    2014-01-01

    We report on the design, operation, and data analysis methods employed on the VNIR imaging spectrometer instrument that was part of the Mars Astrobiology Research and Technology Experiment (MARTE). The imaging spectrometer is a hyperspectral scanning pushbroom device sensitive to VNIR wavelengths from 400-1000 nm. During the MARTE project, the spectrometer was deployed to the Rio Tinto region of Spain. We analyzed subsets of 3 cores from Rio Tinto using a new band modeling technique. We found most of the MARTE drill cores to contain predominantly goethite, though spatially coherent areas of hematite were identified in Core 23. We also distinguished non Fe-bearing minerals that were subsequently analyzed by X-ray diffraction (XRD) and found to be primarily muscovite. We present drill core maps that include spectra of goethite, hematite, and non Fe-bearing minerals.

    The 2005 Mars Astrobiology Research and Technology Experiment (MARTE) project conducted a simulated 1-month Mars drilling mission in the Río Tinto district, Spain. Dry robotic drilling, core sampling, and biological and geological analytical technologies were collectively tested for the first time for potential use on Mars. Drilling and subsurface sampling and analytical technologies are being explored for Mars because the subsurface is the most likely place to find life on Mars. The objectives of this work are to describe drilling, sampling, and analytical procedures; present the geological analysis of core and borehole material; and examine lessons learned from the drilling simulation. Drilling occurred at an undisclosed location, causing the science team to rely only on mission data for geological and biological interpretations. Core and borehole imaging was used for micromorphological analysis of rock, targeting rock for biological analysis, and making decisions regarding the next day's drilling operations. Drilling reached 606 cm depth into poorly consolidated gossan that allowed only 35% of core recovery and contributed to borehole wall failure during drilling. Core material containing any indication of biology was sampled and analyzed in more detail for its confirmation. Despite the poorly consolidated nature of the subsurface gossan, dry drilling was able to retrieve useful core material for geological and biological analysis. Lessons learned from this drilling simulation can guide the development of dry drilling and subsurface geological and biological analytical technologies for future Mars drilling missions.

    Sampling of subsurface rock may be required to detect evidence of past biological activity on Mars. The Mars Astrobiology Research and Technology Experiment (MARTE) utilized the Río Tinto region, Spain, as a Mars analog site to test dry drilling technologies specific to Mars that retrieve subsurface rock for biological analysis. This work examines the usefulness of visible-near infrared (VNIR) (450-1000 nm) point spectrometry to characterize ferric iron minerals in core material retrieved during a simulated Mars drilling mission. VNIR spectrometry can indicate the presence of aqueously precipitated ferric iron minerals and, thus, determine whether biological analysis of retrieved rock is warranted. Core spectra obtained during the mission with T1 (893-897 nm) and T2 (644-652 nm) features indicate goethite-dominated samples, while relatively lower wavelength T1 (832-880 nm) features indicate hematite. Hematite/goethite molar ratios varied from 0 to 1.4, and within the 880-898 nm range, T1 features were used to estimate hematite/goethite molar ratios. Post-mission X-ray analysis detected phyllosilicates, which indicates that examining beyond the VNIR (e.g., shortwave infrared, 1000-2500 nm) will enhance the detection of other minerals formed by aqueous processes. Despite the limited spectral range of VNIR point spectrometry utilized in the MARTE Mars drilling simulation project, ferric iron minerals could be identified in retrieved core material, and their distribution served to direct core subsampling for biological analysis.

    Use of unmanned systems is rapidly growing within the military and civilian sectors in a variety of roles including reconnaissance, surveillance, explosive ordinance disposal (EOD), and force-protection and perimeter security. As utilization of these systems grows at an ever increasing rate, the need for unmanned systems teaming and inter-system collaboration becomes apparent. Collaboration provides a means of enhancing individual system capabilities through relevant data exchange that contributes to cooperative behaviors between systems and enables new capabilities not possible if the systems operate independently. A collaborative networked approach to development holds the promise of adding mission capability while simultaneously reducing the workload of system operators. The Joint Collaborative Technology Experiment (JCTE) joins individual technology development efforts within the Air Force, Navy, and Army to demonstrate the potential benefits of interoperable multiple system collaboration in a force-protection application. JCTE participants are the Air Force Research Laboratory, Materials and Manufacturing Directorate, Airbase Technologies Division, Force Protection Branch (AFRL/RXQF); the Army Aviation and Missile Research, Development, and Engineering Center Software Engineering Directorate (AMRDEC SED); and the Space and Naval Warfare Systems Center - Pacific (SSC Pacific) Unmanned Systems Branch operating with funding provided by the Joint Ground Robotics Enterprise (JGRE). This paper will describe the efforts to date in system development by the three partner organizations, development of collaborative behaviors and experimentation in the force-protection application, results and lessons learned at a technical demonstration, simulation results, and a path forward for future work.

    1976-12-08

    A one-year technology-transfer project involving ERDA installations and Hawaii consisted of sending teams from the Lawrence Livermore Laboratory on week-long field trips every two months to test the effectiveness of different methods of transferring technology information from federal sources to civilian clients. The team was questioned primarily on non-energy matters, and the energy questions asked related mostly to individuals or small industries. The team responed to all questions and found that a wide range of knowledge was more effective than having a sequence of experts. Hawaiians considered current major ERDA projects to be irrelevant to their needs. The team was most successful on a one-to-one basis because large groups and state agencies tend to be more policy- than action-oriented. Personal followup was considered essential. The team also learned that their visits generated ten times as many inquiries as were received unsolicited by the laboratory. Most inquiries involved biomass and use of agricultural wastes, solar energy, and transportation. An important contribution of the team's workshops was linking groups to work together on common problems. An appendix lists the subjects of queries and the names and addresses of consortium participants and Hawaiian contacts. (DCK)

    The MIT Space Engineering Research Center and the Jet Propulsion Laboratory stand ready to advance science sensor technology for discrete-aperture astronomical instruments such as space-based optical interferometers. The objective of the Stellar Interferometer Technology Experiment (SITE) is to demonstrate system-level functionality of a space-based stellar interferometer through the use of enabling and enhancing Controlled-Structures Technologies (CST). SITE mounts to the Mission Peculiar Experiment Support System inside the Shuttle payload bay. Starlight, entering through two apertures, is steered to a combining plate where it is interferred. Interference requires 27 nanometer pathlength (phasing) and 0.29 archsecond wavefront-tilt (pointing) control. The resulting 15 milli-archsecond angular resolution exceeds that of current earth-orbiting telescopes while maintaining low cost by exploiting active optics and structural control technologies. With these technologies, unforeseen and time-varying disturbances can be rejected while relaxing reliance on ground alignment and calibration. SITE will reduce the risk and cost of advanced optical space systems by validating critical technologies in their operational environment. Moreover, these technologies are directly applicable to commercially driven applications such as precision matching, optical scanning, and vibration and noise control systems for the aerospace, medical, and automotive sectors. The SITE team consists of experienced university, government, and industry researchers, scientists, and engineers with extensive expertise in optical interferometry, nano-precision opto-mechanical control and spaceflight experimentation. The experience exists and the technology is mature. SITE will validate these technologies on a functioning interferometer science sensor in order to confirm definitely their readiness to be baselined for future science missions.

    The Advanced Communication Technology Satellite (ACTS) is a key to reaching NASA's goal of developing high-risk, advanced communications technology using multiple frequency bands to support the nation's future communication needs. Using the multiple, dynamic hopping spot beams, and advanced on board switching and processing systems, ACTS will open a new era in communications satellite technology. One of the key technologies to be validated as part of the ACTS program is the multibeam antenna with rapidly reconfigurable hopping and fixed spot beam to serve users equipped with small-aperature terminals within the coverage areas. The proposed antenna technology experiments are designed to evaluate in-orbit ACTS multibeam antenna performance (radiation pattern, gain, cross pol levels, etc.).

  8. Technologies of democracy: experiments and demonstrations.

    Laurent, Brice

    2011-12-01

    Technologies of democracy are instruments based on material apparatus, social practices and expert knowledge that organize the participation of various publics in the definition and treatment of public problems. Using three examples related to the engagement of publics in nanotechnology in France (a citizen conference, a series of public meetings, and an industrial design process), the paper argues that Science and Technology Studies provide useful tools and methods for the analysis of technologies of democracy. Operations of experiments and public demonstrations can be described, as well as controversies about technologies of democracy giving rise to counter-experiments and counter-demonstrations. The political value of the analysis of public engagement lies in the description of processes of stabilization of democratic orders and in the display of potential alternative political arrangements.

    This paper examines the approach taken to building a low-cost, modular spacecraft bus that can be used to support a variety of technology experiments in different space environments. It describes the techniques used and design drivers considered to ensure experiment independence from as yet selected host spacecraft. It describes the technology experiment carriers that will support NASA's Living With a Star Space Environment Testbed space missions. NASA has initiated the Living With a Star (LWS) Program to develop a better scientific understanding to address the aspects of the connected Sun-Earth system that affect life and society. A principal goal of the program is to bridge the gap between science, engineering, and user application communities. The Space Environment Testbed (SET) Project is one element of LWS. The Project will enable future science, operational, and commercial objectives in space and atmospheric environments by improving engineering approaches to the accommodation and/or mitigation of the effects of solar variability on technological systems. The SET Project is highly budget constrained and must seek to take advantage of as yet undetermined partnering opportunities for access to space. SET will conduct technology validation experiments hosted on available flight opportunities. The SET Testbeds will be developed in a manner that minimizes the requirements for accommodation, and will be flown as flight opportunities become available. To access the widest range of flight opportunities, two key development requirements are to maintain flexibility with respect to accommodation constraints and to have the capability to respond quickly to flight opportunities. Experiments, already developed to the technology readiness level of needing flight validation in the variable Sun-Earth environment, will be selected on the basis of the need for the subject technology, readiness for flight, need for flight resources and particular orbit. Experiments will be

    The Lithium-ion battery has been perceived ten years ago by EADS Astrium as a very promising technology in terms of technical, industrial and cost aspects for satellite platforms with respect to NiCd and NiH2 technologies. In 2008, lithium technology is the baseline for all new spacecrafts, whatever the missions.For telecommunication satellite, since 2003, more than 18 Lithium batteries for Eurostar E3000 platform have been fully tested and integrated (with SAFT VES140S Lithium cells) up to now. 6 E3000 satellites are in orbit equipped with Lithium batteries with more than 4 years in orbit for the first E3000 satellite equipped with Lithium-ion batteries. 7 others E3000 satellites with lithium batteries are currently at various stage of production.For LEO missions (THEOS, PLEIADES…), ABSL batteries with Sony 18650 HC lithium cells will replace, on the latest LEO platform the NiCd technology. The same technology change has been also successfully done previously for scientific missions: since June 2003 for Mars Express and November 2005 for Venus Express.Associated expected system improvements (weight reduction of the battery system, easiest on ground and launch pad management, highest available energy during launch, ….) driven by specific lithium-ion technology features are today demonstrated and in orbit behaviours are as expected [1], [13].The paper will give an overview of experience of EADS-Astrium on lithium battery technology with the description (design, management, architecture) of lithium batteries used on board LEO and GEO satellites. It will give also a picture of the effort done the last ten years to reach this level of experience (test characterisation, simulation…).

    Full Text Available La misión astrobiológica más importante que se ha realizado hasta la fecha ha sido sin duda el proyecto Vikingo de la NASA. Esta misión consistió en tres experimentos biológicos especialmente diseñados para la búsqueda de indicadores de vida en las capas superficiales del suelo marciano. Los tres experimentos dieron resultados positivos. Sin embargo, el análisis de materia orgánica en el suelo marciano demostró la ausencia total de carbono orgánico. Este hallazgo fue utilizado como uno de los argumentos más sólidos en contra de la existencia de vida en la superficie del planeta Marte. Como preparación para futuras misiones a Marte en búsqueda de vida es necesario probar los instrumentos en localidades terrestres que pudieran ser ambientes análogos a Marte. Uno de los desiertos más áridos del planeta es el de Atacama, en el norte de Chile. Estudios químicos y microbiológicos del suelo de Atacama sugieren que el corazón del desierto es en realidad un buen análogo de Marte, ya que no posee vida macroscópica y microscópica, tiene niveles muy bajos de materia orgánica, y sus suelos son muy reactivos. En colaboración con científicos franceses y estadounidenses, estamos preparando una misión robótica dirigida por la NASA para la búsqueda de vida pasada o presente en Marte por lo que el Desierto de Atacama en Chile es el escenario para la preparación de esta misión espacial.

    2014-01-23

    During the 2009 influenza A(H1N1) pandemic, a new laboratory-based virological sentinel surveillance system, the Respiratory DataMart System (RDMS), was established in a network of 14 Health Protection Agency (now Public Health England (PHE)) and National Health Service (NHS) laboratories in England. Laboratory results (both positive and negative) were systematically collected from all routinely tested clinical respiratory samples for a range of respiratory viruses including influenza, respiratory syncytial virus (RSV), rhinovirus, parainfluenza virus, adenovirus and human metapneumovirus (hMPV). The RDMS also monitored the occurrence of antiviral resistance of influenza viruses. Data from the RDMS for the 2009–2012 period showed that the 2009 pandemic influenza virus caused three waves of activity with different intensities during the pandemic and post pandemic periods. Peaks in influenza A(H1N1)pdm09 positivity (defined as number of positive samples per total number of samples tested) were seen in summer and autumn in 2009, with slightly higher peak positivity observed in the first post-pandemic season in 2010/2011. The influenza A(H1N1)pdm09 virus strain almost completely disappeared in the second postpandemic season in 2011/2012. The RDMS findings are consistent with other existing community-based virological and clinical surveillance systems. With a large sample size, this new system provides a robust supplementary mechanism, through the collection of routinely available laboratory data at minimum extra cost, to monitor influenza as well as other respiratory virus activity. A near real-time, daily reporting mechanism in the RDMS was established during the London 2012 Olympic and Paralympic Games. Furthermore, this system can be quickly adapted and used to monitor future influenza pandemics and other major outbreaks of respiratory infectious disease, including novel pathogens.

  17. Information Technology and the Experience of Disorder

    Directory of Open Access Journals (Sweden)

    Jonathan Paul Marshall

    2012-11-01

    Full Text Available Information and communication technology (ICT is a prime modality of ordering in the contemporary world. However, order creates and needs its own disorder, and ICT has a long record of failing to deliver on its promises and creating the experience of disorder. This paper looks at the myths of ordering around ICT and then looks at people's experiences of ICT disorder. In particular it looks at three factors: the informal networks that develop because of problems with ICT and with ICT help; the failure of management and communication in hierarchy and finally the failure of requirements engineering to live up to its promise. This focus on disorder may suggest a new way of approaching the so-called ‘Information Society’.

    2000-01-01

    DCC is a new technology derived from FCC for propylene production. The propylene yields can reach 23m% with paraffinic feed and around 17m% with intermediate base feed. A portion of DCC cracked naphtha recycled in a commercial unit resulted in a propylene yield increment of 3.5m% at some expense of naphtha. The total BTX in the 75 - 150℃ naphtha fraction was 57. 6v%, in which toluene and xylenes were 21.9v% and 30.3v%, respectively. DCC catalyst consists of a modified mesopore zeolite with pentasil structure for primary product of naphtha range to undergo secondary cracking for producing light olefins. A series of DCC catalysts was formulated for various objectives, such as maximum propylene, maximum isoolefins, and metal tolerance for residual oil processing, etc. Seven commercial units have been put into production since 1990 inside and outside China, in which three of them were revamped from existing FCCUs, and the other four were grassroots units including a 750kt/a unit in TPI Company, Thailand. Currently, the TPI unit is running in full design capacity with about 40m% of atmospheric residual oil in the feedstock. Although the feedstock is much heavier than design, the propylene yield still keeps around the design value. The commercial experiences of some units are presented.

    This study examined the relations of preservice science teachers' attitudes towards technology use, technology ownership, technology competencies, and experiences to their self-efficacy beliefs about technological pedagogical content knowledge (TPACK). The present study also investigated interrelations among preservice teachers' attitudes towards technology use, technology ownership, technology competencies, and experiences. The participants of study were 665 elementary preservice science teachers (467 females, 198 males) from 7 colleges in Turkey. The proposed model based on educational technology literature was tested using structural equation modeling. The model testing results revealed that preservice teachers' technology competencies and experiences mediated the relation of technology ownership to their TPACK self efficacy beliefs. The direct relation of their possession of technology to their TPACK self efficacy beliefs was insignificant while the indirect relation through their technology competencies and experiences was significant. The results also indicated there were significant direct effects of preservice teachers' attitudes towards technology use, technology competencies, and experiences on their TPACK self efficacy beliefs.

  19. Microsatellite variability of Sardinian pine martens, Martes martes.

    Colli, Licia; Cannas, Rita; Deiana, Anna M; Tagliavini, James

    2011-08-01

    The pine marten, Martes martes, is a medium-sized terrestrial carnivore associated with woodland habitats of the western Palearctic region. The present distribution area of the species also includes six islands of the western Mediterranean basin. The origin of these insular populations and their taxonomic status are still debated; their molecular characterization appears relevant for conservation purposes. To describe the genetic variability of the pine martens from Sardinia we characterized 40 insular and 14 Italian individuals at seven nuclear microsatellite loci. The identification of private alleles and the calculated F(ST) value of 0.074 revealed some genetic differentiation between the two populations, which accounts for the high percentages of correct allocation (96.39-98.80%) scored by the genotype assignment test. The presence of two distinct clusters corresponding to Sardinia and mainland Italy was further confirmed by the multivariate Factorial Correspondence Analysis of individual genotypes. Moreover, the genome of the Sardinian individuals bore signs of past demographic fluctuations, i.e. the presence of the monomorphic locus Ma-4, a lower allelic richness and a lower number of private alleles, which may derive from the combination of drift, founder effects, and human overexploitation. Anyway, if such events ever affected the Sardinian population, this is likely to have happened in the past since, according to our microsatellite data, the present-day population does not show evidence of recent bottlenecks or inbreeding, the Wilcoxon sign-rank test and the F(IS) index being not statistically significant (both P > 0.05). Based on this genetic evidence, we advance hypotheses about the distinctiveness of the Sardinian population and its significance for taxonomy and conservation.

