery training, serious questions have been raised concerning the quality of surgical education and the ability of newly trained general surgeons to independently operate. Programs that were randomized to the interventional arm of the Flexibility In duty-hour Requirements for Surgical Trainees (FIRST) Trial were able to decrease transitions and allow for better continuity by virtue of less constraints on duty-hour rules. Using National Surgical Quality Improvement Program Quality In-Training Initiative data along with duty-hour violations compared with old rules, it was hypothesized that quality of care would be improved and outcomes would be equivalent or better than the traditional duty-hour rules. It was also hypothesized that resident perception of compliance with duty hour would not change with implementation of new regulations based on FIRST trial. Flexible work hours were implemented on July 1, 2014. National Surgical Quality Improvement Program Quality In-Training Initiative information was reviewed from July 2014 to January 2015. Patient risk factors and outcomes were compared between institutional resident cases and the national cohort for comparison. Residents' duty-hour logs and violations during this period were compared to the 6-month period before the implementation of the FIRST trial. The annual Accreditation Council for Graduate Medical Education resident survey was used to assess the residents' perception of compliance with duty hours. With respect to the postoperative complications, the only statistically significant measures were higher prevalence of pneumonia (3.4% vs. 1.5%, p < 0.05) and lower prevalence of sepsis (0% vs. 1.5%, p < 0.05) among cases covered by residents with flexible duty hours. All other measures of postoperative surgical complications showed no difference. The total number of duty-hour violations decreased from 54 to 16. Had the institution not been part of the

    Full Text Available Being centered in the context of initial teachers’ education this article describes and analyzes the speech about the role of the pedagogic practice in the point of view of the different elements that participate in that process. The developed investigation was drawn in both quantitative and qualitative paradigms, involving futures teachers, cooperative teachers (tutors and supervisor teachers. The analysis was essentially descriptive and interpretative. Our greater preoccupation is to understand the meaning that the participants give to a set of questions in the context of the pedagogical practice. The data gathered by the instruments were analyzed with a methodology of content analysis. The analysis allowed obtaining a conceptual picture guided by several categories that show: the conceptions concerning the expectations and fears about profession; the function and organization of the pedagogic practice; and, the cooperative teachers’ role and supervisors’ role. The main results evidence that the component of practice is very important in the preservice teachers’ education. The students in initial formation show positive expectations about profession, but they also point fears. The students value the roles of the tutor and the supervisor, like agents of mediation of the processes of understanding and integration of the different knowledge, and advisors of the dialectic processes of analysis of processes and syntheses associated to the reflection that the young professor must do in his practice. For the agents of the practical education (tutorial and supervisors the practice is defined as a context of fundamental formation in the preparation of the young teacher. With respect to its roles we saw that these are not exactly coincident, but complementary.

    Smoking cessation is a primary method of reducing excess mortality and morbidity. Unfortunately, the vast majority of cessation attempts end in eventual relapse. Relapse-prevention interventions have shown some success at improving the long-term maintenance of tobacco abstinence among individuals motivated to abstain. However, involuntary tobacco abstinence (e.g., military training, hospitalization, incarceration) presents another opportunity for intervention to prevent relapse. During basic military training (BMT), tobacco use is strictly forbidden in all service branches, but tobacco relapse (and initiation) following BMT is extremely high. This paper reports on the design, intervention development, and baseline characteristics of a randomized controlled trial testing minimal interventions designed to prevent tobacco relapse among United States Air Force (USAF) personnel following BMT. Participants are randomized by squadron to receive either a standard smoking-cessation booklet, a new motivation-based booklet designed specifically for USAF personal, or the latter booklet combined with a brief, face-to-face motivational session. Primary outcomes will be self-reported tobacco use at 12 and 24month follow-up. Given that the Department of Defense is the world's largest employer, the potential of leveraging involuntary tobacco abstinence during BMT into extended abstinence has substantial public health significance.

    The emerging field of spintronics would be dramatically boosted if room-temperature ferromagnetism could be added to semiconductor nanostructures that are compatible with silicon technology. Here, we report a high-TC (>400K) ferromagnetic phase of (Ge,Mn) epitaxial layer. The manganese content is 6%, and careful structural and chemical analyses show that the Mn distribution is strongly inhomogeneous: we observe eutectoid growth of well-defined Mn-rich nanocolumns surrounded by a Mn-poor matrix. The average diameter of these nanocolumns is 3nm and their spacing is 10nm. Their composition is close to Ge(2)Mn, which corresponds to an unknown germanium-rich phase, and they have a uniaxially elongated diamond structure. Their Curie temperature is higher than 400K. Magnetotransport reveals a pronounced anomalous Hall effect up to room temperature. A giant positive magnetoresistance is measured from 7,000% at 30K to 200% at 300K and 9T, with no evidence of saturation.

    The opening of the Drake Passage, situated between South America and Antarctica, represents the final stage of the fragmentation of Gondwana supercontinent. It led to the Scotia Arc formation, bordering the Scotia Sea, which is surrounded by fragments of the former continental connection. It is currently composed of Scotia and Sandwich Plates. Shackleton Fracture Zone constitutes its sinistral transpressive western boundary and it is a key structure that accommodates former Phoenix and Scotia Plates' differential movement. The formation of the Drake Passage and the Scotia Sea is considered of great importance to ocean circulation, as it allows the establishment of the Antarctic Circumpolar Current that isolated the Antarctic continent, with strong implications for climate and global changes. Thermal structure of the Earth's crust is one of the main parameters controlling geodynamic processes. There is few information regarding heat flow values on Scotia arc. These values are mainly located in its westernmost, southern and easternmost part, which are not enough to extract conclusions regarding lithospheric thickness variations and asthenospheric flow. Taking advantage of the World Digital Magnetic Anomaly Map Project's compilation we have extracted magnetic anomaly data which fall inside the Scotia Arc and surrounding areas. This magnetic anomaly picture provides the best representation of magnetic properties to date. We propose to use spectral methods on this regional magnetic compilation to obtain depth to the bottom of magnetic sources as a proxy to infer Curie depth and heat flow distribution in the Scotia Sea.

It is also found that the saturated magnetization (4πMs) decreases with increasing x, while the coercivity (Hc) increases with the increase in x. The anisotropy field was also determined from the SQUID measurement.

  8. Cluster Mott insulators and two Curie-Weiss regimes on an anisotropic kagome lattice

    2016-06-01

    Motivated by recent experiments on the quantum-spin-liquid candidate material LiZn2Mo3O8 , we study a single-band extended Hubbard model on an anisotropic kagome lattice with the 1/6 electron filling. Due to the partial filling of the lattice, the intersite repulsive interaction is necessary to generate Mott insulators, where electrons are localized in clusters rather than at lattice sites. It is shown that these cluster Mott insulators are generally U(1) quantum spin liquids with spinon Fermi surfaces. The nature of charge excitations in cluster Mott insulators can be quite different from conventional Mott insulator and we show that there exists a cluster Mott insulator where charge fluctuations around the hexagonal cluster induce a plaquette charge order (PCO). The spinon excitation spectrum in this spin-liquid cluster Mott insulator is reconstructed due to the PCO so that only 1/3 of the total spinon excitations are magnetically active. Based on these results, we propose that the two Curie-Weiss regimes of the spin susceptibility in LiZn2Mo3O8 may be explained by finite-temperature properties of the cluster Mott insulator with the PCO as well as fractionalized spinon excitations. Existing and possible future experiments on LiZn2Mo3O8 , and other Mo-based cluster magnets are discussed in light of these theoretical predictions.

    Full Text Available The dependence of perpendicular magnetization and Curie temperature (Tc of Pt/Co/Pt thin films on the thicknesses of Pt seed (Pts and presence of Ta buffer layer has been investigated in this work. Pt and Co thicknesses were varied between 2 to 8 nm and 0.35 to 1.31 nm (across the spin reorientation transition thickness respectively and the Tc was measured using SQUID magnetometer. We have observed a systematic dependence of Tc on the thickness of Pts. For 8nm thickness of Pts the Co layer of 0.35nm showed ferromagnetism with perpendicular anisotropy at room temperature. As the thickness of the Pts was decreased to 2nm, the Tc went down below 250K. XRD data indicated polycrystalline growth of Pts on SiO2. On the contrary Ta buffer layer promoted the growth of Pt(111. As a consequence Ta(5nm/Pt(3nm/Co(0.35nm/Pt(2nm had much higher Tc (above 300K with perpendicular anisotropy when compared to the same stack without the Ta layer. Thus we could tune the ferromagnetic Tc and anisotropy by varying the Pts thickness and also by introducing Ta buffer layer. We attribute these observations to the micro-structural evolution of Pts layer which hosts the Co layer.

