  9. Explosive Joining

    NASA Technical Reports Server (NTRS)

    1989-01-01

    Laurence J. Bement of Langley Research Center invented a technique to permit metal joining operations under hazardous or inaccessible conditions. The process, which provides a joint with double the strength of the parent metal, involves the use of very small quantities of ribbon explosive to create hermetically sealed joints. When the metal plates are slammed together by the explosion's force, joining is accomplished. The collision causes a skin deep melt and ejection of oxide films on the surfaces, allowing a linkup of electrons that produce superstrong, uniform joints. The technique can be used to join metals that otherwise would not join and offers advantages over mechanical fasteners and adhesives. With Langley assistance, Demex International Ltd. refined and commercialized the technology. Applications include plugging leaking tubes in feedwater heaters. Demex produces the small plugs, associated sleeves and detonators. The technology allows faster plugging, reduces downtime, cuts plugging costs and increases reliability.

  13. School Astronomy Club: from Project to Knowledge

    NASA Astrophysics Data System (ADS)

    Folhas, Alvaro

    2016-04-01

    Prepare a generation of young people for the challenges of the future is a task which forces us to rethink the school, not just for being difficult, but also because students feel that the school has very little to offer, especially something that interests them. Thus, the school is dysfunctional, is ill, and needs prompt treatment. School have to adjust to the new times, and this does not mean changing the old blackboards by advanced interactive whiteboards. The school has to find the way to the students with something that seduce them: the Challenge. The Astronomy Club that I lead in my school is essentially a Project space. Students who voluntarily joined the club, organize themselves according to their interests around projects whose outcome is not defined from the beginning, which requires them to do, undo and redo. Which obliges them to feel the need to ask for help to mathematics or physics to achieve answers, to feel the passion to study with a genuine purpose of learning. Some examples of the work: The younger students are challenged to reproduce the historical astronomical experiments that have opened the doors of knowledge such as the Eratosthenes experiment to determine the perimeter of the Earth (on equinox), or by using congruent triangles, determine the diameter the sun. These students are driven to establish distance scales in the solar system, which, to their astonishment, allows them to clear misconceptions that arise from some pictures of books and allows them to have a scientifically correct idea of the planetary orbit and distance separating the planets of the Solar System. For students from 15 to 18 years, I have to raise the level of the challenges and use the natural tendency of this age bracket to assert making new and exciting things. To this purpose, I am fortunate to have the support of large organizations like NUCLIO, ESA, CERN, and Go-Lab Project, Inspiring Science Education, Open Discovery Space and Global Hands on Universe.

  14. Joining the club: Conforming to and resisting biology in practice

    NASA Astrophysics Data System (ADS)

    Buxton, Cory Alexander

    2000-10-01

    This study explores how science and scientists were produced and reproduced within the setting of a university biology department. It builds upon recent work in anthropology of education and feminist science studies. My purpose was to look at both the contextual and constitutive values of science as they were negotiated and played out in the training of scientists in a setting where: (1) women were well represented in leadership positions; and (2) "mainstream" science was being both taught and practiced. Findings included the organization of a status hierarchy within the department, the meanings of science and scientists that students constructed within the social spaces they occupied, examples of individual resistance to certain norms of biology practice, and examples of institutional opposition to that resistance. There was some evidence that the unusually high representation of women in positions of leadership in the biology department did result in changes in both the contextual and constitutive values of how science was conceptualized, practiced and taught in this setting. Contextually, social spaces controlled by women were likely to emphasize: (1) teamwork bringing together participants with varied backgrounds and perspectives; (2) flexible and collaborative use of physical space; and (3) willingness to do work for which they went unacknowledged or to share rewards equally even when the work distribution was not equitable. Constitutively, these social spaces were prone to: (1) interdisciplinary synthesis and comprehensive approaches; (2) the study of topics that reconsidered beliefs about gender roles in plant and animal reproduction; (3) work that would be slower and take longer to produce (and publish) but might make a large contribution (be a high quality product) eventually; and (4) an awareness by women that their practices were different in some ways than the practices of their male colleagues.

    1991-08-01

    A workshop to obtain input from industry on the establishment of the Precision Joining Center (PJC) was held on July 10--12, 1991. The PJC is a center for training Joining Technologists in advanced joining techniques and concepts in order to promote the competitiveness of US industry. The center will be established as part of the DOE Defense Programs Technology Commercialization Initiative, and operated by EG G Rocky Flats in cooperation with the American Welding Society and the Colorado School of Mines Center for Welding and Joining Research. The overall objectives of the workshop were to validate the need for a Joining Technologists to fill the gap between the welding operator and the welding engineer, and to assure that the PJC will train individuals to satisfy that need. The consensus of the workshop participants was that the Joining Technologist is a necessary position in industry, and is currently used, with some variation, by many companies. It was agreed that the PJC core curriculum, as presented, would produce a Joining Technologist of value to industries that use precision joining techniques. The advantage of the PJC would be to train the Joining Technologist much more quickly and more completely. The proposed emphasis of the PJC curriculum on equipment intensive and hands-on training was judged to be essential.

    DOEpatents

    Tucker, Michael C; Lau, Grace Y; Jacobson, Craig P

    2012-10-16

    A method of joining dissimilar materials having different ductility, involves two principal steps: Decoration of the more ductile material's surface with particles of a less ductile material to produce a composite; and, sinter-bonding the composite produced to a joining member of a less ductile material. The joining method is suitable for joining dissimilar materials that are chemically inert towards each other (e.g., metal and ceramic), while resulting in a strong bond with a sharp interface between the two materials. The joining materials may differ greatly in form or particle size. The method is applicable to various types of materials including ceramic, metal, glass, glass-ceramic, polymer, cermet, semiconductor, etc., and the materials can be in various geometrical forms, such as powders, fibers, or bulk bodies (foil, wire, plate, etc.). Composites and devices with a decorated/sintered interface are also provided.

    2013-01-01

    Tubular objects having two or more concentric layers that have different properties are joined to one another during their manufacture primarily by compressive and friction forces generated by shrinkage during sintering and possibly mechanical interlocking. It is not necessary for the concentric tubes to display adhesive-, chemical- or sinter-bonding to each other in order to achieve a strong bond. This facilitates joining of dissimilar materials, such as ceramics and metals.

    2014-01-01

    In recent decades, methamphetamine developed a peculiar geographic distribution in the United States, with limited diffusion in the Northeast. While use within gay clubs received attention, methamphetamine in club subcultures more broadly remains less clear. Using quantitative and qualitative data, we provide a descriptive assessment of methamphetamine use in club subcultures. Methamphetamine use in club subcultures often has instrumental purposes. The context of initiation into methamphetamine use and its close connection to cocaine shape later patterns of use. Viewing meth solely as a gay party drug misses a significant part of the population and may misguide public health strategies to reduce methamphetamine use in the Northeast. PMID:23848380

  13. The Supernova Club: Urban Youth Engagement that Works

    NASA Astrophysics Data System (ADS)

    Sakimoto, Philip J.; Luckey, V.; Balsara, D.

    2008-05-01

    One of IYA's goals is to promote greater involvement by underrepresented minorities in scientific and engineering careers. IYA can serve as a catalyst for such involvement, but ultimate success requires a longer-term approach. The Supernova Club is an experiment in such a long-term approach. The goal is to see if engagement in a year-round astronomy club can propel youths from some of the most severely disadvantaged areas of our region into careers in science. We recruited club members by bringing astronomy activities to over a hundred youths ages 10-16 who were on campus in Summer 2007 for Notre Dames’ National Youth Sports Program (NYSP). Approximately 20 percent of the participants, most of who were underrepresented minorities and from below poverty level, expressed interest in joining an after-school astronomy club, and thirteen of them ultimately did so. The club meets one evening a week at Notre Dame's Robinson Community Learning Center. Center staff provide extensive support with logistics, meals, training in social skills and conduct, and communications with parents. Notre Dame scientists, assisted by local teachers, provide weekly activities. After one year, the club members have shown large improvements in interest in science and astronomy, ability to focus on tasks or discussions, and general behavior at school and at home. Funding for this first pilot year was provided through education supplements to HST research grants. With NASA space science education funding currently on an indefinite stand down, we are seeking other funds with which to carry on this experiment.

    1995-12-31

    A new method for plasma enhanced microwave joining of high purity (99.8%) alumina has been developed. The controlled application of a plasma between the adjoining surfaces of two rods initially heats the microwave-low-absorbing alumina rods to temperatures high enough for them to absorb microwave energy efficiently. With this technology, the adjacent surfaces of alumina rods can be melted and welded together in less than three minutes using approximately 400 watts of microwave energy. Four point bending tests measured fracture strengths of up to 130 MPa at the joined interface. Optical and SEM micrographs indicated that exaggerated grain growth prevailed for all joints studied.

    Abstract Problem addressed In Canada, there are few health promotion programs for men, particularly programs focused on indigenous and other men marginalized by social and structural inequities. Objective of program To build solidarity and brotherhood among vulnerable men; to promote health through education, dialogue, and health screening clinics; and to help men regain a sense of pride and fulfilment in their lives. Program description The DUDES Club was established in 2010 as a community-based health promotion program for indigenous men in the Downtown Eastside neighbourhood of Vancouver, BC. Between August 2014 and May 2015, 150 men completed an evaluation survey developed using a logic model approach. Responses were analyzed based on the 4 dimensions of the indigenous medicine wheel (mental, physical, emotional, and spiritual). Evaluation results demonstrated high participant satisfaction and positive outcomes across all 4 dimensions of health and well-being: 90.6% of respondents indicated that the DUDES Club program improved their quality of life. Participants who attended meetings more often experienced greater physical, mental, and social benefits (P < .05). Conclusion Findings indicate that this innovative model is effective in promoting the well-being of mainly indigenous men through culturally safe services in an urban community.

    A method for joining shapes of ceramic materials together to form a unitary ceramic structure. In the method of the invention, a mixture of two or more chemical components which will react exothermically is placed between the surfaces to be joined, and the joined shapes heated to a temperature sufficient to initiate the exothermic reaction forming a joining material which acts to bond the shapes together. Reaction materials are chosen which will react exothermically at temperatures below the degradation temperature of the materials to be joined. The process is particularly suited for joining composite materials of the silicon carbide-silicon carbide fiber type.

    An upper plate having ink flow channels and a lower plate having a multicolored pattern are joined. The joining is accomplished without clogging any ink flow paths. A pattern having different colored parts and apertures is formed in a lower plate. Ink flow channels each having respective ink input ports are formed in an upper plate. The ink flow channels are coated with solder mask and the bottom of the upper plate is then coated with solder. The upper and lower plates are pressed together at from 2 to 5 psi and heated to a temperature of from 295 F to 750 F or enough to melt the solder. After the plates have cooled and the pressure is released, the solder mask is removed from the interior passageways by means of a liquid solvent.

  5. Recent progress in ceramic joining

    SciTech Connect

    Loehman, R.E.

    1998-09-01

    Both fundamental and practical aspects of ceramic joining are understood well enough for many, if not most, applications requiring moderate strengths at room temperature. This paper argues that the two greatest needs in ceramic joining are for techniques to join buried interfaces by selective heating, and methods for joining ceramics for use at temperatures of 800 to 1,200 C. Heating with microwave radiation or with high-energy electron beams has been used to join buried ceramic interfaces, for example SiC to SiC. Joints with varying levels of strength at temperatures of 600 to 1,000 C have been made using four techniques: (1) transient liquid phase bonding; (2) joining with refractory braze alloys; (3) joining with refractory glass compositions; and (4) joining using preceramic polymers. Joint strengths as high as 550 MPa at 1,000 C have been reported for silicon nitride-silicon nitride bonds tested in four-point flexure.

With an introduction on the applications, advantages and limitations in the use of this metal the following topics will be discussed in this handbook: physical, thermal, and nuclear properties; extraction from the ores; purification and casting of ingots; production and types of beryllium powders; consolidation methods, grades, and properties; mechanical properties with emphasis on the various factors affecting these properties; forming and mechanical working; welding, brazing, bonding, and fastening; machining; powder deposition; corrosion; health aspects; and examples of production of components. This report consists of ''Section X--Joining'' from the handbook. The prefix X is maintained here for the figures, tables and references. In this section the different methods used for joining beryllium and the advantages, disadvantages and limitations of each are presented. The methods discussed are fusion welding, brazing, solid state bonding (diffusion bonding and deformation bonding), soldering, and mechanical fastening. Since beryllium has a high affinity for oxygen and nitrogen with the formation of oxides and nitrides, considerable care must be taken on heating the metal, to protect it from the ambient atmosphere. In addition, mating surfaces must be cleaned and joints must be designed to minimize residual stresses as well as locations for stress concentration (notch effects). In joining any two metals the danger exists of having galvanic corrosion if the part is subjected to moisture or to any type of corroding environment. This becomes a problem if the less noble (anodic) metal has a significantly smaller area than the more noble (cathodic) metal since the ions (positive charges) from the anodic (corroding) metal must correspond to the number of electrons (negative charges) involved at the cathode. Beryllium is anodic to almost

  10. The Irish brawn drain: English League clubs and Irish footballers, 1946-1995.

    McGovern, P

    2000-09-01

    This paper draws on world systems and resource dependency theories to show how the changing recruitment practices of English League clubs have deepened the brawn drain from Irish football, thereby compounding its underdevelopment. An analysis of the origins, method of recruitment and destinations of Irish players (North and South) who appeared in the English League between 1946 and 1995 shows that English clubs imported large numbers of Irish players throughout the second half of the twentieth century. However, it was the inclusion of Irish teenagers within the youth policies of the largest clubs in the period after the 1970s that marked a break from the traditional pattern of buyer-supplier relations. Instead of continuing to purchase players who had established reputations within the Irish leagues, English clubs began to hire the most promising schoolboys before they joined Irish sides. As this practice spread, it eventually eliminated a valuable source of income: the selling of players to English clubs. Despite this development it would, however, be inappropriate to view the relationship between the Irish and English football industries as a simple zero sum game as Irish clubs benefit from employing highly trained young players who return home after failing to establish careers in England.

    A midwifery student book club was set up at University Campus Suffolk (UCS) with the aim of engaging students in alternative forms of literature relevant to their studies and to enhance their university experience. The book club was well attended by first and second year midwifery students, but less so by third years. There was evidence of informal student engagement with the lecturer through follow up emails about the meetings. Most of the books reviewed were enjoyed, but the responsibility of suggesting a book for their peers to review was deemed too much by some students.

  20. A fast neighbor joining method.

    PubMed

    Li, J F

    2015-01-01

    With the rapid development of sequencing technologies, an increasing number of sequences are available for evolutionary tree reconstruction. Although neighbor joining is regarded as the most popular and fastest evolutionary tree reconstruction method [its time complexity is O(n(3)), where n is the number of sequences], it is not sufficiently fast to infer evolutionary trees containing more than a few hundred sequences. To increase the speed of neighbor joining, we herein propose FastNJ, a fast implementation of neighbor joining, which was motivated by RNJ and FastJoin, two improved versions of conventional neighbor joining. The main difference between FastNJ and conventional neighbor joining is that, in the former, many pairs of nodes selected by the rule used in RNJ are joined in each iteration. In theory, the time complexity of FastNJ can reach O(n(2)) in the best cases. Experimental results show that FastNJ yields a significant increase in speed compared to RNJ and conventional neighbor joining with a minimal loss of accuracy. PMID:26345805

    Derby, B.; Miodownik, M.

    1999-04-01

    Hot Isostatic Pressing (HIP) is investigated as a technique for joining the cermet WC-15% Co to itself. Encapsulation of the specimens prior to HIPing was carried out using steel encapsulation, glass encapsulation and self encapsulation. The bonds were evaluated using a four point bend method. It is shown that the glass and steel encapsulation methods have a number of inherent problems which make them inappropriate for near net shape processing. In contrast the novel self encapsulation method, described for the first time in this communication, is both simple and effective, producing joined material with bulk strength. The concept of self encapsulation is potentially widely applicable for joining composite materials.

    Adhesive joining offers one method of assembling products. Advantages of adhesive joining/assembly include distribution of applied forces, lighter weight, appealing appearance, etc. Selecting environmentally safe adhesive materials and accompanying processes is paramount in today`s business climate if a company wants to be environmentally conscious and stay in business. Four areas of adhesive joining (adhesive formulation and selection, surface preparation, adhesive bonding process, waste and pollution generation/cleanup/management) all need to be carefully evaluated before adhesive joining is selected for commercial as well as military products. Designing for six sigma quality must also be addressed in today`s global economy. This requires material suppliers and product manufacturers to work even closer together.

    Club drug use and correlates were examined among 251 Hispanic college students on the Texas - México border. Participants completed questionnaires on substance use, club drug attitudes and beliefs, sexual risk-taking behaviors, depressive symptoms, and acculturation. One-quarter of participants reported club drug use. Regression analyses demonstrated that frequency and history of lifetime use were consistently associated with more permissive drug attitudes and other substance use but not sexual risk-taking, depression symptoms, or acculturation. Acculturation was negatively associated with frequency of club drug use, yet positively associated with use of other illicit substances. Avenues for future studies are suggested. PMID:20653638

    Two years ago John Kinchin and myself were lucky enough to attend the Goldsmith's particle physics course. As well as many interesting lectures and activities, this course included a visit to CERN. To most physics teachers CERN is Mecca, a hallowed place where gods manipulate and manufacture matter. The experience of being there was even better. Alison Wright was an enthusiastic and very knowledgeable host who ensured the visit went smoothly and we all learned a lot. While we were there, John and I discussed the possibility of bringing a party of A-level students to see real physics in action. In February of this year we managed it. 33 students from two schools, Boston Grammar School and Northampton School for Boys, and four staff left England and caught the 2 am ferry to France. Many hours and a few `short cuts' later we arrived at our hotel in St Genis, not far from CERN. The first day was spent sight-seeing in Lausanne and Geneva. The Olympic museum in Lausanne is well worth a visit. Unfortunately, the famous fountain in Geneva was turned off, but then you can't have everything. The following morning we turned up at CERN late due to the coach's brakes being iced up! We were met once again by Alison Wright who forgave us and introduced the visit by giving an excellent talk on CERN, its background and its reason for existing. At this point we met another member of our Goldsmith's course and his students so we joined forces once again. We then piled back into the coach to re-cross the border and visit ALEPH. ALEPH is a monster of a detector 150 m below ground. We divided into four groups, each with a very able and knowledgeable guide, and toured the site. The size and scale of the detector are awesome and the students were suitably impressed. We repeated the speed of sound experiment of two years ago at the bottom of a 150 m concrete shaft (320 m s-1), posed for a group photo in front of the detector (figure 1) and returned to the main site for lunch in

    Bement, Laurence J. (Inventor); Perry, Ronnie B. (Inventor)

    1997-01-01

    The invention is an apparatus and method for wire splicing using an explosive joining process. The apparatus consists of a prebend, U-shaped strap of metal that slides over prepositioned wires. A standoff means separates the wires from the strap before joining. An adhesive means holds two ribbon explosives in position centered over the U-shaped strap. A detonating means connects to the ribbon explosives. The process involves spreading strands of each wire to be joined into a flat plane. The process then requires alternating each strand in alignment to form a mesh-like arrangement with an overlapped area. The strap slides over the strands of the wires. and the standoff means is positioned between the two surfaces. The detonating means then initiates the ribbon explosives that drive the strap to accomplish a high velocity. angular collision between the mating surfaces. This collision creates surface melts and collision bonding resulting in electron-sharing linkups.

