  1. CERTS: Consortium for Electric Reliability Technology Solutions - Research Highlights

    Energy Technology Data Exchange (ETDEWEB)

    2003-07-30

    Historically, the U.S. electric power industry was vertically integrated, and utilities were responsible for system planning, operations, and reliability management. As the nation moves to a competitive market structure, these functions have been disaggregated, and no single entity is responsible for reliability management. As a result, new tools, technologies, systems, and management processes are needed to manage the reliability of the electricity grid. However, a number of simultaneous trends prevent electricity market participants from pursuing development of these reliability tools: utilities are preoccupied with restructuring their businesses, research funding has declined, and the formation of Independent System Operators (ISOs) and Regional Transmission Organizations (RTOs) to operate the grid means that control of transmission assets is separate from ownership of these assets; at the same time, business uncertainty, and changing regulatory policies have created a climate in which needed investment for transmission infrastructure and tools for reliability management has dried up. To address the resulting emerging gaps in reliability R&D, CERTS has undertaken much-needed public interest research on reliability technologies for the electricity grid. CERTS' vision is to: (1) Transform the electricity grid into an intelligent network that can sense and respond automatically to changing flows of power and emerging problems; (2) Enhance reliability management through market mechanisms, including transparency of real-time information on the status of the grid; (3) Empower customers to manage their energy use and reliability needs in response to real-time market price signals; and (4) Seamlessly integrate distributed technologies--including those for generation, storage, controls, and communications--to support the reliability needs of both the grid and individual customers.

    RD&D on the CERTS Microgrid Concept builds upon this base of technical accomplishments to prioritize, develop, and then demonstrate technology enhancements to further enhance the business case for microgrids. That is, having demonstrated the technical feasibility of microgrid functions, RD&D optimization efforts are now needed to accelerate commercial deployment. The current phase is a contribution to these efforts. This project involved seven distinct analysis, bench-, and full-scale testing tasks. The first five tasks were described in the original proposal submitted and awarded through DOE's solicitation. Two additional tasks were added to address issues that had been identified in the earlier, first phase of testing.

    The objective of the CERTS Microgrid Test Bed project was to enhance the ease of integrating energy sources into a microgrid. The project accomplished this objective by developing and demonstrating three advanced techniques, collectively referred to as the CERTS Microgrid concept, that significantly reduce the level of custom field engineering needed to operate microgrids consisting of generating sources less than 100kW. The techniques comprising the CERTS Microgrid concept are: 1) a method for effecting automatic and seamless transitions between grid-connected and islanded modes of operation, islanding the microgrid's load from a disturbance, thereby maintaining a higher level of service, without impacting the integrity of the utility's electrical power grid; 2) an approach to electrical protection within a limited source microgrid that does not depend on high fault currents; and 3) a method for microgrid control that achieves voltage and frequency stability under islanded conditions without requiring high-speed communications between sources. These techniques were demonstrated at a full-scale test bed built near Columbus, Ohio and operated by American Electric Power. The testing fully confirmed earlier research that had been conducted initially through analytical simulations, then through laboratory emulations,and finally through factory acceptance testing of individual microgrid components. The islanding and resychronization method met all Institute of Electrical and Electronics Engineers Standard 1547 and power quality requirements. The electrical protection system was able to distinguish between normal and faulted operation. The controls were found to be robust under all conditions, including difficult motor starts and high impedance faults. The results from these tests are expected to lead to additional testing of enhancements to the basic techniques at the test bed to improve the business case for microgrid technologies, as well to field

    CERTS Microgrid concept captures the emerging potential of distributed generation using a system approach. CERTS views generation and associated loads as a subsystem or a 'microgrid'. The sources can operate in parallel to the grid or can operate in island, providing UPS services. The system can disconnect from the utility during large events (i.e. faults, voltage collapses), but may also intentionally disconnect when the quality of power from the grid falls below certain standards. CERTS Microgrid concepts were demonstrated at a full-scale test bed built near Columbus, Ohio and operated by American Electric Power. The testing fully confirmed earlier research that had been conducted initially through analytical simulations, then through laboratory emulations, and finally through factory acceptance testing of individual microgrid components. The islanding and resynchronization method met all Institute of Electrical and Electronics Engineers Standard 1547 and power quality requirements. The electrical protection system was able to distinguish between normal and faulted operation. The controls were found to be robust under all conditions, including difficult motor starts and high impedance faults.

    The first unified synthetic route to the four enantiopure HPA-12 stereoisomers in multi-gram scale is reported based on Crystallization-Induced Asymmetric Transformation (CIAT) technology. This preparative stereoselective synthesis allowed the unprecedented comparative evaluation of HPA-12 stereoisomers regarding their interaction with the CERT START domain. In vitro binding assay coupled to in silico docking approach indicate a possible interaction for the four derivatives. The first TR-FRET homogeneous-phase assay was developed to quantify their binding to the START domain, allowing complete determination of HPA-12 EC₅₀. Results indicate that not only the (1R,3S) lead to the strongest binding, but that both 1R and 3S stereocenters similarly contribute to extent of recognition This automated homogenous assay further opens up promising prospect for the identification of novel potential CERT antagonist by means of high throughput screening.

  14. The CERTS microgrid and the future of the macrogrid

    2004-06-01

    The blackouts of summer 2003 underscored the dependence of western economies on reliable supply of electricity with tight tolerances of quality. While demand for electricity continues to grow, expansion of the traditional electricity supply system is constrained and is unlikely to keep pace with the growing thirst western economies have for electricity. Furthermore, no compelling case has been made that perpetual improvement in the overall power quality and reliability (PQR) delivered is possible or desirable. An alternative path to providing for sensitive loads is to provide for generation close to them. This would alleviate the pressure for endless improvement in grid PQR and might allow the establishment of a sounder economically based level of universal grid service. Providing for loads by means of local power generation is becoming increasingly competitive with central station generation for a number of reasons, four key ones being non-technical constraints on expansion of the grid, improvements in small scale technologies, opportunities for CHP application, and the ubiquitous nature of sensitive loads in advanced economies. Along with these new technologies, concepts for operating them partially under local control in microgrids are emerging, the CERTS Microgrid being one example. It has been demonstrated in simulation, and a laboratory test of a three microturbine system is planned for early 2005, to be followed by a field demonstration. A systemic energy analysis of a southern California naval base building demonstrates a current economic on-site power opportunity.

  1. Testing First-Order Logic Axioms in AutoCert

    Science.gov (United States)

    Ahn, Ki Yung; Denney, Ewen

    2009-01-01

    AutoCert [2] is a formal verification tool for machine generated code in safety critical domains, such as aerospace control code generated from MathWorks Real-Time Workshop. AutoCert uses Automated Theorem Provers (ATPs) [5] based on First-Order Logic (FOL) to formally verify safety and functional correctness properties of the code. These ATPs try to build proofs based on user provided domain-specific axioms, which can be arbitrary First-Order Formulas (FOFs). These axioms are the most crucial part of the trusted base, since proofs can be submitted to a proof checker removing the need to trust the prover and AutoCert itself plays the part of checking the code generator. However, formulating axioms correctly (i.e. precisely as the user had really intended) is non-trivial in practice. The challenge of axiomatization arise from several dimensions. First, the domain knowledge has its own complexity. AutoCert has been used to verify mathematical requirements on navigation software that carries out various geometric coordinate transformations involving matrices and quaternions. Axiomatic theories for such constructs are complex enough that mistakes are not uncommon. Second, adjusting axioms for ATPs can add even more complexity. The axioms frequently need to be modified in order to have them in a form suitable for use with ATPs. Such modifications tend to obscure the axioms further. Thirdly, speculating validity of the axioms from the output of existing ATPs is very hard since theorem provers typically do not give any examples or counterexamples.

    Historically, American Indian Tribes have lacked sufficient numbers of trained, technical personnel from their communities to serve their communities; tribal expertise in the fields of science, business and engineering being extremely rare and programs to encourage these disciplines almost non-existent. Subsequently, Tribes have made crucial decisions about their land and other facets of Tribal existence based upon outside technical expertise, such as that provided by the United States government and/or private industries. These outside expert opinions rarely took into account the traditional and cultural values of the Tribes being advised. The purpose of this internship was twofold: Create and maintain a working relationship between CERT and Colorado State University (CSU) to plan for the Summit on Tribal human resource development; and Evaluate and engage in current efforts to strengthen the Tribal Resource Institute in Business, Engineering and Science (TRIBES) program. The intern lists the following as the project results: Positive interactions and productive meetings between CERT and CSU; Gathered information from Tribes; CERT database structure modification; Experience as facilitator in participating methods; Preliminary job descriptions for staff of future TRIBES programs; and Additions for the intern`s personal database of professional contacts and resources.

  5. Landmine research: technology solutions looking for problems

    Trevelyan, James P.

    2004-09-01

    The global landmine problem came to the attention of researchers in the mid 1990's and by 1997 several advanced and expensive sensor research programs had started. Yet, by the end of 2003, there is little sign of a major advance in the technology available to humanitarian demining programs. Given the motivation and dedication of researchers, public goodwill to support such programs, and substantial research resources devoted to the problem, it is worth asking why these programs do not seem to have had an impact on demining costs or casualty rates. Perhaps there are factors that have been overlooked. This paper reviews several research programs to gain a deeper understanding of the problem. A possible explanation is that researchers have accepted mistaken ideas on the nature of the landmine problems that need to be solved. The paper provides several examples where the realities of minefield conditions are quite different to what researchers have been led to believe. Another explanation may lie in the political and economic realities that drive the worldwide effort to eliminate landmines. Most of the resources devoted to landmine clearance programs come from humanitarian aid budgets: landmine affected countries often contribute only a small proportion because they have different priorities based on realistic risk-based assessment of needs and political views of local people. Some aid projects have been driven by the need to find a market for demining technologies rather than by user needs. Finally, there is a common misperception that costs in less developed countries are intrinsically low, reflecting low rates paid for almost all classes of skilled labour. When actual productivity is taken into account, real costs can be higher than industrialized countries. The costs of implementing technological solutions (even using simple technologies) are often significantly under-estimated. Some political decisions may have discouraged thorough investigation of cost

    Texas has for more than a decade led all other states in the U.S. with the most wind generation capacity on the U.S. electric grid. The State recognized the value that wind energy could provide, and committed early on to build out the transmission system necessary to move power from the windy regions in West Texas to the major population centers across the state. It also signaled support for renewables on the grid by adopting an aggressive renewable portfolio standard (RPS). The joining of these conditions with favorable Federal tax credits has driven the rapid growth in Texas wind capacity since its small beginning in 2000. In addition to the major transmission grid upgrades, there have been a number of technology and policy improvements that have kept the grid reliable while adding more and more intermittent wind generation. Technology advancements such as better wind forecasting and deployment of a nodal market system have improved the grid efficiency of wind. Successful large scale wind integration into the electric grid, however, continues to pose challenges. The continuing rapid growth in wind energy calls for a number of technology additions that will be needed to reliably accommodate an expected 65% increase in future wind resources. The Center for the Commercialization of Electric Technologies (CCET) recognized this technology challenge in 2009 when it submitted an application for funding of a regional demonstration project under the Recovery Act program administered by the U.S. Department of Energy1. Under that program the administration announced the largest energy grid modernization investment in U.S. history, making available some $3.4 billion in grants to fund development of a broad range of technologies for a more efficient and reliable electric system, including the growth of renewable energy sources like wind and solar. At that time, Texas was (and still is) the nation’s leader in the integration of wind into the grid, and was investing heavily

    Texas has for more than a decade led all other states in the U.S. with the most wind generation capacity on the U.S. electric grid. The State recognized the value that wind energy could provide, and committed early on to build out the transmission system necessary to move power from the windy regions in West Texas to the major population centers across the state. It also signaled support for renewables on the grid by adopting an aggressive renewable portfolio standard (RPS). The joining of these conditions with favorable Federal tax credits has driven the rapid growth in Texas wind capacity since its small beginning in 2000. In addition to the major transmission grid upgrades, there have been a number of technology and policy improvements that have kept the grid reliable while adding more and more intermittent wind generation. Technology advancements such as better wind forecasting and deployment of a nodal market system have improved the grid efficiency of wind. Successful large scale wind integration into the electric grid, however, continues to pose challenges. The continuing rapid growth in wind energy calls for a number of technology additions that will be needed to reliably accommodate an expected 65% increase in future wind resources.

    The continual scaling down of Si C-MOS circuits, the current annual doubling of magnetic storage density, and the regularly increasing capacity of fiber optic communications have resulted in enormous technological change, including a revolutionary transformation of all areas of science and engineering. Indeed the current capabilities of these information technologies both provide the quintessential demonstration that microtechnology, which is now transitioning to nanotechnology, can have tremendous societal impact, and provide essential means and methods by which other aspects of nanotechnology R can now be pursued. If the pace of advance in these information technologies is to be continued well into the future, new approaches and new solutions will be required to overcome the challenges this objective will entail. Nanoscaled material systems and new types of nanoscale devices have substantial promise for providing the basis for effective solutions to a number of these challenges. In this presentation I will briefly discuss research in the areas of nanoelectronics, nanophotonics and nanomagnetics that seeks to establish and develop some of these solutions. These include a radical new approach to Si electronics at the 10 nm scale, the use of nanoscaled materials to enable new photonic capabilities, and a new approach to manipulate nanomagnets for potential information storage and communication applications.

    Facilities and amenities management is amongst the core functionalities of local government. Considering the vast area that local government has to manage, a smart solution is extremely inevitable to solve issues such as inefficient maintenance of public parks, drainage system and so forth. Therefore, this paper aims to offer a smart city solution which exploits the benefit of space technology. This proposed solution is one of the modules developed in Spatial Smart City Service Delivery Engine (SSC SDE) Project undertaken by Agensi Angkasa Negara (ANGKASA). Various levels of local government have been chosen to understand real issues faced by them. Based on this data, a Smart Facility application has been developed with the aim to enhance the service delivery by the local government hence improving citizens’ satisfaction. Since this project is still in progress, this paper will merely discussing the concept of this application.

    Full Text Available The aim of the research is to create innovative evaporating equipment that can produce concentrates with a high content of solids, with a low level of thermal effects on raw materials. The significance of the solution of technological problems of the key process of food technologies - concentration of liquid solutions (juices, extracts, etc. is shown. Problems and scientific contradictions are formulated and the hypothesis on using of electromagnetic energy sources for direct energy transfer to solution’s moisture has been offered. The prospects of such an energy effect are proved by the energy management methods. The schemes of fuel energy conversion for the conventional thermal concentration technology and the innovative plant based on the electromagnetic energy generators are presented. By means of the similarity theory the obtained model is transformed to the criterial one depicted kinetic of evaporation process at the electromagnetic field action. The dimensionless capacity of the plant is expressed by the dependence between the Energetic effect number and relative moisture content. The scheme of automated experimental system for study of the evaporation process in the microwave field is shown. The experimental results of juice evaporation are presented. It has been demonstrated that the technologies of selective energy supply represent an effective tool for improvement of juice concentration evaporative plants. The main result of the research is design of the evaporator that allows reaching juice concentrates with °brix 95 at the temperature as low as 35 °С, i.e. 2…3 times superior than traditional technologies.

  3. Women, e-waste, and technological solutions to climate change.

    2014-06-14

    In this paper, we argue that a crossover class of climate change solutions (which we term "technological solutions") may disproportionately and adversely impact some populations over others. We begin by situating our discussion in the wider climate discourse, particularly with regard to the Millennium Development Goals (MDGs) and the Basel Convention. We then suggest that many of the most attractive technological solutions to climate change, such as solar energy and electric car batteries, will likely add to the rapidly growing stream of electronic waste ("e-waste"). This e-waste may have negative downstream effects on otherwise disenfranchised populations. We argue that e-waste burdens women unfairly and disproportionately, affecting their mortality/morbidity and fertility, as well as the development of their children. Building on this, we claim that these injustices are more accurately captured as problems of recognition rather than distribution, since women are often institutionally under-acknowledged both in the workplace and in the home. Without institutional support and representation, women and children are deprived of adequate safety equipment, health precautions, and health insurance. Finally, we return to the question of climate justice in the context of the human right to health and argue for greater inclusion and recognition of women waste workers and other disenfranchised groups in forging future climate agreements.

    CER tests were conducted to evaluated the effect of heat treatment on IGSCC susceptibility in 140 deg C 50% caustic solution at -900mVSCE. The results are as follows: 1) Heat treatment at low temperature for long time (600 deg C for 260hr) does not induce any caustic IG cracking, 2) grain boundaries appear to act as a preferential crack path when grain boundary carbon segregation is likely, 3) IGSCC in caustic solution does not seem to be caused by chromium depletion, 4) it is unlikely that grain boundary IG carbides play a role in caustic IGSCC susceptibility, and 5) carbon in solution enhanced the dissolution rate of alloy 600 significantly in 140 deg C 50% NaOH solution at -900mVSCE. Reverse U-bend test were conducted to evaluate IGSCC susceptibility of alloy 690 TT in 400 deg C 120bar steam for 1500hr. The results show that a tube from Inco ingot showed 100 {mu}m crack whereas a tube made by Chang Won Steel Co. does not show any crack at all. 16 refs., 30 figs., 3 tabs. (Author)

    Printed electronics have been introduced into the commercial markets in recent years. Various printing technologies have emerged aiming to process printed electronic devices with low cost, environmental friendliness, and compatibility with large areas and flexible substrates. The aim of this study is to propose a continuous solution dispensing technology for processing all-printed thin-film capacitors on glass substrates using a leading-edge printing instrument. Among all printing technologies, this study provides concrete proof of the following outstanding advantages of this technology: high tolerance to inks, high throughput, low cost, and precise pattern transfers. Ag nanoparticle ink based on glycol ethers was used to print the electrodes. To obtain dielectric ink, a copolymer powder of poly(methyl methacrylate-co-benzoylphenyl methacrylate) containing crosslinkable side groups was dissolved in anisole. Various layouts were designed to support multiple electronic applications. Scanning electron microscopy and atomic force microscopy were used to investigate the all-printed capacitor layers formed using the proposed process. Additionally, the printed capacitors were electrically characterized under direct current and alternating current. The measured electrical properties of the printed capacitors were consistent with the theoretical results.

