    As part of the engineering effort for the Advanced Light Water Reactor the Advanced Reactor Corporation formed a Piping Technical Core Group to develop a set of improved ASME Boiler and Pressure Vessel Code, Section III design rules and approaches for ALWR plant piping and support design. The technical basis for the proposed changes to the ASME Boiler and Pressure Vessel Code developed by Technical Core Group for the design of piping relies heavily on the failure margins determined from the EPRI/USNRC piping component test program. The majority of the component tests forming the basis for the reported margins against failure were run with input frequency to natural frequency ratios (Ω/ω) in the range of 0.74 to 0.87. One concern investigated by the Technical Core Group was the effect which could exist on measured margins if the tests had been run at higher or lower frequency ratios than those in the limited frequency ratio range tested. Specifically, the concern investigated was that the proposed Technical Core Group Piping Stress Criteria will allow piping to be designed in the low frequency range (Ω/ω ≥ 2.0) for which there is little test data from the EPRI/USNRC test program. The purpose of this analytical study was to: (1) evaluate the potential for margin variation as a function of the frequency ratio (R ω = Ω/ω, where Ω is the forcing frequency and ω is the natural component frequency), (2) recommend a margin reduction factor (MRF) that could be applied to margins determined from the EPRI/USNRC test program to adjust those margins for potential margin variation with frequency ratio. Presented in this paper is the analytical approach and methodology, which are inelastic analysis, which was the basis of the study. Also, discussed is the development of the analytical model, the procedure used to benchmark the model to actual test results, and the various parameter studies conducted

    As satellite communications systems become both more complex and reliant with respect to their operating environment, it has become imperative to be able to identify, during real-time operation, the onset of one or more impairments to the quality of overall communications system integrity. One of the most important aspects to monitor of a satellite link operating within the Earth's atmosphere is the signal fading due to the occurrence of rain and/or phase scintillations. This, of course, must be done in the presence of the associated measurement uncertainty or potentially faulty measurement equipment such as in the Advanced Communication Technology Satellite (ACTS) experiment. In the present work, an approach originally suggested in 1991, and apparently still considered iconoclastic, will be significantly developed and applied to the satellite communications link on which the deleterious composite signal fade is the result of one or many component fade mechanisms. Through the measurement (with the attendant uncertainty or 'error' in the measurement) of such a composite fading satellite signal, it is desired to extract the level of each of the individual fading mechanisms so they can be appropriately mitigated before they impact the overall performance of the communications network. Rather than employing simple-minded deterministic filtering to the real-time fading, the present approach is built around all the models and/or descriptions used to describe the individual fade components, including their dynamic evolution. The latter is usually given by a first-order Langevin equation. This circumstance allows the description of the associated temporal transition probability densities of each of the component processes. By using this description, along with the real-time measurements of the composite fade (along with the measurement errors), one can obtain statistical estimates of the levels of each of the component fading mechanisms as well as their predicted values

    The constitutive equations to model the hot flow behaviour of metallic materials in general, and of microalloyed steels in particular (see part 2 of this work) are established in this work. Special emphasis is done on the dynamic softening mechanisms, i.e., dynamic recovery and recrystallization phenomena. The equations developed are physic-based, not empirical, and the modelling allows an easy implementation in an analysis by numerical methods. The resulting equations are even able to predict the final grain size. (Author) 39 refs

    1997-01-01

    The hot working processes constitute an important step in the manufacture of components for engineering applications. In the past, the mechanical processing have been used to impart a shape to the engineering materials. More recently, however, the hot working processes are used not only to achieve the required shape but also to impart desirable mechanical and microstructural characteristics by an adequate design of the thermomechanical process. The aim of the present paper is to summarize the general characteristics of the Dynamic Materials Model. In this model, the work piece material under hot working conditions is considered to be a dissipator of power. Also, the extreme principles of irreversible thermodynamics applied to large plastic flow are described to develop a continuum criterion capable to predict the metallurgical instabilities in a hot worked material.

    The theoretical background for the finite element computer program, MPSalsa, is presented in detail. MPSalsa is designed to solve laminar, low Mach number, two- or three-dimensional incompressible and variable density reacting fluid flows on massively parallel computers, using a Petrov-Galerkin finite element formulation. The code has the capability to solve coupled fluid flow, heat transport, multicomponent species transport, and finite-rate chemical reactions, and to solver coupled multiple Poisson or advection-diffusion- reaction equations. The program employs the CHEMKIN library to provide a rigorous treatment of multicomponent ideal gas kinetics and transport. Chemical reactions occurring in the gas phase and on surfaces are treated by calls to CHEMKIN and SURFACE CHEMKIN, respectively. The code employs unstructured meshes, using the EXODUS II finite element data base suite of programs for its input and output files. MPSalsa solves both transient and steady flows by using fully implicit time integration, an inexact Newton method and iterative solvers based on preconditioned Krylov methods as implemented in the Aztec solver library.

    The measurement of the prompt γ following neutron capture in the reaction has been extensively developed. In this method the gamma-ray intensity is depended only upon the radiative capture cross-section and not upon the half-life of the product nucleus. The prompt gamma-ray activation analysis method stems from the radiative capture process which results in the decay of the compound nucleus by the emission of characteristic gamma radiation, either as a single photon with kinetic energy equal to the excitation energy less the recoil energy or, more likely, by a cascade of two or more photons with the same energy. The equations and the computer program required to calculate the yield, the intensity and the K χ emission probability per disintegration, are given in this study.(author)

    New manufacturing methods have applied for automotive parts to reduce total weight of car, resulting in improvement of fuel efficiency. TWB technique is applied to auto body parts, especially door inner, side inner and outer panel, and center floor panel to accomplish this goal. We applied non-linear (circular welded) TWB to shock absorber housing (to reduce total weight of shock absorber housing assembly). Welding line and shape of blank were determined by FEM analysis. High formability steel sheet and 440MPa grade high strength steel sheet were laser welded and press formed to final shock absorber housing (S/ABS HSG) panel and assembled with other sub parts. As a result, more than 10% of total weight of shock absorber housing assembly could be reduced compared with the mass of same part manufactured by conventional method. Also circular welding technique made it possible to design optimum welding line of TWB part. This paper is about result of FEM analysis and development procedure of non-linear TWB part (shock absorber housing assembly). (orig.)

    Clinical preception in practice plays a significant role in both registered and practical nurse studies. As such, the cooperation between the faculty and working life is important to narrow the theory-practice gap, with emphasis being placed on a student-oriented approach promoting self-direction and lifelong learning. The aim of this project was to develop the preceptorship at five different units within the health-care sector in western Finland by implementing an action research (AR) approach. This article is the first of a two-part article on the project, focusing on a cultural analysis and the development of preception models conducted within the project. The five units participating in the study were the following: a long-term care ward in the community, a ward for people with dementia, a geriatric ward, a medical ward and a surgical ward representing specialised care. The starting point of the study was a cultural analysis, which was made in all the five units to obtain a 'bottom-up' perspective. In each of the five units 3-5 nurses were appointed to become members of the core groups. This meant that all the units would start from the perspective of their own working environment when creating a preception model that would fit into their particular workplace. During this process, the participants received continuous support from the researchers. Several workshops and seminars were also arranged to further support the core groups and staff. The models were implemented and tested during the academic year 2010-2011 followed by an evaluation of the project. The evaluation results will be presented in the second part of the two-part article. The project showed that reflective practice and critical thinking can be improved through an AR approach. © 2015 Nordic College of Caring Science.

    Full Text Available Purpose. The paper focuses on ensuring the rational choice of parameters of the mating surfaces of parts when designing process equipment based on the methods of artificial intelligence. Methodology. The paper considers the geometric model of a ruled developed surface, the conditions of existence of such a surface and provides a generalized algorithm for surface plotting regardless of the type of the working element or the machine-building product. One of the most common technical surfaces are the ruled ones, among which a special position is occupied by developed surfaces (thanks to their differential-parametric properties: surface tangent plane is n contact along the rectilinear generator and does not change its position in space when changing the point of contact; surfaces can be produced by bending sheet metal. These provisions enable a product manufacturer to save significant material and energy means, therefore, the development of geometric models of such surfaces is an important task. Findings. We analyzed the geometrical model of the developed surface which is incident to two guides. Experimental studies have shown the applicationprospectivity of semi-digger moldboards on moldboard plows, particularly on the double-deck ones. Taking into account the operating speed of the plow 2.8 m/s, the plant residues plowing percentage for plow with semi-digger moldboards is 98.9%, and with the digger ones – 96.1%. Originality. According to results: 1 the approaches to solving the problem of recognition of wear conditions of the tested interface, depicted by its conceptual model, were elaborated; 2 the corresponding algorithms of the computational procedures were built; 3 the mathematical model that determines the effect of the parameters of the contacting surfaces on their performance properties – linear wear rate during the normal wear and tear was developed; 4 for this model the theoretical prerequisite of use for the random mating study were

    The nineteen eighties has been a time in which Cosmology and Particle Physics have come together. This dissertation reflects that trend. It does so in two ways. First, in Chapters 1 through 3, there is a theoretical investigation into some aspects of generational universality. The consequences of a third lepton, namely the tauon, and an associated tau neutrino, are explored in terms of phenomenology (mass and V-A consistency) that may shed insight into questions of neutrino mass and increased symmetry at higher energies. Second, in Chapters 4 through 11, there is an experimental investigation in the form of constructing and operating the first stage of the DUMAND (Deep Underwater Muon and Neutrino Detection) project which was a ship suspended muon and neutrino telescope called the SPS (Short Prototype String). This detector is of the water Cherenkov type and is the first time such an instrument has been successfully built and tested for use in the ocean. Chapters 6 through 10 are devoted to the detailed documentation of the parts of the SPS and its technology integration that I designed, prototyped, and debugged. In particular, a complete description is given to the command and control communications system of the string, the digital control electronics and associated software for the Optical, Calibration, and Power modules as well as the fast digitizing electronics or String Bottom Controller (SBC). This includes the development of a microcontroller language UHPS (Underwater Hawai'i Programming System). Finally, Chapter 11 is an analysis of SPS data in terms of ascertaining a purely statistically based downward traveling muon rate at a depth of 4.0 Km yielding (2.06 ± 0.68) x 10 -2 Hz

    Cognitive science has become the most influential paradigm on mental health in the late 20(th) and the early 21(st) centuries. In few years, the concepts, problem approaches and solutions proper to this science have significantly changed. Introduction and discussion of the fundamental concepts of cognitive science divided in four stages: Start, Classic Cognitivism, Connectionism, and Embodying / Enacting. The 2(nd) Part of the paper discusses the above mentioned fourth stage and explores the clinical setting, especially in terms of cognitive psychotherapy. The embodying/enacting stage highlights the role of the body including a set of determined evolutionary movements which provide a way of thinking and exploring the world. The performance of cognitive tasks is considered as a process that uses environmental resources that enhances mental skills and deploys them beyond the domestic sphere of the brain. On the other hand, body and mind are embedded in the world, thus giving rise to cognition when interacting, a process known as enacting. There is a close connection between perception and action, hence the interest in real-time interactions with the world rather than abstract reasoning. Regarding clinics, specifically the cognitive therapy, there is little conceptual discussion maybe due to good results from practice that may led us to consider that theoretical foundations are firm and not problem-raising.

    The multibarrier concept produces a composite waste form with enhanced inertness through improvements in thermal stability, mechanical strength, and leachability by the use of coatings and metal matrices. This report describes research and development activities resulting in the demonstration of the multibarrier concept for nonradioactive simulated waste compositions. The multibarrier concept is to utilize up to three barriers to isolate radionuclides from the environment: a solid waste inner core, an impervious coating, and a metal matrix. Two inner core materials, sintered supercalcine and glass marbles, have been demonstrated. The coating barrier provides enhanced leach, impact, and oxidation resistance as well as thermal protection during encapsulation in the metal matrix. Py/Al 2 O 3 coatings deposited by chemical vapor deposition (CVD) and glass coatings have been applied to supercalcine cores to improve inertness. The purpose of the metal matrix is to improve impact resistance, protect the inner core rom any adverse environments, provide radiation shielding, and increase thermal conductivity, yielding lower internal temperatures. The development of gravity sintering and vacuum casting techniques for matrix encapsulation are discussed. Four multibarrier products were demonstrated: (1) Glass marbles encapsulated in vacuum-cast Pb-10Sn; (2) uncoated, sintered supercalcine pellets encapsulated in vacuum-cast Al-12Si; (3) glass-coated, sintered supercalcine pellets encapsulated in vacuum-cast Al-12Si; and (4) PyC/Al 2 O 3 -coated supercalcine encapsulated in gravity-sintered Cu. 23 figs., 20 tables

    The use of air/water heat pumps for heating of houses is progressively increasing. It is to be expected that the average coefficient of performance (COP) can be improved substantially over the next decade. Its success will depend on controlling and reducing the formation of frost and ice which reduce the air flow and the heat and mass transfer in the fin tube evaporator. In the LOREF research project a mathematical-physical simulation program has been developed which permits to calculate the formation of condensate, ice and frost and also the pressure loss of the air as a function of space and time at any condition of the ambient air. The theoretical results have been validated by numerous experiments in which the air temperature and humidity, the temperature difference and the air velocity have been systematically varied. Particular emphasis has been given to the geometries of the fin tube evaporator. Several fin partitions along the cooler have been investigated. Using the simulation program the evaporator of a commercial heat pump was optimized and experimentally compared to the original evaporator. The resulting seasonal performance factors were nearly equal what confirms the small differences obtained by simulations. Nevertheless, the optimized evaporator features advantages in respect of the defrosting with ambient air because of its bigger fin spacing and the resulting decrease in pressure drop. The results of the LOREF research project are now the basis for the overall optimization of air/water heat pumps. (author)

    Cohen, S. C.

    1979-01-01

    A model of viscoelastic deformations associated with earthquakes is presented. A strike-slip fault is represented by a rectangular dislocation in a viscoelastic layer (lithosphere) lying over a viscoelastic half-space (asthenosphere). Deformations occur on three time scales. The initial response is governed by the instantaneous elastic properties of the earth. A slower response is associated with viscoelastic relaxation of the lithosphere and a yet slower response is due to viscoelastic relaxation of the asthenosphere. The major conceptual contribution is the inclusion of lithospheric viscoelastic properties into a dislocation model of earthquake related deformations and stresses. Numerical calculations using typical fault parameters reveal that the postseismic displacements and strains are small compared to the coseismic ones near the fault, but become significant further away. Moreover, the directional sense of the deformations attributable to the elastic response, the lithospheric viscoelastic softening, and the asthenospheric viscoelastic flow may differ and depend on location and model details. The results and theoretical arguments suggest that the stress changes accompanying lithospheric relaxation may also be in a different sense than and be larger than the strain changes.

    The Waste Isolation Pilot Plant (WIPP) in southeast New Mexico has been studied as a transuranic waste repository for the past 23 years. During this time, an extensive site characterization, design, construction, and experimental program was completed, which provided in-depth understanding of the dominant processes that are most likely to influence the containment of radionuclides for 10,000 years. Nearly 1,500 parameters were developed using information gathered from this program; the parameters were input to numerical models for WIPP Compliance Certification Application (CCA) Performance Assessment (PA) calculations. The CCA probabilistic codes frequently require input values that define a statistical distribution for each parameter. Developing parameter distributions begins with the assignment of an appropriate distribution type, which is dependent on the type, magnitude, and volume of data or information available. The development of the parameter distribution values may require interpretation or statistical analysis of raw data, combining raw data with literature values, scaling of lab or field data to fit code grid mesh sizes, or other transformation. Parameter development and documentation of the development process were very complicated, especially for those parameters based on empirical data; they required the integration of information from Sandia National Laboratories (SNL) code sponsors, parameter task leaders (PTLs), performance assessment analysts (PAAs), and experimental principal investigators (PIs). This paper, Part 1 of two parts, contains a discussion of the parameter development process, roles and responsibilities, and lessons learned. Part 2 will discuss parameter documentation, traceability and retrievability, and lessons learned from related audits and reviews

    LPMS (loose parts monitoring system) is one of the most important structural integrity monitoring systems. It is operated for a early detection of the impacts by loosened or detached metallic, objects on the primary pressure boundary in a nuclear power plant. The impacted parts might cause flow blockage in the fuel channel, prevent the control rod from moving properly, damage the pump impeller, and give rise to cracks on the steam generator tube sheet, etc. In Korea, The LPMS is currently operating in all of the nuclear power plants as a subsystem in the NIMS (NSSS Integrity Monitoring System), However the performances are being deteriorated in both the hardware and software since it was designed in 1980's. In particular the system is not capable of promptly responding to the continuously triggered impacts in a short period failing to monitor the real loose parts. Also the diagnostic tools to estimate the location and the mass or energy of the impact source have not been reflected. Therefore, a new loose parts monitoring system has been developed to improve the capabilities of the current one and ultimately to replace it. An enhanced Loose Parts Monitoring System(LPMS) has been developed by KAERI(Korea Atomic Energy Research Inst.), not only to improve the performance of an on-line signal processing for a monitoring system but also to enhance the evaluation technique of the true impact signals by loose parts. This new system has taken into account the state-of-the-art technology to cover the problems with the conventional system. (authors)

    Part I of this thesis concerns characterization of catalyst materials prepared by an ion beam implanter and by a multiple expansion cluster source. Ion beam synthesis was carried out on a 250-kev ion implanter. After assembling a special reaction chamber, zeolites were implanted with phosphorous and iron. This work contributed to development of a sputter reactor for ion beam synthesis. Silver catalysts were examined in a reactor designed, built and evaluated for catalysts produced by the sputter reactor and by a multiple expansion cluster source. Small surface area silver foil catalysts and silver cluster catalysts showed kinetic activity for epoxidation of ethylene. Positive results for the small surface area silver cluster catalyst demonstrate the feasibility of studying these catalysts with the special reactor. Part 2 concerns fundamentals and applications of secondary ion mass spectrometry. A data system was implemented for a secondary ion mass spectrometer that involved design and construction of a computer interface. Software routines for the interface were written in assembly language for increased operation efficiency

    Cycloalkanes are significant constituents of conventional fossil fuels, in which they are one of the main contributors to soot formation, but also significantly influence the ignition characteristics below ∼900K. This paper discusses the development of a detailed high- and low-temperature oxidation mechanism for cyclopentane, which is an important archetypical cycloalkane. The differences between cyclic and non-cyclic alkane chemistry, and thus the inapplicability of acyclic alkane analogies, required the detailed theoretical investigation of the kinetics of important cyclopentane oxidation reactions as part of the mechanism development. The cyclopentyl+O reaction was investigated at the UCCSD(T)-F12a/cc-pVTZ-F12//M06-2X/6-311++G(d,p) level of theory in a time-dependent master equation framework. Comparisons with analogous cyclohexane or non-cyclic alkane reactions are presented. Our study suggests that beyond accurate quantum chemistry the inclusion of pressure dependence and especially that of formally direct kinetics is crucial even at pressures relevant for practical application.

    Full Text Available The here presented Performance method of drama workshops was developed on basis of professional staging (actress, singer, working with people (mentor, trainer, permanent learning, research and analyses of the use of voice and body language on the exposed stage in interpersonal communication and exploration of positive effects of an individual being part of such a creative process. It has been tested working with people of diverse backgrounds and mixed interest groups. The experience and knowledge acquired from drama workshops serve an individual as an aid of overcoming obstacles, developing survival strategies, better understanding and accepting of oneself and surroundings and designing the desired interaction patterns. This enables the participants to take over the responsibility to improve their quality of life. On the area of education (where motivation and interaction are crucial elements of knowledge transmission  as well as working with vulnerable groups, we have come to a conclusion that the way these workshops work helps participants recognizing their own and unfamiliar behavior patterns – seeing themselves and other from a different perspective, neutralizing tension in interpersonal and professional relationships. Participants experience own expressive and creative potential. Believing in their own possibilities and creativity, it increases faith in life, which offers the feeling of personal fulfillment. Findings have been collected on basis of evaluations, questionnaires, discussions, in-depth discussions, diary entries, work in groups and video footages (with permission of the participants.

    2001-01-01

    Of the total consumption of electricity in Slovakia, 42% was generated in nuclear power plant units in 1999. Slovakia operates 6 units with a WWER 440 nuclear reactors, 4 of them are at Bohunice site and 2 at Mochovce. The Nuclear Regulatory Authority of SR is not the only regulatory body controlling nuclear activity. Both - the system of nuclear activities regulation in Slovakia as well as the approach to Nuclear Safety enhancement of the operator were positively judged by IAEA and WENRA. In 1993 -Slovakia has accepted the commitments of the UN Convention on Climate Changes, including a reduction of greenhouse gases to 1990 levels by the year 2000. Moreover, as an internal target Slovakia has set the reaching of the ,'Toronto Objective', i.e. 20% reduction in CO x emissions through the year 2005 as compared to 1988. Taking into account the actual situation as well as natural conditions for some renewable sources utilisation, the target won't be reached without nuclear energy. The nuclear energy is free of emissions, does not burn oxygen, and with the share of production in Slovakia will remain significant contributor. To the environment protection it contributes also by replacing fossil heat plants with heat delivery for the region. In case of radiological wastes the environment protection is ensured by very strict system of control, evidence, treatment and repository. To conclude, Bohunice NPPs were, are and will remain very important part of the Slovak's economy, creating conditions for its (sustainable) development

    Tramel, Terri L.; Welker, Roger; Lowery, Niki; Mitchell, Mark

    2014-01-01

    Additive Manufacturing of metallic components for aerospace applications offers many advantages over traditional manufacturing techniques. As a new technology, many aspects of its widespread utilization remain open to investigation. Among these are the cleaning processes that can be used for post finishing of parts and measurements to verify effectiveness of the cleaning processes. Many cleaning and drying processes and measurement methods that have been used for parts manufactured using conventional techniques are candidates that may be considered for cleaning and verification of additively manufactured parts. Among these are vapor degreasing, ultrasonic immersion and spray cleaning, followed by hot air drying, vacuum baking and solvent displacement drying. Differences in porosity, density, and surface finish of additively manufactured versus conventionally manufactured parts may introduce new considerations in the selection of cleaning and drying processes or the method used to verify their effectiveness. This presentation will review the relative strengths and weaknesses of different candidate cleaning and drying processes as they may apply to additively manufactured metal parts for aerospace applications. An ultrasonic cleaning technique for exploring the cleanability of parts will be presented along with an example using additively manufactured Inconel 718 test specimens to illustrate its use. The data analysis shows that this ultrasonic cleaning approach results in a well-behaved ultrasonic cleaning/extraction behavior. That is, it does not show signs of accelerated cavitation erosion of the base material, which was later confirmed by neutron imaging. In addition, the analysis indicated that complete cleaning would be achieved by ultrasonic immersion cleaning at approximately 5 minutes, which was verified by subsequent cleaning of additional parts.

    Laval, H.

    1981-01-01

    This report describes the theoretical and numerical aspects of the finite element computer code CONVEC designed for the transient analysis of two-dimensional plane or three-dimensional axisymmetric incompressible flows including the effects of heat transfer. The governing equations for the above class of problems are the time-dependent incompressible Navier-Stokes equations and the thermal energy equation. The general class of flow problems analysed by CONVEC is discussed and the equations for the initial-boundary value problem are represented. A brief description of the finite element method and the weighted residual formulation is presented. The numerical solution of the incompressible equations is achieved by using a fractional step method. The mass lumping process associated with an explicit time integration scheme is described. The time integration is analysed and the stability conditions are derived. Numerical applications are presented. Standard problems of natural and forced convection are solved and the solutions obtained are compared with other numerical solutions published in the literature

  3. The training process: Planning for strength–power training in track and field. Part 1: Theoretical aspects

    2015-12-01

    Full Text Available The process of strength–power training and the subsequent adaptation is a multi-factorial process. These factors range from the genetics and morphological characteristics of the athlete to how a coach selects, orders, and doses exercises and loading patterns. Consequently, adaptation from these training factors may largely relate to the mode of delivery, in other words, programming tactics. There is strong evidence that the manner and phases in which training is presented to the athlete can make a profound difference in performance outcome. This discussion deals primarily with block periodization concepts and associated methods of programming for strength–power training within track and field.

    The thalidomide disaster was the significant historical event that acted as a catalyst for pharmacovigilance activity. Following this event developed countries initiated drug monitoring systems that evolved and now extend their scope to broader drug-related safety issues; however, this was not the case in developing countries. Pharmacovigilance is still a relatively new concept with low priority in developing countries although various issues are raising concerns that magnify the need for systems to monitor post marketing drug safety in these countries. This article analyzes the barriers to introducing robust pharmacovigilance systems in developing countries.

    The small social acceptance of nuclear power for power generation suggests that in the present situation nuclear technology does not meet certain sustainable criteria. First, the concept of sustainable development is explained and which dimensions can be distinguished. Next, the sustainable development with regard to the development of the energy supply is outlined and the energy policy to obtain this situation is discussed. Subsequently, the impact of the sustainable development and the policy used to realize this on the nuclear technology are dealt with. As a result, criteria are formulated that can be used to verify how nuclear technology will meet this criteria and which demands should be used to fit this technology so it can be used in a sustainable development of the society. 55 refs

    Technological changes and need for innovation represents the main concerns for organizational growth and profitability. However the main priority is still about achieving high performance through product development and consumers' engagement activities. As implementation of open innovation applications increased and value co — creation became well known and major process, companies were engaged into value co — innovation activities. From this point of view the need for joint efforts with consumers in product development arose. Thus the primary condition for an organization to be consumer centric is to define clear the vision and mission which reflects the common efforts for co — creation and diffusion of innovation. As Research & Development processes evolved and interest for innovative concepts and products arose, companies started to implement the specific instruments for consumers' attraction and engagement into design and product development. The digitalized innovation became the main source for establishing the direct communication with the consumers. In order to achieve organization growth, profitability and recognition, the companies should be aware of the innovation importance and the need for internal change. From this point of view, there is necessary to assess the organizational structures, to implement new policies and to establish strategic targets. Basically it is justified the need for platform occurrence and development. Based on case study of BMW Group, recognised leader in automotive industry for innovative concepts, there will be analysed main features within organizational context which promotes the innovation implementation. There will be provided the review of the BMW Group experience of innovation activities, main consumers' engagement strategies, the values which promote the consumer — centric product development, new opportunities assessment, major policies and concerns. The foreseen result is to understand how companies are

    The purpose of the Active Phasing Experiment, designed under the lead of ESO, is to validate wavefront control concepts for ELT class telescopes. This instrument includes an Active Segmented Mirror, located in a pupil image. It will be mounted at a Nasmyth focus of one of the Unit Telescopes of the ESO VLT. APE contains four different types of phasing sensors, which are developed by Istituto Nazionale di Astrofisica in Arcetri, Instituto Astrofisica Canarias, Laboratoire d'Astrophysique de Marseille and ESO. These phasing sensors can be compared simultaneously under identical optical and environmental conditions. All sensors receive telecentric F/15 beams with identical optical quality and intensity. Each phasing sensor can measure segmentation errors of the active segmented mirror and correct them in closed loop. The phasing process is supervised by an Internal Metrology system developed by FOGALE Nanotech and capable of measuring piston steps with an accuracy of a few nanometers. The Active Phasing Experiment is equipped with a turbulence generator to simulate atmospheric seeing between 0.45 and 0.85 arcsec in the laboratory. In addition, the Active Phasing Experiment is designed to control simultaneously with the phasing corrections the guiding and the active optics of one of the VLT Unit Telescopes. This activity is supported by the European Community (Framework Programme 6, ELT Design Study, contract No 011863).

    2008-01-01

    GSTARS is a series of computer models developed by the U.S. Bureau of Reclamation for alluvial river and reservoir sedimentation studies while the authors were employed by that agency. The first version of GSTARS was released in 1986 using Fortran IV for mainframe computers. GSTARS 2.0 was released in 1998 for personal computer application with most of the code in the original GSTARS revised, improved, and expanded using Fortran IV/77. GSTARS 2.1 is an improved and revised GSTARS 2.0 with graphical user interface. The unique features of all GSTARS models are the conjunctive use of the stream tube concept and of the minimum stream power theory. The application of minimum stream power theory allows the determination of optimum channel geometry with variable channel width and cross-sectional shape. The use of the stream tube concept enables the simulation of river hydraulics using one-dimensional numerical solutions to obtain a semi-two- dimensional presentation of the hydraulic conditions along and across an alluvial channel. According to the stream tube concept, no water or sediment particles can cross the walls of stream tubes, which is valid for many natural rivers. At and near sharp bends, however, sediment particles may cross the boundaries of stream tubes. GSTARS3, based on FORTRAN 90/95, addresses this phenomenon and further expands the capabilities of GSTARS 2.1 for cohesive and non-cohesive sediment transport in rivers and reservoirs. This paper presents the concepts, methods, and techniques used to develop the GSTARS series of computer models, especially GSTARS3. ?? 2008 International Research and Training Centre on Erosion and Sedimentation and the World Association for Sedimentation and Erosion Research.

    2005-01-01

    Full text of publication follows: a quantitative methodology is developed, based on the concepts of hierarchy and synthesis, to integrate and organize information and data. The methodology uses scaling to synthesize experimental data and analytical results, and to provide quantitative criteria for evaluating the effects of various design and operating parameters that influence processes in a complex system such as a nuclear power plant or a related test facility. Synthesis and scaling are performed on three hierarchical levels: the process, component and system levels. Scaling on the process level determines the effect of a selected process on a particular state variable during a selected scenario. At the component level this scaling determines the effects various processes have on a state variable, and it ranks the processes according to their importance by the magnitude of the fractional change they cause on that state variable. At the system level the scaling determines the governing processes and corresponding components, ranking these in the order of importance according to their effect on the fractional change of system-wide state variables. The scaling methodology reveals on all levels the fractional change of state variables and is called therefore the Fractional Scaling Methodology (FSM). FSM synthesizes process parameters and assigns to each thermohydraulic process a dimensionless effect metric Ω = ωt, that is the product of the specific rate of fractional change ω and the characteristic time t. The rate of fractional change ω is the ratio of process transport rate over content of a preserved quantity in a component. The effect metric Ω quantifies the contribution of the process to the fractional change of a state variable in a given component. Ordering of a component effect metrics provides the hierarchy of processes in a component, then in all components and the system. FSM separates quantitatively dominant from minor processes and components and

    2010-01-01

    The aim of an article is to introduce and elaborate on the available literature concerning eyeball development. The information content in the article comes from studies performed on groups of children of different ages. In some analysis study groups were chosen depending on sex. Axial length of the eye, depth of anterior chamber, lens's thickness and vitreous's dimension was defined. Intensive changes of eyeball dimensions progress with age. A period of fast and slow growth of the eye can be discerned. Axial length of the eye, depth of anterior chamber, lens's thickness and vitreous's dimension increase over time. Growth of the axial length is mainly caused by increasing axial length of vitreous cavity. The increase in depth of the anterior chamber plays a lesser role. Girls tend to have shorter eyes compared with boys. Both age and male gender are associated with deeper anterior chambers and larger vitreous cavity. Lens thickness decreases with the growth of the eyeball. However gender does not play a role. Based on current literature, it is difficult exactly indicate what are the standards of eyeball growth in children and youths. To establish these parameters, further studies on the another examination in representative group of children and teenagers are necessary.

    The evolution of nuclear activities and criteria for radiation protection have led to a continuous increase in measures to monitor and control the environment and therefore in the number of determinations required for such purposes. Classical analytical procedures are time-consuming, labor-intense and generate a large amount of waste. The alternative use of sensors for such determinations has seen very limited development. The present study focuses on the evaluation of the behavior of a prototype radiochemical sensor for liquid effluents. The sensor is based on a receptor made of a plastic scintillator and is capable of continuous, on-time and accurate remote quantification of the activity of alpha, beta and beta-gamma emitters. Low-level active solutions of {sup 90}Sr/{sup 90}Y, {sup 238}Pu, {sup 134}Cs and {sup 60}Co in matrices of groundwater, seawater and drinking water were quantified with prediction errors lower than 10% in most cases. The study also yields information about light generation and transmission and transductor configuration that will be useful in the design of future versions of this sensor.

  1. Understanding stakeholder participation in research as part of sustainable development.

    2012-06-30

    Participation is often presented as a 'good' thing and a fairer way to represent views and opinions outside narrow confines of interest and expertise. However, the roots of participatory approaches within research contexts are deep and numerous twists and turns demonstrate a confused and possibly confusing morphology with significant gaps and weaknesses. In this paper 'via the medium' of the POINT (Policy Influence of Indicators) research project we trace elements of the recent history of group participation in sustainable development and the emergence of focus on four areas, most significantly how participatory methods are used. In the absence of strong evidence to contrary we suggest that the issue of how participants engage in participation remains a significant weakness for the field. In order to counter the apparent gap we suggest that a certain degree of structure and process can provide the oeuvre of participatory approaches with a higher degree of transparency in the research process and, by focus on the use of a method called Triple Task, group participatory events can be encouraged to yield greater insights into the workings of groups of all kinds.

    Recent evidence suggests that Medicare Part D increased prescription drug use among seniors, and increased pharmaceutical firms' revenues from sales. Previous studies also indicate that increases in market size induce pharmaceutical innovation. This paper assesses the impact of the Medicare Part D legislation on pharmaceutical research and development (R&D), using time-series data on the number of drugs entering preclinical and clinical development by therapeutic class and phase. We find that the passage and implementation of Medicare Part D is associated with significant increases in pharmaceutical R&D for therapeutic classes with higher Medicare market share.

  10. Use of configuration management to reduce development costs in metal parts

    International Nuclear Information System (INIS)

    Kalsoom, T.; Ahmad, S.

    2005-01-01

    In development and manufacturing phases of metal parts, design efforts are converted in set of engineering data pack under the given guidelines of Configuration Management (CM). These engineering documents define Configuration Management of metal parts production in a local industry. The development phase is normally less structured and open to Engineering Change Proposals. In our local engineering organizations most of the work done is normally not well documented for future revisions and modernization. This leads to delays in development and increase in production costs of metal parts. This becomes more pronounced if any member of the design team disassociates and leaves the organization. The Configuration Management helps to reduce development costs by providing infrastructure for product identification, documentation, change control, interface control and technical reviews and product audits. Automated or Computer-Assisted CM activities can also be used to shorten response time and increase accuracy and reliability of the produced metal components. (author)

    The concept of developing talent and athleticism in youth is the goal of many coaches and sports systems. Consequently, an increasing number of sporting organizations have adopted long-term athletic development models in an attempt to provide a structured approach to the training of youth. It is clear that maximizing sporting talent is an important goal of long-term athletic development models. However, ensuring that youth of all ages and abilities are provided with a strategic plan for the development of their health and physical fitness is also important to maximize physical activity participation rates, reduce the risk of sport- and activity-related injury, and to ensure long-term health and well-being. Critical reviews of independent models of long-term athletic development are already present within the literature; however, to the best of our knowledge, a comprehensive examination and review of the most prominent models does not exist. Additionally, considerations of modern day issues that may impact on the success of any long-term athletic development model are lacking, as are proposed solutions to address such issues. Therefore, within this 2-part commentary, Part 1 provides a critical review of existing models of practice for long-term athletic development and introduces a composite youth development model that includes the integration of talent, psychosocial and physical development across maturation. Part 2 identifies limiting factors that may restrict the success of such models and offers potential solutions.

    Loose parts are produced by being parted from the structure of the reactor coolant system or by coming into RCS from the outside during test operation, refueling, and overhaul time. These loose parts are mixed with reactor coolant fluid and collide with RCS components. When loose parts are occurred within RCS, it is necessary to estimate the impact point and the mass of loose parts. In this report an analysis algorithm for the estimation of the impact point and mass of loose part is developed. The developed algorithm was tested with the impact test data of Yonggwang-3. The estimated impact point using the proposed algorithm in this report had 5 percent error to the real test data. The estimated mass was analyzed within 28 percent error bound using the same unit's data. We analyzed the characteristic frequency of each sensor because this frequency effected the estimation of impact point and mass. The characteristic frequency of the background noise during normal operation was compared with that of the impact test data. The result of the comparison illustrated that the characteristic frequency bandwidth of the impact test data was lower than that of the background noise during normal operation. by the comparison, the integrity of sensor and monitoring system could be checked, too.

