    This paper analyses the issue of how to bring school closer to students and how to tailor education to them so that they are able to present themselves to the world when they finish school, and communicate with it. The purpose of this study was to find the applicable reformist methods of teaching biology - methods that will make biology lessons look like creative workshops. For this purpose, nine semi-structured interviews with experienced teachers of biology were conducted. UNESCO's Conferen...

  2. Fuel cells for vehicle applications in cars - bringing the future closer

    Science.gov (United States)

    Panik, Ferdinand

    Among all alternative drive systems, the fuel cell electric propulsion system has the highest potential to compete with the internal combustion engine. For this reason, Daimler-Benz AG has entered into a co-operative alliance with Ballard Power Systems, with the objectives of bringing fuel cell vehicles to the market. Apart from the fuel cell itself, fuel cell vehicles require comprehensive system technology to provide fuel and air supply, cooling, energy management, electric and electronic functions. The system technology determines to a large extent the cost, weight, efficiency, performance and overall customer benefit of fuel cell vehicles. Hence, Daimler-Benz and Ballard are pooling their expertise in fuel cell system technology in a joint company, with the aim of bringing their fuel cell vehicular systems to the stage of maturity required for market entry as early as possible. Hydrogen-fuelled zero-emission fuel cell transit `buses' will be the first market segment addressed, with an emphasis on the North American and European markets. The first buses are already scheduled for delivery to customers in late 1997. Since a liquid fuel like methanol is easier to handle in passenger cars, fuel reforming technologies are developed and will shortly be demonstrated in a prototype, as well. The presentation will cover concepts of fuel cell vehicles with an emphasis on system technology, the related testing procedures and results as well as an outline of market entry strategies.

  3. Bringing Planet Finder Closer: 1AU missions for Terrestrial Planet Finder, precursor and follow-on

    Woolf, N. J.

    1997-12-01

    A mission to search for Earth-like planets and obtain their spectra was set at 5AU because the zodiacal dust emission at 1AU would make larger mirrors necessary. When the concept was developed in 1995, the Space Telescope with a 2.4m mirror cost \\2 billion. To ask for even larger mirrors on a mission seemed unrealistic. Now, Next Generation Space Telescope with a 6-8m glass membrane primary from the Mirror Lab seems achievable within budget, and a 1 AU Terrestrial Planet Finder mission with only half as much glass could be made at no greater cost. The advantages of a 1 AU mission are (1) further IR detector development would no longer be needed; (2) cryogens in dewars would last long enough; (3) for 1AU/5AU systems matched in performance for 15pc planets, the 1AU system would allow higher spectral resolution for closer planetary systems, possibly permitting detection of methane; (4) the signal /noise for a 1AU system will deteriorate less when a planetary system with strong exo-zodiacal emission is encountered; (5) neither RTGs nor large solar cell arrays are needed; (6) mass is less constrained. A precursor mission to confirm TPF techniques at lower cost, and study giant planets at 5\\mu$ could also operate at 1AU. A follow on mission to obtain high resolution spectra of exo-planetary atmospheres would not benefit appreciably from 5AU operation. A 1AU mission would be fine for it.

  4. Bringing a Global Issue Closer to Home: The OSU Climate Change Webinar Series

    2012-12-01

    When people think about the effects of climate change, many will still picture that iconic lone polar bear clinging to a shrinking iceberg in Antarctica. But many don't realize that the impacts that we will face here at home could also be severe, directly affecting the food we eat, the health we have, and the natural environments we appreciate. To help better explain and ultimately localize those impacts for Great Lakes residents, 10 departments within Ohio State University partnered in 2009 to create the Global Change, Local Impact webinar series. The monthly series brings in experts from around the Great Lakes region to discuss issues and impacts we will encounter regionally as our climate changes. Originally designed as a small series for Ohioans, the series has broadened to focus on Great Lakes-related issues, with more than 4,500 attendees representing 500 organizations in governmental agencies, academia, non-profit groups, private industry, and the legislature from around the country. Over the past two years, the OSU Climate Team expanded its educational reach by partnering with external groups like the Centers for Disease Control and Prevention, Great Lakes Regional Water Program, National Oceanic and Atmospheric Administration, and the Great Lakes Sea Grant Network to help deliver the most knowledgeable experts and resources for each Great Lake-focused climate topic and archive those resources on its www.changingclimate.osu.edu web site. As a result of these collaborative efforts, participants say the webinars are one of their primary resources for climate-related research information in the region, with 80-90% polled saying they use this information as an unbiased resource to help not only understand how climate change could affect local concerns like public health, agriculture, and infrastructure, but what they in their vocations and daily lives can do to prepare for it. For scientists and practitioners, this series serves as the perfect low carbon venue

    @@ The China-UK Systems Biology Workshop 2005 was held during June 20-21 in the National Science Park of Zhejiang University, Hangzhou, China. It was organized by the Institute of Bioinformatics, Zhejiang University, and was initiated by Prof. Dr. Jun Zhu (Zhejiang University) and Prof. Dr. John Findlay (University of Leeds, UK). The workshop was part of the program called UK-China Partners in Science, a one-year campaign that was initiated by the British government to explore more collaborations between UK and China on science and technology. It was attended also by a representative of this program, Mr.Frank Yuan, senior science & innovation officer. The idea of the workshop was to bring together experts with specialists in systems biology in order to promote the "natural partnership" between scientists from the two countries. The most important items of systems biology considered at the workshop were: (1) New technologies and advances in systems biology; (2) Research developments in genomics and proteomics; (3) New methodologies and software in computational biology; (4) Research collaboration on systems biology between China and UK.

  7. Raised Relief Mars Globe Brings the Red Planet Closer

    Science.gov (United States)

    2006-01-01

    The Mars Globe 20x is the first digitally produced raised relief globe to be sold at retail establishments. The rises and dips of the Martian landscape have been multiplied by 20 to make the shapes more noticeable to human touch and sight. They make this globe, with its over 1 million elevation points, a visually stunning introduction to the planet. Spectrum 3D used the NASA digital land elevation data to aim lasers that then shaped and defined the master globe s surface. Subsequent copies were then made by creating a master globe mold. The molded copies are hand finished by workers who remove errant edges or lines that may appear on the raw globes and then paint the surfaces. The result is a globe that measures in at 18 inches in diameter, roughly 1:15,729,473 scale of the actual planet. The exaggerated raised relief is like having a 3-D digital microscope for planetary shapes. This makes the landmarks easier to learn and understand, as it provides easy visuals for orientation. People have a natural propensity for understanding 3-D shapes more easily than numbers or words. The 3-D globes appeal to both the kinetic and visual learning aspects of the brain, making it easy for people to readily memorize the landmarks and to make a mental model that they will remember for a long time.

  8. Bringing Model Checking Closer to Practical Software Engineering

    CERN Document Server

    AUTHOR|(CDS)2079681; Templon, J A; Willemse, T.A.C.

    Software grows in size and complexity, making it increasingly challenging to ensure that it behaves correctly. This is especially true for distributed systems, where a multitude of components are running concurrently, making it dicult to anticipate all the possible behaviors emerging in the system as a whole. Certain design errors, such as deadlocks and race-conditions, can often go unnoticed when testing is the only form of verication employed in the software engineering life-cycle. Even when bugs are detected in a running software, revealing the root cause and reproducing the behavior can be time consuming (and even impossible), given the lack of control the engineer has over the execution of the concurrent components, as well as the number of possible scenarios that could have produced the problem. This is especially pronounced for large-scale distributed systems such as the Worldwide Large Hadron Collider Computing Grid. Formal verication methods oer more rigorous means of determining whether a system sat...

  9. Multiple-case depth research: bringing experience-near closer.

    Science.gov (United States)

    Schneider, K J

    1999-12-01

    The term "experience-near" has become associated with a variety of alternatives to mainstream clinical research. These alternatives converge on one basic methodological goal-faithfulness to clinical phenomena as lived. This article presents one approach to lived clinical phenomena that I term multiple-case depth research or MCDR. MCDR is a novel and highly sensitive methodology that combines both in-depth case investigation with experiential therapeutic principles. To illustrate the power of MCDR, I present a hypothetical process and outcome study involving three client cohorts (those who undergo respectively cognitive-behavioral therapy, intersubjective psychoanalytic therapy, and existential-humanistic therapy). I detail the structure of this hypothetical study, the steps by which it proceeds, and the yield that it portends. I conclude that, if conducted properly, MCDR can provide rich, valid, and unprecedented insight into effective psychotherapy.

    Full Text Available Throughout the world, and for many decades, science-rich cultural institutions, such as zoos, aquaria, museums, and others, have collaborated with schools to provide students, teachers and families with opportunities  to expand their experiences and understanding of science. Programmes include supplementary classroom experiences; integrated core academic curricula; student science learning communities located in afterschool, summer, and weekend programmes; teacher professional development opportunities and communities; and even district infrastructure efforts around issues such as standards and assessment development or teacher preparation. Throughout the world, thesecollaborations have allowed students, and also teachers, to explore, understand, and care about a wide range of natural settings, phenomena, and cultural and historical objects. They have helped students to notice, consider, and investigate relationships between human social behavior and environmental consequences. They have  provided contexts, materials, rationales, and support for students and teachers to engage deeply in scientific inquiry processes of learning. These experiences—with an array of real-life settings, plants, animals, professional science communities, objects, scientific instrumentation, and current research and data—have been shown to spark curiosity, generate questions, and lead to a depth of understanding andcommitment in ways that are often less possible when the same material is encountered in books or on screens. This paper draws on theoretical perspectives as well as practical examples, focusing on inquiry-based science education, to show that formal-informal collaborations fall within the core activities  of both schools and organisations working in informal contexts including museums, youth programmes, and libraries. The paper argues that what is needed are more intentional and strategic deployments of resources, leading to collaborations that build on the particular affordances and strengths of different institutional types to meet shared goals  of making science learning more accessible and compelling to young people in our communities.

    2012-01-01

    Signed graphs, i.e., undirected graphs with edges labelled with a plus or minus sign, are commonly used to model relationships in social networks. Recently, Kermarrec and Thraves initiated the study of the problem of appropriately visualising the network: They asked whether any signed graph can be embedded into the metric space R^l in such a manner that every vertex is closer to all its friends (neighbours via positive edges) than to all its enemies (neighbours via negative edges). Interestingly, embeddability into R^1 can be expressed as a purely combinatorial problem. In this paper we pursue a deeper study of this particular case, answering several questions posed by Kermarrec and Thraves. First, we refine the approach of Kermarrec and Thraves for the case of complete signed graphs by showing that the problem is closely related to the recognition of proper interval graphs. Second, we prove that the general case, whose polynomial-time tractability remained open, is in fact NP-complete. Finally, we provide lo...

  7. Bringing Gravity to Space

    Norsk, P.; Shelhamer, M.

    2016-01-01

    This panel will present NASA's plans for ongoing and future research to define the requirements for Artificial Gravity (AG) as a countermeasure against the negative health effects of long-duration weightlessness. AG could mitigate the gravity-sensitive effects of spaceflight across a host of physiological systems. Bringing gravity to space could mitigate the sensorimotor and neuro-vestibular disturbances induced by G-transitions upon reaching a planetary body, and the cardiovascular deconditioning and musculoskeletal weakness induced by weightlessness. Of particular interest for AG during deep-space missions is mitigation of the Visual Impairment Intracranial Pressure (VIIP) syndrome that the majority of astronauts exhibit in space to varying degrees, and which presumably is associated with weightlessness-induced fluid shift from lower to upper body segments. AG could be very effective for reversing the fluid shift and thus help prevent VIIP. The first presentation by Dr. Charles will summarize some of the ground-based and (very little) space-based research that has been conducted on AG by the various space programs. Dr. Paloski will address the use of AG during deep-space exploration-class missions and describe the different AG scenarios such as intra-vehicular, part-of-vehicle, or whole-vehicle centrifugations. Dr. Clement will discuss currently planned NASA research as well as how to coordinate future activities among NASA's international partners. Dr. Barr will describe some possible future plans for using space- and ground-based partial-G analogs to define the relationship between physiological responses and G levels between 0 and 1. Finally, Dr. Stenger will summarize how the human cardiovascular system could benefit from intermittent short-radius centrifugations during long-duration missions.

    `I'm doing a physics that is pulling me towards it.' `I like the course being more up to date.' `You learn the physics but you also think ``well I actually see a point in knowing this physics''.' `This course presents physics in a more interesting way as it focuses on practical activity and applications of physics.' `The industrial visit gives students the opportunity to look for science in action.' These are just some of the comments from students and teachers piloting the new Salters Horners Advanced Physics course (SHAP). Contexts and applications drive the course, providing interest and motivation for students and alerting them to some of the many career areas that involve physics. For example, the operation of a CD player leads to a study of waves and superposition; archaeological surveying and analysis brings in d.c. circuitry and x-ray diffraction; consideration of safety in rail transport involves learning about mechanics and electromagnetism. The course is produced by a team directed from the University of York and funded by a consortium of industrial and charitable sponsors. It is examined by Edexcel and support materials are published by Heinemann. The pilot, involving some 50 centres, began in September 1998 with the new subject core and the AS qualification intermediate between GCSE and the full A-level standard. The course has been fully approved by QCA, and from September 2000 it will be open to all. For comprehensive information about SHAP, visit the project's website: www.york.ac.uk/org/seg/salters/physics . Pilot materials for students, teachers and technicians are available from Heinemann. They will be re-edited and published in full colour for September 2000. Members of the team will attend the annual ASE meeting in Leeds this month; there will be a talk and a hands-on workshop where student activities can be sampled. Materials will be on view at the University of York stand. In addition, Edexcel and the York team are running a series of

    2008-01-01

    Fifty years ago when only BOD was removed at municipal WWTPs primary clarifiers were designed with 2-3 hours hydraulic retention time (HRT). This changed with the introduction of nitrogen removal in activated sludge treatment that needed more BOD for denitrification. The HRT of primary clarification was reduced to less than one hour for dry weather flow with the consequence that secondary sludge had to be separately thickened and biogas production was reduced. Only recently the ammonia rich digester liquid (15-20% of the inlet ammonia load) could be treated with the very economic autotrophic nitritation/anammox process requiring half of the aeration energy and no organic carbon source compared to nitrification and heterotrophic denitrification. With the introduction of this new innovative digester liquid treatment the situation reverts, allowing us to increase HRT of the primary clarifier to improve biogas production and reduce aeration energy for BOD removal and nitrification at similar overall N-removal.

    2011-12-21

    We introduce a novel siloxane-terminated solubilizing group and demonstrate its effectiveness as a side chain in an isoindigo-based conjugated polymer. An average hole mobility of 2.00 cm 2 V -1 s -1 (with a maximum mobility of 2.48 cm 2 V -1 s -1), was obtained from solution-processed thin-film transistors, one of the highest mobilities reported to date. In contrast, the reference polymer with a branched alkyl side chain gave an average hole mobility of 0.30 cm 2 V -1 s -1 and a maximum mobility of 0.57 cm 2 V -1 s -1. This is largely explained by the polymer packing: our new polymer exhibited a π-π stacking distance of 3.58 Å, while the reference polymer showed a distance of 3.76 Å. © 2011 American Chemical Society.

    Miocene baleen whales were highly diverse and included tens of genera. However, their taxonomy and phylogeny, as well as relationships with living whales, are still a subject of controversy. Here, "Mesocetus" argillarius, a poorly known specimen from Denmark, is redescribed with a focus on the cranial anatomy. It was found to represent not only a new genus, Tranatocetus gen. nov., but also a new family; Tranatocetidae. The whales of this family have the rostral bones either overriding or dividing the frontals; the rostral bones are contacting the parietals and nasals dividing the maxillae on the vertex; the occipital shield is dorsoventrally bent. The tympanic bulla is particularly characteristic of this family featuring a short, narrow anterior portion with a rounded or squared anterior end and a wider and higher posterior portion that is swollen in the posteroventral area. A phylogenetic analysis including 51 taxa supports a monophyletic group comprising most Neogene and modern whales, with Tranatocetidae being possibly closer related to Balaenopteridae (rorquals) than to Cetotheriidae. Tranatocetidae exhibit a charahteristic bulla shape. In fact, all Neogene and modern mysticete families examined have a unique shape of the tympanic bulla that is diagnostic at family-level. Inclusion of problematic taxa like Tranatocetus argillarius in phylogenies brings new understanding of the distribution and diagnostic value of character traits. This underlines the need for re-examination of earlier described specimens in the light of the wealth of new information published in later years.

  16. Impact of replacement of conventional Recloser with PulseCloser

    Directory of Open Access Journals (Sweden)

    Olgert Metko

    2011-04-01

    Full Text Available Conventional recloser stresses the circuit with current fault every time they reclose into a fault. After clearing a fault, a conventional recloser simply recloses the interrupters to continuously test the presence of the fault. If the fault is still there, the interrupters are tripped again. Then, after a time delay, the interrupters are reclosed. During reclosing operation of Automatic Recloser, including the faster recloser one, powerful transient processes occurs and significant amount of energy is feeding the fault, resulting in system-damaging and voltage sags. Replacing conventional recloser with PulseCloser one minimizes these effects and creates the possibility to use multiple reclosing even when traditional autoreclosing can not be allowed.PulseCloser Technology drastically reduces overcurrent stress on the system. Once the PulseCloser interrupts a fault, it sends the impulses to intelligently tests for current fault before reclosing. The relative let-through energy of a pulseclosing operation is typically less than 2% of a conventional reclosing operation. Pulseclosing is superior to conventional reclosing. It greatly reduces stress on system components as well as voltage sags experienced by customers’ upstream fault.This paper analyzes transient processes during simulation of operation of traditional recloser and PulseCloser type. Simulations are performed using ATP software. The simulations show the remarkable difference in current versus time during fault testing in the transmission line equipped with conventional recloser and PulseCloser. The analysis justifies the replacement of Conventional Recloser with PulseCloser one.

    Have you ever heard of “BYOD”? No, it is not a pop band. Try again. It is short for “Bring Your Own Device” (the French use “AVEC” -  “Apporter Votre Equipement personnel de Communication”) and describes an option long since offered at CERN: the possibility to bring along your personal laptop, smartphone or PDA, use it on CERN premises and connect it to the CERN office network. But hold on. As practical as it is, there is also a dark side.   The primary advantage, of course, is having a digital work environment tuned to your needs and preferences. It allows you to continue working at home. Similarly, you always have your music, address books and bookmarks with you. However, as valuable as this is, it is also a responsibility.

