    The α-particle light response of liquid scintillators based on linear alkylbenzene (LAB) has been measured with three different experimental approaches. In the first approach, α-particles were produced in the scintillator via {sup 12}C(n,α){sup 9}Be reactions. In the second approach, the scintillator was loaded with 2 % of {sup nat}Sm providing an α-emitter, {sup 147}Sm, as an internal source. In the third approach, a scintillator flask was deployed into the water-filled SNO+ detector and the radioactive contaminants {sup 222}Rn, {sup 218}Po and {sup 214}Po provided the α-particle signal. The behavior of the observed α-particle light outputs are in agreement with each case successfully described by Birks' law. The resulting Birks parameter kB ranges from (0.0066 ± 0.0016) to (0.0076 ± 0.0003) cm/MeV. In the first approach, the α-particle light response was measured simultaneously with the light response of recoil protons produced via neutron- proton elastic scattering. This enabled a first time a direct comparison of kB describing the proton and the α-particle response of LAB based scintillator. The observed kB values describing the two light response functions deviate by more than 5σ. The presented results are valuable for all current and future detectors, using LAB based scintillator as target, since they depend on an accurate knowledge of the scintillator response to different particles.

    Manipulation of microscale particles and fluid liquid droplets is an important task for lab-on-a-chip devices for numerous biological researches and applications, such as cell detection and tissue engineering. Particle manipulation techniques based on surface acoustic waves (SAWs) appear effective for lab-on-a-chip devices because they are non-invasive, compatible with soft lithography micromachining, have high energy density, and work for nearly any type of microscale particles. Here we review the most recent research and development of the past two years in SAW based particle and liquid droplet manipulation for lab-on-a-chip devices including particle focusing and separation, particle alignment and patterning, particle directing, and liquid droplet delivery.

    The demand for easy to use and cost effective medical technologies inspires scientists to develop innovative lab-on-chip technologies for point-of-care in vitro diagnostic testing. To fulfill medical needs, the tests should be rapid, sensitive, quantitative, and miniaturizable, and need to integrate all steps from sample-in to result-out. Here, we review the use of magnetic particles actuated by magnetic fields to perform the different process steps that are required for integrated lab-on-chip diagnostic assays. We discuss the use of magnetic particles to mix fluids, to capture specific analytes, to concentrate analytes, to transfer analytes from one solution to another, to label analytes, to perform stringency and washing steps, and to probe biophysical properties of the analytes, distinguishing methodologies with fluid flow and without fluid flow (stationary microfluidics). Our review focuses on efforts to combine and integrate different magnetically actuated assay steps, with the vision that it will become possible in the future to realize integrated lab-on-chip biosensing assays in which all assay process steps are controlled and optimized by magnetic forces.

    We present an overview of the modelling of particle number concentrations (PNCs) in five major European cities, namely Helsinki, Oslo, London, Rotterdam, and Athens, in 2008. Novel emission inventories of particle numbers have been compiled both on urban and European scales. We used atmospheric dispersion modelling for PNCs in the five target cities and on a European scale, and evaluated the predicted results against available measured concentrations. In all the target cities, the concentrations of particle numbers (PNs) were mostly influenced by the emissions originating from local vehicular traffic. The influence of shipping and harbours was also significant for Helsinki, Oslo, Rotterdam, and Athens, but not for London. The influence of the aviation emissions in Athens was also notable. The regional background concentrations were clearly lower than the contributions originating from urban sources in Helsinki, Oslo, and Athens. The regional background was also lower than urban contributions in traffic environments in London, but higher or approximately equal to urban contributions in Rotterdam. It was numerically evaluated that the influence of coagulation and dry deposition on the predicted PNCs was substantial for the urban background in Oslo. The predicted and measured annual average PNCs in four cities agreed within approximately ≤ 26 % (measured as fractional biases), except for one traffic station in London. This study indicates that it is feasible to model PNCs in major cities within a reasonable accuracy, although major challenges remain in the evaluation of both the emissions and atmospheric transformation of PNCs.

    Results are presented from particle flux studies using sediment trap and current meter moorings along a transect at the European continental margin at 49 degrees N within the Ocean Margin Exchange (OMEX) project. Two moorings were placed, at the mid- and outer slope in water depths of 1500 and 3660 m, with traps at 600 and 1050 m and at 580, 1440 and 3220 m, respectively. Residual currents at the mid- slope follow the slope contour, whereas seasonal off-slope flow was registered at the outer slope. At 600 m on the slope fluxes are similar to those in the abyssal North Atlantic. The flux of all components (bulk dry weight, particulate organic and inorganic carbon, lithogenic matter and opal) increased with water depth. Highest fluxes were recorded at 1440 m at the outer slope, where off- slope residual currents mediate particle export. The injection of biogenic and lithogenic particles below the depth of winter mixing results in the export of particles from shallower waters. Calculated lateral fluxes of partic...

  16. Particle transport in pellet fueled JET (Jet European Torus) plasmas

    Baylor, L.R.

    1990-01-01

    Pellet fueling experiments have been carried out on the Joint European Torus (JET) tokamak with a multi-pellet injector. The pellets are injected at speeds approaching 1400 m/s and penetrate deep into the JET plasma. Highly peaked electron density profiles are achieved when penetration of the pellets approaches or goes beyond the magnetic axis, and these peaked profiles persist for more than two seconds in ohmic discharges and over one second in ICRF heated discharges. In this dissertation, analysis of electron particle transport in multi-pellet fueled JET limiter plasmas under a variety of heating conditions is described. The analysis is carried out with a one and one-half dimensional radial particle transport code to model the experimental density evolution with various particle transport coefficients. These analyses are carried out in plasmas with ohmic heating, ICRF heating, and neural beam heating, in limiter configurations. Peaked density profile cases are generally characterized by diffusion coefficients with a central (r/a < 0.5) diffusivity {approximately}0.1 m{sup 2}/s that increases rapidly to {approximately}0.3 m{sup 2}/s at r/a = 0.6 and then increases out to the plasma edge as (r/a){sup 2}. These discharges can be satisfactorily modeled without any anomalous convective (pinch) flux. 79 refs., 60 figs.

  17. Effect of Porosity on Particle Erosion Wear Behavior of Lab. Scale SICF/SIC Composites

    Science.gov (United States)

    Suh, Min-Soo; Kohyama, Akira

    The use of silicon-based ceramics and composites as combustor liners and turbine vanes provides the potential of improving next-generation turbine engine performance, through lower emissions and higher cycle efficiency, relative to today's use of super alloy hot-section components. As a series of research for FOD resistant, a particle erosion wear test was carried out for continuous Pre-SiC fiber-reinforced SiC matrix composites with a new concept of lab. scale fabrication by LPS process. The result shows that aperture (some form of porosity) between fiber and interface has a deleterious effect on erosion resistance. Aperture along the fiber interfaces consequently causes a severe wear in the form of fiber detachment. Wear rate increase proportional as contents of open porosity increases. For nearly full dense composite materials of about 0.5 % porosity, are about 200 % more wear-resistant than about 5 % porous composites. Grain growth and consolidate condition of matrix which directly affects to FOD resistant are also discussed.

    The coordinates of CIE L*a*b* uniform colour space have been acquired from the transmitance spectra of colour reference solutions of European Pharmacopoeia (Ph.Eur.). Calculation of colour differences of these solutions from purified water deltaE* gave their values in the range between 0.7 (B9 solution) to 36 (Y1 solution) CIE units. Excluding red colour reference soulutions, deltaE* values did not depend on concentrations of colour compounds linearly. Small deltaE* values founded by the brown and brownish-yellow colour reference solutions of the lowest concentrations can possibly cause some problems of visual examination of the degree of coloration of liquids according to Ph.Eur.

    Nano-silver particles were synthesized through chemical reduction method, using silver nitrate, m-dihydroxybenzene and polyvinylpyrrolidone as silver source, reduction agent and protective agent respectively; and redundant reactants were removed through centrifugation and washing operation. Then different nano-silver colloids were acquired by dispersing the nano-silver particles in water, ethanol and ethylene glycol respectively through ultrasonic dispersion. For comparison, the nano-silver particles mass fraction of all the colloids was 0.2 Wt% during the research. Nano-silver particles were characterized by laser particle size analyzer, transmission electron microscopy (TEM) and scanning electron microscopy (SEM); and the concentration of nano-silver colloids was confirmed through synchronized thermal analyzer (STA). The size distribution result of laser particle size analyzer showed that nano-silver particles were about 100 nm and had uniform size distribution. The images of TEM and SEM showed that the size of nano-silver particles was in nanoscale as well. To evaluate the dispersion stabilities of different nano-silver colloids, Turbiscan optical analyzer which was based on multiple light scattering analysis had been employed in the research; and the principle factors leading to instabilities of nano-silver colloids were also discussed. Results showed that particle size variation and particle migration were major factors which affected the dispersion stabilities of nano-silver colloids. For the nano-silver colloid dispersed in water phase, the backscattering light signal in middle of the sample cell stayed unchanged with time while the backscattering light signals at top and bottom of the sample cell showed dramatic variation during the measurement, which indicated that particle migration was the main reason why the nano-silver colloids was unstable. But for the nano-silver colloids dispersed in ethanol and ethylene glycol phase, the backscattering light

    Full Text Available Abstract Background To establish a common database on particle therapy for the evaluation of clinical studies integrating a large variety of voluminous datasets, different documentation styles, and various information systems, especially in the field of radiation oncology. Methods We developed a web-based documentation system for transnational and multicenter clinical studies in particle therapy. 560 patients have been treated from November 2009 to September 2011. Protons, carbon ions or a combination of both, as well as a combination with photons were applied. To date, 12 studies have been initiated and more are in preparation. Results It is possible to immediately access all patient information and exchange, store, process, and visualize text data, any DICOM images and multimedia data. Accessing the system and submitting clinical data is possible for internal and external users. Integrated into the hospital environment, data is imported both manually and automatically. Security and privacy protection as well as data validation and verification are ensured. Studies can be designed to fit individual needs. Conclusions The described database provides a basis for documentation of large patient groups with specific and specialized questions to be answered. Having recently begun electronic documentation, it has become apparent that the benefits lie in the user-friendly and timely workflow for documentation. The ultimate goal is a simplification of research work, better study analyses quality and eventually, the improvement of treatment concepts by evaluating the effectiveness of particle therapy.

    Epidemiological studies of long-term air pollution effects have been hampered by difficulties in characterizing the spatial variation in air pollution. We conducted a study to assess the risk of long-term exposure to traffic-related air pollution for the development of inhalant allergy and asthma in children in Stockholm county, Munich and the Netherlands. Exposure to traffic-related air pollution was assessed through a 1-year monitoring program and regression modeling using exposure indicators. This paper documents the performance of the exposure monitoring strategy and the spatial variation of ambient particle concentrations. We measured the ambient concentration of PM2.5 and the reflectance of PM2.5 filters ('soot') at 40-42 sites representative of different exposure conditions of the three study populations. Each site was measured during four 14-day average sampling periods spread over one year (spring 1999 to summer 2000). In each study area, a continuous measurement site was operated to remove potential bias due to temporal variation. The selected approach was an efficient method to characterize spatial differences in annual average concentration between a large number of sites in each study area. Adjustment with data from the continuous measurement site improved the precision of the calculated annual averages, especially for PM2.5. Annual average PM2.5 concentrations ranged from 11 to 20 μg/m 3 in Munich, from 8 to 16 μg/m 3 in Stockholm and from 14 to 26 μg/m 3 in the Netherlands. Larger spatial contrasts were found for the absorption coefficient of PM2.5. PM2.5 concentrations were on average 17-18% higher at traffic sites than at urban background sites, but PM2.5 absorption coefficients at traffic sites were between 31% and 55% increased above background. This suggests that spatial variation of traffic-related air pollution may be underestimated if PM2.5 only is measured.

Since it is believed that the traditional teaching methods often fail to foster positive attitudes towards learning science, the European Commission has made intensive efforts to promote science education in schools though new methods based on the inquiry methodology of learning: questions, search and answers. This should be coupled to laboratories and hands-on experience which should be structured and scaffolded in a pedagogically meaningful way. "PATHWAY", "Discover the COSMOS" and "ISE" have been providing the lesson plans and the best practices for teachers and students and "Go-lab" is working towards an integrated set up of on-line labs for large scale use in science education. In the next sections some concrete examples which aim to bring the High Energy Physics (HEP) frontier research to schools will be given.

  12. A Word from the DG: Preparing the strategy for European particle physics

    CERN Multimedia

    2006-01-01

    Particle physics is an increasingly globalized field, with the LHC marking the turning point from regional to world-wide organization. Although still a European-led project, the LHC is the first accelerator that CERN has built with help from non-Member States, and its experiments are the most international collaboration that particle physics has ever known. For Europe to engage in this process of globalization for future projects, and to maintain a leading position in the field, we need a European strategy. The European Commission is considering introducing basic research in possible actions during its R&D framework programme (2007-2013). It is with this in mind that the CERN Council established a strategy group in 2005. The group was asked to define and prioritize technical options in preparing a long-term vision for European particle physics for presentation to Council at a special meeting in Lisbon on 14 July this year. CERN Council's decision to establish the strategy group recognizes the distinctio...

    Many students do not recognize that individual organisms within populations vary, and this may make it difficult for them to recognize the essential role variation plays in natural selection. Also, many students have weak scientific reasoning skills, and this makes it difficult for them to recognize misconceptions they might have. This paper describes a 2-h laboratory for college students that introduces them to genetic diversity and gives them practice using hypothetico-deductive reasoning. In brief, the lab presents students with DNA sequences from Africans, Europeans, and Asians, and asks students to determine whether people from each continent qualify as distinct "races." Comparison of the DNA sequences shows that people on each continent are not more similar to one another than to people on other continents, and therefore do not qualify as distinct races. Ninety-four percent of our students reported that the laboratory was interesting, and 79% reported that it was a valuable learning experience. We developed and used a survey to measure the extent to which students recognized variation and its significance within populations and showed that the lab increased student awareness of variation. We also showed that the lab improved the ability of students to construct hypothetico-deductive arguments.

  15. A word from the DG: The European strategy for particle physics

    2006-01-01

    The CERN Council took the bold and important decision of unanimously approving a European strategy for particle physics at a dedicated meeting held in Lisbon on 14 July. The consequences for particle physics and for this Laboratory are profound. The full strategy statement is available through the CERN Council web pages at the address http://www.cern.ch/council-strategygroup, but I would like to underline some of the key points here. In endorsing the strategy, the Council has agreed to act as a council for European particle physics, and not only as a council for CERN. The Council has accepted the considerable responsibility of defining and updating Europe's strategy for particle physics, and of representing Europe on the world stage. The general issues of the strategy recognize Europe's strength and depth in the field, at strong national institutes, at universities and laboratories, and at CERN. The scientific issues place the LHC firmly on top of the list, both in terms of its initial exploitation and possi...

    The number of ultrafine particles in urban air may be more health relevant than the usually measured mass of particles smaller than 2.5 or 10 mm. Epidemiological studies typically assess exposure by measurements at a central site. Limited information is available about how well measurements at a central site reflect exposure to ultrafine particles. The goals of this paper are to assess the relationships between particle number (PN) and mass concentrations measured outdoors at a central site, right outside and inside the study homes. The study was conducted in four European cities: Amsterdam, Athens, Birmingham and Helsinki. Particle mass (PM10 and PM2.5), PN, soot and sulfate concentrations were measured at these sites. Measurements of indoors and outdoors near the home were made during 1 week in 152, mostly non-smoking, homes. In each city continuous measurements were also performed at a central site during the entire study period. The correlation between 24-h average central site outdoor and indoor concentrations was lower for PN (correlation among cities ranged from 0.18 to 0.45) than for PM2.5 (0.40-0.80), soot (0.64-0.92) and sulfate (0.91-0.99). In Athens, the indoor-central site correlation was similar for PN and PM2.5. Infiltration factors for PN and PM2.5 were lower than for sulfate and soot. Night-time hourly average PN concentrations showed higher correlations between indoor and central site, implying that indoor sources explained part of the low correlation found for 24-h average concentrations. Measurements at a central site may characterize indoor exposure to ambient particles less well for ultrafine particles than for fine particle mass, soot and sulfate.

  17. Bacterial composition and survival on Sahara dust particles transported to the European Alps

    Full Text Available Deposition of Sahara dust (SD particles is a frequent phenomenon in Europe, but little is known about the viability and composition of the bacterial community transported with SD. The goal of this study was to characterize SD-associated bacteria transported to the European Alps, deposited and entrapped in snow. During two distinct events in February and May 2014, SD particles were deposited and promptly covered by falling snow, thus preserving them in distinct ochre layers within the snowpack. In June 2014, we collected samples at different depths from a snow profile at the Jungfraujoch (Swiss Alps; 3621 m a.s.l.. After filtration, we performed various microbiological and physicochemical analyses of the snow and dust particles therein that originated in Algeria.Our results show that bacteria survive and are metabolically active after the transport to the European Alps. Using high throughput sequencing, we observed distinct differences in bacterial community composition and structure in SD-layers as compared to clean snow layers. Sporulating bacteria were not enriched in the SD-layers; however, phyla with low abundance such as Gemmatimonadetes and Deinococcus-Thermus appeared to be specific bio-indicators for SD. Since many members of these phyla are known to be adapted to arid oligotrophic environments and UV radiation, they are well suited to survive the harsh conditions of long-range airborne transport.

    DUBLIN, Ireland -- CERN, the famed Swiss high-energy particle physics lab, has a problem. It's about to start generating more data than any computer or network anywhere in the world is able to analyze. That prospect has led CERN to drive a major European project to create a vast "grid" research network of computers across Europe. When completed, the 10 million euro, Linux-based endeavor called DataGRID, will become a principal European computing resource for researchers of many disciplines. "I believe grid computing will revolutionize the way we compute, in much the same way as the World Wide Web and Internet changed the way we communicate," said John Ellis, a theoretical physicist and adviser to the director general of CERN.

    The Clinical Chemistry Analyzer Dimension 380 manufactured by Du Pont de Nemours was tested in a multicentre evaluation according to the guide-lines of the European Committee for Clinical Laboratory Standards (ECCLS) and in part to the protocol of the Société Française de Biologie Clinique (SFBC). The instrument and the reagents were evaluated as a system, since both reagents and reagent cartridges are specifically designed for the instrument. Fourteen analytes including electrolytes, substrates and enzymes were tested. The evaluators summarized their experience as follows: 1. All parameters tested yield results comparable to established procedures. 2. Very good performance of the ion-selective-electrode unit. 3. The imprecision data of the system are, for most parameters, between 1 and 4% CV and thus equal to or better than those of the instruments compared. 4. No reagent or sample carry-over was detected after a minor modification of the instrument. 5. The linearity of Dimension test methods in general covers the range stated by the manufacturer. 6. Very good stability of the calibration curves (up to 2 months). 7. Good practicability of the whole system, including handling of reagents and a very user-friendly software.

    In the present study, a method was developed for detection of Vibrio parahaemolyticus based on a stationary liquid phase lab-on-a-chip (SLP LOC). The present SLP LOC comprises a sample chamber, washing chamber, and detection chamber connected by two channels. The method utilizes two types of particles: capture particles (CPs), which are magnetic nanoparticles functionalized with antibody; and labeling particles (LPs), which are silica nanoparticles functionalized with horseradish peroxidase and antibody. Samples were added to the sample chamber with CPs and LPs, forming a CP-bacteria-LP complex, and the complex was transported to the detection chamber containing chromogenic substrate solution. The method allowed the detection of V. parahaemolyticus in the range of 10 1 -10 5 cfu within 45min. Additionally, contamination of oyster samples with V. parahaemolyticus was detected within 2.5h, including 2h of culturing. The present method has the advantage of being highly rapid and facile, and enabling the detection of bacteria with high sensitivity. Moreover, the LOC and LOC processing device used in this method possess simple structures, making the detection process economical and allowing miniaturization. Therefore, the present SLP LOC detection method is potentially useful for in situ determination of food safety. Copyright © 2016 Elsevier B.V. All rights reserved.

