    Fiber sensor technologies are overviewed. Since the early 1970s, this field has been developed, on the basis of the same devices and photonic principles as fiber communication technologies. Besides simple configurations, in which the fiber acts only as a data transmission line, sophisticated configurations have also been developed, in which the fiber is used as a device to realize unique sensing mechanisms. The fiber optic gyroscope (FOG) is a good example, and has been developed as an absolute rotation sensor used, for example, for navigation and/or attitude control applications. Compared with traditional spinning-mass gyroscopes, the FOG has advantages, such as a short warming-up time, a light weight, and easy handling. A Japanese satellite, which was launched in August 2005 with a mission to observe the aurora, is controlled with a FOG. The FOG has also been used in consumer applications, such as the camera stabilizer, radio-controlled (RC) helicopter navigation, and the control of humanoid robots. Recently, distributed and multiplexed sensing schemes, in particular, have been studied and developed, in which a long fiber acts like a “nerve” for feeling the strain and/or the temperature distribution along the fiber. Performances of artificial nerve systems have markedly improved within the last couple of years, in spatial resolution and measurement speed. By embedding the “fiber-optic nerve system” in aircraft wings, bridges and tall buildings, these materials and structures can sense damage to prevent disasters.

    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?

    The current state of the technology of nuclear weapons and the corresponding missile systems is presented. It will be shown, that the weapons systems have made particular progress since the sixites. These advances, particularly through the MIRV principle, have a destabilizing influence and threaten the existing balance of terror. A new military doctrine, after which it could be possible, through a concentrated, surprising attack, to destroy the military installations of the enemy and thereby forestall retaliation. Considering the excessive demands of the commanding authorities in case of a conflict the development heads for extreme automation. It is shown that the increasing automation causes a lack of safety. Furthermore, the outbreak of a nuclear war could erupt without human decision. A solution to the world’s security issue can not be found at a technical level, but only at the level of practical peace policy. (zarka) [de

    Extensive research has been conducted in the development of methods to predict the degradation of F-44 in storage. The Low Pressure Reactor (LPR) has greatly enhanced the stability prediction capabilities necessary to make informed decisions concerning aviation fuel in storage. This technique has in the past been primarily used for research purposes. The Naval Air Warfare Center, Aircraft Division, Trenton, NJ, has used this technique successfully to assist the Defense Fuel Supply Center, Cameron Station, Alexandria, VA, in stability assessments of F-44. The High Performance Liquid Chromatography/Electrochemical Detector (HPLC/EC) antioxidant determination technique has also aided in making stability predictions by establishing the amount of inhibitor currently in the product. This paper will address two case studies in which the above new technology was used to insure the rapid detection and diagnosis of today`s field and logistic problems.

    Human computer interaction (HCI) equates nurses using voice assisted technology within a clinical setting to document patient care real time, retrieve patient information from care plans, and complete routine tasks. This is a reality currently utilized by clinicians today in acute and long term care settings. Voice assisted documentation provides hands & eyes free accurate documentation while enabling effective communication and task management. The speech technology increases the accuracy of documentation, while interfacing directly into the electronic health record (EHR). Using technology consisting of a light weight headset and small fist size wireless computer, verbal responses to easy to follow cues are converted into a database systems allowing staff to obtain individualized care status reports on demand. To further assist staff in their daily process, this innovative technology allows staff to send and receive pages as needed. This paper will discuss how leading edge and award winning technology is being integrated within the United States. Collaborative efforts between clinicians and analyst will be discussed reflecting the interactive design and build functionality. Features such as the system's voice responses and directed cues will be shared and how easily data can be documented, viewed and retrieved. Outcome data will be presented on how the technology impacted organization's quality outcomes, financial reimbursement, and employee's level of satisfaction.

    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.

    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.

    2008-12-01

    Currently, autologous chondrocyte implantation and osteochondral grafting bridge the gap between palliation of cartilage injury and resurfacing via arthroplasty. Emerging technologies seek to advance first generation techniques and accomplish several goals including predictable outcomes, cost-effective technology, single-stage procedures, and creation of durable repair tissue. The biologic pipeline represents a variety of technologies including synthetics, scaffolds, cell therapy, and cell-infused matrices. Synthetic constructs, an alternative to biologic repair, resurface a focal chondral defect rather than the entire joint surface. Scaffolds are cell-free constructs designed as a biologic "net" to augment marrow stimulation techniques. Minced cartilage technology uses stabilized autologous or allogeneic fragments in 1-stage transplantation. Second and third generation cell-based methods include alternative membranes, chondrocyte seeding, and culturing onto scaffolds. Despite the promising early results of these products, significant technical obstacles remain along with unknown long-term durability. The vast array of developing technologies has exceptional promise and the potential to revolutionize the cartilage treatment algorithm within the next decade.

    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 growing popularity of the Internet is the key driver behind the development of new access methods which would enable a customer to experience a true broadband. Amongst various technologies, the access methods based on the optical fiber are getting more and more attention as they offer the ultimate solution in delivering different services to the customers' premises. Three different architectures have been proposed that facilitate the roll out of Fiber-to-the-Home (FTTH) infrastructure. Point-to-point Ethernet networks are the most straightforward and already matured solution. Different flavors of Passive Optical Networks (PONs) with Time Division Multiplexing Access (TDMA) are getting more widespread as necessary equipment is becoming available on the market. The third main contender are PONs withWavelength DivisionMultiplexing Access (WDMA). Although still in their infancy, the laboratory tests show that they have many advantages over present solutions. In this paper we show a brief comparison of these three access methods. In our analysis the architecture of each solution is presented. The applicability of each system is looked at from different viewpoint and their advantages and disadvantages are highlighted.

  3. Integrated testing strategies for toxicity employing new and existing technologies.

    Combes, Robert D; Balls, Michael

    2011-07-01

    We have developed individual, integrated testing strategies (ITS) for predicting the toxicity of general chemicals, cosmetics, pharmaceuticals, inhaled chemicals, and nanoparticles. These ITS are based on published schemes developed previously for the risk assessment of chemicals to fulfil the requirements of REACH, which have been updated to take account of the latest developments in advanced in chemico modelling and in vitro technologies. In addition, we propose an ITS for neurotoxicity, based on the same principles, for incorporation in the other ITS. The technologies are deployed in a step-wise manner, as a basis for decision-tree approaches, incorporating weight-of-evidence stages. This means that testing can be stopped at the point where a risk assessment and/or classification can be performed, with labelling in accordance with the requirements of the regulatory authority concerned, rather than following a checklist approach to hazard identification. In addition, the strategies are intelligent, in that they are based on the fundamental premise that there is no hazard in the absence of exposure - which is why pharmacokinetic modelling plays a key role in each ITS. The new technologies include the use of complex, three-dimensional human cell tissue culture systems with in vivo-like structural, physiological and biochemical features, as well as dosing conditions. In this way, problems of inter-species extrapolation and in vitro/in vivo extrapolation are minimised. This is reflected in the ITS placing more emphasis on the use of volunteers at the whole organism testing stage, rather than on existing animal testing, which is the current situation. 2011 FRAME.

    The blackout of August 14, 2003 is used as the incentive to examine transmission grid reliability, expose its deficiencies in terms of technology, standards and processes used to manage reliability, and to make recommendations for leveraging existing resources and upgrading both the technology and procedures to avoid similar breakdowns in the future. It is recommended that in the area of monitoring transmission grid reliability utilities should borrow a page from the Enterprise Risk Management Practices of the financial industry by adopting a system which looks beyond the first 'credible' contingency (the current system) and examine many more 'incredible' contingencies, and underlying events that can trigger multiple contingencies, and plan for them in their operations. Utility companies are also urged to upgrade their energy management systems (EMS) technology to be able to deal with the kinds of severely depressed voltages and overloaded circuits that many grids experience today. Investment in new capabilities in control rooms, more and better communications will be essential. EMS algorithms and models must be upgraded to operate under a broader spectrum of grid conditions and to simulate the once-in-a-lifetime outage scenarios that most operators believe could never strike their utility. Expert opinion strongly suggests that as part of this process of upgrading, contingency analysis should shift from the 'N-1' model of the present to a stochastic model that considers a wider range of possible events in a probabilistic framework

    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

    The application and operation of safeguards instrumentation in a facility containing special nuclear material is most successful when the installation is designed for the operation of the specific facility. Experience at the Idaho National Engineering Laboratory demonstrates that installation designs must consider both Safeguards and Production requirements of specific facilities. Equipment selection and installation design influenced by the training and experience of production operations and safeguards personnel at a specific facility help assure successful installation, reliable operation, and minimal operator training. This minimizes impacts on existing plant production activities while maximizing utility of the safeguards information obtained

    Full Text Available The article presents the results of an analytical review and comparison of the most common managerial decision support technologies: the analytic hierarchy method, neural networks, fuzzy set theory, genetic algorithms and neural-fuzzy modeling. 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.

  17. Integrating New Technologies and Existing Tools to Promote Programming Learning

    Full Text Available In recent years, many tools have been proposed to reduce programming learning difficulties felt by many students. Our group has contributed to this effort through the development of several tools, such as VIP, SICAS, OOP-Anim, SICAS-COL and H-SICAS. 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.

  18. Psychoanalysis today

    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

    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.

  4. Combining today's technologies provides for comprehensive management of volt/VAr assets

    Energy Technology Data Exchange (ETDEWEB)

    Dixon, M. [Beckwith Electric Co., Largo, FL (United States)

    2002-08-01

    Integration, automation and savvy planning are required in today's electric utility industry for the optimization of the distribution Volt/voltage adjusting rheostat (VAr) assets. Distributed intelligence should be considered. The basis of an automation platform for control of voltage and VAr assets at the local level is created by intelligence at the site of the control. The capabilities of the communication media to be used are to be thoroughly investigated when remote bypass or override of the local control is being implemented, preferring a very robust common public carrier network for infrastructure or the utility-owned private network. Such situations would occur in the case of voltage collapse, changes to system field assets after circuit switching when local intelligence needs to move faster, and transmission side support. A good centralized VAr dispatch program can be difficult to select, and the basis should be accurate measurement of system-wide parameters at all strategic locations throughout the distribution system. The minimum to be included is as follows: substation bus voltages and currents, feeder head voltages and currents, substation breaker status, transformer loading, voltages from as far along radial feeders as can be read, end of line voltages, and direction of power flow. The advantages of this optimization are the reduction of system losses, lower operating costs, an improvement of the power quality and the bottom-line profitability. 1 fig.

  8. Film and television in Croatia today: production, new technologies and the relationship with visual anthropology.

    Science.gov (United States)

    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.

    2015-01-01

    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...

    1999-01-01

    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.

    The purpose of the present project has been to study today's best available technology for biomass fired heating plants in the interval 0.5 to 10 MW from an emission point of view. Emission measurements have been conducted at 21 plants of different types and sizes, i.e. one stationary fluidized bed, fourteen boilers with moving grates, four boilers with fixed grates, one pellet burner and one boiler with a gasification oven. The plants were fired with different fuels: native fuels like wood chips, bark/sawdust, grass and refined fuels like briquettes and pellets. The plants were chosen to represent the best available and/or the most common technology. The flue gases were analyzed for CO, NO x , Total Hydrocarbons (THC), methane, ethylene, acetylene, ammonia, nitrous oxide, CO 2 and O 2 . The measurements were usually made at the heat loads and operating conditions given at the time of testing. However, in a few cases measurements were made at different loads and air settings

    Control systems of modern nuclear installations (including water-cooled, WCR) are based on programmable technologies. Most of control systems modernizations which are implemented at operating nuclear installations are also based on application of programmable technologies. Besides, a range of features and properties is defied for programmable technologies. These features and properties make licensing process more complicated, facilitate appearance of common cause failures, make safety evaluation procedures more complicated, etc. Also it is known that programmable technologies significantly extend the time periods for project realization of new power units construction and modernization of the existing power units, and also it involves rise of its value. Company RADIY has developed the Platform of digital equipment RADIY on FPGA-based technology. In the article there is a description of the features of FPGA-technology developed and applied by Company RADIY, features of the Platform RADIY and systems realized on its base, which allow to minimize significantly above-mentioned negative features and properties of programmable technologies. Technology which realized in Platform RADIY allows to solve the whole set of tasks of control (including regulation) and protection of nuclear installations. Platform RADIY is a combination of the best features of traditional programmable technologies and FPGA-technology. According to the opinion of the authors of this article the technology which is realized in Platform RADIY is the key factor for solving of control and protection tasks of nuclear installations in the nearest future.

    Highlights: ► Process integration with better modelling and more advanced solution methods. ► Operational changes for better environmental performance through optimisation. ► Identification of process integration technology for operational optimisation. ► Systematic implementation procedure of process integration technology. ► A case study with crude oil distillation to demonstrate the operational flexibility. -- Abstract: To reduce emissions in the process industry, much emphasis has been put on making step changes in emission reduction, by developing new process technology and making renewable energy more affordable. However, the energy saving potential of existing systems cannot be simply ignored. In recent years, there have been significant advances in process integration technology with better modelling techniques and more advanced solution methods. These methods have been applied to the new design and retrofit studies in the process industry. Here attempts are made to apply these technologies to improve the environmental performance of existing facilities with operational changes. An industrial project was carried out to demonstrate the importance and effectiveness of exploiting the operational flexibility for energy conservation. By applying advanced optimisation technique to integrate the operation of distillation and heat recovery in a crude oil distillation unit, the energy consumption was reduced by 8% without capital expenditure. It shows that with correctly identified technology and the proper execution procedure, significant energy savings and emission reduction can be achieved very quickly without major capital expenditure. This allows the industry to improve its economic and environment performance at the same time.

    The globalization of the pharmaceutical supply chain has introduced new challenges, chief among them, fighting the international criminal trade in fake medicines. As the manufacture, supply, and distribution of drugs becomes more complex, so does the need for innovative technology-based solutions to protect patients globally. Areas covered: We conducted a multidisciplinary review of the science/health, information technology, computer science, and general academic literature with the aim of identifying cutting-edge existing and emerging 'digital' solutions to combat fake medicines. Our review identified five distinct categories of technology including mobile, radio frequency identification, advanced computational methods, online verification, and blockchain technology. Expert opinion: Digital fake medicine solutions are unifying platforms that integrate different types of anti-counterfeiting technologies as complementary solutions, improve information sharing and data collection, and are designed to overcome existing barriers of adoption and implementation. Investment in this next generation technology is essential to ensure the future security and integrity of the global drug supply chain.

    After the famous 1983 discovery of intermediate W, Z 0 bosons it may be stated with certainty that W, Z 0 are entirely responsible for the production of neutrinos and for their interactions. Neutrino physics notions are presented from this point of view in the first four introductory, quite elementary, paragraphs of the paper. The following seven paragraphs are more sophisticated. They are devoted to the neutrino mass and neutrino mixing question, which is the most actual problem in today neutrino physics. Vacuum neutrino oscillations, matter neutrino oscillations and netrinoless double-decay are considered. Solar neutrino physics is discussed in some detail from the point of view of vacuum and matter neutrino oscillations. The role played by neutrinos in the Universe is briefly considered. In the last paragraph there discussed the probable observation by different groups of neutrinos connected with the Supernova 1987 A: the first observation of gravitational star collapse (at least the general rehearsal of such observation) opens up a new era in astronomy of today exerimental physics and astrophysics is presented at the end of the paper in the form of a Table

    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: Total installed electric power output of the existing thermal electric power plants in Uzbekistan is reaches 12 GW. Thermal electric power plants, working on organic fuel, produce around 88 % of the electricity in the country. The emission coefficient of CO 2 gases is 620 gram/kwph. Average electric efficiency of the thermal electric power plants is 32.1 %. The mentioned above data certifies, that the existing thermal electric power plants of Uzbekistan are physically and morally aged and they need to be retrofitted. Retrofitting of the existing thermal electric power plants can be done by several ways such as via including gas turbine toppings, by using solar technologies, etc. Solar thermal power is a relatively new technology which has already shown its enormous promise. With few environmental impacts and a massive resource, it offers a comparable opportunity to the sunniest Uzbekistan. Solar thermal power uses direct sunlight, so it must be sited in regions with high direct solar radiation. In many regions, one square km of land is enough to generate as much as 100-120 GWh of electricity per year using the solar thermal technology. This is equivalent to the annual production of a 50 MW conventional coal or gas-fired mid-load power plant. Solar thermal power plants can be designed for solar-only or for hybrid operation. Producing electricity from the energy in the sun's rays is a straightforward process: direct solar radiation can be concentrated and collected by a range of Concentrating Solar Power technologies to provide medium- to high temperature heat. This heat is then used to operate a conventional power cycle, for example through a steam turbine or a Stirling engine. Solar heat collected during the day can also be stored in liquid or solid media such as molten salts, ceramics, concrete or, in the future, phase-changing salt mixtures. At night, it can be extracted from the storage medium thereby continuing turbine operation. Currently, the

    2010-01-01

    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.

