    2005-01-01

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

    The Department of Energy has defined a safeguards system to be an integrated system of physical protection, material accounting and material control subsystems designed to deter, prevent, detect, and respond to unauthorized possession, use, or sabotage of SNM. In practice, safeguards involve the development and application of techniques and procedures dealing with the establishment and continued maintenance of a system of activities. The system must also include administrative controls and surveillance to assure that the procedures and techniques of the system are effective and are being carried out. The control of nuclear material is critical to the safeguarding of nuclear materials within the United States. The U.S. Department of Energy includes as part of material control four functional performance areas. They include access controls, material surveillance, material containment and detection/assessment.

    The NCTM vision shows the importance of two things in school mathematics, which is knowing the mathematics of the 21st century and the need to continue to improve mathematics education to answer the challenges of a changing world. One of the competencies associated with the great challenges of the 21st century is the use of help and tools (including IT), such as: knowing the existence of various tools for mathematical activity. One of the significant challenges in mathematical learning is how to teach students about abstract concepts. In this case, technology in the form of mathematics learning software can be used more widely to embed the abstract concept in mathematics. In mathematics learning, the use of mathematical software can make high level math activity become easier accepted by student. Technology can strengthen student learning by delivering numerical, graphic, and symbolic content without spending the time to calculate complex computing problems manually. The purpose of this research is to design and develop teaching materials software assisted for numerical method. The process of developing the teaching material starts from the defining step, the process of designing the learning material developed based on information obtained from the step of early analysis, learners, materials, tasks that support then done the design step or design, then the last step is the development step. The development of teaching materials software assisted for numerical methods is valid in content.

    Directory of Open Access Journals (Sweden)

    Jones P

    2015-06-01

    Full Text Available Patrick Jones, Bhavan Prasad Rai Department of Surgery, Ninewells Hospital, Dundee, UK Purpose: Bedside teaching holds a strong tradition as a key-learning platform for clinical examination in the basic medical clerkship. There is a growing body of literature expressing concern for its witnessed decline in medical school curricula. However, the views of students toward this patient-centered cornerstone in surgical education remain under-reported. The purpose of this study was to gain a nationwide perspective on bedside teaching according to medical students in the United Kingdom. Materials and methods: An adapted Delphi method was employed to formulate the question series as part of a multi-step process including a pilot study, which was used to construct this survey. The target population was medical undergraduates in the United Kingdom and participants were recruited via social media. Outcomes assessed included exposure to bedside teaching, perceived benefits of clinical simulation, and junior doctors as clinical teachers. Barriers to clinical examination were also evaluated. Results: Overall, 368 completed surveys were received (completion rate 98.9%. Final year students were significantly more likely to report receiving insufficient bedside teaching (P<0.01. Seventy-eight percent of the study group agreed that clinical simulation is a good learning tool for clinical examination. Seventy percent of students felt junior doctors were as able as senior doctors to teach. Lack of confidence was identified as the commonest barrier to overcome when examining patients and two-thirds of students felt they burdened patients during bedside teaching. Conclusion: This prospective study confirms the exposure deficit, which medical students experience in bedside teaching. The junior doctor represents a dynamic clinical teacher in the face of working time directives. Peer learning is a novel solution to such pressures. Work is needed to re-establish the

  2. Teaching materials for radiation training and user guides

    International Nuclear Information System (INIS)

    Furuta, Etsuko; Kusama, Keiji

    2014-01-01

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

    Makarious, Nader N.

    Chemistry is a highly abstract discipline that is taught and learned with the aid of various models. Among the most challenging, yet a fundamental topic in general chemistry at the high school level, is molecular geometry. This study focused on developing exemplary educative curriculum materials pertaining to the topic of molecular geometry. The methodology used in this study consisted of several steps. First, a diverse set of models were analyzed to determine to what extent each model serves its purpose in teaching molecular geometry. Second, a number of high school teachers and college chemistry professors were asked to share their experiences on using models in teaching molecular geometry through an online questionnaire. Third, findings from the comparative analysis of models, teachers’ experiences, literature review on models and students’ misconceptions, the curriculum expectations of the Next Generation Science Standards and their emphasis on three-dimensional learning and nature of science (NOS) contributed to the development of the molecular geometry unit. Fourth, the developed unit was reviewed by fellow teachers and doctoral-level science education experts and was revised to further improve its coherence and clarity in support of teaching and learning of the molecular geometry concepts. The produced educative curriculum materials focus on the scientific practice of developing and using models as promoted in the Next Generations Science Standards (NGSS) while also addressing nature of science (NOS) goals. The educative features of the newly developed unit support teachers’ pedagogical knowledge (PK) and pedagogical content knowledge (PCK). The unit includes an overview, teacher’s guide, and eight detailed lesson plans with inquiry oriented modeling activities replete with models and suggestions for teachers, as well as formative and summative assessment tasks. The unit design process serves as a model for redesigning other instructional units in

    Tooth morphology is a central component of the dental curriculum and is applicable to all dental specialities. Traditional teaching methods are being supplemented with innovative strategies to tailor teaching and accommodate the learning styles of the recent generation of students. An online survey was compiled and distributed to the staff involved in teaching tooth morphology in the United Kingdom and Ireland to assess the importance of tooth morphology in the dentistry curriculum and the methodologies employed in teaching. The results of the survey show that tooth morphology constitutes a small module in the dental curriculum. It is taught in the first 2 years of the dental curriculum but is applicable in the clinical years and throughout the dental career. Traditional teaching methods, lecture and practical, are being augmented with innovative teaching including e-learning via virtual learning environment, tooth atlas and e-books leading to blended learning. The majority of the schools teach both normal dental anatomy and morphologic variations of dental anatomy and utilise plastic teeth for practical and examination purposes. Learning the 3D aspects of tooth morphology was deemed important by most of the respondents who also agreed that tooth morphology is a difficult topic for the students. Despite being core to the dental curriculum, overall minimal time is dedicated to the delivery of tooth morphology, creating a reliance on the student to learn the material. New forms of delivery including computer-assisted learning tools should help sustain learning and previously acquired knowledge. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Science.gov (United States)

    2014-04-01

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

    2017-04-01

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

    2018-04-10

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

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

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

    2007-05-01

    The United States has many different scientific agencies that fund research on solar science, including the National Aeronautics and Space Agency (NASA) and the National Science Foundation (NSF). Because there is a large population of Spanish-speaking people in the US, some of the resources developed by the education components of research projects take into account broader cultural perspectives on science and are developed in Spanish. We will describe the education and outreach programs of three solar programs funded by NASA and NSF, the Solar TErrestrial RElations Observatory (STEREO) program, the "We Are One Under the Sun" Program, and the National Optical Astronomy Observatory (NOAO) education program. The STEREO program aims to teach about the Sun through different venues including teacher workshops and courses, teacher materials, turning solar data from STEREO into sound, working with museums, and creating solar posters, CDs, DVDs, and lenticulars. The "We are One Under the Sun" program focuses on Native Americans and Hispanics of Native heritage. It works by merging culture, ancient observatories, and the latest NASA solar science to engage children, youth, and the general public in science and technology through solar traditions in their own indigenous culture. The NOAO Educational Outreach Program was established to make the science and scientists of NOAO more accessible to the K-12 and college-level communities. We will focus on the NOAO solar projects and Spanish-Language Astronomy Materials Educational Center program, which provides multiple types of Spanish- language materials for teachers. These programs have had different levels of outreach in Spanish-speaking countries, namely Mexico (STEREO and "We are One Under the Sun") and Chile (NOAO). We will describe these efforts and give links to the Spanish and English resources available to learn and teach about the Sun.

    Full Text Available In this paper, the goal is to analyse history textbooks (LDH used by Elementary School (6th grade in rural schools located in the municipality of Tocantinópolis-TO. Considering that the training in the Rural Education perspective has made it possible to recognize and value knowledge and culture, seeking the emancipation of the peasants, this investigation of the selected teaching material includes an analysis of the following elements of the textbooks: (1 contents; (2 activities; (3 teacher-student interaction; and (4 images. The research is of bibliographic nature and qualitative approach. The corpus consists of two LDHs: one produced for the Programa Escola Ativa and another for schools located in urban areas, but also used in the rural schools of research context. In view of the reality of rural schools and the social, political and economic context in which the peasants have lived, the research results have revealed that only one of the LDHs analyzed follows the principles defended by Rural Education.

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

  7. Enhanced teaching and student learning through a simulator-based course in chemical unit operations design

    Science.gov (United States)

    Ghasem, Nayef

    2016-07-01

    This paper illustrates a teaching technique used in computer applications in chemical engineering employed for designing various unit operation processes, where the students learn about unit operations by designing them. The aim of the course is not to teach design, but rather to teach the fundamentals and the function of unit operation processes through simulators. A case study presenting the teaching method was evaluated using student surveys and faculty assessments, which were designed to measure the quality and effectiveness of the teaching method. The results of the questionnaire conclusively demonstrate that this method is an extremely efficient way of teaching a simulator-based course. In addition to that, this teaching method can easily be generalised and used in other courses. A student's final mark is determined by a combination of in-class assessments conducted based on cooperative and peer learning, progress tests and a final exam. Results revealed that peer learning can improve the overall quality of student learning and enhance student understanding.

    1987-01-01

    The United States currently does not have formal design criteria for qualifying ductile cast iron (DCI) transportation casks. There is also no dedicated material standard for DCI for this particular application. Recognizing the importance of a material standard for this application, Lawrence Livermore Laboratories, in a report to the NRC, recommended that steps be taken to develop an ASTM material specification suitable for spent fuel shipping containers. A draft ASTM material specification has been written and is currently in the ASTM approval process. This paper reviews the brief history of the development of the specification, the technical basis for the material properties, the ASTM approval process and the current status of the draft specification. The expected implications of having an adopted ASTM specification on the licensing process are also discussed. The relationship of fracture toughness to composition, microstructure and tensile properties has been evaluated at Sandia National Laboratories. The first main conclusion reached is that static fracture toughness is essentially decoupled from tensile properties such as yield strength, tensile strength and ductility. The significance of this finding is that tensile properties provided for in existing DCI specifications should not be used as an indicator of a material's ability to resist crack initiation. A material specification which includes fracture toughness requirements is needed to address the brittle fracture concerns. Second, static fracture toughness was found to correlate well with material microstructure; specifically, graphite nodule count or nodule spacing

    1998-01-01

    The flows of nonfood and nonfuel materials through the economy have significant impact on our lives and the world around us. Growing populations and economies demand more goods, services, and infrastructure. Since the beginning of the twentieth century, the types of materials consumed in the United States have significantly changed. In 1900, on a per-weight basis, almost half of the materials consumed were from renewable resources, such as wood, fibers, and agricultural products, the rest being derived from nonrenewable resources. By 1995, the consumption of renewable resources had declined dramatically, to only 8% of total consumption. During this century, the quantity of materials consumed has grown, from 161 million metric tons in 1900 to 2.8 billion metric tons by 1995, an equivalent of 10 metric tons per person per year. Of all the materials consumed during this century, more than half were consumed in the last 25 years. This paper examines the general historical shifts in materials consumption and presents an analysis of different measurements of materials use and the significance of their trends.

    2009-12-01

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

  3. Soil Materials and Health: An new experience for teaching

    2014-05-01

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

    Full Text Available Abstract The purpose of this study was to assess and determine impacts of insufficient instructional materials and ineffective lesson delivery methods on teaching in biology higher education. The participants of this study were 60 trainees who graduated in Bachelor of Sciences from eight public universities in majoring biology. Data for the study was collected while these trainees were attending the course of Biology Teaching Methods in the Post Graduate Diploma in Teaching, both in the regular and summer 2015/2016 training programs at Addis Ababa University. The study employs a mixed method design of both qualitative and quantitative data evaluations. Data was collected through classroom observations and interviews with the trainees. The findings indicated that insufficient instructional materials and ineffective teaching methods in higher education had negative impacts; that have affected the skills of performing biological tasks of graduates 71%. In the course of the Post Graduate Diploma in Teaching training, trainees were unsuccessful to conduct essential biological tasks expected from graduates of biology upon the completion of their undergraduate study program. The study was concluded with emphasis on the need to integrate theory and practice through using adequate instructional materials and proper teaching methods in the higher education biology teaching.

    The intensive care unit (ICU) is a dynamic and complex learning environment. The wide range in trainee's experience, specialty training, fluctuations in patient acuity and volume, limitations in trainee duty hours, and additional responsibilities of the faculty contribute to the challenge in providing a consistent experience with traditional educational strategies. The "flipped classroom" is an educational model with the potential to improve the learning environment. In this paradigm, students gain exposure to new material outside class and then use class time to assimilate the knowledge through problem-solving exercises or discussion. The rationale and pedagogical foundations for the flipped classroom are reviewed, practical considerations are discussed, and an example of successful implementation is provided. An education curriculum was devised and evaluated prospectively for teaching point-of-care echocardiography to residents rotating in the surgical ICU. Preintervention and postintervention scores of knowledge, confidence, perceived usefulness, and likelihood of use the skills improved for each module. The quality of the experience was rated highly for each of the sessions. The flipped classroom education curriculum has many advantages. This pilot study was well received, and learners showed improvement in all areas evaluated, across several demographic subgroups and self-identified learning styles.

    The Earth's bedrock is overlain in many places by a loosely compacted and mostly unconsolidated blanket of sediments in which soils commonly are developed. These sediments generally were eroded from underlying rock, and then were transported and deposited. In places, they exceed 1000 ft (330 m) in thickness. Where the sediment blanket is absent, bedrock is either exposed or has been weathered to produce a residual soil. For the conterminous United States, a map by Soller and Reheis (2004, scale 1:5,000,000; http://pubs.usgs.gov/of/2003/of03-275/) shows these sediments and the weathered, residual material; for ease of discussion, these are referred to as 'surficial materials'. That map was produced as a PDF file, from an Adobe Illustrator-formatted version of the provisional GIS database. The provisional GIS files were further processed without modifying the content of the published map, and are here published.

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

    2015-07-01

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

    2011-01-01

    Today's electronics packages are smaller and more powerful than ever before. This leads to ever increasing thermal challenges for the systems designer. The automotive electronic control unit (ECU) package faces the same challenge of thermal management as the industry in general. This is coupled with the latest European Union legislation (Euro 6 standard) which forced the ECU manufacturers to completely re-design their ECU platform with improved hardware and software capability. This will result in increased power densities and therefore, the ability to dissipate heat will be a key factor. A higher thermal conductivity (TC) material for the ECU housing (than the currently used Aluminium) could improve heat dissipation from the ECU. This paper critically reviews the state-of-the-art in thermal management materials which may be applicable to an automotive ECU. This review shows that of the different materials currently available, the Al/SiC composites in particular have very good potential for automotive ECU application. In terms of metal composites processing, the liquid metal infiltration process is recommended as it has a lower processing cost and it also has the ability to produce near net-shape materials.

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

    The transport of radioactive material forms a vital link in the nuclear fuel cycle in the United States. Actual U.S. experience and practice with such systems for the packaging and transport of uranium ore concentrates, uranium hexafluoride, fresh fuel, irradiated fuel, non-high-level waste, and plutonium with low heat generation rates are described. Specific shipping systems in current use for these services are illustrated. A comparison will be made of shipping requirements for nuclear parks versus dispersed facilities. Shipping systems for other fuel cycle materials (e.g., high-level waste and cladding hulls) have not been developed because there has been no need to transport these materials commercially. However, conceptual designs for packaging and transport of such materials have been developed. Selected systems are reviewed and summarized. Transport safety in the U.S. is regulated by the U.S. Department of Transportation and the Nuclear Regulatory Commission. Key regulations defining packaging requirements, allowable radiation dose rates, and handling procedures are reviewed. Although the radioactive material shipping industry has an outstanding safety record, opposition to nuclear fuel cycle shipments has surfaced in several areas. The U.S. congressional ban on the shipment of plutonium by air, the actions of New York City to prohibit certain shipments within the city limits, and the requirement of U.S. railroads to ship spent fuel casks only in dedicated trains are reviewed. In an attempt to provide information on the safety margins inherent in the design of radioactive materials packages, ERDA has undertaken a series of accident studies and full scale crash tests that stress the packages beyond the levels expected in severe accidents. In addition, the level of total risk associated with radioactive materials shipments is being evaluated. Current ERDA crash test and transportation risk assessment studies are reviewed.