    2009-01-01

    SUMMARY The purpose of this article is to examine the current health promotion orientation of youth sports clubs in Finland in view of the standards created previously for the health promoting sports club (HPSC). Ninety-seven youth sports clubs participated, and 273 sports club officials and 240 coaches answered the questionnaires. To describe clubs health promotion orientations, an HPSC index was created. The HPSC index was formulated on sub-indices by factor analysis. The sub-indices were: policy, ideology, practice and environment indexes. The results indicate that youth sports clubs are fairly health promoting in general. On average, the clubs fulfilled 12 standards for HPSC out of 22. Every fourth club was categorized as higher health promoting (≥ 15 fulfilled standards), and every third as lower health promoting (<11 fulfilled standards). The variation between clubs was wide. The clubs that had been recognized as exemplary and hence certified by the Young Finland Association were more likely to recognize health promotion than non-certified clubs (OR = 2.36, p = 0.016). The sports club officials were twice as likely to evaluate their clubs as higher health promoting than the coaches (OR = 2.04, p = 0.041). Under the sub-indices, ideologies were recognized best, others less. These findings indicate that minority of the youth sports clubs have realized health promotion comprehensively as a part of their activities. There is a lot of need for development, especially in the area of health promotion policies and practices. The instruments used proved valid and reliable and can therefore be recommended for international use. PMID:19136676

    1995-09-26

    Objective was to assess techniques for joining NZP ceramics, a new family of ceramic materials that have low coefficient of thermal expansion, low thermal conductivity, and excellent thermal-shock resistance. Initially, the authors evaluated laser-beam welding over volatile fluxing agents (ferric oxide, copper oxide, boric acid, and boron nitride). They also examined other laser, arc-welding, brazing, and cold joining techniques. The NZP materials were capable of sustaining the thermal stresses associated with these joining processes without substantial cracking. Of the volatile fluxes, only the copper oxide promoted weld fusion. Efforts to accomplish fusion by laser-beam welding over copper, titanium, stainless steel, yttrium barium copper oxide, fused silica glass, and mullite/alumina were unsuccessful. Gas-tungsten arc welding accompanied by porosity, irregularities, and cracking was achieved on copper sheet sandwiched between NZP tiles. Attempts at conventional oxy-acetylene welding and torch brazing were unproductive. Silica-based oxide mixtures and copper oxide-based materials show potential for development into filler materials for furnace brazing, and phosphate-based cements show promise as a means of cold joining.

    2002-01-01

    I recently took on a new assignment and, as is my norm, I scheduled a series of one-hour, 1:1 join-up meetings with the various lead personnel on the team and their hierarchy. During one of these meetings, the person I was meeting with informed me how pleasantly surprised she was that I had scheduled this meeting as very few individuals took the time anymore to have them. I was shocked. I was taught that establishing a 1:1 relationship with the people on your team is critical to the project's success. This was the first time I'd heard anything like this about join-up meetings. I filed this feedback away. Later I was talking to my project manager-mentor, and he indicated he had finished his join-up meetings with every person in his new organization. He also indicated his predecessor had conducted few, if any, join-up meetings. Again, I was shocked. When I reflected on these two experiences, I realized a very negative trend might be emerging in our fast-paced, schedule-driven, 500-e-mail-per-day, cell-phone -ringing, 24/7 -communication, multi-tasking work lives: NO FACE TIME! Face time is what you spend with people to talk about the project you are working on, their expectations of you, your expectations of them, your hierarchy's expectations about each of you, and/or-last but certainly not least-what each of you plans on achieving during the project. A 1:1, face-to-face, join-up meeting is the only way I know to build solid trust between the project manager and the team members and their hierarchy.

    2012-08-01

    We have found an optical/X-ray counterpart candidate for the bright, but presently unidentified, Fermi source 2FGL J1311.7-3429. This counterpart undergoes large-amplitude quasi-sinusoidal optical modulation with a 1.56 hr (5626 s) period. The modulated flux is blue at peak, with T{sub eff} Almost-Equal-To 14, 000 K, and redder at minimum. Superimposed on this variation are dramatic optical flares. Archival X-ray data suggest modest binary modulation, but no eclipse. With the {gamma}-ray properties, this appears to be another black-widow-type millisecond pulsar. If confirmation pulses can be found in the GeV data, this binary will have the shortest orbital period of any known spin-powered pulsar. The flares may be magnetic events on the rapidly rotating companion or shocks in the companion-stripping wind. While this may be a radio-quiet millisecond pulsar, we show that such objects are a small subset of the {gamma}-ray pulsar population.

    The shortage of suitable donor organs is the most significant single limiting factor in transplant programmes. More lives could be saved or immeasurably improved if more organs were available. I look at two traditional solutions to the shortfall, and suggest that they are ineffective and/or offensive, and consider the features common to any answer to the problem. I then suggest a third solution: that admission to future transplant lists be conditional on registration as a potential organ donor, outlining its benefits, and defending it against one possible objection.

    The gap between production and implementation of knowledge is the main reason for the suboptimal quality of health care. To eliminate this gap and improve the quality of patient care, journal club (JC) in graduate medical education provides an opportunity for learning the skills of evidence-based medicine. JC, however, continues to face many challenges mainly due to poorly defined goals, inadequate preparation, and lack of interest. This article presents an innovative model to prepare and present JC based on three pillars: dialogical learning through group discussion, mentored residents as peer teachers, and including JC as part of a structured curriculum to learn evidence-based medicine. This engaging model has the potential to transform JC from a moribund session that is daunting for residents into a lively discussion to redefine clinical practice using the most current evidence.

    1990-11-01

    Under ideal conditions load bearing structures would be designed without joints, thus eliminating a source of added weight, complexity and weakness. In reality the need for accessibility, repair, and inspectability, added to the size limitations imposed by the manufacturing process and transportation/assembly requirements mean that some minimum number of joints will be required in most structures. The designer generally has two methods for joining fiber composite materials, adhesive bonding and mechanical fastening. As the use of thermoplastic materials increases, a third joining technique -- welding -- will become more common. It is the purpose of this document to provide a review of the available sources pertinent to the design of joints in fiber composites. The primary emphasis is given to adhesive bonding and mechanical fastening with information coming from documentary sources as old as 1961 and as recent as 1989. A third, shorter section on composite welding is included in order to provide a relatively comprehensive treatment of the subject.

    This invention is a lightweight, universal connector that joins stringers at various angles. The connectors 10 are fabricated from fiber-epoxy resin strips that wrap around stringers 30 and have ends, tabs 16 and 18, which extend in one general direction. The inside surface of the first tab 16 lies on a plane defined by the stringers being joined, and the second tab 18 is separated from the first tab 16 by a distance equal to their thickness. Stringers 30 of different shapes and sizes are joined by alternately bonding the first tab 16 of one connector between the first 16 and second 18 tabs of another connector. Tee-joints are formed by using web elements 41 and 42 which each partially wrap around a stringer 3010 and have tabs 411 and 421 which are offset, and are bonded between tabs 16 and 18 of universal connectors 109 and 1010 bonded to another stringer 309. Sharp corners are trimmed from the tabs so that a gusset area remains between the stringers for support. Acute angle through obtuse angle joints are formed by trimming those edges of the tabs which lie against the stringers. A specific application of the invention is a Walker 60, utilized by handicapped individuals, fabricated from composite materials that is 40% lighter than similar metallic structures.

  14. Joining forces, joining futures: hospice at the crossroads.

    PubMed

    Pietroburgo, Julie

    2004-01-01

    Faced with health-policy changes, increased competition, and limited funding, hospices must either find more efficient ways to provide end-of-life care or risk organizational demise. Increasingly, hospices are re-evaluating their organizations to stretch resources and remain viable. Prevalent restructuring options for addressing environmental pressures are integration, alliance, and collaboration with other organizations. This study examines the restructuring phenomenon by evaluating trends among nonprofit hospices in six states. The study identifies demographic characteristics predictive of organizational decisions to join forces, and it examines the dominant political and economic reasons that propel or impede restructuring decisions. In addition, the study evaluates the results of restructuring actions.

    1980-01-01

    2 more women's clubs have been opened by the Family Planning Association of Hong Kong following the success of the 1st such club at Yue Taipo organized in September 1970. The 2nd club is located at the Hing Shing Temporary Housing Area in Kwai Chung and caters to new residents. The 3rd, established January 4, 1980, is located at the Fortune Street Temporary Housing Area in Cheung Sha Wan. The overall aim of these clubs is to give a boost to the quality of family life through organized educational and recreational facilities. Activities at both clubs were initiated by formal opening ceremonies presided over by representatives of the Housing Estates and Family Planning Association. Welcoming wellwishers at each ceremony, Mrs. Peggy Lam, Acting Director of the Family Planning Association of Hong Kong; drew attention to the important contribution made by family planning to the well being of families. It was through the wise planning of their families that parents were provided with ample time and energy for the upbringing of chilren, said Mrs. Lam. The activities of the women's clubs include instruction on traditional women's activities, and talks on sanitation, childrearing, interpersonal relations, nutrition, and permanent contraception. Mrs. Lam felt that the fact that 79% of married women of childbearing age in Hing Shing were practicing family planning was most encouraging.

    In order to ease the management of their infrastructure, most of the WLCG sites are adopting cloud based strategies. In the case of CERN, the Tier 0 of the WLCG, is completely restructuring the resource and configuration management of their computing center under the codename Agile Infrastructure. Its goal is to manage 15,000 Virtual Machines by means of an OpenStack middleware in order to unify all the resources in CERN's two datacenters: the one placed in Meyrin and the new on in Wigner, Hungary. During the commissioning of this infrastructure, CERN IT is offering an attractive amount of computing resources to the experiments (800 cores for ATLAS and CMS) through a private cloud interface. ATLAS and CMS have joined forces to exploit them by running stress tests and simulation workloads since November 2012. This work will describe the experience of the first deployments of the current experiment workloads on the CERN private cloud testbed. The paper is organized as follows: the first section will explain the integration of the experiment workload management systems (WMS) with the cloud resources. The second section will revisit the performance and stress testing performed with HammerCloud in order to evaluate and compare the suitability for the experiment workloads. The third section will go deeper into the dynamic provisioning techniques, such as the use of the cloud APIs directly by the WMS. The paper finishes with a review of the conclusions and the challenges ahead.

    Reported herein is the final report on a U.S. Department of Energy (DOE) Advanced Manufacturing Office (AMO) project with industry cost-share that was jointly carried out by Oak Ridge National Laboratory (ORNL), ExxonMobil Upstream Research Company (ExxonMobil), and MegaStir Technologies (MegaStir). The project was aimed to advance the state of the art of friction stir welding (FSW) technology, a highly energy-efficient solid-state joining process, for field deployable, on-site fabrications of large, complex and thick-sectioned structures of high-performance and high-temperature materials. The technology innovations developed herein attempted to address two fundamental shortcomings of FSW: 1) the inability for on-site welding and 2) the inability to weld thick section steels, both of which have impeded widespread use of FSW in manufacturing. Through this work, major advance has been made toward transforming FSW technology from a “specialty” process to a mainstream materials joining technology to realize its pervasive energy, environmental, and economic benefits across industry.

  1. Monitoring Evolution at CERN

    NASA Astrophysics Data System (ADS)

    Andrade, P.; Fiorini, B.; Murphy, S.; Pigueiras, L.; Santos, M.

    2015-12-01

    Over the past two years, the operation of the CERN Data Centres went through significant changes with the introduction of new mechanisms for hardware procurement, new services for cloud provisioning and configuration management, among other improvements. These changes resulted in an increase of resources being operated in a more dynamic environment. Today, the CERN Data Centres provide over 11000 multi-core processor servers, 130 PB disk servers, 100 PB tape robots, and 150 high performance tape drives. To cope with these developments, an evolution of the data centre monitoring tools was also required. This modernisation was based on a number of guiding rules: sustain the increase of resources, adapt to the new dynamic nature of the data centres, make monitoring data easier to share, give more flexibility to Service Managers on how they publish and consume monitoring metrics and logs, establish a common repository of monitoring data, optimise the handling of monitoring notifications, and replace the previous toolset by new open source technologies with large adoption and community support. This contribution describes how these improvements were delivered, present the architecture and technologies of the new monitoring tools, and review the experience of its production deployment.

    CERN IT DSS operates the main storage resources for data taking and physics analysis mainly via three system: AFS, CASTOR and EOS. The total usable space available on disk for users is about 100 PB (with relative ratios 1:20:120). EOS actively uses the two CERN Tier0 centres (Meyrin and Wigner) with 50:50 ratio. IT DSS also provide sizeable on-demand resources for IT services most notably OpenStack and NFS-based clients: this is provided by a Ceph infrastructure (3 PB) and few proprietary servers (NetApp). We will describe our operational experience and recent changes to these systems with special emphasis to the present usages for LHC data taking, the convergence to commodity hardware (nodes with 200-TB each with optional SSD) shared across all services. We also describe our experience in coupling commodity and home-grown solution (e.g. CERNBox integration in EOS, Ceph disk pools for AFS, CASTOR and NFS) and finally the future evolution of these systems for WLCG and beyond.

    (Atacama Large Millimeter Array) in Chile and the very large optical/infrared telescopes now undergoing conceptual studies. ESO membership will give UK astronomers access to the suite of four world-class 8.2-meter VLT Unit Telescopes at the Paranal Observatory (Chile), as well as other state-of-the-art facilities at ESO's other observatory at La Silla. Through PPARC the UK already participates in joint collaborative European science programmes such as CERN and the European Space Agency (ESA), which have already proved their value on the world scale. Joining ESO will consolidate this policy, strengthen ESO and enhance the future vigour of European astronomy. Statements Commenting on the funding announcement, Prof. Ian Halliday , PPARC's CEO, said that " this new funding will ensure our physicists and astronomers remain at the forefront of international research - leading in discoveries that push back the frontiers of knowledge - and the UK economy will also benefit through the provision of highly trained people and the resulting advances in IT and commercial spin-offs ". Prof. Mike Edmunds , UCW Cardiff, and Chairman of the UK Astronomy Review Panel which recently set out a programme of opportunities and priorities for the next 10 - 20 years added that " this is excellent news for UK science and lays the foundation for cutting edge research over the next ten years. British astronomers will be delighted by the Government's rapid and positive response to their case. " Speaking on behalf of the ESO Organisation and the community of more than 2500 astronomers in the ESO member states [2], the ESO Director General, Dr. Catherine Cesarsky , declared: "When ESO was created in 1962, the UK decided not to join, because of access to other facilities in the Southern Hemisphere. But now ESO has developed into one of the world's main astronomical organisations, with top technology and operating the VLT at Paranal, the largest and most efficient optical/infrared telescope facility in the

  13. The SPL at CERN

    NASA Astrophysics Data System (ADS)

    Garoby, R.

    2005-06-01

    The Superconducting Proton Linac (SPL) is a multi-GeV, multi-MW linear proton machine which represents a very interesting option for the future of CERN. Operating at 50 Hz, it will serve both as a high performance injector for the complex of high energy accelerators, replacing the present PS booster, and as a high power proton driver for other physics applications like the generation of muons and neutrinos and/or radio-active ions. The potential of the SPL is presently being scrutinized and compared to other alternatives. A path of evolution is considered, beginning with the realization of a 3 MeV test facility, followed by the building of the 160 MeV front end of the SPL and finishing with the construction of the complete linac. The status of these investigations and the progress towards the SPL are summarized in this paper.

  14. Golf players exhibit changes to grip speed parameters during club release in response to changes in club stiffness.

    PubMed

    Osis, Sean T; Stefanyshyn, Darren J

    2012-02-01

    The influence of golf club stiffness on driving performance is currently unclear, and it is possible that this ambiguity is due in part to golfer adaptation to equipment. The purpose of the current study was to elucidate mechanisms of adaptation to club stiffness, during the golf swing, by employing tendon vibration to distort proprioceptive feedback. Vibration (∼50 Hz, ∼1 mm amplitude) was applied to the upper extremities of 24 golfers using DC motors with eccentric weights. Golfers hit golf balls in a laboratory setting using three clubs of varying shaft stiffness, and club kinematics were recorded using high speed (180 Hz) digital cameras. The results demonstrated significant slowing of the club grip during club release for a high-stiffness shaft with vibration. This suggests that, when proprioceptive feedback is available, players adapt to changes in club stiffness by modifying the release dynamics of the club late in the downswing. PMID:21820748

  4. Affordable, Robust Ceramic Joining Technology (ARCJoint) Developed

    NASA Technical Reports Server (NTRS)

    Steele, Gynelle C.

    2001-01-01

    Affordable, Robust Ceramic Joining Technology (ARCJoint) is a method for joining high temperature- resistant ceramic pieces together, establishing joints that are strong, and allowing joining to be done in the field. This new way of joining allows complex shapes to be formed by joining together geometrically simple shapes. The joining technology at NASA is one of the enabling technologies for the application of silicon-carbide-based ceramic and composite components in demanding and high-temperature applications. The technology is being developed and tested for high-temperature propulsion parts for aerospace use. Commercially, it can be used for joining ceramic pieces used for high temperature applications in the power-generating and chemical industries, as well as in the microelectronics industry. This innovation could yield big payoffs for not only the power-generating industry but also the Silicon Valley chipmakers. This technology, which was developed at the NASA Glenn Research Center by Dr. Mrityunjay Singh, is a two-step process involving first using a paste to join together ceramic pieces and bonding them by heating the joint to 110 to 120 C for between 10 and 20 min. This makes the joint strong enough to be handled for the final joining. Then, a silicon-based substance is applied to the joint and heated to 1400 C for 10 to 15 min. The resulting joint is as strong as the original ceramic material and can withstand the same high temperatures.

    Journal clubs are an integral element of residency training. We report the successful implementation of a monthly structured journal club in our anesthesia residency program. Based on resident surveys before and one year after its start, the journal club led to a significantly higher confidence in how to critically appraise literature and present a manuscript. The journal club also improved the residents' ability to search the literature and their statistical knowledge, skills that are essential in the practice of evidence-based medicine. We describe key features that may aid other training programs in organizing a stimulating an educational and sustainable journal club. PMID:24358844

  2. Efficient Joins with Compressed Bitmap Indexes

    Computational Research Division; Madduri, Kamesh; Wu, Kesheng

    2009-08-19

    We present a new class of adaptive algorithms that use compressed bitmap indexes to speed up evaluation of the range join query in relational databases. We determine the best strategy to process a join query based on a fast sub-linear time computation of the join selectivity (the ratio of the number of tuples in the result to the total number of possible tuples). In addition, we use compressed bitmaps to represent the join output compactly: the space requirement for storing the tuples representing the join of two relations is asymptotically bounded by min(h; n . cb), where h is the number of tuple pairs in the result relation, n is the number of tuples in the smaller of the two relations, and cb is the cardinality of the larger column being joined. We present a theoretical analysis of our algorithms, as well as experimental results on large-scale synthetic and real data sets. Our implementations are efficient, and consistently outperform well-known approaches for a range of join selectivity factors. For instance, our count-only algorithm is up to three orders of magnitude faster than the sort-merge approach, and our best bitmap index-based algorithm is 1.2x-80x faster than the sort-merge algorithm, for various query instances. We achieve these speedups by exploiting several inherent performance advantages of compressed bitmap indexes for join processing: an implicit partitioning of the attributes, space-efficiency, and tolerance of high-cardinality relations.

    2011-10-01

    After School Astronomy clubs are unique in focusing on children in the K-12 grades as opposed to the numerous Amateur Astronomy Clubs within the US and abroad whose membership is largely adult focused. Over the last 12 years, we have identified over 140 clubs that were previously running in isolation, provided them with science and education resources and a means to communicate, created an online community of after School Astronomy Clubs, and facilitated the development of new clubs. Over this time, our model for developing and running these clubs has changed as we gained experience with various target populations, educational settings, and external partners and as best practices have emerged regarding engagement, impact, pedagogy, and sustainability. This talk will highlight these experiences and practices and discuss implications for future development of the After School Astronomy Club program.

  4. Breakfast Clubs: Starting the Day in a Positive Way

    Graham, Pamela Louise; Russo, Riccardo; Defeyter, Margaret Anne

    2015-01-01

    Breakfast clubs are widely promoted as having a beneficial impact on children’s behavior at the start of the school day, which can be conducive to their learning within the classroom. However, the few available studies that have considered the impact of breakfast club attendance on children’s behavior have yielded mixed results and no studies to date have directly observed children’s behavior within the breakfast club setting. Using a combination of real-time observation and filmed breakfast club footage, the aims of the current study were to: (1) devise a set of observational criteria appropriate for use in the breakfast club setting; (2) investigate the occurrence of both positive and negative behaviors. A sample of 30 children aged between 3 and 11 years were recruited from 3, opportunistically sampled primary school breakfast clubs in the North East of England, UK. The behaviors they displayed within the breakfast club setting on two separate days were observed and coded for subsequent analysis. Results of the investigation showed that children’s behavior could be classified into three positive and three negative behavioral categories. Using these categories to code children’s behavior as they engaged in breakfast club showed that children displayed more positive than negative behaviors within the breakfast club setting and this was the case regardless of the type of activity (i.e., quiet or boisterous) children were involved in. Findings are discussed in relation to breakfast club policy, implementation, and evaluation. PMID:26217653

    A method is provided for joining a metallic member to a structure made of a composite matrix material. One or more surfaces of a portion of the metallic member that is to be joined to the composite matrix structure is provided with a plurality of outwardly projecting studs. The surface including the studs is brought into engagement with a portion of an uncured composite matrix material so that fibers of the composite matrix material intertwine with the studs, and the metallic member and composite structure form an assembly. The assembly is then companion cured so as to join the metallic member to the composite matrix material structure.