    The problems facing administrative courts in determining 'existing knowledge in science and technology' (No. 3 of paragraph 2 of sect. 7 of the Atomic Energy Law) cannot be solved by limiting the judicial establishment of facts. According to established law, in procedural or substantive law there is no foundation for doing so. Limits to this establishment of facts do result from the nature of the scientific process of understanding, which very often allows but the establishment of 'margins' pertaining to scientific opinions.

    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.

    Full Text Available This study aims to determine existing technology in cultivation of beef cattle in farmer group of Lembu Agung. Secondary data collected cover potential of area and livestock population, while primary data include number of livestock, maintenance system, feed management and reproduction performance. Data collected through Foccus Group Discussion (FGD method using a semi-structured questionnaire. Results of study showed that farmer group of Lembu Agung had 24 cows, consisting of 17 adult cows, 4 adult bulls and 3 calves, with a relatively low maintenance scale of 1-2 head. Maintenance system is still semi-intensive with minimal management especially in terms of providing adequate feeding throughout year. Feeding only rely on availability of natural grass and a small part of elephant grass planted in rice field area, with amount of green forage is only about 5-10 kg/head/day. Reproduction performance of parent with existing technology includes calving rate (60%; Body condition score (BCS of cow (2-2,5; Calving interval (18-24 months; Birth weight (15-18 and calf crop (40-50%. This study shows that feed problems are a limiting factor in cattle farming although potential for feed is sufficiently available but not yet optimally utilized, this has an impact on low productivity of cattle.

  12. Pulsars today

    Graham-Smith, F.

    1990-01-01

    The theory concerning pulsars is reviewed, with particular attention to possible evolution, life cycle, and rejuvenation of these bodies. Quantum liquids, such as neutron superfluids, and evidence for the existence of superfluid vortices and other internal phenomena are considered with particular attention to the Crab pulsar. Rate of change of the rotation rate is measured and analyzed for the Crab pulsar and the implications of deviations in the pulse times from those of a perfect rotator are examined. Glitches, the sudden increase in rotation rate of a pulsar that has previously exhibited a steady slowdown, are discussed and it is suggested that the movement of the superfluid core relative to the crust is responsible for this phenomenon. It is noted that radio waves from pulsars can be used to determine the intensity and structure of interplanetary and interstellar gas turbulence and to provide a direct measure of the strength of the interstellar magnetic field

  13. Low-energy office buildings using existing technology. Simulations with low internal heat gains

    Energy Technology Data Exchange (ETDEWEB)

    Flodberg, Kajsa; Blomsterberg, Aake; Dubois, Marie-Claude [Lund Univ. (Sweden). Div. of Energy and Building Design

    2012-11-01

    Although low-energy and nearly zero-energy residential houses have been built in Sweden in the past decade, there are very few examples of low-energy office buildings. This paper investigates the design features affecting energy use in office buildings and suggests the optimal low-energy design from a Swedish perspective. Dynamic simulations have been carried out with IDA ICE 4 on a typical narrow office building with perimeter cell rooms. The results from the parametric study reveal that the most important design features for energy saving are demand-controlled ventilation as well as limited glazing on the facade. Further energy-saving features are efficient lighting and office equipment which strongly reduce user-related electricity and cooling energy. Together, the simulation results suggest that about 48% energy can be saved compared to a new office building built according to the Swedish building code. Thus, it is possible, using a combination of simple and well-known building technologies and configurations, to have very low energy use in new office buildings. If renewable energy sources, such as solar energy and wind power, are added, there is a potential for the annual energy production to exceed the annual energy consumption and a net zero-energy building can be reached. One aspect of the results concerns user-related electricity, which becomes a major energy post in very low-energy offices and which is rarely regulated in building codes today. This results not only in high electricity use, but also in large internal heat gains and unnecessary high cooling loads given the high latitude and cold climate. (orig.)

  14. Role of advanced RF/microwave technology and high power switch technology for developing/upgrading compact/existing accelerators

    International Nuclear Information System (INIS)

    Shrivastava, Purushottam

    2001-01-01

    With the advances in high power microwave devices as well as in microwave technologies it has become possible to go on higher frequencies at higher powers as well as to go for newer devices which are more efficient and compact and hence reducing the power needs as well as space and weight requirement for accelerators. New devices are now available in higher frequency spectrum for example at C-Band, X-band and even higher. Also new devices like klystrodes/Higher Order Mode Inductive Output Tubes (HOM IOTs) are now becoming competitors for existing tubes which are in use at present accelerator complexes. The design/planning of the accelerators used for particle physics research, medical accelerators, industrial irradiation, or even upcoming Driver Accelerators for Sub Critical Reactors for nuclear power generation are being done taking into account the newer technologies. The accelerators which use magnetrons, klystrons and similar devices at S-Band can be modified/redesigned with devices at higher frequencies like X-Band. Pulsed accelerators need high power high voltage pulsed modulators whereas CW accelerators need high voltage power supplies for functioning of RF / Microwave tubes. There had been a remarkable growth in the development and availability of solid state switches both for switching the pulsed modulators for microwave tubes as well as for making high frequency switch mode power supplies. Present paper discusses some of the advanced devices/technologies in this field as well as their capability to make advanced/compact/reliable accelerators. Microwave systems developed/under development at Centre for Advanced Technology are also discussed briefly along with some of the efforts done to make them compact. An overview of state of art vacuum tube devices and solid state switch technologies is given. (author)

    2010-07-01

    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.

    In industrial applications of the sealed radioactive sources, there are two clearly definite branches for which these materials are utilized: radioactive sources utilized in fixed and in portable equipment. These devices are utilized in an endless number of applications and each time with more advanced technological systems. This requires a permanent improvement in the training of the responsible, and at the same time introduces an obligatory change to other intervention groups during the useful life of the device. The risks of accident, to the ones associated with the use of these equipment, though their rate of occurrence is low, they are errors during the operation, undue use, maintenance by personnel without knowledge, human type failures or carelessness and incidents occurred during the transportation. All these risks are surrounded by different groups of factors that influence during the sure use of the radioactive material inside the installation. Therefore the importance to establish aspects of Safety Culture, aptitude evaluations of the radiological security responsible, improvements introduction in quality and risks communication aspects, in agreement with the Argentine Republic regulations and the international requests, is emphasized. In the present paper all concepts about the radioactive material responsible election, the training, the factors that intervene during the operation, the installation obligations, insecurity situations and the changes or improvements that technology introduces, are referenced.

    The worldwide market for superconductive products may exceed $1 billion in 1987. These products are expanding the frontiers of science, revolutionizing the art of medical diagnosis, and developing the energy technology of the future. In general, today's customers for superconductive equipment want the highest possible performance, almost regardless of cost. The products operate within a few degrees of absolute zero, and virtually all are fabricated from niobium or niobium alloys-so far the high-temperature superconductors discovered in 1986 and 1987 have had no impact on these markets. The industry shows potential and profound societal impact, even without the new materials

    2012-01-01

    This report provides estimates of operational water withdrawal and water consumption factors for electricity generating technologies in the United States. Estimates of water factors were collected from published primary literature and were not modified except for unit conversions. The water factors presented may be useful in modeling and policy analyses where reliable power plant level data are not available. Major findings of the report include: water withdrawal and consumption factors vary greatly across and within fuel technologies, and water factors show greater agreement when organized according to cooling technologies as opposed to fuel technologies; a transition to a less carbon-intensive electricity sector could result in either an increase or a decrease in water use, depending on the choice of technologies and cooling systems employed; concentrating solar power technologies and coal facilities with carbon capture and sequestration capabilities have the highest water consumption values when using a recirculating cooling system; and non-thermal renewables, such as photovoltaics and wind, have the lowest water consumption factors. Improved power plant data and further studies into the water requirements of energy technologies in different climatic regions would facilitate greater resolution in analyses of water impacts of future energy and economic scenarios. This report provides the foundation for conducting water use impact assessments of the power sector while also identifying gaps in data that could guide future research. (letter)

    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.

    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

    2001-02-01

    The goal of this part of the Hybrid Control Room Project is to gain a perspective on the issues and problems that are an integral part of introducing new technology, automated systems, or support systems into nuclear power plant (NPP) control rooms, particularly when they are introduced on a system-by-system basis. For purposes of this project, hybrid control rooms are defined as those into which new technology, such as digital and computer-based controls are gradually incorporated as opposed to those that are completely, or nearly completely, refitted with new technology. Although the focus of this project is the introduction of computer based, digital systems into NPP control rooms, it is not possible to exclude the effects throughout the process that are inevitable when new technology is introduced anywhere in complex process control systems. Thus, this document examines the effects of such changes within the context of the organisation in which they occur, including the management of change, work procedures and work methods, communications and crew interaction, training, and the interdependent functions in the operational context.

    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

    If extraterrestrials exist in the depths of cosmic space, and are capable of interstellar communications, even space flight, there is no requirement that they be humanoid in form. However, certain humanoid capabilities would be advantageous for tool fashioning and critical to operating space craft as well as functioning under the disparate extreme conditions under which they may be forced to operate. They would have to be "gas breathing". The reasonable assumption that life based upon the same elements as Earth life requiring water stems from the unique properties of water that no other similar low molecular weight nonmetal hydride offers. Only water offers the diversity of chemical properties and reactivity, including the existence of the three common physical states within a limited temperature range of service to life, avoiding the issues presented by any alternatives. They must, like us, possess a large, abstract-thinking brain, and probably possess at least all the fundamental senses that humankind possess. They would also be carbon-based life, using oxygen as the electron sink of their biochemistry for the reasons considered. They most likely are homeothermic as us, though they may not necessarily be mammalian as we are. Their biochemistry could differ some from ours, perhaps presenting contact hazards for both species as discussed.

    A novel concept to produce a reasonable simulation of a fusion first wall/blanket test environment employing an existing nuclear facility, the Engineering Test Reactor at the Idaho National Engineering Laboratory, is presented. Preliminary results show that an asymmetric, nuclear test environment with surface and volumetric heating rates similar to those expected in a fusion first wall/blanket or divertor chamber surface appears feasible. The proposed concept takes advantage of nuclear reactions within the annulus of an existing test space (15 cm in diameter and approximately 100 cm high) to provide an energy flux to the surface of a test module. The principal reaction considered involves 3 He in the annulus as follows: n + 3 He → p + t + 0.75 MeV. Bulk heating in the test module is accomplished by neutron thermalization, gamma heating, and absorption reactions involving 6 Li in the blanket breeding region. The concept can be extended to modified core configurations that will accommodate test modules of different sizes and types. It makes possible development testing of first wall/blanket systems and other fusion components on a scale and in ways not otherwise available until actual high-power fusion reactors are built

    Homeless Mentally Ill (HMI) patients pose a challenge in treatment, management and rehabilitation services. HMI patients are often difficult to engage in treatment, and associated with relapse and rehospitalization, even after recovery. Family plays an important role in treatment engagement and care of the mentally ill person in India. Here, we report two unknown psychiatric patients who were reintegrated to their families using newer technologies with existing service. Newer technologies have helped in early identification of HMI families and reintegration into them. The early reintegration reduced the unnecessary detention of HMI patients inside the hospital after recovery. Copyright © 2017 Elsevier B.V. All rights reserved.

    This report is a review of decontamination technology applied by industry to radioactively contaminated components in the U.S.A. In addition some newer techniques under development or recently emerging are discussed. Mechanical, chemical, manual and other techniques such as electropolishing and ultrasonics are reviewed. Whilst the emphasis is mainly on non-destructive techniques for components some discussion of segmentation is included as this is inevitable during concrete decontamination; and also when decontamination of components occurs as part of a decommissioning programme the use of segmentation techniques may facilitate the process. A bibliography has been included to facilitate further reading. It is important to consider the relevance of the US data in this report to the United Kingdom both to the learning curve of development and the different nuclear reactor systems in the respective countries. The authors have therefore listed some conclusions and recommendations which have become apparent to them whilst undertaking the study. (U.K.)

    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.

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

    Antonino Recupero

    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.

    To design a patient data dashboard for the Department of Anesthesiology, Perioperative and Pain Medicine at Boston Children's Hospital that supports care integration across the healthcare system as described by the pediatric perioperative surgical home (PPSH) initiative. By using 360 Technology, patient data was automatically pulled from all available Electronic Health Record sources from 2005 to the present. The PPSH dashboard described in this report provides a guide for implementation of PPSH Clinical Care Pathways. The dashboard integrates several databases to allow for visual longitudinal tracking of patient care, outcomes, and cost. The integration of electronic information provided the ability to display, compare, and analyze selected PPSH metrics in real time. By utilizing the PPSH dashboard format the use of an automated, integrated clinical, and financial health data profile for a specific patient population may improve clinicians' ability to have a comprehensive assessment of all care elements. This more global clinical thinking has the potential to produce bottom-up, evidence-based healthcare reform. The experience with the PPSH dashboard provides solid evidence for the use of integrated Electronic Health Record to improve patient outcomes and decrease cost.

  15. Combination of existing and alternative technologies to promote oilseeds and pulses proteins in food applications

    Directory of Open Access Journals (Sweden)

    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.

    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.

