  19. Scientists and Educators: Joining Forces to Enhance Ocean Science Literacy

    NASA Astrophysics Data System (ADS)

    Keener-Chavis, P.

    2004-12-01

    The need for scientists to work with educators to enhance the general public's understanding of science has been addressed for years in reports like Science for All Americans (1990), NSF in a Changing World (1995), Turning to the Sea: America's Ocean Future (1999), Discovering the Earth's Final Frontier, A U.S. Strategy for Ocean Exploration (2000), and most recently, the U.S. Commission on Ocean Policy Report (2004). As reported in The National Science Foundation's Center for Ocean Science Education Excellence (COSEE) Workshop Report (2000), "The Ocean Sciences community did not answer (this) call, even though their discovery that the ocean was a more critical driving force in the natural environment than previously thought possessed great educational significance." It has been further acknowledged that "rapid and extensive improvement of science education is unlikely to occur until it becomes clear to scientists that they have an obligation to become involved in elementary- and secondary-level science (The Role of Scientists in the Professional Development of Science Teachers, National Research Council, 1996.) This presentation will focus on teachers' perceptions of how scientists conduct research, scientists' perceptions of how teachers should teach, and some misconceptions between the two groups. Criteria for high-quality professional development for teachers working with scientists will also be presented, along with a brief overview of the National Oceanic and Atmospheric Administration's Ocean Exploration program efforts to bring teachers and ocean scientists together to further ocean science literacy at the national level through recommendations put forth in the U.S. Commission on Ocean Policy Report (2004).

    2013-11-01

    Many young people who are mistreated by an adult, victimized by bullies, criminally assaulted, or who witness domestic violence react to this violence exposure by developing behavioral, emotional, or learning problems. What is less well known is that adverse experiences like violence exposure can lead to hidden physical alterations inside a child's body, alterations that may have adverse effects on life-long health. We discuss why this is important for the field of developmental psychopathology and for society, and we recommend that stress-biology research and intervention science join forces to tackle the problem. We examine the evidence base in relation to stress-sensitive measures for the body (inflammatory reactions, telomere erosion, epigenetic methylation, and gene expression) and brain (mental disorders, neuroimaging, and neuropsychological testing). We also review promising interventions for families, couples, and children that have been designed to reduce the effects of childhood violence exposure. We invite intervention scientists and stress-biology researchers to collaborate in adding stress-biology measures to randomized clinical trials of interventions intended to reduce effects of violence exposure and other traumas on young people.

  17. Librarians and Scientists: Combining Forces for Better Metrics

    NASA Astrophysics Data System (ADS)

    Rots, Arnold H.; Winkelman, Sherry

    2015-08-01

    Traditionally, observatory bibliographies mainly rely on two parameters derived from the carefully compiled lists of publications associated, in a well-defined way, with the observatories contribution to the advancement of science: numbers of articles and numbers of citations - in addition to the bibliographic metadata relating to those articles. The information that can be extracted from metrics based on these parameters is limited. This is a realization that is not just typical to astronomy and astrophysics, but one that is felt across many disciplines.Relating articles with very specific datasets allows us to join those datasets' metadata with the bibliographic metadata which opens a much richer field of information to mine for knowledge concerning the performance, not only of the observatory as a whole, but also its parts: instruments, types of observations, length of observations, etc. We have experimented extensively with such new metrics in the Chandra Data Archive in the Chandra X-ray Center at SAO.The linking of articles with individual datasets requires a level of scientific expertise that is usually not in the, otherwise extensive, skill set of the librarians, but is something that is crucial on the road to more informative bibliographic metrics.This talk is a plea for librarians and research scientists to join forces to make this happen. The added benefit of such a collaboration is a powerful research tool for navigating data and literature through a single interface.This work has been supported by NASA under contract NAS 8-03060 to the Smithsonian Astrophysical Observatory for operation of the Chandra X-ray Center. It depends critically on the services provided by the ADS, which is funded by NASA Grant NNX12AG54G.

    In recent years, the use of aluminum alloy has tended to increase for building lightweight automobiles to reduce their automotive weight, which is helpful to save energy and protect the environment. In order to join aluminum alloy, a flat-clinching process combined with material forming technology was investigated to join aluminum alloy sheets using an experimental and a numerical method. Al1060 was chosen as the material of the sheet, and DEFORM-2D software was used to build the numerical model. After the numerical model was validated by the experimental results, the influences of punch diameter and holder force on the materials deforming behavior of the clinched joint were analyzed using the numerical model. Then, the material flow, joining ability, and joining quality were investigated to assess the clinched joint. The results showed that an increase in punch diameter could give rise to an increase in neck thickness and interlocking length, while an increase in blank holder force induced a decrease in interlocking length and an increase in neck thickness. The joining quality could be increased by increasing the forming force. It can be concluded that a clinched joint has better joining quality for joining light-weight sheets onto automotive structures.

  14. Increasing FSW join strength by optimizing feed rate, rotating speed and pin angle

    NASA Astrophysics Data System (ADS)

    Darmadi, Djarot B.; Purnowidodo, Anindito; Siswanto, Eko

    2017-10-01

    Principally the join in Friction Stir Welding (FSW) is formed due to mechanical bonding. At least there are two factors determines the quality of this join, first is the temperature in the area around the interface and secondly the intense of mixing forces in nugget zone to create the mechanical bonding. The adequate temperature creates good flowability of the nugget zone and an intensive mixing force produces homogeneous strong bonding. Based on those two factors in this research the effects of feed rate, rotating speed and pin angle of the FSW process to the tensile strength of resulted join are studied. The true experimental method was used. Feed rate was varied at 24, 42, 55 and 74 mm/minutes and from the experimental results, it can be concluded that the higher feed rate decreases the tensile strength of weld join and it is believed due to the lower heat embedded in the material. Inversely, the higher rotating speed increases the join’s tensile strength as a result of higher heat embedded in base metal and higher mixing force in the nugget zone. The rotating speed were 1842, 2257 and 2904 RPMs. The pin angle determines the direction of mixing force. With variation of pin angle: 0°, 4°, 8° and 12° the higher pin angle generally increases the tensile strength because of more intensive mixing force. For 12° pin angle the lower tensile strength is found since the force tends to push out the nugget area from the joint gap.

    An approach utilizing low energy N ion beam irradiation is applied in joining two monolayer graphene flakes. Raman spectrometry and atomic force microscopy show the joining signal under 40 eV and 1 × 1014 cm-2 N ion irradiation. Molecular dynamics simulations demonstrate that the joining phenomenon is attributed to the punch-down effect and the subsequent chemical bond generation between the two sheets. The generated chemical bonds are made up of inserted ions (embedded joining) and knocked-out carbon atoms (saturation joining). The electronic transport properties of the joint are also calculated for its applications.

The following comments about SESAME were made by this board: ``a quintessential UNESCO project combining capacity building with vital peace-building through science'' and ``a model project for other regions.'' Now that SESAME is well underway, other regions (e.g.; Africa and Central Asia) should be made aware of this progress, and they should be welcomed to join SESAME as a first step in developing similar projects in their region. Students and scientists from other regions should be encouraged to attend SESAME Users' meeting, schools, workshops, etc. where they can learn about synchrotron radiation sources, beamlines, and science. They should be invited to join SESAME scientists in designing and commissioning accelerators and beamlines, gaining relevant experience for their own projects and helping SESAME in the process.

    2018-05-01

    With the demand of lightweight design in the automotive industry, not only the wall-thicknesses of tubular components of the chassis or spaceframe are continuously decreased. Also the thicknesses of exhaust system parts are reduced to save material and mass. However, thinner tubular parts bring about additional challenges in joining. Welding or brazing methods, which are utilized in joining tubes with specific requirements concerning leak tightness, are sensitive to the gap between the joining partners. Furthermore, a large joining area is required to ensure the durability of the joint. The introduction of a forming step in the assembled state prior to thermal joining can define and control the gap for subsequent brazing or welding. The mechanical pre-joint resulting from the previously described calibration step also results in easier handling of the tubes prior to thermal joining. In the presented investigation, a spinning process is utilized to produce force-fit joints of varying lengths and diameter reduction and form-fit joints with varying geometrical attributes. The spinning process facilitates a high formability and geometrical flexibility, while at the achievable precision is high and the process forces are low. The strength of the joints is used to evaluate the joint quality. Finally, a comparison between joints produced by forming with subsequent brazing and original tube is conducted, which presents the high performance of the developed procedure for forming assisted thermal joining.

    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.

    DOE PAGES

    2016-04-25

    Primary radiation damage formation in solid materials typically involves collisions between atoms that have up to a few hundred keV of kinetic energy. The distance between two colliding atoms can approach 0.05 nm during these collisions. At such small atomic separations, force fields fitted to equilibrium properties tend to significantly underestimate the potential energy of the colliding dimer. To enable molecular dynamics simulations of high-energy collisions, it is common practice to use a screened Coulomb force field to describe the interactions and to smoothly join this to the equilibrium force field at a suitable interatomic spacing. But, there is nomore » accepted standard method for choosing the parameters used in the joining process, and our results prove that defect production is sensitive to how the force fields are linked. A new procedure is presented that involves the use of ab initio calculations to determine the magnitude and spatial dependence of the pair interactions at intermediate distances, along with systematic criteria for choosing the joining parameters. Results are presented for the case of nickel, which demonstrate the use and validity of the procedure.« less

    The study examines the labor-force behavior of Israelis at older ages, focusing on the determinants of the transitions between states of labor-force participation between 2005 and 2010. The study uses panel data from the first two waves of the SHARE-Israel longitudinal survey. A multinomial logit model is used to examine the impact of sociodemographic characteristics, health state, and economic resources on labor-force transitions of people aged 50-67. The results emphasize the role of age and poor health in "pushing" older people out of the labor force or "keeping" them there. Spouse's participation is found to encourage individuals to leave the labor force or to refrain from joining it. However, living with a participating spouse is negatively associated with staying out of the labor force, consistent with the dominance of the complementarity of leisure effect found in the literature. Wealth as an economic resource available to individuals for retirement is also found to encourage individuals to leave the labor force or to refrain from joining it.

  8. When do scientists become entrepreneurs? The social structural antecedents of commercial activity in the academic life sciences.

    PubMed

    Stuart, Toby E; Ding, Waverly W

    2006-07-01

    The authors examine the conditions prompting university-employed life scientists to become entrepreneurs, defined to occur when a scientist (1) founds a biotechnology company, or (2) joins the scientific advisory board of a new biotechnology firm. This study draws on theories of social influence, socialization, and status dynamics to examine how proximity to colleagues in commercial science influences individuals' propensity to transition to entrepreneurship. To expose the mechanisms at work, this study also assesses how proximity effects change over time as for-profit science diffuses through the academy. Using adjusted proportional hazards models to analyze case-cohort data, the authors find evidence that the orientation toward commercial science of individuals' colleagues and coauthors, as well as a number of other workplace attributes, significantly influences scientists' hazards of transitioning to for-profit science.

  9. Ultrapulse welding: A new joining technique. [for automotive industry

    NASA Technical Reports Server (NTRS)

    Anderson, D. G.

    1972-01-01

    The ultrapulse process is a resistance welding process that utilizes unidirectional current of high magnitude for a very short time with a precisely controlled dynamic force pulse. Peak currents of up to 220,000 amperes for two to ten milliseconds are used with synchronized force pulses of up to nine thousand pounds. The welding current passing through the relatively high resistance of the interface between the parts that are being joined results in highly localized heating. Described is the UPW process as it applies to the automotive industry.

  13. Self-force as a probe of global structure

    NASA Astrophysics Data System (ADS)

    Davidson, Karl; Poisson, Eric

    2018-05-01

    We calculate the self-force on an electric charge and electric dipole held at rest in a closed universe that results from joining two copies of Minkowski spacetime at a common boundary. Spacetime is strictly flat on each side of the boundary, but there is curvature at the surface layer required to join the two Minkowski spacetimes. We find that the self-force on the charge is always directed away from the surface layer. This is analogous to the case of an electric charge held at rest inside a spherical shell of matter, for which the self-force is also directed away from the shell. For the dipole, the direction of the self-force is a function of the dipole's position and orientation. Both self-forces become infinite when the charge or dipole is made to approach the surface layer. This study reveals that a self-force can arise even when the Riemann tensor vanishes at the position of the charge or dipole; in such cases the self-force is a manifestation of the global curvature of spacetime.

  14. Influence of clamp-up force on the strength of bolted composite joints

    NASA Astrophysics Data System (ADS)

    Horn, Walter J.; Schmitt, Ron R.

    1994-03-01

    Composite materials offer the potential for a reduction in the number of individual parts and joints in a structure because large one-piece components can replace multipart assemblies. Nevertheless, there are many situations where composite parts must be joined and often mechanical fasteners provide the only practical method of joining those parts. The long-term strength of mechanically fastened joints of composite members can be directly affected by the clamp-up force of the fastener and thus perhaps by the relaxation of this force due to the viscoelastic character of the composite materials of the joint. Methods for predicting the effect of bolt clamp-up force relaxation on the strength of mechanically fastened joints of thermoplastic composite materials were investigated during the present study. A test program, using two thermoplastic composite materials, was conducted to determine the influence of clamp-up force on joint strength, to measure the relaxation of the joint clamp-up force with time, and to measure the change of joint strength as a function of time.

    The Answers in Genesis Creation Museum opened in May of 2007. During the opening day, a loosely affiliated group of scientists joined in a Rally for Reason as they termed it to protest the museum's potential effect on science in the United States. This paper discusses ethnographic data collected before and during the rally. Scientist narratives disclose the rationale for their participation at the rally, unpacking their hopes, fears and social ideals vis-à-vis their perception of the Museum's impact. With these ideals, I discuss the lacking discourse between the values of ideal of science literacy, the contested authority of museums and their publics, and a lacking conception of how a valuerationality aligned towards the Museum's message continues to be culturally produced.

    This year marks the fourth annual Geosciences Congressional Visits Day (Geo-CVD), in which scientists from across the nation join together in Washington, D. C., to meet with their legislators to discuss the importance of funding for Earth and space sciences. AGU partnered with seven other Earth and space science organizations to bring more than 50 scientists, representing 23 states, for 2 days of training and congressional visits on 20-21 September 2011. As budget negotiations envelop Congress, which must find ways to agree on fiscal year (FY) 2012 budgets and reduce the deficit by $1.5 trillion over the next 10 years, Geo-CVD scientists seized the occasion to emphasize the importance of federally funded scientific research as well as science, technology, engineering, and math (STEM) education. Cuts to basic research and STEM education could adversely affect innovation, stifle future economic growth and competitiveness, and jeopardize national security.

This never-before-seen feature looks like a pair of bubbles extending above and below our galaxy's center. But these enormous gamma-ray emitting lobes aren't immediately visible in the Fermi all-sky map. However, by processing the data, a group of scientists was able to bring these unexpected structures into sharp relief. Each lobe is 25,000 light-years tall and the whole structure may be only a few million years old. Within the bubbles, extremely energetic electrons are interacting with lower-energy light to create gamma rays, but right now, no one knows the source of these electrons. Are the bubbles remnants of a massive burst of star formation? Leftovers from an eruption by the supermassive black hole at our galaxy's center? Or or did these forces work in tandem to produce them? Scientists aren't sure yet, but the more they learn about this amazing structure, the better we'll understand the Milky Way.

  4. Joseph Rotblat: Moral Dilemmas and the Manhattan Project

    NASA Astrophysics Data System (ADS)

    John Fitzgerald Kennedy famously said, "One man can make a difference and every man should try."1 Joseph Rotblat (1908-2005) was the quintessence of Kennedy's conviction. He was the only scientist who left Los Alamos after it transpired that the atomic bomb being developed there was intended for use against adversaries other than Nazi Germany. I explore Rotblat's early research in Warsaw and Liverpool, which established his reputation as a highly capable experimental physicist, and which led him to join the Manhattan Project at Los Alamos in 1944. I examine his motivation for resigning from the project in 1945, and the unwillingness of his fellow scientists to follow suit, which draws attention to the continuing discourse on the responsibility of scientists for the consequences of their research.

    Carbon fiber reinforced polymer (CFRP) has been recently applied to not only wing, but also fan blades of turbo fan engines. To prevent impact force, leading edge of titanium was often mounted on the CFRP fan blades with adhesive force. In order to enhance the joining strength, a joining method with carbon fiber reinforced interface has been developed. By using nickel-coated carbon fibers, a joining sample with carbon fiber-reinforced interface between CFRP and CFRM has been successfully developed. The joining sample with nickel-coated carbon fiber interface exhibits the high tensile strength, which was about 10 times higher than that with conventional adhesion. On the other hand, Al-welding methods to steel, Cu and Ti with carbon fiber reinforced interface have been successfully developed to lighten the parts of machines of racing car and airplane. Carbon fibers in felt are covered with metals to protect the interfacial reaction. The first step of the welding method is that the Al coated felt is contacted and wrapped with molten aluminum solidified under gravity pressure, whereas the second step is that the felt with double layer of Ni and Al is contacted and wrapped with molten steel (Cu or Ti) solidified under gravity pressure. Tensile strength of Al-Fe (Cu or Ti) welded sample with carbon fiber reinforced interface is higher than those of Al-Fe (Cu or Ti) welded sample.

