  9. Art : accessible, renewable technology

    International Nuclear Information System (INIS)

    Middleton, C.D.

    2004-01-01

    This paper focuses on the role of non-governmental organization (NGO) citizen groups in Ontario in the use and production of electricity. NGOs have the potential to act both directly on their own accord, and indirectly by pressuring government and others. Current demand for electricity is divided between industrial, commercial and residential users. Citizens have an important role to play in reducing energy demand. On the supply side, there is a revival of interest in renewable energy based on wind, photovoltaic and local-hydro technologies as a result of the escalating environmental and economic costs of coal and nuclear generation. However, citizen groups have greater interest and enthusiasm than technical expertise, creating a mismatch between technological solutions and human need or use of them. This paper discusses how this mismatch applies to renewable-energy technologies, many of which are not especially user-friendly, or accessible. While alternative technologies are increasingly welcomed by government, industry is developing a large and growing array of technological devices. In between this is the citizen, who, despite keen interest, can be overwhelmed by the complexity of the situation. This paper links the theoretical perspective to the real world with a discussion of the dynamics between people and renewable energy in citizen groups and makes particular reference to one group, Citizens for Renewable Energy, that has been making renewable energy technology more accessible to its members for over a decade

    Boyer, P; Montjean, D; Tourame, P; Gervoise-Boyer, M

    2013-09-01

    Oocyte vitrification has been authorized in France after the modification of French bioethics law in July 2011. This evolution will bring a dramatic change in patients' management since, from 2011, infertile couples, oocyte donation and fertility preservation programs will benefit this technique in France. We have introduced oocyte vitrification in our ART laboratory through a validation of the method using Evidence-Based Medicine model: open system Cryotop, Ethylène-glycol 15% and DMSO 15%. Based on our 1-year experience, oocyte vitrification upgrades our daily practice while also minimizing embryo cryoconservation as recommended by the law. Copyright © 2013 Elsevier Masson SAS.

    Many healthcare organizations are weighing the advantages of investing in a new laboratory information system (LIS) that promises greater accuracy and efficiency against the challenges of replacing the organization's existing LIS system. A recent KLAS survey considers the ROI of replacing an LIS with a next-generation solution, and whether providers are trending toward single-vendor integration or best-of-breed feature sets. Almost 70 percent of the 266 providers interviewed believe there is no "best" LIS.

    The Arctic Energy Technology Development Laboratory was created by the University of Alaska Fairbanks in response to a congressionally mandated funding opportunity through the U.S. Department of Energy (DOE), specifically to encourage research partnerships between the university, the Alaskan energy industry, and the DOE. The enabling legislation permitted research in a broad variety of topics particularly of interest to Alaska, including providing more efficient and economical electrical power generation in rural villages, as well as research in coal, oil, and gas. The contract was managed as a cooperative research agreement, with active project monitoring and management from the DOE. In the eight years of this partnership, approximately 30 projects were funded and completed. These projects, which were selected using an industry panel of Alaskan energy industry engineers and managers, cover a wide range of topics, such as diesel engine efficiency, fuel cells, coal combustion, methane gas hydrates, heavy oil recovery, and water issues associated with ice road construction in the oil fields of the North Slope. Each project was managed as a separate DOE contract, and the final technical report for each completed project is included with this final report. The intent of this process was to address the energy research needs of Alaska and to develop research capability at the university. As such, the intent from the beginning of this process was to encourage development of partnerships and skills that would permit a transition to direct competitive funding opportunities managed from funding sources. This project has succeeded at both the individual project level and at the institutional development level, as many of the researchers at the university are currently submitting proposals to funding agencies, with some success.

  16. Laboratory automation: trajectory, technology, and tactics.

    Science.gov (United States)

    Markin, R S; Whalen, S A

    2000-05-01

    Laboratory automation is in its infancy, following a path parallel to the development of laboratory information systems in the late 1970s and early 1980s. Changes on the horizon in healthcare and clinical laboratory service that affect the delivery of laboratory results include the increasing age of the population in North America, the implementation of the Balanced Budget Act (1997), and the creation of disease management companies. Major technology drivers include outcomes optimization and phenotypically targeted drugs. Constant cost pressures in the clinical laboratory have forced diagnostic manufacturers into less than optimal profitability states. Laboratory automation can be a tool for the improvement of laboratory services and may decrease costs. The key to improvement of laboratory services is implementation of the correct automation technology. The design of this technology should be driven by required functionality. Automation design issues should be centered on the understanding of the laboratory and its relationship to healthcare delivery and the business and operational processes in the clinical laboratory. Automation design philosophy has evolved from a hardware-based approach to a software-based approach. Process control software to support repeat testing, reflex testing, and transportation management, and overall computer-integrated manufacturing approaches to laboratory automation implementation are rapidly expanding areas. It is clear that hardware and software are functionally interdependent and that the interface between the laboratory automation system and the laboratory information system is a key component. The cost-effectiveness of automation solutions suggested by vendors, however, has been difficult to evaluate because the number of automation installations are few and the precision with which operational data have been collected to determine payback is suboptimal. The trend in automation has moved from total laboratory automation to a

  18. Technology transfer in the national laboratories

    Energy Technology Data Exchange (ETDEWEB)

    Yonas, G.

    1991-08-01

    The title of this paper might unfairly provoke readers if it conjures up visions of vast stores of high-tech gadgets in several hundred technology warehouses'' (also known as federal laboratories) around the country, open for browsing by those in search of a bargain. That vision, unfortunately, is a mirage. The term technology transfer'' is not really as accurate as is the term technology team-work,'' a process of sharing ideas and knowledge rather than widgets. In addition, instead of discussing the efforts of more than 700 federal labs in the US, I mean to address only those nine government-owned, contractor-operated multiprogram labs run by the Department of Energy. Nevertheless, the topic of technology team-work opportunities with DOE multiprogram national lab is of significance to those concerned with increasing economic competitiveness and finding technological solutions to a host of national problems. A significant fraction of US R D capabilities rests in the nine DOE multiprogram national laboratories -- and these labs have only just begun to join the other federal laboratories in these efforts due to the passage and recent implementation of the National Competitiveness Technology Transfer Act of 1989.

    1993-09-01

    The Oak Ridge National Laboratory Technology Logic Diagram (TLD) was developed to provide a decision support tool that relates environmental restoration (ER) and waste management (WM) problems at Oak Ridge National Laboratory (ORNL) to potential technologies that can remediate these problems. The TLD identifies the research, development, demonstration testing, and evaluation needed to develop these technologies to a state that allows technology transfer and application to decontamination and decommissioning (D ampersand D), remedial action (RA), and WM activities. The TLD consists of three fundamentally separate volumes: Vol. 1, Technology Evaluation; Vol. 2, Technology Logic Diagram and Vol. 3, Technology EvaLuation Data Sheets. Part A of Vols. 1 and 2 focuses on RA. Part B of Vols. 1 and 2 focuses on the D ampersand D of contaminated facilities. Part C of Vols. 1 and 2 focuses on WM. Each part of Vol. 1 contains an overview of the TM, an explanation of the problems facing the volume-specific program, a review of identified technologies, and rankings of technologies applicable to the site. Volume 2 (Pts. A. B. and C) contains the logic linkages among EM goals, environmental problems, and the various technologies that have the potential to solve these problems. Volume 3 (Pts. A. B, and C) contains the TLD data sheets. This volume provides the technology evaluation data sheets (TEDS) for ER/WM activities (D ampersand D, RA and WM) that are referenced by a TEDS code number in Vol. 2 of the TLD. Each of these sheets represents a single logic trace across the TLD. These sheets contain more detail than is given for the technologies in Vol. 2

  1. Health Technology Assessment - science or art?

    Hofmann, Bjørn

    2013-01-01

    The founding disciplines of HTA are clearly scientific, and have been firmly based among the natural sciences. However, common definitions of HTA indicate that HTA is something more than the "pure application of science". This article investigates whether this "something" also makes HTA an art. The question of whether HTA is a science or an art is pursued in two specific and historically rich directions. The first is whether HTA is an art in the same way that medicine is described as an art. It has been argued extensively that medicine is based on two different and partly incompatible cultures, i.e., the natural sciences and humanities. Medicine is based on disciplines within the natural sciences, while its value judgments have been placed in the humanities camp. This dichotomy is present in HTA as well, and the first part of the investigation illustrates how HTA is an art in terms of its inherent and constitutive value-judgments. The second part of the science/art-scrutiny leads us to the ancient (Hippocratic) concept of art, téchne, where we find an etymological and a conceptual link between HTA and art. It demonstrates HTA is not an arbitrary process, even though it involves value judgments and relates complex decision making processes. As an art (téchne) HTA has a specific subject matter, requires inquiry and mastery of general rational principles, and is oriented to a specific end. In conclusion, the science-or-art-question makes sense in two specific perspectives, illustrating that HTA is a science based art. This has implications for the practice of HTA, for its education, and for the status of its results.

    Full Text Available This work discuss on digital art and its preservation. Being a kind of art recognized as born digital, it is among the field of contemporary art and the wide field of digital technology. At the same time, it is part of a society in which the technology has established itself worldwide providing means to criticize the idea of "digital" as advancement or progress. Based on those assumptions, we have tried to think about the complexity of that artistic expression which is manifested in its preservation. In this article, which features notes derived from research on art and its preservation, we seek to think on the relationship between art and data and how the preservation effort beyond the data (informational/computational of technological art work reveals its statute from its industrial and artistic composition.

    Canada has developed a unique nuclear power system, the CANDU reactor. AECL - Research Company (AECL-RC) has played a key role in the CANDU program by supplying its technology to the reactor's designers, constructors and operators. This technology was transferred from our laboratories to our sister AECL companies and to domestic industries and utilities. As CANDUs were built overseas, AECL-RC made its technology available to foreign utilities and agencies. Recently the company has embarked on a new transfer program, commercial R and D for nuclear and non-nuclear customers. During the years of CANDU development, AECL-RC has acquired the skills and technology that are especially valuable to other countries embarking on their own nuclear programs. This report describes AECL-RC's thirty years' experience with the transfer of technology

    Ahmed, Salah Uddin; Camerano, Cristoforo; Fortuna, Luigi; Frasca, Mattia; Jaccheri, Letizia

    The interaction between information technology (IT) and art is an increasing trend. Science, art and technology have been connected since the 60's, when scientists, artists, and inventors started to cooperate and use electronic instruments to create art. In 1960 Marshall McLuhan predicted the idea that the era of "machine-age" technology was next to close, and the electronic media were creating a new way to perform art [1]. The literature is full with examples of artists applying mathematics, robotic technology, and computing to the creation of art. The work in [2] is a good introduction to the merge of IT and art and introduces genetic art, algorithmic art, applications of complex systems and artificial intelligence. The intersection is drawing attention of people from diverse background and it is growing in size and scope. For these reasons, it is beneficiary for people interested in art and technology to know each other's background and interests well. In a multidisciplinary collaboration, the success depends on how well the different actors in the project collaborate and understand each other. See [3] for an introduction about multidisciplinary issues. Meyer and others in [4] explains the collaboration process between artists and technologists.

    Sandia National Laboratories Environmental Restoration Technologies Department is developing environmental restoration technologies through funding form the US Department of Energy`s (DOE`s) Office of Science and Technology. Initially, this technology development has been through the Mixed Waste Landfill Integrated Demonstration (MWLID). It is currently being developed through the Contaminant Plume containment and Remediation Focus Area, the Landfill Stabilization Focus Area, and the Characterization, Monitoring, and Sensor Cross-Cutting Program. This Technology Integration Project (TIP) was responsible for transferring MWLID-developed technologies for routine use by environmental restoration groups throughout the DOE complex and commercializing these technologies to the private sector. The MWLID`s technology transfer/commercialization successes were achieved by involving private industry in development, demonstration, and technology transfer/commercialization activities; gathering and disseminating information about MWLID activities and technologies; and promoting stakeholder and regulatory involvement. From FY91 through FY95, 30 Technical Task Plans (TTPs) were funded. From these TTPs, the MWLID can claim 15 technology transfer/commercialization successes. Another seven technology transfer/commercialization successes are expected. With the changeover to the focus areas, the TIP continued the technology transfer/commercialization efforts begun under the MWLID.

    2013-12-01

    Since its inception in 19th-century Germany, the physiology laboratory has been a complex and expensive research enterprise involving experts in various fields of science and engineering. Physiology research has been critically dependent on cutting-edge technological support of mechanical, electrical, optical, and more recently computer engineers. Evolution of modern experimental equipment is constrained by lack of direct communication between the physiological community and industry producing this equipment. Fortunately, recent advances in open source technologies, including three-dimensional printing, open source hardware and software, present an exciting opportunity to bring the design and development of research instrumentation to the end user, i.e., life scientists. Here we provide an overview on how to develop customized, cost-effective experimental equipment for physiology laboratories.

  11. Computer technology forecasting at the National Laboratories

    International Nuclear Information System (INIS)

    Peskin, A.M.

    1980-01-01

    The DOE Office of ADP Management organized a group of scientists and computer professionals, mostly from their own national laboratories, to prepare an annually updated technology forecast to accompany the Department's five-year ADP Plan. The activities of the task force were originally reported in an informal presentation made at the ACM Conference in 1978. This presentation represents an update of that report. It also deals with the process of applying the results obtained at a particular computing center, Brookhaven National Laboratory. Computer technology forecasting is a difficult and hazardous endeavor, but it can reap considerable advantage. The forecast performed on an industry-wide basis can be applied to the particular needs of a given installation, and thus give installation managers considerable guidance in planning. A beneficial side effect of this process is that it forces installation managers, who might otherwise tend to preoccupy themselves with immediate problems, to focus on longer term goals and means to their ends

    2013-01-01

    Full Text Available The paper substantiates the introduction of interactive techniques in music and arts education, and analyzes the definitions of interactivity – a key term of the modern educational paradigm. Various interpretationsof interactivity and its components – interaction, communication, dia logue, polylogue, interpretation, reinterpretation, intonation, feelings, comprehension, generalization (reflection, and experience – are given. In the methodology context, the author traces out the similarity of interactive concepts in general didactics and the humanities knowledge (M. M. Bakhtin, V. S. Bibler, and maintains that the main components of interactive teaching include the basic categories of culture, art, music, and psychology of artistic perception and creativity. Therefore, similarity of the content and approach to interpreting the conceptual terminological apparatus of interactive education makes it possible to implement the interactive techniques in teaching the cycle of music and arts disciplines.

  17. Technology transfer present and futures in the electronic arts

    Directory of Open Access Journals (Sweden)

    Brian Degger

    2008-01-01

    Full Text Available We are entering an era where creating the fantastical is possible in the arts. In the areas of mixed reality and biological arts, responsive works are created based on advances in basic science and technology. This is enabling scientists and artists to pose new questions. As the time between discovery and application is so short, artists need imaginative ways of accessing new technology in order to critique and use it.These are the new paints that the majority of artists cannot afford or access, technology to enable cloning of DNA, to print channels on a chip, to access proprietary 3G networks. Currently, partnerships or residencies are used to facilitate artist’s access to these technologies. What would they do if technology was available that enabled them to make any art work they so desire? Are the limitations in current technology an advantage rather than a disadvantage in some of their works? Does interaction with technologists make their work more robust? Are there disadvantages? How do they get access to the technology they require? Open source or proprietary? Or have they encountered the situation where their vision is greater than technology allows. When their work breaks because of this fact, is their art broken? Blast Theory (Brighton,UK, FoAM(Brussels, Belgium and Amsterdam, Netherlands, SymbioticA (Perth, Australia are organisations pushing technological boundaries in the service of art. This paper addresses some questions of technology transfer in relation to recent artworks, particularly I like Frank in Adelaide (Blast Theory, transient reality generators (trg (FoAM and Multi electrode array artist (MeART (SymbioticA.

  20. A Modest Art: Securing Privacy in Technologically Mediated Homecare.

    Science.gov (United States)

    Kamphof, Ike

    2017-01-01

    This article addresses the art of living in a technological culture as the active engagement with technomoral change. It argues that this engagement does not just take the form of overt deliberation. It shows in more modest ways as reflection-in-action, an experimental process in which new technology is fitted into existing practices. In this process challenged values are re-articulated in pragmatic solutions to the problem of working with new technology. This art of working with technology is also modest in the sense that it is not oriented to shaping one's own subjectivity in relation to technology. It emanates from human existence as relational and aims at securing good relationships. The argument will be developed in relation to a case study of the ways in which homecare workers engaged with the value of privacy, challenged by tele-monitoring technology that was newly introduced into their work.

  1. Push technology at Argonne National Laboratory.

    Energy Technology Data Exchange (ETDEWEB)

    Noel, R. E.; Woell, Y. N.

    1999-04-06

    Selective dissemination of information (SDI) services, also referred to as current awareness searches, are usually provided by periodically running computer programs (personal profiles) against a cumulative database or databases. This concept of pushing relevant content to users has long been integral to librarianship. Librarians traditionally turned to information companies to implement these searches for their users in business, academia, and the science community. This paper describes how a push technology was implemented on a large scale for scientists and engineers at Argonne National Laboratory, explains some of the challenges to designers/maintainers, and identifies the positive effects that SDI seems to be having on users. Argonne purchases the Institute for Scientific Information (ISI) Current Contents data (all subject areas except Humanities), and scientists no longer need to turn to outside companies for reliable SDI service. Argonne's database and its customized services are known as ACCESS (Argonne-University of Chicago Current Contents Electronic Search Service).

    International Nuclear Information System (INIS)

    Bixel, J.C.; Kershner, C.J.; Rhinehammer, T.B.

    1975-01-01

    Over the past four years, implementation of tritium waste control programs has resulted in a 30-fold reduction in the gaseous tritium effluents from Mound Laboratory. However, to reduce tritium waste levels to the ''as low as practicable'' guideline poses problems that are beyond ready solution with state-of-the-art tritium control technology. To meet this advanced technology need, a tritium waste control technology program was initiated. Although the initial thrust of the work under this program was oriented toward development of gaseous effluent treatment systems, its natural evolution has been toward the liquid waste problem. It is thought that, of all the possible approaches to disposal of tritiated liquid wastes, recovery offers the greatest advantages. End products of the recovery processes would be water detritiated to a level below the Radioactivity Concentration Guide (RCG) or detritiated to a level that would permit safe recycle in a closed loop operation and enriched tritium. The detritiated water effluent could be either recycled in a closed loop operation such as in a fuel reprocessing plant or safely released to the biosphere, and the recovered tritium could be recycled for use in fusion reactor studies or other applications

    Use of assisted reproductive technology has increased steadily, yet multiple socioeconomic and demographic disparities remain between the general population and those with infertility. Additionally, both mothers and infants experience higher rates of adverse outcomes compared to their non-ART counterparts. Using International Classification of Diseases, Ninth Revision (ICD-9) coding, we performed a retrospective review of all ART-conceived deliveries in California in 2009. A total of 551 ART pregnancies were compared to Non-ART pregnancies (n=406,885). The majority of ART deliveries belonged to women of advanced maternal age (AMA) and Caucasian or Asian race. Nearly half of all ART deliveries were multiple gestations. Compared to non-ART deliveries, ART pregnancies were associated with placenta previa, placental abruption, mild preeclampsia, and fetal growth restriction. While not powered to detect all outcomes, our study highlights significant racial and ethnic disparities between ART and Non-ART pregnancies.

    Nowadays, many infertile couples can have child by assistant reproductive technology (ART). Always the undesirable effects of these methods on newborn are considered and are evaluated. The aim of this study is to describe the impact of ART on ocular and visual performances of infants born by these methods. In a cross-sectional descriptive study, 479 infants aged three-nine months presented to an optometry clinic of Child Health and Development Research Department (CHDRD), Tehran, Iran. Static retinoscopy, qualitative fixation evaluation, Hirschberg test, red reflex assessment and external eye examination were carried out. Other information such as birth weight and maturity of the infants was recorded. It was possible to assess only 320 out of 479 infants due to general condition of some participants. Comparison of mean refractive error in infants' right and left eyes did not show any significant difference. Our findings confirmed that 20.3% had poor fixation, while 2.9% revealed manifest strabismus. The results also revealed the prevalences of myopia, hyperopia and emmetropia are 2.9%, 87%, and 10.1%, respectively. Red reflex abnormalities were significantly found in boys and in preterm infants (p ART, especially for premature male ART infants. These results also suggest the probability of fixation condition and visual deficiencies in these infants. It is recommended to pay close attention to this preliminary report about the refractive and fixation condition of the infants born after ART.

    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.

This is especially true in regions where the high quality standards of wine production justify the adoption of site-specific management practices to simultaneously increase both quality and yield. The introduction of new technologies for supporting vineyard management allows the efficiency and quality of production to be improved and, at the same time, reduces the environmental impact. The rapid evolution of information communication technologies and geographical science offers enormous potential for the development of optimized solutions for distributed information for precision viticulture. Recent technological developments have allowed useful tools to be elaborated that help in the monitoring and control of many aspects of vine growth. Precision viticulture thus seeks to exploit the widest range of available observations to describe the vineyard spatial variability with high resolution, and provide recommendations to improve management efficiency in terms of quality, production, and sustainability. This review presents a brief outline of state of the art of technologies in precision viticulture. It is divided in two sections, the first focusing on monitoring technologies such as geolocating and remote and proximal sensing; the second focuses on variable-rate technologies and the new agricultural robots. Keywords: remote sensing, proximal sensing, variable-rate technology, robot

    In Turkey, as in many other countries, infertility is generally regarded as a negative phenomenon in a woman's life and is associated with a lot of stigma by society. In other words, female infertility and having a baby using Assisted Reproductive Technologies (ART) have to be taken into consideration with respect to gender motherhood, social factors, religion and law. Yet if a woman chooses to use ART she has to deal with the consequences of her decision, such as being ostracized by society. Other types of procedures in this area, such as sperm and ova donation or surrogate motherhood, are not permitted in law. However; both before and after the development of this techonology, society has been finding its own solutions which are rarely questioned and are still performed This article will discuss what these practices are and try to reach some pragmatic conclusions concerning female infertility, the concept of motherhood and some traditional practices in Turkey.

    Full Text Available Nowadays, many infertile couples can have child by assistant reproductive technology (ART. Always the undesirable effects of these methods on newborn are considered and are evaluated. The aim of this study is to describe the impact of ART on ocular and visual performances of infants born by these methods.In a cross-sectional descriptive study, 479 infants aged three-nine months presented to an optometry clinic of Child Health and Development Research Department (CHDRD, Tehran, Iran. Static retinoscopy, qualitative fixation evaluation, Hirschberg test, red reflex assessment and external eye examination were carried out. Other information such as birth weight and maturity of the infants was recorded.It was possible to assess only 320 out of 479 infants due to general condition of some participants. Comparison of mean refractive error in infants' right and left eyes did not show any significant difference. Our findings confirmed that 20.3% had poor fixation, while 2.9% revealed manifest strabismus. The results also revealed the prevalences of myopia, hyperopia and emmetropia are 2.9%, 87%, and 10.1%, respectively. Red reflex abnormalities were significantly found in boys and in preterm infants (p < 0.05. Failure of fixation control was seen more frequently with increasing refractive error, which significantly developed in preterm infants (p < 0.001.These results reflect the necessity of more comprehensive assessments and further follow-up of infants born by ART, especially for premature male ART infants. These results also suggest the probability of fixation condition and visual deficiencies in these infants. It is recommended to pay close attention to this preliminary report about the refractive and fixation condition of the infants born after ART.

    In the modern educational framework, life science and visual art are usually presented as mutually exclusive subjects. Despite this perceived disciplinary contrast, visual art has the ability to engage and provoke students in ways that can have important downstream effects on scientific discovery, especially when applied in a practical setting such as a laboratory course. This review broadly examines the benefit of interdisciplinary fusions of science and art as well as recent ways in which art strategies have been used in undergraduate biology classrooms. In a case study, we found that undergraduate students in an introductory microbiology laboratory course who participated in open-inquiry activities involving agar art had greater confidence in their personal efficacy as scientists compared to a control class. Collectively, these observations suggest that visual art can be a useful enhancement in the course-based undergraduate research setting, and science educators at all levels should consider incorporating artistic creativity in their own classroom strategies. © FEMS 2017.