    Summarized is a literature survey of the methods for joining ceramics to ceramics or ceramics to metals for high temperature applications. Also mechanical properties and potential applications of the joints are considered. The joining of ceramics is usually carried out by brazing or diffusion bonding. Especially the latter has been found useful, increasing the application of bonded ceramics. The possibility of using electron beam and laser beam welding for joining ceramics has also recently been investigated. The bonding of ceramics has found numerous applications typical for high operating temperatures, i.e., sensors and thermocouples.

    The purpose of this work is to optimize the properties of SiC-SiC joints made using microwave energy. The current focus is on identification of the most effective joining methods for scale-up to large tube assemblies, including joining using SiC produced in situ from chemical precursors. During FY 1996, a new microwave applicator was designed, fabricated and tested that provides the capability for vacuum baking of the specimens and insulation and for processing under inert environment. This applicator was used to join continuous fiber-reinforced (CFCC) SiC/SiC composites using a polymer precursor to form a SiC interlayer in situ.

    We analyse the evolution of the online interactions held by college students and report on novel relationships between social structure and performance. Our results indicate that more frequent and intense social interactions generally imply better score for students engaging in them. We find that these interactions are hosted within a “rich-club”, mediated by persistent interactions among high performing students, which is created during the first weeks of the course. Low performing students try to engage in the club after it has been initially formed, and fail to produce reciprocity in their interactions, displaying more transient interactions and higher social diversity. Furthermore, high performance students exchange information by means of complex information cascades, from which low performing students are selectively excluded. Failure to engage in the rich club eventually decreases these students' communication activity towards the end of the course. PMID:23378908

Pint by pint, the fluid sciences, the precursors to geodynamics, were developed in the taprooms and clubs of the great nineteenth-century thinkers. They puffed their pipes, sipped their wine and ale, feasted on pies and porridge, satiating and saturating themselves in rising plumes of smoke and steam.

  11. The Sierra Club and immigration policy: a critique.

    PubMed

    Clarke, Alice L

    2001-03-01

    In 1998, the Sierra Club membership voted in a contentious referendum to refrain from including restriction of U.S. immigration as part of its official club population policy. Club proponents of immigration reduction had declared the problem was simply the environmental impact of greater numbers of people; however, they failed to distinguish themselves from groups with much broader immigration-reduction agendas, leaving themselves open to charges of racism. The club faction calling for the exclusion of immigration issues from the policy, on the other hand, failed to acknowledge the demographic reality of the contribution of immigration (30%) to the growth of the U.S. population. As a result, current club policy is not credible, as it calls for a reduction in the U.S. population but ignores immigration. The Sierra Club's complex organi- zational structure and open, democratic political process make it particularly vulnerable to internal conflict during periods of changing perspectives within the organization.

    The NASA Glenn Research Center initiated development of the Fuel Cell Powered Club Car Carryall as a way to reduce pollution in industrial settings, reduce fossil fuel consumption and reduce operating costs for transportation systems. The Club Car Carryall provides an inexpensive approach to advance the state of the art in electric vehicle technology in a practical application. The project transfers space technology to terrestrial use via non-traditional partners, and provides power system data valuable for future aeronautics and space applications. The work was done under the Hybrid Power Management (HPM) Program. The Carryall is a state of the art, dedicated, electric utility vehicle. Hydrogen powered proton exchange membrane (PEM) fuel cells are the primary power source. Ultracapacitors were used for energy storage as long life, maintenance free operation, and excellent low temperature performance is essential. Metal hydride hydrogen storage was used to store hydrogen in a safe and efficient low-pressure solid form. The report concludes that the Fuel Cell Powered Club Car Carryall can provide excellent performance, and that the implementation of fuel cells in conjunction with ultracapacitors in the power system can provide significant reliability and performance improvements.

    1997-11-01

    The advent of new materials for engineering applications almost always brings a new challenge: how will these new materials be joined to a larger engineering structure? New ceramic materials are being developed for a wide variety of applications in areas such as power generation, energy conversion, automotive and aerospace, with specific applications including heat exchangers, fuel cells, turbocharger rotors, combustor liners, and for many other applications. Typically the new materials will be exposed to more hostile environments with respect to temperature, corrosion, and stress than materials in the past, and thus, many of the conventional joining techniques developed for less hostile environments do not work. Understanding fundamental issues in joining enables the development of new techniques to be able to utilize new materials. A previous DOE workshop defined fundamental and critical issues in ceramic joining and classified them into four general areas: joining techniques; joint failure; residual stress; and characterization and testing. The present international symposium is an effort to discuss some of these fundamental issues and to define areas for future research. Separate abstracts have been indexed into the energy database for articles from this symposium.

    A method of joining similar or dissimilar ceramic and ceramic composite materials, such as SiC continuous fiber ceramic composites, at relatively low joining temperatures uses a solventless, three component bonding agent effective to promote mechanical bond toughness and elevated temperature strength to operating temperatures of approximately 1200 degrees C. The bonding agent comprises a preceramic precursor, an aluminum bearing powder, such as aluminum alloy powder, and mixtures of aluminum metal or alloy powders with another powder, and and boron powder in selected proportions. The bonding agent is disposed as an interlayer between similar or dissimilar ceramic or cermaic composite materials to be joined and is heated in ambient air or inert atmosphere to a temperature not exceeding about 1200 degrees C. to form a strong and tough bond joint between the materials. The bond joint produced is characterized by a composite joint microstructure having relatively soft, compliant aluminum bearing particulate regions dispersed in a ceramic matrix.

    Bates, Carl H.; Couhig, John T.; Pelletier, Paul J.

    1990-05-01

    A method of joining two porous bodies of silicon carbide is disclosed. It entails utilizing an aqueous slip of a similar silicon carbide as was used to form the porous bodies, including the sintering aids, and a binder to initially join the porous bodies together. Then the composite structure is subjected to cold isostatic pressing to form a joint having good handling strength. Then the composite structure is subjected to pressureless sintering to form the final strong bond. Optionally, after the sintering the structure is subjected to hot isostatic pressing to further improve the joint and densify the structure. The result is a composite structure in which the joint is almost indistinguishable from the silicon carbide pieces which it joins.

    1982-01-01

    Blaugher reviews two recent joint development programs for superconductor joining. The force-cooled steel-enclosed westinghouse LCP Nb/sub 3/Sn conductor and the problem it presented of connecting lengths of full-size conductor and individual strands during wire manufacture were responsible for the first program, pursued both by Westinghouse and Airco, who focused on three main approaches: butt-resistance welding, lap joining, and cold welding. Results of the research into each of these approaches is given; butt-resistance welding was the method decided on. The second program was directed at the copper-stabilized Nb-Ti multifilamentary superconductor for the Westinghouse/EPRI 3000 MVA generator. Again, three main approaches were considered: butt-resistance, ultrasonic welding, and lap/mechanical joining. Experimentation with each approach led to the development of an ultrasonic welding method which offered high mechanical strength as well as acceptable electrical properties at low temperatures.

Clubbing was associated with lower presenting heart and respiratory rates and enlarged parotid glands. Total and CD4 + lymphocytes, CD4:CD8 ratio and LDH were lower in children with clubbing, but serum protein and gammaglobulin were higher. No differences in the prevalence or type of microbial pathogens were found between the two groups. Clubbing was associated with a radiological diagnosis of LIP. Children with clubbing had a lower in-hospital mortality rate than those without clubbing (6.7% vs 24.2%, p = 0.035). In geographical areas with high HIV seroprevalence rates, the presence of clubbing in a child hospitalized for respiratory disease should raise the suspicion of HIV infection. PMID:11284240

  4. Providing medical marijuana: the importance of cannabis clubs.

    PubMed

    Feldman, H W; Mandel, J

    1998-01-01

    In 1996, shortly after the San Francisco Cannabis Club was raided and (temporarily) closed by state authorities, the authors conducted an ethnographic study by interviewing selected former members to ascertain how they had benefited from the use of medical marijuana and how they had utilized the clubs. Interviews were augmented by participant observation techniques. Respondents reported highly positive health benefits from marijuana itself, and underscored even greater benefits from the social aspects of the clubs, which they described as providing important emotional supports. As such, cannabis clubs serve as crucial support mechanisms/groups for people with a wide variety of serious illnesses and conditions. The authors concluded that of the various methods so far proposed, the cannabis clubs afford the best therapeutic setting for providing medical cannabis and for offering a healing environment composed of like-minded, sympathetic friends.

    In a retrospective study of 399 patients with ulcerative colitis, 27 patients had colitic arthritis, 17 had ankylosing spondylitis, and 20 had clubbing of the fingers. Colitic arthritis and ankylosing spondylitis were not related to severity, extent of involvement, or duration of colitis. A significant association between colitic arthropathy and other complications of ulcerative colitis, such as pseudopolyposis, perianal disease, eye lesions, skin eruptions, aphthous ulceration, and liver disease has been demonstrated. The outcome of the first referred attack of colitis in the presence of colitic arthritis and ankylosing spondylitis remained uninfluenced. Clubbing of fingers was related to severity, extent of involvement, and length of the history of colitis. A significant association between clubbing of the fingers and carcinoma of the colon, pseudopolyposis, toxic dilatation, and arthropathy has been shown. The frequency of surgical intervention in patients with clubbing was higher but the overall mortality was not significantly different from the patients without clubbing. PMID:5473606

    CERN's communication goes beyond publishing scientific results. Education and outreach are equally important ways of communicating with the general public, and in particular with the young generation. Over the last decade, CERN has significantly increased its efforts to accommodate the very large interest of the general public (about 300,000 visit requests per year), by ramping up its capacity for guided tours from 25,000 to more than 100,000 visitors per year, by creating six new of state-of-the-art exhibitions on-site, by building and operating a modern physics laboratory for school teachers and students, and by showing several traveling exhibitions in about 10 countries per year. The offer for school teachers has also been expanded, to 35-40 weeks of teacher courses with more than 1000 participants from more than 50 countries per year. The talk will give an overview about these and related activities.

    The COMPASS experiment at the CERN SPS has a broad physics program focused on the study of the spin structure of the nucleon and on hadron spectroscopy. Key measurements for the spin program are the gluon contribution to the spin of the nucleon, flavor dependent quark spin distribution, and the measurement of the transverse spin structure function. The apparatus consists of a two-stage spectrometer designed for high data rates and equipped with high-resolution tracking, particle identification, electromagnetic and hadronic calorimetry. Data taking has started in 2002. Following the CERN SPS shut down in 2005, the experiment will resume data taking in 2006 and is planned to continue (at least) until 2010. Few hundreds of Terabytes of data are put on tape each year. Out of this large amount of data first important physics results have been obtained.

  11. Box Cello Middle School Science Clubs

    1998-10-01

    The Box Cello is a middle school science club which is attempting to (1) understand the cello and (2) design a low-cost starter instrument. We can support and justify this research by adding a third goal: (3) to help supply local science classes with equipment. My policy of spending one entire day each week away from the university, out in a local school is essential to this project. This schedule also permits me to conduct lessons on optics and music in the schools. And, it permits circulation of tools and equipment. A simple calculation demonstrates the great economy achieved by combining science clubs with academic year school visits. Consider the cost of letting 10,000 students in 10 middle schools each learn about and play with a pair of "upside-down" glasses for one hour. A visit to each school for three consecutive weeks would easily permit such a circulation if only 30 pairs were constructed. Assume rhetorically, that the construction of 30 pairs of glasses were to consume the entire estimated annual budget of $100,000. The cost per student would be only ten dollars! The visits, guest lectures, and equipment loans permit informal networking (including lunch) with math, science and music teachers in 10 schools.

    2011-10-01

    Recent research suggests that establishing water clubs in care homes can counteract the dangers of dehydration and enhance residents' health and well-being. This study provided an experimental test of this idea, and also explored the possibility that it is the social interaction that clubs provide which delivers health-related benefits. Consistent with this hypothesis, the study found no evidence that, on its own, increased focus on water consumption enhanced residents' health or well-being. However, residents who took part in water clubs showed improved levels of perceived social support, and those who participated in water and control clubs showed beneficial outcomes in terms of the number of General Practitioner calls they required. Consistent with a social identity approach to health and well-being, a mediation analysis also indicated that clubs achieve these positive outcomes by providing social support that helps to build a shared sense of social identity among residents.

The major role of a journal club is to introduce concepts of critical thinking and evaluation of research literature. This study describes how the understanding of papers presented in a surgical journal club improves by the use of a handout as an aid to revision, and reading skills of the participants are evaluated by a post-test. It shows how participation improves when a climate of mutual respect is created and when the subject under discussion answers questions related to real life needs and the new knowledge acquired has an immediate application.

  8. Joining of silicon nitrides using oxynitride glasses

    SciTech Connect

    O`Brien, M.H.

    1993-03-01

    This report presents a study on commercial silicon nitrides that were successfully joined using oxynitride glasses. Sintered silicon nitride was joined by either closed or glass-filled joints. Glass-filled joints were successfully used on hot-pressed silicon nitrides and were comparable in fast fracture strength to unjoined silicon nitrides up to approximately 1000C. Above that temperature, strengths decreased rapidly and glass flow failure began. The study observed that time-dependent failure currently limits the service temperatures of glass-filled joints. Creep failure occurred in excess of 1000C. Between 900 and 1000C, slow crack growth failure was observed. Cavitation (or viscous deformation) was the rate-controlling mechanism of slow crack growth.

    Iridium-coated rhenium (Ir/Re) provides thermal margin for high performance and long life radiation cooled rockets. Two issues that have arisen in the development of flight Ir/Re engines are the sparsity of rhenium (Re) mechanical property data (particularly at high temperatures) required for engineering design, and the inability to directly electron beam weld Re chambers to C103 nozzle skirts. To address these issues, a Re mechanical property database is being established and techniques for creating Re/C103 transition joints are being investigated. This paper discusses the tensile testing results of powder metallurgy Re samples at temperatures from 1370 to 2090 C. Also discussed is the evaluation of Re/C103 transition pieces joined by both, explosive and diffusion bonding. Finally, the evaluation of full size Re transition pieces, joined by inertia welding, as well as explosive and diffusion bonding, is detailed.

    Large-scale long-term projects such as the LHC require the ability to store, manage, organize and distribute large amounts of engineering information, covering a wide spectrum of fields. This information is a living material, evolving in time, following specific lifecycles. It has to reach the next generations of engineers so they understand how their predecessors designed, crafted, operated and maintained the most complex machines ever built. This is the role of CERN EDMS. The Engineering and Equipment Data Management Service has served the High Energy Physics Community for over 15 years. It is CERN's official PLM (Product Lifecycle Management), supporting engineering communities in their collaborations inside and outside the laboratory. EDMS is integrated with the CAD (Computer-aided Design) and CMMS (Computerized Maintenance Management) systems used at CERN providing tools for engineers who work in different domains and who are not PLM specialists. Over the years, human collaborations and machines grew in size and complexity. So did EDMS: it is currently home to more than 2 million files and documents, and has over 6 thousand active users. In April 2014 we released a new major version of EDMS, featuring a complete makeover of the web interface, improved responsiveness and enhanced functionality. Following the results of user surveys and building upon feedback received from key users group, we brought what we think is a system that is more attractive and makes it easy to perform complex tasks. In this paper we will describe the main functions and the architecture of EDMS. We will discuss the available integration options, which enable further evolution and automation of engineering data management. We will also present our plans for the future development of EDMS.

    A method for diffusion bonding ceramic layers such as boron carbide, zirconium carbide, or silicon carbide uses a defocused laser beam to heat and to join ceramics with the use of a thin metal foil insert. The metal foil preferably is rhenium, molybdenum or titanium. The rapid, intense heating of the ceramic/metal/ceramic sandwiches using the defocused laser beam results in diffusive conversion of the refractory metal foil into the ceramic and in turn creates a strong bond therein.

    Joining of structural ceramics is possible using high melting point metals such as Mo and Pt that are heated with a high energy electron beam, with the potential for high temperature joining. A 10 MeV electron beam can penetrate through 1 cm of ceramic, offering the possibility of buried interface joining. Because of transient heating and the lower heat capacity of the metal relative to the ceramic, a pulsed high power beam has the potential for melting the metal without decomposing or melting the ceramic. We have demonstrated the feasibility of the process with a series of 10 MeV, 1 kW electron beam experiments. Shear strengths up to 28 MPa have been measured. This strength is comparable to that reported in the literature for bonding silicon nitride to molybdenum with copper-silver-titanium braze, but weaker than that reported for Si{sub 3}N{sub 4}-Si{sub 3}N{sub 4} with gold-nickel braze. The bonding mechanism appears to be a thin silicide layer.

  17. SILICON CARBIDE JOINING. FINAL TOPICAL REPORT

    SciTech Connect

    1998-10-01

    Future energy systems will be required to fire lower-grade fuels and meet higher energy conversion efficiencies than today's systems. The steam cycle used at present is limited to a maximum temperature of 550 C because above that, the stainless steel tubes deform and corrode excessively. To boost efficiency significantly, much higher working fluid temperatures are required. Although high-temperature alloys will suffice for the construction of these components in the near term, the greatest efficiency increases can be reached only with the use of advanced structural ceramics such as silicon carbide (SiC). However, SiC does not melt, but instead sublimes at temperatures over 2000 C. Therefore, it is not possible to join pieces of it through welding, and most brazing compounds have much lower melting points, so the joints lose strength at temperatures much lower than the maximum use temperature of the SiC. Since larger objects such as heat exchangers cannot be easily created from smaller ceramic pieces, the size of the SiC structures that can presently be manufactured are limited by the size of the sintering furnaces (approximately 10 feet for sintered alpha SiC). In addition, repair of the objects will require the use of field-joining techniques. Some success has been had by causing silicon and carbon to react at 1400--1500 C to form SiC in a joint (Rabin, 1995), but these joints contain continuous channels of unreacted silicon, which cause the joints to corrode and creep excessively at temperatures below 1260 C (Breder and Parten, 1996). The objective of this work conducted at the Energy & Environmental Research Center (EERC) is to develop a patentable technique for joining large SiC structures in the field. The key to developing a successful technique will be the use of reactive joining compounds to lower the joining temperature without leaving continuous channels of unreacted compounds that can weaken the joint at temperatures below 1260 C or serve as conduits for

    CDC designed its Health Systems Integration Program to prepare leaders to function at the interface of public health and health care. Specific Health Systems Integration Program competencies in the areas of communication, analysis and assessment, and health systems were developed to nurture evidence-based decision-making and leadership skills crucial for future public health leaders. The program therefore designed an innovative journal club as part of its competency-based curriculum not only to meet the standard goals for a journal club-critical reading, interpretation, and acquiring content knowledge-but also to foster leadership development. This report describes the Health Systems Integration Program journal club format, its implementation, challenges, and key elements of success. Other programs using a journal club model as a learning format might consider using the Health Systems Integration Program's innovative approach that focuses on leadership development. PMID:25439249

    Cranio-osteoarthropathy, clinically classified as a variant of primary hypertrophic osteoarthropathy, is a very rare autosomal-recessive condition characterized by delayed closure of the cranial sutures and fontanels, digital clubbing, arthropathy, and periostosis. Recently, mutations in the gene HPGD, which encodes the NAD(+)-dependent 15-hydroxyprostaglandin dehydrogenase, were reported in four families affected with primary hypertrophic osteoarthropathy and one family with autosomal-recessive isolated nail clubbing. We report the clinical and molecular findings in four patients from two families affected with cranio-osteoarthropathy and one family with isolated, autosomal dominant digital clubbing. Genome-wide homozygosity mapping identified a locus for cranio-osteoarthropathy harboring the HPGD gene in one affected family. We detected two novel homozygous mutations in HPGD in these families: a missense mutation affecting the NAD(+) binding motif and a frameshift mutation. The clinical presentation in our patients was variable. Digital clubbing and hyperhidrosis were present in all cases. Delayed closure of the cranial sutures and fontanels, periostosis, and arthropathy were not consistent clinical features. No HPGD mutation was detected in a familial case of autosomal dominant isolated digital clubbing. The failure to identify any mutation in a family with an autosomal dominant type of isolated digital clubbing suggests that HPGD is not the major gene for this condition. PMID:19568269

    2014-06-01

    In the last three years the CernVM File System has transformed the distribution of experiment software to WLCG sites. CernVM-FS removes the need for local installations jobs and performant network fileservers at sites and it often improves performance at the same time. Now established and proven to work at scale, CernVM-FS is beginning to perform a similar role for non-LHC computing. The deployment of CernVM-FS service at RAL Tier-1 is presented, as well as the proposed development of a network of Stratum-0 and Stratum-1 replicas somewhat modelled upon the infrastructure developed to support the WLCG computing. A case study of one non-LHC Virtual Organization is also included, describing their use of the CernVM-FS Stratum-0 service, along with a web interface intended to be used as a tool to upload software at Stratum-0 sites.