    2016-02-01

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

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

    2014-09-01

    The Saltstone facilities at the DOE Savannah River Site (SRS) stabilize and dispose of low-level radioactive salt solution originating from liquid waste storage tanks at the site. The Saltstone Production Facility (SPF) receives treated salt solution and mixes the aqueous waste with dry cement, blast furnace slag, and fly ash to form a grout slurry which is mechanically pumped into concrete disposal cells that compose the Saltstone Disposal Facility (SDF). The solidified grout is termed “saltstone”. Cementitious materials play a prominent role in the design and long-term performance of the SDF. The saltstone grout exhibits low permeability and diffusivity, and thus represents a physical barrier to waste release. The waste form is also reducing, which creates a chemical barrier to waste release for certain key radionuclides, notably Tc-99. Similarly, the concrete shell of a saltstone disposal unit (SDU) represents an additional physical and chemical barrier to radionuclide release to the environment. Together the waste form and the SDU compose a robust containment structure at the time of facility closure. However, the physical and chemical state of cementitious materials will evolve over time through a variety of phenomena, leading to degraded barrier performance over Performance Assessment (PA) timescales of thousands to tens of thousands of years. Previous studies of cementitious material degradation in the context of low-level waste disposal have identified sulfate attack, carbonation influenced steel corrosion, and decalcification (primary constituent leaching) as the primary chemical degradation phenomena of most relevance to SRS exposure conditions. In this study, degradation time scales for each of these three degradation phenomena are estimated for saltstone and concrete associated with each SDU type under conservative, nominal, and best estimate assumptions.

  1. The Effectiveness of Scaffolding Design in Training Writing Skills Physics Teaching Materials

    Directory of Open Access Journals (Sweden)

    Parlindungan Sinaga

    2015-01-01

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

    2013-01-01

    The Saltstone facilities at the DOE Savannah River Site (SRS) stabilize and dispose of low-level radioactive salt solution originating from liquid waste storage tanks at the site. The Saltstone Production Facility (SPF) receives treated salt solution and mixes the aqueous waste with dry cement, blast furnace slag, and fly ash to form a grout slurry which is mechanically pumped into concrete disposal cells that compose the Saltstone Disposal Facility (SDF). The solidified grout is termed ''saltstone''. Cementitious materials play a prominent role in the design and long-term performance of the SDF. The saltstone grout exhibits low permeability and diffusivity, and thus represents a physical barrier to waste release. The waste form is also reducing, which creates a chemical barrier to waste release for certain key radionuclides, notably Tc-99. Similarly, the concrete shell of an SDF disposal unit (SDU) represents an additional physical and chemical barrier to radionuclide release to the environment. Together the waste form and the SDU compose a robust containment structure at the time of facility closure. However, the physical and chemical state of cementitious materials will evolve over time through a variety of phenomena, leading to degraded barrier performance over Performance Assessment (PA) timescales of thousands to tens of thousands of years. Previous studies of cementitious material degradation in the context of low-level waste disposal have identified sulfate attack, carbonation influenced steel corrosion, and decalcification (primary constituent leaching) as the primary chemical degradation phenomena of most relevance to SRS exposure conditions. In this study, degradation time scales for each of these three degradation phenomena are estimated for saltstone and concrete associated with each SDU type under conservative, nominal, and best estimate assumptions. The nominal value (NV) is an intermediate result that is more probable than the conservative estimate

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

    Iatrogenic pneumothorax is a patient safety indicator (PSI) representing a complication of procedures such as transthoracic needle aspiration, subclavicular needle stick, thoracentesis, transbronchial biopsy, pleural biopsy, and positive pressure ventilation. This study examined whether there was a significant difference in rate of iatrogenic pneumothorax in teaching hospitals compared to non-teaching hospitals from 2000 to 2012. We performed a retrospective cohort study on iatrogenic pneumothorax incidence from 2000 to 2012 using the Healthcare Cost and Utilization Project (HCUP) database. Pairwise t tests were performed. Odds ratios and P values were calculated, using a Bonferroni-adjusted α threshold, to examine differences in iatrogenic pneumothorax incidence in teaching vs. non-teaching hospitals. Our study revealed that after the year 2000, teaching hospitals had significantly greater iatrogenic pneumothorax incidence compared to non-teaching hospitals in every year of the study period (Ppneumothorax occurred with significantly greater incidence in teaching hospitals compared to non-teaching hospitals from 2000 to 2012. This trend may have been enhanced by the residency duty-hour regulations implemented in 2003 in teaching institutions, or due to higher rates of procedures in teaching institutions due to the nature of a tertiary center. Iatrogenic pneumothorax was more prevalent in teaching hospitals compared to non-teaching hospitals after the year 2000. Further randomized control studies are warranted to evaluate the etiology of this finding. Published by Elsevier Inc.

    The Department of Energy launched the Nuclear Materials Stewardship Initiative in January 2000 to accelerate the work of achieving integration and cutting long-term costs associated with the management of the Department's nuclear materials, with the principal focus on excess materials. Management of nuclear materials is a fundamental and enduring responsibility that is essential to meeting the Department's national security, nonproliferation, energy, science, and environmental missions into the distant future. The effective management of nuclear materials is important for a set of reasons: (1) some materials are vital to our national defense; (2) the materials pose physical and security risks; (3) managing them is costly; and (4) costs are likely to extend well into the future. The Department currently manages nuclear materials under eight programs, with offices in 36 different locations. Through the Nuclear Materials Stewardship Initiative, progress was during calendar year 20 00 in achieving better coordination and integration of nuclear materials management responsibilities and in evaluating opportunities to further coordinate and integrate cross-program responsibilities for the treatment, storage, and disposition of excess nuclear materials. During CY 2001 the Departmental approach to nuclear materials stewardship changed consistent with the business processes followed by the new administration. This paper reports on the progress of the Nuclear Materials Stewardship Initiative in evaluating and implementing these opportunities, and the remaining challenges in integrating the long-term management of nuclear materials

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

    Hayes, Margaret M; Chatterjee, Souvik; Schwartzstein, Richard M

    2017-04-01

    Critical thinking, the capacity to be deliberate about thinking, is increasingly the focus of undergraduate medical education, but is not commonly addressed in graduate medical education. Without critical thinking, physicians, and particularly residents, are prone to cognitive errors, which can lead to diagnostic errors, especially in a high-stakes environment such as the intensive care unit. Although challenging, critical thinking skills can be taught. At this time, there is a paucity of data to support an educational gold standard for teaching critical thinking, but we believe that five strategies, routed in cognitive theory and our personal teaching experiences, provide an effective framework to teach critical thinking in the intensive care unit. The five strategies are: make the thinking process explicit by helping learners understand that the brain uses two cognitive processes: type 1, an intuitive pattern-recognizing process, and type 2, an analytic process; discuss cognitive biases, such as premature closure, and teach residents to minimize biases by expressing uncertainty and keeping differentials broad; model and teach inductive reasoning by utilizing concept and mechanism maps and explicitly teach how this reasoning differs from the more commonly used hypothetico-deductive reasoning; use questions to stimulate critical thinking: "how" or "why" questions can be used to coach trainees and to uncover their thought processes; and assess and provide feedback on learner's critical thinking. We believe these five strategies provide practical approaches for teaching critical thinking in the intensive care unit.

    Full Text Available Nearly ten per cent of the students currently attending public schools in the United States are classified as English Language Learners (ELL; that is to say, students who are learning English. The most important challenge this population brings to the educational authorities of their school districts and the schools they attend, is to find the most effective ways to teach them both English and the academic content pertaining to their grade. Since the methods traditionally used did not teach them either the vocabulary or the content needed for subjects such as Math or Science, they fell behind their English-speaking peers. It was necessary, then, to evolve toward a better integration of the language and the lesson content. The present article summarizes the objectives of the traditional methods, details the changes that have taken place in the last decades to improve the simultaneous teaching of English and academic content, and concludes with an explanation of the techniques most used today.

    2017-09-01

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

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

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

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

    Effective communication is essential for shared decision making with families of critically ill patients in the intensive care unit (ICU), yet there is limited evidence on effective strategies to teach these skills. The study's objective was to pilot test an educational intervention to teach internal medicine interns skills in discussing goals of care and treatment decisions with families of critically ill patients using the shared decision making framework. The intervention consisted of a PowerPoint online module followed by a four-hour workshop implemented at a retreat for medicine interns training at an urban, academic medical center. Participants (N=33) completed post-intervention questionnaires that included self-assessed skills learned, an open-ended question on the most important learning points from the workshop, and retrospective pre- and post-workshop comfort level with ICU communication skills. Participants rated their satisfaction with the workshop. Twenty-nine interns (88%) completed the questionnaires. Important self-assessed communication skills learned reflect key components of shared decision making, which include assessing the family's understanding of the patient's condition (endorsed by 100%) and obtaining an understanding of the patient/family's perspectives, values, and goals (100%). Interns reported significant improvement in their comfort level with ICU communication skills (pre 3.26, post 3.73 on a five-point scale, p=0.004). Overall satisfaction with the intervention was high (mean 4.45 on a five-point scale). The findings suggest that a brief intervention designed to teach residents communication skills in conducting goals of care and treatment discussions in the ICU is feasible and can improve their comfort level with these conversations.

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

    1981-01-01

    A computer program, NUMATH (Nuclear Material Holdup Estimator), has been developed to permit inventory estimation in vessels involved in unit operations and chemical processes. This program has been implemented in an operating nuclear fuel processing plant. NUMATH's purpose is to provide steady-state composition estimates for material residing in process vessels until representative samples can be obtained and chemical analyses can be performed. Since these compositions are used for inventory estimation, the results are determined for and cataloged in container-oriented files. The estimated compositions represent material collected in applicable vessels-including consideration for material previously acknowledged in these vessels. The program utilizes process measurements and simple material balance models to estimate material holdups and distribution within unit operations. During simulated run testing, NUMATH-estimated inventories typically produced material balances within 7% of the associated measured material balances for uranium and within 16% of the associated, measured material balance for thorium during steady-state process operation

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

    2018-05-01

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

    1985-01-01

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

    1953-01-01

    Reconnaissance for radioactive materials was made in parts of Maine, New York, New Jersey, and Pennsylvania. The primary objective was to examine the iron ore deposits and associated rocks in the Adirondack Mountains of New York and the Highlands of New Jersey. In addition, several deposits known or reported to contain radioactive minerals were examined to delimit their extent. Most of the deposits examined are not significant as possible sources of radioactive elements and the data pertaining to them are summarized in table form. Deposits that do warrant more description than can be given in table form are: Benson Mines, St. Lawrence County, N. Y.; Rutgers mine, Clinton County, N. Y.; Mineville Mines, Essex County, N. Y.l Canfield phosphate mine, Morris County, N. J.; Mullgan quarry, Hunterdon County, N. J.; and the Chestnut Hill-Marble Mountain area, Pennsylvania and New Jersey. The Old Bed in the Mineville district is the only deposit that may be economically significant. Apatite from Old Bed ore contains as much as 4.9 percent total rare earth. 0.04 percent thorium, and 0.018 percent uranium. Magnetite ore at the Rutgers mine contains radioactive zircon and apatite. Radioactivity measurements of outcrops and dump material show that the ore contains from 0.005 to 0.010 percent equivalent uranium. One sample of lean magnetite ore contains 0.006 percent equivalent uranium. Garnet-rich zones in the Benson Mines magnetite deposit contain as much as 0.017 equivalent uranium. Most of the rock and ore, however, contains about 0.005 percent equivalent uranium. Available data indicate that the garnet-rich zones are enriched in radioactive allanite. A shear zone in the Kittatinny limestone of Cambrian age at the Mulligan quarry contains uraniferous material. Radioactivity anomalies elsewhere in the quarry and in adjacent fields indicate that there may be other uraniferous shear zones. Assays of samples and measurements of outcrop radioactivity indicate that the uranium

    2017-01-01

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

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

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

    Objective: To determine the prevalence and pattern of congenital malformations among neonates in a teaching hospital. Methods: The prospective hospital-based study was conducted over a period of 18 months in the neonatal unit of Combined Military Hospital, Kharian, from September 2011 to February 2013. All neonates from newborn to 28 days of age admitted to the unit irrespective of their condition comprised the study population. Neonatal examination was done by the Registrar at the time of admission followed by neonatologist/paediatrician. Information regarding gender, weight, gestational age, mode of delivery, consanguinity, maternal age, antenatal visit record and family history were recorded on a predesigned proforma. After clinical examination, if required, relevant investigations like ultrasonography, radiology, echocardiography, laboratory and genetic studies were done to confirm diagnosis. Data was statistically analysed by using SPSS 20. Results: Out of 3,210 total admissions, 226 (7%) neonates were congenitally malformed. Of them, 130 (57.52 %) were male and 96 (42.47 %) females. Among different body systems affected, anomalies related to the central nervous system were 46(20.35%) musculoskeletal 42(18.58%), genitourinary 34 (15.04%), cardiovascular system 30 (13.27%), ear, eye, face, neck 27(11.94%), digestive system 19 (8.40%), syndromes and skin 14 (6.19%) each. Conclusion: Congenital Malformations are not rare in our community and central nervous system is the most commonly affected system. Healthcare managers must stress upon primary prevention in the form of vaccination, nutrition and drugs to decrease preventable share of congenital malformations. (author)

    Full Text Available Background: Extrauterine growth restriction remains a common and serious problem in newborns especially who are small, immature, and critically ill. Very low birth weight infants (VLBW had 97% and 40% growth failure at 36 weeks and 18-22 months post-conceptual age respectively. The postnatal development of premature infants is critically dependent on an adequate nutritional intake that mimics a similar gestational stage. Deficient protein or amino acid administration over an extended period may cause significant growth delay or morbidity in VLBW infants. The purpose of this study was to evaluate current nutritional status in the neonatal intensive care unit in a teaching hospital. Methods: During this prospective observational study, the nutritional status of 100 consecutive critically ill neonates were evaluated by anthropometric and biochemical parameters in a tertiary neonatal intensive care unit. Their demographic characteristics (weight, height and head circumference, energy source (dextrose and lipid and protein were recorded in the first, 5th, 10th, 15th and 20th days of admission and blood samples were obtained to measure serum albumin and prealbumin. The amount of calorie and protein were calculated for all of preterm and term neonates and compared to standard means separately. Results: The calorie and amino acids did not meet in the majority of the preterm and term neonates and mean daily parenteral calorie intake was 30% or lower than daily requirements based on neonates’ weight. Mortality rate was significantly higher in neonates with lower serum albumin and severity of malnutrition but not with serum prealbumin concentration. Conclusion: Infants were studied did not receive their whole of daily calorie and protein requirements and it is recommended early and enough administration of calorie source (dextrose, lipids and amino acids. Prealbumin was a more benefit biochemical parameter than albumin to evaluate short term nutrition

    Full Text Available Physical inactivity is one of the most important problems that affect to our society due to the lack of student motivation in some school contents. The objective of this study was to study the relationship between motivational climate created by the Physical Education teacher in a teaching unit of rugby and basic psychological needs, self-determined motivation and affective consequences experienced by students. A total of 77 students (M age = 15.35, SD = 0.53 of an educational institution, belonging to 4th year Secondary Education, completed the following questionnaires: Perceived of Motivational Climate Scale (EPCM, Basic Psychological Needs in Excersice Scale (BPNES, Situational Motivation Scale (SIMS-14 and the Scale of Entertainment / Boredom in Physical Education (SSI-EF. The results showed that task climate predicted positively and significantly the three basic psychological needs and self-determined forms of motivation, while the ego climate predicted amotivation. In turn, the three basic psychological needs predicted positively intrinsic motivation, while the amotivation was negatively predicted by perceived competence and social relationships. Also, it was found a positive prediction between intrinsic motivation and enjoyment, and negatively with respect to boredom, which was also predicted by amotivation. The results suggest the idea that Physical Education teachers should create a task climate, favoring the satisfaction of the psychological mediators and developing a more self-determined motivation which could trigger affective consequences like enjoyment.

    Full Text Available The interpersonal style used by the teacher of Physical Education (PE in their classes can trigger consequences for students inside and outside the classroom. Grounded in self-determination theory and achievement goal theory, the aim of the study was to analyze the relationship between motivational climate and support of the basic psychological needs (BPN generated by the PE teacher in the teaching unit (TU of futsal, with consequences of enjoyment and boredom, as well as the predisposition toward EF experienced by students. The sample was composed of 70 students (32 men and 38 women year 4th of compulsory Secondary Education, aged 15 to 17 years (M age = 15.31, SD = 0.49. The variables measured at the end of the TU were: motivational climate (EPCM, support of the BPN (CANPB and affective consequences (SSI the content of futsal and the predisposition towards PE (PEPS. The results of correlation analysis showed that the task climate and support of the BPN in the TU futsal, correlated positively and significantly with enjoyment and some predisposing factors toward PE, while doing it in reverse with boredom. Therefore, given the relationship between what happens in the classroom and outside it, seems necessary that teachers of PE generates a task climate and support of the BPN in each of curricular content, to students adopt life-styles more active and healthy. 

