    This paper describes our work to characterize the variables affecting the smoothed particle hydrodynamics (SPH) method in the LS-DYNA package for simulating high-velocity flyer plate impact experiments. LS-DYNA simulations are compared with one-dimensional experimental data of an oxygen-free high-conductivity (OFHC) copper flyer plate impacting another plate of the same material. The comparison is made by measuring the velocity of a point on the back surface of the impact plate using the velocity interferometer system for any reflector (VISAR) technique.

    Eight one-dimensional plate impact experiments have been performed to study both the Shock to Detonation Transition and Hugoniot state in the cyclotetramethylene tetranitramine (HMX) based explosive EDC32. The experiments covered shock pressures ranging from 0.59 to 7.5 GPa with sustained shocks, double shocks, and short pulse shocks. Experiments were instrumented with embedded magnetic particle velocity gauges. Results include; (1) wave profiles of particle velocity vs. time vs. depth in the explosive, (2) time-distance coordinates for onset of detonation vs. initial shock pressure (aka the Pop-plot), (3) a reactants Hugoniot, and (4) measurement of the Hugoniot Elastic Limit of 0.22.GPa.

    Using gas-gun driven plate impact experiments, we have measured the US - up Hugoniot of the silicone elastomer DC745U cooled to -60 °C. In summary, the initial density changes from p0 (23°C) = 1.312 ± 0.010 g/cm3 to p0 (-60°C) = 1.447 ± 0.011 g/cm3. The linear US - up Hugoniot changes from US = 1.62 + 1.74up km/s at +23°C, to US = 2.03 ± 0.06 + (2.03 ± 0.06) up km/s at -60°C. DC745U, therefore is much stiffer at -60°C than at +23°C, probably due to the crystallization that occurs at ~ -50°C. Caveats/deficiencies: 1) This report does not provide an adequate pedigree of the DC745U used. 2) References to unpublished room temperature shock compression data on the elastomer are inadequate. 3) The report has not been fact checked by a DC745 subject matter expert.

    A series of two-stage gus-gun driven plate impact experiments on PBX 9502 (95 wt.% tri-amino-trinitro-benzene, 5 wt.% Kel-F800 plastic binder) was completed in the 28-34 GPa pressure range. This is just above the Chapman-Jouguet state of ≈ 28 GPa. The experiments consisted of a thick oxygen free high conductivity copper (OFHC Cu) flyer plate impacting a PBX 9502 sample backed by a Lithium Fluoride (LiF) window. Photonic Doppler Velocimetry (PDV) was used to measure velocity histories (wave profiles) at the PBX 9502/LiF interface. Shock transit times and sample thicknesses were converted to shock velocities, Us. Particle velocities, up, were calculated by way of impedance matching. Lastly, the measured wave profiles were compared with numerical simulations of the experiments using the Wescott-Stewart-Davis reactive-burn model.

    HMX (cyclotetramethylene-tetranitramine) based explosive, PBX 9501, is a conventional high explosive formulation composed of 95% wt. of HMX and 5% binders. A series of experiments were performed to investigate one-dimensional combined pressure-shear waves in PBX-9501. This study is thought to be the first to estimate shear stress and strength in a plastic bonded high explosive. Experiments were conducted using Sandia National Laboratories oblique launcher at the Shock Thermodynamics Applied Research (STAR) facility. A projectile is keyed to a slot in the launcher barrel in order to prevent rotation. The projectile is faced with a titanium alloy plate inclined at 20 degrees to the launcher axis. The target consists of a 1 mm thick PBX 9501 disk sandwiched between two titanium alloy plates. Measurements of shear and longitudinal particle velocities were used to determine stresses and infer strength. Longitudinal stresses from 1.4 to 3.1 GPa were applied which presented corresponding shear stresses of 0.1 to 0.23 GPa at high shearing strain rates up to 0.4 x 105s-1. This experimental data now provides for the first time, relevant information for model development.

    Full Text Available Museums all around the globe are starting to adopt advanced technologies that enable the visitors to interact with digital replicas of their collections and artworks. Immersive and interactive virtual reality applications represent one of the most appealing and most used technologies within modern museum exhibitions areas. Using these types of applications the visitors can have access to additional layers of information which can be presented in different languages and presented to the visitor when they demand it using advanced digital interactivity. But the major drawback of these applications is that they don’t allow the users to experience tactile exploration regarding the shapes and ornaments of the cultural heritage artefacts. People are programmed to gather and receive sensory information using their sight, hearing but also using tactile experiences. In order to enable tactile experiences within museum exhibitions, modern technologies such as haptic devices can be installed to enable the visitors to examine the shape of the 3D digital replicas of real artefacts. This paper presents a case study of a haptic device instalment within a museum exhibition that can enable real time tactile exploration of digitized artefacts.

What are the consequences of decided curatorial presentational formats? When does the format work along or even amplify the artwork, and when does it counteract or directly...... destroy the intentions of the artistic gesture? Performance theory provides us with useful tools to read these performative aspects of exhibitions beyond the performance it self. In her aesthetics of the performative, the theatre scholar Erika Fischer-Lichte shows how experimental performances have...... challenged binaries such as aesthetics – politics/ethics, art – life, symbol – signified, body – mind etc. Through this complex play between ‘former binaries’ – that might now exist concurrent or fully collapse – we can rethink categories like work, audience and space once again....

    A new concept of structurally dissipating rock-shed (SDR) was developed by the lab of Tonello IC and LOCIE-ESIGEC (France).To decide the dimension of the plate used in SDR,an ANSYS model which could simulate the impact of rock in the centre of the plate was established by Fabien Delhomme.By using this model,some finite element analyses are carried out in the present paper Firstly,a plate impacted by a block is numerically simulated,the numerical results obtained from different mesh sizes are compared and the accuracy of the finite element model is verified.Then,the dynamic response of the plate impacted at the boundary and in the medium part is computed.By analyzing the stress in rebar,the most dangerous region of impact of plate was found.For a rectangular plate,the most dangerous region is at the corner of the plate when a block drops in.Finally,the whole deformation process of the plate under dropping block was simulated and a simplified definition (effect zone) to describe the deformation process in different positions of plate was given.From this study,it is found that the impact only affects heavily within the effect zone.

  1. Waves in Periodic Dissipative Laminate Metamaterial Generated by Plate Impact

    2015-06-01

    Waves generated by plate impact loading of Al/W laminates with different size of cell were investigated numerically depending on the impactor/cell mass ratio. The materials model took into account viscoplastic behavior of materials. It was observed that this mass ratio has a direct impact on the structure of stress pulses traveling through the composite. At the small impactor/cell mass ratio travelling waves closely resembling solitary waves were quickly formed near the impacted surface. They propagate as quasistationary weakly attenuating localized pulses. The properties of these pulses were satisfactory described based on a theoretical model using dispersive and nonlinear parameters of the materials similar to solitary solutions for the Korteweg-de Vries equation (KdV). The temperature at given pressure at the maximum is dramatically different then the temperature corresponding to the shock wave at the same pressure reflecting a different paths of loading. Increase of impactor/cell mass ratio results in the train of solitary like pulses which number increased with the increase of the impactor/cell mass ratio. At large impactor/cell mass ratio oscillatory stationary shock waves were formed. The leading front of these stationary shock waves was closely described by a solitary like pulse observed at small impactor/cell mass ratio.

    Full Text Available Here is described a research that meant to indentify, through analysis of experiments and contexts in interactive expositions held by centers and museums of science, the necessary conditions for grasping the scientific culture in the post-positivist conception. The project was developed with the participation of students in training courses for teachers on a proposal based on the principles and methods of action research, in order to form skills that lead to interferences in the professional future. The results show that the samples of interactive exhibits are organized according to the classic paradigm: they offer opportunities for experimentation that produce observational data supposedly neutral and maintain separate nature and human being. In conclusion, we have those exhibits contribute to bringing the visitors closer to the positivistic science, not contributing to bring them closer to the concept of science based on the contemporary paradigm of complexity.

  3. Initial stage of flat plate impact onto liquid free surface

    Iafrati, Alessandro; Korobkin, Alexander A.

    2004-07-01

    The liquid flow and the free surface shape during the initial stage of flat plate impact onto liquid half-space are investigated. Method of matched asymptotic expansions is used to derive equations of motion and boundary conditions in the main flow region and in small vicinities of the plate edges. Asymptotic analysis is performed within the ideal and incompressible liquid model. The liquid flow is assumed potential and two dimensional. The ratio of the plate displacement to the plate width plays the role of a small parameter. In the main region the flow is given in the leading order by the pressure-impulse theory. This theory provides the flow field around the plate after a short acoustic stage and predicts unbounded velocity of the liquid at the plate edges. In order to resolve the singular flow caused by the normal impact of a flat plate, the fine pattern of the flow in small vicinities of the plate edges is studied. It is shown that the initial flow close to the plate edges is self-similar in the leading order and is governed by nonlinear boundary-value problem with unknown shape of the free surface. The Kutta conditions are imposed at the plate edges, in order to obtain a nonsingular inner solution. This boundary-value problem is solved numerically by iterations. At each step of iterations the "inner" velocity potential is calculated by the boundary-element method. The asymptotics of the inner solution in both the far field and the jet region are obtained to make the numerical algorithm more efficient. The numerical procedure is carefully verified. Agreement of the computed free surface shape with available experimental data is fairly good. Stability of the numerical solution and its convergence are discussed.

    A new and unique experimental configuration was developed and demonstrated to measure the inhomogeneous deformation of heterogeneous materials during flyer plate impact tests. Flyer plate experiments were performed on a granite material with a small scale structure; strain rates ranged from 105 to 107 s-1. A cross section of an impacted target was monitored and photographed during, and immediately following, passage of the shock wave through the material. Up to fourteen images were taken during passage of the shock wave. This was accomplished using an ultra-high speed Imacon camera with very short exposure times; for example, in one experiment the exposure time was 5 nanoseconds with a framing rate of 5 million frames per second. Continuous wave lasers were used as the illumination source. Edge and notch filters were used to lessen the intensity of the impact flash in the image. The photographic data was analyzed using a digital image correlation (DIC) system. These experiments examined inhomogeneous deformation on a cut plane within an inhomogeneous geological (granite) target.

  15. A pulse-shaping technique to investigate the behaviour of brittle materials subjected to plate-impact tests

    Science.gov (United States)

    Forquin, Pascal; Zinszner, Jean-Luc

    2017-01-01

    Owing to their significant hardness and compressive strengths, ceramic materials are widely employed for use with protective systems subjected to high-velocity impact loadings. Therefore, their mechanical behaviour along with damage mechanisms need to be significantly investigated as a function of loading rates. However, the classical plate-impact testing procedures produce shock loadings in the brittle sample material which cause unrealistic levels of loading rates. Additionally, high-pulsed power techniques and/or functionally graded materials used as flyer plates to smooth the loading pulse remain costly, and are generally difficult to implement. In this study, a shockless plate-impact technique based on the use of either a wavy-machined flyer plate or buffer plate that can be produced by chip-forming is proposed. A series of numerical simulations using an explicit transient dynamic finite-element code have been performed to design and validate the experimental testing configuration. The calculations, conducted in two-dimensional (2D) plane-strain or in 2D axisymmetric modes, prove that the `wavy' contact surface will produce a pulse-shaping effect, whereas the buffer plate will produce a homogenizing effect of the stress field along the transverse direction of the sample. In addition, `wavy-shape' geometries of different sizes provide an easy way to change the level of loading rate and rise time in an experimentally tested ceramic specimen. Finally, when a shockless compression loading method is applied to the sample, a Lagrangian analysis of data is made possible by considering an assemblage of ceramic plates of different thicknesses in the target, so the axial stress-strain response of the brittle sample material can be provided. This article is part of the themed issue 'Experimental testing and modelling of brittle materials at high strain rates'.

    Summer is coming - and with it, a new Microcosm exhibition showcasing CERN (see here). But while the new exhibit is preparing to enchant visitors, many have been asking about the site's former content. Will it simply be out with the old and in with the new? Not as such!   The plasma ball from Microcosm is now on display at the LHCb site. As Microcosm's new content is moving in, its old content is moving up. From LHCb to IdeaSquare, former Microcosm displays and objects are being installed across the CERN site. "Microcosm featured many elements that were well suited to life outside of the exhibition," says Emma Sanders, Microcosm project leader in the EDU group. "We didn't want this popular content to go to waste, and so set out to find them new homes across CERN." The LHCb experiment has received a number of Microcosm favourites, including the Rutherford experiment, the cosmic ray display and the Thomson experiment. "We&...

    2009-12-01

    Presenting the complexity of geosciences to the public via the Internet poses a number of challenges. For example, utilizing various - and sometimes redundant - Web 2.0 tools can quickly devour limited time. Do you tweet? Do you write press releases? Do you create an exhibit or concept map? The presentation will provide participants with a context for utilizing Web 2.0 tools by briefly highlighting methods of online scientific communication across several dimensions. It will address issues of: * breadth and depth (e.g. from narrow topics to well-rounded views), * presentation methods (e.g. from text to multimedia, from momentary to enduring), * sources and audiences (e.g. for experts or for the public, content developed by producers to that developed by users), * content display (e.g. from linear to non-linear, from instructive to entertaining), * barriers to entry (e.g. from an incumbent advantage to neophyte accessible, from amateur to professional), * cost and reach (e.g. from cheap to expensive), and * impact (e.g. the amount learned, from anonymity to brand awareness). Against this backdrop, the presentation will provide an overview of two methods of online information dissemination, exhibits and concept maps, using the WebExhibits online museum (www.webexhibits.org) and SpicyNodes information visualization tool (www.spicynodes.org) as examples, with tips on how geoscientists can use either to communicate their science. Richly interactive online exhibits can serve to engage a large audience, appeal to visitors with multiple learning styles, prompt exploration and discovery, and present a topic’s breadth and depth. WebExhibits, which was among the first online museums, delivers interactive information, virtual experiments, and hands-on activities to the public. While large, multidisciplinary exhibits on topics like “Color Vision and Art” or “Calendars Through the Ages” require teams of scholars, user interface experts, professional writers and editors

  2. Pseudo 5D HN(C)N Experiment to Facilitate the Assignment of Backbone Resonances in Proteins Exhibiting High Backbone Shift Degeneracy

    Kumar, Dinesh; Shukla, Vaibhav Kumar; Pandey, Himanshu; Arora, Ashish; Guleria, Anupam

    2014-01-01

    Assignment of protein backbone resonances is most routinely carried out using triple resonance three dimensional NMR experiments involving amide 1H and 15N resonances. However for intrinsically unstructured proteins, alpha-helical proteins or proteins containing several disordered fragments, the assignment becomes problematic because of high degree of backbone shift degeneracy. In this backdrop, a novel reduced dimensionality (RD) experiment -(5,3)D-hNCO-CANH- is presented to facilitate (and/or to validate) the sequential backbone resonance assignment in such proteins. The proposed 3D NMR experiment makes use of the modulated amide 15N chemical shifts (resulting from the joint sampling along both its indirect dimensions) to resolve the ambiguity involved in connecting the neighboring amide resonances (i.e. HiNi and Hi-1Ni-1) for overlapping amide NH peaks. The experiment -encoding 5D spectral information- leads to a conventional 3D spectrum with significantly reduced spectral crowding and complexity. The impr...

    To complete the revamp of CERN’s Council Chamber, a new exhibition is being installed just in time for the June Council meetings.   Panels will showcase highlights of CERN’s history, using some of the content prepared for the exhibitions marking 50 years of the PS, which were displayed in the main building last November. The previous photo exhibition in the Council Chamber stopped at the 1970s. To avoid the new panels becoming quickly out of date, photos are grouped together around specific infrastructures, rather than following a classic time-line. “We have put the focus on the accelerators – the world-class facilities that CERN has been offering researchers over the years, from the well-known large colliders to the lesser-known smaller facilities,” says Emma Sanders, who worked on the content. The new exhibition will be featured in a future issue of the Bulletin with photos and an interview with Fabienne Marcastel, designer of the exhibit...

    Full Text Available In order to be up–to–date and give visitors a memorable and unique experience, museums are including usage of digital technologies in their exhibitions. Even though museums in Serbia are very important part of tourism offer, they still have traditional settings that are poorly interpreted. The majority of them have a scientific and historical review which is unattractive for various target groups of visitors and for museums it’s important to continually try out new ways in interpretation of their settings. Because technology continues to rapidly change the way we communicate, cultural institutions should adapt to new ways of communication with their visitors. This paper examines mobile technologies that can be used in museums to give visitors a different experience and transfer the knowledge innovatively. In that way it will be presented the modern concept of presentation of museum exhibitions, focusing on usage of mobile devices through mobile applications and QR codes. The paper provides the broad understanding of usage mobile technologies in museum exhibitions with its advantages and limitations. The research results can help the museums management to improve interpretation and communication with visitors and enrich the visitor experience.

    A statistical model of dynamic spall damage due to void nucleation and growth is proposed for ductile materials under intense loading,which takes into account inertia,the elastic-plastic effect,and initial void size.To some extent,void interaction could be accounted for in this approach.Based on this model,the simulation of spall experiments for copper is performed by using the Lagrangian finite element method.The simulation results are in good agreement with experimental data for the free surface velocity profile,stress record behind copper target,final porosity,and void concentrations across the target. The influence of elastic-plastic effect upon the damage evolution is explored.The correlation between the damage evolution and the history of the stress near the spall plane is also analyzed.

The Slovenian cultural heritage is stored on paper or on other media as a part of the library’s Manuscripts, Incunabula and Rare Books Collection, Old Prints Collection, Maps and Pictorial Collection, Music Collection, Ephemera Collection, Serials Collection, and Slovenian Diaspora Publications Collection. Only a small part of the treasures is temporary revealed to the public on special exhibitions. The idea of virtual exhibitions of library treasures was born in 2005. The library aimed to exhibit precious items of special collections of high historical or artistic value. In 2008 the first two virtual exhibitions were created in-house offering access to the rich collections of old postcards of Ljubljana at the beginning of 20th century kept in the Maps and Pictorial Collection of NUK. They were soon followed by other virtual exhibitions. At the beginning they were organised in the same way as physical exhibitions, afterwards different programs were used for creation of special effects (for ex. 3D wall. About two years ago it was decided that the creation of virtual exhibitions will be simplified. Files of digitised and borndigital library materials in jpg format are imported to MS PowerPoint 2010. Each jpg file is now formatted by adding a frame, a description … to the slides which are saved as jpg files.

    The Space Science Institute (SSI) of Boulder, Colorado has recently developed two museum exhibits called Alien Earths and MarsQuest. It has just started to develop another exhibit called Giant Planets. These exhibitions provide research scientists the opportunity to engage in a number of activities that are vital to the success of these major outreach programs. Alien Earths was developed in partnership with various research missions. The focus of the presentation will be on MarsQuest and Giant Planets. MarsQuest is a 5000 square-foot, \\$3M, traveling exhibition that is now touring the country. The exhibit's second 3-year tour will enable millions of Americans to share in the excitement of the scientific exploration of Mars and learn more about their own planet in the process. The associated planetarium show and education program will also be described, with particular emphasis on workshops to orient museum staff (e.g. museum educators and docents) and workshops for master educators near host museums and science centers. The workshops make innovative connections between the exhibition's interactive experiences and lesson plans aligned with the National Science Education Standards. These exhibit programs are good models for actively involving scientists and their discoveries to help improve informal science education in the museum community and for forging a stronger connection between formal and informal education. The presentation will also discuss how Giant Planets, a proposed 3500 square-foot traveling exhibition on the mysteries and discoveries of the outer planets, will be able to take advantage of the connections and resources that have been developed by the MarsQuest project.

This external praise is great encouragement for the CERN exhibitions currently on the drawing board.   The Universe of Particles exhibition has won 4 awards for its avant-garde design. Back in 2008, the design company Atelier Brückner was presented with a challenge: to design the layout of a new permanent exhibition for CERN, one that would epitomize both the Organization and its research. The brief was concise but complex: the exhibit had to be symbolic of the Organization, use modern technology, engage and immerse visitors, and, preferably, use touch-screen technology. With the help of IArt, an interactive technology firm, and based on the content provided by CERN’s Education Group, Atelier Brückner developed the “Universe of Particles” exhibit as it is today.

    The Franklin Institute Science Museum provided an exhibit entitled the Greenhouse Earth: A Traveling Exhibition. This 3500 square-foot exhibit on global climate change was developed in collaboration with the Association of Science-Technology Centers. The exhibit opened at The Franklin Institute on February 14, 1992, welcoming 291,000 visitors over its three-month stay. During its three-year tour, Greenhouse Earth will travel to ten US cities, reaching two million visitors. Greenhouse Earth aims to deepen public understanding of the scientific issues of global warming and the conservation measures that can be taken to slow its effects. The exhibit features hands-on exhibitry, interactive computer programs and videos, a theater production, a demonstration cart,'' guided tours, and lectures. supplemental educational programs at the Institute included a teachers preview, a symposium on climate change, and a satellite field trip.'' The development of Greenhouse Earth included front-end and formative evaluation procedures. Evaluation includes interviews with visitors, prototypes, and summative surveys for participating museums. During its stay in Philadelphia, Greenhouse Earth was covered by the local and national press, with reviews in print and broadcast media. Greenhouse Earth is the first large-scale museum exhibit to address global climate change.