  14. IN A PARALLEL UNIVERSE: HOW ART EXPLOITS TECHNOLOGY

    CERN Multimedia

    CERN. Geneva

    2012-01-01

    Technical innovation in the arts creates new opportunities for perceptual shifts that lead to lasting achievements. One of the most important events took place in the 15th century not far from CERN on the other side of the Alps in Venice. Titian, in one life time, exploited these new material developments to expand the range of expression like no other artist of his generation. Titian was able to harness these new innovations to emerge as the supreme competitor and hustler, a notion that seems very much a part of the modern promotion of art as exemplified by Warhol , Jeff Koons and Damian Hirst. The language of science and technology has created social networks, changed the mediums and the subject of fine art. Fast forward to CERN 2012, the most expensive experiment in the history of science. The knowledge of dark matter will either help confirm, or not, the Standard Model. This information will be part of what Michel Foucault calls "epistemological breaks", shifts in consciousness that change our p...

    The Decontamination and Decommissioning (D&D) Index provides a comprehensive list of site problems, problem area/constituents, remedial technologies, and regulatory terms discussed in the D&D sections of the Oak Ridge National Laboratory Technology Logic Diagram. All entries provide specific page numbers, or cross-reference entries that provide specific page numbers, in the D&D volumes (Vol. 1, Pt. A; Vol. 2, Pt. A; and appropriate parts of Vol. 3). The Oak Ridge National Laboratory Technology (TLD) was developed to provide a decision-support tool that relates environmental restoration (ER) and waste management (WM) problems at Oak Ridge National Laboratory (ORNL) to potential technologies that can remediate these problems. The TLD identifies the research, development, demonstration, testing, and evaluation needed to develop these technologies to a state that allows technology transfer and application to decontamination and decommissioning (D&D), remedial action (RA) and WM activities. It is essential that follow-on engineering studies be conducted to build on the output of this project. These studies will begin by selecting the most promising technologies identified in the TLD and finding an optimum mix of technologies that will provide a socially acceptable balance between cost and risk.

    Modern dentistry and dental education in China were first introduced from abroad by Dr. Lindsay in 1907. However, advancements in the field of dental laboratory technology did not occur to the same degree in specialties such as prosthodontics and orthodontics. Since the 1990s, orders from abroad demanding dental appliances surged as the image of China as the "world's factory" strengthened. The assembly line model, in which technicians work like simple procedure workers, was rapidly applied to denture production, while the traditional education system and apprenticeship systems demonstrated little progress in these years. The lack of advancement in dental laboratory technology education caused insufficient development in China's dental technology industry. In order to alter the situation, a four-year dental laboratory technology undergraduate educational program was established in 2005 by West China School of Stomatology, Sichuan University (WCSS, SCU). This program was based on SCU's undergraduate education and WCSS's junior college education systems. The program introduced scientific methods in relevant subjects into laboratory technicians' training and made many improvements in the availability of trained faculty, textbooks, laboratory facilities, and curriculum.

    Since worldwide interest turned toward ceramic fuels before the full potential of metallic fuel could be achieved in the late 1960`s, the development of metallic fuels continued throughout the 1970`s at ANL`s experimental breeder reactor II (EBR-II) because EBR-II continued to be fueled with the metallic uranium-fissium alloy, U-5Fs. During this decade the performance limitations of metallic fuel were satisfactorily resolved resolved at EBR-II. The concept of the IFR developed at ANL since 1984. The technical feasibility had been demonstrated and the technology database had been established to support its practicality. One key features of the IFR is that the fuel is metallic, which brings pronounced benefits over oxide in improved inherent safety and lower processing costs. At the outset of the 1980`s, it appeared that metallic fuels are recognized as a professed viable option with regard to safety, integral fuel cycle, waste minimization and deployment economics. This paper reviews the key advances in the last score and summarizes the state-of the art on metallic fuel technology development. (author). 29 refs., 1 tab.

    In the field of assisted reproductive technology (ART), medical accidents can result in serious legal and social consequences. This study was conducted to develop a security system (called IVF-guardian; IG) that could prevent mismatching or mix-ups in ART. A software program was developed in collaboration with outside computer programmers. A quick response (QR) code was used to identify the patients, gametes and embryos in a format that was printed on a label. There was a possibility that embryo development could be affected by volatile organic components (VOC) in the printing material and adhesive material in the label paper. Further, LED light was used as the light source to recognize the QR code. Using mouse embryos, the effects of the label paper and LED light were examined. The stability of IG was assessed when applied in clinical practice after developing the system. A total of 104 cycles formed the study group, and 82 cycles (from patients who did not want to use IG because of safety concerns and lack of confidence in the security system) to which IG was not applied comprised the control group. Many of the label paper samples were toxic to mouse embryo development. We selected a particular label paper (P touch label) that did not affect mouse embryo development. The LED lights were non-toxic to the development of the mouse embryos under any experimental conditions. There were no differences in the clinical pregnancy rates between the IG-applied group and the control group (40/104 = 38.5 % and 30/82 = 36.6 %, respectively). The application of IG in clinical practice did not affect human embryo development or clinical outcomes. The use of IG reduces the misspelling of patient names. Using IG, there was a disadvantage in that each treatment step became more complicated, but the medical staff improved and became sufficiently confident in ART to offset this disadvantage. Patients who received treatment using the IG system also went through a somewhat

    The new French law about clinical laboratory medicine, the requirements of the ISO/CEI 15189 standard, the numerous abilities expected from the medical laboratory technologists and their involvement in blood bank management has led the working group "Recherche et démarche qualité" of the French Society of Blood Transfusion to initiate an inventory of blood transfusion teaching syllabus for medical laboratory technology students and to propose transfusion medicine teaching guidelines. Seven worksheets have been established for that purpose including red blood cell antigen typing and antibody screening, blood sampling in immunohaematology, automation, clinical practices, blood products, blood delivery and haemovigilance. These guidelines aim at contributing to the harmonization of transfusion medicine teaching and at providing objective elements to the medical laboratory managers regarding the practical and theoretical skills of theirs collaborators.

    This descriptive study was carried out to assess the awareness and acceptability of Assisted Reproductive Technology (ART) among infertile women in Lagos, Nigeria. Self-administered questionnaires on the knowledge of ART in the women were used. After a brief exposé on ART, questions relating to their attitude were answered. A total of 166 women were studied. Only 51.8% had any knowledge of ART and most of these had poor knowledge. A total of 137 women would embrace ART if offered but 29 would not, for reasons such as religion, fear of side-effects, failure and unaffordable costs. There is a paucity of good knowledge of ART. A significant number of the women would consider ART if offered. There is thus a need to create more awareness about the possibilities offered by ART, as well as instituting low cost ART strategies in developing world countries.

    The Laboratory Technology Research (LTR) program supports high-risk, multidisciplinary research partnerships to investigate challenging scientific problems whose solutions have promising commercial potential. These partnerships capitalize on two great strengths of this country: the world-class basic research capability of the DOE Energy Research (ER) multi-program national laboratories and the unparalleled entrepreneurial spirit of American industry. A distinguishing feature of the ER multi-program national laboratories is their ability to integrate broad areas of science and engineering in support of national research and development goals. The LTR program leverages this strength for the Nation`s benefit by fostering partnerships with US industry. The partners jointly bring technology research to a point where industry or the Department`s technology development programs can pursue final development and commercialization. Projects supported by the LTR program are conducted by the five ER multi-program laboratories. These projects explore the applications of basic research advances relevant to DOE`s mission over a full range of scientific disciplines. The program presently emphasizes three critical areas of mission-related research: advanced materials; intelligent processing/manufacturing research; and sustainable environments.

    This review is directed at physicians and laboratory personnel in private practice and clinics who treat and diagnose Lyme borreliosis (LB) in patients as part of their daily work. A major objective of this paper is to bring together background information on Borrelia (B.) burgdorferi sensu lato (s.l.) and basic clinical knowledge of LB, which is one of the most frequently reported vector-borne diseases in the Northern Hemisphere. The goal is to provide practical guidance for clinicians and for laboratory physicians, and scientists for a better understanding of current achievements and ongoing obstacles in the laboratory diagnosis of LB, an infectious disease that still remains one of the diagnostic chameleons of modern clinical medicine. Moreover, in bringing together current scientific information from guidelines, reviews, and original papers, this review provides recommendations for selecting the appropriate tests in relation to the patient's stage of disease to achieve effective, stage-related application of current direct and indirect laboratory methods for the detection of B. burgdorferi s.l. Additionally, the review aims to discuss the current state of the art concerning the diagnostic potential and limitations of the assays and test methods currently in use to optimize LB patient management and provide insight into the possible future prospects of this rapidly changing area of laboratory medicine.

    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.

    The Health Technology Assessment (HTA) is a multi-professional and multidisciplinary evaluation approach designed to assess health technology in the broadest sense of the term, from its instruments to the rearranging of its organizational structures. It is by now an established methodology at national and international levels that involves several medical disciplines thanks to its versatility. Laboratory medicine is one of these disciplines. Such specialization was subjected, in recent years, to deep changes even from an organizational standpoint, in order to meet the health needs of the population, making them as effective and cost-effective as possible. In this regard, HTA was the tool used to assess implications in different areas.

    Human reproduction has benefited significantly by investigating non-human primate (NHP) models, especially rhesus macaques. To expand the Old World monkey species available for human reproductive studies, we present protocols in baboons, our closest Old World primate relatives, for Assisted Reproductive Technologies (ART) leading to live-born offspring. Baboons complement rhesus by confirming or modifying observations generated in humans often obtained by the study of clinically-discarded specimens donated by anonymous infertility patient-couples. Here, baboon ART protocols, including oocyte collection, in vitro fertilization, intracytoplasmic sperm injection (ICSI), preimplantation development to blastocyst stage and embryo transfer techniques are described. With baboon ART methodologies in place, motility during baboon fertilization was investigated by time-lapse video microscopy. The first ART baboons produced by ICSI, a pair of male twins, were delivered naturally at 165 days post-gestation. Genetic testing of these twins confirmed their ART parental origins and demonstrated that they are unrelated fraternal twins, not identicals. These results have implications for ART outcomes, embryonic stem cell derivation, and reproductive sciences. PMID:20631291

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

  7. Converging technologies in higher education: paradigm for the "new" liberal arts?

    Science.gov (United States)

    Balmer, Robert T

    2006-12-01

    This article discusses the historic relationship between the practical arts (technology) and the mental (liberal) arts, suggesting that Converging Technologies is a new higher education paradigm that integrates the arts, humanities, and sciences with modern technology. It explains that the paradigm really includes all fields in higher education from philosophy to art to music to modern languages and beyond. To implement a transformation of this magnitude, it is necessary to understand the psychology of change in academia. Union College in Schenectady, New York, implemented a Converging Technologies Educational Paradigm in five steps: (1) create a compelling vision, (2) communicate the vision, (3) empower the faculty, (4) create short-term successes, and (5) institutionalize the results. This case study of Union College demonstrates it is possible to build a pillar of educational excellence based on Converging Technologies.

    More than 25 laboratories of the European Fusion Development Agreement (EFDA) have been increasingly using remote participation (RP) technologies for collaborative work on several experiments. We present an overview of the technologies that are employed to provide remote data access, remote computer access, and tele-conference. We also deal with computer network requirements, and support and documentation needs. The biggest application of these tools has been the joint scientific exploitation of the JET Facilities. Increasingly other experiments are operated as shared facilities, and the RP tools are being used in this context. For remote data access there is a clear trend towards MDSplus as common data access layer for multi-experiment data access. Secure Remote Computer access is converging on two different solutions. Video-conference is also converging on two partially inter-operable solutions, whereas the sharing of presentation material is converging on one solution. Remote Control Room participation is being used in two laboratories. Network monitoring has been developed and is now in routine use. The RP work is being done at many laboratories and is co-ordinated by EFDA. A number of items in several fields need still to be tackled and an overview of these is presented. (authors)

    Instructions for authors (IFA) need to be informative and regularly updated. We hypothesized that journals with a higher impact factor (IF) have more comprehensive IFA. The aim of the study was to examine whether IFA of journals indexed in the Journal Citation Reports 2013, "Medical Laboratory Technology" category, are written in accordance with the latest recommendations and whether the quality of instructions correlates with the journals' IF. 6 out of 31 journals indexed in "Medical Laboratory Technology" category were excluded (unsuitable or unavailable instructions). The remaining 25 journals were scored based on a set of 41 yes/no questions (score 1/0) and divided into four groups (editorial policy, research ethics, research integrity, manuscript preparation) by three authors independently (max score = 41). We tested the correlation between IF and total score and the difference between scores in separate question groups. The median total score was 26 (21-30) [portion of positive answers 0.63 (0.51-0.73)]. There was no statistically significant correlation between a journal's IF and the total score (rho = 0.291, P = 0.159). IFA included recommendations concerning research ethics and manuscript preparation more extensively than recommendations concerning editorial policy and research integrity (Ht = 15.91, P = 0.003). Some policies were poorly described (portion of positive answers), for example: procedure for author's appeal (0.04), editorial submissions (0.08), appointed body for research integrity issues (0.08). The IF of the "Medical Laboratory Technology" journals does not reflect a journals' compliance to uniform standards. There is a need for improving editorial policies and the policies on research integrity.

    2017-06-01

    Full Text Available This paper presents a blended-learning strategy for improving the teaching method applied in the laboratory subject Manufacturing Technologies. The teaching method has been changed from a predominantly teacher-centred to an active learning system with a student-centred focus and e-learning activities. In face-to-face classes, a game-based learning platform has been used. This methodology ensured engaging classes at the same time that provided a useful live feedback for students and teachers. The virtualization of the laboratory was achieved by two different e-learning activities, self-assessment tasks and video clips. These e-learning tools have been used not only to improve the students’ learning but also to enhance their motivation. The results from academic outputs show a significant improvement after the new blended learning method is applied. Moreover, a student satisfaction survey shows the positive impact of the methodology on the students’ engagement and motivation.

    This study is based on observed outcomes of motivation sources and collaboration elements from a living lab style co-operation project. In this project, researchers of engineering science and an individual artist co-operated closely. The goal was to create an artwork made from corrugated board by utilizing laser cutting technology. In the context of this study, the scientist and the artist participated in the whole process and the research was done in living lab style arrangement. The research process integrated multiple experts from different scientific fields and experts from practical contexts to develop a new art design and art forming process with utilization of laser cutting technology. The purpose of this study was to find out and discuss about the key elements for high motivation to work together and then reveal the best practice findings in this co-operative development process. Elements were studied from three different points of view: artists view, collaboration motivation view and practical cutting point of view. The elements were analysed by utilizing an active documentation collection methodology, during the whole process, and by using story-telling methodology. The documents were used to reflect facts and feelings from the co-operation, the work process and the challenges encountered within collaboration. This article contributes to research methodology and best practice context by revealing the key elements, which build the motivation compelling (as personal inner motivation) the participant to work out of office hours as well as on weekends. Furthermore, as the artist-engineer co-operation is not frequently reported in scientific literature, this study reveals valuable information for practitioners and co-operation researchers.

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

    2011-01-01

    The state of the art for predicting climate changes due to increasing greenhouse gasses in the atmosphere with high accuracy is problematic. Confidence intervals on current long-term predictions (on the order of 100 years) are so large that the ability to make informed decisions with regard to optimum strategies for mitigating both the causes of climate change and its effects is in doubt. There is ample evidence in the literature that large sources of uncertainty in current climate models are various aerosol effects. One approach to furthering discovery as well as modeling, and verification and validation (V&V) for cloud-aerosol interactions is use of a large "cloud chamber" in a complimentary role to in-situ and remote sensing measurement approaches. Reproducing all of the complex interactions is not feasible, but it is suggested that the physics of certain key processes can be established in a laboratory setting so that relevant fluid-dynamic and cloud-aerosol phenomena can be experimentally simulated and studied in a controlled environment. This report presents a high-level argument for significantly improved laboratory capability, and is meant to serve as a starting point for stimulating discussion within the climate science and other interested communities.

    Full Text Available This paper studies the technological capability in the Brazilian Official Pharmaceutical Laboratories [OPL]. The technological capability analysis could contribute to organization strategies and governmental actions in order to improve OPL basic tasks as well to incorporate new ones, particularly concerning the innovation management. Inspired in Figueiredo (2000, 2003a, 2003b and Figueiredo and Ariffin (2003, a framework was drawn and adapted to pharmaceutical industry characteristics and current sanitary and health legislation. The framework allows to map different dimensions of the technological capability (installations, processes, products, equipments, organizational capability and knowledge management and the level attained by OPL (ordinary or innovating capability. OPL show a good development of ordinary capabilities, particularly in Product and Processes. Concerning the other dimensions, OPL are quite diverse. In general, innovating capabilities are not much developed. In the short term, it was identified a dispersion in the capacitating efforts. Considering their present level and the absorption efforts, good perspectives can be found in Installations, Processes and Organizational Capability. A lower level of efforts in Products and Knowledge Management could undermine these capabilities in the future.

    Energy Technology Data Exchange (ETDEWEB)

    1993-09-01

    The Oak Ridge National Laboratory Technology Logic Diagram (TLD) was developed to provide a decision-support tool that relates environmental restoration (ER) and waste management (WM) problems at Oak Ridge National Laboratory (ORNL) to potential technologies that can remediate these problems. The TLD identifies the research, development, demonstration, testing, and evaluation needed to develop these technologies to a state that allows technology transfer and application to decontamination and decommissioning (D&D), remedial action (RA), and WM activities. The TLD consists of three fundamentally separate volumes: Vol. 1 (Technology Evaluation), Vol. 2 (Technology Logic Diagram), and Vol. 3 (Technology Evaluation Data Sheets). Part A of Vols. 1 and 2 focuses on D&D. Part B of Vols. 1 and 2 focuses on RA of contaminated facilities. Part C of Vols. 1 and 2 focuses on WM. Each part of Vol. 1 contains an overview of the TLD, an explanation of the program-specific responsibilities, a review of identified technologies, and the ranking os remedial technologies. Volume 2 (Pts. A, B, and C) contains the logic linkages among EM goals, environmental problems, and the various technologies that have the potential to solve these problems. Volume 3 (Pts. A, B, and C) contains the TLD data sheets. The focus of Vol. 1, Pt. B, is RA, and it has been divided into six chapters. The first chapter is an introduction, which defines problems specific to the ER Program for ORNL. Chapter 2 provides a general overview of the TLD. Chapters 3 through 5 are organized into necessary subelement categories: RA, characterization, and robotics and automation. The final chapter contains regulatory compliance information concerning RA.

    Are assisted reproductive technology (ART) treatment factors or infertility diagnoses associated with autism among ART-conceived children? Our study suggests that the incidence of autism diagnosis in ART-conceived children during the first 5 years of life was higher when intracytoplasmic sperm injection (ICSI) was used compared with conventional IVF, and lower when parents had unexplained infertility (among singletons) or tubal factor infertility (among multiples) compared with other types of infertility. Some studies found an increased risk of autism among ART-conceived infants compared with spontaneously-conceived infants. However, few studies, and none in the USA, have examined the associations between types of ART procedures and parental infertility diagnoses with autism among ART-conceived children. Population-based retrospective cohort study using linkages between National ART Surveillance System (NASS) data for 1996-2006, California Birth Certificate data for 1997-2006, and California Department of Developmental Services (DDS) Autism Caseload data for 1997-2011. All live born ART-conceived infants born in California in 1997-2006 (n = 42 383) with 5-year observation period were included in the study. We assessed the annual incidence of autism diagnosis documented in DDS, which includes information on the vast majority of persons with autism in California, and the association of autism diagnosis with ART treatment factors and infertility diagnoses. Among ART-conceived singletons born in California between 1997 and 2006, the incidence of autism diagnosis remained at ∼0.8% (P for trend 0.19) and was lower with parental diagnosis of unexplained infertility (adjusted hazard risk ratio [aHRR]; 95% confidence interval: 0.38; 0.15-0.94) and higher when ICSI was used (aHRR 1.65; 1.08-2.52), when compared with cases without these patient and treatment characteristics. Among ART-conceived multiples, the incidence of autism diagnosis between 1997 and 2006 remained at

    Risk and safety management (RSM) is receiving increasing attention in medicine, with the goals of reducing medical error and increasing quality of care. The principles and tools of RSM can and should be applied to assisted reproductive technology (ART), a field that has already made significant progress in reducing the undesirable and sometimes dangerous consequences of treatment. ART is a prime area of medicine to contribute and help to lead the application of RSM and patient safety because it has been ahead of many other fields of medicine in standardizing treatment, certifying and auditing practitioners, and reporting standardized outcomes, and because treatments are applied to otherwise healthy individuals where exposure to risk may be less acceptable.

  4. Development of excavation technologies at the Canadian underground research laboratory

    International Nuclear Information System (INIS)

    Kuzyk, Gregory W.; Martino, Jason B.

    2008-01-01

    Several countries, Canada being among them, are developing concepts for disposal of used fuel from power generating nuclear reactors. As in underground mining operations, the disposal facilities will require excavation of many kilometres of shafts and tunnels through the host rock mass. The need to maintain the stability of excavations and safety of workers will be of paramount importance. Also, excavations required for many radioactive waste repositories will ultimately need to be backfilled and sealed to maintain stability and minimize any potential for migration of radionuclides, should they escape their disposal containers. The method used to excavate the tunnels and shafts, and the rock damage that occurs due to excavation, will greatly affect the performance characteristics of repository sealing systems. The underground rock mechanics and geotechnical engineering work performed at the Canadian Underground Research Laboratory (URL) has led to the development of excavation technologies that reduce rock damage in subsurface excavations. This paper discusses the excavation methods used to construct the URL and their application in planning for the construction of similar underground laboratories and repositories for radioactive wastes.

    Health technology reassessment (HTR) is "a structured, evidence-based assessment of the clinical, social, ethical, and economic effects of a technology currently used in the healthcare system, to inform optimal use of that technology in comparison to its alternatives." The purpose of this study is to describe the key themes in the context of current HTR activities and propose a way forward for this newly emerging field. Data were gathered from a workshop held as part of the 2012 Canadian Agency for Drugs and Technology in Health (CADTH) symposium. The workshop consisted of two panel presentations followed by discussion; data gathered, including presentations and rich audience discussion transcripts, were analyzed for key themes emerging in the field of HTR using constant comparative analysis. The language chosen to describe HTR will set the tone for engagement. The identification of champions at multiple levels and political will are essential. Key lessons from international experience are: disinvestment is difficult, focus on clinical areas not specific technologies, identify clear goals of the HTR agenda. Six key themes were identified to move the HTR agenda forward: emphasize integration over segregation, focus on development of HTR methods and processes, processes are context-specific but lessons must be shared, build capacity in synergistic interdisciplinary fields, develop meaningful stakeholder engagement, strengthen postimplementation monitoring and evaluation. To move this field forward, we must continue to build on international experiences with a focus on developing novel methodological approaches to generating, incorporating, and implementing evidence into policy and practice.

    Full Text Available The study described in this essay explores the use of educational technology as a resource in the Creative Arts classroom. Many teachers are not qualified to teach Creative Arts. They then tend to rely on curriculum documents and textbooks to help guide their planning, teaching and assessment. Most of the teachers who participated in this case study were not specialists in any of the arts, and in the education district where this study took place, there was a lack of ongoing professional development for the Creative Arts. To enable the teachers from Grades R to 7 to mediate more meaningful classroom teaching and learning in the Creative Arts, the researchers introduced the teachers to technology as a means to facilitate learning and teaching. This study follows a phenomenological approach to explore the use of educational technology in the teaching of dance, drama and music, which are three of the art forms in the Creative Arts. The researchers describe the teachers’ perceptions and attitudes towards using technology in the classroom. Eight teachers participated in the study (seven female and one male, ranging in age from 22 to 41 years. There were three teachers from the Foundation Phase, three teachers from the Intermediate Phase and two teachers from the Senior Phase. Data were collected from (1 unstructured open-ended conversational interviews, (2 observations of the participants during contact time with learners and (3 audio-visual recordings of the teachers in the classroom. Findings from the study showed that after the 10-month intervention of using educational technology in the classroom, there was divergence in the teachers’ use of technology. The findings also suggest that classroom practice in dance, drama and music improved.

