    This study was undertaken to determine the technical feasibility of upgrading the Waste Experimental Reduction Facility (WERF) at the Idaho National Engineering and Environmental Laboratory to meet the offgas emission limits proposed in the Maximum Achievable Control Technologies (MACT)rule. Four practicable offgas treatment processes were identified, which, if installed, would enable the WERF to meet the anticipated MACT emission limits for dioxins and furans (D/F), hydrochloric acid (HCI), and mercury (Hg). Due to the three-year time restraint for MACT compliance, any technology chosen for the upgrade must be performed within the general plant project funding limit of $5 M. The option selected consists of a partial-quench evaporative cooler with dry sorbent injection for HCI removal followed by a sulfur-impregnated activated carbon bed for Hg control. The planning cost estimate for implementing the option is $4.17 M (with 24% contingency). The total estimated cost includes capital costs, design and construction costs, and project management costs. Capital costs include the purchase of a new offgas evaporative cooler, a dry sorbent injection system with reagent storage, a new fabric filter baghouse, a fixed carbon bed absorber, and two offgas induced draft exhaust fans. It is estimated that 21 months will be required to complete the recommended modification to the WERF. The partial-quench cooler is designed to rapidly cool the offgas exiting the secondary combustion chamber to minimize D/F formation. Dry sorbent injection of an alkali reagent into the offgas is recommended. The alkali reacts with the HCI to form a salt, which is captured with the fly ash in the baghouse. A design HCI removal efficiency of 97.2% allows for the feeding 20 lbs/hr of chlorine to the WERF incinerator. The sorbent feed rate can be adjusted to achieve the desired HCI removal efficiency. A fixed bed of sulfur-impregnated carbon was conservatively sized for a total Hg removal capacity when

    About one million gallons of acidic, hazardous, and radioactive sodium-bearing waste are stored in stainless steel tanks at the Idaho Nuclear Technology and Engineering Center (INTEC), which is a major operating facility of the Idaho National Engineering and Environmental Laboratory. Calcination at high-temperature conditions (600 C, with alumina nitrate and calcium nitrate chemical addition to the feed) is one of four options currently being considered by the Department of Energy for treatment of the remaining tank wastes. If calcination is selected for future processing of the sodium-bearing waste, it will be necessary to install new off-gas control equipment in the New Waste Calcining Facility (NWCF) to comply with the Maximum Achievable Control Technology (MACT) standards for hazardous waste combustors and incinerators. This will require, as a minimum, installing a carbon bed to reduce mercury emissions from their current level of up to 7,500 to <45 {micro}g/dscm, and a staged combustor to reduce unburned kerosene fuel in the off-gas discharge to <100 ppm CO and <10 ppm hydrocarbons. The staged combustor will also reduce NOx concentrations of about 35,000 ppm by 90-95%. A pilot-plant calcination test was completed in a newly constructed 15-cm diameter calciner vessel. The pilot-plant facility was equipped with a prototype MACT off-gas control system, including a highly efficient cyclone separator and off-gas quench/venturi scrubber for particulate removal, a staged combustor for unburned hydrocarbon and NOx destruction, and a packed activated carbon bed for mercury removal and residual chloride capture. Pilot-plant testing was performed during a 50-hour system operability test January 14-16, followed by a 100-hour high-temperature calcination pilot-plant calcination run January 19-23. Two flowsheet blends were tested: a 50-hour test with an aluminum-to-alkali metal molar ratio (AAR) of 2.25, and a 50-hour test with an AAR of 1.75. Results of the testing

    The objectives of the present study were 1) to determine the heterogeneity of the MAC-T cell line; 2) to examine whether homogeneous clones could be derived from MAC-T cells; and 3) to examine cell morphology, cytoskeletal characteristics, size, colony-forming ability, growth characteristics, beta-casein production, response to oxytocin, and cytogenetic properties of the clones. Three clonal cells, designated CU-1, CU-2, and CU-3, were derived from MAC-T cells. CU-1 and CU-2 cells were morphologically homogeneous. CU-3 cells were heterogeneous and contained two distinct subtypes. All clones contained cytokeratin 14 and 18. CU-2 and CU-3 cells were 30 and 18% larger, respectively, than CU-1 cells. CU-1 cells did not grow in serum-free medium. Doubling times for MAC-T, CU-2, and CU-3 were 46, 48, and 78 h, respectively, in serum-free medium. MAC-T cells and clones constitutively expressed beta-casein in culture ranging from .1 to .3 micrograms/ml per 24 h. Cytogenetic analyses revealed Robertsonian translocations and isochromosomes in the clonal lines. We conclude that parental MAC-T cells are heterogeneous in morphology, growth, and cytogenetic characteristics.

    2014-01-01

    Given the effect of musical training on the rate and accuracy of processing auditory information, therapeutic uses of music may potentially have remedial benefits for individuals with neurodevelopmental deficits. However, additional studies are needed to establish efficacy of music therapy interventions for attention skills in children/adolescents with neurodevelopmental disabilities including those with Autism Spectrum Disorders (ASD). To establish feasibility and preliminary efficacy of a group music therapy protocol to improve attention skills (sustained, selective, attentional control/switching) in adolescents diagnosed with autism and/or developmental delays. This single group pretest/posttest study took place in a private school for high functioning adolescents with neurodevelopmental delays. Nine students (4 males, 5 females), ages 13 to 20, participated in the study. Autism severity was assessed using the CARS2-HF and indicated the following distribution for study participants: severe (n = 3), mild (n = 4), or minimal/no (n = 2) symptoms. We assessed feasibility of implementing a 45-min Musical Attention Control Training (MACT) intervention delivered by a board-certified music therapist eight times over 6 weeks in a school setting. We also examined preliminary efficacy of the MACT to improve attention skills using the Test of Everyday Attention for Children (TEA-Ch). Parental consent rate was 100%. All nine participants successfully completed testing measures and 6 weeks of the intervention. Average participation rate was 97%. Data analysis showed positive trends and improvements on measures of attentional control/switching and selective attention. The results showed that the intervention and testing measures were feasible to implement and acceptable to the participants who all completed the protocol. Data analysis demonstrated positive trends indicating that more research on the use of music therapy attention training in high-functioning adolescents with

    Currently, centrifuge apparatus is primarily an end-point sample processing piece of equipment. The lack of real-time active control has imposed an inherent limitation such that many delicate sample processing steps requiring immediate and accurate intervention have never been possible. We report herein a motor-assisted chip-in-a-tube (MACT) platform in which a microfluidic chip placed inside a common centrifuge canister can be rotated through wireless control in order to manipulate the centrifugal force vector in a 3-dimensional (3D) manner. As a demonstration experiment, we have used our MACT prototype to perform the operation for two common biomedical procedures, namely human blood plasma separation and E. coli plasmid DNA extraction. This simple, yet highly effective and versatile approach may serve as a generic one-for-all platform for a wide range of common laboratory experiments and bioassay applications.

    The aim of this study was to use morphological as well as biochemical (T2 and T2* relaxation times and diffusion-weighted imaging (DWI)) magnetic resonance imaging (MRI) for the evaluation of healthy cartilage and cartilage repair tissue after matrix-associated autologous chondrocyte transplantation (MACT) of the ankle joint. Ten healthy volunteers (mean age, 32.4 years) and 12 patients who underwent MACT of the ankle joint (mean age, 32.8 years) were included. In order to evaluate possible maturation effects, patients were separated into short-term (6-13 months) and long-term (20-54 months) follow-up cohorts. MRI was performed on a 3.0-T magnetic resonance (MR) scanner using a new dedicated eight-channel foot-and-ankle coil. Using high-resolution morphological MRI, the magnetic resonance observation of cartilage repair tissue (MOCART) score was assessed. For biochemical MRI, T2 mapping, T2* mapping, and DWI were obtained. Region-of-interest analysis was performed within native cartilage of the volunteers and control cartilage as well as cartilage repair tissue in the patients subsequent to MACT. The overall MOCART score in patients after MACT was 73.8. T2 relaxation times ({proportional_to}50 ms), T2* relaxation times ({proportional_to}16 ms), and the diffusion constant for DWI ({proportional_to}1.3) were comparable for the healthy volunteers and the control cartilage in the patients after MACT. The cartilage repair tissue showed no significant difference in T2 and T2* relaxation times (p{>=}0.05) compared to the control cartilage; however, a significantly higher diffusivity ({proportional_to}1.5; p<0.05) was noted in the cartilage repair tissue. The obtained results suggest that besides morphological MRI and biochemical MR techniques, such as T2 and T2* mapping, DWI may also deliver additional information about the ultrastructure of cartilage and cartilage repair tissue in the ankle joint using high-field MRI, a dedicated multichannel coil, and sophisticated

The estimations are carried out with time-series data from 1970 to 2006 using the Johansen estimation techniques. The study is distinct from most of the existing literature since it made an attempt in generating a time-varying technological progress. It employs the Kalman filter technique to determine the evolution of the Solow residual estimated from a Cobb-Douglas production function. The results conform to the existing literature that macroeconomic instability, the level of financial development, and the level of human development are highly significant determinants of technological progress in Nigeria.

    The use of technology is increasingly important in nursing education and practice. For this reason, it is necessary to determine the attitudes of nursing students towards technology. This study was conducted with 508 nursing students. A personal information form that was prepared by the researchers and the Attitudes Toward Technology Scale were used as the data collection tools. The mean score that was obtained by the nursing students from the Attitudes Toward Technology Scale was 61.53 ± 1.13. The Cronbach's alpha coefficient was found to be 0.90. There was a statistically significant difference between the sexes, using a computer, tablet, or laptop, using technology to reach health-related information, and for professional development, using mobile applications related to drug information. There was also a statistical difference between using the Periscope and Scorpio accounts from social media and using Excel and PowerPoint from Microsoft programs. Nursing students are capable of technology-based teaching, which can be expanded as a result. © 2018 Japan Academy of Nursing Science.

  2. Determination and acceptance of the risks of technologies

    1982-01-01

    As a consequence of the problems posed by modern technologies (e.g. nuclear power), a new discipline 'risk assessment' has developed over the last decade. The paper describes, first, some studies on determinants of perceived risk, e.g. frequency of accidents, catastrophic potential, voluntariness, dreadfulness, and controllability. Cognitive factors which help explaining research findings include availability, overconfidence, and perceptual set. Secondly, studies on the acceptability of risk are presented in which the focus is on the relation between perceived risk and perceived benefit. Following this, a brief outline of methods is given that have been suggested for determining the acceptability of risk (revealed preferences, expressed preferences, cost-benefit analysis, and decision analysis). Finally, the impact of the development of risky technologies and of risk research is discussed as it is evidenced in the controversies that have emerged within the scientific community, between science and politics, and between science and the public.

  3. Technological Determinism and Permissionless Innovation as Technocratic Governing Mentalities: Psychocultural Barriers to the Democratization of Technology

    Directory of Open Access Journals (Sweden)

    Taylor Dotson

    2015-12-01

    Full Text Available Despite no shortage of thoughtful analysis concerning how to more democratically develop and assess new technologies, practical progress toward democratized innovation has been paltry. This state of affairs suggests that the barriers to such democratic ends merit more attention. Building upon calls to more seriously examine citizens’ understandings of technology as autonomous or deterministic, this paper characterizes the assumptions, beliefs, and patterns of thought undergirding technological determinism and permissionless innovation as technocratic governing mentalities. That is, they contribute to the biasing of political discourses, practices, and organizations toward non-decision making and adaptation with regards to technological change. Indeed, permissionless innovation is quickly becoming the motto of those aiming to legitimate a “hands-off” approach to the sociotechnical “disruptions” sought by Silicon Valley entrepreneurs. Moreover, this paper explores how STS, as both an academic and political endeavor, might better respond to the challenges these modes of thinking present. Drawing upon relevant work within social psychology and communications, several fruitful avenues for engaged research regarding undermining technocratic governing mentalities become apparent. Not only is there a pressing need for accessible and parsimonious counternarratives to technological determinism and permissionless innovation but also rhetorical strategies for making the democratization of technological appear continuous with aspects of status quo systems. Finally, given that technocratic governing mentalities are likely to have practical and material roots, inquiry should be directed toward understanding how different sociotechnical arrangements impact citizens’ perception of the desirability and feasibility of democratizing technology.

  4. Mercury emissions control technologies for mixed waste thermal treatment

    1997-01-01

    EPA has identified wet scrubbing at low mercury feedrates, as well as carbon adsorption via carbon injection into the offgas or via flow through fixed carbon beds, as control technologies that can be used to meet the proposed Maximum Achievable Control Technology (MACT) rule limit for mercury emissions from hazardous waste incinerators. DOE is currently funding demonstrations of gold amalgamation that may also control mercury to the desired levels. Performance data from a variety of sources was reviewed to determine ranges of achievable mercury control. Preliminary costs were estimated for using these technologies to control mercury emissions from mixed waste incineration. Mercury emissions control for mixed waste incineration may need to be more efficient than for incineration of other hazardous wastes because of higher mercury concentrations in some mixed waste streams. However, mercury control performance data for wet scrubbing and carbon adsorption is highly variable. More information is needed to demonstrate control efficiencies that are achievable under various design and operating conditions for wet scrubbing, carbon adsorption, and gold amalgamation technologies. Given certain assumptions made in this study, capital costs, operating costs, and lifecycle costs for carbon injection, carbon beds, and gold amalgamation generally vary for different assumed mercury feedrates and for different offgas flowrates. Assuming that these technologies can in fact provide the necessary mercury control performance, each of these technologies may be less costly than the others for certain mercury feedrates and the offgas flowrates

    Present weather sensors are becoming increasingly important as a means to augment networks of automated weather stations and extend the capability of manned observations. The classification of hydrometeors is one of the principal tasks that is addressed by present weather sensors. In this paper, we discuss a new laser-based technology for this purpose. The system improves upon current precipitation monitors by using a derivative of phase Doppler anemometry techniques to accurately determine particle speed and size. The instrument is also capable of distinguishing between liquid droplets and solid polycrystalline hydrometeors and can be used to estimate visibility. The incorporation of this technology into a meteorological station with other sensors, such as temperature and relative humidity probes, leads to the accurate classification of particle type. The example data shown are taken from tests in Leicestershire, England and Utah, USA and show the differences between solid and liquid precipitation events.

    2006-12-15

    Three new methods applicable to the determination of hazardous metal concentrations in stationary source emissions were developed and evaluated for use in U.S. Environmental Protection Agency (EPA) compliance applications. Two of the three independent methods, a continuous emissions monitor-based method (Xact) and an X-ray-based filter method (XFM), are used to measure metal emissions. The third method involves a quantitative aerosol generator (QAG), which produces a reference aerosol used to evaluate the measurement methods. A modification of EPA Method 301 was used to validate the three methods for As, Cd, Cr, Pb, and Hg, representing three hazardous waste combustor Maximum Achievable Control Technology (MACT) metal categories (low volatile, semivolatile, and volatile). The measurement methods were evaluated at a hazardous waste combustor (HWC) by comparing measured with reference aerosol concentrations. The QAG, Xact, and XFM met the modified Method 301 validation criteria. All three of the methods demonstrated precisions and accuracies on the order of 5%. The measurement methods should be applicable to emissions from a wide range of sources, and the reference aerosol generator should be applicable to additional analytes. EPA recently approved an alternative monitoring petition for an HWC at Eli Lilly's Tippecanoe site in Lafayette, IN, in which the Xact is used for demonstrating compliance with the HWC MACT metal emissions (low volatile, semivolatile, and volatile). The QAG reference aerosol generator was approved as a method for providing a quantitative reference aerosol, which is required for certification and continuing quality assurance of the Xact. 30 refs., 5 figs., 11 tabs.

  8. Cognitive Determinants of the Effectiveness of Technological Interfaces

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available Interface plays an important function in the operational process of modern interactive information technologies. Its task is to enable communication, signal exchange, and cooperation with the human mind. Technological interface is understood as the place where technology and software operating a computer must enter into interaction with the mind. The response is provided by the mind, which communicates with the machine performing the tasks imposed by the mind. The technology with its complexities can be a problem for the operator, but on the other hand, the person can also be a problem for the technology by vague and unspecified tasks transferred for execution. I would like to view various aspects of the functioning of the interface by analyzing the four modalities: perceptual modality, associated with memory and experience, with the expectations of users, and conceptual modality related to understanding of the technology by the user.

    As the National Aeronautics and Space Administration (NASA) prepares to extend human presence throughout the solar system, technical capabilities must be developed to enable long duration flights to destinations such as near Earth asteroids, Mars, and extended stays on the Moon. As part of the NASA Human Spaceflight Architecture Team, a Technology Development Assessment Team has identified a suite of critical technologies needed to support this broad range of missions. Dialog between mission planners, vehicle developers, and technologists was used to identify a minimum but sufficient set of technologies, noting that needs are created by specific mission architecture requirements, yet specific designs are enabled by technologies. Further consideration was given to the re-use of underlying technologies to cover multiple missions to effectively use scarce resources. This suite of critical technologies is expected to provide the needed base capability to enable a variety of possible destinations and missions. This paper describes the methodology used to provide an architecture-driven technology development assessment ("technology pull"), including technology advancement needs identified by trade studies encompassing a spectrum of flight elements and destination design reference missions.

    NASA is investing in new technologies that include 14 primary technology roadmap areas, and aeronautics. Understanding the cost for research and development of these technologies and the time it takes to increase the maturity of the technology is important to the support of the ongoing and future NASA missions. Overall, technology estimating may help provide guidance to technology investment strategies to help improve evaluation of technology affordability, and aid in decision support. The research provides a summary of the framework development of a Technology Estimating process where four technology roadmap areas were selected to be studied. The framework includes definition of terms, discussion for narrowing the focus from 14 NASA Technology Roadmap areas to four, and further refinement to include technologies, TRL range of 2 to 6. Included in this paper is a discussion to address the evaluation of 20 unique technology parameters that were initially identified, evaluated and then subsequently reduced for use in characterizing these technologies. A discussion of data acquisition effort and criteria established for data quality are provided. The findings obtained during the research included gaps identified, and a description of a spreadsheet-based estimating tool initiated as a part of the Technology Estimating process.

    Understanding the factors driving innovation in energy technologies is of critical importance to mitigating climate change and addressing other energy-related global challenges. Low levels of innovation, measured in terms of energy patent filings, were noted in the 1980s and 90s as an issue of concern and were attributed to limited investment in public and private research and development (R&D). Here we build a comprehensive global database of energy patents covering the period 1970–2009, which is unique in its temporal and geographical scope. Analysis of the data reveals a recent, marked departure from historical trends. A sharp increase in rates of patenting has occurred over the last decade, particularly in renewable technologies, despite continued low levels of R&D funding. To solve the puzzle of fast innovation despite modest R&D increases, we develop a model that explains the nonlinear response observed in the empirical data of technological innovation to various types of investment. The model reveals a regular relationship between patents, R&D funding, and growing markets across technologies, and accurately predicts patenting rates at different stages of technological maturity and market development. We show quantitatively how growing markets have formed a vital complement to public R&D in driving innovative activity. These two forms of investment have each leveraged the effect of the other in driving patenting trends over long periods of time. PMID:24155867

  19. Quantitative Determination of Technological Improvement from Patent Data

    Science.gov (United States)

    2015-01-01

    The results in this paper establish that information contained in patents in a technological domain is strongly correlated with the rate of technological progress in that domain. The importance of patents in a domain, the recency of patents in a domain and the immediacy of patents in a domain are all strongly correlated with increases in the rate of performance improvement in the domain of interest. A patent metric that combines both importance and immediacy is not only highly correlated (r = 0.76, p = 2.6*10-6) with the performance improvement rate but the correlation is also very robust to domain selection and appears to have good predictive power for more than ten years into the future. Linear regressions with all three causal concepts indicate realistic value in practical use to estimate the important performance improvement rate of a technological domain. PMID:25874447

    Mastitis is an inflammation of mammary gland parenchyma that adversely affects bovine health and dairy production worldwide despite significant efforts to eradicate it. The aim of this work was to characterize the antimicrobial activity of 7-epiclusianone (7-epi), a compound extracted from the Rheedia brasiliensis fruit, its complex with copper against Streptococcus spp. isolated from bovine mastitis, and to assess their cytotoxicity to bovine mammary alveolar cells (MAC-T). The complex 7-epiclusianone-Cu (7-epi-Cu) was an amorphous green solid with optical activity. Its vibrational spectrum in the infrared region showed absorption bands in the high-frequency region, as well as bands that can be attributed to the unconjugated and conjugated stretching of the free ligand. The complex was anhydrous. One of the tested bacterial strains was not sensitive to the compounds, while the other three had MIC values of 7.8 µg mL -1 and minimum bactericidal concentration (MBC) values between 15.6 and 31.3 µg mL -1 . These two compounds are bacteriostatic, did not cause damage to the cell wall and, at sub-inhibitory concentrations, did not induce bacterial adhesion. The compounds were not cytotoxic. Based on these results, 7-epi and 7-epi-Cu exhibited desirable antimicrobial properties and could potentially be used in bovine mastitis treatment.

    Full Text Available Studies of small and medium-sized enterprise (SMEs development around the world show that the most significant factor for increasing their numbers and improving business success is the free enterprise, as exogenous, and innovation as an endogenous variable. At the same time, the dominant view in economic theory is that innovation is a key generator of changes for which the SMEs can be considered as a kind of metaphors for a successful business over the last twenty years in a number of economies. Arguing that cooperation between SMEs is increasingly common generic strategy of their development, the paper first explains the importance of collaboration to increase innovation and competitiveness, and then provides possible models using information technology such as Workflow Management Systems (WfMS, Service Oriented Architecture (SOA and Service-Oriented Cloud Computing Architecture (SOCCA to support the collaboration of these business entities. Solutions provided are aimed at improving the innovativeness of SMEs and fully follow the requirements of the so-called fifth-generation innovation process whose key attributes are integration and flexibility.

  12. Mount Sinai leverages smartphone technology, aiming to boost care, coordination of ED patients while also trimming costs.

    Science.gov (United States)

    2015-05-01

    Mount Sinai Hospital in New York, NY, is using smartphone technology to enhance follow-up calls to senior patients who have visited the ED, and to help provide acute-level care to select patients in their own homes. Investigators are hoping to show that these approaches can improve care and coordination while trimming costs, and they expect that patients will approve of these new approaches as well. While senior patients are still in the ED, nurse coordinators will work with them to load a HIPAA-compliant application to their smartphones so they can conduct face-to-face follow-up calls that meet HIPAA standards. Nurses say the face-to-face communications enhance their ability to assess how patients are doing following their ED visit. The hospital is also testing a program that enables some ED patients who meet inpatient criteria to receive this care in the home setting through the use of a mobile acute care team (MACT). In the case of emergencies, the MACT team relies on community paramedics who will visit the patients' homes and provide care under the direction of MACT physicians who are linked in to these visits via smartphone technology.

    2014-03-01

    Tumor size based on mammographic and ultrasound data are two methods used in predicting recurrence in breast cancer patients. Which technology offers better determination of diagnosis is an ongoing debate among radiologists, biophysicists, and other clinicians, however. Further complications in assessing the performance of each technology arise from missing data. One approach to remedy this problem may involve multiple imputation. Here, we therefore examine how imputation affects our assessment of the relationship between recurrence and tumor size determined either by mammography of ultrasound technology. We specifically employ the semi-parametric approach for imputing mixed continuous and binary data as presented in Helenowski and Demirtas (2013).