  7. Communicating Complex Sciences by Means of Exhibitions

    Earth Sciences will have to take over the leading role in global sustainable policy and in discussions about climate change. Efforts to raise attention within the politically responsible communities as well as in the public are getting more and more support by executive and advisory boards all over the world. But how can you successfully communicate complex sciences? For example, to start communication about climate change, the first step is to encourage people to be concerned about climate change. After that, one has to start thinking about how to present data and how to include the presented data into an unprejudiced context. Therefore, the communication toolbox offers various methods to reach diverse audiences. The R&D programme GEOTECHNOLOGIEN conducts roving exhibitions as one of its most successful communication tools. With roving exhibitions GEOTECHNOLOGIEN is able to get in touch with different audiences at once. The main purpose and theme of these exhibitions is to convey the everyday means of climate change to the visitors. It is within the responsibility of science to communicate the effects of a phenomenon like climate change as well as the impact of research results to the everyday life of people. Currently, a GEOTECHNOLOGIEN roving exhibition on remote sensing with satellites deals with various issues of environmental research, including a chapter on climate change. By following the 3M-concept (Meaning - Memorable - Moving), exhibitions allow to connect the visitors daily environment and personal experiences with the presented issues and objects. Therefore, hands-on exhibits, exciting multimedia effects and high-tech artefacts have to be combined with interpretive text elements to highlight the daily significance of the scientific topics and the exhibition theme respectively. To create such an exhibition, strong conceptual planning has to be conducted. This includes the specification of stern financial as well as time wise milestones. In addition

    2014-04-01

    The Gravity-Powered Calculator is an exhibit of the Exploratorium in San Francisco. It is presented by its American creators as an amazing device that extracts the square roots of numbers, using only the force of gravity. But if you analyze his concept construction one can not help but recall the research of Galileo on falling bodies, the inclined plane and the projectile motion; exactly what the American creators did not put into prominence with their exhibit. Considering the equipment only for what it does, in my opinion, is very reductive compared to the historical roots of the Galilean mathematical physics contained therein. Moreover, if accurate deductions are contained in the famous study of S. Drake on the Galilean drawings and, in particular on Folio 167 v, the parabolic paths of the ball leaping from its launch pad after descending a slope really actualize Galileo's experiments. The exhibit therefore may be best known as a `Galilean calculator'.

    Full Text Available Appreciation of exhibits in a museum can be equated to a virtual experience of lives in the contexts originally surrounding the exhibits. Here we focus on the importance of weight information, and hence tested whether experiencing a weight during museum exhibit appreciation affects the beholders’ satisfaction and recognition memory for the exhibits. An experiment was performed at a museum exhibiting skeletal preparations of animals. We used nine preparations and prepared four weight stimuli as weight cues in accordance with the actual weight of four of the preparations: Remaining five preparations was displayed without weight stimuli. In the cued condition, participants were asked to lift up the weight stimuli during their observation of the four exhibits. In the uncued condition, participants observed the exhibits without touching the weight stimuli. After observation of the exhibits, the participants responded to a questionnaire that measured their impressions of the exhibits and the museum, and performed a recognition test on the exhibits. Results showed that memory performance was better and viewing duration was longer with weight lifting instruction than without instruction. A factor analysis on the questionnaires revealed four factors (likeability, contentment, value, and quality. A path analysis showed indirect effects of viewing duration on memory performance and willingness-to-pay for the museum appreciation through the impression factors. Our findings provide insight into a new interactive exhibition that enables long appreciation producing positive effects on visitors’ impression, memory, and value estimation for exhibits.

  17. Art Therapy Exhibitions: Exploitation or Advocacy?

    Science.gov (United States)

    2017-01-01

    Promoting awareness of human trafficking by sharing trauma survivors' art and summaries of their life stories suggests ethical complexities that have been typically neglected by bioethicists. Although these survivors voluntarily share the objects they created during art therapy sessions, they are still at risk of harm, including further exploitation, due to their vulnerability, high rates of victim sensitivity, and the mental health consequences of their traumatic experiences. While some argue that the benefits of sublimation and art therapy for human trafficking survivors make sharing their art worth the risk, anti-trafficking organizations and supporters of such art exhibitions have responsibilities to be trauma informed. © 2017 American Medical Association.

  19. Crows spontaneously exhibit analogical reasoning.

    Smirnova, Anna; Zorina, Zoya; Obozova, Tanya; Wasserman, Edward

    2015-01-19

    Analogical reasoning is vital to advanced cognition and behavioral adaptation. Many theorists deem analogical thinking to be uniquely human and to be foundational to categorization, creative problem solving, and scientific discovery. Comparative psychologists have long been interested in the species generality of analogical reasoning, but they initially found it difficult to obtain empirical support for such thinking in nonhuman animals (for pioneering efforts, see [2, 3]). Researchers have since mustered considerable evidence and argument that relational matching-to-sample (RMTS) effectively captures the essence of analogy, in which the relevant logical arguments are presented visually. In RMTS, choice of test pair BB would be correct if the sample pair were AA, whereas choice of test pair EF would be correct if the sample pair were CD. Critically, no items in the correct test pair physically match items in the sample pair, thus demanding that only relational sameness or differentness is available to support accurate choice responding. Initial evidence suggested that only humans and apes can successfully learn RMTS with pairs of sample and test items; however, monkeys have subsequently done so. Here, we report that crows too exhibit relational matching behavior. Even more importantly, crows spontaneously display relational responding without ever having been trained on RMTS; they had only been trained on identity matching-to-sample (IMTS). Such robust and uninstructed relational matching behavior represents the most convincing evidence yet of analogical reasoning in a nonprimate species, as apes alone have spontaneously exhibited RMTS behavior after only IMTS training.

    Transglutaminases are a superfamily of isoenzymes found in cells and plasma. These enzymes catalyze the formation of ε-N-(γ-glutamyl)-lysyl crosslinks between proteins. Cystamine blocks transglutaminase activity and is used in vitro in human samples and in vivo in mice and rats in studies of coagulation, immune dysfunction, and inflammatory disease. These studies have suggested cystamine blocks fibrin crosslinking and has anti-inflammatory effects, implicating transglutaminase activity in the pathogenesis of several diseases. We measured the effects of cystamine on fibrin crosslinking, tissue factor-triggered plasma clot formation and thrombin generation, and coagulation factor enzymatic activity. At concentrations that blocked fibrin crosslinking, cystamine also inhibited plasma clot formation and reduced thrombin generation. Cystamine inhibited the amidolytic activity of coagulation factor XI and thrombin towards chromogenic substrates. These findings demonstrate that cystamine exhibits anticoagulant activity during coagulation. Given the close relationship between coagulation and inflammation, these findings suggest prior studies that used cystamine to implicate transglutaminase activity in disease pathogenesis warrant re-examination.

  5. Mars in their eyes - a cartoon exhibition

    Science.gov (United States)

    Pillinger, Pi.

    Recently a collection of 120 cartoons which tell the story of Mars exploration and scientific discovery, past, present and future, was held in London. We discuss the aims of the exhibition, to what extent we believe the original aims were met and report on additional outreach opportunities resulting from the project. The overriding aim was to capitalise on the popular appeal of accessible art - most people admit to enjoying cartoons. This was strengthened by hanging the originals of cartoons which had, mostly, been published in newspapers and magazines in a wide selection of countries. The provenances served to indicate the attraction of Mars to a wide public. We were fortunate to work with the Cartoon Art Trust of the UK who was in the process of relocating to new premises and opening as The Cartoon Museum, in the tourist area of Bloomsbury, central London, very close to the British Museum. "Mars in their Eyes" ran for 10 weeks during April to July 2006; immediately following which a selection of the cartoons was displayed at the week-long Royal Society Summer Exhibition. We explore the differences between the two exhibitions and comment on the various audience responses. We use this comparison to discuss whether a project which is primarily art can be extended to explain science. Does the coupling merely result in dumbing-down of both cultures or is there a true synergy? The experience has led us to coin the phrase "extreme outreach". Projects which are as ambitious as "Mars in their Eyes", without the security of a safe, captive audience, for example at a Science Centre, must be judged by different criteria. Indeed if the project does not meet comparable targets like large visitor numbers, then the honest evaluation of such details can only inform future activities and must not be reflected in the future funding of only "safe" outreach activities.

  15. Modern museum exhibition technology revolution for audience

    Institute of Scientific and Technical Information of China (English)

    Today's digital revolution leads to the increasing mobile device usage, which has changed people's life and work. However, the traditional static display and graphic version is unable to meet the requirements of the modern audience, which makes museums face the challenge in the distribution of knowledge. Meanwhile, the information storm produced by big data emerged a variety of new media, such as social media, Natural User Interface, Augmented Reality, and electronic publishing. This dizzying array of tools offered opportunities for museums all over the world to become more vibrant and accessible. Museums around the world have been constant changed and improved its presentation, which provides a valuable experience for us. The new Shanghai Natural History Museum has also applied information technology on exhibition, education, research and collection. But the change does not mean a complete subversion. Because the museum audience are di- verse, such as born in a different era, have different learning habits, museums need to control the change magnitude of display technology to meet the requirements of different audience.

  16. Exhibition of Stochastic Resonance in Vestibular Perception

    Astronauts experience sensorimotor changes during spaceflight, particularly during G-transitions. Post flight sensorimotor changes include spatial disorientation, along with postural and gait instability that may degrade operational capabilities of the astronauts and endanger the crew. A sensorimotor countermeasure that mitigates these effects would improve crewmember safety and decrease risk. The goal of this research is to investigate the potential use of stochastic vestibular stimulation (SVS) as a technology to improve sensorimotor function. We hypothesize that low levels of SVS will improve sensorimotor perception through the phenomenon of stochastic resonance (SR), when the response of a nonlinear system to a weak input signal is enhanced by the application of a particular nonzero level of noise. This study aims to advance the development of SVS as a potential countermeasure by 1) demonstrating the exhibition of stochastic resonance in vestibular perception, a vital component of sensorimotor function, 2) investigating the repeatability of SR exhibition, and 3) determining the relative contribution of the semicircular canals (SCC) and otolith (OTO) organs to vestibular perceptual SR. A constant current stimulator was used to deliver bilateral bipolar SVS via electrodes placed on each of the mastoid processes, as previously done. Vestibular perceptual motion recognition thresholds were measured using a 6-degree of freedom MOOG platform and a 150 trial 3-down/1-up staircase procedure. In the first test session, we measured vestibular perceptual thresholds in upright roll-tilt at 0.2 Hz (SCC+OTO) with SVS ranging from 0-700 µA. In a second test session a week later, we re-measured roll-tilt thresholds with 0, optimal (from test session 1), and 1500 µA SVS levels. A subset of these subjects, plus naive subjects, participated in two additional test sessions in which we measured thresholds in supine roll-rotation at 0.2 Hz (SCC) and upright y-translation at 1 Hz

  20. Science Fiction Exhibits as STEM Gateways

    Science.gov (United States)

    Robie, Samantha

    Women continue to hold less than a quarter of all STEM jobs in the United States, prompting many museums to develop programs and exhibits with the express goal of interesting young girls in scientific fields. At the same time, a number of recent museum exhibits have harnessed the popularity of pop culture and science fiction in order to interest general audiences in STEM subject matter, as well as using the exhibits as springboards to expand or shift mission goals and focus. Because science fiction appears to be successful at raising interest in STEM fields, it may be an effective way to garner the interest of young girls in STEM in particular. This research seeks to describe the ways in which museums are currently using science fiction exhibits to interest young girls in STEM fields and careers. Research focused on four institutions across the country hosting three separate exhibits, and included staff interviews and content analysis of exhibit descriptions, promotional materials, a summative evaluation and supplementary exhibit productions. In some ways, science fiction exhibits do serve young girls, primarily through the inclusion of female role models, staff awareness, and prototype testing to ensure interactives are attractive to girls as well as to boys. However, STEM appears to be underutilized, which may be partly due to a concern within the field that the outcome of targeting a specific gender could be construed as "stereotyping".

    Full Text Available The article reflects on temporary exhibitions from a theoretical as well as practical perspective. Regarded as a particularly effective mass-communication medium, exhibitions have a dual nature: they are scholarly undertakings, bringing off a curator’s vision and, simultaneously, they are projects with economic implications that need to be well managed and administered. The role of conservation in the making of temporary exhibitions, either in-house or touring, is here discussed in relation to how work is planned and prioritized as well as how time is managed and staff is allocated. Reference to weaknesses that lessen the crucial input of conservation in the decision-making process is also made. Much of the debate, which focuses on art exhibitions, concerns practicalities encountered in a private museum that extend from the very early stages of selecting objects for display to the mounting of an exhibition.

    How can you make a topic as abstract as black holes seem relevant to the life of the average museum visitor? In 2009, the Harvard-Smithsonian Center for Astrophysics developed a 2500 square foot interactive museum exhibition, "Black Holes: Space Warps & Time Twists,” with funding from the National Science Foundation and NASA. The exhibition has been visited by more than a quarter million museum-goers, and is about to open in its sixth venue at the Reuben H. Fleet Science Center in San Diego, California. We have found that encouraging visitors to adopt a custom black hole explorer's identity can help to make the science of black holes more accessible and meaningful. The Black Holes exhibition uses networked exhibit technology that serves to personalize the visitor experience, to support learning over time including beyond the gallery, and to provide a rich quantitative source of embedded evaluation data. Visitors entering the exhibition create their own bar-coded "Black Holes Explorer's Card” which they use throughout the exhibition to collect and record images, movies, their own predictions and conclusions, and other black hole artifacts. This digital database of personal discoveries grows as visitors navigate through the gallery, and an automated web-content authoring system creates a personalized online journal of their experience that they can access once they get home. We report here on new intriguing results gathered from data generated by 112,000 visitors across five different venues. For example, an initial review of the data reveals correlations between visitors’ black hole explorer identity choices and their engagement with the exhibition. We will also discuss correlations between learning gains and personalization.

    Full Text Available Australian Art history in all it guises has tended to bypass the impact of contemporary curated exhibitions on shaping the discipline. Yet an examination of a cluster of key contemporary exhibitions from the early 1970s onwards reveals their significance for the history of art in Australia. They reflect institutional judgements behind the selection, research and display the work of artists as well as the reception of such work by the public, artists, art critics and art historians. This is especially so in the last decades of the 20th century and the first decade of the 21st, as the country underwent major cultural changes. This paper focuses on selected exhibitions of Australian art from 1968 to 2008 and indicates how exhibitions also constitute a major form of contemporary Australian art historiography. As this period coincides with a transformation in the way exhibitions were funded, it also begins to investigate the question of the long term impact of public funding of the arts.

    The construction and management of exhibition informatization is the main task and choke point during the process of Chinese exhibition industry’s transformation and promotion. There are three key points expected to realize a breakthrough during the construction of Chinese exhibition informatization, and the three aspects respectively are adopting service outsourcing to construct and maintain the database, adopting advanced chest card technology to collect various kinds of information, developing statistics analysis to maintain good cutomer relations. The success of Chinese exhibition informatization mainly calls for mature suppliers who can provide construction and maintenance of database, the proven technology, a sense of data security, advanced chest card technology, the ability of data mining and analysis and the ability to improve the exhibition service basing on the commercial information got from the data analysis. Several data security measures are expected to apply during the process of system developing, including the measures of the terminal data security, the internet data security, the media data security, the storage data security and the application data security. The informatization of this process is based on the chest card designing. At present, there are several types of chest card technology: bar code chest card; two-dimension code card; magnetic stripe chest card; smart-chip chest card. The information got from the exhibition data will help the organizers to make relevant service strategies, quantify the accumulated indexes of the customers, and improve the level of the customer’s satisfaction and loyalty, what’s more, the information can also provide more additional services like the commercial trips, VIP ceremonial reception.

  10. Exhibition Ethics - An Overview of Major Issues

    Directory of Open Access Journals (Sweden)

    Andromache Gazi

    2014-05-01

    Full Text Available Museum ethics are about value judgements. In making such judgements museum personnel is constantly valuing one option over another. This holds true for every aspect of museum work; from collecting policies and conservation to store priorities and exhibition. In recent decades there has been a growing concern in addressing ethical issues in museums as museum workers have developed cultural sensitivity and social responsiveness to a degree unseen before. Most codes of ethics urge museums to give appropriate consideration to represented groups or beliefs. In light of this, it has been recognised that exhibition of sensitive material, for example, must be done with great tact and respect for the feelings of religious, ethnic or other groups represented. Another issue concerns the display of unprovenanced material and repatriation. Yet, these are not the only ethical issues which exhibition developers are faced with. As museum workers we should constantly be reminded that exhibitions are active agents in the construction of knowledge. This paper discusses the hidden assumptions on which museum presentation and interpretation are often based. Decisions about what to include and what to exclude, what is valued and what is not, the means of presentation, language, and so on, all lead to presentational styles which may shape the public’s perception in unintended ways.

During a consultation phase, the communication context was determined, the audience of the project was defined and finally the testing activity-communication effort was determined. We were offered the opportunity to design an exhibition for the local public library. In a consultation phase that corresponded to the design of the exhibition, the stakeholders contributed to its content as well as helping with the funding of the exhibition. Finally, during the experimentation phase, the stakeholders participated in advertising the activity, gathering of participants and designing the scientific survey. In order to assess the effects of the exhibition on risk awareness, several groups of children, teenagers and adults were submitted to a research design, consisting of 1) a pre-test, 2) the visit of the exhibition and 3) a post-test similar to the pre-test. In addition, the children answered a second post-test 3 months after the visit. Close ended questions addressed the awareness indicators mentioned in the literature, i.e. worry level, previous experiences with natural hazards events, exposure to awareness raising, ability to mitigate/respond/prepare, attitude to risk, and demographics. In addition, the post-test included several satisfaction questions concerning the visual tools displayed in the exhibition. A statistical analysis of the changes between the pre- and post- tests (paired t-test, Wilcoxon signed-rank test and bootstrapping) allowed to verify whether the exhibition had an impact on risk awareness or not. In order to deduce which variable

  15. The palaeontological exhibition: a venue for dialogue.

    Understanding the dialogue between museums and their visitors enables museums to subsist, undergo transformations and become consolidated as socially valued cultural venues. The Museo de La Plata (Argentina) was created in the late nineteenth century as a natural history museum, and this study shows that currently the museum is valued socially as a venue for family leisure and education, at which people make sense to the objects exhibited through characteristics conferred upon them by both the institution and the visitor. Nevertheless, such dialogue is somehow affected by the museographic proposal and the public interpretation of the institutional narrative, which could be analysed within the frame of contextual learning. As a consequence, the evolutionary idea that the museum aims to communicate is distorted by the public. This article highlights the importance of considering the visitors' interpretations when planning museum exhibitions, a perspective that has been rather absent in the Argentinian museums.

    The 19-panel exhibition is on display at CERN's Microcosm from Monday to Saturday from 10.00 a.m. to 5.00 p.m.   Marie Curie won the Nobel Prize for Chemistry one hundred years ago. She is the only woman ever to win two Nobel Prizes, which is a testament to her remarkable work. But throughout history, women have played a role in science either in their own right or alongside other scientists. In this special exhibition, the comic-strip artist Fiami takes a look back at the relationship between women and science through his portraits of Mileva Einstein, Marie-Anne Lavoisier and, of course, Marie Curie. Fiami has recently published an entire album devoted to Marie Curie. Texts in French All ages - Entrance free Femmes et Sciences is on display at Microcosm: From Wednesday 21 September 2011 to Tuesday 20 December 2011.

    The Internet is a man-made complex system under constant attacks (e.g., Advanced Persistent Threats and malwares). It is therefore important to understand the phenomena that can be induced by the interaction between cyber attacks and cyber defenses. In this paper, we explore the rich phenomena that can be exhibited when the defender employs active defense to combat cyber attacks. To the best of our knowledge, this is the first study that shows that {\\em active cyber defense dynamics} (or more generally, {\\em cybersecurity dynamics}) can exhibit the bifurcation and chaos phenomena. This has profound implications for cyber security measurement and prediction: (i) it is infeasible (or even impossible) to accurately measure and predict cyber security under certain circumstances; (ii) the defender must manipulate the dynamics to avoid such {\\em unmanageable situations} in real-life defense operations.

    Can the theory of the Big Bang reached by physicists and the concept of creation beloved of religion ever be reconciled? The two approaches have at least one point in common: they do not provide a final answer to the mysteries of the birth of the Universe. And this means that dialogue is alays possible between the two. It is to show the potential of such an exchange that Geneva's Société Evangélique organization is opening an exhibition under the title 'Big Bang and Creation', at the Planète Charmilles shopping centre, to run from 19 to 30 March. View of the 'Big Bang and Creation' exhibition. The exhibition is divided into three sections, showing the views of the scientist and those of the believer without setting them up in opposition to one another.

  4. Synchronization in multicell systems exhibiting dynamic plasticity

    C Suguna; Somdatta Sinha

    2008-08-01

    Collective behaviour in multicell systems arises from exchange of chemicals/signals between cells and may be different from their intrinsic behaviour. These chemicals are products of regulated networks of biochemical pathways that underlie cellular functions, and can exhibit a variety of dynamics arising from the non-linearity of the reaction processes. We have addressed the emergent synchronization properties of a ring of cells, diffusively coupled by the end product of an intracellular model biochemical pathway exhibiting non-robust birhythmic behaviour. The aim is to examine the role of intercellular interaction in stabilizing the non-robust dynamics in the emergent collective behaviour in the ring of cells. We show that, irrespective of the inherent frequencies of individual cells, depending on the coupling strength, the collective behaviour does synchronize to only one type of oscillations above a threshold number of cells. Using two perturbation analyses, we also show that this emergent synchronized dynamical state is fairly robust under external perturbations. Thus, the inherent plasticity in the oscillatory phenotypes in these model cells may get suppressed to exhibit collective dynamics of a single type in a multicell system, but environmental influences can sometimes expose this underlying plasticity in its collective dynamics.

    Connections between Africans and astronomy are the focus of a new exhibition in the National Museum of African Art in Washington, D. C. "African Cosmos: Stellar Arts," which includes artwork, cultural items, and scientific displays from ancient to contemporary times, is the first major exhibit "that brings together arts and science focused on Africa's contribution to keen observations of the heavens over time," curator Christine Mullen Kreamer said at a 20 June news briefing. Among the exhibit's nearly 100 objects are an ancient Egyptian mummy board that includes a representation of the sky goddess Nut, sculptures by the Dogon people of Mali depicting figures in relation to the cosmos, a video that uses data from two square degrees of the Hubble Space Telescope Cosmic Evolution Survey, and a nearly floor-to-ceiling "Rainbow Serpent" constructed of plastic containers by Benin artist Hazoume. An untitled acrylic painting (Figure 1) by South African Gavin Jantjes evokes a myth of the Khoi San people of southern Africa, as it portrays a girl throwing evening fire embers into the night sky, where they remained as the Milky Way.

