    The theory that natural selection is the key to adaptive evolution, and the reasoning for his conclusions, were Darwin's contributions to science. However, only half of Americans accept the fact of evolution as true (Gallup, 2008). Walsh contends that there are three reasons that students today find life's existential struggle less apparent.…

    In all OECD countries, digital media and connectedness are integral to the lives of todays learners. It is often claimed that these learners are ""new millennium learners"", or ""digital natives"", who have different expectations about education. This book contributes to the debate about the effects of technology attachment and connectedness on todays learners, and their expectations about teaching. The book sets out to answer the following questions: Can the claim that todays students are ""new millenium learners"" or ""digital natives be sustained empirically? Is there consistent research evidence demonstrating the effects of technology on cognitive development, social values, and learning expectations? What are the implications for educational policy and practice?

    To keep in tune with the rapidly changing 'Hardware' technology, it is imperative that all of the supporting components of a program's efforts reflect these increases in technology. To maintain a work force that keeps in tune with the ever increasing technology base, training needs to remain a major consideration in all types of organizations. This paper focuses on the area of training and education and suggests a reasonable, cost effective alternative to carrying the entire burden of developing, training and maintaining a workforce in a rapidly changing, highly technological environment.

    Lantern slides will keep a long time, which is a good quality for preservation. However, as I have found, they break. Unless there is a lantern slide projector available, there is no way to show these valuable assets to others. This poster will explain my project to bring these pictures to life, to use them in education projects, and to simply show a bit of history to an attentive audience. With today's technology they can be placed on computers and stored more easily and be a joy to all.

    2009-05-01

    Reverse osmosis membrane technology has developed over the past 40 years to a 44% share in world desalting production capacity, and an 80% share in the total number of desalination plants installed worldwide. The use of membrane desalination has increased as materials have improved and costs have decreased. Today, reverse osmosis membranes are the leading technology for new desalination installations, and they are applied to a variety of salt water resources using tailored pretreatment and membrane system design. Two distinct branches of reverse osmosis desalination have emerged: seawater reverse osmosis and brackish water reverse osmosis. Differences between the two water sources, including foulants, salinity, waste brine (concentrate) disposal options, and plant location, have created significant differences in process development, implementation, and key technical problems. Pretreatment options are similar for both types of reverse osmosis and depend on the specific components of the water source. Both brackish water and seawater reverse osmosis (RO) will continue to be used worldwide; new technology in energy recovery and renewable energy, as well as innovative plant design, will allow greater use of desalination for inland and rural communities, while providing more affordable water for large coastal cities. A wide variety of research and general information on RO desalination is available; however, a direct comparison of seawater and brackish water RO systems is necessary to highlight similarities and differences in process development. This article brings to light key parameters of an RO process and process modifications due to feed water characteristics.

  11. Compilation of Existing Neutron Screen Technology

    Full Text Available The presence of fast neutron spectra in new reactors is expected to induce a strong impact on the contained materials, including structural materials, nuclear fuels, neutron reflecting materials, and tritium breeding materials. Therefore, introduction of these reactors into operation will require extensive testing of their components, which must be performed under neutronic conditions representative of those expected to prevail inside the reactor cores when in operation. Due to limited availability of fast reactors, testing of future reactor materials will mostly take place in water cooled material test reactors (MTRs by tailoring the neutron spectrum via neutron screens. The latter rely on the utilization of materials capable of absorbing neutrons at specific energy. A large but fragmented experience is available on that topic. In this work a comprehensive compilation of the existing neutron screen technology is attempted, focusing on neutron screens developed in order to locally enhance the fast over thermal neutron flux ratio in a reactor core.

  14. The “healthy immigrant” effect: does it exist in Europe today?

    Directory of Open Access Journals (Sweden)

    2012-09-01

    Full Text Available Several studies, carried out mainly in the United States and Canada, have suggested that recent immigrants are generally healthier than native-born populations in spite of the fact that they frequently have a lower socioeconomic status and less access to healthcare services. This “epidemiological paradox” has been called the “healthy immigrant” effect and is usually attributed to a self-selection process prior to migration, “cultural buffering” and official health screening and employability in receiving countries. In this paper, we have evaluated the European scientific research into the existence of the “healthy immigrant” effect.

  15. On the existence and stability of liquid water on the surface of mars today

    Science.gov (United States)

    Kuznetz, L. H.; Gan, D. C.

    2002-01-01

    The recent discovery of high concentrations of hydrogen just below the surface of Mars' polar regions by Mars Odyssey has enlivened the debate about past or present life on Mars. The prevailing assumption prior to the discovery was that the liquid water essential for its existence is absent. That assumption was based largely on the calculation of heat and mass transfer coefficients or theoretical climate models. This research uses an experimental approach to determine the feasibility of liquid water under martian conditions, setting the stage for a more empirical approach to the question of life on Mars. Experiments were conducted in three parts: Liquid water's existence was confirmed by droplets observed under martian conditions in part 1; the evolution of frost melting on the surface of various rocks under martian conditions was observed in part 2; and the evaporation rate of water in Petri dishes under Mars-like conditions was determined and compared with the theoretical predictions of various investigators in part 3. The results led to the conclusion that liquid water can be stable for extended periods of time on the martian surface under present-day conditions.

    The Department of Energy`s clean coal technology (CCT) program succeeded in developing more efficient, cleaner, coal-fired electricity options. The Department and its private partners succeeded in the demonstration of CCT -- a major feat that required more than a decade of commitment between them. As with many large-scale capital developments and changes, the market can shift dramatically over the course of the development process. The CCT program was undertaken in an era of unstable oil and gas prices, concern over acid rain, and guaranteed markets for power suppliers. Regulations, fuel prices, emergency of competing technologies, and institutional factors are all affecting the outlook for CCT deployment. The authors identify the major barriers to CCT deployment and then introduce some possible means to surmount the barriers.

    The Energetic X-ray Imaging Survey Telescope (EXIST) is a proposed very large area coded aperture telescope array, incorporating 8m^2 of pixellated Cd-Zn-Te (CZT) detectors, to conduct a full-sky imaging and temporal hard x-ray (10-600 keV) survey each 95min orbit. With a sensitivity (5sigma, 1yr) of ~0.05mCrab (10-150 keV), it will extend the ROSAT soft x-ray (0.5-2.5keV) and proposed ROSITA medium x-ray (2-10 keV) surveys into the hard x-ray band and enable identification and study of sources ~10-20X fainter than with the ~15-100keV survey planned for the upcoming Swift mission. At ~100-600 keV, the ~1mCrab sensitivity is 300X that achieved in the only previous (HEAO-A4, non-imaging) all-sky survey. EXIST will address a broad range of key science objectives: from obscured AGN and surveys for black holes on all scales, which constrain the accretion history of the universe, to the highest sensitivity and resolution studies of gamma-ray bursts it will conduct as the Next Generation Gamma-Ray Burst mission.

    electronic manual that contains all the required data and illustrations in expanded view format using standard PC products (Word, Excel, PDF, Photoshop). The logistics of accurately releasing this information to field personnel was greatly enhanced via the utilization of common office products to produce a more user-friendly format than was originally developed under contract to NASA. This was done without reinventing the system, which would be cost prohibitive on a program of this maturity. The brunt of the joint part tracking is done within the logistics organization and disseminated to all field sites, without duplicating effort at each site. The JDL is easily accessible across the country via the NASA intranet directly at the SSME workstand. The advent of this logistics data product has greatly enhanced the reliability of tracking dynamic changes to the SSME and greatly reduces engineering change turnaround time and potential for errors. Since the inception of the JDL system in 1997, no discrepant parts have propagated to engine assembly operations. This presentation focuses on the challenges overcome and the techniques used to apply today's desktop technologies to an existing logistics data source.

  2. Recent Life Assessment Technology for Existing Steam Turbines

    Science.gov (United States)

    Saito, Kiyoshi; Sakuma, Akira; Fukuda, Masataka

    A large and growing portion of electricity is produced by aging thermal power plants. Although excellent, high quality materials such as CrMoV steel and 12% Cr steel, etc. are used for the steam turbines, various forms of metallurgical degradation, due to creep and fatigue, etc. affect the parts and components during long-term operation at high temperature. Extending the life of steam turbines and ensuring high reliability requires life assessment technology, scheduled repairing, conversion, modification and upgrading of components in order to provide a stable power supply. As the high temperature parts and components of aged steam turbines are mainly metallurgically damaged by creep, fatigue and the interaction of both, life assessment combined with analytical and nondestructive methods is essential for realizing strategic plant life extension. We have developed a life assessment technology that takes material degradation into consideration, and have applied the procedure to more than 650 units and 2500 components since 1983. A rotor bore replication device was developed in 1989 for the purpose of nondestructive observation of creep voids and supporting the validity of life prediction results. This paper describes the technical features and applied experience of recent life assessment technology for existing high temperature steam turbines.

    2006-05-09

    The performance of an advanced Microhole Coiled Tubing Rig (MCTR) has been measured in the field during the drilling of 25 test wells in the Niobrara formation of Western Kansas and Eastern Colorado. The coiled tubing (CT) rig designed, built and operated by Advanced Drilling Technologies (ADT), was documented in its performance by GTI staff in the course of drilling wells ranging in depth from 500 to nearly 3,000 feet. Access to well sites in the Niobrara for documenting CT rig performance was provided by Rosewood Resources of Arlington, VA. The ADT CT rig was selected for field performance evaluation because it is one of the most advanced commercial CT rig designs that demonstrate a high degree of process integration and ease of set-up and operation. Employing an information collection protocol, data was collected from the ADT CT rig during 25 drilling events that encompassed a wide range of depths and drilling conditions in the Niobrara. Information collected included time-function data, selected parametric information indicating CT rig operational conditions, staffing levels, and field observations of the CT rig in each phase of operation, from rig up to rig down. The data obtained in this field evaluation indicates that the ADT CT rig exhibited excellent performance in the drilling and completion of more than 25 wells in the Niobrara under varied drilling depths and formation conditions. In the majority of the 25 project well drilling events, ROP values ranged between 300 and 620 feet per hour. For all but the lowest 2 wells, ROP values averaged approximately 400 feet per hour, representing an excellent drilling capability. Most wells of depths between 500 and 2,000 feet were drilled at a total functional rig time of less than 16 hours; for wells as deep at 2,500 to 3,000 feet, the total rig time for the CT unit is usually well under one day. About 40-55 percent of the functional rig time is divided evenly between drilling and casing/cementing. The balance of

    As in some domestic nuclear power plants, spent fuel pools near capacity, away-from-reactor type storage should be arranged to transfer spent fuel before the pool capacity is full and the plants can operate in safety. This study compares the features of wet and dry storage technology, analyzes the actualities of foreign dry storage facilities and then introduces structural characteristics of some foreign dry storage cask. Finally, a glance will be cast on the failure of away-from-reactor storage facilities of Pressurized Water Reactor(PWR)to meet the need of spent-fuel storage. Therefore, this study believes dry storage will be a feasible solution to the problem.

The advantages and disadvantages of these approaches are shown. Determine the scope of their application. It is shown that the hierarchy analysis method works well with the full initial information, but due to the need for expert comparison of alternatives and the selection of evaluation criteria has a high proportion of subjectivity. For problems in the conditions of risk and uncertainty prediction seems reasonable use of the theory of fuzzy sets and neural networks. It is also considered technology collective decision applied both in the general election, and the group of experts. It reduces the time for conciliation meetings to reach a consensus by the preliminary analysis of all views submitted for the plane in the form of points. At the same time the consistency of opinion is determined by the distance between them.

Even though we had some positive results, the utilization of these tools doesn’t seem to significantly reduce weaker student’s difficulties. These students need stronger support to motivate them to get engaged in learning activities, inside and outside classroom. Nowadays, many technologies are available to create contexts that may help to accomplish this goal. We consider that a promising path goes through the integration of solutions. In this paper we analyze the features, strengths and weaknesses of the tools developed by our group. Based on these considerations we present a new environment, integrating different types of pedagogical approaches, resources, tools and technologies for programming learning support. With this environment, currently under development, it will be possible to review contents and lessons, based on video and screen captures. The support for collaborative tasks is another key point to improve and stimulate different models of teamwork. The platform will also allow the creation of various alternative models (learning objects for the same subject, enabling personalized learning paths adapted to each student knowledge level, needs and preferential learning styles. The learning sequences will work as a study organizer, following a suitable taxonomy, according to student’s cognitive skills. Although the main goal of this environment is to support students with more difficulties, it will provide a set of resources supporting the learning of more advanced topics. Software engineering techniques and representations, object orientation and event programming are features that will be available in order to promote the learning progress of students.

    The majority of the feed-in tariffs as determined by the German Energy Feed-in Act (EEG) develop as follows: they decrease as the efficiency of technologies grows. However, there are some exceptions: offshore wind and geothermal energy feed-in tariffs have been rising, while storage technologies are not included at all although they are needed to make up for intermittent renewable generation. Furthermore, nuclear energy is burdened with the fuel tax, a kind of negative feed-in tariff. These technologies seem to be confronted with specific restrictions that yet prevent large-scale development. A thorough analysis of these limitations guides to the way to overcome them.

  1. Psychoanalysis today

    FONAGY, PETER

    2003-01-01

    The paper discusses the precarious position of psychoanalysis, a therapeutic approach which historically has defined itself by freedom from constraint and counted treatment length not in terms of number of sessions but in terms of years, in today's era of empirically validated treatments and brief structured interventions. The evidence that exists for the effectiveness of psychoanalysis as a treatment for psychological disorder is reviewed. The evidence base is significant and growing, but less than might meet criteria for an empirically based therapy. The author goes on to argue that the absence of evidence may be symptomatic of the epistemic difficulties that psychoanalysis faces in the context of 21st century psychiatry, and examines some of the philosophical problems faced by psychoanalysis as a model of the mind. Finally some changes necessary in order to ensure a future for psychoanalysis and psychoanalytic therapies within psychiatry are suggested. PMID:16946899

PFS is generally a good predictor of OS for cases where survival post-progression (SPP is short, and less so when SPP is long. SPP depends on multiple factors, including residual effect from experimental treatment and effect from crossover or other subsequent therapies, posing unique challenges into the translation of PFS benefit into OS. Methods: The objective of this analysis was to conduct simulations investigating how increasing SPP impacts PFS translation to OS, utilizing data from the AXIS (axitinib versus sorafenib in advanced metastatic renal cell carcinoma trial. The underlying assumption was a treatment benefit in PFS (the PFS distribution parameters were chosen to be equal to median PFS in the AXIS trial but no treatment effect on SPP, implying that PFS improvement is directly reflected in OS improvement. Results: The probability of a statistically significant difference between arms for OS decreased from 54.7% to 6.1% when median SPP was increased from one to 20 months. The probability of the hazard ratio of OS being ≥0.9 was similarly increased from 24.3% to 72.6%, even though the hazard ratio for PFS was 0.69. Conclusion: The present study shows that when simulated SPP is added to trial PFS data, the existing PFS benefit is diluted. Knowing that the AXIS treatment arms are well balanced with respect to post-trial treatments, we conclude that the PFS to OS benefit translation is primarily

    Svilicić, Niksa; Vidacković, Zlatko

    2013-03-01

    This paper seeks to explain some of the most important recent production and technological changes that have affected the relationship between television and film, especially in Croatia, from the aspect of the development of visual anthropology. In the production segment, special attention was given to the role of Croatian television stations in the production of movies, "splitting" the movies into mini-series, interrupting movies with commercial breaks, and to television movies turned into feature films. This paper tries to perceive and define the structure of methodical processes of visual anthropology (reactive process). The development of photographic and film technology and the events which led to the rapid development of visual culture also point to the inseparable duality of observing visual anthropology within reactive and proactive processes, which are indirectly closely related to the technical aspects of these processes. Defining the technical aspect of visual anthropology as such "service" necessarily interferes with the author's approach in the domain of the script and direction related procedures during pre-production, on the field and during post-production of the movie. The author's approach is important because in dependence on it, the desired spectrum of information "output", susceptible to subsequent scientific analysis, is achieved. Lastly, another important segment is the "distributive-technological process" because, regardless of the approach to the anthropologically relevant phenomenon which is being dealt with in an audio-visual piece of work, it is essential that the work be presented and viewed adequately.

    This book disentangles the issues in connection with the advancement of Health Technology Assessment (HTA) and its interface with health policy. It highlights the factors that should shape its progress in the near future. Interdisciplinary and critical views from a number of professionals are put together in a prescient order to cast some light and make recommendations as to the next steps HTA should take to be fit for purpose. A wealth of documents dealing with HTA have been published over the last three decades. HTA allegedly is one of the bedrocks of regulation and medical decision making. However, counter vailing visions contend that geographical variations in the role that HTA is actually playing within countries pinpoints specific room for improvement. Given our social preferences, cherry-picking HTA's features and successes over the last decades moves it away from its possibility frontier. Some of the most noteworthy hindrances that HTA faces, in several countries, to making headway towards its consoli...

    NASA's Students' Cloud Observations On-Line (S'COOL) project, a hands-on educational project, was an innovative idea conceived by the scientists in the Radiation Sciences Branch at NASA Langley Research Center, Hampton, Virginia, in 1996. It came about after a local teacher expressed the idea that she wanted her students to be involved in real-life science. S'COOL supports NASA's Clouds and the Earth's Radiant Energy System (CERES) instrument, which was launched on the Tropical Rainforest Measuring Mission (TRMM) in November, 1997, as part of NASA's Earth Science Enterprise. With the S'COOL project students observe clouds and related weather conditions, compute data and note vital information while obtaining ground truth observations for the CERES instrument. The observations can then be used to help validate the CERES measurements, particularly detection of clear sky from space. In addition to meeting math, science and geography standards, students are engaged in using the computer to obtain, report and analyze current data, thus bringing modern technology into the realm of classroom, a paradigm that demands our attention.

    1990-09-01

    As the clinical laboratory advances toward total automation, the marketplace is now demanding more-efficient sample-handling systems. These demands have arisen over a relatively short period of time, in part because of heightened concern over laboratory safety and the resulting manpower shortages. Adding sample-handling capabilities to existing instrumentation is often a challenge, because usually mechanical or system constraints are present that interfere. This challenge has been overcome in the DuPont Sample Management System (SMS), a second-generation general chemistry analyzer that incorporates the latest barcode and computer-interfacing technology. The development of the SMS system relies heavily on recent advances in technology, e.g., software modeling and computer-aided design. The SMS system includes a barcode scanner based on "charge-coupled device" technology, a random-access sample wheel, and new software that oversees the various functions.

    Full Text Available Abstract Bracing is the main non-surgical intervention in the treatment of idiopathic scoliosis during growth, in hyperkyphosis (and Scheuermann disease and occasionally for spondylolisthesis; it can be used in adult scoliosis, in the elderly when pathological curves lead to a forward leaning posture or in adults after traumatic injuries. Bracing can be defined as the application of external corrective forces to the trunk; rigid supports or elastic bands can be used and braces can be custom-made or prefabricated. The state of research in the field of conservative treatment is insufficient and while it can be stated that there is some evidence to support bracing, we must also acknowledge that today we do not have a common and generally accepted knowledge base, and that instead, individual expertise still prevails, giving rise to different schools of thought on brace construction and principles of correction. The only way to improve the knowledge and understanding of brace type and brace function is to establish a single and comprehensive source of information about bracing. This is what the Scoliosis Journal is going to do through the "Brace Technology" Thematic Series, where technical papers coming from the different schools will be published.

    2014-09-01

    Building science research supports installing exterior (soil side) foundation insulation as the optimal method to enhance the hygrothermal performance of new homes. With exterior foundation insulation, water management strategies are maximized while insulating the basement space and ensuring a more even temperature at the foundation wall. This project describes an innovative, minimally invasive foundation insulation upgrade technique on an existing home that uses hydrovac excavation technology combined with a liquid insulating foam. Cost savings over the traditional excavation process ranged from 23% to 50%. The excavationless process could result in even greater savings since replacement of building structures, exterior features, utility meters, and landscaping would be minimal or non-existent in an excavationless process.

    Environmental impacts of conventional and emerging perchlorate drinking water treatment technologies were assessed using life cycle assessment (LCA). Comparison of two ion exchange (IX) technologies (i.e., nonselective IX with periodic regeneration using brines and perchlorate-selective IX without regeneration) at an existing plant shows that brine is the dominant contributor for nonselective IX, which shows higher impact than perchlorate-selective IX. Resource consumption during the operational phase comprises >80% of the total impacts. Having identified consumables as the driving force behind environmental impacts, the relative environmental sustainability of IX, biological treatment, and catalytic reduction technologies are compared more generally using consumable inputs. The analysis indicates that the environmental impacts of heterotrophic biological treatment are 2-5 times more sensitive to influent conditions (i.e., nitrate/oxygen concentration) and are 3-14 times higher compared to IX. However, autotrophic biological treatment is most environmentally beneficial among all. Catalytic treatment using carbon-supported Re-Pd has a higher (ca. 4600 times) impact than others, but is within 0.9-30 times the impact of IX with a newly developed ligand-complexed Re-Pd catalyst formulation. This suggests catalytic reduction can be competitive with increased activity. Our assessment shows that while IX is an environmentally competitive, emerging technologies also show great promise from an environmental sustainability perspective.

    The Fission Energy and Systems Safety Program (FESSP) at LLNL was funded by the DOE Office of Safeguards and Security to develop an integrated system, hereafter referred to as the Security Clearance Electronic Processing, Transfer, Evaluation, and Recordkeeping (SCEPTER) System, for the electronic collection and transfer of personnel security data between clearance offices at contractor sites and DOE field offices and the Office of Personnel Management(OPM). This system will use existing software and hardware technologies where feasible. The project will consist of three phases. The first phase will investigate user needs, determine the feasibility of using existing technologies, and define project requirements. The second phase will be a pilot project to develop the computer systems and procedures required to automate the security clearance work flow within DOE and between DOE and OPM. Once the pilot system is implemented and tested, the decision to extend the system throughout DOE can be made. This third phase, the extension to a full production system, will require the investment of considerable funds in equipment and in the development of both a computer system and management infrastructure to support its successful operation. This investment will be undertaken only after the pilot system is operational and evaluated.