    2017-03-01

    Studies of determinants of adoption of new medical technology have failed to coalesce into coherent knowledge. A flaw obscuring strong patterns may be a common habit of treating a wide range of health care innovations as a generic technology. We postulate three decisional systems that apply to different medical technologies with distinctive expertise, interest, and authority: medical-individualistic, fiscal-managerial, and strategic-institutional decisional systems. This review aims to examine the determinants of the adoption of medical technologies based on the corresponding decision-making system. We included quantitative and qualitative studies that analyzed factors facilitating or inhibiting the adoption of medical technologies. In total, 65 studies published between 1974 and 2014 met our inclusion criteria. These studies contained 688 occurrences of variables that were used to examine the adoption decisions, and we subsequently condensed these variables to 62 determinants in four main categories: organizational, individual, environmental, and innovation-related. The determinants and their empirical association with adoption were grouped and analyzed by the three decision-making systems. Although we did not identify substantial differences across the decision-making systems in terms of the direction of the determinants' influence on adoption, a clear pattern emerged in terms of the categories of determinants that were targeted in different decision-making systems.

    Full Text Available Highly unsaturated fatty acids (HUFA, especially eicosapentaenoic acid (EPA and docosahexaenoic acid (DHA have long been recognized for its beneficial effect for human health and development.   The D6 fatty acid desaturase is generally considered to be the rate-limiting factor in HUFA biosynthesis.  Here, as the first step of study, we conducted experiment to select an appropriate construct that allows higher expression levels of masu salmon (Oncorhynchus masou D6-desaturase gene in zebrafish (Danio rerio in order to increase its activity for synthesizing EPA/DHA.  Salmon D6-desaturase cDNA (sD6 was separately ligated with human cytomegalovirus (hCMV, medaka elongation factor 1a (mEF1a and medaka b-actin (mAct promoters.  The resulted construct was designated as hCMV-sD6, mEF1a-sD6 and mAct-sD6, respectively.  Each of the constructs in circular DNA form was microinjected into 1-cell stage embryos at a concentration of 30mg/ml. Transgenic individuals were identified by polymerase chain reaction (PCR and their expression levels were analyzed by reverse transcription PCR.  The first (F1 and second (F2 generation was produced by crossing the transgenic founder F0 and F1, respectively, with wild-type fish.  The results showed that the highest transient gene expression level was obtained from the mAct-D6 construct, followed respectively by EF1a-D6 and hCMV-D6 construct. The transmission rate of transgene into F1 generation was 4.2%-44.1%, and into F2 was followed the Mendellian segregation pattern.   Expression of transgene in F2 generation was varied between strains regarding as the mosaics of F0 fish.  Now, a transgenic system to study the modification of fatty acid biosynthesis pathways in fish was established.  Further investigations are to produce fish containing higher levels of EPA and DHA.

  3. What next after determinism in the ontology of technology? Distributing responsibility in the biofuel debate.

    Science.gov (United States)

    Boucher, Philip

    2011-09-01

    This article builds upon previous discussion of social and technical determinisms as implicit positions in the biofuel debate. To ensure these debates are balanced, it has been suggested that they should be designed to contain a variety of deterministic positions. Whilst it is agreed that determinism does not feature strongly in contemporary academic literatures, it is found that they have generally been superseded by an absence of any substantive conceptualisation of how the social shaping of technology may be related to, or occur alongside, an objective or autonomous reality. The problem of determinism emerges at an ontological level and must be resolved in situ. A critical realist approach to technology is presented which may provide a more appropriate framework for debate. In dialogue with previous discussion, the distribution of responsibility is revisited with reference to the role of scientists and engineers.

    2017-10-01

    Full Text Available This study aims to examine the existence of several factors that determine the power of the adoption of production technology on micro souvenirs creative enterprise. The location of the research was determined purposely in Purbalingga Wetan Subdistrict, Purbalingga District, Central Java Province, Indonesia. Research respondents numbered 28 people. The results showed that the various determinants of the adoption of production technology have economic, social and environmental motives. The power of influence of each factor is also distinct. The adoption of different craftsmen resulted in the quality of souvenir products from coconut waste being unequal. Some have a motif design according to market trend. Product price level is feasible. However, some products are only produced semi-finished. The price of this product is relatively lower. The economic feasibility of craftsmen is closely related to the rate of adoption of production technology. There are small number (<25 percent of craftsmen use mechanical technology. The rest is still aided on the traditional manual techniques in processing waste coconut into souvenirs or creative handicraft.

  5. Using technology, choosing sex. The campaign against sex determination and the question of choice.

    Science.gov (United States)

    1992-01-01

    Women's groups and people's science and health groups formed the Forum Against Sex Determination and Sex Pre-Selection in November 1985 in Bombay, India, to prevent sex determination and sex preselection tests. The Forum considered sex determination and sex preselection to be an abuse of science and technology against people, especially women. Between 1901 and 1991, the sex ratio fell from 972 females/1000 males to 929/1000. The Forum saw the issue of sex determination and sex preselection as a link to oppression of and discrimination against females in all sectors of society. It also believed this to be a human rights issue. The Forum lobbied for a law regulating diagnostic techniques without banning them, since determining chromosomal abnormalities is important. The State of Maharashtra passed such a law in June 1988. It had some provisions which were counter-productive, however. For example, women undergoing a sex determination test must pay a fine of Rs 5 if found guilty of planning to terminate a pregnancy of a female fetus. Yet, neither the husband nor parents-in-law are liable, even though they often pressure women to undergo sex determination tests. The Forum's efforts and enactment of the law in Maharashtra have prompted other state governments and the central government to propose similar legislation. These state governments include Goa, Gujarat, and Orissa. The central government has met with organizations and individuals lobbying against misuse of diagnostic tests to obtain their counsel. The Forum does not feel comfortable with state control, however, since it tends to consider government to be against the people. Yet, the Forum did want the state to protect women's interests. It has raised important questions about technology, particularly concerning criteria to determine desirable and appropriate technologies.

    2010-01-01

    The development of information and communication technologies for design of environments for ageing is of great importance considering demographic trends in the future. There is a realistic hope for the preservation of self-determination and independence in the long term. However, some risks like a gradual loss of privacy should not be underestimated. The article discusses some ethical problems within this context. At the same time, the article demonstrates that the development and implementation of these technologies might be discussed for instance under some ethical assumptions of personal self-responsibility as well as social responsibility for the widest independence in advanced age.

  7. Rapid Determination of Optimal Conditions in a Continuous Flow Reactor Using Process Analytical Technology

    Directory of Open Access Journals (Sweden)

    Michael F. Roberto

    2013-12-01

    Full Text Available Continuous flow reactors (CFRs are an emerging technology that offer several advantages over traditional batch synthesis methods, including more efficient mixing schemes, rapid heat transfer, and increased user safety. Of particular interest to the specialty chemical and pharmaceutical manufacturing industries is the significantly improved reliability and product reproducibility over time. CFR reproducibility can be attributed to the reactors achieving and maintaining a steady state once all physical and chemical conditions have stabilized. This work describes the implementation of a smart CFR with univariate physical and multivariate chemical monitoring that allows for rapid determination of steady state, requiring less than one minute. Additionally, the use of process analytical technology further enabled a significant reduction in the time and cost associated with offline validation methods. The technology implemented for this study is chemistry and hardware agnostic, making this approach a viable means of optimizing the conditions of any CFR.

    Full Text Available Even though biogas technology has been introduced in Indonesia since 1990’s and having the potential, the rate of biogas adoption in Indonesia runs slowly. It is important to understand factors encouraging or discouraging potential adopters to build biogas plant. The development of livestock sector especially cattle farming in Indonesia can be seen as the opportunity to increase the rate of biogas adoption. This study investigated the factors affecting households of cattle farmer to adopt or not to adopt biogas technology. A cross-sectional research survey was carried out by using structured questionnaires as the primary tool to collect data from both biogas adopters and non biogas adopters in Pati regency, Indonesia. Socioeconomic characteristic of potential biogas adopters plays an important role to ensure the adoption of biogas technology sustainable. Socioeconomic characteristic regarding having high social status determines individual to adopt biogas relatively earlier than other members of a social system. Having high income and education enables traditional farmers to finance biogas plant by their own money or access aid from the government or other agencies. Among other attributes of innovation, relative advantage of installing biogas plant is the most determinant attribute to speed the rate of biogas adoption. Having biogas plant was perceived as better option and generated more benefits compared to previous technology or method.

    attitude structures, in order to manage the risks of mega-technologies, especially the risk of nuclear technology. Social surveys on people's attitudes toward nuclear power plants carried out in Japan showed that cognition of necessity and safety of them and fear of them had strong effects on the attitudes, and that the female had more negative attitudes than the male, and that people on administrative positions by occupation had most affirmative attitudes. However, there are few social survey researches that focus on the people's tendencies to zero-risk perception or comparative-risk perception to clarify the nature and determinants of attitude structures toward nuclear power technology. In this presentation we try to point out the factors which should be considered to manage the risks of mega-technologies in the social decision making processes by describing the survey data of zero-risk perception, comparative-risk perception, and over-sensibility to hazards relating to the attitude structures toward nuclear power technology.

    With the recent rapid economic growth, total energy demand in rural China has increased dramatically, and the energy structure is in the transition from non-commercial to commercial sources. Simultaneously, it is expected that households in rural areas will face energy shortages and additional environmental problems unless they have more access to renewable energy technologies. However, little is known about (i) the transition of energy use patterns and (ii) whether introduced technologies have been effective. To analyze these issues, we estimated the energy demands of rural households by using survey data taken from Beijing's ten suburban districts. The data contain information on both non-commercial and commercial energy use, key characteristics of the households and several renewable energy technologies. Our empirical analysis yielded three main results. First, the per capita income is a key factor in the per capita energy consumption. More specifically, the marginal increase (or marginal change) in per capita coal consumption strongly diminishes (or declines) as per capita income increases. Second, coal and liquefied petroleum gas (LPG) prices do not exhibit substitution effects, but an increase in these prices has strong negative effects on the use of these energy resources. Third, renewable energy technologies are identified to reduce coal consumption and to improve energy efficiency. Overall, these findings suggest a positive perspective: if the Chinese government were to design appropriate policies associated with renewable energy technologies and related energy prices, then coal consumption can be reduced in the near future, and the substitution to cleaner energy use will accelerate. Therefore, a smooth energy transition in rural China could be made in a more environmentally sustainable manner. - Highlights: ► Energy demands of non-commercial/commercial sources are examined in rural Beijing. ► Income and energy prices are key determinants of the energy

    This work presents a methodology to determine the off-cycle fuel economy benefit of a 2-Layer HVAC system which reduces ventilation and heat rejection losses of the heater core versus a vehicle using a standard system. Experimental dynamometer tests using EPA drive cycles over a broad range of ambient temperatures were conducted on a highly instrumented 2016 Lexus RX350 (3.5L, 8 speed automatic). These tests were conducted to measure differences in engine efficiency caused by changes in engine warmup due to the 2-Layer HVAC technology in use versus the technology being disabled (disabled equals fresh air-considered as the standard technology baseline). These experimental datasets were used to develop simplified response surface and lumped capacitance vehicle thermal models predictive of vehicle efficiency as a function of thermal state. These vehicle models were integrated into a database of measured on road testing and coupled with U.S. typical meteorological data to simulate vehicle efficiency across seasonal thermal and operational conditions for hundreds of thousands of drive cycles. Fuel economy benefits utilizing the 2-Layer HVAC technology are presented in addition to goodness of fit statistics of the modeling approach relative to the experimental test data.

    Full Text Available This paper analyzes the determinants of small and medium-sized enterprises’ technology adoption in the retail trade industry. From the theoretical perspective, two types of influential factors are differentiated in this respect: the personal characteristics of the manager/business owner and the business’s organizational characteristics. The empirical analysis is based on a survey of 268 small and medium-sized enterprises in the Spanish retail trade sector. A logistic regression specification is used as an econometric method. The results indicate that both the acquisition of new technical and electronic equipment and the obtaining of new software are affected by the two types of determinants previously pointed out. The manager/business owner’s entrepreneurial motivation and educational background have significant influences on technology adoption in this type of companies. Furthermore, being part of a business group, carrying out training activities for the employees and inter-firm cooperation also positively influence technology adoption in the retail trade industry.

    In resource-limited countries, CD4 T-cell (CD4) testing continues to be used for determining antiretroviral therapy (ART) initiation eligibility and opportunistic infection monitoring. To support expanded access to CD4 testing, simple and robust technologies are necessary. We conducted this study to evaluate the performance of a new Point-of-Care (POC) CD4 technology, the MyT4, compared to conventional laboratory CD4 testing. EDTA venous blood from 200 HIV-positive patients was tested in the laboratory using the MyT4 and BD FACSCalibur™. The MyT4 had an r2 of 0.82 and a mean bias of 12.3 cells/μl. The MyT4 had total misclassifications of 14.7% and 8.8% when analyzed using ART eligibility thresholds of 350 and 500 cells/μl, respectively. We conclude that the MyT4 performed well in classifying patients using the current ART initiation eligibility thresholds in Mozambique when compared to the conventional CD4 technology.

    To perform initial validation of a continuous motion monitoring technology that can potentially be used as a risk assessment tool to determine risk for developing pressure ulcers (PUs). We have used the EverOn system (Earlysense LTD, Ramat Gan, Israel) as a bed movement and activity monitor. The EverOn is a contactless continuous measurement system based on a piezoelectric sensor that is placed under the patient's mattress. The study was a noninterventional study performed in 2 medical departments in 2 medical centers. Recorded movement data from enrolled patients were retrospectively analyzed, and patients were assigned a motion level score. Motion scores for the first night of hospitalization were correlated with the Norton scale as calculated per patient on admission. Overall, 116 patients were included in the study from the 2 sites. Motion score was significantly different between the PU risk groups as determined by the Norton scale (10.7 ± 6.2 for low, 5.4 ± 4.9 for intermediate, and 1.6 ± 3.2 for high risk; P risk for developing PU (≤14), the sensitivity of the motion score was 85%, and the specificity was 93%. With regard to individual risk components, we found that activity, mobility, physical condition, and incontinence correlated highly with motion level. The high correlation between the EverOn motion score and the calculated Norton scale indicates the potential of this technology to serve as a risk assessment tool for the development of PUs.

    Near infrared reflectance spectroscopy technology, as a new analytic method, can be used to determine the content of lignin, cellulose and hemi-cellulose which is faster, effective, easier to operate, and more accurate than the traditional wet chemical methods. Nowadays it has been widely used in measuring the composition of lignocelluloses in woody plant and herbaceous plant. The domestic and foreign research progress in determining the lignin, cellulose and hemi-cellulose content in woody plant ( wood and bamboo used as papermaking raw materials and wood served as potential biomass energy) and herbaceous plant (forage grass and energy grass) by near infrared reflectance spectroscopy technology is comprehensively summarized and the advances in method studies of measuring the composition of lignocelluloses by near infrared reflectance spectroscopy technology are summed up in three aspects, sample preparation, spectral data pretreatment and wavelength selection methods, and chemometric analysis respectively. Four outlooks are proposed combining the development statues of wood, forage grass and energy grass industry. First of all, the authors need to establish more feasible and applicable models for a variety of uses which can be used for more species from different areas, periods and anatomical parts. Secondly, comprehensive near infrared reflectance spectroscopy data base of grass products quality index needs to be improved to realize on-line quality and process control in grassproducts industry, which can guarantee the quality of the grass product. Thirdly, the near infrared reflectance spectroscopy quality index model of energy plant need to be built which can not only contribute to breed screening, but also improve the development of biomass industry. Besides, modeling approaches are required to be explored and perfected any further. Finally, the authors need to try our best to boost the advancement in the determination method of lignin, cellulose and hemi

    Full Text Available Stripe rust caused by Puccinia striiformis f. sp. tritici (Pst is an important disease on wheat. In this study, quantitative determination of germinability of Pst urediospores was investigated by using near infrared reflectance spectroscopy (NIRS combined with quantitative partial least squares (QPLS and support vector regression (SVR. The near infrared spectra of the urediospore samples were acquired using FT-NIR MPA spectrometer and the germination rate of each sample was measured using traditional spore germination method. The best QPLS model was obtained with vector correction as the preprocessing method of the original spectra and 4000–12000 cm−1 as the modeling spectral region while the modeling ratio of the training set to the testing set was 4 : 1. The best SVR model was built when vector normalization was used as the preprocessing method, the modeling ratio was 5 : 1 and the modeling spectral region was 8000–11000 cm−1. The results showed that the effect of the best model built using QPLS or SVR was satisfactory. This indicated that quantitative determination of germinability of Pst urediospores using near infrared spectroscopy technology is feasible. A new method based on NIRS was provided for rapid, automatic, and nondestructive determination of germinability of Pst urediospores.

    Full Text Available Almost 150 years after that William Stanley Jevons published his paper The Coal Question (Jevons, 1866 the debate on mineral depletion has been ongoing between two main schools of thought: one that sees depletion as an important problem for the near future and another that sees technology and human ingenuity as the most important factors in making depletion a problem for the remote future. Today, however, we have created intellectual tools that permit us to frame the problem on the basis of physical factors, in particular on the basis of thermodynamics. The present paper examines the problem of mineral depletion from a broad viewpoint, with a specific view on the role of energy in the mining and production processes. The conclusion is that energy is a fundamental factor in determining how long we can expect the supply of mineral resources to last at the present prices and production levels. The rapid depletion of our main energy resources, fossil fuels, is creating a serious supply problem that is already being felt in terms of high prices of all mineral commodities. Technology can mitigate the problem, but not solve it. In a non remote future, the world's industrial system will have to undergo fundamental changes in order to adapt to a reduced supply of mineral commodities.

    Full Text Available The measurement of glycemia in subjects with renal failure, thus treated with hemodialysis, or peritoneal dialysis, is clinically relevant, since glucose levels may influence the determination of other solutes, such as creatinine, as well as some ions, such as sodium, whose degree of removal during dialysis sessions should be controlled carefully. Also, glucose levels should be controlled to avoid possible events of hypoglycemia during the treatment, especially in diabetic subjects. Indeed, even cases of hypoglycemic coma are documented. The glucose measurement during the dialysis treatment can be performed with different sensors and technologies: for instance, with traditional glucose meters, with instruments for continuous glucose monitoring, or with optical sensors. The aim of this review study was to analyze these different approaches and briefly discuss possible advantages and limitations.

    The purpose of this study is to determine the ontology of the concept of technology from the perspective of caring science. The aim is to increase knowledge of the concept in caring science and to answer the research question concerning what the concept of technology is in caring science. In literature, the concept of technology is used diversely referring it to caring technology, nursing technology, wellbeing technology, information technology, telenursing and technology in care named by a specific device or an area of nursing or medicine. The definition of the concept of technology and its ontology has not been determined from the viewpoint of caring science. Eriksson's model of concept determination provides a method to explore the ontology of the concept. This includes an etymological and semantic analysis as well as a determination of essence and basic category of the concept. The results showed that the concept of technology is multidimensional. It has evolved and altered over the centuries. The origin of the concept formulated from the Greek word 'techne', which has wider ontological dimensions. It is universal, it can be taught and it depends on the substance. Subsequently, the concept was introduced an ethical dimension, and it also developed more to the direction of engineering, mechanics and technical know-how. The semantic analysis revealed synonyms of the concept: art, equipment and knowledge. These introduced concepts such as craft, skill, treatment, engineering, science, study method and way. The nuances of the concept framed its nature. On the one hand, it stands out as practical and advanced, but on the other hand, it is difficult and conventional. The knowledge gained in this study will help to understand the phenomenon of technology in caring science. © 2014 Nordic College of Caring Science.

    Full Text Available Technology transfer has been a very frequent activity in the industrial world nowadays. Technology valuation, and in particular technology pricing, has played a considerable role in these transactions, in spite of a huge amount of limitations in the pricing methodologies applied. Making a sound, traceable and reliable means for applying the price evaluation procedure, seems as a technological requirement to be traced for. The objective of delivering this paper is to introduce a new numerical technology pricing method to provide the two transacting parties a unique compromised price. A three-dimensional model for technology pricing is proposed and The TOPSPS algorithm has been utilized to select the most similar technologies to the intended one and the constructed scoring system is applied to calculate the final technology price accordingly.

    Full Text Available The article is dedicated to one of the most important and urgent tasks in mechanical engineering development - the creation of low-density and environmentally-friendly thermoinsulation from available cheap basalt fibers for products to operate at temperatures up to 700°C.One of the most effective applications of such thermo-insulation is to develop and provide highly porous coatings from short basalt fibers by liquid filtration for tubing (T to supply superheated up to 420° C steam under pressure of 35 MPa in the deep layers with severe highviscosity oil. Tubing with the short low-density basalt insulation can be used for a greater depth than the vacuum-insulated tubing, which are also called "thermo-cases", and do not fully meet business needs for long-term reliability of oil vacuum tubes, too large mass per unit length of their design and, as a consequence, the impossibility to use such pipes for deep wells.The aim of the work is to simulate a liquid filtration process of short fibers and determine technological parameters of producing thermal insulation coatings of tubing pipes from basalt fibers and mineral binder shaped as cylinders and cylindrical shells. The paper proposes a mathematical model of free filtration deposition of short fibers from liquid slurry, which describes dynamics of creating thermal insulation products and allows us to determine the rational parameters of their manufacturing process. It shows methods to improve the products quality while forming the thermal insulation by filtration through additional vacuum deposition of a filtrate chamber and the final prepressing of sediment layer, giving dimensions and shape to the final product.The paper defines a prescription hydro mass composition. It shows that to increase the compressive strength of highly fibrous rings and cylindrical shells it is necessary to use based on oxide А12O3 5-7% by weight mineral binder, which fixes basalt fibers in places of their contacts.

    The problems of the existing methods for the determination of combining and technologically interlinked construction processes and activities are considered under the modern construction conditions of various facilities. The necessity to identify common parameters that characterize the interaction nature of all the technology-related construction and installation processes and activities is shown. The research of the technologies of construction and installation processes for buildings and structures with the goal of determining a common parameter for evaluating the relationship between technologically interconnected processes and construction works are conducted. The result of this research was to identify the quantitative evaluation of interaction construction and installation processes and activities in a minimum technologically necessary volume of the previous process allowing one to plan and organize the execution of a subsequent technologically interconnected process. The quantitative evaluation is used as the basis for the calculation of the optimum range of the combination of processes and activities. The calculation method is based on the use of the graph theory. The authors applied a generic characterization parameter to reveal the technological links between construction and installation processes, and the proposed technique has adaptive properties which are key for wide use in organizational decisions forming. The article provides a written practical significance of the developed technique.

  1. From Natural Monopoly to Public Utility: Technological Determinism and the Political Economy of Infrastructure in Progressive-Era America.

    Science.gov (United States)

    Plaiss, Adam

    In present-day debates regarding telecommunication policy, one frequently hears the terms natural monopoly and public utility. This article investigates the origins of these ideas, finding that Richard T. Ely-a celebrated American economist of the late nineteenth century-embedded in the term "natural monopoly" a narrative of technological determinism. By arguing that certain services had monopolizing tendencies hardwired into them, Ely argued for their regulation. Ely's theory of natural monopoly formed the basis of Wisconsin's 1907 public utilities law, which served as a model for many other states' regulatory policies. The modern notion of public utility thus carries with it the technological determinism of Ely's natural monopoly idea. By tracing the lineage of these two terms, this article recaptures the influence that activists and progressive politicians exercised over the formation of large technological systems during the Second Industrial Revolution.

    We reviewed 18 studies reporting on the use of microswitch technology to enable self-determined responding in children with profound and multiple disabilities. Identified studies that met pre-determined inclusion criteria were summarized in terms of (a) participants, (b) experimental design, (c) microswitches and procedures used, and (d) main results. The 18 studies formed three groups based on whether the microswitch technology was primarily intended to enable the child to (a) access preferred stimuli (7 studies), (b) choose between stimuli (6 studies), or (c) recruit attention/initiate social interaction (5 studies). The results of these studies were consistently positive and support the use of microswitch technology in educational programs for children with profound and multiple disabilities as a means to impact their environment and interact with others. Implications for delivery of augmentative and alternative communication intervention to children with profound and multiple disabilities are discussed.

