    Full Text Available Nowadays, technology development demands candidates of employees to be highly qualified workers as companies or manufacturers make use of machinary. Therefore, they are supposed to to master English as the language of operation manual. With good English proficiency, workers are able to operate the machine in their workplace correctly and human errors could be eliminated. In other words, the companies will not get loss if all workers understand English in practical way. To answer this challange, vocational schools play an important role in providing ready-work graduates. Through curriculum design and appropriate teaching materials, students are taught to achieve the competence stated there. This research was conducted to describe the utility of English teaching materials of vocational schools to the application in work places, in this case, kretek industry in Kudus. A descriptive need analysis was used to analyze the data that was collected through a deep interview. The result of the research shows that emplyees perceived that vocabulary is the most important language component to learn. In addition, they considered skill mostly needed is reading comprehension. In other words, the materials are not very relevant to the need of kretek industry in Kudus. Hopefully, this research can assists English teachers of vocational schools to consider the students‘ need and develop the suitable materials for them.

    2016-05-01

    To evaluate relevant optical properties of esthetic direct restorative materials focusing on whitened and translucent shades. Enamel (E), body (B), dentin (D), translucent (T) and whitened (Wh) shades for E (WhE) and B (WhB) from a restorative system (Filtek Supreme XTE, 3M ESPE) were evaluated. Samples (1 mm thick) were prepared. Spectral reflectance (R%) and color coordinates (L*, a*, b*, C* and h°) were measured against black and white backgrounds, using a spectroradiometer, in a viewing booth, with CIE D65 illuminant and d/0° geometry. Scattering (S) and absorption (K) coefficients and transmittance (T%) were calculated using Kubelka-Munk's equations. Translucency (TP) and opalescence (OP) parameters and whiteness index (W*) were obtained from differences of CIELAB color coordinates. R%, S, K and T% curves from all shades were compared using VAF (Variance Accounting For) coefficient with Cauchy-Schwarz inequality. Color coordinates and optical parameters were statistically analyzed using one-way ANOVA, Tukey's test with Bonferroni correction (α=0.0007). Spectral behavior of R% and S were different for T shades. In addition, T shades showed the lowest R%, S and K values, as well as the highest T%, TP an OP values. In most cases, WhB shades showed different color and optical properties (including TP and W*) than their corresponding B shades. WhE shades showed similar mean W* values and higher mean T% and TP values than E shades. When using whitened or translucent composites, the final color is influenced not only by the intraoral background but also by the color and optical properties of multilayers used in the esthetic restoration.

    2016-01-01

    Objectives This study examines the perceived impact of a novel clinical teaching method based on FAIR principles (feedback, activity, individuality and relevance) on students’ learning on clinical placement. Methods This was a qualitative research study. Participants were third year and final year medical students attached to one UK vascular firm over a four-year period (N=108). Students were asked to write a reflective essay on how FAIRness approach differs from previous clinical placement, and its advantages and disadvantages. Essays were thematically analysed and globally rated (positive, negative or neutral) by two independent researchers. Results Over 90% of essays reported positive experiences of feedback, activity, individuality and relevance model.  The model provided multifaceted feedback; active participation; longitudinal improvement; relevance to stage of learning and future goals; structured teaching; professional development; safe learning environment; consultant involvement in teaching. Students perceived preparation for tutorials to be time intensive for tutors/students; a lack of teaching on medical sciences and direct observation of performance; more than once weekly sessions would be beneficial; some issues with peer and public feedback, relevance to upcoming exam and large group sizes. Students described negative experiences of “standard” clinical teaching. Conclusions Progressive teaching programmes based on the FAIRness principles, feedback, activity, individuality and relevance, could be used as a model to improve current undergraduate clinical teaching.

  3. Are the concepts of andragogy and pedagogy relevant to veterinary undergraduate teaching?

    Science.gov (United States)

    Parkinson, Tim J; St George, Alison M

    2003-01-01

    Knowles and colleagues have described teaching methods as being either teacher centered, with dependent learning (pedagogy), or learner centered, with independent learning underpinned by the learners' experience and intrinsic motivation (andragogy). This paper argues that both models can be recognized within veterinary undergraduate programs. Veterinary students enter the program with a high level of intrinsic motivation and are prepared to invest considerably in comprehending the material that is presented to them. While this should result in learners whose behavior fits the assumptions underlying andragogy, information overload, poor communication of the relevance of material, teaching by transmission, and examination by memorization often confine learning to the dependent learning characteristic of pedagogical approaches. Students' experience and practical ability should develop as they progress through the program. Drawing upon experience provides opportunities for both fleshing out and putting in context the declarative knowledge from the didactic components of the curriculum. Where this is achieved (either in the clinical or preclinical curriculum), students' motivation and interest is stimulated, resulting in andragogical responses of enhanced motivation and engagement with the subject. Pedagogy and andragogy can, however, be complementary, rather than antithetical. Students enter a new subject with minimal experience and little knowledge about it, so a pedagogical methodology may be the most efficient way of initiating understanding. However, as understanding develops, an andragogical method becomes more appropriate, progressively developing students' independence of learning. The cycle may repeat itself during the program, with the balance changing along with changes in knowledge, goals, experience, and context.

    El Sayed, Khalid A; Chelette, Candace T

    2014-03-12

    To design, implement, and evaluate student performance on clinically relevant chemical and spectral laboratory exercises on antibiotics. In the first of 2 exercises, second-year pharmacy students enrolled in an integrated laboratory sequence course studied the aqueous stability of ß-lactam antibiotics using a spectral visual approach. In a second exercise, students studied the tendency of tetracycline, rifamycins, and fluoroquinolones to form insoluble chelate complexes (turbidity) with polyvalent metals. On a survey to assess achievement of class learning objectives, students agreed the laboratory activities helped them better retain important information concerning antibiotic stability and interactions. A significant improvement was observed in performance on examination questions related to the laboratory topics for 2012 and 2013 students compared to 2011 students who did not complete the laboratory. A 1-year follow-up examination question administered in a separate course showed >75% of the students were able to identify rifamycins-food interactions compared with laboratory exercises. The use of spectral visual approaches allowed students to investigate antibiotic stability and interactions, thus reinforcing the clinical relevance of medicinal chemistry. Students' performance on questions at the 1-year follow-up suggested increased retention of the concepts learned as a result of completing the exercises.

  7. On-line radiation teaching materials using IT technology

    2005-01-01

    We developed the on-line radiation teaching materials using the Internet, in order to provide the teaching support materials of atomic power and radiation educations in on-school study, as well as to create the complementary study system in off-school study. The themes of teaching materials were selected from requests by teachers. In the case of an elementary school, the teaching material 'an environmental problem and atomic power' was created as the aggregate of each content for study without boundary between subjects. The teaching material 'medical treatment and radiation' was created for junior high school students to raise the individual knowledge. In the case of a high school, the teaching material nucleus and radiation' was prepared to supplement the physical study of students. The on-line teaching materials were tried to 300 junior high school and high school students, 68% of students answered that the teaching material is effective to understand atomic power and radiation, though 17% answered they were not effective. Although there are problems to prepare IT learning equipments and learning follow-up system in the material, it is suggested that the on-line teaching materials will provide the novel learning system including debates for the study. This method has no limitation of time and place. (author)

    Hobson, Art

    1998-04-01

    If America is to achieve the science literacy that is ssential to industrialized democracy, all students must study such topics as scientific methodology, pseudoscience, critical thinking, ozone depletion, technological risk, and global warming. My large-enrollment liberal-arts physics course covers the great principles of physics along with several such philosophical and societal topics. Students find these topics relevant and fascinating, leading to strong course evaluations and large enrollments by non-scientists even in courses labeled physics. I will describe this course and present some evidence indicating that the course is effective in communicating physics and its interdisciplinary connections. A textbook, Physics: Concepts and Connections (Prentice Hall, 1995, 2nd edition to appear in June 1998), is available.

    This study presents results of a survey conducted at the Federal Institution of Education, Science and Technology in the North of Minas Gerais (IFNMG), and aimed to investigate the potentialities of the use of interactive materials in the teaching of astronomy. An advanced training course with involved learning activities about basic concepts of astronomy was offered to thirty-two Licenciate students in Physics, Mathematics and Biological Science. The following steps were to be taken: i) analysis of the pedagogical projects (PPC) of the licenciates at the IFNMG, research locus of its Campus Januária; ii) analysis of students' preconceptions about astronomy and digital technologies, identified by the application of an initial questionnaire; iii) preparation of the course taking into account the students' previous knowledge; iv) application of the education proposal developed under part-time presence modality, using various interactive tools; v) application and analysis of the final questionnaire. The test was conducted with the qualitative and quantitative methodology, combined with a content analysis. The results indicated that in the IFNMG only the licenciate-course in physics includes astronomy content diluted in various subjects of the curriculum; the rates of students prior knowledge in relation to astronomy was low; an evidence of meaningful learning of the concepts related to astronomy, and of viability of resource use involving digital technologies in the Teaching of astronomy, which may contribute to the broadening of methodological options of future teachers and meet their training needs.

  16. Analysis of carbon based materials under fusion relevant thermal loads

    International Nuclear Information System (INIS)

    Compan, Jeremie Saint-Helene

    2008-01-01

    Carbon based materials (CBMs) are used in fusion devices as plasma facing materials for decades. They have been selected due to the inherent advantages of carbon for fusion applications. The main ones are its low atomic number and the fact that it does not melt but sublimate (above 3000 C) under the planned working conditions. In addition, graphitic materials retain their mechanical properties at elevated temperatures and their thermal shock resistance is one of the highest, making them suitable for thermal management purpose during long or extremely short heat pulses. Nuclear grade fine grain graphite was the prime form of CBM which was set as a standard but when it comes to large fusion devices created nowadays, thermo-mechanical constraints created during transient heat loads (few GW.m-2 can be deposited in few ms) are so high that carbon/carbon composites (so-called Carbon Fiber Composites (CFCs)) have to be utilized. CFCs can achieve superior thermal conductivity as well as mechanical properties than fine grain graphite. However, all the thermo-mechanical properties of CFCs are highly dependent on the loading direction as a consequence of the graphite structure. In this work, the background on the anisotropy of the graphitic structures but also on the production of fine grain graphite and CFCs is highlighted, showing the major principles which are relevant for the further understanding of the study. Nine advanced CBMs were then compared in terms of microstructure and thermo-mechanical properties. Among them, two fine grain graphites were considered as useful reference materials to allow comparing advantages reached by the developed CFCs. The presented microstructural investigation methods permitted to make statements which can be applied for CFCs presenting similarities in terms of fiber architecture. Determination of the volumetric percentage of the major sub-units of CFCs, i.e. laminates, felt layers or needled fiber groups, lead to a better understanding on

    Full Text Available In this rapidly changing age, with virtually all information available on the Internet including courses, students may not find any reason to physically attend the lectures. In spite of the many benefits the online lectures and materials bring to teaching, this drift from the traditional (norm face-to-face lectures is also creating further barriers, such as difficulty in communicating and building personal relationships, between students and instructor. In this paper we carry out a study that presents and analyzes factors that motivate students to attend a (1 face-to-face instruction in-class versus an (2 online class. This study is based on an anonymous and voluntary survey that was conducted in the School of Engineering at University of Victoria, BC, Canada. This paper presents and shares the detailed results and analysis of this survey that also includes some interesting and useful comments from the students.

  1. Regulations relevant to the transport of radioactive materials in Switzerland

    International Nuclear Information System (INIS)

    Smith, L.

    1996-01-01

    As is the case in many countries, the transport of radioactive materials in Switzerland is primarily regulated by the national regulations for the transport of dangerous goods. Currently these regulations, in the case of radioactive material, incorporate the 1985 IAEA Safety Series 6 Regulations for the Safe Transport of Radioactive Material (As amended 1990). However, as is also the case in some other countries, consignors, shippers and carriers of radioactive materials must also comply with additional laws when shipping radioactive materials. The most important of these other laws and their accompanying regulations are those concerned with radiation protection (import, export and carriers licences) and nuclear power (import, export, inland transport and transit licences). This paper sets out to describe the collective requirements resulting from all three of these sets of regulations. (Author)

    Global climate change and energy use are among the most relevant and pressing issues in today’s science curriculum, yet they are also complex topics to teach. The underlying science spans multiple disciplines and is quickly evolving. Moreover, a comprehensive treatment of climate change and energy use must also delve into perspectives not typically addressed in geosciences courses, such as public policy and economics. Thus, faculty attempting to address these timely issues face many challenges. To support faculty in teaching these subjects, the On the Cutting Edge faculty development program has created a series of websites and workshop opportunities to provide faculty with information and resources for teaching about climate and energy. A web-based collection of teaching materials was developed in conjunction with the On the Cutting Edge workshops “Teaching about Energy in Geoscience Courses: Current Research and Pedagogy.” The website is designed to provide faculty with examples, references and ideas for either incorporating energy topics into existing geoscience courses or for designing or refining a course about energy. The website contains a collection of over 30 classroom and lab activities contributed by faculty and covering such diverse topics as renewable energy, energy policy and energy conservation. Course descriptions and syllabi for energy courses address audiences ranging from introductory courses to advanced seminars. Other materials available on the website include a collection of visualizations and animations, a catalog of recommended books, presentations and related references from the teaching energy workshops, and ideas for novel approaches or new topics for teaching about energy in the geosciences. The Teaching Climate Change website hosts large collections of teaching materials spanning many different topics within climate change, climatology and meteorology. Classroom activities highlight diverse pedagogic approaches such as role

    Training for radiation teaching is important because of understanding radiation. Training methods except for a cloud chamber were proposed in this study; for example, drawing a visual image of a sand-picture by scanning its beta-rays with a handy type GM dosimeter. Though training hours are limited, measurement of alpha-, beta- and gamma-rays is useful to understand important characteristics of radiation. So, useful radioactive materials are the keys of radiation training. Small sizes of radioactive minerals, chemical reagent of KCl and radon progeny in the air were excellent radioactive materials for training. The differences between ionization and excitation of radiation, the relationship between penetration powers of radiation and shield effects of materials, the differences between natural radioactive materials and artificial ones, and other extension lectures were taught usefully for every grade as training by using these teaching materials.

  13. Casting materials and their application in research and teaching.

    Science.gov (United States)

    Haenssgen, Kati; Makanya, Andrew N; Djonov, Valentin

    2014-04-01

    From a biological point of view, casting refers to filling of anatomical and/or pathological spaces with extraneous material that reproduces a three-dimensional replica of the space. Casting may be accompanied by additional procedures such as corrosion, in which the soft tissue is digested out, leaving a clean cast, or the material may be mixed with radiopaque substances to allow x-ray photography or micro computed topography (µCT) scanning. Alternatively, clearing of the surrounding soft tissue increases transparency and allows visualization of the casted cavities. Combination of casting with tissue fixation allows anatomical dissection and didactic surgical procedures on the tissue. Casting materials fall into three categories namely, aqueous substances (India ink, Prussian blue ink), pliable materials (gelatins, latex, and silicone rubber), or hard materials (methyl methacrylates, polyurethanes, polyesters, and epoxy resins). Casting has proved invaluable in both teaching and research and many phenomenal biological processes have been discovered through casting. The choice of a particular material depends inter alia on the targeted use and the intended subsequent investigative procedures, such as dissection, microscopy, or µCT. The casting material needs to be pliable where anatomical and surgical manipulations are intended, and capillary-passable for ultrastructural investigations.

    2017-04-01

    Full Text Available As one of authentic materials, magazines can facilitate English language teaching and learning. Teachers and students can use magazines as the authentic materials since they can afford to buy it, it is easy to find, and its content is in accordance with the changing of time. It is inevitable that learning from authentic materials has strong appeal for students. In teaching Morphology, magazine can be used as a tool to demonstrate how new words are formed and in this kind of mass media, most new words first appeared. In morphological process, there are some types of how new words are created. In this research, four types are described, e.g. compounding which forms a word out of two or more root morphemes, blending which creates words from parts of two other words, clipping which is the word formation process consisting in the reduction of a word to one of its parts and acronyms by taking the initial letters of a phrase and making a word out of it. The paper aims to show an effort to enrich students‘ vocabulary by using magazine articles on technology as authentic materials. The result shows that authentic materials related to articles on technology can be a tool for teachers to introduce how new words are formed, and the students can feel the way of word forming because they use the words in their daily-life communication. The research also shows that most of data are relatively new words because the words are not found in the dictionary.

    The Materials Irradiation Experiment (MITE-E) was constructed at the University of Wisconsin-Madison Inertial Electrostatic Confinement Laboratory to test materials for potential use as plasma-facing materials (PFMs) in fusion reactors. PFMs in fusion reactors will be bombarded with x-rays, neutrons, and ions of hydrogen and helium. More needs to be understood about the interactions between the plasma and the materials to validate their use for fusion reactors. The MITE-E simulates some of the fusion reactor conditions by holding samples at temperatures up to 1000 °C while irradiating them with helium or deuterium ions with energies from 10 to 150 keV. The ion gun can irradiate the samples with ion currents of 20 μA–500 μA; the typical current used is 72 μA, which is an average flux of 9 × 10{sup 14} ions/(cm{sup 2} s). The ion gun uses electrostatic lenses to extract and shape the ion beam. A variable power (1-20 W), steady-state, Nd:YAG laser provides additional heating to maintain a constant sample temperature during irradiations. The ion beam current reaching the sample is directly measured and monitored in real-time during irradiations. The ion beam profile has been investigated using a copper sample sputtering experiment. The MITE-E has successfully been used to irradiate polycrystalline and single crystal tungsten samples with helium ions and will continue to be a source of important data for plasma interactions with materials.

    2015-10-30

    Difficulties in updating working memory (WM) may underlie problems with regulating emotions that contribute to depression. To examine the ability of updating affective materials in WM, 33 dysphoric and 34 non-dysphoric participants were asked to evaluate the self-descriptiveness of emotional adjectives and provide answers to self-relevant questions. Within 3-7 days, they completed a two-back task with a series of self-irrelevant or self-relevant emotional words (they had generated previously) and four conditions (match-set, break-set, perseveration-set, and no-set). After the WM task, an unexpected recall task was administered; controls recalled more positive self-relevant words and intrusions while dysphoric participants recalled more negative self-relevant words and intrusions. In break-set trials of the two-back task, dysphoric individuals showed slower response to self-relevant words regardless of valence. In the match-set and perseveration-set trials, dysphoric participants showed delayed response to self-related negative words. Moreover, longer reaction times for self-relevant negative words were correlated with higher rumination and worse depression. The results suggest that dysphoric undergraduates are interfered more by and have a better memory of self-relevant negative stimuli in WM, which is closely correlated with rumination. This study is among the first to confirm the potential mechanism that could underwrite the involvement of self-schema in effectively regulating negative affect. Copyright © 2015 Elsevier Ireland Ltd.

    James Parkinson's 1817 seminal article was not well known in France until 1861, when Jean-Martin Charcot and his friend, Alfred Vulpian, published a detailed description in French of paralysis agitans. Their article provided clinical information to help French physicians make an accurate diagnosis by considering gait, shaking and rigidity as well as masked facies. As Charcot always had a strong desire to teach, this article describes his lessons on Parkinson's disease from 1868 to 1888, and also examines the teaching approach he used to pass on his latest findings to his students and colleagues. Charcot also used his role as thesis advisor to disseminate Parkinson's work, and seven of the theses he oversaw, which until now have been overlooked, reveal another facet of his teacher-student relationship. These dissertations provided Charcot with an opportunity to highlight what he had already identified concerning what is today referred to as 'Parkinson-plus syndromes'. Finally, this report concludes with an historical survey of the teaching materials that Paul Richer and Albert Londe developed for the Master at La Salpêtrière to provide him with visual documentation.

    It has been made clear and possible that problems met in teaching nuclear topics can be remedied with much care and attention to the application of the experimental photographs converted into a classroom science teaching device; a proposal which was conducted at Kyoto University Research Reactor Institute. Under Methodology, materials that comprised the experimentation process were provided with simplicity and clarity. Introductions on how to carry out the experiments were logically arranged so as to ensure systematic execution and organization of experimental processes. The inclusion of the experimental set ups were also manifested and of the experimental results (developed photos) presented in a manner suitably good for learners. Determination of the sequential models of the study was reflected, highlighted and specifically simplified as appropriate as possible. Further results and discussions were not shown but can be proposed and suggested that as to further application of the device, peak area spectral measurement and nuclide identification of irradiated samples can be made possible using DSA-1000 Digital Spectrum Analyzer System for countries equipped with ''high touch'' apparatus and facility as spiral basis for concept development. Production and dissemination of photographs can be realized for schools far beyond to cope and afford to buy these expensive laboratory and experimental facility to perform the same task. (author)

    The objective of this study was to evaluate archaeological materials from underground openings or shallow burial in arid environments relevant to Yucca Mountain and to draw conclusions about how their state and their environment of preservation could be of relevance to design and operational aspects of the high-level waste repository. The study has evaluated materials from cultures in the arid regions of the ancient Middle East and compared them with the preservation of ancient materials in dry cave sites in the Great Basin desert area of Nevada. The emphasis has been on materials found in undisturbed underground openings such as caves and un-backfilled tombs. Long-term preservation of such materials in underground openings and the stability of the openings themselves provide useful analogue information that serves as a reference point for considering the operation and evolution of the Yucca Mountain repository. Being able to shed light, by close physical and environmental analogy, on what happens in underground openings over many thousands of years provides valuable underpinning to illustrations of expected system performance and offers pointers towards optimizing repository system and operational design

    In the last fifty years, science materials issues has required the study of air pollution, water and soil to prevent and remedy the adverse effects of waste originating from anthropogenic activity and the development of new energies and new materials. The teaching of this discipline has been marked by lectures on general lines, materials, disciplines, who explained biased objects of reality, but often forgot the task of reconstruction and integration of such visions. Moving from that model, otherwise quite static, to a dynamic relational model, would in our view, a real revolution in education. This means taking a systematic approach to complex both in interpreting reality and in favor when learning. Children relationships are as important or more than single objects, and it is to discover fundamental organizational principles of phenomena we seek to interpret or in other words, find the pattern that connects. Thus, we must work on relationships and also take into account the relation between the observer and the observed. Educate about relationships means that studies should always be considered within a framework of probabilities, not absolute certainties. This model of systemic thinking, dealing with complexity, is a possibility to bring coherence to our educational work, because the complexity is not taught, complexity is live, so that complex thinking is extended (and fed) in a form educate complex. It is the task of teaching to help people move from level to level of decision reviews. This means that systems thinking should be extended in a local action, action that engages the individual and the environment. Science Materials has emerged as a discipline of free choice for pupils attending chemical engineering which has been assigned 6.0 credits. The chemical engineer's professional profile within the current framework is defined as a professional knowledge as a specialization technical / functional, working in a learning organization and the formation of

  10. Strength behaviour of sintered steel from the view of design-relevant material data

    International Nuclear Information System (INIS)

    Sonsino, C.M.; Esper, F.J.; Leuze, G.

