  12. Technology, world politics, and American policy

    Energy Technology Data Exchange (ETDEWEB)

    Basiuk, V.

    1977-01-01

    This book concentrates on modern technology, analyzing its present and future impact on international relations. Beginning with the socio-political impact of technological trends around the world, Dr. Basiuk examines the aspects of future military (nuclear and ''conventional'') technology that will likely reinforce the growing stalemate between the U. S. and USSR. He surveys the integrative power of technology which is ''shrinking'' the modern world into global interdependence devoting detailed chapters to an assessment of the major strengths and weaknesses that characterize the ability of the United States, the Soviet Union, Western Europe, and Japan to deal with the problems arising from future developments in science and technology. As technology changes societies, ''power over'' people is becoming less important, while ''power toward,'' the ability to lead people and mobilize resources for the solution of contemporary problems and toward new frontiers of human achievement, tends to gain. Although technological impact can modify the international system, leading to transnationalism and a proliferation of actors on the global scene, nation-states will remain a principal element in world politics for some time to come. The current role of technology in America's domestic, foreign, and security policies is discussed. The final section examines the complexities of the postindustrial society. Projecting the direction of societal development well into the twenty-first century, Dr. Basiuk identifies two seemingly contradictory trends: the need for strengthening scientific and technological policy to achieve higher levels of material capability, accompanied by a reorientation in values to a limited-growth, semistationary society which de-emphasizes material rewards.

    The early 21st century has magnified the dangers posed by proliferation of weapons of mass destruction (WMD). Nonetheless, cooperative efforts to thwart this trade have grown considerably more difficult and the challenges more complicated. The ubiquitous nature of dual-use technology, the application of terrorist tactics for mass destruction on 9/11, the emergence of a more unilateralist US foreign policy, and the world's ever-expanding economic relations have all made more arduous the task of stemming proliferation of WMD, their precursors, and delivery systems. All of these challenges have been highlighted in recent years, but it is the last of these - the changing nature of the global economy- that is perhaps least analyzed but also most essential to improving international cooperation on nonproliferation. Many of today's proliferation concerns are familiar problems exacerbated by accelerating levels of international trade and investment. For example, controlling sensitive exports has become more complicated as officials, industry leaders, and nonproliferation experts must struggle simultaneously to find ways to ensure the flow of exports to legitimate buyers and supply chain partners who increasingly span the globe. Similarly, competitive enterprises today place a premium on rapid delivery and the speed of transactions. This in turn has increased pressures placed on officials around the world to reduce the time they spend evaluating each licensing decision, even as these assessments become more difficult as global investors move deeper into the developing world. Furthermore, the emergence of developing economies as second-tier suppliers with the potential to transship critically sensitive technologies to third parties is another complicating factor and a consequence of the globalizing economy. Science, technology, and industry research and development activities with dual-use applications are also becoming increasingly international endeavors, facilitated

    For the past three decades, Earth science remote sensing technologies have been providing enormous amounts of useful data and information in broadening our understanding of our home planet as a system. This research, as it has expanded our learning process, has also generated additional questions. This has further resulted in establishing new science requirements, which have culminated in defining and pushing the state-of-the-art technology needs. NASA s Earth science program has deployed 18 highly complex satellites, with a total of 80 sensors, so far and is in a process of defining and launching multiple observing systems in the next decade. Due to the heightened security alert of the nation, researchers and technologists are paying serious attention to the use of these science driven technologies for dual use. In other words, how such sophisticated observing and measuring systems can be used in detecting multiple types of security concerns with a substantial lead time so that the appropriate law enforcement agencies can take adequate steps to defuse any potential risky scenarios. This paper examines numerous NASA technologies such as laser/lidar systems, microwave and millimeter wave technologies, optical observing systems, high performance computational techniques for rapid analyses, and imaging products that can have a tremendous pay off for security applications.

    This is the final report of a one-year Laboratory-Directed Research and Development (LDRD) Project at the Los Alamos National Laboratory (LANL). This project investigated separations technology development needed for accelerator-driven transmutation technology (ADTT) concepts, particularly those associated with plutonium disposition (accelerator-based conversion, ABC) and high-level radioactive waste transmutation (accelerator transmutation of waste, ATW). Specific focus areas included separations needed for preparation of feeds to ABC and ATW systems, for example from spent reactor fuel sources, those required within an ABC/ATW system for material recycle and recovery of key long-lived radionuclides for further transmutation, and those required for reuse and cleanup of molten fluoride salts. The project also featured beginning experimental development in areas associated with a small molten-salt test loop and exploratory centrifugal separations systems

    Highlights: • Renewable energy-driven desalination technologies are highlighted. • Solar, geothermal, and wind energy sources were explored. • An innovative hybrid approach (combined solar–geothermal) has also been explored. • Innovative desalination technologies developed by our group are discussed. • Climate change and GHG emissions from desalination are also discussed. - Abstract: Globally, the Kingdom of Saudi Arabia (KSA) desalinates the largest capacity of seawater but through energy-intensive thermal processes such as multi-stage flash (MSF) distillation (>10 kW h per m 3 of desalinated water, including electrical and thermal energies). In other regions where fossil energy is more expensive and not subsidized, seawater reverse osmosis (SWRO) is the most common desalination technology but it is still energy-intensive (3–4 kW h e /m 3 ). Both processes therefore lead to the emission of significant amounts of greenhouse gases (GHGs). Moreover, MSF and SWRO technologies are most often used for large desalination facilities serving urban centers with centralized water distribution systems and power grids. While renewable energy (RE) sources could be used to serve centralized systems in urban centers and thus provide an opportunity to make desalination greener, they are mostly used to serve rural communities off of the grid. In the KSA, solar and geothermal energy are of most relevance in terms of local conditions. Our group is focusing on developing new desalination processes, adsorption desalination (AD) and membrane distillation (MD), which can be driven by waste heat, geothermal or solar energy. A demonstration solar-powered AD facility has been constructed and a life cycle assessment showed that a specific energy consumption of <1.5 kW h e /m 3 is possible. An innovative hybrid approach has also been explored which would combine solar and geothermal energy using an alternating 12-h cycle to reduce the probability of depleting the heat source

    The purpose of this research project was to develop an improved understanding of how electrically driven processes, including electrocoalescence, acoustic agglomeration, and electric filtration, may be employed to efficiently treat problems caused by the formation of aerosols during DOE waste treatment operations. The production of aerosols during treatment and retrieval operations in radioactive waste tanks and during thermal treatment operations such as calcination presents a significant problem of cost, worker exposure, potential for release, and increased waste volume. There was anecdotal evidence in the literature that acoustic agglomeration and electrical coalescence could be used together to change the size distribution of aerosol particles in such a way as to promote easier filtration and less frequent maintenance of filtration systems. As such, those electrically driven technologies could potentially be used as remote technologies for improved treatment; however, existing theoretical models are not suitable for prediction and design. To investigate the physics of such systems, and also to prototype a system for such processes, a collaborative project was undertaken between Oak Ridge National Laboratory (ORNL) and the University of Texas at Austin (UT). ORNL was responsible for the larger-scale prototyping portion of the project, while UT was primarily responsible for the detailed physics in smaller scale unit reactors. It was found that both electrical coalescence and acoustic agglomeration do in fact increase the rate of aggregation of aerosols. Electrical coalescence requires significantly less input power than acoustic agglomeration, but it is much less effective in its ability to aggregate/coalesce aerosols. The larger-scale prototype showed qualitatively similar results as the unit reactor tests, but presented more difficulty in interpretation of the results because of the complex multi-physics coupling that necessarily occur in all larger

    The development of civilisation is linked inextricably with growing demand for electricity. Thus, the still-rapid increase in the level of utilisation of natural resources, including fossil fuels, leaves it more and more urgent that conventional energy technologies and the potential of the renewable energy sources be made subject to re-evaluation. It is estimated that last 200 years have seen use made of more than 50% of the available natural resources. Equally, if economic forecasts prove accurate, for at least several more decades, oil, natural gas and coal will go on being the basic primary energy sources. The alternative solution represented by nuclear energy remains a cause of considerable public concern, while the potential for use to be made of renewable energy sources is seen to be very much dependent on local environmental conditions. For this reason, it is necessary to emphasise the impact of research that focuses on the further sharpening-up of energy efficiency, as well as actions aimed at increasing society's awareness of the relevant issues. The history of recent centuries has shown that rapid economic and social transformation followed on from the industrial and technological revolutions, which is to say revolutions made possible by the development of power-supply technologies. While the 19th century was "the age of steam" or of coal, and the 20th century the era of oil and gas, the question now concerns the name that will at some point come to be associated with the 21st century. In this paper, the subjects of discussion are primary energy consumption and energy resources, though three international projects on the global scale are also presented, i.e. ITER, Hydrates and DESERTEC. These projects demonstrate new scientific and technical possibilities, though it is unlikely that commercialisation would prove feasible before 2050. Research should thus be focused on raising energy efficiency. The development of high-efficiency technologies that

    In December, 2011, over 800 people experienced the exhibit, :"der"//pattern for a virtual environment, created for the fully immersive CAVETM at the University of Wisconsin-Madison. This exhibition took my nature-based photographic work and reinterpreted it for virtual reality (VR).Varied responses such as: "It's like a moment of joy," or "I had to see it twice," or "I'm still thinking about it weeks later" were common. Although an implied goal of my 2D artwork is to create a connection that makes viewers more aware of what it means to be a part of the natural world, these six VR environments opened up an unexpected area of inquiry that my 2D work has not. Even as the experience was mediated by machines, there was a softening at the interface between technology and human sensibility. Somehow, for some people, through the unlikely auspices of a computer-driven environment, the project spoke to a human essence that they connected with in a way that went beyond all expectations and felt completely out of my hands. Other interesting behaviors were noted: in some scenarios some spoke of intense anxiety, acrophobia, claustrophobia-even fear of death when the scene took them underground. These environments were believable enough to cause extreme responses and disorientation for some people; were fun, pleasant and wonder-filled for most; and were liberating, poetic and meditative for many others. The exhibition seemed to promote imaginative skills, creativity, emotional insight, and environmental sensitivity. It also revealed the CAVETM to be a powerful tool that can encourage uniquely productive experiences. Quite by accident, I watched as these nature-based environments revealed and articulated an essential relationship between the human spirit and the physical world. The CAVETM is certainly not a natural space, but there is clear potential to explore virtual environments as a path to better and deeper connections between people and nature.

    This article reviews major developments in etch- and deposition-driven plasma source technology over the past decades. We first review the radio-frequency parallel plate diode, summarizing its great impact but also its inherent problems. Ensuing sections then treat microwave plasma generation, electron cyclotron resonance power transfer enhancement, inductively coupled plasma sources, and (very briefly) the radio-frequency helicon source. We then introduce the important and relatively new issues of control of the ion energy distribution function and the tailoring of plasma chemistry, including the decoupling of chemistry from pressure and power. The emerging areas of ambient pressure plasma sources and miniature ``plasmas on a chip'' are summarized, and we conclude with a brief view to the future.

    A fusion-driven hybrid subcritical system (FDS) concept has been designed and proposed as spent fuel burner based on viable technologies. The plasma fusion driver can be designed based on relatively easily achieved plasma parameters extrapolated from the successful operation of existing fusion experimental devices such as the EAST tokamak in China and other tokamaks in the world, and the subcritical fission blanket can be designed based on the well-developed technologies of fission power plants. The simulation calculations and performance analyses of plasma physics, neutronics, thermal-hydraulics, thermomechanics and safety have shown that the proposed concept can meet the requirements of tritium self-sufficiency and sufficient energy gain as well as effective burning of nuclear waste from fission power plants and efficient breeding of nuclear fuel to feed fission power plants.

    2003-01-01

    Starting from a set of clear key assumptions on economic activity, population and hydrocarbon resources, WETO describes in detail scenarios for the evolution of World and European energy systems, power generation technologies and impacts of climate change policy in the main world regions or countries.It presents a coherent framework to analyse the energy, technology and environment trends and issues over the period to 2030, focusing on Europe in a world context. Three of the key results of this work are: (1) in a Reference scenario, i.e.if no strong specific policy initiatives and measures are taken, world CO2 emissions are expected to double in 2030 and, with a share of 90%, fossil fuels will continue to dominate the energy system; (2) the great majority of the increase in oil production will come from OPEC countries and the EU will rely predominantly on natural gas imported from the CIS; and (3) as the largest growing energy demand and CO2 emissions originate from developing countries (mainly China and India), Europe will have to intensify its co-operation, particularly in terms of transfer of technologies. The analysis of long-term scenarios and a particular attention to the energy world context, is an important element for efficient energy, technology and environment policies towards a sustainable world

    2010-01-01

    This study analyses the outcome of the continuous improved occupant protection over the last two decades for front seat near side occupants in side impacts based on a real world driven working process. The effectiveness of four generations of improved side impact protection are calculated based on data from Volvo’s statistical accident database of Volvo Cars in Sweden. Generation I includes vehicles with a new structural and interior concept (SIPS). Generation II includes vehicles with structural improvements and a new chest airbag (SIPSbag). Generation III includes vehicles with further improved SIPS and SIPSbag as well as the new concept with a head protecting Inflatable Curtain (IC). Generation IV includes the most recent vehicles with further improvements of all the systems plus advanced sensors and seat belt pretensioner activation. Compared to baseline vehicles, vehicles of generation I reduce MAIS2+ injuries by 54%, generation II by 61% and generation III by 72%. For generation IV effectiveness figures cannot be calculated because of the lack of MAIS2+ injuries. A continuous improved performance is also seen when studying the AIS2+ pelvis, abdomen, chest and head injuries separately. By using the same real world driven working process, future improvements and possibly new passive as well as active safety systems, will be developed with the aim of further improved protection to near side occupants in side impacts.

    2002-03-01

    The world population grows rapidly: the number of mouths to feed increases. Is an agriculture without gene technology able to produce sufficiently in order to prevent hunger? Research indicates that hunger is not the result of short comings in agricultural outputs. It is however the result of poverty. This problem will not be solved by gene technology based agricultural production. This article explains the basic principles of mainstream and organic farming. Literature shows that the production potentials of both kinds of farming are, by far most, not yet exhausted. Gene technology is therefore unnecessary.

    A research dialectic between philosophy of technology and nurses' work in acute care surfaces parallel technological practices that threaten the healing nature of two modern projects: health care and ecological restoration. A metaphor of ecological restoration is used to explore the consequences of denatured health care work for the welfare of patients, families, practitioners, and healing communities. It is argued that in health care systems where the mismatch between treatment options and resources for care steadily grows, the nursing discipline must develop ecological literacy for a technological world.

    2010-01-01

    There have been aggressive developments in China on the technology of high intensity hadron accelerators for spallation neutron source, compact neutron source, accelerator driven sub-critical systems (ADS), and other related programs including hadron therapy. The primary challenge is to build a robust facility at a fraction of the 'world standard' cost. Benefiting from a close collaboration with world leading institutes and facilities, tremendous efforts were made in China to develop domestic vendors to comprehend the technology for key systems of high intensity ion source, linear accelerators, and rapid cycling synchrotron. Goals of such facilities include spallation-neutron-based, muon-based, and proton-based platforms for multi-discipline science and industrial applications, fast-neutron-based platform for nuclear science and applications, and parasitic apparatus for medical therapy and ADS tests. This paper attempts to summarize the R and D efforts, key component prototyping and vendor development experience, and user development efforts during the past several years in China. (author)

  8. The 1992 World Administrative Radio Conference: Technology and Policy Implications

    Science.gov (United States)

    1993-05-01

    As the 20th century draws to a close, new radio technologies and services are poised to change the ways we communicate. Radio waves already make possible a wide range of services considered commonplace--AM and FM radio broadcasting, television, cellular telephones, remote garage-door openers, and baby monitors. Advances in radio technology are giving birth to even more new products and services, including pocket-sized telephones that may allow people to make and receive calls anywhere in the world, high-definition televisions (HDTV) with superior quality pictures and sound, and static-free digital radios. The 1992 World Administrative Radio Conference (WARC-92) authorized frequencies for many of these new radio communication services, and granted additional frequencies for many existing services, including international broadcasting, satellite-based mobile communications, and communications in space. The effects of these changes will be felt well into the 21st century as countries around the world develop and deploy new communications systems to serve the needs of consumers, businesses, and governments. For the United States, the decisions made at the conference will critically affect how we develop new radio technologies and applications, how competitive this country will be in radio communications equipment and services, and how effectively the United States can exercise its role as a leader in world radio communication policymaking. This study of the outcomes and implications of WARC-92 was requested by the House Committee on Energy and Commerce and the Senate Committee on Commerce, Science, and Transportation. OTA was asked to evaluate the success of U.S. proposals at the conference, discuss the implications of the decisions made for U.S. technology and policy development, and identify options for improving U.S. participation in future world radio communication conferences.

  9. Driving and driven architectures of directed small-world human brain functional networks.

    Directory of Open Access Journals (Sweden)

    Chaogan Yan

    Full Text Available Recently, increasing attention has been focused on the investigation of the human brain connectome that describes the patterns of structural and functional connectivity networks of the human brain. Many studies of the human connectome have demonstrated that the brain network follows a small-world topology with an intrinsically cohesive modular structure and includes several network hubs in the medial parietal regions. However, most of these studies have only focused on undirected connections between regions in which the directions of information flow are not taken into account. How the brain regions causally influence each other and how the directed network of human brain is topologically organized remain largely unknown. Here, we applied linear multivariate Granger causality analysis (GCA and graph theoretical approaches to a resting-state functional MRI dataset with a large cohort of young healthy participants (n = 86 to explore connectivity patterns of the population-based whole-brain functional directed network. This directed brain network exhibited prominent small-world properties, which obviously improved previous results of functional MRI studies showing weak small-world properties in the directed brain networks in terms of a kernel-based GCA and individual analysis. This brain network also showed significant modular structures associated with 5 well known subsystems: fronto-parietal, visual, paralimbic/limbic, subcortical and primary systems. Importantly, we identified several driving hubs predominantly located in the components of the attentional network (e.g., the inferior frontal gyrus, supplementary motor area, insula and fusiform gyrus and several driven hubs predominantly located in the components of the default mode network (e.g., the precuneus, posterior cingulate gyrus, medial prefrontal cortex and inferior parietal lobule. Further split-half analyses indicated that our results were highly reproducible between two

    Low cost interval metering and communication technology improvements over the past ten years have enabled the maturity of load disaggregation (or non-intrusive load monitoring) technologies to better estimate and report energy consumption of individual end-use loads. With the appropriate performance characteristics, these technologies have the potential to enable many utility and customer facing applications such as billing transparency, itemized demand and energy consumption, appliance diagnostics, commissioning, energy efficiency savings verification, load shape research, and demand response measurement. However, there has been much skepticism concerning the ability of load disaggregation products to accurately identify and estimate energy consumption of end-uses; which has hindered wide-spread market adoption. A contributing factor is that common test methods and metrics are not available to evaluate performance without having to perform large scale field demonstrations and pilots, which can be costly when developing such products. Without common and cost-effective methods of evaluation, more developed disaggregation technologies will continue to be slow to market and potential users will remain uncertain about their capabilities. This paper reviews recent field studies and laboratory tests of disaggregation technologies. Several factors are identified that are important to consider in test protocols, so that the results reflect real world performance. Potential metrics are examined to highlight their effectiveness in quantifying disaggregation performance. This analysis is then used to suggest performance metrics that are meaningful and of value to potential users and that will enable researchers/developers to identify beneficial ways to improve their technologies.

    1995-01-01

    NASA Langley Research Center (LaRC) began using the World Wide Web (WWW) in the summer of 1993, becoming the first NASA installation to provide a Center-wide home page. This coincided with a reorganization of LaRC to provide a more concentrated focus on technology transfer to both aerospace and non-aerospace industry. Use of WWW and NCSA Mosaic not only provides automated information dissemination, but also allows for the implementation, evolution and integration of many technology transfer and technology awareness applications. This paper describes several of these innovative applications, including the on-line presentation of the entire Technology OPportunities Showcase (TOPS), an industrial partnering showcase that exists on the Web long after the actual 3-day event ended. The NASA Technical Report Server (NTRS) provides uniform access to many logically similar, yet physically distributed NASA report servers. WWW is also the foundation of the Langley Software Server (LSS), an experimental software distribution system which will distribute LaRC-developed software. In addition to the more formal technology distribution projects, WWW has been successful in connecting people with technologies and people with other people.

    Remote sensing education is increasingly in demand across academic and professional disciplines. Meanwhile, Internet technology and the World Wide Web (WWW) are being more frequently employed as teaching tools in remote sensing and other disciplines. The current wealth of information on the Internet and World Wide Web must be distilled, nonetheless, to be useful in remote sensing education. An extensive literature base is developing on the WWW as a tool in education and in teaching remote sensing. This literature reveals benefits and limitations of the WWW, and can guide its implementation. Among the most beneficial aspects of the Web are increased access to remote sensing expertise regardless of geographic location, increased access to current material, and access to extensive archives of satellite imagery and aerial photography. As with other teaching innovations, using the WWW/Internet may well mean more work, not less, for teachers, at least at the stage of early adoption. Also, information posted on Web sites is not always accurate. Development stages of this technology range from on-line posting of syllabi and lecture notes to on-line laboratory exercises and animated landscape flyovers and on-line image processing. The advantages of WWW/Internet technology may likely outweigh the costs of implementing it as a teaching tool.

    The serious economic crisis which rages since 2008 has been the result of a troubled era which started years before and contributed to aggravate the phenomenon. Energy crisis, biodiversity loss, global warming and its effects, markets deregulation have added up to economic recession. We are today the witnesses of a new deal of the cards illustrated by the social revolts of several Arab countries around the Mediterranean Sea. In this changing world, the declining occident cannot impose its economical or political leadership and the main emerging countries (Brazil, Russia, India, China and South Africa: BRICS) play a more and more important role. With 30% of population increase expected in 2050, the emerging countries represent the driver of the world growth and have become the keys of development questions. In front of this irreversible movement, urgent and worldwide changes have to be done. First of all, huge technological efforts and changes of the existing international institutions (IMF, UNO, WTO) and of their governance are necessary to build up a sustainable economy and energy policy with emerging countries. Such a transformation will be painful for the Occident as it will change its vision of growth based on political domination and search of financial wealth, energy and resources. It is this effort that the author aims to present in this book in a practical and visionary way, where technological progress occupies an important place

    TEK-Momentum is the Business Innovation and Technology Department in the Faculty of Engineering at the University of Southern Denmark in Odense. Since its establishment in 2010 the Department has adopted an exploratory technology transfer, open business development and co-creation strategy that goes beyond traditional technology transfer activities. This is an emerging strategy that has been shaped for the last 5 years even before the formal establishment of TEKMomentum. It emerged out of multiple dialog-based interactions with small- and medium-sized companies by focusing on matching real life problems with potential problem solvers. The main priority of such strategy is maximizing the value of the potential contributions from the multiple stakeholders and not on the technology development issues per se. In this paper we will present an overview of TEK-Momentum's approach by using as case studies two recent successful projects. The first one focuses on the commercialization of an LED illumination system. The second one focuses on the commercialization of an optical ring resonator-based temperature sensor.

    The title topic is discussed, and the activities of nuclides in the target gas system by 1 MW power after 6 months of work are tabulated. The following facts are stressed: Realization of traditional technology based mainly on cover gas replacement, release and feeding of gas mixtures into the loop is complicated and needs developing and applying devices for purification of the gases removed and radiation shielding of these devices at least. Such developments are especially urgent for ADS projects where coolant circulation is intensified by gas lift. Traditional technology is unable to solve a number of problems associated with the elimination of electropositive impurities (Au, Ag, Hg and others) that make a significant contribution to change compound and radio activity of ADS coolants. The task to remove such impurities was not set for traditional nuclear power plants, so that appropriate developments began only recently. New processes that could replace the developed processes have not been revealed in the course of investigations, however there is an opportunity of using new methods of their realization. For example, the processes of purification and regulation of coolant quality using chemically active gases can be implemented without using external gas systems. The solid hydride, metallooxide and other chemical compounds located in the gas volume or in the coolant loops of ADS can be the sources and absorbents of chemically active gas components. Applying to ADS conditions the emphasis of some processes goals can be slightly changed. For example: regulation of dissolved oxygen activity can be performed as well (probably, mainly) for oxygen refining of coolant by means of electronegative impurities transition into solid-phase oxide compounds; gas and coolant filtering can also be performed to localize radioactive impurities in the ADS circuit. Probably, the coolant technology can be employed to solve a number of tasks: to localize radioactive impurities in the

    We have developed an experimental World Wide Web (WWW) based system to deliver laboratory results to clinicians in our Veterinary Medical Teaching Hospital. Laboratory results are generated by the clinical pathology section of our Veterinary Medical Diagnostic Laboratory and stored in a legacy information system. This system does not interface directly to the hospital information system, and it cannot be accessed directly by clinicians. Our "meta" system first parses routine print reports and then instantiates the data into a modern, open-architecture relational database using a data model constructed with currently accepted international standards for data representation and communication. The system does not affect either of the existing legacy systems. Location-independent delivery of patient data is via a secure WWW based system which maximizes usability and allows "value-added" graphic representations. The data can be viewed with any web browser. Future extensibility and intra- and inter-institutional compatibility served as key design criteria. The system is in the process of being evaluated using accepted methods of assessment of information technologies.

    Enabling innovation and access to health technologies remains a key strategy in combating infectious diseases in low- and middle-income countries (LMICs). However, a gulf between paying markets and the endemicity of such diseases has contributed to the dearth of R&D in meeting these public health needs. While the pharmaceutical industry views emerging economies as potential new markets, most of the world's poorest bottom billion now reside in middle-income countries--a fact that has complicated tiered access arrangements. However, product development partnerships--particularly those involving academic institutions and small firms--find commercial opportunities in pursuing even neglected diseases; and a growing pharmaceutical sector in BRICS countries offers hope for an indigenous base of innovation. Such innovation will be shaped by 1) access to building blocks of knowledge; 2) strategic use of intellectual property and innovative financing to meet public health goals; 3) collaborative norms of open innovation; and 4) alternative business models, some with a double bottom line. Facing such resource constraints, LMICs are poised to develop a new, more resource-effective model of innovation that holds exciting promise in meeting the needs of global health.