    Twelve Alaskan elementary and middle school classes (grades 3-8) partnered with twelve Australian middle school classes, with each pair using web-based strategies to develop a collaborative ice-mystery fictional book incorporating authentic polar science. Three professional development workshops were held, bringing together educators and polar scientists in two IPY education outreach projects. The Alaska workshop provided an opportunity to bring together the North American teachers for lessons on arctic and antarctic science and an earth system science program Seasons and Biomes measurement protocols, as well as methods in collaborative e-writing and art in Ice e-Mysteries: Global Student Polar e-books project. Teachers worked with University of Alaska Fairbanks (UAF) and Australian scientists to become familiar with Arctic science research, science artifacts and resources available at UAF and the University of Alaska Museum of the North. In Australia, teachers received a similar project training through the Tasmania Museum and Art Gallery (TMAG) Center for Learning and Discovery on Antarctic science and the University of Tasmania. The long-distance collaboration was accomplished through Skype, emails and a TMAG supported website. A year later, Northern Hemisphere and Southern Hemisphere teacher partners met in a joint workshop in Tasmania, to share their experiences, do project assessments and propose activities for future collaborations. The Australian teachers received training on Seasons and Biomes scientific measurements and the Alaskan teachers, on Tasmanian vegetation, fauna and indigenous culture, Antarctic and Southern ocean studies. This innovative project produced twelve e-polar books written and illustrated by students; heightened scientific literacy about the polar regions and the earth system; increased awareness of the environment and indigenous cultures; stronger connections to the scientific community; and lasting friendships. It also resulted in

    1994-10-01

    Hazardous operations which have in the past been completed by technicians are under increased scrutiny due to high costs and low productivity associated with providing protective clothing and environments. As a result, remote systems are needed to accomplish many hazardous materials handling tasks such as the clean-up of waste sites in which the exposure of personnel to radiation, chemical, explosive and other hazardous constituents is unacceptable. Computer models augmented by sensing, and structured, modular computing environments are proving effective in automating many unstructured hazardous tasks. Work at Sandia National Laboratories (SNL) has focused on applying flexible automation (robotics) to meet the needs of the U.S. Department of Energy (USDOE). Dismantling facilities, environmental remediation, and materials handling in changing, hazardous environments lead to many technical challenges. Computer planning, monitoring and operator assistance shorten training cycles, reduce errors, and speed execution of operations. Robotic systems that re-use well-understood generic technologies can be much better characterized than robotic systems developed for a particular application, leading to a more reliable and safer systems. Further safety in robotic operations results from use of environmental sensors and knowledge of the task and environment. Collision detection and avoidance is achieved from such sensor integration and model-based control. This paper discusses selected technologies developed at SNL for use within the USDOE complex that have been or are ready for transfer to government and industrial suppliers. These technologies include sensors, sub-systems, and the design philosophy applied to quickly integrate them into a working robotic system. This paper represents the work of many people at the Intelligent Systems and Robotics Center at SNL, to whom the credit belongs.

For example, regarding DC to RF and laser converters, 83% efficient 2.45 GHz cooker-tube magnetrons with 800W CW output have been jointly developed by Russia and US. Over 50% wa11-plug efficient 1.5 kW/cm2 CW, water cooled, multibeam, solid state laser diode bar-arrays have been developed by LLNL at 808 nm wavelength. The Gennans have developed a 36% efficient, kW level, sing1e coherent beam, lateral pumped semiconductor laser. The record for end-to-end DC input to DC output power overall WPT link conversion efficiency is 54% during the Raytheon-JPL experiments in 1975 for 495.6 W recovered at 1.7-mrange at 2.4469 GAz. The record for usefully recovered electric power output ( as contrasted with thennally induced power in structures) is 34 kW OC output at a range of 1.55 km, using 2.388 GHz microwaves, during the JPL- Raytheon experiments by Bill Brown and the author at Goldstone, CA in 1975. The GaAs-diode rectenna array had an average collection-conversion efficiency of 82.5%. A single rectenna element operating a 6W RF input, developed by Bill Brown demonstrated 91.4% efficiency. The comparable record for laser light to OC output power conversion efficiency of photovoltaics is 590/0. for AlGaAs at 1.7 Wand 826nm wavelength. Russian cyclotron-wave converters have demonstrated 80% rectification efficiency at S-band. Concerning WPT technology equipment costs, magnetron conversion

    Full Text Available Compared with the conventional casting process, digital pattern-less casting technology has many advantages such as good machining accuracy, a short processing cycle, and low production cost. It is a new rapid manufacturing technology for castings, integrated with CAD/CAM, casting, CNC machining and many other advanced technologies. With this digital casting technology, no pattern is needed for making molds; it is precise, flexible, and green. Usually, art castings have complex structures and are made in small batches or even made in a single-piece, especially for large-sized art castings. So it has the shortcomings of high cost, low efficiency and long time for making a pattern to produce art castings with the conventional casting processes. However, the digital pattern-less casting technology can be applied to fabricate art castings, since it can greatly shorten the manufacturing cycle and lower the production cost, thus having a very good prospect. In this study, based on the digital pattern-less casting technology, a plaque casting with artistic Chinese characters (a Chinese poem was designed and manufactured, and the production process was demonstrated in detail.

    The technology and applications evaluation task focuses on defining performance and cost requirements for flywheels in the various areas of application. To date the DOE program has focused on automotive applications. The composite materials effort entails the testing of new commercial composites to determine their engineering properties. The rotor and containment development work uses data from these program elements to design and fabricate flywheels. The flywheels are then tested and their performance is evaluated to indicate possible areas for improvement. Once a rotor was fully developed it is transferred to the private sector.

    Opportunities in communication satellite technology are identified and defined. Factors that tend to limit the ready availability of satellite communication to an increasingly wide group of users are evaluated. Current primary limitations on this wide utilization are the availability of frequency and/or synchronous equatorial satellite positions and the cost of individual user Earth terminals. The former could be ameliorated through the reuse of frequencies, the use of higher frequency bands, and the reduction of antenna side lobes. The latter limitation requires innovative hardware, design, careful system design, and large scale production.

    The future raw materials are becoming lower in metal content and more complex, multimetal concentrates will be utilized. This will give challenges for metallurgists to develop new, efficient and energy saving processes. The main impacts for current and future production technologies come from energy need and environmental issues of the production processes themselves as well as the inevitable energy production for the metal making. Metals production consumes huge amount of energy, roughly 10 pct of the global energy consumption is caused by metallurgists. That is the necessity but it also means energy saving is one of the metallurgical industry have been enormous when looking back to the history. Since the 1960`s the efforts of the industry together with the strict legislation in the industrialized countries have conducted to greatly decreased emissions and improved pollution control. Breakthrough of new processes like copper flash smelting has aided this positive progress

    CRISPR-Cas9 (clustered regularly interspaced short palindromic repeats-CRISPR associated Protein 9), basically a bacterial immune system is now widely applicable to engineer genomes of a number of cells and organisms because of its simplicity and robustness. In research avenue the system has been optimized to regulate gene expression, modify epigenome and edit target locus. These applications make CRISPR/Cas9, a technology of choice to edit disease causing mutations as well as the epigenome more efficiently than ever before. Meanwhile its application in in vivo and ex vivo cells is encouraging the scientific community for more vigorous gene therapy and in clinical setups for therapeutic genome editing. Here we review the recent advances that CRISPR-Cas9 mediated genome editing has achieved and is reported in previous studies and address the challenges associated with it.

    Is perinatal mortality rate higher among births born following assisted reproductive technology (ART) compared to non-ART births? Overall perinatal mortality rates in ART births was higher compared to non-ART births, but gestational age-specific perinatal mortality rate of ART births was lower for very preterm and moderate to late preterm births. Births born following ART are reported to have higher risk of adverse perinatal outcomes compared to non-ART births. This population-based retrospective cohort study included 407 368 babies (391 952 non-ART and 15 416 ART)-393 491 singletons and 10 877 twins or high order multiples. All births (≥20 weeks of gestation and/or ≥400 g of birthweight) in five states and territories in Australia during the period 2007-2009 were included in the study, using National Perinatal Data Collection (NPDC). Primary outcome measures were rates of stillbirth, neonatal and perinatal deaths. Adjusted odds ratio (AOR) and 95% confidence interval (CI) were used to estimate the likelihood of perinatal death. Rates of multiple birth and low birthweight were significantly higher in ART group compared to the non-ART group (P ART births (16.5 per 1000 births, 95% CI 14.5-18.6), compared to non-ART births (11.3 per 1000 births, 95% CI 11.0-11.6) (AOR 1.45, 95% CI 1.26-1.68). However, gestational age-specific perinatal mortality rate of ART births (including both singletons and multiples) was lower for very preterm (ART births. Congenital abnormality and spontaneous preterm were the most common causes of neonatal deaths in both ART and non-ART group. Due to different cut-off limit for perinatal period in Australia, the results of this study should be interpreted with cautions for other countries. Australian definition of perinatal period commences at 20 completed weeks (140 days) of gestation and ends 27 completed days after birth which is different from the definition by World Health Organisation (commences at 22 completed weeks (154 days) of

    Although tablet systems are becoming a powerful technology, particularly useful in every application of medical imaging, to date no one has investigated the acceptance and performance of this technology in digital cytology. The specific aims of the work were (1) to design a health technology assessment (HTA) tool to assess, in terms of performance and acceptance, the introduction of tablet technologies (wearable, portable, and non portable) in the e-laboratories of cytology and (2) to test the tool in a first significant application of digital cytology. An HTA tool was proposed operating on a domain of five dimensions of investigation comprising the basic information of the product of digital cytology, the perceived subjective quality of images, the assessment of the virtual navigation on the e-slide, the assessment of the information and communication technologies features, and the diagnostic power. Six e-slides regarding studies of cervicovaginal cytology digitalized by means of an Aperio ( www.aperio.com ) scanner and uploaded onto the www.digitalslide.it Web site were used for testing the methodology on three different network connections. Three experts of cytology successfully tested the methodology on seven tablets found suitable for the study in their own standard configuration. Specific indexes furnished by the tool indicated both a high degree of performance and subjective acceptance of the investigated technology. The HTA tool thus could be useful to investigate new tablet technologies in digital cytology and furnish stakeholders with useful information that may help them make decisions involving the healthcare system. From a global point of view the study demonstrates the feasibility of using the tablet technology in digital cytology.

    The Strategic Roadmap for the Oak Ridge Reservation is a generalized planning document that identifies broad categories of issues that keep ORNL outside full compliance with the law and other legally binding agreements. Possible generic paths to compliance, issues, and the schedule for resolution of the issues one identified. The role of the Oak Ridge National Laboratory Technology Logic Diagram (TLD) is then to identify specific site issues (problems), identify specific technologies that can be brought to bear on the issues, and assess the current status and readiness of these remediation technologies within the constraints of the schedule commitment. Regulatory requirements and commitments contained in the Strategic Roadmap for the Oak Ridge Reservation are also included in the TLD as constraints to the application of immature technological solutions. Some otherwise attractive technological solutions may not be employed because they may not be deployable on the schedule enumerated in the regulatory agreements. The roadmap for ORNL includes a list of 46 comprehensive logic diagrams for WM of low-level, radioactive-mixed, hazardous, sanitary and industrial. and TRU waste. The roadmapping process gives comparisons of the installation as it exists to the way the installation should exist under full compliance. The identification of the issues is the goal of roadmapping. This allows accurate and timely formulation of activities.

    This study aimed to investigate developmental outcomes of Japanese babies born through Assisted Reproductive Technology (ART) at ages 2 and 3. The data were gathered from 1085 children in a hospital-based cohort study conducted in Japan. The children's level of development was assessed through a parent-rated questionnaire, the Kinder Infant Development Scale, which consists of nine developmental domains. We compared the development of children born through ART and those born naturally by conducting analyses of covariance. For the analyses, the effect of maternal age, family income, parental education and multiple birth were controlled for. At 24 months, no significant difference was found between children born through ART and those born naturally in development in any domain. At 36 months, a significant difference was found in development of Receptive language (F (1, 845) = 6.148, P = 0.013), Expressive language (F (1, 845) = 4.060, P = 0.044) and Language concept (F (1, 845) = 6.968, P = 0.008). For these domains, children born through ART had a significantly higher developmental age compared to children born naturally. At age 2, no significant difference was found between the children born through ART and those born naturally in nine developmental domains, although at age 3, the children born through ART showed significantly better language development than the children born naturally. © 2018 Japan Society of Obstetrics and Gynecology.

    The present study was designed to investigate the relationships between indicators of male body mass index (BMI), age, reproductive hormone levels, semen parameters, and the outcomes of assisted reproductive technology (ART). The clinical data were collected from 636 couples who underwent ART between January, 2013 and December, 2015 at the reproductive center involved in our study. Pearson's correlation or Spearman rank correlation was applied to establish the relevant correlation coefficients. The correlation between influence factors' and pregnancy outcomes was analyzed using the Logistic regression model. Analyses were conducted using SPSS software. Male BMI was found to be negatively correlated with testosterone (T) ( P ART outcome. A higher male age was also negatively connected with the outcome of clinical pregnancy. Reproductive hormones were not associated with ART outcome. Sperm concentration and female age were important factors influencing ART clinical pregnancy, while the only significant factor influencing live birth was female age. Levels of obesity-related inflammatory indicators (i.e. free fatty acid (FFA), glutathione peroxidase (GSH-Px), human inhibin-B (IHNB), interleukin-1 (IL-1), insulin-like growth factor-1 (IGF-1), and reactive oxygen species (ROS)) also varied with degrees of BMI. The present study provides information on the associations between male reproductive characteristics and the outcome of ART, which may contribute to improved strategies to help couples achieve better pregnancy outcomes. © 2017 The Author(s).

    Whether the type of culture media utilized in assisted reproductive technology has impacts on laboratory outcomes and birth weight of newborns in in-vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) was investigated. A total of 673 patients undergoing IVF/ICSI and giving birth to live singletons after fresh embryo transfer on day 3 from Jan. 1, 2010 to Dec. 31, 2012 were included. Three types of culture media were used during this period: Quinn's Advantage (QA), Single Step Medium (SSM), and Continuous Single Culture medium (CSC). Fertilization rate (FR), normal fertilization rate (NFR), cleavage rate (CR), normal cleavage rate (NCR), good-quality embryo rate (GQER) and neonatal birth weight were compared using one-way ANOVA and χ (2) tests. Multiple linear regression analysis was performed to determine the impact of culture media on laboratory outcomes and birth weight. In IVF cycles, GQER was significantly decreased in SSM medium group as compared with QA or CSC media groups (63.6% vs. 69.0% in QA; vs. 71.3% in CSC, P=0.011). In ICSI cycles, FR, NFR and CR were significantly lower in CSC medium group than in other two media groups. No significant difference was observed in neonatal birthweight among the three groups (P=0.759). Multiple linear regression analyses confirmed that the type of culture medium was correlated with FR, NFR, CR and GQER, but not with neonatal birth weight. The type of culture media had potential influences on laboratory outcomes but did not exhibit an impact on the birth weight of singletons in ART.

  19. L’incontro di Bruno Munari con la didattica attiva. I fondamenti pedagogici dei laboratori "Giocare con l’arte".

    Directory of Open Access Journals (Sweden)

    Laura Panizza

    2009-07-01

    Full Text Available Il saggio affronta il tema: quali idee pedagogiche hanno influenzato la progettazione dei laboratori "Giocare con l’arte", ideati da Bruni Munari negli anni Settanta e destinati a trasformare profondamente il modo d’intendere la didattica museale e l’educazione estetico-artistica. L’ipotesi dell’autrice è che questi laboratori riprendano alcuni principi dell’attivismo pedagogico, a cui Munari non fa però esplicito riferimento nei suoi scritti. Per questo motivo, il saggio cerca di ricostruire gli incontri più significativi che possono aver mediato l’approccio alla didattica attiva, soffermandosi in particolare sui rapporti di collaborazione intessuti da Munari con lo scrittore Gianni Rodari e con il pedagogista Giovanni Belgrano. Sia Rodari, sia Belgrano erano legati – seppure con diverse modalità – al Movimento di Cooperazione Educativa, che si proponeva di rinnovare la scuola italiana ispirandosi alla pedagogia deweyana. Attraverso la loro mediazione, Munari può essersi avvicinato all’attivismo, di cui condivideva peraltro molteplici assunti: dall’esigenza di promuovere la creatività del bambino, mediante la sperimentazione di materiali e tecniche, alla concezione dell’educatore come animatore delle attività volte alla padronanza dei saperi. In tal senso, il saggio si propone anche di mostrare la continuità esistente tra questa linea teorica e la riflessione sulla democratizzazione dell’arte intrapresa da Munari già nel 1948, con la fondazione – insieme ad altri artisti – del Movimento Arte Concreta.

    The purpose of this study was to identify science teachers' perceptions concerning the use of technology in science laboratories and identify teachers' concerns and recommendations for improving students' learning. Survey methodology with electronic delivery was used to gather data from 164 science teachers representing Texas public schools. The data confirmed that weaknesses identified in the 1990s still exist. Lack of equipment, classroom space, and technology access, as well as large numbers of students, were reported as major barriers to the implementation of technology in science laboratories. Significant differences were found based on gender, grade level, certification type, years of experience, and technology proficiency. Females, elementary teachers, traditionally trained teachers, and less experienced teachers revealed a more positive attitude toward the use of technology in science laboratories. Participants in this study preferred using science software simulations to support rather than replace traditional science laboratories. Teachers in this study recommended professional development programs that focused on strategies for a technology integrated classroom.

    Depression is associated with poor antiretroviral therapy (ART) adherence among people living with HIV/AIDS. This relationship may be moderated by an individual's social network characteristics. Our study sought to examine social network correlates of treatment adherence among HIV-positive men recruited from social service agencies throughout Los Angeles County (N = 150) to inform technology-driven social support interventions for this population. We administered egocentric social network and computer-assisted survey interviews focused on demographic characteristics, health history, depressive symptoms, and ART adherence, where adherence was assessed by the number of reasons participants missed taking their medication, if ever. Significant univariate correlates of adherence were included in a multivariable regression analysis, where the moderating effect of having a network member who reminds participants to take their HIV medication on the relationship between depression and adherence was tested. Over 60% of participants reported clinically significant depressive symptoms; this was significantly associated with lower adherence among those without someone in their social network to remind them about taking their HIV medication, even after adjusting for covariates in an ordinary least squares regression (adjusted mean difference b = -1.61, SE = 0.42, p = 0.0003). Having a network member who reminds participants to take their ART medication significantly ameliorated the negative association between depression and treatment adherence, especially for those reporting greater depressive symptoms (p = 0.0394). Additionally, participants demonstrated high rates of technology use to communicate with social network members. In order to achieve the aims of the National HIV/AIDS Strategy, innovative interventions addressing mental health to improve ART adherence are needed. Network strategies that leverage technology may be helpful for improving ART

  3. Births resulting from assisted reproductive technology: comparing birth certificate and National ART Surveillance System Data, 2011.

    This report compares data on births resulting from assisted reproductive technology (ART) procedures from 2011 birth certificates with data from the 2011 National ART Surveillance System (NASS) among the subset of jurisdictions that adopted the 2003 revised birth certificate as of January 1, 2011, with information on ART. Birth certificate data are based on 100% of births registered in 27 states and the District of Columbia. NASS data included all ART cycles initiated in 2010 or 2011 for which a live birth in 2011 was reported. The same reporting area was used for both data sources and represents 67% of all births in the United States in 2011. A ratio was computed by dividing the percentage of births resulting from ART procedures for NASS data by the percentage for birth certificate data. A ratio of 1.0 represents equivalent levels of reporting. Because this reporting area is not a random sample of births, the results are not generalizable to the United States as a whole. Overall, the percentage of births resulting from ART procedures was 2.06 times higher for NASS data (1.44%) compared with birth certificate data (0.70%). The ratio for each jurisdiction varied from 1.04 for Utah and Wisconsin to 7.50 for Florida. Higher-risk groups had more consistent reporting. between data sources [e.g., triplet or higher-order multiples (1.36) compared with singletons (2.11)]. Births resulting from ART procedures appear to be underreported on the birth certificate; however, the magnitude of underreporting varied by jurisdiction and maternal-infant health characteristics.

    Renaissance painters used a number of inorganic color materials. The development of mineralogy as a discipline opened a new discourse on mineral pigments. Agricola and other naturalists were familiar with the contemporary writings on art technology, but their focus was different. Therefore, the exchange of knowledge between these two color worlds remained selective. One possible meeting point was the Kunstkammer where the study of natural objects and materials was combined with an interest in the manual execution of a painting.

    Highlights: • This paper reviews the state of the art of wind energy conversion systems. • Different types of common wind energy conversion systems are classified and compared. • The four most popular MPPT control methods are reviewed and compared. • The latest development of wind energy conversion technologies is introduced. • Future trends of the wind energy conversion technologies are discussed. - Abstract: This paper gives a comprehensive review of the state of the art of wind energy conversion systems (WECS) and technologies, with an emphasis on wind power generator and control. First, different types of common WECSs are classified according to their features and drive train types. The WECSs are compared on the basis of the volume, weight, cost, efficiency, system reliability and fault ride through capability. The maximum power point tracking (MPPT) control, which aims to make the generator speed meet an optimum value to ensure the maximum energy yield, plays a key role in the variable speed WECSs. A comprehensive review and comparison of the four most popular MPPT control methods are carried out and improvements for each method are presented. Furthermore, the latest development of wind energy conversion technologies is introduced, such as the brushless doubly fed induction generator (BDFIG), the stator permanent magnet synchronous generators, the magnetic-geared generators, dual power flow WECS with the electrical variable transmission (EVT) machine, and direct grid-connected WECS. Finally, the future trends of the technologies are discussed

    To assess anger, as well as other negative emotions, in women who underwent assisted reproductive technology (ART) respect to women who conceived naturally, and explore the effect of anger on neonatal outcomes. We recorded personal and obstetric history of the patients, neonatal weight, Apgar score, obstetric and neonatal complications. We performed Structural Clinical Interview for DSM-SCID I and II in order to assess the DSM IV axis I and axis II, State-Trait Anger Expression Inventory 2 (STAXI-2), the Self-rating Depression Scale (SDS) and Self-rating Anxiety scale (SAS). On the STAXI-2 scale, the ART group scored higher than the natural conception group on measures of general tendency and personality disposition to get angry. Moreover, the ART group women showed quite low levels of tolerance to negative environmental feedback. Our results further suggest that trait anger provides the most meaningful contribution as predictor of weight at birth. No significant differences were found for anxiety and depression between the two groups. Our study highlights the important role of anger during pregnancy, and suggests the need for further studies on both biochemical and behavioural patterns in larger samples of women who became pregnant by ART.

    The aim of this study was to evaluate the influence of body mass index (BMI) and ultrasound-estimated visceral adipose tissue deposits on oocyte quality and pregnancy rate in women undergoing Assisted Reproductive Technology (ART) procedures. The study included 58 women who underwent ART procedures. According to their BMI, the women were divided into normal weight and overweight/obese; an ultrasound evaluation of preperitoneal fat thickness (PFT) was also performed for each patient. The oocyte quality was then assessed, and samples of follicular fluid were collected from each woman, in order to evaluate the intrafollicular concentration of reactive oxygen species (ROS) as markers of oxidative stress and pro-inflammatory cytokines (IL-1β and IL-6) as markers of chronic inflammation. A negative correlation was found between BMI (as well as PFT) and the number of retrieved oocytes (r = -0.3; p ART procedures, BMI and PFT negatively influence the number of oocytes retrieved and their quality. However, on multivariable analysis, only age, PFT and number of retrieved oocytes affect the success rate of ART procedures.