    This research explores learning in science museums through the most common activity in a science museum—interaction with exhibits. The goal of this study was to characterize the learning behaviors exhibited by students as they engage with interactive exhibits in order to draw insight regarding the design of the exhibits. In order to do so, we used a qualitative method of observation as well as the Visitor Engagement Framework (VEF) model, a visitor-based framework for assessing visitors' learning experiences with exhibits in a science center setting. The combined method produced a framework of nine learning behaviors exhibited during the visitors' interaction with the exhibits, grouped into three categories that reflect increasing levels of engagement and depth of the learning experience. Our research participants consisted of a total 1800 students aged 10-12 (4th, 5th, and 6th graders) who came to the museum with their class for a day visit. We observed nine exhibits, each visited by 200 students. Our observations revealed several design elements that contribute to engagement with exhibits in science museums. For example, exhibits that have familiar activation encourage visitors' interaction, exhibits that facilitate social interaction are more likely to increase engagement, and the highest levels of engagement can be found in exhibits that support large groups.

    Science museums let visitors explore and discover, but for many families there are barriers—such as cost or distance—that prevent them from visiting museums and experiencing hands-on science, technology, engineering, and mathematics (STEM) learning. Now educators are reaching underserved audiences by developing STEM exhibits and programs for public libraries. With more than 16,000 outlets in the United States, public libraries serve almost every community in the country. Nationwide, they receive about 1.5 billion visits per year, and they offer their services for free.

    Full Text Available The article delves into the complex world of exhibition architectures, those whose destiny is reduced to be mounted, exposed and dismantled in a short period of time. A process that allows a quick experience of architecture, bounded in time, and whose experimentation gives rise to the birth of new concepts. The text focuses on the German Pavilion designed by Mies van der Rohe for the Brussels World’s Fair of 1934, his only unbuilt ephemeral architecture due to the political uniqueness of the moment. Now, criticism and the archive allow us to reinterpret its contribution to the history of architecture.

    2015-03-01

    Full Text Available Annual archaeological exhibitions were a visible symbol of archaeological research. Held mainly in London, the displays encapsulated a network of archaeologists, artists, architects and curators, and showcased the work of the first generations of trained archaeologists. The exhibition catalogues and published reviews of the displays provide a unique method for exploring the reception and sponsorship of archaeological work overseas and its promotion to a fascinated, well connected and well moneyed public. The exhibitions were a space in which conversation and networking were as important as educational enrichment. This paper analyses the social history of the “annual exhibition” in archaeology, highlighting the development and maintenance of the networks behind archaeological research, the geography of London as a way to examine influence in archaeology, and the utility of exhibitions for archaeological publicity during this period of exploration.

    Many communities lack good performance facilities for symphonic music, opera, dramatic and musical arts, but have basic convention, exhibition or assembly spaces. It should be possible to develop performance space environments within large multipurpose facilities that will accommodate production and presentation of dramatic arts. Concepts for moderate-cost, temporary enhancements that transform boxy spaces into more intimate, acoustically articulated venues will be presented. Acoustical criteria and design parameters will be discussed in the context of creating a virtual auditorium within the building envelope. Physical, economic, and logistical limitations affect implementation. Sound reinforcement system augmentation can supplement the room conversion. Acceptable control of reflection patterns, reverberation, and to some extent, ambient noise, may be achieved with an array of nonpermanent reflector and absorber elements. These elements can sculpture an enclosure to approach the shape and acoustic characteristics of an auditorium. Plan and section illustrations will be included.

    This paper discusses the potential role of medical museums in public engagement with health and medicine, based in the work of Medical Museion at the University of Copenhagen. Rather than asking if cultural venues such as museums can directly improve the wellbeing of their visitors, we instead...... focus on how museums should communicate about health and medicine. There is increasing emphasis on the need for health communication to recognize peoples’ multiple, lived cultures. We argue that we should also recognize that medical research and practice is itself a form of culture......, and as such is multiple and historically shifting. We suggest that museums are an ideal site for doing so, and can thereby contribute to public engagement with medicine that acknowledges multiplicity on both sides. The paper describes three examples of exhibitions at Medical Museion that attempt to display medicine...

    2015-07-01

    The ketogenic diet (KD) is an established treatment for refractory epilepsy, including some inflammation-induced epileptic encephalopathies. In a lipopolysaccharide (LPS)-induced fever model in rats, we found that animals given the KD for 14 days showed less fever and lower proinflammatory cytokine levels than control animals. However, KD rats exhibited a decrease in circulating levels of arachidonic acid and long-chain n-3 polyunsaturated fatty acids (PUFAs), suggesting that the anti-inflammatory effect of KD was probably not due to an increase in anti-inflammatory n-3 PUFA derivatives. These properties might be of interest in some conditions such as fever-induced refractory epileptic encephalopathy in school-aged children.

    An exhibit of Cassini's images will open at NYC's American Museum of Natural History in March 2008 and then visit the Johnson Art Museum (Cornell) throughout fall 2008, including during next year's DPS. It is under consideration by several other venues in the States and overseas. The exhibit will feature 40-50 images, ranging from letter size to large posters, taken by remote-sensing instruments aboard Cassini and Huygens. Photos will be organized into a half-dozen thematic clusters (e.g., organized by celestial target or by physical process); a panel will introduce each grouping with individual images identified briefly. The Saturn system is a perfect vehicle to educate citizens about planetary science and origins. The images’ beauty should capture the public's attention, allowing us to then engage their curiosity about the relevant science. Among the Saturn system's broad suite of objects are Enceladus and Titan, two satellites of astrobiological interest; moreover, the rings display many processes active in other astrophysical disks. Several auxiliary ideas will be implemented. In Ithaca, we will project images at night against the museum's sand-colored exterior walls. A 10-12 minute musical composition has been commissioned from Roberto Sierra to open the show. We will encourage school children to participate in a human orrery circling the museum and will seek volunteers to participate in several Saturnalia. At Cornell we will involve the university and local communities, by taping their reactions to the images’ exquisite beauty as well as to their scientific content. Cassini will be the E/PO focus of next year's DPS meeting; those materials will be employed throughout the fall at New York schools and be available to travel with the show. We intend to work with NYC partners to offer teacher credits for associated weekend courses. We will produce classroom materials, including a DVD, for teacher use.

    Skin hyper-pigmentation is a condition initiated by the overproduction of melanin existing in the melanocytes. Melanin pigment is responsible for the colour of skin in humans. It is formed through a series of oxidative reactions involving the amino acid tyrosine in the presence of the key enzyme tyrosinase. In continuation with our efforts to identify tyrosinase inhibitors from plants sources, the methanol extract from leaf, bark and fruit of Ceratonia siliqua were screened for tyrosinase inhibition and diphenolase activity. The bark extract exhibited significant inhibition on mushroom tyrosinase using L-tyrosine as a substrate and showed diphenolase activity. The extract further significantly lowered tyrosinase mRNA levels in B16-F10 mouse melanocytes. Bioassay-guided fractionation led to the isolation of six compounds. Compounds (-)-epicatechin-3-O-gallate, 1,2,3,6-tetra-O-galloyl-ß-D-glucose and gallocatechin-3-O-gallate showed tyrosinase inhibitions with the IC50 values of 27.52, 83.30 and 28.30 µg/mL, respectively. These compounds also exhibited L-DOPA activities with IC50 values of >200, 150 and 200 µg/mL, respectively. A clinical study was conducted using 20 volunteers in a patch testing trial for irritancy potential and skin depigmentation. The clinical results showed the sample to be non-irritant with irritancy potential of -34.21 and depigmentation trial showed an improvement in the even skin tone of UV induced pigmentation at 3% after 28 days of application.

    During the last two decades, since digital technologies have become more sophisticated in acquiring real data and building faithful copies of them, their improvements have suggested interesting applications in the field of valorisation of Historical, Cultural and Artistic Heritage, with significant consequences in the share and widespread of knowledge. But although several technologies and methodologies for 3d digitization have recently been developed and improved, the lack of a standard procedure and the costs connected to their use still doesn't encourage the systematic digital acquisition of wide collections and heritage. The aim of this paper is to show the state of the art of a project whose aim is to provide a methodology and a procedure to create digital reproductions of artefacts for Institutions called to preserve, manage and enhance the fruition of archaeological finds inside museums or through digital exhibitions. Our project's aim is to find the most suitable procedure to digitally acquire archaeo logical artefacts that usually have small dimensions and have very complex and detailed surfaces. Within our methodology, particular attention has been paid to the use of widely shared and open-source visualization systems that enhance the involvement of the user by emphasizing three-dimensional characteristics of artefacts through virtual reality.

  1. Rotating pigment cells exhibit an intrinsic chirality.

    Yamanaka, Hiroaki; Kondo, Shigeru

    2015-01-01

    In multicellular organisms, cell properties, such as shape, size and function are important in morphogenesis and physiological functions. Recently, 'cellular chirality' has attracted attention as a cellular property because it can cause asymmetry in the bodies of animals. In recent in vitro studies, the left-right bias of cellular migration and of autonomous arrangement of cells under some specific culture conditions were discovered. However, it is difficult to identify the molecular mechanism underlying their intrinsic chirality because the left-right bias observed to date is subtle or is manifested in the stable orientation of cells. Here, we report that zebrafish (Danio rerio) melanophores exhibit clear cellular chirality by unidirectional counterclockwise rotational movement under isolated conditions without any special settings. The chirality is intrinsic to melanophores because the direction of the cellular rotation was not affected by the type of extracellular matrix. We further found that the cellular rotation was generated as a counter action of the clockwise movement of actin cytoskeleton. It suggested that the mechanism that directs actin cytoskeleton in the clockwise direction is pivotal for determining cellular chirality.

  2. Waves in geomaterials exhibiting negative stiffness behaviour

    Esin, Maxim; Dyskin, Arcady; Pasternak, Elena

    2016-04-01

    Negative stiffness denotes the type of material behaviour when the force applied to the body decreases the body's deformation increases. Some geomaterials, for instance, rocks, demonstrate behaviour of this type at certain loads: during the compression tests the loading curves exhibit descending branch (post-peak softening). One of the possible mechanisms of the negative stiffness appearance in geomaterials is rotation of non-spherical grains. It is important to emphasize that in this case the descending branch may be reversible given that the testing machine is stiff enough (in general case it means an importance of boundary conditions). Existence of geomaterials with a negative modulus associated with rotations may have significant importance. In particular, important is understanding of the wave propagation in such materials. We study the stability of geomaterials with negative stiffness inclusions and wave propagation in it using two approaches: Cosserat continuum and discrete mass-spring models. In both cases we consider the rotational degrees of freedom in addition to the conventional translational ones. We show that despite non positiveness of the energy the materials with negative stiffness elements can be stable if certain conditions are met. In the case of Cosserat continuum the Cosserat shear modulus (the modulus relating the non-symmetrical part of shear stress and internal rotations) is allowed to assume negative values as long as its value does not exceed the value of the standard (positive) shear modulus. In the case of discrete mass-spring systems (with translational and rotational springs) the concentration of negative stiffness springs and the absolute values of negative spring stiffness are limited. The critical concentration when the system loses stability and the amplitude of the oscillations tends to infinity is equal to 1/2 and 3/5 for two- and three-dimensional cases respectively.

    Martial arts are becoming increasingly popular, and many of the techniques used by martial artists can provide effective demonstrations to showcase basic physics concepts. Many students have martial arts experience by the time they reach the senior level of high school or college. In one conceptual physics course, seven students out of 40 had studied some form of martial arts. Teachers can use experienced students as a resource and exploit the popularity of martial arts to demonstrate some basic points in Newtonian mechanics via martial arts demonstrations. This interactive mode of learning, we have found, is very popular and highly motivational for the students. In this paper we provide some of the possible examples of effective classroom demonstrations; there are many additional examples that your students may want to introduce.

    We present a design for Parallax Park, an outdoor, interactive family exhibit for McDonald Observatory that will bring the quest for learning about extra-solar planets and the astronomical distance ladder down to Earth for the more than 100,000 visitors who come to the Observatory each year. The Park will teach visitors the basic principles of astrometry. It will concentrate on distance determination and extrasolar planet detection, and emphasize the advantages of space-based astrometric measurements. Visitors will experience parallax by traveling a path around a representation of the Sun, mimicking Earth's orbit, while viewing representations of stars at various distances and in various directions. Concepts include Cepheids as standard candles, the inverse square law, and motion around a center of mass. The exhibit includes interactive components suitable for children's use. Text labels and printed guides, in English and Spanish, will explain how to use the Park to explore the uses of astrometry in modern science. This program was made possible through funding from the Hubble Space Telescope Cycle 11 and 12 Education and Public Outreach Grant Programs. Support from the NASA/JPL Space Interferometry Mission (JPL contract #1227563) is also gratefully acknowledged.

    To investigate the effect of competitive incentives under peer review, we designed a novel experimental setup called the Art Exhibition Game. We present experimental evidence of how competition introduces both positive and negative effects when creative artifacts are evaluated and selected by peer review. Competition proved to be a double-edged sword: on the one hand, it fosters innovation and product diversity, but on the other hand, it also leads to more unfair reviews and to a lower level of agreement between reviewers. Moreover, an external validation of the quality of peer reviews during the laboratory experiment, based on 23,627 online evaluations on Amazon Mechanical Turk, shows that competition does not significantly increase the level of creativity. Furthermore, the higher rejection rate under competitive conditions does not improve the average quality of published contributions, because more high-quality work is also rejected. Overall, our results could explain why many ground-breaking studies in science end up in lower-tier journals. Differences and similarities between the Art Exhibition Game and scholarly peer review are discussed and the implications for the design of new incentive systems for scientists are explained.

    This Salmon Site Remedial Investigation Report provides the results of activities initiated by the U.S. Department of Energy (DOE) to determine if contamination at the Salmon Site poses a current or future risk to human health and the environment. These results were used to develop and evaluate a range of risk-based remedial alternatives. Located in Lamar County, Mississippi, the Salmon Site was used by the U.S. Atomic Energy Commission (predecessor to the DOE) between 1964 and 1970 for two nuclear and two gas explosions conducted deep underground in a salt dome. The testing resulted in the release of radionuclides into the salt dome. During reentry drilling and other site activities, liquid and solid wastes containing radioactivity were generated resulting in surface soil and groundwater contamination. Most of the waste and contaminated soil and water were disposed of in 1993 during site restoration either in the cavities left by the tests or in an injection well. Other radioactive wastes were transported to the Nevada Test Site for disposal. Nonradioactive wastes were disposed of in pits at the site and capped with clean soil and graded. The preliminary investigation showed residual contamination in the Surface Ground Zero mud pits below the water table. Remedial investigations results concluded the contaminant concentrations detected present no significant risk to existing and/or future land users, if surface institutional controls and subsurface restrictions are maintained. Recent sampling results determined no significant contamination in the surface or shallow subsurface. The test cavity resulting from the experiments is contaminated and cannot be economically remediated with existing technologies. The ecological sampling did not detect biological uptake of contaminants in the plants or animals sampled. Based on the current use of the Salmon Site, the following remedial actions were identified to protect both human health and the environment: (1) the

  11. Development of Exhibit on Arctic Climate Change Called The Arctic: A Friend Acting Strangely Exhibition

    2006-04-01

    The exhibition, The Arctic: A Friend Acting Strangely, was developed at the Smithsonian Institution’s National Museum of Natural History (NMNH) as a part of the museum’s Forces of Change exhibit series on global change. It opened to the public in Spring 2006, in conjunction with another Forces of Change exhibit on the Earth’s atmosphere called Change Is in the Air. The exhibit was a 2000 square-foot presentation that explored the forces and consequences of the changing Arctic as documented by scientists and native residents alike. Native peoples of the Arctic have always lived with year-to-year fluctuations in weather and ice conditions. In recent decades, they have witnessed that the climate has become unpredictable, the land and sea unfamiliar. An elder in Arctic Canada recently described the weather as uggianaqtuq —an Inuit word that can suggest strange, unexpected behavior, sometimes described as that of “a friend acting strangely.” Scientists too have been documenting dramatic changes in the Arctic. Air temperatures have warmed over most—though not all—of the Arctic since the 1950s; Arctic precipitation may have increased by as much as 8%; seasonal melting of the Greenland Ice Sheet has increased on average by 16% since 1979; polar-orbiting satellites have measured a 15¬–20% decline in sea ice extent since the 1970s; aircraft reconnaissance and ship observations show a steady decrease in sea ice since the 1950s. In response to this warming, plant distributions have begun to shift and animals are changing their migration routes. Some of these changes may have beneficial effects while others may bring hardship or have costly implications. And, many scientists consider arctic change to be a ‘bell-weather’ for large-scale changes in other regions of the world. The exhibition included text, photos artifacts, hands-on interactives and other exhibitry that illustrated the changes being documented by indigenous people and scientists alike.

    Full Text Available The New South Wales Migration Heritage Centre was established in 1998. Since 2003 its physical presence has been located within Sydney’s Powerhouse Museum and it has had the strategic brief to record the memories of ageing migrants before their stories are lost. The Centre is, however, a museum without a collection; a heritage authority without heritage sites; a cultural institution whose main presence is in cyberspace. Among its high profile projects is one entitled Objects through time and another Belongings. Both focus on the ways in which objects can convey aspects of the migration experience. Belongings, the focus of this article, presents the remembered experiences of people who migrated to Australia after World War II, and seeks to highlight significant features of their experiences through asking them to share their memories and to nominate and talk about significant objects. As a project it grew out of movable heritage policy work within state government agencies, and its initiators – John Petersen, Kylie Winkworth and Meredith Walker – were central players in this development. It was also inspired by the National Quilt Register of the Pioneer Women’s Hut at Tumbarumba. With its object-centred approach and accompanying edited interview transcripts, Belongings provides a focus for exploring the messages and emphases that emerge when oral history interviews concerned with migration have the specific brief to ask about material culture and its significance. Belongings also enables an exploration of the layering of those messages that emerges when object captions are located back in the context of the oral history interviews from which they were extracted. As a virtual exhibition, Belongings also provides the opportunity to consider the challenges for museums (virtual and real when they need to condense the richness of migrant oral histories and life stories to captioned objects that can be put on display.

    Human Plants, Human Harvest: The Hidden History of California Eugenics is the first-ever exhibition on the history of eugenics in California. The disappearance of this history for half a century, and the consequent absence of a "collective menory", were the primary factors determining the exhibit's sttrcture and content. Responses to the exhibit confirmed that most visitors "never knew" about this history. The exhibit is described in some detail, with selected imagery from the exhibit reproduced. After the initial exhibition, responses of other museums and foundation officials revealed a continuing resistance to this history being publicly displayed, though the sources of resistance varied.

  17. Thermally reduced graphenes exhibiting a close relationship to amorphous carbon

    Graphene is an important material for sensing and energy storage applications. Since the vast majority of sensing and energy storage chemical and electrochemical systems require bulk quantities of graphene, thermally reduced graphene oxide (TRGO) is commonly employed instead of pristine graphene. The sp2 planar structure of TRGO is heavily damaged, consisting of a very short sp2 crystallite size of nanometre length and with areas of sp3 hybridized carbon. Such a structure of TRGO is reminiscent of the key characteristic of the structure of amorphous carbon, which is defined as a material without long-range crystalline order consisting of both sp2 and sp3 hybridized carbons. Herein, we describe the characterization of TRGO, its parent graphite material and carbon black (a form of amorphous carbon) via transmission electron microscopy, Raman spectroscopy, X-ray photoelectron spectroscopy (XPS) and cyclic voltammetry experiments. We used the data obtained as well as consideration of practical factors to perform a comparative assessment of the relative electrochemical performances of TRGO against amorphous carbon. We found out that TRGO and amorphous carbon exhibit almost identical characteristics in terms of density of defects in the sp2 lattice and a similar crystallite size as determined by Raman spectroscopy. These two materials also exhibit similar amounts of oxygen containing groups as determined by XPS and nearly indistinguishable cyclic voltammetric response providing almost identical heterogeneous electron transfer constants. This leads us to conclude that for some sensing and energy storage electrochemical applications, the use of amorphous carbon might be a much more economical solution than the one requiring digestion of highly crystalline graphite with strong oxidants to graphite oxide and then thermally exfoliating it to thermally reduced graphene oxide.

    Krupenye, Christopher; Rosati, Alexandra G; Hare, Brian

    2015-02-01

    Humans exhibit framing effects when making choices, appraising decisions involving losses differently from those involving gains. To directly test for the evolutionary origin of this bias, we examined decision-making in humans' closest living relatives: bonobos (Pan paniscus) and chimpanzees (Pan troglodytes). We presented the largest sample of non-humans to date (n = 40) with a simple task requiring minimal experience. Apes made choices between a 'framed' option that provided preferred food, and an alternative option that provided a constant amount of intermediately preferred food. In the gain condition, apes experienced a positive 'gain' event in which the framed option was initially presented as one piece of food but sometimes was augmented to two. In the loss condition, apes experienced a negative 'loss' event in which they initially saw two pieces but sometimes received only one. Both conditions provided equal pay-offs, but apes chose the framed option more often in the positive 'gain' frame. Moreover, male apes were more susceptible to framing than were females. These results suggest that some human economic biases are shared through common descent with other apes and highlight the importance of comparative work in understanding the origins of individual differences in human choice.

    Mathis, Robert Austin; Sokol, Ethan S; Gupta, Piyush B

    2017-02-01

    Phenotypic heterogeneity in cancers is associated with invasive progression and drug resistance. This heterogeneity arises in part from the ability of cancer cells to switch between phenotypic states, but the dynamics of this cellular plasticity remain poorly understood. Here we apply DNA barcodes to quantify and track phenotypic plasticity across hundreds of clones in a population of cancer cells exhibiting epithelial or mesenchymal differentiation phenotypes. We find that the epithelial-to-mesenchymal cell ratio is highly variable across the different clones in cancer cell populations, but remains stable for many generations within the progeny of any single clone-with a heritability of 0.89. To estimate the effects of combination therapies on phenotypically heterogeneous tumours, we generated quantitative simulations incorporating empirical data from our barcoding experiments. These analyses indicated that combination therapies which alternate between epithelial- and mesenchymal-specific treatments eventually select for clones with increased phenotypic plasticity. However, this selection could be minimized by increasing the frequency of alternation between treatments, identifying designs that may minimize selection for increased phenotypic plasticity. These findings establish new insights into phenotypic plasticity in cancer, and suggest design principles for optimizing the effectiveness of combination therapies for phenotypically heterogeneous tumours.