    The large helical device (LHD), which is the world largest helical confinement system, is a national project serving Japanese fusion community. In LHD, experiments of 7000 shots are carried out for 250 proposals every year. Efficient experiment arrangement is required in order to carry out many collaborators' proposal. Sometimes collaborators who are not familiar to LHD stay at NIFS only a few day to join the experiment. Issues are as follows: how to reduce collaborator's effort, how to reduce manager's effort to optimize the schedule; how to publicize plan and results of the experiment. We have developed web systems of virtual printer, experimental proposal and scheduling by using Ruby on Rails (RoR), which encapsulates relational data base (RDB) and AJAX. RDB enables to make tables by searching and sorting data with key words. Web servers are equipped in the virtual computer system in order to minimize efforts and cost of maintenance. The LHD web portal has been also developed in order to provide collaborators an efficient and intuitive interface to access the above systems, to take LHD information, and to use tools for LHD data analysis. The web systems have reduced collaborators' and managers' efforts significantly.

    Full Text Available As the inheritor of Chinese civilization, the National Palace Museum (hereafter referred to as the NPM, houses a world-class collection of cultural art and artifacts. Since the NPM began promoting the National Digital Archives Project in 2002, its efforts have expanded to develop a digital museum and various e-learning programs. Extending the use of digital archives to its educational and cultural industrial endeavors, the NPM has maximized the value of its exhibitions, publications, and educational programs.  In 2013, the NPM integrated creative thinking and interdisciplinary technologies, such as floating projection, augmented reality, and other sensory interactive media, to recreate the historical circumstance of 19th century East Asian maritime cultures in “Rebuilding the Tong-an Ships—New Media Art Exhibition," which opened at Huashan 1914 Creative Park and later won the Gold Award at the 2014 Digital Education Innovation Competition. Through a thorough exploration of the factors contributing to the success of "Rebuilding the Tong-an Ships," this study has isolated the two main factors of the exhibition’s popularity, namely, the compactness of the metadata and the atmosphere created by the interactive display technology.

E. crassipes Mart is grounded into meal and solidly fermented by mixing minerals and Trichoderma harzianum for 4 days at room temperature. The fermentation resulted the increase of nutritional value. The crude protein increases for 61.81% (from 6.31 to 10.21% and crude fiber decreases for 18% (26.61 to 21.82%. The in vivo experiment was conducted based on completely randomized design using 80 day old broiler chicks with 5 replication. They were alotted to 4 diets containing one control without fermented E. crassipes Mart, 5, 10 and 15% of fermented E. crassipes Mart. Diets were fed ad libitum for 6 weeks. Feed intake, weight gain and feed conversion ratio, carcas and abdominal fat were observed as parameters. Result showed that no parameter were significantly affected by treatments, although the nutritional values were slightly decreasing in higher fermented E. crassipes. The fermented E. Crassipes Mart can be used up to 15% in broiler rations.

    This essay explores the relationship between commerce and culture in the context of the recent debate over the social effect of Wal-Mart. In spite of much public debate, little is known about how Wal-Mart affects values. Using data collected from multiple sources, we show there is little evidence that Wal-Mart makes communities more conservative or more progressive.

    2011-01-01

    As a concern with the reliability and mass of current optical links in LHC experiments, we are investigating CW lasers and light modulators as an alternative to VCSELs. In addition we are developing data links in air, utilizing steering by MEMS mirrors and optical feedback paths for the control loop. Laser, modulator, and lens systems used are described, as well as two different electronic systems for a free space steering feedback loop. Our prototype system currently operates at 1.25 Gb/s, but could be upgraded. This link works over distances of order meters. Such links might enable one to move communication lasers (e.g. VCSELs) and optical fibers out of tracking detectors, for reasons such as reliability and power consumption. Some applications for free space data links, such as local triggering and data readout and trigger-clock distribution and links for much longer distances are also discussed.

    Full Text Available Este trabajo expone y examina los cambios de percepción que experimentó José Martí sobre el papel de los pueblos originarios de América, entre 1875 y 1878, años en los que vivió en México y Guatemala, con intensa escala en Yucatán, lugares donde conoció directamente la cultura y el pueblo maya. Martí resume una visión inicial de nuestra América en la figura lítica de Chacmool cuando después de ser expropiada por el gobierno yucateco, el Apóstol cubano la admira en la ciudad de Mérida y expresa que es la síntesis de las culturas americanas. Aspecto poco estudiado en la obra de Martí es este acercamiento etnográfico a la realidad maya de Yucatán y Guatemala.   This paper aims at presenting and examining the change of perception José Martí underwent in relation to the role of the native peoples of America between 1875 and 1878, the years he lived in Mexico and Guatemala, during which he spent a large amount of time in Yucatan, where he was able to get to know the Mayan culture and its people first hand. Martí summarized his initial vision of our America in the lithic figure of Chacmool, which he was able to admire in the city of Merida, after it had been expropriated by the government of Yucatan. The Cuban apostle described this as a synthesis of American cultures. This ethnographic insight into the Mayan reality in Yucatan and Guatemala represents a scarcely explored aspect of Martí's work.

    Full Text Available The Internet and computer technology have altered the education landscape. Online courses are offered throughout the world. Learning about the experiences of faculty members is important to guide practitioners and administrators. Using qualitative research methodology, this study investigated the experiences of faculty members teaching online courses. A convenience sampling was used to select the instructional technology faculty members to investigate their experiences in online courses. Semi-structured interviews with faculty members teaching online courses were used as the primary source to collect data about the experiences of faculty members in online courses. Results of the study showed that faculty members' interest in using technology and the amount of time available to them for online course design affected the quality of online courses. The findings of this study also indicated that design quality of online courses is affected by the interest of faculty members to use the technology and the time that they can devote to planning, designing, and developing online courses. The poor design of existing online courses, high learning expectations of ndividuals from these courses, and the future of online courses are the concerns of faculty members. Higher education institutions should support workshops and trainings to increase the skills and interests of non-instructional design faculty members to design and develop online courses.

    1989-01-01

    The COLD-SAT spacecraft will perform subcritical liquid hydrogen storage and transfer experiments under low-gravity conditions to provide engineering data for future space transportation missions. Consisting of an experiment module mated to a spacecraft bus, COLD-SAT will be placed in an initial 460 km circular orbit by an Atlas I commercial launch vehicle. After deployment, the three-axis-controlled spacecraft bus will provide electric power, experiment control and data management, communications, and attitude control along with propulsive acceleration levels ranging from 10 (-6) to 10(-4) g. These accelerations are an important aspect of some of the experiments, as it is desired to know the effects that low gravity levels might have on the heat and mass transfer processes involved. The experiment module will contain the three liquid hydrogen tanks, valves, pressurization equipment, and instrumentation. At launch all the hydrogen will be in the largest tank, which has helium-purged MLI and is loaded and topped off by the hydrogen tanking system used for the Centaur upper stage of the Atlas. The two smaller tanks will be utilized in orbit for performing some of the experiments. The experiments are grouped into two classes on the basis of their priority, and include six regarded as enabling technology and nine regarded as enhancing technology.

    Image quality is a concept that for long very well served to optimize display performance and signal quality. New technological developments, however, forced the community to look into higher-level concepts to capture the full experience. Terms as naturalness and viewing experience were used to optimize the full experience of 3D-displays and Ambilight TV. These higher-level concepts capture differences in image quality and differences in perceived depth or perceived viewing field. With the introduction of solid-state lighting, further enhancing the multimedia experience, yet more advanced quality evaluation concepts to optimize the overall experience will be needed in the future.

    In order to understand the processes governing the production of marine aerosols, repeatable, controlled methods for their generation are required. A new system, the miniature Marine Aerosol Reference Tank (miniMART), has been designed after the success of the original MART system, to approximate a small oceanic spilling breaker by producing an evolving bubble plume and surface foam patch. The smaller tank utilizes an intermittently plunging jet of water produced by a rotating water wheel, into an approximately 6 L reservoir to simulate bubble plume and foam formation and generate aerosols. This system produces bubble plumes characteristic of small whitecaps without the large external pump inherent in the original MART design. Without the pump it is possible to easily culture delicate planktonic and microbial communities in the bulk water during experiments while continuously producing aerosols for study. However, due to the reduced volume and smaller plunging jet, the absolute numbers of particles generated are approximately an order of magnitude less than in the original MART design.

  1. Utilizing HPC Network Technologies in High Energy Physics Experiments

    CERN Document Server

    AUTHOR|(CDS)2088631; The ATLAS collaboration

    2017-01-01

    Because of their performance characteristics high-performance fabrics like Infiniband or OmniPath are interesting technologies for many local area network applications, including data acquisition systems for high-energy physics experiments like the ATLAS experiment at CERN. This paper analyzes existing APIs for high-performance fabrics and evaluates their suitability for data acquisition systems in terms of performance and domain applicability. The study finds that existing software APIs for high-performance interconnects are focused on applications in high-performance computing with specific workloads and are not compatible with the requirements of data acquisition systems. To evaluate the use of high-performance interconnects in data acquisition systems a custom library, NetIO, is presented and compared against existing technologies. NetIO has a message queue-like interface which matches the ATLAS use case better than traditional HPC APIs like MPI. The architecture of NetIO is based on a interchangeable bac...

  7. Performance of active vibration control technology: the ACTEX flight experiments

    Science.gov (United States)

    Nye, T. W.; Manning, R. A.; Qassim, K.

    1999-12-01

    This paper discusses the development and results of two intelligent structures space-flight experiments, each of which could affect architecture designs of future spacecraft. The first, the advanced controls technology experiment I (ACTEX I), is a variable stiffness tripod structure riding as a secondary payload on a classified spacecraft. It has been operating well past its expected life since becoming operational in 1996. Over 60 on-orbit experiments have been run on the ACTEX I flight experiment. These experiments form the basis for in-space controller design problems and for concluding lifetime/reliability data on the active control components. Transfer functions taken during the life of ACTEX I have shown consistent predictability and stability in structural behavior, including consistency with those measurements taken on the ground prior to a three year storage period and the launch event. ACTEX I can change its modal characteristics by employing its dynamic change mechanism that varies preloads in portions of its structure. Active control experiments have demonstrated maximum vibration reductions of 29 dB and 16 dB in the first two variable modes of the system, while operating over a remarkable on-orbit temperature range of -80 °C to 129 °C. The second experiment, ACTEX II, was successfully designed, ground-tested, and integrated on an experimental Department of Defense satellite prior to its loss during a launch vehicle failure in 1995. ACTEX II also had variable modal behavior by virtue of a two-axis gimbal and added challenges of structural flexibility by being a large deployable appendage. Although the loss of ACTEX II did not provide space environment experience, ground testing resulted in space qualifying the hardware and demonstrated 21 dB, 14 dB, and 8 dB reductions in amplitude of the first three primary structural modes. ACTEX II could use either active and/or passive techniques to affect vibration suppression. Both experiments trailblazed

    SMART-1, the first European mission to the Moon, hosts 10 Technology and science experiments run by 7 on-board instruments. The primary objective of the mission is the demonstration of the solar electric propulsion. Therefore the monitoring of the spacecraft plasma environment and the contamination produced by the Stationary Plasma thruster is a key-task, which will be carried out by two experiments (SPEDE - Spacecraft Potential, Electron and Dust Experiment - and EPDP - Electric propulsion diagnostic Package). SPEDE and EPDP will contribute also to the characterisation of the near-Earth and interplanetary plasma environment and to study the solar wind. A package of three spectroscopy and imaging instruments has been selected to run technology demonstration of miniaturised compact instrument for planetary remote sensing and for carrying out valuable science at the Moon. AMIE (Asteroid-Moon micro-Imager Experiment) is a miniature medium-resolution (30 m at 300 km height) camera, equipped with a fixed panchromatic and 3-colour filter, for Moon topography and imaging support to other experiments.

    2007-01-01

    This report examines two important generic photovoltaic technologies at particularly revealing stages of development, i.e., the stages between R&D and stable commercial production and profitable sales. Based on two historical cases, it attempts to shed light on the difference between: (1) costs and schedules validated by actual manufacturing and market experience, and (2) estimated costs and schedules that rely on technology forecasts and engineering estimates. The amorphous Silicon case also identifies some of the costs that are incurred in meeting specific market requirements, while the Cadmium Telluride case identifies many of the operational challenges involved in transferring R&D results to production. The transition between R&D and commercial success takes a great deal of time and money for emerging energy conversion technologies in general. The experience reported here can be instructive to those managing comparable efforts, and to their investors. It can also be instructive to R&D managers responsible for positioning such new technologies for commercial success.

  10. Evaluation of technology transferring: The experiences of the first Navy Domestic Technology Transfair. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1989-12-31

    In August 1989 the Office of the Chief of Naval Research and the American Defense Preparedness Association conducted the first Navy Domestic Technology Transfair. The objective of the Transfair was to expose the US Navy`s years of solid experience across a broad span of technology to organizations outside of the Navy. It was an opportunity for private industry to capitalize on the Navy developed technology and this opening for industry was the primary focus of the Transfair. The event provided a unique forum to meet leading Navy scientific and engineering innovators face-to-face. Information was available concerning licensing of naval technology that was for sale to the private sector. Further, discussions covered opportunities for new cooperative research and development agreements with Navy laboratories and R&D activities. These agreements were authorized under the Federal Technology Transfer Act of 1986. The Transfair program was conducted in such a manner as to allow each Navy inventor, either scientist or engineer, to present a system, piece of hardware, or licensable concept in a formal paper presentation. Then, the Navy inventors were available in two, two-hour periods in which individual discussions were conducted, with attendees pursuing specific venues of cooperative agreements as desired. This report provides specifics concerning the technologies that were made available for transfer to the private sector during the Transfair. The Transfair concept sought to add special emphasis to the opening that the 1988 Technology Transfer Act brought to the marketplace. The experience was a step in the education of the possibilities for cooperation between the government and the private sector to share technology. Of additional significance is the economic enhancement for business expansion with the application of the technology to markets beyond defense.

  11. Students' Perceptions of and Experiences With Educational Technology: A Survey.

    2016-05-18

    It is generally assumed that incoming students in medical education programs will be better equipped for the "digital age" given their younger age and an educational upbringing in which technology was seemingly omnipresent. In particular, many assume that today's medical students are more likely to hold positive attitudes and increased comfortability with technology and possess greater information technology (IT) skills. The purpose of this study was to compare responses of incoming veterinary medical students to a series of IT-related questions contained in a common questionnaire over the course of a 10-year period (2005-2015) to discern whether students' attitudes have improved and uses and comfortability with technology have increased as anticipated. A survey measuring attitudes and preferences, computing experience, and technology ownership was administered each year for the past 10 years to incoming veterinary medical students at a large veterinary school in the United States. Students' responses to survey items were compared at 3 data points (2005, 2010, and 2015). Today's incoming veterinary medical students tend to indicate the same desire to improve skills using spreadsheets and web page design as incoming students from 10 years ago. It seems that despite technological advances and increased exposure to such applications and skills, there remains a challenge for students to "keep up" with the ever evolving technology. Moreover, although students continue to report they are very comfortable with using a computer (and related devices), many use their computers as typewriters or word processors, as opposed to a means for performing more advanced computing functions. In general, today's medical students are not expert computer users as many assume. Despite an upbringing in a digitized world, many students still lack many basic computing skills.

    2017-05-01

    To evaluate the effectiveness of Internet filtering tools designed to shield adolescents from aversive experiences online. A total of 1030 in-home interviews were conducted with early adolescents aged from 12 to 15 years (M = 13.50, SD = 1.18) and their caregivers. Caregivers were asked about their use of Internet filtering and adolescent participants were interviewed about their recent online experiences. Contrary to our hypotheses, policy, and industry advice regarding the assumed benefits of filtering we found convincing evidence that Internet filters were not effective at shielding early adolescents from aversive online experiences. Preregistered prospective and randomised controlled trials are needed to determine the extent to which Internet filtering technology supports vs thwarts young people online and if their widespread use justifies their financial and informational costs.

    Over the next three years the research program of the Heavy Ion Fusion Virtual National Laboratory (HIF-VNL), a collaboration among LBNL, LLNL, and PPPL, is focused on separate scientific experiments in the injection, transport and focusing of intense heavy ion beams at currents from 100 mA to 1 A. As a next major step in the HIF-VNL program, we aim for a complete ''source-to-target'' experiment, the Integrated Beam Experiment (IBX). By combining the experience gained in the current separate beam experiments IBX would allow the integrated scientific study of the evolution of a single heavy ion beam at high current ({approx}1 A) through all sections of a possible heavy ion fusion accelerator: the injection, acceleration, compression, and beam focusing. This paper describes the main parameters and technology choices of the planned IBX experiment. IBX will accelerate singly charged potassium or argon ion beams up to 10 MeV final energy and a longitudinal beam compression ratio of 10, resulting in a beam current at target of more than 10 Amperes. Different accelerator cell design options are described in detail: Induction cores incorporating either room temperature pulsed focusing-magnets or superconducting magnets.

    2004-01-01

    The environment on the surface of Mars is different in several critical ways from the orbital environment in which space solar arrays normally operate. Some important differences are: 1) Low intensity, low temperature operation; 2) Spectrum modified by atmospheric dust, varies with time; 3) Indirect sunlight; 4) Possibility of dust atoms at some times of year; 5) Deposited dust; 6) Wind; 7) Peroxide-rich reactive soil. We are developing two experiments to test operation of solar arrays on the surface of Mars, to be flown on the 2001 Surveyor Lander mission. The Mars Array Technology Experiment (MATE) will test the operation of several types of solar cells under Mars conditions, and determine the direct and scattered solar spectrum at the surface. The Dust Accumulation and Removal Technology (DART) experiment will monitor the amount of dust deposition on a target solar cell, measure the characteristics of the dust, and test the feasibility of dust removal.

    1990-08-01

    For more than 10 years the conventional media for High Energy Physics has been 9 track magnetic tape in various densities. More recently, especially in Europe, the IBM 3480 technology has been adopted while in the United States, especially at Fermilab, 8 mm is being used by the largest experiments as a primary recording media and where possible they are using 8 mm for the production, analysis and distribution of data summary tapes. VHS and Digital Audio tape have recurrently appeared but seem to serve primarily as a back-up storage media. The reasons for what appear to be a radical departure are many. Economics (media and controllers are inexpensive), form factor (two gigabytes per shirt pocket), and convenience (fewer mounts/dismounts per minute) are dominant among the reasons. The traditional data media suppliers seem to have been content to evolve the traditional media at their own pace with only modest enhancements primarily in ``value engineering'' of extant products. Meanwhile, start-up companies providing small system and workstations sought other media both to reduce the price of their offerings and respond to the real need of lower cost back-up for lower cost systems. This happening in a market context where traditional computer systems vendors were leaving the tape market altogether or shifting to ``3480'' technology which has certainly created a climate for reconsideration and change. The newest data storage products, in most cases, are not coming from the technologies developed by the computing industry but by the audio and video industry. Just where these flopticals, opticals, 19 mm tape and the new underlying technologies, such as, ``digital paper'' may fit in the HEP computing requirement picture will be reviewed. What these technologies do for and to HEP will be discussed along with some suggestions for a methodology for tracking and evaluating extant and emerging technologies.