    The Department of Energy created the Office of Environmental Management (EM) to conduct a 30-year plus, multi-billion dollar program to manage the wastes and cleanup the legacy from over fifty years of nuclear material production. Across the DOE System there are thousands of sites containing millions of metric tons of buried wastes and contaminated soils and groundwater. Additionally, there are nearly 400,000 m 3 of highly radioactive wastes in underground storage tanks, over 1,400 different mixed-waste streams, and thousands of contaminated surplus facilities, some exceeding 200,000 m 2 in size. Costs to remediate all these problems have been estimated to be as much as several hundred billion dollars. The tremendous technical challenges with some of the problems and the high costs of using existing technologies has led the Department to create the Office of Technology Development (TD) to lead an aggressive, integrated national program to develop and deploy the needed advanced, cost-effective technologies. This program is developing technologies for all major cleanup steps: assessment, characterization, retrieval, treatment, final stabilization, and disposal. Work is focused on the Department's five major problem areas: High-Level Waste Tank Remediation; Contaminant Plume Containment and Remediation; Mixed Waste Characterization, Treatment, and Disposal; Contaminated Soils and Buried Wastes Facility Transitioning, Decommissioning, and Final Disposal

    2017-12-01

    Full Text Available The research and use of positioning and navigation technologies outdoors has seen a steady and exponential growth. Based on this success, there have been attempts to implement these technologies indoors, leading to numerous studies. Most of the algorithms, techniques and technologies used have been implemented outdoors. However, how they fare indoors is different altogether. Thus, several technologies have been proposed and implemented to improve positioning and navigation indoors. Among them are Infrared (IR, Ultrasound, Audible Sound, Magnetic, Optical and Vision, Radio Frequency (RF, Visible Light, Pedestrian Dead Reckoning (PDR/Inertial Navigation System (INS and Hybrid. The RF technologies include Bluetooth, Ultra-wideband (UWB, Wireless Sensor Network (WSN, Wireless Local Area Network (WLAN, Radio-Frequency Identification (RFID and Near Field Communication (NFC. In addition, positioning techniques applied in indoor positioning systems include the signal properties and positioning algorithms. The prevalent signal properties are Angle of Arrival (AOA, Time of Arrival (TOA, Time Difference of Arrival (TDOA and Received Signal Strength Indication (RSSI, while the positioning algorithms are Triangulation, Trilateration, Proximity and Scene Analysis/ Fingerprinting. This paper presents a state-of-the-art survey of indoor positioning and navigation systems and technologies, and their use in various scenarios. It analyses distinct positioning technology metrics such as accuracy, complexity, cost, privacy, scalability and usability. This paper has profound implications for future studies of positioning and navigation.

    Nowadays Research and Development activities on Solar Thermal Power Generating Systems are supported by some countries around the world. Because of their thermal nature each of these plants can be operated only with solar energy or can be hybridized (solar/fossil fuel) and also with thermal storage systems. These types of solar thermal power plants are: Central Receiver, a circular field of tracking mirrors called helisotats reflects the solar energy onto receiver mounted on top of a central tower. Parabolic Trough, use linear parabolic concentrators to reflect sunlight to a receiver along the focal line (metallic pipe). Inside the pipe solar energy is absorbed in a working fluid with temperatures up to 390 Celsius degrees, which is then piped to a central location to power a conventional steam turbine and Parabolic Dish uses a parabolic dish concentrator to focus solar energy to a receiver and a heat engine/generator, located at the focus of the dish, to generate electrical power. In this document, we present the current status of technologies. A description of market opportunities, cost and technological perspectives are also included.

    1989-08-01

    We at Sandia first became involved with developing energy technology when the nation initiated its push toward energy independence in the early 1970s. That involvement continues to be strong. In shaping Sandia's energy programs for the 1990s, we will build on our track record from the 70s and 80s, a record outlined in this publication. It contains reprints of three issues of Sandia's Lab News that were devoted to our non-nuclear energy programs. Together, they summarize the history, current activities, and future of Sandia's diverse energy concerns; hence my desire to see them in one volume. Written in the fall of 1988, the articles cover Sandia's extremely broad range of energy technologies -- coal, oil and gas, geothermal, solar thermal, photovoltaics, wind, rechargeable batteries, and combustion.

    There have been calls to restrict access to fertility treatment in women above a certain body mass index (BMI). It is important to consider public expectations before formulating policy. The study objective was to assess public opinion regarding provision of assisted reproductive technology (ART) to obese (BMI>30 kg/m(2)) women in the United States. The study was conducted through an Internet-based survey of U.S. residents ages 18-75. Multivariate odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using unconditional logistic regression to describe predictors of response based on demographic characteristics. Of the 1049 respondents, 60.7% support the use of ART in obese women. Adjusting for age and gender, the odds of support were over twice as high in participants with BMI>40 kg/m(2) as in normal-weight respondents (OR=2.87, 95% CI=1.28-6.44). Fifty-five percent of participants supported a BMI limit for access to ART. Both increasing education (p-value=0.02) and BMI (p-value=0.01) were inversely associated with support of a BMI limit. Individuals who had themselves used ART were also less likely (OR=0.27, 95% CI=0.07--0.99) to support a BMI limit. In an Internet-based survey, participants who are in favor of ART are likely to support its use among obese women. More than 50% of these respondents also support implementation of a BMI limit for access to these services.

    In recent years, new research has brought the field of electroencephalogram (EEG)-based brain–computer interfacing (BCI) out of its infancy and into a phase of relative maturity through many demonstrated prototypes such as brain-controlled wheelchairs, keyboards, and computer games. With this proof-of-concept phase in the past, the time is now ripe to focus on the development of practical BCI technologies that can be brought out of the lab and into real-world applications. In particular, we focus on the prospect of improving the lives of countless disabled individuals through a combination of BCI technology with existing assistive technologies (AT). In pursuit of more practical BCIs for use outside of the lab, in this paper, we identify four application areas where disabled individuals could greatly benefit from advancements in BCI technology, namely, “Communication and Control”, “Motor Substitution”, “Entertainment”, and “Motor Recovery”. We review the current state of the art and possible future developments, while discussing the main research issues in these four areas. In particular, we expect the most progress in the development of technologies such as hybrid BCI architectures, user–machine adaptation algorithms, the exploitation of users’ mental states for BCI reliability and confidence measures, the incorporation of principles in human–computer interaction (HCI) to improve BCI usability, and the development of novel BCI technology including better EEG devices.

    To determine whether the psychosocial risks associated with multiple births are increased as a consequence of the use of assisted reproductive technology (ART) in comparison with those not resulting from ART. Cross-sectional study. Fertility units of a university hospital and a private hospital. Parents of single children and multiples (twins and triplets) between 6 months and 4 years of age (n = 636) were divided into two groups: those who conceived through ART (n = 265) and those who conceived through non-ART (n = 371). Administration of six scales, in office or by mail. Measurement scales of material necessities, social stigma, marital satisfaction, perceived stress, depression, quality of life, and their subscales. The analysis of variance, Student's t-test, and χ(2)-test were applied. No effect was observed based on the use of ART in the psychosocial variables studied. Significant differences were obtained between the groups of single (SB) and multiple births (MB) with respect to material necessities, social stigma, marital satisfaction, depression, and quality of life. Having more than one child per birth, whether resulting from the use of ART or not, increases psychosocial risks for the parents. Assisted reproduction centers should include this information with the obstetric and neonatal risks, stressing the advantages of having one child per birth. Psychosocial risks are not increased as a result of having used ART, but the goal of avoiding the repeated use of ART does influence the desire to transfer the maximum number of embryos possible. Psychological counseling should be included before initiating ART, as well as when a multiple pregnancy is confirmed. Copyright © 2011. Published by Elsevier Inc.

    The Oak Ridge National Laboratory Technology Logic Diagram (TLD) was developed to provide a decision support tool that relates environmental restoration (ER) and waste management (WM) problems at Oak Ridge National Laboratory (ORNL) to potential technologies that can remediate these problems. The TLD consists of three fundamentally separate volumes: Vol. 1, Technology Evaluation; Vol. 2, Technology Logic Diagram; and Vol. 3, Technology Evaluation Data Sheets. Part A of Vols. 1 and 2 focuses on RA. Part B of Vols. 1 and 2 focuses on the D&D of contaminated facilities. Part C of Vols. 1 and 2 focuses on WM. Each part of Vol. 1 contains an overview of the TLD, an explanation of the problems facing the volume-specific program, a review of identified technologies, and rankings of technologies applicable to the site. Volume 2 (Pts. A, B, and C) contains the logic linkages among EM goals, environmental problems, and the various technologies that have the potential to solve these problems. Volume 3 (Pts. A, B,and C) contains the TLD data sheets. This volume provides the technology evaluation data sheets (TEDS) for ER/WM activities (D&D, RA, and WM) that are referenced by a TEDS code number in Vol. 2 of the TLD. Each of these sheets represents a single logic trace across the TLD. These sheets contain more detail than is given for the technologies in Vol. 2. The data sheets are arranged alphanumerically by the TEDS code number in the upper right comer of each sheet.

    2016-02-01

    In recent years, an ever increasing range of technology-based applications have been developed with the goal of assisting in the delivery of more effective and efficient fall prevention interventions. Whilst there have been a number of studies that have surveyed technologies for a particular sub-domain of fall prevention, there is no existing research which surveys the full spectrum of falls prevention interventions and characterises the range of technologies that have augmented this landscape. This study presents a conceptual framework and survey of the state of the art of technology-based fall prevention systems which is derived from a systematic template analysis of studies presented in contemporary research literature. The framework proposes four broad categories of fall prevention intervention system: Pre-fall prevention; Post-fall prevention; Fall injury prevention; Cross-fall prevention. Other categories include, Application type, Technology deployment platform, Information sources, Deployment environment, User interface type, and Collaborative function. After presenting the conceptual framework, a detailed survey of the state of the art is presented as a function of the proposed framework. A number of research challenges emerge as a result of surveying the research literature, which include a need for: new systems that focus on overcoming extrinsic falls risk factors; systems that support the environmental risk assessment process; systems that enable patients and practitioners to develop more collaborative relationships and engage in shared decision making during falls risk assessment and prevention activities. In response to these challenges, recommendations and future research directions are proposed to overcome each respective challenge. Copyright © 2016 The Authors. Published by Elsevier Inc.

    The state of the art in the technology of pressure vessels and piping of the primary cooling circuit of nuclear steam supply systems is discussed. Design and analysis are considered in the frame of the two types of nuclear reactor retained in France (PWR and the pool type LMFBR). Designing nuclear pressure vessels asks for some more specific Codes and Standards than for conventional vessels, and the stress analysis complementing by a direct comparison between operating loads and failure loads is a mandatory practice in France. As for pool type LMFBR, the structural problems of the nuclear vessel are essentially due to component shape, small thickness, and large stress range

  7. Using E-Learning Portfolio Technology To Support Visual Art Learning

    2009-08-01

    Full Text Available Inspired by self-directed learning (SDL theories, this paper uses learning portfolios as a reflective practice to improve student learning and develop personal responsibility, growth and autonomy in learning in a Visual Arts course. Students use PowerPoint presentations to demonstrate their concepts by creating folders that are linked to e-portfolios on the University website. This paper establishes the role of learning e-portfolios to improve teaching and learning as a model of reflection, collaboration and documentation in the making of art as a self-directed process. These portfolios link students' creative thinking to their conceptual frameworks. They also establish a process of inquiry using journals to map students' processes through their reflections and peer feedback. This practice argues that learning e-portfolios in studio art not only depends on a set of objectives whose means are justified by an agreed end but also depends on a practice that engages students' reflection about their actions while in their art- making practice. Using the principles of the maker as the intuitive and reflective practitioner, the making as the process in which the learning e-portfolios communicate the process and conceptual frameworks of learning and the eventual product, and the made as evidence of that learning in light of progress made, this paper demonstrates that learning-in-action and reflecting-in and-on-action are driven by self-direction. With technology, students bring their learning context to bear with the use of SDL. Students' use of PowerPoint program technology in making their portfolios is systematic and builds on students' competencies as this process guides students' beliefs and actions about their work that is based on theory and concepts in response to a visual culture that is Trinidad and Tobago. Students' self–directed art-making process as a self directed learning, models the process of articulated learning. Communicating about

    In recent years the transfer of old documents (books, paintings, maps etc.) from analogue to digital form has gained enormous importance. Numerous interventions are concentrated in the digitalisation of library collections, but also commercial companies like Microsoft or Google try to convert large analogue stocks such as books, paintings, etc. in digital form. Data in digital form can be much easier made accessible to a large user community, especially to the interested scientific community. The aim of the described research project is to set up a virtual research environment for interdisciplinary research focusing on the landscape of the historical Mecklenburg in the north-east of Germany. Georeferenced old maps from 1786 and 1890 covering complete Mecklenburg should be combined with current geo-information, satellite and aerial imagery to support spatio-temporal research aspects in different scales in space (regional 1:200,000 to local 1:25.000) and time (nearly 250 years in three time steps, the last 30 years also in three time slices). The Virtual Laboratory for Cultural Landscape Research (VKLandLab) is designed and developed by the Chair of Geodesy and Geoinformatics, hosted at the Computing Centre (ITMZ) and linked to the Digital Library (UB) at Rostock University. VKLandLab includes new developments such as wikis, blogs, data tagging, etc. and proven components already integrated in various data-related infrastructures such as InternetGIS, data repositories and authentication structures. The focus is to build a data-related infrastructure and a work platform that supports students as well as researchers from different disciplines in their research in space and time.

    Neven, Sylvie

    2016-01-01

    In the Middle Ages and the premodern period knowledge of alchemical practices and materials was transmitted via collections of recipes often grouped concomitantly with art-technological instructions. In both alchemy and chemical technology particular importance is placed on artisanal and craft practices. Both are concerned with the description of colours. Both require procedures involving precise and specifically defined actions, prescriptions and ingredients. Assuming that alchemical and artistic texts have the same textual format, this raises the question: were they produced, diffused and read by the same people? This paper investigates the authorship and the context of production behind a sample of German alchemical manuscripts dating from the fourteenth to the sixteenth century. It scrutinizes their process of production, compilation and dissemination. This paper also sheds light on the various types of marginalia, and correlates them with their diverse functions. It thus delivers significant information about the readers and users of these manuscripts.

    A number of studies have investigated the relationship between psychological factors such as stress and distress (measured as anxiety and depression) and outcomes of assisted reproductive technology (ART). The results, however, are inconsistent, and the strength of any associations remains to be clarified. We conducted a systematic review and meta-analysis of the results of studies reporting on the associations between stress, anxiety, and depression and ART outcomes. Prospective studies reporting data on associations between stress or distress in female patients and ART outcome were identified and evaluated by two independent researchers according to an a priori developed codebook. Authors were contacted in cases of insufficient data reporting. Stress was defined as perceived stress, work-related stress, minor life events or major life events, and distress was defined as anxiety or depression. A total of 31 prospective studies were included. Small, statistically significant, pooled effect sizes were found for stress [ESr, effect size correlation) = -0.08; P = 0.02, 95% confidence interval (CI): -0.15, -0.01], trait anxiety (ESr = -0.14; P = 0.02, 95% CI: -0.25, -0.03) and state anxiety (ESr = -0.10, P = 0.03, 95% CI: -0.19, -0.01), indicating negative associations with clinical pregnancy rates. A non-significant trend (Esr = -0.11, P = 0.06) was found for an association between depression and clinical pregnancy. For serum pregnancy tests and live birth rates, associations between trait anxiety or state anxiety were not significant. The fail safe number did not exceed the suggested criterion in any analyses, between-study heterogeneity was considerable and the mean age, mean duration of infertility and percentage of first time ART attenders in the study samples were found to moderate several of the associations. Small but significant associations were found between stress and distress and reduced pregnancy chances with ART. However, there were a limited number of

    Full Text Available This paper presents a best-practice model for the redesign of virtual learning environments (VLEs within creative arts to augment blended learning. In considering a blended learning best-practice model, three factors should be considered: the conscious and active human intervention, good learning design and pedagogical input, and the sensitive handling of the process by trained professionals. This study is based on a comprehensive VLE content analysis conducted across two academic schools within the creative arts at one Post-92 higher education (HE institution. It was found that four main barriers affect the use of the VLE within creative arts: lack of flexibility in relation to navigation and interface, time in developing resources, competency level of tutors (confidence in developing online resources balanced against other flexible open resources and factors affecting the engagement of ‘digital residents’. The experimental approach adopted in this study involved a partnership between the learning technology advisor and academic staff, which resulted in a VLE best-practice model that focused directly on improving aesthetics and navigation. The approach adopted in this study allowed a purposive sample of academic staff to engage as participants, stepping back cognitively from their routine practices in relation to their use of the VLE and questioning approaches to how they embed the VLE to support teaching and learning. The model presented in this paper identified a potential solution to overcome the challenges of integrating the VLE within creative arts. The findings of this study demonstrate positive impact on staff and student experience and provide a sustainable model of good practice for the redesign of the VLE within creative disciplines.

    Leveraging technology to enhance antiretroviral therapy (ART) adherence, and factors associated with it, has tremendous appeal as a low-cost, generalizable strategy to offer high-quality adherence support given an increasingly limited workforce. As the numbers of individuals living with HIV entering care and initiating ART are expected to increase substantially worldwide in the next decade, capacity to support ART adherence is needed and use of computers, internet, and mobile phones has the potential to offer those efficiencies-provided they are effective. This review summarizes recent advances in the evidence base for technology-driven, technology-delivered, or technology-enhanced ART adherence intervention approaches. A PubMed search limited to January 2013 through July 2015 identified 13 qualifying studies evaluating computer-delivered interventions, internet approaches, mobile phone technologies, and electronic dose monitoring with triggered messaging and data-informed counseling. Considerable support for each area has emerged, with the majority of studies reviewed demonstrating significant effects on ART adherence and clinical outcomes. Gaps are identified and recommendations offered.

    1994-01-01

    To address the problem of characterizing uranium-contaminated surface soil at federal facilities, the Department of Energy has the development of four uranium field screening technologies, under the direction of the Uranium-in-Soils Integrated Demonstration (USID) Program. These four technologies include: a long-range alpha detector a beta scintillation detector, an in situ gamma detector, and a mobile laser ablation-inductively coupled plasma/atomic emission spectrometry (LA-ICP/AES) laboratory. As part of the performance assessment for these field screening technologies, cost estimates for the development and operation of each technology were created. A cost study was conducted to compare three of the USID field screening technologies to the use of traditional field surveying equipment to adequately characterize surface soils of a one-acre site. The results indicate that the use of traditional equipment costs more than the in situ gamma detector, but less than the beta scintillation detector and LRAD. The use of traditional field surveying equipment results in cost savings of 4% and 34% over the use of the beta scintillation and LRAD technologies, respectively. A study of single-point surface soil sampling and laboratory analysis costs was also conducted. Operational costs of the mobile LA-ICP/AES laboratory were compared with operational costs of traditional sampling and analysis, which consists of collecting soil samples and conducting analysis in a radiochemical laboratory. The cost study indicates that the use of the mobile LA-ICP/AES laboratory results in cost savings of 23% and 40% over traditional field sampling and laboratory analysis conducted by characterization groups at two DOE facilities

    Oak Ridge National Laboratory has developed and is continuing to refine a method of immobilizing low-level radioactive liquid wastes by mixing them with cementitious dry-solid blends. A quality assurance program is vital to the project because Nuclear Regulatory Commission (NRC), Environmental Protection Agency (EPA) and state environmental regulations must be demonstrably met (the work must be defensible in a court of law). The end result of quality assurance (QA) is, by definition, a product of demonstrable quality. In the laboratory, this entails traceability, repeatability, and credibility. This paper describes the application of QA in grout technology development at Oak Ridge National Laboratory

    Ayers, C.W.

    2001-01-01

    The Power Electronics and Electric Machinery Research Center (PEEMRC) of Oak Ridge National Laboratory (ORNL) has for many years been developing technologies for power converters for motor drives and many other applications. Some of the research goals are to improve efficiency and reduce audible and electromagnetic interference noise generation for inverters and the driven loads. The converters are being required to produce more power with reduced weight and volume, which requires improvements in heat removal from the electronics, as well as improved circuit designs that have fewer electrical losses. PEEMRC has recently developed and patented a soft-switching inverter topology called an Auxiliary Resonant Tank (ART), and this design has been tested and proven at ORNL using a 10-kW laboratory prototype. The objective of this project was to develop, test, and install the ART inverter technology in an electric transit bus with the final goal of evaluating performance of the ORNL inverter under field conditions in a vehicle. A scaled-up inverter with the capacity to drive a 22-e bus was built based on the 10-kW ORNL laboratory prototype ART soft-switching inverter. Most (if not all) commercially available inverters for traction drive and other applications use hard-switching inverters. A Cooperative Research and Development Agreement was established with the Chattanooga Area Regional Transit Authority (CARTA), the Electric Transit Vehicle Institute (ETVI), and Advanced Vehicle Systems (AVS), all of Chattanooga, along with ORNL. CARTA, which maintains and operates the public transit system in Chattanooga, provided an area for testing the vehicle alongside other similar vehicles in the normal operating environment. ETVI offers capabilities in standardized testing and reporting and also provides exposure in the electric transit vehicle arena for ORNL's technologies. The third Chattanooga partner, (AVS) manufactures all-electric and hybrid electric transit buses using

    Rome Laboratory, one of the United States Air Force's four Super Laboratories, has been designated by the National Institute of Justice (NIJ) to be its National Law Enforcement and Corrections Technology Center for the Northeast (NLECTC-NE). A Department of Defense leader in research and development (R&D) in speech and audio processing for over 25 years, Rome Laboratory's main thrust in these R&D areas has focused on developing technology to improve the collection, handling, identification and intelligibility of communication signals. Rome Laboratory speech and audio technology is unique and particularly appropriate for application to law enforcement requirements because it addresses the military need for time critical decisions and actions, operating within noisy environments, and use by uncooperative speakers in tactical, real-time applications. Speech enhancement and speaker recognition are the primary technologies discussed in this paper. Automatic language and dialect identification, automatic gisting, spoken language translation, co-channel speaker separation and audio manipulation technologies are briefly discussed.

    At the W. M. Keck Center for Active Visualization in Earth Sciences (KeckCAVES), a group of geoscientists and computer scientists collaborate to develop and use of interactive, immersive, 3D visualization technology to view, manipulate, and interpret data for scientific research. The visual impact of immersion in a CAVE environment can be extremely compelling, and from the outset KeckCAVES scientists have collaborated with artists to bring this technology to creative works, including theater and dance performance, installations, and gamification. The first full-fledged collaboration designed and produced a performance called "Collapse: Suddenly falling down", choreographed by Della Davidson, which investigated the human and cultural response to natural and man-made disasters. Scientific data (lidar scans of disaster sites, such as landslides and mine collapses) were fully integrated into the performance by the Sideshow Physical Theatre. This presentation will discuss both the technological and creative characteristics of, and lessons learned from the collaboration. Many parallels between the artistic and scientific process emerged. We observed that both artists and scientists set out to investigate a topic, solve a problem, or answer a question. Refining that question or problem is an essential part of both the creative and scientific workflow. Both artists and scientists seek understanding (in this case understanding of natural disasters). Differences also emerged; the group noted that the scientists sought clarity (including but not limited to quantitative measurements) as a means to understanding, while the artists embraced ambiguity, also as a means to understanding. Subsequent art-science-technology collaborations have responded to evolving technology for visualization and include gamification as a means to explore data, and use of augmented reality for informal learning in museum settings.

    Building on the work that was started two decades ago, Jacobs Space Operations Group has utilized state of the art PTI technologies to assess the current condition of the assets they manage under the Test and Operations Support Contract (TOSC). Specifically, the Asset Management department leveraged the benefits of ultrasound technology to quantify a motor issue in the Liquid Oxygen Storage Area, and troubleshoot the sources prior to loading the tank to perform Verification and Validation (VV) activities. This technology was efficient, easy to implement, and provided system engineers with data on a possible source of the problem. In situations where legacy motors are exhibiting unexpected noises, it may seem easier to remove and refurbish the motor and replace the bearings because that solution resolves most of the common causes of the noise. However, that solution would have involved additional spending and may not have solved issues stemming from the foundation, if those existed. By utilizing the ultrasound equipment provided by UE Systems, the sound profiles allowed Jacobs TOSC team to determine that the issue resembled a faulty bearing. After replacing the bearing, the unexpected noise ceased.

    Health-related information collected in psychological laboratories may not be representative of people's everyday health. For at least 70 years, there has been a call for methods that sample experiences from everyday environments and circumstances. New technologies, including cell phones, sensors, and monitors, now make it possible to collect information outside of the laboratory in environments representative of everyday life. We review the role of mobile technologies in the assessment of health-related behaviors, physiological responses, and self-reports. Ecological momentary assessment offers a wide range of new opportunities for ambulatory assessment and evaluation. The value of mobile technologies for interventions to improve health is less well established. Among 21 randomized clinical trials evaluating interventions that used mobile technologies, more than half failed to document significant improvements on health outcomes or health risk factors. Theoretical and practical issues for future research are discussed.

