  7. A New Approach to Authoring Interactive Curricular Material

    Science.gov (United States)

    Christian, Wolfgang

    1999-11-01

    A persistent problem facing educational software authors is that programming has no top. In other words, the moment a program is finished a potential user will ask for an enhancement or modification to use the program in a new context. Scriptable general-purpose applets, such as Physlets, provide a partial solution since the user can specify the applet's behavior provided that the applet author has anticipated the need. But this is not enough. Curriculum authors usually want to process the data and to present it in various formats. Over the past year the functionality of Physlets has been greatly extended through the use of inter-applet communication. This makes it possible to use a modular object-oriented approach for the design of interactive curricular material. Many Physlets, including Animator, EField, BField, and Faraday, are now capable of generating data in response to an internal clock or in response to user actions. This data can then be passed to a bar graph, a table of numeric values, or an x-y graph using one line of JavaScript to establish the communication link. This technique is very flexible since the code to process and present the data is written in an interpreted runtime environment. Furthermore, web servers can customize the code as the document is being delivered for applications such as testing and online homework. Examples of interactive curricular material that makes use of these techniques will be presented.

  8. A New Approach to Authoring Interactive Curricular Material

    2001-10-01

    It is still not common to find computer-based interactive material incorporated into mainstream teaching. Learning the intricacies of a software package is a poor investment of time if the half-life of the textbook is longer than the half-life of the computer technology. Internet technologies are likely to change this situation. This talk describes a set of Java applets, known as Physlets, which make use of these technologies. Physlets are designed to communicate with browsers by employing a scripting language such as JavaScript, thereby allowing one applet to be used in many different contexts. This approach makes it possible to use a modular object-oriented approach for the design of material. But this is not enough. Effective curriculum development must couple our software design philosophy with research into the effectiveness of computer-based instruction. Examples of Physlet-based curricular material will be presented.

    2014-07-01

    There is an imminent shortage of skilled workforce facing Europe's hi-tech industries mainly due to the declining interest of young people in science and engineering careers. To avert this trend the European Union funded the development of the `Photonics Explorer' - an intra-curricular educational kit designed to engage, excite and educate students about the fascination of working with optics hands-on, in their own classrooms! Each kit equips teachers with class sets of experimental components provided within a supporting didactic framework based on guided inquiry based learning techniques. The material has been specifically designed to integrate into the curriculum and enhance and complement the teaching and learning of science in the classroom. The kits are provided free of charge to teachers, in conjunction with teacher training courses. The main challenge of this program was the development of educational material that seamlessly integrates into the various national curricula across Europe. To achieve this, the development process included a preparatory EU wide curricula survey and a special `Review and Revise' process bringing together the expertise of over 35 teachers and pedagogic experts. This paper reports on the results of the preparatory study which identified two specific age groups at secondary schools for photonics educational material, the didactic content of the Photonics Explorer kit resulting from a pan-European collaboration of key stakeholders, EU wide dissemination and sustainability of the program.

  12. Transforming Spatial Reasoning Skills in the Upper-Level Undergraduate Geoscience Classroom Through Curricular Materials Informed by Cognitive Science Research

    Spatial visualization is an essential skill in the STEM disciplines, including the geosciences. Undergraduate students, including geoscience majors in upper-level courses, bring a wide range of spatial skill levels to the classroom. Students with weak spatial skills may be unable to understand fundamental concepts and to solve geological problems with a spatial component. However, spatial thinking skills are malleable. As a group of geoscience faculty members and cognitive psychologists, we have developed a set of curricular materials for Mineralogy, Sedimentology & Stratigraphy, and Structural Geology courses. These materials are designed to improve students' spatial skills, and in particular to improve students' abilities to reason about spatially complex 3D geological concepts and problems. Teaching spatial thinking in the context of discipline-based exercises has the potential to transform undergraduate STEM education by removing one significant barrier to success in the STEM disciplines. The curricular materials we have developed are based on several promising teaching strategies that have emerged from cognitive science research on spatial thinking. These strategies include predictive sketching, making visual comparisons, gesturing, and the use of analogy. We have conducted a three-year study of the efficacy of these materials in strengthening the spatial skills of students in upper-level geoscience courses at three universities. Our methodology relies on a pre- and post-test study design, with several tests of spatial thinking skills administered at the beginning and end of each semester. In 2011-2012, we used a "business as usual" approach to gather baseline data, measuring how much students' spatial thinking skills improved in response to the existing curricula. In the two subsequent years we have incorporated our new curricular materials, which can be found on the project website: http://serc.carleton.edu/spatialworkbook/activities.html Structural Geology

  13. InTeGrate's model for developing innovative, adaptable, interdisciplinary curricular materials that reach beyond the geosciences

    InTeGrate is NSF's STEP Center in the geosciences. A major goal of the project is to develop curricula that will increase the geoscience literacy of all students such that they are better positioned to make sustainable decisions in their lives and as part of the broader society. This population includes the large majority of students that do not major in the geosciences, those historically under-represented in the geosciences, and future K-12 teachers. To achieve this goal, we established a model for the development of curricular materials that draws on the distributed expertise of the undergraduate teaching community. Our model seeks proposals from across the higher education community for courses and modules that meet InTeGrate's overarching goals. From these proposals, we select teams of 3-5 instructors from three or more different institutions (and institution types) and pair them with assessment and web experts. Their communication and development process is supported by a robust, web-based content management system (CMS). Over two years, this team develops materials that explicitly address a geoscience-related societal challenge, build interdisciplinary problem-solving skills, make use of real geoscience data, and incorporate geoscientific and systems thinking. Materials are reviewed with the InTeGrate design rubric and then tested by the authors in their own courses, where student learning is assessed. Results are reviewed by the authors and our assessment team to guide revisions. Several student audiences are targeted: students in general education and introductory geoscience courses, pre-service K-12 teachers, students in other science and engineering majors, as well as those in the humanities and social sciences. Curriculum development team members from beyond the geosciences are critical to producing materials that can be adopted for all of these audiences, and we have been successful in engaging faculty from biology, economics, engineering, sociology

  14. Development, Implementation, and Assessment of Climate Curricular Materials for Introductory Undergraduates: Lessons Learned from the InTeGrate Project's Climate of Change Module

    Walker, B.; Fadem, C. M.; Shellito, L. J.

    2014-12-01

    Designing climate change curricular materials suitable for wide adoption across institutions and academic disciplines (including those outside of the geosciences) requires collaboration among faculty at different types of institutions and consideration of a variety of student populations, learning styles, and course formats. The Interdisciplinary Teaching of Geoscience for a Sustainable Future (InTeGrate) project, an NSF STEP Center program, provides opportunities for faculty to develop 2-3 week teaching modules to engage students in understanding the intersections between geoscience topics and societal issues. From 2012-2014, a team of 3 faculty from a liberal arts college, comprehensive university, and community college developed, implemented, assessed, and revised a 2-3 week module for introductory undergraduates entitled "Climate of change: interactions and feedbacks between water, air, and ice". The module uses authentic atmosphere, ocean, and cryosphere data from several regions to illustrate how climate impacts human societies and that the climate system has interacting components complicated by feedbacks, uncertainties, and human behavioral decisions. Students also consider past and present human adaptations to climate fluctuations. The module was piloted in introductory geology, meteorology, and oceanography courses during the 2012-2013 academic year, during which time formative and summative assessments were administered and used to modify the curricular materials. We will provide an overview of the module's content, instructional strategies involved in implementing the module, and methods of formative and summative assessment. We will also report on lessons learned during the development, piloting, revision, and publishing process, the importance of fostering partnerships between faculty from different institution types, and design approaches that promote widespread adoption of climate curricular materials.

  15. Systems, Society, Sustainability and the Geosciences: A Workshop to Create New Curricular Materials to Integrate Geosciences into the Teaching of Sustainability

    Gosselin, D. C.; Manduca, C. A.; Oches, E. A.; MacGregor, J.; Kirk, K. B.

    2012-12-01

    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

  17. Selection of material balance areas and item control areas

    International Nuclear Information System (INIS)

    1975-04-01

    Section 70.58, ''Fundamental Nuclear Material Controls,'' of 10 CFR Part 70, ''Special Nuclear Material,'' requires certain licensees authorized to possess more than one effective kilogram of special nuclear material to establish Material Balance Areas (MBAs) or Item Control Areas (ICAs) for the physical and administrative control of nuclear materials. This section requires that: (1) each MBA be an identifiable physical area such that the quantity of nuclear material being moved into or out of the MBA is represented by a measured value; (2) the number of MBAs be sufficient to localize nuclear material losses or thefts and identify the mechanisms; (3) the custody of all nuclear material within an MBA or ICA be the responsibility of a single designated individual; and (4) ICAs be established according to the same criteria as MBAs except that control into and out of such areas would be by item identity and count for previously determined special nuclear material quantities, the validity of which must be ensured by tamper-safing unless the items are sealed sources. This guide describes bases acceptable to the NRC staff for the selection of material balance areas and item control areas. (U.S.)

  19. Curricular improvements for entrepreneurial education

    Directory of Open Access Journals (Sweden)

    Vasilache Simona

    2017-07-01

    Full Text Available Our paper aims at investigating the most adequate methods for developing effective educational tools in entrepreneurial education. Entrepreneurship education should take place during the entire life of an entrepreneur, but the basic knowledge and skills related to this field are acquired starting from the elementary school, and improved during all the educational levels. Through entrepreneurship education, policymakers aim to prepare young people for succeeding on the entrepreneurial path. However, there are few scientific papers that aimed at discussing the available educational tools in Romania which play a role in forming entrepreneurs. Starting from the identified educational needs of young Romanian people under 35, including entrepreneurs and students, which were surveyed based on a questionnaire, we advance several key improvement areas for Romanian business curricula, and suggest critical paths to obtain desired results. The recommendations that we deliver through this paper are based on respondents’ opinions regarding their preference for certain aspects related to educational tools used in entrepreneurial education: learning materials used in universities in order to create an entrepreneurial mindset, the use of learning materials outside of the university curricula, and entrepreneurial skills that should be developed during school. A comparative perspective, examining curricular specificities in most entrepreneurial cultures of Europe, based on information obtained from Entrepreneurship Eurobarometer and Doing Business Indicators, is also included in our study. The main limitations, which arise from the subjective perspective of young entrepreneurs, as well as from the reduced sample volume, are thus corrected. The conclusions of our analysis provide a valuable starting point for educational policies promoting entrepreneurial skills enhancement in the Romanian business students’ population.

  1. International safeguards without material balance areas

    1992-01-01

    Recently altered perceptions of the role of the non-proliferation regime, as well as continued IAEA funding constraints, suggest a need to re-examine the fundamentals of IAEA verification strategy. This paper suggests that abandoning certain material balance area (MBA) related concepts that nominally form the basic framework of ''full-scope'' safeguards would result in a more flexible inspection regime. The MBA concept applied in the domestic context enables a national authority to localize losses in space and in time and to minimize the need to measure in-process inventory. However, these advantages do not accrue to an international verification regime because it cannot truly verify the ''flows'' between MBAs without extensive containment/surveillance measures. In the verification model studied, the entire nuclear inventory of a state is periodically declared and verified simultaneously in one or two large segments (containing possibly many MBAS). Simultaneous inventory of all MBAs within a segment would occur through advance ''mailbox'' declarations and random selection of MBAs for on-site verification or through enhanced containment/surveillance techniques. Flows are generally speaking not verified. This scheme would free the inspectorate from the obligation to attempt to verify on-site each stratum of the material balance of every facility declaring significant quantities of nuclear material

    2005-01-05

    The dynamic behavior of volatile organic compounds (VOCs) in indoor environments depends, in part, on sorptive interactions between VOCs in the gas phase and material surfaces. Since information on the types and quantities of interior material surfaces is not generally available, this pilot-scale study was conducted in occupied residences to develop and demonstrate a method for quantifying surface areas of objects and materials in rooms. Access to 33 rooms in nine residences consisting of bathrooms, bedroom/offices and common areas was solicited from among research group members living in the East San Francisco Bay Area. A systematic approach was implemented for measuring rooms and objects from 300 cm{sup 2} and larger. The ventilated air volumes of the rooms were estimated and surface area-to-volume ratios were calculated for objects and materials, each segregated into 20 or more categories. Total surface area-to-volume ratios also were determined for each room. The bathrooms had the highest total surface area-to-volume ratios. Bedrooms generally had higher ratios than common areas consisting of kitchens, living/dining rooms and transitional rooms. Total surface area-to-volume ratios for the 12 bedrooms ranged between 2.3 and 4.7 m{sup 2} m{sup -3}. The importance of individual objects and materials with respect to sorption will depend upon the sorption coefficients for the various VOC/materials combinations. When combined, the highly permeable material categories, which may contribute to significant interactions, had a median ratio of about 0.5 m{sup 2} m{sup -3} for all three types of rooms.

    2013-01-01

    In support of the Department of Energy’s continued plans to de-inventory and reduce the footprint of Cold War era weapons’ material production sites, the K-Area Material Storage (KAMS) facility, located in the K-Area Complex (KAC) at the Savannah River Site reservation, has expanded since its startup authorization in 2000 to accommodate DOE’s material consolidation mission. During the facility’s growth and expansion, KAMS will have expanded its authorization capability of material types and storage containers to allow up to 8200 total shipping containers once the current expansion effort completes in 2014. Recognizing the need to safely and cost effectively manage other surplus material across the DOE Complex, KAC is constantly evaluating the storage of different material types within K area. When modifying storage areas in KAC, the Documented Safety Analysis (DSA) must undergo extensive calculations and reviews; however, without an extensive and proven security posture the possibility for expansion would not be possible. The KAC maintains the strictest adherence to safety and security requirements for all the SNM it handles. Disciplined Conduct of Operations and Conduct of Projects are demonstrated throughout this historical overview highlighting various improvements in capability, capacity, demonstrated cost effectiveness and utilization of the KAC as the DOE Center of Excellence for safe and secure storage of surplus SNM.

  11. Merit exponents and control area diagrams in materials selection

    2011-01-01

    Highlights: → Merit exponents are introduced to generalise the merit indices commonly used in materials selection. → The merit exponents can rank materials in general design situations. → To allow identification of the active merit exponent(s), control area diagrams are used. → Principles for generating the control area diagrams are presented. -- Abstract: Merit indices play a fundamental role in materials selection, since they enable ranking of materials. However, the conventional formulation of merit indices is associated with severe limitations. They are dependent on the explicit solution of the variables in the equations for the constraints from the design criteria. Furthermore, it is not always easy to determine which the controlling merit index is. To enable the ranking of materials in more general design cases, merit exponents are introduced as generalisations of the merit indices. Procedures are presented for how to compute the merit exponents numerically without having to solve equations algebraically. Merit exponents (and indices) are only valid in a certain range of property values. To simplify the identification of the controlling merit exponent, it is suggested that so called control area diagrams are used. These diagrams consist of a number of domains, each showing the active constraints and the controlling merit exponent. It is shown that the merit exponents play a crucial role when the control area diagram (CAD) is set up. The principles in the paper are developed for mechanically loaded components and are illustrated for engineering beams with two or three geometric variables.

    A comprehensive search of the literature published between 2001 and 2010 was performed to gain a greater understanding of curricular reform practices at Chinese medical schools. There were 10,948 studies published between 2001 and 2010 that were retrieved from the database. Following preliminary screening, 76 publications from 49 different medical schools were selected. Thirty-one publications regarding clinical medicine curricular reforms were analyzed further. Of the 76 studies, 53 described curricular reforms that were instituted in theoretical courses, 22 described curricular reforms that were instituted in experimental courses, and 1 described curricular reforms that were instituted in a clinical skills training course. Of the 31 clinical medicine publications, 2 described reforms that were implemented for 3-year program medical students, 12 described reforms that were implemented for 5-year program medical students, 6 described reforms that were implemented for 7-year program medical students, and 2 described reforms that were implemented for 8-year program medical students. Currently, the majority of medical schools in China use the discipline-based curriculum model. Thirteen studies described transition to an organ-system-based curriculum model, 1 study described transition to a problem-based curriculum model, and 3 studies described transition to a clinical presentation-based curriculum model. In 7 studies educators decided to retain the discipline-based curriculum model while integrating 1 or several new courses to remedy the weaker aspects of the traditional curriculum, in 7 studies educators decided to integrate the preclinical courses with the clinical courses by using the systemic-integrating curricular system that dilutes classical disciplines and integrates material based on organ systems, and in 2 studies educators limited reforms to clinical courses only. Eight studies discussed the implementation of a formative evaluation system, 4 studies

  16. Material balance areas and frequencies for large reprocessing plants

    International Nuclear Information System (INIS)

    Burr, T.

    1994-01-01

    It has long been recognized that facilities with a large nuclear material throughput will probably not meet the International Atomic Energy Agency (IAEA) goal for detecting trickle diversion of plutonium over periods of about one year. The reason is that measurement errors for plutonium concentration and for liquid volume are often approximately relative over a fairly wide range of true values. Therefore, large throughput facilities will tend to have large uncertainties assigned to their annual throughput. By the same argument, if frequent balances are performed over small material balance areas, then the uncertainty associated with each balance period for each balance area will be small. However, trickle diversion would still be difficult to detect statistically. Because the IAEA will soon be faced with safeguarding a new large-scale reprocessing plant in Japan, it is timely to reconsider the advantages and disadvantages of performing frequent material balances over small balance areas (individual tanks where feasible). Therefore, in this paper the authors present some simulation results to study the effect of balance frequency on loss detection probability, and further simulation results to study possibilities introduced by choosing small balance areas. They conclude by recommending frequent balances over small areas

Aiming at spreading one of the actions carried out for the promotion of the inclusive educational practices in a municipal education system in a western city in the state of São Paulo, this paperwork has the objective of presenting an elaborated manual of orientations for the implementation of the individual curricular adaptations (ACIs for students who demand special educational necessities.(NEEs. The material was constituted on the basis of three data sets: 1 tabulation of the evaluations of the curricular adaptations already made; 2 the literature review; 3 analysis of the themes which have emerged during case discussion meetings mediated by the researchers with teachers from the Specialized Pedagogical Support Service (SAPE, with teachers and administrators from the common education system and the technical-pedagogical team. The final version of the manual contemplates the theoretical-operational aspects about the themes: flexibility and curricular adequation, inclusive education, definitions of NEEs, how SAPE works; and it finishes with a model proposal of ACI. It is expected that the spreading of this material can subside new curricular propositions for students with deficiency that are very distant from the academic level expected for the current scholar year.

    As a result of a pilot project developed at the old Spanish 'Junta de Energia Nuclear' to extract uranium from ores, tailings materials were generated. Most of these residual materials were sent back to different uranium mines, but a small amount of it was mixed with conventional building materials and deposited near the old plant until the surrounding ground was flattened. The affected land is included in an area under institutional control and used as recreational area. At the time of processing, uranium isotopes were separated but other radionuclides of the uranium decays series as 230 Th, 226 Ra and daughters remain in the residue. Recently, the analyses of samples taken at different ground's depths confirm their presence. This paper presents the methodology used to calculate the derived concentration level to ensure the reference dose level of 0.1 mSv y-1 used as radiological criteria. In this study, a radiological impact assessment was performed modelling the area as recreational scenario. The modelization study was carried out with the code RESRAD considering as exposure pathways, external irradiation, inadvertent ingestion of soil, inhalation of resuspended particles, and inhalation of outdoor radon ( 222 Rn). As result was concluded that, if the concentration of 226 Ra in the first 15 cm of soil is lower than, 0.34 Bq g-1 , the dose would not exceed the reference dose. Applying this value as a derived concentration level and comparing with the results of measurements on the ground, some areas with a concentration of activity slightly higher than latter were found. In these zones the remediation proposal has been to cover with a layer of 15 cm of clean material. This action represents a reduction of 85% of the dose and ensures compliance with the reference dose. (author)

This study investigates the objectives of communicative language teaching and curricular components of two important textbooks which are widely studied in Iran: the New Headway Advanced Series (2015, the Iran Language Institute (ILI Advanced1 (2008. The evaluation is done in terms of two prospects; firstly, the interpretation of communicative language teaching objectives and secondly, curricular components of the books. To this aim, a checklist of 5 Cs standards and seven curricular components evaluation developed by American Council on the Teaching of Foreign Languages (ACTFL was employed. The evaluation reveals that the New Headway advanced series is more preferable and desirable than the ILI Advanced 1 due to the design and organization, authenticity, attractiveness, functionality, practicality and the other qualities mentioned above regarding communication, cultures, connection, comparison, and community in all aspects. The evaluation based on the seven curricular components- language systems, communication strategies, cultural knowledge, learning strategies, content from other subject areas, critical thinking skills, technology and the other features- indicates that the ILI textbook enjoys low standards and is not well developed in all components. The ILI textbook is highly reading and writing oriented and not appropriate for transactional and interactional learning purposes. This study acquaints language teachers and learners with the more desirable and cogent book.

    Full Text Available Industrialization of electrofluidic devices requires both high performance coating laminates and efficient material utilization on large area substrates. Here we show that screen printing can be effectively used to provide homogeneous pin-hole free patterned amorphous fluoropolymer dielectric layers to provide both the insulating and fluidic reversibility required for devices. Subsequently, we over-coat photoresist using slit coating on this normally extremely hydrophobic layer. In this way, we are able to pattern the photoresist by conventional lithography to provide the chemical contrast required for liquids dosing by self-assembly and highly-reversible electrofluidic switching. Materials, interfacial chemistry, and processing all contribute to the provision of the required engineered substrate properties. Coating homogeneity as characterized by metrology and device performance data are used to validate the methodology, which is well-suited for transfer to high volume production in existing LCD cell-making facilities.

    Full Text Available The 21st century sets out new challenges to universities and university professors,who have to debate on the quality of education, the requirements on the teaching and learning, and the proposed curricula for the professional and disciplinary training in the university. In this context, research groups from four Colombian universities have developed a project in order to articulate therelationshipswithin the training of university professors, through the research of their practices and processes of curricular innovation. With such a goal the conformation of pedagogical collectives is promoted, and a reflective process about their pedagogical styles is generated (Callejas&,Corredor, 2002. Action research as a methodology and strategy of professional evelopment is proposed (McKernan, 1999, observation-reflection, planning-action, and then back to observation-reflection.Video recordings of classes, individual and group observation of the recordings, and individual and group interviews that favor reflection processes about the dimensions of the pedagogical style are performed. The analysis of the practice is guided by a complex, investigative and comprehensive vision of the curriculum that articulates theory and practice. The critical recognition that teachers do about their own pedagogical style favors the evolution of their ideas and guides them to start a process of curricular innovation.

    The material balance area (MBA) custodian has primary responsibility for control and accountability of nuclear material within an MBA. In this role, the custodian operates as an extension of the facility material control and accountability (MC ampersand A) organization. To effectively meet administrative requirements and protection needs, the custodian must be fully trained in all aspects of MC ampersand A related to the MBA, and custodian performance must be periodically evaluated. DOE Policy requires that each facility provide for a program which assures that each facility provide for a program which assures that personnel performing MC ampersand A functions are (1) trained and/or qualified to perform their duties and responsibilities and (2) knowledgeable of requirements and procedures related to their functions. The MBA Custodian Performance Evaluation Program at PNL uses a variety of assessment techniques to meet this goal, including internal and independent MBA audits, periodic custodian testing, conduct of limited scope performance tests, daily monitoring of MC ampersand A documentation, and reviewing custodian performance during physical inventories. The data collected from these sources is analyzed and incorporated into an annual custodian performance evaluation document, given to each custodian and line management. Development of this program has resulted in significantly improved custodian performance and a marked decrease in finding and observations identified during MBA audits

    As nuclear research has become more prevalent, environmental contamination from the disposal of radioactive waste has become a prominent issue. At Los Alamos National Laboratory (LANL) in northern New Mexico, radioactive contamination from disposal operations has raised some very specific concerns. Material Disposal Area G (Area G) is the primary low-level radioactive waste disposal site at LANL and occupies an area adjacent to land belonging to the Native American community of the Pueblo of San Ildefonso. Analyses of soil and vegetation collected from the perimeter of Area G have shown concentrations of radionuclides greater than background concentrations established for northern New Mexico.

    As nuclear research has become more prevalent, environmental contamination from the disposal of radioactive waste has become a prominent issue. At Los Alamos National Laboratory (LANL) in northern New Mexico, radioactive contamination from disposal operations has raised some very specific concerns. Material Disposal Area G (Area G) is the primary low-level radioactive waste disposal site at LANL and occupies an area adjacent to land belonging to the Native American community of the Pueblo of San Ildefonso. Analyses of soil and vegetation collected from the perimeter of Area G have shown concentrations of radionuclides greater than background concentrations established for northern New Mexico. As a result, Pueblo residents had become concerned that contaminants from Area G could enter tribal lands through various ecological pathways. The residents specifically questioned the safety of consuming meat from elk and deer that forage near Area G and then migrate onto tribal lands. Consequently, this study addresses the uptake of 3 H, 90 Sr, tot U, 238 Pu, 239 Pu, 241 Am, and 137 Cs by elk (Cervus elaphus) and deer (Odocoileus hemionus) that forage around the perimeter of Area G and the associated doses to the animals and to humans who consume these animals. Radionuclide uptake by and internal dose to animals was estimated using equations modified from National Council on Radiological Protection Report 76. The Residual Radiation computer code was used to estimate the external dose to animals and the dose to humans consuming meat. Soil and water concentrations from the perimeter of Area G and from background regions in northern New Mexico were averaged over 4 years (1993--1996) and used as input data for the models. Concentration estimates generated by the model correspond to the concentration range measured in actual tissue samples from elk and deer collected at LANL. The highest dose estimates for both animals (0.028 mrad/d) and humans (0.072 mrem/y) were well below

    Concepts have been defined such as Shipment batch, Technological batch, and Accounting batch, it has been found that Shipment and Technological batches should be formed through the arrangement of group of measured Accounting batches. The strategy for nuclear material (NM) measurement based on the Accounting batch is shown to give a possibility to use the advantages for the accounting purposes: ensure safeguards of non-diversion of NM at quantitative (numerical) level, which is a higher grade of safeguards compared to the systems of accounting and control now in force of the US and EURATOM; ensure a guaranteed accuracy and reliability (confidence level) when making up NM balance in Material Balance Area (MBA) and at Federal level, which has been realized only in part in the NM control and accounting systems. Strategy of NM measurement for MBAs counting NM in bulk form has been proposed [ru

    Crystalline silicon forms the basis of just about all computing technologies on the planet, in the form of microelectronics. An enormous amount of research infrastructure and knowledge has been developed over the past half-century to construct complex functional microelectronic structures in silicon. As a result, it is highly probable that silicon will remain central to computing and related technologies as a platform for integration of, for instance, molecular electronics, sensing elements and micro- and nanoelectromechanical systems. Porous nanocrystalline silicon is a fascinating variant of the same single crystal silicon wafers used to make computer chips. Its synthesis, a straightforward electrochemical, chemical or photochemical etch, is compatible with existing silicon-based fabrication techniques. Porous silicon literally adds an entirely new dimension to the realm of silicon-based technologies as it has a complex, three-dimensional architecture made up of silicon nanoparticles, nanowires, and channel structures. The intrinsic material is photoluminescent at room temperature in the visible region due to quantum confinement effects, and thus provides an optical element to electronic applications. Our group has been developing new organic surface reactions on porous and nanocrystalline silicon to tailor it for a myriad of applications, including molecular electronics and sensing. Integration of organic and biological molecules with porous silicon is critical to harness the properties of this material. The construction and use of complex, hierarchical molecular synthetic strategies on porous silicon will be described.