    2010-02-16

    Ultralyophobic oxidized aluminum surfaces exhibiting negligible contact angle hysteresis for probe liquids were prepared by chemical vapor deposition (CVD) of bis((tridecafluoro-1,1,2,2,-tetrahydrooctyl)-dimethylsiloxy)methylsilane (CF(3)(CF(2))(5)CH(2)CH(2)Si(CH(3))(2)O)(2)SiCH(3)H, (R(F)Si(Me)(2)O)(2)SiMeH). Oxidized aluminum surfaces were prepared by photooxidation/cleaning of sputter-coated aluminum on silicon wafers (Si/Al(Al(2)(O(3)))) using oxygen plasma. X-ray photoelectron spectroscopy (XPS) and atomic force microscopy (AFM) confirmed that this facile CVD method produces a monolayer with a thickness of 1.1 nm on the Si/Al(Al(2)(O(3))) surface without a discernible change in surface morphology. After monolayer deposition, the hydrophilic Si/Al(Al(2)(O(3))) surface became both hydrophobic and oleophobic and exhibited essentially no contact angle hysteresis for water and n-hexadecane (advancing/receding contact angles (theta(A)/theta(R)) = 110 degrees/109 degrees and 52 degrees/50 degrees, respectively). Droplets move very easily on this surface and roll off of slightly tilted surfaces, independently of the contact angle (which is a practical definition of ultralyophobic). A conventional fluoroalkylsilane monolayer was also prepared from 1H,1H,2H,2H-perfluorodecyltrimethoxysilane (CF(3)(CF(2))(7)CH(2)CH(2)Si(OCH(3))(3), R(F)Si(OMe)(3)) for comparison. The theta(A)/theta(R) values for water and n-hexadecane are 121 degrees/106 degrees and 76 degrees/71 degrees, respectively. The larger hysteresis values indicate the "pinning" of probe liquids, even though advancing contact angles are larger than those of the (R(F)Si(Me)(2)O)(2)SiMeH-derived monolayers. The (R(F)Si(Me)(2)O)(2)SiMeH-derived monolayers have excellent hydrolytic stability in water. We propose that the (R(F)Si(Me)(2)O)(2)SiMeH-derived monolayers are flexible and liquidlike and that drops in contact with these surfaces experience very low energy barriers between metastable states, leading to the

  11. Experiencing a constructivist museum exhibit: A case study of twelve children and their families

    Hill, Martha Anne Leech

    2002-04-01

    The American Association for the Advancement of Science and the National Research Council have called for the creation of a scientifically literate populace and introduced science standards and guidelines to direct this process. Science education in traditional school settings plays a key role in reaching this goal, but individuals over their lifetimes will have more exposure to science ideas through informal science experiences such as visits to museums and through diverse media sources. The purpose of this study was to explore the role museums play in this journey to science literacy. This qualitative collective case study examined the experience of 12 children and their families in a children's museum as they interacted with an exhibit designed along the tenets of constructivist theory to introduce children to ideas of science. Twelve children and their families were videotaped interacting with a model of a watershed that included the stream, surrounding land, gravel, and dam building and erosion abatement manipulatives. Children were interviewed to ascertain their stream-related ideas and conceptual understanding prior to and after using the exhibit. Parents completed demographic and post-exhibit experience questionnaires. Two museum staff members who played key roles in the development of the exhibit and surrounding gallery were also interviewed. Individual and cross-case analyses were done to describe the experience of each child and family, and to elucidate the commonalities of these experiences to describe the phenomenon of using a constructivist-based science exhibit. Results of the study indicate (1) the type of experience children and families had at the exhibit depended on child and parent interactions and roles each assumed, and (2) experience with the exhibit encouraged children to think more deeply about water topics, past experiences, and ideas they had previously constructed. Implications of this research include (1) parents should engage children

    Exhibition performance should be evaluated from different perspectives of stakeholders. The benefits of each stakeholder can not be satisfied when evaluating the exhibition performance from a single perspective or. only evaluating the economic performance of the exhibition. In this paper, the stakeholders are defined on the basis of questionnaire investigation and classified by mathematical statistical method. According to the requirements of the stakeholders, the exhibition performance appraisal indicators are extracted and, simplified by factor analysis, which leads to the formation of a set of performance appraisal index system. It is an instructive attempt to work out the exhibition performance appraisal model from the perspective of stakeholders, which may provide theoretical foundation and practice instruction for exhibition performance appraisal in our country.

    Puerto Rico was selected as one of the venues for the exhibit “From Earth to the Solar System” (FETTSS) during the month of October 2011. A set of outreach activities were organized to take place during the month of October aligned with the FETTSS themes. These activities included the following: 1) Main Exhibit, 2) Guided tours for school groups, 3) Planet Festival, 4) Film Festival and 5) Astronomy Conferences. We describe this experience and in particular the work with a group of undergraduate students from the University of Puerto Rico (UPR) that assisted in the outreach events. Among this group were three blind students. The FETTSS exhibit included a set of tactile and Braille images for the blind and visually impaired.

    High- (HA) and low-arched athletes (LA) experience distinct injury patterns. These injuries are the result of the interaction of structure and biomechanics. A suggested mechanism of patellofemoral pain pertains to frontal plane knee moments which may be exaggerated in LA athletes. We hypothesize that LA athletes will exhibit greater peak knee abduction moments than high-arched athletes.

  4. CERN Industrials Exhibitions - Over 30 Years of Tradition

    2001-01-01

    Industrial exhibitions have been part of the CERN landscape for 33 years. At least once each year several companies from the same country come to CERN to present their products and services. Now, a new scheme of one-day visits is giving potential exhibitors at CERN a lighter option. The United Kingdom inaugurated the Industrial Exhibitions in 1968, and it wasn't till 1971 that other countries staged exhibitions at CERN. This photo was taken in 1969, at the second British exhibition, where 16 companies were present. Four years after joining CERN, Poland inaugurated its first exhibition at CERN in 1995 in the presence of the former Director-General Chris Llewellyn-Smith. Almost all the Member States have held industrial exhibitions at the Organization. May '68 wasn't only revolutionary in Paris. For the very first time, an industrial exhibition took place at CERN.

  18. The Black Holes Traveling Exhibition: Visitors Go In, But Does Learning Come Out?

    Dussault, Mary E.; Gould, R.; Sunbury, S.; Londhe, R.

    2011-01-01

    How do you make a fascinating but challenging scientific topic accessible to the broadest audience of museum-goers? What kinds of learning outcomes might escape from a visit to an exhibition on black holes? In 2009, the Harvard-Smithsonian Center for Astrophysics developed a 2500 square foot interactive museum exhibition with funding from the National Science Foundation and NASA. The project pursued two innovations to achieve its educational goals: 1) the participation of youth teams as co-developers of several exhibit and program components; and 2) the use of networked exhibit technology to personalize the visitor experience, to support learning over time including beyond the gallery, and to provide a rich quantitative source of embedded evaluation data. Visitor use a bar-coded "Black Holes Explorer's Card” to gather digital data as they navigate the exhibition, and an automated web-content authorizing system creates a personalized online journal of their experience that they can access once they get home. Summative evaluation results reported by Goodman Research Group include successful implementation of the two project innovations, and multiple positive visitor outcomes in knowledge, engagement and attitudes towards science. Furthermore, the evidence shows that use of the bar-coded Explorer's Card significantly enhances these positive outcomes and that the youth-designed elements contributed to visitor engagement.

    2011-01-01

    Since the 1930s, and with very few exceptions, it has been assumed that the process of radioactive decay is a random process, unaffected by the environment in which the decaying nucleus resides. There have been instances within the past few decades, however, where changes in the chemical environment or physical environment brought about small changes in the decay rates. But even in light of these instances, decaying nuclei that were undisturbed or un-"pressured" were thought to behave in the expected random way, subject to the normal decay probabilities which are specific to each nuclide. Moreover, any "non-random" behavior was assumed automatically to be the fault of the detection systems, the environment surrounding the detectors, or changes in the background radiation to which the detector was exposed. Recently, however, evidence has emerged from a variety of sources, including measurements taken by independent groups at Brookhaven National Laboratory, Physikalisch-Technische Bundesanstalt, and Purdue Univ...

  6. Science, providence, and progress at the Great Exhibition.

    Science.gov (United States)

    Cantor, Geoffrey

    2012-09-01

    The Great Exhibition of 1851 is generally interpreted as a thoroughly secular event that celebrated progress in science, technology, and industry. In contrast to this perception, however, the exhibition was viewed by many contemporaries as a religious event of considerable importance. Although some religious commentators were highly critical of the exhibition and condemned the display of artifacts in the Crystal Palace as giving succor to materialism, others incorporated science and technology into their religious frameworks. Drawing on sermons, tracts, and the religious periodical press, this essay pays close attention to the ways in which science and technology were endowed with providentialist significance and particularly examines the notion of human progress used by a number of Christian writers, especially Congregationalists, who set scientific and technological progress within a teleological religious perspective. This discussion sheds fresh light not only on the Great Exhibition itself but also on the deployment of natural theology in mid-nineteenth-century Britain.

There are no known measurements of sound spillover from such entertainment areas into underwater animal exhibits. Entertainment organizations typically prefer to play music for events at 95 and 100 dBA in a ballroom at Georgia Aquarium. Concern over the potential effects of the music and noise on animals in adjacent exhibits inspired an initial project to monitor and compare sound levels in the adjacent underwater exhibits against the typical in-air sound levels of the ballroom. Measured underwater noise levels were compared to modeled levels based on finite element analysis and plane wave transmission loss calculations through the acrylic viewing window. Results were compared with the model to determine how, if at all, the ambient noise level in the Cold Water Quest exhibit changed as a result of music played in the ballroom.

    The continuing development of exhibits at the Kennedy Space Center's Visitor Complex is an excellent opportunity for NASA personnel to promote science and provide insight into NASA programs and projects for the approximately 3 million visitors that come to KSC annually. Stated goals for the Visitor Complex, in fact, emphasize science awareness and recommend broadening the appeal of the displays and exhibits for all age groups. To this end, this summer project seeks to evaluate the science content of planned exhibits/displays in relation to these developing opportunities and identify specific areas for enhancement of existing or planned exhibits and displays. To help expand the educational and science content within the developing exhibits at the Visitor Complex, this project was structured to implement the goals of the Visitor Center Director. To accomplish this, the exhibits and displays planned for completion within the year underwent review and evaluation for science content and educational direction. Planning emphasis for the individual displays was directed at combining the elements of effective education with fundamental scientific integrity, within an appealing format.

    Young, Denise L.

    The purpose of this study was to examine the exhibition developer role in the context of United States (U.S.) science centers, and more specifically, to investigate the way science center exhibition developers build their professional expertise. This research investigated how successfully practicing exhibition developers described their current practices, how they learned to be exhibition developers, and what factors were the most important to the developers in building their professional expertise. Qualitative data was gathered from 10 currently practicing exhibition developers from three science centers: the Exploratorium, San Francisco, California; the Field Museum, Chicago, Illinois; and the Science Museum of Minnesota, St. Paul, Minnesota. In-depth, semistructured interviews were used to collect the data. The study embraced aspects of the phenomenological tradition and sought to derive a holistic understanding of the position and how expertise was built for it. The data were methodically coded and organized into themes prior to analysis. The data analysis found that the position consisted of numerous and varied activities, but the developers' primary roles were advocating for the visitor, storytelling, and mediating information and ideas. They conducted these activities in the context of a team and relied on an established exhibition planning process to guide their work. Developers described a process of learning exhibition development that was experiential in nature. Learning through daily practice was key, though they also consulted with mentors and relied on visitor studies to gauge the effectiveness of their work. They were adept at integrating prior knowledge gained from many aspects of their lives into their practice. The developers described several internal factors that contributed to their expertise development including the desire to help others, a natural curiosity about the world, a commitment to learning, and the ability to accept critique.

    Cognitive and affective outcomes of a class visit to a participatory science museum were examined by comparing responses of 416 fifth and sixth graders randomly assigned to four conditions (control, exhibit only, lesson only, and exhibit followed by lesson) and two tests (verbal and visual). Students visiting a simple machines exhibit scored higher on a test of science content than the control group, but lower than the group attending a classroom lesson in the museum. The study did not demonstrate conclusively a cognitive advantage of having the exhibit experience prior to the lesson. Scores on the visual test were consistently higher than scores on the verbal test. Study findings indicate that the particular strength of the science museum exhibit lies in the affective domain. Students found the exhibit much more enjoyable, interesting, and motivational than a classroom lesson. Implications of the findings for science education are discussed.

    'Accelerating Science', CERN’s travelling science outreach exhibition, has just arrived at the Middle East Technical University (METU) in Ankara, Turkey for a four-month stay there. This is the first time it has moved outside the circle of the Member States. The Turkish venue will inaugurate some new exhibits that have recently been developed by CERN’s software developers.   “It’s been a very busy day,” says Bilge Demirkoz, an associate professor of physics at METU and a member of AMS-02, who had been overseeing the unloading of the lorries when we spoke to her. “As the University doesn’t have a specific exhibition space, the CERN exhibits are going to be housed in the covered tennis courts just behind the cultural and congress centre. It’s a beautiful venue, and there are plenty of parking spaces.” The University has sent invitations to the exhibition to high schools and to about 100 ...

  4. Arctic Forecasts Available from Polar Bear Exhibit as an Example of Formal/Informal Collaboration

    2012-12-01

    A subset of the general population enjoys and frequents informal education venues, offering an opportunity for lifelong learning that also enhances and supports formal education efforts. The Byrd Polar Research Center (BPRC) at The Ohio State University collaborated with the Columbus Zoo & Aquarium (CZA) in the development of their Polar Frontier exhibit, from its initial planning to the Grand Opening of the exhibit, through the present. Of course, the addition to the Zoo of polar bears and Arctic fox in the Polar Frontier has been very popular, with almost a 7% increase in visitors in 2010 when the exhibit opened. The CZA and BPRC are now investigating ways to increase the climate literacy impact of the exhibit, and to increase engagement with the topics through follow-on activities. For example, individuals or classes anywhere in the world can check forecasts from the Polar Weather and Research Forecasting model and compare them to observed conditions-- allowing deep investigation into changes in the Arctic. In addition, opportunities exist to adapt the Zoo School experience (affecting several Central Ohio school districts) and/or to enable regular participation through social media such as Facebook, Twitter, and other forms of digital communication. BPRC's sustained engagement with the CZA is an example of a trusted and meaningful partnership where open dialogue exists about providing the best learning experience for visitors. This presentation will share some of the lessons learned from this unique partnership, and strategies that are adopted to move it forward.

The research is based on the exhibition visitors’ book, to which a content analysis was applied. The main aim of the paper is to investigate how the ‘Grigore Antipa’ Museum (Romania constructed the cultural context in which the scientific arguments prevailed over the religious ones, turning the exhibition of plastinated human bodies into an accepted public event, with a strong emphasis on education and science (medicine. At the same time, ethical concerns and religious criticism were downplayed by maintaining the focus on the ‘education for health’ frame.

    2013-10-01

    We present a framework, called TrayGen, to generate tray designs for the exhibition and packaging of a collection of objects. Based on principles from shape perception and visual merchandising, we abstract a number of design guidelines on how to organize the objects on the tray for the exhibition of their individual features and mutual relationships. Our framework realizes these guidelines by analyzing geometric shapes of the objects and optimizing their arrangement. We demonstrate that the resultant tray designs not only save space, but also highlight the characteristic of each object and the inter-relations between objects. © 2013 The Eurographics Association and John Wiley & Sons Ltd.

The paper extends the current research of trade shows by analyzing exhibitors ́ motives for exhibiting. The research is conducted for a traditional international agricultural fair - Bread Basket. Exhibitors, including animal production exhibitors, crop production exhibitors and agriculture technology exhibitors, were offered a list of potential motives for exhibiting and were asked to indicate their agreement (disagreement on a 5-point Likert scale. Subsequently, a factor analysis revealed four key factors for exhibiting, including searching for information and company development, product development, focus on company surroundings and new market possibilities. Finally, exhibitors were surveyed again in order to choose one of these factors to be the most important one for exhibiting. Logistic regression revealed how the specific variables (NACE classification, year of establishment and frequency of exhibitin g influence the selected factors.

    Stauffer, B. W.; Fitzhugh, W. W.; Krupnik, I.; Mannes, J.; Rusk, K.

    2003-12-01

    The Arctic: A Friend Acting Strangely is a new exhibit being developed at the Smithsonian Institution's National Museum of Natural History (NMNH) as a part of the museum's Forces of Change exhibit series on global change issues. The exhibit will open to the public in Summer 2004 and is the third component of the series. The other two components are about El Niño (El Niño's Powerful Reach) and atmospheric chemistry (Change is in the Air). The Arctic exhibit's underlying theme is that current global change is causing such rapid shifts in Arctic weather and the polar environment that it has become `strange,' - or unpredictable - to its residents. The speed of change in Arctic ice and climate patterns, ocean and terrestrial ecosystems, and wildlife creates a great challenge for polar scientists; but it also advances beyond the experience and memory of northern indigenous people, who know it so well. The key issues the NMNH team faces in preparing the new exhibit are: how to document and display the forces and consequences of rapid change; how to make complex scientific processes and research comprehensible to visitors; and how to engage the general public in the on-going discussion. Because current shifts in the Arctic environment have been observed and recorded in much detail by scientists and Native residents alike, this topic offers unique opportunities beyond the museum presentation, including outreach through public programs and the Internet. The exhibit is being developed jointly by the NMNH Arctic Studies Center and Office of the Exhibits, and in close collaboration with NOAA' Office of Arctic Research, NSF' new Study of Environmental Arctic Change (SEARCH) initiative, and NASA's Earth Science Enterprise. Exhibit components will include objects, text, graphic panels, video, and a computer interactive. Special efforts will be made to present the voices and opinions of Arctic indigenous people who experience new challenges to their traditional subsistence

The first part of the article conceptualises the notion of the modern curator and surveys the categories of curators. The next part of the article surveys the potential models of curation. There are 7 models of curation distinguished: self- reflexive, “sampling”, traditional, decentralisation curation, virtual curation, art – curator, collaborative – curatorial platform. The third part analyses the activity of a freelance curator in the art exhibition, which is divided into five stages, namely preliminary work, preparation and completion of the organisation plan, realisation, operation, dismantling and evaluation. Each stage is described in great detail specifying what works should be carried out by the curator. The final part of the article analyses the remarks of the curators which are then used to derive the formula of successful curatorship.

    Environmental enrichment (EE) is an integral aspect of modern zoo animal management but, empirical evaluation of it is biased toward species housed in single-species groups. Nocturnal houses, where several nocturnal species are housed together, are particularly overlooked. This study investigated whether three species (nine-banded armadillos, Dasypus novemcinctus; Senegal bush babies, Galago senegalensis; two-toed sloths, Choloepus didactylus) in the nocturnal house at Paignton Zoo Environmental Park, UK could be enriched using food-based and sensory EE. Subjects were an adult male and female of each species. EE was deemed effective if it promoted target species-typical behaviors, behavioral diversity, and increased use of enriched exhibit zones. Results from generalized linear mixed models demonstrated that food-based EE elicited the most positive behavioral effects across species. One set of food-based EEs (Kong®, termite mound and hanging food) presented together was associated with a significant increase in species-typical behaviors, increased behavioral diversity, and increased use of enriched exhibit zones in armadillos and bush babies. Although one type of sensory EE (scented pine cones) increased overall exhibit use in all species, the other (rainforest sounds) was linked to a significant decrease in species-typical behavior in bush babies and sloths. There were no intra or interspecies conflicts over EE, and commensalism occurred between armadillos and bush babies. Our data demonstrate that simple food-based and sensory EE can promote positive behavioral changes in a mixed-species nocturnal mammal exhibit. We suggest that both food and sensory EE presented concurrently will maximize opportunities for naturalistic activity in all species.

    Full Text Available Marcel Duchamp made his first readymade over a century ago: a deceptively simple gesture that would turn the art world upside down. The core of artistic practise no longer lies in creating, but in selecting and displaying. But selecting and displaying are also the core tasks of the independent curator. Duchamp already proved in the 1930’s how powerful an exhibition maker can be. A power struggle arose: who gives meaning to art, the curator or the artist?

    From 12 to 23 June, the Globe of Science and Innovation will be hosting the “Draw me a physicist” exhibition: over 160 drawings and definitions that illustrate how children see the world of research.   In a child’s imagination, scientists are colourful, slightly eccentric figures with unusual powers. This is what emerges from the exhibition on the second floor of the Globe of Science and Innovation, opening on 12 June. “Draw me a physicist” brings together 160 drawings and definitions by children about the profession of research scientist. The exhibition is the result of a six-month project by CERN and 20 primary school classes from the Pays de Gex and the communes of Meyrin, Satigny and Vernier. Some 400 schoolchildren aged 9 to 11 were asked in class to make drawings and come up with definitions of a physicist. Subsequently they came to CERN, visited one of the Laboratory’s sites, and met and interviewed some physicists. They used t...

    Salmonella enterica is a common zoonotic pathogen in humans. Transmission typically occurs through consumption of contaminated food products or contact with infected animals, including poultry or their environment. The objective of this study was to estimate the frequency of Salmonella contamination in the environment in poultry exhibits at agricultural fairs. Samples were collected from cages, feed, floors and tables in the exhibit and cultured for Salmonella. At least one environmental sample was positive for Salmonella in 10 of 11 fairs (91%), and Salmonella was isolated from 28 of 55 environmental samples (50.9%). Eleven different serotypes were detected. Results of this study demonstrate that environmental surfaces at agricultural fairs can be contaminated with Salmonella and could potentially serve as a route of transmission to bird owners and the general public. Poultry owners and the general public should be educated about the risks of Salmonella infection from the poultry exhibit environment. Agricultural fairs should consider instituting policies and practices to improve hygiene and mitigate the risk of zoonotic salmonellosis.