    The quest for small drug-like compounds that selectively inhibit the function of biological targets has always been a major focus in the pharmaceutical industry and in academia as well. High-throughput screening of compound libraries requires time, cost and resources. Therefore, the use of alternative methods is necessary for facilitating lead discovery. Computational techniques that dock small molecules into macromolecular targets and predict the affinity and activity of the small molecule are widely used in drug design and discovery, and have become an integral part of the industrial and academic research. In this review, we present an overview of some state-of-the-art technologies in modern drug design that have been developed for expediting the search for novel drug candidates.

  2. State-of-the-art remote sensing geospatial technologies in support of transportation monitoring and management

    Science.gov (United States)

    Paska, Eva Petra

    The widespread use of digital technologies, combined with rapid sensor advancements resulted in a paradigm shift in geospatial technologies the end of the last millennium. The improved performance provided by the state-of-the-art airborne remote sensing technology created opportunities for new applications that require high spatial and temporal resolution data. Transportation activities represent a major segment of the economy in industrialized nations. As such both the transportation infrastructure and traffic must be carefully monitored and planned. Engineering scale topographic mapping has been a long-time geospatial data user, but the high resolution geospatial data could also be considered for vehicle extraction and velocity estimation to support traffic flow analysis. The objective of this dissertation is to provide an assessment on what state-of-the-art remote sensing technologies can offer in both areas: first, to further improve the accuracy and reliability of topographic, in particular, roadway corridor mapping systems, and second, to assess the feasibility of extracting primary data to support traffic flow computation. The discussion is concerned with airborne LiDAR (Light Detection And Ranging) and digital camera systems, supported by direct georeferencing. The review of the state-of-the-art remote sensing technologies is dedicated to address the special requirements of the two transportation applications of airborne remotely sensed data. The performance characteristics of the geospatial sensors and the overall error budget are discussed. The error analysis part is focused on the overall achievable point positioning accuracy performance of directly georeferenced remote sensing systems. The QA/QC (Quality Assurance/Quality Control) process is a challenge for any airborne direct georeferencing-based remote sensing system. A new method to support QA/QC is introduced that uses the road pavement markings to improve both sensor data accuracy as well as the

    Superconductivity is a physical effect wherein the electrical resistivity disappears at cryogenic temperatures. Superconductivity has the advantage of following large current densities and high magnetic fields, which are stable and homogeneous. There are many applications of superconductivity which take advantage of these merits. It is of special importance to apply superconductors to alternative energy and energy saving technology. This paper presents briefly some of the research and development efforts to apply superconductivity to energy technology in the Electrotechnical Laboratory

    2017-10-01

    This study aims to evaluate the environmental impacts and benefits of state-of-the-art technologies for proper e-waste handling using Jordan as a case study. Life Cycle Assessment (LCA) was employed to evaluate five advanced management systems represent state-of-the-art treatment technologies, including sanitary landfilling; proper recycling of metals, materials, and precious metals (PMs); and incineration of plastic and the hazardous portion of printed circuit boards (PCBs). Six e-waste products that contribute the most to the e-waste in Jordan were included in the assessment of each scenario, which resulted in 30 total cases of e-waste management. The findings indicated that landfills for the entire components of the e-waste stream are the worst option and should be avoided. The most promising e-waste management scenario features integrated e-waste processes based on the concept of Integrated Waste Management (IWM), including recycling materials such as non-PMs and PMs, incinerating plastic and the hazardous content of PCBs using the energy recovered from incineration, and using sanitary landfills of residues. For this scenario, the best environmental performance was obtained for the treatment of mobile phones. Incineration of the portion of hazardous waste using energy recovery is an option that deserves attention. Because scenario implementation depends on more than just the environmental benefits (e.g., economic cost and technical aspects), the study proposes a systematic approach founded on the IWM concept for e-waste management scenario selection.

    2016-02-01

    Full Text Available Objective: We present first-phase results of a performing arts public health intervention, ‘Singing and Dancing for Health,’ aiming to promote healthier behaviors in Ghana’s impoverished Northern Region. We hypothesize that live music and dance drama provide a powerful technology to overcome barriers such as illiteracy, lack of adequate media access, inadequate health resources, and entrenched sociocultural attitudes. Our research objective is to evaluate this claim. Methods: In this first phase, we evaluated the effectiveness of arts interventions in improving knowledge and behaviors associated with reduced incidence of malaria and cholera, focusing on basic information and simple practices, such as proper hand washing. Working with the Youth Home Cultural Group, we codeveloped two ‘dance dramas’ delivering health messages through dialog, lyrics, and drama, using music and dance to attract spectators, focus attention, infuse emotion, and socialize impact. We also designed knowledge, attitude, and behavior surveys as measurement instruments. Using purposive sampling, we selected three contrasting test villages in the vicinity, contrasting in size and demographics. With cooperation of chiefs, elders, elected officials, and Ghana Health Service officers, we conducted a baseline survey in each village. Next, we performed the interventions, and subsequently conducted follow-up surveys. Using a more qualitative approach, we also tracked a select subgroup, conducted focus group studies, and collected testimonials. Surveys were coded and data were analyzed by Epi Info. Results: Both quantitative and qualitative methods indicated that those who attended the dance drama performances were likelier than those who did not attend to list the causal, preventive, and transmission factors of malaria and cholera. Also, the same attendees were likelier than nonattendees to list some activities they do to prevent malaria, cholera, and other sanitation

    Full Text Available The importance of digitality in Media Art theories consolidated the aesthetic of dematerialization, as it shifted the value of materiality in this field. However, the advent of new forms of technological art, such as Bio Art, which uses laboratory technologies in an aesthetic way to manipulate life, demonstrates the crisis of this paradigm and the trend of rematerialization. This paper investigates the role of materiality, even in the more dematerialized realms of Media Art: the digital technologies. We focus on two art forms that combine new technologies and life sciences: Artificial life, which involves the intangible features of Media Art, and Bio Art, which interprets materiality in a radical manner, by choosing life as the raw material for artistic creation.

    The importance of innovative science education for social science and humanities students is often under-appreciated by science departments, because these students typically do not take science courses beyond general education requirements, nor do they contribute to faculty research programs. However, these students are vitally important in society—for example as business leaders or consultants, and especially as voters. In these roles, they will be confronted with decisions related to science in their professional and personal lives. The Council on Science and Technology at Princeton University aims to fill this education gap by developing and supporting innovative programs that bring science to cross-disciplinary audiences. One of our most fruitful collaborations has been with the Princeton University Art Museum, which has an encyclopedic collection of over 92,000 works of art, ranging from antiquity to the contemporary. Our work includes 1) bringing introductory environmental science courses to the Museum to explore how original works of art of different ages can serve as paleo-environmental proxies, thereby providing a means for discussing broader concepts in development of proxies and validation of reconstructions; 2) sponsoring a panel aimed at the general public and composed of science faculty and art historians who discussed the scientific and art historical contexts behind Albert Bierstadt's Mount Adams, Washington, 1875 (oil on canvas, gift of Mrs. Jacob N. Beam, accession number y1940-430), including the landscape's subjects, materials, technique, and style; and 3) collaborating on an installation of photographs relevant to a freshman GIS course, with an essay about the artwork written by the students. This first-hand study of works of art encourages critical thinking and an empathetic approach to different historical periods and cultures, as well as to the environment. Our collaboration additionally provides an opportunity to engage more students in

    Since its initiation, the System-wide Safety Assurance Technologies (SSAT) Project has been focused on developing multidisciplinary tools and techniques that are verified and validated to ensure prevention of loss of property and life in NextGen and enable proactive risk management through predictive methods. To this end, four technical challenges have been listed to help realize the goals of SSAT, namely (i) assurance of flight critical systems, (ii) discovery of precursors to safety incidents, (iii) assuring safe human-systems integration, and (iv) prognostic algorithm design for safety assurance. The objective of this report is to provide an extensive survey of SSAT-related research accomplishments by researchers within and outside NASA to get an understanding of what the state-of-the-art is for technologies enabling each of the four technical challenges. We hope that this report will serve as a good resource for anyone interested in gaining an understanding of the SSAT technical challenges, and also be useful in the future for project planning and resource allocation for related research.

  19. Silicon solar cell technology state of the art and a proposed double sided cell

    Seddik, M.M.

    1987-08-01

    A review of the silicon technology state of the art is given. It had been found that single crystal silicon efficiency was limitd to ≥ 20%. The reason was identified to be due to the recombination current loss mechanisms. However, use of new technologies such as back-surface field, surface passivation, double anti-reflection coatings and back-surface illumination demonstrated to achieve higher efficiencies. Experiments were carried out to evaluate the effect of back surfaces illumination on the cell efficiency enhancement. It was found that for single cell, back-surface illumination contribute a 12% increase in efficiency whereas for double cell illumination (back-to-back cells) the improvement was 59% increase in efficiency. A V-shaped flat mirror reflector with optimum angle of 45 deg. to the plane of the cell from both sides achieved the ultimate efficiency performance. Finally, a proposed high current - high efficiency solar cell called ''Double Drift'' - Double Sided Illumination Cell'' was presented. The new structures were in the form of n + pn + or p + np + double junctions. The expected efficiency ranges 50-60% with proper material design, double anti-reflection coatings and V-shaped irregular plane mirror reflector illumination. (author). 43 refs, 4 figs, 7 tabs

  20. State of the art and review on the treatment technologies of water reverse osmosis concentrates.

    Pérez-González, A; Urtiaga, A M; Ibáñez, R; Ortiz, I

    2012-02-01

    The growing demand for fresh water is partially satisfied by desalination plants that increasingly use membrane technologies and among them reverse osmosis to produce purified water. Operating with water recoveries from 35% to 85% RO plants generate huge volumes of concentrates containing all the retained compounds that are commonly discharged to water bodies and constitute a potentially serious threat to marine ecosystems; therefore there is an urgent need for environmentally friendly management options of RO brines. This paper gives an overview on the potential treatments to overcome the environmental problems associated to the direct discharge of RO concentrates. The treatment options have been classified according to the source of RO concentrates and the maturity of the technologies. For the sake of clarity three different sources of RO concentrates are differentiated i) desalination plants, ii) tertiary processes in WWTP, and iii) mining industries. Starting with traditional treatments such as evaporation and crystallization other technologies that have emerged in last years to reduce the volume of the concentrate before disposal and with the objective of achieving zero liquid discharge and recovery of valuable compounds from these effluents are also reviewed. Most of these emerging technologies have been developed at laboratory or pilot plant scale (see Table 1). With regard to RO concentrates from WWTP, the manuscript addresses recent studies that are mainly focused on reducing the organic pollutant load through the application of innovative advanced oxidation technologies. Finally, works that report the treatment of RO concentrates from industrial sources are analyzed as well. Copyright © 2011 Elsevier Ltd. All rights reserved.

  1. Anti-Mullerian hormone (AMH) as a predictive marker in assisted reproductive technology (ART).

    In women, anti-Müllerian hormone (AMH) levels may represent the ovarian follicular pool and could be a useful marker of ovarian reserve. The clinical application of AMH measurement has been proposed in the prediction of quantitative and qualitative aspects in assisted reproductive technologies (ART). In men AMH is secreted in both the serum and seminal fluid. Its measurement may be useful in clinical evaluation of the infertile male. The PubMed database was systematically searched for studies published until the end of January 2009, search criteria relevant to AMH, ovarian reserve, ovarian response to gonadotrophin stimulation, spermatogenesis and azoospermia were used. AMH seems to be a better marker in predicting ovarian response to controlled ovarian stimulation than age of the patient, FSH, estradiol and inhibin B. A similar performance for AMH and antral follicular count has been reported. In clinical practice, AMH measurement may be useful in the prediction of poor response and cycle cancellation and also of hyper-response and ovarian hyperstimulation syndrome. In the male, the wide overlap of AMH values between controls and infertile men precludes this hormone from being a useful marker of spermatogenesis. As AMH may permit the identification of both the extremes of ovarian stimulation, a possible role for its measurement may be in the individualization of treatment strategies in order to reduce the clinical risk of ART along with optimized treatment burden. It is fundamental to clarify the cost/benefit of its use in ovarian reserve testing. Regarding the role of AMH in the evaluation of infertile men, AMH as single marker of spermatogenesis does not seem to reach a satisfactory clinical utility.

  2. The advance of technology as a prelude to the laboratory of the twenty-first century.

    Woo, J; Henry, J B

    1994-09-01

    Technological changes in the clinical laboratory are usually driven by the goal of patient care optimization. In the last decade, the trend appeared to be directed at clinical laboratory decentralization. A new generation of analytical instruments, the biosensors, is redirecting laboratory testing closer to the patient, at the bedside, in the physician's office, and by the patient at home. These miniaturized biosensors are easy to operate, require small specimen size, and provide reliable results with rapid TAT. Thus far, bedside testing using biosensor technology appears to offer unique opportunities for earlier availability of clinical laboratory data, decision making, and more specific diagnosis, and faster and more frequent monitoring; these may translate into improved patient care and reduced hospital costs. It is likely that this trend will continue into the twenty-first century. Electrochemical sensors (e.g., for electrolytes, glucose, urea, and hematocrit) and pulse oximetry, having gained clinical acceptance, will probably be the leading instrumentation for bedside testing. Continuous monitoring either by near-infrared sensing technology or with an implantable sensor is valuable in the care of the critically ill patient. Acceptance for clinical use will depend on complete data integration and a favorable cost-benefit ratio.

    1994-12-01

    The Oak Ridge National Laboratory (ORNL) Gunite Tank Sludge Mobilization Technology Study was initiated to support the Gunite Tank Treatability Study effort. The technology study surveyed the methods and technologies available for tank cleaning and sludge mobilization in a radioactive environment. Technologies were identified and considered for applicability to the Gunite and Associated Tanks (GAAT) problems. These were then either accepted for further study or rejected as not applicable. Technologies deemed applicable to the GAAT sludge removal project were grouped for evaluation according to (1) deployment method, (2) types of remotely operated end effector equipment applicable to removal of sludge, (3) methods for removing wastes from the tanks, and (4) methods for concrete removal. There were three major groups of deployment technologies: ''past practice'' technologies, mechanical arm-based technologies, and vehicle-based technologies. The different technologies were then combined into logical sequences of deployment platform, problem, end effector, conveyance, post-removal treatment required (if any), and disposition of the waste. Many waste removal options are available, but the best technology in one set of circumstances at one site might not be the best type to use at a different site. No single technology is capable of treating the entire spectrum of wastes that will be encountered in GAAT. None of the systems used in other industries appears to be suitable, primarily because of the nature of the sludges in the GAAT Operable Unit (OU), their radiation levels, and tank geometries. Other commercial technologies were investigated but rejected because the authors did not believe them to be applicable

  8. Incorporating spectroscopy and measurement technology into the high school chemistry laboratory

    Science.gov (United States)

    Harbert, Emily Ann

    Science and technology are becoming increasingly important in maintaining a healthy economy at home and a competitive edge on the world stage, though that is just one facet affected by inadequate science education in the United States. Engaging students in the pursuit of knowledge and giving them the skills to think critically are paramount. One small way to assist in achieving these goals is to increase the quality and variety of technology-rich activities conducted in high school classrooms. Incorporating more laboratory measurement technology into high schools may incite more student interest in the processes and practices of science and may allow students to learn to think more critically about their data and what it represents. The first objective of the work described herein was to determine what measurement technology is being used in schools and to what extent, as well as to determine other teacher needs and preferences. Second, the objective was to develop a new program to provide incoming freshmen (or rising seniors) with measurement technology training they did not receive in high school, and expose them to new research and career opportunities in science. The final objective was to create a technology-rich classroom laboratory activity for use in high schools.

    1997-06-01

    Over the past decade, numerous companies have been formed to commercialize research results from leading U.S. academic and research institutions. Emerging small businesses in areas such as Silicon Valley, Boston`s Route 128 corridor, and North Carolina`s Research Triangle have been especially effective in moving promising technologies from the laboratory bench to the commercial marketplace--creating new jobs and economic expansion in the process. Unfortunately, many of the U.S. national laboratories have not been major participants in this technology/commercialization activity, a result of a wide variety of factors which, until recently, acted against successful commercialization. This {open_quotes}commercialization gap{close_quotes} exists partly due to a lack, within Los Alamos in particular and the DOE in general, of in-depth expertise and experience in such business areas as new business development, securities regulation, market research and the determination of commercial potential, the identification of entrepreneurial management, marketing and distribution, and venture capital sources. The immediate consequence of these factors is the disappointingly small number of start-up companies based on technologies from Los Alamos National Laboratory that have been attempted, the modest financial return Los Alamos has received from these start-ups, and the lack of significant national recognition that Los Alamos has received for creating and commercializing these technologies.

    To determine the prevalence rate of women with a diagnosis of schizophrenia or related psychotic disorder in assisted reproductive technology (ART) treatment and to study these women's fertility treatment outcome in comparison to women with no psychotic disorders. We used a national register-based cohort of 42,915 Danish women in ART treatment from 1.1.1994 to 30.9.2009. All women with a diagnosis of schizophrenia or related psychotic disorders before, during or after their ART treatment were identified by individual-level linkage of nationwide registers of ART treatment, psychiatric admission, birth and socio-demographic status. The comparison group (N=42,671) consisted of all women in the study cohort never diagnosed with psychotic disorders. Conventional descriptive methods were used for the statistical analyses. Two hundred and forty-four (0.6%) women in the study cohort received a diagnosis of psychotic disorder before (N=135-55.3%), during (N=7-2.9%) or after (N=102-41.8%) ART treatment. The mean time from last diagnosis of psychotic disorder to their first ART treatment in the 135 women with a psychiatric diagnosis prior to their first ART treatment was 7.1 ± 5.6 years (25-75% percentile: ±2.8-10.4 years). The most frequent diagnoses were acute and transient psychotic disorder. Women with a diagnosis of schizophrenia or related psychotic disorder before their first ART treatment had a lower ART treatment success rate as significantly fewer women obtained a live birth (40.0% vs. 51.9%, PART treatment have a lower fertility treatment success rate compared to women without psychotic disorder. Women with a psychotic disorder achieving delivery show similar obstetric outcomes to women with no psychotic disorder. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    The Idaho National Engineering Laboratory (INEL) Technology Logic Diagram (TLD) was developed to provide a decision support tool that relates Environmental Restoration (ER) and Waste Management (WM) problems at the INEL to potential technologies that can remediate these problems. The TLD identifies the research, development, demonstration, testing, and evaluation needed to develop these technologies to a state that allows technology transfer and application to an environmental restoration need. It is essential that follow-on engineering and system studies be conducted to build on the output of this project. These studies will begin by selecting the most promising technologies identified in this TLD and finding an optimum mix of technologies that will provide a socially acceptable balance between cost and risk to meet the site windows of opportunity. The TLD consists of three separate volumes: Volume I includes the purpose and scope of the TLD, a brief history of the INEL Waste Area Groups, and environmental problems they represent. A description of the TLD, definitions of terms, a description of the technology evaluation process, and a summary of each subelement, is presented. Volume II (this volume) describes the overall layout and development of the TLD in logic diagram format. This section addresses the environmental restoration of contaminated INEL sites. Specific INEL problem areas/contaminants are identified along with technology solutions, the status of the technologies, precise science and technology needs, and implementation requirements. Volume III provides the Technology Evaluation Data Sheets (TEDS) for Environmental Restoration and Waste Management (EM) activities that are referenced by a TEDS codenumber in Volume II. Each of these sheets represents a single logic trace across the TLD. These sheets contain more detail than provided for technologies in Volume II

    The main objective of the present R and D on breeder blanket is the development of test blanket modules (TBMs) to be installed and tested in International Thermonuclear Experimental Reactor (ITER). In the program of the blanket development, a blanket module test in the ITER is scheduled from the beginning of the ITER operation, and the performance test of TBM in ITER is the most important milestone for the development of the DEMO blanket. The fabrication of TBMs has been required to test the basic performance of the DEMO blanket, i.e., tritium production/recovery, high-grade heat generation and radiation shielding. Therefore, the integration of the TBM systems into ITER has been investigated with the aim to check the safety, reliability and compatibility under nuclear fusion state. For this reason, in the Test Blanket Working Group (TBWG) as an activity of the International Energy Association (IEA), a variety of ITER TBMs have been proposed and investigated by each party: helium-cooled ceramic (WSG-1), helium-cooled LiPb (WSG-2), water-cooled ceramic (WSG-3), self-cooled lithium (WSG-4) and self-cooled molten salt (WSG-5) blanket systems. Because we are still deficient in investigation of TBM development, the need of development became pressing.

    Full Text Available Methods: The present report attempts to illustrate the positive impact on the microbiological quality of dialysis patients over a 15-year period through the progressive implementation of state-of-the-art technological strategies and the optimization of microbiological surveillance procedures in five dialysis units in Sardinia. Results: Following on better microbiological, quality controls of dialysis water and improvement of procedures and equipment, a drastic improvement of microbiological water quality was observed in a total of 945 samples. The main aim was to introduce the use of microbiological culture methods as recommended by the most important guidelines. The microbiological results obtained have led to a progressive refining of controls and introduction of new materials and equipment, including two-stage osmosis and piping distribution rings featuring a greater capacity to prevent biofilm adhesion. The actions undertaken have resulted in unexpected quality improvements. Conclusions: Dialysis water should be viewed by the nephrologist as a medicinal product exerting a demonstrable positive impact on microinflammation in dialysis patients. A synergic effort between nephrologists and microbiologists undoubtedly constitutes the most effective means of preventing dialysis infections.

    Full Text Available We discuss the problem of people retrieval by means of composite pictures constructed according to descriptive portrait. An overview of the problem state-of-the-art is provided beginning from the basic concepts and terminology to a modern technology for composite picture creation, real-world scenarios and search results. The development history of systems for forming composite portraits (photo robots and sketches and the ideas implemented in these systems are provided. The problem of automatic comparison of composite pictures with the original ones is discussed, and the reasons for unattainability of stable retrieval of originals by a composite picture in real-world scenarios are revealed. Requirements to composite pictures databases in addition to the existing benchmark databases of facial images and also methods for implementation of such databases are formulated. Approaches for generation of sketches population from an initial one that increase effectiveness of identikit-based photo image retrieval systems are proposed. The method of similarity index increasing in the couple identikit-photograph based on computation of an average identikit from the created population is provided. It is shown that such composite pictures are more similar to original portraits and their use in the discussed search problem can lead to good results. Thus the created identikits meet the requirements of the truthful scenario as take into account the possibility of incomplete information in descriptions. Results of experiments on CUHK Face Sketch and CUHK Face Sketch FERET databases and also open access identikits and corresponding photos are discussed.

    On February 14, 2002, President Bush announced the Clear Skies Initiative, a legislative proposal to control the emissions of nitrogen oxides (NO{sub x}), sulfur dioxide (SO{sub 2}), and mercury from power plants. In response to this initiative, the National Energy Technology Laboratory organized a Combustion Technology University Alliance and hosted a Solid Fuel Combustion Technology Alliance Workshop. The workshop identified multi-pollutant control; improved sorbents and catalysts; mercury monitoring and capture; and improved understanding of the underlying reaction chemistry occurring during combustion as the most pressing research needs related to controlling environmental emissions from fossil-fueled power plants. The Environmental Control Technology Laboratory will help meet these challenges and offer solutions for problems associated with emissions from fossil-fueled power plants. The goal of this project was to develop the capability and technology database needed to support municipal, regional, and national electric power generating facilities to improve the efficiency of operation and solve operational and environmental problems. In order to effectively provide the scientific data and the methodologies required to address these issues, the project included the following aspects: (1) Establishing an Environmental Control Technology Laboratory using a laboratory-scale, simulated fluidized-bed combustion (FBC) system; (2) Designing, constructing, and operating a bench-scale (0.6 MW{sub th}), circulating fluidized-bed combustion (CFBC) system as the main component of the Environmental Control Technology Laboratory; (3) Developing a combustion technology for co-firing municipal solid waste (MSW), agricultural waste, and refuse-derived fuel (RDF) with high sulfur coals; (4) Developing a control strategy for gaseous emissions, including NO{sub x}, SO{sub 2}, organic compounds, and heavy metals; and (5) Developing new mercury capturing sorbents and new

    This first Bill Brown SSP Technology Lecture covers the state-of-the-art (SOA) in wireless power transmission (WPT) technology including microwave and laser systems for the transfer of CW electric power, as related to eventually developing Space Solar Power (SSP) systems. Current and past technology accomplishments in ground based and air and space applied energy conversion devices, systems and modeling information is presented, where such data are known to the author. The purpose of the presentation is to discuss and present data to encourage documenting and breaking the current records, so as to advance the SOA in WPT for SSP. For example, regarding DC to RF and laser converters, 83% efficient 2.45 GHz cooker-tube magnetrons with 800 W CW output have been developed by CPII and the Russians. Over 50% wall-plug efficient 1.5 kW/cm 2 CW, water-cooled, multibeam, solid state laser diode bar-arrays have been developed by LLNL at 808 nm wavelength. The Germans have developed a 36% efficient, kW level, single coherent beam, lateral pumped semiconductor laser. The record for end-to-end DC input to DC output power overall WPT link conversion efficiency is 54% achieved during the Raytheon-JPL experiments in 1975 for 495.6 W recovered at 1.7 -m range, at 2.4469 GHz The record for usefully recovered electric power output (as contrasted with thermally induced power in structures) is 34 kW DC output at a range of 1.55 km, using 2.388 GHz microwaves, during the JPL-Raytheon experiments by Bill Brown and the author at Goldstone, CA in 1975. The GaAs-diode rectenna array had an average collection-conversion efficiency of 82.5%. A single rectenna element developed by Bill Brown demonstrated 91.4% efficiency. The comparable record for laser light to DC output power conversion efficiency of photovoltaics is 59%, for AlGaAs at 1.7 W and 826-nm wavelength.