  8. Efficient trafficking of ceramide from the endoplasmic reticulum to the Golgi apparatus requires a VAMP-associated protein-interacting FFAT motif of CERT.

    Science.gov (United States)

    Kawano, Miyuki; Kumagai, Keigo; Nishijima, Masahiro; Hanada, Kentaro

    2006-10-01

    Ceramide is synthesized at the endoplasmic reticulum (ER) and transported to the Golgi apparatus by CERT for its conversion to sphingomyelin in mammalian cells. CERT has a pleck-strin homology (PH) domain for Golgi targeting and a START domain catalyzing the intermembrane transfer of ceramide. The region between the two domains contains a short peptide motif designated FFAT, which is supposed to interact with the ER-resident proteins VAP-A and VAP-B. Both VAPs were actually co-immunoprecipitated with CERT, and the CERT/VAP interaction was abolished by mutations in the FFAT motif. These mutations did not affect the Golgi targeting activity of CERT. Whereas mutations of neither the FFAT motif nor the PH domain inhibited the ceramide transfer activity of CERT in a cell-free system, they impaired the ER-to-Golgi transport of ceramide in intact and in semi-intact cells at near endogenous expression levels. By contrast, when overexpressed, both the FFAT motif and the PH domain mutants of CERT substantially supported the transport of ceramide from the ER to the site where sphingomyelin is produced. These results suggest that the Golgi-targeting PH domain and ER-interacting FFAT motif of CERT spatially restrict the random ceramide transfer activity of the START domain in cells.

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

    2015-04-01

    The growth in environmental pollution alongside an increasing demand for electricity in Kazakhstan calls for a higher level of renewable energy penetration into national power systems. Kazakhstan has great potential for renewable energies from wind, solar, hydro and biomass resources that can be exploited for electricity production. In 2013, the Kazakhstani Ministry of Energy initiated a new power development plan, which aims to bring the share of renewable energy to 3% by 2020 rising to 30% by 2030 and 50% by 2050. The current contribution of renewable energy resources in the national electricity mix, however, is less than 1%. As a developing country, Kazakhstan has faced a number of barriers to increase renewable energy use, which have to be analysed and translated into a comprehensive renewable energy policy framework. This study presents an overview of the current conditions of renewable energy development in Kazakhstan. Secondly, it identifies and describes the main barriers that prevent diffusion of renewable energy technologies in Kazakhstan. Finally, the paper provides solutions to overcome specific barriers in order to successfully develop a renewable energy technology sector in Kazakhstan.

    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.

    The ceramide transport protein CERT mediates the inter-organelle transport of ceramide for the synthesis of sphingomyelin, presumably through endoplasmic reticulum (ER)-Golgi membrane contact sites. CERT has a short peptide motif named FFAT, which associates with the ER-resident membrane protein VAP. We show that the phosphorylation of CERT at serine 315, which is adjacent to the FFAT motif, markedly enhanced the interaction of CERT with VAP. The phosphomimetic CERT S315E mutant exhibited higher activity to support the ER-to-Golgi transport of ceramide than the wild-type control in a semi-intact cell system, and this enhanced activity was abrogated when its FFAT motif was deleted. The level of phosphorylation of CERT at Ser-315 increased in HeLa cells treated with a sphingolipid biosynthesis inhibitor or exogenous sphingomyelinase. Expression of CERT S315E induced intracellular punctate structures, to which CERT and VAP were co-localized, and the occurrence of the structure was dependent on both phosphatidylinositol 4-monophosphate binding and VAP binding activities of CERT. Phosphorylation of another region (named a serine-rich motif) in CERT is known to down-regulate the activity of CERT. Analysis of various CERT mutant constructs showed that the de-phosphorylation of the serine-rich motif and the phosphorylation of Ser-315 likely have the additive contribution to enhance the activity of CERT. These results demonstrate that the phosphorylation of CERT at the FFAT motif-adjacent serine affected its affinity for VAP, which may regulate the inter-organelle trafficking of ceramide in response to the perturbation of cellular sphingomyelin and/or other sphingolipids.

    Recent advances in technology have led to the introduction of a variety of innovative devices, each with their own platform for data display, into the operating room (OR). While these innovative applications are expanding the traditional boundaries of the surgical space and enhancing treatment capabilities, the introduction of additional screens and displays is placing an ever-increasing load on the OR team. This review describes the main data display platforms currently available in ORs: computer monitors with CRT (cathode ray tube) or LCD (liquid crystal display) screens, suspended imaging displays, wearable computers (WC), auditory displays and tactile (haptic) displays. The different display platforms are evaluated according to their compatibility with the characteristics of the working environment (OR), the monitoring task, and the users (the surgical team). No single display configuration provides an ultimate solution for presenting patient data in the OR. A multi-sensory data display including visual, acoustic and haptic manipulation is suggested as a promising configuration for data display in the OR.

    There are growing concerns over future environmental impact and earth resource shortage throughout the world and in many industries. Our semiconductor industry is not excluded. "Green" has become an important topic as production volume become larger and more powerful. Especially, the rare gases are widely used in semiconductor manufacturing because of its inertness and extreme chemical stability. One major component of an Excimer laser system is Neon. It is used as a buffer gas for Argon (Ar) and Krypton (Kr) gases used in deep ultraviolet (DUV) lithography laser systems. Since Neon gas accounting for more than 96% of the laser gas mixture, a fairly large amount of neon gas is consumed to run these DUV lasers. However, due to country's instability both in politics and economics in Ukraine, the main producer of neon gas today, supply reduction has become an issue and is causing increasing concern. This concern is not only based on price increases, but has escalated to the point of supply shortages in 2015. This poses a critical situation for the semiconductor industry, which represents the leading consumer of neon gas in the world. Helium is another noble gas used for Excimer laser operation. It is used as a purge gas for optical component modules to prevent from being damaged by active gases and impurities. Helium has been used in various industries, including for medical equipment, linear motor cars, and semiconductors, and is indispensable for modern life. But consumption of helium in manufacturing has been increased dramatically, and its unstable supply and price rise has been a serious issue today. In this article, recent global supply issue of rare resources, especially Neon gas and Helium gas, and its solution technology to support semiconductor industry will be discussed.

    Computational software and custom-written codes play a key role in scientific research and teaching, providing tools to perform data analysis and forward modeling through numerical computation. However, development of these codes is often hampered by the fact that there is no well-defined way for the authors to receive credit or professional recognition for their work through the standard methods of scientific publication and subsequent citation of the work. This in turn may discourage researchers from publishing their codes or making them easier for other scientists to use. We investigate the issues involved in citing software in a scientific context, and introduce features that should be components of a citation infrastructure, particularly oriented towards the codes and scientific culture in the area of geodynamics research. The codes used in geodynamics are primarily specialized numerical modeling codes for continuum mechanics problems; they may be developed by individual researchers, teams of researchers, geophysicists in collaboration with computational scientists and applied mathematicians, or by coordinated community efforts such as the Computational Infrastructure for Geodynamics. Some but not all geodynamics codes are open-source. These characteristics are common to many areas of geophysical software development and use. We provide background on the problem of software citation and discuss some of the barriers preventing adoption of such citations, including social/cultural barriers, insufficient technological support infrastructure, and an overall lack of agreement about what a software citation should consist of. We suggest solutions in an initial effort to create a system to support citation of software and promotion of scientific software development.

    Snoeckx, Ramses; Bogaerts, Annemie

    2017-08-21

    CO2 conversion into value-added chemicals and fuels is considered as one of the great challenges of the 21st century. Due to the limitations of the traditional thermal approaches, several novel technologies are being developed. One promising approach in this field, which has received little attention to date, is plasma technology. Its advantages include mild operating conditions, easy upscaling, and gas activation by energetic electrons instead of heat. This allows thermodynamically difficult reactions, such as CO2 splitting and the dry reformation of methane, to occur with reasonable energy cost. In this review, after exploring the traditional thermal approaches, we have provided a brief overview of the fierce competition between various novel approaches in a quest to find the most effective and efficient CO2 conversion technology. This is needed to critically assess whether plasma technology can be successful in an already crowded arena. The following questions need to be answered in this regard: are there key advantages to using plasma technology over other novel approaches, and if so, what is the flip side to the use of this technology? Can plasma technology be successful on its own, or can synergies be achieved by combining it with other technologies? To answer these specific questions and to evaluate the potentials and limitations of plasma technology in general, this review presents the current state-of-the-art and a critical assessment of plasma-based CO2 conversion, as well as the future challenges for its practical implementation.

    Full Text Available The convergence of the ongoing innovations to make vehicles driverless, carbon free and accessible on ‘as needed’ basis, is evolving fast. A review of available information suggests that these technologies have substantial potential to generate positive externalities by improving road safety, lowering of fuel consumption and emissions in vehicles, and providing mobility options for vulnerable population including young, old and persons with disability. However, given the limited commercialization it is difficult to discern the nature of impact these technologies will have in reducing the two negative travel externalities, road congestion and low density expansion of cities. Gradual mainstreaming of these technologies will offer opportunities for further research in understanding the behavioral responses of their end users, and the risks that these technologies may pose to manufacturers, consumers, and stakeholders.

    2013-06-01

    Coal currently supplies with more than 40% of the world electricity consumption and it essential input of around 70% of world steel production, representing around 30% of the world primary energy supply. This is because coal is cheap, abundant, accessible, widely distributed and easy energy to transport, store and use. For these features, coal is projected to be intensively used in the future. Production and use of coal present a series of issues throughout the whole value chain. While existing technology allows addressing most of them (safety at work, land restoration, mercury, NOx and sulphur emissions avoidance, etc.), CO2 emissions continues to be the biggest challenge for coal use in the future. This report focuses on the technology path to near-zero emissions including useful insights in advanced coal power generation technologies and Carbon Capture, Utilisation and Storage, a promising technology with a large potential which can push Carbon Capture and Storage competitiveness. In addition, the report shows the features of the new generation of coal-fired power plants in terms of flexibility for dynamic operation and grid stability, requirements increasingly needed to operate on grids with significant wind and solar generation.

  15. The lipid transfer protein CERT interacts with the Chlamydia inclusion protein IncD and participates to ER-Chlamydia inclusion membrane contact sites.

    Directory of Open Access Journals (Sweden)

    Isabelle Derré

    2011-06-01

    Full Text Available Bacterial pathogens that reside in membrane bound compartment manipulate the host cell machinery to establish and maintain their intracellular niche. The hijacking of inter-organelle vesicular trafficking through the targeting of small GTPases or SNARE proteins has been well established. Here, we show that intracellular pathogens also establish direct membrane contact sites with organelles and exploit non-vesicular transport machinery. We identified the ER-to-Golgi ceramide transfer protein CERT as a host cell factor specifically recruited to the inclusion, a membrane-bound compartment harboring the obligate intracellular pathogen Chlamydia trachomatis. We further showed that CERT recruitment to the inclusion correlated with the recruitment of VAPA/B-positive tubules in close proximity of the inclusion membrane, suggesting that ER-Inclusion membrane contact sites are formed upon C. trachomatis infection. Moreover, we identified the C. trachomatis effector protein IncD as a specific binding partner for CERT. Finally we showed that depletion of either CERT or the VAP proteins impaired bacterial development. We propose that the presence of IncD, CERT, VAPA/B, and potentially additional host and/or bacterial factors, at points of contact between the ER and the inclusion membrane provides a specialized metabolic and/or signaling microenvironment favorable to bacterial development.

    Cell line development is the most critical and also the most time-consuming step in the production of recombinant therapeutic proteins. In this regard, a variety of vector and cell engineering strategies have been developed for generating high-producing mammalian cells; however, the cell line engineering approach seems to show various results on different recombinant protein producer cells. In order to improve the secretory capacity of a recombinant tissue plasminogen activator (t-PA)-producing Chinese hamster ovary (CHO) cell line, we developed cell line engineering approaches based on the ceramide transfer protein (CERT) and X-box binding protein 1 (XBP1) genes. For this purpose, CERT S132A, a mutant form of CERT that is resistant to phosphorylation, and XBP1s were overexpressed in a recombinant t-PA-producing CHO cell line. Overexpression of CERT S132A increased the specific productivity of t-PA-producing CHO cells up to 35%. In contrast, the heterologous expression of XBP1s did not affect the t-PA expression rate. Our results suggest that CERTS132A- based secretion engineering could be an effective strategy for enhancing recombinant t- PA production in CHO cells.

    2009-01-01

    A method of fracture boundary extraction was developed using the Gaussian template and Canny boundary detection on the basis of the collected digital images of natural fractures. The roughness and apertures of the fractures were briefly discussed from the point of view of digital image analysis. The extracted fractured image was translated into a lattice image which can be directly used in numerical simulation. The lattice Boltzmann and modified moment propagation mixed method was then applied to the simulation of solute transport in a natural single fracture, and this mixed method could take the advantages of the lattice Boltzmann method in dealing with complex physical boundaries. The obtained concentrations was fitted with the CXTFIT2.1 code and compared with the results obtained with the commercial software Feflow. The comparison indicates that the simulation using the mixed method is sound.

    The military uncooled infrared market is driven by the continued cost reduction of the focal plane arrays whilst maintaining high standards of sensitivity and steering towards smaller pixel sizes. As a consequence, new optical solutions are called for. Two approaches can come into play: the bottom up option consists in allocating improvements to each contributor and the top down process rather relies on an overall optimization of the complete image channel. The University of Rennes I with Thales Angénieux alongside has been working over the past decade through French MOD funding's, on low cost alternatives of infrared materials based upon chalcogenide glasses. A special care has been laid on the enhancement of their mechanical properties and their ability to be moulded according to complex shapes. New manufacturing means developments capable of better yields for the raw materials will be addressed, too. Beyond the mere lenses budget cuts, a wave front coding process can ease a global optimization. This technic gives a way of relaxing optical constraints or upgrading thermal device performances through an increase of the focus depths and desensitization against temperature drifts: it combines image processing and the use of smart optical components. Thales achievements in such topics will be enlightened and the trade-off between image quality correction levels and low consumption/ real time processing, as might be required in hand-free night vision devices, will be emphasized. It is worth mentioning that both approaches are deeply leaning on each other.

    Information and communication technology (ICT) is potentially mature enough to empower outdoor and social activities in dementia. However, actual ICT-based devices have limited functionality and impact, mainly limited to safety. What is an ideal operational framework to enhance this field to support outdoor and social activities? Review of literature and cross-disciplinary expert discussion. A situation-aware ICT requires a flexible fine-tuning by stakeholders of system usability and complexity of function, and of user safety and autonomy. It should operate by artificial intelligence/machine learning and should reflect harmonized stakeholder values, social context, and user residual cognitive functions. ICT services should be proposed at the prodromal stage of dementia and should be carefully validated within the life space of users in terms of quality of life, social activities, and costs. The operational framework has the potential to produce ICT and services with high clinical impact but requires substantial investment. Copyright © 2016 The Authors. Published by Elsevier Inc.

    Solution processed multilayer organic light-emitting diodes (OLEDs) present challenges, especially regarding dissolution of the first layer during deposition of a second layer. In this work, we first demonstrated a plasma cross-linking technology to produce a solution processed OLED. The surfaces of organic films can be cross-linked after mixed acetylene and Ar plasma treatment for several tens of seconds and resist corrosion of organic solvent. The film thickness and surface morphology of emissive layers (EMLs) with plasma treatment and subsequently spin-rinsed with chlorobenzene are nearly unchanged. The solution processed triple-layer OLED is successfully fabricated and the current efficiency increases 50% than that of the double-layer OLED. Fluorescent characteristics of EMLs are also observed to investigate factors influencing the efficiency of the triple-layer OLED. Plasma cross-linking technology may open up a new pathway towards fabrication of all-solution processed multilayer OLEDs and other soft electronic devices.

    Full Text Available Charge storage nonvolatile memory (NVM is one of the main driving forces in the evolution of IT handheld devices. Technology scaling of charge storage NVM has always been the strategy to achieve higher density NVM with lower cost per bit in order to meet the persistent consumer demand for larger storage space. However, conventional technology scaling of charge storage NVM has run into many critical reliability challenges related to fundamental device characteristics. Therefore, further technology scaling has to be supplemented with novel approaches in order to surmount these reliability issues to achieve desired reliability performance. This paper is focused on reviewing critical research findings on major reliability challenges and technical solutions to mitigate technology scaling challenges of charge storage NVM. Most of these technical solutions are still in research phase while a few of them are more mature and ready for production phase. Three of the mature technical solutions will be reviewed in detail, that is, tunnel oxide top/bottom nitridation, nanocrystal, and phase change memory (PCM. Key advantages and reported reliability challenges of these approaches are thoroughly reviewed in this paper. This paper will serve as a good reference to understand the future trend of innovative technical solutions to overcome the reliability challenges of charge storage NVM due to technology scaling.