  13. Who will volunteer? Analysing individual and structural factors of volunteering in Swiss sports clubs.

    2013-01-01

    This article analyses the conditions influencing volunteering in sports clubs. It focuses not only on individual characteristics of volunteers but also on the corresponding structural conditions of sports clubs. It proposes a model of voluntary work in sports clubs based on economic behaviour theory. The influences of both the individual and context levels on the decision to engage in voluntary work are estimated in different multilevel models. Results of these multilevel analyses indicate that volunteering is not just an outcome of individual characteristics such as lower workloads, higher income, children belonging to the sports club, longer club memberships, or a strong commitment to the club. It is also influenced by club-specific structural conditions; volunteering is more probable in rural sports clubs whereas growth-oriented goals in clubs have a destabilising effect.

    1962-02-13

    A method is described for joining a refractory metal carbide such as UC or ZrC to a refractory metal base such as Ta or Nb. The method comprises carburizing the surface of the metal base and then sintering the base and carbide at temperatures of about 2000 deg C in a non-oxidizing atmosphere, the base and carbide being held in contact during the sintering step. To reduce the sintering temperature and time, a sintering aid such as iron, nickel, or cobait is added to the carbide, not to exceed 5 wt%. (AEC)

    In this article we present a theoretical construction of spacetimes with a thin shell that joins two different local cosmic string geometries. We study two types of global manifolds, one representing spacetimes with a thin shell surrounding a cosmic string or an empty region with Minkowski metric, and the other corresponding to wormholes which are not symmetric across the throat located at the shell. We analyze the stability of the static configurations under perturbations preserving the cylindrical symmetry. For both types of geometries we find that the static configurations can be stable for suitable values of the parameters.

    Friction stir welding and ultrasonic welding techniques were applied to join automotive magnesium alloys to steel sheet. The effect of tooling and process parameters on the post-weld microstructure, texture and mechanical properties was investigated. Static and dynamic loading were utilized to investigate the joint strength of both cast and wrought magnesium alloys including their susceptibility and degradation under corrosive media. The conditions required to produce joint strengths in excess of 75% of the base metal strength were determined, and the effects of surface coatings, tooling and weld parameters on weld properties are presented.

    The authors study a new solid-state spot joining process, friction bit joining (FBJ), which relies on the use of a consumable joining bit. It has been reported that FBJ is feasible for the joining of steel/steel and aluminum/steel, but the metallurgical characteristics of the joint for enhancement of the properties and reliability remain unclear. Therefore, this study produced friction bit joints in DP980 steel and then examined the microstructures in the joint precisely. In this article, the microstructure distribution associated with hardness in the friction-bit-joined DP980 steel and the microstructural evolution during FBJ are reported.

  18. Long Term Stability of Laser Joined Plastic Metal Parts

    NASA Astrophysics Data System (ADS)

    Roesner, A.; Olowinsky, A.; Gillner, A.

    To join plastic to metal a laser based two-step laser process is described. The first process step is the laser micro structuring of the metal surface to create microstructures with undercut grooves. The subsequent transmission joining process allows a selective heating of arbitrary component geometries and the local control of the joining temperature. Both parts are brought into direct contact prior to welding. The plastic part is melted and expands into the microstructures through the external clamping pressure. The joining results due to micro cramping after setting. The long term stability of the joining is described.

    After School Astronomy clubs are an important method of exposing students to astronomy at the critical middle school age when sparking an interest can inspire a lifelong career or hobby. We know that teachers complain that they can spend little time on astronomy in the classroom since they must teach to the test and the curriculum requirements do not have very extensive astronomy coverage. We also know that space is a very popular subject with students that can motivate them to join an after school club. One of the problems with after school astronomy clubs is that they don't often have a chance to observe the night sky. We propose to train club mentors on how to do daytime solar observing so students fulfill the IYA goal of looking through a telescope. We propose to provide a half day workshop for elementary and middle school teachers on starting and maintaining After School Astronomy clubs with special emphasis on observing the Sun not only in the visible spectrum but with radio waves and other parts of the spectrum as well. We will use NASA-oriented or NASA-funded educational materials and websites to bring a variety of ideas to the mentors and a broad knowledge of astronomy to the students. Attendees will be given an overview of the science of the Sun and how it can affect us on the Earth. They will be shown the dynamic nature of the Sun and what to look for to track the events happening there. The educators will be shown simple approaches to directly observing the Sun such as pinhole cameras, use of projection techniques with telescopes or binoculars, etc. They will be acquainted with sunspotter scopes and the advantages and disadvantages (such as expense) they pose for getting students involved. We will also point out the possibilities of using regular telescopes with solar filters and the specialized solar viewing telescopes such as the Coronado. Once the educators are comfortable with the simple approaches to viewing the Sun we will expose them to advanced

    In this work we analyse the biggest particle accelerator in the world: the LHC (Large Hadron Collider). The ring shaped tunnel is 27 km long and it is buried over 110 meters underground, straddling the border betwen France and Switzerland at the CERN laboratory near Geneva. Its mission is to recreate the conditions that existed shortly after the Big-Bang and to look for the hypothesised Higgs particle. The LHC will accelerate protons near the speed of the light and collide them head on at an energy of to 14 TeV (1 TeV = 10(12) eV). Keeping such high energy in the proton beams requires enormous magnetic fields which are generated by superconducting electromagnets chilled to less than two degrees above absolute zero. It is expected that LHC will be inaugurated in summer 2007.

    2013-01-01

    The join or correlated filtering of sensor readings is one of the fundamental query operations in wireless sensor networks (WSNs). Although the join in centralized or distributed databases is a well-researched problem, join processing in WSNs has quite different characteristics and is much more difficult to perform due to the lack of statistics on sensor readings and the resource constraints of sensor nodes. Since data transmission is orders of magnitude more costly than processing at a sensor node, in-network processing of joins is essential. In this paper, the state-of-the-art techniques for join implementation in WSNs are surveyed. The requirements and challenges, join types, and components of join implementation are described. The open issues for further research are identified. PMID:23478603

  4. Joining of Tungsten Armor Using Functional Gradients

    The joining of low thermal expansion armor materials such as tungsten to high thermal expansion heat sink materials has been a major problem in plasma facing component (PFC) development. Conventional planar bonding techniques have been unable to withstand the high thermal induced stresses resulting from fabrication and high heat flux testing. During this investigation, innovative functional gradient joints produced using vacuum plasma spray forming techniques have been developed for joining tungsten armor to copper alloy heat sinks. A model was developed to select the optimum gradient architecture. Based on the modeling effort, a 2mm copper rich gradient was selected. Vacuum plasma pray parameters and procedures were then developed to produce the functional gradient joint. Using these techniques, dual cooling channel, medium scale mockups (32mm wide x 400mm length) were produced with vacuum plasma spray formed tungsten armor. The thickness of the tungsten armor was up to 5mm thick. No evidence of debonding at the interface between the heat sink and the vacuum plasma sprayed material was observed.

    1997-01-01

    A method for joining two or more items having surfaces of thermoplastic material includes the steps of depositing an electrically-conductive material upon the thermoplastic surface of at least one of the items, and then placing the other of the two items adjacent the one item so that the deposited material is in intimate contact with the surfaces of both the one and the other items. The deposited material and the thermoplastic surfaces contacted thereby are then exposed to microwave radiation so that the thermoplastic surfaces in contact with the deposited material melt, and then pressure is applied to the two items so that the melted thermoplastic surfaces fuse to one another. Upon discontinuance of the exposure to the microwave energy, and after permitting the thermoplastic surfaces to cool from the melted condition, the two items are joined together by the fused thermoplastic surfaces. The deposited material has a thickness which is preferably no greater than a skin depth, .delta..sub.s, which is related to the frequency of the microwave radiation and characteristics of the deposited material in accordance with an equation.

    1996-01-01

    OBJECTIVE: To determine the frequency, nature, circumstances, and outcome of schoolboy rugby injuries and to compare these injuries with those occurring in senior rugby clubs. METHODS: The study was a prospective cohort study, conducted on 1705 (98%) of 1736 eligible players from nine Edinburgh schools and 1169 (96%) of 1216 eligible players from all 26 senior Scottish Rugby Union clubs (South District) who provided personal details before the 1993-1994 rugby season. Adult linkpersons were appointed to notify the circumstances of all injury episodes occurring in matches or in rugby related training. RESULTS: 154 school players (9%) experienced 210 separate injuries in 186 injury episodes, 80% of which arose in matches. The prevalence rate of schoolboy match injuries was 86.8 (95% confidence interval 73.4 to 100.2) per 1000 player-seasons. Senior club match injury prevalence was much higher at 367.0 (339.4 to 394.6) per 1000 player-seasons. Club players had a higher rate of match injury than school-boys for all injury types. One third of schoolboy match injury episodes occurred in September and the majority of match injury episodes were associated with tackling (40%) or with being tackled (24%). Nine per cent of schoolboy match injury episodes were classified as severe, compared to 13% for clubs. Sixteen per cent (n = 23) of all schoolboy match injury episodes resulted in missed school attendance compared with 27% (n = 117) of all senior club match injury episodes which involved loss of employment or education. CONCLUSIONS: Schoolboy rugby is much safer than senior club rugby and the outcome of injuries that do occur is less disruptive. The relatively high rate of match injury in September migh be reduced by a more intensive period of preseason training. PMID:8889113

    The recent paradigm shift toward cloud computing in IT, and general interest in "Big Data" in particular, have demonstrated that the computing requirements of HEP are no longer globally unique. Indeed, the CERN IT department and LHC experiments have already made significant R&D investments in delivering and exploiting cloud computing resources. While a number of technical evaluations of interesting commercial offerings from global IT enterprises have been performed by various physics labs, further technical, security, sociological, and legal issues need to be address before their large-scale adoption by the research community can be envisaged. Helix Nebula - the Science Cloud is an initiative that explores these questions by joining the forces of three European research institutes (CERN, ESA and EMBL) with leading European commercial IT enterprises. The goals of Helix Nebula are to establish a cloud platform federating multiple commercial cloud providers, along with new business models, which can sustain the cloud marketplace for years to come. This contribution will summarize the participation of CERN in Helix Nebula. We will explain CERN's flagship use-case and the model used to integrate several cloud providers with an LHC experiment's workload management system. During the first proof of concept, this project contributed over 40.000 CPU-days of Monte Carlo production throughput to the ATLAS experiment with marginal manpower required. CERN's experience, together with that of ESA and EMBL, is providing a great insight into the cloud computing industry and highlighted several challenges that are being tackled in order to ease the export of the scientific workloads to the cloud environments.

  8. EFQPSK Versus CERN: A Comparative Study

    2001-01-01

    This report presents a comparative study on Enhanced Feher's Quadrature Phase Shift Keying (EFQPSK) and Constrained Envelope Root Nyquist (CERN) techniques. These two techniques have been developed in recent times to provide high spectral and power efficiencies under nonlinear amplifier environment. The purpose of this study is to gain insights into these techniques and to help system planners and designers with an appropriate set of guidelines for using these techniques. The comparative study presented in this report relies on effective simulation models and procedures. Therefore, a significant part of this report is devoted to understanding the mathematical and simulation models of the techniques and their set-up procedures. In particular, mathematical models of EFQPSK and CERN, effects of the sampling rate in discrete time signal representation, and modeling of nonlinear amplifiers and predistorters have been considered in detail. The results of this study show that both EFQPSK and CERN signals provide spectrally efficient communications compared to filtered conventional linear modulation techniques when a nonlinear power amplifier is used. However, there are important differences. The spectral efficiency of CERN signals, with a small amount of input backoff, is significantly better than that of EFQPSK signals if the nonlinear amplifier is an ideal clipper. However, to achieve such spectral efficiencies with a practical nonlinear amplifier, CERN processing requires a predistorter which effectively translates the amplifier's characteristics close to those of an ideal clipper. Thus, the spectral performance of CERN signals strongly depends on the predistorter. EFQPSK signals, on the other hand, do not need such predistorters since their spectra are almost unaffected by the nonlinear amplifier, Ibis report discusses several receiver structures for EFQPSK signals. It is observed that optimal receiver structures can be realized for both coded and uncoded EFQPSK

  9. Estimating Impact Forces of Tail Club Strikes by Ankylosaurid Dinosaurs

    PubMed Central

    Arbour, Victoria Megan

    2009-01-01

    Background It has been assumed that the unusual tail club of ankylosaurid dinosaurs was used actively as a weapon, but the biological feasibility of this behaviour has not been examined in detail. Ankylosaurid tail clubs are composed of interlocking vertebrae, which form the handle, and large terminal osteoderms, which form the knob. Methodology/Principal Findings Computed tomographic (CT) scans of several ankylosaurid tail clubs referred to Dyoplosaurus and Euoplocephalus, combined with measurements of free caudal vertebrae, provide information used to estimate the impact force of tail clubs of various sizes. Ankylosaurid tails are modeled as a series of segments for which mass, muscle cross-sectional area, torque, and angular acceleration are calculated. Free caudal vertebrae segments had limited vertical flexibility, but the tail could have swung through approximately 100° laterally. Muscle scars on the pelvis record the presence of a large M. longissimus caudae, and ossified tendons alongside the handle represent M. spinalis. CT scans showed that knob osteoderms were predominantly cancellous, which would have lowered the rotational inertia of the tail club and made it easier to wield as a weapon. Conclusions/Significance Large knobs could generate sufficient force to break bone during impacts, but average and small knobs could not. Tail swinging behaviour is feasible in ankylosaurids, but it remains unknown whether the tail was used for interspecific defense, intraspecific combat, or both. PMID:19707581

    2014-01-01

    During November 1933 the trial of three men accused of 'living off the earnings of prostitution' captivated the news reading public of Edinburgh. This article uses the detailed trial transcription and newspaper coverage of the Kosmo Club trial to examine the role that dance clubs played within a larger network of clandestine prostitution and the implications this had for the women who worked in these clubs as 'dance partners'. The case study focuses on a key moment in the history of prostitution, one that has not yet received sufficient historical attention, a moment when new technologies, such as the telephone and the motorcar, first began to dramatically alter the landscape of prostitution. Furthermore, the trial offers a rare glimpse of dance partners' experiences, both the dangers they faced and the many ways in which they attempted to resist those who sought to control and exploit them.

    Recognizing the ongoing need for continuing education for school nurses, the authors discuss the use of school nurse book clubs as an innovative lifelong-learning strategy. Current research supports the use of literature in nursing education. This article discusses the benefits of book club participation for school nurses and includes suggested fiction and nonfiction books that can be used to enhance nursing knowledge and practice. Through reading and discussion, school nurses can increase their knowledge of nursing history and current health care issues, thus becoming better prepared to address challenging issues that arise in practice. In addition, the use of literature as a learning strategy allows school nurses to broaden their understanding of unique cultural factors that influence the health beliefs and practices of students and their families. Book club participation can also assist school nurses in honing leadership and communication skills and becoming energized to become better advocates for children and families. PMID:18363439

    Medical media is changing along with the rest of the media landscape. One of the more interesting ways that medical media is evolving is the increased role of social media in medical media's creation, curation and distribution. Twitter, a microblogging site, has become a central hub for finding, vetting, and spreading this content among doctors. We have created a Twitter journal club for nephrology that primarily provides post-publication peer review of high impact nephrology articles, but additionally helps Twitter users build a network of engaged people with interests in academic nephrology. By following participants in the nephrology journal club, users are able to stock their personal learning network. In this essay we discuss the history of medical media, the role of Twitter in the current states of media and summarize our initial experience with a Twitter journal club.

    Recognizing the ongoing need for continuing education for school nurses, the authors discuss the use of school nurse book clubs as an innovative lifelong-learning strategy. Current research supports the use of literature in nursing education. This article discusses the benefits of book club participation for school nurses and includes suggested fiction and nonfiction books that can be used to enhance nursing knowledge and practice. Through reading and discussion, school nurses can increase their knowledge of nursing history and current health care issues, thus becoming better prepared to address challenging issues that arise in practice. In addition, the use of literature as a learning strategy allows school nurses to broaden their understanding of unique cultural factors that influence the health beliefs and practices of students and their families. Book club participation can also assist school nurses in honing leadership and communication skills and becoming energized to become better advocates for children and families.

  17. The Kosmo Club case: clandestine prostitution during the interwar period.

    2014-01-01

    During November 1933 the trial of three men accused of 'living off the earnings of prostitution' captivated the news reading public of Edinburgh. This article uses the detailed trial transcription and newspaper coverage of the Kosmo Club trial to examine the role that dance clubs played within a larger network of clandestine prostitution and the implications this had for the women who worked in these clubs as 'dance partners'. The case study focuses on a key moment in the history of prostitution, one that has not yet received sufficient historical attention, a moment when new technologies, such as the telephone and the motorcar, first began to dramatically alter the landscape of prostitution. Furthermore, the trial offers a rare glimpse of dance partners' experiences, both the dangers they faced and the many ways in which they attempted to resist those who sought to control and exploit them.

  18. Inventories of psychological skills for athletic clubs and school life.

    Some students who participate in athletic activities transfer the skills acquired in a sports context into other areas of life, while others do not. To identify the specific skills that are transferred or not from sports to the school environment, two inventories were developed: the "Psychological Skills Inventory for Athletic Clubs" and the "Psychological Skills Inventory for School Life." These inventories enable a comparison of skills in a sport context with skills in a school context. In the first stage, 307 Japanese first-year university students who had participated in high school athletic clubs volunteered to take part in a survey to develop these inventories. Analyses indicated that both inventories comprised identical subscales of intrapersonal and interpersonal skills. In the second stage, the reliability and validity of these inventories was confirmed for 531 Japanese high school students who were members of athletic clubs for sports such as soccer and baseball.

    Medical media is changing along with the rest of the media landscape. One of the more interesting ways that medical media is evolving is the increased role of social media in medical media's creation, curation and distribution. Twitter, a microblogging site, has become a central hub for finding, vetting, and spreading this content among doctors. We have created a Twitter journal club for nephrology that primarily provides post-publication peer review of high impact nephrology articles, but additionally helps Twitter users build a network of engaged people with interests in academic nephrology. By following participants in the nephrology journal club, users are able to stock their personal learning network. In this essay we discuss the history of medical media, the role of Twitter in the current states of media and summarize our initial experience with a Twitter journal club. PMID:25906989

  20. The new CERN Controls Middleware

    NASA Astrophysics Data System (ADS)

    Dworak, A.; Ehm, F.; Charrue, P.; Sliwinski, W.

    2012-12-01

    The Controls Middleware (CMW) project was launched over ten years ago. Its main goal was to unify middleware solutions used to operate the CERN accelerator complex. A key part of the project, the equipment access library RDA, was based on CORBA, an unquestionable middleware standard at the time. RDA became an operational and critical part of the infrastructure, yet the demanding run-time environment revealed shortcomings of the system. Accumulation of fixes and workarounds led to unnecessary complexity. RDA became difficult to maintain and to extend. CORBA proved to be rather a cumbersome product than a panacea. Fortunately, many new transport frameworks appeared since then. They boasted a better design and supported concepts that made them easier to use. Willing to profit from the coming long LHC shutdown which will make it possible to update the operational software, the CMW team reviewed user requirements and in their terms investigated eventual CORBA substitutes. Evaluation of several market recognized products helped to identify the most-suitable middleware solution: ZeroMQ. This article presents the results of the evaluation process, the proposed design and functionality of the new system as well as the plan of its integration with the currently deployed system.

    2007-03-01

    Hadron production measurements for neutrino experiments is a well established field at CERN since the '70s. Precise prediction of atmospheric neutrino fluxes, characterization of accelerator neutrino beams, quantification of pion production and capture for neutrino factory designs, all of these would profit from hadron production measurements. In recent years, interest in such studies was revived and new generation of low-energy (from 3 to 400 GeV) hadron production experiments were built or proposed. Such experiments all share a basic design, consisting in the presence of open-geometry spectrometers, as close as possible to full angular coverage, and aiming at full particle identification. New results are now provided by Harp in the very low energy range (3 to 15 GeV/c) and by NA49 at 158 GeV/c. In the next years NA49- future will explore the medium energy range (30 to 400 GeV/c) and at LHC energies for the first time thanks to the TOTEM experiment, it will be possible to measure with unprecedented precision the total cross section beyond 1 TeV/c.