  6. Determination of multi-GNSS pseudo-absolute code biases and verification of receiver tracking technology

    2017-04-01

    It is common to handle code biases in the Global Navigation Satellite System (GNSS) data analysis as conventional differential code biases (DCBs): P1-C1, P1-P2, and P2-C2. Due to the increasing number of signals and systems in conjunction with various tracking modes for the different signals (as defined in RINEX3 format), the number of DCBs would increase drastically and the bookkeeping becomes almost unbearable. The Center for Orbit Determination in Europe (CODE) has thus changed its processing scheme to observable-specific signal biases (OSB). This means that for each observation involved all related satellite and receiver biases are considered. The OSB contributions from various ionosphere analyses (geometry-free linear combination) using different observables and frequencies and from clock analyses (ionosphere-free linear combination) are then combined on normal equation level. By this, one consistent set of OSB values per satellite and receiver can be obtained that contains all information needed for GNSS-related processing. This advanced procedure of code bias handling is now also applied to the IGS (International GNSS Service) MGEX (Multi-GNSS Experiment) procedure at CODE. Results for the biases from the legacy IGS solution as well as the CODE MGEX processing (considering GPS, GLONASS, Galileo, BeiDou, and QZSS) are presented. The consistency with the traditional method is confirmed and the new results are discussed regarding the long-term stability. When processing code data, it is essential to know the true observable types in order to correct for the associated biases. CODE has been verifying the receiver tracking technologies for GPS based on estimated DCB multipliers (for the RINEX 2 case). With the change to OSB, the original verification approach was extended to search for the best fitting observable types based on known OSB values. In essence, a multiplier parameter is estimated for each involved GNSS observable type. This implies that we could

    Functional foods could differently affect human health in relation to the gender. Recent studies have highlighted the anti- Candida and anti- Chlamydia activities of some Lactobacillus strains isolated from the vagina of healthy women. Considering these important beneficial activities on women's health, the preparation of functional food containing active vaginal lactobacilli can represent a great scientific challenge for the female gender. In this context, the aim of this work was to study some functional and technological properties of 17 vaginal strains belonging to the species Lactobacillus crispatus, Lactobacillus gasseri , and Lactobacillus vaginalis in the perspective to include them in dairy products. The antagonistic activities against the pathogenic and spoilage species associated to food products and against the principal etiological agents of the genitourinary tract infections were evaluated. Moreover, the vaginal lactobacilli were characterized for their antibiotic resistance, and for their fermentation kinetics and viability during the refrigerated storage in milk. Finally, the volatile molecule profiles of the obtained fermented milks were determined. The results showed that several strains, mainly belonging to the species Lactobacillus crispatus , exhibited a significant antagonistic activity against spoilage and pathogenic microorganisms of food interest, as well as against urogenital pathogens. All the vaginal lactobacilli showed antimicrobial activity against strains belonging to the foodborne pathogenic species Listeria monocytogenes, Listeria innocua, Eenterococcus faecalis and Escherichia coli . In addition, most of the Lactobacillus strains were active toward the main pathogens responsible of vaginal and urinary tract infections including Staphylococcus aureus, Enterococcus faecium, Gardnerella vaginalis , and Proteus mirabilis .

    Spatial organization of chromatin plays an important role at multiple levels of genome regulation. On a global scale, its function is evident in processes like metaphase and chromosome segregation. On a detailed level, long-range interactions between regulatory elements and promoters are essential for proper gene regulation. Microscopic techniques like FISH can detect chromatin contacts, although the resolution is generally low making detection of enhancer-promoter interaction difficult. The 3C methodology allows for high-resolution analysis of chromatin interactions. 3C is now widely used and has revealed that long-range looping interactions between genomic elements are widespread. However, studying chromatin interactions in large genomic regions by 3C is very labor intensive. This limitation is overcome by the 5C technology. 5C is an adaptation of 3C, in which the concurrent use of thousands of primers permits the simultaneous detection of millions of chromatin contacts. The design of the 5C primers is critical because this will determine which and how many chromatin interactions will be examined in the assay. Starting material for 5C is a 3C template. To make a 3C template, chromatin interactions in living cells are cross-linked using formaldehyde. Next, chromatin is digested and subsequently ligated under conditions favoring ligation events between cross-linked fragments. This yields a genome-wide 3C library of ligation products representing all chromatin interactions in vivo. 5C then employs multiplex ligation-mediated amplification to detect, in a single assay, up to millions of unique ligation products present in the 3C library. The resulting 5C library can be analyzed by microarray analysis or deep sequencing. The observed abundance of a 5C product is a measure of the interaction frequency between the two corresponding chromatin fragments. The power of the 5C technique described in this chapter is the high-throughput, high-resolution, and quantitative way

    2017-05-01

    Full Text Available The high-speed development of industrial products and goods in the world has caused “technology” to be considered as a crucial competitive advantage for most large organizations. In recent years, developing countries have considerably tended to promote their technological and innovative capabilities through importing high-tech equipment owned and operated by developed countries. There are currently a variety of solutions to transfer a particular technology from a developed country. The selection of the most profitable technology transfer strategy is a very complex decision-making problem for technology importers as it involves different technical, environmental, social, and economic aspects. In this study, a hybrid multiple-criteria decision making (MCDM model based on the analytic hierarchy process (AHP and the technique for order of preference by similarity to ideal solution (TOPSIS is proposed to evaluate and prioritise various technology transfer strategies for wind turbine systems. For this purpose, a number of criteria and sub-criteria are defined from the viewpoint of wind energy investors, wind turbine manufacturers, and wind farm operators. The relative importance of criteria and sub-criteria with respect to the ultimate goal are computed using the eigenvalue method and then, the technology transfer alternatives are ranked based on their relative closeness to the ideal solution. The model is finally applied to determine the most suitable wind turbine technology transfer strategy among four options of reverse engineering, technology skills training, turn-key contracts, and technology licensing for the renewable energy sector of Iran, and the results are compared with those obtained by classical decision-making models.

    Full Text Available In the era of technological change, consumers face an environment increasingly complex, leading to significant challenges regarding buying and consuming choices and consumer protection. The most important and most influential technological changes in terms of the impact on the consumer, are iduced by internet, digitization and globalization. However, the era of technological change also means developing biotechnologies, nanotechnologies, new materials and new energy sources, all these changing people`s lives, living conditions, their needs and their behaviour as consumers. The literature highlights the factors that influence purchasing behaviour and changes manifested in terms of values, stressing the importance of promoting and protecting consumer`s rights and interests, The new responsible consumer can become a key driving force of sustainable development only if it is able to capitalize on new opportunities and to counter new risks of modern marketing technologies based on the Internet and mobile communications. This involves the assimilation of new knowledge throughout life to keep up with the accelerating pace of technological innovation and diffusion of e-commerce solutions and mobile commerce. We study the correlation between the composite index of consumer conditions and the level of participation in lifelong learning programmes in some Member States, based on secondary analysis of the data available at EU level,. The results confirm that the consumer`s situation is better in countries where the level of participation in lifelong learning programmes is higher. At the same time, however, the correlation is not linear. This shows that the consumer`s situation does not depend exclusively on formal continuing education but also other factors such as timeliness and severity of legal and institutional framework of consumer protection, the acquisition of knowledge through informal means, the requirement of different customers in different

    Most of the literatures related to university-industry (U-I) and technology transfer assume that the collaboration particularly the U-I joint research is beneficial to both university and industry which as a result underpins the sustainable development of economics and living standards of developed and developing countries. The U-I joint research for photovoltaic technology transfer in a developing country like Thailand should have been increased considering the fact that (i) the government implemented various strategies to support the renewable energy research and market development, (ii) the university aimed to be ''research-based university and (iii) the Thai photovoltaic industry struggle for competitiveness and survival in the global market. However, evidence revealed that the university and industry conducted little number of U-I joint projects. In this paper, we investigate the factors influencing the effective U-I joint research for photovoltaic technology transfer (UIJRPTT). In an attempt to better understand the influence of the factors, the path model with factors related to characteristics and perspectives of the university and the industry as well as joint research mechanism and their linkages to higher growth and improved economic and quality performance of the U-I joint research is developed and validated. The developed model empirically explains interaction between the factors and the outcome factors and can assist the government, the university and the industry to devise target strategies to improve the growth and performance of UIJRPTT.

    2016-12-01

    Full Text Available The problem of the development of pet food formulations in the conditions of information uncertainty which is characteristic of an actual business enterprise engaged in production of feed has been considered in the paper. The analysis of the literature [1–4] has shown that the main works are devoted to the extrusion of plastics and cereal products, with the temperature conditions equal to 130–200 ºC. This temperature range is not suitable for the production of pet food, and researches on this issue are virtually absent. This study is devoted to defining the functional and technological parameters of prescription mixture depending on the level of feed intake by unproductive animals; this knowledge will allow manufacturers to simplify the development of new formulations of balanced feed. Identification of this relationship has been carried out on the basis of modeling methods of mathematical statistics in Excel and Mathcad packages, as well as on the basis of fuzzy logic set theory in MatLAB package, as the construction of a complete mathematical model is complicated by absence of an explicit numerical form of the result received on the basis of sensory analysis. The research has revealed the dependence of feed intake level on functional and technological parameters of prescription mix for non-productive animals, in particular, the highest level of animal feed intake will be achieved at the following values of the main parameters: pH – 6.5; the moisture – 9 %; the protein concentration – 85 %; the particle size – 0.55 mm; the energy value – 267 kcal/100 g feed. The adequacy of the dependence for the input variables – the moisture feed and concentration of the protein component – is confirmed by the experimental investigations. This paper can be used to generate the optimal prescription composition for functional and technological characteristics of the samples in order to create balanced extruded feeds.

    This paper examines the factors affecting adoption of information and communication technologies (computers and the Internet) in Australian Indigenous households across three Indigenous communities, remote, rural and urban. Drawing on the sociological notion of structure and agency it is argued that being engaged in external fields influences Indigenous household ICT adoption. This paper develops a conceptual schema by drawing on Bourdieu's theory of habitus to explain the low uptake of ICTs in Indigenous households across Australia. Evidence suggests that there is more commonality across diverse communities than differences.

    The objectives of this study were to validate the application of Bluetooth technology to determine maternal pedigree and to determine ewe-lamb spatial relationships in extensive farming systems. A total of 35 first-cross Merino ewes (Merino × Border Leicester and East Friesian) and 23 of their lambs aged 1 to 3 wk were fitted with activity monitors equipped with Bluetooth (BT) technology (ActiGraph wGT3X-BT) by means of halters and collars, respectively. The BT devices on lambs were programmed to receive wireless signals once every minute from nearby BT units on ewes, which were programmed as beacons sending BT signals 4 times every second. Ewes and lambs fitted with sensors were dispatched into the paddocks, and after 10 d, the sensor units were retrieved and the BT signals received by lambs were downloaded using the ActiGraph software. The maternal pedigree of the lambs was determined as the ewe from which the lamb received the most BT signals. The distance between the lamb receiving the signal and the ewe sending the signal was estimated from the strength of BT signal received. The pedigree determined by BT was compared with the pedigree determined by DNA profiling and verification. The results showed that the accuracy of maternal pedigree determined by BT signals reached 100% within the first 15 min of returning animals to pasture of ewes and lambs fitted with sensors. Maternal signals (counts/d) received by 1-, 2-, and 3-wk-old lambs were 617 ± 102, 603 ± 54, and 498 ± 36, respectively, and the corresponding nonmaternal signals received were 140 ± 27, 106 ± 30, and 155 ± 39, respectively. Maternal signals received during the dark period were significantly higher than the maternal signals received during the light period ( < 0.05). Maternal signals received during the light period by 3-wk-old lambs were significantly lower when compared with those received by 1- and 2-wk-old lambs. Over 90% of the BT signals received from within 2 m of the lamb were from

    Interest in a science and technology career, and determinants of such interest, were investigated. In Study 1, self-efficacy for work activities and interest in a science and technology career were assessed. Participants were undergraduate students (n = 264; 132 men, 132 women) and graduates (n = 276; 146 men, 130 women). Graduates were more interested in a science and technology career than undergraduate students, and men were more interested in a technology career than women. Moreover, self-efficacy for realistic and investigative activities was positively related with interest in such a career. In Study 2, relationships between self-efficacy for realistic and investigative activities and childhood experiences were investigated using data from undergraduates (n = 262; 132 men, 130 women) and graduates (n = 274; 141 men, 133 women). Individuals who frequently experienced daily activities, activities in nature, and activities with animals and plants in their childhood had higher self-efficacy for realistic and investigative activities. Moreover, graduates had such past experiences more frequently than undergraduates and males more frequently than females.

    Full Text Available Soil erosion by water is a severe and continuous ecological problem in the north-western Highlands of Ethiopia. Limited perception of farmers to practice soil and water conservation (SWC technologies is one of the major causes that have resulted accelerated soil erosion. Therefore, this paper examines the major determinants of farmers’ perception to use and invest in SWC technologies in Ankasha District, north-western highlands of Ethiopia. A detailed field survey was carried out among 338 households, randomly selected from two rural sample kebeles (called villages here after. Descriptive statistics and logistic regression model were used to analyse the effects of multiple variables on farmers’ perception. The results indicate that educational level of the respondents and their access to trainings were found to have a positive and very significant association (P<0.01 with farmers’ perception. Likewise, land ownership, plot size, slope type, and extension contact positively and significantly influenced farmers’ perception at 5% level of significance. On the other hand, the influence of respondents’ age and plot distance from the homestead was found to be negative and significant (P<0.05. The overall results of this study indicate that the perception of farmers to invest in SWC technologies was highly determined by socioeconomic, institutional, attitudinal and biophysical factors. Thus, a better understanding of constrains that influence farmers' perception is very important while designing and implementing SWC technologies. Frequent contacts between farmers and extension agents and continues agricultural trainings are also needed to increase awareness of the impacts of SWC benefits.

    2017-03-01

    A multiplex competitive microimmunoassay for the simultaneous determination of gliadin, casein, β-lactoglobulin, and ovalbumin is presented. The assay in microarray format is performed on a DVD where the allergens are physisorbed on the polycarbonate surface of the disc. The immunointeraction is detected using a mixture of specific gold-labeled antibodies and the signal amplified with the silver enhancement method. The optical density of the precipitate, read by a DVD drive, is related to the concentration of the four allergens in sample. An optimized protocol for the simultaneous extraction of the allergen proteins from food samples is also addressed. The suitability of the method is demonstrated for the simultaneous quantitative extraction and determination of the targeted allergens in spiked baby foods, juices, and beers. The sensitivity (EC50) of the multiplexed assay was 0.04, 0.40, 0.08, and 0.16 mg L -1 for gliadin, casein, β-lactoglobulin, and ovalbumin, respectively, and the recovery results from the analysis of food samples ranged from 72 to 117%. A portable, easy-to-use, array-based bioanalytical method is developed for quantification of food allergens with a limit of detection below the accepted levels of the international legislations, which allows promotion of food safety and quality.

    The results of a feasibility study of blister-pack smart technology for monitoring medication adherence are reported. Research in the area of objective therapy compliance measurement has led to the development of microprocessor-driven systems that record the time a unit dose is removed from blister packaging. One device under development is the Smart Blister-a label imprinted with event-detection circuitry that can be affixed to standard commercial blister cards. In the first trial of the device in actual clinical practice, 115 community-dwelling Dutch patients receiving valsartan maintenance therapy (160 mg once daily) were given 14-day blister packages equipped with the Smart Blister. On the return of empty blister cards to the 20 participating community pharmacies, the stored information was scanned and downloaded for data analysis and patient counseling purposes. A total of 245 Smart Blister-equipped packages were used by valsartan recipients during the eight-month study. The device was largely effective in recording patient and blister-card identification data and other desired information. However, in 17% of cases, the Smart Blister system registered multiple tablet-removal events at the same time, presumably indicating unintentional breakage of nearby conductive circuits and the need for design refinements. The Smart Blister-equipped medication cards were generally well received by patients and pharmacies. An evaluation of the functionality and robustness of the Smart Blister in a real-world clinical practice situation yielded some promising results, but the findings also indicated a need for design refinements and additional performance testing of the device.

    Tetracyclines are widely used for both the treatment and prevention of diseases in animals as well as for the promotion of rapid animal growth and weight gain. This practice may result in trace amounts of these drugs in products of animal origin, such as milk and eggs, posing serious risks to human health. The presence of tetracycline residues in foods can lead to the transmission of antibiotic-resistant pathogenic bacteria through the food chain. In order to ensure food safety and avoid exposure to these substances, national and international regulatory agencies have established tolerance levels for authorized veterinary drugs, including tetracycline antimicrobials. In view of that, numerous sensitive and specific methods have been developed for the quantification of these compounds in different food matrices. One will note, however, that the determination of trace residues in foods such as milk and eggs often requires extensive sample extraction and preparation prior to conducting instrumental analysis. Sample pretreatment is usually the most complicated step in the analytical process and covers both cleaning and pre-concentration. Optimal sample preparation can reduce analysis time and sources of error, enhance sensitivity, apart from enabling unequivocal identification, confirmation and quantification of target analytes. The development and implementation of more environmentally friendly analytical procedures, which involve the use of less hazardous solvents and smaller sample sizes compared to traditional methods, is a rapidly increasing trend in analytical chemistry. This review seeks to provide an updated overview of the main trends in sample preparation for the determination of tetracycline residues in foodstuffs. The applicability of several extraction and clean-up techniques employed in the analysis of foodstuffs, especially milk and egg samples, is also thoroughly discussed. Copyright © 2018 Elsevier B.V.

    2017-05-01

    Full Text Available The impact of natural killer (NK cell alloreactivity on hematopoietic stem cell transplantation (HSCT outcome is still debated due to the complexity of graft parameters, HLA class I environment, the nature of killer cell immunoglobulin-like receptor (KIR/KIR ligand genetic combinations studied, and KIR+ NK cell repertoire size. KIR genes are known to be polymorphic in terms of gene content, copy number variation, and number of alleles. These allelic polymorphisms may impact both the phenotype and function of KIR+ NK cells. We, therefore, speculate that polymorphisms may alter donor KIR+ NK cell phenotype/function thus modulating post-HSCT KIR+ NK cell alloreactivity. To investigate KIR allele polymorphisms of all KIR genes, we developed a next-generation sequencing (NGS technology on a MiSeq platform. To ensure the reliability and specificity of our method, genomic DNA from well-characterized cell lines were used; high-resolution KIR typing results obtained were then compared to those previously reported. Two different bioinformatic pipelines were used allowing the attribution of sequencing reads to specific KIR genes and the assignment of KIR alleles for each KIR gene. Our results demonstrated successful long-range KIR gene amplifications of all reference samples using intergenic KIR primers. The alignment of reads to the human genome reference (hg19 using BiRD pipeline or visualization of data using Profiler software demonstrated that all KIR genes were completely sequenced with a sufficient read depth (mean 317× for all loci and a high percentage of mapping (mean 93% for all loci. Comparison of high-resolution KIR typing obtained to those published data using exome capture resulted in a reported concordance rate of 95% for centromeric and telomeric KIR genes. Overall, our results suggest that NGS can be used to investigate the broad KIR allelic polymorphism. Hence, these data improve our knowledge, not only on KIR+ NK cell alloreactivity in

    antennas closer than 20 cm. Regarding UHF (868 MHz) and microwave (2,45 GHz) reader devices it was demonstrated that exposure above the basic restriction is not to be expected as long as a minimum distance to the antennas of 10 cm - 20 cm is maintained. Concerning exposure from currently widest deployed Electronic Article Surveillance (EAS) technology also differences between technologies become obvious. While the numerous measurements and computations carried out did not give indications that radio frequency (RF)-EAS devices (operating frequency range typically 7,5-8,9 MHz) cause exposure above the basic restrictions defined in ICNIRP 1998, it could be demonstrated that for acoustomagnetic (AM)-EAS systems (operating frequency 58 kHz) exposure above the ICNIRP 1998 basic restrictions is possible, when approaching the antenna very closely, i.e., at unusual short distances of less than a few centimeters between the trunk and/or the head and the antenna. With respect to the assessment of the exposure caused by the RFID- and EAS devices with operating frequencies less than 10 MHz (particularly close to and below 100 kHz), it must be noted that the assessment summarized above was carried out based on the ICNIRP guidelines published in 1998, i.e., that the basic restriction in terms of current density was applied only to central nervous (CNS) tissue. It must be expected that the application of the new assessment concept recently published by ICNIRP 2010, which is based of induced electric field strength inside the tissue and which provides now also limits for all body tissues and not only for CNS tissue, may lead to significant different assessment results and conclusions for the mentioned device categories. Regarding possible electromagnetic interference with cardiac pacemakers, again RFID- and EAS-devices with working frequencies 58 kHz and 120 kHz and large (e.g., floor standing) antennas showed up to have the highest potential for interference compared to the other

    The aim of this study was to develop Near infrared (NIR) methods to determine the active content of non-coated pharmaceutical tablets manufactured from a proportional tablet formulation. These NIR methods intend to be used for the monitoring of the active content of tablets during the tableting process. Firstly, methods were developed in transmission and reflection modes to quantify the API content of the lowest dosage strength. Secondly, these methods were fully validated for a concentration range of 70-130% of the target active content using the accuracy profile approach based on β-expectation tolerance intervals. The model using the transmission mode showed a better ability to predict the right active content compared to the reflection one. However, the ability of the reflection mode to quantify the API content in the highest dosage strength was assessed. Furthermore, the NIR method based on the transmission mode was successfully used to monitor at-line the tablet active content during the tableting process, providing better insight of the API content during the process. This improvement of control of the product quality provided by this PAT method is thoroughly compliant with the Quality by Design (QbD) concept. Finally, the transfer of the transmission model from the off-line to an on-line spectrometer was efficiently investigated. Copyright © 2015 Elsevier B.V. All rights reserved.

    Haley, M.

    The purpose of this study was to investigate whether or not there have been successful applications of lean manufacturing principles in highly variable defense IT environments. Specifically, the study assessed if implementation of the lean philosophies by a defense organization yielded repeatable, predictable results in software release schedules reductions. Additionally, the study set out to determine what potential critical success factors (CSF's) were documented in the secondary data captured for each release, and extracted the variables used in the decision making for acceptability of fielding. In evaluating lean applicability to the high variability environment of USAF IT acquisitions, the research was conducted using non-experimental quantitative methods of archival secondary data. The sample for this case study was compiled from a USAF office that had implemented these techniques in pre-development, development and testing, and fielding phases. Based on the research data, acquisitionists and lean practitioners are inherently interconnected. Therefore, an understanding that critical success factors (CSFs) are integral to successful lean application in DoD IT acquisitions is crucial. Through a combination of synergistic alignments, plyometric CSFs were discovered to maximize the effects of each single CSF to produce rapid results in defense IT acquisitions. These include: (1) Enterprise Incorporation, (2) Team Trust, (3) Transformational Leadership, (4) Recursive Improvement, (5) Integrated Synergy, (6) Customer-Centric Culture and (7) Heuristic Communication.

    A method is proposed for the determination of selenium at low concentration in coal by collision/reaction cell technology inductively coupled plasma mass spectrometry (CRC-ICP-MS). Samples were decomposed by high pressure microwave-assisted wet digestion (MAWD) using 250 mg of coal, a mixture of 5 mL of 14.4 mol L-1 HNO3 and 1 mL of 40% HF and 70 min of heating program (200 °C and 40 bar). Hydrogen gas used in the collision/reaction cell was investigated to minimize the argon-based interferences at m/z 77, 78 and 80. The rejection parameter (RPq) and the H2 gas flow rate were set to 0.45 and 4.8 mL min-1, respectively. The use of H2 in the cell resulted in other polyatomic interferences, such as 76Ge1H+, 79Br1H+ and 81Br1H+, which impaired Se determination using 77Se, 80Se and 82Se isotopes, thus Se determination was carried out by monitoring only 78Se isotope. Selenium was determined in certified reference materials of coal (NIST 1635 and SARM 20) and an agreement better than 95% was observed between the results obtained by CRC-ICP-MS and the certified values. Under optimized conditions, the instrumental limit of detection was 0.01 μg L-1 and the method limit of detection was 0.01 μg g-1, which was suitable for Se determination at very low concentration in coal.