    Full Text Available The fast development of ICTs pose new challenges to the European Union and its Member States. Every EU country has its own policies regarding technology transfer, ownership of state e-services, and the possibilities how the state-owned or licensed e-service could be exported. Taking into account the free movement of goods, the EU has created a platform to cooperate and export IT solutions. However, the lack of preparedness of infrastructures, legislation and stakeholders for cross-border exchanges poses a threat to IT transfer and should be taken into consideration in the EU as well. In the coming decades the number of outsourced ICT solutions, strategically important ICT solutions, public services and critically important information exchange platforms developed on behalf of the states, will grow exponentially. Still, digital development is uneven across the EU, they grow at different speeds and the performance is quite splintered. There are legal provisions which are outdated and therefore impede technological cooperation and export of IT solutions. A Member State may restrict the ICT licensing based on national security and policy reasons and the ownership of intellectual property might pose a threat to technology transfer or further development of the IT solution. There are examples of strategically important export of ICT solutions, the experience at which can be expanded to cover other EU Member States. Strong collaboration would enable mutual learning from past experiences along with the opportunities for better use of technology. Parallels can be drawn with military technology transfers, as the policies and legal framework was first developed and mostly used with them.

    Paulrud, Susanne; Roennbaeck, Marie; Ryde, Daniel; Laitila, Thomas

    2010-07-01

    Requirements and solutions for future pellet burning technologies Since 2006, sales of pellet burning technologies to the Swedish residential market have fallen. The main reasons for this decrease are: many of the economically favorable easy conversions from oil to pellets have been made; competition from heat pumps; warm winters; a stable electricity price; and the current structure of heating in residential buildings, where electric heating dominates. To change this falling trend pellets need to become more attractive to consumers. This project aimed to analyze the requirements for the next generation of pellets systems and to develop potential solutions, in collaboration with the pellets industry. More specifically, the study looked at consumers' attitudes toward heating choices and different heating through a survey to 2000 house owners across Sweden. The project included a market analysis of Swedish and international technologies and examines the conditions for Swedish pellet burning technology in different markets. In addition, new solutions and developments for Swedish pellets burning technology are described

  6. Chlamydia trachomatis co-opts GBF1 and CERT to acquire host sphingomyelin for distinct roles during intracellular development.

    Directory of Open Access Journals (Sweden)

    2011-09-01

    Full Text Available The strain designated Chlamydia trachomatis serovar that was used for experiments in this paper is Chlamydia muridarum, a species closely related to C. trachomatis (and formerly termed the Mouse Pneumonitis strain of C. trachomatis. [corrected]. The obligate intracellular pathogen Chlamydia trachomatis replicates within a membrane-bound inclusion that acquires host sphingomyelin (SM, a process that is essential for replication as well as inclusion biogenesis. Previous studies demonstrate that SM is acquired by a Brefeldin A (BFA-sensitive vesicular trafficking pathway, although paradoxically, this pathway is dispensable for bacterial replication. This finding suggests that other lipid transport mechanisms are involved in the acquisition of host SM. In this work, we interrogated the role of specific components of BFA-sensitive and BFA-insensitive lipid trafficking pathways to define their contribution in SM acquisition during infection. We found that C. trachomatis hijacks components of both vesicular and non-vesicular lipid trafficking pathways for SM acquisition but that the SM obtained from these separate pathways is being utilized by the pathogen in different ways. We show that C. trachomatis selectively co-opts only one of the three known BFA targets, GBF1, a regulator of Arf1-dependent vesicular trafficking within the early secretory pathway for vesicle-mediated SM acquisition. The Arf1/GBF1-dependent pathway of SM acquisition is essential for inclusion membrane growth and stability but is not required for bacterial replication. In contrast, we show that C. trachomatis co-opts CERT, a lipid transfer protein that is a key component in non-vesicular ER to trans-Golgi trafficking of ceramide (the precursor for SM, for C. trachomatis replication. We demonstrate that C. trachomatis recruits CERT, its ER binding partner, VAP-A, and SM synthases, SMS1 and SMS2, to the inclusion and propose that these proteins establish an on-site SM biosynthetic

  7. SHARING AND DEPLOYING INNOVATIVE INFORMATION TECHNOLOGY SOLUTIONS TO MANAGE WASTE ACROSS THE DOE COMPLEX

    Energy Technology Data Exchange (ETDEWEB)

    Crolley, R.; Thompson, M.

    2011-01-31

    There has been a need for a faster and cheaper deployment model for information technology (IT) solutions to address waste management needs at US Department of Energy (DOE) complex sites for years. Budget constraints, challenges in deploying new technologies, frequent travel, and increased job demands for existing employees have prevented IT organizations from staying abreast of new technologies or deploying them quickly. Despite such challenges, IT organizations have added significant value to waste management handling through better worker safety, tracking, characterization, and disposition at DOE complex sites. Systems developed for site-specific missions have broad applicability to waste management challenges and in many cases have been expanded to meet other waste missions. Radio frequency identification (RFID) and global positioning satellite (GPS)-enabled solutions have reduced the risk of radiation exposure and safety risks. New web-based and mobile applications have enabled precision characterization and control of nuclear materials. These solutions have also improved operational efficiencies and shortened schedules, reduced cost, and improved regulatory compliance. Collaboration between US Department of Energy (DOE) complex sites is improving time to delivery and cost efficiencies for waste management missions with new information technologies (IT) such as wireless computing, global positioning satellite (GPS), and radio frequency identification (RFID). Integrated solutions developed at separate DOE complex sites by new technology Centers of Excellence (CoE) have increased material control and accountability, worker safety, and environmental sustainability. CoEs offer other DOE sister sites significant cost and time savings by leveraging their technology expertise in project scoping, implementation, and ongoing operations.

    This paper reviews essential problems of water environment and trends of solution technologies related to water quality problems promoted by Fuji Electric. They have developed a water quality safety monitor for high-sensitivity monitoring of river water and lake water, and a water quality control system for supporting river managers during water quality accidents. For the water quality safety monitor, nitrification bacteria sensitive to toxicants are fixed as bacterial membrane, and it is attached on the dissolved oxygen electrode. Toxicants mixed in the river water can be detected by determining the activity of nitrification bacteria from the change of dissolved oxygen consumption. This provides ten times of detecting sensibility compared with fish. A coagulation sensor has been also developed for the low turbidity operation during water purifying process and the optimal injection of coagulants. High-performance ozonizers have been developed for advanced treatment of purified water. Using this, nasty smell and precursors of trihalomethane in drinking water can be strongly decomposed. For the field of sewage water, a biosensor has been developed. It takes only 20 minutes to measure BOD, which took 5 days previously. For the treatment technology, a two-tank type intermittent aeration activated sludge process has been completed, which provides a remarkable removing effect of nitrogen and phosphorus in sewage water. 18 refs., 2 figs.

    2012-06-01

    Soft robotics is a current focus in robotics research because of the expected capability of soft robots to better interact with real-world environments. As a point of inspiration in the development of innovative technologies in soft robotics, octopuses are particularly interesting 'animal models'. Octopus arms have unique biomechanical capabilities that combine significant pliability with the ability to exert a great deal of force, because they lack rigid structures but can change and control their degree of stiffness. The octopus arm motor capability is a result of the peculiar arrangement of its muscles and the properties of its tissues. These special abilities have been investigated by the authors in a specific study dedicated to identifying the key principles underlying these biological functions and deriving engineering requirements for robotics solutions. This paper, which is the second in a two-part series, presents how the identified requirements can be used to create innovative technological solutions, such as soft materials, mechanisms and actuators. Experiments indicate the ability of these proposed solutions to ensure the same performance as in the biological model in terms of compliance, elongation and force. These results represent useful and relevant components of innovative soft-robotic systems and suggest their potential use to create a new generation of highly dexterous, soft-bodied robots.

    2014-04-01

    Organic field-effect transistors (OFETs) are fundamental building blocks for various state-of-the-art electronic devices. Solution-processed organic crystals are appreciable materials for these applications because they facilitate large-scale, low-cost fabrication of devices with high performance. Patterning organic crystal transistors into well-defined geometric features is necessary to develop these crystals into practical semiconductors. This review provides an update on recent development in patterning technology for solution-processed organic crystals and their applications in field-effect transistors. Typical demonstrations are discussed and examined. In particular, our latest research progress on the spin-coating technique from mixture solutions is presented as a promising method to efficiently produce large organic semiconducting crystals on various substrates for high-performance OFETs. This solution-based process also has other excellent advantages, such as phase separation for self-assembled interfaces via one-step spin-coating, self-flattening of rough interfaces, and in situ purification that eliminates the impurity influences. Furthermore, recommendations for future perspectives are presented, and key issues for further development are discussed.

    The regeneration of chromium (VI) and the recovery of etched copper from chromium etching solutions by electrodialysis is improved by the addition of a concentrator cell in the catholyte chamber. The concentrator media used are ion-exchange resins or activated carbon cloth. The maximum percentages for the regeneration of chromium and recovery of copper in these systems is however less than 80% and 90% respectively because of the competition between the processes of oxidation of Cr(III) and electrodeposition of copper. A novel combination of electrolysis with electrodialysis and concentrator cell technology is developed that achieves 92% chromium regeneration and 90% copper recovery.

    2011-09-01

    Full Text Available This paper examines issues around learning ‘content’ and its place in the new digital learning culture. We focus on the increasing demands of digital learners for content that is relevant and the challenges this poses if educators are to stay relevant to them. We say ‘relevance’ is best achieved when content is negotiated with learners in collaboration with instructors. We describe strategies in which technology enhanced teaching and learning solutions have enabled learners to negotiate and create digitised learning content that is educationally, culturally and socially relevant. We cite two case studies that exemplify this approach: a trial of negotiated content with primary school aged digital learners at Brisbane School of Distance Education (BSDE, Australia, and the content decision-making processes used for the development of e-learning courses for hearing health professionals and Auditory-Verbal Therapy at Hear and Say WorldWide Brisbane, Australia. We focus on the changing demands and skill sets of digital learners, their learning managers and subject matter experts, and the use of technology enhanced teaching and learning solutions as the negotiating tool in the development of digital content that is academically rigorous and also learner friendly.

    Nowadays a great number of applications are used to compile and transmit casualties and disasters information but there are many troubles associated with the technology as can be the communications reliability and the size and weight of the devices medical staff has to carry with. Telecommunication infrastructures support information movement among geographically dispersed locations. Recently a large family of little devices has appeared in the buyer's market. They are called Personal Digital Assistants and because of their physic and technical features, they are very useful in the emergency field. As for the communications reliability, many technologies have been developed in the last years but it is necessary to find a solution that can be used in whatever situation independently of the emergency circumstances. Facing this reality, the Spanish government funded REMAF, an ATYCA (Initiative of Support for the Technology, Security and Quality in the Industry) project. REMAF joined research groups (UPM), phone operators (Fundación Airtel Móvil) and end users (SAMUR) to build a disaster data management system conceived to use modern telemedicine systems to optimize the management in these situations, taking the advantage of the above mentioned mobile communication tools and networks.

    Full Text Available In this paper, we present a new approach to the fabrication of integrated silicon-based piezoelectric diaphragm-type biosensors by using sodium potassium niobate-silver niobate (0.82KNN-0.18AN composite lead-free thin film as the piezoelectric layer. The piezoelectric diaphragms were designed and fabricated by micro-machining technology and chemical solution deposition. The fabricated device was very sensitive to the mass changes caused by various targets attached on the surface of diaphragm. The measured mass sensitivity value was about 931 Hz/μg. Its good performance shows that the piezoelectric diaphragm biosensor can be used as a cost-effective platform for nucleic acid testing.

    2002-03-01

    The combination of high voltage pulse discharge and ozonation as an advanced oxidation technology was used to investigate the degradation of 4-chlorophenol (4-CP) in water. The factors that affect the rate of degradation were discussed. The 1.95 x 10(-3) mol/L solutions of 4-CP were almost completely (96%) degraded after the discharge treatment of 30 min. The degradation of 4-CP was investigated as a function of the ozone concentration, radical scavenger and electrode distance. The rate of 4-CP degradation increases with an increase in ozone concentration and a decrease in the electrode distance from 20 mm to 10 mm. The presence of radical scavenger decreased the rate of 4-CP degradation.

    The two-year Department of Energy (DOE) project ''Treatment of Cyanide Solutions and Slurries Using Air-Sparged Hydrocyclone (ASH) Technology'' (ASH/CN) has been completed. This project was also sponsored by industrial partners, ZPM Inc., Elbow Creek Engineering, Solvay Minerals, EIMCO-Baker Process, Newmont Mining Corporation, Cherokee Chemical Co., Placer Dome Inc., Earthworks Technology, Dawson Laboratories and Kennecott Minerals. Development of a new technology using the air-sparged hydrocyclone (ASH) as a reactor for either cyanide recovery or destruction was the research objective. It was expected that the ASH could potentially replace the conventional stripping tower presently used for HCN stripping and absorption with reduced power costs. The project was carried out in two phases. The first phase included calculation of basic processing parameters for ASH technology, development of the flowsheet, and design/adaptation of the ASH mobile system for hydrogen cyanide (HCN) recovery from cyanide solutions. This was necessary because the ASH was previously used for volatile organics removal from contaminated water. The design and modification of the ASH were performed with the help from ZPM Inc. personnel. Among the modifications, the system was adapted for operation under negative pressure to assure safe operating conditions. The research staff was trained in the safe use of cyanide and in hazardous material regulations. Cyanide chemistry was reviewed resulting in identification of proper chemical dosages for cyanide destruction, after completion of each pilot plant run. The second phase of the research consisted of three field tests that were performed at the Newmont Mining Corporation gold cyanidation plant near Midas, Nevada. The first field test was run between July 26 and August 2, 2002, and the objective was to demonstrate continuous operation of the modified ASH mobile system. ASH units were applied for both stripping and absorption

    In this work, nano-sized bismuth (Bi) binding technology has been developed in order to improve the electrochemical characteristics of Bi for detecting heavy metals. A Bi nanopowder synthesized by gas condensation (GC) method exhibits a size smaller than 100 nm. The Bi nanoparticles are uniformly distributed on a carbon surface with strong chemical bonding by using a Nafion solution. The optimum additional amount of Nafion is suggested for dispersion stability and phase stability of the Bi nanoparticles. The detection sensitivity and the detection limit of the nano-Bi fixed electrode are quantitatively estimated from analyses of square wave anodic stripping voltammograms (SWASV). The proposed 'mercury-free' carbon strip electrode, modified with a Bi nanopowder, is conveniently to use and is directly applicable to trace metal analysis with neither pre-deposition of Bi nor complicated surface polishing steps.

    In this paper, Pt-ZnO hybrid nanocomposites were prepared by solution plasma technology. X-ray diffraction (XRD) and energy dispersive x-ray analysis (EDX) were used to verify their chemical composition. The size and morphology of the Pt-ZnO hybrid nanocomposites were characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). These results indicate that about 2-3 nm Pt nanoparticles (NPs) were synthesized and dispersed on the pyramid-like ZnO (20-60 nm) surface. Photodegradation of Rhodamine B (RhB) demonstrates that the Pt (5 wt%)-ZnO hybrid nanocomposite has better photocatalytic activity than commercial P25 because Pt NPs restrain the photogenerated electron/hole recombination and increase the catalyst activity.

    Waste water, drinking water and other industrial water sources are more and more/increasingly polluted with a large variety of contaminants, such as pesticides or residuals of pharmaceuticals. These compounds can impact human and animal organisms and lead to serious health issues. Today, in order to analyze the presence and quantity of the abovementioned micropollutants, samples are typically sent to specialized centralized laboratories and their processing may take up to several days. In order to meet the demand for continuous and consistent monitoring of aqueous solutions we propose a novel label-free technology system comprising proprietary chip and reader device designs. The core of the system is constituted by a planar-grated-waveguide (PGW) chip. Label-free biosensors, based on PGWs are sensitive to effective refractive index changes caused by the adsorption of biomolecules (micropollutants) onto the sensor surface or due to refractive index changes of the bulk solution. The presented reader device operates with a novel readout concept based on a scanning MEMS mirror for the angular interrogation of input grating couplers at a high repetition rate. The reader has fully integrated optics, electronics and fluidics and at the same time consumes limited energy (portable, field use ready). In the recent experiments, the effectiveness of the technology has been demonstrated with various liquids and bioassays showing (i) an excellent refractometric sensitivity with a limit of detection towards effective refractive index changes of ▵neff < 2 x 10-7, and (ii) the capability to perform affinity measurements for large (<150 kDa) and small (<250 Da) molecules.

