    Inspired by photosynthesis, artificial systems for a sustainable energy supply are being designed. Each sequential energy conversion process from light to biomass in natural photosynthesis is a valuable model for an energy collection, transport and conversion system. Notwithstanding the numerous lessons of nature that provide inspiration for new developments, the features of natural photosynthesis need to be reengineered to meet man's demands. This review describes recent strategies toward adapting key lessons from natural photosynthesis to artificial systems. We focus on the underlying material science in photosynthesis that combines photosystems as pivotal functional materials and a range of materials into an integrated system. Finally, a perspective on the future development of photosynthesis mimetic energy systems is proposed.

    1984-01-01

    Originally in 1978 the Special Purpose Materials Task Group was concerned with tritium breeding materials, coolants, tritium barriers, graphite and silicon carbide, ceramics, heat-sink materials, and magnet components. Since then several other task groups have been created, so now the category includes only materials for superconducting magnets and ceramics. For the former application copper-stabilized Nb 3 Sn (Ti) insulated with polyimides will meet the general requirements, so that testing of prototype components is the priority task. Ceramics are required for several critical components of fusion reactors either as dielectrics or as a structural material. Components near the first wall will receive exposures of 5 to 20 MW.year/m"2. Other ceramic applications are well behind the first wall, with lower damage levels. Most insulators operate near room temperature, but ceramic blanket structures may operate up to 1000 0 C. Because of a meager data base, one cannot identify optimum ceramics for structural application; but MgAl 2 O 4 is an attractive dielectric material

    International Nuclear Information System (INIS)

    1980-04-01

    The scope of Special Purpose Materials covers fusion reactor materials problems other than the first-wall and blanket structural materials, which are under the purview of the ADIP, DAFS, and PMI task groups. Components that are considered as special purpose materials include breeding materials, coolants, neutron multipliers, barriers for tritium control, materials for compression and OH coils and waveguides, graphite and SiC, heat-sink materials, ceramics, and materials for high-field (> 10-T) superconducting magnets. It is recognized that there will be numerous materials problems that will arise during the design and construction of large magnetic-fusion energy devices such as the Engineering Test Facility (ETF) and Demonstration Reactor (DEMO). Most of these problems will be specific to a particular design or project and are the responsibility of the project, not the Materials and Radiation Effects Branch. Consequently, the Task Group on Special Purpose Materials has limited its concern to crucial and generic materials problems that must be resolved if magnetic-fusion devices are to succeed. Important areas specifically excluded include low-field (8-T) superconductors, fuels for hybrids, and materials for inertial-confinement devices. These areas may be added in the future when funding permits

    1980-04-01

    Fusion reactor materials problems other than the first-wall and blanket structural materials are investigated. Components that are considered as special purpose materials include breeding materials, coolants, neutron multipliers, barriers for tritium control, materials for compression and OH coils and waveguides, grahite and SiC, heat-sink materials, ceramics, and materials for high-field (>10-T) superconducting magnets. Radiation-induced conductivity of three forms of Al 2 O 3 was measured as a function of ionizing dose rate and temperature. Increases observed are large enough to affect performance of insulators under some fusion reactor operating conditions. Single-crystal MgAl 2 O 4 was shown to exhibit zero swelling when irradiated to approx. 2 x 10 26 n/m 2 at 925 and 1100 K. This ceramic is resistant to nucleation and growth of defect aggregates, and is not characterized by those microstructural conditions which lead to void formation and swelling in Al 2 O 3 . Fracture toughness of single-crystal Al 2 O 3 was significantly increased by elevated-temperature irradiation to approx. 2 x 10 26 n/m 2 , while that for MgAl 2 O 4 and Y 3 Al 5 O 12 showed little or no change. These results show that ceramics can retain their original resistance to crack propagation after high-dose neutron irradiation

    Composite materials have emerged as the materials of choice for increasing the performance and reducing the weight and cost of military, general aviation, and transport aircraft and space launch vehicles. Major advancements have been made in the ability to design, fabricate, and analyze large complex aerospace structures. The recent efforts by Boeing and Airbus to incorporate composite into primary load carrying structures of large commercial transports and to certify the airworthiness of these structures is evidence of the significant advancements made in understanding and use of these materials in real world aircraft. NASA has been engaged in research on composites since the late 1960 s and has worked to address many development issues with these materials in an effort to ensure safety, improve performance, and improve affordability of air travel for the public good. This research has ranged from synthesis of advanced resin chemistries to development of mathematical analyses tools to reliably predict the response of built-up structures under combined load conditions. The lessons learned from this research are highlighted with specific examples to illustrate the problems encountered and solutions to these problems. Examples include specific technologies related to environmental effects, processing science, fabrication technologies, nondestructive inspection, damage tolerance, micromechanics, structural mechanics, and residual life prediction. The current state of the technology is reviewed and key issues requiring additional research identified. Also, grand challenges to be solved for expanded use of composites in aero structures are identified.

    We consider the attributes of a successful engineered material, acknowledging the contributions of composition and processing to properties and performance. We recognize the potential for relevant lessons to be learned from nature, at the same time conceding both the limitations of such lessons and our need to be selective. We then give some detailed attention to the molecular biomimicry of filamentous phage, the process biomimicry of silk and the structure biomimicry of hippopotamus 'sweat', in each case noting that the type of lesson now being learned is not the same as the potential lesson that originally motivated the study.

  17. Alternative routes for highway shipments of radioactive materials and lessons learned from state designations

    International Nuclear Information System (INIS)

    1990-07-01

    Pursuant to the Hazardous Materials Transportation Act (HMTA), the Department of Transportation (DOT) has promulgated a comprehensive set of regulations regarding the highway transportation of high-level radioactive materials. These regulations, under docket numbers HM-164 and HM-164A, establish interstate highways as the preferred routes for the transportation of radioactive materials within and through the states. The regulations also provide a methodology by which a state may select altemative routes. First, the state must establish a ''state routing agency'', defined as an entity authorized to use the state legal process to impose routing requirements on carriers of radioactive material (49 CFR 171.8). Once identified, the state routing agency must select routes in accordance with DOTs Guidelines for Selecting Preferred Highway Routes for Large Quantity Shipments of Radioactive Materials or an equivalent routing analysis. Adjoining states and localities should be consulted on the impact of proposed alternative routes as a prerequisite of final route selection. Lastly, the states must provide written notice to DOT of any alternative route designation before the routes are deemed effective. The purpose of this report is to discuss the ''lessons learned'' by the five states within the southern region that have designated alternative or preferred routes under the regulations of the Department of Transportation (DOT) established for the transportation of radioactive materials. The document was prepared by reviewing applicable federal laws and regulations, examining state reports and documents and contacting state officials and routing agencies involved in making routing decisions. In undertaking this project, the Southern States Energy Board hopes to reveal the process used by states that have designated alternative routes and thereby share their experiences (i.e., lessons learned) with other southern states that have yet to make designations

    Cremaldi, Joseph C

    2018-01-01

    Healing is an intrinsic ability in the incredibly biodiverse populations of the plant and animal kingdoms created through evolution. Plants and animals approach healing in similar ways but with unique pathways, such as damage containment in plants or clotting in animals. After analyzing the examples of healing and defense mechanisms found in living nature, eight prevalent mechanisms were identified: reversible muscle control, clotting, cellular response, layering, protective surfaces, vascular networks or capsules, exposure, and replenishable functional coatings. Then the relationship between these mechanisms, nature’s best (evolutionary) methods of mitigating and healing damage, and existing technology in self-healing materials are described. The goals of this top-level overview are to provide a framework for relating the behavior seen in living nature to bioinspired materials, act as a resource to addressing the limitations/problems with existing materials, and open up new avenues of insight and research into self-healing materials.

  3. Public participation and environmental impact assessment: Purposes, implications, and lessons for public policy making

    International Nuclear Information System (INIS)

    O'Faircheallaigh, Ciaran

    2010-01-01

    In recent years the need to enhance public participation in Environmental Impact Assessment (EIA), and the efficacy of alternative mechanisms in achieving this goal, have been central themes in the EIA literature. The benefits of public participation are often taken for granted, and partly for this reason the underlying rationale for greater public participation is sometimes poorly articulated, making it more difficult to determine how to pursue it effectively. The reasons for seeking public participation are also highly diverse and not always mutually consistent. There has been limited analysis of the implications of different forms and degrees of public participation for public decision making based on EIA, and little discussion of how experience with public participation in EIA relates to debates about participation in policy making generally. This paper distinguishes various purposes for public participation in EIA, and discusses their implications for decision making. It then draws on some general models of public participation in policy making to consider how approaches to participation in EIA can be interpreted and valued, and asks what EIA experience reveals about the utility of these models. It argues that the models pay insufficient attention to the interaction that can occur between different forms of public participation; and to the fact that public participation raises issues regarding control over decision making that are not subject to resolution, but must be managed through ongoing processes of negotiation.

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

    International Nuclear Information System (INIS)

    Was, Gary S.

    2007-01-01

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

    1990-01-01

    A very accurate accountability of nuclear materials is required throughout the industrial nuclear fuel cycle for technical reasons and safety purposes but also for commercial, physical protection and safeguards objectives. The present note intends to illustrate with a few samples the performance presently achieved and the major questions which the analysts are facing in these areas. The examples taken concern the accountability of feed and product materials at LWR nuclear fuel fabrication plants and spent fuel reprocessing plants. They were selected because they constitute major components of the flow and inventory of the nuclear fuel materials at key measurement points in nuclear industry. The factors limiting the quality of the assays and accountability of these industrial materials and some observations regarding the need and use of reference materials and quality control programmes in support of accurate accounting are presented. 7 refs

    Grabowski, L.; Baier, A.; Sobek, M.

    2017-08-01

    The casting of metal materials is widely known but the molding of composite polymer materials is not well-known method still. The initial choice of method for producing composite bodies was the method of casting of PDCPD material. For purpose of performing casting of polymer composite material, a special mold was made. Firstly, the 3D printed, using PLA material, mold was used. After several attempts of casting PDCPD many problems were encountered. The second step was to use mold milled from a firm and dense isocyanate foam. After several attempts research shown that this solution is more resistant to high-temperature peak, but this material is too fragile to use it several times. This solution also prevents mold from using external heating, which can be necessary for performing correct molding process. The last process was to use the aluminum mold, which is dedicated to PDCPD polymer composite, because of low adhesiveness. This solution leads to perform correct PDCPD polymer composite material injection. After performing casting operation every PDCPD testing samples were tested. These results were compared together. The result of performed work was to archive correct properties of injection of composite material. Research and results were described in detail in this paper.

    1987-01-01

    Recent developments in the formulation of detection capability and accuracy criteria for bioassay measurements will be interpreted and adapted to provide similar criteria for the measurement of air concentrations of radioactive material for radiation protection purposes. Considerations of accuracy will be related to the known variability of measurement processes, as well as the uncertainties in the calculated limits of intake that serve as the basis of regulatory and voluntary standards of practice. Formulations and criteria will be presented for minimum detection amounts (MDA) and precision and bias of measurements for radiation protection purposes. 17 references

  16. Use of Nuclear Material Accounting and Control for Nuclear Security Purposes at Facilities. Implementing Guide

    International Nuclear Information System (INIS)

    2015-01-01

    Nuclear material accounting and control (NMAC) works in a complementary fashion with the international safeguards programme and physical protection systems to help prevent, deter or detect the unauthorized acquisition and use of nuclear materials. These three methodologies are employed by Member States to defend against external threats, internal threats and both state actors and non-state actors. This publication offers guidance for implementing NMAC measures for nuclear security at the nuclear facility level. It focuses on measures to mitigate the risk posed by insider threats and describes elements of a programme that can be implemented at a nuclear facility in coordination with the physical protection system for the purpose of deterring and detecting unauthorized removal of nuclear material

    Microbubbles with diameters ranging from a few micrometers to tens of micrometers have garnered significant attention in various applications including food processing, water treatment, enhanced oil recovery, surface cleaning, medical purposes, and material preparation fields with versatile functionalities. A variety of techniques have been developed to prepare microbubbles, such as ultrasonication, excimer laser ablation, high shear emulsification, membrane emulsification, an inkjet printing method, electrohydrodynamic atomization, template layer-by-layer deposition, and microfluidics. Generated bubbles should be immediately stabilized via the adsorption of stabilizing materials (e.g., surfactants, lipids, proteins, and solid particles) onto the gas-liquid interface to lower the interfacial tension. Such adsorption of stabilizers prevents coalescence between the microbubbles and also suppresses gas dissolution and resulting disproportionation caused by the presence of the Laplace overpressure across the gas-liquid interface. Herein, we comprehensively review three important topics of microbubbles: stabilization, fabrication, and applications.

    University 101 courses are typically designed to help incoming first-year undergraduate students to adjust to the university, develop a better understanding of the college environment, and acquire essential academic success skills. Why are we offering a special Boiler and HRSG Tube Failures PPChem 101? The answer is simple, yet very conclusive: - There is a lack of knowledge on the identification of tube failure mechanisms and for the implementation of adequate counteractions in many power plants, particularly at industrial power and steam generators. - There is a lack of knowledge to prevent repeat tube failures. The vast majority of BTF/HTF have been, and continue to be, repeat failures. It is hoped that the information about the failure mechanisms of BTF supplied in this course will help to put plant engineers and chemists on the right track. The major goal of this course is the avoidance of repeat BTF. This ninth lesson is focused on Oxide Growth and Exfoliation of Materials in Steam Tubing. (orig.)

For this reason, English for Academic Purposes has been conducted in the first year of college level for many years. Unfortunately, although many Asian countries including Indonesia have run the EAP course, the output is that there are still many Indonesian students who do not meet the vocabulary size and syntactic complexity that are expected while their learning process in the university. This results lower grades that they have in their assignments. Therefore, the recent study is aimed at evaluating the reading materials of EAP, especially in measuring the syntactic complexity containing in the texts as it is strongly believed in

    Three ceramic, reusable surface insulation materials and two borosilicate glass coatings were used in the fabrication of tiles for the Space Shuttle orbiters. Approximately 77,000 tiles were made from these materials for the first three orbiters, Columbia, Challenger, and Discovery. Lessons learned in the development, scale up to production and manufacturing phases of these materials will benefit future production of ceramic reusable surface insulation materials. Processing of raw materials into tile blanks and coating slurries; programming and machining of tiles using numerical controlled milling machines; preparing and spraying tiles with the two coatings; and controlling material shrinkage during the high temperature (2100-2275 F) coating glazing cycles are among the topics discussed.

    The use of ionizing radiation in the development of natural and synthetic polymers for agricultural purposes has proven to be successful. Polysaccharides such as chitosan and sodium alginate are easily degraded through ionizing radiation which is considered to be a safe, clean, and an environment-friendly method. As a result, different kinds of biologically active fragments possessing growth promotion properties for plant performance and antimicrobial activities against pathogenic microorganisms for food preservation were obtained. Several factors such as preparation conditions, quality of the new materials, safety of the materials especially where the environment is concerned, and economic feasibility and production cost have been studied in its aim to commercialize the products. The required dose for degradation of soluble polysaccharide is relatively low when compared with that of solid polysaccharides. From the economic point of view, the choice to degrade polysaccharide with the use of viscous polysaccharide solutions containing 0.5–1 wt% oxidizing agent such as H{sub 2}O{sub 2} is necessary to decrease the dose required for degradation in the range of 20–30 kGy. Average molecular weights (MW) as well as molecular weights distributions were accurately determined by using different techniques like gel permeation chromatography (GPC) and viscometer. Large scale field studies of degraded polysaccharide materials as a growth promoter or an elicitor for different crops like wheat, faba bean, zea maze, and other vegetables and fruits (e.g. tomato, hot pepper, and banana crops) have been carried out. It was found that the treatment with low MW alginate of plants such as wheat increased its productivity by 25–30%, improved the quality of the crop, and enhanced the capability of wheat seeds to be used for long-term cultivation. The use of irradiated polysaccharides in stimulating defense reactions against some diseases in some plants was studied. Sodium alginates

    In a September 1993 address to the United Nations General Assembly, President Clinton announced a new nonproliferation and export control policy that established a framework for US efforts to prevent the proliferation of weapons of mass destruction. The new policy proposed that the US undertake a comprehensive approach to the growing accumulation of fissile material. One of the key elements was for the US to support a special nuclear materials (SNM) multilateral convention prohibiting the production of highly enriched uranium (HEU) or plutonium for nuclear explosives purposes or outside of international safeguards. This policy is often referred to as the President's Cutoff Initiative or the Fissile Material Cutoff Treaty (FMCT). Because both the US Department of Energy (DOE) and foreign reprocessing facilities similar to PUREX will likely to be inspected under a FMCT, the DOE Office of Arms Control and Nonproliferation, Negotiations and Analysis Division (DOE/NN-41) tasked Pacific Northwest Laboratory (PNL) to perform an information gathering exercise, the PUREX Exercise, using the Plutonium-Uranium Extraction (PUREX) Plant located on the Hanford Site in Washington State. PUREX is a former production reactor fuel reprocessing plant currently undergoing a transition to a ''decontamination and decommissioning (D ampersand D) ready'' mode. The PUREX Exercise was conducted March 29--30, 1994, to examine aspects of the imposition of several possible cutoff regimes and to study verification of non-production of SNM for nuclear weapons purposes or outside of safeguards. A follow-up activity to further examine various additional verification regimes was held at Los Alamos National Laboratory (LANL) on May 10, 1994

    Central Control Laboratory (CCL) of the Nuclear Research Institute was charged with the control of nuclear materials in CSSR within the framework of the safeguards system. The CCL has been directed by the Department of nuclear safety and safeguards of CAEC according to a long-term plan, elaborated for controlling nuclear material in CSSR. The CCL has mainly been performing independent, rapid, accurate, and reliable analyses of nuclear materials, using destructive as well as non-destructive methods; the analyses of samples taken in MBA's in CSSR are mentioned, concerning the determinations of U, Pu, and Th contents, isotopic compositions of U and Pu, and burn up. The results of the analyses have served for the material and isotopic balances of fissile materials and the control of fuel reprocessing under laboratory conditions. The methods for sampling and sample transport as well as sample treatment before the analysis are described. The experience is given, obtained at CCL during a routine application of chemical methods for highly precise determinations of U, Pu, and Th (titration-based methods), mass-spectrometric determinations of U and Pu (isotopic composition, IDA using 233 U and 242 Pu), and burn-up determinations based on radioactive fissile products (Cs, Ru, Ce) and stable Nd isotopes. Some non-destructive methods for controlling nuclear materials (passive gamma-spectrometry) are discussed

    In accord with as-low-as-reasonably-achievable and good-manufacturing-practice concepts, the present study evaluated the efficiency of radioactivity decontamination of materials commonly used in laboratory surfaces and whether solvent spills on these materials affect the findings. Four materials were evaluated: stainless steel, a surface comprising one-third acrylic resin and two-thirds natural minerals, an epoxy cover, and vinyl-based multipurpose flooring. Radioactive material was eluted from a (99)Mo/(99m)Tc generator, and samples of the surfaces were control-contaminated with 37 MBq (100 μL) of this eluate. The same procedure was repeated with samples of surfaces previously treated with 4 solvents: methanol, methyl ethyl ketone, acetone, and ethanol. The wet radioactive contamination was allowed to dry and then was removed with cotton swabs soaked in soapy water. The effectiveness of decontamination was defined as the percentage of activity removed per cotton swab, and the efficacy of decontamination was defined as the total percentage of activity removed, which was obtained by summing the percentages of activity in all the swabs required to complete the decontamination. Decontamination using our protocol was most effective and most efficacious for stainless steel and multipurpose flooring. Moreover, treatment with common organic solvents seemed not to affect the decontamination of these surfaces. Decontamination of the other two materials was less efficient and was interfered with by the organic solvents; there was also great variability in the overall results obtained for these other two materials. In expanding our laboratory, it is possible for us to select those surface materials on which our decontamination protocol works best. © 2014 by the Society of Nuclear Medicine and Molecular Imaging, Inc.

    The growing industry of polymer and composite materials is facing new challenges posed by the automotive industry. In this industry, traditional materials such as steel and aluminum are widely replaced with plastic materials, including polymers. In the past, such behavior concerned design and interior elements, but more and more often plastics are used in the case of load-bearing elements, i.e. those that require high strength and durability nowadays. This kind of materials are also often used in safety systems or driver assistance systems. Therefore, the aim of the activities described in this article are to carry out an innovative process of injection of cold polymeric material, PDCPD (Polidicyclopentadiene), polymerizing with the use of Metathesis reaction, which in 2005 was awarded the Nobel Prize. This injection applies to the worm gear components of the system, supports the power steering system of the passenger car. Also the process of selecting the appropriate parameters to carry out this process, guaranteeing the best quality of the obtained elements is necessary. The aim of the activities was to achieve a fully useful power steering support system, using a polymer body, which is replacing the aluminum. These activities were aimed at reducing the costs and weight of the final product. The injection process and the way to achieve the finished product were carried out in an innovative way, never used in industry before.

    Full Text Available Chinese lacquer (urushi is an ancient natural finishing material obtained from the sap of the lacquer trees (Rhus vernicifera. This has been used for millennia to protect and decorate furniture and various artefacts made of wood or other materials. Lacquered objects are important components of Chinese and world cultural heritage and their conservation imposes a good knowledge and understanding of the material and traditional techniques. This paper presents basic information on the Chinese lacquer as material and lacquering techniques in their historic evolution during different dynasties. The experimental part looked at the physical properties of raw urushi lacquer, respectively aspect, solids content and miscibility with different solvents. A limited compatibility with white spirit as potential thinner was demonstrated. Furthermore, the microstructure of the cured film and characteristic chemical features of raw urushi lacquer as liquid and cured film were investigated. The cured film of raw urushi presents a characteristic microstructural pattern. FTIR spectroscopy revealed a partial oxidation and polymerization following processing by Kuromisation. The further curing accentuated these changes, visible as a decrease of hydroxyl absorptions bands (3400 and 1360cm-1 occurring in parallel with an increase of carbonyl band (1740cm-1 . A strong decrease of the absorption band at 1270cm-1 , which nearly disappears for the cured film, was also observed

    The State System of Accounting and Control of Nuclear Material (SSAC) in South Africa comprises a State Inspectorate, Technical Support and Safeguards Information Systems (SIS). SIS is responsible for the quality control and assurance of the Nuclear Material Reports, Additional Protocol declarations and submission to the IAEA. Monthly reports are received from the facilities where inventory changes took place. Reports are prepared according to a Quality Management Document: Instruction for the Completion of Nuclear Material Accounting Reports. The inventory changes are reported on spreadsheets developed for our system. The Inventory Change Reports (ICR) and General Ledgers (GL) are compared line by line to check for discrepancies, which will be noted on a Control Sheet. The form will be sent to the relevant facility to notify them of corrections needed. The corrected reports will be re-submitted to SIS. A spreadsheet is used in the verification process with columns for all material categories and inventory change codes. The ICR totals of all inventory changes can be reconciled with the GL values. If all the entries are correct the nuclear material totals should be the same as on the GL. The facility file is checked by the State Inspector responsible for the specific facility as a second round of quality control. The inspector is required to sign the Control Sheet to confirm the completeness and correctness of the reports. The Excel data is then converted into a text (.txt) file, encrypted and then submitted electronically to the Agency. This paper will present all the steps involved in ensuring the correctness of the reports and the quality control measures in detail used by the South Africa SSAC. (author)

    Natural laminar flow is one of the challenging aims of the current aerospace research. Main reasons for the aerodynamic transition from laminar into turbulent flow focusing on the airfoil-structure is the aerodynamic shape and the surface roughness. The Institute of Composite Structures and Adaptive Systems at the German Aerospace Center in Braunschweig works on the optimization of the aerodynamic-loaded structure of future aircrafts in order to increase their efficiency. Providing wing structures suited for natural laminar flow is a step towards this goal. Regarding natural laminar flow, the structural design of the leading edge of a wing is of special interest. An approach for a gap-less leading edge was developed to provide a gap- and step-less high quality surface suited for natural laminar flow and to reduce slat noise. In a national project the first generation of the 3D full scale demonstrator was successfully tested in 2010. The prototype consists of several new technologies, opening up the issue of matching the long and challenging list of airworthiness requirements simultaneously. Therefore the developed composite structure was intensively tested for further modifications according to meet requirements for abrasion, impact and deicing basically. The former presented structure consists completely of glass-fiber-prepreg (GFRP-prepreg). New functions required the addition of a new material-mix, which has to fit into the manufacturing-chain of the composite structure. In addition the hybrid composites have to withstand high loadings, high bending-induced strains (1%) and environmentally influenced aging. Moreover hot-wet cycling tests are carried out for the basic GFRP-structure in order to simulate the long term behavior of the material under extrem conditions. The presented paper shows results of four-points-bending-tests of the most critical section of the morphing leading edge device. Different composite-hybrids are built up and processed.

In the present work, the effects of iron (III) complex with tetraphenylporphyrin and its influence on bactericidal and antibacterial properties of the ultrathin PHB fibers were investigated.