  10. Using Evolution as a Context for Teaching the Nature of Science to Diverse Student Populations: A High School Unit of Curriculum

    Science.gov (United States)

    Metcalfe, Angela C.

    Teaching evolution provides teachers with the opportunity to educate students on how science aims to understand the natural world. Rooted in research, the purpose of this project was to create NGSS-aligned curriculum focused on teaching the nature of science (NOS) within the context of biological evolution. Field testing and review of the unit resulted in revisions aimed at creating more comprehensive teacher resource materials and explicit inclusion of NOS. Emphasizing NOS in curriculum development and teaching scientific qualities through an evolutionary context has taken the focus off belief or disbelief, keeping the attention on the scientific concept at hand. Designing curriculum around compelling subject matter and embracing student-led learning increased and maintained student interest in the classroom. Implementation of this curriculum not only requires the teacher to be knowledgeable in conventional educational pedagogy, but also the subjects of NGSS and NOS. Additional training and support centered around NGSS is recommended for science educators interested in integrating NOS into their curriculum and instruction.

    There is a paucity of literature evaluating the effects of family member presence during bedside medical rounds in the pediatric intensive care unit. We hypothesized that, when compared with rounds without family members, parental presence during morning medical rounds would increase time spent on rounds, decrease medical team teaching/education, increase staff dissatisfaction, create more stress in family members, and violate patient privacy in our open unit. Prospective, blinded, observational study. Academic pediatric intensive care unit with 12 beds. A total of 105 admissions were studied, 81 family members completed a survey, and 187 medical team staff surveys were completed. Investigators documented parental presence and time allocated for presentation, teaching, and answering questions. Surveys related to perception of goals, teaching, and privacy of rounds were distributed to participants. Time spent on rounds, time spent teaching on rounds, and medical staff and family perception of the effects of parental presence on rounds. There was no significant difference between time spent on rounds in the presence or absence of family members (p = NS). There is no significant difference between the time spent teaching by the attending physician in the presence or absence of family members (p = NS). Overall, parents reported that the medical team spent an appropriate amount of time discussing their child and were not upset by this discussion. Parents did not perceive that their own or their child's privacy was violated during rounds. The majority of medical team members reported that the presence of family on rounds was beneficial. Parental presence on rounds does not seem to interfere with the educational and communication process. Parents report satisfaction with participation in rounds, and privacy violations do not seem to be a concern from their perspective.

    Full Text Available In this article the results of the analysis of free and concept maps produced are presented from the application and evaluation of a Potentially Meaningful Teaching Units – PMTU, which is a teaching sequence based on various learning theories and seeks to promote meaningful student learning. Presents, in this work, part of a research Masters in Science Education which deals with the inclusion of topics of particle physics integrated with traditional content of the third year of high school. It was implemented in a third grade high school class of a State School in Santa Maria, Rio Grande do Sul, and Brazil. The PMTU aimed to address in an integrated manner threads for Particle Physics and Electronics. A didactic sequence that integrated the topics of electric charge, atomic models, elementary particles, quantization and process electrification was applied. Such integration aimed at stimulating the interest on topics related to Modern and Contemporary Physics. It was developed using PMTU activities that aimed at promoting meaningful learning and knowledge construction in the classroom, Since the topics involved were quite complex, this made their integration a real challenge to the high school teachers, and resulted in changes in their teaching practices. Research showed that the inclusion of topics on physics of elementary particles the and electricity, through Potentially Meaningful Teaching Units, show satisfactory results in the students’ learning.

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

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

    Full Text Available This work paper shows research results on the contextualized dynamics of the constant shaping of advisor professors in the teaching unit, taking epistemological foundations as a starting point, which substantiate their theoretical construction. A model has been displayed basing on comprehension and interpretation of this process as a whole, in which its subsystems, components, structure, relations and levels among them, prove contradictions that become evident in such process, therefore allowing to structure the dynamics of shaping professors as an instrument, earning, as a result, the transforming capability of advisor professors when practicing their skill, having the teaching unit as a scenary. In that way we used different techniques: questionnaire, interviews, observation, statistical techniques and methods: historical-logical; analysis-synthesis and systemic-structural-functional, all of those ones from the hermeneutic-dialectic focus.

    1982-01-01

    A computer program, PREMATH (Precious Material Holdup Estimator), has been developed to permit inventory estimation in vessels involved in unit operations and chemical processes. This program has been implemented in an operating nuclear fuel processing plant. PREMATH's purpose is to provide steady-state composition estimates for material residing in process vessels until representative samples can be obtained and chemical analyses can be performed. Since these compositions are used for inventory estimation, the results are determined for and cataloged in container-oriented files. The estimated compositions represent material collected in applicable vessels - including consideration for material previously acknowledged in these vessels. The program utilizes process measurements and simple material balance models to estimate material holdups and distribution within unit operations. During simulated run testing, PREMATH-estimated inventories typically produced material balances within 7% of the associated measured material balances for uranium and within 16% of the associated, measured material balances for thorium (a less valuable material than uranium) during steady-state process operation

    This paper discusses the requirements and issues associated with the transportation of surplus fissile materials in the United States. The paper describes the materials that will be transported, the permissible modes of transport for these materials, and the safety and security requirements for each mode of transport. The paper also identifies transportation issues associated with these requirements, including the differences in requirements corresponding to who owns the material and whether the transport is on-site or off-site. Finally, the paper provides a discussion that suggests that by adopting the spent fuel standard and stored weapon standard proposed by the National Academy of Sciences, the requirements for transportation become straightforward

    The Secretary of Energy of the United States, Spencer Abraham, Minister of the Russian Federation on Atomic Energy, Alexander Rumyantsev, and Director General of the International Atomic Energy Agency (IAEA), Mohamed ElBaradei, met in Vienna on 18 September 2001 to review progress on the Trilateral Initiative. The Initiative was launched in 1996 to develop a new IAEA verification system for weapon-origin material designated by the United States and the Russian Federation as released from their defence programmes. The removal of weapon-origin fissile material from the defence programmes of the Russian Federation and the United States is in furtherance of the commitment to disarmament undertaken by the two States pursuant to Article VI of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). IAEA verification under this Initiative is intended to promote international confidence that fissile material made subject by either of the two States to Agency verification remains irreversibly removed from nuclear weapon programmes

    2017-08-22

    The economic growth of an industrialized nation such as the United States requires raw materials for construction (buildings, bridges, highways, and so forth), defense, and processing and manufacture of goods and services. Since the beginning of the 20th century, the types and quantities of raw materials used have increased and changed significantly. This fact sheet quantifies the amounts of raw materials (other than food and fuel) that have been used in the U.S. economy annually for a period of 115 years, from 1900 through 2014. It provides a broad overview of the quantity (weight) of nonfood and nonfuel materials used in the economy and illustrates the use and significance of raw nonfuel minerals in particular as building blocks of society.These data have been compiled to help the public and policymakers understand the changing annual flow of raw materials put into use in the United States. Such information can be helpful in assessing the potential effects of materials use on the environment, assessing materials’ intensity of use, and examining the role that these materials play in the economy. The data presented indicate the substitution and shift in materials usage from renewable to nonrenewable materials during the 20th century. The disaggregated quantities by commodity (not shown in this fact sheet) may be tested against supply adequacy and end of life issues.

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

    International Nuclear Information System (INIS)

    Huebel, Horst

    2010-01-01

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

    1996-09-01

    Several direct coal liquefaction processes have been demonstrated at the pilot plant level in the United States. Presently only one plant remains operational, namely, the Hydrocarbon Technologies, Inc., 4.0- ton-per-day process development unit in Lawrenceville, New Jersey. The period from 1974 to 1982 saw the greatest amount of development of direct coal liquefaction in the United States with four major pilot plants being devoted to variants of this technology. The plants included the SRC-I plant at Wilsonville, Alabama, which operated from 1974 to 1992; the SRC-I/II plant at Fort Lewis, Washington, which operated from 1974 to 1981; the H-Coal plant at Catlettsburg, Kentucky, which operated from 1980 to 1982; and the Exxon Coal Liquefaction Pilot Plant at Baytown, Texas, which operated from 1980 to 1982. Oak Ridge National Laboratory scientists and engineers were actively involved in many phases and technical disciplines at all four of these plants, especially in materials testing, evaluation, and failure analyses. In addition, ORNL materials scientists and engineers conducted reviews of the demonstration and commercial plant designs for materials selections. The ORNL staff members worked closely with materials engineers at the pilot plants in identifying causes of materials degradation and failures, and in identifying solutions to these problems. This report provides a comprehensive summary of those materials activities. Materials performance data from laboratory and coal liquefaction pilot plant tests, failure analyses, and analyses of components after use in pilot plants were reviewed and assessed to determine the extent and causes of materials degradation in direct coal liquefaction process environments. Reviews of demonstration and commercial plant design documents for materials selections were conducted. These reviews and assessments are presented to capture the knowledge base on the most likely materials of construction for direct coal liquefaction plants.

    The last aim of this educational experience is the increase of the motivation of the students for the learning of the matters to giving as well as looking for the raising awareness, placing in the center the student and distinguishing the teaching for every group and specific case with different action plans for subjects and groups. This aim happens for achieving a major participation of the students in the way of developing and raising the matters (active subjects in the teaching), with a major follow-up of the teacher and a constant feedback with possibility of change in the exposition of the subjects to mold it to the characteristics of the groups of students. Besides the previous thing, one tries to obtain a manual of good practices in the classroom as well as a compendium of the actions undertaken before mistakes or aspects identified in the classroom and what results they have served us as tools for future or current teachers. Likewise, also one tries to improve the implantation of the systems of follow-up of the quality and also of coordination of professorship in the subject of Materials Science. The accomplishment of the questionnaires carried out by means of the controls of personalized response Educlick, equipment that was obtained by a Project of Educational Investigation (University of Salamanca), and that provides an experience of participation to the students. As for the teachers, it allows the application of measures of improvement and implementation of the qualit systems. It might extend to other Powers and Centers that are interested in similar experiences. The feedback has distinguished himself as one of the most powerful tools for the learning (Black and Williams, 1998). The investigation-action in the classroom (Avison et to, 1999; Contreras Perez and Arbesú García, 2008; Samian and Noor, 2012) supposes a methodology that allows to modify in time the teaching and to contribute this feedback to the pupils in every moment.

    In pediatric teaching hospitals, medical decisions are traditionally made by the attending and resident physicians during rounds that do not include parents. This structure limits the ability of the medical team to provide "family-centered care" and the attending physician to model communication skills. The authors thus set out to identify how parents responded to participation in interdisciplinary teaching rounds conducted in a large tertiary care children's teaching hospital. A qualitative descriptive study was conducted using data from semistructured interviews of parents who had participated in rounds on the inpatient medical unit of a large academic children's hospital. From December 2004 to April 2005, 18 parents were interviewed after their participation in rounds. Questions assessed their experiences, expectations, preferred communication styles, and suggestions for improvement. Transcripts of the interviews were analyzed using qualitative content analysis. Being able to communicate, understand the plan, and participate with the team in decision making about their child's care were the most frequently cited outcomes of importance to parents. All 18 participants described the overall experience as positive, and 17 of 18 described themselves as "comfortable" with inclusion in rounds. Use of lay terminology and inclusion of nurses in rounds were preferred. Including parents on ward rounds at a teaching hospital was viewed positively by parents. Specific themes of particular importance to parents were identified. Further study is needed to assess the impact of inclusion of parents on rounds on patient outcomes and the resident experience.

    Full Text Available Aim: The aim of this study was to evaluate the effect of indirect restorative materials (IRMs and light-curing units (LCUs on the micro hardness of dual-cured resin cement. Materials and Methods: A total of 36 cylindrical samples (2 mm thick were prepared with dual-cured resin cement (Relyx ARC photo-activated with either a QTH (Optilight Plus for 40s or a LED (Radii light-curing unit for 65s. Photo-activation was performed through the 2-mm- thick IRMs and the samples were divided into six groups (n=6 according to the combination of veneering materials (without, ceramic and indirect resin and LCUs (QTH and LED. In the control group, the samples were light-cured with a QTH unit without the interposition of any restorative material. Vickers micro hardness test was performed on the top and bottom surfaces of each sample (load of 50 g for 15 secs. The data were statistically analyzed using a three-way ANOVA followed by Tukey x s post-hoc test ( P < 0.05. Results: There were no statistically significant differences on the top surface between the light curing-units ( P > 0.05; however, the LED provided greater hardness on the bottom surface when a ceramic material was used ( P < 0.05. The mean hardness in photo-activated samples, in which there was no interposition of indirect materials, was significantly greater ( P < 0.01. Conclusions: It may be concluded that the interposition of the restorative material decreased the micro hardness in the deeper cement layer. Such decrease, however, was lower when the ceramic was interposed and the cement light-cured with LED.

    1987-05-21

    The invention refers to a process for the gasification of solid and combustible material in a moving bed and a unit in which this process can be carried out. By material to be gasified one means small material such as ground fossil coal and all organic substances such as wood, straw, husks and shells of fruit, to which sewage sludge can be added. The new process can be carried out, according to the invention, in a closed duct moved by vibration or shaking, in which the material or the ash produced moves from one end to the other by suitable vibration and comes into contact with round heat sources largely resistant to friction. This achieves rapid gasification of the material (at about 1000/sup 0/C) by convection and radiation.

    Full Text Available This study qualitatively analyzes the culture conflicts professors in the United States and Mexico are experiencing with the increasing pressures to produce more research about higher education. The first dataset was collected from 36 faculty members from 12 small and medium sized private, doctorate-granting universities. These universities are located in 11 states across the United States. The remaining data came from 44 faculty members employed at four small and medium sized private, doctoral granting universities in four states across Mexico. Results showed that universities in the US are transitioning from a predominantly teaching college culture to a more research orientation. Although the sampled universities continue to offer established graduate programs, faculty members continue to struggle with their teaching requirements and conflicts research productivity pressures place on their teaching and mentoring time with students. Participating faculty members employed in the US were not evenly interested in research opportunities due to the diverse mission objectives promoted by their respective institutions. On the other hand, faculty members employed in Mexico were generally more concerned with their research productivity and subsequent factors, which negatively impact their research productivity. Mexican faculty members rarely cited conflicts between their institutional missions and teaching objectives. This study is highly relevant to policy makers, higher education administrators, and scholars interested in comparative and international higher education. Administrators can benefit from the findings in this study, which provides faculty members’ perceptions and describes departmental structures and organizational dynamics employed to advance greater research and development opportunities. This study concludes with a discussion on how administrators and faculty members should handle the pressures for research productivity and

    2015-04-01

    Full Text Available Abstract Global research has shown the persistence of inequality with regard to accessing curriculum with a view to obtaining suitable work and making useful contributions to society. The intersection of race, gender, language and low socio-economic levels creates situations which often marginalize ethnic minorities in school settings (Freire, 1968; Nieto & Turner, 2012. The graduation rates in the United States for Native American, African American and Hispanic students are lower than the graduation rates of Whites and Asian Americans. In addition, Bangladeshis and African Caribbeans currently living in the UK are under-represented in higher education, particularly young men in those communities. The research questions that guide this inquiry are: (1 According to databases, how does the academic performance of language minority groups compare to the academic performance of non-linguistic minority groups at the elementary and secondary levels of education? (2 According to language support teachers and university students, what are the strengths and weaknesses of the instructional practices for language minorities who are learning English in the United Kingdom (UK (Bristol and the United States (US (Henrico? Participants were: five UK teachers, four UK university students, five US teachers, four US university students. Data collection supervised by lead researchers included interviews, focus groups, classroom observation, and performance documents. Data analysis utilized a mixed-methods approach. Overall, linguistic minority groups performed lower than their English proficient peers. Culturally, UK teachers provided a greater emphasis on religious instruction, whereas US teachers addressed patriotic topics more frequently. Teachers in the United States and the United Kingdom were culturally supportive with slight variation in the encouraged use of the students’ heritage languages.

  16. The distribution of common construction materials at risk to acid deposition in the United States

    Science.gov (United States)

    Lipfert, Frederick W.; Daum, Mary L.