  2. Wishful seeing: more desired objects are seen as closer.

    Science.gov (United States)

    Balcetis, Emily; Dunning, David

    2010-01-01

    Although people assume that they see the surrounding environment as it truly is, we suggest that perception of the natural environment is dependent upon the internal goal states of perceivers. Five experiments demonstrated that perceivers tend to see desirable objects (i.e., those that can fulfill immediate goals-a water bottle to assuage their thirst, money they can win, a personality test providing favorable feedback) as physically closer to them than less desirable objects. Biased distance perception was revealed through verbal reports and through actions toward the object (e.g., underthrowing a beanbag at a desirable object). We suggest that seeing desirable objects as closer than less desirable objects serves the self-regulatory function of energizing the perceiver to approach objects that fulfill needs and goals.

    Both populous and fast-growing, China and India share important similarities. Over the years, comparative studies on both countries, especially in terms of economic development, have become a hot topic around the world. China and India issues have aroused intense attention and interest in international academia. Three articles in this issue examine the race between the dragon and the elephant in the arena of economic development, information industry and software. In his article "A closer look at Chinese and Indian economic development," Prof. Huang Qunhui compares China and India’s economic development from national strategic perspectives based on his first-hand research; in "What China and India can learn from each other in the information industry?" Prof. Shen Kaiyan undertakes a comparative analysis of the development of information industries in China and India; lastly, Prof.Fang Hong’s empirical study looks at competition and cooperation in the Chinese and Indian software industries. This selection of essays begins with overall economic development, moves to a closer examination of the information industry, and then concludes with a look at the software industry, giving us an extremely broad yet also detailed comparison of the economies of these two emerging giants.

  8. OT promotes closer interpersonal distance among highly empathic individuals.

    Perry, Anat; Mankuta, David; Shamay-Tsoory, Simone G

    2015-01-01

    The space between people, or 'interpersonal distance', creates and defines the dynamics of social interactions and is a salient cue signaling responsiveness and feeling comfortable. This distance is implicit yet clearly felt, especially if someone stands closer or farther away than expected. Increasing evidence suggests that Oxytocin (OT) serves as a social hormone in humans, and that one of its roles may be to alter the perceptual salience of social cues. Considering that empathic ability may shape the way individuals process social stimuli, we predicted that OT will differentially affect preferred interpersonal distance depending on individual differences in empathy. Participants took part in two interpersonal distance experiments: In the first, they had to stop a (computer visualized) protagonist when feeling most comfortable; in the second, they were asked to choose the room in which they would later discuss intimate topics with another. Both experiments revealed an interaction between the effect of OT and empathy level. Among highly empathic individuals, OT promoted the choice of closer interpersonal distances. Yet, OT had an opposite effect on individuals with low empathic traits. We conclude that the enhancement of social cues following OT administration may have opposite effects on individuals with different empathic abilities. PMID:24509491

    In this paper we depart from neoclassical assumptions of fully competitive energy markets, and attempt to represent an oligopolistic market, which is closer to reality than a fully competitive environment given the reconsolidation tendencies of energy companies. We focus mainly on the effects of energy policies for energy efficiency improvement, namely on supplier obligations and White Certificates in an oligopoly market. In particular we concentrate on two of the most common oligopolistic models: the Cournot and the Stackelberg model where agents are assumed to strategically interact (unlike perfect competition where firms behave atomistically). In these two game theoretically based models the behaviour of each market actor is based on a detailed decision tree, which determines the optimal move given the expectations on the competitor's strategy. According to our preliminary findings, the price of electricity is always higher under the symmetric Cournot model than the Stackelberg one, but the introduction of white certificate obligations should encompass larger increases in the electricity prices in a Stackelberg game. In order to test our theoretical findings we make use of a typical oligopolistic market in Italy, where we depict that a leader company can serve the main part of electricity and energy efficiency projects, through financing them with White Certificates, while the residual demand is more expensive and must be covered at a high cost from follower companies.

    One major element of EU's external energy policy is expanding its energy norms and regulations to neighbourhood countries and beyond to achieve its energy policy priorities - safe, secure, affordable and sustainable energy supply. The importance of external energy policy has been acknowledged in the European Union's 2007 'energy package', and Second Strategic Energy Review and the European Commission's Communication on security of energy supply and international cooperation. The EU Renewable Energy Directive provides another element to crossborder cooperation by allowing Member States to fulfil their 2020 renewable energy (RES) targets by implementing joint projects in third countries. Even though the Member States' national renewable energy action plans (NREAPs) to reach their RES targets do not indicate any significant use of this mechanism, the RES Directive acknowledges the importance of renewable energy as part of external energy policy. This report aims at presenting the political framework between the EU and the BETTER project target regions (North Africa, Western Balkans and Turkey) with regards to (renewable) energy and the relevant initiatives and the projects to set the scene for RES joint projects as defined in Article 9 of the RES Directive. The main objectives of this study report are (1) to review energy treaties, agreements, and partnerships to assess their relevance to cooperation mechanism with Third countries; and (2) to analyse the relevance of the recent projects and initiatives to BETTER project and improve and trigger the communication and synergies between BETTER project partners and the relevant projects.

    GSM-R, the digital radio communication system for railways, offers a uniform standard, which more and more railways throughout Europe are using. GSM-R is thus making a crucial contribution to bringing the railway systems closer together. The network operators are already cooperating with one another internationally at various levels in Europe with this aim in mind. The UIC's working groups have drawn up a standardised contract for setting up international roaming, but there are still numerous hurdles to overcome, despite the very considerable volume of work already done. In this context, it would be helpful if certifications of the individual GSM-R networks and their operating methods could be introduced in a binding fashion in accordance with the example laid down ISO 9002. New interfaces between the radio-equipment systems are coming into being at the border crossings between neighbouring infrastructure managers, where there has to be an adequately dimensioned overlapping zone between the networks, and switching from one network to another must be determined independently of the operational constraints of the particular border sections. Thanks to GSM-R, it is becoming possible in many instances to eliminate the communication gaps that have existed to date in handling train movements across borders and thus to make a contribution to the desired improvement in interoperability and operating control. In doing this, it is important above all else for the railway employees to feel at ease working with such systems too. (orig.)

A tremendous effort ensued to find and capture the individuals who were responsible or associated with these events. Many of the individuals who were captured have remained imprisoned for an indefinite amount of time due to the political debate regarding what is the most appropriate venue to try suspecgts arrested and charged with acts of terrorism. The choices come down to trial either by a trial by a Military Commission or a U.S. Federal District Court. There are unique challenges for effective prosecution in both venues. Which venue the Obama Administration will deem appropriate to try the terrorists captured by the former administration remains uncertain at this point in time.

    None of the in-vitro and in-vivo methods listed permits on unambiguous diagnosis when applied alone, owing to the fact that similar or even identical findings are obtained for various individual parameters in different thyroid diseases. Further, especially the in-vitro tests are also subject to extrathyroidal effects which may mask the typical findings. The limited and varying specificity and sensitivity of the tests applied, as well as the falsification of results caused by the patients' idiosyncracies and the methodology, make it necessary to interpret and evaluate the in-vivo and in-vitro findings only if the clinical situation (anamnesis and physical examination) is known. For maximum diagnostic quality of the tests, the initial probability of the assumed type of thyroid disease must be increased (formulation of the clinical problem). The concepts of exclusion diagnosis and identification must be distinguished as well as the diagnosis of functional disturbances on the one hand and of thyroid diseases on the other. Both of this requires a qualified, specific and detailed anamnesis and examination procedure, and the clinical examination remains the obligatory basis of clinical diagnostics. In case of inexplicable discrepancies between the clinical manifestations and the findings obtained with specific methods, or between the findings obtained with a specific method, the patient should be referred to an expert institution, or the expert institution should be consulted.

Although it is often stated as a long-term goal of science outreach programs, in practice there are many barriers to research in the school setting, among them increasing emphasis on test-oriented training, decreasing interest and participation in science fairs, limited teacher confidence and experience for mentoring research, insufficient student preparedness for research projects, and the short term of university involvement (typically limited to brief one-day encounters). For the past three+ years we have tried to address these issues through a focused outreach program we have called the PEPP Research Fellows Program. This is treated as an honors program in which high school teachers in our group nominate students with interests in science careers. These students are invited to participate in the program, and those who elect to take part participate in a one-day education and training session in the fall. Rather than leave research projects completely open, we direct the students at toward one of two specific, group-oriented projects (in our case, one focusing on local recordings of mining explosions, and a second on teleseismic body-wave analysis), but we encourage them to act as independent researchers and follow topics of interest. The students then work on seismic data from the local educational network or from the IRIS facilities. Following several months of informal interaction with teachers and students (email, web conferencing, etc.), we bring the students and teachers to our university for a weekend research symposium in the spring. Students present their work in oral or poster form and prizes are given for the best papers. Projects range from highly local projects (records of seismic noise at school X) to larger-scale regional projects (analysis of teleseismic P-wave delays at PEPP network stations) From 20 to

  16. Poster power brings together electronics community

    CERN Multimedia

    2006-01-01

    An 'Electronics at CERN' poster session was displayed on the mezzanine in building 500 for two days from 30 November. The display consisted of 20 posters and brought together a wide range of electronic projects designed and assembled by CERN teams and other collaborators involved in the building of the LHC. This was the first time this event had been held. As its organiser John Evans (IT/DES) explained, 'the idea came from the experience of attending conferences outside CERN, where you may find projects from CERN you didn't know about. It's nice to bring them together so we can all benefit from the efforts made.' The work on show spanned different departments and experiments, ranging from microelectronics to equipment designed for giant magnets. The invited audience was equally broad and included engineers, physicists as well as the electronics community at CERN. An informal gathering of all the exhibitors also offered an opportunity to view and discuss the work over a cup of coffee. 'The poster session acts...

  17. Bringing Reflections into the TEFL Classrooms

    2002-01-01

    Full Text Available Abstract: Reflective practice is defined by John Dewey as a proactive, ongoing examination of beliefs and practices, their origins and impacts. In the reflective practice, the teacher and learners are engaged in a continuous cycle of self-observation and self-evaluation in order to understand their own actions and reactions, and thereby develop the teaching-learning process on an on-going basis. While English is regarded as compulsory in the preparation of more qualified human resources for the country, there are still complaints about the low English mastery of the majority of secondary and tertiary education graduates in Indonesia. It seems likely that bringing the reflective practice in the TEFL classrooms will help improve the teaching-learning of English in a more caring and responsive manner. It is expected that this will not only improve the English mastery, but also develop personal talents and capacities of the learners. The features of reflective practice in TEFL and their advantages for personal and professional development will be further discussed.

    “They shall beat their swords into plowshares, and their spears into pruning hooks. Nation shall not lift up sword against nation. Neither shall they learn war anymore." So says Isaiah 2:4, as transcribed on the famous wall in Ralph Bunche park, just the other side of 1st Avenue from the UN’s New York headquarters, where we held a celebration of our 60th anniversary year on Monday 20 October. I used the quotation in my opening address, since it is such a perfect fit to the theme of 60 years of science for peace and development.   The event was organised with the United Nations Economic and Social Council, ECOSOC, in the framework of CERN’s observer status at the UN, and although focused on CERN, its aim was broader. Presentations used CERN as an example to bring out the vital importance of science in general to the themes of peace and development. The event was presided over by Martin Sajdik, President of ECOSOC, and we were privileged to have presentat...

  20. Integrated system brings hospital data together.

    Science.gov (United States)

    Johnson, K F

    1987-10-01

    Healthcare industry changes during the 1980s--increased competition and alterations in the Medicare payment methodology--place new and more complex demands on a hospital's information systems, which often fall short of meeting those demands. These systems were designed for financial reporting, billing, or providing clinical data, and few of them are capable of linking with other unrelated systems. Today's hospital manager needs timely and simultaneous access to data from a variety of sources within the hospital. All the elements to accomplish this are collected somewhere in the hospital, but finding them and bringing them together is difficult. The key to the efficient management and use of data bases is in understanding the fundamental concept of relational data bases, which is the capability of linking or joining separate data files through a common data element in each file. In this way, data files may be integrated into a "related" data base. Any number of separate files, or tables, may exist within a "relational" data base as long as a series of threads links them. A strategic management information data base includes the information necessary to analyze, understand, and manage the hospital's markets, products, resources, and profitability. The major components of this information system are the case mix and cost accounting, budgeting, and modeling systems. The case mix and cost accounting factors involve managing concrete pieces of data, whereas the budgeting and modeling factors manipulate data to create a scenario. The strategic management information data base is the foundation of a hospital's decision support system, which is rapidly moving into the category of a necessary tool of the hospital manager's trade.

  1. Bringing the Unidata IDV to the Cloud

    2015-12-01

    Maintaining software compatibility across new computing environments and the associated underlying hardware is a common problem for software engineers and scientific programmers. While traditional software engineering provides a suite of tools and methodologies which may mitigate this issue, they are typically ignored by developers lacking a background in software engineering. Causing further problems, these methodologies are best applied at the start of project; trying to apply them to an existing, mature project can require an immense effort. Visualization software is particularly vulnerable to this problem, given the inherent dependency on particular graphics hardware and software API's. As a result of these issues, there exists a large body of software which is simultaneously critical to the scientists who are dependent upon it, and yet increasingly difficult to maintain.The solution to this problem was partially provided with the advent of Cloud Computing; Application Streaming. This technology allows a program to run entirely on a remote virtual machine while still allowing for interactivity and dynamic visualizations, with little-to-no re-engineering required. When coupled with containerization technology such as Docker, we are able to easily bring the same visualization software to a desktop, a netbook, a smartphone, and the next generation of hardware, whatever it may be.Unidata has been able to harness Application Streaming to provide a tablet-compatible version of our visualization software, the Integrated Data Viewer (IDV). This work will examine the challenges associated with adapting the IDV to an application streaming platform, and include a brief discussion of the underlying technologies involved.

  2. Mitigation diagnostics

    International Nuclear Information System (INIS)

    This paper reports that experience in the remediation of schools and other large buildings has shown the importance of the effects of both the location of geologic sources and HVAC-induced distribution of indoor radon. In general, elevated radon in areas of schools with evenly distributed HVAC pressures are correlated with maximum soil radon emanations. However, strong or unequal HVAC effects can redistribute indoor radon to areas away from the direct source. Effective remediation required a complete understanding of both contributions. In some schools, highest indoor radon levels were located near large return ducts and were attributed to proximity to negative HVAC pressure. Successful sub-slab depressurization systems were installed, however, in rooms with lower indoor but greatest sub-slab radon levels, closest to the source. This shows the inadequacy of using indoor radon levels alone as a basis for remediation. Wings of two other schools with radon problems have equivalent window fan coil units in rooms of equal size and no central HVAC system. Highest indoor radon levels correlated well with highest sub-slab radon levels due to the equivalent effects of the window units. Diagnostic tests in other schools have revealed: blockwall radon transport to upper floors; high blockwall radon adjacent to sub-slab sources; and elevated indoor radon over crawlspace being drawn upward by HVAC-induced negative pressure, determined from indoor to outdoor micromanometer measurements

    Full Text Available Diagnostic thoracoscopy in patients with pleural effusion of unclear origin mostly provides the correct diagnosis. Results from published reports of previous researches are not uniform. In 47 male and 20 female patients with pleural effusion of unknown etiology, after receiving negative results obtained from cytological finding of pleural effusion and percutaneous needle biopsy, thoracoscopy with biopsy of one or both pleurae was performed. Procedure was done in local anesthesia using Stortz rigid thoracoscope. In 37 patients with malignant disease (primary or metastatic diagnosis was confirmed histopathologically in 31 patient (81.12%. In 27 patients with inflammatory pleural disease diagnosis was confirmed histopathologically in 22 patients (81.4%. Among 11 patients with specific pleural effusions, tuberculosis was confirmed in 10 (90.91%. Normal finding in cases of spontaneous pneumothorax and pulmonary embolism was taken as a positive result. Total number of positive findings was 55 (82.10%. In one patient, the third spontaneous pneumothorax was the indication for thoracoscopy, and after numerous bullae were seen during the procedure, talcum powder pleurodesis was done. In four patients low intensity subcutaneous emphysema occurred one day after thoracoscopy. It can be concluded that thoracoscopy in local anesthesia out of the operating room is good and practical method for solving the unclear pleural effusions, with neglectable rate of complications.

  4. Smart Technology Brings Power to the People

    2006-12-01

    Imagine you’re at home one Saturday morning on the computer, as your son takes a shower, your daughter is watching TV, and a load of laundry is in your washer and dryer. Meanwhile, the fragrance of fresh-brewed coffee fills the house. You hear a momentary beep from the dryer that tells you that if you were to look, a high-energy price indicator would be displayed on the front panels of some of your favorite appliances. This tells you that you could save money right now by using less energy. (You’ve agreed to this arrangement to help your utility avoid a substation upgrade. In return, you get a lower rate most of the time.) So you turn off some of the unneeded lights in your home and opt to wait until evening to run the dishwasher. Meanwhile, some of your largest appliances have automatically responded to this signal and have already reduced your home’s energy consumption, saving you money. On January 11, 2006, demonstration projects were launched in 200 homes in the Pacific Northwest region of the United States to test and speed adoption of new smart grid technologies that can make the power grid more resilient and efficient. Pacific Northwest National Laboratory, a U.S. Department of Energy national laboratory in Richland, Washington, is managing the yearlong study called the Pacific Northwest GridWise™ Testbed Demonstration, a project funded primarily by DOE. Through the GridWise™ Demonstration projects, researchers are gaining insight into energy consumers’ behavior while testing new technologies designed to bring the electric transmission system into the information age. Northwest utilities, appliance manufacturers and technology companies are also supporting this effort to demonstrate the devices and assess the resulting consumer response. A combination of devices, software and advanced analytical tools will give homeowners more information about their energy use and cost, and we want to know if this will modify their behavior.