    Magnetic beads (MBs) with ∼1.9 μm average diameter were used to transport specific microliter-scale volumes of liquids between adjacent reservoirs within a closed tube under the influence of a magnetic field. The tube's inner surface is coated with a hydrophobic layer, enabling the formation of a surface tension valve by inserting an air gap between reservoirs. This transfer process was implemented by keeping the MBs stationary with a fixed external magnet while the liquid reservoirs were translated by a computer-controlled syringe pump system. The magnet induces the aggregation of MBs in a loosely packed cluster (void volume ∼90-95%) against the tube's inner wall. The liquid trapped in the MB cluster is transported across the air gap between reservoirs. Fluorescence intensity from a dye placed in one reservoir is used to measure the volume of liquid transferred between reservoirs. The carry-over liquid volume is controlled by the mass of the MBs within the device. The typical volume of liquid carried by the MB cluster is ∼2 to 3 μL/mg of beads, allowing the use of small samples. This technique can be used to study the effect of small compositional variation on the properties of fluid mixtures. The feasibility of this "lab-in-tube" approach for binary phase diagram determination in a water-surfactant (C12E5) system was demonstrated.

    In the world of computer-based data acquisition and control, the graphical interface program LabVIEW from National Instruments is so ubiquitous that in many ways it has almost become the laboratory standard. To date, there have been approximately fifteen books concerning LabVIEW, but Professor Essick's treatise takes on a completely different tack than all of the previous discussions. In the more standard treatments of the ways and wherefores of LabVIEW such as LabVIEW Graphical Programming: Practical Applications in Instrumentation and Control by Gary W. Johnson (McGraw Hill, NY 1997), the emphasis has been instructing the reader how to program LabVIEW to create a Virtual Instrument (VI) on the computer for interfacing to a particular instruments. LabVIEW is written in G a graphical programming language developed by National Instruments. In the past the emphasis has been on training the experimenter to learn G . Without going into details here, G incorporates the usual loops, arithmetic expressions, etc., found in many programming languages, but in an icon (graphical) environment. The net result being that LabVIEW contains all of the standard methods needed for interfacing to instruments, data acquisition, data analysis, graphics, and also methodology to incorporate programs written in other languages into LabVIEW. Historically, according to Professor Essick, he developed a series of experiments for an upper division laboratory course for computer-based instrumentation. His observation was that while many students had the necessary background in computer programming languages, there were students who had virtually no concept about writing a computer program let alone a computer- based interfacing program. Thus the beginnings of a concept for not only teaching computer- based instrumentation techniques, but aiso a method for the beginner to experience writing a com- puter program.

    Full Text Available An Aerosol Time-Of-Flight Mass Spectrometer (ATOFMS was deployed to investigate the size-resolved chemical composition of single particles at an urban background site in Paris, France, as part of the MEGAPOLI winter campaign in January/February 2010. ATOFMS particle counts were scaled to match coincident Twin Differential Mobility Particle Sizer (TDMPS data in order to generate hourly size-resolved mass concentrations for the single particle classes observed. The total scaled ATOFMS particle mass concentration in the size range 150–1067 nm was found to agree very well with the sum of concurrent High-Resolution Time-of-Flight Aerosol Mass Spectrometer (HR-ToF-AMS and Multi-Angle Absorption Photometer (MAAP mass concentration measurements of organic carbon (OC, inorganic ions and black carbon (BC (R2 = 0.91. Clustering analysis of the ATOFMS single particle mass spectra allowed the separation of elemental carbon (EC particles into four classes: (i EC attributed to biomass burning (ECbiomass, (ii EC attributed to traffic (ECtraffic, (iii EC internally mixed with OC and ammonium sulfate (ECOCSOx, and (iv EC internally mixed with OC and ammonium nitrate (ECOCNOx. Average hourly mass concentrations for EC-containing particles detected by the ATOFMS were found to agree reasonably well with semi-continuous quantitative thermal/optical EC and optical BC measurements (r2 = 0.61 and 0.65–0.68 respectively, n = 552. The EC particle mass assigned to fossil fuel and biomass burning sources also agreed reasonably well with BC mass fractions assigned to the same sources using seven-wavelength aethalometer data (r2 = 0.60 and 0.48, respectively, n = 568.

    2009-02-01

    A biennial dataset of ambient particle number size distributions (diameter range 4-800 nm) collected in urban air in Leipzig, Germany, was analysed with respect to the influence of traffic emissions. Size distributions were sampled continuously in 2005 and 2006 inside a street canyon trafficked by ca. 10 000 motor vehicles per day, and at a background reference site distant at 1.5 km. Auto-correlation analysis showed that the impact of fresh traffic emissions could be seen most intensely below particle sizes of 60 nm. The traffic-induced concentration increment at roadside was estimated by subtracting the urban background values from the street canyon measurement. To describe the variable dispersion conditions inside the street canyon, micro-meteorological dilution factors were calculated using the Operational Street Pollution Model (OSPM), driven by above-roof wind speed and wind direction observations. The roadside increment concentrations, dilution factor, and real-time traffic counts were used to calculate vehicle emission factors (aerosol source rates) that are representative of the prevailing driving conditions, i.e. stop-and-go traffic including episodes of fluent traffic flow at speeds up to 40 km h-1. The size spectrum of traffic-derived particles was essentially bimodal - with mode diameters around 12 and 100 nm, while statistical analysis suggested that the emitted number concentration varied with time of day, wind direction, particle size and fleet properties. Significantly, the particle number emissions depended on ambient temperature, ranging between 4.8 (±1.8) and 7.8 (±2.9).1014 p. veh-1 km-1 in summer and winter, respectively. A separation of vehicle types according to vehicle length suggested that lorry-like vehicles emit about 80 times more particle number than passenger car-like vehicles. Using nitrogen oxide (NOx) measurements, specific total particle number emissions of 338 p. (pg NOx)-1 were inferred. The calculated traffic emission factors

    Full Text Available The influence of aerosol water uptake on the aerosol particle light scattering was examined at the regional continental research site Melpitz, Germany. The scattering enhancement factor f(RH, defined as the aerosol particle scattering coefficient at a certain relative humidity (RH divided by its dry value, was measured using a humidified nephelometer. The chemical composition and other microphysical properties were measured in parallel. f(RH showed a strong variation, e.g. with values between 1.2 and 3.6 at RH=85% and λ=550 nm. The chemical composition was found to be the main factor determining the magnitude of f(RH, since the magnitude of f(RH clearly correlated with the inorganic mass fraction measured by an aerosol mass spectrometer (AMS. Hysteresis within the recorded humidograms was observed and explained by long-range transported sea salt. A closure study using Mie theory showed the consistency of the measured parameters.

    A high number of aerosol particle shrinkage cases (70) have been identified and analyzed from an extensive and representative database of aerosol size distributions obtained between 2009 and 2015 at an urban background site in Madrid (Spain). A descriptive classification based on the process from which the shrinkage began is proposed according which shrinkage events were divided into three groups: (1) NPF + shrinkage (NPF + S) events, (2) aerosol particle growth process + shrinkage (G + S) events, and (3) pure shrinkage (S) events. The largest number of shrinkages corresponded to the S-type followed by NPF + S, while the G + S events were the least frequent group recorded. Duration of shrinkages varied widely from 0.75 to 8.5 h and SR from -1.0 to -11.1 nm h-1. These processes typically occurred in the afternoon, around 18:00 UTC, caused by two situations: i) a wind speed increase usually associated with a change in the wind direction (over 60% of the observations) and ii) the reduction of photochemical activity at the end of the day. All shrinkages were detected during the warm period, mainly between May and August, when local meteorological conditions (high solar irradiance and temperature and low relative humidity), atmospheric processes (high photochemical activity) and availability of aerosol-forming precursors were favorable for their development. As a consequence of these processes, the particles concentration corresponding to the Aitken mode decreased into the nucleation mode. The accumulation mode did not undergo significant changes during these processes. In some cases, a dilution of the particulate content in the ambient air was observed. This work, goes further than others works dealing with aerosol particles shrinkages, as it incorporates as a main novelty a classification methodology for studying these processes. Moreover, compared to other studies, it is supported by a high and representative number of observations. Thus, this study contributes to

    Although they are currently unregulated, atmospheric ultrafine particles (organic compounds onto particles. These processes had notable impacts on atmospheric particle number concentrations. All three emission scenarios (current legislation, optimized emissions, and maximum technically feasible reductions) resulted in substantial (10-50%) decreases in median particle number concentrations over Europe. Consistent reductions were predicted in Central Europe, while Northern Europe exhibited smaller reductions or even increased concentrations. Motivated by the improved NPF descriptions for ammonia and methylamines, we placed special focus on the potential to improve air quality by reducing agricultural emissions, which are a major source of these species. Agricultural emission controls showed promise in reducing ultrafine particle number concentrations, although the change is nonlinear with particle size.

    Interest in cosmic sources of high energy neutrinos dates back to the late 1950's. This paper outlines the interdisciplinary scientific agenda, which span the fields of astronomy, particle physics, and cosmic ray physics. While the general detection principles based on optical Cherenkov radiation have been understood for many years, the unusual geographic locations of suitable detector sites have challenged the ingenuity of experimentalists. Two high energy neutrino programs are now operating (NT200 in Lake Baikal and the AMANDA detector), with the expectation of ushering in the era of multi-messenger astronomy. Two Mediterranean-based programs have made impressive progress. These detectors are optimized to detect neutrinos with energies of the order of 1-10 TeV, although they are capable of detecting neutrinos over a much broader range of energies. For E{sub {nu}} > 10{sup 15} eV, several new ideas are being exploited to expand the effective volume of the detector. These techniques are based on the detection of neutrino-initiated cascades. We describe the ongoing worldwide efforts to develop expandable techniques and offer an assessment of their relative capabilities.

  8. Designing Viable Business Models for Living Labs

    2012-09-01

    Full Text Available Over 300 regions have integrated the concept of living labs into their economic development strategy since 2006, when the former Finnish Prime Minister Esko Aho launched the living lab innovation policy initiative during his term of European presidency. Despite motivating initial results, however, success cases of turning research into usable new products and services remain few and uncertainty remains on what living labs actually do and contribute. This practitioner-oriented article presents a business excellence model that shows processes of idea creation and team mobilization, new product development, user involvement, and entrepreneurship through which living labs deliver high-potential investment opportunities. Customers of living labs are identified as investors such as venture capitalists or industrial firms because living labs can generate revenue from them to create their own sustainable business model. The article concludes that living labs provide extensive support “lab” infrastructure and that it remains a formidable challenge to finance it, which calls for a more intensive debate.

    Full Text Available This study was conducted to investigate the protection of disposable filtering half-facepiece respirators of different grades against particles between 0.093 and 1.61 μm. A personal sampling system was used to particle size-selectively assess the protection of respirators. The results show that about 10.9% of FFP2 respirators and 28.2% of FFP3 respirators demonstrate assigned protection factors (APFs below 10 and 20, which are the levels assigned for these respirators by the British Standard. On average, the protection factors of FFP respirators were 11.5 to 15.9 times greater than those of surgical masks. The minimum protection factors (PFs were observed for particles between 0.263 and 0.384 μm. No significant difference in PF results was found among FFP respirator categories and particle size. A strong association between fit factors and protection factors was found. The study indicates that FFP respirators may not achieve the expected protection level and the APFs may need to be revised for these classes of respirators.

    The Las Cumbres Observatory Global Telescope Network (LCOGT) is an ambitious project to build and operate, within 5 years, a worldwide robotic network of 50 0.4, 1, and 2 m telescopes sharing identical instrumentation and optimized for precision photometry of time-varying sources. The telescopes, instrumentation, and software are all developed in house with two 2 m telescopes already installed. The LCOGT Imaging Lab is responsible for assembly and characterization of the network's cameras and instrumentation. In addition to a fully equipped CNC machine shop, two electronics labs, and a future optics lab, the Imaging Lab is designed from the ground up to be a superb environment for bare detectors, precision filters, and assembled instruments. At the heart of the lab is an ISO class 5 cleanroom with full ionization. Surrounding this, the class 7 main lab houses equipment for detector characterization including QE and CTE, and equipment for measuring transmission and reflection of optics. Although the first science cameras installed, two TEC cooled e2v 42-40 deep depletion based units and two CryoTiger cooled Fairchild Imaging CCD486-BI based units, are from outside manufacturers, their 18 position filter wheels and the remainder of the network's science cameras, controllers, and instrumentation will be built in house. Currently being designed, the first generation LCOGT cameras for the network's 1 m telescopes use existing CCD486-BI devices and an in-house controller. Additionally, the controller uses digital signal processing to optimize readout noise vs. speed, and all instrumentation uses embedded microprocessors for communication over ethernet.

    The effect of temperature changes on the light output of LAB based liquid scintillator is investigated in a range from -5 to 30°C with α -particles and electrons in a small scale setup. Two PMTs observe the scintillator liquid inside a cylindrically shaped aluminum cuvette that is heated or cooled and the temperature dependent PMT sensitivity is monitored and corrected. The α -emitting isotopes in dissolved radon gas and in natural Samarium (bound to a LAB solution) excite the liquid scintillator mixtures and changes in light output with temperature variation are observed by fitting light output spectra. Furthermore, also changes in light output by compton electrons, which are generated from external calibration γ -ray sources, is analysed with varying temperature. Assuming a linear behaviour, a combined negative temperature coefficient of {(-0.29 ± 0.01)}{ %/°}C is found. Considering hints for a particle type dependency, electrons show {(-0.17 ± 0.02)}{ %/°}C, whereas the temperature dependency seems stronger for α -particles, with {(-0.35 ± 0.03)}{ %/°}C. Due to a high sampling rate, a pulse shape analysis can be performed and shows an enhanced slow decay component at lower temperatures, pointing to reduced non-radiative triplet state de-excitations.

    Mr. Tautin reported on the seemingly everchanging structure of biological science units within the Interior Department. Current Congressional proposals would either change the name of the Bird Banding Lab's parent agency or make it part of the Geological Survey. The current Congress has not looked favorably on science budgets within the Interior Department, and the Banding Lab's budget is being squeezed ever tighter.

    As an undergraduate physics major who spent 2015 deep in a quantum optics lab at Oak Ridge National Laboratory, I knew my 2016 experience with the House of Representatives Energy and Commerce Committee would be a completely new challenge. I have long had a passion for the bridge of communication between the technical and non-technical worlds but it was only through my AIP Mather internship this summer that I was able to see that passion come to life in the realm of science policy. Suddenly, I went from squeezing political philosophy classes into my packed schedule to witnessing the political process first-hand. I was thrilled to find that the skills of critical thinking and communicating complex issues I have developed throughout my training as a physicist were directly applicable to my work in Congress. Overall, my experience this summer has given me insight into the inner workings of the federal policy process, deepened my appreciation for the work of government employees to keep Congressional members informed on the pressing current issues, and exposed me to a whole range of alternative careers within science.

    Full Text Available The size distribution of particulate nitrated and oxygenated polycyclic aromatic hydrocarbons (NPAHs and OPAHs was determined during two field campaigns at a traffic site in summer 2010 and at a suburban site during the MEGAPOLI (Megacities: Emissions, urban, regional and Global Atmospheric POLlution and climate effects, and Integrated tools for assessment and mitigation experiment in summer 2009. Both, OPAHs and NPAHs were strongly associated (>85% to fine particles (Dp< 2.5 μm increasing the interest of their study on a sanitary point of view. Results showed really different NPAH and OPAH particle size distributions between both sites. At traffic site, clearly bimodal (notably for NPAHs particle size distributions (Dp = 0.14 and 1.4 μm were observed, while the particle size distributions were more scattered at the suburban site, especially for OPAHs. Bimodal particle size distribution observed at traffic site for the NPAH could be assigned to the vehicle emissions and the particle resuspension. Broadest distribution observed at the suburban site could be attributed to the mass transfer of compounds by volatilization/sorption processes during the transport of particles in the atmosphere. Results also showed that the combination of the study of particle size distributions applied to marker compounds (primary: 1-nitropyrene; secondary: 2-nitrofluoranthene and to NPAH or OPAH chemical profiles bring some indications on their primary and/or secondary origin. Indeed, 1,4-anthraquinone seemed only primary emitted by vehicles while 7-nitrobenz[a]anthracene, benz[a]antracen7,12-dione and benzo[b]fluorenone seemed secondarily formed in the atmosphere.

    2013-01-01

    The Spaceport Processing System Development Lab (SPSDL), developed and maintained by the Systems Hardware and Engineering Branch (NE-C4), is a development lab with its own private/restricted networks. A private/restricted network is a network with restricted or no communication with other networks. This allows users from different groups to work on their own projects in their own configured environment without interfering with others utilizing their resources in the lab. The different networks being used in the lab have no way to talk with each other due to the way they are configured, so how a user configures his software, operating system, or the equipment doesn't interfere or carry over on any of the other networks in the lab. The SPSDL is available for any project in KSC that is in need of a lab environment. My job in the SPSDL was to assist in maintaining the lab to make sure it's accessible for users. This includes, but is not limited to, making sure the computers in the lab are properly running and patched with updated hardware/software. In addition to this, I also was to assist users who had issues in utilizing the resources in the lab, which may include helping to configure a restricted network for their own environment. All of this was to ensure workers were able to use the SPSDL to work on their projects without difficulty which would in turn, benefit the work done throughout KSC. When I wasn't working in the SPSDL, I would instead help other coworkers with smaller tasks which included, but wasn't limited to, the proper disposal, moving of, or search for essential equipment. I also, during the free time I had, used NASA's resources to increase my knowledge and skills in a variety of subjects related to my major as a computer engineer, particularly in UNIX, Networking, and Embedded Systems.

    2006-12-01

    Virtual Labs and Virtual Worlds Coastline Community College has under development several virtual lab simulations and activities that range from biology, to language labs, to virtual discussion environments. Imagine a virtual world that students enter online, by logging onto their computer from home or anywhere they have web access. Upon entering this world they select a personalized identity represented by a digitized character (avatar) that can freely move about, interact with the environment, and communicate with other characters. In these virtual worlds, buildings, gathering places, conference rooms, labs, science rooms, and a variety of other “real world” elements are evident. When characters move about and encounter other people (players) they may freely communicate. They can examine things, manipulate objects, read signs, watch video clips, hear sounds, and jump to other locations. Goals of critical thinking, social interaction, peer collaboration, group support, and enhanced learning can be achieved in surprising new ways with this innovative approach to peer-to-peer communication in a virtual discussion world. In this presentation, short demos will be given of several online learning environments including a virtual biology lab, a marine science module, a Spanish lab, and a virtual discussion world. Coastline College has been a leader in the development of distance learning and media-based education for nearly 30 years and currently offers courses through PDA, Internet, DVD, CD-ROM, TV, and Videoconferencing technologies. Its distance learning program serves over 20,000 students every year. sponsor Jerry Meisner

    The work performed in Dr. Rhoton's Lab, represented by over 500 publications on microneurosurgical anatomy, greatly contributed to improving the level of neurosurgical treatment throughout the world. The authors reviewed the development and activities of the Lab over 40 years. Dr. Albert L. Rhoton Jr., the founder of, and leader in, this field, displayed great creativity and ingenuity during his life. He devoted himself to perfecting his study methodology, employing high-definition photos and slides to enhance the quality of his published papers. He dedicated his life to the education of neurosurgeons. His "lab team," which included microneuroanatomy research fellows, medical illustrators, lab directors, and secretaries, worked together under his leadership to develop the methods and techniques of anatomical study to complete over 160 microneurosurgical anatomy projects. The medical illustrators adapted computer technologies and integrated art and science in the field of microneurosurgical anatomy. Dr. Rhoton's fellows established methods of injecting colors and pursued a series of projects to innovate surgical approaches and instruments over a 40-year period. They also continued to help Dr. Rhoton to conduct international educational activities after returning to their home countries. Rhoton's Lab became a world-renowned anatomical lab as well as a microsurgical training center and generated the knowledge necessary to perform accurate, gentle, and safe surgery for the sake of patients.