    The project NATT, Neutron data for Accelerator-driven Transmutation Technology, is performed within the nuclear reactions group of the Department for neutron research, Uppsala university. The activities of the group is directed towards experimental studies of nuclear reaction probabilities of importance for various applications, like transmutation of nuclear waste, biomedical effects and electronics reliability. The experimental work is primarily undertaken at the The Svedberg Laboratory (TSL) in Uppsala, where the group has previously developed two world-unique instruments, MEDLEY and SCANDAL. Highlights from the past year: Analysis and documentation has been finalized of previously performed measurements of elastic neutron scattering from carbon and lead at 96 MeV. The precision in the results surpasses all previous data by at least an order of magnitude. These measurements represent the highest energy in neutron scattering where the ground state has been resolved. The results show that all previous theory work has underestimated the probability for neutron scattering at the present energy by 0-30 %. A new method for measurements of absolute probabilities for neutron-induced nuclear reactions with experimental techniques only has been developed. Previously, only two such methods have been known. One student has reached his PhD exam. Two PhD students have been accepted. TSL has decided to build a new neutron beam facility with significantly improved performance for these, and similar, activities. A new instrument for measurements of inelastic neutron scattering has been built, tested and found to meet the specifications. This work has been performed in collaboration with two French research groups from Caen and Nantes. The instrument is intended to be used for a series of experiments during the coming years. Previous work by the group on nuclear data for assessment of electronics reliability has lead to a new industry standard in the USA.

    Advances in medicine have improved health and healthcare for many around the world. The challenge is achieving the best outcomes of health via healthcare delivery to every individual. Healthcare inequalities exist within a country and between countries. Health information technology (HIT) has provided a mean to deliver equal access to healthcare services regardless of social context and physical location. In order to achieve better health outcomes for every individual, socio-cultural factors, such as literacy and social context need to consider. This paper argues that HIT while improves healthcare inequalities by providing access, might worsen healthcare inequity. In order to improve healthcare inequity using HIT, this paper argues that we need to consider patients and context, and hence the concept of context driven care. To improve healthcare inequity, we need to conceptually consider the patient's view and methodologically consider design methods that achieve participatory outcomes.

    Caregiving for a person with dementia can lead to physical and psychological morbidity. Technology-driven interventions hold the promise of convenient, low-cost methods of delivering psychosocial interventions. This systematic review examined the efficacy of technology-driven interventions for caregivers of persons with dementia. A search of Ovid Medline, PsychInfo, and EBSCO from 1990 to May 2012 resulted in the identification of 295 articles. After removal of duplicates, 271 articles were reviewed, based on the abstract and title alone; 32 were relevant or could not be fully assessed without assessing the entire article. Eight fully satisfied the inclusion/exclusion criteria. Each of these had some positive findings. However, there was large variability in the content and delivery of the interventions and inconsistency in measurement and variability of outcomes. Future studies should employ randomized control trial methodology and measure outcomes with commonly used measures to ensure feasibility of comparisons across the studies.

    Food irradiation is an efficient technology that can be used to ensure food safety by eliminating insects and pathogens to prolong the shelf life. The process could be applied to fresh or frozen products without affecting the nutritional value. Presently more than 60 countries have adopted the technology. However, the technology adaptation differs from one country to another and, in some cases, consumers' misunderstanding and lack of acceptance may hinder the technology adaptation process. This review summarizes the development of irradiation treatment worldwide and consumer attitudes towards the introduction of this technology. Also, the wholesomeness, beneficial effects, and regulation of irradiation are assessed.

    2015-03-01

    Physics students graduate from their course of studies to enter the ``world of work.'' While for many years that transition meant joining a large corporation for a life-long career, this is no longer the case. Today's graduates will find their career with a series of organizations - often start-ups and small to mid-sized organizations - whose future depends on the ability to rapidly leverage technical knowledge into useful products and services. This session will discuss the value of preparing physics students to be innovators and entrepreneurs, both as a strategy to prepare them for future careers, as well as an opportunity to fully engage students in seeing the relevance of physics to ``real world'' challenges. The session will feature three case studies: 1) embedding core knowledge and skills within a technical content course; 2) building learning experiences around a team-based start-up exploration; 3) engaging an entire department in considering how to comprehensively include innovation & entrepreneurship themes in the curriculum. The session will conclude with information about how faculty members and institutions can access resources for adopting this approach to their course offerings.

    What were utilization, outcomes and practices in assisted reproductive technology (ART) globally in 2008, 2009 and 2010? Global utilization and effectiveness remained relatively constant despite marked variations among countries, while the rate of single and frozen embryo transfers (FETs) increased with a concomitant slight reduction in multiple birth rates. ART is widely practised in all regions of the world. Monitoring utilization, an approximation of availability and access, as well as effectiveness and safety is an important component of universal access to reproductive health. This is a retrospective, cross-sectional survey on utilization, effectiveness and safety of ART procedures performed globally from 2008 to 2010. Between 58 and 61 countries submitted data from a total of nearly 2500 ART clinics each year. Aggregate country data were processed and analyzed based on forms and methods developed by the International Committee for Monitoring Assisted Reproductive Technologies (ICMART). Results are presented at country, regional and global level. For the years 2008, 2009 and 2010, >4 461 309 ART cycles were initiated, resulting in an estimated 1 144 858 babies born. The number of aspirations increased by 6.4% between 2008 and 2010, while FET cycles increased by 27.6%. Globally, ART utilization remained relatively constant at 436 cycles/million in 2008 and 474 cycles/million population in 2010, but with a wide country range of 8-4775 cycles/million population. ICSI remained constant at around 66% of non-donor aspiration cycles. The IVF/ICSI combined delivery rate (DR) per fresh aspiration was 19.8% in 2008; 19.7% in 2009 and 20.0% in 2010, with corresponding DRs for FET of 18.8, 19.7 and 20.7%. In fresh non-donor cycles, single embryo transfer increased from 25.7% in 2008 to 30.0% in 2010, while the average number of embryos transferred fell from 2.1 to 1.9, again with wide regional variation.

    International Nuclear Information System (INIS)

    Lee, S.

    1987-01-01

    A program to initiate experimental plasma physics in developing countries has been started as a definite step for technology sharing. Cost effectiveness of several devices has been carefully considered from the viewpoint of physical mechanisms and existing technology. From this consideration emerges the plasma focus which whilst requiring no extraordinary technology yet could be packaged into a comprehensive facility for training in plasma production, plasma dynamics, plasma diagnostic and measurement of plasma x-rays, REB and fusion neutrons, with a very wide scope for the establishment of indigeneous training and research. It is shown that the simplicity of the approach is no barrier to the richness of plasma phenomena. Indeed the simplicity allows a clear comparison of pinch devices and, for example, enables two crucial limitations of existing plasma focus devices to be singled out, the overcoming of which could result in a many-fold jump in neutron yield. Hence the need for basic studies of these limitations. These and other studies could just as well be made on small devices. The UNU Training Programme resulted from the above consideration and evolved around the UNU/ICTP PFF, a small plasma focus with interesting physics and cost-effective technology. The extension of future training programmes to cover other important devices, for example, of the FRC type such as the Rotamak could widen the scope of this sharing of plasma and fusion technology.

    In this paper, photonic devices driven by surface acoustic waves and operating in the GHz frequency range are presented. The devices were designed and fabricated in (Al,Ga)As technology. In contrast to previously realized modulators, where part of the light transmission is lost due to destructive interference, in the present devices light only switches paths, avoiding losses. One of the devices presents two output channels with 180°-dephasing synchronization. Odd multiples of the fundamental driving frequency are enabled by adjusting the applied acoustic power. A second and more complex photonic integrated device, based on the acoustic modulation of tunable Arrayed Waveguide Gratings, is also proposed.

The challenge facing most companies is not whether to adopt Service-Oriented Architecture (SOA, but when and how to do so. There is always a lag between technological vision and business feasibility. It also takes time to fully realize the potential of existing technologies, a process that does not stop the moment the new thing arrives. But when the value of a new approach such as ESA starts to make a difference and produces a competitive advantage, the motivation to change skyrockets. The time to change becomes now and the hunger for learning grows. The goal of this paper is to satisfy the hunger for information for those who suspect that ESA may be a gateway to transforming Information Technology (IT into a strategic weapon. This paper will explain – in more detail that ever before – what ESA is bringing the concept to life in all of its products as a platform supported by an ecosystem.

  14. Reserve growth during financial volatility in a technologically challenging world

    Science.gov (United States)

    Klett, Timothy R.; Gautier, Donald L.

    2010-01-01

    Reserve growth (growth-to-known) is the addition of oil and gas quantities to reported proved or proved-plus-probable reserves in discovered fields. The amount of reserve growth fluctuates through time with prevailing economic and technological conditions. Most reserve additions are the result of investment in field operations and in development technology. These investments can be justified by higher prices of oil and gas, the desire to maintain cash flow, and by greater recovery efficiency in well established fields. The price/cost ratio affects decisions for field abandonment and (or) implementation of improved recovery methods. Although small- to medium-size fields might show higher percentages of reserve growth, a relatively few giant fields contribute most volumetric reserve growth, indicating that companies may prefer to invest in existing fields with low geologic and production risk and an established infrastructure in order to increase their price/cost relationship. Whereas many previous estimates of reserve growth were based on past trends of reported reserves, future reserve growth is expected to be greatly affected by financial volatility and fluctuating economic and technological conditions.

  15. Accelerator-driven transmutation technology: a high-tech solution to some nuclear waste problems

    International Nuclear Information System (INIS)

    Hechanova, A.E.

    2001-01-01

    This paper discusses current technical and non-technical issues regarding the innovative concept of using accelerator-driven transmutation processes for nuclear waste management. Two complex and related issues are addressed. First, the evolution of the current U.S. conceptual design is identified to indicate that there has been sufficient technological advancement with regard to a 1991 scientific peer review to warrant the advent of a large-scale national research and development program. Second, the economics and politics of the transmutation system are examined to identify non-technical barriers to the implementation of the program. Although a number of key challenges are identified in this paper, the benefits of the research and development effort and the potential paradigm shift in attitude toward resource stewardship could greatly enhance public confidence in nuclear waste management that will have rapid positive repercussions on nuclear technology research and commercial applications.

    Directory of Open Access Journals (Sweden)

    A. Unwin

    2007-09-01

    Full Text Available Higher Education (HE professionals generally work in an ICT rich environment. There are expectations that the existence of ICT benefits them, their students and the overall learning environment. These assumptions are often left unchallenged due to a lack of developed theoretical frameworks. This paper introduces and critiques the TPCK framework by reviewing the origins of the concepts used in its formulation and by experimenting with the model in the context of a HE course. Although the TPCK framework raises and focuses the debate about technologies in education this paper suggests some key issues are potentially missing. The paper suggests that pedagogic design needs a clear focus on the role of the learner in the process and that HE requires collaborative communities of practice that include ICT ‘enthusiasts’ within any course team. The paper suggests these are key factors in enhancing the capacity of the HE staff to engage positively, collaboratively and critically with the growth of learning technologies and in turn design appropriate and successful online components within their courses.

    Simulation-based education has evolved as a key training tool in high-risk industries such as aviation and the military. In parallel with these industries, the benefits of incorporating specialty-oriented simulation training within medical schools are vast. Adoption of simulators into medical school education programs has shown great promise and has the potential to revolutionize modern undergraduate education. An English literature search was carried out using MEDLINE, EMBASE, and psychINFO databases to identify all randomized controlled studies pertaining to "technology-driven" simulators used in undergraduate medical education. A validity framework incorporating the "framework for technology enhanced learning" report by the Department of Health, United Kingdom, was used to evaluate the capabilities of each technology-driven simulator. Information was collected regarding the simulator type, characteristics, and brand name. Where possible, we extracted information from the studies on the simulators' performance with respect to validity status, reliability, feasibility, education impact, acceptability, and cost effectiveness. We identified 19 studies, analyzing simulators for medical students across a variety of procedure-based specialities including; cardiovascular (n = 2), endoscopy (n = 3), laparoscopic surgery (n = 8), vascular access (n = 2), ophthalmology (n = 1), obstetrics and gynecology (n = 1), anesthesia (n = 1), and pediatrics (n = 1). Incorporation of simulators has so far been on an institutional level; no national or international trends have yet emerged. Simulators are capable of providing a highly educational and realistic experience for the medical students within a variety of speciality-oriented teaching sessions. Further research is needed to establish how best to incorporate simulators into a more primary stage of medical education; preclinical and clinical undergraduate medicine.

    Full text: Radiation processing is based on application of gamma industrial sources and electron accelerators. Recently development of high power accelerators made a operation mode of e/X as a viable tool for these applications as well. Included in this are service type facilities operated in Research and Development centers. When other uses are taken into account, there are in total over 300 gamma irradiators being operated for a variety of purposes in 55 different countries. 100-120 gamma irradiators are located in Europe and in the United States. Recent developments in very high current accelerators show considerable promise for the industrial use of X rays as a future technology of choice. X ray comparable in penetration to gamma rays. The use of high energy X rays for sterilizing medical devices was proposed during the 1960th, but not implemented until the late 1990th. X-rays are comparable in penetration to gamma emissions from radioactive isotopes, but being electrically sourced can be turned on or off not posing the storage, supply and transport issues associated with the use of isotopes. The development of nana-composites, which is only a few years old, is very promising. This includes the development of nano-gels. This nano-gels can be used for drug or vaccine delivery and are especially suited for the delivery of anti-cancer agents into tumor tissues. The use of natural polymers and fibers is another growing area in the use of radiation processing. Radiation processing is also being used to enhance befoul manufacture. Food the hygenization is other important application of radiation processing and finally environmental applications are still challenging field or radiation use.

  5. Important requirements for RF generators for Accelerator-Driven Transmutation Technologies (ADTT)

    All Accelerator-Driven Transmutation applications require very large amounts of RF Power. For example, one version of a Plutonium burning system requires an 800-MeV, 80-mA, proton accelerator running at 100% duty factor. This accelerator requires approximately 110-MW of continuous RF power if one assumes only 10% reserve power for control of the accelerator fields. In fact, to minimize beam spill, the RF controls may need as much as 15 to 20% of reserve power. In addition, unlike an electron accelerator in which the beam is relativistic, a failed RF station can disturb the synchronism of the beam, possibly shutting down the entire accelerator. These issues and more lead to a set of requirements for the RF generators which are stringent, and in some cases, conflicting. In this paper, we will describe the issues and requirements, and outline a plan for RF generator development to meet the needs of the Accelerator-Driven Transmutation Technologies. The key issues which will be discussed include: operating efficiency, operating linearity, effect on the input power grid, bandwidth, gain, reliability, operating voltage, and operating current

    During the mid-20th century motorized equipment replaced work animals in the central U.S. This led to a 95% decrease in farmland for producing oats, which had mostly been used as feed for horses. Much of this land was converted to more profitable crops such as soybeans and maize. The same period also saw a strong shift of the central U.S. precipitation intensity spectrum toward heavier events. Was this a coincidence, or is there a causal relationship? We investigate possible connections between this technology-driven land use change and regional hydroclimate by performing multi-decadal simulations over the central U.S. using the WRF-ARW regional climate model coupled with the Community Land Model (CLM 4.5). Cropland planted in maize, soybean, winter wheat, small grains (which includes oats and spring wheat), and other C3 and C4 crops were reconstructed on a decade by decade basis from 1940-2010 using county-level crop data. These crop distributions were used as land surface boundary conditions for two multi-decadal regional climate simulations, one with 1940s land use and another with modern (circa 2010) land use. Modern land use produced a shift in the simulated daily precipitation intensity spectrum toward heavy events, with higher frequencies of heavy precipitation amounts and lower frequencies of light amounts compared to 1940s land use. The results suggest that replacement of work animals by mechanized transport led to land use changes that produced about 10-30% of the observed trend toward more intense precipitation over the central United States. We therefore recommend that policy- and technology-driven changes in crop type be taken into account when projecting future climate and water resources.

    The Accelerator-Driven Transmutation Technology (ADTT) Project carries three approaches for dealing with waste from the defense and commercial nuclear energy enterprise. First, the problem of excess weapons plutonium in the U.S. and Russia originating both from stockpile reductions and from defense production site clean-up is one of significant current and long-term concern. The ADTT technology offers the possibility of almost complete destruction of this plutonium by fission. The technology might be particularly effective for destruction of the low quality plutonium from defense site clean-up since the system does not require the fabrication of the waste into fuel assemblies, does not require reprocessing and refabrication, and can tolerate a high level of impurities in the feed stream. Second, the ADTT system also can destroy the plutonium, other higher actinide, and long-lived fission product from commercial nuclear waste which now can only be dealt with by geologic storage. And finally, and probably most importantly the system can be used for the production of virtually unlimited electric power from thorium with concurrent destruction of its long-lived waste components so that geologic containment for them is not required. In addition plutonium is not a significant byproduct of the power generation so that non-proliferation concerns about nuclear power are almost completely eliminated. All of the ADTT systems operate with an accelerator supplementing the neutrons which in reactors are provided only by the fission process, and therefore the system can be designed to eliminate the possibility for a runaway chain reaction. The means for integration of the accelerator into nuclear power technology in order to make these benefits possible is described including estimates of accelerator operating parameters required for the three objectives.

    2015-12-01

    Innovative training in 'Sustainable Agriculture' for an increasingly STEM-dependent agricultural sector will require a combination of approaches and technologies for global agricultural production to increase while offsetting climate change. Climate change impacts the water resources of nations as normal global weather patterns are altered during El Nino events. Agricultural curricula must incorporate awareness of 'climate change' in order to find novel ways to (1) assure global food security; (2) improve soil productivity and conservation; (3) improve crop yields and irrigation; (4) inexpensively develop site specific principles of crop management based on variable soil and associated hydrological properties; and (5) improve precision farming. In February 2015, Central State University (CSU), Ohio became an 1890 Land-Grant institution vital to the sustainability of Ohio's agricultural sector. Besides agricultural extension, the agriculture curriculum at CSU integrates multidisciplinary courses in science, technology engineering, agriculture, and mathematics (STEAM). The agriculture program could benefit from a technology-driven, interdisciplinary soil science course that promotes climate change education and climate literacy while being offered in both a blended and collaborative learning environment. The course will focus on the dynamics of microscale to mesoscale processes occurring in farming systems, those of which impact climate change or could be impacted by climate change. Elements of this course will include: climate change webinars; soil-climate interactions; carbon cycling; the balance of carbon fluxes between soil storage and atmosphere; microorganisms and soil carbon storage; paleoclimate and soil forming processes; geophysical techniques used in the characterization of soil horizons; impact of climate change on soil fertility; experiments; and demonstrations.

    Full Text Available The current rapid technological changes confront researchers of learning technologies with the challenge of evaluating them, predicting trends, and improving their adoption and diffusion. This study utilizes a data-driven discourse analysis approach, namely culturomics, to investigate changes over time in the research of learning technologies. The patterns and changes were examined on a corpus of articles published over the past decade (2006-2014 in the proceedings of Chais Conference for the Study of Innovation and Learning Technologies – the leading research conference on learning technologies in Israel. The interesting findings of the exhaustive process of analyzing all the words in the corpus were that the most commonly used terms (e.g., pupil, teacher, student and the most commonly used phrases (e.g., face-to-face in the field of learning technologies reflect a pedagogical rather than a technological aspect of learning technologies. The study also demonstrates two cases of change over time in prominent themes, such as “Facebook” and “the National Information and Communication Technology (ICT program”. Methodologically, this research demonstrates the effectiveness of a data-driven approach for identifying discourse trends over time.

    Getting the right data when it is needed continues to be a challenge for researchers and decision makers. Event-Driven Data Delivery (ED3), funded by the NASA Applied Science program, is a technology that allows researchers and decision makers to pre-plan what data, information and processes they need to have collected or executed in response to future events. The Information Technology and Systems Center at the University of Alabama in Huntsville (UAH) has developed the ED3 framework in collaboration with atmospheric scientists at UAH, scientists at the Geological Survey of Alabama, and other federal, state and local stakeholders to meet the data preparedness needs for research, decisions and situational awareness. The ED3 framework supports an API that supports the addition of loosely-coupled, distributed event handlers and data processes. This approach allows the easy addition of new events and data processes so the system can scale to support virtually any type of event or data process. Using ED3's underlying services, applications have been developed that monitor for alerts of registered event types and automatically triggers subscriptions that match new events, providing users with a living "album" of results that can continued to be curated as more information for an event becomes available. This capability can allow users to improve capacity for the collection, creation and use of data and real-time processes (data access, model execution, product generation, sensor tasking, social media filtering, etc), in response to disaster (and other) events by preparing in advance for data and information needs for future events. This presentation will provide an update on the ED3 developments and deployments, and further explain the applicability for utilizing near-realtime data in hazards research, response and situational awareness.

    2015-08-01

    Full Text Available The business value of information technology (IT services is often difficult to assess, especially from the point of view of a non-IT manager. This condition could severely impact organizational IT strategic decisions. Various approaches have been proposed to quantify the business value, but some are trapped in technical complexity while others misguide managers into directly and subjectively judging some technical entities outside their domain of expertise. This paper describes a method on how to properly capture both perspectives based on a  probabilistic business-driven model. The proposed model presents a procedure to calculate the business value of IT services. The model also covers IT security services and their business value as an important aspect of IT services that is not covered in previously published researches. The impact of changes in the quality of IT services on business value will also be discussed. A simulation and a case illustration are provided to show the possible application of the proposed model for a simple business process in an enterprise.

    A beamline systems code, that is being developed for Accelerator-Driven Transmutation Technology (ADTT) facility trade studies, is described. The overall program is a joint Grumman, G.H. Gillespie Associates (GHGA) and Los Alamos National Laboratory effort. The GHGA Accelerator Systems Model (ASM) has been adopted as the framework on which this effort is based. Relevant accelerator and beam transport models from earlier Grumman systems codes are being adapted to this framework. Preliminary physics and engineering models for each ADTT beamline component have been constructed. Examples noted include a Bridge Coupled Drift Tube Linac (BCDTL) and the accelerator thermal system. A decision has been made to confine the ASM framework principally to beamline modeling, while detailed target/blanket, balance-of-plant and facility costing analysis will be performed externally. An interfacing external balance-of-plant and facility costing model, which will permit the performance of iterative facility trade studies, is under separate development. An ABC (Accelerator Based Conversion) example is used to highlight the present models and capabilities.

    Technologies have become a major force in people's lives. They change how people interact with the environment, even as the environment changes. We propose that technology use in the setting of changing environments is motivated by essential needs and tensions experienced by the individual. We apply three developmental and behavioral theories (Erikson's stages of psychosocial development, Maslow's hierarchy of needs, and Bronfenbrenner's ecological model) to explain technology-related behaviors among older adults. We consider how technology use has addressed and can address major ecological changes, in three areas: health promotion, natural disasters, and disparities. We propose that considering these theories can help researchers and developers ensure that technologies will help promote a healthier world for older adults. © The Author(s) 2015.

  8. Electromechanically driven microchopper for integration in microspectrometers based on LIGA technology

    1999-09-01

    In recent years, microspectrometers made by the LIGA technology for the visible wavelength range have found their way into the market. Opening the wide field of spectral analysis in the infrared range, the concept of a highly transmissive hollow waveguide has been demonstrated successfully. In combination with linear detector arrays, hollow waveguide microspectrometers can be combined into handheld infrared spectrometer systems. The only obstacle to a miniaturized system is the lack of miniaturized light modulators. To solve this problem, a miniaturized light modulator has been developed. It consists of an oscillating stop driven by an electromagnetic actuator. It is made out of permalloy by means of LIGA micromechanics. Its outer dimensions of approx. 3.0 X 3.2 mm2 and a structure height of 280 micrometer allow it to be integrated into the plane of the entrance slit of the microspectrometer of about 20 mm to 30 mm size. The spectrometer has alignment structures to ensure positioning of the oscillating stop close to the entrance slit. This simplifies assembly. The actuator is excited by an hybrid integrated coil fixed by springs snapping into place during assembly. The maximum supply voltage of 5V allows the chopper to be used in low-voltage spectrometer systems, especially in handheld systems. The highest modulation frequency is more than 1 kHz, which is sufficient to work with the lead salt detectors commonly used. In this frequency range, detector noise is greatly attenuated compared to continuous-light operation. The paper contains an outline of the concept of the whole microspectrometer system. Experimental results are discussed to demonstrate the performance of the system.

Because they are designed to show the best possible results, typically Phase III studies are conducted under ideal and highly controlled conditions. Consequently, it is not surprising that technologies do not always perform in real life in the same way as controlled conditions. Because financing (and price paid) decisions can be made with overestimated results, health authorities need to ask whether health systems achieve the results they expect when they choose to pay for a technology. The optimal way to answer this question is to assess the performance of financed technologies in real-world settings. Health technology performance assessment (HTpA) refers to the systematic evaluation of the properties, effects, and/or impact of a health intervention or health technology in the real world to provide information for investment/disinvestment decisions and clinical guideline updates. The objective is to describe the development and principal aspects of the Guideline for HTpA commissioned by the Brazilian Ministry of Health. Our methods used include extensive literature review, refinement with experts across countries, and public consultation. A comprehensive guideline was developed, which has been adopted by the Brazilian government. We believe the guideline, with its particular focus on disinvestment, along with the creation of a specific program for HTpA, will allow the institutionalization and continuous improvement of the scientific methods to use real-world evidence to optimize available resources not only in Brazil but across countries.

  10. A demographic projection of the contribution of assisted reproductive technologies to world population growth.

    Enormous unmet needs for infertility treatment exist because access to assisted reproductive technologies is demographically skewed. Since the first IVF baby in 1978, the number of people conceived by reproductive technology has grown much faster than expected, reaching several million today and rapidly approaching 0.1% of the total world population. As more patients build families, and their children in turn become parents, the number owing their existence to assisted reproductive technologies, either directly or indirectly, will expand tremendously in future decades, but no attempts have been made hitherto to project the magnitude. We have projected growth to the year 2100, along with the fractional contribution to world population. The chief variable driving growth is access to fertility services. If it stagnates at current levels of about 400,000 babies per year, an estimated 157 million people alive at the end of the century will owe their lives to assisted reproductive technologies (1.4% of global population), but at an arbitrary upper limit of 30,000 extra births annually there will be 394 million additional people alive (3.5%). As the conquest of infertility continues, individuals who owe their lives to assisted reproductive technologies will quietly make a significant contribution to demographic growth as well as social progress.