    1982-01-01

    A reliable design of sintered components and an aimed material's selection requires the knowledge of designrelevant material data as Cyclic stress-strain-curves, crack propagation and fracture toughness properties as well as statistically evaluated S-N-curves, because conventional material data as tensile strength, monotonic yield strength, elongation, area reduction and impact strength can lead to a false estimation of the material's fatigue behaviour. For this reason the powder metallurgical industry began to determine design-relevant material data on the example of the porous Fe-Cu-C- and Fe-Cu-Ni-alloys. The fatigue tests with notched specimen and different modes of loading show that porous sintered parts having mechanical notches are less sensitive to external notches than wrought steel, because crack-propagation is delayed by pores. The possibility to manufacture cyclic hardening alloys, their relative notch-insensitivity and with wrought steel comparable scatter of fatigue properties show the importance of sintered alloys as alternative materials.

    2015-10-01

    Nuclear technologies such as fission and fusion reactors, including associated waste storage and disposal, rely on the availability of not only nuclear fuels but also advanced structural materials. In 2010–2013, the IAEA organized and implemented the Coordinated Research Project (CRP) on Development, Characterization and Testing of Materials of Relevance to Nuclear Energy Sector Using Neutron Beams. A total of 19 institutions from 18 Member States (Argentina, Australia, Brazil, China, Czech Republic, France, Germany, Hungary, Indonesia, Italy, Japan, Netherlands, Republic of Korea, Romania, Russian Federation (two institutions), South Africa, Switzerland and United States of America) cooperated with the main objective to address the use of various neutron beam techniques for characterization, testing and qualification of materials and components produced or under development for applications in the nuclear energy sector. This CRP aimed to bring stakeholders and end users of research reactors and accelerator based neutron sources together for the enhanced use of available facilities and development of new infrastructures for applied materials research. Work envisioned under this CRP was related to the optimization and validation of neutron beam techniques, including facility and instrument modifications/optimizations as well as improved data acquisition, processing and analysis systems. Particular emphasis was placed on variable environments during material characterization and testing as required by some applications such as intensive irradiation load, high temperature and high pressure conditions, and the presence of strong magnetic fields. Targeted neutron beam techniques were neutron diffraction, small angle neutron scattering and digital neutron radiography/tomography. This publication is a compilation of the main results and findings of the CRP, and the CD-ROM accompanying this publication contains 19 reports with additional relevant technical details

    The schoolchild of a Japan likes the universe primarily and an inquisitive mind is also considered to be a high. It appears also in children having raised interest concern to astronomical phenomena, such as the space probe "Hayabusa", solar eclipse, and solar Face passage of Venus, in recent Japan. However, generally aside from a child's interest concern, a time and a space concept are difficult for the astronomical phenomenon requested by school education. It is a big problem not only for student but also for teacher. In this presentation, we propose the teaching-materials development which used a meteorite and cosmic dust. Since these teaching materials can touch thing, a student actually taking in his hand, or observing under a microscope, leading to the study understanding accompanied by realization is expected. It looks up at and observes a Star Burst and a constellation. However, acquisition of recognition that it is possible to take in its hand simultaneously and to observe is important. About the meteorite to observe, we can purchase from a special contractor. About cosmic dust, the sample extraction from the concrete floor of the roof of a school building is possible.

    PFMs (Plasma-facing materials: ITER grade stainless steel, beryllium, and ferritic-martensitic steels) as well as deposited erosion products of PFCs (Be-like, tungsten, and carbon based) were tested in QSPA under photonic heat loads relevant to those expected from photon radiation during disruptions mitigated by massive gas injection in ITER. Repeated pulses slightly above the melting threshold on the bulk materials eventually lead to a regular, "corrugated" surface, with hills and valleys spaced by 0.2-2 mm. The results indicate that hill growth (growth rate of ∼1 μm per pulse) and sample thinning in the valleys is a result of melt-layer redistribution. The measurements on the 316L(N)-IG indicate that the amount of tritium absorbed by the sample from the gas phase significantly increases with pulse number as well as the modified layer thickness. Repeated pulses significantly below the melting threshold on the deposited erosion products lead to a decrease of hydrogen isotopes trapped during the deposition of the eroded material.

Three concentrations materials for high, middle and low were dubbed with Sini decoction as a model drug, and pretreated by 50 thousand relative molecular weight cut-off ultrafiltration membrane. The viscosity, turbidity, conductivity, salinity, TDS, pH value and osmotic pressure of each sample were determined after the reverse osmosis to study the physical and chemical parameters between their respective correlations with the osmotic pressure, and characterized by HPLC chromatograms showing changes before and after the main chemical composition of samples of reverse osmosis. Conductivity-osmotic pressure, salinity-osmotic pressure of the linear correlation coefficient, TDS-osmotic pressure between the three sets of parameters were 0.963 8, 0.932 7, 0.973 7, respectively. Reverse osmosis concentrate and its characteristic spectrum ultrafiltrate HPLC similarity were up to 0. 968 or more, except the low concentrations. There is a significant correlation between the three physicochemical parameters (conductivity, salinity, TDS) and osmotic pressure of each sample system, and there is also significant linear correlation between salinity, conductivity, TDS. The original chemical composition of Sini decoction material concentrate was completely remained after the process of reverse osmosis.

    PFMs (Plasma-facing materials: ITER grade stainless steel, beryllium, and ferritic–martensitic steels) as well as deposited erosion products of PFCs (Be-like, tungsten, and carbon based) were tested in QSPA under photonic heat loads relevant to those expected from photon radiation during disruptions mitigated by massive gas injection in ITER. Repeated pulses slightly above the melting threshold on the bulk materials eventually lead to a regular, “corrugated” surface, with hills and valleys spaced by 0.2–2 mm. The results indicate that hill growth (growth rate of ∼1 μm per pulse) and sample thinning in the valleys is a result of melt-layer redistribution. The measurements on the 316L(N)-IG indicate that the amount of tritium absorbed by the sample from the gas phase significantly increases with pulse number as well as the modified layer thickness. Repeated pulses significantly below the melting threshold on the deposited erosion products lead to a decrease of hydrogen isotopes trapped during the deposition of the eroded material.

    The phenomenal popularity of social networking sites has been used globally by medical professionals to boost professional associations and scientific developments. They have tremendous potential to forge professional liaisons, generate employment,upgrading skills and publicizing scientific achievements. We highlight the role of social networking mediums in influencing teaching, training and research in anaesthesiology. The growth of social networking sites have been prompted by the limitations of previous facilities in terms of ease of data and interface sharing and the amalgamation of audio visual aids on common platforms in the newer facilities. Contemporary social networking sites like Facebook, Twitter, Tumblr,Linkedn etc and their respective features based on anaesthesiology training or practice have been discussed. A host of advantages which these sites confer are also discussed. Likewise the potential pitfalls and drawbacks of these facilities have also been addressed. Social networking sites have immense potential for development of training and research in Anaesthesiology. However responsible and cautious utilization is advocated.

    When combustible materials ignite and burn, the potential for fire growth and flame spread represents an obvious hazard, but during these processes of ignition and flaming, other life hazards present themselves and should be included to ensure an effective overall analysis of the relevant fire hazards. In particular, the gases and smoke produced both during the smoldering stages of fires leading to ignition and during the advanced flaming stages of a developing fire serve to contaminate the surrounding atmosphere, potentially producing elevated levels of toxicity and high levels of smoke obscuration that render the environment untenable. In underground mines, these hazards may be exacerbated by the existing forced ventilation that can carry the gases and smoke to locations far-removed from the fire location. Clearly, materials that require high temperatures (above 1400 K) and that exhibit low mass loss during thermal decomposition, or that require high heat fluxes or heat transfer rates to ignite represent less of a hazard than materials that decompose at low temperatures or ignite at low levels of heat flux. In order to define and quantify some possible parameters that can be used to assess these hazards, small-scale laboratory experiments were conducted in a number of configurations to measure: 1) the toxic gases and smoke produced both during non-flaming and flaming combustion; 2) mass loss rates as a function of temperature to determine ease of thermal decomposition; and 3) mass loss rates and times to ignition as a function of incident heat flux. This paper describes the experiments that were conducted, their results, and the development of a set of parameters that could possibly be used to assess the overall fire hazard of combustible materials using small scale laboratory experiments.

    2014-01-01

    Full Text Available The paper substantiates the need for profile training in mathematical modeling for pedagogical students, caused by the total penetration of mathematics into different sciences, including the humanities; fast development of the information communications technologies; and growing importance of mathematical modeling, combining the informal scientific and formal mathematical languages with the unique opportunities of computer programming. The author singles out the reasons for mastering and using the mathematical apparatus by teaches in every discipline. Indeed, among all the modern mathematical methods and ideas, mathematical modeling retains its priority in all professional spheres. Therefore, the discipline of “Mathematical Modeling” can play an important role in integrating different components of specialists training in various profiles. By mastering the basics of mathematical modeling, students acquire skills of methodological thinking; learn the principles of analysis, synthesis, generalization of ideas and methods in different disciplines and scientific spheres; and achieve general culture competences. In conclusion, the author recommends incorporating the “Methods of Profile Training in Mathematical Modeling” into the pedagogical magistracy curricula. 

  20. Electro-Analytical Study of Material Interfaces Relevant for Chemical Mechanical Planarization and Lithium Ion Batteries

    Turk, Michael C.

    galvanic corrosions in chemically controlled low-pressure CMP. The CMP specific functions of the slurry components are characterized in the tribo-electro-analytical approach by using voltammetry, open circuit potential (OCP) measurements and electrochemical impedance spectroscopy (EIS) in the presence as well as in the absence of surface abrasion, both with and without the inclusion of colloidal silica (SiO2) abrasives. The results are used to understand the reaction mechanisms responsible for supporting material removal and corrosion suppression. The project carried out in the area of Li ion batteries (LIBs) uses electro-analytical techniques to probe electrolyte characteristics as well as electrode material performance. The investigation concentrates on optimizing a tactically chosen set of electrolyte compositions for low-to-moderate temperature applications of lithium titanium oxide (LTO), a relatively new anode material for such batteries. For this application, mixtures of non-aqueous carbonate based solvents are studied in combination with lithium perchlorate. The temperature dependent conductivities of the electrolytes are rigorously measured and analyzed using EIS. The experimental considerations and the working principle of this EIS based approach are carefully examined and standardized in the course of this study. These experiments also investigate the effects of temperature variations (below room temperature) on the solid electrolyte interphase (SEI) formation characteristics of LTO in the given electrolytes. This dissertation is organized as follows: Each experimental system and its relevance for practical applications are briefly introduced in each chapter. The experimental approach and the motivation for carrying out the investigation are also noted in that context. The experimental details specific to the particular study are described. This is followed by the results and their discussion, and subsequently, by the specific conclusions drawn from the given

    Secondary organic aerosol (SOA) particles formed from the oxidation of biogenic volatile organic compounds (BVOCs) remain a principal, yet elusive, class of airborne particulate matter that impacts the Earth's radiation budget. Given the characteristic molecular complexity comprising biogenic SOA particles, chemical information selective to the gas-aerosol interface may be valuable in the investigation of such systems, as surface considerations likely dictate the phenomena driving particle evolution mechanisms and climate effects. In particular, cloud activation processes may be parameterized using the surface tension depression that coincides with partitioning of surface-active organic species to the gas-droplet interface. However, the extent to which surface chemical processes, such as cloud droplet condensation, are influenced by the chemical structure and reactivity of individual surface-active molecules in SOA particles is largely unknown. We seek to study terpene-derived organic species relevant to the surfaces of biogenic SOA particles via synthesis of putative oxidation products followed by analysis using surface-selective physicochemical measurements. Using dynamic surface tension measurements, considerable differences are observed in the surface tension depression of aqueous pendant droplets that contain synthetically prepared ozonolysis products derived from abundant terpene precursors. Furthermore, sum frequency generation spectroscopy is utilized for comparison of the surface vibrational spectral responses of synthesized reference compounds with those observed for laboratory aerosol toward probing the surface composition of SOA material. Such ongoing findings highlight the underlying importance of molecular structure and reactivity when considering the surface chemistry of biogenic terpene-derived atmospheric aerosols.

    Cationic clays are very extended compounds on the earth surface so they constitute the main component of soils and sedimentary rocks. Due to their presence and special properties that they have, mankind has used them with therapeutic aims from Prehistory, not being rare to find references to this subject in works of classic authors. During the Renaissance and with the appearance of the first Pharmacopeia, its use was regulated to a certain extent. The scientific development reached during the XXth century has allowed to understand and to study the reasons of the useful and peculiar properties of clays, directly related to their colloidal size and crystalline structure. These properties are translated in a high specific surface area, optimal rheological properties and/or excellent sorptive capacity; everything makes cationic clays very useful for a wide range of applications. In the field of health, cationic clays are used in Pharmaceutical Technology and Dermopharmacy as ideal excipients and substances of suitable biological activity due to their chemical inertness and low or null toxicity for the patient (Carretero, 2002; Lopez Galindo et al., 2005; Choy et al., 2007; del Hoyo, 2007). Cationic clays can be used in a wide range of applications in health. However, it must be also considered that the risk exposure to cationic clays may cause several diseases, as it has been seen above. Cationic clays have been used as excipients and active principles in the pharmaceutical industry. The last tendencies are their use in geomedicine, as much to come up as to treat diseases. One stands out his presence in spas and aesthetic medicine. Development of new pharmaceutical formulations is observed, based on cationic clays, for cancer therapy. It has to emphasize the importance in the synthesis of biosensors with cationic clays. Cationic clays can be considered a group of promising materials in the development of new health applications.

    Full Text Available The tenth graders of State Senior High School 2 Semarang had problems to write their experiences. Unfortunately the existing materials were not appropriate to facilitate the learners to write recount texts. Hence, this study would like to develop environment – based materials to teach writing recount texts. It was inspired by the previous studies held by Gürsoy (2010 and Hauschild (2012. The materials were expected to improve learners’ writing competence of recount texts by applying topics which learners found in their daily lives, that is, environmental education. This study employed Research and Development design adapted from Borg and Gall (2003. The study found that applying the environment – based materials to teach writing recount texts gained positive effects. Moreover, the test of effectiveness reported significant improvement. The average score of pre-test was 48.94 and of post-test was 81.61. Therefore, English teachers are suggested to employ the materials. It is also necessary to conduct further studies to gain more positive effects toward teaching and learning process and to improve the learners’ writing competence. Keywords: Teaching writing; recount text; environment – based materials; contextual teaching and learningCopyright © 2015 by Al-Ta'lim All right reserved

    Full Text Available The Ministerial Regulation Number 16 of the year 2007 on academic qualification standards and teacher competencies requires teachers to demonstrate four competencies: personality, social, pedagogical, and  professional. However, there are two competencies (pedagogical and professional which become the stumbling obstacles for teachers of English in their professional involvement. Therefore, this study was designed to aim at: (1 creating a conceptual framework for enhancing teachers’ capabilities in developing and implementing teaching materials; (2 designing a model of IHT to improve the ability of teachers to develop and implement the use of teaching materials; and (3 piloting and implementing the IHT model in teacher training programs. The method used in the data analysis adopted a qualitative design with reference especially to the theory of the development of teaching materials (Crowford: 2002 and the design of IHT (Wallace: 1993. The results showed that most respondents tended to resort to the textbook as the primary source for students’ learning activities, with some enrichment materials obtained from the Internet and other sources. Nevertheless most of the teachers were still found to encounter quite a few obstacles in developing their teaching-learning materials, appropriate to the topics as indicated in the syllabus and to the student characteristics. To alleviate this hurdle, the IHT model to be incorporated in a teacher training program could be an effective alternative to improve the ability of the teachers in developing their English teaching-learning materials.

    2018-05-01

    In view of the scattered experimental projects in practical courses of civil engineering materials, the poor practical ability of students and the disconnection between practical teaching and theoretical teaching, this paper proposes a practical teaching procedure. Firstly, the single experiment should be offered which emphasizes on improving the students’ basic experimental operating ability. Secondly, the compressive experiment is offered and the overall quality of students can be examined in the form of project team. In order to investigate the effect of teaching reform, the comparative analysis of the students of three grades (2014, 2015 and 2016) majored in civil engineering was conducted. The result shows that the students’ ability of experimental operation is obviously improved by using the project driven method-based teaching reform. Besides, the students’ ability to analyse and solve problems has also been improved.

  19. Enhanced surface functionality via plasma modification and plasma deposition techniques to create more biologically relevant materials

    Science.gov (United States)

    Shearer, Jeffrey C.

    Functionalizing nanoparticles and other unusually shaped substrates to create more biologically relevant materials has become central to a wide range of research programs. One of the primary challenges in this field is creating highly functionalized surfaces without modifying the underlying bulk material. Traditional wet chemistry techniques utilize thin film depositions to functionalize nanomaterials with oxygen and nitrogen containing functional groups, such as --OH and --NHx. These functional groups can serve to create surfaces that are amenable to cell adhesion or can act as reactive groups for further attachment of larger structures, such as macromolecules or antiviral agents. Additional layers, such as SiO2, are often added between the nanomaterial and the functionalized coating to act as a barrier films, adhesion layers, and to increase overall hydrophilicity. However, some wet chemistry techniques can damage the bulk material during processing. This dissertation examines the use of plasma processing as an alternative method for producing these highly functionalized surfaces on nanoparticles and polymeric scaffolds through the use of plasma modification and plasma enhanced chemical vapor deposition techniques. Specifically, this dissertation will focus on (1) plasma deposition of SiO2 barrier films on nanoparticle substrates; (2) surface functionalization of amine and alcohol groups through (a) plasma co-polymerization and (b) plasma modification; and (3) the design and construction of plasma hardware to facilitate plasma processing of nanoparticles and polymeric scaffolds. The body of work presented herein first examines the fabrication of composite nanoparticles by plasma processing.

    Writing teaching materials is one of the generic pedagogical skills. Teachers and pre-service teachers should be trained to have the skills of writing teaching materials. This study examines the factors that influence the skills of writing in the disciplines among pre-service physics teachers. This study in particular aims to contribute to the development of science writing in the disciplines and to the organization of workshops on writing teaching materials for pre-service teachers. The problems of this research are formulated in the question of what are the factors that influence the skills of pre-service physics teachers in writing teaching materials. The research adopted mixed methods with embedded experimental design. The research subjects were 18 students enrolled in the school physics course. The instruments used consisted of conceptual understanding tests, learning strategy questionnaire, tests of the multiple representation skills, and one-on-one semi- structured interview. Results of data analysis show that the ability and skills of writing physics teaching materials of the pre- service physics teachers are determined by the factors of conceptual understanding of the subject matter with a contribution of 20%, the skills of making multiple representations of concepts with a contribution of 9.8% and students' self-regulation and learning strategy with a contribution of 33.5%. There are other factors that have not been investigated in this study; therefore, it is recommended that future research conduct further investigation on other factors that influence pre-service teachers' skills in writing physics teaching materials.

    2012-06-01

    Full Text Available This paper presents a method of organizing electronic teaching materials based on their role in the teaching process rather than their technical structure. Our method allows SCORM materials stored as e-learning courses („electronic books” to be subdivided and structured so that content can be used in multiple contexts. As a standard, SCORM defines rules for organizing content, but not how to divide and structure it. Our method uses UCTS nomenclature to divide content, define relationships between content entities, and aggregate those entities into courses. This allows content to be shared in different implementations of SCORM while guaranteeing that usability and consistency are maintained.

  13. Exploring how New Teaching Materials Influence the Beliefs and Practices of Instructors and Students' Attitudes about Geoscience

    Science.gov (United States)

    Pelch, Michael Anthony

    STEM educational reform encourages a transition from instructor-centered passive learning classrooms to student-centered, active learning environments. Instructors adopting these changes incorporate research-validated teaching practices that improve student learning. Professional development that trains faculty to implement instructional reforms plays a key role in supporting this transition. Effective professional development features authentic, rigorous experiences of sufficient duration. We investigated changes in the teaching beliefs of college faculty resulting from their participation in InTeGrate project that guided them in the development of reformed instructional materials for introductory college science courses. A convergent parallel mixed methods design was employed using the Teacher Belief Interview, the Beliefs About Reformed Science Teaching and Learning survey and participants' reflections on their experience to characterize pedagogical beliefs at different stages of their professional development. Qualitative and quantitative data show a congruent change toward reformed pedagogical beliefs for the majority of participants. The majority of participants' TBI scores improved toward more student-centered pedagogical beliefs. Instructors who began with the most traditional pedagogical beliefs showed the greatest gains. Interview data and participants' reflections aligned with the characteristics of effective professional development. Merged results suggest that the most significant changes occurred in areas strongly influenced by situational classroom factors. Introductory geoscience courses play a crucial role in recruiting new geoscience majors but we know relatively little about how students' attitudes and motivations are impacted by their experiences in geoscience classes. Students' attitudes toward science and its relevance are complex and are dependent upon the context in which they encounter science. Recent investigations into the attitudes of

    1984-10-01

    At the request of the Basalt Waste Isolation Project, the Materials Characterization Center has collected and developed a set of procedures into a waste form compliance test method (MCC-14.4). The purpose of the test is to measure the steady-state concentrations of specified radionuclides in solutions contacting a waste form material. The test method uses a crushed waste form and basalt material suspended in a synthetic basalt groundwater and agitated for up to three months at 150 0 C under anoxic conditions. Elemental and radioisotopic analyses are made on filtered and unfiltered aliquots of the solution. Replicate experiments are performed and simultaneous tests are conducted with an approved test material (ATM) to help ensure precise and reliable data for the actual waste form material. Various features of the test method, equipment, and test conditions are reviewed. Experimental testing using actinide-doped borosilicate glasses are also discussed. 9 references, 2 tables

  15. Materials degradation in fission reactors: Lessons learned of relevance to fusion reactor systems

    International Nuclear Information System (INIS)

    Was, Gary S.