    2017-01-01

    Chemistry labs can become a dangerous environment for students as the lab exercises involve hazardous chemicals, glassware, and equipment. Approximately one hundred thousand students take chemistry laboratory classes annually in Nepal. We conducted a survey on chemical lab safety issues across Nepal. In this paper, we assess the safety policy and equipment, protocols and procedures followed, and waste disposal in chemistry teaching labs. Significant population of the respondents believed that there is no monitoring of the lab safety in their lab (p<0.001). Even though many labs do not allow food and beverages inside lab and have first aid kits, they lack some basic safety equipment. There is no institutional mechanism to dispose lab waste and chemical waste is disposed haphazardly. Majority of the respondents believed that the safety training should be a part of educational training (p = 0.001) and they would benefit from short course and/or workshop on lab safety (p<0.001).

    The high resolution hydrogen bubble chamber LEBC has already been used in experiments at the SPS to detect particles with lifetime $\\geq 5 \\times 10^{-13}$s (NA13 & NA16). \\\\\\\\For this experiment, a new version of LEBC called HOLEBC, has been constructed. This chamber and the NA26 version of the spectrometer have been used with classical optics in the NA27 experiment. A significant improvement in resolution was achieved ($\\simeq$ 20 microns compared with $\\simeq$ 40 $\\mu$m in LEBC) and hence a good sensitivity to all (known) charmed particle decays. The development of holographic recording techniques with HOLEBC is in progress. \\\\\\\\The prototype NA26 experiment is designed to evaluate the feasibility of the high sensitivity, high resolution holographic hydrogen bubble chamber technique and evaluate various possible charm selective triggers using the information from the spectrometer.

    2017-04-01

    ESCAPE is a mission proposed in response to the ESA-M5 call that will quantitatively estimate the amount of escaping particles of the major atmospheric components (nitrogen and oxygen), as neutral and ionised species, escaping from the Earth as a magnetised planet. The spatial distribution and temporal variability of the flux of these species and their isotopic composition will be for the first time systematically investigated in an extended altitude range, from the exobase/upper ionosphere (500 km altitude) up to the magnetosphere. The goal is to understand the importance of each escape mechanism, its dependence on solar and geomagnetic activity, and to infer the history of the Earth's atmosphere over a long (geological scale) time period. Since the solar EUV and solar wind conditions during solar maximum at present are comparable to the solar minimum conditions 1-2 billion years ago, the escaping amount and the isotope and N/O ratios should be obtained as a function of external forcing (solar and geomagnetic conditions) to allow a scaling to the past. The result will be used as a reference to understand the atmospheric/ionospheric evolution of magnetised planets. To achieve this goal, a slowly spinning spacecraft is proposed equipped with a suite of instruments developed and supplied by an international consortium. These instruments will detect the upper atmosphere and magnetosphere escaping populations by a combination of in-situ measurements and of remote-sensing observations.

    2011-04-01

    Jefferson Lab Jefferson Lab was created in 1984 and started operating in about 1996. 2011 is an appropriate time to try to take a look at the results that have appeared, what has been learned, and what has been exciting for our scientific community. Rather than attempt to construct a coherent view with a single author or at least a small number, we have, instead, invited small groups of people who have been intimately involved in the work itself to make contributions. These people are accelerator experts, experimentalists and theorists, staff and users. We have, in the main, sought reviews of the actual sub-fields. The primary exception is the first paper, which sets the scene as it was, in one person's view, at the beginning of Jefferson Lab. In reviewing the material as it appeared, I was impressed by the breadth of the material. Major advances are documented from form factors to structure functions, from spectroscopy to physics beyond the standard model of nuclear and particle physics. Recognition of the part played by spin, the helicities of the beams, the polarizations of the targets, and the polarizations of final state particles, is inescapable. Access to the weak interaction amplitudes through measurements of the parity violating asymmetries has led to quantification of the strange content of the nucleon and the neutron radius of lead, and to measurements of the electroweak mixing angle. Lattice QCD calculations flourished and are setting the platform for understanding of the spectroscopy of baryons and mesons. But the star of the game was the accelerator. Its performance enabled the physics and also the use of the technology to generate a powerful free electron laser. These important pieces of Jefferson Lab physics are given their place. As the third Director of Jefferson Lab, and on behalf of the other physicists and others presently associated with the lab, I would like to express my admiration and gratitude for the efforts of the directors, chief

    2013-01-01

    Political theory of European union, through an engagement between political concepts and theoretical understandings, provides a means of identifying the EU as a political object. It is argued that understanding the projects, processes and products of European union, based on ‘sharing’ or ‘communion......’, provides a better means of perceiving the EU as a political object rather than terms such as ‘integration’ or ‘co-operation’. The concept of ‘European communion’ is defined as the ‘subjective sharing of relationships’, understood as the extent to which individuals or groups believe themselves to be sharing...... relations (or not), and the consequences of these beliefs for European political projects, processes and products. By exploring European communion through an engagement with contemporary political theory, using very brief illustrations from the Treaty of Lisbon, the article also suggests that European...

    The NASA Astrophysics Data System (ADS) has been working hard on updating its services and interfaces to better support our community's research needs. ADS Labs is a new interface built on the old tried-and-true ADS Abstract Databases, so all of ADS's content is available through it. In this presentation we highlight the new features that have been developed in ADS Labs over the last year: new recommendations, metrics, a citation tool and enhanced fulltext search. ADS Labs has long been providing article-level recommendations based on keyword similarity, co-readership and co-citation analysis of its corpus. We have now introduced personal recommendations, which provide a list of articles to be considered based on a individual user's readership history. A new metrics interface provides a summary of the basic impact indicators for a list of records. These include the total and normalized number of papers, citations, reads, and downloads. Also included are some of the popular indices such as the h, g and i10 index. The citation helper tool allows one to submit a set of records and obtain a list of top 10 papers which cite and/or are cited by papers in the original list (but which are not in it). The process closely resembles the network approach of establishing "friends of friends" via an analysis of the citation network. The full-text search service now covers more than 2.5 million documents, including all the major astronomy journals, as well as physics journals published by Springer, Elsevier, the American Physical Society, the American Geophysical Union, and all of the arXiv eprints. The full-text search interface interface allows users and librarians to dig deep and find words or phrases in the body of the indexed articles. ADS Labs is available at http://adslabs.org

    2017-04-01

    A detailed study of heavy metals distribution in various soil grain-size fractions helps to increase the knowledge about the complex nature of metals' occurrence and their distribution pathways in the environment. On the basis of particle size fractionation of topsoil horizons we examined the specific behavior of heavy metals in a small erosional landform located in the humid temperate zone of the Russian Plain. The object of the study is a 400 m small U-shaped dry valley (balka in Russian) with a catchment area of 32.8 ha located in the central part of the Protva river basin, 100 km southwest of Moscow. The uppermost parts of the landform are incised in Late Pleistocene loessial loams, which cover significant portions of interfluve area in the region, while the middle and the lower parts cut through Middle Pleistocene glacial sediments. A total of 50 samples were collected from topsoil horizons of different landform geomorphic units along three cross-sections as well as along the bottom of the landform and its detrital fan. Samples were analyzed for Mn, Cu, Ni, Co, Cr, Zn, Pb, Ti, Zr, and Fe content. Eleven samples were chosen for physical fractionation into 5 grain-size fractions (1-0.25 mm, 0.25-0.05 mm, 0.05-0.01 mm, 0.01-0.001 mm and calculated for Cu, Ni, Co, Fe, Mn, Ti and Zr reach their maximum in the 1-0.25 mm fraction (for Cu and Ni exceeding 75%, for Ti, Zr being around 40%). For Zn, Cr and Pb the maximum variation (50-60%) was found in the 0.25-0.05 mm fraction. In contrast, the two studied silt fractions and also the clay showed very low variations of all metal contents (except for Mn) characteristically in the range between 6% (Cr) and 23.5% (Zn). Unlike the finer fractions, which displayed very poor geochemical differentiation across the landform's geomorphic units, the coarser (sand) fractions showed distinct spatial patterns in the elements' distribution, possibly related to migration processes, the depletion of metals in the landforms' slopes and

    Dispatchable electricity generation on demand is a fundamental issue for commercial deployment of Concentrated Solar Power (CSP) plants. One of the promising routes to overcome the intermittence of the solar resource is the use of thermochemical energy storage systems based on redox reactions of metal oxides. Different metal oxides might potential candidates as storing material depending on the foreseen working temperature range. In the framework of the FP7 European project TCSPower, a particle-based reactor is used to analyze this type of materials. The lab-scale thermochemical reactor is initially tested using an inert material (alumina particles) instead of reactants in order to study its thermal performance. Thermocouples installed inside the system at various positions monitor the experiments. A three dimensional numerical model is developed to investigate the flow and heat transfer in the reactor. The governing equations - mass, momentum and energy conservation - are solved by the finite element method in the commercial software COMSOL Multiphysics. Simulations are performed for the experimental conditions. Experimentally measured and numerically predicted temperature profiles at various locations inside the system are compared and presented in this paper.

  12. LAB - Transition between Fossil and Present-Day Flow-Related Seismic Anisotropy

    Science.gov (United States)

    Plomerova, J.; Babuska, V.; Vecsey, L.; Munzarova, H.

    2015-12-01

    Topography of the lithosphere-asthenosphere boundary (LAB) and structure of the continental lithosphere record geodynamic development of the outer parts of the Earth. Studying the architecture of plates and mapping the LAB discontinuity relief can help to answer questions how and when the plates assembled and to what extent they were later deformed. Differences in changes of physical properties across the "discontinuities" are significant, but sharpness of the transitions depends on optics we are using. Moreover, the nature of the boundary/transition remains uncertain. Fundamental difference in origin and orientation of seismic anisotropy in the mantle lithosphere and in the sub-lithospheric mantle has led us to develop an original approach of LAB modelling. We associate the LAB with a transition of fossil anisotropy in the rigid high-velocity lithosphere to present-day related anisotropy in the more viscous underlying asthenosphere. We present a global LAB model calculated from depth-dependences of azimuthal and radial anisotropy of surface waves (Plomerova et al., 2002) and a uniform model of the European LAB (Plomerova and Babuska, 2010), calculated from P-wave travel times collected during regional passive experiments. In the latter, the LAB is modelled according to an empirical residual-depth relation. The high velocity contrast across the LAB (δvP ~ 0.6 km/s) required by the empirical gradient cannot be accomplished by isotropic velocities of materials forming the upper mantle, while it can be explained by different orientations of the high-velocities above and below the LAB. Relief of the lower plate boundary can vary considerably on short lateral distances and it is exposed to erosion from asthenosphere. On the other hand, dipping fabrics of often sharply bounded lithospheric domains, created probably during a plate formation, indicate stability of such a fossilized structure, which alters only near the domain boundaries.

  16. Encouraging entrepreneurship in university labs: Research activities, research outputs, and early doctorate careers

    Science.gov (United States)

    2017-01-01

    This paper investigates how the encouragement of entrepreneurship within university research labs relates with research activities, research outputs, and early doctorate careers. Utilizing a panel survey of 6,840 science & engineering doctoral students at 39 R1 research universities, this study shows that entrepreneurship is widely encouraged across university research labs, ranging from 54% in biomedical engineering to 18% in particle physics, while only a small share of labs openly discourage entrepreneurship, from approximately 3% in engineering to approximately 12% in the life sciences. Within fields, there is no difference between labs that encourage entrepreneurship and those that do not with respect to basic research activity and the number of publications. At the same time, labs that encourage entrepreneurship are significantly more likely to report invention disclosures, particularly in engineering where such labs are 41% more likely to disclose inventions. With respect to career pathways, PhDs students in labs that encourage entrepreneurship do not differ from other PhDs in their interest in academic careers, but they are 87% more likely to be interested in careers in entrepreneurship and 44% more likely to work in a startup after graduation. These results persist even when accounting for individuals’ pre-PhD interest in entrepreneurship and the encouragement of other non-academic industry careers. PMID:28178270

    When curricular materials are disseminated to new sites, there can be a tension between fidelity to the original intent of the developers and adaptation to local needs. In this case study we look at a lab activity that was initially developed for an introductory physics for the life sciences (IPLS) course at the University of Maryland, then implemented at George Mason University with significant adaptations. The goals of the two implementations were overlapping, but also differed in ways that are reflected in the two versions of the lab. We compare student lab report data from the two sites to examine the impacts of the adaptation on how students engaged with the lab.

    Energy Technology Data Exchange (ETDEWEB)

    Hogan, Craig

    2013-03-24

    Standard particle theory is based on quantized matter embedded in a classical geometry. Here, a complementary model is proposed, based on classical matter -- massive bodies, without quantum properties -- embedded in a quantum geometry. It does not describe elementary particles, but may be a better, fully consistent quantum description for position states in laboratory-scale systems. Gravitational theory suggests that the geometrical quantum system has an information density of about one qubit per Planck length squared. If so, the model here predicts that the quantum uncertainty of geometry creates a new form of noise in the position of massive bodies, detectable by interferometers.

    Labs on chips are manufactured in many shapes and sizes and can be used for numerous applications, from medical tests to water quality monitoring to detecting the signatures of life on other planets. The eight holes on this chip are actually ports that can be filled with fluids or chemicals. Tiny valves control the chemical processes by mixing fluids that move in the tiny channels that look like lines, connecting the ports. Scientists at NASA's Marshall Space Flight Center (MSFC) in Huntsville, Alabama designed this chip to grow biological crystals on the International Space Station. Through this research, they discovered that this technology is ideally suited for solving the challenges of the Vision for Space Exploration. For example, thousands of chips the size of dimes could be loaded on a Martian rover looking for biosignatures of past or present life. Other types of chips could be placed in handheld devices used to monitor microbes in water or to quickly conduct medical tests on astronauts. (NASA/MSFC/D.Stoffer)

    Lab-centric instruction emphasizes supervised, hands-on activities by substituting lab for lecture time. It combines a multitude of pedagogical techniques into the format of an extended, structured closed lab. We discuss the range of benefits for students, including increased staff interaction, frequent and varied self-assessments, integrated collaborative activities, and a systematic sequence of activities that gradually increases in difficulty. Instructors also benefit from a deeper window into student progress and understanding. We follow with discussion of our experiences in courses at U.C. Berkeley, and using data from some of these investigate the effects of lab-centric instruction on student learning, procrastination, and course pacing. We observe that the lab-centric format helped students on exams but hurt them on extended programming assignments, counter to our hypothesis. Additionally, we see no difference in self-ratings of procrastination and limited differences in ratings of course pace. We do find evidence that the students who choose to attend lab-centric courses are different in several important ways from students who choose to attend the same course in a non-lab-centric format.

    Bohr, Teresa M.

    This study of online science teachers' opinions addressed the use of virtual labs in online courses. A growing number of schools use virtual labs that must meet mandated laboratory standards to ensure they provide learning experiences comparable to hands-on labs, which are an integral part of science curricula. The purpose of this qualitative case study was to examine teachers' perceptions of the quality and effectiveness of high school virtual labs. The theoretical foundation was constructivism, as labs provide student-centered activities for problem solving, inquiry, and exploration of phenomena. The research questions focused on experienced teachers' perceptions of the quality of virtual vs. hands-on labs. Data were collected through survey questions derived from the lab objectives of The Next Generation Science Standards . Eighteen teachers rated the degree of importance of each objective and also rated how they felt virtual labs met these objectives; these ratings were reported using descriptive statistics. Responses to open-ended questions were few and served to illustrate the numerical results. Many teachers stated that virtual labs are valuable supplements but could not completely replace hands-on experiences. Studies on the quality and effectiveness of high school virtual labs are limited despite widespread use. Comprehensive studies will ensure that online students have equal access to quality labs. School districts need to define lab requirements, and colleges need to specify the lab experience they require. This study has potential to inspire positive social change by assisting science educators, including those in the local school district, in evaluating and selecting courseware designed to promote higher order thinking skills, real-world problem solving, and development of strong inquiry skills, thereby improving science instruction for all high school students.

    DNA is increasingly used as an important tool in programming the self-assembly of micrometer- and nanometer-scale particles. This is largely due to the highly specific thermoreversible interaction of cDNA strands, which, when placed on different particles, have been used to bind precise pairs in aggregates and crystals. However, DNA functionalized particles will only reach their true potential for particle assembly when each particle can address and bind to many different kinds of particles. ...

    The notion of laboratory or simply 'lab' has become popular in recent years in areas outside science and technology development. Learning Labs, Innovation Labs, Usability Labs, Media and Communication Labs and even Art Labs designate institutions or fora dedicated to change and experimentation...... as others have frequently used other metaphors like workshop, studio or atelier in design research. In this article we will argue that the laboratory metaphor is particularly suitable and useful for the design:lab, and we will give examples of how we have worked with the design:lab as a platform...

  11. Labs not in a lab: A case study of instructor and student perceptions of an online biology lab class

    Science.gov (United States)

    Doiron, Jessica Boyce

    Distance learning is not a new phenomenon but with the advancement in technology, the different ways of delivering an education have increased. Today, many universities and colleges offer their students the option of taking courses online instead of sitting in a classroom on campus. In general students like online classes because they allow for flexibility, the comfort of sitting at home, and the potential to save money. Even though there are advantages to taking online classes, many students and instructors still debate the effectiveness and quality of education in a distant learning environment. Many universities and colleges are receiving pressure from students to offer more and more classes online. Research argues for both the advantages and disadvantages of online classes and stresses the importance of colleges and universities weighing both sides before deciding to adopt an online class. Certain classes may not be suitable for online instruction and not all instructors are suitable to teach online classes. The literature also reveals that there is a need for more research on online biology lab classes. With the lack of information on online biology labs needed by science educators who face the increasing demand for online biology labs, this case study hopes to provide insight into the use of online biology lab classes and the how students and an instructor at a community college in Virginia perceive their online biology lab experience as well as the effectiveness of the online labs.