In this sense the aspects that try to be incorporated are not something added, but yes novel from the moment in which is introduced a new perspective, and is avoided the risk, sometimes so mentioned, of the fact that the transversality appear subtly blurred. The transverse shafts under this new position will imply an important transformation of the curricular areas according to the expectations of the present times and the appropriateness to the possibilities of comprehension of the student. This will be thus, if the transverse approaches, that constitute the center of the current social preoccupations of the curricular areas, are converted into the kernel in connection with those which turns the programming of the curricular areas, those which will be converted then in the necessary instruments for the attainment of the wished purposes.

    Over half of American medical schools are currently engaged in significant curricular reform. Traditionally, evaluation of the efficacy of educational changes has occurred well after the implementation of curricular reform, resulting in significant time elapsed before modification of goals and content can be accomplished. We were interested in establishing a process by which a new curriculum could be reviewed and refined before its actual introduction. The University of California, San Francisco (UCSF) School of Medicine embarked upon a new curriculum for the class entering in September 2001. Two separate committees coordinated plans for curricular change. The Essential Core Steering Committee was responsible for the first two years of training, and the Integrated Clinical Steering Committee guided the development of the third-and fourth-year curriculum. Both groups operated under guidelines of curricular reform, established by the School's Committee on Curriculum and Educational Policy, that emphasized integration of basic, clinical, and social sciences; longitudinal inclusion of themes such as behavior, culture, and ethics; use of clinical cases in teaching; and inclusion of small-group and problem-based learning. In early 2001, the deans of education and curricular affairs appointed an ad hoc committee to examine the status of the first-year curriculum, which had been entirely reformulated into a series of new multidisciplinary block courses. This ad hoc committee was composed of students and clinical faculty members who had not been substantially involved in the detailed planning of the blocks. The charge to the committee was to critique the progress of individual courses, and the first year as a whole, in meeting the goals outlined above, and to make recommendations for improving the preparation of students for the clinical years. To accomplish these goals, the committee reviewed background planning documents; interviewed each course director using a

    Any teacher of physics is likely to consider super-curricular reading as an important strategy for successful students. However, there are many more ways to extend a student’s interest in a subject than reading books, and undirected reading (such as providing a long out of date reading list) is not likely to be as helpful as targeted or directed study. I present an approach to directing and supporting additional study pioneered at St Paul’s School in the last 2 years based on two significant steps: • Providing a large, searchable database of reading and other material such as podcasts rather than simply a reading list. • Encouraging students to visualise and plot their trajectory toward a specific goal using a graph

    This paper describes the program to stabilize nuclear materials, consistent with the Department of Energy Office of Environmental Management (EM) plan, Accelerating Cleanup: Paths to Closure. The program is managed by the Plutonium Stabilization and Disposition Focus Area, which defines and manages technology development programs to stabilize nuclear materials and assure their subsequent safe storage and final disposition. The scope of the Plutonium Stabilization and Disposition Focus Area (PFA) activities includes non-weapons plutonium materials, special isotopes, and other fissile materials. The PFA provides solutions to site-specific and complex wide technology issues associated with plutonium remediation, stabilization, and preparation for disposition. Our paper describes an important programmatic function of the Department of Energy nuclear materials stabilization program, including the tie-in of policy to research needs and funding for the nuclear materials disposition area. The PFA uses a rigorous systems engineering determination of technology needs and gaps, under the guidance of a Technical Advisory Panel, consisting of complex-wide experts. The Research and Development planning provides an example for other waste areas and should be of interest to Research and Development managers. The materials disposition maps developed by the PFA and described in this paper provide an evaluation of research needs, data gaps and subsequent guidance for the development of technologies for nuclear materials disposition. This paper also addresses the PFA prioritization methodology and its ability to forecast actual time to implementation

It is not obliged to measure the soil radioactivity of the sites that were formerly used as scientific or engineering institutes, or hospitals with a radioactive material control area. If the former institutes or hospitals made studies with radioactive materials before the enforcement of the law concerning prevention from radiation hazards due to isotopes and its detailed regulations, it is concluded that there was the period when the radioactive materials were not under management. If it is found that the radioactive materials were applied at the former site before the enforcement of the related laws and regulations, the radioactivity in the soil of the redeveloped area should be examined, which should be obliged by some laws or regulations.

  1. Area effect on galvanic corrosion of condenser materials with titanium tubes in nuclear power plants

    International Nuclear Information System (INIS)

    Hwang, Seong Sik; Kim, Joung Soo; Kim, Uh Chul

    1993-01-01

    Titanium tubes have recently been used in condensers of nuclear power plants since titanium has very good corrosion resistance to seawater. However, when it is connected to Cu alloys as tube sheet materials and these Cu alloys are connected to carbon steels as water box materials, it makes significant galvanic corrosion on connected materials. It is expected from electrochemical tests that the corrosion rate of carbon steel will increase when it is galvanically coupled with Ti or Cu in sea water and the corrosion rate of Cu will increase when it is coupled with Ti, of this couple is exposed to sea water for a long time. It is also expected that the surface area ratios, R 1 (surface area of carbon steel/surface area of Ti) and R 2 (surface area of carbon steel/surface area of Cu) are very improtant for the galvanic corrosion of carbon steel and that these should not be kept to low values in order to minimize the galvanic corrosion on the carbon steel of the water box. Immersed galvanic corrosion tests show that the corrosion rate of carbon steel is 4.4 mpy when this ratio is 10 -2 . The galvanic corrosion rate of this carbon steel is increased from 4.4 mpy to 13 mpy at this area ratio, 1, when this connected galvanic specimen is galvanically coupled with a Ti tube. This can be rationalized by the combined effects of R 1 and R 2 on the polarization curve. (Author)

  2. Model to predict radiological consequences of transportation accidents involving dispersal of radioactive material in urban areas

    International Nuclear Information System (INIS)

    Taylor, J.M.; Daniel, S.L.

    1978-01-01

    The analysis of accidental releases of radioactive material which may result from transportation accidents in high-density urban areas is influenced by several urban characteristics which make computer simulation the calculational method of choice. These urban features fall into four categories. Each of these categories contains time- and location-dependent parameters which must be coupled to the actual time and location of the release in the calculation of the anticipated radiological consequences. Due to the large number of dependent parameters a computer model, METRAN, has been developed to quantify these radiological consequences. Rather than attempt to describe an urban area as a single entity, a specific urban area is subdivided into a set of cells of fixed size to permit more detailed characterization. Initially, the study area is subdivided into a set of 2-dimensional cells. A uniform set of time-dependent physical characteristics which describe the land use, population distribution, traffic density, etc., within that cell are then computed from various data sources. The METRAN code incorporates several details of urban areas. A principal limitation of the analysis is the limited availability of accurate information to use as input data. Although the code was originally developed to analyze dispersal of radioactive material, it is currently being evaluated for use in analyzing the effects of dispersal of other hazardous materials in both urban and rural areas

    The common marmoset ( Callithrix jacchus ) is one of the smallest species of primates, with high visual recognition abilities that allow them to judge the identity and quality of food and objects in their environment. To address the cortical processing of visual information related to material surface features in marmosets, we presented a set of stimuli that have identical three-dimensional shapes (bone, torus or amorphous) but different material appearances (ceramic, glass, fur, leather, metal, stone, wood, or matte) to anesthetized marmoset, and recorded multiunit activities from an area ventral to the superior temporal sulcus (STS) using multi-shanked, and depth resolved multi-electrode array. Out of 143 visually responsive multiunits recorded from four animals, 29% had significant main effect only of the material, 3% only of the shape and 43% of both the material and the shape. Furthermore, we found neuronal cluster(s), in which most cells: (1) showed a significant main effect in material appearance; (2) the best stimulus was a glossy material (glass or metal); and (3) had reduced response to the pixel-shuffled version of the glossy material images. The location of the gloss-selective area was in agreement with previous macaque studies, showing activation in the ventral bank of STS. Our results suggest that perception of gloss is an important ability preserved across wide range of primate species.

    Chemical and mineralogical characterization of waste materials present in an abandoned Pb, Zn–Ag mining site (SE, Spain) was carried out. In unaltered rocks, the mineralogy is characterized by plagioclase, pyroxene, magnetite, ilmenite, amphibole, biotite and quartz. Trace-element contents of these samples represent unaltered values. In mine-waste materials, pH ranged from acidic to slightly acidic and trace-element content was generally high, especially for Pb and Zn, although there were also substantial As concentrations. X-ray diffraction results suggested that these samples have a complex mineralogy, including alteration products. Surficial materials in the study area were affected by weathering processes, generating supergene assemblages, including Fe and Mn oxides and hydroxides, carbonates, hydrated sulfates and jarosite. Knowledge of the geochemical processes that took place in the past and which are still taking place provide an important tool for assessing associated environmental problems in this area.

    The challenges of producing and distributing the food necessary to feed an anticipated 9 billion people in developed and developing societies by 2050 without destroying Earth's finite soil and water resources present extremely complex problems that lack simple solutions. The ability of modern societies to adequately address these and other food-related problems will require an educated workforce trained not only in traditional food safety, security, and public health, but also in other areas including food production, sustainable practices, and ecosystem health. To help address the need for such an educated workforce, a curricular framework was developed to assist those tasked with designing education and training for future food systems workers. One sentence summary: A curricular framework for education and training in food safety and security was developed that incorporates One Health concepts. Copyright © 2015 The Authors.

    1996-07-01

    DOE facilities rely increasingly on computerized systems to manage nuclear materials accountability data and to protect against diversion of nuclear materials or other malevolent acts (e.g., hoax due to falsified data) by insider threats. Aspects of modern computerized material accountability (MA) systems including powerful personal computers and applications on networks, mixed security environments, and more users with increased knowledge, skills and abilities help heighten the concern about insider threats to the integrity of the system. In this paper, we describe a methodology for assessing MA applications to help decision makers identify ways of and compare options for preventing or mitigating possible additional risks from the insider threat. We illustrate insights from applying the methodology to local area network materials accountability systems

  15. A novel high specific surface area conducting paper material composed of polypyrrole and Cladophora cellulose.

    2008-10-02

    We present a novel conducting polypyrrole-based composite material, obtained by polymerization of pyrrole in the presence of iron(III) chloride on a cellulose substrate derived from the environmentally polluting Cladophora sp. algae. The material, which was doped with chloride ions, was molded into paper sheets and characterized using scanning and transmission electron microscopy, N 2 gas adsorption analysis, cyclic voltammetry, chronoamperometry and conductivity measurements at varying relative humidities. The specific surface area of the composite was found to be 57 m (2)/g and the fibrous structure of the Cladophora cellulose remained intact even after a 50 nm thick layer of polypyrrole had been coated on the cellulose fibers. The composite could be repeatedly used for electrochemically controlled extraction and desorption of chloride and an ion exchanging capacity of 370 C per g of composite was obtained as a result of the high surface area of the cellulose substrate. The influence of the oxidation and reduction potentials on the chloride ion exchange capacity and the nucleation of delocalized positive charges, forming conductive paths in the polypyrrole film, was also investigated. The creation of conductive paths during oxidation followed an effective medium rather than a percolative behavior, indicating that some conduction paths survive the polymer reduction steps. The present high surface area material should be well-suited for use in, e.g., electrochemically controlled ion exchange or separation devices, as well as sensors based on the fact that the material is compact, light, mechanically stable, and moldable into paper sheets.

  16. Study of LiFePO{sub 4} cathode materials coated with high surface area carbon

    LiFePO{sub 4} is a potential cathode material for 4 V lithium-ion batteries. Carbon-coated lithium iron phosphates were prepared using a high surface area carbon to react precursors through a solid-state process, during which LiFePO{sub 4} particles were embedded in amorphous carbon. The carbonaceous materials were synthesized by the pyrolysis of peanut shells under argon, where they were carbonized in a two-step process that occurred between 573 and 873 K. The shells were also treated with a proprietary porogenic agent with the goal of altering the pore structure and surface area of the pyrolysis products. The electrochemical properties of the as-prepared LiFePO{sub 4}/C composite cathode materials were systematically characterized by X-ray diffraction, scanning electron microscope, element mapping, energy dispersive spectroscopy, Raman spectroscopy, and total organic carbon (TOC) analysis. In LiFePO{sub 4}/C composites, the carbon not only increases rate capability, but also stabilizes capacity. In fact, the capacity of the composites increased with the specific surface area of carbon. The best result was observed with a composite made of 8.0 wt.% with a specific surface area of 2099 m{sup 2} g{sup -1}. When high surface area carbon was used as a carbon source to produce LiFePO{sub 4}, overall conductivity increased from 10{sup -8} to 10{sup -4} S cm{sup -1}, because the inhibition of particle growth during the final sintering process led to greater specific capacity, improved cycling properties and better rate capability compared to a pure olivine LiFePO{sub 4} material.

    1992-02-01

    A class of 9-10 year-olds (N = 12) in a British primary school were observed as it moved over a one-year period through three types of classroom environment, traditional directive, transitional negotiative and established negotiative. Each environment offered the children a differing relationship with curricular time, its control and allocation, moving from teacher-allocated time to child allocation. Pupil self-report and classroom observation indicated differences in the balance of curricular spread and allocated time on curricular subject in relation to the type of classroom organisation and who controlled classroom time. These differences were at both class and individual child level. The established negotiative environment recorded the most equitable curricular balance, traditional directive the least. While individual children responded differently within and across the three classroom environments, the established negotiative where time was under child control recorded preference for longer activity periods compared to where the teacher controlled time allocations.

    Bubbles generated during electro-delamination and chemical etch during large-area two-dimensional (2D) material transfer has been shown to cause rippling, and consequently, results in tears and wrinkles in the transferred film. Here, we demonstrate a scalable and reusable method to remove surface adhered micro-bubbles by using hydrophobic surfaces modified by self-assembled monolayers (SAMs). Bubble removal allows the 2D film to flatten out and prevents the formation of defects. Electrical characterization was used to verify improved transfer quality and was confirmed by increased field-effect mobility and decreased sheet resistance. Raman spectroscopy was also used to validate enhanced electrical quality following transfer. The bubble removal method can be applied to an assortment of 2D materials using diverse hydrophobic SAM variants. Our studies can be integrated into large scale applications and will lead to improved large-area 2D electronics in general.

    The US has far-reaching and extensive experience in the long-term management of areas contaminated with radioactive materials. This experience base includes the Department of Energy's continued follow-up with Hiroshima and Nagasaki from the 1940s at the Radiological Effects Research Foundation in Hiroshima, Japan, the long-term management of the Marshall Islands Programme, the clean-up of the US nuclear weapons complex and the ongoing management of accident sites such as in Palomares, Spain. This paper discusses the lessons learnt and best practices gained from this far-reaching and extensive experience in the long-term management of areas contaminated with radioactive materials.

  5. Radiological Modeling for Determination of Derived Concentration Levels of an Area with Uranium Residual Material - 13533

    As a result of a pilot project developed at the old Spanish 'Junta de Energia Nuclear' to extract uranium from ores, tailings materials were generated. Most of these residual materials were sent back to different uranium mines, but a small amount of it was mixed with conventional building materials and deposited near the old plant until the surrounding ground was flattened. The affected land is included in an area under institutional control and used as recreational area. At the time of processing, uranium isotopes were separated but other radionuclides of the uranium decay series as Th-230, Ra-226 and daughters remain in the residue. Recently, the analyses of samples taken at different ground's depths confirmed their presence. This paper presents the methodology used to calculate the derived concentration level to ensure that the reference dose level of 0.1 mSv y-1 used as radiological criteria. In this study, a radiological impact assessment was performed modeling the area as recreational scenario. The modelization study was carried out with the code RESRAD considering as exposure pathways, external irradiation, inadvertent ingestion of soil, inhalation of resuspended particles, and inhalation of radon (Rn-222). As result was concluded that, if the concentration of Ra-226 in the first 15 cm of soil is lower than, 0.34 Bq g{sup -1}, the dose would not exceed the reference dose. Applying this value as a derived concentration level and comparing with the results of measurements on the ground, some areas with a concentration of activity slightly higher than latter were found. In these zones the remediation proposal has been to cover with a layer of 15 cm of clean material. This action represents a reduction of 85% of the dose and ensures compliance with the reference dose. (authors)

    Full text: The United States has far-reaching experience in the long-term management of areas contaminated with radioactive materials. The events resulting from the atmospheric testing of nuclear weapons in the Marshall Islands, follow-up from Hiroshima and Nagasaki, accidents, and the environmental cleanup of our weapons complex have resulted in an extensive body of lessons learned and best practices. The lack of trust created in the affected population, regardless of cause of the spread of radioactive material, creates the working environment for long-term management of the situation. The extent of advanced planning for such an event will define and bound your ultimate success in reaching a conclusion acceptable to the affected parties. The two key issues to be addressed in the long-term management of areas contaminated with radioactive materials are the two 'T's' - technical and trust. The technical issues to be resolved include: access to the affected area; infrastructure to support operations; local and imported staffing; health care for the affected population; and payment to name a few. In addressing the issue of trust it is critical to establish open, honest and inclusive communications and decision making with the affected population and stakeholders, with clear roles and responsibilities defined. Actions must be sensitive to local cultural issues and agreements reached with affected populations prior to actions being taken. Establishment of an alternative views resolution process helps build trust and allow actions to taken. Government to government relations and agreements must be established with an acceptance and understanding of the long term investment in time and resources needed. Planning ahead for such an eventuality and putting in place procedures, agreements and resources needed to address the technical and trust issues associated with the long-term management of areas contaminated with radioactive materials enhances success.

    A small-laboratory fast-neutron generator and a large area detector were used to image hydrogen-bearing materials. The overall image resolution of 2.5 mm was determined by a knife-edge measurement. Contact images of objects were obtained in 5-50 min exposures by placing them close to a plastic scintillator at distances of 1.5 to 3.2 m from the neutron source. The generator produces 10{sup 9} n/s from the DD fusion reaction at a small target. The combination of the DD-fusion generator and electronic camera permits both small laboratory and field-portable imaging of hydrogen-rich materials embedded in high density materials.

    Radioactive material transport in urban areas is investigated and the specific urban features which influence environmental impacts are addressed. These features include the geographic and demographic make-up, and vehicular population and transportation patterns in the area. Previous efforts have not identified a most important population exposure pathway or group. This assessment examines several pathways and a number of urban specific population groups to evaluate their relative significance. In addition, because different causative events contribute to the overall environmental impacts, this assessment addresses four of these: incident free transport, vehicular accidents, human errors, and sabotage or malevolent acts. Not only does radioactive material transport produce radiological and economic consequences but also it can have social impacts. The objective of this study is to examine both the quantitative environmental impacts of radioactive material transport in urban areas and the more subjective social effects of this process. The social impacts assessment was performed by Battelle Human Affairs Research Centers, Seattle, Washington and their conclusions are only summarized here

    The objective of the Westchester Creek project was to evaluate proposed dredged material from this area to determine its suitability for unconfined ocean disposal at the Mud Dump Site. Westchester Creek was one of five waterways that the US Army Corps of Engineers- New York District (USACE-NYD) requested the Battelle/Marine Sciences Laboratory (MSL) to sample and evaluate for dredging and disposal in May 1995. The evaluation of proposed dredged material from the Westchester Creek project area consisted of bulk sediment chemical analyses, chemical analyses of dredging site water and elutriate, benthic acute and water-column toxicity tests, and bioaccumulation studies. Thirteen individual sediment core samples were collected from this area and analyzed for grain size, moisture content, and total organic carbon (TOC). One composite sediment sample representing the Westchester Creek area to be dredged, was analyzed for bulk density, specific gravity, metals, chlorinated pesticides, polychlorinated biphenyl (PCB) congeners, polynuclear aromatic hydrocarbons (PAHs), and 1,4-dichlorobenzene. Dredging site water and elutriate water, which is prepared from the suspended- particulate phase (SPP) of the Westchester Creek sediment composite, was analyzed for metals, pesticides, and PCBS.

  12. MINIMUM SOLID AREA MODELS FOR THE EFFECTIVE PROPERTIES OF POROUS MATERIALS - A REFUTATION

    Directory of Open Access Journals (Sweden)

    Willi Pabst

    2015-09-01

    Full Text Available Minimum solid area (MSA models are popular models for the calculation of the effective properties of porous materials and are frequently used to justify the use of a simple exponential relation for fitting purposes. In this contribution it is shown that MSA models, and the simple exponentials they support, are misleading and should be avoided. In particular, taking Young modulus and conductivity (thermal or electrical as examples, it is shown that MSA models are based on the unjustified (and unjustifiable hypothesis that the relative Young modulus and relative conductivity are identical, and moreover equal to the MSA fraction itself. This claim is generally false for isotropic materials, both random or periodic. Although indeed a very specific case exists in which this claim is true for the properties in one specific direction (viz., extremely anisotropic materials with translational invariance, in this specific case MSA models are redundant, because the relative properties are given exactly by the volume- or area-weighted arithmetic mean. It is shown that the mere existence of non-trivial cross-property relations is incompatible with the existence of MSA models. Finally, it is shown by numerical (finite-element modeling that MSA models provide incorrect results even in the simplest of the cases for which they were originally designed, i.e. for simple cubic packings of partially sintered isometric (initially spherical grains. Therefore, paraphrasing Box, MSA models are not only wrong, but also useless, and should be abandoned.

  13. Phase analysis of nano-phase materials using selected area electron diffraction in the TEM

    Labar, J. L.

    2002-01-01

    In analogy to X-ray power diffraction (XRD), we are developing a method to help phase identification when examining a large number of grains simultaneously by electron diffraction. Although XRD is well established, it can not be used for small quantities of materials (volumes below 1 mm 3 ). Examining a usual TEM sample with thickness of 100 nm and using a selected area of 1 mm in diameter, the selected area electron diffraction pattern (SAED) carries information about several thousands of grains from a material with an average grain size of about 10 nm. The accuracy of XRD can not be attained by electron diffraction (ED). However, simultaneous visual observation of the nanostructure is an additional benefit of TEM (beside the small amount of needed material). The first step of the development project was the development of a computer program ('ProcessDiffraction') that processes digital versions of SAED patterns and presents them in an XRD-like form (intensity vs. scattering vector). In the present version (V2.0.3) phase identification is carried out by comparing the measured distribution to 'Markers', i.e. data of known phases. XRD data cards are used if the detailed structure of a phase is not known. Kinematic electron diffraction intensities are calculated for phases with known atomic positions (Author)

    Sandia Laboratories is performing an environmental assessment for the Nuclear Regulatory Commission to ascertain the impacts produced by the transportation of radioactive materials near and through a large, densely populated area. Radiological, nonradiological and economic environmental impacts due to the transportation of all radioactive materials are considered, excepting those related to weapons, weapon components, or shipments on military vehicles. Although New York City is being studied initially to execute the methodology as a function of a real, complex urban environment, the assessment model developed is general in its basic content and is suitable for application to any urban area. Radiological consequences are being computed for cases involving ''normal'' and accident conditions. In the ''normal'' case, nothing unusual takes place, but small radiation doses are still received by nearby people. In the accident case, dispersion of possibly released material away from the accident site is considered. In addition, impacts due to deviations from quality assurance practices, as a result of human error, are being calculated using the assessment model in a special manner. Certain aspects of sabotage and diversion are also being investigated for an urban setting. Radiological consequences are being quantified in terms of human health effects and decontamination costs

    A preliminary investigation of possible sources of cement rock in the Taft area was made during the latter part of August 1968. Adequate deposits of limestone, clay, quartz conglomerate and sandstone, and pisolitic iron ore, yet no gypsum, were located to support a Cement plant should it prove feasible to establish one in this area. These materials, made up mostly of Tertiary and later sediments, crop out in isolated, inconspicuous low hills in a north- trending belt, 10 to 15 kilometers wide, lying about 90 kilometers to-the east of At Taft. The belt extends for more than 90 kilometers from the vicinity of Jabal 'An in the south to the crushed rock pits at Radwan and beyond in the north. The area is readily accessible either from the Talf-Riyadh highway or from the Taif-Bishah road presently under construction. The limestone, which is quite pure and dense in some localities but dolomitic, argillaceous, and cherty in others, occurs in a variety of colors and would make suitable decorative building stone. The volcanic rocks of the Harrat Hadan, lying directly to the east of the limestone belt, include volcanic ash beds some of which may have been altered to bentonitlc clays. Others may have been lithified and might be suitable for light-weight aggregate. These possibilities remain to be investigated. Precambrian metamorphic rocks lying directly to the south and southeast of Taif were also investigated as possible cement rock sources, but no suitable material was found here.

    Bamboo has been known as a sustainable material for architecture, but only used on a small scale for furniture. However, even though it a sustainable resource, many people considered Bamboo as outcast material for furniture because of its appearance. Evidently, the use of bamboo is often used to make simple tools with similar traditional designs for everyday life. The tradition of using bamboo was not further explored with respect to the ongoing development of creative design and function in the era of today’s modern technology. In retrospect to the above issues, this study is aimed to introduce the used of bamboo for material furniture in disaster and remote areas in Indonesia to increases their quality of life. It uses a research by a method of collecting data through surveys, literature review, interviews and training to determine the types of bamboo used for material furniture in disaster and remote territories. The results of this study is intended to show that the use of bamboo can be further developed into furniture for disaster and remote territory to create higher values of the products and increase the quality of life.