    During the history of the Hanford Site, many structures were built that stored and transported liquids used for the production mission; some of these structures are still active. Active structures include underground storage tanks retention basins, and pipes and pipelines. Many of the liquids stored and transported in these structures are potentially hazardous to human health and the environment. Any leakage of liquids from active structures, has the added potential to mobilize contaminants in the unsaturated zone. Therefore, it is beneficial to monitor these structures for leaks. The purpose of tills report is to catalog existing and emerging technologies that have potential for the external monitoring of liquid leaks. The report will focus primarily on the needs at the Hanford Site tank farms that are located in the 200 Areas, but will also be relevant to other Hanford Site facilities. Leak detection systems, both external and internal, are currently used at some Hanford facilities. This report focuses on the detection of leaks as they migrate into the soils surrounding the facilities

  13. Improving productivity in agriculture. One of the five key areas to sustainable development where progress is possible with the resources and technologies at our disposal today

    International Nuclear Information System (INIS)

    2002-01-01

    Despite progress made since the 1996 World Food Summit that set the goal of halving the number of undernourished people by the 2015, serious food insecurity persists in many parts of the world. Although more food is being produced worldwide than ever before, some 800 million people are still chronically malnourished. Improving agricultural productivity is a driving force for both economic and social development. When agriculture falters, income sources are lost, social ties are disrupted, and, as a result, societies become more mobile. Up-to-date technologies, improved plant and animal stock, and better soil and water management practices not only combat food insecurity, they are also important to achieving sustainable agriculture practices essential to maintaining an appropriate balance between conservation and use of all the resources required to grow crops and raise livestock. Through its programme in Food and Agriculture operated with the Food and Agriculture Organization (FAO), the International Atomic Energy Agency (IAEA) works to enhance capacities at national and international levels for identifying and alleviating constraints to sustainable food security by facilitating development and adoption of nuclear and related biotechnologies. With an annual budget of nearly $10 million, this programme helps Member States to improve productivity in agriculture, particularly through better water and soil management practices, efficient crop nutrition, and control of insect pests

    The role of knee arthrography today is demonstrated and technical problems are discussed. Among a lot of variants the position of the patient and the choice of contrast media play a great part concerning the result of the examination. Mild complications occur in 0.25% of the examinations, severe and live threatening complications are extremely rare. Diagnosis of meniscal lesions is most important for knee arthrography; arthroscopy and arthrography are complementary examinations and not mutually exclusive, they achieve combined an accuracy of 97-98%. In the same way arthrography is able to evaluate the condropathy of the femoro-tibial joint, whereas accuracy of arthroscopy in the diagnosis of patellar chondropathy is much higher. There is a great reliability of arthrography regarding the evaluation of lesions of the capsule, but accuracy in lesions of the cruciate ligaments is low. Arthrography is very suitable for evaluation of Baker-cysts, since indications for almost occuring internal derangement of the knee are even available. Knee arthrography is a complex and safe procedure with very less discomfort for the patient; it has a central position in the evaluation of lesions of the knee. (orig.) [de

    Forsman, L; Eriksson, A

    2001-01-01

    Background—Skateboarding injuries have increased with the rise in popularity of the sport, and the injury pattern can be expected to have changed with the development of both skateboard tricks and the materials used for skateboard construction. Objective—To describe the injury pattern of today. Methods—The pattern of injuries, circumstances, and severity were investigated in a study of all 139 people injured in skateboarding accidents during the period 1995–1998 inclusive and admitted to the University Hospital of Umeå. This is the only hospital in the area, serving a population of 135 000. Results—Three of the 139 injured were pedestrians hit by a skateboard rider; the rest were riders. The age range was 7–47 years (mean 16). The severity of the injuries was minor (AIS 1) to moderate (AIS 2); fractures were classified as moderate. The annual number of injuries increased during the study period. Fractures were found in 29% of the casualties, and four children had concussion. The most common fractures were of the ankle and wrist. Older patients had less severe injuries, mainly sprains and soft tissue injuries. Most children were injured while skateboarding on ramps and at arenas; only 12 (9%) were injured while skateboarding on roads. Some 37% of the injuries occurred because of a loss of balance, and 26% because of a failed trick attempt. Falls caused by surface irregularities resulted in the highest proportion of the moderate injuries. Conclusions—Skateboarding should be restricted to supervised skateboard parks, and skateboarders should be required to wear protective gear. These measures would reduce the number of skateboarders injured in motor vehicle collisions, reduce the personal injuries among skateboarders, and reduce the number of pedestrians injured in collisions with skateboarders.

    1996-01-01

    Plasma Technology, Inc. (PTI), a Santa Fe, New Mexico corporation has developed the Plasma Energy Recycle and Conversion (PERC)trademark treatment process as a safe and environmentally clean alternative to conventional thermal destruction technologies. The PERC trademark treatment process uses as its heat source an advanced Induction Coupled Plasma (ICP) torch connected to a reaction chamber system with an additional emission control system. For example, organic-based gas, liquid, slurry, and/or solid waste streams can be converted into usable or even salable products while residual emissions are reduced to an absolute minimum. In applications for treatment of hazardous and radioactive waste streams, the PERC system could be used for destruction of the hazardous organic constituents and/or significant waste volume reduction while capturing the radioactive fraction in a non-leachable form. Like Direct Current (DC) and Alternating Current (AC) arc plasma systems, ICP torches offer sufficient energy to decompose, melt and/or vitrify any waste stream. The decision for an arc plasma or an IC plasma system has to be made on a case by case evaluation and is highly dependent on the specific waste stream's form and composition. Induction coupled plasma technology offers one simple, but significant difference compared to DC or AC arc plasma systems: the ICP torch is electrodeless. To date, enormous research effort has been spent to improve the lifetime of electrodes and the effectiveness of related cooling systems. Arc plasma systems are established in research laboratories worldwide and are approaching a broad use in commercial applications. ICP technology has been improved relatively recently, but nowadays offers complete new and beneficial approaches in the field of waste conversion and treatment

    The purpose of this critical review is to summarise the evidence for the following technologies/strategies related to diagnosing or managing sports-related concussion: quantitative EEG, functional neuroimaging, head impact sensors, telemedicine and mobile devices. MEDLINE, PubMed, Cochrane Controlled Trials Registers, SportDiscus, EMBASE, Web of Science and ProQuest databases. Primary search keywords were concussion, sports concussion and mild traumatic brain injury. The keywords used for secondary, topic specific searches were quantitative electroencephalography, qEEG, functionalMRI, magnetoencephalography, near-infrared spectroscopy, positron emission tomography, single photon emissionCT, accelerometer, impact sensor, telemetry, remote monitoring, robotic medicine, telemedicine, mobile device, mobile phone, smart phone and tablet computer. The primary search produced 8567 publications. The secondary searches produced nine publications that presented original data, included a comparison group in the study design and involved sports-related concussion. Four studies spoke to the potential of qEEG as a diagnostic or management tool, while five studies addressed the potential of fMRI to be used in the same capacity. Emerging technologies and novel approaches that aid in sports concussion diagnosis and management are being introduced at a rapid rate. While some technologies show promise, their clinical utility remains to be established.

    With the appetite for living and dead natural resources, the political and economical interest concerning the Antarctic increases throughout the world. There are three interrelated main subjects accounting for the international interest: The shelf tectonic puzzle of the original continent of Gondwana, where the Antarctic is situated in the centre, between Australia, South Africa and South America, and the hopes concerning the existence of mineral resources under the ice of the Antarctic are based thereon. The Antarctic forms the biggest unified living space of the world. (orig.)

    2008-01-01

    The first part of a study concerning innovative intervention techniques for dissipate a share of the input seismic energy compatible with the preservation of existing buildings, including historical and monumental constructions, is presented in this paper. The case of a typical scheme of a long-bay box-like masonry building fitted with a dissipative floating roof is analyzed. In the examined building a wide simulation analysis has shown the achievement of a very satisfying performance. Furthermore, the effectiveness of the system can be maximized by means of active or semi-active devices implemented in the floating roof and a significant reduction of the seismic impact on the building can be obtained compared with non-controlled or simply passively controlled structure. The results prove the remarkable increase of the energy dissipation capability of the system, as well as the reduction of structural damage, independently of any specific strengthening intervention

    One of the important effects associated with acid precipitation related pollutants is interference with radiation transfer (light transmission) in the atmosphere. An obvious result of such interference is visibility degradation--the impairment of atmospheric clarity or of the ability to perceive form, texture, and color. Climate modification constitutes another, somewhat less obvious, result. The purpose of the NAPAP State of Science/Technology report is to summarize current knowledge regarding these radiation transfer effects. Although the report focuses mainly on visibility issues, it does encompass the emerging field of climate modification. The links between the acid rain problem and radiation transfer effects, although indirect, are quite strong. The principal link is through sulfur dioxide emissions and sulfate aerosols. A secondary link occurs through nitrogen oxide emissions

    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.

Cogema is involved in all the phases of the nuclear fuel cycle except for the manufacture of the fuel itself, a gap that it is planning to fill. Cogema's discovery of the Coutras deposit in the Gironde is 'the good news' of the year. Work on the Eurodif uranium enrichment plant at Tricastin is almost finished and by the end of 1981 it will be operating at its full capacity of 10,8 million SWU. On the processing side, work on expanding existing facilities has begun (UP2 800 and UP3). In 1985 La Hague's foreign clients UP2 will process 1,200 tons and UP3 6000 tons [fr

    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

    Radioactive hydrogen isotope, tritium is one of the radionuclides which is the most released in the environment during the normal operation of nuclear facilities. The increase of nuclear activities and the development of future generations of reactors, like the EPR and ITER, would lead to a significant increase of tritium effluents in the atmosphere and in the natural waters, thus raising many worries and questions. Aware about the importance of this question, the national association of local information commissions (ANCLI) wished to make a status of the existing knowledge concerning tritium and organized in 2008 a colloquium at Orsay (France) with an inquiring approach. The scientific committee of the ANCLI, renowned for its expertise skills, mobilized several nuclear specialists to carry out this thought. This book represents a comprehensive synthesis of today's knowledge about tritium, about its management and about its impact on the environment and on human health. Based on recent scientific data and on precise examples, it treats of the overall questions raised by this radionuclide: 1 - tritium properties and different sources (natural and anthropic), 2 - the problem of tritiated wastes management; 3 - the bio-availability and bio-kinetics of the different tritium species; 4 - the tritium labelling of environments; 5 - tritium measurement and modeling of its environmental circulation; 6 - tritium radio-toxicity and its biological and health impacts; 7 - the different French and/or international regulations concerning tritium.

    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.

    A devastating earthquake measuring 7.2 on the JMA (Japan Meteorological Agency) magnitude hit the southern Hyogo Prefecture on January 17, 1995. This earthquake, the worst in Japan since the Great Kanto Earthquake in 1923, brought great disaster and destruction to the Hanshin area and Awajishima Island. Most of the damage to concrete and steel structures occurred in buildings designed according to former building codes. Fewer collapses occurred in buildings designed under current building code that have more severe seismic requirements. Existing buildings should be assessed by their seismic potentiality, and retrofitted to escape damage in severe earthquakes such as the Great Hanshin Earthquake. New technology for assessing and retrofitting existing buildings was developed to improve resisting performance in response to severe earthquakes. Earthquake Load or motion exceeding current requirements can be supplied to assess and retrofit existing buildings if a client wants their buildings to exhibit much stronger seismic resistance. The retrofit technologies, such as a base isolation system for whole building, vibration control bracing system with steel damper, and base isolation floor system for computer equipments, can be applied to existing buildings. 11 refs., 9 figs., 8 tabs.

    Pilot cable is originally used for utility protection. Then, pilot cable is further utilized for SCADA communication with low frequency PSK modem in the early 1990. However, the quality of pilot cable communication drops recently. Pilot cable starts to deteriorate due to aging and other unknown factors. It is also believed that the presence of induced voltage causes interference to existing modem communication which operates at low frequency channel. Therefore, BPL (Broadband Power Line), EtherLoop and SHDSL (Symmetrical High-speed Digital Subscriber Line) modem technology are proposed as alternative communication solutions for pilot cable communication. The performance of the 3 selected technologies on existing pilot cable circuits under the presence of induced voltage are measured and compared. Total of 11 pilot circuits with different length and level of induced voltage influence are selected for modem testing. The performance of BPL, EtherLoop and SHDSL modem technology are measured by the delay, bandwidth, packet loss and the long term usability SCADA (Supervisory Control and Data Acquisition) application. The testing results are presented and discussed in this paper. The results show that the 3 selected technologies are dependent on distance and independent on the level of induced voltage.

    Technical developments can both change the methods of dealing with existing conflicts, and cause new conflicts. Meyer-Abich analyzes five conflicts caused by the technological development in the solution of which the constitutional, liberal, and democratic protection of fundamental rights is not at all guaranteed. Meyer-Abich thinks that these new conflicts can be solved in the framework of the liberal constitutional state, if legal and political consequences are taken in order to guarantee the uncharged protection of fundamental rights under changing conditions. The necessary reforms can, however, only be realized if the way how state and science see themselves changes. Both have to give up their one-sidedness into which have been pushed by conflict which havbe been caused by the scientific and technical development. Only then it will be possible to solve the jemerging conflicts without eopardizing the integritiy of the society. (orig.) [de

    Recent technical advances in planning and delivering IMRT provide an unprecedented means for producing exquisitely shaped radiation doses that closely conform to the tumor dimensions while sparing sensitive structures. The development of 3D CRT and IMRT places more stringent requirements on the accuracy of beam targeting. In practice, large uncertainties exist in tumor volume delineation and in target localization due to intra- and inter-organ motions. The utility of modern radiation technologies, such as 3D CRT and IMRT, cannot be fully exploited without eliminating or significantly reducing these uncertainties. The need to improve targeting in radiation treatment has recently spurred a flood of research activities in image-guided radiation therapy (IGRT)

    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.

Today there very definitely is a break point in the application of equipment at approximately -120 0 F or 189 0 K. Other technologies are generally utilized below this level. However, with market potential comes invention and breakthroughs in refrigeration can also occur. Today standard refrigeration systems are cost effective, reliable and produced in the millions for high temperature applications of +10 0 F to +40 0 F evaporator temperature. Lower temperatures require additional hardware, consume additional power and are produced today in limited quantities for special applications

    The use of bioremediation for full-scale cleanup has increased dramatically throughout the past 10 years. This growth in activity is expected to continue through the year 2000. It is estimated that fewer than 10 companies offered field-level bioremedial services prior to 1985. Although the market today still is dominated by a small number of companies, the total number of firms claiming to offer services and/or products for bioremediation purposes has grown to over 1,000. It is estimated that aggregate bioremediation revenues for 1994 through 2000 will equal $2 to $3 billion (1994 dollars). This revenue will be generated in the initial part of this 7-year period primarily from underground storage cleanup, with revenues from hazardous waste sites becoming an increasingly important factor by accounting for the majority of revenues in the latter years. Market opportunities exist in technology development and implementation including biosparging, centralized treatment facilities for petroleum-contaminated soils, biofilters, and improvements in the cost-effectiveness of the technology

    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.

    Low-educated patients are disadvantaged in using questionnaires within the health care setting because most health-related questionnaires do not take the educational background of patients into account. The Dutch Talking Touch Screen Questionnaire (DTTSQ) was developed in an attempt to meet the needs of low-educated patients by using plain language and adding communication technology to an existing paper-based questionnaire. For physical therapists to use the DTTSQ as part of their intake procedure, it needs to generate accurate information from all of their patients, independent of educational level. The aim of this study was to get a first impression of the information that is generated by the DTTSQ. To achieve this goal, response processes of physical therapy patients with diverse levels of education were analyzed. The qualitative Three-Step Test-Interview method was used to collect observational data on actual response behavior of 24 physical therapy patients with diverse levels of education. The interviews included both think-aloud and retrospective probing techniques. Of the 24 respondents, 20 encountered one or more problems during their response process. The use of plain language and information and communication technology (ICT) appeared to have a positive effect on the comprehensibility of the DTTSQ. However, it also had some negative effects on the interpretation, retrieval, judgment, and response selection within the response processes of the participants in this study. No educational group in this research population stood out from the rest in the kind or number of problems that arose. All respondents recognized themselves in the outcomes of the questionnaire. The use of plain language and ICT within the DTTSQ had both positive and negative effects on the response processes of its target population. The results of this study emphasize the importance of earlier recommendations to accompany any adaption of any questionnaire to a new mode of delivery by

    This paper introduces new insights into the hydrochemical functioning of lowland river-systems using field-based spectrophotometric and electrode technologies. The streamwater concentrations of nitrogen species and phosphorus fractions were measured at hourly intervals on a continuous basis at two contrasting sites on tributaries of the River Thames, one draining a rural catchment, the River Enborne, and one draining a more urban system, The Cut. The measurements complement those from an existing network of multi-parameter water quality sondes maintained across the Thames catchment and weekly monitoring based on grab samples. The results of the sub-daily monitoring show that streamwater phosphorus concentrations display highly complex, seemingly chaotic, dynamics under storm conditions dependent on the antecedent catchment wetness, and that diurnal phosphorus and nitrogen cycles occur under low flow conditions. The diurnal patterns highlight the dominance of sewage inputs in controlling the streamwater phosphorus and nitrogen concentrations at low flows, even at a distance of 7 km from the nearest sewage works in the rural, River Enborne, and that the time of sample collection is important when judging water quality against ecological thresholds or standards. An exhaustion of the supply of phosphorus from diffuse and septic tank sources during storm events was evident and load estimation was not improved by sub-daily monitoring beyond that achieved by daily sampling because of the eventual reduction in the phosphorus mass entering the stream during events. The dominance of respiration over photosynthesis in The Cut indicated a prevalence of heterotrophic algae, and the seasonal patterns in respiration and photosynthesis corresponded with those of temperature and light in this nutrient over-enriched stream. These results highlight the utility of sub-daily water quality measurements but the deployment of modified wet-chemistry technologies into the field was limited

  16. Today's threat and tomorrow's reaction

    Moore, L.R.

