    A majority of states have now enacted legislation addressing the issue of joint custody of children after divorce. This article examines current research on the subject, explores its implications for family theory, and attempts to draw some empirically based conclusions regarding policy. The literature would seem to support a structuralist view of the family and to undermine normative theories of the family life cycle. The author concludes that policy should not be aimed at developing a presumption of joint legal custody alone, but, rather, of joint physical custody with specified limitations.

    1999-09-01

    U.S. Department of Energy (DOE) Cooperative Agreement DE-FC21-93MC30098 funded through the Office of Fossil Energy and administered at the Federal Energy Technology Center (FETC) supported the performance of a Jointly Sponsored Research Program (JSRP) at the Energy and Environmental Research Center (EERC) with a minimum 50% nonfederal cost share to assist industry in commercializing and effectively applying efficient, nonpolluting energy technologies that can compete effectively in meeting market demands for clean fuels, chemical feedstocks, and electricity in the 21st century. The objective of the JSRP was to advance the deployment of advanced technologies for improving energy efficiency and environmental performance through jointly sponsored research on topics that would not be adequately addressed by the private sector alone. Examples of such topics include the barriers to hot-gas cleaning impeding the deployment of high-efficiency power systems and the search for practical means for sequestering CO{sub 2} generated by fossil fuel combustion. The selection of particular research projects was guided by a combination of DOE priorities and market needs, as provided by the requirement for joint venture funding approved both by DOE and the private sector sponsor. The research addressed many different energy resource and related environmental problems, with emphasis directed toward the EERC's historic lead mission in low-rank coals (LRCs), which represent approximately half of the U.S. coal resources in the conterminous states, much larger potential resources in Alaska, and a major part of the energy base in the former U.S.S.R., East Central Europe, and the Pacific Rim. The Base and JSRP agreements were tailored to the growing awareness of critical environmental issues, including water supply and quality, air toxics (e.g., mercury), fine respirable particulate matter (PM{sub 2.5}), and the goal of zero net CO{sub 2} emissions.

    The Jointly Sponsored Research Program (JSRP) is a US Department of Energy (DOE) program funded through the Office of Fossil Energy and administered at the Morgantown Energy Technology Center. Under this program, which has been in place since Fiscal Year 1990, DOE makes approximately $2.5 million available each year to the Energy and Environmental Research Center (EERC) to fund projects that are of current interest to industry but which still involve significant risk, thus requiring some government contribution to offset the risk if the research is to move forward. The program guidelines require that at least 50% of the project funds originate from nonfederal sources. Projects funded under the JSRP often originate under a complementary base program, which funds higher-risk projects. The projects funded in Fiscal Year 1996 addressed a wide range of Fossil Energy interests, including hot-gas filters for advanced power systems; development of cleaner, more efficient processing technologies; development of environmental control technologies; development of environmental remediation and reuse technologies; development of improved analytical techniques; and development of a beneficiation technique to broaden the use of high-sulfur coal. Descriptions and status for each of the projects funded during the past fiscal year are included in Section A of this document, Statement of Technical Progress.

    The Joint Science Education Project (JSEP), sponsored by the National Science Foundation, is a two-part program that brings together students and teachers from the United States, Greenland, and Denmark, for a unique cross-cultural, first-hand experience of the realities of polar science field research in Greenland. During JSEP, students experienced research being conducted on and near the Greenland ice sheet by attending researcher presentations, visiting NSF-funded field sites (including Summit and NEEM field stations, both located on the Greenland ice sheet), and designing and conducting research projects in international teams. The results of two of these projects will be highlighted. The atmospheric project investigated the differences in CO2, UVA, UVB, temperature, and albedo in different Arctic microenvironments, while also examining the interaction between the atmosphere and water present in the given environments. It was found that the carbon dioxide levels varied: glacial environments having the lowest levels, with an average concentration of 272.500 ppm, and non-vegetated, terrestrial environments having the highest, with an average concentration of 395.143 ppm. Following up on these results, it is planned to further investigate the interaction of the water and atmosphere, including water's role in the uptake of carbon dioxide. The ecology project investigated the occurrence of unusual large blooms of Nostoc cyanobacteria in Kangerlussuaq area lakes. The water chemistry of the lakes which contained the cyanobacteria and the lakes that did not were compared. The only noticeable difference was of the lakes' acidity, lakes containing the blooms had an average pH value of 8.58, whereas lakes without the blooms had an average pH value of 6.60. Further investigation of these results is needed to determine whether or not this was a cause or effect of the cyanobacteria blooms. As a next step, it is planned to attempt to grow the blooms to monitor their effects on

    The H-mode confinement regime is characterized by a region of good thermal and particle confinement at the edge of the confined plasma, and has generally been envisioned as the operating regime for ITER and other next step devices. This good confinement is often interrupted, however, by edge-localized instabilities, known as ELMs. On the one hand, these ELMs provide particle and impurity flushing from the plasma core, a beneficial effect facilitating density control and stationary operation. On the other hand, the ELMs result in a substantial fraction of the edge stored energy flowing in bursts to the divertor and first wall; this impulsive thermal loading would result in unacceptable erosion of these material surfaces if it is not arrested. Hence, developing and understanding operating regimes that have the energy confinement of standard Hmode and the stationarity that is provided by ELMs, while at the same time eliminating the impulsive thermal loading of large ELMs, is the focus of the 2013 FES Joint Research Target (JRT): Annual Target: Conduct experiments and analysis on major fusion facilities, to evaluate stationary enhanced confinement regimes without large Edge Localized Modes (ELMs), and to improve understanding of the underlying physical mechanisms that allow acceptable edge particle transport while maintaining a strong thermal transport barrier. Mechanisms to be investigated can include intrinsic continuous edge plasma modes and externally applied 3D fields. Candidate regimes and techniques have been pioneered by each of the three major US facilities (C-Mod, D3D and NSTX). Coordinated experiments, measurements, and analysis will be carried out to assess and understand the operational space for the regimes. Exploiting the complementary parameters and tools of the devices, joint teams will aim to more closely approach key dimensionless parameters of ITER, and to identify correlations between edge fluctuations and transport.

    The H-mode confinement regime is characterized by a region of good thermal and particle confinement at the edge of the confined plasma, and has generally been envisioned as the operating regime for ITER and other next step devices. This good confinement is often interrupted, however, by edge-localized instabilities, known as ELMs. On the one hand, these ELMs provide particle and impurity flushing from the plasma core, a beneficial effect facilitating density control and stationary operation. On the other hand, the ELMs result in a substantial fraction of the edge stored energy flowing in bursts to the divertor and first wall; this impulsive thermal loading would result in unacceptable erosion of these material surfaces if it is not arrested. Hence, developing and understanding operating regimes that have the energy confinement of standard H-mode and the stationarity that is provided by ELMs, while at the same time eliminating the impulsive thermal loading of large ELMs, is the focus of the 2013 FES Joint Research Target (JRT): Annual Target: Conduct experiments and analysis on major fusion facilities, to evaluate stationary enhanced confinement regimes without large Edge Localized Modes (ELMs), and to improve understanding of the underlying physical mechanisms that allow acceptable edge particle transport while maintaining a strong thermal transport barrier. Mechanisms to be investigated can include intrinsic continuous edge plasma modes and externally applied 3D fields. Candidate regimes and techniques have been pioneered by each of the three major US facilities (C-Mod, D3D and NSTX). Coordinated experiments, measurements, and analysis will be carried out to assess and understand the operational space for the regimes. Exploiting the complementary parameters and tools of the devices, joint teams will aim to more closely approach key dimensionless parameters of ITER, and to identify correlations between edge fluctuations and transport. The role of rotation will be

    This paper describes a joint Control Structure Interaction (CSI) experiment in which Jet Propulsion Laboratory (JPL) damping devices were incorporated into the Langley Research Center (LaRC) Phase 0 Testbed. The goals of the effort were twofold: (1) test the effectiveness of the JPL structural damping methods in a new structure and (2) assess the feasibility of combining JPL local control methods with the LaRC multiple input multiple output global control methods. Six dampers (2 piezoelectric active members, 4 viscous dampers), placed in three different regions of the structure, produced up to 26 dB attenuation in target modes. The combined control strategy in which the JPL damping methods contributed local control action and the LaRC control scheme provided global control action, produced and overall control scheme with increased stability margins and improved performance. This paper presents an overview of the technologies contributed from the two centers, the strategies used to combine them, and results demonstrating the success of the damping and cooperative control efforts.

    Mixed methods research is becoming an important methodology to investigate complex health-related topics, yet the meaningful integration of qualitative and quantitative data remains elusive and needs further development. A promising innovation to facilitate integration is the use of visual joint displays that bring data together visually to draw out new insights. The purpose of this study was to identify exemplar joint displays by analyzing the various types of joint displays being used in published articles. We searched for empirical articles that included joint displays in 3 journals that publish state-of-the-art mixed methods research. We analyzed each of 19 identified joint displays to extract the type of display, mixed methods design, purpose, rationale, qualitative and quantitative data sources, integration approaches, and analytic strategies. Our analysis focused on what each display communicated and its representation of mixed methods analysis. The most prevalent types of joint displays were statistics-by-themes and side-by-side comparisons. Innovative joint displays connected findings to theoretical frameworks or recommendations. Researchers used joint displays for convergent, explanatory sequential, exploratory sequential, and intervention designs. We identified exemplars for each of these designs by analyzing the inferences gained through using the joint display. Exemplars represented mixed methods integration, presented integrated results, and yielded new insights. Joint displays appear to provide a structure to discuss the integrated analysis and assist both researchers and readers in understanding how mixed methods provides new insights. We encourage researchers to use joint displays to integrate and represent mixed methods analysis and discuss their value. © 2015 Annals of Family Medicine, Inc.

    The Quiet Short-Haul Research Aircraft (QSRA) is a flight facility which Ames Research Center is using to conduct a broad program of terminal area and low-speed, propulsive-life flight research. A joint Navy/NASA flight research program used the QSRA to investigate the application of advanced propulsive-lift technology to the naval aircraft-carrier environment. Flight performance of the QSRA is presented together with the results or the joint Navy/NASA flight program. During the joint program, the QSRA operated aboard the USS Kitty Hawk for 4 days, during which numerous unarrested landings and free deck takeoffs were accomplished. These operations demonstrated that a large aircraft incorporating upper-surface-blowing, propulsive-life technology can be operated in the aircraft-carrier environment without any unusual problems.

    Highlights: • Several rounds insulation trials for ITER Feeder joint were carried out in ASIPP. • Wet-winding, VPI were practiced and attempt for the best impregnation strategy. • Improvement of wet-winding technology with vacuum assistance was realized. • To supplement the electrical test, DR technology was explored for insulation quality inspection. -- Abstract: The ITER Feeder busbar joint is an important component which connects different sections of busbar which run from the high temperature superconducting current leads to the magnet terminals. High voltage insulated bus bar sections will be assembled onto the feeder support structure (called the containment duct), and the joints between sections will be made in situ. The high voltage insulation over the joint is the final step to complete the insulation of the whole bus bar system, and its quality is key to achieving the required electrical performance of the system. The final joint has a complex external configuration with an irregular structure in places, which makes it difficult for the application of the insulation. The limited access in the Feeder and the complex joint external structure make the implementation of the joint insulation hard to solve. The Feeder group at ASIPP has carried out significant R and D for the joint insulation, involving research on the selection of materials, the design of the insulation structure, the curing technology and the quality inspection method. After many rounds of manufacturing and testing, the insulation strategy for the Feeder joint will focus on the so-called “wet-winding” technology. Despite the fact that this process has some intrinsic disadvantages, it is more appropriate for the joint structure compared to other methods. The sub-suppliers to ASIPP have chosen this impregnation method for the feeder qualification activities based on guidance from ASIPP. This paper describes the research procedure of the ITER Feeder busbar joint insulation

  14. Research into the Reliability of the Overlap Joint of Bituminous Heat Welded Roofing Materials

    Full Text Available Abstract The conducted analysis has revealed that the most common reason of leaks in bituminous roofs is caused by a lack of adhesion between two nearby sheets of roof cover. Regarding the above mentioned problems, reliability, testing methods and data analysis methods of the overlap joint is observed more closely. The research conducted by different scientists worldwide has showed difficulties in evaluating the obtained data due to a lack of information on how these samples were produced. Therefore, it is proposed to evaluate the influence of welding time analyzing the mechanical properties of the joints of bituminous heat welded roofing materials. The influence of welding time, when the samples are produced, and mechanical properties of overlap joints are practically proved according to LST standards. The test results have showed that welding time does not have a significant influence on the shear resistance of overlap joints but is important regarding its limited deformation.

    In general, any assessment concerning the safety of nuclear facilities is based on acquired scientific knowledge. Nevertheless, some areas related to safety remain still inadequately explored, knowledge in these areas needs to be further developed either through the results obtained from studies or from experimental research. With the aim of achieving an optimal safety level, one of IPSN's main tasks is to highlight these gags in current knowledge and point out to nuclear facility operators the need to fill them. These general considerations are pertinent to the particular field of fire. At IPSN, safety assessment activities and research are carried out side-by-side, thus facilitating the implementation of corresponding research programs. This ability to orient research with respect to safety assessment requirements, the contribution of research scientists to safety assessment or the formulation of safety problems, are today counted among the strong points of IPSN operation. This paper presents also the present main fire risk safety concerns for Nuclear Power Plants and the associated research carried out by IPSN (past, underway and future) to improve the scientific knowledge in the related areas.

    Geoscience is a multi-disciplinary field and in many cases its research benefits from considering different kinds of observational results. Geoscience observations are in some cases of direct interest also to the public. For these reasons effective knowledge transfer and access also across disciplines are especially important for research infrastructures (RIs) in the environmental domain. More generally, the ultimate success of a RI is measured by its scientific outcome and this is best achieved based on efficient access for a broad scientific community. In this presentation the authors report activities to develop governance tools so that the access to environmental RIs and to the data that they provide is common, fair and based on scientific rationale, regarding at the same time economically and technically reasonable use of limited resources. Implementing such governance tools will indeed foster and widen the access to RIs across environmental science domains while addressing societal challenges. The strategies also need to be flexible and sustainable over the expected lifetimes of the RIs. The reported activities involve researchers from different projects and environmental subdomains that come together in the project ENVRI_plus. ENVRI_plus is a Cluster project of RIs that brings together the current ESFRI roadmap RIs in the environmental domain and other relevant existing and developing RIs and projects. ENVRI_plus also offers opportunities for free-of-charge transnational access to four multi-disciplinary research platforms. These calls for access target research groups and companies wishing to conduct research or to test instruments for cross-disciplinary topics within the environmental domains atmosphere, biosphere, marine, and solid earth. They are initiated specifically to gain experience with access across different disciplines (further information is given at www.envriplus.eu). ENVRI_plus receives funding from the European Union's Horizon 2020 research

    We coordinated anatomy and physiology lectures and practicals to facilitate an integrated understanding of morphology and function in a basic medical science program for dental students and to reduce the time spent on basic science education. This method is a means to provide the essential information and skills in less time. The overall impression was that the practice of joint central nervous system lectures and practicals was an efficient method for students, which suggests that joint lectures might also be useful for clinical subjects. About two-thirds of students felt that the joint anatomy and physiology lecture on the central nervous system was useful and necessary in understanding the relationship between morphology and function, at least for this subject. One-third of students were neutral on the effectiveness of this method. However, the survey results suggest that improvements are needed in the method and timing of joint lectures and practicals. The present teaching approach can be further improved by conducting combined lectures in which the form and function of anatomic structures are presented by the relevant departments during the same lecture. Finally, joint lecturers and practicals offer an opportunity to increase student understanding of the importance of new research findings by the present authors and other researchers.

  9. Biomimetic Spider Leg Joints: A Review from Biomechanical Research to Compliant Robotic Actuators

    Directory of Open Access Journals (Sweden)

    Stefan Landkammer

    2016-07-01

    Full Text Available Due to their inherent compliance, soft actuated joints are becoming increasingly important for robotic applications, especially when human-robot-interactions are expected. Several of these flexible actuators are inspired by biological models. One perfect showpiece for biomimetic robots is the spider leg, because it combines lightweight design and graceful movements with powerful and dynamic actuation. Building on this motivation, the review article focuses on compliant robotic joints inspired by the function principle of the spider leg. The mechanism is introduced by an overview of existing biological and biomechanical research. Thereupon a classification of robots that are bio-inspired by spider joints is presented. Based on this, the biomimetic robot applications referring to the spider principle are identified and discussed.

    2008-06-01

    Musculoskeletal research has brought about revolutionary changes in our ability to perform high precision surgery in joint replacement procedures. Recent advances in computer assisted surgery as well better materials have lead to reduced wear and greatly enhanced the quality of life of patients. The new surgical techniques to reduce the size of the incision and damage to underlying structures have been the primary advance toward this goal. These new techniques are known as MIS or Minimally Invasive Surgery. Total hip and knee Arthoplasties are at all time high reaching 1.2 million surgeries per year in the USA. Primary joint failures are usually due to osteoarthristis, rheumatoid arthritis, osteocronis and other inflammatory arthritis conditions. The methods for THR and TKA are critical to initial stability and longevity of the prostheses. This research aims at understanding the fundamental mechanics of the joint Arthoplasty and providing an insight into current challenges in patient specific fitting, fixing, and stability. Both experimental and analytical work will be presented. We will examine Cementless total hip arthroplasty success in the last 10 years and how computer assisted navigation is playing in the follow up studies. Cementless total hip arthroplasty attains permanent fixation by the ingrowth of bone into a porous coated surface. Loosening of an ingrown total hip arthroplasty occurs as a result of osteolysis of the periprosthetic bone and degradation of the bone prosthetic interface. The osteolytic process occurs as a result of polyethylene wear particles produced by the metal polyethylene articulation of the prosthesis. The total hip arthroplasty is a congruent joint and the submicron wear particles produced are phagocytized by macrophages initiating an inflammatory cascade. This cascade produces cytokines ultimately implicated in osteolysis. Resulting bone loss both on the acetabular and femoral sides eventually leads to component instability. As

  5. Research on Joint Parameter Inversion for an Integrated Underground Displacement 3D Measuring Sensor

    2015-04-01

    Full Text Available Underground displacement monitoring is a key means to monitor and evaluate geological disasters and geotechnical projects. There exist few practical instruments able to monitor subsurface horizontal and vertical displacements simultaneously due to monitoring invisibility and complexity. A novel underground displacement 3D measuring sensor had been proposed in our previous studies, and great efforts have been taken in the basic theoretical research of underground displacement sensing and measuring characteristics by virtue of modeling, simulation and experiments. This paper presents an innovative underground displacement joint inversion method by mixing a specific forward modeling approach with an approximate optimization inversion procedure. It can realize a joint inversion of underground horizontal displacement and vertical displacement for the proposed 3D sensor. Comparative studies have been conducted between the measured and inversed parameters of underground horizontal and vertical displacements under a variety of experimental and inverse conditions. The results showed that when experimentally measured horizontal displacements and vertical displacements are both varied within 0 ~ 30 mm, horizontal displacement and vertical displacement inversion discrepancies are generally less than 3 mm and 1 mm, respectively, under three kinds of simulated underground displacement monitoring circumstances. This implies that our proposed underground displacement joint inversion method is robust and efficient to predict the measuring values of underground horizontal and vertical displacements for the proposed sensor.

    2016-10-15

    An elastic dynamic model of high-speed multi-link precision press considering structural stiffness of rotation joints was established by the finite element method. In the finite element model, rotation joint was established by four bar elements with equivalent stiffness, and connected link was established by beam element. Then, the elastic dynamics equation of the system was established, and modal superposition method was used to solve the dynamic response. Compared with the traditional elastic dynamic model with perfect constraint of the rotation joints, the elastic dynamic response value of the improved model is larger. To validate the presented new method of elastic dynamics analysis with stiffness of rotation joints, a related test of slider Bottom dead center (BDC) position in different speed was designed. The test shows that the model with stiffness of rotation joints is more reasonable. So it provides a reasonable theory and method for dynamic characteristics research of such a multi-link machine.

    Former research work about the modeling of hip joint focus on the upper segment of femoral, and assumes the acetabulum cup is sphere concave, and the acetabulum prostheses is semisphere. A method of acquiring the point data on the surface of the hipbone using the reverse engineering technology is presented. After analyzing the acetabulum surface fitting error, a rotation ellipsoid CAD model is applied to fit the acetabulum surface, and then optimization technique is used to find the geometric parameters of the model. The fitting error between the sphere and rotation ellipsoid is compared and gets the result that the fitting error of rotation ellipsoid is smaller than sphere, and the rotation ellipsoid can describe the shape of the acetabulum better.

  18. Research regarding wires elastic deformations influence on joints positioning of a wire-driven robotic arm

    Science.gov (United States)

    Ciofu, C.; Stan, G.

    2016-08-01

    In this paper, we present the influence of driving wires deformation on positioning precision of joints from an elephant's trunk robotic arm. Robotic arms driven by wires have the joint accuracy largely depending on wires rigidity. The joint moment of resistance causes elastic deformation of wires and it is determined by: manipulated object load, weight loads previous to the analyzed joint and inherent resistance moment of joint. Static load analysis emphasizes the particular wires elastic deformation of each driven joint from an elephant's trunk robotic arm with five degrees of freedom. We consider the case of a constant manipulated load. Errors from each driving system of joints are not part of the closed loop system. Thus, precision positioning depends on wires elastic deformation which is about microns and causes angle deviation of joints about tens of minutes of sexagesimal degrees. The closer the joints to base arm the smaller positioning precision of joint. The obtained results are necessary for further compensation made by electronic corrections in the programming algorithm of the elephant's trunk robotic arm to improve accuracy.