Investigation of the geological aspects of water regulation and irrigation as well as their impact on the environment. 6. Definition, examination and characterisation of the real soil forming geological sequence. In Hungary the actual agrogeological investigations were launched by the agricultural reambulation of geological mapping data. During the early 1980s the so-called BFK-method was elaborated to the agrogeological investigation of these areas still used today. The main aspect of this method is that apart from the common geological sampling of the boreholes samples are also taken from the top- and subsoil (horizon 1), the soil forming sediment or parent material (horizon 2), the fluctuation zone of the groundwater (horizon 3) as well as from the zone permanently below the groundwater level (horizon 4) and the groundwater itself (Figure 2). These samples undergo detailed laboratory analyses. The comparative evaluation of the derived results allows making different agrogeological conclusions. During the period elapsed from the early 1980s the survey of the pilot areas allowed us investigating among others the agrogeological relationships of salinisation, acidification, excess water risk, erosion, and trace element regime as well as vine chlorosis.

    In single-chamber solid oxide fuel cells (SC-SOFCs), both anode and cathode are situated in a common gas chamber and are exposed to a mixture of fuel and oxidant. The working principle is based on the difference in catalytic activity of the electrodes for the respective anodic and cathodic reactions. The resulting difference in oxygen partial pressure between the electrodes leads to the generation of an open circuit voltage. Progress in SC-SOFC technology has enabled the generation of power outputs comparable to those of conventional SOFCs. This paper provides a detailed review of the development of SC-SOFC technology.

    The paper explores the trend of the early 20th century to consolidate mathematics, natural sciences, medicine and technology under the umbrella of one integrative culture--a tendency which contrasts with the increasing mainstream trend of separating the humanities from the natural sciences. The unifying umbrella was framed by the great encyclopedia Die Kultur der Gegenwart which was published by B. G. Teubner from 1905 to 1925 and was planned to run up to 62 volumes. We analyze the quantitative rate of the parts devoted to the humanities, the natural sciences and technology, respectively, the degree to which these parts were completed in this encyclopedia. In particular, we investigate the role of mathematicians and their reasons to find a classification for the mathematical, natural scientific and engineering parts of culture as well as their reasons, to win Nobel prize winners and other famous scientists to become co-editors and authors. We examine the published volumes in the fields of mathematics, chemistry, physics, astronomy and technology in order to show what type of publication--professional or popular--was intended. Furthermore, we illuminate how the educational reform of mathematics, natural sciences and technology of this period--which included a reform of girls' and women's education--was reflected in the encyclopedia Die Kultur der Gegenwart.

    This paper reports on integrated watershed-based protection and sustainable use of water resources to increase the effectiveness of water pollution abatement. The approach includes improvements in end-of-pipe waste-water treatment technologies and implementation of Cleaner Production (CP) principles and policies within the watershed. An example of the general effectiveness of this approach is illustrated by the Czech Odra River Cleaner Production Project where reductions in pollution were achieved with improved industrial production. The CP theme is worth considering as an important challenge for the IWA.

    2005-01-01

    This quarterly report documents work performed under Tasks 10 through 14 of the project entitled: ''Technologies to Enhance Operation of the Existing Natural Gas Compression Infrastructure''. The project objective is to develop and substantiate methods for operating integral engine/compressors in gas pipeline service, which reduce fuel consumption, increase capacity, and enhance mechanical integrity. The report first documents tests performed on a KVG103 engine/compressor installed at Duke's Thomaston Compressor Station. This is the first series of tests performed on a four-stroke engine under this program. Additionally, this report presents results, which complete a comparison of performance before and after modification to install High Pressure Fuel Injection and a Turbocharger on a GMW10 at Williams Station 60. Quarterly Reports 7 and 8 already presented detailed data from tests before and after this modification, but the final quantitative comparison required some further analysis, which is presented in Section 5 of this report. The report further presents results of detailed geometrical measurements and flow bench testing performed on the cylinders and manifolds of the Laboratory Cooper GMVH6 engine being employed for two-stroke engine air balance investigations. These measurements are required to enhance the detailed accuracy in modeling the dynamic interaction of air manifold, exhaust manifold, and in-cylinder fuel-air balance.

  11. Use of multimedia technology to provide solutions to existing curriculum problems: Virtual frog dissection

    Science.gov (United States)

    Youngblut, Christine

    The objective of this research was to determine whether currently available multimedia technology can resolve existing problems in the K--12 science curriculum. There are several practical and ethical problems relating to the classroom use of animal dissection and this led to the selection of hands-on frog dissection as the curriculum activity where the use of multimedia was investigated. The major finding was that multimedia-based virtual dissection was more effective than hands-on dissection in helping students learn about frog anatomy. Moreover, this result was achieved when the time available for the virtual dissection was approximately 44% less than that available for hands-on dissection. Examination of possible relationships between student characteristics and achievement revealed that students' attitudes to educational uses of animal dissection and their computer experience were positively correlated with their achievement scores. No relationships were found between either student gender or dissection experience and achievement test outcomes. Students rated virtual dissection as the easier of the two types of dissection, though they gave equivalent ratings for their enjoyment of virtual and hands-on dissection. Despite favorable feedback on the virtual dissection, a significant majority of students stated that they felt they would be "missing-out" on a valuable experience if they were not given the opportunity to perform a hands-on frog dissection. Comparing how students spent their time during each type of dissection showed that students spent a significantly larger proportion of their time On-Task when using the multimedia-based virtual dissection. In particular, the average increase in the proportion of time spent on activities directly related to the subject matter was over 36%. Time spent On-Task had a significant positive relationship with achievement for hands-on dissection. It may play a similar role for achievement with virtual dissection, but the

    2007-05-01

    The goal of this project is to provide a technical review and evaluation of various carbon dioxide (CO{sub 2}) capture technologies, with a focus on the applicability to lignite-fired facilities within North Dakota. The motivation for the project came from the Lignite Energy Council's (LEC's) need to identify the feasibility of CO{sub 2} capture technologies for existing North Dakota lignite-fired, pulverized coal (pc) power plants. A literature review was completed to determine the commercially available technologies as well as to identify emerging CO{sub 2} capture technologies that are currently in the research or demonstration phase. The literature review revealed few commercially available technologies for a coal-fired power plant. CO{sub 2} separation and capture using amine scrubbing have been performed for several years in industry and could be applied to an existing pc-fired power plant. Other promising technologies do exist, but many are still in the research and demonstration phases. Oxyfuel combustion, a technology that has been used in industry for several years to increase boiler efficiency, is in the process of being tailored for CO{sub 2} separation and capture. These two technologies were chosen for evaluation for CO{sub 2} separation and capture from coal-fired power plants. Although oxyfuel combustion is still in the pilot-scale demonstration phase, it was chosen to be evaluated at LEC's request because it is one of the most promising emerging technologies. As part of the evaluation of the two chosen technologies, a conceptual design, a mass and energy balance, and an economic evaluation were completed.

    2006-05-31

    This project has documented and demonstrated the feasibility of technologies and operational choices for companies who operate the large installed fleet of integral engine compressors in pipeline service. Continued operations of this fleet is required to meet the projected growth of the U.S. gas market. Applying project results will meet the goals of the DOE-NETL Natural Gas Infrastructure program to enhance integrity, extend life, improve efficiency, and increase capacity, while managing NOx emissions. These benefits will translate into lower cost, more reliable gas transmission, and options for increasing deliverability from the existing infrastructure on high demand days. The power cylinders on large bore slow-speed integral engine/compressors do not in general combust equally. Variations in cylinder pressure between power cylinders occur cycle-to-cycle. These variations affect both individual cylinder performance and unit average performance. The magnitude of the variations in power cylinder combustion is dependent on a variety of parameters, including air/fuel ratio. Large variations in cylinder performance and peak firing pressure can lead to detonation and misfires, both of which can be damaging to the unit. Reducing the variation in combustion pressure, and moving the high and low performing cylinders closer to the mean is the goal of engine balancing. The benefit of improving the state of the engine ''balance'' is a small reduction in heat rate and a significant reduction in both crankshaft strain and emissions. A new method invented during the course of this project is combustion pressure ratio (CPR) balancing. This method is more effective than current methods because it naturally accounts for differences in compression pressure, which results from cylinder-to-cylinder differences in the amount of air flowing through the inlet ports and trapped at port closure. It also helps avoid compensation for low compression pressure by the

    Full Text Available We proposed a support system called the “Smart Partition System” for infill elements that integrate smart technologies according to the Open Building principles. The design requirements were collected from design practitioners. These design requirements consisted of both architectural and information subsystems. The Smart Partition System was composed of the following multiple levels of smartness: the foundation/core level with an embedded design knowledge in the support system and the utility level with a modular infill that integrate smart technologies. We constructed functional prototypes to demonstrate the feasibility of our proposed support system and some of the possibilities of the smart infill elements. Furthermore, the prototypes were evaluated by design practitioners. We compared our approach with current practices of smart building developments, and we also discussed some future prospects.

    2015-12-21

    This research project addresses one of the goals of the U.S. Department of Energy (DOE) Carbon Storage Program (CSP) aimed at developing Advanced Wellbore Integrity Technologies to Ensure Permanent Geologic Carbon Storage. The technology field-tested in this research project is referred to as microbially induced calcite precipitation (MICP), which utilizes a biologically-based process to precipitate calcium carbonate. If properly controlled MICP can successfully seal fractures, high permeability zones, and compromised wellbore cement in the vicinity of wellbores and in nearby caprock, thereby improving the storage security of geologically-stored carbon dioxide. This report describes an MICP sealing field test performed on a 24.4 cm (9.625 inch) diameter well located on the Gorgas Steam Generation facility near Jasper, Alabama. The research was aimed at (1) developing methods for delivering MICP promoting fluids downhole using conventional oil field technologies and (2) assessing the ability of MICP to seal cement and formation fractures in the near wellbore region in a sandstone formation. Both objectives were accomplished successfully during a field test performed during the period April 1-11, 2014. The test resulted in complete biomineralization sealing of a horizontal fracture located 340.7 m (1118 feet) below ground surface. A total of 24 calcium injections and six microbial inoculation injections were required over a three day period in order to achieve complete sealing. The fractured region was considered completely sealed when it was no longer possible to inject fluids into the formation without exceeding the initial formation fracture pressure. The test was accomplished using conventional oil field technology including an 11.4 L (3.0 gallon) wireline dump bailer for injecting the biomineralization materials downhole. Metrics indicating successful MICP sealing included reduced injectivity during seal formation, reduction in pressure falloff, and

    The United States Department of Health and Human Services (DHHS) has emphasized the importance of utilizing health information technologies, thus making the availability of electronic resources critical for physicians across the country. However, few empirical assessments exist regarding the current status of computerization and utilization of electronic resources in physician offices and physicians' perceptions of the advantages and disadvantages of computerization. Through a survey of physicians' utilization and perceptions of health information technology, this study found that a "digital divide" existed for eastern North Carolina physicians in smaller physician practices. The physicians in smaller practices were less likely to utilize or be interested in utilizing electronic health records, word processing applications, and the Internet.

  6. Increasing the Capacity of Existing Bridges by Using Unbonded Prestressing Technology: A Case Study

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available External posttensioning or unbonded prestressing was found to be a powerful tool for retrofitting and for increasing the life extension of existing structures. Since the 1950s, this technique of reinforcement was applied with success to bridge structures in many countries, and was found to provide an efficient and economic solution for a wide range of bridge types and conditions. Unbonded prestressing is defined as a system in which the post-tensioning tendons or bars are located outside the concrete cross-section and the prestressing forces are transmitted to the girder through the end anchorages, deviators, or saddles. In response to the demand for a faster and more efficient transportation system, there was a steady increase in the weight and volume of traffic throughout the world. Besides increases in legal vehicle loads, the overloading of vehicles is a common problem and it must also be considered when designing or assessing bridges. As a result, many bridges are now required to carry loads significantly greater than their original design loads; and their deck results still deteriorated by cracking of concrete, corrosion of rebars, snapping of tendons, and so forth. In the following, a case study about a railway bridge retrofitted by external posttensioning technique will be illustrated.

    2016-07-01

    Full Text Available The continuous world population growth induces a total protein demand increase based mainly on plant sources. To meet these global nutritional challenges, existing and innovative dry and wet fractionation processes will have to be combined to better valorise plant protein fraction from pulses and oilseeds. The worldwide success of soy protein isolates originate from the intrinsic qualities of soybean proteins but also from a continuous R&D effort since mid-twenty century. Therefore, the soy protein development model can be applied to protein isolates from diverse pulses and oilseeds meals as rapeseed which has already been recognised as novel food protein in Europe. To boost the delivery of plant proteins, agrofood-industries and academics must pool their respective expertise. Innovative and issue solving R&D projects have to be launched to better valorise pulses and oilseed proteins by (i creating oil extraction processes which preserve native proteins structure; (ii developing novel protein extraction processes from lab up to industrial pilot scale; (iii producing plant protein isolates having comparable foaming, emulsifying or gelling functionality than animal; and (iv generating hydrolysed proteins with high digestibility adapted to human nutrition. It is also essential to initiate research programs to innovate in wet and dry fractionations of plants or to design in vitro models to evaluate proteins digestibility and allergenicity. The increased awareness regarding plant protein valorisation resulted in the creation by agro-industries and academics of the open platform IMPROVE which propose a combination of competencies and equipment to boost market uptake of Plant Based Proteins.

    Improvement of the price/performance ratio of wind turbines is essential if wind energy is to be taken seriously in the world energy market in the coming century. The key to improvement of the price/performance ratio lies in the minimisation of loads by inexpensive means, at a simultaneous increase in annual production of the wind turbine. On basis of the NOVEM/CEC Flexhat project, this design project is a first step towards commercialisation of flexible rotor technology. The goal of the project was to redesign an existing stall-regulated wind turbine to improve the original price/performance ratio by 20%. This goal has been reached by the use of a larger, two-bladed rotor with elastomeric tester, variable speed drivetrain and fast active tip pitch control with an advanced peakshaving function. The project has been sponsored by the European Commission under contract nr. Jou2CT93-0281. (author)

  11. ProtoEXIST: balloon-borne technology development for wide-field hard X-ray imaging

    Science.gov (United States)

    Grindlay, Jonathan

    We report on the development of the ProtoEXIST balloon-borne experiment for development of wide-field coded aperture imaging with high spatial resolution imaging Cd-Zn-Te (CZT) arrays in close-tiled, large area configurations. ProtoEXIST1 will incorporate two coded aperture telescopes, each with 16 x 16cm close-tiled imaging CZT with 2.5mm pixels that maintain registration across the full detector. The detector plane incorporates new-technology low powered ASIC readout on each 20 x 20 x 5mm CZT crystal. A 2 x 4 array of such crystals are closetiled on a single board (DCA) with vertical integration to a controlling and readout-enabling FPGA. Detector readout modes can be commanded through the FPGA and selected in flight: from simple peak pixel, to peak plus neighbor pixels to larger pixel-selected modes, which will improve spatial/spectral resolution as well as allow for future tests of Compton imaging. The full readout consists of a 2 x 4 array of DCAs for each of the two telescopes. The detector plane is shielded from below by an active shield (2cm CsI) on one telescope vs. an equivalent graded-passive shield on the other to enable direct imaging comparisons of background rejection in a balloon environment. Both telescopes incorporate otherwise identical graded-passive side shields and laminated coded aperture masks (5mm pixels, laser-cut in W sheet). The telescopes each have 20o x 20o fields of view (FWHM), with 21arcmin resolution across the field. The ProtoEXIST gondola is derived from the old Harvard EXITE gondola but now with new pointing system and daytime star camera as developed at MSFC for the HERO balloon payload. A first flight is planned for September/October, 2008. Tests will include not only the first tests of this multipixel, controllable ASIC-readout system but also tests of the scanning coded aperture imaging as planned for the proposed EXIST mission. Followup flight(s) will test the higher-spatial resolution CZT imager (0.6mm pixels) now planned

    2010-07-01

    One manifestation of globalization is medical tourism. As its implications remain largely unknown, we reviewed claimed benefits and risks. Driven by high health-care costs, long waiting periods, or lack of access to new therapies in developed countries, most medical tourists (largely from the United States, Canada, and Western Europe) seek care in Asia and Latin America. Although individual patient risks may be offset by credentialing and sophistication in (some) destination country facilities, lack of benefits to poorer citizens in developing countries offering medical tourism remains a generic equity issue. Data collection, measures, and studies of medical tourism all need to be greatly improved if countries are to assess better both the magnitude and potential health implications of this trade.

    Thanks to the discovery of novel technologies and sophisticated analysis tools we can now 'see' molecules, genes and even patterns of gene expression, which have resulted in major advances in many areas of biology. Recently, similar technologies have been developed for behavioral studies. However, the wide implementation of such technological progress in behavioral research remains behind, as if there are inhibiting factors for accepting and adopting available innovations. The methods of the majority of studies measuring and interpreting behavior of laboratory animals seem to have frozen in time somewhere in the last century. As an example of the so-called classical tests, we will present the history and shortcomings of one of the most frequently used tests, the open field. Similar objections and critical remarks, however, can be made with regard to the elevated plus maze, light-dark box, various other mazes, object recognition tests, etc. Possible solutions and recommendations on how progress in behavioral neuroscience can be achieved and accelerated will be discussed in the second part of this review.

    2016-01-01

    A hundred years after its birth, general relativity has become a highly successful theory in the sese that it has passed many experimental and observational tests and finds widespread application to diverse set of cosmic phenomena. It remains an accurate research field as more tests are deployed, epitomized by the exciting prospect of detecting gravitational radiation directly. General realtivity is the essential foundation of modern cosmology and underlies our detailed description of the black holes and neutron stars that are ultimately responsible for the most powerful and dramatic cosmic sources. The interface with physics on both the largest and the smallest scales continues to be very fertile. In this talk I will attempt to highlight some key steps along the way to general relativity today.

    Full Text Available Historically, food fortification has served as a tool to address population-wide nutrient deficiencies such as rickets by vitamin D fortified milk. This article discusses the different policy strategies to be used today. Mandatory or voluntary fortification and fortified foods, which the consumer needs, also have to comply with nutritional, regulatory, food safety and technical issues. The ‘worldwide map of vitamin fortification’ is analysed, including differences between develop and developing countries. The vitamins, folate and vitamin D, are taken as practical examples in the review of the beneficial effect of different strategies on public health. The importance of the risk–benefit aspect, as well as how to identify the risk groups, and the food vehicles for fortification is discussed.

  12. On the effectiveness of smart technologies in the seismic protection of existing buildings Part II: Reinforced concrete structures

    Science.gov (United States)

    Mandara, A.; Ramundo, F.; Spina, G.

    2008-07-01

    The second part of a study concerning innovative intervention techniques for seismic protection of existing buildings is presented in this paper. The case of an existing framed r.c. structure, not designed for horizontal forces and extremely vulnerable to seismic action, is analyzed both in terms of maximum response reduction and energy dissipation. The proposed intervention approach, based on steel braces linked to the existing structure by passive or smart devices comes out appropriate and effective in the case of this type of buildings. The adopted control strategy produces a significant reducing effect on the elastic strain energy transmitted by the external perturbation to the structure, which is itself a fundamental safeguard aspect. The results prove the significantly improved capability of the system to dissipate input energy without structural damage, regardless of the specific seismic input.

    2002-09-01

    The objective of this report is to compile a survey of available technologies for separation of particles and to present research and development in the area of particle separation for biofuel plants smaller than 10 MW. Technical and economical opportunities to transfer the technologies used today in larger plants to smaller ones are discussed. As the health effects of aerosols are under investigation, the issue of separation of particle less than 1 {mu}m is especially scrutinised. Current research concerning the particle size distribution at different load is presented. The project has been realised partly as a literature survey, partly through contacts with scientists in the area and manufacturers of devices for flue gas cleaning and particle separation. The target group is owners of plants, manufacturers of devices and authorities with responsibility for air quality and energy planning. Fabric filters is an established technology that can perform low particle emissions (less than a few mg/m{sup 3}) at a low cost also at smaller plants. Also electrostatic precipitators can perform the same low emissions, but the cost for installation at smaller plants has to be reduced. Both these technologies can, properly designed, separate submicron particles. Cyclones can today as its best perform a little less than 100 mg/m{sup 3} at 13 % CO{sub 2}. Cyclones are used together with other technologies to achieve high separation at a low cost. Cyclones are attractive because of their simplicity and low price, but because they use inertia forces as separation mechanism, they can never separate submicron particles. Conventional scrubbers and flue gas condensers are capable of separation of submicron particles but the efficiency is lower compared with fabric filters and electrostatic precipitators. The emission level after a scrubber/flue gas condenser is about 70 - 80 mg/m{sup 3} at 13 % CO{sub 2}. New technologies for separation of particles oriented towards smaller plants and

    Möse, Josef R

    2007-09-13

    I began my career in 1945 by tracing the footsteps of the legendary Max von Pettenkofer and Robert Koch. At that time their influence was still discernible, and continues to be.The first major innovation was the introduction of antibiotics, which some people believed would now dispense with the need for disinfection and sterilization. The next major development was the introduction of hospital hygiene as a discipline in its own right, aimed at highlighting the growing risk of nosocomial infections, albeit also against the background of the, admittedly, brilliant but unceasingly innovative armamentarium of medical paraphernalia and fittings. As regards the pathogens, viruses were seen to play an increasingly more prominent role as nosocomial pathogens, giving rise to completely novel challenges and problems in the field of disinfection and sterilization. In 1956 at Prof. Pette's institute in Hamburg it generally took weeks to produce the results to diagnose poliomyelitis. Their value was immensely important for science - but their value to the doctor and patients was questionable. The introduction of inexpensive sterile disposable syringes and other disposable equipment represented, in my opinion, the next milestone. In the meantime, there was a dramatic increase in the overall constellation of problems caused by the continuing upsurge in antibiotic bacterial resistance. And with growing awareness of environmental issues, the late 60s set in motion a new avalanche where one had to strive not only to keep abreast of matters, but also to ensure that science continued to prevail as the highest instance. Today we are facing completely different, but in principle still similar problems in consolidating the status of disinfection and sterilization, e.g. when it comes to the ultra delicate devices that in some cases are heavily contaminated after routine clinical use. Hence we elderly infection control experts still have a task to accomplish: to issue warnings again and

    Akiki, Geoffrey M.