    Information on the geographic distribution of various types of exposed materials is required to estimate the economic costs of damage to construction materials from acid deposition. This paper focuses on the identification, evaluation and interpretation of data describing the distributions of exterior construction materials, primarily in the United States. This information could provide guidance on how data needed for future economic assessments might be acquired in the most cost-effective ways. Materials distribution surveys from 16 cities in the U.S. and Canada and five related databases from government agencies and trade organizations were examined. Data on residential buildings are more commonly available than on nonresidential buildings; little geographically resolved information on distributions of materials in infrastructure was found. Survey results generally agree with the appropriate ancillary databases, but the usefulness of the databases is often limited by their coarse spatial resolution. Information on those materials which are most sensitive to acid deposition is especially scarce. Since a comprehensive error analysis has never been performed on the data required for an economic assessment, it is not possible to specify the corresponding detailed requirements for data on the distributions of materials.

  17. Unit-Sphere Multiaxial Stochastic-Strength Model Applied to Anisotropic and Composite Materials

    Science.gov (United States)

    Nemeth, Noel, N.

    2013-01-01

    Models that predict the failure probability of brittle materials under multiaxial loading have been developed by authors such as Batdorf, Evans, and Matsuo. These "unit-sphere" models assume that the strength-controlling flaws are randomly oriented, noninteracting planar microcracks of specified geometry but of variable size. This methodology has been extended to predict the multiaxial strength response of transversely isotropic brittle materials, including polymer matrix composites (PMCs), by considering (1) flaw-orientation anisotropy, whereby a preexisting microcrack has a higher likelihood of being oriented in one direction over another direction, and (2) critical strength, or K (sub Ic) orientation anisotropy, whereby the level of critical strength or fracture toughness for mode I crack propagation, K (sub Ic), changes with regard to the orientation of the microstructure. In this report, results from finite element analysis of a fiber-reinforced-matrix unit cell were used with the unit-sphere model to predict the biaxial strength response of a unidirectional PMC previously reported from the World-Wide Failure Exercise. Results for nuclear-grade graphite materials under biaxial loading are also shown for comparison. This effort was successful in predicting the multiaxial strength response for the chosen problems. Findings regarding stress-state interactions and failure modes also are provided.

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

    Coronary artery disease is prevalent in China, with concomitant increases in the volume of coronary artery bypass grafting (CABG). The present study aims to compare CABG-related outcomes between China and the United States among large teaching and urban hospitals. Observational analysis of patients aged ≥18 years, discharged from acute-care, large teaching and urban hospitals in China and the United States after hospitalization for an isolated CABG surgery. Data were obtained from the Chinese Cardiac Surgery Registry in China and the National Inpatient Sample in the United States. Analysis was stratified by 2 periods: 2007, 2008, and 2010; and 2011 to 2013 periods. The primary outcome was in-hospital mortality, and the secondary outcome was length of stay. The sample included 51 408 patients: 32 040 from 77 hospitals in the China-CABG group and 19 368 from 303 hospitals in the US-CABG group. In the 2007 to 2008, 2010 period and for all-age and aged ≥65 years, the China-CABG group had higher mortality than the US-CABG group (1.91% versus 1.58%, P =0.059; and 3.12% versus 2.20%, P =0.004) and significantly higher age-, sex-, and comorbidity-adjusted odds of death (odds ratio, 1.58; 95% confidential interval, 1.22-2.04; and odds ratio, 1.73; 95% confidential interval, 1.24-2.40). There were no significant mortality differences in the 2011 to 2013 period. For preoperative, postoperative, and total hospital stay, respectively, the median (interquartile range) length of stay across the entire study period between China-CABG and US-CABG groups were 9 (8) versus 1 (3), 9 (6) versus 6 (3), and 20 (12) versus 7 (5) days (all P China and the United States.

    2009-10-01

    While astrobiology is apparently growing steadily around the world, in terms of the number of researchers drawn into this interdisciplinary area and teaching courses provided for new students, there have been very few studies conducted to chart this expansion quantitatively. To address this deficiency, the Astrobiology Society of Britain (ASB) conducted a questionnaire survey of universities and research institutions nationwide to ascertain the current extent of astrobiology research and teaching in the UK. The aim was to provide compiled statistics and an information resource for those who seek research groups or courses of study, and to facilitate new interdisciplinary collaborations. The report here summarizes details gathered on 33 UK research groups, which involved 286 researchers (from undergraduate project students to faculty members). The survey indicates that around 880 students are taking university-level courses, with significant elements of astrobiology included, every year in the UK. Data are also presented on the composition of astrobiology students by their original academic field, which show a significant dominance of physics and astronomy students. This survey represents the first published systematic national assessment of astrobiological academic activity and indicates that this emerging field has already achieved a strong degree of penetration into the UK academic community.

    1979-01-01

    The Nuclear Regulatory Commission is considering the use of maximum-loss performance criteria as a means of controlling SNM in nuclear plants. The Controllable Unit Approach to material control and accounting (CUA) was developed by Mound to determine the feasibility of controlling a plant to a performance criterion. The concept was tested with the proposed Anderson, SC, mixed-oxide plant, and it was shown that CUA is indeed a feasible method for controlling a complex process to a performance criterion. The application of CUA to an actual low-enrichment plant to assist the NRC in establishing performance criteria for uranium processes is discussed. 5 refs

    Full text: Russian Federation Minister of Atomic Energy Alexander Rumyantsev, United States Secretary of Energy Spencer Abraham and Director General of the International Atomic Energy Agency (IAEA) Mohamed ElBaradei met in Vienna on 16 September 2002 to review the status of the Trilateral Initiative and agree on its future direction. The parties concluded that the task entrusted to the Trilateral Initiative Working Group in 1996 has been fulfilled. The work completed has demonstrated practical approaches for IAEA verification of weapon-origin fissile material designated as released from defence programmes in classified forms or at certain sensitive facilities. The work included the examination of technical, legal and financial issues associated with such verification. The removal of weapon-origin fissile material from defence programmes of the Russian Federation and the United States is in furtherance of the commitment to disarmament steps undertaken by the two States pursuant to Article VI of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). IAEA verification of the materials declared excess to nuclear weapons programmes and made subject to this Initiative would build international confidence that this material will never again be used in nuclear weapons. Minister Rumyantsev, Secretary Abraham and Director General ElBaradei recognized the value of the groundbreaking work completed over the last six years. Building on the work completed, they directed the technical experts to begin without delay discussions on future possible cooperation within the trilateral format. Minister Rumyantsev, Secretary Abraham and Director General ElBaradei agreed that the Principals would meet again in September 2003 to review progress within the trilateral format. (IAEA)

    Waldstein, S R; Neumann, S A; Drossman, D A; Novack, D H

    2001-01-01

    A survey of US medical schools regarding the incorporation of psychosomatic (biopsychosocial) medicine topics into medical school curriculum was conducted. The perceived importance and success of this curriculum, barriers to teaching psychosomatic medicine, and curricular needs were also assessed. From August 1997 to August 1999, representatives of US medical schools were contacted to complete a survey instrument either by telephone interview or by written questionnaire. Survey responses were received from 54 of the 118 US medical schools contacted (46%). Responses were obtained from representatives of both public (57%) and private (43%) institutions. Only 20% of respondents indicated that their schools used the term "psychosomatic medicine"; the terms "behavioral medicine" (63%) and "biopsychosocial medicine" (41%) were used more frequently. Coverage of various health habits (eg, substance use and exercise) ranged from 52% to 96%. The conceptualization and/or measurement of psychosocial factors (eg, stress and social support) was taught by 80% to 93% of schools. Teaching about the role of psychosocial factors in specific disease states or syndromes ranged from 33% (renal disease) to 83% (cardiovascular disease). Coverage of treatment-related issues ranged from 44% (relaxation/biofeedback) to 98% (doctor-patient communication). Topics in psychosomatic medicine were estimated to comprise approximately 10% (median response) of the medical school curriculum. On a scale of 1 (lowest) to 10 (highest), ratings of the relative importance of this curriculum averaged 7 (SD = 2.5; range = 2-10). Student response to the curriculum varied from positive to mixed to negative. Perceived barriers to teaching psychosomatic medicine included limited resources (eg, time, money, and faculty), student and faculty resistance, and a lack of continuity among courses. Sixty-three percent of respondents expressed an interest in receiving information about further incorporation of topics in

  16. Mapping watershed potential to contribute phosphorus from geologic materials to receiving streams, southeastern United States

    Terziotti, Silvia; Hoos, Anne B.; Harned, Douglas; Garcia, Ana Maria

    2010-01-01

    As part of the southeastern United States SPARROW (SPAtially Referenced Regressions On Watershed attributes) water-quality model implementation, the U.S. Geological Survey created a dataset to characterize the contribution of phosphorus to streams from weathering and erosion of surficial geologic materials. SPARROW provides estimates of total nitrogen and phosphorus loads in surface waters from point and nonpoint sources. The characterization of the contribution of phosphorus from geologic materials is important to help separate the effects of natural or background sources of phosphorus from anthropogenic sources of phosphorus, such as municipal wastewater or agricultural practices. The potential of a watershed to contribute phosphorus from naturally occurring geologic materials to streams was characterized by using geochemical data from bed-sediment samples collected from first-order streams in relatively undisturbed watersheds as part of the multiyear U.S. Geological Survey National Geochemical Survey. The spatial pattern of bed-sediment phosphorus concentration is offered as a tool to represent the best available information at the regional scale. One issue may weaken the use of bed-sediment phosphorus concentration as a surrogate for the potential for geologic materials in the watershed to contribute to instream levels of phosphorus-an unknown part of the variability in bed-sediment phosphorus concentration may be due to the rates of net deposition and processing of phosphorus in the streambed rather than to variability in the potential of the watershed's geologic materials to contribute phosphorus to the stream. Two additional datasets were created to represent the potential of a watershed to contribute phosphorus from geologic materials disturbed by mining activities from active mines and inactive mines.

    2012-08-01

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

  1. The materials flow of mercury in the economies of the United States and the world

    Science.gov (United States)

    Sznopek, John L.; Goonan, Thomas G.

    2000-01-01

    Although natural sources of mercury exist in the environment, measured data and modeling results indicate that the amount of mercury released into the biosphere has increased since the beginning of the industrial age. Mercury is naturally distributed in the air, water, and soil in minute amounts, and can be mobile within and between these media. Because of these properties and the subsequent impacts on human health, mercury was selected for an initial materials flow study, focusing on the United States in 1990. This study was initiated to provide a current domestic and international analysis. As part of an increased emphasis on materials flow, this report researched changes and identified the associated trends in mercury flows; it also updates statistics through 1996. In addition to domestic flows, the report includes an international section, because all primary mercury-producing mines are currently foreign, 86 percent of the mercury cell sector of the worldwide chlor-alkali industry is outside the United States, there is a large international mercury trade (1,395 t 1 in 1996), and environmental regulations are not uniform or similarly enforced from country to country. Environmental concerns have brought about numerous regulations that have dramatically decreased both the use and the production of mercury since the late 1980?s. Our study indicates that this trend is likely to continue into the future, as the world eliminates the large mercury inventories that have been stockpiled to support prior industrial processes and products.

    Waqas, Adeel; Ali, Majid; Ud Din, Zia

    2017-04-01

    Utilisation of solar energy and the night ambient (cool) temperatures are the passive ways of heating and cooling of buildings. Intermittent and time-dependent nature of these sources makes thermal energy storage vital for efficient and continuous operation of these heating and cooling techniques. Latent heat thermal energy storage by phase-change materials (PCMs) is preferred over other storage techniques due to its high-energy storage density and isothermal storage process. The current study was aimed to evaluate the performance of the air-based PCM storage unit utilising solar energy and cool ambient night temperatures for comfort heating and cooling of a building in dry-cold and dry-hot climates. The performance of the studied PCM storage unit was maximised when the melting point of the PCM was ∼29°C in summer and 21°C during winter season. The appropriate melting point was ∼27.5°C for all-the-year-round performance. At lower melting points than 27.5°C, declination in the cooling capacity of the storage unit was more profound as compared to the improvement in the heating capacity. Also, it was concluded that the melting point of the PCM that provided maximum cooling during summer season could be used for winter heating also but not vice versa.

  9. Changing patterns in the use, recycling, and material substitution of mercury in the United States

    Science.gov (United States)

    Wilburn, David R.

    2013-01-01

    Environmental concerns have led to numerous regulations that have dramatically decreased the reported production and use of mercury in the United States since the 1980s. Government legislation and subsequent industry actions have led to increased collection of mercury-containing materials and the recovery of mercury through recycling. Mercury emissions have been reduced and effective alternatives to mercury products have been developed for many applications. This study updates and quantifies the changes in demand, supply, use, and material flow for mercury in various sectors in the United States that have taken place since 1996. Nearly all primary mercury produced in the United States is derived as a byproduct of processing of gold and silver ore in Nevada. Since 2001, annual production of mercury from gold and silver mining in Nevada has decreased by 22 percent overall because ore from greater depths containing low grade mercury is recovered, and mercury emissions from this source have decreased by 95 percent as a result of increased regulation and improved collection and suppression technology. The distribution of consumption of mercury in the United States has changed as a result of regulation (elimination of large-scale mercury use in the paint and battery sectors), reduction by consumers (decommissioning of mercury-cell chloralkali manufacturing capacity), and technological advances (improvements in dental, lighting, and wiring sectors). Mercury use in the chloralkali sector, the leading end-use sector in the United States in 1996, has declined by 98 percent from 136 metric tons (t) in 1996 to about 0.3 t in 2010 because of increased processing and recycling efficiencies and plant closures or conversion to other technologies. As plants were closed, mercury recovered from the infrastructure of decommissioned plants has been exported, making the United States a net exporter of mercury, even though no mercury has been produced as the primary product from mines in

    2012-05-08

    We have developed a high-throughput graphics processing units (GPU) code that can characterize a large database of crystalline porous materials. In our algorithm, the GPU is utilized to accelerate energy grid calculations where the grid values represent interactions (i.e., Lennard-Jones + Coulomb potentials) between gas molecules (i.e., CH$_{4}$ and CO$_{2}$) and material's framework atoms. Using a parallel flood fill CPU algorithm, inaccessible regions inside the framework structures are identified and blocked based on their energy profiles. Finally, we compute the Henry coefficients and heats of adsorption through statistical Widom insertion Monte Carlo moves in the domain restricted to the accessible space. The code offers significant speedup over a single core CPU code and allows us to characterize a set of porous materials at least an order of magnitude larger than ones considered in earlier studies. For structures selected from such a prescreening algorithm, full adsorption isotherms can be calculated by conducting multiple grand canonical Monte Carlo simulations concurrently within the GPU.

    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.

    2004-06-01

    The objective was to develop a web-based, virtual series of lectures for evidence-based, standardized knowledge transfer independent of location and time with possibilities for interactive participation and a concluding web-based online examination. Within the framework of a research project, specific Intranet and Internet capable course modules were developed together with a concluding examination. The concept of integrating digital and analogue course units supported by sound was based on FlashCam (Nexus Concepts), Flash MX (Macromedia), HTML and JavaScript. A Web server/SGI Indigo Unix server was used as a platform by the course provider. A variety of independent formats (swf, avi, mpeg, DivX, etc.) were integrated in the individual swf modules. An online examination was developed to monitor the learning effect. The examination papers are automatically forwarded by email after completion. The results are also returned to the user automatically after they have been processed by a key program and an evaluation program. The system requirements for the user PC have deliberately been kept low (Internet Explorer 5.0, Flash-Player 6, 56 kbit/s modem, 200 MHz PC). Navigation is intuitive. Users were provided with a technical online introduction and a FAQ list. Eighty-two students of dentistry in their 3rd to 5th years of study completed a questionnaire to assess the course content and the user friendliness (SPSS V11) with grades 1 to 6 (1 = 'excellent' and 6 = 'unsatisfactory'). The course units can be viewed under the URL: http://giga.rrze.uni-erlangen.de/movies/MKG/trailer and URL: http://giga.rrze.uni-erlangen.de/movies/MKG/demo/index. Some 89% of the students gave grades 1 (excellent) and 2 (good) for accessibility independent of time and 83% for access independent of location. Grades 1 and 2 were allocated for an objectivization of the knowledge transfer by 67% of the students and for the use of video sequences for demonstrating surgical techniques by 91% of the

    ; according to the experience from the old design no major problems are expected concerning stress levels and gap formation in the pebble beds; in fact, the situation should be more favourable due to the reduced dimensions (max. 20 cm) of the beds that should minimise ratcheting and particle flow phenomena. In respect to tritium extraction, the most favourable features of the HCPB concept (e.g. an overall low partial pressure of tritium in the beds that minimise permeation into the main coolant system) can be kept in the new design; a complication could be the necessity to provide each cell with a system of tubes to inlet the purge helium in the front part of the beds or to divide the purge flow for Be and CB. The modular design of the new HCPB blanket, that makes the breeder units almost independent on the structural design of the box, opens interesting possibilities in the development of these units. The present design can be optimised on the basis of the results of the present R and D programme on Be and CB. In addition, new requirements could appear to improve the design performances or manufacturing: i.e. in respect to filling procedures of the beds (use of pre-packed breeder units) or the necessity of insulating layer to thermally decouple the breeder units from the box or the selection of new materials with a better compatibility with Be and CB at high temperatures as protection of the steel structure.