    We report on a lateral flow micro array that combines multi-spot immunochip technology and immunochromatography. It can serve as a tool for the simultaneous detection of multiple analytes. The test zone of the nitrocellulose support comprises a micro array spotted with up to 32 antigens that can capture labeled gold-antibodies after lateral flow. The detection limits and detectable concentration ranges of the assay were characterized. The method was applied to the determination of drugs of abuse (and their metabolites) in urine, specifically of morphine, amphetamine, methamphetamine, and benzoylecgonine. The assay format is rapid (10 min), and has both a low relative standard deviation ( -1 for drugs of abuse) are comparable to those of conventional single-analyte strip methods. (author)

The paper proposes: 1 determination and formulation of factors that influence the choice of rational method for joining re-bars of vertical support members of reinforced concrete frame; 2 determination of factor parameters; 3 ranging of factors by the expert evaluation (Delphi method. Methodology. In order to achieve research objectives, it is necessary to carry out analysis of existent rebar connection methods, determination of factors and parameter variation limits for each of the methods. Performing factor ranking by the expert evaluation method. Findings. The results of the questioning materials of 14 experts in the area of monolithic construction allowed setting the following: when choosing the rational re-bars connections, the most significant values are the factors that define the time parameters: possibility of carcassing, time of joining the re-bars, length of rebar cage, prior operation run time, operation time of main lifting equipment. Herewith the factors that define the rebar cage parameters have a direct relation to the work performance time, as they determine the amount of bar connections in the course of building erection over wide range. Economic factors – rebar connection cost and quality control cost – have the less value. It is obvious that in the conditions of considerable construction expenses it is advantageous for an investor to increase the rebar joining cost for the work growth rate. Structural and technological factors have the least value: origin of eccentric load transmission between re-bars, possibility of use of the thermally work-hardened re-bars of А500 and higher grades, work category for implementation of works, necessity to use the scaffold and appurtenances for re-enforcement of constructions. The reason is analogical: a contractor is ready to go to complication of technology with the purpose of reduction of the facility erection terms.

    Full Text Available Based on a survey of 505 corporate clients from the information technology industry, this study uses a logit statistical model to analyze whether such factors as loyalty, trust, client importance, intimacy between customer and supplier and the cost of changing suppliers may affect the choice of the marketing channel used by the client. The results show that the greater intimacy between a supplier and a corporate client is a determining factor for the client’s preference for being served by the manufacturer rather than an intermediary. In contrast, clients’ perception of their own importance to the supplier is not very relevant to their preference for being served directly by the manufacturer, and the other factors were not identified as (statistically important determinants of the choice of the marketing channel. These results suggest that the real advantage of the direct sales channel over the indirect sales channel lies in its ability to strengthen the client-manufacturer relationship, thereby contributing to the development of solutions that better serve the needs of corporate clients.

    Sodium-bearing waste (SBW) disposition is one of the U.S. Department of Energy (DOE) Idaho Operation Office’s (NE-ID) and State of Idaho’s top priorities at the Idaho National Engineering and Environmental Laboratory (INEEL). The INEEL has been working over the past several years to identify a treatment technology that meets NE-ID and regulatory treatment requirements, including consideration of stakeholder input. Many studies, including the High-Level Waste and Facilities Disposition Environmental Impact Statement (EIS), have resulted in the identification of five treatment alternatives that form a short list of perhaps the most appropriate technologies for the DOE to select from. The alternatives are (a) calcination with maximum achievable control technology (MACT) upgrade, (b) steam reforming, (c) cesium ion exchange (CsIX) with immobilization, (d) direct evaporation, and (e) vitrification. Each alternative has undergone some degree of applied technical development and preliminary process design over the past four years. This report presents a summary of the applied technology and process design activities performed through February 2004. The SBW issue and the five alternatives are described in Sections 2 and 3, respectively. Details of preliminary process design activities for three of the alternatives (steam reforming, CsIX, and direct evaporation) are presented in three appendices. A recent feasibility study provides the details for calcination. There have been no recent activities performed with regard to vitrification; that section summarizes and references previous work.

    Process Analytical Technology (PAT) is playing a central role in current regulations on pharmaceutical production processes. Proper understanding of all operations and variables connecting the raw materials to end products is one of the keys to ensuring quality of the products and continuous improvement in their production. Near infrared spectroscopy (NIRS) has been successfully used to develop faster and non-invasive quantitative methods for real-time predicting critical quality attributes (CQA) of pharmaceutical granulates (API content, pH, moisture, flowability, angle of repose and particle size). NIR spectra have been acquired from the bin blender after granulation process in a non-classified area without the need of sample withdrawal. The methodology used for data acquisition, calibration modelling and method application in this context is relatively inexpensive and can be easily implemented by most pharmaceutical laboratories. For this purpose, Partial Least-Squares (PLS) algorithm was used to calculate multivariate calibration models, that provided acceptable Root Mean Square Error of Predictions (RMSEP) values (RMSEP(API)=1.0 mg/g; RMSEP(pH)=0.1; RMSEP(Moisture)=0.1%; RMSEP(Flowability)=0.6 g/s; RMSEP(Angle of repose)=1.7° and RMSEP(Particle size)=2.5%) that allowed the application for routine analyses of production batches. The proposed method affords quality assessment of end products and the determination of important parameters with a view to understanding production processes used by the pharmaceutical industry. As shown here, the NIRS technique is a highly suitable tool for Process Analytical Technologies. Copyright © 2012 Elsevier B.V. All rights reserved.

    Extended exposure to sunlight may give rise to chemical and physical damages of human hairs. In this work, we report a novel method for non-destructive quantification of hair photodamage via multispectral imaging (MSI) technology. We show that the multispectral reflectance value in near-infrared region has a strong correlation with hair photodamage. More specifically, the hair segments with longer growing time and the same hair root segment after continuous ultraviolet (UV) irradiation displaying more severe photodamage observed via scanning electron microscopy (SEM) micrographs showed significantly higher multispectral reflectance value. Besides, the multispectral reflectance value of hair segments with different growing time was precisely reproduced by exposing the same hair root segment to specific durations of UV irradiation, suggesting that MSI can be adequately applied to determine the sunlight exposure time of the hair. The loss of cystine content of photodamaged hairs was identified to be the main factor that physiologically contributed to the morphological changes of hair surface fibers and hence the variation of their multispectral reflectance spectra. Considering the environmental information recording nature of hairs, we believe that MSI for non-destructive evaluation of hair photodamage would prove valuable for assessing sunlight exposure time of a subject in the biomedical fields.

    Full Text Available The leading national states in the tomato market are mainly Sinaloa and Jalisco. They determine the amount of production will sell in the country meanwhile smallholders depend about that decision to calculate the quantity of tomato they be able to place into local supply markets. Large producers invest in other aspects, such as in Information Technology Management (ITM, in order to obtain international and updated information they need for their strategic decision-making, as well as to establish effective communication with other producers, with suppliers and with customers. The question posed in the present investigation is: Will the lack of investment in ITM be a factor that affects the competitiveness of smallholders? This article has the objective to estimate the relevance of investing in the ITM, in order to increase the production through the application of the Cournot and Branding model; for two players who decide to sell simultaneously, resulting in two models: The first one, where the player 1 it will be a big producer who decides to invest in ITM to increase its market, while player 2 is a smallholder who does not have the capacity to invest in ITM. In the second resulting model, both players are big producers, who decide to invest in ITM to increase their market. In both models, we would be expected that the player who sells the most, whoever invests in ITM; however, as will be observed in the conclusions, investing in ITM is not always the solution to sell more.

    Full Text Available An extended version of the Technology Acceptance Model (TAM was applied by means of Structural Equation Modelling to testing various hypotheses on attitudes and intentions of dairy farmers towards three novel sustainable production strategies, as well as the influence of organic practices and collaborative behaviours, such as information sharing with supply-chain partners. Data on the acceptance of three sustainable production strategies, namely ‘Agro-forestry’, ‘Alternative protein source’, and ‘Prolonged maternal feeding’ were collected by a survey of dairy farmers in six European Union (EU countries (Austria, Belgium, Denmark, Finland, Italy, United Kingdom. We found that perceived usefulness is the key determinant of acceptance, while the intention to adopt a sustainable production strategy may derive from the influence of opinions (and behaviours of relevant others (e.g., leading dairy farmers, family members, advisors showing the role of interactions among farmers and other stakeholders in the adoption of innovations. Finally, the perceived usefulness of all of the investigated strategies is higher for organic farmers, while collaborative patterns reduce the impact of subjective norm on usefulness and overall acceptance. Our findings should encourage policy makers to consider the important role of supply chain management practices, including collaboration, to enhance the sustainability of dairy farming systems.

  10. Coupled Thermo-Mechanical and Photo-Chemical Degradation Mechanisms that determine the Reliability and Operational Lifetimes for CPV Technologies

    Dauskardt, Reinhold H. [Stanford Univ., CA (United States)

    2017-04-30

    This project sought to identify and characterize the coupled intrinsic photo-chemo-mechanical degradation mechanisms that determine the reliability and operational lifetimes for CPV technologies. Over a three year period, we have completed a highly successful program which has developed quantitative metrologies and detailed physics-based degradation models, providing new insight into the fundamental reliability physics necessary for improving materials, creating accelerated testing protocols, and producing more accurate lifetime predictions. The tasks for the program were separated into two focus areas shown in the figure below. Focus Area 1, led by Reinhold Dauskardt and Warren Cai with a primary collaboration with David Miller of NREL, studied the degradation mechanisms present in encapsulant materials. Focus Area 2, led by Reinhold Dauskardt and Ryan Brock with a primary collaboration with James Ermer and Peter Hebert of Spectrolab, studied stress development and degradation within internal CPV device interfaces. Each focus area was productive, leading to several publications, including findings on the degradation of silicone encapsulant under terrestrial UV, a model for photodegradation of silicone encapsulant adhesion, quantification and process tuning of antireflective layers on CPV, and discovery of a thermal cycling degradation mechanism present in metal gridline structures.

  11. Determinants and the perceived effects of adoption of sustainable improved food crop technologies by smallholder farmers along the value chain in Nigeria

    Full Text Available Adoption of improved agricultural technologies is fundamental to transformation of sustainable farming system, and a driving force for increasing agricultural productivity. This study provides empirical evidence on the determinants, and the perceived effects of adoption of improved food crop technologies in Nigeria. It is a cross-sectional survey of available technologies and 1,663 farm households in Nigeria. Data were analyzed with both descriptive and inferential statistics. The findings revealed very low technology adoption index. Available food crop production technologies used by sampled respondents were assessed as effective, appropriate, readily available, affordable, durable, user and gender friendly, with requisite skill to use them. However, processing technologies such as cabinet dryer were observed as unaffordable, not durable, not gender or users friendly. Packaging machines are also not users or gender friendly; washing machine not affordable, durable and gender friendly. Grain processing technologies like De-stoner, grading, and packaging machines are still not locally available and affordable. While parboilers have a negative impact on product quality, farmers’ health and the environment, tomato grinding machines have positive impact on the quality of the product, health of the users, yield and negatively affect the environment. The main determinants of adoption are the crop types, farm size and locations. Adoption of herbicide and inorganic fertilizer were influenced by travel cost to nearest place of acquisition, while the age of farmer has a positive and significant influence on the adoption of pesticide, water management and cassava harvester. Interestingly, male farmers only exhibit greater likelihood of adopting land preparation, inorganic and organic fertilizer technologies compared to their female counterpart. Therefore, policy options that consider all users at the development stages, favour reduction of travel cost

    2008-08-01

    This study explores different socio-economic and institutional factors influencing the adoption of improved soil conservation technology (ISCT) on Bari land (Rainfed outward sloping terraces) in the Middle Mountain region of Central Nepal. Structured questionnaire survey and focus group discussion methods were applied to collect the necessary information from farm households. The logistic regression model predicted seven factors influencing the adoption of improved soil conservation technology in the study area including years of schooling of the household head, caste of the respondent, land holding size of the Bari land, cash crop vegetable farming, family member occupation in off farm sector, membership of the Conservation and Development Groups, and use of credit. The study showed that technology dissemination through multi-sectoral type community based local groups is a good option to enhance the adoption of improved soil conservation technology in the Middle Mountain farming systems in Nepal. Planners and policy makers should formulate appropriate policies and programs considering the farmers’ interest, capacity, and limitation in promoting improved soil conservation technology for greater acceptance and adoption by the farmers.

    Risk-based approach is used for examination of impact of different factors on quality of medicinal products in technology transfer. A general diagram is offered for risk analysis execution in technology transfer from pharmaceutical development to production. When transferring technology to full- scale commercial production it is necessary to investigate and simulate production process application beforehand in new real conditions. The manufacturing process is the core factorfor risk analysis having the most impact on quality attributes of a medicinal product. Further importantfactors are linked to materials and products to be handled and manufacturing environmental conditions such as premises, equipment and personnel. Usage of risk-based approach in designing of multipurpose production facility of medicinal products is shown where quantitative risk analysis tool RAMM (Risk Analysis and Mitigation Matrix) was applied.

    2017-05-01

    Full Text Available Combining technologies for monitoring spatial behaviour of livestock with technologies that monitor pasture availability, offers the opportunity to improve the management and welfare of extensively produced beef cattle. The aims of the study were to investigate changes to beef cattle behaviour as pasture availability changed, and to determine whether Global Navigation Satellite System (GNSS technology could determine livestock grazing preference and hence improve pasture management and paddock utilisation. Data derived from GNSS collars included distance travelled and location in the paddock. The latter enabled investigation of individual animal interactions with the underlying Normalised Difference Vegetation Index (NDVI and pasture biomass of the paddock. As expected, there was a significant temporal decrease in NDVI during the study and an increase in distance travelled by cattle (P < 0.001; r2 = 0.88. The proportion of time budget occupied in grazing behaviour also increased (P < 0.001; r2 = 0.71. Cattle showed a partial preference for areas of higher pasture biomass/NDVI, although there was a large amount of variation over the course of the study. In conclusion, cattle behaviour changed in response to declining NDVI, highlighting how technologies that monitor these two variables may be used in the future as management tools to assist producers better manage cattle, to manipulate grazing intensity and paddock utilisation.

    2008-02-13

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

    New technology is changing the nature of gambling with interactive modes of gambling becoming putatively associated with higher rates of problem gambling. This paper presents the first nationally representative data on the prevalence and correlates of problem gambling among Australian adults since 1999 and focuses on the impact of interactive gambling. A telephone survey of 15,006 adults was conducted. Of these, 2,010 gamblers (all interactive gamblers and a randomly selected subsample of those reporting land-based gambling in the past 12 months) also completed more detailed measures of problem gambling, substance use, psychological distress, and help-seeking. Problem gambling rates among interactive gamblers were 3 times higher than for noninteractive gamblers. However, problem and moderate risk gamblers were most likely to attribute problems to electronic gaming machines and land-based gambling, suggesting that although interactive forms of gambling are associated with substantial problems, interactive gamblers experience significant harms from land-based gambling. The findings demonstrate that problem gambling remains a significant public health issue that is changing in response to new technologies, and it is important to develop strategies that minimize harms among interactive gamblers.

    No standard time or pharmacopoeia disintegration test method for orodispersible films (ODFs) exists. The USP disintegration test for tablets and capsules poses significant challenges for end-point determination when used for ODFs. We tested a newly developed disintegration test unit (DTU) against the USP disintegration test. The DTU is an accessory to the USP disintegration apparatus. It holds the ODF in a horizontal position, allowing top-view of the ODF during testing. A Gauge R&R study was conducted to assign relative contributions of the total variability from the operator, sample or the experimental set-up. Precision was compared using commercial ODF products in different media. Agreement between the two measurement methods was analysed. The DTU showed improved repeatability and reproducibility compared to the USP disintegration system with tighter standard deviations regardless of operator or medium. There is good agreement between the two methods, with the USP disintegration test giving generally longer disintegration times possibly due to difficulty in end-point determination. The DTU provided clear end-point determination and is suitable for quality control of ODFs during product developmental stage or manufacturing. This may facilitate the development of a standardized methodology for disintegration time determination of ODFs. © 2015 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci 104:3893-3903, 2015.

    Our laboratory has been developing and implementing a Real Time Radiological Warning Network around the Almaraz Nuclear Power Plant since 1990. It consists of six gamma dosimetry stations, two devices for the detection of radio-iodines and alpha, beta, and gamma emissions in air, a monitor for the continuous measurement of gamma radiation in water, and two basic meteorological stations. In this context, we have developed a mobile station endowed with a device for the measurement of dose rates which uses satellite positioning technology (GPS) so that it can be located remotely. The information gathered is sent back to our central laboratory in real/or deferred time through the digital mobile telephone network. A twofold utility is foreseen for this station: (a) action in the case of a radiological alert situation detected by our network, and (b) the performance of radiological-dosimetric studies of distant geographical zones.

The hypotheses were tested on a sample of 52 great male basketball players, aged 18 and 19. We deducted that most of the shots from the distance of 6.75 m occur under a entry angle greater than 42°, but not in the estimated interval (between 42° and 48°; that most of the shots do not occur in the estimated interval of the rotation of the ball (from 130 to 150 revolutions/minute; and that most of the shots do not occur in the estimated interval of the release time (< 0.7 seconds. When it comes to the consistency of the before mentioned parameters we did not find any discrepancies between the guards and other players. Based on the results a question arises: did the manufacturer of the measuring system adequately form the intervals of the aforementioned parameters or does the problem lie in the performance of the shots by the chosen players?.

  13. Recent progress, challenges and trends in trace determination of drug analysis using molecularly imprinted solid-phase microextraction technology.

    Ansari, Saeedeh; Karimi, Majid

    2017-03-01

    The quantification of drugs in biological samples is a significant task for determination of the physiological efficiency in evaluated drugs in the drug discovery. To analysis of the chemical compounds at the trace and ultratrace levels, adequate analytical procedures should be applied. Therefore, sample preparation method undoubtedly is the most important stage in the trace determination process. In spite of the great growth of analytical instrumentation during the recent years, sample preparation is still nowadays considered the impasse of the all analytical procedure, especially in drugs analysis. Because of the low concentration level of drugs in blood, plasma, and the diversity of the metabolites, the chosen extraction technique should be almost perfect. Solid-phase microextraction (SPME) is a powerful, simple, fast and an equilibrium-based sample preparation method that permits integration of sampling, sample clean-up, and pre-concentration in a single solvent-free step for chemical analysis. Molecularly imprinted polymers (MIPs) that provided by the presence of a template during their synthesis are the stable polymers with molecular recognition abilities and excellent materials which provide selectivity to sample preparation. Because of its characteristics such as easy preparation, high selectivity, and chemical stability, MIP is widely utilized in many analytical fields. Accordingly, the molecular imprinting and SPME methods combination would prepare a strong analytical instrumentation which comprises simplicity, flexibility, and the selectivity characteristics of both methods. This review focuses on the application of solid-phase microextraction method coupled with molecularly imprinted polymers, namely molecularly imprinted solid-phase microextraction (MISPME), for trace determination in drug analysis.

    2008-01-01

    X-ray Absorption Fine Structure spectroscopy was used to probe the speciation of the ppm level Pu in thirteen soil and concrete samples from the Rocky Flats Environmental Technology Site in support of the site remediation effort that has been successfully completed since these measurements. In addition to X-ray Absorption Near Edge Spectra, two of the samples yielded Extended X-ray Absorption Fine Structure spectra that could be analyzed by curve-fits. Most of these spectra exhibited features consistent with PU(IV), and more specificaJly, PuO{sub 2+x}-type speciation. Two were ambiguous, possibly indicating that Pu that was originally present in a different form was transforming into PuO{sub 2+x}, and one was interpreted as demonstrating the presence of an unusual Pu(VI) compound, consistent with its source being spills from a PUREX purification line onto a concrete floor and the resultant extreme conditions. These experimental results therefore validated models that predicted that insoluble PuO{sub 2+x} would be the most stable form of Pu in equilibrium with air and water even when the source terms were most likely Pu metal with organic compounds or a Pu fire. A corollary of these models' predictions and other in situ observations is therefore that the minimal transport of Pu that occurred on the site was via the resuspension and mobilization of colloidal particles. Under these conditions, the small amounts of diffusely distributed Pu that were left on the site after its remediation pose only a negligible hazard.

    2010-04-01

    To assess the reliability of high resolution intra-oral photostimulable storage phosphor (PSP) and complementary metal-oxide semiconductor (CMOS) imaging systems for working length (WL) assessment of small K-files in narrow and curved root canals. Eleven narrow and curved canals from extracted molars were used as pre-test for sample-size calculation. Nineteen canals from four cadavers were used for endodontic length assessment in the final study. Small K-files (ISO size 6, 8, and 10) were introduced into the canals at prepared length. Digital intra-oral radiographs were obtained using high-resolution Vistascan PSP plates and Sigma M CMOS active pixel sensor with a DC X-ray tube at 70 kV, 7 mA, and 0.16 s. Both image series were assessed with and without use of a dedicated endodontic filter. Three observers measured WLs for comparison to the gold standards of a digital millimeter ruler. Multiple regression analysis of the dependent measurements revealed no significant influence of imaging sensor (PSP or CMOS, p = 0.34) and image processing (p = 0.97). For ISO file size, however, there was a significant difference (p = 0.08) at a level of 10%. Observers mostly underestimated lengths using PSP but overestimated them on CMOS. Almost all radiographic measurements (96-98%) were within 2-mm deviation, while 71% to 82% deviated within 1 mm. Dedicated filtering and sensor type did not influence the outcome of WL determination of small file sizes when using high-resolution imaging sensors. WL determination with ISO file 6 did show a significant difference compared to ISO 8 and 10 but mostly for deviations <1.5 mm.

  19. Nuclear fuel technology - Tank calibration and volume determination for nuclear materials accountancy - Part 2: Data standardization for tank calibration

    International Nuclear Information System (INIS)

    2007-01-01

    Measurements of the volume and height of liquid in a process accountancy tank are often made in order to estimate or verify the tank's calibration or volume measurement equation. The calibration equation relates the response of the tank's measurement system to some independent measure of tank volume. The ultimate purpose of the calibration exercise is to estimate the tank's volume measurement equation (the inverse of the calibration equation), which relates tank volume to measurement system response. In this part of ISO 18213, it is assumed that the primary measurement-system response variable is liquid height and that the primary measure of liquid content is volume. This part of ISO 18213 presents procedures for standardizing a set of calibration data to a fixed set of reference conditions so as to minimize the effect of variations in ambient conditions that occur during the measurement process. The procedures presented herein apply generally to measurements of liquid height and volume obtained for the purpose of calibrating a tank (i.e. calibrating a tank's measurement system). When used in connection with other parts of ISO 18213, these procedures apply specifically to tanks equipped with bubbler probe systems for measuring liquid content. The standardization algorithms presented herein can be profitably applied when only estimates of ambient conditions, such as temperature, are available. However, the most reliable results are obtained when relevant ambient conditions are measured for each measurement of volume and liquid height in a set of calibration data. Information is provided on scope, physical principles, data required, calibration data, dimensional changes in the tank, multiple calibration runs and results on standardized calibration data. Four annexes inform about density of water, buoyancy corrections for mass determination, determination of tank heel volume and statistical method for aligning data from several calibration runs.