  11. Constructing Worlds: Reflections on Science, Technology and Democracy (and a Plea for Bold Modesty

    Directory of Open Access Journals (Sweden)

    2017-05-01

    Full Text Available Can STS offer a response to “alternative facts” without falling back into naive positivism? Can STS help to make science accountable to society and make it work—make it function in our democracies and let it produce scientific knowledge? In his valedictory lecture, Wiebe Bijker looks back upon three decades of STS research in general, and upon engaging STS with questions of democratization and development in particular. He starts from the question how to study technological cultures and ends with the question how to construct them. The argument moves from the social construction of technology to constructing socio-technical worlds. Finally, when trying to understand this construction work, the analysis zooms in on the constructing worlds: on the institutions in which this construction work takes place.

    Embedded Systems have traditionally been developed in a highly customized manner. The user interface hardware and software along with the interface to the embedded system are typically unique to the system for which they are built, resulting in extra cost to the system in terms of development time and maintenance effort. World Wide Web standards have been developed in the passed ten years with the goal of allowing servers and clients to intemperate seamlessly. The client and server systems can consist of differing hardware and software platforms but the World Wide Web standards allow them to interface without knowing about the details of system at the other end of the interface. Embedded Web Technology is the merging of Embedded Systems with the World Wide Web. Embedded Web Technology decreases the cost of developing and maintaining the user interface by allowing the user to interface to the embedded system through a web browser running on a standard personal computer. Embedded Web Technology can also be used to simplify an Embedded System's internal network.

    Natural forests store vast amounts of carbon in the terrestrial biosphere, and play an important role in the global carbon cycle. Given the significance of natural forests, there is a lack of carbon accounting of primary forests that are undisturbed by human activities. One reason for this lack of interest stems from ecological orthodoxy that suggests that primary forests should be close to dynamic equilibrium, in that Net Ecosystem Production (NEP) approaches zero. However, recent results from the northern hemisphere and tropics, using eddy covariance flux towers, indicate that primary forests are a greater sink than first thought. The role of evergreen primary forests in Australian carbon balance studies remain uncertain and hence may function differently to their deciduous counterparts in the Northern Hemisphere. In order to address the lack of baseline carbon accounts, an undisturbed, 300 year old Mountain Ash (Eucalyptus regnans) ecosystem, located in the Central Highlands of Victoria (Australia) was selected as a permanent study site to investigate carbon and water budgets over diurnal, seasonal and annual cycles. Mountain Ash trees are the world's tallest angiosperms (flowering plants), and one of the largest carbon reservoirs in the biosphere, with an estimated 1900 tC ha-1. A 110 m tall micrometeorological tower that includes eddy covariance instrumentation was installed in August 2005. An independent biometric approach quantifying the annual net gain or loss of carbon was also made within close proximity to the flux tower. Analysis of NEP in 2006 suggests that the ecosystem acted as a carbon sink of 2.5 tC ha-1 yr-1. Woody and soil biomass increment for the same year was estimated to be 2.8 tC ha-1yr-1, in which nearly half of the biomass production was partitioned into the aboveground woody tissue. These results indicate that temperate primary forests act as carbon sinks, and are able to maintain their carbon sink status due to their uneven stand

  15. Mimewrighting: Preparing Students for the Real World of Science, Technology, Engineering, and Math

    Shope, R. E.

    2013-12-01

    READING, WRITING, & ENACTING SCIENTIFIC & TECHNICAL LITERATURE: Mimewrighting applies the art of mime as an interpretive springboard to integrate conceptual understanding across all content areas. Mimewrighting guides students to read and express complex ideas in carefully crafted movement integrations, mediating experience, so that students obtain an intuitive grasp of difficult and abstract ideas. THE PROBLEM: Reading science writing presents obstacles for middle and high school students, to the point that many students are turned OFF to science altogether. A typical science abstract, written for colleagues, is as densely packed with concept-laden words as a black hole is densely packed with matter- and just as mysterious. What reads to a science colleague as a richly crafted paragraph, from which a myriad of elegantly interrelated concepts can unfold to point to the significance and context of the study at hand, reads as jabberwocky nonsense to the uninitiated student. So, how do we turn such kids (and teachers) back ON to the inquiry-driven desire to seek out challenging and educative experiences? How do we step up to the national challenge to prepare ALL students adequately for the REAL-WORLD demands of science, technology, engineering, math, (STEM) and communications? How do we help kids read, write, and understand scientific and technical literature? AN UNCONVENTIONAL ANSWER: Mimewrighting applies the classic art of mime to unpack the meaning of science writing. We help students view the text as sequences of action, scenarios that can be enacted theatrically for understanding. HOW DOES IT WORK? READ ALOUD, MIME ALONG: It's as simple as read aloud and mime along. And as complex, in that it requires taking the time to acknowledge each concept packed into the passage. Three opening sentences might involve twenty minutes of mimewrighting activity to ensure that students apprehend the patterns, perceive the relationships, and comprehend the dynamics of such a

    To analyze information on assisted reproductive technology (ART) performed worldwide and trends in outcomes over successive years. Cross-sectional survey on access, effectiveness, and safety of ART procedures performed in 53 countries during 2005. A total of 2,973 clinics from national and regional ART registries. Infertile women and men undergoing ART globally. Collection and analysis of international ART data. Number of cycles performed by country and region, including pregnancies, single and multiple birth rates, and perinatal mortality. Overall, 1,052,363 ART procedures resulted in an estimated 237,315 babies born. The availability of ART varied by country from 15 to 3,982 cycles per million of population. Of all initiated fresh cycles, 62.9% were intracytoplasmic sperm injection. The overall delivery rate per fresh aspiration was 19.6% and for frozen embryo transfer 17.4%, with a cumulative delivery rate of 23.9%. With wide regional variations, single embryo transfer represented 17.5% of cycles, and the proportion of deliveries with twins and triplets from fresh transfers was 23.6% and 1.5%, respectively. Systematic collection and dissemination of international ART data allows patients, health professionals, and policy makers to examine and compare the impact of reproductive strategies or lack of them as markers of reproductive health.

    Animal breeding and reproductive physiology have been closely related throughout the history of animal production science. Artificial insemination provides the best method of increasing the influence of sires with superior genetics to improve production traits. Multiple ovulation embryo transfer (MOET) provides some ability to increase the genetic influence of the maternal line as well. The addition of genetic technologies to this paradigm allows for improved methods of selecting sires and dams carrying the best genes for production and yield of edible products and resistance to diseases and parasites. However, decreasing the number of influential parents within a population also increases the risk of propagating a recessive gene that could negatively impact the species (Reprod Domest Anim 44:792-796, 2009; BMC Genomics 11:337, 2010). Furthermore, antagonistic genotypic relationships between production traits and fertility (Anim Prod Sci 49:399-412, 2009; Anim Genet 43:442-446, 2012) suggest that care must be taken to ensure that increasing the frequency of genes with a positive influence on production does not negatively impact the fertility of the replacement females entering the herd.

    At present, medical applications applying World Wide Web (WWW) technology are mainly used to view static images and to retrieve some information. The Java platform is a relative new way of computing, especially designed for network computing and distributed applications which enables interactive connection between user and information via the WWW. The Java 2 Software Development Kit (SDK) including Java2D API, Java Remote Method Invocation (RMI) technology, Object Serialization and the Java Advanced Imaging (JAI) extension was used to achieve a robust, platform independent and network centric solution. Medical image processing software based on this technology is presented and adequate performance capability of Java is demonstrated by an iterative reconstruction algorithm for single photon emission computerized tomography (SPECT).

Cross-sectional survey on access, efficiency, and safety of ART procedures performed in 55 countries during 2007. Not applicable. Infertile women and men undergoing ART globally. Collection and analysis of international ART data. Number of cycles performed, by country and region, including pregnancies, single and multiple birth rates, and perinatal mortality. Overall, >1,251,881 procedures with ART were reported, and resulted in 229,442 reported babies born. The availability of ART varied by country, from 12 to 4,140 treatments per million population. Of all aspiration cycles, 65.2% (400,617 of 614,540) were intracytoplasmic sperm injection. The overall delivery rate per fresh aspiration was 20.3%, and for frozen-embryo transfer (FET), 18.4%, with a cumulative delivery rate of 25.8%. With wide regional variations, single-embryo transfer represented 23.4% of fresh transfers, and the proportion of deliveries with twins and triplets from fresh transfers was 22.3% and 1.2%, respectively. The perinatal mortality rate was 19.9 per 1,000 births for fresh in vitro fertilization using intracytoplasmic sperm injection, and 9.6 per 1,000 for FET. The proportion of women aged ≥40 years increased to 19.8% from 15.5% in 2006. The international trend toward women aged >40 years was a major component of ART services in some regions and countries.

  20. Mobilizing science and technology to address the problems of the world's poor

    International Nuclear Information System (INIS)

    Sachs, J.

    2001-01-01

    Full text: Writing in The Economist of 15 February this year, Prof. Sachs raised several points that are relevant to any discussion of technical co-operation for sustainable development. He urges a stronger emphasis on the transfer of appropriate technology, and supports expanded roles for United Nations organizations in helping to solve the problems of the world's poorest countries. Here are some excerpts: 'A(n)...important challenge, as yet mainly unrecognised, is that of mobilising global science and technology to address the crises of public health, agricultural productivity, environmental degradation and demographic stress confronting these countries (i.e., the 42 so-called Highly Indebted Poor Countries - HIPCs, ed.) In part this will require that the wealthy governments enable the grossly underfinanced and underempowered United Nations institutions to become vibrant and active partners of human development.' The conditions in many HIPCs are worsening dramatically, even as global science and technology create new surges of wealth and well-being in richer countries. The problem is that, for myriad reasons, the technological gains in wealthy countries do not readily diffuse to the poorest ones....Research and development of new technologies are overwhelmingly directed at rich-country problems. To the extent that the poor face distinctive challenges, science and technology must be directed purposefully towards them (emphasis added). In today's global set-up, that rarely happens....Currently, the international system fails to meet the technological needs of the world's poorest.' Prof. Sachs has been one of the few development economists to consistently remind us that most of the world's poor live under vastly different environmental conditions - mainly tropical climates with their often unique disease agents and agricultural factors - than most of the rich. He points out that sustainable development is not possible unless the underlying ecological constraints are

    2014-10-01

    Full Text Available Of the numerous projects that involve ICTs to solve the problems of the developing world, many are unsuccessful. Reasons include lack of attention to how the human and social systems need to adapt to the new technologies, problems with the intent of the initiators, and lack of user involvement. Focusing on the design of ICT for education and acknowledging the range of complex reasons for possible failure, this article focuses on lack on involvement of end users (specifically children in the design and development of ICT solutions. Children in the developing world are not given voice when it comes to the design of technology aimed at providing them with better education. Through examination of the concept of “children’s voice” as well as through discussion of a practical design case to support underprivileged children in South Africa, this article shows that (1 listening to children requires that adult co-designers have the correct attitude towards their child partners and that they are committed to really hearing them; (2 power relations and context plays an important role in the contribution children can make; and (3 South African children have the ability to provide essential input into the design of technology for education.

  2. An implicit world view in technology and its consequences for contemporary life.

    Science.gov (United States)

    Ketner, K L

    1996-01-01

    To summarize, when the technological way of thinking is taken to the extreme it becomes a world view that is associated with a particular danger, in that it is not taken by its proponents as one of many competing world views but is considered uncritically to be a fact, not a hypothesis. Through a series of applications of the fallacy of hypothesis/fact confusion and through uncritical use of the technological frame of mind, one can inevitably become committed to an overarching physicalism, materialism, mechanicalism, and determinism, perhaps without even knowing that one has such afflictions. My own discipline, philosophy, which I regard as a science in the broad sense previously mentioned, has not escaped being captured by this technological mind-set, much to its detriment. I refer readers who are interested in the plight of philosophy in this age to the works of Hilary Putnam, Bruce Wilshire, Ludwig Wittgenstein, or Charles Peirce. I take this step because I am not a machine, and if I didn't stop now, I would feel guilty about taking too much of your time.

    2001-08-01

    Modern civilisation explores and penetrates the interior of the Earth's crust, recovers from it and stores into it solids, fluids and gases to a hitherto unprecedented degree. Management of underground structures such as boreholes or reservoirs take into account the existing stress either to take advantage of it or at least to minimise the effects of man-made stress. This paper presents the World Map of Tectonic Stresses (in short: World Stress Map or WSM) as a fundamental geophysical data-base. The impact of the WSM is pointed out: in the context of global tectonics, in seismic hazard quantification and in a wide range of technological problems in industrial applications such as oil reservoir management and stability of underground openings (tunnels, boreholes and waste disposal sites).

    Full Text Available Middlebury Interactive Language (MIL programs are designed to teach world language courses using blended and online learning for students in kindergarten through grade 12. Middlebury Interactive courses start with fundamental building blocks in four key areas of world-language study: listening comprehension, speaking, reading, and writing. As students progress through the course levels, they deepen their understanding of the target language, continuing to focus on the three modes of communication: interpretive, interpersonal, and presentational. The extensive use of authentic materials (video, audio, images, or texts is intended to provide a contextualized and interactive presentation of the vocabulary and the linguistic structures. In the present paper, we describe the MIL program and the results of a mixed-methods survey and case-study evaluation of its implementation in a broad sample of schools. Technology application is examined with regard to MIL instructional strategies and the present evaluation approach relative to those employed in the literature.

    This report summarizes the organization, activities, and outcomes of Student Pugwash USA`s 1992 International Conference, Visions for a Sustainable World: A Conference on Science, Technology and Social Responsibility. The conference was held June 14--20, 1992 at Emory University, and brought together 94 students and over 65 experts from industry, academe, and government. The conference addressed issues ranging from global environmental cooperation to the social impacts of the Human Genome Project to minority concerns in the sciences. It provided a valuable forum for talented students and professionals to engage in critical dialogue on many interdisciplinary issues at the juncture of science, technology and society. The conference challenged students -- the world`s future scientists, engineers, and political leaders -- to think broadly about global problems and to devise policy options that are viable and innovative. The success of the conference in stimulating interest, understanding, and enthusiasm about interdisciplinary global issues is clearly evident from both the participants` feedback and their continued involvement in Student Pugwash USA programs. Six working groups met each morning. The working group themes included: environmental challenges for developing countries; energy options: their social and environmental impact; health care in developing countries; changing dynamics of peace and global security; educating for the socially responsible use of technology; ethics and the use of genetic information. The conference was specifically designed to include mechanisms for ensuring its long-term impact. Participants were encouraged to focus on their individual role in helping resolve global issues. This was achieved through each participant`s development of a Personal Plan of Action, a plan which mapped out activities the student could undertake after the conference to continue the dialogue and work towards the resolution of global and local problems.

    Centralized wastewater management system is the modern day waste management practice, but the high cost and stringent requirements for the construction and operation have made it less attractive in the under-resourced regions of the world. Considering these challenges, the use of decentralized wastewater management system, on-site treatment system, as an appropriate technology for domestic wastewater treatment is hereby advocated. Adopting this technology helps save money, protects home owners' investment, promotes better watershed management, offers an appropriate solution for low-density communities, provides suitable alternatives for varying site conditions and furnishes effective solutions for ecologically sensitive areas. In the light of this, an overview of the on-site treatment scheme, at the laboratory scale, pilot study stage, and field trials was conducted to highlight the operational principles' strength and shortcomings of the scheme. The operational requirements for the establishing and operation of the scheme and best management practice to enhance the performance and sustenance were proffered.

    Recent developments in Internet technologies are changing and enhancing how one processes and exchanges information. These developments include software and hardware in support of multimedia applications on the World Wide Web. In this paper the authors describe these technologies as they have applied them to remote monitoring and show how they will allow the International Atomic Energy Agency to efficiently review and analyze remote monitoring data for verification of material movements. The authors have developed demonstration software that illustrates several safeguards data systems using the resources of the Internet and Web to access and review data. This Web demo allows the user to directly observe sensor data, to analyze simulated safeguards data, and to view simulated on-line inventory data. Future activities include addressing the technical and security issues associated with using the Web to interface with existing and planned monitoring systems at nuclear facilities. Some of these issues are authentication, encryption, transmission of large quantities of data, and data compression.

    The world is food secure at the global level, yet nearly 800 million are food insecure. "Business as usual" is not going to bring us close to meeting the Millennium Development Goal of halving the proportion of the population consuming less than the minimum energy requirement. So what has to change? The three papers in this session offer clues in three broad areas: (a) increased investment-by developing and developed countries-in public goods such as agricultural research, education, and clean water, (b) technologies to boost agricultural productivity for the poor and institutions that guide the diffusion and application of technology that need to be developed and (c) national-level institutions and governance structures to be strengthened and held accountable for protecting and respecting human rights, for providing the right types of national-level public goods to those that most need them and for preserving peace and stability.

    In this article, we discuss robotic-assisted therapy as an emerging and significant field of clinical rehabilitation and its value proposition for innovating rehabilitation clinical practice. Attempts to achieve integration among clinicians' practices and bioengineers' machines often generate new challenges and controversies. To date, the literature is indicative of a sizeable number and variety of robotic devices in the field of clinical rehabilitation, some are commercially available; however, large-scale clinical outcomes are less positive than expected. The following main themes related to integrating rehabilitation technology in real-world clinical practice will be discussed: the application of current evidence-based practice and knowledge in relation to treatment in the rehabilitation clinic, perspectives from rehabilitation professionals using robotic-aided therapy with regard to challenges, and strategies for problem solving. Lastly, we present innovation philosophies with regard to sustainability of clinical rehabilitation technologies.

    Convergence of knowledge and technology for the benefit of society (CKTS) is the core opportunity for progress in the twenty-first century. CKTS is defined as the escalating and transformative interactions among seemingly different disciplines, technologies, communities, and domains of human activity to achieve mutual compatibility, synergism, and integration, and through this process to create added value and branch out to meet shared goals. Convergence has been progressing by stages over the past several decades, beginning with nanotechnology for the material world, followed by convergence of nanotechnology, biotechnology, information, and cognitive science (NBIC) for emerging technologies. CKTS is the third level of convergence. It suggests a general process to advance creativity, innovation, and societal progress based on five general purpose principles: (1) the interdependence of all components of nature and society, (2) decision analysis for research, development, and applications based on dynamic system-logic deduction, (3) enhancement of creativity and innovation through evolutionary processes of convergence that combines existing principles and divergence that generates new ones, (4) the utility of higher-level cross-domain languages to generate new solutions and support transfer of new knowledge, and (5) the value of vision-inspired basic research embodied in grand challenges. CKTS is a general purpose approach in knowledge society. It allows society to answer questions and resolve problems that isolated capabilities cannot, as well as to create new competencies, knowledge, and technologies on this basis. Possible solutions are outlined for key societal challenges in the next decade, including support for foundational emerging technologies NBIC to penetrate essential platforms of human activity and create new industries and jobs, improve lifelong wellness and human potential, achieve personalized and integrated healthcare and education, and secure a

    Despite the tremendous improvements in conventional desalination technologies, its wide use is still limited due primarily to high energy requirements which are currently met with expensive fossil fuels. The use of alternative energy sources is essential to meet the growing demand for water desalination. In the last few decades a lot of effort has being directed in the use of different renewable energy (RE) sources to run desalination processes. However, the expansion of these efforts towards larger scale plants is hampered by several techno-economic challenges. Several medium-scale RE-driven desalination plants have been installed worldwide. Nevertheless, most of these plants are connected to the electrical grid to assure a continuous energy supply for stable operation. Furthermore, RE is mostly used to produce electric power which can be used to run desalination systems. This review paper focuses on an integrated approach in using RE-driven with an emphasis on solar and geothermal desalination technologies. Innovative and sustainable desalination processes which are suitable for integrated RE systems are presented. An assessment of the benefits of these technologies and their limitations are also discussed.

    Concerns about mitigating and adapting to climate change resulted in renewing the incentive for agricultural research investments and developing further innovation priorities around the world particularly in developing countries. In the near future, development of new agricultural measures and proper diffusion of technologies will greatly influence the ability of farmers in adaptation and mitigation to climate change. Using bibliometric approaches through output of academic journal publications and patent-based data, we assess the impact of research and development (R&D) for new and existing technologies within the context of climate change mitigation and adaptation. We show that many developing countries invest limited resources for R&D in relevant technologies that have great potential for mitigation and adaption in agricultural production. We also discuss constraints including weak infrastructure, limited research capacity, lack of credit facilities and technology transfer that may hinder the application of innovation in tackling the challenges of climate change. A range of policy measures is also suggested to overcome identified constraints and to ensure that potentials of innovation for climate change mitigation and adaptation are realized.

    1994-01-01

    NASA Langley Research Center (LaRC) began using the World Wide Web (WWW) in the summer of 1993, becoming the first NASA installation to provide a Center-wide home page. This coincided with a reorganization of LaRC to provide a more concentrated focus on technology transfer to both aerospace and non-aerospace industry. Use of the WWW and NCSA Mosaic not only provides automated information dissemination, but also allows for the implementation, evolution and integration of many technology transfer applications. This paper describes several of these innovative applications, including the on-line presentation of the entire Technology Opportunities Showcase (TOPS), an industrial partnering showcase that exists on the Web long after the actual 3-day event ended. During its first year on the Web, LaRC also developed several WWW-based information repositories. The Langley Technical Report Server (LTRS), a technical paper delivery system with integrated searching and retrieval, has proved to be quite popular. The NASA Technical Report Server (NTRS), an outgrowth of LTRS, provides uniform access to many logically similar, yet physically distributed NASA report servers. WWW is also the foundation of the Langley Software Server (LSS), an experimental software distribution system which will distribute LaRC-developed software with the possible phase-out of NASA's COSMIC program. In addition to the more formal technology distribution projects, WWW has been successful in connecting people with technologies and people with other people. With the completion of the LaRC reorganization, the Technology Applications Group, charged with interfacing with non-aerospace companies, opened for business with a popular home page.

    What do Remotely Operated Vehicles (ROVs), Ocean Science, Engineering and Technology have in common with science education in today's classroom? They all meet the growing demand for science, technology, engineering, and mathematics (STEM) professionals in tomorrow's U.S. workforce. Engaging students in real world science experiences will help them develop skills such as critical thinking, problem solving, collaboration, communication, innovation, and creativity. These skills are crucial to building a strong, competitive workforce in an integrated global economy. Fifth grade students from St. Andrew's School of Math and Science in Charleston, SC, USA science classes were introduced to engineering and robotics by using a combination of two underwater ROVs programs from the Office of Naval Research (SeaPerch) and Marine Advanced Technology Education (MATE). Students were grouped in teams as "real scientists" to design and construct a ROV. Students selected their role from a list of engineering positions, and researched how to construct the best ROV. Students created blueprints and models of their ROV design. Scientists/engineers from various local agencies were scheduled to come and share their expertise with the students. On World Ocean Day, a presentation was planned for fifth grade students to work closely with kindergarten through fourth grade students. The purpose of the day was two-fold; it provided students the opportunity to peer teach and the opportunity to present their experiences to a wide audience. All students presented their designs and demonstrated their ROV's movement capabilities in child size pools. They also modeled how submersible pilots communicate with scientists and other researchers while operating their newly designed ROV. As a culminating event, students visited a local marine science high school class with similar ROVs and evaluated their engineering designs in a fresh water pond.

  3. True North: Building Imaginary Worlds with the Revised Canadian (CADTH Guidelines for Health Technology Assessment

    Directory of Open Access Journals (Sweden)

    2017-05-01

    Full Text Available In March 2017 the Canadian Agency for Drugs and Technologies in Health (CADTH released the 4th edition of their Guidelines for the Economic Evaluation of Health Technologies: Canada. These guidelines, which were first published and revised for a 3rd edition in 2006 are intended to help decision makers, health systems leaders and policy makers make well-informed decisions. They are designed, apparently, to support best practice in conducting health technology assessments in Canada. The purpose of this commentary is to consider whether or not the evidence standards proposed and the consequent modeled claims for economic effectiveness meet the standards of normal science: are the CADTH standards capable of generating claims for competing products that are credible, evaluable and replicable? The review argues that the standards proposed by CADTH do not meet the standards expected in normal science. Technical sophistication in building reference case imaginary worlds is not a substitute for claims that are experimentally evaluable or capable of assessment through systematic observation. There is no way of judging whether imaginary claims are right or even if they are wrong. CADTH is not alone in setting standards that fail to meet the standards of normal science. Recent commentaries on formulary submission guidelines in a number of other countries, to include Ireland, the Netherlands, France, Australia, the UK and New Zealand conclude that they are subject to the same criticism. If the CADTH guidelines were never intended to support feedback to health system decision makers, then this should be made clear. If not, then consideration should be given to withdrawing the guidelines to ensure they conform to these standards. Hopefully, future versions of the CADTH guidelines will address this issue and focus on a rigorous research program of claims assessment and feedback and not the building of imaginary worlds.   Type:  Commentary

    Full Text Available Modern technology (internet, smartphones, etc. already has an impact on communication and health care services throughout the world. Evidently, everyone knows what it means to be able to better communicate with new technology (such as Facebook, Twitter, LinkedIn etc.. The problem is not here. It is evident that science advances quickly and turns peoples’ lives upside down, even if these advances have never had much of an impact on social, cultural, and psychological dimensions of the individual, the family, and the social group. At what point, then, do these advances in science have an impact for us, the mental health professionals? We will soon find ourselves in a situation where we will be obliged to accept the new methods of communication being presented to us, not only by policy makers, but also by patients and their families. Therefore, we must look at how we both have been integrating the advances of Information Technology into social psychiatry, but also how we can do so in the future.