    2016-04-01

    Searches for new physics with accelerators are being performed at the LHC, looking for high massive particles coupled to matter with ordinary strength. A new experimental facility meant to search for very weakly coupled particles in the few GeV mass domain has been recently proposed. The existence of such particles, foreseen in different theoretical models beyond the Standard Model, is largely unexplored from the experimental point of view. A beam dump facility, built at CERN in the north area, using 400 GeV protons is a copious factory of charmed hadrons and could be used to probe the existence of such particles. The beam dump is also an ideal source of tau neutrinos, the less known particle in the Standard Model. In particular, tau anti-neutrinos have not been directly observed so far. We report the physics potential of such an experiment and outline the performances of a detector operating at the same facility for the search for the τ → μμμ decay.

    2015-01-01

    Objective The current study examines the variation in alcohol use among nightclub patrons under three transportation conditions: those who departed from a club using modes of transportation other than cars or motorcycles (e.g., pedestrians, bicyclists, subway riders); those who were passengers of drivers (auto/taxi passenger patrons); and those who drove from the club (driving patrons). We seek to determine whether patrons' choice for how to leave the club contributes to their risk, as assessed by blood alcohol concentrations (BAC), after controlling for other factors that may contribute to their BAC including demographic characteristics and social drinking group influences. Methods Data were collected from social drinking groups as they entered and exited clubs for 71 different evenings at ten clubs from 2010 through 2012. Using portal methodology, a research site was established proximal to club entrances. Each individual participant provided data on themselves and others in their group. The present analyses are based upon 1833 individuals who completed both entrance and exit data. Our outcome variable is blood alcohol content (BAC) based upon breath tests attained from patrons at entrance and exit from the club. Independent variables include method of transportation, social group characteristics, drug use, and personal characteristics. We use step-wise multiple regressions to predict entrance BAC, change in BAC from entrance to exit, and exit BAC: first entering individual demographic characteristics, then entering group characteristics, then drug use, and finally entering method of transportation (two dummy coded variables such that drivers are the referent category). Results In sum, in all three of our analyses, only three variables are consistently predictive of BAC: presence of a group member who is frequently drunk and non-driving modes of transportation, either being the passenger or taking alternate methods of transportation. In particular, taking an

    Book clubs and discussion groups provide opportunities for hospital librarians to reach out to staff from all areas of their facilities while introducing them to literature reflecting participants' personal and professional interests. Librarians presenting these case studies have coordinated local book clubs where topics ranged from titles about the nature of healing, to leadership development, and patient-centered care. Some also included contemporary novels of interest to participants. No matter the setting or scope of material discussed, each group has provided unique networking opportunities for staff to meet others working in various departments of their facilities.

  7. A NEW APPROACH TO JOINING SIC/SIC COMPOSITES

    SciTech Connect

    Henager, Charles H.

    2004-06-30

    A new approach to joining SiC-based ceramics is described and evaluated for Fusion Energy systems. The joining method is based on pre-ceramic polymers filled with reactive and inert filler powders and is similar to other approaches that use such materials. This approach differs in the particular polymer system and in the details of the processing. A principal advantage of this approach relative to other, similar approaches is that the polymer system is easily handled in ambient air and can be processed in air. This makes the joining process simple and field repairable. The joining compound is a liquid that can be painted, sprayed, or applied by dip coating.

    2015-04-01

    This paper discusses re-emergence of Korean medicine(s) in the global context with a focus on a natural drug JOINS, a highly contentious drug regarding its legal status. By following through its life world, the paper contends that the drug is the embodiment of the postcolonial anxiety that crosses the intersections between the aspiring nation and globalizing strategies of the bio-pharmaceutical industry. JOINS is a natural drug prescribed to alleviate the symptoms of degenerative arthritis. SK Chemicals, Ltd., a giant domestic pharmaceutical company developed the drug by utilizing the knowledge of traditional pharmacopeia and put it on the market in 2001. In the domestic market, the drug is treated as a prescription drug, implying that Western medicine-trained doctors (as opposed to Korean medicine doctors) are entitled to prescribe drugs. It also indicates that the drug has undergone a series of lab tests such as toxicity, efficacy, and clinical trials in compliance with regulatory guidelines. However, the domestic standards are not rigorous enough to satisfy international standards, so that it is exported as a nutritional supplement abroad. The government, the pharmaceutical industry, and the Western medicine profession are happy with how the drug stands domestically and internationally. Rather, it is Korean doctors who try to disrupt the status quo and reclaim their rights to traditional knowledge, who have been alienated from the pharmaceuticalization of traditional knowledge. Thus, the JOINS tablet embodies the complex web of modern Korean society, professional interests, the pharmaceutical industry, and globalization. PMID:25641583

The computer simulation studied the interaction of population growth, food supply, inductrial production, resource use, and pollution under varying conditions. It concluded that our industrial system is headed for too many people in relation to food and living space, too much production in relation to natural resources, and for too much pollution. This will affect all countries. The traditional economists say the continued growth of the gross national product is the only way to ensure better living conditions while the ecologists point out that quality of life is being destroyed. The author cites arguments both for and against the quality-of-life view. The problem is that continued industrial growth creates wants as well as satisfying them and leads to waste as well as needful consumption. John Stuart Mill stated 100 years ago that the world could not support continued technological expansion and society must reach an equilibrium. 8 steps must be taken if the planet is to reach such an equilibrium, which is essential to the survival of all: 1) a zero rate of population growth, although there may be variations between countries with some over and some under; 2) a zero rate of industrial output with overall new investment equal to overall rate of industrial depreciation; 3) a policy of recycling and conserving material resources; 4) an adequate budget of food, shelter, clothing, health services, and education for every human being (a budget which does not allow for autos and air conditioning); 5) a sharp decline in consumption of material goods in affluent societies with a corresponding shift to more services and an increase in material goods for low energy societies

  7. Sexy ladies sexing ladies: women as consumers in strip clubs.

    Wosick-Correa, Kassia R; Joseph, Lauren J

    2008-01-01

    Recent shifts in the consumer base of the sex industry have involved greater female attendance in strip clubs. This article examines how strip clubs and dancers incorporate female patrons into a sexualized space traditionally designed for men by identifying three interactional processes: passing over, sidestaging, and tailoring. We suggest dancers pass over women because they perceive female patron behavior to include resistance to "buying the game" and spending patterns that diverge from male customers. Drawing on Goffman's dramaturgical analysis, we suggest the dynamic relationship between dancer and female patron involves what we term sidestaging, which refers to both dancers' disclosure and how the club's spatial organization inhibits the construction of women as customers through sharing gendered spaces, such as the bathroom. We argue that when a dancer tailors her lap dance for a female patron, she succeeds in acknowledging the female customer's sexual subjectivity and potential same-sex desires by providing an individualized avenue for exploring an erotic experience. Finally, we discuss data implications for understanding how same-sex desire and sexual identity operate in an environment that eroticizes the female form, and how the strip club becomes a potential space for engaging in same-sex eroticism that includes elements of play.

  10. The Hip-Hop club scene: Gender, grinding and sex.

    PubMed

    Muñoz-Laboy, Miguel; Weinstein, Hannah; Parker, Richard

    2007-01-01

    Hip-Hop culture is a key social medium through which many young men and women from communities of colour in the USA construct their gender. In this study, we focused on the Hip-Hop club scene in New York City with the intention of unpacking narratives of gender dynamics from the perspective of young men and women, and how these relate to their sexual experiences. We conducted a three-year ethnographic study that included ethnographic observations of Hip-Hop clubs and their social scene, and in-depth interviews with young men and young women aged 15-21. This paper describes how young people negotiate gender relations on the dance floor of Hip-Hop clubs. The Hip-Hop club scene represents a context or setting where young men's masculinities are contested by the social environment, where women challenge hypermasculine privilege and where young people can set the stage for what happens next in their sexual and emotional interactions. Hip-Hop culture therefore provides a window into the gender and sexual scripts of many urban minority youth. A fuller understanding of these patterns can offer key insights into the social construction of sexual risk, as well as the possibilities for sexual health promotion, among young people in urban minority populations.

    2015-06-01

    Though an adequate understanding of content is a natural prerequisite of teaching (Carlsen in Journal of Research in Science Teaching 30:471-481, 1993), teachers also need to be able to interpret content in ways that facilitate student learning. How to best support novice teachers in developing and refining their content knowledge for teaching is a crucial and ongoing question for preservice teacher educators. Recently, video clubs are being explored as potential contexts for teacher learning (Barnhart & van Es in Teaching and Teacher Education 45:83-93, 2015; Sherin & Han in Teaching and Teacher Education 20:163-183, 2004). We hypothesized that pairing video clubs with student teaching experiences would provide a forum for preservice teachers to discuss issues relevant to their professional trajectory through exposure to models of peer teaching and opportunities to reflect on practice. In this study, we explored how secondary science preservice teachers used video club to restructure their overall science knowledge into science knowledge for teaching. Our findings suggest that video clubs allowed preservice teachers to access and leverage student thinking and instructional resources to deepen their understanding of science content and trajectories for science learning.

    2001-01-01

    An investigation was made as to whether studies have found journal clubs for physicians in training to be effective for improving patient. care, teaching critical appraisal skills, improving reading habits, increasing knowledge of clinical epidemiology and biostatistics, and increasing the use of medical literature in clinical practice. A literature search was undertaken using 10 databases and retrieval systems and hand searches of journals, conference proceedings and personal files. The rigor of studies meeting the inclusion criteria was analyzed using a protocol based on methods established by the Cochrane Collaboration. One randomized controlled trial found an improvement in knowledge of clinical epidemiology and biostaristics, reading habits, and the use of medical literature in practice, but no improvement in critical appraisal skills. Six less methodologically rigorous studies found possible improvement in critical appraisal skills. It is concluded that journal clubs may improve knowledge of clinical epidemiology and biostatistics, reading habits, and the use of medical literature in practice. A multi-center, randomized controlled trial of journal clubs is needed to assess whether journal clubs improve critical appraisal skills.

    2010-10-01

    After School Astronomy clubs are unique in focusing on children in the K-12 grades as opposed to the numerous Amateur Astronomy Clubs within the US and abroad whose membership is largely adult focused. Over the last 12 years, we have identified over 100 clubs that were previously running in isolation, provided them with science and education resources and a means to communicate, created an online community of after School Astronomy Clubs, and facilitated the development of new clubs. Over this time, our model for developing and running these clubs has changed as we gained experience with various target populations, educational settings, and external partners and as best practices have emerged regarding engagement, impact, pedagogy, and sustainability. This talk will highlight these experiences and practices and discuss implications for future development of the After School Astronomy Club program.

    1998-01-01

    Joining is recognized as one of the enabling technologies for the application of silicon carbide-based ceramic and composite components in a number of demanding and high temperature applications in aerospace and ground-based systems. An affordable, robust ceramic joining technology (ARCJoinT) for joining of silicon carbide-based ceramics and fiber reinforced composites has been developed. This technique is capable of producing joints with tailorable thickness and composition. A wide variety of silicon carbide-based ceramics and composites, in different shapes and sizes, have been joined using this technique. These joints maintain their mechanical strength up to 1350 C in air. This technology is suitable for the joining of large and complex shaped ceramic and composite components and with certain modifications, can be applied to repair ceramic components damaged in service.

    Objectives To assess whether a journal club model could improve comprehension and written and spoken medical English in a population of Chinese medical professionals. Setting and participants The study population consisted of 52 medical professionals who were residents or postgraduate master or PhD students in the Department of Obstetrics and Gynecology, Heilongjiang University of Chinese Medicine, China. Intervention After a three-part baseline examination to assess medical English comprehension, participants were randomised to either (1) an intensive journal club treatment arm or (2) a self-study group. At the conclusion of the 8-week intervention participants (n=52) were re-tested with new questions. Outcome measures The primary outcome was the change in score on a multiple choice examination. Secondary outcomes included change in scores on written and oral examinations which were modelled on the Test of English as a Foreign Language (TOEFL). Results Both groups had improved scores on the multiple choice examination without a statistically significant difference between them (90% power). However, there was a statistically significant difference between the groups in mean improvement in scores for both written (95% CI 1.1 to 5.0; p=0.003) and spoken English (95% CI 0.06 to 3.7; p=0.04) favouring the journal club intervention. Conclusions Interacting with colleagues and an English-speaking facilitator in a journal club improved both written and spoken medical English in Chinese medical professionals. Journal clubs may be suitable for use as a self-sustainable teaching model to improve fluency in medical English in foreign medical professionals. Trial registration number NCT01844609.

    This qualitative study explored how in a 7-month-long journal club pre- and inservice science teachers engaged with education research literature relevant to their practice to reduce the theory-practice gap. In the journal club they had the opportunity to critique and analyze peer-reviewed science education articles in the context of their classroom practice. Data sources included audio recordings of the meetings; semi-structured pre- and post-interviews of the teachers; focus groups; and artifacts (e.g., journal articles, reflective paper, email exchanges, and researcher's field notes). Data were analyzed using the techniques of grounded theory (Corbin & Strauss in Basics of qualitative research, 3rd ed. Sage, Thousand Oaks, 2008). In addition we used some preconceived categories that we created from existing literature on journal clubs and communities of practice (Newswander & Borrego in European Journal of Engineering Education 34(6): 561-571, 2009; Wenger in Communities of practice: learning, meaning, and identity. Cambridge University Press, Cambridge, 1998) and from our previous research (Tallman & Feldman, 2012). We found that the journal club incorporated the three characteristics of a community of practice (Wenger in Communities of practice: learning, meaning, and identity. Cambridge University Press, Cambridge, 1998) into its functioning (mutual engagement, joint enterprise, and shared repertoire). The teachers mutually engaged around the joint enterprise of reading, critiquing, and understanding the research studies with the goal of improving practice. The teachers also asked each other analytical questions, which became a shared repertoire of the journal club. They reflected on their practice by presenting, reading, and discussing the articles, which helped them to determine whether and how the findings from the articles could be incorporated into their teaching practice. In doing so, they learned the skills needed to critique the research literature in

    To examine the social drinking group's influence on the individual's experiences of physical or sexual aggression at clubs, data were collected from 368 groups (N=986 individuals). Both group and individual level indicators were examined for impact on self-reports of physical and sexual aggression experiences while at the club. Recent aggressive experiences and perpetration, concerns for group safety, one's own plans and assessment of other group members' plans to drink to the point of intoxication, and personal characteristics were examined, using both individual and group indicators. At exit, participants reported experiencing physical aggression (12.3%) and sexual aggression (12.6%) at the club. Using generalized linear mixed modeling to account for nested data (club, event, and group), group level indicators predicted both the individual's physical and sexual aggression experiences. Especially for experiences of physical aggression, group effects are notable. Being in a group whose members recently experienced physical aggression, increased the risk for the individual. Interestingly, groups that had higher levels of planned intoxication decreased risks of experiencing aggression, while a discrepancy in these intentions among group members increased the risks. Group effects were also noted for experiencing sexual aggression. High levels of prior experiences for sexual aggression in the group increased the risks for the individual during the event. Also, being in a group that is identified as having at least one member who is frequently drunk, increases the risk for experiencing sexual aggression. These findings inform prevention strategies for young adults engaged in high risk behaviors by targeting social drinking groups who frequent clubs. PMID:24838821

  7. Brazil to Join the European Southern Observatory

    2010-12-01

    The Federative Republic of Brazil has yesterday signed the formal accession agreement paving the way for it to become a Member State of the European Southern Observatory (ESO). Following government ratification Brazil will become the fifteenth Member State and the first from outside Europe. On 29 December 2010, at a ceremony in Brasilia, the Brazilian Minister of Science and Technology, Sergio Machado Rezende and the ESO Director General, Tim de Zeeuw signed the formal accession agreement aiming to make Brazil a Member State of the European Southern Observatory. Brazil will become the fifteen Member State and the first from outside Europe. Since the agreement means accession to an international convention, the agreement must now be submitted to the Brazilian Parliament for ratification [1]. The signing of the agreement followed the unanimous approval by the ESO Council during an extraordinary meeting on 21 December 2010. "Joining ESO will give new impetus to the development of science, technology and innovation in Brazil as part of the considerable efforts our government is making to keep the country advancing in these strategic areas," says Rezende. The European Southern Observatory has a long history of successful involvement with South America, ever since Chile was selected as the best site for its observatories in 1963. Until now, however, no non-European country has joined ESO as a Member State. "The membership of Brazil will give the vibrant Brazilian astronomical community full access to the most productive observatory in the world and open up opportunities for Brazilian high-tech industry to contribute to the European Extremely Large Telescope project. It will also bring new resources and skills to the organisation at the right time for them to make a major contribution to this exciting project," adds ESO Director General, Tim de Zeeuw. The European Extremely Large Telescope (E-ELT) telescope design phase was recently completed and a major review was

  8. Modeling Non-homologous End Joining

    Li, Yongfeng

    2013-01-01

    Non-homologous end joining (NHEJ) is the dominant DNA double strand break (DSB) repair pathway and involves several NHEJ proteins such as Ku, DNA-PKcs, XRCC4, Ligase IV and so on. Once DSBs are generated, Ku is first recruited to the DNA end, followed by other NHEJ proteins for DNA end processing and ligation. Because of the direct ligation of break ends without the need for a homologous template, NHEJ turns out to be an error-prone but efficient repair pathway. Some mechanisms have been proposed of how the efficiency of NHEJ repair is affected. The type of DNA damage is an important factor of NHEJ repair. For instance, the length of DNA fragment may determine the recruitment efficiency of NHEJ protein such as Ku [1], or the complexity of the DNA breaks [2] is accounted for the choice of NHEJ proteins and subpathway of NHEJ repair. On the other hand, the chromatin structure also plays a role of the accessibility of NHEJ protein to the DNA damage site. In this talk, some mathematical models of NHEJ, that consist of series of biochemical reactions complying with the laws of chemical reaction (e.g. mass action, etc.), will be introduced. By mathematical and numerical analysis and parameter estimation, the models are able to capture the qualitative biological features and show good agreement with experimental data. As conclusions, from the viewpoint of modeling, how the NHEJ proteins are recruited will be first discussed for connection between the classical sequential model [4] and recently proposed two-phase model [5]. Then how the NHEJ repair pathway is affected, by the length of DNA fragment [6], the complexity of DNA damage [7] and the chromatin structure [8], will be addressed

    We will present an overview of the current real-time video service offering for the LHC, in particular the operation of the CERN Vidyo service will be described in terms of consolidated performance and scale: The service is an increasingly critical part of the daily activity of the LHC collaborations, topping recently more than 50 million minutes of communication in one year, with peaks of up to 852 simultaneous connections. We will elaborate on the improvement of some front-end key features such as the integration with CERN Indico, or the enhancements of the Unified Client and also on new ones, released or in the pipeline, such as a new WebRTC client and CERN SSO/Federated SSO integration. An overview of future infrastructure improvements, such as virtualization techniques of Vidyo routers and geo-location mechanisms for load-balancing and optimum user distribution across the service infrastructure will also be discussed. The work done by CERN to improve the monitoring of its Vidyo network will also be presented and demoed. As a last point, we will touch the roadmap and strategy established by CERN and Vidyo with a clear objective of optimizing the service both on the end client and backend infrastructure to make it truly universal, to serve Global Science. To achieve those actions, the introduction of the multitenant concept to serve different communities is needed. This is one of the consequences of CERN's decision to offer the Vidyo service currently operated for the LHC, to other Sciences, Institutions and Virtual Organizations beyond HEP that might express interest for it.

  17. Solid State Joining of Dissimilar Titanium Alloys

    NASA Astrophysics Data System (ADS)

    Morton, Todd W.