    1997-12-01

    The National Aeronautics & Space Administration (NASA), the European Space Agency (ESA), and the Canadian Space Agency (CSA) missions involve the performance of scientific experiments in Space. Instruments used in such experiments are fabricated using electronic parts such as microcircuits, inductors, capacitors, diodes, transistors, etc. For instruments to perform reliably the selection of commercial parts must be monitored and strictly controlled. The process used to achieve this goal is by a manual review and approval of every part used to build the instrument. The present system to select and approve parts for space applications is manual, inefficient, inconsistent, slow and tedious, and very costly. In this dissertation a computer based decision support model is developed for implementing this process using artificial intelligence concepts based on the current information (expert sources). Such a model would result in a greater consistency, accuracy, and timeliness of evaluation. This study presents the methodology of development and features of the model, and the analysis of the data pertaining to the performance of the model in the field. The model was evaluated for three different part types by experts from three different space agencies. The results show that the model was more consistent than the manual evaluation for all part types considered. The study concludes with the cost and benefits analysis of implementing the models and shows that implementation of the model will result in significant cost savings. Other implementation details are highlighted.

  17. A compositional multiphase model for groundwater contamination by petroleum products: 1. Theoretical considerations

    Science.gov (United States)

    Corapcioglu, M. Yavuz; Baehr, Arthur L.

    1987-01-01

    A mathematical model is developed to describe the fate of hydrocarbon constituents of petroleum products introduced to soils as an immiscible liquid from sources such as leaking underground storage tanks and ruptured pipelines. The problem is one of multiphase transport (oil (immiscible), air, and water phases) of a reactive contaminant with constituents such as benzene, toluene, and xylene found in refined petroleum products like gasoline. In the unsaturated zone, transport of each constituent can occur as a solute in the water phase, vapor in the air phase, and as an unaltered constituent in the oil phase. Additionally, the model allows for adsorption. Molecular transformations, microbially mediated or abiotic, are incorporated as sink terms in the conservation of mass equations. An equilibrium approximation, applicable to any immiscible organic contaminant is applied to partition constituent mass between the air, oil, water, and adsorbed phases for points in the region where the oil phase exists. Outside the oil plume the equilibrium approximation takes on a simpler form to partition constituent mass between the air, water, and adsorbed phases only. Microbial degradation of petroleum products is first discussed in a general model, then the conservation of mass equation for oxygen is incorporated into the analysis which takes advantage of the key role played by oxygen in the metabolism of hydrocarbon utilizing microbes in soil environments. Approximations to two subproblems, oil plume establishment in the unsaturated zone, and solute and vapor transport subsequent to immiscible plume establishment are then developed from the general model.

    2008-01-01

    The Tyndall decarbonisation scenarios project has outlined alternative pathways whereby a 60% reduction in CO 2 emissions from 1990 levels by 2050, a goal adopted by the UK Government, can be achieved. This paper, Part I of a two part paper, describes the methodology used to develop the scenarios and outlines the motivations for the project. The study utilised a backcasting approach, applied in three phases. In phase one, a set of credible and consistent end-points that described a substantially decarbonised energy system in 2050 were generated and reviewed by stakeholders. In phase two, pathways were developed to achieve the transition to the desired end-point. The impacts of the scenarios were assessed in phase three, by means of a deliberative multi-criteria assessment framework. The scenarios to emerge from this process are elaborated in Part II, and conclusions drawn in relation to the feasibility of achieving the 60% target

    2018-05-01

    Originally developed decades ago, the binder jetting additive manufacturing (BJ-AM) process possesses various advantages compared to other additive manufacturing (AM) technologies such as broad material compatibility and technological expandability. However, the adoption of BJ-AM has been limited by the lack of knowledge with the fundamental understanding of the process principles and characteristics, as well as the relatively few systematic design guideline that are available. In this work, the process design considerations for BJ-AM in green part fabrication were discussed in detail in order to provide a comprehensive perspective of the design for additive manufacturing for the process. Various process factors, including binder saturation, in-process drying, powder spreading, powder feedstock characteristics, binder characteristics and post-process curing, could significantly affect the printing quality of the green parts such as geometrical accuracy and part integrity. For powder feedstock with low flowability, even though process parameters could be optimized to partially offset the printing feasibility issue, the qualities of the green parts will be intrinsically limited due to the existence of large internal voids that are inaccessible to the binder. In addition, during the process development, the balanced combination between the saturation level and in-process drying is of critical importance in the quality control of the green parts.

  7. Making mental health an integral part of sustainable development: the contribution of a social determinants framework.

    Science.gov (United States)

    De Silva, M J

    2015-04-01

    There have been repeated calls to include mental health in the sustainable development goals (SDGs), arguing that progress in development will not be made without improvements in mental health. Although these calls are starting to gain political traction, currently only a tiny fraction of international development work includes mental health. A social determinants framework may be useful in incorporating mental health into sustainable development because it promotes a multi-sectorial and multi-disciplinary approach which is the corner stone of good development practice. Two approaches are suggested to make mental health a part of sustainable development: (1) integrate mental health into existing development programmes to promote social and economic environments that prevent mental health problems developing; (2) ensure that mental health programmes are better at promoting sustainable development by preventing the negative social and economic consequences of mental illness. Real-world examples of these approaches are provided. To achieve this, the mental health impact of wider development programmes, and the social and economic consequences of mental health interventions, must be evaluated. Development agencies should ensure that they have equity for mental health in all their policies, and investment must be increased for those mental health prevention, promotion and treatment programmes which have the greatest impact on sustainable development. The SDGs bring the promise of a more holistic approach to development. It is now the task of global mental health to demonstrate not just that mental health is an integral part of sustainable development, but that affordable and effective solutions exist which can improve mental health and development more broadly.

    The development and testing of a simple mechanical stemming aid is described. The aid comprises a solid unit placed in the stemming above the explosive column and is designed to improve blasting efficiency and reduce drilling and blasting costs. It is designed to work with back filled drill cuttings or any other suitable stemming material. To date it has consisted of the testing of the aid in small diameter (1.5 and 1.625 inch) holes in Jefferson City Dolomite for both bench and crater blasting configurations. Full scale field trials are being conducted nearby in similar rock in an aggregate quarry. The data acquisition equipment used in Phase 1 included both a Spin Physics SP2000 high speed video motion analysis system and acoustic and seismic monitoring units. Measurements for each test included peak air over pressure, ground surface ppv, stemming displacement and velocity and face movement and extent. The results illustrate that the concept is sound and that its successful application to production blasting at full scale will be a function of manufacturing cost, the development of suitable insertion techniques for large diameter boreholes and the selection of a suitable low cost material for the aid. 17 refs., 20 figs.

    Preceptors are expected to have the skills to be able to form an effective learning environment and facilitate a constructive clinical learning experience for students and new employees. Internationally, access to education for preceptors varies, with preceptors worldwide requesting more education in preceptorship. This article is based on a two-part study focusing on both the development and evaluation of a continuous, credit-bearing professional development course. The aim of this part of the study was to investigate and include preceptors' requests and educational needs when developing a continuous professional development course on an advanced level. This study used a qualitative research approach. In total, 64 preceptors (62 women and two men) answered one single written, self-administered global question online. The participants were all interested in teaching and had completed an undergraduate training in preceptorship. The collected data was analysed by content analysis inspired by Burnard's description of the method. The participating preceptors illuminated two main themes: 'Tools for effective precepting of students and healthcare professionals' and 'in-depth knowledge and understanding of preceptorship in an academic setting'. The results suggest that vital components for preceptor preparation could be a) teaching and learning strategies, b) reflective and critical reasoning, c) communication models, d) the role of the preceptor, and e) preceptorship. Using the results from this study as a guide, a continuous professional development course was designed to assist preceptors in deepening their knowledge of preceptorship in regard to planning, leading and implementing educational activities directed at students, healthcare professionals, patients and their families. The course content focuses on skills needed for preceptorship and is based on adult learning principles. A continuous, credit-bearing professional development course must include an exam by

    2014-01-01

    Highlights: • The piston-driven laminar pulsating flow in a pipe is studied. • Fully developed flow is examined analytically, numerically and experimentally. • An increase in F results an increase in the amplitude of the centerline velocity. • The characters of the radial velocity profiles critically depend on both the frequency and the phase angle. • The near/off-wall flow reversals are observed for F = 105, 226 and 402. - Abstract: Piston-driven pulsating flow is a specific type of pressure-driven pulsating flows. In this study, piston-driven laminar pulsating flow in a pipe is studied. This study mainly exists of two parts: developing flow and fully developed flow. In this part, hydrodynamically fully developed flow is examined analytically, numerically and experimentally. A constant value of the time-averaged Reynolds number is considered, Re = 1000. In the theoretical studies, both analytical and numerical, an inlet velocity profile representing the experimental case, i.e., the piston driven flow, is assumed. In the experiments, in the hydrodynamically fully developed region, radial velocity distribution and pressure drop are obtained using hot-wire anemometer and pressure transmitter, respectively. The effect pulsation frequency on the friction coefficient as well as velocity profiles are obtained. A good agreement is observed among analytical, numerical and experimental results

    The reliability engineering predicts modes of failures and weak links before the system is built instead of failure case study. The reliability engineering analysis will help in the manufacturing economy, assembly accuracy and qualification by testing, leading to production of metal parts in an aerospace industry. This methodology will also minimize the performance constraints in any requirement for the application of metal components in aerospace systems. The reliability engineering predicts the life of the parts under loading conditions whether dynamic or static. Reliability predictions can help engineers in making decisions about design of components, materials selection and qualification under applied stress levels. Two methods of reliability prediction i.e. Part Stress Analysis and Part Count have been used in this study. In this paper we will discuss how these two methods can be used to measure reliability of a system during development phases, which includes the measuring effect of environmental and operational variables. The equations are used to measure the reliability of each type of component, as well as, integration for measuring system applied for the reliability analysis. (author)

    Production lead time is one of the key measures to assess whether a production system is running well or not. A short lead time will lead to higher customer satisfaction and will be a solid proof that a system is well-organized. To shorten the production lead time, a good production planning and control are required. There are many obstacles which can occur at any time, for instance shortage of material and worker, or poor production scheduling. Service Parts Planning Department works with many parties from the beginning of service parts production until it is delivered to the customer. This research was conducted to find an appropriate production monitoring tool for Service Parts Planning Department, which is a control method that make problems appears to the surface and can be overcome quickly so that the production process can run normally. The tool development started with a field study to find out the production flow from start to finish, a literature review and a interview with some employees who will later use the production control tool, and the creation of a daily control that went through several modifications until finally meet the needs of the department. In this research, a production monitoring tool which is developed can be used to monitor the entire order status, the production lead time, and also serves as the records and reports for presentation.

    The technology of the selective laser melting (SLM) allows making products from powders of aluminum, titanium, heat-resistant alloys and stainless steels. Today the use of SLM technology develops at manufacture of the functional parts. This in turn requires development of a methodology projection of technological processes (TP) for manufacturing parts including databases of standard TP. Use of a technique will allow to exclude influence of technologist’s qualification on made products quality, and also to reduce labor input and energy consumption by development of TP due to use of the databases of standard TP integrated into a methodology. As approbation of the developed methodology the research of influence of the modes of a laser emission on a roughness of a surface of synthesized material was presented. It is established that the best values of a roughness of exemplars in the longitudinal and transversal directions make 1.98 μm and 3.59 μm respectively. These values of a roughness were received at specific density of energy 6.25 J/mm2 that corresponds to power and the speed of scanning of 200 W and 400 mm/s, respectively, and a hatch distance of 0.08 mm.

    Sivertsen, Terje

    1996-01-01

    This report describes the formal development of a new version of the HRP Prover. The new version of the tool will have functionality almost identical to the current version, but is developed in accordance to established principles for applying algebraic specification in formal software development. The development project provides results of relevance to the formal development of a wide range of language-oriented tools, including programming language compilers, as well as to the automatic generation of code from specifications. Since the overall scope of this report is the analysis of algebraic specifications, emphasis is given to topics related to what is usually understood as the ''front end'' of compilers. This includes lexical and syntax analysis of the specifications, static semantics through type checking, and dynamic semantics through evaluation. All the different phases are specified in algebraic specification and supported by the current version of the HRP Prover. In subsequent work, the completed parts of the new version will complement the tool support in the development. The work presented will be followed up by formal specification of theorem proving and transformation, as well as code generation into conventional programming languages. The new version of the HRP Prover is incrementally developed in coherence with the specifications produced in these activities. At the same time, the development of the tool demonstrates the efficient use of the methodology through real application on an increasingly important class of software. (author)

    Natural gas has known a rapid development in the French-speaking part of Switzerland and this trend is still continuing. Natural gas represents 13% of the overall energy consumption, which lies significantly above the Swiss average and, in the year 2000, it should reach about 20%. In order to meet the expected growth of consumption, Gaznat has already contracted, under long term agreements, large quantities of natural gas from diversified sources. Underground storage capacities in nearby France have been considerably increased and new gas-pipelines are being built. These pipelines will enable to double the supply capacity of the French-speaking part of Switzerland within the next three years. (orig.) [de

    The U.S. Space Exploration Policy has as a cornerstone the establishment of an outpost on the moon. This lunar outpost wil1 eventually provide the necessary planning, technology development, testbed, and training for manned missions in the future beyond the Moon. As part of the overall activity, the National Aeronautics and Space Administration (NASA) is investigating how the in situ resources can be utilized to improve mission success by reducing up-mass, improving safety, reducing risk, and bringing down costs for the overall mission. Marshall Space Flight Center (MSFC), along with other NASA centers, is supporting this endeavor by exploring how lunar regolith can be mined for uses such as construction, life support, propulsion, power, and fabrication. An infrastructure capable of fabrication and nondestructive evaluation will be needed to support habitat structure development and maintenance, tools and mechanical parts fabrication, as well as repair and replacement of space-mission hardware such as life-support items, vehicle components, and crew systems, This infrastructure will utilize the technologies being developed under the In Situ Fabrication and Repair (ISFR) element, which is working in conjunction with the technologies being developed under the In Situ Resources Utilization (ISRU) element, to live off the land. The ISFR Element supports the Space Exploration Initiative by reducing downtime due to failed components; decreasing risk to crew by recovering quickly from degraded operation of equipment; improving system functionality with advanced geometry capabilities; and enhancing mission safety by reducing assembly part counts of original designs where possible. This paper addresses the need and plan for understanding the properties of the lunar regolith to determine the applicability of using this material in a fabrication process. This effort includes the development of high fidelity simulants that will be used in fabrication processes on the ground to

  4. The importance of scenario development in meeting 40 CFR part 191

    International Nuclear Information System (INIS)

    Hunter, R.L.

    1988-01-01

    Scenario development and screening is a fundamental part of performance assessment, but its importance in satisfying 40 CFR Part 191 (the standard) is sometimes underestimated. The first step in scenario development in support of performance assessment for the standard's containment requirements is to identify a set of potentially disruptive events and processes. This set must be broad enough to allow the identification, as required by the standard, of those processes and events that might affect the disposal system; data can then be collected on the scenarios identified in this step. The standard also requires that releases be estimated for all significant processes and events; thus the final step in scenario development is systematically screening the scenarios, on the basis of their probabilities and consequences, to select those that are important enough to be modeled in detail. In general, a few hundred scenarios for the release of radionuclides from a nuclear-waste repository can be identified, but only a few of these can or should be modeled in detail

    Results of an extensive development program aimed at making three, separate, structural components from beryllium, using sheet-metal fabrication methods, are presented. Ingot-source beryllium sheet at thicknesses of 0.100, 0.125, and 0.170 inch is formed in a fully-recrystallized and in a partially-recrystallized condition. The tensile yield strength is 26,000 psi after full recrystallization. After partial recrystallization, tensile yield strength is between 35,000 and 45,000 psi, depending upon sheet thickness, heat treat temperature, and time at temperature. The high yield strength is retained in the parts after forming. (U.S.)

    The establishment of the technology that inspects plant structures nondestructive is requested, because the occurrence of cracks is reported in the structures of nuclear power plants. In this research, a uniform eddy current multi-probe that is able to be applied to the complex structure and inspected the cracks at the high speed was developed. Exciting coils of the uniform eddy current multi-probe were designed the shape that agreed with the complex shape part, and so that the eddy current flows uniformly in the part of pick-up coils. The pick-up coils were arranged on a flexible printed circuit board as it was possible to correspond to the complex shape. The detection characteristics of EDM (electro-discharge machining) slits provided on the complex shape part were evaluated. The clear signals for the EDM slits provided on the curvature surface of 25 mm in radius were obtained by this probe. We confirmed that the crack shape was able to be estimated by the detection signals. (author)

    Full Text Available Abstract Hazard Analysis and Critical Control Points (HACCP systems are a risk based preventive approach developed to increase levels of food safety assurance. This is part 1 of a pilot study on the development, implementation and evaluation of a HACCP-based approach for the control of good udder health in dairy cows. The paper describes the use of a novel approach based on a deconstruction of the infectious process in mastitis to identify Critical Control Points (CCPs and develop a HACCP-based system to prevent and control mastitis in dairy herds. The approach involved the creation of an Infectious Process Flow Diagram, which was then cross-referenced to two production process flow diagrams of the milking process and cow management cycle. The HACCP plan developed, may be suitable for customisation and implementation on dairy farms. This is a logical, systematic approach to the development of a mastitis control programme that could be used as a template for the development of control programmes for other infectious diseases in the dairy herd.

    Full Text Available Experience in application of multi-operational machines CNC (MOM CNC shows that they are efficient only in case of significantly increasing productivity and dramatically reducing time-to-market cycle of new products. Most full technological MOM capabilities are revealed when processing the complex body parts. The more complex is a part design and the more is its number of machined surfaces, the more tools are necessary for its processing and positioning, the more is an efficiency of their application. At the same time, the case history of using these machines in industry shows that MOM CNC are, virtually, used mostly for technological processes of universal equipment, which is absolutely unacceptable. One way to improve the processing performance on MOM CNC is to reduce nonproductive machine time through reducing the mutual idle movements of the working machine. This problem is solved using dynamic programming methods, one of which is the solution of the traveling salesman problem (Bellman's method. With a known plan for treatment of all elementary surfaces of the body part, i.e. the known number of performed transitions, each transition is represented as a vertex of some graph, while technological links between the vertices are its edges. A mathematical model is developed on the Bellman principle, which is adapted to technological tasks to minimize the idle time of mutual idle movements of the working machine to perform all transitions in the optimal sequence. The initial data to fill matrix of time expenditures are time consumed by the hardware after executing the i-th transition, and necessary to complete the j-transition. The programmer fills in matrix cells according to known routing body part taking into account the time for part and table positioning, tool exchange, spindle and table approach to the working zone, and the time of table rotation, etc. The mathematical model was tested when machining the body part with 36 transitions on the

    1990-01-01

    This paper reports that the demand for stable, low-concentration multicomponent standards of volatile toxic organic compounds for quantifying national and state measurement of ambient air quality and hazardous waste incineration emissions has markedly increased in recent years. In response to this demand, a microgravimetric technique was developed and validated for preparing such standards; these standards ranged in concentration from several parts per million (ppm) down to one part per billion (ppb) and in complexity from one organic up to 17. Studies using the gravimetric procedure to prepare mixtures of different groups of organics. including multi-components mixtures in the 5 to 20 ppb range, revealed a very low imprecision. This procedure is based on the separate gravimetric introduction of individual organics into an evacuated gas cylinder, followed by the pressurized addition of a precalculated amount of pure nitrogen. Additional studies confirmed the long-term stability of these mixtures. The uncertainty of the concentrations of the individual organics at the 95% confidence level ranged from less than 1% relative at 1 ppm to less than 10% relative at 1 ppb. Over 100 primary gravimetric standards have been developed, validated, and used for certifying the concentrations of a variety of mixtures for monitoring studies

    An experimental study of two real multi-hole Diesel injectors is performed under current DI Diesel engine operating conditions. The aim of the investigation is to study the influence of injector technology on the flow at the nozzle exit and to analyse its effect on the spray in evaporative conditions and combustion development. The injectors used are two of the most common technologies used nowadays: solenoid and piezoelectric. The nozzles for both injectors are very similar since the objective of the work is the understanding of the influence of the injector technology on spray characteristics for a given nozzle geometry. In the first part of the study, experimental measurements of hydraulic characterization have been analyzed for both systems. Analysis of spray behaviour in evaporative conditions and combustion development will be carried out in the second part of the work. Important differences between both injectors have been observed, especially in their transient opening and closing of the needle, leading to a more efficient air-fuel mixing and combustion processes for the piezoelectric actuated injector.

  18. Developing maximal neuromuscular power: Part 1--biological basis of maximal power production.

    Science.gov (United States)

    Cormie, Prue; McGuigan, Michael R; Newton, Robert U

    2011-01-01

    This series of reviews focuses on the most important neuromuscular function in many sport performances, the ability to generate maximal muscular power. Part 1 focuses on the factors that affect maximal power production, while part 2, which will follow in a forthcoming edition of Sports Medicine, explores the practical application of these findings by reviewing the scientific literature relevant to the development of training programmes that most effectively enhance maximal power production. The ability of the neuromuscular system to generate maximal power is affected by a range of interrelated factors. Maximal muscular power is defined and limited by the force-velocity relationship and affected by the length-tension relationship. The ability to generate maximal power is influenced by the type of muscle action involved and, in particular, the time available to develop force, storage and utilization of elastic energy, interactions of contractile and elastic elements, potentiation of contractile and elastic filaments as well as stretch reflexes. Furthermore, maximal power production is influenced by morphological factors including fibre type contribution to whole muscle area, muscle architectural features and tendon properties as well as neural factors including motor unit recruitment, firing frequency, synchronization and inter-muscular coordination. In addition, acute changes in the muscle environment (i.e. alterations resulting from fatigue, changes in hormone milieu and muscle temperature) impact the ability to generate maximal power. Resistance training has been shown to impact each of these neuromuscular factors in quite specific ways. Therefore, an understanding of the biological basis of maximal power production is essential for developing training programmes that effectively enhance maximal power production in the human.

    2013-01-01

    design (QbD) is a concept that is currently struggling for more acceptance from the side of the pharmaceutical industry. To achieve this, the major goals of QbD have to be revisited and QbD tools have to be subsequently developed. This contribution offers an example as to how implement risk management in early-stage biosimilar development as part of the QbD concept. The main goal was to go beyond the conventional QbD workflow and to adjust risk management to the challenges of biosimilar products. Accordingly, instead of using methods like failure mode and effects analysis, recommendations of the ICH Q9 guideline were reviewed and put into practice by creating tailored risk assessment tools. The novelty of this contribution is to report those tailored tools ready-to-use for early bioprocess development of biosimilars along QbD principles.

    Cosma, C.; Heikkinen, P.; Pekonen, S.

    1991-05-01

    The purpose of the high resolution borehole seismics project has been to improve the reliability and resolution of seismic methods in the particular environment of nuclear waste repository sites. The results obtained, especially the data processing and interpretation methods developed, are applicable also to other geophysical methods (e.g. Georadar). The goals of the seismic development project have been: the development of processing and interpretation techniques for mapping fractured zones, and the design and construction of a seismic source complying with the requirements of repository site characterization programs. Because these two aspects of the work are very different in nature, we have structured the report as two self contained parts. Part 1 describes the development of interpretive techniques. We have used for demonstrating the effect of different methods a VSP data set collected at the SCV site during Stage 1 of the project. Five techniques have been studied: FK-filtering, three versions of Tau-p filtering and a new technique that we have developed lately, Image Space filtering. Part 2 refers to the construction of the piezoelectric source. Earlier results obtained over short distances with low energy piezoelectric transmitters let us believe that the same principle could be applied for seismic signal transmitters, if solutions for higher energy and lower frequency output were found. The instrument which we have constructed is a cylindrical unit which can be placed in a borehole and is able to produce a radial strain when excited axially. The minimum borehole diameter is 56 mm.

    © 2015 Elsevier Ltd and IIR.All rights reserved. The ejector refrigeration machine (ERM) offers several advantages over other heat-driven refrigeration machine, including simplicity in design and operation, high reliability and low installation cost, which enable its wide application in the production of cooling. In this paper the theoretical analysis of ejector design and ejector refrigeration cycle performance is presented. It is shown that ERM performance characteristics depend strongly on the operating conditions, the efficiency of the ejector used, and the thermodynamic properties of the refrigerant used. A 1-D model for the prediction of the entrainment ratio ω, and an optimal design for ejectors with cylindrical and conical-cylindrical mixing chambers are presented in this paper. In order to increase ERM performance values, it is necessary first of all to improve the performance of the ejector.

  3. Promoting physical therapists’ of research evidence to inform clinical practice: part 1 - theoretical foundation, evidence, and description of the PEAK program

    Science.gov (United States)

    2014-01-01

    Background There is a need for theoretically grounded and evidence-based interventions that enhance the use of research evidence in physical therapist practice. This paper and its companion paper introduce the Physical therapist-driven Education for Actionable Knowledge translation (PEAK) program, an educational program designed to promote physical therapists’ integration of research evidence into clinical decision-making. The pedagogical foundations for the PEAK educational program include Albert Bandura’s social cognitive theory and Malcolm Knowles’s adult learning theory. Additionally, two complementary frameworks of knowledge translation, the Promoting Action on Research Implementation in Health Services (PARiHS) and Knowledge to Action (KTA) Cycle, were used to inform the organizational elements of the program. Finally, the program design was influenced by evidence from previous attempts to facilitate the use of research in practice at the individual and organizational levels. Discussion The 6-month PEAK program consisted of four consecutive and interdependent components. First, leadership support was secured and electronic resources were acquired and distributed to participants. Next, a two-day training workshop consisting of didactic and small group activities was conducted that addressed the five steps of evidence based practice. For five months following the workshop, participants worked in small groups to review and synthesize literature around a group-selected area of common clinical interest. Each group contributed to the generation of a “Best Practices List” - a list of locally generated, evidence-based, actionable behaviors relevant to the groups’ clinical practice. Ultimately, participants agreed to implement the Best Practices List in their clinical practice. Summary This, first of two companion papers, describes the underlying pedagogical theories, knowledge translation frameworks, and research evidence used to derive the PEAK program – an educational program designed to promote the use of research evidence to inform physical therapist practice. The four components of the program are described in detail. The companion paper reports the results of a mixed methods feasibility analysis of this complex educational intervention. PMID:24965501

The pedagogical foundations for the PEAK educational program include Albert Bandura's social cognitive theory and Malcolm Knowles's adult learning theory. Additionally, two complementary frameworks of knowledge translation, the Promoting Action on Research Implementation in Health Services (PARiHS) and Knowledge to Action (KTA) Cycle, were used to inform the organizational elements of the program. Finally, the program design was influenced by evidence from previous attempts to facilitate the use of research in practice at the individual and organizational levels. The 6-month PEAK program consisted of four consecutive and interdependent components. First, leadership support was secured and electronic resources were acquired and distributed to participants. Next, a two-day training workshop consisting of didactic and small group activities was conducted that addressed the five steps of evidence based practice. For five months following the workshop, participants worked in small groups to review and synthesize literature around a group-selected area of common clinical interest. Each group contributed to the generation of a "Best Practices List" - a list of locally generated, evidence-based, actionable behaviors relevant to the groups' clinical practice. Ultimately, participants agreed to implement the Best Practices List in their clinical practice. This, first of two companion papers, describes the underlying pedagogical theories, knowledge translation frameworks, and research evidence used to derive the PEAK program - an educational program designed to promote the use of research evidence to inform physical therapist practice. The four components of the program are described in detail. The companion paper reports the results of a mixed methods feasibility analysis of this complex educational intervention.

    To determine the optimal situation for the energy supply in the working area of the IJsselmij and Sep the study on the title subject was carried out. To influence the energy demand demand-side management (DSM) as part of integrated resource planning (IRP) is applied. Several scenarios to determine whether new production capacity must be installed or conservation options and activities should be realized are elaborated and calculated by means of the COMPASS model. E3T compiled input data for the demand-side of the model: energy consumption and energy conservation, investment cost and operational cost per user, number of installations and the development of the penetration of the conservation options between 1990 and 2010, and required subsidies and promotional costs of the IJsselmij to introduce such options. Six of the options were selected and elaborated in detail. The results are presented in this report for the options: coverage of cooling and freezing equipment at night, frequency control of electric motors, decentralized heat production by means of advanced burners, indoor climate control in the built environment, reflectors for TL-lighting systems in the built environment, and behavioral change in industrial companies. In part 1 an overview is given of the economics, the selection and elaboration of the energy conservation options. 9 figs., 53 tabs., 71 refs., 1 appendix

    Since the use of standard engineering methods in the process of an ice bank performance evaluation offers neither adequate flexibility nor accuracy, the aim of this research was to provide a powerful tool for an industrial design of an ice storage system allowing to account for the various design parameters and system arrangements over a wide range of time varying operating conditions. In this paper the development of a computer application for the prediction of an ice bank system operation is presented. Static, indirect, cool thermal storage systems with external ice on coil building/melting were considered. The mathematical model was developed by means of energy and mass balance relations for each component of the system and is basically divided into two parts, the model of an ice storage system and the model of a refrigeration unit. Heat transfer processes in an ice silo were modelled by use of empirical correlations while the performance of refrigeration unit components were based on manufacturers data. Programming and application design were made in Fortran 95 language standard. Input of data is enabled through drop down menus and dialog boxes, while the results are presented via figures, diagrams and data (ASCII) files. In addition, to demonstrate the necessity for development of simulation program a case study was performed. Simulation results clearly indicate that no simple engineering methods or rule of thumb principles could be utilised in order to validate performance of an ice bank system properly. (author)

    The energy future has become one of the major stakes of the next presidential election in France. After the Fukushima disaster, the debates on our own energy future mainly cover the closing down, or not, in full or in part, of nuclear power stations. Natural gas is, most of the time, absent from the debate. Yet it has many advantages and should be viewed as a solution that favours renewable energy development, while being essential to achieving a more diversified and more environment-friendly energy mix. In addition, our country is at the crossroads of different European as networks. Given this situation, GRTGaz is doing its utmost to develop an attractive and dynamic wholesale market. With the prospect of increased European market integration and in spite of an uncertain economic environment, investments must be made to develop infrastructure. In 2011, with the financial backing of the European Union, GRTGaz has launched two major gas transport grid reinforcement projects in the South and North of France. These will allow us to strengthen our position as one the major gas hubs in Europe. This is good news for our industry and for employment too. (author)

  13. Development of Spray on Bag for manufacturing of large composites parts: Diffusivity analysis

    Science.gov (United States)

    Dempah, Maxime Joseph

    Bagging materials are utilized in many composites manufacturing processes. The selection is mainly driven by cost, temperature requirements, chemical compatibility and tear properties of the bag. The air barrier properties of the bag are assumed to be adequate or in many cases are not considered at all. However, the gas barrier property of a bag is the most critical parameter, as it can negatively affect the quality of the final laminate. The barrier property is a function of the bag material, uniformity, thickness and temperature. Improved barrier properties are needed for large parts, high pressure consolidated components and structures where air stays entrapped on the part surface. The air resistance property of the film is defined as permeability and is investigated in this thesis. A model was developed to evaluate the gas transport through the film and an experimental cell was implemented to characterize various commercial films. Understanding and characterizing the transport phenomena through the film allows optimization of the bagging material for various manufacturing processes. Spray-on-Bag is a scalable alternative bagging method compared to standard films. The approach allows in-situ fabrication of the bag on large and complex geometry structures where optimization of the bag properties can be varied on a local level. An experimental setup was developed and implemented using a six axis robot and an automated spraying system. Experiments were performed on a flat surface and specimens were characterized and compared to conventional films. Air barrier properties were within range of standard film approaches showing the potential to fabricate net shape bagging structures in an automated process.

    This is the second of two papers reporting the results of a major study considering 'operator models' for municipal solid waste management (MSWM) in emerging and developing countries. Part A documents the evidence base, while Part B presents a four-step decision support system for selecting an appropriate operator model in a particular local situation. Step 1 focuses on understanding local problems and framework conditions; Step 2 on formulating and prioritising local objectives; and Step 3 on assessing capacities and conditions, and thus identifying strengths and weaknesses, which underpin selection of the operator model. Step 4A addresses three generic questions, including public versus private operation, inter-municipal co-operation and integration of services. For steps 1-4A, checklists have been developed as decision support tools. Step 4B helps choose locally appropriate models from an evidence-based set of 42 common operator models ( coms); decision support tools here are a detailed catalogue of the coms, setting out advantages and disadvantages of each, and a decision-making flowchart. The decision-making process is iterative, repeating steps 2-4 as required. The advantages of a more formal process include avoiding pre-selection of a particular com known to and favoured by one decision maker, and also its assistance in identifying the possible weaknesses and aspects to consider in the selection and design of operator models. To make the best of whichever operator models are selected, key issues which need to be addressed include the capacity of the public authority as 'client', management in general and financial management in particular.

    The use of social networking sites is increasingly being adopted in public health, in part, because of the barriers to funding and reduced resources. Public health professionals are using social media platforms, specifically Twitter, as a way to facilitate professional development. The objective of this study was to identify public health professionals using Twitter and to analyze how they use this platform to enhance their formal and informal professional development within the context of public health. Keyword searches were conducted to identify and invite potential participants to complete a survey related to their use of Twitter for public health and professional experiences. Data regarding demographic attributes, Twitter usage, and qualitative information were obtained through an anonymous Web-based survey. Open-response survey questions were analyzed using the constant comparison method. "Using Twitter makes it easier to expand my networking opportunities" and "I find Twitter useful for professional development" scored highest, with a mean score of 4.57 (standard deviation [SD] 0.74) and 4.43 (SD 0.76) on a 5-point Likert scale. Analysis of the qualitative data shows the emergence of the following themes for why public health professionals mostly use Twitter: (1) geography, (2) continuing education, (3) professional gain, and (4) communication. For public health professionals in this study, Twitter is a platform best used for their networking and professional development. Furthermore, the use of Twitter allows public health professionals to overcome a series of barriers and enhances opportunities for growth. ©Mark Hart, Nichole E Stetten, Sabrina Islam, Katherine Pizarro.

  16. Data-Mining Toolset Developed for Determining Turbine Engine Part Life Consumption

    Science.gov (United States)

    Litt, Jonathan S.

    2003-01-01

    The current practice in aerospace turbine engine maintenance is to remove components defined as life-limited parts after a fixed time, on the basis of a predetermined number of flight cycles. Under this schedule-based maintenance practice, the worst-case usage scenario is used to determine the usable life of the component. As shown, this practice often requires removing a part before its useful life is fully consumed, thus leading to higher maintenance cost. To address this issue, the NASA Glenn Research Center, in a collaborative effort with Pratt & Whitney, has developed a generic modular toolset that uses data-mining technology to parameterize life usage models for maintenance purposes. The toolset enables a "condition-based" maintenance approach, where parts are removed on the basis of the cumulative history of the severity of operation they have experienced. The toolset uses data-mining technology to tune life-consumption models on the basis of operating and maintenance histories. The flight operating conditions, represented by measured variables within the engine, are correlated with repair records for the engines, generating a relationship between the operating condition of the part and its service life. As shown, with the condition-based maintenance approach, the lifelimited part is in service until its usable life is fully consumed. This approach will lower maintenance costs while maintaining the safety of the propulsion system. The toolset is a modular program that is easily customizable by users. First, appropriate parametric damage accumulation models, which will be functions of engine variables, must be defined. The tool then optimizes the models to match the historical data by computing an effective-cycle metric that reduces the unexplained variability in component life due to each damage mode by accounting for the variability in operational severity. The damage increment due to operating conditions experienced during each flight is used to compute

  17. History of internal fixation (part 1): early developments with wires and plates before World War II.

    2017-06-01

    Though the date at which an orthopaedic implant was first used cannot be ascertained with any certainty, the fixation of bone fracture using an iron wire was reported for the first time in a French manuscript in 1775. The first techniques of operative fracture treatment were developed at the end of the 18th and in the beginning of the 19th centuries. The use of cerclage wires to fix fractures was the most frequent fixation at this time. The French Berenger-Feraud (1832-1900) had written the first book on internal fixation. However internal fixation of fractures could not become a practical method before Lister had ensured the safety of open reduction and internal fixation in the treatment of fractures. Lister is not only the father of asepsis; he also used metal wires to fix even closed fractures. The first internal fixation by means of a plate and screws was described by Carl Hansmann in 1858 in Hamburg. Nevertheless, Arbuthnot Lane (1892) and Albin Lambotte (1905) are considered to be the founders of this method, which was further developed by Sherman in the first part of the 20th century.