    Large-area parallel near-field optical nanopatterning on functional material surfaces was investigated with KrF excimer laser irradiation. A monolayer of silicon dioxide microspheres was self-assembled on the sample surfaces as the processing mask. Nanoholes and nanospots were obtained on silicon surfaces and thin silver films, respectively. The nanopatterning results were affected by the refractive indices of the surrounding media. Near-field optical enhancement beneath the microspheres is the physical origin of nanostructure formation. Theoretical calculation was performed to study the intensity of optical field distributions under the microspheres according to the light scattering model of a sphere on the substrate.

  19. An activated barrier for protection of special nuclear materials in vital areas

    1984-01-01

    The Argonne National Laboratory and Sandia National Laboratory have recently installed an activated barrier, the Access Denial System (ADS) for the upgrade of safeguards of special nuclear materials. The technology of this system was developed in the late 70's by Sandia National Laboratory-Albuquerque. The installation was the first for the Department of Energy. Subsequently, two additional installations have been completed. The Access Denial System, combined with physical restraints, provide the system delay. The principal advantages of the activated barrier are: (1) it provides an order of magnitude improvement in delay over that of a fixed barrier, (2) it can be added to existing vital areas with a minimum of renovations, (3) existing operations are minimally impacted, and (4) health and safety risks are virtually nonexistent. Hardening of the vital areas using the ADS was accomplished in a costeffective manner

    The frictional properties of a rough contact interface are controlled by its area of real contact, the dynamical variations of which underlie our modern understanding of the ubiquitous rate-and-state friction law. In particular, the real contact area is proportional to the normal load, slowly increases at rest through aging, and drops at slip inception. Here, through direct measurements on various contacts involving elastomers or human fingertips, we show that the real contact area also decreases under shear, with reductions as large as 30[Formula: see text], starting well before macroscopic sliding. All data are captured by a single reduction law enabling excellent predictions of the static friction force. In elastomers, the area-reduction rate of individual contacts obeys a scaling law valid from micrometer-sized junctions in rough contacts to millimeter-sized smooth sphere/plane contacts. For the class of soft materials used here, our results should motivate first-order improvements of current contact mechanics models and prompt reinterpretation of the rate-and-state parameters.

    Experimental investigations on the characteristic time of suppression of the thermal decomposition reaction of typical forest combustible materials (aspen twigs, birch leaves, spruce needles, pine chips, and a mixture of these materials) and the volume of water required for this purpose have been performed for model fire hotbeds of different areas: SFCM = 0.0003-0.007 m2 and SFCM = 0.045-0.245 m2. In the experiments, aerosol water flows with droplets of size 0.01-0.25 mm were used for the spraying of model fire hotbeds, and the density of spraying was 0.02 L/(m2·s). It was established that the characteristics of suppression of a fire by an aerosol water flow are mainly determined by the sizes of the droplets in this flow. Prognostic estimates of changes in the dispersivity of a droplet cloud, formed from large (as large as 0.5 L) "drops" (water agglomerates) thrown down from a height, have been made. It is shown that these changes can influence the conditions and characteristics of suppression of a forest fire. Dependences, allowing one to forecast the characteristics of suppression of the thermal decomposition of forest combustible materials with the use of large water agglomerates thrown down from an aircraft and aerosol clouds formed from these agglomerates in the process of their movement to the earth, are presented.

    To analyze curricular integration between teaching of patient safety and good infection prevention and control practices. Integrative review, designed to answer the question: "How does curricular integration of content about 'patient safety teaching' and content about 'infection prevention and control practices' occur in undergraduate courses in the health field?". The following databases were searched for primary studies: CINAHL, LILACS, ScienceDirect, Web of Science, Scopus, Europe PMC and MEDLINE. The final sample consisted of 13 studies. After content analysis, primary studies were grouped into two subject categories: "Innovative teaching practices" and "Curricular evaluation. Patient safety related to infection prevention and control practices is present in the curriculum of health undergraduate courses, but is not coordinated with other themes, is taught sporadically, and focuses mainly on hand hygiene.

  8. Curricular trends in Malaysian medical schools: innovations within.

    Various curricular innovations were adopted by medical schools worldwide in an attempt to produce medical graduates that could meet future healthcare needs of society locally and globally. This paper presents findings on curricular approaches implemented in Malaysian medical schools, in trying to meet those needs. Information was obtained from published records, responses from various questionnaires, personal communication and involvement with curricular development. Curricular innovations tended to be implemented in new medical schools upon their establishment. Established medical schools seemed to implement these innovations much later. Curricular trends appear to move towards integration, student-centred and problem-based learning as well as community-oriented medical education, with the Student-centred learning, Problem-based learning, Integrated teaching, Community-based education, Electives and Systematic programme (SPICES) model used as a reference. The focus is based on the premise that although the short-term aim of undergraduate medical education in Malaysia is to prepare graduates for the pre-registration house officer year, they must be able to practise and make decisions independently and be sensitive to the needs of the country's multiracial, multi-religious, and often remote communities. In most cases, curricular planning starts with a prescriptive model where planners focus on several intended outcomes. However, as the plan is implemented and evaluated it becomes descriptive as the planners reassess the internal and external factors that affect outcomes. A common trend in community-oriented educational activities is evident, with the introduction of interesting variations, to ensure that the curriculum can be implemented, sustained and the intended outcomes achieved.

    2005-01-01

    In recent years, a number of radioactive seizures have been increased (i.e. the materials that contain one or more radionuclides and their activities from the point of view of radiation protection are not negligible). This is mainly due to newly installed technical equipment that monitors metal scrap resp. communal waste during its entry to metallurgical plants and iron works resp. incinerators or waste dumps. In the Nuclear research Institute Rez plc. (NRI Rez) was established a working group which provides, among other activities, full system of radioactive material seizure assurance. Part of this service contents also transport, storage, treatment, conditioning and disposal of the seizured radioactive source. This service was firstly established for communal waste dump, but other organizations can take advantage of this service not only for the seizures in communal waste dumps. The system of radioactive material seizure assurance is consisted of the following parts: (1) seizure on stationary detection system; (2) 24 hours emergency service of the working group; (3) event classification, detailed counting a tracking of radioactive source; (4) found radioactive source transport to NRI Rez for storage; (5) radioactive source characterization; (6) seizure evaluation and protocol providing; (7) State Office for Nuclear Safety (SONS) decree about next procedure. Stationary detection system ( detection gate ) is usually installed at the entry to dumps area, metallurgical plants, iron works etc. The detection gate traces changes of vehicle dose rate comparing to the average background by vehicle measurement. If the vehicle dose rate is significantly higher then the average background (usual alarm level is 10-30% above background), the vehicle is postponed by the gate operator and put aside on the determined place. Seizure is announced to the police of the Czech republic and to the SONS. Typical examples of the seizured radionuclide sources are: military, devices coated

    A technical, defensible basis for the number and placement of air sampling instruments in a radioactive materials handling facility was developed. Historical air sampling data, process and physicochemical knowledge, qualitative smoke dispersion studies with video documentation, and quantitative trace gas dispersion studies were used to develop a strategy for number and placement of air samplers. These approaches can be used in other facilities to provide a basis for operational decisions. The requirements for retrospective sampling, personal sampling, and real-time monitoring are included. Other relevant operational decisions include selecting the numbers, placement, and appropriate sampling rates for instruments, identifying areas of stagnation or recirculation, and determining the adequacy and efficiency of any sampling transport lines. Justification is presented for using a graded approach to characterizing the workplace and determining air sampling and monitoring needs

    To determine whether a correlation exists between third-year PharmD students' perceived pharmacy knowledge and actual pharmacy knowledge as assessed by the Pharmacy Curricular Outcomes Assessment (PCOA). In 2010 and 2011, the PCOA was administered in a low-stakes environment to third-year pharmacy students at North Dakota State University College of Pharmacy, Nursing, and Allied Sciences (COPNAS). A survey instrument was also administered on which students self-assessed their perceived competencies in each of the core areas covered by the PCOA examination. The pharmacy students rated their competencies slightly higher than average. Performance on the PCOA was similar to but slightly higher than national averages. Correlations between each of the 4 content areas (basic biomedical sciences, pharmaceutical sciences, social/administrative sciences, and clinical sciences) mirrored those reported nationally by the National Association of Boards of Pharmacy (NABP). Student performance on the basic biomedical sciences portion of the PCOA was significantly correlated with students' perceived competencies in the biomedical sciences. No other correlations between actual and perceived competencies were significant. A lack of correlation exists between what students perceive they know and what they actually know in the areas of pharmaceutical science; social, behavioral, and administrative science; and clinical science. Therefore, additional standardized measures are needed to assess curricular effectiveness and provide comparisons among pharmacy programs.

    2017-09-01

    Full Text Available The analysis of the curricular design theories shows that the concept of performance has not yet been sufficiently studied, this explains actual inconsistencies in the design methodologies that claim to be focused on professional activity. However, in practice they are focusing professional problems instead, or simply copying other universities curricula without considering the particular country stage of development. Taking Chemical engineers as a referent point, the authors devise a methodology of curricular design focused on professional activity leading to the comprehension of this particular engineers ‘performance. The findings result from the application of the functional structural systemic method.

    Upgraded biodegradable piezoelectric composite materials elaborated by incorporation of Rochelle salt (RS, Sodium potassium tartrate tetrahydrate) in wood were reported. RS crystals, known as the first discovered piezoelectric material, were grown in the micro-cavities of wood, having naturally a tubular structure, by soaking the wood into RS saturated water. Since most of the cavities in wood are oriented in the same direction, the piezoelectric effect was improved when the cavities were filled by RS crystals. The mechanical, structural and piezoelectric properties of RS incorporated wood composite samples were characterized. Both direct and converse piezoelectric effects are illustrated. The wood-base composite exhibits an effective piezoelectric constant d 33 of 11 pC N-1. Also, the flexural strength and modulus of elasticity were enhanced by inserting RS into the wood, nevertheless the samples became more brittle. The wood-based piezoelectric samples prepared in this work can be used as actuators, sensors or energy harvesters. The process developed here permits us to manufacture large area piezoelectric devices which are environmentally and economically unsurpassed.

  15. TEMPERATURE PREDICTION IN 3013 CONTAINERS IN K AREA MATERIAL STORAGE (KAMS) FACILITY USING REGRESSION METHODS

    2008-01-01

    3013 containers are designed in accordance with the DOE-STD-3013-2004. These containers are qualified to store plutonium (Pu) bearing materials such as PuO2 for 50 years. DOT shipping packages such as the 9975 are used to store the 3013 containers in the K-Area Material Storage (KAMS) facility at Savannah River Site (SRS). DOE-STD-3013-2004 requires that a comprehensive surveillance program be set up to ensure that the 3013 container design parameters are not violated during the long term storage. To ensure structural integrity of the 3013 containers, thermal analyses using finite element models were performed to predict the contents and component temperatures for different but well defined parameters such as storage ambient temperature, PuO 2 density, fill heights, weights, and thermal loading. Interpolation is normally used to calculate temperatures if the actual parameter values are different from the analyzed values. A statistical analysis technique using regression methods is proposed to develop simple polynomial relations to predict temperatures for the actual parameter values found in the containers. The analysis shows that regression analysis is a powerful tool to develop simple relations to assess component temperatures

    Tunneling devices based on vertical heterostructures of graphene and other 2D materials can overcome the low on-off ratios typically observed in planar graphene field-effect transistors. This study addresses the impact of processing conditions on two-dimensional materials in a fully integrated heterostructure device fabrication process. In this paper, graphene-molybdenum disulfide-graphene tunneling heterostructures were fabricated using only large-area synthesized materials, unlike previous studies that used small exfoliated flakes. The MoS2 tunneling barrier is either synthesized on a sacrificial substrate and transferred to the bottom-layer graphene or synthesized directly on CVD graphene. The presence of graphene was shown to have no impact on the quality of the grown MoS2. The thickness uniformity of MoS2 grown on graphene and SiO2 was found to be 1.8 ± 0.22 nm. XPS and Raman spectroscopy are used to show how the MoS2 synthesis process introduces defects into the graphene structure by incorporating sulfur into the graphene. The incorporation of sulfur was shown to be greatly reduced in the absence of molybdenum suggesting molybdenum acts as a catalyst for sulfur incorporation. Tunneling simulations based on the Bardeen transfer Hamiltonian were performed and compared to the experimental tunneling results. The simulations show the use of MoS2 as a tunneling barrier suppresses contributions to the tunneling current from the conduction band. This is a result of the observed reduction of electron conduction within the graphene sheets.

    Any teacher of physics is likely to consider super-curricular reading as an important strategy for successful students. However, there are many more ways to extend a student's interest in a subject than reading books, and undirected reading (such as providing a long out of date reading list) is not likely to be as helpful as targeted or directed…

  7. Lessons from industry: one school's transformation toward "lean" curricular governance.

    Stratton, Terry D; Rudy, David W; Sauer, Marlene J; Perman, Jay A; Jennings, C Darrell

    2007-04-01

    As medical education grapples with organizational calls for centralized curricular oversight, programs may be compelled to respond by establishing highly vertical, stacked governance structures. Although these models offer discrete advantages over the horizontal, compartmentalized structures they are designed to replace, they pose new challenges to ensuring curricular quality and the educational innovations that drive the curricula. The authors describe a hybrid quality-assurance (QA) governance structure introduced in 2003 at the University of Kentucky College of Medicine (UKCOM) that ensures centralized curricular oversight of the educational product while allowing individualized creative control over the educational process. Based on a Lean production model, this approach draws on industry experiences that strategically separate institutional accountability (management) for a quality curriculum from the decision-making processes required to ensure it (production). In so doing, the authors acknowledge general similarities and key differences between overseeing the manufacture of a complex product versus the education of a physician-emphasizing the structured, sequential, and measurable nature of each process. Further, the authors briefly trace the emergence of quality approaches in manufacturing and discuss the philosophical changes that accompany transition to an institutional governance system that relies on vigorous, robust performance measures to offer continuous feedback on curricular quality.

    Undergraduate students from the health area often handle piercing-cutting instruments in their academic activities, which exposes them to the risk of contracting infections. This study aimed to analyze accidents with biological material among these students. Out of 170 accidents registered, 83 (48.8%) occurred with Dentistry students, 69 (40.6%) with Medical students, 11 (6.5%) with Nursing students and in 06 (3.5%) of the cases there was no such information in the files. Most accidents, 106 (62.4%), occurred with students from private schools and 55 (32.3%) with those from public schools. Percutaneous accidents occurred in 133 (78.2%) exposures and there was immediate search for specialized health care in only 38 (21.3%) accidents. In 127 (74.7%) accidents, the immunization schedule against hepatitis B was complete. Therefore, schools need to offer courses and specific class subjects regarding biosafety measures, including aspects related to immunization, especially the vaccine against hepatitis B.

  13. Curricular Review and Renewal at Massey University: A Process to Implement Improved Learning Practices.

    Science.gov (United States)

    Parkinson, Tim J; Weston, Jenny F; Williamson, Norman B

    Curriculum managers of the Bachelor of Veterinary Science program at Massey University have undertaken major curricular review every 5-10 years and also made adjustments to the program as a result of student and other stakeholder feedback. New curricula introduced in 2003 and 2013 aimed to address specific stakeholder requirements in the veterinary, agricultural, and allied industries. The new curricula initially sought to strengthen clinical skills but more recently focused on the core professional skill of client communication, the integration of knowledge and clinical skills, and a better understanding of the effects of herd health interventions on farm economics. The need for greater emphasis on the veterinarian's role in One Health at the intersection of humans, animals, and the environment was also recognized. The most recent curricular review was preceded by faculty enlightenment and discussion about innovative models of medical education with a focus on student-centered and integrated learning. A new curriculum was introduced from 2013 that presented more material in its clinical context, attempted to manage curriculum overload through a focus on Day One Competences, implemented vertical and horizontal integration of subjects, and introduced more problem-based and student-centered learning. Regular reviews of student workload were needed to ensure that the objectives were achieved, but student feedback has generally been positive.

  14. Preparations for Retrieval of Buried Waste at Material Disposal Area B

    Material Disposal Area B, a hazard category 3 nuclear facility, is scheduled for excavation and the removal of its contents. Wastes and excavated soils will be characterized for disposal at approved off-site waste disposal facilities. Since there were no waste disposal records, understanding the context of the historic operations at MDA B was essential to understanding what wastes were disposed of and what hazards these would pose during retrieval. The operational history of MDA B is tied to the earliest history of the Laboratory, the scope and urgency of World War II, the transition to the Atomic Energy Commission in January 1947, and the start of the cold war. A report was compiled that summarized the development of the process chemistry, metallurgy, and other research and production activities at the Laboratory during the 1944 to 1948 time frame that provided a perspective of the work conducted; the scale of those processes; and the handling of spent chemicals and contaminated items in lieu of waste disposal records. By 1947, all laboratories had established waste disposal procedures that required laboratory and salvage wastes to be boxed and sealed. Large items or equipment were to be wrapped with paper or placed in wooden crates. Most wastes were placed in cardboard boxes and were simply piled into the active trench. Bulldozers were used to cover the material with fill dirt on a weekly basis. No effort was made to separate waste types or loads, or to compact the wastes under the soil cover. Using the historical information and a statistical analysis of the plutonium inventory, LANL prepared a documented safety analysis for the waste retrieval activities at MDA B, in accordance with DOE Standard 1120-2005, Integration of Environment, Safety, and Health into Facility Disposition Activities, and the provisions of 29 CFR 1910.120, Hazardous Waste Operations and Emergency Response. The selected hazard controls for the MDA B project consist of passive design

  15. Curricular priorities for business ethics in medical practice and research: recommendations from Delphi consensus panels.

    2014-11-15

    No published curricula in the area of medical business ethics exist. This is surprising given that physicians wrestle daily with business decisions and that professional associations, the Institute of Medicine, Health and Human Services, Congress, and industry have issued related guidelines over the past 5 years. To fill this gap, the authors aimed (1) to identify the full range of medical business ethics topics that experts consider important to teach, and (2) to establish curricular priorities through expert consensus. In spring 2012, the authors conducted an online Delphi survey with two heterogeneous panels of experts recruited in the United States. One panel focused on business ethics in medical practice (n = 14), and 1 focused on business ethics in medical research (n = 12). Panel 1 generated an initial list of 14 major topics related to business ethics in medical practice, and subsequently rated 6 topics as very important or essential to teach. Panel 2 generated an initial list of 10 major topics related to business ethics in medical research, and subsequently rated 5 as very important or essential. In both domains, the panel strongly recommended addressing problems that conflicts of interest can cause, legal guidelines, and the goals or ideals of the profession. The Bander Center for Medical Business Ethics at Saint Louis University will use the results of the Delphi panel to develop online curricular resources for each of the highest rated topics.

    Using the frameworks of transformational learning and situated learning theory, we developed a technology-enhanced professionalism curricular model to build a learning community aimed at promoting residents' self-reflection and self-awareness. The RAPR model had 4 components: (1) R ecognize : elicit awareness; (2) A ppreciate : question assumptions and take multiple perspectives; (3) P ractice : try new/changed perspectives; and (4) R eflect : articulate implications of transformed views on future actions. The authors explored the acceptability and practicality of the RAPR model in teaching professionalism in a residency setting, including how residents and faculty perceive the model, how well residents carry out the curricular activities, and whether these activities support transformational learning. A convenience sample of 52 postgraduate years 1 through 3 internal medicine residents participated in the 10-hour curriculum over 4 weeks. A constructivist approach guided the thematic analysis of residents' written reflections, which were a required curricular task. A total of 94% (49 of 52) of residents participated in 2 implementation periods (January and March 2015). Findings suggested that RAPR has the potential to foster professionalism transformation in 3 domains: (1) attitudinal, with participants reporting they viewed professionalism in a more positive light and felt more empathetic toward patients; (2) behavioral, with residents indicating their ability to listen to patients increased; and (3) cognitive, with residents indicating the discussions improved their ability to reflect, and this helped them create meaning from experiences. Our findings suggest that RAPR offers an acceptable and practical strategy to teach professionalism to residents.

    Full Text Available Directrices Curriculares objetivan la organización de cursos y carreras para la constitución de identidades profesionales. En este sentido, las Directrices Curriculares Nacionales para la Enseñanza de Grado en Enfermería definen los fundamentos para la formación de enfermeras en el país, apuntando al tipo de conocimiento considerado importante en la profesión. Nos apoyamos en los presupuestos de la obra de Michel Foucault para realizar un análisis textual de los discursos difundidos por las Directrices Curriculares de Enfermería, problematizándolos como una estrategia de gobernar y de hacer subjetivo que actúa sobre los cuerpos de las futuras enfermeras. Las reflexiones apuntan a un documento que se puede ver como un instrumento que pretende normalizar a las alumnas y constituirlas para que se vuelvan enfermeras. Así se define el perfil de la "buena" y de la "mala" profesional, sistematizando los cuerpos y sus actitudes, sin permitirles que piensen y que hagan las cosas de otro modo e instituyendo un "régimen de verdades" que produce cierto tipo de enfermera.

    This study recruited 16 industrial workers to examine the effects of material, weight, and base area of container on reduction of grip force (ΔGF) and heart rate for a 100-m manual carrying task. This study examined 2 carrying materials (iron and water), 4 carrying weights (4.4, 8.9, 13.3, 17.8 kg), and 2 base areas of container (24 × 24 cm, 35 × 24 cm). This study showed that carrying water significantly increased ΔGF and heart rate as compared with carrying iron. Also, ΔGF and heart rate significantly increased with carrying weight and base area of container. The effects of base area of container on ΔGF and heart rate were greater in carrying water condition than in carrying iron condition. The maximum dynamic effect of water on ΔGF and heart rate occurred when water occupied ~60%-80% of full volume of the container.

    2009-01-21

    Careful processing of four representative metal-organic framework (MOF) materials with liquid and supercritical carbon dioxide (ScD) leads to substantial, or in some cases spectacular (up to 1200%), increases in gas-accessible surface area. Maximization of surface area is key to the optimization of MOFs for many potential applications. Preliminary evidence points to inhibition of mesopore collapse, and therefore micropore accessibility, as the basis for the extraordinarily efficacious outcome of ScD-based activation.

    This paper describes the investigation of heat impact on the vertical surfaces of buildings based on their thermal behavior. The study was performed based on four building materials that is commonly used in Malaysia; brick, concrete, granite and white concrete tiles. The thermal performances on the building materials were investigated using a surface temperature sensor, data logging system and infrared thermography. Results showed that the brick had the capability to absorb and store heat greater than other materials during the investigation period. The normalized heat (total heat/solar radiation) of the brick was 0.093 and produces high heat (51% compared to granite), confirming a substantial amount of heat being released into the atmosphere through radiation and convection. The most sensitive material that absorbs and stores heat was in the following order: brick > concrete > granite > white concrete tiles. It was concluded that the type of exterior wall material used in buildings had significant impact to the environment.

  6. Brittle materials at high-loading rates: an open area of research

    Science.gov (United States)

    2017-01-01

    Brittle materials are extensively used in many civil and military applications involving high-strain-rate loadings such as: blasting or percussive drilling of rocks, ballistic impact against ceramic armour or transparent windshields, plastic explosives used to damage or destroy concrete structures, soft or hard impacts against concrete structures and so on. With all of these applications, brittle materials are subjected to intense loadings characterized by medium to extremely high strain rates (few tens to several tens of thousands per second) leading to extreme and/or specific damage modes such as multiple fragmentation, dynamic cracking, pore collapse, shearing, mode II fracturing and/or microplasticity mechanisms in the material. Additionally, brittle materials exhibit complex features such as a strong strain-rate sensitivity and confining pressure sensitivity that justify expending greater research efforts to understand these complex features. Currently, the most popular dynamic testing techniques used for this are based on the use of split Hopkinson pressure bar methodologies and/or plate-impact testing methods. However, these methods do have some critical limitations and drawbacks when used to investigate the behaviour of brittle materials at high loading rates. The present theme issue of Philosophical Transactions A provides an overview of the latest experimental methods and numerical tools that are currently being developed to investigate the behaviour of brittle materials at high loading rates.

    To overcome certain limitations of contemporary materials used for bone tissue engineering, such as inflammatory response after implantation, a whole new class of materials based on polysaccharide compounds is being developed. Here, nanoparticulate bioactive glass reinforced gelan-gum (GG-BAG) has recently been proposed for the production of bone scaffolds. This material offers promising biocompatibility properties, including bioactivity and biodegradability, with the possibility of producing scaffolds with directly controlled microgeometry. However, to utilize such a scaffold with application-optimized properties, large sets of complex numerical simulations using the real microgeometry of the material have to be carried out during the development process. Because the GG-BAG is a material with intrinsically very low attenuation to X-rays, its radiographical imaging, including tomographical scanning and reconstructions, with resolution required by numerical simulations might be a very challenging task. In this paper, we present a study on X-ray imaging of GG-BAG samples. High-resolution volumetric images of investigated specimens were generated on the basis of micro-CT measurements using a large area flat-panel detector and a large area photon-counting detector. The photon-counting detector was composed of a 010× 1 matrix of Timepix edgeless silicon pixelated detectors with tiling based on overlaying rows (i.e. assembled so that no gap is present between individual rows of detectors). We compare the results from both detectors with the scanning electron microscopy on selected slices in transversal plane. It has been shown that the photon counting detector can provide approx. 3× better resolution of the details in low-attenuating materials than the integrating flat panel detectors. We demonstrate that employment of a large area photon counting detector is a good choice for imaging of low attenuating materials with the resolution sufficient for numerical

    To overcome certain limitations of contemporary materials used for bone tissue engineering, such as inflammatory response after implantation, a whole new class of materials based on polysaccharide compounds is being developed. Here, nanoparticulate bioactive glass reinforced gelan-gum (GG-BAG) has recently been proposed for the production of bone scaffolds. This material offers promising biocompatibility properties, including bioactivity and biodegradability, with the possibility of producing scaffolds with directly controlled microgeometry. However, to utilize such a scaffold with application-optimized properties, large sets of complex numerical simulations using the real microgeometry of the material have to be carried out during the development process.