    1995-07-01

    Successive generations of semiconductors have necessitated increasingly more complex technologies to produce the desired densities, speeds and other functions. The requirements placed on the photomasks used to produce large-scale integrated circuits have concurrently increased. These changing requirements have dictated photomask technology shifts from optical steppers to electron-beam and laser pattern generators, more tightly controlled processes, as well as the investigation of techniques such as phase-shifting. The outlook for the future indicates that requirements will continue to grow more complex. This presentation describes projected roadmaps for photomask specifications and some suggested strategies to meet these enhanced requirements. Potential problem areas are highlighted, as well as related issues pertaining to the mask equipment and materials industry. A brief overview is also given on the current challenges associated with photomasks with particular emphasis on half-micron DUV lithography, and the 0.35-, 0.25- and 0.18-micron challenges. Techniques such as optical proximity correction and phase-shifting are also discussed in terms of their applicability and insertion into manufacturing. The current status of X- ray masks, as well as projections for the technical requirements and capabilities associated with their manufacture, is included. An outline of the Microlithographic Mask Development (MMD) contract objectives is also presented.

    In last 50 years, the field of scientific computing has seen a rapid change of vendors, architectures, technologies and the usage of systems. Despite all these changes the evolution of performance on a large scale however seems to be a very steady and continuous process. Moore's Law is often cited in this context. If the authors plot the peak performance of various computers of the last 5 decades in Figure 1 that could have been called the supercomputers of their time they indeed see how well this law holds for almost the complete lifespan of modern computing. On average they see an increase in performance of two magnitudes of order every decade.

  1. Today's View on Strangeness

    CERN Document Server

    Ellis, Jonathan Richard

    2005-01-01

    There are several different experimental indications, such as the pion-nucleon sigma term and polarized deep-inelastic scattering, which suggest that the nucleon wave function contains a hidden s bar s component. This is expected in chiral soliton models, which also predicted the existence of new exotic baryons that may recently have been observed. Another hint of hidden strangeness in the nucleon is provided by copious phi production in various N bar N annihilation channels, which may be due to evasions of the Okubo-Zweig-Iizuka rule. One way to probe the possible polarization of hidden s bar s pairs in the nucleon may be via Lambda polarization in deep-inelastic scattering.

Landmarks of contemporary art of a restless world are in constant motion and transformation. The border between the visual arts and information, especially for the new generations, is in a continuous confrontation. But here, the field of the arts once in elite, being conditioned by the access to education and culture offered by a particular social standard and by the welfare condition, tends to expand and become more accessible to all social groups. The images tend to become a subject of debate. Along with the new millennium, increasing masses of people discover the cultural tourism, take note of the existence of the art and overwhelmed with their presence the great museums of the world.

  3. Comparative Study of CAD Software, Web3D Technologies and Existing Solutions to Support Distance-Learning Students of Engineering Profile

    Full Text Available Interactive simulations, virtual environments and 3D interfaces significantly contribute to the process of learning through collab-oration and interaction with distant participants, and through simulation of real environments and real life situations. Depend-ing on the needs and case studies, different technologies, soft-ware packages and their combinations are used. In this paper, we present a comparative study based on the use of different CAD software in conjunction with Web3D technologies for teaching students at the Department of Engineering Management. With respect to the specificity of the profile of students undergoing training, the selection of CAD packages is reduced to the five most commonly used in this field: SolidWorks, Inventor, CATIA, Pro/ENGINEER and AutoCAD. During research, we found that Inventor and AutoCAD do not export VRML/X3D file types; hence, this paper provides only the basic functions of Inventor without integration of Web3D technologies. Combining with AutoCAD is described due to the existence of a number of plug-ins, as well as exporters and working groups working on Auto-CAD-X3D development. The main criteria for evaluating and ranking CAD packages used here are learning curve, export and import from CAD to X3D and vice versa, file types and sizes, types of nodes and material properties. We also review the tech-nology used to display 3D content on the Internet, and the rea-sons why we decided to use Web3D technologies in combination with these CAD packages. This paper presents specific conclu-sions, the advantages and disadvantages of software and technol-ogy, as well as predictions regarding further development of existing platforms and environments.

    Many relatively small electrostatic precipitators (ESP`s) exist which collect fly ash at remarkably high efficiencies and have been tested consistently at correspondingly high migration velocities. But the majority of the world`s coal supplies produce ashes which are collected at much lower migration velocities for a given efficiency and therefore require correspondingly large specific collection areas to achieve acceptable results. Early trials of flue gas conditioning (FGC) showed benefits in maximizing ESP performance and minimizing expense which justified continued experimentation. Trials of several dozen ways of doing it wrong eventually developed a set of reliable rules for doing it right. One result is that the use of sulfur trioxide (SO{sub 3}) for adjustment of the resistivity of fly ash from low sulfur coal has been widely applied and has become an automatically accepted part of the option of burning low sulfur coal for compliance with the Clean Air Act of l990 in the U.S.A. Currently, over 100,000 MW of generating capacity is using FGC, and it is estimated that approximately 45,800 MW will utilize coal-switching with FGC for Clean Air Act emission compliance. Guarantees that this equipment will be available to operate at least 98 percent of the time it is called upon are routinely fulfilled.

    The most important contributions of Einstein involve 5 fields of physics : the existence of quanta (light quanta, stimulated radiation emission and Bose-Einstein condensation), relativity, fluctuations (Brownian motion and thermodynamical fluctuations), the basis of quantum physics and cosmology (cosmological constant and the expansion of the universe). Diverse and renowned physicists have appreciated the development of modern physics from Einstein's ideas to the knowledge of today. This book is a collective book that gathers their work under 7 chapters: 1) 1905, a new beginning; 2) from the Einstein, Podolsky and Rosen's article to quantum information (cryptography and quantum computers); 3) the Bose-Einstein condensation in gases; 4) from stimulated emission to the today's lasers; 5) Brownian motion and the fluctuation-dissipation theory; 6) general relativity; and 7) cosmology.

    This report to Congress was prepared on behalf of the Secretary of the US Department of Energy (DOE) in response to Sections 127 and 128 of the Energy Policy Act of 1992 (EPAct), Pub. L. 102-486. In preparing the report to the Congress, DOE has assessed the national and regional energy savings potential of products already on the market and those that will be available to consumers by the late 1990s. The Department has also examined the present cost-effectiveness of these emerging appliances as mature technologies. To help in its assessment, DOE organized eight workshops at which representatives from manufacturing and building industries, utilities, retailers and wholesalers, public interest groups and Federal and state government agencies could express their views. The information derived from these workshops was key to the formulation of the report`s general and specific recommendations. DOE has concluded that the Federal Government can effectively stimulate the market for emerging technologies by forming partnerships with the appliance industry and other interested parties promoting the use of highly efficient appliances. Based on the interaction with industry at the eight workshops and through direct contact, DOE has concluded that Federal action and technical assistance is not only desired by industry, but crucial to the expansion of these markets. Section 128 of EPAct requires an assessment of the energy savings and environmental benefits of replacing older, less efficient appliances with more efficient products than currently required by Federal law. Since early replacement of appliances is but one possible market-stimulating action, DOE has elected to include its discussion as part of the overall report to the Congress.

  17. Information surety for today and tomorrow

    Fletcher, S.K.

    1993-07-01

    Information Surety is the enhancement of the confidentiality, integrity, and availability of information and software systems. It is attained through sequential steps: identification of software reliability requirements and information protection needs, designing for a balanced level of risk throughout the system, and application of appropriate software and hardware technologies and procedures. The ability to apply these steps when developing systems is impaired by a general lack of understanding of surety issues by system developers, and by the fact that there are many separate areas of knowledge involved that are not currently integrated into a disciplined approach (e.g., risk assessment, information access control in computers and networks, secure messaging, trusted software development). Our best systems today are achieved by clever designers who use ad-hoc methods. In the absence of good development tools, technologies may be applied haphazardly and/or retrofitted, without yielding balanced protection. This paper will take the audience through an exploration of the elements of information surety, some common misconceptions about information surety today, and the even greater challenges on the horizon. It will end with some suggestions for research areas which will help evolve the discipline of information surety.

    Inside the industrial applications of the sealed radioactive sources, there are clearly exist two defined branches for which these materials are used: radioactive sources used in fixed equipment and in mobile ones. These devices are used in a countless of applications and every time with more advanced technological systems. This requires a permanent improvement inside the training of the responsible one and in turn it introduces an obligatory change to other intervention groups during the useful life of the device. The accident risks to those that are associate the use of these equipment, they are errors during the operation, undue use, maintenance carried out by personal without knowledge, flaws of human type or negligence and incidents happened during the transport. All these 'risks' its are surrounded of different groups of factors that influence during the safe use of the radioactive material, inside the installation of one way or another. Then it stands out the importance of implanting aspects of 'Safety Culture', evaluations of aptitude of the responsible one for the radiological safety, introduction of improvements in aspects of quality and communication of risks, chord to what indicates the normative of the Argentine Republic and the international requirements, which will be approached in the present work.

    Full Text Available This essay discusses the situation of philosophy today in an era of mixed modern, postmodern, and traditional values and social patterns. It argues, with reference to postmodern architecture and to the German philosophers Hegel and Heidegger, that we should reject polarizing conceptual dualities, and that we need to seek out new kinds of less centered and less hierarchical unities that take advantage of the internal tensions and spacings within intellectual and cultural formations. It concludes with a discussion of the promises and problems of dialogue between Eastern and Western philosophies in today’s world.

    Rogers, D E; Blendon, R J

    1984-05-01

    Some recent circumstances, including the nation's economic difficulties, a probable physician surplus, a declining need for acute-care medical beds, and an overwhelming public perception that medical care is too expensive, are creating serious problems for academic medical centers today. To survive, many academic medical centers probably will make certain short-term adaptations that will be viewed as undesirable by many. We suggest four initiatives that may help academic centers maintain their vital national role. These initiatives include becoming major public advocates for the medical care needs of the least fortunate; a sharp reduction in the training of subspecialists; the commitment of more of their faculty practice income to academic research, teaching, and support of low-income students; and refocusing attention on the training of young persons to be the physicians of tomorrow.

    If alien civilizations do, or did, exist, their technology will impact their environment. Some consideration has been given to the detection of large-scale astro-engineering, such as Dyson spheres. However, a very advanced technology might leave more subtle footprints requiring sophisticated scientific methods to uncover. We must not overlook the possibility that alien technology has impacted our immediate astronomical environment, even Earth itself, but probably a very long time ago. This raises the question of what traces, if anything, might remain today. I shall consider the possibilities of biological, geological and physical traces, and suggest ways that we might search for them.

    Based on Jiaozhou bay subsea tunnel in Qingdao city, the blasting control technology that Jiaozhou bay subsea tunnel crosses existing buildings is studied by combining the experimental equation of charge establishment with coherent code. According to a large number of tunnel construction field test data, the laws of vibration wave propagation and the calculation parameters of charge are obtained, and then the maximum allowable amount of primary explosive segment is calculated. Based on the above methods, the. Blasting program is optimized and house maximum blasting velocity is controlled under 2 cm/s. The test results of building blasting vibration velocity in different floors show the velocity of the first floor is greater than the velocity on each floor. So the velocity of the first floor is recommended to be a control velocity while the maximum charge is calculated. This study is not only useful to ensure building's stabilization when blasting in Jiaozbou bay subsea tunnel but also offers theoretical and methodological experiences to the similar engineering.%以青岛胶州湾海底隧道陆域段工程为背景,结合萨氏装药量计算经验公式及相关规范,对胶州湾海底隧道下穿群楼时的爆破控制技术进行研究,基于隧道施工爆破的大量现场测试数据,回归分析得出了依托工程的振动波传播规律和装药量计算参数,由此计算出允许最大段起爆药量,进而优化大断面隧道爆破方案,实现了房屋最大振速控制在2 cm/s以下根据建筑物不同楼层的爆破振速的测试结果,底层振速大于各楼层振速是普遍规律,因此在计算最大段起爆药量时,应以建筑物底层的爆破振速作为控制基准.研究成果保证了胶州湾海底隧道下穿群楼爆破时建筑物的稳定,并对类似工程有借鉴意义.

Así, varios cambios visibles, tangibles o en construcción cuestionan la formación de los usos y su estudio en referencia a la sociología de los usos. En un primer tiempo mostraremos, precisamente, que la oferta ha cambiado de manera profunda al pasar las NTIC de los años 1980 a las TIC numéricas y que, en segundo lugar, esta mutación se opone a la definición de los usos sociales y sus condiciones de formación en referencia a las NTIC. En efecto, pueden despejarse ya cuatro características de las TICN : la polivalencia, la apertura, la formación de un dispositivo y la pérdida de la función dominante. El trabajo de investigación sobre las mutaciones de la formación de los usos mismos está aquí esbozada solamente desde un punto de vista teórico a fin de demostrar todo el interés que habría por estudiar estas mutaciones; porque también se trata de interrogarse sobre la evolución de las problemáticas de las Ciencias de la Comunicación en este principio del siglo XXI. The aim of this article is to think about social uses development from a double perspective: nowadays information and communication features; and the supply system they belong to.

First of all, we’ll expose how that technology supply has suffered a deep change going through an evolution from 1980’s NTIC to numerical TIC. Second, this mutation is opposed to social uses definition and their development conditions, according to NTIC.

    Full Text Available Since the beginning of the Reform Era in 1979, there has been a rapid growth and development of religious belief and practice in China. A substantial new scholarly literature has been generated in the attempt to document and understand this. This essay identifies the most important contributions to that literature and discusses areas of agreement and controversy across the literature. Along with new data, new paradigms have developed to frame research on Chinese religions. The paradigm derived from C. K. Yang’s classic work in the 1960s came from structural functionalism, which served to unite research in the humanities and social sciences. However, structural functionalism has been abandoned by the new generation of scholars. In the humanities, the most popular paradigm derives from Michel Foucault, but there are also scholars who use neo-Durkheimian and neo-Weberian paradigms. In the social sciences, the dominant paradigms tend to focus on state-society relations. None of these paradigms fully captures the complexity of the transformations happening in China. We recommend greater dialogue between the humanities and social sciences in search of more adequate theoretical frameworks for understanding Chinese religions today.

  17. Artificial insemination in pigs today.

    Knox, R V

    2016-01-01

    Use of artificial insemination (AI) for breeding pigs has been instrumental for facilitating global improvements in fertility, genetics, labor, and herd health. The establishment of AI centers for management of boars and production of semen has allowed for selection of boars for fertility and sperm production using in vitro and in vivo measures. Today, boars can be managed for production of 20 to 40 traditional AI doses containing 2.5 to 3.0 billion motile sperm in 75 to 100 mL of extender or 40 to 60 doses with 1.5 to 2.0 billion sperm in similar or reduced volumes for use in cervical or intrauterine AI. Regardless of the sperm dose, in liquid form, extenders are designed to sustain sperm fertility for 3 to 7 days. On farm, AI is the predominant form for commercial sow breeding and relies on manual detection of estrus with sows receiving two cervical or two intrauterine inseminations of the traditional or low sperm doses on each day detected in standing estrus. New approaches for increasing rates of genetic improvement through use of AI are aimed at methods to continue to lower the number of sperm in an AI dose and reducing the number of inseminations through use of a single, fixed-time AI after ovulation induction. Both approaches allow greater selection pressure for economically important swine traits in the sires and help extend the genetic advantages through AI on to more production farms.

Esta cuestión de Hitler en la actualidad posee diversos problemas históricos que están íntimamente conectados con otros morales. En este trabajo, sin embargo, pretendo concentrarme primordialmente en su dimensión histórica. A la luz del sorprendente ascenso de Hitler en la moderna conciencia histórica, esto puede llevarnos a la siguiente pregunta: ¿No hemos otorgado al dictador nazi un poder aún mayor que cuando estaba vivo y comandando sus divisiones de la Wehrmacht en el punto culminante de sus conquistas?___________________ABSTRACT:By the end of the twentieth century, it can be said, Hitler was more alive and prominent than at the height of his power a half-century before. How did Hitler become this way? Isn’t he dead? How can he become so prominent more than half a century after his death? The issue of Hitler today poses several historical problems that are deeply moral problems as well. In this work, however, I intend to concentrate primarily on their historical dimension. In light of Hitler’s astonishing rise in modern historical consciousness, this leads to the inevitable question: Have we not granted to Hitler a far greater power over us than ever he had when he was alive and commanding his Wehrmacht divisions at the farthest extent of his conquests?

    Disinvestment is critical for ensuring the long-term sustainability of health-care services. Key barriers to disinvestment are heterogeneity between research and clinical settings, absence of evidence of effectiveness of some health technologies, and exposure of patients and organizations to risks and poor outcomes. We aimed to develop a feasible research design that can evaluate disinvestment in health technologies of uncertain effectiveness or cost-effectiveness. This article (1) establishes the need for disinvestment methodologies, (2) identifies the ethical concerns and feasibility constraints of conventional research designs for this issue, (3) describes the planning, implementation, and analytical framework for a novel disinvestment-specific study design, and (4) describes potential limitations in application of this design. The stepped-wedge, roll-in cluster randomized controlled trial can facilitate the disinvestment process, whereas generating evidence to determine whether the decision to disinvest was sound in the clinical environment. A noninferiority research paradigm may be applied to this methodology to demonstrate that the removal of a health technology does not adversely affect outcomes. This research design can be applied across multiple fields and will assist determination of whether specific health technologies are clinically effective, cost-effective, and safe.

  11. Botulinum toxin: yesterday, today, tomorrow

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Botulinum toxin (BoNT is a bacterial neurotoxin presented with seven serotypes that inhibit neurotransmitter release from nerve endings. The serotypes of BoNT are antigenically dissimilar, act via different, but interconnected mechanisms, and are not interchangeable. The activity of BoNT is associated with impaired neuroexocytosis occurring in several steps: from the binding of BoNT to its specific receptor on the axon terminal membrane to the proteolytic enzymatic cleavage of SNARE substrate. The effect of BoNT is considered to be restricted to the peripheral nervous system, but when given in particularly high doses, it has been recently shown to affect individual brain structures. In addition, by modulating peripheral afferentation, BoNT may influence the excitability of central neuronal structures at both spinal and cortical levels. Only BoNT serotypes A and B are used in clinical practice and aesthetic medicine. The type A has gained the widest acceptance as a therapeutic agent for more than 100 abnormalities manifesting themselves as muscular hyperactivity, hyperfunction of endocrine gland, and chronic pain. The effect of BoNT preparations shows itself 2-5 days after injection, lasts 3 months or more, and gradually decreases with as a result of pharmacokinetic and intracellular reparative processes. Biotechnology advances and potentialities allow purposefully modification of the protein molecular structure of BoNT, which expands the use and efficiency of performed therapy with neurotoxins. Recombinant technologies provide a combination of major therapeutic properties of each used BoNT serotype and expand indications for recombinant chimeric toxins.

    2007-01-01

    The current status and research trends of detection techniques for DNA-based analysis such as DNA finger printing, sequencing, biochips and allied fields are examined. An overview of main detectors is presented vis-à-vis these DNA operations. The biochip method is explained, the role of micro- and nanoelectronic technologies in biochip realization is highlighted, various optical and electrical detection principles employed in biochips are indicated, and the operational mechanisms of these detection devices are described. Although a diversity of biochips for diagnostic and therapeutic applications has been demonstrated in research laboratories worldwide, only some of these chips have entered the clinical market, and more chips are awaiting commercialization. The necessity of tagging is eliminated in refractive-index change based devices, but the basic flaw of indirect nature of most detection methodologies can only be overcome by generic and/or reagentless DNA sensors such as the conductance-based approach and the DNA-single electron transistor (DNA-SET) structure. Devices of the electrical detection-based category are expected to pave the pathway for the next-generation DNA chips. The review provides a comprehensive coverage of the detection technologies for DNA finger printing, sequencing and related techniques, encompassing a variety of methods from the primitive art to the state-of-the-art scenario as well as promising methods for the future.

    ?Ducts in conditioned space (DCS) represent a high priority measure for moving the next generation of new homes to the Zero Net Energy performance level. Various strategies exist for incorporating ducts within the conditioned thermal envelope. To support this activity, in 2013 the Pacific Gas & Electric Company initiated a project with Davis Energy Group (lead for the Building America team, Alliance for Residential Building Innovation) to solicit builder involvement in California to participate in field demonstrations of various DCS strategies. Builders were given incentives and design support in exchange for providing site access for construction observation, diagnostic testing, and builder survey feedback. Information from the project was designed to feed into California's 2016 Title 24 process, but also to serve as an initial mechanism to engage builders in more high performance construction strategies. This Building America project complemented information collected in the California project with BEopt simulations of DCS performance in hot/dry climate regions.

    The study outlines the considerable dynamics of technological development. Among others, the need for accelerating the market penetration of innovative measures is discussed. There are great discrepancies in the practical implementation of different measures, and it is shown that so-called low-investive measures can make a significant contribution to energy conservation. Implementation of complex measures also shows that the results achieved are strongly dependent on the energy savings goals on the one hand and on the regional or local housing situation and the resulting price levels on the other hand. This stresses the influence of the design of boundary conditions, and the question that comes up is the function of funding policy. The housing industry will have to intensify its energetic portfolio management during the next few years to cope with the new challenges, and the consumer behaviour has great influence. Here, too, efficient behaviour has considerable energy saving potential. The next few years will show if and inhowfar measures for higher transparency will have an effect. (orig.)