    2002-11-01

    Towards a comprehensive aeroelastic analysis of a joined wing, fluid dynamics and structural analyses are initially performed separately. Steady flow calculations are currently performed using 3-D compressible Navier-Stokes equations. Flow analysis of M6-Onera wing served to validate the software for the fluid dynamics analysis. The complex flow field of the joined wing is analyzed and the prevailing fluid dynamic forces are computed using COBALT software. Currently, these forces are being transferred as fluid loads on the structure. For the structural analysis, several test cases were run considering the wing as a cantilever beam; these served as validation cases. A nonlinear structural analysis of the wing is being performed using ANSYS software to predict the deflections and stresses on the joined wing. Issues related to modeling, and selecting appropriate mesh for the structure were addressed by first performing a linear analysis. The frequencies and mode shapes of the deformed wing are obtained from modal analysis. Both static and dynamic analyses are carried out, and the results obtained are carefully analyzed. Loose coupling between the fluid and structural analyses is currently being examined.

    2012-01-18

    In the field of nanoscience, if you can control how nanoparticles self-assemble in particular structures — joining each other, for example, as molecules can form, atom-by-atom — you can design new materials that have unique properties that industry needs. Nature already uses the DNA genetic code to instruct the building of specific proteins and whole organisms in both plants and people. Taking a cue from nature, scientists at BNL devised a way of using strands of synthetic DNA attached to the surface of nanoparticles to instruct them to self-assemble into specific nanoscale structures, clusters, and three-dimensional organizations. Novel materials designedmore » and fabricated this way promise use in photovoltaics, energy storage, catalysis, cell-targeted systems for more effective medical treatments, and biomolecular sensing for environmental monitoring and medical applications. To find out more about the rapid evolution of this nanoassembly method and its applications, join Physicist Oleg Gang of the Center for Functional Nanomaterials (CFN) as he gives the 474th Brookhaven Lecture, titled “Self-Assembly by Instruction: Designing Nanoscale Systems Using DNA-Based Approaches." Gang, who has led this work at the CFN, will explain the rapid evolution of this nanoassembly method, and discuss its present and future applications in highly specific biosensors, optically active nano-materials, and new ways to fabricate complex architectures in a rational manner via self-assembly. Gang and his colleagues used the CFN and the National Synchrotron Light Source (NSLS) facilities to perform their groundbreaking research. At the CFN, the scientists used electron microscopes and optical methods to visualize the clusters that they fabricated. At the NSLS, they applied x-rays to study a particles-assembly process in solution, DNA’s natural environment. Gang earned a Ph.D. in soft matter physics from Bar-Ilan University in 2000, and he was a Rothschild Fellow at Harvard University from 1999 to 2002. After joining BNL as a Goldhaber Fellow in 2002, he became an assistant scientist at the CFN in 2004. He became the CFN’s leader for Soft and Biological Nanomaterials Theme Group in 2006, and earned the title of scientist in 2009.

    Conformity--defined here by the fact that an individual displays a particular behavior because it is the most frequent the individual witnessed in others--has long been recognized by social psychologists as one of the main categories of social influence. Surprisingly, it is only recently that conformity has become an active topic in animal and comparative biology. As in any new and rapidly growing field, however, definitions, hypotheses, and protocols are diverse, not easy to organize in a coherent way, and sometimes seriously in conflict with one another. Here we pursue greater coherence by reviewing the newer literature on conformity in behavioral ecology and evolutionary biology in light of the foundational work in social psychology. We suggest that the knowledge accumulated in social psychology can be exploited by behavioral ecologists and evolutionary biologists to bring conceptual clarity to the field, avoid some experimental pitfalls, and help design new and challenging experiments. In particular, we propose that the notions of informational and normative conformity that, until now, have been little recognized in recent literature can resolve some important controversies. In turn, research on animal culture should be of great interest to social scientists, because understanding human culture and human uniqueness requires an evolutionary analysis of our cognitive capacities and their evolutionary origins. Our review suggests excellent opportunities for social and natural scientists to join forces in building an interdisciplinary and integrative approach to the pervasive phenomenon of conformity.

    The Center for Vaccine Development - Mali (CVD - Mali), the World Health Organization's regional office in Africa (WHO/AFRO), and the CVD at the University of Maryland School of Medicine hosted the 10th African Rotavirus Symposium in Bamako, Mali on 1-2 June 2016. The symposium is coordinated by WHO/AFRO, the Regional Rotavirus Reference Laboratories, and the African Rotavirus Network (ARN), with support from the Bill & Melinda Gates Foundation. The event brings together leading rotavirus researchers, scientists, and policy-makers from across Africa and the world. Over 150 participants, from 31 countries, including 27 in Africa, joined forces to address the theme "Reaching Every Child in Africa with Rotavirus Vaccines." This symposium, the first in francophone Africa, occurred at an unprecedented time when 33 African countries had introduced rotavirus vaccines into their national immunization programs. The symposium concluded with a Call to Action to introduce rotavirus vaccines in the 21 remaining African countries, to increase access in countries with existing vaccination programs, and to continue surveillance and research on rotavirus and other diarrheal diseases.

    2017-11-01

    It is difficult to imagine today how dramatically global nuclear risks changed 25 years ago as the Soviet Union disintegrated. Instead of the threat of mutual nuclear annihilation, the world became concerned that Russia and the other 14 former Soviet states would lose control of their huge nuclear assets - tens of thousands of nuclear weapons, more than a million kilograms of fissile materials, hundreds of thousands of nuclear workers, and a huge nuclear complex. I will describe how scientists and engineers at the DOE laboratories, with a focus on Los Alamos, Lawrence Livermore and Sandia national laboratories, joined forces with those at the Russian nuclear weapon institutes for more than 20 years to avoid what looked like the perfect nuclear storm - a story told in the two-volume book Doomed to Cooperate1 published in 2016. Due to an internal processing error, an incorrect version of this article was published on 15 November 2017 that omitted the footnotes. AIP Publishing apologizes for this error.

    While there is not complete agreement on the microscopic mechanism of superconductivity in alkali-metal-doped C[sub 60], further research may well lead to the production of analogous materials that lose resistance at even higher temperatures. Carbon 60 is a fascinating and arrestingly beautiful molecule. With 12 pentagonal and 20 hexagonal faces symmetrically arrayed in a soccer-ball-like structure that belongs to the icosahedral point group, I[sub h], its high symmetry alone invites special attention. The publication in September 1990 of a simple technique for manufacturing and concentrating macroscopic amounts of this new form of carbon announced to the scientific community that enablingmore » technology had arrived. Macroscopic amounts of C[sub 60] (and the higher fullerenes, such as C[sub 70] and C[sub 84]) can now be made with an apparatus as simple as an arc furnace powered with an arc welding supply. Accordingly, chemists, physicists and materials scientists have joined forces in an explosion of effort to explore the properties of this unusual molecular building block. 23 refs., 6 figs.« less

    1988-01-01

    The results of the analysis conducted on the Joined Wing Configuration study are presented. The joined wing configuration employs a conventional fuselage and incorporates two wings joined together near their tips to form a diamond shape in both plan view and front view. The arrangement of the lifting surfaces uses the rear wing as a horizontal tail and as a forward wing strut. The rear wing has its root at the tip of the vertical stabilizer and is structurally attached to the trailing edge of the forward wing. This arrangement of the two wings forms a truss structure which is inherently resistant to the aerodynamic bending loads generated during flight. This allows for a considerable reduction in the weight of the lifting surfaces. With smaller internal wing structures needed, the Joined Wing may employ thinner wings which are more suitable for supersonic and hypersonic flight, having less induced drag than conventional cantilever winged aircraft. Inherent in the Joined Wing is the capability of the generation of direct lift and side force which enhance the performance parameters.

    Following the atomic bomb attacks on Japan in 1945, scientists from the United States and Japan joined together to study the Hibakusha - the bomb affected people in what was advertised as a bipartisan and cooperative effort. In reality, despite the best efforts of some very dedicated and earnest scientists, the early years of the collaboration were characterized by political friction, censorship, controversy, tension, hostility, and racism. The 70-year history, scientific output and cultural impact of the Atomic Bomb Casualty Commission and the Radiation Effects Research Foundation are described in the context of the development of Occupied Japan.

    2014-12-01

    Observations of the cuticle of the Boston Spiny Lobster using scanning electron microscope (SEM) show that it is a natural biocomposite consisting of chitin fibers and sclerotic-protein matrix with hierarchical and helicoidal structure. The SEM images also indicate that there is a hole-pin joining structure in the cuticle. In this joining structure, the chitin fibers in the neighborhood of the joining holes continuously round the holes to form a fiber-round-hole distribution. The maximum pullout force of the fibers in the fiber-round-hole distribution, which is closely related to the fracture toughness of the cuticle, is investigated and compared with that of the fibers in non-fiber-round-hole distribution based on their representative models. It is revealed that the maximum pullout force of the fibers in the fiber-round-hole distribution is significantly larger than that of the fibers in the non-fiber-round-hole distribution, and that a larger diameter of the hole results in a larger difference in the maximum pullout forces of the fibers between the two kinds of the fiber distributions. Inspired by the fiber-round-hole distribution found in the cuticle, composite specimens with the fiber-round-hole distribution were fabricated with a special mold and process to mirror the fiber-round-hole distribution. The fracture toughness of the biomimetic composite specimens is tested and compared with that of the conventional composite specimens with the non-fiber-round-hole distribution. It is demonstrated that the fracture toughness of the biomimetic composite specimens with the fiber-round-hole distribution is significantly larger than that of the conventional composite specimens with the non-fiber-round-hole distribution.

    Science outreach demystifies science, and outreach media gives scientists a voice to engage the public. Today scientists are expected to communicate effectively not only with peers but also with a braod public audience, yet training incentiives are sometimes scarce. Media creation training is even less emphasized. Editing video to modern standards takes practice; arrangling light and framing shots isn't intuitive. While great tutorials exist, learning videography, story boarding, editing and sharing techniques will always require a commitment of time and effort. Yet ideally sharing science should be low-hanging fruit. FrontierScientists, a science-sharing website funded by the NSF, seeks to let scientists display their breakthroughs and share their excitement for their work with the public by working closely yet non-exhaustively with a professional media team. A director and videographer join scientists to film first-person accounts in the field or lab. Pictures and footage with field site explanations give media creators raw material. Scientists communicate efficiently and retain editorial control over the project, but a small team of media creators craft the public aimed content. A series of engaging short videos with narrow focuses illuminate the science. Written articles support with explanations. Social media campaigns spread the word, link content, welcome comments and keep abreast of changing web requirements. All FrontierScientists featured projects are aggregated to one mobile-friendly site available online or via an App. There groupings of Arctic-focused science provide a wealth of topics and content to explore. Scientists describe why their science is important, what drew them to it, and why the average American should care. When scientists share their work it's wonderful; a team approach is a schedule-friendly way that lets them serve as science communicators without taking up a handful of extra careers.

Customarily a threaded joining bolt engages one of the components to be joined, and a threaded nut is placed on that bolt against the other component so they can be drawn together by a releasable locking assembly. The releasable locking assembly herein includes a plunger having one end coupled to one end of a plunger bolt. The other end is flanged to abut and compress a coil spring when the plunger is advanced toward the interface plane between the two components. When the plunger is so advanced toward the interface plane, the end of the plunger bolt can be connected to the joining bolt. Thus during retraction the joining bolt is drawn to one side of the interface plane by the force of the expanding spring.

    The scientific advances being made across all disciplines are creating ever-increasing opportunities to enhance our knowledge of biological systems and how they relate to human disease. One of the central driving forces in discovering new medicines is medicinal chemistry, where the design and synthesis of novel compounds has led to multiple drugs. Chemical biology, sitting at the interface of many disciplines, has now emerged as a major contributor to the understanding of biological systems and is becoming an integral part of drug discovery. Bringing chemistry and biology much closer and blurring the boundaries between disciplines is creating new opportunities to probe and understand biology; both disciplines play key roles and need to join forces and work together effectively to synergize their impact. The power of chemical biology will then reach its full potential and drive innovation, leading to the discovery of transformative medicines to treat patients. Advances in cancer biology and drug discovery highlight this potential. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2016-02-01

    Catalan surgeon Moisès Broggi entered medical practice in 1931 as Spain was modernizing rapidly. Five years later, however, an attempted military coup sparked a nationwide civil war. Broggi offered his services to the embattled Republic and joined the Medical Service of the International Brigades. He served alongside colleagues from many countries, helping to develop advances in military medicine and especially trauma surgery. Broggi chose to remain working in Barcelona as Franco's Nationalist forces entered the city, in spite of the risk of reprisal he faced as a former officer of the International Brigades. Although forced from his leading position in the public health service, he developed a distinguished private practice. In the year of Franco's death he became President of Barcelona's Royal Academy of Medicine and he received many other honours. Just months before his death at the remarkable age of 104, Dr Moisès Broggi continued to discuss and write about the concerns that had directed the course of his life--advances in medical science and the intellectual and political repression that had hindered delivery of those advances. In an article titled Exile and Silence he noted the groundbreaking work carried out under the auspices of the prestigious scientific institutions founded during Spain's Second Republic and the subsequent dark decades of exile suffered by many of their prominent scientists, some of them his close friends. © The Author(s) 2014.

  5. Calorie restriction, post-reproductive life span, and programmed aging: a plea for rigor.

    PubMed

    De Grey, Aubrey D N J

    2007-11-01

    All scientists are acutely aware of the profound challenge that they face when communicating scientific findings to nonscientists, especially when great uncertainty is involved and when the topic is of personal interest to the general public. Simplification of the issues--sometimes extending to a degree of oversimplification--is a sad but generally recognized necessity. It is not, however, a necessity when scientists communicate with each other, and when that happens, the explanation may lie elsewhere: either in the speaker's vested interests or in overconfidence on the speaker's part in the extent to which he or she has grasped the topic under discussion. Both these explanations are serious allegations and must not be made without good reason, not least because an alternative explanation is often the entirely legitimate preference for scientific "shorthand." However, when a general tendency toward oversimplification emerges within an expert community, not only in informal interactions but in learned publications, the field in question can suffer a loss of reputation for rigor, which may especially infect younger scientists joining that field (or contemplating joining it). I feel that this has occurred to a dangerous degree within biogerontology in respect of the way in which the effect of the environment on the rate of aging-whether that of an individual organism or of a lineage-is described. There are still important controversies in that area, but I refer here strictly to issues concerning which a thorough consensus exists. In this essay I highlight some fundamental tenets of biogerontology that are frequently, and to my mind problematically, mis-stated by many in this field in their printed pronouncements. Greater precision on these points will, I believe, benefit biogerontology at many levels, avoiding confusion among biogerontologists, among other biologists, and among the general public.

    At about this time every year, I renew my memberships to several scientific societies, and every year I ask myself the same question: “Should I bother?” In years past, the answer was easy because being a member came with tangible benefits, such as inexpensive journals and the ability to submit abstracts to annual meetings. Nowadays, these perks don’t seem very important. Most society journals are freely available online, and the proliferation of scientific meetings has made it easier to find venues to present my current research. Thus, the volume with which I ask that question—“should I bother?”—has steadily increased. Mostmore » scientific societies were established to promote the development and acceptance of a particular field of research. Society journals and annual meetings were the primary way this was accomplished. More recently, the larger societies have expanded their roles to include lobbying for increases in research funding and providing career advice. Although these are worthwhile activities, I don’t need to belong to multiple scientific societies to support them. I almost always renew my society memberships, but I think that it is more out of a sense of tradition than need. Clearly, I am not the only scientist who is ambivalent about societies. Judging from their newsletters, many of the larger societies are struggling with stagnant or declining memberships, especially among young scientists. Although it is the youngest scientists who potentially have the most to gain from a scientific society (from networking, career advice), they are the ones who usually are most poorly served by those societies. This is because scientific societies generally cater to the status quo, not to the new and emerging elements of a field.« less

  12. Who joins the network? Physicians' resistance to take budgetary co-responsibility.

    Managed Care (MC) is expected to provide health care at a lower cost than conventional provision. Therefore, Switzerland intends to promote MC by forcing health insurers to write MC contracts and introducing budgetary co-responsibility for ambulatory care physicians. A discrete choice experiment conducted in 2011 including 872 physicians reveals a strong preference heterogeneity with respect to network participation and alternative remuneration schemes. The number of physicians working in networks is unlikely to rise on a voluntary basis, while general practitioners are more likely to join networks than specialists with surgical activities. For physicians considering joining networks, cost savings are predicted to be higher than the estimated willingness-to-accept payments. Copyright © 2014 Elsevier B.V. All rights reserved.