  7. Emerging technologies in education and training: applications for the laboratory animal science community.

    2007-01-01

    This article examines several new and exciting communication technologies. Many of the technologies were developed by the entertainment industry; however, other industries are adopting and modifying them for their own needs. These new technologies allow people to collaborate across distance and time and to learn in simulated work contexts. The article explores the potential utility of these technologies for advancing laboratory animal care and use through better education and training. Descriptions include emerging technologies such as augmented reality and multi-user virtual environments, which offer new approaches with different capabilities. Augmented reality interfaces, characterized by the use of handheld computers to infuse the virtual world into the real one, result in deeply immersive simulations. In these simulations, users can access virtual resources and communicate with real and virtual participants. Multi-user virtual environments enable multiple participants to simultaneously access computer-based three-dimensional virtual spaces, called "worlds," and to interact with digital tools. They allow for authentic experiences that promote collaboration, mentoring, and communication. Because individuals may learn or train differently, it is advantageous to combine the capabilities of these technologies and applications with more traditional methods to increase the number of students who are served by using current methods alone. The use of these technologies in animal care and use programs can create detailed training and education environments that allow students to learn the procedures more effectively, teachers to assess their progress more objectively, and researchers to gain insights into animal care.

    Linear {alpha}-Olefins (LAOs) are used in several applications in chemical industry. Together with SABIC (Saudi Basic Industries Corporation) Linde jointly developed the {alpha}-SABLIN {sup registered} technology for a full range LAO plant as well as a 1-Hexene selective On Purpose technology (LAO OP) to cover the rapidly increasing demand for this specific comonomer. The {alpha}-SABLIN {sup registered} as well as the LAO OP technology are both homogenously catalyzed systems. This is raising special challenges concerning process and reactor design compared to much more established heterogeneous systems in chemical industry. E.g., the reactor concept is a bubble-column which allows efficient mixing as well as cooling of the reaction mixture. The development of the process was based on laboratory experiments which - based on an initial conceptual design for a large scale technical process - were first transformed into a pilot device before the commercial plant was designed, engineered and successfully started up and declared as commercialized. Today the {alpha}-SABLIN {sup registered} technology is the only LAO technology with a commercial reference which is free for licensing. A lot of experience and knowledge from the {alpha}-SABLIN development and commercial operation was gained. Although newly developed LAO OP technology is based on a different catalytic system, this experience is now utilized and transformed within the commercialization of this new technological development.

Tertiary hospital. A total of 987 consecutive women who had undergone ART during 1996-2007 were invited and altogether 505 women participated in the study. A postal enquiry with a life satisfaction scale. Self-reported life satisfaction in respect to the time since the last ART. In general, women who achieved a live birth after ART had a significantly higher life satisfaction than those who had unsuccessful ART, especially when compared in the first three years. The difference disappeared in the time period of 6-9 years after ART. The unsuccessfully treated women who had a child by some other means before or after the unsuccessful ART had comparable life satisfaction with successfully treated women even earlier. Even if unsuccessful ART outcome is associated with subsequent lower level of life satisfaction, it does not seem to threaten the long-term wellbeing.

    KPIs have been employed for internal quality control (IQC) in ART. However, clinical KPIs (C-KPIs) such as age, AMH and number of oocytes collected are never added to laboratory KPIs (L-KPIs), such as fertilization rate and morphological quality of the embryos for analysis, even though the final endpoint is the evaluation of clinical pregnancy rates. This paper analyzed if a KPIs-score strategy with clinical and laboratorial parameters could be used to establish benchmarks for IQC in ART cycles. In this prospective cohort study, 280 patients (36.4±4.3years) underwent ART. The total KPIs-score was obtained by the analysis of age, AMH (AMH Gen II ELISA/pre-mixing modified, Beckman Coulter Inc.), number of metaphase-II oocytes, fertilization rates and morphological quality of the embryonic lot. The total KPIs-score (C-KPIs+L-KPIs) was correlated with the presence or absence of clinical pregnancy. The relationship between the C-KPIs and L-KPIs scores was analyzed to establish quality standards, to increase the performance of clinical and laboratorial processes in ART. The logistic regression model (LRM), with respect to pregnancy and total KPIs-score (280 patients/102 clinical pregnancies), yielded an odds ratio of 1.24 (95%CI = 1.16-1.32). There was also a significant difference (pperformed to assess quality standards. This total KPIs-score could set up benchmarks for clinical pregnancy. Moreover, IQC can use C-KPIs and L-KPIs scores to detect problems in the clinical-laboratorial interface.

    The Idaho National Engineering Laboratory (INEL) Technology Logic Diagram (TLD) was developed to provide a decision support tool that relates Environmental Restoration (ER) and Waste Management (WM) problems at the INEL to potential technologies that can remediate these problems. The TLD identifies the research, development, demonstration, testing, and evaluation needed to develop these technologies to a state that allows technology transfer and application to an environmental restoration need. It is essential that follow-on engineering and system studies be conducted to build on the output of this project. These studies will begin by selecting the most promising technologies identified in this TLD and finding an optimum mix of technologies that will provide a socially acceptable balance between cost and risk to meet the site windows of opportunity. The TLD consists of three separate volumes: Volume I includes the purpose and scope of the TLD, a brief history of the INEL Waste Area Groups, and environmental problems they represent. A description of the TLD, definitions of terms, a description of the technology evaluation process, and a summary of each subelement, is presented. Volume II describes the overall layout and development of the TLD in logic diagram format. This section addresses the environmental restoration of contaminated INEL sites. Volume III (this volume) provides the Technology Evaluation Data Sheets (TEDS) for Environmental Restoration and Waste Management (EM) activities that are reference by a TEDS code number in Volume II. Each of these sheets represents a single logic trace across the TLD. These sheets contain more detail than provided for technologies in Volume II. Data sheets are arranged alphanumerically by the TEDS code number in the upper right corner of each sheet

    Cyclodextrins (CDs) are versatile excipients with an essential role in drug delivery, as they can form non-covalently bonded inclusion complexes (host-guest complexes) with several drugs either in solution or in the solid state. The main purpose of this publication was to carry out a state of the art of CDs as complexing agents in drug carrier systems. In this way, the history, properties and pharmaceutical applications of the CDs were highlighted with typical examples. The methods to enhance the complexation efficiency (CE) and the CDs applications in solid dosage forms were emphasized in more detail. The main advantages of using these cyclic oligosaccharides are as follows: (1) to enhance solubility/dissolution/ bioavailability of poorly soluble drugs; (2) to enhance drug stability; (3) to modify the drug release site and/or time profile; and (4) to reduce drug side effects (for example, gastric or ocular irritation). These compounds present favorable toxicological profile for human use and therefore there are various medicines containing CDs approved by regulatory authorities worldwide. On the other hand, the major drawback of CDs is the increase in formulation bulk, once the CE is, in general, very low. This aspect is particularly relevant in solid dosage forms and limits the use of CDs to potent drugs. CDs have great potential as drug carriers in Pharmaceutical Technology and can be used by the formulator in order to improve the drug properties such as solubility, bioavailability and stability. Additionally, recent studies have shown that these compounds can be applied as active pharmaceutical ingredients.

    2006-05-01

    Details of the first mammal born after nuclear transfer cloning were published by Steen Malte Willadsen in 1986. In spite of its enormous scientific significance, this discovery failed to trigger much public concern, possibly because the donor cells were derived from pre-implantation stage embryos. The major breakthrough in terms of public recognition has happened when Ian Wilmut et al. [Wilmut, I., Schnieke, A.E., McWhir, J., Kind, A.J., Campbell, K.H., 1997. Viable offspring derived from fetal és adult mammalian cells. Nature 385, 810-813] described the successful application of almost exactly the same method, but using the nuclei of somatic cells from an adult mammal, to create Dolly the sheep. It has become theoretically possible to produce an unlimited number of genetic replicates from an adult animal or a post-implantation foetus. Since 1997 a number of different species including pigs, goats, horses, cats, etc. have been cloned with the somatic cell nuclear transfer technique. Although the technology still has relatively low success rates and there seems to be substantial problems with the welfare of some of the cloned animals, cloning is used both within basic research and the biomedical sector. The next step seems to be to implement cloning in the agricultural production system and several animals have been developed in this direction. This article reviews the current state of the art of farm animal cloning from a scientific and technological perspective, describes the animal welfare problems and critically assess different applications of farm animal cloning. The scope is confined to animal biotechnologies in which the use of cell nuclear transfer is an essential part and extends to both biomedical and agricultural applications of farm animal cloning. These applications include the production of genetically identical animals for research purposes, and also the creation of genetically modified animals. In the agricultural sector, cloning can be used as a

    Purpose: The aim of this study was to demonstrate, based on clinical postplan dose distributions, that technology can be used efficiently to eliminate the learning curve associated with permanent seed implant planning and delivery. Methods and Materials: Dose distributions evaluated 30 days after the implant of the initial 22 consecutive patients treated with permanent seed implants at two institutions were studied. Institution 1 (I1) consisted of a new team, whereas institution 2 (I2) had performed more than 740 preplanned implantations over a 9-year period before the study. Both teams had adopted similar integrated systems based on three-dimensional (3D) transrectal ultrasonography, intraoperative dosimetry, and an automated seed delivery and needle retraction system (FIRST, Nucletron). Procedure time and dose volume histogram parameters such as D90, V100, V150, V200, and others were collected in the operating room and at 30 days postplan. Results: The average target coverage from the intraoperative plan (V100) was 99.4% for I1 and 99.9% for I2. D90, V150, and V200 were 191.4 Gy (196.3 Gy), 75.3% (73.0%), and 37.5% (34.1%) for I1 (I2) respectively. None of these parameters shows a significant difference between institutions. The postplan D90 was 151.2 Gy for I1 and 167.3 Gy for I2, well above the 140 Gy from the Stock et al. analysis, taking into account differences at planning, results in a p value of 0.0676. The procedure time required on average 174.4 min for I1 and 89 min for I2. The time was found to decrease with the increasing number of patients. Conclusion: State-of-the-art technology enables a new brachytherapy team to obtain excellent postplan dose distributions, similar to those achieved by an experienced team with proven long-term clinical results. The cost for bypassing the usual dosimetry learning curve is time, with increasing team experience resulting in shorter treatment times

    Successful pregnancy is the ultimate goal of almost all couples. However, this pleasant event is usually accompanied psychological and behavioral changes and can result in stress in women, particularly women who pregnant by assisted reproductive technology methods (ARTs). This study aims to determine the anxiety level during pregnancy and its relation with infertility factors in women who has been pregnant by Assisted Reproduction Technology (ART) methods. A total number of 100 ARTs pregnant women who came to three infertility centers in Tehran from August to November 2009 participated in this descriptive cross sectional study. The rational for selecting the subjects was their availability to the researcher at the time of the research. Anxiety was measured by Beck Anxiety Inventory and for obtaining the infertility data, a questionnaire designed by the researcher was given to the subjects. Data were statistically analyzed using the inferential statistic of chi-square. Study results showed that 34 % of subjects were anxious (moderate and sever levels in total). There are significant relations between infertility duration, history of treatment failure and anxiety level (P = 0.03) (P = 0.02). There were no statistically significant relationships with regard to other variables. Infertility duration and history of treatment failure in ARTs pregnant women are two factors that affect the anxiety level during pregnancy.

    Assisted reproduction technology laboratories have a very high degree of complexity. Mismatches of gametes or embryos can occur, with catastrophic consequences for patients. To minimize the risk of error, a multi-institutional working group applied failure mode and effects analysis (FMEA) to each critical activity/step as a method of risk assessment. This analysis led to the identification of the potential failure modes, together with their causes and effects, using the risk priority number (RPN) scoring system. In total, 11 individual steps and 68 different potential failure modes were identified. The highest ranked failure modes, with an RPN score of 25, encompassed 17 failures and pertained to "patient mismatch" and "biological sample mismatch". The maximum reduction in risk, with RPN reduced from 25 to 5, was mostly related to the introduction of witnessing. The critical failure modes in sample processing were improved by 50% in the RPN by focusing on staff training. Three indicators of FMEA success, based on technical skill, competence and traceability, have been evaluated after FMEA implementation. Witnessing by a second human operator should be introduced in the laboratory to avoid sample mix-ups. These findings confirm that FMEA can effectively reduce errors in assisted reproduction technology laboratories. Copyright © 2016 Reproductive Healthcare Ltd. Published by Elsevier Ltd.

    2003-01-01

    Determinations of patentability over the prior art are often thought to raise questions that are so technologically complex that they require special training and judgment to answer, especially in fast-moving fields like modern biotechnology. This essay explores the somewhat counterintuitive argument that under the U.S. system they do not and should not. According to this view, determinations of patentability over the prior art are based entirely on factual inquiries that are best made by lay judges and juries, just like the factual determinations these people regularly make in any ordinary nonpatent trial. This is good because judges and juries are adept at these determinations, and because appellate courts are adept at reviewing them. It leads to a system that is cheaper overall in allowing private litigants to better predict outcomes that also better approximate the correct answer than would be possible under other regimes premised upon the expert technological knowledge and judgment of a decisionmaker.

    Rapid development in the area of assisted reproductive technology (ART), has benefited mankind by addressing reproductive problems. However, the emergence of new technologies and techniques raises various issues and discussions among physicians and the masses, especially on issues related to bioethics. Apart from solutions provided using conventional bioethics framework, solutions can also be derived via a complementary framework of bioethics based on the Higher Objectives of the Divine Law (Maqasid al-Shariah) in tackling these problems. This approach in the Islamic World has been applied and localised in the Malaysian context. Thus, this paper highlights a conceptual theoretical framework for solving current bioethical issues, with a special focus on ART in the Malaysian context, and compares this theory with conventional theories of bioethics.

    Full Text Available Performing an art, either by painting or by sculpturing, requires to be interdisciplinary. When an artist creates his/her work of art, the process he/she realizes is supported by different engineering disciplines. Therefore, especially modern artists need to understand engineering science and this results in transforming artists into engineers. Opportunities provided by technology and science enable artists to expand his/her vision and to improve his/her works. Especially kinetic art has become an approach that combines art with engineering. Kinetic art, which is nourished with varied disciplines, is an excellent example to prove that art is interdisciplinary and to show the relationship between artist/art and engineering.

  20. Reducing cognitive load in the chemistry laboratory by using technology-driven guided inquiry experiments

    Science.gov (United States)

    Hubacz, Frank, Jr.

    The chemistry laboratory is an integral component of the learning experience for students enrolled in college-level general chemistry courses. Science education research has shown that guided inquiry investigations provide students with an optimum learning environment within the laboratory. These investigations reflect the basic tenets of constructivism by engaging students in a learning environment that allows them to experience what they learn and to then construct, in their own minds, a meaningful understanding of the ideas and concepts investigated. However, educational research also indicates that the physical plant of the laboratory environment combined with the procedural requirements of the investigation itself often produces a great demand upon a student's working memory. This demand, which is often superfluous to the chemical concept under investigation, creates a sensory overload or extraneous cognitive load within the working memory and becomes a significant obstacle to student learning. Extraneous cognitive load inhibits necessary schema formation within the learner's working memory thereby impeding the transfer of ideas to the learner's long-term memory. Cognitive Load Theory suggests that instructional material developed to reduce extraneous cognitive load leads to an improved learning environment for the student which better allows for schema formation. This study first compared the cognitive load demand, as measured by mental effort, experienced by 33 participants enrolled in a first-year general chemistry course in which the treatment group, using technology based investigations, and the non-treatment group, using traditional labware, investigated identical chemical concepts on five different exercises. Mental effort was measured via a mental effort survey, a statistical comparison of individual survey results to a procedural step count, and an analysis of fourteen post-treatment interviews. Next, a statistical analysis of achievement was

    Background: Transradial coronary angiography (TRA) has been associated with increased radiation doses. We hypothesized that contemporary image noise reduction technology would reduce radiation doses in the cardiac catheterization laboratory in a typical clinical setting. Methods and results: We performed a single-center, retrospective analysis of 400 consecutive patients who underwent diagnostic and interventional cardiac catheterizations in a predominantly TRA laboratory with traditional fluoroscopy (N = 200) and a new image noise reduction fluoroscopy system (N = 200). The primary endpoint was radiation dose (mGy cm{sup 2}). Secondary endpoints were contrast dose, fluoroscopy times, number of cineangiograms, and radiation dose by operator between the two study periods. Radiation was reduced by 44.7% between the old and new cardiac catheterization laboratory (75.8 mGy cm{sup 2} ± 74.0 vs. 41.9 mGy cm{sup 2} ± 40.7, p < 0.0001). Radiation was reduced for both diagnostic procedures (45.9%, p < 0.0001) and interventional procedures (37.7%, p < 0.0001). There was no statistically significant difference in radiation dose between individual operators (p = 0.84). In multivariate analysis, radiation dose remained significantly decreased with the use of the new system (p < 0.0001) and was associated with weight (p < 0.0001), previous coronary artery bypass grafting (p < 0.0007) and greater than 3 stents used (p < 0.0004). TRA was used in 90% of all cases in both periods. Compared with a transfemoral approach (TFA), TRA was not associated with higher radiation doses (p = 0.20). Conclusions: Image noise reduction technology significantly reduces radiation dose in a contemporary radial-first cardiac catheterization clinical practice. - Highlights: • Radial arterial access has been associated with higher doses compared to femoral access. • In a radial-first cardiac catheterization laboratory (90% radial) we examined radiation doses reduction with a contemporary image

    Corrosion is the degradation of a material that results from its interaction with the environment. The marine environment at NASAs Kennedy Space Center (KSC) has been documented by ASM International (formerly American Society for Metals) as the most corrosive in the United States. With the introduction of the Space Shuttle in 1981, the already highly corrosive conditions at the launch pads were rendered even more severe by the 70 tons of highly corrosive hydrochloric acid that were generated by the solid rocket boosters. Numerous failures at the launch pads are caused by corrosion.The structural integrity of ground infrastructure and flight hardware is critical to the success, safety, cost, and sustainability of space missions. As a result of fifty years of experience with launch and ground operations in a natural marine environment that is highly corrosive, NASAs Corrosion Technology Laboratory at KSC is a major source of corrosion control expertise in the launch and other environments. Throughout its history, the Laboratory has evolved from what started as an atmospheric exposure facility near NASAs launch pads into a world-wide recognized capability that provides technical innovations and engineering services in all areas of corrosion for NASA and external customers.This presentation will provide a historical overview of the role of NASAs Corrosion Technology in anticipating, managing, and preventing corrosion. One important challenge in managing and preventing corrosion involves the detrimental impact on humans and the environment of what have been very effective corrosion control strategies. This challenge has motivated the development of new corrosion control technologies that are more effective and environmentally friendly. Strategies for improved corrosion protection and durability can have a huge impact on the economic sustainability of human spaceflight operations.

    2014-01-01

    Increasingly stringent emission legislations, such as US 2010 and Euro VI, for NO x in mobile applications will require the use of intensification of NO x reduction aftertreatment technologies, such as the selective catalytic reduction (SCR). Due to the required higher deNO x efficiency, a lot of efforts have recently been concentrated on the optimization of the SCR systems for broadening the active deNO x temperature window as widely as possible, especially at low temperatures, enhancing the catalysts durability, and reducing the cost of the deNO x system. This paper provides a comprehensive overview of the state-of-the-art SCR technologies, including the alternative ammonia generation from the solid reductants, Vanadium-based, Cu-zeolite (CuZ) and Fe-zeolite (FeZ) based, and the novel chabazite zeolite with small pore size SCR catalysts. Furthermore, the progresses of the highly optimized hybrid approaches, involving combined CuZ and FeZ SCR, passive SCR, integration of DOC + (DPF, SCR), as well as SCR catalyst coated on DPF (referred as SCRF hereinafter) systems are well discussed. Even though SCR technology is considered as the leading NO x aftertreatment technology, attentions have been paid to the adverse by-products, such as NH 3 and N 2 O. Relevant regulations have been established to address the issues. - Highlights: •The review of state of the art technologies of selective catalytic reduction of NO x . •The mainstream V-based, Cu- and Fe-zeolite, and chabazite catalysts are illustrated. •The development of highly optimized hybrid integration SCR systems are analyzed. •The by-products of SCR systems and the corresponding regulations are discussed. •The future perspectives of the advanced SCR technologies are described

    There are complex causal associations between mental disorders, fertility treatment, fertility treatment outcome and infertility per se. Eating disorders cause endocrine disturbances, anovulation and thereby infertility, and research has shown that infertility as well as unsuccessful assisted reproductive technology (ART) treatment are potential risk factors for developing a depression on a long-term basis. Despite the fact that worldwide more than 400 000 ART treatment cycles are performed every year, the causal associations between mental disorders, use of medication for mental disorders and ART treatment in both sexes have only been sparsely explored. The main objective of this national register-based cohort study is to assess women's and men's mental health before, during, and after ART treatment in comparison with the mental health in an age-matched population-based cohort of couples with no history of ART treatment. Furthermore, the objective is to study the reproductive outcome of ART treatment among women who have a registered diagnosis of a mental disorder or have used medication for mental disorders prior to ART treatment compared with women in ART treatment without a mental disorder. We will establish the Danish National ART-Couple (DANAC) cohort including all women registered with ART treatment in the Danish in vitro fertilisation Register during 1994-2009 (N=42 915) and their partners. An age-matched population-based comparison cohort of women without ART treatment (n=215 290) and their partners will be established. Data will be cross-linked with data from national registers on psychiatric disorders, medical prescriptions for mental disorders, births, causes of deaths and sociodemographic data. Survival analyses and other statistical analyses will be conducted on the development of mental disorders and use of medication for mental disorders for women and men both prior to and after ART treatment.

    2012-05-01

    In the second part of this two-part series on the state-of-the-art comparability of corrected emission spectra, we have extended this assessment to the broader community of fluorescence spectroscopists by involving 12 field laboratories that were randomly selected on the basis of their fluorescence measuring equipment. These laboratories performed a reference material (RM)-based fluorometer calibration with commercially available spectral fluorescence standards following a standard operating procedure that involved routine measurement conditions and the data evaluation software LINKCORR developed and provided by the Federal Institute for Materials Research and Testing (BAM). This instrument-specific emission correction curve was subsequently used for the determination of the corrected emission spectra of three test dyes, X, QS, and Y, revealing an average accuracy of 6.8% for the corrected emission spectra. This compares well with the relative standard uncertainties of 4.2% for physical standard-based spectral corrections demonstrated in the first part of this study (previous paper in this issue) involving an international group of four expert laboratories. The excellent comparability of the measurements of the field laboratories also demonstrates the effectiveness of RM-based correction procedures.

    Wübben, Yvonne; Vöhringer, Margarete

    2009-03-01

    The introduction deals with two main issues: First, it focuses on the question why a history of scientific concepts should not be limited to the analysis of scientific texts alone. Secondly, it shows how the history of the reflex concept gains from looking at various fields such as art, literature and brain research. The crucial role the reflex played in 19th and 20th century and the different meanings it adopted allowed us to conclude with Bruno Latour that the distinction between art and science is in itself historical. Thus, the distinction proves to be of little use for the historiography of complex concepts such as the reflex which rarely appear to be purely scientific.