    2008-01-01

    Aerosol and monsoon related droughts and floods are two of the most serious environmental hazards confronting more than 60% of the population of the world living in the Asian monsoon countries. In recent years, thanks to improved satellite and in-situ observations, and better models, great strides have been made in aerosol, and monsoon research respectively. There is now a growing body of evidence suggesting that interaction of aerosol forcing with water cycle dynamics in monsoon regions may substantially alter the redistribution of energy at the earth surface and in the atmosphere, and therefore significantly impact monsoon rainfall variability and long term trends. In this talk, I will describe issues related to societal needs, scientific background, and challenges in studies of aerosol-water cycle interaction in Asian monsoon regions. As a first step towards addressing these issues, the authors call for an integrated observation and modeling research approach aimed at the interactions between aerosol chemistry and radiative effects and monsoon dynamics of the coupled ocean-atmosphere-land system. A Joint Aerosol-Monsoon Experiment (JAMEX) is proposed for 2007-2011, with an enhanced observation period during 2008-09, encompassing diverse arrays of observations from surface, aircraft, unmanned aerial vehicles, and satellites of physical and chemical properties of aerosols, long range aerosol transport as well as meteorological and oceanographic parameters in the Indo-Pacific Asian monsoon region. JAMEX will leverage on coordination among many ongoing and planned national programs on aerosols and monsoon research in China, India, Japan, Nepal, Italy, US, as well as international research programs of the World Climate Research Program (WCRP) and the World Meteorological Organization (WMO).

    The Next European Dipole (NED) Joint Research Activity was launched on 1st January 2004 to promote the development of high performance Nb3Sn conductors in collaboration with European industry (aiming at a non-copper critical current density of 1500 A/mm2 at 4.2 K and 15 T) and to assess the suitability of Nb3Sn technology to the next generation of accelerator magnets (aiming at an aperture of 88 mm and a conductor peak field of ~ 15 T). It is part of the Coordinated Accelerator Research in Europe (CARE) project, involves eight collaborators and is half-funded by the European Union. After briefly recalling the Activity organization, we report the main progress achieved over the last year, which includes: the manufacturing of a double-bath He II cryostat for heat transfer measurements through Nb3Sn conductor insulation, detailed quench computations for various NED-like magnet configurations, the award of two industrial subcontracts for Nb3Sn conductor development, the first results of a cross-calibration progra...

  3. Geo-engineering, Governance, and Social-Ecological Systems: Critical Issues and Joint Research Needs

    Directory of Open Access Journals (Sweden)

    2012-03-01

    Full Text Available The debate about the possibilities to engineer the Earth's climate has changed drastically in the last years. Suggestions of large-scale technological interventions to combat climate change that a decade ago would have been discarded as science fiction are slowly moving into the center of international climate change discussions, research, and politics. In this article, I elaborate three joint key challenges to geo-engineering research from a resilience perspective, with a special emphasis on governance issues. First, I discuss the need to understand geo-engineering proposals from a "planetary boundaries" perspective. Second, I elaborate why the notion of Earth stewardship and geo-engineering are not necessarily in conflict, but instead could be viewed as complementary approaches. Last, I discuss the critical need to explore an institutional setting that is strong enough to weed out geo-engineering proposals that carry considerable ecological risk, but still allow for novelty, fail-safe experimentation, and continuous learning. These issues are critical for our understanding of how to effectively govern global environmental risks, complex systems, and emerging technologies in the Anthropocene.

    The intent of Stanford University's SciVis group is to develop technologies that enabled comparative analysis and visualization techniques for simulated and experimental flow fields. These techniques would then be made available under the Joint Research Interchange for potential injection into the DARWIN Workspace Environment (DWE). In the past, we have focused on techniques that exploited feature based comparisons such as shock and vortex extractions. Our current research effort focuses on finding a quantitative comparison of general vector fields based on topological features. Since the method relies on topological information, grid matching and vector alignment is not needed in the comparison. This is often a problem with many data comparison techniques. In addition, since only topology based information is stored and compared for each field, there is a significant compression of information that enables large databases to be quickly searched. This report will briefly (1) describe current technologies in the area of comparison techniques, (2) will describe the theory of our new method and finally (3) summarize a few of the results.

  9. Joint Assessment of ETRR-2 Research Reactor Operations Program, Capabilities, and Facilities

    2006-05-08

    A joint assessment meeting was conducted at the Egyptian Atomic Energy Agency (EAEA) followed by a tour of Egyptian Second Research Reactor (ETRR-2) on March 22 and 23, 2006. The purpose of the visit was to evaluate the capabilities of the new research reactor and its operations under Action Sheet 4 between the U.S. DOE and the EAEA, ''Research Reactor Operation'', and Action Sheet 6, ''Technical assistance in The Production of Radioisotopes''. Preliminary Recommendations of the joint assessment are as follows: (1) ETRR-2 utilization should be increased by encouraging frequent and sustained operations. This can be accomplished in part by (a) Improving the supply-chain management for fresh reactor fuel and alleviating the perception that the existing fuel inventory should be conserved due to unreliable fuel supply; and (b) Promulgating a policy for sample irradiation priority that encourages the use of the reactor and does not leave the decision of when to operate entirely at the discretion of reactor operations staff. (2) Each experimental facility in operation or built for a single purpose should be reevaluated to focus on those that most meet the goals of the EAEA strategic business plan. Temporary or long-term elimination of some experimental programs might be necessary to provide more focused utilization. There may be instances of emerging reactor applications for which no experimental facility is yet designed or envisioned. In some cases, an experimental facility may have a more beneficial use than the purpose for which it was originally designed. For example, (a) An effective Boron Neutron Capture Therapy (BNCT) program requires nearby high quality medical facilities. These facilities are not available and are unlikely to be constructed near the Inshas site. Further, the BNCT facility is not correctly designed for advanced research and therapy programs using epithermal neutrons. (b) The ETRR-2 is frequently operated to

    Full Text Available Joint distribution in the process of circulation of agricultural products can reduce the cost of agricultural products circulation, improves the efficiency of logistics distribution, but for how to solve the problem of cost allocation has always been the major obstacle to the development of this model. The joint distribution model of agricultural products is presented in this study and then considers the problem of cost reduction in joint distribution of two agricultural products retailers. The amount of cost reduction is regarded as the income of distribution, which is distributed effectively by using game theory and resolve the problem of Cost allocation in joint distribution. Through the analysis of an example the joint distribution model can largely reduce the cost of distribution for agricultural products. Finally, through the distribution cost allocation verified the effectiveness and feasibility of this method of cost allocation.

  11. Key Topics for High-Lift Research: A Joint Wind Tunnel/Flight Test Approach

    Science.gov (United States)

    Fisher, David; Thomas, Flint O.; Nelson, Robert C.

    1996-01-01

    Future high-lift systems must achieve improved aerodynamic performance with simpler designs that involve fewer elements and reduced maintenance costs. To expeditiously achieve this, reliable CFD design tools are required. The development of useful CFD-based design tools for high lift systems requires increased attention to unresolved flow physics issues. The complex flow field over any multi-element airfoil may be broken down into certain generic component flows which are termed high-lift building block flows. In this report a broad spectrum of key flow field physics issues relevant to the design of improved high lift systems are considered. It is demonstrated that in-flight experiments utilizing the NASA Dryden Flight Test Fixture (which is essentially an instrumented ventral fin) carried on an F-15B support aircraft can provide a novel and cost effective method by which both Reynolds and Mach number effects associated with specific high lift building block flows can be investigated. These in-flight high lift building block flow experiments are most effective when performed in conjunction with coordinated ground based wind tunnel experiments in low speed facilities. For illustrative purposes three specific examples of in-flight high lift building block flow experiments capable of yielding a high payoff are described. The report concludes with a description of a joint wind tunnel/flight test approach to high lift aerodynamics research.

  12. Implementing joint tuberculosis projects in Somaliland and Sweden for mutual strengthening of programs and research

    Discussion and conclusions: Herein this study presents a planned TB project aiming at cooperation between healthcare staff from a low- and a high-endemic country. For such a project, several baseline data are required, e.g., the pattern of resistance of MTB and the treatment outcome in Somaliland, as well as among immigrants in Sweden. The social circumstances for any patient with TB, whether in Somaliland or Sweden, during disease and when recovered is a main issue for health from a holistic perspective. Further, the nutritional status is not satisfactory for TB patients in either country, and a dietary intervention may be of importance in both countries. Baseline data according to the above are necessary for assessment of the interventions and are part of ongoing pre-studies. For the Swedish party the exchange of clinical knowledge is beneficial since TB is rare in Sweden and access to TB research and clinical implantation of new methods will be facilitated and possible through the joint project. Ultimately, an expanded project could curb TB at the source and decrease TB in both countries.

    Full Text Available Structure characteristics of rock and orebody in deep borehole are obtained by borehole camera technology. By investigating on the joints and fissures in Shapinggou molybdenum mine, the dominant orientation of joint fissure in surrounding rock and orebody were statistically analyzed. Applying the theory of metallogeny and geostatistics, the relationship between joint fissure and lode’s extension direction is explored. The results indicate that joints in the orebody of ZK61borehole have only one dominant orientation SE126° ∠68°, however, the dominant orientations of joints in surrounding rock were SE118° ∠73°, SW225° ∠70° and SE122° ∠65°, NE79° ∠63°. Then a preliminary conclusion showed that the lode’s extension direction is specific and it is influenced by joints of surrounding rock. Results of other boreholes are generally agree well with the ZK61, suggesting the analysis reliably reflects the lode’s extension properties and the conclusion presents important references for deep ore prospecting.

    to assess the effects of radioactive emissions from the EU Joint Research Centre (JRC) (nuclear) at Ispra, the Local Health Authority (ASL) of Varese carried out an ecological study to measure any excess incidence of cancer in the surrounding population. after estimation of historical exposure levels in the surrounding population, the incidence rates of leukaemia and other exposure-related tumours were calculated from data in the population based Lombardy Cancer Registry (Varese Province). By indirect standardization, the expected cases (based on incidence rate in the Province) were compared with observed cases in the close-by municipality of Ispra, in municipalities within a 5 km radius of the JRC (5kmArea) and in the area covered by the District of Sesto Calende (DistrictArea). in the period 1982-1998, mean populations were 4,687 (Ispra), 32,120 (5kmArea) and 43,707 (DistrictArea); the population of the Province was 793,752. The numbers of cancers registered were 374, 2,920, 4,099 and 72,246 respectively. Significant excesses of leukaemia were not found in Ispra (SIR 0.33, 95% CI 0.07-0.96) or the 5kmArea (SIR 0.83, 95% CI 0.63-1.08). For all cancers combined and for the commonest cancers (breast, colo-rectal) the numbers of incident cases were lower than expected. consistent with the low levels of exposure detected, and despite the fears of the local people, no incidence excesses of cancers was found in Ispra, the town closest to the JRC, or inforin the surrounding areas. It may be worth searching for excess cancer among exposed workers.

    Elaboration of the evaluation guidelines for activities implemented jointly (AIJ) was researched to prevent the earth from warming. AIJ is the means to globally promote countermeasures against global warming cost-effectively by optimally combining every country`s technology, know-how and fund. AIJ was established in the 1st Conference of the Parties (COPI) of the United Nations Framework Convention on Climate Change in March, 1995. The pilot phase of AIJ is first carried out by voluntary workers jointly with developing countries under the agreement of the parties. The current situation of activities is reported in COPI as materials for evaluation of AIJ. To promote AIJ, elaboration of the evaluation guidelines for AIJ Japan program is also necessary for Japan. This research arranged the contents of the evaluation guidelines and the method of classifying projects for AIJ Japan program, and carried out some case studies of promising projects to reduce greenhouse gas emission for future proposal. 3 figs., 31 tabs.

    As an important structural member in self-supporting concrete floor during construction, encased steel truss-concrete composite beam has brilliant prospect in outer-jacketing structures for adding stories or mega frame structures. Compared with encased angle truss, encased round steel tube truss can facilitate layout of itself in column and facilitate layout and anchorage of prestressed reinforcement placed horizontally. N-joint is wildly used in encased steel truss. For cave-in failure easily occurs in hollow steel-tube joint, the idea that the chord is grouted to increase cave-in bearing capacity of hollow tube is proposed. Test results of 8 grouted-roundsteel-tube N-joints from the beginning of loading to failure are reported. Mechanical property and failure mode of this kind of truss joint are analyzed, and the formulas of ultimate bearing capacity of the joint corresponding to different failure modes are established. All these can provide basic data for spreading encased steel truss-concrete composite beam.

    A model for an international undergraduate biomedical engineering research exchange program is outlined. In 2008, the Johns Hopkins University in collaboration with Tsinghua University in Beijing, China established the Tsinghua-Johns Hopkins Joint Center for Biomedical Engineering Research. Undergraduate biomedical engineering students from both universities are offered the opportunity to participate in research at the overseas institution. Programs such as these will not only provide research experiences for undergraduates but valuable cultural exchange and enrichment as well. Currently, strict course scheduling and rigorous curricula in most biomedical engineering programs may present obstacles for students to partake in study abroad opportunities. Universities are encouraged to harbor abroad opportunities for undergraduate engineering students, for which this particular program can serve as a model.

  3. Research regarding stiffness optimization of wires used for joints actuation from an elephant's trunk robotic arm

    Ciofu, C.; Stan, G.

    2016-11-01

    Elephant's trunk robotic arms driven by wires and pulley mechanisms have issues with wires stiffness because of the entailed elastic deformations that is causing errors of positioning. Static and dynamic loads from each joint of the robotic arm affect the stiffness of driving wires and precision positioning. The influence of wires elastic deformation on precision positioning decreases with the increasing of wires stiffness by using different pre-tensioning devices. In this paper, we analyze the variation of driving wires stiffness particularly to each wire driven joint. We obtain optimum wires stiffness variation by using an analytical method that highlights the efficiency of pre-tensioning mechanism. The analysis of driving wires stiffness is necessary for taking appropriate optimization measures of robotic arm dynamic behavior and, thus, for decreasing positioning errors of the elephant's trunk robotic arm with inner actuation through wires/cables.

    The aim of this paper is to determine the effect of arrangement of fibreglass fabric plies in a polymer composite on adhesive joint strength. Based on the experimental results, the real effect of plies arrangement and their most favourable configuration with respect to strength is determined. The experiments were performed on 3 types of composites which had different fibre orientations. The composites had three plies of fabric. The plies arrangement in Composite I was unchanged, in Composite II the central ply had the 45° orientation, while in Composite III the outside ply (tangential to the adhesive layer) was oriented at 45°. Composite plates were first cut into smaller specimens and then adhesive-bonded in different combinations with Epidian 61/Z1/100:10 epoxy adhesive. After stabilizing, the single-lap adhesive joints were subjected to shear strength tests. It was noted that plies arrangement in composite materials affects the strength of adhesive joints made of these composites between the values of the strength of the confidence level of 0.95. The statistical analysis of the results also showed that there are no statistical significant differences in average values of surface free energy (0.95 confidence level).

    2014-05-01

    This article reports the results of a review of the research evidence related to joint working in the field of adult health and social care services in the UK. It explores whether recent reforms to joint working have met the objectives set by policy-makers. The review followed an established methodology: electronic databases were searched using predetermined terms, abstracts were screened against inclusion criteria, studies that met the criteria were read in full and assessed for inclusion and data were extracted systematically. The findings of the review suggest that there is some indication that recent developments, in particular the drive to greater integration of services, may have positive benefits for organisations as well as for users and carers of services. However, the evidence consistently reports a lack of understanding about the aims and objectives of integration, suggesting that more work needs to be done if the full potential of the renewed policy agenda on integration is to be realised. Additionally, while the review acknowledges that greater emphasis has been placed on evaluating the outcome of joint working, studies largely report small-scale evaluations of local initiatives and few are comparative in design and therefore differences between 'usual care' and integrated care are not assessed. This makes it difficult to draw firm conclusions about the effectiveness of UK-based integrated health and social care services.

    The heavy ion project consisted of 2 parts; clinical studies using HIMAC and joint basic researches using it. The clinical studies have been satisfactorily progressed and the number of patients treated by HIMAC reached 230 in total by the end of the fiscal year 1996. In Japan, HIMAC is the only apparatus for heavy ion acceleration. Thus, a lot of concerns from not only the medical and biological fields, but also other fundamental fields are paid to HIMAC. Further, the beam of HIMAC has been attracting international concerns, especially in the fields such as simulation of cosmic environment by heavy ion beam, dose determination using the beam, international comparison of its biological effects, etc. The operating times of HIMAC in 1996 was ca. 4800 hours in total and of those ca. 2700 hours were used for joint researches. This annual report include 12 reports of clinical research group, 4 of diagnosis one 64 of biology one and 42 of physical and engineering one. (M.N.)

    In 1996 the 'Landesforschungsbeirat Baden-Wuerttemberg' (Research Council of the Federal State) recommended a critical inventory of ecotoxicological research activities in Baden-Wuerttemberg in order to get a clearly defined orientation as well as a promotion of research. Assigned by the Ministry of Science, Research and Arts Baden-Wuerttemberg, the Center of Technology Assessment (Center of TA) designed and performed a project 'The Research Profile of Ecotoxicology in Baden-Wuerttemberg' with a focus on universities. Research activities in the federal state were registered, documented, and classified. In two round table discussions with experts from university and non-university research institutions, chemical industry, and ministries, the concept of the Center of TA for joint research projects in the field of ecotoxicology in Baden-Wuerttemberg was put in concrete terms. Joint research projects beyond university boundaries are presumably the most promising tool for ecotoxicology to grain profile as a discipline. Ideally, the strong points of several subjects should be combined; thus, creating synergy effects and enabling a comprehensive view of the research topic.

    In 1996 the 'Landesforschungsbeirat Baden-Wuerttemberg' (Research Council of the Federal State) recommended a critical inventory of ecotoxicological research activities in Baden-Wuerttemberg in order to get a clearly defined orientation as well as a promotion of research. Assigned by the Ministry of Science, Research and Arts Baden-Wuerttemberg, the Center of Technology Assessment (Center of TA) designed and performed a project 'The Research Profile of Ecotoxicology in Baden-Wuerttemberg' with a focus on universities. Research activities in the federal state were registered, documented, and classified. In two round table discussions with experts from university and non-university research institutions, chemical industry, and ministries, the concept of the Center of TA for joint research projects in the field of ecotoxicology in Baden-Wuerttemberg was put in concrete terms. Joint research projects beyond university boundaries are presumably the most promising tool for ecotoxicology to grain profile as a discipline. Ideally, the strong points of several subjects should be combined; thus, creating synergy effects and enabling a comprehensive view of the research topic. We assume some organizational preconditions to be necessary for joint projects in order to be successful. Apart from a tight coordination, integrating measures are particularly important. Thus, a project should be obligatorily performed by at least one representative of environmental chemistry and one representative of research on biological effects.

    Clay, Alexis; Delord, Elric; Couture, Nadine; Domenger, Gaël

    We describe the joint research that we conduct in gesture-based emotion recognition and virtual augmentation of a stage, bridging together the fields of computer science and dance. After establishing a common ground for dialogue, we could conduct a research process that equally benefits both fields. As computer scientists, dance is a perfect application case. Dancer's artistic creativity orient our research choices. As dancers, computer science provides new tools for creativity, and more importantly a new point of view that forces us to reconsider dance from its fundamentals. In this paper we hence describe our scientific work and its implications on dance. We provide an overview of our system to augment a ballet stage, taking a dancer's emotion into account. To illustrate our work in both fields, we describe three events that mixed dance, emotion recognition and augmented reality.

    This report describes the result of study on disposal method of graphite blocks in future block-type reactor. Present study was carried out within a framework of joint research, ''Research of Modular High Temperature Gas-cooled Reactors (No. 3)'', between Japan Atomic Energy Research Institute (JAERI) and the Japan Atomic Power Company (JAPCO), in 2000. In this study, activities in fuel and reflector graphite blocks were evaluated and were compared with the disposal limits defined as low-level of radioactive waste. As a result, it was found that the activity for only C-14 was higher than disposal limits for the low-level of radioactive waste and that the amount of air in the graphite is important to evaluate precisely of C-14 activity. In addition, spent fuels can be stored in air-cooled condition at least after two years cooling in the storage pool. (author)

    Tremor usually occurs in a patient's upper limb with a roughly sinusoidal profile. Understanding the inner mechanism of the involuntary movement is fundamental to improving tremor suppression treatments. Therefore, the musculoskeletal model of the elbow joint was developed in this study. Initially, healthy subjects were selected to simulate tremor and the tremulous data was collected with the purpose of sparing patients from fatigue. With the recorded joint angle and surface EMG (sEMG), the model was calibrated to subjects by optimization approach. The activation derived from the electric pulse was employed to drive the tuned model and the model's output was compared with the angle predicted by the EMG-driven musculoskeletal model. The results demonstrated that the performance of the calibrated model was improved by a smaller normalized root mean square error and a higher coefficient of determination compared with the no-tuned model. There was no significant difference between the angles estimated by the tuned model activated by the electric pulse and muscle excitation. It indicates that neural activation could be replaced by the electric pulse to excite the limbs for desired angle. Therefore, the study presents a good way to evaluate the feasibility of Functional Electric Stimulation to suppress tremor.

    As modern medicine getting deeply to understand ever-detailed anatomy,structure and animal mechanics of the patellofemoral joint, excessive lateral pressure syndrome, a very common patellofemoral disorder, has been reacquainted by the clinicians. On account to the complexity and variety of the etiology and the mechanism of the pain, still, there are many difficulties and arguments on the exact description of the clinical symptoms and the establishment of a universally accepted diagnostic criteria. Accurately grasping different causes, pathomechanisms and developmental stages of the disease would be especially important. As a result, rational choice of the pertinent procedures become the clinical lynchpin. This paper reviews domestic and international pertinent literatures in the past 10 years, and provide an overview of the latest study of anatomy, biomechanic, pathomechanism and clinical experience, anticipating to offer help on standardizing the diagnosis and treatment of ELPS.