    Air sealing of building enclosures is a difficult and time-consuming process. Current methods in new construction require laborers to physically locate small and sometimes large holes in multiple assemblies and then manually seal each of them. The innovation demonstrated under this research study was the automated air sealing and compartmentalization of buildings through the use of an aerosolized sealant, developed by the Western Cooling Efficiency Center at University of California Davis.
    CARB sought to demonstrate this new technology application in a multifamily building in Queens, NY. The effectiveness of the sealing process was evaluated by three methods: air leakage testing of overall apartment before and after sealing, point-source testing of individual leaks, and pressure measurements in the walls of the target apartment during sealing. Aerosolized sealing was successful by several measures in this study. Many individual leaks that are labor-intensive to address separately were well sealed by the aerosol particles. In addition, many diffuse leaks that are difficult to identify and treat were also sealed. The aerosol-based sealing process resulted in an average reduction of 71% in air leakage across three apartments and an average apartment airtightness of 0.08 CFM50/SF of enclosure area.

    Storlazzi, Curt D.; Dartnell, Peter; Hatcher, Gerald A.; Gibbs, Ann E.

    2016-09-01

    The rugosity or complexity of the seafloor has been shown to be an important ecological parameter for fish, algae, and corals. Historically, rugosity has been measured either using simple and subjective manual methods such as `chain-and-tape' or complicated and expensive geophysical methods. Here, we demonstrate the application of structure-from-motion (SfM) photogrammetry to generate high-resolution, three-dimensional bathymetric models of a fringing reef from existing underwater video collected to characterize the seafloor. SfM techniques are capable of achieving spatial resolution that can be orders of magnitude greater than large-scale lidar and sonar mapping of coral reef ecosystems. The resulting data provide finer-scale measurements of bathymetry and rugosity that are more applicable to ecological studies of coral reefs than provided by the more expensive and time-consuming geophysical methods. Utilizing SfM techniques for characterizing the benthic habitat proved to be more effective and quantitatively powerful than conventional methods and thus might portend the end of the `chain-and-tape' method for measuring benthic complexity.

    Williamson, E Diane

    2016-07-03

    The purpose of this review is to survey current, emerging and predicted future biotechnologies which are impacting, or are likely to impact in the future on the life sciences, with a projection for the coming 20 years. This review is intended to discuss current and future technical strategies, and to explore areas of potential growth during the foreseeable future. Information technology approaches have been employed to gather and collate data. Twelve broad categories of biotechnology have been identified which are currently impacting the life sciences and will continue to do so. In some cases, technology areas are being pushed forward by the requirement to deal with contemporary questions such as the need to address the emergence of anti-microbial resistance. In other cases, the biotechnology application is made feasible by advances in allied fields in biophysics (e.g. biosensing) and biochemistry (e.g. bio-imaging). In all cases, the biotechnologies are underpinned by the rapidly advancing fields of information systems, electronic communications and the World Wide Web together with developments in computing power and the capacity to handle extensive biological data. A rationale and narrative is given for the identification of each technology as a growth area. These technologies have been categorized by major applications, and are discussed further. This review highlights: Biotechnology has far-reaching applications which impinge on every aspect of human existence. The applications of biotechnology are currently wide ranging and will become even more diverse in the future. Access to supercomputing facilities and the ability to manipulate large, complex biological datasets, will significantly enhance knowledge and biotechnological development.

    Science.gov (United States)

    Figueroa, Gustavo

    2011-10-01

    Bioethics was born not only as an aftermath of medical technological advance but also from underlying philosophical conceptions about man, that determine scientific research. Analyzing occidental ethics, Heidegger showed that animalism was the only human dimension considered and thereby the domain of measurable objectiveness. He postulated that the essence of human existence as being-in-the-world is ethical and revealed through an original consciousness. Unlike moral conscience, original conscience calls to authenticity, to hear his constitutive nihilism as a "Being-referred-to-death". The founding ground of bioethics may be to listen to this primary being-guilty prior to the derived guilts, e.g. faults, deficiencies and shortcomings of specific daily actions.

  5. Epidemiology today: Mitigating threats to an ecosystem.

    Science.gov (United States)

    Kreiger, Nancy

    2016-06-27

    Ecosystems comprise all the living and non-living things in a particular area (e.g., rain forest, desert), which interact and maintain equilibrium. Loss of equilibrium (e.g., clear-cutting trees in a rain forest) can mean the decline of the ecosystem, unless it is able to adapt to the new circumstances. The term "knowledge ecosystem" describes an approach to managing knowledge in a particular field; the components of this system include the people, the technological skills and resources, and information or data. Epidemiology can be thought of as a knowledge ecosystem and, like ecological systems, its existence can be threatened, from both internal and external forces that may alter its equilibrium. This paper describes some threats to the epidemiology knowledge ecosystem, how these threats came about, and what responses we can make that may serve to mitigate those threats.

    Passion in today's health care leaders is essential as health care organizations face increasing demands for survival. Leaders in health care have been educated, selected, promoted, and retained based on their analytical and creativity skills. Today's health care leaders must also have emotional intelligence. Emotional intelligence is primal for passion. Emotional intelligence, which leads to passion, is crucial to the survivability of today's health care organizations. In order for health care organizations to go from good to great, the leader must inspire followers through passion. This article encourages health care leaders to gain awareness of emotional intelligence and to use emotional intelligence as part of their leadership to inspire passion. Through passion, leaders and followers become more motivated to accomplish the health care mission of serving others.

    2015-01-01

    Full Text Available Advancements in input device and sensor technologies led to the evolution of the traditional human-machine interaction paradigm based on the mouse and keyboard. Touch-, gesture- and voice-based interfaces are integrated today in a variety of applications running on consumer devices (e.g., gaming consoles and smartphones. However, to allow existing applications running on desktop computers to utilize natural interaction, significant re-design and re-coding efforts may be required. In this paper, a framework designed to transparently add multi-modal interaction capabilities to applications to which users are accustomed is presented. Experimental observations confirmed the effectiveness of the proposed framework and led to a classification of those applications that could benefit more from the availability of natural interaction modalities.

    The U.S. Flywheel Systems' flywheel energy storage system could be the answer to a critical question: How do we replace conventional chemical batteries with a more-efficient system that lasts longer and is non-polluting? The new product, which has a virtually unlimited life expectancy, has a storage capacity four times greater per pound than conventional chemical batteries. USFS designed and built each component of the system—from the specially wound carbon fiber wheel, the magnetic bearing, the motor/generator, and the electronic control. The flywheel is designed to spin at speeds up to 100,000 rpm and deliver about 50 horsepower using a proprietary high-speed, high-power-density motor/generator that is the size of a typical coffee mug. Some of the important markets and applications for the flywheel storage system include electric vehicles, back-up power supply, peak power smoothing, satellite energy storage systems, and locomotive power.

    1994-12-01

    Described herein are the results of the FY1994 research program for solar/energy-conversion technologies retrofitted to existing buildings. The estimated effects and economic viability of retrofitting technologies show that they bring very high energy-saving effects when applied to heating and hot water supply, which consume a large portion of energy, but relatively low energy-saving effects when applied to cooling, solar walls, glazed balconies and transparent insulators. The study on applicability of these technologies in Japan indicates that the technologies which can recover cost within an average life time are those applied to windows, solar collector systems for hot water supply and heating, and transparent insulators. Although these technologies are low in applicability to cooling viewed from the angle of cost recovery, retrofitted radiation type cooling systems improve not only cooling and energy-saving effects but also comfortableness.

    Today, petroleum products account for 97% of the energy consumed in road transport. The purpose of replacing these products with alternative energies is to reduce oil dependence as well as greenhouse gas emissions. The high price of oil has promoted the use of 'conventional' alternative motor fuels (biofuels, LPG, NGV) and also renewed interest in syn-fuels (GTL, CTL, BTL) that have already given rise to industrial and pilot projects.

    Aromatics are the essential building blocks for some of the largest petrochemical products in today's use. To the vast majority they are consumed to produce intermediates for polymer products and, hence, contribute to our modern lifestyle. Their growth rates are expected to be in line with GDP growth in future. This contrasts the significantly lower growth rates of the primary sources for aromatics - fuel processing and steam cracking of naphtha fractions. A supply gap can be expected to open up in future for which creative solutions will be required. (orig.)

    No statistician, social scientist or tarot card reader is needed to attest that the gap between the rich and poor in America is increasing. Further, most Americans don't care that much about it. There are also more rich people today living in the U.S. and there are more people living in poverty. Between 2000 and 2002, the number of Americans living in poverty increased by nearly 3 million to 34.6 million. Of these, 12% (or about one half a million persons) are living extreme poverty and many are children, with 16.7% likely to be poor (National Association of Social Workers, 2003).

    2016-01-01

    Full Text Available Consumer behavior study is a new, interdisciplinary and emerging science, developed in the 1960s. Its main sources of information come from economics, psychology, sociology, anthropology and artificial intelligence. If a century ago, most people were living in small towns, with limited possibilities to leave their community, and few ways to satisfy their needs, now, due to the accelerated evolution of technology and the radical change of life style, consumers begin to have increasingly diverse needs. At the same time the instruments used to study their behavior have evolved, and today databases are included in consumer behavior research. Throughout time many models were developed, first in order to analyze, and later in order to predict the consumer behavior. As a result, the concept of Big Data developed, and by applying it now, companies are trying to understand and predict the behavior of their consumers.

  8. The Second Law Today: Using Maximum-Minimum Entropy Generation

    2015-11-01

    Full Text Available There are a great number of thermodynamic schools, independent of each other, and without a powerful general approach, but with a split on non-equilibrium thermodynamics. In 1912, in relation to the stationary non-equilibrium states, Ehrenfest introduced the fundamental question on the existence of a functional that achieves its extreme value for stable states, as entropy does for the stationary states in equilibrium thermodynamics. Today, the new branch frontiers of science and engineering, from power engineering to environmental sciences, from chaos to complex systems, from life sciences to nanosciences, etc. require a unified approach in order to optimize results and obtain a powerful approach to non-equilibrium thermodynamics and open systems. In this paper, a generalization of the Gouy–Stodola approach is suggested as a possible answer to the Ehrenfest question.

    1995-12-31

    Subsurface barrier walls have been an important component of site remediation efforts for nearly thirty years. However, until the last decade, limited design options were available for barrier wall construction. Most barrier walls were constructed using traditional technologies such as soil-bentonite slurry trench and, in some instances, conventional compacted clay. While other technologies certainly existed, such as vibrating beam and sheet pile walls, they represented a minor share of the remediation market. Today the remediation engineer considering a subsurface barrier wall-based remediation is confronted with a baffling array, of new technologies and permutations of these technologies. Moreover, new technologies are entering the marketplace seemingly on a monthly basis. A partial listing of available barrier wall technologies is presented.

    During the last three decades the general public's initial opinions about ETI and SETI changed, turning ignorance, fear and superficiality into a gradual understanding of the importance of these concepts. After a brief analysis of this changing psycho-sociological attitude, the paper provides an "estimate of the situation" about general interest for ETI and SETI, suggesting a growing awareness in today's public opinion. Science fiction movies like Close Encounters of the Third Kind and E.T. the Extra-Terrestrial and popular interest in UFOs as visitors from outer space played a major role in the average man's acceptance of the reality of extra-terrestrial life and its meaning for mankind.

    2016-01-01

    Enteric neuropathy is a term indicating an impairment of the innervation supplying the gastrointestinal tract. The clinical phenotypes of the enteric neuropathies are the 'tip of the iceberg' of severe functional digestive diseases, such as intestinal pseudo-obstruction syndromes (e.g., chronic intestinal pseudo-obstruction). Despite progress acquired over the years, the pathogenetic mechanisms leading to enteric neuropathies are still far from being elucidated and the therapeutic approaches to these patients are mainly supportive, rather than curative.The purpose of this chapter is to review the advancements that have been done in the knowledge of enteric neuropathies identified in adult patients ('tomorrow'), going through where we currently are ('today') following a brief history of the major milestones on the pioneering discoveries in the field ('yesterday').

    2011-01-01

    We review here some of the major open issues and challenges in black hole physics today, and the current progress on the same. It is pointed out that to secure a concrete foundation for the basic theory as well as astrophysical applications for black hole physics, it is essential to gain a suitable insight into these questions. In particular, we discuss the recent results investigating the final fate of a massive star within the framework of the Einstein gravity, and the stability and genericity aspects of the gravitational collapse outcomes in terms of black holes and naked singularities. Recent developments such as spinning up a black hole by throwing matter into it, and physical effects near naked singularities are considered. It is pointed out that some of the new results obtained in recent years in the theory of gravitational collapse imply interesting possibilities and understanding for the theoretical advances in gravity as well as towards new astrophysical applications.

    2014-03-01

    Quantum computers, string theory, holographic universes - to the general audience, today's physics can be as mystifying as it is fascinating. But modern ideas evolved from an earlier phase of physics - Newtonian mechanics, simple cause and effect - that is in principle easier for the non-expert to grasp. I have found that writing about physics from a historical and biographical perspective is an effective way to convey modern thinking by explaining where it comes from - it is a way of carrying the reader from concepts that make intuitive sense to ideas that seem, on first encounter, utterly bizarre. Smuggling explanations into stories satisfies the reader's desire for narrative - bearing in mind that narrative can include the evolution of ideas as well as tales about intriguing and original people.

    2016-02-01

    Full Text Available Background: Global public health today faces new challenges and is impacted by a range of actors from within and outside state boundaries. The diversity of the actors involved has created challenges and a complex environment that requires a new context-tailored global approach. The World Federation of Public Health Associations has embarked on a collaborative consultation with the World Health Organization to encourage a debate on how to adapt public health to its future role in global health. Design: A qualitative study was undertaken. High-level stakeholders from leading universities, multilateral organizations, and other institutions worldwide participated in the study. Inductive content analyses were performed. Results: Stakeholders underscored that global public health today should tackle the political, commercial, economic, social, and environmental determinants of health and social inequalities. A multisectoral and holistic approach should be guaranteed, engaging public health in broad dialogues and a concerted decision-making process. The connection between neoliberal ideology and public health reforms should be taken into account. The WHO must show leadership and play a supervising and technical role. More and better data are required across many programmatic areas of public health. Resources should be allocated in a sustainable and accountable way. Public health professionals need new skills that should be provided by a collaborative global education system. A common framework context-tailored to influence governments has been evaluated as useful. Conclusions: The study highlighted some of the main public health challenges currently under debate in the global arena, providing interesting ideas. A more inclusive integrated vision of global health in its complexity, shared and advocated for by all stakeholders involved in decision-making processes, is crucial. This vision represents the first step in innovating public health at the

  5. The Relativity of Existence

    CERN Document Server

    Heinrich, Stuart

    2012-01-01

    Despite the success of physics in formulating mathematical theories that can predict the outcome of experiments, we have made remarkably little progress towards answering some of the most basic questions about our existence, such as: why does the universe exist? Why is the universe apparently fine-tuned to be able to support life? Why are the laws of physics so elegant? Why do we have three dimensions of space and one of time? How is it that the universe can be non-local and non-causal at the quantum scale, and why is there quantum randomness? In this paper, it is shown that all of these questions are answered if existence is relative, and moreover, it seems that we are logically bound to accept it.

  6. This elusive objective existence

    CERN Document Server

    Mohrhoff, U

    2004-01-01

    Zurek's existential interpretation of quantum mechanics suffers from three classical prejudices, including the belief that space and time are intrinsically and infinitely differentiated. They compel him to relativize the concept of objective existence in two ways. The elimination of these prejudices makes it possible to recognize the quantum formalism's ontological implications - the relative and contingent reality of spatiotemporal distinctions and the extrinsic and finite spatiotemporal differentiation of the physical world - which in turn makes it possible to arrive at an unqualified objective existence. Contrary to a widespread misconception, viewing the quantum formalism as being fundamentally a probability algorithm does not imply that quantum mechanics is concerned with states of knowledge rather than states of Nature. On the contrary, it makes possible a complete and strongly objective description of the physical world that requires no reference to observers. What objectively exists, in a sense that r...

    Evaluating biomedical technology poses a significant challenge in light of the complexity and rate of introduction in today's healthcare delivery system. Successful evaluation requires an integration of clinical medicine, science, finance, and market analysis. Little guidance, however, exists for those who must conduct comprehensive technology evaluations. The 3Q Method meets these present day needs. The 3Q Method is organized around 3 key questions dealing with 1) clinical and scientific basis, 2) financial fit and 3) strategic and expertise fit. Both healthcare providers (e.g., hospitals) an

  9. Relativity, Dimensionality, and Existence

    Petkov, Vesselin

    A 100 years have passed since the advent of special relativity and 2008 will mark another important to all relativists anniversary - 100 years since Minkowski gave his talk "Space and Time" on September 21, 1908 in which he proposed the unifi- cation of space and time into an inseparable entity - space-time. Although special relativity has been an enormously successful physical theory no progress has been made in clarifying the question of existence of the objects represented by two of its basic concepts - space-time and world lines (or worldtubes in the case of extended bodies). The major reason for this failure appears to be the physicists' tradition to call such questions of existence philosophical. This tradition, however, is not quite consistent. In Newtonian mechanics physicists believe that they describe real objects whenever they talk about particles - one of the basic concepts of Newtonian physics. The situation is the same in quantum physics - no one questions the existence of electrons, protons, etc. Then why should the question of existence of worldtubes (representing particles in relativity) be regarded as a philosophical question?

  12. Introduction: The Continued Importance of Smallholders Today

    2016-10-01

    Full Text Available Smallholders remain an important part of human-environment research, particularly in cultural and political ecology, peasant and development studies, and increasingly in land system and sustainability science. This introduction to the edited volume explores land use and livelihood issues among smallholders, in several disciplinary and subfield traditions. Specifically, we provide a short history of smallholder livelihood research in the human-environment tradition. We reflect on why, in an age of rapid globalization, smallholder land use and livelihoods still matter, both for land system science and as a reflection of concerns with inequality and poverty. Key themes that emerge from the papers in this volume include the importance of smallholder farming and land-use practices to questions of environmental sustainability, the dynamic reality of smallholder livelihoods, the challenges of vulnerability and adaptation in contemporary human-environment systems, and the structural and relative nature of the term “smallholder.” Overall these contributions show that smallholder studies are more pertinent than ever, especially in the face of global environmental change. Additionally, we argue that questions of smallholder identity, social difference, and teleconnections provide fertile areas of future research. We conclude that we need to re-envision who the smallholder is today and how this translates into modern human-environment smallholder studies.

    Schwick, H G

    1991-01-01

    At a meeting of the Royal and Imperial Association of Physicians in Vienna on December 18, 1908 Dr. Karl Landsteiner reported on the successful experimental transmission of poliomyelitis from man to ape in a study which he undertook together with Erwin Popper. In a scientific article that was published shortly after the meeting, Landsteiner wrote that "the poliomyelitis virus belongs to the group of filterable micro-organisms". Soon, Landsteiner's results were confirmed by other colleagues. During a congress in Washington 1912 Landsteiner declared that the development of a vaccine against poliomyelitis might prove difficult but was certainly possible in his opinion. It took another 45 years before the first polio vaccine was available (1955 Salk) and another 5 years until the oral vaccine (1960 Sabin) was implemented. The incidence of poliomyelitis decreased dramatically in industrial countries as a result of vaccination. Today, poliomyelitis is still an enormous threat in developing countries. Together with many national and international institutions the WHO fights this situation very hard by means of vaccination campaigns. The incidence of side effects and insufficient reactions is small with both vaccines. New techniques in the field of molecular biology and a good knowledge of the poliovirus make it likely that further improvements on the vaccines which are currently available will take place.

    LaDuke, Rebekah D

    2013-01-01

    The purpose of this article was to review the most current published literature on the topics of academic dishonesty, unethical professional practices, and research that studied the correlation between these 2 areas of interest. Literature was retrieved by utilizing key words such as academic dishonesty, cheating, workplace dishonesty, and unethical behavior. Multiple research databases were used and a reference librarian in locating relevant research studies resulting in 16 research articles reviewed and 7 articles referenced within the literature review. Upon completion, it became apparent that nursing educators should be concerned that nursing students found to be academically dishonest today may have a higher incidence of displaying unethical practices as a registered nurse tomorrow. It also became clear that the nursing profession needs to conduct its own research in this field to verify findings discovered by other professions such as engineering, business, and psychology. Finally, recommendations were given on how nursing educators should handle the topic of ethics in nursing programs. Copyright © 2013 Elsevier Inc. All rights reserved.

  17. Hermeneutics as Embodied Existence

    Directory of Open Access Journals (Sweden)

    Marja Schuster RN, PhD

    2013-02-01

    Full Text Available This article explores the possibilities and limits of a hermeneutic way of being in the world, more specifically being a researcher as a part of human, embodied existence. Understanding existence as embodied highlights the subjectivity of a researcher. For a hermeneutic researcher this subjectivity is both a precondition for interpretation and something that might endanger the scientific endeavour. In this article, I examine the possibilities of combining Hans-Georg Gadamer's empathetic hermeneutics with Paul Ricoeur's critical hermeneutics as a means of both recognizing and, to some extent, controlling my subjectivity in the research process. With Gabriel Marcel I also argue for hermeneutics as an embodied experience. This is exemplified by my study with a focus on the existential dimensions of the nursing profession. The first part of the article introduces Marcel and his philosophical anthropology concerning our bodily existence as essential for shared lives with others. In the second part, this understanding of self and others is further developed by means of the hermeneutics of Gadamer and Ricoeur. In the third part, I present a way of applying hermeneutics in procedures for interviews, transcription, and analysis of data.

    1996-10-01

    In an industry where new power plant planning and budgeting cycles stretch from one to three years, where a typical new generation product takes from five to 10 years to successfully enter the market and where some plants have a 30- to 50-year economic life, change is an evolutionary process. However, that change, driven by the application of new technologies, is inevitable. Twenty-five years ago, in 1971, gas turbines were perceived to have limited applications and were primarily used for part-time peaking duty. Today, they are the baseload, new power generation technology of choice. Nevertheless, more than 55% of the US`s electricity is still generated by coal-fired steam turbine plants, the technology of choice 25 years ago. Power generation technologies will evolve further, but it`s doubtful there will be any new concepts that are not evident in today`s laboratories. Twenty-five years from now, today`s coal-fires team turbine plants will still provide the majority of the electricity generated in the US. However, new natural gas or syngas-fired combined-cycle plants will make up the majority of the new additions, perhaps as much as 20% of the overall installed capacity in 2021. Still, during the next 25 years, a number of new generation technologies should become economically competitive and enter the market. Technologies moving from today`s demonstrations to widespread applications include: gasification, pressurized fluidized bed combustion, fuel cell hybrid cycles, and solar photovoltaics.