    The ultimate success of recent medical curriculum reforms is, in large part, dependent upon the faculty's ability to adopt and sustain new attitudes and behaviors. However, like many New Year's resolutions, sincere intent to change may be short lived and followed by a discouraging return to old behaviors. Failure to sustain the initial resolve to change can be misinterpreted as a lack of commitment to one's original goals and eventually lead to greater effort expended in rationalizing the status quo rather than changing it. The present article outlines how a transformative process that has proven to be effective in managing personal change, Questioning the Big Assumptions, was successfully used in an international faculty development program for medical educators to enhance individual personal satisfaction and professional effectiveness. This process systematically encouraged participants to explore and proactively address currently operative mechanisms that could stall their attempts to change at the professional level. The applications of the Big Assumptions process in faculty development helped individuals to recognize and subsequently utilize unchallenged and deep rooted personal beliefs to overcome unconscious resistance to change. This approach systematically led participants away from circular griping about what was not right in their current situation to identifying the actions that they needed to take to realize their individual goals. By thoughtful testing of personal Big Assumptions, participants designed behavioral changes that could be broadly supported and, most importantly, sustained.

  19. Integration of Error Compensation of Coordinate Measuring Machines into Feature Measurement: Part I—Model Development

    2016-01-01

    The development of an error compensation model for coordinate measuring machines (CMMs) and its integration into feature measurement is presented. CMMs are widespread and dependable instruments in industry and laboratories for dimensional measurement. From the tip probe sensor to the machine display, there is a complex transformation of probed point coordinates through the geometrical feature model that makes the assessment of accuracy and uncertainty measurement results difficult. Therefore, error compensation is not standardized, conversely to other simpler instruments. Detailed coordinate error compensation models are generally based on CMM as a rigid-body and it requires a detailed mapping of the CMM’s behavior. In this paper a new model type of error compensation is proposed. It evaluates the error from the vectorial composition of length error by axis and its integration into the geometrical measurement model. The non-explained variability by the model is incorporated into the uncertainty budget. Model parameters are analyzed and linked to the geometrical errors and uncertainty of CMM response. Next, the outstanding measurement models of flatness, angle, and roundness are developed. The proposed models are useful for measurement improvement with easy integration into CMM signal processing, in particular in industrial environments where built-in solutions are sought. A battery of implementation tests are presented in Part II, where the experimental endorsement of the model is included. PMID:27690052

    2011-02-01

    This series of reviews focuses on the most important neuromuscular function in many sport performances: the ability to generate maximal muscular power. Part 1, published in an earlier issue of Sports Medicine, focused on the factors that affect maximal power production while part 2 explores the practical application of these findings by reviewing the scientific literature relevant to the development of training programmes that most effectively enhance maximal power production. The ability to generate maximal power during complex motor skills is of paramount importance to successful athletic performance across many sports. A crucial issue faced by scientists and coaches is the development of effective and efficient training programmes that improve maximal power production in dynamic, multi-joint movements. Such training is referred to as 'power training' for the purposes of this review. Although further research is required in order to gain a deeper understanding of the optimal training techniques for maximizing power in complex, sports-specific movements and the precise mechanisms underlying adaptation, several key conclusions can be drawn from this review. First, a fundamental relationship exists between strength and power, which dictates that an individual cannot possess a high level of power without first being relatively strong. Thus, enhancing and maintaining maximal strength is essential when considering the long-term development of power. Second, consideration of movement pattern, load and velocity specificity is essential when designing power training programmes. Ballistic, plyometric and weightlifting exercises can be used effectively as primary exercises within a power training programme that enhances maximal power. The loads applied to these exercises will depend on the specific requirements of each particular sport and the type of movement being trained. The use of ballistic exercises with loads ranging from 0% to 50% of one-repetition maximum (1RM) and

    In part 1 of this series, we outlined the rationale behind the development of a centralized electronic database used to maintain nonsterile compounding formulation records in the Mission Health System, which is a union of several independent hospitals and satellite and regional pharmacies that form the cornerstone of advanced medical care in several areas of western North Carolina. Hospital providers in many healthcare systems require compounded formulations to meet the needs of their patients (in particular, pediatric patients). Before a centralized electronic compounding database was implemented in the Mission Health System, each satellite or regional pharmacy affiliated with that system had a specific set of formulation records, but no standardized format for those records existed. In this article, we describe the quality control, database platform selection, description, implementation, and execution of our intranet database system, which is designed to maintain, manage, and disseminate nonsterile compounding formulation records in the hospitals and affiliated pharmacies of the Mission Health System. The objectives of that project were to standardize nonsterile compounding formulation records, create a centralized computerized database that would increase healthcare staff members' access to formulation records, establish beyond-use dates based on published stability studies, improve quality control, reduce the potential for medication errors related to compounding medications, and (ultimately) improve patient safety.

    Solid catalysts containing metals, metal oxides or sulfides, which play a key role in the refining of petroleum to clean fuels and many other valuable products, become solid wastes after use. In many refineries, the spent catalysts discarded from hydroprocessing units form a major part of these solid wastes. Disposal of spent hydroprocessing catalysts requires compliance with stringent environmental regulations because of their hazardous nature and toxic chemicals content. Various options such as minimizing spent catalyst waste generation by regeneration and reuse, metals recovery, utilization to produce useful materials and treatment for safe disposal, could be considered to deal with the spent catalyst environmental problem. In this paper, information available in the literature on spent hydroprocessing catalyst waste reduction at source by using improved more active and more stable catalysts, regeneration, rejuvenation and reuse of deactivated catalysts in many cycles, and reusing in other processes are reviewed in detail with focus on recent developments. Available methods for recycling of spent hydroprocessing catalysts by using them as raw materials for the preparation of active new catalysts and many other valuable products are also reviewed.

    In this poster we describe the results of our project to design, manufacture, and measure a prototype starshade petal as part of the Technology Development for Exoplanet Missions program. An external occult is a satellite employing a large screen, or starshade,that flies in formation with a spaceborne telescope to provide the starlight suppression needed for detecting and characterizing exoplanets. Among the advantages of using an occulter are the broadband allowed for characterization and the removal of light for the observatory, greatly relaxing the requirements on the telescope and instrument. In this first two-year phase we focused on the key requirement of manufacturing a precision petal with the precise tolerances needed to meet the overall error budget. These tolerances are established by modeling the effect that various mechanical and thermal errors have on scatter in the telescope image plane and by suballocating the allowable contrast degradation between these error sources. We show the results of this analysis and a representative error budget. We also present the final manufactured occulter petal and the metrology on its shape that demonstrates it meets requirements. We show that a space occulter built of petals with the same measured shape would achieve better than 1e-9 contrast. We also show our progress in building and testing sample edges with the sharp radius of curvature needed for limiting solar glint. Finally, we describe our plans for the second TDEM phase.

    The authors have developed a new method of constructing high density bentonite barriers by means of a wet spraying method. Using this method, backfill material can be placed in narrow upper and side parts in a low-level radioactive waste disposal facility. Using a new supplying machine for bentonite, spraying tests were conducted to investigate the conditions during construction. On the basis of the test results, the various parameters for the spraying method were investigated. The test results are summarized as follows: 1. The new machine supplied about twice the weight of material supplied by a screw conveyor. A dry density of spraying bentonite 0.05 Mg/m 3 higher than that of a screw conveyor with the same water content could be achieved. 2. The dry density of sprayed bentonite at a boundary with concrete was the same as that at the center of the cross section. 3. The variation in densities of bentonite sprayed in the vertical downward and horizontal directions was small. Also, density reduction due to rebound during spraying was not seen. 4. Bentonite controlled by water content could be sprayed smoothly in the horizontal direction by a small machine. Also rebound could be collected by a machine conveying air. (author)

The authors also provide a review of all previous IGCT related publications. Methods: The authors designed and implemented a gantry-based 32-source IGCT scanner with 22 cm field-of-view, 16 cm z-coverage, 1 s rotation time, 1.09 × 1.024 mm detector cell size, as low as 0.4 × 0.8 mm focal spot size and 80–140 kVp x-ray source voltage. The system is built using commercially available CT components and a custom made distributed x-ray source. The authors developed dedicated controls, calibrations, and reconstruction algorithms and evaluated the system performance using phantoms and small animals. Results: The authors performed IGCT system experiments and demonstrated tube current up to 125 mA with up to 32 focal spots. The authors measured a spatial resolution of 13 lp/cm at 5% cutoff. The scatter-to-primary ratio is estimated 62% for a 32 cm water phantom at 140 kVp. The authors scanned several phantoms and small animals. The initial images have relatively high noise due to the low x-ray flux levels but minimal artifacts. Conclusions: IGCT has unique benefits in terms of dose-efficiency and cone-beam artifacts, but comes with challenges in terms of scattered radiation and x-ray flux limits. To the authors’ knowledge, their prototype is the first gantry-based IGCT scanner. The authors summarized the design and implementation of the scanner and the authors presented

  18. Two-Year Institution Part-Time Nurse Faculty Experiences During Role Transition and Identity Development: A Phenomenological Study.

    Science.gov (United States)

    Owens, Rhoda A

    This study explored two-year institution part-time nurse faculty's perceptions of their experiences during their role transitions from nurses in clinical practice to part-time clinical instructors. Part-time nurse faculty enter academia as expert clinicians, but most have little or no training in the pedagogy of effective student learning. A phenomenological study was used to explore the faculty role transition experiences. Findings support the proposition that six participants transitioned from their expert clinician to instructor identities; however, two continue in the process. Critical to this process are relationships with individuals in their environments, past and present experiences, the incentive to learn to be better instructors, and the importance of support and training. A model emerged, Process of Role Transition and Professional Identity Formation for Part-Time Clinical Instructors at Two-Year Institutions, that is potentially useful for administrators in developing individualized orientation and professional development programs.

    Countercurrent chromatography (CCC) and centrifugal partition chromatography (CPC) are support free liquid-liquid chromatography techniques sharing the same basic principles and features. Method transfer has previously been demonstrated for both techniques but never from one to another. This study aimed to show such a feasibility using fractionation of Schinus terebinthifolius berries dichloromethane extract as a case study. Heptane - ethyl acetate - methanol -water (6:1:6:1, v/v/v/v) was used as solvent system with masticadienonic and 3β-masticadienolic acids as target compounds. The optimized separation methodology previously described in Part I and II, was scaled up from an analytical hydrodynamic CCC column (17.4mL) to preparative hydrostatic CPC instruments (250mL and 303mL) as a part of method development. Flow-rate and sample loading were further optimized on CPC. Mobile phase linear velocity is suggested as a transfer invariant parameter if the CPC column contains sufficient number of partition cells. Copyright © 2017 Elsevier B.V. All rights reserved.

  10. NEW DEVELOPMENTS IN LOW TEMPERATURE PHYSICS : Part of the Activity Report to the IUPAP General Assembly

    Science.gov (United States)

    Hallock, Bob; Paalanen, Mikko

    2009-03-01

    Below you find part of the Activity Report to the IUPAP General Assembly, October 2008, by the present and previous Chairmen of C5. It provides an overview of the most important and recent developments in low temperature physics, much in line with the program of LT25. For the field of experimental low temperature physics, the ability to conduct research has been damaged by the dramatic increase in the price of liquid helium. In the United States for example, the price of liquid helium has approximately doubled over the past two years. This has led to a reduction in activity in many laboratories as the funding agencies have not quickly increased support in proportion. The increase in price of liquid helium has accelerated interest in the development and use of alternative cooling systems. In particular, pulse tube coolers are now available that will allow cryostats with modest cooling needs to operate dilution refrigerators without the need for repeated refills of liquid helium from external supply sources. Solid helium research has seen a dramatic resurgence. Torsional oscillator experiments have been interpreted to show that solid helium may undergo a transition to a state in which some of the atoms in the container do not follow the motion of the container, e.g. may be 'supersolid'. The observation is robust, but the interpretation is controversial. The shear modulus of solid helium undergoes a similar signature with respect to temperature. Experiments that should be expected to cause helium to flow give conflicting results. Theory predicts that a perfect solid cannot show supersolid behavior, but novel superfluid-like behavior should be seen in various defects that can exist in the solid, and vorticity may play a significant role. And, recently there have been reports of unusual mass decoupling in films of pure 4He on graphite surfaces as well as 3He-4He mixture films on solid hydrogen surfaces. These may be other examples of unusual superfluid-like behavior

  12. Development of an internet version of the Lidcombe Program of early stuttering intervention: A trial of Part 1.

    2018-04-01

    There is evidence that access to treatment for early stuttering is not available for all who need it. An internet version of the Lidcombe Program for early stuttering (Internet-LP) has been developed to deal with this shortfall. The LP is suitable for such development because it is delivered by parents in the child's everyday environment, with training by a speech-language pathologist. A Phase I trial of Internet-LP Part 1, comprising parent training, is reported here. Eight parents of pre-schoolers who stutter were recruited and six completed the trial. Post-trial assessment indicated that the parents scored well for identifying and measuring stuttering and for knowledge about conducting practice sessions, including how to present verbal contingencies during practice sessions. The results prompted minor adjustments to Part 1 and guided the construction of Part 2, which instructs parents during the remainder of the treatment process.

  13. National preceptor development program (PDP) prototype. The third of a 3-part series.

    Cox, Craig D; Mulherin, Katrina; Walter, Sheila

    2018-03-01

    Preceptor development is critical to successful delivery of experiential learning. Although many preceptor development programs exist, a more individualized approach to training is needed. To accomplish this a national preceptor development program should be considered based on the continuing professional development model. A detailed prototype for this program has been described. In this final installment of the series, the twelve evidence-based recommendations from the first installment were utilized to construct a prototype for a preceptor development program. Over a three-month period, investigators experimented with different designs and models before approving the final prototype. The prototype took the form of an electronic learning platform. Several categories were integral to the design and included sections entitled preceptor spotlight, mentorship, global outreach, choose your own adventure, continuing professional development, feedback, virtual online community, highlights/advertisements, what's new, competency assessment, and frequently asked questions. A graphic was developed to depict the process by which a preceptor would navigate through the web-based learning platform. The authors purposefully maintained a creative and unlimited vision for preceptor development. This conceptual model is intended to spark discussion and augment, refine, or develop entirely innovative ideas to meet preceptor needs. Development of a preceptor development platform could foster improved competency performance, enhanced interest in learning, and promote continuing professional development. With a greater focus on experiential education in pharmacy, the need for a national preceptor development resource is only expected to increase. Copyright © 2017 Elsevier Inc. All rights reserved.

    NONE

    2003-03-15

    This first part of a two-part report for the International Energy Agency (IEA) made by Task 9 of the Photovoltaic Power Systems (PVPS) programme takes a look at the implementation of Solar Home systems in developing countries. The objective of Task 9 is to increase the successful deployment of PV systems in developing countries. This summary outlines various models for the implementation of small domestic photovoltaic (PV) systems (Solar Home Systems, SHS) in developing countries. Part 1 of this two-part document discusses three generic models. The second, separate part of the document provides a number of examples demonstrating the models described. This report focuses on the implementation of SHS. However, a considerable amount of the PV market in developing countries is stated as consisting of large systems providing electricity for social services, such as light for schools, mosques, churches, communal centres, refrigeration for health centres and drinking water for communities. It is noted that there are considerable differences between the 'social market' and the 'private market' for SHS. The 'social market' generally consists of large systems but fewer in number. The guide does not cover the detailed technical aspects of a Solar Home System or the issue of recycling old batteries.

  2. Development of ITER PRM and standard parts catalogues in CATIA V5 for tritium-containing systems and components

    2006-01-01

    CATIA V5 is a software chosen to perform the design and integration within ITER of both systems: fluid and mechanical systems. The broad range of applications provides the ability to develop the design process from the functional 2D design (P and ID) to the 3D plant layouts and detailed design. The 2D symbols for the equipment and piping components were developed in accordance with EN ISO 10628 standard, ISO 3511 (part I, II and IV) standard and DIN 28401 standard and considering the classification and settings done by FZK-team in the PRM-FZK-TLK in order to ensure compliance with the established design standards. These symbols were inserted in 2D catalogues linked with the main catalogue installed in PRM-FZK-TLK on CATIA SERVER at TLK-FZK and intensively tested in Piping and Instrumentation Diagrams. The 3D part for the equipment, instruments and piping components was developed according to the specifications, industrial conventions, terminology and literature available in library, internet and practice. All parts were parametrically built in order to allow the designer to modify the part geometry according to the design. The 3D parts were typed in accordance with IKARUS-Project Instructions by FZK team, inserted in 3D test catalogues and tested in Equipment and Systems workbench. The elements of P and ID, pipes, piping parts, instruments and equipment carry attribute information such as fluid type, pressure rating, insulation or material. The list of attributes is defined in the PRM and consists of the standard industrial attributes implemented by default in CATIA V5 and project specific attributes defined by Project Administration. 2D logical design and 3D Piping models are logically related through the common functions definition in the PRM. The task, TW5-TTFD-TPI-51, was performed collaboratively by MEdC/ICIT and FZK/TLK. (authors)

  4. New Developments in Mass Spectrometry for Group-Type Analysis of Petroleum Cuts (First Part

    Directory of Open Access Journals (Sweden)

    Fafet A.

    1999-07-01

    Full Text Available Characterization of petroleum cuts constitutes a necessary stage to perfect understanding of the reaction mechanisms and to the description of the kinetics of certain refining processes such as hydrotreating or catalytic cracking. Mass spectrometry (MS, thanks to group-type quantitative analysis methods, enables to access detailed description of complex hydrocarbon mixtures such as middle distillates or heavy cuts such as vacuum distillates. But these methods are also subject to some drawbacks and we shall expose, thereunder, two examples of improvements. In a first part, the accuracy of MS quantification of thiophenic sulphured compounds in middle distillates is studied by intertechnique comparison with the results obtained by gas phase chromatography coupled to sulphur-specific detection by chemiluminescence (GC/SCD. Improving on the MS method is suggested. In the second part, a new system for introducing the sample in the spectrometer source, dedicated to group-type analysis of heavy cuts is described. Its validation, by comparison of the MS results to those of liquid chromatography (LC as well as its performances, is exposed.

    2017-07-01

    In 2004, Murray et al. reviewed methodological developments in the design and analysis of group-randomized trials (GRTs). We have updated that review with developments in analysis of the past 13 years, with a companion article to focus on developments in design. We discuss developments in the topics of the earlier review (e.g., methods for parallel-arm GRTs, individually randomized group-treatment trials, and missing data) and in new topics, including methods to account for multiple-level clustering and alternative estimation methods (e.g., augmented generalized estimating equations, targeted maximum likelihood, and quadratic inference functions). In addition, we describe developments in analysis of alternative group designs (including stepped-wedge GRTs, network-randomized trials, and pseudocluster randomized trials), which require clustering to be accounted for in their design and analysis.

    After neutron exposure and chemical etching in advance, latent tracks of recoil nucleon develop into pits on CR39 surface. During electrochemical etching, plastic zone is formed at top of pits. Some pits develop into tree cracks in the initial stage of plastic zone development. Physical and mathematical model of crack and plastic zone is proposed; parameter of development free path of plastic zone is presented. Based on integration of elementary theories the stress analysis is build up; based on analyses of measured parameters, a set of common relations between parameters is obtained. Integrate parameter analysis and stress analysis, depth of plastic zone development, law and phenomenon in experimental data can be interpreted completely

    The current research recognises the concept of innovation as the main driver for organisational growth and profitability. The companies seek to develop new ways to engage consumers and customers into co - creation value through the product design, development and distribution processes. However the main concern is manifested for new and creative ways of customization products based on consumers’ requirements and needs. Thus the need for innovative virtual instruments arose as the demand from social communities for personalised products or services increased. Basically companies should develop own innovative platforms, where consumers can participate, with ideas, concepts or other relevant contributions, and interact with designers or engineers for product development. This paper aims to present the most important features of platform development within BMW Group as a concept and as innovative instrument. From this point of view it is important to enhance past experiences of the company in the field of co - creation projects. There will be highlighted the dual consumers’ character as co - creator and co - evaluator based on their involvement in the proposed and developed projects and platform structure. The significant impact on platform functioning it has the diversity of company's concerns for Research & Development and innovation activities. From this point of view there will be assessed the platform structure, the main proposed themes and the evaluation process. The main outcome is to highlight the significance of platform development as innovative tool for consumers’ communities’ enhancement. Based on the analysis of “BMW Co-Creation Lab”, there will be revealed the main consumers concerns in terms of safety, comfort and appearance of the products. Thus it is important to understand the evaluation process of gathered ideas and intellectual property policy. The importance of platform development and implementation will be highlighted by company

    In 2012, the Experimental Products Development Team (EPDT) was formed within NASA's Short-term Prediction Research and Transition (SPoRT) Center to create training for development of plug-ins to extend the National Weather Service (NWS) Advanced Weather Interactive Processing System (AWIPS) version 2. The broader atmospheric science community had a need for AWIPS II development training being created at SPoRT and EPDT was expanded to include other groups who were looking for training. Since the expansion of the group occurred, EPDT has provided AWIPS II development training to over thirty participants spanning a wide variety of groups such as NWS Systems Engineering Center, NWS Meteorological Development Laboratory, and several NOAA Cooperative Institutes. Participants within EPDT solidify their learning experience through hands-on learning and by participating in a "code-sprint" in which they troubleshoot existing and develop plug-ins. The hands-on learning workshop is instructor lead with participants completing exercises within the AWIPS II Development Environment. During the code sprints EPDT groups work on projects important to the community and have worked on various plug-ins such as an RGB image recipe creation tool, and an mPing (crowd sourced precipitation type reporting system) ingest and display. EPDT has developed a well-defined training regime which prepares participants to fully develop plug-ins for the extendible AWIPS II architecture from ingest to the display of new data. SPoRT has hosted 2 learning workshops and 1 code sprint over the last two years, and continues to build and shape the EPDT group based on feedback from previous workshops. The presentation will provide an overview of EPDT current and future activities, and best practices developed within EPDT.

    Full Text Available The city grows from the seed to the core. The historical core is the central part with historical significance, around which other programmes are aligned. Possibilities define growth and density of a city, but this is the source of problems. Growth is influenced by activities moving, changes in social and political life, but also important elements of culture and sports. Visibility, sometimes termed beauty, is only the external layer of the interior, the essence itself. A functioning village cannot be ugly. Fire, the fireplace, house, home, village, city (survival, needs and possibilities are closer to the circle and theory, than can be expected. Growth of architecture from the detail to spatial planning is the fruit of human balancing only in detail. Cities grow according to their own logic. The role of professions is therefore limited only to the establishment of strategies and controlling their growth. Things are much simpler, than we can imagine.

    2014-01-01

    This is the second half of a two paper series covering aspects of the no fault found (NFF) phenomenon, which is highly challenging and is becoming even more important due to increasing complexity and criticality of technical systems. Part 1 introduced the fundamental concept of unknown failures from an organizational, behavioral and cultural stand point. It also reported an industrial outlook to the problem, recent procedural standards, whilst discussing the financial implications and safety concerns. In this issue, the authors examine the technical aspects, reviewing the common causes of NFF failures in electronic, software and mechanical systems. This is followed by a survey on technological techniques actively being used to reduce the consequence of such instances. After discussing improvements in testability, the article identifies gaps in literature and points out the core areas that should be focused in the future. Special attention is paid to the recent trends on knowledge sharing and troubleshooting tools; with potential research on technical diagnosis being enumerated

    As part of the effort to downsize its uranium processing facilities, the Y-12 Plant has supported an investigation to identify extraction solvents that would both work efficiently in centrifugal contactors and be disposed of easily. Various organic ethers, hydroxy ethers, ether ketones, acids, amides, and diketones were studied for their ability to extract uranyl nitrate from aqueous solutions. Although many of these solvents were obtained commercially, others had to be synthesized in-house. The authors found a large range of extraction coefficients for these solvents. Because of steric hindrance or some other factor, certain ethers performed poorly. On the other hand, various mono- and diethers of tetrahydrofurfuryl alcohol exhibited excellent extraction and stripping coefficients for uranyl nitrate, justifying purchase of a pilot plant batch of one of this family of solvents. Likewise, the authors determined the extraction coefficient for one of the two amides synthesized in-house to be quite high

    1988-01-01

    The head of a hydra is composed of two parts, a domed hypostome with a mouth at the top and a ring of tentacles below. When animals are decapitated a new head regenerates. During the process of regeneration the apical tip passes through a transient stage in which it exhibits tentacle......-like characteristics before becoming a hypostome. This was determined from markers which appeared before morphogenesis took place. The first was a monoclonal antibody, TS-19, that specifically binds to the ectodermal epithelial cells of the tentacles. The second was an antiserum against the peptide Arg......-Phe-amide (RFamide), which in the head of hydra is specific to the sensory cells of the hypostomal apex and the ganglion cells of the lower hypostome and tentacles. The TS-19 expression and the ganglion cells with RFamide-like immunoreactivity (RLI) arose first at the apex and spread radially. Once the tentacles...

    The Sao Paulo - Brasilia Pipeline (OSBRA) is a highly automated pipeline using a SCADA system which operates from a control room. A new quality management system standard was established for transportation and storage operations. The products had to be sampled on an automatic basis. This paper reports the development of an automatic sampling system (ASS) in accordance with the new quality control standard. The prototype was developed to be implemented through a human-machine interface (HMI) from the control room SCADA screens. A technical cooperation agreement(TCA) was drawn up for development of this new ASS product. The TCA was a joint cooperation between the Holding, the Operator and the cooperators. The prototype will be on-field tested at Senador Canedo tank farm to SPEC requirements. The current performance of the ASS establishes reasonable expectations for further successful development.

    Ure, James; Chen, Haofeng; Tipping, David

    2014-01-01

    A number of direct methods based upon the Linear Matching Method (LMM) framework have been developed to address structural integrity issues for components subjected to cyclic thermal and mechanical load conditions. This paper presents a new integrated structural analysis tool using the LMM framework for the assessment of load carrying capacity, shakedown limit, ratchet limit and steady state cyclic response of structures. First, the development of the LMM for the evaluation of design limits in plasticity is introduced. Second, preliminary considerations for the development of the LMM into a tool which can be used on a regular basis by engineers are discussed. After the re-structuring of the LMM subroutines for multiple central processing unit (CPU) solution, the LMM software tool for the assessment of design limits in plasticity is implemented by developing an Abaqus CAE plug-in with graphical user interfaces. Further demonstration of this new LMM analysis tool including practical application and verification is presented in an accompanying paper. - Highlights: • A new structural analysis tool using the Linear Matching Method (LMM) is developed. • The software tool is able to evaluate the design limits in plasticity. • Able to assess limit load, shakedown, ratchet limit and steady state cyclic response. • Re-structuring of the LMM subroutines for multiple CPU solution is conducted. • The software tool is implemented by developing an Abaqus CAE plug-in with GUI

    Smith, Tony; Lewis, Sarah

    2003-01-01

    This is the second of two consecutive papers on the topic of radiographer role development. In the first paper, the rationale for role development was put forward and potential pathways for role extension were described and discussed. In this paper, a multi-tiered model of career structure, recently piloted in the United Kingdom, is firstly examined. A similar model, incorporating assistant practitioners, registered practitioners, advanced practitioners and consultant practitioners could be adapted to improve career pathways for Australian radiographers and accommodate future role development opportunities. However, for real benefits to all stakeholders, it would be important that the lower end of the career ladder is not altered without also redeveloping the upper end. The medical imaging professions should strongly resist any redevelopment of the former without the latter. In order for role development to progress successfully a coordinated approach and the involvement of the professional bodies, the educational institutions and government(s), would be essential. The potential contributions of the various stakeholder organisations are discussed and, as a means of promoting communication on the issues, the formation of a Special Interest Group in Radiographer Role Development (SIGRRD) is recommended. SIGRRI) would provide a mechanism for planning, monitoring and evaluating role development initiatives to ensure optimum outcomes Copyright (2003) Australian Institute of Radiography

    2004-01-01

    The process development test program for production of Slightly Enriched Uranium (SEU) dioxide powder had started with 100 g Low Enriched Uranium (LEU) dioxide powder samples obtained from different suppliers. Encouraging results obtained in the initial test program established a basis for working with 9.5 kg LEU powder samples and production of larger quantities of SEU powder for characterization to meet the target quality and ensuring development of process design criteria for the commercial scale plant design. Similarly, the process development test program for production of Blended Dysprosium and Uranium (BDU) oxide powders was initiated using different Dy 2 O 3 powder samples from different suppliers. The variability of the quality of Dy 2 O 3 powder samples received from different suppliers resulted in substantial investigation in characterization of Dy 2 O 3 powders. The test program for both products required forming a cross-functional project team from several departments within Cameco with the focus of the development work to be carried out at the Cameco Technology Development. Many aspects of developing two new products were addressed. These included developing design criteria for preparation of SEU and BDU powders for a Demonstration Irradiation (DI) program and commercial scale plant, Quality Assurance program (including specifications for SEU and BDU powder products, SEU and BDU scraps, Cameco Quality Specifications for purchasing LEU and Dy 2 O 3 powders, and Inspection and Test Plan for SEU and BDU powder production), accurate uranium accountability, enhanced safety requirements, bench and laboratory test safety and operability manuals and procedures for analysis.

    1978-12-04

    The objective of this project is the development of a preliminary design for a full-sized, closed cycle, ammonia power system module for the 100 MWe OTEC demonstration plant. In turn, this demonstration plant is to demonstrate, by 1984, the operation and performance of an Ocean Thermal Power Plant having sufficiently advanced heat exchanger design to project economic viability for commercial utilization in the late 1980's and beyond. Included in this power system development are the preliminary designs for a proof-of-concept pilot plant and test article heat exchangers which are scaled in such a manner as to support a logically sequential, relatively low-cost development of the full-scale power system module. The conceptual designs are presented for the demonstration plant power module, the proof-of-concept pilot plant, and for a pair of test article heat exchangers. Costs associated with the design, development, fabrication, checkout, delivery, installation, and operation are included. The accompanying design and producibilty studies on the full-scale power system module project the performance/economics for the commercial plant. This section of the report contains appendices on the developed computer models, water system dynamic studies, miscellaneous performance analysis, materials and processes, detailed equipment lists, turbine design studies, tube cleaner design, ammonia leak detection, and heat exchanger design supporting data.

  18. Contemporary Views on Development of Excess Body Weight and Obesity in Children. Part I

    Directory of Open Access Journals (Sweden)

    M. V. Khodzhiyeva

    2015-01-01

    Full Text Available Obesity is one of the most widespread chronic diseases around the world and may be considered a non-infectious epidemic. Virtually everywhere around the world the number of obese children doubles every three decades. Increase in the number of children with obesity and excess body weight is observed in Russia as well. Despite the statement that the main cause of obesity is energy expenditure/consumption imbalance, numerous data obtained in recent years indicate early factors of obesity forming, probably, during the period of intrauterine development and/or infancy and early childhood. The most active growth and maximum plasticity of metabolic processes is observed within 1,000 post-conceptual days, which cover the period of intrauterine development and the first 2 years of a child’s life. The number and quality of nutrients received during that period considerably affect cell differentiation and organ development by means of gene expression, determine the nature of metabolism and affect health condition throughout the whole subsequent life. Given significance of the issue of excess body weight in children and adults, we analyzed the current situation, examined 652 younger Moscow schoolchildren and determined parameters of their physical development. We analyzed anamnestic data, profoundly examined children with excess body weight and obesity and formulated diets for them. This article presents the first stage of our work and a literature review.

    Canada has had a long and successful record of hydroelectric power development since the first hydraulic generators were installed at Chaudiere Falls near Ottawa in 1881. Canadian hydro engineers have demonstrated their ability to develop and manage higher voltages, longer transmission networks, larger projects, remote sites, and undersea cable technology. Canada has earned a reputation for excellence in the hydro industry and is successful at exporting its expertise to develop hydro resources in the international market. A prominent example is provided by the Three Gorges Project in China, for which the Chinese Ministry of Energy searched for the best foreign engineers to prepare a feasibility report. A Canadian team that integrated the expertise of hydro consultants, utilities, and major equipment suppliers was chosen to prepare the report, winning over teams from the USA, Brazil, and Europe. Success in this initiative is attributed to Canada's ability to demonstrate the favorable application of new technology at James Bay. Domestic hydro projects are thus seen as crucial in efforts to expand into international markets. However, Canada's new completed hydro capacity has fallen dramatically since 1986, and Canadian hydro contractors have tended to remain domestic operators with little incentive to enter foreign markets. By having the foresight to begin new hydro developments now, Canada would benefit from increased employment and orders for equipment, and would ensure a continuing base of technical expertise and innovation in the electrical industry. 2 figs

    Full Text Available Implementation of the concept of sustainable exploitation of medicinal plant resources facilitates the development of tourism offering and the related activities that would enhance the development of rural areas in this region. When managed in a sustainable manner, tourism can bring many advantages to protected areas, tourism industry and a local community. By using high-resolution satellite images and application of GIS technology, a method is developed for monitoring periodic changes in eco-systems. The collected data enable design of models that incorporate in themselves dynamics of changes taking place in natural ecosystems. By means of periodic imaging of characteristic areas, the spatial representation of eco-systems will be monitored, along with the changes in their composition and structure, which may seriously endanger the development of tourism potential in the region. The integral approach to the management of medicinal herb resources in the region of Mt. Stara Planina, based on the results of this study, necessitates the integration of these results with the results of the studies investigating views and needs of the local population, whose quality of life depends on sustainability of the process of collection and valorization of this resource.

    2017-03-01

    Full Text Available Absolute pitch is defined as the ability to identify the pitch class of a certain given sound without the aid of an external reference pitch (Takeuchi & Hulse, 1993; Deutsch, 2002. The incidence of absolute pitch is extremely rare among the general population, respectively 1 in 10.000 people and it depends on testing conditions such as the number of identified sounds, pitch Chroma, pitch height, timbre, register or requested reaction time, and also on subjects musical training commencing and Eastern-Asian origins. The way absolute pitch develops is described by three models: the tone language theory, the early training theory and the genetic theory. The early training theory states that absolute pitch appears due to the beginning of musical lessons during a critical development period situated before the age of 6. The educational implications of this theory are revealed in the principles and activities of Yamaha Music School which employs didactic strategies that naturally develop absolute pitch. Yamaha Music School is the largest private music education system from Japan, established by Torakusu Yamaha in 1954. Up to this day it has extended in 40 countries from Europe, Asia and the American continents, as it has about 710 million students and 30.000 teachers. The present study aims to illustrate a detailed analysis of the way the learning experiences offered by Yamaha School lead to the development of absolute pitch.

    Biba, Nikolay; Alimov, Artem; Shitikov, Andrey; Stebunov, Sergei

    2018-05-01

    The demand for high performance and energy efficient transportation systems have boosted interest in lightweight design solutions. To achieve maximum weight reductions, it is not enough just to replace steel parts by their aluminium analogues, but it is necessary to change the entire concept of vehicle design. In this case we must develop methods for manufacturing a variety of critical parts with unusual and difficult to produce shapes. The mechanical properties of the material in these parts must also be optimised and tightly controlled to provide the best distribution within the part volume. The only way to achieve these goals is to implement technology development methods based on simulation of the entire manufacturing chain from preparing a billet through the forming operations and heat treatment of the product. The paper presents an approach to such technology development. The simulation of the technological chain starts with extruding a round billet. Depending on the extrusion process parameters, the billet can have different levels of material workout and variation of grain size throughout the volume. After extrusion, the billet gets formed into the required shape in a forging process. The main requirements at this stage are to get the near net shape of the product without defects and to provide proper configuration of grain flow that strengthens the product in the most critical direction. Then the product undergoes solution treatment, quenching and ageing. The simulation of all these stages are performed by QForm FEM code that provides thermo-mechanical coupled deformation of the material during extrusion and forging. To provide microstructure and heat treatment simulation, special subroutines has been developed by the authors. The proposed approach is illustrated by an industrial case study.

    This paper presents an analytical technique for determining peak, offpeak and midpeak hours tariffs for various durations of these three periods. The technique considers the existing flat rate tariff, an hourly generation scenario of a utility on an average yearly demand day, the weighted average life time, annutised capital cost and fuel cost of base and peak load plants, and a break even point condition in the utility's revenue. The developed tariff has been applied to 30 representative industrial consumers served by the Bangladesh Power Development Board (BPDB) to estimate the minimum possible shift in consumption pattern and hence corresponding reduction in peak generation capacity requirements as well as peak time load shedding by BPDB.