    Full Text Available Longitudinal data on aging, health and longevity provide a wealth of information to investigate different aspects of the processes of aging and development of diseases leading to death. Statistical methods aimed at analyses of time-to-event data jointly with longitudinal measurements became known as the joint models (JM. An important point to consider in analyses of such data in the context of studies on aging, health, and longevity is how to incorporate knowledge and theories about mechanisms and regularities of aging-related changes that accumulate in the research field into respective analytic approaches. In the absence of specific observations of longitudinal dynamics of relevant biomarkers manifesting such mechanisms and regularities, traditional approaches have a rather limited utility to estimate respective parameters that can be meaningfully interpreted from the biological point of view. A conceptual analytic framework for these purposes, the stochastic process model of aging (SPM, has been recently developed in the biodemographic literature. It incorporates available knowledge about mechanisms of aging-related changes which may be hidden in the individual longitudinal trajectories of physiological variables and this allows for analyzing their indirect impact on risks of diseases and death. Despite, essentially, serving similar purposes, JM and SPM developed in parallel in different disciplines with very limited cross-referencing. Although there were several publications separately reviewing these two approaches, there were no publications presenting both these approaches in some detail. Here we overview both approaches jointly and provide some new modifications of SPM. We discuss the use of stochastic processes to capture biological variation and heterogeneity in longitudinal patterns and important and promising (but still largely underused applications of JM and SPM to predictions of individual and population mortality and health

    The pilot phase of the activities implemented jointly (AIJ) was approved in 1995 in the 1st Conference of the Parties (COPI) of the United Nations Framework Convention on Climate Change to reduce greenhouse gas emission. In order to promote the AIJ Japan program smoothly, some practical examples in every preceding country and the situations and demands of Asian countries were researched. It was confirmed that since larger cost-effectiveness is achieved just in countries lower in emission control cost, AIJ can enhance the cost-effectiveness and promote environmental technology transfer. Japanese government had studied establishment of the framework for AIJ, and decided the basic framework of the AIJ Japan program in 1995. The government also approved the evaluation guidelines of this program which include confirmed and considered matters necessary for government offices related to this program to evaluate and approve each project.

    The Joint FAO/WHO/IOC ad hoc Expert Consultation on Biotoxins in Molluscan Bivalves performed risk assessments for a number of biotoxins present in bivalve molluscs. For performing risk assessments, the Expert Consultation categorized the biotoxins into eight distinct groups based on chemical structure. The Expert Consultation established LOAELs for the azaspiracid (AZA), okadaic acid (OA), saxitoxin (STX), and domoic acid (DA) toxin groups. The derived provisional acute RfDs for the AZA, OA, STX, and DA toxin groups were 0.04 microg/kg bw, 0.33 microg/kg bw, 0.7 microg/kg bw, and 100 microg/kg bw, respectively. For the yessotoxin (YTX) group, a NOAEL was established, based on animal studies. Applying a safety factor of 100, a provisional acute RfD of 50 microg/kg bw was suggested for the YTX group. The Expert Consultation considered that the database for cyclic imines, brevetoxins, and pectenotoxins was insufficient to establish provisional acute RfDs for these three toxin groups.

    In DMH research the use of “ethics-as-process” can enable adaptation to the ‘unknown unknowns’ but there will be an increasing need for protocols to be established and maintained. Significant in these protocols will be guidance from DMH services as to how research can be encouraged as well as their position of responsibility. DMH services would benefit from a ‘toolkit’ to support their decision-making on which research to participate in, and how best to involve their users in this process.

    Full Text Available To increase the uptake of research findings by policy makers and to encourage European researchers to better reflect policy needs, we facilitated the development of a joint research agenda (JRA on sustainable food consumption (SFC involving scientists, policy makers, and other stakeholders. Pursuing interpretive action research and using a number of data sources, we tried to understand how the “fit” between the characteristics of policy makers’ organizational contexts and the attributes of the JRA development process affects the reception of the JRA and its outcomes. Our framework was based on three distinct formations of discursive and material practices related to the use of knowledge in public policy making: bureaucratic, managerial, and communicative. Two dominant patterns seem to be represented in SFC consumption in the European Union: a transition between the bureaucratic and the managerial formation and a highly developed managerial formation with occasional communicative practices. We found that reflecting national policy priorities would help overcome some of the structural barriers between science and policy, whereas other barriers could be addressed by designing the process to better fit with the logics of the three formations, such as the fragmentation of knowledge (bureaucratic formation or breadth of participation (communicative formation.

    The Joint Space Operations Center (JSpOC) Mission System (JMS) is a service-oriented architecture (SOA) infrastructure with increased process automation and improved tools to enhance Space Situational Awareness (SSA) performed at the US-led JSpOC. The Advanced Research, Collaboration, and Application Development Environment (ARCADE) is a test-bed maintained and operated by the Air Force to (1) serve as a centralized test-bed for all research and development activities related to JMS applications, including algorithm development, data source exposure, service orchestration, and software services, and provide developers reciprocal access to relevant tools and data to accelerate technology development, (2) allow the JMS program to communicate user capability priorities and requirements to developers, (3) provide the JMS program with access to state-of-the-art research, development, and computing capabilities, and (4) support JMS Program Office-led market research efforts by identifying outstanding performers that are available to shepherd into the formal transition process. In this paper we will share with the international remote sensing community some of the recent JMS and ARCADE developments that may contribute to greater SSA at the JSpOC in the future, and share technical areas still in great need.

    2010-01-15

    This review article addresses the best evidence currently available for the effectiveness of injection therapy for musculoskeletal conditions involving the peripheral joints. The research is presented by anatomical region and areas of controversy and the need for additional research are identified. Randomized controlled trials, meta-analyses and systematic reviews are lacking that address the effectiveness of therapeutic injections to the sternoclavicular, acromioclavicular, ankle and foot joints. No research studies of any kind have been reported for therapeutic injections of the sternoclavicular joint. With the exception of the knee, possibly the hip and patients with inflammatory arthropathies, research does not unequivocally support the use of therapeutic joint injections for most of the peripheral joints, including the shoulder. Additionally, controversy exists in some areas as to whether or not corticosteroids provide better outcomes compared to local anesthetic injections alone. When viscosupplementation injections are compared to corticosteroids in patients with osteoarthritis of the knee, the evidence supports the use of viscosupplementation for more prolonged improvement in outcomes, with corticosteroids being good for short-term relief.

    The pilot system on the distributed database for advanced nuclear materials named `Data-Free-Way` was constructed under the collaboration of National Research Institute for Metals, Japan Atomic Energy Research Institute, and Power Reactor and Nuclear Fuel Development Corporation during fiscal years from 1990 through 1994. In order to make the system more substantial, the second stage collaborative research activity in which the main objective was to develop the utilization techniques for `Data-Free-Way` was initiated in 1995 among three above-mentioned organizations and Japan Science and Technology Corporation, which newly joined this program. In the second stage collaborative research activity, some trials of attractive utilization of the system focused on the issues relating to various properties of superalloy were performed by using the PC on the Internet. In future each organization will update the system for improving the interface of the system and enrich the stored data with debugging. (author)

    The BonaRes Project ("Soil as a sustainable resource for the bioeconomy") was launched in 2015 to promote sustainable soil management and to avoid fragmentation of efforts (Wollschläger et al., 2016). For this purpose, an IT infrastructure is being developed to upload, manage, store, and provide research data and its associated metadata. The research data provided by the BonaRes data centre are, in principle, not subject to any restrictions on reuse. For all research data considerable standardized metadata are the key enablers for the effective use of these data. Providing proper metadata is often viewed as an extra burden with further work and resources consumed. In our lecture we underline the benefits of structured and interoperable metadata like: accessibility of data, discovery of data, interpretation of data, linking data and several more and we counter these advantages with the effort of time, personnel and further costs. Building on this, we describe the framework of metadata in BonaRes combining the standards of OGC for description, visualization, exchange and discovery of geodata as well as the schema of DataCite for the publication and citation of this research data. This enables the generation of a DOI, a unique identifier that provides a permanent link to the citable research data. By using OGC standards, data and metadata become interoperable with numerous research data provided via INSPIRE. It enables further services like CSW for harvesting WMS for visualization and WFS for downloading. We explain the mandatory fields that result from our approach and we give a general overview about our metadata architecture implementation.

    1994-09-01

    Numerous studies have been conducted in five principal areas: oil shale, tar sand, underground coal gasification, advanced process technology, and advanced fuels research. In subsequent years, underground coal gasification was broadened to be coal research, under which several research activities were conducted that related to coal processing. The most significant change occurred in 1989 when the agreement was redefined as a Base Program and a Jointly Sponsored Research Program (JSRP). Investigations were conducted under the Base Program to determine the physical and chemical properties of materials suitable for conversion to liquid and gaseous fuels, to test and evaluate processes and innovative concepts for such conversions, to monitor and determine environmental impacts related to development of commercial-sized operations, and to evaluate methods for mitigation of potential environmental impacts. This report is divided into two volumes: Volume 1 consists of 28 summaries that describe the principal research efforts conducted under the Base Program in five topic areas. Volume 2 describes tasks performed within the JSRP. Research conducted under this agreement has resulted in technology transfer of a variety of energy-related research information. A listing of related publications and presentations is given at the end of each research topic summary. More specific and detailed information is provided in the topical reports referenced in the related publications listings.

    Research was made to promote Activities Implemented Jointly Japan Program. Joint Implementation (JI) is the methodology for preventing global climate changes by collaboration of countries. The countries take cooperative actions for reduction, absorption and fixation of greenhouse gases, and effectively distribute the reduction credits among relevant parties. This was decided in the first session of the Conference of Parties (COP) held in March, 1995. In COP3, Japan`s assigned reduction amount in 2008-2012 was determined as 6% of the emission level in 1990. The protocol defines JI between parties as dealings of emission reduction units, and JI between developing countries as clean development mechanism. The rules for a base line and credit distribution are necessary before full-scale implementation. Although JI is regarded as an important cost-effective project, it is important to decide where and how the JI projects should been promoted. The present state and issues of the primary approved project of Japan Program are arranged. In particular, various terms related to developing countries remain to be solved. 21 figs., 32 tabs.

    Improvements in analytical methodology have allowed low-level detection of an ever increasing number of pharmaceuticals, personal care products, hormones, pathogens and other contaminants of emerging concern (CECs). The use of these improved analytical tools has allowed researchers to document the global presence of CECs derived from a wide range of urban (e.g. wastewater treatment plants, onsite septic systems, landfills) and agricultural (e.g. livestock and crop production) sources. In addition, such research has documented that CECs are sufficiently mobile and persistent to be transported to all environmental compartments (e.g. surface water, stream bed sediment, groundwater, soil, tissue).

  1. Introducing Joint Research Project «Quantum Ampere» for the realisation of the new SI ampere

    Directory of Open Access Journals (Sweden)

    Scherer Hansjörg

    2014-01-01

    Full Text Available The metrology community lately has adopted the long-term aim of basing the SI unit system on fundamental constants of nature. The base electrical unit, the ampere, will then be re-defined in terms of a fixed value of the elementary charge e. The most direct realization of the new ampere definition requires controlling the number of electrons which flow in a unit time interval, and of counting the errors occurring in this process of clocking single electrons. State of the art nanofabrication technology allows the fabrication of single-electron transport devices - known as single-electron pumps - which generate electric current by moving electrons one at a time. These devices are capable of delivering currents of about 100 pA with an accuracy at the 1 part per million level. Also, ultrasensitive single-electron detectors have been explored that allow electric charge detection on a resolution level below e. The European Joint Research Project presented here, undertaken by a consortium of several research institutes, aims at further developing the best existing concepts of single-electron pumps and to combine them with single-electron detectors for creating highly accurate quantum current sources, to be used as future current standards. Furthermore, necessary current measurement instrumentation will be developed. The paper comprises the project aims and the main results achieved so far.

    This work is being carried out as a feasibility study to determine if a long-term course of work can be implemented to assess the long-term risks of radiation exposure delivered at low to moderate dose rates to the populations living in the vicinity of the Mayak Industrial Association (MIA). This work was authorized and conducted under the auspices of the US-Russian Joint Coordinating Committee on Radiation Effects Research (JCCRER) and its Executive Committee (EC). The MIA was the first Russian site for the production and separation of plutonium. This plant began operation in 1948, and during its early days there were technological failures that resulted in the release of large amounts of waste into the rather small Techa River. There were also gaseous releases of radioiodines and other radionuclides during the early days of operation. In addition, there was an accidental explosion in a waste storage tank in 1957 that resulted in a significant release. The Techa River Cohort has been studied for several years by scientists from the Urals Research Centre for Radiation Medicine and an increase in both leukemia and solid tumors has been noted.

    As a consequence of the Chernobyl nuclear power plant accident in 1986, all European countries have installed automatic dosimetry network stations as well as air sampling systems for the monitoring of airborne radioactivity. In Europe, at present, almost 5,000 stations measure dose rate values in nearly real time. In addition, a few hundred air samplers are operated. Most of them need extended accumulation times with no real-time capability. National dose rate data are provided to the European Commission (EC) via the EUropean Radiological Data Exchange Platform (EURDEP). In case of a nuclear emergency with transboundary implications, the EC may issue momentous recommendations to EU member states based on the radiological data collected by EURDEP. These recommendations may affect millions of people and could have severe economic and sociological consequences. Therefore, the reliability of the EURDEP data is of key importance. Unfortunately, the dose rate and activity concentration data are not harmonized between the different networks. Therefore, within the framework of the European Metrology Research Programme (EMRP), 16 European institutions formed the consortium MetroERM with the aim to improve the metrological foundation of measurements and to introduce a pan-European harmonization for the collation and evaluation of radiological data in early warning network systems. In addition, a new generation of detector systems based on spectrometers capable of providing both reliable dose rate values as well as nuclide specific information in real time are in development. The MetroERM project and its first results will be presented and discussed in this article.

    For the research on fatigue performance of hinge joints with different structures ,two hinged slab bridges with deep hinge joints and shallow hinge joints were adopted in the experiments .Based on the results of the transverse strains regularity of hinge joints at the middle span of hinged slab ,the researches on the fatigue performance of the hinge joints were carried out .The transverse strains of hinge joints include the concrete transverse strain at the bottom and the top of hinge joints ,and the transverse strain of the connection steels in hinge joints .The experimental results suggest that , within 2 × 106 times of fatigue load ,due to the relatively small fatigue amplitudes ,the concrete and reinforcement strain values of hinge joints decrease as static load applied after the fatigue cycle of certain numbers ,with the increasing of fa-tigue cycle number ,the changes of the strain values tend to be more stable .When the fatigue cycle number is more than 2 × 106 times ,as the fatigue amplitudes increase ,the influence on the damage of shallow hinge joints by fatigue load is great ,but no obvious influence on deep hinge joints .Therefore ,the fatigue load with certain fatigue amplitude is a major factor which causes the destruction of shallow hinge joints ,and the fatigue damage resistance performance of deep hinge joints is much better than shallow hinge joints .%为研究不同构造的铰接板桥铰缝的疲劳性能,采用深铰缝和浅铰缝两种形式的铰接板桥进行试验研究,通过对跨中铰缝顶底部混凝土的横向应变规律及铰缝内部横向连接钢筋的应变规律进行对比分析,对铰缝的疲劳性能进行研究。试验结果表明,在200万次疲劳荷载以前,由于疲劳幅值相对较小,随着疲劳次数的增加,完成一定疲劳循环后施加静载时铰缝混凝土及钢筋的应变值逐渐减小,应变值的变化趋于更加稳定。当疲劳次数超过200万次后,由于疲劳幅

    Palliative medicine is an interdisciplinary specialty focusing on improving quality of life (QOL) for patients with serious illness and their families. Palliative care programs are available or under development at over 80% of large US hospitals (300+ beds). Palliative care clinical trials present unique analytic challenges relative to evaluating the palliative care treatment efficacy which is to improve patients' diminishing QOL as disease progresses towards end of life (EOL). A unique feature of palliative care clinical trials is that patients will experience decreasing QOL during the trial despite potentially beneficial treatment. Often longitudinal QOL and survival data are highly correlated which, in the face of censoring, makes it challenging to properly analyze and interpret terminal QOL trend. To address these issues, we propose a novel semiparametric statistical approach to jointly model the terminal trend of QOL and survival data. There are two sub-models in our approach: a semiparametric mixed effects model for longitudinal QOL and a Cox model for survival. We use regression splines method to estimate the nonparametric curves and AIC to select knots. We assess the model performance through simulation to establish a novel modeling approach that could be used in future palliative care research trials. Application of our approach in a recently completed palliative care clinical trial is also presented. Copyright © 2017 John Wiley & Sons, Ltd.

    This research review aims to focus attention on the effect of specific surgical and host factors on implant fixation, and the importance of accounting for them in experimental and numerical models. These factors affect (a) eventual clinical applicability and (b) reproducibility of findings across research groups. Proper function and longevity for orthopedic joint replacement implants relies on secure fixation to the surrounding bone. Technology and surgical technique has improved over the last 50 years, and robust ingrowth and decades of implant survival is now routinely achieved for healthy patients and first-time (primary) implantation. Second-time (revision) implantation presents with bone loss with interfacial bone gaps in areas vital for secure mechanical fixation. Patients with medical comorbidities such as infection, smoking, congestive heart failure, kidney disease, and diabetes have a diminished healing response, poorer implant fixation, and greater revision risk. It is these more difficult clinical scenarios that require research to evaluate more advanced treatment approaches. Such treatments can include osteogenic or antimicrobial implant coatings, allo- or autogenous cellular or tissue-based approaches, local and systemic drug delivery, surgical approaches. Regarding implant-related approaches, most experimental and numerical models do not generally impose conditions that represent mechanical instability at the implant interface, or recalcitrant healing. Many treatments will work well in forgiving settings, but fail in complex human settings with disease, bone loss, or previous surgery. Ethical considerations mandate that we justify and limit the number of animals tested, which restricts experimental permutations of treatments. Numerical models provide flexibility to evaluate multiple parameters and combinations, but generally need to employ simplifying assumptions. The objectives of this paper are to (a) to highlight the importance of mechanical

    Ever since it was demonstrated that Jatropha seed oil could be converted into a world class biodiesel and could run in unmodified stationary and mobile diesel engines with simultaneous reduction in emissions, it caught the attention of the world. The capability to grow this crop on wastelands added to its attractiveness. However, the single biggest challenge came in the form of the availability of adequate feed stock in the form of the Jatropha fruit. Adequacy of feed stock can only be possible if large plantations are cultivated and produce enough fruit. The people, world over, jumped into Jatropha cultivation without heeding to the need to first ensure quality germplasm and understand the agronomic requirements of the plants. As a result many plantations failed to give the required yield. CSIR-CSMCRI had been researching Jatropha and had an end-to-end approach, i.e., it developed the best technology to prepare biodiesel and also worked towards the practical problems that it envisaged to be important for raising Jatropha productivity. It focused only on cultivation on wastelands as this was the only practical strategy, given the limited arable land India has and the risk of food security for the burgeoning population. While working in this direction, the Institute zeroed-in on a few germplasm, which gave consistently higher seed yield over several years. These germplasm were clonally propagated in large numbers to be raised in experimental plantations at different geographical locations in India. Many agronomic practices were developed as a part of these different projects. It was at this juncture that General Motors and the U.S. Department of Energy joined hands with CSIR-CSMCRI to further the work on Jatropha. A center of expertise for Jatropha was established and work was initiated to further refine the understanding regarding the best practices. Efforts were to be made to generate primary data, hitherto unavailable for wastelands, on which life cycle

    This paper presents the survey and research work of two land-sea profiles in the Bohai Sea, China, carried out in 2010-2011, including the seismic sources on land and in the sea, the ocean bottom seismographs (OBS) and their recovery, the coupling of OBS and the environment noise in sea area, the data quality of OBSs, and the result of data analysis. We focused on the investigation of crustal structures revealed by the two NE\\EW-trending joint land-sea profiles. In combination with the Pn-velocity distribution and gravity-magnetic inversion results in the North China Craton, we propose that the undulation of the Moho interface in the Bohai and surrounding areas is not strong, and the lithospheric thinning is mainly caused by the thinning of its mantle part. The research result indicates that obvious lateral variations of Moho depth and seismic velocity appear nearby all the large-scale faults in Bohai Sea, and there is evidence of underplating and reforming of the lower crust by mantle material in the Bohai area. However, geophysical evidence does not appear to support the“mantle plume”or“delamination”model for the North China Craton destruction. The crustal structure of the Bohai Sea revealed“a relatively normal crust and obviously thinned mantle lid”, local velocity anomalies and instability phenomena in the crust. These features may represent a combined effect of North China-Yangtze collision at an early stage and the remote action of Pacific plate subduction at a late stage.

    Viral hepatitis is currently a major global cause of morbidity and mortality. In some Asian countries like China and Japan, Hepatitis B and C in particular are the most common extremely infectious diseases and are likely to develop into liver cirrhosis. Furthermore, statistics indicate that patients with liver cirrhosis resulting from hepatitis B and C have an increased risk of developing hepatocellular carcinoma (HCC). Scientists have worked tirelessly to find curative therapeutic strategies to control chronic hepatitis and liver cirrhosis, accompanied by improvements in public health and living conditions. China's Shandong University and the University of Tokyo in Japan previously established a longterm cooperative relationship. Cooperative programs include co-training of postgraduates, exchanges of visiting scholars, academic symposia, and a bilateral international joint research program. Some substantive progress has been made as a result of bilateral endeavors. For instance, the Shandong University China-Japan Cooperation Center for Drug Discovery & Screening (SDU-DDSC) has enhanced to serve as an important platform for further close cooperation. At the same time, the International Advancement Center for Medicine & Health Research (IACMHR) - "Drug Discoveries and Therapeutics" and International Research and Cooperation Association for Bio & Socio-Sciences Advancement (IRCA-BSSA) - "BioScience Trends" were established (Visit http://www.ddtjournal.com and http://www.biosciencetrends.com ). The first China-Japan conference on new drug discoveries and therapeutics (CJMWDDT 2007) was recently held in Jinan, China May 27-29, 2007, which provided opportunities for further communication and cooperation and increased knowledge of new drug research and clinical cures for hepatitis.