    2002-01-01

    Full text: The events of September 11 have only confirmed our past nightmares and warnings to industries, agencies, and governments. The threat of even more significant catastrophic attacks, using nuclear materials, was just as real ten years ago, as it is today. In many cases, our vulnerability remains the same as years ago. There is a dire need for all organizations to agree upon threats and vulnerabilities, and to implement appropriate protections, for nuclear materials or other 'means' to achieve an event of mass destruction. All appropriate organizations (industries, agencies, and governments) should be able to define, assess, and recognize international threats and vulnerabilities in the same manner. In complimentary fashion, the organizations should be able to implement safeguards against this consistent generic threat. On an international scale the same threats, and most vulnerabilities, pose high risks to all of these organizations and societies. Indeed, in today's world, the vulnerabilities of one nation may clearly pose great risk to another nation. Once threats and vulnerabilities are consistently recognized, we can begin to approach their mitigation in a more 'universal' fashion by the application of internationally recognized and accepted security measures. The path to recognition of these security measures will require agreement on many diverse issues. However, once there is general agreement, we can then proceed to the acquisition of diverse national and international resources with which to implement the security measures 'universally' to eliminate 'weak-links' in the chain of nuclear materials, on a truly international scale. I would like to discuss: developing a internationally acceptable 'generic' statement of threat, vulnerability assessment process, and security measure; proposing this international statement of threat, vulnerability assessment process, and appropriate security measures to organizations (industries, agencies, and governments

  18. Religious Renaissance in China Today

    Directory of Open Access Journals (Sweden)

    Richard Madsen

    2011-01-01

    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.

    2012-05-01

    Full Text Available This paper is about the reconciliation of cultural analysis with political economy in Marxist-inspired research on communications. It traces how these two traditions became separated with the development of a one-dimensional and consumerist cultural studies, on the one-hand, and a more classically Marxist political economy of communications, on the other hand, that was accused of holding a simplistic and erroneous concept of ideology. The paper defends a conception of ideology as distorted communication motivated by unequal power relations and sketches a multidimensional mode of cultural analysis that takes account of the moments of production, consumption and textual meaning in the circulation of communications and culture. In accordance with this framework of analysis, the cool-capitalism thesis is outlined and illustrated with reference to Apple, the ‘cool’ corporation. And, the all-purpose mobile communication device is selected as a key and urgent focus of attention for research on commodity fetishism and labour exploitation on a global scale today.

    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.

    The main emphasis of this presentation and paper is to address why experts believe that today's operating nuclear power reactors are much safer than they were 10 or 20 years ago. There is strong evidence to support this belief for the power reactors now operating in all of the advanced countries, and in many of the less developed countries too, although in a few of these latter countries there are continuing safety concerns. The paper will present recent and historical data from the U.S., a discussion of what the data mean and why, and a perspective about what events and trends have been the causes for the major safety improvements that have occurred. The extension of the conclusion to other countries will also be discussed. Finally, the reasons why safety-improvement programs must continue in some of the less-developed countries are described

    Meeting the growing demand for energy, and electricity in particular, while addressing the need to curb greenhouse gas emissions and to ensure security of energy supply, is one of the most difficult challenges facing the world's economies. No single technology can respond to this challenge, and the solution which policy-makers are seeking lies in the diversification of energy sources. Although nuclear energy currently provides over 20% of electricity in the OECD area and does not emit any carbon dioxide during production, it continues to be seen by many as a controversial technology. Public concern remains over its safety and the management of radioactive waste, and financing such a capital-intensive technology is a complex issue. The role that nuclear power will play in the future depends on the answers to these questions, several of which are provided in this up-to-date review of the status of nuclear energy, as well as on the outcome of research and development on the nuclear fuel cycle and reactor technologies

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?

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.

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.

    Its nearly one year and a half since digital imaging/radiography was introduced in Kenya mainly in Nairobi. the technology is becoming an increasingly effective and acceptable modality of producing radiographs from the traditional conventional radiography in use to date. the digital radiography offers numerous advantages that have been noted for the short period over the conventional way. For instance radiographs are produced in real time (less than 3 minutes), by so doing the technology has eliminated the wait for the processing period. the radiation exposure to the patient under the radiological examination is reduced as much as 90% from the traditional conventional film taking. The cost, labour and record-keeping necessary to maintain a chemical processor and darkroom operations are as well eliminated. The cost of purchasing and disposing of film wastes/darkroom processing chemicals, which are environmentally hazardous, also become unnecessary.digital radiography technology makes the digital images comparable to other images on the screen at that instant making both the patient and the clinician easily access images when needed. digital receptors have also replaced the cassette containing intensifying screens and film that is used in conventional radiography

    Today's remote handling technology was developed in response to the remote maintenance (RM) requirements of the fission community's nuclear fuel recycle process. The needs of the fusion community present new challenges to the remote handling experts of the world. New difficulties are superimposed on the difficulties experienced in maintaining fission processes. Today's technology must be enhanced to respond to the RM needs of these future huge investments. This paper first discusses the current RM needs for fusion based on existing facilities and designs of future machines. It then exposes the gap between these requirements and existing RM technology and recommends ways to extend the state of the art to close this gap

    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.

    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.

The main point of the explanations is nuclear energy and power supply the basic thoughts of which are explained in detail. A general view at the present situation on the individual energy sections shows that by using regenerative energy sources and energy savings only the increasing energy need cannot be met. Also in the case of coal, when having used it for a long time through the technologies of gasification and liquidation, its quantitative limits will be seen sooner than it would be the case otherwise. For long terms, nuclear energy is the only way to guarantee the mankind a relatively rishless supply of energy in the generation of power and process heat, especially when the fast breeders are used.

    At present space biology research in Russia is making significant progress in several areas of high priority. Gravitational biology. In April-May 2013, a successful 30-day flight of the biological satellite (biosatellite) Bion-M1 was conducted, which carried rodents (mice and gerbils), geckos, fish, mollusks, crustaceans, microorganisms, insects, lower and higher plants, seeds, etc. The investigations were performed by Russian scientists as well as by researchers from NASA, CNES, DLR and South Korea. Foton-M4 carrying various biological specimens is scheduled to launch in 2014. Work has begun to develop science research programs to be implemented onboard Bion-M2 and Bion-M3 as well as on high apogee recoverable spacecraft.

  4. Botulinum toxin: yesterday, today, tomorrow

    Directory of Open Access Journals (Sweden)

    A. R. Artemenko

    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.

    1988-01-01

    This report investigates methods to utilize existing bulk tobacco kilns for curing (drying) of shelled corn, peanuts, and baled hay. In recent years Ontario tobacco producers have had to reduce production levels due to a declining demand for flue-cured tobacco. Many tobacco producers are currently diversifying into other crops. Some of these crops require curing and/or storage. Because of high capital costs to purchase conventional curing and/or storage facilities, tobacco producers wish to reduce their initial diversification costs by modifying their existing tobacco kilns (tobacco drying structures) and/or tobacco storage barns for this purpose. The investigation included high profile and low profile downdraft stick kilns, bulk kilns, and tobacco storage (pack) barns. Corn, peanuts, and hay were considered in relation to bulk kiln specifications and modifications, handling, drying and storage methods, energy requirements, cost, and quality of end product. The conclusions drawn from the study of each product are presented. Results from the projects indicate that: shelled corn can be dried from about 26% moisture content (w.b.) or less; baled hay can be dried from about 27% moisture content (w.b.) or less; and peanuts cured at airflow rates ranging from 169 to 645 l/s/m/sup 3/ of peanuts exhibited no significant differences when evaluated for appearance and flavour. 1 ref., 23 figs., 15 tabs.

    Kumar Khanna, Vinod

    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.

    As the millennium approaches, the future of the nuclear power generation appears desolate. Today's nuclear executives are facing challenges resulting from worldwide change and have forced utilities to reevaluate their corporation's future directions. The nuclear industry must be competitive more than ever to address today's rapid changing marketplace and pressures exerted from: regulatory reformation; increased competition; changes in technology; customer evolution; and globalization. These factors have compelled nuclear executives to address questions such as: What impact will these changes have on today's marketplace, and on my corporation? What will characterize tomorrow's successful nuclear facility? How can today's nuclear corporation compete in tomorrow's marketplace? Will my corporation survive? (author)

    2016-12-01

    Full Text Available Today, more students in the US are attending university than ever before. An unprecedented number of these students were born digital—meaning digital technologies have been a constant feature in their lives. For these young adults, information literacy competencies are always being formed, practiced, and learned. Project Information Literacy (PIL is a series of ongoing quantitative and qualitative research studies in the US that investigates what it is like to be a university student in the digital age. This research study has investigated how students find information and conduct research—in their words and through their experiences—for coursework, use in their everyday lives, and, once they graduate, in the workplace and their communities. Since 2008, more than 11,000 university students at nearly 60 US higher education institutions have been surveyed or interviewed, making PIL the largest study of information literacy ever conducted. Results from PIL’s studies have concluded students’ information competencies are put to the test in the vast information landscape they inhabit. Furthermore, finding and using information is exponentially more complex than it was a generation ago, especially since the information landscape has shifted from one of scarce resources to one of overload. In this keynote, five research takeaways were presented from PIL’s eight studies: (1 Students find research more difficult than ever before, (2 getting started is the hardest part of research, (3 frustrations begin with finding context, i.e., big picture, information-gathering, language, and situational context, (4 search strategies are based on predictability, familiarity, and efficiency, and (5 evaluation is the one information skills most learn to use. Discussion included implications of these findings for teaching, learning, work, and librarianship in the 21st century.

  15. Management options for implementing a basic and applied research program responsive to CS technology base needs. Task VIII. Review existing CS materials R and D programs

    Energy Technology Data Exchange (ETDEWEB)

    1980-02-28

    Possibilities for setting up a basic and applied research program that would be responsive to the Conservation and Solar energy base needs are considered with emphasis on the area of materials research. Several organizational arrangements for the implementation of this basic and applied research program are described and analyzed. The key functions of the system such as resources allocation, and program coordination and management follow from two fundamental characteristics: assignment of lead responsibility (CS and the Office of Energy Research, ER); and nature of the organizational chain-of-command. Three options are categorized in terms of these two characteristics and discussed in detail. The first option retains lead responsibility in ER, with CS personnel exercising sign-off authority and filling the coordination role. Option 2 places lead responsibility with CS program office management, and utilizes the existing chain-of-command, but adds a Basic and Applied Research Division to each program office. Option 3 also places lead responsibility with CS, but within a new Office of Basic and Applied Research, which would include a Research Coordinator to manage interactions with ER, and Research Managers for each CS program area.

    2014-01-22

    To improve the knowledge on a variety of severe disorders, research has moved from the analysis of individual proteins to the investigation of all proteins expressed by a tissue/organism. This global proteomic approach could prove very useful: (i) for investigating the biochemical pathways involved in disease; (ii) for generating hypotheses; or (iii) as a tool for the identification of proteins differentially expressed in response to the disease state. Proteomics has not been used yet in the field of respiratory research as extensively as in other fields, only a few reproducible and clinically applicable molecular markers, which can assist in diagnosis, having been currently identified. The continuous advances in both instrumentation and methodology, which enable sensitive and quantitative proteomic analyses in much smaller amounts of biological material than before, will hopefully promote the identification of new candidate biomarkers in this area. The aim of this report is to critically review the application over the decade 2004-2013 of very sophisticated technologies to the study of respiratory disorders. The observed changes in protein expression profiles from tissues/fluids of patients affected by pulmonary disorders opens the route for the identification of novel pathological mediators of these disorders.

    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.)

    2017-08-01

    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.

    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.

    1993-09-01

    Universal Precautions dictate sterilization for all invasive equipment that break the blood barrier; however, current methods of sterilization, such as steam and ethylene oxide gas (ETO), are not compatible with many of the delicate, heat-sensitive surgical instruments used in modern health care. In addition, traditional sterilization methods are often too time consuming for practical use in the operating room. Clearly, new sterilization processes need to be developed. In this article, the criteria modern sterilization processes must meet and how some manufacturers plan to meet this challenge are discussed. In addition, the pros and cons of using peracetic acid (the newest sterilization process currently available) are examined.

    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.

  4. [Competitiveness in science. Today, tomorrow, and forever].

    2000-01-01

    Paternalistic governments and highly bureaucratized administrations produce mediocre science policy decisions that often allow for the co-existence of potentially competitive scientists alongside with those that are not. This invariably results in failure to produce significant research. It seems apparent therefore, that policy change aiming at improving science and technology must begin with intensification of the level of individual competitiveness. Nations that have internationally competitive levels of technical and scientific activity such as Japan, USA and Canada, share in common certain features that foster individual competitiveness despite the fact that their socioeconomic basis are vastly different. These common features include administrative continuity, very high academic standards and a highly educated work force. The scientist's emotional cost in competitive environments is high but there seems to be no alternative given the sophistication of the topics that are dealt with in formerly purely descriptive sciences such as biomedicine, and given the enormous speed of electronic communications. The role of governments in fostering science and technology should be mainly concerned with conducting a sound fiscal policy in order to provide for the needs of education and scientific activity. Governments can also play a key role in insuring that science remains competitive through the delineation of rules that increase individual competitiveness rather than with policy schemes that fail to directly address the responsibility of the individual. Policies to increase individuals' performance may prove costly to politicians given that these adjustments imply unpopular decisions regarding an increase in academic performance expectation beginning in high school and the re-assignment of functions of individuals or institutions that do not meet international productivity criteria.

  5. Energy supply today and tomorrow, national and global

    2003-01-01

    A status report about 'Energy Supply Today and Tomorrow, National and Global' focuses mainly on global aspects. Today's world energy consumption is dominated by more than 80% of fossil sources of energy followed by so-called non-commercial energies, such as wood and plant and animal wastes, contributing 10%; nuclear power, 7%; and hydroelectric power, 2%. The development of energy consumption until the middle of this century will continue to be driven by the further growth of the world population, and by the need to meet the rising demand for energy in the developing countries. Because of their availability and flexible uses, oil, natural gas, and coal as fossil sources of energy will continue to meet a considerable share of the requirement. The use of nuclear power, a source meeting all criteria, such as safety, waste management, and competitiveness, is both justifiable and desirable. Restrictive decisions about nuclear power taken today must not impair the freedom of choice of future generations. Using renewable energies is just as desirable as increasing energy efficiency; however, the technical and physical potentials available for this purpose should not be overrated. This makes it imperative to protect the supply of energy 'in this difficult interim phase' with all the options available, and to open up prospects for the future, also by conducting the appropriate energy and environmental research. The balance between continuity of supply, environmental compatibility, and competitiveness must be taken into account in this effort. In the second half of the 21 st century, it is possible that energy consumption will stabilize when the world's population ceases to grow. New technologies, some of which may not even be known today or may still be under development, could then pave the way for an energy supply system which, in toto, would be less of a burden on the environment.