  19. Forensic DNA Phenotyping: Predicting human appearance from crime scene material for investigative purposes.

    Science.gov (United States)

    Kayser, Manfred

    2015-09-01

    Forensic DNA Phenotyping refers to the prediction of appearance traits of unknown sample donors, or unknown deceased (missing) persons, directly from biological materials found at the scene. "Biological witness" outcomes of Forensic DNA Phenotyping can provide investigative leads to trace unknown persons, who are unidentifiable with current comparative DNA profiling. This intelligence application of DNA marks a substantially different forensic use of genetic material rather than that of current DNA profiling presented in the courtroom. Currently, group-specific pigmentation traits are already predictable from DNA with reasonably high accuracies, while several other externally visible characteristics are under genetic investigation. Until individual-specific appearance becomes accurately predictable from DNA, conventional DNA profiling needs to be performed subsequent to appearance DNA prediction. Notably, and where Forensic DNA Phenotyping shows great promise, this is on a (much) smaller group of potential suspects, who match the appearance characteristics DNA-predicted from the crime scene stain or from the deceased person's remains. Provided sufficient funding being made available, future research to better understand the genetic basis of human appearance will expectedly lead to a substantially more detailed description of an unknown person's appearance from DNA, delivering increased value for police investigations in criminal and missing person cases involving unknowns.

    The problem of water pollution is of a great concern. Adsorption is one of the most efficient techniques for removing noxious heavy metals from the solvent phase. This paper presents a detailed information and review on the adsorption of noxious heavy metal ions from wastewater effluents using various adsorbents - i.e., conventional (activated carbons, zeolites, clays, biosorbents, and industrial by-products) and nanostructured (fullerenes, carbon nanotubes, graphenes). In addition to this, the efficiency of developed materials for adsorption of the heavy metals is discussed in detail along with the comparison of their maximum adsorption capacity in tabular form.

    2014-01-01

    In many regards the study of materials and minerals by powder diffraction techniques are complimentary, with techniques honed in one field equally applicable to the other. As a long-time materials researcher many of the examples are of techniques developed for materials analysis applied to minerals. However in a couple of cases the study of new minerals was the initiation into techniques later used in materials-based studies. Hopefully they will show that the study of new minerals structures can provide opportunities to add new methodologies and approaches to future problems. In keeping with the AXAA many of the examples have an Australian connection, the materials ranging from organics to battery materials.

    2017-04-01

    Biocompatibility of dental materials has gained increasing interest during recent decades. Meanwhile, legal regulations and standard test procedures are available to evaluate biocompatibility. Herein, these developments will be exemplarily outlined and some considerations for the development of novel materials will be provided. Different aspects including test selection, release of substances, barriers, tissue healing, antibacterial substances, nanoparticles and environmental aspects will be covered. The provided information is mainly based on a review of the relevant literature in international peer reviewed journals, on regulatory documents and on ISO standards. Today, a structured and systematic approach for demonstrating biocompatibility from both a scientific and regulatory point of view is based on a clinical risk assessment in an early stage of material development. This includes the analysis of eluted substances and relevant barriers like dentin or epithelium. ISO standards 14971, 10993, and 7405 specify the modes for clinical risk assessment, test selection and test performance. In contact with breached tissues, materials must not impair the healing process. Antibacterial effects should be based on timely controllable substances or on repellant surfaces. Nanoparticles are produced by intraoral grinding irrespective of the content of nanoparticles in the material, but apparently at low concentrations. Concerns regarding environmental aspects of mercury from amalgam can be met by amalgam separating devices. The status for other materials (e.g. bisphenol-A in resin composites) needs to be evaluated. Finally, the public interest for biocompatibility issues calls for a suitable strategy of risk communication. A wise use of the new tools, especially the clinical risk assessment should aim at preventing the patients, professionals and the environment from harm but should not block the development of novel materials. However, biocompatibility must always be

  6. Safety of the Transport of Radioactive Materials for Civilian Use in France. Lessons learned by IRSN from analysis of significant events reported in 2012 and 2013

    International Nuclear Information System (INIS)

    2015-01-01

    Every two years since 2008, IRSN has published in a report the lessons learnt from its analysis of significant events involving the transport of radioactive materials for civilian purposes in France. Each year in France, some 770,000 shipments of radioactive materials for civilian use are done by road, railway, inland waterway, sea and air. For 2012 and 2013, the report did not find evidence of degradation compared with previous years, particularly for industrial activities in the nuclear power industry, which raise the most significant safety issues. Since 1999, approximately a hundred events are reported each year, which represents, on average, one event per 10,000 packages transported. IRSN notes that none of the events that occurred over the two years had an impact on public health or environmental protection. Events involving a defect in the closure of spent fuel shipping packages and deviations concerning the content of the packages, which had increased in 2010 and 2011, are now down. It would seem to confirm that the organizational measures implemented by those sending the packages have had a positive impact. Previous trends which brought to light failures in the preparation of packages and their handling, in particular in the medical sector, have been confirmed. Even if most of the packages concerned contain low levels of radioactivity, recurrence of these events confirms the value of implementing appropriate preventive actions on the part of the companies involved. Lastly, descriptions of several typical events that occurred in 2012 and 2013 provide illustrations of the analyses that were performed on actual cases

  7. Towards socio-material approaches in simulation-based education: lessons from complexity theory.

    Science.gov (United States)

    Fenwick, Tara; Dahlgren, Madeleine Abrandt

    2015-04-01

    Review studies of simulation-based education (SBE) consistently point out that theory-driven research is lacking. The literature to date is dominated by discourses of fidelity and authenticity - creating the 'real' - with a strong focus on the developing of clinical procedural skills. Little of this writing incorporates the theory and research proliferating in professional studies more broadly, which show how professional learning is embodied, relational and situated in social - material relations. A key concern for medical educators concerns how to better prepare students for the unpredictable and dynamic ambiguity of professional practice; this has stimulated the movement towards socio-material theories in education that address precisely this question. Among the various socio-material theories that are informing new developments in professional education, complexity theory has been of particular importance for medical educators interested in updating current practices. This paper outlines key elements of complexity theory, illustrated with examples from empirical study, to argue its particular relevance for improving SBE. Complexity theory can make visible important material dynamics, and their problematic consequences, that are not often noticed in simulated experiences in medical training. It also offers conceptual tools that can be put to practical use. This paper focuses on concepts of emergence, attunement, disturbance and experimentation. These suggest useful new approaches for designing simulated settings and scenarios, and for effective pedagogies before, during and following simulation sessions. Socio-material approaches such as complexity theory are spreading through research and practice in many aspects of professional education across disciplines. Here, we argue for the transformative potential of complexity theory in medical education using simulation as our focus. Complexity tools open questions about the socio-material contradictions inherent in

    The structures and properties of a new class of composite materials, containing a predominantly high volume fraction ceramic or glass phase, combined with minor organic (adhesive) phases, have been studied. These composites have unusual combinations of mechanical properties, such as stiffness, strength, and toughness. They are based on the architecture of a rigid natural material, the nacre structure, such as those found in the shells of the abalone Haliotis rufescens, and those of other mollusk shells. The mechanisms underlying these properties have also been studied. Analogs (utilizing high-performance engineering materials), that mimic many of the mechanisms underlying those superior combinations of properties, have been built. The results of the foregoing investigations are discussed. It was found that the toughness of segmented composite beams which have high volume fractions of ceramic (89 v / o) exceeded those of continuous layered beams, as well as the monolithic ceramic (alumina) on which they are based.

    Full Text Available Material transfer agreements exist to facilitate the exchange of materials and associated data between researchers as well as to protect the interests of the researchers and their institutions. But this dual mandate can be a source of frustration for researchers, creating administrative burdens and slowing down collaborations. We argue here that in most cases in pre-competitive research, a simple agreement would suffice; the more complex agreements and mechanisms for their negotiation should be reserved for cases where the risks posed to the institution and the potential commercial value of the research reagents is high.

  13. Physico-Chemical Alternatives in Lignocellulosic Materials in Relation to the Kind of Component for Fermenting Purposes

    Directory of Open Access Journals (Sweden)

    Alberto Coz

    2016-07-01

    Full Text Available The complete bioconversion of the carbohydrate fraction is of great importance for a lignocellulosic-based biorefinery. However, due to the structure of the lignocellulosic materials, and depending basically on the main parameters within the pretreatment steps, numerous byproducts are generated and they act as inhibitors in the fermentation operations. In this sense, the impact of inhibitory compounds derived from lignocellulosic materials is one of the major challenges for a sustainable biomass-to-biofuel and -bioproduct industry. In order to minimise the negative effects of these compounds, numerous methodologies have been tested including physical, chemical, and biological processes. The main physical and chemical treatments have been studied in this work in relation to the lignocellulosic material and the inhibitor in order to point out the best mechanisms for fermenting purposes. In addition, special attention has been made in the case of lignocellulosic hydrolysates obtained by chemical processes with SO2, due to the complex matrix of these materials and the increase in these methodologies in future biorefinery markets. Recommendations of different detoxification methods have been given.

    Clay minerals are layered materials with a number of peculiar properties, which find many relevant applications in various industries. Since they are easily found everywhere, they are particularly attractive due to their economic viability. In the cosmetic industry, clay minerals are often used as excipients to stabilize emulsions or suspensions and to modify the rheological behavior of these systems. They also play an important role as adsorbents or absorbents, not only in cosmetics but also in other industries, such as pharmaceuticals. This reviewer believes that since this manuscript is presented as covering topical applications that include pharmaceuticals, some types of clay minerals should be considered as a potential material to be used as drug delivery systems. We review several applications of clay minerals to dermocosmetic products, relating them to the underlying properties of these materials and exemplifying with a number of clay minerals available in the market. We also discuss the use of clay minerals in topically-applied products for therapeutic purposes, specially for skin treatment and protection. Copyright © 2017 Elsevier B.V. All rights reserved.

    The paper sets forth the basic principles underlying nuclear material accounting at nuclear power plants with WWER-440 reactors. It briefly describes the general structure and individual units in a program for computerized accounting. The use of this program is illustrated by the actual accounting data from the fifth unit of the Novovoronezh nuclear power station. The NUMIS program seems to be of interest both for the purposes of IAEA safeguards and for nuclear power plant operators in countries where power plants with WWER-440 reactors subject to IAEA safeguards are either in operation or under construction. The research in question was conducted initially under an IAEA research contract; the system is now being developed further and tested under the IAEA-USSR technical and scientific co-operation programme on safeguards.

    Full Text Available In the information era that we experience today, there is a rapid change in the methods, techniques and materials used for education and teaching. The usage of information and communication technology-assisted teaching materials are becoming more commonplace. Parallel to these developments, the Ministry of National Education took steps to develop IT substructures of all schools in the country and implemented many projects. The purpose of this study is to determine whether or not the multimedia lesson content used by teachers affect effective learning. This study is a qualitative study, conducted with 45 teachers working in primary schools during the 2011-2012 academic year. According to the study findings, participants believe that using multimedia lesson content during lectures increases student motivation, makes students more curious and interested, and think that using multimedia lesson content has positive effects.

  20. Working material. IAEA seismic safety of nuclear power plants. International workshop on lessons learned from strong earthquake

    2008-08-01

    The International Workshop on Lessons Learned from Strong Earthquake was held at Kashiwazaki civic plaza, Kashiwazaki, Niigata-prefecture, Japan, for three days in June 2008. Kashiwazaki-Kariwa NPP (KK-NPP) is located in the city of Kashiwazaki and the village of Kariwa, and owned and operated by Tokyo Electric Power Company Ltd. (TEPCO). After it experienced the Niigata-ken Chuetsu-oki earthquake in July 2007, IAEA dispatched experts' missions twice and held technical discussions with TEPCO. Through such activities, the IAEA secretariat and experts obtained up-dated information of plant integrity, geological and seismological evaluation and developments of the consultation in the regulatory framework of Japan. Some of the information has been shared with the member states through the reports on findings and lessons learned from the missions to Japan. The international workshop was held to discuss and share the information of lessons learned from strong earthquakes in member states' nuclear installations. It provided the opportunity for participants from abroad to share the information of the recent earthquake and experience in Japan and to visit KK-NPP. And for experts in Japan, the workshop provided the opportunity to share the international approach on seismic-safety-related measures and experiences. The workshop was organised by the IAEA as a part of an extra budgetary project, in cooperation with OECD/NEA, hosted by Japanese organisations including Nuclear and Industrial Safety Agency (NISA), Nuclear Safety Commission (NSC), and Japan Nuclear Energy Safety Organization (JNES). The number of the workshop participants was 70 experts from outside Japan, 27 countries and 2 international organisations, 154 Japanese experts and 81 audience and media personnel, totalling to 305 participants. The three-day workshop was open to the media including the site visit, and covered by NHK (the nation's public broadcasting corporation) and nation-wide and local television

    2003-01-01

    Full Text Available Background: Lesson planning has a distinct role in enhancing education quality, as well as maintaining the friendly and dynamic atmosphere of the academic environment and increasing student's initiatives for achieving better educational attainments. Lesson planning is a process for defining the goals, understanding the needs, and specifying available tools and possible limitations. Lesson planning is a written description of this process, which shows the materials, the route, the time, and the place of instructions, as well as a method for evaluating students. Purpose: to identify the attitudes of Semnan University of Medical Sciences (SUMS on lesson planning. Methods: Fifty-three faculty members of the SUMS participated in this study. A questionnaire was used, which contained 8 demographic questions, and 24 r questions for identification the faculty members' attitude. Questionnaires were distributed among the faculty members in sealed envelopes, without denoting their names. The questionnaires were gathered after being completed. Results were analyzed by calculating the mean, standard deviation, absolute and relative frequencies, and using Chi-square and Fischer exact test at the level of 5%. Results: II was shown that 88% of faculty members favoured lesson planning before the beginning of the semester. But they found lesson planning a difficult task, because of their heavy workload. Of the faculty members, 60.4% organized their teaching classes according to a designed lesson plan, and believed that it did affect the quality of their teaching, but 49.1% disagreed with distributing the designed lesson plan among the students. Discussion: Although professor favoured lesson planning and find it necessary to work according to such a plan, workload and lack of knowledge are defined as two main obstacles in doing so. It is believed that by decreasing the professor's workload and provision of lesson planning workshops, these problems could be solved

    One of the most common procedures used in determining the amount of nuclear material contained in solutions consists of first measuring the volume and the density of the solution, and then determining the concentrations of this material. This presentation will focus on errors generated at the process lime in the measurement of volume and density. These errors and their associated uncertainties can be grouped into distinct categories depending on their origin: those attributable to measuring instruments; those attributable to operational procedures; variability in measurement conditions; errors in the analysis and interpretation of results. Possible errors sources, their relative magnitudes, and an error propagation rationale are discussed, with emphasis placed on bases and errors of the last three types called systematic errors [ru

    2014-05-01

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

    The present paper considers two gain GRIN media, characterized by a complex parabolic and hyperbolic secant refractive index profile, for the design of uniform beam shaper systems. A general condition for beam shaping is obtained from the equation describing the evolution of the half-width of a plane Gaussian beam in the GRIN media. The simulation of the irradiance evolution of an input plane Gaussian beam—operating at 575 nm and beam waist radius of 0.45 mm—in each material is shown, in order to examine the beam shaping quality in terms of thickness of the active GRIN media and input beam wavelength.

  9. Western and WWER materials investigations - past lessons, present achievements and future trends for fuel rod cladding and fuel assembly structure

    International Nuclear Information System (INIS)

    Weidinger, H.

    2001-01-01

    The paper gives a detailed overview of Western and WWER materials used in nuclear fuel manufacturing industry. The status of technical experience with regard to design, fabrication and particular in-pile behavior is described and compared for material of major importance for PWR and WWER fuel. In particular Zr-base alloys for cladding tubes, spacer grids and guide thimbles are considered. In addition spacer spring materials are also discussed. The paper shows that during the last decade a considerable diversification of different Zr materials occurred in Western PWR fuel, while for WWER fuel the focus is still on the classical Zr1%Nb material. Corrosion and hydrogen uptake as well as the dimensional behavior (creep and growth) of all presently relevant Zr-based materials is described in detail. For spacer springs Zr-based and Ni-based materials are considered. For this application spring force relaxation is the most important issue. The paper shows that the focus of consideration is typically different for PWR and WWER fuel materials. While for PWR fuel mainly corrosion and hydrogen uptake is most important and design limiting, for WWER fuel the focus of interests is with mechanical strength. The main reason for this significant difference is that the corrosive environment is typically different for PWR and WWER cores

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

  12. Incidents in transport of radioactive materials for civil use: IRSN draws lessons from events reported between 1999 and 2007

    Some 900,000 packages of radioactive materials for civil use are transported each year in France. The great majority of these shipments involve radioactive materials used in the fields of medicine, pharmaceuticals, industry or property. Transport of radioactive materials linked to the nuclear fuel cycle actually represents only 15% of transport. A great variety of material is transported, differing in weight (from a few grams to tens of tons), form, activity and packaging. The associated risks are also different: radioactive contamination, external exposure to ionising radiation, chemical risk etc. In its role of technical support to safety and radioprotection authorities, IRSN's mission is to assess the design, manufacturing, testing and use of packaging and transport systems. The Institute is also involved in the management and analysis of events that occur during transport of radioactive materials. To assist with this, the IRSN manages a database which lists reported deviations, anomalies, incidents and accidents (known in a generic way as 'events') relating to transport. With an aim of reduction of the risks related to transport, the feedback resulting from the thorough analysis of the notified events is capitalized by IRSN, just as the feedback of the assessments of the safety analysis reports of the various package designs. Based on these feedbacks, IRSN proposes axes of improvement relating to package designs and transport operations, and regulatory evolutions, as well as priority topics for the inspections carried out by the French Nuclear safety authority (ASN). The IRSN has carried out a transversal analysis of all events in transport of radioactive materials that occurred in France from 1999 to 2007 as listed in its database (i.e. 901 events). For each event, some 70 parameters have been recorded from the analysis of the notifications and reports of the events, transmitted by the operators (type of event, type of package, level on the INES scale).

    Full text: SCK CEN is dismantling its 11 MWe PWR reactor. The reactor was shutdown in 1987 after 25 years of operation and the dismantling started in 1990. For the management of the low radioactive materials, we apply a strategy promoting the minimisation of the production of radioactive waste and hence the maximisation of the production of recycled materials while keeping the costs as low as possible. The recycled materials are either reused in the non- nuclear industry as raw materials (metal scrap industry or building industry for the concrete) or recycled in the nuclear industry for specific applications (reuse of metals for fabrication of shielding, potential reuse of concrete for production of 'radioactive mortar'). The clearance of radioactive materials and their reuse require the strict respect of procedures and specifications. In our case, the Health Physics department under supervision of the Competent Authority establishes the procedures. This procedure is still a case by case practice but the legislation in Belgium is progressively put in place. For the recycling in the nuclear industry, we must respect the specifications of the end-user. Up to now, we have recycled low radioactive metals for the fabrication of shielding in the USA, so we had to respect the specifications of the melting facility and to obtain the authorisations for the transport abroad and for the transfer of property. Besides the radioactive waste route, we are using several evacuation routes for the dismantled materials: Evacuation of the cleared metals (iron, stainless steel, copper, electric motors...) to a local scrap dealer; Evacuation of metals to the Studsvik melting facility situated in Sweden: after clearance by the Swedish Authority, the non radioactive materials are sent to a local scrap dealer and the secondary radioactive waste is sent back to Belgium and conditioned by Belgoprocess. This technology further decontaminates the metals and allows performing an accurate

    Hazardous Materials Incidents (HMIs) have attracted a growing public concern worldwide. The health risks and environmental implications associated with HMIs are almost invariably severe, and underscore the urgency for sound management. Hazardous Materials Explosion incidents (HMEIs) belong to a category of extremely serious HMIs. Existing studies placed focuses predominately on the promptness and efficiency of emergency responses to HMIs and HMEIs. By contrast, post-disaster environmental management has been largely overlooked. Very few studies attempted to examine the post-disaster environmental management plan particularly its effectiveness and sufficiency. In the event of the Tianjin warehouse explosion (TWE), apart from the immediate emergency response, the post-disaster environmental management systems (P-EMSs) have been reported to be effective and sufficient in dealing with the environmental concerns. Therefore, this study aims to critically investigate the P-EMSs for the TWE, and consequently to propose a framework and procedures for P-EMSs in general for HMIs, particularly for HMEIs. These findings provide a useful reference to develop P-EMSs for HMIs in the future, not only in China but also other countries. Copyright © 2017. Published by Elsevier Ltd.

    GRB 160625B is an extremely bright outburst with well-monitored afterglow emission. The geometry-corrected energy is high, up to ∼5.2 × 10{sup 52} erg or even ∼8 × 10{sup 52} erg, rendering it the most energetic GRB prompt emission recorded so far. We analyzed the time-resolved spectra of the prompt emission and found that in some intervals there were likely thermal-radiation components and the high energy emission was characterized by significant cutoff. The bulk Lorentz factors of the outflow material are estimated accordingly. We found out that the Lorentz factors derived in the thermal-radiation model are consistent with the luminosity-Lorentz factor correlation found in other bursts, as well as in GRB 090902B for the time-resolved thermal-radiation components, while the spectral cutoff model yields much lower Lorentz factors that are in tension with the constraints set by the electron pair Compton scattering process. We then suggest that these spectral cutoffs are more likely related to the particle acceleration process and that one should be careful in estimating the Lorentz factors if the spectrum cuts at a rather low energy (e.g., ∼tens of MeV). The nature of the central engine has also been discussed, and a stellar-mass black hole is favored.

  2. Achieving transparency in carbon labelling for construction materialsLessons from current assessment standards and carbon labels

    Highlights: • The evolution of international GHG standards is reviewed. • The evolution of international carbon labelling schemes is reviewed. • The transparency requirements in carbon labelling schemes are revealed. • Key recommendations are provided to improve transparency in carbon labelling. - Abstract: The construction industry is one of the largest sources of carbon emissions. Manufacturing of raw materials, such as cement, steel and aluminium, is energy intensive and has considerable impact on carbon emissions level. Due to the rising recognition of global climate change, the industry is under pressure to reduce carbon emissions. Carbon labelling schemes are therefore developed as meaningful yardsticks to measure and compare carbon emissions. Carbon labelling schemes can help switch consumer-purchasing habits to low-carbon alternatives. However, such switch is dependent on a transparent scheme. The principle of transparency is highlighted in all international greenhouse gas (GHG) standards, including the newly published ISO 14067: Carbon footprint of products – requirements and guidelines for quantification and communication. However, there are few studies which systematically investigate the transparency requirements in carbon labelling schemes. A comparison of five established carbon labelling schemes, namely the Singapore Green Labelling Scheme, the CarbonFree (the U.S.), the CO 2 Measured Label and the Reducing CO 2 Label (UK), the CarbonCounted (Canada), and the Hong Kong Carbon Labelling Scheme is therefore conducted to identify and investigate the transparency requirements. The results suggest that the design of current carbon labels have transparency issues relating but not limited to the use of a single sign to represent the comprehensiveness of the carbon footprint. These transparency issues are partially caused by the flexibility given to select system boundary in the life cycle assessment (LCA) methodology to measure GHG emissions. The

    2007-01-01

    The specific objectives of the IAEA Coordinated Research Project (CRP) on Analyses of, and Lessons Learned from the Operational Experience with Fast Reactor Equipment and Systems are to - Preserve the feedback from commissioning, operation, and decommissioning experience of experimental and power sodium cooled fast reactors; - Enable easy access to the information from this feedback; - Produce lessons-learned/synthesis reports from the commissioning, operation, and decommissioning of experimental and power sodium cooled fast reactors. To achieve these objectives, the CRP participants will retrieve, assess and archive all the documentation and information relevant to feedback from commissioning, operation, and decommissioning of sodium cooled fast reactors. The archiving step may include conversion of the documents in electronic form and the preparation of electronic databases organized along scientific/technical topics and reactors. Then, the CRP will work on the critical review, assessment, and systematization of the available data, and will publish synthesis reports, including the appropriate recommendations from the 'lessons learned'. It is important to stress that these generalization efforts are crucial in view of the generational change occurring now: preserving the knowledge and experience of the generation who participated in the initial development work of sodium cooled fast reactors and is now retiring, and ultimately ensuring the systematic use of the operational feedback in the form of a 'lessons learned' approach, is essential since it was in the early stage of the studies that the key decisions and design choices were made. To accomplish the lessons-learned and synthesising work requires for as many as possible of the highly skilled specialists and pioneers in the sodium cooled fast reactor research and development area to be actively involved in the CRP. Thus, the first stage of the CRP will address feedback from operational experience with regard to

  13. The manufacture and use of sludge test materials for R and D purposes in the treatment and processing of magnox based sludge

    Blackburn, D.R.; Thompson, E.J.