    The Aerospace Corporation is a nonprofit company whose purposes are exclusively scientific: to provide research, development, and advisory services for space programs that serve the national interest, primarily the Air Force's Space and Missile Systems Center and the National Reconnaissance Office. The corporation's laboratory has a staff of about 150 scientists who conduct research in fields ranging from Space Sciences to Material Sciences and from Analytical Chemistry to Atomic Physics. As a consequence, Aerospace stands midway between an industrial research laboratory, focused on product development, and academic/national laboratories focused on basic science. Drawing from Dr. Camparo's personal experiences, the presentation will discuss advantages and disadvantages of a career at Aerospace, including the role of publishing in peer-reviewed journals and the impact of work on family life. Additionally, the presentation will consider the balance between basic physics, applied physics, and engineering in the work at Aerospace. Since joining Aerospace in 1981, Dr. Camparo has worked as an atomic physicist specializing in the area of atomic clocks, and has had the opportunity to experiment and publish on a broad range of research topics including: the stochastic-field/atom interaction, radiation effects on semiconductor materials, and stellar scintillation.

    A brief review of Dr. Hilda Cid, Chilean scientist who excelled in the field of crystallography, is presented. Dr. Cid was born in 1933 in Talcahuano, where she completed her primary and secondary education, graduating as a Teacher of mathematics and physics from the University of Chile in 1958. She continued graduate studies at MIT, USA, where obtained the PhD in 1964. Upon her return to Chile, she joined the Austral University in Valdivia, where she dedicated to characterize, by X-ray, biological material. During that time, she was actively involved in the social changes taking place in the university and in the country. Thus, following the bloody coup of 1973, she and her family were persecuted and forced to go into exile to Sweden. In the decade of the 1980 she returns to Chile, and settles at University of Concepción, where she teaches, conducts research and organizes a number of latino-american courses and symposiums. Knowing that Hilda Cid formed a real school, where her students -now distinguished professionals and researchers- cast their teachings through Chile and other countries, we ended the article with a reflection about why Hilda Cid, despite its obvious scientific achievements, remains ignored by most of the scientific establishment in Chile.

  18. Forensic Metrology: Its Importance and Evolution in the United States

    Forensic measurements play a significant role in the U.S. criminal justice system. Guilt or innocence, or the severity of a sentence, may depend upon the results of such measurements. Until recently, however, forensic disciplines were largely unaware of the field of metrology. Accordingly, proper measurement practices were often, and widely, neglected. These include failure to adopt proper calibration techniques, establish the traceability of results and determine measurement uncertainty. These failures undermine confidence in verdicts based upon forensic measurements. Over the past decade, though, the forensic sciences have been introduced to metrology and its principles leading to more reliable measurement practices. The impetus for this change was driven by many forces. Pressure came initially from criminal defense lawyers challenging metrologically unsound practices and results relied upon by government prosecutions. Litigation in the State of Washington led this movement spurring action by attorneys in other jurisdictions and eventually reform in the measurement practices of forensic labs around the country. Since then, the greater scientific community, other forensic scientists and even prosecutors have joined the fight. This paper describes the fight to improve the quality of justice by the application of metrological principles and the evolution of the field of forensic metrology.

    2016-05-24

    In the present work, a recently developed solid state joining technique, Friction self-piercing riveting (F-SPR), has been applied for joining high strength aluminum alloy AA7075-T6 to magnesium alloy AZ31B. The process was performed on a specially designed machine where the spindle can achieve the motion of sudden stop. Effects of rivet rotating rate and punch speed on axial plunge force, torque, joint microstructure and quality have been analyzed systematically. During F-SPR, higher rotating rate and slower punch speed can reduce axial force and torque, which correspondingly results in a slightly smaller interlock between rivet leg and joined materials. Improved localmore » flowability of both aluminum and magnesium alloys under a higher rotating speed results in a thicker aluminum layer surrounding the rivet leg, where formation of Al-Mg intermetallics was observed. Equivalent joint strength obtained in this study are higher than the yield strength of the AZ31 Mg alloy. One of the tensile failure modes is the rivet fracture, which is due to local softening of rivet leg from frictional heat. Lastly, other two failure modes include rivet pullout and shear through of bottom sheet.« less

    This commentary seeks to define the areas of social pharmacy and clinical pharmacy to uncover what they have in common and what still sets them apart. Common threats and challenges of the two areas are reviewed in order to understand the forces in play. Forces that still keep clinical and social pharmacy apart are university structures, research traditions, and the management of pharmacy services. There are key (but shrinking) differences between clinical and social pharmacy which entail the levels of study within pharmaceutical sciences, the location in which the research is carried out, the choice of research designs and methods, and the theoretical foundations. Common strengths and opportunities are important to know in order to join forces. Finding common ground can be developed in two areas: participating together in multi-disciplinary research, and uniting in a dialogue with internal and external key players in putting forth what is needed for the profession of pharmacy. At the end the question is posed, “What’s in a name?” and we argue that it is important to emphasize what unifies the families of clinical pharmacy and social pharmacy for the benefit of both fields, pharmacy in general, and society at large.

    Research in critical care extends from the bench to the bedside, involving multiple departments, specialties, and funding organizations. Because of this diversity, it has been difficult for all stakeholders to collectively identify challenges and establish priorities. To define a comprehensive agenda for critical care research using input from a broad range of stakeholders to serve as a blueprint for future initiatives. The Critical Care Societies Collaborative (CCSC), consisting of the leadership of the American Association of Critical-Care Nurses (AACN), the American College of Chest Physicians (ACCP), the American Thoracic Society (ATS), and the Society of Critical Care Medicine (SCCM), joined the US Critical Illness and Injury Trials Group (USCIITG) in forming a task force to define a comprehensive critical care research agenda. This group of 25 identified experts was divided into subgroups to address basic, translational, clinical, implementation, and educational research. The subgroups met via conference calls, and the entire task force met in person for a 2-day session. The result was a detailed discussion of the research priorities that served as the basis for this report. The task force identified challenges, specific priority areas, and recommendations for process improvements to support critical care research. Additionally, four overarching themes emerged: 1) the traditional "silo-ed" approach to critical care research is counterproductive and should be modified; 2) an approach that more effectively links areas of research (i.e., basic and translational research, or clinical research and implementation) should be embraced; 3) future approaches to human research should account for disease complexity and patient heterogeneity; and 4) an enhanced infrastructure for critical care research is essential for future success. This document contains the themes/recommendations developed by a large, multiprofessional cross section of critical care scientists, clinicians, and educators.

  9. Serial elastic elements in the damselfly wing: mobile vein joints contain resilin

    Two main types of joints occur in the damselfly wing: mobile and immobile. Some longitudinal veins (RP2(-), RP3&4(-), and MP(-)) are elastically joined with cross veins, whereas other longitudinal veins (IR1(+), IR2(+), MA(+), CuA'(+)) are firmly joined with cross veins. In this study we mapped the distribution of serial elastic elements in the wing. The occurrence of resilin, a rubberlike protein, in mobile joints suggests that the automatic twisting mechanism of the leading edge by aerodynamic force works not by flexibility but by the elasticity of these joints. First, it should result in elastic energy storage in the distal areas of the wing. Second, serial elastic elements of wing presumably act as dampers of an aerodynamic force, which are responsible for gradual twisting of the leading edge.

  11. Leveraging, Synergies and Cloning: Thoughts on How Scientists can Multiply their Impact on Education and Public Outreach

    NASA Astrophysics Data System (ADS)

    Chambers, L. H.

    2011-12-01

    An individual scientist might look at the huge numbers of students and the public who constitute a potential audience for education and public outreach (EPO) and conclude that he/she has no hope to make a difference. This talk will share some strategies that have the potential to multiply a scientist's for maximum effect, and some evidence that indeed one person CAN make a difference. The first strategy is to leverage: that is, find a person or group who already has an ongoing EPO activity that relates to your subject area, and use it as a way to get your information out to an existing, interested audience. This benefits you because you don't have to begin from scratch to build an audience for your information, and it benefits them because they get great new content to keep their audience interested. The second strategy is to synergize: that is, cooperate or coordinate with an existing EPO group, or with colleagues with similar interests. Use your expertise to develop new resources that fit into an existing program. Cooperate with an existing EPO group so they can help you navigate details like review processes, aligning your resource to education standards, and helping tailor your information to the needs of the education audience. The third strategy is to use technology to approximate cloning: that is, to propagate yourself and your information via multiple channels. However, this strategy should not be used until after you have tested and honed your information through a number of in-person interactions with the audience(s) you seek to reach, and have developed some communications skills that help you connect with students and teachers. One lesson that you may learn from such interactions is that scientists aren't like other people. We have a distinct vocabulary, culture, and habits of mind that distinguish us from others. This is a key strength for science, but sometimes a barrier for EPO. By personal contact with non-scientists, we can learn again how to communicate outside of science. There is one major difference between the communication scientists normally do, at conferences such as AGU, and that which they do for EPO: novelty vs. repetition. While scientists seek to present the latest discovery to each other, 4th graders need to learn basically the same thing every year. Thus, the information you share with students does not need to be totally cutting edge; it should ideally draw connections between the fundamentals they are learning and exciting areas of recent scientific inquiry. Once you have figured out a message and style that works with live audiences, it is time to explore how emerging technologies can multiply your impact beyond that achieved by individual in-person interactions. Technology is advancing rapidly, and new and better options are continually becoming available: webinars, video, QR codes, the list goes on! Again, collaboration and cooperation are key strategies here: join forces with technical experts, EPO groups who use these new tools, and other interested individuals with key knowledge. The bottom line of scientists doing EPO: It's worth it! Studies show that a very small fraction of people in the US actually know a scientist. It is important for scientists to get out there and demonstrate that, in fact, scientists are real people!

    Many fisheries professionals may not be in the job they originally envisioned for themselves when they began their undergraduate studies. Rather, their current positions could be the result of unexpected, opportunistic, or perhaps even “lucky” open doors that led them down an unexpected path. In many cases, a mentor helped facilitate the unforeseen trajectory. We offer three unique stories about joining a federal fisheries research laboratory, from the perspective of a scientist, a joint manager-scientist, and a manager. We also use our various experiences to form recommendations that should help the next generation of fisheries professionals succeed in any stop along their journey, including being open to opportunities, setting high expectations, and finding a strong and supportive team environment to work in.

    1972-01-01

    At the current state-of-technology there are many joining processes that can be used to make sound welds in TD-NiCr sheet. Some of these that are described in this report are electron beam welding (EBW), gas-tungsten arc welding (GTAW), diffusion welding (DFW), resistance spot welding (RSW), resistance seam welding (RSEW), and brazing. Roll welding (RW) and explosion welding (EXW) have not been developed to the point where they can be used to make sound welds in TD-NiCr. Joining work that has previously been done on TD-NiCr by various organizations, both privately supported and under Air Force and NASA contracts, is described in this summary. Current work is also described that is being done at General Dynamics/Convair (under NASA contract) and at NASA/Lewis to develop and evaluate DFW, RSW, RSEW, and brazing. Preliminary comparisons of joining processes are made for typical applications. A brief description of the manufacture of TD-NiCr sheet by a recently standardized process (under NASA contract) also is given.

    Miki Takasuna describes knowledge transfer between elite communities of scientists, a process by which ideas become structurally transformed in the host culture. By contrast, a process that we have termed knowledge transfer by deelitization occurs when (a) participatory action researchers work with a community to identify a problem involving oppression or exploitation. Then (b) community members suggest solutions and acquire the tools of analysis and action to pursue social actions. (c) Disadvantaged persons thereby become more aware of their own abilities and resources, and persons with special expertise become more effective. (d) Rather than detachment and value neutrality, this joint process involves advocacy and structural transformation. In the examples of participatory action research documented here, Third World social scientists collaborated with indigenous populations to solve problems of literacy, community-building, land ownership, and political voice. Western social scientists, inspired by these non-Western scientists, then joined in promoting PAR both in the Third World and in Europe and the Americas, e.g., adapting it for solving problems of people with disabilities or disenfranchised women. Emancipatory goals such as these may even help North American psychologists to break free of some methodological chains and to bring about social and political change.

    During those early halcyon days of the study of radioactivity, one young Canadian woman, Harriet Brooks, joined Ernest Rutherford's group as his first research student. Later, she joined J.J. Thomson's group in Cambridge and, finally, Marie Curie's group in Paris. During her short research career, she made several important contributions to science. She investigated the nature of 'emanation' from radium; discovered that radioactive substances could undergo successive decay; and first reported the recoil of the radioactive atom. Much of this research was published under her name alone though Rutherford made extensive reference to her discoveries in his Bakerian lecture of 1904. Brooks life is of interest not only in what she accomplished, but also in the challenges she faced as a pioneering woman scientist in the early part of the twentieth century. In the presentation we will blend the account of her life and work with the societal context. This work was accomplished jointly with Marelene F. Rayner-Canham.

  7. HUBBLE AND KECK DISCOVER GALAXY BUILDING BLOCK

    NASA Technical Reports Server (NTRS)

    2002-01-01

    This NASA Hubble Space Telescope image shows a very small, faint galaxy 'building block' newly discovered by a unique collaboration between ground- and space-based telescopes. Hubble and the 10-meter Keck Telescopes in Hawaii joined forces, using a galaxy cluster which acts as gravitational lens to detect what scientists believe is one of the smallest very distant objects ever found. The galaxy cluster Abell 2218 was used by a team of European and American astronomers led by Richard Ellis (Caltech) in their systematic search for intrinsically faint distant star-forming systems. Without help from Abell 2218's exceptional magnifying power to make objects appear about 30 times brighter, the galaxy building block would have been undetectable. In the image to the right, the object is seen distorted into two nearly identical, very red 'images' by the gravitational lens. The image pair represents the magnified result of a single background object gravitationally lensed by Abell 2218 and viewed at a distance of 13.4 billion light-years. The intriguing object contains only one million stars, far fewer than a mature galaxy, and scientists believe it is very young. Such young star-forming systems of low mass at early cosmic times are likely to be the objects from which present-day galaxies have formed. In the image to the left, the full overview of the galaxy cluster Abell 2218 is seen. This image was taken by Hubble in 1999 at the completion of Hubble Servicing Mission 3A.

  8. Industrial shifts, female employment, and occupational differentiation: a dynamic model for American cities, 1960-1970.

    PubMed

    Semyonov, M; Scott, R I

    1983-05-01

    Sex-linked occupational differentiation has been seen as influenced by both the industrial structure of the economy and the sex composition of the labor force. Here, with a sample of 70 SMSAs, it was found (a) that the odds of men relative to women of joining professional and managerial occupations increased between 1960 and 1970, and (b) that this increase was dependent on the growth of tertiary industries and the greater number of women joining the cash economy. The observed effect of industrial shifts on sex-occupational differentiation, however, is argued to be a spurious consequence of the gender-composition of the work force. Specifically, the development of tertiary industries generates greater demand for female labor. Intensive recruitment of women to the labor force in turn increases occupational differentiation because females, in sex-typed labor markets, are likely to be channeled in disproportionate numbers away from upper-status occupations. The findings demonstrate that traditional modernization theory is unable to account for this. However, the results lend support to expectations derived from a labor market sex-segmentation approach.

    NASA Astrophysics Data System (ADS)

    Roth, Gian-Luca; Rung, Stefan; Hellmann, Ralf

    2017-06-01

    We report on the joining of transparent thermoplastic polymers using infrared femtosecond laser pulses. Due to nonlinear absorption, the developed micro-welding process for cyclo-olefin copolymers does not require any intermediate absorbing layers or any surface pre-processing of the welding partners. In view of an optimized and stable micro-welding process, the influence of the welding speed and focal position on both, the quality and shear force strength are investigated. We highlight that welding seam widths of down to 65 μm are feasible for welding speeds of up to 75 mm/s. However, a variation of the welding speed affects the required focal position for a successful joining process. The shear force strength of the welding seam is determined to 37 MPa, which corresponds to 64% of the shear strength of the bulk material and is not affected by the welding speed.