    The Reduce-Moderation Water Reactor (RMWR) is a next generation water-cooled reactor aiming at effective utilization of uranium resource, high burn-up and long operation cycle, and plutonium multi-recycle. Japan Atomic Energy Research Institute (JAERI) started a joint research program for conceptual design of RMWR core in collaboration with the Japan Atomic Power Company (JAPC) since 1998. The research area includes the RMWR core conceptual designs, development of analysis methods for rector physics and thermal-hydraulics to design the RMWR cores with higher accuracy and preparation of MOX critical experiment to confirm the feasibility from the reactor physics point of view. The present report describes the results of joint research program 'RMWR core design Phase 1' performed by JAERI and JAPC in FY 1998 and 1999. The results obtained from the joint research program are as follows: Conceptual design study on the RMWR core has been performed. A core concept with a conversion ratio more than about 1 is basically feasible to multiple recycling of plutonium. Investigating core characteristics at the equilibrium, some promising core concepts to satisfy above aims have been established. As for BWR-type concepts with negative void reactivity coefficients, three types of design have been obtained as follows; (1) one feasible to attain high conversion ratio about 1.1, (2) one feasible to attain operation cycle of about 2 years and burn-up of about 60 GWd/t with conversion ratio more than 1 or (3) one in simple design based on the ABWR assembly and without blanket attaining conversion ratio more than 1. And as for PWR-type concepts with negative void reactivity coefficients, two types of design have been obtained as follows; (1) one feasible to attain high conversion ratio about 1.05 by using heavy water as a coolant and (2) one feasible to attain conversion ratio about l by using light water.

Category I nuclear material (plutonium and uranium) is used in JINR research reactors, facilities and for scientific and research activities. A monitoring system (MOM) was installed at JINR in April 2003. The system design was based on a vulnerability analysis, which took into account the specifics of the Institute. The design and installation of the MOM system was a collaborative effort between JINR, Brookhaven National Laboratory (BNL) and the U.S. Department of Energy (DOE). Financial support was provided by DOE through BNL. The installed MOM system provides facility management with additional assurance that operations involving nuclear material (NM) are correctly followed by the facility personnel. The MOM system also provides additional confidence that the MPC&A systems continue to perform effectively.

    In an effort to achieve the objectives, the following provisions were made. First of all, the current status of energy industry was carefully reviewed. An increase of energy consumption, both in industrial and home purposes, implored introduction of nuclear power as an alternative energy production source. Secondly, the current status of China's nuclear development programs together with future prospects was reviewed. Through this review, more effective implementation of nuclear cooperative programs could be devised. Thirdly, China's newly developed nuclear infrastructure was analyzed. The re-structuring of the CNNC was reviewed. Based on this analysis, future cooperative programs could be identified. Lastly, proper strategies for future cooperation between the two countries on a complementary basis were studied. Recommendations for better cooperation programs, particularly for the nuclear policy-making process, were presented. For fruitful cooperation, it is naturally needed match funds to support the implementation of joint projects. It is basically China's idea that Korea provides the funds and China provides manpower. China has a great potential market. The Korean Governments support for key funds for cooperative programs will thus have a sincere meaning.

    2014-01-01

    Full Text Available A robust adaptive control method with full-state feedback is proposed based on the fact that the elbow joint of a seven-function hydraulic manipulator with double-screw-pair transmission features the following control characteristics: a strongly nonlinear hydraulic system, parameter uncertainties susceptible to temperature and pressure changes of the external environment, and unknown outer disturbances. Combined with the design method of the back-stepping controller, the asymptotic stability of the control system in the presence of disturbances from uncertain systematic parameters and unknown external disturbances was demonstrated using Lyapunov stability theory. Based on the elbow joint of the seven-function master-slave hydraulic manipulator for the 4500 m Deep-Sea Working System as the research subject, a comparative study was conducted using the control method presented in this paper for unknown external disturbances. Simulations and experiments of different unknown outer disturbances showed that (1 the proposed controller could robustly track the desired reference trajectory with satisfactory dynamic performance and steady accuracy and that (2 the modified parameter adaptive laws could also guarantee that the estimated parameters are bounded.

    JAERI has performed cooperative researches with many Japanese agencies and companies by means of the Halden Boiling Heavy Water Reactor (HBWR) which is located at Halden in Norway. These cooperative researches are carried out based on the contracts of the cooperative researches, which are revised every three years, in accordance with the renewal of the participation of JAERI to the OECD Halden Reactor Project. This report summaries the objectives, contents and the outlines of the achievements of the cooperative researches during the three years from 1994 January to 1996 December. During the period, ten cooperative researches had been carried out, and two of them had finished during the period and other eight researches has been continued to the next three year period. There are many research items, and most of them are irradiation test researches of advanced fuel and cladding concerned with the high burnup utilization of LWR fuel or MOX fuel irradiation researches to prepare for the introduction of Plutonium utilization in LWRs. The researches of fuel irradiation usually take long time because of the characteristics of these kind of research work, and three years are usually not enough to obtain some achievements from the irradiation tests. Therefore, eight tests have been continued after the three year period. In this report, the achievements of the continued researches to the next three year period are not final one but a kind of progress report. (author)

    The U.S.-India Joint Center for Building Energy Research & Development (CBERD), created through the Partnership to Accelerate Clean Energy (PACE) agreement between the United States and India, is a research and development (R&D) center with over 30 institutional and industry partners from both nations. This five-year presidential initiative is jointly funded by the U.S. Department of Energy and the Government of India. CBERD aims to build upon a foundation of collaborative knowledge, tools, and technologies, and human capabilities that will increase development of high-performance buildings. To reach this goal, the R&D focuses on energy use reduction throughout the entire life cycle of buildings—i.e., design, construction, and operations. During the operations phase of buildings, even with best-practice energy-efficient design, actual energy use can be much higher than the design intent. Every day, much of the energy consumed by buildings serves no purpose (Roth et al. 2005). Building energy information systems (EIS) are commercially available systems that building owners and facility managers use to assess their building operations, measure, visualize, analyze, and report energy cost and consumption. Energy information systems can enable significant energy savings by tracking energy use, identifying consumption patterns, and benchmarking performance against similar buildings, thereby identifying improvement opportunities. The CBERD team has identified potential energy savings of approximately 2 quads of primary energy in the United States, while industry building energy audits in India have indicated potential energy savings of up to 30 percent in commercial buildings such as offices. Additionally, the CBERD team has identified healthcare facilities (e.g., hospitals, clinics), hotels, and offices as the three of the highest-growth sectors in India that have significant energy consumption, and that would benefit the most from implementation of EIS.

    The goal of the 2014 Joint Research Target (JRT) has been to conduct experiments and analysis to investigate and quantify the response of tokamak plasmas to non-axisymmetric (3D) magnetic fields. Although tokamaks are conceptually axisymmetric devices, small asymmetries often result from inaccuracies in the manufacture and assembly of the magnet coils, or from nearby magnetized objects. In addition, non-axisymmetric fields may be deliberately applied for various purposes. Even at small amplitudes of order 10-4 of the main axisymmetric field, such “3D” fields can have profound impacts on the plasma performance. The effects are often detrimental (reduction of stabilizing plasma rotation, degradation of energy confinement, localized heat flux to the divertor, or excitation of instabilities) but may in some case be beneficial (maintenance of rotation, or suppression of instabilities). In general, the magnetic response of the plasma alters the 3D field, so that the magnetic field configuration within the plasma is not simply the sum of the external 3D field and the original axisymmetric field. Typically the plasma response consists of a mixture of local screening of the external field by currents induced at resonant surfaces in the plasma, and amplification of the external field by stable kink modes. Thus, validated magnetohydrodynamic (MHD) models of the plasma response to 3D fields are crucial to the interpretation of existing experiments and the prediction of plasma performance in future devices. The non-axisymmetric coil sets available at each facility allow well-controlled studies of the response to external 3D fields. The work performed in support of the 2014 Joint Research Target has included joint modeling and analysis of existing experimental data, and collaboration on new experiments designed to address the goals of the JRT. A major focus of the work was validation of numerical models through quantitative comparison to experimental data, in

    Maman Joyce Dogba

    Full Text Available Despite the growing interest in understanding the psycho-social impact of rare genetic diseases, few studies examine this concept and even fewer seek to obtain feedback from families who have lived the experience. The aim of this project was to involve families of children living with osteogenesis imperfecta (OI in the development of a tool to assess the impact of OI on the lives of patients and their families.This project used an integrated knowledge translation approach in which knowledge users (clinicians and people living with OI and their families were consulted throughout the four steps of development, that is: content mapping, item generation, tool appraisal and pre-testing of the questionnaires. The International Classification of Functioning and Health was used as a framework for content mapping. Based on a scoping review we selected two validated tools to use as a basis for developing the questionnaire. The final parent self-report version measured six domains: experience of diagnosis; use of health services; use of social and psychological support services; expectations about tertiary specialized centers; and socio-demographic information.A total of 27 out of 40 families receiving care at the Shriners Hospital for Children-Canada and invited to participate in the pre-test returned the completed questionnaires. In more than two-thirds of families (69%; n = 18 OI was suspected either at or within the first 3 months after birth.

    The conceptual thermal hydraulics design analyses for the 20 MW reference AHR core have been jointly performed by the KAERI and DNRI(VAEC). The preliminary core thermal hydraulic characteristics and safety margins for the AHR core were studied for various core flow rates, fuel assembly powers and core inlet temperatures. Statistical method was applied to the thermal hydraulic design of the reactor core. The MATRA{sub h} subchannel code has been applied to evaluate the thermal hydraulic performances of the AHR and the resulting thermal margins of the core under the forced convection cooling mode during a nominal power operation and the natural circulation mode during a reactor shutdown condition. In addition, typical accident analyses were carried out for a loss of flow accident by a primary pump seizure and a reactivity induced accident by a CAR rod withdrawal during a normal full power operation. The normal full power operation of the AHR was ensured with a sufficient safety margin for the onset of nucleate boiling phenomena. The AHR also had a sufficient natural circulation cooling capability to cool the core without the onset of nucleate boiling in the channel after a normal reactor shutdown and the anticipated transients. It was confirmed by the typical accident analyses that the AHR core was sufficiently protected from the loss of flow by the primary cooling pump seizure and the overpower transients by the CAR withdrawal from the MCHFR and fuel temperature points of view.

  20. DOE-NE Light Water Reactor Sustainability Program and EPRI Long-Term Operations Program. Joint Research and Development Plan

    Williams, Don

    2014-04-01

    Nuclear power has contributed almost 20% of the total amount of electricity generated in the United States over the past two decades. High capacity factors and low operating costs make nuclear power plants (NPPs) some of the most economical power generators available. Further, nuclear power remains the single largest contributor (nearly 70%) of non-greenhouse gas-emitting electric power generation in the United States. Even when major refurbishments are performed to extend operating life, these plants continue to represent cost-effective, low-carbon assets to the nation’s electrical generation capability. By the end of 2014, about one-third of the existing domestic fleet will have passed their 40th anniversary of power operations, and about one-half of the fleet will reach the same 40-year mark within this decade. Recognizing the challenges associated with pursuing extended service life of commercial nuclear power plants, the U.S. Department of Energy’s (DOE) Office of Nuclear Energy (NE) and the Electric Power Research Institute (EPRI) have established separate but complementary research and development programs (DOE-NE’s Light Water Reactor Sustainability [LWRS] Program and EPRI’s Long-Term Operations [LTO] Program) to address these challenges. To ensure that a proper linkage is maintained between the programs, DOE-NE and EPRI executed a memorandum of understanding in late 2010 to “establish guiding principles under which research activities (between LWRS and LTO) could be coordinated to the benefit of both parties.” This document represents the third annual revision to the initial version (March 2011) of the plan as called for in the memorandum of understanding.

    The Joint Research Centre (JRC) is a Directorate of the European Commission, distributed over sites in Belgium, Germany, Italy, the Netherlands and Spain. Its mission is to provide customer-driven scientific and technical support for the conception, development, implementation and monitoring of EU policies. Peripheral to its fundamental mission are the Decommissioning and radioactive Waste Management (D and WM) activities associated with the JRC nuclear installations constructed and operated during the early years of its research sites. Since the 1980's, the JRC evolving mission has progressively reduced the need for nuclear installations, that must now be decommissioned. The removal of nuclear material from an installation is a prerequisite to start the decommissioning. This paper reports the successful experience at the JRC Italian site (Ispra) on the preparation, packaging and transfer of Plutonium (PuO{sub 2}) and Mixed Oxides (MOX) reference materials used for over twenty years, from the Ispra Performance Laboratory (PERLA) to the original owner abroad. In particular the need for design, licensing and construction of new glove box lines and auxiliary tools as well as the safety provisions for material containers handling and transport are described.

    Technological advances in recent years have allowed the easy and accurate assessment of knee motion during athletic activities. Subsequently, thousands of studies have been published that greatly improved our understanding of the aetiology, surgical reconstruction techniques and prevention of anterior cruciate ligament (ACL) injuries. The purpose of this review is to summarize the evidence from biomechanical studies on ACL-related research. High-impact articles that enhanced understanding of ACL injury aetiology, rehabilitation, prevention and adaptations after reconstruction were selected. The importance of restoring internal tibial rotation after ACL reconstruction has emerged in several studies. Criteria-based, individualized rehabilitation protocols have replaced the traditional time-based protocols. Excessive knee valgus, poor trunk control, excessive quadriceps forces and leg asymmetries have been identified as potential high risk biomechanical factors for ACL tear. Injury prevention programmes have emerged as low cost and effective means of preventing ACL injuries, particularly in female athletes. As a result of biomechanical research, clinicians have a better understanding of ACL injury aetiology, prevention and rehabilitation. Athletes exhibiting neuromuscular deficits predisposing them to ACL injury can be identified and enrolled into prevention programmes. Clinicians should assess ACL-reconstructed patients for excessive internal tibial rotation that may lead to poor outcomes.

  8. Joints in deployable space truss structures

    Since the response of deployable structural concepts being considered for the Large Deployable Reflector (LDR) backup structure will be dominated by the response of joints, the joint characteristics are significant. An overview is given of the research activities at LaRC on the static behavior of joints for deployable space truss structures. Since a pin-clevis-type joint will be utilized in deployable structures, an experimental research program to characterize the joint parameters which affect stiffness was conducted. An experimental research program was conducted on a second type of joint, referred to as a near-center latch joint. It was used in the center of members on the deployable truss structure for the Control of Flexible Structures (COFS) flight experiment. The test results of the near-center latch joint and the member with the joints indicated that the stiffness of the near-center joint is linear and stiffer than the stiffness of the total member, and that non-linearities in the stiffness characteristics of the total member were due to bending introduced at the ends of the member. The resulting data indicates that stiff linear folding joints can be designed and that bending load paths should be avoided whenever possible. In summary, for deployable structures, special attention to the joint and the structure design is required to minimize the undesirable structural non-linearities.

    In chapter 1, the summary of the project is described. The bases of earthquake source modeling are reviewed and discussed in chapter 2. The kinematic source model, which assumes the shape of slip function a priori, with finite extent of fault is very effective and useful model for evaluation of strong ground motions, especially near-fault region. In chapter 3, first, the concept of hazard de-aggregation and an idea of Probabilistic Scenario Earthquakes (PSE) are described. Next, several cases in which PSHA have been practically used are introduced. The case study is demonstrated in which the PSE is applied for the Korean NPP site in order to evaluate dominating earthquakes. In chapter 4, a prototype system for seismic PSA (Probabilistic Safety Assessment) developed is described. And then, a method for generating fragility curves are re- viewed and illustrated based on the review. In addition, a conversion methodology for ground motion index for fragility curve is introduced and the validity of the method is shown. In chapter 5, analysis of ground motions and historical earthquakes in Korea are analyzed. The epicenter depth, dominant period, spectral intensities and so forth are investigated. And also, earthquake activities in Korea based on historical record are investigated. Finally, the conclusions of the research in this year are described.

    Coastal systems are of the most productive ones although they are the most impacted by direct pressures from human activities. These ecosystems exhibit a high level of complexity with many different and interconnected processes operating at various spatial and temporal scales and providing a range of ecosystem services. Coastal observations are tremendous importance in order to understand those complex marine processes. Moreover, they support the use and further development of coastal ocean numerical models, including physical models and coupled physical-biogeochemical models. Coastal data have also many applications in the domain of coastal engineering such as for instance in the design of a coastal structure, or in the prevention of extreme events (e.g. flooding). As a consequence, the number of marine observing systems has quickly increased around European coastal seas, under the pressure of both monitoring requirements and marine research. Present demands for such observing systems include reliable, high-quality and comprehensive observations of key environmental parameters, automated platforms and sensors systems for continuous observations, as well as autonomy over long time periods. In-situ data collected can be combined with remote sensing and/or models to detect, understand and/or forecast the most crucial coastal processes over extensive areas within the various marine environments.

    This paper presents a research into reliability calculations of agriculture double universal joint shafts based on temperature measuring in cardan-type universal joint bearing assemblies. Special laboratory equipment was developed for this research which is presented in the paper. The objective of this research was to test the real life span of universal joint shafts in the laboratory and in field, to obtain the results which can be used to improve the reliability of universal joint shafts. If the presented research were used along with maintenance measures recommended in the paper and with proper use, the level of reliability of the shafts would be 2.1 times higher. The presented results of the research showed that needle bearings, i.e. bearing assemblies of the joints, are the most critical elements on universal joint shafts and are possible causes of their lower reliability. The second universal joint is the part with the lowest reliability in the observed technical system. . (Author)

    This review aimed to inform the current state of alcohol research on the joint effects of genes and the environment conducted in U.S. racial/ethnic minority populations, focusing on African Americans, Latinos/Hispanics, Asians, and American Indians. A key-word and author-based search was conducted and supplemented with direct contact to researchers in this area to ensure a comprehensive inclusion of published, peer-reviewed studies. These studies were considered in terms of the racial/ethnic population groups, phenotypes, genetic variants, and environmental influences covered. Research findings from alcohol epidemiologic studies were highlighted to introduce some potential environmental variables for future studies of gene and environment (G-E) relationships. Twenty-six (N = 26) studies were reviewed. They predominantly involved African American and Asian samples and had a very limited focus on Latinos/Hispanics and American Indians. There was a wide range of alcohol-related phenotypes examined, and studies almost exclusively used a candidate gene approach. Environmental influences focused on the most proximate social network relationships with family and peers. There was far less examination of community- and societal-level environmental influences on drinking. Epidemiologic studies informing the selection of potential environmental factors at these higher order levels suggest inclusion of indicators of drinking norms, alcohol availability, socioeconomic disadvantage, and unfair treatment. The review of current literature identified a critical gap in the study of environments: There is the need to study exposures at community and societal levels. These initial studies provide an important foundation for evolving the dialogue and generating other investigations of G-E relationships in diverse racial/ethnic groups.

    A survey was conducted on the energy situation in Thailand, Indonesia, Malaysia, the Philippines and India, and a possibility of making an international joint research. Thailand has sharply increased investments from Europe and the U.S. since 1985, and has been making a rapid industrialization. As to the energy policy, it is important to secure the stable supply and stabilize the price. Indonesia has been rapidly increasing energy consumption in accordance with the recent economic growth, and is fear of becoming a net oil importing country in the near future. They are taking a policy for securing as much domestic oil and gas as possible. Malaysia has been keeping a high growth of over 8% per year for the past 8 years and rapidly increased energy demand. It is expected that they will maintain a high level of the development of energy resources. In the Philippines, the industrial energy is mostly coal, but electricity expected in future is from the oil-fueled power generation. The stable import of oil is a problem. 45 figs., 51 tabs.

    A joint research had been carried out with a subsidy from the Agency of Natural Resources and Energy since fiscal 1988 to fiscal 1995 on the direct iron ore smelting reduction process (DIOS process). The process utilizes coal directly as a process to use the strong points and supplement the weak points of the blast furnace process. During the period, a pilot plant had been operated since 1993. Upon having completed the feasibility study, this paper reports the result thereof. The main facilities consist of a smelting and reducing furnace of iron bath type, a spare reducing furnace of fluidized bed type, and a preheating furnace. The former two furnaces constitute a unit structure with the two furnaces connected vertically. The pilot plant achieved a three-day continuous operation producing 500 tons of iron every day. The production rate reached 21 tons an hour at an upward oxygen blowing velocity of about 13,000 Nm {sup 3} per hour. The coal unit requirement showed a result of <1000 kg/t for high VM coal and <900 kg/t for low VM coal. These results verified a possibility that this process can supplement or replace the blast furnace process even for a production scale of 9000 tons a day. 7 refs., 15 figs., 3 tabs.

    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)

    The mechanical properties, creep damage, creep rupture strength and features of interfacial failures of welded joints between martensite (SA213T91) and pearlite steel (12Cr1MoV) have been investigated by means of argon tungsten pulsed arc welding, high temperature accelerated simulation, creep rupture, mechanical property tests and scanning electronic microscope (SEM). The research results indicate that the mechanical properties of overmatched and medium matched joint deteriorate obviously, and they are susceptible to creep damage and failure after accelerated simulation operation 500h, in the condition of preheat 250℃, and post welding heat treatment 750℃×1h. However, the mechanical properties of undermatched joint are the best, the interfacial failure tendency of undermatched welded joint is less than those of medium and overmatched welded joint. Therefore, it is reasonable that low alloy material TR31 is used as the filler metal of weld between SA213T91and 12Cr1MoV steel.

    Previous research has shown that interpersonal coordination enhances pro-social attitudes and behavior. Here, we extend this research by investigating whether the degree of coordination observed in a joint action enhances the perception of individuals' commitment to the joint action. In four experiments, participants viewed videos of joint actions. In the low coordination condition, two agents made independent individual contributions to a joint action. In the high coordination condition, the individual contributions were tightly linked. Participants judged whether and for how long the observed agents would resist a tempting outside option and remain engaged in the joint action. The results showed that participants were more likely to expect agents to resist outside options when observing joint actions with a high degree of coordination. This indicates that observing interpersonal coordination is sufficient to enhance the perception of commitment to joint action. Copyright © 2016 Elsevier B.V. All rights reserved.