    2013-04-01

    People routinely remember events that have passed and imagine those that are yet to come. The past and the future are sometimes psychologically close ("just around the corner") and other times psychologically distant ("ages away"). Four studies demonstrate a systematic asymmetry whereby future events are psychologically closer than past events of equivalent objective distance. When considering specific times (e.g., 1 year) or events (e.g., Valentine's Day), people consistently reported that the future was closer than the past. We suggest that this asymmetry arises because the subjective experience of movement through time (whereby future events approach and past events recede) is analogous to the physical experience of movement through space. Consistent with this hypothesis, experimentally reversing the metaphorical arrow of time (by having participants move backward through virtual space) completely eliminated the past-future asymmetry. We discuss how reducing psychological distance to the future may function to prepare people for upcoming action.

  12. Diagnostic Strategy in APR1400

    International Nuclear Information System (INIS)

    These features may bring out changes in operator tasks, changing the characteristics of tasks, or creating new tasks. Diagnostic strategy for identifying anomaly may be different especially in APR1400 from that in the analog control room due to the change of human-system interface, i.e. alarm system and display system. Since the first plant of APR1400 is being built at this moment, it is not known what strategies the operators will adopt in diagnosis tasks in the new operating environment. In this light, this paper aims at investigating operator's diagnostic strategies which are appropriate for APR1400. In order to collect data, several different approaches which are complementary are used to identify diagnostic strategies in the digital control room: analysis on audio/video recording of operation, observation in the simulator, and interview with the operators. The result shows that the digital control room introduces new strategies in the diagnosis, compared with the analog control room, and also changed the characteristics of strategies, mostly, by getting more support from the computerized system. This paper investigated how the digitalized control room may influence operator's diagnostic strategies. Several different approaches, i. e., audio/video record, observation of training, and the interview with operators, were used to gather information about the operator's behaviors. As a conclusion, this paper figured out that the digital control room introduces new strategies in the diagnosis, compared with the analog control room, and also changed the characteristics of the strategies, mostly, by getting more support from the computerized system. The operators interviewed also commented that the diagnosis in the APR1400 is quicker, more correct, and easier, compared with the analog control room

    2011-11-01

    This randomized controlled trial of 2168 DWI multiple offenders assigned to a state-wide ignition interlock program in Maryland compared non-compliance with interlock requirements among drivers who were closely monitored (by Westat staff) and drivers who received standard monitoring (by the Motor Vehicle Administration). Compliance comparisons relied on datalogger data from MVA's interlock providers plus driver records that contained demographic information, prior alcohol-related traffic violations, their dispositions, and interlock duration. Measures for quantifying non-compliance included rates per 1000 engine starts for initial breath test failures at varying BAC levels and time periods, retest failures, retest refusals, interlock disconnects, startup violations, and summation measures. Regression analysis estimated the effects of closer monitoring on non-compliance, using linear mixed models that included random driver effects and fixed effects for study-group assignment, prior alcohol-related traffic violations, and months of continuous datalogger data with a quadratic function that assessed changes and rates of change in interlock non-compliance over time. All the separate non-compliance rates and summary measures derived from them were lower for closer monitored than control drivers for continuous data series of at least 6, 12, or 24 months. The differences for initial test failures and the two summary measures were statistically significant. Most measures of non-compliance decreased significantly as continuous time on the interlock increased. Parallel trends in each study group indicated that drivers learned to improve their compliance over time. Thus, this study convincingly demonstrates that closer monitoring substantially enhanced compliance with requirements of the ignition interlock and that regardless of group assignment, compliance increased over time.

  2. Oil and gas exploration challenges: drilling deeper and closer to the community

    Energy Technology Data Exchange (ETDEWEB)

    Davison, Colin [Stealth Acoustical and Emission Control Inc (Canada)], email: cdavison@stealthacoustical.com

    2011-07-01

    There is a tendency for oil and gas companies to place their drilling sites closer to communities, small and large, and the noise impact of such drilling projects is becoming more of a challenge to their competitiveness. This paper discusses the challenges faced by these companies, and possible solutions for future development. Because drilling equipment is typically moved from one site to another, if it is robust enough and compact enough to be transported, the noise baseline for such moving installations is difficult to evaluate, and they may not be in compliance with different international regulations on noise assessment. Fully integrated solutions are needed in these industries and should be based in part on a better understanding of the drilling process itself but mainly on collaborative work with the acoustical engineering community to arrive at general guidelines on noise impact. Only then will the drilling companies, thanks to new drilling technology and acoustical mitigation, be able to drill deeper and closer to communities without noise disturbance.

  3. Tuberculosis diagnostics: Challenges and opportunities

    Full Text Available Tuberculosis (TB has been a disease affecting almost all parts of the world since ages. Lot many efforts came in the past for improving diagnosis and treatment. Also, an effective vaccine has been sought after for long. With the emergence of resistant strains of Mycobacterium tuberculosis, the causal organisms of tuberculosis, and complexities emerging due to other associated infections and disease conditions, there is a desperate need for further research input in the field. Be it the better medication and care or better resistance management, proper diagnostics holds the key to success. It has been observed that a high burden of the disease was accompanied by resource limitations and poor research set-up. The scenario remained like this for several decades. With the refreshed vision of resourceful countries and funding agencies, funding is being provided in many areas of research in tuberculosis diagnosis and treatment. This review has been written with an aim to bring forth the limitations of available methods in the field of diagnostics and making researchers aware about the changing scenario with better funding opportunities and support. The author visualizes an enthusiasm from all over the world for the development of better modalities and urges scientists to join the struggle at this very perfect time to take the challenge and come forward with innovations in this field.

  5. Diagnostic tools assessing airway remodelling in asthma.

    Science.gov (United States)

    Manso, L; Reche, M; Padial, M A; Valbuena, T; Pascual, C

    2012-01-01

    Asthma is an inflammatory disease of the lower airways characterised by the presence of airway inflammation, reversible airflow obstruction and airway hyperresponsiveness and alterations on the normal structure of the airways, known as remodelling. Remodelling is characterised by the presence of metaplasia of mucous glands, thickening of the lamina reticularis, increased angiogenesis, subepithelial fibrosis and smooth muscle hypertrophy/hyperplasia. Several techniques are being optimised at present to achieve a suitable diagnosis for remodelling. Diagnostic tools could be divided into two groups, namely invasive and non-invasive methods. Invasive techniques bring us information about bronchial structural alterations, obtaining this information directly from pathological tissue, and permit measure histological modification placed in bronchi layers as well as inflammatory and fibrotic cell infiltration. Non-invasive techniques were developed to reduce invasive methods disadvantages and measure airway remodelling-related markers such as cytokines, inflammatory mediators and others. An exhaustive review of diagnostic tools used to analyse airway remodelling in asthma, including the most useful and usually employed methods, as well as the principal advantages and disadvantages of each of them, bring us concrete and summarised information about all techniques used to evaluate alterations on the structure of the airways. A deep knowledge of these diagnostic tools will make an early diagnosis of airway remodelling possible and, probably, early diagnosis will play an important role in the near future of asthma.

  6. Disposable blast shields for use on NIF imaging diagnostics

    Science.gov (United States)

    Smith, Cal A.; Wang, Karen M.; Masters, Nathan

    2015-08-01

    The NIFs 192 lasers can deliver 2 MJ of energy to Target Chamber Center (TCC) to produce environments not available in any other experimental laboratory. The NIFs ability to deliver such intense energy to a small volume causes harsh consequences to experimental equipment and supporting diagnostics such as holhraums, support packages, target positioners, diagnostic equipment, and laser optics. Of these, the hohlraum and support packages are typically quickly vaporized and transformed into an expanding shell of high-hypersonic gases referred to as debris wind. During an experimental event such as fusion implosion, the target diagnostic components used to measure key observables in the experiment are subjected to extreme pressures and impact shocks due to incident debris wind loading. As diagnostics are positioned closer to TCC, the diagnostic pinhole stacks and other components along the diagnostic structure become more likely to be at or above the yield strength of the materials commonly used. In particular, the pinhole stack components and data recording instruments behind the pinholes are the most costly to replace. Thus, a conceptual configuration for a pinhole shield is proposed, analyzed, and tested with the intent of mitigating damage to the pinhole stack and imaging equipment and allowing immediate re-use of this diagnostic equipment. This pinhole shield would be a replaceable window that can be replaced quickly by inserting and removing it before and after each experimental laser shot, which will allow NIF to benefit from significant material and labor costs.

  7. Identifying features of 'pathological demand avoidance' using the Diagnostic Interview for Social and Communication Disorders (DISCO).

    O'Nions, Elizabeth; Gould, Judith; Christie, Phil; Gillberg, Christopher; Viding, Essi; Happé, Francesca

    2016-04-01

    The term 'pathological demand avoidance' (PDA) was coined by Elizabeth Newson to describe children within the autism spectrum who exhibit obsessive resistance to everyday demands and requests (Newson et al., Arch Dis Child 88:595-600, 2003). Clinical accounts describe avoidance strategies including apparently strategic use of distraction or socially shocking behaviour, and obsessive need for control, reflected in domineering behaviour to peers and adults. Educational and management approaches effective for PDA reportedly differ from those for 'typical' autism spectrum disorders (ASD), and include novelty, humour and flexibility. Identification of PDA in individuals with ASD may have important implications for management (Eaton and Banting, J Learn Disabil Offending Behav 3:150-157, 2012). Despite increasing interest, no clinician-rated instrument for PDA has been developed. Here, items relevant to PDA were identified from the Diagnostic Interview for Social and Communication Disorder (DISCO) (Wing et al., J Child Psychol Psychiatry 43:307-325, 2002). The most PDA-specific subset of relevant DISCO items was selected, based on low endorsement in general across a sample of 153 individuals assessed for possible ASD using the DISCO. Having selected 11 DISCO PDA items for the measure, a subset of individuals with a high number of these features was identified (N = 27). Consistent with Newson's descriptions, this high scoring group was characterised by lack of co-operation, use of apparently manipulative behaviour, socially shocking behaviour, difficulties with other people, anxiety and sudden behavioural changes from loving to aggression. All but one case met criteria for an ASD. This study brings the field a step closer to a clinician-rated measure of PDA features and highlights the need for further elucidation of the PDA phenotype.

    The US Congress passed the Renewable Fuels Standard (RFS) seven years ago. Since then, biofuels have gone from darling to scapegoat for many environmentalists, policy makers, and the general public. The reasons for this shift are complex and include concerns about environmental degradation, uncertainties about impact on food security, new access to fossil fuels, and overly optimistic timetables. As a result, many people have written off biofuels. However, numerous studies indicate that biofuels, if managed sustainably, can help solve pressing environmental, social and economic problems (Figure 1). The scientific and policy communities should take a closer look by reviewing the key assumptions underlying opposition to biofuels and carefully consider the probable alternatives. Liquid fuels based on fossil raw materials are likely to come at increasing environmental cost. Sustainable futures require energy conservation, increased efficiency, and alternatives to fossil fuels, including biofuels.

  9. Closer to Nature: the Ethics of ‘Green’ Representations in Animal Product Marketing

    animal production while the production at the same time presupposes a quite different paradigm of animal welfare. Two cases are used to illustrate this: 1) the Danish dairy company Arla Foods’ campaign with the tagline ‘Closer to Nature’, and 2) selected ‘quality brands’ that present themselves......Empirical cases from the Danish food market are examined in order to critically discuss the respective modes of communication in light of the premises of socially responsible consumer marketing. This analysis suggests that specific marketing instruments are used to sell animal products by blurring...... the difference between the paradigms of animal welfare used by producers, and the paradigms of animal welfare implicit in the public understanding of the concept. These instruments rely on the ethical, political and sustainable consumption discourses in order to sell one image of animal welfare in intensive...

  10. Role of Borna Disease Virus in neuropsychiatric illnesses : Are we inching closer ?

    2009-01-01

    Full Text Available The biological cause of psychiatric illnesses continues to be under intense scrutiny. Among the various neurotropic viruses, Borna disease virus (BDV is another virus that preferentially targets the neurons of the limbic system and has been shown to be associated with behavioural abnormalities. Presence of various BDV markers, including viral RNA, in patients with affective and mood disorders have triggered ongoing debate worldwide regarding its aetiopathogenic relationship. This article analyses its current state of knowledge and recent advances in diagnosis in order to prove or refute the association of BDV in causation of human neuropsychiatric disorders. This emerging viral causative association of behavioural disorders, which seems to be inching closer, has implication not only for a paradigm shift in the treatment and management of neuropsychiatric illnesses but also has an important impact on the public health systems.

    International Nuclear Information System (INIS)

    This paper is subdivided into three chapters to match three corresponding lectures. The goals of the first chapter are to define the neutral-beam-heated, quasi-d.c. mirror confinement systems under discussion here and to give a general example of mirror diagnostics by listing and very briefly discussing the diagnostics used on the 2XIIB experiment at the Lawrence Livermore Laboratory. The second chapter develops mirror machine diagnostics in more detail, and adds background for a few selected diagnostics of particular importance to mirror machine studies. The third chapter discusses the special diagnostic needs of future mirror machines, with emphasis on diagnostics involving the higher-power neutral beams used with them

    Xiao, Y Jenny; Van Bavel, Jay J

    2012-07-01

    Three studies demonstrated that collective identity and identity threat shape representations of the physical world. In Study 1, New York Yankees fans estimated Fenway Park, the stadium of a threatening out-group (but not Camden Yards, the stadium of a neutral out-group) to be closer than did non-Yankees fans. In Study 2, the authors manipulated identity threat among people affiliated (or not) with New York University (NYU). When Columbia University was portrayed as threatening to NYU, NYU affiliates estimated Columbia as closer than did non-affiliates, compared with when Columbia was nonthreatening. In Study 3, Americans who perceived more symbolic threats from Mexican immigration estimated Mexico City as closer. Collective identification with the in-group moderated effects of threat on distance estimations. These studies suggest that social categorization, collective identification, and identity threat work in concert to shape the representations of the physical world.

    2011-11-01

    Current health policy in England regarding the management of childhood illness advocates for care to be delivered as close to home as possible. The aim of this article is to report findings from a qualitative component of a larger study evaluating models of care closer to home (CCTH) for children and young people who are ill. The focus is on parents' psychosocial experience of receiving CCTH for their ill child. A qualitative case study design was used, with four Primary Care Trusts in England as the case study sites. In-depth, semi-structured interviews were conducted with 27 parents and one extended family caregiver of children using CCTH services within the case study sites. Interviews were conducted face-to-face and audio-recorded with permission. Data were collected in 2009. There was an overall preference for CCTH over hospital-based care where possible. The parents in this study experienced differing levels of responsibility as part of this care, and responded to this in different ways. Being supported emotionally and socially by practitioners was an important part of receiving CCTH for parents, especially when they had increased responsibility as part of this care. Developing relationships with practitioners appeared to be a medium through which parents received support. If the provision of CCTH continues to expand in line with current policy, provision of support for parents should be considered a fundamental aspect of service development. PMID:21623985

  6. Does Weak Turbulence Impact PMSEs' Strengths Closer To The Northern Pole?

    2015-12-01

    Existing 51.0 MHz VHF radar at Eureka (80N, 86W) in northern Canada is located closer to both the northern magnetic and geomagnetic poles. A recent calibrated study of Polar Mesosphere Summer Echoes (PMSE) using this radar supports the previous results by other radars that the absolute signal strength of PMSE in this region is relatively weak compared with the radar observations located at high latitudes. Although very cold temperature and existence of charged ice particles are the most important ingredient required for PMSE to appear, several other factors could potentially influence the absolute signal strengths of these echoes. One of them is neutral air turbulence. Previous studies indicate that upper mesospheric turbulence's strength decreases with latitudes, especially in the very high latitudes [Becker, 2004; Lubken et. al., 2009]. In this study, we investigate long-term mesospheric turbulence strengths at Eureka and study how they could be associated with the weak PMSE signal strengths compared with other high latitude conditions, where PMSE are strong.

  7. A closer look at the discrimination outcomes in the IAT literature.

    2016-08-01

    To what extent the IAT (Implicit Association Test, Greenwald et al., 1998) predicts racial and ethnic discrimination is a heavily debated issue. The latest meta-analysis by Oswald et al. (2013) suggests a very weak association. In the present meta-analysis, we switched the focus from the predictor to the criterion, by taking a closer look at the discrimination outcomes. We discovered that many of these outcomes were not actually operationalizations of discrimination, but rather of other related, but distinct, concepts, such as brain activity and voting preferences. When we meta-analyzed the main effects of discrimination among the remaining discrimination outcomes, the overall effect was close to zero and highly inconsistent across studies. Taken together, it is doubtful whether the amalgamation of these outcomes is relevant criteria for assessing the IAT's predictive validity of discrimination. Accordingly, there is also little evidence that the IAT can meaningfully predict discrimination, and we thus strongly caution against any practical applications of the IAT that rest on this assumption. However, provided that the application is thoroughly informed by the current state of the literature, we believe the IAT can still be a useful tool for researchers, educators, managers, and students who are interested in attitudes, prejudices, stereotypes, and discrimination.

  8. A Proposal for Measuring Interactivity that Brings Learning Effectiveness

    Directory of Open Access Journals (Sweden)

    Tosh Yamamoto

    2010-03-01

    Full Text Available It is proposed in this paper that some type of way to measure and visualize interactivity in the multimedia or e-Learning contents is necessary in order to clearly identify interactivity that brings learning effectiveness. Interactivity during learning will arouse students’ intellectual curiosity and motivate them to learn further. Although the interaction in the communication between the teacher and his/her students in a regular classroom is ideal, it is not possible to maintain the equivalence in the multimedia or e-Learning contents. In order to rigorously formalize the field of measuring interactivity as a theory, theoretical constructs such as interactivity, interest, knowledge, and experience are redefined first. Then, the defined “interactivity” is broken down to subcomponents to develop an assessment tool for the interactivity which brings learning effectiveness. In the end, it is proved that the interactivity in learning can be measured.