    2013-01-01

    Among the Intermediate Level Waste materials in store and awaiting treatment and processing in the UK are quantities of magnesium hydroxide sludge. This sludge is a product of radioactive Magnox Swarf which arose from the de-canning of used magnox fuel element rods. As the Swarf was stored underwater, a corrosion reaction occurred over the course of time between the magnox and the water resulting in a magnesium hydroxide based sludge. The differing conditions and materials present in the various storage areas means that the sludge can range in consistency from that of a slurry through to a thick clay. Sludge test materials are required to underpin and validate the research and development equipment and processes that are to be used to treat the waste material. Necessary restrictions imposed on the sampling and testing of the radioactive waste means that the available data on the properties and behaviour of the sludge is limited. The raw materials used to create the sludge test materials are based upon magnesium hydroxide so that as far as possible the chemical behaviour will be similar to that of the waste material. The most representative sludge test material is manufactured by the corrosion of non-radioactive magnox or magnesium. However, time constraints make it impractical to supply this material in sufficient quantities for full scale validation trials. An alternative is to use sludge manufactured from commercially available magnesium hydroxide. The particle shape of commercially available materials differs from corrosion product magnesium hydroxide which means that properties such as the rheological behaviour cannot be replicated. Nevertheless, valuable trial data can be obtained, giving a greater degree of confidence in the waste treatment process than would be possible if only the more representative but less available corrosion product materials were to be used. Key test material parameters used in the trials have been identified as the particle size

    Purpose This article describes lessons from a Centers for Disease Control and Prevention initiative encompassing sodium reduction interventions in six communities. Design A multiple case study design was used. Setting This evaluation examined data from programs implemented in six communities located in New York (Broome County, Schenectady County, and New York City); California (Los Angeles County and Shasta County); and Kansas (Shawnee County). Subjects Participants (n = 80) included program staff, program directors, state-level staff, and partners. Measures Measures for this evaluation included challenges, facilitators, and lessons learned from implementing sodium reduction strategies. Analysis The project team conducted a document review of program materials and semi structured interviews 12 to 14 months after implementation. The team coded and analyzed data deductively and inductively. Results Five lessons for implementing community-based sodium reduction approaches emerged: (1) build relationships with partners to understand their concerns, (2) involve individuals knowledgeable about specific venues early, (3) incorporate sodium reduction efforts and messaging into broader nutrition efforts, (4) design the program to reduce sodium gradually to take into account consumer preferences and taste transitions, and (5) identify ways to address the cost of lower-sodium products. Conclusion The experiences of the six communities may assist practitioners in planning community-based sodium reduction interventions. Addressing sodium reduction using a community-based approach can foster meaningful change in dietary sodium consumption. PMID:24575726

    2015-03-01

    Full Text Available The public health nurses’ scope of practice explicitly includes child protection within their role, which places them in a prime position to identify child protection concerns. This role compliments that of other professions and voluntary agenices who work with children. Public health nurses are in a privileged position as they form a relationship with the child’s parent(s/guardian(s and are able to see the child in its own environment, which many professionals cannot. Child protection in Ireland, while influenced by other countries, has progressed through a distinct pathway that streamlined protocols and procedures. However, despite the above serious failures have occurred in the Irish system, and inquiries over the past 20 years persistently present similar contributing factors, namely, the lack of standardized and comprehensive service responses. Moreover, poor practice is compounded by the lack of recognition of the various interactional processes taking place within and between the different agencies of child protection, leading to psychological barriers in communication. This article will explore the lessons learned for public health nurses practice in safeguarding children in the Republic of Ireland.

  19. Materialism.

    2012-05-01

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

    New boilers in Europe shall be manufactured by the Manufacturer as contractor of the Customer based on PED (European Pressure Equipment Directive 97/23/EC), applicable as legal Directive since May 2002. According PED, the Manufacturer is equivalent to a legal person, responsible for calculation, design, fabrication at workshop and site, including final inspection and declaration of conformity, independent if work packages are subcontracted by Manufacturer or not. Based on Customer contract, Module G shall be used as process to prove conformity according PED. As principle, PED specifies fundamental safety requirements with main focus for materials, and fabrication. For 600 C / 620 C power plants with advanced steam conditions and considerably improving efficiency, new materials are necessary. For selection of the materials, attention has to be paid to the long term design strength values, the manufacturability of the materials as well as the corrosion and oxidation behaviour. Particularly the correct fabrication according to the state of the art closely linked to new discoveries about material behaviour for semi-finished products as well as for boiler components has to be ensured. These new materials are mainly not covered by PED respectively the harmonized standard EN 12952. For that reason and Customer contract with view on national legal directives which specifies the period of in-service inspection during the operational lifetime of the boiler, additional codes and standards shall be applied for boiler manufacturing. All these requirements shall be specified in the Quality Engineering Documents of Manufacturer. The presentation gives an overview of fundamentals of PED and describes the implementation of the requirements for materials, fabrication and inspections in the Quality Engineering Documents, both in the framework of PED and Customer contract. As part of Design Approval by NoBo according PED Module G, the Quality Engineering Documents are fundamental

The intent in producing such an inventory is to establish a record of past waste dumping and of accidents and losses at sea involving radioactive material, based on official reports, for use as an information base for the assessment of the impact of radionuclide sources in the marine environment, when deemed necessary. To respond to the request of the London Convention and Protocol, the IAEA has undertaken the development of the inventory to include radioactive waste resulting from dumping at sea, and accidents and losses which occurred at sea and involved radioactive material. The first IAEA report on this subject, Inventory of Radioactive Material Entering the Marine Environment: Sea Disposal of Radioactive Waste (IAEA-TECDOC-588), was published in 1991. The report was subsequently revised to include information provided by the Russian Federation regarding waste dumping operations conducted by the former Soviet Union in the Arctic and North-west Pacific Seas and some additional information provided by Sweden and the United Kingdom. The revised report, Inventory of Radioactive Waste Disposals at Sea (IAEA-TECDOC-1105), was published in 1999. A report on the information available at the IAEA on such incidents was published in 2001 as Inventory of Accidents and Losses at Sea Involving Radioactive Material (IAEA-TECDOC-1242). The present publication updates and combines IAEA-TECDOCs 1105 and 1242. It describes the contents of the inventory on waste dumping, accidents and losses at sea involving radioactive material. In order to prepare the publication, the IAEA, in cooperation with the International Maritime Organization (IMO), conducted a

    During the past four years, the Department of Energy -- Savannah River Operations Office and the Westinghouse Savannah River Company (WSRC) Environmental Restoration (ER) Program completed various activities ranging from waste site investigations to closure and post closure projects. Critiques for lessons learned regarding project activities are performed at the completion of each project milestone, and this critique interval allows for frequent recognition of lessons learned. In addition to project related lessons learned, ER also performs lessons learned critiques. T'he Savannah River Site (SRS) also obtains lessons learned information from general industry, commercial nuclear industry, naval nuclear programs, and other DOE sites within the complex. Procedures are approved to administer the lessons learned program, and a database is available to catalog applicable lessons learned regarding environmental remediation, restoration, and administrative activities. ER will continue to use this database as a source of information available to SRS personnel

  6. PENGEOM-A general-purpose geometry package for Monte Carlo simulation of radiation transport in material systems defined by quadric surfaces

    The Fortran subroutine package PENGEOM provides a complete set of tools to handle quadric geometries in Monte Carlo simulations of radiation transport. The material structure where radiation propagates is assumed to consist of homogeneous bodies limited by quadric surfaces. The PENGEOM subroutines (a subset of the PENELOPE code) track particles through the material structure, independently of the details of the physics models adopted to describe the interactions. Although these subroutines are designed for detailed simulations of photon and electron transport, where all individual interactions are simulated sequentially, they can also be used in mixed (class II) schemes for simulating the transport of high-energy charged particles, where the effect of soft interactions is described by the random-hinge method. The definition of the geometry and the details of the tracking algorithm are tailored to optimize simulation speed. The use of fuzzy quadric surfaces minimizes the impact of round-off errors. The provided software includes a Java graphical user interface for editing and debugging the geometry definition file and for visualizing the material structure. Images of the structure are generated by using the tracking subroutines and, hence, they describe the geometry actually passed to the simulation code.

    The programme goal was to show that the IAEA safe transport regulations adequately cover the thermal effects of an engine-room fire on plutonium transport packages stowed aboard a purpose-built ship. The packages are stored in transport containers located in a cargo hold of the ship. For this study, it was assumed that the packages in No 5 hold, adjacent to an engine-room, could be subject to heating due to a fire in the engine-room. The No 5 hold and the engine-room are separated by a water-filled bulkhead. This study addressed the heat transfer from an engine-room fire that could heat and evaporate water out of the water-filled bulkhead and the resulting temperature conditions around the packages and inside the packages near their elastometric seals.

  14. Micropropagation of transgenic lettuce containing HBsAg as a method of mass-scale production of standardised plant material for biofarming purposes.

    Micropropagation protocol of transgenic lettuce bearing S-, M- and L-HBsAg was developed for increased production of uniformised material for oral vaccine preparation. Effective manufacturing of plant-based biopharmaceuticals, including oral vaccines, depends on sufficient content of a protein of interest in the initial material and its efficient conversion into an administrable formulation. However, stable production of plants with a uniformised antigen content is equally important for reproducible processing. This can be provided by micropropagation techniques. Here, we present a protocol for micropropagation of transgenic lettuce lines bearing HBV surface antigens: S-, M- and L-HBsAg. These were multiplied through axillary buds to avoid the risk of somaclonal variation. Micropropagation effectiveness reached 3.5-5.7 per passage, which implies potential production of up to 6600 plant clones within a maximum 5 months. Multiplication and rooting rates were statistically homogenous for most transgenic and control plants. For most lines, more than 90 % of clones obtained via in vitro micropropagation had HBsAg content as high as reference plants directly developed from seeds. Clones were also several times more uniform in HBsAg expression. Variation coefficients of HBsAg content did not exceed 10 % for approximately 40-85 % of clones, or reached a maximum 20 % for 90 % of all clones. Tissue culture did not affect total and leaf biomass yields. Seed production for clones was decreased insignificantly and did not impact progeny condition. Micropropagation facilitates a substantial increase in the production of lettuce plants with high and considerably equalised HBsAg contents. This, together with the previously reported optimisation of plant tissue processing and its long-term stability, constitutes a successive step in manufacturing of a standardised anti-HBV oral vaccine of reliable efficacy.

  15. Lessons learned by southern states in designating alternative routes

    International Nuclear Information System (INIS)

    1989-08-01

    The purpose of this report is to discuss the ''lessons learned'' by the five states within the southem region that have designated alternative or preferred routes under the regulations of the Department of Transportation (DOT) established for the transportation of radioactive materials. The document was prepared by reviewing applicable federal laws and regulations, examining state reports and documents and contacting state officials and routing agencies involved in making routing decisions. In undertaking this project, the Southern States Energy Board hopes to reveal the process used by states that have designated alternative routes and thereby share their experiences (i.e., lessons learned) with other southern states that have yet to make designations. Under DOT regulations (49 CFR 177.826), carriers of highway route controlled quantities of radioactive materials (which include spent nuclear fuel and high-level waste) must use preferred routes selected to reduce time in transit. Such preferred routes consist of (1) an interstate system highway with use of an interstate system bypass or beltway around cities when available, and (2) alternate routes selected by a ''state routing agency.''

    The preliminary structural design guidelines for the experimental multi-purpose very-high temperature gas-cooled reactor have recently been prepared. The components of the primary system operating at temperatures of creep dominant range are grouped in those of pressure and temperature boundaries respectively. In the material selection, 2 1/4Cr-1Mo steel is chosen for the former and Hastelloy-X for the latter taking into account of material properties at operating temperature. Deriving from the literature in the field, material design data of the alloys are established in design forms such as Sy, So, Sm, St, 100% of minimum stress to rupture, design fatigue curves, isochronous stress-strain curves, creep-fatigue interaction damage factor and so on, which are defined in ASME Code Section III, Code Case 1592.

    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

    The purpose of this report is to document lessons learned in the installation of the hydrogen fueling station at the National Park Service Brentwood site in Washington, D.C., to help further the deployment of hydrogen infrastructure required to support hydrogen and other fuel cell technologies. Hydrogen fueling is the most difficult infrastructure component to build and permit. Hydrogen fueling can include augmenting hydrogen fueling capability to existing conventional fuel fueling stations as well as building brand new hydrogen fueling stations. This report was produced as part of the Brentwood Lessons Learned project. The project consisted of transplanting an existing modular hydrogen fueling station from Connecticut to the National Park Service Brentwood site. This relocation required design and construction at the Brentwood site to accommodate the existing station design as well as installation and validation of the updated station. One of the most important lessons learned was that simply moving an existing modular station to an operating site was not necessarily straight-forward - performing the relocation required significant effort and cost. The station has to function at the selected operating site and this functionality requires a power supply, building supports connecting to an existing alarm system, electrical grounding and lighting, providing nitrogen for purging, and providing deionized water if an electrolyzer is part of the station package. Most importantly, the station has to fit into the existing site both spatially and operationally and not disrupt existing operations at the site. All of this coordination and integration requires logistical planning and project management. The idea that a hydrogen fueling station can be simply dropped onto a site and made immediately operational is generally not realistic. Other important lessons learned include that delineating the boundaries of the multiple jurisdictions that have authority over a project for

    Full Text Available Background: Disasters have adverse impacts on different aspects of human life. Psychosocial Rehabilitation is one of the fields which is usually overshadowed and ignored by physical rehabilitation or its importance does not receive proper attention. This research attempts to study some lessons learned from Psychosocial Rehabilitation based on disaster experiences in Iran. Materials and Methods: This study has a conventional qualitative content analysis design. The participants of study were 15 people with direct experience of earthquake and 12 experts in this field. The study sample was selected by purposeful sampling method and the data were collected by semi-structured interviews. Results: Lack of a suitable system to deliver Psychosocial Rehabilitation, challenge in establishing balance between short-term and long-term social and mental needs, lack of mental and social experts, inefficiency in using social capital and capacities are the most important lessons learned in this field. Conclusion: Lack of awareness of mental and social problems of affected people after disaster is one of the most important barriers in successful and stable rehabilitation. Psychosocial Rehabilitation requires a suitable structure and planning for all stages of disaster management.

  15. Spent Nuclear Fuel Transportation: An Examination of Potential Lessons Learned From Prior Shipping Campaigns

    International Nuclear Information System (INIS)

    M. Keister; K, McBride

    2006-01-01

    The Nuclear Waste Policy Act of 1982 (NWPA), as amended, assigned the Department of Energy (DOE) responsibility for developing and managing a Federal system for the disposal of spent nuclear fuel (SNF) and high-level radioactive waste (HLW). The Office of Civilian Radioactive Waste Management (OCRWM) is responsible for accepting, transporting, and disposing of SNF and HLW at the Yucca Mountain repository (if licensed) in a manner that protects public health, safety, and the environment; enhances national and energy security; and merits public confidence. OCRWM faces a near-term challenge--to develop and demonstrate a transportation system that will sustain safe and efficient shipments of SNF and HLW to a repository. To better inform and improve its current planning, OCRWM has extensively reviewed plans and other documents related to past high-visibility shipping campaigns of SNF and other radioactive materials within the United States. This report summarizes the results of this review and, where appropriate, lessons learned. The objective of this lessons learned study was to identify successful, best-in-class trends and commonalities from past shipping campaigns, which OCRWM could consider when planning for the development and operation of a repository transportation system. Note: this paper is for analytical and discussion purposes only, and is not an endorsement of, or commitment by, OCRWM to follow any of the comments or trends. If OCRWM elects to make such commitments at a future time, they will be appropriately documented in formal programmatic policy statements, plans and procedures. Reviewers examined an extensive study completed in 2003 by DOE's National Transportation Program (NTP), Office of Environmental Management (EM), as well as plans and documents related to SNF shipments since issuance of the NTP report. OCRWM examined specific planning, business, institutional and operating practices that have been identified by DOE, its transportation contractors

    2015-01-01

    The purpose of this paper is to introduce the U.S. nuclear industrial's some key lessons learned especially for decommissioning planning based on which well informed decommissioning planning can be carried out. For a successful decommissioning, it is crucial to carry out a well-organized decommissioning planning before the decommissioning starts. This paper discussed four key factors which should be decided or considered carefully during the decommissioning planning period with introduction of related decommissioning lessons learned of U.S. nuclear industry. Those factors which have been discussed in this paper include the end state of a site, the overall decommissioning strategy, the management of the spent fuels, and the spent fuel pool island. Among them, the end state of a site should be decided first as it directs the whole decommissioning processes. Then, decisions on the overall decommissioning strategy (DECON vs. SAFSTOR) and the management of the spent fuels (wet vs. dry) should follow. Finally, the spent fuel pool island should be given due consideration because its implementation will result in much cost saving. Hopefully, the results of this paper would provide useful inputs to performing the decommissioning planing for the Kori unit 1

  6. Lesson Study-Building Communities of Learning Among Pre-Service Science Teachers

    Science.gov (United States)

    Hamzeh, Fouada

    Lesson Study is a widely used pedagogical approach that has been used for decades in its country of origin, Japan. It is a teacher-led form of professional development that involves the collaborative efforts of teachers in co-planning and observing the teaching of a lesson within a unit for evidence that the teaching practices used help the learning process (Lewis, 2002a). The purpose of this research was to investigate if Lesson Study enables pre-service teachers to improve their own teaching in the area of science inquiry-based approaches. Also explored are the self-efficacy beliefs of one group of science pre-service teachers related to their experiences in Lesson Study. The research investigated four questions: 1) Does Lesson Study influence teacher preparation for inquiry-based instruction? 2) Does Lesson Study improve teacher efficacy? 3) Does Lesson Study impact teachers' aspiration to collaborate with colleagues? 4) What are the attitudes and perceptions of pre-service teachers to the Lesson Study idea in Science? The 12 participants completed two pre- and post-study surveys: STEBI- B, Science Teaching Efficacy Belief Instrument (Enochs & Riggs, 1990) and ASTQ, Attitude towards Science Teaching. Data sources included student teaching lesson observations, lesson debriefing notes and focus group interviews. Results from the STEBI-B show that all participants measured an increase in efficacy throughout the study. This study added to the body of research on teaching learning communities, professional development programs and teacher empowerment.

  7. Refining MARGINS Mini-Lessons Using Classroom Observations

    Iverson, E. A.; Manduca, C. A.; McDaris, J. R.; Lee, S.

    2009-12-01

    One of the challenges that we face in developing teaching materials or activities from research findings is testing the materials to determine that they work as intended. Traditionally faculty develop material for their own class, notice what worked and didn’t, and improve them the next year. However, as we move to a community process of creating and sharing teaching materials, a community-based process for testing materials is appropriate. The MARGINS project has piloted such a process for testing teaching materials and activities developed as part of its mini-lesson project (http://serc.carleton.edu/margins/index.html). Building on prior work developing mechanisms for community review of teaching resources (e.g. Kastens, 2002; Hancock and Manduca, 2005; Mayhew and Hall, 2007), the MARGINS evaluation team developed a structured classroom observation protocol. The goals of field testing are to a) gather structured, consistent feedback for the lesson authors based on classroom use; b) guide reviewers of these lessons to reflect on research-based educational practice as a framework for their comments; c) collect information on the data and observations that the reviewer used to underpin their review; d) determine which mini-lessons are ready to be made widely available on the website. The protocol guides faculty observations on why they used the activity, the effectiveness of the activity in their classroom, the success of the activity in leading to the desired learning, and what other faculty need to successfully use the activity. Available online (http://serc.carleton.edu/margins/protocol.html), the protocol can be downloaded and completed during instruction with the activity. In order to encourage review of mini-lessons using the protocol, a workshop focused on review and revision of activities was held in May 2009. In preparation for the workshop, 13 of the 28 participants chose to field test a mini-lesson prior to the workshop and reported that they found this

  12. Phagocytosis: history's lessons.

    Science.gov (United States)

    Garg, Manish; Chandawarkar, Rajiv Y

    2013-01-01

    The assimilation of lessons from the past is an essential component of education for scientists of tomorrow. These lessons are not easy to find. History books on science are few and usually highly dramatized and biographies of scientists tend to exaggerate the pomp of scientific discovery. Both underplay the hard and laborious work that is integral to any scientific pursuit. Here we illustrate one such example. A century ago, the Nobel Prize in Medicine was awarded to two scientists: Ilya Metchnikoff, a Russian zoologist, for the discovery ofphagocytosis-a cell-mediated ingestion ofmicrobes; and Paul Ehrlich, a distinguished physician-scientist, for discovering a highly antigen-specific serum-derived antibody-based immune defense. These two diametrically opposing views of the host-pathogen interaction set the stage for a strife that led to seminal advancements in immunology. Mirrored in this journey are important lessons for scientists today--ubiquitously as applicable to modern scientific life as they were a century ago. This commentaryhighlights these lessons--a fitting centenary to a well-deserved recognition.

  16. Alternative Energy Lessons in Scotland

    Science.gov (United States)

    Boyle, Julie

    2010-05-01

    In Scotland the new science curriculum for pupils aged 12 to 15 shall include the following outcomes: "Using my knowledge and understanding, I can express an informed view on a national or global environmental issue;" "I have participated in constructing a model to harness a renewable source of energy and can investigate how to optimise the output;" and "I can discuss why it is important to me and to the future of the world that alternatives to fossil fuels are developed." There will be an emphasis on creating lessons that will nurture responsible citizens, improve pupil engagement and allow students to develop their team working skills. To help teachers plan lessons to address this, the Scottish Schools Equipment Research Centre and Edinburgh University made teaching materials on four renewable energy resources. This poster describes how their suggested activities on solar cells, wind turbines, hydroelectric power stations and wave power were used in science lessons with twelve year old students. After an initial class discussion based on issues related to climate change and diminishing fossil fuel supplies, a workshop activity was carried out in three stages. The students were issued with a fact sheet about one of four imaginary islands (Skisdale, Cloudy Island, Surfsville and Sun City) and they were asked to work in teams to choose the most suitable method of generating electricity for their island. Issues such as costs, where it will be sited and environmental implications were considered. They were then asked to conduct practical activities by constructing and testing models for these forms of renewable energy. To conclude, they presented their proposal to the rest of the class with reasoned explanations. The kits used in the lessons can be purchased from Anderson Scientific (sales@andersonscientific.co.uk). The solar cells were simply connected to a voltmeter. The wind and hydroelectric groups used the same basic equipment. This was made using a small water

  18. Epistemic Purposes to Prompt Argumentation in inquiry-based classes

    Directory of Open Access Journals (Sweden)

    Arthur Tadeu Ferraz

    2017-04-01

    Full Text Available Considering the growth in interest on argumentation in research on science education, in this paper our goal is to propose an overview of actions taken by a teacher that made possible to establish and mediate production of arguments by the students in classroom. For this purpose, we analyze a physics lesson where discussions were about light duality, through a planned inquiry-based sequence teaching. We developed a set of codes called Epistemic Purposes for Promotion of Argumentation that allow understanding teacher's purposes as well his actions to promote argumentation among students during inquiry-based lessons. According to theoretical proposition and empirical analysis, it was revealed that the construction of arguments by students has a high dependence on how ideas are problematized by teacher. The construction of understanding  by students requires teacher actions that result in contributions of different kinds.

    A lesson learned as defined in DOE-STD-7501-95, Development of DOE Lessons Learned Programs, is: A ``good work practice`` or innovative approach that is captured and shared to promote repeat applications or an adverse work practice or experience that is captured and shared to avoid a recurrence. The key word in both parts of this definition is ``shared``. This document was published to share a wide variety of recent Hanford experiences with other DOE sites. It also provides a valuable tool to be used in new employee and continuing training programs at Hanford facilities and at other DOE locations. This manual is divided into sections to facilitate extracting appropriate subject material when developing training modules. Many of the bulletins could be categorized into more than one section, however, so examination of other related sections is encouraged.

  4. An Assessment of Need for Instructional Professional Development for Middle School Science Teachers Using Interactive Lessons

    Science.gov (United States)

    Burton, Amanda

    Numerous studies on the impact of interactive lessons on student learning have been conducted, but there has been a lack of professional development (PD) programs at a middle school focusing on ways to incorporate interactive lessons into the science classroom setting. The purpose of this case study was to examine the instructional practices of science teachers to determine whether the need for an interactive lessons approach to teaching students exists. This qualitative case study focused on teachers' perceptions and pedagogy to determine whether the need to use interactive lessons to meet the needs of all students is present. The research question focused on identifying current practices and determining whether a need for interactive lessons is present. Qualitative data were gathered from science teachers at the school through interviews, lesson plans, and observations, all of which were subsequently coded using an interpretative analysis. The results indicated the need for a professional development (PD) program centered on interactive science lessons. Upon completion of the qualitative study, a detailed PD program has been proposed to increase the instructional practices of science teachers to incorporate interactive lessons within the science classroom. Implications for positive social change include improved teaching strategies and lessons that are more student-centered resulting in better understanding and comprehension, as well as performance on state-mandated tests.

  11. Exploring the role of curriculum materials to support teachers in science education reform

    Science.gov (United States)

    Schneider, Rebecca M.

    2001-07-01

    For curriculum materials to succeed in promoting large-scale science education reform, teacher learning must be supported. Materials were designed to reflect desired reforms and to be educative by including detailed lesson descriptions that addressed necessary content, pedagogy, and pedagogical content knowledge for teachers. The goal of this research was to describe how such materials contributed to classroom practices. As part of an urban systemic reform effort, four middle school teachers' initial enactment of an inquiry-based science unit on force and motion were videotaped. Enactments focused on five lesson sequences containing experiences with phenomena, investigation, technology use, or artifact development. Each sequence spanned three to five days across the 10-week unit. For each lesson sequence, intended and actual enactment were compared using ratings of (1) accuracy and completeness of science ideas presented, (2) amount student learning opportunities, similarity of learning opportunities with those intended, and quality of adaptations , and (3) amount of instructional supports offered, appropriateness of instructional supports and source of ideas for instructional supports. Ratings indicated two teachers' enactments were consistent with intentions and two teachers' enactments were not. The first two were in school contexts supportive of the reform. They purposefully used the materials to guide enactment, which tended to be consistent with standards-based reform. They provided students opportunities to use technology tools, design investigations, and discuss ideas. However, enactment ratings were less reflective of curriculum intent when challenges were greatest, such as when teachers attempted to present challenging science ideas, respond to students' ideas, structure investigations, guide small-group discussions, or make adaptations. Moreover, enactment ratings were less consistent in parts of lessons where materials did not include lesson specific

  12. Low level waste shipment accident lessons learned

    International Nuclear Information System (INIS)

    Rast, D.M.; Rowe, J.G.; Reichel, C.W.