    Full Text Available The garden is a place of experimentation, where gardeners try out plants and both see how they grow and explore how to use them to eff ect, but does that make the garden a ‘laboratory’?Roberio Dias (2008 has described the Sitio Roberto Burle Marx (Roberto BurleMarx personal garden and nursery outside Rio de Janeiro, Brazil as a ‘landscapelaboratory’. Using the Sitio as a case study and Dias’s 2008 essay as a point ofdeparture, this paper asks, if a laboratory is ‘a room or building equipped forscientific experiments, research or teaching’, does the phrase ‘garden as laboratory’ accurately describe how the garden operates as a creative space? If it does not, what would be a more appropriate description?Considering the garden as an artist’s studio recognises that, even while science is involved in the process of growing plants, its aim is to cultivate plants for aesthetic purposes. If each plant is a test, and the tests interact ecologically, then the art produced in the garden as studio is of a radically diff erent type: a moving work of art. In reconceiving the garden as studio and its art as alive, I aim to help enrich theories of planting design to engage them with growth.

  10. Whose global art (history?: Ancient art as global art

    Directory of Open Access Journals (Sweden)

    Cynthia Colburn

    2016-12-01

    Full Text Available Discourse on global art or art history arguably dominates the field of art history today in terms of curriculum and research. This discourse cuts across time and space, impacting all art historical specializations, from prehistoric to contemporary, and from Africa to the Americas. Yet, the mainstream theoretical discourse on global art or art history focuses almost explicitly on contemporary and, to a lesser extent, modern art, operating from the premise that only these arts were created in an age of globalization and, thus, emphasize hybridity. This essay seeks to expand the mainstream theoretical discourse regarding global art to pre-modern examples, given that artistic exchange and hybridity dates as early as the prehistoric era all over the world and is not dependent on newer technologies. Indeed, one might argue that the study of pre-modern examples of global art could provide a powerful historical lens through which to analyze contemporary global art.

    Full Text Available Abstract Background High throughput gene expression profiling (GEP is becoming a routine technique in life science laboratories. With experimental designs that repeatedly span thousands of genes and hundreds of samples, relying on a dedicated database infrastructure is no longer an option. GEP technology is a fast moving target, with new approaches constantly broadening the field diversity. This technology heterogeneity, compounded by the informatics complexity of GEP databases, means that software developments have so far focused on mainstream techniques, leaving less typical yet established techniques such as Nylon microarrays at best partially supported. Results MAF (MicroArray Facility is the laboratory database system we have developed for managing the design, production and hybridization of spotted microarrays. Although it can support the widely used glass microarrays and oligo-chips, MAF was designed with the specific idiosyncrasies of Nylon based microarrays in mind. Notably single channel radioactive probes, microarray stripping and reuse, vector control hybridizations and spike-in controls are all natively supported by the software suite. MicroArray Facility is MIAME supportive and dynamically provides feedback on missing annotations to help users estimate effective MIAME compliance. Genomic data such as clone identifiers and gene symbols are also directly annotated by MAF software using standard public resources. The MAGE-ML data format is implemented for full data export. Journalized database operations (audit tracking, data anonymization, material traceability and user/project level confidentiality policies are also managed by MAF. Conclusion MicroArray Facility is a complete data management system for microarray producers and end-users. Particular care has been devoted to adequately model Nylon based microarrays. The MAF system, developed and implemented in both private and academic environments, has proved a robust solution for

    2014-07-01

    To assess the incidence of monozygotic twinning (MZT) among cases undergoing assisted reproductive technology (ART) treatment. We performed a retrospective observational study and analyzed the data of patients who were registered in the national ART registry system of Japan from January to December 2010; only the data of patients with single embryo transfer (ET) were included. Of 30,405 pregnancies, 425 resulted in MZT following fresh and frozenthawed ET. The MZT incidence among women undergoing ART was 1.4 %. Multiple logistic regression analysis indicated that cases undergoing fresh and frozen-thawed ET, blastocyst transfer had a significantly increased MZT rate (P < 0.01). Assisted hatching (AH) and frozen-thawed ET and maternal age did not significantly affect the MZT incidence. Of 8510 fresh ET pregnancies, 104 resulted in MZT. Multiple logistic regression analysis indicated that blastocyst transfer significantly increased the MZT rate in cases undergoing fresh ET. Ovarian stimulation, intracytoplasmic sperm injection, AH, and maternal age did not significantly affect the MZT incidence. Blastocyst transfer was associated with an increased MZT incidence. We have to be aware of the potential risk of MZT caused by blastocyst transfer. However, further studies are required to assess the correlation among specific AH types, embryo culture conditions, and MZT incidence.

    Roberts, Simon J.

    2014-01-01

    The Faculty of Engineering at The University of Nottingham, UK, has developed interdisciplinary, hands-on workshops for primary schools that introduce space technology, its relevance to everyday life and the importance of science, technology, engineering and maths. The workshop activities for 7-11 year olds highlight the roles that space and satellite technology play in observing and monitoring the Earth's biosphere as well as being vital to communications in the modern digital world. The programme also provides links to 'how science works', the environment and citizenship and uses pixel art through the medium of digital photography to demonstrate the importance of maths in a novel and unconventional manner. The interactive programme of activities provides learners with an opportunity to meet 'real' scientists and engineers, with one of the key messages from the day being that anyone can become involved in science and engineering whatever their ability or subject of interest. The methodology introduces the role of scientists and engineers using space technology themes, but it could easily be adapted for use with any inspirational topic. Analysis of learners' perceptions of science, technology, engineering and maths before and after participating in ENGage showed very positive and significant changes in their attitudes to these subjects and an increase in the number of children thinking they would be interested and capable in pursuing a career in science and engineering. This paper provides an overview of the activities, the methodology, the evaluation process and results.

    2017-10-01

    Electrostatic monitoring technology is a useful tool for monitoring and detecting component faults and degradation, which is necessary for system health management. It encompasses three key research areas: sensor technology; signal detection, processing and feature extraction; and verification experimentation. It has received considerable recent attention for condition monitoring due to its ability to provide warning information and non-obstructive measurements on-line. A number of papers in recent years have covered specific aspects of the technology, including sensor design optimization, sensor characteristic analysis, signal de-noising and practical applications of the technology. This paper provides a review of the recent research and of the development of electrostatic monitoring technology, with a primary emphasis on its application for the aero-engine gas path. The paper also presents a summary of some of the current applications of electrostatic monitoring technology in other industries, before concluding with a brief discussion of the current research situation and possible future challenges and research gaps in this field. The aim of this paper is to promote further research into this promising technology by increasing awareness of both the potential benefits of the technology and the current research gaps.

    This state-of-the-art report describes various technologies for offgas treatment. It provides comprehensive treatment technologies of the extensive subject such as particulates, radioactive iodine, carbon dioxide, Kr/Xe and Cs/Ru. This report also incorporates the wastes generation and its characteristics as well as the historical and current management practices. A number of review articles by experts in various area of concern and some of the removal systems that have been designed for power plants and, particularly, for spent fuel reusing plants are also involved. As a result, it can be drawn that the drying processes for offgas treatment have much benefits in standpoints of simplicity, economy, disposal safety and resource reuse rather than the wet processes.

  3. Synthesizing artificial cells from giant unilamellar vesicles: state-of-the art in the development of microfluidic technology.

    Science.gov (United States)

    Matosevic, Sandro

    2012-11-01

    Microfluidic technology - the manipulation of fluids at micrometer scales - has revolutionized many areas of synthetic biology. The bottom-up synthesis of "minimal" cell models has traditionally suffered from poor control of assembly conditions. Giant unilamellar vesicles (GUVs) are good models of living cells on account of their size and unilamellar membrane structure. In recent years, a number of microfluidic approaches for constructing GUVs has emerged. These provide control over traditionally elusive parameters of vesicular structure, such as size, lamellarity, membrane composition, and internal contents. They also address sophisticated cellular functions such as division and protein synthesis. Microfluidic techniques for GUV synthesis can broadly be categorized as continuous-flow based approaches and droplet-based approaches. This review presents the state-of-the-art of microfluidic technology, a robust platform for recapitulating complex cellular structure and function in synthetic models of biological cells.

    The marine environment at NASAs Kennedy Space Center (KSC) has been documented by ASM International (formerly American Society for Metals) as the most corrosive in North America. With the introduction of the Space Shuttle in 1981, the already highly corrosive conditions at the launch pads were rendered even more severe by the highly corrosive hydrochloric acid (HCl) generated by the solid rocket boosters (SRBs). Numerous failures at the launch pads are caused by corrosion. The structural integrity of ground infrastructure and flight hardware is critical to the success, safety, cost, and sustainability of space missions. NASA has over fifty years of experience dealing with unexpected failures caused by corrosion and has developed expertise in corrosion control in the launch and other environments. The Corrosion Technology Laboratory at KSC evolved, from what started as an atmospheric exposure test site near NASAs launch pads, into a capability that provides technical innovations and engineering services in all areas of corrosion for NASA, external partners, and customers.This paper provides a chronological overview of NASAs role in anticipating, managing, and preventing corrosion in highly corrosive environments. One important challenge in managing and preventing corrosion involves the detrimental impact on humans and the environment of what have been very effective corrosion control strategies. This challenge has motivated the development of new corrosion control technologies that are more effective and environmentally friendly. Strategies for improved corrosion protection and durability can have a huge impact on the economic sustainability of human spaceflight operations.

    Does a genetic link and/or a child's age influence a parent's willingness to talk to a child about how they were conceived? The presence/absence of a biological link and the child's age clearly influences the disclosure process. The research published to date has yielded diverse findings on autologous and donor assisted reproductive technology (ART) parents' disclosure of the conception method to their children and on the ages at which the children are informed, if told. A systematic review and meta-analysis were carried out. A search of MEDLINE and PUBMED was run for English-language studies published from January 1996 through January 2015. A total of 26 studies were included in the systematic review, 19 of which were included in the meta-analysis. A total of 2814 parent responses were included in the systematic review. Two authors independently assessed the studies for review inclusion. Selection criteria were: peer-reviewed studies, quantitative studies only, research conducted after the birth of ART-conceived children, number of parent responses on disclosure status reported in terms of Told, Plan to tell, Uncertain, Plan to not tell. Thirty-two (32) study-level effect size statistics were included in the meta-analysis. Three authors independently assessed the risk of bias. Among parents who responded, 23% of the total number of parent responses indicated that they had already Told; 44% were Planning to tell; 13% were Uncertain and 20% were Planning to not tell their children about their ART conception. Meta-analysis gave no statistically significant differences between autologous and donor ART in the ART (Cohen's h = 0.86): Planning to tell showed a higher probability in the 10 years age group for the autologous ART subsample, than in the donor ART subsample (Cohen's h = 0.89). All parents participated voluntarily in the studies and may have influenced the data in the direction of disclosure thereby. The reviewed studies, moreover, differed in terms of

    A significant number of steam generator tubes are defective and are removed from service or repaired world widely. This wide spread damage has been caused by diverse degradation mechanisms, some of which are difficult to detect and predict. Regarding domestic nuclear power plants, also, the increase of number of operating nuclear power plants and operating periods may result in the increase of steam generator tube failure. So, it is important to carry out the integrity evaluation process to prevent the steam generator tube damage. There are two objectives of this research. The one is to make database for the research of steam generator at domestic research institution. It will increase the efficiency and capability of limited domestic research resources by sharing data and information through network organization. Also, it will enhance the current standard of integrity evaluation procedure that is considerably conservative but can be more reasonable. The second objective is to establish the standard integrity evaluation procedure for steam generator tube by reviewing state of the art technology. The research resources related to steam generator tubes are managed by the established web-based database system. The following topics are covered in this project: development of web-based network for research on steam generator tubes review of state of the art technology.

    Monitoring of student learning through systematic formative assessment is important for adjusting pedagogical strategies. However, traditional formative assessments, such as quizzes and written assignments, may not be sufficiently timely for making adjustments to a learning process. Technology supported formative assessment tools assess student knowledge, allow for immediate feedback, facilitate classroom dialogues, and have the potential to modify student learning strategies. As an attempt to integrate technology supported formative assessment in the laboratory section of an upper-level histology course, the interactive application Learning Catalytics TM , a cloud-based assessment system, was used. This study conducted during the 2015 Histology courses at Cornell University concluded that this application is helpful for identifying student misconceptions "on-the-go," engaging otherwise marginalized students, and forming a new communication venue between students and instructors. There was no overall difference between grades from topics that used the application and grades from those that did not, and students reported that it only slightly helped improve their understanding of the topic (3.8 ± 0.99 on a five-point Likert scale). However, they highly recommended using it (4.2 ± 0.71). The major limitation was regarding the image display and graphical resolution of this application. Even though students embrace the use of technology, 39% reported benefits of having the traditional light microscope available. This cohort of students led instructors to conclude that the newest tools are not always better, but rather can complement traditional instruction methods.

    2013-07-15

    The study by CE Delft and the German Aerospace Center (DLR), commissioned by the International Council on Clean Transportation (ICCT), surveys the technology potential for zero-emission road freight transport in the EU. For short distance transport, battery electric technology is feasible, as distribution trucks have lower range requirements and recharging can occur at scheduled downtimes (e.g. overnight). For long haul applications, battery electric vehicles coupled with overhead wires (catenary) or in-road charging (dynamic) infrastructure are possible, as well as fuel cell drivelines. The cost differential between conventional and zero emission HDVs will diminish over the next 10-15 years, as fuel savings offset other costs. If zero-emission technologies are introduced on a large scale in the onroad freight transport sector beginning in 2020, the total end-user costs will not significantly increase. The total cost of ownership within this study do not consider required infrastructure investments. All zero emission technologies require major infrastructure investments, whether hydrogen refuelling stations, in-road inductive charging, or other systems. Broad policy support is needed to encourage the development and evaluation of various technology options. Over time, the policy focus must shift from stimulating innovation and technology adoption to regulation, if it is to spur a successful transformation of the truck market.

    In the 15th century, brain illustration began to change from a schematic system that involved scant objective rendering of the brain, to accurate depictions based on anatomical dissections that demanded significant artistic talent. Notable examples of this innovation are the drawings of Leonardo da Vinci (1498-1504), Andreas Vesalius' association with the bottega of Titian to produce the drawings of Vesalius' De humani corporis fabrica (1543), and Christopher Wren's illustrations for Thomas Willis' Cerebri Anatome (1664). These works appeared during the Renaissance and Age of Enlightenment, when advances in brain imaging, or really brain rendering, reflected not only the abilities and dedications of the artists, but also the influences of important cultural and scientific factors. Anatomy and human dissection became popular social phenomena as well as scholarly pursuits, linked with the world of the fine arts. The working philosophy of these artists involved active participation in both anatomical study and illustration, and the belief that their discoveries of the natural world could best be communicated by rendering them in objective form (that is, with realistic perspective). From their studies emerged the beginning of contemporary brain imaging. In this article, the authors examine how the brain began to be imaged in realism within a cultural and scientific milieu that witnessed the emergence of anatomical dissection, the geometry of linear perspective, and the closer confluence of art and science.

    2014-07-01

    Neurosurgery is one of the most demanding surgical specialties in terms of precision requirements and surgical field limitations. Recent advancements in robotic technology have generated the possibility of incorporating advanced technological tools to the neurosurgical operating room. Although previous studies have addressed the specific details of new robotic systems, there is very little literature on the strengths and drawbacks of past attempts, currently available platforms and prototypes in development. In this review, the authors present a critical historical analysis of the development of robotic technology in neurosurgery as well as a comprehensive summary of the currently available systems that can be expected to be incorporated to the neurosurgical armamentarium in the near future. Finally, the authors present a critical analysis of the main technical challenges in robotic technology development at the present time (such as the design of improved systems for haptic feedback and the necessity of incorporating intraoperative imaging data) as well as the benefits which robotic technology is expected to bring to specific neurosurgical subspecialties in the near future.

    The existing Los Alamos National Laboratory TA-50 liquid radioactive waste treatment plant RLWP has been in service for over thirty years, during this period many technical, regulatory, and processing changes have occurred. The existing facility can no longer comply with the demands and requirements for continued operation, and would not be able to comply with anticipated stringent future contaminant discharge limitations. Either a major upgrading or replacement of the existing facility is required. In order to assess the most appropriate means of providing an adequate facility to comply with predicted requirements for Ta-50, this Best Available Technology (BAT) Study was conducted to compare feasible technical and economic alternatives in order to define the most favorable technology configuration. This report consists of eleven sections. Section 1 provides a general introduction and background of the TA-50 operations and the basis for this study. Section 2 provides a technical discussion of the unit processes at TA-50 and several other comparable operations at other DOE sites. Section 3 addresses the evaluation and selection of appropriate treatment processes. Section 4 provides an analysis of environmental issues and concerns. Section 5 presents the rationale for the selection of preferred process configurations. Section 6 is the evaluation of operational issues. Section 7 addresses energy and resource use topics. Section 8 provides an economic analysis, and Section 9 summarizes the evaluation and the identification of the BAT. These sections are augmented by appendices. The report identifies the construction of a new radioactive liquid waste treatment facility as the BAT. Based on the information analyzed for this study, this option appears to provide the best combination of environmental compliance, operability, and economic value

    Pregnancies achieved through medical treatments following a period of infertility may demand extra emotional and practical investment from women. This paper aims at understanding the experience of pregnancy after Assisted Reproductive Technology, and exploring whether this experience is affected by previous failed infertility treatments. This paper uses a qualitative approach. Participants were nineteen expectant first-time mothers from Brazil who conceived through Assisted Reproductive Technology treatment. During the third trimester of gestation, a semi-structured interview was administered to assess perceptions of and feelings about treatment and pregnancy. Interview transcripts were analysed using thematic analysis, and the sample was divided into two groups according to whether it was the participant's first treatment or not. Themes identified include: tolerance of the demands of treatment and pregnancy, consideration of the mechanics of treatment and pregnancy, and emotionally painful aspects of treatment and pregnancy. Pregnancy itself was regarded as a reward or compensation for the difficulties undergone. Perspectives differed according to whether pregnancy followed the first Assisted Reproductive Technology treatment; those who had undergone previously unsuccessful treatments focused less on the mechanical aspects of the process but were more concerned about possible physical problems. The similarities and differences found according to number of treatments attempted should be taken into consideration when providing psychological support for expectant Assisted Reproductive Technology mothers.

    2016-02-01

    Laboratory cadaver dissection is essential for three-dimensional understanding of anatomical structures and variability, but there are many challenges to teaching gross anatomy in medical and dental schools, including a lack of available space and qualified anatomy faculty. The aim of this study was to determine the efficacy of high-definition audiovisual educational technology in the gross anatomy laboratory in improving dental students' learning outcomes and satisfaction. Exam scores were compared for two classes of first-year students at one U.S. dental school: 2012-13 (no audiovisual technology) and 2013-14 (audiovisual technology), and section exams were used to compare differences between semesters. Additionally, an online survey was used to assess the satisfaction of students who used the technology. All 284 first-year students in the two years (2012-13 N=144; 2013-14 N=140) participated in the exams. Of the 140 students in the 2013-14 class, 63 completed the survey (45% response rate). The results showed that those students who used the technology had higher scores on the laboratory exams than those who did not use it, and students in the winter semester scored higher (90.17±0.56) than in the fall semester (82.10±0.68). More than 87% of those surveyed strongly agreed or agreed that the audiovisual devices represented anatomical structures clearly in the gross anatomy laboratory. These students reported an improved experience in learning and understanding anatomical structures, found the laboratory to be less overwhelming, and said they were better able to follow dissection instructions and understand details of anatomical structures with the new technology. Based on these results, the study concluded that the ability to provide the students a clear view of anatomical structures and high-quality imaging had improved their learning experience.

    This report is to present the progress made on the project entitled ''Establishment of an Environmental Control Technology Laboratory (ECTL) with a Circulating Fluidized-Bed Combustion (CFBC) System'' during the period July 1, 2006 through September 30, 2006. The following activities have been completed: the steel floor grating around the riser in all levels and the three-phase power supply for CFBC System was installed. Erection of downcomers, loop seals, ash bunker, thermal expansion joints, fuel and bed material bunkers with load cells, rotary air-lock valves and fuel flow monitors is underway. Pilot-scale slipstream tests conducted with bromine compound addition were performed for two typical types of coal. The purposes of the tests were to study the effect of bromine addition on mercury oxidization. From the test results, it was observed that there was a strong oxidization effect for Powder River Basin (PRB) coal. The proposed work for next quarter and project schedule are also described.

    The PNL staff has been studying fusion technology in areas such as economics, fusion-fission hybrid concepts, materials, neutronics, environment and safety. These studies have been scoped to make efficient use of ERDA resources, and to complement and support efforts at other laboratories. The effect the plasma and associated radiation and emission will have upon the surfaces of the first wall are being studied. Neutron sputtering experiments were made on niobium and gold and the results were evaluated for absolute neutron yields. Molybdenum and vanadium were studied for effects of ion bombardment under various conditions of helium injection. Graphite cloth is being irradiated for examination of radiation effects because it is suggested for use in several CTR concepts as a shield between the plasma and the first wall. Helium effects are being studied to characterize degradation of structural metal properties. Work is progressing on absolute measurement of the electrical resistivity of insulators and the demonstration of the feasibility of producing insulating coatings by sputter deposition

    Spent nuclear fuel research and development activities are conducted in accordance with Section 218 of the 1982 Nuclear Waste Policy Act (NWPA). Major objectives of Section 218 are to encourage and expedite the efficient use of existing storage facilities and the addition of new at-reactor storage capacity. Activities at the Idaho Engineering Laboratory (INEL) are pertinent to the following objectives: A cooperative demonstration program with the private sector to develop dry storage technologies that the Nuclear Regulatory Commission (NRC) can generically approve; A cost-shared dry storage research and development program at Federal facilities to collect the necessary licensing data. These items are supported by tasks being performed at the INEL. Research and development programs include the testing of metal storage casks containing either consolidated or intact spent fuel in inert gas atmospheres. The casks, weighing nearly 90,718 kg (100 tons), are fabricated using nodular cast iron or forged carbon steel and contain basket assemblies which provide criticality control and spacing of fuel assemblies in individual cells. Small-scale rod consolidation systems are also being developed

    The program goal for shallow land burial (SLB) Technology Development at the Los Alamos National Laboratory is to field test new disposal concepts and strategies for all aspects of arid SLB on an accelerated basis and on a reasonable scale. The major accomplishments during FY-1981 were the development of the Los Alamos Experimental Engineered Test Facility, the emplacement of the biointrusion barrier testing experiments, the design and emplacement of the moisture cycling experiments, the design and construction of the experiment clusters, and the planning for the experiments to be emplaced in these units. This paper will describe the site development work, the design and construction of the experiment clusters, and the experiments planned for these units. The experimental Engineered Test Facility was brought from idea to reality and two experiments were emplaced (biointrusion barrier and moisture cycling). The experiment clusters were designed and constructed, and are now available for experimentation. These units are reusable. After an experiment is complete it can be removed and another experiment put in its place. Several of the experiments were planned and designed while some of the other experiments are still in the planning stage. Based on the work done in FY-1981, significant progress toward Milestones, C, D, and E should be made in FY-1982

    Mobile technologies offer new opportunities to improve dissection learning. This study examined the effect of using an iPad-based multimedia dissection manual during anatomy laboratory instruction on learner's perception of anatomy dissection activities and use of time. Three experimental dissection tables used iPads and three tables served as a control for two identical sessions. Trained, non-medical school anatomy faculty observers recorded use of resources at two-minute intervals for 20 observations per table. Students completed pre- and post-perception questionnaires. We used descriptive and inferential analyses. Twenty-one control and 22 experimental students participated. Compared with controls, experimental students reported significantly (P learning anatomy. Experimental students indicated that the iPad helped them in dissection. We observed experimental students more on task (93% vs. 83% of the time) and less likely to be seeking an instructor (2% vs. 32%). The groups received similar attention from instructors (33% vs. 37%). Fifty-nine percent of the time at least one student was looking at the iPad. Groups clustered around the iPad a third of their time. We conclude that the iPad-manual aided learner engagement, achieved instructional objectives, and enhanced the effectiveness and efficiency of dissection education.