  9. SEPARATION OF MARKETS AND FINANCIAL INSTABILITY: A CLOSER LOOK TO CLASSICAL DICHOTOMY

    Directory of Open Access Journals (Sweden)

    Mehdi HADIAN

    2016-08-01

    Full Text Available Several financial crises occurred over the past three decades have provoked debates in the literature of liberalization and deregulation of financial markets. By surveying the theory of classical dichotomy and its critiques, the notion of “separation” between the financial and real sectors has been introduced in this paper. It argues that the existence and expansion of this separation will lead to financial crisis. In order to identify the separation “price-to-earnings ratio” index has been proposed. By applying the data of Tehran’s Stock Exchange during 2002:2-2015:1, several episodes of this separation are recognizable. Considering the factors causing the expansion of the separation, it is essential to reestablish regulations and mechanisms of financial markets in a way that reduces the separation and hence lessen financial crises. In this view, Islamic financial rules can provide an economic system with mechanisms bringing harmony between the real and the financial sectors.

    2016-03-01

    Full Text Available The amount of open access content stored in repositories has increased dramatically, which has created new technical and organisational challenges for bringing this content together. The COnnecting REpositories (CORE project has been dealing with these challenges by aggregating and enriching content from hundreds of open access repositories, increasing the discoverability and reusability of millions of open access manuscripts. As repository managers and library directors often wish to know the details of the content harvested from their repositories and keep a certain level of control over it, CORE is now facing the challenge of how to enable content providers to manage their content in the aggregation and control the harvesting process. In order to improve the quality and transparency of the aggregation process and create a two-way collaboration between the CORE project and the content providers, we propose the CORE Dashboard.

  13. Bringing History Home. Postcolonial Immigrants and the Dutch Cultural Arena

    Directory of Open Access Journals (Sweden)

    S. Legêne

    2011-01-01

    Full Text Available Bringing History Home: Postcolonial Immigrants and the Dutch Cultural ArenaThree Dutch-language monographs published in 2008-2009 by Ulbe Bosma, Lizzy van Leeuwen and Gert Oostindie in the context of the interdisciplinary research programme Bringing History Home, present a history of identity politics in relation to ‘postcolonial immigrants’. This term refers to some 500,000 people who since 1945 arrived in the Netherlands from Indonesia and the former Dutch New Guinea, Suriname or the Antillean islands in the Caribbean. Bosma traces the development of postcolonial immigrant organizations. In interaction with government policies, these organizations moved from mere socioeconomic emancipation struggles to mere cultural identity politics. Van Leeuwen takes such cultural identity politics as the starting point for her analysis of Indo-Dutch and Dutch Indies cultural initiatives and the competing interests at stake in the Indies heritage discourse. Oostindie discusses these developments in terms of community development and change within Dutch society at large. He introduces the notion of a ‘postcolonial bonus’. In postcolonial Netherlands, this bonus was available to immigrants on the grounds of a shared colonial past. Today, this bonus is (almost spent. The review discusses the three monographs, as well as the coherence of Bringing History Home as a research programme. Legêne argues, that notwithstanding valuable research outcomes, the very category of postcolonial immigrants does not constitute a convincing category of analysis.

  14. A Closer Look at the Thresholds of Thermal Damage: Workshop Report by an ICNIRP Task Group

    Sienkiewicz, Zenon; van Rongen, Eric; Croft, Rodney; Ziegelberger, Gunde; Veyret, Bernard

    2016-01-01

    Abstract The International Commission on Non-Ionizing Radiation Protection issued guidelines in 1998 for limiting public and occupational exposure to radiofrequency electromagnetic fields (100 kHz to 300 GHz). As part of the process of updating this advice, a 2‐d workshop titled “A closer look at the thresholds of thermal damage” was held from 26–28 May 2015 in Istanbul to re-examine the thermal basis of the guidelines and to provide further information on heat-related effects and thresholds of thermal damage. Overall, the workshop provided much useful information relevant to revision of the guidelines. Participants indicated that the effects of heating from radiofrequency fields are consistent with those from other sources, and that the information derived from those studies can be applied to radiofrequency-induced heating. Another conclusion was that absolute temperature of tissues was more important for thermal damage than temperature change. The discussion suggested that the 6‐min averaging time used in international guidelines was valid for whole-body exposures but with a large uncertainty: 30 min may be a more appropriate averaging time for localized exposures, and less than 1 min for implanted medical devices. The duration of whole-body radiofrequency exposure is a critical parameter that often determines the effect threshold, but this will be affected by other, ongoing thermoregulation, which is dependant on many factors. The thresholds for localized radiofrequency exposure were difficult to determine because of the potential range of exposure conditions and the possibility of radiofrequency-induced local hotspots. Suggestions for future dose metrics and further research were discussed and are included in this report. PMID:27472755

  15. Jets Spout Far Closer to Black Hole Than Thought, Scientists Say

    Science.gov (United States)

    2004-01-01

    Scientists at the Massachusetts Institute of Technology, taking advantage of multiple unique views of black hole particle jets over the course of a year with NASA's Chandra X-ray Observatory, have assembled a "picture" of the region that has revealed several key discoveries. They have found that the jets may be originating five times closer to the black hole than previously thought; they see in better detail how these jets change with time and distance from the black hole; and they could use this information as a new technique to measure black hole mass. Presented today in a press conference at the meeting of the American Astronomical Society in Atlanta, the observation will ultimately help solve the mystery of the great cosmic contradiction, in which black holes, notorious for pulling matter in, somehow manage to also shoot matter away in particle jets moving close to the speed of light. The observation is of a familiar source named SS 433 -- a binary star system within our Galaxy in the constellation Aquila, the Eagle, about 16,000 light years away. The black hole and its companion are about two-thirds closer to each other than the planet Mercury is to the Sun. The jets shoot off at 175 million miles per hour, 26 percent of light speed. "The high-speed jets in nearby SS 433 may be caused by the same mechanisms as the powerful outflows in the most distant and much more massive black holes, such as quasars," said Laura Lopez, an undergraduate student at MIT and lead author on a paper about the result. "SS 433 provides a nice local laboratory to study the formation of and conditions in relativistic jets." Dr. Herman Marshall, Ms. Lopez's research supervisor, led the investigation. Matter from the companion star pours into the black hole via a swirling accretion disk, much like water down a drain. Black hole particles jets are thought to be produced as some of the matter encounters strong magnetic fields close to the black hole. SS 433 is angled in such a way that

  17. Cable Diagnostic Focused Initiative

    Energy Technology Data Exchange (ETDEWEB)

    Hartlein, R.A.; Hampton, R.N.

    2010-12-30

    This report summarizes an extensive effort made to understand how to effectively use the various diagnostic technologies to establish the condition of medium voltage underground cable circuits. These circuits make up an extensive portion of the electric delivery infrastructure in the United States. Much of this infrastructure is old and experiencing unacceptable failure rates. By deploying efficient diagnostic testing programs, electric utilities can replace or repair circuits that are about to fail, providing an optimal approach to improving electric system reliability. This is an intrinsically complex topic. Underground cable systems are not homogeneous. Cable circuits often contain multiple branches with different cable designs and a range of insulation materials. In addition, each insulation material ages differently as a function of time, temperature and operating environment. To complicate matters further, there are a wide variety of diagnostic technologies available for assessing the condition of cable circuits with a diversity of claims about the effectiveness of each approach. As a result, the benefits of deploying cable diagnostic testing programs have been difficult to establish, leading many utilities to avoid the their use altogether. This project was designed to help address these issues. The information provided is the result of a collaborative effort between Georgia Tech NEETRAC staff, Georgia Tech academic faculty, electric utility industry participants, as well as cable system diagnostic testing service providers and test equipment providers. Report topics include: •How cable systems age and fail, •The various technologies available for detecting potential failure sites, •The advantages and disadvantages of different diagnostic technologies, •Different approaches for utilities to employ cable system diagnostics. The primary deliverables of this project are this report, a Cable Diagnostic Handbook (a subset of this report) and an online

  18. Are we closer to seeing carcinoma in situ in the upper urinary tract?

    Aboumarzouk, Omar

    2016-01-01

    Introduction There is observed increase in detection rate of upper urinary tract urothelial cancer worldwide. This is a result of improved imaging as well as implementation of novel technologies of direct visualization of upper urinary tract. Standard techniques still remain insufficient to diagnose flat urothelial lesions. Carcinoma in situ is characterized by flat disordered proliferation of urothelial cells with marked cytologic abnormality, which occur within one cell layer as well as full thickness urothelium and therefore requires a better technology to pick up early and subtle mucosal changes. Material and methods The review presents available diagnostic tools in detection of upper urinary tract urothelial cancer and their ability to depict carcinoma in situ. Results Ureterorenoscopy is an investigation of choice as various promising techniques are under pilot investigations to enhance visualization of upper urinary tract carcinoma in situ. So far only photodynamic diagnosis has been reported to be as effective in detection of carcinoma in situ in the upper as within the lower urinary tract. Conclusions Although we are close to see upper urinary tract carcinoma in situ all new promising diagnostic techniques still require further validation in multicenter clinical trials to indicate any change to current recommendations.

    Clinical diagnostics in metabolic bone diseases cover a broad spectrum of conventional and state of the art methods ranging from the medical history and clinical examination to molecular imaging. Patient treatment is carried out in an interdisciplinary team due to the multiple interactions of bone with other organ systems. Diagnosis of osteoporosis is supported by high level national guidelines. A paradigm shift concerning the clinical relevance of bone mineral density measurement renders this now to be a strong risk factor rather than a diagnostic parameter, while strengthening the value of other clinical factors for risk assessment. The impact of parameters for muscle mass, structure and function is steadily increasing in all age groups. In order to identify underlying diseases that influence bone metabolism a panel of general laboratory diagnostic parameters is recommended. Markers for bone formation and resorption and specific parameters for the regulation of calcium and phosphate metabolism should be evaluated by specialists because they require diligence in preanalytics and experience in interpretation. Genetic diagnosis is well established for rare bone diseases while diagnostic panels are not yet available for routine diagnostics in polygenetic diseases such as osteoporosis. Conventional radiology is still very important to identify, e. g. fractures, osteolytic and osteoblastic lesions and extraosseous calcifications; however tomography-based methods which combine, e. g. scintigraphy or positron emission technologies with anatomical imaging are of increasing significance. Clinical diagnostics in osteology require profound knowledge and are subject to a dynamic evolution. PMID:27307159

    Full Text Available “See, the Conqu’ring Hero Comes” goes the famous chorus from Handel’s Judas Maccabeus, but how does the hero conquer? Achilles defeats his enemies through his extraordinary prowess in battle, Odysseus by using his wit, but some heroes must abandon the trappings of civilization in order to conquer. This paper examines two examples of such heroes from Germanic and Greco-Roman myth: Beowulf and Herakles. In the texts analyzed, these heroes not only set aside their civilized veneer, but must journey into the territory of the monster they wish to destroy and there use savagery to defeat the savage, in order to bring civilization.

    2008-01-01

    This report states that bringing about the rapid adjustment of house prices to trend levels is the best means of returning stability to the housing market. The paper also calls for the restriction of GSE capital in bubble-inflated markets, with the intent of forcing house prices in these areas to return to trend level. The removal of capital from bubble markets and the consequent infusion of loans into non-bubble markets would stabilize prices in these areas, thus preventing a downward price ...

  12. Tapping the grapevine: a closer look at word-of-mouth as a recruitment source.

    Science.gov (United States)

    Van Hoye, Greet; Lievens, Filip

    2009-03-01

    To advance knowledge of word-of-mouth as a company-independent recruitment source, this study draws on conceptualizations of word-of-mouth in the marketing literature. The sample consisted of 612 potential applicants targeted by the Belgian Defense. Consistent with the recipient-source framework, time spent receiving positive word-of-mouth was determined by the traits of the recipient (extraversion and conscientiousness), the characteristics of the source (perceived expertise), and their mutual relationship (tie strength). Only conscientiousness and source expertise were determinants of receiving negative word-of-mouth. In line with the accessibility-diagnosticity model, receiving positive employment information through word-of-mouth early in the recruitment process was positively associated with perceptual (organizational attractiveness) and behavioral outcomes (actual application decisions), beyond potential applicants' exposure to other recruitment sources.

  13. A Review of Bring Your Own Device on Security Issues

    Full Text Available Mobile computing has supplanted internet computing because of the proliferation of cloud-based applications and mobile devices (such as smartphones, palmtops, and tablets. As a result of this, workers bring their mobile devices to the workplace and use them for enterprise work. The policy of allowing the employees to work with their own personal mobile devices is called Bring Your Own Devices (BYOD. In this article, we discuss BYOD’s background, prevalence, benefits, challenges, and possible security attacks. We then review contributions of academic researchers on BYOD. The Universiti Putra Malaysia online databases (such as IEEE Xplore digital library, Elsevier, Springer, ACM digital library were used to search for peer-reviewed academic publications and other relevant publications on BYOD. The Google Scholar search engine was also used. Our thorough review shows that security issues comprise the most significant challenge confronting BYOD policy and that very little has been done to tackle this security challenge. It is our hope that this review will provide a theoretical background for future research and enable researchers to identify researchable areas of BYOD.

    We want to present ideas on ways of bringing technology to college and high school physics classrooms. We focus in particular on our outreach initiative in supporting a number of school districts with ways to improve high school physics education. This initiative is part of Project IMPACTSEED (IMproving Physics And Chemistry Teaching in SEcondary Education), a No-Child Left Behind grant funded by the Alabama Commission on Higher Education. This project is motivated by a major local need: A large number of high school physics teachers teach out of field. IMPACTSEED aims at helping high school teachers learn and master the various physics topics required by the Alabama course of study. Teachers are offered year-round support through a rich variety of programs: a two-week long summer institute, a series of five technology workshops, and onsite year-round support. Through our hands-on approach, we have identified a number of ways of bringing technology into physics classrooms. A number of technology projects were assigned to the teachers so as to show their students how physics connects to the technological devices around us. IMPACTSEED aims at providing our students with a physics education that enjoys continuity and consistency from high school to college.

    The world's largest ground-based solar telescope is one step closer to operation with the acceptance of the deformable mirror engineered by AOA Xinetics, a Northrop Grumman Corporation company. The Daniel K. Inouye Solar Telescope (DKIST), currently under construction in Haleakala, Hawaii, will offer unprecedented high-resolution images of the sun using the latest adaptive optics technology to provide its distortion-free imaging.Led by the National Solar Observatory (NSO) and the Association of Universities for Research in Astronomy (AURA), the Inouye Solar Telescope will help scientists better understand how magnetic fields affect the physical properties of the Sun, what roles they play in our solar system and how they affect Earth.Ground-based telescopes, whether observing the sun or the night sky must contend with atmospheric turbulence that acts as a flexible lens, constantly reshaping observed images. This turbulence makes research on solar activity difficult and drives the need for the latest adaptive optics technology.To provide DKIST with the distortion-free imaging it requires, AOA Xinetics designed a deformable mirror with 1,600 actuators, four times the normal actuator density. This deformable mirror (DM) is instrumental in removing all of the atmospheric blurriness that would otherwise limit the telescope's performance. The mirror also has an internal thermal management system to handle the intense solar energy coming from DKIST's telescope. This poster provides the history behind this incredible success story.

    Only textbook to focus primarily on the topic of pitfalls in diagnostic radiology. Highlights the pitfalls in a comprehensive and systematic manner. Written by experts in different imaging modalities and subspecialties from reputable centers across the world. The practice of diagnostic radiology has become increasingly complex, with the use of numerous imaging modalities and division into many subspecialty areas. It is becoming ever more difficult for subspecialist radiologists, general radiologists, and residents to keep up with the advances that are occurring year on year, and this is particularly true for less familiar topics. Failure to appreciate imaging pitfalls often leads to diagnostic error and misinterpretation, and potential medicolegal problems. Diagnostic errors may be due to various factors such as inadequate imaging technique, imaging artifacts, failure to recognize normal structures or variants, lack of correlation with clinical and other imaging findings, and poor training or inexperience. Many, if not most, of these factors are potentially recognizable, preventable, or correctable. This textbook, written by experts from reputable centers across the world, systematically and comprehensively highlights the pitfalls that may occur in diagnostic radiology. Both pitfalls specific to different modalities and techniques and those specific to particular organ systems are described with the help of numerous high-quality illustrations. Recognition of these pitfalls is crucial in helping the practicing radiologist to achieve a more accurate diagnosis.

    The Madden-Julian Oscillation (MJO) interacts with, and influences, a wide range of weather and climate phenomena (e.g., monsoons, ENSO, tropical storms, mid-latitude weather), and represents an important, and as yet unexploited, source of predictability at the subseasonal time scale. Despite the important role of the MJO in our climate and weather systems, current global circulation models (GCMs) exhibit considerable shortcomings in representing this phenomenon. These shortcomings have been documented in a number of multi-model comparison studies over the last decade. However, diagnosis of model performance has been challenging, and model progress has been difficult to track, due to the lack of a coherent and standardized set of MJO diagnostics. One of the chief objectives of the US CLIVAR MJO Working Group is the development of observation-based diagnostics for objectively evaluating global model simulations of the MJO in a consistent framework. Motivation for this activity is reviewed, and the intent and justification for a set of diagnostics is provided, along with specification for their calculation, and illustrations of their application. The diagnostics range from relatively simple analyses of variance and correlation, to more sophisticated space-time spectral and empirical orthogonal function analyses. These diagnostic techniques are used to detect MJO signals, to construct composite life-cycles, to identify associations of MJO activity with the mean state, and to describe interannual variability of the MJO.

    2004-08-30

    The National Ignition Facility (NIF) requires diagnostics to analyze high-energy density physics experiments. A VISAR (Velocity Interferometry System for Any Reflector) diagnostic has been designed to measure shock velocities, shock breakout times, and shock emission of targets with sizes from 1 to 5 mm. An 8-inch-diameter fused silica triplet lens collects light at f/3 inside the 30-foot-diameter vacuum chamber. The optical relay sends the image out an equatorial port, through a 2-inch-thick vacuum window, and into two interferometers. A 60-kW VISAR probe laser operates at 659.5 nm with variable pulse width. Special coatings on the mirrors and cutoff filters are used to reject the NIF drive laser wavelengths and to pass a band of wavelengths for VISAR, passive shock breakout light, or thermal imaging light (bypassing the interferometers). The first triplet can be no closer than 500 mm from the target chamber center and is protected from debris by a blast window that is replaced after every event. The front end of the optical relay can be temporarily removed from the equatorial port, allowing other experimenters to use that port. A unique resolution pattern has been designed to validate the VISAR diagnostic before each use. All optical lenses are on kinematic mounts so that the pointing accuracy of the optical axis can be checked. Seven CCD cameras monitor the diagnostic alignment.