    2007-01-01

    The management of materials in power reactor systems has become a critically important activity in assuring the safe, reliable and economical operation of these facilities. Over the years, the commercial nuclear power reactor industry has faced numerous 'surprises' and unexpected occurrences in materials. Mitigation strategies have sometimes solved one problem at the expense of creating another. Other problems have been solved successfully and have motivated the development of techniques to foresee problems before they occur. This paper focuses on three aspects of fission reactor experience that may benefit future fusion systems. The first is identification of parameters and processes that have had a large impact on the behavior of materials in fission systems such as temperature, dose rate, surface condition, gradients, metallurgical variability and effects of the environment. The second is the development of materials performance and failure models to provide a basis for assuring component integrity. Last is the development of proactive materials management programs that identify and pre-empt degradation processes before they can become problems. These aspects of LWR experience along with the growing experience with materials in the more demanding advanced fission reactor systems form the basis for a set of 'lessons learned' to aid in the successful management of materials in fusion reactor systems

    Full Text Available Many language teachers around the world design materials to supplement those they are provided with to address the needs of the learners in their particular context. This is a task which requires practical knowledge of various kinds relating to learners and language learning, teaching and materials design. However, while there is a growing body of research into the practical knowledge of language teachers, little of this is longitudinal and there is a lack of research into how teachers develop as materials designers. This article focuses on one teacher's growth as a DIY (do-it-yourself designer of English language teaching materials during an in-service BA TESOL (teaching English to speakers of other languages programme in the Middle East. Using qualitative case study methodology, I follow the teacher's development over three years, exploring changes in ideas and teaching practices.

    Full Text Available Result of field studies showed low writing skill of teachers in teaching material. The root of the problem lies in their inability on translating description of teaching material into writing. This research focused on the effectiveness of scaffolding design. The scaffolding design was tested in the selected topics of physics courses for pre-service teachers through learning to write activity approach. The treatment effectiveness was determined by considering the effect size and normalized gain percentage, while the hypothesis was tested using “the Kruskal-Wallis test”. The research results showed that scaffolding between the stages of planning and translating plans into text was effective in improving pre-service physics teachers’ ability of writing physics teaching materials and was similarly effective in improving their conceptual understanding of the topics of electromagnetism, waves, and optics. Learning to write activity implemented in the course of physics with selected topics was effective in improving the ability of pre-service teachers in translating among different modes of representation and making multiple concept representations. The hypothesis test demonstrated that there was a significant difference in the abilities of writing teaching materials and conceptual understanding between experimental and control classes.

    2015-04-01

    GPS devices are common use in the daily life and are used in geography classes increasingly often. Presently, specialist literature is merely descriptive and thematically reduced to the function of orientation. The questions whether they are an applicable tool for teaching earth science circumstances and if the lasting learning success shows any differences compared to normal lessons hold in a class room haven't been answered. Neurobiological and teaching psychological knowledge support the idea that students completing the GPS-based educational trail will learn more successful compared to students in a "normal" class: A successful contextualization of modern geomedia stimulates the motivation. Geocaches are also suitable for didactical structuration. The order of "Geopoints" is chosen in a way that the structure of the landscape is being displayed adequate. The students feel addressed affectively due to the real-life encounters and experience their environment consciously. The presented concept "GPS-based educational trail" is different from a normal geocache, which is merely a hide-and-seek-game. Here, the main focus lays on the field work and earth science. The GPS-decvices are used for the orientation between the Geopoints. In order to get two groups with characteristics as different as possible, due to their developmental psychology, age-related education of cognitive and methodical competence, classes from grade 5 (11 years old) and 11 (17 years old) have been chosen. The different cognitive states of development require different didactical approaches. For the 11 grade the topic "rearrangements of fluvial topography" is a possible one. Using the example of anthropogenic rearrangements of the Rheinaue wetlands near Karlsruhe the interdependency between human and environment can be shown. The "Nördlinger Ries" between the Swabian and the Franconian Jura has been chosen for grade 5. The typical elements of the Swabian Jura (karst formation, hydrogeology

The reason of our work was the intention to both improve the process of teaching and also learning and invalidate the labels owned by biochemistry of hard and high-level-failure subject. The three actors: teachers, students and monitor could act on an integrated basis for the construction of an articulated  pedagogical process between theory/practice and learning signification. Our main objective was to initiate the monitors in teaching practice effected through educational projects aimed at improving the teaching and learning of undergraduate courses and encouraging teacher training, involving teachers and students the guiding condition and monitors, respectively. The methodology was applied in three stages: 1 preparation of teaching materials; 2nd application in class and 3rd students rating of the methodology applied by monitors. The teaching materials presented discussed several biochemistry's topics and students had the opportunity to scaffold their own knowledge actively. Almost 90% considered the tool applied as highly related to classes and 82% considered this way of learning more significant than dialogical lectures. The performance of the monitors, focused on students and their learning, was considered great by students who were more motivated, resulting in the excellent evaluation of the work (100% of acceptance. The failure rate of the subject reduced in the four groups wherein the pedagogical materials were applied. It can demonstrate that both the mastery of scientific content and the pedagogical process involved during the teaching and learning moments are important.

  15. Nuclear weapon relevant materials and preventive arms control. Uranium-free fuels for plutonium elimination and spallation neutron sources

    International Nuclear Information System (INIS)

    Liebert, Wolfgang; Englert, Matthias; Pistner, Christoph

    2009-01-01

    Today, the most significant barrier against the access to nuclear weapons is to take hold on sufficient amounts of nuclear weapon-relevant nuclear materials. It is mainly a matter of fissionable materials (like highly enriched uranium and plutonium) but also of fusionable tritium. These can be used as reactor fuel in civil nuclear programmes but also in nuclear weapon programmes. To stop or to hinder nuclear proliferation, in consequence, there is not only a need to analyse open or covered political objectives and intentions. In the long term, it might be more decisive to analyse the intrinsic civil-military ambivalence of nuclear materials and technologies, which are suitable for sensitive material production. A farsighted strategy to avoid proliferation dangers should take much more account to technical capabilities as it is done in the political debate on nuclear non-proliferation so far. If a technical option is at a state's disposal, it is extremely difficult and lengthy to revert that again. The dangers, which one has to react to, are stemming from already existing stocks of nuclear weapon-relevant materials - in the military as well as in the civil realm - and from existing or future technologies, which are suitable for the production of such materials (cf. info 1 and 2). Therefore, the overall approach of this research project is to strive for a drastic reduction of the access to nuclear weapon-relevant material and its production capabilities. Thus, on one hand the nuclear proliferation by state actors could be answered more effectively, on the other hand by that approach a decisive barrier against the access on nuclear weapons by sub-national groups and terrorists could also be erected. For this purpose, safeguards of the International Atomic Energy Agency (IAEA) and other measures of physical accountancy will remain indispensable elements of arms control. However, one has to consider that the goal of nuclear non-proliferation could not be achieved and

    In a thermonuclear reactor fusion between hydrogen isotopes takes place, producing helium and energy. The so-called divertor is the part of the fusion reactor vessel where the plasma is neutralized in order to exhaust the helium. The surface plates of the divertor are subjected to high heat loads and high fluxes of energetic hydrogen and helium. In the next generation fusion device - the tokamak ITER - the expected conditions at the plates are particle fluxes exceeding 10 24 per second and square metre, particle energies ranging from 1 to 100 eV and an average heat load of 10 MW per square metre. Two materials have been identified as candidates for the ITER divertor plates: carbon and tungsten. Since there are currently no fusion devices that can create these harsh conditions, it is unknown how the materials will behave in terms of erosion and hydrogen retention. To gain more insight in the physical processes under these conditions molecular dynamics simulations have been conducted. Since diamond has been proposed as possible plasma facing material, we have studied erosion and hydrogen retention in diamond and amorphous hydrogenated carbon (a-C:H). As in experiments, diamond shows a lower erosion yield than a-C:H, however the hydrogen retention in diamond is much larger than in a-C:H and also hardly depending on the substrate temperature. This implies that simple heating of the surface is not sufficient to retrieve the hydrogen from diamond material, whereas a-C:H readily releases the retained hydrogen. So, in spite of the higher erosion yield carbon material other than diamond seems more suitable. Experiments suggest that the erosion yield of carbon material decreases with increasing flux. This was studied in our simulations. The results show no flux dependency, suggesting that the observed reduction is not a material property but is caused by external factors as, for example, redeposition of the erosion products. Our study of the redeposition showed that the

    The aim of this study was to evaluate perceptions, barriers, and characteristics of teaching materials to promote healthy eating, as described by teenagers. Four focus groups were conducted with 25 adolescents, including questions on: perceptions regarding diet and motivations to change; concepts of (and barriers to) healthy eating; and characteristics needed for teaching materials to promote healthy eating. The teens were often undecided when attempting to classify a diet as healthy. They generally reported feeling insecure about making dietary changes, but showed adequate notions of healthy eating. The main barriers involved personal and social characteristics: temptation, food flavors, parental influence, and lack of time and options for healthy snacks at school. According to these teenagers, educational materials for promotion of healthy eating should emphasize the immediate benefits and emphasize high-impact messages on the health risks of unhealthy diet.

    Many materials used for energy conversion have a complex structure and chemical composition, knowledge of which is important for both understanding the function of materials and energy conversion systems and for their further development. Synchrotron radiation and neutrons can make an important contribution to understanding the function of such systems. Taking examples from the fields of fuel cells, gas separation membranes, batteries, solar cells, and catalysts, the use of radiography, tomography, diffraction, scattering, and absorption edge spectroscopy is demonstrated. The strength of such methods is the in situ characterization of processes and compositions, and so the focus is on these aspects. (Copyright copyright 2011 WILEY-VCH Verlag GmbH and Co.

  19. Study of the mechanisms of heavy-ion induced desorption on accelerator-relevant materials

    The ion beam loss induced desorption is a performance limitation for low charge state heavy ion accelerators. If charge exchanged projectile ions get lost onto the beam pipe, desorption of gas is stimulated resulting in a pressure increase inside of the synchrotron and thus, a dramatically reduction of the beam life time. To minimize the amount of desorbed gas an experimental program has been started to measure the desorption yields (released gas molecules per incident ion) of various materials and different projectile ions. The present work is a contribution to the understanding of the physical processes behind the ion beam loss induced desorption. The yield measurements by the pressure rise method have been combined for the rst time with in situ ion beam analysis technologies such as ERDA and RBS. With this unique method the desorption behavior of a sample can be correlated to its surface and bulk properties. The performed experiments with 1,4 MeV/u Xenon-Ions show that the ion induced desorption is mainly a surface effect. Sputtered oxide layers or impurities do not contribute to the desorbed gas significantly. Nevertheless bulk properties play an important role in the desorption strength. Pure metallic samples desorb less gas than isolating materials under swift heavy ion irradiation. From the experimental results it was possible to estimate the desorption yields of various materials under ion bombardment by means of an extended inelastic thermal-spike-model. The extension is the combination of the thermal-spike's temperature map with thermal desorption. Within this model the ion induced desorption can be regarded as the release of adsorbates from a transient overheated spot on the samples surface around the ion impact. Finally a copper substrate with a gold coated surface was developed and proposed as a suitable material for a beam loss collimator with minimum desorption to ensure the performance of GSI's SIS18 in high current beam operation.

    Nuclear analytical techniques (NATs), utilizing neutron and proton based nuclear reactions and subsequent measurement of gamma rays, are capable of chemical characterization of various materials at major to trace concentration levels. The present article deals with the recent developments and applications of conventional and k0-based internal monostandard (i) neutron activation analysis (NAA) and (ii) prompt gamma ray NAA (PGNAA) methods as well as (iii) in situ current normalized particle induced gamma ray emission (PIGE). The materials that have been analyzed by NAA and PGNAA include (i) nuclear reactor structural materials like zircaloys, stainless steels, Ni alloys, high purity aluminium and graphite and (ii) uranium oxide, U-Th mixed oxides, uranium ores and minerals. Internal monostandard NAA (IM-NAA) method with in situ detection efficiency was used to analyze large and non-standard geometry samples and standard-less compositional characterization was carried out for zircaloys and stainless steels. PIGE methods using proton beams were standardized for quantification of low Z elements (Li to Ti) and applied for compositional analysis of borosilicate glass and lithium titanate (Li 2 TiO 3 ) samples and quantification of total B and its isotopic composition of B ( 10 B/ 11 B) in boron based neutron absorbers like B 4 C.

    A way to improve the quality of learning in the course of Plant Metabolism in the Department of Biology, State University of Malang, is to develop teaching materials. This research evaluates the needs of bioinformatics-based teaching material in the course Plant Metabolism by the Analyze, Design, Develop, Implement, and Evaluate (ADDIE) development model. Data were collected through questionnaires distributed to the students in the Plant Metabolism course of the Department of Biology, University of Malang, and analysis of the plan of lectures semester (RPS). Learning gains of this course show that it is not yet integrated into the field of bioinformatics. All respondents stated that plant metabolism books do not include bioinformatics and fail to explain the metabolism of a chemical compound of a local plant in Indonesia. Respondents thought that bioinformatics can explain examples and metabolism of a secondary metabolite analysis techniques and discuss potential medicinal compounds from local plants. As many as 65% of the respondents said that the existing metabolism book could not be used to understand secondary metabolism in lectures of plant metabolism. Therefore, the development of teaching materials including plant metabolism-based bioinformatics is important to improve the understanding of the lecture material in plant metabolism.

    In order to investigate the stability of ohmic contacts to compound semiconductors, it is necessary to know the phase equilibria in the corresponding multi-component systems. We are currently studying the phase equilibria and thermophysical properties of several ternary systems which are of interest in view of the use of nickel, palladium and platinum as contact materials for GaSb and InSb compound semiconductors: Ga-Ni-Sb, In-Ni-Sb, Ga-Pd-Sb and Ga-Pt-Sb. Phase equilibria are investigated by thermal analyses, X-ray powder diffraction methods as well as electron microprobe analysis. Thermodynamic properties are derived from vapour pressure measurements using an isopiestic method. It is planned to combine all information on phase equilibria and thermochemistry for the ternary and the limiting binary systems to perform an optimization of the ternary systems by computer calculations using standard software.

    Materials undergo enhanced corrosion in the presence of oxidants in aqueous media. Usually, hydrogen gas or water soluble reducing agents are used for inhibiting corrosion. In the present study, the feasibility of using alternate reducing agents such as hydrazine, aqueous ammonia, and hydroxylamine that can stay in the liquid phase was investigated. A comparative study of corrosion behavior of the structural materials of the nuclear reactor viz. carbon steel (CS), stainless steel (SS-304 LN), monel-400 and incoloy-800 in the oxidizing and reducing conditions was also made. In nuclear industry, the presence of radiation field adds to the corrosion problems. The radiolysis products of water such as oxygen and hydrogen peroxide create an oxidizing environment that enhances the corrosion. Electrochemical studies at 90 °C showed that the reducing agents investigated were efficient in controlling corrosion processes in the presence of oxygen and hydrogen peroxide. Evaluation of thermal stability of hydrazine and its effect on corrosion potential of SS-304 LN were also investigated in the temperature range of 200–280 °C. The results showed that the thermal decomposition of hydrazine followed a first order kinetics. Besides, a change in electrochemical corrosion potential (ECP) was observed from −0.4 V (Vs SHE) to −0.67 V (Vs SHE) on addition of 5 ppm of hydrazine at 240 °C. Investigations were also made to understand the distribution behavior of hydrogen peroxide and hydrazine in water-steam phases and it was found that both the phases showed identical behavior. - Highlights: • Hydrazine was found to be a promising reducing agent for oxidant control. • In presence of hydrazine corrosion potential of SS304 LN was well below −230 mV. • SS304LN could be protected from IGSCC by hydrazine addition. • Thermal and radiation stability of hydrazine at 285 °C was found satisfactory.

    Full Text Available niversity courses in disciplines such as social work, family studies, humanities, and other areas often use classroom materials that contain traumatic material (Barlow & Becker-Blease, 2012. While many recommendations based on trauma theory exist for instructors at the university level, these are often made in the context of clinical training programs, rather than at the undergraduate level across disciplines. Furthermore, no organized model exists to aid instructors in developing a trauma-informed pedagogy for teaching courses on traumatic stress, violence, and other topics that may pose a risk for secondary traumatic stress in the classroom (Kostouros, 2008. This paper seeks to bridge the gap between trauma theory and implementation of sensitive content in classrooms of higher education, and presents a model of trauma-informed teaching that was developed in the context of an undergraduate trauma studies program. Implications and future directions for research in the area of trauma-informed university classrooms are discussed.

    The topic of climate change permeates all aspects of our society: the news, household debates, scientific conferences, etc. To provide students with accurate information about climate science and energy awareness, educators require scientifically and pedagogically robust teaching materials. To address this need, the NSF-funded Climate Literacy & Energy Awareness Network (CLEAN) Pathway has assembled a new peer-reviewed digital collection as part of the National Science Digital Library (NSDL) featuring teaching materials centered on climate and energy science for grades 6 through 16. The scope and framework of the collection is defined by the Essential Principles of Climate Science (CCSP 2009) and a set of energy awareness principles developed in the project. The collection provides trustworthy teaching materials on these socially relevant topics and prepares students to become responsible decision-makers. While a peer-review process is desirable for curriculum developer as well as collection builder to ensure quality, its implementation is non-trivial. We have designed a rigorous and transparent peer-review process for the CLEAN collection, and our experiences provide general guidelines that can be used to judge the quality of digital teaching materials across disciplines. Our multi-stage review process ensures that only resources with teaching goals relevant to developing climate literacy and energy awareness are considered. Each relevant resource is reviewed by two individuals to assess the i) scientific accuracy, ii) pedagogic effectiveness, and iii) usability/technical quality. A science review by an expert ensures the scientific quality and accuracy. Resources that pass all review steps are forwarded to a review panel of educators and scientists who make a final decision regarding inclusion of the materials in the CLEAN collection. Results from the first panel review show that about 20% (~100) of the resources that were initially considered for inclusion

    Highlights: • Anaerobic digestion and gasification are viable biomass conversion technologies. • GF-PEMFC system yields a 20% electric efficiency and 57% thermal efficiency. • AD-PEMFC system has a 9% electric efficiency and 13% thermal efficiency. • AD-PEMFC system has an efficient land-use. • GF-PEMFC system has a high CO_2 emissions offset factor. - Abstract: Biomass-fuelled polymer electrolyte membrane fuel cells (PEMFCs) offer a solution for replacing fossil fuel with hydrogen production. This paper uses simulation methods for investigating biomass-fuelled PEMFCs for different raw materials and conversion paths. For liquid and solid biomass, anaerobic digestion (AD) and gasification (GF), respectively, are relatively viable and developed conversion technologies. Therefore, the AD-PEMFC system and the GF-PEMFC system are simulated for residential applications in order to evaluate the performance of the biomass-fuelled PEMFC systems. The results of the evaluation show that renewable hydrogen-rich gas from manure or forest residues is usable for the PEMFCs and makes the fuel cell stack work in a stable manner. For 100 kWe generation, the GF-PEMFC system yields an excellent technical performance with a 20% electric efficiency and 57% thermal efficiency, whereas the AD-PEMFC system only has an 9% electric efficiency and 13% thermal efficiency due to the low efficiency of the anaerobic digester (AD) and the high internal heat consumption of the AD and the steam reformer (SR). Additionally, in this study, the environmental performances of the AD-PEMFC and the GF-PEMFC in terms of CO_2 emission offset and land-use efficiency are discussed.

    When visually impaired students attend regular high school, additional materials are necessary to help them understand physics concepts. The time for teachers to develop teaching materials for such students is scarce. Visually impaired students in regular high school physics classes often use a braille version of the physics textbook. Previously, we evaluated the physics learning environment of a blind high school student in a regular Dutch high school. In this research we evaluate the use of a revised braille textbook, relief drawings and 3D models. The research focussed on the topic of sound in grade 10.

These three requirements frame, and couple to, the challenge of plasma–material interaction (PMI) for fusion energy sciences. Present and planned tokamaks are not designed to simultaneously meet these criteria. A new and expanded set of dimensionless figures of merit for PMI have been developed. The key feature of the scaling is that the power flux across the last closed flux surface P/S ≃ 1 MW m −2 is to be held constant, while scaling the core volume-averaged density weakly with major radius, n ∼ R −2/7 . While complete similarity is not possible, this new “P/S” or “PMI” scaling provides similarity for the most critical reactor PMI issues, compatible with sufficient current drive efficiency for non-inductive steady-state core scenarios. A conceptual design is developed for Vulcan, a compact steady-state deuterium main-ion tokamak which implements the P/S scaling rules. A zero-dimensional core analysis is used to determine R = 1.2 m, with a conventional reactor aspect ratio R/a = 4.0, as the minimum feasible size for Vulcan. Scoping studies of innovative fusion technologies to support the Vulcan PMI mission were carried out for three critical areas: a high-temperature, helium-cooled vacuum vessel and divertor design; a demountable superconducting toroidal field magnet system; and a steady-state lower hybrid current drive system

    In the nineteenth and early twentieth centuries bones were an essential raw material for the German chemical industry, vital to the production of fertilizer, glue, gelatine, soap and other products. As most of this material was imported, the German school system during the "Third Reich" took the utilisation of bones as an example to illustrate the relevance of the four-year plan of 1936 and its policy of economic self-sufficiency. The school children were encouraged to collect bones from domestic sources and bring them to the collecting points in the schools. Several NS-institutions developed a variety of teaching aids and materials to support school education on this economically and politically important topic. Focussing on the example of bone-utilisation, this paper examines the messages and intentions of these educational materials. It also demonstrates how even apparently ideologically unbiased school subjects, such as chemistry, were instrumentalised for the political indoctrination of the pupils.

    In accordance with the European regulation for classification, labelling and packaging of substances and mixtures (CLP) as well as the criteria as set out in the Globally Harmonized System (GHS), fine fraction of crystalline silica (CS) has been classified as a specific target organ toxicity, the specific organ in this case being the lung. Generic cut-off values for products containing a fine fraction of CS trigger the need for a method for the quantification of the fine fraction of CS in bulk materials. This article describes the so-called SWeRF method, the size-weighted relevant fine fraction. The SWeRF method combines the particle size distribution of a powder with probability factors from the EN 481 standard and allows the relevant fine fraction of a material to be calculated. The SWeRF method has been validated with a number of industrial minerals. This will enable manufacturers and blenders to apply the CLP and GHS criteria for the classification of mineral products containing RCS a fine fraction of CS.