    The realization and application of spintronic devices would be dramatically advanced if room-temperature ferromagnetism could be integrated into semiconductor nanostructures, especially when compatible with mature silicon technology. Herein, we report the observation of such a system - an Si/MnGe superlattice with quantum dots well aligned in the vertical direction successfully grown by molecular beam epitaxy. Such a unique system could take full advantage of the type-II energy band structure of the Si/Ge heterostructure, which could trap the holes inside MnGe QDs, significantly enhancing the hole-mediated ferromagnetism. Magnetic measurements indeed found that the superlattice structure exhibited a Curie temperature of above 400 K. Furthermore, zero-field cooling and field cooling curves could confirm the absence of ferromagnetic compounds, such as Ge8Mn11 (Tc ∼ 270 K) and Ge3Mn5 (Tc ∼ 296 K) in our system. Magnetotransport measurement revealed a clear magnetoresistance transition from negative to positive and a pronounced anomalous Hall effect. Such a unique Si/MnGe superlattice sets a new stage for strengthening ferromagnetism due to the enhanced hole-mediation by quantum confinement, which can be exploited for realizing the room-temperature Ge-based spin field-effect transistors in the future.

    The Marie Curie Cancer Care (2003) Spiritual and Religious Care Competencies for Specialist Palliative Care provide a common language for healthcare practitioners in the nebulous area of spiritual care. The development of a pilot blended learning event, as described in this paper, sought to integrate the competencies into practice by providing opportunities both online and in the classroom to explore this aspect of holistic care in depth. In the planning stages, multiprofessional focus groups determined the level of delivery, and emerging themes shaped the content. Self-awareness and reflection were key features and part of the overall process to improve competency. The features of the virtual learning environment (VLE) used were video, facilitated asynchronous discussion and direct links to key articles and documents, while interactive classroom activities built on prior learning. Evaluation covered all aspects of the course design from participant and facilitator perspectives. Participant comments were overwhelmingly positive in relation to the content and chosen delivery methods with concerns about online learning proving unfounded.

    2003-01-01

    An ab initio approach to the magnetic properties of bulk hexagonal Gd is developed that is based on the local spin-density approximation with the 4f electrons treated as localized core electrons. The effective one-electron problem is solved using the tight-binding linear muffin-tin orbital method in the atomic-sphere approximation with the valence basis consisting of s-, p-and d-type orbitals. The approach leads to a correct description of the ground-state properties like the stability of the ferromagnetic structure, the magnetic moment and the equilibrium lattice constant. Application of a real-space Green-function formalism yields the exchange pair interactions between distant neighbours that are inevitable for quantitative studies of magnetic excitations. The distance dependence and anisotropy of the exchange pair interactions are presented and the Curie temperature in the mean-field approximation is evaluated. The obtained value of 334 K is in much better agreement with the experimental value of 293 K tha...

    We have successfully grown nanoscale Fe2CrAl thin films on polished Si/SiO2 substrates using an ultra-high vacuum deposition with a base pressure of 9×10-10 Torr. The thickness of thin films ranges from 30 to 100 nm. These films exhibit cubic crystal structure with lattice disorder and display ferromagnetic behavior. The Curie temperature is greater than 400 K, which is much higher than that reported for bulk Fe2CrAl. The magnetic moments of the films varies from 2.5 to 2.8 μB per formula unit, which is larger than the reported bulk values. Thus, the disordered nanoscale Fe2CrAl films exhibit strong Fe-Fe exchange interactions through Fe-Cr-Fe and Fe-Al-Fe layers, resulting in both a large magnetization and a high Curie temperature.

    The Dipartimento di Fisica Sperimentale and the Istituto Nazionale di Fisica Nucleare (INFN), Torino, in collaboration with the Institut Curie-Centre de Protontherapie de Orsay (CPO), have developed and built a pixel parallel plate ionization chamber to be used as monitor for the proton therapy beam line at the Institut Curie-CPO (Orsay, France). The sensitive area of the detector is (160x160) mm{sup 2}, with the anode segmented in 1024 square pixels arranged in a 32x32 matrix; the area of each pixel is (5x5) mm{sup 2}. The detector has been placed on the beam line just upstream of the last collimator to monitor the beam shape and to measure the stability and reproducibility of the delivery system. In this paper, we present a detailed description of the detector and the results of a set of preliminary tests.

    2008-10-01

    Using aeromagnetic data acquired in the area from the Cerro Prieto geothermal field, we estimated the depth to the Curie point isotherm, interpreted as the base of the magnetic sources, following statistical spectral-based techniques. According to our results the Curie point isotherm is located at a depths ranging from 14 to 17 km. Our result is somewhat deeper than that obtained previously based only in 2-D and 3-D forward modeling of previous low-quality data. However, our results are supported by independent information comprising geothermal gradients, seismicity distribution in the crust, and gravity determined crustal thickness. Our results imply a high thermal gradient (ranging between 33 and 38 °C/km) and high heat flow (of about 100 mW/m 2) for the study area. The thermal regime for the area is inferred to be similar to that from the Salton trough.

    2010-07-01

    Recent measurements of GaMnAs alloy samples with a very small content of P atoms prepared by ion-implanted pulsed laser melting (II-PLM) [Phys. Rev. Lett. 101, 087203 (2008)10.1103/PhysRevLett.101.087203] have shown surprisingly low Curie temperature as compared to undoped samples. An explanation based on a possible metal-insulator transition at constant Mn doping was proposed based on a dramatic increase of the sample resistivity. However, no quantitative calculations supporting such a picture as concerns the Curie temperature were shown. We will present a parameter-free theory of the Curie temperature (TC) which assumes that possible defects due to the II-PLM such as, e.g., space inhomogeneities, vacancies, clustering, and also conventional compensating defects will reduce the sample hole concentration. Their effect was first qualitatively modeled in the framework of the rigid-band model by adjusting the system Fermi level due to the reduction of the carrier concentration which is considered as a parameter of the theory. In addition, the effect of possible conventional compensating defects, such as, e.g., As and P antisites or P and Mn interstitials was also investigated. TC ’s are calculated within the self-consistent local RPA (SCLRPA) and Monte Carlo (MC) simulations. We will demonstrate that a reasonable agreement of calculated and measured TC can be obtained for reduced hole concentrations which are known to exist in GaMnAs samples. As concerns possible specific defects, we have shown that P and Mn interstitials are particularly effective in the reduction of the sample Curie temperature.

To avoid local overheating, perovskite NPs with a lower Curie temperature (Tc were proposed for use in thermotherapy. However, deposited power decreases when approaching the Curie temperature and consequently may not be sufficient for effective ablation. The goal of the study was to test this hypothesis. Methods: Perovskite NPs (Tc =66°C–74°C were characterized and tested both in vitro and in vivo. In vitro, the cells suspended with NPs were exposed to a HF magnetic field together with control samples. In vivo, a NP suspension was injected into a induced tumor in rats. Distribution was checked by MRI and the rats were exposed to a HF field together with control animals. Apoptosis in the tissue was evaluated. Results and discussion: In vitro, the high concentration of suspended NPs caused an increase of the temperature in the cell sample, leading to cell death. In vivo, MRI confirmed distribution of the NPs in the tumor. The temperature in the tumor with injected NPs did not increase

  20. Differentiation, context and teacher education: the changing profile of trainees on in-service initial teacher training programmes in the lifelong learning sector

    2009-01-01

    Full Text Available Analysis of initial teacher training (ITT student data relating to the University of Huddersfield part-time in-service Cert Ed/PGCE over a three-year period has revealed significant change in the make-up of trainee cohorts. There has been an increase in younger trainees and in trainees very new to teaching, although more experienced and older trainees do continue to enrol. There has also been a considerable shift in the balance of trainees away from further education (FE college staff. These changes have implications for those who manage and deliver teacher education for the sector. It remains of key importance that the curriculum is not experienced as overly ‘FE-college centric’ and that mentoring arrangements acknowledge the needs of trainees from diverse contexts. It is clear that in the delivery of ITT for the lifelong learning sector, increasingly, one size will not comfortably fit all. Within teacher education much emphasis is placed upon the role of differentiation in regard to trainee practice. The changing trainee profile identified requires that teacher education itself unambiguously models a differentiated approach – and, in relation to teacher education for the lifelong learning sector, differentiation must address workplace context.