    2016-04-01

    Full Text Available We have provided technical solutions to improve performance of technological systems for the preparation of solutions and concrete based on the use of screw rotors in the form of drums with helix lines formed on the perimeter as interconnect lines of his spiral surfaces. We discuss the six varieties of devices and installations for mixing, including concrete mixers, reels which are of a complicated geometric body formed by helical surfaces with variable or constant pitch and which creates screw lines in the places of their connection. In the form of screw drums, they may be conical, concave, convex, cylindrical. The experimental test was conducted on the concrete mixer drums, which are arranged one in the other. The implementation of the mixer in the form of coaxially edited two barrels provides not only a reduction in size in length, but a significant reduction in energy consumption due to the use of heat, released during the activation process of inert heating of the concrete mix as when re-mixing and concrete mix when mixing it with water and transportation. The drums of such systems is made of flat elements with the formation of the helical lines discretely spaced around the perimeter of different pitch and with different numbers directed towards each other helical surfaces. In the process of transporting the components of concrete in the internal screw drum there is active mixture of sand, gravel and cement. Thus, there is not only the destruction of lumpy, sticky components of the raw materials, but also active uniform distribution of particles of cement, sand and gravel into a homogenous mass. The implementation of the proposed technology and equipment ensures not only reduction of the dimensions of the mixer length, but also improving the quality of finished products, as well as potential cement savings of 3-5%

    Aircraft loss of control (LOC) is a leading cause of fatal accidents across all transport airplane and operational classes. LOC can result from a wide spectrum of precursors (or hazards), often occurring in combination. Technologies developed for LOC prevention and recovery must therefore be effective under a wide variety of conditions and uncertainties, including multiple hazards, and the validation process must provide a means of assessing system effectiveness and coverage of these hazards. This paper provides a detailed description of a methodology for analyzing LOC as a dynamics and control problem for the purpose of developing effective technology solutions. The paper includes a definition of LOC based on several recent publications, a detailed description of a refined LOC accident analysis process that is illustrated via selected example cases, and a description of planned follow-on activities for identifying future potential LOC risks and the development of LOC test scenarios. Some preliminary considerations for LOC of Unmanned Aircraft Systems (UAS) and for their safe integration into the National Airspace System (NAS) are also discussed.

    Full Text Available The theory that is presented below aims to conceptualise how a group of undergraduate students tackle non-routine mathematical problems during a problem-solving course. The aim of the course is to allow students to experience mathematics as a creative process and to reflect on their own experience. During the course, students are required to produce a written ‘rubric’ of their work, i.e., to document their thoughts as they occur as well as their emotionsduring the process. These ‘rubrics’ were used as the main source of data.Students’ problem-solving processes can be explained as a three-stage process that has been called ‘solutioning’. This process is presented in the six sections below. The first three refer to a common area of concern that can be called‘generating knowledge’. In this way, generating knowledge also includes issues related to ‘key ideas’ and ‘gaining understanding’. The third and the fourth sections refer to ‘generating’ and ‘validating a solution’, respectively. Finally, once solutions are generated and validated, students usually try to improve them further before presenting them as final results. Thus, the last section deals with‘improving a solution’. Although not all students go through all of the stages, it may be said that ‘solutioning’ considers students’ main concerns as they tackle non-routine mathematical problems.

    In order to mitigate the potential effects on the human health which are associated to the use of treated wastewater in agriculture, antibiotic resistance genes (ARGs) are required to be carefully monitored in wastewater reuse processes and their spread should be prevented by the development of efficient treatment technologies. Objective of this study was the assessment of ARGs reduction efficiencies of a novel technological treatment solution for agricultural reuse of municipal wastewaters. The proposed solution comprises an advanced biological treatment (Sequencing Batch Biofilter Granular Reactor, SBBGR), analysed both al laboratory and pilot scale, followed by sand filtration and two different disinfection final stages: ultraviolet light (UV) radiation and peracetic acid (PAA) treatments. By Polymerase Chain Reaction (PCR), the presence of 9 ARGs (ampC, mecA, ermB, sul1, sul2, tetA, tetO, tetW, vanA) were analysed and by quantitative PCR (qPCR) their removal was determined. The obtained results were compared to the reduction of total bacteria (16S rDNA gene) and of a faecal contamination indicator (Escherichia coli uidA gene). Only four of the analysed genes (ermB, sul1, sul2, tetA) were detected in raw wastewater and their abundance was estimated to be 3.4±0.7 x10(4) - 9.6±0.5 x10(9) and 1.0±0.3 x10(3) to 3.0±0.1 x10(7) gene copies/mL in raw and treated wastewaters, respectively. The results show that SBBGR technology is promising for the reduction of ARGs, achieving stable removal performance ranging from 1.0±0.4 to 2.8±0.7 log units, which is comparable to or higher than that reported for conventional activated sludge treatments. No reduction of the ARGs amount normalized to the total bacteria content (16S rDNA), was instead obtained, indicating that these genes are removed together with total bacteria and not specifically eliminated. Enhanced ARGs removal was obtained by sand filtration, while no reduction was achieved by both UV and PAA disinfection

    The basic principles of the method for heavy metals electroextraction from technological solutions and wastewater includes pretreating to remove Chromium-6 and high concentrations of heavy metals and periodically treating in a six-electrode bipolar cylindrical electroreactor made of non-conducting material to achieve lower accepted levels of impurities. Six cylindrical steel electrodes form two triode stacks and are fed with three-phase alternating current of commercial frequency (50-60 Hz), which can be pulsed. Each phase of the three-phase current is connected to three electrodes of one triode stack or in parallel to two triode stacks. The parallel connection of three-phase current to two triode stacks is performed so that the same phase of the three phase current is connected in parallel with each two opposite electrodes of six electrodes located along the periphery, or with two adjacent electrodes. A bipolar stationary aluminum electrode is situated in the inter-electrode space. In one of the embodiments, the bipolar electrode is made of a perforated heat-resistant plastic container filled with secondary aluminum and duralumin scrap. In another embodiment, the bipolar electrode of aluminum or duralumin scrap may be made without a perforated container and is placed in the inter-electrode space as a bulk scrap. In this case, to prevent shorts, each of six steel electrodes is placed in isolated perforated plastic shell with holes of 5 mm in diameter. Non-ferrous metals are extracted in a form of ferrite-chromites, and aluminates as well as hydroxyl salts deposited in the inter-electrode space without electrolysis deposits on electrodes. Deposits are separated from solution by known methods of filtration.

    The NASA Applied Sciences Program uses the term Solutions Network in the context of its Enterprise Architecture to describe the ability of different components of the enterprise to generate ideas for new ways to use NASA missions, research, and/or models in conjunction with operational decision-making processes (or decision support systems) to achieve a particular benefit to society. In this paper, we describe the development of an information technology infrastructure that will facilitate that ability. The two main components of this infrastructure are: the Research Projects Knowledge Base (RPKB); and the Partner Network Knowledge Base (PNKB). The RPKB aims to index all relevant NASA research result publications in a database that will be interoperable with the evolving NASA enterprise architecture system and will share relevant table space with it. In particular, fields from this system identifying relevant NASA missions, models, and data products will be used to cross-index the data collected on published results of research projects. Fields characterizing the research results based on the seven Earth-Sun system science focus areas and the twelve applications of national priority are included. In the course of developing the RPKB, novel uses of existing online databases and search tools have been developed. In addition, data mining tools are being developed for facilitating the location of candidate results and the indexing of relevant matches. The PNKB database will characterize the current network of NASA Earth-Sun system partners. This includes information on organizations and agencies funded by or partnered with NASA to conduct Earth-Sun system scientific research, technology, and applications projects. The relationships between NASA programs and project sponsors are also captured in this database. Both the PNKB and the RPKB will be integrated with an existing, evolving model of the NASA Earth Science Enterprise using an enterprise architecture modeling and

    A series of 12 analogues of the Cer transfer protein (CERT) antagonist HPA-12 with long aliphatic chains were prepared as their (1R,3S)-syn and (1R,3R)-anti stereoisomers from pivotal chiral oxoamino acids. The enantioselective access to these intermediates as well as their ensuing transformation relied on a practical crystallization-induced asymmetric transformation (CIAT) process. Sonogashira coupling followed by triple bond reduction and thiophene ring hydrodesulfurization (HDS) into the corresponding alkane moieties was then implemented to complete the synthetic routes delivering the targeted HPA-12 analogues in concise 4- to 6-step reaction sequences. Ten compounds were evaluated regarding their ability to bind to the CERT START domain by using the recently developed time-resolved FRET-based homogeneous (HTR-FRET) binding assay. The introduction of a lipophilic appendage on the phenyl moiety led to an overall 10- to 1000-fold enhancement of the protein binding, with the highest effect being observed for a n-hexyl residue in the meta position. The importance of the phenyl ring for the activity was indicated by the reduced potency of the 3-deoxyphytoceramide aliphatic analogues. The 1,3-syn stereoisomers were systematically more potent than their 1,3-anti analogues. In silico studies were used to rationalized these trends, leading to a model of protein recognition coherent with the stronger binding of (1R,3S)-syn HPAs.

    Full Text Available Geopolymeraization technology is recognized as a promising method for immobilization of heavy metals by the stabilization or solidification process. This process involves the chemical reaction of alumino-silicate oxides with highly alkaline activator yielding the new material with amorphous or semi-amorphous structure, called geopolymer. Fly ash and blast furnace slag were mainly used as a raw material for geopolymerization process. In this paper we have investigated the possibility of immobilization of Zn from electric arc furnace dust (EAFD through geopolymerization of fly ash and possibility of Zn2+ adsorption from waste waters using fly ash based geopolymers. Efficacy of Zn immobilization from electric arc furnace dust was evaluated by TCLP test while the immobilization of Zn2+ ions from the water solution was evaluated through the removal efficiency. The results have shown that geopolymerization process may successfully be used for immobilization of Zn by stabilization of EAFD and for production of low cost adsorbent for waste water treatment.

    Full Text Available Amid the conditions of increasingly fierce competition, retailers are doing their best to meet the demands of their customers as efficiently as possible. Through the ever-growing level of product availability they raise the quality of service, which is positively reflected not only on the growth in sales, but also customer satisfaction. In the opposite case, the out-ofstock problem emerges, affecting not only customers, but also retailers and their suppliers. Bearing in mind, that the causes of the given problem occur most frequently in the last metres of the supply chain, in this paper we investigated the effect of backroom size on product availability, depending on the retail format. For this purpose, we used moderated regression analysis on the sample of 80 fast moving consumer goods in retail stores located on the territory of the Republic of Serbia. The obtained results pointed to opposite movements in the smallest and the largest format. Whereas in superettes the out-of-stock level lowers with the increase in the backroom size, it tends to drop in hypermarkets. Therefore, we pointed to some in-store problems that cause product stock-outs in different store formats. In addition to indicating the potential causes of analyzed relations, this paper also presents certain operational and technological solutions related to their mitigation.

    2006-12-01

    Full Text Available Research into the behaviours manifested by the dyslexic condition has often focused upon younger dyslexic pupils and the lower-order skill difficulty in decoding and encoding. A surge in interest in the writing process has shifted the focus to higher-order skills, and a growing body of research is emerging within the higher education context (Hughes & Suritsky, 1994; McNaughton et al., 1997; Hatcher, 2001; Singleton & Aisbett, 2001; Farmer et al., 2002. Students are expected to be ‘expert' writers, and the mark of a good student is the ability to use writing as a tool for thinking. Drawing upon data from semi-structured interviews with undergraduate and postgraduate dyslexic students and their real-time writing logs, three case studies are presented and used to explore creative ways of using technology to manage dyslexia. The students demonstrate how they use different types of software to overcome writing anxiety, ‘fear of the blank page' syndrome and issues of plagiarism. The experiences of the students within the case studies demonstrate that often simple software can provide the best solutions, and that students combine features from software programs in creative ways to compensate for weaknesses in their cognitive profile.

    The number of wearable wireless sensors is expected to grow to 400 million by the year 2014, while the number of operational mobile subscribers has already passed the 5.2 billion mark in 2011. This growth results in an increasing number of mobile applications including: Machine-to-Machine (M2M) communications, Electronic-Health (eHealth), and Mobile-Health (mHealth). A number of emerging mobile applications that require 3G and 4G mobile networks for data transport relate to telemedicine, including establishing, maintaining, and transmitting health-related information, research, education, and training. This review paper takes a closer look at these applications, specifically with regard to the healthcare industry and their underlying link technologies. The authors believe that the BlackBerry platform and the associated infrastructure (i.e., BlackBerry Enterprise Server) is a logical and practical solution for eHealth, mHealth, sensor and M2M deployments, which are considered in this paper.

    Solid solution nitriding technologies of 15Cr-7.5Mn-2.6Mo duplex stainless steel were investigated by using of orthogonal tests. The results show that the best technology would be the processes of 1050℃× 2h + 1150℃× 3h +1050℃× 2h + 1150℃× 4h under pure N2 with PN2=0.15MPa. The high nitrogen austenitic case with the depth of1.62mm can be obtained. Orthogonal tests show that the type of atmosphere has the most notable effect on solid solution nitriding process; the pressure in the furnace and the nitriding processes has a notable effect. X-ray diffraction analyses results indicate that the main phases in the cases of the solution-nitrided samples cooled in the furnace are high nitrogen austenite, CrN, Fe3O4 and nitrogen containing ferrite. In the other samples experienced solid solution nitriding and solution treatment the obtained phase in the cases is high nitrogen austenite only. The results show that solid solution nitriding is a process that nitrogen absolutely diffuses in the austenite. The diffusing activation energy in the conditions of PN2 = 0.15MPa and 1050℃~ 1200℃ is 186.6K J/mol.

    The signature in the proposal lies with the NSSS (Nuclear Systems Soft Solutions). NSSS proposed in the 3-dimensional space and time plus cost coordinates, i.e. 4{sup +} dimensional technology, is the backbone of digital engineering in the nuclear system design and management. The NSSS is empowered by Janus (Junctional Analysis Neo dynamic Unit Soft Power), NOTUS (Neo systemic Optimization Technical Unit Soft Power), Venus (Virtual Engineering Neo cybernetic Unit Soft Power), EURUS (Engineering Utilities Research Unit Soft Power) and INUUS (Informative Neo graphic Utilities Unit Soft Power). Janus extracts the geometric data directly from the computer-aided design CAD files to import to multidimensional computational fluid and structural dynamics codes. Janus uses the joint-CAD analysis methods to eliminate the necessity of any pre- and post- processors. Starting from the 3-dimensional CAD, NOTUS contributes to reducing the construction cost of the nuclear power plants by optimizing the component manufacturing procedure and the plant construction process. Planning and scheduling construction projects can thus benefit greatly by integrating traditional management techniques with digital process simulation visualization. The 3-dimensional visualization of construction processes and resulting products intrinsically afford most of the advantages realized by the 4{sup +}D technology. Problems with equipment positioning and manpower congestion in certain areas can readily be visualized prior to the actual operation, thus preventing accidents and safety problems such as collision between two machines and losses in productivity. Venus applied the virtual reality technology in nuclear industry. Virtual reality provides an interactive real time motion with sound and tactile and other forms of feedback. The management and workers can thus comprehend the work process crystal clear by visualizing precisely how activities relate to one another, whereby reducing conflicting

    A novel process for the wet cleaning of GaAs surface is presented. It is designed for technological simplicity and minimum damage generated within the GaAs surface. It combines GaAs cleaning with three conditions consisting of (1) removal of thermodynamically unstable species and (2) surface oxide layers must be completely removed after thermal cleaning, and (3) a smooth surface must be provided. Revolving ultrasonic atomization technology is adopted in the cleaning process. At first impurity removal is achieved by organic solvents; second NH4OH:H2O2:H2O = 1:1:10 solution and HCl: H2O2:H2O = 1:1:20 solution in succession to etch a very thin GaAs layer, the goal of the step is removing metallic contaminants and forming a very thin oxidation layer on the GaAs wafer surface; NH4OH:H2O = 1:5 solution is used as the removed oxide layers in the end. The effectiveness of the process is demonstrated by the operation of the GaAs wafer. Characterization of the oxide composition was carried out by X-ray photoelectron spectroscopy. Metal-contamination and surface morphology was observed by a total reflection X-ray fluorescence spectroscopy and atomic force microscope. The research results show that the cleaned surface is without contamination or metal contamination. Also, the GaAs substrates surface is very smooth for epitaxial growth using the rotary ultrasonic atomization technology.

  9. Selective removal/recovery of RCRA metals from waste and process solutions using polymer filtration{trademark} technology

    Energy Technology Data Exchange (ETDEWEB)

    Smith, B.F. [Los Alamos National Lab., NM (United States)

    1997-10-01

    Resource Conservation and Recovery Act (RCRA) metals are found in a number of process and waste streams at many DOE, U.S. Department of Defense, and industrial facilities. RCRA metals consist principally of chromium, mercury, cadmium, lead, and silver. Arsenic and selenium, which form oxyanions, are also considered RCRA elements. Discharge limits for each of these metals are based on toxicity and dictated by state and federal regulations (e.g., drinking water, RCRA, etc.). RCRA metals are used in many current operations, are generated in decontamination and decommissioning (D&D) operations, and are also present in old process wastes that require treatment and stabilization. These metals can exist in solutions, as part of sludges, or as contaminants on soils or solid surfaces, as individual metals or as mixtures with other metals, mixtures with radioactive metals such as actinides (defined as mixed waste), or as mixtures with a variety of inert metals such as calcium and sodium. The authors have successfully completed a preliminary proof-of-principle evaluation of Polymer Filtration{trademark} (PF) technology for the dissolution of metallic mercury and have also shown that they can remove and concentrate RCRA metals from dilute solutions for a variety of aqueous solution types using PF technology. Another application successfully demonstrated is the dilute metal removal of americium and plutonium from process streams. This application was used to remove the total alpha contamination to below 30 pCi/L for the wastewater treatment plant at TA-50 at Los Alamos National Laboratory (LANL) and from nitric acid distillate in the acid recovery process at TA-55, the Plutonium Facility at LANL (ESP-CP TTP AL16C322). This project will develop and optimize the PF technology for specific DOE process streams containing RCRA metals and coordinate it with the needs of the commercial sector to ensure that technology transfer occurs.