    The role of education all over the world is becoming more and more significant and requires an in depth study since the life of the people is advanced, expanded and complicated. Educators are once again asked to address problems which have arisen within their own society. Thus, the search for ways to improve quality of education is global especially in line with nuclear science and technology. One area of focus is that managing and promoting learning inside the classroom, how teacher's utilized instructional materials were such an issue. Indeed, qualifications and resources are not the only factors that influence teachers' effectiveness, equally important are teachers' motivation, commitment, resourcefulness, innovativeness and creativeness in dealing with instructional materials. Lack of these things will produce poor attendance and unprofessional attitudes towards students. This paper aims to present a proposal on the use of innovative teaching device from the sample photographs as a result of the experiment taken at Kyoto University Research Reactor Institute (KURRI) where samples were treated with gamma rays from a radioactive source 60 Co and lately exposed to photographic giving rise to understanding of photons emitted by radioactive material in a form of electromagnetic waves and later converted into visible light in a more authentic and simplified manners. As a consequent, this proposal was made to enhance teaching and encourage science teachers to exert great effort to develop instructional materials specifically in this area that requires the concretization of concepts which could not be detected by human senses.

    The aim of this study was to describe the analysis of mathematics teachers' learning on algebra function limit material based on teaching experience difference. The purpose of this study is to describe the analysis of mathematics teacher's learning on limit algebraic functions in terms of the differences of teaching experience. Learning analysis focused on Pedagogical Content Knowledge (PCK) of teachers in mathematics on limit algebraic functions related to the knowledge of pedagogy. PCK of teachers on limit algebraic function is a type of specialized knowledge for teachers on how to teach limit algebraic function that can be understood by students. Subjects are two high school mathematics teacher who has difference of teaching experience they are one Novice Teacher (NP) and one Experienced Teacher (ET). Data are collected through observation of learning in the class, videos of learning, and then analyzed using qualitative analysis. Teacher's knowledge of Pedagogic defined as a knowledge and understanding of teacher about planning and organizing of learning, and application of learning strategy. The research results showed that the Knowledge of Pedagogy on subject NT in mathematics learning on the material of limit function algebra showed that the subject NT tended to describe procedurally, without explaining the reasons why such steps were used, asking questions which tended to be monotonous not be guiding and digging deeper, and less varied in the use of learning strategies while subject ET gave limited guidance and opportunities to the students to find their own answers, exploit the potential of students to answer questions, provide an opportunity for students to interact and work in groups, and subject ET tended to combine conceptual and procedural explanation.

    The provision of the safeguards relevant reports and information in accordance with the comprehensive safeguards agreement (CSA) and the additional protocol (AP) is the basis for the IAEA safeguards. The government of Japan (Japan Safeguards Office, JSGO) has believed that the correct reports contribute to effective and efficient safeguards therefore the domestic quality assurance system for the reporting to the IAEA was already established at the time of the accession of the CSA in 1977. It consists of Code 10 interpretation (including the seminars for operators in Japan), SSAC's checks for syntax error, code and internal consistency (computer based consistency check between facilities) and the discussion with the IAEA on the facilities' measurement system for bulk-handling facilities, which contributes to the more accurate reports from operators. This spirit has been maintained for the entry into force of the AP. For example, questions and amplification from the IAEA will be taken into account the review of the AP declaration before sending to the IAEA and the open source information such as news article and scientific literature in Japanese is collected and translated into English, and the translated information is provided to the IAEA as the supplementary information, which may contribute to broadening the IAEA information source and to their comprehensive evaluation. The other safeguards relevant information, such as the mail-box information for SNRI at LEU fuel fabrication plants, is also checked by the JSGO's QC software before posting. The software was developed by JSGO and it checks data format, batch IDs, birth/death date, shipper/receiver information and material description code. This paper explains the history of the development of the Japanese quality assurance system regarding the reports and the safeguards relevant information to the IAEA. (author)

Más allá de la función instrumentalista que suele asignarse a los materiales didácticos, en el presente trabajo éstos se visualizan como construcciones discursivas que pueden facultar la apropiación del pensamiento basada en el desarrollo de habilidades lingüísticas que reflejen un discurso crítico ante los diferentes reclamos (problemas históricos a los que estudiantes se ven expuestos dentro y fuera del aula. Para tal propósito, se realiza una revisión conceptual-teórica sobre la importancia y la función que los materiales tienen en el proceso de enseñanza-aprendizaje de una lengua. Bajo una perspectiva crítica, se aborda el tema de los materiales didácticos y la construcción de la motivación así como el tema de ideología y materiales didácticos. Finalmente, se concluye que en el proceso de enseñanza-aprendizaje de una lengua, los materiales didácticos son reproductores y reproducciones discursivas e ideológicas de ciertas realidades que pueden ofrecer visiones de mundo basadas en los intereses de clases dominantes si no se abordan desde posturas críticas.Abstract: The aim of this article is to state the importance teaching materials have in developing a language teaching-learning process based on the principles of the critical thinking pedagogy. From this perspective, this work questions the traditional conceptions and notions related to instruments of access assigned to materials.

    Full Text Available Task-based language teaching has been widely used for language classroom. Using tasks as main activities, task-based materials was developed particularly for writing class. This article is intended to present the study of effectiveness of task-based materials in improving writing class for university. To accommodate the research purposes, mixed method approach was carried out by using quasi experimental research and content analysis of sentence complexity. The respondents were 210 students from writing classes as experiment and control with writing test as instrument. The results of data analysis showed that there were significant differences of writing skill to those who taught using developed task-based materials. Despite the fact that the score did not significantly differ on the aspect of writing mechanics, a developed task-based material has been proved to improve students’ writing skill in the aspect of format, content, organization and grammar. Moreover, the levels of lexical complexity and accuracy from the students whose materials use task-based design are higher than those who do not use it. Then, it can be drawn a conclusion that the use of developed task-based materials brings significant effects toward writing performance.

    In academic nuclear engineering departments, research and teaching in the specialized subdiscipline of nuclear materials is usually a one-person or at best a two-person operation. These subcritical sizes invariably result in inadequate overall representation of the many topics in nuclear materials in the research program of the department, although broader coverage of the field is possible in course offerings. Even in course-work, the full range of materials problems important in nuclear technology cannot be dealt with in detail because the small number of faculty involved restricts staffing to as little as a single summary course and generally no more than three courses in this specialty. The contents of the two nuclear materials courses taught at the University of California at Berkeley are listed. Materials research in most US nuclear engineering departments focuses on irradiation effects on metals, but at UC Berkeley, the principal interest is in the high-temperature materials chemistry of UO 2 fuel and Zircaloy cladding

    Full Text Available Pedagogical questions on whether recency or relevance of literary texts, and the importance of generic academic over discipline-based learning objectives as the core of literature instruction are increasingly becoming the interest of debates in senior high school education. Hence, this study determined the degree of importance of literary instruction in preparation for college education and workplace challenges as assessed by 38 Grade 11 students at Malvar Senior High School, Philippines during the school year 2016-2017. By employing the survey type of descriptive research with a self-made questionnaire, it was found out that the respondents assessed both recency and relevance as important consideration in selecting literary texts. They also perceived that discipline-based/work-oriented learning objectives, especially those that focus on honing their human relation skills, were relevant in preparing themselves for college education and workplace responsibilities. Moreover, the respondents preferred language-based activities that tend to provide the former opportunities and develop other complex skills which are important in tertiary education and workplace challenges. With these, revitalizing the literature instruction in the senior high school is highly recommended in this study.

    2017-01-01

    A computer-based modeling approach to teaching must be flexible because students and teachers have different skills and varying levels of preparation. Learning how to run the ``software du jour'' is not the objective for integrating computational physics material into the curriculum. Learning computational thinking, how to use computation and computer-based visualization to communicate ideas, how to design and build models, and how to use ready-to-run models to foster critical thinking is the objective. Our computational modeling approach to teaching is a research-proven pedagogy that predates computers. It attempts to enhance student achievement through the Modeling Cycle. This approach was pioneered by Robert Karplus and the SCIS Project in the 1960s and 70s and later extended by the Modeling Instruction Program led by Jane Jackson and David Hestenes at Arizona State University. This talk describes a no-cost open-source computational approach aligned with a Modeling Cycle pedagogy. Our tools, curricular material, and ready-to-run examples are freely available from the Open Source Physics Collection hosted on the AAPT-ComPADRE digital library. Examples will be presented.

    Full Text Available This study examined lexico-syntactic errors in selected textbooks written by Nigerians. Our focus was on the educated bilinguals (acrolect who acquired their primary, secondary and tertiary education in Nigeria and the selected textbooks were textbooks published by Vanity Publishers/Press. The participants (authors cut across the three major ethnic groups in Nigeria – Hausa, Igbo and Yoruba and the selection of the textbooks covered the major disciplines of study. We adopted the descriptive research design and specifically employed the survey method to accomplish the purpose of our exploratory research.  The lexico-syntactic errors in the selected textbooks were identified and classified into various categories. These errors were not different from those identified over the years in students’ essays and exam scripts. This buttressed our argument that students are merely the conveyor belt of errors contained in the teaching material and that we can analyse the students’ lexico-syntactic errors in tandem with errors contained in the material used in teaching.

    Full Text Available Learning a foreign language may be a challenge for most people due to differences in the form and structure between one’s mother tongue and a new one. However, there are some tools that facilitate the teaching and learning of a foreign language, for instance, new applications for digital devices, video blogs, educational platforms, and teaching materials. Therefore, this case study aims at understanding the role of teaching materials among beginners’ level students learning English as a foreign language. After conducting five non-participant classroom observations and nine semi-structured interviews, we found that the way the teacher implemented a pedagogical intervention by integrating the four language skills, promoting interactive learning through the use of online resources, and using the course book led to a global English teaching and learning process.

    In nuclear fusion devices the surfaces directly facing the plasma are irradiated with high energy fluxes. The most intense loads are deposited on the divertor located at the bottom of the plasma chamber, which has to withstand continuous heat loads with a power density of several MW . m{sup -2} as well as transient events. These are much shorter (in the millisecond and sub-millisecond regime) but deposit a higher power densities of a few GW . m{sup -2}. The search for materials that can survive to those severe loading conditions led to the choice of tungsten which possesses advantageous attributes such as a high melting point, high thermal conductivity, low thermal expansion and an acceptable activation rate. These properties made it an attractive and promising candidate as armor material for divertors of future fusion devices such as ITER and DEMO. For the DEMO divertor, conceptual studies on helium-cooled tungsten plasma-facing components were performed. The concept was realized and tested under DEMO specific cyclic thermal loads. The examination of the plasma-facing components by microstructural analyses before and after thermal loading enabled to determine the mechanisms for components failure. Among others, it clearly showed the impact of the tungsten grade and the thermal stress induced crack formation on the performance of the armor material and in general of the plasma-facing component under high heat loads. A tungsten qualification program was launched to study the behaviour of various tungsten grades, in particular the crack formation, under fusion relevant steady-state thermal loads. In total, seven commercially available materials from two industrial suppliers were investigated. As the material's thermal response is strongly related to its microstructure, this program comprised different material geometries and manufacturing technologies. It also included the utilization of an actively cooled specimen holder which has been designed to perform

    Despite many scholars' recommendations, science is often avoided during early childhood education. Among the reasons provided by early childhood teachers for the exclusion of science from their daily routines included science anxiety, low self-efficacy with respect to teaching science, lack of experience participating in science activities as students, or the notion that literacy and language are more important during the early years. In minority populations the problem is even greater due to identification of science with the `culture of. This article presents results from Ah Neen Dush, a sustained and transformative professional development program for Head Start teachers on an American Indian Reservation. The goal of the program is to support early childhood teachers in developing inquiry-based and culturally-relevant teaching practices. Through analysis of teachers' classroom practices, surveys and interviews, we explore changes in teachers' attitudes toward science and inquiry-based practices. Classroom observations were conducted using CLASS (Classroom assessment Scoring System), a tool used to evaluate the quality of classroom interactions. After 1 year of professional development teachers' attitudes were found to improve and after 2 years teachers classroom practices were more inquiry-based with statistically significant increases in CLASS observation scores.

In the first part of the paper, the IAQ regulations are summarized to highlight the second nation (i.e., Taiwan around the world in IAQ management by the law. In addition, the permissible exposure limits (PEL in Taiwan for airborne hazardous substances were first promulgated in 1974 to deal with occupational health issues in the workplace environment. In the second part of the paper, the developing status of the GBM in Taiwan is analyzed to unravel its connection with the Indoor Air Quality Management Act (IAQMA, promulgated on 23 November 2011. By the end of September 2017, a total of 645 GBM labels have been conferred, covering over 5000 green products. Due to the effectiveness of source control, the healthy GBM occupies most of the market, accounting for about 75%. The IAQMA, which took force in November 2012, is expected to significantly increase the use of healthy GBM in new building construction and remodeling, especially in low formaldehyde (HCHO/volatile organic compound (VOC-emitting products.

    Smoking-related illnesses are the leading causes of death among Hispanics/Latinos. Yet, there are few smoking cessation interventions targeted for this population. The goal of this study was to "transcreate" an existing, previously validated, English language self-help smoking cessation intervention, titled Forever Free ® : Stop Smoking for Good, for Spanish-speaking smokers. Rather than simply translating the materials, our transcreation process involved culturally adapting the intervention to enhance acceptability and receptivity of the information. We utilized a multiphase qualitative approach (focus groups and learner verification interviews) to develop a linguistically and culturally relevant intervention for the diverse sub-ethnic groups of Hispanic/Latino smokers. Focus group findings indicated a need to underscore several additional cultural characteristics and themes such as the need to address familism and unique stressors faced by immigrants and to provide information regarding nicotine replacement therapy. Learner verification findings indicated a need to further emphasize financial and social benefits of quitting smoking and to discuss how family and friends can support the quit attempt. These steps led to the development of a Spanish-language smoking cessation intervention titled, Libre del cigarillo, por mi familia y por mí: Guía para dejar de fumar, that is currently being tested in a national randomized controlled trial.

    Periphyton dominated by the cellulose-rich filamentous green alga Cladophora forms conspicuous growths along rocky marine and freshwater shorelines worldwide, providing habitat for diverse epibionts. Bacterial epibionts have been inferred to display diverse functions of biogeochemical significance: N-fixation and other redox reactions, phosphorus accumulation, and organic degradation. Here, we report taxonomic diversity of eukaryotic and prokaryotic epibionts and diversity of genes associated with materials cycling in a Cladophora metagenome sampled from Lake Mendota, Dane Co., WI, USA, during the growing season of 2012. A total of 1,060 distinct 16S, 173 18S, and 351 28S rRNA operational taxonomic units, from which >220 genera or species of bacteria (~60), protists (~80), fungi (6), and microscopic metazoa (~80), were distinguished with the use of reference databases. We inferred the presence of several algal taxa generally associated with marine systems and detected Jaoa, a freshwater periphytic ulvophyte previously thought endemic to China. We identified six distinct nifH gene sequences marking nitrogen fixation, >25 bacterial and eukaryotic cellulases relevant to sedimentary C-cycling and technological applications, and genes encoding enzymes in aerobic and anaerobic pathways for vitamin B12 biosynthesis. These results emphasize the importance of Cladophora in providing habitat for microscopic metazoa, fungi, protists, and bacteria that are often inconspicuous, yet play important roles in ecosystem biogeochemistry. © 2015 Phycological Society of America.

    The goal of the Modern Miracle Medical Machines project is to promote pre-med students' interest in physics by using the context of contemporary medical imaging. The X-ray medical imaging learning module will be a central part of this effort. To investigate students' transfer of learning in this context we have conducted a series of clinical and teaching interviews. In the latter interview, some of the proposed learning materials were used. The students brought to our discussion pieces of knowledge transferred from very different sources such as their own X-ray experiences, previous learning and the mass media. This transfer seems to result in more or less firm mental models which often are not always internally consistent or coherent

In order to take advantage of these opportunities, educators need quality topical resources related to current earth science events. The web has become an excellent vehicle for disseminating this type of resource. In response to the 2004 Indian Ocean Earthquake and to Hurricane Katrina's devastating impact on the US Gulf Coast, the On the Cutting Edge professional development program developed collections of visualizations for use in teaching. (serc.carleton.edu/NAGTWorkshops/visualization/collections/ tsunami.html,serc.carleton.edu/NAGTWorkshops/visualization/ collections/hurricanes.html). These sites are collections of links to visualizations and other materials that can support the efforts of faculty, teachers, and those engaged in public outreach. They bring together resources created by researchers, government agencies and respected media sources and organize them for easy use by educators. Links are selected to provide a variety of different types of visualizations (e.g photographic images, animations, satellite imagery) and to assist educators in teaching about the geologic event reported in the news, associated Earth science concepts, and related topics of high interest. The cited links are selected from quality sources and are reviewed by SERC staff before being included on the page. Geoscience educators are encouraged to recommend links and supporting materials and to comment on the available resources. In this way the collection becomes more complete and its quality is enhanced.. These sites have received substantial use (Tsunami - 77,000 visitors in the first 3 months, Hurricanes - 2500 visitors in the first week) indicating that in addition to use by educators, they are being used by the general public seeking information about the events. Thus they provide an effective mechanism for

    This article starts by providing a brief summary of relevance theory in information science in relation to the function theory of lexicography, explaining the different types of relevance, viz. objective system relevance and the subjective types of relevance, i.e. topical, cognitive, situational...... that is very important for lexicography as well as for information science, viz. functional relevance. Since all lexicographic work is ultimately aimed at satisfying users’ information needs, the article then discusses why the lexicographer should take note of all these types of relevance when planning a new...... dictionary project, identifying new tasks and responsibilities of the modern lexicographer. The article furthermore discusses how relevance theory impacts on teaching dictionary culture and reference skills. By integrating insights from lexicography and information science, the article contributes to new...

  10. Scholar-activating teaching materials on quantum physics. Pt. 3. Foundations of atomic physics

    International Nuclear Information System (INIS)

    Huebel, Horst

    2010-01-01

    Traditionally in the center of the interest on quantum physics referring to schools the question lies, whether electrons or photons are now particles or waves, a question, which is often characterized by the phrase ''wave-particle dualism'', which notoriously not exists in its original meaning. Against that by the author - on the base of important preparatory works of Kueblbeck and Mueller - a new concept of quantum physics for the school was proposed, which puts ''basic facts'' in the foreground, comparable with the Kueblbeck-Mueller ''characteristic features''. The ''basic facts'' are similar to axioms of quantum physics, by means of them a large number of experiments and phenomena can be ''explained'' at least qualitatively - in a heuristic way -. Instead of the so-called ''wave-particle dualism'' uncertainty and complementarity are put in the foreground. The new concept is in the Internet under http://www.forphys.de extensively presented with many further materials. In the partial volumes of this publication manifold and carefully elaborated teaching materials are presented, by which scholars can get themselves the partial set of quantum physics referring to schools by different methods like learning at stations, short referates, Internet-research, group puzzle, the query-sheet or the card-index method etc. In the present 3. part materials are prepared, by which scholars can get foundations of atomic physics and interpret in the sense of the ''basic facts or quantum physics''. Here deals it thus with discrete energy levels, the linear potential box, with atomic models, the atomic structure, the tunnel effect, and - because curricula it often require - also with the Schroedinger equation. The materials can also be usefully applied in other concepts.

    Active Pharmaceutical Ingredients (API) raw material variability is not always thoroughly considered during pharmaceutical process development, mainly due to low quantities of drug substance available. However, synthesis, crystallization routes and production sites evolve during product development and product life cycle leading to changes in physical material attributes which can potentially affect their processability. Recent literature highlights the need for a global approach to understand the link between material synthesis, material variability, process and product quality. The study described in this article aims at explaining the raw material variability of an API using extensive material characterization on a restricted number of representative batches using multivariate data analysis. It is part of a larger investigation trying to link the API drug substance manufacturing process, the resulting physical API raw material attributes and the drug product continuous manufacturing process. Eight API batches produced using different synthetic routes, crystallization, drying, delumping processes and processing equipment were characterized, extensively. Seventeen properties from seven characterization techniques were retained for further analysis using Principal Component Analysis (PCA). Three principal components (PCs) were sufficient to explain 92.9% of the API raw material variability. The first PC was related to crystal length, agglomerate size and fraction, flowability and electrostatic charging. The second PC was driven by the span of the particle size distribution and the agglomerates strength. The third PC was related to surface energy. Additionally, the PCA allowed to summarize the API batch-to-batch variability in only three PCs which can be used in future drug product development studies to quantitatively evaluate the impact of the API raw material variability upon the drug product process. The approach described in this article could be applied to any

    The study aimed to find out the effectiveness of using Strategic Intervention Materials (SIMs) as an innovative teaching practice in managing large Grade Eight Science classes to raise the performance of the students in terms of science process skills development and mastery of science concepts. Utilizing experimental research design with two groups of participants, which were purposefully chosen, it was obtained that there existed a significant difference in the performance of the experimental and control groups based on actual class observation and written tests on science process skills with a p-value of 0.0360 in favor of the experimental class. Further, results of written pre-test and post-test on science concepts showed that the experimental group with the mean of 24.325 (SD =3.82) performed better than the control group with the mean of 20.58 (SD =4.94), with a registered p-value of 0.00039. Therefore, the use of SIMs significantly contributed to the mastery of science concepts and the development of science process skills. Based on the findings, the following recommendations are offered: 1. that grade eight science teachers should use or adopt the SIMs used in this study to improve their students' performance; 2. training-workshop on developing SIMs must be conducted to help teachers develop SIMs to be used in their classes; 3. school administrators must allocate funds for the development and reproduction of SIMs to be used by the students in their school; and 4. every division should have a repository of SIMs for easy access of the teachers in the entire division.