  15. Ultrasonic Low-Friction Containment Plate for Thermal and Ultrasonic Stir Weld Processes

    NASA Technical Reports Server (NTRS)

    Graff, Karl; Short, Matt

    2013-01-01

    The thermal stir welding (TSW) process is finding applications in fabrication of space vehicles. In this process, workpieces to be joined by TSW are drawn, by heavy forces, between "containment plates," past the TSW tool that then causes joining of the separate plates. It is believed that the TSW process would be significantly improved by reducing the draw force, and that this could be achieved by reducing the friction forces between the workpieces and containment plates. Based on use of high-power ultrasonics in metal forming processes, where friction reduction in drawing dies has been achieved, it is believed that ultrasonic vibrations of the containment plates could achieve similar friction reduction in the TSW process. By applying ultrasonic vibrations to the containment plates in a longitudinal vibration mode, as well as by mounting and holding the containment plates in a specific manner such as to permit the plates to acoustically float, friction between the metal parts and the containment plates is greatly reduced, and so is the drawing force. The concept was to bring in the ultrasonics from the sides of the plates, permitting the ultrasonic hardware to be placed to the side, away from the equipment that contains the thermal stir tooling and that applies clamping forces to the plates. Tests demonstrated that one of the major objectives of applying ultrasonics to the thermal stir system, that of reducing draw force friction, should be achievable on a scaled-up system.

    Active engagement of scientists in education and public outreach (E/PO) activities is beneficial for scientists, classrooms, and the general public. Scientist visibility in the public arena is important to garner public support, whose tax dollars fund scientific programs. Scientists are important disseminators of current, accurate scientific knowledge. They also, perhaps more importantly, understand the nature and process of science and have the means of understanding and addressing many of the issues facing society. Research has shown that while the public is interested in science, not all members are necessarily scientifically literate; additionally there is evidence than many students are not prepared for, or choosing to participate in science careers. And yet, a scientifically engaged, literate, and supportive public is a necessary partner in addressing important global challenges of the future. E/PO is a wonderful opportunity for scientists to demonstrate that science is interesting, exciting, fun, challenging, and relevant to society. In doing so, they can transfer ownership of science to the public through a variety of vehicles by increasing access to scientific thought and discovery. Through partnerships with E/PO professionals, teachers, or journalists, scientists can improve their communication and teaching skills, whether in an E/PO setting or their higher education careers. Sharing with the public what scientists do is an effective way to engage people in the scientific process and to express scientists' enthusiasm for what they do. Scientist involvement in E/PO also shows the public that scientists are real people and provides important role models for the next generation of scientists. There are many opportunities to get involved in E/PO!

    2014-04-01

    As the body of scientific knowledge in a discipline increases, there is pressure for specialization. Fields spawn subfields that then become entities in themselves that promote further specialization. The process by which scientists join specialized groups has remarkable similarities to the guild system of the middle ages. The advantages of specialization of science include efficiency, the establishment of normative standards, and the potential for greater rigor in experimental research. However, specialization also carries risks of monopoly, monotony, and isolation. The current tendency to judge scientific work by the impact factor of the journal in which it is published may have roots in overspecialization, as scientists are less able to critically evaluate work outside their field than before. Scientists in particular define themselves through group identity and adopt practices that conform to the expectations and dynamics of such groups. As part of our continuing analysis of issues confronting contemporary science, we analyze the emergence and consequences of specialization in science, with a particular emphasis on microbiology, a field highly vulnerable to balkanization along microbial phylogenetic boundaries, and suggest that specialization carries significant costs. We propose measures to mitigate the detrimental effects of scientific specialism.

    CosmoQuest is an online citizen science and astronomy education portal that invites users to explore the universe. Since its launch in January 2012, several thousand citizen scientists have participated in mapping and discovery projects involving the Moon, the Kuiper Belt, and asteroid Vesta. Since our goal is to support community building as well as involving users with citizen science tasks, we are interested in what motivates users to join the site, participate in the science, participate in the forums, and come back to the site over a period of time. We would also like to efficiently target our social media interactions towards activities that are more likely to bring new and existing users to the site. With those goals in mind, we analyze site usage statistics and correlate them with specific, targeted social media campaigns to highlight events or projects that CosmoQuest has hosted in its first year. We also survey our users to get a more detailed look at citizen scientist motivations and the efficacy of our community building activities.

  12. Desired machines: cinema and the world in its own image.

    PubMed

    Canales, Jimena

    2011-09-01

    In 1895 when the Lumière brothers unveiled their cinematographic camera, many scientists were elated. Scientists hoped that the machine would fulfill a desire that had driven research for nearly half a century: that of capturing the world in its own image. But their elation was surprisingly short-lived, and many researchers quickly distanced themselves from the new medium. The cinematographic camera was soon split into two machines, one for recording and one for projecting, enabling it to further escape from the laboratory. The philosopher Henri Bergson joined scientists, such as Etienne-Jules Marey, who found problems with the new cinematographic order. Those who had worked to make the dream come true found that their efforts had been subverted. This essay focuses on the desire to build a cinematographic camera, with the purpose of elucidating how dreams and reality mix in the development of science and technology. It is about desired machines and their often unexpected results. The interplay between what "is" (the technical), what "ought" (the ethical), and what "could" be (the fantastical) drives scientific research.

  14. Scientists and K-12: Experience from The Science House

    NASA Astrophysics Data System (ADS)

    Haase, David G.

    2003-03-01

    In working with K-12 science and mathematics education, scientists may take on many different roles - from presenter to full-time partner. These roles are illustrated in the activities of The Science House, a K-12 education program of North Carolina State University, (www.science-house.org) which partners with teachers and students across the state to promote inquiry-based learning in mathematics and science. While it is important to involve scientists in K-12, most universities do not have effective means to make the connections. In our efforts to do so, which began with a few teacher workshops and now encompasses six offices across NC, we have sought to join the interests of the university (research, teaching, student recruiting) to the needs of K-12.

  15. Out of the SHADOW: watch parts in the spotlight -- laser beam microwelding of delicate watch components

    NASA Astrophysics Data System (ADS)

    Kramer, Thorsten; Olowinsky, Alexander M.

    2003-07-01

    Conventional joining techniques like press fitting or crimping require the application of mechanical forces to the parts which, in combination with the tolerances of both parts to be joined, lead to imprecision and poor tensile strength. In contrast, laser beam micro welding provides consistent joining and high flexibility and it acts as an alternative as long as press fitting, crimping, screwing or gluing are not capable of batch production. Different parts and even different metals can be joined in a non-contact process at feed rates of up to 60 m/min and with weld seam lengths from 0.6 mm to 15.7 mm. Due to the low energy input, typically 1 J to 6 J, a weld width as small as 50 μm and a weld depth as small as 20 μm have been attained. This results in low distortion of the joined watch components. Since the first applications of laser beam micro welding of watch components showed promising results, the process has further been enhanced using the SHADOW technique. Aspects of the technique such as tensile strength, geometry and precision of the weld seam as well as the acceptance amongst the -mostly conservative- watch manufacturers have been improved.

  18. High-Powered, Ultrasonically Assisted Thermal Stir Welding

    NASA Technical Reports Server (NTRS)

    Ding, Robert

    2013-01-01

    This method is a solid-state weld process capable of joining metallic alloys without melting. The weld workpieces to be joined by thermal stir welding (TSW) are drawn, by heavy forces, between containment plates past the TSW stir tool that then causes joining of the weld workpiece. TSW is similar to friction stir welding (FSW) in that material is heated into a plastic state (not melted) and stirred using a stir rod. The FSW pin tool is an integrated geometrical structure consisting of a large-diameter shoulder, and a smaller-diameter stir pin protruding from the shoulder. When the pin is plunged into a weld workpiece, the shoulder spins on the surface of the weld workpiece, thus inducing frictional heat into the part. The pin stirs the fraying surfaces of the weld joint, thus joining the weld workpiece into one structure. The shoulder and stir pin of the FSW pin tool must rotate together at a desired rotational speed. The induced frictional energy control and stir pin control of the pin tool cannot be de-coupled. The two work as one integrated unit. TSW, on the other hand, de-couples the heating and stirring of FSW, and allows for independent control of each process element. A uniquely designed induction coil heats the weld workpiece to a desired temperature, and once heated, the part moves into a stir rod whose RPM is also independently controlled. As the weld workpiece moves into the stir rod, the piece is positioned, or sandwiched, between upper and lower containment plates. The plate squeezes together, thus compressing the upper and lower surfaces of the weld workpiece. This compressive force, also called consolidation force, consolidates the plastic material within the weld nugget material as it is being stirred by the stir rod. The stir rod is positioned through the center of the top containment plate and protrudes midway through the opposite lower containment plate where it is mechanically captured. The upper and lower containment plates are separated by a distance equal to the thickness of the material being welded. The TSW process can be significantly improved by reducing the draw forces. This can be achieved by reducing the friction forces between the weld workpieces and the containment plates. High-power ultrasonic (HPU) vibrations of the containment plates achieve friction reduction in the TSW process. Furthermore, integration of the HPU energy into the TSW stir rod can increase tool life of the stir rod, and can reduce shear forces to which the stir rod is subjected during the welding process. TSW has been used to successfully join 0.500-in (˜13-mm) thick commercially pure (CP) titanium, titanium 6AL- 4V, and titanium 6AL-4V ELI in weld joint lengths up to 9 ft (˜2.75-m) long. In addition, the TSW process was used to fabricate a sub-scale hexagonally shaped gun turret component for the U.S. Navy. The turret is comprised of six 0.5000-in (˜13-mm) thick angled welds. Each angled weld joint was prepared by machining the mating surfaces to 120deg. The angled weld joint was then fixtured using an upper and lower containment plate of the same geometry of the angled weld joint. The weld joint was then stirred by the stir rod as it and the upper and lower containment plates traverse through the angled joint prep.

  1. Art, science and social science in nursing: occupational origins and disciplinary identity.

    PubMed

    Rafferty, A M

    1995-09-01

    This paper forms part of a wider study examining the history and sociology of nursing education in England between 1860 and 1948. It argues that the question of whether nursing was an art, science and/or social science has been at the 'heart' of a wider debate on the occupational status and disciplinary identity of nursing. The view that nursing was essentially an art and a 'calling', was championed by Florence Nightingale. Ethel Bedford Fenwick and her allies insisted that nursing, like other professions, was a 'scientific' and technical enterprise. Social scientists later came to challenge nursing's claim to professionalism by analysing nursing work first within the context of industrial psychology. But they also advocated a rapprochement between nursing, health services and social science research, a challenge which we are in nursing, still striving to meet. This paper argues for a strong coalition of nursing with its former nineteenth century ally, social science, in the continuing struggle for change within nursing and health care policy. Rather than searching for some rarified and purified essence of nursing knowledge, it argues that nurses need to join forces with sociologists and economists in striving to shape the agenda for health services research and provide the evidential basis for health policy transformation more generally.

    2017-12-01

    Since 2016, select groups of students (aged 14-17) from the Independent School Foundation Academy (ISF), Hong Kong, have been constructing a Historical GIS system for the Needham Research Institute (NRI), Cambridge, UK, during their annual summer school in Cambridge. Students read the diaries and reports of Joseph Needham, the Cambridge scientist who worked in China from 1943 to 1946 as the head of the Sino-British Science Cooperation Office, and mapped out both Needham's itineraries and the location of Chinese scientific institutions he visited. By taking part in this project, students learnt two sets of skills: the historian's skills of reading and analyzing primary sources, and the geographer's skills of creating datasets and maps with a GIS software. This project will be carried on in future years, to gradually include other trips Joseph Needham undertook in China in the second half of the 20th century, thus making an essential contribution to the digitalization and the diffusion of the NRI's archives. As a historical researcher in NRI and an educator, the presenter will offer some reflections on the benefit of historical GIS projects as a venue par excellence for research institutions and schools to join force, enhancing both academic research and teaching with an enlarged social impact.

  3. Western Coordinating Committee-204 goals and why they are important to the future of animal production systems.

    PubMed

    Cherney, D J R

    2004-03-01

    There are scientists who believe that science is value-free and that social and ethical issues are not their concern. The birth of Dolly, the cloned lamb, greatly increased public and scientific awareness of ethical issues raised by molecular biology as they intersect with human experience. There are many other issues involving animal production systems, including animal welfare, rural community issues, and environmental concerns. Last year Germany became the first European nation to grant animals a constitutional right. Several European nations ban the use of traditional battery cages for laying hens and gestation crates for sows. In the US, 37 states have recently passed animal anticruelty laws. Times are changing, and if animal production systems are to be part of the future, animal scientists must join with society to solve these ethical issues. The Western Coordinating Committee-204 (WCC-204), Animal Bioethics, has as its goals to 1) create a forum in which animal scientists and nonanimal scientists may work together to examine and discuss contentious social issues, 2) provide a means of encouraging the development of research projects dealing with bioethics of the animal sciences, 3) develop mechanisms of outreach that would allow animal scientists to respond directly to consumers and critics, and 4) provide the means for ongoing critical analysis of the animal science professions in the context of their ability to address moral and sociopolitical issues. Animal scientists can no longer ignore social ethics, and by realizing the goals of Western Coordinating Committee-204, we can help maintain the future of animal production systems.

  4. Austria Declares Intent To Join ESO

    NASA Astrophysics Data System (ADS)

    2008-04-01

    At a press conference today at the University of Vienna's Observatory, the Austrian Science Minister Johannes Hahn announced the decision by the Austrian Government to seek membership of ESO from 1 July this year. ESO PR Photo 11/08 ESO PR Photo 11/08 Announcing Austria's Intent to Join ESO Said Minister Hahn: "With membership of ESO, Austria's scientists will receive direct access to the world's leading infrastructure in astronomy. This strengthens Austria as a place for research and provides an opportunity for young researchers to continue their work from here. With this move, Austria takes an important step in the reinforcement of Europe's science and research infrastructure." The decision constitutes a major breakthrough for Austrian scientists who have argued for membership of ESO for many years. Seeking membership in ESO also marks a step towards the further development of the European Research and Innovation Area, an important element of Europe's so-called Lisbon Strategy. "ESO welcomes the Austrian bid to join our organisation. I salute the Austrian Government for taking this important step and look forward to working closely with our Austrian friends and colleagues in the years to come," commented the ESO Director General, Tim de Zeeuw. For Austrian astronomers, ESO membership means not only unrestricted access to ESO's world-leading observational facilities including the world's most advanced optical telescope, the Very Large Telescope, and full participation in the quasi-global ALMA project, but also the possibility to participate on a par with their European colleagues in the future projects of ESO, including the realisation of ESO's Extremely Large Telescope project (E-ELT), which is currently in the design phase. All these projects require some of the most advanced technologies in key areas such as optics, detectors, lightweight structures, etc. Austrian participation in ESO opens the door for Austrian industry and major research institutes of the country to take part in the development of such technologies with their associated potential for industrial spin off. The main centres for astronomical research in Austria are at the Universities of Graz, Innsbruck and Vienna. Furthermore scientists in the area of mathematics, applied physics and computer sciences already expressed their interest to contribute to the development of advanced technologies required by ESO's future projects. The Austrian bid for ESO membership will be formally considered by the ESO Council at its next meeting on 3-4 June and is subject also to subsequent ratification by the Austrian Parliament.

    1998-03-18

    James Barrilleaux is the assistant chief pilot for ER-2s in the Flight Crew Branch of NASA's Dryden Flight Research Center, Edwards, California. The ER-2s--civilian variants of the military U-2S reconnaissance aircraft--are part of NASA's Airborne Science program. The ER-2s can carry airborne scientific payloads of up to 2,600 pounds to altitudes of about 70,000 feet to investigate such matters as earth resources, celestial phenomena, atmospheric chemistry and dynamics, and oceanic processes. Barrilleaux has held his current position since February 1998. Barrilleaux joined NASA in 1986 as a U-2/ER-2 pilot with NASA's Airborne Science program at Ames Research Center, Moffett Field, California. He flew both the U-2C (until 1989) and the ER-2 on a wide variety of missions both domestic and international. Barrilleaux flew high-altitude operations over Antarctica in which scientific instruments aboard the ER-2 defined the cause of ozone depletion over the continent, known as the ozone hole. He has also flown the ER-2 over the North Pole. Barrilleaux served for 20 years in the U.S. Air Force before he joined NASA. He completed pilot training at Reese Air Force Base, Lubbock, Texas, in 1966. He flew 120 combat missions as a F-4 fighter pilot over Laos and North Vietnam in 1970 and 1971. He joined the U-2 program in 1974, becoming the commander of an overseas U-2 operation in 1982. In 1983, he became commander of the squadron responsible for training all U-2 pilots and SR-71 crews located at Beale Air Force Base, Marysville, California. He retired from the Air Force as a lieutenant colonel in 1986. On active duty, he flew the U-2, F-4 Phantom, the T-38, T-37, and the T-33. His decorations included two Distinguished Flying Crosses, 12 Air Medals, two Meritorious Service Medals, and other Air Force and South Vietnamese awards. Barrilleaux earned a bachelor of science degree in chemical engineering from Texas A&M University, College Station, in 1964 and a master of science

    Joining by upset bulging is a mechanical joining method where axial load is applied to a tube to form two revolving bulges, which clamp the parts to be joined and create a force and form fit. It can be used to join tubes with other structures such as sheets, plates, tubes or profiles of the same or different materials. Other processes such as welding are often limited in joining multi-material assemblies or high-strength materials. With joining by upset bulging at room temperature, the main drawback is the possible initiation of damage (cracks) in the inner buckling zone because of high local stresses and strains. In this paper, a method to avoid the formation of cracks is introduced. Before forming the bulge the tube is locally heated by an induction coil. For the construction steel (E235+N) a maximum temperature of 700 °C was used to avoid phase transformation. For the numerical study of the process the mechanical properties of the tube material were examined at different temperatures and strain rates to determine its flow curves. A parametrical FE model was developed to simulate the bulging process with local heating. Experiments with local heating were executed and metallographic studies of the bulging area were conducted. While specimens heated to 500 °C showed small cracks left, damage-free flanges could be created at 600 and 700 °C. Static testing of damage-free bulges showed improvements in tensile strength and torsion strength compared to bulges formed at room-temperature, while bending and compression behavior remained nearly unchanged. In cyclic testing the locally heated specimens underwent about 3.7 times as many cycles before failure as the specimens formed at room temperature.