    The diffusion of health information technologies (HITs) within the health care sector continues to grow. However, there is no theory explaining how success of HITs influences patient care outcomes. With the increase in data breaches, HITs' success now hinges on the effectiveness of data protection solutions. Still, empirical research has only addressed privacy concerns, with little regard for other factors of information assurance. The objective of this study was to study the effectiveness of HITs using the DeLone and McLean Information Systems Success Model (DMISSM). We examined the role of information assurance constructs (ie, the role of information security beliefs, privacy concerns, and trust in health information) as measures of HIT effectiveness. We also investigated the relationships between information assurance and three aspects of system success: attitude toward health information exchange (HIE), patient access to health records, and perceived patient care quality. Using structural equation modeling, we analyzed the data from a sample of 3677 cancer patients from a public dataset. We used R software (R Project for Statistical Computing) and the Lavaan package to test the hypothesized relationships. Our extension of the DMISSM to health care was supported. We found that increased privacy concerns reduce the frequency of patient access to health records use, positive attitudes toward HIE, and perceptions of patient care quality. Also, belief in the effectiveness of information security increases the frequency of patient access to health records and positive attitude toward HIE. Trust in health information had a positive association with attitudes toward HIE and perceived patient care quality. Trust in health information had no direct effect on patient access to health records; however, it had an indirect relationship through privacy concerns. Trust in health information and belief in the effectiveness of information security safeguards increases

    The aim of this study was to validate a new method to measure regional myocardial perfusion reserve (MPR) with technetium-labelled tracers in patients with type 2 diabetes mellitus (DM2). A total of 40 consecutive DM2 patients without history of coronary artery disease (CAD) and 7 control subjects were recruited. Dipyridamole myocardial blood flow index (MBF) was assessed by measuring first transit counts in the pulmonary artery and myocardial count rate from gated SPECT images using {sup 99m}Tc-labelled tracers. The corresponding MBF index was estimated 2 h later according to the same procedure. Regional myocardial perfusion reserve (MPR) was defined as the ratio between dipyridamole and baseline MBF using a 17-segment left ventricular (LV) model. Coronary flow reserve (CFR) was estimated by transthoracic contrast echo Doppler monitoring of flow velocity in the left anterior descending coronary artery (LAD) during the same session. Estimated MPR was higher in control subjects than in patients (3.36 {+-} 0.66 vs 1.91 {+-} 0.61, respectively, p < 0.01). In patients, LAD CFR and LAD MPR were 2.01 {+-} 0.78 vs 1.93 {+-} 0.63, respectively (p = ns). The agreement between the two techniques was documented by their close correlation (r = 0.92, p < 0.001) and confirmed by the Bland-Altman analysis. Reversible perfusion defects occurred in 13 patients (32%) who showed similar MPR values as the remaining 27 (2.10 {+-} 0.71 vs 1.83 {+-} 0.71, respectively, p = ns). Finally, MPR was closely correlated with age (r = -0.50, p < 0.01) and time elapsed from the diagnosis of DM2 (r = -0.51, p < 0.01). LV regional MPR can be accurately estimated with the broadly available single photon technology. Application of this method to DM2 patients documents the presence of a microvascular dysfunction homogeneously distributed throughout the LV walls and most frequently not associated with reversible perfusion defects.

    The problem in the current debate on the accuracy of Karl Fischer (KF) titrations lies in the fact that coulometry is being compared to volumetry on mineral oil samples for which the true moisture content is unknown. To clarify this point, dehydrated oil samples equilibrated under known temperature and relative humidity conditions and equilibrated oil samples containing known amounts of added moisture were used to assess the accuracy of the determinations. In addition, the measurements were extended to other techniques given that it is unlikely that they would be affected by the same phenomenon causing the KF systematic errors. The samples sent to different laboratories were analyzed by headspace/capillary gas chromatography, gas-phase H2 sensor, oil-phase or gas-phase RH sensors, KF coulometric titration with direct or indirect injection, and KF volumetric titration using a standard or NIST modified procedure. The laboratory comparison showed that with the exception of 4 techniques out of 10 that were tested, the measurements gave results in the expected concentration range. Considering the exceptions, two techniques based on volumetric titration yielded results tainted with an important positive bias for both sample types. This bias, tentatively associated with the high iodine end point concentration used by these systems, was estimated at approximately 22 ppm under the conditions applied by NIST. On the other hand, the two RH sensors showed a marked tendency to underestimate the value of the samples containing high moisture content. In this case, a loss of analyte through wall adsorption during the time required to achieve steady-state conditions in the measuring chamber seems to be at the origin of the negative biases.

    Objectives The objectives of this study were to: 1) determine if a genetic algorithm in combination with morphing software can be used to evolve more attractive faces; and 2) evaluate whether this approach can be used as a tool to define or identify the attributes of the ideal attractive face. Study Design Basic research study incorporating focus group evaluations. Methods Digital images were acquired of 250 female volunteers (18–25 y). Randomly selected images were used to produce a parent generation (P) of 30 synthetic faces using morphing software. Then, a focus group of 17 trained volunteers (18–25 y) scored each face on an attractiveness scale ranging from 1 (unattractive) to 10 (attractive). A genetic algorithm was used to select 30 new pairs from the parent generation, and these were morphed using software to produce a new first generation (F1) of faces. The F1 faces were scored by the focus group, and the process was repeated for a total of four iterations of the algorithm. The algorithm mimics natural selection by using the attractiveness score as the selection pressure; the more attractive faces are more likely to morph. All five generations (P-F4) were then scored by three focus groups: a) surgeons (n = 12), b) cosmetology students (n = 44), and c) undergraduate students (n = 44). Morphometric measurements were made of 33 specific features on each of the 150 synthetic faces, and correlated with attractiveness scores using univariate and multivariate analysis. Results The average facial attractiveness scores increased with each generation and were 3.66 (+0.60), 4.59 (±0.73), 5.50 (±0.62), 6.23 (±0.31), and 6.39 (±0.24) for P and F1–F4 generations, respectively. Histograms of attractiveness score distributions show a significant shift in the skew of each curve toward more attractive faces with each generation. Univariate analysis identified nasal width, eyebrow arch height, and lip thickness as being significantly correlated with attractiveness

    To consider how staffing requirements have changed with evolving and increasingly more complex assisted reproduction technology (ART) laboratory practice. Analysis by four laboratory directors from three different ART programs of the level of complexity and time requirements for contemporary ART laboratory activities to determine adequate staffing levels. University-based and private ART programs. None. None. Human resource requirements for ART procedures. Both complexity and time required for completion of a contemporary ART cycle have increased significantly compared with the same requirements for the "traditional cycle" of the past. The latter required roughly 9 personnel hours, but a contemporary cycle can require up to 20 hours for completion. Consistent with this increase, a quantitative analysis shows that the number of embryologists required for safe and efficient operation of the ART laboratory has also increased. This number depends on not only the volume but also the types of procedures performed: the higher the number of complex procedures, the more personnel required. An interactive Personnel Calculator is introduced that can help determine staffing needs. The increased complexity of the contemporary ART laboratory requires a new look at the allocation of human resources. Our work provides laboratory directors with a practical, individualized tool to determine their staffing requirements with a view to increasing the safety and efficiency of operations. The work could serve as the basis for revision of the 2008 American Society for Reproductive Medicine (ASRM) staffing guidelines. Copyright © 2014 American Society for Reproductive Medicine.

    Title 3 of the 1990 Clean Air Act (CAA) Amendments addresses the emissions of 189 hazardous air pollutants (HAPs) and mandates that EPA develop technology-based [Maximum Achievable Control Technology (MACT)] standards for the control of these pollutants from approximately 174 source categories. After implementation of technology-based standards, EPA is required to further evaluate ''residual risk'' from HAP emissions, and, if required, develop more stringent standards to protect human health and the environment with an ''adequate margin of safety''. Recognizing that EPA will be issuing risk-based regulations after MACT standards have been implemented, the US Department of Energy (DOE), Oak Ridge Operations Office (ORO) has conducted an evaluation of ambient air impacts of HAP emissions from its installations located on the Oak Ridge Reservation (ORR) near Oak Ridge, Tennessee. This report provides results of atmospheric dispersion modeling conducted to determine ambient air impacts of HAP emissions from facilities located on the ORR

    The determination of chromium ( 52 Cr), iron ( 56 Fe) and selenium ( 80 Se) isotopes in foodstuffs of animal origin has been performed by collision cell technology (CCT) mode using an inductively coupled plasma mass spectrometry (ICP-MS) as detector after closed vessel microwave digestion. To significantly decrease the argon-based interferences at mass to charge ratios (m/z): 52 ( 40 Ar 12 C), 56 ( 40 Ar 16 O) and 80 ( 40 Ar 40 Ar), the gas-flow rates of a helium and hydrogen mixture used in the hexapole collision cell were optimised to 1.5 ml min -1 H 2 and 0.5 ml min -1 He and the quadrupole bias was adjusted daily between -2 and -15 mV. Limits of quantification (LOQ) of 0.025, 0.086 and 0.041 mg kg -1 for Cr, Fe and Se, respectively, in 6% HNO 3 were estimated under optimized CCT conditions. These LOQ were improved by a factor of approximately 10 for each element compared to standard mode. Precision under repeatability, intermediate precision reproducibility and trueness have been tested on nine different certified reference materials in foodstuffs of animal origin and on an external proficiency testing scheme. The results obtained for chromium, iron and selenium were in all cases in good agreement with the certified values and trueness was improved, compared to those obtained in standard mode

    The determination of arsenic ({sup 75}As) was studied using an ICP-MS equipped with collision cell technology (CCT). Different mixtures of gases (He and H{sub 2}) were tested using HCl conditions and a He flow rate of 4 mL min{sup -1} was found to be suitable for the removal of the poly-atomic spectral interference [{sup 40}Ar{sup 35}Cl]{sup +}. Trueness of the optimised method has been evaluated in both standard and CCT modes on six certified reference materials in foodstuffs of animal origin and on three external proficiency testing schemes (FAPAS). The results obtained generally coincided with the certified values, except for CCT mode in some categories of samples (meat, mussels and milk powder), for which a positive bias on results was observed due to the formation of poly-atomic interferences within the collision cell. The main interferences were studied and their contributions estimated. [{sup 58}Fe{sup 16}O{sup 1}H]{sup +} and [{sup 74}Ge{sup 1}H]{sup +} were the most significant interferences formed in the cell. Finally, different parameters (e.g. hexapole and quadrupole bias voltage, nebuliser gas flow) were optimised to try to attenuate these interferences.

    The aim of this paper is to develop a conceptual framework that would be used in determining the factors that influence the behavioral intention to use electronic collection system in federal government owned hospitals in Nigeria. The framework is supported by Technology Acceptance Model (TAM) as the underlying theory of the study. Past literature on individual user intention were thoroughly reviewed and found that TAM is fit appropriate in explaining the phenomenon under study. Based on the reviewed literature, it is expected that perceived usefulness and perceived ease of use will influence the intention of users (employees) to use e-collection system in the performance of their job tasks in Nigerian federal hospitals. In other words, users with higher perception on the system's usefulness and its ease of use are more likely to express their interest and willingness to use the system. In addition, the study has extended TAM with facilitating conditions construct and the research is expected to discover the level of its influence on behavioral intention to use e-collection system.

    2010-01-01

    We estimate firms' probability of technological adoption based on a firm level panel data set from four major sectors in Sweden between 2000 and 2003. Technological adoption is measured by environmental protection investments (EPI), and we focus particularly on differences between the decisions to adopt end of pipe solutions and clean technologies. We find that there seem to be different drivers for investments in end of pipe solutions and clean technologies, in particular we show that the probability of a firm investing in clean technologies to reduce emissions to air increases if the firm has expenditures for R and D related to environmental protection (green R and D), while price on energy is important for the investment in end of pipe solutions. Furthermore, our results indicate complementarity between the two types of technologies.

    Is there any relationship between estrogen and progesterone concentrations during assisted reproductive technology (ART)? Which hormone is the main determinant of impaired endometrial receptivity? This study was conducted from July to December 2016 at the in vitro Fertilization/Intracytoplasmic Sperm Injection unit at Zeynep Kamil Women and Children's Health Training and Research Hospital. A total of 289 women who underwent ART were prospectively screened and areas under the curve of temporal estrogen (AUCEM) and progesterone measurements (AUCPM) were calculated for each participant. Women were included if they had regular menstrual cycles, normal serum prolactin levels and had not received hormone treatment within three months. ART was indicated in all patients for unexplained infertility. Patients were divided into two groups: with (n = 90) and without (n = 199) embryo implantation. The relationship between the two AUCs and ART success was assessed in terms of embryo implantation and clinical pregnancy. Implantation was successful in 90 (31.1%) women, and a fetal heart rate was detected in 83 (28.7%) cases. There was a significant correlation between AUCEM and AUCPM (r = 0.525, P < 0.001). Multivariate regression analysis showed significant associations between failure of implantation, lack of clinical pregnancy and AUCEM (beta coefficient = 0.311, P < 0.001; beta coefficient = 0.297, P < 0.001, respectively) after adjusting for AUCPM. Our data showed that the degree of endometrial estrogen exposure is the main factor functioning as a detrimental effect of ovarian stimulation on endometrial receptivity. © 2017 Japan Society of Obstetrics and Gynecology.

    To investigate the perceived role of social technologies in promoting physical activity participation for young people with physical disabilities and to identify design considerations that should be addressed when creating social technologies to promote physical activity. Interactive design workshops for young people with physical disabilities aged 12-18 (n = 8) were held. Data were analyzed using interpretive thematic analysis. Young people perceived significant benefit for social technologies to promote physical activity as they have the potential to overcome many barriers to physical activity participation. Design features recommended by the participants included (1) options for diverse interests and preferences, (2) provision of informational support, (3) support through equitable technology design, (4) incentive through competition and play, and (5) opportunities to develop community. Social technology has potential to provide tailored, equitable opportunities for social engagement and physical activity participation for young people with physical disabilities through needs- and preference-specific design.

    Near-infrared calibration models were developed for the determination of content uniformity of pharmaceutical tablets containing 29.4% drug load for two dosage strengths (X and Y). Both dosage strengths have a circular geometry and the only difference is the size and weight. Strength X samples weigh approximately 425 mg with a diameter of 12 mm while strength Y samples, weigh approximately 1700 mg with a diameter of 20mm. Data used in this study were acquired from five NIR instruments manufactured by two different vendors. One of these spectrometers is a dispersive-based NIR system while the other four were Fourier transform (FT) based. The transferability of the optimized partial least-squares (PLS) calibration models developed on the primary instrument (A) located in a research facility was evaluated using spectral data acquired from secondary instruments B, C, D and E. Instruments B and E were located in the same research facility as spectrometer A while instruments C and D were located in a production facility 35 miles away. The same set of tablet samples were used to acquire spectral data from all instruments. This scenario mimics the conventional pharmaceutical technology transfer from research and development to production. Direct cross-instrument prediction without standardization was performed between the primary and each secondary instrument to evaluate the robustness of the primary instrument calibration model. For the strength Y samples, this approach was successful for data acquired on instruments B, C, and D producing root mean square error of prediction (RMSEP) of 1.05, 1.05, and 1.22%, respectively. However for instrument E data, this approach was not successful producing an RMSEP value of 3.40%. A similar deterioration was observed for the strength X samples, with RMSEP values of 2.78, 5.54, 3.40, and 5.78% corresponding to spectral data acquired on instruments B, C, D, and E, respectively.

  3. Nuclear fuel technology - Tank calibration and volume determination for nuclear materials accountancy - Part 6: Accurate in-tank determination of liquid density in accountancy tanks equipped with dip tubes

    International Nuclear Information System (INIS)

    2008-01-01

    ISO 18213 deals with the acquisition, standardization, analysis, and use of calibration data to determine liquid volumes in process tanks for accountability purposes. This part of ISO 18213 is complementary to the other parts, ISO 18213-1 (procedural overview), ISO 18213-2 (data standardization), ISO 18213-3 (statistical methods), ISO 18213-4 (slow bubbling rate), ISO 18213-5 (fast bubbling rate). The procedure described in this part of ISO 18213 is a two-step procedure. First, a liquid of known density is used to determine the vertical distance between the tips of the two probes (i.e. to calibrate their separation). The calibration step requires synchronous (or as nearly synchronous as possible) measurements of the pressure exerted at the tips of two probes by the calibration liquid in which they are submerged. The measurements obtained are used to make an accurate determination of probe separation. Second, the unknown density of the process liquid is determined with the aid of the probe separation calibration. The density-determination step also requires (nearly) synchronous measurements of the pressure exerted at the tips of two probes by the process liquid of unknown density. With careful technique, it is possible to make determinations of liquid density with in-tank measurements that approach the accuracy and precision of those made in the laboratory. Moreover, density determinations made with in-tank measurements are automatically made at the observed temperature of the tank liquid. Thus, no additional information about the liquid is required to infer its density at its tank temperature from determinations of its density at some other temperature. Except that the density of the process liquid is generally not well characterized, the steps involved in determining the height of process liquid in the tank are the same as those for determining the height of calibration liquid. Thus, the method of density determination given in this part of ISO 18213 is very

    Sodium bearing waste (SBW) disposition is one of the U.S. Department of Energy (DOE) Idaho Operation Office’s (NE-ID) and State of Idaho’s top priorities at the Idaho National Engineering and Environmental Laboratory (INEEL). Many studies have resulted in the identification of five treatment alternatives that form a short list of perhaps the most appropriate technologies for the DOE to select from. The alternatives are (a) calcination with maximum achievable control technology (MACT) upgrade, (b) steam reforming, (c) cesium ion exchange (CsIX) with immobilization, (d) direct evaporation, and (e) vitrification. Each alternative has undergone some degree of applied technical development and preliminary process design over the past four years. DOE desired further experimental data, with regard to steam reforming technology, to make informed decisions concerning selection of treatment technology for SBW. Mineralizing steam reforming technology, offered by THOR Treatment Technologies, LLC would produce a denitrated, granular mineral waste form using a high-temperature fluidized bed process. A pilot scale demonstration of the technology was performed in a 15-cm-diameter reactor vessel September 27 through October 1, 2004. The pilot scale equipment is owned by the DOE, and located at the Science and Technology Applications Research (STAR) Center in Idaho Falls, ID. Flowsheet chemistry and operational parameters were defined through a collaborative effort involving Idaho National Engineering and Environmental Laboratory, Savannah River National Laboratory (SRNL), and THOR Treatment Technologies personnel. Personnel from Science Applications International Corporation, owners of the STAR Center, operated the pilot plant. The pilot scale test was terminated as planned after achieving a total of 100 hrs of cumulative/continuous processing operation. About 230 kg of SBW surrogate were processed that resulted in about 88 kg of solid product, a mass reduction of about 62

    Health technology assessments (HTAs) are often difficult to conduct because of the decisive procedures of the HTA algorithm, which are often complex and not easy to apply. Thus, their use is not always convenient or possible for the assessment of technical requests requiring a multidisciplinary approach. This paper aims to address this issue through a multi-criteria analysis focusing on the analytic hierarchy process (AHP). This methodology allows the decision maker to analyse and evaluate different alternatives and monitor their impact on different actors during the decision-making process. However, the multi-criteria analysis is implemented through a simulation model to overcome the limitations of the AHP methodology. Simulations help decision-makers to make an appropriate decision and avoid unnecessary and costly attempts. Finally, a decision problem regarding the evaluation of two health technologies, namely, the evaluation of two biological prostheses for incisional infected hernias, will be analysed to assess the effectiveness of the model.

    The research is devoted to the scientific justification of metal processing by pressure with the help of thick monolithic plates forming (thickness 40 mm) from the V95 (analog 7475) (Al-Zn-Mg-Cu) and V-1461 (analog 2099) (Al-Cu-Li-Zn) alloys in creep and close-to-superplasticity. Optimum parameters of the technological process of plate forming are described. The effect of temperature on the magnitude of mechanical stresses (relaxation) during the tests of materials on pure bending is experimentally determined. Forming of thick plates (40 mm) on the UFP-1M unit, and the control of the obtained surface, in comparison with the given electronic model, made it possible to experimentally determine the time and number of forming stages. Mechanical properties of the material after the technological process and heat treatment are preliminary evaluated. The efficiency of using the obtained parameters of the technological process and treatment of metals by pressure in such methods in general is shown.

    ISO 18213 deals with the acquisition, standardization, analysis, and use of calibration to determine liquid volumes in process tanks for the accountancy of nuclear materials. This part of ISO 18213 is complementary to the other parts, ISO 18213-1 (procedural overview), ISO 18213-2 (data standardization), ISO 18213-3 (statistical methods), ISO 18213-5 (fast bubbling rate) and ISO 18213-6 (in-tank determination of liquid density). The procedure presented herein for determining liquid height from measurements of induced pressure applies specifically when a very slow bubbling rate is employed. A similar procedure that is appropriate for a fast bubbling rate is given in ISO 18213-5. Measurements of the volume and height of liquid in a process accountancy tank are often made in order to estimate or verify the tank's calibration or volume measurement equation. The calibration equation relates the response of the tank's measurement system to some independent measure of tank volume. Beginning with an empty tank, calibration data are typically acquired by introducing a series of carefully measured quantities of some calibration liquid into the tank. The quantity of liquid added, the response of the tank's measurement system, and relevant ambient conditions such as temperature are measured for each incremental addition. Several calibration runs are made to obtain data for estimating or verifying a tank's calibration or measurement equation. A procedural overview of the tank calibration and volume measurement process is given in ISO 18213-1. An algorithm for standardizing tank calibration and volume measurement data to minimize the effects of variability in ambient conditions that prevail during the measurement period is given in ISO 18213-2. The procedure presented in this part of ISO 18213 for determining the height of calibration liquid in the tank from a measurement of the pressure it induces in the tank's measurement system is a vital component of that algorithm.

    A rapid and reliable microwave extraction and the triple quadrupole-linear ion trap mass spectrometry method was developed and validated for the determination of eight alkaloids in Portulaca oleracea L. The optimal microwave extraction (MWE) condition was performed at 60 °C for 12 min with ethanol-water (70:30, v/v) as the extracting solvent, and the solvent to solid ratio was 30:1. The alkaloids were first detected simultaneously by electrospray ionization tandem mass spectrometry under positive-negative conversion multiple reaction monitor ((+/-)MRM) technique. With investigating three different columns, samples were separated in only 8 min on a Waters ACQUITY UPLC HSS T3 (50 × 2.1 mm(2), 1.8 μm) column using acetonitrile and formic acid-water solution as a mobile phase with a flow rate at 0.2 mL/min. All calibration curves showed good linearity (r>0.999) within the test ranges. The method developed was validated with acceptable sensitivity, intra- and inter-day precision, reproducibility, and extraction recoveries. It was successfully applied to the determination of eight alkaloids in Portulaca oleracea L. from different sources and different harvest periods. The method also provide a reference for extraction and determination of alkaloids in other complex systems. © 2013 Elsevier B.V. All rights reserved.

    A new selective and sensitive high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method was developed for the quantification of natamycin (NAT) in rabbit corneas with amphotericin B as the internal standard (IS). The cornea samples were processed by a simple and protective methanol soaking extraction technology. The NAT could be extracted completely from rabbit cornea after 24h of soaking with methanol under a mild condition. Chromatographic separation was performed on a C18 column (2.1mm×50mm, 3.5μm) using mobile phase with ammonium acetate buffer (pH 4.5; 4.0mM):acetonitrile (40:60, v/v) at a flow rate of 0.25ml/min. Quantification was performed using the transitions 666.2→503.2 m/z for NAT and 924.5→906.6 m/z for IS by positive ion electrospray ionization in multiple reaction monitoring mode. The assay was validated over a concentration range of 8.64ng/ml to 843ng/ml with lower limit of detection of 4.32ng/ml. The method was validated with respect to linearity, accuracy, precision, recovery, stability and extracting efficiency. The extraction recovery of NAT from cornea samples was approximately 100% with the new methanol soaking extraction procedure. The method has been successfully applied to the ocular pharmacokinetic studies of NAT eye drops in the cornea of Japanese white rabbit. Copyright © 2014 Elsevier B.V. All rights reserved.

  16. Climate-Determined Suitability of the Water Saving Technology "Alternate Wetting and Drying" in Rice Systems: A Scalable Methodology demonstrated for a Province in the Philippines.