  1. Curie Temperature and Microstructural Changes Due to the Heating Treatment of Magnetic Amorphous Materials

    Full Text Available Three distinct alloys: Fe86Zr7Nb1Cu1B5, Fe82Zr7Nb2Cu1B8, and Fe81Pt5Zr7Nb1Cu1B5 were characterized both magnetically and structurally. The samples, obtained with spinning roller method as a ribbons 3 mm in width and 20 μm thick, were investigated as-quenched and after each step of a multi steps heating treatment procedure. Each sample was annealed at four steps, fifteen minutes at every temperature, starting from 573K+600K up to +700K depending on type of alloy. Mössbauer spectroscopy data and transmission electron microscope (HRE M pictures confirmed that the as-quenched samples are fully amorphous. This is not changed after the first stages of treatment heating leads to a reduction of free volumes. The heating treatment has a great influence on the magnetic susceptibilities. The treatment up to 600K improves soft magnetic properties: an χ increase was observed, from about 400 to almost 1000 for the samples of alloys without Pt, and from about 200 to 450 at maximum, for the Fe81Pt5Zr7Nb1Cu1B5. Further heating, at more elevated temperatures, leads to magnetic hardening of the samples. Curie temperatures, established from the location of Hopkinson’s maxima on the χ(T curve are in very good agreement with those obtained from the data of specific magnetization, σ(T, measured in a field of 0.75T. As a critical parameter β was chosen to be equal 0.36 for these calculations, it confirmed that the alloys may be considered as ferromagnetic of Heisenberg type. Heating treatment resulted in decreasing of TC. These changes are within a range of several K.

    1999-12-01

    From 1 January 1951 to 30 June 1998, 696 patients presented spontaneously or were referred to the French Institut Curie Radiopathology Unit following a more or less severe accidental irradiation. Of these, 568 patients came from France, while 128 were sent by various foreign countries. The very great majority of irradiation accidents occurred in the workplace, particularly in industry. Interestingly, 'non-nuclear' industry was responsible for three times more events than the nuclear industry. While incidental irradiation of the public by lost radioactive sources was exceedingly rare in France, it seemed to be more frequent in our cohort of foreign patients. Radiation phobia accounted for about 10% of cases in the French cohort, but the number of cases did not seem to increase with time. Overall, the accrual of patients over time appears to be stable, with 10 to 25 new cases consulting each year. Fortunately, a majority of cases corresponded to low-level irradiation (and even no irradiation at all). In the French cohort, only 21.6% of patients, showing deterministic effects, required some form of treatment, with 4.9% considered as 'severe' cases. Not unexpectedly, more patients required treatment in the foreign cohort (35.2%), with 24.2% of severe cases, including four deaths. The main features of this database are consistent with the data previously reported by the IAEA, UNSCEAR and REAC/TS. Although the number of severe cases is small, it should still be considered to be too high, especially as most of these accidents could have been easily avoided if a few basic radioprotection rules had been fully respected.

    We have estimated the Curie Point Depth (CPD) using the average radial power spectrum in a tectonically complex area located in the SW Caribbean basin. Data analyzed came from the World Digital Magnetic Anomaly Map, and three methods have been used to compare results and evaluate uncertainties: Centroid, Spectral Peak, and Forward Modeling. Results show a match along the three methods, suggesting that the CPD values in the area ranging between 6 km and 50 km. The results share the following characteristics: A) High values (> 30 km) are in continental regions; B) There is a trend of maximum CPD values along the SW-NE direction, starting from the Central Cordillera in Colombia to the Maracaibo Lake in Venezuela; C) There is a maximum CPD at the Sierra Nevada de Santa Marta (Colombia) as well as between Costa Rica - Nicaragua and Nicaragua - Honduras borders. The lowest CPD values (coastal regions and offshore. We also tested results by estimating the geothermal gradient and comparing measured observations of the study area. Our results suggest at least five thermal terrains in the SW Caribbean Basin: A) The area that is comprising the Venezuela Basin, the Beata Ridge and the Colombia Basin up to longitude parallel to the Providencia Throat. B) The area that includes zones to the north of the Cocos Ridge and Panam Basin up to the trench. C) The orogenic region of the northern Andes and including areas of the Santa Marta Massif. D) The continental sector that encompasses Nicaragua, northern Costa Rica and eastern of Honduras. E) Corresponds to areas of the northern Venezuela and Colombia, NW of Colombia, the Panamanian territory and the transition zones between the Upper and Lower Nicaragua Rise.

    The American Society of Transplantation Infectious Diseases (ID) Community of Practice has established an education workgroup to identify core components of a curriculum for training specialists in transplant ID. Clinical, laboratory, and research training form the triad of components on which an additional year of ID training, dedicated to the care of solid organ and hematopoietic stem cell transplant recipients, should be based. The recommended training environment would have access to adequate numbers of transplant patients, along with qualified faculty committed to teaching specialized fellows in this area. The learning objectives for both inpatient and outpatient clinical training are presented. The laboratory component requires trainees to attain expertize in utilizing and interpreting cutting-edge diagnostics used in transplant medicine. The research component may involve basic science, and translational or clinical research individualized to the trainee. Finally, suggestions for evaluation of both the fellows and the training program are provided.

  6. Curie's hypotheses concerning radioactivity and the origin of the elements

    Energy Technology Data Exchange (ETDEWEB)

    Kuroda, P.K.

    1999-09-01

    Pierre Curie gave two hypotheses at first; (1) It can be supposed that the radioactive substances borrow the energy, which they release, from an external radiation, and their radiation would then be a secondary radiation, (2) It can be supposed that the radioactive substances draw from themselves the energy which they release. The second hypothesis has shown the more fertile in explaining the properties of the radioactive substances. Consequently, the first hypothesis became more or less forgotten. It appears, however, the first hypothesis should play an important role in explaining the phenomena concerning the origin of the elements. The Oklo Phenomenon has demonstrated that a nuclear fire had once existed on our planet earth and formation of heavy elements was occurring in nature. The author pointed out that the difference in the isotopic compositions of xenon found in meteorites, lunar samples and in the earth's atmosphere can only be explained as due to the alterations of the isotropic compositions of xenon by combined effect of (a) mass-fractionation, (b) spallation, and (c) stellar temperature neutron-capture reactions. The strange xenon components are not isotopically pure substance. Instead, xenon-HL is a mixture of the {sup 244}Pu fission xenon and the xenon whose isotopic compositions is severely altered by a combined effect of the processes (a), (b) and (c) mentioned above. These results also indicate that C1 carbonaceous chondrites, which is generally as the most primitive sample of the solar system material, began to retain its xenon 5.1 billion years ago, when the plutonium to uranium ratio in the solar system was as high as almost 0.6 (atom/atom), while the C2 carbonaceous chondrite began to retain their xenon about 150 million years later and the ordinary chondrites and achondrite about 500 to 600 million years later. This means that the birth of the solar system began soon after the last supernova exploded about 5.1 billion years ago, and the

    To examine if supervised progressive resistance training was superior to home-based exercise in rehabilitation after unicompartmental knee arthroplasty. Single blinded, randomized clinical trial. Surgery, progressive resistance training and testing was carried out at Aarhus University Hospital and home-based exercise was carried out in the home of the patient. Fifty five patients were randomized to either progressive resistance training or home-based exercise. Patients were randomized to either progressive resistance training (home based exercise five days/week and progressive resistance training two days/week) or control group (home based exercise seven days/week). Preoperative assessment, 10-week (primary endpoint) and one-year follow-up were performed for leg extension power, spatiotemporal gait parameters and knee injury and osteoarthritis outcome score (KOOS). Forty patients (73%) completed 1-year follow-up. Patients in the progressive resistance training group participated in average 11 of 16 training sessions. Leg extension power increased from baseline to 10-week follow-up in progressive resistance training group (progressive resistance training: 0.28 W/kg, P= 0.01, control group: 0.01 W/kg, P=0.93) with no between-group difference. Walking speed and KOOS scores increased from baseline to 10-week follow-up in both groups with no between-group difference (six minutes walk test P=0.63, KOOS P>0.29). Progressive resistance training two days/week combined with home based exercise five days/week was not superior to home based exercise seven days/week in improving leg extension power of the operated leg.

    Full Text Available Objective – To discover public library clients’ needs and preferences for modes of training on the use of the Internet and the libraries’ online resources and to apply these findings to improve training offered by public library staff.Design – Multiple exploratory case study.Setting – Two public libraries in New South Wales, Australia: a regional library (Mudgee Branch of the Mid-Western Regional Council Library Service and a metropolitan library (Marrickville Central Library.Subjects – A total of 24 public library clients. The participants were split evenly between the two libraries, with 12 from the Mudgee Branch and 12 from the Marrickville Central. The respondents were further subdivided into two groups based on age (35 to 44 years old and 65 or older and evenly distributed by sex within the groups.Methods – This study used naturalistic inquiry to frame the multiple exploratory case study of two public libraries. Ruthven used maximum variation sampling to guide the selection of participants. Library staff helped the researcher to identify possible participants at Marrickville, while the researcher advertised for participants at Mudgee Library and at an Internet/database course taught at the Mudgee Business Enterprise Centre. She used snowball sampling to find additional participants at both sites. Ruthven conducted semi-structured interviews with the participants, with questions covering their preferences, recommendations, and needs for online resource training. The data from the interviews and search logs were analyzed using inductive data analysis.Main Results – Participants preferred small group, face-to-face, formalized instruction for initial training on online resources. For further training, participants preferred individualized assistance and immediate support instead of formal classes. They noted a lack of training opportunities and a lack of help from library staff as sources of frustration when trying to learn to

    We have succeeded in increasing up to 150 K the Curie temperature in the Fe{sub 64}N{sub 36}6 invar alloy by means of a severe mechanical treatment followed by a heating up to 1073 K. The invar behavior is still present as revealed by the combination of magnetic measurements with neutron and x-ray techniques under extreme conditions, such as high temperature and high pressure. The proposed explanation is based in a selective induced microstrain around the Fe atoms, which causes a slight increase in the Fe-Fe interatomic distances, thus reinforcing ferromagnetic interactions due to the strong magnetoelastic coupling in these invar compounds.