    Full Text Available Despite quite similar conditions (natural resources for electricity production from renewable energy sources (RES-E in three Baltic States (Estonia, Latvia and Lithuania, significant differences exist in these countries as to the RES-E production volume. In Latvia this volume is the highest, while in Estonia and Lithuania it is half as high. One of the factors that determine the RES-E production volumes is support policies, which in the Baltic States are different. The main objective of this work was to analyze and compare these support policies. The results have shown that for rapid RES-E development the most effective policy is to be market-oriented (as in Estonia, whereas for more stable development such policy should be producer-oriented (as in Lithuania.

    A review of four major hydro consultants across Canada illustrates how the private sector has become an important resource for export of Canadian goods and services. The major utilities have contributed in operations and training and have acted as catalysts in this process. An overview is presented of the history and export activities of four consultants: Monenco, Acres, SNC, and Klohn-Crippen. The linkage between domestic experience and expansion into foreign markets in hydro resource development is apparent. Domestic projects have fallen into a severe decline due to the market; it is suggested that cyclical markets might be avoided by constructing capacity in advance. A tally is provided of current Canadian projects, which represent a substantial economic potential for sustainable, renewable hydroelectric resource development. 1 fig

    2009-09-01

    Following the establishment of Gastroenterology and Hepatology Fellowship Programs in 1987, significant developments in research and health care delivery have been achieved. The number of published articles has increased significantly and now more than 10 approved research centers are involved in several longitudinal and population based studies in GI epidemiology, viral hepatitis and GI oncology around the country. Before 1987 less than 50 gastroenterologists were working in the country, but now more than 300 gastroenterologists are involved in public and private health care delivery systems. Advanced diagnostic and therapeutic endoscopic procedures and complex surgical procedures such as liver transplantation are a routine now. These achievements are indicative of hard work and determination of dedicated physicians after the Islamic Revolution, and the support of governmental and non-governmental sectors. The future prospect of development in the discipline of gastroenterology and hepatology in Iran seems to be very encouraging.

    Priority #3 of the Canadian Experiential Education Project for Pharmacy provided evidence-based guidance for the design and implementation of a national approach to preceptor development. In this first article (of three), findings from the project and recommendations to achieve a high-quality preceptor development program (PDP) are presented. A multi-method approach including detailed semi-structured interviews, classic literature review, and advisory committee feedback was employed. The research team performed an integrated analysis of all data to achieve the objectives of Priority #3. Fifteen formal interviews, 167 articles and two stakeholder meetings informed findings. Experiential Education programs exhibited commonality in content and usually delivered programs online using modules or live lectures. Not all programs required preceptor education despite it being mandated by academic accreditors. Academics' perceptions varied regarding pharmacists' baseline knowledge, skills and attitudes prior to engaging in the preceptor role. A national approach to a PDP was desired if jurisdictional content was accommodated. Copious interprofessional literature of generally fair quality did not identify superior preceptor development approaches although there were numerous descriptions of interventions. Only 29 articles measured educational outcomes. Outcomes included satisfaction rates, self-efficacy and perceived knowledge, skill retention, skill implementation and participation rates. Twelve recommendations were identified to guide successful development of a national PDP. In the absence of good evidence, adult educational theory provided a basis for an effective PDP. Findings from Priority #3 may be relevant not only to pharmacy in Canada but other health professions and counterparts in other western nations with similar approaches to professional education.

    The High-Uranium-Loaded U 3 O 8 -Al Fuel Element Development Program supports Argonne National Laboratory efforts to develop high-uranium-density research and test reactor fuel to accommodate use of low-uranium enrichment. The goal is to fuel most research and test reactors with uranium of less than 20% enrichment for the purpose of lowering the potential for diversion of highly-enriched material for nonpeaceful usages. The specific objective of the program is to develop the technological and engineering data base for U 3 O 8 -Al plate-type fuel elements of maximal uranium content to the point of vendor qualification for full scale fabrication on a production basis. A program and management plan that details the organization, supporting objectives, schedule, and budget is in place and preparation for fuel and irradiation studies is under way. The current programming envisions a program of about four years duration for an estimated cost of about two million dollars. During the decades of the fifties and sixties, developments at Oak Ridge National Laboratory led to the use of U 3 O 8 -Al plate-type fuel elements in the High Flux Isotope Reactor, Oak Ridge Research Reactor, Puerto Rico Nuclear Center Reactor, and the High Flux Beam Reactor. Most of the developmental information however applies only up to a uranium concentration of about 55 wt % (about 35 vol % U 3 O 8 ). The technical issues that must be addressed to further increase the uranium loading beyond 55 wt % U involve plate fabrication phenomena of voids and dogboning, fuel behavior under long irradiation, and potential for the thermite reaction between U 3 O 8 and aluminum

    The present work aims at constructing the ideal scaffold matrix of which the physico-chemical properties can be altered according to the targeted tissue regeneration application. Ideally, this scaffold should resemble the natural extracellular matrix (ECM) as close as possible both in terms of chemical composition and mechanical properties. Therefore, hydrogel films were developed consisting of methacrylamide-modified gelatin and starch-pentenoate building blocks because the ECM can be considered as a crosslinked hydrogel network consisting of both polysaccharides and structural, signaling and cell-adhesive proteins. For the gelatin hydrogels, three different substitution degrees were evaluated including 31%, 72% and 95%. A substitution degree of 32% was applied for the starch-pentenoate building block. Pure gelatin hydrogels films as well as interpenetrating networks with gelatin and starch were developed. Subsequently, these films were characterized using gel fraction and swelling experiments, high resolution-magic angle spinning (1)H NMR spectroscopy, rheology, infrared mapping and atomic force microscopy. The results indicate that both the mechanical properties and the swelling extent of the developed hydrogel films can be controlled by varying the chemical composition and the degree of substitution of the methacrylamide-modified gelatin applied. The storage moduli of the developed materials ranged between 14 and 63kPa. Phase separation was observed for the IPNs for which separated starch domains could be distinguished located in the surrounding gelatin matrix. Furthermore, we evaluated the affinity of aggrecan for gelatin by atomic force microscopy and radiolabeling experiments. We found that aggrecan can be applied as a bioactive coating for gelatin hydrogels by a straightforward physisorption procedure. Thus, we achieved distinct fine-tuning of the physico-chemical properties of these hydrogels which render them promising candidates for tissue engineering

    Full Text Available Modal share is an important component in developing sustainable transport within a city. In recent years, many cities have set modal share targets for balanced and sustainable transport modes: 30% of public transport and 30% of non-motorized (cycling and walking modes. Gdansk strategic documents have set similar goals with some actions already taken towards those goals. The cycle network is increasing popular. Gdansk’s cycling infrastructure is more developed than that in other Polish cities. Promotional actions are undertaken each year. Despite that, the share of cycling in the modal split still remains at the low level of 1-3%. The article analyses the case study of Gdansk’s cycling policy and its results. The article summarizes the modal share targets set in Gdansk’s strategic documents, describes the development of its cycle network and promotional campaigns, and presents the volume of bicycle traffic and its share in the city’s modal split. Finally, the article aims to identify the causes behind the low percentage of bicyclists in Gdansk.

    Full Text Available A single factor (variety strict field experiment was carried out in 1999-2000 at the experimental station of the Department of Plant Production, Agricultural University of Krakow located at Prusy near Cracow to study the changes in selected macro-and microelement concentrations in the top parts of linseed and the uptake of these elements during vegetation at the characteristic phases of development, including also the plant parts, i.e. leaves, stems, seeds and straw. On the basis of obtained results it was demonstrated that microelement contents in the linseed top parts changed considerably with the plant growth. The levels of Cr, Zn,Cd, Fe and Mn were highest at budding, while Cr, Pb, Fe and Mn levels were lowest at full maturity phase. Linseed grown in the area unpolluted with trace elements did not reveal the ability to accumulate excessive amounts of Cr, Zn, Pb, Cu, Ni, Fe and Mn, undesired from the usefulness for consumption point of view. Cadmium, irrespective of the examined stage of plant development, revealed high capacity for an excessive accumulation in the top parts. The contents and reciprocal ratios of macroelements in plants changed variously with their growth. The highest Na and K contents were noticed at budding phase, Ca at vegetative stage (arborescent and Mg at the initial budding. The widest Ca:P ratio and K:(Ca+Mg ratio occurred at budding, whereas K:Na ratio at full maturity phase. Linseed accumulated macro- and microele ments in the yield at various rates. Among the analysed elements Cd, Zn and Ni were taken up proportionally to increasing yields of linseed top part biomass.

    A part of the Gangetic Alluvial Plain covering 2,228 km(2), in the state of Bihar, is studied for demarcating groundwater development potential zones. The area is mainly agrarian and experiencing intensive groundwater draft to the tune of 0.12 million cubic metre per square kilometres per year from the Quaternary marginal alluvial deposits, unconformably overlain northerly sloping Precambrian bedrock. Multiparametric data on groundwater comprising water level, hydraulic gradient (pre- and post-monsoon), aquifer thickness, permeability, suitability of groundwater for drinking and irrigation and groundwater resources vs. draft are spatially analysed and integrated on a Geographical Information System platform to generate thematic layers. By integrating these layers, three zones have been delineated based on groundwater development potential. It is inferred that about 48% of the area covering northern part has high development potential, while medium and low development potential category covers 41% of the area. Further increase in groundwater extraction is not recommended for an area of 173 km(2), affected by over-exploitation. The replenishable groundwater resource available for further extraction has been estimated. The development potential enhances towards north with increase in thickness of sediments. Local deviations are due to variation of-(1) cumulative thickness of aquifers, (2) deeper water level resulting from localised heavy groundwater extraction and (3) aquifer permeability.

    2004-01-01

    India embarked on a programme to harness nuclear technologies for the welfare of the nation more than five decades ago and adopted an approach involving knowledge generation through research and development, disseminating the knowledge acquired to the young generation through in-house arrangement, encouraging the researchers in the university system to work on problems of interest to the nuclear industry by providing research funding, networking with the university system, collaborating with industry to upgrade their skills to take up challenging manufacturing jobs, setting up industry under the control of the Government wherever private industry was not coming forward and so on. The basic approach underlying all efforts was to tap the 'knowledge' wherever available and to upgrade the 'knowledge' by R and D. For developing new technologies and for problem solving, 'bottoms up approach' implying study of scientific basis of all issues beginning from fundamentals was used and shortcuts were avoided. This has enabled the country to be self sufficient in all aspects of nuclear fuel cycle as well as applications of radiation technology to industry, agriculture and health care. This also enabled the industry to gain skills and use the skills gained for other sectors of economy. Now that the industry in India is much more mature and the engineering education at the post-graduate level is well developed, several changes in the approach followed have been made. These include making use of the skills and size of the industry by ordering total systems of a power plant rather than individual components and involving industry as consultants for several jobs, which were done in-house in the earlier days. The paper summarizes Indian experience of the last five decades and what is planned for the future. (author)

    2013-01-01

    In recent years there have been several heat waves affecting the use of thermoelectric power plants, e.g. in Europe and the U.S. In this paper the linkage between hydro-climatic conditions and possible electricity generation restrictions is described. The coupling of hydrological models and a power plant model is presented. In this approach each power plant is considered separately with its technical specifications. Also environmental regulations, e.g. permissible rise in the cooling water temperature, are considered for the respective power plant. The hydrological models developed to simulate river runoff and water temperature are also site specific. The approach presented is applied to Krümmel nuclear power plant in Germany. Analysed are the uncertainties with regard to electricity generation restrictions on account of climatic developments and corresponding higher water temperatures and low flows. Overall, increased water temperatures and declining river runoff lead to more frequent and more severe generation restrictions. It is concluded that the site-specific approach is necessary to reliably simulate power plants water demand, river runoff and water temperature. Using a simulation time step of one day, electricity generation restrictions are significantly higher than for simulations at monthly time step. - Highlights: • An approach to assess climate effects on electricity generation is presented. • Site specific models for power plants, water temperature and discharge are used. • Monthly and daily simulation time-steps give different results. • Climate change effects on generation depend on cooling system and climate scenario

    2014-01-01

    Full Text Available This paper deals with the issue of the management cycle of Competitive Intelligence. The author describes the process of Competitive Intelligence in Czech corporate management. He concludes that in most cases, the Competitive Intelligence operations are directed by the top management, and the attention of Competitive Intelligence is being paid to Key Intelligence Topics (KIT. The Competitive Intelligence is then focused on the output of strategic analyses, complemented in some cases with a summary (synthesis of acquired intelligence plus some signal intelligence (SIGINT. The results of the Competitive Intelligence produced in such a way are actually the outputs mostly applicable in operational management and mostly unsuitable for strategic management. However, top managers abroad almost invariably need the data relevant to the future situation since their decisions are of strategic nature. The following section of the paper is devoted to the conceptual solution of Competitive Intelligence, i.e. the Competitive Intelligence objectives linked with the development strategy of the corporation. Here the author arrives at three basic development strategies: a. the corporation desires status quo, i.e. to keep its market position as it is, b. the corporation is out to expand, and c. the corporation intends not only to keep its existing and dominant market position but strives for its long-term dominance to last.

    The selection of protective measures and of remediation strategies of areas after a nuclear or radiological accident needs to be based on previously established criteria, in way to minimize the public's emotional stress and the exposure to workers involved in cleanup operations due to the implementation of procedures that are not effective in reducing doses to the public. Thus this work intended to develop a database which allows supporting the decision-making process after these accidents, by describing the foreseen strategies according to the type of accident and the type of affected environment, in order to be used in a multi-criteria selective process. To achieve that, in this first stage, the database has been developed including the following aspects: type of environment (urban, rural or aquatic); their contamination removal efficiency, as function of the time elapsed since the contamination event; the type and the amount of waste generated in the application of the strategy; the expected doses to the work team and basic needs such as specific materials, equipment, training, IPE, among others. The protection measures are usually described in literature considering their activity removal efficiency of a certain surface or environment. In order to determine their efficiency in the reduction of doses, a second stage is foreseen, involving the simulation of the implementation of the measures in different moments after the contamination, based on pre-defined accidents and scenarios, with focus on the surroundings of the Brazilian Nuclear Power Plants in Angra dos Reis.

    Pharmaceutical biotechnology has a long tradition and is rooted in the last century, first exemplified by penicillin and streptomycin as low molecular weight biosynthetic compounds. Today, pharmaceutical biotechnology still has its fundamentals in fermentation and bioprocessing, but the paradigmatic change affected by biotechnology and pharmaceutical sciences has led to an updated definition. The biotechnology revolution redrew the research, development, production and even marketing processes of drugs. Powerful new instruments and biotechnology related scientific disciplines (genomics, proteomics) make it possible to examine and exploit the behavior of proteins and molecules. Recombinant DNA (rDNA) technologies (genetic, protein, and metabolic engineering) allow the production of a wide range of peptides, proteins, and biochemicals from naturally nonproducing cells. This technology, now approximately 25 years old, is becoming one of the most important technologies developed in the 20(th) century. Pharmaceutical products and industrial enzymes were the first biotech products on the world market made by means of rDNA. Despite important advances regarding rDNA applications in mammalian cells, yeasts still represent attractive hosts for the production of heterologous proteins. In this review we describe these processes.

    Full Text Available Abstract: The teaching of English in Indonesia has so far been unable to reach its declared goal, which is the students' mastery of the English macro skills listening, speaking, reading, writing. Various factors have certainly contributed to this failure, but the highly centralized curriculum has been one of the many to be blamed for it. The new system of regional autonomy gives ample opportunity to schools/ regions to develop their own curricula. This will lead to the need for the establishment of standard of English to ensure the achievement of the ultimate goal of teaching English throughout the country. This paper suggests that the development of standards for English should involve as many parties concerned as possible, including EFL teachers, EFL teacher educators, and users of school graduates. Another suggestion made related to the aspects to be covered in the standards, namely (1 the qualification of EFL policy makers, EFL teacher educators, and EFL teachers; (2 class size, (3 facilities and equipment, and (4 assessment and evaluation.

    Full Text Available Blind people have been, over time, a reason for motivation in the development of solutions to improve their quality of life. The aim of this work is to propose a solution for one of such problems, namely, the selection and combination of clothing for the blind. Thus, this paper describes the whole project developed, in agreement with the Portuguese Association of the Blind and Amblyopic of Portugal (ACAPO, for the creation of a Web platform to aid the blind in selecting combinations of clothing. Near Field Communication (NFC technology is the basis of this project in the identification of garments. The features of the garments are inserted manually, and a combination of features is possible. There is also the possibility to automatically identify the color of the garment. The system has been tested by the ACAPO organization and preliminary feedback is positive, which are a good starting point for the future. This solution helps promote an increased autonomy for blind people.

    Global terrestrial carbon cycle largely depends on a spatial pattern in land cover type, which is heterogeneously-distributed over regional and global scales. However, most studies, which aimed at the estimation of carbon exchanges between ecosystem and atmosphere, remained within several tens of kilometers grid spatial resolution, and the results have not been enough to understand the detailed pattern of carbon exchanges based on ecological community. Improving the sophistication of spatial resolution is obviously necessary to enhance the accuracy of carbon exchanges. Moreover, the improvement may contribute to global warming awareness, policy makers and other social activities. In this study, we show global terrestrial carbon exchanges (net ecosystem production, net primary production, and gross primary production) with 1km-grid resolution. As methodology for computing the exchanges, we 1) developed a global 1km-grid climate and satellite dataset based on the approach in Setoyama and Sasai (2013); 2) used the satellite-driven biosphere model (Biosphere model integrating Eco-physiological And Mechanistic approaches using Satellite data: BEAMS) (Sasai et al., 2005, 2007, 2011); 3) simulated the carbon exchanges by using the new dataset and BEAMS by the use of a supercomputer that includes 1280 CPU and 320 GPGPU cores (GOSAT RCF of NIES). As a result, we could develop a global uniform system for realistically estimating terrestrial carbon exchange, and evaluate net ecosystem production in each community level; leading to obtain highly detailed understanding of terrestrial carbon exchanges.

    At the beginning of 1996, Government has set up the Technology Development Program for High Speed Railways as a national project. Accordingly, the detailed action planning has been established with the collaboration works between Ministry of Construction and Transport and Ministry of Commerce and Trade. On the other hand, the current technology status of domestic manufacturer and many related organizations in Korea only reveals the lack of capabilities in producing the high speed trains. Without the technology transfer programs from the advanced foreign manufacturer (GEC-Alsthom), the domestic manufacturers could not produce HSR. Korea Electrotechnology Research Institute has steered the study to integrate the domestic engineering and technology units specialized in the diversified areas by formulating the feasible collaboration structure between KERI and many organizations on the technology basis. The long term action planning both with the strategic guide and on the technology basis shall be the key function to upgrade the current technology status feasibly for development of the advanced high speed train of 350 km/h.

  1. The potential of socio-psychological models for the development of prevention programs (Part 1

    Directory of Open Access Journals (Sweden)

    Bovina I.B.

    2014-12-01

    Full Text Available This paper considers the problem of designing prevention programs in health and disease. We note that smoking cessation on the planet would reduce mortality from various types of cancer by 25%, and would also save the lives of hundreds of thousands of people who die each year from heart attacks. Losing weight by only 10% through proper nutrition and exercise would reduce the incidence of cardiovascular disease, as well as certain types of cancer. Based on the literature review, we reveal the different types of prevention, show the importance of preventive measures aimed at the patient's immediate environment. Among the main difficulties associated with the development of effective prevention programs we discuss the following: 1 ignoring the psychological mechanisms of behavior change; 2 irrelevance of media broadcast methods in prevention campaigns; 3 the time between the problem behavior and its negative effects on health. We discuss the potential of social influence models for the development of prevention programs in the field of health and disease.

    The development of a questionnaire to measure patients' and their parents' expectations before orthodontic treatment, and to test the reliability and validity of this measure. A two-stage methodology, with open-ended interviews to identify themes and concepts followed by development and testing of the questionnaire. GKT Orthodontic Department, King's College Dental Hospital. The sample consisted of 140 participants, 70 patients aged 12-14 years, who had been referred to the orthodontic department for treatment. One parent of each patient was also recruited. The study was in two phases. In the first phase 30 participants (15 new patients and their 15 parents) participated in open-ended interviews, which were analysed qualitatively. Information from these interviews was used to construct a questionnaire. During the second phase, the questionnaire was piloted on 10 participants, five new consecutive patients and their parents. The questionnaire was then distributed to 174 subjects (87 new patients and their 87 parents). Seventy-eight subjects (39 new patients and their 39 parents) completed the questionnaire before their orthodontic consultation. Another 96 subjects (48 new patients and their 48 parents) were invited to complete the questionnaire prior to and at their orthodontic consultation. Test-retest analysis was conducted on 22 participants (11 patients and their 11 parents), who completed the questionnaire previous to and at their orthodontic consultation, and contributed to the psychometric validation of this questionnaire. A questionnaire was devized using the key themes and concepts identified in the open-ended interviews. As a result, 10 questions, some with sub-questions were constructed using a visual analogue scale as the response format. The questionnaire developed had good face validity. Internal consistency of the questionnaire using Cronbach's alpha, produced an overall inter-item reliability > 0.7 along with item-total correlations > 0.3 in over 50

    The influence of injection technology on the fuel-air mixing process and the combustion development are analyzed by means of visualization techniques. For this purpose, two injectors (one solenoid and one piezoelectric) are characterized using an optical accessible two stroke engine. Visualization of liquid penetration has allowed the measurement of the stabilized liquid length, which is related with the efficiency of fuel-air mixing process. A theoretical derivation is used in order to relate this liquid length with chamber conditions, as well as to make a temporal analysis of these phenomena. After this, natural flame emission and chemiluminescence techniques are carried out. These results indicate that the piezoelectric system has a more efficient fuel-air mixing and combustion, reducing the characteristic times as well as soot formation. Finally, a correlation for the ignition delay of the two systems is obtained. (author)

    To test the performance of nuclear fuels, coolant needs to be circulated through the test rig installed in the test loop. Because the pressure and temperature of the coolant is 15.5 MPa and 300 .deg. C respectively, coolant sealing is one of the most important processes in fabricating a nuclear fuel test rig. In particular, 15 instrumentation cables installed in a test rig pass through the pressure boundary, and brazing is generally applied as a sealing method. In this study, an induction brazing system has been developed using a high frequency induction heater including a vacuum chamber. For application in the nuclear field, BNi2 should be used as a paste, and optimal process variables for Ni brazing have been found by several case studies. The performance and soundness of the brazed components has been verified by a tensile test, cross section test, and sealing performance test.

    The development of mechanical properties has been studied in a test program comprising 15 different concrete mixes with 3 different w/c ratios and different additions of superabsorbent polymers (SAP). The degree of hydration is followed for 15 corresponding paste mixes. This paper concerns...... compressive strength. It shows that results agree well with a model based on the following: 1. Concrete compressive strength is proportional to compressive strength of the paste phase 2. Paste strength depends on gel space ratio, as suggested by Powers 3. The influence of air voids created by SAP...... on compressive strength can be accounted for in the same way as when taking the air content into account in Bolomeys formula. The implication of the model is that at low w/c ratios (w/c SAP additions, SAP increases the compressive strength at later ages (from 3 days after casting and onwards...

    The South Carolina solar industry has surged over the past two years, largely due to the implementation of Act 236, and continues to grow at a rapid pace. At the beginning of 2014, there was little more than 3MW total spread across the state, but by the end of 2021, that state solar industry will have grown to over 300MW across all sectors. Prior to this study, there has been little publically available information on the solar industry in SC and throughout the Southeastern US. This makes SC a key case study of an emerging market, enabling the development of regional best practices in order to decrease associated costs and increase deployment.

    A well designed hybrid energy system can be cost effective, has a high reliability and can improve the quality of life in remote rural areas. The economic constraints can be met, if these systems are fundamentally well designed, use appropriate technology and make use effective dispatch control techniques. The first paper of this tri-series paper, presents the analysis and design of a mixed integer linear mathematical programming model (time series) to determine the optimal operation and cost optimization for a hybrid energy generation system consisting of a photovoltaic array, biomass (fuelwood), biogas, small/micro-hydro, a battery bank and a fossil fuel generator. The optimization is aimed at minimizing the cost function based on demand and potential constraints. Further, mathematical models of all other components of hybrid energy system are also developed. This is the generation mix of the remote rural of India; it may be applied to other rural areas also. (author)

  8. Toward a General Theory for Multiphase Turbulence Part I: Development and Gauging of the Model Equations

    Energy Technology Data Exchange (ETDEWEB)

    B. A. Kashiwa; W. B. VanderHeyden

    2000-12-01

    A formalism for developing multiphase turbulence models is introduced by analogy to the phenomenological method used for single-phase turbulence. A sample model developed using the formalism is given in detail. The procedure begins with ensemble averaging of the exact conservation equations, with closure accomplished by using a combination of analytical and experimental results from the literature. The resulting model is applicable to a wide range of common multiphase flows including gas-solid, liquid-solid and gas-liquid (bubbly) flows. The model is positioned for ready extension to three-phase turbulence, or for use in two-phase turbulence in which one phase is accounted for in multiple size classes, representing polydispersivity. The formalism is expected to suggest directions toward a more fundamentally based theory, similar to the way that early work in single-phase turbulence has led to the spectral theory. The approach is unique in that a portion of the total energy decay rate is ascribed to each phase, as is dictated by the exact averaged equations, and results in a transport equation for energy decay rate associated with each phase. What follows is a straightforward definition of a turbulent viscosity for each phase, and accounts for the effect of exchange of fluctuational energy among phases on the turbulent shear viscosity. The model also accounts for the effect of slip momentum transfer among the phases on the production of turbulence kinetic energy and on the tensor character of the Reynolds stress. Collisional effects, when appropriate, are included by superposition. The model reduces to a standard form in limit of a single, pure material, and is expected to do a credible job of describing multiphase turbulent flows in a wide variety of regimes using a single set of coefficients.

  9. Sediment carbon fate in phreatic karst (Part 1): Conceptual model development

    2017-06-01

    Recent research has paid increased attention to quantifying the fate of carbon pools within fluvial networks, but few, if any, studies consider the fate of sediment organic carbon in fluviokarst systems despite that karst landscapes cover 12% of the earth's land surface. The authors develop a conceptual model of sediment carbon fate in karst terrain with specific emphasis upon phreatic karst conduits, i.e., those located below the groundwater table that have the potential to trap surface-derived sediment and turnover carbon. To assist with their conceptual model development, the authors study a phreatic system and apply a mixture of methods traditional and novel to karst studies, including electrical resistivity imaging, well drilling, instantaneous velocimetry, dye tracing, stage recording, discrete and continuous sediment and water quality sampling, and elemental and stable carbon isotope fingerprinting. Results show that the sediment transport carrying capacity of the phreatic karst water is orders of magnitude less than surface streams during storm-activated periods promoting deposition of fine sediments in the phreatic karst. However, the sediment transport carrying capacity is sustained long after the hydrologic event has ended leading to sediment resuspension and prolonged transport. The surficial fine grained laminae occurs in the subsurface karst system; but unlike surface streams, the light-limited conditions of the subsurface karst promotes constant heterotrophy leading to carbon turnover. The coupling of the hydrological processes leads to a conceptual model that frames phreatic karst as a biologically active conveyor of sediment carbon that recharges degraded organic carbon back to surface streams. For example, fluvial sediment is estimated to lose 30% of its organic carbon by mass during a one year temporary residence within the phreatic karst. It is recommended that scientists consider karst pathways when attempting to estimate organic matter stocks

    A system is being developed to separate trivalent actinides from lanthanide fission product elements that uses 2-ethylhexylphosphonic acid mono-2-ethylhexyl ester to extract the lanthanide ions into an organic phase, while the actinide ions are held in the citrate-buffered aqueous phase by complexation to N-(2-hydroxyethyl)ethylenediamine-N,N',N'-triacetic acid (HEDTA). Earlier investigations of this system using a 2-cm centrifugal contactor revealed that the relatively slow extraction of Sm3+, Eu3+, and Gd3+ resulted in low separation factors from Am3+. In the work reported here, adjustments to the aqueous phase chemistry were made to improve the extraction rates. The results suggest that increasing the concentration of the citric acid buffer from 0.2 to 0.6 mol/L, and lowering the pH from 3.1 to 2.6, significantly improved lanthanide extraction rates resulting in an actinide/lanthanide separation system suitable for deployment in centrifugal contactors. Experiments performed to evaluate whether the lanthanide extraction rates can be improved by replacing aqueous HEDTA with nitrilotriacetic acid (NTA) exhibited promising results. However, NTA exhibited an unsatisfactorily high distribution value for Am3+ under the extraction conditions examined.

    A three-phase model capable of predicting the heat transfer and moisture migration for soil freezing process was developed based on the Shen-Chen model and the mechanisms of heat and mass transfer in unsaturated soil freezing. The pre-melted film was taken into consideration, and the relationship between film thickness and soil temperature was used to calculate the liquid water fraction in both frozen zone and freezing fringe. The force that causes the moisture migration was calculated by the sum of several interactive forces and the suction in the pre-melted film was regarded as an interactive force between ice and water. Two kinds of resistance were regarded as a kind of body force related to the water films between the ice grains and soil grains, and a block force instead of gravity was introduced to keep balance with gravity before soil freezing. Lattice Boltzmann method was used in the simulation, and the input variables for the simulation included the size of computational domain, obstacle fraction, liquid water fraction, air fraction and soil porosity. The model is capable of predicting the water content distribution along soil depth and variations in water content and temperature during soil freezing process.

    Ground layer turbulence is a very important site characterization parameter used to assess the quality of an astronomical site. The Lunar Scintillometer is a simple and effective site-testing device for measuring the ground layer turbulence. It consists of a linear array of photodiodes which are sensitive to the slight variations in the moon's brightness due to scintillation by the lower layers of the Earth's atmosphere. The covariance of intensity values between the non-redundant photodiode baselines can be used to measure the turbulence profile from the ground up to a height determined by the furthest pair of detectors. The six channel lunar scintillometer that has been developed at the Indian Institute of Astrophysics is based closely on an instrument built by the team led by Andrei Tokovinin of Cerro Tololo Inter-American Observatory (CTIO), Chile (Tokovinin et al., Mon. Not. R. Astron. Soc. 404(3), 1186-1196 2010). We have fabricated the instrument based on the existing electronic design, and have worked on the noise analysis, an EMI (Electromagnetic Induction) resistant PCB design and the software pipeline for analyzing the data from the same. The results from the instrument's multi-year campaign at Mount Saraswati, Hanle is also presented.

    The Savannah River Site (SRS) tritium facilities have used first generation (Gen1) LaNi{sub 4.25}Al{sub 0.75} (LANA0.75) metal hydride storage beds for tritium absorption, storage, and desorption. The Gen1 design utilizes hot and cold nitrogen supplies to thermally cycle these beds. Second and third generation (Gen2 and Gen3) storage bed designs include heat conducting foam and divider plates to spatially fix the hydride within the bed. For thermal cycling, the Gen2 and Gen3 beds utilize internal electric heaters and glovebox atmosphere flow over the bed inside the bed external jacket for cooling. The currently installed Gen1 beds require replacement due to tritium aging effects on the LANA0.75 material, and cannot be replaced with Gen2 or Gen3 beds due to different designs of these beds. At the end of service life, Gen1 bed desorption efficiencies are limited by the upper temperature of hot nitrogen supply. To increase end-of-life desorption efficiency, the Gen1 bed design was modified, and a Thermal Enhancement Cartridge Heater Modified (TECH Mod) bed was developed. Internal electric cartridge heaters in the new design to improve end-of-life desorption, and also permit in-bed tritium accountability (IBA) calibration measurements to be made without the use of process tritium. Additional enhancements implemented into the TECH Mod design are also discussed. (authors)

    PANDA is a key experiment of the future FAIR facility, under construction in Darmstadt, Germany. It will study the collisions between an antiproton beam and a fixed proton or nuclear target. The Micro Vertex Detector (MVD) is the innermost detector of the apparatus and is composed of four concentric barrels and six forward disks, instrumented with silicon hybrid pixel detectors and double-sided silicon microstrip detectors; its main task is the identification of primary and secondary vertices. The central requirements include high spatial and time resolution, trigger-less readout with high rate capability, good radiation tolerance and low material budget. Because of the compact layout of the system, its integration poses significant challenges. The detectors in the strip barrels will be supported by a composite structure of carbon fiber and carbon foam; a water-based cooling system embedded in the mechanical supports will be used to remove the excess heat from the readout electronics. In this contribution the design of the barrel stave and the ongoing development of some hardware components related to its integration will be presented.

    In support of NASA's Exoplanet Exploration Program and the Technology Development for Exoplanet Missions (TDEM), we recently completed a 2 year study of the manufacturability and metrology of starshade petals. An external occult is a satellite employing a large screen, or starshade, that flies in formation with a spaceborne telescope to provide the starlight suppression needed for detecting and characterizing exoplanets. Among the advantages of using an occulter are the broadband allowed for characterization and the removal of light before entering the observatory, greatly relaxing the requirements on the telescope and instrument. This poster presents the results of our successful first TDEM that demonstrated an occulter petal could be built and measured to an accuracy consistent with close to 10^-10 contrast. We also present the progress in our second TDEM to demonstrate the next critical technology milestone: precision deployment of the central truss and petals to the necessary accuracy. We have completed manufacture of four sub-scale petals and a central hub to fit with an existing deployable truss. We show the plans for repeated stow and deploy tests of the assembly and the metrology to confirm that each deploy repeatably meets the absolute positioning requirements of the petals (better than 1.0 mm).

    This work focuses on developing filaments of high-density polyethylene (HDPE) and their hollow particle-filled syntactic foams for commercial three-dimensional (3D) printers based on fused filament fabrication technology. Hollow fly-ash cenospheres were blended by 40 wt.% in a HDPE matrix to produce syntactic foam (HDPE40) filaments. Further, the recycling potential was studied by pelletizing the filaments again to extrude twice (2×) and three times (3×). The filaments were tensile tested at 10-4 s-1, 10-3 s-1, and 10-2 s-1 strain rates. HDPE40 filaments show an increasing trend in modulus and strength with the strain rate. Higher density and modulus were noticed for 2× filaments compared to 1× filaments because of the crushing of some cenospheres in the extrusion cycle. However, 2× and 3× filament densities are nearly the same, showing potential for recycling them. The filaments show better properties than the same materials processed by conventional injection molding. Micro-CT scans show a uniform dispersion of cenospheres in all filaments.

    In 2008, Kaiser Permanente began phased implementation of a nationwide performance improvement (PI) system. The aim was to improve performance by providing consistent, highly meaningful performance measurement, increase PI skills in staff at all levels, develop organizational capabilities, and provide support for making improvements in medical centers and across regions. Evaluating the PI System: The intermediate results of the PI system were assessed in the 22 medical centers in four of the eight Kaiser Permanente regions. Implementation for 3 of these medical centers occurred in January 2008 through November 2008, with implementation for the remaining 19 medical centers occurring from September 2008 through September 2009. The 22 medical centers that were evaluated achieved a 61% improvement in selected capabilities, and improvement advisors (IAs) successfully completed 84% of initial PI projects. For each dollar invested, estimates suggested an average return on investment of $2.36. Critical factors include adequate dedicated time for PI activities by staff with necessary expertise, expert support to operations, alignment of projects with regional and national strategic priorities, and close working relationships between PI staff and operational management. Involving finance leaders in improvement planning, prioritization, and oversight is important. These elements can be adapted to smaller systems and single hospitals. The initial evaluation of the Kaiser Permanente PI system indicated that (1) IAs successfully led projects in conjunction with frontline teams, (2) organizational capabilities increased, and (3) the investment in PI infrastructure and staff was sound. Expansion throughout the entire Kaiser Permanente system is under way.