    2014-06-01

    Although oceanographers such as Roger Revelle are typically associated with key indicators of anthropogenic change, he and other scientists at midcentury had very different scientific priorities and ways of seeing the oceans. How can we join the narrative of the triumph of mathematical, dynamic oceanography with the environmental narrative? Dynamic methods entailed a broad set of values that touched the professional lives of marine scientists in a variety of disciplines all over the world, for better or for worse. The present essay highlights three aspects of "Bergen values" in need of greater exploration by scholars. First, how did the dominance of Scandinavian outlooks influence scientific questions across the broad spectrum of oceanography? Second, did oceanographers' particular means of making the oceans legible through instrumentation challenge their ability to perceive the oceans differently? Third, given the immense quantity of data, was the historical legacy of the dynamic oceanographers more descriptive than they imagined?

    Winter research and monitoring of icebound rivers, lakes, and coastal seas to date has usually involved seagoing civilian scientists leading survey efforts. However, because of poor weather conditions and a lack of safe research platforms, scientists collecting data during winter face some difficult and often insurmountable problems. To solve these problems and to further research and environmental monitoring goals, new partnerships can be formed through integrating efforts of the U.S. Coast Guard (USCG) with citizen science initiatives. USCG and a research group at Ohio's Bowling Green State University are entering the third year of such a partnership, in which icebreaking operations in Lake Erie using USCG Cutter Neah Bay support volunteer data collection. With two additional USCG vessels joining the program this winter season, the partnership serves as a timely and useful model for worldwide environmental research and monitoring through citizen science and government collaboration.

  20. A Stochastic Sprint in the Vague Direction of Data Science: Perspectives from a Graduate Student and Aspiring Data Scientist.

    Barberie, S. R.

    2015-12-01

    Since data science does not exist as a stand-alone discipline within major universities, learning data science, or even learning that data science exists is, for an aspiring researcher at the graduate or undergraduate level, something that only happens by accident. Here I present my own series of accidents that transformed me from a somewhat aimless graduate student into an aspiring data scientist and the challenges that that aspiration has created in fitting into traditional academic programs and finding a coherent path forward. I also present my current conundrum: with the clear intention of pursuing data science but an academic background in other subjects, where do I go from here? Do I start my education over, pursue professional certification courses and bootcamp programs, or engage in not-very-marketable self study? This career chasm creates a strange environment for aspiring data scientists where we have a destination, but not a clear road to get there. I also discuss how joining a data focused interest group called The Federation of Earth Science Information Partners (ESIP) bridged some of the gap left by Academia in allowing me to network and collaborate with real data scientists from a variety of backgrounds. Organizations like this may someday play an important role in helping aspiring data scientists find their place, although for the moment many gaps and obstacles still remain, and the path forward is far from clear.

    During the height of the Deepwater Horizon oil spill disaster, I joined a group of engineers and other scientists to discuss the evidence for an oil plume, at least 22 miles long and about a mile wide, floating 3000 feet beneath the surface of the Gulf of Mexico. As the chemist in the group, I wondered aloud about how we could exploit the aqueous solubilities of the petroleum hydrocarbons, benzene, toluene, ethylbenzene, and total xylenes to understand plume formation. I suspected the key to knowledge lay in the plume's chemical properties.

    1982-01-01

    The strength of the bond between optically contacted quartz surfaces was investigated. The Gravity Probe-B (GP-B) experiment to test the theories of general relativity requires extremely precise measurements. The quartz components of the instruments to make these measurements must be held together in a very stable unit. Optical contacting is suggested as a possible method of joining these components. The fundamental forces involved in optical contacting are reviewed and relates calculations of these forces to the results obtained in experiments.

    1979-01-01

    The present development is directed to a method for joining metal at relatively low temperatures by solid-state bonding. Planar surfaces of the metal workpieces are placed in a parallel abutting relationship with one another. A load is applied to at least one of the workpieces for forcing the workpieces together while one of the workpieces is relatively slowly oscillated in a rotary motion over a distance of about 1.degree.. After a preselected number of oscillations, the rotary motion is terminated and the bond between the abutting surfaces is effected. An additional load may be applied to facilitate the bond after terminating the rotary motion.

    2017-08-01

    Aluminum alloy sheets have been widely used to build the thin-walled structures by mechanical clinching technology in recent years. However, there is an exterior protrusion located on the lower sheet and a pit on the upper sheet, which may restrict the application of the clinching technology in visible areas. In the present study, an improved clinched joint used to join aluminum alloy sheets was investigated by experimental method. The improved clinching process used for joining aluminum alloy evolves through four phases: (a) localized deformation; (b) drawing; (c) backward extrusion; and (d) mechanical interlock forming. A flat surface can be produced using the improved clinching process. Shearing strength, tensile strength, material flow, main geometrical parameters, and failure mode of the improved clinched joint were investigated. The sheet material was compressed to flow radially and upward using a punch, which generated a mechanical interlock by producing severe localized plastic deformation. The neck thickness and interlock of the improved clinched joint were increased by increasing the forming force, which also contributed to increase the strength of the clinched joint. The improved clinched joint can get high shearing strength and tensile strength. Three main failure modes were observed in the failure process, which were neck fracture mode, button separation mode, and mixed failure mode. The improved clinched joint has better joining quality to join aluminum alloy sheets on the thin-walled structures.

  7. EUFAR training opportunities to advance European airborne research

    NASA Astrophysics Data System (ADS)

    Reusen, I.; Brenguier, J.-L.; Brown, P.; Wendish, M.

    2009-04-01

    EUFAR, EUropean Facilities for Airborne Research, is an FP7 project (http://www.eufar.net) funded by the European Commission with 33 partners that aims at providing and improving the access to European airborne facilities (i.e. aircraft, airborne instruments, data processing centres) for researchers in environmental and geo-sciences through Networking Activities, Transnational Access and Joint Research Activities. This paper reports on the training opportunities within EUFAR for European researchers. In EUFAR three types of training opportunities are offered: 1) Participate in training courses (ET-TC) 2) Join an existing field campaign (ET-EC) 3) Participate in the design of a new field campaign (ET-TA), in the frame of EUFAR Transnational Access and tutored by more experienced researchers. During the 4-year EUFAR project (2008-2012), 4 training courses covering the complete chain from acquisition to interpretation of airborne data and images will be organised during spring/summer for early-stage researchers as well as university lecturers (new in FP7 EUFAR) in airborne research. The training courses will have an equal focus on theory and practical training/demonstration and each training course will be accompanied by a "student" airborne field campaign. Participants will be trained by top-class scientists, aircraft and/or instrument operators and each participant will get the opportunity to design his/her own experiment and to participate to that flight experiment. Furthermore, researchers have the opportunity to join an existing field campaign and work with more experienced researchers, aircraft and/or instrument operators. The list of airborne field campaigns open to join and the eligibility criteria, can be consulted at the EUFAR website. Finally, researchers have the opportunity to participate in the design of a new field campaign in the frame of EUFAR Transnational Access (TA). TA provides access to either aircraft or instrumentation that are not otherwise available to applicants within their own national research funding regime. Researchers can join a host research group and participate in the design of an airborne field campaign, the flight and the analysis of the acquired data. TA is open to both experienced and inexperienced researchers. If the latter, applicants will be offered feedback from within the EUFAR community of expert scientists in order to develop and improve their proposals prior to formal review. In addition, applicants to the TA process may be offered opportunities to cluster their field campaigns with others making use of the same facility, hence providing further opportunities for interaction with more experienced users of research aircraft and instrumentation.

    In order to improve the quality of urban education, public school educators must be joined by the public, legislators, business leaders, and social planners. These individuals will need to understand public policy priorities, as well as the social, economic, and political forces which define our present environment. (Author/GC)

  18. Investigation of Thermoelectric Parameters of Bi2Te3: TEGs Assembled using Pressure-Assisted Silver Powder Sintering-Based Joining Technology

    Operation of thermoelectric generator (TEG) modules based on bismuth telluride alloys at temperatures higher than 250°C is mostly limited by the melting point of the assembly solder. Although the thermoelectric parameters of bismuth telluride materials degrade for temperatures >130°C, the power output of the module can be enhanced with an increase in the temperature difference. For this, a temperature-stable joining technique, especially for the hot side of the modules, is required. Fabrication and process parameters of TEG modules consisting of bismuth telluride legs, alumina ceramics and copper interconnects using a joining technique based on pressure-assisted silver powder sintering are described. Measurements of the thermal force, electrical resistance, and output power are presented that were performed for hot side module temperatures up to 350°C and temperature differences higher than 300°C. Temperature cycling and results measured during extended high-temperature operation are addressed.

    In order to save weight and costs, different materials can be combined within one component. In the novel process chain being developed within the Collaborative Research Centre (CRC) 1153, joined semi-finished workpieces are used to produce hybrid solid components with locally adapted properties. Different materials are joined in an initial step before the forming process takes place. Hereby, the quality of the joining zone is improved by means of the thermo-mechanical treatment during the forming and machining processes. The lateral angular co-extrusion (LACE) approach is used to produce semi-finished workpieces because it allows for the production of coaxial semi-finished products consisting of aluminium and steel. In the further process chain, these semi-finished products are processed into hybrid bearing bushings with locally adapted properties by die forging. In the scope of this work, numerical investigations of the co-extrusion of aluminium-steel compounds were carried out using finite element (FE) simulation in order to examine the influence of the process parameters on the co-extrusion process. For this purpose, the relevant material properties of the aluminium alloy EN AW-6082 were determined experimentally and subsequently implemented in the numerical model. The obtained numerical model was used to study the impact of different ram speeds, press ratios and billet temperatures on the resulting extrusion forces and the material flow. The numerical results have been validated using force-time curves obtained from experimental extrusion tests carried out on a 2.5 MN laboratory extrusion press.

    James Barrilleaux is the assistant chief pilot for ER-2s in the Flight Crew Branch of NASA's Dryden Flight Research Center, Edwards, California. The ER-2s--civilian variants of the military U-2S reconnaissance aircraft--are part of NASA's Airborne Science program. The ER-2s can carry airborne scientific payloads of up to 2,600 pounds to altitudes of about 70,000 feet to investigate such matters as earth resources, celestial phenomena, atmospheric chemistry and dynamics, and oceanic processes. Barrilleaux has held his current position since February 1998. Barrilleaux joined NASA in 1986 as a U-2/ER-2 pilot with NASA's Airborne Science program at Ames Research Center, Moffett Field, California. He flew both the U-2C (until 1989) and the ER-2 on a wide variety of missions both domestic and international. Barrilleaux flew high-altitude operations over Antarctica in which scientific instruments aboard the ER-2 defined the cause of ozone depletion over the continent, known as the ozone hole. He has also flown the ER-2 over the North Pole. Barrilleaux served for 20 years in the U.S. Air Force before he joined NASA. He completed pilot training at Reese Air Force Base, Lubbock, Texas, in 1966. He flew 120 combat missions as a F-4 fighter pilot over Laos and North Vietnam in 1970 and 1971. He joined the U-2 program in 1974, becoming the commander of an overseas U-2 operation in 1982. In 1983, he became commander of the squadron responsible for training all U-2 pilots and SR-71 crews located at Beale Air Force Base, Marysville, California. He retired from the Air Force as a lieutenant colonel in 1986. On active duty, he flew the U-2, F-4 Phantom, the T-38, T-37, and the T-33. His decorations included two Distinguished Flying Crosses, 12 Air Medals, two Meritorious Service Medals, and other Air Force and South Vietnamese awards. Barrilleaux earned a bachelor of science degree in chemical engineering from Texas A&M University, College Station, in 1964 and a master of science degree in systems management from the University of Southern California in 1979. He has accumulated more than 5,800 hours of flying time over a period of 33 years and is currently the oldest active U-2/ER-2 pilot.

    These are the Proceedings of the Corfu Summer Institute on Elementary Particle Physics (CORFU2005) (http://corfu2005.physics.uoi.gr), which took place in Corfu, Greece from 4 - 26 September 2005. The Corfu Summer Institute has a very long, interesting and successful history, some elements of which can be found in http://www.corfu-summer-institute.gr. In short, the Corfu Meeting started as a Summer School on Elementary Particle Physics (EPP) mostly for Greek graduate students in 1982 and has developed into a leading international Summer Institute in the field of EPP, both experimental and theoretical, providing in addition a very rich outreach programme to teachers and school students. The CORFU2005 Summer Institute on EPP, although based on the general format that has been developed and established in the Corfu Meetings during previous years, is characterized by the fact that it was a full realization of a new idea, which started experimentally in the previous two Corfu Meetings. The successful new ingredient was that three European Marie Curie Research Training Networks decided to hold their Workshops in Corfu during September 2005 and they managed to coordinate the educational part of their meetings to a huge Summer School called `The 8th Hellenic School on Elementary Particle Physics' (4 - 11 September). The European Networks which joined forces to materialize this project and the corresponding dates of their own Workshops are:

  3. The Third Generation as a Probe for New Physics: Experimental and Technological Approach (4 - 11 September)
  4. The Quest for Unification Theory Confronts Experiment (11 - 18 September)
  5. Constituents Fundamental Forces and Symmetries of the Universe (20 - 26 September)
    6. To these Workshops has been added a Satellite one called `Noncommutative Geometry in Field and String Theory', and some extra speakers have been invited to complement the full programme of CORFU2005, some of whom have integrated into the Workshop's programme. The result was indeed very successful! An impressive aspect is that the CORFU2005 had the most massive participation so far attracting around 350 scientists. Among them around 200 young scientists (100 graduate students and 100 post doctoral scientists) and around 150 senior scientists. Therefore, among others, CORFU2005 hosted one of the largest Summer Schools in our field. Internationally leading scientists have been gathered in the CORFU2005 in the various Workshops and the School and have created a stimulating scientific atmosphere for themselves and for the young scientists. The contributions of all speakers can be found in http://corfu2005.physics.uoi.gr. Most of them have contributed to the present proceedings, while the contributions of the last week can be found in Fortsch. Phys. 54, Issue 5 - 6 (May 2006). In parallel to the main scientific programme a very interesting, rich and successful outreach programme was held in collaboration with the local Department of the Greek Physical Society and the Laboratory of Physical Science in Corfu (EKFE). The success of the CORFU2005 was the best advertisement concerning the long standing efforts to establish the `European Institute of Science and their Applications', which eventually was founded last spring in Corfu. The new Institute hopes to be the permanent extension of the Corfu Summer Institutes on EPP and has an additional aim to upgrade them in the sense that the attracted first class scientists would produce locally a significant research output. We would like to thank everybody very much who contributed to the success of CORFU2005. We would like specifically to thank all speakers and organizers, the conference secretary and the school officer (please consult http://corfu2005.physics.uoi.gr) and the group of graduate students who helped in various ways and contributed in a very significant manner in the success of CORFU2005. In addition we would like to thank our sponsors, whose contribution made possible the CORFU2005:

    One afternoon Benoit invited me to a master's tea in his college at Yale. He and a group of colleagues discussed opera, the distribution of galaxies, Hokusai's art, Stoppard's Arcadia, many other topics. Despite the conversation's swerves, Benoit contributed detailed opinions to each new direction. When he excused himself to speak with someone on the other side of the room, a diminuitive Cuban poet who joined the group late turned to me, clearly Benoit's guest, and asked, "Who is that enormous man?" Before I could reply, another said, "Oh, that's Benoit Mandelbrot. He reinvented geometry." "Ah, a scientist. Then why does he know opera and art?"...

  22. Is cognitive science usefully cast as complexity science?

    Van Orden, Guy; Stephen, Damian G

    2012-01-01

    Readers of TopiCS are invited to join a debate about the utility of ideas and methods of complexity science. The topics of debate include empirical instances of qualitative change in cognitive activity and whether this empirical work demonstrates sufficiently the empirical flags of complexity. In addition, new phenomena discovered by complexity scientists, and motivated by complexity theory, call into question some basic assumptions of conventional cognitive science such as stable equilibria and homogeneous variance. The articles and commentaries that appear in this issue also illustrate a new debate style format for topiCS. Copyright © 2011 Cognitive Science Society, Inc.