  20. A closer look at a coronal loop rooted in a sunspot umbra

    2015-01-01

    Extreme UV (EUV) and X-ray loops in the solar corona connect regions of enhanced magnetic activity, but usually they are not rooted in the dark umbrae of sunspots. This is because there the strong magnetic field suppresses convection and thus the Poynting flux of magnetic energy into the upper atmosphere is not significant within the umbra, as long as there are no light bridges, umbral dots. Here we report a rare observation of a coronal loop rooted in the dark umbra of a sunspot without any traces of light bridges or umbral dots. We used the slit-jaw images and spectroscopic data from the IRIS and concentrate on the line profiles of O IV and Si IV that show persistent strong redshifted components in the loop rooted in the umbra. Using the ratios of O IV, we can estimate the density and thus investigate the mass flux. The coronal context and temperature diagnostics of these observations is provided through the EUV channels of the AIA. The coronal loop, embedded within cooler downflows, is hosting supersonic d...

    Beamlet is instrumented extensively to monitor the performance of the overall laser system and many of its subsystems. Beam diagnostics, installed in key locations, are used to fully characterize the beam during its propagation through the multipass cavity and the laser`s output section. This article describes the diagnostics stations located on Beamlet and discusses the design, calibration, and performance of the Beamlet calorimeters. The authors used Nova`s diagnostics packages to develop the Beamlet design to determine beam energy, spatial profile, temporal profile, and other beam parameters. Technologic improvements within the last several years in controls, charge-coupled device (CCD) cameras, and fast oscilloscopes have allowed the authors to obtain more accurate measurements on the Beamlet laser system. They briefly cover some of these techniques, including a description of their LabVIEW based data acquisition system.

    2015-11-24

    There is a growing need to enhance our capabilities in medical and environmental diagnostics. Synthetic biologists have begun to focus their biomolecular engineering approaches toward this goal, offering promising results that could lead to the development of new classes of inexpensive, rapidly deployable diagnostics. Many conventional diagnostics rely on antibody-based platforms that, although exquisitely sensitive, are slow and costly to generate and cannot readily confront rapidly emerging pathogens or be applied to orphan diseases. Synthetic biology, with its rational and short design-to-production cycles, has the potential to overcome many of these limitations. Synthetic biology devices, such as engineered gene circuits, bring new capabilities to molecular diagnostics, expanding the molecular detection palette, creating dynamic sensors, and untethering reactions from laboratory equipment. The field is also beginning to move toward in vivo diagnostics, which could provide near real-time surveillance of multiple pathological conditions. Here, we describe current efforts in synthetic biology, focusing on the translation of promising technologies into pragmatic diagnostic tools and platforms.

    Some 150 million years ago, a strange creature died in a tropical lagoon that today is located in Bavaria, Germany. In 1861, a single feather of this creature was discovered. Not long afterward, a complete fossil was found with the same bird-like feathers but dinosaur-like anatomical features. Darwin had just published 'On the Origin of Species'; could this be the missing link that Darwin's supporters hoped to find? Recently, two of the now eleven discovered Archaeopteryx fossils, and that first feather, were brought to SLAC, where, using the intense X-ray beam, researchers searched for the chemical remains of the original living creatures. Please join us for this lecture, which will explain how the studies attempt to bring the original dino-bird back to life.

    We report our experience in bringing science into US and French classrooms. We participated in the US scientific educational program Project ASTRO. It is based on a partnership between a school teacher and an astronomer. They together design and realize simple and interesting scientific activities for the children to learn and enjoy science. We present four hands-on activities we realized in a 4th-grade class (10 yr-old kids) in Tucson (USA) in 2002-2003. Among the covered topics were: the Solar System, the Sun (helioseismology) and the Galaxies. We also present a similar experience done in two classrooms in 2005, in Chatenay-Malabry (France) in partnership with an amateur astronomy association (Aphelie). This is a pleasant and rewarding activity, extremely well appreciated by the children and the school teachers. It furthermore promotes already at a young age the excitement of science, and provides concrete examples of the scientific methodology.

  8. Bringing the power of dynamic languages to hardware control systems

    CERN Document Server

    Caicedo, J M; Neufeld, N

    2009-01-01

    Hardware control systems are normally programmed using high-performance languages like C or C++ and increasingly also Java. All these languages are strongly typed and compiled which brings usually good performance but at the cost of a longer development and testing cycle and the need for more programming expertise. Dynamic languages which were long thought to be too slow and not powerful enough for control purposes are, thanks to modern powerful computers and advanced implementation techniques, fast enough for many of these tasks. We present examples from the LHCb Experiment Control System (ECS), which is based on a commercial SCADA software. We have successfully used Python to integrate hardware devices into the ECS. We present the necessary lightweight middle-ware we have developed, including examples for controlling hardware and software devices. We also discuss the development cycle, tools used and compare the effort to traditional solutions.

  9. Bringing history to life: simulating landmark experiments in psychology.

    2006-05-01

    The course in history of psychology can be challenging for students, many of whom enter it with little background in history and faced with unfamiliar names and concepts. The sheer volume of material can encourage passive memorization unless efforts are made to increase student involvement. As part of a trend toward experiential history, historians of science have begun to supplement their lectures with demonstrations of classic physics experiments as a way to bring the history of science to life. Here, the authors report on computer simulations of five landmark experiments from early experimental psychology in the areas of reaction time, span of attention, and apparent motion. The simulations are designed not only to permit hands-on replication of historically important results but also to reproduce the experimental procedures closely enough that students can gain a feel for the nature of early research and the psychological processes being studied.

  11. Requirements for ITER diagnostics

    International Nuclear Information System (INIS)

    The development and design of plasma diagnostics for the International Thermonuclear Experimental Reactor (ITER) present a formidable challenge for experimental plasma physicists. The large plasma size, the high central density and temperature and the very high thermal wall loadings provide new challenges for present measurement techniques and lead to a search for new methods. But the physics and control requirements for the long burn phase of the discharge, combined with very limited access to the plasma, constrained by the requirement for radiation shielding of the coils and sharing of access ports with heating and current drive power, remote manipulation, fueling and turn blanket modules, make for very difficult design choices. An initial attempt at these choices has been made by an international team of diagnostic physicists, gathering together in a series of three workshops during the ITER Conceptual Design Activity. This paper is based on that report and provides a summary of its most important points. To provide a background against which to place the diagnostic requirements and design concepts, the ITER device, its most important plasma properties and the proposed experimental program will be described. The specifications for the measurement of the plasma parameters and the proposed diagnostics for these measurements will then be addressed, followed by some examples of the design concepts that have been proposed. As a result of these design studies, it was clear that there were many uncertainties associated with these concepts, particularly because of the nuclear radiation environment, so that a Research and Development Program for diagnostic hardware was established. It will also be briefly summarized

    International Nuclear Information System (INIS)

    This is the third edition of CSA Standard C22.2 No. 114 (now CAN/CSA-C22.2 No. 114), which is one of a series of standards issued by the Canadian Standards Association under Part II of the Canadian Electrical Code. This edition marks an important shift towards harmonization of Canadian requirements with those of the European community and the United States. Also important to this edition is the expansion of its scope to include the complete range of diagnostic imaging and radiation therapy equipment, rather than solely radiation-emitting equipment. In so doing, equipment previously addressed by CSA Standard C22.2 No. 125, Electromedical Equipment, specifically lasers for medical applications and diagnostic ultrasound units, is now dealt with in the new edition. By virtue of this expanded scope, many of the technical requirements in the electromedical equipment standard have been introduced to the new edition, thereby bringing CSA Standard C22.2 No. 114 up to date. 14 tabs., 16 figs

  14. Demarketing fear: Bring the nuclear issue back to rational discourse

    International Nuclear Information System (INIS)

    This paper attempts to explore the strategies for breaking the deadlock between the demand for resolving climate crisis and the resistance to deploying nuclear power. Since our present renewable technology is not advanced enough to replace fossil fuel power plants, nuclear power becomes the only available means that can buy us more time to explore better energy sources for coping with the dilemma of global warming and energy security. Therefore, this paper proposes an elaborated fear appeal framework that may shed light on the intervention points for mitigating fear. By examining the influence of fear appeal on the nuclear issue, three strategies for demarketing the nuclear fear of the public are recommended. The paper concludes that only when energy policy makers and the nuclear industry recognize the significance of minimizing fear and begin to work on removing the sources of fear, can we then expect to bring the nuclear issue back to rational discourse. - Highlights: • Both cognition and emotion are critical in decision-making processes. • Dealing with the emotion of fear is essential for resolving the nuclear issue. • Fear should be mitigated to make rational discourses on nuclear power happen. • Fear can be mitigated by manipulating issue familiarity and response feasibility. • Using equivalency and issue framing may alter public perceptions of nuclear power

  15. Geodesy Brings the Geoscience Community Together as Geophysicists

    Geodesy, the science of determining Earth's shape, gravity field and rotation, has been in existence for millennia. Today, few geoscientists identify with the pure science of geodesy, though many use geodetic tools and data for their research. In 2014, we interviewed members of the UNAVCO community and asked, "Do you call yourself a geodesist?" Most replied that they used geodesy, but would call themselves "geophysicists". This "use of geodesy" for other fields of study, particularly for geophysics-related fields, is consistent with an analysis of AGU's sections and focus groups. Additional analysis of geoscience departments at U.S. universities would suggest a similar trend. The expanding use of geodetic tools and geodetic data for many fields of research such as geophysics, tectonophysics, geodynamics, space physics, geology, geomorphology, seismology, hydrology, volcanology, glaciology, paleontology, paleoseismology, structural geology, meteorology, ecology, archaeology, oceanography, geography, soil science, atmospheric science, and snow science, may provide an approach to bringing diverse fields together under the moniker of geoscience and geoscientists. Scientists using a shared approach to research and education might be able to see themselves under the broader identity of geoscientist. The hurdle to making this transformation towards a larger shared voice in public discourse, is the more common use of "geophysicist" among the geodesy community, which is tied to the strong foundation of physics and mathematics needed to work with geodetic data and tools.

  16. Bringing Western-standard service stations to the Baltic countries

    International Nuclear Information System (INIS)

    Neste is the only Western oil company so far to have established a service station presence in the Baltic, with the exception of Norway's Statoil, which has one outlet near Tallinn Airport. Neste has an important logistical advantage compared to other companies in this respect as its two Finnish refineries are ideally located for supplying the region with high-quality petroleum products. Neste's first joint venture in the Baltic, Traffic Service, based in Estonia, was set up with Eesti Kutus in 1988 and opened its first service station in 1990. Other joint ventures are now up and running in Latvia, Lithuania, Poland, and St. Petersburg. A total of 10 - 15 stations, the majority strategically located along the route of the Via Baltica, are expected to be operational by the end of this year. The Neste network comprises a combination of new outlets and refurbished older stations that have been modernized to bring them up to Western standards. These offer a comprehensive range of fuels, lubricants, spare parts, and accessories, as well as food, confectionery, and coffee shop services. Some stations also offer repair and car wash facilities. Adapting to the transition from a communist economy to a Western, capitalist one has not been easy for the Baltic countries, and has inevitably created difficulties for companies like Neste, in areas such as legislation covering land ownership. Neste's joint ventures have also encountered difficulties in instilling the Western approach to business efficiency, and customer service in a workforce used to the Soviet retail system

    Creative partnerships between scientists and journalists open new opportunities to bring the excitement of scientific discoveries to wider audiences. Research tells us that the majority of the general public now gets more science and technology news from the Internet than from TV sources (2014 NSF Science and Engineering Indicators). In order to reach these audiences news organizations must embrace multiple forms of multimedia. We will review recent research on how the new multimedia landscape is changing the way that science news is consumed and how news organizations are changing the way they deliver news. News programs like Inside Science, and other examples of new partnerships that deliver research news to journalists, teachers, students, and the general public will be examined. We will describe examples of successful collaborations including an article by a former Newsweek science reporter entitled "My 1975 'Cooling World' Story Doesn't Make Today's Climate Scientists Wrong," which got reprinted in Slate, RealClearScience, and mentioned in Factcheck.org and USA Today.

  18. Disulfide Bridges: Bringing Together Frustrated Structure in a Bioactive Peptide.

    Disulfide bridges are commonly found covalent bonds that are usually believed to maintain structural stability of proteins. Here, we investigate the influence of disulfide bridges on protein dynamics through molecular dynamics simulations on the cysteine-rich trypsin inhibitor MCoTI-II with three disulfide bridges. Correlation analysis of the reduced cyclic peptide shows that two of the three disulfide distances (Cys(11)-Cys(23) and Cys(17)-Cys(29)) are anticorrelated within ∼1 μs of bridge formation or dissolution: when the peptide is in nativelike structures and one of the distances shortens to allow bond formation, the other tends to lengthen. Simulations over longer timescales, when the denatured state is less structured, do not show the anticorrelation. We propose that the native state contains structural elements that frustrate one another's folding, and that the two bridges are critical for snapping the frustrated native structure into place. In contrast, the Cys(4)-Cys(21) bridge is predicted to form together with either of the other two bridges. Indeed, experimental chromatography and nuclear magnetic resonance data show that an engineered peptide with the Cys(4)-Cys(21) bridge deleted can still fold into its near-native structure even in its noncyclic form, confirming the lesser role of the Cys(4)-Cys(21) bridge. The results highlight the importance of disulfide bridges in a small bioactive peptide to bring together frustrated structure in addition to maintaining protein structural stability. PMID:27119635

    International Nuclear Information System (INIS)

    Using data from the TMX-U diagnostic system, the production of sloshing ions has already been verified and the formation of electron thermal barriers is presently being investigated on the Tandem Mirror Experiment-Upgrade (TMX-U) at Lawrence Livermore National Laboratory. The TMX-U diagnostics are made up of the earlier TMX complement of diagnostics that determine confinement, microstability, and low-frequency stability, plus diagnostic instrumentation that measures electron parameters associated with mirror-confined electrons. This paper describes the three subsystems within the TMX-U diagnostic system: (1) the diagnostic facility (shot leader console, data cable system, and diagnostic timing system); (2) the individual diagnostic instruments that measure plasma and machine parameters; and (3) the data-acquisition and -analysis computer

    FEL hardware includes undulators, alignment systems, electron beam diagnostics, and mechanical and vacuum systems. While most FEL{close_quote}s employ conventional undulators, there is some interest in novel types, particularly where conventional designs cannot be used, as at very short periods and high fields. For these areas, superconducting technology is indicated. The most serious issue facing long FEL undulators is that of alignment; mechanical techniques may not be accurate enough, and beam-based strategies must be considered. To maintain alignment and control the electron trajectory, beam position monitors with micron precision are required. Beam size monitors are also required to assure control of emittance. The talks given in the working group sessions touch on undulators, alignment, and electron beam diagnostics, and they are summarized here. {copyright} {ital 1997 American Institute of Physics.}

    The distance radiation waves that supersonically propagate in optically thick, diffusive media are energy sensitive. A blast wave can form in a material when the initially diffusive, supersonic radiation wave becomes transonic. Under specific conditions, the blast wave is visible with radiography as a density perturbation. [Peterson et al., Phys. Plasmas 13, 056901 (2006)] showed that the time-integrated drive energy can be measured using blast wave positions with uncertainties less than 10% at the Z Facility. In some cases, direct measurements of energy loss through diagnostic holes are not possible with bolometric and x-ray radiometric diagnostics. Thus, radiography of high compression blast waves can serve as a complementary technique that provides time-integrated energy loss through apertures. In this paper, we use blast waves to characterize the energy emerging through a 2.4 mm aperture and show experimental results in comparison to simulations. PMID:19044574

    In this paper, a novel approach to modeling and diagnosing the cardiovascular system is introduced. A model exhibits a subset of the dynamics of the cardiovascular behavior of an individual by using a recurrent artificial neural network. Potentially, a model will be incorporated into a cardiovascular diagnostic system. This approach is unique in that each cardiovascular model is developed from physiological measurements of an individual. Any differences between the modeled variables and the variables of an individual at a given time are used for diagnosis. This approach also exploits sensor fusion to optimize the utilization of biomedical sensors. The advantage of sensor fusion has been demonstrated in applications including control and diagnostics of mechanical and chemical processes.

    The definitive diagnosis of neurologic conditions in cats, as well as other species, has been greatly facilitated by rapid development of new techniques. In some cases, these developments have involved refinements of existing methods, whereas in others, essentially new techniques have evolved. Diagnostic tests developed in earlier years also continue to be of value. The application of many of these techniques is illustrated throughout this text. In this chapter, attention is focused on certain particularly valuable tests

  12. Dosimetry in diagnostic radiology

    International Nuclear Information System (INIS)

    Dosimetry is an area of increasing importance in diagnostic radiology. There is a realisation amongst health professionals that the radiation dose received by patients from modern X-ray examinations and procedures can be at a level of significance for the induction of cancer across a population, and in some unfortunate instances, in the acute damage to particular body organs such as skin and eyes. The formulation and measurement procedures for diagnostic radiology dosimetry have recently been standardised through an international code of practice which describes the methodologies necessary to address the diverging imaging modalities used in diagnostic radiology. Common to all dosimetry methodologies is the measurement of the air kerma from the X-ray device under defined conditions. To ensure the accuracy of the dosimetric determination, such measurements need to be made with appropriate instrumentation that has a calibration that is traceable to a standards laboratory. Dosimetric methods are used in radiology departments for a variety of purposes including the determination of patient dose levels to allow examinations to be optimized and to assist in decisions on the justification of examination choices. Patient dosimetry is important for special cases such as for X-ray examinations of children and pregnant patients. It is also a key component of the quality control of X-ray equipment and procedures.