    INTRODUCTION An assessment of known and undiscovered mineral resources of selected areas administered by the Bureau of Land Management (BLM) in Clark and Nye Counties, Nevada was conducted by the U.S. Geological Survey (USGS), Nevada Bureau of Mines and Geology (NBMG), and University of Nevada, Las Vegas (UNLV). The purpose of this work was to provide the BLM with information for use in their long-term planning process in southern Nevada so that they can make better-informed decisions. The results of the assessment are in Ludington (2006). Existing information about the areas, including geology, geophysics, geochemistry, and mineral-deposit information was compiled, and field examinations of selected areas and mineral occurrences was conducted. This information was used to determine the geologic setting, metallogenic characteristics, and mineral potential of the areas. Twenty-five Areas of Critical Environmental Concern (ACECs) were identified by BLM as the object of this study. They range from tiny (less than one km2) to large (more than 1,000 km2). The location of the study areas is shown on Figure 1. This report includes geochemical data for rock samples collected by staff of the USGS and NBMG in these ACECs and nearby areas. Samples have been analyzed from the Big Dune, Ash Meadows, Arden, Desert Tortoise Conservation Center, Coyote Springs Valley, Mormon Mesa, Virgin Mountains, Gold Butte A and B, Whitney Pockets, Rainbow Gardens, River Mountains, and Piute-Eldorado Valley ACECs.

    Building materials, collected from different sites in Ramsar, a northern coastal city in Iran, were analyzed for their natural radionuclide contents. The measurements were carried out using a high resolution high purity Germanium (HPGe) gamma-ray spectrometer system. The activity concentration of (226)Ra, (232)Th, and (40)K content varied from below the minimum detection limit up to 86,400 Bqkg(-1), 187 Bqkg(-1), and 1350 Bqkg(-1), respectively. The radiological hazards incurred from the use of these building materials were estimated through various radiation hazard indices. The result of this survey shows that values obtained for some samples are more than the internationally accepted maximum limits and as such, the use of them as a building material pose significant radiation hazard to individuals.

    The Yucca Mountain Waste Package Closure System (WPCS) cells provide for shielding of highly radioactive materials contained in unsealed waste packages. The purpose of the cells is to provide safe environments for package handling and sealing operations. Once sealed, the packages are placed in the Yucca Mountain Repository. Closure of a typical waste package involves a number of remote operations. Those involved typically include the placement of matched lids onto the waste package. The lids are then individually sealed to the waste package by welding. Currently, the waste package includes three lids. One lid is placed before movement of the waste package to the closure cell; the final two are placed inside the closure cell, where they are welded to the waste package. These and other important operations require considerable remote material handling within the cell environment. This paper discusses the remote material handling equipment, designs, functions, operations, and maintenance, relative to waste package closure

    A combination of Gaussian plume and particle-in-cell techniques is used to simulate the atmospheric transport and dispersion of a puff release of radioactive material. The release is caused by an accident that is assumed to occur during the shipment of the radioactive material through central New York City. The simulation provides estimates of volumetric and surface concentrations of the dispersed material that are used to predict radiation doses incurred by the City's population in the event of an accidental release. In the simulation, the release point is arbitrary and the material is assumed to be either a gas or fine particles. The Gaussian plume model follows cloud concentrations from the release time until times when transport over distances up to 500 m has been achieved. The released cloud may stabilize at street level or above the mean buildings height; at a street intersection or in the middle of the block. The possibility of the formation of multiple clouds, owing to circumstances of wind flow direction and street geometry, is allowed

    Full Text Available Groundwaters hydrochemistry of Ayrakan and Cheshmeh Shotori areas and geochemistry of rare earth elements, indicate Ayrakan alkali granite as the origin of uranium and other dissolved elements in groundwaters of these areas. Geochemical and hydrogeochemical studies as well as the trend of uranium and thorium transition and mobility in aqueous environments of these areas indicate uranium adsorption by iron hydroxide (goethite as the deterrent agent against uranium transition and mobility from depth to surface. Gamma-ray spectroscopic study of sediments from Cheshmeh Shotori area by HPGe detector indicates the presence of 226Ra in high contents and as the radioactive nuclide that is the reason for high activity of these sediments. Production of 226Ra from 238U decay, shorter half-life of 226Ra compared to 238U, radium transition by groundwaters from depth to surface as well as hydrogeochemical evidences, all suggest the possibility of existence of hidden uranium deposit and uranium mineralization in depth and the distance between Ayrakan and Cheshmeh Shotori areas.

    Full Text Available Tests for bioaccessibility are useful in human health risk assessment. No research data with the objective of determining bioaccessible arsenic (As in areas affected by gold mining and smelting activities have been published so far in Brazil. Samples were collected from four areas: a private natural land reserve of Cerrado; mine tailings; overburden; and refuse from gold smelting of a mining company in Paracatu, Minas Gerais. The total, bioaccessible and Mehlich-1-extractable As levels were determined. Based on the reproducibility and the accuracy/precision of the in vitro gastrointestinal (IVG determination method of bioaccessible As in the reference material NIST 2710, it was concluded that this procedure is adequate to determine bioaccessible As in soil and tailing samples from gold mining areas in Brazil. All samples from the studied mining area contained low percentages of bioaccessible As.

    As DOE continues to forge ahead and re-evaluate post cold war missions, facilities that were constructed and operated for DOE/DOD over the past 50+ years are coming to the end of their useful life span. These various facilities throughout the country had served a very useful purpose in our nations history; however, their time of Cold War materials production has come to an end. With this looming finalization comes a decision as to how to remedy their existence: D and R the facilities and return to ''Greenfield''; or, retrofit the existing facilities to accommodate the newer missions of the DOE Complex. The 105-K Reactor Building located at the Savannah River Site in Aiken, South Carolina was retrofit on an accelerated project schedule for a new mission called K-Area Materials Storage (KAMS). Modifications to the former defense reactor's building and equipment will allow storage of Plutonium from the Rocky Flats Site in Colorado and other materials deemed necessary by the Department of Energy. Proper project planning and activity sequencing allowed the DOE and the Westinghouse Savannah River Company to realize savings from: the recycling and/or reuse of modified facility components; reduction and reclassification of waste; reduction in radiological area footprint (rollbacks)

    The US has agreed to pursue cooperative nuclear Material Protection, Control and Accounting (MPC and A) programs with the Republic of Kazakstan. As part of this cooperation, a state system of control accounting and physical protection for nuclear materials is being developed. The US Department of Energy is providing assistance at the four nuclear sites in the Republic to enhance MPC and A systems, techniques, hardware, software, procedures, and training. US survey teams, which include both material control and accounting (MC and A) and physical protection experts, have visited four nuclear sites in Kazakstan. MPC and A assistance is being provided to the Ulba State Holding Company, the Institute of Atomic Energy at Kurchatov City and Ala Tau, and the Mangyshlak Atomic Energy Complex (MAEC) BN-350 nuclear power plant in Aktau. At these sites, the facility staffs and DOE technical teams are working together to identify conditions not completely conforming with accepted international standards, as well as potential enhancements to correct such conditions. Design packages for enhancements at each of these facilities are prepared in collaboration with Kazakstani specialists. After agreement is reached on the specifications by the US and Kazakstan, MPC and A equipment is procured and installed. This paper summarizes the approach to the cooperative programs at these facilities, program status, and future plans

  9. Analysis of glycerin waste in A-Area sanitary treatment facility material

    International Nuclear Information System (INIS)

    1995-01-01

    TNX has a large supply of 55 gallon drums containing pure glycerin and glycerin with additives. The glycerin drums were procured to simulate the glass stream in a pilot-scale melter process at TNX. Since the glycerin was not used for this process, TNX is looking at disposing the material in a sanitary waste treatment facility onsite. The effect of adding the contents of the drums to sewage bacteria was tested. A drum of pure glycerin and a drum of glycerin mixed with lithium chloride were tested. The test consisted of mixing sanitary sludge material with the glycerin material. The purpose of the test was to determine if the glycerin impacted the aerobic bacterial population. The bacterial densities were determined by taking samples from the sludge/glycerin mixtures and using aerobic plate count methods. The total organic carbon (TOC) levels were measured before and after testing. The results indicate that the cell density of the aerobic bacteria increased with the addition of glycerin and the glycerin mixture and the TOC removal rate was different for all tests. Disposal of glycerin in the wastewater treatment facilities should pose no problems. Additional testing and analysis of the mixed samples should be done before its disposal in a waste water treatment facility

    Full Text Available The hanging mark is the most relevant feature of hanging and its characteristics are well known in the literature. Most of the time, the ligature material is not available during autopsy examination in hanging. Hence, the features of the ligature material are not submitted to systematic analysis. However, the type and position of the knot plays an important role in the mechanism of death and autopsy findings in hanging. Out of the total hanging deaths, complete hanging was seen in 67.7% of the cases, but a typical hanging was noted in only 10.2% of the cases. The commonest type of ligature material used for ligation around the neck was nylon rope followed by odhni and jute rope. The fixed knot was noted in 64.6% of the cases and a running (slip in 21.3% of the cases. The commonest position of the knot was at nape of the neck, followed by the left side of the neck at mastoid process. The number of turns/loops of a ligature around the neck was one turn in 72.4% and two in 25.2% the hanging deaths. Most victims committed suicide by hanging in their homes, and the commonest ligature points were trees, flowed by beams and ceiling hook/fans.

    Until now, few sp2 carbon materials simultaneously exhibit superior performance for specific surface area (SSA) and electrical conductivity at bulk state. Thus, it is extremely important to make such materials at bulk scale with those two outstanding properties combined together. Here, we present a simple and green but very efficient approach using two standard and simple industry steps to make such three-dimensional graphene-based porous materials at the bulk scale, with ultrahigh SSA (3523 m2/g) and excellent bulk conductivity. We conclude that these materials consist of mainly defected/wrinkled single layer graphene sheets in the dimensional size of a few nanometers, with at least some covalent bond between each other. The outstanding properties of these materials are demonstrated by their superior supercapacitor performance in ionic liquid with specific capacitance and energy density of 231 F/g and 98 Wh/kg, respectively, so far the best reported capacitance performance for all bulk carbon materials.

    Subsequent to the 2008 E-Area Low-Level Waste Facility (ELLWF) Performance Assessment (PA) (WSRC 2008), two additional E-Area vault concrete property testing programs have been conducted (Dixon and Phifer 2010 and SIMCO 2011a) and two additional E-Area vault concrete durability modeling projections have been made (Langton 2009 and SIMCO 2012). All the information/data from these reports has been evaluated and consolidated herein by the Savannah River National Laboratory (SRNL) at the request of Solid Waste Management (SWM) to produce E-Area vault concrete hydraulic and physical property data and vault durability/degradation projection recommendations that are adequately justified for use within associated Special Analyses (SAs) and future PA updates. The Low Activity Waste (LAW) and Intermediate Level (IL) Vaults structural degradation predictions produced by Carey 2006 and Peregoy 2006, respectively, which were used as the basis for the 2008 ELLWF PA, remain valid based upon the results of the E-Area vault concrete durability simulations reported by Langton 2009 and those reported by SIMCO 2012. Therefore revised structural degradation predictions are not required so long as the mean thickness of the closure cap overlying the vaults is no greater than that assumed within Carey 2006 and Peregoy 2006. For the LAW Vault structural degradation prediction (Carey 2006), the mean thickness of the overlying closure cap was taken as nine feet. For the IL Vault structural degradation prediction (Peregoy 2006), the mean thickness of the overlying closure cap was taken as eight feet. The mean closure cap thicknesses as described here for both E-Area Vaults will be included as a key input and assumption (I&A) in the next revision to the closure plan for the ELLWF (Phifer et al. 2009).

Three investigative tendencies are prevalent: school practices, curricular and technology policies, and contemporary cultural dynamics and sociability. Finally, we seek to establish some investigative perspective in the field, as well as some investigative assumptions for the studies of school curricula and their contemporary policies.

  15. Aerial radiological survey of the Feed Materials Production Center and surrounding area, Fernald, Ohio. Date of survey: April 1985

    International Nuclear Information System (INIS)

    1985-10-01

    An aerial radiological survey was performed over the area surrounding the Feed Materials Production Center, located near Fernald, Ohio, during the period April 24 to 27, 1985. The survey covered a 70-square-kilometer (27-square-mile) area centered on the plant. The highest exposure rates, in excess of 0.35 milliroentgens per hour (mR/h), were inferred from the data measured directly over the plant. This radiation was due to the presence of nuclides which were consistent with normal plant operations. For the remainder of the survey area, the inferred radiation exposure rates, varying from 6 to 12 microroentgens per hour (μR/h), were due to naturally-occurring potassium, uranium, thorium, and daughter products. The reported exposure rate values include an estimated cosmic ray contribution of 3.7μR/h. Ground-based measurements, conducted during the time of the aerial survey, were compared to the aerial results. Pressurized ionization chamber readings and a group of soil samples were acquired at several locations within the survey area. The exposure rate values obtained from these measurements were in agreement with the inferred aerial results. Soil sample results showed several areas just outside the site boundary with slightly elevated amounts of U-238. The levels, however, were well below the detection limit of the aerial system. The only off-site area that showed apparent above background activity in the aerial data was directly west of the storage silos. The symmetric shape of the contours, however, suggests that these elevated levels are due to ''shine'' from material stored on-site in the silos and not to actual off-site contamination. Detailed comparison of the 1985 aerial survey data with a previous survey conducted in 1976 showed no significant change in any area outside the plant boundary. 6 refs., 9 figs., 3 tabs

    The transfer of chemical vapor deposited graphene is a crucial process, which can affect the quality of the transferred films and compromise their application in devices. Finding a robust and intrinsically clean material capable of easing the transfer of graphene without interfering with its properties remains a challenge. We here propose the use of an organic compound, cyclododecane, as a transfer material. This material can be easily spin coated on graphene and assist the transfer, leaving no residues and requiring no further removal processes. The effectiveness of this transfer method for few-layer graphene on a large area was evaluated and confirmed by microscopy, Raman spectroscopy, x-ray photoemission spectroscopy, and four-point probe measurements. Schottky-barrier solar cells with few-layer graphene were fabricated on silicon wafers by using the cyclododecane transfer method and outperformed reference cells made by standard methods.

    Developing carbon materials featuring both high accessible surface area and high structure stability are desirable to boost the performance of constructed electrochemical electrodes and devices. Herein, we report a new type of microporous carbon (MPC) derived from biomass waste based on a simple high-temperature chemical activation procedure. The optimized MPC-900 possesses microporous structure, high surface area, partially graphitic structure, and particularly low impurity content, which are critical features for enhancing carbon-based electrochemical process. The constructed MPC-900 symmetric supercapacitor exhibits high performances in commercial organic electrolyte such as widened voltage window up to 3 V and thereby high energy/power densities (50.95 Wh kg-1 at 0.44 kW kg-1; 25.3 Wh kg-1 at 21.5 kW kg-1). Furthermore, a simple melt infiltration method has been employed to enclose SnO2 nanocrystals onto the carbon matrix of MPC-900 as a high-performance lithium storage material. The obtained SnO2-MPC composite with ultrafine SnO2 nanocrystals delivers high capacities (1115 mAh g-1 at 0.2 A g-1; 402 mAh g-1 at 10 A g-1) and high-rate cycling lifespan of over 2000 cycles. This work not only develops a microporous carbon with high carbon purity and high surface area, but also provides a general platform for combining electrochemically active materials.

  6. Distribution of anthropogenic fill material within the Y-12 plant area, Oak Ridge, Tennessee

    Sutton, G.E. Jr.; Field, S.M.

    1995-10-01

    Widespread groundwater contamination in the vicinity of the Oak Ridge Y-12 Plant has been documented through a variety of monitoring efforts since the late 1970s. Various contaminants, most notably volatile organic compounds (VOCs), have migrated through the subsurface and formed extensive contaminant plumes within the Knox Aquifer/Maynardville Limestone, the primary exit pathway for groundwater transport within the Bear Creek Valley. In 1991, an integrated, comprehensive effort (Upper East Fork Poplar Creek [UEFPC] Phase I monitoring network) was initiated in order to (1) identify contaminant source areas within the industrialized portions of the plant and (2) define contamination migration pathways existing between the source areas and the Knox Aquifer/Maynardville Limestone. Data obtained during previous studies have indicated that extensive zones of fill and buried utility trenches may serve as preferred migration pathways. In addition, portions of UEFPC were rerouted, with several of its tributaries being filled during the initial construction of the plant. These filled surface drainage features are also believed to serve as preferred migration pathways. The identification of preferred contaminant migration pathways within the Y-12 Plant area is essential and required to refine the current Bear Creek Valley groundwater conceptual model and to assist in the selection of technically feasible and cost effective remedial strategies. This report presents the results of an initial investigation of the occurrence of manmade (anthropogenic) fill and its effect upon groundwater movement within the plant area. These interpretations are subject to revision and improvement as further investigation of the effects of the fill upon contaminant migration progresses

    1989-12-01

    Risk management in an urban areas not always an easy task and the selection of appropriate prevention measure is often difficult. Consequences of an accident can be multiple (mortality, destruction, pollution, interruption of supplies, economic losses, traffic difficulties), and preventive measures are difficult to compare. The objective of this report is to present different methods applicable for decision making emphasising the criteria for their intercomparison and their limitations. In any case a more sophisticated analysis is needed for risk management in urban areas. Principals of methods needed for decision making are presented. These methods are based on a single criteria (regular constraint), on a few criteria that can be measured (cost-benefit), or a number of criteria at choice. These rather general methods should be adaptable to be applied for specific domain. For risk management the following adaptation are presented: identifying the limit of maximum individual risk (generalisation of regular constraint); adoption of different values of human life as a function of nature of consequences (generalisation of cost-benefit method), application of risk avoidance factors. These different developments predict versions of tools for decision making which can be applicable to risk management in urban areas [fr

  9. Application of Hard Metal Weld Deposit in the Area of Mixing Organic Materials

    2014-01-01

    Full Text Available Any machine part is subject to degradation processes. Intensive wear occurs either when two bearing surfaces come into contact or when loose particles rub the function surface of a machine part. Soil processing machines are a good example. A similar process of abrasive wear occurs also in mixing machines or lines for material transport, such as worm-conveyors. The experiment part of this paper analyses hard metal weld deposit dedicated for renovation of abrasive stressed surfaces. In order to prolong the service life of a blade disc in a mixing machine Kreis-Biogas-Dissolver, the technology of hard surfacing by an electric arc was used. Tested hard metal electrodes were applied on a steel tape class 11 373. To eliminate mixing with the base material, weld beads were applied in two layers. Firstly, the weld bead was visually analyzed on a binocular microscope. Further, weld bead as well as the base material was analyzed from the metallographic point of view, whose aim was to identify the structure of weld metal and the origin of microcracks in weld bead. Moreover, there was also measured microhardness of weld metal. Abrasive resistance was tested according to the norm ČSN 01 5084, which is an abrasive cloth test. As in the mixing process also erosion wear occurs, there was also processed a test on a Bond device simulating stress of test samples by loose abrasive particles. The abrading agents were formed by broken stones of 8–16 mm in size. Based on the results of the individual tests, the recommendation of usage hard metal electrodes for prolonging service life of machine parts will be made.

    In the 1980s, CRMs were gradually recognized as an integral part of analytical chemistry as effective tools to verify accuracy of methods. Subsequently, new technologies emerged, and these were capable of processing complex materials without compromising matrix integrity and analyte stability over extended periods of storage. The sequence of events can be outlined as follows: (1) improvements in inorganic methods of analysis, where nuclear analytical techniques played a crucial role, (2) identification of RM needs and assays for organic constituents in foods and environmental materials, (3) a clear understanding of the distinction between primary (certified) and secondary (e.g. check samples for proficiency testing) types of RMs, (4) preparing specific RMs (spiked standards) to address matrix related measurement problems, (5) preparation of slurry and composite (freeze dried and frozen) types of RMs, (6) realization of the need for a global vision in dealing with standards as illustrated by the activities of GESREM, (7) concern for traceability of chemical measurements to internationally recognized standards, and (8) recognition of the need for multidisciplinary approaches for preparing certain types of RMs (e.g. microbiological RMs) in response to the regulatory measurement needs of food safety and environmental health criteria

    The objective of the Red HookIBay Ridge project was to evaluate proposed dredged material from these two areas to determine its suitability for unconfined ocean disposal at the Mud Dump Site. Sediment samples were collected from the Red Hook/Bay Ridge project areas. Tests and analyses were conducted. The evaluation of proposed dredged material from the Red Hook/Bay Ridge project areas consisted of bulk sediment chemical analyses, chemical analyses of dredging site water and elutriate, water-column and benthic acute toxicity tests. Twenty-four individual sediment core samples were collected from these two areas and analyzed for grain size, moisture content, and total organic carbon (TOC). Three composite sediment samples, representing Red Hook Channel and the two Bay Ridge Reaches to be dredged, were analyzed for bulk density, specific gravity, metals, chlorinated pesticides, polychlorinated biphenyl (PCB) congeners, polynuclear aromatic hydrocarbons (PAH), and 1,4-dichlorobenzene. Dredging site water and elutriate water, which is prepared from the suspended-particulate phase (SPP) of the three Red Hook Bay Ridge sediment composites, were analyzed for metals, pesticides, and PCBS. Benthic acute toxicity tests were performed. Water-column or SPP toxicity tests were performed. Bioaccumulation tests were also conducted.

    The purposes of the present study were to examine the pressure transmission area and maximum pressure transmission of thermoplastic resin denture base materials under an impact load, and to evaluate the modulus of elasticity and nanohardness of thermoplastic resin denture base. Three injection-molded thermoplastic resin denture base materials [polycarbonate (Basis PC), ethylene propylene (Duraflex), and polyamide (Valplast)] and one conventional heat-polymerized acrylic resin (PMMA, SR Triplex Hot) denture base, all with a mandibular first molar acrylic resin denture tooth set in were evaluated (n=6). Pressure transmission area and maximum pressure transmission of the specimens under an impact load were observed by using pressure-sensitive sheets. The modulus of elasticity and nanohardness of each denture base (n=10) were measured on 15×15×15×3mm 3 specimen by using an ultramicroindentation system. The pressure transmission area, modulus of elasticity, and nanohardness data were statistically analyzed with 1-way ANOVA, followed by Tamhane or Tukey HSD post hoc test (α=.05). The maximum pressure transmission data were statistically analyzed with Kruskal-Wallis H test, followed by Mann-Whitney U test (α=.05). Polymethyl methacrylate showed significantly larger pressure transmission area and higher maximum pressure transmission than the other groups (Pelasticity and nanohardness among the four types of denture bases (Pelasticity and nanohardness of each type of denture base were demonstrated.

  14. Consultancy on 'Knowledge preservation in the area of fast reactor technology'. Working material

    International Nuclear Information System (INIS)

    2002-01-01

    The fast reactor, which can generate electricity and breed additional fissile material for future fuel stocks is a resource that will be needed when economic uranium supplies for the advanced light water reactors or other thermal-spectrum options diminish. Further, the fast-fission fuel cycle in which material is recycled offers the flexibility needed to contribute decisively towards solving the problem of growing spent fuel inventories by greatly reducing the volume of high-level waste that must be disposed of in long-term repositories. This is a waste management option that also should be retained for future generations. The fast reactor has been the subject of research and development programs in a number of countries for upwards of 40 years. Now, despite early sharing and innovative worldwide research and development, ongoing work is confined to China, India, Japan, the Republic of Korea, and Russia. Information generated worldwide will be needed in the future. Presently, it is in danger of being lost even in those countries continuing the work. Some countries have already taken the issue of knowledge preservation seriously: Japan, France, Britain, and Russia, in particular. At worst, valuable contributory information elsewhere will be lost and would have to be regenerated when needed. The IAEA initiative seeks to establish a comprehensive, international inventory of fast reactor data and knowledge, which would be sufficient to form the basis for fast reactor development in 20 to 40 years from now. The Agency is in a good position to provide the framework for knowledge preservation efforts. Under Article III of its Statute, the IAEA is mandated to encourage and assist research on, and development and practical application of atomic energy for peaceful uses throughout the world. Obviously, an important aspect of this mandate is maintaining and increasing the knowledge that is necessary for the technological development. The main objectives of the consultancy

  15. Large-area, long-term monitoring of mineral barrier materials

    Brandelik, A.; Huebner, C.

    1997-01-01

    Clay-type mineral layers are used for bottom and surface barriers in environmental containment, such as landfill designs. Their performance in terms of isolation depends on the water content and its variation with the time. Sensitive long-term areal mapping of the moisture content can detect in time drying or shearing failures that will have a negative impact on the performance of the barrier. Based on the measurement of the dielectric coefficient (not of the unpredictable electric conductivity as proposed by others), we use the combination of two sensors; the cryo-moisture sensor and the cable network sensor in the clay-type mineral layer. The cryo-moisture sensor measures the depth profile of the absolute water content and the change of density on a small area (diameter approx. 0.2 m). It is selfcalibrating and very accurate. The cable network sensor is a net of moisture sensitive radiofrequency cables. It is buried in the barrier layer and determines variations of the water content of approximately 3% (by volume) with a spatial accuracy of approx. 4 meters. We have used the cryo-sensor since 1992 and already started installing the cable network on an area of approx. 2000 m 2 within a waste disposal surface barrier at Karlsruhe. This system is non-destructive and allows long-term monitoring. It is predicted to operate for longer than 20 years. The calculated costs of acquisition, installation and operation are $ 4.-/m 2 in the first year

    Enhanced levels of natural radioactivity in the ground can cause problems with high concentrations of indoor 222 Rn, elevated levels of gamma radiation and natural radioactive elements in drinking water. Of the Nordic countries it is essentially Finland, Norway and Sweden that have problems with enhanced natural radioactivity in the ground and in building materials. Finland and Sweden have among the highest mean 222 Rn concentrations in dwellings in the world, 123 Bq m -3 and 108 Bq m -3 with a corresponding mean annual effective dose of about 2 mSv. In Sweden about 500,000 and in Finland and Norway about 200,000 persons get their drinking water from wells drilled in bedrock. The water from a large number of these wells contain elevated levels of naturally occurring radioactive elements, primarily 222 Rn. The action levels for 222 Rn in dwellings and above-ground workplaces are essentially the same in Finland, Norway and Sweden: 200 Bq m -3 for new buildings and 400 Bq m -3 for existing buildings. For mines and underground excavations, however, there are some differences. The treatment of gamma emitting natural radionuclides in building materials etc. is similar, although there are differences in the degree of control. The action levels for 222 Rn in drinking water differ from 100 Bq l -1 to 500 Bq l -1 . The action level in Finland has the form of an activity index that restricts also other radioactive nuclides. Denmark has not adopted a formal radon policy and has no recommended or legally binding action levels for 222 Rn or any other naturally occurring radionuclides. (author)

    Mechanical exfoliation has been a key enabler of the exploration of the properties of two-dimensional materials, such as graphene, by providing routine access to high-quality material. The original exfoliation method, which remained largely unchanged during the past decade, provides relatively small flakes with moderate yield. Here, we report a modified approach for exfoliating thin monolayer and few-layer flakes from layered crystals. Our method introduces two process steps that enhance and homogenize the adhesion force between the outermost sheet in contact with a substrate: Prior to exfoliation, ambient adsorbates are effectively removed from the substrate by oxygen plasma cleaning, and an additional heat treatment maximizes the uniform contact area at the interface between the source crystal and the substrate. For graphene exfoliation, these simple process steps increased the yield and the area of the transferred flakes by more than 50 times compared to the established exfoliation methods. Raman and AFM characterization shows that the graphene flakes are of similar high quality as those obtained in previous reports. Graphene field-effect devices were fabricated and measured with back-gating and solution top-gating, yielding mobilities of ∼4000 and 12,000 cm(2)/(V s), respectively, and thus demonstrating excellent electrical properties. Experiments with other layered crystals, e.g., a bismuth strontium calcium copper oxide (BSCCO) superconductor, show enhancements in exfoliation yield and flake area similar to those for graphene, suggesting that our modified exfoliation method provides an effective way for producing large area, high-quality flakes of a wide range of 2D materials.