    Solid state joining of titanium via friction stir welding and diffusion bonding have emerged as enablers of efficient monolithic structural designs by the eliminations fasteners for the aerospace industry. As design complexity and service demands increase, the need for joints of dissimilar alloys has emerged. Complex thermomechanical conditions in friction stir weld joints and high temperature deformation behavior differences between alloys used in dissimilar joints gives rise to a highly variable flow pattern within a stir zone. Experiments performed welding Ti-6Al-4V to beta21S show that mechanical intermixing of the two alloys is the primary mechanism for the generation of the localized chemistry and microstructure, the magnitude of which can be directly related to pin rotation and travel speed weld parameters. Mechanical mixing of the two alloys is heavily influenced by strain rate softening phenomena, and can be used to manipulate weld nugget structure by switching which alloy is subjected to the advancing side of the pin. Turbulent mixing of a weld nugget and a significant reduction in defects and weld forces are observed when the beta21S is put on the advancing side of the weld where higher strain rates are present. Chemical diffusion driven by the heat of weld parameters is characterized using energy dispersive x-ray spectroscopy (EDS) and is shown to be a secondary process responsible for generating short-range chemical gradients that lead to a gradient of alpha particle structures. Diffusion calculations are inconsistent with an assumption of steady-state diffusion and show that material interfaces in the weld nugget evolve through the break-down of turbulent interface features generated by material flows. A high degree of recrystallization is seen throughout the welds, with unique, hybrid chemistry grains that are generated at material interfaces in the weld nugget that help to unify the crystal structure of dissimilar alloys. The degree of

    2013-05-21

    A method of joining at least two parts includes steps of dispersing a joining material comprising a multi-phase magnetic metal-aluminum powder at an interface between the at least two parts to be joined and applying an alternating magnetic field (AMF). The AMF has a magnetic field strength and frequency suitable for inducing magnetic hysteresis losses in the metal-aluminum powder and is applied for a period that raises temperature of the metal-aluminum powder to an exothermic transformation temperature. At the exothermic transformation temperature, the metal-aluminum powder melts and resolidifies as a metal aluminide solid having a non-magnetic configuration.

    Cloud resources nowadays contribute an essential share of resources for computing in high-energy physics. Such resources can be either provided by private or public IaaS clouds (e.g. OpenStack, Amazon EC2, Google Compute Engine) or by volunteers computers (e.g. LHC@Home 2.0). In any case, experiments need to prepare a virtual machine image that provides the execution environment for the physics application at hand. The CernVM virtual machine since version 3 is a minimal and versatile virtual machine image capable of booting different operating systems. The virtual machine image is less than 20 megabyte in size. The actual operating system is delivered on demand by the CernVM File System. CernVM 3 has matured from a prototype to a production environment. It is used, for instance, to run LHC applications in the cloud, to tune event generators using a network of volunteer computers, and as a container for the historic Scientific Linux 5 and Scientific Linux 4 based software environments in the course of long-term data preservation efforts of the ALICE, CMS, and ALEPH experiments. We present experience and lessons learned from the use of CernVM at scale. We also provide an outlook on the upcoming developments. These developments include adding support for Scientific Linux 7, the use of container virtualization, such as provided by Docker, and the streamlining of virtual machine contextualization towards the cloud-init industry standard.

    Bombard, Britain

    Students from an urban middle school participated in a Science Book Club for one semester using the literature circles format. These students voluntarily attended twice weekly lunch meetings, reading books that followed their Grade 7 science classes. Groups of three to six participants read the same text, each performing rotating jobs to improve group discussions during meetings. When a group completed a book, participants created a presentation to share what they learned with the other groups in the club and the researcher/teacher. This research measured gains in science content knowledge and language arts skills focusing on reading comprehension, and literary response and analysis. Gains were measured using pre-existing district benchmarks. An ANCOVA showed that while no gains were found in science content knowledge, there were gains in language arts in the areas of reading comprehension and literary response and analysis.

  13. Joining of Aluminium Alloy Sheets by Rectangular Mechanical Clinching

    Abe, Y.; Mori, K.; Kato, T.

    2011-05-04

    A mechanical clinching has the advantage of low running costs. However, the joint strength is not high. To improve the maximum load of the joined sheets by a mechanical clinching, square and rectangular mechanical clinching were introduced. In the mechanical clinching, the two sheets are mechanically joined by forming an interlock between the lower and upper sheets by the punch and die. The joined length with the interlock was increased by the rectangular punch and die. The deforming behaviours of the sheets in the mechanical clinching were investigated, and then the interlock in the sheets had distribution in the circumference of the projection. Although the interlocks were formed in both projection side and diagonal, the interlock in the diagonal was smaller because of the long contact length between the lower sheet and the die cavity surface. The maximum load of the joined sheets by the rectangular mechanical clinching was two times larger than the load by the round mechanical clinching.

    Potential applications of SiC include components for advanced turbine engines, tube assemblies for radiant burners and petrochemical processing and heat exchangers for high efficiency electric power generation systems. Reliable methods for joining SiC are required in order to cost-effectively fabricate components for these applications from commercially available shapes and sizes. This manuscript reports the results of microwave joining experiments performed using two different types of SiC materials. The first were on reaction bonded SiC, and produced joints with fracture toughness equal to or greater than that of the base material over an extended range of joining temperatures. The second were on continuous fiber-reinforced SiC/SiC composite materials, which were successfully joined with a commercial active brazing alloy, as well as by using a polymer precursor.

    The main objective of this project was to develop reliable, low-cost techniques for joining silicon nitride (Si{sub 3}N{sub 4}) to itself and to metals. For Si{sub 3}N{sub 4} to be widely used in advanced turbomachinery applications, joining techniques must be developed that are reliable, cost-effective, and manufacturable. This project addressed those needs by developing and testing two Si{sub 3}N{sub 4} joining systems; oxynitride glass joining materials and high temperature braze alloys. Extensive measurements were also made of the mechanical properties and oxidation resistance of the braze materials. Finite element models were used to predict the magnitudes and positions of the stresses in the ceramic regions of ceramic-to-metal joints sleeve and butt joints, similar to the geometries used for stator assemblies.

    A unique, small-scale, ribbon explosive joining process is being developed as an option for closing and sealing a metal canister to allow the return of a pristine sample of the Martian surface and atmosphere to Earth. This joining process is accomplished by an explosively driven, high-velocity, angular collision of the metal, which melts and effaces the oxide films from the surfaces to allow valence electron sharing to bond the interface. Significant progress has been made through more than 100 experimental tests to meet the goals of this ongoing developmental effort. The metal of choice, aluminum alloy 6061, has been joined in multiple interface configurations and in complete cylinders. This process can accommodate dust and debris on the surfaces to be joined. It can both create and sever a joint at its midpoint with one explosive input. Finally, an approach has been demonstrated that can capture the back blast from the explosive.

    Harada, Yasunori

    2011-01-01

    In shot peening the substrate undergoes large plastic deformation near the surface due to the hit with shots. The plastic flow areas formed by cold working may form the surface layer. Authors have recently proposed new joining methods using shot peening, shot lining and shot caulking. Our approach has been applied to the butt joining of the dissimilar metal sheets. In the present study, joining of thin metal sheets using a shot peening process was investigated to improve the joinability. In the joined section, the edge of sheets is the equally-spaced slits. In this method, the convex edges of the sheet are laid on top of the other sheet. Namely, the two sheets are superimposed in the joining area. When the connection is shot-peened, the material of the convex area undergoes large plastic deformation near the surface due to the collision of shots. In this process, particularly noteworthy is the plastic flow near surface layer. The convex edges of the sheet can be joined to the other sheet, thus two sheets are joined each other. In the experiment, the shot peening treatment was performed by using an air-type peening machine. The shots used were made of high carbon cast steel. Air pressure was 0.6 MPa and peening time was in the range of 30-150s. The peening conditions were controlled in the experiment. The thin sheets were commercial low-carbon steel, stainless steel, pure aluminum, and aluminium alloy. The effects of processing conditions on the joinability were mainly examined. The joint strength increased with the kinetic energy of shots. It was found that the present method was effective for joining of thin metal sheets.

    Trachoma was widespread in Japan in the early 1950s. In February of 1952 the Suita Mothers' Club started its checkup campaign for the prevention of trachoma. When the club was formed there were many flies and mosquitos throughout the city. Both flies and mosquitos carry or spread dangerous diseases. The Club began thinking seriously about the extermination of these insects. Additionally, one of the dampest areas in the city was selected as a model area for pest eradication. A 5-year plan was designed. The plan included cleaning up of family homes and vacant lots. The Suita Mothers' Club was also responsible for a program to strike out tuberculosis, as well as a program to prevent cerebral apoplexy. The Club has lasted about 35 years. It publishes a newsletter every month. Club members believe it is important to think as a group and act as a group.

  4. Drink-driving in community sports clubs: adopting the Good Sports alcohol management program.

    Rowland, Bosco; Toumbourou, John; Allen, Felicity

    2012-09-01

    Throughout the developed world, community sports clubs are a high-risk setting for alcohol-impaired driving. The Good Sports program accredits community sports clubs to encourage implementation of alcohol-focussed harm-reduction and safe-transport strategies. This study tested for associations between participation in the Good Sports program and reduced rates of drink-driving amongst club members. Multilevel modelling indicated that for each season a club was in the program there was an 8% reduction in the odds of drink-driving. These findings may arise due to clubs with lower rates of alcohol use maintaining longer involvement in the program. However, the findings are also compatible with the intention of the Good Sports program to reduce the risk that club members will drive whilst alcohol impaired.

  6. [Club drugs: old medicines as new party drugs].

    PubMed

    2004-09-11

    During the last few years the term club drugs has been used for defining an heterogeneous group of chemical substances in permanent evolution, that are consumed for recreational purposes. These substances have been extensively used, firstly by the Rave culture and later by the so called Club culture. These movements are characterized by the search of amplified sensations, by means of the combination of electronic music, marathon dancing and substance abuse. After years with a predominating consumption of designer amphetamines in these groups, it seems that the use of another type of substances is increasing, fundamentally drugs with hallucinogenic effects. This review focus in four of these substances; ketamine, dextromethorphan, nitrous oxide and gamma-hydroxybutyric acid (GHB, liquid ecstasy), and includes a discussion of their pharmacology, recreational use, adverse effects and patient management. These drugs are, at he same time, drugs of abuse and medicines with concrete indications in therapeutics, with an important increase of their consumption in the last few years. The Rave and Club cultures are also described.

  8. Laser-generated Macroscopic and Microscopic Surface Structures for the Joining of Aluminum and Thermoplastics using Friction Press Joining

    NASA Astrophysics Data System (ADS)

    Fuchs, Alexander N.; Wirth, Franz X.; Rinck, Philipp; Zaeh, Michael F.

    Structural lightweight construction is increasingly utilized in the aerospace and automotive industry. Hybrid structures have great potential, especially with regard to load-specific component layouts. Usually, a surface pre-treatment is applied prior to joining dissimilar materials to improve bonding mechanisms such as form closure. In previous studies pulsed wave (pw) lasers were used for structuring metals. This paper presents the results of aluminum pre-treatment via a continuous wave (cw) single-mode fiber laser: macroscopic and microscopic structures were generated on the aluminum surface; the samples were joined with glass fiber reinforced polyamide using Friction Press Joining (FPJ), a method for joining metals and thermoplastic polymers in lap joint configuration. Using these new methods for surface structuring, shear strength was increased by 40% compared to previous studies with pw lasers.

    PubMed Central

    Quennerstedt, Mikael; Eriksson, Charli

    2013-01-01

    Aims: The aims of this review is to compile and identify key issues in international research about youth sports clubs as health-promoting settings, and then discuss the results of the review in terms of a framework for the youth sports club as a health-promoting setting. Methods: The framework guiding this review of research is the health-promoting settings approach introduced by the World Health Organization (WHO). The method used is the integrated review. Inclusion criteria were, first, that the studies concerned sports clubs for young people, not professional clubs; second, that it be a question of voluntary participation in some sort of ongoing organized athletics outside of the regular school curricula; third, that the studies consider issues about youth sports clubs in terms of health-promoting settings as described by WHO. The final sample for the review consists of 44 publications. Results: The review shows that youth sports clubs have plentiful opportunities to be or become health-promoting settings; however this is not something that happens automatically. To do so, the club needs to include an emphasis on certain important elements in its strategies and daily practices. The youth sports club needs to be a supportive and healthy environment with activities designed for and adapted to the specific age-group or stage of development of the youth. Conclusions: To become a health-promoting setting, a youth sports club needs to take a comprehensive approach to its activities, aims, and purposes. PMID:23349167

  10. Undergraduate journal club as an intervention to improve student development in applying the scientific process

    2016-01-01

    Active learning improves student performance in STEM courses. Exposure to active learning environments generally occurs through traditional laboratory courses and independent research, both of which require access to resources that are limited at many universities. A previously reported active learning-based undergraduate journal club improved student achievement in communicating science. Here, we expanded on this previous journal club to improve student performance in the process of science. We developed and implemented a series of workshops and seminars referred to as “CASL Club,” an undergraduate journal club targeted at improving student development in applying the scientific process. Students were surveyed before and after CASL club about their confidence in accessing, analyzing, and reporting scientific research. Post-CASL club, the students reported increases in confidence in their abilities to access and present scientific articles and write scientific abstracts. Additionally, the students reported improved confidence and performance in their courses. Compared to the previous journal club study, the majority of sampled journal club participants were not exposed to primary literature as part of their general coursework. Our results illustrate active-learning based undergraduate journal clubs as a way to expose students to primary literature and improve students’ ability to apply scientific process in an active-learning environment at resource-limited universities.

    2008-04-01

    Over the past 15 years a worldwide Detector R&D Programme has made the LHC experiments possible. These experiments operate at a new level of event rate and detection capabilities. Based on these advances, Detector R&D is continuing at CERN in close collaboration with University and Research Institutes. Several main directions are being pursued for solid-state and gaseous tracking devices, advanced crystal and noble liquid calorimetry, particle identification methods, and advanced signal-processing techniques. This effort is directed towards experiments at even higher collision rates at the LHC, the requirements for the next generation of linear electron-positron colliders and for applications outside particle physics, such as medical diagnostics instrumentation. We shall illustrate this challenging, stimulating and creative programme with examples and show how these developments are taking place in close collaboration between CERN and institutions around the globe.

    2014-06-01

    On 4 July 2012, particle physics became a celebrity. Around 1,000,000,000 people (yes, 1 billion) [1] saw rebroadcasts of two technical presentations announcing the discovery of a new boson. The occasion was a joint seminar of the CMS [2] and ATLAS [3] collaborations, and the target audience were particle physicists. Yet the world ate it up like a sporting event. Roughly two days later, in a parallel session of ICHEP in Melbourne, Australia [4], a group of physicists decided to explain the significance of this discovery to the public. They used a tool called "Hangout", part of the relatively new Google+ social media platform [5], to converse directly with the public via a webcast videoconference. The demand to join this Hangout [6] overloaded the server several times. In the end, a compromise involving Q&A via comments was set up, and the conversation was underway. We present a new project born shortly after this experience called Hangout with CERN [7], and discuss its success in creating an effective conversational channel between the public and particle physicists. We review earlier efforts by both CMS and ATLAS contributing to this development, and then describe the current programme, involving nearly all aspects of CERN, and some topics that go well beyond that. We conclude by discussing the potential of the programme both to improve our accountability to the public and to train our community for public communication.

  14. The Harrow Slimming Club: analysis of the results obtained in 249 members of a self-financing, non-profit-making group.

    PubMed

    Seddon, R; Penfound, J; Garrow, J S

    1981-04-01

    Between January 1977 and August 1979 there have been 14 courses at the Harrow Slimming Club--a non-profit-making group run by the Harrow Health District using local authority premises, and with trained dietitians as course counsellors. The administrative structure, recruitment procedures and dietary advice are described. The 249 course members were typically moderately-obese middle-aged women, but there was a wide range in both age and in severity of obesity. During the initial ten-week course the average attendance was 7.1 sessions per person, and the average weight loss was 4.4 kg. Members who attended more regularly showed greater weight losses. Those members who attended regularly were eligible to join follow-up courses, and 110 members took this option. The average attendance at follow-up was 9.2 sessions per person with a small further weight loss, but again there was wide variation about this average figure. The results compare very favourably with those obtained either by commercial slimming clubs or hospital obesity clinics.

  15. Aeroelastic tailoring and structural optimization of joined-wing configurations

    NASA Astrophysics Data System (ADS)

    Lee, Dong-Hwan

    2002-08-01

    Methodology for integrated aero-structural design was developed using formal optimization. ASTROS (Automated STRuctural Optimization System) was used as an analyzer and an optimizer for performing joined-wing weight optimization with stress, displacement, cantilever or body-freedom flutter constraints. As a pre/post processor, MATLAB was used for generating input file of ASTROS and for displaying the results of the ASTROS. The effects of the aeroelastic constraints on the isotropic and composite joined-wing weight were examined using this developed methodology. The aeroelastic features of a joined-wing aircraft were examined using both the Rayleigh-Ritz method and a finite element based aeroelastic stability and weight optimization procedure. Aircraft rigid-body modes are included to analyze of body-freedom flutter of the joined-wing aircraft. Several parametric studies were performed to determine the most important parameters that affect the aeroelastic behavior of a joined-wing aircraft. The special feature of a joined-wing aircraft is body-freedom flutter involving frequency interaction of the first elastic mode and the aircraft short period mode. In most parametric study cases, the body-freedom flutter speed was less than the cantilever flutter speed that is independent of fuselage inertia. As fuselage pitching moment of inertia was increased, the body-freedom flutter speed increased. When the pitching moment of inertia reaches a critical value, transition from body-freedom flutter to cantilever flutter occurred. The effects of composite laminate orientation on the front and rear wings of a joined-wing configuration were studied. An aircraft pitch divergence mode, which occurred because of forward movement of center of pressure due to wing deformation, was found. Body-freedom flutter and cantilever-like flutter were also found depending on combination of front and rear wing ply orientations. Optimized wing weight behaviors of the planar and non

    NASA Technical Reports Server (NTRS)

    Bement, Laurence J. (Inventor); Kushnick, Anne C. (Inventor)

    1991-01-01

    The invention is an apparatus and method for wire splicing using an explosive joining process. The apparatus consists of a prebent, U-shaped strap of metal that slides over prepositioned wires. A standoff means separates the wires from the strap before joining. An adhesive means holds two ribbon explosives in position centered over the U-shaped strap. A detonating means connects to the ribbon explosives. The process involves spreading strands of each wire to be joined into a flat plane. The process then requires alternating each strand in alignment to form a mesh-like arrangement with an overlapped area. The strap slides over the strands of the wires, and the standoff means is positioned between the two surfaces. The detonating means then initiates the ribbon explosives that drive the strap to accomplish a high velocity, angular collision between the mating surfaces. This collision creates surface melts and collision bonding results in electron sharing linkups.

  17. Hot-isostatic-press joining of cemented carbides

    SciTech Connect

    Miodownik, M.; Derby, B.

    1999-12-01

    Hot isostatic pressing (HIPing) is investigated as a technique for joining the cermet AC-15% Co to itself. Encapsulation of the specimens prior to HIPing was carried out using steel encapsulation, glass encapsulation, and self-encapsulation. The bonds were evaluated using a four-point-bend method. It is shown that the glass and steel encapsulation methods have a number of inherent problems which make them inappropriate for near net shape processing. In contrast the novel self-encapsulation method, described for the first time in this communication, is both simple and effective, producing joined material with bulk strength. The concept of self-encapsulation is potentially widely applicable for joining composite materials.

  18. Advances in Solid State Joining of High Temperature Alloys

    NASA Technical Reports Server (NTRS)

    Ding, Jeff; Schneider, Judy

    2011-01-01

    Many of the metals used in the oil and gas industry are difficult to fusion weld including Titanium and its alloys. Solid state joining processes are being pursued as an alternative process to produce robust structures more amenable to high pressure applications. Various solid state joining processes include friction stir welding (FSW) and a patented modification termed thermal stir welding (TSW). The configuration of TSWing utilizes an induction coil to preheat the material minimizing the burden on the weld tool extending its life. This provides the ability to precisely select and control the temperature to avoid detrimental changes to the microstructure. The work presented in this presentation investigates the feasibility of joining various titanium alloys using the solid state welding processes of FSW and TSW. Process descriptions and attributes of each weld process will be presented. Weld process set ]up and welding techniques will be discussed leading to the challenges experienced. Mechanical property data will also be presented.

    Complex systems are often characterized by large-scale hierarchical organizations. Whether the prominent elements, at the top of the hierarchy, share and control resources or avoid one another lies at the heart of a system's global organization and functioning. Inspired by network perspectives, we propose a new general framework for studying the tendency of prominent elements to form clubs with exclusive control over the majority of a system's resources. We explore associations between prominence and control in the fields of transportation, scientific collaboration, and online communication.