  6. Ancient water supports today's energy needs

    The water footprint for fossil fuels typically accounts for water utilized in mining and fuel processing, whereas the water footprint of biofuels assesses the agricultural water used by crops through their lifetime. Fossil fuels have an additional water footprint that is not easily accounted for: ancient water that was used by plants millions of years ago, before they were transformed into fossil fuel. How much water is mankind using from the past to sustain current energy needs? We evaluate the link between ancient water virtually embodied in fossil fuels to current global energy demands by determining the water demand required to replace fossil fuels with biomass produced with water from the present. Using equal energy units of wood, bioethanol, and biodiesel to replace coal, natural gas, and crude oil, respectively, the resulting water demand is 7.39 × 1013 m3 y-1, approximately the same as the total annual evaporation from all land masses and transpiration from all terrestrial vegetation. Thus, there are strong hydrologic constraints to a reliance on biofuel energy produced with water from the present because the conversion from fossil fuels to biofuels would have a disproportionate and unsustainable impact on the modern water. By using fossil fuels to meet today's energy needs, we are virtually using water from a geological past. The water cycle is insufficient to sustain the production of the fuel presently consumed by human societies. Thus, non-fuel-based renewable energy sources are needed to decrease mankind's reliance on fossil fuel energy without placing an overwhelming pressure on global freshwater resources.

    1989-01-01

    The standards of care used in the protection of the health and safety of people exposed to chemicals has increased dramatically in the last decade. Standards imposed by regulation and those adopted by industry have required a greater level of knowledge about the hazards of chemicals. In the E.E.C., the 6th amendment of the dangerous substances directive imposed the requirement that al new chemicals should be tested according to prescribed programme before introduction on to the market. The development of a European inventory of existing chemicals was an integral part of the 6th amendment. It has now become clear that increased standards of care referred to above must be applied to the chemicals on the inventory list. There is, however, a considerable amount of activity already under way in various international agencies. The OECD Chemicals Programme has been involved in considering the problem of existing chemicals for some time, and is producing a priority list and action programme. The International Programme on Chemical Safety produces international chemical safety cards, health and safety guides and environmental health criteria documents. The international register of potentially toxic compounds (part of UNEP) has prepared chemical data profiles on 990 compounds. The International Agency for Research on Cancer prepared monographs on the carcinogenic risk of chemicals to man. So far 42 volumes have been prepared covering about 900 substances. IARC and IPCS also prepare periodic reports on ongoing research on carcinogenicity or toxicity (respectively) of chemicals. The chemical industry through ECETOC (the European Chemical Industry Ecology and Toxicology Centre) has mounted a major initiative on existing chemicals. Comprehensive reviews of the toxicity of selected chemicals are published (Joint Assessment of Commodity Chemicals). In its technical report no. 30 ECETOC lists reviews and evaluations by major national and international organisations, which provides

    We prove that any finite collection of polygons of equal area has a common hinged dissection. That is, for any such collection of polygons there exists a chain of polygons hinged at vertices that can be folded in the plane continuously without self-intersection to form any polygon in the collection. This result settles the open problem about the existence of hinged dissections between pairs of polygons that goes back implicitly to 1864 and has been studied extensively in the past ten years. Our result generalizes and indeed builds upon the result from 1814 that polygons have common dissections (without hinges). We also extend our common dissection result to edge-hinged dissections of solid 3D polyhedra that have a common (unhinged) dissection, as determined by Dehn's 1900 solution to Hilbert's Third Problem. Our proofs are constructive, giving explicit algorithms in all cases. For a constant number of planar polygons, both the number of pieces and running time required by our construction are pseudopolynomial...

    2014-01-01

    Is there one best method to provide instruction to today's nursing students? The evidence found in the current literature clearly states the answer is no. The student of today is technology oriented. But for them, it's not about technology, it's about the learning that technology provides. With this understanding, this article provides a review of the efforts by the staff of the US Army Practical Nurse Course (68WM6) to infuse evidence-based instructional strategies into curriculum. Five strategies that were integrated into the curriculum are presented: computer assisted learning, gaming software, classroom response system, human patient simulators, and video recordings. All of the initiatives discussed in this article were implemented into the program of instruction over a 6-year period in an attempt to incorporate the use of appropriate technology in the learning process. The results are a testimony to the necessity of using a combination of strategies for teaching today's nursing students. In doing so, the organization not only improved the learning process, but found significant financial savings.

    Full Text Available It is well known that the notion of measure and integral were released early enough in close connection with practical problems of measuring of geometric figures. Notion of measure was outlined in the early 20th century through H. Lebesgue’s research, founder of the modern theory of measure and integral. It was developed concurrently a technique of integration of functions. Gradually it was formed a specific area todaycalled the measure and integral theory. Essential contributions to building this theory was made by a large number of mathematicians: C. Carathodory, J. Radon, O. Nikodym, S. Bochner, J. Pettis, P. Halmos and many others. In the following we present several abstract sets, classes of sets. There exists the sets which are not Lebesgue measurable and the sets which are Lebesgue measurable but are not Borel measurable. Hence B ⊂ L ⊂ P(X.

  18. Existence of Minkowski space

    CERN Document Server

    Wagner, Serge

    2016-01-01

    Physics textbooks present Minkowski space as an almost pure mathematical construct, without any explicit restriction on a domain where it is applicable in physics. Meanwhile, its physical meaning cannot but follow the same premises as those which underlies the special relativity theory: motion of free point particles and propagation of electromagnetic waves. However, the common formalism of coordinate transformations between any two inertial frames appears too ponderous to infer the existence of Minkowski space. For this reason, the time dilation and retardation, the contraction of the length along and the spatial invariance across the direction of relative motion of two frames are presented in a coordinate-free manner. This results in the transformation between two frames in the form of relationships between the time moments and the components of the position vector of a given event, along and across the directions of the frames' motion. The obtained transformation rules for the components of the position ve...

    2005-01-27

    Lawrence Livermore National Laboratory's Engineering Directorate has two primary discretionary avenues for its investment in technologies: the Laboratory Directed Research and Development (LDRD) program and the ''Tech Base'' program. This volume summarizes progress on the projects funded for technology-base efforts in FY2004. The Engineering Technical Reports exemplify Engineering's more than 50-year history of researching and developing (LDRD), and reducing to practice (technology-base) the engineering technologies needed to support the Laboratory's missions. Engineering has been a partner in every major program and project at the Laboratory throughout its existence, and has prepared for this role with a skilled workforce and technical resources. This accomplishment is well summarized by Engineering's mission: ''Enable program success today and ensure the Laboratory's vitality tomorrow''. LDRD is the vehicle for creating those technologies and competencies that are cutting edge. These require a significant level of research or contain some unknown that needs to be fully understood. Tech Base is used to apply those technologies, or adapt them to a Laboratory need. The term commonly used for Tech Base projects is ''reduction to practice''. Tech Base projects effect the natural transition to reduction-to-practice of scientific or engineering methods that are well understood and established. They represent discipline-oriented, core competency activities that are multi-programmatic in application, nature, and scope. The objectives of technology-base funding include: (1) the development and enhancement of tools and processes to provide Engineering support capability, such as code maintenance and improved fabrication methods; (2) support of Engineering science and technology infrastructure, such as the installation or integration of a new capability; (3) support for technical and

    2016-01-01

    Federal directives, nursing and nursing education associations, as well as accrediting bodies emphasize the importance of integrating health information technology and EHRs into nursing practice. Additionally, informatics is a required competency of baccalaureate nursing graduates. Nursing education's efforts to enhance students' learning in the area of electronic documentation is at its peak. The goal of enabling nurses to make healthcare safer, more effective, efficient, patient-centered, timely and equitable can only be achieved if a variety of technologies are clearly integrated into nursing education. Therefore, some schools have developed educational innovations to incorporate academic EHRs. As the mental health setting is unique, extraordinary attention has to be provided during the education of electronic documentation. Nursing education efforts must focus on interventions that provide resources that enhance the participant's knowledge and skills related to electronic documentation in a variety of clinical settings. Additionally, implementing academic EHRs in clinical settings offers nursing educators an opportunity to note the benefits. The state of nursing education depends on the accessibility to utilize academic EHRs in the nursing curriculum within the clinical setting to effectively prepare students for real-word practice.

    One of the greatest challenges to modern technologies is what to do with them when they go irreparably wrong or come to the end of their productive lives. The convention, since the development of modern civilisation, is to discard a broken item and then procure a new one. In the 20th century enlightened environmentalists campaigned for recycling and reuse (R and R). R and R has continued to be an important part of new technology development, but there is still a huge problem of non-recyclable materials being dumped into landfill and being discarded in the environment. The challenge is even greater for robotics, a field which will impact on all aspects of our lives, where discards include motors, rigid elements and toxic power supplies and batteries. One novel solution is the biodegradable robot, an active physical machine that is composed of biodegradable materials and which degrades to nothing when released into the environment. In this paper we examine the potential and realities of biodegradable robotics, consider novel solutions to core components such as sensors, actuators and energy scavenging, and give examples of biodegradable robotics fabricated from everyday, and not so common, biodegradable electroactive materials. The realisation of truly biodegradable robots also brings entirely new deployment, exploration and bio-remediation capabilities: why track and recover a few large non-biodegradable robots when you could speculatively release millions of biodegradable robots instead? We will consider some of these exciting developments and explore the future of this new field.

    The report consists of three chapters and four appendices. Chapter 1 provides basic information on the role of storage in today`s marketplace where natural gas is treated as a commodity. Chapter 2 provides statistical analyses of the relationship between storage and spot prices on both a monthly and daily basis. For the daily analysis, temperature data were used a proxy for storage withdrawals, providing a new means of examining the short-term relationship between storage and spot prices. Chapter 3 analyzes recent trends in storage management and use, as well as plans for additions to storage capacity. It also reviews the status of the new uses of storage resulting from Order 636, that is, market-based rates and capacity release. Appendix A serves as a stand-along primer on storage operations, and Appendix B provides further data on plans for the expansion of storage capacity. Appendix C explains recent revisions made to working gas and base gas capacity on the part of several storage operators in 1991 through 1993. The revisions were significant, and this appendix provides a consistent historical data series that reflects these changes. Finally, Appendix D presents more information on the regression analysis presented in Chapter 2. 19 refs., 21 figs., 5 tabs.

    At the end of the 19th century, the Society for the Prevention of Cruelty to Children was founded in New York, after a barbarous case of neglect and abuse of a girl became public. From then on, children received more and more protection. Only in the 1950s were doctors in the USA bound by law to report cases of putative physical abuse to officials. In Sweden, physical punishment of children has been forbidden since 1989, and in Germany since 2001. The existence of sexual abuse of children had been a taboo subject for centuries, even though individual attempts to break that taboo were made--e. g., by S. Freud in the theory of seduction (Verführungstheorie). Only with the birth of the women's liberation movement in the early 1970s has public awareness arisen. Due to the work of J. Bowlby in the 1950s, it became clear that children of primates need more than air, water and food, namely a relationship between the child and an adult person (attachment). To what degree the basic needs of children are being fulfilled in Western societies today is still a controversial issue.

  6. Future Warming Patterns Linked to Today's Climate Variability.

    The reliability of model projections of greenhouse gas (GHG)-induced future climate change is often assessed based on models' ability to simulate the current climate, but there has been little evidence that connects the two. In fact, this practice has been questioned because the GHG-induced future climate change may involve additional physical processes that are not important for the current climate. Here I show that the spatial patterns of the GHG-induced future warming in the 21(st) century is highly correlated with the patterns of the year-to-year variations of surface air temperature for today's climate, with areas of larger variations during 1950-1979 having more GHG-induced warming in the 21(st) century in all climate models. Such a relationship also exists in other climate fields such as atmospheric water vapor, and it is evident in observed temperatures from 1950-2010. The results suggest that many physical processes may work similarly in producing the year-to-year climate variations in the current climate and the GHG-induced long-term changes in the 21(st) century in models and in the real world. They support the notion that models that simulate present-day climate variability better are likely to make more reliable predictions of future climate change.

A Team of university, NASA, and industry investigators will conduct the study to determine the full sensitivity and capabilities of this new configuration for EXIST. It will build on the extensive studies of the prior design for the mission and the HET and will incorporate the optical/IR telescope (hereafter IRT) now fully developed by our ITT partner for the NextView Commercial Remote Sensing mission (early 2008 launch) with a focal plane to be developed at GSFC based in part on JWST/NIRSPEC designs. No new technology is needed for either the IRT or HET instruments. The study will pay close attention to full mission cost and present a design for the Decadal Survey Workshop to ensure this even more capable EXIST mission is once again part of the next Decadal Survey.

    Martinsen, Elin Håkonsen; Solbakk, Jan Helge

    2012-06-01

    This paper seeks to find different ways of addressing illness as an experience essential to the understanding of being a human being. As a conceptual point of departure, we suggest the notion of 'pathic existence' as developed by the German physician and philosopher Viktor von Weizsäcker (1886-1957). Through an analysis of his conceptualisation of the pathic and of pathic categories, we demonstrate how this auxiliary typology may be of help in unveiling different modes of ill-being, or Kranksein. Furthermore, we show how illness plays a paradigmatic role in this type of existence. We discuss how von Weizsäcker's claim of illness as "a way of being human" indicates how such a view of the illness existence both differs from and touches upon other streams of thought within the philosophy of medicine and medical ethics. Finally, we highlight some of the normative implications emerging from this perspective of relevance in today's medicine.

    Reid, Concha M.

    2015-01-01

    NASA uses batteries for virtually all of its space missions. Batteries can be bulky and heavy, and some chemistries are more prone to safety issues than others. To meet NASA's needs for safe, lightweight, compact and reliable batteries, scientists and engineers at NASA develop advanced battery technologies that are suitable for space applications and that can satisfy these multiple objectives. Many times, these objectives compete with one another, as the demand for more and more energy in smaller packages dictates that we use higher energy chemistries that are also more energetic by nature. NASA partners with companies and universities, like Xavier University of Louisiana, to pool our collective knowledge and discover innovative technical solutions to these challenges. This talk will discuss a little about NASA's use of batteries and why NASA seeks more advanced chemistries. A short primer on battery chemistries and their chemical reactions is included. Finally, the talk will touch on how the work under the Solid High Energy Lithium Battery (SHELiB) grant to develop solid lithium-ion conducting electrolytes and solid-state batteries can contribute to NASA's mission.

    Full Text Available The fuel cell has some characteristics of a battery carrying out direct chemical conversion into electric energy. In relation to classical systems used for chemical energy conversion into electric power, through heat energy and mechanical operation, the fuel cell has considerably higher efficiency. The thermo-mechanical conversion of chemical into electric energy, in thermal power plants is carried out with 30% efficiency, while the efficiency of chemical conversion into electric energy, using a fuel cell is up to 60%. With the exception of the space programme, the commercial usage of the fuel cell did not exist up to 1990, when the most developed countries started extensive financial support of this source of energy. By 1995, more than a hundred fuel cells were installed in the process of electricity generation in Europe, USA and Japan, while nowadays there are thousands of installations, of efficient energetic capacity. Because of its superior characteristics, the fuel cell compared to other commercial electric energy producers, fulfills the most important condition - it does not pollute or if it does, the level is minimal. With such characteristics the fuel cell can help solve the growing conflict between the further economic development of mankind and the preservation of a clean and healthy natural environment.

    Vaccination is a complex ecosystem with several components that interact with one another and with the environment. Today's vaccine ecosystem is defined by the pursuit of polio eradication, the drive to get as many of the new vaccines to as many people as possible and the research and development against immunologically challenging diseases. Despite these successes, vaccine ecosystem is facing keys issues with regard to supply/distribution and cost/profitability asymmetry that risk slowing its global growth. The conference "Vaccination ecosystem health check: achieving impact today and sustainability for tomorrow" held in Annecy-France (January 19-21, 2015) took stock of the health of today's vaccination ecosystem and its ability to reliably and sustainably supply high-quality vaccines while investing in tomorrow's needed innovation. Small and decreasing numbers of suppliers/manufacturing facilities; paucity of research-driven companies; regulatory pressures; market uncertainties; political prioritization; anti-vaccine movements/complacency; and technological and programmatic issues were acknowledged as the major challenges that could weaken today's vaccination ecosystem. The expert panel discussed also drivers and barriers to a sustainable vaccination ecosystem; the metrics of a vaccination ecosystem; and what should be added, removed, increased, or reduced to maintain the health of the vaccination ecosystem.

    1993-04-01

    Freud's "Civilization and its Discontents" (1930) serves the author as a point of departure for socio-psychological hypotheses that go beyond the biologistic bias of the late Freudian concept of drive and its approach to the subject in terms of the antagonism of eros and thantos and essay a concrete historical and social diagnosis of present-day "discontent" with our civilization. The view taken by Busch is indebted to the work of Klaus Horn and Alfred Lorenzer, regarding "discontent" as the result of a failed socialisation process of an internal nature, the expression of "damaged subjectivity". Like Freud before him, Busch speculates on the chances for the emergence of a "constitutional intolerance" not only towards war in the traditional sense but also towards the species of war that represents the major threat to mankind today: the technological and industrial warfare waged against the natural foundations of the very existence of homo sapiens on this planet.

    Biocuration is a time-intensive process that involves extraction, transcription, and organization of biological or clinical data from disjointed data sets into a user-friendly database. Curated data is subsequently used primarily for text mining or informatics analysis (bioinformatics, neuroinformatics, health informatics, etc.) and secondarily as a researcher resource. Biocuration is traditionally considered a Ph.D. level task, but a massive shortage of curators to consolidate the ever-mounting biomedical "big data" opens the possibility of utilizing biocuration as a means to mine today's data while teaching students skill sets they can utilize in any career. By developing a biocuration assembly line of simplified and compartmentalized tasks, we have enabled biocuration to be effectively performed by a hierarchy of undergraduate students. We summarize the necessary physical resources, process for establishing a data path, biocuration workflow, and undergraduate hierarchy of curation, technical, information technology (IT), quality control and managerial positions. We detail the undergraduate application and training processes and give detailed job descriptions for each position on the assembly line. We present case studies of neuropathology curation performed entirely by undergraduates, namely the construction of experimental databases of Amyotrophic Lateral Sclerosis (ALS) transgenic mouse models and clinical data from ALS patient records. Our results reveal undergraduate biocuration is scalable for a group of 8-50+ with relatively minimal required resources. Moreover, with average accuracy rates greater than 98.8%, undergraduate biocurators are equivalently accurate to their professional counterparts. Initial training to be completely proficient at the entry-level takes about five weeks with a minimal student time commitment of four hours/week.

    Evidence shows that both biological and nonbiological factors contribute to health disparities. Genetics, in particular, plays a part in how common diseases manifest themselves. Today, unprecedented advances in genetically based diagnoses and treatments provide opportunities for personalized medicine. However, disadvantaged groups may lack access to these advances, and treatments based on research on non-Hispanic whites might not be generalizable to members of minority groups. Unless genetic technologies become universally accessible, existing disparities could be widened. Addressing this issue will require integrated strategies, including expanding genetic research, improving genetic literacy, and enhancing access to genetic technologies among minority populations in a way that avoids harms such as stigmatization.

  16. Biology as technology.

    Science.gov (United States)

    Bayertz, K; Nevers, P

    1998-01-01

    In this paper we have emphasised the technological dimension of the biosciences, especially the biosciences of our time. As a straight forward fact this dimension is less controversial than the question of its relevance is. We have argued that the existence of this dimension is a consequence of the empirical character of the biosciences (as well as of the sciences in general). Knowledge of nature can be achieved only if the subject of knowledge is able to gain access to natural phenomena, and technological means have become increasingly necessary for achieving this. The more that is already known, the greater the technological investment required to produce new knowledge. Therefore there is an interrelationship between the advancement of knowledge and the amount and complexity of the research technology required. It would be short sighted to conclude from this observation that human imagination and inventiveness have become superfluous. Nevertheless the growing preponderance of technological means for progress in science is undeniable. A particularly important insight is that this process not only involves a quantitative increase in technology within science. Our main hypothesis is that there is a close relationship between the type of means used, the type of subject required for performing research, the kinds of objects investigated in science, and the nature of the results that are generated. We have tried to illustrate this by distinguishing between three different types of bioscience: (a) a descriptive type, (b) an experimental type, and (c) and an industrial type. Without pretending this provides a universal key to the history of the biosciences and to understanding of the way science works today, we hope that such a distinction may open up new avenues of thought. We hope that this approach will provide us with a more realistic picture of science. The propositional view reduces science to its theoretical results, in particular to the theories emanating from

    We describe the detector development for a balloon-borne wide-field hard X-ray (20 - 600 keV) telescope, ProtoEXIST. ProtoEXIST is a pathfinder for both technology and science of the proposed implementation of the Black Hole Finder Probe, Energetic X-ray Imaging Survey telescope (EXIST). The principal technology challenge is the development of large area, close-tiled modules of imaging CZT detectors (1000 cm2 for ProtoEXIST1). We review the updates of the detector design and package concept for ProtoEXIST1 and report the current development status of the CZT detectors, using calibration results of our basic detector unit - 2 x 2 x 0.5 cm CZT crystals with 2.5 mm pixels (8 x 8 array). The current prototype (Rev1) of our detector crystal unit (DCU) shows ~4.5 keV electronics noise (FWHM), and the radiation measurements show the energy resolution (FWHM) of the units is 4.7 keV (7.9%) at 59.5 keV, 5.6 keV (4.6%) at 122 keV, and 7.6 keV (2.1%) at 356 keV. The new (Rev2) DCU with revised design is expected to impro...