    1995-01-01

    On October 1, 1994 a shipment of low-level waste from the Fernald Environmental Management Project, Fernald, Ohio, was involved in an accident near Rolla, Missouri. The accident did not result in the release of any radioactive material. The accident did generate important lessons learned primarily in the areas of driver and emergency response communications. The shipment was comprised of an International Standards Organization (ISO) container on a standard flatbed trailer. The accident caused the low-level waste package to separate from the trailer and come to rest on its top in the median. The impact of the container with the pavement and median inflicted relatively minor damage to the container. The damage was not substantial enough to cause failure of container integrity. The success of the package is attributable to the container design and the packaging procedures used at the Fernald Environmental Management Project for low-level waste shipments. Although the container survived the initial wreck, is was nearly breached when the first responders attempted to open the ISO container. Even though the container was clearly marked and the shipment documentation was technically correct, this information did not identify that the ISO container was the primary containment for the waste. The lessons learned from this accident have DOE complex wide applicability. This paper is intended to describe the accident, subsequent emergency response operations, and the lessons learned from this incident

    This is a script for a video about toxicology and the space shuttle. The first segment is deals with dust in the space vehicle. The next segment will be about archival samples. Then we'll look at real time on-board analyzers that give us a lot of capability in terms of monitoring for combustion products and the ability to monitor volatile organics on the station. Finally we will look at other issues that are about setting limits and dealing with ground based lessons that pertain to toxicology.

    In JENDL-3,2, the data on all the reactions having significant cross section over the neutron energy from 0.01 meV to 20 MeV are given for 340 nuclides. The object range of application extends widely, such as the neutron engineering, shield and others of fast reactors, thermal neutron reactors and nuclear fusion reactors. This is a general purpose data file. On the contrary to this, the file in which only the data required for a specific application field are collected is called special purpose file. The file for dosimetry is a typical special purpose file. The Nuclear Data Center, Japan Atomic Energy Research Institute, is making ten kinds of JENDL special purpose files. The files, of which the working groups of Sigma Committee are in charge, are listed. As to the format of the files, ENDF format is used similarly to JENDL-3,2. Dosimetry file, activation cross section file, (α, n) reaction data file, fusion file, actinoid file, high energy data file, photonuclear data file, PKA/KERMA file, gas production cross section file and decay data file are described on their contents, the course of development and their verification. Dosimetry file and gas production cross section file have been completed already. As for the others, the expected time of completion is shown. When these files are completed, they are opened to the public. (K.I.)

    2007-01-01

    Structural weld overlay (SWOL) has become a predominant mitigation technique within the Alloy 600 program. For the pressurizer nozzles, MRP-139 requires volumetric examination by year end 2007. Many nozzles are un-inspectable due to geometry and material limitations that preclude interrogation of the required examination volume. SWOL therefore is the mitigation technique which overcomes these limitations. SWOL of the pressurizer nozzles has been a challenge for all the vendors. Alloy 52 has proven to be difficult to weld under field conditions. The NDT technique chosen to demonstrate the integrity of the overlay needs to be adapted to the specific repair process and nozzle geometry. The purpose of this paper will be to present Westinghouse's integrated approach for SWOL with the focus on the NDT aspects. Topics will include main repair process steps, NDT qualification, recent field experience and lessons learned. (author)

    Rushdoony, H A

    1978-11-01

    Purpose of this paper is to present a model for teaching fourth grade children some aspects of the population geography of California from a nontextual approach. The objective is to interest and instruct children in the mobility of the people, and on the reasons why so many families have moved to California from other states. Students should be alerted not only to internal migration problems, but to the excess of births over deaths. Materials necessary for the lessons are transparencies, overhead projector, marking pencils, chalk and chalkboard. After showing the students that California population has approximately doubled every 20 years, the students should be encouraged to find reasons explaining why people have moved to the state, should be able to categorize those reasons under the terms industrial/manufacturing, agricultural, urban or recreational, should learn how to plot population distribution on a California regional outline map, and should attempt to explain why certain parts of California are more popular than others. The teaching model described in this paper may be replicated with modfications for any grade level and area of study.

  11. Space Stirling Cryocooler Contamination Lessons Learned and Recommended Control Procedures

    Science.gov (United States)

    Glaister, D. S.; Price, K.; Gully, W.; Castles, S.; Reilly, J.

    The most important characteristic of a space cryocooler is its reliability over a lifetime typically in excess of 7 years. While design improvements have reduced the probability of mechanical failure, the risk of internal contamination is still significant and has not been addressed in a consistent approach across the industry. A significant fraction of the endurance test and flight units have experienced some performance degradation related to internal contamination. The purpose of this paper is to describe and assess the contamination issues inside long life, space cryocoolers and to recommend procedures to minimize the probability of encountering contamination related failures and degradation. The paper covers the sources of contamination, the degradation and failure mechanisms, the theoretical and observed cryocooler sensitivity, and the recommended prevention procedures and their impact. We begin with a discussion of the contamination sources, both artificial and intrinsic. Next, the degradation and failure mechanisms are discussed in an attempt to arrive at a contaminant susceptibility, from which we can derive a contamination budget for the machine. This theoretical sensitivity is then compared with the observed sensitivity to illustrate the conservative nature of the assumed scenarios. A number of lessons learned on Raytheon, Ball, Air Force Research Laboratory, and NASA GSFC programs are shared to convey the practical aspects of the contamination problem. Then, the materials and processes required to meet the proposed budget are outlined. An attempt is made to present a survey of processes across industry.

    The purpose of this generic aging lessons learned (GALL) review is to provide a systematic review of plant aging information in order to assess materials and component aging issues related to continued operation and license renewal of operating reactors. Literature on mechanical, structural, and thermal-hydraulic components and systems reviewed consisted of 97 Nuclear Plant Aging Research (NPAR) reports, 23 NRC Generic Letters, 154 Information Notices, 29 Licensee Event Reports (LERs), 4 Bulletins, and 9 Nuclear Management and Resources Council Industry Reports (NUMARC IRs) and literature on electrical components and systems reviewed consisted of 66 NPAR reports, 8 NRC Generic Letters, 111 Information Notices, 53 LERs, 1 Bulletin, and 1 NUMARC IR. More than 550 documents were reviewed. The results of these reviews were systematized using a standardized GALL tabular format and standardized definitions of aging-related degradation mechanisms and effects. The tables are included in volumes 1 and 2 of this report. A computerized data base has also been developed for all review tables and can be used to expedite the search for desired information on structures, components, and relevant aging effects. A survey of the GALL tables reveals that all ongoing significant component aging issues are currently being addressed by the regulatory process. However, the aging of what are termed passive components has been highlighted for continued scrutiny. This report consists of Volume 2, which consists of the GALL literature review tables for the NUMARC Industry Reports reviewed for the report

  13. Optimization studies of carbon additives to negative active material for the purpose of extending the life of VRLA batteries in high-rate partial-state-of-charge operation

    2010-07-15

    The negative plates of lead-acid batteries subjected to partial-state-of-charge (PSOC) operation fail because of the development of an electrically inert film of lead sulfate on their surfaces. It has been found that carbon additives to the negative active material can significantly increase their cycle life in this type of operation. In this paper we show that various types of carbon, including graphite, carbon black eliminate the surface development of lead sulfate and that, in their presence, the lead sulfate becomes homogeneously distributed throughout the active material. Examination of active material by energy dispersive spectroscopy after extensive cycling shows that lead formed during charge of lead sulfate preferentially deposits on the carbon particles that have been embedded in the active material. Electrochemical studies have been carried out on a number of types of carbon additives having a wide range of properties. These included flake, expanded and synthetic graphite, isotropically graphitized carbon, carbon black and activated carbon. We have investigated their effect on the resistivity and surface areas of the negative active material and also on such electrochemical properties as active material utilization and cycle life. Most of the carbon additives increase the utilization of the active material and impressive increases in cycle life have been obtained with over 6000 capacity turnovers having been achieved. However, at this time, we have not been able to correlate either the type or the properties of the carbon with capacity or cycle life. Further work is needed in this area. The increases that have been achieved in cycle life provide evidence that the lead-acid battery is a viable low cost option for hybrid-electric vehicle use. (author)

    CERN Document Server

    Chadderton, Ronald A

    2015-01-01

    This textbook/course supplement stands as a unique and highly original complement to the traditional engineering economics curriculum. Its primarily narrative approach conveys the essence of an “Austrian" economic perspective on cash flow analysis and decision making in engineering, without extensive tables and graphs, and requires very little mathematics. The book’s objective is to add a new perspective to the usual study of cash flow analysis and solely econometric engineering decision making. The author draws on the methodology of the Austrian Economists—a school of economic thought that bases its study of economic phenomena on the interpretation and analysis of the purposeful actions of individuals. The book includes an array of illustrative case studies examined in detail by the author and emphasizes the importance of market processes and price signals to coordinate engineering plans. Purposeful Engineering Economics is an ideal resource for students, teaching faculty, and practicing professional ...

  16. Vitalism, purpose and superstition.

    Science.gov (United States)

    Lindeman, Marjaana; Saher, Marieke

    2007-02-01

    Developmental studies have shown that children assign purpose to objects more liberally than adults, and that they explain biological processes in terms of vitalistic causality. This study tested the hypothesis that similar misconceptions can be found among superstitious adults. The results from 116 superstitious and 123 sceptical individuals showed that more than sceptics, superstitious individuals attributed purpose to objects, and explained biological processes in terms of organ intentionality and energy transmission. In addition, they thought of energy as a vital force, attributing life and mental properties to it. These conceptual confusions were positively associated to all types of superstitions as well as belief in alternative medicine. The results support the argument that category mistakes and ontological confusions underlie superstitious and vitalistic thinking.

Through this lesson, teachers in secondary schools can provide the foundation of nationality through important events in the study of the social sciences. Many of the problems that occur in learning history, such as the boring and make sleepy. Everyone must have heard the term hypnosis, hypnotism, or hypnotherapy. Each person must also have a different view or understanding when hearing these terms. Hypnoteaching is one of the learning methods by using the art of communicating to influence learners. Hypnoteaching is a combination of five teaching-learning methods such as quantum learning, accelerate learning, power teaching, neuro-linguistic programming (NLP and hypnosis. Hypnoteaching can be done using informal hypnosis as well as formal hypnosis. Informal hypnosis is also called indirect hypnosis ie teachers can naturally make the Critical Area learners become no longer critical, through a very persuasive communication pattern. Here's what the teacher can do in Informal hypnosis: (1 get attention; (2 establishing Themes; (3 presenting the structure and regulations; (4 building relationships. If the learners are already comfortable and interested, the next step is to do a formal hypnosis before the lesson begins. Here are the steps that must be done: (1 Induction; (2 Deepening; (3 Deep level test; (4 Suggestion, and; (5 Termination.   Keywords: Historical learning, hypnoteaching, hypnosis, hypnotism, hypnotherapy, history Abstrak: Hipnoteaching dalam Pembelajaran Sejarah.

A new opportunity in M-learning is to use QR codes. This means that you don't have to print out worksheets with questions. You can hide question in the code and students can read them with their own devices on site. From the Master's thesis I also developed a tutorial material named "M-learning in a geography lesson" (in Estonian: M-õpe geograafiatunnis), you can see it in the webpage katrimope@wordpress.com. The tutorial received a second place on the Estonian study material contest in 2013. This is only one example on how to use M-learning. In Gustav Adolf Grammar School we use M-learning in lots of different subjects because it's really important in modern school to link new technologies, surrounding environment and learning for the purpose of better obtainment of knowledge.

    Collingridge, D.

    1984-01-01

    In an earlier article the author has argued that the turbulent history of nuclear power in Britain and the USA stems from the technology itself, and has little to do with the very different institutional arrangements made for the new technology in the two countries. Nuclear plant has various features which make its planning extraordinarily difficult. Its long lead time, large unit size, capital intensity and dependence on complex infrastructure combine to ensure that mistakes are likely to be made in planning the technology and that what mistakes do occur are expensive. This article aims to expand on the earlier one in two ways; by looking at the apparent success of the French nuclear programme which seems to run counter to the thesis of the earlier article, and by trying to draw lessons from the earlier analysis for the breeder reactor.

    Lesson "Balance in Nature" This simulation game-lesson (Balance in Nature) gives an opportunity for the students to show creativity, work independently, and to create models and ideas. It creates future-oriented thought connected to their experience, allowing them to propose solutions for global problems and personal responsibility for their activities. The class is divided in two teams. Each team chooses questions. 1. Question: Pollution in the environment. 2. Question: Care for nature and climate. The teams work on the chosen tasks. They make drafts, notes and formulate their solutions on small pieces of paper, explaining the impact on nature and society. They express their points of view using many different opinions. This generates alternative thoughts and results in creative solutions. With the new knowledge and positive behaviour defined, everybody realizes that they can do something positive towards nature and climate problems and the importance of individuals for solving global problems is evident. Our main goal is to recover the ecological balance, and everybody explains his or her own well-grounded opinions. In this work process the students obtain knowledge, skills and more responsible behaviour. This process, based on his or her own experience, dialogue and teamwork, helps the participant's self-development. Making the model "human↔ nature" expresses how human activities impact the natural Earth and how these impacts in turn affect society. Taking personal responsibility, we can reduce global warming and help the Earth. By helping nature we help ourselves. Teacher: Veselina Boycheva-Chapanova " Saint Patriarch Evtimii" Scholl Str.

  6. Lessons learned in radiology

    International Nuclear Information System (INIS)

    Goodenough, D.J.

    2001-01-01

    The paper reviews aspects of the history of radiology with the goal of identifying lessons learned, particularly in the area of radiological protection of the patient in diagnostic and interventional radiology, nuclear medicine and radiotherapy. It is pointed out that since the days of Roentgen there has been a need not only to control and quantify the amount of radiation reaching the patient but also to optimize the imaging process to offer the greatest diagnostic benefit within allowable levels of patient dose. To this end, in diagnostic radiology, one finds the development of better films, X rays tubes, grids, screens and processing techniques, while in fluoroscopy, one sees the increased luminance of calcium tungstate. In interventional radiology, one finds an improvement in catheterization techniques and contrast agents. In nuclear medicine, the development of tracer techniques into modern cameras and isotopes such as technetium can be followed. In radiotherapy, one sees the early superficial X rays and radium sources gradually replaced with radon seeds, supervoltage, 60 Co and today's linear accelerators. Along with the incredible advances in imaging and therapeutic technologies comes the growing realization of the potential danger of radiation and the need to protect the patient (as well as physicians, ancillary personnel and the general population) from unnecessary radiation. The important lesson learned is that we must walk a tightrope, balancing the benefits and risks of any technology utilizing radiation to produce the greatest benefits at the lowest acceptable risk. The alternative techniques using non-ionizing radiation will have to be considered as part of the general armamentarium for medical imaging whenever radiation consequences are unacceptable. (author)

  7. Lessons Learned from FUSRAP

    Castillo, Darina [U.S. Department of Energy, Office of Legacy Management; Carpenter, Cliff [U.S. Department of Energy, Office of Legacy Management; Miller, Michele [Navarro Research and Engineering

    2016-03-06

    The US DOE Office of Legacy Management (LM) is the long-term steward for 90 sites remediated under numerous regulatory regimes including the Formerly Utilized Sites Remedial Action Program (FUSRAP) sites. In addition, LM holds considerable historical information, gathered in the 1970s, to determine site eligibility for remediation under FUSRAP. To date, 29 FUSRAP sites are in LM’s inventory of sites for long-term surveillance and maintenance (LTS&M), and 25 are with the US Army Corps of Engineers (USACE) for remediation or in the process of being transitioned to LM. It is forecasted that 13 FUSRAP sites will transfer from the USACE to LM over the next 10 years; however, the timing of the transfers is strongly dependent upon federal funding of the ongoing remedial actions. Historically, FUSRAP sites were generally cleaned up for “unrestricted” industrial use or remediated to the “cleanup standards” at that time, and their use remained unchanged. Today, these sites as well as the adjacent properties are now changing or envisioned to have changes in land use, typically from industrial to commercial or residential uses. The implication of land-use change affects DOE’s LTS&M responsibility for the sites under LM stewardship as well as the planning for the additional sites scheduled to transition in time. Coinciding with land-use changes at or near FUSRAP sites is an increased community awareness of these sites. As property development increases near FUSRAP sites, the general public and interested stakeholders regularly inquire about the sufficiency of cleanups that impact their neighborhoods and communities. LM has used this experience to address a series of lessons learned to improve our program management in light of the changing conditions of our sites. We describe these lessons learned as (1) improved stakeholder relations, (2) enhanced LTS&M requirements for the sites, and (3) greater involvement in the transition process.

  10. Case Studies of Interactive Whole-Class Teaching in Primary Science: Communicative approach and pedagogic purposes

    Science.gov (United States)

    McMahon, Kendra

    2012-07-01

    By developing two case studies of expert teaching in action, this study aimed to develop knowledge of talk in whole-class teaching in UK primary science lessons and understand this in relation to both the teachers' interpretations and sociocultural theoretical frameworks. Lessons were observed and video-recorded and the teachers engaged in video-stimulated-reflective dialogue to capture participants' reflections upon their own pedagogic purposes and interactions in the classroom. The analytic framework was developed at three levels: sequence of lessons, lesson, and episode. For each episode, the 'communicative approach' and teaching purposes were recorded. Transcripts were developed for fine grain analysis of selected episodes and a quantitative analysis was undertaken of the use of communicative approaches. Findings exemplify how different communicative approaches were used by the case-study teachers for different pedagogical purposes at different points in the sequence of lessons, contributing to primary teachers' repertoire for planning and practice. The initial elicitation of children's ideas can be understood as pooling them to enhance multivoicedness and develop a shared resource for future dialogues. Whole-class talk can support univocality by rehearsing procedural knowledge and exploring the meanings of scientific terminology. Identifying salient features of phenomena in the context of the whole-class marks them as significant as shared knowledge but valuing other observations extends the multivoicedness of the discourse.

  14. Lessons learned from accidents in radiotherapy

    International Nuclear Information System (INIS)

    Ortiz-Lopez, P.; Haywood, J.

    1996-01-01

    Radiotherapy is the only application of radiation which intentionally delivers very high doses to humans. A gross deviation from the prescribed dose or dose distribution can have severe, or even fatal consequences. Since the patient is placed directly in the beam or sources are inserted in the body, any mistake made with the beam or the sources leads almost certainly to an accidental exposure. Lessons learned from previous incidents can be used to test the vulnerability of a given facility, provided that these are adequately disseminated. The purpose of this paper is to present a summary of the lessons learned from a relatively large sample of events. The analysis has been presented as a short description followed by an identification of the triggering event and the contributing factors. These have been grouped as follows: errors in commissioning or calibration machines and sources affecting many patients; mistakes affecting individual patients such as irradiating the wrong patient, the wrong, field or site, and mistakes when entering data into or reading from the patient's chart; error due to unusual treatments or situations; equipment failure and human machine problems, including maintenance.

  15. Arms control: moral, political and historical lesson

    International Nuclear Information System (INIS)

    Thompson, K.W.

    1990-01-01

    Many of the world's most influential policy-makers and analysts view arms control as a scientific and technological problem. They measure a nation's nuclear power exclusively by megatonnage and throw-weights leaving the intangible elements of military and political power to philosophers and historians. They tend to ignore the human and qualitative aspects of power. This is a book that shift the emphasis to aspects of the nuclear problem which are sometimes overlooked. Basically, these elements are bound up in the moral, political, and historical lessons of the nuclear age. Nonquantitative factors have been central to studies of national defense and military power since the rise of the modern nation state system. However, most students of present-day nuclear weapons tend to stress their revolutionary character. Because they are considered wholly unique, analysts tend to write about them in a historical and apolitical terms. One purpose of the collection of papers in this little volume is to redirect attention to the moral, political, and historical lessons that the nuclear age presents. What most distinguishes the writings of contributors to this volume is their use of certain well-established principles and concepts long acknowledged in military and foreign policy analysis. Thus Father Hehir asks many of the same questions that students of ethics and foreign policy have asked for four hundred years

  16. Governing nanobiotechnology: lessons from agricultural biotechnology regulation

    International Nuclear Information System (INIS)

    Johnson, Robbin S.

    2011-01-01

    This article uses lessons from biotechnology to help inform the design of oversight for nanobiotechnology. Those lessons suggest the following: first, oversight needs to be broadly defined, encompassing not just regulatory findings around safety and efficacy, but also public understanding and acceptance of the technology and its products. Second, the intensity of scrutiny and review should reflect not just risks but also perceptions of risk. Finally, a global marketplace argues for uniform standards or commercially practical solutions to differences in standards. One way of designing oversight to achieve these purposes is to think about it in three phases—precaution, prudence, and promotion. Precaution comes early in the technology or product’s development and reflects real and perceived uncertainties. Prudence governs when risks and hazards have been identified, containment approaches established, and benefits broadly defined. Transparency and public participation rise to the fore. The promotional phase moves toward shaping public understanding and acceptance and involves marketing issues rather than safety ones. This flexible, three-phase approach to oversight would have avoided some of the early regulatory problems with agricultural biotechnology. It also would have led to a more risk-adjusted pathway to regulatory approval. Furthermore, it would avoid some of the arbitrary, disruptive marketing issues that have arisen.

    Radiotherapy is the only application of radiation which intentionally delivers very high doses to humans. A gross deviation from the prescribed dose or dose distribution can have severe, or even fatal consequences. Since the patient is placed directly in the beam or sources are inserted in the body, any mistake made with the beam or the sources leads almost certainly to an accidental exposure. Lessons learned from previous incidents can be used to test the vulnerability of a given facility, provided that these are adequately disseminated. The purpose of this paper is to present a summary of the lessons learned from a relatively large sample of events. The analysis has been presented as a short description followed by an identification of the triggering event and the contributing factors. These have been grouped as follows: errors in commissioning or calibration machines and sources affecting many patients; mistakes affecting individual patients such as irradiating the wrong patient, the wrong, field or site, and mistakes when entering data into or reading from the patient`s chart; error due to unusual treatments or situations; equipment failure and human machine problems, including maintenance.

  18. Sustaining Lesson Study: Resources and Factors that Support and Constrain Mathematics Teachers' Ability to Continue After the Grant Ends

    Science.gov (United States)

    Druken, Bridget Kinsella

    Lesson study, a teacher-led vehicle for inquiring into teacher practice through creating, enacting, and reflecting on collaboratively designed research lessons, has been shown to improve mathematics teacher practice in the United States, such as improving knowledge about mathematics, changing teacher practice, and developing communities of teachers. Though it has been described as a sustainable form of professional development, little research exists on what might support teachers in continuing to engage in lesson study after a grant ends. This qualitative and multi-case study investigates the sustainability of lesson study as mathematics teachers engage in a district scale-up lesson study professional experience after participating in a three-year California Mathematics Science Partnership (CaMSP) grant to improve algebraic instruction. To do so, I first provide a description of material (e.g. curricular materials and time), human (attending district trainings and interacting with mathematics coaches), and social (qualities like trust, shared values, common goals, and expectations developed through relationships with others) resources present in the context of two school districts as reported by participants. I then describe practices of lesson study reported to have continued. I also report on teachers' conceptions of what it means to engage in lesson study. I conclude by describing how these results suggest factors that supported and constrained teachers' in continuing lesson study. To accomplish this work, I used qualitative methods of grounded theory informed by a modified sustainability framework on interview, survey, and case study data about teachers, principals, and Teachers on Special Assignment (TOSAs). Four cases were selected to show the varying levels of lesson study practices that continued past the conclusion of the grant. Analyses reveal varying levels of integration, linkage, and synergy among both formally and informally arranged groups of

    Full Text Available The repressive reaction involves, as any human action, a certain finality. As the punishment's essence is the suffering, then, in the course of time it has been arisen the question regarding the goal for which the society utilizes the suffering and for what the society punishes. According to the classic penal doctrine that bases on the idea of retribution, the repressive reaction was limited to a simple revenge and it didn't existed any concern in order to influence the doer's future behaviour. In the positivist conception, the punishment's purpose was to shelter the society against the offender's new attacks. Going up to an extreme point with this idea, the positivists equated the punishment with the curative treatment at which the patients in the hospitals were submitted and which it was adequate to each category of offender. For the positivists, the penal sanction, it was meant to combat the organic or the psychological anomalies or the dysfunctions of the social environment that have influenced the offender and that determined him to commit antisocial deeds. In the modern vision, the punishment cannot have a goal on its own and that is to answer to bad with bad because it doesn't come from an abstract desire for revenge, but from a concrete necessity of hindering the repetition of the antisocial deeds and of defending the fundamental social values.

  1. Drilling for scientific purpose

    1987-09-01

    Drilling for scientific purpose is a process of conducting geophysical exploration at deep underground and drilling for collecting crust samples directly. This is because earth science has advanced to get a good understanding about the top of the crust and has shifted its main interest to the lower layer of the crust in land regions. The on-land drilling plan in Japan has just started, and the planned drilling spots are areas around the Minami River, Hidaka Mts., kinds of the Mesozoic and Cenozoic granite in outside zone, the extension of Japan Sea, Ogasawara Is., Minami-Tori Is., and active volcanos. The paper also outlines the present situation of on-land drilling in the world, focusing on the SG-3rd super-deep well SG-3 on the Kola Peninsula, USSR, Satori SG-1st well SG-1 in Azerbaidzhan S.S.R, V.S.S.R, Sweden's wells, Cyprus' wells, Bayearn well Plan in West Germany, and Salton Sea Scientific Drilling Program in the U.S. At its end, the paper explains the present situation and the future theme of the Japanese drilling technique and points out the necessity of developing equipment, and techniques.