    Radar sounder instruments orbiting Mars have looked beneath the Martian surface and opened up the third dimension for planetary exploration. The technique's success is prompting scientists to think of all the other places in the Solar System where they would like to use radar sounders.

    The first radar sounder at Mars was the Mars Advanced Radar for Subsurface and Ionospheric Sounding (MARSIS) on the European Space Agency's Mars Express Orbiter. It has been joined by the complementary Shallow Subsurface Radar (SHARAD), operating at a different wavelength aboard NASA's Mars Reconnaissance Orbiter. The data in this animation are from SHARAD.

    The design of programs in support of a strong, diverse, and inclusive scientific workforce and academe requires numerous difficult conversations about sensitive topics such as the challenges scientists can face in their professional development. Theatre can be an interactive and effective way to foster discussion around such subjects. This article examines the implementation and benefits of such interactive strategies in different contexts, including the benefits of getting early career academics and professionals talking about some of the situations that women and underrepresented minorities face in the workplace, while allowing more seasoned professionals and colleagues to join in the conversation.

    Extra-oral traction appliances were introduced more than a century ago and continue to be used to produce orthopaedic and/or dental changes in the maxilla. While force systems produced by asymmetric outer bows have been studied extensively, the force systems produced by asymmetric inner bows have been overlooked. To analyse the forces acting on the maxillary first molars: when the size of one bayonet bend is increased; when the point of application of the distalising force on the inner bow is moved to one side; when one molar is displaced palatally. Four FEM models of cervical headgear attached to maxillary first molars were designed in SolidWorks 2010 and transferred to an ANSYS Workbench Ver. 12.1. Model 1, each molar was 23 mm from the midpalatal line and the inner bow was symmetrical; Model 2, the left molar was displaced 4 mm towards the midpalatal line and the inner bow was symmetrical; Model 3, the molars were equidistant (23 mm) from the midpalatal line, but the left molar was engaged by a 2 mm larger bayonet bend; Model 4, the molars were equidistant (23 mm) from the midpalatal line but the join between the inner and outer bows was displaced 2 mm towards the left molar. In all FEM models, a 2N force was applied to the inner bow at the join between inner and outer bows and the energy transmitted to the teeth and the von Mises stresses on the molar PDLs were assessed. There were marked differences in the strain energy on the teeth and the von Mises stresses on their PDLs. A 14 to 20 per cent increase in energy and force was produced on the tooth closer to the symmetric plane of the headgear. In addition, the increase in energy produced a 30 to 62 per cent increase in the von Mises stresses within the PDLs. Small asymmetries in molar position, the size of a bayonet bend and the point of application of a force on an inner bow resulted in asymmetrical forces on the molars. These forces were higher on the molar closer to the symmetric plane of the headgear.

    IGAC’s mission is to facilitate atmospheric chemistry research towards a sustainable world. This is achieved through IGAC’s three focal activities: fostering community, building capacity, and providing leadership. A key component to achieving IGAC’s mission is its developing early career program. These scientists join an international network early in their career that puts the cogs in motion to further facilitate atmospheric chemistry research at an international level for years to come. IGAC’s Science Conference is a primary mechanism for IGAC to build cooperation and disseminate scientific information across its international community. The first IGAC Science Conference was held in 1993 in Eilat,more » Israel. Since then, IGAC has successfully held fourteen science conferences, consistently becoming a biennial conference starting in 2002. The biennial IGAC Science Conference is regarded as THE international conference on atmospheric chemistry and participation in the conference is typically in the range of 350-650 participants. Since 2004, IGAC has included an Early Career Scientists Program as part of the conference to foster the next generation of scientists. IGAC believes, and has seen, that by allowing scientists to form an international network of colleagues early in their career that future international collaborations in atmospheric chemistry are enhanced. The 2016 IGAC Science Conference Early Career Program consisted of numerous events throughout the week giving these scientists the opportunity to not only create a community amongst themselves, but to also engage and build relationships with senior scientists. In order to support the Early Career Scientists Program, IGAC sought funding from international, regional and local organizations to provide Travel Grants to the conference based on an assessment of both need and merit. This conference summary reports on outcomes of the 2016 IGAC Science Conference and the Early Career Program, which included early career travel grants funded by this DOE grant.« less

  32. Identifying Basic Factors for Communal Prosperity - Space Technologies are Bridging this Gap

    There are many aspects, which are important for maintaining environmentally clean and safe conditions for a healthy and economically self-sufficient community. This problem was somewhat of a lesser concern in earlier days because many communities were small, isolated and solely dependent upon their owners or landlords. Due to an astronomical growth in human population within the last century, extensive use of combustion technologies, and changing environmental conditions has resulted in scarcity of natural resources. In reality, the societal sustainability issues are becoming much more acute and complex. Therefore, the researchers and social scientists are joining forces to address these topics and find solutions to many contentious areas such as public health and diseases, water resources, agriculture production, survivability during and after the natural disasters, energy needs and many others. Forthrightly speaking, there is no canned solution or a methodology to go about solving these issues since the magnitude and complexity of these issues are multi-dimensional and are further inter-locked with other areas. A common sense tells us that we need data, resources and technologies to begin addressing these problems. This is where space observations have provided us with tremendous information and opportunities, which are of great assets to the science, economist, and social scientists. This paper specifically addresses what are critical areas for a successful societal sustainability and growth; and how can we take advantage of multiple sensors and models already in existence. Increasing our knowledge of the home planet, via amplified set of observations, is certainly a right step in a right direction. Furthermore, this is a pre-requisite in understanding multiple hazard phenomena's. This paper further examines various space sensors and observing architectures that can be useful specifically in addressing some of these complex issues. The ultimate goal is to serve the society by providing such valuable information so the decision makers can take full advantage in making timely societal decisions.

  33. [Improvement of hygiene and the combat of epidemics as Russian state concerns during World War I: Prince Alexander von Oldenburg and the POWs of the Central Powers in Russia].

    When Russia joined the war against the Central Powers in 1914, she immediately faced problems of public health care among the masses of people who were forced to move across far distances in the country: soldiers, refugees, and prisoners of war. Because of poor organisation and the unexpectedly long duration of the war, the POWs fared worst of all war victims in Russia. Subjected to an overstrained military organisation in the rear, the fate of this broadly neglected group illustrates how and with what success Russia strove to meet its deficiencies in administrative structure during wartime. The "Evacuation and Sanitation Section" was put under the command of a member of the Imperial family, Prince Alexander of Oldenburg, a high ranking official of German origin. This amateur scientist and initiator of medical institutions was an energetic and courageous personality who became vital for the fate of millions of POWs in epidemic-stricken Russia. The role of this "silent" ally of the German and Austro-Hungarian governments has hitherto been unknown. Newly found sources in Russian archives now shed an interesting light on a weak spot of Russia's administration and a generally neglected chapter of the history of medicine, the handling of epidemics and of deficits in hygiene.

  1. Ambient belonging: how stereotypical cues impact gender participation in computer science.

    PubMed

    Cheryan, Sapna; Plaut, Victoria C; Davies, Paul G; Steele, Claude M

    2009-12-01

    People can make decisions to join a group based solely on exposure to that group's physical environment. Four studies demonstrate that the gender difference in interest in computer science is influenced by exposure to environments associated with computer scientists. In Study 1, simply changing the objects in a computer science classroom from those considered stereotypical of computer science (e.g., Star Trek poster, video games) to objects not considered stereotypical of computer science (e.g., nature poster, phone books) was sufficient to boost female undergraduates' interest in computer science to the level of their male peers. Further investigation revealed that the stereotypical broadcast a masculine stereotype that discouraged women's sense of ambient belonging and subsequent interest in the environment (Studies 2, 3, and 4) but had no similar effect on men (Studies 3, 4). This masculine stereotype prevented women's interest from developing even in environments entirely populated by other women (Study 2). Objects can thus come to broadcast stereotypes of a group, which in turn can deter people who do not identify with these stereotypes from joining that group.

  3. Growing Your Career through Volunteering and Leadership

    NASA Astrophysics Data System (ADS)

    O'Riordan, C. A.; Meth, C.

    2007-12-01

    From giving your first paper at a scientific meeting to chairing committees that make multi-million dollar decisions, scientific organizations provide critical opportunities for growing your career. Many organizations support student activities by providing travel grants and fellowships - an important first step towards joining the larger scientific community. Beyond these standard opportunities, organizations also provide opportunities for students interested in gaining leadership experience, a skill not typically acquired in graduate science programs. For example, the Consortium for Leadership's Schlanger Ocean Drilling Fellowship provides research funds to graduate students, but also introduces the fellows to the communication skills needed to become successful members of their scientific community. Beyond student opportunities, volunteering provides mid-career and established scientists further experience in leadership. Opportunities exist in advising government science policy, guiding large-scale research programs, organizing large scientific meetings, and serving on non-profit boards. The variety of volunteer and leadership opportunities that are available give scientists at all stages of their career a chance to expand and diversify their experience, leading to new successes.

  4. Communicating the Science of Global Warming — the Role of Astronomers

    NASA Astrophysics Data System (ADS)

    Bennett, Jeffrey

    2018-06-01

    Global Warming is one of the most important and issues of our times, yet it is widely misunderstood among the general public (and politicians!). The American Astronomical Society has already joined many other scientific organizations in advocating for action on global warming (by supporting the AGU statement on global warming), but we as astronomers can do much more. The high public profile of astronomy gives us a unique platform — and credibility as scientists — for doing our part to educate the public about the underlying science of global warming. And while astronomers are not climate scientists, we use the same basic physics, and many aspects of global warming science come directly from astronomy, including the ways in which we measure the heat-absorbing potential of carbon dioxide and the hard evidence of greenhouse warming provided by studies of Venus. In this session, I will briefly introduce a few methods for communicating about global warming that I believe you will find effective in your own education efforts.

  5. First a hero of science and now a martyr to science: the James Watson Affair - political correctness crushes free scientific communication.

    PubMed

    Charlton, Bruce G

    2008-01-01

    In 2007 James D. Watson, perhaps the most famous living scientist, was forced to retire from his position and retreat from public life in the face of international mass media condemnation following remarks concerning genetically-caused racial differences in intelligence. Watson was punished for stating forthright views on topics that elite opinion has determined should be discussed only with elaborate caution, frequent disclaimers, and solemn deference to the currently-prevailing pieties. James Watson has always struck many people as brash; however this blunt, truth-telling quality was intrinsic to his role in one of the greatest scientific discoveries. Much more importantly than 'good manners', Watson has consistently exemplified the cardinal scientific virtue: he speaks what he understands to be the truth without regard for the opinion of others. The most chilling aspect of the Watson Affair was the way in which so many influential members of the scientific research community joined the media condemnation directed against Watson. Perhaps the most egregious betrayal of science was an article by editorialists of the premier UK scientific journal Nature. Instead of defending the freedom of discourse in pursuit of scientific truth, Nature instead blamed Watson for being 'crass' and lacking 'sensitivity' in discussing human genetic differences. But if asked to choose between the 'sensitive' editors of Nature or the 'crass' genius of James D. Watson, all serious scientists must take the side of Watson. Because when a premier researcher such as Watson is hounded from office by a vicious, arbitrary and untruthful mob; all lesser scientists are made vulnerable to analogous treatment at the whim of the media. A zealous and coercive brand of 'political correctness' is now making the biological truth of human genetic differences intolerably difficult to discover and discuss in US and UK. This needs to change. My hope is that truth will prevail over political correctness and James Watson will not just be exonerated but vindicated as an exemplar of the true morality of science: that scientific communication needs to be allowed to be clear, direct - even crass - in the pursuit of truth. James Watson has been a hero of science for the achievements of his career, and also a martyr for science at the end of his career.

  6. From Supernovae To Equatorial Ionosphere, Following a Tortuous Path Through Computer Sciences, Oceanography, and Much, Much More

    NASA Astrophysics Data System (ADS)

    de La Beaujardiere, O.

    2002-12-01

    From as early as I can remember, I always wanted to be a scientist. My interests were oriented towards cataclysmic and catastrophic events. I first wanted to study volcanoes, then earthquakes. As I ended my PhD, my interests had gone a little higher, towards supernovae and the Crab Nebula. This was in Paris. I then immigrated to the US. My first job in the US was in computer sciences. I joined a team who made one of the first computer movies. I then switched fields once more. I went into ionospheric physics, where I stayed for more than 2 decades. I then did two "tours of duty" at National Sciences Foundation. I was first in the Magnetospheric Program. Then I started a multidisciplinary program that covered all sciences related to the arctic - from the bottom o f the ocean to the confines of the magnetosphere, passing through biology, glaciology, etc. Presently, I lead a team of about 20 scientists at the Air Force Research Laboratory. We work on basic and applied ionospheric sciences problems as they relate to communications and navigation. As a woman scientist, the hardest obstacle I had to overcome was probably the permanent guilt of not staying home with my children. I raised 3 boys, and, although they are happy, successful and well adjusted, I continue to feel guilt about not staying home for them, and working so long hours and with so much intensity. When they were small, society was not too accepting of working mothers. In one of my kids' first grade class, he was the only child whose mother was working. As a teenager I also had to overcome rejection from boys who "could not stand" girls who studied science. My own father was not too encouraging to continue studies, warning me that women who are too bright have a hard time finding husbands. One University professor told the class that women were wasting taxpayers' money since they would never put their degree to use. My greatest support was my husband, always there, sharing chores, and understanding my ups and downs. The saying that the difficult period in a woman's life is only between the ages of 7 and 70 gives me solace. I can't wait to be 70.

Latimer joined NASA in March 2007 and will fly the T38, T-34, G-III, C-17 and the "Ikhana" Predator B. Latimer is Dryden's first female research test pilot. Prior to joining NASA, Latimer was on active duty with the U.S. Air Force. She has accumulated more than 5,000 hours of military and civilian flight experience in 30 aircraft. Latimer's first association with NASA was while attending graduate school at George Washington University, Washington, D.C. Her studies included work with the Joint Institute for the Advancement of Flight Sciences at NASA's Langley Research Center, Hampton, Va. She flew an Air Force C-17 during a 2005 NASA study to reduce aircraft noise. A team of California Polytechnic State University students and Northrop Grumman personnel were stationed on Rogers Dry Lake located at Edwards Air Force Base, Calif., to record the noise footprint of the aircraft as it made various landing approaches to Edwards' runway. Latimer completed undergraduate pilot training at Reese Air Force Base, Texas, in 1990. She remained at Reese as a T-38 instructor pilot until 1993. She was assigned as a C-141 aircraft commander at McCord Air Force Base, Tacoma, Wash., until 1996. Latimer graduated from the U.S. Air Force Test Pilot School at Edwards in Class 96B. She served as a C-17 and C-141 experimental test pilot at Edwards until 2000. She then became the chief of the Performance Branch and a T-38 instructor pilot at The Air Force Test Pilot School. She returned to McCord in 2002, where she was a C-17 aircraft commander and the operations officer for the 62nd Operations Support Squadron. In 2004, Latimer became the commander of Edwards' 418th Flight Test Squadron and director of the Global Reach Combined Test Force. Following that assignment, she deployed to Iraq as an advisor to the Iraqi Air Force. Her last active duty tour was as an instructor a

  9. On disciplinary fragmentation and scientific progress.

    2015-01-01

    Why are some scientific disciplines, such as sociology and psychology, more fragmented into conflicting schools of thought than other fields, such as physics and biology? Furthermore, why does high fragmentation tend to coincide with limited scientific progress? We analyzed a formal model where scientists seek to identify the correct answer to a research question. Each scientist is influenced by three forces: (i) signals received from the correct answer to the question; (ii) peer influence; and (iii) noise. We observed the emergence of different macroscopic patterns of collective exploration, and studied how the three forces affect the degree to which disciplines fall apart into divergent fragments, or so-called "schools of thought". We conducted two simulation experiments where we tested (A) whether the three forces foster or hamper progress, and (B) whether disciplinary fragmentation causally affects scientific progress and vice versa. We found that fragmentation critically limits scientific progress. Strikingly, there is no effect in the opposite causal direction. What is more, our results shows that at the heart of the mechanisms driving scientific progress we find (i) social interactions, and (ii) peer disagreement. In fact, fragmentation is increased and progress limited if the simulated scientists are open to influence only by peers with very similar views, or when within-school diversity is lost. Finally, disciplines where the scientists received strong signals from the correct answer were less fragmented and experienced faster progress. We discuss model's implications for the design of social institutions fostering interdisciplinarity and participation in science.