  4. Model Test Research on the End Bearing Behavior of the Large-Diameter Cast-in-Place Concrete Pile for Jointed Rock Mass

    2016-01-01

    Full Text Available For large-diameter, cast-in-place concrete piles, the end bearing capacity of a single pile is affected by discontinuous surfaces that exist in natural rock masses when the bearing layer of the pile end is located in the rock layer. In order to study the influence of the jointed dip angle on the bearing characteristics of the pile end, the discrete element models are adopted to simulate the mechanical characteristics of the jointed rock masses, and the model tests of the failure mode of the jointed rock masses were also designed. The results of the numerical calculations and modeling tests show that the joints, which have a filtering effect on the internal stress of the bedrock located at the pile end, change the load transferring paths. And the failure mode of the jointed rock foundation also changes as jointed dip angle changes. The rock located at the pile end generally presents a wedge failure mode. In addition, the Q-S curves obtained by model tests show that the ultimate end bearing capacity of a single pile is influenced by the jointed dip angle. The above results provide an important theoretical basis for how to correctly calculate end resistance for a cast-in-place concrete pile.

    The activities implemented jointly (AIJ) is expected as global measures to reduce greenhouse gas (such as CO2) emission. In this report, the possibility of AIJ projects in developing countries was researched. The United Nations Framework Convention on Climate Change was signed by 155 countries in 1992. This convention parties approved AIJ projects for measures against global warming. The 1st Conference of the Parties (COPI) held in 1995 approved the pilot phase of AIJ by voluntary workers jointly with developing countries until the end of this century. The trend, level and future plan of energy conservation technologies were researched and analyzed for steelmaking, cement and electric power supply industries in both the Philippine and Thailand. The possibility of AIJ projects was studied by selecting several Japanese energy conservation technologies transferable to both countries. The same research was also carried out for forest as carbon absorption source. 5 refs., 23 figs., 58 tabs.

    In November of 2009, the presidents of China and the U.S. announced the establishment of the Clean Energy Research Center (CERC). This broad research effort is co-funded by both countries and involves a large number of research centers and universities in both countries. One part of this program is focused on improving the energy efficiency of buildings. One portion of the CERC-BEE was focused on building insulation systems. The research objective of this effort was to Identify and investigate candidate high performance fire resistant building insulation technologies that meet the goal of building code compliance for exterior wall applications in green buildings in multiple climate zones. A Joint Work Plan was established between researchers at the China Academy of Building Research and Oak Ridge National Laboratory. Efforts in the first year under this plan focused on information gathering. The objective of this research program is to reduce building energy use in China via improved building insulation technology. In cold regions in China, residents often use inefficient heating systems to provide a minimal comfort level within inefficient buildings. In warmer regions, air conditioning has not been commonly used. As living standards rise, energy consumption in these regions will increase dramatically unless significant improvements are made in building energy performance. Previous efforts that defined the current state of the built environment in China and in the U.S. will be used in this research. In countries around the world, building improvements have typically followed the implementation of more stringent building codes. There have been several changes in building codes in both the U.S. and China within the last few years. New U.S. building codes have increased the amount of wall insulation required in new buildings. New government statements from multiple agencies in China have recently changed the requirements for buildings in terms of energy efficiency and

    From July 20 to August 2, 2008, joint activities sponsored by the Canadian Space Agency (CSA - Space Learning) and NASA (Spaceward Bound) were carried out at the McGill Arctic Research Station (MARS) in the Canadian High Arctic. Established in 1960, MARS consists of two sites located on western Axel Heiberg Island along the shore of Expedition Fiord (lower camp), and 8 km inland, at Colour Lake (upper camp). The MARS upper camp is one of the longest-operating seasonal field research facilities in polar regions. The lower camp was established in 2007 through infrastructure support provided by the CSA. The station is located in a mountainous area dominated by ice caps, outlet and valley glaciers, polar desert, arctic tundra, and permafrost, and is internationally recognized for research on cold, perennial springs associated with the presence of evaporite domes. Six educators from the U.S. and Canada participated in field surveys and hands-on demonstrations with the following objectives: (1) join a team of scientists and engineers to explore the topics of Physical Geography, Geoscience, Astrobiology, and Robotics through experiential learning; (2) discover how remote and extreme polar environments on Earth are used by planetary scientists to better understand the evolution of the Moon and Mars, and to potentially train future planetary explorers; (3) bring that experience back to their classrooms, and assist in the development of space curriculum related to science, technology, and engineering projects carried out at planetary analogue sites. In this paper, we present a summary of operational planning and field surveys that led to successful scientific experiments by 16 participants during the Expedition. Research topics explored prior to, and during the arctic mission include Physical Geography, Geomorphology, Geology, Seismology, Earth Observation, Astrobiology, and Terrain Characterization with implications for future human and robotic exploration missions to the

    Science.gov (United States)

    Johnson, K.; Kim, R.; Echeverry, J.

    The Joint Space Operations Center (JSpOC) is a command and control center focused on executing the Space Control mission of the Joint Functional Component Command for Space (JFCC-SPACE) to ensure freedom of action of United States (US) space assets, while preventing adversary use of space against the US. To accomplish this, the JSpOC tasks a network of space surveillance sensors to collect Space Situational Awareness (SSA) data on resident space objects (RSOs) in near earth and deep space orbits. SSA involves the ingestion of data sources and use of algorithms and tools to build, maintain, and disseminate situational awareness of RSOs in space. On the heels of emergent and complex threats to space assets, the JSpOC's capabilities are limited by legacy systems and CONOPs. The JSpOC Mission System (JMS) aims to consolidate SSA efforts across US agencies, international partners, and commercial partners. The JMS program is intended to deliver a modern service-oriented architecture (SOA) based infrastructure with increased process automation and improved tools to remove the current barriers to JSpOC operations. JMS has been partitioned into several developmental increments. Increment 1, completed and operational in early 2013, and Increment 2, which is expected to be completed in 2016, will replace the legacy Space Defense Operations Center (SPADOC) and Astrodynamics Support Workstation (ASW) capabilities. In 2017 JMS Increment 3 will continue to provide additional SSA and C2 capabilities that will require development of new applications and procedures as well as the exploitation of new data sources. Most importantly, Increment 3 is uniquely postured to evolve the JSpOC into the centralized and authoritative source for all Space Control applications by using its SOA to aggregate information and capabilities from across the community. To achieve this goal, Scitor Corporation has supported the JMS Program Office as it has entered into a partnership with AFRL/RD (Directed

In order to overcome the problem,we present an additional robust control law in conjunction with the adaptive design procedure ,with the known boundary of model error,it realizes selfadaptive control for flexible-joint robots with unknown model parameter. Compared with most of the available control schemes for flexible joint robot system that assume weak joint flexibility or knowledge of joint accelerations ,the proposed control law guarantees global stability of the robot manipulators with uncertain joint flexibility without recourse to any joint acceleration or jerk measurements

Big holes were cut in the steel tubular wall of core area of the joint. Compared with the joint which small holes were set in the steel tubular wall for steel bar running through, the new type joint was more easily to be constructed. And a transient joint was made to characterize with big holes and strengthening ring and stiffing ribs. Low cycle fatigue tests were implemented to analysis these three joints and the following conclusions were given; the displacement ductility and the ability of energy dissipation of this new type joint are more ideal and seismic behavior is better which all satisfied the requirement of the structural seismic design. The stiffening ring and stiffing ribs fixed on the joint both can improve its integrity and ductility significantly. Research results can provide theoretical and experimental reference to the engineering application.

    Full Text Available Due to Challenger space shuttle accident in 1986, significant research has been done concerning structural behavior of field joints in solid rocket boosters (SRB. The structural deformations between the clevis inner leg and the tang (male-to-female parts of joint, the sealing of the O-ring to prevent the hot gas in joints, has been neglected causing the failure of the vehicle. Redesigning the field joint in SRB engine by accurate analysis of dynamic and thermal loads and by design of insulator and good O-ring, the leakiness of combustion hot gases was eliminated. Some parts of field joint such as capture feature (CF and its third O-ring, J-leg insulator and shim were added to redesigned field joint. Also, some adjustments in sealing system and pins were done to promote the efficiency of the field joint. Due to different experimental analysis on assembled field joints with default imperfections, redesigned joints operated well. These redesigned field joints are commonly used in aerospace and mechanical structures. This paper investigates the original and the redesigned field joints with additional explanations of different parts of the redesigned joints.

    The Quick Urban & Industrial Complex (QUIC) atmospheric transport, and dispersion modelling, system was evaluated against the Joint Urban 2003 tracer-gas measurements. This was done using the wind and turbulence fields computed by the Weather Research and Forecasting (WRF) model. We compare the simulated and observed plume transport when using WRF-model-simulated wind fields, and local on-site wind measurements. Degradation of the WRF-model-based plume simulations was cased by errors in the simulated wind direction, and limitations in reproducing the small-scale wind-field variability. We explore two methods for importing turbulence from the WRF model simulations into the QUIC system. The first method uses parametrized turbulence profiles computed from WRF-model-computed boundary-layer similarity parameters; and the second method directly imports turbulent kinetic energy from the WRF model. Using the WRF model's Mellor-Yamada-Janjic boundary-layer scheme, the parametrized turbulence profiles and the direct import of turbulent kinetic energy were found to overpredict and underpredict the observed turbulence quantities, respectively. Near-source building effects were found to propagate several km downwind. These building effects and the temporal/spatial variations in the observed wind field were often found to have a stronger influence over the lateral and vertical plume spread than the intensity of turbulence. Correcting the WRF model wind directions using a single observational location improved the performance of the WRF-model-based simulations, but using the spatially-varying flow fields generated from multiple observation profiles generally provided the best performance.

  18. The prospects for using (Q)SARs in a changing political environment--high expectations and a key role for the European Commission's joint research centre.

    Worth, A P; Van Leeuwen, C J; Hartung, T

    2004-01-01

    Recent policy developments in the European union (EU) and within the Organisation for Economic Cooperation and Development (OECD) have placed increased emphasis on the use of structure-activity relationships (SARs) and quantitative structure-activity relationships (QSARs), collectively referred to as (Q)SARs, within various regulatory programmes for the assessment of chemicals and products. The most significant example within the EU is the European commission's proposal (of 29 October 2003) to introduce a new system for managing chemicals (called REACH), which calls for an increased use of (Q)SARs and other non-animal methods, especially for the assessment of low production volume chemicals. Another development within the EU is the Seventh Amendment to the Cosmetics Directive, which foresees the phasing out of animal testing on cosmetics, combined with the imposition of marketing bans on cosmetics that have been tested on animals after certain deadlines. At the same time, the Existing Chemicals programme within the OECD is investigating ways of increasing the use of chemical category approaches, which depend heavily on the use of (Q)SARs, activity-activity relationships and read-across. Such developments are placing an enormous challenge on industry, regulatory bodies, and on the European commission's Joint Research Centre (JRC), which is responsible for providing independent scientific advice to policy makers in the European Commission and the Member States. This paper reviews the different scientific and regulatory purposes for which reliable (Q)SARs could be used, and describes the current work of the JRC in providing scientific support for the development, validation and implementation of (Q)SARs.

    Pressure suit mobility joints are for use in interconnecting adjacent segments of an hermetically sealed spacesuit in which low torques, low leakage and a high degree of reliability are required. Each of the joints is a special purpose joint characterized by substantially constant volume and low torque characteristics and includes linkages which restrain the joint from longitudinal distension and includes a flexible, substantially impermeable diaphragm of tubular configuration spanning the distance between pivotally supported annuli. The diaphragms of selected joints include rolling convolutions for balancing the joints, while various joints include wedge-shaped sections which enhance the range of motion for the joints.

The joint study with an Indonesian research institute takes a model of lumber drying plant for the design and feasibility study. All the parts it needs are technically available in Indonesia, except carbon fiber sheets and electronic devices for controlling purposes. The drying cost is higher than that of a plant which procures charge-free wood fuel, but lower than that of a plant which procures fuel at 30$/t. A cacao drying plant model is also studied. The feasibility study shows that the initial investment for the blowing-up model is much higher by 60% to 100% than that for the conventional plant. Its fuel cost is lower by 11% than that of residual oil but 27% higher than that of wood. 4 figs.

    The above-mentioned effort is to comply with the COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change) joint implementation clause. At this coal field, mining facilities are growing superannuated and obsolescent in the prolonged business depression, causing frequent occurrence of disasters such as gas explosions. The coal mine gas collection rate at the Kuznetsk coal field is as low as 17%, with concern for safety discouraging sufficient collection. Even the small amount of the collected gas is, in the absence of gas utilizing facilities, totally discharged into the air. For the mitigation of global warming, for mining safety, and for the establishment of a foundation for business, it is desired that coal mine methane gas collection/utilization facilities and related technologies be introduced into the coal field. Gas purging from the pits is incomplete, which is attributed to the lack of equipment capable of excavating proper-diameter bores longer than 100m for longwall mining. Ventilation also needs improvement. The research is under way on the premise that highly reliable intermediate range (300m) boring equipment and gas management technologies will be available. Collection of gas of a 30-35% concentration level at a collection rate of 40% is the target. (NEDO)

    This review article addresses the best evidence currently available for therapeutic injection therapy for conditions targeting the spine and sacroiliac joints. The article is presented by spinal region. Controversies and areas of interest for further studies are identified. There is conclusive evidence supporting the effectiveness of the caudal approach for the administration of epidural steroid injections for patients with low back pain from a variety of causes. In general, there is moderate-to-strong evidence supporting the use of transforaminal therapeutic epidural injections for lumbar nerve-root compression and facet injections for joint pain arising from these joints in the cervical, thoracic and lumbar spine, but further subgroup analysis is needed to help predict which specific patients may receive the most benefit from these procedures. No randomized controlled trials, meta-analyses or systematic reviews addressing the effectiveness of therapeutic sacroiliac joint injections have been found. For some injections, corticosteroids may not provide better outcomes compared to local anesthetic injections alone. (orig.)

    The tropical forest regeneration technology research group of Kansai Electric Power Company and Kansai Environment Center has been performing the research and development of tropical forest regeneration technology jointly with Indonesia since fiscal 1992. The group was awarded with the Global Environment Technology Prize from Nihon Keizai Shimbun, Inc. As a result of stringent examination on 97 applications, being two times as many as in usual years, the group received high evaluation on the originality, reality and possibility of proliferation of its research, and impacts given to the societies. Two other groups were also selected. The achievements were reported by the representative of the group in the award commemoration lecture at the global environment economist summit held by the Nikkei press the same day. Conventionally, afforestation done with considerable efforts has often been lost by forest fires and slash-and-burn farming, whereas the present research aims at establishing a comprehensive afforestation technology considering social and economic aspects, and CO2 fixation. As one of the choices of flexible measures as a result of the effect of forests having been recognized in COP3, frameworks for utilizing the mechanisms of joint implementation and clean resource development were introduced. Ever increasing expectations are placed on the achievements of the present research works. (NEDO)

    Use of unmanned systems is rapidly growing within the military and civilian sectors in a variety of roles including reconnaissance, surveillance, explosive ordinance disposal (EOD), and force-protection and perimeter security. As utilization of these systems grows at an ever increasing rate, the need for unmanned systems teaming and inter-system collaboration becomes apparent. Collaboration provides a means of enhancing individual system capabilities through relevant data exchange that contributes to cooperative behaviors between systems and enables new capabilities not possible if the systems operate independently. A collaborative networked approach to development holds the promise of adding mission capability while simultaneously reducing the workload of system operators. The Joint Collaborative Technology Experiment (JCTE) joins individual technology development efforts within the Air Force, Navy, and Army to demonstrate the potential benefits of interoperable multiple system collaboration in a force-protection application.

  14. Solder joint technology materials, properties, and reliability

    2007-01-01

    Solder joints are ubiquitous in electronic consumer products. The European Union has a directive to ban the use of Pb-based solders in these products on July 1st, 2006. There is an urgent need for an increase in the research and development of Pb-free solders in electronic manufacturing. For example, spontaneous Sn whisker growth and electromigration induced failure in solder joints are serious issues. These reliability issues are quite complicated due to the combined effect of electrical, mechanical, chemical, and thermal forces on solder joints. To improve solder joint reliability, the science of solder joint behavior under various driving forces must be understood. In this book, the advanced materials reliability issues related to copper-tin reaction and electromigration in solder joints are emphasized and methods to prevent these reliability problems are discussed.

  15. Using Joint Interviews to Add Analytic Value.

    Polak, Louisa; Green, Judith

    2016-10-01

    Joint interviewing has been frequently used in health research, and is the subject of a growing methodological literature. We review this literature, and build on it by drawing on a case study of how people make decisions about taking statins. This highlights two ways in which a dyadic approach to joint interviewing can add analytic value compared with individual interviewing. First, the analysis of interaction within joint interviews can help to explicate tacit knowledge and to illuminate the range of often hard-to-access resources that are drawn upon in making decisions. Second, joint interviews mitigate some of the weaknesses of interviewing as a method for studying practices; we offer a cautious defense of the often-tacit assumption that the "naturalness" of joint interviews strengthens their credibility as the basis for analytic inferences. We suggest that joint interviews are a particularly appropriate method for studying complex shared practices such as making health decisions.

  19. The Planar Shape of Rock Joints

    2010-02-01

    Knowing the planar shape of discontinuities is important when characterizing discontinuities in a rock mass. However, the real discontinuity shape is rarely known, since the rock mass is usually inaccessible in three dimensions. Information on discontinuity shape is limited and often open to more than one interpretation. This paper discusses the planar shape of rock joints, the most common discontinuities in rock. First, a brief literature review about the shape of joints is presented, including some information on joint-surface morphology, inferences from observed trace lengths on different sampling planes, information based on experimental studies, and joint shapes assumed by different researchers. This review shows that joints not affected by adjacent geological structures such as bedding boundaries or pre-existing fractures tend to be elliptical (or approximately circular but rarely). Joints affected by or intersecting such geological structures tend to be rectangular. Then, using the general stereological relationship between trace length distributions and joint size distributions developed by Zhang et al. (Geotechnique 52(6):419-433, 2002) for elliptical joints, the effect of sampling plane orientation on trace lengths is investigated. This study explains why the average trace lengths of non-equidimensional (elliptical or similar polygonal) joints on two sampling planes can be about equal and thus the conclusion that rock joints are equidimensional (circular) drawn from the fact that the average trace lengths on two sampling planes are approximately equal can be wrong. Finally, methods for characterizing the shape and size of joints (elliptical or rectangular) from trace length data are recommended, and the appropriateness of using elliptical joint shapes to represent polygonal, especially rectangular, joints is discussed.

    Long-term stability of emplacement drifts and potential near-field fluid flow resulting from coupled effects are among the concerns for safe disposal of high-level nuclear waste (HLW). A number of factors can induce drift instability or change the near-field flow patterns. Repetitive seismic loads from earthquakes and thermal loads generated by the decay of emplaced waste are two significant factors. One of two key technical uncertainties (KTU) that can potentially pose a high risk of noncompliance with the performance objectives of 10 CFR Part 60 is the prediction of thermal-mechanical (including repetitive seismic load) effects on stability of emplacement drifts and the engineered barrier system. The second KTU of concern is the prediction of thermal-mechanical-hydrological (including repetitive seismic load) effects on the host rock surrounding the engineered barrier system. The Rock Mechanics research project being conducted at the Center for Nuclear Waste Regulatory Analyses (CNWRA) is intended to address certain specific technical issues associated with these two KTUs. This research project has two major components: (i) seismic response of rock joints and a jointed rock mass and (ii) coupled thermal-mechanical-hydrological (TMH) response of a jointed rock mass surrounding the engineered barrier system (EBS). This final report summarizes the research activities concerned with the repetitive seismic load aspect of both these KTUs.

    Full Text Available This paper presents a research into reliability calculations of agriculture double universal joint shafts based on temperature measuring in cardan-type universal joint bearing assemblies. Special laboratory equipment was developed for this research which is presented in the paper. The objective of this research was to test the real life span of universal joint shafts in the laboratory and in field, to obtain the results which can be used to improve the reliability of universal joint shafts. If the presented research were used along with maintenance measures recommended in the paper and with proper use, the level of reliability of the shafts would be 2.1 times higher. The presented results of the research showed that needle bearings, i.e. bearing assemblies of the joints, are the most critical elements on universal joint shafts and are possible causes of their lower reliability. The second universal joint is the part with the lowest reliability in the observed technical system.

    What constitutes jointly Poisson processes remains an unresolved issue. This report reviews the current state of the theory and indicates how the accepted but unproven model equals that resulting from the small time-interval limit of jointly Bernoulli processes. One intriguing consequence of these models is that jointly Poisson processes can only be positively correlated as measured by the correlation coefficient defined by cumulants of the probability generating functional.

    Stress intensity factors (SIFs) for weld root crack of T-butt joints are researched. Semi-ellipse crack models for weld root of T-butt joints are built with finite model. Geometric parameters and boundary conditions are established according to finite model. Singular element method is used to simulate stress singularity of crack tip with finite element calculation. Element size of crack tip is obtained by convergence experiment. Calculation results show that, SIFs of crack tip have regularity for different initial crack size under same load, and the importance of different geometric parameters affect SIF is different. Therefore, some geometric parameters must be focused on fatigue research for weld root of T-butt joint. The simulation results are fitted by multiple linear regression method. These results could provide a valuable reference for further research of crack propagation and fatigue life prediction.%建立T形焊接接头根部裂纹的半椭圆裂纹模型,定义裂纹模型的构形参数以及边界条件,分析裂纹尖端的应力强度因子.采用奇异单元法,通过有限元计算,模拟裂纹尖端的应力奇异性.并通过收敛性检验确定裂纹尖端的单元尺寸.在此基础上,计算裂纹尖端量纲一应力强度因子,并分析其受几何参数影响的变化规律.计算结果表明,对于给定的载荷条件下,不同初始裂纹尺寸时,裂纹尖端的应力强度因子存在一定的规律性,且不同几何参数对应力强度因子的影响程度存在一定差异,因此,对焊接结构疲劳强度研究时需要有一定的侧重点.采用多重线性回归方法拟合仿真计算结果,这些结果为进一步研究T形焊接接头根部裂纹扩展和疲劳寿命预测提供参考.