  2. Mathematics teachers’ reflective practice within the context of adapted lesson study

    2012-11-01

    Full Text Available There seems to be paucity of research in South Africa on mathematics teachers’ reflective practice. In order to study this phenomenon, the context of lesson study (in an adapted form was introduced to five mathematics teachers in a rural school in the Free State. The purpose was to investigate their reflective practice whilst they collaboratively planned mathematics lessons and reflected on the teaching of the lessons. Data were obtained through interviews, video-recorded lesson observations, field notes taken during the lesson study group meetings and document analyses (lesson plans and reflective writings. The adapted lesson study context provided a safe space for teachers to reflect on their teaching and they reported an increase in self-knowledge and finding new ways of teaching mathematics to learners. This finding has some potential value for planning professional learning programmes in which teachers are encouraged to talk about their classroom experiences, share their joys and challenges with one another and strive to build a community of reflective practitioners to enhance their learners’ understanding of mathematics.

  5. Multi-purpose reactor

    International Nuclear Information System (INIS)

    1991-05-01

    The Multi-Purpose-Reactor (MPR), is a pool-type reactor with an open water surface and variable core arrangement. Its main feature is plant safety and reliability. Its power is 22MW t h, cooled by light water and moderated by beryllium. It has platetype fuel elements (MTR type, approx. 20%. enriched uranium) clad in aluminium. Its cobalt (Co 60 ) production capacity is 50000 Ci/yr, 200 Ci/gr. The distribution of the reactor core and associated control and safety systems is essentially based on the following design criteria: - upwards cooling flow, to waive the need for cooling flow inversion in case the reactor is cooled by natural convection if confronted with a loss of pumping power, and in order to establish a superior heat transfer potential (a higher coolant saturation temperature); - easy access to the reactor core from top of pool level with the reactor operating at full power, in order to facilitate actual implementation of experiments. Consequently, mechanisms associated to control and safety rods s,re located underneath the reactor tank; - free access of reactor personnel to top of pool level with the reactor operating at full power. This aids in the training of personnel and the actual carrying out of experiments, hence: - a vast water column was placed over the core to act as radiation shielding; - the core's external area is cooled by a downwards flow which leads to a decay tank beyond the pool (for N 16 to decay); - a small downwards flow was directed to stream downwards from above the reactor core in order to drag along any possibly active element; and - a stagnant hot layer system was placed at top of pool level so as to minimize the upwards coolant flow rising towards pool level

    The recent history of Oryx provides invaluable lessons for those who plan future energy strategies, relates the author of this paper. When Oryx became an independent oil and gas company, its reserves were declining, its stock was selling below asset values, and the price of oil seemed stuck below $15 per barrel. The message from Oryx management to Oryx employees was: We are in charge of our own destiny. We are about to create our own future. Oryx had developed a new, positive corporate culture and the corporate credit required for growth. This paper points to two basic principles that have guided the metamorphosis in Oryx's performance. The first objective was to improve operational efficiency and to identify the right performance indicators to measure this improvement. It states that the most critical performance indicator for an exploration and production company must be replacement and expansion of reserves at a competitive replacement cost. Oryx has cut its finding costs from $12 to $5 per barrel, while the BP acquisition provided proven reserves at a cost of only $4 per barrel. Another performance indicator measures Oryx's standing in the financial markets

  9. Patient safety: lessons learned

    International Nuclear Information System (INIS)

    Bagian, James P.

    2006-01-01

    The traditional approach to patient safety in health care has ranged from reticence to outward denial of serious flaws. This undermines the otherwise remarkable advances in technology and information that have characterized the specialty of medical practice. In addition, lessons learned in industries outside health care, such as in aviation, provide opportunities for improvements that successfully reduce mishaps and errors while maintaining a standard of excellence. This is precisely the call in medicine prompted by the 1999 Institute of Medicine report ''To Err Is Human: Building a Safer Health System.'' However, to effect these changes, key components of a successful safety system must include: (1) communication, (2) a shift from a posture of reliance on human infallibility (hence ''shame and blame'') to checklists that recognize the contribution of the system and account for human limitations, and (3) a cultivation of non-punitive open and/or de-identified/anonymous reporting of safety concerns, including close calls, in addition to adverse events.

    2011-01-01

    These lessons learned are part of a suite of hardware, software, test results, designs, knowledge base, and documentation that comprises the legacy of the Constellation Program. The context, summary information, and lessons learned are presented in a factual format, as known and described at the time. While our opinions might be discernable in the context, we have avoided all but factually sustainable statements. Statements should not be viewed as being either positive or negative; their value lies in what we did and what we learned that is worthy of passing on. The lessons include both "dos" and "don ts." In many cases, one person s "do" can be viewed as another person s "don t"; therefore, we have attempted to capture both perspectives when applicable and useful. While Volume I summarizes the views of those who managed the program, this Volume II encompasses the views at the working level, describing how the program challenges manifested in day-to-day activities. Here we see themes that were perhaps hinted at, but not completely addressed, in Volume I: unintended consequences of policies that worked well at higher levels but lacked proper implementation at the working level; long-term effects of the "generation gap" in human space flight development, the need to demonstrate early successes at the expense of thorough planning, and the consequences of problems and challenges not yet addressed because other problems and challenges were more immediate or manifest. Not all lessons learned have the benefit of being operationally vetted, since the program was cancelled shortly after Preliminary Design Review. We avoid making statements about operational consequences (with the exception of testing and test flights that did occur), but we do attempt to provide insight into how operational thinking influenced design and testing. The lessons have been formatted with a description, along with supporting information, a succinct statement of the lesson learned, and

    Full Text Available One of the purposes of physical education (PE in both Norway and Denmark is that PE should inspire to a lifelong active lifestyle. Based on the self-determination theory, the aim of the present study was to compare students’ intrinsic motivation, extrinsic motivation, and perceived competence in a lifestyle sport inspired PE-lesson (disc golf to a traditional PE-lesson (soccer and general PE. In addition, we aimed to investigate whether differences in motivation and perceived competence were conditional of the students’ relative attitude toward PE. The result of the study revealed that perceived competence was higher in the disc golf-lesson compared to the soccer-lesson and general PE. No overall differences in intrinsic motivation were found. However, when investigating differences in intrinsic motivation according to the students’ relative attitude toward PE, the results indicated that the students with a negative attitude toward PE was significantly more intrinsically motivated in disc golf-lesson compared to soccer-lesson and general PE. The findings may be seen as further recommendations to physical educators to vary the activity choices in physical education classes.

    Research finds that student teachers often fail to make observable instructional goals, without which a secure bridge between instruction and assessment is precluded. This is one reason that recent reports state that teacher education needs to become better at helping student teachers to develop their thinking about and skills in assessing pupils' learning. Currently in Europe, the Lesson Study method and the Content Representation tool, which both have a specific focus on assessment, have started to address this problem. This article describes and discusses an intervention in which Lesson Study was used in combination with Content Representation in student teachers' field practice. Empirical materials from one group of student teachers were analyzed to illustrate how the student teachers worked with assessment during the planning of a lesson, how they implemented it in a research lesson, and how they used the gathered observations to make claims about assessment aims. The findings suggest that the student teachers placed greater emphasis on assessment through the intervention. However, it is also found that more attention should have been dedicated to the planning phase and that the group did not manage to keep a research focus throughout the Lesson Study process. This suggests that it properly would be beneficial with several planning sessions prior to the research lesson, as well as having an expert teacher leading the Lesson Study.

  16. Preservation and Implementation of Decommissioning Lessons Learned in the United States Nuclear Regulatory Commission

    International Nuclear Information System (INIS)

    Rodriguez, Rafael L.

    2008-01-01

    Over the past several years, the United States Nuclear Regulatory Commission (NRC) has actively worked to capture and preserve lessons learned from the decommissioning of nuclear facilities. More recently, NRC has involved industry groups, the Organization of Agreement States (OAS), and the Department of Energy (DOE) in the effort to develop approaches to capture, preserve and disseminate decommissioning lessons learned. This paper discusses the accomplishments of the working group, some lessons learned by the NRC in the recent past, and how NRC will incorporate these lessons learned into its regulatory framework. This should help ensure that the design and operation of current and future nuclear facilities will result in less environmental impact and more efficient decommissioning. In summary, the NRC will continue capturing today's experience in decommissioning so that future facilities can take advantage of lessons learned from today's decommissioning projects. NRC, both individually and collectively with industry groups, OAS, and DOE, is aggressively working on the preservation and implementation of decommissioning lessons learned. The joint effort has helped to ensure the lessons from the whole spectrum of decommissioning facilities (i.e., reactor, fuel cycle, and material facilities) are better understood, thus maximizing the amount of knowledge and best practices obtained from decommissioning activities. Anticipated regulatory activities at the NRC will make sure that the knowledge gained from today's decommissioning projects is preserved and implemented to benefit the nuclear facilities that will decommission in the future

    Materials behaviors caused by neutron irradiation under fission and/or fusion environments can be little understood without practical examination. Easily accessible material information system with large material database using effective computers is necessary for design of nuclear materials and analyses or simulations of the phenomena. The developed Embrittlement Data Base (EDB) at ORNL is this comprehensive collection of data. EDB database contains power reactor pressure vessel surveillance data, the material test reactor data, foreign reactor data (through bilateral agreements authorized by NRC), and the fracture toughness data. The lessons learned from building EDB program and the associated database management activity regarding Material Database Design Methodology, Architecture and the Embedded QA Protocol are described in this report. The development of IAEA International Database on Reactor Pressure Vessel Materials (IDRPVM) and the comparison of EDB database and IAEA IDRPVM database are provided in the report. The recommended database QA protocol and database infrastructure are also stated in the report.

    Severe accidents occurred at Fukushima Daiichi Nuclear Power Station stirred up people's great expectation of nuclear robot's deployment. However unexpected nuclear disaster, especially rupture of reactor building caused by core meltdown and hydrogen explosion, made it quite difficult to introduce nuclear robot under high radiation environment to cease accidents and dispose damaged reactor. Robotics Society of Japan (RSJ) set up committee to look back upon lessons learned from 50 year's past experience of nuclear robot development and summarized 'Lessons of nuclear robot history', which was shown on the home page website of RSJ. This article outlined it with personal comment. History of nuclear robot developed for inspection and maintenance at normal operation and for specific required response at nuclear accidents was reviewed with many examples at home and abroad for TMI, Chernobyl and JCO accidents. Present state of Fukushima accident response robot's introduction and development was also described with some comments on nuclear robot development from academia based on lessons. (T. Tanaka)

    During the Tarragona International Seminar the participating high-level specialists had very open and fruitful discussion concerning strategic decommissioning issues. The lessons learnt and possible solutions for future work issues can be found below. Although there appears to be a trend towards early dismantling, there seemed to be general agreement that technical solutions support a wide variety of safe decommissioning approaches. Thus, in terms of decommissioning strategy, it appears that no one size fits all. A flexible regulatory approach is needed in order to recognize the changing operational risks and physical conditions of facilities with time, and to optimise their dismantling. The NEA has released a comprehensive study on decommissioning strategies and costs that indicates world-wide progress. According to this report, over 50% of countries with nuclear facilities have a framework of decommissioning requirements and 60% have defined radioactive waste clearance levels. Up to about 70% of the costs of D and D are attributable to dismantling and waste management. The provisions for safety of the D and D process are closely linked to the availability of the necessary funds as and when required. A number of common factors were defined for successful implementation of decommissioning strategies: i.e. safety, technical feasibility of decommissioning options, risk-informed progression of D and D activities as project proceeds, maintenance of competency and corporate memory throughout project, waste management and disposal capability, financing that suits the scope of the project, a well-defined risk-informed and performance-based regulatory process, and establishment of effective communication with local and regional governments and key stakeholders, particularly personnel, at the earliest opportunity before decommissioning.

  5. Putting Gino's lesson to work: Actor-network theory, enacted humanity, and rehabilitation.

    Science.gov (United States)

    Abrams, Thomas; Gibson, Barbara E

    2016-02-01

    This article argues that rehabilitation enacts a particular understanding of "the human" throughout therapeutic assessment and treatment. Following Michel Callon and Vololona Rabeharisoa's "Gino's Lesson on Humanity," we suggest that this is not simply a top-down process, but is cultivated in the application and response to biomedical frameworks of human ability, competence, and responsibility. The emergence of the human is at once a materially contingent, moral, and interpersonal process. We begin the article by outlining the basics of the actor-network theory that underpins "Gino's Lesson on Humanity." Next, we elucidate its central thesis regarding how disabled personhood emerges through actor-network interactions. Section "Learning Gino's lesson" draws on two autobiographical examples, examining the emergence of humanity through rehabilitation, particularly assessment measures and the responses to them. We conclude by thinking about how rehabilitation and actor-network theory might take this lesson on humanity seriously. © The Author(s) 2016.

  6. Using authentic materials for students of tourism in Slovenia: English language acquisition for students of the Faculty of Tourism of the University of Maribor

    Directory of Open Access Journals (Sweden)

    Potočnik Topler Jasna

    2014-12-01

    Full Text Available The article examines the process of teaching English for specific purposes at the Faculty of Tourism of the University of Maribor, Slovenia using coursebooks and authentic supplementary materials. The survey has shown that the students of the Faculty of Tourism prefer supplementary authentic materials to coursebooks because they find them sufficiently interesting or challenging. Specially designed classroom materials that are put into the Moodle by the teacher also offer opportunities for various activities in lesson planning for teaching, listening, speaking, reading and writing. Another important aspect of supplementary materials is that they facilitate the teacher’s creativity. However, there are advantages and disadvantages to using only coursebooks or only specially prepared classroom materials, and both - coursebooks and supplementary materials - should be used only after careful consideration. Although authentic materials may contain complex grammatical structures and difficult vocabulary, they bring real-life situations into classrooms, and students therefore find them very motivating, the survey has shown.

The DOE has shared the Type A packaging information throughout the nuclear materials transportation community. During testing, there have been recurring areas of packaging design that resulted in testing delays and/or initial failure. The lessons learned during the testing are considered a valuable resource. DOE requested that WHC share this resource. By sharing what is and can be encountered during packaging testing, individuals will hopefully avoid past mistakes

  8. Lessons learned related to packaging and transportation

    The use of lessons learned as a tool for learning from past experiences is well established, especially by many organizations within the nuclear industry. Every person has, at some time, used the principles of lessons learned to adopt good work practices based on their own experiences or the experiences of others. Lessons learned can also help to avoid the recurrence of adverse practices, which is often an area that most lessons-learned programs tend to focus on. This paper will discuss how lessons learned relate to packaging and transportation issues and events experienced at Department of Energy (DOE) facilities. It will also discuss the role performed by the Office of Nuclear and Facility Safety's Office of Operating Experience Analysis and Feedback in disseminating lessons learned and operating experience feedback to the DOE complex. The central concept of lessons learned is that any organization should be able to learn from its own experiences and events. In addition, organizations should implement methodologies to scan external environments for lessons learned, to analyze and determine the relevance of lessons learned, and to bring about the necessary changes learned from these experiences. With increased concerns toward facility safety, the importance of utilizing the lessons-learned principles and the establishment of lessons-learned programs can not be overstated

    Full Text Available The classroom with its teaching-learning dynamics creates a kind of “embryonic society” in which the micro-policies of collective social knowledge construction and meaning can be re-constructed; therefore, it can be considered as a kind of “mirror” of political culture. Thus, comparative lesson research, which requires indepth classroom observation, has been getting much attention among educational community. On the other hand, there have not been done many studies that represent social studies and civics in particular, in this research tradition. Naturally, this research tradition is based on qualitative research paradigm. Likewise, qualitative research tradition has been getting increasing attention among educational community. Thus, the first purpose of this article is to explain all documentation and pre-interpretation process of this lesson so that it can provide an example for qualitative researchers. The second purpose of this article is to provide an example lesson of political education from Turkey so that educators worldwide can compare one example of social studies education practice in Turkey and with their countries.

    As manned space exploration takes on the task of traveling beyond low Earth orbit, many problems arise that must be solved in order to make the journey possible. One major task is protecting humans from the harsh space environment. The current method of protecting astronauts during Extravehicular Activity (EVA) is through use of the specially designed Extravehicular Mobility Unit (EMU). As more rigorous EVA conditions need to be endured at new destinations, the suit will need to be tailored and improved in order to accommodate the astronaut. The Objective behind the EMU Lessons Learned Database(LLD) is to be able to create a tool which will assist in the development of next-generation EMUs, along with maintenance and improvement of the current EMU, by compiling data from Failure Investigation and Analysis Reports (FIARs) which have information on past suit failures. FIARs use a system of codes that give more information on the aspects of the failure, but if one is unfamiliar with the EMU they will be unable to decipher the information. A goal of the EMU LLD is to not only compile the information, but to present it in a user-friendly, organized, searchable database accessible to all familiarity levels with the EMU; both newcomers and veterans alike. The EMU LLD originally started as an Excel database, which allowed easy navigation and analysis of the data through pivot charts. Creating an entry requires access to the Problem Reporting And Corrective Action database (PRACA), which contains the original FIAR data for all hardware. FIAR data are then transferred to, defined, and formatted in the LLD. Work is being done to create a web-based version of the LLD in order to increase accessibility to all of Johnson Space Center (JSC), which includes converting entries from Excel to the HTML format. FIARs related to the EMU have been completed in the Excel version, and now focus has shifted to expanding FIAR data in the LLD to include EVA tools and support hardware such as

    Failure analysis can be a very useful tool to designers and operators of plant and equipment. It is not simply something that is done for lawyers and insurance companies, but is a tool from which lessons can be learned and by means of which the 'breed' can be improved. In this presentation, several failure investigations that have contributed to understanding will be presented. Specifically, the following cases will be discussed: 1) A fire at a refinery that occurred in a desulphurization unit. 2) The failure of a pipeline before it was even put into operation. 3) Failures in locomotive axles that took place during winter operation. The refinery fire was initially blamed on defective Type 321 seamless stainless steel tubing, but there were conflicting views between 'experts' involved as to the mechanism of failure and the writer was called upon to make an in-depth study. This showed that there were a variety of failure mechanism involved, including high temperature fracture, environmentally-induced cracking and possible manufacturing defects. The unraveling of the failure sequence is described and illustrated. The failure of an oil transmission was discovered when the line was pressure tested some months after it had been installed and before it was put into service. Repairs were made and failure occurred in another place upon the next pressure test being conducted. After several more repairs had been made the line was abandoned and a lawsuit was commenced on the basis that the steel was defective. An investigation disclosed that the material was sensitive to embrittlement and the causes of this were determined. As a result, changes were made in the microstructural control of the product to avoid similar problems in future. A series of axle failures occurred in diesel electric locomotives during winter. An investigation was made to determine the nature of the failures which were not by classical fatigue, nor did they correspond to published illustrations of Cu

    Full Text Available The article considers the complex geopolitical situation in the global world at the end of the second decade of the 21st century as determined by the consequences of the collapse of the Soviet Union and by the new world order. The author seeks to answer the questions who will define the current geopolitical situation, whose aims it will reflect, what will become the basis of new geopolitical realities, the basis of moral solidarity of humankind, and the spiritual basis of future civilizations. The new challenges give rise to a desperate struggle for different scenarios for building a happy life. Moreover, it is not clear which ideal of the future world will be widely supported as a development guideline. The recognition as such of the standard of living and development of the strongest ones becomes a real threat to the new civilization for it leads to the loss of national interests of sovereign states, and to the loss of an independent future. Today, there is an active search for new theories and concepts that will adequately explain con-temporary global processes. In this thematic context, the author identifies main lessons not learned by the world political elites. The first lesson: new states are not born in an empty place, their common history is a great advantage ensuring prospects for the further development of interstate cooperation. The second lesson: the widespread falsification of history has a negative impact on national, cultural and social-group identity in transforming societies. The third lesson: after the collapse of the Soviet Union, the post-war balance of power was destroyed together with the system of checks and balances in world politics (a bipolar model of the world. The fourth lesson: under radical social transformations, the moral system of the population devaluates with numerous crisis consequences.

    International Nuclear Information System (INIS)

    Kupp, R.W.

    1983-01-01

    Separated and decontaminated plutonium - out of a reactor, in a bottle, tank or canister represents an easy target for diversion into possible non-peaceful uses. It also presents a situation that is of concern from a terrorist attack standpoint. Because this special nuclear material has such national and international sensitivity, storage for those quantities which are ''in excess'' of those necessary to be used for peaceful purposes is of concern to the Nations of the World. Recognizing these concerns, Article XII.A.5 of the IAEA Statutes was developed (1956) and the introduction to this Sub-article 5 states ''...that with respect to any Agency Project or other arrangements where the Agency is requested by the parties concerned to apply safeguards, the Agency shall have the following rights and responsibilities to the extent relevant to the project or arrangement....'' Article XII.A.5 then continues: ''To approve the means to be used for chemical processing.... to insure that this chemical processing will not lend itself to diversion of materials for military purposes.... to require that special additional materials recovered or produced as by-product be used for peaceful purposes under continuing Agency safeguards, for research or in reactors.... and to require deposit with the Agency of any excess.... over what is needed for the above stated uses in order to prevent stockpiling of these materials, provided that thereafter, at the request of the member or members concerned.... (plutonium) shall be returned promptly.... for use under the same provisions as stated above.''

    1998-07-01

    In 1993, a workshop was convened at the National Renewable Energy Laboratory (NREL) to discuss the issues of applying renewable energy in a sustainable manner to international rural development. One of the summary recommendations was that NREL could assist in the renewable energy for rural electrification effort by developing and supplying six related activities: resource assessment, comparative analysis and modeling, performance monitoring and analysis, pilot project development, internet-based project data, communications, and training. In response to this recommendation, NREL launched its Village Power Program consisting of these activities that cut across NREL technologies and disciplines. Currently NREL is active in 20 countries, with pilot projects in 12 of those countries. At this time the technologies include photovoltaics, wind, biomass, and hybrids. The rural applications include home lighting and communications, water pumping, schools and health posts, battery charging stations, ecotourism, and village systems. These pilot projects are central to the renewable energy village power development through the demonstration of three aspects critical to replication and implementation of the projects on a significant scale. The three aspects are technical functionality, economic competitiveness, and institutional sustainability. It is important to note that the pilot projects from which NREL's experience has been gained were funded and, in many cases, developed by other organizations and agencies. NREL's role has been one of technical assistance or project management or both. The purpose of this paper is to describe the lessons NREL staff has gleaned from their participation in the various pilot projects. The author hopes that these lessons will help the Renewable Energy-Based Rural Electrification (RERE) community in implementing sustainable projects that lead to replication.

  17. Teaching Norwegian to Beginners: Six Principles to Guide Lesson Planning

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Teaching a foreign language is no simple task. There are several factors to consider, from curriculum design, to material selection and lesson implementation, to assessment. The challenge, however, is even greater, if you are teaching a less commonly taught language such as Norwegian – a language spoken by fewer than six million native speakers, used almost exclusively in one country, and with a limited number of available pedagogical materials. Under such circumstances, the task of preparing high quality communicative lessons is immense, even for an experienced language instructor. The goal of this article is to present how a successful language lesson can be developed even if one is using a textbook that does not foster communicative competence. As an example, I am using a unit from a Norwegian textbook for beginners: På vei, often used in Norwegian as a second language course for adults in Norway. The lesson focuses on routines and times of the day, and it concludes with the students comparing and contrasting their daily routines with a partner. Prior to this lesson, students have learned to provide basic information about themselves (where they come from, what languages they speak, what they do for work, expressions for greetings and goodbyes, basic verbs relating to daily activities such as ‘snakker’ (to speak, ‘kjører’ (to drive, ‘kjøpper’ (to buy, ‘jobber’ (to work, ‘leser’ (to read, ‘scriver’ (to write, ordinal numerals, meals, some food items, some basic prepositions and locations, words for family members, and subject and object pronouns for all persons. If you were to closely follow the textbook in teaching this unit, you would begin by teaching the students how to tell time, then briefly go over some verbs to express daily routines, listen to and read a text titled ‘Jeg står opp klokka seks,’ a narrative about Monica’s day (Monica is one of the characters in the book, and finally ask the students

    This thesis presents a distributed architecture for the use of wireless sensors in the management of electrical distribution systems. Although the general concept of using wireless sensors for measuring quantities of power lines has previously been introduced, the proposed solutions have not been well integrated within the power system equipment and the automation system. This has severely compromised the applicability of the sensors in the field. However, wireless sensors have several features that make them an attractive instrumentation solution in the harsh environment of electrical distribution networks. Wireless sensors do not need signal or power cables and they are therefore easy to install and use in system refurbishment. They thus provide an interesting and cost effective alternative that is worth studying. In this thesis, the concept developed for enhancing the applicability and integration of wireless sensors within the power distribution system is based on an architecture that uses the properties of the system itself to preserve functionality and to minimise the power consumption and thus the size and weight of the wireless sensors. In this architecture the following essential components and aspects are identified. First, a time synchronisation method for wireless sensors is developed. The main goal with this method is to provide energy optimised means to determine the phase angle in wireless sensor cells where several sensors measure phase current and one sensor measures voltage. Secondly, a fault detection and location method with wireless sensors is proposed. This method enables implementation of fault management using wireless sensors that operate autonomously and asynchronously and measure only phase current. With this approach the hardware and software implementation of a sensor can be simplified compared to previous solutions. The combination of these developed methods enables the construction of lighter, smaller and more flexible wireless sensors. Consequently, the ability to integrate the sensors within components and equipment as well as their robustness and functionality are enhanced. Third, an architecture for the distributed management of electrical distribution networks is developed. The primary intention with this architecture is to provide a distributed computing platform that integrates the wireless sensors within the automation system and manages the related functionality in a controlled and simple way. The developed architecture also creates a generic concept for distributed and local control in the management of electrical distribution systems. This concept will be valuable in the future when the vast amount of data produced by sensors must be locally processed to avoid saturating the communication and computational resources of the control centre.