    A series of Ba1-x-ySrxCayTiO3 compounds were prepared with varying average ionic radii and cation disorder on A-site. All samples showed typical ferroelectric behavior. A simple empirical equation correlated Curie temperature, TC, with the values of ionic radii of A-site cations. This correlation was related to the distortion of TiO6 octahedra observed during neutron diffraction studies. The equation was used for the selection of compounds with predetermined values of TC. The effects of A-site ionic radii on the temperatures of phase transitions in Ba1-x-ySrxCayTiO3 were discussed.

    There has been great interest in using working memory (WM) training regimens as an alternative treatment for ADHD, but it has recently been concluded that existing training regimens may not be optimally designed because they target the primary memory component but not the secondary component of WM capacity. This conclusion requires the ability to accurately measure changes in primary and secondary memory abilities over time. The immediate free recall task has been used in previous studies to measure these changes; however, one concern with these tasks is that the recall order required on training exercises may influence the recall strategy used during free recall, which may in turn influence the relative number of items recalled from primary and secondary memory. To address this issue, previous training studies have explicitly controlled recall strategy before and after training. However, the necessity of controlling for recall strategies has not been explicitly tested. The present study investigated the effects of forward-serial-order training on free recall performance under conditions in which recall strategy was not controlled using a sample of adolescents with ADHD. Unlike when recall order was controlled, the main findings showed selective improvement of the secondary memory component (as opposed to the primary memory component) when recall order was uncontrolled. This finding advances our understanding of WM training by highlighting the importance of controlling for recall strategies when free recall tasks are used to measure changes in the primary and secondary components of WM across time.

    To design and implement a teaching skills curriculum that addressed the needs of an ophthalmology residency training program, to assess the effect of the curriculum, and to present important lessons learned. A teaching skills curriculum was designed for the Harvard Medical School (HMS) Residency Training Program in Ophthalmology. Results of a needs assessment survey were used to guide curriculum objectives. Overall, 3 teaching workshops were conducted between October 2012 and March 2013 that addressed areas of need, including procedural teaching. A postcurriculum survey was used to assess the effect of the curriculum. Massachusetts Eye and Ear Infirmary, a tertiary care institution in Boston, MA. Overall, 24 residents in the HMS Residency Training Program in Ophthalmology were included. The needs assessment survey demonstrated that although most residents anticipated that teaching would be important in their future career, only one-third had prior formal training in teaching. All residents reported they found the teaching workshops to be either very or extremely useful. All residents reported they would like further training in teaching, with most residents requesting additional training in best procedural teaching practices for future sessions. The pilot year of the resident-as-teacher curriculum for the HMS Residency Training Program in Ophthalmology demonstrated a need for this curriculum and was perceived as beneficial by the residents, who reported increased comfort in their teaching skills after attending the workshops.

    2016-11-01

    The present work aims to estimate the Curie point depth and the surface heat flow for the northern part of the Western Desert using aeromagnetic data. Applying spectral analysis to aeromagnetic anomalies has provided equitable promising geological results, useful for further geothermal or petroleum exploration. The total intensity aeromagnetic map was first reduced to the north magnetic pole to correct the shape and position of different magnetic anomalies over their causative bodies. Secondly, the short wavelengths were removed to enhance the deeper long wavelengths related to the deep sources. Spectral analysis indicates that the area is underlined by an average Curie point depth of about 27 km. This implies an average thermal heat flow (53 mW/m2) lower than the average global heat flow. The investigated area was divided into eighteen blocks, where the average depths to centroid and top of the magnetic source were estimated for each block. The results of this work show a general depth increase of the magnetic boundaries from 24.5 km in the southern area to 33 km at the northern part. The calculated surface heat flow decreases from about 56 to 42 mW/m2 in the same direction. Consequently, this area is characterized by its low geothermal gradient and surface heat flow. This low geothermal gradient indicates that the upper mantle contributes to the magnetic features at the northern offshore parts. This work also recommends by deep drilling for petroleum exploration and production within the Egyptian Mediterranean Sea exploration strip.

    The Curie temperatures and spin reorientation temperatures of a series of four melt-spun nanocomposite materials comprised of Nd{sub 2}Fe{sub 1}4B and varying amounts of {alpha}-Fe were measured using independent techniques. The phase constitution and grain size was assessed with synchrotron x-ray diffraction; the Curie temperatures were measured by differential thermal analysis (DTA) and dc SQUID magnetometry in the temperature range 375 K {le} T {le} 800 K, whereas the spin reorientation transition temperature was determined from ac susceptibility measurements taken in the range 10 K {le} T {le} 300 K. The Curie temperature increases with increasing excess iron content, resulting in a 18 {degree} enhancement over the Curie temperature of pure Nd{sub 2}Fe{sub 14}B for 27 wt% excess {alpha}-Fe. The spin reorientation temperatures are depressed from the single-crystal value by an average of 10 degrees. Both anomalous effects are attributed to intergranular exchange coupling present in the alloys, although the effects of uncompensated stress between the constituent phases cannot be ruled out The experimental results suggest that while the Curie temperature of the Nd{sub 2}Fe{sub 14}B phase may be extrinsically enhanced significantly beyond the bulk value, possibly extending the range of applications of this compound, the anisotropy may be simultaneously lowered, impeding the attainment of high coercivities in these alloys.

    Based on a cohort of 150 patients treated by curie-therapy for a prostate cancer, the authors report the analysis of the influence of some technical modifications (use of an automatic stepper at the beginning of a second period, and of a high frequency echographic probe during a third period) on the urinary toxicity. This toxicity has been assessed by using the urinary retention rate, and the difference between the maximum and initial International Prostate Symptom Score (IPPS). Rectal morbidity has been scaled according to a modified Radiation Therapy Oncology Group (RTOG) scale. It appears that the occurrence of urinary retention after prostate radiotherapy decreases with practice and use of the automatic stepper. It seems that there is no impact on urinary morbidity (urinary retention excluded) nor on rectal morbidity. Short communication

    This study develops and solves two-dimensional convective-conductive coupled partial differential equations based on Pennes' bio-heat transfer model using low Curie temperature nanoparticles (LCTNPs) to illustrate thermal behavior quantitatively within tumor-normal composite tissue by establishing a multi-region finite difference algorithm. The model combines NEel relaxation and temperature-variant saturation magnetization derived from Brillouin Equation and Curie-Weiss Law. The numerical results indicate that different deposition patterns of LCTNP and boundary conditions directly effect the steady state temperature distribution. Compared with high Curie temperature nanoparticles (HCTNPs), optimized distributions of LCTNPs within tumorous tissue can be used to control the temperature increase in tumors for hyperthermia treatment using an external magnetic field while healthy tissue surrounding a tumor can be kept closer to normal body tissue, reducing the side effects observed in whole body and regional hyperthermia therapy.

    The (15)N-HSQC spectra of low-spin cyano-met-myoglobin and high-spin fluoro-met-myoglobin were assigned and dipole-dipole-Curie-spin cross-correlated relaxation rates measured. These cross-correlation rates originating from the dipolar (1)H-(15)N interaction and the dipolar interaction between the (1)H and the Curie spin of the paramagnetic center contain long-range angular information about the orientation of the (1)H-(15)N bond with respect to the iron-(1)H vector, with information measurable up to 11 A from the metal for the low-spin complex, and between 10 to 25 A for the high-spin complex. Comparison of the experimental data with predictions from crystal structure data showed that the anisotropy of the magnetic susceptibility tensor in low spin cyano-met-myoglobin significantly influences the cross-correlated dipole-dipole-Curie-spin relaxation rates.