    Digital technologies, especially if used in novel ways, provide a number of potential advantages to clinical research in trials related to human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) and may greatly facilitate operations as well as data collection and analysis. These technologies may even allow answering questions that are not answerable with older technologies. However, they come with a variety of potential concerns for both the participants and the trial sponsors. The exact challenges and means for alleviation depend on the technology and on the population in which it is deployed, and the rapidly changing landscape of digital technologies presents a challenge for creating future-proof guidelines for technology application. The aim of this study was to identify and summarize some common themes that are frequently encountered by researchers in this context and highlight those that should be carefully considered before making a decision to include these technologies in their research. In April 2016, the Global HIV Vaccine Enterprise surveyed the field for research groups with recent experience in novel applications of digital technologies in HIV clinical research and convened these groups for a 1-day meeting. Real-world uses of various technologies were presented and discussed by 46 attendees, most of whom were researchers involved in the design and conduct of clinical trials of biomedical HIV prevention and treatment approaches. After the meeting, a small group of organizers reviewed the presentations and feedback obtained during the meeting and categorized various lessons-learned to identify common themes. A group of 9 experts developed a draft summary of the findings that was circulated via email to all 46 attendees for review. Taking into account the feedback received, the group finalized the considerations that are presented here. Meeting presenters and attendees discussed the many successful applications of digital

    2018-01-29

    We analyze use of an interactive system for the exploration of highly detailed three-dimensional (3D) models of a collection of protostoric Mediterranean sculptures. In this system, when the object of interest is selected, its detailed 3D model and associated information are presented at high resolution on a large display controlled by a touch-enabled horizontal surface at a suitable distance. The user interface combines an object-Aware interactive camera controller with an interactive point-ofinterest selector and is implemented within a scalable implementation based on multiresolution structures shared between the rendering and user interaction subsystems. The system was installed in several temporary and permanent exhibitions and was extensively used by tens of thousands of visitors. We provide a data-driven analysis of usage experience based on logs gathered during a 27-month period at four exhibitions in archeological museums for a total of more than 75K exploration sessions. We focus on discerning the main visitor behaviors during 3D exploration by employing tools for deriving interest measures on surfaces and tools for clustering and knowledge discovery from high-dimensional data. The results highlight the main trends in visitor behavior during the interactive sessions. These results provide useful insights for the design of 3D exploration user interfaces in future digital installations.© 2017 ACM 1556-4673/2017/12-ART2 $15.00.

    2007-07-01

    Various international dynamics are converging to increase the attractiveness of decentralized energy as a complement to existing centralized energy infrastructures. Decentralized energy (DE) technologies, including onsite renewables, high efficiency cogeneration and industrial energy recycling, offer considerable benefits to those seeking working alternatives to emerging challenges in the energy sector. DE is ideally suited to provide clean affordable energy to areas where modern energy services are currently lacking. Having smaller generators close to where energy is required ensures a safe, reliable and secure energy supply when the energy is required. Furthermore, because DE is a much cleaner alternative than conventional central power plants and the energy provided comes at a much smaller price tag DE is an increasingly acceptable alternative both in the developed and developing world. DE is sure to play a key role in any plan to build a sustainable energy future. (auth)

    Canada produces about one third of the world's uranium mine output, most of it from two new mines. After 2007 Canadian production is expected to increase further as more new mines come into production. About 15% of Canada's electricity comes from nuclear power, using indigenous technology, and 18 reactors provide over 12,500 MWe of power. Mexico has two nuclear reactors generating almost 5% of its electricity. Its first commercial nuclear power reactor began operating in 1989. There is some government support for expanding nuclear energy to reduce reliance on natural gas. Argentina has two nuclear reactors generating nearly one tenth of its electricity. Its first commercial nuclear power reactor began operating in 1974. Brazil has two nuclear reactors generating 4% of its electricity. Its first commercial nuclear power reactor began operating in 1982.

  13. Research to practice in addiction treatment: key terms and a field-driven model of technology transfer.

    Science.gov (United States)

    2011-09-01

    The transfer of new technologies (e.g., evidence-based practices) into substance abuse treatment organizations often occurs long after they have been developed and shown to be effective. Transfer is slowed, in part, due to a lack of clear understanding about all that is needed to achieve full implementation of these technologies. Such misunderstanding is exacerbated by inconsistent terminology and overlapping models of an innovation, including its development and validation, dissemination to the public, and implementation or use in the field. For this reason, a workgroup of the Addiction Technology Transfer Center (ATTC) Network developed a field-driven conceptual model of the innovation process that more precisely defines relevant terms and concepts and integrates them into a comprehensive taxonomy. The proposed definitions and conceptual framework will allow for improved understanding and consensus regarding the distinct meaning and conceptual relationships between dimensions of the technology transfer process and accelerate the use of evidence-based practices.

    2017-07-06

    This patient perspective piece presents an important case at the intersection of mobile health technology, mental health, and innovation. The potential of digital technologies to advance mental health is well known, although the challenges are being increasingly recognized. Making mobile health work for mental health will require broad collaborations. We already know that those who experience mental illness are excited by the potential technology, with many actively engaged in research, fundraising, advocacy, and entrepreneurial ventures. But we don't always hear their voice as often as others. There is a clear advantage for their voice to be heard: so we can all learn from their experiences at the direct intersection of mental health and technology innovation. The case is cowritten with an individual with schizophrenia, who openly shares his name and personal experience with mental health technology in order to educate and inspire others. This paper is the first in JMIR Mental Health's patient perspective series, and we welcome future contributions from those with lived experience. ©John Torous, Spencer Roux.

  15. A market-driven commercialization strategy for gasification-based technologies

    International Nuclear Information System (INIS)

    Klara, J.M.; Tomer, B.J.; Stiegel, G.J.

    1998-01-01

    In the wake of deregulation of power generation in the US, market-based competition is driving electricity generators to low-cost risk system. In such an environment, gasification-based technologies will not be competitive with low capital cost, efficient, and reliable natural gas-fired facilities for baseload power generation in the foreseeable future. The lack of a near-term market application poses a serious threat to the progress of gasification technology. With a reduction in direct federal funding of large-scale demonstration plants as the trend to reduce the size of government continues, an alternate approach to commercialize gasification-based technologies has been developed at DOE/FETC. This new strategy employs gasification in near-term markets where, due to its ability to coproduce a wide variety of commodity and premium products to meet market requirements, it is an attractive alternative. By obtaining operating experience in near-term coproduction applications, gasification system modules can be refined and improved leading to commercial guarantees and acceptance of gasification technology as a cost-effective technology for baseload power generation when this market begins to open domestically, sometime after 2005

    As the demographics of many countries shift towards an ageing population it is predicted that the prevalence of diseases affecting cognitive capabilities will continually increase. One approach to enabling individuals with cognitive decline to remain in their own homes is through the use of cognitive prosthetics such as reminding technology. However, the benefit of such technologies is intuitively predicated upon their successful adoption and subsequent use. Within this paper we present a knowledge-based feature set which may be utilized to predict technology adoption amongst Persons with Dementia (PwD). The chosen feature set is readily obtainable during a clinical visit, is based upon real data and grounded in established research. We present results demonstrating 86% accuracy in successfully predicting adopters/non-adopters amongst PwD.

  17. Driven to extinction? The ethics of eradicating mosquitoes with gene-drive technologies.

    Science.gov (United States)

    Pugh, Jonathan

    2016-09-01

    Mosquito-borne diseases represent a significant global disease burden, and recent outbreaks of such diseases have led to calls to reduce mosquito populations. Furthermore, advances in 'gene-drive' technology have raised the prospect of eradicating certain species of mosquito via genetic modification. This technology has attracted a great deal of media attention, and the idea of using gene-drive technology to eradicate mosquitoes has been met with criticism in the public domain. In this paper, I shall dispel two moral objections that have been raised in the public domain against the use of gene-drive technologies to eradicate mosquitoes. The first objection invokes the concept of the 'sanctity of life' in order to claim that we should not drive an animal to extinction. In response, I follow Peter Singer in raising doubts about general appeals to the sanctity of life, and argue that neither individual mosquitoes nor mosquitoes species considered holistically are appropriately described as bearing a significant degree of moral status. The second objection claims that seeking to eradicate mosquitoes amounts to displaying unacceptable degrees of hubris. Although I argue that this objection also fails, I conclude by claiming that it raises the important point that we need to acquire more empirical data about, inter alia, the likely effects of mosquito eradication on the ecosystem, and the likelihood of gene-drive technology successfully eradicating the intended mosquito species, in order to adequately inform our moral analysis of gene-drive technologies in this context.

  18. HAS Should Not Be NICE: Rejecting Imaginary Worlds in the French Technology Assessment Guidelines

    Directory of Open Access Journals (Sweden)

    Paul C Langley

    2017-01-01

    Full Text Available Pricing decisions and access to pharmaceuticals should be evidence based. Unfortunately, the French guidelines for technology assessment, in their adoption of the National Institute for Health and Clinical Excellence (NICE reference case modeling standard ensure that this is not the case. Rather than requiring the submission of claims that are credible, evaluable and replicable, the Haute Autorité de Sante (HAS mandates the creation of imaginary worlds to support comparative effectiveness and cost-outcome claims. The purpose of this commentary is to make the case that HAS should reconsider this commitment to standards for health technology assessment that are more appropriately seen as pseudoscience. The recommendation is that HAS should put to one side mandating lifetime cost-per-quality adjusted life year (QALY or life years saved claims in favor of short-term claims that can be evaluated and reported to health system decision makers as part of a provisional assessment of new products as well as supporting ongoing disease area and therapeutic class reviews.   Type: Commentary

    New, visually rich, astronomical software environments coupled with large web-accessible data sets hold the promise of new and exciting ways to teach, collaborate, and explore the universe. These freeware tools provide contextual views of astronomical objects, real time access to multi-wavelength sky surveys, and, most importantly, the ability to incorporate new data and to produce user created content. This interactive panel examined the capabilities of Google Sky and WorldWide Telescope, and explored case studies of how these tools have been used to create compelling and participatory educational experiences in both formal (i.e., K-12 and undergraduate non-science majors classrooms), and informal (e.g., museum) settings. The overall goal of this session was to stimulate a discussion about future uses of these technologies. Substantial time was allotted for participants to create conceptual designs of learning experiences for use at their home institutions, with feedback provided by the panel members. Activities included technical discussions (e.g., mechanisms for incorporating new data and dissemination tools), exercises in narrative preparation, and a brainstorming session to identify potential future uses of these technologies.

    Information about drivers' experiences with driver assistance technologies in real driving conditions is sparse. This study characterized driver interactions with forward collision warning, adaptive cruise control, active lane keeping, side-view assist, and lane departure warning systems following real-world use. Fifty-four Insurance Institute for Highway Safety employees participated and drove a 2016 Toyota Prius, 2016 Honda Civic, 2017 Audi Q7, or 2016 Infiniti QX60 for up to several weeks. Participants reported mileage and warnings from the technologies in an online daily-use survey. Participants reported their level of agreement with five statements regarding trust in an online post-use survey. Responses were averaged to create a composite measure of trust ranging from -2 (strongly disagree) to +2 (strongly agree) for each technology. Mixed-effect regression models were constructed to compare trust among technologies and separately among the study vehicles. Participants' free-response answers about what they liked least about each system were coded and examined. Participants reported driving 33,584 miles during 4 months of data collection. At least one forward collision warning was reported in 26% of the 354 daily reports. The proportion of daily reports indicating a forward collision warning was much larger for the Honda (70%) than for the Audi (18%), Infiniti (15%), and Toyota (10%). Trust was highest for side-view assist (0.98) and lowest for active lane keeping (0.20). Trust in side-view assist was significantly higher than trust in active lane keeping and lane departure warning (0.53). Trust in active lane keeping was significantly lower than trust in adaptive cruise control (0.67) and forward collision warning (0.71). Trust in adaptive cruise control was higher for the Audi (0.72) and Toyota (0.75) compared with the Honda (0.30), and significantly higher for the Infiniti (0.93). Trust in Infiniti's side-view assist (0.58) was significantly lower than

  1. On Singularities and Black Holes in Combination-Driven Models of Technological Innovation Networks.

    Solé, Ricard; Amor, Daniel R; Valverde, Sergi

    2016-01-01

    It has been suggested that innovations occur mainly by combination: the more inventions accumulate, the higher the probability that new inventions are obtained from previous designs. Additionally, it has been conjectured that the combinatorial nature of innovations naturally leads to a singularity: at some finite time, the number of innovations should diverge. Although these ideas are certainly appealing, no general models have been yet developed to test the conditions under which combinatorial technology should become explosive. Here we present a generalised model of technological evolution that takes into account two major properties: the number of previous technologies needed to create a novel one and how rapidly technology ages. Two different models of combinatorial growth are considered, involving different forms of ageing. When long-range memory is used and thus old inventions are available for novel innovations, singularities can emerge under some conditions with two phases separated by a critical boundary. If the ageing has a characteristic time scale, it is shown that no singularities will be observed. Instead, a "black hole" of old innovations appears and expands in time, making the rate of invention creation slow down into a linear regime.

  3. On Singularities and Black Holes in Combination-Driven Models of Technological Innovation Networks.

    Directory of Open Access Journals (Sweden)

    Ricard Solé

    Full Text Available It has been suggested that innovations occur mainly by combination: the more inventions accumulate, the higher the probability that new inventions are obtained from previous designs. Additionally, it has been conjectured that the combinatorial nature of innovations naturally leads to a singularity: at some finite time, the number of innovations should diverge. Although these ideas are certainly appealing, no general models have been yet developed to test the conditions under which combinatorial technology should become explosive. Here we present a generalised model of technological evolution that takes into account two major properties: the number of previous technologies needed to create a novel one and how rapidly technology ages. Two different models of combinatorial growth are considered, involving different forms of ageing. When long-range memory is used and thus old inventions are available for novel innovations, singularities can emerge under some conditions with two phases separated by a critical boundary. If the ageing has a characteristic time scale, it is shown that no singularities will be observed. Instead, a "black hole" of old innovations appears and expands in time, making the rate of invention creation slow down into a linear regime.

    Machine learning in healthcare, and innovative healthcare technology in general, require complex interactions within multidisciplinary teams. Healthcare hackathons are being increasingly used as a model for cross-disciplinary collaboration and learning. The aim of this study is to explore high school student learning experiences during a healthcare hackathon. By optimizing their learning experiences, we hope to prepare a future workforce that can bridge technical and health fields and work seamlessly across disciplines. A qualitative exploratory study utilizing focus group interviews was conducted. Eight high school students from the hackathon were invited to participate in this study through convenience sampling Participating students (n = 8) were allocated into three focus groups. Semi structured interviews were completed, and transcripts evaluated using inductive thematic analysis. Through the structured analysis of focus group transcripts three major themes emerged from the data: (1) Collaboration, (2) Transferable knowledge and skills, and (3) Expectations about hackathons. These themes highlight strengths and potential barriers when bringing this multidisciplinary approach to high school students and the healthcare community. This study found that students were empowered by the interdisciplinary experience during a hackathon and felt that the knowledge and skills gained could be applied in real world settings. However, addressing student expectations of hackathons prior to the event is an area for improvement. These findings have implications for future hackathons and can spur further research into using the hackathon model as an educational experience for learners of all ages.

    The Southeastern (SE) Minnesota Beacon organized all the health care providers, county public health organizations, and school districts in the deployment and integration of health information exchange (HIE) and targeted health communication around childhood asthma and diabetes. The community cooperated to establish a clinical data repository for all residents in the 11-county region. Through this community of practice approach that involved traditional and nontraditional providers, the SE Minnesota Beacon was able to realize unique applications of this technology. This manuscript overviews the associated organization and infrastructure of this community collaboration. The Office of the National Coordinator for Health Information Technology (ONC), as part of the American Recovery and Reinvestment Act of 2009 (ARRA) stimulus, established 17 projects throughout the United States targeting the introduction and meaningful use of health information technology (HIT). These 17 communities were intended to serve as an example of what could be accomplished. The SE Minnesota Beacon is one of these communities. The community ultimately opted for peer-to-peer HIE, using Nationwide Health Information Network (NwHIN) Connect software. The clinical data repository was established using the infrastructure developed by the Regenstrief Institute, which operated as a trusted third party. As an extension to HIE, the consortium of county public health departments created a patient data portal for use by school nurses and parents. Childhood asthma was addressed by creating, exchanging, and maintaining an "asthma action plan" for each affected child, shared throughout the community, including through the patient portal. Diabetes management introduced patient treatment decision tools and patient quality of life measures, facilitating care. Influenza vaccination was enhanced by large-scale community reporting in partnership with the state vaccination registry. The methodology and

    The objective of this study is to help establish the long-range nuclear waste disposal strategy through the investigations and comparisons of various= concepts of the accelerator-driven nuclear waste transmutation reactors, which have been suggested to replace the geological waste disposal due to the technical uncertainties in the long-time scale. Nuclear data, categorized in high -and low-energy neutron cross-sections, were investigated and the structures, principles, and recent progresses of proton linac were reviews, Also the accelerator power for transmutation and the economics were referred, The comparison of the transmutation concepts concentrated on two: Japanese OMEGA program of alloy fuelled system, Minor actinide molten salt system, and Eutectic alloy system and American ATW program of aqueous system and molten salt system. From the comparative study, a state-of-art of the technology has been identified as a concept employing proton-accelerate of 800 {approx} 1600 MeV with 100 mA capacity combined with liquid lead target, molten salt blanket and on-line chemical separation using centrifuge and electrowinning technology. 34 refs., 25 tabs., 64 figs.

  1. Going beyond best technology and lowest price: on renewable energy investors’ preference for service-driven business models

    International Nuclear Information System (INIS)

    Loock, Moritz

    2012-01-01

    Renewable energy is becoming increasingly important for economies in many countries. But still in an emerging industry, renewable energy requires supportive energy policy helping firms to develop and protect competitive advantages in global competition. As a guideline for designing such policy, we consult well-informed stakeholders within the renewable energy industry: investors. Their preferences serve as explorative indicator for assessing which business models might succeed in competition. To contribute to only limited research on renewable energy investors’ preferences, we ask, which business models investment managers for renewable energy prefer to invest in. We report from an explorative study of 380 choices of renewable energy investment managers. Based on the stated preferences, we modelled three generic business models to calculate the share of investors’ preferences. We find exiting evidence: a “customer intimacy” business model that proposes best services is much more preferred by investors than business models that propose lowest price or best technology. Policy-makers can use those insights for designing policy that supports service-driven business models for renewable energy with a scope on customer needs rather than technology or price. Additionally, we state important implications for renewable energy entrepreneurs, managers and research.

    2000-09-01

    This report is based largely on presentations and discussions at two workshops and contributions from workshop participants. The workshop on Fundamental Challenges in Electron-Driven Chemistry was held in Berkeley, October 9-10, 1998, and addressed questions regarding theory, computation, and simulation. The workshop on Electron-Driven Processes: Scientific Challenges and Technological Opportunities was held at Stevens Institute of Technology, March 16-17, 2000, and focused largely on experiments. Electron-molecule and electron-atom collisions initiate and drive almost all the relevant chemical processes associated with radiation chemistry, environmental chemistry, stability of waste repositories, plasma-enhanced chemical vapor deposition, plasma processing of materials for microelectronic devices and other applications, and novel light sources for research purposes (e.g. excimer lamps in the extreme ultraviolet) and in everyday lighting applications. The life sciences are a rapidly advancing field where the important role of electron-driven processes is only now beginning to be recognized. Many of the applications of electron-initiated chemical processes require results in the near term. A large-scale, multidisciplinary and collaborative effort should be mounted to solve these problems in a timely way so that their solution will have the needed impact on the urgent questions of understanding the physico-chemical processes initiated and driven by electron interactions.

    Hong Y. Park

    2015-12-01

    Full Text Available User knowledge has been an important source of novel product development and innovation, but gathering accurate user knowledge has been time consuming and difficult because user knowledge is tacit and globally dispersed. However, information and communication technology can expand the boundaries by making user knowledge easier and less expensive to access. Structures and organizations are emerging to perform the task of user information gathering. This paper examines the nature of user knowledge and the emergence of a new system/structure for user knowledge gathering and user involvement in innovation. Three case studies of business innovation in three different organizations illustrate the ways that the organization matches the type of innovation with the characteristics of user knowledge. User involvement can occur either through direct input or via feedback provided after customers received services. User input can also be either proactive or reactive. User knowledge is often employed to monitor service workers also, which has significantly contributed to recent improvement in service quality. The cases presented support our proposition.

    Large observational implementation studies are needed to triangulate the findings from randomized control trials (RCTs) as they reflect "real world" everyday practice. In a pilot study, we attempted to provide additional and complementary insights on the real life treatment of allergic rhinitis using mobile technology. A mobile phone app (Allergy Diary, freely available Google Play and Apple App stores) collects the data of daily visual analogue scales (VAS) for (i) overall allergic symptoms, (ii) nasal, ocular and asthma symptoms, (iii) work, as well as (iv) medication use using a treatment scroll list including all medications (prescribed and over the counter (OTC)) for rhinitis customized for 15 countries. A total of 2,871 users filled in 17,091 days of VAS in 2015 and 2016. Medications were reported for 9,634 days. The assessment of days appeared to be more informative than the course of the treatment as, in real life, patients do not necessarily use treatment on a daily basis; rather, they appear to increase treatment use with the loss of symptom control. The Allergy Diary allowed differentiation between treatments within or between classes (intranasal corticosteroid use containing medications and oral H1-antihistamines). The control of days differed between no [best control], single or multiple treatments (worst control). The present study confirms the usefulness of the Allergy Diary in accessing and assessing everyday use and practice in allergic rhinitis. This pilot observational study uses a very simple assessment (VAS) on a mobile phone, shows novel findings and generates new hypotheses. This article is protected by copyright. All rights reserved.

    SWINGS was a cooperation project between the European Union and India, aiming at implementing state of the art low-cost technologies for the treatment and reuse of domestic wastewater in rural areas of India. The largest wastewater treatment plant consists of a high-rate anaerobic system, followed by vertical and horizontal subsurface flow constructed wetlands with a treatment area of around 1,900 m 2 and a final step consisting of solar-driven anodic oxidation (AO) and ultraviolet (UV) disinfection units allowing direct reuse of the treated water. The implementation and operation of two pilot plants in north (Aligarh Muslim University, AMU) and central India (Indira Gandhi National Tribal University, IGNTU) are shown in this study. The overall performance of AMU pilot plant during the first 7 months of operation showed organic matter removal efficiencies of 87% total suspended solids, 95% 5-day biological oxygen demand (BOD 5 ) and 90% chemical oxygen demand, while Kjeldahl nitrogen removal reached 89%. The UV disinfection unit produces water for irrigation and toilet flushing with pathogenic indicator bacteria well below WHO guidelines. On the other hand, the AO disinfection unit implemented at IGNTU and operated for almost a year has been shown to produce an effluent of sufficient quality to be reused by the local population for agriculture and irrigation.

    In this work we illustrate the approach of the Maastricht Brain Imaging Center to the PBAIC 2007 competition, where participants had to predict, based on fMRI measurements of brain activity, subject driven actions and sensory experience in a virtual world. After standard pre-processing (slice scan time correction, motion correction), we generated rating predictions based on linear Relevance Vector Machine (RVM) learning from all brain voxels. Spatial and temporal filtering of the time series was optimized rating by rating. For some of the ratings (e.g. Instructions, Hits, Faces, Velocity), linear RVM regression was accurate and very consistent within and between subjects. For other ratings (e.g. Arousal, Valence) results were less satisfactory. Our approach ranked overall second. To investigate the role of different brain regions in ratings prediction we generated predictive maps, i.e. maps of the weighted contribution of each voxel to the predicted rating. These maps generally included (but were not limited to) "specialized" regions which are consistent with results from conventional neuroimaging studies and known functional neuroanatomy. In conclusion, Sparse Bayesian Learning models, such as RVM, appear to be a valuable approach to the multivariate regression of fMRI time series. The implementation of the Automatic Relevance Determination criterion is particularly suitable and provides a good generalization, despite the limited number of samples which is typically available in fMRI. Predictive maps allow disclosing multi-voxel patterns of brain activity that predict perceptual and behavioral subjective experience. Copyright © 2010 Elsevier Inc. All rights reserved.

  17. Dawn of the electronic age electrical technologies in the shaping of the modern world 1914 to 1945

    Nebeker, Frederik

    2009-01-01

    Much of the infrastructure of today's industrialized world arose in the period from the outbreak of World War I to the conclusion of World War II. It was during these years that the capabilities of traditional electrical engineering became ubiquitous. Even more importantly, it was during this time that a new type of electrical engineering--electronics--emerged. Because of its applications in communications, entertainment, industry, science and medicine, and the military, the electronics industry became a major part of the economy. Dawn of the Electronic Age explores how this engineering knowledge and its main applications developed in various scientific, economic, and social contexts, and explains how each was profoundly affected by electrical technologies. It takes an international perspective and a narrative approach, unfolding the story chronologically. --from publisher description.

    The objective is promote national status and potential of Nuclear radiation industry, and take a world-wide leading role in radiation industry, by developing and hosting the first WNU Radiation Technology School. RI School (World Nuclear University Radioisotope School) is the three-week program designed to develop and inspire future international leaders in the field of radioisotope for the first time. The project would enable promote abilities of radioactive isotopes professions, and to build the human network with future leaders in the world-wide nuclear and radiation field. Especially by offering opportunity to construct human networks between worldwide radiation field leaders of next generation, intangible assets and pro-Korean human networks are secured among international radiation industry personnel. This might enhance the power and the status of Korean radiation industries, and establish the fundamental base for exporting of radiation technology and its products. We developed the performance measurement method for the school. This shows that 2010 WNU RI School was the first training program focusing on the radioisotope and very useful program for the participants in view of knowledge management and strengthening personal abilities. Especially, the experiences and a human network with world-wide future-leaders in radiation field are most valuable asset. It is expected that the participants could this experience and network developed in the program as a stepping stone toward the development of Korea's nuclear and radiation industry.