This poetry has been regarded by critics as linked to historical realism, and in our opinión consitutes the literary consolidation of the Roda de Ter-born poet after his his apprenticeship in existential poetry. Throughout five books and a long poem, the authorembodies a double social dimensión in his verse: on the one hand, extemal and collective history, especially achieved through the universe of the village and the factory; on the other hand, the inner and personal history dealing with aspects of his most intérnate experience in themes such as love or the function of poetry.  Paraules clau: Miquel Martí i Pol; poesia existencial; poesia catalana contemporània

  17. Multiple Payload Ejector for Education, Science and Technology Experiments

    Lechworth, Gary

    2005-01-01

    The education research community no longer has a means of being manifested on Space Shuttle flights, and small orbital payload carriers must be flown as secondary payloads on ELV flights, as their launch schedule, secondary payload volume and mass permits. This has resulted in a backlog of small payloads, schedule and cost problems, and an inability for the small payloads community to achieve routine, low-cost access to orbit. This paper will discuss Goddard's Wallops Flight Facility funded effort to leverage its core competencies in small payloads, sounding rockets, balloons and range services to develop a low cost, multiple payload ejector (MPE) carrier for orbital experiments. The goal of the MPE is to provide a low-cost carrier intended primarily for educational flight research experiments. MPE can also be used by academia and industry for science, technology development and Exploration experiments. The MPE carrier will take advantage of the DARPAI NASA partnership to perform flight testing of DARPA s Falcon small, demonstration launch vehicle. The Falcon is similar to MPE fiom the standpoint of focusing on a low-cost, responsive system. Therefore, MPE and Falcon complement each other for the desired long-term goal of providing the small payloads community with a low-cost ride to orbit. The readiness dates of Falcon and MPE are complementary, also. MPE is being developed and readied for flight within 18 months by a small design team. Currently, MPE is preparing for Critical Design Review in fall 2005, payloads are being manifested on the first mission, and the carrier will be ready for flight on the first Falcon demonstration flight in summer, 2006. The MPE and attached experiments can weigh up to 900 lb. to be compatible with Falcon demonstration vehicle lift capabilities fiom Wallops, and will be delivered to the Falcon demonstration orbit - 100 nautical mile circular altitude.

    Highlights: • The integration of two frameworks for real-time control and data acquisition is described. • The integration may significantly fasten the development of system components. • The system includes also a code generator for the integration of code written in Simulink. • A real-time control systemcan be implemented without the need of writing any line of code. - Abstract: Simulink is a graphical data flow programming tool for modeling and simulating dynamic systems. A component of Simulink, called Simulink Coder, generates C code from Simulink diagrams. MARTe is a framework for the implementation of real-time systems, currently in use in several fusion experiments. MDSplus is a framework widely used in the fusion community for the management of data. The three systems provide a solution to different facets of the same process, that is, real-time plasma control development. Simulink diagrams will describe the algorithms used in control, which will be implemented as MARTe GAMs and which will use parameters read from and produce results written to MDSplus pulse files. The three systems have been integrated in order to provide a tool suitable to speed up the development of real-time control applications. In particular, it will be shown how from a Simulink diagram describing a given algorithm to be used in a control system, it is possible to generate in an automated way the corresponding MARTe and MDSplus components that can be assembled to implement the target system.

    Full Text Available Combretum leprosum Mart. is a tree species native of the Caatinga, used in the restoration of degraded areas and in folk medicine. Thus, this research aimed to evaluate the germination and vigor of the seeds subjecting them to different pre-germinative treatments, temperatures and substrates. In the first experi- ment, we tested the pre-germinative treatments: mechanical scarification with sandpaper, chemical scarification with H2SO4 for 1, 5, 10 and 20 minutes, immersion in water at 80 oC and imbibition in distilled water for 24 hours, beyond of the control. In the second experiment, after treatment of imbibition in water for 24 hours, the experimental design was completely randomized in a factorial 5 x 4 (five substrates: into paper, sand, coconut fiber, vermiculite and paper towel organized in the form of rolls; and four temperatures: 25, 30, 35 and 20-30 oC. The following parameters were evalueted: seed moisture content, germination, germination speed index, first germination count and seedling length and dry matter weight. The seeds of Combretum leprosum have not coat dormancy. However, pre-germinative treatments of mechanical scarification with sandpaper and imbibi- tion in water for 24 hours allows better expression of seeds vigor. The paper towel and the temperatures of 25, 30 and 20-30 oC provide adequate conditions for evaluating the germination of Combretum leprosum seeds.

    The exhaustion of fuel-energy resources became an evident problem of the European continent in the 1960s. Careful utilization of their own reserves of coal, oil, and gas (Germany, France, Spain) and assigned shares of imports of these resources make up the strategy of economic development of the European countries. The expansion of oil shale utilization is the most topical problem. The experience of mining oil shale deposits in Estonia and Russia, in terms of the practice and the economic results, is reviewed in this article. The room-and-pillar method of underground mining and the open-cut technology of clearing the ground ensure the fertility of a soil. The economics of underground and open pit oil shale mines is analyzed in terms of natural, organizational, and technical factors. These analyses are used in the planning and management of oil shale mining enterprises. The perspectives of the oil shale mining industry of Estonia and the economic expediency of multiproduction are examined. Recommendations and guidelines for future industrial utilization of oil shale are given in the summary.

    Full Text Available Information technology has become an ally of the corporate world, making available communications infrastructures that generate large volumes of information. To store it, databases ¿ in particular, data marts, have been deployed to store selected information. However, the scenarios obtained from data marts were not up-to-date, there being a time lag; the time between the occurrence of an event and the execution of an action or response was considerable. Minimizing time latency (zero latency has become a challenge. The objective of this study was to analyze the advantages of applying zero latency in supporting decision making in a commercial data mart of a company in the construction business. We proposed a zero latency data mart for the extraction of scenarios to support decision making. The analyses show that the need has been met with the extractions performed on the proposed data mart.

    2003-10-01

    Full Text Available La martora, Martes martes, è un mustelide storicamente presente su gran parte del territorio italiano, soprattutto dove siano presenti foreste mature altamente strutturate e ricche di risorse. Nel corso dei decenni passati, cause quali la deforestazione con conseguente frammentazione dell'habitat, la caccia e la persecuzione da parte dell'uomo hanno portato ad un sensibile declino sia nel numero d'individui sia di popolazioni in tutta l'Europa. Frammentazione degli areali e diminuzione del numero di soggetti costituiscono le cause principali di un limitato flusso genico con conseguente formazione di popolazioni isolate di martora e perdita di variabilità genetica (Kyle et al., 2003. Per queste ragioni la martora risulta attualmente tutelata secondo quanto previsto dalla Convenzione di Berna (appendice III e dalla Direttiva europea 92/43/CEE "Habitats & Species". Di fronte a prospettive di tipo conservazionistico, diventa necessario disporre di metodologie per la valutazione della variabilità residua nella specie a livello d'individui e di popolazioni. Secondo numerosi Autori, i microsatelliti costituiscono marcatori molto efficaci nella descrizione della struttura genetica e della storia demografica di specie (Beaumont & Bruford, 1999; Linares, 1999. Il presente lavoro propone i risultati ottenuti attraverso il confronto di due campioni costituiti da individui di Martes martes provenienti dalla Sardegna (25 esemplari e dal territorio italiano (6 esemplari. L'analisi è stata condotta a livello di 7 loci microsatellitari dinucleotidici polimorfici. Il valore di FST calcolato dal confronto dei due gruppi è risultato pari a 0,102 e ricade nel range di variazione identificato di recente in popolazioni nord-europee di martora (Kyle et al., 2003. L'analisi della varianza molecolare (AMOVA, condotta a due livelli gerarchici, ha permesso in particolare di ripartire la varianza del campione

    Full Text Available Research on technology use and access among youth raised in non-traditional family structures indicates that the youth’s experiences are different from individuals raised in traditional family structures. Foster care represents a non-traditional family structure that warrants research attention in terms of technology. Using a multicultural feminist framework, the present study explores the past and present technological experience of a woman (30 years old who was raised in the foster care system. The results are presented as a case study documenting her technological experience in foster care, as she transitioned out of the foster care system, and as she has taken on the roles of wife and mother. Results indicated that the participant had limited access to technology while in the foster care system, and this limited technology access related to her current use and perceptions of technology. Directions for future research are provided.

  8. The effects of phosphate supply on growth of plants from the Brasilian Cerrado: experiments with seedlings of the annual weed, Bidens gardneri Baker (Compositeae) and the tree, Qualea grandiflora (Mart.) (Vochysiaceae).

    1990-01-01

    Plants of the cerrado tree species Qualea grandiflora and the annual herb Bidens gardneri were grown from seed in controlled environment rooms at 30/20° C and 12 hour photoperiod. Seedlings were grown in pots or small tubes containing sand and provided with various amounts of mineral solutions based on the formulation of Hoagland and Arnon but with the phosphate content modified in some cases. In a long-term experiment lasting 213 days, plants supplied with full strength Hoagland's solution all died but plants of Qualea given 1/10 strength solution survived, although they grew very slowly. Low relative growth rates (0.008-0.036 d(-1)) were also a feature of other experiments with Qualea and calculated rates of net assimilation rate gave values of 3-7 mg CO2 dm(-2) h(-1). Expansion of the photosynthetic surface proceeded slowly and the cotyledons were the main site of photosynthesis for more than 40 days. The low rates of growth occurred despite significant uptake of phosphorus by young plants and in shortterm experiments growth was independent of the amount of phosphate supplied and accumulated. In contrast, the values of R found for plants of Bidens reached 0.24 d(-1). Growth of young plants was dependent on the external supply of phosphorus, being reduced when this was low and also when it was very high. Growth of the photosynthetic surface was also much more rapid than for Qualea and also varied with supply of phosphorus. The results are discussed in the context of the occurrence of these species in the Cerrado.

    Full Text Available Qualea grandiflora Mart. (Vochysiaceae, commonly known as "pau-terra", is an arborous species native to the Brazilian savannah which possess commercial interests, as it can be used either as an ornamental or as a medicinal plant. "Pau-terra" can also be used in the heterogeneous reforestation of areas which are destined for restoration of permanent preservation degraded areas. Propagation studies with this species are scarce, being necessary then further clarification regarding the factors that influences the germination process. In this context, the objective of this work was to evaluate the influence of different temperatures, substrates and light conditions on seed germination. We selected light brown seeds which were subjected to different interactions between temperatures (15-25, 20-30, 25 and 30°C, substrate (paper, sand and vermiculite and light (light and dark. All seeds were later dry-incubated at 32°C for 3, 6 and 12 hours. After treatments, seeds were kept in BOD at 58% RH and the following parameters were calculated: germination (%G and germination speed index (GSI; the formation of normal and abnormal seedlings and the number dead seeds. Interaction was observed for all variables. In the optimum temperature range, the seeds behaved as photoblastic neutral or indifferent. Under alternating temperatures, darkness enhanced the germination, especially when combined with the lower temperatures. We noted that the sowing in sand, at 25°C, allowed the maintenance of suitable combinations of germination and seedling development. With respect to desiccation tolerance, "pau-terra" seeds presented an orthodox behavior, with a linear increase of the vigor as function of drying.

    Full Text Available Although the architectural heritage is of considerable importance in Italy, we often encounter critical conditions that perpetuate emergencies rather than efficiency. Those working in this field complain of poor resources, procedural hitches and clashing skills. Visitors encounter indecorous or risky conditions, difficulty of use and an unsatisfactory integration with the socio-economic sphere. Methodological instruments of Architectural Technology are essential in order to tackle these critical conditions, which are most prominent in the borderline cases of archaeological sites, because of the clear break with contemporary life and the intrinsic vulnerability of archaeological structures. Although they are related to immaterial technology, these tools produce tangible effects, occasioning reliability in every intervention. The operational aspects are intermingled with the wider issues of quality and effectiveness of process with reference to the public client.

    2006-01-01

    For people with disabilities, work remains the best route to independence and enacting one's own choices. Assistive technology (AT) is often crucial in removing barriers to employment, and in enabling workers with disabilities to work more productively. A participatory action research project known as Community Research for Assistive Technology surveyed people with disabilities using Independent Living Centers throughout California, in part to identify barriers to employment and study use of job-related AT to overcome such barriers. Across disability groups, disability itself was cited as the primary barrier to employment, with potential loss of benefits and lack of education cited as secondary barriers. A majority of working respondents reported using assistive technology (such as adapted telephones, wheelchairs, magnifiers, and adapted computer equipment) or services to perform job functions. The vast majority of those using job-related AT reported substantial benefits to their productivity and self-esteem. Employees' requests for AT as a workplace accommodation were granted more often than not, but many other employees had to pay for their own workplace AT.

    2003-02-01

    This paper reports on an investigation into the first time implementation of a technology education unit of work by a beginning primary school teacher. The researchers monitored the teacher's implementation of the unit across a 6 week period using an interpretivist research approach. A variety of data sources were drawn upon including teacher and student interviews, video and audio recordings of small group and whole-class interactions, and student-developed artefacts. Providing appropriate learning activities to assist students to develop understanding about patterns and shapes incorporated into buildings and other structures to enhance strength and stability was a challenge faced by the beginning teacher. However, she drew support from a teaching resource, which provided guidance and structure for the teaching of technology concepts and processes related to strength and stability of structures and materials. The resource helped her to develop learning activities that were appropriate to the topic and to the needs of the students in her class. Implications of the study relate to the needs of teachers grappling with teaching design and technology for the first time and the support that they can gain from predetermined planning and teaching models and well-developed teaching resources.

    The COLD-SAT spacecraft design experiments are described. COLD-SAT will be placed into an initial 1300 km circular orbit by an Atlas commercial launch vehicle. Electric power, experiment control and data management, attitude control, and propulsive accelarations for the experiments will be provided by the three-axis-controlled spacecraft bus. To provide data on the effects that low gravity levels might have on the heat and mass transfer processes involved, low levels of accelaration will be created. The COLD-SAT experiment will be configured into a module. The spacecraft experiment module will include three liquid hydrogen tanks; fluid transfer, pressurization and venting equipment; and instrumentation. Since the largest tank has helium-purged MLI to prevent ingress and freezing of air on the launchpad, it will contain all the liquid hydrogen at the point of launching. The hydrogen tanking system used for the Centaur upper stage of the Atlas will load and top off this tank. Atlas, with its liquid hydrogen upper stage, large payload fairing, and large launch margin, simplifies COLD-SAT design and integration.

  12. La historia orbital de Deimos y la oblicuidad de Marte

    Science.gov (United States)

    Brunini, A.; Yokoyama, T.

    Recientemente, se ha demostrado mediante extensas integraciones numéricas, que la rotación de Marte pasó repetidamente por estados caóticos de movimiento, debido al pasaje por zonas de resonancia spin - órbita. En dichas circunstancias, la oblicuidad marciana pudo haber sufrido grandes excursiones de varias decenas de grados. Las consecuencias de dichas variaciones son de extrema importancia en el contexto de la búsqueda de manifestaciones de vida fósil en dicho planeta. El estudio de la dinámica orbital del satélite más exterior de Marte, Deimos, nos ha permitido comprobar, en el marco de las distintas teorías sobre su orígen, que la oblicuidad de Marte dificilmente pudo haber sufrido variaciones que la aparten más de 10o respecto de actual valor. Este resultado parece ser mucho más robusto que las simulaciones numéricas de Touma y Wisdom asi como las de Laskar y Robutel, lo que permite poner cotas más severas a la evolución paleoclimática de Marte.

    Java language has been demonstrated to be an effective tool in supporting medical image viewing in Russia. This evaluation was completed by obtaining a maximum of 20 images, depending on the client's computer workstation from one patient using a commercially available computer tomography (CT) scanner. The images were compared against standard CT images that were viewed at the site of capture. There was no appreciable difference. The client side is a lightweight component that provides an intuitive interface for end users. Each image is loaded in its own thread and the user can begin work after the first image has been loaded. This feature is especially useful on slow connection speed, 9.6 Kbps for example. The server side, which is implemented by the Java Servlet Engine works more effective than common gateway interface (CGI) programs do. Advantages of the Java Technology place this program on the next level of application development. This paper presents a unique application of Java in telemedicine.

    Companion diagnostics are used to aid clinical decision making to identify patients who are most likely to respond to treatment. They are becoming increasingly important as more new pharmaceuticals receive licensed indications that require the use of a companion diagnostic to identify the appropriate patient subgroup for treatment. These pharmaceuticals have proven benefit in the treatment of some cancers and other diseases, and also have potential to precisely tailor treatments to the individual in the future. However, the increasing use of companion diagnostics could place a substantial burden on health system resources to provide potentially high volumes of testing. This situation, in part, has led policy makers and Health Technology Assessment (HTA) bodies to review the policies and methods used to make reimbursement decisions for pharmaceuticals requiring companion diagnostics. The assessment of a pharmaceutical alongside the companion diagnostic used in the clinical trials may be relatively straightforward, although there are a number of challenges associated with assessing pharmaceuticals where a range of alternative companion diagnostics are available for use in routine clinical practice. The UK HTA body, the National Institute for Health and Care Excellence (NICE), has developed policy for considering companion diagnostics using its Technology Appraisal and Diagnostics Assessment Programs. Some HTA bodies in other countries have also adapted their policies and methods to accommodate the assessment of companion diagnostics. Here, we provide insight into the HTA of companion diagnostics for reimbursement decisions and how the associated challenges are being addressed, in particular by NICE.

  3. Immobilized cell technology in beer brewing: Current experience and results

    Directory of Open Access Journals (Sweden)

    Full Text Available Immobilized cell technology (ICT has been attracting continual attention in the brewing industry over the past 30 years. Some of the reasons are: faster fermentation rates and increased volumetric productivity, compared to those of traditional beer production based on freely suspended cells, as well as the possibility of continuous operation. Nowadays, ICT technology is well established in secondary fermentation and alcohol- free and low-alcohol beer production. In main fermentation, the situation is more complex and this process is still under scrutiny on both the lab and pilot levels. The paper outlines the most important ICT processes developed for beer brewing and provides an overview of carrier materials, bioreactor design and examples of their industrial applications, as well as some recent results obtained by our research group. We investigated the possible applications of polyvinyl alcohol in the form of LentiKats®, as a potential porous matrices carrier for beer fermentation. Given are the results of growth studies of immobilized brewer's yeast Saccharomyces uvarum and the kinetic parameters obtained by using alginate microbeads with immobilized yeast cells and suspension of yeast cells as controls. The results indicate that the immobilization procedure in LentiKat® carriers has a negligible effect on cell viability and growth. The apparent specific growth rate of cells released in medium was comparable to that of freely suspended cells, implying preserved cell vitality. A series of batch fermentations performed in shaken flasks and an air-lift bioreactor indicated that the immobilized cells retained high fermentation activity. The full attenuation in green beer was reached after 48 hours in shaken flasks and less than 24 hours of fermentation in gas-lift bioreactors.