    Ferromagnetic–paramagnetic phase transitions in classical and quantum thin films have been studied up to 50 mono-layers using effective field theory with two-site cluster approximation. Variation of the Curie temperature as a function of film thickness has been examined. The relative shift of the Curie temperature from the corresponding bulk value has been investigated in terms of the shift exponent λ. We have found that shift exponent λ clearly depends on the strength of the ferromagnetic exchange coupling of the surface. Moreover, we have not observed any significant difference between classical and quantum exponents for a particular model.

    Structural and magnetic changes on invar Fe{sub 64}Ni{sub 36} alloy (T{sub C}=500 K) produced by mechanical milling followed by heating up to 1073 K, were investigated by neutron diffraction, magnetization measurements, X-ray diffraction under high pressures and X-ray absorption at both Fe and Ni K-edges. We argue that the strain induced in the Fe{sub 64}Ni{sub 36} material after this treatment mainly affects the Fe sites due to the magnetovolume coupling, the most notorious feature being the increase of the Curie temperature ({delta}T{sub C}=70 K).

  19. The study of high Curie temperature ferromagnetism properties in Mn-doped SiC thin film

    Directory of Open Access Journals (Sweden)

    Chaoyang Kang

    2015-01-01

    Full Text Available Mn-doped 3C-SiC film has been prepared onto the Si (111 substrate by employing a molecular beam epitaxy method. The experimental analysis establishes that the prepared sample shows the ferromagnetic property with a relatively high Curie temperature (Tc of 355 K, which is an exciting phenomenon on account of the scarceness in the SiC-based diluted magnetic semiconductor. The analysis derived from the X-ray diffraction and absorption spectroscopy patterns indicates that Mn atoms should react with Si atoms and then form Mn4Si7 compounds. Combined with the theoretical simulation, it is speculated that a new alloy phase of Mn4Si7Cx maybe appear, which should be responsible for the exceptionally high Tc ferromagnetic behavior in the sample.

    Mn1-xAlxCoGe alloys with a second order transition were produced by arc-melting method. The substitution of Mn by Al increased the Curie temperature (TC) from 260.5 K to 300.8 K, the magnetic entropy change (|ΔSM|) decreased from 3.78 J·Kg-1K-1 to 2.35 J·Kg-1K-1 under a field change of Δμ0H=5 T. In addition, the |ΔSM| well linearly depends on the H2/3 around TC. Furthermore, the relative cooling power (RCP) can reach 242.3 J·Kg-1 with a large full width at half maximum of |ΔSM| (75.5 K) for x=0.02. The decrease of |ΔSM| is explained by the corresponding monotonical decrease of magnetic moment per formula unit.

    We demonstrate by magneto-transport measurements that a Curie temperature as high as 200 K can be obtained in nanostructures of (Ga,Mn)As. Heavily Mn-doped (Ga,Mn)As films were patterned into nanowires and then subject to low-temperature annealing. Resistance and Hall effect measurements demonstrated a consistent increase of T(C) with decreasing wire width down to about 300 nm. This observation is attributed primarily to the increase of the free surface in the narrower wires, which allows the Mn interstitials to diffuse out at the sidewalls, thus enhancing the efficiency of annealing. These results may provide useful information on optimal structures for (Ga,Mn)As-based nanospintronic devices operational at relatively high temperatures.

    The effects of heavy rare earth (RE) additions on the Curie temperature (TC) and magnetocaloric effect of the Fe-RE-B-Nb (RE = Gd, Dy and Ho) bulk metallic glasses were studied. The type of dopping RE element and its concentration can easily tune TC in a large temperature range of 120 K without significantly decreasing the magnetic entropy change (ΔSM) and refrigerant capacity (RC) of the alloys. The observed values of ΔSM and RC of these alloys compare favorably with those of recently reported Fe-based metallic glasses with enhanced RC compared to Gd5Ge1.9Si2Fe0.1. The tunable TC and large glass-forming ability of these RE doped Fe-based bulk metallic glasses can be used in a wide temperature range with the final required shapes.

    The structural and magnetic properties of Mn{sub 5}Ge{sub 3}C{sub x} films prepared at elevated substrate temperatures T{sub S} are investigated. In particular, films with x{>=}0.5 and T{sub S}=680 K exhibit a strongly enhanced Curie temperature T{sub C}=445 K compared to bulk Mn{sub 5}Ge{sub 3} with T{sub C}=304 K while at the same time the average Mn moment decreases from 2.6 to 1 {mu}{sub B}. Structural analysis of these films suggests that the carbon is interstitially incorporated into the voids of Mn octahedra of the hexagonal Mn{sub 5}Si{sub 3}-type structure giving rise to a lattice compression. The enhanced ferromagnetic stability in connection with the lattice compression is interpreted in terms of an Mn-Mn interaction mediated by C based on a change in the electronic structure.

    This article examines the poetic contribution of Valerie Gillies, Edinburgh Makar (or poet of the city) from 2005-2008, to the Edinburgh Marie Curie Hospice Quiet Room, a new contemplation space for patients, families, and staff. In collaboration with others, Gillies created a transitional space for the Quiet Room, centered on the display of her sonnet, "A Place Apart." This space functions to comfort visitors to the Quiet Room by relocating them in their surroundings and offering the solace provided by nature and history. With this project, her first as Edinburgh Makar, Gillies redefines the role of the poet as healer and advocates for newer forms of palliative care that focus on patients' spiritual and emotional, as well as physical, wellbeing.

    We present the electronic structures, magnetic exchange interactions and Curie temperature (T{sub C}) of GaMnN and GaMnAs calculated by self-interaction-corrected local-density approximation (LDA-SIC). In GaMnAs, the LDA-SIC results of T{sub C} do not differ so much from the LDA results. Both the LDA and LDA-SIC values are in a good agreement with the experimental data. In GaMnN, on the other hand, the ferromagnetic exchange interactions are enhanced due to the suppression of antiferromagnetic super-exchange interaction, resulting in T{sub C} higher than the LDA results.

    GMES Initial Operations - Network for Earth Observation Research Training (GIONET) is a Marie Curie funded project that aims to establish the first of a kind European Centre of Excellence for Earth Observation Research Training. GIONET is a partnership of leading Universities, research institutes and private companies from across Europe aiming to cultivate a community of early stage researchers in the areas of optical and radar remote sensing skilled for the emerging GMES land monitoring services during the GMES Initial Operations period (2011-2013) and beyond. GIONET is expected to satisfy the demand for highly skilled researchers and provide personnel for operational phase of the GMES and monitoring and emergency services. It will achieve this by: * Providing postgraduate training in Earth Observation Science that exposes students to different research disciplines and complementary skills, providing work experiences in the private and academic sectors, and leading to a recognized qualification (Doctorate). * Enabling access to first class training in both fundamental and applied research skills to early-stage researchers at world-class academic centres and market leaders in the private sector. * Building on the experience from previous GMES research and development projects in the land monitoring and emergency information services. * Developing a collaborative training network, through the placement of researchers for short periods in other GIONET organizations. Reliable, thorough and up-to-date environmental information is essential for understanding climate change the impacts it has on people's lives and ways to adapt to them. The GIONET researchers are being trained to understand the complex physical processes that determine how electromagnetic radiation interacts with the atmosphere and the land surface ultimately form the signal received by a satellite. In order to achieve this, the researchers have been placed in industry and universities across Europe, as

    Purpose Given the scarcity of malignant phyllode tumours of the breast and the absence of consensus regarding their management justify the need for institutional retrospective evaluations of clinical practices. Patients and methods Retrospective study with central pathology review of the 25 consecutive patients treated at the Institut Curie (Paris, France) between 1969 and 2006 for non metastatic malignant phyllodes tumors of the breast. The median follow-up was 65 months (7-257 months). Results Median age at diagnosis was 52 years (20-64 years). Breast surgery was conservative in five patients (20%). Surgical margins were wide (> 10 mm), narrow, involved or unknown in respectively 17 (68%), three (12%), three (12%) and two (8%) patients. Median tumour size was 65 mm (12-250 mm). Adjuvant radiotherapy was delivered in seven (28%) patients (two patients, post tumor-ectomy; five patients, post mastectomy) and 13 patients (52%) received anthracycline-based adjuvant chemotherapy. Five-year overall survival rate was 91% (95% CI, 80-100%). Five patients (20%) developed distant metastases (one after chemotherapy) and three (12%) locoregional relapse (one after tumor-ectomy and unknown margin without radiotherapy, two after mastectomy and involved margins with radiotherapy). Conclusion Wide breast surgery (that can be conservative in selected patients) is the mainstay of the treatment of non metastatic malignant phyllodes tumors of the breast. To better determine the respective roles of adjuvant systemic treatment and radiotherapy, further clinical studies and the search for new prognostic and predictive factors remain necessary.