    -going. Despite the need to adapt protocols and approaches to each specific context, there is a need for a common research agenda and sharing of what works and does not. Concerted efforts have been made to improve information-sharing and to draw on lessons learned to advance technical and organisational challenges. However many health workers have limited access to quality information due to barriers such as internet access and language. For example, one recent initiative identified less than 10% of resources are available in French, despite high caseloads of acute malnutrition in francophone West Africa. Key actions to address challenges in information-sharing include: -Improve availability of and access to translated information -Increase use of social media, e-learning and audio-visual materials for extended reach and use of information -Stimulate interactive dialogue and sharing between practitioners for improved problem solving and learning -Strengthen the collaboration between complementary initiatives. In one decade significant advances in the adaptation and implementation of community-based management of acute malnutrition approach have been made in various contexts, but challenges to quality service delivery, scale-up and sustainability remain. It is time to draw on what we know to support scale-up and have equitable access to treatment to the millions of children who still remain outside of existing services. (author)

  1. Safety of the Transport of Radioactive Materials for Civilian Use in France. Lessons learned by IRSN from analysis of significant events reported in 2014 and 2015. Mission report 2016

    International Nuclear Information System (INIS)

    2017-01-01

    IRSN publishes its report on the safety of transport of radioactive materials for civilian use in France for the years 2014 and 2015. It is based on an overall review of the significant events that occurred during this period during transport operations in France by road, railway, inland waterway, sea and air of 980 000 parcels loaded with radioactive substances. In 2014 and 2015, respectively 139 and 122 events were reported, which is about one event reported for 7,500 packages carried. While these figures are up significantly compared to 2013 (93 reported events, or 1 in 10,000 packages carried), IRSN believes that this trend should not however be interpreted as a deterioration of the safety level of the transport of radioactive materials. Indeed, it is largely explained by better detection of events relevant to safety by the actors concerned and therefore their declaration to the authorities. None of these events had significant radiological consequences for the workers, the population or the environment. As part of progress made, IRSN notes a sharp decrease, in 2015, in the number of damage of packages intended for medical activities during their handling in airport areas. This decrease is linked to awareness actions conducted for airlines companies and staff involved in the handling of packages. Finally, three themes must be the subject of particular vigilance of the actors concerned and of corrective actions: - Compliance with the requirements for the transport of gamma radiography devices, in particular those associated with the locking of the source; events related to the transport of gamma radiography devices appeared as remarkable events over the period (3 level 1 events and 1 level 2 events); - The tie-down of packages on their means of transport, given the risks of fall of the package during transport, as well as tie-down of the objects in their transport container; - The operations of filling and closing of drums containing uranium ore in order to

  2. The Employed Neurosurgeon: Essential Lessons.

    Science.gov (United States)

    Benzil, Deborah L; Zusman, Edie E

    2017-04-01

    Neurosurgeons are highly specialized surgeons whose pride is mastery of the complexity of form and function that is the nervous system and then knowing when and how these require surgical intervention. Following years of arduous postgraduate education, neurosurgeons enter the world of practice that is not only daunting in its intricacies of regulations, mandates, and unknown business practices, but also changing at a meteoric pace. Overwhelmingly, graduating residents and fellows are choosing to practice as employed physicians, a trend that is new in its magnitude and also changed because of the rapid evolution of large health systems. Case studies of challenges other employed surgical specialists have faced can provide critical and important education for any neurosurgeon in this arena. As with the lessons of all case studies, the teachings are remarkably universal, but how those lessons apply to an individual's specific situation will require personalized adaptation.

    Full Text Available Including in a novel information about relief, climate, vegetation, fauna and various aspects of socio-economic life can make literature a real source of geographical information. Using realistic literary works in Geography lessons has multiple benefits, which are not limited only to geographical knowledge. In this paper there are some fragments from literature, suggestions of activities about how to integrate the fragments during Geography lessons and the results of these activities. The activities are from fifth to twelfth grade, passing through a first example of water pollution resulting from a Hercules labour, through the lyricism of the aurora borealis description, through the dramatic life of a refugee from Darfur, through the Dobrudgea winter landscape, through the grey urban landscape of Bucharest in the 90s and so on. Students were put into learning situations that stimulated their creativity, developed communication competencies and enriched their general knowledge.

    Abstract. On March 11, 2011, an earthquake and subsequent tsunamis off the Pacific coastline of Japan's Tohoku region caused widespread devastation in Japan. As of June 10, 2016, it is reported that a total of 15,894 people lost their lives and 2,558 people are still unaccounted for. In Fukushima Prefecture, approximately 100,000 people are still obliged to live away from their homes due to the earthquake and tsunami as well as the Fukushima Daiichi accident. On the day, the earthquake and tsunami caused severe damages to the Tokyo Electric Power Company (TEPCO)'s Fukushima Daiichi Nuclear Power Station (NPS). All the units in operation, namely Units 1 to 3, were automatically shut down on seismic reactor protection system trips but the earthquake led to the loss of all off-site electrical power supplies to that site. The subsequent tsunami inundated the site up to 4 to 5 m above its ground level and caused, in the end, the loss of core cooling function in Units 1 to 3, resulting in severe core damages and containment vessel failures in these three units. Hydrogen was released from the containment vessels, leading to explosions in the reactor buildings of Units 1, 3 and 4. Radioactive materials were released to the atmosphere and were deposited on the land and in the ocean. One of the most important lessons learned is an importance to prevent such large scale common cause failures due to extreme natural events. This leads to a conclusion that application of the defense-in-depth philosophy be enhanced because the defense-in-depth philosophy has been and continues to be an effective way to account for uncertainties associated with risks. From the human and organizational viewpoints, the final report from the Investigation Committee of the Government pointed out so-called "safety myth" that existed among nuclear operators including TEPCO as well as the government, that serious severe accidents could never occur in nuclear power plants in Japan. After the accident, the

    Lessons from the four-year ARIES (Advanced Reactor Innovation and Evaluation Study) investigation of a number of commercial magnetic-fusion-energy (MFE) power-plant embodiments of the tokamak are summarized. These lessons apply to physics, engineering and technology, and environmental, safety, and health (ES ampersand H) characteristics of projected tokamak power plants. Summarized herein are the composite conclusions and lessons developed in the course of four conceptual tokamak power-plant designs. A general conclusion from this extensive investigation of the commercial potential of tokamak power plants is the need for combined, symbiotic advances in both physics, engineering, and materials before economic competitiveness with developing advanced energy sources can be realized. Advances in materials are also needed for the exploitation of environmental advantages otherwise inherent in fusion power

  6. Scheduling lessons learned from the Autonomous Power System

    Ringer, Mark J.

    1992-01-01

    The Autonomous Power System (APS) project at NASA LeRC is designed to demonstrate the applications of integrated intelligent diagnosis, control, and scheduling techniques to space power distribution systems. The project consists of three elements: the Autonomous Power Expert System (APEX) for Fault Diagnosis, Isolation, and Recovery (FDIR); the Autonomous Intelligent Power Scheduler (AIPS) to efficiently assign activities start times and resources; and power hardware (Brassboard) to emulate a space-based power system. The AIPS scheduler was tested within the APS system. This scheduler is able to efficiently assign available power to the requesting activities and share this information with other software agents within the APS system in order to implement the generated schedule. The AIPS scheduler is also able to cooperatively recover from fault situations by rescheduling the affected loads on the Brassboard in conjunction with the APEX FDIR system. AIPS served as a learning tool and an initial scheduling testbed for the integration of FDIR and automated scheduling systems. Many lessons were learned from the AIPS scheduler and are now being integrated into a new scheduler called SCRAP (Scheduler for Continuous Resource Allocation and Planning). This paper will service three purposes: an overview of the AIPS implementation, lessons learned from the AIPS scheduler, and a brief section on how these lessons are being applied to the new SCRAP scheduler.

  7. Keynote on lessons from major radiation accidents

    International Nuclear Information System (INIS)

    Ortiz, P.; Oresegun, M.; Wheatley, J.

    2000-01-01

    Generic lessons have been learned from a relatively large number of accidents in the most relevant practices (a set of analysis have been made on about 90 radiotherapy events, 43 industrial radiography and nine from industrial irradiations); more specific lessons have been drawn from in-depth investigations of individual accidents. The body of knowledge is grouped as follows: a) radiotherapy is very unique in that humans (patients) are purposely given very high radiation doses (20-75 Gy) by placing them in the radiation beam or by placing radioactive sources in contact with tissues. Intended deterministic effects are the essence of the normal radiotherapy practice and relatively small deviation from the intended doses, i.e,, slightly higher or lower than intended may cause increased rate of severe complication or reduce probability of cure. Consequences of major accidents have been devastating, affecting tens, even hundreds of patients and causing death (directly or indirectly) to a large number of them; b) accidents involving industrial radiography are the most frequent cause of overexposure to workers (radiographers); c) accidents with industrial irradiators have lower probability of occurrence, however, they are deemed to be fatal, especially when whole body exposure to panoramic gamma irradiators occur; partial body irradiation from industrial or research accelerator beams has led to amputation of hands and legs; d) when control of sources was relinquished ('orphan' sources) this has resulted in severe injuries, in some cases death and widespread contamination of the environment. A tool for further dissemination of lessons will be an international reporting system of unusual radiation events (RADEV), being introduced world-wide. Accidents were rarely due to a single human error or isolated equipment failure. In most cases there was a combination of elements such as: a) unawareness of the potential for an accident, b) poor education, which usually did not

    The major premise of this project is that teachers learn from the act of teaching a lesson. Rather than asking "What must a teacher already know in order to practice effectively?", this project asks "What might a teacher learn through their activities in the classroom and how might this learning be optimised?" In this project, controlled conditions are created utilising purposefully designed and trialled lesson plans to investigate the process of teacher knowledge construction, with teacher selective attention proposed as a key mediating variable. In order to investigate teacher learning through classroom practice, the project addresses the following questions: To what classroom objects, actions and events do teachers attend and with what consequence for their learning? Do teachers in different countries attend to different classroom events and consequently derive different learning benefits from teaching a lesson? This international project combines focused case studies with an online survey of mathematics teachers' selective attention and consequent learning in Australia, China and Germany. Data include the teacher's adaptation of a pre-designed lesson, the teacher's actions during the lesson, the teacher's reflective thoughts about the lesson and, most importantly, the consequences for the planning and delivery of a second lesson. The combination of fine-grained, culturally situated case studies and large-scale online survey provides mutually informing benefits from each research approach. The research design, so constituted, offers the means to a new and scalable vision of teacher learning and its promotion.

    Florence Nightingale made a profound statement about leadership when she returned from the Crimean War without the fanfare offered to her. Promoters paraded her empty carriage around the city of Southampton England to applaud her accomplishments in the war. Her absence signaled a new leadership, one of quiet determination, humility, and political strategy to improve quality of life. The lessons to be learned for today's nurse leaders revolve around mindfulness, clarity of purpose, reverence for human life, collaborative partnerships, co-evolution, engagement, keeping up with a world in motion, and making meaning.

    Full Text Available This paper gives an overview on the deepest EU’s recession since the 1930s. The purpose of this study is to analyze the main macroeconomic indicators and their domino effect, in times of crisis. The abrupt downturn of the EU economy wasn’t entirely an unpredicted event. This is why the impact of the macroeconomic instability should never be underestimated in the future. Prevention, control and resolution represent elementary lessons from the way the current economic crisis has been handled. The analysis, added to the disruptions caused by the economic crisis, shows that the recession continues to weigh on the perspectives and solutions of the macroeconomic stability.

    Nowicki, Barbara L.; Sullivan-Watts, Barbara; Shim, Minsuk K.; Young, Betty; Pockalny, Robert

    2013-06-01

    Elementary teachers face increasing demands to engage children in authentic science process and argument while simultaneously preparing them with knowledge of science facts, vocabulary, and concepts. This reform is particularly challenging due to concerns that elementary teachers lack adequate science background to teach science accurately. This study examined 81 in-classroom inquiry science lessons for preservice education majors and their cooperating teachers to determine the accuracy of the science content delivered in elementary classrooms. Our results showed that 74 % of experienced teachers and 50 % of student teachers presented science lessons with greater than 90 % accuracy. Eleven of the 81 lessons (9 preservice, 2 cooperating teachers) failed to deliver accurate science content to the class. Science content accuracy was highly correlated with the use of kit-based resources supported with professional development, a preference for teaching science, and grade level. There was no correlation between the accuracy of science content and some common measures of teacher content knowledge (i.e., number of college science courses, science grades, or scores on a general science content test). Our study concluded that when provided with high quality curricular materials and targeted professional development, elementary teachers learn needed science content and present it accurately to their students.

    This article describes lessons from a Centers for Disease Control and Prevention initiative encompassing sodium reduction interventions in six communities. A multiple case study design was used. This evaluation examined data from programs implemented in six communities located in New York (Broome County, Schenectady County, and New York City); California (Los Angeles County and Shasta County); and Kansas (Shawnee County). Participants (n = 80) included program staff, program directors, state-level staff, and partners. Measures for this evaluation included challenges, facilitators, and lessons learned from implementing sodium reduction strategies. The project team conducted a document review of program materials and semistructured interviews 12 to 14 months after implementation. The team coded and analyzed data deductively and inductively. Five lessons for implementing community-based sodium reduction approaches emerged: (1) build relationships with partners to understand their concerns, (2) involve individuals knowledgeable about specific venues early, (3) incorporate sodium reduction efforts and messaging into broader nutrition efforts, (4) design the program to reduce sodium gradually to take into account consumer preferences and taste transitions, and (5) identify ways to address the cost of lower-sodium products. The experiences of the six communities may assist practitioners in planning community-based sodium reduction interventions. Addressing sodium reduction using a community-based approach can foster meaningful change in dietary sodium consumption.

    Full Text Available Nowadays, project-based organizations need to utilize intellectual capital and knowledge to become leader in their business activities. The new approach to use knowledge based skills from one side and development of the new complicated products from the other side have increased the need for designing a lessons learned model. The purpose of this paper is to design a lessons learned model to improve the success of new product development for project oriented organizations. The study designs a questionnaire in Likert scale and distributes it among 56 experts who were well informed about various techniques of new product development and lessons learned. Cronbach alphas for all components of the survey were well above the desirable level. The results of the survey have indicated that there were positive and meaningful relationships between lessons learned components and the success of the new product development.

  11. Lessons learned -- a comparison of the proposed on-site waste management facilities at the various Department of Energy sites

    International Nuclear Information System (INIS)

    Ciocco, J.; Singh, D.; Survochak, S.; Elo, M.

    1996-01-01

    The Department of Energy Sites (DOE) are faced with the challenge of managing several categories of waste generated from past or future cleanup activities, such as 11(e)2 byproduct material, low-level radioactive (LL), low-level radioactive mixed (LLM), transuranic (TRU), high level radioactive (HL), and hazardous waste (HW). DOE must ensure safe and efficient management of these wastes while complying with all applicable federal and state laws. Proposed waste management strategies for the EM-40 Environmental Restoration (ER) program at these sites indicate that on-site disposal is becoming a viable option. For purposes of this paper, on-site disposal cells managed by the EM-40 program at Hanford, Weldon Spring, Fernald Environmental Management Project (FEMP) and Rocky Flats were compared. Programmatic aspects and design features were evaluated to determine what comparisons can be made, and to identify benefits lessons learned that may be applicable to other sites. Based on comparative analysis, it can be concluded that the DOE EM-40 disposal cells are very unique. Stakeholders played a major role in the decision to locate the various DOE on-site disposal facilities. The disposal cells will be used to manage 11(e)2 by-product materials, LL, LLM, and/or HLW. The analysis further suggests that the design criteria are comparable. Lessons learned relative to the public involvement activities at Weldon Spring, and the design approach at Hanford should be considered when planning future on-site disposal facilities at DOE sites. Further, a detailed analysis of progress made at Hanford should be evaluated for application at sites such as Rocky Flats that are currently planning on-site disposal facilities

    Bartholomew, John B; Jowers, Esbelle M

    2011-06-01

    Although schools are an ideal location to conduct interventions that target children, the emphasis on standardized testing makes it difficult to implement interventions that do not directly support academic instruction. In response, physically active academic lessons have been developed as a strategy to increase physical activity while also addressing core educational goals. Texas I-CAN! is one incarnation of this approach. We will review the on-going research on the impact of these active lessons on: teacher implementation, child step count, child attention control, and academic performance. The collected studies support the impact of physically active academic lessons on each area of interest. If these data can be replicated, it suggests that teachers might find these lessons of benefit to their primary role as educators, which should ease dissemination of these and other physically active lessons in elementary schools.

    The Chernobyl accident led to a drastic increase the incidents of thyroid cancer in children living at territories contaminated with radionuclides. The incidents of hemoblastoses which are etiologically closely related to radiation did not change after the incident. The lessons of the decade that passed since the accident necessitate measures aimed at alleviation of the medical consequences of the accident which are to be implemented for many years. The program of such measures should be based on a strictly scientific evaluation of each factor, that will be conductive to a most adequate state financing of this work [ru

    Southwest Airlines continues to garner accolades in the areas of customer service, workforce management, and profitability. Since both the health care and airlines industries deal with a service rather than a product, the customer experience depends on the people who deliver that experience. Employees' commitment or "loyalty" to their customers, their employer, and their work translates into millions of dollars of revenue. What employee wants to work for "the worst employer in town?" Nine loyalty lessons from Southwest can be carried over to the health care setting for the benefit of employees and patients.

    2011-04-01

    The purpose of this report is to identify possible issues highlighted by these lessons learned that could apply to the NGNP in reducing technical risks commensurate with the current phase of design. Some of the lessons learned have been applied to the NGNP and documented in the Preconceptual Design Report. These are addressed in the background section of this document and include, for example, the decision to use TRISO fuel rather than BISO fuel used in the Peach Bottom reactor; the use of a reactor pressure vessel rather than prestressed concrete found in Fort St. Vrain; and the use of helium as a primary coolant rather than CO2. Other lessons learned, 68 in total, are documented in Sections 2 through 6 and will be applied, as appropriate, in advancing phases of design. The lessons learned are derived from both negative and positive outcomes from prior HTGR experiences. Lessons learned are grouped according to the plant, areas, systems, subsystems, and components defined in the NGNP Preconceptual Design Report, and subsequent NGNP project documents.

  1. Lessons learned and advice from Vietnam war nurses: a qualitative study.

    Science.gov (United States)

    Scannell-Desch, Elizabeth A

    2005-03-01

    The aim of this paper is to describe guidance for nurses today from the lessons learned by nurses who served in the Vietnam War. There is little research focusing on nurses' experiences in the Vietnam War. Lessons learned and subsequent advice from nurses who served in Vietnam may be helpful to those serving in current and future wars. A Husserlian phenomenological approach was taken, using interviews with a purposive sample of Registered Nurses who were female, and had served in the United States of America armed forces in Vietnam during the war. Seven theme clusters described the lesson learned and guidance offered by the Vietnam War nurses: advice about journaling, training, caring for yourself, use of support systems, talking about your experiences, understanding the mission, and lack of preparation for war. Much can be learned from the lessons learned and advice given by Vietnam War nurses. These lessons stress that nurses need to take a pro-active role in preparing themselves for deployment to a war zone, and that institutional training for war needs to be intensive and realistic. The environmental, cultural, technological, clinical and psychosocial demands of war nursing need to be comprehensively addressed before nurses deploy to a war.

    Full Text Available Primary object lessons, by Norman Allison Calkins, ranslated by Rui Barbosa, a book that was widely disseminated in Brazil during the final years of the 19th century and the beginning of the 20th century, presents object teaching as a general method to be used in every subject or primary school. This article analyses Calkins’ book according to its presentation of mathematical content, focusing particularly on geometry lessons. It also iscusses five features of the approach adopted by Calkins: the presentation of plane geometry before geometry in space, the several materials necessary to the teaching of geometry, the drawing lessons associated with the lessons on shape, the sequence of presentation of the contents and the relations between geometry teaching and children’s pleasure and curiosity. Comments about the utilization and circulation of Calkins’ manual in geometry teaching in Brazil are also provided.

  4. Can lessons designed with Gestalt laws of visual perception improve students' understanding of the phases of the moon?

    Science.gov (United States)

    Wistisen, Michele

    There has been limited success teaching elementary students about the phases of the moon using diagrams, personal observations, and manipulatives. One possible reason for this is that instruction has failed to apply Gestalt principles of perceptual organization to the lesson materials. To see if fourth grade students' understanding could be improved, four lessons were designed and taught using the Gestalt laws of Figure-Ground, Symmetry, and Similarity. Students (n = 54) who were taught lessons applying the Gestalt principles scored 12% higher on an assessment than students (n = 51) who only were taught lessons using the traditional methods. Though scores showed significant improvement, it is recommended to follow the American Association for the Advancement of Science guidelines and wait until 9th grade to instruct students about the phases.

  5. Calibration Lessons Learned from Hyperion Experience

    The use of hyperspectral imagers to provide climate-quality data sets, such as those expected from the solar reflective sensor on the Climate Absolute Radiance and Refractivity Observatory (CLARREO), requires stringent radiometric calibration requirements. These stringent requirements have been nearly met with broadband radiometers such as CERES, but high resolution spectrometers pose additional challenges. A review of the calibration processes for past space-based HSIs provide guidance on the calibration processes that will be needed for future sensors. In November 2000, the Earth Observer-1 (EO-1) platform was launched onboard a Boeing Delta II launch vehicle. The primary purpose of the EO-1 mission was to provide a technological testbed for spaceborne components. The platform has three sensors onboard, of which, the hyperspectral imager (HSI) Hyperion, is discussed here. The Hyperion sensor at the time had no comparable sensor in earth orbit, being the first grating-based, hyperspectral, civilian sensor in earth orbit. Ground and on-orbit calibration procedures including all cross-calibration activities have achieved an estimated instrument absolute radiometric error of 2.9% in the Visible channel (0.4 - 1.0 microns) and 3.4% in the shortwave infrared (SWIR, 0.9 - 2.5 microns) channel (EO-1/Hyperion Early Orbit Checkout Report Part II On-Orbit Performance Verification and Calibration). This paper describes the key components of the Hyperion calibration process that are applicable to future HSI missions. The pre-launch methods relied on then newly-developed, detector-based methods. Subsequent vicarious methods including cross-calibration with other sensors and the reflectance-based method showed significant differences from the prelaunch calibration. Such a difference demonstrated the importance of the vicarious methods as well as pointing to areas for improvement in the prelaunch methods. We also identify areas where lessons learned from Hyperion regarding

  10. Incorporating climate change and technology into the science classroom: Lessons from my year as a GK-12 Fellow

    Science.gov (United States)

    Abramoff, R. Z.

    2012-12-01

    Climate change is not included in the K-8 science standards in Massachusetts; as a result, students learn what climate is, but not how human activities affect it. Starting in 2010, Boston University launched the GK-12 GLACIER program, funded with 2.9M from the National Science Foundation. The purpose of the program is to incorporate the fundamentals of climate change into the K-12 curriculum, focusing on grades 5-8 when quantitative science enters the curriculum. Graduate students are partnered with teachers in Boston public schools for 10 hours a week of teaching with additional curriculum development. I will focus on the curriculum that I developed as a part of this program for the 5th grade science class at The Curley School in Jamaica Plain, MA, where I worked with Grades 3-5, ESL, and PACE autism program science teacher, Stephanie Selznick. The Curley School is an ethnically and economically diverse Boston public school with about 800 students and an 83% minority population. At the Curley, I taught two full days a week, meeting with all of the 5th grade classes and some of the 4th grade classes of all academic levels. The lessons that I created were designed to fit into the state standards and enrich student understanding plant ecology and earth science, as well as develop their capacity to design experiments and use technology. These include Question of the Day, Digital Field Guide to the Outdoor Classroom, Phototropism, Solar System Weather Report, Soil and Water, Local Landforms, and the Earth as a Closed System Unit for which materials and lesson plans are available on my website. Our secondary goals were to improve tech literacy at Curley. Due to funding restrictions, there were few technology resources available to the students at the beginning of the 2011/2012 school year. To improve technology resources at Curley, I organized a fundraiser at Boston University, selling donated items from graduate students and faculty; the 1000 raised was used to supply

    2015-10-01

    While directing the Future of Nursing: Campaign for Action, Susan B. Hassmiller, the Robert Wood Johnson Foundation's senior adviser for nursing, realized the value that nursing history could bring to the campaign. She decided to interview her mother, Jacqueline J. Wouwenberg, a 1947 graduate of the Bellevue Hospital School of Nursing, in order to better understand and contextualize changes that had occurred in the nursing profession during the 20th century. In collaboration with nurse historians Cathryne A. Welch and Sandra B. Lewenson, Hassmiller participated in interviewing her mother and was also interviewed herself. The stories that emerged revealed a great deal: each woman had found that nursing had given them countless opportunities that reflected the time periods in which they lived. Wouwenberg's experiences, transmitted to Hassmiller through words and actions, also served as important lessons for her daughter. This article shares five lessons: be independent and courageous, know that nursing has no bounds, follow your passion, honor diversity, and give back. It also asks readers to reflect on the relevance of nurses' work from one generation to the next..