    In this paper, we first discuss the notion that artificial market systems should meet the requirements of fidelity, transparency, reproducibility, and traceability. Next, we introduce history of development of the artificial market system named U-Mart system that meet the requirements well, which have been developed by the U-Mart project. We have already developed the U-Mart system called “U-Mart system version 3.0” to solve problems of old U-Mart systems. In version 3.0 system, trading process is modularized and universal market system can be easily introduced.However, U-Mart system version 3.0 only simulates the single brand futures market. The simulation of the plural brands and plural markets has been required by lot of users. In this paper, we proposed a novel U-Mart system called “U-Mart system version 4.0” to solve this problem of U-Mart system version 3.0. We improve the server system, machine agents and GUI in order to simulate plural brands and plural markets in U-Mart system version 4.0. The effectiveness of the proposed system is confirmed by statistical analysis of results of spot market simulation with random agents.

    The concept of sustainability is associated with the statement from the World Commission on Environment and Development, 1987: '...development that meets the needs and aspirations of the present without compromising the ability to meet those of the future...' However, this statement lacks a practical environmental management strategy. The goal of a sustainable management strategy is to promote the structure and operation of the human component of a system (society, economy, technology, etc.) in such a manner as to reinforce the persistence of the structures and operation of the natural component (i.e., the ecosystem). We report on our efforts to identify the characteristics of sustainable systems with a simulation model that comprises an ecological food web and a simple, abstract industrial sector. We consider three different industry types, each taking different combinations of inputs from agriculture, natural resource extraction and harvesting of a wild animal species. We explore several scenarios including halving industrial efficiency, doubling the throughput of the industrial process (IP), and doubling the wastefulness of production. We present the results with the aid of a summary measure based on information theory.

    The design of the Ignitor machine incorporates a series of solutions that allows it to produce plasma currents up to 11 MA with an adequate safety factor in a compact confinement configuration. The consequent record high poloidal magnetic pressures p_Mp=\\overline\\overlineB^2_p/(2μ_0) makes it possible to achieve ignition at low temperatures and to have a number of contained thermal particle orbits not inferior to that of much larger devices such as ITER-FEAT. In fact, the key parameter of merit for comparison among different machines(J.H. Schultz et al.,Advanced magnets and implications for BPX), BPS Workshop II (G.A. San Siego, CA, 2001) has been recognized to be of the type I_pAq_ψ/R_0, where Ip is the plasma current, A the aspect ratio, R0 the major radius and q_ψ the plasma safety factor. The combined technological solutions are the ''bucking and wedging" concept of the toroidal magnet, the adoption of compression rings, of a (horizontal) magnetic press, the He-subcooling of the (copper) coils and the splitting and grading of the central solenoid.

    Full Text Available We examine 4 different DON-toxin-containing (0.74 - 1.15 - 1.19 - 2.14 mg/kg winter wheat samples: they were debranned and undebranned, and we investigated the flour’s and the by-products’ (coarse, fine bran toxin content changes. SATAKE lab-debranner was used for debranning and BRABENDER lab-mill for the milling process. Without debranning, two sample flours were above the DON toxin limit (0.75 mg/kg, which are waste. By minimum debranning (and minimum debranning mass loss; 6-8%, our experience with whole flour is that the multi-stage debranning measurement significantly reduces the content of the flour’s DON toxin, while the milling by-products, only after careful consideration and DON toxin measurements, may be produced for public consumption and for feeding.

    Students' learning interests and attitudes toward science have both been studied for decades. However, the connection between them with students' life experiences about science and technology has not been addressed much. The purpose of this study is to investigate students' learning interests and life experiences about science and technology, and also their attitudes toward technology. A total of 942 urban ninth graders in Taiwan were invited to participate in this study. A Likert scale questionnaire, which was developed from an international project, ROSE, was adapted to collect students' ideas. The results indicated that boys showed higher learning interests in sustainability issues and scientific topics than girls. However, girls recalled more life experiences about science and technology in life than boys. The data also presented high values of Pearson correlation about learning interests and life experiences related to science and technology, and in the perspective on attitudes towards technology. Ways to promote girls' learning interests about science and technology and the implications of teaching and research are discussed as well.

    2015-07-01

    Direct measurements of charged cosmic radiation with instruments in Low Earth Orbit (LEO), or flying on balloons above the atmosphere, require the identification of the incident particle, the measurement of its energy and possibly the determination of its sign-of-charge. The latter information can be provided by a magnetic spectrometer together with a measurement of momentum. However, magnetic deflection in space experiments is at present limited to values of the Maximum Detectable Rigidity (MDR) hardly exceeding a few TV. Advanced calorimetric techniques are, at present, the only way to measure charged and neutral radiation at higher energies in the multi-TeV range. Despite their mass limitation, calorimeters may achieve a large geometric factor and provide an adequate proton background rejection factor, taking advantage of a fine granularity and imaging capabilities. In this lecture, after a brief introduction on electromagnetic and hadronic calorimetry, an innovative approach to the design of a space-borne, large acceptance, homogeneous calorimeter for the detection of high energy cosmic rays will be described.

    We analyze the effect of Wal-Mart's entry into the grocery market using a unique stor-level price panel data set. We use OLS and two IV specifications to estimate the effect of Wal-Mart's entry on competitors' prices of 24 grocery items across several categories. Wal-Mart's price advantage over competitors for these products averages approximately 10%. On average, competitors' response to Wal-Mart's entry is a price reduction of 1-1.2%, mostly due to smaller-scale competitors: the response...

    Understanding technology dynamics, a fundamental driving factor of the evolution of energy systems, is essential for sound policy formulation and decision making. Technological change is not an autonomous process, but evolves from a number of endogenous interactions within the social system. Technologies evolve and improve only if experience with them is possible. Efforts must be devoted to improve our analytical tools concerning the treatment given to the technological variable, recognising the cumulative and gradual nature of technological change and the important role played by learning processes. This report presents a collection of works developed by the authors concerning the endogenisation of technological change in energy optimisation models, as a contribution to the Energy Technology Dynamics andAdvanced Energy System Modelling Project (TEEM), developed in the framework of the Non Nuclear Energy Programme JOULE III of the European Union (DGXII). Here, learning curves, an empirically observed manifestation of the cumulative technological learning processes, are endogenised in two energy optimisation models. MARKAL, a widely used bottom-up model developed by the ETSAP programme of the IEA and ERIS, a model prototype, developed within the TEEM project for assessing different concepts and approaches. The methodological approach is described and some results and insights derived from the model analyses are presented. The incorporation of learning curves results in significantly different model outcomes than those obtained with traditional approaches. New, innovative technologies, hardly considered by the standard models, are introduced to the solution when endogenous learning is present. Up-front investments in initially expensive, but promising, technologies allow the necessary accumulation of experience to render them cost-effective.

  1. Gaming, texting, learning? Teaching engineering ethics through students' lived experiences with technology.

    2013-09-01

    This paper examines how young peoples' lived experiences with personal technologies can be used to teach engineering ethics in a way which facilitates greater engagement with the subject. Engineering ethics can be challenging to teach: as a form of practical ethics, it is framed around future workplace experience in a professional setting which students are assumed to have no prior experience of. Yet the current generations of engineering students, who have been described as 'digital natives', do however have immersive personal experience with digital technologies; and experiential learning theory describes how students learn ethics more successfully when they can draw on personal experience which give context and meaning to abstract theories. This paper reviews current teaching practices in engineering ethics; and examines young people's engagement with technologies including cell phones, social networking sites, digital music and computer games to identify social and ethical elements of these practices which have relevance for the engineering ethics curricula. From this analysis three case studies are developed to illustrate how facets of the use of these technologies can be drawn on to teach topics including group work and communication; risk and safety; and engineering as social experimentation. Means for bridging personal experience and professional ethics when teaching these cases are discussed. The paper contributes to research and curriculum development in engineering ethics education, and to wider education research about methods of teaching 'the net generation'.

    A specific research and development program has been carried out by BARC in India to develop the technology for large area silicon strip detectors for application in nuclear and high energy physics experiments. These strip detectors will be used as pre-shower detector in the CMS experiment at LHC, CERN for 0/ rejection. The fabrication technology to produce silicon strip detectors with very good uniformity over a large area of ∼ 40 cm2, low leakage currents of the order of 10 nA/cm2 per strip and high breakdown voltage of >500 V has been developed by BARC. The production of detectors is already under way to deliver 1000 detector modules for the CMS and 90% production is completed. In this paper, research and development work carried out to develop the detector fabrication technology is briefly described. The performance of the silicon strip detectors produced in India is presented. The present status of the detector technology is discussed.

    Full Text Available In this paper, I report on preservice teachers’ reflections and perceptions on theirproblem-solving process in a technological context. The purpose of the study was to to investigatehow preservice teachers experience working individually in a dynamic geometry environment andhow these experiences affect their own mathematical activity when integrating content (nonroutineproblems and context (technology environment. Careful analysis of participants’ perceptionsregarding their thinking while engaged in problem solving, provided an opportunity to explorehow they explain the emergence of problem solving when working in a dynamic geometryenvironment. The two participants communicated their experience both through the lenses ofthemselves as problem solvers and as future mathematics educators. Moreover, the results of thestudy indicated that problem solving in a technology environment does not necessarily allow focuson decision-making, reflection, and problem solving processes as reported by previous research.

    Little is known about patients' and carers' experiences of interacting with home haemodialysis (HHD) technology, in terms of user experience, how the design of the technology supports safety and fits with home use, and how the broader context of service provision impacts on patients' use of the technology. Data were gathered through ethnographic observations and interviews with 19 patients and their carers associated with four different hospitals in the UK, using five different HHD machines. All patients were managing their condition successfully on HHD. Data were analysed qualitatively, focusing on themes of how individuals used the machines and how they managed their own safety. Findings are organised by three themes: learning to use the technology, usability of the technology, and managing safety during dialysis. Home patients want to live their lives fully, and value the freedom and autonomy that HHD gives them; they adapt use of the technology to their lives and their home context. They also consider the machines to be safe; nevertheless, most participants reported feeling scared and having to learn through mistakes in the early months of dialysing at home. Home care nurses and technicians provide invaluable support. Although participants reported on strategies for anticipating problems and keeping safe, perceived limitations of the technology and of the broader system of care led some to trade off safety against immediate quality of life. Enhancing the quality and safety of the patient experience in HHD involves designing technology and the broader system of care to take account of how individuals manage their dialysis in the home. Possible design improvements to enhance the quality and safety of the patient experience include features to help patients manage their dialysis (e.g. providing timely reminders of next steps) and features to support communication between families and professionals (e.g. through remote monitoring).

    Trichinella larvae were detected in a marten (Martes martes) and a badger (Meles meles) in Poland. The animals were found dead following car accidents. All examined animals derived from the Mazurian Lake district, north-east Poland, near the village Kosewo Górne where Trichinella infection were earlier confirmed in wildlife; red foxes and wild boars. The muscle samples were examined by artificial pepsin-HCl digestion method. The parasites were identified as Trichinella britovi by multiplex polymerase chain reaction method. Larvae were found in two out of three martens and one out of seven examined badgers. This is the first report of the identification of Trichinella britovi larvae from martens and badgers in Poland.

    Parasites of the genus Trichinella are cosmopolitan nematodes infecting primarily wild animals, which represent the main reservoirs of these zoonotic pathogens. To investigate the transmission patterns of Trichinella spp. from wild to domestic animals and to humans and for the risk assessment of these parasites in a geographical area, it is important to know the number of possible transmission events deriving from carcasses of infected hosts. For this purpose, the evaluation of the larval biomass in reservoir hosts is needed. No data is available on how to estimate the biomass of Trichinella spp. larvae in muscles of naturally infected animals. The aim of this study was to evaluate the larval biomass in naturally infected pine martens (Martes martes) of Latvia, in which the prevalence of Trichinella britovi infection was over 50%. Single muscles or group of muscles (abdomen, back, diaphragm, intercostal muscles, muscles from the head, left and right shoulders, lower and upper parts of the forelimbs and hind limbs, neck, rump with tail, and base and tip of the tongue) were collected from five skinned and eviscerated carcasses of T. britovi infected pine martens. Muscles were entirely removed from the bones and weighted. Each muscle or group of muscles was separately digested to detect the larvae per gram (LPG). Using linear regression, the larval burden in each muscle or group of muscles was evaluated to measure the possible prediction of the total animal larval burden (both as total number of larvae and as average LPG). All muscles were significantly predictive of the total burden with high "goodness of fit" (all adjusted R2>0.80; P≤0.01), and the left shoulder provided the highest adjusted R2 (0.999). Then, to estimate the Trichinella britovi biomass in the pine marten population of Latvia, recent literature data on prevalence (56.2%, 95% CI: 47.8-64.3) and geometric mean LPG (1.26, 95% CI: 0.89-1.79) in the limb muscles of a sample representative of the whole

  8. The Relationship Between Digital Technology Experience, Daily Media Exposure and Working Memory Capacity

    Full Text Available Today’s youngsters interact with digital technologies to a great extent which leads scholars to question the influence of this exposure on human cognitive structure. Through resorting to digital nativity assumptions, it is presumed that cognitive architecture of the youth may change in accordance with digital technology use. In this regard, the current study investigated the relationship between digital technology experience, daily media exposure and working memory capacity of so-called digital native participants. A total of 572 undergraduate students responded to self-report measures, which addressed years of experience for 7 different digital devices and the daily time spent for 14 different digital activities. Participants’ working memory capacity was measured through the Computation Span and the Dot Matrix Test. While the former was used to measure the phonological loop capacity, the latter was used to address the visuo-spatial sketchpad capacity. Correlational analyses revealed that neither the phonological loop capacity nor the visuo-spatial sketchpad capacity was related to digital technology experience and daily media exposure. Thus, the transformative contribution of digital technology experience to human cognitive architecture could not be observed through the current measures

    Structured data storage technologies evolve very rapidly in the IT world. LHC experiments, and ATLAS in particular, try to select and use these technologies balancing the performance for a given set of use cases with the availability, ease of use and of getting support, and stability of the product. We definitely and definitively moved from the “one fits all” (or “all has to fit into one”) paradigm to choosing the best solution for each group of data and for the applications that use these data. This talk describes the solutions in use, or under study, for the ATLAS experiment and their selection process and performance.

    Bennison, Anne; Goos, Merrilyn

    2010-04-01

    The potential for digital technologies to enhance students' mathematics learning is widely recognised, and use of computers and graphics calculators is now encouraged or required by secondary school mathematics curriculum documents throughout Australia. However, previous research indicates that effective integration of technology into classroom practice remains patchy, with factors such as teacher knowledge, confidence, experience and beliefs, access to resources, and participation in professional development influencing uptake and implementation. This paper reports on a large-scale survey of technology-related professional development experiences and needs of Queensland secondary mathematics teachers. Teachers who had participated in professional development were found to be more confident in using technology and more convinced of its benefits in supporting students' learning of mathematics. Experienced, specialist mathematics teachers in large metropolitan schools were more likely than others to have attended technology-related professional development, with lack of time and limited access to resources acting as hindrances to many. Teachers expressed a clear preference for professional development that helps them meaningfully integrate technology into lessons to improve student learning of specific mathematical topics. These findings have implications for the design and delivery of professional development that improves teachers' knowledge, understanding, and skills in a diverse range of contexts.

  3. Moral responsibility, technology, and experiences of the tragic: from Kierkegaard to offshore engineering.

    Science.gov (United States)

    Coeckelbergh, Mark

    2012-03-01

    The standard response to engineering disasters like the Deepwater Horizon case is to ascribe full moral responsibility to individuals and to collectives treated as individuals. However, this approach is inappropriate since concrete action and experience in engineering contexts seldom meets the criteria of our traditional moral theories. Technological action is often distributed rather than individual or collective, we lack full control of the technology and its consequences, and we lack knowledge and are uncertain about these consequences. In this paper, I analyse these problems by employing Kierkegaardian notions of tragedy and moral responsibility in order to account for experiences of the tragic in technological action. I argue that ascription of responsibility in engineering contexts should be sensitive to personal experiences of lack of control, uncertainty, role conflicts, social dependence, and tragic choice. I conclude that this does not justify evading individual and corporate responsibility, but inspires practices of responsibility ascription that are less 'harsh' on those directly involved in technological action, that listen to their personal experiences, and that encourage them to gain more knowledge about what they are doing.

    and discuss our experiences from an ongoing deployment of a suite of context-aware technologies and applications in a hospital environment, including a context-awareness infrastructure, a location tracking system, and two context-aware applications running on interactive wall displays and mobile phones. Based...... on an analysis of the use of these systems, we observe that many of the ideas behind context-aware computing are valid, and that the context-aware applications are useful for clinicians in their work. By reflecting on the nature of the designed context-aware technologies, we present a model which states......Context-aware computing is a central concept in ubiquitous computing and many suggestions for context-aware technologies and applications have been proposed. There is, however, little evidence on how these concepts and technologies play out in a real-world setting. In this paper we describe...

  17. Literatura y realidad histórica. Un reencuentro con Ezequiel Martínez Estrada y su interpretación del Martín Fierro

    2010-01-01

    Full Text Available The purpose of this paper is to critically review some of the main theoretical tenets in Ezequiel Martínez Estrada’s pessimistic stance about the Argentinean history and society of his time. Focusing on his critical remarks about the so-called «literatura o poesía gauchesca» as well as on his enthusiastic assessment of José Hernández’ Martín Fierro, the achievements and missing points in Martínez Estrada’s skeptical diagnosis will be underlined and put in broader philosophical context. For the Argentinean writer the controversial notion of a “superimposed reality” – as he infers its existence from the Martín Fierro – captures a kind of ambivalent metaphysical concurrence among the literary creation, the geographical setting and the sociopolitical state of the country.