  19. Mechanics of Sheeting Joints

    Science.gov (United States)

    Martel, S. J.

    2015-12-01

    Physical breakdown of rock across a broad scale spectrum involves fracturing. In many areas large fractures develop near the topographic surface, with sheeting joints being among the most impressive. Sheeting joints share many geometric, textural, and kinematic features with other joints (opening-mode fractures) but differ in that they are (a) discernibly curved, (b) open near the topographic surface, and (c) form subparallel to the topographic surface. Where sheeting joints are geologically young, the surface-parallel compressive stresses are typically several MPa or greater. Sheeting joints are best developed beneath domes, ridges, and saddles; they also are reported, albeit rarely, beneath valleys or bowls. A mechanism that accounts for all these associations has been sought for more than a century: neither erosion of overburden nor high lateral compressive stresses alone suffices. Sheeting joints are not accounted for by Mohr-Coulomb shear failure criteria. Principles of linear elastic fracture mechanics, together with the mechanical effect of a curved topographic surface, do provide a basis for understanding sheeting joint growth and the pattern sheeting joints form. Compressive stresses parallel to a singly or doubly convex topographic surface induce a tensile stress perpendicular to the surface at shallow depths; in some cases this alone could overcome the weight of overburden to open sheeting joints. If regional horizontal compressive stresses, augmented by thermal stresses, are an order of magnitude or so greater than a characteristic vertical stress that scales with topographic amplitude, then topographic stress perturbations can cause sheeting joints to open near the top of a ridge. This topographic effect can be augmented by pressure within sheeting joints arising from water, ice, or salt. Water pressure could be particularly important in helping drive sheeting joints downslope beneath valleys. Once sheeting joints have formed, the rock sheets between

  1. A study of sandwich T-joints and composite lap joints

    Science.gov (United States)

    Turaga, Umamaheswar V. R. S.

    In this study, new efficient designs for adhesive sandwich T-joint and single-lap joint were proposed and investigated. In the proposed new sandwich T-joint, called U-channel joint, the load transfer path at the web-flange interface was modified to include a U-shaped aluminum channel which provides strong path for load transfer. Experimental results show that the new design has 62% more strength than the conventional circular fillet joint. The new U-channel joint was tested in tension, compression and bending to investigate its characteristics. It is found to have good performance in bending also, even though in compression it performs same as the circular fillet joint. An extensive parametric study was carried out to investigate the effect of parameters like flange skin stiffener, foam density, foam thickness in the web, and aluminum attachments. A fracture mechanics criterion based on the strain energy release rate was used to explain the failure modes, apart from the stress analysis explanation. The failure loads of the joints in compression were predicted using a maximum principal stress failure criterion based on the sandwich beam theory. A new single lap joint with attachments was proposed in the second phase of the research. The design was verified using both aluminum and composite materials. The new design was found to have 59% more strength than the single-lap joint. A parametric study was performed to find out the influence of the angle of attachment, thickness of attachment and the length of attachment. By careful consideration of design parameters, the joint can be optimized. Finally, the failure loads of the single lap joints with and without attachments were predicted using different failure criteria.

    The purposes of this study were to evaluate the relationship between correlation of MR joint effusion of the temporomandibular joint and disk position, to evaluate the relationship between joint effusion and aging, and to assess the frequency of MR joint effusion of bilateral temporomandibular joints. The temporomandibular joints of 192 patients with clinical symptoms of temporomandibular joint disorders were imaged bilaterally using high field, surface-coil MR imaging. Oblique sagittal and coronal proton density-weighted and T2-weighted images were obtained. Imaging findings of joint effusion were correlated with disk position, aging, and bilateral temporomandibular joints. MR showed effusion in 4% of the joints with normal superior disk position, 36% of the joints with disk displacement with reduction, and 45% of the joints with disk displacement without reduction. There were significant differences in the incidence of joint effusion between normal disk position and anterior disk displacement with or without reduction. Younger patients less than 40 years were significant higher the incidence of joint effusion than those of older patients. A significant association was seen between joint effusion and aging. MR showed effusion in 17% of the unilateral temporomandibular joint, 24% of the bilateral temporomandibular joints. There was no significant difference between unilateral and bilateral case. These results indicated that joint effusion using MR imaging was associated with varied temporomandibular joint pathologic states. (author)

    2015-01-01

    The present review will give an update on temporomandibular joint (TMJ) imaging using CBCT. It will focus on diagnostic accuracy and the value of CBCT compared with other imaging modalities for the evaluation of TMJs in different categories of patients; osteoarthritis (OA), juvenile OA, rheumatoid arthritis and related joint diseases, juvenile idiopathic arthritis and other intra-articular conditions. Finally, sections on other aspects of CBCT research related to the TMJ, clinical decision-making and concluding remarks are added. CBCT has emerged as a cost- and dose-effective imaging modality for the diagnostic assessment of a variety of TMJ conditions. The imaging modality has been found to be superior to conventional radiographical examinations as well as MRI in assessment of the TMJ. However, it should be emphasized that the diagnostic information obtained is limited to the morphology of the osseous joint components, cortical bone integrity and subcortical bone destruction/production. For evaluation of soft-tissue abnormalities, MRI is mandatory. There is an obvious need for research on the impact of CBCT examinations on patient outcome. PMID:25369205

  4. The joint flanker effect and the joint Simon effect: On the comparability of processes underlying joint compatibility effects.

    Previous studies observed compatibility effects in different interference paradigms such as the Simon and flanker task even when the task was distributed across two co-actors. In both Simon and flanker tasks, performance is improved in compatible trials relative to incompatible trials if one actor works on the task alone as well as if two co-actors share the task. These findings have been taken to indicate that actors automatically co-represent their co-actor's task. However, recent research on the joint Simon and joint flanker effect suggests alternative non-social interpretations. To which degree both joint effects are driven by the same underlying processes is the question of the present study, and it was scrutinized by manipulating the visibility of the co-actor. While the joint Simon effect was not affected by the visibility of the co-actor, the joint flanker effect was reduced when participants did not see their co-actors but knew where the co-actors were seated. These findings provide further evidence for a spatial interpretation of the joint Simon effect. In contrast to recent claims, however, we propose a new explanation of the joint flanker effect that attributes the effect to an impairment in the focusing of spatial attention contingent on the visibility of the co-actor.

    ue to the contradiction of water storage and sediment releasing in reservoir operation, and the long-term comprehensive targets which include flood control, power generation, shipping and so on, the water and sediment joint multi-objective optimization of scheduling model is established with multi-objective decision-making methods. In flood season, the principle of hierarchical flow is used to control the water level. The hierarchical flow and the corresponding operating water level should be set. Then we calculate the generated energy of the reservoir, the sediment volume and the long-term comprehensive benefits with considering the constraints. Finally, the model is applied to integrated operation of Three Gorges Reservoir. According to the operating water level which is correspond to the principle the hierarchical flow, we run the model in 50-years flood seasons. The results show that the overall efficiency increases by 6. 324%, 5. 559% in electricity generation while the sedimentation rate increases by only 0. 148%. So. We can say that the mode of hierarchical flow in joint operation of water and sediment during flood season can give full play to the comprehensive benefit of Three Gorges Reservoir.%针对水库运行中蓄水与排沙的矛盾,兼顾水库防洪、发电、航运及长期利用的综合运用目标,利用多目标决策方法建立了水库水沙多目标联合优化调度模型,即汛期采用分级流量原则控制水位运行,制定分级流量与对应的运行水位,通过水库发电调度与泥沙冲淤计算的耦合,计算在约束条件下水库的发电量、泥沙淤积量及长期综合效益.将该模型应用于三峡水库综合运行研究中,汛期按分级流量原则控制水位运行50年.计算结果表明,与原设计水位运行方式相比,汛期分级流量运行的综合效益增加6.324%、发电量增加5.559%、泥沙淤积量仅增加0.148%,可见水沙联合调度的汛期分级流量运行方式能充分

    Brain neuroimaging has been widely used to investigate the bran signature of chronic orofacial pain, including trigeminal neuropathic pain (TNP) and pain related to temporomandibular joint disorders (TMD). We here systematically reviewed the neuroimaging literature regarding the functional and structural changes in the brain of TNP and TMD pain patients, using a computerized search of journal articles via PubMed. Ten TNP studies and 14 TMD studies were reviewed. Study quality and risk of bias were assessed based on the criteria of patient selection, the history of medication, the use of standardized pain/psychological assessments, and the model and statistics of imaging analyses. Qualitative meta-analysis was performed by examining the brain regions which showed significant changes in either brain functions (including the blood-oxygen-level dependent signal, cerebral blood flow and the magnetic resonance spectroscopy signal) or brain structure (including gray matter and white matter anatomy). We hypothesized that the neuroimaging findings would display a common pattern as well as distinct patterns of brain signature in the disorders. This major hypothesis was supported by the following findings: (1) TNP and TMD patients showed consistent functional/structural changes in the thalamus and the primary somatosensory cortex, indicating the thalamocortical pathway as the major site of plasticity. (2) The TNP patients showed more alterations at the thalamocortical pathway, and the two disorders showed distinct patterns of thalamic and insular connectivity. Additionally, functional and structural changes were frequently reported in the prefrontal cortex and the basal ganglia, suggesting the role of cognitive modulation and reward processing in chronic orofacial pain. The findings highlight the potential for brain neuroimaging as an investigating tool for understanding chronic orofacial pain.

    1985-01-01

    The structure and policies governing joint appointments discussed above, are developed primarily through cooperation and collaboration between nursing service and education institutions. The joint appointee participates in the process of negotiation of salary, benefits and role responsibilities and exploration of the implications of the appointment for personal career development. Implementation and maintenance of the appointment requires the collaborative efforts of the joint appointee with both contracting agencies. Factors influencing the functioning of joint appointees have been identified and strategies to facilitate functioning presented. The joint appointee must be independent in thought and action yet adaptable to work within the boundaries of two social systems with differing values and expectations. Nursing management, peers and students can provide the support needed to overcome the frustrations and to achieve the rewards inherent in successful implementation of an exciting and innovative role.

    2011-01-01

    Full Text Available Modelling of joint properties of lower limbs in people with spinal cord injury is significantly challenging for researchers due to the complexity of the system. The objective of this study is to develop a knee joint model capable of relating electrical parameters to dynamic joint torque as well as knee angle for functional electrical stimulation application. The joint model consists of a segmental dynamic, time-invariant passive properties and uncertain time-variant active properties. The knee joint model structure comprising optimised equations of motion and fuzzy models to represent the passive viscoelasticity and active muscle properties is formulated. The model thus formulated is optimised using genetic optimization, and validated against experimental data. The developed model can be used for simulation of joint movements as well as for control development. The results show that the model developed gives an accurate dynamic characterisation of the knee joint.

  1. Total ankle joint replacement.

    Science.gov (United States)

    2016-02-01

    Ankle arthritis results in a stiff and painful ankle and can be a major cause of disability. For people with end-stage ankle arthritis, arthrodesis (ankle fusion) is effective at reducing pain in the shorter term, but results in a fixed joint, and over time the loss of mobility places stress on other joints in the foot that may lead to arthritis, pain and dysfunction. Another option is to perform a total ankle joint replacement, with the aim of giving the patient a mobile and pain-free ankle. In this article we review the efficacy of this procedure, including how it compares to ankle arthrodesis, and consider the indications and complications.

    The JSpOC Mission System is a modern service-oriented architecture (SOA) infrastructure with increased process automation and improved tools to enhance Space Situational Awareness (SSA). The JMS program has already delivered Increment 1 in April 2013 as initial capability to operations. The programs current focus, Increment 2, will be completed by 2016 and replace the legacy Space Defense Operations Center (SPADOC) and Astrodynamics Support Workstation (ASW) capabilities. Post 2016, JMS Increment 3 will continue to provide additional SSA and C2 capabilities that will require development of new applications and procedures as well as the exploitation of new data sources with more agility. In 2012, the JMS Program Office entered into a partnership with AFRL/RD (Directed Energy) and AFRL/RV (Space Vehicles) to create the Advanced Research, Collaboration, and Application Development Environment (ARCADE). The purpose of the ARCADE is to: (1) serve as a centralized testbed for all research and development (R&D) activities related to JMS applications, including algorithm development, data source exposure, service orchestration, and software services, and provide developers reciprocal access to relevant tools and data to accelerate technology development, (2) allow the JMS program to communicate user capability priorities and requirements to developers, (3) provide the JMS program with access to state-of-the-art research, development, and computing capabilities, and (4) support market research efforts by identifying outstanding performers that are available to shepherd into the formal transition process. AFRL/RV and AFRL/RD have created development environments at both unclassified and classified levels that together allow developers to develop applications and work with data sources. The unclassified ARCADE utilizes the Maui high performance computing (HPC) Portal, and can be accessed using a CAC or Kerberos using Yubikey. This environment gives developers a sandbox

Entering and developing presence in emerging markets often require foreign firms to set up International Joint Ventures (IJVs) with local partners...... their expectations. Inter-partner learning has been proposed in the literature as a major cause of IJV instability. However, current research indicates that when IJV partners engage in joint learning to create new IJV-specific knowledge that benefits both partners it stabilizes and sustains the IJV. Yet, joint...... learning in IJVs have rarely been examined in the context of IJVs in emerging markets. This paucity of studies concerning joint learning and knowledge creation in IJVs have been noted at a critical research gap in the literature....

    The Division of Lung Diseases of the NHLBI and the Cardiovascular Medical Education and Research Fund held a workshop to discuss how to leverage the anticipated scientific output from the recently launched "Redefining Pulmonary Hypertension through Pulmonary Vascular Disease Phenomics" (PVDOMICS) program to develop newer approaches to pulmonary vascular disease. PVDOMICS is a collaborative, protocol-driven network to analyze all patient populations with pulmonary hypertension to define novel pulmonary vascular disease (PVD) phenotypes. Stakeholders, including basic, translational, and clinical investigators; clinicians; patient advocacy organizations; regulatory agencies; and pharmaceutical industry experts, joined to discuss the application of precision medicine to PVD clinical trials. Recommendations were generated for discussion of research priorities in line with NHLBI Strategic Vision Goals that include: (1) A national effort, involving all the stakeholders, should seek to coordinate biosamples and biodata from all funded programs to a web-based repository so that information can be shared and correlated with other research projects. Example programs sponsored by NHLBI include PVDOMICS, Pulmonary Hypertension Breakthrough Initiative, the National Biological Sample and Data Repository for PAH, and the National Precision Medicine Initiative. (2) A task force to develop a master clinical trials protocol for PVD to apply precision medicine principles to future clinical trials. Specific features include: (a) adoption of smaller clinical trials that incorporate biomarker-guided enrichment strategies, using adaptive and innovative statistical designs; and (b) development of newer endpoints that reflect well-defined and clinically meaningful changes. (3) Development of updated and systematic variables in imaging, hemodynamic, cellular, genomic, and metabolic tests that will help precisely identify individual and shared features of PVD and serve as the basis of novel

    Many recuperators have components which react to corrosive gases and are used in applications where the donor fluid includes highly corrosive gases. These recuperators have suffered reduced life, increased service or maintenance, and resulted in increased cost. The present joint when used with recuperators increases the use of ceramic components which do not react to highly corrosive gases. Thus, the present joint used with the present recuperator increases the life, reduces the service and maintenance, and reduces the increased cost associated with corrosive action of components used to manufacture recuperators. The present joint is comprised of a first ceramic member, a second ceramic member, a mechanical locking device having a groove defined in one of the first ceramic member and the second ceramic member. The joint and the mechanical locking device is further comprised of a refractory material disposed in the groove and contacting the first ceramic member and the second ceramic member. The present joint mechanically provides a high strength load bearing joint having good thermal cycling characteristics, good resistance to a corrosive environment and good steady state strength at elevated temperatures.

    The six papers presented here as the proceedings of this second Joint CO/sub 2/ Research Team Meeting are examples of the research progress during the last two years. The first paper is documentation of the first numerical climate simulation model developed by the Institute of Atmospheric Physics in Beijing. Two papers from the National Oceanic and Atmospheric Administration's National Climatic Data Center at Asheville, North Carolina, demonstrate the work being done on the United States Historical Climatology Network data (the time series of temperature, precipitation, and sunshine) in the US. The fourth paper speaks of climate variability on a regional scale being much larger than that based on averages of global-wide data and therefore more difficult to predict. The China Precipitation Proxy Index covers a period of 510 years. This permits comparison of contemporary climate patterns (i.e., the last 100 years) with the period of the Little Ice Age when the mean temperature over China was 2/degree/ colder than present. The fifth paper is fascinating documentation of the effects of climate change upon the wild elephants whose habitat has shifted from as far north as Beijing, in historical times, to a currently small, sequestered section in the southwest corner of the country. The final paper demonstrates the pragmatic exchange of both data and technical assistance between the two countries.

    The diagnosis of temporomandibular joint (TMJ) disorders consists of clinical (Reaserch Diagnostic Criteria for Temporomandibular Disorders, RDC/TMD) and additional (computer tomography, CT or magnetic resonance imaging, and MRI) examinations. Due to the growing knowledge of pathologic changes within the TMJ, the researches become more aware of the difficulty in detection the early symptoms of disorders using conventional examination. Therefore, it is now expected that the collected samples of synovial fluid, serum, or urine samples could enable easier identification of inflammatory process course, and degenerative cartilage changes state.

    In the field of shielding nuclear energy plants certain problems of outstanding importance still require satisfactory solutions. Among these, particular importance is assumed by that of determining removal of sections for fission neutrons and that of calculating the propagation of neutrons and gamma rays by means of penetrations. On behalf of the Reactor Physics Department of Ispra, theoretical as well as practical research in this direction has been undertaken rather a long time ago. Two contracts have been concluded, the one with Padua University for measuring removal sections as a function of neutron energy, and the other with Sorin for measuring neutron distribution in cylindrical penetrations. At Ispra measuring activities are under way for determining gamma ray propagation by means of concrete penetrations. Theoretical studies for interpreting such measurements are also in progress. The first results obtained so far are being presented here.

    The objective of the research project 'The world of renewable energies: Powerado' was to improve communication aimed at conveying renewable energies to children. In order to achieve his aim, materials for different age groups and multipliers have been developed. These helped determining successful strategies for communicating renewable energies. There were several reasons for the need of such a project. It may be the case that renewable energies have been included into the syllabus of primary schools, but they still have no prominent role at schools. Additionally, the training of multipliers for renewable energies shows severe deficits. The project consisted of ten interconnected modules which explicitly are described. Overall, the powerado project was a huge success. 58,000 estimated multipliers, children, adolescents and persons generally being interested in renewable energies have been reached by the project and its modules. So the powerado project achieved its main objective improving communication of renewable energies.

    The density and pin count for Field Programmable Gate Arrays (FPGAs) has been increasing, and has exceeded current methods of solder joint inspection, making early detection of failures more problematic. These failures are a concern for both flight safety and maintenance in commercial aviation. Ridgetop Group, Inc. has developed a method for detecting solder joint failures in real time. The NASA Dryden Flight Research Center is developing a set of boards to test this method in ground environmental and accelerated testing as well as flight test on a Dryden F-15 or F-18 research aircraft. In addition to detecting intermittent and total solder joint failures, environmental data on the boards, such as temperature and vibration, will be collected and time-correlated to aircraft state data. This paper details the technical approach involved in the detection process, and describes the design process and products to date for Dryden s FPGA failure detection boards.

    Imagine being able to predict — with unprecedented accuracy and precision — the structure of the proton and neutron, and the forces between them, directly from the dynamics of quarks and gluons, and then using this information in calculations of the structure and reactions of atomic nuclei and of the properties of dense neutron stars (NSs). Also imagine discovering new and exotic states of matter, and new laws of nature, by being able to collect more experimental data than we dream possible today, analyzing it in real time to feed back into an experiment, and curating the data with full tracking capabilities and with fully distributed data mining capabilities. Making this vision a reality would improve basic scientific understanding, enabling us to precisely calculate, for example, the spectrum of gravity waves emitted during NS coalescence, and would have important societal applications in nuclear energy research, stockpile stewardship, and other areas. This review presents the components and characteristics of the exascale computing ecosystems necessary to realize this vision.

    We compiled the results of the source analysis obtained under the collaboration research. Recent construction scheme for source modeling adopted in Japan is described, and strong-motion prediction is performed assuming the scenario earthquakes occurring in the Ulsan fault system, Korea. Finally Qs values beneath the Korean inland crust are estimated using strong-motion records in Korea from the 2005 Off West Fukuoka earthquake (M7.0). Probabilistic seismic hazard for four NPP sites in Korea are evaluated, in which the site specific attenuation equations with Index SA developed for NPP sites are adopted. Furthermore, the uniform hazard spectra for the four NPP sites in Korea are obtained by conducting the PSHA by using the attenuation equations with the index of response spectra and seismic source model cases with maximum weights. The supporting tools for seismic response analysis, the evaluation tool for evaluating annual probability of failure, and system analysis program were developed for the collaboration. The tools were verified with theoretical results, the results written in the reference document of EQESRA, and so forth. The system analysis program was applied for the investigation of the effect of improving the seismic capacity of equipment. We evaluated the annual probability of failure of isolated and non-isolated EDG at Younggwang NPP site as the results of the collaboration. The input ground motion for generating the seismic fragility curve was determined based on the seismic hazard analysis. It was found that the annual probability of failure of isolated EDG is lower than that of non-isolated EDG.