    2000-01-01

    The Front End of the Spallation Neutron Source (SNS) extends from the Ion Source (IS), through a 65 keV LEBT, a 402.5 MHz RFQ, a 2.5 MeV MEBT, ending at the entrance to the DTL. The diagnostics suite in this space includes stripline beam position and phase monitors (BPM), toroid beam current monitors (BCM), and an emittance scanner. Provision is included for beam profile measurement, either gas fluorescence, laser-based photodissociation, or a crawling wire. Mechanical and electrical design and prototyping of BPM and BCM subsystems are proceeding. Significant effort has been devoted to packaging the diagnostic devices in minimal space. Close ties are maintained to the rest of the SNS effort, to ensure long term compatibility of interfaces and in fact share some design work and construction. The data acquisition, digital processing, and control system interface needs for the BPM, BCM, and LEBT diagnostic are similar, and we are committed to using an architecture common with the rest of the SNS collaboration.

    The Spallation Neutron Source (SNS) accelerator systems will deliver a 1.0 GeV, 1.4 MW proton beam to a liquid mercury target for neutron scattering research. The accelerator complex consists of a 1 GeV linear accelerator, an accumulator ring and associated transport lines. The SNS diagnostics platform is PC-based running Windows XP Embedded for its OS and LabVIEW as its programming language. Coordinating timing among the various diagnostics instruments with the generation of the beam pulse is a challenging task that we have chosen to divide into three phases. First, timing was derived from VME based systems. In the second phase, described in this paper, timing pulses are generated by an in house designed PCI timing card installed in ten diagnostics PCs. Using fan-out modules, enough triggers were generated for all instruments. This paper describes how the Timing NAD (Network Attached Device) was rapidly developed using our NAD template, LabVIEW's PCI driver wizard, and LabVIEW Channel Access library. The NAD...

  16. Diagnostics for Developing Countries

    Directory of Open Access Journals (Sweden)

    Ruth McNerney

    2015-05-01

    Full Text Available Improving the availability of high quality diagnostic tests for infectious diseases is a global priority. Lack of access by people living in low income countries may deprive them of life saving treatment and reduces opportunities to prevent onward transmission and spread of the disease. Diagnostic laboratories are often poorly resourced in developing countries, and sparsely distributed. Improved access may be achieved by using tests that do not require laboratory support, including rapid tests for use at the point-of-care. Despite increased interest, few new in vitro diagnostic (IVD products reach the majority populations in low income countries. Barriers to uptake include cost and lack of robustness, with reduced test performances due to environmental pressures such as high ambient temperatures or dust. In addition to environmental factors test developers must consider the local epidemiology. Confounding conditions such as immunosuppression or variations in antigen presentation or genotype can affect test performance. Barriers to product development include access to finance to establish manufacturing capacity and cover the costs of market entry for new devices. Costs and delays may be inflated by current regulatory preregistration processes to ensure product safety and quality, and more harmonized approaches are needed.

  17. [Acromegaly: reducing diagnostic delay].

    Science.gov (United States)

    Giustina, Andrea

    2016-08-01

    Diagnostic delay of acromegaly is still very relevant (6-8 years on average) without substantial changes in last twenty years. Clinical impact of this diagnostic delay is significant: tumor growth (2/3 of the patients at diagnosis bear a pituitary macroadenoma), development of irreversible complications (arthropathy, sleep apnea) and in all increased mortality. Reasons for this delay are related to the disease itself (facial and acral changes are very slow and subtle) but also to medical unawareness. Simple tools based on a few sufficiently sensitive and specific signs and symptoms which can trigger the diagnostic suspect would be useful in clinical practice. Global evaluation during follow-up (tumor volume, signs and symptoms, complications, circulating levels of growth hormone and its peripheral mediator IGF-I) has become crucial for the therapeutic decision making. In this regard, tools like SAGIT are now under validation and are expected to improve management of acromegaly. In fact, in the last 30 years there has been a relevant growth of the medical options to treat acromegaly and in the near future there will be an expansion of the medical options. This will greatly help the needed personalization of treatment which necessarily should consider patient convenience and preference and control of complications such as diabetes mellitus.

  18. IS WHITE-COLLAR CRIMINALITY CLOSER TO THE RATIONAL MODEL THAN ANY OTHER TYPE MODEL?

    Directory of Open Access Journals (Sweden)

    Jacob RUB

    2016-03-01

    Full Text Available The basic premise is that white-collar felons are making non-rational decisions. To our opinion, they are not making decisions according to a calculation of profit or loss from perpetration of a crime as it was stated earlier in the scientific literature. In relation to the above mentioned premises, an illegal behavior is an occasion of a white-collar felon deciding to take the law into his own hands while taking risks. Naturally, the level of values and personality of the felon constitute a significant factor. Our current study offers an examination of deterring through a prism of the white-collar felon, who makes the decision to perpetrate a crime according to irrational components as well.White-collar crime, as family violence, and other socially harmful behaviors, is often excluded from examination. Of our opinion all the rational, social, biological, etc. theories of crimes, are the base of the reasons to make an offence, but in reality, the implementation of white-collar criminality closer to the non-rational model than any other type model. People are seen as less than fully rational. Often they do not make decisions that would appear to be in their own best interest for a variety of reasons. First, people do not always have all of the information they need to make informed decisions, and even if they do, may not have the capacity to optimally process that information. The personalities, experiences and options that of human beings given the choice in life, that it is quite naive to assume that we will all assess the situation similarly and arrive at similar choices. Many criminal events appear not to be very rational choices at all, or at least reflect patterns of decision making quite different from those more typically seen among law-abiding citizens. Ближе ли беловоротничковая преступность к рациональной модели, нежели к другим типам моделе

  19. Gender equity and tobacco control: bringing masculinity into focus.

    Science.gov (United States)

    Morrow, Martha; Barraclough, Simon

    2010-03-01

    Gender is a key but often overlooked--determinant of tobacco use, especially in Asia, where sex-linked differences in prevalence rates are very large. In this article we draw upon existing data to consider the implications of these patterns for gender equity and propose approaches to redress inequity through gender-sensitive tobacco control activities. International evidence demonstrates that, in many societies, risk behaviours (including tobacco use) are practised substantially more by men and boys, and are also viewed as expressions of masculine identity. While gender equity focuses almost exclusively on the relative disadvantage of girls and women that exists in most societies, disproportionate male use of tobacco has profound negative consequences for men (as users) and for women (nonusers). Surprisingly, health promotion and tobacco control literature rarely focus on the role of gender in health risks among boys and men. However, tobacco industry marketing has masterfully incorporated gender norms, and also other important cultural values, to ensure its symbols are context-specific. By addressing gender-specific risks within the local cultural context--as countries are enjoined to do within the Framework Convention's Guiding Principles--it may be possible to accelerate the impact of mechanisms such as tobacco pricing, restrictions on marketing, smoking bans and provision of accurate information. It is essential that we construct a new research-to-policy framework for gender-sensitive tobacco control. Successful control of tobacco can only be strengthened by bringing males, and the concept of gender as social construction, back into our research and discussion on health and gender equity.

  20. Equity and what secondary science teachers bring to the classroom

    Science.gov (United States)

    Austin, Barbara Anne

    The demographics of people working in science-based careers do not match the demographics of the larger society. In particular, people who self-identify as Hispanic are underrepresented among working scientists. One reason may be the influence of formal schooling and more specifically, the behaviors of teachers in secondary science classrooms. This study looks at the practices of eight secondary science teachers at two schools at which 62% of the enrolled students declare their ethnicity as Hispanic. All of the teachers have at least three years of experience. Through interviews with the teachers, classroom observation, and interviews with other faculty, this research elucidates typical behaviors and attitudes surrounding teaching science in these settings. In spite of having a deficit view of their students, they all express interest in and concern about the students they teach. Their characterizations of teaching practices and classroom behaviors do not incorporate strategies designed to promote content learning through culturally relevant curriculum. Instead, they use mainstream-situated approaches that develop science content knowledge, vocabulary, procedures, and skills targeted toward high achievement on state and district standardized tests leading toward graduation or success in college. These approaches are consistent with a view of equity that increases the participation of underrepresented groups in science based careers in that it gives students the skills and knowledge they will need in order to successfully pursue these careers. Additionally, they behave in ways that are consistent with equitable strategies such as using inquiry based teaching, serving as role models, and providing a structured learning environment. This research informs the literature base for instructional systems designers by identifying what that teachers situated in culturally diverse classrooms bring to professional development programs targeted toward making secondary science

    There's an unsung hero in your organization. It's the person who's bringing in new ideas from the outside about how to manage better. These aren't your product and service innovators--those people are celebrated loudly and often. This is the manager who, for instance, first uttered the phrase "balance scorecard" in your hallways, or "real options," or "intellectual capital." Managerial innovation is an increasingly important source of competitive advantage--especially given the speed with which product innovations are copied--but it doesn't happen automatically. It takes a certain kind of person to welcome new management ideas and usher them into an organization. The authors recently studied 100 such people to find out how they translate new ideas into action in their organizations. They discovered that they are a distinct type of practitioner; that is to say, they resemble their counterparts in other organizations more than they resemble their own colleagues, and they share a common way of working. "Idea practitioners," as the authors call them, begin by scouting for ideas. All of them are avid readers of management literature and enthusiastic participants in business conferences; many are friendly with business gurus. Once they've identified an idea that seems to hold promise, they tailor it to fit their organizations' specific needs. Next, they actively sell the idea--to senior executives, to the rank and file, to middle managers. And finally, they get the ball rolling by participating in small-scale experiments. But when those take off, they get out of the way and let others execute. In this article, the authors identify the characteristics of idea practitioners and offer strategies for managing them wisely.

    Automating prelaunch diagnostics for launch vehicles offers three potential benefits. First, it potentially improves safety by detecting faults that might otherwise have been missed so that they can be corrected before launch. Second, it potentially reduces launch delays by more quickly diagnosing the cause of anomalies that occur during prelaunch processing. Reducing launch delays will be critical to the success of NASA's planned future missions that require in-orbit rendezvous. Third, it potentially reduces costs by reducing both launch delays and the number of people needed to monitor the prelaunch process. NASA is currently developing the Ares I launch vehicle to bring the Orion capsule and its crew of four astronauts to low-earth orbit on their way to the moon. Ares I-X will be the first unmanned test flight of Ares I. It is scheduled to launch on October 27, 2009. The Ares I-X Ground Diagnostic Prototype is a prototype ground diagnostic system that will provide anomaly detection, fault detection, fault isolation, and diagnostics for the Ares I-X first-stage thrust vector control (TVC) and for the associated ground hydraulics while it is in the Vehicle Assembly Building (VAB) at John F. Kennedy Space Center (KSC) and on the launch pad. It will serve as a prototype for a future operational ground diagnostic system for Ares I. The prototype combines three existing diagnostic tools. The first tool, TEAMS (Testability Engineering and Maintenance System), is a model-based tool that is commercially produced by Qualtech Systems, Inc. It uses a qualitative model of failure propagation to perform fault isolation and diagnostics. We adapted an existing TEAMS model of the TVC to use for diagnostics and developed a TEAMS model of the ground hydraulics. The second tool, Spacecraft Health Inference Engine (SHINE), is a rule-based expert system developed at the NASA Jet Propulsion Laboratory. We developed SHINE rules for fault detection and mode identification. The prototype

    Nanotechnology represents an area of particular promise and significant opportunity across multiple scientific disciplines. Ongoing nanotechnology research ranges from the characterization of nanoparticles and nanomaterials to the analysis and processing of experimental data seeking correlations between nanoparticles and their functionalities and side effects. Due to their special properties, nanoparticles are suitable for cellular-level diagnostics and therapy, offering numerous applications in medicine, e.g. development of biomedical devices, tissue repair, drug delivery systems and biosensors. In nanomedicine, recent studies are producing large amounts of structural and property data, highlighting the role for computational approaches in information management. While in vitro and in vivo assays are expensive, the cost of computing is falling. Furthermore, improvements in the accuracy of computational methods (e.g. data mining, knowledge discovery, modeling and simulation) have enabled effective tools to automate the extraction, management and storage of these vast data volumes. Since this information is widely distributed, one major issue is how to locate and access data where it resides (which also poses data-sharing limitations). The novel discipline of nanoinformatics addresses the information challenges related to nanotechnology research. In this paper, we summarize the needs and challenges in the field and present an overview of extant initiatives and efforts.

    International Nuclear Information System (INIS)

    The Hybrid Reactor(HR) can be considered an attractive actinide-burner or a fusion assisted transmutation for destruction of transuranic(TRU) nuclear waste. The hybrid reactor has two important subsystems: the tokamak neutron source and the blanket which includes a fuel zone where the TRU are placed and a tritium breeding zone. The diagnostic system for a HR must be as simple and robust as possible to monitor and control the plasma scenario, guarantee the protection of the machine and monitor the transmutation.

  7. Plasma diagnostics in industry

    International Nuclear Information System (INIS)

    Plasma processing forms an invaluable part of semiconductor device manufacturing. For the most part, commercial tools have relied on an empirical process for their evolution and relied exclusively on plasma characterization only at the development stage. As this industry advances there is the need to provide non-invasive plasma characterization and diagnostics on the processing equipment, in order to provide more control over the plasma properties. We outline some of the typical configurations used in the industry and describe two of the measurement techniques we have developed for the characterization of these industrial plasma sources.

    Full Text Available The location is part of the Vienna River Valley, known as "Wiental", one of the most dissonant, incongruous, and contested areas of Vienna. Depending on one’s perspective, the Vienna River Valley can be viewed as a transit corridor, an unresolved urban area, an urban interface, an inter- zone, an infrastructure bundle, an ugly wound in the urban landscape, a socially charged boundary, etc. We started the project with urban pattern analyses on different scales: the scale of the city, the scale of Wiental (from Schönbrunn to Hofburg and on a minor scale, i.e. the scale of the project.The analysis showed that Wiental constitutes the main connection between the city centre and suburbia and the countryside in the background of the city. With its clear morphological importance, it could become a green axis of the city, a pleasant place for people, rather than having only an infrastructural role. Our concept is to bring new character to Wiental by making it a pedestrian- and cyclist-friendly green axis. Our initial goal was to reduce car traffic. We proposed introducing a park-and-ride system, which would become a point of transfer where car traffic is replaced by public transport and cycle traffic. Through the afforestation of Wiental, the area could become a park or recreational route, and the quality of life in the area would improve.An important aspect of the project was dealing with the Danube. We proposed to manage the flood peaks by introducing a dam, and after the point of regulation, we arranged the River into two levels: an ambient upper flow and infrastructural lower flow in the existing channel. Also, by rearranging "Naschmarkt" with the Danube uncovered, we predicted an extension of tourism from the city centre to Schönbrunn by bicycle or on foot, which could be followed by an expansion of the public programme. We wanted to show that the Danube, with an appropriate environment, could become a significant element of the city structure.

    The implementation of the EU’s integrative policies has resulted in relatively recent resistance to the integration process. Said popular politicization challenges further prospects for integration as it brings layers of identities to clash. A national identity persists within Member States, which views that boundaries should rest on the state level. This conflicts with the supranational identity implied by EU integration as it often necessitates the removal of national barriers. It is argued...

  11. Diagnostic approaches for cholangiocarcinoma

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    Cholangiocarcinomas arise from the epithelial cells of the bile ducts and are associated with poor prognosis. Despite new diagnostic approaches, the definite diagnosis of this malignancy continues to be challenging. Cholangiocarcinomas often grow longitudinally along the bile duct rather than in a radial direction. Thus, large tumor masses are frequently absent and imaging techniques, including ultrasound, CT, and MRI have only limited sensitivity. Tissue collection during endoscopic (ERCP) and/or percutaneous transhepatic (PTC) procedures are usually used to confirm a definitive diagnosis of cholangiocarcinoma. However, forceps biopsy and brush cytology provide positive results for malignancy in about only 50% of patients. Percutaneous and peroral cholangioscopy using fiber-optic techniques were therefore developed for direct visualization of the biliary tree, yielding additional information about endoscopic appearance and tumor extension, as well as a guided biopsy acquistion. Finally, endoscopic ultrasonography (EUS) complements endoscopic and percutaneous approaches and may provide a tissue diagnosis of tumors in the biliary region through fine- needle aspiration. In the future, new techniques allowing for early detection, including molecular markers, should be developed to improve the diagnostic sensitivity in this increasing tumor entity.

  12. Radiation hardening of diagnostics

    International Nuclear Information System (INIS)

    The world fusion program has advanced to the stage where it is appropriate to construct a number of devices for the purpose of burning DT fuel. In these next-generation experiments, the expected flux and fluence of 14 MeV neutrons and associated gamma rays will pose a significant challenge to the operation and diagnostics of the fusion device. Radiation effects include structural damage to materials such as vacuum windows and seals, modifications to electrical properties such as electrical conductivity and dielectric strength and impaired optical properties such as reduced transparency and luminescence of windows and fiber optics during irradiation. In preparation for construction and operation of these new facilities, the fusion diagnostics community needs to work with materials scientists to develop a better understanding of radiation effects, and to undertake a testing program aimed at developing workable solutions for this multi-faceted problem. A unique facility to help in this regard is the Los Alamos Spallation Radiation Effects Facility, a neutron source located at the beam stop of the world's most powerful accelerator, the Los Alamos Meson Physics Facility (LAMPF). The LAMPF proton beam generates 1016 neutrons per second because of ''spallation'' reactions when the protons collide with the copper nuclei in the beam stop

    NASA's Apollo missions held a place in the mindset of many Americans - we dared to go someplace where humans had never set foot, a place unknown and beyond our imaginations. These early NASA missions and discoveries resulted in an enhanced public understanding of the Moon. Now, with the human element so far removed from space exploration, students must rely on textbooks, TV's, and computers to build their understanding of our Moon. However, NASA educational materials about the Moon are stale and out-of-date. In addition, they do not effectively address 21st Century Skills, an essential for today's classrooms. Here, we present a three-part model for developing opportunities in lunar science education professional development that is replicable and sustainable and integrates NASA mission-derived data (e.g., Moon Mineralogy Mapper (M3)/Chandrayaan-1). I) With the return of high resolution/high spatial data from M3/Chandrayaan-1, we can now better explore and understand the compositional variations on the lunar surface. Data and analysis techniques from the imaging spectrometer are incorporated into the M3 Educator's Guide: Seeing the Moon in a New Light. The guide includes an array of activities and lessons to help educators and students understand how NASA is currently exploring the Moon. The guide integrates NASA maps and data into the interactive lessons, bringing the excitement of scientific exploration and discovery into the classroom. II) Utilizing the M3 Educator's Guide as well as educational activities from more current NASA lunar missions, we offer two sustained professional development opportunities for educators to explore the Moon through interactive and creative strategies. 1) Geology of the Moon, an online course offered through Montana State University's National Teacher Enhancement Network, is a 3-credit graduate course. 2) Fly Me to the Moon, offered through the College of Charleston's Office of Professional Development in Education, is a two

    The Spallation Neutron Source now being built in Oak Ridge, Tennessee, USA, accelerates an H- ion beam to 1000 MeV with an average power of 1.4 MW. The H- beam is then stripped to H+, compressed in a storage ring to a pulse length of 695 ns, and then directed onto a mercury neutron spallation target. Most of the acceleration is accomplished with superconducting rf cavities. The presence of these cavities, the high average beam power, and the large range of beam intensity in the storage ring, provide unique challenges to the beam diagnostics systems. In this talk we will discuss these challenges and some of our solutions, including the laser profile monitor system, the residual gas ionization profile monitors, and network attached devices. Measurements performed using prototype instrumentation will also be presented.