    Hatamura, Yotaro

    2013-01-01

    Through the investigation of the Fukushima Nuclear Power Accident as the chairman of the related Government's Committee, many things had been considered. Essence of the accident could be not only what occurred in the Fukushima nuclear power station, but also dispersed radioactive materials forced many residents to move and not to be returned. Such events as indication errors of water level meter occurring in severe accident could no be thought and remote mechanical operation of valves under high radiation environment were not prepared. Contamination by radioactive clouds caused the evacuation of residents for a long period. Lessons learned from the accident were described such as; (1) the verification of the road to failure connecting selected accident sequence and road to success with another supposed choice, (2) considering what might occur and then what should be needed on the contrary, (3) nuclear power, if should be continued, should be used with the premise of its hazards, and (4) advise to nuclear engineer for adequate information dissemination and technical explanation to the public and keeping nuclear technologies alive.

    1996-12-01

    The purpose of this generic aging lessons learned (GALL) review is to provide a systematic review of plant aging information in order to assess materials and component aging issues related to continued operation and license renewal of operating reactors. Literature on mechanical, structural, and thermal-hydraulic components and systems reviewed consisted of 97 Nuclear Plant Aging Research (NPAR) reports, 23 NRC Generic Letters, 154 Information Notices, 29 Licensee Event Reports (LERs), 4 Bulletins, and 9 Nuclear Management and Resources Council Industry Reports (NUMARC IRs) and literature on electrical components and systems reviewed consisted of 66 NPAR reports, 8 NRC Generic Letters, 111 Information Notices, 53 LERs, 1 Bulletin, and 1 NUMARC IR. More than 550 documents were reviewed. The results of these reviews were systematized using a standardized GALL tabular format and standardized definitions of aging-related degradation mechanisms and effects. The tables are included in volume s 1 and 2 of this report. A computerized data base has also been developed for all review tables and can be used to expedite the search for desired information on structures, components, and relevant aging effects. A survey of the GALL tables reveals that all ongoing significant component aging issues are currently being addressed by the regulatory process. However, the aging of what are termed passive components has been highlighted for continued scrutiny. This document is Volume 1, consisting of the executive summary, summary and observations, and an appendix listing the GALL literature review tables.

    In July 1995, the CE Owner's Group completed and issued Revision 0 of the Generic Accident Management Guidelines (AMG's) to the owners group task participants. This guidance provides a structured mechanism for the plant staff at CE utilities to respond to accidents that beyond the plant design basis and, possibly, the Emergency Operating Procedures. Prior to final issue of the generic AMGs, the CEOG conducted an AMG Confirmation Exercise to establish the ability of the AMGs to fulfill this important role. The specific objectives of the AMG Confirmation Exercise were to (1) clarify the interactions and transitions between the AMG/Technical Support Center (TSC) and the EOPS/Operations Personnel (2) validate the adequacy of the AMG data collection and plant condition diagnostic evaluation process and (3) assess the feasibility of the mechanical material and recommendations contained in the AMG's. The purpose of paper is to provide a detailed description of the AMG Confirmation Exercise as well as important lessons learned during the planning and implementation of the exercise. In addition, a discussion will be presented pertaining to the relationship between the AMG's (incumbent to the Technical Support Center) and the plants Emergency Operating Procedures (incumbent to the Control Room Operations Staff)

    Zigon, Thomas

    1999-01-01

    The outreach and education components of the International Space Station Program are creating a number of materials, programs, and activities that educate and inform various groups as to the implementation and purposes of the International Space Station. One of the strategies for disseminating this information to K-12 students involves an electronic class room using state of the art video conferencing technology. K-12 classrooms are able to visit the JSC, via an electronic field trip. Students interact with outreach personnel as they are taken on a tour of ISS mockups. Currently these events can be generally characterized as: Being limited to a one shot events, providing only one opportunity for students to view the ISS mockups; Using a "one to many" mode of communications; Using a transmissive, lecture based method of presenting information; Having student interactions limited to Q&A during the live event; Making limited use of media; and Lacking any formal, performance based, demonstration of learning on the part of students. My project involved developing interactive lessons for K-12 students (specifically 7th grade) that will reflect a 2nd generation design for electronic field trips. The goal of this design will be to create electronic field trips that will: Conform to national education standards; More fully utilize existing information resources; Integrate media into field trip presentations; Make support media accessible to both presenters and students; Challenge students to actively participate in field trip related activities; and Provide students with opportunities to demonstrate learning

    The purpose of this generic aging lessons learned (GALL) review is to provide a systematic review of plant aging information in order to assess materials and component aging issues related to continued operation and license renewal of operating reactors. Literature on mechanical, structural, and thermal-hydraulic components and systems reviewed consisted of 97 Nuclear Plant Aging Research (NPAR) reports, 23 NRC Generic Letters, 154 Information Notices, 29 Licensee Event Reports (LERs), 4 Bulletins, and 9 Nuclear Management and Resources Council Industry Reports (NUMARC IRs) and literature on electrical components and systems reviewed consisted of 66 NPAR reports, 8 NRC Generic Letters, 111 Information Notices, 53 LERs, 1 Bulletin, and 1 NUMARC IR. More than 550 documents were reviewed. The results of these reviews were systematized using a standardized GALL tabular format and standardized definitions of aging-related degradation mechanisms and effects. The tables are included in volumes 1 and 2 of this report. A computerized data base has also been developed for all review tables and can be used to expedite the search for desired information on structures, components, and relevant aging effects. A survey of the GALL tables reveals that all ongoing significant component aging issues are currently being addressed by the regulatory process. However, the aging of what are termed passive components has been highlighted for continued scrutiny. This document is Volume 1, consisting of the executive summary, summary and observations, and an appendix listing the GALL literature review tables

  8. Linguistic aspects of writing for professional purposes

    Directory of Open Access Journals (Sweden)

    Greta Përgjegji

    2016-03-01

    Full Text Available Writing for Professional Purposes is considered as a means of communication between professionals who belong to two communities that have different languages, but share the same knowledge or expertise. The article gives a hint on how writing for specific purposes evolved to give rise to the creation of Writing for Professional Purposes. The social, cultural and cognitive aspects are an essential part of Writing for Professional Purposes since the physical act of writing cannot be considered only a result or product of the knowledge the individual possesses but also a social and cultural act. Therefore, the social and cultural aspects of writing explains the specificities and the intricacies of the effects these aspects have on writing for it is considered as an inseparable part of social and cultural groups. On the other hand, the cognitive aspect of writing explains and emphasizes the mental activities of the individual during the decision-making process while he/she is writing planning and editing their material having in mind the audience. On the same line of reasoning, writing for professional purposes in a second language means that the writer has to consider the audience twice; first, there is an audience who shares the same knowledge or expertise and second, the audience does not have the same language. Consequently, writing in another language that is not the first language with a specific jargon as well as a specific grammatical structure brings about a lot of difficulties. Hence, writing in professional contexts in the mother tongue implies only writing in a specialized version of a language already known to the writer, but writing in a target language means that the writer has to learn the target language and the specialized version of that language.

    semi-custodial state as an active safe enclosure strategy. As a result of continued occupancy and re-purposing some of the buildings post shutdown, most of the building services including heating, ventilation, water and fire detection systems at the Douglas Point site have been maintained operational. With the exception of the fuel canister area, security is maintained as access control for the multi facility site. The Gentilly-1 Nuclear Generating Station was put into service in 1972. It consisted of a 250 MW CANDU- BWR experimental reactor located in Beancour, Quebec on a shared site with the Gentilly-2 Nuclear Generating Station (owned by Hydro Quebec). Following issues in attaining a full operational status, the reactor was put into a lay-up state in 1980 and permanently shutdown in 1982. The Gentilly-1 site is maintained with a safe enclosure strategy primarily in a 'Cold and Quiet' state with all ventilation and heating systems shutdown. However, a dehumidifier is installed to maintain the moisture levels within the reactor building envelope. Fire detection is limited to areas of concern and, with the exception of the canister area, security is maintained for access control to a multi-facility site. Lesson learned from the deferred decommissioning strategy on the maintenance of existing building structures and associated storage facilities while we allow for decay of the radioactive materials; the impact on costs and other associated factors will be explored. This paper will discuss the lesson learned from shutdown strategies and the impact of these strategies on the safe enclosure period through to decommissioning as it was employed at the three Canadian prototype power reactor sites. Topics will include the advantages and drawbacks, as well as, the repercussions of these strategies, due to the extended shut down periods which affect shut down operating costs, life management strategies, regulatory implications and progression into the final

  10. The Use of Lesson Study Combined with Content Representation in the Planning of Physics Lessons During Field Practice to Develop Pedagogical Content Knowledge

    Science.gov (United States)

    Juhler, Martin Vogt

    2016-08-01

    Recent research, both internationally and in Norway, has clearly expressed concerns about missing connections between subject-matter knowledge, pedagogical competence and real-life practice in schools. This study addresses this problem within the domain of field practice in teacher education, studying pre-service teachers' planning of a Physics lesson. Two means of intervention were introduced. The first was lesson study, which is a method for planning, carrying out and reflecting on a research lesson in detail with a learner and content-centered focus. This was used in combination with a second means, content representations, which is a systematic tool that connects overall teaching aims with pedagogical prompts. Changes in teaching were assessed through the construct of pedagogical content knowledge (PCK). A deductive coding analysis was carried out for this purpose. Transcripts of pre-service teachers' planning of a Physics lesson were coded into four main PCK categories, which were thereafter divided into 16 PCK sub-categories. The results showed that the intervention affected the pre-service teachers' potential to start developing PCK. First, they focused much more on categories concerning the learners. Second, they focused far more uniformly in all of the four main categories comprising PCK. Consequently, these differences could affect their potential to start developing PCK.

  11. Lesson study: Professional development and its impact on science teacher self-efficacy

    Science.gov (United States)

    Roberts, Megan Rae

    This study focuses on an analysis of a professional development program known as lesson study via data obtained during an in-service professional development program for secondary school science teachers. The purpose of this study was to examine the self-efficacy beliefs of one group of science teachers related to their experiences in a lesson study. Another purpose for this research, aligned with the first, included a theoretical analysis of the lesson study construct to see if its design promoted positive self-efficacy beliefs of its participants. The research is framed within the context of social constructivism and self-efficacy and is qualitative in nature and utilized descriptive analysis as a means of research. Case studies were conducted detailing two of the six participants. Data sources included researcher field notes and transcriptions of all planning and debriefing sessions; individual interviews with each participant and the schools' principal; a participant questionnaire, and the Science Teaching Efficacy Belief Instrument. Themes that emerged included the positive perceptions of lesson study as a collaborative and teacher-centered experience; the understanding that lesson study can instill a sense of professionalism to those who participate in the process; the sense that discussing student learning using objective observations from classroom is a powerful way to assess learning and uncover personal teacher beliefs; and the insight that the time commitment that lesson study requires can inhibit teachers and schools from sustaining it as a form of on-going professional development. Although these themes are consistent with the research on lesson study in Japan and elsewhere in the United States, they also extend the research on self-efficacy and science teacher professional development. In the end, this study supported some of the conclusions of the self-efficacy research as it relates to professional development while also adding that interpersonal

  12. Health communication: lessons from research.

    Science.gov (United States)

    Shanmugam, A V

    1981-01-01

    In discussing the lessons learned from research in the area of health communication, focus is on basic strategic issues; the scope of health communications in terms of audience, information, education and motivation approaces and India's satellite Instructional Television Experiment (SITE). Health communication is the process by which a health idea is transferred from a source, such as a primary health center, to a receiver, community, with the intention of changing the community's behavior. This involves the formulation of specific strategies for the conduct of health and family welfare communication. In the processs of health communication, it has been a common practice in India as well as in other developing countries to depend upon a plethora of communication media. Yet, despite maximum utilization of the mass media and interpersonal channels of communication, questions remain about the efficacy of the system in bringing about change. Thus, the need to draw upon lessons from research becomes obvious. Communication effectiveness researches have concentrated on 3 basic strategic issues: the question of physical reception of messages by the audience; interpretation or understanding of messages on the part of the audience in accordance with the intention of the communicator; and effectiveness of communication on the cognitive, affective and behavioral dimensions of the audience. Innumberable researches in communication have provided several lessons which have expanded the scope of health communication. This expansion can be observed in terms of audiences reached, information disseminated, education undertaken, and motivation provided. Research has identified several distinct groups to whom specific health messages have to be addressed. These include government and political elites, health and family welfare program administrators, and the medical profession and clinical staff. Information on health needs to include both the concept of health and the pertinent ideas

    Full text: Malaysia Decommissioning of Naturally Occurring Radioactive Materials (NORM) facility in Malaysia will run into unforeseeable complications and difficulties if there is no proper planning. The Atomic Energy Licensing Board (AELB) plays important role in guiding and assisting the operator/contractor in this NORM decommissioning project. A local Naturally Occurring Radioactive Materials (NORM) processing plant located in the northern region of peninsular Malaysia had ceased its operations and decided to decommission and remediate its site for the final release of the site. The remediated site is earmarked as an industrial site. During its operations, monazites are processed for rare earth elements such as cerium and lanthanum. It's plant capable of processing monazite to produce rare earth chloride and rare earth carbonate. The main by-product of monazite processing is the radioactive cake containing primarily thorium hydroxide. Operation of the monazite processing plant started in early eighties and terminated in early nineties. The decommissioning of the plant site started in late 2003 and completed its decommissioning and remediation works in early 2006. This paper described the lesson learned by Malaysian Nuclear Agency (Nuclear Malaysia) in conducting third party independent audit for the decommissioning of the NORM contaminated facility. By continuously reviewing the lessons learned, mistakes and/or inefficiencies in this plant decommissioning project, hopefully will result in a smoother, less costly and more productive future decommissioning works on NORM facilities in Malaysia.

    Full Text Available The history of World War I is reviewed, starting with a discussion of the development of nationalist movements in Europe. It is pointed out that the global disaster started with a seemingly small operation by Austria, which escalated uncontrollably into an all-destroying conflagration. A striking feature of the war was that none of the people who started it had any idea of what it would be like. Technology had changed the character of war, but old patterns of thought remained in place. We also examine the roots of the war in industrial and colonial competition, and in an arms race. Finally, parallels with current events, and the important lessons for today’s world are discussed.

    Meyer, M.B.

    1984-01-01

    Principal explanations for the WPPSS events to date can be more or less satisfactorily derived. Five explanations appear to dominate: (1) the long and previously successful history of public power in the Pacific Northwest; (2) overoptimism by architect/engineers and consulting engineers about construction costs and construction durations; (3) laxness by bond counsel in scrutinizing and disclosing potential legal impediments to the various transactions involved; (4) WPPSS easy access to capital markets, combined with naivete in those markets; and (5) the inability of WPPSS to manage and oversee the construction process. This paper explains the specific reasons for, and the importance of, each of these five explanations for the WPPSS debacle. It then develops lessons and conclusions for the future which can be derived from this debacle. 12 references

    This paper presents a study performed by the European Clearinghouse of the Joint Research Centre on Operational Experience for nuclear power plants in cooperation with IRSN and GRS covering events reported by nuclear power plants in relation to external hazards. It summarizes the review of 235 event reports from 3 different databases. The events were grouped in 9 categories according to the nature of the external hazard involved, and the specific lessons learned and recommendations that can be derived from each of these categories are presented. Additional 'cross-cutting' recommendations covering several or all the external hazards considered are also discussed. These recommendations can be useful in preventing this type of events from happening again or in limiting their consequences. The study was launched in 2010 and therefore it does not cover the Fukushima event. This paper presents the main findings and recommendations raised by this study. (orig.)

Seven surgical cases. Institutional review of errors committed and subsequent improvements to clinical protocols. Lessons learned and changes in procedures adapted. The pathways to a wrong IOL are many but largely reflect some combination of poor surgical team communication, transcription error, lack of preoperative clarity in surgical planning or failure to match the patient, and IOL calculation sheet with 2 unique identifiers. Safety in surgery involving IOLs is enhanced both by strict procedures, such as an IOL-specific "time-out," and the fostering of a surgical team culture in which all members are encouraged to voice questions and concerns.

    1987-09-01

    Emergency preparedness at nuclear power plants in the US has been considerably enhanced since the Three Mile Island accident. The Chernobyl accident has provided valuable data that can be used to evaluate the merit of some of these enhancements and to determine the need for additional improvements. For example, the USSR intervention levels of 25 rem and 75 rem for evacuation are contrasted with US Environmental Protection Agency protective action guides. The manner in which 135,000 persons were evacuated from the 30-km zone around Chernobyl is constrasted with typical US evacuation plans. Meteorological conditions and particulate deposition patterns were studied to infer characteristics of the radioactive plume from Chernobyl. Typical plume monitoring techniques are examined in light of lessons learned by the Soviets about plume behavior. This review has indicated a need for additional improvements in utility and government emergency plans, procedures, equipment, and training. 12 refs., 1 fig., 2 tabs

  9. Lessons Learned from Arsenic Mitigation among Private Well Households

    Science.gov (United States)

    2018-01-01

    Purpose of Review Many thousands of research papers have been published on the occurrence, health effects, and mitigation of arsenic in drinking water sourced from groundwater around the world. Here, an attempt is made to summarize this large body of knowledge into a small number of lessons. Recent Findings This is an opinion paper reflecting on why we are far from the goal of eliminating this silent and widespread poison to protect the health of many millions. The lessons are drawn from research in countries representing a range of economic development and cultural contexts. The replacement of household wells with centralized water supplies has reduced population level exposure to moderate (50–100 μg/L) and high (>100 μg/L) levels of arsenic in drinking water in some countries as they become wealthier. However, there remains a very large rural population in all countries where the exposure to low levels (10–50 μg/L) of arsenic continues due to its dispersed occurrence in the environment and frequent reliance on private well. A set of natural (geological and biological), socioeconomic, and behavioral barriers to progress are summarized as lessons. They range from challenges in identifying the exposed households due to spatially heterogeneous arsenic distribution in groundwater, difficulties in quantifying the exposure let alone reducing the exposure, failures in maintaining compliance to arsenic drinking water standards, to misplaced risk perceptions and environmental justice issues. Summary Environmental health professionals have an ethical obligationtohelpAsmitigationamongprivatewellwaterhouse-holds, along with physicians, hydrogeologists, water treatment specialists, community organizations, and government.

    Moore, T.L.; Titzler, P.A.

    1994-01-01

    An emergency task was undertaken to remove four air lances and one thermocouple (TC) tree from tank 241-SY-101 (SY-101). This resulted from video observation that these pipes were being severely bent during periodic gas release events that regularly occurred every three to four months. At the time, the gas release events were considered to be the number one safety issue within the US Department of Energy (DOE) complex. This emergency removal task was undertaken on an extremely short schedule that required all activities possible to be completed in parallel. This approach and extremely short schedule, while successful, resulted in some undesirable consequences from less than desired time for design, reviews, equipment testing, operations training, and bad weather conditions. These consequences included leakage of liquid waste from the containers to the ground, higher than expected dose rates at the container surface, difficult field operations, and unexpected pipe configuration during removal. In addition, changes to environmental regulations and severe winter weather impacted the packaging and shipping activities required the prepare the removed pipes for storage at the Central Waste Complex (CWC). The purpose of this document is to identify lessons to be learned for future activities. In context of the emergency conditions that existed at the time and the urgency to remove these pipes, their removal was successfully completed under extremely difficult conditions and schedule. The success of the task should not be overshadowed by the desire to identify areas needing improvement and lessons to be learned. Many of the lessons identified in this document have already resulted in improved conduct of operations and engineering

  14. Lessons learned from accidental exposures in radiotherapy

    International Nuclear Information System (INIS)

    2000-01-01

    The medical use of radiation is unique in that patients are intentionally exposed to radiation. The aim in radiation therapy is twofold: to deliver a dose and dose distribution that is adequate for tumour control, but which also minimizes complications in normal tissues. In therapeutic applications, the doses are high and a deviation from the prescribed dose may have severe or even fatal consequences. There is therefore a great need to ensure adequate radiation protection and safety in radiotherapy by verifying that all personnel involved are appropriately trained for their duties, that the equipment used meets relevant international specifications for radiation safety and that safety culture is embedded in routine activities in radiotherapy departments. Many individuals must interact and work together on highly technical measurements and calculations, and therefore the potential for mistakes is great. A review of the mistakes shows that most are due to human error. The International Basic Safety Standards for Protection against Ionizing Radiation and the Safety of Radiation Sources (IAEA Safety Series No. 115) require that a prompt investigation be conducted whenever an accidental medical exposure of patients occurs. The report of the investigation is to be disseminated to the appropriate parties so that lessons can be learned to prevent similar accidents or mitigate their consequences in the future. This Safety Report is a collection of a large number of events that may serve as a checklist against which to test the vulnerability of a facility to potential accidents, and to provide a basis for improving safety in the use of radiation in medical applications. A further purpose of this report is to encourage readers to develop a questioning and learning attitude, adopt measures for the prevention of accidents, and prepare for mitigation of the consequences of accidents if they occur

  9. Experience and lessons learnt from clearance in Germany

    International Nuclear Information System (INIS)

    Thierfeldt, Stefan

    2002-01-01

    Clearance is an important corner-stone of waste management in nuclear installations in Germany. It has been practised successfully for around two decades. The importance of clearance can also be judged from the fact that it has been included detailedly in the new German Radiation Protection Ordinance. Currently, there are 19 NPPs and a number of fuel cycle installations in operation in Germany. The main waste quantities, however, arise from the dismantling of NPPs and fuel cycle installations which are currently in decommissioning. As most of the decommissioning projects are targeted for early dismantling instead of safe enclosure, there is already considerable experience with the application of clearance procedures and verification of clearance levels. The German waste management strategy is governed by two options: Clearance of the material (after decontamination and release measurement). After clearance, the material is no longer regarded as radioactive in a legal sense. Final disposal of the material as radioactive waste in a deep geological repository (no near-surface disposal facilities exist or are planned in Germany). A deep geological repository is planned to be operable around 2030. Stefan Thierfeldt described German clearance requirements and lessons learned from their application to decommissioning of power reactors. The great majority of the waste was in fact recycled, although the costs were dominated by the small fraction that had to be disposed of as radioactive waste. Among the lessons learned from the German experience were some revealing insights into the public perception of both clearance and of recycling of material from decommissioning of a nuclear installation

    2017-09-01

    Science teachers are being called on to incorporate engineering practices into their classrooms. This study explores whether the Engineering-Infused Lesson Rubric, a new rubric designed to target best practices in engineering education, could be used to evaluate the extent to which engineering is infused into online science lessons. Eighty lessons were selected at random from three online repositories, and coded with the rubric. Overall results documented the strengths of existing lessons, as well as many components that teachers might strengthen. In addition, a subset of characteristics was found to distinguish lessons with the highest level of engineering infusion. Findings are discussed in relation to the potential of the rubric to help teachers use research evidence-informed practice generally, and in relation to the new content demands of the U.S. Next Generation Science Standards, in particular.

    2006-07-01

    In this progress report prepared for the Swiss Federal Office of Energy (SFOE) the feasibility of realizing a multipurpose vehicle for municipalities has been studied. The vehicle consists of a single driving unit equipped with an interchangeable top cell. Depending on the required use, this cell may be for transporting children, disabled persons or different materials, like e.g. green wastes, waste paper or PET bottles. In order to make the access for children and disabled people easier the cell can be moved in the vertical direction. A hybrid motorization is proposed comprising a combustion engine powering the front wheels and an electric motor powering the rear wheels. Depending on the conditions of use, the resulting energy consumption is about 15 % lower than for a vehicle equipped with a combustion engine only.

    Full Text Available The purpose of the present study was to compare the effects of two different teaching methods on students' comprehension during Physical Education lesson: narration versus animation with concurrent narration, during teaching shot put event. Thirty primary school children (boys and girls volunteered to participate in this study. In experiment students listened (narration and viewed (animation with narration the presentation of two shot putting styles. A problem-solving and a retention test were used to evaluate students' comprehension. Results showed that students' comprehension was better when shot putting styles were presented through a mixed model (animation and narration group than a single (narration. The animation with concurrent narration group performed better than the narration group, in problem-solving (M = 4.91, SD = 1.36 and in retention test (M = 5.98, SD = 1.28 t(28 = 1.89 p<0.01. An instructional implication is that pictures with words is more effective way of teaching when they occur continuingly in time, than only words during Physical Education lesson.

  13. Massachusetts nuclear power referendum: Lessons learned from the campaign trail

    International Nuclear Information System (INIS)

    Allen, S.R.