    Gouvela, John

    2004-01-01

    Experience and knowledge gained from ongoing maintenance of Space Shuttle Flight Software and new development projects including Cockpit Avionics Upgrade are applied to projected needs of the National Space Exploration Vision through Spiral 2. Lessons learned from these current activities are applied to create a sustainable, reliable model for development of critical software to support Project Constellation. This presentation introduces the technologies, methodologies, and infrastructure needed to produce and sustain high quality software. It will propose what is needed to support a Vision for Space Exploration that places demands on the innovation and productivity needed to support future space exploration. The technologies in use today within FSW development include tools that provide requirements tracking, integrated change management, modeling and simulation software. Specific challenges that have been met include the introduction and integration of Commercial Off the Shelf (COTS) Real Time Operating System for critical functions. Though technology prediction has proved to be imprecise, Project Constellation requirements will need continued integration of new technology with evolving methodologies and changing project infrastructure. Targets for continued technology investment are integrated health monitoring and management, self healing software, standard payload interfaces, autonomous operation, and improvements in training. Emulation of the target hardware will also allow significant streamlining of development and testing. The methodologies in use today for FSW development are object oriented UML design, iterative development using independent components, as well as rapid prototyping . In addition, Lean Six Sigma and CMMI play a critical role in the quality and efficiency of the workforce processes. Over the next six years, we expect these methodologies to merge with other improvements into a consolidated office culture with all processes being guided by

    1995-01-01

    In the power generation industry, non utility generators (NUG's) comprise a significant portion of new generation growth as electricity demands exceed existing utility capacities. These NUG's are developed by customers with widely varying experiences; bankers, lawyers, architect engineers, original equipment manufacturers, and other organizations involved in such diverse industries as petrochemical, pulp and paper, and steel making. The demands of these customers can be significantly varied in terms of features such as capacity factor, operability, maintainability, equipment redundancy, acceptable design practices, and many others. In addition, both the utility and NUG industries demand flexibility due to external influences such as regulatory policies, environmental conditions new design technologies, and emerging global markets. All of these factors are subject to wide variation across different market regions and even within a given region. This paper discusses the development of a reference plant design approach which focuses on customer flexibility while maximizing the use of proven designs. This approach allows basic system designs to be modified in a modular fashion to meet the differing demands of utility and NUG customers

    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.

  11. The Prospects of Radical Change Today

    Slavoj Žižek

    2018-05-01

    Full Text Available In this contribution, Slavoj Žižek takes the occasion of Marx’s bicentenary for reflecting on the prospects of radical change today. First, it is shown that under Stalinism, Lenin’s works were quoted out of context in an arbitrary way in order to legitimise arbitrary political measures. Marxism thereby became an ideology that justified brutal subjective interventions. Second, this contribution poses the question of the revolutionary subject and democracy today. It stresses the role of both contingency and strategy in revolutions. In political assemblages taking place on public squares, the inert mass of ordinary people is transubstantiated into a politically engaged united force. The basic political problem today is how to best reconfigure democracy. Third, this contribution analyses the “interesting times” we live in. These are times that feature multiple crises, right-wing populism à la Donald Trump and Marine Le Pen, the lower classes’ opposition to immigration, and the refugee crisis. Questions about human rights and their violation and about radical change need to be asked in this context.

  13. Corrosion issues in nuclear industry today

    International Nuclear Information System (INIS)

    Cattant, F.; Crusset, D.; Feron, D.

    2008-01-01

    In the context of global warming, nuclear energy is a carbon-free source of power and so is a meaningful option for energy production without CO 2 emissions. Currently, there are more than 440 commercial nuclear reactors, accounting for about 15% of electric power generation in the world, and there has not been a major accident in over 20 years. The world's fleet of nuclear power plants is, on average, more than 20 years old. Even though the design life of a nuclear power plant is typically 30 or 40 years, it is quite feasible that many nuclear power plants will be able to operate for longer than this. The re-emergence of nuclear power today is founded on the present generation of nuclear reactors meeting the demands of extended service life, ensuring the cost competitiveness of nuclear power and matching enhanced safety requirements. Nuclear power plant engineers should be able to demonstrate such integrity and reliability of their system materials and components as to enable nuclear power plants to operate beyond their initial design life. Effective waste management is another challenge for sustainable nuclear energy today; more precisely, a solution is needed for the management of high-level and long-lived intermediate-level radioactive waste over the very long term. Most nuclear countries are currently gathering the data needed to assess the feasibility of a deep geological waste repository, including the prediction of the behaviour of materials over several thousands of years. The extended service life of nuclear power plants and the need for permanent disposal for nuclear waste are today's key issues in the nuclear industry. We focus here on the major role that corrosion plays in these two factors, and on the French approaches to these two issues. (authors)

    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.)

    1995-01-01

    Since its modest beginning as a single volume in 1914 the ASME Code, or some of its parts, is recognized today in 48 of the United States and all providence's of Canada. The ASME Code today is composed of 25 books including two Code Case books. These books cover the new construction of boilers and pressure vessels and the new construction and In-Service-Inspection of Nuclear Power Plant components. The ASME accredits all manufacturers of boilers and pressure vessels built to the ASME Code. There are approximately 7650 symbol stamps issued throughout the world. Over 23% of the symbol stamps have been issued outside the USA and Canada. The challenge to the ASME Code is to be accepted as the world standard for pressure boundary components. There are activities underway to achieve that goal. The ASME Code is being revised to make it a more friendly document to entities outside of North America. To achieve that end there are specific tasks underway which are described here

    2015-12-01

    Full Text Available The author undertakes an attempt to answer the following question: is Christian philosophy possible today? The question seems to be of great importance due to the fact that what Christians who try to do philosophy usually encounter is bitter criticism which comes to them from two sides at once: that of academy and that of the Church. In short, for academy their philosophy is too Christian, and for the Church it is too academic. Being indebted to the insights of Étienne Gilson and Mieczyslaw A. Krapiec (the original Polish spelling: Mieczysław Albert Krąpiec, pronounced: myechisuaf albert krompyetz, the author comes to the conclusion thatChristian philosophy is possible today only if: 1 it isnot identified with the art of persuasion, as its final end lies in gaining understanding rather than being convincing, 2 itis the work of a Christian, and 3 it has thereal world as its object and metaphysics as its method. ForChristian philosophy—which in essence consists indoing philosophy by Christians in order to get morerational understanding of their religious faith—shouldbe identified with theperfection of the intellect achieved by practicingthe classical philosophy of being.

    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.

    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.

  5. Why preeclampsia still exists?

    Chelbi, Sonia T; Veitia, Reiner A; Vaiman, Daniel

    2013-08-01

    Preeclampsia (PE) is a deadly gestational disease affecting up to 10% of women and specific of the human species. Preeclampsia is clearly multifactorial, but the existence of a genetic basis for this disease is now clearly established by the existence of familial cases, epidemiological studies and known predisposing gene polymorphisms. PE is very common despite the fact that Darwinian pressure should have rapidly eliminated or strongly minimized the frequency of predisposing alleles. Consecutive pregnancies with the same partner decrease the risk and severity of PE. Here, we show that, due to this peculiar feature, preeclampsia predisposing-alleles can be differentially maintained according to the familial structure. Thus, we suggest that an optimal frequency of PE-predisposing alleles in human populations can be achieved as a result of a trade-off between benefits of exogamy, importance for maintaining genetic diversity and increase of the fitness owing to a stable paternal investment.

    Bioethicists disagree over methods, theories, decision-making guides, case analyses and public policies. Thirty years ago, the thinking of many scholars coalesced around a principlist approach to bioethics. That mid-level mode of moral reasoning is now one of many approaches to moral deliberation. Significant variation in contemporary approaches to the study of ethical issues related to medicine, biotechnology and health care raises the question of whether bioethics exists as widely shared method, theory, normative framework or mode of moral reasoning.

    Full Text Available Ancient Azerbaijanian music was found after archelogical excavations. In the first literature The Book of Dede Korkut, then in Nizami's and Fuzuli's literal works a vast of information could be found about the Medieval Age music. The first phase of Azerbaijanian musical history contains arts of bards, laters phases contains classical modes. The researches of Azerbaijanian modes extend to the Medieval Age. The expand of 19th century European music affected Azerbaijanian culture, too. The early years of 20th century is reckoned as a new rising period in Azerbaijanin music. Uzeyir Hacibeyov composed Leyli and Majnun in that period which was the first opera of the East. Meanwhile, several musical high schools, conservatories, symphony orchestras, national instrumental orchestras, and theatres were established. The smphonic music which was established in 1920's had a major development in between 1940 and 1960. In between 1960 and 1980, younger generation, too, participated in artistic activities, alongside the older generation. In 1988-1994 Armenians invaded Karabagh and commited several genocides which some of the most known are called 20 January and Khojaly genocides. In that period, Azerbaijanian composes divided into three stages as 20 January, Karabagh, and Khojaly. Today, Azerbaijanian music is well known all over the world, while being played in lots of festivals in the whole world.

  13. Introduction: The Continued Importance of Smallholders Today

    Directory of Open Access Journals (Sweden)

    Jacqueline M. Vadjunec

    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.

    2010-09-01

    As members of professional organizations such as American Society of Primatologists (ASP) and the International Primatological Society (IPS), primatologists must adhere to a set of nonhuman primate-focused principles outlined in resolutions and policy statements on, for example, the ethical treatment of nonhuman primates. Those of us that work in the field must also address issues such as the protection of primate health in the wild and the conservation of wild primate populations. Moreover, we increasingly find ourselves in complex situations where we must balance human and nonhuman primate needs and interests. The selection of commentary pieces in this edition of the American Journal of Primatology originated from presentations given in the symposium, Field Primatology of Today: Navigating the Ethical Landscape, held at the 32nd Annual Meeting of the American Society of Primatologists (ASP) in September 2009. The goals of that symposium and these resulting commentary pieces are threefold: (1) to revive a discussion of key contemporary ethical issues faced by field primatologists, (2) to highlight the need for centrally placed ethical considerations in various facets of our professional lives, particularly research and teaching, and (3) to consider what a comprehensive ethical code that addresses all of these issues might look like.

    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.

  16. [Poliomyelitis in Landsteiner's time and today].

    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.

    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.

    Supergiant Fast X-ray Transients (SFXTs) are one of the most interesting (and unexpected) results of the INTEGRAL mission. They are a new class of HMXBs displaying short hard X-ray outbursts (duration less tha a day) characterized by fast flares (few hours timescale) and large dinamic range (10E3-10E4). The physical mechanism driving their peculiar behaviour is still unclear and highly debated: some models involve the structure of the supergiant companion donor wind (likely clumpy, in a spherical or non spherical geometry) and the orbital properties (wide separation with eccentric or circular orbit), while others involve the properties of the neutron star compact object and invoke very low magnetic field values (B 1E14 G, magnetars). The picture is still highly unclear from the observational point of view as well: no cyclotron lines have been detected in the spectra, thus the strength of the neutron star magnetic field is unknown. Orbital periods have been measured in only 4 systems, spanning from 3.3 days to 165 days. Even the duty cycle seems to be quite different from source to source. The Energetic X-ray Imaging Survey Telescope (EXIST), with its hard X-ray all-sky survey and large improved limiting sensitivity, will allow us to get a clearer picture of SFXTs. A complete census of their number is essential to enlarge the sample. A long term and continuous as possible X-ray monitoring is crucial to -(1) obtain the duty cycle, -(2 )investigate their unknown orbital properties (separation, orbital period, eccentricity),- (3) to completely cover the whole outburst activity, (4)-to search for cyclotron lines in the high energy spectra. EXIST observations will provide crucial informations to test the different models and shed light on the peculiar behaviour of SFXTs.

    2005-09-01

    Today, you are about as safe in a U.S. hospital as you would be parachuting off a bridge or a building. But it doesn't have to be that way. Right now, some hospitals are making enormous short-term improvements, with no legislation or market reconfiguration and little or no capital investment. Instead of waiting for sweeping changes in market mechanisms, these institutions are taking an operations approach to patient care. In case after detailed case, the article describes how doctors, nurses, technicians, and managers are radically increasing the effectiveness of patient care and dramatically lowering its cost by applying the same capabilities in operations design and improvement that drive the famous Toyota Production System. They are removing ambiguity in the output, responsibilities, connections, and methods of their work processes. These changes-which can be done in the course of an ordinary workday, sometimes in a matter of hours-are designed to make the following crystal clear: Which patient gets which procedure (output); Who does which aspect of the job (responsibility); Exactly which signals are used to indicate that the work should begin (connection); and Precisely how each step is carried out (method). Equally important, managers are being transformed from rescuers who arrive with ready-made solutions into problem solvers who help colleagues learn the experimental method. Thus, these hospitals are breaking free of the work-around culture that routinely obscures the root causes of so many problems, creates so much waste, and leads to so many unnecessary deaths.

    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.

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.

    The radiation hardening studies started in the mid decade -1960-1970. To survive the different military or space radiative environment, a new engineering science borned, to understand the degradation of electronics components. The different solutions to improve the electronic behavior in such environment, have been named radiation hardening of the technologies. Improvement of existing technologies, and qualification method have been widely studied. However, at the other hand, specific technologies was developped : The Silicon On Insulator technologies for CMOS or Bipolar. The HSOI3HD technology (supported by DGA-CEA DAM and LETI with THOMSON TMS) offers today the highest hardening level for the integration density of hundreds of thousand transistors on the same silicon. Full complex systems would be realized on a single die with a technological radiation hardening and no more system hardening

    The current Earth satellite population in LEO for all sizes is relatively well-established by a combination of deterministic and statistical means. At higher altitudes, the population of satellites with diameters of less than 1 m is not well defined. Although a few new sensors might become operational in the near- to mid-term, no major improvement in environment characterization is anticipated during this period. With the increasing deployment of micro- and pico-satellites and with the continued growth of the small debris population, a need exists for better space surveillance to support spacecraft design and operations.

    Electronic publishing is changing the fundamentals of the entire printing/delivery/archive system that has served as the distribution mechanism for scientific research over the last century and a half. The merger-mania of the last 20 years, preprint pools, and publishers' licensing and journals-bundling plans are among the phenomena impacting the scientific information field. Science-Technology-Medical (STM) publishing is experiencing a period of intense consolidation and reorganization. This paper gives an overview of the economic factors fueling these trends, the major STM publishers, and the government regulatory bodies that referee this industry in Europe, Canada, and the USA.

    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 most important discovery in particle physics in recent years was that of the Higgs boson, and much effort is continuing to measure its properties, which agree obstinately with the Standard Model, so far. However, there are many reasons to expect physics beyond the Standard Model, motivated by the stability of the electroweak vacuum, the existence of dark matter and the origin of the visible matter in the Universe, neutrino physics, the hierarchy of mass scales in physics, cosmological inflation and the need for a quantum theory for gravity. Most of these issues are being addressed by the experiments during Run 2 of the LHC, and supersymmetry could help resolve many of them. In addition to the prospects for the LHC, I also review briefly those for direct searches for dark matter and possible future colliders.

    The expectations put in quantum electrodynamics were deceived when first calculations showed that divergencies, due to the pinpoint aspect of the electron, continued to exist. Later, as a consequence of new experimental data and theoretical progress, an empirical method called renormalization was proposed to allow the evaluation of expressions involving infinite terms. The development of this method opened the way to the theory of re-normalizing fields and gave so successful results that it was applied to all fundamental interactions except gravity. This theory allowed the standard model in weak, electromagnetic and strong interactions to be confronted successfully with experimental data during more than 25 years. This article presents the progressive evolution of ideas in the concept of renormalization. (A.C.)

    The disaster in Unit 4 of the nuclear power plant of Chernobyl, now Ukraine, occurred fourteen years ago. Although much has been written about the accident, the public still has no proper yardstick by which to assess realistically the risk involved. This is true not only with respect to nuclear power plants of the type found in Germany and almost anywhere in the western world, but also in relation to non-nuclear disasters, which tend to be accepted by the public much more readily. As far as the number of persons killed or injured is concerned, the scope of the Chernobyl disaster turned out to be smaller than, or at least comparable to, other disasters. This is true even in comparison with other power generation technologies, for instance, accidents in coal mining or dam bursts. Even major railway accidents, airplane crashes, or the large number of people regularly killed in road traffic, are soon forgotten by the media. (orig.) [de

  1. Challenges to nuclear export controls today

    2014-01-01

    Nuclear energy and nuclear proliferation programs are potentially inter-twinned, which is a point to be taken into account when analysing the development of civil nuclear energy, both domestically and as foreign investment. International agreements ensure that the adhering countries fulfil their obligations and do not abuse civil nuclear programs for the production of nuclear weapons. Uranium enrichment is the process currently most focused on in this respect by recent news and recent technological and commercial developments. But also the so-called reactor-based pathway, with extraction of plutonium from spent nuclear fuel by reprocessing remains in the spotlight of inspectors. Two of the main and complementary pillars on which the prevention of such diversion relies, are Strategic Export Control and International Safeguards. Strategic export control is a key barrier against nuclear proliferation. In many countries including the EU, it is set by a legal framework, envisaging implementation, enforcement and prosecution. The goods that can exported only with authorisations are those identified by the international export control regimes; primarily the Nuclear Suppliers Group in the case of nuclear items. It is complemented by nuclear safeguards measures, and especially in the past few years, by the IAEA State Level concept, which looks at the overall country's potential, including its industrial structure to derive conclusions on the absence of undeclared activities. However, the strict control of goods and knowledge is a moving target, since technological developments, globalisation and the intensifying exchange of information via the worldwide web offer increasing opportunities to proliferators to acquire sensitive items and competencies, and create bigger challenges to enforcement, calling for new responses. Research and development programmes must be directed towards supporting the adaptation of current proliferation containment systems to these new

    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.