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

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

    Covalent organic frameworks (COFs) having periodicity in pores of nanoscale dimensions can be suitably designed for the organic building units bearing reactive functional groups at their surfaces. Thus, they are an attractive option as an anticancer agent to overcome the limitations of chemotherapy. Herein, we first report a new porous biodegradable nitrogen containing COF material, EDTFP-1 (ethylenedianiline-triformyl phloroglucinol), synthesized using 4,4'-ethylenedianiline and 2,4,6-triformylphloroglucinol via Schiff base condensation reaction. EDTFP-1 exhibited 3D-hexagonal porous structure with average pores of ca. 1.5 nm dimension. Here, we have explored the anti-cancer potentiality of EDTFP-1. Result demonstrated an enhanced cytotoxicity was observed against four cancer cells HCT 116, HepG2, A549, and MIA-Paca2 with significant lower IC50 on HCT116 cells. Additionally, EDTFP-1-induced cell death was associated with the characteristic apoptotic changes like cell membrane blebbing, nuclear DNA fragmentation, externalization of phosphatidylserine from the cell membrane followed by a loss of mitochondrial membrane potential as well as modulation of pro and anti-apoptotic proteins. Further, the result depicted a direct correlation between the generations of ROS with mitochondrial-dependant apoptosis through the involvement of p53 phosphorylation upon EDTFP-1 induction, suggesting this COF material is a novel chemotherapeutic agent for cancer treatment.

    Full Text Available Infections caused by bacteria of genus Acinetobacter pose a significant health care challenge worldwide. Information on molecular epidemiological investigation of outbreaks caused by Acinetobacter species in Kosova is lacking. The present investigation was carried out to enlight molecular epidemiology of Acinetobacterbaumannii in the Central Intensive Care Unit (CICU of a University hospital in Kosova using pulse field gel electrophoresis (PFGE. During March - July 2006, A. baumannii was isolated from 30 patients, of whom 22 were infected and 8 were colonised. Twenty patients had ventilator-associated pneumonia, one patient had meningitis, and two had coinfection with bloodstream infection and surgical site infection. The most common diagnoses upon admission to the ICU were politrauma and cerebral hemorrhage. Bacterial isolates were most frequently recovered from endotracheal aspirate (86.7%. First isolation occurred, on average, on day 8 following admission (range 1-26 days. Genotype analysis of A. baumannii isolates identified nine distinct PFGE patterns, with predominance of PFGE clone E represented by isolates from 9 patients. Eight strains were resistant to carbapenems. The genetic relatedness of Acinetobacter baumannii was high, indicating cross-transmission within the ICU setting. These results emphasize the need for measures to prevent nosocomial transmission of A. baumannii in ICU.

    Objective To determine the effect of feedback and education regarding the use of predicted body weight to adjust tidal volume in a lung-protective mechanical ventilation strategy. Methods The study was performed from October 2014 to November 2015 (12 months) in a single university polyvalent intensive care unit. We developed a combined intervention (education and feedback), placing particular attention on the importance of adjusting tidal volumes to predicted body weight bedside. In parallel, predicted body weight was estimated from knee height and included in clinical charts. Results One hundred fifty-nine patients were included. Predicted body weight assessed by knee height instead of visual evaluation revealed that the delivered tidal volume was significantly higher than predicted. After the inclusion of predicted body weight, we observed a sustained reduction in delivered tidal volume from a mean (standard error) of 8.97 ± 0.32 to 7.49 ± 0.19mL/kg (p < 0.002). Furthermore, the protocol adherence was subsequently sustained for 12 months (delivered tidal volume 7.49 ± 0.54 versus 7.62 ± 0.20mL/kg; p = 0.103). Conclusion The lack of a reliable method to estimate the predicted body weight is a significant impairment for the application of a worldwide standard of care during mechanical ventilation. A combined intervention based on education and repeated feedbacks promoted sustained tidal volume education during the study period (12 months). PMID:27925055

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

    Background: Although tracheal tubes are essential devices to control and protect airway in a critical care unit (CCU), they are not free from complications. Aims: To document the incidence and nature of airway accidents in the CCU of a government teaching hospital in Eastern India. Methods: Retrospective analysis of all airway accidents in a 5-bedded (medical and surgical) CCU. The number, types, timing, and severity of airway accidents were analyzed. Results: The total accident rate was 19 in 233 intubated and/or tracheostomized patients over 1657 tube days (TDs) during 3 years. Fourteen occurred in 232 endotracheally intubated patients over 1075 endotracheal tube (ETT) days, and five occurred in 44 tracheostomized patients over 580 tracheostomy TDs. Fifteen accidents were due to blocked tubes. Rest four were unplanned extubations (UEs), all being accidental extubations. All blockages occurred during night shifts and all UEs during day shifts. Five accidents were mild, the rest moderate. No major accident led to cardiorespiratory arrest or death. All blockages occurred after 7th day of intubation. The outcome of accidents were more favorable in tracheostomy group compared to ETT group (P = 0.001). Conclusions: The prevalence of airway accidents was 8.2 accidents per 100 patients. Blockages were the most common accidents followed by UEs. Ten out of the 15 blockages and all 4 UEs were in endotracheally intubated patients. Tracheostomized patients had 5 blockages and no UEs.

    This report identifies sites located on public or acquired lands of the United States containing residual radioactive materials and other radioactive waste (excluding waste resulting from the production of electric energy) and was developed in accordance with the provisions of Section 114(b) of Public Law 95-604, "Uranium Mill Tailings Radiation Control Act of 1978," enacted on November 8, 1978. Additionally, the report specifies which Federal agency has jurisdiction over such sites and, where appropriate data were available, provides a description of the radiological status of each of the sites reported. For purpose of providing a timely report t o t h e Congress, a termination date of May 31, 1979 was established for the receipt, correlation, and analysis of the input data. As of this date, residual radioactive materials and other radioactive waste have been identified by six Federal agencies at 48 sites throughout the United States. Table 1 on page vi provides a summary listing of the number of sites under the jurisdiction of each of these reporting agencies. A cross listing in tabular form by affected state is presented in Table 2 on page viii. Of the 48 sites reported, 36 are located i n three western states - Colorado (27 sites), Wyoming (5 sites), and Utah (4 sites). Based upon t h e data submitted, the sites were categorized into three broad radiological status categories -- controlled, unstabilized, and risk to the public. At controlled sites, the residue is stabilized, access t o t h e site is controlled, the s i t e is well monitored, and does not currently constitute a risk to the public. At sites in the unstabilized category, a probability exists for the spread of contamination. Sites in the risk category contain residue which represents a long-term risk to the public under present conditions. Of the 48 reported sites,. 9 (approximately 19%) could be classified in the controlled category; 38 (approximately 79%) were in the unstabilized category and

  3. HEAT STORAGE SYSTEM WITH PHASE CHANGE MATERIALS IN COGENERATION UNITS: STUDY OF PRELIMINARY MODEL

    Full Text Available The continuous increase in the mechanization of farm activities, the rise in fuel prices and the environmental aspects concerning gas emissions are the main driving forces behind efforts toward more effective use of renewable energy sources and cogeneration systems even in agricultural and cattle farms. Nevertheless these systems are still not very suitable for this purpose because of their little flexibility in following the changing energy demand as opposed to the extremely various farm load curves, both in daytime and during the year. In heat recovery systems, the available thermal energy supply is always linked to power production, thus it does not usually coincide in time with the heat demand. Hence some form of thermal energy storage (TES is necessary in order to reach the most effective utilization of the energy source. This study deals with the modelling of a packed bed latent heat TES unit, integrating a cogeneration system made up of a reciprocating engine. The TES unit contains phase change materials (PCMs filled in spherical capsules, which are packed in an insulated cylindrical storage tank. Water is used as heat transfer fluid (HTF to transfer heat from the tank to the final uses, and exhausts from the engine are used as thermal source. PCMs are considered especially for their large heat storage capacity and their isothermal behaviour during the phase change processes. Despite their high energy storage density, most of them have an unacceptably low thermal conductivity, hence PCMs encapsulation technique is adopted in order to improve heat transfer. The special modular configuration of heat exchange tubes and the possibility of changing water flow through them allow to obtain the right amount of thermal energy from the tank, according to the hourly demand of the day. The model permits to choose the electrical load of the engine, the dimensions of the tank and the spheres, thickness and diameter of heat exchanger and the nature of

    The main benefit of electric cars is to reduce air pollution in cities that is thus desirable to equip them with non polluting air conditioning units and this rules out frigorific compressors operating with CFC. The planned replacement of CFC by HFC is at best an interim solution. The best solution is certainly to use thermoelectric air conditioning units, which are inherently pollution-free. However, these have a fairly low COPF when compared to traditional compressor units. We study the relationship between the cooling of the interior of urban electric cars and the merit factor of the thermoelectric material in their Peltier unit. This should help provide concrete target properties of future T E materials. copyright 1995 American Institute of Physics

    Highlights: • A novel open heat pipe thermal storage unit is design to improve its performance. • Mechanism of its operation is phase-change heat transfer. • Tubular canisters with phase change material were placed in thermal storage unit. • Experiment and analysis are carried out to investigate its operation properties. - Abstract: A novel open thermosyphon-type thermal storage unit is presented to improve design and performance of heat pipe type thermal storage unit. In the present study, tubular canisters filled with a solid–liquid phase change material are vertically placed in the middle of the thermal storage unit. The phase change material melts at 100 °C. Water is presented as the phase-change heat transfer medium of the thermal storage unit. The tubular canister is wrapped tightly with a layer of stainless steel mesh to increase the surface wettability. The heat transfer mechanism of charging/discharging is similar to that of the thermosyphon. Heat transfer between the heat resource or cold resource and the phase change material in this device occurs in the form of a cyclic phase change of the heat-transfer medium, which occurs on the surface of the copper tubes and has an extremely high heat-transfer coefficient. A series of experiments and theoretical analyses are carried out to investigate the properties of the thermal storage unit, including power distribution, start-up performance, and temperature difference between the phase change material and the surrounding vapor. The results show that the whole system has excellent heat-storage/heat-release performance

    Although traditional departments of anatomy are vanishing from medical school rosters, anatomical education still remains an important part of the professional training of physicians. It is of some interest to examine whether history can teach us anything about how to reform modern anatomy. Are there lessons to be learned from the history of anatomical teaching in the United States that can help in the formulation of contents and purposes of a new anatomy? This question is explored by a review of US anatomical teaching with special reference to Franklin Paine Mall and the University of Michigan Medical School. An historical perspective reveals that there is a tradition of US anatomical teaching and research that is characterized by a zeal for reform and innovation, scientific endeavor, and active, student-driven learning. Further, there is a tradition of high standards in anatomical teaching through the teachers' engagement in scientific anatomy and of adaptability to new requirements. These traditional strengths can inform the innovation of modern anatomy in terms of its two duties--its duty to anatomy as a science and its duty toward anatomical education.

    2007-01-01

    In association with monitoring of reactor pressure vessel (RPV) fracture toughness, surveillance capsule test specimens have been used to monitor the material property of nuclear reactor vessel. As far as Kori Unit 1 is concerned, 6 capsules were put into the vessel before commercial operation of the plant. Up to now, all the six capsules have been withdrawn to test and monitor the fracture toughness of RPV material. The last capsule has been withdrawn on June this year, and the Kori unit 1 has been shut downed since July 2007 and will be shut downed until December this year for about 6 months, preparing the life extension of the plant to operate the plant 10 more years. With the situation that all the surveillance capsules have been withdrawn, public ask the following question, 'To extend the life of Kori Unit 1 more than 10 years, is it necessary to insert new surveillance capsules into the Kori Unit 1 to monitor RPV material fracture toughness?' In connection with this issue, planning project have been carried out since spring this year. In this paper, it is described that inserting new surveillance capsule into the Kori Unit 1 RPV has some meaning in some public acceptance point of view and is not necessary in material engineering point of view

    Surveillance testing for reactor vessel materials is performed in order to evaluate the irradiation embrittlement due to neutrons during operation and set the condition of safe operation of nuclear reactor. The 5th surveillance testing was performed primarily by Korea Atomic Energy Research Institute and Westinhouse corporation partially involved in testing and calculation data evaluation in order to obtain reliable test result. Fast neutron fluences for capsule V, T, S, R and P were 5.087E+18, 1.115E+19, 1.228E+19, 2.988E+19, and 3.938E+19n/cm2, respectively. The bias factor, the ratio of calculation/measurement, was 0.940 for the 1st through 5th testing and the calculational uncertainty, 7% satisfied the requirement of USNRC Reg.Guide DG-1053, 20%. The best estimated neutron fluence for reactor vessel inside surface was 1.9846E+19n/cm{sup 2} based on the end of 17th fuel cycle and it was predicted that the fluences of vessel inside surface at 24, 32, 40 and 48EFPY would reach 3.0593E+19, 4.0695E+19, 5.0797E+19 and 6.0900E+19n/cm{sup 2} based on the current calculation. PTS analysis for Kori unit 1 showed that 27.93EFPY was the threshold value for 300 deg F requirement. 71 refs., 33 figs., 52 tabs. (Author)

    Expandable habitable elements are an enabling technology for human exploration in space and on planetary surfaces. Large geometries can be deployed from a small launch volume, allowing greater mission capability while reducing mass and improving robustness over traditional rigid shells. This report describes research performed by ILC Dover under the Intelligent Flexible Materials for Space Structures program on the design and manufacture of softgoods for LaRC's Expandable Habitat Engineering Development Unit (EDU). The EDU is a full-scale structural test article of an expandable hybrid habitat, integrating an expandable softgoods center section with two rigid end caps. The design of the bladder, restraint layer and a mock-up Thermal Micrometeoroid Cover is detailed together with the design of the interface hardware used to attach them to the end caps. The integration and design of two windows and a floor are also covered. Analysis was performed to study the effects of the open weave design, and to determine the correct webbing and fabric configuration. Stress analyses were also carried out on the interfaces between the softgoods and the end caps and windows. Testing experimentally determined the strength of the fabric and straps, and component testing was used to proof several critical parts of the design. This program established new manufacturing and design techniques that can be applied to future applications in expandable structures.

    2010-01-01

    Across large scales, the carbon (C) flux of down woody material (DWM) detrital pools has largely been simulated based on forest stand attributes (e.g., stand age and forest type). The annual change in forest DWM C stocks and other attributes (e.g., size and decay class changes) was assessed using a forest inventory in the north central United States to provide an empirical assessment of strategic-scale DWM C flux. Using DWM inventory data from the USDA Forest Service's Forest Inventory and Analysis program, DWM C stocks were found to be relatively static across the study region with an annual flux rate not statistically different from zero. Mean C flux rates across the study area were -0.25, -0.12, -0.01, and -0.04 (Mg/ha/yr) for standing live trees, standing dead trees, coarse woody debris, and fine woody debris, respectively. Flux rates varied in their both magnitude and status (emission/sequestration) by forest types, latitude, and DWM component size. Given the complex dynamics of DWM C flux, early implementation of inventory re measurement, and relatively low sample size, numerous future research directions are suggested.