    Lab practices are an essential part of teaching in Engineering. However, traditional laboratory lessons developed in classroom labs (CL) must be adapted to teaching and learning strategies that go far beyond the common concept of e-learning, in the sense that completely virtualized distance education disconnects teachers and students from the real world, which can generate specific problems in laboratory classes. Current proposals of virtual labs (VL) and remote labs (RL) do not either cover new needs properly or contribute remarkable improvement to traditional labs—except that they favor distance training. Therefore, online teaching and learning in lab practices demand a further step beyond current VL and RL. This paper poses a new reality and new teaching/learning concepts in the field of lab practices in engineering. The developed augmented reality-based lab system (augmented remote lab, ARL) enables teachers and students to work remotely (Internet/intranet) in current CL, including virtual elements which interact with real ones. An educational experience was conducted to assess the developed ARL with the participation of a group of 10 teachers and another group of 20 students. Both groups have completed lab practices of the contents in the subjects Digital Systems and Robotics and Industrial Automation, which belong to the second year of the new degree in Electronic Engineering (adapted to the European Space for Higher Education). The labs were carried out by means of three different possibilities: CL, VL and ARL. After completion, both groups were asked to fill in some questionnaires aimed at measuring the improvement contributed by ARL relative to CL and VL. Except in some specific questions, the opinion of teachers and students was rather similar and positive regarding the use and possibilities of ARL. Although the results are still preliminary and need further study, seems to conclude that ARL remarkably improves the possibilities of current VL and RL

    Full Text Available One and key of the priorities in laboratory medicine is improvement of quality management system for patient safety. Quality in the health care is tightly connected to the level of excellence of the health care provided in relation to the current level of knowledge and technical development. Accreditation is an effective way to demonstrate competence of the laboratory, a tool to recognize laboratories world-wide, is linked to periodical audits, to stimulate the maintenance and improvement of the quality, which leads to high standard of services for clients (patients, health care providers, etc.. The strategic plans of IFCC and EFLM include focusing on accreditation of labs based on ISO standards and cooperation with European Accreditation and national accreditation bodies. IFCC and EFLM recognised that ISO 15189:2012 Medical laboratories – Requirements for quality and competence, encompasses all the assessment criteria specified in the policy of quality. The last version is oriented to process approach with detailed division and clearly defined requirements. The accreditation of labs improves facilitation of accurate and rapid diagnostics, efficiency of treatment and reduction of errors in the laboratory process. Accreditation is not about who the best is, but who has a system of standard procedures with aim to improve the quality and patient safety. Quality system is about people, with people and for people.

  18. LAB building a home for scientists

    CERN Document Server

    Fishman, Mark C

    2017-01-01

    Laboratories are both monasteries and space stations, redolent of the great ideas of generations past and of technologies to propel the future. Yet standard lab design has changed only little over recent years. Here Mark Fishman describes how to build labs as homes for scientists, to accommodate not just their fancy tools, but also their personalities. This richly illustrated book explores the roles of labs through history, from the alchemists of the Middle Ages to the chemists of the 19th and 20th centuries, and to the geneticists and structural biologists of today, and then turns to the special features of the laboratories Fishman helped to design in Cambridge, Shanghai, and Basel. Anyone who works in, or plans to build a lab, will enjoy this book, which will encourage them to think about how this special environment drives or impedes their important work.

    2006-10-01

    Full Text Available This paper discusses the problem of virtual lab capabilities in the e-learning. Using combination of web conferencing and "virtual labs" capabilities, a new quality distance learning teaching is now in preparation and will be included in the course teaching to produce interactive, online simulations for the natural gas engineering studies. The activities are designed to enhance the existing curriculum and to include online assessments. A special care is devoted to the security problem between a server and a client computer. Several examples of the virtual labs related to the PVT thermodynamics, fluid flow, the natural gas well-testing, and thev gas network flow are prepared and tested. A major challenge for the 'CELGAS' system is in managing the delicate balance between the student collaboration and the isolation. Students may be encouraged to collaborate and work with each other, simulating their exploration of the lab material.

    Nie, Min; Gao, Zhen Y; Wu, Xin Y; Jiang, Chen X; Du, Jia H

    2015-12-07

    According to the updated concept of oral microbiology, the School of Stomatology, Wuhan University, has carried out oral microbiology teaching reforms during the last 5 years. There was no lab curriculum before 2009 except for a theory course of oral microbiology. The school has implemented an innovative curriculum with oral medicine characteristics to strengthen understanding of knowledge, cultivate students' scientific interest and develop their potential, to cultivate the comprehensive ability of students. This study was designed to evaluate the oral microbiology lab curriculum by analyzing student performance and perceptions regarding the curriculum from 2009 to 2013. The lab curriculum adopted modalities for cooperative learning. Students collected dental plaque from each other and isolated the cariogenic bacteria with selective medium plates. Then they purified the enrichment culture medium and identified the cariogenic strains by Gram stain and biochemical tests. Both quantitative and qualitative data for 5 years were analysed in this study. Part One of the current study assessed student performance in the lab from 2009 to 2013. Part Two used qualitative means to assess students' perceptions by an open questionnaire. The 271 study students' grades on oral microbiology improved during the lab curriculum: "A" grades rose from 60.5 to 81.2 %, and "C" grades fell from 28.4 to 6.3 %. All students considered the lab curriculum to be interesting and helpful. Quantitative and qualitative data converge to suggest that the lab curriculum has strengthened students' grasp of important microbiology-related theory, cultivated their scientific interest, and developed their potential and comprehensive abilities. Our student performance and perception data support the continued use of the innovative teaching system. As an extension and complement of the theory course, the oral microbiology lab curriculum appears to improve the quality of oral medicine education and help to

    Balakrishnan, B.; Woods, P. C.

    2013-05-01

    Over the years, rapid development in computer technology has engendered simulation-based laboratory (lab) in addition to the traditional hands-on (physical) lab. Many higher education institutions adopt simulation lab, replacing some existing physical lab experiments. The creation of new systems for conducting engineering lab activities has raised concerns among educators on the merits and shortcomings of both physical and simulation labs; at the same time, many arguments have been raised on the differences of both labs. Investigating the effectiveness of both labs is complicated, as there are multiple factors that should be considered. In view of this challenge, a study on students' perspectives on their experience related to key aspects on engineering laboratory exercise was conducted. In this study, the Visual Auditory Read and Kinetic model was utilised to measure the students' cognitive styles. The investigation was done through a survey among participants from Multimedia University, Malaysia. The findings revealed that there are significant differences for most of the aspects in physical and simulation labs.

  12. RoboLab and virtual environments

    A useful adjunct to the manned space station would be a self-contained free-flying laboratory (RoboLab). This laboratory would have a robot operated under telepresence from the space station or ground. Long duration experiments aboard RoboLab could be performed by astronauts or scientists using telepresence to operate equipment and perform experiments. Operating the lab by telepresence would eliminate the need for life support such as food, water and air. The robot would be capable of motion in three dimensions, have binocular vision TV cameras, and two arms with manipulators to simulate hands. The robot would move along a two-dimensional grid and have a rotating, telescoping periscope section for extension in the third dimension. The remote operator would wear a virtual reality type headset to allow the superposition of computer displays over the real-time video of the lab. The operators would wear exoskeleton type arms to facilitate the movement of objects and equipment operation. The combination of video displays, motion, and the exoskeleton arms would provide a high degree of telepresence, especially for novice users such as scientists doing short-term experiments. The RoboLab could be resupplied and samples removed on other space shuttle flights. A self-contained RoboLab module would be designed to fit within the cargo bay of the space shuttle. Different modules could be designed for specific applications, i.e., crystal-growing, medicine, life sciences, chemistry, etc. This paper describes a RoboLab simulation using virtual reality (VR). VR provides an ideal simulation of telepresence before the actual robot and laboratory modules are constructed. The easy simulation of different telepresence designs will produce a highly optimum design before construction rather than the more expensive and time consuming hardware changes afterwards.

    Pekas, Nikola Slobodan [Iowa State Univ., Ames, IA (United States)

    2006-01-01

    This study establishes a set of magnetics-based tools that have been integrated with microfluidic systems. The overall impact of the work begins to enable the rapid and efficient manipulation and detection of magnetic entities such as particles, picoliter-sized droplets, or bacterial cells. Details of design, fabrication, and theoretical and experimental assessments are presented. The manipulation strategy has been demonstrated in the format of a particle diverter, whereby micron-sized particles are actively directed into desired flow channels at a split-flow junction by means of integrated microelectromagnets. Magnetic detection has been realized by deploying Giant Magnetoresistance (GMR) sensors--microfabricated structures originally developed for use as readout elements in computer hard-drives. We successfully transferred the GMR technology to the lab-on-a-chip arena, and demonstrated the versatility of the concept in several important areas: real-time, integrated monitoring of the properties of multiphase droplet flows; rapid quantitative determination of the concentration of magnetic nanoparticles in droplets of ferrofluids; and high-speed detection of individual magnetic microparticles and magnetotactic bacteria. The study also includes novel schemes for hydrodynamic flow focusing that work in conjunction with GMR-based detection to ensure precise navigation of the sample stream through the GMR detection volume, therefore effectively establishing a novel concept of a microfabricated magnetic flow cytometer.

  5. Collaborative Creation of a Lab Rubric

    Directory of Open Access Journals (Sweden)

    Carrie Miller-DeBoer

    2011-03-01

    Full Text Available While there are a number of tested rubrics in circulation, our task was to intervene in a particular situation: the lead professor was concerned because her graduate teaching assistants held negative views about student performance on the lab reports. GTAs found poor products frustrating, and admitted that their grading was thus superficial and provided no feedback to students. Specifically, GTAs did not feel equipped to evaluate writing and, as a result, simply graded on steps completed in the lab process.We have a rubric now for an Introduction to Zoology lab that could be submitted here as a pretty darn good rubric for other instructors to use. But the intent of our “Tips and Tools” is to describe the actual creation of the rubric. We believe the active “real time” development of the rubric carried as much or more value than the finished product.

  6. A Moodle extension to book online labs

    2005-11-01

    Full Text Available The social constructivist philosophy of Moodle makes it an excellent choice to deliver e-learning contents that require collaborative activities, such as those that are associated with online labs. In the case of online labs that enable web access to real devices (remote workbenches, access time should be reserved beforehand. A booking tool will avoid access conflicts and at the same time will help the students to organise their time and activities. This paper presents a Moodle extension that was developed within the Leonardo da Vinci MARVEL project, with the objective of meeting this requirement. The booking tool presented enables resource sharing in general and may be used to organise access to any type of scarce resources, such as to online labs and to the videoconferencing rooms that are needed to support collaborative activities.

  13. The StratusLab cloud distribution: Use-cases and support for scientific applications

    Science.gov (United States)

    Floros, E.

    2012-04-01

    The StratusLab project is integrating an open cloud software distribution that enables organizations to setup and provide their own private or public IaaS (Infrastructure as a Service) computing clouds. StratusLab distribution capitalizes on popular infrastructure virtualization solutions like KVM, the OpenNebula virtual machine manager, Claudia service manager and SlipStream deployment platform, which are further enhanced and expanded with additional components developed within the project. The StratusLab distribution covers the core aspects of a cloud IaaS architecture, namely Computing (life-cycle management of virtual machines), Storage, Appliance management and Networking. The resulting software stack provides a packaged turn-key solution for deploying cloud computing services. The cloud computing infrastructures deployed using StratusLab can support a wide range of scientific and business use cases. Grid computing has been the primary use case pursued by the project and for this reason the initial priority has been the support for the deployment and operation of fully virtualized production-level grid sites; a goal that has already been achieved by operating such a site as part of EGI's (European Grid Initiative) pan-european grid infrastructure. In this area the project is currently working to provide non-trivial capabilities like elastic and autonomic management of grid site resources. Although grid computing has been the motivating paradigm, StratusLab's cloud distribution can support a wider range of use cases. Towards this direction, we have developed and currently provide support for setting up general purpose computing solutions like Hadoop, MPI and Torque clusters. For what concerns scientific applications the project is collaborating closely with the Bioinformatics community in order to prepare VM appliances and deploy optimized services for bioinformatics applications. In a similar manner additional scientific disciplines like Earth Science can take

  7. A Hardware Lab Anywhere At Any Time

    Directory of Open Access Journals (Sweden)

    Tobias Schubert

    2004-12-01

    Full Text Available Scientific technical courses are an important component in any student's education. These courses are usually characterised by the fact that the students execute experiments in special laboratories. This leads to extremely high costs and a reduction in the maximum number of possible participants. From this traditional point of view, it doesn't seem possible to realise the concepts of a Virtual University in the context of sophisticated technical courses since the students must be "on the spot". In this paper we introduce the so-called Mobile Hardware Lab which makes student participation possible at any time and from any place. This lab nevertheless transfers a feeling of being present in a laboratory. This is accomplished with a special Learning Management System in combination with hardware components which correspond to a fully equipped laboratory workstation that are lent out to the students for the duration of the lab. The experiments are performed and solved at home, then handed in electronically. Judging and marking are also both performed electronically. Since 2003 the Mobile Hardware Lab is now offered in a completely web based form.

    2008-06-01

    Full Text Available This article details an experimental system developed to enhance the education and research in the area of wireless networks technologies. The system referred, as Virtual Lab (VL is primarily targeting first time users or users with limited experience in programming and using wireless sensor networks. The VL enables a set of predefined sensor networks to be remotely accessible and controlled for constructive and time-efficient experimentation. In order to facilitate the user's wireless sensor applications, the VL is using three main components: a a Virtual Lab Motes (VLM, representing the wireless sensor, b a Virtual Lab Client (VLC, representing the user's tool to interact with the VLM and c a Virtual Lab Server (VLS representing the software link between the VLM and VLC. The concept has been proven using the moteiv produced Tmote Sky modules. Initial experimental use clearly demonstrates that the VL approach reduces dramatically the learning curve involved in programming and using the associated wireless sensor nodes. In addition the VL allows the user's focus to be directed towards the experiment and not towards the software programming challenges.

    NASA's GeneLab aims to greatly increase the number of scientists that are using data from space biology investigations on board ISS, emphasizing a systems biology approach to the science. When completed, GeneLab will provide the integrated software and hardware infrastructure, analytical tools and reference datasets for an assortment of model organisms. GeneLab will also provide an environment for scientists to collaborate thereby increasing the possibility for data to be reused for future experimentation. To maximize the value of data from life science experiments performed in space and to make the most advantageous use of the remaining ISS research window, GeneLab will apply an open access approach to conducting spaceflight experiments by generating, and sharing the datasets derived from these biological studies in space.Onboard the ISS, a wide variety of model organisms will be studied and returned to Earth for analysis. Laboratories on the ground will analyze these samples and provide genomic, transcriptomic, metabolomic and proteomic data. Upon receipt, NASA will conduct data quality control tasks and format raw data returned from the omics centers into standardized, annotated information sets that can be readily searched and linked to spaceflight metadata. Once prepared, the biological datasets, as well as any analysis completed, will be made public through the GeneLab Space Bioinformatics System webb as edportal. These efforts will support a collaborative research environment for spaceflight studies that will closely resemble environments created by the Department of Energy (DOE), National Center for Biotechnology Information (NCBI), and other institutions in additional areas of study, such as cancer and environmental biology. The results will allow for comparative analyses that will help scientists around the world take a major leap forward in understanding the effect of microgravity, radiation, and other aspects of the space environment on model organisms

    DNA is increasingly used as an important tool in programming the self-assembly of micrometer- and nanometer-scale particles. This is largely due to the highly specific thermoreversible interaction of cDNA strands, which, when placed on different particles, have been used to bind precise pairs in aggregates and crystals. However, DNA functionalized particles will only reach their true potential for particle assembly when each particle can address and bind to many different kinds of particles. Indeed, specifying all bonds can force a particular designed structure. In this paper, we present the design rules for multiflavored particles and show that a single particle, DNA functionalized with many different "flavors," can recognize and bind specifically to many different partners. We investigate the cost of increasing the number of flavors in terms of the reduction in binding energy and melting temperature. We find that a single 2-μm colloidal particle can bind to 40 different types of particles in an easily accessible time and temperature regime. The practical limit of ∼100 is set by entropic costs for particles to align complementary pairs and, surprisingly, by the limited number of distinct "useful" DNA sequences that prohibit subunits with nonspecific binding. For our 11 base "sticky ends," the limit is 73 distinct sequences with no unwanted overlaps of 5 bp or more. As an example of phenomena enabled by polygamous particles, we demonstrate a three-particle system that forms a fluid of isolated clusters when cooled slowly and an elastic gel network when quenched.

    We present a simple method to control the position of ellipsoidal magnetic particles in microchannel Poiseuille flow at low Reynolds number using a static uniform magnetic field. The magnetic field is utilized to pin the particle orientation, and the hydrodynamic interactions between ellipsoids and channel walls allow control of the transverse position of the particles. We employ a far-field hydrodynamic theory and simulations using the boundary element method and Brownian dynamics to show how magnetic particles can be focused and segregated by size and shape. This is of importance for particle manipulation in lab-on-a-chip devices.

    In this exploratory qualitative study, we describe instructors' self-reported practices for teaching and assessing students' ability to troubleshoot in electronics lab courses. We collected audio data from interviews with 20 electronics instructors from 18 institutions that varied by size, selectivity, and other factors. In addition to describing participants' instructional practices, we characterize their perceptions about the role of troubleshooting in electronics, the importance of the ability to troubleshoot more generally, and what it means for students to be competent troubleshooters. One major finding of this work is that, while almost all instructors in our study said that troubleshooting is an important learning outcome for students in electronics lab courses, only half of instructors said they directly assessed students' ability to troubleshoot. Based on our findings, we argue that there is a need for research-based instructional materials that attend to both cognitive and non-cognitive aspects of t...

    A general overview of the Jefferson Lab data acquisition run control system is presented. This run control system is designed to operate the configuration, control, and monitoring of all Jefferson Lab experiments. It controls data-taking activities by coordinating the operation of DAQ sub-systems, online software components and third-party software such as external slow control systems. The main, unique feature which sets this system apart from conventional systems is its incorporation of intelligent agent concepts. Intelligent agents are autonomous programs which interact with each other through certain protocols on a peer-to-peer level. In this case, the protocols and standards used come from the domain-independent Foundation for Intelligent Physical Agents (FIPA), and the implementation used is the Java Agent Development Framework (JADE). A lightweight, XML/RDF-based language was developed to standardize the description of the run control system for configuration purposes.

    Lab-on-a-chip multiplex assays allow a rapid identification of multiple parameters in an automated manner. Here we describe a lab-based preparation followed by a rapid and fully automated DNA microarray hybridization and readout in less than 10 min using the Fraunhofer in vitro diagnostics (ivD) platform to enable rapid identification of bacterial species and detection of antibiotic resistance. The use of DNA microarrays allows a fast adaptation of new biomarkers enabling the identification of different genes as well as single-nucleotide-polymorphisms (SNPs) within these genes. In this protocol we describe a DNA microarray developed for identification of Staphylococcus aureus and the mecA resistance gene.

    We present a database containing both the combined photometric object catalog and the single epoch measurements from the Panchromatic Hubble Andromeda Treasury (PHAT). This database is hosted by the NOAO Data Lab (http://datalab.noao.edu), and as such exposes a number of data services to the PHAT photometry, including access through a Table Access Protocol (TAP) service, direct PostgreSQL queries, web-based and programmatic query interfaces, remote storage space for personal database tables and files, and a JupyterHub-based Notebook analysis environment, as well as image access through a Simple Image Access (SIA) service. We show how the Data Lab database and Jupyter Notebook environment allow for straightforward and efficient analyses of PHAT catalog data, including maps of object density, depth, and color, extraction of light curves of variable objects, and proper motion exploration.

    Heiles, C.

    1998-12-01

    We currently offer three advanced laboratory courses for undergraduate majors: optical, IR, and radio. These courses contain both intellectual and practical content; in this talk we focus on the radio lab as a representative example. The first half of the semester concentrates on fundamentals of microwave electronics and radio astronomy techniques in four formal laboratory exercises which emphasize hands-on use of microwave devices, laboratory instruments, and computer-controlled data taking. The second half of the course emphasizes astronomy, using a horn with ~ 1 m(2) aperture to map the HI in the Galaxy and a two-element interferometer composed of ~ 1 m diameter dishes on a ~ 10 m baseline to measure accurate positions of radio sources and accurate diameters for the Sun and Moon. These experiments and observations offer ideal opportunities for teaching coordinates, time, rotation matrices, data reduction techniques, least squares, signal processing, image processing, Fourier transforms, and laboratory and astronomical instrumentation. The students can't get along without using computers as actually used by astronomers. We stay away from packaged software such as IRAF, which are ``black boxes''; rather, students learn far more by writing their own software, usually for the first time. They use the IDL language to take and reduce data and prepare them for the lab reports. We insist on quality reports---including tables, postscript graphs and images, correct grammar, spelling, and all the rest---and we strongly urge (successfully!) the students to use LATEX. The other two lab courses have the same emphasis: the guiding spirit is to place the students in a real-life research-like situation. There is too much to do, so students perform the work in small groups of 3 or 4 and groups are encouraged to share their knowledge. Lab reports are written individually. These courses are very demanding, requiring an average of 20 hours per week from the students (and probably

But the National Physical Laboratory (NPL), which develops and maintains the country's measurement standards, was in fact founded in 1900 to promote links between science and commerce. That tradition, which saw staff at the lab also inventing radar, early computers and modern network packet switching, is something that John Pethica - NPL's new chief scientist - is keen to build on.