  4. Deterrence Today Roles, Challenges and Responses

    deterrence in reassuring traditional allies confronting new hostile proliferators. In practice, however, extending deterrence in response to proliferation threats raises a number of difficult questions and will require adaptation of traditional approaches. But in other situations, what role, if any, deterrence - though not necessarily nuclear deterrence - should play is itself an open question. This applies perhaps most to possible efforts by the United States and other countries to bring to bear deterrence or other complementary strategies aimed at shaping a terrorist adversary's strategic calculus to help meet the threat of use of a nuclear weapon or other WMD attack by al- Qaeda and its Jihadist allies. Here, too, new thinking will be required to define and implement such complementary strategies for influencing the calculations of terrorist adversaries. But questions about the applicability - or at least complexities - of deterrence also are reflected in today's expressions of concern that some new nuclear powers may be 'non-deterrable' as well as that an asymmetric balance of stakes is creating a new deterrence equation outside of Europe. Regarding Russia, Moscow no longer is an adversary of the West but nor is it a friend - and moving beyond deterrence to a non-adversarial relationship so far has been more rhetoric than reality. As for China, the U.S. extended nuclear deterrent continues to play a role in helping to avoid a confrontation over Taiwan as well as in reassuring those officials in Asia that are uncertain about the ultimate impact of China's rise. That said, it would be preferable to mute the role of nuclear deterrence in the U.S.-China strategic relationship and, as with Russia, to develop a non-adversarial relationship between the United States and China. From an American perspective, the following essay addresses this new, more complex agenda of the early 21. century. Specifically, it turns first to the challenge of extending

But in other situations, what role, if any, deterrence - though not necessarily nuclear deterrence - should play is itself an open question. This applies perhaps most to possible efforts by the United States and other countries to bring to bear deterrence or other complementary strategies aimed at shaping a terrorist adversary's strategic calculus to help meet the threat of use of a nuclear weapon or other WMD attack by al- Qaeda and its Jihadist allies. Here, too, new thinking will be required to define and implement such complementary strategies for influencing the calculations of terrorist adversaries. But questions about the applicability - or at least complexities - of deterrence also are reflected in today's expressions of concern that some new nuclear powers may be 'non-deterrable' as well as that an asymmetric balance of stakes is creating a new deterrence equation outside of Europe. Regarding Russia, Moscow no longer is an adversary of the West but nor is it a friend - and moving beyond deterrence to a non-adversarial relationship so far has been more rhetoric than reality. As for China, the U.S. extended nuclear deterrent continues to play a role in helping to avoid a confrontation over Taiwan as well as in reassuring those officials in Asia that are uncertain about the ultimate impact of China's rise. That said, it would be preferable to mute the role of nuclear deterrence in the U.S.-China strategic relationship and, as with Russia, to develop a non-adversarial relationship between the United States and China. From an American perspective, the following essay addresses this new, more complex agenda of the early 21. century. Specifically, it turns first to the challenge of extending deterrence to U.S. allies and

  6. The fuel cell yesterday, today and tomorrow

    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.

  8. Batteries at NASA - Today and Beyond

    Science.gov (United States)

    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.

  9. Serbian lexicology today: Current achievements and perspectives

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available At the turn of 21st century Serbian lexicology is under the influence of the Slavic (predominantly Russian and Anglo-Saxon semanticists. Different semantic theories are used in language analyses in Serbian papers. Since the 1970s componential analysis had been a leading theory, but as of the 1990s Serbian lexicology has come under the influence of cognitive linguistics. There are more and more interdisciplinary investigations where linguistics is interwoven with psychology, communicology, and sociology. Often, lexicology is interwoven with other linguistic disciplines, such as syntax, word formation, morphology, stylistics, etc. Recently, some semantic studies have been conducted from the pragmatic viewpoint. Depending on the object of the analysis and the theory chosen, different research methods are used, such as collocational, associative, and additionally, various types of syntactic and semantic approaches are taken. The focus of interest is semantics of words, and less frequent of morphemes or sentences. The future of Serbian lexicology lies in promoting an interdisciplinary approach, and its relation with other linguistic disciplines and other nonlinguistic sciences.

    1990-01-01

    A Radioactive Waste Management Complex (RWMC) was established at the Idaho National Engineering Laboratory (INEL) in 1952 for controlled disposal of radioactive waste generated at the INEL. Between 1954 and 1970 waste characterized by long lived, alpha emitting radionuclides from the Rocky Flats Plant was also buried at this site. Migration of radionuclides and other hazardous substances from the buried Migration of radionuclides and other hazardous substances from the buried waste has recently been detected. A Buried Waste Program (BWP) was established to manage cleanup of the buried waste. This program has four objectives: (1) determine contaminant sources, (2) determine extent of contamination, (3) mitigate migration, and (4) recommend an alternative for long term management of the waste. Activities designed to meet these objectives have been under way since the inception of the program. The regulatory environment governing these activities is evolving. Pursuant to permitting activities under the Resource Conservation and Recovery Act (RCRA), the Department of Energy (DOE) and the Environmental Protection Agency (EPA) entered into a Consent Order Compliance Agreement (COCA) for cleanup of past practice disposal units at the INEL. Subsequent to identification of the RWMC as a release site, cleanup activities proceeded under dual regulatory coverage of RCRA and the Atomic Energy Act. DOE, EPA, and the State of Idaho are negotiating a RCRA/Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Interagency Agreement (IAG) for management of waste disposal sites at the INEL as a result of the November 1989 listing of the INEL on the National Priority List (NPL). Decision making for selection of cleanup technology will be conducted under the CERCLA process supplemented as required to meet the requirements of the National Environmental Policy Act (NEPA). 7 figs

    Postcombustion CO 2 capture is the best suitable capture technology for existing coal power plants. This paper focuses on an emerging technology that involves the separation of CO 2 using the reversible carbonation reaction of CaO to capture CO 2 from the flue gas, and the calcination of CaCO 3 to regenerate the sorbent and produce concentrated CO 2 for storage. We describe the application to this concept to an existing (with today's technology) power plant. The added capture system incorporates a new supercritical steam cycle to take advantage of the large amount of heat coming out from the high temperature capture process (oxyfired combustion of coal is needed in the CaCO 3 calciner). In these conditions, the capture system is able to generate additional power (26.7% efficiency respect to LHV coal input to the calciner after accounting for all the penalties in the overall system), without disturbing the steam cycle of the reference plant (that retains its 44.9 efficiency). A preliminary cost study of the overall system, using well established analogues in the open literature for the main components, yields capture cost around 16 Euro /ton CO 2 avoided and incremental cost of electricity of just over 1 Euro /MW h e

  14. Psychosocial challenges facing physicians of today.

    Science.gov (United States)

    Arnetz, B B

    2001-01-01

    Fundamental changes in the organization, financing, and delivery of health care have added new stressors or opportunities to the medical profession. These new potential stressors are in addition to previously recognized external and internal ones. The work environment of physicians poses both psychosocial, ergonomic, and physico-chemical threats. The psychosocial work environment has, if anything, worsened. Demands at work increase at the same time as influence over one's work and intellectual stimulation from work decrease. In addition, violence and the threat of violence is another major occupational health problem physicians increasingly face. Financial constraint, managed care and consumerism in health care are other factors that fundamentally change the role of physicians. The rapid deployment of new information technologies will also change the role of the physician towards being more of an advisor and information provider. Many of the minor health problems will increasingly be managed by patients themselves and by non-physician professionals and practitioners of complementary medicine. Finally, the economic and social status of physicians are challenged which is reflected in a slower salary increase compared to many other professional groups. The picture painted above may be seen as uniformly gloomy. In reality, that is not the case. There is growing interest in and awareness of the importance of the psychosocial work environment for the delivery of high quality care. Physicians under stress are more likely to treat patients poorly, both medically and psychologically. They are also more prone to make errors of judgment. Studies where physicians' work environment in entire hospitals has been assessed, results fed-back, and physicians and management have worked with focused improvement processes, have demonstrated measurable improvements in the ratings of the psychosocial work environment. However, it becomes clear from such studies that quality of the

    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.

    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.

  1. Sustainable vehicle fuels - Do they exist?

    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

Clearly, this way of thinking is a piece of the continuous improvement of nuclear technology, several of them being today already taken into account in the last existing plants, such as Rokkasho in Japan. When continuing this effort in the next decade(s), when fully benefiting from the experience collected in the decommissioning programs, our goal is to be able to propose a new kind of 'eco-conception' of treatment plants, for the next generation to come.

    1983-01-01

    A complete census of all the biogas plants operating or under construction today in Italy has been carried out. This shows that more than 60 full-scale plants treating animal wastes are today in operation. Then there are several pilot and experimental plants built by the numerous Italian firms that design and sell anaerobic digesters and by various research groups of the universities and of state agencies. Some plants, among which some large-size ones, have been self-built by the farmers. The great amount of collected data allowed us to focus the main technological choices regarding materials, mixing and heating systems, technological cycles and to confront them with the performance of the plants and with the principal technical issues and the problems of management that can be found on large scale plants. Then the analysis of daily biogas production allowed us to determine real parameters of specific production for various kinds of animal wastes and animal farms. Other interesting data concern the main technological means used to transform the biogas into energy: in Italy, for the presence of Flat Industries that produce the TOTEM, the prevalent choice is toward cogeneration of electricity and heat. Anyway there are interesting examples of utilization of biogas for drying forages, for steam generation in cheese factories, and compressed, as a fuel for farm tractors and cars. A complete photographic documentation of all the plants enclosed in the census is also available. 3 refs., 1 fig., 23 tabs.

    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.

  18. Opening speech: nuclear power today - the situation in germany

    International Nuclear Information System (INIS)

    Gueldner, R.

    2005-01-01

    Nuclear power is experiencing an upswing worldwide. High prices of conventional fuels, discussions about the long-term continuity of supply, rising energy requirements, and the search for efficient ways of protecting the climate have moved nuclear power back into focus in a positive way. This is also true for Germany. In this country, nuclear power has gone through twelve very successful months since the 2004 Nuclear Technology Conference in Duesseldorf, as is borne out by the performance of all nuclear power plants in Germany. A change of mood towards a positive view of nuclear power is taking place in Germany. It is also seen, however, that the ''problem'' of final storage, which has been solved technically, is in urgent need of a political solution. German know-how in nuclear technology enjoys a high reputation internationally. For manufacturers and the associated supplier industries, this means excellent market opportunities, also for future projects, in view of worldwide demand. Various nuclear projects have progressed at long last: The Heinz Meier-Leibnitz research reactor (FRM-II) has been commissioned; the final stage of expansion of the Urenco uranium enrichment plant in Gronau has been approved; the license for a capacity increase in the ANF fuel fabrication plant in Lingen has been granted. Nuclear power is enjoying a high reputation also in the European Union. Major expansion plans exist in Asia, while increases in power and performance as well as life extensions can be observed in the United States. The world needs a sustainable energy mix - with nuclear power. (orig.)

  19. Equipping tomorrow's doctors for the patients of today.

    2014-07-01

    As the proportion of older patients with frailty presenting to health services increases, so does the need for doctors to be adequately trained to meet their needs. The presentations seen in such patients, the evidence-based models of care and skillsets required to deliver them are different than for younger patient groups-so specific training is required. Several research programmes have used detailed and explicit methods to establish evidence-based expert-validated curricula outlining learning outcomes for undergraduates in geriatric medicine-there is now broad-consensus on what newly qualified doctors need to know. There are, despite this, shortcomings in the teaching of undergraduates about geriatric medicine. National and international surveys from the UK, EU, USA, Canada, Austria and the Netherlands have all shown shortcomings in the content and amount of undergraduate teaching. Mechanisms to improve this situation, aside from specifying curricula, include developing academic departments and professorships in geriatric medicine, providing grants to develop teaching in geriatric medicine and developing novel teaching interventions to make the best of existing resources. Under the last of these headings, innovations have been shown to improve outcomes by: using technology to ensure the most effective allocation of teaching time and resources; using inter-professional education as a means of improving attitudes towards care of older patients; focusing teaching specifically on attitudes towards older patients and those who work with them; and trying to engage patients in teaching. Research areas going forward include how to incentivise medical schools to deliver specified curricula, how to choose from an ever-expanding array of teaching technologies, how to implement interprofessional education in a sustainable way and how to design teaching interventions using a qualitative understanding of attitudes towards older patients and the teams that care for them.

  20. 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

    Backherms, J.

    1980-01-01

    On the issue of protecting continued economic existence according to Sect. 18 of the Atomic Energy Law, a difference is made between changes occurring in the environment of the plant, in the existing knowledge in science and technology, and changes occurring in the safety philosophy held by the authorities. In case of conditions being subsequently imposed because of a change in the existing knowledge in science and technology, the liability of the authorities to pay compensation is ruled out according to Sect. 18, para. 2 No. 3 of the Atomic Energy Law. The difference made between a change in the safety philosophy held by the authorities and a change in the existing knowledge in science and technology seems to be obvious. In the first case it is a matter of changing the legal evaluation of unchanged technological findings, in the legal evaluation, however, the licence granted has to have a lasting effect on principle.

    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) [de

  6. [Health care in today's Western Belarus in the inter-war period (1921-1939)].

    Science.gov (United States)

    Tiszczenko, E M

    2001-01-01

    During the inter-war period, today's Western Belarus, which under the Treaty of Riga constituted part of the Second Polish Republic, stood out for its higher morbidity in various disease categories than other regions of the country. Heightened threats of epidemics prevailed in that area, and typhoid fever, trachoma, tuberculois and venereal disease were serious health problems. Specific features of the health care of today's Western Belarus could be observed that set it apart from both that of Eastern Belarus forming a part of the Soviet Union as well as from the central and western provinces of Poland. Compared with Eastern Belarus, there was a lack of health services, including anti-tuberculosis, anti-venereal and paediatric dispensaries, or they were in the process of being created. But physicians' self-government bodies functioned, as did out-patient care with dispensary-like elements and health care provided by local health centres. There also existed the institution of full-time family doctors within the insured health-care system - something lacking in Eastern Belarus. As in other voivodships (provinces) of the Second Republic, there existed multi-sector health care: state, local, insurance-based and private. The Western Belarus had Poland's smallest number of physicians, new hospital beds and pharmacies. On the other hand, today's Western Belarus stands out by virtue of maintaining field-medicine traditions. To this day, assistant medical officers provide health care to the rural population - an arrangement not typical of the central and western provinces fo pre-war Poland.

    Morgan and colleagues put forth a call to action for the transformation of the Canadian healthcare system through the adoption of a national chronic disease prevention and management (CDPM) strategy. They offer examples of best practices and national solutions including investment in clinical information technologies to help support improved care and outcomes. Although we acknowledge that the authors propose CDPM solutions that are headed in the right direction, more rapid deployment of solutions that harness the potential of advanced collaborative technologies is required. We provide examples of how technologies that exist today can help to accelerate the achievement of some key CDPM objectives.