  1. Sustainable vehicle fuels - Do they exist?

    Energy Technology Data Exchange (ETDEWEB)

    Boerjesson, Paal; Ericsson, Karin; Di Lucia, Lorenzo; Nilsson, Lars J.; Aahman, Max

    2009-03-15

    Our aim with this report is to discuss vehicle fuels from a wide perspective of sustainability. Biofuels and electricity are analyzed and compared to fossil vehicle fuels. Our goal is to try to point out the circumstances under which vehicle fuels can be reasonably perceived as sustainable, and which systems we should develop and which we should avoid. The all-embracing conclusion of this study is that one can not establish how sustainable fuels will develop in the future without simultaneously taking into consideration both scale and pace of growth. Today's biofuels produced in Sweden are sustainable, given the present production volume, and promote further development of new fuel systems. However, in the case of increased production volumes, exact requirements should be established for the energy- and climate efficiency of the entire fuel chain (from cultivation to tank). High priority should be given to the development of fuel-efficient cars. In this field hybrid electric technology and electric cars will grow in importance. Any long-term strategy for biofuels should include investments in technology for both thermal gasification and biological conversion methods of lignocellulose, since these are complementing as much as competing technologies, both increasing the flexibility as well as decreasing the risk of conflicts. Biogas from waste products has great environmental advantages and the sector can be expanded with only small risks of conflicts. Certification (if correctly formulated) is an important and necessary tool on the way towards more sustainable vehicle fuels and increased production volumes, but certification systems should not be overrated since they can not cover all sustainability aspects. Socio-economic aspects such as working conditions, local rural development etc. must be dealt with through general measures such as national laws, distribution policies, programs and plans, all of which should be supported by international agreements and

    2015-01-01

    Articular cartilage injury is prevalent in football players and results from chronic joint stress or acute traumatic injuries. Articular cartilage injury can often result in progressive painful impairment of joint function and limit sports participation. Management of articular cartilage injury in athletes aims to return the player to competition, and requires effective and durable joint surface restoration that resembles normal hyaline articular cartilage that can withstand the high joint stresses of football. Existing articular cartilage repair techniques can return the athlete with articular cartilage injury to high-impact sports, but treatment does not produce normal articular cartilage, and this limits the success rate and durability of current cartilage repair in athletes. Novel scientific concepts and treatment techniques that apply modern tissue engineering technologies promise further advancement in the treatment of these challenging injuries in the high demand athletic population. We review the current knowledge of cartilage injury pathophysiology, epidemiology and aetiology, and outline existing management algorithms, developing treatment options and future strategies to manage articular cartilage injuries in football players.

    With limited low-load options in the HVAC market, many new-construction housing units are being fitted with oversized equipment - thus facing penalties in system efficiency, comfort, and cost. To bridge the gap between currently available HVAC equipment and the rising demand for low-load HVAC equipment in the marketplace, HVAC equipment manufacturers need to be fully aware of multifamily buildings and single-family homes market needs. Over the past decade, Steven Winter Associates, Inc. (SWA) has provided certification and consulting services on hundreds of housing projects and has accrued a large pool of data. CARB compiled and analyzed these data to see what the thermal load ranges are in various multifamily apartments and attached single-family home types (duplex and townhouse). In total, design loads from 941 dwellings from SWA's recent multifamily and attached single-family work across the Northeast and Mid-Atlantic were analyzed. Information on the dwelling characteristics, design loads, and the specifications of installed mechanical equipment were analyzed to determine any trends that exist within the dataset. Of the 941 dwellings, CARB found that only 1% had right-sized heating equipment and 6% of the dwellings had right-sized cooling equipment (within 25% or less of design load).

  18. Speckle metrology in the nanoworld, as it is perceived today, and how it may affect industry

    Science.gov (United States)

    Pryputniewicz, Ryszard J.

    2010-09-01

    My memory goes back to my early collage studies that were almost entirely on the scale of "macroworld", as we practiced/perceived it some four decades ago. Since that time things have changed a lot constantly decreasing the scales of interest, at times at rather rapid pace, with monumental advances leading to the scales we work with today and plan for tomorrow. During that change/transition there were "meso" and "micro" developments characterized by changes in scales/sizes of things of interest. Today's scale of interest is "nano" and we are already not only working with "picotechnology", but are even reaching beyond while constantly "planning and projecting" the scales/worlds of the future. Advancement of any technology, especially new emerging ones as we witness/experience them today, is facilitated by the use of all available solution strategies. One of the emerging strategies that affect almost anything currently being developed and/or used, in the today's nanoworld, is based on recent advances of microelectromechanical systems (MEMS). Today MEMS affect almost everything we do from household appliances, via cars we drive and planes that whisk us from continent to continent, to spaceships used for search of/and exploration of other worlds. The modern microsensors are also used to explore for and produce petroleum products that are used in multitude of today's applications. To facilitate these advances a great majority of MEMS is used in the form of sensors. However development of MEMS in general and sensors in particular poses one of the greatest challenges in today's experimental mechanics. Among MEMS, the greatest contemporary interest is in the area of inertial sensors because they have numerous uses ranging from everyday applications to highly specialized ones, including many industrial platforms. As such they have tremendous potential to affect future of humanity. However, advances in MEMS, such as pressure and temperature sensors as well as gyroscopes and

    Diderichsen, F

    1982-01-01

    Sweden has a long tradition of social democracy and corporate cooperation. Social problems are treated as technological questions that always should be solved through rational and neutral means. Today Sweden faces a crisis of economy as well as a crisis of medicine. In the spirit of consensus, the state has proposed a new health reform emphasizing the responsibility of the public health service to prevent disease and provide equal access to care. It is claimed that improved health planning, based on epidemiological knowledge on inequalities, can solve the crisis in medicine within an improved system of primary care and prevention. However, in the context of the current economic crisis, the struggle against health hazards and cuts in public spending has intensified and the gap between the ideology of technological rationalism and reality has widened.

    Changes in the clinical learning environment under resident duty hours restrictions have introduced a number of challenges on today's wards. Additionally, the current group of medical trainees is largely represented by the Millennial Generation, a generation characterized by an affinity for technology, interaction, and group-based learning. Special attention must be paid to take into account the learning needs of a generation that has only ever known life with duty hours. A mnemonic for strategies to augment teaching rounds for hospitalists was created using an approach that considers time limitations due to duty hours as well as the preferences of Millennial learners. These strategies to enhance learning during teaching rounds are Flipping the Wards, Using Documentation to Teach, Technology-Enabled Teaching, Using Guerilla Teaching Tactics, Rainy Day Teaching, and Embedding Teaching Moments into Rounds (FUTURE). Hospitalists serving as teaching attendings should consider these possible strategies as ways to enhance teaching in the post-duty hours era. These techniques appeal to the preferences of today's learners in an environment often limited by time constraints. Hospitalists are well positioned to champion innovative approaches to teaching in a dynamic and evolving clinical learning environment. © 2013 Society of Hospital Medicine.

    Full Text Available Temas como aquilo que há; o ser na sua singularidade (independentemente dos seus atributos ou das contingências; a relação entre escolha, necessidade e acaso; a relação entre possibilidade e impossibilidade (ou mesmo possíveis impossibilidades; e, por fim, neste ensaio, a relação entre caos e sistemas de ordem, sempre estiveram presentes, tanto na criação lírica como na reflexão filosófica. Logo, a existência não é privilégio do existencialismo. A noção de existência forma-se a partir daqueles temas: ela é secundária em relação aos pensamentos que a determinam. Trata-se, portanto, de uma “longa história, esta do sentido da existência” (DELEUZE, 1985. Desde o pensamento que se forma de uma culpa, desde o ressentimento e da vingança em torno da injustiça permanente do devir (quando a existência torna-se modificada pelos predicados, ou seja, niilista, à negação do todo e à absolvição da existência pela sua inocência (isto é, a afirmação do devir, o eterno retorno do ser do devir, etc., a noção de existência se desdobra. Sendo assim, o título deste trabalho, ao suspender aqueles sentidos estabelecidos, busca capturar a existência desde a potencialidade de suas relações com as configurações do poético.

    2012-08-01

    Full Text Available This paper will examine key technologies that exist in the market today which can be used to enable instructor content curation and idea growth through direct student collaboration. Existing tools can be used to not only recreate the in-class collaborative experience in a distance-learning environment, but can also be used to support growing collections of knowledge on topics/subjects than just what can be gained from a single class or semester. This paper envisions a method for both instructors and students to help them effectively curate content and helps empower them to communicate through references to a combination of text and digital media. These references originate from multiple platforms across the Web, but relate to a single topic or idea. This “compilation” of material can then be treated as its own form of content and can be assignable, consumable, and gradable in the well-established pedagogy of standard learning management systems. This form of content would allow instructors or students to present ideas that are greater than the sum of their individual parts and provide a platform for further discussion and learning, ultimately, growing the value of the content itself.

    2015-01-01

    Vulnerability eradication has become an emerging concern in today's society following the increasing uncertainties in achieving societal resilience, particularly in vulnerable communities. Furthermore, incorporating technological solution, especially appropriate technology (AT), into such concern requires interdisciplinary understandings to achieve a holistic eradication based on the particularities of each community. This study aims to briefly reveal existing scholarly discourses and investigate potential gap(s) between previous researches. Literatures, particularly consisting meta-analysis on previous scholarly discussions, are surveyed. The findings reveal three progress among scientific discourses. The first one is the paradigm shift of developmental purposes from typical development to empowerment. Next, concerns in technology development indicate the parallel movement toward empowerment. Then, previous methodological developments, including approach in sustaining AT, indicate the needs to assess the future based on sustainability. Therefore, a new research is proposed to develop an assessment framework on AT for vulnerability eradication on the basis of empowerment paradigm, extended focuses in technology development, and extended coverage of future changes in dynamic matter. The framework needs to be developed based on the combination of positivist-deductive-qualitative research paradigms. This is intended to generalize the framework for being used in different cases, to build an applicative framework as an integral part of existing body of knowledge, and to develop an enriched and flexible construction of framework. Looking at existing researches, this brief study proposes insights to move scientific progress toward a more holistic vulnerability eradication using AT solution both in conceptual and practical levels.

    Geller, Harold A.

    2014-01-01

    I will discuss my research into the issues associated with the nature of any extraterrestrials that may be encountered in the future in our galaxy. This research was sparked by statements made by Stephen Hawking in 2010 regarding his fear of emitting radiation from our Earth so that an extraterrestrial intelligent civilization may be alerted to our existence in the galaxy today. While addressing issues of extraterrestrial altruism, a probabilistic equation was developed which addresses the number of extraterrestrial intelligent life forms that may exist in our galaxy today, who could use our bodies for nourishment or reproductive purposes. The equation begins with the results from a Drake Equation calculation, and proceeds by addressing such biochemical parameters as the fraction of ETIs with: dextro sugar stereo-isomers; levo amino acid stereo-isomers; similar codon interpretation; chromosomal length and, similar cell membrane structure to allow egg penetration.

  15. Existing Steel Railway Bridges Evaluation

    Vičan, Josef; Gocál, Jozef; Odrobiňák, Jaroslav; Koteš, Peter

    2016-12-01

    The article describes general principles and basis of evaluation of existing railway bridges based on the concept of load-carrying capacity determination. Compared to the design of a new bridge, the modified reliability level for existing bridges evaluation should be considered due to implementation of the additional data related to bridge condition and behaviour obtained from regular inspections. Based on those data respecting the bridge remaining lifetime, a modification of partial safety factors for actions and materials could be respected in the bridge evaluation process. A great attention is also paid to the specific problems of determination of load-caring capacity of steel railway bridges in service. Recommendation for global analysis and methodology for existing steel bridge superstructure load-carrying capacity determination are described too.

    Biomass derived energy currently accounts for about 3 quads of total primary energy use in the United States. Of this amount, about 0.8 quads are used for power generation. Several biomass energy production technologies exist today which contribute to this energy mix. Biomass combustion technologies have been the dominant source of biomass energy production, both historically and during the past two decades of expansion of modern biomass energy in the U. S. and Europe. As a research and development activity, biomass gasification has usually been the major emphasis as a method of more efficiently utilizing the energy potential of biomass, particularly wood. Numerous biomass gasification technologies exist today in various stages of development. Some are simple systems, while others employ a high degree of integration for maximum energy utilization. The purpose of this study is to conduct a technical and economic comparison of up to three biomass gasification technologies, including the carbon dioxide emissions reduction potential of each. To accomplish this, a literature search was first conducted to determine which technologies were most promising based on a specific set of criteria. The technical and economic performances of the selected processes were evaluated using computer models and available literature. Using these results, the carbon sequestration potential of the three technologies was then evaluated. The results of these evaluations are given in this final report.

    2010版药品GMP较1998版药品GMP新增了隔离操作技术方面的内容,极大地推动了隔离操作技术在我国制药行业的应用。目前,很多制药企业在实施2010版药品GMP过程中,已经开始积极使用隔离操作技术。但是,也存在很多问题,包括设计缺陷、人员培训不到位、文件可操作性不强、确认工作不充分、忽视日常维护、对隔离操作技术持消极态度等。针对这些问题,建议制药企业从设计源头把关,加强人员培训,细化文件,完善确认工作,完善日常维护,重视隔离操作技术的应用。制药企业在使用该项技术的过程中,要坚持因地制宜、软硬并重的原则。%Compared with 1998 Edition Drug GMP, in 2010 Edition one, restricted access barrier technology was newly added, by which the application of this new technology had been greatly promoted. Currently restricted access barrier technology has been applied in many pharmaceutical enterprises in execution of 2010 Edition Drug GMP. But there exists some problems, including defects in design, deifciency in personnel training, weak operability of documents, not full approval for the performances, without attentions to routine maintenance and passive attitude to this technology. With respect to these problems, it was proposed in this article that pharmaceutical enterprises should grasp the design as a beginning, strengthen personnel training, prepare the documents in detail, improve the approval work and routine maintenance, and pay attention to the application of restricted access barrier technology. In the application of this technology, it shall be follow the rules that the application of this technology should be adapted to local situation, and both hardware and software be taken into the same account.

    Due to the experience in the exploitation of previous European telemedicine projects an open Euro-Mediterranean consortium proposes the Virtual Euro-Mediterranean Hospital (VEMH) initiative. The provision of the same advanced technologies to the European and Mediterranean Countries should contribute to their better dialogue for integration. VEMH aims to facilitate the interconnection of various services through real integration which must take into account the social, human and cultural dimensions. VEMH will provide a platform consisting of a satellite and terrestrial link for the application of medical e-learning, real-time telemedicine and medical assistance. The methodologies for the VEMH are medical-needs-driven instead of technology-driven. They supply new management tools for virtual medical communities and allow management of clinical outcomes for implementation of evidence-based medicine. Due to the distributed character of the VEMH Grid technology becomes inevitable for successful deployment of the services. Existing Grid Engines provide basic computing power needed by today's medical analysis tasks but lack other capabilities needed for communication and knowledge sharing services envisioned. When it comes to heterogeneous systems to be shared by different institutions especially the high level system management areas are still unsupported. Therefore a Metagrid Engine is needed that provides a superset of functionalities across different Grid Engines and manages strong privacy and Quality of Service constraints at this comprehensive level.

    Pre-existence probability of the fragments for the complete binary spectrum of different systems such as {sup 56}Ni, {sup 116}Ba, {sup 226}Ra and {sup 256}Fm are calculated, from the overlapping part of the interaction potential using the WKB approximation. The role of reduced mass as well as the classical hydrodynamical mass in the WKB method is analysed. Within WKB, even for negative Q -value systems, the pre-existence probability is calculated. The calculations reveal rich structural information. The calculated results are compared with the values of preformed cluster model of Gupta and collaborators. The mass asymmetry motion is shown here for the first time as a part of relative separation motion. (orig.)

    Employees today want more out of a job than a big salary. Workers' expectations have shifted over the past few decades. Employers need to recognize five key changes in workers' expectations, namely that they want to lead balanced lives, enjoy partnership with their employers, receive opportunities for personal and professional growth, be able to make a meaningful contribution to the world through their work, and experience opportunities to socialize at work. Healthcare organizations that want to attract and retain the employees that they need can achieve competitive advantage in the marketplace by responding to these new work values.

    There are about 180,000 elevators in Switzerland. It is interesting to know how much energy those elevators are using and to know their saving potential, if they would optimally use today's available technology. A previous final report (SFOE reference number 250057) has answered these questions. The results have been used in the work for the directive VDI 4707, which defines an energy label for elevators. It can therefore be assumed that a means has been created to have the necessary pressure to continuously improve the energy efficiency of elevators. Since elevators are products with very long lifetime, it will take a couple of decades until the older less efficient elevators got replaced by modern efficient ones. Modernizing elevators is a common practice, where usually modern drive solutions are sold. During the last years, the elevator industry has made high progress in improving the efficiency in the operation. The lack of awareness and the regulatory requirements have continuously increased the standby power. There are no solutions on the market to minimize the standby although 70% of the energy used by elevators in Switzerland count for the standby. Therefore this study has set the target to optimize the standby for existing elevators. The focus has been set to a solution being manufacturer and technology neutral, since the technology and product variations are huge. Using a standby-reduction-device, this study tries to automatically switch off complete elevators from the mains and on demand turns them on again. The study shows the problems faced, the solution chosen and the possible saving potential.

    Biomass derived energy currently accounts for about 3 quads of total primary energy use in the United States. Of this amount, about 0.8 quads are used for power generation. Several biomass energy production technologies exist today which contribute to this energy mix. Biomass combustion technologies have been the dominant source of biomass energy production, both historically and during the past two decades of expansion of modern biomass energy in the U. S. and Europe. As a research and development activity, biomass gasification has usually been the major emphasis as a method of more efficiently utilizing the energy potential of biomass, particularly wood. Numerous biomass gasification technologies exist today in various stages of development. Some are simple systems, while others employ a high degree of integration for maximum energy utilization. The purpose of this study is to conduct a technical and economic comparison of up to three biomass gasification technologies, including the carbon dioxide emissions reduction potential of each. To accomplish this, a literature search was first conducted to determine which technologies were most promising based on a specific set of criteria. During this reporting period, the technical and economic performances of the selected processes were evaluated using computer models and available literature. The results of these evaluations are summarized in this report.

  8. Saddle scars Existence and applications

    Mendes, R V

    1998-01-01

    A quantum scar is a wave function which displays an high intensity in the region of a classical unstable periodic orbit. Saddle scars are states related to the unstable harmonic motions along the stable manifold of a saddle point of the potential. Using a semiclassical method it is shown that, independently of the overall structure of the potential, the local dynamics of the saddle point is sufficient to insure the general existence of this type of scars and their factorized structure is obtained. Potentially useful situations are identified, where these states appear (directly or in disguise) and might be used for quantum control purposes.

    Society as a whole is increasingly exposed and vulnerable to natural disasters due to extreme weather events exacerbated by climate change. The increased frequency of wildfires is not only a result of a changing climate, but wildfires themselves also produce a significant amount of greenhouse gases that, in-turn, further contribute to global warming. I-REACT (Improving Resilience to Emergencies through Advanced Cyber Technologies) is an innovation project funded by the European Commission , which aims to use social media, smartphones and wearables to improve natural disaster management by integrating existing services, both local and European, into a platform that supports the entire emergency management cycle. In order to assess the impact of climate change on wildfire hazards, METEOSIM designed two different System Processes (SP) that will be integrated into the I-REACT service that can provide information on a variety of time scales. SP1 - Climate Change Impact The climate change impact on climate variables related to fires is calculated by building an ensemble based on the Coupled Model Intercomparison Project Phase 5 (CMIP5) and CORDEX data. A validation and an Empirical-Statistical Downscaling (ESD) calibration are done to assess the changes in the past of the climatic variables related to wildfires (temperature, precipitation, wind, relative humidity and Fire Weather Index). Calculations in the trend and the frequency of extreme events of those variables are done for three time scales: near-term (2011-2040), mid-term (2041-2070) and long term (2071-2100). SP2 - Operational daily forecast of the Canadian Forest Fire Weather Index (FWI) Using ensemble data from the ECMWF and from the GLAMEPS (multi-model ensemble) models, both supplied by the Finnish Meteorological Institute (FMI), the Fire Weather Index (FWI) and its index components are produced for each ensemble member within a wide forecast time range, from a few hours up to 10 days resulting in a

    The Declaration of Alma Ata, issued on September 12, 1978, provides a moral vision for primary care that remains valuable today at a time of transformation of the specialty of family medicine. The Declaration asserts a comprehensive definition of health that recognizes health as a fundamental human right, argues persuasively that gross inequalities in health status are politically, socially, and economically unacceptable, and identifies primary health care as the key to improving health and reducing health status inequalities. The values of Alma Ata can guide the specialty of family medicine to lead positive health system change through renewed collaboration, addressing inequalities, efficient use of resources and appropriate technology, and advocacy in the spirit of social justice.

    Increased outbreaks of food-borne illnesses, including deaths in recent years, attributed in large part to consumption of food contaminated with Escherichia coli O157:H7, have become a worldwide concern. Food-borne illnesses constitute an unacceptable health risk demanding stringent food safety controls. Despite food irradiation being a known effective method to eliminate pathogens that are difficult to eradicate by conventional methods, consumers and industry at large have been reluctant to adopt it. This is mainly attributed to some apprehensions regarding the safety of irradiated food. One such apprehension relates to 2-alkylcylcyclobutanones, unique radiolytic products thought to be formed in minute quantities in food during radiation processing. We demonstrate here for the first time the natural occurrence of 2-dodecylcyclobutanone and 2-tetradecylcyclobutanone in commercial nonirradiated as well as fresh cashew nut samples and 2-decylcyclobutanone as well as 2-dodecylcyclobutanone in nonirradiated nutmeg samples. The presence of 2-tetradecenylcyclobutanone was also observed in both commercial and irradiated cashew nuts. The present study will provide greater impetus for wider adoption of radiation technology for elimination of food-borne pathogenic bacteria without apprehensions about the technology that can help ensure food safety.