    China's manufacturing industries are traditionally energy-intensive sectors and are responsible for over half of the country's total CO 2 emissions. In this paper, we propose a global meta-frontier non-radial directional distance function approach to measure the CO 2 emissions performance of Chinese manufacturing sectors during the period of 1990–2012. This approach allows us to simultaneously consider technological heterogeneity in manufacturing, non-radial slacks, and undesirable outputs. The global level of environmental technology is incorporated into the efficiency model to improve discriminating power and comparability. The results indicate significant differences in CO 2 -emissions-reduction performance among five broad groups of Chinese manufacturing industries. The “global technologies/ innovators group” is the most efficient under meta-frontier technologies, with the smallest technology gap. Meanwhile, the “energy-/resource-intensive commodities group” is, on average, the least efficient. Therefore, the Chinese government should implement targeted policies that encourage firms in the global technologies/innovators group to increase market share while supporting those in the energy-/resource-intensive commodities group to upgrade their technologies. - Highlights: • Global meta-frontier non-radial directional distance function approach is proposed. • It measures CO 2 emissions performance of Chinese manufacturing during 1990–2012. • The impact of group heterogeneity is incorporated. • Global technologies/innovators group is the most efficient under meta-frontier. • Energy-/resource-intensive commodities group is, on average, the least efficient.

    Achieving adoption, use, and integration of information and communication technology by healthcare clinicians in the workplace is recognized as a challenge that requires a multifaceted approach. This article explores community health nurses' engagement with information and communication technology as part of a larger research project that investigated the delivery of self-management support to people with chronic obstructive pulmonary disease. Following a survey of computer skills, participants were provided with computer training to support use of the project information system. Changes in practice were explored using action research meetings and individual semistructured interviews. Results highlight three domains that affected nurses' acceptance, utilization, and integration of information and communication technology into practice; environmental issues; factors in building capacity, confidence, and trust in the technology; and developing competence. Nurses face individual and practice challenges when attempting to integrate new processes into work activities, and the use of participatory models to support adoption is recommended.

    2000-01-01

    Literate but unskilled--and largely female--labor has thus far fueled the tremendous increase in manufactured exports of garments and microelectronic products from the Third World to the industrially advanced economies of the North. The future growth of these sectors, however, may require literate and skilled workers--a category in which women are woefully under-represented, especially in the Third World. In the case of the garment industry, defensive innovation in the industrially advanced countries, including automation and flexible management, has initiated a relocation of jobs to these countries or to offshore locations geographically close to their markets. Automated garment production in these countries requires fewer but computer-literate workers. In the case of microelectronics, development policies of East Asian countries and the competitive pressures on start-up companies in the North have led to an increased demand for computer-literate, skilled technicians over the unskilled and overwhelmingly female workforce of manual-assembly workers. Women's continued employment and advancement in these industries globally will depend upon their acquisition of new technical skills. The ratification by the 1995 international women's conference at Beijing of the demand for better access to education and skills training for women, especially in the Third World, is a step in the right direction.

  15. Poly-Victimization and Peer Harassment Involvement in a Technological World.

    2018-03-01

    This article explores the ways poly-victimized youth (those experiencing multiple different types of victimization over the course of 1 year) use technology to interact with peers. Particular attention is given to the peer harassment victimization and perpetration experiences of poly-victimized youth compared with less victimized and non-victimized youth-both overall and through technology. Data were collected as part of the Technology Harassment Victimization (THV) study; a national survey of 791 youth, ages 10 to 20 across the United States. Study results document the heightened risks that poly-victimized youth experience when interacting with peers. Low and high poly-victimized youth were both at significantly greater risk of being dual victims and perpetrators of peer harassment when compared with non-victimized youth even after taking into account other potentially explanatory factors. This was not found to be the case for less victimized youth. This was true for high poly-victims and technology-involved harassment risk as well. There were indications that poly-victimized youth were interacting with peers in more intense and risky ways in general using new technology. The increase in attention to poly-victimization in recent years has importantly identified the detrimental role that experiencing different forms of victimization have on youth. This study not only adds to that literature but suggests that there is an opportunity to interrupt additional victimization by understanding how poly-victimized youth interact with peers before and during adolescence. Although preliminary, the differences in technology use by poly-victimized youth versus others suggest that more information is needed to understand how they are relating to peers in both positive and risky ways in this environment.

  3. Process analysis of technological competition and logistical substitution in world electronuclear system to the year 1986

    Energy Technology Data Exchange (ETDEWEB)

    Caira, M.; Spezia, U. (Rome Univ. La Sapienza (Italy))

    On the basis of the definitions established within the framework of Marchetti's logistic substitution model, an analysis of the process of technological competition at the international level among the different types of reactors was performed, through a quantitative and qualitative examination of the evolution of the role and the penetration of each of the industrially mature design configurations. The analysis covers the period between 1956 - the year the first reactors for civilian use began service - and 1985, and thus excludes the period of the 'Chernobyl emergency' and the following years, with the aim of obtaining an overall picture of the penetration of nuclear technologies in a market not influenced by obvious factors that condition the demand. The results of the analysis show a clear process of decline in the Western and Soviet graphite reactor types of the first generation (GCR and LGR), as well as, the role of predominant technology that is still undergoing an intense phase of expansion being assumed by the pressurized light water reactors (PWR). After the great successes of the years around 1970, the boiling water reactor (BWR) type seems to be undergoing a phase of reconsideration, while for the entire range of reactor types of the more recent generation (LMFBR, AGR, HTGR), no significant competitor capable of posing a serious threat to the PWR type has yet emerged, even after a phase of technological development that has lasted since 1972.

    The Vision Research Lab at NASA John Glenn Research Center is headed by Dr. Rafat Ansari. Dr. Ansari and other researchers have developed technologies that primarily use laser and fiber optics to non-invasively detect different ailments and diseases of the eye. One of my goals as a LERCIP intern and ACCESS scholar for the 2004 summer is to inform other NASA employees, researchers and the general public about these technologies through the development of a website. The website incorporates the theme that the eye is a window to the body. Thus by investigating the processes of the eye, we can better understand and diagnosis different ailments and diseases. These ailments occur in not only earth bound humans, but astronauts as well as a result of exposure to elevated levels of radiation and microgravity conditions. Thus the technologies being developed at the Vision Research Lab are invaluable to humans on Earth in addition to those astronauts in space. One of my first goals was to research the technologies being developed at the lab. The first several days were spent immersing myself in the various articles, journals and reports about the theories behind Dynamic Light Scattering, Laser Doppler Flowmetry, Autofluoresence, Raman Spectroscopy, Polarimetry and Oximetry. Interviews with the other researchers proved invaluable to help understand these theories as well gain hands on experience with the devices being developed using these technologies. The rest of the Vision Research Team and I sat down and discussed how the overall website should be presented. Combining this information with the knowledge of the theories and applications of the hardware being developed, I worked out different ideas to present this information. I quickly learned Paint Shop Pro 8 and FrontPage 2002, as well as using online tutorials and other resources to help design an effective website. The Vision Research Lab website incorporates the anatomy and physiology of the eye, different diseases

    Biotechnology is a controversial subject that involves a range of scientific principles from basic tissue culture to genetic manipulation. Proponents include private sector capitalists, public sector researchers, and developing nation governments. Opponents include environmental organizations and social organizations involved in protecting the rights of developing nations. Biotechnology is being presented as the next step after the Green Revolution and the only way that the people of the developing world will be able to feed themselves in the next half century. Research by industrialized nations world wide total an estimated $11 billion with 66% being contributed by the private sector. Biotechnology represents somewhat of a dilemma. Since the majority of the work is being done by the private sector the interests of shareholders and profit are greater done by the private sector the interests of shareholders and profit are greater than that of public welfare or safety. The Consultative Group on International Agricultural Research (CGIAR) is one public sector group that is concerned about this problem. The countries of the developing world fall into 2 categories in relation to use of biotechnology: (1) those that have the potential to adapt imported biotechnologies to local conditions; (2) those that have little or no applied research capacity to effectively use biotechnologies. Currently only Brazil, China, India, and Thailand belong in the 1st category, all other developing countries fall into the 2nd. CGIAR believes it can help in 2 ways: (1) it can provide a bridge for needed information and germplasm between developed and developing countries; (2) it can help to ensure that the agricultural needs of developing countries are not lost. In 1990 CGIAR's plant and animal biotechnology research totaled $14.5 million which was less than 5% of the total CGIAR budget. Networking and institutions building are areas that CGIAR focuses on in an attempt to increase its affect

    Air Products and Chemicals, along with development participants and in association with the U.S. Department of Energy, has made substantial progress in developing a novel air separation technology. Unlike conventional cryogenic processes, this method uses high-temperature ceramic membranes to produce high-purity oxygen. The membranes selectively transport oxygen ions with high flux and infinite theoretical selectivity. Reaction-driven ceramic membranes are fabricated from non-porous, multi-component metallic oxides, operate at temperatures typically over 700°C, and have exceptionally high oxygen flux and selectivity. Oxygen from low-pressure air permeates as oxygen ions through the ceramic membrane and is consumed through chemical reactions, thus creating a chemical driving force that pulls oxygen ions across the membrane at high rates. The oxygen reacts with a hydrocarbon fuel in a partial oxidation process to produce a hydrogen and carbon monoxide mixture – synthesis gas. This project expands the partial-oxidation scope of ITM technology beyond natural gas feed and investigates the potential for ITM reaction-driven technology to be used in conjunction with gasification and pyrolysis technologies to provide more economical routes for producing hydrogen and synthesis gas. This report presents an overview of the ITM reaction-driven development effort, including ceramic materials development, fabrication and testing of small-scale ceramic modules, ceramic modeling, and the investigation of gasifier integration schemes

    Ever since the early 1960s, the United Nations has acknowledged science and technology as integral components of developmental policies. While this connection was initially perceived as the application of findings from scientific research conducted in the Global North, by the 1970s, in the context of negotiations for a New International Economic Order, attention shifted towards the structures of the global management of science. Accordingly in 1979 the UN Conference on Science and Technology for Development discussed possibilities of strengthening scientific and technological research and teaching, particularly in developing countries. During subsequent negotiations conflicts erupted over the question of how to finance programs supporting science. When the G‑77 nations presented plans involving automatic financing schemes, these concepts proved incompatible with the insistence of important industrialized countries that all financial contributions should be voluntary. These discussions appeared to be concerned with the size of financial contributions. In a larger perspective, however, they reflected fundamentally different concepts of a world order, turning science and technology into a medium for far-reaching debates about questions of global development and justice.

    2015-03-01

    A long-standing debate in Pleistocene archaeology concerns the sources of variation in the technology of colonizing hunter-gatherers. One prominent example of this debate is Clovis technology (13,350-12,500 calendar years before present), which represents the earliest widespread and currently recognizable remains of hunter-gatherers in North America. Clovis projectile points appear to have been made the same way regardless of region, but several studies have documented differences in shape that appear to be regional. Two processes have been proposed for shape variation: (1) stochastic mechanisms such as copy error (drift) and (2) Clovis groups adapting their hunting equipment to the characteristics of prey and local habitat. We used statistical analysis of Clovis-point flake-scar pattern and geometric morphometrics to examine whether drift alone could cause significant differences in the technology of Stone Age colonizing hunter-gatherers. Importantly, our analysis was intraregional to rule out a priori environmental adaptation. Our analysis confirmed that the production technique was the same across the sample, but we found significant shape differences in Clovis point populations made from distinct stone outcrops. Given that current archaeological evidence suggests stone outcrops were "hubs" of regional Clovis activity, our dichotomous, intraregional results quantitatively confirm that Clovis foragers engaged in two tiers of social learning. The lower, ancestral tier relates to point production and can be tied to conformist transmission of tool-making processes across the Clovis population. The upper, derived tier relates to point shape, which can be tied to drift that resulted from increased forager interaction at different stone-outcrop hubs and decreased forager interaction among groups using different outcrops. Given that Clovis artifacts represent the earliest widespread and currently recognizable remains of hunter-gatherers in North America, our results

  19. Platforms, Communities, and Business Ecosystems: Lessons Learned about Technology Entrepreneurship in an Interconnected World

    Directory of Open Access Journals (Sweden)

    2013-02-01

    Full Text Available Technology entrepreneurs are increasingly building businesses that are deliberately anchored in platforms, communities, and business ecosystems. Nonetheless, actionable, evidence-based advice for technology entrepreneurs is scarce. Platforms, communities, and ecosystems are active areas of management research, but until recently, each has been studied in separate research programs, with results published in different venues, and often examined from the perspectives of incumbent managers or policy makers rather than entrepreneurs and new entrants. This article re-examines these phenomena from the perspective of technology entrepreneurs facing strategic choices about interconnected systems of platforms, communities, and business ecosystems, and decisions about the nature and extent of participation. It brings together insights from a wide range of published sources. For entrepreneurs, it provides an accessible introduction to what can be a complex topic, identifies a set of practical considerations to be accounted for in decision-making, and offers a guide for further reading. For researchers and graduate students seeking practical and high-impact research problems, it provides an entry point to the research literature and identifies gaps in the current body of knowledge, especially regarding the system-level interactions between subsystems.

    1992-03-01

    In its August meeting in Geneva, the Energy and Industry Subcommittee (EIS) of the Policy Response Panel of the Intergovernmental Panel on Climate Change (IPCC) identified a series of reports to be produced. One of these reports was to be a synthesis of available information on global electricity end-use efficiency, with emphasis on developing nations. The report will be reviewed by the IPCC and approved prior to the UN Conference on Environment and Development (UNCED), Brazil, June 1992. A draft outline for the report was submitted for review at the November 1991 meeting of the EIS. This outline, which was accepted by the EIS, identified three main topics to be addressed in the report: status of available technologies for increasing electricity end-use efficiency; review of factors currently limiting application of end-use efficiency technologies; and review of policies available to increase electricity end-use efficiency. The United States delegation to the EIS agreed to make arrangements for the writing of the report.

    2018-01-01

    FuelUp&Go! is a technology-driven food literacy program consisting of six in-person skill building sessions as well as fitness trackers, text messages, and a companion website. A community-based participatory research approach was used with adolescents who were recruited to participate in a Kid Council. Qualitative data were collected about the use of surveys, program activities, recipes, technology and text messages, and music and incentives. Changes suggested by Kid Councilmembers informed the design and development of a pilot program. Participants were recruited for the pilot program and completed pre- and postintervention surveys. The results indicated food-related knowledge remained low but increased from baseline to follow-up. Attitudes toward vegetables and physical activity increased slightly. Self-reported participation in physical activity and consumption of sugar-added beverages moved in positive directions. These findings suggest that community-based participatory research approach is an effective approach to engage adolescents in the development of a technology-driven food literacy program.

  4. Sustaining World Food Security with Improved Cassava Processing Technology: The Nigeria Experience

    Directory of Open Access Journals (Sweden)

    Peter O. Kolawole

    2010-11-01

    Full Text Available Cassava is a very important food crop that is capable of providing food security. However, a lot of problems prevent the development and use of modern equipment for its production. Most of the cassava produced still comes from peasant farmers who depend on manual tools for their field operations and these farmers have made Nigeria the world’s largest producer of the crop. An increase in production of cassava to sustain the world food security needs improved machinery to allow its continuous cultivation and processing. Reasons for the low success recorded in the mechanization of cassava harvesting and processing were traced, and the attempts that have been made in the recent past by various engineers in Nigeria researching towards achieving mechanized harvesting and processing of cassava are well explained. The machinery required for cassava production in Africa, the development of new machines, and the need for more research and development in harvesting and processing machineries, which can reduce poverty worldwide and make food available and accessible for all, are also discussed. Research efforts made and the challenges facing the engineers, farmers, scientists and food processors towards achieving mechanical harvesting and processing of cassava are presented. Breeding a cassava variety with a regular shape for easy mechanization is one solution that could help the engineers worldwide.

    2009-09-01

    Full Text Available A variety of challenges to biodiversity and biosystematics research are discussed. Despite escalating estimates of the biodiversity of the planet, resources being devoted to advance this knowledge have been in decline. Despite the proliferation of information technologies, the focus of knowledge has frequently shifted to making information readily available, rather than generating new information. The principles of authorial responsibility and of explicit documentation of knowledge are under siege. The shortfall of investment in training, research, and collections management (the ''taxonomic deficit'' has lead to a ''taxonomic impediment'' to ecological research, at a time when rates of extinction appear to be rising dramatically. The contents of present volume represent stepping-stones of biodiversity research – a discipline vital to the future of life on the planet.

  8. There's a World Going on Underground: Imaging Technologies to Understand Root Growth Dynamics and Rhizosphere Interactions

    Science.gov (United States)

    Topp, C. N.

    2016-12-01

    Our ability to harness the power of plant genomics for basic and applied science depends on how well and how fast we can quantify the phenotypic ramifications of genetic variation. Plants can be considered from many vantage points: at scales from cells to organs, over the course of development or evolution, and from biophysical, physiological, and ecological perspectives. In all of these ways, our understanding of plant form and function is greatly limited by our ability to study subterranean structures and processes. The limitations to accessing this knowledge are well known - soil is opaque, roots are morphologically complex, and root growth can be heavily influenced by a myriad of environmental factors. Nonetheless, recent technological innovations in imaging science have generated a renewed focus on roots and thus new opportunities to understand the plant as a whole. The Topp Lab is interested in crop root system growth dynamics and function in response to environmental stresses such as drought, rhizosphere interactions, and as a consequence of artificial selection for agronomically important traits such as nitrogen uptake and high plant density. Studying roots requires the development of imaging technologies, computational infrastructure, and statistical methods that can capture and analyze morphologically complex networks over time and at high-throughput. The lab uses several imaging tools (optical, X-ray CT, PET, etc.) along with quantitative genetics and molecular biology to understand the dynamics of root growth and physiology. We aim to understand the relationships among root traits that can be effectively measured both in controlled laboratory environments and in the field, and to identify genes and gene networks that control root, and ultimately whole plant architectural features useful for crop improvement.

    2011-04-01

    Preceptorship/mentorship is designed to socialize students into the nursing profession, promote their confidence/competence and foster their critical thinking ability. In today's global context, opportunities exist for local, rural, national and international student placements which provide exciting and mutually rewarding preceptorship experiences. Despite the recognized value of those involved in preceptorship/mentorship, however, little progress has been made regarding the development of an infrastructure that effectively supports their ongoing education. This project, piloted from October 2008 to February 2009, leveraged our established research and teaching experience in preceptorship with technologies that allowed us to create an accessible and engaging e-learning space designed to support preceptors in a seamless fashion, improve the quality of the student preceptorship and enhance professional teaching capacity. A purposive sample of 25 preceptors was selected with a total of 18 preceptors successfully completing the five month program. Upon completion, participants were surveyed and individually interviewed. Data analysis revealed the program to be informative, supportive and highly valued. Knowledge derived from this study can: a) further enrich the substantive nature and infrastructure of online preceptor education; and b) contribute to clarifying best practices for preceptor support, facilitation, and ongoing professional development with a view to enhancing the preceptorship experience.

    Full Text Available The article highlights the latest developments in the field of Digital Humanities. It indicates in which ways these technologies are already used in the historical and geographical science throughout the world and how they could be integrated systematically into Byzantine Studies. In the first part of the article international projects, which are based on GIS (Geographic Information Systems, and their links in the World Wide Web are presented. In the second part the author shows on the basis of his scholarly results on the historical geography of Byzantine Macedonia, how medieval written sources can be transferred into digital format in order to achieve a higher level of spatial data analysis. The neglect of this important and recent scholarly approach in the 21st century could lead to the marginalisation of Byzantine Studies in general, and of the historical geography of the Byzantine Empire in particular.

    Highlights: ► Uncertainty impacts the expected cost of novel nuclear technology development. ► A real-options methodology is presented to analyse expected cost under uncertainty. ► The methodology is applied to analyse a demonstration commercial ADSR park design. ► Flexibility inserted early in design demonstrably reduces expected development cost. ► The method improves existing approaches for design and engineering decision-making. - Abstract: This paper presents a simple, systematic, and integrated methodology to analyse the expected Levelised Cost Of Electricity (LCOE) generation of a new nuclear technology facing significant technological uncertainty. It shows that flexibility in the design and deployment strategy of a demonstration commercial thorium-fuelled Accelerator-Driven Subcritical Reactor (ADSR) park significantly reduces the expected LCOE. The methodology recognizes early in the conceptual design a range of possible technological outcomes for the ADSR accelerator system. It suggests appropriate flexibility “on” and “in” the first-of-a-kind design to modify the demonstration park development path in light of uncertainty realizations. It then incorporates these uncertainties and flexibilities in the design evaluation mechanism. The methodology improves existing approaches for design and engineering decision-making, providing guidance for government support for a new, secure, clean, and publicly acceptable alternative technology for power generation.

  16. Marine bioacoustics and technology: The new world of marine acoustic ecology

    Science.gov (United States)

    Hastings, Mardi C.; Au, Whitlow W. L.

    2012-11-01

    Marine animals use sound for communication, navigation, predator avoidance, and prey detection. Thus the rise in acoustic energy associated with increasing human activity in the ocean has potential to impact the lives of marine animals. Thirty years ago marine bioacoustics primarily focused on evaluating effects of human-generated sound on hearing and behavior by testing captive animals and visually observing wild animals. Since that time rapidly changing electronic and computing technologies have yielded three tools that revolutionized how bioacousticians study marine animals. These tools are (1) portable systems for measuring electrophysiological auditory evoked potentials, (2) miniaturized tags equipped with positioning sensors and acoustic recording devices for continuous short-term acoustical observation rather than intermittent visual observation, and (3) passive acoustic monitoring (PAM) systems for remote long-term acoustic observations at specific locations. The beauty of these breakthroughs is their direct applicability to wild animals in natural habitats rather than only to animals held in captivity. Hearing capabilities of many wild species including polar bears, beaked whales, and reef fishes have now been assessed by measuring their auditory evoked potentials. Miniaturized acoustic tags temporarily attached to an animal to record its movements and acoustic environment have revealed the acoustic foraging behavior of sperm and beaked whales. Now tags are being adapted to fishes in effort to understand their behavior in the presence of noise. Moving and static PAM systems automatically detect and characterize biological and physical features of an ocean area without adding any acoustic energy to the environment. PAM is becoming a powerful technique for understanding and managing marine habitats. This paper will review the influence of these transformative tools on the knowledge base of marine bioacoustics and elucidation of relationships between marine

    This paper presents a comprehensive review and assessment of a demonstration technology transfer and commercialization prouram called "CommTech". The pro-ram was conceived and initiated in early to mid-fiscal year 1995, and extended roughly three years into the future. Market research sources were used to initially gather primary technological problems and needs data from non-aerospace companies in three targeted industry sectors: environmental, surface transportation, and bioengineering. Company-supplied information served as input data to activate or start-up an internal, phased matchmaking process. This process was based on technical-level relationship exploration followed by business-level agreement negotiations. and culminated with project management and execution. Space Act Agreements represented near-term outputs. Company product or process commercialization derived from NASA Glenn support and measurable economic effects represented far-term outputs.

    Randomized controlled trials provide robust data on the efficacy of interventions rather than on effectiveness. Health technology assessment (HTA) agencies worldwide are thus exploring whether real-world data (RWD) may provide alternative sources of data on effectiveness of interventions. Presently, an overview of HTA agencies' policies for RWD use in relative effectiveness assessments (REA) is lacking. To review policies of six European HTA agencies on RWD use in REA of drugs. A literature review and stakeholder interviews were conducted to collect information on RWD policies for six agencies: the Dental and Pharmaceutical Benefits Agency (Sweden), the National Institute for Health and Care Excellence (United Kingdom), the Institute for Quality and Efficiency in Healthcare (Germany), the High Authority for Health (France), the Italian Medicines Agency (Italy), and the National Healthcare Institute (The Netherlands). The following contexts for RWD use in REA of drugs were reviewed: initial reimbursement discussions, pharmacoeconomic analyses, and conditional reimbursement schemes. We identified 13 policy documents and 9 academic publications, and conducted 6 interviews. Policies for RWD use in REA of drugs notably differed across contexts. Moreover, policies differed between HTA agencies. Such variations might discourage the use of RWD for HTA. To facilitate the use of RWD for HTA across Europe, more alignment of policies seems necessary. Recent articles and project proposals of the European network of HTA may provide a starting point to achieve this.

    With more than a million spectators expected to travel among 12 different cities in Brazil during the football World Cup, June 12-July 13, 2014, the risk of the mosquito-transmitted disease dengue fever is a concern. We addressed the potential for a dengue epidemic during the tournament, using a probabilistic forecast of dengue risk for the 553 microregions of Brazil, with risk level warnings for the 12 cities where matches will be played. We obtained real-time seasonal climate forecasts from several international sources (European Centre for Medium-Range Weather Forecasts [ECMWF], Met Office, Meteo-France and Centro de Previsão de Tempo e Estudos Climáticos [CPTEC]) and the observed dengue epidemiological situation in Brazil at the forecast issue date as provided by the Ministry of Health. Using this information we devised a spatiotemporal hierarchical Bayesian modelling framework that enabled dengue warnings to be made 3 months ahead. By assessing the past performance of the forecasting system using observed dengue incidence rates for June, 2000-2013, we identified optimum trigger alert thresholds for scenarios of medium-risk and high-risk of dengue. Our forecasts for June, 2014, showed that dengue risk was likely to be low in the host cities Brasília, Cuiabá, Curitiba, Porto Alegre, and São Paulo. The risk was medium in Rio de Janeiro, Belo Horizonte, Salvador, and Manaus. High-risk alerts were triggered for the northeastern cities of Recife (p(high)=19%), Fortaleza (p(high)=46%), and Natal (p(high)=48%). For these high-risk areas, particularly Natal, the forecasting system did well for previous years (in June, 2000-13). This timely dengue early warning permits the Ministry of Health and local authorities to implement appropriate, city-specific mitigation and control actions ahead of the World Cup.

    and the European Union focused on exploring the technical and commercial viability of future reactor systems. The Forum has selected six innovative nuclear systems for collaborative R and D. Major research initiatives (in China, Europe, Japan, the Republic of Korea and the US) are also focused on innovative nuclear systems to produce hydrogen for fuel cells that could be used in transportation. The IAEA is putting increasing emphasis on the theme of 'energy for development'. An increasing range of nuclear and isotopic techniques is used to address challenges - particularly in the developing world - like for example plant breeding to increase yield and resistance or isotope hydrology to map out groundwater resources. Advance technologies and innovative approaches have been used to prevent the proliferation of nuclear weapons, like satellite imagery and advanced nuclear forensic techniques. A great deal of attention is given to building proliferation resistance into future reactor systems, multilateral approaches to the nuclear fuel cycle and research reactor conversion and return of HEU fuel. The stage is set for change and the future of nuclear technology will depend not only on technological innovation, but also on vision, leadership and multilateral cooperation

    This paper reports on the Lambda Power Supply Group, with headquarters in Melville, Long Island owned by UNITECH PLC, based in Reading in the United Kingdom. The Group forms the greatest Power Supply manufacturing and marketing organization in the world, with sales for 1989/90 in excess of $300 million. World markets have distinct trends which need to be recognized in the years ahead. In general, these trends are now commercially driven and center around: The globalization of world markets and the need to service the same customer in the Far East, North America and Europe. The drive to reduce physical size, improve performance and quality and the need to reduce costs. This requires significant investment in research and development to maintain technological leadership. The increasing speed of new product introductions requires power supply companies to work hand-in-hand with their customers as a partner, or even as an extension of the OEM's own development department. A significant trend within Europe is the perception by Far Eastern equipment manufacturers that, by 1992, trade barriers will be erected, and these large manufacturers are increasingly establishing factories within Europe, where they will need local content in their products. Whilst addressing a Global Market with products which are suitable for worldwide sale, it is important to note that local presence is vital, not only to service the customer, but also to monitor the customers needs which have significant differences in certain markets

    We studied an artificial intelligent assisted interaction between a computer and a human with severe speech and physical impairments (SSPI). In order to speed up AAC, we extended a former study of typing performance optimization using a framework that included head movement controlled assistive technology and an onscreen writing device. Quantitative and qualitative data were collected and analysed with mathematical methods, manual interpretation and semi-supervised machine video annotation. As the result of our research, in contrast to the former experiment's conclusions, we found that our participant had at least two different typing strategies. To maximize his communication efficiency, a more complex assistive tool is suggested, which takes the different methods into consideration.