    Directory of Open Access Journals (Sweden)

    Andrew Nelson

    Full Text Available 70% of the world's freshwater is used for irrigated agriculture and demand is expected to increase to meet future food security requirements. In Asia, rice accounts for the largest proportion of irrigated water use and reducing or conserving water in rice systems has been a long standing goal in agricultural research. The Alternate Wetting and Drying (AWD technique has been developed to reduce water use by up to 30% compared to the continuously flooded conditions typically found in rice systems, while not impacting yield. AWD also reduces methane emissions produced by anaerobic archae and hence has applications for reducing water use and greenhouse gas emissions. Although AWD is being promoted across Asia, there have been no attempts to estimate the suitable area for this promising technology on a large scale. We present and demonstrate a spatial and temporal climate suitability assessment method for AWD that can be widely applied across rice systems in Asia. We use a simple water balance model and easily available spatial and temporal information on rice area, rice seasonality, rainfall, potential evapotranspiration and soil percolation rates to assess the suitable area per season. We apply the model to Cagayan province in the Philippines and conduct a sensitivity analysis to account for uncertainties in soil percolation and suitability classification. As expected, the entire dry season is climatically suitable for AWD for all scenarios. A further 60% of the wet season area is found suitable contradicting general perceptions that AWD would not be feasible in the wet season and showing that spatial and temporal assessments are necessary to explore the full potential of AWD.

    Full Text Available Exact knowledge of femoral neck inclination and torsion angles is important in recognizing, understanding and treating pathologic conditions in the hip joint. However, published results vary widely between different studies, which indicates that there are persistent difficulties in carrying out exact measurements.A three dimensional modeling and analytical technology was used for the analysis of 1070 CT datasets of skeletally mature femurs. Individual femoral neck angles and torsion angles were precisely computed, in order to establish whether gender, age, body mass index and ethnicity influence femoral neck angles and torsion angles.The median femoral neck angle was 122.2° (range 100.1-146.2°, IQR 117.9-125.6°. There are significant gender (female 123.0° vs. male 121.5°; p = 0.007 and ethnic (Asian 123.2° vs. Caucasian 121.9°; p = 0.0009 differences. The median femoral torsion angle was 14.2° (-23.6-48.7°, IQR 7.4-20.4°. There are significant gender differences (female 16.4° vs. male 12.1°; p = 0.0001. Femoral retroversion was found in 7.8% of the subjects.Precise femoral neck and torsion angles were obtained in over one thousand cases. Systematic deviations in measurement due to human error were eliminated by using automated high accuracy morphometric analysis. Small but significant gender and ethnic differences were found in femoral neck and torsion angles.

    In separation process of multicomponent systems based on phase equilibrium is essential know the phase behavior and the critical points of the system for determination and optimization of the operational conditions. The experimental apparatus presents the challenge of determine the equilibrium phase dates of a system composed by petroleum residua and supercritical solvent. The used method, named acoustic method, allows the composition identification of the phases in equilibrium also in cloudy systems as they are the systems formed by residues of crude oil. For this reason, the acoustic methodology, based on the ultra-sound technology will be used in the study of the phase equilibrium and experimental characterization of the system, in benches scale, operating in severe conditions of temperature and pressure.The acoustic method is one not invasive and not subjective technique, what becomes the work in high pressures safer.

    2016-03-01

    Full Text Available Abstract Background Many people suffer from dry mouth (xerostomia due to radiotherapy treatment of head and neck cancer, diseases like Sjogren’s syndrome or as adverse effects to prescribed medications. Salivary substitute products like gels or sprays are often used for treatment. Efficacy of those oral care products are regularly assessed by validated or even not validated questionnaires. To determine the adhesion effect over time more objectively a new and sensitive method was established. The following study was designed to assess the dwell time of different oral care products in vitro. Method Two different types of surfaces were covered with oral care products and washed using a definite protocol with artificial saliva salt solution. First, oral care gels or oral care sprays were spread to a polystyrene surface of 2.25 cm2, then onto cell based three-dimensional gingiva models. The surfaces were washed ten times with artificial saliva salt solution. The resulting washing solutions were examined using mid infrared spectroscopy in order to detect ingredients of the oral care products. Results All assessed oral care gels or oral care sprays and their components were detected very sensitive. Even traces of the products were detected in the eluent and thus enabled to differentiate the dwell times of the different products. In general, the dwell time of oral care gels on polystyrene or gingiva models was longer than that of oral care sprays. The use of gingiva models improved the differentiation between different products. Conclusions MIR spectroscopy turned out to be a sensitive method to detect salivary substitutes. Differences between single components and different products can be detected. The described method is a simple, reliable and easy process to evaluate the dwell time of oral care products in vitro and thus a useful tool to design optimised salivary substitute products. Ethics This is an in vitro study. No ethics or consent was

    The qualitative and quantitative analysis on traditional Chinese medicine and formula components can be made by chemical and instrumental analysis methods. Of both, the instrumental analysis methods play a dominant role, including HPLC, HPLC-MS, HPLC-NMR, GC, GC-MS, biochemical and biological effect. But because traditional Chinese medicines and formula have complicated components, chemical methods are so unspecific that they shall be used less or with caution. While instrumental analysis methods are so specific that they are appropriate for analyzing complicated single component. The analysis techniques for multiple components of traditional Chinese medicines and formula focus on fingerprints, but all of these analysis techniques are limited by the pre-requisite of separation and the lack of general-purpose detectors and therefore being hard to realize the determination of all components of traditional Chinese medicines and formula. In the natural world, however, organisms identify native and alien components through specificity and non-specificity of clusters decided by antigens and antibodies. For example, components of traditional Chinese medicines are directly or indirectly synthesized into antigens and injected into animals, in order to generate specific antibodies and then collect cross reaction information of these components to specific antibodies. As for components without cross reaction, their contents shall be directly read out on the basis of the inhibition rate curve of competitive reaction for specificity of antigens and antibodies. Besides, a cross inhibition rate matrix shall be established first, and them a multiple regression linear equation between cross component concentration or concentration logarithm and inhibition rate by labeling the immunity competitive reaction between antibodies and haptens of traditional Chinese medicine and compound components, and then solved to obtain concentration of each component. The two results are combined to

For 232 Th and 238 U [determined at National Institute for Radiological Sciences (NIRS) by the ICP-MS)], Plant S feed coal (FC) sample that originated from China had the highest AC (15.77 ± 0.32 Bq/kg and 13.67 ± 0.82 Bq/kg, respectively), followed by Plant M FC sample also from China (8.31 ± 0.33 Bq/kg and 5.84 ± 0.12 Bq/kg, respectively), while Plants C and P FC samples that originated from the Philippines and Indonesia had the lowest ACs of 232 Th and 238 U. Plant S also had the highest bottom ash (BA) AC of 80.86 ± 3.23 Bq/kg and 100.20 ± 4.01 Bq/kg, respectively while Plant P had the highest fly ash (FA) AC of 155.96 ± 6.24 Bq/kg and 268.03 ± 10.72 Bq/kg, respectively. For AC's of 226 Ra, 228 Ra, 228 Th and 40 K determined by NIRS HPGe, Plant C had the highest in the FC sample (11.70 ± 1.39 Bq/kg, 13.65 ± 4.99 Bq/kg, 11.35 ± 3.96 Bq/kg ad 80.23 ± 10.91 Bq/kg, respectuvely). For AC's in the BA samples, Plant M had the highest 226 Ra (106.73 ± 6.74 Bq/kg) and Plant S had the highest 228 Ra and 40 K (66.64 ± 8.16 Bq/kg and 400.93 ± 43.06 Bq/kg, respectively For AC's in the FA samples, Plant S had the highest 226 Ra and 228 Ra AC's (131.13 ± 8.09 Bq/kg and 87.70 ± 10.45 Bq/kg, respectively) while Plant C had the highest 40 K AC (369.08 ± 40.87 Bq/kg). The highest AC enhancement of 238 U, 226 Ra ( 238 U series), 232 Th, 228 Ra, 228 Th ( 232 Th series) 40 K relative to feed coal occurred in Plant P FA sample, with 238 U showing the highest enhancement of 93.72 among the radionuclides.

    Full Text Available The paper analyses different attitudes towards technologies in contemporary philosophical discourses. It points out that classical notion of technology formulated by Martin Heidegger seems to be more and more often questioned and even forgotten. As a result, it is being replaced by the theory of determinism, according to which the change of technologies determines the changes in social systems, the human being including. This happens this way and not vice versa. Nowadays technē, or “technika” (in English: technology is mostly understood in the instrumental meaning or in the meaning of power. It is considered to be a powerful means, tool or mechanism to influence, change, control and manipulate human consciousness and human feelings. Despite the fact that technologies have already been tamed, the problem of huge responsibility for using and developing them arises. It is questioned whether the increasing society’s attention to modern technologies is not a particular “technology” of the postmodern capitalism to manipulate social consciousness. In parallel with “yes” answer to this question, Albert Borgmann’s idea that the causes of technological development have an ontological dimension, i.e. the causes are rooted in the nature of human beings themselves and their desire to adore own creativity, is discussed. Thus, it becomes necessary to probe deeper into the nature of creativity.

    The goal of this project was to identify and evaluate imaging technologies for observing juvenile fish within a Kaplan turbine, and specifically that would enable scientists to determine mechanisms of fish injury within an operating turbine unit. This report documents the opportunities and constraints for observing juvenile fish at specific locations during turbine passage. These observations were used to make modifications to dam structures and operations to improve conditions for fish passage while maintaining or improving hydropower production. The physical and hydraulic environment that fish experience as they pass through the hydroelectric plants were studied and the regions with the greatest potential for injury were defined. Biological response data were also studied to determine the probable types of injuries sustained in the turbine intake and what types of injuries are detectable with imaging technologies. The study grouped injury-causing mechanisms into two categories: fluid (pressure/cavitation, shear, turbulence) and mechanical (strike/collision, grinding/pinching, scraping). The physical constraints of the environment, together with the likely types of injuries to fish, provided the parameters needed for a rigorous imaging technology evaluation. Types of technology evaluated included both tracking and imaging systems using acoustic technologies (such as sonar and acoustic tags) and optic technologies (such as pulsed-laser videography, which is high-speed videography using a laser as the flash). Criteria for determining image data quality such as frame rate, target detectability, and resolution were used to quantify the minimum requirements of an imaging sensor.

    Research scope: The scope of the project is to study technological implementation processes by using Weick's sensemaking concept (Weick, 1995). The purpose of using a social constructivist approach to investigate technological implementation processes is to find out how new technologies transform...... patterns of social action and interaction in organisations (Barley 1986; 1990, Orlikowski 2000). Current research in the field shows that new technologies affect organisational routines/structures/social relationships/power relations/dependencies and alter organisational roles (Barley 1986; 1990, Burkhardt......, Orlikowski 2000). Viewing the use of technology as a process of enactment opens up for investigating the social processes of interpreting new technology into the organisation (Orlikowski 2000). The scope of the PhD project will therefore be to gain a deeper understanding of how the enactment of new...

    International Nuclear Information System (INIS)

    Chow, W.; Miller, M.J.; Fortune, J.; Behrens, G.; Rubin, E.

    1991-01-01

    The U.S. Environmental Protection Agency (EPA) has been regulating air toxics (hazardous air pollutants) under Section 112 of the 1970 Clean Air Act Amendments. To date, EPA has established emission standards for seven hazardous air pollutants. They include arsenic, asbestos, benzene, beryllium, mercury, vinyl chloride and radionuclides. EPA had determined that the low risks associated with electric utility fossil fuel power plant radionuclide emissions did not justify regulation under Section 112. The Clean Air Act Amendments of 1990 greatly expand EPA's rulemaking authority over toxic or hazardous air pollutants. The law lists 189 chemicals that would be subject to control. Sources that emit 10 tons/yr or more of any one pollutant, or 25 tons/yr or more of any combination thereof, must apply maximum available control technology (MACT). By definition, MACT is at least as stringent as best available control technology (BACT) for similar sources. However, consideration of the cost and feasibility of control, energy impacts and environmental factors will be given in MACT. Under the new amendments, the EPA will conduct a three-year study of the public health hazards from exposure to toxic emissions from utilities and report to Congress. EPA can regulate such emissions only if the regulations are appropriate based on this study. Two additional studies addressing mercury are also required. The first directs the EPA to conduct a four-year study of mercury emissions from electric utility steam generating units, municipal waste combustion units, and other sources. Included in this paper are evaluations of the rate and mass of such emissions, of health and environmental effects, and of the available control technologies and their costs

    The Miniature X-ray Solar Spectrometer (MinXSS) is a three-unit (3U) CubeSat designed for a three-month mission to study solar soft X-ray spectral irradiance. The first of the two flight models was deployed from the International Space Station in May 2016, and operated for one year before its natural deorbiting. This was the first flight of the Blue Canyon Technologies XACT 3-axis attitude determination and control system - a commercially available, high-precision pointing system. The performance of the pointing system on orbit was characterized, including performance at low altitudes where drag torque builds up. It was found that the pointing accuracy was 0.0042° - 0.0117° (15" - 42", 3σ, axis dependent) consistently from 190 km - 410 km, slightly better than the specification sheet states. Peak-to-peak jitter was estimated to be 0.0073° (10 s^-1) - 0.0183° (10 s^-1) (26" (10 s^-1) - 66" (10 s^-1), 3σ). The system was capable of dumping mome ntum until an altitude of 185 km. Small amounts of sensor degradation were found in the star tracker and coarse sun sensor. The mission profile did not require high-agility maneuvers, so it was not possible to characterize this metric. Without a GPS receiver, it was necessary to periodically upload ephemeris information to update the orbit propagation model and maintain pointing. At 400 km, these uploads were required once every other week; at ˜270 km, they were required every day. The power performance of the electric power system was also characterized, including use of a novel pseudo-peak power tracker - a resistor that limited the current draw from the battery on the solar panels. With 19 30% efficient solar cells and an 8 W system load, the power balance had 65% of margin on orbit. The current paper presents several recommendations to other CubeSat programs throughout.

    2017-01-01

    To date, not much is known about the psychological and motivational factors underlying technology use in late life. What are the interindividual determinants that lead older adults to invest in using technological innovations despite the age-related physiological changes that impose challenges on behavioral plasticity in everyday life? This research explores interindividual differences in subjective technology adaptivity - a general technology-related motivational resource that accounts for technology use in late life. More specifically, we investigate the influence of this factor relative to demographic characteristics, personality traits, and functional limitations in a longitudinal sample of community-dwelling older adults. We report results from a paper-and-pencil survey with 136 older adults between 59 and 92 years of age (mean = 71.4, SD = 7.4). Of those participants, 77 participated in a 2-year follow-up. We assessed self-reports of technology use, subjective technology adaptivity, functional limitations, and the personality traits openness to new experiences and neuroticism. Higher levels of subjective technology adaptivity were associated with technology use at the first measurement as well as increased use over the course of 2 years. Subjective technology adaptivity is a significant predictor of technology use in old age. Our findings contribute to improving the understanding of interindividual differences when using technological innovation in late life. Moreover, our findings have implications in the context of user involvement and may contribute to the successful development of innovative technology for older adults. © 2017 S. Karger AG, Basel.

    Sitorus, Hotna M.; Govindaraju, Rajesri; Wiratmadja, I. I.; Sudirman, Iman

    2016-02-01

    The success of a new technology depends on how well it is accepted by its intended users. Many technologies face the problem of low adoption rate, despite the benefits. An understanding of what makes people accept or reject a new technology can help speed up the adoption rate. This paper presents a framework for technology adoption based on an interactive perspective, resulting from a literature study on technology adoption. In studying technology adoption, it is necessary to consider the interactions among elements involved in the system, for these interactions may generate new characteristics or new relationships. The interactions among elements in a system adoption have not received sufficient consideration in previous studies of technology adoption. Based on the proposed interaction perspective, technology adoption is elaborated by examining interactions among the individual (i.e. the user or prospective user), the technology, the task and the environment. The framework is formulated by adopting several theories, including Perceived Characteristics of Innovating, Diffusion of Innovation Theory, Technology Acceptance Model, Task-Technology Fit and usability theory. The proposed framework is illustrated in the context of mobile banking adoption. It is aimed to offer a better understanding of determinants of technology adoption in various contexts, including technology in manufacturing systems.

    There is an increasing demand for analytical techniques able to measure so-called 'technology-critical elements', a set of chemical elements increasingly used in technological applications, in environmental matrices. Nowadays, inductively coupled plasma-mass spectrometry (ICP-MS) has become the technique of choice for measuring trace element concentrations. However, its application is often less straightforward than often assumed. The hints and drawbacks of ICP-MS application to the measurement of a set of less-studied technology-critical elements (Nb, Ta, Ga, In, Ge and Te) is discussed here and concise guidelines given.

    The authors reached the following conclusions: (1) The two-month evaluation of the MERCEM total mercury monitor from Perkin Elmer provided a useful venue in determining the feasibility of using a CEM to measure total mercury in a saturated flue gas. (2) The MERCEM exhibited potential at a mixed waste incinerator to meet requirements proposed in PS12 under conditions of operation with liquid feeds only at stack mercury concentrations in the range of proposed MACT standards. (3) Performance of the MERCEM under conditions of incinerating solid and liquid wastes simultaneously was less reliable than while feeding liquid feeds only for the operating conditions and configuration of the host facility. (4) The permeation tube calibration method used in this test relied on the CEM internal volumetric and time constants to relate back to a concentration, whereas a compressed gas cylinder concentration is totally independent of the analyzer mass flowmeter and flowrates. (5) Mercury concentration in the compressed gas cylinders was fairly stable over a 5-month period. (6) The reliability of available reference materials was not fully demonstrated without further evaluation of their incorporation into routine operating procedures performed by facility personnel. (7) The degree of mercury control occurring in the TSCA Incinerator off-gas cleaning system could not be quantified from the data collected in this study. (8) It was possible to conduct the demonstration at a facility incinerating radioactively contaminated wastes and to release the equipment for later unrestricted use elsewhere. (9) Experience gained by this testing answered additional site-specific and general questions regarding the operation and maintenance of CEMs and their use in compliance monitoring of total mercury emissions from hazardous waste incinerators.

    The United States Department of Energy (DOE) continually seeks safer and more cost-effective technologies for use in deactivation and decommissioning (D and D) of nuclear facilities. The Deactivation and Decommissioning Focus Area (DDFA) of the DOE's Office of Science and Technology (OST) sponsors large-scale demonstration and deployment projects (LSDDPs). At these LSDDPs, developers and vendors of improved or innovative technologies showcase products that are potentially beneficial to the DOE's projects and to others in the D and D community. Benefits sought include decreased health and safety risks to personnel and the environment, increased productivity, and decreased costs of operation. The Idaho National Engineering and Environmental Laboratory (INEEL) generated a list of statements defining specific needs and problems where improved technology could be incorporated into ongoing D and D tasks. One such need is to reduce the volume of waste copper wire and cable generated by D and D. Deactivation and decommissioning activities of nuclear facilities generates hundreds of tons of contaminated copper cable, which are sent to radioactive waste disposal sites. The Copper Cable Recycling Technology separates the clean copper from contaminated insulation and dust materials in these cables. The recovered copper can then be reclaimed and, more importantly, landfill disposal volumes can be reduced. The existing baseline technology for disposing radioactively contaminated cables is to package the cables in wooden storage boxes and dispose of the cables in radioactive waste disposal sites. The Copper Cable Recycling Technology is applicable to facility decommissioning projects at many Department of Energy (DOE) nuclear facilities and commercial nuclear power plants undergoing decommissioning activities. The INEEL Copper Cable Recycling Technology Demonstration investigated the effectiveness and efficiency to recycle 13.5 tons of copper cable. To determine the effectiveness

    Technological cycles have been characterized as the basis of long and continuous periods economic growth through sustained changes in total factor productivity. While this hypothesis is in part consistent with several theories of growth, the sheer magnitude and length of the economic revolutions experienced by humankind seems to indicate surmise that more attention should be given to the origin of major technological and economic changes, with reference to one crucial question: role of production and use of energy in economic development.

    The objective of this summer's work was to attempt to enhance Technology Application Group (TAG) ability to measure the outcomes of its efforts to transfer NASA technology. By reviewing existing literature, by explaining the economic principles involved in evaluating the economic impact of technology transfer, and by investigating the LaRC processes our William & Mary team has been able to lead this important discussion. In reviewing the existing literature, we identified many of the metrics that are currently being used in the area of technology transfer. Learning about the LaRC technology transfer processes and the metrics currently used to track the transfer process enabled us to compare other R&D facilities to LaRC. We discuss and diagram impacts of technology transfer in the short run and the long run. Significantly, it serves as the basis for analysis and provides guidance in thinking about what the measurement objectives ought to be. By focusing on the SBIR Program, valuable information regarding the strengths and weaknesses of this LaRC program are to be gained. A survey was developed to ask probing questions regarding SBIR contractors' experience with the program. Specifically we are interested in finding out whether the SBIR Program is accomplishing its mission, if the SBIR companies are providing the needed innovations specified by NASA and to what extent those innovations have led to commercial success. We also developed a survey to ask COTR's, who are NASA employees acting as technical advisors to the SBIR contractors, the same type of questions, evaluating the successes and problems with the SBIR Program as they see it. This survey was developed to be implemented interactively on computer. It is our hope that the statistical and econometric studies that can be done on the data collected from all of these sources will provide insight regarding the direction to take in developing systematic evaluations of programs like the SBIR Program so that they can

    The globalization of the economy and the end of the Cold War have triggered many changes in the traditional practices of U.S. industry. To effectively apply the resources available to the United States, the federal government has firmly advocated a policy of technology transfer between private industry and government labs, in this case the National Aeronautics and Space Administration (NASA). NASA Administrator Daniel Goldin is a strong proponent of this policy and has organized technology transfer or commercialization programs at each of the NASA field centers. Here at Langley Research Center, the Technology Applications Group (TAG) is responsible for facilitating the transfer of Langley developed research and technology to U.S. industry. Entering the program, I had many objectives for my summer research with TAG. Certainly, I wanted to gain a more thorough understanding of the concept of technology transfer and Langley's implementation of a system to promote it to both the Langley community and the community at large. Also, I hoped to become more familiar with Langley's research capabilities and technology inventory available to the public. More specifically, I wanted to learn about the technology transfer process at Langley. Because my mentor is a member of Materials and Manufacturing marketing sector of the Technology Transfer Team, another overriding objective for my research was to take advantage of his work and experience in materials research to learn about the Advanced Materials Research agency wide and help market these developments to private industry. Through the various projects I have been assigned to work on in TAG, I have successfully satisfied the majority of these objectives. Work on the Problem Statement Process for TAG as well as the development of the Advanced Materials Research Brochure have provided me with the opportunity to learn about the technology transfer process from the outside looking in and the inside looking out.

    The CEA is an organization with a primarily technological focus, and one of the key areas in which it carries out research is Health Technology. This field of research was recognized and approved by the French Atomic Energy Committee on July 20, 2004. The expectations of both the public and health care professionals relate to demands for the highest standards of health care, at minimum risk. This implies a need to diagnose illness and disease as accurately and as at early a stage as possible, to target surgery precisely to deal only with damaged organs or tissues, to minimize the risk of side effects, allergies and hospital-acquired infections, to follow-up and, as far as possible, tailor the health delivery system to each individual's needs and his or her lifestyle. The health care sector is subject to rapid changes and embraces a vast range of scientific fields. It now requires technological developments that will serve to gather increasing quantities of useful information, analyze and integrate it to obtain a full understanding of highly complex processes and to be able to treat the human body as un-invasively as possible. All the technologies developed require assessment, especially in the hospital environment. (authors)

    The development and application of new technologies in the United States has always been important to the economic well being of the country. The National Aeronautics and Space Administration (NASA) has been an important source of these new technologies for almost four decades. Recently, increasing global competition has emphasized the importance of fully utilizing federally funded technologies. Today NASA must meet its mission goals while at the same time, conduct research and development that contributes to securing US economic growth. NASA technologies must be quickly and effectively transferred into commercial products. In order to accomplish this task, NASA has formulated a new way of doing business with the private sector. Emphasis is placed on forming mutually beneficial partnerships between NASA and US industry. New standards have been set in response to the process that increase effectiveness, efficiency, and timely customer response. This summer I have identified potential markets for two NASA inventions: including the Radially Focused Eddy Current Sensor for Characterization of Flaws in Metallic Tubing and the Radiographic Moire. I have also worked to establish a cooperative program with TAG, private industry, and a university known as the TAG/Industry/Academia Program.