    Six species of nongastrointestinal nematodes were recovered from 405 marten, (Martes americana), examined from six areas in Ontario, Canada in 1992 to 1993. Three species (Crenosoma petrowi, Eucoleus aerophilus, Filaroides martis) were found in the respiratory tract, one in the urinary bladder (Pearsonema plica), one in the kidney (Dioctophyme renale), and one in the musculature (Trichinella sp. larvae). This is the first report of F. martis and P. plica from this host. In addition a specimen of Dracunculus insignis collected from a marten pelt was received. Based on our results, martens are primary definitive hosts for few nongastrointestinal nematodes. Animals in more southern areas had greater species richness than those from higher latitudes.

    Education in hydrology is changing rapidly due to diversification of students, emergent major scientific and practical challenges that our discipline must engage with, shifting pedagogic ideas and higher education environments, the need for students to develop new discipline specific and transferrable skills, and the advent of innovative technologies for learning and teaching. This paper focuses on new technologies in the context of learning and teaching in Physical Geography and reflects on the implications of our experiences for education in hydrology. We evaluate the experience of designing and trialling novel mobile technology-based field exercises and a virtual field tour for a Year 1 undergraduate Physical Geography module at a UK university. The new exercises are based on using and obtaining spatial data, operation of meteorological equipment (explained using an interactive DVD), and include introductions to global positioning systems (GPS) and geographical information systems (GIS). The technology and exercises were well received in a pilot study and subsequent rolling-out to the full student cohort (∼150 students). A statistically significant improvement in marks was observed following the redesign. Although the students enjoyed using mobile technology, the increased interactivity and opportunity for peer learning were considered to be the primary benefits by students. This is reinforced further by student preference for the new interactive virtual field tour over the previous "show-and-tell" field exercise. Despite the new exercises having many advantages, exercise development was not trivial due to the high start-up costs, the need for provision of sufficient technical support and the relative difficulty of making year-to-year changes (to the virtual field tour in particular). Our experiences are highly relevant to the implementation of novel learning and teaching technologies in hydrology education.

    Priest, Susanna Hornig; Greenhalgh, Ted

    2011-04-01

    This article analyzes nanotechnology as an experiment in democratic deliberation, one that seems motivated both by a desire to improve deliberative democracy and to protect the technology from undue public interference. However, rather than involving amplified (overstated) risks, nanotechnology appears to involve attenuated (understated) risks. Results from a 3-year panel study are presented to illustrate the ways in which citizens form opinions about nanotechnology, supporting the assertion that public opinion about complex technology can be both reasonable and stable. Nevertheless, the authors also voice concern that, in the absence of public pressure, risk regulation may not evolve as swiftly as it should to protect both society and industry.

    Assistive technology for computer access can be used to facilitate people with a spinal cord injury to utilize mainstream computer applications, thereby enabling participation in a variety of meaningful occupations. The aim of this study was to gain an understanding of the experiences of clients with tetraplegia trialing assistive technologies for computer access during different stages in a public rehabilitation service. In order to explore the experiences of clients with tetraplegia trialing assistive technologies for computer use, qualitative methodology was selected. Data were collected from seven participants using semi-structured interviews, which were audio-taped, transcribed and analyzed thematically. Three main themes were identified. These were: getting back into life, assisting in adjusting to injury and learning new skills. The findings from this study demonstrated that people with tetraplegia can be assisted to return to previous life roles or engage in new roles, through developing skills in the use of assistive technology for computer access. Being able to use computers for meaningful activities contributed to the participants gaining an enhanced sense of self-efficacy, and thereby quality of life. Implications for Rehabilitation Findings from this pilot study indicate that people with tetraplegia can be assisted to return to previous life roles, and develop new roles that have meaning to them through the use of assistive technologies for computer use. Being able to use the internet to socialize, and complete daily tasks, contributed to the participants gaining a sense of control over their lives. Early introduction to assistive technology is important to ensure sufficient time for newly injured people to feel comfortable enough with the assistive technology to use the computers productively by the time of discharge. Further research into this important and expanding area is indicated.

    Full Text Available The Cuban poet José Martí, “Master of the Americas” as pointed out by a famous Italian study by Carlo Batà, was probably the most important South American thinker of the two last decades of the Nineteenth century. This essay deals with the importance of “civilization clash” between US positivism - or WASP-ism - and the last resistances of Native Americans' cultural heritage during his personal experience as an exile in the United States. Martí, in this racial struggle and racist instincts, experienced a dual vision about the “Indian problem” in the Americas. In his first essays he focused on the positivistic view, really common among Latin American cultural élites (from Alberdi to Sarmiento, which depicted the Indian people as the burden of creole and white race in the path toward progress.On the other hand, as appeared clearly in Escenas americanas, the Cuban analysed more precisely the American struggle between civilization and savagery. In the cultural massacre inflicted to Indian tribes, he saw the real savagery in American civilization. So, this reflection paved the way to a new approach in considering the possibility of importing the Anglo-saxon model of civilization and political structures to the liberated Cuba after the independence (but also to continental Latin America.This relationship let us understand some interesting features in Martí's huge cultural production. We are introduced to the very essence of his cultural mediation between those two different lifestyles and models of civilization. This mediation would have represented a new way of intending North vs South America struggles or even Western way of life vs different ones, considered “barbarous” from the first.In our modern times, in which the terms “exporting values” or “civilization clash” seem to be very common in usage, it is really stimulating discover that the same problem was posed by Martí more than one century ago.

    2007-01-01

    Adoption of information technology in nursing practice has become a trend in healthcare. The impact of this technology on users has been widely studied, but little attention has been given to its influence at the beginning stage of implementation. Knowing the barriers to adopting technology could shorten this transition stage and minimize its negative influences. The purpose of this study was to explore nurses' experiences in the early stage of implementing a nursing information system. Focus groups were used to collect data at a medical center in Taiwan. The results showed that nurses had problems with the system's content design, had insufficient training, were concerned about data security, were stressed by added work, and experienced poor interdisciplinary cooperation. To smooth this beginning stage, the author recommends involving nurses early in the system design, providing sufficient training in keyboard entry skills, redesigning workflow, and improving interdisciplinary communication.

    2008-07-01

    INTRODUCTIONThe primary goal of the International Haplotype Map Project has been to develop a haplotype map of the human genome that describes the common patterns of genetic variation, in order to accelerate the search for the genetic causes of human disease. Within the project, ~3.9 million distinct single-nucleotide polymorphisms (SNPs) have been genotyped in 270 individuals from four worldwide populations. The project data are available for unrestricted public use at the HapMap Web site. This site, which is the primary portal to genotype data produced by the project, offers bulk downloads of the data set, as well as interactive data browsing and analysis tools that are not available elsewhere. Because of performance considerations, interactive access to HapMap data via the genome browser on the HapMap Web site is limited to regions no more than 5 Mb wide. Researchers who wish to obtain data for chromosome- or genome-wide data have two choices: Bulk download or HapMart access.

    2015-11-01

    Full Text Available Nuestro José Martí, ejemplo de una formación humanística integral, escribió en una carta a María Mantilla:”Donde yo encuentro poesía mayor es en los libros de ciencia…” Martí vio la ciencia como un fenómeno social y consideró que el desarrollo científico técnico debía estar en función de la satisfacción de las necesidades de las grandes mayorías. Su sistemática voluntad  de cultivarse, de tratar de entender al mundo y no sólo de vivirlo, de razonarlo, fue el motor principal que llevaría a Martí a hacerse de una cultura científica y técnica poco común entre los hombres de su época. También el hecho de vivir durante muchos años en los Estados Unidos le permitió analizar con  profundidad y realismo la sociedad de la época, y por tanto llegó a tener una visión muy avanzada de la relación hombre – naturaleza - sociedad, llegando a convertirse en un gran divulgador de los avances de la ciencia y la técnica de aquella época. La originalidad del periodismo de nuevo tipo que inicia José Martí como vehículo para la divulgación científico - técnica encuentra una de sus más altas expresiones en la revista “La América”. Esta publicación había comenzado en abril de 1882, en Nueva York, bajo la dirección de Rafael de Castro Palomino, quien solicita la colaboración del poeta. A partir del mes de marzo de 1883, el Maestro redacta “La América” en su totalidad, desde los titulares hasta los artículos ensayísticos. Martí caracteriza “La América” como “periódico útil”, pues se dedicó a divulgar los adelantos de la industria, comercio y agricultura de los productores de la América del Norte, y en el avisador prudente de los compradores de la América del Sur. Este carácter de la publicación permite a José Martí tratar desde las páginas de “La América” los recientes descubrimientos científicos, la reseña detallada de las exposiciones que exhibían los últimos logros de la t

    Full Text Available Kielmeyera coriacea Mart., known as “pau-santo”, is mentioned in the literature as the main tree species which produces cork of the Brazilian Cerrado. The purpose of this study was to describe the morphological aspect of Kielmeyera coriacea (“pau-santo” cork cells through its microscopic structure and to compare it with the cellular morphology of Quercus suber (cork oak, which is the main cork producing species worldwide. The bark from three trees of the species Kielmeyera coriacea Mart. was collected randomly at points 1.30 m above the ground, with four repetitions per sample. Samples came from native stands situated in the region of Luminárias - MG, Brazil. The study of morphological characteristics was conducted by counting the number of sides of the cells, and measuring the dimensions of the cells from images obtained by scanning electron microscopy (SEM. Images were analyzed using the LEOUIF software. The distribution in faces and edges of cork cells from Kielmeyera coriacea, was observed to have from 4 to 8 sides, with a predominance of hexagonal cells, similar to Quercus suber. The averages of height and thickness of the cell walls were 40 to 70 µm and 1.5 to 2.0 µm respectively, indicating cells from an early growth season. Both height and thickness were observed to be greater than those present in Quercus suber

    Full Text Available Regarding breast cancer treatment, triple negative breast cancer (TNBC is a difficult issue. Most TNBC patients die of cancer metastasis. Thus, to develop a new regimen to attenuate TNBC metastatic potential is urgently needed. MART-10 (19-nor-2α-(3-hydroxypropyl-1α,25(OH2D3, the newly-synthesized 1α,25(OH2D3 analog, has been shown to be much more potent in cancer growth inhibition than 1α,25(OH2D3 and be active in vivo without inducing obvious side effect. In this study, we demonstrated that both 1α,25(OH2D3 and MART-10 could effectively repress TNBC cells migration and invasion with MART-10 more effective. MART-10 and 1α,25(OH2D3 induced cadherin switching (upregulation of E-cadherin and downregulation of N-cadherin and downregulated P-cadherin expression in MDA-MB-231 cells. The EMT(epithelial mesenchymal transition process in MDA-MB-231 cells was repressed by MART-10 through inhibiting Zeb1, Zeb2, Slug, and Twist expression. LCN2, one kind of breast cancer metastasis stimulator, was also found for the first time to be repressed by 1α,25(OH2D3 and MART-10 in breast cancer cells. Matrix metalloproteinase-9 (MMP-9 activity was also downregulated by MART-10. Furthermore, F-actin synthesis in MDA-MB-231 cells was attenuated as exposure to 1α,25(OH2D3 and MART-10. Based on our result, we conclude that MART-10 could effectively inhibit TNBC cells metastatic potential and deserves further investigation as a new regimen to treat TNBC.

    Vadali, Srinivas R.; Carter, Michael T.

    1994-01-01

    The Phillips Laboratory at the Edwards Air Force Base has developed the Advanced Space Structures Technology Research Experiment (ASTREX) facility to serve as a testbed for demonstrating the applicability of proven theories to the challenges of spacecraft maneuvers and structural control. This report describes the work performed on the ASTREX test article by Texas A&M University under contract NAS119373 as a part of the Control-Structure Interaction (CSI) Guest Investigator Program. The focus of this work is on maneuvering the ASTREX test article with compressed air thrusters that can be throttled, while attenuating structural excitation. The theoretical foundation for designing the near minimum-time thrust commands is based on the generation of smooth, parameterized optimal open-loop control profiles, and the determination of control laws for final position regulation and tracking using Lyapunov stability theory. Details of the theory, mathematical modeling, model updating, and compensation for the presence of 'real world' effects are described and the experimental results are presented. The results show an excellent match between theory and experiments.

    Attalea phalerata Mart. ex Spreng., popularly known as "bacuri", is a native plant from the brazilian Cerrado and used in folk medicine as a pulmonary decongestant, an anti-inflammatory for joints and antipyretic. There is an expectation about the use in chronic disease of the Attalea phalerata oil since its composition is high in carotenoids and beneficial fatty acids. The aim of the study was to evaluate the toxicological profile of the oil extracted from Attalea phalerata Mart. ex Spreng. pulp (APO). Acute and subacute toxicity studies were performed in male and female Wistar rats according to the OECD - Guidelines 425 and 407. For the acute toxicity, one single dose of the APO (2000mg/kg) was administered by gavage to five female rats. In the subacute toxicity, four different doses (125, 250, 500 and 1000mg/kg) of the APO were administered to male and female rats for 28 consecutive days. No deaths or behavioral changes were observed during both experiments as well as no changes in organ weights, hematological, histopathological parameters. The biochemical parameters showed changes in phosphatase alkaline and albumin levels, however these values are within the normal range for the species. A significant reduction in cholesterol and triglycerides was also observed in some of the animals treated with the APO. Therefore, the LD50 is higher than 2000mg/kg and the APO oil can be considered safe at the doses tested in rats. However, further assessments are required in order to proceed to clinical studies in humans.

    Authentic research opportunities in the classroom are most impactful when they are student-driven and inquiry-based. These experiences are even more powerful when they involve technology and meaningful connections with scientists. In today's classrooms, activities are driven by state required skills, education standards, and state mandated testing. Therefore, programs that incorporate authentic research must address the needs of teachers. NASA's Expedition Earth and Beyond (EEAB) Program has developed a framework that addresses teacher needs and incorporates the use of technology and access to mentors to promote and enhance authentic research in the classroom. EEAB is a student involvement program that facilitates student investigations of Earth or planetary comparisons using NASA data. To promote student-led research, EEAB provides standards-aligned, inquiry-based curricular resources, an implementation structure to facilitate research, educator professional development, and ongoing support. This framework also provides teachers with the option to incorporate the use of technology and connect students with a mentor, both of which can enrich student research experiences. The framework is structured by a modeled 9-step process of science which helps students organize their research. With more schools gaining increased access to technology, EEAB has created an option to help schools take advantage of students' interest and comfort with technology by leveraging the use of available technologies to enhance student research. The use of technology not only allows students to collaborate and share their research, it also provides a mechanism for them to work with a mentor. This framework was tested during the 2010/2011 school year. Team workspaces hosted on Wikispaces for Educators allow students to initiate their research and refine their research question initially without external input. This allows teams to work independently and rely on the skills and interests of

    This study examines the role of video technology in the development of cooking skills. The study explored the views of 141 female participants on whether video technology can promote confidence in learning new cooking skills to assist in meal preparation. Prior to each focus group participants took part in a cooking experiment to assess the most effective method of learning for low-skilled cooks across four experimental conditions (recipe card only; recipe card plus video demonstration; recipe card plus video demonstration conducted in segmented stages; and recipe card plus video demonstration whereby participants freely accessed video demonstrations as and when needed). Focus group findings revealed that video technology was perceived to assist learning in the cooking process in the following ways: (1) improved comprehension of the cooking process; (2) real-time reassurance in the cooking process; (3) assisting the acquisition of new cooking skills; and (4) enhancing the enjoyment of the cooking process. These findings display the potential for video technology to promote motivation and confidence as well as enhancing cooking skills among low-skilled individuals wishing to cook from scratch using fresh ingredients.

    Gorev, Dvora; Gurevich-Leibman, Irina

    2015-07-01

    This paper presents our experience of integrating technological tools into our mathematics teaching (in both disciplinary and didactic courses) for student-teachers. In the first cycle of our study, a variety of technological tools were used (e.g., dynamic software, hypertexts, video and applets) in teaching two disciplinary mathematics courses. We found that the tool most preferred by the students was dynamic software, while the applets were almost neglected. In the next cycle, we focused on using various applets in both disciplinary and didactic mathematics courses. We found that if the assignments were applet-oriented, i.e., adjusted to the chosen applet, or vice versa - the applet was chosen appropriately to suit the given assignment - then the students were able to make use of applets in an effective way. Furthermore, the students came to see the potential of applets for improving learning.

  15. Programming Massively Parallel Architectures using MARTE: a Case Study

    CERN Document Server

    Rodrigues, Wendell; Dekeyser, Jean-Luc

    2011-01-01

    Nowadays, several industrial applications are being ported to parallel architectures. These applications take advantage of the potential parallelism provided by multiple core processors. Many-core processors, especially the GPUs(Graphics Processing Unit), have led the race of floating-point performance since 2003. While the performance improvement of general- purpose microprocessors has slowed significantly, the GPUs have continued to improve relentlessly. As of 2009, the ratio between many-core GPUs and multicore CPUs for peak floating-point calculation throughput is about 10 times. However, as parallel programming requires a non-trivial distribution of tasks and data, developers find it hard to implement their applications effectively. Aiming to improve the use of many-core processors, this work presents an case-study using UML and MARTE profile to specify and generate OpenCL code for intensive signal processing applications.

  16. eSciMart: Web Platform for Scientific Software Marketplace

    Science.gov (United States)

    Kryukov, A. P.; Demichev, A. P.

    2016-10-01

    In this paper we suggest a design of a web marketplace where users of scientific application software and databases, presented in the form of web services, as well as their providers will have presence simultaneously. The model, which will be the basis for the web marketplace is close to the customer-to-customer (C2C) model, which has been successfully used, for example, on the auction sites such as eBay (ebay.com). Unlike the classical model of C2C the suggested marketplace focuses on application software in the form of web services, and standardization of API through which application software will be integrated into the web marketplace. A prototype of such a platform, entitled eSciMart, is currently being developed at SINP MSU.

    Important technical issues must be resolved before co-pyrolysis and co-gasification technologies can be offered as commercially viable processes. Clearly, issues such as solids handling and solids injection require solutions developed at actual plant or pilot scale. However, research on numerous other residual problems can be carried out effectively, rapidly, and inexpensively at bench-scale level. This article describes several cases where problems encountered during pilot or plant scale operation can be studied by experiments at bench-top levels; the designs of the bench-scale reactors used in these studies are presented and discussed. 34 refs., 6 figs., 2 tabs.