    2016-01-01

    Despite multimodal treatment, long term outcome for patients with Ewing sarcoma is still poor. The second “European interdisciplinary Ewing sarcoma research summit” assembled a large group of scientific experts in the field to discuss their latest unpublished findings on the way to the identification of novel therapeutic targets and strategies. Ewing sarcoma is characterized by a quiet genome with presence of an EWSR1-ETS gene rearrangement as the only and defining genetic aberration. RNA-sequencing of recently described Ewing-like sarcomas with variant translocations identified them as biologically distinct diseases. Various presentations adressed mechanisms of EWS-ETS fusion protein activities with a focus on EWS-FLI1. Data were presented shedding light on the molecular underpinnings of genetic permissiveness to this disease uncovering interaction of EWS-FLI1 with recently discovered susceptibility loci. Epigenetic context as a consequence of the interaction between the oncoprotein, cell type, developmental stage, and tissue microenvironment emerged as dominant theme in the discussion of the molecular pathogenesis and inter- and intra-tumor heterogeneity of Ewing sarcoma, and the difficulty to generate animal models faithfully recapitulating the human disease. The problem of preclinical development of biologically targeted therapeutics was discussed and promising perspectives were offered from the study of novel in vitro models. Finally, it was concluded that in order to facilitate rapid pre-clinical and clinical development of novel therapies in Ewing sarcoma, the community needs a platform to maintain knowledge of unpublished results, systems and models used in drug testing and to continue the open dialogue initiated at the first two Ewing sarcoma summits.

  16. Temporomandibular joint disorders.

    Buescher, Jennifer J

    2007-11-15

    Temporomandibular joint disorders are common in adults; as many as one third of adults report having one or more symptoms, which include jaw or neck pain, headache, and clicking or grating within the joint. Most symptoms improve without treatment, but various noninvasive therapies may reduce pain for patients who have not experienced relief from self-care therapies. Physical therapy modalities (e.g., iontophoresis, phonophoresis), psychological therapies (e.g., cognitive behavior therapy), relaxation techniques, and complementary therapies (e.g., acupuncture, hypnosis) are all used for the treatment of temporomandibular joint disorders; however, no therapies have been shown to be uniformly superior for the treatment of pain or oral dysfunction. Noninvasive therapies should be attempted before pursuing invasive, permanent, or semi-permanent treatments that have the potential to cause irreparable harm. Dental occlusion therapy (e.g., oral splinting) is a common treatment for temporomandibular joint disorders, but a recent systematic review found insufficient evidence for or against its use. Some patients with intractable temporomandibular joint disorders develop chronic pain syndrome and may benefit from treatment, including antidepressants or cognitive behavior therapy.

    2011-09-01

    Full Text Available The temporo-mandibular joint (TMJ it’s a joint closely related to the skull base, the spine, and the jaws; all these anatomical structures must be taken in consideration when evaluating pain involving the tmj. In order to detect patients affected by pathology or dysfunctions of the tmj, physical examination is of great value in orienting the diagnosis. Inspection must consider the symmetry of the body, the dental status and the type of occlusion. Palpation is a way to assess contractiont involving the muscles of the masticatory system and of the neck. Auscultation, based on articular noise provides means to determine whether we are dealing with degeneration of the joint or a dislocation of the intrarticular disc. In order to confirm the diagnosis obtained with the clinical evaluation, it’s useful to perform imaging techniques as opt, tomography and TC of the tmj and electromyokineosiography – index of the mandibular functionality and of the muscles status. MRI and dynamic MRI are among the non invasive exams which give the greatest amount of information, regarding the disc position and the joint degeneration. Arthroscopy is an invasive technique that allows early diagnosis of degeneration and is helpful to reveal early inflammatory processes of the joint.

  18. Distal radioulnar joint injuries

    Directory of Open Access Journals (Sweden)

    Binu P Thomas

    2012-01-01

    Full Text Available Distal radioulnar joint is a trochoid joint relatively new in evolution. Along with proximal radioulnar joint , forearm bones and interosseous membrane, it allows pronosupination and load transmission across the wrist. Injuries around distal radioulnar joint are not uncommon, and are usually associated with distal radius fractures,fractures of the ulnar styloid and with the eponymous Galeazzi or Essex_Lopresti fractures. The injury can be purely involving the soft tissue especially the triangular fibrocartilage or the radioulnar ligaments.The patients usually present with ulnar sided wrist pain, features of instability, or restriction of rotation. Difficulty in carrying loads in the hand is a major constraint for these patients. Thorough clinical examination to localize point of tenderness and appropriate provocative tests help in diagnosis. Radiology and MRI are extremely useful, while arthroscopy is the gold standard for evaluation. The treatment protocols are continuously evolving and range from conservative, arthroscopic to open surgical methods. Isolated dislocation are uncommon. Basal fractures of the ulnar styloid tend to make the joint unstable and may require operative intervention. Chronic instability requires reconstruction of the stabilizing ligaments to avoid onset of arthritis. Prosthetic replacement in arthritis is gaining acceptance in the management of arthritis.

    OBJECTIVES - To determine the combined effects 1) of stress-field aspect ratio and velocity and compressive strain and 2) joint load, on temporomandibular joint (TMJ) disc mechanics. SETTING AND SAMPLE POPULATION - Fifty-two subjects (30 female; 22 male) participated in the TMJ load experiments. MATERIAL AND METHODS - In the absence of human tissue, pig TMJ discs were used to determine the effects of variables 1) on surface plowing forces, and to build a biphasic finite element model (bFEM) to test the effect of human joint loads and 2) on tissue stresses. In the laboratory, discs received a 7.6 N static load via an acrylic indenter before cyclic movement. Data were recorded and analysed using anova. To determine human joint loads, Research Diagnostic Criteria calibrated investigators classified subjects based on signs of disc displacement (DD) and pain (+DD/+pain, n = 18; +DD/-pain, n = 17; -DD/-pain, n = 17). Three-dimensional geometries were produced for each subject and used in a computer model to calculate joint loads. RESULTS - The combined effects of compressive strain, and aspect ratio and velocity of stress-field translation correlated with plowing forces (R(2) = 0.85). +DD/-pain subjects produced 60% higher joint loads (ANOVA, p dynamic variables of the stress-field and subject-dependent joint load significantly affect disc mechanics.

    comparison with models will provide important results over the next year or two. Many codes were improved in significant ways in order to model data under the challenging conditions of the pedestal. In addition, new and strengthened collaborations were established between experiment, modeling and theory, and these efforts include providing mechanisms for sharing experimental data. All of these efforts will continue to provide major benefits to future pedestal studies. Much of the experimental and modeling work performed to support this milestone is reported in detail in the research contributions to this report. Here, a summary of results from the various contributions, as they pertain to several proposed pedestal physics processes, is discussed here. Emphasis is placed on mechanisms for which there are results from one or more machines or one or more models. Work from preceding quarterly reports is used for some of this summary. At the end of this summary, a brief summary of implications for ITER and implications for future work will be presented.

    机械系统由多个零部件组成,零件与零件之间是边界非线性的接触问题。在求解了接触问题之后,才能求解机械系统。机床设备对精度的要求非常高,在求解接触问题时必须要考虑零件表面不完整性和工况等综合因素对整机性能的影响。由于接触表面层表现出了与零件本体材料显著不同的力学特性,使得接触问题变得更加复杂。因此,在研究机械系统的性能时,需要将接触问题和接触表面层的非线性特性耦合起来求解。重点研究了耦合求解算法,也就是把结合面的非线性接触刚度作为罚参数引入罚函数有限元算法中来处理接触问题。最后通过实验进行了多次检测,验证了耦合分析结果与实验结果基本一致,验证了机械系统有限元耦合分析算法的有效性。%A machine system is composed of many parts.The no linear boundary contact prob-lems exist in a machine system.After solving those contact problems,the machine system’s character-istics can be obtained.When solving those contact problems,it must consider the influence of the sur-face incomplete character on the global characteris-tic of some machine tools which demand very high precision.The contact problems become much more complicated,because the contact surface layers dis-play a different mechanical behavior from the part body.So it needs to couple the contact problem with the no linear characteristic parameters on j oint surface when solving the global characteristic of a machine system.This paper focuses on the re-search of coupling algorithm.And the no linear contact stiffness was introduced into the penalty function method as a penalty parameter to solve the contact problem.By lots of experiments,it proved that the result of the coupling analysis pro-gram is approach to the experiment ’s result at last,and it proved that the coupling analysis meth-od is effective.

    Purpose This retrospective original research was designed to illustrate the general outcome after radiofrequency (RF) neurotomy of lumbar medial branch (MB) and posterior ramus of the sacroiliac joint of 160 patients with chronic low back pain (LBP) 1, 6, and 12 months after treatment. Methods Visual Analog Scale (VAS) 0–10 pain scores, quality of life, body mass index (BMI), medication usage, and frequency of physical exercise/sports participation (none, 1–3×/week, more) were collected before the procedure, at 1 month post procedure (n=160), and again at 6 (n=73) and 12 months (n=89) post procedure. Results A VAS decrease of 4 points on a 10-point scale (from 8 to 4) in the overall group was seen after 6 months and of 4.5 after 12 months. Lower medication usage was reported, with opioids decreased by 40% and nonsteroidal anti-inflammatory drugs (NSAIDs) by 60%. Decreased pain lasted for 12 months. Significantly better outcomes were reported by patients with BMIs 30 are less likely to report decreased pain. The better long-term pain relief in the sports participating group is a motivation for the authors to keep the patients in motion. PMID:28144161

    Full Text Available Studies of a welded joint were described. The joint was made as a result of the reconstruction of a truss and one of the possible means to make a repair. The studies were of a simulation character and were targeted at the detection of welding defects and imperfections thatshould be eliminated in a real structure. A model was designed and on this model the tests and examinations were carried out. The modelwas made under the same conditions as the conditions adopted for repair. It corresponded to the real object in shape and dimensions, and in the proposed technique of welding and welding parameters. The model was composed of five plates joined together with twelve beads.The destructive and non-destructive tests were carried out; the whole structure and the respective welds were also examined visually. Thedefects and imperfections in welds were detected by surface methods of inspection, penetration tests and magnetic particle flaw detection.The model of the welded joint was prepared by destructive methods, a technique that would never be permitted in the case of a realstructure. For the investigations it was necessary to cut out the specimens from the welded joint in direction transverse to the weld run. The specimens were subjected to metallographic examinations and hardness measurements. Additionally, the joint cross-section was examined by destructive testing methods to enable precise determination of the internal defects and imperfections. The surface methods were applied again, this time to determine the severity of welding defects. The analysis has proved that, fabricated under proper conditions and with parameters of the welding process duly observed, the welded joint has good properties and repairs of this type are possible in practice.

    A joint is described for connecting a pair of beams to pivot them between positions in alignment or beside one another, which is of light weight and which operates in a controlled manner. The joint includes a pair of fittings and at least one center link having opposite ends pivotally connected to opposite fittings and having axes that pass through centerplates of the fittings. A control link having opposite ends pivotally connected to the different fittings controls their relative orientations, and a toggle assemly holds the fittings in the deployed configuration wherein they are aligned. The fittings have stops that lie on one side of the centerplane opposite the toggle assembly.

    The load capacity of bonded joints can be increased if transverse pressure is applied at the interface. The transverse pressure is assumed to introduce a Coulomb-friction contribution to the cohesive law for the interface. Response and load capacity for a bonded single-lap joint was derived using...... non-linear fracture mechanics. The results indicated a good correlation between theory and tests. Furthermore, the model is suggested as theoretical base for determining load capacity of bonded anchorages with transverse pressure, in externally reinforced concrete structures....

    Multiple types of programs are needed to support the STEM workforce pipeline from pre-college through graduate school and beyond. Short-term, intensive programs provide opportunities to participate in authentic scientific research for students who may not be sure of their interest in science and for teachers who may be unable to devote an entire summer to a research experience. The iUTAH (innovative Urban Transitions and Aridregion Hydro-Systainability) Summer Research Institute utilizes an innovative approach for a 5-day program that engages high school and undergraduate students as well as middle and high school teachers in conducting research projects led by graduate students and faculty members. Each Institute involves 3-4 half to full-day research projects. Participants collect (usually in the field) and analyze data for use in on-going research or that is related to a current research project. The participants work in groups with the graduate students to create a poster about each research project. They present their posters on the last day of the Institute at the state-wide meeting of all researchers and involved in this EPSCoR-funded program. In addition to introducing participants to research, one of the Institute's goals is to provide opportunities for meaningful near-peer interactions with students along the STEM pipeline from high school to undergraduate to graduate school. On the end-of-Institute evaluations, almost all students have reported that their discussions with other participants and with graduate students and faculty were a "Highly effective" or "Effective" part of the Institute. In response to a question about how the Institute will impact their course choices or their plans to pursue a career in science, many high school and undergraduate students have noted that they plan to take more science courses. Each year several undergraduates who were previously unsure about a career in science have indicated that they now intend to pursue a

    China is surveyed for promotion of joint implementation, which is one of the flexibility measures in the Kyoto Protocol, the Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change. The project aims to collect methane for global warming suppression and to use it as town gas and for power generation as well. The survey covers the 2 coalfields of Yangquan and Panjiang. The Yangquan coalfield is the largest anthracite yielding base in China, with 6 mines in operation. Power generation centering on a 100MW plant is discussed, and generation fired by a mixture of debris out of the coal preparation facility and gas is compared with another fired by town gas, on the assumption that 130-million m{sup 3} is available under the current circumstances. In the case of the Panjiang coalfield, which is expected to develop into a large coal base in the southern part of China, power generation centering on a 50MW plant fired by a mixture of debris and gas is discussed, on the assumption that 63-million m{sup 3} is collectable from the existing 5 mines. Use of town gas is also studied. When Japan's coalbed methane collection technology is applied, the gas drainage rate will be elevated to 40-35% or higher. It is desired that the use of gas drainage will be further diffused for the prevention of disasters of coal mine gas explosion. It is hoped that the use of environmentally friendly energies will be enhanced. (NEDO)

    The Third International Workshop on Jointed Structures was held from August 16th to 17th, 2012, in Chicago Illinois, following the ASME 2012 International Design Engineering Technical Conferences and Computers and Information in Engineering Conference. Thirty two researchers from both the United States and international locations convened to discuss the recent progress of mechanical joints related research and associated efforts in addition to developing a roadmap for the challenges to be addressed over the next five to ten years. These proceedings from the workshop include the minutes of the discussions and follow up from the 2009 workshop [1], presentations, and outcomes of the workshop. Specifically, twelve challenges were formulated from the discussions at the workshop, which focus on developing a better understanding of uncertainty and variability in jointed structures, incorporating high fidelity models of joints in simulations that are tractable/efficient, motivating a new generation of researchers and funding agents as to the importance of joint mechanics research, and developing new insights into the physical phenomena that give rise to energy dissipation in jointed structures. The ultimate goal of these research efforts is to develop a predictive model of joint mechanics.

    2016-03-01

    Joining of materials in structural design has always been a challenge for engineers. Bolting and riveting has been used for many years, until the emergence of fusion welding which revolutionised construction in areas such as shipbuilding, automotive, infrastructure and consumer goods. Extensive research in the past 50 years has resulted in better understanding of the process and minimised the occurrence of failures associated with fusion welding such as, residual stress cracking, stress corrosion and corrosion fatigue cracking, localised reduction in mechanical properties due to microstructural changes (heat affected zone) etc. Bonding has been a technique that has been proposed as an alternative because it eliminates several of the problems associated with fusion welding. But, despite some applications it has not seen wide use. There is however a renewed interest in adhesively bonded joints, as designers look for ever more efficient structures which inevitably leads to the use and consequently joining of combinations of lightweight materials, often with fundamentally different mechanical and physical properties. This chapter provides a review of adhesively bonded joints and reports on improvements to bonded joint strength through the introduction of carbon nanotubes at the bond interface. Results from various workers in the field are reported as well as the findings of the authors in this area of research. It is obvious that there are several challenges that need to be addressed to further enhance the strength of bonded joints and worldwide research is currently underway to address those shortcomings and build confidence in the implementation of these new techniques.

  5. Biofluid lubrication for artificial joints

    Science.gov (United States)

    Pendleton, Alice Mae

    This research investigated biofluid lubrication related to artificial joints using tribological and rheological approaches. Biofluids studied here represent two categories of fluids, base fluids and nanostructured biofluids. Base fluids were studied through comparison of synthetic fluids (simulated body fluid and hyaluronic acid) as well as natural biofluids (from dogs, horses, and humans) in terms of viscosity and fluid shear stress. The nano-structured biofluids were formed using molecules having well-defined shapes. Understanding nano-structured biofluids leads to new ways of design and synthesis of biofluids that are beneficial for artificial joint performance. Experimental approaches were utilized in the present research. This includes basic analysis of biofluids' property, such as viscosity, fluid shear stress, and shear rate using rheological experiments. Tribological investigation and surface characterization were conducted in order to understand effects of molecular and nanostructures on fluid lubrication. Workpiece surface structure and wear mechanisms were investigated using a scanning electron microscope and a transmission electron microscope. The surface topography was examined using a profilometer. The results demonstrated that with the adding of solid additives, such as crown ether or fullerene acted as rough as the other solids in the 3-body wear systems. In addition, the fullerene supplied low friction and low wear, which designates the lubrication purpose of this particular particle system. This dissertation is constructed of six chapters. The first chapter is an introduction to body fluids, as mentioned earlier. After Chapter II, it examines the motivation and approach of the present research, Chapter III discusses the experimental approaches, including materials, experimental setup, and conditions. In Chapter IV, lubrication properties of various fluids are discussed. The tribological properties and performance nanostructured biofluids are

    The problem of understanding and modeling the complicated physics underlying the action and response of the interfaces in typical structures under dynamic loading conditions has occupied researchers for many decades. This handbook presents an integrated approach to the goal of dynamic modeling of typical jointed structures, beginning with a mathematical assessment of experimental or simulation data, development of constitutive models to account for load histories to deformation, establishment of kinematic models coupling to the continuum models, and application of finite element analysis leading to dynamic structural simulation. In addition, formulations are discussed to mitigate the very short simulation time steps that appear to be required in numerical simulation for problems such as this. This handbook satisfies the commitment to DOE that Sandia will develop the technical content and write a Joints Handbook. The content will include: (1) Methods for characterizing the nonlinear stiffness and energy dissipation for typical joints used in mechanical systems and components. (2) The methodology will include practical guidance on experiments, and reduced order models that can be used to characterize joint behavior. (3) Examples for typical bolted and screw joints will be provided.

    The Joint Simon Effect (JSE) is a spatial stimulus-response compatibility effect that appears when two participants complete complementary components of a standard Simon task. The effect is considered as a valid index of the degree of self-other integration. Two main factors can influence the effect:social and nonsocial factors. Researchers explain JSE through the social facilitation theory, the co-representation account, the spatial response coding theory and the referential coding account. Future work on JSE should further explore the factors that influence it and the underlying brain mechanism, and further investigate its theoretical underpinnings.%联合 Simon 效应是一种空间刺激–反应相容性效应,它出现在当两个参与者完成 Simon 任务的互补成分时。该效应被认为是反映自我–他人整合程度的一个有效指标。影响此现象的因素主要包括社会和非社会因素。社会促进理论、共同表征理论、空间反应编码理论和参照编码理论对该效应作出了解释。未来关于联合Simon 效应的研究需深入探讨其影响因素以及脑机制,并进一步完善理论解释。

    作为一种有效的合作研发创新组织形式,尽管中小企业研究联合体具有很强的活力和创新潜力,但在实践中会由于多种原因致使其生命力不强、寿命较短或效率不高,不能发挥理论意义上强大的创新实力.中小企业研究联合体要想发挥竞争优势,必须构建稳定的信任机制.中小企业RJVs信任机制稳定性既取决于内部信任机制,又受外部信任机制的影响;内部信任机制是关键,外部信任机制是有力补充;二者相互作用,才能实现中小企业RJVs信任机制的稳定运行.%RJVs of SMEs, as an effective cooperation innovation organization form, has the very strong vitality and innovation potential. But It is short life or its efficiency is not high because of many reasons in practice, so it cannot develop theoretically powerful innovation strength. This paper analyzes the meaning, characteristics and advantages of the stability in trust mechanism of research joint ventures of the small and medium-sized enterprise, and discusses the internal and external factors. At last, the paper concludes with stable model study in trust mechanism. The stable trust mechanism of SMEs' RJVs is decided by the internal trust mechanism, also receives the exterior trust mechanism the influence. The internal trust mechanism is a key, and the exterior trust mechanism is the powerful supplement. The two interaction can realize the trust mechanism of SMEs' RJVs steady operation.

    Prevalence of disability among leprosy patients and effectiveness of standard predonisolone treatment for leprosy reaction at field level in some place of Myanmar are shown in this paper as results of joint leprosy research collaboration. WHO disability grading was measured for all newly registered leprosy patients through 2007 in 5 selected townships of Ayeyarwaddy Division, with the results of G0 = 66.3%, GI = 18.9%, GII = 14.7% (N = 95). The cross-sectional disability survey at selected 9 townships in Mandalay, Sagaing and Magway Division for all registered patients who had completed WHO/MDT done by JICA project in 2003/4 showed G0 = 62.5%, GI = 2.4%, GII = 35.1% (N = 10,528). From these two data, it is supposed that considerable number of patients with G1 at registered time developed worsening of disability from G1 to G2. Proportion of G0 also reduced a little bit in patients who completed WHO/MDT. Early detection and proper treatment of leprosy reaction are one of the main issues of prevention of disability. Effectiveness of leprosy reaction services were evaluated at Mandalay Special Skin Clinic, where WHO fixed regimen of prednisolone were given as routine service. 100 cases were evaluated who developed leprosy reactions from 1st December 2007 to 31st December 2008 and identified severe reaction who needed oral prednisolone treatment. Evaluation criteria of "effective" was defined as "no more signs and symptoms of reactions were present after treatment. And "less effective" was defined as "more than one of signs and symptoms were still remained after treatment". Over all "effective" was 36 (36%) and "less effective" was 64 (64%). It was also found that rates of improvement of nerve functions, either in sensory or in motor, were little after the standard treatment.

    2017-03-01

    The development of animal models for research has been very diffused. Osteoarthritis is a joint degenerative pathology that induces cartilage erosion, chondrocyte proliferation and osteophyte formation. The aim of this paper is to present a technical procedure to perform the injection of monosodium iodine acetate in the temporomandibular joints of rats to generate osteoarthritis and to contribute to future research analysis related to pathology progression and proper treatment performance. The use of rat models may be a complex process because of their size, but they can be compared to the human temporomandibular joint due to the similar characteristics and the possibility of performing diagnosis and treatment protocols in order to detect this pathology.