  18. Pen and platen, piezo-electric (Engineering Materials). [Signature verification for access to restricted areas

    Energy Technology Data Exchange (ETDEWEB)

    The set of five drawings defines a writing instrument system that will reliably verify signatures, thus providing a method useful in screening persons seeking entrance to restricted areas or access to computer programs. Using a conventional ballpoint pen refill, the instrument's input derives from signals generated in its writing tip and from pressure exerted by a person writing his name or a code word on the platen (tablet). The basic principle is that accelerations of the writing tip and pressures exerted by the person writing are recorded in three axes. This combination of signals can be processed by a computer and compared with a record in the computer's memory, or a graphic transcription may be compared visually with an earlier record.

  19. 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.

    1996-01-01

    Man-made low-dimensional magnetic systems including surfaces, interfaces and multilayers, have attracted a great amount of attention in the past decade because, as expected, the lowered symmetry and coordination number offer a variety of opportunities for inducing new and exotic phenomena and so hold out the promise of new device applications. Local spin density functional (LSDF) ab initio electronic-structure calculations employing the full-potential -linearized augmented-plane-wave (FLAPW) method have played a key role in the development of this exciting field by not only providing a clearer understanding of the experimental observations but also predicting new systems with desired properties. One of the striking successes of theory in the last decade has been the calculation of hyperfine fields at surfaces and interfaces. Concurrently, several groups have followed the pioneering work of Korecki and Gradmann and have measured hyperfine fields at surfaces and interfaces. In this paper, it is reviewed new features of hyperfine-interaction investigations in man-made materials which are essential because the hyperfine field is not proportional to the magnetization and so interpretations of experiment are totally dependent on theory

    There is no doubt that, thanks to the pioneering studies of the late seventies and the early eighties, a methodology has been made available that allows risk management of hazardous transportation in urban areas. This approach can easily be extended to the management of other similar risks (storages and to some extent natural hazards). The methodology is both technically available and affordable. The insertion within the decision making processes deserves still some efforts. It has be seen that the applications are broad and numerous. They range from route selection to emergency preparedness, with some insights into acceptability considerations. One limit to the use of such studies, aiming to an objective assessment of the risk, is the complexity of the decision problems, where many factors are to be considered, the most subtle being the one linked to acceptability. However, as such studies develop, those factors start to be clarified, and decision makers learn how to use risk indices in this context. So at the present time it can be said that risk analyses are a valuable input into the decision making process in most cases. And, as more experience is acquired the uses are broader. As any technical innovation risk assessment modifies the approaches to the questions it is dealing with. It seems impossible now to treat those kinds of risks as was done ten years ago.

    Concrete which is generally used as filling material for a buried cavity has very high strength but significantly high self-load is considered its disadvantage. If it is used as filling material, the second collapse due to additional load, causing irreversible damage. If light-weighted foam and active feldspar are used to solve this problem, the second collapse can be prevented by reducing of self-load of filling material. In this study, the specimen was produced by mixing light-weighted foam, active feldspar and cement, and changes in the density, unconfined compressive strength and hydraulic conductivity were analyzed. Using the light-weighted foam could enable the adjustment of density of specimen between 0.5 g/cm3 and 1.7 g/cm3, and if the mixing ratio of the light-weighted foam increases, the specimen has more pores and smaller range of cross-sectional area. It is confirmed that it has direct correlation with the density, and if the specimen has more pores, the density of the specimen is lowered. The density of the specimen influences the unconfined compressive strength and the hydraulic conductivity, and it was also confirmed that the unconfined compressive strength could be adjusted between 0.6 MPa and 8 MPa and the hydraulic conductivity could be adjusted between 10-9cm/sec and 10-3cm/sec. These results indicated that we can adjust unconfined compressive strength and hydraulic conductivity of filling materials by changing the mixing amount of lightweight-weighted foam according to the requirements of the field condition.

    The focus of the project was to design and synthesize light element compounds and nanomaterials that will reversibly store molecular hydrogen for hydrogen storage materials. The primary targets investigated during the last year were amine and hydrogen terminated silicon (Si) nanoparticles, Si alloyed with lighter elements (carbon (C) and boron (B)) and boron nanoparticles. The large surface area of nanoparticles should facilitate a favorable weight to volume ratio, while the low molecular weight elements such as B, nitrogen (N), and Si exist in a variety of inexpensive and readily available precursors. Furthermore, small NPs of Si are nontoxic and non-corrosive. Insights gained from these studies will be applied toward the design and synthesis of hydrogen storage materials that meet the DOE 2010 hydrogen storage targets: cost, hydrogen capacity and reversibility. Two primary routes were explored for the production of nanoparticles smaller than 10 nm in diameter. The first was the reduction of the elemental halides to achieve nanomaterials with chloride surface termination that could subsequently be replaced with amine or hydrogen. The second was the reaction of alkali metal Si or Si alloys with ammonium halides to produce hydrogen capped nanomaterials. These materials were characterized via X-ray powder diffraction, TEM, FTIR, TG/DSC, and NMR spectroscopy.

Para tal propósito, se analizaron los fundamentos curriculares económicos, socioculturales, filosóficos y pedagógicos del currículum costarricense, durante el Estado Neoliberal, en relación con la construcción de una ciudadanía neoliberal; obteniendo una caracterización general de la influencia, directa e indirecta, de un proyecto hegemónico cultural-económico y la formación ciudadana y sus implicaciones educativas.Abstract:The current essay, developed as a complement to the formative activities of the Masters in Curricular Planning of the University of Costa Rica, tries to vindicate the role of the Costa Rican educative system -focused on the curricular area- within the formation of a citizen as an answer to neoliberal political and economical interests, making him a subjective and not neutral social and historical product. In order to reach this goal, the economical, sociocultural, philosophical and pedagogical curricular principles of the Costa Rican curriculum design -during the neoliberal state- were analyzed, in relation to the formation of a neoliberal citizenship. This analysis was made, and a general characterization -of direct and indirect influence- of a cultural and economical hegemonic project was obtained, as well as the citizenship formation and its educative implications.

    This report presents work done under a Phase 2 SBIR contract for demonstrating large area detector planes utilizing Quantex electron trapping materials as a film medium for storing high-energy nuclide impingement information. The detector planes utilize energy dissipated by passage of the high-energy nuclides to produce localized populations of electrons stored in traps. Readout of the localized trapped electron populations is effected by scanning the ET plane with near-infrared, which frees the trapped electrons and results in optical emission at visible wavelengths. The effort involved both optimizing fabrication technology for the detector planes and developing a readout system capable of high spatial resolution for displaying the recorded nuclide passage tracks

    Although remarkable success has been achieved to mimic the mechanically excellent structure of nacre in laboratory-scale models, it remains difficult to foresee mainstream applications due to time-consuming sequential depositions or energy-intensive processes. Here, we introduce a surprisingly simple and rapid methodology for large-area, lightweight, and thick nacre-mimetic films and laminates with superior material properties. Nanoclay sheets with soft polymer coatings are used as ideal building blocks with intrinsic hard/soft character. They are forced to rapidly self-assemble into aligned nacre-mimetic films via paper-making, doctor-blading or simple painting, giving rise to strong and thick films with tensile modulus of 45 GPa and strength of 250 MPa, that is, partly exceeding nacre. The concepts are environmentally friendly, energy-efficient, and economic and are ready for scale-up via continuous roll-to-roll processes. Excellent gas barrier properties, optical translucency, and extraordinary shape-persistent fire-resistance are demonstrated. We foresee advanced large-scale biomimetic materials, relevant for lightweight sustainable construction and energy-efficient transportation.

    Carbon nanotubes (CNTs) are a promising replacement for tungsten filaments as electron emitters in conventional x-ray sources, owing to their higher aspect ratio, superior mechanical stability, chemical inertness, and high electrical and thermal conductivities. Conditions for realizing the best emission behavior from CNTs have been formulated over the last few years. In this paper, we report the relatively less-investigated factor, namely, the influence of the nature of substrate material on the growth as well as field emission characteristics of large-area multiwalled CNTs for their practical application in medical x-ray sources. We compare the morphology of CNTs on a variety of substrates such as stainless steel, copper, molybdenum, graphite, few-layer graphene, and carbon nanowalls grown by thermal chemical vapor deposition following a simple drop-coating of catalyst. We find that CNTs grown on stainless steel and graphite show the best combination of emission characteristics under pulsed operation mode. These studies are helpful in selecting the optimum substrate material for field emission applications. Ex situ studies on field emission degradation of CNTs are presented towards the end.

Descriptive study of a retrospective cohort. SITE: Primary health care, Areas II and V of Zaragoza.Participants. Workers in this areas, distributed by: physician, nursing staff, auxiliary, orderly, housekeeping staff, others. Data of: workers, accident, serologic source, worker protection and vaccinal status of hepatitis B. The incidence of accidents was 26 (period 1997-1999). Most proportion of accidents were declared by nursing (78%). The highest occupational incidence was in auxiliary (63 ). In 90,1% of the cases, the accident was needlestick injury. The source was known in 67,7% of cases. The accidents occurred in hands in 96,8% of cases, and only one third of workers carried gloves. Results obtained are similar with previous studies about this event. We must insist on the need to declare these accidents, providing more information and accessibility for the declaration to worker. Moreover, we must insist on the correct application in the health care field of the standard precautions, because almost 50% of accidents are evitable, and to increase hepatitis B vaccination covertures.

    In this work, a human hair-derived high surface area porous carbon material (HHC) was prepared using potassium hydroxide activation. The morphology and textural properties of the HHC structure, along with its adsorption performance for tetracycline (TC) antibiotics, were evaluated. HHC showed a high surface area of 1505.11m 2 /g and 68.34% microporosity. The effects of most important variables, such as initial concentration (25-355mg/L), solution pH (3-13), and temperatures (30-50°C), on the HHC adsorption performance were investigated. Isotherm data analysis revealed the favorable application of the Langmuir model, with maximum TC uptakes of 128.52, 162.62, and 210.18mg/g at 30, 40, and 50°C, respectively. The experimental data of TC uptakes versus time were analyzed efficiently using a pseudo-first order model. Porous HHC could be an efficient adsorbent for eliminating antibiotic pollutants in wastewater. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available The present study was realized in a Greek 6th grade State Primary School class and was based on Howard Gardner’s theory of multiple intelligences, which was first introduced in 1983. More particularly, it was explored to what extent the young learners possess multiple intelligences through the use of a specially-designed questionnaire and a series of interviews. The findings of the above have served as a tool to the construction of a project work based on students’ learning preferences within a cross-curricular framework, easily applicable to the Greek State School curriculum. All learners were activated to participate within a school environment that traditionally promotes linguistic and mathematical skills matching dominant multiple intelligences or a combination of some of them to thematic units already taught by Greek teachers. The suggested project was assessed through observation and student portfolio, showing that the young learners’ multiple intelligences were exploited to a great extent, promoting the learning process satisfactorily. The results of this study can provide a contribution to the literature of multiple intelligences in the Greek reality and suggest a need for further consideration and exploration in the field. Finally, the researcher of this study hopes the present work could function as a springboard for more elaborated studies in the future.

  14. Damage Simulation in Composite Materials: Why It Matters and What Is Happening Currently at NASA in This Area

    Use of lightweight composite materials in space and aircraft structure designs is often challenging due to high costs associated with structural certification. Of primary concern in the use of composite structures is durability and damage tolerance. This concern is due to the inherent susceptibility of composite materials to both fabrication and service induced flaws. Due to a lack of general industry accepted analysis tools applicable to composites damage simulation, a certification procedure relies almost entirely on testing. It is this reliance on testing, especially compared to structures comprised of legacy metallic materials where damage simulation tools are available, that can drive costs for using composite materials in aerospace structures. The observation that use of composites can be expensive due to testing requirements is not new and as such, research on analysis tools for simulating damage in composite structures has been occurring for several decades. A convenient approach many researchers/model-developers in this area have taken is to select a specific problem relevant to aerospace structural certification and develop a model that is accurate within that scope. Some examples are open hole tension tests, compression after impact tests, low-velocity impact, damage tolerance of an embedded flaw, and fatigue crack growth to name a few. Based on the premise that running analyses is cheaper than running tests, one motivation that many researchers in this area have is that if generally applicable and reliable damage simulation tools were available the dependence on certification testing could be lessened thereby reducing overall design cost. It is generally accepted that simulation tools if applied in this manner would still need to be thoroughly validated and that composite testing will never be completely replaced by analysis. Research and development is currently occurring at NASA to create numerical damage simulation tools applicable to damage in

    Objectives To assess the impact of a program to integrate introductory pharmacy practice experiences with pharmaceutical science topics by promoting active learning, self-directed learning skills, and critical-thinking skills. Design The Learning Bridge, a curriculum program, was created to better integrate the material first-year (P1) students learned in pharmaceutical science courses into their introductory pharmacy practice experiences. Four Learning Bridge assignments required students to interact with their preceptors and answer questions relating to the pharmaceutical science material concurrently covered in their didactic courses. Assessment Surveys of students and preceptors were conducted to measure the effectiveness of the Learning Bridge process. Feedback indicated the Learning Bridge promoted students' interaction with their preceptors as well as development of active learning, self-directed learning, and critical-thinking skills. Students also indicated that the Learning Bridge assignments increased their learning, knowledge of drug information, and comprehension of relevant data in package inserts. Conclusion The Learning Bridge process integrated the didactic and experiential components of the curriculum, enhancing student learning in both areas, and offered students educational opportunities to interact more with their preceptors.

    Full Text Available Partindo da premissa de que a dimensão prática deve ser considerada na formação inicial de professores, entendemos que o Estágio Curricular, se bem fundamentado, estruturado e orientado, configura-se como um momento relevante na perspectiva curricular do processo de formação prática dos futuros professores. Dessa forma, o presente artigo apresenta algumas reflexões e discussões, oriundas de uma investigação qualitativa, sobre a importância e o papel do Estágio Curricular na formação prática de alunos. Os sujeitos desta pesquisa são alunos concluintes do Curso Normal Superior da Universidade do Vale do Paraíba (UNIVAP. A partir da interpretação de diferentes autores(LIMA, 2001; TARDIF, 2002; PIMENTA, 2001; GÓMEZ, 2000, compreendemos a prática enquanto práxis, uma vez que, permeada por um processo de reflexão, ela pode ser construída e reconstruída, objetivando a transformação da realidade escolar. Sendo assim, evidenciamos, nos relatórios apresentados e nos discursos dos alunos, as aprendizagens práticas consideradas construídas durante o estágio. Analisamos os dados recolhidos, à luz da teoria estudada sobre a formação prática e profissional dos professores. Identificamos os aspectos favoráveis e desfavoráveis da realização do estágio curricular na dimensão de ser um espaço/tempo, também destinado à construção de conhecimentos práticos na formação dos professores. E, finalmente, propomos novas perspectivas para a orientação e realização do estágio curricular na formação de professores, centradas na relevância da formação prática e na articulação entre todas as disciplinas do curso de formação.Based on the premise that the practical dimension must be considered in the initial training of teachers, we understand that curricular training, if well founded, structured and oriented, is relevant to the curricular outlook of the practical training process for future teachers.

    The present work is the first systematic and large scale study on radioactive materials and heavy metals in surface soil around the Bayanwula prospective uranium mining area in China. In this work, both natural and anthropogenic radionuclides and heavy metals in 48 surface soil samples were analyzed using High Purity Germanium (HPGe) γ spectrometry and inductively coupled plasma-mass spectrometry (ICP-MS). The obtained mean activity concentrations of 238 U, 226 Ra, 232 Th, 40 K, and 137 Cs were 25.81 ± 9.58, 24.85 ± 2.77, 29.40 ± 3.14, 923.0 ± 47.2, and 5.64 ± 4.56 Bq/kg, respectively. The estimated average absorbed dose rate and annual effective dose rate were 76.7 ± 3.1 nGy/h and 83.1 ± 3.8 μ Sv, respectively. The radium equivalent activity, external hazard index, and internal hazard index were also calculated, and their mean values were within the acceptable limits. The estimated lifetime cancer risk was 3.2 × 10 -4 /Sv. The heavy metal contents of Cr, Ni, Cu, Zn, As, Cd, and Pb from the surface soil samples were measured and their health risks were then assessed. The concentrations of all heavy metals were much lower than the average backgrounds in China except for lead which was about three times higher than that of China's mean. The non-cancer and cancer risks from the heavy metals were estimated, which are all within the acceptable ranges. In addition, the correlations between the radionuclides and the heavy metals in surface soil samples were determined by the Pearson linear coefficient. Strong positive correlations between radionuclides and the heavy metals at the 0.01 significance level were found. In conclusion, the contents of radionuclides and heavy metals in surface soil around the Bayanwula prospective uranium mining area are at a normal level.

  19. Seeing The "New Forest": A Visual Curricular Experiment

    In contemporary Western contexts, human interaction with and interpretation of nature is a perpetually mediated process. Understandings and engagements with natural environments are informed by and often overlaid with meanings derived from representations. In other words, representations help constitute human relationships with nature. Thus learning how representations shape human understandings and experiences of nature and the resulting social, political, and ecological impact of these mediated relationships has emerged as an important field of inquiry within environmental education. This dissertation examines how a critical, self-reflexive act of looking at photographs can challenge an individual's concepts of nature/culture, real/imaginary, and self/other. The project engages in a curricular experiment where the researcher explores how photography meditates her abstract and embodied understandings of specific natural environments. A critical, self-reflexive approach to aesthetic engagement with photographs moves beyond simply deciphering or decoding representations; it incorporates the learner's own narrative and embodied responses to the photographic representations being explored. This approach also recognizes that pedagogy has a transformative effect; both the learner and the representations being explored are transformed through the process of engagement. In this dissertation, a selection of iconic photographs of Canadian tree planting from the collection of the National Gallery of Canada are looked at: Lorraine Gilbert's (1987-2004) series "Shaping the New Forest" and Sarah Anne Johnson's (2005) work "The Tree Planting Project." The aim of this project is twofold: to unravel how these photographs construct and transform knowledge of and relationships with the environment in Canada, and to demonstrate a model of environmental inquiry that can be integrated into critical environmental education curricula.

    Radon exhalation rates from building materials used in high background radiation areas (HBRA) of Ramsar were measured using an active radon gas analyzer with an emanation container. Radon exhalation rates from these samples varied from below the lower detection limit up to 384 Bq.m −2 h −1 . The 226 Ra, 232 Th and 40 K contents were also measured using a high resolution HPGe gamma- ray spectrometer system. The activity concentration of 226 Ra, 232 Th and 40 K content varied from below the minimum detection limit up to 86,400 Bq kg −1 , 187 Bq kg −1 and 1350 Bq kg −1 , respectively. The linear correlation coefficient between radon exhalation rate and radium concentration was 0.90. The result of this survey shows that radon exhalation rate and radium content in some local stones used as basements are extremely high and these samples are main sources of indoor radon emanation as well as external gamma radiation from uranium series. -- Highlights: ► In the selection process of local samples, portable scintillometer (NaI) was used. ► The activity concentration of 226 Ra varied from below the MDL up to 86400 Bq kg −1 . ► The activity concentration of 232 Th varied from below the MDL up to 187 Bq kg −1 . ► The activity concentration of 40 K varied from below the MDL up to 1350 Bq kg −1

    and on achieving the training of a physician capable of answering to social, local and global needs. The implementation of Problem Based Learning is analyzed as well as other didactic strategies, the role of the tutor and internal debate on competences. The study plan was organized around problematic areas, while the previous plan was structured starting from disciplines. The program included new areas of knowledge, among them medical information technology, analysis of human sexuality, communication and phases of the vital cycle not previously contemplated, such as adolescence and old age. Disciplines oriented to health and society were posed in a longitudinal manner and health promotion, disease prevention and attention, and rehabilitation were considered as transcurricular axes. However, a fragmentary mentality that separates disciplines continues to predominate, there is a need to increase practice areas outside the hospital environment, evaluation remains as one of the critical aspects and administrative adjustment is pending. Curricular management should be permanent with ample participation of both faculty and students.

    Objective. To illustrate a method for integrating co-curricular activities, quantify co-curricular activities, and evaluate student perception of achievement of goals. Methods. Throughout a longitudinal course, students engaged in self-selected, co-curricular activities in three categories: professional service, leadership, and community engagement. Hours were documented online with minimum course requirements. Students reflected on experiences and assessed goal attainment. Assignments were reviewed by faculty and feedback was given to each student. Results. From 2010 to 2016, there were 29,341 co-curricular hours documented by 756 students. The most popular events were attending pharmacy organization meetings and participating in immunization clinics. More than half of the students agreed they were able to meet all of their professional goals (mix of career and course goals) while 70% indicated goals were challenging to meet. Conclusion. This method for integrating co-curricular activities using a continuing professional development model demonstrates a sustainable system for promoting professional development through experience and self-reflection.

The present paper is concerned with the bio leaching of U and Cu using Aspergillus Niger (A. Niger) followed their proper recovery. The working Abu Thor representative sample assays 0.22% U as the element of interest as well as up to 25% CuO beside the other rock constituents SiO 2 (33%), Al 2 O 3 (10.4%) and CaO(8.5%). The effective bio leaching of U and Cu from Abu Thor ore sample using A.Niger was performed at the following optimum conditions: an incubation time of 6 days, sample/ liquid (S/L) ratio of 1/10, ph value of 1 and a temperature of 60 degree C. The prepared bio leach liquor assays 0.19 g/l of U and 15.8 g/l of Cu with leaching efficiencies of 97% and 79%, respectively. Uranium was recovered using 25% TBP in kerosene at O/A ratio of 1/1 and contact time of 5 min with achieved extraction efficiency of 96%. However the stripping of U was conducted by using 8% Na 2 CO 3 at A/O ratio of 1/1 and contact time of 5 min with stripping efficiency reached 99%. On the other hand, Cu was directly precipitated as CuS using the freshly released H 2 S gas with the addition of solid Na 2 S. The optimum precipitation conditions were S/L ratio of 1/100, ph 1.5 and room temperature where the precipitation efficiency of Cu achieved 99%

    Full Text Available One of the most important values while forming gear wheels is a material section area Sс which is to be removed by a tool in the process of forming a space between two teeth in one pass. Cutting resistance which is proportional  to section area of  the layer to be cut and, correspondingly, a thermodynamic intensity in the polishing zone depend on Sс value.The paper proposes relations for calculation of a material section area Sс which is to be removed from a blank while forming a space between two teeth of a satellite gear of a planetary pin tooth reducer.Measurements being made in the AutoCAD packet have shown that any corrections of the profile do not make a significant influence on a section area Sс.

    The goal of disposing of low-level radioactive and hazardous waste in shallow landfills is to reduce risk to human health and the environment by isolating contaminants until they no longer pose an unacceptable hazard. In order to achieve this, the Department of Energy Environmental Restoration Program is comparing the performance of several different surface covers at Material Disposal Area (MDA) B in Los Alamos. Two conventional landfill were compared with an improved cover designed to minimize plant and animal intrusion and to minimize water infiltration into the underlying wastes. The conventional covers varied in depth and both conventional and improved designs had different combinations of vegetation (grass verses shrub) and gravel mulch (no mulch verses mulch). These treatments were applied to each of 12 plots and water balance parameters were measured from March1987 through June 1995. Adding a gravel mulch significantly influenced the plant covered field plots receiving no gravel mulch averaged 21.2% shrub cover, while plots with gravel had a 20% larger percent cover of shrubs. However, the influence of gravel mulch on the grass cover was even larger than the influence on shrub cover, average grass cover on the plots with no gravel was 16.3%, compared with a 42% increase in grass cover due to gravel mulch. These cover relationships are important to reduce runoff on the landfill cover, as shown by a regression model that predicts that as ground cover is increased from 30 to 90%,annual runoff is reduced from 8.8 to 0.98 cm-a nine-fold increase. We also found that decreasing the slope of the landfill cover from 6 to 2% reduced runoff from the landfill cover by 2.7-fold. To minimize the risk of hazardous waste from landfills to humans, runoff and seepage need to be minimized and evapotranspiration maximized on the landfill cover. This has to be accomplished for dry and wet years at MDA B. Seepage consisted of 1.9% and 6.2% of the precipitation in the average and

    From 1982 through 1987, Los Alamos National Laboratory (LANL) performed surety laboratory operations for the U.S. Army Medical Research and Development Command (MRDC). Room 4009 in building SM-29, TA-3, was used as the laboratory for work with the following chemical surety material (CSM) agents: sarin (GB), soman (GD), lewisite (L), and distilled mustard (HD) radio-labelled with H 3 or C 14 . The work was confined to three CSM-certified fume hoods, located in room 4009 (see diagram in Appendix C). The laboratory ceased all active operations during the late 1986 and early 1987 period. From 1987 until 1993 the laboratory was secured and the ventilation system continued to operate. During late 1992, the decision was made to utilize this laboratory space for other operations, thus a decision was made to dismantle and reconfigure this room. LANL sub-contracted Battelle Memorial Institute (BMI) to draw upon the CSM experience of the technical staff from the Hazardous Materials Research Facility (HMRF) to assist in developing a decontamination and decommissioning plan. BMI was subcontracted to devise a CSM safety training course, and a sampling and air monitoring plan for CSM material to ensure personnel safety during all disassembly operations. LANL subcontracted Johnson Controls personnel to perform all disassembly operations. Beginning in early 1993 BMI personnel from the HMRF visited the laboratory to develop both the safety plan and the sample and air monitoring plan. Execution of that plan began in September 1993 and was completed in January 1994

    1983-01-01

    Liquid diffusion masks and liquid dopants to replace the more expensive CVD SiO2 mask and gaseous diffusion processes were investigated. Silicon pellets were prepared in the silicon shot tower; and solar cells were fabricated using web grown where the pellets were used as a replenishment material. Verification runs were made using the boron dopant and liquid diffusion mask materials. The average of cells produced in these runs was 13%. The relationship of sheet resistivity, temperature, gas flows, and gas composition for the diffusion of the P-8 liquid phosphorus solution was investigated. Solar cells processed from web grown from Si shot material were evaluated, and results qualified the use of the material produced in the shot tower for web furnace feed stock.