    Initial hospital discharge to home of technology-dependent children requires extensive training and education of the family caregivers. Education of adult family members should promote positive interactions in a nonthreatening manner while facilitating the development of the knowledge and skills to competently and independently provide all aspects of the medical care. We utilize a training program for adult family members of children who have undergone tracheostomy to facilitate long-term mechanical ventilatory support and who are being prepared for their initial discharge from the hospital to home. A dedicated respiratory therapist family educator directs this program. Multiple teaching tools, activities, and training sessions, based on adult learning theory, are utilized to develop appropriate clinical skills to manage children with tracheostomies and the associated technological supports. We evaluated the effectiveness of our program by administering a written test to caregivers, at the start and the conclusion of their training. We also surveyed the caregivers about their satisfaction with the educational program and the respiratory therapist family educator's performance. We also surveyed employees of the durable medical equipment companies used by the families, regarding the caregivers' knowledge and competency in the home one month following discharge. Our program was associated with a statistically significant improvement in caregiver test performance, and the caregivers expressed a high degree of satisfaction with the program. The employees of the durable medical equipment companies perceived a high degree of knowledge and competence on the part of the home caregivers. Our training program appears to have a positive impact on the educational preparation of caregivers.

    The US urban driving cycle (FTP-75) is widely used to estimate both the emissions under hot engine conditions as well as those associated with the cold start. Applying fast analysis techniques such as chemical ionization mass spectrometry (CI-MS) the warm-up behavior of individual vehicles can be monitored at a time resolution of 1 s. CI-MS has been used to investigate the emissions of methane, benzene and the alkyl benzene class of compounds. The amount of the emissions at cold start influence was deduced from the time-resolved emission data of four gasoline-driven vehicle classes representing the vehicle technology of the last two decades. Overall, the emissions of five EURO-0, 20 EURO-1, 18 EURO-2 and so far of six EURO-3 passenger cars were recorded. The test vehicles were selected from the currently operating Swiss car fleet based on the car sales statistics. The average methane, benzene and alkyl benzene cold start emissions are reported using both, the traditional bag method as well as the regression model. At room temperature a clear reduction of 94%, 81% and 85% was found for the methane, benzene and alkyl benzene cold start emissions from EURO-0 to EURO-3 technology, respectively.

    Reimbursement decisions are conventionally based on evidence from randomised controlled trials (RCTs), which often have high internal validity but low external validity. Real-world data (RWD) may provide complimentary evidence for relative effectiveness assessments (REAs) and cost-effectiveness assessments (CEAs). This study examines whether RWD is incorporated in health technology assessment (HTA) of melanoma drugs by European HTA agencies, as well as differences in RWD use between agencies and across time. HTA reports published between 1 January 2011 and 31 December 2016 were retrieved from websites of agencies representing five jurisdictions: England [National Institute for Health and Care Excellence (NICE)], Scotland [Scottish Medicines Consortium (SMC)], France [Haute Autorité de santé (HAS)], Germany [Institute for Quality and Efficacy in Healthcare (IQWiG)] and The Netherlands [Zorginstituut Nederland (ZIN)]. A standardized data extraction form was used to extract information on RWD inclusion for both REAs and CEAs. Overall, 52 reports were retrieved, all of which contained REAs; CEAs were present in 25 of the reports. RWD was included in 28 of the 52 REAs (54%), mainly to estimate melanoma prevalence, and in 22 of the 25 (88%) CEAs, mainly to extrapolate long-term effectiveness and/or identify drug-related costs. Differences emerged between agencies regarding RWD use in REAs; the ZIN and IQWiG cited RWD for evidence on prevalence, whereas the NICE, SMC and HAS additionally cited RWD use for drug effectiveness. No visible trend for RWD use in REAs and CEAs over time was observed. In general, RWD inclusion was higher in CEAs than REAs, and was mostly used to estimate melanoma prevalence in REAs or to predict long-term effectiveness in CEAs. Differences emerged between agencies' use of RWD; however, no visible trends for RWD use over time were observed.

    1993-01-01

    Intelligent computer aided training systems hold great promise for the application of this technology to mainstream education and training. Yet, this technology, which holds such a vast potential impact for the future of education and training, has had little impact beyond the enclaves of government research labs. This is largely due to the inaccessibility of the technology to those individuals in whose hands it can have the greatest impact, teachers and educators. Simply throwing technology at an educator and expecting them to use it as an effective tool is not the answer. This paper provides a background into the use of technology as a training tool. MindLink, developed by HyperTech Systems, provides trainers with a powerful rule-based tool that can be integrated directly into a Windows application. By embedding expert systems technology it becomes more accessible and easier to master.

  4. Green” Technology and Ecologically Unequal Exchange: The Environmental and Social Consequences of Ecological Modernization in the World-System

    Directory of Open Access Journals (Sweden)

    Eric Bonds

    2015-08-01

    Full Text Available This paper contributes to understandings of ecologically unequal exchange within the world-systems perspective by offering a series of case studies of ecological modernization in the automobile industry. The case studies demonstrate that “green” technologies developed and instituted in core nations often require specific raw materials that are extracted from the periphery and semi-periphery. Extraction of such natural resources causes significant environmental degradation and often displaces entire communities from their land. Moreover, because states often use violence and repression to facilitate raw material extraction, the widespread commercialization of “green” technologies can result in serious human rights violations. These findings challenge ecological modernization theory, which rests on the assumption that the development and commercialization of more ecologically-efficient technologies is universally beneficial.

    2014-01-01

    Highlights: • The augmented REMIND model is used to study the role of energy technologies under a carbon tax. • The scale and timing of fossil fuels with CCS, nuclear, and renewables are examined. • CCS is important but the window of opportunity for its deployment is limited. • The effectiveness of nuclear is strongly linked to its cost performance. • Renewable energy is a long-term mitigation option. - Abstract: In a world with the need of climate protection through emission reduction, China’s domestic mitigation will be put on the national agenda. The large-scale deployment of innovative technologies induced by climate policies is a key determinant for reducing emissions in an effective and efficient manner. A distinguishing feature of the Chinese energy sector (especially electricity generation), is that investment costs are significantly lower than in other world regions. Represented in the methodological framework of the augmented REMIND model, three promising mitigation technologies (also known as technology clusters) in the electricity sector: CCS with advanced coal-generation technologies, nuclear, and renewables are the focus of this study. The scenarios are designed to analyze the roles of these technologies and their associated economic impacts under a climate policy (i.e., a carbon tax). Our results indicate that: (1)Technology policies improving the techno-economic features of low-carbon technologies are insufficient to restrain China’s increasing emissions. (2)Carbon-pricing policies can effectively reduce emissions by making low-carbon options more competitive than conventional fossil fuel alternatives. In the global carbon tax regime framed in this paper, China’s mitigation potential is larger than that of any of other region and the peak of emissions occurs earlier (by 2020) and is 50% lower than in the BASE scenario. (3)CCS is important, but the window of opportunity for its deployment is limited to the near- to mid-term future. It

  7. Will Life Be Worth Living in a World Without Work? Technological Unemployment and the Meaning of Life.

    Science.gov (United States)

    Danaher, John

    2017-02-01

    Suppose we are about to enter an era of increasing technological unemployment. What implications does this have for society? Two distinct ethical/social issues would seem to arise. The first is one of distributive justice: how will the (presumed) efficiency gains from automated labour be distributed through society? The second is one of personal fulfillment and meaning: if people no longer have to work, what will they do with their lives? In this article, I set aside the first issue and focus on the second. In doing so, I make three arguments. First, I argue that there are good reasons to embrace non-work and that these reasons become more compelling in an era of technological unemployment. Second, I argue that the technological advances that make widespread technological unemployment possible could still threaten or undermine human flourishing and meaning, especially if (as is to be expected) they do not remain confined to the economic sphere. And third, I argue that this threat could be contained if we adopt an integrative approach to our relationship with technology. In advancing these arguments, I draw on three distinct literatures: (1) the literature on technological unemployment and workplace automation; (2) the antiwork critique-which I argue gives reasons to embrace technological unemployment; and (3) the philosophical debate about the conditions for meaning in life-which I argue gives reasons for concern.

These studies were assembled into a data-driven framework that invokes successive tiers of testing with margin of exposure (MOE) as the primary metric. The first tier of the framework integrates data from high-throughput in vitro assays, in vitro-to-in vivo extrapolation (IVIVE) pharmacokinetic modeling, and exposure modeling. The in vitro assays are used to separate chemicals based on their relative selectivity in interacting with biological targets and identify the concentration at which these interactions occur. The IVIVE modeling converts in vitro concentrations into external dose for calculation of the point of departure (POD) and comparisons to human exposure estimates to yield a MOE. The second tier involves short-term in vivo studies, expanded pharmacokinetic evaluations, and refined human exposure estimates. The results from the second tier studies provide more accurate estimates of the POD and the MOE. The third tier contains the traditional animal studies currently used to assess chemical safety. In each tier, the POD for selective chemicals is based primarily on endpoints associated with a proposed mode of action, whereas the POD for nonselective chemicals is based on potential biological perturbation. Based on the MOE, a significant percentage of chemicals evaluated in the first 2 tiers could be eliminated from further testing. The framework provides a risk-based and animal-sparing approach to evaluate chemical safety, drawing broadly from previous experience but incorporating technological advances to increase efficiency.

  11. Innovation and Technology Dissemination in Clean Technology Markets and The Developing World: The Role of Trade, Intellectual Property Rights, and Uncertainty

    Full Text Available Innovation is an inherently risky and uncertain process. Many of the broader challenges to innovation in general are both mirrored and exaggerated in clean technology innovation. The development of environmental technologies is further complicated by the public goods nature of knowledge, environmental externalities, and uncertainty. This study on clean technology focuses on recent work on the role of uncertainty, the participation of emerging and developing nations, the controversy surrounding intellectual property rights, and the variety of market actors and strategies in place. The paper also considers the policy instruments that are available, the cost, benefits and consequences of their use. As scholars continue to analyze when, where, why and how clean technology innovations are developed and adopted, it is essential that government policymakers aim to reduce uncertainty and risk, incentivize innovation with effective intellectual property rights, and foster transparency in the market. This continues to be a field of increasing future importance, and a rich area for continued academic study and analysis. Consumers, government policymakers and innovators would all benefit from a greater understanding of the process of technological change in the development, diffusion and financing of clean technologies.

    There is growing evidence that health systems in developed countries are poorly prepared to deal with major incidents. This study aimed to determine the skills required for successful major incident response, the factors that contribute to a successful major incident exercise, and whether there is a role for using novel simulation training (virtual worlds) in preparing for major incidents. This was a qualitative semi-structured interview study. Fourteen health care staff with experience of major incident planning and training in the United Kingdom were recruited. Interviews were content-analyzed to identify emergent themes. The aims and benefits of current exercises were categorized into three major themes: Organizational, Interpersonal, and Cognitive. Participants felt that the main objective of current exercises is to see how a major incident plan is implemented, rather than training individual staff. Communications was the most frequently commented-on area requiring improvement. Participants felt that lack of constructive feedback reduced the effectiveness of the exercises. All participants commented that virtual worlds technology could be successfully utilized for training. The creation of an immersive environment, increased training opportunity, and improved participant feedback were thought to be amongst the greatest benefits. There are clear deficiencies with current major incident preparation. Utilizing virtual worlds technology as an adjunct to existing exercises could improve training and response in the future.

    The steadily growing distances between the world's gas rich regions and consumer zones foreshadow a powerful expansion of the international trade, at an annual rate of around 3.5% by 2020. Flows could then account for about 32% of marketed production. Trade by LNG tanker is very likely to emerge as the winner of this dynamic, with the flexibility it procures exploited to adjust supply to the demand of a more global market. This is today's gamble of an industry which, driven by technological improvements and market potential, is investing massively in new infrastructures

    2017-07-01

    Full Text Available Today the media is replete with stories about Africa rising and enjoying middle –income status. Those promoting the narrative of Africa rising include the World Bank and western –trained elites. The narrative of success assumes that prosperity trickles down to Indigenous communities, who are pictured consuming mobile phones and tablets. At the same time, Hollywood and western media outlets continue to present images of Indigenous Maasai as a cultural export to be consumed. With emphasis on social media narratives, this paper interrogates the continued marginalisation of the Maasai people amidst the myth of a rising Africa. In sum, the Africa rising myth and penetration of ICTs in rural areas masks the dispossession of Maasai means of livelihood, and therefore worsening the groups’ conditions of living.

    Mitra, Bivas

    The study of networks in the form of mathematical graph theory is one of the fundamental pillars of discrete mathematics. However, recent years have witnessed a substantial new movement in network research. The focus of the research is shifting away from the analysis of small graphs and the properties of individual vertices or edges to consideration of statistical properties of large scale networks. This new approach has been driven largely by the availability of technological networks like the Internet [12], World Wide Web network [2], etc. that allow us to gather and analyze data on a scale far larger than previously possible. At the same time, technological networks have evolved as a socio-technological system, as the concepts of social systems that are based on self-organization theory have become unified in technological networks [13]. In today’s society, we have a simple and universal access to great amounts of information and services. These information services are based upon the infrastructure of the Internet and the World Wide Web. The Internet is the system composed of ‘computers’ connected by cables or some other form of physical connections. Over this physical network, it is possible to exchange e-mails, transfer files, etc. On the other hand, the World Wide Web (commonly shortened to the Web) is a system of interlinked hypertext documents accessed via the Internet where nodes represent web pages and links represent hyperlinks between the pages. Peer-to-peer (P2P) networks [26] also have recently become a popular medium through which huge amounts of data can be shared. P2P file sharing systems, where files are searched and downloaded among peers without the help of central servers, have emerged as a major component of Internet traffic. An important advantage in P2P networks is that all clients provide resources, including bandwidth, storage space, and computing power. In this chapter, we discuss these technological networks in detail. The review

    The developments in apheresis techniques and their clinical applications world-wide are technologically driven. In the past, apheresis survey statistics have high-lighted both the differences by region in clinical practice and in the types of technologies utilized. Such differences have provided a basis for the scientific and clinical assessments of these apheresis technologies and their clinical outcomes and have stimulated the marketing and business development of new technologies world-wide. A review of the regional practices and technologies utilized provides a perspective on the future role of apheresis and its developments in clinical practice. While technology is a driving force for the development of new techniques for clinical practice, it is not the only market force. For technology introduction, several other important issues need to be considered. Regulations at the local and, most importantly, the federal level impact the timing for new technology introduction. Reimbursement by healthcare payers is critically important from the initiation of the development of a technology through its clinical use. Clinical trials are critically important to show the safety and clinical- and cost-effectiveness of the technology in order for payers to provide reimbursement for its use, but these trials are sometimes long and costly. Research funding availability at the governmental and commercial levels critically impacts new technology investigation and its introduction. Apheresis technology developments offer new hopes and promises for the clinical team; however, their development, introduction, and utilization will be influenced by the prevailing market forces.

    In the near term NASA is entering into the peak activity period of the Earth Observing System (EOS). The EOS AM-1 /"Terra" spacecraft is nearing launch and operation to be followed soon by the New Millennium Program (NMP) Earth Observing (EO-1) mission. Other missions related to land imaging and studies include EOS PM-1 mission, the Earth System Sciences Program (ESSP) Vegetation Canopy Lidar (VCL) mission, the EOS/IceSat mission. These missions involve clear advances in technologies and observational capability including improvements in multispectral imaging and other observing strategies, for example, "formation flying". Plans are underway to define the next era of EOS missions, commonly called "EOS Follow-on" or EOS II. The programmatic planning includes concepts that represent advances over the present Landsat-7 mission that concomitantly recognize the advances being made in land imaging within the private sector. The National Polar Orbiting Environmental Satellite Series (NPOESS) Preparatory Project (NPP) is an effort that will help to transition EOS medium resolution (herein meaning spatial resolutions near 500 meters), multispectral measurement capabilities such as represented by the EOS Moderate Resolution Imaging Spectroradiometer (MODIS) into the NPOESS operational series of satellites. Developments in Synthetic Aperture Radar (SAR) and passive microwave land observing capabilities are also proceeding. Beyond these efforts the Earth Science Enterprise Technology Strategy is embarking efforts to advance technologies in several basic areas: instruments, flight systems and operational capability, and information systems. In the case of instruments architectures will be examined that offer significant reductions in mass, volume, power and observational flexibility. For flight systems and operational capability, formation flying including calibration and data fusion, systems operation autonomy, and mechanical and electronic innovations that can reduce

    2017-06-01

    Restructuring of undergraduate medical education (UGME) has occurred from time to time over the past century. Many influences, including the persuasive report of Abraham Flexner in 1910, acted to reorganize medical education in the early twentieth century [1, 2]. In his report, Flexner called on American medical schools to enact higher graduation standards and to stringently adhere to the protocols of mainstream science in their teaching. Prior to this report, UGME had changed little over the previous century but over the last several decades, reform within medical education has become routine. This increasing rate of change has been challenging for those within the realm of undergraduate medical education and can be frustrating to those outside this sphere. Today, the Association of American Medical Colleges (AAMC) and Liaison Committee on Medical Education (LCME) are typically the driving forces behind such changes, along with acceleration of advances in medical care and technology. The number of changes in the last decade is significant and warrants review by those interested or involved in education of medical students. This article aims to provide a summary of recent changes within UGME. Within the article, changes in both the pre-clerkship (1st and 2nd years) and clinical years (3rd and 4th) will be discussed. Finally, this review will attempt to clarify new terminology and concepts such as the recently released Core Entrustable Professional Activities (EPAs). The goal of these UGME changes, as with Flexner's reform, is to ensure future physicians are better prepared for patient care.

    The aim of this study is to compare demographic/disease characteristics of users versus nonusers of a do-it-yourself (DIY) mobile technology system for diabetes (Nightscout), to describe its uses and personalization, and to evaluate associated changes in health behaviors and outcomes. A cross-sectional, household-level online survey was used. Of 1268 household respondents who were members of the CGM in the Cloud Facebook group, there were 1157 individuals with diabetes who provided information about Nightscout use. The majority of individuals with diabetes in the household sample were 6-12 years old (followed by 18 years and above, and 13-17 years), non-Hispanic whites (90.2%), with type 1 diabetes (99.4%). The majority used an insulin pump (85.6%) and CGM (97.0%) and had private health insurance (83.8%). Nightscout use was more prevalent among children compared with adolescents and adults. Children used Nightscout for nighttime, school, sporting events, and travel; adults used it for nighttime, work, travel, and sporting events. Whereas the majority of adults viewed their own data without assistance from others, among pediatric users, a median of three individuals (range: 0-8) viewed Nightscout, with a median of three devices per viewer (range: 0-7). Individuals reported that after Nightscout adoption, they checked blood glucose values with a meter less often; bolused more frequently; gave more boluses without checking first with a blood glucose meter; and experienced significant improvements in HbA1c and quality of life. The Nightscout Project is a patient-driven mobile technology for health and may have beneficial effects on glycemic control and quality of life.

    Cerium-doped single crystals (Ce:LuAG, Ce:YAG, Ce:GAGG, Ce:GdYAG) have been investigated as stationary phosphor candidates for blue laser driven solid-state lighting without heat sink. The luminous properties of the single crystals are superior compared to the commercial ceramic powder phosphor wheels (Ce3+: Y3Al5O12). The high-power blue laser diode driven temperature increase of the crystals versus quantum efficiency is experimentally measured and discussed. We have carried out realistic measurements at high excitation power levels and at high temperatures. Limitation of phosphors as stationary sources is determined for commercial usage. The measurements were done without any heat sink to see the relative comparison of SCPs in the worst-case scenarios. The results indicate that Gd and Ga addition decreases the luminescence quenching temperature. Based on their superior properties, these single crystals can serve as potential phosphor candidates for high-power blue diode laser driven picture projectors for the green and red channels.

  14. Connections beyond the margins of the power grid Information technology and the evolution of off-grid solar electricity in the developing world

    Science.gov (United States)

    Alstone, Peter Michael

    This work explores the intersections of information technology and off-grid electricity deployment in the developing world with focus on a key instance: the emergence of pay-as-you-go (PAYG) solar household-scale energy systems. It is grounded in detailed field study by my research team in Kenya between 2013-2014 that included primary data collection across the solar supply chain from global businesses through national and local distribution and to the end-users. We supplement the information with business process and national survey data to develop a detailed view of the markets, technology systems, and individuals who interact within those frameworks. The findings are presented in this dissertation as a series of four chapters with introductory, bridging, and synthesis material between them. The first chapter, Decentralized Energy Systems for Clean Electricity Access, presents a global view of the emerging off-grid power sector. Long-run trends in technology create "a unique moment in history" for closing the gap between global population and access to electricity, which has stubbornly held at 1-2 billion people without power since the initiation of the electric utility business model in the late 1800's. We show the potential for widespread near-term adoption of off-grid solar, which could lead to ten times less inequality in access and also ten times lower household-level climate impacts. Decentralized power systems that replace fuel-based incumbent lighting can advance the causes of climate stabilization, economic and social freedom and human health. Chapters two and three are focused on market and institutional dynamics present circa 2014 in for off-grid solar with a focus on the Kenya market. Chapter 2, "Off-grid Power and Connectivity", presents our findings related to the widespread influence of information technology across the supply chain for solar and in PAYG approaches.

    Haynes, Ray; Hirschy, Anita

    2013-01-01

    On projects that require Earned Value Management (EVMS) Certification, it is critical to quickly prepare for and then successfully obtain certification. This is especially true for government contracts. Projects that do poorly during the review are subject to financial penalties to their company and they lose creditability with their customer creating problems with the project at the outset. At East Tennessee Technology Park (ETTP), we began preparing for Department of Energy (DOE) certification early during proposal development. Once the contract was awarded, while still in transition phase from the previous contractor to our new company, we immediately began reviewing the project controls systems that were in place on the project and determined if any replacements needed to be made immediately. The ETTP contract required the scheduling software to be upgraded to Primavera P6 and we determined that no other software changes would be done prior to certification. Next, preparation of the Project Controls System Description (PCSD) and associated procedures began using corporate standards as related to the project controls systems. During the transition phase, development was started on the Performance Measurement Baseline which is the resource loaded schedule used to measure our performance on the project and which is critical to good Earned Value Management of the project. Early on, and throughout the baseline review, there was positive feedback from the Department of Energy that the quality of the new baseline was good. Having this superior baseline also contributed to our success in EVMS certification. The combined companies of URS and CH2M Hill had recent experience with certifications at other Department of Energy sites and we were able to capitalize on that knowledge and experience. Generic PCSD and procedures consistent with our co-operations approach to Earned Value Management were available to us and were easily tailorable to the specifics of our contract

  1. Uranium enrichment in South Africa: from the world-unique Z-plant to the use of high-technology lasers

    International Nuclear Information System (INIS)

    McDowell, M.W.

    1995-01-01

    A historical discussion of the technology used in South Africa for the enrichment of uranium, as well as other technological spin-offs for the country that followed from the construction of the Z-plant. The national energy strategy and objectives of the government during the Apartheid years resulted in the development of several large-scale energy projects. The pressure of sanctions forced the Z-plant to be rushed into operation at an uneconomical capacity of 250 000 SWU per annum. In 1994 this implied that enriched uranium was produced at a cost of $200 per SWU while the world market price was below $90. While the production of enriched uranium at the Z-plant ceased early in 1995, the expertise gained will not be lost entirely. As a result of the high energy and financial capital intensive current methods of producing enriched uranium, research started in the early 1970's into alternative production processes making use of lasers. South Africa has opted for the MLIS (molecular laser isotope separation) process, as a result of its vast experience gained from the Z-plant in the handling of the molecular input gas UF6 (uranium hexafluoride), and this has been under development since the early 1980's. During 1994 significant progress was made with MLIS, in particular with single-step enrichment from natural uranium to better than 4% uranium 235 on a macro scale. The Atomic Energy Corporation of South Africa's strategy is to licence the process internationally. 3 tabs., 3 figs

    2016-12-01

    Full Text Available The concept of ‘smart’ is increasingly used in the commercial environment, and relates to a perception of technological intelligence. The concept of ‘Internet of Things’ (IoT has also become a reality that makes a different approach to managing physical assets necessary. With this technological intelligence come vast quantities of asset data and the analysis thereof, which has proven to add value to asset management. To capitalise on and expand this value creation, smart asset management (SAM came into being by incorporating proven methodologies and applying these in real-time management structures. This article offers a review of the existing literature, and aims to create industry awareness about the business potential of incorporating SAM into automated asset environments for strategic management decision-making.