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

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

    Acinetobacter baumannii is an opportunistic pathogen that has become a major cause of concern, since it is a frequent cause of healthcare-associated infections (HAIs). The aim of the study was to describe the occurrence, the management and the control of an outbreak that occurred in an intensive care unit (ICU) of a teaching hospital in Southern Italy caused by multiple strains of extensively drug-resistant A. baumannii (XDRAB). Case-patient was defined as a patient with an healthcare-associated infection caused by an XDRAB isolate identified in a clinically significant culture. Environmental samples were collected from different surfaces. The isolates were identified by typical Gram stain morphology, using the Vitek 2 system (bioMérieux, France) and by MALDI-TOF MS mass spectrometry (bioMèrieux, France). Genotyping was performed through rep-PCR analysis. A patient presented an XDRAB ventilator-associated pneumonia at admission and was managed with strict isolation precautions until discharge. Five patients had a ventilator-associated pneumonia and two had a central line-associated bloodstream infection. Of the environmental samples, 1 sample obtained from the side of the bed of an infected patient yielded growth of XDRAB. Infection control measures were adopted. Rep-PCR analysis identified four patterns. The integration of epidemiological and microbiological data and the application of infection control measures were crucial to bring such an outbreak to a rapid halt. The distinctive characteristic of this study was the complex molecular pattern of the outbreak, which subsided in a short period of time due to adherence to infection-control measures, confirming the fundamental role of molecular typing in the comprehension of outbreaks dynamics and of integrated control interventions for the interruption of epidemic events.

    The objectives of our study were to analyse the prescriptions of antibiotics and assessing the relevance of pharmacist interventions (PI) in outpatient consultations in a pediatric unit of a Teaching Hospital of Abidjan, Côte d'Ivoire. We conducted a cross-sectional descriptive study from May to December 2013. The analysis of antibiotic prescriptions was documented. The tool of PI classification validated by the French Society of Clinical Pharmacy was used. The PI rating was made by prescribers. This rating evolved from PI0 to PI3 depending on the severity of the clinical impact of the problem and to the severity of clinical consequences avoided by the PI. The relevance was evaluated by the PI acceptance rate by physicians and clinical evaluation of their impact. Our study included 150 patients with a mean age of 11.75 months and a sex ratio (M/F) of 2. The amoxicillin-clavulanic acid (27.2 %) and amoxicillin (22.3 %) were the most prescribed antibiotics. Sixty-three drug-related problems (DRPs) were detected on the antibiotic prescriptions. They were non-optimal drug administration plan (88.9 %) and underdose (11.1 %). The amoxicillin-clavulanic acid (61.9 %) and josamycin (17.4 %) were the most affected by these DRPs. PI were related to the precision of modes of drug administration (88.9 %) and dose adjustments (11.1 %). The prescribers accepted 93.7 % of PIs. All accepted PIs was rated PI1 (significant clinical impact). PIs performed on antibiotic prescription were relevant with a high rate of acceptance and a significant clinical impact.

    Full Text Available Medication errors account for about 78% of serious medical errors in intensive care unit (ICU. So far no study has been performed in Iran to evaluate all type of possible medication errors in ICU. Therefore the objective of this study was to reveal the frequency, type and consequences of all type of errors in an ICU of a large teaching hospital. The prospective observational study was conducted in an 11 bed internal ICU of a university hospital in Shiraz. In each shift all processes that were performed on one selected patient was observed and recorded by a trained pharmacist. Observer would intervene only if medication error would cause substantial harm. The data was evaluated and then were entered in a form that was designed for this purpose. The study continued for 38 shifts. During this period, a total of 442 errors per 5785 opportunities for errors (7.6% occurred. Of those, there were 9.8% administration errors, 6.8% prescribing errors, 3.3% transcription errors and, 2.3% dispensing errors. Totally 45 interventions were made, 40% of interventions result in the correction of errors. The most common causes of errors were observed to be: rule violations, slip and memory lapses and lack of drug knowledge. According to our results, the rate of errors is alarming and requires implementation of a serious solution. Since our system lacks a well-organize detection and reporting mechanism, there is no means for preventing errors in the first place. Hence, as the first step we must implement a system where errors are routinely detected and reported.

    2016-01-01

    Objectives Dentists enrolled in the National Dental Practice-Based Research Network completed a study questionnaire about techniques and materials used for single-unit crowns and an enrollment questionnaire about dentist/practice characteristics. The objectives were to quantify dentists’ material recommendations and test the hypothesis that dentist’s and practice’s characteristics are significantly associated with these recommendations. Methods Surveyed dentists responded to a contextual scenario asking what material they would use for a single-unit crown on an anterior and posterior tooth. Material choices included: full metal, porcelain-fused-to-metal (PFM), all-zirconia, layered zirconia, lithium disilicate, leucite-reinforced ceramic, or other. Results 1,777 of 2,132 eligible dentists responded (83%). The top 3 choices for anterior crowns were lithium disilicate (54%), layered zirconia (17%), and leucite-reinforced glass ceramic (13%). There were significant differences (p<0.05) by dentist’s gender, race, years since graduation, practice type, region, practice busyness, hours worked/week, and location type. The top 3 choices for posterior crowns were all-zirconia (32%), PFM (31%), and lithium disilicate (21%). There were significant differences (p<0.05) by dentist’s gender, practice type, region, practice busyness, insurance coverage, hours worked/week, and location type. Conclusions Network dentists use a broad range of materials for single-unit crowns for anterior and posterior teeth, adopting newer materials into their practices as they become available. Material choices are significantly associated with dentist’s and practice’s characteristics. Clinical Significance Decisions for crown material may be influenced by factors unrelated to tooth and patient variables. Dentists should be cognizant of this when developing an evidence-based approach to selecting crown material. PMID:27693778

  7. Surface interactions between nanoscale iron and organic material: Potential uses in water treatment process units

    Science.gov (United States)

    Storms, Max

    Membrane systems are among the primary emergent technologies in water treatment process units due to their ease of use, small physical footprint, and high physical rejection. Membrane fouling, the phenomena by which membranes become clogged or generally soiled, is an inhibitor to optimal efficiency in membrane systems. Novel, composite, and modified surface materials must be investigated to determine their efficacy in improving fouling behavior. Ceramic membranes derived from iron oxide nanoparticles called ferroxanes were coated with a superhydrophillic, zwitterionic polymer called poly (sulfobetaine methacrylate) (polySBMA) to form a composite ceramic-polymeric membrane. Membrane samples with and without polySBMA coating were subjected to fouling with a bovine serum albumin solution and fouling was observed by measuring permeate flux at 10 mL intervals. Loss of polySBMA was measured using total organic carbon analysis, and membrane samples were characterized using x-ray diffraction, scanning electron microscopy, and optical profilometry. The coated membrane samples decreased initial fouling rate by 27% and secondary fouling rate by 24%. Similarly, they displayed a 30% decrease in irreversible fouling during the initial fouling stage, and a 27% decrease in irreversible fouling in the secondary fouling stage; however, retention of polySBMA sufficient for improved performance was not conclusive. The addition of chemical disinfectants into drinking water treatment processes results in the formation of compounds called disinfection by-products (DBPs). The formation of DBPs occurs when common chemical disinfectants (i.e. chlorine) react with organic material. The harmful effects of DBP exposure require that they be monitored and controlled for public safety. This work investigated the ability of nanostructured hematite derived from ferroxane nanoparticles to remove organic precursors to DBPs in the form of humic acid via adsorption processes. The results show that p

    Full Text Available Objective: To determine, by phenotypic and genotypic methods, oxacillin susceptibility in Staphylococcus aureus strains isolated from pediatric and neonatal intensive care unit patients seen at the University Hospital of the Botucatu School of Medicine.Methods: A total of 100 S. aureus strains isolated from the following materials were studied: 25 blood cultures, 21 secretions, 12 catheters, 3 cannulae and one chest drain from 62 patients in the neonatal unit, and 36 blood cultures, one pleural fluid sample and one peritoneal fluid sample from 38 patients in the pediatric unit. Resistance of the S. aureus isolates to oxacillin was evaluated by the disk diffusion method with oxacillin (1 μg and cefoxitin (30 μg, agar screening test using Mueller-Hinton agar supplemented with 6 μg/ml oxacillin and 4% NaCl, and detection of the mecA gene by PCR. In addition, the isolates were tested for β-lactamase production using disks impregnated with Nitrocefin and hyperproduction of β-lactamase using amoxicillin (20 μg and clavulanic acid (10 μg disks.Results: Among the 100 S. aureus strains included in the study, 18.0% were resistant to oxacillin, with 16.1% MRSA being detected in the neonatal unit and 21.0% in the pediatric unit. The oxacillin (1 μg and cefoxitin (30 μg disk diffusion methods presented 94.4% and 100% sensitivity, respectively, and 98.8% specificity. The screening test showed 100% sensitivity and 98.8% specificity. All isolates produced β-lactamase and one of these strains was considered to be a hyperproducer.Conclusions: The 30 μg cefoxitin disk diffusion method presented the best result when compared to the 1 μg oxacillin disk. The sensitivity of the agar screening test was similar to that of the cefoxitin disk diffusion method and higher than that of the oxacillin disk diffusion method.

The aim of this pilot study was to evaluate a filmed simulated pharmacological clinical scenario as a teaching resource in an undergraduate pharmacological unit. Pilot cross-sectional quantitative survey. An Australian university. 32 undergraduate students completing a healthcare degree including nursing, midwifery, clinical science, health science, naturopathy, and osteopathy. As a part of an undergraduate online pharmacology unit, students were required to watch a filmed simulated pharmacological clinical scenario. To evaluate student learning, a measurement instrument developed from Bloom's cognitive domains (knowledge, comprehension, application, analysis, synthesis and evaluation) was employed to assess pharmacological knowledge conceptualisation and knowledge application within the following fields: medication errors; medication adverse effects; medication interactions; and, general pharmacology. The majority of participants were enrolled in an undergraduate nursing or midwifery programme (72%). Results demonstrated that the majority of nursing and midwifery students (56.52%) found the teaching resource complementary or more useful compared to a lecture although less so compared to a tutorial. Students' self-assessment of learning according to Bloom's cognitive domains indicated that the filmed scenario was a valuable learning tool. Analysis of variance indicated that health science students reported higher levels of learning compared to midwifery and nursing. Students' self-report of the learning benefits of a filmed simulated clinical scenario as a teaching resource suggest enhanced critical thinking skills and knowledge conceptualisation regarding pharmacology, in addition to being useful and complementary to other teaching and

    2013-08-01

    A two-dimensional model was established to study the dynamic characteristics of a quartz crystal resonator with the upper surface covered by an array of hemispherical material units. A frequency-dependent equivalent mass ratio was proposed to simulate the effect of the covered units on frequency shift of the resonator system. It was found that the equivalent mass ratio alternately becomes positive or negative with change of shear modulus and radius of each material unit, which indicates that the equivalent mass ratio is strongly related to the vibration mode of the covered loadings. The further numerical results show the cyclical feature in the relationship of frequency shift and shear modulus/radius as expected. The solutions are useful in the analysis of frequency stability of quartz resonators and acoustic wave sensors.

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

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

    International Nuclear Information System (INIS)

    Huebel, Horst

    2010-01-01

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

    Ganz, Jennifer B; Flores, Margaret M

    2009-01-01

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

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

    Science.gov (United States)

    Pelch, Michael Anthony

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

    2012-01-01

    Full Text Available The Ti-6Al-4V octahedral porous material unit is designed to calculate its load. In this paper, ANSYS is adopted for the load simulation of the unit. And a simplified model of dimensional theoretical calculation is established, by which the analytical equation of the fracture load is obtained and the calculation of the load of Ti-6Al-4V is completed. Moreover, selective laser melting is adopted in processing the Ti-6Al-4V porous material unit. The experimental value of fracture load of this material is obtained through compression experiment. The results show that the simulation curves approximate the variation tendency of the elastic deformation of the compression curves; the curves of theoretical calculation approximate the general variation tendency; and the experimental value of fracture load is very close to the theoretical value. Therefore, the theoretical prediction accuracy of fracture load is high, which lays the foundation for the mechanical properties of the octahedral porous material.

    Nosocomial pneumonia poses great challenge to an intensivist. Detailed information about hospital-acquired pneumonia (HAP) and ventilator-acquired pneumonia (VAP) is crucial for prevention and optimal management, thus improving quality Intensive Care Unit (ICU) care. Hence, we aimed to study the current trend of nosocomial pneumonia in ICU. It was a prospective observational cohort study, conducted in the ICU of a tertiary care teaching public hospital over a period of 18 months. We studied clinical profile and outcome of 120 adult patients who developed VAP/HAP during the study period. We also analyzed the causative organisms, antibiotic sensitivity, and resistance pattern in these patients. Out of 120 patients, 29 patients were HAP and 91 patients were VAP. Mortality was 60% (72), and development of VAP and requirement of mechanical ventilation showed significant association with mortality (P antibiotiques et le modèle de résistance chez ces patients. Résultats: Sur 120 patients, 29 patients étaient HAP et 91 patients étaient VAP. La mortalité était de 60% (72), et le développement du VAP et l'exigence de ventilation mécanique ont montré une association significative avec la mortalité (P antibiotique maximale a été observée chez la pipéracilline + tazobactam (58,8%), suivie de l'imipénème (49,5%) et du méropénem (41,8%), alors que la résistance antibiotique maximale a été observée à cefépime (95,1%), suivie de ceftazidime et de l'amoxicilline (91,2%) . la pneumonie nosocomiale a montré une incidence élevée (17,44%) et la mortalité (60%). Les organismes communs identifiés étaient S. aureus et K. pneumoniae. La résistance était élevée pour les antibiotiques couramment utilisés et une forte sensibilité aux antibiotiques pour la pipéracilline + le tazobactam et le carbapénème.

    To seek for high-performance small molecule donor materials used in heterojunction solar cell, six acceptor-donor-acceptor small molecules based on naphtho[2,3-b:6,7-b']dithiophene (NDT) units with different acceptor units were designed and characterized using density functional theory and time-dependent density functional theory. Their geometries, electronic structures, photophysical, and charge transport properties have been scrutinized comparing with the reported donor material NDT(TDPP)2 (TDPP  =  thiophene-capped diketopyrrolopyrrole). The open circuit voltage (V(oc)), energetic driving force(ΔE(L-L)), and exciton binding energy (E(b)) were also provided to give an elementary understanding on their cell performance. The results reveal that the frontier molecular orbitals of 3-7 match well with the acceptor material PC61 BM, and compounds 3-5 were found to exhibit the comparable performances to 1 and show promising potential in organic solar cells. In particular, comparing with 1, system 7 with naphthobisthiadiazole acceptor unit displays broader absorption spectrum, higher V(oc), lower E(b), and similar carrier mobility. An in-depth insight into the nature of the involved excited states based on transition density matrix and charge density difference indicates that all S1 states are mainly intramolecular charge transfer states with the charge transfer from central NDT unit to bilateral acceptor units, and also imply that the exciton of 7 can be dissociated easily due to its large extent of the charge transfer. In a word, 7 maybe superior to 1 and may act as a promising donor candidate for organic solar cell. Copyright © 2013 Wiley Periodicals, Inc.

    2001-01-01

    Just over five years ago, the Trilateral Initiative was launched to investigate the technical, legal and financial issues associated with IAEA verification of weapon-origin fissile material in the Russian Federation and the United States. Since then, the Joint Working Group has developed concepts and equipment suitable for such a verification mission, anticipating that the States would submit classified forms of fissile material to IAEA verification under new agreements developed for this purpose. This article summarizes the accomplishments to date and identifies the future steps foreseen under the Trilateral Initiative. As there is no legal commitment on the Parties to this Initiative as yet, the issues considered are still changing. Since it was launched, the Initiative has been given a sense of importance and weight, raising the expectations of the international community. The Final Document of the 2000 Conference on the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), for example, under the review of Article VI of the Treaty, includes the statement to 'complete and implement the Trilateral Initiative'. It was launched following independent statements by the President of the United States beginning in 1993, and by the President of the Russian Federation in 1996. It is an Initiative between the IAEA, the Russian Federation and the United States that is in the context of Article VI of the NPT. The intention is to examine the technical, legal and financial issues associated with IAEA verification of weapon origin and other fissile material released from defense programmes in those two countries

    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

  18. Demand forecast for rail shipment of radioactive material in the United States

    International Nuclear Information System (INIS)

    Allen, G.C.; Cashwell, J.W.