    2008-01-01

    Photovoltaics is already a billion dollar industry. It is experiencing rapid growth as concerns over fuel supplies and carbon emissions mean that governments and individuals are increasingly prepared to ignore its current high costs. It will become truly mainstream when its costs are comparable to other energy sources. At the moment, it is around four times too expensive for competitive commercial production. Three generations of photovoltaics have been envisaged that will take solar power into the mainstream. Currently, photovoltaic production is 90% first-generation and is based on silicon wafers. These devices are reliable and durable, but half of the cost is the silicon wafer and efficiencies are limited to around 20%. A second generation of solar cells would use cheap semiconductor thin films deposited on low-cost substrates to produce devices of slightly lower efficiency. A number of thin-film device technologies account for around 5-6% of the current market. As second-generation technology reduces the cost of active material, the substrate will eventually be the cost limit and higher efficiency will be needed to maintain the cost-reduction trend. Third-generation devices will use new technologies to produce high-efficiency devices. Advances in nanotechnology, photonics, optical metamaterials, plasmonics and semiconducting polymer sciences offer the prospect of cost-competitive photovoltaics. It is reasonable to expect that cost reductions, a move to second-generation technologies and the implementation of new technologies and third-generation concepts can lead to fully cost-competitive solar energy in 10-15 years.

    Full Text Available Investment in technology and human capital, and co-operation networks,appear to play an important role in the development of the innovative process of a country ; proof of this are the different perspectives on innovation, including the theory of endogenous development. With the information from the IV Survey for Technological Innovation and Development conducted in Colombiafor the 2007-2008 period, The authors used a method of linear regression that allows defining causal relationships among the variables mentioned above. The results establish that variables like technology, the relations of cooperation, and investment in human capital determine the innovative results of the Colombian manufacturing industry, finding that these results are greater when they establish cooperative relations with other entities that support innovation and when investment in human capital formation takes place.

    The technology activities carried out by the Euratom-ENEA Association in the framework of the European Fusion Development Agreement concern the Next Step (International Thermonuclear Experimental Reactor - ITER), the Long-Term Programme (breeder blanket, materials, International Fusion Materials Irradiation Facility - IFMIF), Power Plant Conceptual Studies and Socio-Economic Studies. The Underlying Technology Programme was set up to complement the fusion activities as well to develop technologies with a wider range of interest. The Technology Programme mainly involves staff from the Frascati laboratories of the Fusion Technical and Scientific Unit and from the Brasimone laboratories of the Advanced Physics Technologies Unit. Other ENEA units also provide valuable contributions to the programme. ENEA is heavily engaged in component development/testing and in design and safety activities for the European Fusion Technology Programme. Although the work documented in the following covers a large range of topics that differ considerably because they concern the development of extremely complex systems, the high level of integration and coordination ensures the capability to cover the fusion system as a whole. In 2004 the most significant testing activities concerned the ITER primary beryllium-coated first wall. In the field of high-heat-flux components, an important achievement was the qualification of the process for depositing a copper liner on carbon fibre composite (CFC) hollow tiles. This new process, pre-brazed casting (PBC), allows the hot radial pressing (HRP) joining procedure to be used also for CFC-based armour monoblock divertor components. The PBC and HRP processes are candidates for the construction of the ITER divertor. In the materials field an important milestone was the commissioning of a new facility for chemical vapour infiltration/deposition, used for optimising silicon carbide composite (SiCf/SiC) components. Eight patents were deposited during 2004

The Technology Programme mainly involves staff from the Frascati laboratories of the Fusion Technical and Scientific Unit and from the Brasimone laboratories of the Advanced Physics Technologies Unit. Other ENEA units also provide valuable contributions to the programme. ENEA is heavily engaged in component development/testing and in design and safety activities for the European Fusion Technology Programme. Although the work documented in the following covers a large range of topics that differ considerably because they concern the development of extremely complex systems, the high level of integration and coordination ensures the capability to cover the fusion system as a whole. In 2004 the most significant testing activities concerned the ITER primary beryllium-coated first wall. In the field of high-heat-flux components, an important achievement was the qualification of the process for depositing a copper liner on carbon fibre composite (CFC) hollow tiles. This new process, pre-brazed casting (PBC), allows the hot radial pressing (HRP) joining procedure to be used also for CFC-based armour monoblock divertor components. The PBC and HRP processes are candidates for the construction of the ITER divertor. In the materials field an important milestone was the commissioning of a new facility for chemical vapour infiltration/deposition, used for optimising silicon carbide composite (SiCf/SiC) components. Eight patents were deposited during 2004

    Mitra, Bivas

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

    Energy Technology Data Exchange (ETDEWEB)

    1992-03-01

    The Ceramic Technology Project was developed by the USDOE Office of Transportation Systems (OTS) in Conservation and Renewable Energy. This project, part of the OTS's Materials Development Program, was developed to meet the ceramic technology requirements of the OTS's automotive technology programs. Significant accomplishments in fabricating ceramic components for the USDOE and NASA advanced heat engine programs have provided evidence that the operation of ceramic parts in high-temperature engine environments is feasible. These programs have also demonstrated that additional research is needed in materials and processing development, design methodology, and data base and life prediction before industry will have a sufficient technology base from which to produce reliable cost-effective ceramic engine components commercially. A five-year project plan was developed with extensive input from private industry. In July 1990 the original plan was updated through the estimated completion of development in 1993. The objective is to develop the industrial technology base required for reliable ceramics for application in advanced automotive heat engines. The project approach includes determining the mechanisms controlling reliability, improving processes for fabricating existing ceramics, developing new materials with increased reliability, and testing these materials in simulated engine environments to confirm reliability. Although this is a generic materials project, the focus is on the structural ceramics for advanced gas turbine and diesel engines, ceramic bearings and attachments, and ceramic coatings for thermal barrier and wear applications in these engines. To facilitate the rapid transfer of this technology to US industry, the major portion of the work is being done in the ceramic industry, with technological support from government laboratories, other industrial laboratories, and universities.

  2. Technology Roadmapping for Waste Management

    International Nuclear Information System (INIS)

    Bray, O.

    2003-01-01

    Technology roadmapping can be an effective strategic technology planning tool. This paper describes a process for customizing a generic technology roadmapping process. Starting with a generic process reduces the learning curve and speeds up the roadmap development. Similarly, starting with a generic domain model provides leverage across multiple applications or situations within the domain. A process that combines these two approaches facilitates identifying technology gaps and determining common core technologies that can be reused for multiple applications or situations within the domain. This paper describes both of these processes and how they can be integrated. A core team and a number of technology working groups develop the technology roadmap, which includes critical system requirements and targets, technology areas and metrics for each area, and identifies and evaluates possible technology alternatives to recommend the most appropriate ones to pursue. A generalized waste management model, generated by considering multiple situations or applications in terms of a generic waste management model, provides the domain requirements for the technology roadmapping process. Finally, the paper discusses lessons learns from a number of roadmapping projects

    Full Text Available The objective of this study is to analyze the educational practices of using Blackboard in blended learning environments with students of higher education to understand the relationship between technological appropriation and standards of educational technology. To achieve that goal, the following research question was raised: ¿To what extent are the standards of education technology with the appropriation of technology in blended learning environments in higher educa­tion related? The contextual framework of this work includes the following topics: the institution, teaching, teachers and students. The design methodology that was used is of a correlation type. Correlations were carried out to determine the frequency and level in the technological standards as well as the appropriation of technology. In the comparison of the results obtained by the students, the teachers and the platform; we found that students in the school study showed a high degree of technology ownership and this was the same for the performance shown on the technological standards. It was established that teachers play a key role in developing the techno­logical appropriation of students and performance in technology standards.

    Wearable technology projects, to be useful, in the future, must be seamlessly integrated with the Flight Deck of the Future (F.F). The lab contains mockups of space vehicle cockpits, habitat living quarters, and workstations equipped with novel user interfaces. The Flight Deck of the Future is one element of the Integrated Power, Avionics, and Software (IPAS) facility, which, to a large extent, manages the F.F network and data systems. To date, integration with the Flight Deck of the Future has been limited by a lack of tools and understanding of the Flight Deck of the Future data handling systems. To remedy this problem it will be necessary to learn how data is managed in the Flight Deck of the Future and to develop tools or interfaces that enable easy integration of WEAR Lab and EV3 products into the Flight Deck of the Future mockups. This capability is critical to future prototype integration, evaluation, and demonstration. This will provide the ability for WEAR Lab products, EV3 human interface prototypes, and technologies from other JSC organizations to be evaluated and tested while in the Flight Deck of the Future. All WEAR Lab products must be integrated with the interface that will connect them to the Flight Deck of the Future. The WEAR Lab products will primarily be programmed in Arduino. Arduino will be used for the development of wearable controls and a tactile communication garment. Arduino will also be used in creating wearable methane detection and warning system.

    Full Text Available We are facing radical changes in our ways of living in the nearest future. Not necessarily of our own choice, but because tchnological development is moving so fast, that it will have still greater impact on many aspects of our lives. We have seen the beginnings of that change within the latest 35 years or so, but according to newest research that change will speed up immensely in the nearest years to come. The impact of that change or these changes will affect our working life immensely as a consequence of automation. How these changes are brought about and which are their consequences in a broad sense is being attempted to be understood and guessed by researchers. No one knows for sure, but specific patterns are visible. This paper will not try to guess, what will come, but will rather try to understand the deepest ”nature” of technology in order to understand the driving factors in this development: the genesis of technology in a broad sense in order to contibute to the understanding of the basis for the expected development.

    Research results of hard photon technology have been summarized as a part of novel technology development highly utilizing the quantum nature of photon. Hard photon technology refers to photon beam technologies which use photon in the 0.1 to 200 nm wavelength region. Hard photon has not been used in industry due to the lack of suitable photon sources and optical devices. However, hard photon in this wavelength region is expected to bring about innovations in such areas as ultrafine processing and material synthesis due to its atom selective reaction, inner shell excitation reaction, and spatially high resolution. Then, technological themes and possibility have been surveyed. Although there are principle proposes and their verification of individual technologies for the technologies of hard photon generation, regulation and utilization, they are still far from the practical applications. For the photon source technology, the laser diode pumped driver laser technology, laser plasma photon source technology, synchrotron radiation photon source technology, and vacuum ultraviolet photon source technology are presented. For the optical device technology, the multi-layer film technology for beam mirrors and the non-spherical lens processing technology are introduced. Also are described the reduction lithography technology, hard photon excitation process, and methods of analysis and measurement. 430 refs., 165 figs., 23 tabs.

    Vein visualization technology (VVT) devices use near-infrared light to assist location of peripheral veins. The current study investigated the impact of VVT on donor experience and collection success for young blood donors at the Australian Red Cross Blood Service. The study in donors aged 18 to 30 years used a two intervention to one control randomized trial design with 285 new and 587 returning donors recruited at two sites. Donors reported presyncopal symptoms, phlebotomy pain, anxiety and intentions to redonate along with other measures. Participating phlebotomists rated usefulness of the technology. Flow rates, collection volumes and other donation information were taken from routine data. No significant differences were found between control and intervention groups on presyncopal symptoms, phlebotomy pain, anxiety, intentions to redonate, flow rates, collection volumes or vasovagal reactions (all P's > 0·05). Phlebotomist ratings of VVT were significantly more positive when they had less than 5 years of experience (P < 0·01) or when the vein was not visible to the naked eye (P < 0·01). Results suggest that VVT does not improve the donation experience for younger blood donors. Staff reports indicate that VVT may have some utility for assisting with difficult phlebotomies. © 2016 International Society of Blood Transfusion.

    2013-01-01

    Waste incineration is the art of completely combusting waste, while maintaining or reducing emission levels below current emission standards. Where possible, objectives include the recovering of energy as well as the  combustion residues.  Successful waste incineration makes it possible to achieve a deep reduction in waste volume, obtain a compact and sterile residue, and eliminate a wide array of pollutants. This book places waste incineration within the wider context of waste management, and demonstrates that, in contrast to landfills and composting, waste incineration can eliminate objectionable and hazardous properties such as flammability and toxicity, result in a significant reduction in volume, and destroy gaseous and liquid waste streams leaving little or no residues beyond those linked to flue gas neutralization and treatment. Moreover, waste incineration sterilizes and destroys putrescible matter, and produces usable heat.  Incineration Technologies first appeared as a peer-reviewed contribution ...

    Since 2006 NASA has been formulating robotic missions to the lunar surface through programs and projects like the Robotic Lunar Exploration Program, Lunar Precursor Robotic Program, and International Lunar Network. All of these were led by NASA Marshall Space Flight Center (MSFC). Due to funding shortfalls, the lunar missions associated with these efforts, the designs, were not completed. From 2010 to 2013, the Robotic Lunar Lander Development Activity was funded by the Science Mission Directorate (SMD) to develop technologies that would enable and enhance robotic lunar surface missions at lower costs. In 2013, a requirements-driven, low-cost robotic lunar lander concept was developed for the Resource Prospector Mission. Beginning in 2014, The Advanced Exploration Systems funded the lander team and established the MSFC, Johnson Space Center, Applied Physics Laboratory, and the Jet Propulsion Laboratory team with MSFC leading the project. The lander concept to place a 300-kg rover on the lunar surface has been described in the New Technology Report Case Number MFS-33238-1. A low-cost lander concept for placing a robotic payload on the lunar surface is shown in figures 1 and 2. The NASA lander team has developed several lander concepts using common hardware and software to allow the lander to be configured for a specific mission need. In addition, the team began to transition lander expertise to United States (U.S.) industry to encourage the commercialization of space, specifically the lunar surface. The Lunar Cargo Transportation and Landing by Soft Touchdown (CATALYST) initiative was started and the NASA lander team listed above is partnering with three competitively selected U.S. companies (Astrobotic, Masten Space Systems, and Moon Express) to develop, test, and operate their lunar landers.

    Powder technology is experiencing nowadays a great development and has broad application in different fields: nuclear energy, medicine, new energy sources, industrial and home artifacts, etc. Ceramic materials are of daily use as tableware and also in the building industry (bricks, tiles, etc.). However, in machine construction its utilization is not so common. The same happens with metals: powder metallurgy is employed less than traditional metal forming techniques. Both cases deal with powder technology and the forming techniques as far as the final consolidation through sintering processes are very similar. There are many different methods and techniques in the forming stage: cold-pressing, slip casting, injection molding, extrusion molding, isostatic pressing, hot-pressing (which involves also the final consolidation step), etc. This variety allows to obtain almost any desired form no matter how complex it could be. Some applications are very specific as in the case of UO 2 pellets (used as nuclear fuels) but with the same technique and other materials, it is possible to manufacture a great number of different products. This work shows the characteristics and behaviour of two magnetic ceramic materials (ferrites) fabricated in the laboratory of the Applied Research Division of the Bariloche Atomic Center for different purposes. Other materials and products made with the same method are also mentioned. Likewise, densities and shrinkage obtained by different methods of forming (cold-pressing, injection molding, slip casting and extrusion molding) using high-purity alumina (99.5% Al 2 O 3 ). Finally, different applications of such methods are given. (Author) [es

    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.

    The recovery of the Three Mile Island Unit 2 facilities has transformed decontamination from traditional ''mop-and-bucket'' cleaning into an advanced technology. The decontamination of the reactor building and auxiliary and fuel handling building required the development of new methodologies, adaptation of equipment from other fields, and the development of new equipment to meet the projects goals. Experience at TMI-2 has resulted in the development of techniques for; radiological characterization with wide angle detectors and autoradiograhic techniques for the determination of sources and depth of contamination penetration, coatings and base surface removal with ultra-high-pressure water dissolution chemicals and mechanical scabblers (paint-chipping devices), and surface decontamination with high-pressure steam vacuum extraction. This paper presents an overview of the development of decontamination technology and its impact on the TMI-2 program. The benefits of expanding the TMI-2 experience to general use in the nuclear industry are discussed

    2014-02-27

    A novel solid-phase microextraction(SPME) fiber was prepared using sol-gel technology with ethoxylated nonylphenol as a fiber coating material. The fiber was employed to develop a headspace SPME-GC-MS method suitable for quantification of 13 polycyclic aromatic hydrocarbons (PAHs) in water samples. Surface characteristics of the fibers were inspected by energy dispersive X-ray (EDX) spectroscopy as well as by scanning electron microscopy (SEM). The SEM measurements showed the presence of highly porous nano-sized particles in the coating. Important parameters affecting the extraction efficiency such as extraction temperature and time, desorption conditions as well as ionic strength have been evaluated and optimized. In the next step, the validation of the new method have been performed, finding it to be specific in the trace analysis of PAHs, with the limit of detection (LOD) ranging from 0.01 to 0.5 μg L(-1) and the linear range from the respective LOD to 200 μg L(-1) with RSD amounting to less than 8%. The thermal stability of the fibers was investigated as well and they were found to be durable at 280°C for 345 min. Furthermore, the proposed method was successfully applied for quantification of PAHs in real water samples. Copyright © 2014 Elsevier B.V. All rights reserved.

    Ritchie, Lisa M.

    2004-01-01

    Throughout the summer of 2004, I am working on a number of different projects. While located in the Space Power and Propulsion Test Engineering branch, my main area of study is flywheel technology. I have been exposed to flywheels, their components, and their uses in today's society. I have been able to experience numerous flywheels here in the flywheel lab at NASA Glenn. My first main project was to explore the attributes and physical characteristics of a flywheel. Our branch was constructing a flywheel demonstration to be presented at the public open house taking place in June. Our Flywheel Interactive Demo, or FIDO, represents a real life multi-flywheel system here at NASA. I was given the opportunity to learn about how these flywheels store energy and are able to position a satellite. With all of this new knowledge, I was able to create the posters that explained how our demonstration worked. I also composed a step-by-step process made up of four experiments that any visitor could follow and perform on FIDO. By stepping through these experiments, the individual learns how a flywheel works. They not only read the explanation of what is happening, but they are also able to see it happen. Creating these two posters not only taught me, but also helped teach the general public during the open house, how flywheel technology is a very important part of our future. Through my research, I have learned that flywheels are able to store massive amounts of energy. They can be described as an electro-mechanical battery that stores kinetic energy while rotating. The faster it rotates, the more energy it stores. Their lifetime is about triple that of an ordinary battery. Flywheels also have the ability to combine energy storage with attitude control all in a single system. Attitude control is the ability to position a satellite as required. FIDO helps us to understand the rotational force (torque) that is applied upon a turn-table or satellite during wheel acceleration

  18. Nuclear fuel technology - Determination of milligram amounts of plutonium in nitric acid solutions - Potentiometric titration with potassium dichromate after oxidation by Ce(IV) and reduction by Fe(II)

    International Nuclear Information System (INIS)

    2000-01-01

    This International Standard describes a precise and accurate analytical method for determining 1 mg to 5 mg of plutonium per millilitre in nitric acid solutions. The method is very selective for plutonium. It is suitable for the direct determination of plutonium in materials ranging from pure product solutions, to solutions of mixed nuclear materials with a uranium/plutonium ratio up to 20:1. However, potential application to the assay of plutonium in solutions of irradiated nuclear fuels and solutions of mixed nuclear materials with uranium/plutonium ratios of 20:1 to 33:1 has not yet been documented. The method recommends that the aliquot be weighed and that the titration burettes be calibrated gravimetrically in order to obtain adequate precision and accuracy. This does not preclude using any alternative technique which can be shown to give an equivalent accuracy. As the reproducibility of the reaction conditions is important to maintain good performance, extensive automatization of the procedure is beneficial

    2007-09-01

    This technology development plan is designed to provide a clear understanding of the research and development direction necessary for the qualification of nuclear grade graphite for use within the Next Generation Nuclear Plant (NGNP) reactor. The NGNP will be a helium gas cooled Very High Temperature Reactor (VHTR) with a large graphite core. Graphite physically contains the fuel and comprises the majority of the core volume. Considerable effort will be required to ensure that the graphite performance is not compromised during operation. Based upon the perceived requirements the major data needs are outlined and justified from the perspective of reactor design, reatcor performance, or the reactor safety case. The path forward for technology development can then be easily determined for each data need. How the data will be obtained and the inter-relationships between the experimental and modeling activities will define the technology development for graphite R&D. Finally, the variables affecting this R&D program are discussed from a general perspective. Factors that can significantly affect the R&D program such as funding, schedules, available resources, multiple reactor designs, and graphite acquisition are analyzed.

  20. Green technology meets ecotoxicology

    Directory of Open Access Journals (Sweden)

    Kristina Radošević

    2016-01-01

    Full Text Available By applying concept and principles of green chemistry into different technological processes, green technologies are developed. The environmental and economic benefits of “green” approach is achieved through several directions, such as the use of renewable raw materials, creation of economic efficiency, the use of alternative reaction conditions, as well as the application of non-conventional solvents. From the point view of green chemistry, alternative solvents, in order to be a “green“ substitution to hazardous organic solvents, should be: non-volatile, non-flammable, stabile, synthesized by an environmentally friendly procedure, nontoxic and biodegradable. The toxic impact of all newly synthesized chemicals, such as alternative solvents, could be determined by methods and techniques of ecotoxicology. Ecotoxicology, an interdisciplinary scientific field, can serve as a way of monitoring the greenness of the processes. In vivo and in vitro experiments are used to study the effects of chemicals on different levels of organizations, from molecules to communities and ecosystem. The usage of in vitro methods is encouraged by a scientific community and regulatory agencies as an alternative to in vivo studies in order to reduce the number of laboratory animals used in the toxicological studies. Therefore, in this paper we gave a brief overview on the usage of animal cell cultures within the field of green chemistry and technology.

    This book is the first in a set of forthcoming books focussed on state-of-the-art development in the VLSI Signal Processing area. It is a response to the tremendous research activities taking place in that field. These activities have been driven by two factors: the dramatic increase in demand for high speed signal processing, especially in consumer elec­ tronics, and the evolving microelectronic technologies. The available technology has always been one of the main factors in determining al­ gorithms, architectures, and design strategies to be followed. With every new technology, signal processing systems go through many changes in concepts, design methods, and implementation. The goal of this book is to introduce the reader to the main features of VLSI Signal Processing and the ongoing developments in this area. The focus of this book is on: • Current developments in Digital Signal Processing (DSP) pro­ cessors and architectures - several examples and case studies of existing DSP chips are discussed in...