    2011-07-01

    Full Text Available The European project is facing a crisis. Citizens no longer understand what the EU is about. Young people and the new ruling class have forgotten the clear message of the European project launched just after the Second World War "No wars ever again among Europeans." The founding fathers of the European Union are mentioned in history textbooks, but today Europe is felt as an irritating bureaucracy. In Europe, peace and economic stability are considered as a natural state, a gift from above. Why keep a useless EU alive? The state of the European Union is swiftly degenerating. In almost all the member states, the anti-European forces are gaining ground. Populism is not a new ideology and is not necessarily European: let's recall Peronism. In today's Europe populism is the new manifestation of nationalism. In Italy the Lega Nord is in Berlusconi's eurosceptic government. In France, the National Front is endangering UMP's hegemony. In Belgium the rows between the Flemish and the Walloons threatens the state's unity. In the Netherlands, Hungary, the Czech Republic, Austria and Finland, populist forces are either in the government or strongly influencing the government. National-populism is different from the nationalism of the past. De Gaulle's nationalism was an ideology founded on the "grandeur" of France's history and on a certain idea of Europe, which was "l'Europe de patrie", a kind of European unity accepting French leadership in world politics. Today national-populism is a form of micro-nationalism: it opposes the European project but without having a serious alternative. This is why populism is dangerous. Its real goal is not only the breaking down of the European Union but also the disintegration of the old nation states into micro-ethnic states, as what happened in former Yugoslavia.

    The Laboratório de Aceleradores e Tecnologias de Radiação (LATR) at the Campus Tecnológico e Nuclear, of Instituto Superior Técnico (IST) has a horizontal electrostatic particle accelerator based on the Van de Graaff machine which is used for research in the area of material characterization. This machine produces alfa (He+) and proton (H+) beams of some μA currents up to 2 MeV/q energies. Beam focusing is obtained using a cylindrical lens of the Einzel type, assembled near the high voltage terminal. This paper describes the developed system that automatically focuses the ion beam, using a personal computer running the LabVIEW software, a multifunction input/output board and signal conditioning circuits. The focusing procedure consists of a scanning method to find the lens bias voltage which maximizes the beam current measured on a beam stopper target, which is used as feedback for the scanning cycle. This system, as part of a wider start up and shut down automation system built for this particle accelerator, brings great advantages to the operation of the accelerator by turning it faster and easier to operate, requiring less human presence, and adding the possibility of total remote control in safe conditions.

  11. Emittance Measurements of the Jefferson Lab Free Electron Laser using optical transition radiation

    Energy Technology Data Exchange (ETDEWEB)

    Holloway, Michael Andrew [Univ. of Maryland, College Park, MD (United States)

    2007-05-01

    Charged particle accelerators, such as the ones that power Free Electron Lasers (FEL), require high quality (low emittance) beams for efficient operation. Accurate and reliable beam diagnostics are essential to monitoring beam parameters in order to maintain a high quality beam. Optical Transition Radiation Interferometry (OTRI) has shown potential to be a quality diagnostic that is especially useful for high brightness electron beams such as Jefferson Labs FEL energy recovery linac. The purpose of this project is to further develop OTRI beam diagnostic techniques. An optical system was designed to make beam size and divergence measurements as well as to prepare for experiments in optical phase space mapping. Beam size and beam divergence measurements were taken to calculate the emittance of the Jefferson Lab FEL. OTRI is also used to separate core and halo beam divergences in order to estimate core and halo emittance separately.

    An approach employing ultrafast laser hybrid microfabrication combining ablation, 3D nanolithography and welding is proposed for the realization of Lab-On-Chip (LOC) device. The same laser setup is shown to be suitable for fabricating microgrooves in glass slabs, polymerization of fine meshes inside them, and, lastly, sealing the whole chip with cover glass into one monolithic piece. The created micro fluidic device proved its particle sorting function by separating 1 μm and 10 μm polystyrene spheres from a mixture. Next, a lens adapter for a cell phone's camera was manufactured via thermal extrusion 3D printing technique which allowed to achieve sufficient magnification to clearly resolve <10 μm features. All together shows fs-laser microfabrication technology as a flexible and versatile tool for study and manufacturing of Lab-On-Chip devices.

    The problems concerning the aurora posed prior to the war are now either solved in principle or were restated in a more fundamental form. The pre-war hypothesis concerning the nature of the auroral particles and their energies was fully confirmed, with the exception that helium and oxygen ions were identified as participating in the auroral particle precipitation in addition to the protons. The nature of the near-Earth energization processes affecting auroral particles was clarified. Charged particle trajectories in various electric field geometries were modeled. The physical problems have now moved from determining the nature and geometry of the electric fields, which accelerate charged particles near the Earth, to accounting for the existence of these electric fields as a natural consequence of the solar wind's interaction with Earth. Ultimately the reward in continuing the work in auroral and magnetospheric particle dynamics will be a deeper understanding of the subtleties of classical electricity and magnetism as applied to situations not blessed with well-defined and invariant geometries.

    2016-03-01

    The miniaturization, rapid prototyping and automation of lab-on-a-chip technology play nowadays a very important role. Lab-on-a-chip technology is successfully implemented not only for environmental analysis and medical diagnostics, but also as replacement of animals used for the testing of substances in the pharmaceutical and cosmetics industries. For that purpose the Fraunhofer IWS and partners developed a lab-on-a-chip platform for perfused cell-based assays in the last years, which includes different micropumps, valves, channels, reservoirs and customized cell culture modules. This technology is already implemented for the characterization of different human cell cultures and organoids, like skin, liver, endothelium, hair follicle and nephron. The advanced universal lab-on-a-chip platform for complex, perfused 3D cell cultures is divided into a multilayer basic chip with integrated micropump and application-specific 3D printed cell culture modules. Moreover a technology for surface modification of the printed cell culture modules by laser micro structuring and a complex and flexibly programmable controlling device based on an embedded Linux system was developed. A universal lab-on-a-chip platform with an optional oxygenator and a cell culture module for cubic scaffolds as well as first cell culture experiments within the cell culture device will be presented. The module is designed for direct interaction with robotic dispenser systems. This offers the opportunity to combine direct organ printing of cells and scaffolds with the microfluidic cell culture module. The characterization of the developed system was done by means of Micro-Particle Image Velocimetry (μPIV) and an optical oxygen measuring system.

    2016-01-01

    the success teachers have had providing an opportunity for students to: • Organize and conduct authentic research. • Experience the environment of scientific collaborations. • Possibly make real contributions to a burgeoning scientific field. We've created projects that are problem-based, student driven and technology dependent. Students reach beyond classroom walls to explore data with other students and experts and share results, publishing original work to a worldwide audience. Students can discover and extend the research of other students, modeling the processes of modern, large-scale research projects. From start to finish e-Labs are student-led, teacher-guided projects. Students need only a Web browser to access computing techniques employed by professional researchers. A Project Map with milestones allows students to set the research plan rather than follow a step-by-step process common in other online projects. Most importantly, e-Labs build the learning experience around the students' own questions and let them use the very tools that scientists use. Students contribute to and access shared data, most derived from professional research databases. They use common analysis tools, store their work and use metadata to discover, replicate and confirm the research of others. This is where real scientific collaboration begins. Using online tools, students correspond with other research groups, post comments and questions, prepare summary reports, and in general participate in the part of scientific research that is often left out of classroom experiments. Teaching tools such as student and teacher logbooks, pre- and post-tests and an assessment rubric aligned with learner outcomes help teachers guide student work. Constraints on interface designs and administrative tools such as registration databases give teachers the "one-stop-shopping" they seek for multiple e-Labs. Teaching and administrative tools also allow us to track usage and assess the

    The duality between the partonic and hadronic descriptions of electron--nucleon scattering is a remarkable feature of nuclear interactions. When averaged over appropriate energy intervals the cross section at low energy which is dominated by nucleon resonances resembles the smooth behavior expected from perturbative QCD. Recent Jefferson Lab results indicate that quark-hadron duality is present in a variety of observables, not just the proton F2 structure function. An overview of recent results, especially local quark-hadron duality on the neutron, are presented here.

    Measuring voltage-current and voltage-power curves of a photovoltaic module is a nice experiment for high school and undergraduate students. In labs where real sunlight is not available this experiment requires a solar simulator. A prototype of a simulator using LED lamps has been manufactured and tested, and a comparison with classical halogen simulators has been performed. It is found that LED light offers lower levels of irradiance, but much better performance in terms of module output for a given irradiance.

The measurement has been developed in LabView environment using National Instrument Data Acquisition Cards. The measurement technique of symmetric minor loops and first-order reversal curves are presented. It is necessary to measure the magnetic hysteresis curves of ferromagnetic material to describe the material from magnetic point of view. The measured scalar hysteresis characteristics taking into account the nonlinearity of the material can be used in further simulations in numerical field computations.

    Full Text Available Two studies investigated the effectiveness of teaching science labs online to secondary students. Study 1 compared achievement among students instructed using hands-on Chemistry labs versus those instructed using virtual Chemistry labs (eLabs. Study 2 compared the same groups of students again while both teachers instructed using hands-on Chemistry labs to determine whether teacher or student characteristics may have affected Study 1’s findings. Participants were high school Chemistry students from a Central Texas Independent School District. Results indicated that: students learn science effectively online, schools may experience cost savings from delivering labs online, and students gain valuable technology skills needed later in college and in the workplace.

    Release of volcanic ash into the atmosphere poses a significant hazard to air traffic. Exposure to appreciable concentrations (≥4 mg m-3) of ash can result in engine shutdown, air data system loss, and airframe damage, with sustained lower concentrations potentially causing other long-term detrimental effects [1]. Disruption to flights also has a societal impact. For example, the closure of European airspace following the 2010 eruption of Eyjafjallajökull resulted in global airline industry losses of order £1100 million daily and disruption to 10 million passengers. Accurate and effective measurement of the mass of ash in a volcanic plume along with in situ characterisation of other plume properties such as charge, turbulence, and SO2 concentration can be used in combination with plume dispersion modelling, remote sensing, and more sophisticated flight ban thresholds to mitigate the impact of future events. VolcLab is a disposable instrument package that may be attached to a standard commercial radiosonde, for rapid emergency deployment on a weather balloon platform. The payload includes a newly developed gravimetric sensor using the oscillating microbalance principle to measure mass directly without assumptions about particles' optical properties. The package also includes an SO2 gas detector, an optical sensor to detect ash and cloud backscatter from an LED source [2], a charge sensor to characterise electrical properties of the plume [3], and an accelerometer to measure in-plume turbulence [4]. VolcLab uses the established PANDORA interface [5], to provide data exchange and power from the radiosonde. In addition to the VolcLab measurements, the radiosonde provides standard meteorological data of temperature, pressure, and relative humidity, and GPS location. There are several benefits of using this instrument suite in this design and of using this method of deployment. Firstly, this is an all-in-one device requiring minimal expertise on the part of the end

    2002-01-01

    The Black Hills of South Dakota exhibits many fine examples of stream piracy that are very suitable for teaching geomorphology lab exercises. This lab goes beyond standard topographic map interpretation by using geologic maps, well logs, gravel provenance and other types of data to teach students about stream piracy. Using a step-by-step method in which the lab exercises ramp up in difficulty, students hone their skills in deductive reasoning and data assimilation. The first exercises deal with the identification of stream piracy at a variety of spatial scales and the lab culminates with an exercise on landscape evolution and drainage rearrangement.

    Interventional cardiologists act as leaders every time they step into a catheterization laboratory (cath lab), but leadership training is rarely included in cardiology training programs. Cath lab physicians should cultivate and practice effective leadership skills. Specifically, (1) before each procedure assess whether the cath lab team is prepared; (2) delegate authority to trainees and team members when appropriate; (3) use every procedure to improve the performance of team members through teaching, coaching, and mentorship; (4) debrief the team after adverse events; (5) develop the traits, styles, and skills associated with successful leadership; and (6) provide team training for the cath lab team.

    It can be challenging to interface National Instruments LabVIEW (http://www.ni.com/labview/) with EPICS (http://www.aps.anl.gov/epics/). Such interface is required when an instrument control program was developed in LabVIEW but it also has to be part of global control system. This is frequently useful in big accelerator facilities. The Channel Access Server is written in LabVIEW, so it works on any hardware/software platform where LabVIEW is available. It provides full server functionality, so any EPICS client can communicate with it.

    Over the last 80 years, Bell Labs has been one of the most scientifically and technologically productive research labs in the world. Inventions such as the transistor, laser, cell phone, solar cell, negative feedback amplifier, communications satellite and many others were made there. Scientific breakthroughs such as discovery of the Big Bang, the wave nature of the electron, electron localization and the fractional quantum hall effect were also made there making Bell Labs almost unique in terms of large impacts in both science and technology. In my talk, I will discuss the history of the lab, talk about the present and give some suggestions for how I see it evolving into the future.

    Separation of cells is a key application area of lab-on-a-chip (LOC) devices. Among the various methods, magnetic separation of cells utilizing microfluidic devices offers the merits of biocompatibility, efficiency, and simplicity. This review discusses the fundamental physics involved in using magnetic force to separate particles, and identifies the optimisation parameters and corresponding methods for increasing the magnetic force. The paper then elaborates the design considerations of LOC devices for continuous-flow magnetic cell separation. Examples from the recently published literature illustrate these state-of-the-art techniques.

    We present design criteria, operation principles and experimental examples of magnetic marker manipulation for our magnetic lab-on-a-chip prototype. It incorporates both magnetic sample preparation and detection by embedded GMR-type magnetoresistive sensors and is optimized for the automated point-of-care detection of four different sepsis-indicative cytokines directly from about 5 {mu}l of whole blood. The sample volume, magnetic particle size and cytokine concentration determine the microfluidic volume, sensor size and dimensioning of the magnetic gradient field generators. By optimizing these parameters to the specific diagnostic task, best performance is expected with respect to sensitivity, analysis time and reproducibility.

    The EarthLabs project provides a framework to enhance high school students' climate literacy and awareness of climate change. The project provides climate science curriculum and teacher professional development, followed by research on students' learning as teachers implement EarthLabs climate modules in the classroom. The professional development targets high school teachers whose professional growth is structured around exposure to current climate science research, data observation collection and analysis. During summer workshops in Texas and Mississippi, teachers work through the laboratories, experiments, and hand-on activities developed for their students. In summer 2013, three graduate students from the University of Texas at Austin Institute for Geophysics with expertise in climate science participated in two weeklong workshops. The graduate students partnered with exemplary teacher leaders to provide scientific content and lead the EarthLabs learning activities. As an experiment, we integrated a visit to the Blanton Museum and an associated activity in order to motivate participants to think creatively, as well as analytically, about science. This exercise was inspired by the work and educational philosophy of Sister Corita Kent. During the visit to the Blanton Museum, we steered participants towards specific works of art pre-selected to emphasize aspects of the climate of Texas and to draw participants' attention to ways in which artists convey different concepts. For example, artists use of color, lines, and symbols conjure emotional responses to imagery in the viewer. The second part of the exercise asked participants to choose a climate message and to convey this through a collage. We encouraged participants to combine their experience at the museum with examples of Sister Corita Kent's artwork. We gave them simple guidelines for the project based on techniques and teaching of Sister Corita Kent. Evaluation results reveal that participants enjoyed the

"Scientists across Europe, including those in EIROforum labs, are continually making discoveries that they would be willing and able to explain to young people, but there's no central mechanism to help do so - we think that this new journal can help fulfil that function." "Motivating more young people to take an interest in understanding and learning science at school is important not only because science careers are exciting and rewarding, but also because young people need to know about how science and technology is changing our world - their world!," says Stephen Parker, Head of Education and Science of the European Commission. "Science in School is just one of the initiatives being supported by the Commission to take this forward." EIROforum sustains many other education activities including the Science on Stage festival, a sort of European teaching Olympics where teachers present their most inventive methods. The best projects from last year's Science on Stage festival will be featured in Science in School.

    Every freshman entering Rose-Hulman Institute of Technology is equipped with a laptop computer and a software package that allow classroom and laboratory instructors the freedom to make computer-based assignments, publish course materials in electronic form, etc. All introductory physics laboratories and many of our classrooms are networked, and students routinely take their laptop computers to class/lab. The introductory physics laboratory manual was converted to HTML in the summer of 1997 and was made available to students over the Internet vice printing a paper manual during the 1998-99 school year. The aim was to reduce paper costs and allow timely updates of the laboratory experiments. A poll conducted at the end of the school year showed a generally positive student response to the online laboratory manual, with some reservations.

  5. Making the Case for Jefferson Lab

    This chapter is a personal account of the initial planning and competition for a new laboratory, which eventually became known as the Thomas Jefferson National Accelerator Facility, with the official nickname "Jefferson Lab." The period covered starts as far back as 1964, with the introduction of quarks, and extends up to the late 1980s after the initial team was assembled, the superconducting design was in place, and construction was well underway. I describe some of the major experiments that were proposed to justify the laboratory, reflect on the present status of those initially proposed experiments, and very briefly outline some of the new ideas that emerged after the laboratory was constructed. The science is presented in a simple manner intended for a lay audience, with some of the ideas illustrated by cartoons that were often used in popular lectures given during this period.

    A frozen spin polarized target, constructed at Jefferson Lab for use inside a large acceptance spectrometer, is described. The target has been utilized for photoproduction measurements with polarized tagged photons of both longitudinal and circular polarization. Protons in TEMPO-doped butanol were dynamically polarized to approximately 90% outside the spectrometer at 5 T and 200-300 mK. Photoproduction data were acquired with the target inside the spectrometer at a frozen-spin temperature of approximately 30 mK with the polarization maintained by a thin, superconducting coil installed inside the target cryostat. A 0.56 T solenoid was used for longitudinal target polarization and a 0.50 T dipole for transverse polarization. Spin relaxation times as high as 4000 hours were observed. We also report polarization results for deuterated propanediol doped with the trityl radical OX063.

    The Wells Fargo Innovation Incubator (IN2) is a program to foster and accelerate startup companies with commercial building energy-efficiency and demand management technologies. The program is funded by the Wells Fargo Foundation and co-administered by the National Renewable Energy Laboratory (NREL). Whisker Labs, an Oakland, California-based company, was one of four awardees in the first IN2 cohort and was invited to participate in the program because of its novel electrical power sensing technology for circuit breakers. The stick-on Whisker meters install directly on the front face of the circuit breakers in an electrical panel using adhesive, eliminating the need to open the panel and install current transducers (CTs) on the circuit wiring.

  8. Replacing textbook problems with lab experiences

    Register, Trevor

    2017-10-01

    End-of-the-chapter textbook problems are often the bread and butter of any traditional physics classroom. However, research strongly suggests that students be given the opportunity to apply their knowledge in multiple contexts as well as be provided with opportunities to do the process of science through laboratory experiences. Little correlation has been shown linking the number of textbook problems solved with conceptual understanding of topics in mechanics. Furthermore, textbook problems as the primary source of practice for students robs them of the joy and productive struggle of learning how to think like an experimental physicist. Methods such as Modeling Instruction tackle this problem head-on by starting each instructional unit with an inquiry-based lab aimed at establishing the important concepts and equations for the unit, and this article will discuss ideas and experiences for how to carry that philosophy throughout a unit.