    Atrial septal aneurysm (ASA) is a localised "saccular" deformity which protrudes to the right or the left atrium or on both sides. It is a rare, but well recognised cardiac abnormality. It is usually an incidental finding or may presents as atrial arrhythmias or arterial embolism. Though it is an acyanotic congenital heart disease but it may result in significant right to left shunt and cyanosis. We describe a patient of ASA with atrial septal defect who presented with clubbing and right to left shunt without clinically apparent cyanosis. PMID:27608873

    1987-01-01

    A tool and process to be used in the explosive joining of tubes is disclosed. The tool consists of an initiator, a tool form, and a ribbon explosive. The assembled tool is a compact, storable, and safe device suitable for explosive joining of small, lightweight tubes down to 0.20 inch in diameter. The invention is inserted into either another tube or a tube plate. A shim or standoff between the two surfaces to be welded is necessary. Initiation of the explosive inside the tube results in a high velocity, angular collision between the mating surfaces. This collision creates surface melts and collision bonding wherein electron-sharing linkups are formed.

    Steady-state creep and joining of alumina/zirconia composites containing alumina volume fractions of 20, 60 and 85% have been investigated between 1,250 and 1,350 C. Superplasticity of these compounds is controlled by grain-boundary sliding and the creep rate is a function of alumina volume fraction, not grain size. Using the principles of superplasticity, pieces of the composite have been joined by applying the stress required to achieve 5 to 10% strain to form a strong interface at temperatures as low as 1,200 C.

  18. Making sporting clubs healthy and welcoming environments: a strategy to increase participation.

    Eime, Rochelle M; Payne, Warren R; Harvey, Jack T

    2008-04-01

    Sporting clubs are an ideal setting to promote community-wide participation in physical activity. Using the principles of the Ottawa Charter as a guide, this study explored the factors affecting the development of supportive environments as a mechanism to increase participation in club sport. The Victorian Health Promotion Foundation (VicHealth) funds State Sporting Associations (SSAs) to develop healthy and welcoming environments (HWE) in their associated clubs. The program focus areas are: welcoming and inclusive environments, sports injury prevention, 'smoke-free' environments, responsible serving of alcohol, sun protection and healthy eating. This paper sought to determine whether or not SSA Executive Officers (EOs) believe that the creation of a supportive environment will facilitate sporting club membership and to identify the factors that affect the development of the HWEs. Forty-two (82.4%) of the 51 funded SSAs completed a general survey and 36 (70.6%) of EOs responded to questions that were specifically addressed to them. EOs from six SSAs also participated in semi-structured interviews. SSA EOs (97.2%) believed that the creation of HWE in clubs would facilitate increases in participant membership. However, the data indicate incomplete development of the HWE focus areas at the club level because of limited club capacity and limited SSA support. Reportedly, the SSAs are at the stage of raising program awareness at the club level. It is suggested that SSAs should plan a structured approach to the development of HWEs that acknowledges the diverse capacity of their clubs, and garner the support of key club volunteers in order to establish HWEs.

    The NASA John H. Glenn Research Center initiated baseline testing of the Club Car Carryall with asymmetric ultracapacitors as a way to reduce pollution in industrial settings, reduce fossil fuel consumption, and reduce operating costs for transportation systems. The Club Car Carryall provides an inexpensive approach to advance the state of the art in electric vehicle technology in a practical application. The project transfers space technology to terrestrial use via non-traditional partners, and provides power system data valuable for future space applications. The work was done under the Hybrid Power Management (HPM) Program, which includes the Hybrid Electric Transit Bus (HETB). The Carryall is a state of the art, ground up, electric utility vehicle. A unique aspect of the project was the use of a state of the art, long life ultracapacitor energy storage system. Innovative features, such as regenerative braking through ultracapacitor energy storage, are planned. Regenerative braking recovers much of the kinetic energy of the vehicle during deceleration. The Carryall was tested with the standard lead acid battery energy storage system, as well as with an asymmetric ultracapacitor energy storage system. The report concludes that the Carryall provides excellent performance, and that the implementation of asymmetric ultracapacitors in the power system can provide significant performance improvements.

  20. Participation in a Video Club: Influences on Teachers and Teaching

    NASA Astrophysics Data System (ADS)

    Barnhart, Tara

    This dissertation examines the development of critical colleagueship among five secondary science teachers in a semester-long video club. The design of the video club was intended to promote a focus on student thinking and experimentation with elements of ambitious science teaching. Over time, participants sustained a focus on interpreting students' disciplinary thinking using evidence and began to problematize aspects of instruction related to making student thinking visible. Some participants attempted to change instruction to gain greater access to students' disciplinary thinking while others did not. Efforts to experiment with instructional practice appeared related to alignment between participants' learning goals and curricular contexts and the goals of the professional development design. Features such as framing activities, types of artifacts used, and facilitation, interacted differently over time to influence participant learning. Analysis revealed various tensions among the elements of the learning ecology that influenced participation. Findings from this study contribute to what is known about the importance of skilled facilitation as part of a learning ecology (Cobb, Confrey, diSessa, Lehrer, & Schauble, 2003) and has implications for the design of site-based professional development with secondary teachers.

  1. CERN alerter—RSS based system for information broadcast to all CERN offices

    NASA Astrophysics Data System (ADS)

    Otto, R.

    2008-07-01

    Nearly every large organization uses a tool to broadcast messages and information across the internal campus (messages like alerts announcing interruption in services or just information about upcoming events). These tools typically allow administrators (operators) to send 'targeted' messages which are sent only to specific groups of users or computers, e/g only those located in a specified building or connected to a particular computing service. CERN has a long history of such tools: CERNVMS's SPM_quotMESSAGE command, Zephyr [2] and the most recent the NICE Alerter based on the NNTP protocol. The NICE Alerter used on all Windows-based computers had to be phased out as a consequence of phasing out NNTP at CERN. The new solution to broadcast information messages on the CERN campus continues to provide the service based on cross-platform technologies, hence minimizing custom developments and relying on commercial software as much as possible. The new system, called CERN Alerter, is based on RSS (Really Simple Syndication) [9] for the transport protocol and uses Microsoft SharePoint as the backend for database and posting interface. The windows-based client relies on Internet Explorer 7.0 with custom code to trigger the window pop-ups and the notifications for new events. Linux and Mac OS X clients could also rely on any RSS readers to subscribe to targeted notifications. The paper covers the architecture and implementation aspects of the new system.

  4. Efficient and Scalable Graph Similarity Joins in MapReduce

    Chen, Yifan; Zhang, Weiming; Tang, Jiuyang

    2014-01-01

    Along with the emergence of massive graph-modeled data, it is of great importance to investigate graph similarity joins due to their wide applications for multiple purposes, including data cleaning, and near duplicate detection. This paper considers graph similarity joins with edit distance constraints, which return pairs of graphs such that their edit distances are no larger than a given threshold. Leveraging the MapReduce programming model, we propose MGSJoin, a scalable algorithm following the filtering-verification framework for efficient graph similarity joins. It relies on counting overlapping graph signatures for filtering out nonpromising candidates. With the potential issue of too many key-value pairs in the filtering phase, spectral Bloom filters are introduced to reduce the number of key-value pairs. Furthermore, we integrate the multiway join strategy to boost the verification, where a MapReduce-based method is proposed for GED calculation. The superior efficiency and scalability of the proposed algorithms are demonstrated by extensive experimental results. PMID:25121135

  5. Embedded Heaters for Joining or Separating Plastic Parts

    Bryant, Melvin A., III

    2004-01-01

    A proposed thermal-bonding technique would make it possible to join or separate thermoplastic parts quickly and efficiently. The technique would eliminate the need for conventional welding or for such conventional fastening components as bolted flanges or interlocking hooks. The technique could be particularly useful in the sign industry (in which large quantities of thermoplastics are used) or could be used to join plastic pipes. A thin sheet of a suitable electrically conductive material would be formed to fit between two thermoplastic parts to be joined (see figure). The electrically conductive sheet and the two parts would be put together tightly, then an electrical current would be sent through the conductor to heat the thermoplastic locally. The magnitude of the current and the heating time would be chosen to generate just enough heat to cause the thermoplastic to adhere to both sides of the electrically conductive sheet. Optionally, the electrically conductive sheet could contain many small holes to provide purchase or to increase electrical resistance to facilitate the generation of heat. After thermal bonding, the electrically conductive sheet remains as an integral part of the structure. If necessary, the electrically conductive sheet can be reheated later to separate the joined thermoplastic parts.

    Systems requirements for complex spacecraft drive design requirements that lead to structures, components, and/or enclosures of a multi-material and multifunctional design. The varying physical properties of aluminum, tungsten, Invar, or other high-grade aerospace metals when utilized in conjunction with lightweight composites multiply system level solutions. These multi-material designs are largely dependent upon effective joining techAn improved method of joining metal components to matrix/fiber composite material structures has been invented. The method is particularly applicable to equipping such thin-wall polymer-matrix composite (PMC) structures as tanks with flanges, ceramic matrix composite (CMC) liners for high heat engine nozzles, and other metallic-to-composite attachments. The method is oriented toward new architectures and distributing mechanical loads as widely as possible in the vicinities of attachment locations to prevent excessive concentrations of stresses that could give rise to delaminations, debonds, leaks, and other failures. The method in its most basic form can be summarized as follows: A metal component is to be joined to a designated attachment area on a composite-material structure. In preparation for joining, the metal component is fabricated to include multiple studs projecting from the aforementioned face. Also in preparation for joining, holes just wide enough to accept the studs are molded into, drilled, or otherwise formed in the corresponding locations in the designated attachment area of the uncured ("wet') composite structure. The metal component is brought together with the uncured composite structure so that the studs become firmly seated in the holes, thereby causing the composite material to become intertwined with the metal component in the joining area. Alternately, it is proposed to utilize other mechanical attachment schemes whereby the uncured composite and metallic parts are joined with "z-direction" fasteners. The

    2010-04-01

    The ALICE experiment at CERN LHC is using a PROOF-enabled cluster for fast physics analysis, detector calibration and reconstruction of small data samples. The current system (CAF - CERN Analysis Facility) consists of some 120 CPU cores and about 45 TB of disk space distributed across the CAF hosts. One of the most important aspects of the data analysis on the CAF is the speed with which it can be carried out. The system is particularly aimed at the prototyping phase of analyses that need a high number of iterations and thus require a short response time. Quasi-online quality assurance of data can be obtained. The paper describes the design principles of the PROOF framework and presents the current setup, performance tests and usage statistics. Subsets of selected data can be automatically staged in CAF from the Grid storage systems, therefore data distribution and staging techniques are described in depth. A fairshare algorithm to adjust the priorities of concurrently running sessions is also examined. Furthermore, the adaptation of PROOF to the AliEn/gLite Grid middleware is described. This approach enables a dynamic startup of PROOF nodes worldwide with the purpose to process much larger physics datasets.

    Arthralgia in childhood is an unspecific symptom. One rare cause of arthralgia is hypertrophic osteoarthropathy associated with digital clubbing. We present a child where hypertrophic osteoarthropathy led to the rare diagnosis of an inflammatory pseudotumour of the lung. In a 12-year-old girl with arthralgia and digital clubbing, a chest radiograph disclosed a large round mass in the right upper lobe, and the following chest computed tomography scan showed a large solid homogenous, round, well marginated lesion with little contrast enhancement. A lobectomy of the right upper lobe was performed, and histological examination showed an inflammatory pseudotumour. The postoperative course was without problems: arthralgia and digital clubbing disappeared.

    For decades, films across the world have entertained people and affected their attitudes regarding certain issues and conditions. Documentary films have been used by governments in different parts of the world to educate the general public and promote health and prevent the spread of disease as part of public health programs. Psychiatry as a branch of medicine like the rest of medicine continues to develop. With an increasing awareness among the general population and popularity of films showing various aspects of mental illnesses on the rise, educators and teachers are turning their attention to using films for education of medical students and psychiatric trainees. Although films may be stereotypical and prejudiced, they can be used successfully in teaching psychiatry trainees. In this paper, development of a movie club and its use are described and suggestions made to improve the use of films in this process.

    The design, manufacture, and experimental analysis of structural materials capable of operation in the high temperatures, corrosive environments, and radiation damage spectra of future reactor designs remain one of the key pacing items for advanced reactor designs. The most promising candidate structural materials are vanadium-based refractory alloys, silicon carbide composites and oxide dispersion strengthened steels. Of these, oxide dispersion strengthened steels are a likely near-term candidate to meet required demands. This paper reviews different variants of oxide dispersion strengthened steels and discusses their capability with regard to high-temperature strength, corrosion resistance, and radiation damage resistance. Additionally, joining of oxide dispersion strengthened steels, which has been cited as a limiting factor preventing their use, is addressed and reviewed. Specifically, friction stir welding of these steels is reviewed as a promising joining method for oxide dispersion strengthened steels.

    Many of the metals used in the oil and gas industry are difficult to fusion weld including titanium and its alloys. Thus solid state joining processes, such as friction stir welding (FSWing) and a patented modification termed thermal stir welding (TSWing), are being pursued as alternatives to produce robust structures more amenable to high pressure applications. Unlike the FSWing process where the tool is used to heat the workpiece, TSWing utilizes an induction coil to preheat the material prior to stirring thus minimizing the burden on the weld tool and thereby extending its life. This study reports on the initial results of using a hybrid (H)-TSW process to join commercially pure, 1.3cm thick panels of titanium (CP Ti) Grade 2.

    Joining and integration methods are critically needed as enabling technologies for the full utilization of advanced ceramic components in aerospace and aeronautics applications. One such application is a lean direct injector for a turbine engine to achieve low NOx emissions. In the application, several SiC substrates with different hole patterns to form fuel and combustion air channels are bonded to form the injector. Diffusion bonding is a joining approach that offers uniform bonds with high temperature capability, chemical stability, and high strength. Diffusion bonding was investigated with the aid of titanium foils and coatings as the interlayer between SiC substrates to aid bonding. The influence of such variables as interlayer type, interlayer thickness, substrate finish, and processing time were investigated. Optical microscopy, scanning electron microscopy, and electron microprobe analysis were used to characterize the bonds and to identify the reaction formed phases.

    A joining study of these steels was initiated to determine the feasibility of using ultrahigh carbon steels in structural applications. The high carbon content (1.5 wt%) in these steels and the desire to maintain the superplastic microstructure limit the use of conventional arc-welding processes. We chose two solid-state joining processes: diffusion bonding and inertia friction welding. Preliminary results show that sound bonds can be obtained with tensile properties nearly equal to those of the base metal. Of three UHC steels bonded by both inertia-friction welding and diffusion- bonding processes, the one with the lowest aluminum content had the best overall properties. Diffusion bonding with a nickel interlayer showed the most promising results for the UHC steel containing 1.6 wt% aluminum. The properties of inertia-friction-welded steels can be improved by a post-weld heat treatment.

    Monolithic zirconia (Z) and zirconia-hydroxyapatite (Z/HA) composites were joined by cold isostatic pressing (CIP at 300 MPa) and subsequently by glass-encapsulated hot isostatic pressing (HIP at 1225 C, 1 h and 200 MPa). The physical and mechanical properties of the materials were measured. The fracture surface was studied using a light microscope. The results indicate a strength level of the joint similar to that of the corresponding composite material (Z/HA), 845 and 860 MPa, respectively. Similar experiments with monolithic alumina (A) and alumina-hydroxyapatite (A/HA) were carried out without success. Cracking occurred in the joint area during the cold isostatic pressing process. It seems that ceramics with high green strength and similar green density are essential when joining ceramics by combined CIP and HIP processes.

    Micro and nano-joining has been identified as a key enabling technology in the construction of micromechanical and microelectronic devices. The current article reviews recent progress in micro and nano-joining. In particular, laser micro-welding (LMW) of crossed 316 LVM stainless steel (SS) wire was compared to conventional resistance micro-welding (RMW) and was successfully employed in welding a Pt-Ir /SS dissimilar combination. Welding of Au nanoparticles was realized using femtosecond laser irradiation and its application in the surface enhanced Raman spectroscopy was investigated. Brazing between carbon nanotube (CNT) bundles and Ni electrodes was attained in vacuum, resulting in the development of a novel CNT filament of incandescent lamps.

    The critical need for ceramic joining and integration technologies is becoming better appreciated as the maturity level increases for turbine engine components fabricated from ceramic and ceramic matrix composite materials. Ceramic components offer higher operating temperatures and reduced cooling requirements. This translates into higher efficiencies and lower emissions. For fabricating complex shapes, diffusion bonding of silicon carbide (SiC) to SiC is being developed. For the integration of ceramic parts to the surrounding metallic engine system, brazing of SiC to metals is being developed. Overcoming the chemical, thermal, and mechanical incompatibilities between dissimilar materials is very challenging. This presentation will discuss the types of ceramic components being developed by researchers and industry and the benefits of using ceramic components. Also, the development of strong, crack-free, stable bonds will be discussed. The challenges and progress in developing joining and integration approaches for a specific application, i.e. a SiC injector, will be presented.

    Physical activity is associated with psychosocial and physical health benefits for breast cancer survivors. Little is known, however, about survivors' decision-making processes when considering joining group physical activity programs designed for survivors. Guided by interpretive description methodology (Thorne, 2008), N = 15 breast cancer survivors who were considering or had made the decision to join a dragon boating team were interviewed about their decisions to participate. Four patterns of decision making were identified: searching for a way to care for physical and social needs, taking advantage of opportunities created by breast cancer, dove in with little contemplation, and hesitant to connect with other survivors. Results have implications for understanding decisions to participate in physical activity groups in this population and overcoming challenges to participation.

  12. Becoming stranger: When future selves join the out-group.

    One of the most powerful rules of interpersonal behavior is that people are kinder to members of their in-groups than to members of their out-groups. Are people also kinder to their future selves when they expect them to remain members of their current in-groups rather than become members of their current out-groups? In 2 studies, participants in an emotionally charged debate expected either to remain on the same team or to join the opposing team when they returned the following week. Those who expected to join the opposing team were less willing to sacrifice for their future selves, leaving more of an unpleasant task for their future selves to finish and treating their future selves as unkindly as they treated a stranger. These results suggest that the rules that govern interpersonal behavior may also govern intertemporal behavior, and suggest new strategies to encourage prudent decisions.

    Background Young adulthood (ages 18–25 years) represents a time when high-risk behaviors, including alcohol and drug use, peak. Electronic music dance events (EMDEs) featured at clubs provide an ecologic niche for these high-risk behaviors. Purpose This paper examines the prevalence of alcohol and drug use among EMDE patrons. Examination of personal characteristics associated with exit levels of alcohol and drug use identifies important indicators of risk taking for prevention strategies. Methods Data were collected anonymously during 2010–2012 from 2028 patrons as they entered and exited clubs in the San Francisco Bay area featuring EMDEs. Nearly half were aged ≤25 years. Biological measures of drug and alcohol and self-reported personal characteristics were attained. Analyses were completed in 2012. Results At entrance, more than one fifth of patrons were positive for drug use and one fourth arrived either impaired (blood alcohol concentration [BAC]: 0.05%–0.079%) or intoxicated (BAC: >0.08%) by alcohol. At exit, one fourth tested positive for drugs, and nearly half were impaired or intoxicated by alcohol. Individual characteristics that were important for levels of risk included prior alcohol use behaviors, sexual identity, ethnic/racial identity, and transportation to the event. Gender did not differentiate for alcohol use but fewer women used drugs. Conclusions Findings confirm the importance of targeting EMDEs for prevention efforts. EMDEs attract young working adults who are engaged in heavy alcohol and/or drug use. Targeting these social settings for delivering public health prevention strategies regarding alcohol and drug use and related harms is indicated by the findings. PMID:24139778

    Boxing involves a high risk of dental trauma due to the impact of enormous external forces against the head. Wearing a mouthguard is, therefore, mandatory. The aim of this study was to evaluate the prevalence of dental trauma as well as the utilization and quality of mouthguards in Swiss boxing clubs. In order to achieve this, data on the mouthguards of 217 boxers in total were collected using questionnaires and examination forms, which were statistically evaluated. Out of the 217 boxers, 75 (34.6%) had already experienced a dental accident, but only 8 (10.7%) of them while practicing their sport. Professional boxers were most frequently affected by dental trauma (p = 0.001). Crown fractures were most often observed, followed by tooth dislocations. All interviewed athletes owned a mouthguard, which they used much more consistently during full-contact sparring (practice fighting) than during regular partner exercises. Most of the boxers used prefabricated mouthguards, which could be individually adapted using the “boil and bite” system. The majority of the athletes received their mouthguards from the boxing club. Impaired speaking when wearing a mouthguard was, by far, the problem most frequently mentioned by the athletes. In terms of these bothering factors, custom-made mouthguards from dentists received the best rating (p = 0.002). The quality of the mouthguard was assessed by evaluating the following criteria: coverage of the buccolabial surface, occlusal support of the opposing dentition, thickness of the occlusal layer, and rounded edges. Of the 215 mouthguards examined, 193 (89.8%) were insufficient (p = 0.002). Despite the observed deficiencies, only a few dental injuries occurred during boxing. This study shows that although basic preventive measures do exist in Swiss boxing, they should be improved substantially by providing better instruction and more information. PMID:26678302

    Interfacial joining (bonding) is a widely accepted welding process and one of the environmentally benign technologies used in industrial production. As the bonding temperature is lower than the melting point of the parent materials, melting of the latter is kept to a minimum. The process can be based on diffusion bonding, pressure welding, friction welding, ultrasonic bonding, or brazing-soldering, all of which offer many advantages over fusion welding. In addition, surface technologies such as surface modification, spraying, coating, plating, and thin-film formation are necessary for advanced manufacturing, fabrication, and electronics packaging. Together, interfacial joining and surface technology (IJST) will continue to be used in various industrial fields because IJST is a very significant form of environmentally conscious materials processing. The international symposium of IJST 2013 was held at Icho Kaikan, Osaka University, Japan from 27-29 November, 2013. A total of 138 participants came from around the world to attend 56 oral presentations and 36 posters presented at the symposium, and to discuss the latest research and developments on interfacial joining and surface technologies. This symposium was also held to commemorate the 30th anniversary of the Technical Commission on Interfacial Joining of the Japan Welding Society. On behalf of the chair of the symposium, it is my great pleasure to present this volume of IOP Conference Series: Materials Science and Engineering (MSE). Among the presentations, 43 papers are published here, and I believe all of the papers have provided the welding community with much useful information. I would like to thank the authors for their enthusiastic and excellent contributions. Finally, I would like to thank all members of the committees, secretariats, participants, and everyone who contributed to this symposium through their support and invaluable effort for the success of IJST 2013.