    There is a recognized need to develop information technology for the delivery of care services to older adults. However, little attention has been paid to the design of information technology for the oldest old demographic. We made novel use of data from observations, focus groups and cluster analysis of oldest old participant characteristics from a pilot study in a community setting to iteratively construct personas for the design of information technology for the oldest old. The resulting two personas, "Hazel" and "Rose", capture different abilities of members of the oldest old demographic group. In addition, we provide a list of eleven design recommendations to guide the design of technology that supports the abilities of people like Hazel and Rose. The resulting personas, design recommendations and persona construction method can be useful tools for informaticians and designers of new systems for the oldest old.

    Auto-stereoscopic 3D displays capable of high quality, full-resolution images for multiple users can only be created with time-sequential systems incorporating eye tracking and a dedicated optical design. The availability of high speed displays with 120Hz and faster eliminated one of the major hurdles for commercial solutions. Results of alternative display solutions from SeeReal show the impact of optical design on system performance and product features. Depending on the manufacturer's capabilities, system complexity can be shifted from optics to SLM with an impact on viewing angle, number of users and energy efficiency, but also on manufacturing processes. A proprietary solution for eye tracking from SeeReal demonstrates that the required key features can be achieved and implemented in commercial systems in a reasonably short time.

    Full Text Available The investigations of thermal and technical features of enveloping structures show that at the present time the structures of outer walls with hinged ventilated facades are the most energy efficient. The facades with air space are widely used both in residential and in public buildings. In the recent years the problems related to energy efficient enveloping structures are being actively investigated. The problems of modern Russian and foreign energy-efficient facade systems, their technical and structural solutions and the main methods of their installation are reviewed in the article. The methods of solving the tasks of research are proposed and the obtained results are described. The development of organizational and technological solutions for sealing of joints of front panels during installation of ventilated facades by pre-assembly method was the basis of the method of solving of the problem. The obtained data together with the developed structural and technological solutions may become the base for the development of technical rules and regulations.

    The Department of Energy (DOE) faces unique challenges in characterizing and handling its mixed wastes. Mixed waste is low-level or transuranic (TRU) contaminated wastes containing Resource Conservation and Recovery Act (RCRA) hazardous materials. Characterization and material handling technologies will be required to solve pretreatment and disposal needs, and to meet transportation requirements. The Mixed Waste Focus Area (MWFA) will fund the development and demonstration of characterization and material handling technologies to ensure the availability to support the DOE mixed waste needs. The MWFA will be evaluating commercially available and laboratory developed technologies for applicability in meeting these needs. Improved systems will be developed, on the commercial or laboratory side, as needed to address unmet needs. Studies/demonstrations are taking place this year to evaluate the capabilities of existing systems and identify technology gaps. Calls for proposals will be made to both industry and laboratory to identify work to address those gaps. Prioritization of applicable proposals will take place and activities funded appropriately to address characterization and material handling needs.

Nevertheless, our team have unambiguously proved that the TC generates the inerton field, which is associated with a substructure of the matter waves (and, therefore, it does not relate to the electromagnetic nature.

    Numerous studies indicate that target gene silencing by RNA interference (RNAi)could lead to insect death.This phenomenon has been considered as a potential strategy for insect pest control,and it is termed RNAi-mediated crop protection.However,there are many limitations using RNAi-based technology for pest control,with the effectiveness target gene selection and reliable double-strand RNA(dsRNA)delivery being two of the major challenges.With respect to target gene selection,at present,the use of homologous genes and genome-scale high-throughput screening are the main strategies adopted by researchers.Once the target gene is identified,dsRNA can be delivered by micro-injection or by feeding as a dietary component.However,micro-injection,which is the most common method,can only be used in laboratory experiments.Expression of dsRNAs directed against insect genes in transgenic plants and spraying dsRNA reagents have been shown to induce RNAi effects on target insects.Hence,RNAi-mediated crop protection has been considered as a potential new-generation technology for pest control,or as a complementary method of existing pest control strategies;however,further development to improve the efficacy of protection and range of species affected is necessary.In this review,we have summarized current research on RNAi-based technology for pest insect management.Current progress has proven that RNAi technology has the potential to be a tool for designing a new generation of insect control measures.To accelerate its practical application in crop protection,further study on dsRNA uptake mechanisms based on the knowledge of insect physiology and biochemistry is needed.

Hence, RNAi-mediated crop protection has been considered as a potential new-generation technology for pest control, or as a complementary method of existing pest control strategies; however, further development to improve the efficacy of protection and range of species affected is necessary. In this review, we have summarized current research on RNAi-based technology for pest insect management. Current progress has proven that RNAi technology has the potential to be a tool for designing a new generation of insect control measures. To accelerate its practical application in crop protection, further study on dsRNA uptake mechanisms based on the knowledge of insect physiology and biochemistry is needed.

    2004-01-01

    Technical limitations, mostly related to the issue of time delay for transmission of digitized information, had prevented the development of remote surgery intended as performance of a complete surgical procedure from long distances. To overcome the issue of time delay, tests and researches performed with the joined effort of surgeons, robotic and telecommunication engineers convinced our group that use of the high-speed terrestrial network [asynchronous transfer mode (ATM) service], rather than satellite connections, would significantly reduce the time lag for transmission of data. Using ATM technology, our group demonstrated the feasibility of performing surgery across transoceanic distances by safely carrying out a laparoscopic cholecystectomy, first on an animal model and later (September 7, 2001), on a patient. Using ATM technology, the mean time lag for transmission of data and images was 155 msec despite a total round-trip distance of 14,000 km. Teletransmission of active surgical manipulations have the potential to ensure availability of surgical expertise in remote locations for difficult or rare operations, and improve surgical training worldwide. However, several limitations remain for remote surgery to become commonplace. Among these, the need to render ATM network available to hospitals, costs of technology, ethical and liability issues, and possible conflicts of jurisdictions between countries involved.

    Nutritive Sucking (NS) is a highly organized process that is essential for infants' feeding during the first six months of their life. It requires the complex coordination of sucking, swallowing and breathing. The infant's inability to perform a safe and successful oral feeding can be an early detector of immaturity of the Central Nervous System (CNS). Even though the importance of early sucking measures has been confirmed over the years, the need for standardized instrumental assessment tools still exists. Clinicians would benefit from specifically designed devices to assess oral feeding ability in their routine clinical monitoring and decision-making process. This work is a review of the main instrumental solutions developed to assess an infant's NS behavior, with a detailed survey of the main quantities and indices measured and/or estimated to characterize sucking behavior skills and their development. The adopted sensing measuring systems will be described, and their main advantages and weaknesses will be discussed, taking into account their application to clinical practice, or to at-home monitoring as post-discharge assessment tools. Finally, the study will highlight the most suitable sensing solutions and give some prompts for further research.

  4. Simple solution : VAC-Screen technology helps drillers recapture oil-based mud

    Energy Technology Data Exchange (ETDEWEB)

    Wells, P.

    2010-11-15

    Calgary-based FP Marangoni Inc. has developed a VAC-Screen drilling fluid recovery system that improves the efficiency and environmental performance of oil production operations. With 8 patents filed, FP Marangoni is currently the only oilfield service company in the world that has successfully established a way to blend vacuum and rig shakers to recapture oil-based mud, or any drilling fluid. The VAC-Screen system is now being used by many operators and has the potential to be used across a wide spectrum of drilling applications. The system gives operators a considerable advantage in meeting progressively more stringent environmental regulations for cuttings disposal. The genesis for the system began while the company was working in the Alberta Foothills and a client was losing drilling fluids off of the ends of shakers. A rotary vacuum dryer fluid recovery and cuttings drying system was ruled out for solving the problem because it would degrade the drilling cuttings. FP Marangoni initially opted for blowing mud through the shaker screen using compressed air and air knife drying systems, but the high velocity air created a fine mud mist which created a health hazard. FP Marangoni then opted to build a vacuum manifold, placed it underneath the shaker screen and attached it to the rig vacuum. This method dried the cuttings as hoped, but they froze right on the shaker screen. These issues were sorted out with some fine-tuning and the company was eventually able to run the VAC-Screen technology on any size of shaker screen. The fluid that comes out of the end of the shaker flows onto the vacuum manifolds where it is then recovered and the cuttings dry out. The newly-created design incorporates a processing area which ensures the cuttings are dried out efficiently and are easy to dispose of. A prototype VAC-Screen was run over a three-month period from February through April 2010, and the technology was commercially introduced in June 2010. The VAC-Screen technology is

    Condensing boiler technology has been around for many years and has proven to be a durable, reliable method of heating. Based on previous research efforts, however, it is apparent that these types of systems are not designed and installed to achieve maximum efficiency. For example, in order to protect their equipment in the field, manufacturers of low-mass condensing boilers typically recommend design strategies and components that ensure steady, high flow rates through the heat exchangers, such as primary-secondary piping, which ultimately result in decreased efficiency. There is also a significant lack of information for contractors on how to configure these systems to optimize overall efficiency. In response to these findings, researchers from Building America team Consortium for Advanced Residential Buildings worked with industry partners to develop hydronic system designs that would address these issues and result in higher overall system efficiencies and improved response times.

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

    Design is often found as one of the contributing factors in accident in the nuclear industry. The design of new technological systems and organisational structures has to take into account and be driven by the future users' needs and has to consider how their role and work practices within the organisation will be affected. The SADE project explores to which extend the concepts of safety culture and resilience engineering can contribute to the prevention of design errors when no hindsight data are available. In 2011, the SADE project focused on gathering experience and clarifying the current issues and challenges related to the design process. During 2011 seventeen interviews have been conducted in Finland and Sweden to identify some of the major challenges the nuclear industry is currently facing. At the same time a literature review has been conducted to establish a sound common theoretical ground. This progress report presents some of the relevant theoretical findings and preliminary results from the interviews. (Author)

Excess concentration of heavy metals causes harmful affect and alters the physicochemical characteristics of surrounding environmental parameters. Copper is an important heavy metal present in the aquatic environment, including wide industrial applications, and is an essential factor in animal metabolism. To recover and reduce copper concentration from aqueous medium an attempted has been made with membrane technology. In this research work ultra filtration, nano filtration and reserve osmosis have been used. At optimum conditions 4.49 g/L initial concentration, 0.72 m3/h inlet flow rate, 40 bar working pressure were obtained for maximum recovery (40.977 g/min of copper at pH 6.8 with reverse osmosis. To achieve this, 27 experimental runs were developed according to central composite design and analysed. The value of R2 > 0.91 for the obtained quadratic model indicates the high correlation between observed or the experimental value of response and response value predicted by the mathematical model. This implies that the experimental data correlated very well with the quadratic model chosen for the analysis.

    2012-10-01

    The activities of the oil industry have several impacts on the environment due to the large amounts of oily wastes that are generated. The oily sludges are a semi-solid material composed by a mixture of clay, silica and iron oxides contaminated with oil, produced water and the chemicals used in the production of oil. Nowadays both the treatment and management of these waste materials is essential to promote sustainable management of exploration and exploitation of natural resources. Biological, physical and chemical processes can be used to reduce environmental contamination by petroleum hydrocarbons to acceptable levels. The choice of treatment method depends on the physical and chemical properties of the waste as well as the availability of facilities to process these wastes. Literature provides some operations for treatment of oily sludges, such as landfilling, incineration, co-processing in clinkerization furnaces, microwave liquefaction, centrifugation, destructive distillation, thermal plasma, low-temperature conversion, incorporation in ceramic materials, development of impermeable materials, encapsulation and biodegradation in land farming, biopiles and bioreactors. The management of the technology to be applied for the treatment of oily wastes is essential to promote proper environmental management, and provide alternative methods to reduce, reuse and recycle the wastes.

  1. ICS logging solution for network-based attacks using Gumistix technology

    Science.gov (United States)

    Otis, Jeremy R.; Berman, Dustin; Butts, Jonathan; Lopez, Juan

    2013-05-01

    Industrial Control Systems (ICS) monitor and control operations associated with the national critical infrastructure (e.g., electric power grid, oil and gas pipelines and water treatment facilities). These systems rely on technologies and architectures that were designed for system reliability and availability. Security associated with ICS was never an inherent concern, primarily due to the protections afforded by network isolation. However, a trend in ICS operations is to migrate to commercial networks via TCP/IP in order to leverage commodity benefits and cost savings. As a result, system vulnerabilities are now exposed to the online community. Indeed, recent research has demonstrated that many exposed ICS devices are being discovered using readily available applications (e.g., ShodanHQ search engine and Google-esque queries). Due to the lack of security and logging capabilities for ICS, most knowledge about attacks are derived from real world incidents after an attack has already been carried out and the damage has been done. This research provides a method for introducing sensors into the ICS environment that collect information about network-based attacks. The sensors are developed using an inexpensive Gumstix platform that can be deployed and incorporated with production systems. Data obtained from the sensors provide insight into attack tactics (e.g., port scans, Nessus scans, Metasploit modules, and zero-day exploits) and characteristics (e.g., attack origin, frequency, and level of persistence). Findings enable security professionals to draw an accurate, real-time awareness of the threats against ICS devices and help shift the security posture from reactionary to preventative.

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

    Science.gov (United States)

    Youngblut, Christine

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

    As a consequence of their growing use in electronic and industrial products, increasing amounts of technology critical elements (TCEs) are being released to the environment. Currently little is known about the fate of many of these elements. Initial research on their potential environmental impact identifies TCEs as emerging contaminants. TCE movement in the environment is often governed by water systems. Research on "natural" waters so far demonstrates that TCEs tend to be associated with suspended particulate matter (SPM), which influences TCE aqueous concentrations (here: concentration of TCEs in dissolved form and attached to SPM) and transport. However, the relative potential of different types of SPM to interact with TCEs is unknown. Here we examine the potential of various types of particulate matter, namely different nanoparticles (NPs; Al2O3, SiO2, CeO2, ZnO, montmorillonite, Ag, Au and carbon dots) and humic acid (HA), to impact TCE aqueous concentrations in aqueous solutions with soil and sand, and thus influence TCE transport in soil-water environments. We show that a combination of NPs and HA, and not NPs or HA individually, increases the aqueous concentrations of TCEs in soil solutions, for all tested NPs regardless of their type. TCEs retained on SPM, however, settle with time. In solutions with sand, HA alone is as influential as NPs+HA in keeping TCEs in the aqueous phase. Among NPs, Ag-NPs and Au-NPs demonstrate the highest potential for TCE transport. These results suggest that in natural soil-water environments, once TCEs are retained by soil, their partitioning to the aqueous phase by through-flowing water is unlikely. However, if TCEs are introduced to soil-water environments as part of solutions rich in NPs and HA, it is likely that NP and HA combinations can increase TCE stability in the aqueous phase and prevent their retention on soil and sand, thus facilitating TCE transport.

    exposes all interns to a larger spectrum of research topics and approaches within a field than would be available within a single research site. Evaluations also reveal that fostering social and academic interactions among interns working on generally unrelated projects at separate locations is challenging and requires a consistent, focused effort by the program. In part this is because creating a cohort experience in this situation requires a layer of interaction beyond the networks naturally establish by the interns when co-located. A critical first step is to establish a social presence among the group. This occurs through early face-to-face meetings and then is carried forward as interns transition to virtual interactions. These virtual interactions occur through a variety of technological solutions. Both commercially and freely available technologies such as blogging software, Facebook, an online course management system, virtual worlds, and a variety of online conferencing applications are used to connect the students both synchronously and asynchronously. We have documented the strengths and weaknesses of these individual solutions and show how combinations, combined with programmatic interventions, can offer a suite of functionality necessary to facilitate both social and academic interactions and influence career paths.

    Full Text Available Nowadays there is a significant increase of the incidence of left-handedness and sinistrality among schoolchildren. Theydemonstrate a large number of left-sided motor and sensory preferences which are considered as external markers offunctional hemispheric asymmetry of the brain. The purposes of this study are to investigate gender peculiarities and specificityof age-related dynamics of laterality pattern’s formation in junior schoolchildren and to find out educational peculiarities anddifficulties of left-handed children. The findings show that left-handers differ greatly in their mental development by havingsome peculiarities of intelligence, world’s perception and prevailing thinking strategies, ways of memorization, specificity ofemotional-affective expression. The main problems of left-handed children in school performance are academic failure, lack ofperseverance, anxiety neurosis, and extreme emotional lability. Integrated development of the left hemisphere and the righthemisphere thinking of left-handed schoolchildren is a favorable condition for harmonious personal and intellectualdevelopment and effective mastering of various modules of the school curriculum. The technological solution of the problem ofteaching the children with left-sided laterality is to include in educational programs some special exercises to developimagination, emotional sensitivity, integrity of perception, global view to the problems, creativeness, and original approachesto tasks’ solving. So a complex program for the intensive development of the right hemisphere of children who demonstrateleft-sided laterality to overcome the possible failure at primary school is proposed in this paper.