    This paper will focus on the state of development of diagnostics which are expected to provide the information needed for {alpha}- physics studies in the future. Conventional measurement of detailed temporal and spatial profiles of background plasma properties in DT will be essential for such aspects as determining heating effectiveness, shaping of the plasma profiles and effects of MHD, but will not be addressed here. This paper will address (1) the measurement of the neutron source, and hence {alpha}-particle birth profile, (2) measurement of the escaping {alpha}-particles and (3) measurement of the confined {alpha}-particles over their full energy range. There will also be a brief discussion of (4) the concerns about instabilities being generated by {alpha}-particles and the methods necessary for measuring these effects. 51 refs., 10 figs.

    In most competent veterinary diagnostic laboratories, analytical findings are interpreted by the veterinary toxicologist to determine the significance of the finding in view of historic, clinical, and pathologic findings. A veterinary toxicologist also will provide consultation about possible toxic rule-outs for a case, treatment of affected animals, and prevention of additional cases. Once all of the information is available, a complete summary of the findings can be provided to the client. When the procedures outlined are followed, including a systematic approach to collecting all the evidence (historic, clinical, pathologic, and analytic), proper sampling techniques, and good communication between the clinician and the client and laboratory, the usefulness of the toxicology investigation will be maximized.

In FY-92, we worked on projects in seven areas, described in this report: novel photonic detectors; a wideband phase modulator; an optoelectronic terahertz beam system; the fabrication of microelectrode electrochemical sensors; diamond heatsinks; advanced micromachining technologies; and electrophoresis using silicon microchannels.

  19. Molecular diagnostic PCR handbook

    International Nuclear Information System (INIS)

    The uses of nucleic acid-directed methods have increased significantly in the past five years and have made important contributions to disease control country programmes for improving national and international trade. These developments include the more routine use of PCR as a diagnostic tool in veterinary diagnostic laboratories. However, there are many problems associated with the transfer and particularly, the application of this technology. These include lack of consideration of: the establishment of quality-assured procedures, the required set-up of the laboratory and the proper training of staff. This can lead to a situation where results are not assured. This book gives a comprehensive account of the practical aspects of PCR and strong consideration is given to ensure its optimal use in a laboratory environment. This includes the setting-up of a PCR laboratory; Good Laboratory Practice and standardised PCR protocols to detect animal disease pathogens. Examples of Standard Operating Procedures as used in individual specialist laboratories and an outline of training materials necessary for PCR technology transfer are presented. The difficulties, advantages and disadvantages in PCR applications are explained and placed in context with other test systems. Emphasis is placed on the use of PCR for detection of pathogens, with a particular focus on diagnosticians and scientists from the developing world. It is hoped that this book will enable readers from various disciplines and levels of expertise to better judge the merits of PCR and to increase their skills and knowledge in order to assist in a more logical, efficient and assured use of this technology

    2008-09-01

    Autoantibodies play a key role in diagnostic laboratories as markers of autoimmune diseases. In addition to their role as markers they mediate diverse effects in vivo. Autoantibodies with protective effect have been described. Natural protective IgM autoantibodies against tumour-antigens of malignant cells or their precursors may contribute to increased survival rates of carcinoma patients. In a mouse model of systemic lupus erythematosus it has been shown that anti-dsDNA IgM autoantibodies protect from glomerular damage. In contrast, a direct pathogenic role of autoantibodies has been well established e.g. in myasthenia gravis or in Goodpasture syndrome. Similarly autoantibodies against SSA Ro52 are detrimental in neonatal lupus erythematosus with congenital heart block. Moreover, putatively protective autoantibodies may become pathogenic during the course of the disease such as the onconeuronal autoantibodies whose pathogenicity depends on their compartmentalisation. In patients with paraneoplastic syndromes tumour cells express proteins that are also naturally present in the brain. Anti-tumour autoantibodies which temporarily suppress tumour growth can provoke an autoimmune attack on neurons once having crossed the blood-brain barrier and cause specific neurological symptoms. Only a restricted number of autoantibodies are useful follow-up markers for the effectiveness of treatment in autoimmune diseases. Certain autoantibodies hold prognostic value and appear years or even decades before the diagnosis of disease such as the antimitochondrial antibodies in primary biliary cirrhosis or anti-citrullinated protein (CCP)-antibodies in rheumatoid arthritis. It is crucial to know whether the autoantibodies in question recognise linear or conformational epitopes in order to choose the appropriate detection methods. Indirect immunofluorescence microscopy remains a very useful tool for confirmation of results of commercially available immunoassays and for detection of

    2015-05-01

    The field of "salivary diagnostics" includes studies utilizing samples obtained from a variety of sources within the oral cavity. These samples include; whole unstimulated saliva, stimulated whole saliva, duct saliva collected directly from the parotid, submandibular/sublingual glands or minor salivary glands, swabs of the buccal mucosa, tongue or tonsils, and gingival crevicular fluid. Many publications state "we collected saliva from subjects" without fully describing the process or source of the oral fluid. Factors that need to be documented in any study include the time of day of the collection, the method used to stimulate and collect the fluid, and how much fluid is being collected and for how long. The handling of the oral fluid during and post-collection is also critical and may include addition of protease or nuclease inhibitors, centrifugation, and cold or frozen storage prior to assay. In an effort to create a standard protocol for determining a biomarker's origin we carried out a pilot study collecting oral fluid from 5 different sites in the mouth and monitoring the concentrations of pro- and anti-inflammatory cytokines detected using MesoScaleDiscovery (MSD) electrochemiluminesence assays. Our data suggested that 3 of the cytokines are primarily derived from the submandibular gland, while 7 of the cytokines come from a source other than the major salivary glands such as the minor salivary glands or cells in the oral mucosae. Here we review the literature on monitoring biomarkers in oral samples and stress the need for determining the blood/saliva ratio when a quantitative determination is needed and suggest that the term oral diagnostic be used if the source of an analyte in the oral cavity is unknown.

  2. Team building and diagnostic training

    International Nuclear Information System (INIS)

    While developing a commercial training program to improve teamwork in control room crews, General Electric's Nuclear Training Services made an important discovery. Traditional training methods for developing teamwork and enhancing diagnostics capabilities are incomplete. Traditional methods generally help, but fail to fulfill the long-term needs of most teams. Teamwork has been treated as a short-term performance problem. Traditional diagnostic training suffers from a similar problem. Too often, it covers only the basic principles of decision-making, ignoring the development of expert diagnostic capabilities. In response to this discovery, they have developed comprehensive training in Team Building and Diagnostics

    The Z Refurbishment (ZR) Project is a program to upgrade the Z machine at SNL with modern durable pulsed power technology, providing additional shot capacity and improved reliability as well as advanced capabilities for both pulsed x-ray production and high pressure generation. The development of enhanced diagnostic capabilities is an essential requirement for ZR to meet critical mission needs. This report presents a comprehensive plan for diagnostic instrument and infrastructure development for the first few years of ZR operation. The focus of the plan is on: (1) developing diagnostic instruments with high spatial and temporal resolution, capable of low noise operation and survival in the severe EMP, bremsstrahlung, and blast environments of ZR; and (2) providing diagnostic infrastructure improvements, including reduced diagnostic trigger signal jitter, more and flexible diagnostic line-of-sight access, and the capability for efficient exchange of diagnostics with other laboratories. This diagnostic plan is the first step in an extended process to provide enhanced diagnostic capabilities for ZR to meet the diverse programmatic needs of a broad range of defense, energy, and general science programs of an international user community into the next decade.

    2010-01-01

    Full Text Available Postmenopausal bleeding (PMB is a common clinical problem. Patients with PMB have 10%–15% chance of having endometrial carcinoma and therefore the diagnostic workup is aimed at excluding malignancy. Patient characteristics can alter the probability of having endometrial carcinoma in patients with PMB; in certain groups of patients the incidence has been reported to be as high as 29%. Transvaginal sonography (TVS is used as a first step in the diagnostic workup, but different authors have come to different conclusions assessing the accuracy of TVS for excluding endometrial carcinoma. Diagnostic procedures obtaining material for histological assessment (e.g., dilatation and curettage, hysteroscopy, and endometrial biopsy can be more accurate but are also more invasive. The best diagnostic strategy for diagnosing endometrial carcinoma in patients with PMB still remains controversial. Future research should be focussed on achieving a higher accuracy of different diagnostic strategies.

  18. The canonical Luminous Blue Variable AG Car and its neighbor Hen 3-519 are much closer than previously assumed

    The strong mass loss of Luminous Blue Variables (LBVs) is thought to play a critical role in the evolution of massive stars, but the physics of their instability and their place in the evolutionary sequence remains uncertain and debated. A key to understanding their peculiar instability is their high observed luminosity, which for Galactic LBVs often depends on an uncertain distance estimate. Here we report direct distances and space motions of four canonical Milky Way LBVs---AG Car, HR Car, HD 168607, and (the LBV candidate) Hen 3-519---whose parallaxes and proper motions have been provided by the Gaia first data release. Whereas the distances of HR Car and HD 168607 are consistent with those previously adopted in the literature within the uncertainty, we find that the distances to Hen 3-519 and AG Car, both at $\\sim$2 kpc, are much closer than the 6--8 kpc distances previously assumed. For Hen 3-519, this moves the star far from the locus of LBVs on the HR Diagram. AG Car has been considered a defining exam...

  20. Are We Getting Closer to or Farther from Water? Human Population Distance to Water in the USA, 1790- 2010

    Water is an attractive factor when people choose where to live. Early civilizations and modern cities primarily evolved around rivers. In early settlement periods, humans choose to locate close to rivers to satisfy their direct consumptive use as well as for navigation purposes. However, as population, wealth, and technical sophistication grow, the relative importance of proximity to rivers weakens, while agglomeration economic effects of historical established settlements and the indirect amenity value of water grow stronger. The reliance on locally available water decreases such that people are not constrained to live only in water-rich places. In this study, we examined the relationship between water resources (surface river networks and major aquifers) and the human population distribution in the conterminous United States from 1790-2010 to answer the following questions: 1) Are we getting closer to or farther from surface water? 2) How is the relative importance of groundwater changing over time? Our analysis indicated that humans have gotten farther from surface water, especially the arid regions, where the mean human population distance increased steadily from 13km to 26km from 1790 to 2010. However, groundwater became more attractive in determining human population distribution, indicated by rapid growth in population percentage living over major aquifers, especially after 1940. The latter trend is associated with rapid technological development. This study of the relationship between human population and water resources provides policy support for the sustainable management of surface water and groundwater resources.

  1. Atomic Models for Motional Stark Effects Diagnostics

    We present detailed atomic physics models for motional Stark effects (MSE) diagnostic on magnetic fusion devices. Excitation and ionization cross sections of the hydrogen or deuterium beam traveling in a magnetic field in collisions with electrons, ions, and neutral gas are calculated in the first Born approximation. The density matrices and polarization states of individual Stark-Zeeman components of the Balmer {alpha} line are obtained for both beam into plasma and beam into gas models. A detailed comparison of the model calculations and the MSE polarimetry and spectral intensity measurements obtained at the DIII-D tokamak is carried out. Although our beam into gas models provide a qualitative explanation for the larger {pi}/{sigma} intensity ratios and represent significant improvements over the statistical population models, empirical adjustment factors ranging from 1.0-2.0 must still be applied to individual line intensities to bring the calculations into full agreement with the observations. Nevertheless, we demonstrate that beam into gas measurements can be used successfully as calibration procedures for measuring the magnetic pitch angle through {pi}/{sigma} intensity ratios. The analyses of the filter-scan polarization spectra from the DIII-D MSE polarimetry system indicate unknown channel and time dependent light contaminations in the beam into gas measurements. Such contaminations may be the main reason for the failure of beam into gas calibration on MSE polarimetry systems.

    Diagnostics play an essential role for the successful operation of the ITER tokamak. They provide the means to observe control and to measure plasma during the operation of ITER tokamak. The components of the diagnostic system in the ITER tokamak will be installed in the vacuum vessel, in the cryostat, in the upper, equatorial and divertor ports, in the divertor cassettes and racks, as well as in various buildings. Diagnostic components that are placed in a high radiation environment are expected to operate for the life of ITER. There are approx. 45 diagnostic systems located on ITER. Some diagnostics incorporate direct or independently pumped extensions to maintain their necessary vacuum conditions. They require a base pressure less than 10{sup −7} Pa, irrespective of plasma operation, and a leak rate of less than 10{sup −10} Pa m{sup 3} s{sup −1}. In all the cases it is essential to maintain the ITER closed fuel cycle. These directly coupled diagnostic systems are an integral part of the ITER vacuum containment and are therefore subject to the same design requirements for tritium and active gas confinement, for all normal and accidental conditions. All the diagnostics, whether or not pumped, incorporate penetration of the vacuum boundary (i.e. window assembly, vacuum feedthrough etc.) and demountable joints. Monitored guard volumes are provided for all elements of the vacuum boundary that are judged to be vulnerable by virtue of their construction, material, load specification etc. Standard arrangements are made for their construction and for the monitoring, evacuating and leak testing of these volumes. Diagnostic systems are incorporated at more than 20 ports on ITER. This paper will describe typical and particular arrangements of pumped diagnostic and monitored guard volume. The status of the diagnostic vacuum systems, which are at the start of their detailed design, will be outlined and the specific features of the vacuum systems in ports and extensions

    We study the effects of Horndeski models of dark energy on the observables of the large-scale structure in the late time universe. A novel classification into {\\it Late dark energy}, {\\it Early dark energy} and {\\it Early modified gravity} scenarios is proposed, according to whether such models predict deviations from the standard paradigm persistent at early time in the matter domination epoch. We discuss the physical imprints left by each specific class of models on the effective Newton constant $\\mu$, the gravitational slip parameter $\\eta$, the light deflection parameter $\\Sigma$ and the growth function $f\\sigma_8$ and demonstrate that a convenient way to dress a complete portrait of the viability of the Horndeski accelerating mechanism is via two, redshift-dependent, diagnostics: the $\\mu(z)-\\Sigma(z)$ and the $f\\sigma_8(z)-\\Sigma(z)$ planes. If future, model-independent, measurements point to either $\\Sigma-10$ at high redshifts or $\\mu-1>0$ with $\\Sigma-11.5$ then Early dark energy models are definitel...

  4. Moyamoya disease: Diagnostic imaging

    International Nuclear Information System (INIS)

    Moyamoya disease is a progressive vasculopathy leading to stenosis of the main intracranial arteries. The incidence of moyamoya disease is high in Asian countries; in Europe and North America, the prevalence of the disease is considerably lower. Clinically, the disease may be of ischaemic, haemorrhagic and epileptic type. Cognitive dysfunction and behavioral disturbance are atypical symptoms of moyamoya disease. Characteristic angiographic features of the disease include stenosis or occlusion of the arteries of the circle of Willis, as well as the development of collateral vasculature. Currently, magnetic resonance angiography and CT angiography with multi-row systems are the main imaging methods of diagnostics of the entire range of vascular changes in moyamoya disease. The most common surgical treatment combines the direct arterial anastomosis between the superficial temporal artery and middle cerebral, and the indirect synangiosis involving placement of vascularised tissue in the brain cortex, in order to promote neoangiogenesis. Due to progressive changes, correct and early diagnosis is of basic significance in selecting patients for surgery, which is the only effective treatment of the disease. An appropriate qualification to surgery should be based on a comprehensive angiographic and imaging evaluation of brain structures. Despite the rare occurrence of moyamoya disease in European population, it should be considered as one of causes of ischaemic or haemorrhagic strokes, especially in young patients

    Tissue mechanical properties reflect extracellular matrix composition and organization, and as such, their changes can be a signature of disease. Examples of such diseases include intervertebral disk degeneration, cancer, atherosclerosis, osteoarthritis, osteoporosis, and tooth decay. Here we introduce the tissue diagnostic instrument (TDI), a device designed to probe the mechanical properties of normal and diseased soft and hard tissues not only in the laboratory but also in patients. The TDI can distinguish between the nucleus and the annulus of spinal disks, between young and degenerated cartilage, and between normal and cancerous mammary glands. It can quantify the elastic modulus and hardness of the wet dentin left in a cavity after excavation. It can perform an indentation test of bone tissue, quantifying the indentation depth increase and other mechanical parameters. With local anesthesia and disposable, sterile, probe assemblies, there has been neither pain nor complications in tests on patients. We anticipate that this unique device will facilitate research on many tissue systems in living organisms, including plants, leading to new insights into disease mechanisms and methods for their early detection.