    A computer-oriented procedure for solving the dynamic force analysis problem for general planar mechanisms is presented. This paper provides position analysis, velocity analysis, acceleration analysis and force analysis of six bar mechanism with variable topology approach. Six bar mechanism is constructed by joining two simple four bar mechanisms. Initially the position, velocity and acceleration analysis of first four bar mechanism are determined by using the input parameters. The outputs (angular displacement, velocity and acceleration of rocker)of first four bar mechanism are used as input parameter for the second four bar mechanism and the position, velocity, acceleration and forces are analyzed. With out-put parameters of second four-bar mechanism the force analysis of first four-bar mechanism is carried out.

    Zirconia powder in nanometers can be fabricated into inter-joined abutment of dental implant system with the injection shaping technique. This study was to detect the resistance of inter-joined zirconia abutment with different angle loading for clinical applications. The inter-joined abutments were shaped with the technique of injection of zirconia powder in nanometers. Sixty Osstem GSII 5 × 10 mm implants were used with 30 zirconia abutments and 30 Osstem GSII titanium abutments for fixation using 40 N torque force. The loading applications included 90°, 30°, and 0° formed by the long axis of abutments and pressure head of universal test machine. The fracture resistances of zirconia and titanium abutments were documented and analyzed. The inter-joined zirconia abutments were assembled to the Osstem GSII implants successfully. In the 90° loading mode, the fracture resistance of zirconia abutment group and titanium abutment group were 301.5 ± 15.4 N and 736.4 ± 120.1 N, respectively. And those in the 30° groups were 434.7 ± 36.1 N and 1073.1 ± 74 N, correspondingly. Significant difference in the two groups was found using t-test and Wilcoxon test. No damage on the abutments of the two groups but S-shaped bending on the implants was found when the 0° loading was 1300-2000 N. Through the assembly of Zirconia abutments and implants, all the components presented sufficient resistance acquired for the clinical application under loadings with different angle. © 2012 John Wiley & Sons A/S.

  19. Physician-scientist, heal thyself . . .

    PubMed

    Marks, Andrew R

    2007-01-01

    Historically, physician-scientists have had dual roles in caring for patients and in performing investigative research that could potentially lead to new diagnostics and therapeutics. Physician-scientists conducted teaching rounds in the hospital, surrounded by eager house staff and medical students, and were often avidly pursued as the most important sources of new knowledge for trainees. But alas, times have changed. Now physician-scientists are rarely seen in the hospital; they are most often spotted at their desks tapping out yet another grant application. Most struggle to find the time to mentor students and clinical trainees, let alone to care for patients in the hospital, even though these interactions are often the motivating forces for scientific creativity.

  20. Improving Self-Pierce Rivet Performance through Processing and Alloy Development

    NASA Astrophysics Data System (ADS)

    Van Hall, Stephen N.

    Spot welding has been used to join steel sheet material in the past during automotive manufacturing. The increasing use of aluminum and mixed materials to achieve continually increasing fuel economy standards requires mechanical joining methods to provide adequate impact performance. One such mechanical joining process is self-pierce riveting (SPR). Self-pierce riveting has grown in popularity in recent years due to fast cycle times, high static strength and fatigue performance as well as the ability to join many different sheet material combinations. Self-pierce rivet utilization has become limited due to the material properties of the rivet in two main areas: the joining of high-strength sheet material and joining of multiple sheet material combinations using a single rivet geometry, referred to as commonization. Two specific case studies have been developed to assess the failures that occur and evaluate potential solutions: joining of press-hardened steel (PHS) to Al6111 and improved commonization ability using a two layer aluminum joint that is currently joined with a specialized rivet. Riveting trials have been performed on each of the two case studies using cold forged rivets produced from 10B37 steel that has been heat-treated through a quench and temper process to a range of hardness levels to evaluate the failures that occur within the rivet. The failures occur with two different modes: buckling of the rivet at hardness values below 550 HV when joining PHS and Al6111 and fractures that occur in the rivet tail at hardness values above 550 HV during joining in each of the case studies under evaluation. The fractures have been attributed to a high degree of hoop strain that forms when the rivets are flared beyond the design specifications. A method to replicate the rivet flaring procedure under laboratory conditions has been developed by flaring the rivets through various strain paths to induce a hoop strain and the resultant fractures. The flaring method shows the ability to replicate the types of fractures that were observed during joining attempts while monitoring applied force, crosshead displacement and strain at the point of fracture at the rivet tail using digital image correlation. Alternative alloys including 4130, 4340 and 5160 were evaluated alongside 10B37 for improved performance after quenching and tempering, austempering and after being intentionally decarburized to varying degrees. The heat-treatments were evaluated through microscopy, fractography, rivet flaring and joining attempts for each case study and alloy under investigation. All of the alternative alloys showed no significant performance gains after being quenched and tempered or austempered. However, hoop strain to failure during flaring was increased between 2-4x after the rivets had been intentionally decarburized. The intentionally decarburized rivets were evaluated through joining trials and provided successful joining for each of the case studies under investigation using 10B37 rivets. Rivets produced from 4340 and 5160 also showed instances of success during joining attempts. The Cockroft and Latham failure criterion was evaluated in regards to rivet flaring through the development of finite element simulations using Abaqus. The Cockroft and Latham failure criterion was able to successfully predict the location of riveting fractures through multiple strain paths, rivet geometries and microstructures. Cockroft and Latham values from tensile tests of 10B37 wire led to an underestimate of the strain to failure when compared to the rivet flaring process for quenched and tempered rivets but was very similar to the strain predicted for rivets that had been intentionally decarburized.

  1. Causal reasoning with forces

    PubMed Central

    Wolff, Phillip; Barbey, Aron K.

    2015-01-01

    Causal composition allows people to generate new causal relations by combining existing causal knowledge. We introduce a new computational model of such reasoning, the force theory, which holds that people compose causal relations by simulating the processes that join forces in the world, and compare this theory with the mental model theory (Khemlani et al., 2014) and the causal model theory (Sloman et al., 2009), which explain causal composition on the basis of mental models and structural equations, respectively. In one experiment, the force theory was uniquely able to account for people's ability to compose causal relationships from complex animations of real-world events. In three additional experiments, the force theory did as well as or better than the other two theories in explaining the causal compositions people generated from linguistically presented causal relations. Implications for causal learning and the hierarchical structure of causal knowledge are discussed. PMID:25653611

    2004-01-01

    This image composite shows two of the Mars Exploration Rover Opportunity's magnets, the 'capture' magnet (upper portion of left panel) and the 'filter' magnet (lower portion of left panel). Scientists use these tools to study the origins of martian dust in the atmosphere. The left panel was taken by the rover's panoramic camera. The four panels to the right, taken by the microscopic imager, show close-up views of the two magnets. The bull's-eye appearance of the capture magnet is a result of alternating magnetic fields, which are used to increase overall magnetic force. The filter magnet lacks these alternating fields and consequently produces a weaker magnetic force. This weaker force selectively attracts only strong magnetic particles.

    Scientists were surprised by the large dark particles on the magnets because airborne particles are smaller in size. They theorize that these spots might be aggregates of small particles that clump together in a magnetic field.

    2018-01-01

    Welcome to the Sixth Annual NASA Ames Research Center, Space Science and Astrobiology Jamboree at NASA Ames Research Center (ARC). The Space Science and Astrobiology Division consists of over 60 Civil Servants, with more than 120 Cooperative Agreement Research Scientists, Post-Doctoral Fellows, Science Support Contractors, Visiting Scientists, and many other Research Associates. Within the Division there is engagement in scientific investigations over a breadth of disciplines including Astrobiology, Astrophysics, Exobiology, Exoplanets, Planetary Systems Science, and many more. The Division's personnel support NASA spacecraft missions (current and planned), including SOFIA, K2, MSL, New Horizons, JWST, WFIRST, and others. Our top-notch science research staff is spread amongst three branches in five buildings at ARC. Naturally, it can thus be difficult to remain abreast of what fellow scientific researchers pursue actively, and then what may present and/or offer regarding inter-Branch, intra-Division future collaborative efforts. In organizing this annual jamboree, the goals are to offer a wholesome, one-venue opportunity to sense the active scientific research and spacecraft mission involvement within the Division; and to facilitate communication and collaboration amongst our research scientists. Annually, the Division honors one senior research scientist with a Pollack Lecture, and one early career research scientist with an Outstanding Early Career Space Scientist Lecture. For the Pollack Lecture, the honor is bestowed upon a senior researcher who has made significant contributions within any area of research aligned with space science and/or astrobiology. This year we are pleased to honor Linda Jahnke. With the Early Career Lecture, the honor is bestowed upon an early-career researcher who has substantially demonstrated great promise for significant contributions within space science, astrobiology, and/or, in support of spacecraft missions addressing such disciplines. This year we are pleased to honor Amanda Cook. We hope that you will make time to join us for the day in meeting fellow Division members, expanding knowledge of our activities, and creating new collaborations within the Space Science and Astrobiology Division.

  3. Alleviation of whirl-flutter on a joined-wing tilt-rotor aircraft configuration using active controls

    NASA Technical Reports Server (NTRS)

    Vanaken, Johannes M.

    1991-01-01

    The feasibility of using active controls to delay the onset of whirl-flutter on a joined-wing tilt rotor aircraft was investigated. The CAMRAD/JA code was used to obtain a set of linear differential equations which describe the motion of the joined-wing tilt-rotor aircraft. The hub motions due to wing/body motion is a standard input to CAMRAD/JA and were obtained from a structural dynamics model of a representative joined-wing tilt-rotor aircraft. The CAMRAD/JA output, consisting of the open-loop system matrices, and the airframe free vibration motion were input to a separate program which performed the closed-loop, active control calculations. An eigenvalue analysis was performed to determine the flutter stability of both open- and closed-loop systems. Sensor models, based upon the feedback of pure state variables and based upon hub-mounted sensors, providing physically measurable accelerations, were evaluated. It was shown that the onset of tilt-rotor whirl-flutter could be delayed from 240 to above 270 knots by feeding back vertical and span-wise accelerations, measured at the rotor hub, to the longitudinal cyclic pitch. Time response calculations at a 270-knot cruise condition showed an active cyclic pitch control level of 0.009 deg, which equates to a very acceptable 9 pound active-control force applied at the rotor hub.

  4. Fabrication and characterization of joined silicon carbide cylindrical components for nuclear applications

    NASA Astrophysics Data System (ADS)

    Khalifa, H. E.; Deck, C. P.; Gutierrez, O.; Jacobsen, G. M.; Back, C. A.

    2015-02-01

    The use of silicon carbide (SiC) composites as structural materials in nuclear applications necessitates the development of a viable joining method. One critical application for nuclear-grade joining is the sealing of fuel within a cylindrical cladding. This paper demonstrates cylindrical joint feasibility using a low activation nuclear-grade joint material comprised entirely of β-SiC. While many papers have considered joining material, this paper takes into consideration the joint geometry and component form factor, as well as the material performance. Work focused specifically on characterizing the strength and permeability performance of joints between cylindrical SiC-SiC composites and monolithic SiC endplugs. The effects of environment and neutron irradiation were not evaluated in this study. Joint test specimens of different geometries were evaluated in their as-fabricated state, as well as after being subjected to thermal cycling and partial mechanical loading. A butted scarf geometry supplied the best combination of high strength and low permeability. A leak rate performance of 2 × 10-9 mbar l s-1 was maintained after thermal cycling and partial mechanical loading and sustained applied force of 3.4 kN, or an apparent strength of 77 MPa. This work shows that a cylindrical SiC-SiC composite tube sealed with a butted scarf endplug provides out-of-pile strength and permeability performance that meets light water reactor design requirements.

    This article describes the distinguished career of Andrew M. Sessler, the visionary former director of the Lawrence Berkeley National Laboratory (LBNL), one of the most influential accelerator physicists, and a strong, dedicated human-rights activist. Andy died on 17 April 2014 from cancer at age 85. He grew up in New York City, and attended Harvard (BA in Mathematics, 1949) and then Columbia (PhD in Physics, 1953.) After an NSF postdoc at Cornell with Hans Bethe and a stint on the faculty at the Ohio State University in 1954-59, he joined the Lawrence Radiation Laboratory (now LBNL) in 1959, and spent the remainder of his career there. Although Andy l his mark on several areas of physics, including nuclear structure theory, elementary-particle physics, and many-body problems, his lasting and most important contributions came from his efforts in accelerator physics and engineering, to which he devoted most of his life's work. In collaboration with his colleagues of the legendary Midwestern Universities Research Association, he developed theories for the RF acceleration process and the collective instability phenomena, helping to realize the colliding-beam accelerators with which most of the high-energy-physics discoveries of the last few decades have been made. His work in connection with the free-electron-laser (FEL) amplifier for high-power microwave generation constructed at the Lawrence Livermore National Laboratory anticipated the optical-guiding and the self-amplified spontaneous-emission principles, upon which the success of the X-ray FELs as the fourth-generation light sources is based. Throughout his career Andy made major contributions to issues related to the impact of science and technology on society. He helped usher in a new era of research on energy efficiency and sustainable-energy technology and was instrumental in building the research agendas in those areas for the Atomic Energy Commission (AEC) and later the Department of Energy. With a lifelong interest in promoting the human rights of scientists, Andy was instrumental in initiating the American Physical Society's Committee on International Freedom of Scientists and in raising funds to endow the APS Andrei Sakharov Prize. He and Moishe Pripstein cofounded Scientists for Sakharov, Orlov, and Sharansky; the group's protests along with those of other groups led to the release of the three Soviet dissidents. More importantly, Andy's voice and example became a major force in helping call the world's attention to the plight of scientists trapped in places where their human rights and their ability to do science were severely compromised. Andy received many honors, including the AEC's Ernest Orlando Lawrence Award in 1970, the APS's Dwight Nicholson Medal in 1994, and the Enrico Fermi Award from the US Department of Energy in 2014.

    A survey of 2,051 pupils between Grade 4 and Grade 7 in 2003 showed that social influence or encouragement to substance use was a significant determinant of substance use risk, controlling for prior substance use and other backgrounds. Contextual stress or unhappiness among parents, classmates, and other people around operated jointly with social influence to promote substance use risk. This finding accords with a dovetail model about the extra influence due to the joining of force and receptivity to the force. Further research is necessary to corroborate the present findings obtained from a place and a time.

    This article describes the perspectives of hearing device manufacturers regarding the exciting developments that the Internet makes possible. Specifically, it proposes to join forces toward interoperability and standardization of Internet and audiology. A summary of why such a collaborative effort is required is provided from historical and scientific perspectives. A roadmap toward interoperability and standardization is proposed. Information and communication technologies improve the flow of health care data and pave the way to better health care. However, hearing-related products, features, and services are notoriously heterogeneous and incompatible with other health care systems (no interoperability). Standardization is the process of developing and implementing technical standards (e.g., Noah hearing database). All parties involved in interoperability and standardization realize mutual gains by making mutually consistent decisions. De jure (officially endorsed) standards can be developed in collaboration with large national health care systems as well as spokespeople for hearing care professionals and hearing device users. The roadmap covers mutual collaboration; data privacy, security, and ownership; compliance with current regulations; scalability and modularity; and the scope of interoperability and standards. We propose to join forces to pave the way to the interoperable Internet and audiology products, features, and services that the world needs.

  18. A Single-Lap Joint Adhesive Bonding Optimization Method Using Gradient and Genetic Algorithms

    NASA Technical Reports Server (NTRS)

    Smeltzer, Stanley S., III; Finckenor, Jeffrey L.

    1999-01-01

    A natural process for any engineer, scientist, educator, etc. is to seek the most efficient method for accomplishing a given task. In the case of structural design, an area that has a significant impact on the structural efficiency is joint design. Unless the structure is machined from a solid block of material, the individual components which compose the overall structure must be joined together. The method for joining a structure varies depending on the applied loads, material, assembly and disassembly requirements, service life, environment, etc. Using both metallic and fiber reinforced plastic materials limits the user to two methods or a combination of these methods for joining the components into one structure. The first is mechanical fastening and the second is adhesive bonding. Mechanical fastening is by far the most popular joining technique; however, in terms of structural efficiency, adhesive bonding provides a superior joint since the load is distributed uniformly across the joint. The purpose of this paper is to develop a method for optimizing single-lap joint adhesive bonded structures using both gradient and genetic algorithms and comparing the solution process for each method. The goal of the single-lap joint optimization is to find the most efficient structure that meets the imposed requirements while still remaining as lightweight, economical, and reliable as possible. For the single-lap joint, an optimum joint is determined by minimizing the weight of the overall joint based on constraints from adhesive strengths as well as empirically derived rules. The analytical solution of the sin-le-lap joint is determined using the classical Goland-Reissner technique for case 2 type adhesive joints. Joint weight minimization is achieved using a commercially available routine, Design Optimization Tool (DOT), for the gradient solution while an author developed method is used for the genetic algorithm solution. Results illustrate the critical design variables as a function of adhesive properties and convergences of different joints based on the two optimization methods.