    1989-01-01

    Last November, Massachusetts voters cast their ballots on a binding initiative which, if passed, would have prohibited the production of high-level waste, thereby permanently shutting down the state's two nuclear power plants: Yankee and Pilgrim. Question 4, as the initiative became known, posed an unprecedented challenge for the state's six major utilities. Essentially, Question 4 was defeated for two reasons: compelling arguments and a well-founded strategy for communicating those arguments. One part of that strategy was the use of debates and public-speaking engagements before both civic groups and on radio/television. These debates and presentations were clearly the most interesting part of the campaign and provided many insights that may be applied to long-term public policy and informational programs. Obviously, there is a significant difference between an intense, focused campaign and an ongoing, diverse public information program-but many of the principles are the same. The purpose of this paper is to review some of the key lessons learned from over 300 debates and presentations in the highly emotional atmosphere of the Question 4 campaign. Throughout the campaign, debaters and speakers submitted after action reports, and it is from these as well as the overall campaign results that the lessons and anecdotes are derived

    Emrich, Bill

    2008-01-01

    The General Purpose Heat Source (GPHS) simulator project is designed to replicate through the use of electrical heaters, the form, fit, and function of actual GPHS modules which generate heat through the radioactive decay of Pu238. The use of electrically heated modules rather than modules containing Pu238 facilitates the testing of spacecraft subsystems and systems without sacrificing the quantity and quality of the test data gathered. Previous GPHS activities are centered around developing robust heater designs with sizes and weights that closely matched those of actual Pu238 fueled GPHS blocks. These efforts were successful, although their maximum temperature capabilities were limited to around 850 C. New designs are being pursued which also replicate the sizes and weights of actual Pu238 fueled GPHS blocks but will allow operation up to 1100 C.

    In today's world, the security became the major issue to every human being. A major issue is hacking as hackers are everywhere, as the technology was developed still there are many issues where the technology fails to meet the security. Engineers, scientists were discovering the new products for security purpose as biometrics sensors like face recognition, pattern recognition, gesture recognition, voice authentication etcetera. But these devices fail to reach the expected results. In this work, we are going to present an approach to generate a unique secure key using the iris template. Here the iris templates are processed using the well-defined processing techniques. Using the encryption and decryption process they are stored, traversed and utilized. As of the work, we can conclude that the iris cryptography gives us the expected results for securing the data from eavesdroppers.

  19. Saliva Preservative for Diagnostic Purposes

    Science.gov (United States)

    Pierson, Duane L.; Mehta, Satish K.

    2012-01-01

    Saliva is an important body fluid for diagnostic purposes. Glycoproteins, glucose, steroids, DNA, and other molecules of diagnostic value are found in saliva. It is easier to collect as compared to blood or urine. Unfortunately, saliva also contains large numbers of bacteria that can release enzymes, which can degrade proteins and nucleic acids. These degradative enzymes destroy or reduce saliva s diagnostic value. This innovation describes the formulation of a chemical preservative that prevents microbial growth and inactivates the degradative enzymes. This extends the time that saliva can be stored or transported without losing its diagnostic value. Multiple samples of saliva can be collected if needed without causing discomfort to the subject and it does not require any special facilities to handle after it is collected.

  8. How to learn and develop from both good and bad lessons- the 2011Tohoku tsunami case -

    Science.gov (United States)

    Sugimoto, Megumi; Okazumi, Toshio

    2013-04-01

    The 2011 Tohoku tsunami revealed Japan has repeated same mistakes in a long tsunami disaster history. After the disaster Japanese remember many old lessons and materials: an oral traditional evacuation method 'Tsunami TENDENKO' which is individual independent quick evacuation, a tsunami historical memorial stone "Don't construct houses below this stone to seaside" in Aneyoshi town Iwate prefecture, Namiwake-shrine naming from the story of protect people from tsunami in Sendai city, and so on. Tohoku area has created various tsunami historical cultures to descendent. Tohoku area had not had a tsunami disaster for 50 years after the 1960 Chilean tsunami. The 2010 Chilean tsunami damaged little fish industry. People gradually lost tsunami disaster awareness. At just the bad time the magnitude (M) 9 scale earthquake attacked Tohoku. It was for our generations an inexperienced scale disaster. People did not make use of the ancestor's lessons to survive. The 2004 Sumatra tsunami attacked just before 7 years ago. The magnitude scale is almost same as M 9 scale. Why didn't Tohoku people and Japanese tsunami experts make use of the lessons? Japanese has a character outside Japan. This lesson shows it is difficult for human being to learn from other countries. As for Three mile island accident case in US, it was same for Japan. To addition to this, there are similar types of living lessons among different hazards. For examples, nuclear power plantations problem occurred both the 2012 Hurricane Sandy in US and the 2011 Tohoku tsunami. Both local people were not informed about the troubles though Oyster creek nuclear power station case in US did not proceed seriously all. Tsunami and Hurricane are different hazard. Each exparts stick to their last. 1. It is difficult for human being to transfer living lessons through next generation over decades. 2. It is difficult for human being to forecast inexperienced events. 3. It is usually underestimated the danger because human being

  9. Modular and extensible lesson on fiber optics for youths

    Wong, Nicholas H. L.; Tong, Amy S. K.; Posner, Matthew T.; Ravagli, Andrea

    2017-08-01

    Fiber optics and its application in telecommunications are rarely encountered by students until they reach tertiary education. While some secondary/middle school curricula may include coverage of basic geometrical optics concepts such as reflection and refraction, few if any go further to elaborate on how these eventually relate to global telecommunications. One could say that the science is made accessible for early-stage students, but discussions about applications are often reserved till later stages. In working through a PhD student-led optics educational outreach program called the "Lightwave Roadshow", we have observed, via engagements with young students and the public at school visits and fairs, that many youths (as well as parents) do have a basic appreciation that the internet is somehow based on light signals. However, few know how the two are related, much less how they work. To address this, our team of `ambassadors' in the Lightwave program has designed a self-contained lesson to introduce youths, aged 11 to 18 years, to fiber optics and optical fiber communications, drawing inspiration from various educational resources such as LASER ClassroomTM and the Exploratorium(R). The lesson is modularized into several parts, starting with using light to communicate Morse code, and then going into advanced concepts, such as total internal reflection and multiuser communications based on wavelength-division multiplexing. The latter can be treated as extensions whose inclusion can be tailored based on the youths' educational levels. A feature of this lesson is that it takes amore phenomenological than theoretical approach, and uses materials that are easily obtainable or craftable as well as interesting for youths, including colored gelatin, LED sources, and water as a waveguide. We outline a lesson and pedagogical method which contains hands-on experiments that can be carried out by educators in formal or informal classes, students learning independently, or

    1993-07-01

    This report describes a workshop designed to introduce participants to a process, or model, for adapting LWR Safety Standards and Analysis Methods for use on rector designs significantly different than LWR. The focus of the workshop is on the ''Lessons Learned'' from the multi-year experience in the operation of N Reactor and the efforts to adapt the safety standards developed for commercial light water reactors to a graphite moderated, water cooled, channel type reactor. It must be recognized that the objective of the workshop is to introduce the participants to the operation of a non-LWR in a LWR regulatory world. The total scope of this topic would take weeks to provide a through overview. The objective of this workshop is to provide an introduction and hopefully establish a means to develop a longer term dialogue for technical exchange. This report provides outline of the workshop, a proposed schedule of the workshop, and a description of the tasks will be required to achieve successful completion of the project

    Shiltsev, V.

    2011-01-01

    For almost a quarter of a century, the Tevatron proton-antiproton collider was the centerpiece of the world's high energy physics program - beginning operation in December of 1985 until it was overtaken by LHC in 2011. The aim of the this unique scientific instrument was to explore the elementary particle physics reactions with center of mass collision energies of up to 1.96 TeV. The initial design luminosity of the Tevatron was 10 30 cm -2 s -1 , however as a result of two decades of upgrades, the accelerator has been able to deliver 430 times higher luminosities to each of two high luminosity experiments, CDF and D0. Tevatron will be shut off September 30, 2011. The collider was arguably one of the most complex research instruments ever to reach the operation stage and is widely recognized for many technological breakthroughs and numerous physics discoveries. Below we briefly present the history of the Tevatron, major advances in accelerator physics, and technology implemented during the long quest for better and better performance. We also discuss some lessons learned from our experience.

    Kerns, K.C.

    1994-03-01

    FRMAC-93 simulated a radiological accident at the Fort Calhoun nuclear power plant, 25 miles north of Omaha, Nebraska. The exercise involved the state Iowa and Nebraska, NRC as the lead Federal agency, FRMAC (Federal Radiological Monitoring and Assessment Center), and several federal agencies with statutory emergency responsibility. FRMAC-93 was a major 2-day field exercise designed to determine the effectiveness, coordination, and operations of a DOE-managed FRMAC. Other objectives were to ensure that appropriate priorities were established and assistance was provided to the states and the lead Federal agency by FRMAC. Day 1 involved the Fort Calhoun evaluated plume phase exercise. On Day 2, the flow of data, which was slow initially, improved so that confidence of states and other federal responders in FRMAC support capabilities was high. The impact and lessons learned from FRMAC-93 provided the necessary impetus to make organizational and operational changes to the FRMAC program, which were put into effect in the DOE exercise FREMONT at Hanford 3 months later

    Werner, K.

    2013-12-01

    Following Hurricane Sandy's impact on the mid-Atlantic region, President Obama established a Task Force to '...ensure that the Federal Government continues to provide appropriate resources to support affected State, local, and tribal communities to improve the region's resilience, health, and prosperity by building for the future.' The author was detailed from NOAA to the Task Force between January and June 2013. As the Task Force and others began to take stock of the region's needs and develop plans to address them, many diverse approaches emerged from different areas of expertise including: infrastructure, management and construction, housing, public health, and others. Decision making in this environment was complex with many interests and variables to consider and balance. Although often relevant, science and technical expertise was not always at the forefront of this process. This talk describes the author's experience with the Sandy Task Force focusing on organizing scientific expertise to support the work of the Task Force. This includes a description of federal activity supporting Sandy recovery efforts, the role of the Task Force, and lessons learned from developing a science support function within the Task Force.

  14. Transboundary Movement of Radioactively Contaminated Scrap Metal - Lessons Learned

    Energy Technology Data Exchange (ETDEWEB)

    Starting in 1989, Bulgaria has undergone a comprehensive transformation of its economy and social conditions. Part of this process is related to the intensive privatization that started in 2001. This privatization included facilities, as well as sites that use radioactive material for different applications - industry, medicine, agriculture, science, etc. The rapid change of property ownership and, in some cases, the resulting bankruptcy, has caused difficulties in tracing and identifying radioactive sources and materials and a deterioration of the system of safety, physical protection, etc. of radioactive material. In some cases, radioactive sources were stolen because of the value of their protective containers and sold for scrap metal. This led to the occurrence of different types of radiation incidents, mainly related to the discovery of radioactive sources in scrap metal. The consequences of these incidents include the risk of radiation exposure of the workers at scrap metal yards or reprocessing facilities and of members of the public and, in addition, radioactive contamination of the environment. The Bulgarian Nuclear Regulatory Agency (BNRA) has been responding to these incidents and has carried out a series of measures to improve the control over materials (e.g. activated or surface contaminated materials) and radioactive sources and to strengthen the preventive, monitoring, emergency preparedness and mitigating measures at facility, national and transboundary levels. This paper presents an analysis of the lessons learned by the BNRA and of the control of the transboundary movement of radioactively contaminated scrap metal through the territory of Bulgaria.

    2017-09-01

    The purpose of this report is to review and compile what have been and can be learnt from incidents and accidents in radiation oncology, especially in external beam and brachytherapy. Some major accidents from the last 20 years will be discussed. The relationship between major events and minor or so-called near misses is mentioned, leading to the next topic of exploring the knowledge hidden among them. The main lessons learnt from the discussion here and elsewhere are that a well-functioning and safe radiotherapy department should help staff to work with awareness and alertness and that documentation and procedures should be in place and known by everyone. It also requires that trained and educated staff with the required competences are in place and, finally, functions and responsibilities are defined and well known.

    Energy Technology Data Exchange (ETDEWEB)

    Lum, J. [Dept. of Energy, Washington, DC (United States)

    1993-03-01

    The purpose of this presentation is to relay the experience of the Office of New Production Reactors (NP) in developing and implementing its pollution prevention program. NP was established to plan, design, and construct a new safe and environmentally acceptable nuclear reactor capacity necessary to provide an assured supply of tritium to maintain the nation`s long-term deterrent capability. The Program offered the Department of Energy an opportunity to demonstrate its commitment to environmental protection via minimization of environmental releases; new design offers the best opportunity for pollution prevention. The NP pollution prevention program was never fully implemented because NP`s tritium production design activity was recovery terminated. The information in this paper represented lessons learned from the last three years of NP operation.

    In recent years, community-based coalitions have become an effective channel to addressing various health problems within specific ethnic communities. The purpose of this article is twofold: (a) to describe the process involved in building the Kalusugan Coalition (KC), a Filipino American health coalition based in New York City, and (b) to highlight the lessons learned and the challenges from this collaborative venture. The challenges described also offer insights on how the coalition development process can be greatly affected by the partnership with an academic institution on a community-based research project. Because each cultural group has unique issues and concerns, the theoretical framework used by KC offers creative alternatives to address some of the challenges regarding coalition infrastructures, leadership development, unexpected change of coalition dynamics, and cultural nuances.

    2015-07-01

    Full Text Available Background: The unprecedented global growth in older adults merits high-quality gerontological nursing care. As gerontological nursing grows in visibility in developed and developing countries, nurses must possess a broader worldview of ageing with knowledge of physiological, psychosocial, and cultural issues. Purpose: The purpose of this article is to: (1 highlight lessons learned on differences and similarities in ageing and care of older adults in the United States of America (USA and South Africa (SA; and (2 provide recommendations on how to advance gerontological nursingeducation in SA. Methods: A two-week international service-learning project was undertaken by visiting SA and learning about their nursing system and care of older adults. Service-learning is an innovative teaching-learning-service method that provided reflective and hands-on experience of gerontological nursing. This article provides a personal reflection of lessons learned about ageing and gerontological nursing during the service-learning project. Findings: Care of older adults in SA is in many ways different from and similar to that in the USA. Consequently global nurses should recognise those differences and provide culturally appropriate care. This service-learning experience also demonstrated the need for gerontological nursing education in SA. Based on this, recommendations on how to infuse and advance gerontological nursing education in SA are provided. Conclusion: Caring for older adults in a global context requires knowledge and understanding of cultures and their values and practices. With a growing population of diverse older adults, there is a need for incorporation

    2016-09-19

    Purpose The purpose of this paper is to present lessons learnt through the development of an evaluation framework for a clinical redesign programme - the aim of which was to improve the patient journey through improved discharge practices within an Australian public hospital. Design/methodology/approach The development of the evaluation framework involved three stages - namely, the analysis of secondary data relating to the discharge planning pathway; the analysis of primary data including field-notes and interview transcripts on hospital processes; and the triangulation of these data sets to devise the framework. The evaluation framework ensured that resource use, process management, patient satisfaction, and staff well-being and productivity were each connected with measures, targets, and the aim of clinical redesign programme. Findings The application of business process management and a balanced scorecard enabled a different way of framing the evaluation, ensuring measurable outcomes were connected to inputs and outputs. Lessons learnt include: first, the importance of mixed-methods research to devise the framework and evaluate the redesigned processes; second, the need for appropriate tools and resources to adequately capture change across the different domains of the redesign programme; and third, the value of developing and applying an evaluative framework progressively. Research limitations/implications The evaluation framework is limited by its retrospective application to a clinical process redesign programme. Originality/value This research supports benchmarking with national and international practices in relation to best practice healthcare redesign processes. Additionally, it provides a theoretical contribution on evaluating health services improvement and redesign initiatives.

    2015-07-01

    Full Text Available This paper offers a framework for mathematics lesson design that is consistent with the way we learn about, and discover, most things in life. In addition, the framework provides a structure for identifying how mathematical concepts and understanding are acquired and developed. This framework is called ELPSA and represents five learning components, namely: Experience, Language, Pictorial, Symbolic and Applications. This framework has been used in developing lessons and teacher professional programs in Indonesia since 2012 in cooperation with the World Bank. This paper describes the theory that underlines the framework in general and in relation to each inter-connected component. Two explicit learning sequences for classroom practice are described, associated with Pythagoras theorem and probability. This paper then concludes with recommendations for using ELPSA in various institutional contexts.Keywords: ELPSA, lesson design framework, Pythagoras theorem, probability DOI: dx.doi.org/10.22342/jme.62.77

    Full Text Available In the process of transition of Russian organizations of secondary professional education to educational standards of the third generation educational process is reduced to formation of students’ competences. This article presents methodology of creating integrated lessons of natural-science cycle (for example, in physics and informatics. These lessons are constructed on the basis of interdisciplinary integration and focused on task solution. The main purpose is to teach students how to solve particular tasks in physics with the use of informatics, in particular on the basis of algorithmization and programming (Pascal language. Didactic conditions, which are the basis of the algorithm of designing corresponding tasks, are described in this article. Structural components of the integrated lessons created on the traditional principle are marked out. During the research we observed that realization of all stages of the corresponding lessons in practice allows the teacher to create educational process over the borders of disciplinary basis. This approach helps to form generalization of knowledge. Being one of the most optimal forms of education, an integrated lesson allows students to solve various educational and professional problems in non-standard situations and stimulates their cognitive activity and their involvement in the process of education and their responsibility for the result which promotes an intensification of educational process.

    Supernovae and Gamma-Ray bursts display many similarities, both in their observational qualities and in the engines behind these powerful explosions. Although not identical, there is a strong synergy in the study of these two objects. There is much the gamma-ray burst field can learn from the lessons of the more-developed supernova field, but the supernova field can also learn from new techniques developed for gamma-ray burst studies. Here I review some of the 'lessons learned' from these fields to help foster this synergy.

    2011-01-01

    SAIC's development of VACIS provides useful 'lessons learned' in bridging the gap from an idea to a security or contraband detection product. From a gamma densitometer idea for solving a specific Customs Service (CS) requirement (detection of drugs in near-empty tanker trucks) in mid-1990's, SAIC developed a broad line of vehicle and cargo inspections systems (over 500 systems deployed to date) based on a gamma-ray radiographic imaging technique. This paper analyzes the reasons for the successful development of VACIS and attempts to identify ''lessons learned'' useful for future security and contraband detection product developments.

    Forty years of human spaceflight activities are now culminating in the International Space Station program (ISS). The ISS involves fifteen nations, working together to create a permanently occupied orbital facility that will support scientific and potentially, commercial endeavours. The assembly of the ISS is scheduled to be completed later in this decade, after which it will be operated for at least ten years. At the strategic level, such a complex international project is highly dependent on the fifteen Partners' respective internal politics and foreign policies. On the operational level, Partners still have certain difficulties in issuing and agreeing to common technical procedures. As with almost all aspects of International Space Station cooperation, the Partners are going through a constant learning process, where they have to deal with complex political, legal and operational differences. Intergovernmental Agreement and the Memoranda of Understanding, the instruments forming the legal backbone of the International Space Station cooperation, are still lacking a fair number of arrangements that need to be created for completing and operating the Station. The whole endeavour is also a constant learning process at the operational level, as astronauts, cosmonauts, engineers and technicians on the ground with different cultural and educational backgrounds, learn to work together. One recent Space Shuttle mission to the Station showed the importance of standardising even trivial system components such as packaging labels, as it took the astronauts half a day more than planned to correctly unpack the equipment. This paper will provide a synthesis of some of the main lessons learned during the first few years of International Space Station's lifetime. Important political, legal and operational issues will be addressed and combined. This analysis will provide some guidelines and recommendations for future international space projects, such as an international human

    It has been almost 12 months since the Fukushima nuclear disaster began. Although the Great East Japan earthquake and the following tsunami triggered it, the key causes of the nuclear accident lie in the institutional failures of political influence and industry-led regulation. It was a failure of human institutions to acknowledge real reactor risks, a failure to establish and enforce appropriate nuclear safety standards and a failure to ultimately protect the public and the environment. This report, commissioned by Greenpeace International, addresses what lessons can be taken away from this catastrophe. The one-year memorial of the Fukushima accident offers a unique opportunity to ask ourselves what the tragedy - which is far from being over for hundreds of thousands of Japanese people - has taught us. And it also raises the question, are we prepared to learn? There are broader issues and essential questions that still deserve our attention: - How it is possible that - despite all assurances - a major nuclear accident on the scale of the Chernobyl disaster of 1986 happened again, in one of the world's most industrially advanced countries? - Why did emergency and evacuation plans not work to protect people from excessive exposure to the radioactive fallout and resulting contamination? Why is the government still failing to better protect its citizens from radiation one year later? - Why are the over 100,000 people who suffer the most from the impacts of the nuclear accident still not receiving adequate financial and social support to help them rebuild their homes, lives and communities? These are the fundamental questions that we need to ask to be able to learn from the Fukushima nuclear disaster. This report looks into them and draws some important conclusions: 1. The Fukushima nuclear accident marks the end of the 'nuclear safety' paradigm. 2. The Fukushima nuclear accident exposes the deep and systemic failure of the very institutions that are supposed to

    Illness blogs are a way seriously ill people communicate publicly about their illness journey. As communication about serious illness increases on social media, it is important to evaluate how this affects the family caregiver. However, identifying and accessing family caregivers remains challenging, especially via social media. The aim of this article is to report the opportunities, challenges and lessons learned from using social media to recruit family caregivers. Recruitment methods included posting study invitations on illness blogs, advertising through Facebook and placing study fliers in the community. Using social media to recruit was inexpensive and provided a wide geographical reach. One important finding was discovering the importance of using language in the recruitment materials that family caregivers could identify with to help deem themselves as eligible to participate in the study.

    McDowell, Amy Virginia

    The purpose of this study was to explore preservice teachers' lived experiences in a lesson study focused on teaching and learning nature of science (NOS). The body of knowledge about shifting pre- and in-service novice NOS understandings is substantial. The focus of science education research is now exploring ways to move these informed NOS understandings into classroom practice (Abd-El-Khalick & Lederman, 2000b). The research questions guiding the study were (a) how do preservice teachers' understandings of NOS shift as a result of the lesson study experience?, and (b) how does the reflective practice that occurs in lesson study influence preservice teachers' transition of NOS tenets into classroom practice? The participants in this study represented a sample of graduate preservice teachers, who were part of a middle and secondary science teaching alternative certification program in a southeastern university. In the first summer semester of this certification program, the participants were immersed in reform based science instruction; a section of which included NOS teachings (INTASC, 2002). In the following semester, participants were placed in a practicum setting; where the exploration of the preservice teachers' teaching of NOS was supported through the modified lesson study framework. Data sources included the Views on Nature of Science-Form B (VNOS-b), interviews, and lesson study portfolios. Analysis of NOS understandings was guided by instruments found in literature associated with the VNOS-b (Lederman et al., 2002) and reflection (Ward & McCotter, 2004). Results showed successful transfer of NOS into classroom practice using the modified lesson study framework, with less success in the deepening of participants' NOS understandings. Of particular significance was that results indicated a deepening of NOS pedagogical content knowledge for those participants functioning at higher levels of reflection. The study's results contributes to two knowledge bases

    The contribution includes the lessons learned within frame of the radiological characterisation of surface ground layer in the NPP A1 site of area approximately 60 m2 (9 x 7 m) that was a part of Controlled area. Aim of the characterisation was a demonstration that the area fulfils the requirements to exemption from Controlled area for purpose of decommissioning activities carry out within frame of II. stage of NPP A1 decommissioning project.The requirements on free release of materials into the environment were applied (e.g. 300 Bq/kg for single 137 Cs). Radiological characterisation was performed by two independent methods; in situ scintillation gamma spectrometry and systematic sampling in regular grid followed by gamma spectrometry analyses in accredited laboratory of VUJE, Inc. (S-219). This improved the quality of monitoring and at the same time it enabled the inter-comparison of results obtained by both mentioned independent methods.Characterised ground area was partitioned to smaller sub-areas of 4 m2. At ground layer of 20 cm it means approximately 1000 kg of ground (in compliance with requirements on reference area at even activity distribution according to government regulation No 345/2006) The results of measurements showed that under appropriate conditions (sufficiently low radiation background, on interfering external sources) also the designed in situ method is effective and reliable tool for contaminated ground layer identification. In addition the in situ method is more effective in terms of time and cost consumption on unit of monitored area. (authors)

  17. Lessons learned from the Galileo and Ulysses flight safety review experience

    Bennett, Gary L.

    1998-01-01

    In preparation for the launches of the Galileo and Ulysses spacecraft, a very comprehensive aerospace nuclear safety program and flight safety review were conducted. A review of this work has highlighted a number of important lessons which should be considered in the safety analysis and review of future space nuclear systems. These lessons have been grouped into six general categories: (1) establishment of the purpose, objectives and scope of the safety process; (2) establishment of charters defining the roles of the various participants; (3) provision of adequate resources; (4) provision of timely peer-reviewed information to support the safety program; (5) establishment of general ground rules for the safety review; and (6) agreement on the kinds of information to be provided from the safety review process

  18. Previous experience in manned space flight: A survey of human factors lessons learned

    1993-01-01

    Previous experience in manned space flight programs can be used to compile a data base of human factors lessons learned for the purpose of developing aids in the future design of inhabited spacecraft. The objectives are to gather information available from relevant sources, to develop a taxonomy of human factors data, and to produce a data base that can be used in the future for those people involved in the design of manned spacecraft operations. A study is currently underway at the Johnson Space Center with the objective of compiling, classifying, and summarizing relevant human factors data bearing on the lessons learned from previous manned space flights. The research reported defines sources of data, methods for collection, and proposes a classification for human factors data that may be a model for other human factors disciplines.