    If the world runs on energy, the energy industry runs on finance. Supplying the industry's huge appetite for funds -on the scale and in the form required - has always posed a major challenge to the international banking community. But in some respects that challenge is greater today than it has ever been, not only because of the industry's escalating requirements but also because of the way bank's attitudes have been changing in the recent past. One reason for this is the rapidly evolving scene within the energy business in response to the harsher competitive conditions and the greater uncertainties of tomorrow. However, the other major factor is that banking itself has been undergoing significant change as a result of severe pressures and constraints, both internal and external. Some of the key global trends and issues affecting energy financing in today's world are considered here. (author)

This increase results primarily because standard setters believe asset and liability measures that reflect current economic conditions and up-to-date expectations of the future will result in more useful information for making economic decisions, which is the objective of financial reporting. This is why sta...

  6. "Children are from heaven" or how today children respect adults

    Directory of Open Access Journals (Sweden)

    2007-06-01

    Full Text Available The starting point of the text is a returning to the patriarchal, which is not simply the one that we are witnessing today, in the time of so-called postmodern, postpatriarchal society in its (until now last form. It is a matter of returning to rules, of which the basic premise is that adults are subjects (transcendences, freedoms, activities and children are subjects that are objects for adults (imanences, non-freedoms, pasivities, but which notwithstanding differ from the oldfashioned rules from the past. We attempted to explain this returning, following the example of rules offered by the book Children Are From Heaven – a selfhelp book, published at the end of the nineties of the 20th century, which immediately became the world's bestseller. In addition, our aim was to answer the following questions: What has happened with rules of civilization and good manners, regulating the relations between children and adults today? How have they changed and what has happened with children's or adults's relation to these rules or their performings? How has this relation changed? Considering the mentioned basic premise which implies that children respect adults, we also tried to answer the question: What has happened with the respect, or, how do children respect adults today? Disscussion is presented in the framework of lacanian psychoanalysis.

  8. Technology Solutions Case Study: Selecting Ventilation Systems for Existing Homes

    Energy Technology Data Exchange (ETDEWEB)

    None

    2014-12-01

    In multifamily buildings, particularly in the Northeast, exhaust ventilation strategies are the norm as a means of meeting both local exhaust and whole-unit mechanical ventilation rates. The issue of where the "fresh" air is coming from is gaining significance as air-tightness standards for enclosures become more stringent, and the normal leakage paths through the building envelope disappear. Researchers from the Consortium for Advanced Residential Buildings (CARB) found that the majority of high performance, new construction, multifamily housing in the Northeast use one of four general strategies for ventilation: continuous exhaust only with no designated supply or make-up air source, continuous exhaust with ducted make-up air to apartments, continuous exhaust with supply through a make-up air device integral to the unit HVAC, and continuous exhaust with supply through a passive inlet device, such as a trickle vent. Insufficient information is available to designers on how these various systems are best applied. In this project, the CARB team evaluated the four different strategies for providing make-up air to multifamily residential buildings and developed guidelines to help contractors and building owners choose the best ventilation systems.

  9. Improvements of existing early warning system in Croatia

    2000-01-01

    The gamma radiation early warning system in Croatia was established in 1993. The first configuration contained 3 measuring stations connected to the monitoring center and up today the system is expanded with 5 additional locations. Each location is equipped with the MFM202 gamma-monitor and additional equipment that is not unique for all locations. This difference in remote equipment configuration caused by different communication medium used, is the reason to improve existing system trough equipment unification introducing PLC unit in the standard configuration. Such configuration enables additional functions such as automatic alerting and collecting meteorological data. (author)

  10. Quantum logics with existence property

    International Nuclear Information System (INIS)

    Schindler, C.

    1991-01-01

    A quantum logic (σ-orthocomplete orthomodular poset L with a convex, unital, and separating set Δ of states) is said to have the existence property if the expectation functionals on lin(Δ) associated with the bounded observables of L form a vector space. Classical quantum logics as well as the Hilbert space logics of traditional quantum mechanics have this property. The author shows that, if a quantum logic satisfies certain conditions in addition to having property E, then the number of its blocks (maximal classical subsystems) must either be one (classical logics) or uncountable (as in Hilbert space logics)

  11. Beyond the Drake Equation: On the Probability of the Nature of Extraterrestrial Life Forms in Our Galaxy Today

    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.

    2008-01-01

    The aim of this study is to determine which health resorts existed in 1897 in Istria, Carinthia and Styria region, how many of them are still in use today and how the spas and their offer were represented in the past and how they are represented today. The study is based on the textbook Balneotherapie II (Bibliothek des Arztes 1900) by prof. dr. Julius Glax. The second source of our study is based on the currently available presentation of the health resorts from the internet. The textbook Balneotherapie was intended for the post graduate education of physicians and general practitioners, so they could advise the patient on further treatment in an appropriate health resort. In the chapter Balneographie the author represented 1200 health resorts all over the world. From the book we have chosen the following regions: Istria, Carinthia and Styria which used to be three parts of the Austro-Hungarian Empire. Today they are divided in to three neighboring states: Croatia (Istria), Slovenia (Istria, Carinthia, Styria) and Austria (Carinthia, Styria). Within these regions Glax presented 22 health resorts, 19 of them are still working today. Barbarabad/Barbara bath (Carinthia, Austria) does not exist either as a resort or as a city. Rimske toplice (Römerbad/Roman baths) and Rimski vrelec (Römerquelle/ Roman springs) in Styria region do not function as health resorts any more. Nowadays we make a difference between spa and health resorts. Spa resorts offer numerous forms of recreation for better well being. Health resorts offer health services, as well as neglected, but various forms of alternative treatments and recreation. Each spa and health resort is represented in brochures and on the World Wide Web individually. Tradition is usually not mentioned, it is neglected but the exception is Opatija (Abbazia) which past is usually presented in the brochures. The museum of medical tourism was opened in November 2007 in Opatija where you can admire the development of Opatija

  13. Today's university students and their need to connect

    2014-10-01

    Full Text Available Higher education is rapidly changing and university instructors are presented with new types of students for whom technology is a significant influence. They perceive technology as a way of life and express a need to feel connected at all times. With increasingly diverse university classroom, technology integration is both a challenge and an opportunity. Supportive communication is important in the promotion of relationships and essential in a university classroom.  A convenience sample of 390 students was surveyed to investigate the perceived influences of technology on relationships, including preferences, usage and time with technologies. Results indicated that technology makes communication easier, allows students to stay in touch with more people, and have relationships that would otherwise not be possible.  Implications of this study suggest positive influences of technology on academic work, performance and maintenance of relationships, but disadvantages such as increased stress, addictive feelings toward technologies, and increased misunderstandings in relationships and conflict.

    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.

  17. Technology in the policy process - controlling nuclear power

    International Nuclear Information System (INIS)

    Collingridge, D.

    1983-01-01

    The discussion in this book is built around nuclear power. The technology of nuclear power is shown to have features which make it inflexible in the sense that, once built, it is difficult and expensive to control. If inflexible technology is to be avoided, it is crucially important to be able to identify this failing at an early stage in the technology's development, before it has acquired an immunity to political control. Again, this problem is approached through the example of nuclear power, in particular the breeder reactor. The breeder is shown to be even less flexible than today's nuclear technology, because it will have higher capital costs, be of greater capital intensity, longer lead time, larger unit size, and will require more infrastructure for its operation. If this is developed, the breeder will be even less open to political control than the nuclear plant of the present. To put it another way, its planning will be even more open to errors and whatever errors are made will be even more costly than for existing nuclear technology. It is therefore even less of a socially and economically acceptable technology than today's nuclear power. (author)

    The results of investigation of cold nuclear fusion on palladium are given both for electrolysis of heavy water D 2 O and mixture D 2 O + H 2 O) (1:1) and for palladium saturation with gaseous deuterium. The possibility of existance of this phenomenon was examined by detection of neutrons and gamma quanta from reactions: d + d → 3 He + n + 3.27 MeV, p + d → 3 He + γ + 5.5 MeV. Besides these reactions were identified by measuring the characteristic X radiation of palladium due to effect of charged products 3 He, p, t. The upper limits of the intensities of hypothetical sources of neutrons and gamma quanta at the 95% confidence level were obtained to be Q n ≤ 2x10 -2 n/sxcm 3 Pd, Q γ ≤ 2x10 -3 γ/sxcm 3 Pd. 2 refs.; 4 figs.; 2 tabs

  19. Straightening: existence, uniqueness and stability

    Destrade, M.; Ogden, R. W.; Sgura, I.; Vergori, L.

    2014-01-01

    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.

    International Nuclear Information System (INIS)

    Seab, C.G.; Hollenbach, D.J.; Mckee, C.F.; Tielens, A.G.G.M.

    1986-01-01

    There exists a discrepancy between calculated destruction rates of grains in the interstellar medium and postulated sources of new grains. This problem was examined by modelling the global life cycle of grains in the galaxy. The model includes: grain destruction due to supernovae shock waves; grain injection from cool stars, planetary nebulae, star formation, novae, and supernovae; grain growth by accretion in dark clouds; and a mixing scheme between phases of the interstellar medium. Grain growth in molecular clouds is considered as a mechanism or increasing the formation rate. To decrease the shock destruction rate, several new physical processes, such as partial vaporization effects in grain-grain collisions, breakdown of the small Larmor radius approximation for betatron acceleration, and relaxation of the steady-state shock assumption are included

    Full Text Available South African managers today find themselves squeezed between juxtapositions, such as international competition and simultaneous skill development programmes to combat illiteracy. A second example is high unemployment and the concurrent shortage of IT specialists. Affirmative action has led to troublesome labour relations. HIV/AIDS has an enormous impact on business and must be managed. South African managers need to change their managerial approaches to cope with the increasing demands of this country. Managers must be aware of the realities facing them and know how to turn them into potential growth opportunities for their organisations and South Africa as a country.

  8. Darwinism determines technological survivors

    International Nuclear Information System (INIS)

    Bevc, F.; Harkness, S.

    1996-01-01

    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

    Full Text Available Years ago, exploration was done through surface observations and „divining rods“ – now, it is done by satellites, microprocessors, remote sensing, and supercomputers. In the 1970´ s, the exploration success rate was 14 percent, today, it is nearly 29 percent. Not so long ago, three – dimension (3D seismic diagnostic techniques helped recover 25-50 percent of the oil in place – now, 4D seismic helps recover up to 70 percent of the oil in place. 3D and 4D seismic and earth imaging systems also help in understanding the subsurface flow of other fluids, such as groundwater and pollutants.Seismic surveys – a technique in which sound waves are bounced off underground rock struktures to reveal possible oil and gas bearing formation – are now standard fare for the modern petroleum industry. But today’s seismic methods are best at locating „structural traps“ where faults or folds in the underground rock have created zones where oil can become trapped.

    Virtual Observatory (VO) is a collection of interoperating data archives and software tools. Taking advantages of the latest information technologies, it aims to provide a data-intensively online research environment for astronomers all around the world. A large number of high-qualified astronomical software packages and libraries are powerful and easy of use, and have been widely used by astronomers for many years. Integrating those toolkits into the VO system is a necessary and important task for the VO developers. VO architecture greatly depends on Grid and Web services, consequently the general VO integration route is "Java Ready - Grid Ready - VO Ready". In the paper, we discuss the importance of VO integration for existing toolkits and discuss the possible solutions. We introduce two efforts in the field from China-VO project, "gImageMagick" and "Galactic abundance gradients statistical research under grid environment". We also discuss what additional work should be done to convert Grid service to VO service.

    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

    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. As additional goal the study gives practical introduction in the instrumentation and to the energy label for elevators. (authors)

    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

  5. Summary of existing uncertainty methods

    A summary of existing and most used uncertainty methods is presented, and the main features are compared. One of these methods is the order statistics method based on Wilks' formula. It is applied in safety research as well as in licensing. This method has been first proposed by GRS for use in deterministic safety analysis, and is now used by many organisations world-wide. Its advantage is that the number of potential uncertain input and output parameters is not limited to a small number. Such a limitation was necessary for the first demonstration of the Code Scaling Applicability Uncertainty Method (CSAU) by the United States Regulatory Commission (USNRC). They did not apply Wilks' formula in their statistical method propagating input uncertainties to obtain the uncertainty of a single output variable, like peak cladding temperature. A Phenomena Identification and Ranking Table (PIRT) was set up in order to limit the number of uncertain input parameters, and consequently, the number of calculations to be performed. Another purpose of such a PIRT process is to identify the most important physical phenomena which a computer code should be suitable to calculate. The validation of the code should be focused on the identified phenomena. Response surfaces are used in some applications replacing the computer code for performing a high number of calculations. The second well known uncertainty method is the Uncertainty Methodology Based on Accuracy Extrapolation (UMAE) and the follow-up method 'Code with the Capability of Internal Assessment of Uncertainty (CIAU)' developed by the University Pisa. Unlike the statistical approaches, the CIAU does compare experimental data with calculation results. It does not consider uncertain input parameters. Therefore, the CIAU is highly dependent on the experimental database. The accuracy gained from the comparison between experimental data and calculated results are extrapolated to obtain the uncertainty of the system code predictions

    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

    Alberta's industrial project scene from 1981 to 2000 was presented in this power point presentation with particular focus on proposed bitumen recovery projects and heavy oil project challenges. A graph depicting GTG world orders by region (Americas, Asia and Europe) showed that U.S. market continues to drive global growth. Major industrial projects in Alberta were highlighted and employment requirements by sector were outlined. In addition, mitigation measures that are needed to successfully deal with the unique challenges of today's market were described. It was noted that in recent years lower capital expenditure by the industry in general has resulted in corporate downsizing or mergers which in turn have resulted in lower technical and operational knowledge. Some of the current challenges facing the industry are new demands for water treatment expertise and an aging workforce. It was concluded that effective mitigation will require a disciplined approach within a flexible framework.1 tab., 7 figs

    The Purex process very quickly and very widely supplanted the other concepts considered for nuclear fuel reprocessing after the presentation made at the Geneva Conference in 1955. The selectivity and radiolytic stability of tributylphosphate (T.B.P) clearly appeared to augur an extremely attractive process for completing the separation of valuable elements in the irradiated fuel. The concept has confirmed its validity, and subsequently its ability to adapt to changing requirements or constraints. Its industrial viability is in fact unquestioned today: Purex process is the basis of all the reprocessing plants in operation or planned throughout the world, and recent commissioning of the UP3 plant in France, in remarkable conditions, attests to such a level of maturity that one is tempted to ask the question: ``What remains to be proved, discovered or improved in the core of the Purex process?``.

    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.

    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.

    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.

    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.)

    When physicians implant cardiac rhythm management devices, they establish a long-term relationship with those devices and with the manufacturers of those devices. The therapeutic value that each device will provide to its patient is enhanced throughout the life of the device by the services that the manufacturer provides. Services are provided prior to, during and long after implantation. Services include physician and allied health professional training, quality assurance programs, therapy outreach initiatives, on site technical support during device implantation and follow-up, technical service expertise and customer service support. The costs of these services are substantial. When assessed on a per device basis, the service costs may actually exceed the costs of manufacture. Further, the costs of these services are rising. Over the past five years, the number of implanted cardiac rhythm management devices has doubled. Industry field forces have tripled in size. Clearly, industry is dedicated to providing service as a critical element in achieving excellent patient outcomes.

  5. 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.

Educators should know this relationship because technology begins to affect teaching…

  9. Virtual existence in contemporary Serbian novel

    Directory of Open Access Journals (Sweden)

    Gordić-Petković Vladislava S.

    2017-01-01

    Full Text Available The paper sets out to explore the perspectives and strategies of virtual existence in contemporary Serbian novel in order to illustrate radical changes in the concept of reality and writers' concern with the fidelity to experience. A new surge of the so-called digital realism emerges simultaneously with the increase of awareness that the line between our digital selves and our real-world selves has become blurred and difficult to explain, while new technologies are required to go beyond what our human senses can encompass and deliver. The fictional realism of the digital age will also commit itself to young or middle-aged individuals that passionately attempt to define their aims and objectives so that they could fit into a newly constructed and acquired concept of reality. This is the case with the protagonists in the novels by Ivančica Đerić, Tamara Jecić and Aleksandar Ilić, all of them questioning both their offline and online identities. Their everyday life in a postmillennial world includes many intersecting empirical and virtual realities: love, career and sex take place in a dimension which ignores geography and physical distance and ultimately alters the concepts of time and space, as well the concepts of privacy and intimacy. The paper intends to examine the ways new digital technologies contribute to representations of reality in the novels of both accomplished and aspiring authors whose novels deal with ways of life amid social networks. The novels we analyzed show that the distinction between the virtual and the real world narrows, as the narratives range from intimate confession in letters and journals to tweets, notes and statuses, introducing verbal and structural experimental practices which involve shifting points of view.