    Compositionally homogeneous mixed-material layers of Be and W, ∼2 μm thick, and of various W contents (spanning 0–100 at.% W), are produced by thermionic vacuum arc deposition. The layers are exposed to low energy (∼50 eV), high ion flux (6–8 × 10 22 m −2 s −1 ) D 2 -0.1He (10% He) mixed species plasma at 473 K and 1073 K to simulate ITER-like first wall and divertor plasma-material interaction. Surface morphological and compositional analysis is conducted prior and subsequent to plasma exposure. The action of the plasma produces almost complete depletion of Be from the near surface, and this is found regardless of the exposure temperature or initial composition. In the exposure case of 473 K, thermal desorption spectrometry reveals decreased D retention in W rich compositions compared to similar exposure in D 2 plasma without He, but no discernable difference is noted in Be rich compositions. At 1073 K, surface enrichment in W, by depletion of the Be, results in He induced W “fuzz” structures for all Be-W compositions explored.

  2. Evaluation of some procedures relevant to the determination of trace elemental components in biological materials by destructive neutron activation analysis

    1979-01-01

    The development of a simplified procedure for the analysis of biological materials by destructive neutron activation analysis (DNAA) is described. The sample manipulations preceding gamma ray assay were investigated as five specific stages of processing: (1) pre-irradiation treatment; (2) sample irradiation; (3) removal of the organic matrix; (4) removal of interfering radioactivities; and (5) concentration and separation of analyte activities. Each stage was evaluated with respect to susceptibility to sample contamination, loss of trace elemental components, and compatibility with other operations in the overall DNAA procedures. A complete DNAA procedure was proposed and evaluated for the analysis of standard bovine liver and blood samples. The DNAA system was effective for the determination of As, Cu, Fe, Hg, Mo, Rb, Sb, Se, and Zn without yield determinations and with a minimum turn-around time of approximately 3 days

    Containment of spent nuclear fuel and vitrified forms of high level nuclear waste require use of materials that are highly corrosion resistant to all of the anticipated environmental scenarios that can occur in a geological repository. Ni-Cr-Mo Alloy 22 (UNS N60622) is proposed for the corrosion resistant outer barrier of a two-layer waste package container at the potential repository site at Yucca Mountain. A range of water compositions that may contact the outer barrier is under consideration, and a testing program is underway to characterize the forms of corrosion and to quantify the corrosion rates. Results from the testing support models for long term prediction of the performance of the container. Results obtained to date indicate a very low general corrosion rate for Alloy 22 and very high resistance to all forms of localized and environmentally assisted cracking in environments tested to date

    Purpose: Magnetic resonance imaging (MRI) is capable of providing valuable real-time feedback during medical procedures, partly due to the excellent soft-tissue contrast available. Several technical hurdles still exist to seamless integration of medical devices with MRI due to incompatibility of most conventional devices with this imaging modality. In this study, the effect of local perturbations in the magnetic field caused by the magnetization of medical devices was examined using finite element analysis modeling. As an example, the influence of the geometric and material characteristics of a transurethral high-intensity ultrasound applicator on temperature measurements using proton resonance frequency (PRF)-shift thermometry was investigated. Methods: The effect of local perturbations in the magnetic field, caused by the magnetization of medical device components, was examined using finite element analysis modeling. The thermometry artifact generated by a transurethral ultrasound applicator was simulated, and these results were validated against analytic models and scans of an applicator in a phantom. Several parameters were then varied to identify which most strongly impacted the level of simulated thermometry artifact, which varies as the applicator moves over the course of an ablative high-intensity ultrasound treatment. Results: Key design parameters identified as having a strong influence on the magnitude of thermometry artifact included the susceptibility of materials and their volume. The location of components was also important, particularly when positioned to maximize symmetry of the device. Finally, the location of component edges and the inclination of the device relative to the magnetic field were also found to be important factors. Conclusions: Previous design strategies to minimize thermometry artifact were validated, and novel design strategies were identified that substantially reduce PRF-shift thermometry artifacts for a variety of device

    2018-04-01

    Full Text Available In the world of education, a delivery of stories is one of the effective strategies to deliver educational materials to children or learners. As the matter of facts, sometimes the stories told to the children or learners are taken from untruthful sources or fairy tales that will cause a delusion in the child's mind. It is important for parents or educators to convey valued stories coming from the teachings of Islamic values, such as the stories of the previous people delivered by the Prophet Mohammad through his traditions. The purpose of this study is to examine the editorial accounts of the story of the prophet Abraham and Sarah with the zholim King, and to know the understanding of the hadith and the educational analysis associated with this hadith. To obtain the information on the hadith about the story, the researcher uses a takhrîj hadith method, in as much as, it was found there are various relevant hadiths of the Prophet Muhammad related to the story. These hadiths have been analyzed for their historical qualities and linked them with Islamic education materials.

  8. Effects of testing on subsequent re-encoding and long-term forgetting of action-relevant materials: On the influence of recall type.

    Testing one's memory of previously studied information reduces the rate of forgetting, compared to restudy. However, little is known about how this direct testing effect applies to action phrases (e.g., "wash the car") - a learning material relevant to everyday memory. As action phrases consist of two different components, a verb (e.g., "wash") and a noun (e.g., "car"), testing can either be implemented as noun-cued recall of verbs or verb-cued recall of nouns, which may differently affect later memory performance. In the present study, we investigated the effect of testing for these two recall types, using verbally encoded action phrases as learning materials. Results showed that repeated study-test practice, compared to repeated study-restudy practice, decreased the forgetting rate across 1 week to a similar degree for both noun-cued and verb-cued recall types. However, noun-cued recall of verbs initiated more new subsequent learning during the first restudy, compared to verb-cued recall of nouns. The study provides evidence that testing has benefits on both subsequent restudy and long-term retention of action-relevant materials, but that these benefits are differently expressed with testing via noun-cued versus verb-cued recall. © 2015 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

  9. Potentiality of Yeasts in the Direct Conversion of Starchy Materials to Ethanol and Its Relevance in the New Millennium

    Science.gov (United States)

    Reddy, L. V. A.; Reddy, O. V. S.; Basappa, S. C.

    In recent years, the use of renewable and abundantly available starchy and cellulosic materials for industrial production of ethanol is gaining importance, in view of the fact, that ethanol is one of the most prospective future motor fuels, that can be expected to replace fossil fuels, which are fast depleting in the world scenario. Although, the starch and the starchy substrates could be converted successfully to ethanol on industrial scales by the use of commercial amylolytic enzymes and yeast fermentation, the cost of production is rather very high. This is mainly due to the non-enzymatic and enzymatic conversion (gelatinization, liquefaction and saccharification) of starch to sugars, which costs around 20 % of the cost of production of ethanol from starch. In this context, the use of amylolytic yeasts, that can directly convert starch to ethanol by a single step, are potentially suited to reduce the cost of production of ethanol from starch. Research advances made in this direction have shown encouraging results, both in terms of identifying the potentially suited yeasts for the purpose and also their economic ethanol yields. This chapter focuses on the types of starch and starchy substrates and their digestion to fermentable sugars, optimization of fermentation conditions to ethanol from starch, factors that affect starch fermentation, potential amylolytic yeasts which can directly convert starch to ethanol, genetic improvement of these yeasts for better conversion efficiency and their future economic prospects in the new millennium.

    This paper summarizes PF-160 Dual Plasma Focus (DuPF) numerical experiments using the Lee Model code and preliminary 3D design drawings using SolidWorks software. This DuPF consists of two interchangeable electrodes enabling it to be optimized for both Slow Pinch Mode (SFM) and Fast Pinch Mode (FFM); the latter using a speed factor (SF) of 90 kA cm-1 Torr-0.5 for FFM in deuterium [S Lee et al, IEEE Trans Plasma Science 24, 1101-1105 (1996)]; and the former with SF of less than half that value for SFM. Starting with available 6 × 450 µF capacitors rated at 11kV (10% reversal), numerical experiments indicate safe operation at 9 kV, 6 Torr deuterium with FFM anode of 5 cm radius; producing intense ion beam and streaming plasma pulses which would be useful for studies of potential fusion reactor wall materials. On the other hand operating at 5 kV, 10 Torr deuterium with SFM anode of 10 cm radius leads to long-duration, uniform large-area flow which could be more suitable for synthesis of nano-materials. The dual plasma focus design is illustrated here with two figures showing FFM and SFM electrodes. (author)

    2012-08-01

    Full Text Available Animation gives a different perception on what is being visually presented. Research has shown that students are likely to understand what is being taught from the combination of animation and text than just with text. Students easily understand scientific concepts in narrative and animated forms. Data structure is a way of storing and arranging data. The efficacy of searching these stored data is very important, so is it vital that they are stored with the right algorithm. This paper presents animations designed to support teaching in computer education. Our main focus is to present controlled animated instructional materials in teaching topics in data structures. We have created three scientifically animated instructional materials in data structures consisting of the Stacks, Queues and Trees. These scientific spheres have been chosen to demonstrate the basic ideas of this work, because of its simplicity in representing the animations. We hope to develop reasonable sets of instructional material of different subject areas that will be stored in a database repository. These are intended to be delivered to students through an e-learning website and/or Mobile phones to support them with additional learning opportunities.

    A part of the waste materials arising in iron and steel manufacture is utilised physically, either internally for the recovery of iron or externally for the production of cement and nonferrous metals. Most of these materials can be used without prior processing. Iron and steel-relevant waste materials which at present are still landfilled or disposed of as hazardous wastes are not immediately suitable for physical recycling as secondary raw material. These waste materials have to be processed without exception before they can be used again in the existing steel and iron manufacturing plants. The results of the authors` own studies have clearly shown that the cupola furnace is suited for the use of a wide variety of waste materials. [Deutsch] Ein Teil der bei der Eisen- und Stahlerzeugung anfallenden Abfallstoffe werden entweder intern zur Rueckgewinnung des Eisens oder extern in der Zement- bzw. Nichteisenmetallgewinnung stofflich verwertet. Dabei handelt es sich ueberwiegend um Materialien, die ohne weitere Aufbereitung verwertbar sind. Die bislang noch deponierten oder als Sonderabfall entsorgten eisen- und stahlrelevanten Abfallstoffe sind ohne weiteres als Sekundaerrohstoff nicht stofflich verwertbar. Die Aufarbeitung dieser Abfallstoffe ist fuer den Wiedereinsatz in den vorhandenen Anlagen zur Gewinnung von Eisen und Stahl zwingend erforderlich. Die Ergebnisse der eigenen Untersuchungen haben klar gezeigt, dass der Kupolofen fuer die Nutzung einer grossen Vielfalt an Abfallstoffen geeignet ist. Zur Erhoehung der spezifischen Einsatzmenge an eisen- und stahlrelevanten Abfallstoffen untersuchen wir derzeit den Einsatz von oxidischen Materialien als sogenannte selbstgaengige Briketts zusammen mit den ueblichen Eisentraegern fuer die Erzeugung von fluessigem Giessereieisen. Selbstgaengig heisst hierbei, dass der Reduktionskohlenstoff und auch die notwendigen Legierungselemente insbesondere Silizium als SiC in den Briketts eingebunden werden. Fuer die Aufbereitung

    Matsumoto, Yuki; Sakaki, Kei; Sakaki, Mamoru

    2017-05-01

    A simple handmade motor is a commonly used teaching aid for explaining the theory of the DC motor in science classes around the world. Kits that can be used by children to craft a simple motor are commercially available, and videos of assembling these motors are easily found on the internet. Although the design of this motor is simple, it is unipolar, meaning that the rotor consists of a single dipole. Thus, the Lorentz force acts only on one side of the coil per revolution. This decreases the energy conversion efficiency and requires the learners to turn the rotor using their hands in order to initiate rotation.

  8. What Is Construed as Relevant Knowledge in Physics Teaching? Similarities and Differences in How Knowledge and Power Are Staged in Three Lower Secondary Classrooms

    Lidar, Malena; Danielsson, Anna T.; Berge, Maria

    2018-05-01

    The content that is privileged in teaching has consequences for what the students are given the opportunity to learn and can thus be regarded as an aspect of power. We analyse power aspects in the teaching of physics by identifying actions that guide or direct other people's actions, and then analyse similarities and differences in different classrooms in terms of how governance is staged and what potential consequences this can have. The analyses are made on data from classroom activities, documented through video recordings and field notes, in three lower secondary schools in Y8 and Y9, respectively. At first glance, teachers from all three schools adhere to a traditional interpretation of a physics curriculum. But a more in-depth analysis shows that the students in the different classrooms are given quite dissimilar opportunities to participate in teaching and create relationships with the content. What appears to be a desirable way of acting offers different conditions for meaning-making. In an increasingly individualised society where people are expected to be active, reflective and make choices for their own personal good, the students in these three classrooms are offered very different conditions to practice and learn to take part in knowledge-making, connect physics content to their everyday life and exercise informed citizenship.

This study was to assess the efficacy of using ELT research papers as authentic materials in teaching research-based article writing. This study was aimed at revealing whether or not there is a significant difference in students’ writing skill in terms of ELT research paper writing between the students who were taught by using ELT research papers as authentic materials and those who were taught by using textbook materials provided by the faculty. This study belongs to a quasi-experimental study with an experimental and control group pretest-posttest design. The population of this study was 75 students from the fourth semester of English Education Study Program of IKIP PGRI Bojonegoro, East Java, Indonesia. The sample was selected through cluster random sampling and consisted of 50 students that were divided into two groups. The instrument used to collect the data was a writing test. Consequently, normality and homogeneity of the data were tested. A t-test was used to compare the mean of the two groups. The hypothesis was designed and tested at 0.05 level of significance. The results revealed that there is a significant difference in students’ academic writing skill between the students who were taught by using the ELT research papers as authentic materials and those who were taught by using textbook materials. The t-test revealed that t-value is higher than t-table (6.07>2.01. Therefore it is concluded that the authentic instructional materials could significantly improve students’ academic writing skill.

    An integrated program of batch sorption experiments and mathematical modeling has been carried out to study the sorption of plutonium and americium on a series of repository, backfill and geological materials relevant to the JNFL low-level radioactive waste repository at Rokkasho-Mura. The sorption of plutonium and americium on samples of concrete, mortar, sand/bentonite, tuff, sandstone and cover soil has been investigated. In addition, specimens of bitumen, cation and anion exchange resins, and polyester were chemically degraded. The resulting degradation product solutions, alongside solutions of humic and isosaccharinic acids were used to study the effects on plutonium sorption onto concrete, sand/bentonite and sandstone. The sorption behavior of plutonium and americium has been modeled using the geochemical speciation program HARPHRQ in conjunction with the HATCHES database

    1987-12-01

    This report discusses the performance of candidate metallic materials envisioned for fabricating waste package containers for long-term disposal at a possible geological repository at Yucca Mountain, Nevada. Candidate materials include austenitic iron-base to nickel-base alloy (AISI 304L, AISI 316L, and Alloy 825), high-purity copper (CDA 102), and copper-base alloys (CDA 613 and CDA 715). Possible degradation modes affecting these container materials are identified in the context of anticipated environmental conditions at the repository site. Low-temperature oxidation is the dominant degradation mode over most of the time period of concern (minimum of 300 yr to a maximum of 1000 yr after repository closure), but various forms of aqueous corrosion will occur when water infiltrates into the near-package environment. The results of three years of experimental work in different repository-relevant environments are presented. Much of the work was performed in water taken from Well J-13, located near the repository, and some of the experiments included gamma irradiation of the water or vapor environment. The influence of metallurgical effects on the corrosion and oxidation resistance of the material is reviewed; these effects result from container fabrication, welding, and long-term aging at moderately elevated temperatures in the repository. The report indicates the need for mechanisms to understand the physical/chemical reactions that determine the nature and rate of the different degradation modes, and the subsequent need for models based on these mechanisms for projecting the long-term performance of the container from comparatively short-term laboratory data. 91 refs., 17 figs., 16 tabs

    The nebulous term phase-change material (PCM) simply refers to any substance that has a large heat of fusion and a sharp melting point. PCMs have been used for many years in commercial applications, mainly for heat management purposes. However, these fascinating materials have recently been rediscovered and applied to a broad range of technologies, such as smart drug delivery, information storage, barcoding, and detection. With the hope of kindling interest in this incredibly versatile range of materials, this Review presents an array of aspects related to the compositions, preparations, and emerging applications of PCMs. © 2014 WILEY-VCH Verlag GmbH & Co.

    2014-12-01

    The goal of this multi-institutional collaboration was to develop an innovative, locally relevant ethics curriculum for nurses in Botswana. Nurses in Botswana face ethical challenges that are compounded by lack of resources, pressures to handle tasks beyond training or professional levels, workplace stress and professional isolation. Capacity to teach nursing ethics in the classroom and in professional practice settings has been limited. A pilot curriculum, including cases set in local contexts, was tested with nursing faculty in Botswana in 2012. Thirty-three per cent of the faculty members indicated they would be more comfortable teaching ethics. A substantial number of faculty members were more likely to introduce the International Council of Nurses Code of Ethics in teaching, practice and mentoring as a result of the training. Based on evaluation data, curricular materials were developed using the Code and the regulatory requirements for nursing practice in Botswana. A web-based repository of sample lectures, discussion cases and evaluation rubrics was created to support the use of the materials. A new master degree course, Nursing Ethics in Practice, has been proposed for fall 2015 at the University of Botswana. The modular nature of the materials and the availability of cases set within the context of clinical nurse practice in Botswana make them readily adaptable to various student academic levels and continuing professional development programmes. The ICN Code of Ethics for Nursing is a valuable teaching tool in developing countries when taught using locally relevant case materials and problem-based teaching methods. The approach used in the development of a locally relevant nursing ethics curriculum in Botswana can serve as a model for nursing education and continuing professional development programmes in other sub-Saharan African countries to enhance use of the ICN Code of Ethics in nursing practice. © 2014 International Council of Nurses.

  19. Strategies for Teaching Astronomy

    Science.gov (United States)

    Bennett, J.

    2000-12-01

    No matter whether you are teaching school children, undergraduates, or colleagues, a few key strategies are always useful. I will present and give examples for the following five key strategies for teaching astronomy. 1. Provide a Contextual Framework: It is much easier to learn new facts or concepts if they can be ``binned" into some kind of pre-existing mental framework. Unless your listeners are already familiar with the basic ideas of modern astronomy (such as the hierarchy of structure in the universe, the scale of the universe, and the origin of the universe), you must provide this before going into the details of how we've developed this modern picture through history. 2. Create Conditions for Conceptual Change: Many people hold misconceptions about astronomical ideas. Therefore we cannot teach them the correct ideas unless we first help them unlearn their prior misconceptions. 3. Make the Material Relevant: It's human nature to be more interested in subjects that seem relevant to our lives. Therefore we must always show students the many connections between astronomy and their personal concerns, such as emphasizing how we are ``star stuff" (in the words of Carl Sagan), how studying other planets helps us understand our own, and so on. 4. Limit Use of Jargon: The number of new terms in many introductory astronomy books is larger than the number of words taught in many first courses in foreign language. This means the books are essentially teaching astronomy in a foreign language, which is a clear recipe for failure. We must find ways to replace jargon with plain language. 5. Challenge Your Students: Don't dumb your teaching down; by and large, students will rise to meet your expectations, as long as you follow the other strategies and practice good teaching.

  4. A phenomenological case study concerning science teacher educators' beliefs and teaching practices about culturally relevant pedagogy and preparing K-12 science teachers to engage African American students in K-12 science

    Science.gov (United States)

    Underwood, Janice Bell

    Due to the rising diversity in today's schools, science teacher educators (STEs) suggest that K-12 teachers must be uniquely prepared to engage these students in science classrooms. Yet, in light of the increasing white-black science achievement gap, it is unclear how STEs prepare preservice teachers to engage diverse students, and African Americans in particular. Therefore, the purpose of this study was to find out how STEs prepare preservice teachers to engage African American students in K-12 science. Thus, using the culturally relevant pedagogy (CRP) framework, this phenomenological case study explored beliefs about culturally relevant science teaching and the influence of reported beliefs and experiences related to race on STEs' teaching practices. In the first phase, STE's in a mid-Atlantic state were invited to participate in an electronic survey. In the second phase, four participants, who were identified as exemplars, were selected from the survey to participate in three semi-structured interviews. The data revealed that STEs were more familiar with culturally responsive pedagogy (CResP) in the context of their post-secondary classrooms as opposed to CRP. Further, most of the participants in part one and two described modeling conventional ways they prepare their preservice teachers to engage K-12 students, who represent all types of diversity, without singling out any specific race. Lastly, many of the STEs' in this study reported formative experiences related to race and beliefs in various manifestations of racism have impacted their teaching beliefs and practices. The findings of this study suggest STEs do not have a genuine understanding of the differences between CRP and CResP and by in large embrace CResP principles. Secondly, in regards to preparing preservice teachers to engage African American students in science, the participants in this study seemed to articulate the need for ideological change, but were unable to demonstrate pedagogical changes

    Full text: This paper points out a summary of the relevant aspects related to the transport of radioactive material in Argentina treated only from a regulatory focussing, it is to say from the point of view of its competent authority of application the Nuclear Regulatory Authority (in Spanish, the Autoridad Regulatoria Nuclear, ARN). Firstly, it is introduced the legal and regulatory framework applicable to the transport of radioactive material and the corresponding authorities involved (ARN, Secretary of Transport, and the Argentine Air Force, Naval Prefecture and Navy). Then, it is presented a schedule of the main characteristics of the shipments of radioactive material used in both the nuclear cycle and in medicine, industry and research, and an average of the shipments annually transported in Argentina. Further on the paper briefly analyses the ARN sources and the way in which it performs the compliance assurance with the in-force transport regulations in the country. Particularly, it is explained certain main tools used by the compliance system, as for example, transport notice, data base, licensing of certain design packages, shipments and materials, inspection and audits, and fees and sanctions regimes. On the other hand, it is mentioned the Argentine experience in the development, licensing, manufacture and use of domestic designs of Type B(U) packages and special form radioactive material (cobalt 60 and iridium 192 sealed sources). Moreover, it is concisely described test facilities available in the country necessary to perform the mentioned designs. Finally, the paper shortly describes the ARN main transport activities exclusively concerning the relationship with other national organisations (Federal Police, Gendarmerie, Naval Prefecture and Argentine Institute of Material Rationalisation, in Spanish Instituto Argentino de Racionalizacion de Materiales - IRAM) and with regional and inter regional organisations (South American Common Market, in Spanish

    This Safety Series book should be considered as a technical guide aimed at the users of radioactive materials and the appropriate local and national authorities. It does not represent a single solution to the problems involved but rather draws the outlines of the plans and procedures that have to be developed in order to mitigate the consequences of an accident, should one occur. The preparation of local and national plans should follow the technical recommendations provided in this publication, with due consideration given to local factors which might vary from country to country (e.g. governmental systems, local legislation, quantities of radioactive materials involved). Several types of accidents are described, together with their possible radiological consequences. The basic principles of the protective measures that should be applied are discussed, and the principles of emergency planning and the measures needed to maintain preparedness for an operational response to an accident are outlined

    The aims of this cross-sectional study were to determine the prevalence of occupational accidents with exposure to biological material among undergraduate students of dentistry and to estimate potential risk factors associated with exposure to blood. Data were collected through a self-administered questionnaire (86.4 percent return rate), which was completed by a sample of 286 undergraduate dental students (mean age 22.4 +/-2.4 years). The students were enrolled in the clinical component of the curriculum, which corresponds to the final six semesters of study. Descriptive, bivariate, simple logistic regression and multiple logistic regression (Forward Stepwise Procedure) analyses were performed. The level of statistical significance was set at 5 percent. Percutaneous and mucous exposures to potentially infectious biological material were reported by 102 individuals (35.6 percent); 26.8 percent reported the occurrence of multiple episodes of exposure. The logistic regression analyses revealed that the incomplete use of individual protection equipment (OR=3.7; 95 percent CI 1.5-9.3), disciplines where surgical procedures are carried out (OR=16.3; 95 percent CI 7.1-37.2), and handling sharp instruments (OR=4.4; 95 percent CI 2.1-9.1), more specifically, hollow-bore needles (OR=6.8; 95 percent CI 2.1-19.0), were independently associated with exposure to blood. Policies of reviewing the procedures during clinical practice are recommended in order to reduce occupational exposure.