  13. Turbulence: does energy cascade exist?

    CERN Document Server

    Josserand, Christophe; Lehner, Thierry; Pomeau, Yves

    2016-01-01

    To answer the question whether a cascade of energy exists or not in turbulence, we propose a set of correlation functions able to test if there is an irreversible transfert of energy, step by step, from large to small structures. These tests are applied to real Eulerian data of a turbulent velocity flow, taken in the wind grid tunnel of Modane, and also to a prototype model equation for wave turbulence. First we demonstrate the irreversible character of the flow by using multi-time correlation function at a given point of space. Moreover the unexpected behavior of the test function leads us to connect irreversibility and finite time singularities (intermittency). Secondly we show that turbulent cascade exists, and is a dynamical process, by using a test function depending on time and frequency. The cascade shows up only in the inertial domain where the kinetic energy is transferred more rapidly (on average) from the wavenumber $k_{1}$ to $k_{2}$ than from $k_{1}$ to $k'_{2}$ larger than $k_{2}$.

    Shortage in mineral oil and gas as well as a high price level have caused a renaissance in coal conversion technologies, at the end of the 70's. Today we have a similar situation. Now coal coversion technologies will be in the focus again but hopefully as a longterm strategy. The most important coal conversion technologies as liquefaction, gasification, coking and calcium carbide synthesis are discussed regarding their use for the production of chemicals. The most important source for aromatic chemicals from coal is till now coal tar with an availability of 22 Mio. t/a. The manufacturing of coal tar is discussed as an example for making aromatic products from a complex feed stock that you get by the fixed bed gasification, coal liquefaction and coking. Also the special marketing strategy that is necessary to be competitive against products from the petroindustry. It can be expected, that coal gasification as a source for synthesis gas will become more and more important. Synthesis gas is the access to aliphatic hydrocarbons by Fischer Tropsch synthesis and to methanol, a chemical with a high synthetic potential. Also the new hydrothermal carbonization of biomass to synthetic coal is mentioned. (orig.)

    New technologies will be critical in addressing current global energy challenges such as energy security. More must be done, however, to push forward the development and deployment of the technologies we need today and will need in the future. Government leaders have repeatedly underlined the crucial role of industry and businesses in advancing energy technologies and the importance of strong collaboration among all stakeholders to accelerate technology advances. To attain these goals, increased co-operation between industries, businesses and government energy technology research is indispensable. The public and private sectors must work together, share burdens and resources, while at the same time multiplying results and outcomes. The 42 multilateral technology initiatives (Implementing Agreements) supported by the IEA are a flexible and effective framework for IEA member and non-member countries, businesses, industries, international organisations and non-government organisations to research breakthrough technologies, to fill existing research gaps, to build pilot plants, to carry out deployment or demonstration programmes -- in short to encourage technology-related activities that support energy security, economic growth and environmental protection. This publication highlights the significant accomplishments of the IEA Implementing Agreements.

    Crystalline silicon (c-Si) solar cell, ever since its inception, has been identified as the only economically and environmentally sustainable renewable resource to replace fossil fuels. Performance c-Si based photovoltaic (PV) technology has been equal to the task. Its price has been reduced by a factor of 250 over last twenty years (from ˜ 76 USD to ˜ 0.3 USD); its market growth is expected to reach 100 GWP by 2020. Unfortunately, it is still 3-4 times higher than carbon-based fuels. With the matured PV manufacturing technology as it exists today, continuing price reduction poses stiff challenges. Alternate manufacturing approaches in combination with thin wafers, low (cost-based analysis of advanced solar cell manufacturing technologies aimed at higher (˜ 22 %) efficiency with existing equipment and processes.

    One of the least studied universal deformations of incompressible nonlinear elasticity, namely the straightening of a sector of a circular cylinder into a rectangular block, is revisited here and, in particular, issues of existence and stability are addressed. Particular attention is paid to the system of forces required to sustain the large static deformation, including by the application of end couples. The influence of geometric parameters and constitutive models on the appearance of wrinkles on the compressed face of the block is also studied. Different numerical methods for solving the incremental stability problem are compared and it is found that the impedance matrix method, based on the resolution of a matrix Riccati differential equation, is the more precise.

    We present a new, simple proof of existence for the Lanczos spinor potential in 3+1 dimensions that introduces a potential $T_{ABCD}= T_{(ABC)D}$ of the Lanczos potential together with several generalizations to other index configurations and metric signatures. The potential $T_{ABCD}$ can also be used to express, in a concise way, the gauge freedom left in the Lanczos potential after the differential gauge has been specified. We consider Einstein spacetimes and prove that in those spacetimes any symmetric (3,1)-spinor possesses a symmetric potential $H_{ABA'B'}$. Potentials of this type have earlier occurred in some special cases investigated e.g., by Torres del Castillo, Bergqvist and ourselves.

  3. Does the polystomatic gland exist?

    1989-03-01

    According to the P.N.A., the N.A.J. and some scholars, the sublingual gland has the ductus sublingualis major and ductus sublinguales minores. This means that the gland is a polystomatic gland. We intended to determine whether the so-called polystomatic gland exists or not. 1. According to the P.N.A., the N.A.J. and some scholars, the gl. sublingualis has the ductus sublingualis major and ductus sublinguales minores. This means the gland is a polystomatic gland. However, the formation of one gland with plural excretory ducts is embryologically impossible, in other words, the polystomatic gland does not exist. 2. Many scholars described that the gl. sublingualis was composed of the gl. sublingualis major and g11. sublinguales minores. However, they are completely different kinds of glands. Accordingly, we suggest the terms for these glands: the g1. sublingualis and its ductus sublingualis ("major" is useless), the g11. sublinguales minores and their ductus sublinguales minores. 3. The N.A.V.J. and some scholars use the term g1. sublingualis polystomatica or parvicanalaris. However, this is a group of a number of independent glands each of which has its own excretory duct. Such a gland should not be regarded as a single gland. We suggest that the term g11. sublinguales minores and their excretory ducts should be replaced with the term the ductus sublinguales minores. 4. The g1. lingualis anterior, g1. retromolaris and g1. lacrimalis are not single glands but a group of several independent glands each of which has its own excretory duct. Accordingly, they should be termed the g11. linguales anteriores, g11. retromolares and g11. lacrimales such as the g11. labiales, g11. buccales and g11. palatinae.

  6. Superheater Corrosion In Biomass Boilers: Today's Science and Technology

    Energy Technology Data Exchange (ETDEWEB)

    Sharp, William (Sandy) [SharpConsultant

    2011-12-01

    This report broadens a previous review of published literature on corrosion of recovery boiler superheater tube materials to consider the performance of candidate materials at temperatures near the deposit melting temperature in advanced boilers firing coal, wood-based fuels, and waste materials as well as in gas turbine environments. Discussions of corrosion mechanisms focus on the reactions in fly ash deposits and combustion gases that can give corrosive materials access to the surface of a superheater tube. Setting the steam temperature of a biomass boiler is a compromise between wasting fuel energy, risking pluggage that will shut the unit down, and creating conditions that will cause rapid corrosion on the superheater tubes and replacement expenses. The most important corrosive species in biomass superheater corrosion are chlorine compounds and the most corrosion resistant alloys are typically FeCrNi alloys containing 20-28% Cr. Although most of these materials contain many other additional additions, there is no coherent theory of the alloying required to resist the combination of high temperature salt deposits and flue gases that are found in biomass boiler superheaters that may cause degradation of superheater tubes. After depletion of chromium by chromate formation or chromic acid volatilization exceeds a critical amount, the protective scale gives way to a thick layer of Fe{sub 2}O{sub 3} over an unprotective (FeCrNi){sub 3}O{sub 4} spinel. This oxide is not protective and can be penetrated by chlorine species that cause further acceleration of the corrosion rate by a mechanism called active oxidation. Active oxidation, cited as the cause of most biomass superheater corrosion under chloride ash deposits, does not occur in the absence of these alkali salts when the chloride is present as HCl gas. Although a deposit is more corrosive at temperatures where it is molten than at temperatures where it is frozen, increasing superheater tube temperatures through the measured first melting point of fly ash deposits does not necessarily produce a step increase in corrosion rate. Corrosion rate typically accelerates at temperatures below the first melting temperature and mixed deposits may have a broad melting temperature range. Although the environment at a superheater tube surface is initially that of the ash deposits, this chemistry typically changes as the deposits mature. The corrosion rate is controlled by the environment and temperature at the tube surface, which can only be measured indirectly. Some results are counter-intuitive. Two boiler manufacturers and a consortium have developed models to predict fouling and corrosion in biomass boilers in order to specify tube materials for particular operating conditions. It would be very useful to compare the predictions of these models regarding corrosion rates and recommended alloys in the boiler environments where field tests will be performed in the current program. Manufacturers of biomass boilers have concluded that it is more cost-effective to restrict steam temperatures, to co-fire biofuels with high sulfur fuels and/or to use fuel additives rather than try to increase fuel efficiency by operating with superheater tube temperatures above melting temperature of fly ash deposits. Similar strategies have been developed for coal fired and waste-fired boilers. Additives are primarily used to replace alkali metal chloride deposits with higher melting temperature and less corrosive alkali metal sulfate or alkali aluminum silicate deposits. Design modifications that have been shown to control superheater corrosion include adding a radiant pass (empty chamber) between the furnace and the superheater, installing cool tubes immediately upstream of the superheater to trap high chloride deposits, designing superheater banks for quick replacement, using an external superheater that burns a less corrosive biomass fuel, moving circulating fluidized bed (CFB) superheaters from the convective pass into the hot recirculated fluidizing medium and adding an insulating layer to superheater tubes to raise their surface temperature above the dew point temperature of alkali chlorides. These design changes offer advantages but introduce other challenges. For example, operating with superheater temperatures above the dew point of alkali chlorides could require the use of creep-resistant tube alloys and doesn't eliminate chloride corrosion. Improved test methods that can be applied within this project include automated dimensional metrology to make a statistical analysis of depth of penetration and corrosion product thickness, and simultaneous thermal analysis measurements to quantify the melting of complex ashes and avoid the unreliability of the standard ash fusion test. Other important developments in testing include the installation of individually-temperature-controlled superheater loops for corrosion testing in operating boilers and temperature gradient testing.

    2011-12-01

    This report broadens a previous review of published literature on corrosion of recovery boiler superheater tube materials to consider the performance of candidate materials at temperatures near the deposit melting temperature in advanced boilers firing coal, wood-based fuels, and waste materials as well as in gas turbine environments. Discussions of corrosion mechanisms focus on the reactions in fly ash deposits and combustion gases that can give corrosive materials access to the surface of a superheater tube. Setting the steam temperature of a biomass boiler is a compromise between wasting fuel energy, risking pluggage that will shut the unit down, and creating conditions that will cause rapid corrosion on the superheater tubes and replacement expenses. The most important corrosive species in biomass superheater corrosion are chlorine compounds and the most corrosion resistant alloys are typically FeCrNi alloys containing 20-28% Cr.

    2006-05-01

    There has been considerable debate over the past three decades concerning the specific cause of the loss of the ship the Edmund Fitzgerald on Lake Superior on 10 November 1975, but there is little question that weather played a role in the disaster. There were only a few surface observations available during the height of the storm, so it is difficult to assess the true severity and meteorological rarity of the event. In order to identify likely weather conditions that occurred during the storm of 9-10 November 1975, high-resolution numerical simulations were conducted in an attempt to assess wind and wave conditions throughout the storm. Comparisons are made between output from the model simulations and available observational data from the event to assess the accuracy of the simulations. Given a favorable comparison, more detailed output from the simulations is presented, with a focus on high-resolution output over Lake Superior between 1800 UTC 9 November 1975 and 0600 UTC 11 November 1975. A detailed analysis of low-level sustained wind and significant wave height output is presented, illustrating the severity of the conditions and speed with which they developed and later subsided during the event. The high temporal and spatial resolution of the model output helps provide a more detailed depiction of conditions on Lake Superior than has previously been available.

    Full Text Available Specific chemotherapy against schistosomiasis together with environmental changes occurring in endemic areas of Brazil are causing a revolution in the clinico-pathological presentation of the disease when comparing to date from 10 to 15 years ago. To update the subject, an inquire was made among the most experienced Brazilian investigators in this field. They agree that a decrease of about 50 to 70% in prevalence, and an even higher decrease in incidence are taking place in Brazil today. The prevalence of schistosome-infection has decreased in some areas and increased in other, with spreading sometimes occurring to peri-urban regions, indicating that schistosomiasis control depends on the application of multiple measures. General clinical and pathological manifestations related to hepatosplenic disease, such as ascites, gastric hemorrhages, big-spleen syndrome, cor pulmonale, glomerulopathy, etc. are also less severe nowadays than they used to be in the past

    Full Text Available Christian theologians give many different interpretations to the Scriptures, particularly with regard to their ethical perspectives and their application to the present. An examination and criticism of various approaches adopted at present to the ethical dimension of the Scriptures is undertaken. A distinction is made between the revealed and lasting message of the Scriptitres and the message that is conditioned by culture and hence subject to change. Using the thought of Ricoeur and Hauerwas an approach is presented which attempts to do justice to the twofold polarity of the worid of the Bible and the world of today. In order to preserve a scenario of concreteness, attention is given to one practical example, namely the issue of homosexuality. After investigating the Scriptural approach to this question, an attempt is made to see how this issue can be viewed from a Christian perspective in the context of the present world.

  19. Spectroscopic Analysis of Today's Compact Fluorescent Light Bulbs

    2012-03-01

    In today's consumer market, there are many different light bulbs that claim to produce `natural' light. In my research, I both quantitatively and qualitatively analyzed this claim. First, utilizing a spectroscope, I compared the spectra emitted by different brands and types of compact fluorescent light (CFL) bulbs to the spectra emitted by the Sun. Once the bulbs were quantitatively analyzed, I proceeded to qualitatively analyze them by exposing subjects to the different bulbs. The subjects were asked to rate the quality of color in different pictures illuminated by each type of CFL. From these tests, I was able to determine the ``best'' CFL bulbs, and conclude whether the health risks associated with CFL bulbs outweigh the cost savings, longevity of the bulbs, and/or quality of light benefits.

  20. Crosscheck Principle in Pediatric Audiology Today: A 40-Year Perspective

    Science.gov (United States)

    2016-01-01

    The crosscheck principle is just as important in pediatric audiology as it was when first described 40 years ago. That is, no auditory test result should be accepted and used in the diagnosis of hearing loss until it is confirmed or crosschecked by one or more independent measures. Exclusive reliance on only one or two tests, even objective auditory measures, may result in a auditory diagnosis that is not clear or perhaps incorrect. On the other hand, close and careful analysis of findings for a test battery consisting of objective procedures and behavioral tests whenever feasible usually leads to prompt and accurate diagnosis of auditory dysfunction. This paper provides a concise review of the crosscheck principle from its introduction to its clinical application today. The review concludes with a description of a modern test battery for pediatric hearing assessment that supplements traditional behavioral tests with a variety of independent objective procedures including aural immittance measures, otoacoustic emissions, and auditory evoked responses.

  1. Biomarkers and childhood asthma: improving control today and tomorrow.

    2005-01-01

    Although we aim to normalize the lives of children with asthma by controlling their day and night symptoms and preventing exacerbations and morbidity, optimal childhood asthma management may result when the assessment and monitoring of asthma includes measured biomarkers--meaning objective, biological measures of lung dysfunction and inflammation. Precedence for such an approach to optimizing disease control and outcomes can be appreciated in comparing asthma with insulin-dependent diabetes mellitus (IDDM) management in children. Optimal management of these chronic conditions shares the fundamental goals to eliminate day and night symptoms and prevent exacerbations and morbidity. However, IDDM management focuses primarily on peripheral blood biomarkers of tight control (i.e., daily serum glucose levels) and predictors of long-term morbidity (i.e., hemoglobin A1C, or hemoglobin "remodeling" due to chronically poor control of glucose) for optimal assessment and monitoring and to best achieve these clinical objectives (Alemzadeh R, et al. Diabetes mellitus in children. In Nelson Textbook of Pediatrics, 17th ed. Behrman RE, Kliegman RM, and Jenson HB (Eds). Philadelphia: W.B. Saunders Co., 1947-1972, 2004). The improved outcomes in IDDM have resulted primarily from the progress to a biomarker-based assessment to achieve tight, optimal control and not, presently, as a dramatic change in therapy. The progress in IDDM management provides a compelling paradigm to consider for improving childhood asthma management. Indeed, the time is good to not only consider some newly available biomarkers, but also to reconsider some biomarkers of lung dysfunction, inflammation, and atopy that could be broadly used today. This article reconsiders the use of current and emerging measures of lung dysfunction, inflammation, and atopy in assessing tight control and long-term risk. Concluding emphasis will be placed on what can be implemented today.

    share crucial investigative information across jurisdictional bounds by establishing a communications infrastructure for all of its law enforcement jurisdictions. The Criminal Justice Network (CJ-Net) is a statewide TCP/IP network, dedicated to the sharing of law enforcement information. CJ-Net is managed and maintained by the Florida Department of Law Enforcement (FDLE) and provides open access and privileges to any criminal justice agency, including the state court and penitentiary systems. In addition to Florida, other states, such as North Carolina, are also beginning to implement common protocol communication infrastructures and architectures in order to link local jurisdictions together throughout the state. The law enforcement domain in an optimum situation for information-sharing technologies. Communication infrastructures are continually established, and as such, action is required to effectively use these networks to their full potential. Information technologies that are best suited for the law enforcement domain, must be evaluated and implemented in a cost-effective manner. Unlike the Defense Department and other large federal agencies, individual jurisdictions at both the local and state level cannot afford to expend limited resources on research and development of prototype systems. Therefore, we must identify enabling technologies that have matured in related domains and transition them into law enforcement at a minimum cost. Crucial to this measure, is the selection of the appropriate levels of information-sharing technologies to be inserted. Information-sharing technologies that are unproven or have extensive recurring costs are not suitable for this domain. Information-sharing technologies traditionally exist between two distinct polar bounds: the data warehousing approach and mediation across distributed heterogeneous data sources. These two ends of the spectrum represent extremely different philosophies in accomplishing the same goal. In the

    2016-01-01

    The relationship between obesity and other metabolic diseases have been deeply studied. However, there are clinical inconsistencies, exceptions to the paradigm of “more fat means more metabolic disease”, and the subjects in this condition are referred to as metabolically healthy obese (MHO).They have long-standing obesity and morbid obesity but can be considered healthy despite their high degree of obesity. We describe the variable definitions of MHO, the underlying mechanisms that can explain the existence of this phenotype caused by greater adipose tissue inflammation or the different capacity for adipose tissue expansion and functionality apart from other unknown mechanisms. We analyze whether these subjects improve after an intervention (traditional lifestyle recommendations or bariatric surgery) or if they stay healthy as the years pass. MHO is common among the obese population and constitutes a unique subset of characteristics that reduce metabolic and cardiovascular risk factors despite the presence of excessive fat mass. The protective factors that grant a healthier profile to individuals with MHO are being elucidated. PMID:27258304

    The contribution discusses the means available to administrative law in coping with scientific and technological developments. The potentials and chances of technology are reviewed in contrast to the immanent risks, and technology and law are discussed in their interactive relations. The role of the law is explained with regard to supervisory and controlling functions, referring to practical examples (licensing of installations, biological and genetic engineering, information and communication science and technology). The author discusses the efficiency of control (preventive prohibition subject to possible licensing, averting danger, preventing risks, strict liability regimes, planning laws), as well as the time problem (protection of existing rights, stepwise licensing procedures, subsequent instructions and supervision), and judical review. Finally, the author discusses the ways technology may win (improvement of acceptance procedures, judicial control) and the rather unsatisfactory conditions today. (RST).

    1988-01-01

    The safety of blood and blood products in Scandinavia today is high. An absolutely safe blood supply is, however, an unattainable goal. The dominating risk is transmission of non-A, non-B virus (NANBV). The calculated per blood unit risk is 1:200. The incidence of cirrhosis due to post-transfusion hepatitis NANB is calculated to at most 0.1% among recipients of blood components from about 5 donors. Other risk factors are transmission of hepatitis B virus (HBV), human immunodeficiency virus (HIV-1) and cytomegalovirus (CMV). The prevalence of HBsAg among first time donors is about 0.05% (Sweden). In Scandinavia, anti-HIV-1 has been found in 0.001% of donations from start of screening in 1985 to December 1987. The prevalence was higher in Denmark, lower in Finland (and perhaps Iceland). The prevalence has declined during the last years. As of June 1988, 117 patients in the Scandinavian countries have been infected by blood components, all but 2 before screening was introduced. Besides these, 226 haemophiliacs have been infected by, in almost all cases, imported clotting factor concentrates before heat treatment was introduced. Most of the infected patients are still asymptomatic. About 70% of blood donors have anti-CMV, a few percent of which will transmit CMV-infection, with severe symptoms, to immunosuppressed patients without anti-CMV.

    Full Text Available This paper aims to contribute to a constructive debate on human rights. The two World Wars of the last century brought about the creation of the United Nations aimed “to reaffirm faith in fundamental human rights, in the dignity and worth of the human person, in the equal rights of men and women and of nations large and small”. Only three years later the Universal Declaration of the Human Rights was elaborated and promoted by the UN, considered to be the foundation of international human rights law. Today, as globalization brings all closer together in a “global village”, one can see that there are many ways to perceive and guarantee human rights, in different states, but also within different states. Poverty, illiteracy, censorship, cruel treatment and even the lack of guarantee for the right to life are, unfortunately, the norm for many people of the world. Such observations bring up questions regarding the legitimacy, universality and coherence of human rights.

  10. Variation under domestication in plants: 1859 and today.

    Brown, Anthony H D

    2010-08-27

    Charles Darwin began The Origin of Species with a chapter entitled variation under domestication, which encapsulated decades of his research on a diverse array of animal and plant domesticated species. Variation in these species compared with that in their wild relatives, their origins and their selection by humans, formed a paradigm for his theory of the evolutionary origin of species by means of natural selection. This chapter, its subsequent expansion into a two-volume monograph, together with the rediscovery of Mendel's laws, later became the foundation of scientific plant breeding. In the period up to the present, several advances in genetics (such as artificial mutation, polyploidy, adaptation and genetic markers) have amplified the discipline with concepts and questions, the seeds of which are in Darwin's original words. Today, we are witnessing a flowering of genomic research into the process of domestication itself, particularly the specific major and minor genes involved. In one striking way, our view of domestic diversity contrasts with that in Darwin's writing. He stressed the abundance of diversity and the diversifying power of artificial selection, whereas we are concerned about dwindling genetic diversity that attends modern agriculture and development. In this context, it is paramount to strive for a deeper understanding of how farmer selection including both deliberate selection and unconscious selection, might generate and retain diversity. This knowledge is essential for devising in situ conservation measures.