    Stigma reduction efforts in Vietnam have been encumbered by contradictory and dynamic views of people living with HIV and the epidemic over the past two decades. World AIDS Day 2010 saw the launch of Pain and Hope, a museum exhibition showcasing the lives and experiences of Vietnamese people living with AIDS at the Vietnam Museum of Ethnology (VME). Between December 2010 and May 2011, a random sample of visitors completed exit surveys regarding their attitudes towards the exhibition and Vietnamese living with HIV/AIDS. The survey sought to determine what kind of visitors the museum and exhibition attracted, and the stigma-related impacts of this kind of exposure and parasocial contact. Of 2500 Vietnamese visitors randomly selected, 852 completed the computer surveys (response rate of 34.1%), 92.3% of whom had seen Pain and Hope. We found two sub-strata or types of visitors attending the exhibition, with varying demographic characteristics, HIV-related knowledge, some differences in stigma ideation, and clear differences in intended behaviours specifically attributable to the exhibition. Social desirability biases notwithstanding, there has emerged a diptych typology of visitors to the VME, for whom the experience of the exhibition is likely interacting with divergent prior knowledge, experiences, interests and motivations.

  15. Stable functional networks exhibit consistent timing in the human brain.

    Despite many advances in the study of large-scale human functional networks, the question of timing, stability, and direction of communication between cortical regions has not been fully addressed. At the cellular level, neuronal communication occurs through axons and dendrites, and the time required for such communication is well defined and preserved. At larger spatial scales, however, the relationship between timing, direction, and communication between brain regions is less clear. Here, we use a measure of effective connectivity to identify connections between brain regions that exhibit communication with consistent timing. We hypothesized that if two brain regions are communicating, then knowledge of the activity in one region should allow an external observer to better predict activity in the other region, and that such communication involves a consistent time delay. We examine this question using intracranial electroencephalography captured from nine human participants with medically refractory epilepsy. We use a coupling measure based on time-lagged mutual information to identify effective connections between brain regions that exhibit a statistically significant increase in average mutual information at a consistent time delay. These identified connections result in sparse, directed functional networks that are stable over minutes, hours, and days. Notably, the time delays associated with these connections are also highly preserved over multiple time scales. We characterize the anatomic locations of these connections, and find that the propagation of activity exhibits a preferred posterior to anterior temporal lobe direction, consistent across participants. Moreover, networks constructed from connections that reliably exhibit consistent timing between anatomic regions demonstrate features of a small-world architecture, with many reliable connections between anatomically neighbouring regions and few long range connections. Together, our results demonstrate

  16. Lessons from life: Learning from exhibits, animals and interaction in a museum

    Goldowsky, Alexander Noah

    This study examines the effect of interaction on visitor behavior at a public aquarium, experimentally comparing one exhibit under interactive and noninteractive conditions. A quantitative analysis showed that the time visitor groups spent in the study area significantly increased in the interactive condition (median 73 vs. 32 seconds). Further, this effect extended only to those groups within the interactive condition in which at least one member operated the exhibit (median 102 vs. 36 seconds). Both median times and survival curves are compared, and the analysis controlled for group size, age and sex ratios, visitor density, queuing time, and animal activity. Qualitative analyses focused on visitors' spontaneous conversation at the exhibit. Interactive visitors were found to engage in more in-depth exploration, including conducting informal experiments. The amount of discussion was found to correlate with stay time (r = 0.47). Visitor discussion centered on the exhibit, with frequent observations of penguin behavior. Greater enthusiasm was observed for interactive visitors, and coding showed interactive visitors laughed more frequently, and were significantly more likely to speculate on the penguins' reactions and motivations for behaviors. The experimental setup included a control condition consisting of a typical aquarium exhibit, including live penguins, naturalistic habitat, and graphics. The interactive condition added a device designed to mediate a two-way interaction between the visitors and penguins: visitors moved a light beam across the bottom of the pool. The penguins, intern, chased the light. This exhibit was designed both to benefit visitors and to serve as behavioral enrichment for the penguins. A third condition employed an automatically moving light, which elicited similar penguin behaviors, but without allowing visitor interaction. Videotaped data was analyzed for 301 visitor groups (756 individuals). A supplemental study employed video recall

    Based on the theory of transformation optics, a type of homogeneous illusion device exhibiting transformed and shifted scattering effect is proposed in this paper. The constitutive parameters of the proposed device are derived, and full-wave simulations are performed to validate the electromagnetic properties of transformed and shifted scattering effect. The simulation results show that the proposed device not only can visually shift the image of target in two dimensions, but also can visually transform the shape of target. It is expected that such homogeneous illusion device could possess potential applications in military camouflage and other field of electromagnetic engineering.

    Prostacyclin analogues are standard therapeutic options for vasoconstrictive diseases, including pulmonary hypertension and Raynaud's phenomenon. Although effective, these treatment strategies are expensive and have several side effects. To improve drug efficiency, we tested liposomal nanoparticles as carrier systems. In this study, we synthesized liposomal nanoparticles tailored for the prostacyclin analogue iloprost and evaluated their pharmacologic efficacy on mouse intrapulmonary arteries, using a wire myograph. The use of cationic lipids, stearylamine, or 1,2-di-(9Z-octadecenoyl)-3-trimethylammonium-propane (DOTAP) in liposomes promoted iloprost encapsulation to at least 50%. The addition of cholesterol modestly reduced iloprost encapsulation. The liposomal nanoparticle formulations were tested for toxicity and pharmacologic efficacy in vivo and ex vivo, respectively. The liposomes did not affect the viability of human pulmonary artery smooth muscle cells. Compared with an equivalent concentration of free iloprost, four out of the six polymer-coated liposomal formulations exhibited significantly enhanced vasodilation of mouse pulmonary arteries. Iloprost that was encapsulated in liposomes containing the polymer polyethylene glycol exhibited concentration-dependent relaxation of arteries. Strikingly, half the concentration of iloprost in liposomes elicited similar pharmacologic efficacy as nonencapsulated iloprost. Cationic liposomes can encapsulate iloprost with high efficacy and can serve as potential iloprost carriers to improve its therapeutic efficacy.

    When the Council Chamber was renovated, the old photographs displayed on the walls were taken down... they've now been replaced by new panels printed on Plexiglas. The theme of the exhibition is still the history of CERN, but it now features the very latest from graphic design. Fabienne Marcastel, who designed it, tells us more. Two of the new panels recently installed in the Council Chamber. The presentation is simple and elegant. The content is based essentially on the accelerators and the aim of the graphic design is not to attract the public's attention to the panels but rather to provide a pleasant décor for the Chamber's users. "The old photographs stopped at the LEP. The new panels show the history of CERN but also what the Laboratory is like today. Visually, the plan is the starting point, the key to understanding how CERN has changed. It shows how CERN occupies the land it is built on," explains Fabienne Marcastel, the exhibition's graphic designer. The four panels a...

  5. Chimpanzees and bonobos exhibit emotional responses to decision outcomes.

    Directory of Open Access Journals (Sweden)

    Alexandra G Rosati

    Full Text Available The interface between cognition, emotion, and motivation is thought to be of central importance in understanding complex cognitive functions such as decision-making and executive control in humans. Although nonhuman apes have complex repertoires of emotional expression, little is known about the role of affective processes in ape decision-making. To illuminate the evolutionary origins of human-like patterns of choice, we investigated decision-making in humans' closest phylogenetic relatives, chimpanzees (Pan troglodytes and bonobos (Pan paniscus. In two studies, we examined these species' temporal and risk preferences, and assessed whether apes show emotional and motivational responses in decision-making contexts. We find that (1 chimpanzees are more patient and more risk-prone than are bonobos, (2 both species exhibit affective and motivational responses following the outcomes of their decisions, and (3 some emotional and motivational responses map onto species-level and individual-differences in decision-making. These results indicate that apes do exhibit emotional responses to decision-making, like humans. We explore the hypothesis that affective and motivational biases may underlie the psychological mechanisms supporting value-based preferences in these species.

    Increased bone water content resulting from repetitive patellofemoral joint overloading has been suggested to be a possible mechanism underlying patellofemoral pain (PFP). To date, it remains unknown whether persons with PFP exhibit elevated bone water content. The purpose of this study was to determine whether recreational runners with PFP exhibit elevated patella water content when compared to pain-free controls. Ten female recreational runners with a diagnosis of PFP (22 to 39years of age) and 10 gender, age, weight, height, and activity matched controls underwent chemical-shift-encoded water-fat magnetic resonance imaging (MRI) to quantify patella water content (i.e., water-signal fraction). Differences in bone water content of the total patella, lateral aspect of the patella, and medial aspect of the patella were compared between groups using independent t tests. Compared with the control group, the PFP group demonstrated significantly greater total patella bone water content (15.4±3.5% vs. 10.3±2.1%; P=0.001), lateral patella water content (17.2±4.2% vs. 11.5±2.5%; P=0.002), and medial patella water content (13.2±2.7% vs. 8.4±2.3%; Ppatella water content observed in female runners with PFP is suggestive of venous engorgement and elevated extracellular fluid. In turn, this may lead to an increase in intraosseous pressure and pain. Copyright © 2014 Elsevier Inc. All rights reserved.

    Chitinases are necessary for fungal cell wall remodeling and cell replication. Methylxanthines have been shown to competitively inhibit family 18 chitinases in vitro. We sought to determine the effects of methylxanthines on fungal chitinases. Fungi demonstrated variable chitinase activity and incubation with methylxanthines (0.5–10 mM) resulted in a dose-dependent decrease in this activity. All fungi tested, except for Candida spp., demonstrated growth inhibition in the presence of methylxanthines at a concentration of 10 mM. India ink staining demonstrated impaired budding and decreased cell size for methylxanthine-treated Cryptococcus neoformans. C. neoformans and Aspergillus fumigatus treated with pentoxifylline also exhibited abnormal cell morphology. In addition, pentoxifylline-treated C. neoformans exhibited increased susceptibility to calcofluor and a leaky melanin phenotype consistent with defective cell wall function. Our data suggest that a variety of fungi express chitinases and that methylxanthines have antifungal properties related to their inhibition of fungal chitinases. Our results highlight the potential utility of targeting chitinases in the development of novel antifungal therapies. PMID:21968902

    Full Text Available Maternal smoking during pregnancy is associated with increased substance abuse in offspring. Preclinical research shows that in utero exposure to nicotine, the primary psychoactive compound in tobacco smoke, influences the neurodevelopment of reward systems and alters motivated behavior in offspring. The present study determined if prenatal nicotine (PN exposure altered the sensitivity to the reinforcing and aversive effects of methamphetamine (METH in offspring using a low dose, intravenous (IV exposure method. Pregnant dams were administered nicotine (0.05 mg/kg/injection or prenatal saline (PS 3×/day on gestational days 8-21, and adult offspring were tested using METH self-administration (experiment 1 or METH-induced conditioned taste aversion (CTA; experiment 2 procedures. For METH self-administration, animals were trained to respond for IV METH (0.05 mg/kg/injection; fixed-ratio 3 and they were tested on varying doses the reinforcer (0.0005-1.0 mg/kg/injection. For METH CTA, rats received three saccharin and METH pairings (0, 0.3, or 0.5 mg/kg, sc followed by fourteen daily extinction trials. Experiment 1: PN and PS animals exhibited inverted U-shaped dose-response curves; however, the PN animal’s curve was shifted to the left, suggesting PN animals were more sensitive to the reinforcing effects of METH. Experiment 2: METH CTA was acquired in a dose-dependent manner and the factor of PN exposure was not related to the acquisition or extinction of METH-induced CTA. There were no sex differences in either experiment. These results indicate that adult offspring of IV PN exposure exhibited altered motivation for the reinforcing effects of METH. This suggests that PN exposure, via maternal smoking, will alter the reinforcing effects of METH during later stages of development, and furthermore, will influence substance use vulnerability in adult human offspring.

    Artists such as myself can influence the public discourse on climate change through compelling imagery transcending data and language. I will speak specifically to how I communicate scientific research to diverse populations by making those issues personal, visceral, and actionable.I began integrating scientific visual data into my aesthetic practice ten years ago by first utilizing archival evidence in the form of repeats, geological charts of recessional lines, graphs, symbols and Landsat maps. I continue to develop visual strategies delivering information on an emotional/non-verbal level. In the past 4 years, I have added the most dramatic layer to my creative process: bearing witness. I've been to the three largest ice fields in the world: Greenland, Antarctica and Argentina's Patagonia, observing the unprecedented pace of glacial melt. The emotional significance of actually being there as an artist is immense. Those expeditions impact my practice, leading to exhibitions that open a dialog with an audience not initially interested in science. In the past 5 years my work has appeared in 6 solo and 19 group exhibits all devoted to the environment. I make myself present in universities, museums and galleries to explain what the images are about. I require universities to include a public component: an all-college lecture or panel where the geography/environmental/sociology/geology departments participate with broad student involvement. I believe that such endeavors are worthwhile and can be models for further efforts to educate an unsuspecting audience. Artists can bridge the gap communicating to a public of art appreciators, nonscientists - how easy it is to understand geology and global warming. This social engagement can even inspire and result in attitudinal changes. A viewer's initial emotional response to my large paintings and photographs evolves into comprehension as a dialog about their content is revealed. By sharing my personal story about my

The approach considers a finite slab of meta material consisting of axis-symmetric designable unit...... cells subjected to an exterior field. The unit cell is designed to achieve the desired properties based on tailoring the response of the meta material slab underthe exterior field. The approach is directly applicable to physical problems modeled by the Helmholtz equation, such as acoustic, elastic...... and electromagnetic wave problems. Acoustic meta materials with unit cell size on the order of half the wave length are considered as examples. Optimized designs are presented and their performance under varying frequency and angle of incidence is investigated....

    The study investigates the effects of aqueous extract of Bougainvillea spectabilis leaves on blood glucose, glycosylated hemoglobin, lipid profile, oxidative stress, and on DNA damage, if any, as well as on liver and kidney functions in streptozotocin-induced diabetes in Wistar rats. Daily administration of the aqueous extract of B spectabilis leaves for 28 days resulted in significant reduction in hyperglycemia and hyperlipidemia as evident from restoration of relevant biochemical markers following extract administration. The extract also exhibited significant antioxidant activity as evidenced from the enzymatic and nonenzymatic responses and DNA damage markers. The extract restored kidney and liver functions to normal and proved to be nontoxic. A marked improvement in the histological changes of tissues was also observed. The present study documented antihyperglycemic, antihyperlipidemic, and antioxidative potentials of the aqueous extract of B spectabilis leaves without any toxicity in streptozotocin-treated Wistar rats.

    2002-01-01

    Infrared radiant powder was synthesized by conventional ceramic processing techniques by using Fe2O3, MnO2, CuO, Co2O3 and kaolin as raw materials. A novel infrared radiant glaze was developed by introducing the infrared radiant powder into glazing as a functional additive. Infrared radiant characteristics of the powder and the glaze were investigated. The optimum content of infrared radiant powder in glazing was ascertained to be 5%. The infrared radiant glaze exhibits significant antibacterial and antifungal functions due to the thermal effect of infrared radiation. Antibacterial percentages of the glaze reach 91%-100% when Escherichia coli, Staphylococcus aureus and Bacillus subtilis are used as model bacterium respectively, while antifungal percentage of the glaze exceeds 95% when Penicillum citrinum is used as model fungus.

Although effective, these treatment strategies are expensive and have several side effects. To improve drug efficiency, we tested liposomal nanoparticles as carrier systems. In this study, we synthesized liposomal nanoparticles tailored for the prostacyclin analogue iloprost and evaluated their pharmacologic efficacy on mouse intrapulmonary arteries, using a wire myograph. The use of cationic lipids, stearylamine, or 1,2-di-(9Z-octadecenoyl-3-trimethylammonium-propane (DOTAP in liposomes promoted iloprost encapsulation to at least 50%. The addition of cholesterol modestly reduced iloprost encapsulation. The liposomal nanoparticle formulations were tested for toxicity and pharmacologic efficacy in vivo and ex vivo, respectively. The liposomes did not affect the viability of human pulmonary artery smooth muscle cells. Compared with an equivalent concentration of free iloprost, four out of the six polymer-coated liposomal formulations exhibited significantly enhanced vasodilation of mouse pulmonary arteries. Iloprost that was encapsulated in liposomes containing the polymer polyethylene glycol exhibited concentration-dependent relaxation of arteries. Strikingly, half the concentration of iloprost in liposomes elicited

    Subject specialty libraries like the Earth Sciences and Map Library at UC Berkeley thrive on active user communities, but promoting awareness of resources and services can be slow and time-consuming. In Fall 2014, two new librarians there introduced a series of monthly pop-up exhibits called "Maps and More" in order to help build that community. Now in their third year, the show-and-tell sessions are designed to lure visitors into the library and spark new connections among students, researchers and librarians, and renewed engagement with library collections. The librarians surveyed participants in spring 2015 and fall 2016 to assess the impact of "Maps and More" in terms of visitors' perception of the events and awareness of library services and materials. One significant finding from the spring 2015 survey is that a quarter of respondents had never been to the Earth Sciences and Map Library before the session. The exhibits draw in participants from a range of departments, including significant numbers from Seismology, Earth and Planetary Science, Geography, as well as members of the public. Sessions held on Cal Day - the university's annual public open house with 30-40,000 public visitors - were particularly good outreach experiences. Partnerships with other units have great potential for expanding the reach of these events. The Maps and More exhibits have proven to be a successful outreach tool for raising the profile of the library collections and services and helping users understand maps as research materials.

  3. Acceptance and Conformity Merging Modernity with Nationalism in the Stockholm Exhibition in 1930

    2010-12-01

    Full Text Available This article takes a closer look at how interwar supporters of modernism sought to overcome the opposition they had to face. It does so by looking at the usage of history and Swedishness at the Stockholm Exhibition in 1930 and contrasting this experience with a brief excursus on the image of progress and Americanism as presented at the A Century of Progress International Exposition, held in Chicago in 1933–1934. The backers of both these exhibitions – functionalist architects and progressive businessmen, respectively – consciously sought to find ways in which to savor the propagandistic value of this “the shock of the new” while retaining a reassuring continuity between well-known and widespread self-identifications with “the idyll of the past.” They did so by forging “national” forms of modernity, attempting to bypass the political conflicts and ideological polarizations which characterized the interwar years. As such, it is argued, they also exemplify how the logic of the exhibition could be used for harnessing technology, science, and funkis (functionalism as tools for re-identifying the nation with modernity and simultaneously de-politicizing modernism.

    High-energy Heavy Ion Physics studies strongly interacting matter at extreme energy densities.QCD predicts that at such densities hadronic matter turns into a plasma of deconfined quarks and gluons,the Quark Gluon Plasma (QGP).Matter in the Universe must have existed in this state up to about 10 ms after the Big Bang.Today QGP might exist in the c re of neutron stars.The study of the phase diagram of matter is a new approach to investigate QCD at its natural scale,L QCD ,and to address the fundamental questions of confinement and chiral-symmetry breaking.The combined results obtained by the SPS heavy ion experiments,in particular those obtained with the Pb beam,pr vide compelling evidence for the existence of a new state of matter featuring many of the characteristics predicted for the QGP.The ALICE experiment will carry this research into the LHC era.

    L3 aimed to specialize in measuring electrons, positrons, and photons emerging at small angles to LEP's colliding beams with the best possible precision. To achieve this, special crystals made from Bismuth Germanate, BGO, were chosen. Such crystals had previously only been made in small quantities, a few cubic centimetres, and never with the purity required by L3. The experiment would need a massive 12 tons of BGO crystals.

    Increasing ocean temperatures and strengthening boundary currents have caused the poleward migration of many marine species. Cubozoan jellyfish known to cause Irukandji syndrome have historically been confined to tropical waters but may be expanding into subtropical regions. Here, we examine the interactive effects of warming and acidification on the population dynamics of polyps of an Irukandji jellyfish, Alatina nr mordens, and the formation of statoliths in newly metamorphosed medusae, to determine if this jellyfish could tolerate future conditions predicted for southeast Queensland (SEQ), Australia. Two experiments, examining the orthogonal factors of temperature and pH, were undertaken. Experiment 1 mimicked the current, ca. 2050 and ca. 2100 summer temperature and pH conditions predicted for SEQ using A1F1 scenarios (temperature: 25, 27, 29 °C; pH: 7.9, 7.8, 7.6) and Experiment 2 mimicked current and future winter conditions (18 and 22 °C, pH 7.9, 7.8, 7.6). All polyps in Experiment 1 survived and budded. Fewer polyps budded in the lower pH treatments; however, patterns varied slightly among temperature treatments. Statoliths at pH 7.6 were 24% narrower than those at pH 7.8 and 7.9. Most polyps survived the winter conditions mimicked by Experiment 2 but only polyps in the 22 °C, pH 7.9 treatment increased significantly. The current absence of A. nr mordens medusae in SEQ, despite the polyps' ability to tolerate the current temperature and pH conditions, suggests that ecological, rather than abiotic factors currently limit their distribution. Observations that budding was lower under low pH treatments suggest that rates of asexual reproduction will likely be much slower in the future. We consider that A. nr mordens polyps are likely to tolerate future conditions but are unlikely to thrive in the long term. However, if polyps can overcome potential ecological boundaries and acidification proceeds slowly A. nr mordens could expand polewards in the short

    Creating a natural disaster-ready community requires interoperating scientific, technical, and social systems. In addition to the technical elements that need to be in place, communities and individuals need to be prepared to react when a natural hazard event occurs. Natural hazard awareness and preparedness training and education often takes place through informal learning at science centers and formal k-12 education programs as well as through awareness raising via strategically placed informational tsunami warning signs and placards. Museums and science centers are influential in raising science literacy within a community, however can science centers enhance earthquake and tsunami resiliency by providing hazard science content and preparedness exhibits? Museum docents and informal educators are uniquely situated within the community. They are transmitters and translators of science information to broad audiences. Through interaction with the public, docents are well positioned to be informants of the knowledge beliefs, and feelings of science center visitors. They themselves are life-long learners, both constantly learning from the museum content around them and sharing this content with visitors. They are also members of a community where they live. In-depth interviews with museum informal educators and docents were conducted at a science center in coastal Pacific Northwest. This region has a potential to be struck by a great 9+ Mw earthquake and subsequent tsunami. During the interviews, docents described how they applied learning from natural hazard exhibits at a science visitor center to their daily lives. During the individual interviews, the museum docents described their awareness (knowledge, attitudes, and behaviors) of natural hazards where they live and work, the feelings evoked as they learned about their hazard vulnerability, the extent to which they applied this learning and awareness to their lives, such as creating an evacuation plan, whether

  11. Tailored ramp wave generation in gas gun experiments

    2015-01-01

    Full Text Available Gas guns are traditionally used as platforms to introduce a planar shock wave to a material using plate impact methods, generating states on the Hugoniot. The ability to deliver a ramp wave to a target during a gas gun experiment enables access to different regions of the equation-of-state surface, making it a valuable technique for characterising material behaviour. Previous techniques have relied on the use of multi-material impactors to generate a density gradient, which can be complex to manufacture. In this paper we describe the use of an additively manufactured steel component consisting of an array of tapered spikes which can deliver a ramp wave over ∼ 2 μs. The ability to tailor the input wave by varying the component design is discussed, an approach which makes use of the design freedom offered by additive manufacturing techniques to rapidly iterate the spike profile. Results from gas gun experiments are presented to evaluate the technique, and compared with 3D hydrodynamic simulations.