  13. Scholar-activating teaching materials for quantum physics. Pt. 2. Basic facts of quantum physics and heuristic methods

    International Nuclear Information System (INIS)

    Huebel, Horst

    2010-01-01

    Traditionally in the center of interest on quantum physics referring to schools the question lies, whether electrons and photons are now particles or waves, a question, which is often characterized by the phrase ''wave-particle dualism'', which notoriously not exists in its original meaning. Against that by the author - basing on important preparatory works of Kueblbeck and Mueller - a new concept for the treatment of quantum physics for the school was proposed, which puts ''basic facts'' in the foreground, comparable with the Kueblbeck-Mueller ''characteristic features''. The ''basic facts'' are similar to axioms of quantum physics, by means of which a large number of experiments and phenomena can be ''explained'' at least qualitatively - in a heuristic way -. Instead of the so-called ''wave-particle dualism'' here uncertainty and complementarity are put in the foreground. The new concept is in the Internet under http://www.forphys.de extensively presented with many further materials. In the partial volumes of this publication manifold and carefully elaborated teaching materials are presented, by means of which scholars can get themselves the partial set of quantum physics referring to schools by different methods like learn at stations, short referates, Internet research, group puzzle, the query-sheet or the card-index method etc. In the present 2. part materials for the ''basic facts'' of quantum physics are prepared, by which also modern experiments can be interpreted. Here deals it with the getting of knowledge and application of the ''basic Facts''. This pursues also by real scholar experiments, simulations and analogy tests. The scholars obtain so more simply than generally a deeper insight in quantum physics.

    Ganz, Jennifer B; Flores, Margaret M

    2009-01-01

    Students with autism spectrum disorders (ASD) frequently demonstrate language delays (American Psychiatric Association 2000). This study investigated the effects of a Direct Instruction (DI) language program implemented with elementary students with ASD. There is little research in the area of DI as a language intervention for students with ASD. This study examined the effectiveness of DI with regard to students' oral language skills, specifically the identification of materials of which objects were made. A single-subject changing criterion design was employed. A functional relation between DI and oral language skills was demonstrated through replication of skill increase over three criterion changes and across three students. The results and their implications are discussed further.

    Full Text Available "The relevance of habitus, social origin and the mechanisms of exclusion as applied by the university system has often been discussed in current research. It has been stated that opportunities of students are impaired by field-of-study orientations and drop-out rates. In contrast to this, the aspect how university teachers can practically deal with this knowledge is less elaborated. In view of this, this article presents methods of how learner-oriented approaches, with special reference to the heterogeneity of student milieus, can be implemented in teaching sociology. On the basis of reviewing theoretical approaches and recent empirical data, this article points out a what data are relevant for the operationalisation of learner oriented didactics,b what concrete problems might occur in the teacher-student-relationship and c what techniques are to be applied by sociology teachers in handling classroom problems. The results demonstrate that teaching methods which adequately respond to heterogeneity within the culture of sociology departments are imperative and available. Still, to establish equal opportunities, a more practical turn in a hitherto predominantly theoretical discussion is clearly needed.Chancenungleichheit durch Passungsdifferenzen unterschiedlicher sozialer Milieus zum Hochschulsystem ist schon häufig theoretisch diskutiert worden.

    Natural radionuclides are part of the human environment and of the raw materials used. Technical processes may cause their accumulation in residues, and the result will be so-called NORM materials (Naturally occurring radioactive material). The amended Radiation Protection Ordinance (StrlSchV 2001) specifies how the public should be protected, but there are also residues dating back before the issuing of the StrlSchV 2001, the so-called NORM residues. The project intended to assess the risks resulting from these residues. It comprises four parts. Part 1 was for clarification of the radiological relevance of NORM residues and for the development of concepts to detect them. The criterion for their radiological relevance was their activity per mass unit and the material volume accumulated through the centuries. The former was calculated from a wide bibliographic search in the relevant literature on radiation protection, while the mass volume was obtained by a detailed historical search of the consumption of materials that may leave NORM residues. These are, in particular, residues from coal and ore mining and processing. To identify concrete sites, relevant data sources were identified, and a concept for identification of concrete NORM residues was developed on this basis. (orig.) [de

    Sustainability is emerging as a central theme for teaching about the environment, whether it be from the perspective of science, economics, or society. The Systems, Society, Sustainability and the Geosciences workshop provided 48 undergraduate faculty from 46 institutions a forum to discuss the challenges and possibilities for integrating geoscience concepts with a range of other disciplines to teach about the fundamentals of sustainability. Participants from community college to doctorate-granting universities had expertise that included geosciences, agriculture, biological sciences, business, chemistry, economics, ethnic studies, engineering, environmental studies, environmental education, geography, history, industrial technology, landscape design, philosophy, physics, and political science. The workshop modeled a range of teaching strategies that encouraged participants to network and collaborate, share successful strategies and materials for teaching sustainability, and identify opportunities for the development of new curricular materials that will have a major impact on the integration of geosciences into the teaching of sustainability. The workshop design provided participants an opportunity to reflect upon their teaching, learning, and curriculum. Throughout the workshop, participants recorded their individual and collective ideas in a common online workspace to which all had access. A preliminary synthesis of this information indicates that the concept of sustainability is a strong organizing principle for modern, liberal education requiring systems thinking, synthesis and contributions from all disciplines. Sustainability is inherently interdisciplinary and provides a framework for educational collaboration between and among geoscientists, natural/physical scientists, social scientists, humanists, engineers, etc.. This interdisciplinary framework is intellectually exciting and productive for educating students at all levels of higher education

    Full Text Available Background: Emotional intelligence (EI helps humans to perceive their own and others′ emotions. It helps to make better interpersonal communication that consequently leads to an increase in everyday performance and professional career. Teaching, particularly teaching in the clinical environment, is among the professions that need a high level of EI due to its relevance to human interactions. Materials and Methods: We adopted EI competencies with characteristics of a good clinical teacher. As a result, we extracted 12 strategies and then reviewed the literatures relevant to these strategies. Results: In the present article, 12 strategies that a clinical teacher should follow to use EI in her/his teaching were described. Conclusion: To apply EI in clinical settings, a teacher should consider all the factors that can bring about a more positive emotional environment and social interactions. These factors will increase students′ learning, improve patients′ care, and maintain her/his well-being. In addition, he/she will be able to evaluate her/his teaching to improve its effectiveness.

  6. Materialism.

    2012-05-01

    Materialism is nearly universally assumed by cognitive scientists. Intuitively, materialism says that a person's mental states are nothing over and above his or her material states, while dualism denies this. Philosophers have introduced concepts (e.g., realization and supervenience) to assist in formulating the theses of materialism and dualism with more precision, and distinguished among importantly different versions of each view (e.g., eliminative materialism, substance dualism, and emergentism). They have also clarified the logic of arguments that use empirical findings to support materialism. Finally, they have devised various objections to materialism, objections that therefore serve also as arguments for dualism. These objections typically center around two features of mental states that materialism has had trouble in accommodating. The first feature is intentionality, the property of representing, or being about, objects, properties, and states of affairs external to the mental states. The second feature is phenomenal consciousness, the property possessed by many mental states of there being something it is like for the subject of the mental state to be in that mental state.

    Using powerful computational resources and state-of-the-art methods of computational chemistry we contribute to the research on novel nuclear waste forms by providing atomic scale description of processes that govern the structural incorporation and the interactions of radionuclides in host materials. Here we present various results of combined computational and experimental studies on La{sub 1−x}Eu{sub x}PO{sub 4} monazite-type solid solution. We discuss the performance of DFT + U method with the Hubbard U parameter value derived ab initio, and the derivation of various structural, thermodynamic and radiation-damage related properties. We show a correlation between the cation displacement probabilities and the solubility data, indicating that the binding of cations is the driving factor behind both processes. The combined atomistic modeling and experimental studies result in a superior characterization of the investigated material.

  14. Study of the mechanisms of heavy-ion induced desorption on accelerator-relevant materials; Untersuchung der Mechanismen schwerioneninduzierter Desorption an beschleunigerrelevanten Materialien

    Energy Technology Data Exchange (ETDEWEB)

    Bender, Markus

    The ion beam loss induced desorption is a performance limitation for low charge state heavy ion accelerators. If charge exchanged projectile ions get lost onto the beam pipe, desorption of gas is stimulated resulting in a pressure increase inside of the synchrotron and thus, a dramatically reduction of the beam life time. To minimize the amount of desorbed gas an experimental program has been started to measure the desorption yields (released gas molecules per incident ion) of various materials and different projectile ions. The present work is a contribution to the understanding of the physical processes behind the ion beam loss induced desorption. The yield measurements by the pressure rise method have been combined for the rst time with in situ ion beam analysis technologies such as ERDA and RBS. With this unique method the desorption behavior of a sample can be correlated to its surface and bulk properties. The performed experiments with 1,4 MeV/u Xenon-Ions show that the ion induced desorption is mainly a surface effect. Sputtered oxide layers or impurities do not contribute to the desorbed gas significantly. Nevertheless bulk properties play an important role in the desorption strength. Pure metallic samples desorb less gas than isolating materials under swift heavy ion irradiation. From the experimental results it was possible to estimate the desorption yields of various materials under ion bombardment by means of an extended inelastic thermal-spike-model. The extension is the combination of the thermal-spike's temperature map with thermal desorption. Within this model the ion induced desorption can be regarded as the release of adsorbates from a transient overheated spot on the samples surface around the ion impact. Finally a copper substrate with a gold coated surface was developed and proposed as a suitable material for a beam loss collimator with minimum desorption to ensure the performance of GSI's SIS18 in high current beam operation.

    In this study, the effectiveness of the use of Question-Driven Levels of Inquiry Based Instruction (QD-LOIBI) assisted visual multimedia supported teaching materials on enhancing senior high school students scientific explanation ability has been studied. QD-LOIBI was designed by following five-levels of inquiry proposed by Wenning. Visual multimedia used in teaching materials included image (photo), virtual simulation and video phenomena. QD-LOIBI assisted teaching materials supported by visual multimedia were tried out on senior high school students at one high school in one district in West Java. A quasi-experiment method with design one experiment group (n = 31) and one control group (n = 32) were used. Experimental group were given QD-LOIBI assisted teaching material supported by visual multimedia, whereas the control group were given QD-LOIBI assisted teaching materials not supported visual multimedia. Data on the ability of scientific explanation in both groups were collected by scientific explanation ability test in essay form concerning kinetic gas theory concept. The results showed that the number of students in the experimental class that has increased the category and quality of scientific explanation is greater than in the control class. These results indicate that the use of multimedia supported instructional materials developed for implementation of QD-LOIBI can improve students’ ability to provide explanations supported by scientific evidence gained from practicum activities and applicable concepts, laws, principles or theories.

    Compositionally homogeneous mixed-material layers of Be and W, ∼2 μm thick, and of various W contents (spanning 0–100 at.% W), are produced by thermionic vacuum arc deposition. The layers are exposed to low energy (∼50 eV), high ion flux (6–8 × 10{sup 22} m{sup −2} s{sup −1}) D{sub 2}-0.1He (10% He) mixed species plasma at 473 K and 1073 K to simulate ITER-like first wall and divertor plasma-material interaction. Surface morphological and compositional analysis is conducted prior and subsequent to plasma exposure. The action of the plasma produces almost complete depletion of Be from the near surface, and this is found regardless of the exposure temperature or initial composition. In the exposure case of 473 K, thermal desorption spectrometry reveals decreased D retention in W rich compositions compared to similar exposure in D{sub 2} plasma without He, but no discernable difference is noted in Be rich compositions. At 1073 K, surface enrichment in W, by depletion of the Be, results in He induced W “fuzz” structures for all Be-W compositions explored.

    Relation between the thermodynamic parameters obtained from water sorption isotherms and the degree of reduction in the glass transition temperature (T g ), accompanied by water sorption, was quantitatively studied. Two well-known glassy food materials namely, wheat gluten and maltodextrin were used as samples. The difference between the chemical potential of water in a solution and that of pure water ([Formula: see text]), the difference between the chemical potential of solid in a solution and that of a pure solid ([Formula: see text]), and the change in the integral Gibbs free energy ([Formula: see text]) were obtained by analyzing the water sorption isotherms using solution thermodynamics. The parameter [Formula: see text] correlated well with ΔT g (≡T g  - T g0 ; where T g0 is the glass transition temperature of dry material), which had been taken to be an index of plasticizing effect. This indicates that plasticizing effect of water on foods can be evaluated through the parameter [Formula: see text].

  2. Effects of Crystallinity, Composition, and Texture on Hydrogen Solubility and Adsorption in Lunar Surface Materials and their Relevance to Remote Sensing

    Abundant spacecraft data now demonstrate the presence of features associated with H on the lunar surface. The origin of that lunar H, whether as OH or H2O, is some combination of endogenic (juvenile) sources in the interiors of planetary materials and those resulting from exogenic deposition such as from the solar wind or comets. The ability of mineral (rock) and glass surfaces to internally host and surficially adsorb H is a function of several interrelated variables -- composition, crystallinity, and texture -- all of which will have an effect on observed band depth in remote sensing measurements. Studies of terrestrial materials show that the ability of nominally-anhydrous minerals to host H is related to composition in ways that reflect partition coefficients for H between melt and mineral, variations in bond strengths, and defect densities. This is important because the ability of a mineral to adsorb water on its exterior surface (chemisorption) should be related to some of the same factors that govern 'solubility' of H in the interiors of different mineral groups and compositions. IR signatures of internal OH/H2O can easily be confused with those of adsorbed OH/H2O. No correlation between H solubility and surface adsorptivity is observed in pristine glasses, which generally have passivated bonds on the surface and are hydrophobic. However, on the Moon, glass 'matures' rapidly via micrometeorite bombardment, potentially exposing dangling bonds on the surface that provide sites for H to adsorb. Unlike glasses, crystalline materials provide both defect lattice sites and dangling bonds on freshly-fractured surfaces that may enhance H adsorption. For example, bonding on mineral surfaces ranges from hydrogen bonding at non-lattice oxygen atoms (electronegative sites) to chemisorption at electropositive surface sites, such as structural defects or unsatisfied cations. Moreover, glasses and different mineral species also have different optical absorption coefficients

    D implantation into Be-containing mixed material layers: Be, Be–W (W: ∼6 at.%) and Be–C (C: ∼50 at.%), was performed at elevated temperatures. The temperature dependence of D retention varied depending on the admixed element. D retention in Be and Be–W layers decreases with increasing implantation temperature, while the Be–C layers maintained rather high D retention in the present investigated temperature range (up to 623 K). D desorption behaviour from Be–C suggests the contribution of C–D bonds to D retention. W admixture into Be can significantly suppress D retention in Be. Long-term isothermal annealing at 513 and 623 K for D removal was also performed to simulate the ITER-wall-baking scenario. Even extended annealing at temperatures comparable to or lower than the implantation temperature does not lead to a significant release of retained D.

The preliminary study aims at finding out the phonological fossilization of adult learners of English in Javanese context and figuring out the factors influencing them. 25 fourth-semester Javanese students of English Departement from 5 universities in Semarang municipality were selected as respondents. The data were collected from observation, interview and documentation. The results show that phonological fossilizations occur on vowel (/e/ instead of /i/ in ‗english‘ /ˈɪŋ.glɪʃ/, /a/ instead of /æ/ in ‗aspect‘ /ˈæs.pekt/, it also occurs in /Ʌ,e, ǝ/ mostly in initial sound , consonant (/nð/ instead of /ð/ in ‗the‘ /ðǝ/, /ŋ/ instead of /ʤ/ in ‗change‘ /tʃeɪndʒ/, also in /tʃ, ϴ,ð,ʃ,v,Ʒ,z,j,k,g, suffix –ed and –es, and silent letter, and diphthong (/o/ instead of /ǝu/ in ‗over‘ /ǝuvǝr/ and in ‗power‘ /paʊər /, also in/ei,au/ . Factors affecting the occurrence of phonological fossilization are 1 the interference of respondents‘ mother tongue, such as Javanese tends to add sound /n/ in /nðǝlɔk/ ‗ndelok‘ and it interferes in pronouncing ‗the‘ to /nðǝ/ instead of /ðǝ/; 2 the learning materials of English Phonology course does not yet accommodate the learner‘s errors and or learner‘s fossilizations. These findings can be used as recommendation to develop teaching materials of English Phonology for EF2L.

Also, teaching methods such as visualization, simulation and experiment should be applied during the lessons. The use of this material will help students comprehend how subsurface currents in the straits, seas and oceans occur. By this simple experiment, students will be able to see what kind of a movement takes place under the Bosporus on which they travel by ferry and they will have the opportunity to carry it out themselves, making the lesson more fun.

    Full Text Available The article on the basis of archival documents examines the role of teaching staff of educational institutions of the Black Sea province during the First Russian revolution. The attention is paid to the participation of students of senior classes in the revolutionary movement. Among the materials are the archival documents of central and regional archives, namely the state archive of the Russian Federation, Russian state military historical archive, the state archive of the Krasnodar Krai, the center for documentation of contemporary history of Krasnodar Krai and the archive department of historical museum of city-resort Sochi. The authors come to the conclusion that on the territory of the Black Sea province, the activities of significant part of the teaching staff were aimed at destabilization of the political situation, contributing to the overthrow of the existing government. Rather than to protect the high schools students from the influence of political propaganda and to return students to the classrooms, some teachers have contributed to reverse the process, encouraging the study of the political programs of the parties and the desire to participate in the revolutionary movement. As a result, the schoolchildren, minors with unsettled teenage psychology participated in various revolutionary actions, which could lead to the tragic consequences.

  16. Informatics in radiology: RADTF: a semantic search-enabled, natural language processor-generated radiology teaching file.

    2010-11-01

    Storing and retrieving radiology cases is an important activity for education and clinical research, but this process can be time-consuming. In the process of structuring reports and images into organized teaching files, incidental pathologic conditions not pertinent to the primary teaching point can be omitted, as when a user saves images of an aortic dissection case but disregards the incidental osteoid osteoma. An alternate strategy for identifying teaching cases is text search of reports in radiology information systems (RIS), but retrieved reports are unstructured, teaching-related content is not highlighted, and patient identifying information is not removed. Furthermore, searching unstructured reports requires sophisticated retrieval methods to achieve useful results. An open-source, RadLex(®)-compatible teaching file solution called RADTF, which uses natural language processing (NLP) methods to process radiology reports, was developed to create a searchable teaching resource from the RIS and the picture archiving and communication system (PACS). The NLP system extracts and de-identifies teaching-relevant statements from full reports to generate a stand-alone database, thus converting existing RIS archives into an on-demand source of teaching material. Using RADTF, the authors generated a semantic search-enabled, Web-based radiology archive containing over 700,000 cases with millions of images. RADTF combines a compact representation of the teaching-relevant content in radiology reports and a versatile search engine with the scale of the entire RIS-PACS collection of case material. ©RSNA, 2010

  17. Faculty Viewpoints on Teaching Quantway®

    Heather Howington

    2015-01-01

    Full Text Available Quantway is a quantitative reasoning-based pathway for developmental math that has been developed as an alternative to the traditional remedial algebra sequence. To explore the experiences of faculty involved with Quantway, we interviewed eight individuals who have taught the course in the past year to survey their attitudes and opinions about students in their classes, the materials and pedagogies in use, and the collegial interaction of networked faculty. Faculty were selected with the intention of gathering a broad set of opinions resulting from differences of location, experience, and other factors. In this paper, we summarize those interviews by identifying common themes reported by the faculty that highlight strengths and challenges of teaching Quantway. Themes include perceptions about changes in student engagement and attitudes as well as changes in their own mindset; the evolution of teaching strategies and materials used inside and outside the classroom; and the relevance of connections between faculty at different institutions involved in the project.

    2017-01-01

    Full Text Available The study of history is becoming increasingly less interesting to students, despite the fact that the history teaching process has been continuously modernized during recent years. It is an observation which can be perceived even if we don`t make an elaborated research in the field. Some empirical data show us that students in secondary and High Schools are less interested in studying History than in studying Geography or other social sciences. The number of students who are determined to study History in universities has significantly dropped in recent years [1]. Of course, there are multiple causes and the factors behind this change are numerous and varied. In this paper we handle only some changes in teaching History in High Schools, as they are designed in History Curricula and in History textbooks. Therefore during the first sequence of this paper we shall analyze the History Curricula for High School, 11th and 12th grades, regarding their finalities (competencies, some relevant contents and the recommended pedagogical approaches about the teaching methods and the auxiliary material. In the second part of the paper we propose some teaching activities through which students would practice the specific competencies from their Curriculum for History. We aim at presenting attractive teaching material and learning methods and applying the methodological recommendations from the High school Curricula for History, 11th and 12th grades.