    2016-03-01

    Full Text Available The necessity to form and develop future technology teachers’ creative abilities has been stressed in the article. The psychologic-pedagogical researches of the leading specialists from Europe, the USA and Japan in the field of creative work and creativity have been analyzed. The main problems of the creative artistic-projective abilities development have been determined based on the analysis and synthesis of foreign and native philosophic, pedagogical and psychological literature dedicated to characteristics of such notions as “creative work” and “creativity”. Approaches and conceptions providing students – future technology teachers – with creative activities have been singled out. The gist of psychological mechanism for forming teachers’ creative personality has been established and its basic features have been determined as a result of the world experience of the theory and methods of creative abilities development generalization. The main features are as follows: an independence and an inclination towards divergent behavior; flexibility of thinking and readiness for everything new; motivation for self-actualization; striving for self-expressing and ability to creative work; ability to find out how to set and solve the problems. It has been mentioned that the technology teachers’ artistic-projective activity requires their creative abilities development, which, in their turn, are formed on the ground of well-developed general and special (art, projective, technological, pedagogical potencies. Therefore, the effectiveness of the students’ art-projective knowledge and skills forming depends upon the extent their general, special and creative abilities have been developed. That is why skillful and pedagogically correct organization of future technology teachers’ artistic-projective activities will inevitably provide the higher qualitatively new level of their creative abilities and creativity.

    Júnior, Joel Quintino de Oliveira; Jesus, Ederson da Conceição; Lisboa, Francy Junio; Berbara, Ricardo Luis Louro; Faria, Sergio Miana de

    The family Leguminosae comprises approximately 20,000 species that mostly form symbioses with arbuscular mycorrhizal fungi (AMF) and nitrogen-fixing bacteria (NFB). This study is aimed at investigating and confirming the dependence on nodulation and biological nitrogen fixation in the specie Piptadenia gonoacantha (Mart.) Macbr., which belongs to the Piptadenia group. Two consecutive experiments were performed in a greenhouse. The experiments were fully randomized with six replicates and a factorial scheme. For the treatments, the two AMF species and three NFB strains were combined to nodulate P. gonoacantha in addition to the control treatments. The results indicate this species' capacity for nodulation without the AMF; however, the AMF+NFB combinations yielded a considerable gain in P. gonoacantha shoot weight compared with the treatments that only included inoculating with bacteria or AMF. The results also confirm that the treatment effects among the AMF+NFB combinations produced different shoot dry weight/root dry weight ratios. We conclude that AMF is not necessary for nodulation and that this dependence improves species development because plant growth increases upon co-inoculation.

  10. The Almohad Mecca. Locating Igli and the Cave of Ibn Tūmart

    Directory of Open Access Journals (Sweden)

    Fromherz, Allen J.

    2005-06-01

    Full Text Available Igli was the Mecca of the Almohads. In the Cave of Igli Muḥammad Ibn Tūmart proclaimed the beginning of the Almohad movement in North Africa. Despite the obvious importance of Igli, there was little knowledge about the precise location of Igli or the famous cave of Ibn Tūmart on the map. This paper details the discovery of the small village of Igli 30 kilometers East of Tarūdant. The location of this modem village corresponds with Almohad Igli. Primary sources, oral testimony and physical remains are all evidence that modem Igli was the birthplace of Ibn Tūmart.

    Igli era La Meca de los Almohades. En la cueva de Igli Muḥammad Ibn Tūmart proclamó el principio del movimiento almohade en África del norte. A pesar de la importancia de Igli, no se conocía su localización exacta o de la cueva de Ibn Tūmart. Aquí se detalla el descubrimiento de la pequeña aldea de Igli 30 kilómetros al este de Tarūdant. La localización de esta aldea moderna parece corresponder con el Igli almohade. Las fuentes primarias, el testimonio oral y los restos físicos se aducen como evidencia de que el Igli moderno era el lugar de nacimiento de Ibn Tūmart.

  12. Facing global markets – usage changes in Western Amazonian plants: the example of Euterpe precatoria Mart. and E. oleracea Mart.

    Directory of Open Access Journals (Sweden)

    Rainer W. Bussmann

    2012-11-01

    Full Text Available Palms (Arecaceae are one of the most important families of useful plants, and indigenous societies have developed very distinct ways of utilizing this resource. The clonal Euterpe oleracea Mart. has long been used for the preparation of frothy beverages in the eastern Amazon, in particular by colonists and caboclos, but to a much lesser extent by the indigenous population. Euterpe precatoria Mart., which grows in the western Amazon, is traditionally reported as resource for construction and thatch, but not as important species in alimentation. Our recent work indicates that the use of both species has dramatically shifted in the recent past. Prices for Euterpe products have increased dramatically due to the global commodization first of palm hearts and “Açaí berry juice” as nutritional supplement. This is especially evident in western Amazonia: In Bolivia and Peru, where older indigenous informants mostly reported thatch and houseposts as regular use for E. precatoria and did not know E. oleracea. Younger informants most commonly reported to a large extent on E. precatoria being used for the production of palm hearts, but less for other, while the youngest informants in many cases only knew E. precatoria fruits as source of beverages, as commercial fruit, and as source for handicrafts, and indicated that E. oleracea was being introduced because the species yielded higher harvests. In addition, many mid-age and younger informants reported Euterpe sp. as medicinal species, a less frequently mentioned by older informants. The local mestizo population in contrast had a broader distributed knowledge with regard to “food” uses of Euterpe sp., and mentioned the species as source of construction material less frequently.

    2015-09-01

    Recent discussions have focused on using health information technology (HIT) to support goals related to universal healthcare delivery. These discussions have generally not reflected on the experience of countries with a large amount of experience using HIT to support universal healthcare on a national level. HIT was compared globally by using data from the Ministry of the Interior, Republic of China (Taiwan). Taiwan has been providing universal healthcare since 1995 and began to strategically implement HIT on a national level at that time. Today the national-level HIT system is more extensive in Taiwan than in many other countries and is used to aid administration, clinical care, and public health. The experience of Taiwan thus can provide an illustration of how HIT can be used to support universal healthcare delivery. In this article we present an overview of some key historical developments and successes in the adoption of HIT in Taiwan over a 17-year period, as well as some more recent developments. We use this experience to offer some strategic perspectives on how it can aid in the adoption of large-scale HIT systems and on how HIT can be used to support universal healthcare delivery.

  15. Higher education staff experiences of using web-based learning technologies

    2004-01-01

    Full Text Available Given the drive in higher education institutions to employ web-based learning (WBL technologies in their curricula, this article sets out to address the question of how staff experience the incorporation of such technologies into their educational practice. The study focuses on an initiative involving four institutions in South and West England that aimed to encourage the strategic development of WBL resources in health and welfare professional education programmes. Thirty-three higher educational staff from a range of organisational locations took part in a qualitative process study. The findings suggest that while staff were enthusiastic about their engagement with WBL they experienced problems embedding their project work within their organisations, managing their time and obtaining institutional recognition for their work. Such findings represent a challenge to commentaries that emphasise “technological illiteracy” or “technophobia” amongst staff as barriers to WBL implementation. The study favours an analysis that emphasises how WBL initiatives are incorporated into existing higher education managerial, decision-making and reward structures.

    2014-02-01

    The US health care system has been slow to adopt Internet, mobile, and video technologies, which have the capability to engage patients in their own care, increase patients' access to providers, and possibly improve the quality of care while reducing costs. Nevertheless, there are some pockets of progress, including Kaiser Permanente Northern California (KPNC). In 2008 KPNC implemented an inpatient and ambulatory care electronic health record system for its 3.4 million members and developed a suite of patient-friendly Internet, mobile, and video tools. KPNC has achieved many successes. For example, the number of virtual "visits" grew from 4.1 million in 2008 to an estimated 10.5 million in 2013. This article describes KPNC's experience with Internet, mobile, and video technologies and the obstacles faced by other health care providers interested in embracing them. The obstacles include the predominant fee-for-service payment model, which does not reimburse for virtual visits; the considerable investment needed to deploy these technologies; and physician buy-in.

    Gazey, R.; Salman, S. K.; Aklil-D'Halluin, D. D.

    This paper aims to share the field application experience related to the development of an innovative stand-alone sustainable energy system known as the PURE project. The PURE project has been developed alongside a Knowledge Transfer Partnership (KTP) scheme, which is supported by the UK Department of Trade and Industry and executed by siGEN in collaboration with The Robert Gordon University. The system has been constructed within an industrial estate on the island of Unst in Shetland, 200 miles north of the Scottish mainland. The energy system now supplies five business properties with clean reliable power and utilises wind turbine and hydrogen technology to provide a sustainable energy source. The stored hydrogen gas generated by the system is used as an energy source for periods when electrical demand within the business properties exceeds wind turbine production. The hydrogen is also utilised as a fuel source for transportation and as a transportable energy source for mobile power generation. The paper therefore gives a detailed description of the PURE project and discusses the field experience accumulated during the development and installation of the system. It also shares a number of practical issues that had to be overcome during its integration and operation. The installation of the PURE project has resulted in a number of unexpected conclusions being identified and marks a significant step forward in the accessible deployment of this technology for community use.

Discussions between researchers and participants about the materials collected (and sometimes about what had prevented them completing the tasks helped elicit further information relevant to assisted living technology design. The probe materials were particularly helpful when having conversations with non-English speaking participants through an interpreter. Conclusions Cultural probe methods can help build a rich picture of the lives and experiences of older people to facilitate the co-production of assisted living technologies. But their application may be constrained by the participant’s physical, mental and emotional capacity. They are most effective when used as a tool to facilitate communication and development of a deeper understanding of older people’s needs.

    There is an increasing interest in reaching consumers directly through the Internet and different telecommunication systems. The most important contacts in health care will always be the face-to-face meetings, but the tools of health informatics can be seen as a means to an end, which is to provide the best possible health care. A variety of applications have been described in different references. To our knowledge there has been no review of a research-based state of the art in the field of consumers' experiences in using different applications in health informatics. According to the benefits in using information communication technology (ICT) as being cost-effective and timesaving it is of great importance to focus on and examine consumers' experiences. It is important that it is user friendly and regarded as valuable and useful. The aim of this study was to describe consumers' subjective experiences of using electronic resources with reference to health and illness. DESIGN AND/OR METHOD: A systematic literature search was performed in databases CINAHL, Medline and Cochrane, as well as a manual search. Retrieved references (n=14) were appraised according to their scientific structure and quality. A broad search was performed in order to find as many different applications as possible. Our primary intention was to identify existing references describing consumers' experiences with ICT. In spite of this broad search few references were found. Twelve references remained and three themes were identified: support and help, education and information, and telecommunication instead of on-site visiting. Consumers felt more confident and empowered, their knowledge increased and their health status improved due to the ICT resources. Lack of face-to-face meetings or privacy did not appear to be a problem. ICT can improve the nurse-patient relationship and augment well-being for consumers. More research is needed to measure consumers' experiences and factors that influence it

Out of the 186, 43 or 23% were working for banking and finance-related sector and 39 or 21% were in trading and merchandising. The study showed that most of the graduates were able to start a career path by gaining entry to prestigious companies. Five themes emerged from the 16 reflections: self confidence in performing assigned tasks, positive attitude, value of experience, traits developed in school and financial considerations. The themes that emerged reflected three core essences or factors that made them stay or contributory to their being retained by their employers on the job: financial or being able to buy what they want and help the family in the daily expenses; attitude, self-confidence and skills developed in school, as contributory to their work performance and retention; and experience, the main reason for staying on the job despite physical and emotional difficulties.

    Full Text Available Considering the potential and importance of biodiversity of the Caatinga biome, studies on endemic species are relevant to conservation of its natural resources. The objectives of this work was to evaluate seed viability and physical methods for overcoming seed dormancy in juazeiro (Ziziphus joazeiro Mart. and assess the influence of different types of soil on the initial growth of juazeiro plants. The experiments were conducted in three stages. In the first stage, the viability of seeds from different lots was evaluated using the tetrazolium test. The second stage was conducted in a plant nursery, evaluating the application of physical processes (scarification with sandpaper and hammer in overcoming seed dormancy, and the initial growth of the plants. In the third step, the chlorophyll a and b contents, gas exchange and dry matter accumulation were evaluated in young juazeiro plants in three types of soil (Oxisol, Entisol and Vertisol. The results indicate that the viability of juazeiro seeds is greatly influenced by differences between the progenitor plants and by storage conditions, which enable a longevity of two years when stored at 22°C and 16% of relative humidity. The scarification methods with sandpaper and hammer are not efficient to reduce the time and uniform seed germination. The juazeiro plants have high growth potential in different edaphic environments, adapting well to soils of different textures and chemical compositions.

    Full Text Available There is growing evidence on the importance of rehabilitation interventions promoting the persistence of the sense of self in people with Alzheimer's disease (AD or other forms of dementia. Assistive Technologies (AT may contribute to the development of interventions aimed to improve adaptive responses to environmental demands. This, in turns, can promote self-awareness. At the same time AT can manage computer interfaces able to record and reproduce autobiographical multimedia contents that can be very useful during reminiscence tasks carried out during conversations with supportive staff. These tasks could promote the self-concept. Globally the AT can be of great help in setting up rehabilitation and leisure environments promoting the experience of self in people with AD and other dementias.

    2006-09-01

    The aim of this exploratory study was to understand the negotiation of care as experienced by the parents of technology-dependent children in a hospital context. Qualitative semi-structured interviews were undertaken with a group of six parents. Parents felt that their roles as parents were not considered enough by nurses and they tended to be seen as carers, not parents. Negotiation of care was not always apparent. Instead, nurses often made assumptions about parental involvement in care. Parents wanted to carry out care when in hospital, but were not always given choices. Parents also reported a desire for more confident nurses. This study highlights the need to gain insight into parents' experiences, in order that nurses can provide care in a way negotiated to suit the individual family. Suggestions for further research in this area are offered.

    Technology has the potential to impact cognition in many ways. Here we contrast two forms of technology usage: 1) media multitasking (i.e., the simultaneous consumption of multiple streams of media, such a texting while watching TV) and 2) playing action video games (a particular sub-type of video game). Previous work has outlined an association between high levels of media multitasking and specific deficits in handling distracting information, while playing action video games has been associated with enhanced attentional control. As these two factors are linked with reasonably opposing effects, failing to take them jointly into account may result in inappropriate conclusions as to the impact of technology use on attention. Across four experiments (AX-CPT, N-back, Task-switching and Filter task), testing different aspects of attention and cognition, we show that heavy media multitaskers perform worse than light media multitaskers. Contrary to previous reports though, the performance deficit was not specifically tied to distractors, but was instead more global in nature. Interestingly, participants with intermediate levels of media multitasking occasionally performed better than both light and heavy media multitaskers suggesting that the effects of increasing media multitasking are not monotonic. Action video game players, as expected, outperformed non-video game players on all tasks. However, surprisingly this was true only for participants with intermediate levels of media multitasking, suggesting that playing action video games does not protect against the deleterious effect of heavy media multitasking. Taken together this study shows that media consumption can have complex and counter-intuitive effects on attentional control. PMID:26474982

    Identifying research priorities is key to innovation and economic growth, since it informs decision makers on effectively targeting issues that have the greatest potential public benefit. As such, the process of setting research priorities is of pivotal importance for favouring the science, technology, and innovation (STI)-driven development of low- and middle-income countries. We report herein on a major cross-sectoral nationwide research priority setting effort recently carried out in Tanzania by the Tanzania Commission for Science and Technology (COSTECH) in partnership with the Council on Health Research for Development (COHRED) and the NEPAD Agency. The first of its type in the country, the process brought together stakeholders from 42 sub-sectors in science, technology, and health. The cross-sectoral research priority setting process consisted of a 'training-of-trainers' workshop, a demonstration workshop, and seven priority setting workshops delivered to representatives from public and private research and development institutions, universities, non-governmental organizations, and other agencies affiliated to COSTECH. The workshops resulted in ranked listings of research priorities for each sub-sector, totalling approximately 800 priorities. This large number was significantly reduced by an expert panel in order to build a manageable instrument aligned to national development plans that could be used to guide research investments. The Tanzania experience is an instructive example of the challenges and issues to be faced in when attempting to identify research priority areas and setting an STI research agenda in low- and middle-income countries. As countries increase their investment in research, it is essential to increase investment in research management and governance as well, a key and much needed capacity for countries to make proper use of research investments.

    The Classic 25 is the product name for a motive-power lead/acid cell using thin positive tubular plates. This cell was developed for use in electric vehicles and other applications where high specific energy and reliable cycle life is required. It would appear that the best approach is to provide a lead/acid battery that has the highest specific energy while still maintaining excellent cycle life. This technology was implemented by use of 6 V modules, followed by a 2-V design. Since this was first introduced in 1989, more than 20 000 cells and monoblocs have been delivered to various electric vehicle applications such as vans, trucks, and buses. The field experience with this product is therefore excellent, and development is continuing on the battery design and manufacturing techniques to improve performance and life even further. Today, a wide range of products using this technology is available, and the latest developments are a new 6 V monobloc and some maintenance-free cells. (orig.)

    Luehea candicans Mart. et Zucc. (Tiliaceae) is known as 'açoita-cavalo' and is one of the most important medicinal plants found in the Brazilian cerrado. The crude methanolic extracts of the branches and leaves and their fractions were evaluated using the following cancer cell lines: MCF-7 (breast), NCI-ADR (breast expressing the multidrug resistance phenotype), NCI-460 (lung), UACC-62 (melanoma), 786-0 (kidney), OVCAR (ovarian), PCO-3 (prostate), HT-29 (colon) and K-562 (leukaemia). The crude methanolic extracts from the branches (B) and leaves (L) were able to inhibit the growth of the K-562 and 786-0 cell lines in a dose-dependent manner, with GI(50) values of 8.1 and 5.4 µg mL(-1), respectively. The hexane (L1), chloroform (L2) and methanol (L4) fractions derived from extract L showed a high selectivity and pronounced cytostatic activity against 786-0 (GI(50) ~ 40 µg mL(-1)). A significant amount of lupeol was isolated from fraction L2. The chloroform (B2) and methanol (B3) fractions derived from extract (B) exhibited less selectivity, showing the highest cytostatic activity against K-562, NCI-ADR, OVCAR, MCF-7 and NCI-460 cells, with GI(50) values between 27 and 40 µg mL(-1). Lupeol, betulin, a mixture of steroids, (-)-epicatechin, vitexin and liriodendrin were isolated from these active fractions.

    2015-01-01

    Abstract The use of midazolam as a tranquilizer for anesthesia in mustelids in conjunction with the cyclohexamine ketamine is not well documented. Because midazolam is fast acting, inexpensive, and quickly metabolized, it may serve as a good alternative to other more commonly used tranquilizers. We trapped and anesthetized 27 Pacific martens (Martes caurina) in Lassen National Forest (northern California, US) August 2010-April 2013. We assessed anesthesia with ketamine at 18 and 25 mg/kg combined with 0.2 mg/kg of midazolam by comparing mean times of induction, return to consciousness, and recovery, plus physiologic parameters. No reversal was used for the midazolam portion of the anesthetic. Mean (±SD) induction for both ketamine dosages was 1.7±0.5 and 1.8±1.0 min, respectively. Return to consciousness mean times were 8.0 min longer (Pmidazolam provided reliable field anesthesia for Pacific martens, and supplemental oxygen is recommended as needed.