    Industrial-scale systems more and more come to be the determining form of scientific-technological progress, and contribute, together with the system of standards and values, to social integration in technological civilization. Sociology has discovered industrial-scale systems rather late as an independent research subject. In view of nuclear energy systems; newly arising, worldwide information systems, or even the increasing cross-linking of transport systems, men became aware of the fact that technology in addition to industry, politics, economy or science had developed into an independent social sphere which, to a growing extent, was structured by large-scale systems. Nowadays it is not determinism, the inescapable superstructure or the one-dimensionality of technology that play a role, but questions of controlling, complexity, unpredictability and contingency, and of the uncontrollable consequences of industrial- scale technologies stir up emotions. Since industrial-scale systems have become a determining factor of social development, the questions of their social and environmental compatibility, and how to integrate them into a democratic order, become more and more urgent. The papers compiled in the Annual Report give some hints to this effect. The papers on theoretical concepts are individually retrievable from the database. (orig./HSCH) [de

    A Personal Health Record (PHR) is an online application that allows patients to access, manage, and share their health data. PHRs not only enhance shared decision making with healthcare providers, but also enable remote monitoring and at-home-collection of detailed data. The benefits of PHRs can be maximized in insulin dose adjustment for patients starting or intensifying insulin regimens, as frequent self-monitoring of glucose, self-adjustment of insulin dose, and precise at-home data collection during the visit-to-visit period are important for glycemic control. The aim of this study is to examine the efficacy and safety of insulin dose adjustment based on a smartphone PHR application in patients with diabetes mellitus (DM) and to confirm the validity and stability of an information and communication technology (ICT)-based centralized clinical trial monitoring system. This is a 24-week, open-label, randomized, multi-center trial. There are three follow-up measures: baseline, post-intervention at week 12, and at week 24. Subjects diagnosed with type 1 DM, type 2 DM, and/or post-transplant DM who initiate basal insulin or intensify their insulin regimen to a basal-bolus regimen are included. After education on insulin dose titration and prevention for hypoglycemia and a 1-week acclimation period, subjects are randomized in a 1:1 ratio to either an ICT-based intervention group or a conventional intervention group. Subjects in the conventional intervention group will save and send their health information to the server via a PHR application, whereas those in ICT-based intervention group will receive additional algorithm-based feedback messages. The health information includes level of blood glucose, insulin dose, details on hypoglycemia, food diary, and step count. The primary outcome will be the proportion of patients who reach an optimal insulin dose within 12 weeks of study enrollment, without severe hypoglycemia or unscheduled clinic visits. This clinical trial

    Environmental Management Operations (EMO) is conducting an Innovative Technology Demonstration Program for Tinker Air Force Base (TAFB). Several innovative technologies are being demonstrated to address specific problems associated with remediating two contaminated test sites at the base. Cone penetrometer testing (CPT) is a form of testing that can rapidly characterize a site. This technology was selected to evaluate its applicability in the tight clay soils and consolidated sandstone sediments found at TAFB. Directionally drilled horizontal wells was selected as a method that may be effective in accessing contamination beneath Building 3001 without disrupting the mission of the building, and in enhancing the extraction of contamination both in ground water and in soil. A soil gas extraction (SGE) demonstration, also known as soil vapor extraction, will evaluate the effectiveness of SGE in remediating fuels and TCE contamination contained in the tight clay soil formations surrounding the abandoned underground fuel storage vault located at the SW Tanks Site. In situ sensors have recently received much acclaim as a technology that can be effective in remediating hazardous waste sites. Sensors can be useful for determining real-time, in situ contaminant concentrations during the remediation process for performance monitoring and in providing feedback for controlling the remediation process. Following the SGE demonstration, the SGE system and SW Tanks test site will be modified to demonstrate bioremediation as an effective means of degrading the remaining contaminants in situ. The bioremediation demonstration will evaluate a bioventing process in which the naturally occurring consortium of soil bacteria will be stimulated to aerobically degrade soil contaminants, including fuel and TCE, in situ

    Currently, several innovative technologies are being demonstrated at Tinker Air Force Base (TAFB) to address specific problems associated with remediating two contaminated test sites at the base. Cone penetrometer testing (CPT) is a form of testing that can rapidly characterize a site. This technology was selected to evaluate its applicability in the tight clay soils and consolidated sandstone sediments found at TAFB. Directionally drilled horizontal wells have been successfully installed at the US Department of Energy's (DOE) Savannah River Site to test new methods of in situ remediation of soils and ground water. This emerging technology was selected as a method that may be effective in accessing contamination beneath Building 3001 without disrupting the mission of the building, and in enhancing the extraction of contamination both in ground water and in soil. A soil gas extraction (SGE) demonstration, also known as soil vapor extraction, will evaluate the effectiveness of SGE in remediating fuels and TCE contamination contained in the tight clay soil formations surrounding the abandoned underground fuel storage vault located at the SW Tanks Site. In situ sensors have recently received much acclaim as a technology that can be effective in remediating hazardous waste sites. Sensors can be useful for determining real-time, in situ contaminant concentrations during the remediation process for performance monitoring and in providing feedback for controlling the remediation process. A demonstration of two in situ sensor systems capable of providing real-time data on contamination levels will be conducted and evaluated concurrently with the SGE demonstration activities. Following the SGE demonstration, the SGE system and SW Tanks test site will be modified to demonstrate bioremediation as an effective means of degrading the remaining contaminants in situ

    antennas closer than 20 cm. Regarding UHF (868 MHz) and microwave (2,45 GHz) reader devices it was demonstrated that exposure above the basic restriction is not to be expected as long as a minimum distance to the antennas of 10 cm - 20 cm is maintained. Concerning exposure from currently widest deployed Electronic Article Surveillance (EAS) technology also differences between technologies become obvious. While the numerous measurements and computations carried out did not give indications that radio frequency (RF)-EAS devices (operating frequency range typically 7,5-8,9 MHz) cause exposure above the basic restrictions defined in ICNIRP 1998, it could be demonstrated that for acoustomagnetic (AM)-EAS systems (operating frequency 58 kHz) exposure above the ICNIRP 1998 basic restrictions is possible, when approaching the antenna very closely, i.e., at unusual short distances of less than a few centimeters between the trunk and/or the head and the antenna. With respect to the assessment of the exposure caused by the RFID- and EAS devices with operating frequencies less than 10 MHz (particularly close to and below 100 kHz), it must be noted that the assessment summarized above was carried out based on the ICNIRP guidelines published in 1998, i.e., that the basic restriction in terms of current density was applied only to central nervous (CNS) tissue. It must be expected that the application of the new assessment concept recently published by ICNIRP 2010, which is based of induced electric field strength inside the tissue and which provides now also limits for all body tissues and not only for CNS tissue, may lead to significant different assessment results and conclusions for the mentioned device categories. Regarding possible electromagnetic interference with cardiac pacemakers, again RFID- and EAS-devices with working frequencies 58 kHz and 120 kHz and large (e.g., floor standing) antennas showed up to have the highest potential for interference compared to the other

    The paper discusses the objectives of a hydrogen energy systems technology study directed toward determining future demand for hydrogen based on current trends and anticipated new uses and identifying the critical research and technology advancements required to meet this need with allowance for raw material limitations, economics, and environmental effects. Attention is focused on historic production and use of hydrogen, scenarios used as a basis for projections, projections of energy sources and uses, supply options, and technology requirements and needs. The study found more than a billion dollar annual usage of hydrogen, dominated by chemical-industry needs, supplied mostly from natural gas and petroleum feedstocks. Evaluation of the progress in developing nuclear fusion and solar energy sources relative to hydrogen production will be necessary to direct the pace and character of research and technology work in the advanced water-splitting areas.

    This study deals with the question whether increasing social conflicts around technology in general as well as specific technological projects can be reasonably interpreted as evidence for a substantive politicization of production in advanced capitalist democracies with historically new social problems and cleavages. Therefore, the socio-economic conditions and determinants of technological protest, the typical features of technological controversies, and the characteristics of the German protest development are described. The available rsearch results provide some indications for the above hypothesis but do not allow any stringent conclusions yet for reasons which relate conclusively to the pattern of protest development hitherto observable, and to still existing deficits of social science research.

After a brief review of the methods that have been used to measure the phantoms for a contextual backdrop to our approach, this paper reports on the establishment of a standardized double-integrating-sphere platform to measure absorption and reduced scattering coefficients of tissue-mimicking biomedical phantoms. The platform implements a user-friendly graphical user interface in which variations of experimental configurations and model-based analysis are implemented to compute the coefficients based on a modified inverse adding-doubling algorithm allowing a complete uncertainty evaluation. Repeatability and validation of the measurement results of solid phantoms are demonstrated for three samples of different thicknesses, d=5.08 mm, 7.09 mm, and 9.92 mm, with an absolute error estimate of 4.0% to 5.0% for the absorption coefficient and 11% to 12% for the reduced scattering coefficient (k=2). The results are in accordance with those provided by the manufacturer. Measurements with different polarization angles of the incident light are also presented, and the resulting optical properties were determined to be equivalent within the estimated uncertainties.

    A selective analytical method for the simultaneous determination of 20 triazole fungicides and plant growth regulators in cucumber samples was developed using solid-phase extraction with specific molecularly imprinted polymers (MIPs) as adsorbents. The MIPs were successfully prepared by precipitation polymerization using triadimefon as the template molecule, methacrylic acid as the functional monomer, trimethylolpropane trimethacrylate as the crosslinker, and acetonitrile as the porogen. The performance and recognition mechanism for both the MIPs and non-molecularly imprinted polymers were evaluated using adsorption isotherms and adsorption kinetics. Liquid chromatography-tandem quadrupole mass spectrometry was used to identify and quantify the target analytes. The solid-phase extraction using the MIPs was rapid, convenient, and efficient for extraction and enrichment of the 20 triazole pesticides from cucumber samples. The recoveries obtained at three concentration levels (1, 2, and 10μgL -1 ) ranged from 82.3% to 117.6% with relative standard deviations of less than 11.8% (n=5) for all analytes. The limits of detection for the 20 triazole pesticides were all less than 0.4μgL -1 , and were sufficient to meet international standards. Copyright © 2017 Elsevier B.V. All rights reserved.

    2015-01-01

    Full Text Available The paper aims at discussing techniques for administering one implementation issue that often arises in the application of particle filters: sample impoverishment. Dealing with such problem can significantly improve the performance of particle filters and can make the difference between success and failure. Sample impoverishment occurs because of the reduction in the number of truly distinct sample values. A simple solution can be to increase the number of particles, which can quickly lead to unreasonable computational demands, which only delays the inevitable sample impoverishment. There are more intelligent ways of dealing with this problem, such as roughening and prior editing, procedures to be discussed herein. The nonlinear particle filter is based on the bootstrap filter for implementing recursive Bayesian filters. The application consists of determining the orbit of an artificial satellite using real data from the GPS receivers. The standard differential equations describing the orbital motion and the GPS measurements equations are adapted for the nonlinear particle filter, so that the bootstrap algorithm is also used for estimating the orbital state. The evaluation will be done through convergence speed and computational implementation complexity, comparing the bootstrap algorithm results obtained for each technique that deals with sample impoverishment.

    Lysophosphatidic acid (LPA) and sphingosine-1-phosphate (S1P) are growth factor-like lipids having a phosphate group. The concentrations of these mediator lipids in blood are considered to be potential biomarkers for early detection of cancer or vascular diseases. Here, we report a method for simultaneous determination of LPA and S1P using Phos-tag, a zinc complex that specifically binds to a phosphate-monoester group. Although both LPA and S1P are hydrophilic compounds, we found that they acquire hydrophobic properties when they form complexes with Phos-tag. Based on this finding, we developed a method for the enrichment of LPA and S1P from biological samples. The first partition in a two-phase solvent system consisting of chloroform/methanol/water (1:1:0.9, v/v/v) is conducted for the removal of lipids. LPA and S1P are specifically extracted as Phos-tag complexes at the second partition by adding Phos-tag. The Phos-tag complexes of LPA and S1P are detectable by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS) and quantifiable based on the relative intensities of ions using 17:0 LPA and C17 S1P as internal standards. The protocol was validated by analyses of these mediator lipids in calf serum, a rat brain and a lung. The clean-up protocol is rapid, requires neither thin-layer chromatography (TLC) nor liquid chromatography (LC), and is applicable to both blood and solid tissue samples. We believe that our protocol will be useful for a routine analysis of LPA and S1P in many clinical samples. 2010 John Wiley & Sons, Ltd.

  10. Plasmid transfection in bovine cells: Optimization using a realtime monitoring of green fluorescent protein and effect on gene reporter assay.

    Science.gov (United States)

    Osorio, Johan S; Bionaz, Massimo

    2017-08-30

    Gene reporter technology (GRT) has opened several new avenues for monitoring biological events including the activation of transcription factors, which are central to the study of nutrigenomics. However, this technology relies heavily on the insertion of foreign plasmid DNA into the nuclei of cells (i.e., transfection), which can be very challenging and highly variable among cell types. The objective of this study was to investigate the optimal conditions to generate reliable GRT assay data on bovine immortalized cell lines, Madin Darby Bovine Kidney (MDBK) and bovine mammary epithelial alveolar (MACT) cells. Results are reported for two experiments. In Experiment 1, using 96 well-plate and a robotic inverted fluorescent microscope, we compared transfection efficiency among commercially available transfection reagents (TR) Lipofectamine® 3000 (Lipo3), Lipofectamine® LTX (LipoLTX), and TransIT-X2® (TransX2), three doses of TR (i.e., 0.15, 0.3, and 0.4μL/well), and three doses of Green Fluorescent Protein plasmid DNA (i.e., 10, 25, and 50ng/well). Transfection efficiency and mortality rate were analyzed using CellProfiler software. Transfection efficiency increased until the end of the experiment (20h post-transfection) at which point MACT had greater transfection than MDBK cells (16.3% vs. 2.2%). It is unclear the reason for the low transfection in MDBK cells. Maximal transfection efficiency was obtained with 0.3μL/well of LipoLTX plus 25ng/well of plasmid DNA (ca. 29.5±1.9%) and 0.15μL/well of LipoLTX plus 25ng/well of plasmid DNA (ca. 4.0±0.4%) for MACT and MDBK cells, respectively. The higher amount of TR and DNA was generally associated with higher cell mortality. Using high, medium, and low transfection efficiency conditions determined in Experiment 1, we performed a GRT assay for peroxisome proliferator-activated response element (PPRE) luciferase in MACT and MDBK cells treated with 10nM or 100nM of synthetic Peroxisome Proliferator-activated Receptor

    The nuclear industry has been slow to incorporate digital sensor technology into nuclear plant designs due to concerns with digital qualification issues. However, the benefits of digital sensor technology for nuclear plant instrumentation are substantial in terms of accuracy and reliability. This paper, which refers to a final report issued in 2013, demonstrates these benefits in direct comparisons of digital and analog sensor applications. Improved accuracy results from the superior operating characteristics of digital sensors. These include improvements in sensor accuracy and drift and other related parameters which reduce total loop uncertainty and thereby increase safety and operating margins. An example instrument loop uncertainty calculation for a pressure sensor application is presented to illustrate these improvements. This is a side-by-side comparison of the instrument loop uncertainty for both an analog and a digital sensor in the same pressure measurement application. Similarly, improved sensor reliability is illustrated with a sample calculation for determining the probability of failure on demand, an industry standard reliability measure. This looks at equivalent analog and digital temperature sensors to draw the comparison. The results confirm substantial reliability improvement with the digital sensor, due in large part to ability to continuously monitor the health of a digital sensor such that problems can be immediately identified and corrected. This greatly reduces the likelihood of a latent failure condition of the sensor at the time of a design basis event. Notwithstanding the benefits of digital sensors, there are certain qualification issues that are inherent with digital technology and these are described in the report. One major qualification impediment for digital sensor implementation is software common cause failure (SCCF).

  2. Fundamentals of technology roadmapping

    Energy Technology Data Exchange (ETDEWEB)

    Garcia, M.L.; Bray, O.H.

    1997-04-01

    Technology planning is important for many reasons. Globally, companies are facing many competitive problems. Technology roadmapping, a form of technology planning can help deal with this increasingly competitive environment. While it has been used by some companies and industries, the focus has always been on the technology roadmap as a product, not on the process. This report focuses on formalizing the process so that it can be more broadly and easily used. As a DOE national security laboratory with R&D as a major product, Sandia must do effective technology planning to identify and develop the technologies required to meet its national security mission. Once identified, technology enhancements or new technologies may be developed internally or collaboratively with external partners. For either approach, technology roadmapping, as described in this report, is an effective tool for technology planning and coordination, which fits within a broader set of planning activities. This report, the second in a series on technology roadmapping, develops and documents this technology roadmapping process, which can be used by Sandia, other national labs, universities, and industry. The main benefit of technology roadmapping is that it provides information to make better technology investment decisions by identifying critical technologies and technology gaps and identifying ways to leverage R&D investments. It can also be used as a marketing tool. Technology roadmapping is critical when the technology investment decision is not straight forward. This occurs when it is not clear which alternative to pursue, how quickly the technology is needed, or when there is a need to coordinate the development of multiple technologies. The technology roadmapping process consists of three phases - preliminary activity, development of the technology roadmap, and follow-up activity.

  3. Innovations in Lithotripsy Technology

    2007-04-01

    The introduction of shock wave lithotripsy (SWL) in the early 1980's revolutionized the surgical management for kidney stone disease. Since then, although numerous 2nd- and 3rd-generation lithotripters have been developed using various means for shock wave generation, focusing, patient coupling and stone localization, the technical improvements in these devices were largely made based on practical concerns for user convenience and multifunctionality of the system rather than a clear understanding of the working principles of SWL. In this paper, the fundamental mechanisms of stone comminution and tissue injury in SWL revealed by basic studies in the past two decades are first reviewed. This is followed by a summary of the innovations in SWL technology developed in recent years that have been demonstrated to provide improved stone comminution with concomitantly reduced tissue injury both in vitro using phantom systems and in vivo in animal models. Furthermore, the role of treatment strategy in determining the overall outcome of clinical lithotripsy is emphasized, and future prospects for lithotripsy research and technological innovations are discussed.

  19. Is light water reactor technology sustainable?

    International Nuclear Information System (INIS)

    Rothwell, G.; Van der Zwaan, B.

    2001-01-01

    This paper proposes criteria for determining ''intermediate sustainability'' over a 500-year horizon. We apply these criteria to Light Water Reactor (LWR) technology and the LWR industry. We conclude that LWR technology does not violate intermediate sustainability criteria for (1) environmental externalities, (2) worker and public health and safety, or (3) accidental radioactive release. However, it does not meet criteria to (1) efficiently use depleted uranium and (2) avoid uranium enrichment technologies that can lead to nuclear weapons proliferation. Finally, current and future global demand for LWR technology might be below the minimum needed to sustain the current global LWR industry. (author)

  3. Technology transfer equipment qualification methodology for shelf life determination

    International Nuclear Information System (INIS)

    Anderson, J.W.

    1995-01-01

    Discussions with a number of Nuclear Utilities revealed that equipment qualified for 10 to 40 years in the harsh environment of the plant was being assigned shelf lives of only 5 to 10 years in the benign environment of the warehouse, and then the materials were being trashed. One safety-related equipment supplier was assigning a 10-year qualified life, from date of shipment, with no recognition of the difference in the aging rate in the plant vs. that in the warehouse. Many suppliers assign shelf lives based on product warranty considerations rather than actual product degradation. An EPRI program was initiated to evaluate the methods used to assign shelf lives and to adapt the Arrhenius methodology, used in equipment qualification, to assign technically justifiable shelf lives. Temperature is the main factor controlling shelf life; however, atmospheric pressure, humidity, ultraviolet light, ozone and other atmospheric contaminants were also considered. A list of 70 representative materials was addressed in the program. All of these were found to have shelf lives of 14 years to greater than 60 years, except for 19 items. For 18 of these items, there was no data available except for the manufacturer's recommendation

  7. Passive infrared motion sensing technology

    International Nuclear Information System (INIS)

    Doctor, A.P.

    1994-01-01

    In the last 10 years passive IR based (8--12 microns) motion sensing has matured to become the dominant method of volumetric space protection and surveillance. These systems currently cost less than $25 to produce and yet use traditionally expensive IR optics, filters, sensors and electronic circuitry. This IR application is quite interesting in that the volumes of systems produced and the costs and performance level required prove that there is potential for large scale commercial applications of IR technology. This paper will develop the basis and principles of operation of a staring motion sensor system using a technical approach. A model for the motion of the target is developed and compared to the background. The IR power difference between the target and the background as well as the optical requirements are determined from basic principles and used to determine the performance of the system. Low cost reflective and refractive IR optics and bandpass IR filters are discussed. The pyroelectric IR detector commonly used is fully discussed and characterized. Various schemes for ''false alarms'' have been developed and are also explained. This technology is also used in passive IR based motion sensors for other applications such as lighting control. These applications are also discussed. In addition the paper will discuss new developments in IR surveillance technology such as the use of linear motion sensing arrays. This presentation can be considered a ''primer'' on the art of Passive IR Motion Sensing as applied to Surveillance Technology

  13. Health technology assessment in Greece.

    Science.gov (United States)

    Liaropoulos, L; Kaitelidou, D

    2000-01-01

    In 1983 a health reform aimed to assure universal coverage and equity in the distribution of services in Greece. The reform implied state responsibility for the financing and delivery of services and a reduction of the private sector. The model was a Bismarckian scheme for social insurance. However, healthcare delivery remains fragmented and uncoordinated and the private sector is getting stronger. The dominant payment system is fee-for-service for the private sector and administered prices and salaries for public hospitals and social insurance funds. The many insurers have their own eligibility requirements, validation procedures, etc. Coverage of services by social security funds, probably among the most comprehensive in Europe, is determined more on historical and political grounds than on efficiency or cost-effectiveness. The system is plagued by problems, including geographical inequalities, overcentralization, bureaucratic management, poor incentives in the public sector, open-ended financing, inefficient use of hospital beds, and lack of cost-effectiveness. There are no specific legal provisions for the control of health technology. Technologies are introduced without standards or formal consideration of needs. There are no current efforts to control health technology in Greece. However, health technology assessment (HTA) has gained increasing visibility. In 1997 a law provided for a new government agency responsible for quality control, economic evaluation of health services, and HTA. The hope is that the new law may introduce evaluation and assessment elements into health policy formulation and assure that cost effectiveness, quality, and appropriate use of health technology will receive more attention.

  20. Key factors affecting the deployment of electricity generation technologies in energy technology scenarios

    Energy Technology Data Exchange (ETDEWEB)

    Ruoss, F.; Turton, H.; Hirschberg, S.

    2009-12-15

    This report presents the findings of a survey of key factors affecting the deployment of electricity generation technologies in selected energy scenarios. The assumptions and results of scenarios, and the different models used in their construction, are compared. Particular attention is given to technology assumptions, such as investment cost or capacity factors, and their impact on technology deployment. We conclude that the deployment of available technologies, i.e. their market shares, can only be explained from a holistic perspective, and that there are strong interactions between driving forces and competing technology options within a certain scenario. Already the design of a scenario analysis has important impacts on the deployment of technologies: the choice of the set of available technologies, the modeling approach and the definition of the storylines determine the outcome. Furthermore, the quantification of these storylines into input parameters and cost assumptions drives technology deployment, even though differences across the scenarios in cost assumptions are not observed to account for many of the observed differences in electricity technology deployment. The deployment can only be understood after a consideration of the interplay of technology options and the scale of technology deployment, which is determined by economic growth, end-use efficiency, and electrification. Some input parameters are of particular importance for certain technologies: CO{sub 2} prices, fuel prices and the availability of carbon capture and storage appear to be crucial for the deployment of fossil-fueled power plants; maximum construction rates and safety concerns determine the market share of nuclear power; the availability of suitable sites represents the most important factor for electricity generation from hydro and wind power plants; and technology breakthroughs are needed for solar photovoltaics to become cost-competitive.

  15. Advanced manufacturing: Technology diffusion

    Energy Technology Data Exchange (ETDEWEB)

    Tesar, A.

    1995-12-01

    In this paper we examine how manufacturing technology diffuses rom the developers of technology across national borders to those who do not have the capability or resources to develop advanced technology on their own. None of the wide variety of technology diffusion mechanisms discussed in this paper are new, yet the opportunities to apply these mechanisms are growing. A dramatic increase in technology diffusion occurred over the last decade. The two major trends which probably drive this increase are a worldwide inclination towards ``freer`` markets and diminishing isolation. Technology is most rapidly diffusing from the US In fact, the US is supplying technology for the rest of the world. The value of the technology supplied by the US more than doubled from 1985 to 1992 (see the Introduction for details). History shows us that technology diffusion is inevitable. It is the rates at which technologies diffuse to other countries which can vary considerably. Manufacturers in these countries are increasingly able to absorb technology. Their manufacturing efficiency is expected to progress as technology becomes increasingly available and utilized.