Its operation involves the use of magnetocaloric effect (MCE) of a magnetic material caused by application of magnetic field. Manganite-based material demonstrates maximum MCE at its magnetic ordering temperature known as Curie temperature (TC). Consequently, manganite-based material with TC around room temperature is essentially desired for effective utilization of this technology. The TC of manganite-based materials can be adequately altered to a desired value through doping with appropriate foreign materials. In order to determine a manganite with TC around room temperature and to circumvent experimental challenges therein, this work proposes a model that can effectively estimates the TC of manganite-based material doped with different materials with the aid of support vector regression (SVR) hybridized with gravitational search algorithm (GSA). Implementation of GSA algorithm ensures optimum selection of SVR hyper-parameters for improved performance of the developed model using lattice distortions as the descriptors. The result of the developed model is promising and agrees excellently with the experimental results. The outstanding estimates of the proposed model suggest its potential in promoting room temperature magnetic refrigeration through quick estimation of the effect of dopants on TC so as to obtain manganite that works well around the room temperature.

  17. CIENTISTAS EM REVISTA: EINSTEIN, DARWIN E MARIE CURIE NA CIÊNCIA HOJE DAS CRIANÇAS

    Sheila Alves de Almeida

    Full Text Available RESUMO: Este trabalho analisou três edições da revista Ciência Hoje das Crianças, em que Einstein, Darwin e Marie Curie são apresentados. Frente ao desafio de divulgar a vida e a obra desses cientistas de forma adequada às crianças, para análise dos artigos consideramos a linguagem utilizada, as imagens apresentadas e, principalmente, a representação da revista sobre os cientistas. A metodologia de análise do material é inspirada nos trabalhos de Bakhtin sobre dialogismo e na compreensão por meio dos procedimentos discursivos, verbais e visuais com que a revista interpela e dialoga com as crianças. Os resultados mostram que a chancela editorial opta por focar a infância dos cientistas e uma imagem do cientista curioso e aventureiro. Entretanto, veicula-se nos artigos analisados uma visão estereotipada do cientista como alguém que já se anunciava cientista. Reitera-se a importância da Ciência Hoje das Crianças para a promoção da leitura e a democratização da linguagem de divulgação científica para crianças.

    Purpose: To evaluate the treatment results of patients (pts) with Figo stage IB2, IIA, IIB cervical carcinoma (C.C.) treated with preoperative radio chemotherapy, followed by extended radical hysterectomy. Patients and methods: Retrospective study of 148 women treated to the Curie Institute for operable Figo Stage IB2 to IIB, biopsy proved C.C.. Among them, 70 pts, median age 46 years, were treated using the same regimen associating primary radio cis-platinum based chemotherapy,intracavitary LDR brachytherapy, followed by extended radical hysterectomy. Kaplan-Meier estimates were used to draw survival curves. Comparisons of survival distribution were assessed by the log-rank test. Results: Complete histological local-regional response was obtained in 56% of the pts (n = 39). Residual macroscopic or microscopic disease in the cervix was observed in 28 pts (40%). All but one had in situ microscopic residual C.C.. Lateral residual disease in the parametria was also present in nine pts, all with residual C.C.. Pelvic lymph nodes were free from microscopic disease in 56 pts (80%). Eight of 55 (11%) radiological N0 patients had microscopic nodal involvement, as compared to 6/15 (40%) radiological N1 (p = 0.03). Seventeen pts (25%) had residual cervix disease but negative nodes. After median follow-up of 40 months (range, 8-141), 38/70 patients (54.1%) are still alive and free of disease, six (8.6%) alive with disease, and 11 (15.8%) patients were lost for follow-up but free of disease. Conclusion: The treatment of locally advanced C.C. needs a new multidisciplinary diagnostic and treatment approach using new therapeutic arms to improve the survival and treatment tolerance among women presenting this disease.

    2009-05-01

    Positive reinforcement training (PRT) efficiency was examined as a function of training frequency in 33 pair- or triple-housed female rhesus macaques. The animals were trained three times a week, once a day or twice a day, using PRT and a clicker as a secondary reinforcer. All animals were trained on 30 sessions, with an average of 5 min per training session per animal. The behaviors, trained in succession, were Targeting (reliably touching and following a Target); Collaborating (dominant animals allowing subordinates to train while stationing); Box-training (accepting being enclosed in a small compartment while responding to Target training) and initial Injection training.Fulfilled criteria for Targeting were obtained in 32/33 animals in a median of nine training sessions. Collaboration was obtained in 27/33 animals in a median of 15 training sessions. However, only four animals completed Box-training during the 30 training sessions and started Injection training. When comparing training success in terms of number of training sessions, training twice a day was less efficient than the other two treatments. In terms of daily progress, our results suggest that from a management perspective, daily training is more conducive to quick training success than thrice weekly training. In addition, in this study no further advantages could be gained from training twice a day.

  4. Estimating the Curie point depth using aeromagnetic data with a fractal model in the Province of Québec, eastern Canada

    New technologies that allow geothermal energy production in colder conditions result in interest for geothermal exploration in low heat flux regions that were previously overlooked. The Province of Québec, eastern Canada, is such a case. It is a large and cold area with a low amount of heat flux measurements, and mapping the Curie point depth is appealing as an exploration tool due to the scarcity of the direct data. For that purpose, we have revisited a methodology to estimate the Curie point depth using a fractal source distribution model and aeromagnetic data. Our methodology relies on a statistical model of crustal magnetization having a constant magnetization direction and random magnetization amplitude. The shape of the radial average of the logarithm of the power spectrum of magnetic anomalies is predicted using this model. The model parameters (thickness and depth to the top of the magnetic layer, the fractal exponent β and the constant C') are obtained by calculating the best fit between the theoretical and observed radial power spectra using a non-linear least-square algorithm. Rather than using a constant value for the fractal exponent β over the whole study area, which would overcorrect the shape of the radially averaged power spectra in some zones, we propose a new calibration workflow based on heat flux measurements and lithology. This workflow includes the use of sequential Gaussian simulations (SGS) of heat flux data to enlarge the limited available dataset. The use of SGS also allows quantifying the uncertainty and the range of the predicted Curie point depths. This work contributes to mapping the Curie point depth at large scale and help identifying potential areas for further detailed exploration programs and potential geothermal energy production in the Province of Québec.

The solid solutions show a single phase perovskite structure, and the content of BiCoO3 has a significant effect on the microstructure of ceramics. The BFC-BTx ceramics exhibit improved Curie temperature Tc, together with increased piezoelectric properties. In particular, x=0.6% BFC-BTx ceramics, with a Curie temperature, Tc, of ∼488 °C, show optimum piezoelectric properties of d33=167 pC/N, kp=0.32. The combination of good piezoelectric properties and high Tc makes these ceramics suitable for elevated temperature piezoelectric devices.

  8. Engineering of the Curie temperature of epitaxial Sr1-xBaxTiO3 films via strain

    The impact of strain on the structural and electrical properties of epitaxial Sr1-xBaxTiO3 films grown on single crystalline DyScO3 (110), TbScO3 (110), and GdScO3 (110) substrates is presented. X-ray diffraction measurements demonstrate that all films are grown epitaxially. The tensile in-plane strain is only partially compensated by a contraction of the out-of-plane lattice parameter. As a result, the volume of the unit cell of the Sr1-xBaxTiO3 film increases due to the tensile strain, and the resulting Poisson ratio of the film is ν ≈ 0.33, which is larger than but still close to the literature values of ν ≈ 0.23 for unstrained defect-free SrTiO3. The Curie temperature derived from the temperature dependence of the in-plane dielectric response leads to a strain-temperature phase diagram for the epitaxial Sr1-xBaxTiO3 films. The experimental data show a deviation from the linear dependence predicted by the Landau thermodynamic theory for large strain (>1.2%). However, using the equilibrium thermodynamic analysis, we can demonstrate that this deviation arises from the relaxation of the strain due to defect formation in the film. The result reveals that in addition to the nominal misfit strain, the defect formation strongly affects the effective strain and, thus, the dielectric response of epitaxially grown ferroelectric films.