    Full Text Available The objectives of this study was the physical, chemical, and physiological characterization of marolo (Annona crassiflora, Mart. during its development. The fruits were harvested 12 Km off Itumirim, Southern Minas Gerais, Brazil, at 20-d intervals from anthesis to fruit maturity. The first fruits were harvested within 60 days. The total development of the fruit took 140 days starting from anthesis. At 140 days after anthesis, the fruit reached its maximum size, with mass of 1.380g, transverse diameter of 13.0 cm, and longitudinal diameter of 11.5 cm. During its development, the fruit showed increase in mass and in traverse and longitudinal diameters. The changes during maturation and ripening, such as: pH reduction and starch degradation, pectic solubilization, and increase in total sugars, soluble solids (ºB, respiratory rate (CO2, titratable acidity, vitamin C, and β-caroteno were observed from the 120th day of marolo development. A decrease in ability to sequester free radicals was observed up the 120th day, followed by an increase. The volatile compounds identified at the end of the development included the esters group only.

    The present study investigated the antioxidant properties of Cyathea phalerata Mart. (Cyatheaceae) using in vitro and in vivo assays. The in vitro antioxidant potential of the crude extract (CE), precipitate (PPT), aqueous fraction (AQF), n-butanolic fraction (BUF) and ethyl acetate fraction (EAF) from C. phalerata was evaluated through the scavenging of diphenyl-1-picryl-hydrazyl-hydrate (DPPH), superoxide anion (O(2)(*-)) (nitroblue tetrazolium assay) and hydroxyl radicals (OH(*)) (deoxyribose assay), and lipid peroxidation in rat liver homogenate. In these assays, it was observed that EAF had marked antioxidant potential, especially as a scavenger of the OH(*) radical and in inhibiting lipid peroxidation. The in vivo evaluation of oxidative stress (DNA fragmentation, membrane lipoperoxidation and carbonyl protein formation) and the antioxidant defenses (concentration of reduced glutathione, as well as catalase and glutathione S-transferase activities) were measured in mice pre-treated with EAF (10, 30 or 100 mg/kg, orally) and later exposed to carbon tetrachloride (CCl(4)). The EAF decreased thiobarbituric acid reactive substances levels, DNA damage and carbonyl protein contents, and increased catalase and glutathione S-transferase activities. Based on these results, it is concluded that the EAF from C. phalerata protects liver from oxidative stress induced by CCl(4) in mice and these effects are probably related to the antioxidant activity associated with the free radical scavenging property of this fraction.

    Full Text Available The article deals with the study of foreign experience in training engineering educators for modeling technological processes. It has been stated that engineering education is a field that is being dramatically developed taking into account the occurring changes in educational paradigms, global higher education space, national higher education systems, economics, society, etc. It has been indicated that the abundance of the latest information and communication technologies alter the approaches to training various specialists, and, in particular, engineering educators. It has been mentioned that engineering teacher education is undergoing significant development. The activities of the International Society for Engineering Education – IGIP have been justified. It has been found out that there is the vital need for those specialists able to combine the techniques of traditional teaching and innovative scientific achievements, design technical structures, be leader and facilitator of the education process. It has been defined that the activity of the society is aimed at providing engineering educators with relevant training that involves their obtaining the qualification that is accorded with European education standards. US experience in training engineering educators for professional activity has been analyzed. It has been specified that engineering education has become more integrated into the curricula of elementary, middle and high school because of the increasing focus on STEM subjects; the demand for engineering educators is dramatically growing at all the levels of the education system. The peculiarities of engineering educators’ training have been demonstrated on the example of the Purdue Polytechnic Institute. It has been concluded that Bachelor of Science in Engineering Technology Teacher Education is a rather interdisciplinary degree program and trains future engineering educators for a wide range of fields.

  3. Reducing cognitive load in the chemistry laboratory by using technology-driven guided inquiry experiments

    Hubacz, Frank, Jr.

    The chemistry laboratory is an integral component of the learning experience for students enrolled in college-level general chemistry courses. Science education research has shown that guided inquiry investigations provide students with an optimum learning environment within the laboratory. These investigations reflect the basic tenets of constructivism by engaging students in a learning environment that allows them to experience what they learn and to then construct, in their own minds, a meaningful understanding of the ideas and concepts investigated. However, educational research also indicates that the physical plant of the laboratory environment combined with the procedural requirements of the investigation itself often produces a great demand upon a student's working memory. This demand, which is often superfluous to the chemical concept under investigation, creates a sensory overload or extraneous cognitive load within the working memory and becomes a significant obstacle to student learning. Extraneous cognitive load inhibits necessary schema formation within the learner's working memory thereby impeding the transfer of ideas to the learner's long-term memory. Cognitive Load Theory suggests that instructional material developed to reduce extraneous cognitive load leads to an improved learning environment for the student which better allows for schema formation. This study first compared the cognitive load demand, as measured by mental effort, experienced by 33 participants enrolled in a first-year general chemistry course in which the treatment group, using technology based investigations, and the non-treatment group, using traditional labware, investigated identical chemical concepts on five different exercises. Mental effort was measured via a mental effort survey, a statistical comparison of individual survey results to a procedural step count, and an analysis of fourteen post-treatment interviews. Next, a statistical analysis of achievement was

    Full Text Available In chemical plants, safety measures are needed in order to minimize the impact of severe accidents and natural disasters. At the same time, carrying out the education and training to workers the corresponding operation in non-stationary situation is essential. However, reproducing the non-stationary conditions to actual equipment or mock-up cannot be performed because it is dangerous. By using the virtual reality (VR technology, we can build up a virtual chemical plant with lower cost compared to real plant. The operator can experience the fire and explosion accidents in the virtual space. Therefore, in this paper, we propose an experienced-based safety training system for implementing the education and training by using the non-stationary situation in the computer. This proposed system is linked with the dynamic plant simulator. A trainee can learn the correct operation through the simulated experience to prevent an accident. The safety awareness of workers will improve by experiential learning. The proposed system is useful for safety education in chemical plant.

    The ASCENDS CarbonHawk Experiment Simulator (ACES) is a NASA Langley Research Center project funded by NASA's Earth Science Technology Office that seeks to advance technologies critical to measuring atmospheric column carbon dioxide (CO2) mixing ratios in support of the NASA Active Sensing of CO2 Emissions over Nights, Days, and Seasons (ASCENDS) mission. The technologies being advanced are: (1) multiple transmitter and telescope-aperture operations, (2) high-efficiency CO2 laser transmitters, (3) a high bandwidth detector and transimpedance amplifier (TIA), and (4) advanced algorithms for cloud and aerosol discrimination. The instrument architecture is being developed for ACES to operate on a high-altitude aircraft, and it will be directly scalable to meet the ASCENDS mission requirements. The above technologies are critical for developing an airborne simulator and spaceborne instrument with lower platform consumption of size, mass, and power, and with improved performance. This design employs several laser transmitters and telescope-apertures to demonstrate column CO2 retrievals with alignment of multiple laser beams in the far-field. ACES will transmit five laser beams: three from commercial lasers operating near 1.57-microns, and two from the Exelis atmospheric oxygen (O2) fiber laser amplifier system operating near 1.26-microns. The Master Oscillator Power Amplifier at 1.57-microns measures CO2 column concentrations using an Integrated-Path Differential Absorption (IPDA) lidar approach. O2 column amounts needed for calculating the CO2 mixing ratio will be retrieved using the Exelis laser system with a similar IPDA approach. The three aperture telescope design was built to meet the constraints of the Global Hawk high-altitude unmanned aerial vehicle (UAV). This assembly integrates fiber-coupled transmit collimators for all of the laser transmitters and fiber-coupled optical signals from the three telescopes to the aft optics and detector package. The detector

    Kolo, Yovonda Ingram

    African American women are underrepresented in science, technology, engineering, and mathematics (STEM) fields throughout the United States. As the need for STEM professionals in the United States increases, it is important to ensure that African American women are among those professionals making valuable contributions to society. The purpose of this phenomenological study was to describe the experiences of African American young women in relation to STEM education. The research question for this study examined how experiences with STEM in K-10 education influenced African American young women's academic choices in their final years in high school. The theory of multicontextuality was used to provide the conceptual framework. The primary data source was interviews. The sample was composed of 11 African American young women in their junior or senior year in high school. Data were analyzed through the process of open coding, categorizing, and identifying emerging themes. Ten themes emerged from the answers to research questions. The themes were (a) high teacher expectations, (b) participation in extra-curricular activities, (c) engagement in group-work, (d) learning from lectures, (e) strong parental involvement, (f) helping others, (g) self-efficacy, (h) gender empowerment, (i) race empowerment, and (j) strategic recruitment practices. This study may lead to positive social change by adding to the understanding of the experiences of African American young women in STEM. By doing so, these findings might motivate other African American young women to pursue advanced STEM classes. These findings may also provide guidance to parents and educators to help increase the number of African American women in STEM.

  7. New tools and technology for the study of human performance in simulator experiments

    2003-07-01

    This thesis suggests that new tools and technology can be used for production of relevant data and insights from the study of human performance in simulator and field experiments. It examines some of the theoretical perspectives behind data collection and human performance assessment, and argues for a high resemblance of the real world and use of subject matter expertise in simulator studies. A model is proposed, suggesting that human performance measurement should be tightly coupled to the topic of study and have a close connection to the time line. This coupling requires new techniques for continuous data collection, and eye movement tracking has been identified as a promising basis for this type of measures. One way of improving realism is to create virtual environments allowing for controlling more of the environment surrounding the test subjects. New application areas for virtual environments are discussed for use in control room and field studies. The combination of wearable computing, virtual and augmented (the use of computers to overlay virtual information onto the real world) reality provides many new possibilities to present information to operators. In two experiments, virtual and augmented reality techniques were used to visualise radiation fields for operators in a contaminated nuclear environment. This way the operators could train for and execute their tasks in a way that minimised radiation exposure to the individual operator. Both experiments were successful in proving the concept of radiation visualisation. Virtual environments allow for early end-user feedback in the design and refurbishment of control room man-machine interfaces. The practical usability of VR in the control room setting was tested in two control room design experiments. The results show that with the right tools for solving the tasks under test, even desktop presentations of the virtual environment can provide sufficient resemblance of the real world.

    The High Altitude Balloon Experiment demonstration of Acquisition, Tracking, and Pointing (HABE-ATP) is a system built around balloon-borne payload which is carried to a nominal 26-km altitude. The goal is laser tracking thrusting theater and strategic missiles, and then pointing a surrogate laser weapon beam, with performance levels end a timeline traceable to operational laser weapon system requirements. This goal leads to an experiment system design which combines hardware from many technology areas: an optical telescope and IR sensors; an advanced angular inertial reference; a flexible multi-level of actuation digital control system; digital tracking processors which incorporate real-time image analysis and a pulsed, diode-pumped solid state tracking laser. The system components have been selected to meet the overall experiment goals of tracking unmodified boosters at 50- 200 km range. The ATP system on HABE must stabilize and control a relative line of sight between the platform and the unmodified target booster to a 1 microrad accuracy. The angular pointing reference system supports both open loop and closed loop track modes; GPS provides absolute position reference. The control system which positions the line of sight for the ATP system must sequence through accepting a state vector handoff, closed-loop passive IR acquisition, passive IR intermediate fine track, active fine track, and then finally aimpoint determination and maintenance modes. Line of sight stabilization to fine accuracy levels is accomplished by actuating wide bandwidth fast steering mirrors (FSM's). These control loops off-load large-amplitude errors to the outer gimbal in order to remain within the limited angular throw of the FSM's. The SWIR acquisition and MWIR intermediate fine track sensors (both PtSi focal planes) image the signature of the rocket plume. After Hard Body Handover (HBHO), active fine tracking is conducted with a visible focal plane viewing the laser-illuminated target

SC is often used to monitor stress as it is connected to the activation of the sympathetic nervous system (SNS). By including BVP into the model we introduce information about para-sympathetic activation, which offers a more complete view of the psycho...

    Full Text Available Abstract Background Translational research typically requires data abstracted from medical records as well as data collected specifically for research. Unfortunately, many data within electronic health records are represented as text that is not amenable to aggregation for analyses. We present a scalable open source SQL Server Integration Services package, called Regextractor, for including regular expression parsers into a classic extract, transform, and load workflow. We have used Regextractor to abstract discrete data from textual reports from a number of ‘machine generated’ sources. To validate this package, we created a pulmonary function test data mart and analyzed the quality of the data mart versus manual chart review. Methods Eleven variables from pulmonary function tests performed closest to the initial clinical evaluation date were studied for 100 randomly selected subjects with scleroderma. One research assistant manually reviewed, abstracted, and entered relevant data into a database. Correlation with data obtained from the automated pulmonary function test data mart within the Northwestern Medical Enterprise Data Warehouse was determined. Results There was a near perfect (99.5% agreement between results generated from the Regextractor package and those obtained via manual chart abstraction. The pulmonary function test data mart has been used subsequently to monitor disease progression of patients in the Northwestern Scleroderma Registry. In addition to the pulmonary function test example presented in this manuscript, the Regextractor package has been used to create cardiac catheterization and echocardiography data marts. The Regextractor package was released as open source software in October 2009 and has been downloaded 552 times as of 6/1/2012. Conclusions Collaboration between clinical researchers and biomedical informatics experts enabled the development and validation of a tool (Regextractor to parse, abstract and assemble

At low concentrations (H2 internal antenna or connection to an external antenna, a microcontroller, an electronic circuit for interfacing with the sensors and an energy source, usually a battery or an embedded form of energy harvesting. All nodes are equal and serve as routers, so there is no need to plan nodes placement in advance Mesh Network protocol. Every node maintains a local routing table with information about one or several neighbors. The signal transmission between nodes and router used radio channel 2.6 GHz. Communication between router and IT server used two methods: cable RS486 and GPRS modem. GPRS connection is unstable and influence on operating stability. There are some problems in using of directional antenna because of the high level of city's radio noises and radio interferences. Nevertheless, a number of experiments with use of different technical solutions allowed us to perform continuous monitoring during 2 months. As a result about 3 million data records were obtained during experimental works. This information provided an opportunity to develop the structure of database management systems to store data and the technology of online data collection from remote sensors. Using the abilities of program software a periodical (12h) automatic export/import was realized. Access to file on remote computers is opened using FTP protocol. Database forms derived tables for each sensors. We use triggers to modify data, for example, to modify signal from gas sensors to gas concentration, in depend of unique sensor name. Additional table gives geographical coordinates of each node. We use GIS project for visualization and data analysis. Experiences revealed the inverse relationship between H2 concentration and temperature and pressure. Also we revealed periodicity of gas

    This paper estimates the effect of Wal-Mart expansion on retail employment at the county level. Using an instrumental-variables approach to correct for both measurement error in entry dates and endogeneity of the timing of entry, I find that Wal-Mart entry increases retail employment by 100 jobs in the year of entry. Half of this gain disappears over the next five years as other retail establishments exit and contract, leaving a long-run statistically significant net gain of 50 jobs. Wholesal...

    1979-01-01

    The performance characteristics of the transmitter experiment package (TEP) aboard the Communications Technology Satellite (CTS) measured during its first 2 years in orbit are presented. The TEP consists of a nominal 200 watt output stage tube (OST), a supporting power processing system (PPS), and a variable conductance heat pipe system (VCHPS). The OST, a traveling wave tube augmented with a 10 stage depressed collector has an overall saturated average efficiency of 51.5 percent and an average saturated radio frequency (rf) output power at center band frequency of 240 watts. The PPS operated with a measured efficiency of 86.5 to 88.5 percent. The VCHPS, using three pipes to conduct heat from the PPS and the OST to a 52 by 124 centimeter radiator fin, maintained the PPS baseplate temperature below 50 C for all operating conditions. The TEP performance characteristics presented include frequency response, rf output power, thermal performance, and efficiency. Communications characteristics were evaluated by using both video and audio modulated signals. On four occasions, the TEP experienced temporary thermal control system malfunctions. The anomalies were terminated safely, and the problem was investigated because of the potential for TEP damage due to the signficant temperature increases. Safe TEP operating procedures were established.

    Full Text Available Aim: To analyse teachers’ experience in applying information communication technologies (from now on referred to as ICT during the study process. Methodology: The analysis is based on a qualitative research methodology determined by the novelty of the problem under analysis. Six teachers of the University X (faculty Y participating in the study were selected by applying a random sampling procedure and were interviewed by using the semi-structured interviews. Results: The research revealed that the use of ICT in the study process is still fragmented due to the lack of the teachers` ICT competence and to teaching priority given to direct communication. Because of the lack of higher level competence in ICT necessary for the efficient use of ICT tools in the study process, teachers as a rule resort to limited opportunities to increase the attractiveness of the process. Research limitations: in order to theoretically and empirically validate ICT applicationpossibilities in the study process, teachers of one faculty of one university have been interviewed. In view of this, the conclusions cannot be extended to all teachers. Practical significance: the research revealed problems faced by the university teachers in applying ICT during the study process. Identification of problems will facilitate a more efficient use of ICT in the study process, as well as the development of teachers’ qualification. Originality and value: the research provided more information on teachers` competence in using ICT.

    This multi-authored textbook addresses graduate students with a background in physics, mathematics or computer science. No research experience is necessary. Consequently, rather than comprehensively reviewing the vast body of knowledge and literature gathered in the past twenty years, this book concentrates on a number of carefully selected aspects of quantum information theory and technology. Given the highly interdisciplinary nature of the subject, the multi-authored approach brings together different points of view from various renowned experts, providing a coherent picture of the subject matter. The book consists of ten chapters and includes examples, problems, and exercises. The first five present the mathematical tools required for a full comprehension of various aspects of quantum mechanics, classical information, and coding theory. Chapter 6 deals with the manipulation and transmission of information in the quantum realm. Chapters 7 and 8 discuss experimental implementations of quantum information ideas using photons and atoms. Finally, chapters 9 and 10 address ground-breaking applications in cryptography and computation. (orig.)