    The drilling of deep wells in the La Primavera caldera has evidenced a highly complex and hazardous problematic situation due to considerable losses of drilling fluids. Such large losses have not occurred in any other geothermal field in the world. These losses are due mainly to the structural conditions of the geological formations which are penetrated. The technology employed in the construction of deep wells has played a very important role in the solution to these problems. Field case histories describe the effectiveness of the developments of drilling fluids and cement materials in cavernous formations with severe lost-circulation problems. A processed clay bentonite was developed whose high performance and rapid hydration characteristics allowed a reduction of up to 5 hours in the drilling fluid conditioning time. Also, useful results were obtained through the development of a granular plugging mixture which maintained sealing properties at 70 kg/cm 2 under cavernous simulated conditions. This granular plugging mixture kept losses of the volume of drilling fluid under 8% with respect to the total volume. Special cement plugs with thixotropic behavior allowed the handling and placement of this slurry in the problematic zone. The CaSO 4 addition to the cement slurry was optimized so that a placement time of 30 min could be obtained. Additionally, the mechanical compressive strength values of this special cement plug ranged from 50 to 100 kg/cm 2.

    On the Norwegian sector of the North-Sea the oil- and gas-producing fields Troll B and C are the main contributors to radium discharged to the sea (190 GBq/a {sup 226}Ra and 150 GBq/a {sup 228}Ra). Thus, to observe effects caused by the emission of radioactivity and to consider remedial action one should focus on these two installations. Both installations are now operated by Statoil. In a previous comprehensive study of the speciation of discharged radium the conclusion was that it is impossible to detect any effect from radiation doses. The incremental doses due to the emissions were found to be in the nSv-range. The study covered precipitation by sulfate in the sea water, absorption on organic and inorganic materials, uptake in cod eggs and in juvenile cod, effect on sediment living organisms, background levels of pelagic fish and in sediments, and modeling of the distribution in the water column as well the distribution along the coastal stream. Despite the lack of radiation effects, an assessment of possible technological solution for removal of the radium has been undertaken. Such methods must meet the severe requirements imposed by the oil recovery process at Troll B and C: High produced water rates (>1000 m{sup 3}/h), high salinity and content of water soluble carboxylic acids originating from the crude oil, in addition to a relatively high content of barium (3 550 tonnes/a). For implementation on an offshore installation the footprint and weight of the equipment would have to be as low as possible. It is also imperative that the radiation doses to operators are as low as possible. This puts strict requirements on the shielding of the absorbents accumulating {sup 226}Ra and {sup 228}Ra. No commercially available methods were identified, but one new conceptual method based on absorption of radium on barite has been proposed. Barite is also a good shielding material. Tests performed at Institute for Energy Technology show, however, that the kinetics of the

    2010-04-01

    The study of the adoption of information technology (IT) by individuals has taken two approaches, one emphasizing rationalistic goal-oriented behavior and the other focusing on poignant forces that influence an individual's reaction to a new IT. These approaches are not necessarily mutually exclusive. Individuals' acceptance and subsequent usage of a new IT is predicated on both. Additionally, the tendency in past studies has been to examine either the rational or the poignant factors in the context of a "resource-rich" environment-one in which there is an abundance of IT, adequate infrastructure, and a high level of acculturation to technology solutions. Consequently, there is a clear need for the examination of these factors in resource-poor environments, where assumptions on technology abundance and technology culturation do not hold. We empirically test a model that explains the intention of physicians in a resource-poor environment (epitomized by rural Ethiopia) to adopt telemedicine systems. This model integrates the rational factors driving goal-oriented behavior with the poignant/emotive factors that are an innate part of each adopter's reaction to the new technology. We use the model to expose salient contextual factors that explain the acceptance behavior of individuals toward complex information and communications technology (ICT) solutions and implications of these on the management of technology transfer initiatives in a resource-poor environment. The model is parsimonious, yet explains 28% of the variance in the intention to adopt telemedicine systems and 58% in perceived ease of use. The theoretical and practical implications of this model are discussed. Namely, Sub-Saharan African, in general, and Ethiopian culture, in particular, plays an integral role in the adoption of ICT solutions. Organizational positions and roles among physicians, clinical professionals, and superiors stand to impact the adoption of telemedicine and other healthcare

  1. How to Assess Market Readiness for an Innovative Solution: The Case of Heat Recovery Technologies for SMEs

    Directory of Open Access Journals (Sweden)

    Sune Solberg Hjorth

    2016-11-01

    Full Text Available The uptake of solutions that increase energy efficiency is significantly lower for small- and medium-sized enterprises (SMEs. This is due to several barriers, among which legislation, motivation, finance and other resources play a large role. In this paper, we describe a framework of market readiness and use it to assess the asymmetry between existing solutions and opportunities in the market. The aim is to identify which steps can be taken in order to introduce more energy optimizations into SMEs, and who should be taking those steps. More specifically, we explore how four Danish SMEs, in different parts of the value chain in the food processing industry, view energy efficiency improvements, focusing on the potential reuse of waste heat, along with what they consider important for taking on such projects. The findings show that while the companies operate very differently, they share common motivations and barriers when it comes to energy efficiency. Based on these findings, this paper argues that the biggest advancements are not to be made within the SMEs, but partly through the legislation that affects the financial benefits of energy improvement solutions, and through the marketing approach that solution suppliers take towards their potential customers when addressing the inherently individual needs of SMEs.

    The new device architectures and materials being introduced for sub-10nm manufacturing, combined with the complexity of multiple patterning and the need for improved hotspot detection strategies, have pushed current wafer inspection technologies to their limits. In parallel, gaps in mask inspection capability are growing as new generations of mask technologies are developed to support these sub-10nm wafer manufacturing requirements. In particular, the challenges associated with nanoimprint and extreme ultraviolet (EUV) mask inspection require new strategies that enable fast inspection at high sensitivity. The tradeoffs between sensitivity and throughput for optical and e-beam inspection are well understood. Optical inspection offers the highest throughput and is the current workhorse of the industry for both wafer and mask inspection. E-beam inspection offers the highest sensitivity but has historically lacked the throughput required for widespread adoption in the manufacturing environment. It is unlikely that continued incremental improvements to either technology will meet tomorrow's requirements, and therefore a new inspection technology approach is required; one that combines the high-throughput performance of optical with the high-sensitivity capabilities of e-beam inspection. To support the industry in meeting these challenges SUNY Poly SEMATECH has evaluated disruptive technologies that can meet the requirements for high volume manufacturing (HVM), for both the wafer fab [1] and the mask shop. Highspeed massively parallel e-beam defect inspection has been identified as the leading candidate for addressing the key gaps limiting today's patterned defect inspection techniques. As of late 2014 SUNY Poly SEMATECH completed a review, system analysis, and proof of concept evaluation of multiple e-beam technologies for defect inspection. A champion approach has been identified based on a multibeam technology from Carl Zeiss. This paper includes a discussion on the

An alignment system based on atmospherical dispersion, called a dispersometer, is a metrological solution to the atmospherically induced limitations, in optical alignment and direction observations of high accuracy. In the dispersometer we are using the dual-wavelength method for dispersive air to obtain refraction compensated angle measurements, the detrimental impact of atmospheric turbulence notwithstanding. The principle of the dual-wavelength method utilizes atmospherical dispersion, i.e. the wavelength dependence of the refractive index. The difference angle between two light beams of different wavelengths, which is called the dispersion angle {delta}{beta}, is to first approximation proportional to the refraction angle: {beta}{sub IR} {nu}({beta}{sub blue} - {beta}{sub IR}) = {nu} {delta}{beta}, this equation implies that the dispersion angle has to be measured at least 42 times more accurate than the desired accuracy of the refraction angle for the wavelengths used in the present dispersometer. This required accuracy constitutes one major difficulty for the instrumental performance in applying the dispersion effect. However, the dual-wavelength method can only be successfully used in an optimized transmitter-receiver combination. Beyond the above mentioned resolution requirement for the detector, major difficulties in instrumental realization arise in the availability of a suitable dual-wavelength laser light source, laser light modulation with a very high extinction ratio and coaxial emittance of mono-mode radiation at both wavelengths. Therefore, this paper focuses on the solutions of the dual-wavelength transmitter introducing a new hardware approach and a complete re-design of

    Full Text Available The combustion of coal wastes resulting from mining is of particular environmental concern, and the importance of proper management involving real-time assessment of their status and identification of probable evolution scenarios is recognized. Continuous monitoring of the combustion temperature and emission levels of certain gases allows for the possibility of planning corrective actions to minimize their negative impact on the surroundings. Optical fiber technology is well suited to this purpose and here we describe the main attributes and results obtained from a fiber optic sensing system projected to gather data on distributed temperature and gas emissions in these harsh environments.

    The use of flat tile technology to handle heat fluxes in the range of 20 MW/m{sup 2} with components relevant for fusion experiment applications is technically possible with the hypervapotron cooling concept. This paper deals with recent high heat flux performances operated with success on 2 identical mock-ups, based on this concept, that were tested in 2 different electron gun facilities. Each mock-up consisted of a CuCrZr heat sink armored with 25 flat tiles of the 3D carbon fibre composite material SEPcarb NS31 assembled with pure copper by active metal casting (AMC). The AMC tiles were electron beam welded on the CuCrZr bar, fins and slots on the neutral beam JET design were machined into the bar, then the bar was closed with a thick CuCrZr rear plug including hydraulic connections then the bar was electron beam welded onto the sidewalls. The testing results show that full ITER design specifications were achieved with margins, the critical heat flux limit was even higher than 30 MW/m{sup 2}. These results highlight the high potential of this technology for ITER divertor application.

    Potable water has become a scarce resource in many countries. In fact, the world is not running out of water, but rather, the relatively fixed quantity is becoming too contaminated for many applications. Hence, the present work was designed to evaluate the desalination efficiency of resin and glass fiber-reinforced Polysulfone polymer-based monopolar and bipolar (BPM) ion exchange membranes (with polyvinyl pyrrolidone as the intermediate layer) on a real sample brine solution for 8 h duration. The prepared ion exchange membranes (IEMs) were characterized using FTIR, SEM, TGA, water absorption, and contact angle measurements. The BPM efficiency, electrical conductivity, salinity, sodium, and chloride ion concentration were evaluated for both prepared and commercial-based IEM systems. The current efficiency and energy consumption values obtained during BPMED process were found to be 45 % and 0.41 Wh for RPSu-PVP-based IEM system and 38 % and 1.60 Wh for PSDVB-based IEM system, respectively.

    People are more willing to accept and act on the science surrounding global environmental change when they can see themselves in that change - or when they can understand how global processes like climate change impact their lives in concrete and intimate ways. The digital revolution presents unique opportunities to make those sorts of connections. We will explore how new technologies can help to immerse users in the challenges of global sustainability and deepen their sense of personal involvement. We will draw on case studies from the Future Earth Media Lab, a communications and research initiative that was formed by Future Earth, the International Council for Science (ICSU) and Globaïa in 2015. The Media Lab was set up to bring together partners from science, technology, art and design to co-create products and experiences that can change the way we communicate the challenges of the world's most intractable problems, with the potential to shift mindsets and behaviours. We are at the very beginning of this 10-year project to explore how advances in virtual reality, augmented reality, data visualization and artificial intelligence will reshape how non-scientific audiences engage with science. The session will focus on results of the most recent projects launched in 2016: a hackathon series with the Iris.AI artificial intelligence project to test the limits of AI for searches based on framed research questions; a global hackathon series around using virtual reality to communicate global change challenges and an immersive space co-created with data visualization experts at the UN's biggest conference on sustainable urbanization at Quito, Ecuador.

    Full Text Available England and Australia have introduced new learning areas, teaching computer science to children from the first year of school. This is a significant milestone that also raises a number of big challenges: the preparation of teachers and the development of resources at a national scale. Curriculum change is not easy for teachers, in any context, and to ensure teachers are supported, scaled solutions are required. One educational approach that has gained traction for delivering content to large-scale audiences are massively open online courses (MOOCs; however, little is known about what constitutes effective MOOC design, particularly within professional development contexts. To prepare teachers in Australia, we decided to ride the wave of MOOCs, developing a MOOC to deliver free computing content and pedagogy to teachers with the integration of social media to support knowledge exchange and resource building. The MOOC was designed to meet teacher needs, allowing for flexibility, ad-hoc interactions, support and the open sharing of resources. In this paper, we describe the process of developing our initiative, participant engagement and experiences, so that others encountering similar changes and reforms may learn from our experience.

Access to energy is important basis of human existence, essential to the satisfaction of basic needs such as food, clothing, and housing and also of mobility and communication. However, the dependency world burning of fossil fuels for energy generation and supply of a demand constantly increasing, both in industrialized countries and those in development, already threatening the ecological stability of the Earth. At the same time, conflicts by distribution of the last reserves these resources non-renewable threaten significantly to civil society. Adding to the breakneck speed in which humanity consumes the energetic sources and the obvious devastation of nature has an unequal distribution in consumption and access to energy. Renewable sources and energy efficiency are viable and necessary, especially because they can be the key to reduce wastefulness and extend the access to energy. In this way, there is a significant influence on economic and social inclusion of population excluded, generating employment and income with costs local and global environmental reduced compared to traditional forms and unsustainable generation and use of energy. This work is a study involving issues related to rural electrification from hydroelectricity, especially related to those isolated communities of the Amazon region that are lacking this form of energy, presented a general review since the origins of hydroelectricity in Brazil, as well as a national panorama electric exclusion as well as a scenario Amazon's supply of electricity.

    Full Text Available The main thrust of this paper is to discuss the development of open and distance education in Nigeria and the major manifestations of the use of information and communication technologies (ICTs in education in open and distance learning. This study further discusses the importance and use of ICTs in open and distance learning in making education accessible to a larger population of students. From that vantage point this paper reviews the phenomenon of ICTs in open and distance learning in developing countries such as Nigeria. The paper identifies a number of issues that impede the effective optimization of ICTs in open and distance learning in developing countries. Prominent among the issues highlighted are poverty, intermittent supply of electricity and language barrier. The paper argues that these problems are to be tackled if the objective of enhancing the potentials of ICTs in open and distance learning in developing countries were to be achieved. On that note the current paper makes some humble suggestions on how to curtail the problems. The study employed descriptive method. An intact class of students that registered for the Bachelor of Education distance learning programme of the Faculty of Education of the Obafemi Awolowo University,Ile-Ife formed the samples used for the study. This was done to collect information on the factors affecting usage of ICT. The result shows that lack of skills rank highest (46.1%, following this is non availability of ICT at home (18.8%, costs (11.3% and non familiarity with ICT (10.6%.

    An increasing number of low-income countries (LICs) exhibit high rates of malnutrition coincident with rising rates of overweight and obesity. Individual-level dietary data are needed to inform effective responses, yet dietary data from large-scale surveys conducted in LICs remain extremely limited. This discussion paper first seeks to highlight the barriers to collection and use of individual-level dietary data in LICs. Second, it introduces readers to new technological developments and research initiatives to remedy this situation, led by the International Dietary Data Expansion (INDDEX) Project. Constraints to conducting large-scale dietary assessments include significant costs, time burden, technical complexity, and limited investment in dietary research infrastructure, including the necessary tools and databases required to collect individual-level dietary data in large surveys. To address existing bottlenecks, the INDDEX Project is developing a dietary assessment platform for LICs, called INDDEX24, consisting of a mobile application integrated with a web database application, which is expected to facilitate seamless data collection and processing. These tools will be subject to rigorous testing including feasibility, validation, and cost studies. To scale up dietary data collection and use in LICs, the INDDEX Project will also invest in food composition databases, an individual-level dietary data dissemination platform, and capacity development activities. Although the INDDEX Project activities are expected to improve the ability of researchers and policymakers in low-income countries to collect, process, and use dietary data, the global nutrition community is urged to commit further significant investments in order to adequately address the range and scope of challenges described in this paper.

    There is no doubt that the contribution of the Health Care Technologies to the tremendous evolution on Medicine since mid XX century has been one of its most important pillars. At the same time the innovation has been sometimes accused of been the root of the increase in the Health Care expenditure to support the Health of the society. Actually, when the Health Care Systems are focusing not only on the critical processes but on the continuum of the disease, the application of innovation to the chronic diseases and, more specifically, in the Cardiovascular ones (specially the Cardiac Insufficiency), represents a great challenge for care givers, patients and the Health Care Systems as their treatment requires continuous medical care and patient self management. The key for establishing this continuity of care in an efficient way is based in the concept of "Anticipation". This is the only way to avoid the burden of the continuous re-hospitalizations of this kind of patients. The engagement of patients in the adoption of healthy lifestyles with a positive impact in the progression of their diseases is fundamental to avoid the appearance of chronic complications or co-morbidities. Only with these assumptions the Innovation on Health Care Technologies will become part of the solution of the sustainability of the Health Care expenditure for the society. This paper present the keys for making the innovation efficient understanding the transversal of the Health Care processes.

    Full Text Available Sequencing the human genome began in 1994, and 10 years of work were necessary in order to provide a nearly complete sequence. Nowadays, NGS technologies allow sequencing of a whole human genome in a few days. This deluge of data challenges scientists in many ways, as they are faced with data management issues and analysis and visualization drawbacks due to the limitations of current bioinformatics tools. In this paper, we describe how the NGS Big Data revolution changes the way of managing and analysing data. We present how biologists are confronted with abundance of methods, tools, and data formats. To overcome these problems, focus on Big Data Information Technology innovations from web and business intelligence. We underline the interest of NoSQL databases, which are much more efficient than relational databases. Since Big Data leads to the loss of interactivity with data during analysis due to high processing time, we describe solutions from the Business Intelligence that allow one to regain interactivity whatever the volume of data is. We illustrate this point with a focus on the Amadea platform. Finally, we discuss visualization challenges posed by Big Data and present the latest innovations with JavaScript graphic libraries.