  16. Nonlinear Aeroelastic Analysis of Joined-Wing Configurations

    NASA Astrophysics Data System (ADS)

    Cavallaro, Rauno

    Aeroelastic design of joined-wing configurations is yet a relatively unexplored topic which poses several difficulties. Due to the overconstrained nature of the system combined with structural geometric nonlinearities, the behavior of Joined Wings is often counterintuitive and presents challenges not seen in standard layouts. In particular, instability observed on detailed aircraft models but never thoroughly investigated, is here studied with the aid of a theoretical/computational framework. Snap-type of instabilities are shown for both pure structural and aeroelastic cases. The concept of snap-divergence is introduced to clearly identify the true aeroelastic instability, as opposed to the usual aeroelastic divergence evaluated through eigenvalue approach. Multi-stable regions and isola-type of bifurcations are possible characterizations of the nonlinear response of Joined Wings, and may lead to branch-jumping phenomena well below nominal critical load condition. Within this picture, sensitivity to (unavoidable) manufacturing defects could have potential catastrophic effects. The phenomena studied in this work suggest that the design process for Joined Wings needs to be revisited and should focus, when instability is concerned, on nonlinear post-critical analysis since linear methods may provide wrong trend indications and also hide potentially catastrophical situations. Dynamic aeroelastic analyses are also performed. Flutter occurrence is critically analyzed with frequency and time-domain capabilities. Sensitivity to different-fidelity aeroelastic modeling (fluid-structure interface algorithm, aerodynamic solvers) is assessed showing that, for some configurations, wake modeling (rigid versus free) has a strong impact on the results. Post-flutter regimes are also explored. Limit cycle oscillations are observed, followed, in some cases, by flip bifurcations (period doubling) and loss of periodicity of the solution. Aeroelastic analyses are then carried out on a

    The gene encoding DNA polymerase θ (Polθ) was discovered over ten years ago as having a role in suppressing genome instability in mammalian cells. Studies have now clearly documented an essential function for this unique A-family polymerase in the double-strand break (DSB) repair pathway alternative end-joining (alt-EJ), also known as microhomology-mediated end-joining (MMEJ), in metazoans. Biochemical and cellular studies show that Polθ exhibits a unique ability to perform alt-EJ and during this process the polymerase generates insertion mutations due to its robust terminal transferase activity which involves template-dependent and independent modes of DNA synthesis. Intriguingly, the POLQ gene also encodes for a conserved superfamily 2 Hel308-type ATP-dependent helicase domain which likely assists in alt-EJ and was reported to suppress homologous recombination (HR) via its anti-recombinase activity. Here, we review our current knowledge of Polθ-mediated end-joining, the specific activities of the polymerase and helicase domains, and put into perspective how this multifunctional enzyme promotes alt-EJ repair of DSBs formed during S and G2 cell cycle phases.

    Recently there has been a great deal of interest in research development and commercialization of solid oxide fuel cells (SOFCs). Joining and sealing are critical issues that will need to be addressed before SOFCs can truly perform as expected. Ceramics and metals can be difficult to join together, especially when the joint must withstand up to 900 C operating temperature of the SOFCs. The goal of the present study is to find the most suitable braze material for joining of yttria stabilized zirconia (YSZ) to stainless steel. A number of commercially available braze materials TiCuSil, TiCuNi, Copper-ABA, Gold-ABA and Gold-ABA-V have been evaluated. The oxidation behavior of the braze materials and steel substrates in air was also examined through thermogravimetric analysis. The microstructure and composition of the brazed regions have been examined by optical and scanning electron microscopy and eDS analysis. Effect of braze composition and processing conditions on the interfacial microstructure and composition of the joint regions will be presented.

    Padmanabham, G.; Shanmugarajan, B.

    Laser as a high intensity heat source can be effectively used for joining of materials by fusion welding and brazing in autogenous or in hybrid modes. In autogenous mode, welding is done in conduction , deep penetration , and keyhole mode. However, due to inherently high energy density available from a laser source, autogenous keyhole welding is the most popular laser welding mode. But, it has certain limitations like need for extremely good joint fit-up, formation of very hard welds in steel , keyhole instability, loss of alloying elements, etc. To overcome these limitations, innovative variants such as laser-arc hybrid welding , induction-assisted welding , dual beam welding , etc., have been developed. Using laser heat, brazing can be performed by melting a filler to fill the joints, without melting the base materials. Accomplishing laser-based joining as mentioned above requires appropriate choice of laser source, beam delivery system, processing head with appropriate optics and accessories. Basic principles of various laser-based joining processes, laser system technology, process parameters, metallurgical effects on different base materials, joint performance, and applications are explained in this chapter.

    Lustre is a parallel file system that presents high aggregated IO bandwidth by striping file extents across many storage devices. However, our experiments indicate excessively wide striping can cause performance degradation. Lustre supports an innovative file joining feature that joins files in place. To mitigate striping overhead and benefit collective IO, we propose two techniques: split writing and hierarchical striping. In split writing, a file is created as separate subfiles, each of which is striped to only a few storage devices. They are joined as a single file at the file close time. Hierarchical striping builds on top of split writing and orchestrates the span of subfiles in a hierarchical manner to avoid overlapping and achieve the appropriate coverage of storage devices. Together, these techniques can avoid the overhead associated with large stripe width, while still being able to combine bandwidth available from many storage devices. We have prototyped these techniques in the ROMIO implementation of MPI-IO. Experimental results indicate that split writing and hierarchical striping can significantly improve the performance of Lustre collective IO in terms of both data transfer and management operations. On a Lustre file system configured with 46 object storage targets, our implementation improves collective write performance of a 16-process job by as much as 220%.

    Demanding design requirements frequently call for the use and joining of combinations of oxide and nonoxide ceramics, intermetallics, and metals in virtually every imaginable combination in both monolithic and reinforced forms, resulting in hybrid structures. Such new, nontraditional materials and structures can be expected to require new, nontraditional joining processes. One attractive, but embryonic option, is pressurized combustion synthesis, a form of exothermic welding or brazing. Pressurized combustion synthesis or self-propagating high-temperature synthesis (SHS) joining is being systematically studied to understand the mechanism(s) of joint formation, understand the role of processing parameters, evaluate and optimize joint properties, and develop a process model for use in joint design, parameter selection, property prediction, and intelligent process control. This paper presents the results of a study on a model system of 3Ni + Al > Ni{sub 3}Al filler or intermediate between nickel-base superalloy end elements. A Gleeble thermal-mechanical simulator was used to investigate the effects of reaction temperature, hold time, applied pressure, reactant composition, and heating rate, and good insight has been gained to enable more intensive studies of process fundamentals and of techniques for producing more complex, functional gradient material (FGM) joints between dissimilar combinations of ceramics, intermetallics and metals.

    The future use of the CERN SPS accelerator as injector for the Large Hadron Collider, LHC, and the possible use of the SPS as a neutrino source for the Gran Sasso experiment are pushing the maximum intensity requirements of the accelerator much higher than achieved up to now. At the same time the requirements on beam quality are becoming far more stringent. The SPS machine, built in the 70's, is not a "smooth" machine. It contains many discontinuities in vacuum chamber cross-section and many cavity-like objects, as well as the 5 separate RF systems at present installed. All these lead to a high impedance, seen by the beam, spread over a wide frequency range. As a result there is a constant fight against instabilities, both single and multi bunch, as the intensity increases. A program of studies is under way in the SPS to identify, reduce, and remove where possible the sources of these impedances.

    This paper briefly introduces the data acquisition system of the COMPASS experiment and is mainly focused on the part that is responsible for the monitoring of the nodes in the whole newly developed data acquisition system of this experiment. The COMPASS is a high energy particle experiment with a fixed target located at the SPS of the CERN laboratory in Geneva, Switzerland. The hardware of the data acquisition system has been upgraded to use FPGA cards that are responsible for data multiplexing and event building. The software counterpart of the system includes several processes deployed in heterogenous network environment. There are two processes, namely Message Logger and Message Browser, taking care of monitoring. These tools handle messages generated by nodes in the system. While Message Logger collects and saves messages to the database, the Message Browser serves as a graphical interface over the database containing these messages. For better performance, certain database optimizations have been used. Lastly, results of performance tests are presented.

He was involved in three important, emerging technologies, radar, particle accelerators and controlled fusion, and had an outstanding impact on the last two. Without a university education, he attained hierarchical positions of the highest level in prestigious national and international organizations. This article covers the CERN part of his career, by offering some personal insights into the different facets of his contributions to major accelerator projects, from the first strong-focusing synchrotron, the PS, to the SPS and its conversion to a proton--antiproton collider. In particular, it outlines his abilities as a leader of an international collaboration, which has served as an example for international initiatives in other disciplines.

    The report presents the cellular structure of the respiratory system as well as the history of club cells (Clara cells), their ultrastructure, and location in the airways and human organs. The authors discuss the biochemical structure of proteins secreted by these cells and their importance for the integrity and regeneration of the airway epithelium. Their role as progenitor cells for the airway epithelium and their involvement in the biotransformation of toxic xenobiotics introduced into the lungs during breathing is emphasized. This is followed by a discussion of the clinical aspects associated with club cells, demonstrating that tracking the serum concentration of club cell-secreted proteins is helpful in the diagnosis of a number of lung tissue diseases. Finally, suggestions are provided regarding the possible use of proteins secreted by club cells in the treatment of serious respiratory conditions. PMID:27212975

    Objective. To determine pharmacy students’ attitudes and academic performance related to journal club during 2 advanced pharmacy practice experiences (APPEs). Design. Fourth-year pharmacy students were required to complete 3 journal club assignments during drug information and internal medicine APPEs. Assessment. A majority (91.3%) of the 105 students who responded to a 21-item survey instrument indicated that journal club assignments during the drug-information APPE were valuable to their understanding of research design and statistics. Students who completed the drug-information APPE before the internal medicine APPE scored higher on their understanding of the strengths and weaknesses and the clinical relevance of studies and had a higher learning slope (p = 0.01) than did students who completed the internal medicine APPE first. Conclusion. Incorporating journal clubs into APPEs is an effective means of teaching literature-evaluation skills to pharmacy students. PMID:22761529

    Young, Richard W

    2003-01-01

    It has been proposed that the hominid lineage began when a group of chimpanzee-like apes began to throw rocks and swing clubs at adversaries, and that this behaviour yielded reproductive advantages for millions of years, driving natural selection for improved throwing and clubbing prowess. This assertion leads to the prediction that the human hand should be adapted for throwing and clubbing, a topic that is explored in the following report. It is shown that the two fundamental human handgrips, first identified by J. R. Napier, and named by him the ‘precision grip’ and ‘power grip’, represent a throwing grip and a clubbing grip, thereby providing an evolutionary explanation for the two unique grips, and the extensive anatomical remodelling of the hand that made them possible. These results are supported by palaeoanthropological evidence. PMID:12587931

    Professional association football is a game of talent. The success of a professional club hinges largely on its ability of assembling the best team. Building on a dataset of player transfer records among more than 400 clubs in 24 world-wide top class leagues from 2011 to 2015, this study aims to relate a club's success to its activities in the player transfer market from a network perspective. We confirm that modern professional football is indeed a money game, in which larger investment spent on the acquisition of talented players generally yields better team performance. However, further investigation shows that professional football clubs can actually play different strategies in surviving or even excelling this game, and the success of strategies is strongly associated to their network properties in the football player transfer network.

    Fish in the Superorder Ostariophysi possess large epidermal club cells that release chemical cues warning nearby conspecifics of danger. Despite the long-held assumption that such club cells evolved under the selective force of predation, recent studies demonstrated that predation has no effect on club cell investment. Rather, club cells have an immune function and cell production may be stimulated by skin-penetrating pathogens and parasites. The current work investigates whether fathead minnows, Pimephales promelas, alter their club cell characteristics based on variation in infection risk. In a 2 × 3 design, we exposed minnows to infective cysts of two oomycete species (Saprolegnia ferax and S. parasitica) at three different concentrations (2, 20 or 200 cysts L(-1)). Club cell characteristics (number and size) were quantified 12 days after exposure. Saprolegnia parasitica is thought to be more pathogenic than S. ferax, hence we predicted greater club cell investment and a larger turnover rate of cells by minnows exposed to S. parasitica than S. ferax. We also predicted that minnows exposed to higher numbers of cysts should invest more in club cells and have a higher turnover rate of cells. We found no difference in club cell density or size between fish exposed to the two Saprolegnia species; however, fish exposed to high concentrations of pathogens had smaller club cells than those exposed to low concentrations, indicating a higher rate of turnover of cells in the epidermis.

    Background Journal clubs are an essential tool in promoting clinical evidence-based medical education to all medical and allied health professionals. Twitter represents a public, microblogging forum that can facilitate traditional journal club requirements, while also reaching a global audience, and participation for discussion with study authors and colleagues. Objective The aim of the current study was to evaluate the current state of social media–facilitated journal clubs, specifically Twitter, as an example of continuing professional development. Methods A systematic review of literature databases (Medline, Embase, CINAHL, Web of Science, ERIC via ProQuest) was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A systematic search of Twitter, the followers of identified journal clubs, and Symplur was also performed. Demographic and monthly tweet data were extracted from Twitter and Symplur. All manuscripts related to Twitter-based journal clubs were included. Statistical analyses were performed in MS Excel and STATA. Results From a total of 469 citations, 11 manuscripts were included and referred to five Twitter-based journal clubs (#ALiEMJC, #BlueJC, #ebnjc, #urojc, #meded). A Twitter-based journal club search yielded 34 potential hashtags/accounts, of which 24 were included in the final analysis. The median duration of activity was 11.75 (interquartile range [IQR] 19.9, SD 10.9) months, with 7 now inactive. The median number of followers and participants was 374 (IQR 574) and 157 (IQR 272), respectively. An overall increasing establishment of active Twitter-based journal clubs was observed, resulting in an exponential increase in total cumulative tweets (R 2=.98), and tweets per month (R 2=.72). Cumulative tweets for specific journal clubs increased linearly, with @ADC_JC, @EBNursingBMJ, @igsjc, @iurojc, and @NephJC, and showing greatest rate of change, as well as total impressions per month since

    Recent studies using Magnetic Resonance Imaging (MRI) have proposed that the brain's white matter is organized as a rich club, whereby the most highly connected regions of the brain are also highly connected to each other. Here we use both functional and diffusion-weighted MRI in the human brain to investigate whether the rich club phenomena is present with functional connectivity, and how this organization relates to the structural phenomena. We also examine whether rich club regions serve to integrate information between distinct brain systems, and conclude with a brief investigation of the developmental trajectory of rich-club phenomena. In agreement with prior work, both adults and children showed robust structural rich club organization, comprising regions of the superior medial frontal/dACC, medial parietal/PCC, insula, and inferior temporal cortex. We also show that these regions were highly integrated across the brain's major networks. Functional brain networks were found to have rich club phenomena in a similar spatial layout, but a high level of segregation between systems. While no significant differences between adults and children were found structurally, adults showed significantly greater functional rich club organization. This difference appeared to be driven by a specific set of connections between superior parietal, insula, and supramarginal cortex. In sum, this work highlights the existence of both a structural and functional rich club in adult and child populations with some functional changes over development. It also offers a potential target in examining atypical network organization in common developmental brain disorders, such as ADHD and Autism.

    Background/Aims The present study is the first to prospectively compare a group of recreational Ecstasy users when dance clubbing on 3,4-methylenedioxymethamphetamine (MDMA) and when clubbing during abstinence from Ecstasy/MDMA. Methods Twelve normal healthy volunteers (mean age = 23.2 years) were assessed at a Saturday night dance club under self-administered MDMA. On the other weekend they went to the same dance club without taking MDMA (order counterbalanced). Both conditions involved 5 test sessions conducted at similar times: pre-drug baseline, 1 h post-drug clubbing, 2.5 h post-drug clubbing, and 2 and 4 days later. The assessments included body and ambient temperature, physical activity (pedometer), as well as self-ratings for mood state, physical activity, thermal comfort and thirst. Saliva samples were analyzed for MDMA, cortisol and testosterone. Results The cortisol levels increased significantly by 800% when dance clubbing on MDMA, while testosterone increased significantly by 75%; neither neuroendocrine measure was altered during abstinence. Saliva analyses confirmed the presence of MDMA when dancing on Ecstasy and its absence when dancing off Ecstasy. The pedometer values and self-rated levels of dancing were similar at both weekends. Hot and cold flushes and feeling hot increased significantly under MDMA. The mean body temperature did not change significantly, although there was a borderline trend for increased values after MDMA. Feelings of happiness and excitement increased under MDMA, although they were not significantly greater than when clubbing during abstinence. Conclusions Neurohormonal release may be an important part of the acute MDMA experience. The large cortisol increase provides further data on the bioenergetic stress model of recreational Ecstasy/MDMA. PMID:18654086

    The UK waste strategy is based upon use of the best practicable environmental option (BPEO), by those making waste management decisions. BPEO is supported by the use of the waste hierarchy, with its range of preferable options for dealing with waste, and the proximity principle, where waste is treated/disposed of as close to its point of origin as possible. The national waste strategy emphasizes the key role of waste minimization and encourages industry, commerce and the public to move towards sustainable waste management practice for economic and environmental reasons. Waste minimization clubs have been used, since the early 1990s, to demonstrate to industry/commerce that reducing waste production can lead to significant financial savings. There have been around 75 such clubs in the UK and they receive support from a wide range of agencies, including the Environmental Technology Best Practice Program. The early Demonstration Clubs had significant savings to cost ratios, e.g. Aire and Calder at 8.4, but had very high costs, e.g. Aire and Calder at 400,000 pounds. It is acknowledged that the number of clubs will have to be approximately doubled in the next few years so as to have an adequate coverage of the UK. There are at present, marked regional variations in club development and cognizance needs to be taken, by facilitators, of the need for extensive coverage of the UK. Future clubs will probably have to operate in a financially constrained climate and they need to be designed to deliver significant savings and waste reduction at low cost. To aid future club design, final reports of all projects should report in a standard manner so that cost benefit analysis can be used to inform facilitators about the most effective club type. rights reserved.

    Systems and methods for joining BMG Composites are disclosed. Specifically, the joining of BMG Composites is implemented so as to preserve the amorphicity of their matrix phase and the microstructure of their particulate phase. Implementation of the joining method with respect to the construction of modular cellular structures that comprise BMG Composites is also discussed.