  11. The power of data: structural bioinformatics yesterday and today

    KAUST Repository

    Tramontano, Anna

    2016-01-25

    The protein structure database was established in 1971. At the time it contained seven structures, today there are more than 100,000. The improvement is not only a matter of quantity, but also of quality. Did we effectively exploit this information to gain knowledge? The answer is certainly affirmative. I will illustrate how this wealth of experimental data has allowed us to explore the landscape of macromolecular structures on one side, and to uncover the properties of specific protein families on the other. The latter plays an essential role in pursuing exciting new avenues in biomedical and biotechnological sciences. Experimental data are also part of a virtuous cycle whereby they reinforce and guide our ability to infer unknown macromolecular structures, which, while providing relevant information to scientists, permits to gauge the level of our understanding of the complex problem of protein folding. A paradigmatic example of the latter is represented by the “Critical Assessment of Techniques for Protein Structure Prediction” (CASP) initiative that I will briefly discuss.

    Full Text Available The paper deals with the problem of the theoretical exploration of maternity and motherhood as a feminist political idea and includes the overview of the social practices and methods aimed at strengthening maternity and parenting in modern states, emphasizing the issue of the political support and social status of motherhood in Serbia today. The general trend in current changes is the separation of the population policy from the social policy of family planning, and deterioration of the social status of parenthood and motherhood, while the formal legal framework and ideas for improving the gender equality has been nominally improved, which contributes to their impracticability. Recent changes and adoption of new laws dealing with family and parenthood are fully adapted to the neoliberal transformation of Serbia, within which the social position of women is getting worse. In response, nationalist and patriarchal family policy are reinforced in the broader society. The article highlights the importance of examining women’s experiences and needs of women related to their reproduction and maternity, as a necessary starting point for developing appropriate policies in the wider society.

This review gathers updated recommendations considering the lifestyle, dietary, sociocultural, environmental and health challenges that the current Mediterranean populations are facing. Mediterranean region and its populations. Many innovations have arisen since previous graphical representations of the MD. First, the concept of composition of the 'main meals' is introduced to reinforce the plant-based core of the dietary pattern. Second, frugality and moderation is emphasised because of the major public health challenge of obesity. Third, qualitative cultural and lifestyle elements are taken into account, such as conviviality, culinary activities, physical activity and adequate rest, along with proportion and frequency recommendations of food consumption. These innovations are made without omitting other items associated with the production, selection, processing and consumption of foods, such as seasonality, biodiversity, and traditional, local and eco-friendly products. Adopting a healthy lifestyle and preserving cultural elements should be considered in order to acquire all the benefits from the MD and preserve this cultural heritage. Considering the acknowledgment of the MD as an Intangible Cultural Heritage of Humanity by UNESCO (2010), and taking into account its contribution to health and general well-being, we hope to contribute to a much better adherence to this healthy dietary pattern and its way of life with this new graphic representation.

Pocket money is one of the first ways for children to learn the basics of managing money – a skill they’ll definitely need for life – and it makes children feel independent. Whether to give pocket money, and at what age, and how much to give are issues that often concern parents. There are many ways to handle this. To a large extent it depends on family values, practices and finances. The main reason for giving children pocket money is to help children learn to be able to manage money while they are still young and parents can guide them. It also may help children to feel that they are important members of the family, because they are given part of the family's spending money.

  15. Karl Marx and the Study of Media and Culture Today

    Directory of Open Access Journals (Sweden)

    Christian Fuchs

    2014-02-01

    Full Text Available The task of this paper discusses the role of Marx in analysing media, communica-tion and culture today. An analysis of three contemporary Cultural Studies works – Lawrence Grossberg’s monograph Cultural Studies in the Future Tense, John Hartley’s monograph Digital Futures for Cultural and Media Studies and Paul Smith’s edited volume The Renewal of Cultural Studies – shows that there is an agreement that the economy needs to be taken more into account by Cultural Studies, but disagreement on which approach should be taken and what the role of Karl Marx’s works shall be. The paper argues that Marx’s labour theory of value is especially important for critically analysing the media, culture and communica-tion. Labour is still a blind spot of the study of culture and the media, although this situation is slowly improving. It is maintained that the turn away from Marx in Cultural and Media Studies was a profound mistake that should be reverted. Only an engagement with Marx can make Cultural and Media Studies topical, politically relevant, practical and critical, in the current times of global crisis and resurgent critique.

  16. The analytic setting today: using the couch or the chair?

    Science.gov (United States)

    Wiener, Jan

    2015-09-01

    This paper re-visits Murray Jackson's 1961 paper in the Journal of Analytical Psychology, 'Chair, couch and countertransference', with the aim of exploring the role of the couch for Jungian analysts in clinical practice today. Within the Society of Analytical Psychology (SAP) and some other London-based societies, there has been an evolution of practice from face-to-face sessions with the patient in the chair, as was Jung's preference, to a mode of practice where patients use the couch with the analyst sitting to the side rather than behind, as has been the tradition in psychoanalysis. Fordham was the founding member of the SAP and it was because of his liaison with psychoanalysis and psychoanalysts that this cultural shift came about. Using clinical examples, the author explores the couch/chair question in terms of her own practice and the internal setting as a structure in her mind. With reference to Bleger's (2013) paper 'Psychoanalysis of the psychoanalytic setting', the author discusses how the analytic setting, including use of the couch or the chair, can act as a silent container for the most primitive aspects of the patient's psyche which will only emerge in analysis when the setting changes or is breached.

  17. Interfaith education: A new model for today's interfaith families

    Science.gov (United States)

    Gordon, Sheila C.; Arenstein, Benjamin

    2017-04-01

    With societal changes rapidly transforming cultures that had been largely homogenous, today's multi-cultural - and in particular interfaith - families need new educational strategies to help them understand their cultural roots and identify and clarify what aspects of their heritages they wish to nurture and transmit to their children. This paper focuses on a new model for religious education, namely non-doctrinaire "dual-faith" education, which the principal author has helped to develop in the United States (US) through the Interfaith Community (IFC), a small, independent non-profit organisation created and led by dual-faith Jewish/Christian families. The model is premised on the notion that families can have two different faiths in one household and that - with respect and education - families can be harmonious, religion can be transmitted, and tolerance broadly nurtured. While the model is particular to the US and to families with Jewish and Christian heritages, its premises and structure have significant potential to be adaptable to other religious combinations and other cultures and countries. After reviewing relevant literature and situating the IFC model in the global and US contexts, the paper sets out to clarify the importance of the concept, describe its elements, and discuss its implications for religious education in this time of changing ethos and demography.

    This report summarizes the core research, development, and technology accomplishments in Lawrence Livermore National Laboratory's Engineering Directorate for FY2006. These efforts exemplify Engineering's more than 50-year history of developing and applying the technologies needed to support the Laboratory's national security missions. A partner in every major program and project at the Laboratory throughout its existence, Engineering has prepared for this role with a skilled workforce and technical resources developed through both internal and external venues. These accomplishments embody Engineering's mission: ''Enable program success today and ensure the Laboratory's vitality tomorrow''. Engineering's investment in technologies is carried out primarily through two internal programs: the Laboratory Directed Research and Development (LDRD) program and the technology base, or ''Tech Base'', program. LDRD is the vehicle for creating technologies and competencies that are cutting-edge, or require discovery-class research to be fully understood. Tech Base is used to prepare those technologies to be more broadly applicable to a variety of Laboratory needs. The term commonly used for Tech Base projects is ''reduction to practice''. Thus, LDRD reports have a strong research emphasis, while Tech Base reports document discipline-oriented, core competency activities. This report combines the LDRD and Tech Base summaries into one volume, organized into six thematic technical areas: Engineering Modeling and Simulation; Measurement Technologies; Micro/Nano-Devices and Structures; Precision Engineering; Engineering Systems for Knowledge and Inference; and Energy Manipulation.

    and user. This philosophy is reflected in the recommendations given with respect to research and development priorities. Key issues within Gas Transport and Processing are optimised operations, capacity utilization and cost effectiveness in existing infrastructure through e.g. improved methods for maintenance, energy efficiency programs, handling of trace components in gas streams (H2S, CO2, Methanol) and more efficient extraction of heavy components (NGL, LPG). Furthermore, we need to develop a robust technology basis for non-pipeline transportation of gas from regions that are not accessible today by pipeline infrastructure. This includes Liquefied Natural Gas (LNG), Compressed Natural Gas (CNG), Heavy Liquefied Gas (HLG), Natural Gas Hydrates (NGH) for transport, and the like. The versatility of these technologies for new regions (e.g. Arctic and remote areas) needs to be researched and improved. For Gas conversion to fuels, chemicals and materials it is expected that the existing Norwegian gas based industry, incl. petrochemicals, will be developed further and key issues in this regard are increased unit capacities and increased energy efficiency. It is also expected that this industry will expand further internationally. Pacing technologies within gas conversion are Gas to Liquids (GTL) and Gas to Olefins (GTO) with Norwegian companies as leading players technologically and commercially. It is a possibility that in countries with strong national petroleum companies, participation in downstream business development will strengthen the position for access to upstream assets. GTL and GTO are good examples of this. Other pacing and emerging areas are offshore gas conversion to transportable liquids as well as new direct conversion routes to products, hydrogen as energy carrier and gas conversion in Arctic areas. New products where gas is feed stock are likely to occur in the future, one example is nano materials. CO{sub 2} management encompasses improved energy

In this paper, several software engineering technologies used within NASA are studied, and the mechanisms, schedules, and efforts at transferring these technologies are investigated. The goals of this study are: 1) to understand the difference between technology transfer (the adoption of a new method by large segments of an industry) as an industry-wide phenomenon and the adoption of a new technology by an individual organization (called technology infusion); and 2) to see if software engineering technology transfer differs from other engineering disciplines. While there is great interest today in developing technology transfer models for industry, it is the technology infusion process that actually causes changes in the current state of the practice.

    2006-01-01

    In recent years, sales leaders have had to devote considerable time and energy to establishing and maintaining disciplined processes. The thing is, many of them stop there--and they can't afford to, because the business environment has changed. Customers have gained power and gone global, channels have proliferated, more product companies are selling services, and many suppliers have begun providing a single point of contact for customers. Such changes require today's sales leaders to fill various new roles: Company leader. The best sales chiefs actively help formulate and execute company strategy, and they collaborate with all functions of the business to deliver value to customers. Customer champion. Customers want C-level relationships with suppliers in order to understand product strategy, look at offerings in advance, and participate in decisions made about future products--and sales leaders are in the best position to offer that kind of contact. Process guru. Although sales chiefs must look beyond the sales and customer processes they have honed over the past decade, they can't abandon them. The focus on process has become only more important as many organizations have begun bundling products and services to meet important customers' individual needs. Organization architect. Good sales leaders spend a lot of time evaluating and occasionally redesigning the sales organization's structure to ensure that it supports corporate strategy. Often, this involves finding the right balance between specialized and generalized sales roles. Course corrector. Sales leaders must watch the horizon, but they can't take their hands off the levers or forget about the dials. If they do, they might fail to respond when quick adjustments in priorities are needed.

    Full Text Available Since its birth in the mid-1980s, as a major variant of critical criminology, Left Realism continues to ebb and flow. Furthermore, not all Left realist contributions are alike and some are subject to very heated debates. The fact remains, however, that Left Realism is ‘alive and well’. Of course, given that I devoted 26 years of my life (much of it with Martin D Schwartz to the realist project, I could easily be accused of being biased. Nonetheless, some contemporary empirical support for my claim is the recent publication of Roger Matthews’ (2014 book Realist Criminology. The main objective of this volume is to use this offering as a ‘launching pad’ or ‘springboard’ for broader analyses of the relevance of Left Realism to critical criminology as we know it today. Matthews’ piece is the lead article. Following this are six others that, in part, address his monograph and that also point us to new directions in Left realist ways of knowing. In keeping with the spirit of the International Journal of Crime, Justice and Social Democracy, the authors constitute an international cadre of progressive scholars, including me, Joseph Donnermeyer, Steve Hall, Russell Hogg, John Lea, Claire Renzetti, and Simon Winlow. It cannot be emphasized enough, though, that this special issue is not a ‘love-in’ and there is no ‘party line’ here. All of the authors have strong positions on topics of major concern to academics and activists seeking new ways of thinking critically about crime, law and social control.

    2008-05-01

    In today's digital, on-demand society, consumers of information both want to know exactly what is happening as it is happening, and to be able to subscribe to content of their choosing. Meeting the needs of these tech savvy individuals are bloggers, podcasters and vodcasters. Using text, audio, and video to reach their respective audiences, these communicators are the new face of public outreach and journalism, but even their communications means are starting to become passé in the face of live blogging. The idea behind live blogging is simple: Take any person - even an undergraduate - with an Internet connected device, put them someplace interesting, and have them report on what they are seeing and experiencing online in real-time. This new tool is bringing astronomy enthusiasts around the world the thrill of live astronomy announcements, attending talks in real, and being "in the room" with astronomers via an Internet connection. These audiences can be anyone, from any nation, with any age. Beyond the public communications benefits of this program, it is also a program that allows the participation of early undergraduate students in science conferences. To date, two undergraduate students and five E/PO professionals have live blogged text, audio, and video content from three science conferences and a shuttle launch. Together, they have produced over 200 hundred stories that have reached tens of thousands of people around the world. In this poster we describe how we have made astronomy live blogging a reality from both the technical and personal standpoint. This project is funded through NSF grant # 0744944.

    In order to handle more efficiently projects of restoration, documentation and maintenance of historical buildings, it is essential to rely on a 3D enriched model for the building. Today, the concept of Building Information Modelling (BIM) is widely adopted for the semantization of digital mockups and few research focused on the value of this concept in the field of cultural heritage. In addition historical buildings are already built, so it is necessary to develop a performing approach, based on a first step of building survey, to develop a semantically enriched digital model. For these reasons, this paper focuses on this chain starting with a point cloud and leading to the well-structured final BIM; and proposes an analysis and a survey of existing approaches on the topics of: acquisition, segmentation and BIM creation. It also, presents a critical analysis on the application of this chain in the field of cultural heritage.

    1982-12-24

    After more than 25 years of development of nuclear power and almost 10 years of research and development in numerous areas of nonnuclear energy, there is now a good basis for judging the future prospects of energy technologies in the Federal Republic of Germany. The development of nuclear power has provided an important and economically advantageous new source of energy. Further efforts are needed to establish the nuclear fuel cycle in all stages and to exploit the potential of advanced reactors. In all other areas of energy technology, including energy conservation, new energy sources, and coal, economics has turned out to be the key problem, even at today's energy prices. Opportunities to overcome these economic problems through additional R & D are limited. There is some potential for special applications, and there are many technologies that could contribute to the energy supply of developing countries. In general, however, progress in energy conservation and the use of renewable energy sources will depend on the degree to which energy policy measures can improve their economic basis. For some technologies, such as solar thermal power stations and coal liquefaction, large-scale economic deployment cannot be foreseen today. Instead of establishing costly demonstration projects, emphasis will be put on improving key components of these technologies with the aim of having the most advanced technology available when the economic parameters are more favorable.

    Clinical microbiology is clearly on the move, and various new diagnostic technologies have been introduced into laboratory practice over the past few decades. However, Henri D Isenberg recently stated that molecular biology techniques promised to revolutionise the diagnosis of infectious disease, but that, to date, this promise is still in its infancy. Molecular diagnostics have now surpassed these early stages and have definitely reached puberty. Currently, a second generation of automated molecular approaches is already within the microbiologists' reach. Quantitative amplification tests in combination with genomics, transcriptomics, proteomics and related methodologies will pave the way to further enhancement of innovative microbial detection and identification.

    2010-12-01

    This paper deliberates on one of the all-time issues in philosophy, theology, (bio)ethics and medicine, that is, the issue of death and dying, placing it in a contemporary context. Namely, contemporary medicine with its expanding knowledge in the field of biomedical science and technology, requires a new approach in determination of its goals. Nowadays, more than ever, these goals need a revision from an interdisciplinary point of view. Exactly in the context of those goals, the issue of death and dying should be approached, taking into account four entities known in clinical bioethics, i.e. the bioethical classification of death and dying: euthanasia, mysthanasia, dysthanasia and orthothanasia.

    Interest in family studies is usually concomitant with new developments in social, economic, and ideological spheres of a society. The family in premodern times was characterized by a home-centered, fundamentally agrarian mode of production. The family was the basic unit in the whole economy. To the individual family member it was multifunctional, representing the source of occupational skills, basic education, employment, nutrition, and a sense of security. Historical demographers have found that: 1) there was a wide variety of communal living in preindustrial times, 2) the number of children did not exceed 4 on the average, and 3) the agrarian household showed considerable occupational mobility. Industrialization lessened the importance of land ownership and increased that of capital and of educational level, diluting the role of the father and intruding liberalism into family life by emphasizing individualistic goals. The conviction that only a small family may sufficiently enjoy the pleasures of an affluent society brought into existence the nuclear family as the predominant pattern, consisting only of the married couple and their immature offspring. A gap exists between family norms and family life as it exists, especially as regards premarital sex, women's roles, and divorce. Alternatives to traditional family life now exist such as: 1) the single state, 2) cohabitation, 3) divorce, and 4) desertion. The low fertility syndrome in advanced societies expresses a change in attitude, induced by reorganization of productive forces, labor conditions, and improved social security. Shrinking family size means an increase in childlessness, a cluster around 1st and 2nd births, and a gradual vanishing of 4th or even 3rd order births and more. Liberalization of abortion laws has forced social researchers to develop research methods to ascertain the numbers of legal as well as illegal abortions; in one survey it was found that most decisions to obtain an abortion occur

    The tunnel section of Xiaoshenzi station and tunnel of Chongqing subway line 1 change frequently. The buried depth of part of the tunnel is shallow. Moreover, there is a existing air defense tunnel paralleled to the subway tunnel. Based on the situation, the full section excavation method of a short-drilling footage, dim blasting and layered split station, construction method with annular damping hole and static breaking excavation method are used in the tunnel construction. Ultimately, safety of the tunnel excavation and its surrounding buildings are ensured. The result shows that these construction technologies have a good effect on the tunnel excavation.%重庆市轨道交通1号线小什字车站及区间隧道工程断面变化频繁,部分隧道埋深浅,且存在1条与拟建地铁区间隧道走向基本一致的既有人防隧道.针对现场实际情况,分别采用短进尺、弱爆破、分层剥离车站全断面开挖方法、环形减振孔爆破开挖方法、静态破碎开挖方法,最终确保了隧道洞身开挖施工的安全和周围地上建筑物的安全,并取得较好效果.

    A growing body of literature suggests that today's learners have changed and education must change as well since Millennial generation students expect technology to be used in their coursework. This study sought to determine what educational technology is being used in U.S. dental hygiene programs, what student and faculty perceptions are of the effectiveness of technology, and what barriers exist to implementing educational technology. A stratified random sample of 120 entry-level dental hygiene programs nationwide were invited to participate in a survey. Fourteen programs participated, yielding a pool of 415 potential individual participants; out of those, eighty-four student and thirty-eight faculty respondents were included in the analysis, a total of 122. Results were analyzed using descriptive statistics and a Mann-Whitney U test (p<0.05). Faculty and student respondents agreed on the effectiveness of educational technology in all areas except clickers and wikis. The faculty members tended to rate the effectiveness of educational technology higher than did the students. The greatest perceived barrier to implementing technology was technical difficulties. This study suggests that support services should be available to faculty and students to ensure successful implementation of technology. Dental hygiene educators have adopted many types of educational technology, but more data are needed to determine best practices.

    Today's society expects and demands immediate service, results and access to information. Can those of us in leadership positions say that the service we provide is equal to or exceeds what our customers expect? How can we redesign our services so they are better than those we currently provide? Some people look to advances in technology as one means to improve services and access to information, but this should not be the only means. If we are to develop a philosophy of exceptional service, we must develop a vision of those services. We must gain an understanding of our customers, plus a knowledge of products, the availability of resources and any industry constraints. In healthcare, we must look to leadership to achieve our goals. A goal of exceptional customer service must be communicated to all levels of service providers from management. Top-down action by management--leadership by example--is critical. Leadership must gain the trust of both customers and employees by actively listening to both verbal and nonverbal comments at all points of service. Without an understanding of our customers' needs, it won't be possible to deliver services at or above their expectations.

    Flexible and stretchable electronics can dramatically enhance the application of electronics for the emerging Internet of Everything applications where people, processes, data and devices will be integrated and connected, to augment quality of life. Using naturally flexible and stretchable polymeric substrates in combination with emerging organic and molecular materials, nanowires, nanoribbons, nanotubes, and 2D atomic crystal structured materials, significant progress has been made in the general area of such electronics. However, high volume manufacturing, reliability and performance per cost remain elusive goals for wide commercialization of these electronics. On the other hand, highly sophisticated but extremely reliable, batch-fabrication-capable and mature complementary metal oxide semiconductor (CMOS)-based technology has facilitated tremendous growth of today\\'s digital world using thin-film-based electronics; in particular, bulk monocrystalline silicon (100) which is used in most of the electronics existing today. However, one fundamental challenge is that state-of-the-art CMOS electronics are physically rigid and brittle. Therefore, in this work, how CMOS-technology-enabled flexible and stretchable electronics can be developed is discussed, with particular focus on bulk monocrystalline silicon (100). A comprehensive information base to realistically devise an integration strategy by rational design of materials, devices and processes for Internet of Everything electronics is offered. © 2015 WILEY-VCH Verlag GmbH & Co.