    2016-01-01

    Full Text Available This article presents the administration of the curricular reorientation that occurred in the municipal district of Dourados-MS in the period 2001 to 2008, trying to describe the official proposal of the process of curricular reorientation and to identify the barriers and facilitators in the materialization of the management. The investigation was developed in a qualitative perspective through observation, bibliographical research, a documental corpus and interview with directors, coordinators and teachers of four schools that lived the process. The results evidenced that there was not an effective participation in the moments of conception nor in the definition of the implementation strategies and/ or evaluation of the proposal. In respect to the development and/or reinforcement of the autonomy through the administration, this was compromised, because there was not wide consultation on the implanted methodological alternative. The power relationships inside and outside school stayed unaffected. The results confirm the complexity in the materialization of the democratic administration in the context of the municipal public administration.

  11. Topic Order in Introductory Physics and its Impact on the STEM Curricular Ladder

    Directory of Open Access Journals (Sweden)

    Teresa L Larkin

    2017-02-01

    Full Text Available Introductory physics courses are an important rung on the curricular ladder in STEM. These courses help to strengthen students critical thinking and problem solving skills while simultaneously introducing them to many topics they will explore in more detail in later courses in physics and engineering. For these reasons, introductory physics is a required element on the curricular ladder. Most often, introductory physics is offered as a two-semester sequence with basic mechanics being taught in the first semester and electricity and magnetism in the second. In fact, this curricular sequence has not been altered in decades. Is there a reason for this? There are many other enduring questions that arise pertaining to these foundation courses in physics. These questions include: Does taking the introductory course sequence “out of order” have an impact on student learning in physics? What topics should be taught? When should these topics be taught? What topics could be left out? The list of questions is essentially endless. This paper will address some of these questions in part, through a brief discussion on student learning in a second-semester algebra-based physics course. Connections will also be made to the broader curricular ladder in STEM. To this end, an illustration that makes connections to an engineering statics course will be presented. This discussion will conclude by presenting some broader implications for the larger STEM communities.

    Energy Technology Data Exchange (ETDEWEB)

    Moore, T.E.; Smith, J.M.

    1994-04-01

    From 1982 through 1987, Los Alamos National Laboratory (LANL) performed surety laboratory operations for the U.S. Army Medical Research and Development Command (MRDC). Room 4009 in building SM-29, TA-3, was used as the laboratory for work with the following chemical surety material (CSM) agents: sarin (GB), soman (GD), lewisite (L), and distilled mustard (HD) radio-labelled with H{sup 3} or C{sup 14}. The work was confined to three CSM-certified fume hoods, located in room 4009 (see diagram in Appendix C). The laboratory ceased all active operations during the late 1986 and early 1987 period. From 1987 until 1993 the laboratory was secured and the ventilation system continued to operate. During late 1992, the decision was made to utilize this laboratory space for other operations, thus a decision was made to dismantle and reconfigure this room. LANL sub-contracted Battelle Memorial Institute (BMI) to draw upon the CSM experience of the technical staff from the Hazardous Materials Research Facility (HMRF) to assist in developing a decontamination and decommissioning plan. BMI was subcontracted to devise a CSM safety training course, and a sampling and air monitoring plan for CSM material to ensure personnel safety during all disassembly operations. LANL subcontracted Johnson Controls personnel to perform all disassembly operations. Beginning in early 1993 BMI personnel from the HMRF visited the laboratory to develop both the safety plan and the sample and air monitoring plan. Execution of that plan began in September 1993 and was completed in January 1994.

Así muestra como en Chile, a pesar de partir de una política educativa en la que no había entrado la idea de currículum, ésta empieza a emerger conforme se va construyendo su desarrollo práctico y curricular. De todas las lecciones aprendidas en el proceso destaca que son componentes clave del proceso la participación y la innovación. Argumenta que hay razones sustantivas y políticas para ello. La primera es clave para que el profesorado se apropie de la propuesta de reforma y la haga posible. Por último, destaca que se produce un desarrollo de las capacidades institucionales de diseño y desarrollo curricular en la medida que se ponen en marcha y acumulan procesos de este tipo.

  2. The Ndop plain clayey materials (Bamenda area – NW Cameroon: Mineralogical, geochemical, physical characteristics and properties of their fired products

    Directory of Open Access Journals (Sweden)

    Rose Yongue-Fouateu

    2016-09-01

    Full Text Available The physicochemical, mineralogical and technological properties of clayey materials from the Ndop plain (NW Cameroon have been investigated, for their ceramic applications. The clayey materials have mixed facies with colour ranging from brown, grey, mottled and yellowish brown. The thickness of the exploitable clay layer is more than 5 m. Their mineralogical constituents are quartz, kaolinite, illite and feldspars, with kaolinite as major clay mineral. Based on the geochemistry, their source rocks might be felsic, with a mafic rock inference. These materials display high percentage in fine particles and high Atterberg limits. For all the firing temperatures, flexural strength (1.2–11 MPa, water absorption (8.03–24.27%, linear shrinkage (2.10%, weight loss (4.88–16.54% and bulk density (1.57–2.03 g/cm3 indicate good ceramic properties for firing samples between 900 and 1100 °C. Most of the fired test bricks show a brick red colour with good to very good cohesion. The studied clays were thus, suitable as raw materials for roof tiles, light weight blocks and hollow bricks; however, mixing of high clayey and highly silty materials could improve the quality of the products.

  3. Atomic structure from large-area, low-dose exposures of materials: A new route to circumvent radiation damage

    Energy Technology Data Exchange (ETDEWEB)

    Meyer, J.C., E-mail: jannik.meyer@univie.ac.at; Kotakoski, J.; Mangler, C.

    2014-10-15

    Beam-induced structural modifications are a major nuisance in the study of materials by high-resolution electron microscopy. Here, we introduce a new approach to circumvent the radiation damage problem by a statistical treatment of large, noisy, low-dose data sets of non-periodic configurations (e.g. defects) in the material. We distribute the dose over a mixture of different defect structures at random positions and with random orientations, and recover representative model images via a maximum likelihood search. We demonstrate reconstructions from simulated images at such low doses that the location of individual entities is not possible. The approach may open a route to study currently inaccessible beam-sensitive configurations. - Highlights: • A new approach to circumvent radiation damage. • Statistical treatment of large noisy data sets. • Analysis of radiation sensitive material defects.

    Schmeck, J; Schmeck, S B; Kohnen, W; Werner, C; Schäfer, M; Gervais, H

    2008-08-01

    The implementation of diagnosis-related groups (DRGs) sharply increased economic pressure on hospitals. Hence, process optimization was focussed on cost-intensive areas, namely the operation room (OR) departments. Work-flow in the OR is characterized by a mandatory interlocking of the job functions of many different occupational groups and the availability of a variety of different materials. Alternatives for staff assignment optimization have been published in numerous publications dealing with the importance of OR management. In this connection the issue of material logistics in the context of OR management has not been frequently addressed. In order to perform a surgical procedure according to plan, one depends on personnel and on timely availability of the materials needed. Supply of sterilized materials is of utmost importance, because in most hospitals sterilized surgical devices constitute a critical resource. In order to coordinate the OR process with the production flow of sterilized materials, an organizational connection to the OR management makes sense. Hence, in a German university hospital the Department of Hospital Sterile Supplies was integrated into the OR management of the Department of Anesthesiology. This led to a close coordination of work-flow processes, and concomitantly a significant reduction of production costs of sterile supplies could be achieved by direct interaction with the OR. Thus, hospital sterile supplies can reasonably be integrated into an OR management representing a new interesting business area for OR organization.

  10. Protective Behaviour of Citizens to Transport Accidents Involving Hazardous Materials: A Discrete Choice Experiment Applied to Populated Areas nearby Waterways.

    Directory of Open Access Journals (Sweden)

    Esther W de Bekker-Grob

    Full Text Available To improve the information for and preparation of citizens at risk to hazardous material transport accidents, a first important step is to determine how different characteristics of hazardous material transport accidents will influence citizens' protective behaviour. However, quantitative studies investigating citizens' protective behaviour in case of hazardous material transport accidents are scarce.A discrete choice experiment was conducted among subjects (19-64 years living in the direct vicinity of a large waterway. Scenarios were described by three transport accident characteristics: odour perception, smoke/vapour perception, and the proportion of people in the environment that were leaving at their own discretion. Subjects were asked to consider each scenario as realistic and to choose the alternative that was most appealing to them: staying, seeking shelter, or escaping. A panel error component model was used to quantify how different transport accident characteristics influenced subjects' protective behaviour.The response was 44% (881/1,994. The predicted probability that a subject would stay ranged from 1% in case of a severe looking accident till 62% in case of a mild looking accident. All three transport accident characteristics proved to influence protective behaviour. Particularly a perception of strong ammonia or mercaptan odours and visible smoke/vapour close to citizens had the strongest positive influence on escaping. In general, 'escaping' was more preferred than 'seeking shelter', although stated preference heterogeneity among subjects for these protective behaviour options was substantial. Males were less willing to seek shelter than females, whereas elderly people were more willing to escape than younger people.Various characteristics of transport accident involving hazardous materials influence subjects' protective behaviour. The preference heterogeneity shows that information needs to be targeted differently depending on

Destaca as dificuldades vividas pelo corpo docente da escola e desenvolve o argumento de que propostas curriculares inovadoras podem criar um espaço discursivo no qual se segregam as crianças das camadas populares, reduzindo suas possibilidades de autonomia na sociedade. Com base nas concepções de política de Stephen Ball e Jenny Ozga, analisam-se os textos políticos da Escola Plural e de uma escola da rede municipal. Verificou-se a complexa relação entre documentos oficiais e experiências locais, bem como a necessidade de se afirmar a importância do conhecimento escolar no currículo. Argumenta-se que a supervalorização do aluno e de suas experiências culturais, em associação com a secundarização do conhecimento escolar, pode criar um espaço em que a criança seja confinada e jamais vista como normal.The paper focuses on a process of curriculum construction which was developed in a school from the Belo Horizonte educational system.

    2016-04-01

    Full Text Available Lack of preparation in science leads to high rates of attrition among science, technology, engineering, and mathematics (STEM majors, even among students who are highly oriented toward STEM. Using data for twenty-seven countries from the 2006 Program for International Student Assessment, we compare the United States with other industrialized countries in terms of fifteen-year-olds’ science achievement and their expectations to focus on STEM in the future. The United States trails most countries in the mean science achievement of the general student population and among students expecting to pursue STEM majors or careers. Lack of curricular standardization in the United States is related to this lower science achievement. Countries with higher curricular standardization exhibit higher average science achievement scores; science achievement and students’ future orientation toward science are also better aligned in these countries. We discuss the implications of these findings for American colleges and universities as they seek to reduce student attrition in STEM fields.

  20. Awareness, Analysis, and Action: Curricular Alignment for Student Success in General Chemistry

    Science.gov (United States)

    2018-01-01

    This article examines the ways that a shared faculty experience across five partner institutions led to a deep awareness of the curriculum and pedagogy of general chemistry coursework, and ultimately, to a collaborative action plan for student success. The team identified key differences and similarities in course content and instructional experiences. The comparative analysis yielded many more similarities than differences, and therefore, the team shifted its focus from “gap analysis” to an exploration of common curricular challenges. To address these challenges, the team developed content for targeted instructional resources that promoted the success of all STEM students across institutions. This article contextualizes the interinstitutional collaboration and closely examines the interactive components (awareness, analysis, and action), critical tools, and productive attitudes that undergirded the curricular alignment process of the STEM Transfer Student Success Initiative (t-STEM).

  3. Variation in chlorophyll content per unit leaf area in spring wheat and implications for selection in segregating material.

    Directory of Open Access Journals (Sweden)

    John Hamblin

    Full Text Available Reduced levels of leaf chlorophyll content per unit leaf area in crops may be of advantage in the search for higher yields. Possible reasons include better light distribution in the crop canopy and less photochemical damage to leaves absorbing more light energy than required for maximum photosynthesis. Reduced chlorophyll may also reduce the heat load at the top of canopy, reducing water requirements to cool leaves. Chloroplasts are nutrient rich and reducing their number may increase available nutrients for growth and development. To determine whether this hypothesis has any validity in spring wheat requires an understanding of genotypic differences in leaf chlorophyll content per unit area in diverse germplasm. This was measured with a SPAD 502 as SPAD units. The study was conducted in series of environments involving up to 28 genotypes, mainly spring wheat. In general, substantial and repeatable genotypic variation was observed. Consistent SPAD readings were recorded for different sampling positions on leaves, between different leaves on single plant, between different plants of the same genotype, and between different genotypes grown in the same or different environments. Plant nutrition affected SPAD units in nutrient poor environments. Wheat genotypes DBW 10 and Transfer were identified as having consistent and contrasting high and low average SPAD readings of 52 and 32 units, respectively, and a methodology to allow selection in segregating populations has been developed.

    1981-01-01

    Liquid diffusion masks and liquid applied dopants to replace the CVD Silox masking and gaseous diffusion operations specified for forming junctions in the Westinghouse baseline process sequence for producing solar cells from dendritic web silicon were investigated. The baseline diffusion masking and drive processes were compared with those involving direct liquid applications to the dendritic web silicon strips. Attempts were made to control the number of variables by subjecting dendritic web strips cut from a single web crystal to both types of operations. Data generated reinforced earlier conclusions that efficiency levels at least as high as those achieved with the baseline back junction formation process can be achieved using liquid diffusion masks and liquid dopants. The deliveries of dendritic web sheet material and solar cells specified by the current contract were made as scheduled.

    In order to analyze the local minute strain in semiconductor materials and devices, we have demonstrated formation of X-ray microbeams by using asymmetric Bragg reflections of the crystal and a zone plate or cylindrical mirror combined with synchrotron radiation. A series of X-ray rocking curves have been obtained by scanning the sample with using the X-ray microbeam. In addition, reciprocal space maps have also been obtained by inserting an analyzer crystal behind the sample. From these data, information on the strain distribution can be obtained for various samples, such as the strain near SiO sub 2 /Si film edges, that in silicon-on-insulator (SOI) crystals, and that in InGaAsP semiconductor laser stripes.

    Slavin, Stuart J; Schindler, Debra L; Chibnall, John T

    2014-04-01

    Medical education can have significant negative effects on the well-being of medical students. To date, efforts to improve student mental health have focused largely on improving access to mental health providers, reducing the stigma and other barriers to mental health treatment, and implementing ancillary wellness programs. Still, new and innovative models that build on these efforts by directly addressing the root causes of stress that lie within the curriculum itself are needed to properly promote student wellness. In this article, the authors present a new paradigm for improving medical student mental health, by describing an integrated, multifaceted, preclinical curricular change program implemented through the Office of Curricular Affairs at the Saint Louis University School of Medicine starting in the 2009-2010 academic year. The authors found that significant but efficient changes to course content, contact hours, scheduling, grading, electives, learning communities, and required resilience/mindfulness experiences were associated with significantly lower levels of depression symptoms, anxiety symptoms, and stress, and significantly higher levels of community cohesion, in medical students who participated in the expanded wellness program compared with those who preceded its implementation. The authors discuss the utility and relevance of such curricular changes as an overlooked component of change models for improving medical student mental health.

    Full Text Available This work has its origins in a survey conducted during the supervised curricular stage of Biological Sciences course at Federal University of Goiás. The article describes critically and analytically every step of the curricular stage, especially the classes with the themes: reproduction and sexuality. The classes were taught to elementary students in State College St. Bernadete in Goiânia-GO. To facilitate the process of teaching and learning the trainees divided the themes into subtopics, and several teaching resources were developed for each subtopic. The research was descriptive and exploratory, using interviews with school students, teachers, supervisors and college students to collect data that allowed assessing the success of the teaching methodologies applied by the teachers in training. The field diaries of the trainees were also used to compose the analysis. Through the statements of the participants, it is considered that the methods achieved their goal in clarifying the issues. The resources used not only brought understanding, but encouraged the participation of the students. The article has been organized according to the steps of the curricular stage and it exposes all the impressions of the supervising teachers, school students and undergraduates during the internship, highlighting, comments, concerns, planning and execution process of the activities.

    After successive Liaison Committee on Medical Education accreditation reports that criticized the University of California, San Francisco, School of Medicine for lack of instructional innovation and curriculum oversight, the dean issued a mandate for curriculum reform in 1997. Could a medical school that prided itself on innovation in research and health care do the same in education? The authors describe their five-phase curriculum change process and correlate this to an eight-step leadership model. The first phase of curricular change is to establish a compelling need for change; it requires leaders to create a sense of urgency and build a guiding coalition to achieve action. The second phase of curriculum reform is to envision a bold new curriculum; leaders must develop such a vision and communicate it broadly. The third phase is to design curriculum and obtain the necessary approvals; this requires leaders to empower broad-based action and generate short-term wins. In the fourth phase, specific courses are developed for the new curriculum, and leaders continue to empower broad-based action, generate short-term wins, consolidate gains, and produce more change. During the fifth phase of implementation and evaluation, leaders need to further consolidate gains, produce more change, and anchor new approaches in the institution. Arising from this experience and the correlation of curricular change phases with leadership steps, the authors identify 27 specific leadership strategies they employed in their curricular reform process.

    Full Text Available In this paper we addressed aspects of the disciplines “Curricular Training” and “Didactics” in the Pedagogy Course in training of teachers. The main objective is to emphasize upon submission of the work that we do in our teaching practice in the mentioned disciplines, the importance of linking the theory and the practice in training of teachers so that the teaching in the university it is not decontextualized but enriched with the issues of everyday school life. In this sense, we address, initially, the aspects of the Curricular training as a mediator link of the learning, of the articulation of the curriculum and of the practices and, in this view, as a productive conduit between the university and the basic education, stressing the need for the reception of the contribution that each institutions within its specificity, must provide in the training courses. In sequence, we present aspects of the structure of the work we do with our students in Early Childhood Education Curricular Training. Finally, are detailed the aspects of a Didactics for the teachers of early childhood education and for the early years of Fundamental Education, focusing on narratives of in-service teachers on their experiences teaching in search of new systematization of pedagogical practice and on by own teachers.

    Full Text Available This paper, whose objective is to analyze two curricular proposals of Portuguese from the Juiz de Fora City Hall (2001 and 2012, is an extract from a research entitled “On text genres and teaching: a collaborative research with teachers of Portuguese” (2011/2013. Text genres have been suggested by curricular proposals as a central object for teachers who work with Portuguese language teaching; for this, it is relevant to analyze the documents in the realm of the ongoing research. As theoretical references, we used authors who propose a didactic model based on the development of language skills and linguistic reasoning (MENDONÇA, 2006 which in turn are based on an interactional conception of language (BRONCKART, 1999; SCHNEUWLY; DOLZ, 2004. Document analysis was used as methodology, which envisions assessment of pieces of information in documents as well as their outcomes. The data show that the 2012 curricular proposal is more adequate to Portuguese language teaching than the first one, mainly for its theoretical and methodological grounding, which emphasize the development of students’ linguistic and discursive skills. Guided by an interactionist notion – unlike the norm-centered 2001 proposal – the 2012 document fosters the development of linguistic reasoning and usage skills.

  1. Assessment of temporal trend of radiation dose to the public living in the large area contaminated with radioactive materials after a nuclear power plant accident

    It has been about 5 years since the Fukushima nuclear power plant accident, which contaminated large area with radioactive materials. It is necessary to assess radiation dose to establish evacuation areas and to set decontamination goal for the large contaminated area. In this study, we assessed temporal trend of radiation dose to the public living in the large area contaminated with radioactive materials after the Fukushima nuclear power plant accident. The dose assessment was performed based on Chernobyl model and RESRAD model for two evacuation lift areas, Kawauchi and Naraha. It was reported that deposition densities in the areas were 4.3-96 kBq m{sup -2} for {sup 134}Cs, 1.4-300 kBq m{sup -2} for {sup 137}Cs, respectively. Radiation dose to the residents depended on radioactive cesium concentrations in the soil, ranging 0.11-2.4 mSv y{sup -1} at Kawauchi area and 0.69-1.1 mSv y{sup -1} at Naraha area in July 2014. The difference was less than 5% in radiation doses estimated by two different models. Radiation dose decreased with calendar time and the decreasing slope varied depending on dose assessment models. Based on the Chernobyl dosimetry model, radiation doses decreased with calendar time to about 65% level of the radiation dose in 2014 after 1 year, 11% level after 10 years, and 5.6% level after 30 years. RESRAD dosimetry model more slowly decreased radiation dose with time to about 85% level after 1 year, 40% level after 10 years, and 15% level after 30 years. The decrease of radiation dose can be mainly attributed into radioactive decays and environmental transport of the radioactive cesium. Only environmental transports of radioactive cesium without consideration of radioactive decays decreased radiation dose additionally 43% after 1 year, 72% after 3 years, 80% after 10 years, and 83% after 30 years. Radiation doses estimated with cesium concentration in the soil based on Chernobyl dosimetry model were compared with directly measured radiation doses

    The continuous perfusion with an artificial cerebrospinal fluid of the cervicotrigeminal area of the spinal cord in halothane-anaesthetized rats allowed the collection of calcitonin gene-related peptide-like material with the same immunological and chromatographic characteristics as authentic rat alpha-calcitonin gene-related peptide. The spinal release of calcitonin gene-related peptide-like material could be significantly increased by the local application of 60 mM K+ (approximately +100%), high-intensity percutaneous electrical stimulation (approximately +200%) and noxious heat (by immersion in water at 52 degrees C; approximately +150%) applied to the muzzle. By contrast, noxious mechanical (pinches) and chemical (subcutaneous formalin injection) stimulations and deep cooling (by immersion in water at 0 degrees C) of the muzzle did not alter the spinal release of calcitonin gene-related peptide-like material. In addition, low-intensity electrical stimulation, recruiting only the A alpha/beta primary afferent fibres, significantly reduced (approximately -30%) the release of calcitonin gene-related peptide-like material from the cervicotrigeminal area. These data suggest that among the various types of natural noxious stimuli, noxious heat may selectively excite calcitonin gene-related peptide-containing A delta and C primary afferent fibres projecting within the dorsal horn of the spinal cord, and that activation of A alpha/beta fibres reduces spontaneous calcitonin gene-related peptide-like material release possibly through an inhibitory presynaptic control of calcitonin gene-related peptide-containing A delta/C fibres.

    Herbarium mosses from 1879-1881, 1973-1975 and 2006-2007 were used to investigate the historical changes of atmospheric deposition of polycyclic aromatic hydrocarbons (PAHs) at a remote site in Northern Spain. Natural abundance of nitrogen and carbon isotopes was also measured in order to assess the evolution of emissions from anthropogenic sources. Nitrogen and PAH concentrations as well as δ 13C and δ 15N ratios were significantly higher in 19th century samples compared to present century samples. Moreover, PAH distribution varied over the centuries, with the trend towards enrichment in light PAHs. The carbon, nitrogen and PAH concentrations measured in the mosses tally with the historical evolution of anthropogenic emissions in the area, mainly influenced by changes in economic activities, domestic heating and road traffic density. Mosses provided by herbaria seem to offer the possibility of studying long-term temporal evolution of atmospheric PAH deposition.

    This study examines the personal and curricular resources available to Delaware's elementary teachers during a time of innovative curriculum change, i.e., their knowledge, goals and beliefs regarding elementary engineering curriculum and the pedagogical support to teach two Science and Engineering Practices provided by science teaching materials. Delaware was at the forefront of K-12 STEM movement, first to adopt statewide elementary curriculum materials to complement existing science units, and one of the first to adopt the new science standards--Next Generation Science Standards. What supports were available to teachers as they adapted and adopted this new curriculum? To investigate this question, I examined (1) teachers' beliefs about engineering and the engineering curriculum, and (2) the pedagogical supports available to teachers in selected science and engineering curriculum. Teachers' knowledge, goals, and beliefs regarding Delaware's adoption of new elementary engineering curriculum were surveyed using an adapted version of the Design, Engineering, and Technology Survey (Hong, Purser, & Gardella, 2011; Yaser, Baker, Carpius, Krauss, & Roberts, 2006). Also, three open ended questions sought to reveal deeper understanding of teacher knowledge and understanding of engineering; their concerns about personal and systemic resources related to the new curriculum, its logistics, and feasibility; and their beliefs about the potential positive impact presented by the engineering education initiative. Teacher concerns were analyzed using the Concerns-Based Adoption Model (Hall & Hord, 2010). Lay understandings of engineering were analyzed by contrasting naive representations of engineering with three key characteristics of engineering adapted from an earlier study (Capobianco Diefes-Dux, Mena, & Weller, 2011). Survey findings for teachers who had attended training and those who have not yet attended professional development in the new curriculum were compared with few

    Full Text Available The Urban Heat Island (UHI is a well-known phenomenon concerning an increasing percentage of the world’s population due to the growth rates of metropolitan areas. Given the health and economic implications of UHIs, several mitigation techniques are being evaluated and tested. In this study, we consider the use of highly reflective materials for urban surfaces, and we carried out numerical experiments using the Weather Research and Forecasting model coupled with the CHIMERE model in order to investigate the effects of these materials on the meteorology and air quality in the urban area of Milan (Italy. Results show that an increase in albedo from 0.2 to 0.7 for urban roofs, walls and streets leads to a decrease in UHI intensity by up to 2–3 °C and of the planetary boundary layer (PBL height of about 500 m. However, the difference of PM10 and ozone between urban and surrounding areas increases by a factor of about 2, attributable to the reduction of PBL height and wind speed and to the increased reflected solar radiation that may enhance photochemical production during the daytime. Therefore, if anthropogenic emissions are held at the same levels, the potential benefit to the UHI in terms of thermal discomfort may have negative repercussions on air quality.