    Currently, there are two challenges or threats to the Nuclear Power community. One is the anti nuclear mood after the East Japan earthquake one year ago and the subsequent nuclear disaster. We are not sure at this moment when this mood will be eased. The other threat is the recent shale gas boom (or may be called even a revolution) that began in UA and will be spread to all over the world soon. This second threat is just as serious as the first one. Nuclear power will not receive the attention it used to a few years ago. Economically, it may be ok, however, it will be a disaster to the future of mankind, because shale gas will never solve the problem of global warming. Until now, nuclear power is the only alternative to the fossil energy to save the world. That is why the nuclear power community needs a breakthrough and it is obvious what kind of breakthrough is needed. World needs a safer and cleaner nuclear power plant. A nuclear power plant that will not cause a disaster and that will produce radio toxic nuclear waste as small as possible. At the moment, the closest system is the accelerator driven system (ADS). First of all, it is safer in a disaster such as an earthquake, because the deriving accelerator stops immediately by the earthquake. It also minimizes the nuclear waste problem by reducing the amount of the toxic waste and shortening their half lifetime to only a few hundred years. Finally, it solves the Uranium reserve problem because it can use Thorium as its fuel. The Thorium reserve is much larger than that of Uranium. Although the idea of ADS was proposed long time ago, it has not been utilized yet first by technical difficulty of accelerator. The accelerator based system needs 1 GeV, 10 MW power proton beam, which is an unprecedentedly high power. The most powerful 1 GeV proton linear accelerator is the Spallation Neutron Source, USA, which operates now at the power of 1.5 MW with the length of 350 m. A conventional linear accelerator would need

    Prosthetic arm research predominantly focuses on "bionic" but not body-powered arms. However, any research orientation along user needs requires sufficiently precise workplace specifications and sufficiently hard testing. Forensic medicine is a demanding environment, also physically, also for non-disabled people, on several dimensions (e.g., distances, weights, size, temperature, time). As unilateral below elbow amputee user, the first author is in a unique position to provide direct comparison of a "bionic" myoelectric iLimb Revolution (Touch Bionics) and a customized body-powered arm which contains a number of new developments initiated or developed by the user: (1) quick lock steel wrist unit; (2) cable mount modification; (3) cast shape modeled shoulder anchor; (4) suspension with a soft double layer liner (Ohio Willowwood) and tube gauze (Molnlycke) combination. The iLimb is mounted on an epoxy socket; a lanyard fixed liner (Ohio Willowwood) contains magnetic electrodes (Liberating Technologies). An on the job usage of five years was supplemented with dedicated and focused intensive two-week use tests at work for both systems. The side-by-side comparison showed that the customized body-powered arm provides reliable, comfortable, effective, powerful as well as subtle service with minimal maintenance; most notably, grip reliability, grip force regulation, grip performance, center of balance, component wear down, sweat/temperature independence and skin state are good whereas the iLimb system exhibited a number of relevant serious constraints. Research and development of functional prostheses may want to focus on body-powered technology as it already performs on manually demanding and heavy jobs whereas eliminating myoelectric technology's constraints seems out of reach. Relevant testing could be developed to help expediting this. This is relevant as Swiss disability insurance specifically supports prostheses that enable actual work integration. Myoelectric and

    Physicochemical characterization of olive mill wastewaters (OMW) was studied after a primary and secondary treatment was implemented in an olive oil factory in Jaén (Spain), comprising natural precipitation, Fenton-like reaction, flocculation-sedimentation and olive stone filtration in series. The application of membrane technology in improving the quality of the secondary-treated OMW (OMW/ST) was examined, to reduce the hazardous electroconductivity (EC) values (2-3 mS cm(-1)). Particle size distribution on OMW/ST shows supra-micron colloids and suspended solids as well as sub-micron particles with a mean size below 1.5 μm remaining in considerable concentration. The high organic pollutants percentage (31.7%) registered with an average diameter below 3 kDa is sensibly relevant for membrane fouling. Mesophilic aerobic bacteria growth warns of possible membrane biofouling formation. The saturation index indicates to work upon recovery factor below 90%. Finally, operating at a pressure equal to 15 bar ensured low fouling and high flux production on the selected NF membrane (69.9 L h(-1)m(-2)) and significant rejection efficiencies (55.5% and 88.5% for EC and COD). This permits obtaining an effluent with good quality according to the recommendations of the Food and Agricultural Association (FAO) with the goal of reusing the regenerated water for irrigation.

  17. Bio-plastic (poly-hydroxy-alkanoate) production from municipal sewage sludge in the Netherlands: a technology push or a demand driven process?

    Science.gov (United States)

    Bluemink, E D; van Nieuwenhuijzen, A F; Wypkema, E; Uijterlinde, C A

    Valorisation of components from municipal 'waste' water and sewage sludge gets more and more attention in order to come to a circular economy by developing an efficient 'waste' to value concept. On behalf of the transition team 'Grondstoffenfabriek' ('Resource factory') a preliminary research was performed for all the Dutch water boards to assess the technical and economical feasibility of poly-hydroxy-alkanoate (PHA)-production from sewage sludge, a valuable product to produce bio-plastics. This study reveals that the production of bio-plastics from sewage sludge is feasible based on technical aspects, but not yet economically interesting, even though the selling price is relatively close to the actual PHA market price. (Selling price is in this particular case the indicative cost effective selling price. The cost effective selling price covers only the total production costs of the product.) Future process optimization (maximizing the volatile fatty acids production, PHA storage capacity, etc.) and market developments are needed and will result in cost reductions of the various sub-processes. PHA-production from sewage sludge at this stage is just a technology; every further research is needed to incorporate the backward integration approach, taking into account the market demand including associated product quality aspects.

    Full Text Available This study attempted to measure forest resources at the individual tree level using high-resolution images by combining GPS, RS, and Geographic Information System (GIS technologies. The images were acquired by the WorldView-2 satellite with a resolution of 0.5 m in the panchromatic band and 2.0 m in the multispectral bands. Field data of 90 plots were used to verify the interpreted accuracy. The tops of trees in three groups, namely ≥10 cm, ≥15 cm, and ≥20 cm DBH (diameter at breast height, were extracted by the individual tree crown (ITC approach using filters with moving windows of 3 × 3 pixels, 5 × 5 pixels and 7 × 7 pixels, respectively. In the study area, there were 1,203,970 trees of DBH over 10 cm, and the interpreted accuracy was 73.68 ± 15.14% averaged over the 90 plots. The numbers of the trees that were ≥15 cm and ≥20 cm DBH were 727,887 and 548,919, with an average accuracy of 68.74 ± 17.21% and 71.92 ± 18.03%, respectively. The pixel-based classification showed that the classified accuracies of the 16 classes obtained using the eight multispectral bands were higher than those obtained using only the four standard bands. The increments ranged from 0.1% for the water class to 17.0% for Metasequoia glyptostroboides, with an average value of 4.8% for the 16 classes. In addition, to overcome the “mixed pixels” problem, a crown-based supervised classification, which can improve the classified accuracy of both dominant species and smaller classes, was used for generating a thematic map of tree species. The improvements of the crown- to pixel-based classification ranged from −1.6% for the open forest class to 34.3% for Metasequoia glyptostroboides, with an average value of 20.3% for the 10 classes. All tree tops were then annotated with the species attributes from the map, and a tree count of different species indicated that the forest of Purple Mountain is mainly dominated by Quercus acutissima, Liquidambar formosana

    In spite of all advances in research on the social forming of technology, there are still many unresolved questions. This applies especially to innovations in new fields of engineering, especially key technologies and interdisciplinary technologies which today are conceivable only as processes of distributed, interdisciplinary technology development. Microsystem technology is discussed here as an example: On the one hand, the author analyzes the mechanisms by which independent actors tune their activities so that high-tech development becomes possible in the first place. On the other hand, he raises the question how the actors, in the course of technology development, change social conditions more or less systematically. The summed-up discussion of these questions provides a concept of technology development as a process of institutionalisation. The author's theoretical interest is in the types and preconditions of developing commitment to action. The empirical analysis also provides a contribution to a theory of the emergence of social and cognitive structuring. (orig.)

    2014-01-01

    To be habitable, a world (planet or moon) does not need to be located in the stellar habitable zone (HZ), and worlds in the HZ are not necessarily habitable. Here, we illustrate how tidal heating can render terrestrial or icy worlds habitable beyond the stellar HZ. Scientists have developed a language that neglects the possible existence of worlds that offer more benign environments to life than Earth does. We call these objects "superhabitable" and discuss in which contexts this term could be used, that is to say, which worlds tend to be more habitable than Earth. In an appendix, we show why the principle of mediocracy cannot be used to logically explain why Earth should be a particularly habitable planet or why other inhabited worlds should be Earth-like. Superhabitable worlds must be considered for future follow-up observations of signs of extraterrestrial life. Considering a range of physical effects, we conclude that they will tend to be slightly older and more massive than Earth and that their host stars will likely be K dwarfs. This makes Alpha Centauri B, which is a member of the closest stellar system to the Sun and is supposed to host an Earth-mass planet, an ideal target for searches for a superhabitable world.

    The use of synchrotrons for pulsed neutron spallation sources is an example of scientific and technological spin-off from the accelerator development for particle physics. Accelerator-driven sources provide an alternative to the continuous-flux, nuclear reactors that currently furnish the majority of neutrons for research and development. Although the present demand for neutrons can be adequately met by the existing reactors, this situation is unlikely to continue due to the increasing severity of safety regulations and the declared policies of many countries to close down their reactors within the next decade or so. Since the demand for neutrons as a research tool is, in any case,expected to grow, there has been a corresponding interest in sources that are synchrotron-driven or linac-driven with a pulse compression ring and currently several design studies are being made. These accelerator-driven sources also have the advantage of a time structure with a high peak neutron flux. The basic requirement is for a...

    Full Text Available Seed quality will remain the centerpiece of successful agricultural programs in the year 2000. As new changes occur in agriculture driven by advancements in biotechnology, seed enhancement technologies, a more diverse seed user clientele, and communication technologies, successful seed companies will require a knowledgeable and informed workforce to assure high seed quality. A new approach to seed technology training is professed that relies on the establishment of a three-institution consortium to achieve this objective. Advantages of the consortium are identified that emphasize the unique strengths of each institution, their geographic advantages representing major climactic/agricultural zones in the world, and differing approaches to seed technology training that are facilitated by increasing ease of global communication. This may be a better way to conduct seed technology training in the year 2000.

    Hansen, Hans Nørgaard; Alting, Leo

    2004-01-01

    The use of micro and nano technologies in components and products not only sets new demands to the manufacturing technologies. Product concepts have to be rethought and redefined in order to implement the micro and nano technologies into functional systems. Both a technology driven and a product...... driven approach can be used in this process. A framework for the product driven approach in nano manufacturing is presented and discussed. The general discussion will be supported by case studies covering polymers and metals....

    2017-07-01

    This report provides a preliminary (three month) analysis for the SolarWorld system installed at the New Mexico Regional Test Center (RTC.) The 8.7kW, four-string system consists of four module types): bifacial, mono-crystalline, mono-crystalline glass-glass and polycrystalline. Overall, the SolarWorld system has performed well to date: most strings closely match their specification-sheet module temperature coefficients and Sandia 's f lash tests show that Pmax values are well within expectations. Although the polycrystalline modules underperformed, the results may be a function of light exposure, as well as mismatch within the string, and not a production flaw. The instantaneous bifacial gains for SolarWorld 's Bisun modules were modest but it should be noted that the RTC racking is not optimized for bifacial modules, nor is albedo optimized at the site. Additional analysis, not only of the SolarWorld installation in New Mexico but of the SolarWorld installations at the Vermont and Florida RTCs will be provide much more information regarding the comparative performance of the four module types.

  1. Laser-driven particle and photon beams and some applications

    International Nuclear Information System (INIS)

    Ledingham, K W D; Galster, W

    2010-01-01

    Outstanding progress has been made in high-power laser technology in the last 10 years with laser powers reaching petawatt (PW) values. At present, there are 15 PW lasers built or being built around the world and plans are afoot for new, even higher power, lasers reaching values of exawatt (EW) or even zetawatt (ZW) powers. Petawatt lasers generate electric fields of 10 12 V m -1 with a large fraction of the total pulse energy being converted to relativistic electrons with energies reaching in excess of 1 GeV. In turn these electrons result in the generation of beams of protons, heavy ions, neutrons and high-energy photons. These laser-driven particle beams have encouraged many to think of carrying out experiments normally associated with conventional nuclear accelerators and reactors. To this end a number of introductory articles have been written under a trial name 'Laser Nuclear Physics' (Ledingham and Norreys 1999 Contemp. Phys. 40 367, Ledingham et al 2002 Europhys. News. 33 120, Ledingham et al 2003 Science 300 1107, Takabe et al 2001 J. Plasma Fusion Res. 77 1094). However, even greater strides have been made in the last 3 or 4 years in laser technology and it is timely to reassess the potential of laser-driven particle and photon beams. It must be acknowledged right from the outset that to date laser-driven particle beams have yet to compete favourably with conventional nuclear accelerator-generated beams in any way and so this is not a paper comparing laser and conventional accelerators. However, occasionally throughout the paper as a reality check, it will be mentioned what conventional nuclear accelerators can do.

    An educational program of study can be viewed as a knowledge graph consisting of learning units and relationships between them. Such a knowledge graph provides the core data structure for organizing and navigating learning experiences. We address three issues in this talk. First, how can we synthesize the knowledge graph, given a set of concepts to be covered in the study program. Next, how can we use data mining to identify and correct deficiencies in a knowledge graph. Finally, how can we use data mining to form study groups with the goal of maximizing overall learning. We conclude by pointing out some open research problems.   BIOGRAPHY OF RAKESH AGRAWAL Rakesh Agrawal is the President and Founder of the Data Insights Laboratories, San Jose, USA.

    Early successes in identifying and targeting individual oncogenic drivers, together with the increasing feasibility of sequencing tumor genomes, have brought forth the promise of genome-driven oncology care. As we expand the breadth and depth of genomic analyses, the biological and clinical complexity of its implementation will be unparalleled. Challenges include target credentialing and validation, implementing drug combinations, clinical trial designs, targeting tumor heterogeneity, and deploying technologies beyond DNA sequencing, among others. We review how contemporary approaches are tackling these challenges and will ultimately serve as an engine for biological discovery and increase our insight into cancer and its treatment.

    If a society decides to make use of the advantages of technologies that at the same time bear extensive potentials of harm, society has to prevent abuse of these potentials. Physical protection and other security measures inevitably entail a curtailment of personal liberty. The civil rights will not provide sufficient protection against such creeping loss of personal freedom. The high priority of the objects of legal protection in question will make it necessary to specify the civil rights according to conditions if the security measures are to become effective in practice. Weighing the legal merits and the principle of reasonableness will be the main instruments that will pave the way for a camouflaged change of legal concepts and, finally, a factual restriction of civil rights. Any policy of law intended to protect the civil rights therefore will have to clain responsible participation in research activities, technological development, and energy policy. The policy of law has to take care that the criterion of compatibility with the constitution, the weakening or strengthening effect of a technological system on the civil rights, will duly be taken into account in the process of democratic technology steering, and as early as possible.

  14. The Center for Environmental Technology Innovative Technology Screening Process

    International Nuclear Information System (INIS)

    Bertrand, C.M.

    1995-02-01

    The Center for Environmental Technology's (CET) mission is to provide a fully integrated system for accelerated evaluation, development, commercialization, and public acceptance of creative environmental solutions which match the foremost demands in today's environmentally sensitive world. In short, CET will create a means to provide quick, effective solutions for environmental needs. To meet this mission objective, CET has created a unique and innovative approach to eliminating the usual barriers in developing and testing environmental technologies. The approach paves the way for these emerging, cutting-edge technologies by coordinating environmental restoration and waste management activities of industry, universities, and the government to: efficiently and effectively transfer technology to these users, provide market-driven, cost-effective technology programs to the public and DOE, and aid in developing innovative ideas by initiating efforts between DOE facilities and private industry. The central part to this mission is selecting and evaluating specific innovative technologies for demonstration and application at United States Department of Energy (DOE) installations. The methodology and criteria used for this selection, which is called the CET Innovative Technology Screening Process, is the subject of this paper. The selection criteria used for the screening process were modeled after other DOE technology transfer programs and were further developed by CET's Technology Screening and Evaluation Board (TSEB). The process benefits both CET and the proposing vendors by providing objective selection procedures based on predefined criteria. The selection process ensures a rapid response to proposing vendors, all technologies will have the opportunity to enter the selection process, and all technologies are evaluated on the same scale and with identical criteria

    2017-01-01

    Full Text Available We describe and reflect on three case studies of developing fieldwork for tertiary students of architectural history, landscape history and urban design. In each case, the potential of blended learning was explored through the use of mobile technology to explore designated sites as extensions of class-based learning. Two studies involved the development of apps that worked as guides for students to explore places of significance in Melbourne, while one study invited students to develop a design for a mobile app that could communicate the influence of urban design thinkers on a particular place in Sydney. We describe how these three exercises provide insights into the way that mobile technology, both real and imagined, can provide a conduit between classroom and field learning. Equally significant, we reflect on how the process of designing the apps became one of extended co-creation between student, tutors and teaching staff, also with consequence for learning.

    Hansen, L.F.; Maniscalco, J.A.

    1977-11-01

    The role of the fusion-fission hybrid reactor (FFHR) as a fissile fuel and/or power producer is discussed. As long range options to supply the world energy needs, hybrid-fueled thermal-burner reactors are compared to liquid metal fast breeder reactors (LMFBR). A discussion of different fuel cycles (thorium, depleted uranium, and spent fuel) is presented in order to compare the energy multiplication, the production of fissile fuel, the laser efficiency and pellet gain requirements of the hybrid reactor. Lawrence Livermore Laboratory (LLL) has collaborated with Bechtel Corporation and with Westinghouse in two engineering design studies of laser fusion driven hybrid power plants. The hybrid designs which have resulted from these two studies are briefly described and analyzed by considering operational parameters, such as energy multiplication, power density, burn-up and plutonium production as a function time

    International Nuclear Information System (INIS)

    Connolly, T.J.; Hansen, U.; Jaek, W.; Beckurts, K.H.

    1979-01-01

    In examing the world nuclear energy paths, the following assumptions were adopted: the world economy will grow somewhat more slowly than in the past, leading to reductions in electricity demand growth rates; national and international political impediments to the deployment of nuclear power will gradually disappear over the next few years; further development of nuclear power will proceed steadily, without serious interruption but with realistic lead times for the introduction of advanced technologies. Given these assumptions, this paper attempts a study of possible world nuclear energy developments, disaggregated on a regional and national basis. The scenario technique was used and a few alternative fuel-cycle scenarios were developed. Each is an internally consistent model of technically and economically feasible paths to the further development of nuclear power in an aggregate of individual countries and regions of the world. The main purpose of this modeling exercise was to gain some insight into the probable international locations of reactors and other nuclear facilities, the future requirements for uranium and for fuel-cycle services, and the problems of spent-fuel storage and waste management. The study also presents an assessment of the role that nuclear power might actually play in meeting future world energy demand

    Regenerative medicine (RM) is a fascinating area of research and innovation. The huge potential of the field has been fairly underexploited so far. Both TERMIS-AM and TERMIS-EU Industry Committees are committed to mentoring and training young entrepreneurs for more successful commercial translation of upstream research. With this objective in mind, the two entities jointly organized an industry symposium during the past TERMIS World Congress (Boston, September 8-11, 2015) and invited senior managers of the RM industry for lectures and panel discussions. One of the two sessions of the symposium-How to overcome obstacles encountered when bringing products to the commercial phase?-aimed to share the inside, real experiences of leaders from TEI Biosciences (an Integra Company), Vericel (formerly Aastrom; acquirer of Genzyme Regenerative Medicine assets), RegenMedTX (formerly Tengion), Mindset Rx, ViThera Pharmaceuticals, and L'Oreal Research & Innovation. The symposium provided practical recommendations for RM product development, for remaining critical and objective when reviewing progress, for keeping solutions simple, and for remaining relevant and persistent.

  11. Typical worlds

    Barrett, Jeffrey A.

    2017-05-01

    Hugh Everett III presented pure wave mechanics, sometimes referred to as the many-worlds interpretation, as a solution to the quantum measurement problem. While pure wave mechanics is an objectively deterministic physical theory with no probabilities, Everett sought to show how the theory might be understood as making the standard quantum statistical predictions as appearances to observers who were themselves described by the theory. We will consider his argument and how it depends on a particular notion of branch typicality. We will also consider responses to Everett and the relationship between typicality and probability. The suggestion will be that pure wave mechanics requires a number of significant auxiliary assumptions in order to make anything like the standard quantum predictions.

    The traditional concept of terraforming assumes ready availability of candidate planets with acceptable qualities: orbiting a star in its "Goldilocks zone", liquid water, enough mass, years longer than days, magnetic field, etc. But even stipulating affordable interstellar travel, we still might never find a good candidate elsewhere. Whatever we found likely would require centuries of heavy terraforming, just as Mars or Venus would here. Our increasing appreciation of the ubiquity of life suggests that any terra nova would already possess it. We would then face the dilemma of introducing alien life forms (us, our microbes) into another living world. Instead, we propose a novel method to create habitable environments for humanity by enclosing airless, sterile, otherwise useless planets, moons, and even large asteroids within engineered shells, which avoids the conundrum. These shells are subject to two opposing internal stresses: compression due to the primary's gravity, and tension from atmospheric pressure contained inside. By careful design, these two cancel each other resulting in zero net shell stress. Beneath the shell an Earth-like environment could be created similar in almost all respects to that of Home, except for gravity, regardless of the distance to the sun or other star. Englobing a small planet, moon, or even a dwarf planet like Ceres, would require astronomical amounts of material (quadrillions of tons) and energy, plus a great deal of time. It would be a quantum leap in difficulty over building Dyson Dots or industrializing our solar system, perhaps comparable to a mission across interstellar space with a living crew within their lifetime. But when accomplished, these constructs would be complete (albeit small) worlds, not merely large habitats. They could be stable across historic timescales, possibly geologic. Each would contain a full, self-sustaining ecology, which might evolve in curious directions over time. This has interesting implications

    Original estimates stated that the amount of radioactive waste that will be generated during the dismantling of the Tokamak Fusion Test Reactor will approach two million kilograms with an associated volume of 2,500 cubic meters. The materials were activated by 14 MeV neutrons and were highly contaminated with tritium, which present unique challenges to maintain integrity during packaging and transportation. In addition, the majority of this material is stainless steel and copper structural metal that were specifically designed and manufactured for this one-of-a-kind fusion research reactor. This provided further complexity in planning and managing the waste. We will discuss the engineering concepts, innovative practices, and technologies that were utilized to size reduce, stabilize, and package the many unique and complex components of this reactor. This waste was packaged and shipped in many different configurations and methods according to the transportation regulations and disposal facility requirements. For this particular project, we were able to utilize two separate disposal facilities for burial. This paper will conclude with a complete summary of the actual results of the waste management costs, volumes, and best practices that were developed from this groundbreaking and successful project

    2015-05-01

    The requirement to detect hazardous materials (i.e., chemical, biological, and explosive) on a host of materials has led to the development of hazard detection systems. These new technologies and their capabilities could have immediate uses for the US military, national security agencies, and environmental response teams in efforts to keep people secure and safe. In particular, due to the increasing use by terrorists, the detection of common explosives and improvised explosive device (IED) materials have motivated research efforts toward detecting trace (i.e., particle level) quantities on multiple commonly encountered surfaces (e.g., textiles, metals, plastics, natural products, and even people). Non-destructive detection techniques can detect trace quantities of explosive materials; however, it can be challenging in the presence of a complex chemical background. One spectroscopic technique gaining increased attention for detection is Raman. One popular explosive precursor material is ammonium nitrate (AN). The material AN has many agricultural applications, however it can also be used in the fabrication of IEDs or homemade explosives (HMEs). In this paper, known amounts of AN will be deposited using an inkjet printer into several different common material surfaces (e.g., wood, human hair, textiles, metals, plastics). The materials are characterized with microscope images and by collecting Raman spectral data. In this report the detection and identification of AN will be demonstrated.

    1992-01-01

    As an introduction to this special issue 'Worlds of difference: Scenarios's for the economy, energy and the environment 1990-2015', an outline is given of the future of the world and the Netherlands, based on four scenarios. These scenarios are published in 'Scanning the future' in May 1992 by the CPB, the Dutch Central Planning Bureau. The Global Shift (GS) scenario is characterized by a very dynamic technological development, the free market perspective, strong economic growth in the Asian economies, and a relative economic regression in Western Europe. In the European Renaissance (ER) scenario the technological development is less dynamic and more gradual than in the GS scenario. The Balanced Growth (BG) scenario is dominated by a sustainable economic development and a strong technological dynamic development. The Global Crisis (GC) scenario shows a downward spiral in many areas, stagnating developments and fragile economies as results of the trends in the eighties. The first three scenarios are elaborated for the Netherlands. Also attention is paid to the aims and meaning of long-term scenarios. 2 figs., 2 tabs., 3 refs

  18. Militarism and world health.

    Science.gov (United States)

    Kiefer, C W

    1992-04-01

    Militarism is a rapidly growing factor in that complex network of social, political and economic causes of ill health among the world's poor. This complex of causes is driving a spiral of class inequality, political instability, and military repression in many less developed nations. These nations share a uniform security doctrine, which has major health impacts. Here five impacts are noted: diversion of resources, suppression of dissent, military classism, environment damage, and crime and terrorism. The demand stimulated by the recent Persian Gulf War for expensive, high-technology weapons may deepen Third World debt and fuel the cycle of poverty, ill health, social unrest, and military oppression. International health workers need to take account of the causes and effects of militarism in their studies of health problems. Their work could be aided by organizations that promote disarmament and environment preservation.

  4. Deploying Embodied AI into Virtual Worlds

    Science.gov (United States)

    Burden, David J. H.

    The last two years have seen the start of commercial activity within virtual worlds. Unlike computer games where Non-Player-Character avatars are common, in most virtual worlds they are the exception — and until recently in Second Life they were non-existent. However there is real commercial scope for Als in these worlds — in roles from virtual sales staff and tutors to personal assistants. Deploying an embodied AI into a virtual world offers a unique opportunity to evaluate embodied Als, and to develop them within an environment where human and computer are on almost equal terms. This paper presents an architecture being used for the deployment of chatbot driven avatars within the Second Life virtual world, looks at the challenges of deploying an AI within such a virtual world, the possible implications for the Turing Test, and identifies research directions for the future.