    Jefferson Lab has designed, built and operated two high average power free-electron lasers (FEL) using superconducting RF (SRF) technology and energy recovery techniques. Between 1999-2001 Jefferson Lab operated the IR Demo FEL. This device produced over 2 kW in the mid-infrared, in addition to producing world record average powers in the visible (50 W), ultraviolet (10 W) and terahertz range (50 W) for tunable, short-pulse (< ps) light. This FEL was the first high power demonstration of an accelerator configuration that is being exploited for a number of new accelerator-driven light source facilities that are currently under design or construction. The driver accelerator for the IR Demo FEL uses an Energy Recovered Linac (ERL) configuration that improves the energy efficiency and lowers both the capital and operating cost of such devices by recovering most of the power in the spent electron beam after optical power is extracted from the beam. The IR Demo FEL was de-commissioned in late 2001 for an upgraded FEL for extending the IR power to over 10 kW and the ultraviolet power to over 1 kW. The FEL Upgrade achieved 10 kW of average power in the mid-IR (6 microns) in July of 2004, and its IR operation currently is being extended down to 1 micron. In addition, we have demonstrated the capability of on/off cycling and recovering over a megawatt of electron beam power without diminishing machine performance. A complementary UV FEL will come on-line within the next year. This paper presents a summary of the FEL characteristics, user community accomplishments with the IR Demo, and planned user experiments.

    Full Text Available In the early 2000s, the expectations about bacteriocins produced by lactic acid bacteria (LABs were aimed at food applications. However, the effectiveness of bacteriocins against undesirable micro-organisms opened endless possibilities for innovative research. In the present review, we collected a database including 429 published papers and 245 granted patents (from 2004 to 2015. Based on bibliometric analysis, the progress of bacteriocin research in the last 11 years was discussed in detail. It was found that 164 patents were granted in 2010–2015, which is equivalent to 60% in comparison with previous years (i.e. only 81 patents were granted in 2004–2009. Currently, the research on bacteriocins is still gaining importance. In the realm of therapeutic strategies, about a 37% of the published research was focused on biomedical applications in the last decade. This vein of research is currently seeking for alternative solutions to problems such as cancer, systemic infections, oral-care, vaginal infections, contraception and skincare. On the other hand, food preservation, bio-nanomaterial and veterinary applications represent 29%, 25% and 9%, respectively. All this technology is being applied and will surely grow in the future, since about 31% of the patents granted since 2004 are focused on the biomedical area, 29% on food preservation, 5% on veterinary use; whereas 13% and 16% correspond to patents granted on production–purification systems and recombinant proteins or molecular modifications in the producer strains. This review contributes to the analysis of recent LAB bacteriocin applications and their role in safety, quality and improvement of human health.

    To reduce unnecessary lab testing by predicting when a proposed future lab test is likely to contribute information gain and thereby influence clinical management in patients with gastrointestinal bleeding. Recent studies have demonstrated that frequent laboratory testing does not necessarily relate to better outcomes. Data preprocessing, feature selection, and classification were performed and an artificial intelligence tool, fuzzy modeling, was used to identify lab tests that do not contribute an information gain. There were 11 input variables in total. Ten of these were derived from bedside monitor trends heart rate, oxygen saturation, respiratory rate, temperature, blood pressure, and urine collections, as well as infusion products and transfusions. The final input variable was a previous value from one of the eight lab tests being predicted: calcium, PTT, hematocrit, fibrinogen, lactate, platelets, INR and hemoglobin. The outcome for each test was a binary framework defining whether a test result contributed information gain or not. Predictive modeling was applied to recognize unnecessary lab tests in a real world ICU database extract comprising 746 patients with gastrointestinal bleeding. Classification accuracy of necessary and unnecessary lab tests of greater than 80% was achieved for all eight lab tests. Sensitivity and specificity were satisfactory for all the outcomes. An average reduction of 50% of the lab tests was obtained. This is an improvement from previously reported similar studies with average performance 37% by [1-3]. Reducing frequent lab testing and the potential clinical and financial implications are an important issue in intensive care. In this work we present an artificial intelligence method to predict the benefit of proposed future laboratory tests. Using ICU data from 746 patients with gastrointestinal bleeding, and eleven measurements, we demonstrate high accuracy in predicting the likely information to be gained from proposed future

    Lab-on-a-chip technology is an emerging field evolving from the recent advances of micro- and nanotechnologies. The technology allows the integration of various components into a single microdevice. Microfluidics, the science and engineering of fluid flow in microscale, is the enabling underlying concept for lab-on-a-chip technology. The present paper reviews the design, fabrication and characterization of drug delivery systems based on this amazing technology. The systems are categorized and discussed according to the scales at which the drug is administered. Starting with the fundamentals on scaling laws of mass transfer and basic fabrication techniques, the paper reviews and discusses drug delivery devices for cellular, tissue and organism levels. At the cellular level, a concentration gradient generator integrated with a cell culture platform is the main drug delivery scheme of interest. At the tissue level, the synthesis of smart particles as drug carriers using lab-on-a-chip technology is the main focus of recent developments. At the organism level, microneedles and implantable devices with fluid-handling components are the main drug delivery systems. For drug delivery to a small organism that can fit into a microchip, devices similar to those of cellular level can be used. Copyright © 2013 Elsevier B.V. All rights reserved.

    Plasma-based acceleration techniques are of great interest for future, compact accelerators due to their high accelerating gradient. Both particle-driven and laser-driven Plasma Wakefield Acceleration experiments are foreseen at the SPARC-LAB Test Facility (INFN National Laboratories of Frascati, Italy), with the aim to accelerate high-brightness electron beams. In order to optimize the efficiency of the acceleration in the plasma and preserve the quality of the accelerated beam, the knowledge of the plasma electron density is mandatory. The Stark broadening of the Hydrogen spectral lines is one of the candidates used to characterize plasma density. The implementation of this diagnostic for plasma-based experiments at SPARC-LAB is presented. - Highlights: • Stark broadening of Hydrogen lines has been measured to determine plasma density. • Plasma density diagnostic tool for plasma-based experiments at SPARC-LAB is presented. • Plasma density in tapered laser triggered ablative capillary discharge was measured. • Results of plasma density measurements in ablative capillaries are shown.

    The high energy physics group at the University of South Carolina, under the leadership of Profs. S.R. Mishra, R. Petti, M.V. Purohit, J.R. Wilson (co-PI's), and C. Rosenfeld (PI), engaged in studies in "Experimental Particle Physics." The group collaborated with similar groups at other universities and at national laboratories to conduct experimental studies of elementary particle properties. We utilized the particle accelerators at the Fermi National Accelerator Laboratory (Fermilab) in Illinois, the Stanford Linear Accelerator Center (SLAC) in California, and the European Center for Nuclear Research (CERN) in Switzerland. Mishra, Rosenfeld, and Petti worked predominantly on neutrino experiments. Experiments conducted in the last fifteen years that used cosmic rays and the core of the sun as a source of neutrinos showed conclusively that, contrary to the former conventional wisdom, the "flavor" of a neutrino is not immutable. A neutrino of flavor "e," "mu," or "tau," as determined from its provenance, may swap its identity with one of the other flavors -- in our jargon, they "oscillate." The oscillation phenomenon is extraordinarily difficult to study because neutrino interactions with our instruments are exceedingly rare -- they travel through the earth mostly unimpeded -- and because they must travel great distances before a substantial proportion have made the identity swap. Three of the experiments that we worked on, MINOS, NOvA, and LBNE utilize a beam of neutrinos from an accelerator at Fermilab to determine the parameters governing the oscillation. Two other experiments that we worked on, NOMAD and MIPP, provide measurements supportive of the oscillation experiments. Good measurements of the neutrino oscillation parameters may constitute a "low energy window" on related phenomena that are otherwise unobservable because they would occur only at energies way above the reach of conceivable accelerators. Purohit and Wilson participated in the Ba

    2013-05-01

    Full Text Available Embedded systems play vital role in modern applications [1]. They can be found in autos, washing machines, electrical appliances and even in toys. FPGAs are the most recent computing technology that is used in embedded systems. There is an increasing demand on FPGA based embedded systems, in particular, for applications that require rapid time responses. Engineering education curricula needs to respond to the increasing industrial demand of using FPGAs by introducing new syllabus for teaching and learning this subject. This paper describes the development of new course material for teaching FPGA-based embedded systems design by using ‘G’ Programming Language of LabVIEW. A general overview of FPGA role in engineering education is provided. A survey of available Hardware Programming Languages for FPGAs is presented. A survey about LabVIEW utilization in engineering education is investigated; this is followed by a motivation section of why to use LabVIEW graphical programming in teaching and its capabilities. Then, a section of choosing a suitable kit for the course is laid down. Later, constructivist closed-loop model the FPGA course has been proposed in accordance with [2-4; 80,86,89,92]. The paper is proposing a pedagogical framework for FPGA teaching; pedagogical evaluation will be conducted in future studies. The complete study has been done at the Faculty of Electrical and Electronic Engineering, Aleppo University.

  13. Structuring User Involvement in Panel-Based Living Labs

    2012-09-01

    Full Text Available A shift towards open innovation approaches with systematic user involvement has occurred within media and ICT. One of the emerging frameworks structuring these initiatives is the "living lab" approach. Despite the growing evidence of the beneficial nature of customer involvement in product development, research into specific user characteristics for innovation is still scarce, particularly in living labs, with the notable exception of literature on lead users. Especially within the context of living labs for ICT and media innovation, an application of the lead-user framework looks promising as a way to structure and facilitate user involvement. This article is based on the experiences of three Flemish living lab initiatives with a panel-based approach and provides a customer characteristics framework that guides user involvement in living labs.

    2004-11-09

    We describe a new aerogel threshold Cherenkov detector installed in the HMS spectrometer in Hall C at Jefferson Lab. The Hall C experimental program in 2003 required an improved particle identification system for better identification of {pi}/K/p, which was achieved by installing an additional threshold Cherenkov counter. Two types of aerogel with n = 1.03 and n = 1.015 allow one to reach {approx}10{sup -3} proton and 10{sup -2} kaon rejection in the 1-5 GeV/c momentum range with pion detection efficiency better than 99% (97%). The detector response shows no significant position dependence due to a diffuse light collection technique. The diffusion box was equipped with 16 Photonis XP4572 PMT's. The mean number of photoelectrons in saturation was {approx}16 and {approx}8, respectively. Moderate particle identification is feasible near threshold.

    2013-01-01

    First of all, my thanks to the Nobel Lindau Foundation for their inspiration and leadership in sharing the excitement of scientific discovery with the public and with future scientists! I have had the pleasure of participating twice in the Lindau meetings, and recently worked with the Nobel Labs 360 project to show how we are building the world's greatest telescope yet, the James Webb Space Telescope (JWST). For the future, I see the greatest challenges for all the sciences in continued public outreach and inspiration. Outreach, so the public knows why we are doing what we are doing, and what difference it makes for them today and in the long-term future. Who knows what our destiny may be? It could be glorious, or not, depending on how we all behave. Inspiration, so that the most creative and inquisitive minds can pursue the scientific and engineering discoveries that are at the heart of so much of human prosperity, health, and progress. And, of course, national and local security depend on those discoveries too; scientists have been working with "the government" throughout recorded history. For the Lindau Nobel experiment, we have a truly abundant supply of knowledge and excitement, through the interactions of young scientists with the Nobelists, and through the lectures and the video recordings we can now share with the whole world across the Internet. But the challenge is always to draw attention! With 7 billion inhabitants on Earth, trying to earn a living and have some fun, there are plenty of competing opportunities and demands on us all. So what will draw attention to our efforts at Lindau? These days, word of mouth has become word of (computer) mouse, and ideas propagate as viruses ( or memes) across the Internet according to the interests of the participants. So our challenge is to find and match those interests, so that the efforts of our scientists, photographers, moviemakers, and writers are rewarded by our public. The world changes every day, so there

  1. Designing virtual science labs for the Islamic Academy of Delaware

    Science.gov (United States)

    AlZahrani, Nada Saeed

    Science education is a basic part of the curriculum in modern day classrooms. Instructional approaches to science education can take many forms but hands-on application of theory via science laboratory activities for the learner is common. Not all schools have the resources to provide the laboratory environment necessary for hands-on application of science theory. Some settings rely on technology to provide a virtual laboratory experience instead. The Islamic Academy of Delaware (IAD), a typical community-based organization, was formed to support and meet the essential needs of the Muslim community of Delaware. IAD provides science education as part of the overall curriculum, but cannot provide laboratory activities as part of the science program. Virtual science labs may be a successful model for students at IAD. This study was conducted to investigate the potential of implementing virtual science labs at IAD and to develop an implementation plan for integrating the virtual labs. The literature has shown us that the lab experience is a valuable part of the science curriculum (NBPTS, 2013, Wolf, 2010, National Research Council, 1997 & 2012). The National Research Council (2012) stressed the inclusion of laboratory investigations in the science curriculum. The literature also supports the use of virtual labs as an effective substitute for classroom labs (Babateen, 2011; National Science Teachers Association, 2008). Pyatt and Simms (2011) found evidence that virtual labs were as good, if not better than physical lab experiences in some respects. Although not identical in experience to a live lab, the virtual lab has been shown to provide the student with an effective laboratory experience in situations where the live lab is not possible. The results of the IAD teacher interviews indicate that the teachers are well-prepared for, and supportive of, the implementation of virtual labs to improve the science education curriculum. The investigator believes that with the

    2014-10-01

    Semi-inclusive deep inelastic scattering (SIDIS) has been used extensively in recent years as an important testing ground for QCD. Studies so far have concentrated on better determination of parton distribution functions, distinguishing between the quark and antiquark contributions, and understanding the fragmentation of quarks into hadrons. Hadron pair (di-hadron) SIDIS provides information on the nucleon structure and hadronization dynamics that complement single hadron SIDIS. Di-hadrons allow the study of low- and high-twist distribution functions and Dihadron Fragmentation Functions (DiFF). Together with the twist-2 PDFs ( f1, g1, h1), the Higher Twist (HT) e and hL functions are very interesting because they offer insights into the physics of the largely unexplored quark-gluon correlations, which provide access into the dynamics inside hadrons. The CLAS spectrometer, installed in Hall-B at Jefferson Lab, has collected data using the CEBAF 6 GeV longitudinally polarized electron beam on longitudinally polarized solid NH3 targets. Preliminary results on di-hadron beam-, target- and double-spin asymmetries will be presented.

    The use of gaming as an educational tool has proven to be an effective paradigm in modern pedagogy. Following the success of their previous work ``Sector Vector,'' the authors present a new interactive game-based laboratory to highlight the basic manipulation and calculation of resistors in circuits. ``Resistance is Futile'' delivers the lesson of basic resistor combinations in a game based exercise where teams build a continually evolving circuit. As the game progresses, students must develop long and short term plans to modify an ever-changing circuit and meet primary and secondary objectives. Each turn requires quick calculations of resistor combinations and the assessment of future options. Students are also exposed to the creation of a modular circuit, which may not conform to standard textbook examples. To determine a winner, the students work together to analyze and evaluate a potentially complex final circuit diagram. The dynamic atmosphere and competitive nature established by the gaming environment have been shown to increase student engagement and concept retention. In this presentation, we will discuss both the structure of the lab-based game and the pedagogical implications this implementation versus the traditional resistor combination laboratory exercise.

    The population alarm systems do not represent a new concept. Since hundreds of years ago the man used either smoke signals generated from certain upper locations, visible from long distance, getting through acoustic systems placed on high buildings, until now when mass-media channels extended the possibilities by the television and radio. However, either one of those mentioned above requested the individual to be located at the alarming moment in the area of action of the alarm. Otherwise, the message has no efficiency. This limitation is currently solved by additional communication channels such as the internet and the mobile networks. Messages are now able to be sent to the mobile screen, and the user can reply to messages either by using the short message service (SMS) or by emailing to someone, to a server, to a center. From the general pattern of alarming the population on certain events, the medical applications represent a very important field. Messages are sent from the patient to a central medical center and back to the patient. This paper focuses on the value that virtual tools developed with LabVIEW brings to us.

  18. AAPT Lab Recommendations: Past, Present, and Future

    Kozminski, Joseph

    The ``AAPT Recommendations for the Undergraduate Physics Laboratory Curriculum'' was endorsed by the American Association of Physics Teachers Executive Board in November 2014. This set of curriculum recommendations focuses on developing skills and competencies that will prepare students for research in graduate school and for jobs in the STEM sector, education, and many other employment sectors. The recommendations can be used to guide changes in laboratory curricula, to assess department laboratory curricula during program reviews, and to educate university officials about the importance of laboratory experiences. The recommendations offer many potential opportunities for collaboration between physics education researchers and laboratory instructors in studying skill development in the lab and how various elements of the laboratory curriculum can best be assessed. There are also discussions underway to create an online resource for laboratory instructors to share implementation ideas and resources. This presentation provides an overview of these recommendations and their development, how the recommendations are currently being used, and opportunities for expanded use of the recommendations going forward.

  19. Featured Image: Making Dust in the Lab

    This remarkable photograph (which spans only 10 m across; click for a full view) reveals what happens when you form dust grains in a laboratory under conditions similar to those of interstellar space. The cosmic life cycle of dust grains is not well understood we know that in the interstellar medium (ISM), dust is destroyed at a higher rate than it is produced by stellar sources. Since the amount of dust in the ISM stays constant, however, there must be additional sources of dust production besides stars. A team of scientists led by Daniele Fulvio (Pontifical Catholic University of Rio de Janeiro and the Max Planck Institute for Astronomy at the Friedrich Schiller University Jena) have now studied formation mechanisms of dust grains in the lab by mimicking low-temperature ISM conditions and exploring how, under these conditions, carbonaceous materials condense from gas phase to form dust grains. To read more about their results and see additional images, check out the paper below.CitationDaniele Fulvio et al 2017 ApJS 233 14. doi:10.3847/1538-4365/aa9224

    2002-05-01

    The history of the Harvard Pigeon Lab is a history of two periods of remarkable productivity, the first under Skinner's leadership and the second under Herrnstein's. In each period, graduate students flocked to the leader and then began stimulating one another. Chance favored Herrnstein's leadership, too, because an unusually large number of graduate students were admitted in the fall of 1962. In each period, productivity declined as the leader lost interest in the laboratory and withdrew. Directly and indirectly, the laboratory finally died as a result of the cognitive "revolution." Skinner and his students saw the possibility of a natural science of behavior and set about establishing that science based on concepts such as response rate, stimulus control, and schedules of reinforcement. Herrnstein and his students saw that the science could be quantitative and set about making it so, with relative response rate, the matching law, and the psychophysics of choice (analogous to S. S. Stevens' psychophysics). The history might provide a golden research opportunity for someone interested in the impact of such self-organizing research groups on the progress of science.

    Collaborative research/computing environments are essential for working with the next generations of large astronomical data sets. A key component of them is a distributed storage system to enable data hosting, sharing, and publication. VOSpace1 is a lightweight interface providing network access to arbitrary backend storage solutions and endorsed by the International Virtual Observatory Alliance (IVOA). Although similar APIs exist, such as Amazon S3, WebDav, and Dropbox, VOSpace is designed to be protocol agnostic, focusing on data control operations, and supports asynchronous and third-party data transfers, thereby minimizing unnecessary data transfers. It also allows arbitrary computations to be triggered as a result of a transfer operation: for example, a file can be automatically ingested into a database when put into an active directory or a data reduction task, such as Sextractor, can be run on it. In this paper, we shall describe the VOSpace implementations that we have developed for the NOAO Data Lab. These offer both dedicated remote storage, accessible as a local file system via FUSE, and a local VOSpace service to easily enable data synchronization.