    A mathematical model, based on the Activated Sludge Model No.3 (ASM3), is developed to describe the storage and growth activities of denitrifiers in aerobic granules under anoxic conditions. In this model, mass transfer, hydrolysis, simultaneous anoxic storage and growth, anoxic maintenance, and endogenous decay are all taken into account. The model established is implemented in the well-established AQUASIM simulation software. A combination of completely mixed reactor and biofilm reactor compartments provided by AQUASIM is used to simulate the mass transport and conversion processes occurring in both bulk liquid and granules. The modeling results explicitly show that the external substrate is immediately utilized for storage and growth at feast phase. More external substrates are diverted to storage process than the primary biomass production process. The model simulation indicates that the nitrate utilization rate (NUR) of granules-based denitrification process includes four linear phases of nitrate reduction. Furthermore, the methodology for determining the most important parameter in this model, that is, anoxic reduction factor, is established. (c) 2007 Wiley Periodicals, Inc.

    Since 1998, The Pennsylvania State University successfully managed the Consortium for Premium Carbon Products from Coal (CPCPC), which was a vehicle for industry-driven research on the promotion, development, and transfer of innovative technologies on premium carbon products from coal to the U.S. industry. The CPCPC was an initiative led by Penn State, its cocharter member West Virginia University (WVU), and the U.S. Department of Energy's (DOE) National Energy Technology Laboratory (NETL), who also provided the base funding for the program, with Penn State responsible for consortium management. CPCPC began in 1998 under DOE Cooperative Agreement No. DE-FC26-98FT40350. This agreement ended November 2004 but the CPCPC activity continued under cooperative agreement No. DE-FC26-03NT41874, which started October 1, 2003 and ended December 31, 2010. The objective of the second agreement was to continue the successful operation of the CPCPC. The CPCPC enjoyed tremendous success with its organizational structure, which included Penn State and WVU as charter members, numerous industrial affiliate members, and strategic university affiliate members together with NETL, forming a vibrant and creative team for innovative research in the area of transforming coal to carbon products. The key aspect of CPCPC was its industry-led council that selected proposals submitted by CPCPC members to ensure CPCPC target areas had strong industrial support. CPCPC had 58 member companies and universities engaged over the 7-year period of this contract. Members were from 17 states and five countries outside of the U.S. During this period, the CPCPC Executive Council selected 46 projects for funding. DOE/CPCPC provided $3.9 million in funding or an average of $564,000 per year. The total project costs were $5.45 million with $1.5 million, or ~28% of the total, provided by the members as cost share. Total average project size was $118,000 with $85,900 provided by DOE/CPCPC.

    The Critical Incident Reporting System (CIRS) is a tool for employees to report anonymously of near misses. Its efficiency and improvement of safety is proved by many studies. Our department introduced CIRS in 2009 and it is used frequently. As the number of reports decreased over time we asked for factors responsible for the reduced use. All employees had access to CIRS and have been trained in several courses of instruction. Accomplished results and consequences were published in biannual newsletters. In 2014 we initiated an anonymous employee attitude survey to ask for their experience and satisfaction with CIRS. 88 near misses were reported since 2009. 44 (50%) reports were classified as RS1, 34 (38.6%) as RS2, and 10 (11.4%) as RS3. No RS4 reports were notified. Most reports concerned problems with administration of medication (n=26; 29.5%) and problems with technical devices (n=18; 20.5%). 75 (83%) of our employees participated in the survey. 64 (86.5%) discerned that CIRS is anonymous. 31 (41.9%) reported already a near miss. Of note, two-third didn't realize an improvement following their report. On the other hand, only half of the pollees stated to read the newsletter. Even if efficiency and advantages of CIRS are proved and undeniable, sufficient and perpetual feedback of results and improvements developed by the CIRS team and regular trainings of the employees are mandatory for the success of CIRS. © Georg Thieme Verlag KG Stuttgart · New York.

    Though several methods exist to produce bulk crystals of gallium nitride (GaN), none have been commercialized on a large scale. The sodium flux method, which involves precipitation of GaN from a sodium-gallium melt supersaturated with nitrogen, offers potentially lower cost production due to relatively mild process conditions while maintaining high crystal quality. We successfully developed a novel apparatus for conducting crystal growth of bulk GaN using the sodium flux method which has advantages with respect to prior reports. A key task was to prevent sodium loss or migration from the growth environment while permitting N2 to access the growing crystal. We accomplished this by implementing a reflux condensing stem along with a reusable capsule containing a hermetic seal. The reflux condensing stem also enabled direct monitoring of the melt temperature, which has not been previously reported for the sodium flux method. Furthermore, we identified and utilized molybdenum and the molybdenum alloy TZM as a material capable of directly containing the corrosive sodium-gallium melt. This allowed implementation of a crucible-free system, which may improve process control and potentially lower crystal impurity levels. Nucleation and growth of parasitic GaN ("PolyGaN") on non-seed surfaces occurred in early designs. However, the addition of carbon in later designs suppressed PolyGaN formation and allowed growth of single crystal GaN. Growth rates for the (0001) Ga face (+c-plane) were up to 14 μm/h while X-ray omega rocking (ω-XRC) curve full width half-max values were 731″ for crystals grown using a later system design. Oxygen levels were high, >1019 atoms/cm3, possibly due to reactor cleaning and handling procedures.

    An experiment investigating flow and heat transfer of long (length to diameter ratio of 18) cylindrical film cooling holes has been completed. In this paper, the thermal field in the flow and on the surface of the film cooled flat plate is presented for nominal freestream turbulence intensities of 1.5 and 8 percent. The holes are inclined at 30deg above the downstream direction, injecting chilled air of density ratio 1.0 onto the surface of a flat plate. The diameter of the hole is 0.75 in. (0.01905 m) with center to center spacing (pitch) of 3 hole diameters. Coolant was injected into the mainstream flow at nominal blowing ratios of 0.5, 1.0, 1.5, and 2.0. The Reynolds number of the freestream was approximately 11,000 based on hole diameter. Thermocouple surveys were used to characterize the thermal field. Infrared thermography was used to determine the adiabatic film effectiveness on the plate. Hotwire anemometry was used to provide flowfield physics and turbulence measurements. The results are compared to existing data in the literature. The aim of this work is to produce a benchmark dataset for Computational Fluid Dynamics (CFD) development to eliminate the effects of hole length to diameter ratio and to improve resolution in the near-hole region. In this report, a Time-Filtered Navier Stokes (TFNS), also known as Partially Resolved Navier Stokes (PRNS), method that was implemented in the Glenn-HT code is used to model coolant-mainstream interaction. This method is a high fidelity unsteady method that aims to represent large scale flow features and mixing more accurately.

    Nuclear pumps are characterized by high safety standards, operational reliability as well as long life cycles. For the design process it is of common use to have a down scaled model pump to qualify operating data and simulate exceptional operating conditions. In case of modifications of the pump design compared to existing reactor coolant pumps a model pump is required to develop methods and tools to design the full scale pump. In the presented case it has a geometry scale of 1:2 regarding the full scale pump size. The experimental data of the model pump is basis for validation of methods and tools which are applied in the designing process of the full scale pump. In this paper the selection of qualified tools and the validation process is demonstrated exemplarily on a cooling circuit. The aim is to predict the resulting flow rate. Tools are chosen for different components depending on the benefit to effort ratio. For elementary flow phenomena such as fluid flow in straight pipes or gaps analytic or empirical laws can be used. For more complex flow situations numerical methods are utilized. Main focus is set on the validation process of the applied numerical flow simulation. In this case not only integral data should be compared, it is also necessary to validate local flow structure of numerical flow simulation to avoid systematic errors in CFD Model generation. Due to complex design internal flow measurements are not possible. On that reason simple comparisons of similar flow test cases are used. Results of this study show, that the flow simulation data closely match measured integral pump and test case data. With this validation it is now possible to qualify CFD simulations as a design tool for the full scale pump in similar cooling circuit. (authors)

    The broad conclusion to be drawn from this review is that, at present, there are unlikely to be significant environmental consequences arising from oil and gas production activities. After appropriate treatment of the discharges, the environmental impacts are not expected to be worse than those associated with urban developments. The review found that the main processes (apart from oil spills) identified as having greatest potential environmental effect were: discharges causing physico-chemical or toxic effects, as well as physical effects or disruption of the environment. The discharges may include: drill fluids/muds/cuttings (covered in the drilling activities review), produced water, deck drainage, sewage and domestic waste, cooling water, produced sands ,chronic oil spills (covered in the oil spills review), platform and pipeline hydro-testing. The physical effects are related to: platform placement, pipeline placement, noise, lights/flares, aesthetics. The review presents a number of positive findings. Thus, high dilutions of effluent discharges are expected to occur at many of the sites and so any impact at these sites is expected to be small. Moreover, discharges are subject to the requirements of the Commonwealth Petroleum (Submerged Lands) Act, 1967 as well as State Environment Protection Policies and in some cases the local Department of Minerals and Energy. Thus, the discharge licences for the facilities include a specification of the allowable concentrations of effluents. A range of shortcomings was also noted, including in the existing knowledge, in the specific understanding of the particular marine environments and with respect to limitations in the monitoring programs. 327 refs., 37 tabs., 88 figs

    Texas Instruments is a product intensive company that manufactures very high volumes of different products, and because of this, their technique in manufacturing is what we call hard tooling. So all of the tools we use at this site whether it is for HFIR, ORR or HFBR are hard tooling. A fuel plate never sees a lathe, milling machine, or any other tool of that nature. I have just a few viewgraphs here that will illustrate some of the types of tooling we use to keep away from machining and get high production at as low as possible cost. Figure I shows weighing aluminum powder. It's done in a glove box more to keep air flow away from the balance than any other reason. The weighing of the U 3 O 8 is similar and the glove box is for personnel protection. Figure 2 shows our blender, and I won't try to explain why it works. This is the only one we have ever found that really blends our powder and does a good job. Figure 3 shows our powder die on the press, and you can see the rectangular compact being extracted. Here is the way we make our frames in a blanking die Figure 4. You will notice there are two holes in the frame. We start off with two cores in a frame. Our lot size is 24, but twelve billets go into the furnace for preheating, at the seventh pass, we cut the two cores apart and at that point they become individual fuel plates. Figure 5 shows the loading of the compacts into the frame. We use a loose fit. We can just drop the cores into the frame with, I think, about 2 mils side clearance and it works very satisfactorily. Figure 6 shows a forming die. Once you make the investment for the fuel plate blanking die shown in Figure 7, you can blank out a fuel plate on the order of about one per minute, to size and to the tolerances required. Figure 8 shows a unique tool developed at Oak Ridge. It's a Homogeneity Scanner. It works on the principal of x-ray attenuation going through an electronic analysis

  11. Experimental evidence of inter-blade cavitation vortex development in Francis turbines at deep part load condition

    Francis turbines are subject to various types of cavitation flow depending on the operating condition. To enable a smooth integration of the renewable energy sources, hydraulic machines are now increasingly required to extend their operating range, especially down to extremely low discharge conditions called deep part load operation. The inter-blade cavitation vortex is a typical cavitation phenomenon observed at deep part load operation. However, its dynamic characteristics are insufficiently understood today. In an objective of revealing its characteristics, the present study introduces a novel visualization technique with instrumented guide vanes embedding the visualization devices, providing unprecedented views on the inter-blade cavitation vortex. The binary image processing technique enables the successful evaluation of the inter-blade cavitation vortex in the images. As a result, it is shown that the probability of the inter-blade cavitation development is significantly high close to the runner hub. Furthermore, the mean vortex line is calculated and the vortex region is estimated in the three-dimensional domain for the comparison with numerical simulation results. In addition, the on-board pressure measurements on a runner blade is conducted, and the influence of the inter-blade vortex on the pressure field is investigated. The analysis suggests that the presence of the inter-blade vortex can magnify the amplitude of pressure fluctuations especially on the blade suction side. Furthermore, the wall pressure difference between pressure and suction sides of the blade features partially low or negative values near the hub at the discharge region where the inter-blade vortex develops. This negative pressure difference on the blade wall suggests the development of a backflow region caused by the flow separation near the hub, which is closely related to the development of the inter-blade vortex. The development of the backflow region is confirmed by the numerical

    In order to perform studies of the influence of regional groundwater flow systems on the long-term performance of potential high-level nuclear waste repositories, it was determined that an adequate computer model would have to consider the full three-dimensional flow system. Golder Associates' SOLTR code, while three-dimensional, has an overly simple algorithm for simulating the passage of radionuclides from one aquifier to another above or below it. Part 1 of this report describes the algorithm developed to provide SOLTR with an improved capability for simulating interaquifer transport

    Horn, A.J.; Sherry, A.H.

    2012-01-01

    This Part I paper describes a new engineering assessment methodology for ferritic steel structures containing non-sharp defects within the context of a Failure Assessment Diagram (FAD) approach. Although the modification of the FAD for non-sharp defects can be applied whether the initiating failure mechanism is cleavage or ductile tearing, this paper focuses on cleavage fracture. The parameters describing the sensitivity of the material toughness to the notch effect can either be measured by testing notched specimens of the same thickness as the structure, or for cleavage fracture they can be obtained using look-up tables generated using the Weibull stress toughness scaling model. The other parameters in the procedure can either be conservatively estimated using simple equations or they can be determined more accurately using finite element analysis. Validation of the new method is presented in the companion Part II paper: this shows that assessments of U-notched SE(B) specimens have significantly reduced conservatism when using the new assessment methodology compared to the standard FAD approach for sharp cracks. - Highlights: ► Development of a new procedure for predicting failure from non-sharp defects. ► Based on a modification of the Failure Assessment Diagram (FAD) approach. ► Applicable to cleavage and ductile tearing initiation although paper focuses on cleavage. ► Validation provided in a companion Part II paper.

    The morphology of the temporal part of the human temporomandibular joint (TMJ) changes drastically during postnatal development. The glenoid fossa will acquire its characteristic S shape and a tubercle will develop. The combined results of the literature and of this study allow a reconstruction of the actual growth processes. The roof of the glenoid fossa appears to enlarge forward by remodeling while sagittal and vertical growth is mainly achieved by deposition at the top of the tubercle. These latter changes result in a steeper slope of the eminence and take place in 3 phases, parallelling the eruption of the first incisors, the permanent first molars and the permanent second molars. While the zygomatic arch thickens by deposition at all surfaces, it also remodels downward relative to the external meatus. As a result, the neonate anulus occupies a lower position relative to this arch than does the adult meatus.

    Measurement and characterization of subvisible particles (defined here as those ranging in size from 2 to 100 μm), including proteinaceous and nonproteinaceous particles, is an important part of every stage of protein therapeutic development. The tools used and the ways in which the information generated is applied depends on the particular product development stage, the amount of material, and the time available for the analysis. In order to compare results across laboratories and products, it is important to harmonize nomenclature, experimental protocols, data analysis, and interpretation. In this manuscript on perspectives on subvisible particles in protein therapeutic drug products, we focus on the tools available for detection, characterization, and quantification of these species and the strategy around their application. © 2015 Wiley Periodicals, Inc. and the American Pharmacists Association.

  16. Rotary Bed Reactor for Chemical-Looping Combustion with Carbon Capture. Part 1: Reactor Design and Model Development

    KAUST Repository

    2013-01-17

    Chemical-looping combustion (CLC) is a novel and promising technology for power generation with inherent CO2 capture. Currently, almost all of the research has been focused on developing CLC-based interconnected fluidized-bed reactors. In this two-part series, a new rotary reactor concept for gas-fueled CLC is proposed and analyzed. In part 1, the detailed configuration of the rotary reactor is described. In the reactor, a solid wheel rotates between the fuel and air streams at the reactor inlet and exit. Two purging sectors are used to avoid the mixing between the fuel stream and the air stream. The rotary wheel consists of a large number of channels with copper oxide coated on the inner surface of the channels. The support material is boron nitride, which has high specific heat and thermal conductivity. Gas flows through the reactor at elevated pressure, and it is heated to a high temperature by fuel combustion. Typical design parameters for a thermal capacity of 1 MW have been proposed, and a simplified model is developed to predict the performances of the reactor. The potential drawbacks of the rotary reactor are also discussed. © 2012 American Chemical Society.

    The dichotic digits test is one of the most widely used assessment tools for central auditory processing disorder. However, questions remain concerning the impact of cognitive factors on test results. To develop the Dichotic Digits difference Test (DDdT), an assessment tool that could differentiate children with cognitive deficits from children with genuine dichotic deficits based on differential test results. The DDdT consists of four subtests: dichotic free recall (FR), dichotic directed left ear (DLE), dichotic directed right ear (DRE), and diotic. Scores for six conditions are calculated (FR left ear [LE], FR right ear [RE], and FR total, as well as DLE, DRE, and diotic). Scores for four difference measures are also calculated: dichotic advantage, right-ear advantage (REA) FR, REA directed, and attention advantage. Experiment 1 involved development of the DDdT, including error rate analysis. Experiment 2 involved collection of normative and test-retest reliability data. Twenty adults (aged 25 yr 10 mo to 50 yr 7 mo, mean 36 yr 4 mo) took part in the development study; 62 normal-hearing, typically developing, primary-school children (aged 7 yr 1 mo to 11 yr 11 mo, mean 9 yr 4 mo) and 10 adults (aged 25 yr 0 mo to 51 yr 6 mo, mean 34 yr 10 mo) took part in the normative and test-retest reliability study. In Experiment 1, error rate analysis was conducted on the 36 digit-pair combinations of the DDdT. Normative data collected in Experiment 2 were arcsine transformed to achieve a distribution that was closer to a normal distribution and z-scores calculated. Pearson product-moment correlations were used to determine the strength of relationships between DDdT conditions. The development study revealed no significant differences in the adult population between test and retest on any DDdT condition. Error rates on 36 digit pairs ranged from 1.5% to 16.7%. The most and the least error-prone digits were removed before commencement of the normative data study, leaving 25

    Although advocates and providers identify stigma as a major factor in confounding the recovery of people with SUDs, research on addiction stigma is lacking, especially when compared to the substantive literature examining the stigma of mental illness. A comprehensive review of the stigma literature that yielded empirically supported concepts and methods from the mental health arena was contrasted with the much smaller and mostly descriptive findings from the addiction field. In Part I of this two part paper (American Journal of Addictions, Vol 26, pages 59-66, this issue), constructs and methods from the mental health stigma literature were used to summarize research that seeks to understand the phenomena of addiction stigma. In Paper II, we use this summary, as well as the extensive literature on mental illness stigma change, to outline a research program to develop and evaluate strategies meant to diminish impact on public and self-stigma (eg, education and contact). The paper ends with recommendations for next steps in addiction stigma research. (Am J Addict 2017;26:67-74). © 2016 American Academy of Addiction Psychiatry.

    2000-01-01

    This first part of a series on developments in the European gas market features the growth in gas supply. 35% of the gas demand must be covered from sources outside Europe. For the future additional imports are required from countries such as the Russian Federation, Algeria and Nigeria. Over the next few years the artificial link between ga and oil prices will disappear, bringing the gas price to a structurally lower level. It will be of crucial importance that gas suppliers will not be able to form cartels to keep prices high. All competing projects will curb price increases on the European market, but will definitely result in more freedom of choice for European natural gas consumers

    The ceramic tiles manufactured in Sergipe State are classified in Absorption 'BIIb' Group. Studies have been developed to obtain the classification 'BIIa' Group. This first part is about the mineralogical characterization of raw materials used for ceramics tiles, collected for three different fields. The mineralogical characterization was made with: X-ray Diffraction, Infrared, Thermogravimetric and Differential Thermal Analysis, and was also obtained clays plasticity indices. The samples were heated up to 500 deg C, 900° C and 1100° C. Clays were classified as highly plastics and moderately plastics with a large number of grain with size order smaller than 0,074 mm. The main minerals identified were: kaolinite, illite, montmorillonite, quartz, feldspar and calcite. Two of the three studied fields had high calcite content. The Calcite retards the sintering process causing higher porosity to the ceramic tiles. (author)

    The growing demands from analytical community, for a precise isotope ratio and ultra trace concentration measurements, has lead to significant improvement in mass spectrometer instrumentation development with respect to sensitivity, detection limits, precision and accuracy. Among the many analytical techniques available, plasma source mass spectrometers like Inductively Coupled Plasma Mass Spectrometry (ICPMS), multi collector (MC) ICPMS and Glow Discharge Mass Spectrometry (GDMS), have matured into reliable tools for the above applications. Where as ICPMS is by far the most successful method for aqueous solutions, GDMS is being applied for bulk and impurity analysis of conducting as well non-conducting solids. VPID, BARC has been developing mass spectrometers for different inorganic applications of DAE users. Over the years expertise has been developed in all the aspects of mass spectrometry instrumentation. Part 1 of this indigenous instrumentation on mass spectrometry gives details of magnetic sector instruments with either EI or TI source for isotopic ratio analysis. The present paper is a continuation of that on plasma source and quadrupole mass spectrometers. This paper covers i) ICP-QMS, ii) MC-ICPMS, iii) GDMS and iv) QMS

    To use parts of the APhA Career Pathway Evaluation Program for Pharmacy Professionals in a career development laboratory designed to provide students with relevant information that will help them prepare for successful careers across the profession of pharmacy. Students enrolled in the second professional year of pharmacy school participated in an interactive three-hour career development laboratory. Students completed the APhA Career Pathway Evaluation Program for Pharmacy Professionals Online Assessment Tool prior to the laboratory. In class, the students were randomized into eight groups. Two career profiles were assigned to each group for discussion during a thirty-minute brainstorming session. The groups reported their knowledge for each career profile to the entire class, and the instructors supplemented the discussion with details and more specific information about each profile. Two years of data were collected (n=300 students). One hundred and twenty four (41.3%) students responded to the voluntary post-laboratory survey questions. Overall, students rated the career pathway activities favorably with an average score of 8.13 out of 10. After participation in the discussion, 74 (59.7%) respondents indicated their career interests had been impacted. This career development laboratory is one example of how the APhA Career Pathway Evaluation Program for Pharmacy Professionals can be effectively incorporated into the PharmD curriculum in order to help students explore the various career options they might not have otherwise discovered on their own.

    In a previous paper, we have discussed the intelligent Windows 95-based data management program(IDPIN) which was developed for effective and efficient management of large amounts of pre-/in-service inspection(PSI/ISI) data of Kori nuclear power plants. The IDPIN program enables the prompt extraction of previously conducted PSI/ISI conditions and results so that the time-consuming data management, painstaking data processing and analysis of the past are avoided. In this study, the intelligent Windows based data management program(WS-IDPIN) has been developed as an effective data management of PSI/ISI data for the Wolsong nuclear power plants. The WS-IDPIN program includes the modules of comprehensive management and analysis of PSI/ISI results, statistical reliability assessment program of PSI/ISI results(depth and length sizing performance etc), standardization of UT report form and computerization of UT results. In addition, the program can be further developed as a unique PSI/ISI data management expert system which can be part of the PSI/ISI total support system for Korean nuclear power plants

    A novel analytical system AWACSS (automated water analyser computer-supported system) based on immunochemical technology has been developed that can measure several organic pollutants at low nanogram per litre level in a single few-minutes analysis without any prior sample pre-concentration nor pre-treatment steps. Having in mind actual needs of water-sector managers related to the implementation of the Drinking Water Directive (DWD) (98/83/EC, 1998) and Water Framework Directive WFD (2000/60/EC, 2000), drinking, ground, surface, and waste waters were major media used for the evaluation of the system performance. The instrument was equipped with remote control and surveillance facilities. The system's software allows for the internet-based networking between the measurement and control stations, global management, trend analysis, and early-warning applications. The experience of water laboratories has been utilised at the design of the instrument's hardware and software in order to make the system rugged and user-friendly. Several market surveys were conducted during the project to assess the applicability of the final system. A web-based AWACSS database was created for automated evaluation and storage of the obtained data in a format compatible with major databases of environmental organic pollutants in Europe. This first part article gives the reader an overview of the aims and scope of the AWACSS project as well as details about basic technology, immunoassays, software, and networking developed and utilised within the research project. The second part article reports on the system performance, first real sample measurements, and an international collaborative trial (inter-laboratory tests) to compare the biosensor with conventional anayltical methods.

    The state and key tendencies of the development of basic technologies for manufacture of photoelectric converters (PECs) in the world are considered, and their advantages and disadvantages are discussed. The first part of the review gives short information on the development of photovoltaics in the world and planes of the development of solar power plants in Russia. Total power of photoelectric plants operating in various countries in 2015 exceeded 150 GW and increased in the last ten years with a rate of approximately 50% per year. Russia made important state decisions on the support of the development of renewable power engineering and developed mechanisms, which were attractive for business, on the stimulation of building of the network of solar power plants with a total power to 1.5 GW in the country to 2020. At the same time, the rigid demands are made with respect to the localization of the production of components of these plants that opens new abilities for the development of the domestic production of photovoltaics manufacture. Data on the efficiency of PECs of various types that are attained in the leading laboratories of the world are given. Particular emphasis has been placed on the consideration of basic silicon technologies of PEC manufacture, which had the widest commercial application. The basic methods for production of polycrystalline silicon and making single-crystal and multicrystal silicon are described. Fundamentals of making techniques for plates, PECs, and photoelectric modules based on single-crystal and polycrystalline silicon are considered. The second part will be devoted to modifications of manufacturing techniques for photoelectric converters, enhancement methods for contact structures, and recommendations of authors with respect to the choice of prospective technologies for the expansion of PEC production in Russia. It will involve formulations and substantiations of the most promising lines of the development of photoelectric

    The objective of this project is the development of a procedure for the qualitative and quantitative evaluation of human factors in the probabilistic safety assessment for nuclear power plants. The Human Error Rate Assessment and Optimizing System (HEROS) is introduced. The evaluation of a task with HEROS is realized in the three evaluation levels, i.e. 'Management Structure', 'Working Environment' and 'Man-Machine-Interface'. The developed expert system uses the fuzzy set theory for an assessment. For the evaluation of cognitive tasks evaluation criteria are derived also. The validation of the procedure is based on three examples, reflecting the common practice of probabilistic safety assessments and including problems, which cannot, respectively - only insufficiently - be evaluated with the established human risk analysis procedures. HERO applications give plausible and comprehensible results. (orig.) [de

    The consideration of inherent population inhomogeneities of mammalian cell cultures becomes increasingly important for systems biology study and for developing more stable and efficient processes. However, variations of cellular properties belonging to different sub-populations and their potential effects on cellular physiology and kinetics of culture productivity under bioproduction conditions have not yet been much in the focus of research. Culture heterogeneity is strongly determined by the advance of the cell cycle. The assignment of cell-cycle specific cellular variations to large-scale process conditions can be optimally determined based on the combination of (partially) synchronized cultivation under otherwise physiological conditions and subsequent population-resolved model adaptation. The first step has been achieved using the physical selection method of countercurrent flow centrifugal elutriation, recently established in our group for different mammalian cell lines which is presented in Part I of this paper series. In this second part, we demonstrate the successful adaptation and application of a cell-cycle dependent population balance ensemble model to describe and understand synchronized bioreactor cultivations performed with two model mammalian cell lines, AGE1.HNAAT and CHO-K1. Numerical adaptation of the model to experimental data allows for detection of phase-specific parameters and for determination of significant variations between different phases and different cell lines. It shows that special care must be taken with regard to the sampling frequency in such oscillation cultures to minimize phase shift (jitter) artifacts. Based on predictions of long-term oscillation behavior of a culture depending on its start conditions, optimal elutriation setup trade-offs between high cell yields and high synchronization efficiency are proposed. © 2014 American Institute of Chemical Engineers.

  12. A development plan for the south-eastern part of Pag island with an emphasis on olive-growing

    2014-01-01

    Full Text Available Regardless of the fact that the traditional usage of rural landscapes was agricultural, a degradation of landscape values, as well as an onset of natural succession, occur due to contemporary lifestyle. This can lead to negative effects regarding land-use change. This paper focuses on the south-eastern part of Pag island and explores the possibilities for the revitalisation of its neglected areas by envisioning its future development as an olive-growing region. The final goal was to define a planning procedure framework which would enable the creation of a strategic vision to be transformed into a comprehensive spatial development strategy for the research area. This area encompasses the territory between Kaštela in the north-west and the Pag’s bridge in the south-east which administratively belongs to the Zadar County and includes the Town of Pag, and the Kolan and Povljana municipalities. Olive-growing has been recognized as the strategic choice for development because of its tradition in the area and the potential integration with other relatable activities. Based on the SWOT analysis, an appropriate mission, a vision and strategic goals were defined for developing Pag as an olive-growing region. Further landscape planning methods included (1 the Lynch mapping analysis, (2 the Forman and Godron landscape ecology analysis and (3 the landscape pattern analysis. The results were then used together with digital orthophoto imagery to overlay and analyse relevant information. Hand drawings as well as AutoCAD, ArcGIS and image editing computer programmes were used in the process. This analytical phase was then followed by the development of several alternative spatial zonings, diagrams and concepts based on a preferable neighbourhood matrix and the activity sizing table. The planning process resulted in a concept for spatial development of the research area which would enable the implementation of the strategic vision. The main goal of this

    As international studies have shown, accidents in plants are increasingly caused by combinations of technical failures and human errors. Therefore careful investigations of man-machine-interactions to determine human reliability are gaining importance worldwide. Regarding nuclear power plants such investigations are usually carried out within the scope of probabilistic safety assessments. A great number of procedures to evaluate human factors has been developed up to now. However, none of them is able to take into account the whole spectrum of requirements - as for instance transferability of date to other plants, analysis of weak points, and evaluation of cognitive tasks - for a complete and reliable probabilistic safety assessment. Based on an advanced model for a man-machine-system, the Human Error Rate Assessment and Optimizing System (HEROS) and a corresponding expert system of the same name are introduced. This expert system enables the quantification of human error probabilities for plant operator actions on the one hand and is also capable of providing quantitative statements regarding the optimization of man-machine-system in terms of human error probability minimization on the other one. Three relevant evaluation levels, i.e. 'Management Structure', 'Working Environment' and 'Man-Machine-Interface', are derived from a model of the man-machine-system. Linguistic variables are assigned to all performance shaping factors at these levels. These variables are used to establish a rule-based expert system. The knowledge bases of this system are represented by rules. Processing of these rules is carried out by means of the fuzzy set theory, after provision of relevant data for a particular personal action to be evaluated. This procedure enables a simple and effective use of ergonomic studies as the relevant database, which is also transferable to other plants with any design. The expert system consist in total of 16 rule bases in which all ascertainable and

    Pneumatic muscle actuators (PMAs) have a high power to weight ratio and possess unique characteristics which make them ideal actuators for applications involving human interaction. PMAs are difficult to control due to nonlinear dynamics, presenting challenges in system implementation. Despite these challenges, PMAs have great potential as a source of resistance for strength training and rehabilitation. The objective of this work was to control a PMA for use in isokinetic exercise, potentially benefiting anyone in need of optimal strength training through a joint's range of motion. The controller, based on an inverse three-element phenomenological model and adaptive nonlinear control, allows the system to operate as a type of haptic device. A human quadriceps dynamic simulator was developed (as described in Part I of this work) so that control effectiveness and accommodation could be tested prior to human implementation. Tracking error results indicate that the control system is effective at producing PMA displacement and resistance necessary for a scaled, simulated neuromuscular actuator to maintain low-velocity isokinetic movement during simulated concentric and eccentric knee extension.

    Full scale and field testing of a simple mechanical stemming aid is described. The aid comprises a solid unit placed in the stemming above the explosive column and is designed to improve blasting efficiency and reduce drilling and blasting costs. It is designed to work with back filled drill cuttings or any other suitable stemming material. The results of Phase I testing were highly successful, indicating that the stemming aid has technically an extremely good chance of success at full scale when constructed of low cost materials. Phase II of the stemming aid research and development program comprised of the testing of various forms of the stemming is at full scale in non-research oriented i.e. field settings. The stemming aid was field tested at 4 different sites for a variety of mining application: First in underground workings at the UMR experimental mine in one and three quarter inch diameter horizontal blast holes incorporated into full blast patterns; three and three and a half inch blast holes at two crushed rock/limestone quarries in the Rolla area and at a surface coal mine operation run by Peabody Coal Company at Lynnville, Indiana in which nine and seven eighths, ten and five eighths and fifteen and a quarter inch diameter blast holes were used for parting and overburden removal. 2 refs., 37 figs., 11 tabs.

    The gun-driven facility for simulating nuclear air blast has been described in Part 1 (AWRE Report 031/74). It was, however, subject to certain limitations in providing the requisite blast parameters for nuclear hardening. The efficiency of the simulator has been improved beyond that of the gun-driven facility to produce blast waves of higher peak overpressure, longer positive duration and greater equivalent yield. This has been done by firing in the 1.8 m (6 ft) diameter section of the tunnel instead of in the guns. Various line charge arrangements were investigated and the pressures and strains developed in the 1.8 m (6 ft) diameter section were measured. The shock loading on the tube walls was less than that produced by firing in the guns and consisted of a short duration shock decaying to a lower amplitude pressure pulse of longer duration (1 ms), followed by a few reflected shocks which the tube walls were well able to withstand. The equipment is described and results discussed. (author)

    1992-01-01

    To place the fundamentals of clinical drug safety surveillance in a conceptual framework that will facilitate understanding and application of adverse drug event data to protect the health of the public and support a market for pharmaceutical manufacturers' products. Part I of this series provides a background for the discussion of drug safety by defining the basic terms and showing the flow of safety information through a pharmaceutical company. The customers for adverse drug event data are identified to provide a basis for providing quality service. The development of a drug product is briefly reviewed to show the evolution of safety data. Drug development and safety are defined by federal regulations. These regulations are developed by the FDA with information from pharmaceutical manufacturers. The intent of the regulations and the accompanying guidelines is described. An illustration from the news media is cited to show an alternative, positive approach to handling an adverse event report. This review uses primary sources from the federal laws (regulations), commentaries, and summaries. Very complex topics are briefly summarized in the text and additional readings are presented in an appendix. Secondary sources, ranging from newspaper articles to judicial summaries, illustrate the interpretation of adverse drug events and opportunities for drug safety surveillance intervention. The reference materials used were articles theoretically or practically applicable in the day-to-day practice of drug safety surveillance. The role of clinical drug safety surveillance in product monitoring and drug development is described. The process of drug safety surveillance is defined by the Food and Drug Administration regulations, product labeling, product knowledge, and database management. Database management is subdivided into the functions of receipt, retention, retrieval, and review of adverse event reports. Emphasis is placed on the dynamic interaction ;of the components

    : Although management practices are recognized as important factors in improving health care quality and efficiency, most research thus far has focused on individual practices, ignoring or underspecifying the contexts within which these practices are operating. Research from other industries, which has increasingly focused on systems rather than individual practices, has yielded results that may benefit health services management. : Our goal was to develop a conceptual model on the basis of prior research from health care as well as other industries that could be used to inform important contextual considerations within health care. : Using theoretical frameworks from A. Donabedian (1966), P. M. Wright, T. M. Gardner, and L. M. Moynihan (2003), and B. Schneider, D. B. Smith, and H. W. Goldstein (2000) and review methods adapted from R. Pawson (2006b), we reviewed relevant research from peer-reviewed and other industry-relevant sources to inform our model. The model we developed was then reviewed with a panel of practitioners, including experts in quality and human resource management, to assess the applicability of the model to health care settings. : The resulting conceptual model identified four practice bundles, comprising 14 management practices as well as nine factors influencing adoption and perceived sustainability of these practices. The mechanisms by which these practices influence care outcomes are illustrated using the example of hospital-acquired infections. In addition, limitations of the current evidence base are discussed, and an agenda for future research in health care settings is outlined. : Results may help practitioners better conceptualize management practices as part of a broader system of work practices. This may, in turn, help practitioners to prioritize management improvement efforts more systematically.

    Full Text Available Current phosphorus (P use in European countries is highly dependent on mineral P imports and not sustainably managed. In order to identify and implement measures for sustainable P management, a comprehensive understanding of national P flows and stocks and their temporal dynamics is essential. We conduct a substance flow analysis (SFA of the Swiss P system of the year 2015, and study the dynamics of the national P system by looking into its development since 1989. Furthermore, we investigate how political-legislative interventions affected the P system during this period. The results show that between 1989 and 2015, the P efficiency in Swiss agriculture increased from 59% to 94%, mainly due to a considerable reduction of fertilization in the agricultural subsystem. At the same time, Switzerland's P import dependency decreased from 33% to 24% between 1989 and 2002 because of a reduction of mineral fertilizer import and use. Between 2002 and 2015, the import dependency stagnated because further improvements in P use efficiency in agriculture were outweighed by a decrease of P recycling and an increase of P losses in the waste management system. By embedding these temporal dynamics in their political-legislative context, we found that top-down interventions such as incentives for a balanced nutrient budget in agriculture, restrictions of the use of animal by-products in the agri-food system or the ban of direct sewage sludge recycling in agriculture significantly affected and shaped the national P system. Our analysis provides profound quantitative and qualitative insights into past and present P management in Switzerland and is followed by part 2 of the paper, where we analyze possible future pathways of P management.