    The critical diffusion of neutrons in iron is due to the magnetisation fluctuations which occur in ferromagnetic substances in the neighbourhood of the Curie temperature. The fluctuations can be described in correlation terms; a correlation function {gamma}{sub R{sub vector}} (t) is defined, {gamma}{sub R{sub vector}} (t) = mean value of the scalar product of a reference spin and a spin situated at a distance (R) from the first and considered at the instant t. In chapter I we recall the generalities on neutron diffusion cross-sections; a brief summary is given of the theory of VAN HOVE, who has shown that the magnetic diffusion cross section of neutrons is the Fourier transformation of the correlation function. In chapter Il we study the spatial dependence of the correlation function, assumed to be independent of time. It can then be characterised by two parameters K{sub 1} and r{sub 1}, by means of which the range and intensity of the correlations can be calculated respectively. After setting out the principle of the measurement of these parameters, we shall describe the experimental apparatus. The experimental values obtained are in good agreement with the calculations, and the agreement is better if it is supposed that the second and not the first neighbours of an iron atom are magnetically active, as proposed by Neel. In chapter III we study the evolution with time of the correlation function; this evolution is characterised by a parameter {lambda} depending on the temperature, which occurs in the diffusion equation obeyed by the magnetisation fluctuations: {delta}M{sub vector}/{delta}t = {lambda} {nabla}{sup 2} M{sub vector}. The principle of the measurement of {lambda} is given, after which the modifications carried out on the experimental apparatus mentioned in chapter II are described. The results obtained are then discussed and compared with the theoretical forecasts of De Gennes, mode by using the

Focaliza as percepções de graduandos em relação à participação em um projeto de extensão que lhes possibilitou atuar como professores de alunos em sala de aula da Educação de Jovens e Adultos (EJA, durante um ano letivo. Foram realizadas entrevistas semi-estruturadas com nove participantes. O conteúdo das falas foi analisado e organizado em quatro categorias temáticas.

Our GeMn layers grown at low temperature (70 C to 130 C) are composed of vertical Mn-rich nano-columns. Samples grown at temperatures higher than 130 C contain GeMn nanoclusters.

  3. Exchange coupling and magnetoresistance in CoFe/NiCu/CoFe spin valves near the Curie point of the spacer

    Andersson, S.; Korenivski, V.

    2010-05-01

    Thermal control of exchange coupling between two strongly ferromagnetic layers through a weakly ferromagnetic Ni-Cu spacer and the associated magnetoresistance is investigated. The spacer, having a Curie point slightly above room temperature, can be cycled between its paramagnetic and ferromagnetic states by varying the temperature externally or using joule heating. It is shown that the giant magnetoresistance vanishes due to a strong reduction in the mean free path in the spacer at above ˜30% Ni concentration—before the onset of ferromagnetism. Finally, a device is proposed which combines thermally controlled exchange coupling and large magnetoresistance by separating the switching and the readout elements.

    Full Text Available Curie temperature (TC of anatase Co-doped TiO2 epitaxial thin films was systematically investigated as functions of carrier density (n and Co content (x by electrical transport and magnetization measurements at low temperature regime. The estimated TC from both measurements showed similar TC. For x = 0.03, 0.05, and 0.07, non-monotonic TC vs. n relations were observed, whereas TC was monotonically increasing function of n for x = 0.10. Possible mechanism of high TC ferromagnetism for this compound was discussed.

    Discussions were given on effects of acid pretreatment and tetralin swelling in Wandoan coal on a Curie point flash pyrolysis (which used a Curie point pyrolyzer). Residue yield loss effects were obtained at 3.9% in hydrochloric acid pretreatment, and 6.2% in acetic acid pretreatment. The effects of tetralin swelling pretreatment were compared in the similar manner in terms of the residue yield loss. The effects were 4.0% in untreated coal, 2.0% in the hydrochloric acid pretreatment, and 0.6% in the acetic acid pretreatment. It is thought that components that can be activated by acetic acid have already been activated, but the remaining components would not be activated by tetralin. Average microporosity (area) in the remaining particle as a whole shows very little difference both in acetic acid pretreated coal and untreated coal. However, with the acetic acid pretreatment, pores smaller than 4{mu}m{sup 2} disappeared, and pores as large as 205 to 411{mu}m{sup 2} increased largely. This phenomenon was observed as an increase in foaming degree under microscopic observation, even if the average microporosity remains equal. Thermoplasticity of the coal increased, and so did volatilization reactivity as a result of the acetic acid pretreatment, resulting in appearance of a large number of large pores. 6 refs., 2 figs., 2 tabs.

  12. DFT+ U study of electronic structure and Curie temperature of A2 B ReO6 (A=Sr, Ca and B=Cr, Fe)

    Science.gov (United States)

    Lee, Alex; Marianetti, Chris

    Re-based double perovskites (DPs) have attracted much attention due to their high Curie temperature (TC) and colossal magneto resistance with large potential for spintronic applications. Here we investigate the electronic and magnetic properties of the Re-based DPs A2 B ReO6 (A=Sr, Ca and B=Cr, Fe) using density functional theory + U (DFT+ U) calculations. While monoclinic Ca2CrReO6 and Ca2FeReO6 (monoclinic) are insulating within GGA+ U, tetragonal Sr2CrReO6 (a0a0c0) and Sr2FeReO6 (a0a0c-) remain metallic. We show that both on-site interaction U and octahedral tilting are critical to obtain the insulating phases. The a0a0c- -phase of Sr2CrReO6 is most stable and insulating with nonzero U, suggesting that the high quality Sr2CrReO6 film on STO substrate can be a semiconductor as reported in recent experiments. We explain that the insulator-to-metal transition (MIT) of Ca2FeReO6 at 140K is predominantly due to a structural phase transition which drives the insulating state. Curie temperatures of Re-based DPs are calculated using the classical Monte Carlo simulations based on the Heisenberg model.

    2016-09-01

    We present an innovative study to generalize Curie Point Depth (CPD) determinations at the scale of oceanic volcanic islands, an approach which has previously focused largely on continental areas. In order to determine the validity of this technique in oceanic environments, we first tested the approach on sets of sea-floor-spreading anomalies. Assuming that magnetic anomalies are concentrated within the oceanic crust and uppermost mantle, the Curie depth should deepen as oceanic lithosphere increases in age and thickness away from spreading centers. The calculated depths to the magnetic bottom are in agreement with this general pattern. On the basis of this test, we then applied the method to La Réunion Island and surrounding oceanic lithosphere. The calculated extent of magnetic sources lies at depths between 10 and 30 km and exhibits a complex topography, presumably caused by a combination of various magmatic and tectonic lithospheric structures. These calculations indicate that magnetic sources extend well below the crust-mantle interface at this location. To the first order, the bottom of the magnetic surface shallows beneath Réunion and Mauritius Islands due to the thermal effect of the hot spot, and deepens away from La Réunion edifice. On the scale of the Mascarene Basin, several discontinuities in the CPD correlate well with major fracture zones.

    NaZn13型La(Fe,Si)13化合物随Si含量增加,相变性质由一级过渡为二级,化合物晶胞体积收缩,饱和磁化强度降低,居里温度升高。其居里温度与晶胞体积之间的关系不能用Bethe-Slater曲线给出合理的解释。本文利用添加间隙原子碳调节La(Fe,Si)13化合物晶胞体积和居里温度的方法,系统研究了该化合物居里温度与晶胞体积之间的关系。结果发现二者之间的变化规律遵循Jaccarino-Walker模型,即仅有5%甚至更少的3d电子被认为是真正的巡游电子,其余的3d电子仍是局域的。以极化的巡游电子为媒介,局域电子之间产生类似于Ruderman-Kittel-Kasuya-Yosida 的长程相互作用,相互作用的符号和大小与距离呈周期性震荡。随Si含量的增加, La(Fe,Si)13化合物巡游电子数目增加,化合物的居里温度由晶胞体积和巡游电子的浓度共同决定。%In NaZn13 type La(Fe,Si)13 compound, the phase transition nature varies from the first order to the second order, the cell volume contracts, the saturated magnetization decreases and the Curie temperature increases with increasing Si content. In this paper, the relation between the Curie temperature and the cell volume is investigated systematically by introducing the interstitial carbon atoms, which is an efficient method to control the cell volume and the Curie temperature. It is found that the relation between the Curie temperature and the cell volume is consistent with the Jaccarino-Walker model, in which only 5% or less 3d electrons are considered as the itinerant electrons and the others are regarded as the localized ones. With the polarized itinerant electrons used as a medium, the interaction between the 3d localized electrons is similar to Ruderman-Kittel-Kasuya-Yosida interaction, whose sign and magnitude oscillate periodically with distance. The number of the itinerant electrons of the La (Fe,Si)13 increases with the increase of Si content. The Curie

    Searching low sintering temperature material with ultra-high Curie temperature (>800 °C) is urgent to seafloor hydrothermal vents detection. Bi2WO6, as the simplest member of the Aurivillius family was improved to possess ultra-high Curie temperature and ultra-high depolarization temperature by experiment at first time. The crystal structure was determined by ab initio and Rietveld refinement calculations. The symmetry group of ultra-high Curie temperature Bi2WO6 is Aba2 (41). The Curie temperatures of Bi2(1-x)La2xWO6 (x = 0, 0.005, 0.01, 0.02, 0.04) with increasing x are 952 °C, 1008 °C, 905 °C, 853 °C, 822 °C, respectively, and depolarization temperatures of them are around 915 °C, 905 °C, 880 °C, 800 °C, and 725 °C, respectively. The typical properties are as follows: Curie temperature T c = 905 °C, depolarization temperature T d = 880 °C, mechanical quality factor Q m = 621.8, d 33 = 17 pC/N, K 33 = 82.01, tanδ = 0.19 × 10-2 with x value of 0.01.