    Full Text Available Objectives: In 2008, the Gulf Medical College in the United Arab Emirates underwent a curricular change from a discipline-based to an organ-system-based integrated curriculum. In this context, this study aimed to compare the faculty and students’ perceptions of the student experiences with the new curriculum. Methods: Data were collected from faculty and second-year students in the integrated curriculum using the Dundee Ready Education Environment Measure (DREEM. Data collected were transferred to Predictive Analytics Software, Version 18. Global and domain scores were assessed with the Wilcoxon Rank-Sum Test. Percentage agreement, disagreement and uncertainty were assessed by the z-test for proportion. Results: There were no significant differences between the total DREEM scores of faculty (139/200 and students (135/200. The faculty perceived that the students were experiencing significantly more positive learning as indicated by the domain score of “Students' Perceptions of Learning”. Proportions of agreement between faculty and students showed that more faculty members than students perceived the need for increased feedback to students and a greater emphasis on long term learning. Conclusion: The study showed that the faculty and students had similar perceptions about the student experiences in the integrated curriculum. Areas necessitating remedial measures were the need for faculty to learn constructive feedback techniques and an emphasis on long term learning in the new curriculum.

    In this paper, my aim is to problematize the invisibility (to instructors) of the purposes of particular exercises within research-based instructional materials (RBIMs) and to provide one possible solution to this problem that other teacher educators may adapt for their institutional contexts. In particular, I show that many RBIMs anticipate and respond to particular (often incorrect) learner ideas, that teachers often do not recognize this, and that not recognizing this can cause teachers to miss opportunities to build on learner ideas and/or engage students in scientific practices. I share an instructional activity I designed that is meant to support teachers—including university physics Learning Assistants—in recognizing the purposes of particular questions or sequences of questions within RBIMs, and I illustrate that this activity can be a productive starting place for conversation about RBIMs.

    A technical assessment of the critical issues and problem areas in the field of plasma materials interactions (PMI) in magnetic fusion devices shows these problems to be central for near-term experiments, for intermediate-range reactor devices including D-T burning physics experiments, and for long-term reactor machines. Critical technical issues are ones central to understanding and successful operation of existing and near-term experiments/reactors or devices of great importance for the long run, i.e., ones which will require an extensive, long-term development effort and thus should receive attention now. Four subgroups were formed to assess the critical PMI issues along four major lines: (1) PMI and plasma confinement physics experiments; (2) plasma-edge modelling and theory; (3) surface physics; and (4) materials technology for in-vessel components and the first wall. The report which follows is divided into four major sections, one for each of these topics

    The current rationale, range and significance of Integrated Water Resources Management (IWRM) are subject to increasing dimensionality, such as systemic conflicts between water users, increasing regulatory influences, and the growing energy requirements for providing the appropriate water resources. The competition between urban and agricultural consumers for water is dealt with as are regulatory, technological and socio-economic aspects of IWRM. The conference proceedings of IWRM Karlsruhe 2012 impart knowledge and relate practical experience in three key areas of IWRM: 1. Challenges for Future Cities and Efficient Agricultural Production Satisfying the growing demand for fresh water for a growing population as well as for agriculture bears the risk of aggravating the conflict between economic and ecological needs. Providing a reliable and secure supply of water for our future cities requires appropriate technical infrastructure systems coupled with environmentally optimized management. In this context it is essential to have greater awareness of the relationship of water and energy and of the overall water usage including the re-use of water 2. Competing Water Uses Water must be shared between domestic/municipal, industrial, agricultural, and hydropower users as well as between regions. This competition is intensified by the vulnerability of supply and sanitation systems to increasing climate extremes and to terrorism. 3. Regulatory and Policy Framework Using water is associated with a great number of externalities. For this reason a proper legislative and regulatory framework is prerequisite for proper management of the water supply, sewerage and storm-water services as well as water usage, all of which are essential for public health, economic development and environmental protection.

    A study has been carried out to determine the natural occurring radioactivity and heavy metal at an industrial site area Gebeng, Pahang. Sampling has been done in four different stations. This study has been carried out to determine the natural radioactivity ( 238 U, 232 Th, 40 K and 226 Ra) and heavy metal in soil sample. Natural radioactivities were determined using Gamma Spectrometry System, the heavy metal determination was done using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). The result for analysis radioactivity concentration showed that Uranium-238 were in the range of 28.18 ± 4.78 Bq/ kg - 39.63 ± 4.79 Bq/ kg, while the concentration for Thorium-232 were in the range of 45.66 ± 5.49 Bq/ kg - 72.43 ± 9.47 Bq/ kg and for the Radium-226, the concentration were in the range of 8.93 ± 1.15 Bq/ kg - 14.29 ± 2.61 Bq/ kg. The concentration of Potassium-40 were in the range of 51.06 ± 12.18 Bq/ kg - 426.28 ± 137.70 Bq/ kg. 8 heavy metals have been found from the four different stations which are Al, Fe, V, Mn, Cr, Cu, Zn and Pb. Fe show the highest concentration among the other heavy metal while Pb show the lowest concentration. From this study, the specific activities of natural radionuclide in almost all stations were below the world limit average for soil, which is 35 Bq/ kg for Uranium-238 and Radium-226, while Thorium-232 and Potassium-40 were above the world limit average which are 30 Bq/ kg and 400 Bq/ kg.

    Natural and artificial radionuclides and heavy metals in the surface soil of the uranium mining area of Tongliao, China, were measured using gamma spectrometry, flame atomic absorption spectrophotometry, graphite furnace atomic absorption spectrophotometry and microwave dissolution atomic fluorescence spectrometry respectively. The estimated average activity concentrations of (238)U, (232)Th, (226)Ra, (40)K and (137)Cs are 27.53±16.01, 15.89±5.20, 12.64±4.27, 746.84±38.24 and 4.23±4.76Bq/kg respectively. The estimated average absorbed dose rate in the air and annual effective dose rate are 46.58±5.26nGy/h and 57.13±6.45μSv, respectively. The radium equivalent activity, external and internal hazard indices were also calculated and their mean values are within the acceptable limits. The heavy metal concentrations of Pb, Cd, Cu, Zn, Hg and As from the surface soil were measured and their health risks were then determined. Although the content of Cd is much higher than the average background in China, its non-cancer and cancer risk indices are all within the acceptable ranges. These calculated hazard indices to estimate the potential radiological health risk in soil and the dose rate are well below their permissible limit. In addition the correlations between the radioactivity concentrations of the radionuclides and the heavy metals in soil were determined by the Pearson linear coefficient.

    Two aerial radiological surveys to measure terrestrial gamma radiation were made over an area centered on the United States Department of Energy's Feed Materials Production Center in the city of Fernald, Ohio. The Center is operated by the National Lead Company of Ohio. Gamma ray data were collected from east-west flight lines at 90 m intervals over an area 25 km 2 centered on the plant site. The small Ohio towns of Shandon, Ross, and New Baltimore were surveyed from north-south flight lines at 300 m intervals. Processed data indicated that on-site radioactivity was due primarily to radionuclides currently being handled or processed at the Center. Off-site data showed the radioactivity to be due to naturally occurring radionuclides northeast and south of the site. If the northwest corner of the survey area an unusually high count rate region of airborne radon daughter activity was encountered. This was equivalent to approximately four times the normal background. However, the follow-up survey of 1977 showed this area to be within the background count rate level

    Previous research has suggested that transformative learning can be fostered in higher education by creating active learning experiences that are directly related to content taught, are personally engaging, and can stimulate reflection. The aim of this qualitative study was to assess changes experienced by students in an e-learning dental hygiene degree completion program beyond attainment of competence-changes that may be described as transformative learning. The data used were transcripts of focus groups that had been conducted with each of the first five cohorts of students to graduate from the program; a total of 30 of the 42 students in the five cohorts (71%) participated. Using their previously developed Transformation Rubric for Engaged Learning, the authors categorized focus group data to identify changes in students' confidence, pride, skills, perceptions of the world, and personal identity at the transformative and nontransformative levels. Every participant reported at least one change; overall, the students averaged 8.3 changes. The vast majority (84%) of these changes were transformative. Middle-performing students showed a disproportionately higher rate of transformational changes in the areas of confidence and pride. The e-learning program appeared to have had a significant transformative impact on students, but additional research on the effect on middle-performing students is warranted.

    Full Text Available The teaching experience we present is closely linked to research, considered part of the action of training teachers. In the new curriculum, adapted to the European Higher Education Area and valid throughout the European continent, a Final Degree Work (TFG was introduced to the last semester of training, which must demonstrate a received comprehensive training in all subjects. We planned a TFG model in which students interrelate knowledge, professional practice and research. This type of TFG is based on the Emergent Educational Model that we have elaborated. In the current course we have carried out and analyzed four examples in which ethnomathematics is introduced as a foundation, microprojects focusing on different cultural signs are elaborated, and the interrelationship of the various sciences are reflected upon, creating awareness that research is a necessary element in teacher education. We describe the MED model of teacher education, the didactic teaching construct called micro-project, and the type of TFG designed, along with four examples thereof.

  19. Políticas curriculares descentralizadas: autonomia ou recentralização? Decentralized curricular policies: autonomy or re-centralization?

    Full Text Available No período da reforma das décadas de 1980 e 1990, a idéia das políticas curriculares descentralizadas tornou-se central no discurso educacional. O Estado poderá usar o discurso da descentralização para defender mais autonomia e responsabilidade, tal como as forças de mercado poderão empregá-lo para orientar os seus objetivos em relação às escolas. Neste artigo pretendemos identificar uma série de diferentes significados para a palavra descentralização, argumentando que o currículo é um processo intencional e prático em que os principais atores são os professores e os alunos. O ponto central é como caminharmos fora das linhas. A provável resposta introduz a centralidade da escola sem minimizar a importância das questões curriculares.The idea of decentralization became central to educational discourse during the period of reform of the late 1980s and the 1990s. The State can use the discourse of decentralization to argue in favor of greater autonomy and responsibility, just as market forces can use it to attain their objectives in regard to schools. In this article our purpose is to identify a number of different meanings of the term decentralization, arguing that decisions regarding curricula are intentional and practical processes in which students and teachers are the main actors. The key question is how to move ahead off the beaten path. The probable answer will be based on the centrality of the school without minimizing the importance of curriculum-related issues.

    Corrective Action Unit (CAU) 168 is identified in the Federal Facility Agreement and Consent Order of 1996 as Area 25 and 26 Contaminated Materials and Waste Dumps. CAU 168 consists of twelve Corrective Action Sites (CASs) in Areas 25 and 26 of the Nevada Test Site, which is approximately 105 kilometers (65 miles) northwest of Las Vegas, Nevada. The CASs contain surface and subsurface debris, impacted soil, and contaminated materials. Site characterization activities were conducted in 2002, and the results are presented in the Corrective Action Decision Document (CADD) for CAU 168 (U.S. Department of Energy, National Nuclear Security Administration Nevada Site Office [NNSA/NSO], 2006). Site characterization results indicated that soil at several sites exceeded the clean-up criteria for total petroleum hydrocarbons (TPH), polychlorinated biphenyls (PCBs), and radionuclides. The Nevada Division of Environmental Protection approved the proposed corrective actions specified in the CADD (NNSA/NSO, 2006). The approved corrective actions include no further action, clean closure, and closure in place with administrative controls

    Accurate quantification of naturally occurring radioactive materials in soil provides information on geological characteristics, possibility of petroleum and mineral exploration, radiation hazards to the dwelling populace etc. Of practical significance, the earth surface media (soil, sand and sediment) collected from the densely populated coastal area of Chittagong city, Bangladesh were analysed using a high purity germanium γ-ray spectrometer with low background radiation environment. The mean activities of 226Ra (238U), 232Th and 40K in the studied materials show higher values than the respective world average of 33, 36 and 474 Bq/kg reported by the UNSCEAR (2000). The deduced mass concentrations of the primordial radionuclides 238U, 232Th and 40K in the investigated samples are corresponding to the granite rocks, crustal minerals and typical rocks respectively. The estimated mean value of 232Th/238U for soil (3.98) and sediment (3.94) are in-line with the continental crustal average concentration of 3.82 for typical rock range reported by the National Council on Radiation Protection and Measurements (NCRP). But the tonalites and more silicic rocks elevate the mean value of 232Th/238U for sand samples amounting to 4.69. This indicates a significant fractionation during weathering or associated with the metasomatic activity in the investigated area of sand collection.

    public health required a rapid response, through research, training and structuring of the health network. Thus, occupational therapists were incorporated into the teams for infant stimulation and rehabilitation, and into the production of knowledge in the area. Objective: To describe the experience of assisting children with microcephaly by the Zika Virus, during a curricular internship of occupational therapy. Method: Reports of the curricular internship of occupational therapy. We used the clinical supervision records from the professional and academic training, during 5 months in the infectious diseases infirmary and outpatient clinic at a referral university hospital for congenital Zika virus syndrome in Recife. Results: Twenty-four infants with microcephaly, aged between 3 and 10 months, were treated. We observed neurological impairment, with delayed neuropsychomotor development, and alterations in the tonus and visual, auditory, proprioceptive, vestibular and tactile systems. Stimulation was directed towards the skills for infant development and for creating an appropriate, safe environment in which children were able to acquire motor, sensory, communication, cognitive and social skills. Guidelines for the families, making adaptations, facilitation of playing skills and activities of daily living were also carried out. Conclusion: The training period allowed us to experience the contributions of occupational therapy for the stimulation of children with microcephaly, preparing us as future professionals for the current demands and for the production of knowledge.Keywords: Microcephaly; Occupational Therapy; Early Intervention; Clinical Clerkship; Zika Virus

  3. Drivers of Dashboard Development (3-D): A Curricular Continuous Quality Improvement Approach.

    Undergraduate medical education (UME) programs are seeking systematic ways to monitor and manage their educational performance metrics and document their achievement of external goals (e.g., Liaison Committee on Medical Education [LCME] accreditation requirements) and internal objectives (institution-specific metrics). In other continuous quality improvement (CQI) settings, summary dashboard reports have been used to evaluate and improve performance. The Stony Brook University School of Medicine UME leadership team developed and implemented summary dashboard performance reports in 2009 to document LCME standards/criteria compliance, evaluate medical student performance, and identify progress in attaining institutional curricular goals and objectives. Key performance indicators (KPIs) and benchmarks were established and have been routinely monitored as part of the novel Drivers of Dashboard Development (3-D) approach to curricular CQI. The systematic 3-D approach has had positive CQI impacts. Substantial improvements over time have been documented in KPIs including timeliness of clerkship grades, midclerkship feedback, student mistreatment policy awareness, and student satisfaction. Stakeholder feedback indicates that the dashboards have provided useful information guiding data-driven curricular changes, such as integrating clinician-scientists as lecturers in basic science courses to clarify the clinical relevance of specific topics. Gaining stakeholder acceptance of the 3-D approach required clear communication of preestablished targets and annual meetings with department leaders and course/clerkship directors. The 3-D approach may be considered by UME programs as a template for providing faculty and leadership with a CQI framework to establish shared goals, document compliance, report accomplishments, enrich communications, facilitate decisions, and improve performance.

    Full Text Available We hypothesized that an interested medical student group would be helpful in reviewing tutorial cases and giving relevant feedback on the curricular integration of cross-cultural content using case triggers in a preclinical gastrointestinal pathophysiology course. Self-selected student leaders (n = 9 reviewed pre-existing problem-based learning tutorial cases (n = 3 with cross-cultural triggers, and provided narrative feedback to course faculty. The cases were modified and used for the entire class in the following 2 years. Participating course students' comments and teaching faculty feedback were also noted. Outcomes were a change in case content, student global evaluations of the course, and self-reported faculty comfort with teaching the cases. All three tutorial cases were reviewed by a separate group of 2–3 students. Major and minor revisions were made to each case based on the student feedback. These cases were used in 2007 and 2008 and were the major change to the course during that time. Overall course evaluation scores improved significantly from 2006 to 2008 (p = 0.000. Tutors (n = 22 in 2007; n = 23 in 2008 expressed relief during tutor meetings that students had reviewed the cases. A general framework for eliciting student feedback on problem-based cases was developed. Student feedback, consisting of self-selected students' case reviews and solicited course and tutor comments, added value to a curricular reform to improve the integration of cross-cultural content into a problem-based learning curriculum. Our study underscores the fundamental link between teachers and students as partners in curricular development.

    Waste is classified (art.184, sub. 1, L.D. n.152/2006) as urban or special depending on its origin and whether it is dangerous or not, as well as the degree of danger. The reuse and recycling of materials are two of the main features that characterize the concept of the circular economy. Every firm operating in the field of the circular economy should adopt an industrial approach based on resource efficiency and the use and supply of sustainable raw materials, which can be achieved through innovative technologies, innovative methodologies and new business models. GE.S.P.I, has become a leading firm in the sector of hazardous industrial waste disposal, adding value to waste through a groundbreaking technology. The result of the process is the production of energy, as well as the creation of ash; this ash is then treated in order to separate dangerous heavy metals from the ash through the technique of eddy currents. Metals and purified ash are then put on the market. The aim of this paper is the price definition of this special waste thanks to the analysis of the specific second raw materials market. In this firm, incineration is a process where emissions are strongly controlled by innovative instruments in order to excel in the social and environmental respect. Through SWOT analysis we moreover describe how a company can turn the weaknesses of a high risk area into opportunities and value becomes a useful problem solving instrument to analyze logistic, marketing, and social responsibility, in the perspective of the optimization of eco-management material flows.

El segundo, propiciado por la reflexión sobre estas prácticas en un grupo de estudio sobre diseño curricular en el Centro de Evaluación Académica de la misma Universidad. Tener el espacio para conjugar experiencia y reflexión permitió retomar labores esenciales que las y los docentes pueden realizar para transformar el currículum, si se parte de una comprensión compleja, histórica y contextual de este. Se concluye, en este sentido, que el diseño y desarrollo curricular son dos momentos inseparables, donde el cuerpo docente puede tener una participación activa y crítica. El análisis realizado, fuertemente imbricado al referente de la propia práctica, se concreta en una propuesta de acciones posibles, cuya viabilidad aumenta si el profesorado cuenta con la formación necesaria, y con una actitud permanente de autocrítica y reflexión.Abstract: This essay was elaborated by the combination of two different moments; the first one related with the experience of the author in his labor as a university educator, and as a integrant and coordinator of the Curriculum Commission of the Social Work School at the University of Costa Rica.

    Early familiarity is regarded as one of the keys to attracting female students to traditionally male professions. I will describe four different extra curricular programs that my collaborators in the local school district and I have developed for students in grades 5-12. These programs are part of a project entitled "Promoting Young Women in the Physical sciences", which also includes teacher training and programs in which parents participate with the child. Through these sustained and broad-based interventions, we provide early experiences that we expect will prove positive to students. I will also address the successes and difficulties in starting and sustaining these programs.

    2017-07-01

    Highly porous carbon nanoarchitectures (HPCNs) were derived from biomass materials, namely, corn fibers (CF), corn leafs (CL), and corn cobs (CC). We surprisingly found that by a very simple activation process the CF, CL, and CC materials can be transformed into exciting two-dimensional (2D) and three-dimensional (3D) carbon nanoarchitectures with excellent physicochemical properties. FESEM and HRTEM results confirmed a three different carbon forms (such as foams-like carbon, carbon sheets with several holes and cheese-like carbon morphology) of HPCNs. Huge surface area (2394-3475 m2/g) with excellent pore properties of HPCNs was determined by BET analysis. Well condensed graphitic plans of HPCNs were confirmed by XRD, XPS and Raman analyses. As an electrode material, HPCNs demonstrated a maximum specific capacitance (Cs) of 575 F/g in 1.0 M H2SO4 with good stability over 20,000 cycles. The CC-700 °C showed a tremendous Cs of 375 F/g even at 20000th cycles. To the best of our knowledge, this is the highest Cs by the biomass derived activated carbons in aqueous electrolytes. The CC-700 °C exhibited excellent charge-discharge behavior at various current densities (0.5-10 A g-1). Notably, CC-700 °C demonstrated an excellent Cs of 207 F/g at current density of 10 A g-1. An extraordinary change-discharge behavior was noticed at low current density of 0.5 A g-1.

    2009-01-01

    The aim of this study was to measure the students' perceptions of the educational environment in a medical school undergoing curricular transition from a traditional to a problem-based learning (PBL) program in the academic year 2006-2007. The Dundee Ready Education Environment Measure (DREEM) was used to evaluate perception of the educational environment. Multivariate logistic regression models were used to identify the factors related to educational environment perception that differ between students following a traditional curriculum to those following a PBL program at Kuwait University Medical School. Mean DREEM score was 53%. When students moved from the traditional curriculum to the PBL system, Academic Self-Perception deteriorated, while Perception of Atmosphere improved. Academic Self-Perception deteriorated because conventional strategies of learning were perceived as no longer useful, while Perception of Atmosphere improved because of increased relevance of the studies. Our findings suggest that curricular changes require careful planning and thinking, with particular attention upon how they influence the educational climate. When new teaching strategies are introduced, new factors that may lead students to develop an adverse perception of their educational environment may be introduced as well. Identification of such factors can lead to an improved educational outcome. Copyright 2009 S. Karger AG, Basel.

    Mayorga-Vega, Daniel; Viciana, Jesús

    2014-06-01

    The main purpose of this study was to evaluate the differences in adolescents´ objective physical activity levels and perceived effort in physical education, school recess, and extra-curricular organized sport by motivational profiles in physical education. A sample of 102 students 11-16 yr. old completed a self-report questionnaire assessing self-determined motivation toward physical education. Subsequently, students' objective physical activity levels (steps/min., METs, and moderate-to-vigorous physical activity) and perceived effort were evaluated for each situation. Cluster analysis identified a two-cluster structure: "Moderate motivation toward physical education profile" and "High motivation toward physical education profile." Adolescents in the second cluster had higher physical activity and perceived effort values than adolescents in the first cluster, except for METs and moderate-to-vigorous physical activity in extra-curricular sport. These results support the importance of physical education teachers who should promote self-determined motivation toward physical education so that students can reach the recommended physical activity levels.

    Full Text Available As the cultural and linguistic diversity continues to increase in Florida s K-12 public school population, the demand for teachers trained to address their unique needs becomes paramount. Previously a responsibility of Florida s school districts, ESOL(English for Speakers of Other Languages training has been delegated to colleges of education per state mandate. This mandate requires that graduates of initial teacher certification programs in the state s universities demonstrate competency in all of the 25 Florida Performance Standards for Teachers of English for Speakers of Other Languages. In order to satisfy this charge, colleges of education in Florida are following a variety of training models: stand-alone courses, curricular infusion, or a combination of the two. A large, metropolitan university in Central Florida has developed an integrated model consisting of two stand-alone courses, field experience integration of the standards, and curricular infusion of ESOL standards via on-lone modules in methods courses. The authors, who teach methods courses in which such infusion has been recently effected, surveyed their students to obtain feedback regarding the modules, the results of which are discussed in this paper.

    The new UCSF Bridges Curriculum aims to prepare students to succeed in today's health care system while simultaneously improving it. Curriculum redesign requires assessment strategies that ensure that graduates achieve competence in enduring and emerging skills for clinical practice. To design entrustable professional activities (EPAs) for assessment in a new curriculum and gather evidence of content validity. University of California, San Francisco, School of Medicine. Nineteen medical educators participated; 14 completed both rounds of a Delphi survey. Authors describe 5 steps for defining EPAs that encompass a curricular vision including refining the vision, defining draft EPAs, developing EPAs and assessment strategies, defining competencies and milestones, and mapping milestones to EPAs. A Q-sort activity and Delphi survey involving local medical educators created consensus and prioritization for milestones for each EPA. For 4 EPAs, most milestones had content validity indices (CVIs) of at least 78 %. For 2 EPAs, 2 to 4 milestones did not achieve CVIs of 78 %. We demonstrate a stepwise procedure for developing EPAs that capture essential physician work activities defined by a curricular vision. Structured procedures for soliciting faculty feedback and mapping milestones to EPAs provide content validity.

    Full Text Available Partiendo de la hipótesis de que la cuestión epistemológica referida a la construcción social del significado tiene una especial relevancia para los estudios curriculares, ya sea en relación al enfoque adoptado o a los criterios y procedimientos de selección, jerarquización y legitimación de contenidos, se realizó una investigación orientada al análisis de las cuestiones epistemológico-lingüísticas vinculadas a la problemática curricular. Se procuró explicitar los procesos de producción y legitimación del sentido y precisar el rol del lenguaje en sus funciones constitutivas y comunicativas. En especial se intentó precisar el impacto que implica en el orden educativo el llamado “giro lingüístico” y el abandono de la consideración del lenguaje como mero instrumento de transmisión de contenidos conceptuales cerrados, para adoptar un enfoque constructivo del mismo, admitiendo que los contenidos significativos se elaboran en procesos comunicativos históricamente contextuados que implican actos de resignificación.

Para responder a esta questão - objetivo deste estudo -, procedeu-se a uma pesquisa qualitativa com os discentes matriculados no quinto período do curso, por meio de entrevistas, as quais foram categorizadas e analisadas. Os resultados evidenciaram significativa receptividade ao novo modelo curricular, pelo entendimento de que este é capaz de suscitar novas reflexões dirigidas à futura prática do estudante, e, igualmente, ao conceito de saúde e ao processo de adoecimento. Verificou-se, ainda, que a opção precoce por uma especialidade, expressa pela maior parte dos entrevistados, não foi alterada sob o novo currículo e que a formação do médico como generalista ou médico de família é ainda pouco valorizada.

    Pinder, Karen E; Shabbits, Jennifer A

    2018-03-05

    The past decade has witnessed successful expansion, distribution and curricular renewal at the University of British Columbia (UBC) medical school. The expansion and distribution of the medical program doubled enrollment and established the first North American medical school training students across multiple geographical locations. The more recent competency-based curriculum renewal demonstrates sustained innovation within UBC medicine. This paper describes that a significant contributor to these successes has been a team of teaching faculty whose exclusive roles have been providing curricular support. Over the past decade, this group has evolved into a vital component of the day-to-day operations and performance of the distributed medical curriculum; they now provide continuity in leadership and innovation across multiple educational facets of the program. This paper reports on the evolution and significance of these faculty members. The descriptions establish the success of an investment in teaching faculty and underscore the importance of engaging faculty whose primary commitments are to teaching, educational pedagogy, and student support. This efficacious model of supporting and advancing a complex distributed medical program over more than a decade of pivotal change will be of interest to faculties and programs that are contemplating or navigating similar pursuits.