    1981-01-01

    A summary of the market potential for radioactive material (in millions of ton-miles) is presented in tabular form. These include the following: milled uranium ore; mill tailings; natural uranium hexafluoride; enriched uranium hexafluoride; fresh fuel, spent fuel; low-level waste; transuranic waste; and high-level waste. The maximum realistic market share for rail carriers is always less than these values because of the lack of rail access to some shipping and receiving facilities, small material quantities which could most easily move by other modes, short shipping distances for certain transport segments and greater operational convenience of other modes for some material categories. While market share and revenues for radioactive material are presently small, rail carriers appear to have a market advantage for milled uranium ore, transuranic waste and high-level waste. The potential for a significantly increased market share exists for spent fuel and uranium hexafluoride. While more fresh fuel and low-level waste can be transported by rail, it is unlikely that rail market share for radioactive materials (RAM) in general will rise to the potential maximum because many of these materials have historically been moved by truck and transported in frequent, small shipments

    2018-01-01

    International studies of science education, such as the Trends in Mathematics and Science Study (TIMSS), have revealed considerable national disparities in students' achievements in science education. The results have prompted many nations to compare their science education systems and practices to those of others, to gain insights for improvement. Teacher training and professional development are key educational components that have not attracted as much attention as they deserve in international comparative studies. This study compares the conceptions and attitudes of pre-service elementary teachers (PSETs) in Hong Kong and the United States with respect to inquiry science learning and teaching at the beginning of the semester before the start of the science methods course. PSETs' conceptions and attitudes in the two countries were compared by means of a questionnaire with both Likert-type and open-ended questions. Quantitative data were analyzed using exploratory factor analysis and inferential statistics, while qualitative data were analyzed through the systematic categorization of PSETs' responses into broad themes and subthemes to reflect patterns in their conceptions of and attitudes toward inquiry science learning and teaching. The results revealed a complex interplay between PSETs' conceptions of and attitudes toward inquiry science learning and teaching. The results shed light on the effects of sociocultural contexts and have important implications for the design of science methods courses.

    Griggs, E. I.; Pitts, D. R.; Humphries, W. R.

    1974-01-01

    The transient response of a single cell of a typical phase change material type thermal capacitor has been modeled using numerical conductive heat transfer techniques. The cell consists of a base plate, an insulated top, and two vertical walls (fins) forming a two-dimensional cavity filled with a phase change material. Both explicit and implicit numerical formulations are outlined. A mixed explicit-implicit scheme which treats the fin implicity while treating the phase change material explicitly is discussed. A band algorithmic scheme is used to reduce computer storage requirements for the implicit approach while retaining a relatively fine grid. All formulations are presented in dimensionless form thereby enabling application to geometrically similar problems. Typical parametric results are graphically presented for the case of melting with constant heat input to the base of the cell.

    2010-12-01

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

  18. Assessment of extent and degree of thermal damage to polymeric materials in the Three Mile Island Unit 2 reactor building

    International Nuclear Information System (INIS)

    Alvares, N.J.

    1986-01-01

    This paper describes assumptions and procedures used to perform thermal damage analysis caused by post loss-of-coolant-accident (LOCA) hydrogen deflagration at Three Mile Island Unit 2 Reactor. Examination of available photographic evidence yields data on the extent and range of thermal and burn damage. Thermal damage to susceptible material in accessible regions of the reactor building was distributed in non-uniform patterns. No clear explanation for non-uniformity was found in examined evidence, e.g., burned materials were adjacent to materials that appear similar but were not burned. Because these items were in proximity to vertical openings that extend the height of the reactor building, the authors assume the unburned materials preferentially absorbed water vapor during periods of high, local steam concentration. A control pendant from the polar crane located in the top of the reactor building sustained asymmetric burn damage of decreasing degree from top to bottom. Evidence suggests the polar-crane pendant side that experienced heaviest damage was exposed to intense radiant energy from a transient fire plume in the reactor containment volume. Simple hydrogen-fire-exposure tests and heat transfer calculations approximate the degree of damage found on inspected materials from the containment building and support for an estimated 8% pre-fire hydrogen

This in vitro study compared the temperature rise under demineralized human tooth dentin during light-curing and the degrees of conversion (DCs of three different RBMs using quartz tungsten halogen (QTH and light-emitting diode (LED units (LCUs. Materials and Methods Demineralized and non-demineralized dentin disks were prepared from 120 extracted human mandibular molars. The temperature rise under the dentin disks (n = 12 during the light-curing of three RBMs, i.e. an Ormocer-based composite resin (Ceram. X, Dentsply DeTrey, a low-shrinkage silorane-based composite (Filtek P90, 3M ESPE, and a giomer (Beautifil II, Shofu GmbH, was measured with a K-type thermocouple wire. The DCs of the materials were investigated using Fourier transform infrared spectroscopy. Results The temperature rise under the demineralized dentin disks was higher than that under the non-demineralized dentin disks during the polymerization of all restorative materials (p 0.05. Conclusions Although there were no significant differences in the DCs, the temperature rise under demineralized dentin disks for the silorane-based composite was higher than that for dimethacrylate-based restorative materials, particularly with QTH LCU.

    Full Text Available Cinema, since it’s beginning, has been and is a social thermometer of the first magnitude reflecting the inequities of the population, among them are infectious diseases.  The caudal of images, sounds, and feelings that appear in the field support a very valid teaching resource, capable of complementing the classic teaching method and adapting the dynamic art of teaching to the actual educational tendencies.  If the definition of objectives and the teaching design are obligatory stages that should always be realized with rigor, in a method like this, because of its characteristics and youth, the control should be more exhaustive –before, during and after its execution- to avoid the “trivialization” to gain the maximum teaching efficiency that depends no as much on the material utilized (and its fundamental selection of films to accompany every unit taught like the use that is made of it.

    2018-06-05

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

    1996-01-01

    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

  13. Remote Detection and Location of Illegal Radioactive Materials Units in Uzbekistan

    International Nuclear Information System (INIS)

    2007-01-01

    Uzbekistan is a checkpoint for transportation between Russia and some Asian countries, such as Iran, Pakistan, Afghanistan and Tajikistan that might be attractive destinations for those smuggling nuclear materials or weapons. Currently there are over 200 border crossing points. Most of them have equipped with monitors able to reliably detect nuclear materials. Uzbekistan also has substantial radioactive ore mining, and these monitors also allow the Customs Service to maintain safe conditions for their inspectors as well as for population of Uzbekistan and its neighbors. But it is very important to detect radioactive materials inland, their location and travel. This task cannot be solved by using stationary detectors which are used at border crossing points. New method, electronic scheme and software for remote detection, location and travel of radioactive sources were developed. The operation principle lies in detection of radiation by 6 detectors situated in a leaden cylindrical shield collimating gamma-radiation in 6 directions. Besides the detection system contains 6 amplifiers, 6 counters and JPS-system connected with computer. The detection system is transported by car. Field tests of the detection system have shown that the detection limit is 5. 106 Bq and 4.106 Bq for Co60 and Cs137 respectively when the radioactive sources distance is 400 m. (author)

    Jonter, T.

    1999-05-01

    This report deals mainly with the United States nuclear energy policy towards Sweden 1945-1960. Although Sweden contained rich uranium deposits and retained high competence in the natural sciences and technology, the country had to cooperate with other nations in order to develop the nuclear energy. Besides developing the civil use of nuclear power, the Swedish political elite also had plans to start a nuclear weapons programme. From the beginning of the 1950s up to 1968, when the Swedish parliament decided to sign the non-proliferation treaty, the issue was widely debated. In this report, American policy is analyzed in two periods. In the first period, 1945-1953, the most important aim was to prevent Sweden from acquiring nuclear materials, technical know-how, and advanced equipment which could be used in the production of nuclear weapons. The Swedish research projects were designed to contain both a civil and military use of nuclear energy. The first priority of the American administration was to discourage the Swedes from exploiting their uranium deposits, especially for military purposes. In the next period, 1953-1960, the American policy was characterized by extended aid to the development of the Swedish energy programme. Through the 'Atoms for Peace'-programme, the Swedish actors now received previously classified technical information and nuclear materials. Swedish companies and research centers could now buy enriched uranium and advanced equipment from the United States. This nuclear trade was, however, controlled by the American Atomic Energy Commission (AEC). The American help was shaped to prevent the Swedes from developing nuclear weapons capability. From mid-50s Swedish politicians and defence experts realised that a national production of nuclear bombs would cost much more money than was supposed 4-5 years earlier. As a consequence, Swedish officials started to explore the possibilities of acquiring nuclear weapons from United States. The American

This study has been chosen one of the united research themes because it has been common objective for both Institutes in the research field of structural materials such as Fast Breeder Reactor and Light Water Reactors components. The purpose of the study is to clarify damage mechanism of structural materials under irradiation, and then to develop the methods for damage evaluation and detection in earlier stage of progressing process of damage along grain boundaries. In fiscal year 2003, magnetic flux density distribution (JNC) and micro-corrosion (JAERI) measurement apparatus were newly developed and equipped in Hot Facilities in two Institutes, respectively. The former apparatus, supersensitive Flux Gate sensor was installed, could detector leaked magnetic flux from material damaged by neutron irradiation. The latter one, Atomic Force Microscope was installed, could detect grain boundary corrosion loss after an electrochemical corrosion test of irradiated material. These apparatus were designed and produced in consideration of radiation resistance and remote-controlled operation to equip in hot cells. As the results of preliminary studies using Ni ion irradiated specimen, damage detection by corrosion property in grain boundary was possible but magnetic property change could not detect. We will start the study on neutron irradiation damage by employing the two apparatus as the next step. (author)

    The pulser/receiver constitutes the most vital part of an ultrasonic flaw detector or an ultrasonic imaging system used for inspection of materials. The ultrasonic properties of the material and resolution requirements govern the choice of the frequency of ultrasound that can be optimally used. The pulser/receiver in turn decides the efficiency of excitation of the transducer and the overall signal to noise ratio of the system for best sensitivity and resolution. A variety of pulsers are used in the ultrasonic instruments employed for materials inspection. This report describes a square wave type of an ultrasonic pulser-receiver unit developed at Ultrasonic Instrumentation Section, Electronics Division, BARC. It has been primarily designed for excitation of the transducer that is used with a multi-channel ultrasonic imaging system ULTIMA 100M targeted for inspection of SS403 billets, which are in turn used as the base material for fabrication of end fittings for coolant channels of pressurized heavy water nuclear reactors (PHWRs). The design of the pulser is based upon very fast MOSFETs, configured as electronic switches. The pulser is operated with a linear bipolar H.V. supply (+/- 500V max.). The receiver provides a 60 dB gain with a -3 dB BW of 40 MHz. This pulser/receiver unit has been successfully interfaced with a 4 channel ULTIMA 100 M4 multichannel ultrasonic C-scan imaging system, also designed and developed by the authors at Ultrasonic Instrumentation Section (Electronics Division, BARC) and supplied to Centre for Design and Manufacturer - CDM, BARC. This system is being regularly used in C-scan imaging mode for volumetric inspection of SS403 billets for end fittings of 500 MWe PHWRs. (author)

    Light-curing of resin-based materials (RBMs) increases the pulp chamber temperature, with detrimental effects on the vital pulp. This in vitro study compared the temperature rise under demineralized human tooth dentin during light-curing and the degrees of conversion (DCs) of three different RBMs using quartz tungsten halogen (QTH) and light-emitting diode (LED) units (LCUs). Demineralized and non-demineralized dentin disks were prepared from 120 extracted human mandibular molars. The temperature rise under the dentin disks (n = 12) during the light-curing of three RBMs, i.e. an Ormocer-based composite resin (Ceram. X, Dentsply DeTrey), a low-shrinkage silorane-based composite (Filtek P90, 3M ESPE), and a giomer (Beautifil II, Shofu GmbH), was measured with a K-type thermocouple wire. The DCs of the materials were investigated using Fourier transform infrared spectroscopy. The temperature rise under the demineralized dentin disks was higher than that under the non-demineralized dentin disks during the polymerization of all restorative materials (p 0.05). Although there were no significant differences in the DCs, the temperature rise under demineralized dentin disks for the silorane-based composite was higher than that for dimethacrylate-based restorative materials, particularly with QTH LCU.

  3. 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.

    2001-01-01

    A Protection from Radiation Act was enacted in Tanzania in 1983 to regulate the use of ionizing radiation and protect people against its danger. The Act established a regulatory authority known as National Radiation Commission (NRC), which is the corporate body to enforce the law and regulations. From the beginning of 2000, the NRC has kept inventory of 200 and 324 radiation installations, and radiation sources and radioactive materials in the country, respectively; and has provided personnel monitoring services to 665 radiation workers. However, due to the trade liberalization that is currently being experienced in the country, the increase in the number of radiation practices is observed yearly. To cope with the situation, the whole system of notification, authorization, registration and licensing needs to be improved. The improvement has now started by amending the existing Protection from Radiation Act. (author)

    Reese, R.T.; Sandoval, R.P.

    1980-01-01

    The Transportation System Safety Evaluation (TSSE) program at Sandia National Laboratories' Transportation Technology Center was initiated to provide the necessary information on source terms for nuclear materials subjected to extreme environments. The techniques for derivation of source terms for the fuel alone has been described as well as the outline for package response. An additional facet of this problem is the development of analytical methods to describe the transport of the released radionuclides from the fuel rods to possible release points. This work is also covered in the TSSE program. Not all the work required will be performed or funded by Sandia; rather existing work will be sought out and ongoing work will be utilized in an attempt to unify the presentation of data and thus increase its usefulness

    The paper is devoted to studying the thermoelectric and structural properties of films based on metal nanoclusters (Au, Pd, Pt). The experimental results of the study of single nanoclusters’ tunneling conductance obtained with scanning tunneling spectroscopy are presented. The obtained data allowed us to evaluate the thermoelectric power of thin film consisting of densely packed individual nanoclusters. It is shown that such thin films can operate as highly efficient thermoelectric materials. A scheme of miniature thermoelectric radioisotope power source based on the thorium-228 isotope is proposed. The efficiency of the radioisotope battery using thermoelectric converters based on nanocluster metal films is shown to reach values up to 1.3%. The estimated characteristics of the device are comparable with the parameters of up-to-date radioisotope batteries based on nickel-63.

  8. Emergency response capabilities developed in the United States to deal with nuclear materials transportation accidents

    1980-01-01

    The non-existence of emergency response programs is frequently stated as a reason for restricting the movement of radioactive materials through states or local jurisdictions. Yet, studies discussed here indicate that emergency response capability, while not in the best condition, is getting more money, interest and attention, and in most states response networks exist which could be effective in responding to radiological emergencies. Awareness of such capabilities by the public is an important feature in increasing the public's confidence in the ability of federal, state and local officials in controlling hazards. One aspect of this awareness program could be in broader availability of radioactive emergency techniques for possible first responders to emergencies. This training, public awareness and more emphasis on workable emergency plans will help to assure reliable and workable emergency response plans

    In the coming year a global geological map of Ganymede will be completed that represents the most recent understanding of the satellite on the basis of Galileo mission results. This contribution builds on important previous accomplishments in the study of Ganymede utilizing Voyager data and incorporates the many new discoveries that were brought about by examination of Galileo data. Material units have been defined, structural landforms have been identified, and an approximate stratigraphy has been determined utilizing a global mosaic of the surface with a nominal resolution of 1 km/pixel assembled by the USGS. This mosaic incorporates the best available Voyager and Galileo regional coverage and high resolution imagery (100-200 m/pixel) of characteristic features and terrain types obtained by the Galileo spacecraft. This map has given us a more complete understanding of: 1) the major geological processes operating on Ganymede, 2) the characteristics of the geological units making up its surface, 3) the stratigraphic relationships of geological units and structures, and 4) the geological history inferred from these relationships. A summary of these efforts is provided here.

    A simple and practical surface grafting approach was developed to introduce rechargeable N-halamine-based antimicrobial functionality onto the inner surfaces of continuous small-bore polyurethane (PU) dental unit waterline (DUWL) tubing. In this approach, tetrahydrofuran (THF) solution of a free-radical initiator, dicumyl peroxide (DCP), flowed through the PU tubing (inner diameter of 1/16 in., or 1.6 mm) to diffuse DCP into the tubing's inner walls, which was used as initiator in the subsequent grafting polymerization of methacrylamide (MAA) onto the tubing. Upon chlorine bleach treatment, the amide groups of the grafted MAA side chains were transformed into acyclic N-halamines. The reactions were confirmed with attenuated total reflectance infrared (ATR) spectra and iodometric titration. The mechanical properties of the tubing were not significantly affected by the grafting reactions. The biofilm-controlling function of the new N-halamine-based PU tubing was evaluated with Pseudomonas aeruginosa (P. aeruginosa), one of the most isolated water bacteria from DUWLs, in a continuous bacterial flow model. Bacteria culturing and SEM studies showed that the inner surfaces of the new N-halamine-based PU tubing completely prevented bacterial biofilm formation for at least three to four weeks. After that, bacteria began to colonize the tubing surface. However, the lost function was fully regenerated by exposing the tubing inner surfaces to diluted chlorine bleach. The recharging process could be repeated periodically to further extend the biofilm-controlling duration for long-term applications.