    Radiation scientists represent an important resource in homeland defense. Security analysts worry that a crude but deadly radiological bomb might be fashioned from stolen nuclear material and a few sticks of dynamite. Such a device could kill dozens, hundreds, and possibly thousands and could contaminate a square mile or more. Emergency workers may call upon radiation scientists to aid the injured. Educational materials are available on the ACR, ASTRO, and RRS websites, linked to the Armed Forces Radiobiology Research Institute and the Oak Ridge National Laboratory, to provide radiation workers material that they can use to help emergency room and civil defense personnel after a terrorist attack. Radiation scientists are urged to obtain these materials and contact their local hospital and public health authorities to volunteer their services and expertise.

    2017-12-01

    Nearly a decade ago I was on a team that was exploring a new online network platform for ocean scientists—one of those "Facebook for X" forays that never took off. During the research phase I learned that online groups exhibited a wide range of "stickiness," a description for member engagement. In general, engagement could be plotted on the usual power law curve; a handful of really engaged members on one side, and hundreds or thousands of mostly un-engaged members in the "long-tail" end of the curve.One genre of online groups completely broke this curve. These were the most engaged groups online, and by a long ways. Their entire membership regularly contributed content. The problem was that these groups were made of individuals who had been diagnosed with terminal or incurable chronic physical diseases. Their members sought answers beyond the ken of their individual medical advisors, and they collectively shouldered the news when one of their members inevitably passed on.This leads me back to science (including data science) and to the online engagement of scientists in social networks. From a series of cases and anecdotes collected from other community managers who have attempted to "engage" scientists online, it is clear that science effects its "victims" (scientists) much like an incurable (intellectual) disease. Scientists commonly spend sixty or more hours a week chasing unknowns in their labs, gathering field data, or tracking down software bugs. They share a fever for knowledge and their own common foe: the specific unknown that stands between the state-of-the-science in their specialty and a better understanding of the object of their study; the peculiar intellectual challenge (disease) they have chosen as their quest and their foe.Scientists don't need to join online communities to do science. What scientists need are online collectives that can accelerate their own research, and reward their contributions to new knowledge in their chosen specialty. This talk will detail the difference between science collectives and communities and the activities these can support.

    Hundreds of researchers worldwide have joined forces in the Tara Oceans Expedition to create an unprecedented planetary-scale dataset comprised of state-of-the-art next generation sequencing, microscopy, and physical/chemical metadata to explore ocean biodiversity. This summer the complete collection of data from the 2009-2013 Tara voyage was released. Yet, despite herculean efforts by the Tara Oceans Consortium to make raw data and computationally derived assemblies and gene catalogs available, most researchers are stymied by the sheer volume of the data. Specifically, the most tantalizing research questions lie in understanding the unifying principles that guide the distribution of organisms across the sea and affect climate and ecosystem function. To use the data in this capacity researchers must download, integrate, and analyze more than 7.2 trillion bases of metagenomic data and associated metadata from viruses, bacteria, archaea and small eukaryotes at their own data centers ( 9 TB of raw data). Accessing large-scale data sets in this way impedes scientists' from replicating and building on prior work. To this end, we are developing a data platform called the Ocean Cloud Commons (OCC) as part of the iMicrobe project. The OCC is built using an algorithm we developed to pre-compute massive comparative metagenomic analyses in a Hadoop big data framework. By maintaining data in a cloud commons researchers have access to scalable computation and real-time analytics to promote the integrated and broad use of planetary-scale datasets, such as Tara.

  7. Reflections on science and the governance of alcohol policy.

    Anderson, Peter; Gual, Antoni

    2011-03-01

    To consider, briefly, science's role in informing alcohol policy, and how science could help reframe the present governance of alcohol policy. Expression of the two project coordinators' reflections based on discussions during project meetings of the Alcohol Measures for Public Health Research Alliance (AMPHORA) project. Three endeavours are considered important for science's role in informing alcohol policy: modelling studies that help predict the outcomes of differing policy approaches; studying the impact of live policy changes as a powerful set of natural experiments; and, improved study of the impact of integrated, coordinated and joined up alcohol policies, as opposed to the impact of individual alcohol policy measures. Three areas where science can contribute to strengthened alcohol policy governance include: analysis of different governance architectures that might promote joined-up actions between different sectors; the design of better metrics that measure the impact of public and private sector actions on health; and, by identifying incentives that help consumers make choices on the use of alcohol that improve health. The impact of science on better alcohol policy governance can only happen if there is more and better dialogue between scientists and those who design alcohol policy. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

    Visual evidence ignites curiosity and inspires advocacy. Zoomable imagery and video on a planetary scale provides compelling evidence of human impact on the environment. Earth Timelapse places the observable impact of 30+ years of human activity into the hands of policy makers, scientists, and advocates, with fluidity and speed that supports inquiry and exploration. Zoomability enables compelling narratives and ready apprehension of environmental changes, connecting human-scale evidence to regional and ecosystem-wide trends and changes. Leveraging the power of Google Earth Engine, join us to explore 30+ years of Landset 30m RGB imagery showing glacial retreat, agricultural deforestation, irrigation expansion, and the disappearance of lakes. These narratives are enriched with datasets showing planetary forest gain/loss, annual cycles of agricultural fires, global changes in the health of coral reefs, trends in resource extraction, and of renewable energy development. We demonstrate the intuitive and inquiry-enabling power of these planetary visualizations, and provide instruction on how scientists and advocates can create and share or contribute visualizations of their own research or topics of interest.

    NASA Image and Video Library

    2000-11-20

    ISS01-E-5025 (November 2000) --- This nadir view of Alexandria, Egypt, was provided by a digital still camera image down linked from the International Space Station to flight controllers in Houston. Alexandria (Al Iskandariya) occupies a T-shaped peninsula and strip of land separating the Mediterranean from Lake Mariout. According to NASA scientists studying the Expedition One photo collection, the town was originally built upon a mole (stone breakwater) called Heptastadium, which joined the island of Pharos to the mainland. Since then, the scientists say, sedimentary deposits have added considerably to the width of the mole. Since 1905, when the city’s 370 thousand inhabitants lived in an area of about four square kilometers between the two harbors, the city (population 4 million) has grown beyond its medieval walls and now occupies an area of about 300 square kilometers. The Mahmudiya Canal, connecting Alexandria with the Nile, runs to the south of the city and, by a series of locks, enters the harbor of the principal port of Egypt (note ships). The reddish and ochre polygons west of Lake Mariout are salt-evaporation, chemical-storage, and water-treatment ponds within the coastal lagoon.

    The QuarkNet Collaboration has forged nontraditional relationships among particle physicists, high school teachers and their students. QuarkNet centers are located at 50 + universities and labs across the U.S. and Puerto Rico. We provide professional development for teachers and create opportunities for teachers and students to engage in particle physics data investigations and join research teams. Students develop scientific knowledge and habits of mind by working alongside scientists to make sense of the world using authentic experimental data. Our program is based a classroom vision where teaching strategies emulate closely the way scientists build knowledge through inquiry. We look at how student engagement in research and masterclasses develops an understanding about the process of scientific discovery and science using current scientific data. We also look at ways and to what extent teachers provide scientific discovery and science practices for students and how QuarkNet contributes to the professionalism of participating teachers. Also, we describe success factors that enhance local center programs and describe important benefits of the program that flow to university faculty.

  11. International Polar Year: Science at the Ends of the Earth

    2007-01-01

    In response to unprecedented changes in the fragile polar regions of our planet, the International Polar Year (IPY) 2007-2008 will encompass many scientific studies designed to improve our understanding of polar change and its effects on Earth's ecosystems and people. For 2 years, U.S. Geological Survey (USGS) researchers will don arctic gear and join scientists from more than 60 countries to conduct coordinated research and analysis in the Arctic and Antarctic. Polar regions play a critical role in the global climate system-and changing conditions in these often remote areas greatly affect biological, atmospheric, and human systems around the world. In the 50 years since the last IPY, scientists have seen that Antarctic ice shelves and glaciers worldwide are thinning and retreating, permafrost is thawing, and Arctic sea-ice cover is decreasing. The loss of sea-ice cover adversely affects marine mammal populations and leaves coastal Alaskan villages vulnerable to winter storm erosion. Thawing permafrost threatens the integrity of roads, buildings, and other vulnerable infrastructure and affects the mobility of local populations.

  12. The Rhetoric of Physics: AN Ethnography of the Research and Writing Processes in a Physics Laboratory.

    NASA Astrophysics Data System (ADS)

    Graves, Heather Ann Brodie

    1992-01-01

    This dissertation explores the extent to which rhetoric plays a role in the research and writing processes of physicists. It seeks to join the on-going conversation in the rhetoric of inquiry about the ways in which rhetorical forces shape all knowledge systems. Based on data collected during a six-month ethnography in a thin films laboratory, this study argues that these physicists use rhetoric in all stages of the knowledge creation process. After following the experimental process through all its stages from the inception of an experiment through to publication, this study maps out the types of heuristic devices employed by the physicists as they analyzed, interpreted, and presented their research data in a persuasive scientific article. In light of the insights gained from studying the dynamic interactions between physicists, this dissertation also comments on the theoretical and philosophical debates under discussion in the rhetoric of inquiry and the rhetoric of science. It examines current theories of language (as expressed by rhetoricians, critical theorists, and the physicists in this laboratory) to explore the relationship between reality and language, the role that rhetoric plays in knowledge creation in physics, and the ways in which reality and knowledge may be socially constructed. It concludes that these physicists use rhetorical invention strategies to interpret and present their data. It also argues that scientific knowledge is subject to rhetorical forces because it deals with contingent affairs--phenomena about which scientists advance propositions which appear to be true but about which there is no way to gain absolute certainty or truth. Finally, it concludes that rhetoric both is and is not epistemic in the physics research studied here, and it argues that instead of asking "Is rhetoric epistemic?" perhaps we might shift our attention to inquiring "When is rhetoric epistemic?".

    Environmental science encompasses a wide range of disciplines from water chemistry to microbiology, ecology and atmospheric sciences. Studies often require working across disciplines which differ in their ways of describing and storing data such that it is not possible to devise a monolithic one-size-fits-all data solution. Based on our experiences with Consortium of the Universities for the Advancement of Hydrologic Science Inc. (CUAHSI) Observations Data Model, Berkeley Water Center FLUXNET carbon-climate work and by examining standards like EPA's Water Quality Exchange (WQX), we have developed a flexible data model that allows extensions without need to altering the schema such that scientists can define custom metadata elements to describe their data including observations, analysis methods as well as sensors and geographical features. The data model supports various types of observations including fixed point and moving sensors, bottled samples, rasters from remote sensors and models, and categorical descriptions (e.g. taxonomy) by employing user-defined-types when necessary. It leverages ADO .NET Entity Framework to provide the semantic data models for differing disciplines, while maintaining a common schema below the entity layer. This abstraction layer simplifies data retrieval and manipulation by hiding the logic and complexity of the relational schema from users thus allows programmers and scientists to deal directly with objects such as observations, sensors, watersheds, river reaches, channel cross-sections, laboratory analysis methods and samples as opposed to table joins, columns and rows.

    DOEpatents

    van den Berg, Marcel L.; Batteux, Jan D.; Labov, Simon E.

    2003-01-01

    A heat switch includes two symmetric jaws. Each jaw is comprised of a link connected at a translatable joint to a flexible arm. Each arm rotates about a fixed pivot, and has an articulated end including a thermal contact pad connected to a heat sink. The links are joined together at a translatable main joint. To close the heat switch, a closing solenoid is actuated and forces the main joint to an over-center position. This movement rotates the arms about their pivots, respectively, forces each of them into a stressed configuration, and forces the thermal contact pads towards each other and into compressive contact with a cold finger. The closing solenoid is then deactivated. The heat switch remains closed due to a restoring force generated by the stressed configuration of each arm, until actuation of an opening solenoid returns the main joint to its starting open-switch position.

    Research in recent decades has identified the varied information needs of engineers versus scientists. While most of that research looked at the differences among organizations, we surveyed engineers and scientists within a single Air Force research and development laboratory about their information gathering, usage, and production practices. The results of the Phillips Laboratory survey confirm prior assumptions about distinctions between engineering and science. Because military employees responded at a much higher rate than civilian staff, the survey also became an opportunity to profile a little-known segment of the engineer/scientist population. In addition to the effect Phillips Laboratory's stated mission may have on member engineers and scientists, other factors causing variations in technical communication and information-related activities are identified.

  1. Weld Metallurgy and Mechanical Properties of High Manganese Ultra-high Strength Steel Dissimilar Welds

    NASA Astrophysics Data System (ADS)

    Dahmen, Martin; Lindner, Stefan; Monfort, Damien; Petring, Dirk

    The increasing demand for ultra-high strength steels in vehicle manufacturing leads to the application of new alloys. This poses a challenge on joining especially by fusion welding. A stainless high manganese steel sheet with excellent strength and deformation properties stands in the centre of the development. Similar and dissimilar welds with a metastable austenitic steel and a hot formed martensitic stainless steel were performed. An investigation of the mixing effects on the local microstructure and the hardness delivers the metallurgical features of the welds. Despite of carbon contents above 0.4 wt.% none of the welds have shown cracks. Mechanical properties drawn from tensile tests deliver high breaking forces enabling a high stiffness of the joints. The results show the potential for the application of laser beam welding for joining in assembly of structural parts.

    Harvey Cushing began surgical training with William Halsted at Johns Hopkins in 1896. Cushing joined the Johns Hopkins faculty in 1900 and spent 1 year in Europe in the laboratory of Theodore Kocher. He returned to Johns Hopkins, where he founded neurosurgery as an independent specialty, established the concept of the clinician scientist, discovered the hormonal properties of the pituitary gland and founded endocrinology, introduced intraoperative x-rays into surgical practice, introduced blood pressure monitoring into the operating room, and wrote the first definitive text on neurosurgery. Although there have been many pioneers in our field, Cushing, more than anyone else, developed neurosurgery as a specialty and left a legacy of talented neurosurgeons to develop and expand the field.

    2017-05-01

    Two dissimilar materials, aluminum alloy Al5083-O and advanced high strength steel DP590, were successfully joined by using friction stir spot joining (FSSJ). Satisfactory joint strengths were obtained at a rotational speed of 300 rpm and a plunge depth of 0.7 mm. Resulting joints were welded without a non-welded zone. This may be attributed to the enhanced smooth material flow owing to sufficient stirring effect and tool down force between the upper Al5083-O side and the lower DP590 side. The maximum tensile shear strength was 6.5 kN, which was higher than the joint strength required by the conventional method of resistance spot welding. The main fracture mode was plug fracture in the tensile shear test of joints. An intermetallic compound (IMC) layer with <6 μm thickness was formed at the joint interface, which meets the allowance value of <10 μm for the dissimilar material Al-Fe joints. Thus, the use of FSSJ to weld the dissimilar materials Al5083-O and DP590 resulted in mechanically and metallurgically sound joints.

    A centrifugal combustion synthesis (CCS) process has been investigated to join a Ni-Al intermetallic compound and a Ni-TiC cermet. The cermet, a tubular graphite mold, and a green compact of reactants consisting of Al, Ni and NiO were set in a centrifugal caster. When the combustion synthesis reaction was induced in the centrifugal force field, a synthesized molten Ni-Al alloy flowed into the graphite mold and joined to the cermet. The soundness of the joint interface depended on the volume percentage of TiC phase in the cermet. A lot of defects were formed near the interface between the Ni-TiC cermetmore » and the cast Ni-Al alloy when the volume percentage of TiC was 50% or higher. For this kind of cermet system, using a functionally graded cermet such as Ni-10 vol.%TiC/Ni-25 vol.%TiC/Ni-50 vol.%TiC overcame this difficulty. The four-point bending strength of the joined specimen consisting of the three-layered FGM cermet and cast Ni-29 mol%Al alloy was 1010 MPa which is close to the result for a Ni-29 mol%Al alloy specimen.« less

    The research supported by this project addressed fundamental open physics questions via experiments with subatomic particles. In particular, neutrons constitute an especially ideal “laboratory” for fundamental physics tests, as their sensitivities to the four known forces of nature permit a broad range of tests of the so-called “Standard Model”, our current best physics model for the interactions of subatomic particles. Although the Standard Model has been a triumphant success for physics, it does not provide satisfactory answers to some of the most fundamental open questions in physics, such as: are there additional forces of nature beyond the gravitational, electromagnetic, weakmore » nuclear, and strong nuclear forces?, or why does our universe consist of more matter than anti-matter? This project also contributed significantly to the training of the next generation of scientists, of considerable value to the public. Young scientists, ranging from undergraduate students to graduate students to post-doctoral researchers, made significant contributions to the work carried out under this project.« less