    Joint Implementation (JI) appears to have been born with Applied Energy Services Guatemala project in 1988. That project, to plant 52 million trees, protect existing forests from cutting and fire, and enhance rural development, is being implemented by CARE Guatemala to offset 120 per cent of the emissions of a small coal burning power plant that has been built in Connecticut. Since that time, several utilities and governments have initiated additional projects. Not all of these necessarily consist of tree planting in other countries, but may consist of energy efficiency or energy conservation programs designed to reduce carbon emissions by at least as much as the additional releases from a new facility. All JI projects share the characteristic of linking the release of greenhouse gases in an industrial country with an offset that reduces or absorbs a comparable amount in another country. The emitter in the industrial country is willing to pay for the reduction elsewhere because costs are less than they would be at home.

    2017-06-14

    The miniaturization of machines towards the micron and nanoscale requires the development of joint-like elements that enable and constrain motion. We present a facile method to create colloidal joints, that is, anisotropic colloidal particles functionalized with surface mobile DNA linkers that control the motion range of bonded particles. We demonstrate quantitatively that we can control the flexibility of these colloidal joints by tuning the DNA linker concentration in the bond area. We show that the shape of the colloidal joint controls the range of motion of bonded particles through a maximisation of the bond area. Using spheres, cubes, and dumbbells, we experimentally realize spherical joints, planar sliders, and hinges, respectively. Finally we demonstrate the potential of the colloidal joints for programmable bottom-up self-assembly by creating flexible colloidal molecules and colloidal polymers. The reconfigurability and motion constraint offered by our colloidal joints make them promising building blocks for the development of switchable materials and nanorobots.

  2. Laundry joint venture.

    1984-12-01

    Many hospitals are concerned about the loss of control which is associated with contracting for linen service. On the the hand, many laundries do not have the resources or experience to serve hospitals in a comprehensive and trouble-free manner. In many communities a joint venture, such as the one described here, can successfully combine the interests of the hospital and laundry communities without causing the hospitals to lose control of the service and without requiring the laundry operator to have detailed knowledge of hospital operations. As more hospitals opt for contract service, and if this service is to be provided at the lowest total cost, the hospitals and the laundries must come to grips with the problems surrounding the laundry-hospital interface. A joint venture, such as that described here, is one way to accomplish this.

    Full Text Available Osteoarthritis, a degenerative joint disease, is the most commonrheumatic disorder mainly in a geriatric population. Manifestationsare pain, stiffness and functional loss in the affected joint.According to etiology it is classifi ed as primary (or idiopathicand secondary. Some risk factors for disease development aregenetics, race, age, sex, obesity, occupational activities andarticular biomechanics. Pathogenesis is the same for any cause orlocalization, being catabolic alterations, with synthesis, inhibitionand reparing intent of the cartilage matrix. Metalloproteinases andcytokines (IL-1,IL-6,TNF-α actions promote infl ammatory reactionand cartilage degradation. Pain, the most important symptom,does not correlate with radiologic fi ndings. Peripheral osteoarthritisoccurs predominantly in the knee, hip and hand. Diagnosis is basedon clinical features, laboratorial tests and radiological changes.Rheumatological associations’ guidelines for treatment includenon-pharmacologic (education, physiotherapy, assistive devices,and pharmacologic (analgesics, anti-infl ammatory drugs therapyand surgery. Arthroplasty seems to work better than medicines, butshould be used if other treatments have failed.

    MRI of the temporomandibular joint (TMJ) requires 1.5 T. The radiologist must be familiar with the anatomy and pathology of the TMJ. This review gives a description of MRI protocols for the TMJ, and MRI anatomy and pathology of the TMJ (open and closed mouth) by means of MR images and drawings. Diagnosing of the TMJ related diseases depends on standardized clinical and MR examinations. Therefore close interdisciplinary cooperation between dentist and radiologist is necessary.

    Subtalar joint arthrodesis is a commonly performed procedure for the correction of hindfoot deformity and/or the relief of pain related to osteoarthritis. The purpose of the present study was to provide preoperative and intraoperative objective radiographic parameters to improve the accuracy and long-term success of realignment arthrodesis of the subtalar joint. We retrospectively reviewed the data from 16 patients, 11 male (57.9%) and 8 female (42.1%) feet, who had undergone realignment subtalar joint arthrodesis. A total of 19 fusions were performed in 9 (47.4%) right and 10 (52.6%) left feet, with a mean follow-up period of 2 (range 1 to 4.8) years. The mean age at surgery was 54.5 (range 14 to 77) years. Statistically significant improvement in radiographic alignment was found in the anteroposterior talo-first metatarsal angle (p = .002), lateral talo-first metatarsal angle (p < .001), tibial-calcaneal angle (p < .001), and tibial-calcaneal distance (p < .001). A positive correlation was observed between the tibial-calcaneal angle and tibial-calcaneal distance (r = 0.825, p < .001). The statistically significant improvement in tibial-calcaneal alignment, in both angulation and distance, support our conclusions that proper realignment of the calcaneus to vertical and central under the tibia will lead to short-term success and, likely, long-term success of subtalar joint arthrodesis.

    Study Design  An international, multicenter cross-sectional image-based study performed in 33 institutions in the Asia Pacific region. Objective  The study addressed the role of facet joint angulation and tropism in relation to L4–L5 degenerative spondylolisthesis (DS). Methods  The study included 349 patients (63% females; mean age: 61.8 years) with single-level DS; 82 had no L4–L5 DS (group A) and 267 had L4–L5 DS (group B). Axial computed tomography and magnetic resonance imaging were utilized to assess facet joint angulations and tropism (i.e., asymmetry between facet joint angulations) between groups. Results  There was a statistically significant difference between group A (left mean: 46.1 degrees; right mean: 48.2 degrees) and group B (left mean: 55.4 degrees; right mean: 57.5 degrees) in relation to bilateral L4–L5 facet joint angulations (p < 0.001). The mean bilateral angulation difference was 7.4 and 9.6 degrees in groups A and B, respectively (p = 0.025). A critical value of 58 degrees or greater significantly increased the likelihood of DS if unilateral (adjusted OR: 2.5; 95% CI: 1.2 to 5.5; p = 0.021) or bilateral facets (adjusted OR: 5.9; 95% CI: 2.7 to 13.2; p < 0.001) were involved. Facet joint tropism was found to be relevant between 16 and 24 degrees angulation difference (adjusted OR: 5.6; 95% CI: 1.2 to 26.1; p = 0.027). Conclusions  In one of the largest studies assessing facet joint orientation in patients with DS, greater sagittal facet joint angulation was associated with L4-L5 DS, with a critical value of 58 degrees or greater increasing the likelihood of the condition for unilateral and bilateral facet joint involvement. Specific facet joint tropism categories were noted to be associated with DS. PMID:27433424

    A laboratory characterization of the Apache Leap tuff joints under cyclic pseudostatic and dynamic loads has been undertaken to obtain a better understanding of dynamic joint shear behavior and to generate a complete data set that can be used for validation of existing rock-joint models. Study has indicated that available methods for determining joint roughness coefficient (JRC) significantly underestimate the roughness coefficient of the Apache Leap tuff joints, that will lead to an underestimation of the joint shear strength. The results of the direct shear tests have indicated that both under cyclic pseudostatic and dynamic loadings the joint resistance upon reverse shearing is smaller than that of forward shearing and the joint dilation resulting from forward shearing recovers during reverse shearing. Within the range of variation of shearing velocity used in these tests, the shearing velocity effect on rock-joint behavior seems to be minor, and no noticeable effect on the peak joint shear strength and the joint shear strength for the reverse shearing is observed.

    The thermomechanical fatigue failure of solder joints is increasingly becoming an important reliability issue for electronic packages. The purpose of this Laboratory Directed Research and Development (LDRD) project was to develop computational tools for simulating the behavior of solder joints under strain and temperature cycling, taking into account the microstructural heterogeneities that exist in as-solidified near eutectic Sn-Pb joints, as well as subsequent microstructural evolution. The authors present two computational constitutive models, a two-phase model and a single-phase model, that were developed to predict the behavior of near eutectic Sn-Pb solder joints under fatigue conditions. Unique metallurgical tests provide the fundamental input for the constitutive relations. The two-phase model mathematically predicts the heterogeneous coarsening behavior of near eutectic Sn-Pb solder. The finite element simulations with this model agree qualitatively with experimental thermomechanical fatigue tests. The simulations show that the presence of an initial heterogeneity in the solder microstructure could significantly degrade the fatigue lifetime. The single-phase model was developed to predict solder joint behavior using materials data for constitutive relation constants that could be determined through straightforward metallurgical experiments. Special thermomechanical fatigue tests were developed to give fundamental materials input to the models, and an in situ SEM thermomechanical fatigue test system was developed to characterize microstructural evolution and the mechanical behavior of solder joints during the test. A shear/torsion test sample was developed to impose strain in two different orientations. Materials constants were derived from these tests. The simulation results from the two-phase model showed good fit to the experimental test results.

  16. Joint attention, social cognition and recognition memory in adults

    Full Text Available The early emerging capacity for Joint Attention, or socially coordinated visual attention, is thought to be integral to the development of social-cognition in childhood. Recent studies have also begun to suggest that joint attention affects adult cognition as well, but methodological limitations hamper research on this topic. To address this issue we developed a novel virtual reality (VR paradigm that integrates eye-tracking and virtual avatar technology to measure two types of joint attention in adults, Initiating Joint Attention (IJA and Responding to Joint Attention (RJA. Distinguishing these types of joint attention in research is important because they are thought to reflect unique, as well as common constellations of processes involved in human social-cognition and social learning. We tested the validity of the differentiation of IJA and RJA in our paradigm in two studies of picture recognition memory in undergraduate students. Study 1 indicated that young adults correctly identified more pictures they had previously viewed in an IJA condition (67% than in a RJA (58% condition, η2 = .57. Study 2 controlled for IJA and RJA stimulus viewing time differences, and replicated the findings of Study 1. The implications of these results for the validity of the paradigm and research on the affects of joint attention on adult social-cognition are discussed.

  17. Using joint interviews in a narrative-based study on illness experiences.

    Researchers are increasingly recognizing the usefulness of using joint interviews in research on illness experiences. However, there is limited discussion of joint interviews as a data collection method and of the factors that influence the choice to conduct individual or joint interviews. Although there are several advantages and disadvantages of both methods, the reasons that underpin the choice to use joint interviews are often not discussed in detail in the literature. Drawing from a narrative-based study on the experiences of living with motor neuron disease, we present joint interviews as a method sensitive both to the shared experience of illness and to the multiple perspectives around illness. Using interview excerpts, we discuss how through the use of joint interviews researchers can explore the intersubjective and heteroglossic nature of illness experiences. We argue that using joint interviews can offer valuable information about how couples coconstruct meaning and share experiences.

  18. Does generalized joint hypermobility predict joint injury in sport? A review.

    LENUS (Irish Health Repository)

    Donaldson, Peter R

    2012-02-01

    OBJECTIVE: To determine whether persons with generalized joint hypermobility have an increased risk of lower limb joint injury during sport. DATA SOURCES: PubMed, CINAHL, EMBASE, and SportDiscus were searched through February 2009, without language restrictions, using terms related to risk; hip, ankle, and knee injuries; and joint instability. Reference lists of included studies and relevant reviews were searched by hand. STUDY SELECTION: Selection criteria were peer-reviewed studies with a prospective design that used an objective scale to measure generalized joint hypermobility; the participants were engaged in sport activity, and the injury data were quantitative and based on diagnosis by a health professional, were self-reported, or resulted in time lost to athletic participation. The studies were screened by 1 researcher and checked by a second. Study methods were independently assessed by 2 investigators using the 6-point scale for prognostic studies developed by Pengel. Disagreements were resolved through discussion. Of 4841 studies identified, 18 met inclusion criteria. Of these, 8 were included in random-effects meta-analyses. DATA EXTRACTION: The data extracted by 2 reviewers included participant and sport characteristics and details of joint hypermobility and injury measurements. More detailed data for 4 investigations were obtained from the study authors. Where possible, hypermobility was defined as >\\/=4 of 9 points on the British Society of Rheumatology Scale (BSRS). MAIN RESULTS: Lower limb joint injuries (3 studies, 1047 participants) occurred in 14% of participants. Using the BSRS of joint hypermobility, any lower limb injury was not associated with hypermobility [odds ratio (OR), 1.43; 95% confidence interval (CI), 0.56-3.67]. Using the original authors\\' definitions, hypermobility was associated with risk of knee joint injuries (OR, 2.62; 95% CI, 1.04-6.58) in 5 studies. In 4 studies in which the BSRS could be used (1167 participants; incidence

  20. Anatomical and physiological considerations regarding the temporomandibular joint.

    Boering, G

    1979-12-01

    The structure and function of the human temporomandibular joint has concerned several investigators but still fundamental questions exist and require further examination. A profound knowledge of the normal anatomy and histology of the temporomandibular joint is necessary to understand its function and functional disturbances. It is also necessary for a good understanding of clinical findings and the interpretation of radiographs. In this paper a clinically orientated description has been given of the anatomy and histology of the mandibular head, the articular fossa and eminence, the articular disc, the capsule and ligaments, the synovial membrane, the innervation of the joint and the normal relationship between the different components. About the physiology of the temporomandibular joint many controversial theories exist. A lot of research has still to be done, especially in the field of the co-ordination of the function of both joints, the muscles and the dentition.

    Temporomandibular joint (TMJ) disorders are a common disease and may be responsible for major functional and painful repercussions. Treatment is not consensual. The literature highlights the role of conservative treatments (physiotherapy, analgesics, splints) in a first attempt. Minimally invasive surgical techniques (arthroscopy, arthrocentesis) have developed rapidly in recent decades. They have proven effective and reliable, especially in patients suffering from irreducible or reducible anterior disc dislocation or presenting with arthopathies. The goal of our work was to make an update about disk surgery. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Temporomandibular joint (TMJ) dislocation can be classified into four groups (anterior, posterior, lateral, and superior) depending on the direction of displacement and the location of the condylar head. All the groups are rare except for anterior dislocation. 'Inverse' TMJ dislocation is a bilateral anterior and superior dislocation with impaction of the mandible over the maxilla; to the authors' knowledge only two cases have previously been reported in the literature. Inverse TMJ dislocation has unique clinical and radiographic findings, which are described for this case. Copyright © 2011 International Association of Oral and Maxillofacial Surgeons.

Hospitals and physician groups also have made them the vehicles for coming together. Surgery centers allow hospitals and physicians to align incentives and share benefits. It is one of the few types of health care businesses physicians can own without anti-fraud and abuse violation. As a result, many surgery center ventures are now jointly owned by hospitals and physician groups. This article outlines common structures that have been used successfully to allow both to own and govern surgery centers.

    正颌术术后的复发往往与颞下颌关节(TMJ)结构和位置异常有关,包括髁突移位、进行性髁突吸收和关节盘移位等。正颌外科作为一种创伤性的手术,对TMJ的结构和位置能产生一定的影响。由于牙颌面畸形患者往往术前即有TMJ的疾病,因此正颌手术本身对TMJ的影响是否导致了复发和产生颞下颌关节紊乱病(TMD)需要多项研究探索。有一些学者提出,正颌手术同期行关节盘复位术可提高手术效果稳定性。对预防由于TMJ结构和位置异常引起的复发或TMD,目前临床尚无特定方法。鉴于此,本文将在正颌外科对TMJ结构的影响,与TMD的关系,以及预防术后复发和TMD的方法等三个方面进行综述。%Relapse after orthognathic surgery always results from condylar or/and articular disk displacement and progressive condylar absorption . Orthognathic surgery which is a traumatic method to correct the dentofacial deformity, changes the structure of temporomandibular joint simultaneously. While the patients suffered from dentofacial deformity also have a high prevalence of signs and symptoms of TMD. Further researches are needed to confirm whether orthognathic surgery could lead to reoccurrence or occurrence of TMD or not. Some studies shown that orthognathic surgery was a stable procedure for patients undergoing simultaneous TMJ disc repositioning. There is no specific strategy could be applied to prevent the deformity relapse and TMD after orthognathic surgery . Literatures, published in this 5 years, on the relationships among TMD, dentofacial deformities and orthognathic surgery, were reviewed.

    Full Text Available Abstract Background Pain referral patterns of asymptomatic costotransverse joints have not been established. The objective of this study was to determine the pain referral patterns of asymptomatic costotransverse joints via provocative intra-articular injection. Methods Eight asymptomatic male volunteers received a combined total of 21 intra-articular costotransverse joint injections. Fluoroscopic imaging was used to identify and isolate each costotransverse joint and guide placement of a 25 gauge, 2.5 inch spinal needle into the costotransverse joint. Following contrast medium injection, the quality, intensity, and distribution of the resultant pain produced were recorded. Results Of the 21 costotransverse joint injections, 16 (76% were classified as being intra-articular via arthrograms taken at the time of injection, and 14 of these injections produced a pain sensation distinctly different from that of needle placement. Average pain produced was 3.3/10 on a 0–10 verbal pain scale. Pain was described generally as a deep, dull ache, and pressure sensation. Pain patterns were located superficial to the injected joint, with only the right T2 injections showing referred pain 2 segments cranially and caudally. No chest wall, upper extremity or pseudovisceral pains were reported. Conclusion This study provides preliminary data of the pain referral patterns of costotransverse joints. Further research is needed to compare these findings with those elicited from symptomatic subjects.

    Current codes recommend large amounts of shear reinforcement for reinforced concrete beam-column joints causing significant congestion. This research aims at investigating experimentally and numerically the efficiency of using studs with a head at each end in lieu of conventional closed hoops in reinforced concrete beam-column joints. The proposed reinforcement reduces congestion and ensures easier assembly of the reinforcing cage, saving labour cost and enhancing performance of the joint. Based on this research, a recommended arrangement and detailing of headed studs and their design for exterior beam-column joint are presented. The experimental investigation consisted of testing ten full-scale beam-column joint specimens under quasi-static cyclic loading. The specimens represented an exterior beam-column joint subassembly isolated at the points of contra-flexure from a typical multi-storey, multi-bay reinforced concrete frame. A test setup was developed to simulate the lateral inter-storey drift. The test parameters included: the type, arrangement and amount of shear reinforcement, the load history and rate of loading, and the amount of reinforcement for out-of-plane confinement of the joint. Envelopes of the hysteretic behaviour of the specimens and the joint deformation under shear stress are presented. The stiffness degradation, the strain levels in the joint reinforcement, the contribution of joint, beam, and column to the inter-storey drift, and the energy dissipation were compared. All the test specimens reinforced with headed studs in the joint achieved considerable enhancement in their behaviour under cyclic loads and exhibited a performance close to that of a joint reinforced with closed hoops and cross ties according to the code. All the specimens with adequate out-of-plane confinement had an equivalent behaviour compared with the code-based specimen and achieved a desirable mode of failure. Use of double-headed studs proved to be a viable option for

    Fractures around the elbow joint comprise fractures of the distal humerus, the radial head, the olecranon and the coronoid process. Combined lesions are particularly demanding for the surgeon. Accurate knowledge of the anatomy and of the biomechanics is an essential requirement for a specific diagnosis and therapy. A stable and painless movable elbow joint is essential for most of the activities of daily living. Risk factors for the development of posttraumatic elbow joint arthrosis are non-anatomically reconstructed joint surfaces, axial malalignment of the joint axis and untreated concomitant injuries. Modern angular stable and anatomically preshaped implants facilitate a biomechanically adequate osteosynthesis and avoid or decrease functional impairment. In consideration of an increasing number of osteoporotic elbow joint fractures, endoprosthetic replacement has gained significance.

    Transmission towers are tall structures, usually a steel lattice tower, used to support an overhead power line. Usually, transmission towers are analyzed as frame-truss systems and the members are assumed to be pin-connected without explicitly considering the effects of joints on the tower behavior. In this research, an engineering example of joint will be analyzed with the consideration of the joint detailing to investigate how it will affect the tower analysis. A static analysis using STAAD Pro was conducted to indicate the joint with the maximum stress. This joint will then be explicitly analyzed in ANSYS using the Finite Element Method. Three approaches were used in the software which are the simple plate model, bonded contact with no bolts, and beam element bolts. Results from the joint analysis show that stress values increased with joint details consideration. This proves that joints and connections play an important role in the distribution of stress within the transmission tower.

    The theoretical analysis and model test are integrated to study the strength behavior of rock mass containing coplanar close intermittent joints in direct shear. Through introducing deformation compatibility equation in normal direction, the direct shear strength formulation is deducted based on the Mohr-Coulomb theory. According to the complete stress strain curve obtained from model tests, there are five typical stages in the failure process, namely linear elastic increment, slippage of the joints, steady development of post-cracking, the coalescence failure of discontinuous joints and the residual strength. The peak and residual strength increase with the increase of normal stress. There is no function to describe the relationship between deformation property and normal stress. The peak strength decreases with the increase of the joint connectivity rate, and the drop velocity is slow at low connectivity rate. The distribution of the joints also has influence on the strength of the rock mass. The similar material model test shows that the strength of model with joints on edge is bigger than that of the model with joints in the middle. The theoretical calculated results coincide well with experimental results.%采用理论分析同模型试验相结合的方法对共面闭合断续节理岩体的直剪强度特性进行研究.理论分析方面,引入法向变形协调条件,推导了模型的直剪强度公式.模型试验发现,全应力应变曲线主要经历了线弹性增长、节理面错动、次生裂纹起裂稳态扩展、节理面贯通破坏和残余强度五个阶段;峰值和残余强度都随正应力的增大而增大,而变形特性随正应力的变化规律性不强;峰值强度随节理连通率的增大而减小,低连通率时强度下降速度慢;节理两边分布的试样的强度普遍高于节理在中间的.对比发现,理论计算结果与试验值吻合较好.