    The relative national environmental impacts of transporting spent fuel and other nuclear wastes to each of 9 candidate repository sites in the United States were analyzed for the 26-year period of repository operation. Two scenarios were examined for each repository: 1) shipment of 5-year-old spent fuel and Defence High-Level Waste (DHLW) directly from their points of origin to a repository (reference case); and 2) shipment of 5-year-old spent fuel to a Monitored Retrievable Storage (MRS) facility and shipment (by dedicated rail) of 10-year-old consolidated spent fuel from the MRS to a repository. Transport by either all truck or all rail from the points of origin were analyzed as bounding cases. The computational system used to analyze these impacts included the WASTES II logistics code and the RADTRAN III risk analysis code. The radiological risks for the reference case increased as the total shipment miles to a repository increased for truck; the risks also increased with mileage for rail but at a lower rate. For the MRS scenario the differences between repository sites were less pronounced for both modal options, because of the reduction in total shipment miles possible with the large dedicated rail casks. All the risks reported are small in comparison to the radiological risks due to 'natural background'

    The research sought to ascertain medical and dental libraries' collection development policies, evaluation methods, purchase decisions, and issues that relate to print and electronic United States Medical Licensing Examination (USMLE) and National Board Dental Examination (NBDE) preparation materials. The investigators surveyed librarians supporting American Association of Medical Colleges (AAMC)-accredited medical schools (n = 58/125) on the USMLE and librarians supporting American Dental Association (ADA)-accredited dental schools (n = 23/56) on the NBDE. The investigators analyzed the data by cross-tabulating and filtering the results using EFM Continuum web survey software. Investigators also surveyed print and electronic USMLE and NBDE preparation materials from 2004-2007 to determine the number of publications and existence of reviews. A majority of responding AAMC libraries (62%, n = 58) provide at least 1 electronic or online USMLE preparation resource and buy an average of 11.6 print USMLE titles annually. Due to a paucity of NBDE print and electronic resources, ADA libraries bought significantly fewer print resources, and only 1 subscribed to an electronic resource. The most often reported evaluation methods for both populations were feedback from medical or dental students, feedback from medical or dental faculty, and online trials. Some AAMC (10%, n = 58) and ADA libraries (39%, n = 23) libraries reported that no evaluation of these materials occured at their libraries. From 2004-2007, publishers produced 45 USMLE preparation resources (total n = 546) to every 1 NBDE preparation resource (total n = 12). Users' needs, institutional missions and goals, financial status, and official collection policies most often underlie decisions to collect or not collect examination preparation materials. Evaluating the quality of examination preparation materials can be problematic due to lack of published reviews, lack of usability testing by libraries, and

    Launched in 1986 by Electricite de France, the Probabilistic Safety Assessment of a French 1300 MWe Pressurized Water Reactor (called PSA 1300) was completed in 1989. The first objective was to assess the annual core damage frequency by identifying all the accident scenarii likely to contribute significantly to this frequency. The second objective of the study was to provide an automated computerized tool (software) for updating the assessment - in order to take new data and knowledge into account - and for performing numerous sensitivity studies easily. Its scope and characteristics render this study unique. Indeed, it required an effort amounting to 50 engineer-years. The results and the first lessons are presented in this paper. The PSA 1300 teachings will be extensively used for the design and operation of existing or future French nuclear power reactors

    Background: Sepsis is amongst the leading causes of admission to the intensive care units and is associated with a high mortality. However, data from developing countries is scarse. Aim of conducting this study was to determine the incidence, outcome and risk factors for sepsis on admission to surgical intensive care unit (SICU) of a teaching hospital in Pakistan. Methods: Two year retrospective observational study included all consecutive adult admissions to the surgical intensive care unit (SICU) of a University Hospital, from January 2012 to December 2013. Results: Two hundred and twenty-nine patients met the inclusion criteria. Average age of the patients was 46.35±18.23 years (16-85), mean Acute Physiology and Chronic Health Evaluation II (APACHE II) score was 15.92±8.13 and males were 67.6 percentage. Median length of ICU stay was 4 [IQR 5]. 43 percentage patients fulfilled the criteria of sepsis at the time of admission to the SICU and incidence of severe sepsis/septic shock was 35 percentage. Abdominal sepsis was the most frequent source of infection (57.5 percentage). The overall intensive care unit mortality was 32.31 percentage but the mortality of sepsis-group was 51.15 percentage as compared to 17.7 percentage of the non-sepsis group. Stepwise logistic regression model showed that increasing age, female gender, non-operative admission, admission under general surgery and co-morbidities like ischaemic heart disease and chronic kidney disease were significant predictors of sepsis. Conclusion: The incidence of sepsis and severe sepsis/septic shock, on admission to SICU is high and mortality of the sepsis group is nearly three times the mortality of the non-sepsis group.

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

    To investigate the circumstances and geographic and temporal distributions of hazardous material releases and resulting human impacts in the United States. Releases with fatalities, injuries, and evacuations were identified from reports to the National Response Center between 1990 and 2008, correcting for data quality issues identified in previous studies. From more than 550,000 reports, 861 deaths, 16,348 injuries and 741,427 evacuations were identified. Injuries from releases of chemicals at fixed facilities and natural gas from pipelines have decreased whereas evacuations from petroleum releases at fixed facilities have increased. Results confirm recent advances in chemical and pipeline safety and suggest directions for further improvement including targeted training and inspections and adoption of inherently safer design principles.

    A theoretical study was carried out to re-evaluate the integrity of the biological shielding of 137 Cs brachytherapy unit at the Korle Bu Teaching Hospital (Ghana), and the results were verified by measurement of the dose rates at selected locations. The primary objective was to determine the current state of protection and safety of staff and the general public. Shielding design of the brachytherapy unit at the hospital was based on postulated workload and occupancy factors of the facility. The facility has been in existence for 12 y and has accumulated operational workload data that differs from the postulated one. The results show that despite the variation in actual and postulated workloads, the dose rates were below the reference values 0.5 mSv h -1 for public areas and 7.5 μSv h -1 for controlled areas. These values were in the range of 0.10-0.12 μSv h -1 for public areas and of 0.50-2.10 μSv h -1 for controlled areas. (authors)

    Japanese government established the system for renewing educational personnel certificates in 2007 and mandated the adoption of it in April 2009 (cf. “2007 White Paper on Education, Culture, Sports, Science and Technology”, available at http://www.mext.go.jp/english/). The new system shows that the valid period for each regular certificate after the renewal system adoption (April 1, 2009) is until the end of the fiscal year after ten years from satisfying the qualifications required for the certificate. Only persons who have attended over 30 hours and passed the examination in the certificate renewal courses before the expiration of the valid period can renew their certificate which is valid for next ten years. The purpose of this system is for teachers to acquire the latest knowledge and skills. Certificate renewal courses authorized by Ministry of Education, Culture, Sports, Science and Technology of Japan are offered by universities. Attendees will choose based on their specialty and awareness of issues from the various courses with education curriculums and. To renew their certificates, they should include (1) items regarding the latest trends and issues in education (12 hours) and (2) items regarding their speciality and other educational enhancement (three 6-hours course: total 18 hours). In 2008, before the adoption, provisional certificate renewal courses were offered for trial by more than 100 universities. The author offered a 6-hour course titled by “Development of teaching materials for school pupils to make understand the dynamic motion of the earth - utilising the results of the GPS ranging”. This course was targeted mainly for science teachers of middle- and high-schools. The goal of this course was for the attendees to understand the role of GPS ranging for the direct observation of the crustal movement and plate motion, and to produce the teaching materials possibly used in the classrooms. The offering of this course is aiming finally at

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

  5. The interaction with suspended and settled sedimentary materials of long-lived radionuclides discharged into United Kingdom coastal waters

    Low-level liquid radioactive wastes are routinely discharged under authorization into United Kingdom coastal waters from nuclear reactor sites, from nuclear fuel reprocessing and fabrication plants, and from other facilities connected with the nuclear industries. The effluents contain a wide range of radionuclides, with greatly varying half-lives and in different chemical forms. The receiving environments are also markedly different. All of these factors need to be taken into account in order that the authorizations for discharge are based on a sound knowledge of the underlying environmental science as well as meeting the objectives of radiological protection. The largest research effort has been expended on the longer-lived nuclides discharged from the BNFL plant at Sellafield into the Irish Sea. These studies have focused on such aspects as the nature of the effluent, the dispersion of the soluble nuclides out of the Irish Sea, the retention of other nuclides within it, and the incorporation of radionuclides into settled sediments. Some comparisons have also been made between other sites by observing the concentrations of radionuclides in similar materials, at similar distances, per unit rate of discharge. Although these studies are useful in developing an understanding of the dynamics of radionuclides in coastal environments, it is essential to have a wider and more general knowledge if the long-term consequences of discharging radionuclides—or any other chemical waste—into coastal waters are to be fully evaluated. These consequences are assessed by the use of models which have, necessarily, to simplify many of the processes involved. It is therefore all the more important that the underlying science relating to the nature and behaviour of the wastes, and of the receiving environment, is fully explored, and that the assumptions used in the models can be satisfactorily validated.

    The thermal storage unit consists of two concentric cylinders where the working fluid flows through the internal cylinder and the annulus is filled with a phase change material. The system carries out a cyclic operation; each cycle consists of two processes. In the charging process the hot working fluid enters the internal cylinder and transfers heat to the phase change material. In the discharging process the cold working fluid enters the internal cylinder and absorbs heat from the phase change material. The differential equations governing the heat transfer between the two media are solved numerically. The numerical results are compared with the experimental results available in the literature. The performance of an energy storage unit is directly related to the thermal conductivity of nano-particles. The energy consumption of a residential unit whose energy is supplied by a thermal storage system can be reduced by 43 % when using nano-particles.

  9. Capillary pressure-saturation relationships for porous granular materials: Pore morphology method vs. pore unit assembly method

    Sweijen, Thomas; Aslannejad, Hamed; Hassanizadeh, S. Majid

    2017-09-01

    In studies of two-phase flow in complex porous media it is often desirable to have an estimation of the capillary pressure-saturation curve prior to measurements. Therefore, we compare in this research the capability of three pore-scale approaches in reproducing experimentally measured capillary pressure-saturation curves. To do so, we have generated 12 packings of spheres that are representative of four different glass-bead packings and eight different sand packings, for which we have found experimental data on the capillary pressure-saturation curve in the literature. In generating the packings, we matched the particle size distributions and porosity values of the granular materials. We have used three different pore-scale approaches for generating the capillary pressure-saturation curves of each packing: i) the Pore Unit Assembly (PUA) method in combination with the Mayer and Stowe-Princen (MS-P) approximation for estimating the entry pressures of pore throats, ii) the PUA method in combination with the hemisphere approximation, and iii) the Pore Morphology Method (PMM) in combination with the hemisphere approximation. The three approaches were also used to produce capillary pressure-saturation curves for the coating layer of paper, used in inkjet printing. Curves for such layers are extremely difficult to determine experimentally, due to their very small thickness and the presence of extremely small pores (less than one micrometer in size). Results indicate that the PMM and PUA-hemisphere method give similar capillary pressure-saturation curves, because both methods rely on a hemisphere to represent the air-water interface. The ability of the hemisphere approximation and the MS-P approximation to reproduce correct capillary pressure seems to depend on the type of particle size distribution, with the hemisphere approximation working well for narrowly distributed granular materials.

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

    Full Text Available This work presents a numerical study of the thermal behavior of shell-and-tube latent thermal energy storage (LTES unit using two phase change materials (PCMs. The heat transfer fluid (HTF flow through the inner tube and transfer the heat to PCMs. First, a mathematical model is developed based on the enthalpy formulation and solved through the governing equations. Second, the effects of HTF inlet temperature on the unsteady temperature evolution of PCMs, the total energy stored evolution as well as the total melting time is studied. Numerical results show that for all HTF inlet temperature, melting rate of PCM1 is the fastest and that of PCM2 is the slowest; increasing the HTF inlet temperature considerably increases the temperature evolution of PCMs. The maximum energy stored is observed in PCM2 with high melting temperature and high specific heat; heat storage capacity is large for high HTF inlet temperature. When the HTF inlet temperature increases from 338 K to 353 K, decreasing degree of melting time of PCM2 is the biggest from 1870 s to 490 s, which reduces about 73.8%; decreasing degree of melting time of PCM1 is the smallest from 530 s to 270 s, which reduces about 49.1%.

    Prices of medical devices in Japan were previously reported to be 2 to 4 times higher than those in the United States in 1996 and 1997. However, such data are out of date. We previously compared the market prices in early 2005 between Japan and the US for 16 items in 10 categories of medical materials, and showed that price differences still existed for all these items. However, the number of items investigated was small for each category, and generalization of the results might have been limited. The present study conducted a further investigation into price information for multiple items for each category, focusing on 5 cardiovascular devices. The US market price information was obtained from interviews of a healthcare provider network and 2 different group-purchasing organizations. We could obtain price information on 19 items in 5 categories. We substituted the Japanese reimbursement prices for the Japanese market prices. The price ratio (Japanese reimbursement price / US market price)was 2.0-3.5 for coronary stents, 5.9-6.8 for percutaneous transluminal coronary angioplasty catheters, 2.2-3.5 for pacemakers, 1.6-2.5 for mechanical valves, and 3.4-4.7 for oxygenators. The price disparities for cardiovascular devices between Japan and the US were reconfirmed. Japan's healthcare system should establish group-purchasing organizations, promote centers of clinical excellence, and abolish regulation of parallel imports and protectionism under the Japanese Pharmaceutical Affairs Law.

In addition to its potential for redressing physician maldistribution, DME has conferred multiple unexpected educational benefits. In several countries, its recent rise has occurred around the boundaries of traditional medical education practices. Canada has been no exception, with DME proliferating against a backdrop of its longstanding central node, the clinical teaching unit (CTU). The CTU first appeared just over 50 years ago with its position in Canadian health care largely taken-for-granted. Given the increasing prominence of DME, however, it is timely to reconsider what the place of tertiary centre-based practices such as the CTU might be in shifting medical education systems. From a genealogical perspective, it becomes clear that the CTU did not just "happen". Rather, its creation was made possible by multiple interrelated cultural, social, and political changes in Canadian society that, while subtle, are powerfully influential. Making them visible offers a better opportunity to harmonize the benefits of longstanding entities such as the CTU with novel practices such as DME. In so doing, the medical education field may sidestep the pitfalls of investing significant resources that may only produce superficial changes while unwittingly obstructing deeper transformations and improvements. Although this work is refracted through a Canadian prism, reconceptualizing the overall design of medical education systems to take advantage of both tradition and innovation is a persistent challenge across the international spectrum, resistant to tests of time and constraints of context.

    Corrective Action Unit 166 is located in Areas 2, 3, 5, and 18 of the Nevada Test Site, which is 65 miles northwest of Las Vegas, Nevada. Corrective Action Unit (CAU) 166 is comprised of the seven Corrective Action Sites (CASs) listed below: (1) 02-42-01, Cond. Release Storage Yd - North; (2) 02-42-02, Cond. Release Storage Yd - South; (3) 02-99-10, D-38 Storage Area; (4) 03-42-01, Conditional Release Storage Yard; (5) 05-19-02, Contaminated Soil and Drum; (6) 18-01-01, Aboveground Storage Tank; and (7) 18-99-03, Wax Piles/Oil Stain. These sites are being investigated because existing information on the nature and extent of potential contamination is insufficient to evaluate and recommend corrective action alternatives. Additional information will be obtained by conducting a corrective action investigation (CAI) before evaluating corrective action alternatives and selecting the appropriate corrective action for each CAS. The results of the field investigation will support a defensible evaluation of viable corrective action alternatives that will be presented in the Corrective Action Decision Document. The sites will be investigated based on the data quality objectives (DQOs) developed on February 28, 2006, by representatives of the Nevada Division of Environmental Protection; U.S. Department of Energy, National Nuclear Security Administration Nevada Site Office; Stoller-Navarro Joint Venture; and Bechtel Nevada. The DQO process was used to identify and define the type, amount, and quality of data needed to develop and evaluate appropriate corrective actions for CAU 166. Appendix A provides a detailed discussion of the DQO methodology and the DQOs specific to each CAS. The scope of the CAI for CAU 166 includes the following activities: (1) Move surface debris and/or materials, as needed, to facilitate sampling. (2) Conduct radiological surveys. (3) Perform field screening. (4) Collect and submit environmental samples for laboratory analysis to determine if