    The Mission Operations Lab initiated a project to design, develop, deliver, test, and validate a unique training system for astronaut and ground support personnel. In an effort to keep training costs low, virtual training units (VTUs) have been designed based on images of actual hardware and manipulated by a touch screen style interface for ground support personnel training. This project helped modernized the training system and materials by integrating them with mobile devices for training when operators or crew are unavailable to physically train in the facility. This project also tested the concept of a handheld remote device to control integrated trainers using International Space Station (ISS) training simulators as a platform. The portable VTU can interface with the full-sized VTU, allowing a trainer co-located with a trainee to remotely manipulate a VTU and evaluate a trainee's response. This project helped determine if it is useful, cost effective, and beneficial for the instructor to have a portable handheld device to control the behavior of the models during training. This project has advanced NASA Marshall Space Flight Center's (MSFC's) VTU capabilities with modern and relevant technology to support space flight training needs of today and tomorrow.

    Full Text Available It is the basic requirement of maritime safety education to guarantee the safety of teaching operation while training the crew's occupation safety capability. Marine Training Center of Shanghai Maritime University has undertaken the practical teaching of "marine survival" for many years and come up with the whole safety procedures of training. Based on the requirements of SOLAS convention and regulations of STCW over crew training, this paper introduces the safety allocation, utilization and maintenance of teaching equipments. Through the investigation of the safety situation of students' practical operation, the safety teaching method named "four in one" has been put forward, which includes the pre-teaching safety precaution, the whole monitor during the teaching process, the post-teaching summary evaluation, and the reset and standby of teaching facilities. Finally, during the learning and training of "marine survival", crews and students are called on to place priority on personal safety rather than acquisition of knowledge and skills. Only in this way can they be capable of self-protection and protection of others in the career of seafaring.

    The World Health Organization and the National guidelines on infant and young child feeding recommend the practice of exclusive breastfeeding of infants for the first 6 months after their birth. The objective of this study was to estimate the prevalence of the early initiation of and exclusive breast feeding. A cross sectional, descriptive study was done. 79 infants and children who attended the under five clinic in the Rural Health Training Centre (RHTC), Pulipakkam Village, were chosen for the study by convenient sampling. This study was conducted by interviewing 79 mothers of the children in the ages of 0-24 months, who attended the under five clinic of RHTC, Pulipakkam. The data was collected by using a pre tested, structured questionnaire to obtain the information on the breast feeding and the hygienic feeding practices among mothers. The statistical analysis was done by the authors by using the SPSS, version 16. The significance in the differences were evaluated by using the Chi square test and the relationship between the variables were evaluated by using Kendall's tau correlation. A p value of practices among the mothers were significantly associated with an increased incidence of upper and lower respiratory tract infections and gastro intestinal infections in the infants and the children. The education of the antenatal mothers on the benefits of breast feeding and hygienic feeding practices and making all hospitals baby friendly have to be focused on, in order to achieve 80% exclusive breast feeding as per the national guidelines on infant and young child feeding. We need to strengthen the MCH services in the study area in order to achieve 100% immunization.

    Córdoba is a city with 1,300,000 inhabitants located in the center of Argentina. Although Palliative Medicine is a discipline that has been present for a little over 10 years, it has not developed in step with demand, owing to lack of political will and insufficient support from the Health Administration. However, the existing units have expanded, thanks to the efforts of their staff members, who help hundreds of terminally ill patients and their families, provide training at undergraduate and postgraduate university levels, and make information available to the general public through different activities in the community.

Brezin / ENS, Paris, F. The notion of broken symmetries started slowly to emerge in the 19th century. The early studies of Pasteur on the parity asymmetry of life, the studies of Curie on piezoelectricity and on the symmetries of effects versus the symmetry of causes (which clearly excluded spontaneous symmetry breaking), are important historical landmarks. However the possibility of spontaneous symmetry breaking within the usual principles of statistical mechanics, waited for the work of Peierls and Onsager. The whole theory of phase transitions and critical phenomena, as well as the construction of field theoretic models as long distance limit of yet unknown physics, relies nowadays on the concept of criticality associated to spontaneous symmetry breaking.

    We report on the magnetic, magnetotransport and structural characterization of (Ca{sub 1-y}Nd{sub y}){sub 2}Fe{sub 1+x}Mo{sub 1-x}O{sub 6} (x<0.5) ferromagnetic double perovskites. It is found that the presence of an excess (x>0) of Fe ions in the metallic sublattice produces a remarkable increase, by more than 90 K, of the Curie temperature. Moessbauer spectroscopy data indicate a reinforcement of the magnetic interactions. We argue that this dramatic enhancement of the ferromagnetic order is due to the strong antiferromagnetic superexchange coupling between near-neighbour Fe-Fe occupying regular and antisite positions in the structure. Moreover, the results indicate that the excess of magnetic ions (Fe) is essential to overcome the dilution effects caused by antisite defects.

    Structural, magnetic, and transport properties of perovskite La2/3Ca1/3Mn1-xSixO3 (x=0, 0.025, 0.05) have been studied. The incorporation of Si decreases the overall resistivity, but obviously increases the Curie temperature (Tc), metal-insulator transition temperature (Tp), and the magnetoresistance ratio MR (defined as [R(0)-R(H)]/R(O)) near room temperature. Comparing with La2/3Ca1/3MnO3, the Tc, Tp, and MR of the sample with x=0.05 increase by 30, 45K, and 20%, respectively. Lattice effects may play a more important role than the magnetic dilution in the case of low Si substitution.

    After being selected to the astronaut office, crewmembers go through an initial two year training flow, astronaut candidacy, where they learn the basic skills necessary for spaceflight. While the bulk of astronaut candidate training currently centers on the multiple subjects required for ISS operations (EVA skills, Russian language, ISS systems, etc.), training also includes geoscience training designed to train crewmembers in Earth observations, teach astronauts about other planetary systems, and provide field training designed to investigate field operations and boost team skills. This training goes back to Apollo training and has evolved to support ISS operations and future exploration missions.

    This study follows two other ones about the same subject. No one could bring elements to the question of the exposure impact on the population having stayed in the school. The old pupils and personnel have been exposed to radiation doses higher to the limit values of public exposure especially before 1987. The scientific knowledge suggest that the eventual sanitary consequences are in the area of low risks. The lack of exhaustiveness in the inquiry realisation and the lack of statistical power did not allow to measure the sanitary impact of ionizing radiation exposure among the former pupils of the Marie Curie school of Nogent sur Marne.

    Congestion is a major problem in most cities and the problem is growing (Quiroga, 2000) (Faghri & Hamad, 2002). When the congestion level is increased the drivers notice this as delays in the traffic (Taylor, Woolley, & Zito, 2000), i.e., the travel time for the individual driver is simply...... increased. In the initial study presented here, the time it takes to pass an intersection is studied in details. Two major signal-controlled four-way intersections in the center of the city Aalborg are studied in details to estimate the congestion levels in these intersections, based on the time it takes...

    Skid avoidance training is a recent approach to driver training and has been employed in various countries with a high degree of success. Among top ranked countries, motor vehicle incidents trends indicate higher incident rates among drivers are often due to lack of knowledge, experience and risk awareness. If lowered age limit experience is attained under direct supervision and in safe training conditions, it was suggested, incident frequency is reduced. A Norway study confirmed an increase in vehicle incident rates after drivers had received skid control training. The drivers were unable to maintain skill levels needed to react to critical driving tasks and had unrealistic expectations of skill after training. However, a skid avoidance training program launched in Sweden in 1999 has resulted in a 50 per cent reduction of vehicle incidents in the last 2 years. Details of the Skidcar System were presented, including details of the driving simulator, where simulation of actual driving situations is achieved by simply adjusting the amount of grip the vehicle has with the driving surface. Instructors modify driving behaviors based upon the driver's ability to maintain grip. There are over 200 units in North America. In addition, a Proactive Light Vehicle Driver Training/ Heavy Vehicle Assessment Program was initiated in 2003, with a motor vehicle incident rate reduction of 50 per cent at the end of 2004. Various examples of situations in which drivers have used their skid avoidance skills to avoid incidents were included. It was noted that the trend among driver training professionals has been towards decision-based rather than skills-based training, as skills-based training will diminish over time, and requires frequent re-training periods. Cognitive and perceptual skills were examined, as well as cognitive, associative and autonomous learning phases. It was concluded that skid avoidance is largely a decision-based skill. tabs, figs.