    2017-01-01

    Why are so many of today's digital assistants presented as feminine? How does this relate to the history of workplace technologies and women's participation in the labour force? This article seeks to answer these questions, arguing that some elements of "women's work" are now being outsourced to machines – with interesting implications for our understandings of gender.

  11. Teenage Mothers Today: What We Know and How It Matters

    Science.gov (United States)

    Mollborn, Stefanie

    2016-01-01

    Over the past two decades, births to U.S. teenagers have fallen and no longer follow overall fertility patterns. Yet the unique challenges faced by teenage mothers and their families justify continued research. Across disciplines, newer work has furthered our understanding of teenage motherhood today. In this article, I highlight four areas of progress: processes of selection into teenage motherhood, the broader consequences of teenage childbearing beyond the socioeconomic realm, heterogeneity of effects, and the application of life course principles. Emerging societal trends such as complex family structures, a stalled recovery from the recession for families of low socioeconomic status, and a rapidly evolving political environment for reproductive health care continue to challenge the lives of teenage mothers. Given that the consequences for teenagers of becoming mothers may change, continued research is needed. Shifts in policy to favor supporting teenage mothers and addressing the causes of both teenage pregnancy and social disadvantage may help improve the lives of these mothers and their families.

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

    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.

  14. Financial Management in Children: Today Need, Tomorrow Necessity

    Full Text Available Nearly 80% of young people today will never be able to retire. Why? Because they lack the personal finance training that leads to long-term planning and future security. Connecting the dots between kids and money management skills prepares them for the financial realities the world will face over the next century. 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. Cardiological-interventional therapy of coronary artery disease today

    International Nuclear Information System (INIS)

    Reynen, K.; Henssge, R.

    1999-01-01

    The current importance of the interventional therapy of coronary artery disease may be deduced from the exponential increase in procedures performed in Germany in the last decade - at least 125,840 in 1996. Today, by improved catheter and balloon materials as well as by growing experience of the cardiologists, even complex lesions may be treated. Limitations of balloon angioplasty include acute vessel closure and restenosis - newer angioplasty devices like directional or rotational atherectomy or excimer-laser angioplasty did not overcome these limitations; only by coronary stenting, acute vessel closure could be managed and the likelihood of restenosis - at least in particular groups of patients - could be reduced. For a few years, intracoronary brachytherapy of the segments dilated with beta- or gamma-emitters has been seeking to reduce restenosis rate; the department of cardiology of the Dresden Cardiovascular Institute is participating in such a multicentre study using the beta-emitter 188 renium. Further main topics of our department represent primary angioplasty in patients with acute myocardial infarction and invasive diagnostic or interventional procedures by the transradial approach.

    Lia-Alexandra BALTADOR

    2016-12-01

    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.

  17. 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.

  18. Analytical difficulties facing today's regulatory laboratories: issues in method validation.

    Science.gov (United States)

    MacNeil, James D

    2012-08-01

    The challenges facing analytical laboratories today are not unlike those faced in the past, although both the degree of complexity and the rate of change have increased. Challenges such as development and maintenance of expertise, maintenance and up-dating of equipment, and the introduction of new test methods have always been familiar themes for analytical laboratories, but international guidelines for laboratories involved in the import and export testing of food require management of such changes in a context which includes quality assurance, accreditation, and method validation considerations. Decisions as to when a change in a method requires re-validation of the method or on the design of a validation scheme for a complex multi-residue method require a well-considered strategy, based on a current knowledge of international guidance documents and regulatory requirements, as well the laboratory's quality system requirements. Validation demonstrates that a method is 'fit for purpose', so the requirement for validation should be assessed in terms of the intended use of a method and, in the case of change or modification of a method, whether that change or modification may affect a previously validated performance characteristic. In general, method validation involves method scope, calibration-related parameters, method precision, and recovery. Any method change which may affect method scope or any performance parameters will require re-validation. Some typical situations involving change in methods are discussed and a decision process proposed for selection of appropriate validation measures. © 2012 John Wiley & Sons, Ltd.

  19. 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.

  20. What are today's choices for PWRs water chemistry?

    International Nuclear Information System (INIS)

    Berge, P.

    1998-01-01

    Water chemistry has always been, from the very beginning of operation of power Pressurized Water Reactors (PWRs), an important factor in determining the integrity of many reactor components. For both the primary and secondary coolant circuits, the parameters to control the quality of the chemistry have been subject to changes in time. These changes were dictated mainly by corrosion problems which required an adjustment of the chemistry, before any modification could be made in the design or the selection of materials for the subsequently built reactors or replacement components. The situation today, despite 40 years of experience, still leaves open different options for the specifications of the chemistry of the circuits. These options are sometimes due to differences in design or materials of the circuits, but more often, to the perception by the plant chemists, of the role of the chemistry on the different phenomena which could affect the operation of their plant. Paul Cohen, who was well known in the nuclear industry for the early development of the chemistry in PWRs in the USA, used to say, 'if the head chemist has changed in a plant, the chemistry will change'. The purpose of this lecture is to discuss some of the options which are offered to the chemist in compliance with the basic principles of the chemistry guidelines. (J.P.N.)

    New developments in visual communication technologies, and the increasingly digital nature of the industry infrastructure as a whole, are converging to enable new visual environments with an enhanced visual component in interaction, entertainment, and education. New applications and markets can be created, but this depends on the ability of the visual communications industry to provide market solutions that are cost effective and user friendly. Industry-wide cooperation in the development of integrated, open architecture applications enables the realization of such market solutions. This paper describes the work being done by Texas Instruments, in the development of its Digital Light ProcessingTM technology, to support the development of new visual communications technologies and applications.

    Leadership by state and local governments is critical to unlock national energy efficiency opportunities and deliver the benefits of efficiency to all Americans. But related to building energy efficiency, what will it mean to be a public sector leader over the next several years? What are the energy efficiency solutions that cities, counties, and states are implementing today that will make their communities more affordable, livable, healthy, and economically competitive? The SEE Action Network 2020 Leadership Agenda for Existing Commercial and Multifamily Buildings establishes a benchmark for state and local government leadership on improving the energy efficiency of buildings and seeks two-way collaboration among state, local, and federal officials. It defines a suite of innovative, yet practical policies and programs for policymakers to consider implementing by 2020, focusing on six important areas.

    Technology alone will not solve our many environmental, economic and military problems. The search for peace and security must be based on a concept of international security that extends beyond the bounds of military concerns and into the realm of environmental and economic matters. In our efforts to understand how science and technology fit within this security context, we should not look simply at emerging technologies, even those that are sustainable and stabilizing, as being the principal candidates for drastic improvements in peace and security on our planet. One must keep in mind that security for as many as one fourth to one half of the world's inhabitants would be revolutionized if they had access to some of the most basic existing technologies of our times. Equitable access to resources and technology is an age-old problem. Today it must be faced on a global basis. It demands creating a new world economic order that combines the best that the capitalist and socialist economies can offer. We must declare today that a secure global society cannot exist which is half in slavery to poverty and deprived of opportunity, and half free to develop its potential and achieve its dreams

    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.

    Colletti, Jerome A; Fiss, Mary S

    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.

  18. DEVELOPMENT OF MIGRATION POTENTIAL IN HUNGARY FROM 2000 UNTIL TODAY

    2018-03-01

    Full Text Available Hearing the words “international migration”, two things might come to our mind. One of them is the emigration process and the other is the wave of refugees. In our study, we examined the changes of the number of employees emigrating from Hungary from 2000 until today. Nowadays, the examination of the migration potential is an important topic in Hungary, since the rate of Hungarian emigrants started to grow after 2006 and the rate of growth became even faster after 2010. The reason of the acceleration was the opening of the Austrian and German labour market. The actuality of the topic is based on the fact that international emigration merges the labour market’s processes, influences the given country’s employment level, moreover it has an influencing role on the rate of wages. Emigration from a given state has several reasons: natural disasters, war, marginalization, economic reasons, etc. In our study, we examine emigration caused by economic reasons. We have to take into consideration that measuring emigration processes is a difficult task, due to the lack of data. The reason of the deficiency is that those who leave the country, often forget to report their leaving. From 1 March 2013, only the permanent foreign settlement should be reported towards the administration (District Office, Consulate. Earlier, temporary (more than 3 months settlement was also obligatory to be reported. Many of the leaving Hungarians do not report their leaving, however working abroad for more than 3 months should be reported towards social insurance organizations and tax authorities. I would like to emphasise that my migration potential presentation does not show a direct correlation with the actual migration. However, this study might show the expected movement rates and the composition of emigrants.

    2014-12-01

    Today, the German-lead Cosmic Dust Analyser (CDA) is operated continuously for 10 years in orbit around Saturn. The first discovery of CDA related to Saturn was the measurement of nanometer sized dust particles ejected by to interplanetary space with speeds higher than 100 km/s. Their origin and composition was analysed and and their dynamical studies showed a strong link to the conditions of the solar wind plasma flow. A recent surprising result was, that stream particles stem from the interior of Enceladus. Since 2004 CDA measured millions of dust impacts characterizing the dust environment of Saturn. The instrument showed strong evidence for ice geysers located at the south pole of Saturn's moon Enceladus in 2005. Later, a detailed compositional analysis of the salt-rich water ice grains in Saturn's E ring system lead to the discovery of liquid water below the icy crust connected to an ocean at depth feeding the icy jets. CDA was even capable to derive a spatially resolved compositional profile of the plume during close Enceladus flybys. A determination of the dust-magnetosphere interaction and the discovery of the extended E ring allowed the definition of a dynamical dust model of Saturn's E ring describing the observed properties. The measured dust density profiles in the dense E ring revealed geometric asymmetries.In the final three years CDA performs exogenous and interstellar dust campaigns, studies of the composition and origin of Saturn's main rings by unique ring ejecta measurements, long-duration nano-dust stream observations, high-resolution maps of small moon orbit crossings, studies of the dust cloud around Dione and studies of the E-ring interaction with the large moon Titan.

    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.

    Never before has the opportunity for terrestrial optical wireless communications links been so great. The high data rates attainable, up to OC-24, make it a very attractive and cost effective alternative to traditional fiber optic and microwave links. With today's demand for interactive multimedia-based applications, such as video conferencing and telemedicine, optical wireless products are the only ones that can provide the needed bandwidth in situations when it is too costly or impossible to install fiber optic cable. Recent developments in laser and optics technologies, in addition to auto beam tracking, permit transmission units to achieve excellent performance rates in all weather conditions.

  6. Do Elementary Particles Have an Objective Existence?

    OpenAIRE

    Nissenson, Bilha

    2007-01-01

    The formulation of quantum theory does not comply with the notion of objective existence of elementary particles. Objective existence independent of observation implies the distinguishability of elementary particles. In other words: If elementary particles have an objective existence independent of observations, then they are distinguishable. Or if elementary particles are indistinguishable then matter cannot have existence independent of our observation. This paper presents a simple deductio...

    Full Text Available Science plays an important role of development of national economies of developed countries. Postindustrial society, society of knowledge is a society where scientific discoveries, scientific research results ensure economic growth, economic stability, economic exuberance. In such a society not goods, not movable and real property and not natural resources, including power, put together the main society wealth, but scientific discoveries, new knowledge. Countries, which gain primary income from scientific discoveries and high technologies, are prosperous in the modern world. The purpose of study. A solution of science problems in the modern world should become an important direction of a state’s attention to providing national security. Weakening of academic and technological as well as technological potential of the country, research reduction, mass closure of research institutes and centres, several-ford reduction in the volume of funding of science, outflow of specialists and intellectual property abroad for the last three years menace Ukraine with a loss of advanced positions in the world, degradation of knowledge-intensive industries, strengthening of external technological dependence and undermining of its defensive capacity. Such a situation predetermined the topic of our research, its main purpose – identification of problems of science financing and determination of ways to solve them. Research methods. When writing the article, a set of methods and approaches was used that allowed realizing a conceptual unity of the research. Dialectical, system, structural methods are used for the analysis of financing of the science advancement in Ukraine, existent problems of the science financing are generalized with the help of comparative and factorial methods; ways for improving financing of the science advancement are determined by using methods of scientific abstraction, synthesis, functional analysis.

  15. Does Glocal Political Power Already Exist?

    Directory of Open Access Journals (Sweden)

    Lorenzo Ornaghi

    2017-05-01

    Full Text Available Large periods of history are usually characterized by equally important moments of change in scientific knowledge and, in particular, in the understanding of political power. We still need to study in depth whether the former provokes (almost of out necessity the latter, or whether they are “great” because they are favored by the innovation of the paradigms of knowledge. The passage from medieval universalism to the particularism of the modern age represents an extremely interesting analogy when compared to the transformations that are now underway. The example of John of Salisbury’s Policratus, the starting point of this article, is illuminating in our comprehension of the relevance of the interweaving between the persistence of the ancient forms of recognition of power and the search for new forms. The existence of glocal realities is already a fact. Even if it is relatively easy to recognize these realities (a business, a university, a humanitarian association, not a few of the same “parts” which constitute the traditional organization of the State, it is more difficult to define the specific characteristics of the power at their disposal. Moving from the widening gap between “actual” power and “potential” power, the article examines the motives for which the classical definitions of power are always becoming more insufficient in understanding the role now emerging from glocal realities. And, in particular, by looking at how the “command-obedience” relationship is changing also as a consequence of communication networks and information technology, the article analyzes that specific “contamination” within global elements and local elements, which seems to be the main base of glocal political power.

  17. TODAY WITH TROIKA; WHICH IS THE NATURAL ORDER OF THINGS?

    Directory of Open Access Journals (Sweden)

    André Correia de Sá

    2013-11-01

    Full Text Available Juliet, the main female figure of the Ordem Natural das Coisas, oscillates in two interpenetrated narrative movements: the extreme representation of a simulated existence and an ironic deployment of an author that sees the novel as a self-reflective puzzle. The cohesion between these two symbolic systems is given by setting the diegesis in a depressive universe, through a poetics of death and silence with unparalleled lyrical effects. In this essay we seek light in some of these cases, crossing them, in some way, with the state of siege experienced by portuguese society in 2013. 

  18. Photonics-physics and industry-today and tomorrow

    Sceats, M.

    2002-01-01

    Full text: Photonics research in Australia has been boosted over the past decade by various collaborative R and D programs that highlight the interplay between physics and industry. This research was built from a strong foundation in the fundamental theory of fibre and waveguide device design that provided not only a platform for applied R and D that has led to significant industry activities, but continues in new areas such as spatial solitons and photonic microstructures. The critical step from an industry perspective has been to build on these insights through materials science, to deliver new manufacturing technologies for photonics components and fibres. The chemistry and physics of photo-induced defects in silicate glasses, when combined with novel UV-writing interferometers, has provided a number of new approaches to the writing of Bragg gratings in fibres and waveguides. These gratings, developed for communications applications with strong industry support, have such an outstanding performance that they will certainly be deployed in many areas of optics. Polymer technologies have now been developed to the point where its performance as a platform meets the same specifications as required for silica based devices, with room for ongoing improvement using the versatility that polymers provide. It is worthwhile speculating on the future The narrowing gap between the conductivity of polymers and traditional semiconductors would indicate that the long awaited fusion of photonics and high-speed electronics might take place in polymer materials. Photonic microstructures provide the route to miniaturisation of photonics. The ability of photons to control the conduction of free electrons, and the spin states of bound electrons, in these materials would then provide a platform for quantum processing and transport of information, with profound implications for security and encryption. This is a rich area for research, with profound technological impacts. It is