    Traditionally in the center of the interest on quantum physics referring to schools the question lies, whether electrons or photons are now particles or waves, a question, which is often characterized by the phrase ''wave-particle dualism'', which notoriously not exists in its original meaning. Against that by the author - on the base of important preparatory works of Kueblbeck and Mueller - a new concept of quantum physics for the school was proposed, which puts ''basic facts'' in the foreground, comparable with the Kueblbeck-Mueller ''characteristic features''. The ''basic facts'' are similar to axioms of quantum physics, by means of them a large number of experiments and phenomena can be ''explained'' at least qualitatively - in a heuristic way -. Instead of the so-called ''wave-particle dualism'' uncertainty and complementarity are put in the foreground. The new concept is in the Internet under http://www.forphys.de extensively presented with many further materials. In the partial volumes of this publication manifold and carefully elaborated teaching materials are presented, by which scholars can get themselves the partial set of quantum physics referring to schools by different methods like learning at stations, short referates, Internet-research, group puzzle, the query-sheet or the card-index method etc. In the present 3. part materials are prepared, by which scholars can get foundations of atomic physics and interpret in the sense of the ''basic facts or quantum physics''. Here deals it thus with discrete energy levels, the linear potential box, with atomic models, the atomic structure, the tunnel effect, and - because curricula it often require - also with the Schroedinger equation. The materials can also be usefully applied in other concepts.

    A solar decontamination process for water was developed using photocatalysts supported on sea bottom sediments with sodium silicate. The supported catalysts were systematically optimized with respect to TiO/sub 2/ dosages, calcinations temperature and binder dosages. The Young's Modulus value (compressed strength) was found 12.5 kN/mm/sub 2/ of optimized supported catalyst which would not mixed with the water of real samples during the photocatalysis. The composition of the optimized catalyst was selected as sediments 82%, TiO /sub 2/ 15% and Na/sub 2/SiO/sub 3/ 3%, where the sintering temperature was 750degreeC. Humic acid as a model compound was used to evaluate the degradation efficiency of the developed sintering material. The complete mineralization of humic acid was achieved by 40 h sunlight irradiation. About 100 ml of (15 mg/L) of humic acid was successfully degraded with 15 g sintering materials under sunlight irradiation. The solar photocatalytical degradation treatment is simple, easy handling and cheap. Therefore, since the artificial lamp devices, for example Hg-Xe lamp, are particularly expensive in the local and nonexclusive areas, the optimized developed sintering material appears to be very suitable treatment method for humic acid in those area

    2011-09-01

    Based on Chinese published literature and personal observations, this article reviews the history of bilingual teaching in nursing education in China, describes its current status and challenges, and predicts its future directions. Bilingual teaching in nursing education enjoys increasing popularity in China. The major factors that affect bilingual teaching are bilingual educators, students' English-language levels, bilingual teaching materials, and teaching models. Based on surveys of nursing schools, the English-language proficiency of the nursing educators varies greatly. The main issues with the teaching methods lie in over-translation, cramming, and limited interaction between the students and the teachers. Despite relatively inadequate English-language proficiency among Chinese nursing students, their interest can be strengthened greatly if international exchanges are available and promoted. Bilingual textbooks are more suitable in China's national context because of pricing and relevance. Although immersive bilingual teaching is the ideal, it is more feasible to begin with infiltrative bilingual teaching and move progressively towards increased English-language penetration. Future directions for improving bilingual teaching include training teaching faculty members, strengthening international exchanges, providing better bilingual study atmospheres, and gradually implementing bilingual textbooks. © 2011 Blackwell Publishing Asia Pty Ltd.

  16. Languaging in and about Lunyole: African Storybook materials as a catalyst for re-imagining literacy teaching and learning in two Ugandan primary schools

    Directory of Open Access Journals (Sweden)

    2016-07-01

    Full Text Available Throughout sub-Saharan Africa, many children are not learning to read competently in the first 3 years of primary school; thus, both ‘reading to learn’ and ‘reading for pleasure’ in these early years, and in higher grades, are constrained. Two of the many reasons for reading failure are the absence of suitable materials in languages with which learners are familiar and teachers’ limited knowledge of pedagogic practices that support reading development. In this article, we describe the African Storybook (ASb initiative as one imaginative response to the dearth of interesting and accessible stories in local languages and report findings from the first phase of a professional development project in which teacher-researchers in two Ugandan schools are using ASb materials to ‘language’ in Lunyole at the meetings of their action research group. We argue that their investment in extending their literacy in a language which they speak more fluently than they read or write, and the contestations over written forms of this language that have surfaced in some of the discussions, are likely to be productive for their professional development as teachers and for their participation in ongoing community debates about the orthography of a recently codified and standardised language. By languaging together in Lunyole, with ASb materials as the main object of their conversations and activities, the teacher-researchers have begun to develop capabilities that are likely to benefit the Lunyole/ English biliteracy of the learners whom they teach. They are imagining new possibilities for themselves and for the learners.

    2012-01-01

    Audiovisual learning resources have become valuable adjuncts to formal teaching in surgical training. This report discusses the process and challenges of preparing an audiovisual teaching tool for laparoscopic cholecystectomy. The relative value in surgical education and training, for both the creator and viewer are addressed. This audiovisual teaching resource was prepared as part of the Master of Surgery program at the University of Sydney, Australia. The different methods of video production used to create operative teaching tools are discussed. Collating and editing material for an audiovisual teaching resource can be a time-consuming and technically challenging process. However, quality learning resources can now be produced even with limited prior video editing experience. With minimal cost and suitable guidance to ensure clinically relevant content, most surgeons should be able to produce short, high-quality education videos of both open and minimally invasive surgery. Despite the challenges faced during production of audiovisual teaching tools, these resources are now relatively easy to produce using readily available software. These resources are particularly attractive to surgical trainees when real time operative footage is used. They serve as valuable adjuncts to formal teaching, particularly in the setting of minimally invasive surgery. Copyright © 2012 Association of Program Directors in Surgery. Published by Elsevier Inc.

  1. Advancing Climate Literacy through Investment in Science Education Faculty, and Future and Current Science Teachers: Providing Professional Learning, Instructional Materials, and a Model for Locally-Relevant and Culturally-Responsive Content

    Science.gov (United States)

    Halversen, C.; Apple, J. K.; McDonnell, J. D.; Weiss, E.

    2014-12-01

    The Next Generation Science Standards (NGSS) call for 5th grade students to "obtain and combine information about ways individual communities use science ideas to protect Earth's resources and environment". Achieving this, and other objectives in NGSS, will require changes in the educational system for both students and teachers. Teachers need access to high quality instructional materials and continuous professional learning opportunities starting in pre-service education. Students need highly engaging and authentic learning experiences focused on content that is strategically interwoven with science practices. Pre-service and early career teachers, even at the secondary level, often have relatively weak understandings of the complex Earth systems science required for understanding climate change and hold alternative ideas and naïve beliefs about the nature of science. These naïve understandings cause difficulties in portraying and teaching science, especially considering what is being called for in NGSS. The ACLIPSE program focuses on middle school pre-service science teachers and education faculty because: (1) the concepts that underlie climate change align well with the disciplinary core ideas and practices in NGSS for middle grades; and (2) middle school is a critical time for capturing students interest in science as student engagement by eighth grade is the most effective predictor of student pursuit of science in high school and college. Capturing student attention at this age is critical for recruitment to STEM careers and lifelong climate literacy. THE ACLIPSE program uses cutting edge research and technology in ocean observing systems to provide educators with new tools to engage students that will lead to deeper understanding of the interactions between the ocean and climate systems. Establishing authentic, meaningful connections between indigenous and place-based, and technological climate observations will help generate a more holistic perspective

    Adaptation is a key strategy to deal with the effects of climate change, and it can also be a key strategy in teaching climate literacy. Adapting curriculum to include utilizing new instructional practices, modifying existing lessons, evaluating evidence and engaging students in real-world projects are strategies employed in Recharge the Rain. Arizona Project WET and Watershed Management Group developed the Recharge the Rain project, through a NOAA Environmental Literacy Grant, to build community resiliency to hazards associated with increased temperatures, drought and flooding in Arizona. Sixth through twelfth grade teachers, students and the public will move through a continuum from awareness, to knowledge gain, to conceptual understanding, to action. During the first year of the project, through professional development and ongoing guidance, teachers developed a climate literacy curriculum to use in their classrooms. Using systems thinking language and structure from the Cabrera Research Labs, teachers and students gain the thinking tools necessary to increase understanding of Earth's climate system. Lessons and resources for teaching about climate change are abundant and many, such as those on the Climate Literacy Education Awareness Network (CLEAN), have gone through an extensive review process. By cataloguing online resources and sharing these with teachers through a social bookmarking tool, wakelet.com, teachers are easily able to find appropriate teaching material. Engaging students in evaluating evidence requires the data to be relevant to their everyday lives. Online data resources are readily available from NOAA and other sources at both the global and local levels. When teachers, students and the public contribute to the data collection process in citizen science projects such as CoCoRaHS, iSeeChange, and USA National Phenology Network, the data empowers them to act in ways to mitigate the climate threats in their community.

    Full Text Available Nowadays, learning a foreign language becomes necessary; the importance of teaching Turkish to the foreigners is getting more and more. Although Turkish is a rooted language, it is quite a new field to teach Turkish as a foreign language. Varies studies have been applied on teaching Turkish as s foreign language and came a long way. However, when it is examined, it can be seen that one of the most common problems of teaching Turkish to the foreigners is the lack of teaching materials. Animation as a material used in teaching Turkish to the foreigners has become remarkable day by day. In foreign language teaching, visuality is an important factor on permanent learning, thus animation plays an important role in teaching foreign languages. In this study aiming at using animation as an alternative to the lack of materials and to provide permanent learning, activities are developed according to the Common European Framework of Reference. Activities are designed by using the animation “Bee Movie” produced in 2007. The activities are prepared to develop main language skills (listening, writing, speaking and reading on A1 level. In each activity, duration, target language skill, educational attainment, materials and application of the activities have been explained. In this study it is expressed that these activities will be a solution for material scarcity by enriching the learning atmosphere, increasing student motivation, providing individual education, providing the improvement of students’ language skills, converting abstract topics into concrete and providing permanent learning.

    Cultural diversity challenges health care providers to facilitate bridging cross-cultural gaps with clients. It is through providing culturally relevant care that health care practitioners truly serve the needs of all clients in our diverse society. A theory of Cultural Care Diversity and Universality offers a framework for building linkages of clinical knowledge to cultural care. A four-step approach to providing culturally sensitive patient teaching is described: (1) health care providers should assess their own cultural beliefs and be aware of general ethnic, regional, and religious beliefs and practices in their area; (2) develop a teaching plan; (3) implement the plan; (4) evaluate the success of the teaching-learning process and make alterations based on evaluation. When providers assess clients' beliefs and practices and incorporate them into the teaching plan design, teaching becomes more relevant and clients become more successful at learning.

    The AGU Position Statement, "Human-Induced Climate Change Requires Urgent Action," calls on scientists to "[work] with stakeholders to identify relevant information, and [to convey] understanding clearly and accurately, both to decision makers and to the general public". Everyday, K-12 teachers communicate with an important segment of the general public, and they represent important stakeholders with unique needs. The terms 'global warming', 'greenhouse effect', and 'climate change' appear nowhere in the 1996 National Science Education Standards, but under the Next Generation Science Standards, millions of teachers- most of whom have little to no experience teaching about climate change- will be required to cover the topic. This presentation discusses research conducted with five veteran public school teachers, each of whom has been teaching about climate change for many years. The group comprises three high school teachers, a middle school teacher, and an elementary school teacher. The study examined: 1) What these teachers teach about climate change; 2) How they teach about climate change; 3) What resources they use in teaching and learning about climate change; and 4) How they think the scientific community can support teachers in their efforts to teach about climate change. The teachers varied in their teaching practices and in their conceptions of 'climate change', but they all said that the academic community can support climate change education by developing locally relevant educational resources. Scientists working with K-12 teachers can build on the work of these master teachers, and attendees can access detailed descriptions of all of the lessons and the associated learning materials.

    In the frame of the reported project, together with the programme partners, optimization of service relevant properties as well as modification of manufacturing procedures for the forged alloy Nimonic 101 were achieved. These results are directly implementable into serial production and cause improved service reliability and economic benefit. For the forged alloy Udimet 720 materials data were generated in accordance with the programme plan. The final evaluation for this alloy will be performed by the project partner Siemens-KWU. The qualification of fine-grained investment cast blades of IN 792 for large rear=stage blading is not yet fully completed. Three major questions are lacking final answers: - Does a stress rupture strength advantage exist over the forged alloy Udimet 720/coarse/grained? - Can a high cycle fatigue strength as high as that for Udimet 720/coarse-grained be met reproducibly? - Does the investment cast blades offer a cost advantage over the forged ones - technical qualification assumed? The programme helped significantly in preparing the right answers to these questions. (orig.) [Deutsch] Im Rahmen des berichteten Teilvorhabens ist es in Zusammenarbeit mit den Projektpartnern gelungen, fuer die Schmiedelegierung Nimonic 101 die betriebsrelevanten Eigenschaften zu optimieren, sowie die Schaufelherstellung so zu modifizieren, dass die Betriebszuverlaessigkeit verbessert wird.

  14. Towards a generic procedure for the detection of relevant contaminants from waste electric and electronic equipment (WEEE) in plastic food-contact materials: a review and selection of key parameters.

    Recently, traces of brominated flame retardants (BFRs) have been detected in black plastic food-contact materials (FCMs), indicating the presence of recycled plastics, mainly coming from waste electric and electronic equipment (WEEE) as BFRs are one of the main additives in electric applications. In order to evaluate efficiently and preliminary in situ the presence of WEEE in plastic FCMs, a generic procedure for the evaluation of WEEE presence in plastic FCMs by using defined parameters having each an associated importance level has been proposed. This can be achieved by combining parameters like overall bromine (Br) and antimony (Sb) content; additive and reactive BFR, rare earth element (REE) and WEEE-relevant elemental content and additionally polymer purity. In most of the cases, the WEEE contamination could be confirmed by combining X-ray fluorescence (XRF) spectrometry and thermal desorption/pyrolysis gas chromatography-mass spectrometry (GC-MS) at first. The Sb and REE content did not give a full confirmation as to the source of contamination, however for Sb the opposite counts: Sb was joined with elevated Br signals. Therefore, Br at first followed by Sb were used as WEEE precursors as both elements are used as synergetic flame-retardant systems. WEEE-specific REEs could be used for small WEEE (sWEEE) confirmation; however, this parameter should be interpreted with care. The polymer purity by Fourier-transform infrared spectrometer (FTIR) and pyrolysis GC-MS in many cases could not confirm WEEE-specific contamination; however, it can be used for purity measurements and for the suspicion of the usage of recycled fractions (WEEE and non-WEEE) as a third-line confirmation. To the best of our knowledge, the addition of WEEE waste to plastic FCMs is illegal; however, due to lack on screening mechanisms, there is still the breakthrough of such articles onto the market, and, therefore, our generic procedure enables the quick and effective screening of suspicious

The message can be knowledge, skills, ideas, experiences, and many others. Through the process of communication, the people can receive the message or information. To avoid misunderstanding in the process of communication, media are needed in the process of teaching. Magazine can be other alternative as reading material in the classroom. Magazine as reading material has appeal for the students. To make the students get information from magazine, the teacher can ask the students to observe table of content and giving the students training to use it. Like, what is done on text book.

    NASA Goddard Space Flight Center has developed a systemic educator professional development model for the integration of NASA climate change resources into the K-12 classroom. The desired outcome of this model is to prepare teachers in STEM disciplines to be globally engaged and knowledgeable of current climate change research and its potential for content relevancy alignment to standard-based curriculum. The application and mapping of the model is based on the state education needs assessment, alignment to the Next Generation Science Standards (NGSS), and implementation framework developed by the consortium of district superintendents and their science supervisors. In this presentation, we will demonstrate best practices for extending the concept of inquiry-based and project-based learning through the integration of current NASA climate change research into curriculum unit lessons. This model includes a significant teacher development component focused on capacity development for teacher instruction and pedagogy aimed at aligning NASA climate change research to related NGSS student performance expectations and subsequent Crosscutting Concepts, Science and Engineering Practices, and Disciplinary Core Ideas, a need that was presented by the district steering committee as critical for ensuring sustainability and high-impact in the classroom. This model offers a collaborative and inclusive learning community that connects classroom teachers to NASA climate change researchers via an ongoing consultant/mentoring approach. As a result of the first year of implementation of this model, Maryland teachers are implementing NGSS unit lessons that guide students in open-ended research based on current NASA climate change research.

    Full Text Available As research and funding continue to replace teaching as the central mission in more colleges and universities, nursing faculty will be expected to engage in research endeavours as proof of scholarship involvement. However, the multiple roles of the nursing faculty coupled with the pressure to engage in research and funding endeavours have led to increased stress and burnout and increased attrition rate. The purpose of this paper is to delineate the expected roles of the nursing faculty related to the trilogy of teaching, research and service and recommend that colleges/universities recognize not only research as scholarship, but also teaching and service. An integrative review of the literature using books and journals from nursing and other relevant disciplines related to the multiple roles of nursing faculty was conducted. Teaching is a vital role and should remain the central mission of colleges/universities to ensure effective pedagogy. Institutions of higher learning should adapt an umbrella of scholarship under which falls teaching, research, and service; thus, teaching would be considered scholarship.

  5. The Limits to Relevance

    Science.gov (United States)

    Averill, M.; Briggle, A.

    2006-12-01

    Science policy and knowledge production lately have taken a pragmatic turn. Funding agencies increasingly are requiring scientists to explain the relevance of their work to society. This stems in part from mounting critiques of the "linear model" of knowledge production in which scientists operating according to their own interests or disciplinary standards are presumed to automatically produce knowledge that is of relevance outside of their narrow communities. Many contend that funded scientific research should be linked more directly to societal goals, which implies a shift in the kind of research that will be funded. While both authors support the concept of useful science, we question the exact meaning of "relevance" and the wisdom of allowing it to control research agendas. We hope to contribute to the conversation by thinking more critically about the meaning and limits of the term "relevance" and the trade-offs implicit in a narrow utilitarian approach. The paper will consider which interests tend to be privileged by an emphasis on relevance and address issues such as whose goals ought to be pursued and why, and who gets to decide. We will consider how relevance, narrowly construed, may actually limit the ultimate utility of scientific research. The paper also will reflect on the worthiness of research goals themselves and their relationship to a broader view of what it means to be human and to live in society. Just as there is more to being human than the pragmatic demands of daily life, there is more at issue with knowledge production than finding the most efficient ways to satisfy consumer preferences or fix near-term policy problems. We will conclude by calling for a balanced approach to funding research that addresses society's most pressing needs but also supports innovative research with less immediately apparent application.

    Subspace clustering aims at detecting clusters in any subspace projection of a high dimensional space. As the number of possible subspace projections is exponential in the number of dimensions, the result is often tremendously large. Recent approaches fail to reduce results to relevant subspace...... clusters. Their results are typically highly redundant, i.e. many clusters are detected multiple times in several projections. In this work, we propose a novel model for relevant subspace clustering (RESCU). We present a global optimization which detects the most interesting non-redundant subspace clusters...... achieves top clustering quality while competing approaches show greatly varying performance....

    2012-10-01

    Full Text Available The incidence of obesity has increased dramatically during recent decades. Obesity increases the risk for metabolic and cardiovascular diseases and may therefore contribute to premature death. With increasing fat mass, secretion of adipose tissue derived bioactive molecules (adipokines changes towards a pro-inflammatory, diabetogenic and atherogenic pattern. Adipokines are involved in the regulation of appetite and satiety, energy expenditure, activity, endothelial function, hemostasis, blood pressure, insulin sensitivity, energy metabolism in insulin sensitive tissues, adipogenesis, fat distribution and insulin secretion in pancreatic β-cells. Therefore, adipokines are clinically relevant as biomarkers for fat distribution, adipose tissue function, liver fat content, insulin sensitivity, chronic inflammation and have the potential for future pharmacological treatment strategies for obesity and its related diseases. This review focuses on the clinical relevance of selected adipokines as markers or predictors of obesity related diseases and as potential therapeutic tools or targets in metabolic and cardiovascular diseases.

  20. Radiology seminars using teaching kits

    1989-01-01

    Clinco-radiological seminars are an effective method of teaching medical students. However, in busy departments it is often difficult to provide enough radiologists for small group instruction. This can be facilitated by the use of prepared teaching kits. Each kit contains a set of duplicated films and a syllabus which gives a short clinical history for each patient and a series of questions to be used to direct the discussion. Each diagnostic problem is chosen to demonstrate core material. We have been using these teaching kits for organ system teaching in the preclerkship year. Teaching kits offer several advantages. They make it easier to recruit seminar leaders through efficient use of their time. The use of duplicated films and a syllabus ensures that all students cover the same material. The syllabus can be used to generate examination questions for reinforcement of important concepts. The kits are also available to students to review alone and can be readily updated as required

    Military academies have two distinctive characteristics on talent training: Firstly, we must teach facing actual combat and connecting with academic frontier. Secondly, the bachelor's degree education and the military education should be balanced. The teaching mode of basic curriculum in military academies must be reformed and optimized on the basis of the traditional teaching mode, so as to ensure the high quality of teaching and provide enough guidance and help for students to support their academic burden. In this paper, our main work on "Applied Optics" teaching mode reform is introduced: First of all, we research extensively and learn fully from advanced teaching modes of the well-known universities at home and abroad, a whole design is made for the teaching mode of the core curriculum of optical engineering in our school "Applied Optics", building a new teaching mode which takes the methods of teaching basic parts as details, teaching application parts as emphases, teaching frontier parts as topics and teaching actual combat parts on site. Then combining with the questionnaire survey of students and opinions proposed by relevant experts in the teaching seminar, teaching effect and generalizability of the new teaching mode are analyzed and evaluated.