    2017-06-01

    As a litany of worlds gently tug on the stars around us, we are driven to build instruments that can discern the smallest stellar motions and reveal this population of planets. However, the path to extreme precision spectroscopy, required to detect Earth-like planets, is a difficult one that must be forged from technological and scientific discovery. Anchored by the success of HARPS and other precision spectrographs in the field, we are moving into the development of complete radial velocity systems that are capable of detecting small signatures in both the optical and near-infrared. I will discuss two such instruments being developed at Penn State: (a) the Habitable Zone Planet Finder, a NIR spectrograph for the 10m Hobby-Eberly Telescope, and (b) NEID, an extreme precision optical instrument which is the cornerstone of the NN-EXPLORE partnership. The science enabled by these instruments will be far-reaching, ranging from immediate follow-up of close-in TESS and K2 candidates, to identifying potentially well-separated targets for future space missions such as WFIRST-AFTA, HabEx or LUVOIR, and providing new insight into the hitherto unexplored connections between populaces of inner and outer solar systems.

    In this paper, are presented some possibilities concerning the implementation of a test-driven development as a programming method. Here is offered a different point of view for creation of advanced programming techniques (build tests before programming source with all necessary software tools and modules respectively). Therefore, this nontraditional approach for easier programmer's work through building tests at first is preferable way of software development. This approach allows comparatively simple programming (applied with different object-oriented programming languages as for example JAVA, XML, PYTHON etc.). It is predictable way to develop software tools and to provide help about creating better software that is also easier to maintain. Test-driven programming is able to replace more complicated casual paradigms, used by many programmers.

    In this work we present a model for evolving networks, where the driven force is related to the social affinity between individuals of a population. In the model, a set of individuals initially arranged on a regular ordered network and thus linked with their closest neighbors are allowed to rearrange their connections according to a dynamics closely related to that of the stable marriage problem. We show that the behavior of some topological properties of the resulting networks follows a non trivial pattern.

  13. Virtual Worlds for Virtual Organizing

    Science.gov (United States)

    Rhoten, Diana; Lutters, Wayne

    The members and resources of a virtual organization are dispersed across time and space, yet they function as a coherent entity through the use of technologies, networks, and alliances. As virtual organizations proliferate and become increasingly important in society, many may exploit the technical architecture s of virtual worlds, which are the confluence of computer-mediated communication, telepresence, and virtual reality originally created for gaming. A brief socio-technical history describes their early origins and the waves of progress followed by stasis that brought us to the current period of renewed enthusiasm. Examination of contemporary examples demonstrates how three genres of virtual worlds have enabled new arenas for virtual organizing: developer-defined closed worlds, user-modifiable quasi-open worlds, and user-generated open worlds. Among expected future trends are an increase in collaboration born virtually rather than imported from existing organizations, a tension between high-fidelity recreations of the physical world and hyper-stylized imaginations of fantasy worlds, and the growth of specialized worlds optimized for particular sectors, companies, or cultures.

    Research into recommendation algorithms has made great strides in recent years. However, these algorithms are typically applied in relatively straightforward scenarios: given information about a user's past preferences, what will they like in the future? Recommendation is often more complex......: evaluating recommended items never takes place in a vacuum, and it is often a single step in the user's more complex background task. In this paper, we define a specific type of recommendation scenario called narrative-driven recommendation, where the recommendation process is driven by both a log...... of the user's past transactions as well as a narrative description of their current interest(s). Through an analysis of a set of real-world recommendation narratives from the LibraryThing forums, we demonstrate the uniqueness and richness of this scenario and highlight common patterns and properties...

    This report forms part of a project entitled 'World Biofuels Study'. The objective is to study world biofuel markets and to examine the possible contribution that biofuel imports could make to help meet the Renewable Fuel Standard (RFS) of the Energy Independence and Security Act of 2007 (EISA). The study was sponsored by the Biomass Program of the Assistant Secretary for Energy Efficiency and Renewable Energy (EERE), U.S. Department of Energy. It is a collaborative effort among the Office of Policy and International Affairs (PI), Department of Energy and Oak Ridge National Laboratory (ORNL), National Renewable Energy Laboratory (NREL) and Brookhaven National Laboratory (BNL). The project consisted of three main components: (1) Assessment of the resource potential for biofuel feedstocks such as sugarcane, grains, soybean, palm oil and lignocellulosic crops and development of supply curves (ORNL). (2) Assessment of the cost and performance of biofuel production technologies (NREL). (3) Scenario-based analysis of world biofuel markets using the ETP global energy model with data developed in the first parts of the study (BNL). This report covers the modeling and analysis part of the project conducted by BNL in cooperation with PI. The Energy Technology Perspectives (ETP) energy system model was used as the analytical tool for this study. ETP is a 15 region global model designed using the MARKAL framework. MARKAL-based models are partial equilibrium models that incorporate a description of the physical energy system and provide a bottom-up approach to study the entire energy system. ETP was updated for this study with biomass resource data and biofuel production technology cost and performance data developed by ORNL and NREL under Tasks 1 and 2 of this project. Many countries around the world are embarking on ambitious biofuel policies through renewable fuel standards and economic incentives. As a result, the global biofuel demand is expected to grow very

The ``Constructive Technology Assessment/CTA`` approach in the social science debate on technology; Gutachten zum Thema TA als theoriegeleitete Interventionsstrategie. Der Ansatz des ``Constructive Technology Assessment/CTA`` in der sozialwissenschaftlichen Technikdebatte

    Energy Technology Data Exchange (ETDEWEB)

    Hack, L.

    1995-11-01

    Using theoretical motives of the new sociology of scientific knowledge (SSK) social sciences have developed a new kind of handling technology. `Success of technology` is no longer self-evident, but it has to be explained; that a technology `works` is not (only) a matter of engineering, but (also) the result of social constructions. The borderline between `technology` and `society` cannot be taken as an ontological phenomenon, it rather has to be grasped as outcome of always changing forms and procedures of demarcation. On these foundations there has been built the approach of the so-called `Constructive Technology Assessment (CTA)` which is meant to open up possibilities for a pragmatic manner in the societal and political shaping of technological developments. TA is now conceived as a social learning-process; technological developments are seen as highly complex processes, taking place in the frame of strategic games. On the background of such empirical topics and corresponding practical experiences, there have been developed new strategies of theorizing, which aim at an `endogenous theory of the emergence of cognitive and social structurations`. It is rather obvious, that there are shortcomings (eclecticism) in the basic theoretical conceptions; but there cannot be any doubt that, by using CTA, there is made science policy in a very skillful manner - especially by opening up a new entrance for the societal handling (shaping) of technology. Power structures are theoretically underexposed, but they are taken quite seriously for practical purposes. (orig.) [Deutsch] In Aufnahme theoretischer Argumente aus der neueren Soziologie wissenschaftlichen Wissens hat sich das sozialwissenschaftliche Verstaendis von Technik grundlegend geaendert.

  3. Globalization's effects on world agricultural trade, 1960-2050.

    Science.gov (United States)

    Anderson, Kym

    2010-09-27

    Recent globalization has been characterized by a decline in the costs of cross-border trade in farm and other products. It has been driven primarily by the information and communication technology revolution and-in the case of farm products-by reductions in governmental distortions to agricultural production, consumption and trade. Both have boosted economic growth and reduced poverty globally, especially in Asia. The first but maybe not the second of these drivers will continue in coming decades. World food prices will depend also on whether (and if so by how much) farm productivity growth continues to outpace demand growth and to what extent diets in emerging economies move towards livestock and horticultural products at the expense of staples. Demand in turn will be driven not only by population and income growth, but also by crude oil prices if they remain at current historically high levels, since that will affect biofuel demand. Climate change mitigation policies and adaptation, water market developments and market access standards particularly for transgenic foods will add to future production, price and trade uncertainties.

    Recent globalization has been characterized by a decline in the costs of cross-border trade in farm and other products. It has been driven primarily by the information and communication technology revolution and—in the case of farm products—by reductions in governmental distortions to agricultural production, consumption and trade. Both have boosted economic growth and reduced poverty globally, especially in Asia. The first but maybe not the second of these drivers will continue in coming decades. World food prices will depend also on whether (and if so by how much) farm productivity growth continues to outpace demand growth and to what extent diets in emerging economies move towards livestock and horticultural products at the expense of staples. Demand in turn will be driven not only by population and income growth, but also by crude oil prices if they remain at current historically high levels, since that will affect biofuel demand. Climate change mitigation policies and adaptation, water market developments and market access standards particularly for transgenic foods will add to future production, price and trade uncertainties.

    Accelerator-driven systems for fissile materials production have been proposed and studied since the early 1950s. Recent advances in beam power levels for small accelerators have raised the possibility that such use could be feasible for a potential proliferator. The objective of this study is to review the state of technology development for accelerator-driven spallation neutron sources and subcritical reactors. Energy and power requirements were calculated for a proton accelerator-driven neutron spallation source and subcritical reactors to produce a significant amount of fissile material--plutonium

    Projections of global total energy and electrical energy consumption rates based on Stewart's model of cycle-adjusted-logistic growth are presented and discussed. Time intervals required for supply and demand in the US fluid fuels sector to balance are estimated. The provisional global energy projection for the coming decade is one of low growth rates accompanied by economic adjustments and difficulties and falling energy prices. The projection for the first quarter of the twenty-first century reflects a cyclic reversal to sharply increased economic activity, energy demands, fuel prices, and pressure on the technological sector to provide an adequate energy supply. Implications for the developing nations and for the US and world economies are briefly addressed.

    Actions to be taken in order to better control the developments in the world can be divided in general actions (birth control and polemology), short or medium term actions (<20 years), and long term actions (>20 years). Resources in the world (knowledge, skilled manpower, energy and finances) are limited. A clean environment has to be included in the world's resources. Our present resources can hardly meet the legitimate demands of a world population of eight billion people. In order to create acceptable conditions for survival in all areas in the world, social education should lead, via birth control and responsible parenthood, to a stabilization of the world population of 8 billion people. A better understanding of the basic causes of international conflicts is needed. Therefore the activities of existing global and regional institutes on polemology should be strengthened. Energy conservation is a must. Through optimization and combination of (energy)cycles another 25% savings can be achieved. Deep conservation through a change of lifestyle can be realized by taxes on the use of energy or through reduction of income. Given the present resources and taking into account the available technology, nuclear energy has to be included in the world energy scene. The nuclear option requests strict international control on operation and waste management. Transfer of resources should be based on a global strategy. Resources should be activated in those areas of the world where they will be most effective. Given the limited resources in the world, long term actions should be based on international cooperation through existing bodies. 5 figs., 4 refs.

    1998-01-01

    World Wide Web (W3) technologies such as the Hypertext Transfer Protocol (HTTP) and the Java object-oriented programming environment offer a powerful, yet relatively inexpensive, framework for distributed application software development. This paper describes the design of a real-time payload control and monitoring system that was developed with W3 technologies at NASA Ames Research Center. Based on Java Development Toolkit (JDK) 1.1, the system uses an event-driven "publish and subscribe" approach to inter-process communication and graphical user-interface construction. A C Language Integrated Production System (CLIPS) compatible inference engine provides the back-end intelligent data processing capability, while Oracle Relational Database Management System (RDBMS) provides the data management function. Preliminary evaluation shows acceptable performance for some classes of payloads, with Java's portability and multimedia support identified as the most significant benefit.

In light of these constraints, the notion that subduction is the main driver of present–day Pacific plate motion becomes somewhat unviable, as the pulling force that would be required by slabs exceeds the maximum available from......The Pacific plate is thought to be driven mainly by slab pull, associated with subduction along the Aleutians–Japan, Marianas–Izu–Bonin and Tonga–Kermadec trenches. This implies that viscous flow within the sub–Pacific asthenosphere is mainly generated by overlying plate motion (i.e. Couette flow......), and that the associated shear–stresses at the lithosphere's base are resisting such motion. Recent studies on glacial isostatic adjustment and lithosphere dynamics provide tighter constraints on the viscosity and thickness of Earth's asthenosphere and, therefore, on the amount of shear–stress that asthenosphere...

    Angiogenesis is a multiscale process by which blood vessels grow from existing ones and carry oxygen to distant organs. Angiogenesis is essential for normal organ growth and wounded tissue repair but it may also be induced by tumours to amplify their own growth. Mathematical and computational models contribute to understanding angiogenesis and developing anti-angiogenic drugs, but most work only involves numerical simulations and analysis has lagged. A recent stochastic model of tumour-induced angiogenesis including blood vessel branching, elongation, and anastomosis captures some of its intrinsic multiscale structures, yet allows one to extract a deterministic integropartial differential description of the vessel tip density. Here we find that the latter advances chemotactically towards the tumour driven by a soliton (similar to the famous Korteweg-de Vries soliton) whose shape and velocity change slowly. Analysing these collective coordinates paves the way for controlling angiogenesis through the soliton, the engine that drives this process.

    The goal of the MDA is to produce software systems from abstract models in a way where human interaction is restricted to a minimum. These abstract models are based on the UML language. However, the semantics of UML models is defined in a natural language. Subsequently the verification of consistency of these diagrams is needed in order to identify errors in requirements at the early stage of the development process. The verification of consistency is difficult due to a semi-formal nature of UML diagrams. We propose automatic verification of consistency of the series of UML diagrams originating from abstract models implemented with our consistency rules. This Consistent Model Driven Architecture approach enables us to generate automatically complete workflow applications from consistent and complete models developed from abstract models (e.g. Business Context Diagram). Therefore, our method can be used to check practicability (feasibility) of software architecture models.

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

    The European Event on Technology (EET), a recurrent annual event since 1992, is a major meeting opportunity for researchers and engineers as well as private and public decision-makers, on technologies, their evolution and their industrial and social implications. In less than a decade, sustainable development has become both an economic and a political priority. It was urgent and legitimate that those who are the mainsprings should take hold of the subject and give it technological content, estimate its costs and define clear timetables. The debates consist of: plenary sessions on environmental, social and economic stakes of sustainable development and the challenges for, and commitment of engineers, managers and politicians with respect to these goals; and workshops, which provide an overview of recently acquired or upcoming technologies developed by sector: energy, transports, new information technologies, new industrial manufacturing technologies (materials, products, services), waste management, global environment monitoring, water management, bio-technologies, and innovation management. This document brings together the different talks given by the participants. Among these, the following ones fall into the energy and environment scope: energy efficiency of buildings: towards energy autonomy; superconductors enable in new millennium for electric power industry; advanced gas micro-turbine-driven generator technology; environmental and technical challenges of an offshore wind farm; future nuclear energy systems; modelling combustion in engines: progress and prospects for reducing emissions; on-board computers: reduction in consumption and emissions of engine-transmission units for vehicles; polymer-lithium batteries: perspectives for zero-emission traction; hybrid vehicles and energy/environmental optimization: paths and opportunities; fuel cells and zero-emission: perspectives and developments; global change: causes, modeling and economic issues; the GMES

    Evaporation is a ubiquitous phenomenon in the natural environment and a dominant form of energy transfer in the Earth's climate. Engineered systems rarely, if ever, use evaporation as a source of energy, despite myriad examples of such adaptations in the biological world. Here, we report evaporation-driven engines that can power common tasks like locomotion and electricity generation. These engines start and run autonomously when placed at air-water interfaces. They generate rotary and piston-like linear motion using specially designed, biologically based artificial muscles responsive to moisture fluctuations. Using these engines, we demonstrate an electricity generator that rests on water while harvesting its evaporation to power a light source, and a miniature car (weighing 0.1 kg) that moves forward as the water in the car evaporates. Evaporation-driven engines may find applications in powering robotic systems, sensors, devices and machinery that function in the natural environment.

    2006-11-07

    The 2008 report provides invaluable analysis to help policy makers around the world assess and address the challenges posed by worsening oil supply prospects, higher energy prices and rising emissions of greenhouse gases. In the WEO-2008 Reference Scenario, which assumes no new government policies, world primary energy demand grows by 1.6% per year on average between 2006 and 2030 - an increase of 45%. This is slower than projected last year, mainly due to the impact of the economic slowdown, prospects for higher energy prices and some new policy initiatives. Demand for oil rises from 85 million barrels per day now to 106 mb/d in 2030 - 10 mb/d less than projected last year. Demand for coal rises more than any other fuel in absolute terms, accounting for over a third of the increase in energy use. Modern renewables grow most rapidly, overtaking gas to become the second-largest source of electricity soon after 2010. China and India account for over half of incremental energy demand to 2030 while the Middle East emerges as a major new demand centre. The share of the world's energy consumed in cities grows from two-thirds to almost three-quarters in 2030. Almost all of the increase in fossil-energy production occurs in non-OECD countries. These trends call for energy-supply investment of $26.3 trillion to 2030, or over 1 trillion US dollars/year. Yet the credit squeeze could delay spending, potentially setting up a supply-crunch that could choke economic recovery. In addition to providing a comprehensive update of long-term energy projections to 2030, WEO-2008 takes a detailed look at the prospects for oil and gas production. Oil will remain the world's main source of energy for many years to come, even under the most optimistic of assumptions about the development of alternative technology. But the sources of oil, the cost of producing it and the prices that consumers will have to pay for it are extremely uncertain. It is far from certain that companies

    Driven by an economic growth of 3.2%, world energy demand could grow by about 1.7%/year by 2030, according to the IEA (WEO 2004), representing a global increase of almost 60% over 2002. Fossil fuels, which meet more than 80% of world primary energy needs, will continue to play a major role, as they are abundant and well adapted to various uses. Already underway for more than a decade, energy diversification in favour of gas will continue, stimulated by the need for using more environment-friendly sources of energy. (author)

    Educators and commenters who evaluate big data-driven learning environments focus on specific questions: whether automated education platforms improve learning outcomes, invade student privacy, and promote equality. This article puts aside separate unresolved-and perhaps unresolvable-issues regarding the concrete effects of specific technologies. It instead examines how big data-driven tools alter the structure of schools' pedagogical decision-making, and, in doing so, change fundamental aspects of America's education enterprise. Technological mediation and data-driven decision-making have a particularly significant impact in learning environments because the education process primarily consists of dynamic information exchange. In this overview, I highlight three significant structural shifts that accompany school reliance on data-driven instructional platforms that perform core school functions: teaching, assessment, and credentialing. First, virtual learning environments create information technology infrastructures featuring constant data collection, continuous algorithmic assessment, and possibly infinite record retention. This undermines the traditional intellectual privacy and safety of classrooms. Second, these systems displace pedagogical decision-making from educators serving public interests to private, often for-profit, technology providers. They constrain teachers' academic autonomy, obscure student evaluation, and reduce parents' and students' ability to participate or challenge education decision-making. Third, big data-driven tools define what "counts" as education by mapping the concepts, creating the content, determining the metrics, and setting desired learning outcomes of instruction. These shifts cede important decision-making to private entities without public scrutiny or pedagogical examination. In contrast to the public and heated debates that accompany textbook choices, schools often adopt education technologies ad hoc. Given education

    1997-01-01

    This paper presents the methodology used in the ETSU review, together with the detailed results for three of the technologies studied: wind turbines, photovoltaic systems and small, stand-alone solar thermal systems. These emissions are then compared with those calculated for both other renewables and fossil fuel technology on a similar life cycle basis. The life cycle emissions associated with renewable energy technology vary considerably. They are lowest for those technologies where the renewable resource has been concentrated in some way (e.g. over distance in the case of wind and hydro, or over time in the case of energy crops). Wind turbines have amongst the lowest emissions of all renewables and are lower than those for fossil fuel generation, often by over an order of magnitude. Photovoltaics and solar thermal systems have the highest life cycle emissions of all the renewable energy technologies under review. However, their emissions of most pollutants are also much lower than those associated with fossil fuel technologies. In addition, the emissions associated with PV are likely to fall further in the future as the conversion efficiency of PV cells increases and manufacturing technology switches to thin film technologies, which are less energy intensive. Combining the assessments of life cycle emissions of renewables with predictions made by the World Energy Council (WEC) of their future deployment has allowed estimates to be made of amount by which renewables could reduce the future global emissions of carbon dioxide, sulphur dioxide and nitrogen oxides. It estimated that under the WEC's 'Ecologically Driven' scenario, renewables might lead to significant reductions of between 3650 and 8375 Mt in annual CO 2 emissions depending on the fossil fuel technology they are assumed to displace.

    Ontario Hydro's customer-driven strategy, recently approved by Hydro's Executive Board, was described. The strategy is founded on the following components: (1) the dissolution of the Ontario power pool, i.e., the loss of Hydro's franchise monopoly on generation, leaving only power transmission in the hands of the Corporation, (2) divestment of Ontario Hydro's system operations and market operations functions to a new, independent Crown corporation called the Central Market Operator, (3) functional and organizational unbundling of Ontario Hydro into three signature businesses, Genco, Transco, and Retailco, and in the latter two, the functional unbundling of wires from sales and services, (4) a fully commercial Ontario Hydro with normal corporate powers, and (5) a corporate strategy for Ontario Hydro to grow in businesses in an open, symmetrical North American energy market. According to Ontario Hydro management this will allow competition and choice to all customers, have a disciplining effect on prices, and give rise to a retail market of new products and services, while at the same time preserve and enhance the value of public investment in the Corporation

    As the world population is ageing, studies on the socio-economic and health consequences are proliferating. Little has been done on the effectiveness and impact elderly may benefit from the use of technology in their everyday life. The pilot study, implemented within a funded project aimed at identifying sustainable actions to promote Seniors' quality of life, intended to investigate this kind of interaction in terms of accessibility and acceptability that senior citizen experience with technological devices promoting motor and cognitive training. In the hypothesis, interfaces and technological artifacts, that still take in little account the seniors' physical characteristics (e.g. physiological limitations in sight, hearing, movement) and cognitive processes (selective memory often driven by practical needs), can cause elderly to mistrust technology. Study participants were twenty over seventy-year-old people, who were observed and interviewed in context in a two-hour training session regarding the technological devices user experience. The results are presented with scenario-based techniques that help represent typologies of users in different use situations. Findings confirm the hypothesis, highlighting that elderly may accept technological artifacts when they perceive them as bringing benefits in terms of well-being and health.

    Critical thinking and scientific reasoning are central to higher education in the United States, but many courses (in-person and online) teach students information about science much more than they teach the actual process of science and its associated knowledge and skills. In the online arena specifically, the tools available for course construction exacerbate this problem by making it difficult to build the types of active learning activities that research shows to be the most effective. Here, we present a report on Habitable Worlds, offered by Arizona State University for 12 semesters over the past 6 years. This is a unique online course that uses an array of novel technologies to deliver an active, inquiry-driven learning experience. Learning outcomes and quantitative data from more than 3000 students demonstrate the success of our approach but also identify several remaining challenges. The design and development of this course offers valuable lessons for instructional designers and educators who are interested in fully capitalizing on the capabilities of 21st-century technology to achieve educational goals.

    Full Text Available Amid unprecedented growth in access to information communication technologies (ICTs, particularly in the developing world, how can international actors, governments, and civil society organizations leverage ICTs and the data they generate to more effectively prevent violence and conflict? New research shows that there is huge potential for innovative technologies to inform conflict prevention efforts, particularly when technology is used to help information flow horizontally between citizens and when it is integrated into existing civil society initiatives.1 However, new technologies are not a panacea for preventing and reducing violence and conflict. In fact, failure to consider the possible knock-on effects of applying a specific technology can lead to fatal outcomes in violent settings. In addition, employing new technologies for conflict prevention can produce very different results depending on the context in which they are applied and whether or not those using the technology take that context into account. This is particularly true in light of the dramatic changes underway in the landscapes of violence and conflict on a global level. As such, instead of focusing on supply-driven technical fixes, those undertaking prevention initiatives should let the context inform what kind of technology is needed and what kind of approach will work best.

    World View of Global Warming is an independent photojournalistic documentation of global warming and rapid climate change begun in 1999. The intended outcomes of the work - the photographs, reportage and publications - are based on the principles of scientific accuracy, a journalistic approach, strong photographic skills, long-term observations, science literacy, education, documentation for policy makers and inspiration to others. During the course of this project the team of photojournalist and public health toxicologist visited, interviewed and/or had correspondence with more than 150 scientists in the field on every continent. Hundreds more have influenced and informed the work. World View of Global Warming has tested the idea that climate change can be more easily understood by the public and government officials through photographs which accurately and engagingly depict the locations and the scientists involved in research, communities responding to impacts of climate change and innovations for mitigation. Use of the photographs by scientists to further their own work and outreach was an immediate and continuing result, including use in journals, reports, textbooks and conferences. This presentation will demonstrate the many uses of photography in climate change communications and discuss how scientists and educators can more effectively interact with the public and media and artists. The website for this project was established in 2002 and now has more than 100 pages of photographs and information. It is strictly non-commercial and documented. Wide and repeated publication indicates the value of the project's climate communication: Exhibition at the Boston Museum of Science (2013), the National Academy of Sciences and the American Assn. for the Advancement of Science and other venues; extended use by the United Nations, UNFCCC, World Meteorological Organization, Environmental Protection Agency and the Office of Science and Technology Policy in the Executive

    Availability and utilization of energy and water are the top most global challenges being faced by the new millennium. At the present state water scarcity has become a global as well as a regional challenge. 40 % of world population faces water shortage. Challenge of water scarcity can be tackled only with increase in water supply beyond what is obtained from hydrological cycle. This can be achieved either by desalinating the sea water or by reusing the waste water. High energy requirement need to be overcome for either of the two processes. Of many desalination technologies, humidification dehumidification (HDH) technology powered by solar energy is widely accepted for small scale production. Detailed optimization studies on system have the potential to effectively utilize the solar energy for brackish water desalination. Dehumidification technology, specifically, require further study because the dehumidifier effectiveness control the energetic performance of the entire HDH system. The reason attributes to the high resistance involved to diffuse dilute vapor through air in a dehumidifier. The present work intends to optimize the design of a bubble column dehumidifier for a solar energy driven desalination process. Optimization is carried out using Matlab simulation. Design process will identify the unique needs of a bubble column dehumidifier in HDH system.