    We have been developing a laser-cooling apparatus for flight on the International Space Station (ISS), with the intention of demonstrating linewidths on the cesium clock transition narrower than can be realized on the ground. GLACE (the Glovebox Laser- cooled Atomic Clock Experiment) is scheduled for launch on Utilization Flight 3 (UF3) in 2002, and will be mounted in one of the ISS Glovebox platforms for an anticipated 2-3 week run. Separate flight definition projects funded at NIST and Yale by the Micro- gravity Research Division of NASA as a part of its Laser Cooling and Atomic Physics (LCAP) program will follow GLACE. Core technologies for these and other LCAP missions are being developed at JPL, with the current emphasis on developing components such as the laser and optics subsystem, and non-magnetic vacuum-compatible mechanical shutters. Significant technical challenges in developing a space qualifiable laser cooling apparatus include reducing the volume, mass, and power requirements, while increasing the ruggedness and reliability in order to both withstand typical launch conditions and achieve several months of unattended operation. This work was performed at the Jet Propulsion Laboratory under a contract with the National Aeronautics and Space Administration.

    Attalea phalerata Mart. ex Spreng. (Arecaceae), popularly known as “bacuri”, is used in Brazilian folk medicine. Its oil is used orally to relieve pulmonary congestion and joint pain. In topical applications, it is applied as an effective hair tonic and anti-dandruff. The in natura pulp and its nuts are used as food because of its nutritional value. Despite its use in folk medicine, there is a lack of data regarding its in vivo/in vitro cytotoxic/genotoxic and clastogenic effects. Therefore, in this study, we evaluated the cytotoxic, genotoxic and clastogenic effects of Attalea phalerata Mart. ex Spreng. oil (APMO) in vitro and in vivo. For the analysis of cytotoxic potential, the Artemia salina and MTT (3-(4,5-dimethizzol-zyl)-2,5-diphenyltetrazolium bromide) assays were performed. Possible cytotoxic, genotoxic and clastogenic effects of APMO intake were determined by performing the comet and micronucleus assays. Male and female Wistar rats were orally treated with doses of 125, 250, 500 or 1000 mg.kg-1 of the APMO daily for 28 consecutive days (four weeks). The results showed that the APMO did not induce cell death in the experiments of Artemia salina and MTT, indicating that it has no cytotoxicity. The APMO did not cause significant damage to the DNA of the rats in the four doses used when compared to the negative control group (saline + Tween® 80). The APMO did not present any significant increase in micronucleated polychromatic erythrocytes (MNPCEs) for the four tested doses. When compared to the positive control group, all groups (comet and micronucleus tests) were statistically different. These data suggest that the administration of Attalea phalerata Mart oil. ex Spreng does not cause cytotoxicity, genotoxicity and clastogenicity in experimental models in vitro and in vivo following oral administration in this study.

    Public engagement with science and technology is now widely used in science policy and communication. Touted as a means of enhancing democratic discussion of science and technology, analysis of public engagement with science and technology has shown that it is often weakly tied to scientific governance. In this article, we suggest that the notion of capacity building might be a way of reframing the democratic potential of public engagement with science and technology activities. Drawing on literatures from public policy and administration, we outline how public engagement with science and technology might build citizen capacity, before using the notion of capacity building to develop five principles for the design of public engagement with science and technology. We demonstrate the use of these principles through a discussion of the development and realization of the pilot for a large-scale public engagement with science and technology activity, the Futurescape City Tours, which was carried out in Arizona in 2012.

  10. The Teacher Technology Integration Experience: Practice and Reflection in the Classroom

    Directory of Open Access Journals (Sweden)

    Dana Ruggiero

    2015-05-01

    Full Text Available Previous studies indicated that the technology integration practices of teachers in the classroom often did not match their teaching styles. Researchers concluded that this was due, at least partially, to external barriers that prevented teachers from using technology in ways that matched their practiced teaching style. Many of these barriers, such as professional support and access to hardware and software, have been largely diminished over the last twenty years due to an influx of money and strategies for enhancing technology in primary and secondary schools in the United States. This mixed-methods research study was designed to examine the question, “What technology do teachers use and how do they use that technology to facilitate student learning?” K-12 classroom teachers were purposefully selected based on their full-time employment in a public, private, or religious school in a Midwestern state in the United States, supported by the endorsement of a school official. There were 1048 teachers from over 100 school corporations who completed an online survey consisting of six questions about classroom technology tools and professional development involving technology. Survey results suggest that technology integration is pervasive in the classroom with the most often used technology tool identified as PowerPoint. Moreover, teachers identified that training about technology is most effective when it is contextually based in their own classroom. Follow-up interviews were conducted with ten percent (n=111 of the teachers in order to examine the relationship between teachers’ daily classroom use of technology and their pedagogical practices. Results suggest a close relationship; for example, teachers with student-centric technology activities were supported by student-centric pedagogical practices in other areas. Moreover, teachers with strongly student-centered practices tended to exhibit a more pronounced need to create learning

    2010-01-01

    The development and dissemination of sawah rice eco-technology in Nigeria and Ghana as prerequisites for the actualization of green revolution in West Africa were described. It showed that the neglect of the eco-technology and the overemphasis of the biotechnology have rendered the ineffective transferability of the green revolution process from Asia to Africa. The sawah eco-technology increases yield up to 5 t/hm2 through bunding and the use of inlet and outlet connecting irrigation and drainage, which enhances effective water control and management, improves the efficiency of fertilizer, improves nitrogen fixation by soil microbes and algae, increases the use of wetlands, improves soil organic matter accumulation, suppresses weed growth, and enhances immune mechanism of rice through nutrient supply. The current experience has therefore established that the technology overcomes the constraints that have limited the realization of green revolution in West Africa.

    2016-12-01

    SOFIA, an 80/20 partnership of NASA and the German Aerospace Center (DLR), consists of a modified Boeing 747SP carrying a reflecting telescope with an effective diameter of 2.5 meters. SOFIA is the largest airborne observatory in the world, capable of observations impossible for even the largest and highest ground-based telescopes. The SOFIA Program Office is at NASA ARC, Moffett Field, CA; the aircraft is based in Palmdale, CA. During its planned 20-year lifetime, SOFIA will foster development of new scientific instrumentation and inspire the education of young scientists and engineers. Astrophysicists are awarded time on SOFIA to study many kinds of astronomical objects and phenomena. Among the most interesting are: Star birth, evolution, and death Formation of new planetary systems Chemistry of complex molecules in space Planet and exoplanet atmospheres Galactic gas & dust "ecosystems" Environments around supermassive black holes SOFIA currently has eight instruments, five US-made and three German. The instruments — cameras, spectrometers, and a photometer,— operate at near-, mid- and far-infrared wavelengths, each spectral range being best suited to studying particular celestial phenomena. NASA's Airborne Astronomy Ambassadors' (AAAs) experience includes a STEM immersion component. AAAs are onboard during two overnight SOFIA flights that provide insight into the acquisition of scientific data as well as the interfaces between the telescope, instrument, & aircraft. AAAs monitor system performance and view observation targets from their dedicated workstation during flights. Future opportunities for school district partnerships leading to selection of future AAA cohorts will be offered in 2018-19. AAAs may access public archive data via the SOFIA Data Cycle System (DCS) https://dcs.sofia.usra.edu/. Additional SOFIA science and other resources are available at: www.sofia.usra.edu, including lessons that use photovoltaic circuits, and other technology for the

    2010-01-01

    A 3-month-long, large-scale flume experiment involving research and testing of selected conventional and surrogate bedload-monitoring technologies was conducted in the Main Channel at the St. Anthony Falls Laboratory under the auspices of the National Center for Earth-surface Dynamics. These experiments, dubbed StreamLab06, involved 25 researchers and volunteers from academia, government, and the private sector. The research channel was equipped with a sediment-recirculation system and a sediment-flux monitoring system that allowed continuous measurement of sediment flux in the flume and provided a data set by which samplers were evaluated. Selected bedload-measurement technologies were tested under a range of flow and sediment-transport conditions. The experiment was conducted in two phases. The bed material in phase I was well-sorted siliceous sand (0.6-1.8 mm median diameter). A gravel mixture (1-32 mm median diameter) composed the bed material in phase II. Four conventional bedload samplers – a standard Helley-Smith, Elwha, BLH-84, and Toutle River II (TR-2) sampler – were manually deployed as part of both experiment phases. Bedload traps were deployed in study Phase II. Two surrogate bedload samplers – stationarymounted down-looking 600 kHz and 1200 kHz acoustic Doppler current profilers – were deployed in experiment phase II. This paper presents an overview of the experiment including the specific data-collection technologies used and the ambient hydraulic, sediment-transport and environmental conditions measured as part of the experiment. All data collected as part of the StreamLab06 experiments are, or will be available to the research community.

  1. Euterpe oleracea Mart. extract prevents vascular remodeling and endothelial dysfunction in spontaneously hypertensive rats

    Full Text Available Summary. We assessed the effects of Euterpe oleracea Mart. (açaí seed extract (ASE rich in proanthocyanidins and catechin on vascular dysfunction and oxidative stress associated with hypertension in spontaneously hypertensive rats (SHR. SHR and control rats were treated with ASE (200 mg/kg/day or vehicle for 10 weeks. In the rat mesenteric arterial bed (MAB, acetylcholine response, endothelial nitric oxide synthase (eNOS and superoxide dismutase 1 (SOD 1 expressions were studied. The antioxidant enzyme activity, oxidative damage and nitrite quantification were assessed in MAB and heart homogenates. eNOS immunohistochemistry and histological analysis was carried out on aortic sections. ASE was able to attenuate the hypertension and prevent the endothelial dysfunction in MAB of SHR. The increased levels of protein carbonylation and associated low levels of nitrite in MAB and heart of SHR were attenuated by ASE. The up-regulation of eNOS and SOD1 expression and the increased activity of SOD in MAB from SHR were normalized by ASE. In aorta from SHR, ASE prevented the increase in media thickness, media:lumen ratio and the decrease in the percentage of elastic fibers. Our results suggest that ASE produces antihypertensive effect and prevents the vascular dysfunction in SHR, through mechanisms involving antioxidant effects and NO production. Industrial relevance. Euterpe oleracea Mart. (Açaí has been considered one of the most important medicinal plants of the Amazon by its beneficial effects in the treatment of fever, pain, inflammation and anemia. More recently, Euterpe oleracea Mart. has been reported to reduce blood pressure with an important antioxidant property. The present research reports the protective effect of the extract of the seeds from Euterpe oleraca Mart. against high blood pressure and the associated vascular structural and functional changes.

  2. Etnocentrismo, racismo y miedo: los indígenas y los incultos en Martí

    Directory of Open Access Journals (Sweden)

    Jorge Camacho

    2010-04-01

    Full Text Available In the following article I return to the idea of ethnicity and liberalism in Latin America during the last part of the 19th century. I also discuss Martí’s view of the Indians after 1885, when his chronicles were fueled by the rhetoric of pro-indigenous groups such as the Friends of Indians Association. I propose to look at other ways in which Martí’s ethnocentric view of culture and race intertwined with his agenda of “defending” the Indians, especially in his essay “Nuestra América.” For that purpose I retrace some of my previous arguments and discuss other essays that have recently elaborated on Martí’s “other side”, the one that imposes on the Indians his own liberal agenda, and the vision of modernity that the elites were constructing in Latin America at the end of 19th century. In my previous articles I discussed Martí’s chronicles on the Guatemalan, Mexican and American Indians and here I will focus on the similarities between the positivists in Mexico and Martí’s emphasis on “scientific politics” as well as his fear that those that were at the lowest level of society could one day revolt against the republic and destroy the justice “accumulated in books.” For books symbolized for Martí the “lettered elite”, those that had power and exercised it to their own advantage. He talked about this fear in Mexico, and in his most famous essay he returned to it again with a somewhat different perspective, but still with the conviction that within a democracy everything could be solved and a revolt from the “unlettered” masses was not justified. I argue that even if “Nuestra América” meant a more positive view of the “Indian problem”, Martí still considers the Indians, the “gauchos” and the rest of the “incultos” as a threat. They were the natural ally of the “caudillos” that ruled for so long Latin America, charismatic caudillos such as Juan Manuel de Rosas.

    NLP technologies can play a significant role in healthcare where a predominant segment of the clinical documentation is in text form. In a graduate course focused on understanding semantic web services at West Virginia University, a class project was designed with the purpose of exploring potential use for NLP-based abstraction of clinical documentation. The role of NLP-technology was simulated using human abstractors and various workflows were investigated using public domain workflow and semantic web service technologies. This poster explores the potential use of NLP and the role of workflow and semantic web technologies in developing healthcare IT environments.

    Full Text Available Science and technology engendered unexpected social, political and health related problems. These included corrupt and dubious utilization of information and communication technology, environmental pollution and protection and depletion of the ozone layer which endangered human health. This sstudy examined the positive and negative implications of science and technology in Africa using Nigeria as a case study. This attempt became germane owing to the important place of the scientific and technological enterprise in the entire pattern of human life. The critical and conceptual methods of analysis were employed and the available literatures on the problem provided the background for the study. The study showed the dangers in uncontrolled destructive character of scientific and technological knowledge to human survival and suggested appropriate control measures. The study, therefore, suggested resource control, the control of chemical and biological weapons and the abuse of information and communication technology. Manufacturers of various technologies needed to create subsidiary technology and put in place necessary mechanisms for curtailing the foreseeable consequences of their products. Indeed, technological civilization should not be blindly embraced.

    Full Text Available RESUMO Os frutos do açaizeiro (Euterpe oleracea Mart. e da bacabeira ( MOenocarpus bacabaart, duas palmeiras tropicais nativas e socioeconomicamente importantes para os estados Amazônicos, são utilizados na produção de polpas processadas em sistemas agrofamiliares. Nesse sentido, o presente estudo objetivou a avaliação da qualidade físico-química e funcional de polpas de açaí e bacaba processadas artesanalmente. Os frutos foram coletados em propriedades rurais do município do Cantá/Roraima (bacaba e Boa Vista/ Roraima (açaí. Para a constituição do experimento, as polpas processadas foram armazenadas em pequenas embalagens de politereftalato de etileno (PET transparente e com tampa (mesmo material, com capacidade de 145 mL e refrigeradas a 3 ± 0,2°C e 45% de U.R., durante 5 dias. Foram analisados os seguintes parâmetros: pH, acidez titulável (AT, sólidos solúveis (SS, relação SS/AT, açúcares totais e redutores, pectinas totais e solúveis, teor de antocianinas e fenólicos totais. Ao final, para as polpas de açaí, levando-se em consideração os limites estabelecidos pelo Padrão de Identidade e Qualidade (PIQ, apenas o parâmetro AT apresentou-se fora da instrução normativa. Entretanto, a inexistência de padrões para bacaba inviabilizou tal comparação. Quanto ao teor das pectinas totais, pode-se concluir que ambas as polpas apresentam baixas concentrações desse componente, não sendo indicadas para produção de doces e geleias sem adição de agentes geleificantes. Os teores de compostos fenólicos e de antocianinas, em ambas as polpas, apesar de diminuir com o período de armazenamento refrigerado, apresentam altas concentrações quando em comparação a outros alimentos com apelo funcional.

    Michailov, B. P.; Torchinova, R. S.; Bychkova, M. I.

    On board the orbital complex "Salyut-6-Soyuz" during long-term near 0-gravity space flight the technological experiments on synthesis of the superconducting MoGa 5, MO 3Ga and Nb 3Sn intermetallic compounds by means of liquid-phase diffusion and on bulk crystallization of the hypoeutectic superconducting Pb-Sn alloy and magnetically ordered Gd 3Co and (Gd 0.2Tb 0.8) 3Co compounds have been performed. During the process of the liquid-phase diffusion considerable changes of the formation of the reaction layers (mechanisms, phase composition, thickness, etc.) in the superconducting Mo-Ga and Nb-Sn systems were observed. MoGa 5, Nb 6Sn 5 and NbSn 2 phases were found in the ground-based samples while in the flight samples the formation of MoGa 5, Mo 3Ga, Nb 3Sn and Nb 6Sn 5 phases was observed. As a result of the changes of the phase composition of the diffusion layers in the flight samples two superconducting transitions at 18.3 and 5.7 K were established (only one transition at 6.9K was measured for the ground-based sample) (Savitsky et al., Izv. Akad. Nauk SSSR, Metals5, 224-232, 1982; Zemskov et al., Izv. Akad. Nauk SSSR, Physics49, 673-680, 1985). Considerable increasing of the critical current measured for the Pb-Sn flight sample has been observed (Savitsky et al., Dokl. Akad. Nauk SSSR257, 102-104, 1981; Zemskov et al., 1985). Better homogeneity and crystal structure perfection of the flight Gd 3Co and (Gd 0.2Tb 0.8) 3Co samples have been established by means of the micro-zonde and low-temperature X-ray technique (Savitsky et al., Acta Astronautica11, 691-696, 1984; Zemskov et al., 1985). Different behaviour of the ground-based and flight samples in the process of magnetization and the displacements of the temperatures of the magnetic phase transitions have been observed.

    Full Text Available A experiência do espaço urbano tem sofrido alterações operadas por extensões, expansões e simulaçõesem virtude da incorporação do desenvolvimento tecnológico à própria constituição física e à linguagemda cidade. Entre cidade e experiência, a interface tecnológica se apresenta como possibilidade de reconhecimento,conhecimento e produção das relações espaciais reais e potenciais das cidades contemporâneas.Desde a concepção do mundo urbano, que, segundo Henri Lefebvre (1991, esteve relacionada diretamentecom o período industrial, a tecnologia tem delimitado e pontuado as diversas fases e consequentes camadasque formam a cidade, tanto em relação à dinâmica física do espaço, como em relação à sua representação.Se de fato a tecnologia sempre esteve vinculada diretamente à própria construção das cidades, por meio deiniciativas dos governos e de grandes empresas, é na sua condição atual que se potencializa como mediaçãoentre o indivíduo e o espaço urbano, este cada vez mais tecnologicamente hibridizado. Destarte, este artigotem por objetivo discutir de que modo a tecnologia tem estabelecido novas mediações e respectivas configuraçõesno espaço urbano das cidades contemporâneas, de modo a não ser mais possível dissociá-la destecontexto. Para tal propósito, tomam-se como referência projetos ou iniciativas de pesquisa que buscam nastecnologias de informação e comunicação (TICs novos meios de extensão da cidade, em interface com ambientesurbanos geolocalizados ou virtuais.

  20. Smart home technology for safety and functional independence: the UK experience.

    This paper proposes that people with neurological conditions can be successfully supported by smart homes only when their needs and aspirations of the technological interventions are fully understood and integrated in the design. A neurological condition can and does provide a clue to the finished technological design but this alone fails to personalise the system and stands to be rejected by the person who requires the technology. This paper explores the underlying issues of the complexity of this design process when designing for people with neurological conditions, and advances a matrix to facilitate the assessment process to maintain a person-centred design of any system.