    Additive manufacturing provides an attractive processing method for nickel–titanium (NiTi) shape memory and pseudoelastic parts. In this paper, we show how the additive manufacturing process affects structural and functional properties of additively manufactured NiTi and how the process parameter set-up can be optimized to produce high quality NiTi parts and components. Comparisons of shape recovery due to shape memory and pseudoelasticity in additively manufactured and commercial NiTi exhibit promising potential for this innovative processing method. (paper)

  17. Design and development of a layer-based additive manufacturing process for the realization of metal parts of designed mesostructure

    Science.gov (United States)

    Williams, Christopher Bryant

    Low-density cellular materials, metallic bodies with gaseous voids, are a unique class of materials that are characterized by their high strength, low mass, good energy absorption characteristics, and good thermal and acoustic insulation properties. In an effort to take advantage of this entire suite of positive mechanical traits, designers are tailoring the cellular mesostructure for multiple design objectives. Unfortunately, existing cellular material manufacturing technologies limit the design space as they are limited to certain part mesostructure, material type, and macrostructure. The opportunity that exists to improve the design of existing products, and the ability to reap the benefits of cellular materials in new applications is the driving force behind this research. As such, the primary research goal of this work is to design, embody, and analyze a manufacturing process that provides a designer the ability to specify the material type, material composition, void morphology, and mesostructure topology for any conceivable part geometry. The accomplishment of this goal is achieved in three phases of research: (1) Design---Following a systematic design process and a rigorous selection exercise, a layer-based additive manufacturing process is designed that is capable of meeting the unique requirements of fabricating cellular material geometry. Specifically, metal parts of designed mesostructure are fabricated via three-dimensional printing of metal oxide ceramic powder followed by post-processing in a reducing atmosphere. (2) Embodiment ---The primary research hypothesis is verified through the use of the designed manufacturing process chain to successfully realize metal parts of designed mesostructure. (3) Modeling & Evaluation ---The designed manufacturing process is modeled in this final research phase so as to increase understanding of experimental results and to establish a foundation for future analytical modeling research. In addition to an analysis of

    2013-12-01

    Little is known about the concrete historical sources for the use of neopositivist operational criteria by the DSM-III. This paper suggests that distinct sources operated implicitly. The current usefulness of the operational approach is questioned. It is shown that: (a) in epistemology, neopositivism has been replaced by more adequate accounts; (b) psychologists rejected operational definitions because these were unable to define the majority of mental phenomena; (c) mental symptoms cannot be directly described as such, because they already make part of the psychiatric diagnosis to which they belong. In conclusion, diagnosing is based on the hermeneutical co-construction of mental symptoms. The failure of the neopositivist programme suggests that it is time to reconcile scientific formalization and semiotic activity.

  7. Large-scale production of diesel-like biofuels - process design as an inherent part of microorganism development.

    Cuellar, Maria C; Heijnen, Joseph J; van der Wielen, Luuk A M

    2013-06-01

    Industrial biotechnology is playing an important role in the transition to a bio-based economy. Currently, however, industrial implementation is still modest, despite the advances made in microorganism development. Given that the fuels and commodity chemicals sectors are characterized by tight economic margins, we propose to address overall process design and efficiency at the start of bioprocess development. While current microorganism development is targeted at product formation and product yield, addressing process design at the start of bioprocess development means that microorganism selection can also be extended to other critical targets for process technology and process scale implementation, such as enhancing cell separation or increasing cell robustness at operating conditions that favor the overall process. In this paper we follow this approach for the microbial production of diesel-like biofuels. We review current microbial routes with both oleaginous and engineered microorganisms. For the routes leading to extracellular production, we identify the process conditions for large scale operation. The process conditions identified are finally translated to microorganism development targets. We show that microorganism development should be directed at anaerobic production, increasing robustness at extreme process conditions and tailoring cell surface properties. All the same time, novel process configurations integrating fermentation and product recovery, cell reuse and low-cost technologies for product separation are mandatory. This review provides a state-of-the-art summary of the latest challenges in large-scale production of diesel-like biofuels. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Greenwood, Jennifer; Parsons, Myra

    2002-10-01

    In Western Sydney, Australia, in 1996, the Area Health Service and the University of Western Sydney entered a strategic alliance to develop a nursing research culture in the health services. One of the strategies implemented to achieve this was the establishment of a network of research-receptive environments known as Clinical Development Units (CDUs). In terms of research receptivity, evidence at the time suggested that it could only be developed in units where the leadership style is democratic and participatory. In terms of CDUs, evidence suggested that their successful development depended critically on the effective management of CDU leadership stressors. In light of this, it was agreed to conduct a CDU leadership preparation program in Western Sydney. The program aimed to furnish CDU leaders with the participatory leadership skills required to develop and manage their units. It was expected that the acquisition of such leadership skills would serve to minimize the leadership stessors they could expect to experience. This is the second of two papers which report course evaluation data. The first focused on the more positive evaluation data; this paper focuses on the negative evaluation data and outlines how the current program has been modified in light of these data. In addition, it discusses two themes which emerged during data analysis. These were nurses' apparent mutual lack of trust and their pressing needs to be recognized as valuable and merit-worthy.

    Full Text Available This paper looks at the possibilities that a broad-based innovation policy contained by the national innovation strategy recently adopted in Finland opens up for the promotion of workplace innovations and examines the types of knowledge needed in workplace development. The author highlights the interconnections between workplace development and the prerequisites of both economic growth and the preservation of the Finnish welfare state. The paper also aims to explain why, in addition to the productivity of work, improving the quality of working life should feature as an increasingly important aim in the innovation policy of the future. An argument for the need of three types of knowledge in workplace development - design knowledge, process knowledge and dissemination knowledge - is made, together with an overview on new developments in each of those three domains. In conclusion, the author demonstrates how problems in the productivity of work and the quality of working life can be simultaneously tackled with at work organization level through two kinds of development approaches.

    Full Text Available Background and Purpose: ConsideringBackground and Purpose: Considering the importance and necessity of competency-based education at a global level and with respect to globalization and the requirement of minimum competencies in medical fields, medical education communities and organizations worldwide have tried to determine the competencies, present frameworks and education models to respond to be sure of the ability of all graduates. In the literature, we observed numerous competency development models that refer to the same issues with different terminologies. It seems that evaluation and synthesis of all these models can finally result in designing a comprehensive meta-model for competency development.Methods: Meta-ethnography is a useful method for synthesis of qualitative research that is used to develop models that interpret the results in several studies. Considering that the aim of this study is to ultimately provide a competency development meta-model, in the previous section of the study, the literature review was conducted to achieve competency development models. Models obtained through the search were studied in details, and the key concepts of the models and overarching concepts were extracted in this section, models’ concepts were reciprocally translated and the available competency development models were synthesized.Results: A presentation of the competency development meta-model and providing a redefinition of the Dreyfus brothers model.Conclusions: Given the importance of competency-based education at a global level and the need to review curricula and competency-based curriculum design, it is required to provide competency development as well as meta-model to be the basis for curriculum development. As there are a variety of competency development models available, in this study, it was tried to develop the curriculum using them.Keywords: Meta-ethnography, Competency development, Meta-model, Qualitative synthesis

    In Part 1 of this three-part research series, a leak test performed using high-voltage leak detection (HVLD) technology, also referred to as an electrical conductivity and capacitance leak test, was developed and validated for container-closure integrity verification of a small-volume laminate plastic bag containing an aqueous solution for injection. The sterile parenteral product is the rapid-acting insulin analogue, insulin aspart (NovoRapid®/NovoLog®, by Novo Nordisk A/S, Bagsværd, Denmark). The aseptically filled and sealed package is designed to preserve product sterility through expiry. Method development and validation work incorporated positive control packages with a single hole laser-drilled through the laminate film of each bag. A unique HVLD method characterized by specific high-voltage and potentiometer set points was established for testing bags positioned in each of three possible orientations as they are conveyed through the instrument's test zone in each of two possible directions-resulting in a total of six different test method options. Validation study results successfully demonstrated the ability of all six methods to accurately and reliably detect those packages with laser-drilled holes from 2.5-11.2 μm in nominal diameter. Part 2 of this series will further explore HVLD test results as a function of package seal and product storage variables. The final Part 3 will report the impact of HVLD exposure on product physico-chemical stability. In this Part 1 of a three-part research series, a leak test method based on electrical conductivity and capacitance, called high voltage leak detection (HVLD), was used to find leaks in small plastic bags filled with an insulin pharmaceutical solution for human injection by Novo Nordisk A/S (Bagsværd, Denmark). To perform the test, the package is electrically grounded while being conveyed past an electrode linked to a high-voltage, low-amperage transformer. The instrument measures the current that passes

    The popularity of minimally invasive surgical procedures is driving the development of novel, safer and more accurate surgical tools. In this context a multi-part probe for soft tissue surgery is being developed in the Mechatronics in Medicine Laboratory at Imperial College, London. This study reports an optimization procedure using finite element methods, for the identification of an interlock geometry able to limit the separation of the segments composing the multi-part probe. An optimal geometry was obtained and the corresponding three-dimensional finite element model validated experimentally. Simulation results are shown to be consistent with the physical experiments. The outcome of this study is an important step in the provision of a novel miniature steerable probe for surgery.

    2017-01-01

    Full Text Available In Europe's general context of economic integration, the National States have preserved a few competences. Among them, the most important competence is taxation management, which has now become an important lever to stabilize the State's budget and to meet the economic parameters set by the European Agreements. From this perspective, it is crucial to identify a software development mode to reduce the time spent for the implementation/adjustment of the tax payment software application and, at the same time, to minimize the overall risk level. In software development, approximately 40% of time is spent in a series of testing activities: this stage of the development process is mostly placed at the end of the implementation activities. Consequently, since many testing activities have to be waived in order to meet the deadlines for software delivery, applications that are not entirely in compliance with the user's needs and/or entailing non-compliance are more likely to be introduced. This paper focuses on improving the testing process in tax procedures. The proposed method aims to improve the process, by introducing an integrated procedure based on Axiomatic Design. The approach developed will facilitate a reduction both in the testing preparation time and in performing the test cases. In this scenario, it will be possible to optimize the data compilation process, to verify the compliance within the technical specifications as provided by the Italian Revenue Agency, to identify possible critical scenarios with a proactive approach, and to avoid classes of non-conformities.

    The development of new armour materials, and fabrication and testings of the divertor and first wall mock-ups have worldwidely been carried out during the Conceptual Design Activites (CDA) of ITER. This paper is a review of the activities on the divertor and first wall armour components which has been performed by JAERI, Sandia National Laboratory, and KFA Juelich. The design requirements have instantly been reflected in material development. For instance, carbon fiber composites (CFCs) have already been developed to have a thermal conductivity as high as copper at room temperature. Further modification of CFC's has been made. Based on the extensive progress in armour materials, the fabrication and testings of mock-ups have been started. Divertor mock-ups which are able to endure a stationary heat flux of 8 to 15 MW/m 2 have already been developed. Some new high heat flux test facilities have been constructed and are able to simulate a heat load of plasma disruption. Extensive understanding on disruption erosion of the armour materials has been obtained by experiments with these facilities. Some mock-up tests and disruption simulating tests have been performed under international collaboration. (orig.)

    Public health leadership development programs are widely employed to strengthen leaders and leadership networks and ultimately agencies and systems. The year-long National Public Health Leadership Institute's (PHLI) goals are to develop the capacity of individual leaders and networks of leaders so that both can lead improvement in public health systems, infrastructure, and population health. To evaluate the impact of PHLI on individual graduates using data collected from the first 15 cohorts. Between 1992 and 2006, PHLI graduated 806 senior leaders from governmental agencies, academia, health care, associations, nonprofit organizations, foundations, and other organizations. Of 646 graduates located, 393 (61%) responded to a survey, for an overall response rate of 49% (393/806). PHLI has included retreats; readings, conference calls, and webinars; assessments, feedback, and coaching; and action learning projects, in which graduates apply concepts to a work challenge aided by peers and a coach. A survey of all graduates and interviews of 34 graduates and one other key informant. PHLI improved graduates' understanding, skills, and self-awareness, strengthened many graduates' connections to a network of leaders, and significantly increased graduates' voluntary leadership activities at local, state, and national levels (P supportive peers and ideas, and bolstered confidence and interest in taking on leadership work. Nearly all graduates remained in public health. Some partially attributed to PHLI their promotions into more senior positions. Leadership development programs can strengthen and sustain their impact by cultivating sustained "communities of practice" that provide ongoing support for skill development and innovative practice. Sponsors can fruitfully view leadership development as a long-term investment in individuals and networks within organizations or fields of practice.

    2007-12-01

    This dissertation combines work in the areas of experimental physical chemistry and chemical education. In the area of physical chemistry, femtosecond pump-probe spectroscopy is used to interrogate the time-dependence for energy redistribution, solvent reorientation, and dissociation dynamics in small gas-phase anion clusters. The chemical education research addressed in this manuscript include the development and validation of a survey to measure students' beliefs about chemistry and the learning of chemistry and the development and testing of learning tutorials for use in undergraduate physical chemistry courses in thermodynamics and kinetics. In the first part of this dissertation, the Cu(CD3OD) dynamics are investigated using a combination of femtosecond pump-probe experiments and ab initio calculations. Dissociation of this complex into Cu and CD3OD occurs on two distinct time scales: 3 and 30 ps, which arise, respectively, from the coupling of intermolecular solvent rotations and excited methyl rotor rotation into the Cu-O dissociation component upon electron photodetachment of the precursor anion. In the second part of this dissertation, the time-resolved recombination of photodissociated IBr-(CO2)n (n = 5 - 10) cluster anions is investigated. Upon excitation to the A' 2pi 1/2 state of the chromophore, the bare anion results in I- and Br products, upon solvation with CO2, the IBr- chromophore regains near-IR absorption after recombination and vibrational relaxation on the ground electronic state. The recombination times vary with the number of solvent molecules from 12 ps for n = 5 to 900 ps for n = 10. Extensive electronic structure and non-adiabatic molecular dynamic simulations provide a framework to understand this behavior. In the third part of this dissertation, the modification and validation of the Colorado Learning Attitudes about Science Survey (CLASS) for use in chemistry is presented in detail. The CLASS survey is designed to measure student

To analyze the philosophical and theoretical approaches considered in the development of a new nursing interface terminology called ATIC. Review, analysis and discussion of the main philosophical orientations, high and mid-range theories and nursing scientific literature to develop an interpretative conceptualization of the metaparadigm concepts "Health", "Environment" and "Nursing". In the 2 previous papers the ATIC terminology, its foundation on pragmatism, holism, post-positivism and constructivism and the construction of the meaning for the concept elndividualh is discussed. In this third paper, Health is conceptualized as a multidimensional balance state and the concepts of Partial health status, Disease and Being ill are explored within. The analysis of the Environment theories drives its conceptualization as a group of variables that has the potential to affect health status. In this orientation, Nursing is understood as the scientific discipline focused on the study of health status in the particular environment and experience of the individuals, groups, communities or societies. ATIC terminology is rooted on an eclectic philosophical and theoretical foundation, allowing it to be used from different trends within the totality paradigm.

  10. Developing an Empirical Model for Estimating the Probability of Electrical Short Circuits from Tin Whiskers. Part 2

    To comply with lead-free legislation, many manufacturers have converted from tin-lead to pure tin finishes of electronic components. However, pure tin finishes have a greater propensity to grow tin whiskers than tin-lead finishes. Since tin whiskers present an electrical short circuit hazard in electronic components, simulations have been developed to quantify the risk of said short circuits occurring. Existing risk simulations make the assumption that when a free tin whisker has bridged two adjacent exposed electrical conductors, the result is an electrical short circuit. This conservative assumption is made because shorting is a random event that had an unknown probability associated with it. Note however that due to contact resistance electrical shorts may not occur at lower voltage levels. In our first article we developed an empirical probability model for tin whisker shorting. In this paper, we develop a more comprehensive empirical model using a refined experiment with a larger sample size, in which we studied the effect of varying voltage on the breakdown of the contact resistance which leads to a short circuit. From the resulting data we estimated the probability distribution of an electrical short, as a function of voltage. In addition, the unexpected polycrystalline structure seen in the focused ion beam (FIB) cross section in the first experiment was confirmed in this experiment using transmission electron microscopy (TEM). The FIB was also used to cross section two card guides to facilitate the measurement of the grain size of each card guide's tin plating to determine its finish.

    The conventional seismic design method of nuclear piping system is very conservative because of the accumulation of various safety factors in the design process, and nuclear piping systems are thought to have a large safety margin. Considering this situations, research program was promoted to furthermore rationalize nuclear power plants by reducing the amount of support structures and reducing the piping's seismic response through vibration energy absorption resulting from the elasto-plastic behavior of piping support structures. The research had the following three stages. In the first stage, we selected conventional piping support structures in light-water reactors that exhibited elasto-plastic behavior, and studied the effect of displacement and the vibration frequency on the stiffness and on the energy absorption by testing these models. In the second stage, vibration tests were performed using piping models with support structures on shaking tables. The piping vibration characteristics were clarified by sinusoidal sweep tests and the piping response characteristics by seismic wave vibration tests when the support structures were in an elasto-plastic condition. In the third stage, a general method was developed to evaluate the characteristics of a variety of support structures in the tests. A simplified analysis method was also developed to evaluate the piping seismic response using the piping model test result. To expand the results mentioned above, we also established a new seismic design method of piping systems that allowed support structures to have elasto-plastic behavior. This paper reports the newly developed seismic design method based on the results of experiments conducted under the joint research program of Japanese electric power companies (The Japan Atomic Power Co., Hokkaido EPC, Tohoku EPC, Tokyo EPC, Chubu EPC, Hokuriku EPC, Kansai EPC, Chugoku EPC, Shikoku EPC, Kyushu EPC) and nuclear plant makers (Hitachi Ltd., Toshiba Co., MHI Ltd., HEC Ltd

In the first stage, we select conventional piping support structures in Japanese light-water reactors that exhibit elasto-plastic behavior, and study the displacement dependency and the vibration frequency dependency on the stiffness and the energy absorption by testing their model. In the second stage, we make a piping test model with support structures whose characteristics have already been obtained, and perform vibration tests on a shaking table. In this way, we analyze the piping vibration characteristics by sinusoidal wave sweep tests and the piping response characteristics by seismic wave vibration tests, when the support structures are in an elasto-plastic condition. In the third stage, a general method is developed to evaluate the characteristics of the support structures obtained in the tests and it is applied to the evaluation of the characteristics of general support structures. A simplified analysis method is developed to evaluate the piping seismic response using the piping model test result. To expand the results mentioned above, we are developing a seismic design method of piping systems that allows support structures to have elasto-plastic behaviour.

Within the investigation «Physical and chemical study of nanocomposite materials produced in a template way with the controlled sol-gel synthesis method» new approaches to functionalization of silica matrix with the immobilization of cyclodextrin complexes and APG micelles with solubilizated water insoluble substances which is performed under favourable conditions in aqueous solutions without organic dissolvents were developed. These approaches can be used to produce selective sorbents and luminescence materials. The proposed method of crystall titanium dioxide nanoparticles synthesis which is carried out under room temperature, can be regarded as an alternative for its high-temperature production for photocatalysts, sensors and solar batteries. Within the investigation «Controlled self-organization of azaporphyrins in 2D and 3D nanostructure in Langmuire layers and Langmuir-Blodgett films» it was shown that along with the model design and development of method which determines nanostructured Langmuire layer structure Langmuir-Blodgett (LB technology which allows obtaining nanosized films becomes the tool to study and form 2D and iD-nanostructures in floating layers and LB films as well as to produce thin-film nanomaterials based on organic compounds with developed p-system and possessing specified structure and properties. The designed model also allows solving one of the most important problems in nanotechnology and science on nanomaterials for the low dimension systems – the problem concerning determination of dependency between the size of formed particles and the conditions needed for their formation.

    We have developed a new index, called the resilience index, that evaluates the dynamic stability of the system safety of a nuclear power plant during a severe accident by considering the ability to recover system safety functions that have become lost in the situation. In this paper, a detailed evaluation procedure for the resilience index is described. The system safety of a pressurized water reactor plant during a severe accident is then assessed according to the resilience index in order to discuss the applicability of the index. We find that the resilience index successfully represents management capability and, therefore, the resilience capability of a nuclear power plant. (author)

    There is a spectrum of parental protective behaviors promoting child safety and security, ranging from neglect to overprotection. This paper describes the development and psychometric properties of a new measure of parental protective behaviors toward children age 2 to 10 years, the Parent Protection Scale (PPS). Items were selected to represent key dimensions of protective behaviors. Factor analyses suggested four subscales: Supervision, Separation Problems, Dependence, and Control. The PPS has acceptable internal consistency, test-retest reliability, and clinical validity. Norms by child age in the form of cutoff points corresponding to +1 SD were determined. Clinical and research uses for the PPS are noted.

    The NASA Engineering and Safety Center (NESC) received a request to develop an analysis model based on both frequency response and wave propagation analyses for predicting shock response spectrum (SRS) on composite materials subjected to pyroshock loading. The model would account for near-field environment (approximately 9 inches from the source) dominated by direct wave propagation, mid-field environment (approximately 2 feet from the source) characterized by wave propagation and structural resonances, and far-field environment dominated by lower frequency bending waves in the structure. This document contains appendices to the Volume I report.

    2015-01-01

    A temperature dependent, quantitative free energy functional was developed for the modeling of hydride precipitation in zirconium alloys within a phase field scheme. The model takes into account crystallographic variants of hydrides, interfacial energy between hydride and matrix, interfacial energy between hydrides, elastoplastic hydride precipitation and interaction with externally applied stress. The model is fully quantitative in real time and real length scale, and simulation results were compared with limited experimental data available in the literature with a reasonable agreement. The work calls for experimental and/or theoretical investigations of some of the key material properties that are not yet available in the literature

    Measurement techniques to estimate electrical efficiency of 10 kW-class SOFC systems fueled by town-gas were developed and demonstrated for a system developed by Kansai Electric Power Company and Mitsubishi Materials Corporation under a NEDO project. Higher heating value of the fuel was evaluated with a transportable gas sampling unit and conventional gas chromatography in AIST laboratory with thermal-conductivity and flame-ionization detectors, leading to mean value 44.69 MJ m -3 on a volumetric base for ideal-gas at the standard state (0 deg. C, 101.325 kPa). Mass-flow-rate of the fuel was estimated as 33.04 slm with a mass-flow meter for CH 4 , which was calibrated to correct CH 4 flow-rate and effect of sensitivity change and to obtain conversion factor from CH 4 to town-gas. Without calibration, systematic effect would occur by 8% in flow-rate measurement in the case for CH 4 . Power output was measured with a precision power analyzer, a virtual three phase starpoint adapter, and tri-axial shunts. Power of fundamental wave (60 Hz) was estimated as 10.14 kW, considering from total active power, total higher harmonic distortion factor, and power consumption at the starpoint adapter. The electrical efficiency was presumed to be 41.2% (HHV), though this mean value will be complete only when uncertainty estimation is accompanied

    Full Text Available There has been no systematic appraisal of ethnicity-based variations in breast cancer (BC biology amongst women from developing countries. A qualitative systematic review was conducted of breast cancer size, stage, grade, histological type, extra-mammary involvement, hormone receptor status as well as patient demographics. This review includes patients from Africa, the Middle East, Eastern Europe, Mexico, the Caribbean and South America. BC in these regions present at an earlier age with large aggressive tumours. Distant metastases are frequently present at the time of diagnosis. African women have a higher frequency of triple negative tumours. Over half of Middle Eastern women have lymph node involvement at the time of diagnosis. Despite experiencing a lower incidence compared to the Ashkenazi Jewish population, Palestinian women have poorer five-year survival outcomes. The majority of women from Mexico and South America have stage two or three disease whilst over sixty percent of women from Eastern Europe have either stage one or stage two disease. The biological characteristics of BC in the Caribbean cannot be fully assessed due to a paucity of data from the region. BC amongst the developing world is characterised by an early peak age of onset with aggressive biological characteristics. Strategies that improve breast cancer awareness, address amenable risk factors and improve early detection are essential.

    Full Text Available The ability to introduce various concepts and business models is nowadays a prerequisite of creating a competitive advantage. This is to a large extent closely linked to the ability of enterprises to create, implement and disseminate a variety of innovative solutions. Today the use of open innovation is a necessity. This applies not only to large organisations, but also to small and medium-sized enterprises. In order to implement open innovation, small and medium-sized enterprises need to effectively manage their own growth through the preparation of appropriate strategies and the development of a model that encompasses all changes, taking into account a number of factors related to the growth dynamics of this sector. It is understood that an appropriate organisational culture plays an important role in the implementation of innovation in the sector of small and medium-sized enterprises. There are many indications that a cultural mismatch and misunderstanding are the main reasons for major problems related to the low level of implementation of innovation by small and medium-sized enterprises. The aim of the paper is to outline the issue of the impact of organisational culture on the development of the concept of open innovation in the sector of small and medium-sized enterprises.

    2016-04-01

    Full Text Available The paper analyses the issue of a popular trend called ‘life outsourcing’ which affects the structure of personality in an individual. Basing on the works of L.S. Vygotsky and others, the author explores the methodology of the concept of cultural development as a process of formation of an embodied personality or non-organic body. He outlines the search for the approaches to the process of cultural development and for its descriptions in terms of personality construction and ‘soul organism’ which can be traced down in Vygotsky’s works. According to these works, cultural-historical psychology employed a concept of tool- and activity-based personality body, or soul organism. As it is argued in the paper, this concept is to a certain extent incomplete. What happens to the individual’s personality body in a situation of increasingly popular life outsourcing, i.e. when more and more basic functions and actions are transferred from the individual to various devices? Using artistic creativity as an example, the author explores the artist’s transition from working with natural materials to working with devices and focuses on the problem of the artist’s ‘smart body’ losing the feeling of texture and form. The issue is to be continued in the second paper.

    2016-06-01

    Full Text Available Pipe wall thinning by flow-accelerated corrosion and various types of erosion is a significant and costly damage phenomenon in secondary piping systems of nuclear power plants (NPPs. Most NPPs have management programs to ensure pipe integrity due to wall thinning that includes periodic measurements for pipe wall thicknesses using nondestructive evaluation techniques. Numerous measurements using ultrasonic tests (UTs; one of the nondestructive evaluation technologies have been performed during scheduled outages in NPPs. Using the thickness measurement data, wall thinning rates of each component are determined conservatively according to several evaluation methods developed by the United States Electric Power Research Institute. However, little is known about the conservativeness or reliability of the evaluation methods because of a lack of understanding of the measurement error. In this study, quantitative models for UT thickness measurement deviations of nuclear pipes and fittings were developed as the first step for establishing an optimized thinning evaluation procedure considering measurement error. In order to understand the characteristics of UT thickness measurement errors of nuclear pipes and fittings, round robin test results, which were obtained by previous researchers under laboratory conditions, were analyzed. Then, based on a large dataset of actual plant data from four NPPs, a quantitative model for UT thickness measurement deviation is proposed for plant conditions.

    1995-12-01

    Today, the Danish wind turbine industry is positioned as a global market leader on a fast growing international market. The conclusion and observation of this report are: 1. The international market for wind power is likely to grow fast over the next 5 years (a self-reinforcing development) and the Danish wind turbine industry has the potential to increase export from the present DKK 2 billion per year to DKK 4 billion per year. 2. The leading market position is achieved after the collapse of the California market in 1987. The last four years have been export-driven growth together with the development of complementary assets to support a strong product technology. 3. The Danish position might be threatened by the new competitors, but it is our view that it takes 2-3 years before they have equivalent competences, and since the Danish companies are presently also mobilizing resources and competences it is not likely that they are easily outperformed. 4. A continued installation of wind power in Denmark is important to support the sustaining of the international position in the coming years. Through, it is not the volume size of the domestic market, but rather a stable market which serves as a home base for the industry. Not only for the reference and testing of new wind turbines, but also the knowledge networks between manufacturers and suppliers and between manufacturers and the Test Station for Windmills at Risoe.

    T. A. Bokova

    2016-01-01

    Full Text Available Evaluation of qualitative and quantitative composition of microflora of different habitats of the human body and definition of their role in the development of metabolic disorders are of great interest for investigators worldwide. The gut microbiota is an obligatory contributor to the synthesis, recirculation and metabolism of steroid hormones, lipids, and bile acids. Infectious agents and their biologically active compounds initiate the atherogenesis. Disorders of lipid metabolism are associated with a change in bacterial enterotypes. Microbiotal colonization of gastrointestinal tract starts at birth. Its composition in a newborn depends on a variety of environmental and nutritional factors, maternal health, the course of pregnancy and delivery. Infants born by cesarean section have a higher incidence of obesity, which is thought to be associated with a delay of bifidobacterial colonization of gastrointestinal tract.Reduction of bifidobacteria counts in the gut in infants below 12 months of age predisposes to obesity in later life. Children born to mothers with obesity have significant differences in the composition of the gut microflora, compared to children born to normal weight mothers. This review presents the data on the association between metabolic disorders, such as obesity and type 2 diabetes, and persistence of Helicobacter pylori infection. Further in-depth research in this area would increase the knowledge on the mechanisms of hormonal and metabolic disorders in childhood and may help to develop algorithms for effective treatment and preventive measures.

    Student nurses often embark on their professional careers with a lack of the knowledge and confidence necessary to navigate them successfully. An ongoing process of career planning and development (CPD) is integral to developing career resilience, one key attribute that may enable nurses to respond to and influence their ever-changing work environments with the potential outcome of increased job satisfaction and commitment to the profession. A longitudinal mixed methods study of a curriculum-based CPD program was conducted to determine the program's effects on participating students, new graduate nurses, and faculty. This first in a series of three papers about the overall study's components reports on undergraduate student outcomes. Findings demonstrate that the intervention group reported higher perceived career resilience than the control group, who received the standard nursing curriculum without CPD. The program offered students the tools and resources to become confident, self-directed, and active in shaping their engagement in their academic program to help achieve their career goals, whereas control group students continued to look uncertainly to others for answers and direction. The intervention group recognized the value of this particular CPD program and both groups, albeit differently, highlighted the key role that faculty played in students' career planning.

    The scope of this study was to develop and validate a questionnaire (QCirDental) to measure the impacts associated with dental extraction surgery. The QCirDental questionnaire was developed in two steps; (1) question and item generation and selection, and (2) pretest of the questionnaire with evaluation of the its measurement properties (internal consistency and responsiveness). The sample was composed of 123 patients. None of the patients had any difficulty in understanding the QCirDental. The instrument was found to have excellent internal consistency with Cronbach's alpha reliability coefficient of 0.83. The principal component analysis (Kaiser-Meyer-Olkin Measure of Sampling Adequacy 0,72 and Bartlett's Test of Sphericity with p < 0.001) showed six (6) dimensions explaining 67.5% of the variance. The QCirDental presented excellent internal consistency, being a questionnaire that is easy to read and understand with adequate semantic and content validity. More than 80% of the patients who underwent dental extraction reported some degree of discomfort within the perioperative period which highlights the necessity to assess the quality of care and impacts of dental extraction surgery.

    2008-01-01

    The aim of this study is to assess the ecological characteristics of El-Daba'a area in Egypt using GIS as a first step for the development of an environmental management plan for the area. The absence of environmental planning in the process of land use development may cause many significant negative impacts on biodiversity, ecological value and the general environmental conditions and the therefore reducing such negative impacts will improve land use development. The first part of sequel of two papers, which is a part of a sustainable land use development research program, aims at designing a spatial framework to improve land use planning and development in an environmental context. The research program deals with the problem of land use planning and development in an arid coastal area under environmentally sensitive conditions. The study area is El-Daba'a region, located in the northwestern coast of Egypt, which can be described as a wild area. The approach used in this paper consists of studying the spatial ecological characteristics of El-Daba'a region using different spatial data including maps and land sat remote sensing data. These data are used to create a series of superimposed informative layers managed by a geographic information system (GIS) to describe the spatial ecological characteristics of the study area. The developed GIS allow decision makers to handle large amounts of information simultaneously such as geology, geomorphology, land cover, wild life and many other different information layers. The system is designed to help decision makers to organize, relate, analyze and visualize the ecological data and information in the study area. The developed GIS system might be used to determine the probable effects of building a nuclear power station on the ecosystem. (author)

    Catastrophic incidents can generate a large number of samples of analytically diverse types, including forensic, clinical, environmental, food, and others. Environmental samples include water, wastewater, soil, air, urban building and infrastructure materials, and surface residue. Such samples may arise not only from contamination from the incident but also from the multitude of activities surrounding the response to the incident, including decontamination. This document summarizes a range of activities to help build laboratory capability in preparation for sample analysis following a catastrophic incident, including selection and development of fit-for-purpose analytical methods for chemical, biological, and radiological contaminants. Fit-for-purpose methods are those which have been selected to meet project specific data quality objectives. For example, methods could be fit for screening contamination in the early phases of investigation of contamination incidents because they are rapid and easily implemented, but those same methods may not be fit for the purpose of remediating the environment to acceptable levels when a more sensitive method is required. While the exact data quality objectives defining fitness-for-purpose can vary with each incident, a governing principle of the method selection and development process for environmental remediation and recovery is based on achieving high throughput while maintaining high quality analytical results. This paper illustrates the result of applying this principle, in the form of a compendium of analytical methods for contaminants of interest. The compendium is based on experience with actual incidents, where appropriate and available. This paper also discusses efforts aimed at adaptation of existing methods to increase fitness-for-purpose and development of innovative methods when necessary. The contaminants of interest are primarily those potentially released through catastrophes resulting from malicious activity

  17. SEBAL-A: A Remote Sensing ET Algorithm that Accounts for Advection with Limited Data. Part I: Development and Validation

    Directory of Open Access Journals (Sweden)

    Mcebisi Mkhwanazi

    2015-11-01

    Full Text Available The Surface Energy Balance Algorithm for Land (SEBAL is one of the remote sensing (RS models that are increasingly being used to determine evapotranspiration (ET. SEBAL is a widely used model, mainly due to the fact that it requires minimum weather data, and also no prior knowledge of surface characteristics is needed. However, it has been observed that it underestimates ET under advective conditions due to its disregard of advection as another source of energy available for evaporation. A modified SEBAL model was therefore developed in this study. An advection component, which is absent in the original SEBAL, was introduced such that the energy available for evapotranspiration was a sum of net radiation and advected heat energy. The improved SEBAL model was termed SEBAL-Advection or SEBAL-A. An important aspect of the improved model is the estimation of advected energy using minimal weather data. While other RS models would require hourly weather data to be able to account for advection (e.g., METRIC, SEBAL-A only requires daily averages of limited weather data, making it appropriate even in areas where weather data at short time steps may not be available. In this study, firstly, the original SEBAL model was evaluated under advective and non-advective conditions near Rocky Ford in southeastern Colorado, a semi-arid area where afternoon advection is common occurrence. The SEBAL model was found to incur large errors when there was advection (which was indicated by higher wind speed and warm and dry air. SEBAL-A was then developed and validated in the same area under standard surface conditions, which were described as healthy alfalfa with height of 40–60 cm, without water-stress. ET values estimated using the original and modified SEBAL were compared to large weighing lysimeter-measured ET values. When the SEBAL ET was compared to SEBAL-A ET values, the latter showed improved performance, with the ET Mean Bias Error (MBE reduced from −17

    A skill requirement definition method was applied to the problem of determining, at an early stage in system/mission definition, the skills required of on-orbit crew personnel whose activities will be related to the conduct or support of earth-orbital research. The experiment data base was selected from proposed experiments in NASA's earth orbital research and application investigation program as related to space shuttle missions, specifically those being considered for Sortie Lab. Concepts for two integrated workstation consoles for Sortie Lab experiment operations were developed, one each for earth observations and materials sciences payloads, utilizing a common supporting subsystems core console. A comprehensive data base of crew functions, operating environments, task dependencies, task-skills and occupational skills applicable to a representative cross section of earth orbital research experiments is presented. All data has been coded alphanumerically to permit efficient, low cost exercise and application of the data through automatic data processing in the future.