    Diarrhea remains the third leading cause of death in children under five years, despite recent advances in the management and prevention of this disease. It is caused by multiple pathogens, however, the prevalence of each varies by age group, geographical area and the scenario where cases (community vs hospital) are recorded. The most relevant pathogens in public health are those associated with the highest burden of disease, severity, complications and mortality. In our country, norovirus, Campylobacter and diarrheagenic E. coli are the most prevalent pathogens at the community level in children. In this paper we review the local epidemiology and potential areas of development in five selected pathogens: rotavirus, norovirus, Shiga toxin-producing E. coli (STEC), Shigella and Salmonella. Of these, rotavirus is the most important in the pediatric population and the main agent responsible for child mortality from diarrhea. The introduction of rotavirus vaccination in Peru will have a significant impact on disease burden and mortality from diarrhea. However, surveillance studies are needed to determine the impact of vaccination and changes in the epidemiology of diarrhea in Peru following the introduction of new vaccines, as well as antibiotic resistance surveillance of clinical relevant bacteria.

    Full Text Available Since 21 century, with the wide spread in family and public, network has been applied in many new fields, and the application in classes is of no exception. In traditional education, teachers give lessons to students face to face. Hence, the teaching quality depends largely on the quality and initiative of the individual teacher. However, the serious disadvantages of this mode are that teachers completely dominate the classroom and may ignore the subjective cognition role of the students, which may be bad for the growth of creativity and the innovative thinking ability. Obviously, traditional education mode cannot meet the requirements of the this new era which leads to the booming developing tendency of the network. As a new teaching measure, scientifically combining modern information technology and teaching practice, network teaching not only changes the traditional education by the means and form, but even also gives new meanings to teaching concept, process, method as well as teacher-student role and other deep levels. With the help of network teaching system, on-line classroom learning, relevant information systematization, standardization and automation, this system provides students with an efficient online learning method with high quality. This also helps to solve the disadvantages of the traditional teaching mode and promote the teaching methods to a new stage. It improves the network teaching platform, enriches the network teaching resources, and establishes a network teaching system, so as to improve information quality of teachers and students and assist in improving teaching quality of schools.

  4. Evolving Roles For Teaching Assistants In Introductory Courses

    2008-12-01

    As we bring new research-based learning approaches, curricular innovations, and student engagement practices into the introductory science classroom, expectations of teaching assistants (TAs) should have, and have, changed. Similarly, the 21st century teaching assistant has different expectations of us. Maintaining relevance in this context means bringing TAs into an integrated teaching team that supports effective learning for students and provides structured professional development opportunities for TAs. A number of support efforts on our campus, with counterparts at many other universities, seek to optimize the instructional impact of faculty and teaching assistants, thus opening the door to enhanced student engagement (e.g. the quality of effort students put forth, their persistence in science and/or engineering courses, and their perception of scientific relevance in everyday life). Among these efforts, School of Earth Sciences course development TAs work 1:1 in advance of the term with introductory course faculty to design exercises and course materials that meet clearly articulated student learning goals or pedagogical challenges. Throughout the process, TAs are mentored by the faculty as well as science pedagogy experts. Initially funded by a major teaching award, the School is now moving to institutionalize this successful program which has broadened the definition of the TA role. Another area of optimization, reflecting Shulman's concept of pedagogical content knowledge, is our campus mandate that TA development take place within a departmental, as well as general, context. Both Chemistry and Physics expect introductory course TAs to lead interactive, guided-inquiry or tutorial-style sections. Integrating these sections with lecture and positively reinforcing course goals requires TA buy-in and a set of pedagogical facilitation skills cultivated through course-specific training and active mentoring while teaching. To better support the mentoring process

    Energy Technology Data Exchange (ETDEWEB)

    Menrad, Andreas

    2013-09-01

    To obtain approval as dangerous goods packaging, different experimental tests are required to show the eligibility for the transportation of those goods. The data obtained from the material test performed on the pressed plates is not used to get absolute values for the failure time in an internal pressure test or the medium drop height. The goal is to see if there are changes in the behavior because a different HDPE is being used. All the jerrycans and pressed plates were specially made of four different materials to gain knowledge about the material properties. The plates and jerrycans were made of resin from the same batch to prevent variations caused by batch differences. The wall thickness is decisive and, therefore packagings were analyzed using computer tomography and the fringe projection technique. The results were compared to the magnetostatic measurement technique. The deformation under internal pressure was measured by digital image correlation. Deformations in the radial direction and the equivalent strains were determined. These deformations, strains, and their acceleration due to the swelling effect could be reproduced in the finite element analysis by using the temperature in the material model. The resistance against both internal pressure and absorption depend on the density of the material. Conditioning at elevated temperatures causes post crystallization and reduces internal stresses. Differences in the densities of the materials can be determined by using plates manufactured by compression molding. A higher density leads to a better performance under internal pressure. A correlation could be proved between the medium failure drop height (50 % of the packagings fail because of a crack) and the tensile impact strength of notched specimens cut out of the jerrycans side walls and the notched impact strength (NIS) of pressed plates. A higher NIS leads to a higher medium failure drop height. A low resistance against oxidative degradation will reduce

The rate of strategy adoption is determined by the payoff difference and a teaching activity characterizing the donor's capability to enforce its strategy on the opponent. Each successful strategy adoption process is accompanied by an increase in the donor's teaching activity. By applying an optimum value of the increment, this simple mechanism spontaneously creates relevant inhomogeneities in the teaching activities that support the maintenance of cooperation for both the prisoner's dilemma and the snowdrift game

    The basics for the understanding of radioactivity and radioprotection are set in the secondary school. Therefore the German-Swiss Radiation Protection Association already is trying to support the appropriate teaching of relevant topics in school for a long time. Unfortunately experiments with radioactive material are hampered in Germany by complex and confusing legislation. In this contribution the framework is described which is given by the German legislation for the use of radioactive sources in secondary schools. Additionally proposals for different simple experiments with radioactivity are presented which can be easily implemented in teaching and alternative methods are introduced like e.g. virtual experiments.

    2015-01-01

    We developed and offered a sequence of neuroscience courses geared toward changing the way non-science students interact with the sciences. Although we accepted students from all majors and at all class levels, our target population was first and second year students who were majoring in the fine arts or the humanities, or who had not yet declared a major. Our goal was to engage these students in science in general and neuroscience in particular by teaching science in a way that was accessible and relevant to their intellectual experiences. Our methodology was to teach scientific principles through the humanities by using course material that is at the intersection of the sciences and the humanities and by changing the classroom experience for both faculty and students. Examples of our course materials included the works of Oliver Sacks, V.S. Ramachandran, Martha Nussbaum, Virginia Woolf and Karl Popper, among others. To change the classroom experience we used a model of team-teaching, which required the simultaneous presence of two faculty members in the classroom for all classes. We changed the structure of the classroom experience from the traditional authority model to a model in which inquiry, debate, and intellectual responsibility were central. We wanted the students to have an appreciation of science not only as an endeavor guided by evidence and experimentation, but also a public discourse driven by creativity and controversy. The courses attracted a significant number of humanities and fine arts students, many of whom had already completed their basic science requirement.

    Promoting family planning (FP) is a key strategy for health, economic and population growth. Sub-Saharan Africa, with one of the lowest contraceptive prevalence and highest fertility rates globally, contributes half of the global maternal deaths. Improving the quality of FP services, including enhancing pre-service FP teaching, has the potential to improve contraceptive prevalence. In efforts to improve the quality of FP services in Tanzania, including provider skills, this study sought to identify gaps in pre-service FP teaching and suggest opportunities for strengthening the training. Data were collected from all medical schools and a representative sample of pre-service nursing, Assistant Medical Officer (AMO), Clinical Officer (CO) and assistant CO schools in mainland Tanzania. Teachers responsible for FP teaching at the schools were interviewed using a semi-structured questionnaire. Observations on availability of teaching resources and other evidence of FP teaching and evaluation were documented. Relevant approved teaching documents were assessed for their suitability as competency-based FP teaching tools against predefined criteria. Quantitative data were analyzed using EPI Info 6 and qualitative data were manually analyzed using content analysis. A total of 35 pre-service schools were evaluated for FP teaching including 30 technical education and five degree offering schools. Of the assessed 11 pre-service curricula, only one met the criteria for suitability of FP teaching. FP teaching was typically theoretical with only 22.9% of all the schools having systems in place to produce graduates who could skillfully provide FP methods. Across schools, the target skills were the same level of competence and skewed toward short acting methods of contraception. Only 23.3% (n = 7) of schools had skills laboratories, 76% (n = 22) were either physically connected or linked to FP clinics. None of the degree providing schools practiced FP at its own teaching hospital

    The declared aim of the present project was to develop reliable and powerful detection methods for platinum metals and in particular platinum. Special emphasis was placed on practicability and transferability to other applications. This meant that the sample preparation techniques and detection methods employed would have to be available to other laboratories without significant prior investment costs. On the hand the analysis method had to meet very exacting requirements because platinum metals are among the rarest substances contained in the Earth`s crust (1x10-7%-10x10-7%) and the element quantities and concentrations to be detected are in range of 10-12g or 10-9g/kg(L), respectively.

    1999-01-01

    Airbag pressure vessels for the north-American market mainly are made by forging and by the use of steel alloys. In Europe aluminum alloys are common and the manufacturing process is extrusion of circular blanks - made from cold rolled plates - in a form applying a 100 t press at room temperature. Then by heat treatment the strength/hardness of the material is properly adjusted and after that the pressure vessel parts have to be continuously inspected with an inspection and handling cycle time of 3 s. Inspection of the axis-symmetric parts is asked for surface breaking extrusion defects as well as for surface parallel delaminations in the bulk volume. Furthermore, the material strength is a quality characteristic that has to be nondestructively registered and documented. The inspection is performed by eddy current probes and an EMAT, of which the eddy current impedance measurements are used for surface breaking extrusion defect detection and sizing (single frequency technique with digital locus curve filtering) and strength characterization (3-frequency technique with digital filtering for signal-to-noise enhancement). The bulk delaminations are detected by an EMAT-resonance technique using a spiral eddy current coil and permanent magnets for the EMA-energy transformation. The inspections are performed by singling the parts on a conveying belt, rotating two of them parallel on turntables scanning with the transducers in specially selected circular scan paths. The performance of the system is characterized by a number of 6000 parts per shift in the two time-parallel inspection lines with 3 shifts in 24 hours. The registered quality characteristics are documented by laser writing onto the surface of each part. The emphasis of the contribution is on the presentation and discussion of the safety and economical benefits by process-integrated NDT. (author)

    Full Text Available Education is reforming with the birth of the internet. Learning is not solely based on classroom basis but also through on-line. The revolution of Internet has transformed teaching via face-to-face into virtual teaching. The expansion of teaching deliveries suggests that we need interactive mechanism to accommodate course material for on-line students. However, creating on-line materials requires the conception of on-line instructional design. A suitable online material design will allow learners to engage with learning. Learners will have opportunities to develop their own understanding. In addition, suitable learning material will strengthen learner’s knowledge construction from their short-term memory to long-term memory. The purpose of this paper is to discover the learning material design approach based on gender by evaluating lecturer’s adoption of online material design using Keller’s ARCS model. The sample consisting of 30 lecturers from distance education learning reveals that gender differs in their adoption of learning material design specifically on getting attention of the student. The result also shows that relevance and satisfaction contribute to gender differences in learning material adoption. Limitations of the study and practical implications of these findings discussed.

    Ortiz de Montellano, B.

    1996-11-14

    As planned a letter was sent out to 17 teachers who had participated in a Summer 1994 workshop on ``Culturally Relevant Science for Hispanics`` at Michigan State. These teachers were supposed to have spent the intervening time developing lesson plans and curricula. The letter requested a report of any activities undertaken and copies of lesson plans and materials developed by February 1996 with a stipend of $400 for satisfactory reports. It was a disappointment to only get 9 responses and not all of them demonstrating a satisfactory level of activity. Diana Marinez, Dean of Science at Texas A and M University, Corpus Christi, who is the other developer of this curriculum and the author reviewed the submitted materials and chose those showing the most promise to be invited to participate in the Summer Writing Workshop. Spring of 1996 and particularly in May--June, the author wrote a partial first draft of a companion volume for the teacher`s manual which would provide a rationale for doing culturally relevant science, present the cultural and the scientific background that teachers would need in order to be able to teach. One of the goals of this curriculum is that it should be off-the-shelf ready to teach and that teachers would not have to do extra research to encourage its adoption. The outline of the book is appendix 1. The Writing Workshop was held at Texas A and M University, Corpus Christi from July 14 to July 27, 1996. Participating teachers chose topics that they were interested in developing and wrote first drafts. These were distributed to all participants and critiqued by the workshop directors before being rewritten. Some teachers were more productive than others depending on their science background. In total an impressive number of lesson plans were written. These lesson plans are listed in Appendix 3. Appendix 4 is a sample lesson. Work still needs to be done on both the source book and the teachers` manual.

    The progress accomplished in the first five months of the three-year grant period of Teaching, Learning, and Planetary Exploration is presented. The objectives of this project are to discover new education products and services based on space science, particularly planetary exploration. An Exploration in Education is the umbrella name for the education projects as they are seen by teachers and the interested public. As described in the proposal, our approach consists of: (1) increasing practical understanding of the potential role and capabilities of the research community to contribute to basic education using new discoveries; (2) developing an intellectual framework for these contributions by supplying criteria and templates for the teacher's stories; (3) attracting astronomers, engineers, and technical staff to the project and helping them form productive education partnerships for the future, (4) exploring relevant technologies and networks for authoring and communicating the teacher's stories; (5) enlisting the participation of potential user's of the teacher's stories in defining the products; (6) actually producing and delivering many educationally useful teacher's stories; and (7) reporting the pilot study results with critical evaluation. Technical progress was made by assembling our electronic publishing stations, designing electronic publications based on space science, and developing distribution approaches for electronic products. Progress was made addressing critical issues by developing policies and procedures for securing intellectual property rights and assembling a focus group of teachers to test our ideas and assure the quality of our products. The following useful materials are being produced: the TOPS report; three electronic 'PictureBooks'; one 'ElectronicArticle'; three 'ElectronicReports'; ten 'PrinterPosters'; and the 'FaxForum' with an initial complement of printed materials. We have coordinated with planetary scientists and astronomers

    2010-07-01

    Traditionally in the center of interest on quantum physics referring to schools the question lies, whether electrons and photons are now particles or waves, a question, which is often characterized by the phrase ''wave-particle dualism'', which notoriously not exists in its original meaning. Against that by the author - basing on important preparatory works of Kueblbeck and Mueller - a new concept for the treatment of quantum physics for the school was proposed, which puts ''basic facts'' in the foreground, comparable with the Kueblbeck-Mueller ''characteristic features''. The ''basic facts'' are similar to axioms of quantum physics, by means of which a large number of experiments and phenomena can be ''explained'' at least qualitatively - in a heuristic way -. Instead of the so-called ''wave-particle dualism'' here uncertainty and complementarity are put in the foreground. The new concept is in the Internet under http://www.forphys.de extensively presented with many further materials. In the partial volumes of this publication manifold and carefully elaborated teaching materials are presented, by means of which scholars can get themselves the partial set of quantum physics referring to schools by different methods like learn at stations, short referates, Internet research, group puzzle, the query-sheet or the card-index method etc. In the present 2. part materials for the ''basic facts'' of quantum physics are prepared, by which also modern experiments can be interpreted. Here deals it with the getting of knowledge and application of the ''basic Facts''. This pursues also by real scholar experiments, simulations and analogy tests. The scholars obtain so more simply than generally a deeper insight in quantum physics.

    Full Text Available To improve the quality of English education in Nanggroe Aceh Darussalam (NAD, the Department of Education of NAD as policymaker has made some efforts, among others, sending some teachers for overseas training and also conducting in-service training in designing English teaching material. One of the results of the projects done by the Department of Education of NAD is an English textbook entitled “English in Context for SMA/MA student year 1”, was distributed to some senior high schools in Banda Aceh in 2005. Lately, the textbook hasn’t been used effectively. Based on that fact, it is considered necessary to evaluate the textbook in order to know its relevant to curriculum used. The data of this study are the contents of English in Context for SMA/MA students year 1, consist of objectives of the textbook, themes chosen, skills presented, task designed, types of the text, language focus provided, vocabulary, and just for fun sections as well as the physical condition of textbook. After the data were put based on their classifications, they were analyzed qualitatively by finding its relevancy to CBC. The relevant elements of textbook to CBC and the deficient element of the textbook were explained descriptively. The result shows that only small portions of suggested material in CBC are provided in the textbook. The types of listening texts which are relevant to CBC are only recount and report. The genre of the reading texts which are relevant to CBC are recount, report, and news items. Meanwhile, the speaking task types provided in the textbook are dialogue, talks/speeches, plays/role play, discussion, and report. The deficient elements found in the textbook are lack of clarity of the authors’ objective, repetition of the tasks designed, lack of variation in some skill’s presentation and some irrelevant materials to CBC.

    The illustrated case reports in this teaching atlas cover practically the entire range of possible pathological changes and are based on in-patient case material and 80,000 screening documents. The two basic approaches, - detection and analysis of changes -, are taught comprehensively and in great detail. A systematic procedure for analysing the mammographies, in order to detect even the very least changes, and its practical application is explained using mammographies showing unclear findings at first sight. A system of coordinates is presented which allows precise localisation of the changes. Exercises for practising the technique of identifying the pathological changes round up the methodolical chapters. Additional imaging technical enhancements and detail enlargements are of great help in interpreting the findings. The specific approach adopted for this teaching atlas is a 'reverse procedure', which leaves the beaten track and starts with analysing the mammographies and evaluating the radiographic findings, in order to finally derive the diagnosis.

Faculty resources designed for peer evaluation of classroom teaching are often inadequate for evaluating online teaching. The authors describe development, evaluation, and utility of a new peer evaluation form for formative assessment of online teaching deemed relevant, sound, feasible, and beneficial.

    Full Text Available History is an important school subject which conveys invaluable lessons from the past and whose worth transcends regional, national and cultural boundaries. Such a subject needs to be taught well in order to make learners gain deep appreciation of the relevance of their learning. However, effective teaching of history in Ghanaian schools has long been blighted by problems and challenges that have often gone unaddressed. With little empirical literature emerging from Ghana, this study, drawing on 32 history teachers from 18 senior high schools, examined history teachers’ perceptions of the problems faced in the teaching of history in the Cape Coast metropolis and Komenda, Edina, Eguafo, Abrim district in the Central Region of Ghana. The descriptive cross-sectional research design was used for the study and data were collected through questionnaires. The study found that overloaded syllabus, insufficient human and material resources, lack of support for the subject and large classes were the major problems facing the teaching of history. Based on the findings, the study concluded that the problems confronting the teaching of history in the two districts are administrative and pedagogical in nature. On this conclusion, it was recommended, among others, that syllabus content should be integrated to make it sync with the period given for its implementation. Also, the necessary resources should be provided to enhance the teaching of the subject.

    This article reviews methods used to teach psychopharmacology to psychiatry residents that utilize principles of adult learning, enlist active participation of residents, and provide faculty with skills to seek, analyze, and use new information over the course of their careers. The pros and cons of five "nonlecture" methods of teaching are reviewed: 1) journal clubs, 2) problem-based learning, 3) formalized patient-centered training, 4) games, and 5) the use of modern technology. Several programs are beginning to find novel methods of teaching psychopharmacology that are effective and well received by trainees and faculty. Programs need to go beyond the traditional lecture and apprenticeship model of psychopharmacology education to help make learning more fun, useful, relevant and self-sustaining.

    Different multimedia tools have been developed to help medical students prepare for the National Ranking Examination (NRE), rendering their choice quite difficult. No study has specifically evaluated students' expectations regarding these materials. To learn how medical students in Dijon assessed a website dedicated to cardiovascular rehabilitation, and collecting their suggestions in order to meet their expectations and the goals of second cycle medical studies. Eighteen second-cyle students were evaluated in a semi-directed manner and in ecological situation, a website specifically designed for the national curricula on cardiovascular rehabilitation for obtaining the Diploma of Specialty Studies (DES) for physical medicine and rehabilitation (PM&R) residents. Students also had to fill out a pretest and a posttest (5 MCQs). The overall quality of the site was deemed satisfactory (65.6 ± 7.7 points/100). Medical information was considered better than non-medical data and site's design (respectively 84.8 ± 8.1, 61.1 ± 20 and 64.4 ± 14.9/100). Students found the site useful in terms of understanding the items related to cardiovascular rehabilitation, although they judged it not completely in line with the NRE goals. The average score increased significantly between the pre-and post-test (6.8 ± 0.8 vs. 5 ± 1.5/8, plearning for the NRE. These elements could serve as building grounds for the future version of this website. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

    2007-01-01

    Basic Electromagnetism and Materials is the product of many years of teaching basic and applied electromagnetism. This textbook can be used to teach electromagnetism to a wide range of undergraduate science majors in physics, electrical engineering or materials science. However, by making lesser demands on mathematical knowledge than competing texts, and by emphasizing electromagnetic properties of materials and their applications, this textbook is uniquely suited to students of materials science. Many competing texts focus on the study of propagation waves either in the microwave or optical domain, whereas Basic Electromagnetism and Materials covers the entire electromagnetic domain and the physical response of materials to these waves. Professor André Moliton is Director of the Unité de Microélectronique, Optoélectronique et Polymères (Université de Limoges, France), which brings together three groups studying the optoelectronics of molecular and polymer layers, micro-optoelectronic systems for teleco...

    Full Text Available Based on the concept of needs analysis as proposed by Hutchinson and Waters (1987, this article discusses some aspects of English teaching in professional contexts in Brazil. We start with a brief historical view of needs analysis in order to discuss its application to teaching English for specific business purposes in professional contexts and its role for the instructor teaching in-company classes. We also aim to discuss the importance of needs analysis and its relation to the business area, as well as other features related to teaching in these contexts and its relevance to the professionals involved with business English teaching.

    From a noted specialist in astronomy education and outreach, this Brief provides an overview of the most influential discipline-based science education research literature now guiding contemporary astronomy teaching. In recent years, systematic studies of effective and efficient teaching strategies have provided a solid foundation for enhancing college-level students’ learning in astronomy. Teaching astronomy and planetary science at the college-level was once best characterized as professor-centered, information-download lectures. Today, astronomy faculty are striving to drastically improve the learning environment by using innovative teaching approaches.  Uniquely, the authors have organized this book around strands of commonly employed astronomy teaching strategies to help readers, professors, and scholars quickly access the most relevant work while, simultaneously, avoiding the highly specialized, technical vocabulary of constructivist educational pedagogies unfamiliar to most astronomy professors. F...