    Our Healthcare systems worldwide are facing grand challenges that can be addressed by intelligent, miniaturized and interconnected devices. Many of today's pharmaceutical drugs create bigger problems than solutions, as drugs help only 40% of the patients and kill, in the USA alone, over 100,000 people per year. The widespread use of antibiotics has led to new strands of bacteria that defy all known antibiotics and kill well over 100,000 people yearly in the world. Outbreaks of infections by new viruses and anti-resistant bacteria are expected with even more grave consequences. The quality of food around the world is steadily deteriorating, as the soils are becoming depleted of essential nutrients and contain increasing amounts of pesticides, herbicides and fungicides. Our environment is burdened with 2.5 billion tonnes of chemicals per year that accumulate in the soil, groundwater, rivers and seas, and eventually end up in our food and our drinking water. As a consequence, there is a strong increase in the incidence of diseases hardly known fifty years ago. In parallel, an increasing number of people are taking the responsibility for their health and well-being in their own hands and are looking for mobile and in-obtrusive ways to objectively monitor their health status. The development of intelligent, miniaturized systems, by the heterogeneous integration of technologies such as micro- and nano-electronics, photonics, biotechnology, materials and information & communication, addresses these issues and has received intensive public support in the EU over the past two decades in the FP6 and FP7 programs. Proven concepts and functional prototypes exist with the potential to create new opportunities to improve our healthcare systems, in particular personalized or precision medicine. These device concepts offer unique abilities to sense, detect, analyze, communicate, respond, and monitor phenomena from the macro (e.g. body, tissues) to the nano scale (e.g. molecules

    The August 2003 blackout of the northeastern U.S. and CANADA caused great economic losses and inconvenience to New York City and other affected areas. The blackout was a warning to the rest of the world that the ability of conventional power systems to meet growing electricity demand is questionable. Failure of large power systems can lead to serious emergencies. Introduction of on-site generation, renewable energy such as solar and wind power and the effective utilization of exhaust heat is needed, to meet the growing energy demands of the residential and commercial sectors. Additional benefit can be achieved by integrating these distributed technologies into distributed energy resource (DER) systems. This work demonstrates a method for choosing and designing economically optimal DER systems. An additional purpose of this research is to establish a database of energy tariffs, DER technology cost and performance characteristics, and building energy consumption for Japan. This research builds on prior DER studies at the Ernest Orlando Lawrence Berkeley National Laboratory (LBNL) and with their associates in the Consortium for Electric Reliability Technology Solutions (CERTS) and operation, including the development of the microgrid concept, and the DER selection optimization program, the Distributed Energy Resources Customer Adoption Model (DER-CAM). DER-CAM is a tool designed to find the optimal combination of installed equipment and an idealized operating schedule to minimize a site's energy bills, given performance and cost data on available DER technologies, utility tariffs, and site electrical and thermal loads over a test period, usually an historic year. Since hourly electric and thermal energy data are rarely available, they are typically developed by building simulation for each of six end use loads used to model the building: electric-only loads, space heating, space cooling, refrigeration, water heating, and natural-gas-only loads. DER-CAM provides a

    Technology innovation is becoming the fundamental momentum of China′s economic development. Potential insurance demand comes from the fact that technology innovation is always followed by high risks. However, the development of technology inno⁃vation insurance market is hindered by imperfect information and externality. And the pilot of technology insurance in some cities and new and high-tech zones is proved futile by an econometric analysis. Insurance companies, technology innovation companies, and gov⁃ernment are advised to take responsibilities to make full use of insurance to promote technology innovation. Diversified insurance pat⁃terns, higher information transparency, and improved surveillance are believed to be the most important factors for a bigger role played by insurance in technology innovation.%科技创新是未来中国发展的根本动力所在。科技创新总是伴随着较高的风险,保险潜在需求较大,但信息不完全、不对称、外部性等因素制约了科技创新保险市场的发展。对前两批科技保险试点城市和高新区的计量分析也表明,科技保险试点效果不佳。要从保险公司、科技创新企业、政府三方面着手,完善保险模式,提升信息透明度,调整监管规定,充分发挥保险促进科技创新的功能。

    Full Text Available This research study investigated relationships between an information technology (IT professional's self-assigned understanding of big data and their assessment of the maturity, value, hype, and future trends of big data. The study also examined if there was any relationship between an IT professional's understanding of big data and the position they occupy professionally. The study consisted of a twenty question survey. Research findings indicate that IT professionals are still becoming familiar with big data and related technologies. The results supported rejecting two of the five hypotheses. The study produced evidence that there is a relationship between an IT professional's level of big data understanding and their expectation that there will be an increase in technological developments related to big data in the near future.

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

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

    Liu, Jing; He, Lile; Dong, Faqin; Hudson-Edwards, Karen A

    2016-06-01

    Although the removal of arsenic(V) (As(V)) from solution can be improved by forming metal-bearing coatings on solid media, there has been no research to date examining the relationship between the coating and As(V) sorption performance. Manganese-coated bone char samples with varying concentrations of Mn were created to investigate the adsorption and desorption of As(V) using batch and column experiments. Breakthrough curves were obtained by fitting the Convection-Diffusion Equation (CDE), and retardation factors were used to quantify the effects of the Mn coatings on the retention of As(V). Uncoated bone char has a higher retention factor (44.7) than bone char with 0.465 mg/g of Mn (22.0), but bone char samples with between 5.02 mg/g and 14.5 mg/g Mn have significantly higher retention factors (56.8-246). The relationship between retardation factor (Y) and Mn concentration (X) is Y = 15.1 X + 19.8. Between 0.2% and 0.6% of the sorbed As is desorbed from the Mn-coated bone char at an initial pH value of 4, compared to 30% from the uncoated bone char. The ability of the Mn-coated bone char to neutralize solutions increases with increased amounts of Mn on the char. The results suggest that using Mn-coated bone char in Permeable Reactive Barriers would be an effective method for remediating As(V)-bearing solutions such as acid mine drainage.

    2012-01-01

    Progress toward a more sustainable society is usually described in a "knowledge-first" framework, where science characterizes a problem in terms of its causes and mechanisms as a basis for subsequent action. Here we present a different approach-A Sustainability Solutions Agenda (SSA)-which seeks from the outset to identify the possible pathways to solutions. SSA focuses on uncovering paths to sustainability by improving current technological practice, and applying existing knowledge to identify and evaluate technological alternatives. SSA allows people and organizations to transition toward greater sustainability without sacrificing essential technological functions, and therefore does not threaten the interests that depend on those functions. Whereas knowledge-first approaches view scientific information as sufficient to convince people to take the right actions, even if those actions are perceived as against their immediate interests, SSA allows values to evolve toward greater attention to sustainability as a result of the positive experience of solving a problem.

    2012-01-01

    A class of exact solutions of the Einstein-Maxwell equations is presented which contains infinite sets of gravitoelectric, gravitomagnetic and electromagnetic multipole moments. The multipolar structure of the solutions indicates that they can be used to describe the exterior gravitational field of an arbitrarily rotating mass distribution endowed with an electromagnetic field. The presence of gravitational multipoles completely changes the structure of the spacetime because of the appearance of naked singularities in a confined spatial region. The possibility of covering this region with interior solutions is analyzed in the case of a particular solution with quadrupole moment.

    Space conditioning represents nearly 50% of average residential household energy consumption, highlighting the need to identify alternative cost-effective, energy-efficient cooling and heating strategies. As homes are better built, there is an increasing need for strategies that are particularly well suited for high performance, low load homes. ARBI researchers worked with two test homes in hot-dry climates to evaluate the in-situ performance of air-to-water heat pump (AWHP) systems, an energy efficient space conditioning solution designed to cost-effectively provide comfort in homes with efficient, safe, and durable operation. Both systems were fully instrumented and have been monitored over one year to capture complete performance data over the cooling and heating seasons. Results are used to quantify energy savings, cost-effectiveness, and system performance using different operating modes and strategies. This strategy is most effective in tight, insulated homes with high levels of thermal mass (i.e. exposed slab floors).

    Numerical study results for nonlinear decay of perturbed static spherically symmetric regular solutions in the coupled system of Yang-Mills-dilaton equations are presented. The system under consideration is a coupled system of nonlinear evolution equations of a hyperbolic type. The parallel computing technique with use of multiprocessor computing system was applied in order to reduce sufficiently a total simulation time. We used parallelization of counter Thomas algorithm, which is effective for solving on two processors, as well as the partition method that allows one to solve the problem in parallel on $p$ processors with the scope to solve tridiagonal systems of linear equations that arise from finite difference approximations to the original problem. Parallel computing with use of the message passing interface (MPI) was done on cluster with $p=1,2,3,\\dots,7$ processors.

    The solutions that have been available on the market so far are basically a combination of individual components, which are combined to functioning units on the individual construction sites according to methods usually applied by the installation craftsmanship. There are different constructional units within the same craftsman business. The following distinctions are made: ventilation devices, which provide the essential functions for inlet and outlet ventilation with heat recovery in a single apparatus, gas wall heating boilers, which combine the functions of a complete heating control centre in the smallest space, and e.g. solar pumps and control groups, which combine the necessary accessories for collectors and solar storage in one constructional unit. However these individual constructional units have several disadvantages. Individual manufacturers have noticed this potential and offer a compact solution for the passive house-one-family house that combines all heating, ventilation and warm water provision functions.

    2007-01-01

    Medical errors are common, especially within the acute healthcare delivery. The identification of systemic factors associated with adverse events and the construction of models to improve the safety of the healthcare system seems straightforward, this process has been proven to be much more difficult in the realism of medical practice due to the failure of the incident reporting system to capture the essential information, especially from the perspective of junior doctors. The failure of incidence reporting system has been related to the lack of socio-technical consideration for both system designs and system implementations. The main reason of non-reporting can be conceptualised through the motivation psychology model: Maslow's hierarchy of needs; in order to achieve a change in the socio-cultural domain for incident reporting. This paper presents a qualitative research methodology approach to generate contextual-rich insights into the socio-cultural and technological factors of incident reporting among junior doctors. The research illuminates the guiding principles for future socio-technical integrated information communication technology designs and implementations. Using Maslow's hierarchy of needs as the conceptual framework, the guiding principles aim to design electronic incident reporting systems which will motivate junior doctors to participate in the process. This research paper aims to make a significant contribution to the fields of socio-technical systems and medical errors management. The design and implementation of the new incident reporting system has great potential to motivate junior doctors to change the culture of incident reporting and to work towards a safer future healthcare system.

  11. Consortium for Electric Reliability Technology Solutions Grid of the Future White Paper on Review of Recent Reliability Issues and Systems Events

    Energy Technology Data Exchange (ETDEWEB)

    Hauer, John F.; Dagle, Jeffery E.

    1999-12-01

    This report is one of six reports developed under the U.S. Department of Energy (DOE) program in Power System Integration and Reliability (PSIR). The objective of this report is to review, analyze, and evaluate critical reliability issues demonstrated by recent disturbance events in the North America power system. Eleven major disturbances are examined, most occurring in this decade. The strategic challenge is that the pattern of technical need has persisted for a long period of time. For more than a decade, anticipation of market deregulation has been a major disincentive to new investments in system capacity. It has also inspired reduced maintenance of existing assets. A massive infusion of better technology is emerging as the final option to continue reliable electrical services. If an investment in better technology will not be made in a timely manner, then North America should plan its adjustments to a very different level of electrical service. It is apparent that technical operations staff among the utilities can be very effective at marshaling their forces in the immediate aftermath of a system emergency, and that serious disturbances often lead to improved mechanisms for coordinated operation. It is not at all apparent that such efforts can be sustained through voluntary reliability organizations in which utility personnel external to those organizations do most of the technical work. The eastern interconnection shows several situations in which much of the technical support has migrated from the utilities to the Independent System Operator (ISO), and the ISO staffs or shares staff with the regional reliability council. This process may be a natural and very positive consequence of utility restructuring. If so, the process should be expedited in regions where it is less advanced.

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

  6. A hybrid geothermal energy conversion technology: Auxiliary heating of geothermally preheated water or CO2 - a potential solution for low-temperature resources

    2016-04-01

    Safe, sustainable, and economic development of deep geothermal resources, particularly in less favourable regions, often requires employment of unconventional geothermal energy extraction and utilization methods. Often "unconventional geothermal methods" is synonymously and solely used as meaning enhanced geothermal systems, where the permeability of hot, dry rock with naturally low permeability at greater depths (4-6 km), is enhanced. Here we present an alternative unconventional geothermal energy utilization approach that uses low-temperature regions that are shallower, thereby drastically reducing drilling costs. While not a pure geothermal energy system, this hybrid approach may enable utilization of geothermal energy in many regions worldwide that can otherwise not be used for geothermal electricity generation, thereby increasing the global geothermal resource base. Moreover, in some realizations of this hybrid approach that generate carbon dioxide (CO2), the technology may be combined with carbon dioxide capture and storage (CCS) and CO2-based geothermal energy utilization, resulting in a high-efficiency (hybrid) geothermal power plant with a negative carbon footprint. Typically, low- to moderate-temperature geothermal resources are more effectively used for direct heat energy applications. However, due to high thermal losses during transport, direct use requires that the heat resource is located near the user. Alternatively, we show here that if such a low-temperature geothermal resource is combined with an additional or secondary energy resource, the power production is increased compared to the sum from two separate (geothermal and secondary fuel) power plants (DiPippo et al. 1978) and the thermal losses are minimized because the thermal energy is utilized where it is produced. Since Adams et al. (2015) found that using CO2 as a subsurface working fluid produces more net power than brine at low- to moderate-temperature geothermal resource conditions, we

    A lot of experiments about the anodization of A0 pure aluminum in oxalic acid solution were carried out. The technology parameters were decided, including the anode current density, the oxidization time and the temperature of the electrolyte solution. During the anode oxidization of the pool shell, some special key technologies were solved, including the oxidization technology of large equipment, the technology of the treatment with layer by layer and sealing with thin plastic films, the selection of the power, the circular cooling of the electrolyte solution, etc. Treating the whole pool shell with such measures, the abilities of the corrosion-proof and protection were greatly improved. The nuclear reactor has run for 37 years (from 1964 to 2001), by now the oxidization film on the surface of the pool shell is still bright. It can confirm that treating of the whole pool shell is successful and necessary, which can provide the help and reference for building the same model nuclear reactors.%清华大学核能研究院屏蔽实验反应堆池壳用A0纯铝制成,并于1964年对池壳进行了全部阳极氧化处理.至2001年,反应堆运行了37年,池壳表面仍然有一层发亮的氧化膜,与国内外同类型的未经阳极氧化处理的反应堆相比较,说明氧化膜极好地保护了池壳.该反应堆池壳容积大于50 m3.表面积达100 m2,把这样大的铝制设备在完全安装完毕后进行全部表面阳极氧化处理,在处理工艺上是很困难的.本文阐明了解决这些问题的方法.对A0纯铝在草酸中的阳极氧化做了许多实验,获得了A0纯铝在3%(w/%)草酸中的阳极氧化的基本规律,并确定了最终的工艺参数.包括氧化电流密度,氧化时间和电解液的温度.在铝池壳的阳极氧化过程中解决了许多关键的工艺:如大型工件阳极氧化工艺、氧化机制、性能;分层处理与薄膜密封技术;电源的选择;电解液的循环冷却;氧化膜的质量检测等.

    In classical continuum physics, a wave is a mechanical disturbance. Whether the disturbance is stationary or traveling and whether it is caused by the motion of atoms and molecules or the vibration of a lattice structure, a wave can be understood as a specific type of solution of an appropriate mathematical equation modeling the underlying physics. Typical models consist of partial differential equations that exhibit certain general properties, e.g., hyperbolicity. This, in turn, leads to the possibility of wave solutions. Various analytical techniques (integral transforms, complex variables, reduction to ordinary differential equations, etc.) are available to find wave solutions of linear partial differential equations. Furthermore, linear hyperbolic equations with higher-order derivatives provide the mathematical underpinning of the phenomenon of dispersion, i.e., the dependence of a wave's phase speed on its wavenumber. For systems of nonlinear first-order hyperbolic equations, there also exists a general ...