    Howington, L.C.

    1977-12-01

    An instrumentation system (Aging Integrator) has been developed to provide more precise control of the heat-treatment process used on uranium-0.75 wt.% titanium alloy material. The Aging Integrator calculates the integral of a predetermined aging function to control the aging period in the heat-treatment process. This control was employed to compensate for discrepancies caused by variations in heatup times, furnace-control fluctuations, and disagreement as to the temperature at which aging actually starts. Although the Aging Integrator hardware has been installed and satisfactorily tested on a production-area furnace, sufficient data to estimate a statistically sound aging integration function will not be available for approximately one year

    The venous system alters its function in pregnancy--the changes are both functional and structural. It becomes particularly vulnerable to the development of venous thrombosis and related complications. These adverse factors acting on the veins in pregnancy include: an increase in circulating blood volume, expansion of the uterus, weight gain, reduced physical activity hormonal changes. The changes in the plasma have a significant impact on the venous system. In pregnancy an increased level of fibrinogen and coagulation factors VII, VIII, IX and X, and von Willenbrand factor can be observed. Smooth muscle relaxation and relaxation of collagen fibers are caused by progesterone and estrogen, and it may result in the development of varicose veins, venous thrombosis and venous insufficiency The relationships between the hormones and the muscle pump efficiency has not been proven as yet. Estrogens cause an increase in the synthesis of coagulation proteins and it may result in the high risk of venous thrombosis and its consequences. Progesterone inhibits smooth muscle contraction, while estrogens cause relaxation and loosening of the bonds between the collagen fibers. The increase in the level of progesterone is of particular importance. It has a relaxing effect on the muscle, resulting in disorders of the vein shrinkage, affecting the increase of their capacity and valvular insufficiency, and valvular edges are not in contact with each other due to the vasodilatation. Estrogens have a similar effect, and additionally it may also cause an impairment in the collagen fibers connection and synthesis. This can result in the formation of telanglectasia without venous hypertension. Estrogens may also affect the synthesis of prostaglandins and nitric oxide. Estradiol inhibits vascular smooth muscle cell proliferation and stimulates cell migration and secretion of matrix proteins, as well as regeneration of the damaged vessels. Estrogen inhibits the production of cytokines

    In order to verify the mathematical model of an ice bank system developed for the purpose of predicting the system performance, experimental measurements on the ice bank system were performed. Static, indirect, cool thermal storage system, with an external ice-on-coil building/melting was considered. Cooling energy stored in the form of ice by night is used for the rapid cooling of milk after the process of pasteurization by day. The ice bank system was tested under real operating conditions to determine parameters such as the time-varying heat load imposed by the consumer, refrigeration unit load, storage capacity, supply water temperature to the load and to find charging and discharging characteristics of the storage. Experimentally obtained results were then compared to the computed ones. It was found that the calculated and experimentally obtained results are in good agreement as long as there is ice present in the silo. (author)

    Highlights: ► Domestic heat loads here are vast: 1.5 GW for current areas and 35 MW for new homes. ► Other heat sinks in Sheffield had a heat load/demand of 54 MW. ► New heat sources could provide additional heat to the network to meet these demands. ► Six ‘heat zones’ for possible district energy network expansions were identified. ► The infrastructure was planned, including energy centres, back-ups and heat pipes. - Abstract: District heating can provide cost-effective and low-carbon energy to local populations, such as space heating in winter and year-round hot/cold water; this is also associated with electricity generation in combined-heat-and-power systems. Although this is currently rare in the UK, many legislative policies, including the Renewable Heat Incentive, aim to increase the amount of energy from such sources; including new installations, as well as extending/upgrading existing distributed energy schemes. Sheffield already has an award-winning district energy network, incorporating city-wide heat distribution. This paper aimed to demonstrate the opportunities for expansions to this through geographical information systems software modelling for an in-depth analysis of the heat demands in the city. ‘Heat maps’ were produced, locating existing and emerging heat sources and sinks. Heat loads (industrial, commercial, educational, health care, council and leisure facilities/complex) total 53 MW, with existing residential areas accounting for ∼1500 MW and new housing developments potentially adding a further 35 MW in the future. A number of current and emerging heat sources were also discovered – potential suppliers of thermal energy to the above-defined heat sinks. From these, six ‘heat zones’ where an expansion to the existing network could be possible were identified and the infrastructure planned for each development.

    This article presents the evidence base for 'operator models' - that is, how to deliver a sustainable service through the interaction of the 'client', 'revenue collector' and 'operator' functions - for municipal solid waste management in emerging and developing countries. The companion article addresses a selection of locally appropriate operator models. The evidence shows that no 'standard' operator model is effective in all developing countries and circumstances. Each city uses a mix of different operator models; 134 cases showed on average 2.5 models per city, each applying to different elements of municipal solid waste management - that is, street sweeping, primary collection, secondary collection, transfer, recycling, resource recovery and disposal or a combination. Operator models were analysed in detail for 28 case studies; the article summarises evidence across all elements and in more detail for waste collection. Operators fall into three main groups: The public sector, formal private sector, and micro-service providers including micro-, community-based and informal enterprises. Micro-service providers emerge as a common group; they are effective in expanding primary collection service coverage into poor- or peri-urban neighbourhoods and in delivering recycling. Both public and private sector operators can deliver effective services in the appropriate situation; what matters more is a strong client organisation responsible for municipal solid waste management within the municipality, with stable political and financial backing and capacity to manage service delivery. Revenue collection is also integral to operator models: Generally the municipality pays the operator from direct charges and/or indirect taxes, rather than the operator collecting fees directly from the service user.

    As an abundant, renewable, domestic energy resource, biomass could help the United States reduce its dependence on imported oil. Biomass is the only renewable energy technology capable of addressing the national need for liquid transportation fuels. Thus, there is an incentive to develop economic conversion processes for converting biomass, including wood, into liquid fuels. Through research sponsored by the US DOE`s Biomass Thermochemical Conversion Program, the University of Arizona has developed a unique biomass direct liquefaction system. The system features a modified single-screw extruder capable of pumping solid slurries containing as high as 60 wt% wood flour in wood oil derived vacuum bottoms at pressures up to 3000 psi. The extruder-feeder has been integrated with a unique reactor by the University to form a system which offers potential for improving high pressure biomass direct liquefaction technology. The extruder-feeder acts simultaneously as both a feed preheater and a pumping device for injecting wood slurries into a high pressure reactor in the biomass liquefaction process. An experimental facility was constructed and following shakedown operations, wood crude oil was produced by mid-1985. By July 1988, a total of 57 experimental continuous biomass liquefaction runs were made using White Birch wood feedstock. Good operability was achieved at slurry feed rates up to 30 lb/hr, reactor pressures from 800 to 3000 psi and temperatures from 350{degree}C to 430{degree}C under conditions covering a range of carbon monoxide feed rates and sodium carbonate catalyst addition. Crude wood oils containing as little as 6--10 wt% residual oxygen were produced. 38 refs., 82 figs., 26 tabs.

    The first techniques of operative fracture with plates were developed in the 19th century. In fact, at the beginning these methods consisted of an open reduction of the fracture usually followed by a very unstable fixation. As a consequence, the fracture had to be opened with a real risk of (sometimes lethal) infection, and due to unstable fixation, protection with a cast was often necessary. During the period between World Wars I and II, plates for fracture fixation developed with great variety. It became increasingly recognised that, because a fracture of a long bone normally heals with minimal resorption at the bone ends, this may result in slight shortening and collapse, so a very rigid plate might prevent such collapse. However, as a consequence, delayed healing was observed unless the patient was lucky enough to have the plate break. One way of dealing with this was to use a slotted plate in which the screws could move axially, but the really important advance was recognition of the role of compression. After the first description of compression by Danis with a "coapteur", Bagby and Müller with the AO improved the technique of compression. The classic dynamic compression plates from the 1970s were the key to a very rigid fixation, leading to primary bone healing. Nevertheless, the use of strong plates resulted in delayed union and the osteoporosis, cancellous bone, comminution, and/or pathological bone resulted in some failures due to insufficient stability. Finally, new devices represented by locking plates increased the stability, contributing to the principles of a more biological osteosynthesis while giving enough stability to allow immediate full weight bearing in some patients.

    The impacts of mentoring in education have been well established. Mentors have a large impact on their mentees and have been show to affect mentee attitudes towards learning, interest in subjects, future success, and more. While mentoring has a well-documented impact on the mentees, mentoring also has an impact on the mentors themselves. However, little has been studied empirically about these impacts. When we looked for a validated instrument that measured the impact of mentoring on the scientists working with the teachers, we found many anecdotal reports but no instruments that meet our specific needs. To this end, we developed, tested, and implemented our own instrument for measuring the impacts of mentoring on our scientist mentors. Our instrument contained both quantitative and qualitative items designed to reveal the effects of mentoring in two areas: 1) cognitive domain (mentoring, teaching, understanding K-12) and 2) affective domain (professional, personal, participation). We first shared our survey with experts in survey development and mentoring, gathered their feedback, and incorporated their suggestions into our instrument. We then had a subsection of our mentors complete the survey and then complete it again three to four days later (test-retest). Our survey has a high correlation for the test-retest quantitative items (0.93) and a high correlation (0.90) between the three reviewers of the qualitative items. From our findings, we feel we have a validated instrument (face, content, and contruct validity) that answers our research questions reliably. Our contribution to the study of mentoring of science teachers reveals a broad range of impacts on the mentors themselves including an improved understanding of the challenges of classroom teaching, a recognition of the importance of scientists working with science teachers, an enhanced ability to communicate their research and findings, and an increased interest and excitement for their own work.

    This second part of a report for the International Energy Agency (IEA) made by Task 9 of the Photovoltaic Power Systems (PVPS) programme takes a look at the implementation of Solar Home Systems in developing countries. The objective of Task 9 is to increase the successful deployment of PV systems in developing countries. This summary outlines various models for the implementation of small domestic photovoltaic (PV) systems (Solar Home Systems, SHS) in developing countries. The first part of this two-part document discussed three generic models. Part 2 of the document is based on work prepared for the Renewable Energy Supply Models (RESUM) project. Examples are quoted which describe the operations of a number of companies supplying solar home systems in developing countries. These examples of practical experience provide a description of businesses, highlighting the success and failure factors of the organisations. They are only a sample of the many PV companies operating internationally and are not to be considered as a critical evaluation of the implementation models; they attempt to give the reader an idea of the realities of using the models in practice.

    The development and compounding of pharmacotherapeutic formulations that are suitable for infants and young children can be a challenging problem. This problem results from the lack of knowledge on the acceptability of different dosage forms and formulations to children in relation to age and developmental status, as well as the lack of reliable documentation of formulations used in pediatric clinical trials. As part of its mandate under the Best Pharmaceuticals for Children Act to improve pediatric therapeutics, the National Institute of Child Health and Human Development has sponsored the Pediatric Formulations Initiative. The goal of this ongoing initiative is to address the issues and concerns associated with pediatric therapeutics by convening groups of researchers and experts in pediatric formulations from academia, pharmaceutical companies, the National Institutes of Health, and the U.S. Food and Drug Administration. In this second part of a two-part article, the activities of the various groups that constitute the Pediatric Formulations Initiative are discussed, in addition the Initiative's future activities and plans are outlined.

    Part 1: Reverse-docking studies of a squaramide-catalyzed conjugate addition of a diketone to a nitro-olefin. Asymmetric organocatalysis, the catalysis of asymmetric reactions by small organic molecules, is a rapidly growing field within organic synthesis. The ability to rationally design organocatalysts is therefore of increasing interest to organic chemists. Computational chemistry is quickly proving to be an extremely successful method for understanding and predicting the roles of organocatalysts, and therefore is certain to be of use in the rational design of such catalysts. A methodology for reverse-docking flexible organocatalysts to rigid transition state models of asymmetric reactions has been previously developed by the Deslongchamps group. The investigation of Rawal's squaramide-based organocatalyst for the addition of a diketone to a nitro-olefin is described, and the results of the reverse docking of Rawal's catalyst to the geometry optimized transition state models of the uncatalyzed reaction for both the R and S-product enantiomers are presented. The results of this study indicate a preference for binding of the organocatalyst to the R-enantiomer transition state model with a predicted enantiomeric excess of 99%, which is consistent with the experimental results. A plausible geometric model of the transition state for the catalyzed reaction is also presented. The success of this study demonstrates the credibility of using reverse docking methods for the rational design of asymmetric organocatalysts. Part 2: The development of ChemSort: an educational game for organic chemistry. With the advent of the millennial learner, we need to rethink traditional classroom approaches to science learning in terms of goals, approaches, and assessments. Digital simulations and games hold much promise in support of this educational shift. Although the idea of using games for education is not a new one, well-designed computer-based "serious games" are only beginning to

    Full Text Available In phase 1 of a large multiyear effort, health communication and health promotion models were used to develop a comprehensive hearing loss prevention training program for carpenters. Additionally, a survey was designed to be used as an evaluation instrument. The models informed an iterative research process in which the authors used key informant interviews, focus groups, and early versions of the survey tool to identify critical issues expected to be relevant to the success of the hearing loss prevention training. Commonly held attitudes and beliefs associated with occupational noise exposure and hearing losses, as well as issues associated with the use or non-use of hearing protectors, were identified. The training program was then specifically constructed to positively shape attitudes, beliefs, and behavioral intentions associated with healthy hearing behaviors - especially those associated with appropriate hearing protector use. The goal was to directly address the key issues and overcome the barriers identified during the formative research phase. The survey was finalized using factor analysis methods and repeated pilot testing. It was designed to be used with the training as an evaluation tool and thus could indicate changes over time in attitudes, beliefs, and behavioral intentions regarding hearing loss prevention. Finally, the training program was fine tuned with industry participation so that its delivery would integrate seamlessly into the existing health and safety training provided to apprentice carpenters. In phase 2, reported elsewhere in this volume, the training program and the survey were tested through a demonstration project at two sites.

    Increasing political effort to improve water quality across the UK and Europe has led to water and sewerage companies investing heavily in high-tech wastewater treatment plants capable of producing high quality effluents. Consequently, amounts of bought-in electricity used for wastewater treatment has and will continue to increase significantly over coming years, while greater provision of enhanced sewage treatment also produces greater volumes of sewage sludge requiring treatment and disposal. Over the same period, tougher controls on the quality of biosolids applied to agricultural land have also been introduced, while there has been an international attempt to reduce the use of fossil-fuel derived power sources because of concerns over global warming. The latter has brought about the introduction of financial instruments, such as the Climate Change Levy, to curb energy use, promote energy efficiency and encourage the development of renewable energy technologies. These factors are set to drive-up the costs of providing adequate sewage treatment services, while at the same time, a tough regulatory line taken to control profits on regional monopolies held by the UK water companies will significantly reduce their revenues over the period 2000-05. The result is that, financially, UK water and sewerage companies face their most challenging period since privatisation in 1989. This paper briefly outlines the current regulations relating to water quality and energy use that will affect water company operations over coming years.

    The subject of the development of the WENDELSTEIN 7-X divertor is the manufacturing of approximately 900 plasma facing components (PFCs) that meet all requirements for reliable long pulse and long-term plasma operation. The actively cooled PFCs are made of CFC NB31 as plasma facing material bonded by Active Metal Casting (AMC) copper interlayer onto CuCrZr cooling structure. The pre-series activities integrated extensive high heat flux (HHF) testing to assess the industrial manufacturing. Tests were performed in the GLADIS facility under load conditions similar to those expected during operation of W7-X. The investigations focused on the improvement of fatigue resistance of the CFC/Cu bonding. The results of the last HHF test campaign demonstrated a significant enhancement of the CFC bonding quality due to the introduction of the AMC/Cu bi-layer technology. The results of the micro-chemical analyses (using EDX, AES, XPS and SIMS) of the CFC/Cu interface performed after 5000 cycles at 10 MW/m 2 confirmed its chemical stability. Far beyond the current available data about the expected lifetime of CFC-armoured PFCs, 10,000 cycles at 10 MW/m 2 were applied without any damages at the interface. The present design and manufacturing process of the tested PFCs fulfil all requirements for W7-X operation.

    Due to the existence of complexities of heterogeneities, hierarchy, discreteness, and interactions in municipal solid waste management (MSWM) systems such as Beijing, China, a series of socio-economic and eco-environmental problems may emerge or worsen and result in irredeemable damages in the following decades. Meanwhile, existing studies, especially ones focusing on MSWM in Beijing, could hardly reflect these complexities in system simulations and provide reliable decision support for management practices. Thus, a framework of distributed mixed-integer fuzzy hierarchical programming (DMIFHP) is developed in this study for MSWM under these complexities. Beijing is selected as a representative case. The Beijing MSWM system is comprehensively analyzed in many aspects such as socio-economic conditions, natural conditions, spatial heterogeneities, treatment facilities, and system complexities, building a solid foundation for system simulation and optimization. Correspondingly, the MSWM system in Beijing is discretized as 235 grids to reflect spatial heterogeneity. A DMIFHP model which is a nonlinear programming problem is constructed to parameterize the Beijing MSWM system. To enable scientific solving of it, a solution algorithm is proposed based on coupling of fuzzy programming and mixed-integer linear programming. Innovations and advantages of the DMIFHP framework are discussed. The optimal MSWM schemes and mechanism revelations will be discussed in another companion paper due to length limitation.

    The authors have developed a method of constructing high-density bentonite by means of wet spraying to act as a backfill material in narrow places in radioactive waste disposal facilities. On the basis of the results of laboratory tests, they conducted field spraying tests to investigate the field conditions. The results of these tests are summarized as follows: 1) The bentonite could be sprayed smoothly by using a rotary spraying machine and a screw conveyor. 2) Provided that the air flow was at least 18.5 m 3 /min and the nozzle diameter did not exceed 25 mm, an average dry density of bentonite of 1.6 Mg/m 3 or higher could be achieved. 3) The dry density was constant within the spraying distance range 500 mm ∼ 2000 mm. 4) With a nozzle diameter of 19 mm, a spraying distance of 1000 mm, and a water content of 19.5%, an average dry density of the sprayed bentonite of 1.6 Mg/m 3 or higher and a rebound ratio not exceeding 30% was achieved. 5) The dry density of the sprayed bentonite decreased as the volume of bentonite supplied was increased, and it was shows to be closely related to the rotational speed of the spraying machine and the volume of bentonite sprayed from each hole.

    Curcumin (CUR) is considered as one of the most bioactive molecules ever discovered from nature due to its proven anti-inflammatory and antioxidant in both preclinical and clinical studies. Despite its proven safety and efficacy, the clinical translation of CUR into a useful therapeutic agent is still limited due to its poor oral bioavailability. To overcome its limitation and enhance oral bioavailability by improving its aqueous solubility, stability, and intestinal permeability, a novel CUR formulation (NCF) was developed using the self-nanomicellizing solid dispersion strategy. From the initial screening of polymers for their potential to improve the solubility and stability, Soluplus (SOL) was selected. The optimized NCF demonstrated over 20,000-fold improvement in aqueous solubility as a result of amorphization, hydrogen bonding interaction, and micellization determined using differential scanning calorimetry, X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, nuclear magnetic resonance, dynamic light scattering, and transmission electron microscopy. Moreover, the greater stabilizing effect in alkaline pH and light was observed. Furthermore, significant enhancement of dissolution and permeability of CUR across everted sacs of rat small intestine were noticed. Pharmacokinetic studies demonstrated that the oral bioavailability of CUR was increased 117 and 17-fold in case of NCF and physical mixture of CUR and SOL compared to CUR suspension. These results suggest NCF identified as a promising new approach for repositioning of CUR for pharmaceutical application by enhancing the oral bioavailability of CUR. The findings herein stimulate further in vivo evaluations and clinical tests of NCF.

    Uncertainty of electrical efficiency measurement was investigated for a 10 kW-class SOFC system using town gas. Uncertainty of heating value measured by the gas chromatography method on a mole base was estimated as ±0.12% at 95% level of confidence. Micro-gas chromatography with/without CH 4 quantification may be able to reduce uncertainty of measurement. Calibration and uncertainty estimation methods are proposed for flow-rate measurement of town gas with thermal mass-flow meters or controllers. By adequate calibrations for flowmeters, flow rate of town gas or natural gas at 35 standard litters per minute can be measured within relative uncertainty ±1.0% at 95 % level of confidence. Uncertainty of power measurement can be as low as ±0.14% when a precise wattmeter is used and calibrated properly. It is clarified that electrical efficiency for non-pressurized 10 kW-class SOFC systems can be measured within ±1.0% relative uncertainty at 95% level of confidence with the developed techniques when the SOFC systems are operated relatively stably

    The owners of nuclear power plants should be demonstrate that the embrittlement effects by neutronic radiation do not commit the structural integrity from the pressure vessel of nuclear reactors, during conditions of routine operation and below postulate accident. For this reason, there are surveillance programs of vessels of nuclear power plants, in which are present surveillance capsules. A surveillance capsule is compound by the support, six containers for test tubes and dosimeters. The containers for test tubes are of two types: rectangular container for test tubes, Charpy V and Cylindrical Container for tension test tubes. These test tubes are subject to a same or bigger neutronic flow to that of vessel, being representative of vessel mechanical conditions. The test tubes are rehearsed to watch over the increase of embrittlement that presents the vessel. This work describes the development of welding system to seal the containers for test tubes, these should be filled with helium of ultra high purity, to a pressure of an atmosphere. In this system the welding process Gas Tungsten Arc Welding is used, a hermetic camera that allows to place the containers with three grades of freedom, a vacuum subsystem and pressure, high technology equipment's like: power source with integrated computer, arc starter of high frequency, helium flow controller, among others. Finally, the advances in the inspection system for the qualification of sealing system are mentioned, system that should measure the internal pressure of containers and the helium purity inside these.

    1980-01-01

    Recent developments of the Green's function method and the computer program SOUSSA (Steady, Oscillatory, and Unsteady Subsonic and Supersonic Aerodynamics) are reviewed and summarized. Applying the Green's function method to the fully unsteady (transient) potential equation yields an integro-differential-delay equation. With spatial discretization by the finite-element method, this equation is approximated by a set of differential-delay equations in time. Time solution by Laplace transform yields a matrix relating the velocity potential to the normal wash. Premultiplying and postmultiplying by the matrices relating generalized forces to the potential and the normal wash to the generalized coordinates one obtains the matrix of the generalized aerodynamic forces. The frequency and mode-shape dependence of this matrix makes the program SOUSSA useful for multiple frequency and repeated mode-shape evaluations.

    This report focuses on the model-building part of the PSO project, 'Control Conditions Bio-boiler'. In the project, which treats dynamic simulation of biomass fired power plants via the MMS software, a certain number of straw/wood chip modules have been built, together with a combustion module which, when connected to the existing MMS modules, can be used for dynamic simulation. Furthermore, a certain number of continuous and discrete components have been built which, together with the remaining MMS modules will create a complete model of the active part of the control structure under the most common operation conditions. By means of the developed straw, combustion and control modules, a model of Enstedvaerket's bio-boiler is built (without wood chip super-heater), including practically all auxiliary control mechanisms. In the report the primary problems caused by the development of the model are discussed, typically numerical problems. First of all it is discussed how a steady state condition can be reached from a nonphysical condition at the start-up of the simulation. After reaching a steady state condition at full load, the boiler load is reduced by adjusting the desired live steam flow setpoint value and the load gradient (as it would be done from the control room). While reducing to part load, one straw line is closed down, as it would be done in 'real life'. From part load, the boiler load is once again in the same way increased to full. (BA) The simulation results are then compared to measurements made on the same boiler during load reduction and load increase.

    With over a million median sternotomy surgeries performed worldwide every year, sternal wound complications have posed a serious risk to the affected patients. A rigid therapeutic sternal fixation device has therefore become a necessity. In this work, the incorporation of up to 0.5 mol% of tantalum pentoxide (Ta{sub 2}O{sub 5}), in exchange for zinc oxide (ZnO), into the SiO{sub 2}-ZnO-CaO-SrO-P{sub 2}O{sub 5} glass system is presented. The effect of Ta incorporation on the physical, chemical and biological properties of the glass polyalkenoate cements (GPCs) prepared from them have been presented in this manuscript. The data obtained have confirmed that Ta{sub 2}O{sub 5} incorporation into the reference glass system results in increased working times, radiopacity, ion solubility, and long-term mechanical stability. The formulated glass systems have also shown clear antibacterial and antifungal activity against both Gram-negative (Escherichia coli) and Gram-positive prokaryotes (Staphylococcus aureus and Streptococcus epidermidis), as well as eukaryotes (Fusarium solani). Cytotoxicity testing showed that Ta incorporation results in no toxicity effect and may simulate osseo-integration when tested in animal models. These new metallic-containing biomaterial adhesives have been developed for sternal fixation and repair. As a permanent implant, the formulated adhesives can be used in conjunction with sternal cable ties to offer optimal fixation for patients and reduce post-operative complications such as bacterial infection and pain from micro-motion. - Highlights: • Novel cements based on a tantalum-containing ionomer glass are presented. • The cements resulted in increased working times and long-term mechanical stability. • The cements exhibited both antibiotic and antimycotic activity. • The cements tested did not display any cytotoxic effects. • These cements have potential for sternal fixation and repair.

    A mutual climatic range method is applied to the Mediterranean marine pollen record of Semaforo (Vrica section, Calabria, Italy) covering the period from ∼2.46 Ma to ∼2.11 Ma. The method yields detailed information on summer, annual and winter temperatures and on precipitation during the nine obliquity and precession-controlled 'glacial' periods (marine isotope stages 96 to 80) and eight 'interglacial' periods (marine isotope stages 95 to 81) characterising this time interval. The reconstruction reveals higher temperatures of at least 2.8 °C in mean annual and 2.2 °C in winter temperatures, and 500 mm in precipitation during the 'interglacials' as compared to the present-day climate in the study area. During the 'glacials', temperatures are generally lower as compared to the present-day climate in the region, but precipitation is equivalent. Along the consecutive 'interglacials', a trend toward a reduction in annual and winter temperatures by more than 2.3 °C, and toward a higher seasonality is observed. Along the consecutive 'glacials', a trend toward a strong reduction in all temperature parameters of at least 1.6 °C is reconstructed. Climatic amplitudes of 'interglacial-glacial' transitions increase from the older to the younger cycles for summer and annual temperatures. The cross-spectral analyses suggest obliquity related warm/humid-cold/dry 'interglacial-glacial' cycles which are superimposed by precession related warm/dry- cold/humid cycles. A time displacement in the development of temperatures and precipitation is indicated for the obliquity band by temperatures generally leading precipitation change at ∼4 kyr, and on the precession band of ∼9.6 kyr in maximum.

  4. The Contribution of Professional Associations in Romania to the Prevention of Poverty and Exclusion by Developing Social Businesses. - Part II

    Full Text Available Global poverty is neither created by the poor, nor the result of any incapacity associated to them; instead, it is the outcome of the system built by all the people, the institutions they set up and the concepts they have formulated. In what follows we don’t want to suggest that Professional Associations would become philanthropic associations through the establishment and development of specific social economy foundations that concentrate their activity on poverty issues. Such associations have actually come to witness the problems mentioned above, namely the difficult situation of former employees from different areas; an example in this respect could be the massive and "the most successful privatization of all time" of oil companies, in 2004, when, by various subtle (compensatory means, the new capitalists have fired more than 40 thousand people, relegating them and their families to a life of poverty. Private oil companies have outsourced more services, which subsequently became the property of the capitalists managing them, at the expense of society, proving their clear interest in gaining significant profit. Therefore, Professional Associations in this area might become, among other things, active organizations within society, assuming a social role, for both their members from the oil industry and for non-members, for society at large. Professional associations promote the idea of a new form of capitalism and a new type of company (understood as a business, based on the generosity of people and defined by experts as "social business". The fundamental purpose: to eliminate the social, economic and environmental problems; reduce the consequences of many other problems in society, such as hunger, homelessness, disease, pollution, lack of education, which finally lead to national insecurity.

    To assess the reliability and validity of a hand motion sensor, Leap Motion Controller (LMC), in the 15-s hand grip-and-release test, as compared against human inspection of an external digital camera recording. Fifty healthy participants were asked to fully grip-and-release their dominant hand as rapidly as possible for two trials with a 10-min rest in-between, while wearing a non-metal wrist splint. Each test lasted for 15 s, and a digital camera was used to film the anterolateral side of the hand on the first test. Three assessors counted the frequency of grip-and-release (G-R) cycles independently and in a blinded fashion. The average mean of the three was compared with that measured by LMC using the Bland-Altman method. Test-retest reliability was examined by comparing the two 15-s tests. The mean number of G-R cycles recorded was: 47.8 ± 6.4 (test 1, video observer); 47.7 ± 6.5 (test 1, LMC); and 50.2 ± 6.5 (test 2, LMC). Bland-Altman indicated good agreement, with a low bias (0.15 cycles) and narrow limits of agreement. The ICC showed high inter-rater agreement and the coefficient of repeatability for the number of cycles was ±5.393, with a mean bias of 3.63. LMC appears to be valid and reliable in the 15-s grip-and-release test. This serves as a first step towards the development of an objective myelopathy assessment device and platform for the assessment of neuromotor hand function in general. Further assessment in a clinical setting and to gauge healthy benchmark values is warranted.

    them. The true flowering of medicine in B&H happening thanks to graduate doctors in Italy, Austria, Hungary, Turkey, etc. Through their action, in a short time, they greatly improved health in B&H, educated the population. The Franciscans were important because they opened the first open-air clinics, the first pharmacies, and wrote the first pharmacopoeia and regulations for the work of health care institutions. Numerous works preserved in monasteries have mostly brought about the study in only one or two copies. Their contribution to the development of health care and the prevention of illness and treatment of the population in B&H during that period is very significant.

    In the second stage of the research and development for a high-temperature helium-leak detection system, the temperature sensor using optical fibres was studied. The sensor detects the helium leakage by the temperature increase surrounded optical fibre with or without heat insulator. Moreover, the applicability of high temperature equipments as the HTTR system was studied. With the sensor we detected 5.0-20.0 cm{sup 3}/s helium leakages within 60 minutes. Also it was possible to detect earlier when the leakage level is at 20.0 cm {sup 3}/s. (author)

Creation of state system geriatric care as important part of state politics in the area of enhancement of quality of life was proved. General aspects of improvement of social support of disable elderly persons in condition of restricted budget and interagency separation was presented. Establishment of unified system of medical social support and gerotechnologies for the elderly was substantiated, as a mechanism facilitated life activity and decreasing of demographic loading on economic status of regions of Russian Federation. Legislative and normative regulations of gerontology and geriatric development were observed as well. Accepted legislative and normative acts were analyzed for period since 1977 to 2014. The necessity of approaches to regulation modernization for elderly was demonstrated. Analytical review on number of legislative state documents issued after meeting of Presidium of State Council of the Russian Federation being in August 2014 was also presented. Applicability of these documents for realization new strategy of gerontology and geriatrics development in Russia was proved.

    Fiber optic transmission is emerging as an attractive concept in data distribution onboard civil aircraft. Development of an Optical Data Distribution Network for Integrated Avionics and Control Systems for commercial aircraft will provide a data distribution network that gives freedom from EMI-RFI and ground loop problems, eliminates crosstalk and short circuits, provides protection and immunity from lightning induced transients and give a large bandwidth data transmission capability. In addition there is a potential for significantly reducing the weight and increasing the reliability over conventional data distribution networks. Wavelength Division Multiplexing (WDM) is a candidate method for data communication between the various avionic subsystems. With WDM all systems could conceptually communicate with each other without time sharing and requiring complicated coding schemes for each computer and subsystem to recognize a message. However, the state of the art of optical technology limits the application of fiber optics in advanced integrated avionics and control systems. Therefore, it is necessary to address the architecture for a fiber optics data distribution system for integrated avionics and control systems as well as develop prototype components and systems.

    CRIEPI developed a high speed simulation method to predict B scope images for crack-like defects under ultrasonic testing. This method is based on the geometrical theory of diffraction (GTD) to follow ultrasonic waves transmitted from the angle probe and with the aid of reciprocity relations to find analytical equations to express echoes received by the probe. The tip and mirror echoes from a slit with an arbitrary angle in the direction of thickness of test article and an arbitrary depth can be calculated by this method. Main object of the study is to develop a high speed simulation tool to gain B scope displays from the crack-like defect. This was achieved for the simple slits in geometry change regions by the prototype software based on the method. Fairy complete B scope images for slits could be obtained by about a minute on a current personal computer. The numerical predictions related to the surface opening slits were in excellent agreement with the relative experimental measurements. (author)

    This paper examines the potential for developing a more critical and reflexive curriculum around the sociology of health in nurse education. In Part One a review of the literature on Project 2000 to date suggests that insufficient attention has been paid to the scope for linking methodological and epistemological issues. it is argued that the status of 'andragogy' as a strategy of teaching and learning is ill-defined and that the nature of sociological theory in nurse education remains too crude and dichotomous to produce the 'knowledgeable doer', a qualitatively different kind of professional nurse practitioner.

  13. Developing of risk-hedging CO2-emission policy. Part II: risks associated with measures to limit emissions, synthesis and conclusions

    1996-01-01

    This paper is Part II of a two-part series in which the risk associated with unrestrained greenhouse-gas emissions, and with measures to limit emissions, are reviewed. The following risks associated with these efforts to limit CO 2 emissions are reviewed here: (1) resources might be diverted from other urgent needs; (2) economic growth might be reduced; (3) reduction measures might cost more than expected; (4) early action might cost more than later action; (5) reduction measures might have undesired side effects; (6) reduction measures might require heavy-handed government intervention; and (7) reduction measures might not work. With gradual implementation of a diversified portfolio of measures, these risks can be greatly reduced. Based on the review of risks associated with measures to limit emissions here, and the review of the risk associated with unrestrained emissions presented in Part I, it is concluded that a reasonable near-term (20-30 year) risk hedging strategy is one which seeks to stabilize global fossil CO 2 emissions at the present (early 1990s) level. This is turn implies an emission reduction of 26% for industrialized countries as a whole and 40-50% for Canada and the USA if developing country emissions are to increase by no more than 60%, which in itself would require major assistance from the industrialized countries. The framework and conclusions presented here are critically compared with so-called optimization frameworks. 82 refs., 2 figs., 2 tabs

Firstly, we have analyzed the same experiment that shoots a stream of bullets. In front of the gun we have a wall that has in it two holes just big enough to let a bullet through. Beyond the wall is a backstop (say a thick wall of wood which will absorb the bullets when they hit it. In this case, the probabilities just add together. The effect with both holes open is the sum of effects with each holes open alone. We have shown it for high school level. Next, we have analyzed a same experiment with water waves. The intensity observed when both holes are open is certainly not the sum of the intensity of the wave from hole 1 (which we find by measuring when hole 2 is blocked off and the intensity of the wave form hole 2 (seen when hole 1 is blocked. Finally, we have shown a software developed by students about double-slit experiment with bullets.

    An article in NASA Tech Briefs describing a vacuum bagging process for forming composite parts helped a small Oklahoma Company to improve its manufacturing process. President of Performance Extremes, Larry Ortega, and his partners make motorcycle parts from carbon/epoxy to reduce weight. Using vacuum bags, parts have a better surface and fewer voids inside. When heat used in the vacuum bag process caused deformation upon cooling, a solution found in another tech brief solved the problem. A metal plate inside the vacuum bag made for more even heat transfer. A third article described a simple procedure for repairing loose connector pins, which the company has also utilized.

    The objective of this study was to evaluate the efficacy of the developed investment for the prevention of blackening of a cast Type 4 gold and to analyze the oxides on its surface in relation to the blackening of the alloy. The experimental investments were prepared using a gypsum-bonded investment in which boron (B) or aluminum (Al) was added as a reducing agent. A Type 4 gold alloy was cast into the mold made of the prepared investment. The effect of the additives was evaluated from the color difference (deltaE*) between the as-cast surface and the polished surface of the cast specimen. B and Al were effective to prevent the blackening of a Type 4 gold alloy and the color of the as-cast surface approached that of the polished surface with increasing B and Al content. The prevention of the blackening of the gold alloy can be achieved by restraining the formation of CuO.