    The diffusion of minimally invasive surgery has thrived in recent years, providing substantial benefits over traditional techniques for a number of surgical interventions. This rapid growth has been possible due to significant advancements in medical technology, which partly solved some of the technical and clinical challenges associated with minimally invasive techniques. The issues that still limit its widespread adoption for some applications include the limited field of view; reduced manoeuvrability of the tools; lack of haptic feedback; loss of depth perception; extended learning curve; prolonged operative times and higher financial costs. The present review discusses some of the main recent technological advancements that fuelled the uptake of minimally invasive surgery, focussing especially on the areas of imaging, instrumentation, cameras and robotics. The current limitations of state-of-the-art technology are identified and addressed, proposing future research directions necessary to overcome them. Published by the BMJ Publishing Group Limited.

    The increasingly stringent emission regulations, such as US 2010, Tier 2 Bin 5 and beyond, off-road Tier 4 final, and Euro V/5 for particulate matter (PM) reduction applications, will mandate the use of the diesel particulate filters (DPFs) technology, which is proven to be the only way that can effectively control the particulate emissions. This paper covers a comprehensive overview of the state-of-the-art DPF technologies, including the advanced filter substrate materials, the novel catalyst formulations, the highly sophisticated regeneration control strategies, the DPF uncontrolled regenerations and their control methodologies, the DPF soot loading prediction, and the soot sensor for the PM on-board diagnostics (OBD) legislations. Furthermore, the progress of the highly optimized hybrid approaches, which involves the integration of diesel oxidation catalyst (DOC) + (DPF, NOx reduction catalyst), the selective catalytic reduction (SCR) catalyst coated on DPF, as well as DPF in the high-pressure exhaust gas recirculation (EGR) loop systems, is well discussed. Besides, the impacts of the quality of fuel and lubricant on the DPF performance and the maintenance and retrofit of DPF are fully elaborated. Meanwhile, the high efficiency gasoline particulate filter (GPF) technology is being required to effectively reduce the PM and particulate number (PN) emissions from the gasoline direct injection (GDI) engines to comply with the future increasingly stricter emissions regulations.

    1984-01-01

    The features of incineration treatment as the method of treating radioactive wastes are the effect of volume reduction and inorganic stabilization (change to ash). The process of incineration treatment is roughly divided into dry process and wet process. But that in practical use is dry incineration by excess air combustion or suppressed combustion. The important things in incineration techniques are the techniques of exhaust gas treatment as well as combustion techniques. In Europe and USA, incineration has been practiced in laboratories and reprocessing plants for low level combustible solids, but the example of application in nuclear power stations is few. In Japan, though the fundamental techniques are based on the introduction from Europe, the incineration treatment of combustible solids has been carried out in laboratories, reprocessing plants, nuclear fuel production facilities and also nuclear power stations. The techniques of solidifying ash by incineration and the techniques of incinerating spent ion exchange resin are actively developed, and the development of the treatment of radioactive wastes in the lump including incineration also is in progress.

    State-of-the-art life support carbon dioxide (CO2) reduction technology, based on the Sabatier reaction, is theoretically capable of 50% recovery of oxygen from metabolic CO2. This recovery is constrained by the limited availability of reactant hydrogen. Post-processing of the methane byproduct from the Sabatier reactor results in hydrogen recycle and a subsequent increase in oxygen recovery. For this purpose, a Methane Post-Processor Assembly containing three sub-systems has been developed and tested. The assembly includes a Methane Purification Assembly (MePA) to remove residual CO2 and water vapor from the Sabatier product stream, a Plasma Pyrolysis Assembly (PPA) to partially pyrolyze methane into hydrogen and acetylene, and an Acetylene Separation Assembly (ASepA) to purify the hydrogen product for recycle. The results of partially integrated testing of the sub-systems are reported

    It is estimated by 2050 that one-third of Europe's population will be over 60. Life expectancy has on average already risen by 2.5 years per decade and the number of old people aged 80+ is expected to grow by 180%. Nowadays, there are 5.5 million cases of Alzheimer-afflicted people in Europe and more new cases being added every year. In fact Alzheimer's disease has been called the "plague of the twenty-first century". There is currently no cure for this disease; however, prevention and early diagnosis may play a huge role in delaying the onset of the worst effects of this severe disease. Modern technologies could have an important role to satisfy main needs of people with dementia. Nonetheless, despite recent advancements in information and communication technologies and growing sales numbers, industry has been rather reluctant to standardise access technologies and to implement them in a "Design for All approach". Because of this, in last years, there have been launched in Europe a great number of initiatives, both public and private, which try to improve the situation of those persons who suffer this ailment and that will be detailed in this chapter.

  18. What can science and technology studies learn from art and design? Reflections on 'Synthetic Aesthetics'.

    Science.gov (United States)

    Calvert, Jane; Schyfter, Pablo

    2017-04-01

    In this paper we reflect on a project called 'Synthetic Aesthetics', which brought together synthetic biologists with artists and designers in paired exchanges. We - the STS researchers on the project - were quickly struck by the similarities between our objectives and those of the artists and designers. We shared interests in forging new collaborations with synthetic biologists, 'opening up' the science by exploring implicit assumptions, and interrogating dominant research agendas. But there were also differences between us, the most important being that the artists and designers made tangible artefacts, which had an immediacy and an ability to travel, and which seemed to allow different types of discussions from those initiated by our academic texts. The artists and designers also appeared to have the freedom to be more playful, challenging and perhaps subversive in their interactions with synthetic biology. In this paper we reflect on what we learned from working with the artists and designers on the project, and we argue that engaging more closely with art and design can enrich STS work by enabling an emergent form of critique.

    Full Text Available The results of a diagnostic survey on the materials of representative Art Nouveau buildings in Italy, Portugal and Poland are here presented and compared, as a contribution to their understanding and, hence, to support compatible restoration. In particular, the facade decorations were investigated for the appraisal of their materials and technologies, often neglected in current maintenance/restoration works and so cancelled, leading to a severe loss in architectural image. The ongoing diagnostic campaign, in collaboration among different universities, is aimed to set up a database on materials and technologies of Art Nouveau facade decorations at a European scale, as a technical-scientific background for the highlighting of preservation guidelines.

    En este trabajo se presentan los resultados de un estudio de diagnóstico sobre materiales representativos de edificios del periodo del Modernismo en Italia, Portugal y Polonia. Con la comparación de estos resultados se pretende contribuir a incrementar el conocimiento de los materiales usados en este patrimonio, que permita realizar más eficazmente las futuras intervenciones de restauración. En particular, se analizan las decoraciones de las fachadas, pasando por el reconocimiento de sus materiales constituyentes y de las tecnologías usadas, que muchas veces no son adecuadamente estudiados en intervenciones de mantenimiento y/o restauración, provocando graves pérdidas en su imagen y lenguaje arquitectónico original. Con la campaña de trabajos de diagnóstico, en colaboración con varias universidades, se pretende crear una base de datos sobre materiales y tecnologías usados en las decoraciones de fachada en el periodo del Modernismo a una escala europea. El material podrá constituirse en una herramienta técnico-científica de soporte al desarrollo de directrices y recomendaciones para la preservación de este patrimonio.

  20. Restricting Access to ART on the Basis of Criminal Record : An Ethical Analysis of a State-Enforced "Presumption Against Treatment" With Regard to Assisted Reproductive Technologies.

    Thompson, Kara; McDougall, Rosalind

    2015-09-01

    As assisted reproductive technologies (ART) become increasingly popular, debate has intensified over the ethical justification for restricting access to ART based on various medical and non-medical factors. In 2010, the Australian state of Victoria enacted world-first legislation that denies access to ART for all patients with certain criminal or child protection histories. Patients and their partners are identified via a compulsory police and child protection check prior to commencing ART and, if found to have a previous relevant conviction or child protection order, are given a "presumption against treatment." This article reviews the legislation and identifies arguments that may be used to justify restricting access to ART for various reasons. The arguments reviewed include limitations of reproductive rights, inheriting undesirable genetic traits, distributive justice, and the welfare of the future child. We show that none of these arguments justifies restricting access to ART in the context of past criminal history. We show that a "presumption against treatment" is an unjustified infringement on reproductive freedom and that it creates various inconsistencies in current social, medical, and legal policy. We argue that a state-enforced policy of restricting access to ART based on the non-medical factor of past criminal history is an example of unjust discrimination and cannot be ethically justified, with one important exception: in cases where ART treatment may be considered futile on the basis that the parents are not expected to raise the resulting child.

  3. Adipose Tissue and Mesenchymal Stem Cells: State of the Art and Lipogems® Technology Development.

    Science.gov (United States)

    Tremolada, Carlo; Colombo, Valeria; Ventura, Carlo

    In the past few years, interest in adipose tissue as an ideal source of mesenchymal stem cells (MSCs) has increased. These cells are multipotent and may differentiate in vitro into several cellular lineages, such as adipocytes, chondrocytes, osteoblasts, and myoblasts. In addition, they secrete many bioactive molecules and thus are considered "mini-drugstores." MSCs are being used increasingly for many clinical applications, such as orthopedic, plastic, and reconstructive surgery. Adipose-derived MSCs are routinely obtained enzymatically from fat lipoaspirate as SVF and/or may undergo prolonged ex vivo expansion, with significant senescence and a decrease in multipotency, leading to unsatisfactory clinical results. Moreover, these techniques are hampered by complex regulatory issues. Therefore, an innovative technique (Lipogems®; Lipogems International SpA, Milan, Italy) was developed to obtain microfragmented adipose tissue with an intact stromal vascular niche and MSCs with a high regenerative capacity. The Lipogems® technology, patented in 2010 and clinically available since 2013, is an easy-to-use system designed to harvest, process, and inject refined fat tissue and is characterized by optimal handling ability and a great regenerative potential based on adipose-derived MSCs. In this novel technology, the adipose tissue is washed, emulsified, and rinsed and adipose cluster dimensions gradually are reduced to about 0.3 to 0.8 mm. In the resulting Lipogems® product, pericytes are retained within an intact stromal vascular niche and are ready to interact with the recipient tissue after transplantation, thereby becoming MSCs and starting the regenerative process. Lipogems® has been used in more than 7000 patients worldwide in aesthetic medicine and surgery, as well as in orthopedic and general surgery, with remarkable and promising results and seemingly no drawbacks. Now, several clinical trials are under way to support the initial encouraging outcomes

    Electroencephalography (EEG) has emerged as a powerful tool for quantitatively studying the brain that enables natural and mobile experiments. Recent advances in EEG have allowed for the use of dry electrodes that do not require a conductive medium between the recording electrode and the scalp. The overall goal of this research was to gain an understanding of the overall usability and signal quality of dry EEG headsets compared to traditional gel-based systems in an unconstrained environment. EEG was used to collect Mobile Brain-body Imaging (MoBI) data from 432 people as they experienced an art exhibit in a public museum. The subjects were instrumented with either one of four dry electrode EEG systems or a conventional gel electrode EEG system. Each of the systems was evaluated based on the signal quality and usability in a real-world setting. First, we describe the various artifacts that were characteristic of each of the systems. Second, we report on each system's usability and their limitations in a mobile setting. Third, to evaluate signal quality for task discrimination and characterization, we employed a data driven clustering approach on the data from 134 of the 432 subjects (those with reliable location tracking information and usable EEG data) to evaluate the power spectral density (PSD) content of the EEG recordings. The experiment consisted of a baseline condition in which the subjects sat quietly facing a white wall for 1 min. Subsequently, the participants were encouraged to explore the exhibit for as long as they wished (piece-viewing). No constraints were placed upon the individual in relation to action, time, or navigation of the exhibit. In this freely-behaving approach, the EEG systems varied in their capacity to record characteristic modulations in the EEG data, with the gel-based system more clearly capturing stereotypical alpha and beta-band modulations.

    The Internet is rapidly changing the ways we communicate information around the globe today. The desire to provide Internet-based services to anyone, anywhere, anytime has brought satellite communications to the forefront to become an integral part of the Internet. In spite of the distances involved, satellite links are proving to be capable of providing Internet services based on Internet protocol (TCP/IP) stack. This development has led to the question particularly at NASA; can satellites and other space platforms become an Internet-node in space? This will allow the direct transfer of information directly from space to the users on Earth and even be able to control the spacecraft and its instruments. NASA even wants to extend the near earth space Internet to deep space applications where scientists and the public here on Earth may view space exploration in real time via the Internet. NASA's future solar system exploration will involve intensive in situ investigations of planets, moons, asteroids, and comets. While past missions typically involved a single fly-by or orbiting science spacecraft, future missions will begin to use fleets of small, highly intelligent robotic vehicles to carry out collaborative investigations. The resulting multi-spacecraft topologies will effectively create a wide area network spanning the solar system. However, this will require significant development in Internet technologies for space use. This paper provides the status'of the Internet for near earth applications and the potential extension of the Internet for use in deep space planetary exploration. The paper will discuss the overall challenges of implementing the space Internet and how the space Internet will integrate into the complex terrestrial systems those forms the Internet of today in a hybrid set of networks. Internet. We envision extending to the deep space environment such Internet concepts as a well-designed layered architecture. This effort will require an ability to

    This report describes the reduction and recycling technology of decommissioning concrete waste. Decontamination and decommissioning (D and D) becomes one of the most important nuclear markets especially in the developed countries including USA, UK and France where lots of the retired nuclear facilities have been waiting for decommissioning. In our country the KAERI has been carrying out the decommissioning of the retired TRIGA MARK II and III research reactors and an uranium conversion plant as the first national decommissioning project since 1998. One of the most important areas of the decommissioning is a management of a huge amount of a decommissioning waste the cost of which is more than half of the total decommissioning cost. Therefore reduction in decommissioning waste by a reuse or a recycle is an important subject of decommissioning technology development in the world. Recently much countries pay attention to recycle the large amount of concrete dismantling waste resulted from both a nuclear and a non nuclear industries. In our country, much attention was taken in a recycle of concrete dismantling waste as a concrete aggregate, but a little success has been resulted due to the disadvantages such as a weakness of hardness and surface mortar contamination. A recycle in nuclear industry and a self disposal of the radioactively contaminated concrete wastes are main directions of concrete wastes resulted from a nuclear facility decommissioning. In this report it was reviewed the state of art of the related technologies for a reduction and a recycle of concrete wastes from a nuclear decommissioning in the country and abroad. Prior to recycle and reuse in the nuclear sector, however, the regulatory criteria for the recycle and reuse of concrete waste should be established in parallel with the development of the recycling technology.

    A divertor concept for DEMO has been investigated at Karlsruhe Institute of Technology (KIT) which has to withstand a heat flux of 10 MW/m 2. The design utilizes small finger module composed of a small tungsten tile brazed on a thimble made from tungsten alloy. The divertor finger is cooled by helium jet impingement at 10 MPa and 600 °C. The subject of this paper is technological studies on machining and braze joining the divertor components. Goal of this task, which is considered an important R&D issue, is to find out appropriate manufacturing methods to ensure high functionality and high reliability of the divertor as well as to meet the economic aspect. One of the major requirements for manufacturing is micro-crack-free surface of tungsten parts, since crack propagations in tungsten were observed in the previous high-heat-flux tests at Efremov. Different manufacturing methods and the corresponding results are discussed in the following report.

    The general perception that the use of information technology (IT) in health care is ten to fifteen years behind IT in other industrial sectors such as banking, manufacturing, and airline is rapidly changing. Health care providers, faced with an unprecedented era of competition and managed care, are now exploring the opportunities for using IT to improve the quality while simultaneously reducing the cost of health care. A revolution is taking place in the health care industry, with IT playing an increasingly important role in its delivery. In recent years, for example, the industry spent approximately $12 billion to $14 billion a year on IT. Further exponential growth is expected as the health care industry implements electronic medical records, upgrades hospital information systems, sets up intranets for sharing information among key stakeholders, and uses public networks, such as the Internet, for distributing health-related information and for providing remote diagnostics. Along with these drastic changes and the new approach to health care, the field of health/medical informatics and telematics has also experienced significant growth in the last few years. This article identifies and surveys the critical information technologies that are being adopted to provide strategic benefits to the various health care constituencies including hospitals and health maintenance organizations (HMOs).

    The researches on engineering technology in the Mizunami Underground Research Laboratory (MIU) project consist of (1) development of design and construction planning technologies, (2) development of construction technology, (3) development of countermeasure technology, (4) development of technology for security and (5) development of technologies for restoration and/or reduction of the excavation damage. As a part of the second phase of the MIU project, research has been focused on the evaluation of engineering technologies including the initial design based on the data obtained during construction. In this research, examination of the plug applied to the future reflood test was conducted as a part of (5) development of technologies for restoration and/or reduction of the excavation damage relating to the engineering technology in the MIU (2014), specifically focused on (1) plug examination (e.g. functions, structure and material) and the quality control methods and (2) analytical evaluation of rock mass behavior around the plug through the reflood test. As a result, specifications of the plug were determined. These specifications should be able to meet requirements for the safety structure and surrounding rock mass against predicted maximum water pressure, temperature stress and seismic force, and for controlling the groundwater inflow, ensuring the access into the reflood gallery and the penetration performance of measurement cable. Also preliminary knowledge regarding the rock mass behavior around the plug after flooding the reflood gallery by installed plug was obtained. A CD-ROM is attached as an appendix. (J.P.N.)

    The purpose of this project is to measure the intermediate and long-term durability of vitrified waste forms developed by Lockheed Idaho Technology Co. (LITCO) for the immobilization of calcined radioactive wastes at Idaho National Engineering Laboratory. Two vitreous materials referred to as Formula 127 and Formula 532, have been subjected to accelerated durability tests to measure their long-term performance. Formula 127 consists of a glass matrix containing 5-10 vol % fluorite (CaF 2 ) as a primary crystalline phase. It shows low releases of glass components to solution in 7-, 28-, 70-, and 140-day Product Consistency Tests performed at 2000 m -1 at 90 degrees C. In these tests, release rates for glass-forming components were similar to those found for durable waste glasses. The Ca and F released by the glass as it corrodes appear to reprecipitate as fluorite. Formula 532 consists of a glass matrix containing 5-10 vol % of an Al-Si-rich primary crystalline phase. The release rates for components other than aluminum are relatively low, but aluminum is released at a much higher rate than is typical for durable waste glasses. Secondary crystalline phases form relatively early during the corrosion of Formula 532 and appear to consist almost entirely of the Al-Si-rich primary phase (or a crystal with the same Al:Si ratio) and a sodium-bearing zeolite. Future test results are expected to highlight the relative importance of primary and secondary crystalline phases to the rate of corrosion of Formula 127 and Formula 532

    Tests have been conducted at Argonne National Laboratory (ANL) in support of the efforts of Lockheed Idaho Technology Company (LITCO) to vitrify high-level waste calcines. Tests were conducted with three classes of LITCO glass formulations: Formula 127 (fluorine-bearing), Formula 532 (fluorine-free), and 630 series (both single- and mixed-alkali) glasses. The test matrices included, as appropriate, the Product Consistency Test Method B (PCT-B), the Materials Characterization Center Test 1 (MCC-1), and the Argonne vapor hydration test (VHT). Test durations ranged from 7 to 183 d. In 7-d PCT-Bs, normalized mass losses of major glass-forming elements for the LITCO glasses are similar to, or lower than, normalized mass losses obtained for other domestic candidate waste glasses. Formula 532 glasses form zeolite alteration phases relatively early in their reaction with water. The formation of those phases increased the dissolution rate. In contrast, the Formula 127 glass is highly durable and forms alteration phases only after prolonged exposure to water in tests with very high surface area to volume ratios; these alteration phases have a relatively small effect on the rate of glass corrosion. No alteration phases formed within the maximum test duration of 183 d in PCT-Bs with the 630 series glasses. The corrosion behavior of the mixed-alkali 630 series glasses is similar to that of 630 series glasses containing sodium alone. In VHTs, both single- and mixed-alkali glasses form zeolite phases that increase the rate of glass reaction. The original 630 series glasses and those based on a revised surrogate calcine formulation react at the same rate in PCT-Bs and form the same major alteration phases in VHTs

    Construction of artificial structures has caused a sediment process change due to the variation of hydraulic condition in Korea. Subsequently we have a serious problem of shoaling for shoreline deformation, siltation of the harbor and shipping channel. To protect those abnormal environmental changes, a large estimate has been spent for additional construction such as outer wall facilities, littoral nourishment and dredging. Systematic long-term studies should be carried out to understand the causes of environmental change. In addition, comprehensive plan is required for its monitoring and prevention. The radioisotope application studies for coastal environmental protection have not been actively performed only in the developed countries like France, Canada, and Australia etc., but also in many developing countries like Poland, India. Since KAERI has performed two experiments in costal area of Korea in 1960s, no more study has been reported. Recently the studies of radiotracer application technology is getting...

  15. Duplicating the fine art reproduction process: the technology used for guerilla ink-jet printing

    Accurate, automatic color reproduction is the goal of much of color technology. However, there is a need to improve reproduction in only the luminous or gray axis. Quadtone reproduction takes advantage of the four device CMYK color planes to provide greater gray-scale depth within the limitations of 8-bit per channel band-width. 'Quadtone' refers to photos reproduced using four tones of the same colorant. It is the printed imposition of four carefully selected shades of ink that result in a greater number of densities. Guerilla printing is a collection of algorithms using the CMYK channels to simulate traditional photography on an inkjet printer. Guerilla printing increases density values, defines detail and produces near continuous-tone screens.

    The current state and future trend of laser bio-cladding technology are discussed. Laser bio-cladding is used in implants including fabrication of metal scaffolds and bio-coating on the scaffolds. Scaffolds have been fabricated from stainless steel, Co-based alloy or Ti alloy using laser cladding, and new laser-deposited Ti alloys have been developed. Calcium phosphate bioceramic coatings have been deposited on scaffolds with laser to improve the wear resistence and corrosion resistence of implants and to induce bone regeneration. The types of biomaterial devices currently available in the market include replacement heart valve prosthesis, dental implants, hip/knee implants, catheters, pacemakers, oxygenators and vascular grafts. Laser bio-cladding process is attracting more and more attentions of people.

    Many different robotic systems have been developed for invasive medical procedures. In this article we will focus on robotic systems for image-guided interventions such as biopsy of suspicious lesions, interstitial tumor treatment, or needle placement for spinal blocks and neurolysis. Medical robotics is a young and evolving field and the ultimate role of these systems has yet to be determined. This paper presents four interventional robotics systems designed to work with MRI, CT, fluoroscopy, and ultrasound imaging devices. The details of each system are given along with any phantom, animal, or human trials. The systems include the AcuBot for active needle insertion under CT or fluoroscopy, the B-Rob systems for needle placement using CT or ultrasound, the INNOMOTION for MRI and CT interventions, and the MRBot for MRI procedures. Following these descriptions, the technology issues of image compatibility, registration, patient movement and respiration, force feedback, and control mode are briefly discussed. It is our belief that robotic systems will be an important part of future interventions, but more research and clinical trials are needed. The possibility of performing new clinical procedures that the human cannot achieve remains an ultimate goal for medical robotics. Engineers and physicians should work together to create and validate these systems for the benefits of patients everywhere. PMID:16754193

  20. Humanitarian Demining: Reality and the Challenge of Technology – The State of the Arts

    Full Text Available In the context of humanitarian demining it is essential to have a reliable and accurate sensor or an integration of heterogeneous/homogeneous sensors with efficient and reliable data fusion and processing techniques. In addition, it is necessary to overcome the constrain on the resources to speed up the demining process in terms of time, cost, and safety enhancement of personnel and operation. A portable handheld mine detection approach to sensor movement is slow and hazardous for individual deminers. Armored vehicles may not thoroughly protect the occupants and may be of only limited usefulness in off-road operations. Robotized solutions with effective sensing capabilities properly sized with suitable modularized mechanized structure and well adapted to local conditions of minefields can greatly improve the safety of personnel as well as work efficiency and flexibility. Such intelligent and flexible machines can speed the clearance and perform verifying processes when used in combination with handheld mine detection tools. Furthermore, the use of many robots working and coordinating their movement will improve the productivity of the overall mine detection process through the use of team cooperation and coordination. This paper evaluates the available mine clearance technologies and disscusses their development efforts and limitations to automate tasks related to demining process. In addition, it introduces technical features and design capabilities of a mobile platform needed to accelerate the demining process and achieve safety with cost effective measures.