    This dissertation investigates the atomic power solution in Finland between 1955 - 1970. During these years a national arrangement for atomic energy technology evolved. The foundations of the Finnish atomic energy policy; the creation of basic legislation and the first governmental bodies, were laid between 1955 - 1965. In the late 1960's, the necessary technological and political decisions were made in order to purchase the first commercial nuclear reactor. A historical narration of this process is seen in the international context of 'atoms for peace' policies and Cold War history in general. The geopolitical position of Finland made it necessary to become involved in the balanced participation in international scientific-technical exchange and assistive nuclear programs. The Paris Peace Treaty of 1947 categorically denied Finland acquisition of nuclear weapons. Accordingly, from the 'Geneva year' of 1955, the emphasis was placed on peaceful purposes for atomic energy as well as on the education of national professionals in Finland. An initiative for the governmental atomic energy commission came from academia but the ultimate motive behind it was an anticipated structural change in the supply of national energy. Economically exploitable hydro power resources were expected to be built within ten years and atomic power was seen as a promising and complementing new energy technology. While importing fuels like coal was out of the question, because of scarce foreign currency, domestic uranium mineral deposits were considered as a potential source of nuclear fuel. Nevertheless, even then nuclear energy was regarded as just one of the possible future energy options. In the mid-1960 s a bandwagon effect of light water reactor orders was witnessed in the United States and soon elsewhere in the world. In Finland, two separate invitations for bids for nuclear reactors were initiated. This study explores at length both their preceding grounds and

    This paper studied limiting factor (high temperature stress occurred during grain filling period) for high yield production of spring maize in North China Plain (NCP).By analyzing the available high yield technologic solutions for spring maize under high temperature stress (HTS),we expected that spring maize might break the barriers from HTS during grain filling period in NCP.The results showed that the main clinical manifestations of spring maize under HTS at filling stage included,shortened the linear growth stage of maize grain; reduced the grain size and the amount of assimilate transfer to grain,leading to a reduced grain filling rate; pollen abortion and mismatched pollination period which reduced seed setting rate; the temperature over 35 ℃ would reduce root growth rate and hindered the lateral root growth;reduced photosynthetic enzyme activity,chlorophyll content and PSI I function,which resulting in photosynthesis reduction;lowered leaf water status and plant nitrogen accumulation;induced sheath blight and bacterial wilt.To break the barrier exerted by HTS on spring maize during grain filling stage,the following practices could be used:advancing or delaying sowing date to avoid high temperature,breeding high temperature tolerant maize varieties; applying chemicals such as exogenous salicylic acid (SA),kinetin (BA) and abscisic acid (ABA) to improve the tolerance; pre-exercising with high temperature well before the grain filling stage; practicing agronomic and farming approaches to regulate the nutrition levels and soil and water and light properties.Based on this study,a design integrated technology of the individual techniques could be used to form an integrated technology system,thus to improve heat tolerance and increase spring maize yield under HTS in NCP.%本研究针对华北平原春玉米一熟制高产的限制因子(灌浆期高温胁迫)问题,在分析了国内外高温对玉米胁迫影响机理的相关研究基础上,

    Future Climate Engineering Solutions - Joint Report is the common output and a documentation of more than 1 year's effort by 13 engineering associations - in 12 countries - to demonstrate how technologies can combat climate change. The report consists of three parts: Summaries of 10 national climate plans and technology prospects, 5 Key Common Findings, and a Climate Call from Engineers to create a new global climate treaty. The basic assumption of the project is recognition that GHG emissions, and their concentration in the atmosphere, must be reduced to a sustainable level. The project definition of a sustainable level is equivalent to the best-case stabilisation scenario which was presented in the 4th Assessment Report (AR4) by the UN Intergovernmental Panel on Climate Change (IPCC), whereby the global mean temperature is most likely to stabilise at 2.0-2.4 deg.

    2014-01-01

    Attaining sustainable agriculture is a key goal in many parts of the world. The increased environmental awareness and the ongoing attempts to execute agricultural practices that are economically feasible and environmentally safe promote the use of hydroponic cultivation. Hydroponics is a technology for growing plants in nutrient solutions with or without the use of artificial medium to provide mechanical support. Major problems for hydroponic cultivation are higher operational cost and the causing of pollution due to discharge of waste nutrient solution. The nutrient effluent released into the environment can have negative impacts on the surrounding ecosystems as well as the potential to contaminate the groundwater utilized by humans for drinking purposes. The reuse of non-recycled, nutrient-rich hydroponic waste solution for growing plants in greenhouses is the possible way to control environmental pollution. Many researchers have successfully grown several plant species in hydroponic waste solution with high yield. Hence, this review addresses the problems associated with the release of hydroponic waste solution into the environment and possible reuse of hydroponic waste solution as an alternative resource for agriculture development and to control environmental pollution.

    1997-05-01

    While they are many, one of the inhibitors to the wide spread diffusion of PACS systems has been robust, cost effective digital archive storage solutions. Moreover, an automated Nearline solution is key to a central, sharable data repository, enabling many applications such as PACS, telemedicine and teleradiology, and information warehousing and data mining for research such as patient outcome analysis. Selecting the right solution depends on a number of factors: capacity requirements, write and retrieval performance requirements, scaleability in capacity and performance, configuration architecture and flexibility, subsystem availability and reliability, security requirements, system cost, achievable benefits and cost savings, investment protection, strategic fit and more.This paper addresses many of these issues. It compares and positions optical disk and magnetic tape technologies, which are the predominant archive mediums today. Price and performance comparisons will be made at different archive capacities, plus the effect of file size on storage system throughput will be analyzed. The concept of automated migration of images from high performance, high cost storage devices to high capacity, low cost storage devices will be introduced as a viable way to minimize overall storage costs for an archive. The concept of access density will also be introduced and applied to the selection of the most cost effective archive solution.

Ces progrès interpellent quotidiennement médecins et personnel infirmier, posant des défis pour lesquels peu de réponses existent. Normes et valeurs s’actualisent en ces lieux où des enjeux entourant la vie, la “qualité” de vie, et la mort sont quotidiens. L’hôpital pédiatrique est certes un endroit où tous les espoirs sont permis. C’est aussi un lieu où la mort est à apprivoiser ; elle devient un choix, s’imposant rarement d’elle-même. Sur la base des témoignages des soignants et de nos propres observations, nous proposons une réflexion sur la ‘fin de vie’, objet d’un choix difficile, en dialogue avec la technologie qui la rend possible. Ces différentes voix témoigneront de rationalités parfois parallèles, convergentes ou divergentes, et des normes et valeurs qui s’affrontent, se rencontrent et se négocient dans l’espace social de la clinique.Stemming from an anthropological study of clinical practices in tertiary health care institutions, our paper focuses on challenges brought by medical and technological progress in paediatric intensive care units (acute and oncology units (chronic.

    Hancock, Nathan T; Cath, Tzahi Y

    2009-09-01

    Forward osmosis (FO) is an emerging water treatment technology with potential applications in desalination and wastewater reclamation. In FO, water is extracted from a feed solution using the high osmotic pressure of a hypertonic solution that flows on the opposite side of a semipermeable membrane; however, solutes diffuse simultaneously through the membrane in both directions and may jeopardize the process. In this study, we have comprehensively explored the effects of different operating conditions on the forward diffusion of solutes commonly found in brackish water and seawater, and reverse diffusion of common draw solution solutes. Results show that reverse transport of solutes through commercially available FO membranes range between 80 mg to nearly 3,000 mg per liter of water produced. Divalent feed solutes have low permeation rates (less than 1 mmol/m2-hr) while monovalent ions and uncharged solutes exhibit higher permeation. Findings have significant implications on the performance and sustainability of the FO process.

    1980-09-01

    The steel industry is faced with serious problems caused by the increasing cost of energy, labor and capital and by tough overseas competition, employing new highly efficient process plants. The very high cost of capital and of capital equipment renders the construction of new green field site plants, exemplifying the best available technology economically unattractive. For this reason, over the long term the development radically innovative steelmaking technologies appears to be the only satisfactory resolution of this dilemma. The purpose of this article is to present a critical review of some of the radically innovative steelmaking technologies that have been proposed during the past few years and to develop the argument that these indeed do deserve serious consideration at the present time. It should be stressed, however, that these innovative technologies can be implemented only as part of a carefully conceived long range plan, which contains as a subset short term solutions, such as trigger prices improved investment credits, and so forth and intermediate term solutions, such as more extensive use of continuous casting, external desulfurization and selective modernization in general.

    Experiments were carried out on highly ordered GdAl{sub 2} samples containing extremely dilute mole fractions of{sup 111}In/Cd probe-atom solutes (about 10{sup −11}), intrinsic antisite atoms Al{sub Gd} having mole fractions of order 0-10{sup −2}, and doped with Ag solutes at mole fractions of order 10{sup −2}. Three types of defect interactions were investigated. (1) Quadrupole interactions caused by Ag-solute atoms neighboring{sup 111}In/Cd solute probe atoms were detected using the method of perturbed angular correlation of gamma rays (PAC). Three complexes of pairs of In-probes and Ag-solutes occupying neighboring positions on Gd- and Al-sublattices were identified by comparing site fractions in Gd-poor and Gd-rich GdAl{sub 2}(Ag) samples and from the symmetry of the quadrupole interactions. Interaction enthalpies between solute-atom pairs were determined from temperature dependences of observed site fractions. Repulsive interactions were observed for close-neighbor complexes In{sub Gd}+Ag{sub Gd} and In{sub Gd}+Ag{sub Al} pairs, whereas a slightly attractive interaction was observed for In{sub Al}+Ag{sub Al}. Interaction enthalpies were all small, in the range ±0.15 eV. (2) Quadrupole interactions caused by intrinsic antisite atoms Al{sub Gd} neighboring In{sub Gd} probes were also detected and site fractions measured as a function of temperature, as in previous work on samples not doped with Ag-solutes [Temperature- and composition-driven changes in site occupation of solutes in Gd{sub 1+3x}Al{sub 2−3x}, Zacate and Collins (Phys. Rev. B69, 174202 (1))]. However, the effective binding enthalpy between In{sub Gd} probe and Al{sub Gd} antisite was found to change sign from -0.12 eV (attractive interaction) in undoped samples to + 0.24 eV (repulsive) in Ag-doped samples. This may be attributed to an attractive interaction between Al{sub Gd} antisite atoms and Ag-dopants that competes with the attractive interaction between In{sub Gd} and Al{sub Gd

The system involves a set of functions on a three-dimensional base metric. We obtain a family of non-extremal axisymmetric solutions that generalize the known multicenter extremal solutions, using a particular base metric that introduces a bolt. We analyze the conditions for regularity, and in doing so we show that this family does not include solutions that contain an extremal black hole and a smooth bolt. We determine the constraints that are necessary to obtain smooth horizonless solutions involving a bolt and an arbitrary number of Gibbons-Hawking centers.

    2014-05-01

    The threat of nuclear terrorism is real and poses a significant challenge to both U.S. and global security. For terrorists, the challenge is not so much the actual design of an improvised nuclear device (IND) but more the acquisition of the special nuclear material (SNM), either highly enriched uranium (HEU) or plutonium, to make the fission weapon. This paper provides two examples of technical solutions that were developed in support of the nonproliferation objective of reducing the opportunity for acquisition of HEU. The first example reviews technologies used to monitor centrifuge enrichment plants to determine if there is any diversion of uranium materials or misuse of facilities to produce undeclared product. The discussion begins with a brief overview of the basics of uranium processing and enrichment. The role of the International Atomic Energy Agency (IAEA), its safeguard objectives and how the technology evolved to meet those objectives will be described. The second example focuses on technologies developed and deployed to monitor the blend down of 500 metric tons of HEU from Russia's dismantled nuclear weapons to reactor fuel or low enriched uranium (LEU) under the U.S.-Russia HEU Purchase Agreement. This reactor fuel was then purchased by U.S. fuel fabricators and provided about half the fuel for the domestic power reactors. The Department of Energy established the HEU Transparency Program to provide confidence that weapons usable HEU was being blended down and thus removed from any potential theft scenario. Two measurement technologies, an enrichment meter and a flow monitor, were combined into an automated blend down monitoring system (BDMS) and were deployed to four sites in Russia to provide 24/7 monitoring of the blend down. Data was downloaded and analyzed periodically by inspectors to provide the assurances required.

    Greywater recycling is now accepted as a sustainable solution to the general increase of the fresh water demand, water shortages and for environment protection. However, the majority of the suggested treatments are biological and such technologies can be affected, especially at small scale, by the variability in strength and flow of the greywater and potential shock loading. This investigation presents the study of alternative processes, coagulation and magnetic ion exchange resin, for the treatment of greywater for reuse. The potential of these processes as well as the influence of parameters such as coagulant or resin dose, pH or contact time were investigated for the treatment of two greywaters of low and high organic strengths. The results obtained revealed that magnetic ion exchange resin and coagulation were suitable treatment solutions for low strength greywater sources. However, they were unable to achieve the required level of treatment for the reuse of medium to high strength greywaters. Consequently, these processes could only be considered as an option for greywater recycling in specific conditions that is to say in case of low organic strength greywater or less stringent standards for reuse.

    Full Text Available Cloud computing can be defined as a new style of computing in which dynamically scala-ble and often virtualized resources are provided as a services over the Internet. Advantages of the cloud computing technology include cost savings, high availability, and easy scalability. Voas and Zhang adapted six phases of computing paradigms, from dummy termi-nals/mainframes, to PCs, networking computing, to grid and cloud computing. There are four types of cloud computing: public cloud, private cloud, hybrid cloud and community. The most common and well-known deployment model is Public Cloud. A Private Cloud is suited for sensitive data, where the customer is dependent on a certain degree of security.According to the different types of services offered, cloud computing can be considered to consist of three layers (services models: IaaS (infrastructure as a service, PaaS (platform as a service, SaaS (software as a service. Main cloud computing solutions: web applications, data hosting, virtualization, database clusters and terminal services. The advantage of cloud com-puting is the ability to virtualize and share resources among different applications with the objective for better server utilization and without a clustering solution, a service may fail at the moment the server crashes.DOI: 10.15181/csat.v2i2.914

  3. Brainmining emotive lateral solutions

    Directory of Open Access Journals (Sweden)

    Theodore Scaltsas

    2016-07-01

    Full Text Available BrainMining is a theory of creative thinking that shows how we should exploit the mind’s spontaneous natural disposition to use old solutions to address new problems – our Anchoring Cognitive Bias. BrainMining develops a simple and straightforward method to transform recalcitrant problems into types of problems which we have solved before, and then apply an old type of solution to them. The transformation makes the thinking lateral by matching up disparate types of problem and solution. It emphasises the role of emotive judgements that the agent makes, when she discerns whether a change of the values or the emotions and feelings in a situation, which would expand the space of solutions available for the problem at hand, would be acceptable or appropriate in the situation. A lateral solution for an intractable problem is thus spontaneously brainmined from the agent’s old solutions, to solve a transformed version of the intractable problem, possibly involving changes in the value system or the emotional profile of the situation, which the agent judges, emotively, will be acceptable, and even appropriate in the circumstances.

    The sports facilities are characterized by special energy needs different from any other user and they are characterized by high heat and electricity loads. For this reason, the aim of this work has been to propose a tool to provide a preliminary estimation of the power and energy required by the sports centres. In addition, the possibility to make the building self-energy sufficient has been considered, thanks to the exploitation of renewable energy sources (RES). The overall work has been performed following three steps: energy needs analysis; local RES availability analysis; energy balance of Sport Centres. Considering that each sport facility is characterized by different energy needs depending on the sport typology itself, the analysis started from the features established by the CONI (National Italian Olympic Committee) standardization. For calculations a program in LabVIEW has been developed to evaluate the energy requirements of the sports centre considering as inputs the sport halls, the playgrounds and the supporting rooms, the level of the sport activity (e.g. agonistic) and the climatic conditions of the area where the facilities are located. The locally available RES are evaluated in order to decide which one can be exploited to feed the Sport Centre. The proposed solution for the energy production refers to a combination of different and innovative technologies which involve, in particular, hydrogen technologies. The energy and costs analysis has been finally carried out for an application case in Dubai. (author)

    The technology performance level (TPL) assessments can be applied at all technology development stages and associated technology readiness levels (TRLs). Even, and particularly, at low TRLs the TPL assessment is very effective as it, holistically, considers a wide range of WEC attributes that determine the techno-economic performance potential of the WEC farm when fully developed for commercial operation. The TPL assessment also highlights potential showstoppers at the earliest possible stage of the WEC technology development. Hence, the TPL assessment identifies the technology independent “performance requirements.” In order to achieve a successful solution, the entirety of the performance requirements within the TPL must be considered because, in the end, all the stakeholder needs must be achieved. The basis for performing a TPL assessment comes from the information provided in a dedicated format, the Technical Submission Form (TSF). The TSF requests information from the WEC developer that is required to answer the questions posed in the TPL assessment document.

    2006-05-15

    PEP stands for 'Promotion of European Passive Houses' and is a consortium of European partners, supported by the European Commission, Directorate General for Energy and Transport. In this working paper an overview is given of Passive House solutions. An inventory has been made of Passive House solutions for new build residences applied in each country. Based on this, the most common basic solutions have been identified and described in further detail, including the extent to which solutions are applied in common and best practice and expected barriers for the implementation in each country. An inventory per country is included in the appendix. The analysis of Passive House solutions in partner countries shows high priority with regard to the performance of the thermal envelope, such as high insulation of walls, roofs, floors and windows/ doors, thermal bridge-free construction and air tightness. Due to the required air tightness, special attention must be paid to indoor air quality through proper ventilation. Finally, efficient ((semi-)solar) heating systems for combined space and DHW heating still require a significant amount of attention in most partner countries. Other basic Passive House solutions show a smaller discrepancy with common practice and fewer barriers have been encountered in partner countries. In the next section, the general barriers in partner countries have been inventoried. For each type of barrier a suggested approach has been given. Most frequently encountered barriers in partner countries are: limited know-how; limited contractor skills; and acceptation of Passive Houses in the market. Based on the suggested approaches to overcoming barriers, this means that a great deal of attention must be paid to providing practical information and solutions to building professionals, providing practical training to installers and contractors and communication about the Passive House concept to the market.