    Background: There is a serious lack of young doctors in trauma surgery, which has intensified in recent years. The reasons are complex. Studies have shown that the interest in starting a career in surgery significantly decreases during medical school. To counteract the lack of young talent in the clinic, interest in the subject should be aroused in medical school. The aim of the present study was to evaluate current teaching at our university, where trauma surgery is a curricular subject with mandatory attendance for all medical students. Material and Methods: The current curriculum is intended for medicine students in their fifth year. The curriculum comprises lectures, practical courses and observation modules held in small groups. Students are provided with an experienced surgeon as teacher and mentor for the whole week. A teaching and training centre is available for the practical courses. In an anonymised questionnaire, students were asked about their overall assessment and the training success of practical and theory-oriented modules, as well as their specific interest in traumatology. Results: The evaluated curriculum gave very good results, with an overall rating of 1.53 (average) on a 6-point Likert scale in the overall assessment. It could be shown that students previously not interested in starting a career in trauma surgery showed significantly more interest in the subject after the curriculum. The practical parts scored best in the individual assessment. Conclusion: We showed that intensive teaching can arouse interest in traumatology in students who had been indifferent to orthopaedics and traumatology. Georg Thieme Verlag KG Stuttgart · New York.

    Highlights: • Simple templating carbonization method was developed to obtain porous carbons. • Surface etching by KOH activation greatly boosts surface area and carbon purity. • The as-obtained porous carbon delivers a high capacitance of 275 F g{sup −1}. • Symmetric supercapacitor can achieved high energy density and power density. - Abstract: Large surface area and good structural stability, for porous carbons, are two crucial requirements to enable the constructed supercapacitors with high capacitance and long cycling lifespan. Herein, we successfully prepare porous carbon with a large surface area (3175 m{sup 2} g{sup −1}) and an ultrahigh carbon purity (carbon atom ratio of 98.25%) via templating carbonization coupling with KOH activation. As-synthesized MTC-KOH exhibits excellent performances as supercapacitor electrode materials in terms of high specific capacitance and ultrahigh cycling stability. In a three electrode system, MTC-KOH delivers a high capacitance of 275 F g{sup −1} at 0.5 A g{sup −1} and still 120 F g{sup −1} at a high rate of 30 A g{sup −1}. There is almost no capacitance decay even after 10,000 cycles, demonstrating outstanding cycling stability. In comparison, pre-activated MTC with a hierarchical pore structure shows a better rate capability than microporous MTC-KOH. Moreover, the constructed symmetric supercapacitor using MTC-KOH can achieve high energy densities of 8.68 Wh kg{sup −1} and 4.03 Wh kg{sup −1} with the corresponding power densities of 108 W kg{sup −1} and 6.49 kW kg{sup −1}, respectively. Our work provides a simple design strategy to prepare highly porous carbons with high carbon purity for supercapacitors application.

    In 2009, to support an evaluation of the feasibility of reopening the Pearce Creek Dredge Material Containment Area (DMCA) in Cecil County, Maryland, for dredge-spoil disposal, the U.S. Geological Survey (USGS) began to implement a comprehensive study designed to improve the understanding of the hydrogeologic framework, hydrology, and water quality of shallow aquifers underlying the DMCA and adjacent communities, to determine whether or not the DMCA affected groundwater quality, and to assess whether or not groundwater samples contained chemical constituents at levels greater than maximum allowable or recommended levels established by the U.S. Environmental Protection Agency Safe Drinking Water Act. The study, conducted in 2010-11 by USGS in cooperation with the U.S. Army Corps of Engineers, included installation of observation wells in areas where data gaps led earlier studies to be inconclusive. The data from new wells and existing monitoring locations were interpreted and show the DMCA influences the groundwater flow and quality. Groundwater flow in the two primary aquifers used for local supplies-the Magothy aquifer and upper Patapsco aquifer (shallow water-bearing zone)-is radially outward from the DMCA toward discharge areas, including West View Shores, the Elk River, and Pearce Creek Lake. In addition to horizontal flow outward from the DMCA, vertical gradients primarily are downward in most of the study area, and upward near the Elk River on the north side of the DMCA property, and the western part of West View Shores. Integrating groundwater geochemistry data in the analysis, the influence of the DMCA is not only a source of elevated concentrations of dissolved solids but also a geochemical driver of redox processes that enhances the mobilization and transport of redox-sensitive metals and nutrients. Groundwater affected by the DMCA is in the Magothy aquifer and upper Patapsco aquifer (shallow water-bearing zone). Based on minimal data, the water quality

    Full Text Available As orientações curriculares e pedagógicas para a formação do profissional de nutrição receberam influência da dinâmica das transformações do ensino superior no Brasil. Em 2001, o Ministério da Educação instituiu as diretrizes curriculares nacionais para os cursos de graduação da área da saúde, em consonância com a Lei de Diretrizes e Bases da Educação. As diretrizes curriculares conformam uma nova baliza para o ensino em saúde a partir da extinção do currículo mínimo, considerado demasiadamente teórico, rígido e inflexível, não atendendo às exigências particulares de cada região, instituição ou curso, bem como às demandas sociais. As diretrizes curriculares representam ainda o desejo de superação da hegemonia do modelo biomédico e do ensino centrado no professor.

    Cardona Tomassini, Ivan Javier

    En esta investigacion se estudio el fenomeno del conocimiento de contenido y el conocimiento curricular de maestros de matermaticas y como estos dos componentes se reflejan en su conocimiento pedagogico del contenido. El conocimiento de contenido es el conocimiento que tienen los maestros de los contenidos de una disciplina y sobre la estructura de su organizacion (Shulman, 1986). El conocimiento curricular es el conocimiento que los maestros poseen sobre los componentes de un curriculo disenado para ensenar un topico de una materia especifica a un nivel particular, la variedad de instrumentos instruccionales disponibles para implementar el mismo y como utilizar los instrumentos curriculares disponibles (Ball & Bass, 2003; Choppin, 2009; Hill, Rowan, & Ball, 2005). Este estudio se enmarca en el paradigma cualitativo, teniendo como diseno el estudio fenomenologico (Lucca y Berrios, 2009; McMillan, 2004). Los participantes fueron seis maestros de matermaticas del nivel superior (10mo a 12mo grado). Al momento de la investigacion los participantes ensenaban en escuelas publicas o privadas de Puerto Rico. Para recolectar la informacion se utilizo un grupo focal en donde los maestros resolvieron seis ejercicios matematicos y posteriormente reflexionaron en forma grupal sobre las soluciones. Tambien se realizo un analisis de documentos de planificacion y se llevaron a cabo entrevistas semiestructuradas. Se exploraron los contenidos relacionados a la ecuacion de una recta, rectas verticales y horizontales, suma y multiplicacion de polinomios, resolucion de ecuaciones cuadraticas y distancia entre dos puntos del plano cartesiano. Los resultados muestran que los participantes tienen dominio procesal de los contenidos correspondientes a las rectas verticales y horizontales, la suma y multiplicacion de polinomios, el calculo distancia entre dos puntos del plano cartesiano.

    Bedside teaching is an important element of undergraduate medical education. However, the impact of curricular course structure on student outcome needs to be determined. This study assessed changes in fourth-year medical students' evaluations of clinical teaching sessions before and after the introduction of a new course format. The curricular structure of bedside teaching sessions in cardiology was modified without changing the amount of teaching time. Clinical teachers were instructed about the new teaching format and learning objectives. The new format implemented for adult but not paediatric cardiology sessions was piloted with 143 students in winter 2007/08. By computing effect sizes, evaluation results were compared to data obtained from 185 students before the intervention. Significant rating increases were observed for adult cardiology teaching sessions (Cohen's d = 0.66) but not paediatric cardiology sessions (d = 0.22). In addition to improving the structure and organization of the course, the intervention significantly impacted on students' perceptions of their learning outcome regarding practical skills (d = 0.69). Minimal curricular changes combined with basic faculty development measures significantly increase students' perception of learning outcome. Curricular structure needs to be considered when planning bedside teaching sessions in medical undergraduate training.

    Rigorous curricular review of post-graduate veterinary medical residency programs is in the best interest of program directors in light of the requirements and needs of specialty colleges, graduate school administrations, and other stakeholders including prospective students and employers. Although minimum standards for training are typically provided by specialty colleges, mechanisms for evaluation are left to the discretion of program directors. The paucity of information available describing best practices for curricular assessment of veterinary medical specialty training programs makes resources from other medical fields essential to informing the assessment process. Here we describe the development of a rubric used to evaluate courses in a 3-year American College of Laboratory Animal Medicine (ACLAM)-recognized residency training program culminating in a Master of Science degree. This rubric, based on examples from medical education and other fields of graduate study, provided transparent criteria for evaluation that were consistent with stakeholder needs and institutional initiatives. However, its use caused delays in the curricular review process as two significant obstacles to refinement were brought to light: variation in formal education in curriculum design and significant differences in teaching philosophies among faculty. The evaluation process was able to move forward after institutional resources were used to provide faculty development in curriculum design. The use of a customized rubric is recommended as a best practice for curricular refinement for residency programs because it results in transparency of the review process and can reveal obstacles to change that would otherwise remain unaddressed.

    The aim of the present clinical trial was to analyze, through spectrophotometric digital technology, the influence of the abutment material on the color of the peri-implant soft tissue in patients with thin gingival biotype. Thirty-seven patients received an endosseous dental implant in the anterior maxilla. At time of each definitive prosthesis delivery, an all-ceramic crown has been tried on gold, titanium and zirconia abutment. Peri-implant soft-tissue color has been measured through a spectrophotometer after the insertion of each single abutment. Also facial peri-implant soft-tissue thickness was measured at the level of the implant neck through a caliper. A specific software has been utilized to identify a standardized tissue area and to collect the data before the statistical analysis in Lab* color space. ΔE parameters of the selected abutments were tested for correlation with mucosal thickness. Pearson correlation test was used. Only 15 patients met the study inclusion criteria on peri-implant soft-tissue thickness. Peri-implant soft-tissue color was different from that around natural teeth, no matter which type of restorative material was selected. Measurements regarding all the abutments were above the critical threshold of ΔE 8.74 for intraoral color distinction by the naked eye. The ΔE mean values of gold and zirconium abutments were similar (11.43 and 11.37, respectively) and significantly lower (P = 0.03 and P = 0.04, respectively) than the titanium abutment (13.55). In patients with a facial soft-tissue thickness ≤2 mm, the ΔE mean value of gold and zirconia abutments was significantly lower than that of titanium abutments (P = 0.03 and P = 0.04, respectively) and much more close to the reference threshold of 8.74. For peri-implant soft tissue of ≤2 mm, gold or zirconia abutments could be selected in anterior areas treatment. Moreover, the thickness of the peri-implant soft tissue seemed to be a crucial factor in the abutment impact

    We report the development of Co9S8 nanocrystals as a cost-effective cathode material that can be readily combined with spraying techniques to fabricate large-area dye-sensitized solar cell (DSSC) devices and can be further connected with series or parallel cell architectures to obtain a relatively high output voltage or current. A gram-scale synthesis of Co9S8 nanocrystal is carried out via a noninjection reaction by mixing anhydrous CoCl2 with trioctylphosphine (TOP), dodecanethiol and oleylamine (OLA) at 250 °C. The Co9S8 nanocrystals possess excellent catalytic ability with respect to I(-)/I3(-) redox reactions. The Co9S8 nanocrystals are prepared as nanoinks to fabricate uniform, crack-free Co9S8 thin films on different substrates by using a spray deposition technique. These Co9S8 films are used as counter electrodes assembled with dye-adsorbed TiO2 photoanodes to fabricate DSSC devices having a working area of 2 cm(2) and an average power conversion efficiency (PCE) of 7.02 ± 0.18% under AM 1.5 solar illumination, which is comparable with the PCE of 7.2 ± 0.12% obtained using a Pt cathode. Furthermore, six 2 cm(2)-sized DSSC devices connected in series output an open-circuit voltage of 4.2 V that can power a wide range of electronic devices such as LED arrays and can charge commercial lithium ion batteries.

    Full Text Available The engagement observed by the players of the games that they play is a desirable quality that has not gone unnoticed in the field of education, leading to concepts such as gamification of education, game-based learning and serious games for training. Game designer Sid Meier is often cited as defining games as being ‘a series of interesting decisions’. The concept of choice implies an autonomous selection from a constrained set of options. This article reflects on the impact of autonomy and constraints, and extrinsic and intrinsic motivators on students’ software development work during both curricular and extracurricular activities. Finally, a model for the design of games for game-based learning is proposed in terms of autonomy and constraints with respect to learning outcomes.

  4. Fate and transport processes controlling the migration of hazardous and radioactive materials from the Area 5 Radioactive Waste Management Site (RWMS)

    Estrella, R.

    1994-10-01

    Desert vadose zones have been considered as suitable environments for the safe and long-term isolation of hazardous wastes. Low precipitation, high evapotranspiration and thick unsaturated alluvial deposits commonly found in deserts make them attractive as waste disposal sites. The fate and transport of any contaminant in the subsurface is ultimately determined by the operating retention and transformation processes in the system and the end result of the interactions among them. Retention (sorption) and transformation are the two major processes that affect the amount of a contaminant present and available for transport. Retention processes do not affect the total amount of a contaminant in the soil system, but rather decrease or eliminate the amount available for transport at a given point in time. Sorption reactions retard the contaminant migration. Permanent binding of solute by the sorbent is also possible. These processes and their interactions are controlled by the nature of the hazardous waste, the properties of the porous media and the geochemical and environmental conditions (temperature, moisture and vegetation). The present study summarizes the available data and investigates the fate and transport processes that govern the migration of contaminants from the Radioactive Waste Management Site (RWMS) in Area 5 of the Nevada Test Site (NTS). While the site is currently used only for low-level radioactive waste disposal, past practices have included burial of material now considered hazardous. Fundamentals of chemical and biological transformation processes are discussed subsequently, followed by a discussion of relevant results

    To assess the image quality and diagnostic accuracy of 320-row area detector CT (320-ADCT) coronary angiography using 40 mL of contrast material in comparison with 60-mL protocol. This retrospective study included 183 patients who underwent 320-ADCT coronary angiography using 40 mL of contrast and additional 183 sex- and body mass index-matched patients using 60 mL of contrast constituting the control group. Both groups used the same 5-mL/sec injection rate. Quantitative image quality measurements and diagnostic accuracies were calculated and compared. Mean attenuation and contrast-to-noise ratio (CNR) at the aorta and all coronary arteries were lower in the 40-mL group than in the 60-mL group (all, p < 0.05), except for the CNR at proximal coronary arteries at 100 kVp (p = 0.073). However, the proportion of coronary segments with vessel attenuation >250 HU was not different between groups (all, p > 0.05), except for distal coronary arteries at 80 kVp (p = 0.001). Furthermore, there were no differences in per-patient and per-segment diagnostic accuracies between the groups (all, p > 0.05). 320-ADCT coronary angiography using 40 mL of contrast showed image quality and diagnostic accuracy comparable to the 60-mL protocol, demonstrating the clinical feasibility of lowering the risk of contrast-induced nephropathy through contrast volume reduction.

    Beginning in 2005, the Doctor of Veterinary Medicine program at the University of California underwent major curricular review and reform. To provide information for others that follow, we have documented our process and commented on factors that were critical to success, as well as factors we found surprising, difficult, or problematic. The review and reform were initiated by the Executive Committee, who led the process and commissioned the committees. The planning stage took 6 years and involved four faculty committees, while the implementation stage took 5 years and was led by the Curriculum Committee. We are now in year 2 of the institutionalizing stage and no longer refer to our reform as the "new curriculum." The change was driven by a desire to improve the curriculum and the learning environment of the students by aligning the delivery of information with current teaching methodologies and implementing adult learning strategies. We moved from a department- and discipline-based curriculum to a school-wide integrated block curriculum that emphasized student-centered, inquiry-based learning. A limit was placed on in-class time to allow students to apply classroom knowledge by solving problems and cases. We found the journey long and arduous, requiring tremendous commitment and effort. In the change process, we learned the importance of adequate planning, leadership, communication, and a reward structure for those doing the "heavy lifting." Specific to our curricular design, we learned the importance of the block leader role, of setting clear expectations for students, and of partnering with students on the journey.

    Climate change, pollution, and energy insecurity are among the greatest problems of our time. Addressing them requires major changes in our energy infrastructure. Here, we analyze the feasibility of providing worldwide energy for all purposes (electric power, transportation, heating/cooling, etc.) from wind, water, and sunlight (WWS). In Part I, we discuss WWS energy system characteristics, current and future energy demand, availability of WWS resources, numbers of WWS devices, and area and material requirements. In Part II, we address variability, economics, and policy of WWS energy. We estimate that {approx}3,800,000 5 MW wind turbines, {approx}49,000 300 MW concentrated solar plants, {approx}40,000 300 MW solar PV power plants, {approx}1.7 billion 3 kW rooftop PV systems, {approx}5350 100 MW geothermal power plants, {approx}270 new 1300 MW hydroelectric power plants, {approx}720,000 0.75 MW wave devices, and {approx}490,000 1 MW tidal turbines can power a 2030 WWS world that uses electricity and electrolytic hydrogen for all purposes. Such a WWS infrastructure reduces world power demand by 30% and requires only {approx}0.41% and {approx}0.59% more of the world's land for footprint and spacing, respectively. We suggest producing all new energy with WWS by 2030 and replacing the pre-existing energy by 2050. Barriers to the plan are primarily social and political, not technological or economic. The energy cost in a WWS world should be similar to that today. - Research highlights: {yields} Replacing world energy with wind, water, and sun (WWS) reduces world power demand 30%. {yields} WWS for world requires only 0.41% and 0.51% more world land for footprint and spacing, respectively. {yields} Practical to provide 100% new energy with WWS by 2030 and replace existing energy by 2050.

    Moore, K. D.

    2014-12-01

    The co-curricular summer research program, in which I was involved over three summers as an undergraduate student, greatly benefited me. In this paper I will briefly describe the program and how the experience contributed to my value and growth. The U.S. Department of Energy operated the Global Change Education Program (GCEP), from 1999-2013, as an outreach to both undergraduate and graduate students. Its goals were to: provide students with hands-on research experience in a one-on-one setting with leaders in global change fields, encourage undergraduate students to enter graduate school, and increase the number of high quality U.S. scientists. I took part in GCEP as a Summer Undergraduate Research Experience (SURE) Fellow. Each Fellow was teamed with a scientist to conduct research over the summer. I spent one summer at Pacific Northwest National Laboratory in Richland, WA working with Dr. William Shaw. The next two summers I spent working at Aerodyne Research, Inc. in Billerica, MA with Dr. Leah Williams. My experiences as a SURE Fellow have benefitted me in many ways. The research presentations, required of SURE Fellows, helped to improve my presentation skills. The GCEP workshops expanded the scope of my knowledge about global change impacts at all scales. I was involved in two large, collaborative field studies, which provided experiences and examples that have helped me lead my own field studies. I took part in well-functioning research teams, helping me see the value of open communication in collaborative work. My critical and analytical thinking abilities were continually honed. My problem solving skills were challenged in laboratory and field work. I worked with talented professionals and students that are now part of my professional network. My contributions resulted in being a coauthor on two peer-reviewed publications. I was able to experience research teams outside of academia, which included government and private sectors.

    Full Text Available Available documentary and research evidences reveal that the majority of Tanzania universities’ graduates (public and private universities lack competencies or technical skills (employability skills required for the job market and by potential employers, despite massive curricular reforms implemented in the public higher education sector since the early 1990s. Lack of employability skills which consequently leads to graduate unemployment or un-employability is attributable to the fact that curricular reforms and design in Tanzania public universities undertaken by lecturers and professors do not incorporate basic Tuning principles of competence-based teaching and learning which puts emphasis on competencies and skills by identifying generic and specific competencies during course design or curriculum reform. This study using the University of Dar es Salaam (UDSM’s School of Education sought to: (1 explore faculty and students’ views on the application of the Tuning approach in curricular reforms and degree/course design as a mitigation of university graduates’ unemployment and un-employability, (2 solicit stakeholders’(academic staff and students perceptions of Tuning approach and its relevance in higher education curriculum reforms and design to make higher education more competence-based, and (3 find out students perceived causes of graduate unemployment and un-employability and whether the application of Tuning approach in curriculum reforms and design in universities can be a solution to graduate unemployment. Findings from the study reveal that both faculty and students concur that application of Tuning approach in higher education reforms and curricular design could enhance graduates competences and skills and reduce graduate unemployment.First published online: 30 November 2017

  11. A curricular frame for physics education: Development, comparison with students' interests, and impact on students' achievement and self-concept

    Häussler, Peter; Hoffmann, Lore

    2000-11-01

    This article presents three interlinked studies aimed at: (1) developing a curricular frame for physics education; (2) assessing the students' interest in the contents, contexts, and activities that are suggested by that curricular frame; and (3) developing a curriculum that is in line with that frame and measuring its cognitive and emotional effects on students. The curricular frame was developed by adopting the Delphi technique and drawing on the expertise of 73 persons selected according to specified selection criteria. Interest data of some 8000 students and information of the presently taught physics curriculum were sampled longitudinally as well as cross-sectionally in various German Länder (states) by questionnaire. The third study comprised 23 experimental and 7 control classes. As a result of the comparison between the features of the curricular frame, the interest structure of students, and the current physics curriculum, there is a remarkable congruency between students' interest in physics and the kind of physics education identified in the Delphi study as being relevant. However, there is a considerable discrepancy between students' interest and the kind of physics instruction practiced in the physics classroom. Regression analysis revealed that students' interest in physics as a school subject is hardly related to their interest in physics, but mainly to the students' self-esteem of being good achievers. The data strongly suggest physics be taught so that students have a chance to develop a positive physics-related self-concept and to link physics with situations they encounter outside the classroom. A curriculum based on these principles proved superior compared to a traditional curriculum.

    Conclusions: The literature is limited to the evaluation of explicit curricula. The wider cultural competence literature offers further insight by highlighting the importance of broad and embedded forces including social influences, the institutional climate, and the implicit, or hidden, curriculum. A combined interpretation of the complementary cultural competence and sexual and gender diversity literature provides a novel understanding of the optimal content and context for the delivery of a successful curricular initiative.

    In competency-based medical education, the focus of assessment is on learner demonstration of predefined outcomes or competencies. One strategy being used in internal medicine (IM) is applying curricular milestones to assessment and reporting milestones to competence determination. The authors report a practical method for identifying sets of curricular milestones for assessment of a landmark, or a point where a resident can be entrusted with increased responsibility. Thirteen IM residency programs joined in an educational collaborative to apply curricular milestones to training. The authors developed a game using Q-sort methodology to identify high-priority milestones for the landmark "Ready for indirect supervision in essential ambulatory care" (EsAMB). During May to December 2010, the programs'ambulatory faculty participated in the Q-sort game to prioritize 22 milestones for EsAMB. The authors analyzed the data to identify the top 8 milestones. In total, 149 faculty units (1-4 faculty each) participated. There was strong agreement on the top eight milestones; six had more than 92% agreement across programs, and five had 75% agreement across all faculty units. During the Q-sort game, faculty engaged in dynamic discussion about milestones and expressed interest in applying the game to other milestones and educational settings. The Q-sort game enabled diverse programs to prioritize curricular milestones with interprogram and interparticipant consistency. A Q-sort exercise is an engaging and playful way to address milestones in medical education and may provide a practical first step toward using milestones in the real-world educational setting.

    This study describes a qualitative research design that focuses on nursing students who were aligned to different extra-curricular groups (a student representative committee, a Nurses' Day Committee and a magazine editorial team) within the School of Health. The study explores the nursing students' experiences and perceptions of belonging to an extra-curricular group within a pre-registration nursing course. Data were collected using focus groups. The findings of this study suggest that students who are members of extra-curricular groups perceive group membership to have many positive benefits. The findings were grouped into three main themes namely: employability, retention and personal gain. The findings suggest that students are clearly aware of their career development and expressed how group membership meant they were able to develop skills around employability. Students highlighted that they gained support and built lasting relationships through the groups which supported and reassured them which it was felt enabled them to progress successfully through the course. These themes reinforce the value of having established groups within a pre-registration curriculum. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available The topic of the study consists in the analysis of the „story“ of the Czech curricular reform based on the comparison of its concepts and logic with the results of educational and psychological research in teaching and learning. The first part attempts to prove that the failure of the reform mostly rejected by teachers doesn’t consist in the lack of communication with them. The following part reveals the old tension between thinking/student oriented vs. subject oriented teaching behind current reform clichés. As the core and the symbol of the curricular reform, the notion of competence is critically analyzed: it is a bad answer, because it is not research evidence-based, to a good question. The last part deals with three issuesfrom psychological research the results of which the reform largely ignored:(1 predominant focus on problem solving ignoring the results of research on the relationship between working memory and long-term memory and in the cognitive-load theory, (2 stress on the transversal competences as the goal of teaching ignoring the narrow and strong link of the thinking skills with the specific object of thinking and its epistemological constraints, and (3 challenging the belief the (far transfer could play the role of the criterion of the learning effectiveness. Thus, the curricular reform was more ideology-driven than evidence-based.

    Full Text Available The demands of the job market in the information field trigger the need to improve professional practices that refer to the curricular reform, due to the formation of competent professionals that meet the social needs. Archivists, when categorized as information professionals, also fit into this context, and must acquire the status of a Modern Information Professional (MIP. Thus, this study analyzes the skills of the MIP relating them to the archivist, based on literature and curricular training. Investigates in literature what has been published about the MIP; Compares MIP's skills to the archivist's; And investigates these skills in the field of archival training. Methodologically, a review of the MIP's skills and its relations to the archivists' and analysis of ten curricula of Brazilian archival schools was carried out, in order to detect subjects focused on the construction of MIP skills. After theoretical and documentary research, it was noticed that most of the studies (80% compare the MIP to the librarian. The literature is scarce (10% by directing the MIP to the archivist, but also without delineating it to specific professionals (10%. As for the academic formation, the schools, in general lines, offer subjects, whose curricular approach contemplates the four competences of the MIP. It was found that schools recognize the need to extend the skills of archivists to the point where they become MIPs, in order to adapt to the new challenges posed by the job market.