    Great physics breakthroughs are rarely included in the introductory physics course. General relativity and binary black hole coalescence are no different, and can be included in the introductory course only in a very limited sense. However, we can design activities that directly involve the detection of GW150914, the designation of the Gravitation Wave signal detected on September 14, 2015, thereby engage the students in this exciting discovery directly. The activities naturally do not include the construction of a detector or the detection of gravitational waves. Instead, we design it to include analysis of the data from GW150914, which includes some interesting analysis activities for students of the introductory course. The same activities can be assigned either as a laboratory exercise or as a computational project for the same population of students. The analysis tools used here are simple and available to the intended student population. It does not include the sophisticated analysis tools, which were used by LIGO to carefully analyze the detected signal. However, these simple tools are sufficient to allow the student to get important results. We have successfully assigned this lab project for students of the introductory course with calculus at Georgia Gwinnett College.

  3. Creation of a European network dedicated to technology transfer

    The CERN Council recently approved the creation of a technology transfer network, whose aim will be to improve European industry’s access to the technologies developed by the particle physics community in the Member States. The gas detectors for the TOTEM experiment (GEM) offer potential for fruitful collaboration within the framework of the TT network. Many other technologies are going down the same road.The desire to set up a technology transfer network follows on from the European Strategy for Particle Physics, approved by the CERN Council on 14 July 2006 in Lisbon. In this context, special emphasis was laid on European industry’s participation in the implementation of particle physics programmes and, in particular, its access to the new technologies developed by the scientific community. It was recognised that effort needs to be put into improving the efficiency of technology transfer...

  4. Can Direct Measurement Videos Inspire Lab-like Learning?

    2014-12-01

    Hands-on labs can offer students a rare opportunity to confront the laws of physics first hand and to gain experience using science practices. As such, hands-on labs are an important learning tool which have played a foundational role in science education since the time of Galileo. But labs also have features that make them difficult to implement in practice. They are often time consuming for the instructor to plan and setup, time consuming for students to perform, expensive to implement, and fraught with potential missteps that can send confused students into a spiral of misunderstanding. Our Direct Measurement Video team is working to create several series' of videos with an interface that allows students to interact with them in a way that (we hope) will start to feel lab-like, but with fewer of the impediments that tend to undermine lab-learning in the real world. We hope that lab-like videos will soon provide a needed complement to traditional hands-on labs in science classrooms across the nation. In this talk, I will present our vision of the pedagogical possibilities of video and highlight our progress toward the goal. This work is supported by NSF TUES award #1245268

    Highlights: ► Integration object oriented data access layer in LabVIEW. ► A new component of the MDSplus data acquisition package. ► A new approach in the graphical presentation of data acquisition systems. -- Abstract: The paper presents a new interface providing full integration of MDSplus in LabVIEW, based on the recent features of MDSplus, in particular, data streaming, multithreading and Object Oriented interface. Data streaming support fits into the data driven concept of LabVIEW and multithreading is a native concept in LabVIEW. The object oriented interface of MDSplus defines a set of classes which map specific functionality, such as Tree and TreeNode to represent pulse files and data items, respectively, and fits naturally into the LabVIEW Object Oriented programming interface (LVOOP) introduced in version 8.2. MDSplus objects have been mapped onto LabVIEW objects, which act as wrappers to the underlying MDSplus object instance. This approach allows exporting the full MDSplus functionality into LabVIEW retaining the language-independent system view provided by the MDSplus object oriented interface.

    2015-02-07

    In the last years, the field of probiotics has grown notably. However, out of the thousands of strains isolated each year in the labs around the world, very few enter in a phase of industrial development and even a lower number go to the market. In this article, the main aspects that have to be taken into account in the, usually, long and winding road that a strain must follow from isolation to the market are reviewed Results and conclusions: A probiotic microorganism has to be correctly identified at the species and strain levels. The genome sequence is the gold identification standard and provides valuable information on the safety, functionality and technological properties of a strain. The cases in which a link between a probiotic and an adverse effect has been established are scarce and have involved people with underlying pathologies. There is a wide variety of in vitro, ex vivo and animal model assays for the screening of probiotics, which provide useful information throughout the selection process; however, correctly designed clinical trials are the only way to obtain direct results on the safety and efficacy of a probiotic to the target population. Probiotic companies have the need to obtain a very high bacterial biomass in an economically viable manner while preserving the concentration of live bacteria required for exerting the expected beneficial effect until the end of the probiotic's shelf life. Finally, commercial aspects play a key role in the decision of starting an industrial development and, eventually, to place a probiotic in the market. Copyright AULA MEDICA EDICIONES 2014.

    The legacy communications link analysis software currently used at Wallops Flight Facility involves processes that are different for command destruct, radar, and telemetry. There is a clear advantage to developing an easy-to-use tool that combines all the processes in one application. Link Analysis in the Mission Planning Lab (MPL) uses custom software and algorithms integrated with Analytical Graphics Inc. Satellite Toolkit (AGI STK). The MPL link analysis tool uses pre/post-mission data to conduct a dynamic link analysis between ground assets and the launch vehicle. Just as the legacy methods do, the MPL link analysis tool calculates signal strength and signal- to-noise according to the accepted processes for command destruct, radar, and telemetry assets. Graphs and other custom data are generated rapidly in formats for reports and presentations. STK is used for analysis as well as to depict plume angles and antenna gain patterns in 3D. The MPL has developed two interfaces with the STK software (see figure). The first interface is an HTML utility, which was developed in Visual Basic to enhance analysis for plume modeling and to offer a more user friendly, flexible tool. A graphical user interface (GUI) written in MATLAB (see figure upper right-hand corner) is also used to quickly depict link budget information for multiple ground assets. This new method yields a dramatic decrease in the time it takes to provide launch managers with the required link budgets to make critical pre-mission decisions. The software code used for these two custom utilities is a product of NASA's MPL.

    2015-06-01

    Rochester's second semester physical chemistry lab course is based on spectroscopy experiments and follows a full semester of quantum mechanics lectures. The laboratory course is fully separate from the traditional physical chemistry course and has its own lectures. The lab course is constructed to achieve three major goals: provide a detailed knowledge of the instrumentation that acquires data, establish a good understanding of how that data is analyzed, and give students a familiarity with spectroscopic techniques and quantum mechanical models. Instrumentation is emphasized by using common components to construct different experiments. Microwave, modulation and detection components are used for both OCS pure rotation and ESR experiments. Optical components, a monochromator, and PMT detectors are used in a HeNe laser induced fluorescence experiment on I2 {(J. Chem. Ed. 73, 576 (1996)) and a photoluminescence experiment on pyrene {(J. Chem. Ed. 73, 580 (1996)). OCS is studied in both the microwave and infrared regions, and the C=S stretching vibration is identified through microwave intensity measurements. Lecture notes and laboratory instructions are combined in an exhaustive text of more than 400 pages, containing 325 figures, 285 equations and numerous MathCad data analysis programs. This text can be downloaded as a 10 Mbyte pdf file at chem.rochester.edu/˜muenter/CHEM232Manual.

  14. Enabling miniaturised personalised diagnostics: from lab-on-a-chip to lab-in-a-drop.

    2017-09-26

    The concept of personalised diagnostics is to direct accurate clinical decisions based on an individual's unique disease molecular profile. Lab-on-a-chip (LOC) systems are prime personalised diagnostics examples which seek to perform an entire sample-to-outcome detection of disease nucleic acid (NA) biomarkers on a single miniaturised platform with minimal user handling. Despite the great potential of LOC devices in providing rapid, portable, and inexpensive personalised diagnosis at the point-of-care (POC), the translation of this technology into widespread use has still been hampered by the need for sophisticated and complex engineering. As an alternative miniaturised diagnostics platform free of precision fabrication, there have been recent developments towards a solution-based lab-in-a-drop (LID) system by which an entire laboratory-based diagnostics workflow could be downscaled and integrated within a singular fluid droplet for POC detection of NA biomarkers. In contrast to existing excellent reviews on miniaturised LOC fabrication and individual steps of NA biomarker sensing, we herein focus on miniaturised solution-based NA biosensing strategies suited for integrated LID personalised diagnostics development. In this review, we first evaluate the three fundamental bioassay steps for miniaturised NA biomarker detection: crude sample preparation, isothermal target amplification, and detection readout of amplicons. Then, we provide insights into research advancements towards a functional LID system which integrates all three of the above-mentioned fundamental steps. Finally, we discuss perspectives and future directions of LID diagnostic platforms in personalised medicine applications.

    Our recent study showed that two lab courses, whose goals were exclusively to reinforce material developed in the lecture courses, do not have any impact on exam performance at the 1% level. In this study, we replicated this analysis with a modified version of one of these lab courses whose goals also included modeling, designing experiments, and analyzing and visualizing data. This modified course used the same sets of apparatus as the previous version, but changed the pre-lab and in-lab activities to focus on developing and testing models with data. The study evaluated the impact of these additional goals and activities. We found that they did not affect students' performance on the final exam.

  13. MACMA: a Virtual Lab for Plate Tectonics

    Science.gov (United States)

    Grigne, C.; Combes, M.; Tisseau, C.

    2013-12-01

    MACMA (Multi-Agent Convective MAntle) is a tool developed to simulate evolutive plate tectonics and mantle convection in a 2-D cylindrical geometry (Combes et al., 2012). The model relies mainly on a force balance to compute the velocity of each plate, and on empirical rules to determine how plate boundaries move and evolve. It includes first-order features of plate tectonics: (a) all plates on Earth do not have the same size, (b) subduction zones are asymmetric, (c) plates driven by subducting slabs and upper plates do not exhibit the same velocities, and (d) plate boundaries are mobile, can collide, merge and disappear, and new plate boundaries can be created. The MACMA interface was designed to be user-friendly and a simple use of the simulator can be achieved without any prerequisite knowledge in fluid dynamics, mantle rheology, nor in numerical methods. As a preliminary study, the simulator was used by a few students from bachelor's degree to master's degree levels. An initial configuration for plate tectonics has to be created before starting a simulation: the number and types of plate boundaries (ridge, subduction, passive margins) has to be defined and seafloor ages must be given. A simple but interesting exercise consists in letting students build such an initial configuration: they must analyze a map of tectonic plates, choose a 2-D section and examine carefully a map of seafloor ages. Students mentioned that the exercise made them realize that the 3-D spherical structure of plate tectonics does not translate directly in a simple 2-D section, as opposed to what is usually shown in books. Physical parameters: e.g. mantle viscosity, number of layers to consider in the mantle (upper and lower mantle, possible asthenosphere), initial time and mantle temperature, have to be chosen, and students can use this virtual lab to see how different scenarios emerge when parameters are varied. Very importantly, the direct visualization of the mobility of plate

    2016-01-01

    Our Hybrid Reality and Advanced Operations Lab is developing incredibly realistic and immersive systems that could be used to provide training, support engineering analysis, and augment data collection for various human performance metrics at NASA. To get a better understanding of what Hybrid Reality is, let's go through the two most commonly known types of immersive realities: Virtual Reality, and Augmented Reality. Virtual Reality creates immersive scenes that are completely made up of digital information. This technology has been used to train astronauts at NASA, used during teleoperation of remote assets (arms, rovers, robots, etc.) and other activities. One challenge with Virtual Reality is that if you are using it for real time-applications (like landing an airplane) then the information used to create the virtual scenes can be old (i.e. visualized long after physical objects moved in the scene) and not accurate enough to land the airplane safely. This is where Augmented Reality comes in. Augmented Reality takes real-time environment information (from a camera, or see through window, and places digitally created information into the scene so that it matches with the video/glass information). Augmented Reality enhances real environment information collected with a live sensor or viewport (e.g. camera, window, etc.) with the information-rich visualization provided by Virtual Reality. Hybrid Reality takes Augmented Reality even further, by creating a higher level of immersion where interactivity can take place. Hybrid Reality takes Virtual Reality objects and a trackable, physical representation of those objects, places them in the same coordinate system, and allows people to interact with both objects' representations (virtual and physical) simultaneously. After a short period of adjustment, the individuals begin to interact with all the objects in the scene as if they were real-life objects. The ability to physically touch and interact with digitally created

    1999-09-02

    A new data analysis system has been developed with computer-controlled beam and sample positioning, video sample imaging, multiple large solid angle detectors for X-rays and gamma-rays, and surface barrier detectors for charged particles. The system uses the LabVIEW{sup TM} programming language allowing it to be easily ported between different computer operating systems. In the present configuration, digital signal processors are directly interfaced to a SCSI CAMAC controller. However, the modular software design permits the substitution of other hardware with LabVIEW-supported drivers. On-line displays of histogram and two-dimensional elemental map images provide a user-friendly data acquisition interface. Subregions of the two-dimensional maps may be selected interactively for detailed analysis or for subsequent scanning. Off-line data processing of archived data currently yields elemental maps, analyzed spectra and reconstructions of tomographic data.

    2011-06-01

    In this paper, a novel method is proposed and demonstrated to be able to lyse gram-negative (E. coli) bacteria cells for Lab-on-a-Chip applications. The proposed method incorporates using titanium dioxide particles as photocatalysts and a miniaturized UV LED array as an excitation light source to perform cell lysis on microchips. The experimental result demonstrates the feasibility of the proposed prototype device. The working device suggests an inexpensive, easy to be fabricated and effective way for microchip cell lysis. The miniaturized UV LED array and the microchip with a reaction chamber can be easily integrated with other functional components to form a customized whole Lab-on-a-Chip system.

    Full Text Available Incremental innovation, something better or cheaper or more effective, is the standard innovation process for medical product development. Disruptive innovation is often not recognized as disruptive, because it very often starts as a simple and easy alternative to existing products with much reduced features and bad performance. Innovation is the invention multiplied with a commercial use, or in other words something that eventually provides a value to a clinical user or patient. To create such innovation not a technology push (technology delivered from a technical need perspective but rather a pull (by learning and working with the clinical users is required. Medical technology students need to understand that only through proper observation, procedure know-how and subsequent analysis and evaluation, clinically relevant and affordable innovation can be generated and possibly subsequently used for entrepreneurial ventures. The dedicated laboratory for innovation, research and entrepreneurship- INNOLAB ego.-INKUBATOR IGT (Image Guided Therapies is financed by the state of Sachsen-Anhalt as part of the European ego.-INKUBATOR program with (EFRE funds at the university clinic operated by the technical chair for catheter technologies and image guided surgeries. It forms a network node between medicine, research and economics. It teaches students to lead innovation processes, technology transfer to the user and is designed to stimulate the start-up intentions.

    There is an increasing gap between students of the twenty-first century and the teaching methodology still stuck in the past century. The myriad stimuli that involve our students, immediate consumption of information, and the availability of resources, should cast the teacher in search methodologies that encourage the student to learn. The simulators, virtual laboratories and remote controlled robotic equipment are examples of high didactic potential resources, created by scientific organizations and universities, to be used in education, providing a direct interaction with science and motivating our students to a future career in science. It is up to us to take advantage of that work, and those resources, to light the sparkle in the eyes of our students. In Astronomy Club I've developed with high school students some practical projects in science, using, over the web, the robotic telescopes through which the students are studying and photographing deep sky objects; or the European network of radio telescope, measuring the speed of the arms of our galaxy in our galactic dance, their temperatures showing where it is more likely to form new stars. Students use these tools, engaging in their own knowledge construction, and forego their Friday afternoons without a hurry to go home for the weekend. That's the spirit we want for the school.

  19. Habermas on European Constitution and European Identity

    Directory of Open Access Journals (Sweden)

    Éva Biró-Kaszás

    2010-12-01

    Full Text Available For the last two decades or so philosophers have been reflecting on a set of practical and political concerns in connection with the new political structural arrangements beyond the nation-state. In this article two essays by Jürgen Habermas shall be examined. An attempt shall be made to tackle Habermas’ philosophical concepts of personal and collective identity as well as the role that a constitution may play in building the post-national constellation. It has been shown that Habermas has normative answers. Firstly, according to him, the fragile balance between the legal order and the particular cultures and traditions of a community has to be protected by the constitutional state. For that reason the political culture has to be “decoupled” from the majority culture. Secondly, the democratically structured attempt to achieve shared meaning has to find the delicate balance between the context-transcending universal normative claims and the claims of particular individual and collective life. Thirdly, it is possible to expand legally mediated civil solidarity trans-nationally, across Europe – we may recognize this development as the emergence of European identity –, since the process of democratic will-formation of citizens may get loose from the structures provided by the state if both shared democratic political cultures as well as a European-wide public sphere exist. The European Constitution may have a catalytic function in materialization of these conditions. It has been shown that in his deliberations Habermas tried to find a reflective equilibrium between the normative and the empirical.

  20. Engineering students' experiences from physics group work in learning labs

    Science.gov (United States)

    Strøm Mellingsæter, Magnus

    2014-01-01

    Background: This paper presents a case study from a physics course at a Norwegian university college, investigating key aspects of a group-work project, so-called learning labs, from the participating students' perspective. Purpose: In order to develop these learning labs further, the students' perspective is important. Which aspects are essential for how the students experience the learning labs, and how do these aspects relate to the emergence of occurrences termed joint workspace, i.e. the maintenance of content-related dialogues within the group? Programme description: First year mechanical engineering students attended the learning labs as a compulsory part of the physics course. The student groups were instructed to solve physics problems using the interactive whiteboard and then submit their work as whiteboard files. Sample: One group of five male students was followed during their work in these learning labs through one term. Design and methods: Data were collected as video recordings and fieldwork observation. In this paper, a focus group interview with the students was the main source of analysis. The interpretations of the interview data were compared with the video material and the fieldwork observations. Results: The results show that the students' overall experience with the learning labs was positive. They did, however, point to internal aspects of conflicting common and personal goals, which led to a group-work dynamics that seemed to inhibit elaborate discussions and collaboration. The students also pointed to external aspects, such as a close temporal proximity between lectures and exercises, which also seemed to inhibit occurrences termed joint workspace. Conclusions: In order to increase the likelihood of a joint workspace throughout the term in the learning labs, careful considerations have to be made with regard to timing between lectures and exercises, but also with regard to raising the students' awareness about shared and personal goals.

  4. Lab-on-a-chip pathogen sensors for food safety.

    Science.gov (United States)

    Yoon, Jeong-Yeol; Kim, Bumsang

    2012-01-01

    There have been a number of cases of foodborne illness among humans that are caused by pathogens such as Escherichia coli O157:H7, Salmonella typhimurium, etc. The current practices to detect such pathogenic agents are cell culturing, immunoassays, or polymerase chain reactions (PCRs). These methods are essentially laboratory-based methods that are not at all real-time and thus unavailable for early-monitoring of such pathogens. They are also very difficult to implement in the field. Lab-on-a-chip biosensors, however, have a strong potential to be used in the field since they can be miniaturized and automated; they are also potentially fast and very sensitive. These lab-on-a-chip biosensors can detect pathogens in farms, packaging/processing facilities, delivery/distribution systems, and at the consumer level. There are still several issues to be resolved before applying these lab-on-a-chip sensors to field applications, including the pre-treatment of a sample, proper storage of reagents, full integration into a battery-powered system, and demonstration of very high sensitivity, which are addressed in this review article. Several different types of lab-on-a-chip biosensors, including immunoassay- and PCR-based, have been developed and tested for detecting foodborne pathogens. Their assay performance, including detection limit and assay time, are also summarized. Finally, the use of optical fibers or optical waveguide is discussed as a means to improve the portability and sensitivity of lab-on-a-chip pathogen sensors.