  12. New theoretical framework for designing nonionic surfactant mixtures that exhibit a desired adsorption kinetics behavior.

    How does one design a surfactant mixture using a set of available surfactants such that it exhibits a desired adsorption kinetics behavior? The traditional approach used to address this design problem involves conducting trial-and-error experiments with specific surfactant mixtures. This approach is typically time-consuming and resource-intensive and becomes increasingly challenging when the number of surfactants that can be mixed increases. In this article, we propose a new theoretical framework to identify a surfactant mixture that most closely meets a desired adsorption kinetics behavior. Specifically, the new theoretical framework involves (a) formulating the surfactant mixture design problem as an optimization problem using an adsorption kinetics model and (b) solving the optimization problem using a commercial optimization package. The proposed framework aims to identify the surfactant mixture that most closely satisfies the desired adsorption kinetics behavior subject to the predictive capabilities of the chosen adsorption kinetics model. Experiments can then be conducted at the identified surfactant mixture condition to validate the predictions. We demonstrate the reliability and effectiveness of the proposed theoretical framework through a realistic case study by identifying a nonionic surfactant mixture consisting of up to four alkyl poly(ethylene oxide) surfactants (C(10)E(4), C(12)E(5), C(12)E(6), and C(10)E(8)) such that it most closely exhibits a desired dynamic surface tension (DST) profile. Specifically, we use the Mulqueen-Stebe-Blankschtein (MSB) adsorption kinetics model (Mulqueen, M.; Stebe, K. J.; Blankschtein, D. Langmuir 2001, 17, 5196-5207) to formulate the optimization problem as well as the SNOPT commercial optimization solver to identify a surfactant mixture consisting of these four surfactants that most closely exhibits the desired DST profile. Finally, we compare the experimental DST profile measured at the surfactant mixture condition

    Metformin (Met) is an anti-hyperglycemic and potential anti-cancer agent which may exert its anti-proliferative effects via the induction of energetic stress. In this study we investigated the in vitro and in vivo efficacy of Met against the larval stage of Echinococcus granulosus. Metformin showed significant dose- and time-dependent killing effects on in vitro cultured protoscoleces and metacestodes. Notably, the combination of Met together with the minimum effective concentration of ABZSO had a synergistic effect after days 3 and 12 on metacestodes and protoscoleces, respectively. Oral administration of Met (50 mg/kg/day) in E. granulosus-infected mice was highly effective in reducing the weight and number of parasite cysts, yet its combination with the lowest recommended dose of ABZ (5 mg/kg/day) was even more effective. Coincidentally, intracystic Met accumulation was higher in animals treated with both drugs compared to those administered Met alone. Furthermore, the safe plant-derived drug Met exhibited remarkable chemopreventive properties against secondary hydatidosis in mice. In conclusion, based on our experimental data, Met emerges as a promising anti-echinococcal drug as it has proven to efficiently inhibit the development and growth of the E. granulosus larval stage and its combination with ABZ may improve the current anti-parasitic therapy.

  14. Apoptotic HPV positive cancer cells exhibit transforming properties.

    Directory of Open Access Journals (Sweden)

    Emilie Gaiffe

    Full Text Available Previous studies have shown that DNA can be transferred from dying engineered cells to neighboring cells through the phagocytosis of apoptotic bodies, which leads to cellular transformation. Here, we provide evidence of an uptake of apoptotic-derived cervical cancer cells by human mesenchymal cells. Interestingly, HeLa (HPV 18+ or Ca Ski (HPV16+ cells, harboring integrated high-risk HPV DNA but not C-33 A cells (HPV-, were able to transform the recipient cells. Human primary fibroblasts engulfed the apoptotic bodies effectively within 30 minutes after co-cultivation. This mechanism is active and involves the actin cytoskeleton. In situ hybridization of transformed fibroblasts revealed the presence of HPV DNA in the nucleus of a subset of phagocytosing cells. These cells expressed the HPV16/18 E6 gene, which contributes to the disruption of the p53/p21 pathway, and the cells exhibited a tumorigenic phenotype, including an increased proliferation rate, polyploidy and anchorage independence growth. Such horizontal transfer of viral oncogenes to surrounding cells that lack receptors for HPV could facilitate the persistence of the virus, the main risk factor for cervical cancer development. This process might contribute to HPV-associated disease progression in vivo.

    Full Text Available Abstract Background To expand on the range of products which can be obtained from lignocellulosic biomass, the lignin component should be utilized as feedstock for value-added chemicals such as substituted aromatics, instead of being incinerated for heat and energy. Enzymes could provide an effective means for lignin depolymerization into products of interest. In this study, soil bacteria were isolated by enrichment on Kraft lignin and evaluated for their ligninolytic potential as a source of novel enzymes for waste lignin valorization. Results Based on 16S rRNA gene sequencing and phenotypic characterization, the organisms were identified as Pandoraea norimbergensis LD001, Pseudomonas sp LD002 and Bacillus sp LD003. The ligninolytic capability of each of these isolates was assessed by growth on high-molecular weight and low-molecular weight lignin fractions, utilization of lignin-associated aromatic monomers and degradation of ligninolytic indicator dyes. Pandoraea norimbergensis LD001 and Pseudomonas sp. LD002 exhibited best growth on lignin fractions, but limited dye-decolourizing capacity. Bacillus sp. LD003, however, showed least efficient growth on lignin fractions but extensive dye-decolourizing capacity, with a particular preference for the recalcitrant phenothiazine dye class (Azure B, Methylene Blue and Toluidene Blue O. Conclusions Bacillus sp. LD003 was selected as a promising source of novel types of ligninolytic enzymes. Our observations suggested that lignin mineralization and depolymerization are separate events which place additional challenges on the screening of ligninolytic microorganisms for specific ligninolytic enzymes.

    Antimicrobial peptides (AMPs) occur widely in nature and have been studied for their therapeutic potential. AMPs are of interest due to the large number of possible chemical structural combinations using natural and unnatural amino acids, with varying effects on their biological activities. Using physicochemical properties from known naturally occurring amphipathic cationic AMPs, several hydrocarbon-stapled lipopeptides (HSLPs) were designed, synthesized, and tested for antimicrobial properties. Peptides were chemically modified by N-terminal acylation, C-terminal amidation, and some were hydrocarbon stapled by intramolecular olefin metathesis. The effects of peptide length, amphipathic character, and stapling on antimicrobial activity were tested against Escherichia coli, three species of Gram-positive bacteria (Staphylococcus aureus, Bacillus megaterium, and Enterococcus faecalis), and two strains of Candida albicans. Peptides were shown to disrupt liposomes of different phospholipid composition, as measured by leakage of a fluorescent compound from vesicles. Peptides with (S)-2-(4'-pentenyl)-alanine substituted for L-alanine in a reference peptide showed a marked increase in antimicrobial activity, hemolysis, and membrane disruption. Stapled peptides exhibited slightly higher antimicrobial potency; those with greatest hydrophobic character showed the greatest hemolysis and liposome leakage, but lower antimicrobial activity. The results support a model of HSLPs as membrane-disruptive AMPs with potent antimicrobial activity and relatively low hemolytic potential at biologically active peptide concentrations.

    Full Text Available This article compares the histories of two museums of polar exploration, both founded in the 1930s but based on well-known expeditions dating back to the decades around 1900. The first is the Fram Museum in Oslo, centered around the famous Norwegian polar ship, the second is the Andrée Museum in Gränna, com-bining accounts of the ill-fated balloon expedition with a polar centre reflecting more recent polar research activities. The aim of the article is to analyze the relationship between museum and narra-tive. Museums are shapers of narrative but at the same time shaped by the narra-tives they relate. The article explores the symbolic and medialized dimensions of polar research, expressed in museums, as well as the way in which museums in-terrelate with national identities and self-images. What does it mean to be a modern polar nation? And how is such an identity expressed in cultural terms? In which ways can museum institutions and exhibi-tions be used as means for such expressions? And how do “the grand narratives” of Sweden and Norway relate to the epic representations of polar activities, pre-sented by the museums?

    The present study was conducted to evaluate the methanolic extract of Piper betle leaves (MPBL) and its organic fractions with regard to antitumor activity against Ehrlich ascites carcinoma (EAC) in Swiss albino mice and to confirm their antioxidant activities. At 24 h post-intraperitoneal inoculation of tumor cells into mice, extracts were administered at 25, 50 and 100 mg/kg body weight for nine consecutive days. The antitumor effects of the extracts were then assessed according to tumor volume, packed cell count, viable and non-viable tumor cell count, median survival time and increase in life span of EAC-bearing mice. Next, hematological profiles and serum biochemical parameters were calculated, and antioxidant properties were assessed by estimating lipid peroxidation, reduced glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT) levels. MPBL and the ethylacetate fraction (EPBL) at a dose of 100 mg/kg induced a significant decrease in tumor volume, packed cell volume and viable cell count and increased the life span of the EAC-bearing mice (PPiper betle extracts exhibit significant antitumor activity, which may be attributed to the augmentation of endogenous antioxidant potential.

    Cytoskeletal changes in transformed cells (LM-51) eshibiting obviously metastatic capabilities were investigated by utilization of double-fluorescent labelling through combinations of:(1) tubulin indirect immunofluorescence plus Rhodamine-phalloidin staining of F-actins;(2) indirect immunofluorescent staining with α-actinin polyclonal-and vinculin monoclonal antibodies.The LM-51 cells which showed metastatic index of >50% were derived from lung metastasis in nude mice after subcutaneous inoculation of human highly metastatic tumor DNA transfected NIH3T3 cell transformants.The parent NIH3T3 cells exhibited well-organized microtubules,prominent stress fibers and adhesion plaques while their transformants showed remarkable cytoskeletal alterations:(1)reduced microtubules but increased MTOC fluorescence;(2)disrupted stress fibers and fewer adhesion plaques with their protein components redistributed in the cytoplasm;(3)Factin-and α-actinin/vinculin aggregates appeared in the cytoplasm.These aggregates were dot-like,varied in size(0.1-0.4μm) and number,located near the ventral surface of the cells.TPA-induced actin/vinculin bodies were studied too.Indications that actin and α-actinin/vinculin redistribution might be important alterations involved in the expression of metastatic capabilities of LM-51 transformed cells were discussed.

    When mature adipocytes are subjected to an in vitro dedifferentiation strategy referred to as ceiling culture, these mature adipocytes can revert to a more primitive phenotype and gain cell proliferative ability. We refer to these cells as dedifferentiated fat (DFAT) cells. In the present study, we examined the multilineage differentiation potential of DFAT cells. DFAT cells obtained from adipose tissues of 18 donors exhibited a fibroblast-like morphology and sustained high proliferative activity. Flow cytometric analysis revealed that DFAT cells comprised a highly homogeneous cell population compared with that of adipose-derived stem/stromal cells (ASCs), although the cell-surface antigen profile of DFAT cells was very similar to that of ASCs. DFAT cells lost expression of mature adipocytes marker genes but retained or gained expression of mesenchymal lineage-committed marker genes such as peroxisome proliferator-activated receptor gamma (PPARgamma), RUNX2, and SOX9. In vitro differentiation analysis revealed that DFAT cells could differentiate into adipocytes, chondrocytes, and osteoblasts under appropriate culture conditions. DFAT cells also formed osteoid matrix when implanted subcutaneously into nude mice. In addition, clonally expanded porcine DFAT cells showed the ability to differentiate into multiple mesenchymal cell lineages. These results indicate that DFAT cells represent a type of multipotent progenitor cell. The accessibility and ease of culture of DFAT cells support their potential application for cell-based therapies.

    Full Text Available PMD (Pelizaeus–Merzbacher disease, a CNS (central nervous system disease characterized by shortened lifespan and severe neural dysfunction, is caused by mutations of the PLP1 (X-linked myelin proteolipid protein gene. The majority of human PLP1 mutations are caused by duplications; almost all others are caused by missense mutations. The cellular events leading to the phenotype are unknown. The same mutations in non-humans make them ideal models to study the mechanisms that cause neurological sequelae. In the present study we show that mice with Plp1 duplications (Plp1tg have major mitochondrial deficits with a 50% reduction in ATP, a drastically reduced mitochondrial membrane potential and increased numbers of mitochondria. In contrast, the jp (jimpy mouse with a Plp1 missense mutation exhibits normal mitochondrial function. We show that PLP in the Plp1tg mice and in Plp1-transfected cells is targeted to mitochondria. PLP has motifs permissive for insertion into mitochondria and deletions near its N-terminus prevent its co-localization to mitochondria. These novel data show that Plp1 missense mutations and duplications of the native Plp1 gene initiate uniquely different cellular responses.

    A simple fluid, in a microscopic capillary capped at one end, is studied by means of fundamental measure density functional. The model represents a single, infinitely long nanogroove with long-range wall-fluid attractive (dispersion) forces. It is shown that the presence or absence of hysteresis in adsorption isotherms is determined by wetting properties of the wall as follows: Above wetting temperature, Tw, appropriate to a single wall of the groove, the adsorption is a continuous process corresponding to a rise of a meniscus from the capped to the open end of the groove. For a sufficiently deep capillary, the meniscus rise is shown to be a steep, yet continuous process taking place near the capillary condensation of a corresponding slit. However, for temperatures lower than Tw the condensation exhibits a first-order transition accompanied by hysteresis of the adsorption isotherm. Finally, it is shown that hysteresis may occur even for T > Tw as a consequence of prewetting on the side and bottom walls of the groove.

    Although corrosion resistant bare metal stents are considered generally effective, their permanent presence in a diseased artery is an increasingly recognized limitation due to the potential for long-term complications. We previously reported that metallic zinc exhibited an ideal biocorrosion rate within murine aortas, thus raising the possibility of zinc as a candidate base material for endovascular stenting applications. This study was undertaken to further assess the arterial biocompatibility of metallic zinc. Metallic zinc wires were punctured and advanced into the rat abdominal aorta lumen for up to 6.5months. This study demonstrated that metallic zinc did not provoke responses that often contribute to restenosis. Low cell densities and neointimal tissue thickness, along with tissue regeneration within the corroding implant, point to optimal biocompatibility of corroding zinc. Furthermore, the lack of progression in neointimal tissue thickness over 6.5months or the presence of smooth muscle cells near the zinc implant suggest that the products of zinc corrosion may suppress the activities of inflammatory and smooth muscle cells.

    To extend density limits in magnetic recording industry, two separate strategies were developed to build the storage bit in last decade, introduction of perpendicular magnetic anisotropy (PMA) and adoption of ferrimagnetism/antiferromagnetism. Meanwhile, these properties significantly improve device performance, such as reducing spin-transfer torque energy consumption and decreasing signal-amplitude-loss. However, materials combining PMA and antiferromagnetism rather than transition-metal/rare-earth system were rarely developed. Here, we develop a new type of ferrimagnetic superlattice exhibiting PMA based on abundant Heusler alloy families. The superlattice is formed by [MnGa/Co2FeAl] unit with their magnetizations antiparallel aligned. The effective anisotropy (Kueff) over 6 Merg/cm3 is obtained, and the SL can be easily built on various substrates with flexible lattice constants. The coercive force, saturation magnetization and Kueff of SLs are highly controllable by varying the thickness of MnGa and Co2FeAl layers. The SLs will supply a new choice for magnetic recording and spintronics memory application such as magnetic random access memory.

  6. Short and long term measures of anxiety exhibit opposite results.

    Full Text Available Animal models of human diseases of the central nervous system, generalized anxiety disorder included, are essential for the study of the brain-behavior interface and obligatory for drug development; yet, these models fail to yield new insights and efficacious drugs. By increasing testing duration hundredfold and arena size tenfold, and comparing the behavior of the common animal model to that of wild mice, we raise concerns that chronic anxiety might have been measured at the wrong time, for the wrong duration, and in the wrong animal. Furthermore, the mice start the experimental session with a short period of transient adaptation to the novel environment (habituation period and a long period reflecting the respective trait of the mice. Using common measures of anxiety reveals that mice exhibit opposite results during these periods suggesting that chronic anxiety should be measured during the post-habituation period. We recommend tools for measuring the transient period, and provide suggestions for characterizing the post habituation period.

  7. A new theory of doped manganites exhibiting colossal magnetoresistance

    Rare earth manganites doped with alkaline earths, namely Re1-AMnO3, exhibit colossal magnetoresistance, metal insulator transitions, competing magnetic, orbital and charge ordering, and many other interesting but poorly understood phenomena. In this article I outline our recent theory based on the idea that in the presence of strong Jahn–Teller, Coulomb and Hund’s couplings present in these materials, the low-energy electronic states dynamically reorganize themselves into two sets: one set (ℓ) which are polaronic, i.e., localized and accompanied by large local lattice distortion, and another (b) which are non-polaronic and band-like. The coexistence of the radically different ℓ and states, and the sensitive dependence of their relative energies and occupation upon doping , temperature , magnetic field , etc., underlies the unique effects seen in manganites. I present results from strong correlation calculations using dynamical mean-field theory and simulations on a new 2-fluid model which accord with a variety of observations.

  10. Flexible flapping wings can exhibit quasi-periodic motion!

    2016-10-01

    The dynamics of a flexible flapping wing is investigated by modelling it as a coupled nonlinear fluid-structure interaction (FSI) system in the low Reynolds number flow regime in accordance to the flight of flapping wing micro air vehicles (MAVs). A bifurcation analysis, by varying the free-stream wind velocity (U ∞) as the control parameter, revealed the presence of a new dynamics in the form of a quasi-periodic attractor in the flapping wing motion. The structural and aerodynamic nonlinearities present in the system cause a supercritical Hopf bifurcation, where stable limit cycle oscillation emerges from fixed point response beyond a critical value of the free-stream velocity. Further increasing the control parameter, another bifurcation named Neimark-Sacker bifurcation takes place and as a result, the flapping wing exhibits quasi-periodic motion. The presence of Neimark-Sacker bifurcation in the flapping flow-field dynamics is an interesting find and the present work focuses on it's associated dynamical behaviour. Various dynamical system tools like frequency spectra, phase space, Poincaré section, first return map have been implemented successfully to confirm the presence of quasi-periodicity.

    On 5 September 2000,a number of events compatible with the production of a Higgs boson with mass around 114-115 GeV was reported in the combined results of the four LEP experiments,ALEPH,DELPHI,L3 and OPAL.However, these events are also compatible with originating from other known Standard Model processes.As a consequence, it is at present impossible either to rule out or confirm the existence of a 114-115 GeV Higgs boson.The prolongation of LEP running through October 2000 is the response to this tantalizing situation.

    Beyond most ephemeral artwork a memory remains in the mind of the observer and this forms part of the legacy of the fleeting event. However, memory is mostly a personal experience, that shifts, mutates, and fades over time to become distant, different to its origin, and in this way its archival potential is unreliable. To overcome this dilemma a variety of lens-based archival methods have become the tradition of recording the ‘actual’ event in as far as it is possible. Although a recorder, of...

    2016-06-01

    By working together, social insects achieve tasks that are beyond the reach of single individuals. A striking example of collective behaviour is self-assembly, a process in which individuals link their bodies together to form structures such as chains, ladders, walls or rafts. To get insight into how individual behavioural variation affects the formation of self-assemblages, we investigated the presence of task specialization and the role of past experience in the construction of ant rafts. We subjected groups of Formica selysi workers to two consecutive floods and monitored the position of individuals in rafts. Workers showed specialization in their positions when rafting, with the same individuals consistently occupying the top, middle, base or side position in the raft. The presence of brood modified workers' position and raft shape. Surprisingly, workers' experience in the first rafting trial with brood influenced their behaviour and raft shape in the subsequent trial without brood. Overall, this study sheds light on the importance of workers' specialization and memory in the formation of self-assemblages.

    Research on hybridization between species provides unparalleled insights into the pre- and postzygotic isolating mechanisms that drive speciation. In social organisms, colony-level incompatibilities may provide additional reproductive barriers not present in solitary species, and hybrid zones offer an opportunity to identify these barriers. Here, we use genotyping-by-sequencing to sequence hundreds of markers in a hybrid zone between two socially polymorphic ant species, Formica selysi and Formica cinerea. We characterize the zone, determine the frequency of hybrid workers, infer whether hybrid queens or males are produced and investigate whether hybridization is influenced by colony social organization. We also compare cuticular hydrocarbon profiles and aggression levels between the two species. The hybrid zone exhibits a mosaic structure. The asymmetric distribution of hybrids skewed towards F. cinerea suggests a pattern of unidirectional nuclear gene flow from F. selysi into F. cinerea. The occurrence of backcrossed individuals indicates that hybrid queens and/or males are fertile, and the presence of the F. cinerea mitochondrial haplotype in 97% of hybrids shows that successful F1 hybrids will generally have F. cinerea mothers and F. selysi fathers. We found no evidence that social organization contributes to speciation, because hybrids occur in both single-queen and multiple-queen colonies. Strongly differentiated cuticular hydrocarbon profiles and heightened interspecific aggression further reveal that species recognition cues are both present and perceived. The discovery of fertile hybrids and asymmetrical gene flow is unusual in ants, and this hybrid zone will therefore provide an ideal system with which to investigate speciation in social insects.