    The objective of this study is to develop a casting investment that prevents the blackening of the cast surface of noble metal alloys. The experimental investments were prepared using a gypsum-bonded investment in which the metallic powders such as boron (B), silicon (Si), aluminum (Al) and titanium (Ti) were added as oxidizing agents. An Ag-Pd-Cu-Au alloy was cast into the mold made of the prepared investment. The effect of the addition of each metal powder was evaluated from the color difference between the as-cast surface and the polished surface of the cast specimen. The color of the as-cast surface approached that of the polished surface with increasing B and Al content. A lower mean value in the color difference was obtained at 0.25-1.00 mass% B content. B and Al are useful as an additive in a gypsum-bonded investment to prevent the blackening of an Ag-Pd-Cu-Au alloy. The effects of Si and Ti powder addition could not be found.

    The development and compounding of pharmacotherapeutic formulations that are suitable for infants and young children can be a challenging problem. This problem results from the lack of knowledge on the acceptability of different dosage forms and formulations in children in relation to age and developmental status, as well as the lack of reliable documentation of formulations used in pediatric clinical trials. As part of its mandate under the Best Pharmaceuticals for Children Act to improve pediatric therapeutics, the National Institute of Child Health and Human Development has sponsored the Pediatric Formulation Initiative. The goal of this ongoing initiative is to address the issues and concnerns associated with pediatric therapeutics by convening groups of researchers and experts in pediatric formulations from academia, pharmaceutical companies, the National Institutes of Health, and the U.S. Food and Drug Administration.

    The technique of neutral buoyancy during water immersion was applied to a variety of questions pertaining to human performance factors in the early years of the space age. It was independently initiated by numerous aerospace contractors at nearly the same time, but specific applications depended on the problems that the developers were trying to solve. Those problems dealt primarily with human restraint and maneuverability and were often generic across extravehicular activity (EVA) and intravehicular activity (IVA) worksites. The same groups often also considered fractional gravity as well as weightless settings and experimented with ballasting to achieve lunar and Mars-equivalent loads as part of their on-going research and development. Dr. John Charles reviewed the association of those tasks with contemporary perceptions of the direction of NASA's future space exploration activities and with Air Force assessments of the military value of man in space.

    Due to the effects of climate change over the course of the next century, the combination of rising sea levels, severe storms, and coastal change will threaten the sustainability of coastal communities, development, and ecosystems as we know them today. To clearly identify coastal vulnerabilities and develop appropriate adaptation strategies due to projected increased levels of coastal flooding and erosion, coastal managers need local-scale hazards projections using the best available climate and coastal science. In collaboration with leading scientists world-wide, the USGS designed the Coastal Storm Modeling System (CoSMoS) to assess the coastal impacts of climate change for the California coast, including the combination of sea-level rise, storms, and coastal change. In this project, we directly address the needs of coastal resource managers in Southern California by integrating a vast range of global climate change projections in a thorough and comprehensive numerical modeling framework. In Part 1 of a two-part submission on CoSMoS, methods and the latest improvements are discussed, and an example of hazard projections is presented.

    To document the development of motor fusion when patients with a history of strabismic amblyopia are treated part-time with Bangerter foils. This was a prospective interventional outcome study of consecutive patients with a history of strabismic amblyopia, horizontal strabismus (only) ≤20(∆), visual acuity of 20/60 or better in the nonfixating eye, and no motor fusion (as indicated by the absence of prism vergence) for 1 year before entry into the study. Subjects wore a 0.1 density Bangerter foil for 3-4 hours daily. Data on visual acuity, alignment, and motor fusion status were collected for a minimum of 2 years. Patients with motor fusion were then followed for a minimum of 18 months to assess the stability of their motor fusion status after the Bangerter foil was discontinued. Of the 46 patients meeting entry criteria (mean age, 5.3 ± 1.7 years) who completed follow-up, 28 (61%) developed motor fusion. Motor fusion was retained in all 17 patients who were followed after their foils were discontinued for a mean of 13.3 months. A child's motor fusion status is generally believed to be established during an early formative period of visual development. The development of motor fusion in many of our patients during the course of part-time Bangerter foil treatment suggests that improvements in motor fusion status can occur at a later age than previously believed.

    As part of the preparation for the 1994 International Conference on Population and Development to be sponsored by the UN in Cairo, 6 expert groups were convened to consider 1) population growth; 2) population policies and programs; 3) population, development, and the environment; 4) migration; 5) the status of women; and 6) family planning programs, health, and family well-being. Each group included 15 experts representing a full range of relevant scientific disciplines and geographic regions. Each meeting lasted 5 days and included a substantive background paper prepared by the Population Division as well as technical papers. Each meeting concluded with the drafting of between 18 and 37 recommendations (a total of 162). The meeting on population, the environment, and development focused on the implications of current trends in population and the environment for sustained economic growth and sustainable development. The meeting on population policies and programs observed that, since 1984, there has been a growing convergence of views about population growth among the nations of the world and that the stabilization of world population as soon as possible is now an internationally recognized goal. The group on population and women identified practical steps that agencies could take to empower women in order to achieve beneficial effects on health, population trends, and development. The meeting on FP, health, and family well-being reviewed policy-oriented issues emerging from the experience of FP programs. The meeting on population growth and development reviewed trends and prospects of population growth and age structure and their consequences for global sustainability. The population distribution and migration experts appraised current trends and their interrelationship with development. In nearly all of the group meetings, common issues emerged. Concern was universally voiced for sustainable development and sustained economic growth, relevance of past experience

  4. Transport at basin scales: 1. Theoretical framework

    Directory of Open Access Journals (Sweden)

    A. Rinaldo

    2006-01-01

    Full Text Available The paper describes the theoretical framework for a class of general continuous models of the hydrologic response including both flow and transport of reactive solutes. The approach orders theoretical results appeared in disparate fields into a coherent theoretical framework for both hydrologic flow and transport. In this paper we focus on the Lagrangian description of the carrier hydrologic runoff and of the processes embedding catchment-scale generation and transport of matter carried by runoff. The former defines travel time distributions, while the latter defines lifetime distributions, here thought of as contact times between mobile and immobile phases. Contact times are assumed to control mass transfer in a well-mixed approximation, appropriate in cases, like in basin-scale transport phenomena, where the characteristic size of the injection areas is much larger than that of heterogeneous features. As a result, we define general mass-response functions of catchments which extend to transport of matter geomorphologic theories of the hydrologic response. A set of examples is provided to clarify the theoretical results towards a computational framework for generalized applications, described in a companion paper.

    For comprehensive usage of large geospatial meteorological and climate datasets it is necessary to create a distributed software infrastructure based on the spatial data infrastructure (SDI) approach. Currently, it is generally accepted that the development of client applications as integrated elements of such infrastructure should be based on the usage of modern web and GIS technologies. The paper describes the Web GIS for complex processing and visualization of geospatial (mainly in NetCDF and PostGIS formats) datasets as an integral part of the dedicated Virtual Research Environment for comprehensive study of ongoing and possible future climate change, and analysis of their implications, providing full information and computing support for the study of economic, political and social consequences of global climate change at the global and regional levels. The Web GIS consists of two basic software parts: 1. Server-side part representing PHP applications of the SDI geoportal and realizing the functionality of interaction with computational core backend, WMS/WFS/WPS cartographical services, as well as implementing an open API for browser-based client software. Being the secondary one, this part provides a limited set of procedures accessible via standard HTTP interface. 2. Front-end part representing Web GIS client developed according to a "single page application" technology based on JavaScript libraries OpenLayers (http://openlayers.org/), ExtJS (https://www.sencha.com/products/extjs), GeoExt (http://geoext.org/). It implements application business logic and provides intuitive user interface similar to the interface of such popular desktop GIS applications, as uDIG, QuantumGIS etc. Boundless/OpenGeo architecture was used as a basis for Web-GIS client development. According to general INSPIRE requirements to data visualization Web GIS provides such standard functionality as data overview, image navigation, scrolling, scaling and graphical overlay, displaying map

    This work presents two research efforts, one involving planetary science education research and a second involving the surface composition of Mars. In the former, student beliefs and reasoning difficulties associated with the greenhouse effect were elicited through student interviews and written survey responses from >900 US undergraduate non-science majors. This guided the development of the Greenhouse Effect Concept Inventory (GECI), an educational research tool designed to assess pre- and post-instruction conceptual understanding of the greenhouse effect. Three versions of this multiple-choice instrument were administered to >2,500 undergraduates as part of the development and validation process. In contrast to previous research efforts regarding causes, consequences, and solutions to the enhanced greenhouse effect, the GECI focuses primarily on the physics of energy flow through Earth's atmosphere. The GECI is offered to the science education community as a research tool for assessing instructional strategies on this topic. It was confirmed that the study population subscribes to several previously identified beliefs. These include correct understandings that carbon dioxide is an important greenhouse gas and the greenhouse effect increases planetary surface temperatures. Students also commonly associate the greenhouse effect with increased penetration of sunlight into and trapping of solar energy in the atmosphere. Students intermix concepts associated with the greenhouse effect, global warming, and ozone depletion. Reinforcing the latter concept, a majority believe that the Sun radiates most of its energy as ultraviolet light. Students also describe inaccurate and incomplete trapping models, which include permanent trapping, trapping through reflection, and trapping of gases and pollution. Another reasoning difficulty involves the idea that Earth's surface radiates energy primarily during the nighttime. The second research effort describes the distribution of

    In the German-speaking part of Europe research in the pediatric field has been dominated by research with a biomedical focus. Nursing research investigating and evaluating the treatment and care process in the pediatric field has been marginal and, in the last decades, provided little evidence to enhance the development of specific criteria for nursing sensitive outcomes in this patient population. This fact is all the more problematic as the linear transfer of evidence from nursing research in the adult care setting is not feasible, i.e. the pediatric population has unique needs which are different from those of adults. Given that 22% of the Swiss population are children and adolescents up to 19 years, there is an urgent need for developing interdisciplinary nursing research projects in order to promote research which is oriented towards a bio-psychosocial model. Such research will provide the evidence needed to enhance the general well-being of children and adolescents with acute and chronic diseases as well as the well-being of their parents. To date, there has been no nursing research agenda based on the literature and on expert opinion in the pediatric field in Switzerland. This report aims to bridge this gap: it presents suggestions for a nursing research agenda in the pediatric field for the time from 2007 to 2017. Three research priorities emerged from the development process of the present agenda: 1) Evaluation of the effectiveness of nursing interventions, 2) Conceptualization and evaluation of practical impacts of family systems on the treatment process of children, 3) Research-based development of new nursing care services in a changing health care system. This report was developed in the context of the national project, "Swiss Research Agenda for Nursing". The presented agenda can be used as a basis for discussions on the strategic direction and for the development of an action plan to promote nursing research in the pediatric field in Switzerland.

    In this study, the maintenance process by the servo manipulator for the parts of the equipment that cannot be reached by MSM in the hot cell was developed. To do this, the virtual mock up is implemented using virtual prototyping technology. And, Using this mock-up, the workspace of the manipulators in the hot cell and the operator's view through the wall-mounted lead glass are analyzed. And the path planning of the servo manipulator using the collision detection of the virtual mockup is established. Also, the maintenance process for the parts of the equipment that are located out area of the MSM's workspace by the servo manipulator is proposed and verified through the graphic simulation. The proposed remote maintenance process of the equipment can be effectively used in the real hot cell operation. Also, the implemented virtual mock-up of the hot cell can be effecively used in analyzing the various hot cell operation and in enhancing the reliability and safety of the spent fuel manaement

    2010-01-01

    This paper is the last in a series of six papers that have described different aspects of mentoring. It considers the impact of mentoring when it is used in general dental practice, applying the technique of learning through positive psychology. The first part of the paper considers this approach from a patient's perspective, the second from the perspective of a dentist. Because the impact on the quality of care for the patient is largely mediated through the personality of the dentist, the quality of the dentist's own performance, during his/her professional relationship with the patient, is a critical ingredient. The way that this critical ingredient impacts on quality of care is considered and parallels are drawn between roles assumed in dental practice and those found in industry. The paper also considers the way in which mentoring, as a part of a professional development programme, can enhance dentists' personal skills and performance. It is an opportunity for great personal growth, with increased levels of job and life satisfaction, leading to greater levels of authentic happiness for all those involved, not least for dentists and the dental team.

    The goals of environmental legislation and associated regulations are to protect public health, natural resources, and ecosystems. In this context, monitoring programs should provide timely and relevant information so that the regulatory community can implement legislation in a cost-effective and efficient manner. The Safe Drinking Water Act (SDWA) of 1974 attempts to ensure that public water systems (PWSs) supply safe water to its consumers. As is the case with many other federal environmental statutes, SDWA monitoring has been implemented in relatively uniform fashion across the United States. In this three part series, spatial and temporal patterns in water quality data are utilized to develop, compare, and evaluate the economic performance of alternative place-based monitoring approaches to current monitoring practice. Part II: Several factors affect the performance of monitoring strategies, including: measurable objectives, required precision in estimates, acceptable confidence levels of such estimates, available budget for sampling. In this paper, we develop place-based monitoring strategies based on extensive analysis of available historical water quality data (1960-1994) of 19 Iowa community water systems. These systems supply potable water to over 350,000 people. In the context of drinking water, the objective is to protect public health by utilizing monitoring resources to characterize contaminants that are detectable, and are close to exceeding health standards. A place-based monitoring strategy was developed in which contaminants were selected based on their historical occurrence, rather than their appearance on the SDWA contaminant list. In a subset of the water systems, the temporal frequency of monitoring for one ubiquitous contaminant, nitrate, was tailored to patterns in its historical occurrence and concentration. Three sampling allocation models (linear, quadratic, and cubic) based on historic patterns in peak occurrence were developed and

    This article describes a systematic process of geographic and strategic planning for healthcare services as a part of a regional development plan in the Israeli Galilee. The planning process consisted of three stages: (a) assessment of needs, demand and existing resources; (b) prioritisation of initiatives; and (c) scheduling of theoretical priorities. For many years the region has suffered from inequities and inequalities regarding the availability and accessibility of a regional healthcare system, resulting in high mortality and morbidity rates and low quality of life. The aim of the healthcare strategic plan was to suggest initiatives and actions to be taken in order to improve healthcare provision and the health and wellbeing of local residents.

    Documentation of the preliminary software developed as a framework for a generalized integrated robotic system simulation is presented. The program structure is composed of three major functions controlled by a program executive. The three major functions are: system definition, analysis tools, and post processing. The system definition function handles user input of system parameters and definition of the manipulator configuration. The analysis tools function handles the computational requirements of the program. The post processing function allows for more detailed study of the results of analysis tool function executions. Also documented is the manipulator joint model software to be used as the basis of the manipulator simulation which will be part of the analysis tools capability.

    reproducible so that predictions can be made, with reasonable confidence, that there is a low level of probability of there being a viable microorganism present on product after sterilization. Specification of this probability is a matter for regulatory authorities and may vary from country to country (see, for example, EN 556-1 and ANSI/AAMI ST67). Generic requirements of the quality management system for design and development, production, installation and servicing are given in ISO 9001 and particular requirements for quality management systems for medical device production are given in ISO 13485. The standards for quality management systems recognise that, for certain processes used in manufacturing, the effectiveness of the process cannot be fully verified by subsequent inspection and testing of the product. Sterilization is an example of such a process. For this reason, sterilization processes are validated for use, the performance of the sterilization process is monitored routinely and the equipment is maintained. Exposure to a properly validated, accurately controlled sterilization process is not the only factor associated with the provision of reliable assurance that the products are sterile and, in this regard, suitable for its intended use. Attention is therefore given to a number of considerations including: a) the microbiological status of incoming raw materials and/or components; b) the validation and routine control of any cleaning and disinfection procedures used on the product; c) the control of the environment in which the product is manufactured, assembled and packaged; d) the control of equipment and processes; e) the control of personnel and their hygiene; f) the manner and materials in which the product is packaged; g) the conditions under which product is stored. This part of ISO 11137 describes the requirements for ensuring that the activities associated with the process of radiation sterilization are performed properly. These activities are described

    Highlights: • A 1D model of a solenoid common-rail ballistic injector is implemented in AMESim. • A detailed dimensional and a hydraulic characterization lead to a fair validation. • Fuel temperature influence on injector dynamics is assessed through 1D simulations. • Temperature impacts through changes in inlet orifice regime and viscous friction. • Cold fuel temperature leads to a slower injection opening due to high viscosity. - Abstract: A one-dimensional model of a solenoid-driven common-rail diesel injector has been developed in order to study the influence of fuel temperature on the injection process. The model has been implemented after a thorough characterization of the injector, both from the dimensional and the hydraulic point of view. In this sense, experimental tools for the determination of the geometry of the injector lines and orifices have been described in the paper, together with the hydraulic setup introduced to characterize the flow behaviour through the calibrated orifices. An extensive validation of the model has been performed by comparing the modelled mass flow rate against the experimental results introduced in the first part of the paper, which were performed for different engine-like operating conditions involving a wide range of fuel temperatures, injection pressures and energizing times. In that first part of the study, an important influence of the fuel temperature was reported, especially in terms of the dynamic behaviour of the injector, due to its ballistic nature. The results from the model have allowed to explain and further extend the findings of the experimental study by analyzing key features of the injector dynamics, such as the pressure drop established in the control volume due to the control orifices performance or the forces due to viscous friction, also assessing their influence on the needle lift laws.

    Regulating the environmental discharge of 220 Rn (historically known as thoron) and its decay products from thorium processing facilities is important for protection of environment and general public living in the vicinities. Activated charcoal provides an effective solution to this problem because of its high adsorption capacity to gaseous element like radon. In order to design and develop a charcoal based Thoron Mitigation System, a mathematical model has been developed in the present work for studying the 220 Rn transport and adsorption in a flow through charcoal bed and estimating the 220 Rn mitigation factor (MF) as a function of system and operating parameters. The model accounts for inter- and intra-grain diffusion, advection, radioactive decay and adsorption processes. Also, the effects of large void fluctuation and wall channeling on the mitigation factor have been included through a statistical model. Closed form solution has been provided for the MF in terms of adsorption coefficient, system dimensions, grain size, flow rate and void fluctuation exponent. It is shown that the delay effects due to intra grain diffusion plays a significant role thereby rendering external equilibrium assumptions unsuitable. Also, the application of the statistical model clearly demonstrates the transition from the exponential MF to a power-law form and shows how the occurrence of channels with low probability can lower mitigation factor by several orders of magnitude. As a part of aiding design, the model is further extended to optimise the bed dimensions in respect of pressure drop and MF. The application of the results for the design and development of a practically useful charcoal bed is discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Thermodynamic data for compounds and complexes of elements with auxiliary species specialized in modeling requirements for safety assessments of radioactive waste disposal systems have been developed by the Thermochemical Data Base (TDB) project of the Nuclear Energy Agency in the Organization for Economic Co-operation and Development (OECD/NEA). Recently, thermodynamic data for aqueous complexes, solids and gases of thorium, tin and iron (Part 1) have been published in 2008, 2012 and 2013, respectively. These thermodynamic data have been selected on the basis of NEA’s guidelines which describe peer review and data selection, extrapolation to zero ionic strength, assignment of uncertainty, and temperature correction; therefore the selected data are considered to be reliable. The reliability of selected thermodynamic data of TDB developed by Japan Atomic Energy Agency (JAEA-TDB) has been confirmed by comparing with selected data by the NEA. For this comparison, text files of the selected data on some geochemical calculation programs are required. In the present report, the database files for the NEA’s TDB with addition of selected data for iron, tin and thorium to the previous files have been established for use of PHREEQC, Geochemist’s Workbench and EQ3/6. In addition, as an example of confirmation of quality, dominant species in iron TDB were compared in Eh-pH diagram and differences between JAEA-TDB and NEA-TDB were shown. Data base files established in the present study will be at the Website of thermodynamic, sorption and diffusion database in JAEA (http://migrationdb.jaea.go.jp/). A CD-ROM is attached as an appendix. (J.P.N.)

    1986-01-01

    A rain attenuation prediction model is described for use in calculating satellite communication link availability for any specific location in the world that is characterized by an extended record of rainfall. Such a formalism is necessary for the accurate assessment of such availability predictions in the case of the small user-terminal concept of the Advanced Communication Technology Satellite (ACTS) Project. The model employs the theory of extreme value statistics to generate the necessary statistical rainrate parameters from rain data in the form compiled by the National Weather Service. These location dependent rain statistics are then applied to a rain attenuation model to obtain a yearly prediction of the occurrence of attenuation on any satellite link at that location. The predictions of this model are compared to those of the Crane Two-Component Rain Model and some empirical data and found to be very good. The model is then used to calculate rain attenuation statistics at 59 locations in the United States (including Alaska and Hawaii) for the 20 GHz downlinks and 30 GHz uplinks of the proposed ACTS system. The flexibility of this modeling formalism is such that it allows a complete and unified treatment of the temporal aspects of rain attenuation that leads to the design of an optimum stochastic power control algorithm, the purpose of which is to efficiently counter such rain fades on a satellite link.

    Due to demographic changes, the employee structure in companies is changing dramatically. It will be necessary to offer employees suitable, age-adequate jobs. As one of its foremost goals, optimized business management strategies must create conditions for guaranteeing a person’s health, work ability, and work motivation. In the context of corporate age management concepts, the literature recommends to retain and integrate older employees in the organization. This paper aims at developing an extended model of the relation between work motivation and health as affected by work ability and at deriving a host of measures that enterprises can apply as part of a corporate age management policy to counteract the impact of demographic changes. The model also takes into consideration factors influencing the relation between work motivation and health as affected by work ability (socio-demographic parameters, occupation, work-related stress). Additionally, the extended model translates the literature-based results into a corporate setting by way of a corporate age management program. The model comprises a process focusing on retaining and promoting work ability in order to maintain or boost work motivation and health. The host of measures presented serves as a basis to preventively counter demographic change on an individual, interpersonal, and structural level.

    The safety protection sequence panel of HTTR is a control panel to actuate an engineering safety system for protecting the reactor core, reactor coolant pressure boundary, and containment vessel boundary at the time of an accident of the nuclear reactor facilities. The safety code stipulates that the control panel should receive safety check at a frequency of once a month during reactor operation. When abnormality has been found, it is required to eliminate its causes and restore normal operation as soon as possible. However, since this control panel is composed of a complex control circuit, the cause check during abnormality requires the confirmation by a knowledgeable person spending quite a lot of time for chart checking, which leads to a delay of restoration. To achieve a rapid restoration, the abnormal part assignment system (APAS), which can specify abnormality instantaneously even by a common operator, was developed. It has been confirmed that with this system, rapid initial response and prompt restoration can be effectively made. (A.O.)

    With an estimated backlog of 4,000,000 patients worldwide, cleft lip and cleft palate remain a stark example of the global burden of surgical disease. The need for a new paradigm in global surgery has been increasingly recognized by governments, funding agencies, and professionals to exponentially expand care while emphasizing safety and quality. This three-part article examines the evolution of the Operation Smile Guwahati Comprehensive Cleft Care Center (GCCCC) as an innovative model for sustainable cleft care in the developing world. The GCCCC is the result of a unique public-private partnership between government, charity, and private enterprise. In 2009, Operation Smile, the Government of Assam, the National Rural Health Mission, and the Tata Group joined together to work towards the common goal of creating a center of excellence in cleft care for the region. This partnership combined expertise in medical care and training, organizational structure and management, local health care infrastructure, and finance. A state-of-the-art surgical facility was constructed in Guwahati, Assam which includes a modern integrated operating suite with an open layout, advanced surgical equipment, sophisticated anesthesia and monitoring capabilities, central medical gases, and sterilization facilities. The combination of established leaders and dreamers from different arenas combined to create a synergy of ambitions, resources, and compassion that became the backbone of success in Guwahati.

    2003-01-01

    Full Text Available Kinetic and mechanistic data relevant to the tropospheric degradation of aromatic volatile organic compounds (VOC have been used to define a mechanism development protocol, which has been used to construct degradation schemes for 18 aromatic VOC as part of version 3 of the Master Chemical Mechanism (MCM v3. This is complementary to the treatment of 107 non-aromatic VOC, presented in a companion paper. The protocol is divided into a series of subsections describing initiation reactions, the degradation chemistry to first generation products via a number of competitive routes, and the further degradation of first and subsequent generation products. Emphasis is placed on describing where the treatment differs from that applied to the non-aromatic VOC. The protocol is based on work available in the open literature up to the beginning of 2001, and some other studies known by the authors which were under review at the time. Photochemical Ozone Creation Potentials (POCP have been calculated for the 18 aromatic VOC in MCM v3 for idealised conditions appropriate to north-west Europe, using a photochemical trajectory model. The POCP values provide a measure of the relative ozone forming abilities of the VOC. These show distinct differences from POCP values calculated previously for the aromatics, using earlier versions of the MCM, and reasons for these differences are discussed.

    This paper, part one of a two paper report, describes key aspects of the research context of an ongoing practice development project, conducted on two UK sites. The paper begins with a discussion of the project's origins within a community of people working in the recovery paradigm, including the contributory strand of the first author's recovery and survivor writing. The discussion then turns to three inter-related areas within which the research component sits and which provide it with philosophical, theoretical and conceptual coherence. Each area will be unpacked and its significance explained. This will provide a platform for discussing the focus, methodology and methods of the research, and related assumptions governing both data collection and analysis. The paper concludes with a research commitment to a mental health nursing practice allied to recovery as narrative healing.

    The results of surveys conducted in the eastern part of Obanazawa region, Yamagata Prefecture, in fiscal 1988-1989 are compiled in this report. Conducted were a geological/alteration zone survey, geochemical survey, electromagnetic surveillance (TDEM - time domain electromagnetic method), gravity prospecting (review of gravity data), electric prospecting (Schlumberger method), heat flow rate survey, test boring, environmental impact survey, and so forth. Conclusions are mentioned below. It is inferred that the water of the Ginzan hot spring of the neutral Cl-SO{sub 4} type originates in meteoric water in mountains high above the mean sea level in the western side and that the hot spring water is produced when water heated to approximately 170 degrees C at a depth (1,500-2,000 meters below mean sea level) in the Ginzan hot spring district, where the ground temperature is the highest in this region, is diluted by groundwater near the surface at its ultimate stage of ascent. The survey results disclose that possibilities are quite low that a high-temperature sector of 200 degrees C or higher is found at a level not deeper than 2,000 meters from the ground surface. Accordingly, no geothermal development by flash steam power generation is feasible at the present stage at any economically acceptable depth. (NEDO)

  11. Palatal development of preterm and low birthweight infants compared to term infants – What do we know? Part 2: The palate of the preterm/low birthweight infant

    Full Text Available Abstract Background Well-designed clinical studies on the palatal development in preterm and low birthweight infants are desirable because the literature is characterized by contradictory results. It could be shown that knowledge about 'normal' palatal development is still weak as well (Part 1. The objective of this review is therefore to contribute a fundamental analysis of methodologies, confounding factors, and outcomes of studies on palatal development in preterm and low birthweight infants. Methods An electronic literature search as well as hand searches were performed based on Cochrane search strategies including sources of more than a century in English, German, and French. Original data were recalculated from studies which primarily dealt with both preterm and term infants. The extracted data, especially those from non-English paper sources, were provided unfiltered for comparison. Results Seventy-eight out of 155 included articles were analyzed for palatal morphology of preterm infants. Intubation, feeding tubes, feeding mode, tube characteristics, restriction of oral functions, kind of diet, cranial form and birthweight were seen as causes contributing to altered palatal morphology. Changes associated with intubation concern length, depth, width, asymmetry, crossbite, and contour of the palate. The phenomenon 'grooving' has also been described as a complication associated with oral intubation. However, this phenomenon suffers from lack of a clear-cut definition. Head flattening, pressure from the oral tube, pathologic or impaired tongue function, and broadening of the alveolar ridges adjacent to the tube have been raised as causes of 'grooving'. Metrically, the palates of intubated preterm infants remain narrower, which has been examined up to the age of the late mixed dentition. Conclusion There is no evidence that would justify the exclusion of any of the raised causes contributing to palatal alteration. Thus, early orthodontic and

    The publication is the second part of the analytical review on the new stage of development of gerontology and geriatrics in Russia. Components of social support system for senior citizens and the structure of social-medical care as its crucial components are presented. The problem of positioning of geriatric care within the system of social support for senior citizens, as well as its peculiarities and the algorithm providing geriatric care are discussed. The analysis of this algorithm allowed us to justify the indissoluble link and continuity of individual components of geriatric care and its cost-effectiveness. The position of the Russian Federation Ministry of Health concerning of introduction of geriatric care as an element in the system of medical care for older citizens was looking through. The pilot project «Territory of Care» proposed by the Russian Federation Ministry of Labor and Ministry of Health for establishment of long-term system of medical and social care to citizens of the older generation on the principles of multidisciplinary and interdepartmental interaction was elucidated as well. Some failures of the project have been highlighted and recommendations for its development were stressed. The role of gerontology as a systemic basis for creation of geriatric service in Russia and for the development of an integrated social and medical care to citizens of the older generation was underlined. The main priorities in the field of aging in the forthcoming decade are formulated. The most promising areas of research in the field of gerontology were discussed, the implementation of which will allow to realize the State social policy goals focused on the quality of life of senior citizens. Finally, the position of Gerontological Society of the Russian Academy of Sciences on the creation of mechanisms of scientific support for the renovation of geriatric services, including collaboration with experts in the field of practical medicine, social workers, and

  13. Challenges and Recent Developments in Hearing Aids: Part II. Feedback and Occlusion Effect Reduction Strategies, Laser Shell Manufacturing Processes, and Other Signal Processing Technologies

    2004-01-01

    This is the second part of a review on the challenges and recent developments in hearing aids. Feedback and the occlusion effect pose great challenges in hearing aid design and usage. Yet, conventional solutions to feedback and the occlusion effect often create a dilemma: the solution to one often leads to the other. This review discusses the advanced signal processing strategies to reduce feedback and some new approaches to reduce the occlusion effect. Specifically, the causes of three types of feedback (acoustic, mechanical, and electromagnetic) are discussed. The strategies currently used to reduce acoustic feedback (i.e., adaptive feedback reduction algorithms using adaptive gain reduction, notch filtering, and phase cancellation strategies) and the design of new receivers that are built to reduce mechanical and electromagnetic feedback are explained. In addition, various new strategies (i.e., redesigned sound delivery devices and receiver-in-the-ear-canal hearing aid configuration) to reduce the occlusion effect are reviewed. Many manufacturers have recently adopted laser shell-manufacturing technologies to overcome problems associated with manufacturing custom hearing aid shells. The mechanisms of selected laser sintering and stereo lithographic apparatus and the properties of custom shells produced by these two processes are reviewed. Further, various new developments in hearing aid transducers, telecoils, channel-free amplification, open-platform programming options, rechargeable hearing aids, ear-level frequency modulated (FM) receivers, wireless Bluetooth FM systems, and wireless programming options are briefly explained and discussed. Finally, the applications of advanced hearing aid technologies to enhance other devices such as cochlear implants, hearing protectors, and cellular phones are discussed. PMID:15735871

    A thesis in two independent halves. Part I. A search for the exclusive semileptonic decay modes D + → bar K ππ + ν e and D + → bar K * πe + ν e are presented using data from the Fermi-lab photoproduction experiment E691. With good sensitivity, the author observes no signals in the channels D + → K - π + π degrees e + ν e and D + → bar K degrees π + π - e + ν e , and set upper limits that represent only a small fraction of the inclusive semileptonic branching ration. The experiment was conducted at the Fermi-lab tagged Photon Laboratory, using a large acceptance spectrometer with silicon microvertex detector to extract a large, clean charm sample. Part II. The physics, design, and results of the Stanford Large Detector (SLD) Cherenkov Ring Imaging Detector (CRID) are described. The physics motivation and performance for the SLD CRID, the principles of Cherenkov detection, and a description of the SLD CRID are combined with a detailed description of the production and testing of the mirrors. In addition, results from the engineering run and cosmic ray tests demonstrate the current status of the system

    Full Text Available The value chain represents a detailed outline of the process that a product or service passes from raw materials, production and distribution to the consumer. The aim of this article is that within the analyzed companies in the area of the statistical region of South Serbia determined the dynamics of purchasing and marketing of non-wood forest products (NWFPs, and their value. The purpose of this research is to examine the possibilities for the development of small and medium-sized enterprises (SMEs towards sustainable use of NWFPs in a part of the territory of South Serbia. The subjects of the research are: purchased and sold quantities in analyzed companies, as well as the prices of these products in the market. The research was conducted in the territory of the dominant Pcinja, and they included 19 companies engaged in purchasing, processing and sale of NTFPs. The purchase of forest raspberries, wild strawberries and blackberries and herbs is represented within the Pcinja District. The highest average annual growth rates were recorded in the sales of products with added value of dog rose (Rosa canina and cornelian (Cornus mas. Export oriented enterprises in this area are at a low level. The total gross revenue earned by the placement of the selected final NWFPs in the domestic market was about 6,315,710 €.

    Nazeer M. Asmael

    2015-07-01

    Full Text Available In developing countries such as Syria, the lack of hydrological data affects groundwater resource assessment. Groundwater models provide the means to fill the gaps in the available data in order to improve the understanding of groundwater systems. The study area can be considered as the main recharge area of the eastern side of Barada and Awaj basin in the eastern part of Mt. Hermon. The withdrawal for agricultural and domestic purposes removes a considerable amount of water. The steady-state three-dimensional (3D groundwater model (FEFLOW which is an advanced finite element groundwater flow and transport modeling tool, was used to quantify groundwater budget components by using all available data of hydrological year 2009–2010. The results obtained may be considered as an essential tool for groundwater management options in the study area. The calibrated model demonstrates a good agreement between the observed and simulated hydraulic head. The result of the sensitivity analysis shows that the model is highly sensitive to hydraulic conductivity changes and sensitive to a lesser extent to water recharge amount. Regarding the upper aquifer horizon, the water budget under steady-state condition indicates that the lateral groundwater inflow from the Jurassic aquifer into this horizon is the most important recharge component. The major discharge component from this aquifer horizon occurs at its eastern boundary toward the outside of the model domain. The model was able to produce a satisfying estimation of the preliminary water budget of the upper aquifer horizon which indicates a positive imbalance of 4.6 Mm3·y−1.

    Raisch, D W

    1990-04-01

    The purpose of this literature review is to develop a model of methods to be used to influence prescribing. Four bodies of literature were identified as being important for developing the model: (1) Theoretical prescribing models furnish information concerning factors that affect prescribing and how prescribing decisions are made. (2) Theories of persuasion provide insight into important components of educational communications. (3) Research articles of programs to improve prescribing identify types of programs that have been found to be successful. (4) Theories of human inference describe how judgments are formulated and identify errors in judgment that can play a role in prescribing. This review is presented in two parts. This article reviews prescribing models, theories of persuasion, studies of administrative programs to control prescribing, and sub-optimally designed studies of educational efforts to influence drug prescribing.

  19. Development of methods for evaluation of electricity saving and load levelling measures. Part 2: The planning and implementation of a power conservation campaign

    Energy Technology Data Exchange (ETDEWEB)

    Storm Soerensen, M.; Madsen, P.K. [NESA A/S, Research and Development Dept. (Denmark)

    1997-12-01

    In recent years many campaigns and projects have been carried out with the purpose of reducing the energy consumption. Simultaneously a lot of economic and structural changes are taking place in society in general; changes which also affect the size of the electricity consumption. Furthermore, there is a trend towards increased use of wind mills and decentral combined heating and power plants, which affects the electricity load of the local area. It is difficult to identify and separate the effect of each of these attitude-adjusting activities. The project `Development of methods for evaluation of the effect of electricity saving and load levelling measures` focuses on two different methods which, on different levels, can be used to determine the impact of different different activities on the electricity consumption. Both methods are based on mathematical statistics, and they consist of an analysis of historical data and a test campaign which will make it possible to test specific activities in a comparatively small scale. The historical part covers the years 1974 to 1994 and include such variables as: demography, economic factors, climatic conditions, periods of electricity saving campaigns, the start of billing according to time of day tariff etc. The wish to be able to measure the extent of these energy saving and load reducing initiatives resulted in a test campaign which was carried out under very restricted conditions starting in the fall of 1996. If the effect of the test campaign can be measured and as a consequence of this a method can be estimated, it will be possible to place models which can measure the effect of future campaigns. The primary object of the campaign is not the size of the electricity savings of the individual customer, but rather to obtain total savings for the entire group of customers. The test has been structured in a way which makes it possible to perform an analysis of the effect of the campaign by use of analysis of intervention