    The European Universe Awareness (EU-UNAWE) programme uses the beauty and grandeur of the cosmos to encourage young children, particularly those from underprivileged backgrounds, to develop an interest in science and technology and to foster a sense of global citizenship. EU-UNAWE is already active in 40 countries and comprises a global network of almost 500 astronomers, teachers and other educators. The programme was recently awarded a grant of 1.9 million euros by the European Union so that it can be further developed in five European countries and South Africa. The grant will be used to organise teacher training workshops and to develop educational materials, such as an astronomy news service for children and games. During this presentation we will outline some of the biggest achievements of EU-UNAWE to date and discuss future plans for the programme.

  11. The European Identity

    2017-09-01

    Full Text Available European identity is not only a scientifically interesting question, but also a politically important issue: in fact, sixty years after the signing of the Treaty of Rome, the European Union finds itself for the first time facing risks that threaten its own existence. The European Union is a limited and incomplete project because Europe’s economic integration has not been accompanied by a genuine supranational political union and greater cultural integration. The deficit of democratic representation and cultural integration is due to the fact that the community process is based only on economic rationality and not on a feeling of common belonging. In the current situation in which the Union faces difficult challenges which threaten to undermine the future, it necessary to affirm the policy of interests with a policy of identity. In this essay, we will first concentrate on the concept of identity – that is on the nucleus of values and common institutions –; then we will discuss how the European identity has changed over time (also in relation to national identities and what are the mechanisms that may favour its taking root in the current situation. The European project of political unification needs to be re-emphasized, finding the way to a European collective identity, not contrasted with but alongside the different national identities, referring to loyalty and shared commitment to a whole collection of cultural values: fundamental human rights, civil liberties, democratic political institutions, rule of law, freedom of movement of people, goods and capital, social justice and non-violent resolution of conflicts.

  12. Magnetic Particle Recovery of Serial Numbers

    2003-10-01

    One method used by crime labs to recover obliterated serial numbers in steel firearms (ferrous samples) is the magnetic particle technique. The use of this method is predicated on the detection of metal deformation present under stamped serial numbers after the visible stamp has been removed. Equipment specialized for this detection is not used in these attempts; a portable magnetic yoke used typically for flaw detection on large weldments or structures, along with dry visible magnetic powders, have been the tools of criminologists working in this area. Crime labs have reported low success rates using these tools [1, 2]. This is not surprising when one considers that little formal development has apparently evolved for use in such investigations since the publication of seminal work in this area some time ago [3]. The aim of this project is to investigate specific aspects of magnetic particle inspection for serial number recovery. This includes attempts to understand the magnetic characteristics of different steels that affect their performance in the test, such as varying results for carbon steels and alloy steels after different thermal and forming treatments. Also investigated are the effects of the nature of the sample magnetization (AC, rectified DC, and true DC) and the use of various detection media, such as visible powders and fluorescent sprays, on test outcome. Additionally, some aspects of surface preparation of firearm samples prior to number recovery were included in this work. The scope of this report includes a brief overview of the magnetic particle inspection method in general and its applications to forensic serial number recovery. This is followed by a description of how such investigations were simulated on lab samples, including a look at how the microstructure of a given steel will affect its performance in the test.

    Important information on the LambdaN interaction can be obtained from High Resolution Hypenuclear Spectroscopy experiments with electromagnetic probes. A challenging experiment on electroproduction of hypernuclei is scheduled for 2003 in Hall A at Jefferson Lab. One of the challenges is the high performance particle identification system needed. The signal is expected to be rare compared to the very high pion and proton backgrounds due to the small electron and kaon detection angles. The "standard" Hall A PID apparatus (TOF and two aerogel threshold Cherenkov detectors) does not provide sufficient suppression of the background. Simulations and calculations have shown that a RICH detector would solve the problem. A proximity focusing fluorocarbon/CsI detector similar to the ALICE RICH detector has been designed, built, tested and commissioned. The results show that the detector performs as expected.

    DOE funding was used to renovate 4,500 square feet of aging laboratories and classrooms that support science, engineering, and mathematics disciplines (specifically environmental science, and computer engineering). The expansion of the labs was needed to support robotics and environmental science research, and to better accommodate a wide variety of teaching situations. The renovated space includes a robotics laboratory, two multi-use labs, safe spaces for the storage of instrumentation, modern ventilation equipment, and other “smart” learning venues. The renovated areas feature technologies that are environmentally friendly with reduced energy costs. A campus showcase, the laboratories are a reflection of the University’s commitment to the environment and research as a tool for teaching. As anticipated, the labs facilitate the exploration of emerging technologies that are compatible with local and regional economic plans.

    The combination of microfabrication-based technologies with cell biology has laid the foundation for the development of advanced in vitro diagnostic systems capable of analyzing cell cultures under physiologically relevant conditions. In the present review, we address recent lab-on-a-chip developments for stem cell analysis. We highlight in particular the tangible advantages of microfluidic devices to overcome most of the challenges associated with stem cell identification, expansion and differentiation, with the greatest advantage being that lab-on-a-chip technology allows for the precise regulation of culturing conditions, while simultaneously monitoring relevant parameters using embedded sensory systems. State-of-the-art lab-on-a-chip platforms for in vitro assessment of stem cell cultures are presented and their potential future applications discussed. Copyright © 2014 Elsevier Ltd.

  4. Advanced Physics Labs and Undergraduate Research: Helping Them Work Together

    Science.gov (United States)

    Peterson, Richard W.

    2009-10-01

    The 2009 Advanced Lab Topical Conference in Ann Arbor affirmed the importance of advanced labs that teach crucial skills and methodologies by carefully conducting a time-honored experiment. Others however argued that such a constrained experiment can play a complementary role to more open-ended, project experiences. A genuine ``experiment'' where neither student or faculty member is exactly sure of the best approach or anticipated result can often trigger real excitement, creativity, and career direction for students while reinforcing the advanced lab and undergraduate research interface. Several examples are cited in areas of AMO physics, optics, fluids, and acoustics. Colleges and universities that have dual-degree engineering, engineering physics, or applied physics programs may especially profit from interdisciplinary projects that utilize optical, electromagnetic, and acoustical measurements in conjunction with computational physics and simulation.

  5. Promoting Metacognition in Introductory Calculus-based Physics Labs

    Grennell, Drew; Boudreaux, Andrew

    2010-10-01

    In the Western Washington University physics department, a project is underway to develop research-based laboratory curriculum for the introductory calculus-based course. Instructional goals not only include supporting students' conceptual understanding and reasoning ability, but also providing students with opportunities to engage in metacognition. For the latter, our approach has been to scaffold reflective thinking with guided questions. Specific instructional strategies include analysis of alternate reasoning presented in fictitious dialogues and comparison of students' initial ideas with their lab group's final, consensus understanding. Assessment of student metacognition includes pre- and post- course data from selected questions on the CLASS survey, analysis of written lab worksheets, and student opinion surveys. CLASS results are similar to a traditional physics course and analysis of lab sheets show that students struggle to engage in a metacognitive process. Future directions include video studies, as well as use of additional written assessments adapted from educational psychology.

  6. Quantitative comparisons to promote inquiry in the introductory physics lab

    2015-01-01

    In a recent report, the American Association of Physics Teachers has developed an updated set of recommendations for curriculum of undergraduate physics labs.1 This document focuses on six major themes: constructing knowledge, modeling, designing experiments, developing technical and practical laboratory skills, analyzing and visualizing data, and communicating physics. These themes all tie together as a set of practical skills in scientific measurement, analysis, and experimentation. In addition to teaching students how to use these skills, it is important for students to know when to use them so that they can use them autonomously. This requires, especially in the case of analytical skills, high-levels of inquiry behaviours to reflect on data and iterate measurements, which students rarely do in lab experiments. In this paper, we describe a simple framework for structuring the critical thinking and inquiry behaviours relevant to lab work, which focuses on iterative cycles of comparisons between data sets.

The experimental setup currently in operation has been used to check the potential of the TurLab facility for the above purposes, and the acquired data will be used to test the concept of JEM-EUSO's trigger system.

  8. Particle Filtering With Invertible Particle Flow

    Science.gov (United States)

    Li, Yunpeng; Coates, Mark

    2017-08-01

    A key challenge when designing particle filters in high-dimensional state spaces is the construction of a proposal distribution that is close to the posterior distribution. Recent advances in particle flow filters provide a promising avenue to avoid weight degeneracy; particles drawn from the prior distribution are migrated in the state-space to the posterior distribution by solving partial differential equations. Numerous particle flow filters have been proposed based on different assumptions concerning the flow dynamics. Approximations are needed in the implementation of all of these filters; as a result the articles do not exactly match a sample drawn from the desired posterior distribution. Past efforts to correct the discrepancies involve expensive calculations of importance weights. In this paper, we present new filters which incorporate deterministic particle flows into an encompassing particle filter framework. The valuable theoretical guarantees concerning particle filter performance still apply, but we can exploit the attractive performance of the particle flow methods. The filters we describe involve a computationally efficient weight update step, arising because the embedded particle flows we design possess an invertible mapping property. We evaluate the proposed particle flow particle filters' performance through numerical simulations of a challenging multi-target multi-sensor tracking scenario and complex high-dimensional filtering examples.

    This report details the accomplishments and research results for the High Energy Physics Group at the University of Texas at Arlington at the Energy and Intensity Frontiers. For the Energy Frontier we have made fundamental contributions in the search for supersymmetric particles, proposed to explain the stabilization of the mass of the Higgs Boson – the agent giving mass to all known particles. We have also made major contributions to the search for additional Higgs Bosons and to the planning for future searches. This work has been carried out in the context of the ATLAS Experiment at CERN (European Nuclear Research Laboratory) and for which we have made major contributions to computing and data distribution and processing, and have worked to calibrate the detector and prepare upgraded electronics for the future. Our other contribution to the Energy Frontier has been to the International Linear Collider (ILC) project, potentially hosted by Japan, and to the Silicon Detector Concept (SiD) in particular. We have lead the development of the SiD Concept and have worked on a new form of precise energy measurement for particles from the high energy collisions of electrons and positrons at the ILC. For the Intensity Frontier, we have worked to develop the concept of Long Baseline Neutrino Experiment(s) (LBNE) at the Fermi National Accelerator Laboratory. Our contributions to detector development, neutrino beam studies, particle identification, software development will facilitate future studies of the oscillation of one type of neutrino into other type(s), establish the order of the neutrino masses, and, through an innovative new idea, allow us to create a beam of dark matter particles.

  18. European Integration and Globalization

    Directory of Open Access Journals (Sweden)

    Diana Bobica

    2010-06-01

    Full Text Available According to many, the term globalization is able to explain any phenomenon whatsoever, be it positive or negative, that takes place within the global social system. It seems like a sort of magical formula, which is to be found in the speeches of all sorts of people, be they economists, politicians, businessmen or sociologists. However this magical formula of globalization has its limitations, since it encompasses a certain amount of quibbling, beyond which not many can pass. In the context of globalization there appears the question on its role in the process of European integration. Is European integration a part of this global process or, quite on the contrary, does it present certain distinctive features, as it moulds itself differently from the globalization phenomenon? A clear-cut answer seems difficult because of the various aspects involved. Not only the general phenomenon of globalization, but also the economic integration on European level is based on the liberalization of markets and on the opening of national economies towards the exterior,having as direct consequence the intensification of trade exchanges. If from a global point of view one may talk of a market fundamentalism in that the market principles know no boundary, European integration on the other hand implies not only market economy, but also a guided and monitored action of Member Statesaccording to the needs of the whole entity, also taking into consideration - as far as possible – all aspects and consequences on social level.

    Earth science is one of the most important tools that the global community needs to address the pressing environmental, social, and economic issues of our time. While, at times considered a second-rate science at the high school level, it is currently undergoing a major revolution in the depth of content and pedagogical vitality. As part of this revolution, labs in Earth science courses need to shift their focus from cookbook-like activities with known outcomes to open-ended investigations that challenge students to think, explore and apply their learning. We need to establish a new model for Earth science as a rigorous lab science in policy, perception, and reality. As a concerted response to this need, five states, a coalition of scientists and educators, and an experienced curriculum team are creating a national model for a lab-based high school Earth science course named EarthLabs. This lab course will comply with the National Science Education Standards as well as the states' curriculum frameworks. The content will focus on Earth system science and environmental literacy. The lab experiences will feature a combination of field work, classroom experiments, and computer access to data and visualizations, and demonstrate the rigor and depth of a true lab course. The effort is being funded by NOAA's Environmental Literacy program. One of the prototype units of the course is Investigating Hurricanes. Hurricanes are phenomena which have tremendous impact on humanity and the resources we use. They are also the result of complex interacting Earth systems, making them perfect objects for rigorous investigation of many concepts commonly covered in Earth science courses, such as meteorology, climate, and global wind circulation. Students are able to use the same data sets, analysis tools, and research techniques that scientists employ in their research, yielding truly authentic learning opportunities. This month-long integrated unit uses hurricanes as the story line by

    The European Network for Light Ion Hadron Therapy (ENLIGHT) was established in 2002 to coordinate European efforts on hadron therapy (radiotherapy performed with protons and light ions instead of high-energy photons). The ENLIGHT network is formed by the European Hadron Therapy Community, with more than 300 participants from 20 different countries. A major success of ENLIGHT has been uniting traditionally separate communities so that clinicians, physicists, biologists, and engineers with experience and interest in particle therapy work together. ENLIGHT has been a successful initiative in forming a common European platform and bringing together people from diverse disciplines. ENLIGHT demonstrates the advantages of regular and organized exchanges of data, information, and best practices, as well as determining and following strategies for future needs in research and technological development in the hadron therapy field.

    Guided learning labs as alternatives to traditional style chemistry-related labs were tested in the course, Topics in Physical Science. Guided learning labs emphasized students' conceptual understanding of the science content and actively involved the instructor during the lab. The control group performed traditional lab exorcise while students who carried out the guided learning activities formed the treatment group. Both groups had similar demographic and academic backgrounds. This research compared student performances on the three labs: Density, Kinetic Theory and Chemical Reactions. Both groups completed pre-lab and post-lab quizzes and answered conceptual questions for each lab. Students also participated in a post-course quiz via email. Scores on all these assessments were compared using independent samples t tests. The treatment group outscored the control group on all summary assessments, and performed significantly better than the control group on the post-lab quizzes and conceptual questions for all three labs. Students in the treatment group demonstrated stronger Pearson's correlations between their ACT Mathematics, Science Reasoning and Reading Comprehension scores and their scores on the assessments. Student reactions to the guided learning style of lab were favorable. The implication is that guided learning labs improve conceptual understanding of chemistry concepts in a physical science lab course.

    Full Text Available Soviet scientific school of pan-European integration studies began to emerge in the 1960s at the Institute of World Economy and International Relations (Russian Academy of Science. Among the leading scientists who have developed methodological approaches of Soviet integration studies were M.M. Maximova, Y.A. Borko, Y. Shishkov, L.I. Capercaillie. Later, a new center for integration studies became the Institute of Europe, created in 1987. It was led by such renowned scientists as Academicians V.V. Zhurkin and N.P. Shmelev. In the 1980s the subject of the integration process in Europe attracted attention of experts from MGIMO. An important role in the development of school of integration research in the USSR was played by a MGIMO professor, head of the chair of history of international relations and foreign policy of the USSR V.B. Knyazhinskiy. His work contributed to the deliverance of the national scientific community from skepticism about the prospects for European integration. Ideas of V.B. Knyazhinsky are developed today in MGIMO by his followers A.V. Mal'gin and T.V. Ur'eva. In the mid-1990s, having retired from diplomatic service, professor Yu. Matveevskiy started to work at MGIMO. With a considerable practical experience in the field, he produced a series of monographs on the history of European integration. In his works, he analyses the development of integration processes in Western Europe from their inception to the present day, showing the gradual maturation of the necessary spiritual and material prerequisites for the start of integration and traces the various stages of the "integration". In the late 1990s, the growing demand from the domestic business and government for professionals who are capable of interacting with the European Union, has produced the necessary supply in the form of educational programs based on accumulated scientific knowledge. Setting up a discipline "European Integration" was a major step in the development

    Contamination of foods is a public health hazard that episodically causes thousands of deaths and sickens millions worldwide. To ensure food safety and quality, rapid, low-cost and easy-to-use detection methods are desirable. Here, the LabSystem is introduced for integrated, automated DNA purification, amplification and detection. It consists of a disposable, centrifugally driven DNA purification platform (LabTube) and a low-cost UV/vis-reader (LabReader). For demonstration of the LabSystem in the context of food safety, purification of Escherichia coli (non-pathogenic E. coli and pathogenic verotoxin-producing E. coli (VTEC)) in water and milk and the product-spoiler Alicyclobacillus acidoterrestris (A. acidoterrestris) in apple juice was integrated and optimized in the LabTube. Inside the LabReader, the purified DNA was amplified, readout and analyzed using both qualitative isothermal loop-mediated DNA amplification (LAMP) and quantitative real-time PCR. For the LAMP-LabSystem, the combined detection limits for purification and amplification of externally lysed VTEC and A. acidoterrestris are 10(2)-10(3) cell-equivalents. In the PCR-LabSystem for E. coli cells, the quantification limit is 10(2) cell-equivalents including LabTube-integrated lysis. The demonstrated LabSystem only requires a laboratory centrifuge (to operate the disposable, fully closed LabTube) and a low-cost LabReader for DNA amplification, readout and analysis. Compared with commercial DNA amplification devices, the LabReader improves sensitivity and specificity by the simultaneous readout of four wavelengths and the continuous readout during temperature cycling. The use of a detachable eluate tube as an interface affords semi-automation of the LabSystem, which does not require specialized training. It reduces the hands-on time from about 50 to 3 min with only two handling steps: sample input and transfer of the detachable detection tube.

    As part of the Stage Analysis Branch, human factors engineering plays an important role in relating humans to the systems of hardware and structure designs of the new launch vehicle. While many branches are involved in the technical aspects of creating a launch vehicle, human factors connects humans to the scientific systems with the goal of improving operational performance and safety while reducing operational error and damage to the hardware. Human factors engineers use physical and computerized models to visualize possible areas for improvements to ensure human accessibility to components requiring maintenance and that the necessary maintenance activities can be accomplished with minimal risks to human and hardware. Many methods of testing are used to fulfill this goal, such as physical mockups, computerized visualization, and usability testing. In this analysis, a usability test is conducted to test how usable a website is to users who are and are not familiar with it. The testing is performed using participants and Morae software to record and analyze the results. This analysis will be a preliminary test of the usability lab in preparation for use in new spacecraft programs, NASA Enterprise, or other NASA websites. The usability lab project is divided into two parts: integration of the usability lab and a preliminary test of the usability lab.

  19. Quantitative Comparisons to Promote Inquiry in the Introductory Physics Lab

    In a recent report, the American Association of Physics Teachers has developed an updated set of recommendations for curriculum of undergraduate physics labs. This document focuses on six major themes: constructing knowledge, modeling, designing experiments, developing technical and practical laboratory skills, analyzing and visualizing data, and communicating physics. These themes all tie together as a set of practical skills in scientific measurement, analysis, and experimentation. In addition to teaching students how to use these skills, it is important for students to know when to use them so that they can use them autonomously. This requires, especially in the case of analytical skills, high levels of inquiry behaviors to reflect on data and iterate measurements, which students rarely do in lab experiments. Often, they perform lab experiments in a plug-and-chug frame, procedurally completing each activity with little to no sensemaking. An emphasis on obtaining true theoretical values or agreement on individual measurements also reinforces inauthentic behaviors such as retroactively inflating measurement uncertainties. This paper aims to offer a relatively simple pedagogical framework for engaging students authentically in experimentation and inquiry in physics labs.