  16. Arabidopsis mutant bik1 exhibits strong resistance to Plasmodiophora brassicae

    2016-09-01

    Full Text Available Botrytis-induced kinase1 (BIK1, a receptor-like cytoplasmic kinase, plays an important role in resistance against pathogens and insects in Arabidopsis thaliana. However, it remains unknown whether BIK1 functions against Plasmodiophora brassicae, an obligate biotrophic protist that attacks cruciferous plants and induces gall formation on roots. Here, we investigated the potential roles of receptors FLS2, BAK1 and BIK1 in the infection of P. brassicae cruciferous plants. Wild-type plants, fls2 and bak1 mutants showed typical symptom on roots, and the galls were filled with large quantities of resting spores, while bik1 mutant plants exhibited strong resistance to P. brassicae. Compared with that of the wild-type plants, the root hair and cortical infection rate of bik1 mutant were significantly reduced by about 40-50%. A considerable portion of bik1 roots failed to form typical galls. Even if some small galls were formed, they were filled with multinucleate secondary plasmodia. The bik1 plants accumulated less reactive oxygen species (ROS at infected roots than other mutants and wild-type plants. Exogenous salicylic acid (SA treatment alleviated the clubroot symptoms in wild-type plants, and the expression of the SA signaling marker gene PR1 was significantly increased in bik1. Both sid2 (salicylic acid induction-deficient 2 and npr1-1 (non-expresser of PR genes that regulate systemic acquired resistance (SAR mutants showed increased susceptibility to P. brassicae compared with wild-type plants. These results suggest that the resistance of bik1 to P. brassicae is possibly mediated by SA inducible mechanisms enhance the resistance to clubroot disease.

    2009-12-01

    Full Text Available A museum is not only a physical place, a mere container of fragments of the cultural heritage. It is above all a unity of knowledge whose task of scientific research and analysis of the collections leads to an original interpretation of the world, to a specific culture, typical of each museum. Through its permanent exhibitions or any other means at its disposal, each museum conveys its cultural specificity to the visitor, a specificity which is different to that of other museums and does not intend to be objective. This paper aims to prove all the above by showing how, in different times and places, three important museums displayed three examples of evolution obtained form paleontology developing a totally subjective interpretation of the evolutionary process.

    El museo no es sólo un lugar físico, un simple contenedor de fragmentos del patrimonio cultural, es, sobretodo, una unidad de conocimiento cuya labor de investigación científica y análisis de las colecciones conduce a una interpretación del mundo totalmente original, a una cultura propia de cada museo. Utilizando las exposiciones permanentes, o cualquier otro medio a su disposición, cada museo comunica al público su especifidad cultural, que es diversa de la de otros museos y no quiere ser objetiva. Esto es cuanto el artículo pretende demostrar ilustrando cómo, en tiempos y lugares diferentes, tres grandes instituciones museísticas mostraron al público tres ejemplos de evolución obtenida de la paleontología desarrollando una interpretación totalmente subjetiva del proceso evolutivo.

    AIM: To compare the demographic and clinical features of different manometric subsets of ineffective oesophageal motility (IOM; defined as ≥30% wet swallows with distal contractile amplitude <30 mmHg), and to determine whether the prevalence of gastro-oesophageal reflux differs between IOM subsets.METHODS: Clinical characteristics of manometric subsets were determined in 100 IOM patients (73 female, median age 58 years) and compared to those of 100 age-and gender-matched patient controls with oesophageal symptoms, but normal manometry. Supine oesophageal manometry was performed with an eight-channel DentSleeve water-perfused catheter, and an ambulatory pH study assessed gastrooesophageal reflux.RESULTS: Patients in the IOM subset featuring a majority of low-amplitude simultaneous contractions (LASC) experienced less heartburn (prevalence 26%), but more dysphagia (57%) than those in the IOM subset featuring low-amplitude propagated contractions (LAP; heartburn 70%, dysphagia 24%; both P≤0.01). LASC patients also experienced less heartburn and more dysphagia than patient controls (heartburn 68%, dysphagia 11%; both P<0.001). The prevalence of heartburn and dysphagia in IOM patients featuring a majority of non-transmitted sequences (NT) was 54% (P=0.04 vs LASC) and 36% (P<0.01 vs controls), respectively. No differences in age and gender distribution, chest pain prevalence, acid exposure time (AET) and symptom/reflux association existed between IOM subsets, or between subsets and controls.CONCLUSION: IOM patients with LASC exhibit a different symptom profile to those with LAP, but do not differ in gastro-oesophageal reflux prevalence. These findings raise the possibility of different pathophysiological mechanisms in IOM subsets, which warrants further investigation.

  19. Murine and human CFTR exhibit different sensitivities to CFTR potentiators.

    2015-10-01

    Development of therapeutic molecules with clinical efficacy as modulators of defective CFTR includes efforts to identify potentiators that can overcome or repair the gating defect in mutant CFTR channels. This has taken a great leap forward with the identification of the potentiator VX-770, now available to patients as "Kalydeco." Other small molecules with different chemical structure also are capable of potentiating the activity of either wild-type or mutant CFTR, suggesting that there are features of the protein that may be targeted to achieve stimulation of channel activity by structurally diverse compounds. However, neither the mechanisms by which these compounds potentiate mutant CFTR nor the site(s) where these compounds bind have been identified. This knowledge gap partly reflects the lack of appropriate experimental models to provide clues toward the identification of binding sites. Here, we have compared the channel behavior and response to novel and known potentiators of human CFTR (hCFTR) and murine (mCFTR) expressed in Xenopus oocytes. Both hCFTR and mCFTR were blocked by GlyH-101 from the extracellular side, but mCFTR activity was increased with GlyH-101 applied directly to the cytoplasmic side. Similarly, glibenclamide only exhibited a blocking effect on hCFTR but both blocked and potentiated mCFTR in excised membrane patches and in intact oocytes. The clinically used CFTR potentiator VX-770 transiently increased hCFTR by ∼13% but potentiated mCFTR significantly more strongly. Our results suggest that mCFTR pharmacological sensitivities differ from hCFTR, which will provide a useful tool for identifying the binding sites and mechanism for these potentiators.

  20. The 'electric stroke' and the 'electric spark': anatomists and eroticism at George Baker's electric eel exhibition in 1776 and 1777.

    2010-09-01

    In 1776 and 1777 five living electric eels exhibited in London became a sensational spectacle that appealed to anatomists, electricians and connoisseurs of erotica. George Baker's exhibition made visible the 'electric spark' of the electrical eel and a series of experiments were both witnessed by and participated in by members of the Royal Society and the metropolitan elite. Some participants even grasped the eels firmly in their hands and felt the 'electric stroke' of the eel in addition to observing the spark. In their observation of the electric eel some of these spectators transposed the vivid electric spark from the sphere of electricians and anatomists into that of satirical and erotic literature. Here the erotic electric eel proliferated in the literature and the eel took on quite different connotations that nonetheless were reliant on readers knowledge and experience of the exhibition, experiments and the preoccupations of anatomists. George Baker's electric eel exhibition of 1776 and 1777 is then instructive in exploring the production and circulation of knowledge in Georgian Britain. The story of the electric eel in Georgian culture charts the creation of the electric spark and stroke as objects of observation and encounter, their exhibitionary context, and finally their divergent meanings as the electric eel became erotically charged for a metropolitan masculine elite.

    The purpose of the work is to enhance remote operations of robotic systems for D&D tasks by extending teleoperation with semi-autonomous functions. The work leverages the $1.2M dual-arm work platform (DAWP) developed with broad participation for the CP5 D&D, as well as 2,000 hr DAWP D&D operational experience. We propose to develop a reactive, agent-based control architecture well suited to unstructured and unpredictable environments, and robot control technology, which implements a virtual fixture that can be used to guide the application of tools with force-feedback control. Developed methodologies will be implemented using a structured light sensor and robot hand controller on the dual-arm system.

    2014-01-01

    Geometric confinement plays an important role in the dynamics of natural and synthetic microswimmers from bacterial cells to self-propelled particles in high-throughput microfluidic devices. However, little is known about the effects of geometric confinement on the emergent global patterns in such self-propelled systems. Recent experiments on bacterial cells give conflicting reports of cells spontaneously organizing into a spiral vortex in a thin cylindrical droplet and cells aggregating at the inner boundary in a spherical droplet. We investigate here, in an idealized physical model, the interplay between geometric confinement and level of flagellar activity on the emergent collective patterns. We show that decreasing flagellar activity induces a hydrodynamically-triggered transition in confined microswimmers from swirling to global circulation (vortex) to boundary aggregation and clustering. These results highlight that the complex interplay between confinement, flagellar activity and hydrodynamic flows in ...

  4. fNIRS exhibits weak tuning to hand movement direction.

    2012-01-01

    Functional near-infrared spectroscopy (fNIRS) has become an established tool to investigate brain function and is, due to its portability and resistance to electromagnetic noise, an interesting modality for brain-machine interfaces (BMIs). BMIs have been successfully realized using the decoding of movement kinematics from intra-cortical recordings in monkey and human. Recently, it has been shown that hemodynamic brain responses as measured by fMRI are modulated by the direction of hand movements. However, quantitative data on the decoding of movement direction from hemodynamic responses is still lacking and it remains unclear whether this can be achieved with fNIRS, which records signals at a lower spatial resolution but with the advantage of being portable. Here, we recorded brain activity with fNIRS above different cortical areas while subjects performed hand movements in two different directions. We found that hemodynamic signals in contralateral sensorimotor areas vary with the direction of movements, though only weakly. Using these signals, movement direction could be inferred on a single-trial basis with an accuracy of ∼65% on average across subjects. The temporal evolution of decoding accuracy resembled that of typical hemodynamic responses observed in motor experiments. Simultaneous recordings with a head tracking system showed that head movements, at least up to some extent, do not influence the decoding of fNIRS signals. Due to the low accuracy, fNIRS is not a viable alternative for BMIs utilizing decoding of movement direction. However, due to its relative resistance to head movements, it is promising for studies investigating brain activity during motor experiments.

    Particle-filled elastomers are commonly used as engineering components due to their ability to provide structural support via their elastic mechanical response. Even small amounts of particle fillers are known to increase the mechanical strength of elastomers due to polymer-filler interactions. In this work, the shock response of two filled (SiO2 or silica and KevlarTMfillers) ethylene-propylene-diene (EPDM) rubbers were studied using single and two-stage gas gun-driven plate impact experiments. Hugoniot states were determined using standard plate impact methods. Both filled-EPDM elastomers exhibit high compressibility under shock loading and have a response similar to adiprene rubber.

    2016-04-01

    In the last decades, the demand and acknowledged importance of science outreach, in general and geophysics in particular, has grown, as demonstrated by many international and national projects and other activities performed by research institutes. The National Institute for Earth Physics (NIEP) from Romania is the leading national institution on earthquake monitoring and research, having at the same time a declared focus on informing and educating a wide audience about geosciences and especially seismology. This is more than welcome, since Romania is a very active country from a seismological point of view, but not too reactive when it comes to diminishing the possible effect of a major earthquake. Over the last few decades, the country has experienced several major earthquakes which have claimed thousands of lives and millions in property damage (1940; 1977; 1986 and 1990 Vrancea earthquakes). In this context, during a partnership started in 2014 together with the National Art University and Siveco IT company, a group of researchers from NIEP initiated the MOBile Earthquake Exhibition (MOBEE) project. The main goal was to design a portable museum to bring on the road educational activities focused on seismology, seismic hazard and Earth science. The exhibition is mainly focused on school students of all ages as it explains the main topics of geophysics through a unique combination of posters, digital animations and apps, large markets and exciting hand-on experiments, 3D printed models and posters. This project is singular in Romania and aims to transmit properly reviewed actual information, regarding the definition of earthquakes, the way natural hazards can affect people, buildings and the environment and the measures to be taken for prevent an aftermath. Many of the presented concepts can be used by teachers as a complementary way of demonstrating physics facts and concepts and explaining processes that shape the dynamic Earth features. It also involves

    This paper presents enhanced remote manipulation of tools for D&D tasks by extending teleoperation with teleautonomy and tele-collaboration. This work builds on a reactive, agent-based control architecture, which is well suited to unstructured and unpredictable environments, and cobot control technology, which implements a virtual fixture that can be used to guide the application of tools with passive force-feedback control. Developed methodologies are tested using simulation, and then planned to be implemented using a structured light sensor and cobot hand controller on a dual-arm system to measure the enhanced performance of key tool operations that are tedious and difficult to perform purely by teleoperation. This work significantly leverages some 2000 hours of operational experience gained during the D&D of the CP-5 reactor at ANL using a dual-arm remote manipulator system, as well as DOE's investment in the dual-arm system itself, which will serve as a test bed for the proposed investigations.

  14. Variation in acoustic signalling traits exhibits footprints of sexual selection.

    Science.gov (United States)

    Reinhold, Klaus

    2011-03-01

    Phenotypic variation is ubiquitous in nature and a precondition for adaptive evolution. However, theory predicts that the extent of phenotypic variation should decrease with increasing strength of selection on a trait. Comparative analyses of trait variability have repeatedly used this expectation to infer the type or strength of selection. Yet, the suggested influence of selection on trait variability has rarely been tested empirically. In the present study, I compare estimates of sexual selection strength and trait variability from published data. I constricted the analysis to acoustic courtship traits in amphibians and insects with known variability and corresponding results of female binary choice experiments on these traits. Trait variability and strength of sexual selection were significantly correlated, and both were correlated with signal duration. Because traits under stronger selection had lower variation even after the effect of signal duration was eliminated, I conclude that traces of the strength of selection can be observed with respect to variation of acoustic signaling traits in insects and amphibians. The analysis also shows that traits under stabilizing selection have significantly lower phenotypic variability than traits under directional selection.

  15. EXPOSING ETHNOGRAPHIC KNOWLEDGE: MUSEOLOGICAL PERSPECTIVES ON DIGITAL MEDIA AND EXHIBITION

    Full Text Available As tecnologias digitais têm diversificado os lugares da museologia e renovado as práticas de instituições comprometidas na tarefa de mapear os conhecimentos. De fato, as imagens digitais se prestam a todos os usos: arquivadas, exibidas, editadas, elas podem servir a simular, explicar, demonstrar, ou favorecer ao público as possibilidades de exploração. Mas além dessas semelhanças funcionais com as técnicas museológicas, a predominância dos meios digitais pode suscitar preocupações acerca do risco de confusão ou de nivelamento das diferenças e das singularidades nas realidades apresentadas. A experiência concreta de montagem de uma exposição, a partir da etnografia da ocupação de cabanas abandonadas por migrantes sem abrigo, nos levou, o sociólogo Nasser Tafferant e eu, a considerar as limitações das produções digitais no âmbito da etnografia. A encenação das condições precárias de moradia desses migrantes convocava as dimensões sensíveis, físicas, corporais do trabalho etnográfico para torná-las perceptíveis num espaço concreto do percurso expositivo. Estamos apostando que uma forma original de conhecimento pode emergir dessa aproximação da pesquisa etnográfica através da mídia da exposição.

    Bacteria will accompany humans in our exploration of space, making it of importance to study their adaptation to the microgravity environment. To investigate potential phenotypic changes for bacteria grown in space, Escherichia coli was cultured onboard the International Space Station with matched controls on Earth. Samples were challenged with different concentrations of gentamicin sulfate to study the role of drug concentration on the dependent variables in the space environment. Analyses included assessments of final cell count, cell size, cell envelope thickness, cell ultrastructure, and culture morphology. A 13-fold increase in final cell count was observed in space with respect to the ground controls and the space flight cells were able to grow in the presence of normally inhibitory levels of gentamicin sulfate. Contrast light microscopy and focused ion beam/scanning electron microscopy showed that, on average, cells in space were 37% of the volume of their matched controls, which may alter the rate of molecule-cell interactions in a diffusion-limited mass transport regime as is expected to occur in microgravity. TEM imagery showed an increase in cell envelope thickness of between 25 and 43% in space with respect to the Earth control group. Outer membrane vesicles were observed on the spaceflight samples, but not on the Earth cultures. While E. coli suspension cultures on Earth were homogenously distributed throughout the liquid medium, in space they tended to form a cluster, leaving the surrounding medium visibly clear of cells. This cell aggregation behavior may be associated with enhanced biofilm formation observed in other spaceflight experiments.

    2014-01-01

    Human factors analyses have been used to improve efficiency and safety in various work environments. Although generally limited to humans, the universality of these analyses allows for their formal application to a much broader domain. This paper outlines a model for the use of human factors to enhance zoo exhibits and optimize spaces for all user groups; zoo animals, zoo visitors, and zoo staff members. Zoo exhibits are multi-faceted and each user group has a distinct set of requirements that can clash or complement each other. Careful analysis and a reframing of the three groups as interdependent coworkers can enhance safety, efficiency, and experience for all user groups. This paper details a general creation and specific examples of the use of the modified human factors tools of function allocation, operational sequence diagram and needs assessment. These tools allow for adaptability and ease of understanding in the design or renovation of exhibits.

  20. Bringing dinosaurs back to life: exhibiting prehistory at the American Museum of Natural History.

    Science.gov (United States)

    Rieppel, Lukas

    2012-09-01

    This essay examines the exhibition of dinosaurs at the American Museum of Natural History during the first two decades of the twentieth century. Dinosaurs provide an especially illuminating lens through which to view the history of museum display practices for two reasons: they made for remarkably spectacular exhibits; and they rested on contested theories about the anatomy, life history, and behavior of long-extinct animals to which curators had no direct observational access. The American Museum sought to capitalize on the popularity of dinosaurs while mitigating the risks of mounting an overtly speculative display by fashioning them into a kind of mixed-media installation made of several elements, including fossilized bone, shellac, iron, and plaster. The resulting sculptures provided visitors with a vivid and lifelike imaginative experience. At the same time, curators, who were anxious to downplay the speculative nature of mounted dinosaurs, drew systematic attention to the material connection that tied individual pieces of fossilized bone to the actual past. Freestanding dinosaurs can therefore be read to have functioned as iconic sculptures that self-consciously advertised their indexical content.

  5. Walk, Look, Remember: The Influence of the Gallery's Spatial Layout on Human Memory for an Art Exhibition.

    Science.gov (United States)

    Krukar, Jakub

    2014-09-01

    The spatial organisation of museums and its influence on the visitor experience has been the subject of numerous studies. Previous research, despite reporting some actual behavioural correlates, rarely had the possibility to investigate the cognitive processes of the art viewers. In the museum context, where spatial layout is one of the most powerful curatorial tools available, attention and memory can be measured as a means of establishing whether or not the gallery fulfils its function as a space for contemplating art. In this exploratory experiment, 32 participants split into two groups explored an experimental, non-public exhibition and completed two unanticipated memory tests afterwards. The results show that some spatial characteristics of an exhibition can inhibit the recall of pictures and shift the focus to perceptual salience of the artworks.

  6. From Science to Action: Teaching and Talking about Climate Change in a Museum Exhibition

    Science.gov (United States)

    Barnes, H.

    2011-12-01

    The goal of Earth Revealed, a permanent exhibition at the Museum of Science and Industry (MSI) is to teach the science behind climate change by making the data accessible, personable, and relevant. In live science experiences guided by an MSI facilitator, guests discuss, vote, share knowledge, ideas, and action items that individuals can take to help reduce climate change. Through a partnership with the National Oceanic and Atmospheric Administration (NOAA), MSI receives the data sets and images that are projected onto a spherical display system. Using the Science on a Sphere, facilitators engage guests in a live participatory show up to five times a day to discuss climate change. Facilitators are trained to use inquiry based learning strategies and positive reinforcement engagement strategies. In the 20 minute live science experience, audience members participate and the facilitator is expected to tailor content according to the group's responses. The theme of Earth Revealed is climate change, and there are multiple stories that facilitators use to engage guests. Based on images from NOAA and through current science news research facilitators discuss content ranging from sea surface temperature to the earth's atmosphere. CO2 + You is the title of the longest running live science experience in Earth Revealed, and is dedicated to teaching how CO2 relates to climate change and how guests can reduce carbon dioxide emissions and thus help mitigate climate change. Participants in this session will learn a bit more in depth about the structure of MSI's Earth Revealed Live Science Experiences, and learn the teaching and participation strategies applied to increase guest participation, discussion, and learning. Session attendees will have an opportunity to participate in the inquiry process and explore various types of positive reinforcement strategies MSI facilitators are trained to implement.

  7. Light and Dark: a Mixed Mode Exhibition and Art Installation Project

    Walsh, R. W.

    2016-12-01

    From June to July 2016, the University of Central Lancashire, Preston, England delivered a Science and Technology Facilities Council funded exhibition and art installation project entitled `Exploring Light and Dark' in collaboration with the Beacon Museum, Whitehaven, Cumbria. Whitehaven is a small harbor town on the far west coast of Cumbria, England. With a population of about 24,000, it is located outside of the Lake District National Park. The major industry is the nearby Sellafield nuclear complex, with which a large proportion of the population has links. We showcased the work of some of our science teams in the areas of astrophysics, ecology and engineering. Visitors were able to experience new ways of learning about research through our audio visual exhibits including films, interpretation boards and hands-on activities. The center-piece was a 3.5m high semi-circular projection of the EUV images of the Sun obtained from NASA's Solar Dynamic Observatory. Specifically visitors explored the following questions: What's a Stellar Explosion? What do you know about the Sun, our closest star? Do you know what a Black Hole is? Why do certain worms react to White Night light conditions? What's a Light Echo? How are plasmas created? How are stars born? What do stone circles tell us about what our ancestors thought about the Sun, the moon and the stars? The programme of activities also included Storytelling (a local storyteller incorporated the folklore about the Sun with science research) and Choreography (a dance artist delivered interpretive dance workshops about the lifecycle of stars). Consequently, 2500 individuals visited the exhibition over the four-week period. A full evaluation of this exhibition is currently being undertaken and a summary of findings will be presented at this meeting. This will outline how this broad mix of scientists has critically reflected on the range of science communication techniques employed in "Light and Dark" with a view to sharing

  8. Testing the impact on natural risks' awareness of visual communication through an exhibition

    The need to communicate about natural disasters in order to improve the awareness of communities at risk is not a matter for debate anymore. However, communication can be implemented using different media and tools, and their effectiveness may be difficult to grasp. Current research on the topic is usually focused on assessing whether communication practices meet users' needs, whereas impact assessment is mostly left out. It can be explained by difficulties arising from (1) the definition of the impact to measure, i.e. awareness, and the appropriate indicators to measure it and its variations, and (2) the implementation of a research design that allows assessing these impacts without bias. This research aims at both developing a methodology to measure risk awareness and to use it for testing the effectiveness of visual communication. The testing was conducted in the Ubaye Valley in France, an alpine area affected by multiple hazards, from December 2013 to mid-February 2014. The setting consisted of an exhibition in the public library of the main town, Barcelonnette. The main natural hazards of the study case (i.e. landslides, avalanches, flooding, debris flows and earthquakes), as well as structural and non-structural measures were presented to the general public using local examples of hazards events and mitigation. Various visualization tools were used: videos, Google earth map, interactive timeline, objects, mock-ups, technical devices as well as posters with pictures, drawings and graphs. In order to assess the effects of the exhibition on risk awareness, several groups of children and adults were submitted to a research design, consisting of 1) a pre-test, 2) the visit of the exhibition and 3) a post-test similar to the pre-test. Close-ended questions addressed the awareness indicators according to the literature, i.e. worry level, previous experiences with natural hazards events, exposure to awareness raising, ability to mitigate/respond/prepare, attitude to

  10. The reef-building coral Siderastrea siderea exhibits parabolic responses to ocean acidification and warming.

    2014-12-22

    Anthropogenic increases in atmospheric CO2 over this century are predicted to cause global average surface ocean pH to decline by 0.1-0.3 pH units and sea surface temperature to increase by 1-4°C. We conducted controlled laboratory experiments to investigate the impacts of CO2-induced ocean acidification (pCO2 = 324, 477, 604, 2553 µatm) and warming (25, 28, 32°C) on the calcification rate of the zooxanthellate scleractinian coral Siderastrea siderea, a widespread, abundant and keystone reef-builder in the Caribbean Sea. We show that both acidification and warming cause a parabolic response in the calcification rate within this coral species. Moderate increases in pCO2 and warming, relative to near-present-day values, enhanced coral calcification, with calcification rates declining under the highest pCO2 and thermal conditions. Equivalent responses to acidification and warming were exhibited by colonies across reef zones and the parabolic nature of the corals' response to these stressors was evident across all three of the experiment's 30-day observational intervals. Furthermore, the warming projected by the Intergovernmental Panel on Climate Change for the end of the twenty-first century caused a fivefold decrease in the rate of coral calcification, while the acidification projected for the same interval had no statistically significant impact on the calcification rate-suggesting that ocean warming poses a more immediate threat than acidification for this important coral species.

  11. EXPO 2015 as a Laboratory for Neoliberalization. Great Exhibitions, Urban Value Dispossession and New Labor Relations

    Directory of Open Access Journals (Sweden)

    Emanuele Leonardi

    2016-09-01

    Full Text Available Great Exhibitions provide analytical lenses whereby capitalist development can be read from material as well as intangible perspectives. Thus, the paper approaches Milan EXPO 2015 through the grid of intelligibility provided by the concept of neoliberalism/neoliberalization, namely as a regulatory experi-ment. EXPO 2015 is first situated against the background of a growing body of literature which interprets mega-events as catalysts of territorial dispossession. Starting from the critical urban theory premise that neoliberalization is necessarily a spatial project, the features of urban space production set in motion by the World Fair are analyzed by paying particular attention to the ways in which social movements framed such transformations and eventually mobilized in reaction to them. Secondly, EXPO 2015 functioned as a laboratory for the implementation of unprecedented labor relations. In particular, the widespread re-course to voluntary or unpaid workforces is in connection with the shift from wage to human capital as the pillar of social mediation between productive subjects

  13. Human P-glycoprotein exhibits reduced affinity for substrates during a catalytic transition state.

    Ramachandra, M; Ambudkar, S V; Chen, D; Hrycyna, C A; Dey, S; Gottesman, M M; Pastan, I

    1998-04-01

    Human P-glycoprotein (Pgp), a plasma membrane protein that confers multidrug resistance, functions as an ATP-dependent drug efflux pump. Pgp contains two ATP binding/utilization sites and exhibits ATPase activity that is stimulated in the presence of substrates and modulating agents. The mechanism of coupling of ATP hydrolysis to drug transport is not known. To understand the role of ATP hydrolysis in drug binding, it is necessary to develop methods for purifying and reconstituting Pgp that retains properties including stimulation of ATPase activity by known substrates to an extent similar to that in the native membrane. In this study, (His)6-tagged Pgp was expressed in Trichoplusia ni (High Five) cells using the recombinant baculovirus system and purified by metal affinity chromatography. Upon reconstitution into phospholipid vesicles, purified Pgp exhibited specific binding to analogues of substrates and ATP in affinity labeling experiments and displayed a high level of drug-stimulated ATPase activity (specific activity ranging from 4.5 to 6.5 micromol min-1 mg-1). The ATPase activity was inhibited by ADP in a competitive manner, and by vanadate and N-ethylmaleimide at low concentrations. Vanadate which is known to inhibit ATPase activity by trapping MgADP at the catalytic site inhibited photoaffinity labeling of Pgp with substrate analogues, [125I]iodoarylazidoprazosin and [3H]azidopine, only under ATP hydrolysis conditions. Because vanadate-trapped Pgp is known to resemble the ADP and phosphate-bound catalytic transition state, our findings indicate that ATP hydrolysis results in a conformation with reduced affinity for substrates. A catalytic transition conformation with reduced affinity would essentially result in substrate dissociation and supports a model for drug transport in which an ATP hydrolysis-induced conformational change leads to drug release toward the extracellular medium.

  5. ‘Something simple and striking, if not amusing’ – the Freedom 7 special exhibition at the Science Museum, 1965

    Directory of Open Access Journals (Sweden)

    Dr Jean-Baptiste Gouyon

    2014-03-01

    Full Text Available From October 1965 to May 1966, the Science Museum in London displayed the American spacecraft Freedom 7, the first capsule in NASA’s Mercury programme to take a human on a suborbital flight. Archival records concerning this temporary display are extensive and contain photographic sources as well as written ones. This case therefore lends itself to a study aimed at evaluating the comparative merits of these two types of records, for understanding the logic at play in the display, and for retrieving at least part of the visitors’ experience. Visual sources emerge from this comparison as invaluable records for accessing the materiality of this temporary exhibition. They demonstrate that the Freedom 7 special exhibition was a key moment in the establishment of a space science and technology section at the Science Museum, as it enabled the Museum to begin historicising what was then a new field of scientific and technological enquiry. The exhibition follows a logic of display theorised in 1950 by Henry Calvert, a senior curator, in a note recently discovered in the Science Museum’s archives. It is based on the display of a star object that draws visitors’ attention towards less charismatic exhibits.

    2013-01-01

    In an effort to reach out to library users and make the library a more relevant, welcoming place, the University of Florida's Health Science Center Library hosted exhibits from the National Library of Medicine's (NLM) Traveling Exhibition Program. From 2010 through 2012, the library hosted four NLM exhibits and created event series for each. Through reflection and use of a participant survey, lessons were learned concerning creating relevant programs, marketing events, and forming new partnerships. Each successive exhibit added events and activities to address different audiences. A survey of libraries that have hosted NLM exhibits highlights lessons learned at those institutions.

  14. Innate immune defenses exhibit circadian rhythmicity and differential temporal sensitivity to a bacterial endotoxin in Nile tilapia (Oreochromis niloticus)

    DEFF Research Database (Denmark)

    Lazado, Carlo Cabacang; Skov, Peter Vilhelm; Pedersen, Per Bovbjerg

    2016-01-01

    exposed at ZT15. Taken together, this study shows that several key components of humoral immunity in tilapia exhibit circadian rhythms and adapt to photoperiodic changes. Further, results of the bacterial endotoxin challenge suggest that responsiveness of serum humoral factors to a biological insult......The present study investigated the daily dynamics of humoral immune defenses and the temporal influence in the sensitivity of these responses to a bacterial endotoxin in Nile tilapia (Oreochromis niloticus). The first experiment subjected the fish to two photoperiod conditions, 12L:12D (LD) and 0L......:24D (DD), for 20 days to characterize the rhythms of humoral immunity. Serum alkaline phosphatase (ALP), lysozyme (LYZ), peroxidase (PER) and protease (PRO) exhibited significant rhythmicity under LD but not in DD. No significant rhythms were observed in esterase (ESA) and anti-protease (ANTI...

  15. Cytochrome c1 exhibits two binding sites for cytochrome c in plants.

    Science.gov (United States)

    Moreno-Beltrán, Blas; Díaz-Quintana, Antonio; González-Arzola, Katiuska; Velázquez-Campoy, Adrián; De la Rosa, Miguel A; Díaz-Moreno, Irene

    2014-10-01

    In plants, channeling of cytochrome c molecules between complexes III and IV has been purported to shuttle electrons within the supercomplexes instead of carrying electrons by random diffusion across the intermembrane bulk phase. However, the mode plant cytochrome c behaves inside a supercomplex such as the respirasome, formed by complexes I, III and IV, remains obscure from a structural point of view. Here, we report ab-initio Brownian dynamics calculations and nuclear magnetic resonance-driven docking computations showing two binding sites for plant cytochrome c at the head soluble domain of plant cytochrome c1, namely a non-productive (or distal) site with a long heme-to-heme distance and a functional (or proximal) site with the two heme groups close enough as to allow electron transfer. As inferred from isothermal titration calorimetry experiments, the two binding sites exhibit different equilibrium dissociation constants, for both reduced and oxidized species, that are all within the micromolar range, thus revealing the transient nature of such a respiratory complex. Although the docking of cytochrome c at the distal site occurs at the interface between cytochrome c1 and the Rieske subunit, it is fully compatible with the complex III structure. In our model, the extra distal site in complex III could indeed facilitate the functional cytochrome c channeling towards complex IV by building a "floating boat bridge" of cytochrome c molecules (between complexes III and IV) in plant respirasome.

  16. Energy distributions exhibited during thermal runaway of commercial lithium ion batteries used for human spaceflight applications

    Science.gov (United States)

    Yayathi, Sandeep; Walker, William; Doughty, Daniel; Ardebili, Haleh

    2016-10-01

    Lithium ion (Li-ion) batteries provide low mass and energy dense solutions necessary for space exploration, but thermal related safety concerns impede the utilization of Li-ion technology for human applications. Experimental characterization of thermal runaway energy release with accelerated rate calorimetry supports safer thermal management systems. 'Standard' accelerated rate calorimetry setup provides means to measure the addition of energy exhibited through the body of a Li-ion cell. This study considers the total energy generated during thermal runaway as distributions between cell body and hot gases via inclusion of a unique secondary enclosure inside the calorimeter; this closed system not only contains the cell body and gaseous species, but also captures energy release associated with rapid heat transfer to the system unobserved by measurements taken on the cell body. Experiments include Boston Power Swing 5300, Samsung 18650-26F and MoliCel 18650-J Li-ion cells at varied states-of-charge. An inverse relationship between state-of-charge and onset temperature is observed. Energy contained in the cell body and gaseous species are successfully characterized; gaseous energy is minimal. Significant additional energy is measured with the heating of the secondary enclosure. Improved calorimeter apparatus including a secondary enclosure provides essential capability to measuring total energy release distributions during thermal runaway.

  17. Soil factors exhibit greater influence than bacterial inoculation on alfalfa growth and nitrogen fixation.

    Science.gov (United States)

    Neumann, Ute; Kosier, Bob; Jahnke, Joachim; Priefer, Ursula B; Al-Halbouni, Djamila

    2011-09-01

    In order to study the effects of soil factors and bacterial inoculation on alfalfa (Medicago sativa), plants were inoculated with Ensifer meliloti L33 and Azospirillum brasilense Sp7 in pot experiments using two different soils separately as well as in a mixture. One soil was contaminated with chemical waste products; the other was an arable soil. Soil factors, including the availability of macro- and micronutrients as well as carbon and nitrogen contents, were found to exhibit a much greater influence on the growth of alfalfa than any of the inoculations. In contaminated soil, the shoot and root growth of alfalfa was decreased and nodules were diminished and ineffective. Bacterial inoculations did not significantly improve this hostile growth environment. However, in a mixture (44% arable, 22% contaminated soil, 34% vermiculite), growth conditions for alfalfa were improved so that shoot dry weight and nodule numbers increased up to 100- and 20-fold, respectively, compared with the contaminated soil. For the strain L33, its persistence in the rhizosphere was correlated to the presence of its host plant, but its dynamics were influenced by competition with indigenous rhizobia. The strain Sp7, once provided with a suitable soil, was not dependent on the plant's rhizosphere, but it enhanced the performance of L33 and native rhizobia.

  18. Papain-templated Cu nanoclusters: assaying and exhibiting dramatic antibacterial activity cooperating with H₂O₂.

    Science.gov (United States)

    Miao, Hong; Zhong, Dan; Zhou, Zinan; Yang, Xiaoming

    2015-12-07

    Herein, papain-functionalized Cu nanoclusters (CuNCs@Papain) were originally synthesized in aqueous solution together with a quantum yield of 14.3%, and showed obviously red fluorescence at 620 nm. Meanwhile, their corresponding fluorescence mechanism was fully elucidated by fluorescence spectroscopy, HR-TEM, FTIR spectroscopy, and XPS. Subsequently, the as-prepared CuNCs were employed as probes for detecting H2O2. Using CuNCs as probes, H2O2 was determined in the range from 1 μM to 50 μM based on a linear decrease of fluorescence intensity as well as a detection limit of 0.2 μM with a signal-to-noise ratio of 3. More significantly, it has been proved that CuNCs could convert H2O2 to ˙OH, which exhibited dramatic antibacterial activity. Both in vitro and in vivo experiments were performed to validate their antibacterial activity against Gram-positive/negative bacteria and actual wound infection, suggesting their potential for serving as one type of promising antibacterial material.

    Pyramidal neurons in layers 2/3 and 5 of primary somatosensory cortex (S1) exhibit somewhat modest synaptic plasticity after whisker input deprivation. Whether neurons involved at earlier steps of sensory processing show more or less plasticity has not yet been examined. Here, we used longitudinal in vivo two-photon microscopy to investigate dendritic spine dynamics in apical tufts of GFP-expressing layer 4 (L4) pyramidal neurons of the vibrissal (barrel) S1 after unilateral whisker trimming. First, we characterize the molecular, anatomical, and electrophysiological properties of identified L4 neurons in Ebf2-Cre transgenic mice. Next, we show that input deprivation results in a substantial (∼50%) increase in the rate of dendritic spine loss, acutely (4-8 d) after whisker trimming. This robust synaptic plasticity in L4 suggests that primary thalamic recipient pyramidal neurons in S1 may be particularly sensitive to changes in sensory experience. Ebf2-Cre mice thus provide a useful tool for future assessment of initial steps of sensory processing in S1.

    With prominent photocatalytic applications and widespread use in semiconductor devices, TiO2 is one of the most popular metal oxides. However, despite its popularity, it has yet to achieve its full potential due to a lack of effective methods for achieving p-type conductivity. Here, we show that undoped p-type TiO2 films can be fabricated by atomic layer deposition (ALD) and that their electrical properties can be controlled across a wide range using proper postprocessing anneals in various ambient environments. Hole mobilities larger than 400 cm(2)/(V·s) are accessible superseding the use of extrinsic doping, which generally produces orders of magnitude smaller values. Through a combination of analyses and experiments, we provide evidence that this behavior is primarily due to an excess of oxygen in the films. This discovery enables entirely new categories of TiO2 devices and applications, and unlocks the potential to improve existing ones. TiO2 homojunction diodes fabricated completely by ALD are developed as a demonstration of the utility of these techniques and shown to exhibit useful rectifying characteristics even with minimal processing refinement.

    Learners frequently need to access increasingly complex information to help them understand our changing world. More and more libraries are transforming themselves into places where learners not only access STEM information, but interact with professionals and undertake hands-on learning. Libraries are beginning to position themselves as part of learning ecosystems that contribute to a collective impact on the community. Traveling STEM exhibits are catalyzing these partnerships and engaging students, families, and adults in repeat visits through an accessible venue: their public library. The impact of the STAR Library Education Network's (STAR_Net) Discover Earth: A Century of Change exhibit on partnerships, the circulation of STEM resources, and the engagement of learners was studied by an external evaluation team. The STAR_Net project's summative evaluation utilized mixed methods to investigate project implementation and its outcomes. Methods included pre- and post-exhibit surveys administered to staff from each library that hosted the exhibits; interviews with staff from host libraries; patron surveys; exhibit-related circulation records; web metrics regarding the online STAR_Net community of practice; and site visits. A subset of host libraries recruited professionals, who delivered programming that connected Earth systems science, weather, climate, and conservation themes from the exhibit to local issues. Library patrons improved their knowledge about STEM topics presented in the exhibits and associated programming, and patrons viewing the exhibit reflected the demographics of their communities. In a follow-up survey, patrons reported spending an average of 60 minutes looking at the exhibit over their cumulative visits to the library. In contrast, visitors might visit a museum only once to look at a comparably-sized traveling exhibit due to barriers such as cost and distance. Exhibit host libraries reported an increase in the circulation of Earth science

  16. Low-loss multilayered metamaterial exhibiting a negative index of refraction at visible wavelengths

    Garcia-Meca, Carlos

    2012-02-01

    Over the last decade, metamaterials have attracted a great interest thanks to their potential to expand the range of electromagnetic properties found in natural materials. In particular, the possibility of achieving negative refractive index media (NIM) enables us to implement superlenses and optical storing devices. Since the first experimental demonstration at microwave frequencies, much effort has been put in extending negative refraction to the visible spectrum, where we can take full advantage of NIM properties. For instance, the superior imaging ability of NIM would be essential for visible microscopy. The desired features for NIM are low loss and isotropy. This last property includes polarization independence and negative-index behavior in all spatial directions. None of these features have been attained in previous experiments. Thus, the current challenge is to improve such aspects in order to make NIM suitable for practical applications. In this work, we experimentally demonstrate a low-loss multilayer metamaterial exhibiting a double-negative index in the visible spectrum, while presenting polarization independence at normal incidence. This has been achieved by exploiting the properties of a second-order magnetic resonance of the so-called fishnet structure, in contrast to previous works that used first-order magnetic resonances, both related to gap surface plasmon polariton (SPP) modes. The low-loss nature of the employed magnetic resonance, together with the effect of the interacting adjacent layers, results in a figure of merit as high as 3.34. A wide spectral range of negative index is achieved, covering the wavelength region between 620 and 806 nm with only two different designs. The fabricated metamaterials are the first experimental multilayer NIM in the visible spectrum, which entails an important step towards homogeneous NIM in this range. Finally, we found that the SPP modes determining the permeability resonance display weak angular dispersion.

    Full Text Available Gandhiji, a socio-political figure, struggled for the sake of India’s development and independence. He is an immense source of writing and has influenced different disciplines and many writers from different fields like history, politics, philosophy, literature, sociology, and so on. He served as a central figure for their writings. Gandhiji not only struggled for India’s independence but also taught the people of India to love one another and advised them to show bitterness towards non-violence. In this principle of non-violence Gandhiji introduces technique of resistance to evil and untruth. His Satyagraha is inspired by boundless love and compassion. It is opposed to sin and evil. Gandhiji was the speaker of truth and he does not like falsehood. These principles of Gandhiji were very well exhibited in the novels of R.K. Narayan. One or in another way the characters of the novels explore Gandhiji himself or his views. For example, in a novel called Waiting for Mahatma Gandhiji, himself has participated as a character. Bharati an important personality in the novel serves as a disciple of Gandhiji. The famous novels of R.K. Narayan were Swami and Friends (1935, The Bachelor of Arts (1937, The English Teacher (1945, Waiting for Mahatma (1955, The Vendor of Sweets (1967 were all set in Narayan’s imaginary town, Malgudi. It is not a place but an experience of soil and soul of India. The paper aims at analysing the novels of R.K. Narayan on this backdrop and it concludes that his novels serve as a panorama for the future generation, to know Gandhi as a whole.

  18. Yersinia pestis intracellular parasitism of macrophages from hosts exhibiting high and low severity of plague.

    Directory of Open Access Journals (Sweden)

    Duraisamy Ponnusamy

    Full Text Available BACKGROUND: Yersinia pestis causes severe disease in natural rodent hosts, but mild to inapparent disease in certain rodent predators such as dogs. Y. pestis initiates infection in susceptible hosts by parasitizing and multiplying intracellularly in local macrophages prior to systemic dissemination. Thus, we hypothesize that Y. pestis disease severity may depend on the degree to which intracellular Y. pestis overcomes the initial host macrophage imposed stress. METHODOLOGY/PRINCIPAL FINDINGS: To test this hypothesis, the progression of in vitro infection by Y. pestis KIM62053.1+ of mouse splenic and RAW264.7 tissue culture macrophages and dog peripheral blood-derived and DH82 tissue culture macrophages was studied using microscopy and various parameters of infection. The study showed that during the early stage of infection, intracellular Y. pestis assumed filamentous cellular morphology with multiple copies of the genome per bacterium in both mouse and dog macrophages. Later, in mouse macrophages, the infection elicited spacious vacuolar extension of Yersinia containing vacuoles (YCV, and the filamentous Y. pestis reverted to coccobacillary morphology with genomic equivalents approximately equaling colony forming units. In contrast, Y. pestis infected dog macrophages did not show noticeable extension of YCV, and intracellular Y. pestis retained the filamentous cellular morphology for the entire experiment in DH82 cells or were killed by blood-derived macrophages. In addition, during the later stage of infection, Y. pestis infected mouse macrophages exhibited cell lysis whereas dog macrophages did not. CONCLUSION/SIGNIFICANCE: Overall, these results support our hypothesis that Y. pestis in mouse macrophages can overcome the initial intracellular stress necessary for subsequent systemic infection. However, in dogs, failure of Y. pestis to overcome macrophage imposed stress may result in mild or in apparent disease in dogs.