    2016-01-01

    Diagnosis of gonorrhoea is an ongoing challenge. The organism is fastidious requiring meticulous collection and transport for successful cultivation. Asymptomatic infections are common which go undetected by conventional methods thereby leading to continued transmission and the risk of complications. The nucleic acid amplification tests, now increasingly used in developed countries, offer improved sensitivity compared to bacterial culture. However, these continue to suffer sequence related problems leading to false positive and false negative results. Further, these cannot be used for generation of data on antibiotic susceptibility because genetic markers of antibiotic resistance to recommended therapies have not been fully characterised. They are unaffordable in a setting like ours where reliance is placed on syndromic approach for sexually transmitted infection (STI) management. The use of syndromic approach has resulted in a considerable decline in the number of Neisseria gonorrhoeae isolates that have been cultured for diagnostic purposes. Many laboratories formerly doing so are no longer performing culture for gonococci, and the basic skills have been lost. There is a need to not only revive this skill but also adopt newer technologies that can aid in accurate diagnosis in a cost-effective manner. There is room for innovation that can facilitate the development of a point-of-care test for this bacterial STI. PMID:27080763

    A complex and multifactorial pathogenesis of itch makes the proper diagnosis of underlying disease a difficult and challenging clinical problem. The examination of every patient with itch should be started by gathering an accurate history. During the anamnesis it is important to obtain data about the beginning of the appearance of symptoms, its location, diurnal variation, and the factors influencing itch perception. After careful anamnesis the patient should undergo a detailed physical examination, with particular attention to the skin in order to look for any signs of skin lesions. Special attention should be paid to distinguish the primary lesion from the changes resulting from scratching. In patients in whom the etiology of the itch cannot be identified on the basis of the medical examination, a panel of primary screen laboratory examination may be required, and if necessary, depending on the results of basic laboratory results and data from medical history, additional diagnostic tests should be considered. In patients in whom an organic cause of itching has not been established, itch is most likely of undetermined origin; however, psychogenic causes should also be suspected and ruled out. In conclusion, it could be stated that itch is a common symptom of many skin diseases, systemic of neurological diseases. Despite the complex etiology of the disease, an exact cause of itch should be searched for in each patient, as successful therapy is largely dependent on the determination of the cause of the itching.

    Full Text Available Autoimmune hepatitis is a chronic hepatitis that occurs in children and adults of all ages. Diagnosis is based upon characteristic serologic and histologic findings and the exclusion of other forms of chronic liver disease. Guidelines issued by the AASLD suggest the following diagnostic considerations: The diagnosis should be made in patients with compatible clinical signs, symptoms, and laboratory abnormalities. Other conditions that can cause chronic hepatitis should be excluded. In unclear cases a standardized scoring system should be used in the assessment. In those who are negative for conventional autoantibodies, additional autoantibodies should be sought. All patients with autoimmune hepatitis and inflammatory bowel disease should undergo cholangiographic studies to exclude primary sclerosing cholangitis.   Scoring systems- A scoring system developed and subsequently revised by the International Autoimmune Hepatitis Group to standardize the diagnosis with using simplified criteria based upon titers of autoantibodies, IgG levels, liver histology, and the exclusion of viral hepatitis. Autoantibodies: assign one point if the ANA or SMA are 1:40 OR assign two points if the ANA or SMA are ≥1:80 (OR if the LKM ≥1:40 OR if the SLA is positive. IgG: assign one point if the IgG is > the upper limit of normal OR assign two points if the IgG is >1.10 times the upper limit of normal. Liver histology: assign one point if the histological features are compatible with autoimmune hepatitis OR two points if the histological features are typical of autoimmune hepatitis. Absence of viral hepatitis A probable diagnosis of autoimmune hepatitis is made if the total points are six, while a definite diagnosis is made if the total points are ≥seven.

    2016-05-01

    We present a new hybrid Cauchy-characteristic evolution scheme that is particularly suited to study gravitational collapse in spherically symmetric asymptotically (global) anti-de Sitter (AdS) spacetimes. The Cauchy evolution allows us to track the scalar field through the different round trips to the AdS boundary, while the characteristic method can bring us very close to the point of formation of an apparent horizon. We describe all the details of the method, including the transition between the two evolution schemes and the details of the numerical implementation for the case of massless scalar fields. We use this scheme to provide more numerical evidence for a recent conjecture on the power law scaling of the apparent horizon mass resulting from the collapse of subcritical configurations. We also compute the critical exponents and echoing periods for a number of critical points and confirm the expectation that their values should be the same as in the asymptotically flat case.

  13. Reporting on the ‘ever closer union’: narrative framing in national news medias and resistance to EU integration

    Andrew Anzur CLEMENT

    2015-06-01

    Full Text Available The implementation of the EU’s integrative policies has resulted in relatively recent resistance to the integration process. Said popular politicization challenges further prospects for integration as it brings layers of identities to clash. A national identity persists within Member States, which views that boundaries should rest on the state level. This conflicts with the supranational identity implied by EU integration as it often necessitates the removal of national barriers. It is argued that this clash becomes activated through the manner in which news is reported in national medias. From this, a model is unpacked, positing the employment of narrative formats that frame events and issues with European aspects in national terms. Thus, media portrays national identity as conflicting legitimately with supranational integration, suggesting resistance to the EU project as the appropriate stance if the clash is to be resolved. Finally, possible application of the model is discussed.

    Cystic Fibrosis (CF) is a rare, multisystem disease leading to significant morbidity and mortality. CF is caused by defects in the cystic fibrosis transmembrane conductance regulator protein (CFTR), a chloride and bicarbonate transporter. Early diagnosis and access to therapies provides benefits in nutrition, pulmonary health, and cognitive ability. Several screening and diagnostic tests are available to support a diagnosis. We discuss the characteristics of screening and diagnostic tests for CF and guideline-based algorithms using these tools to establish a diagnosis. We discuss classification and management of common "diagnostic dilemmas," including the CFTR-related metabolic syndrome and other CFTR-associated diseases. PMID:26857766

    Blastocystis spp. are widely prevalent extra cellular, non-motile anerobic protists that inhabit the gastrointestinal tract. Although Blastocystis spp. have been associated with gastrointestinal symptoms, irritable bowel syndrome and urticaria, their clinical significance has remained controversial. We established an ex vivo mouse explant model to characterize adhesion in the context of tissue architecture and presence of the mucin layer. Using confocal microscopy with tissue whole mounts and two axenic isolates of Blastocystis spp., subtype 7 with notable differences in adhesion to intestinal epithelial cells (IEC), isolate B (ST7-B) and isolate H (more adhesive, ST7-H), we showed that adhesion is both isolate dependent and tissue trophic. The more adhesive isolate, ST7-H was found to bind preferentially to the colon tissue than caecum and terminal ileum. Both isolates were also found to have mucinolytic effects. We then adapted a DSS colitis mouse model as a susceptible model to study colonization and acute infection by intra-caecal inoculation of trophic Blastocystis spp.cells. We found that the more adhesive isolate ST7-H was also a better colonizer with more mice shedding parasites and for a longer duration than ST7-B. Adhesion and colonization was also associated with increased virulence as ST7-H infected mice showed greater tissue damage than ST7-B. Both the ex vivo and in vivo models used in this study showed that Blastocystis spp. remain luminal and predominantly associated with mucin. This was further confirmed using colonic loop experiments. We were also successfully able to re-infect a second batch of mice with ST7-H isolates obtained from fecal cultures and demonstrated similar histopathological findings and tissue damage thereby coming closer to proving Koch's postulates for this parasite.

    Rapid and effective hemostasis at femoral puncture sites minimizes both the hospital stay and patient discomfort. Therefore, a variety of arterial closure devices have been developed to facilitate the closure of femoral arteriotomy. The objective of this prospective study was to compare the efficacy of two different closure devices; a collagen plug device (Angio-Seal) and a suture-mediated closure device (the Closer S). From March 28, 2003 to August 31, 2004, we conducted a prospective study in which 1,676 cases of 1,180 patients were treated with two different types of closure device. Angio-Seal was used in 961 cases and the Closer S in 715 cases. The efficacy of the closure devices was assessed, as well as complications occurring at the puncture sites. Successful immediate hemostasis was achieved in 95.2% of the cases treated with Angio-Seal, and in 89.5% of the cases treated with the Closer S ({rho} < 0.05). The rates of minor and major complications occurring between the two groups were not significantly different. In the Closer S group, we observed four major complications (0.6%), that consisted of one massive retroperitoneal hemorrhage (surgically explored) and three pseudoaneurysms. In the Angio-Seal group, we observed three major complications (0.3%) that consisted of one femoral artery occlusion, one case of infection treated with intravenous antibiotics and one pseudoaneurysm. The use of Angio-Seal was found to be more effective than that of the Closer S with regard to the immediate hemostasis of the femoral puncture sites. However, we detected no significant differences in the rate at which complications occurred.

    Free Electron Lasers (FEL) present a unique set of beam parameters to the diagnostics suite. The FEL requires characterization of the full six dimensional phase space of the electron beam at the wiggler and accurate alignment of the electron beam to the optical mode of the laser. In addition to the FEL requirements on the diagnostics suite, the Jefferson Lab FEL is operated as an Energy Recovered Linac (ERL) which imposes additional requirements on the diagnostics. The ERL aspect of the Jefferson Lab FEL requires that diagnostics operate over a unique dynamic range and operate with simultaneous transport of the accelerated and energy recovered beams. This talk will present how these challenges are addressed at the Jefferson Lab FEL.

  2. Plasma diagnostics and atomic processes

    International Nuclear Information System (INIS)

    Spectroscopic plasma diagnostics with the use of atomic processes are discussed relating to three subjects in the followings. i) Time resolved X-ray spectra of titanium helium-like ions from tokamaks. X-ray spectra observed from tokamak plasmas are analysed with a non-ionization equilibrium model which could explain the time behavior of both spectra and ion abundances. ii) Line intensity ratios of OV ions for temperature and density diagnostics. Intensity ratios of emission lines from OV ions are calculated for use in temperature and density diagnostics. The line emissions from a tokamak are analysed for the diagnostics of plasma periphery. iii) Collisional processes in hot dense plasmas. The collisional ladder-like excitation and ionization in a hot dense plasma are discussed for the dielectronic states. This process enhances the excitation rate coefficients and decreases the resonance contributions to the excitation cross section. (author)

    2012-01-01

    Saliva is an important body fluid for diagnostic purposes. Glycoproteins, glucose, steroids, DNA, and other molecules of diagnostic value are found in saliva. It is easier to collect as compared to blood or urine. Unfortunately, saliva also contains large numbers of bacteria that can release enzymes, which can degrade proteins and nucleic acids. These degradative enzymes destroy or reduce saliva s diagnostic value. This innovation describes the formulation of a chemical preservative that prevents microbial growth and inactivates the degradative enzymes. This extends the time that saliva can be stored or transported without losing its diagnostic value. Multiple samples of saliva can be collected if needed without causing discomfort to the subject and it does not require any special facilities to handle after it is collected.

  7. Validation scheme for diagnostic tests

    International Nuclear Information System (INIS)

    The aim was to develop a scheme for the validation of assays developed in the research laboratory for the successful transfer and implementation in the diagnostic laboratory. Although logistically, temporally and economically challenging, proper validation minimizes the chance of failure and increases the possibility of successful transfer and implementation in the diagnostic laboratory. A properly validated assay, which includes good design, good quality control and good documentation, reduces the chances of liability and increases confidence in the assay both nationally and internationally

By consciously following a process when ordering tests, physicians may improve the effectiveness and efficiency of the...

  9. Dilemmas in diagnostics and therapy of rolandic epilepsy

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Introduction. It is considered that around 20%-30% of patients of all ages and in all continents have wrong epilepsy diagnoses. Diagnostic and consequential therapeutic errors appear, most often, when an adequate diagnostics is not applied. Benign focal epilepsy of childhoods with centrotemporal spikes-rolandic epilepsy, brings very often to diagnostic and therapeutic problems because of persistence of epilepticforms changes in an electroencephalography (EEG recording, several years after establishment of good control over seizures. Case report. We presented 8.5 years-old girl, with the first and the only epileptic seizure at the age of 5, during her sleep. With a clear correlation of EEG record, benign rolandic epilepsy was diagnosed, so the therapy with valproate was introduced. There were no seizures after three years of its implementation. Because of epileptic-forms changes that still persisted in EEG record during her sleep, it was suggested to further use valproate. However, after reconsidering all circumstances it was concluded that the AED should bee slowly reduced up to its exclusion. After a complete stoppage of the therapy, the patient did not have any epileptic seizure for nine months, although EEG still remained pathologically changed during her sleep. Conclusion. A changed EEG record in a patient with rolandic epilepsy must not be a predictor of continuation of antiepileptic drugs therapy, after 2-3 years of successful seizures remission.

    A good diagnostic procedure avoids wasting medical resources, is easy to use, resists contamination, and provides accurate information quickly to allow for rapid follow-up therapies. We developed a novel diagnostic procedure using a "cotton-based diagnostic device" capable of real-time detection, i.e., in vitro diagnostics (IVD), which avoids reagent contamination problems common to existing biomedical devices and achieves the abovementioned goals of economy, efficiency, ease of use, and speed. Our research reinforces the advantages of an easy-to-use, highly accurate diagnostic device created from an inexpensive and readily available U.S. FDA-approved material (i.e., cotton as flow channel and chromatography paper as reaction zone) that adopts a standard calibration curve method in a buffer system (i.e., nitrite, BSA, urobilinogen and uric acid assays) to accurately obtain semi-quantitative information and limit the cross-contamination common to multiple-use tools. Our system, which specifically targets urinalysis diagnostics and employs a multiple biomarker approach, requires no electricity, no professional training, and is exceptionally portable for use in remote or home settings. This could be particularly useful in less industrialized areas. PMID:25393975

    Full Text Available Abstract Background Vertigo and dizziness are symptoms which are reported frequently in clinical practice. We aimed to develop diagnostic indices for four prevalent vertiginous diseases: benign paroxysmal positional vertigo (BPPV, Menière's disease (MD, vestibular migraine (VM, and phobic postural vertigo (PPV. Methods Based on a detailed questionnaire handed out to consecutive patients presenting for the first time in our dizziness clinic we preselected a set of seven questions with desirable diagnostic properties when compared with the final diagnosis after medical workup. Using exact logistic regression analysis diagnostic scores, each comprising of four to six items that can simply be added up, were built for each of the four diagnoses. Results Of 193 patients 131 questionnaires were left after excluding those with missing consent or data. Applying the suggested cut-off points, sensitivity and specificity were 87.5 and 93.5% for BPPV, 100 and 87.4% for MD, 92.3 and 83.7% for VM, 73.7 and 84.1% for PPV, respectively. By changing the cut-off points sensitivity and specificity can be adjusted to meet diagnostic needs. Conclusions The diagnostic indices showed promising diagnostic properties. Once further validated, they could provide an ease to use and yet flexible tool for screening vertigo in clinical practice and epidemiological research.

  14. Moving Closer to the Collapse of a Massless Scalar Field in Spherically Symmetric Anti-de Sitter Spacetimes

    CERN Document Server

    Santos-Oliván, Daniel

    2016-01-01

    We present a new hybrid Cauchy-characteristic evolution method that is particularly suited for the study of gravitational collapse in spherically-symmetric asymptotically (global) Anti-de Sitter (AdS) spacetimes. The Cauchy evolution allows us to track the scalar field through the different bounces off the AdS boundary while the characteristic method can bring us very close to the point of formation of an apparent horizon. Here, we describe all the details of the method, including the transition between the two evolution schemes and the details of the numerical implementation for the case of massless scalar fields. We use this scheme to provide more numerical evidence for a recent conjecture on the power-law scaling of the apparent horizon mass resulting from the collapse of subcritical configurations. We also compute the critical exponents and echoing periods for a number of critical points and confirm the expectation that their values should be the same as in the asymptotically-flat case.

  15. How does a change in the control room design affect diagnostic strategies in nuclear power plants?

    International Nuclear Information System (INIS)

    Recently, main control rooms have been considerably changed by modern computer techniques. Some of the features that distinguish digital control rooms from conventional, analog rooms in nuclear power plants include advanced alarm systems, graphic information display systems, computerized procedure systems, and soft control. These features can bring changes in operator tasks, changing the characteristics of tasks or creating new tasks for operators. It is especially expected that these features may bring out changes in the operator's diagnostic tasks and strategies in a digital control room as compared with an analog control room. This study investigates the differences in the operator's diagnostic tasks and strategies in analog and digital control rooms. This study also attempts to evaluate how new systems in a digital control room affect diagnostic strategies. Three different approaches, which are complementary, are used to identify diagnostic strategies in the digital control room and in the analog control room: (1) observation in the simulator, (2) interview with operators, and (3) a literature review. The results show that the digital control room introduces new diagnosis strategies compared with the analog control room while also changing the characteristics of the strategies, mostly by gaining more support from the computerized system.

    An increased attention to tungsten material is related to a fact that it became a main candidate for the plasma facing material in ITER and future fusion reactor. The proposed work refers to the studies of W influence on the plasma performances by developing new detectors based on Gas Electron Multiplier GEM) technology for tomographic studies of tungsten transport in ITER-oriented tokamaks, e.g. WEST project. It presents current stage of design and developing of cylindrically bent SXR GEM detector construction for horizontal port implementation. Concept to overcome an influence of constraints on vertical port has been also presented. It is expected that the detecting unit under development, when implemented, will add to the safe operation of tokamak bringing creation of sustainable nuclear fusion reactors a step closer.

  19. Course of radiological protection and safety in the medical diagnostic with X-rays

    International Nuclear Information System (INIS)

    The obtention of images of human body to the medical diagnostic is one of the more old and generalized applications for X-ray. Therefore the design and performance of equipment and installations as well as the operation procedures must be oriented toward safety with the purpose to guarantee this radiological practice will bring a net positive benefit to the society. Given that in Mexico only exists the standardization related to source and equipment generators of ionizing radiation in the industrial area and medical therapy, but not so to the medical diagnostic area it is the purpose of this work to present those standards related with this application branch. Also it is presented the preparation of a manual for the course named Formation of teachers in radiological protection and safety in the X-ray medical diagnostic in 1997 which was imparted at ININ.

    Point-of-care (POC) diagnostics brings tests nearer to the site of patient care. The turnaround time is short, and minimal manual interference enables quick clinical management decisions. Growth in POC diagnostics is being continuously fueled by the global burden of cardiovascular and infectious diseases. Early diagnosis and rapid initiation of treatment are crucial in the management of such patients. This review provides the rationale for the use of POC tests in acute coronary syndrome, heart failure, human immunodeficiency virus, and tuberculosis. We also consider emerging technologies that are based on advanced nanomaterials and microfluidics, improved assay sensitivity, miniaturization in device design, reduced costs, and high-throughput multiplex detection, all of which may shape the future development of POC diagnostics.

    2006-08-01

    The area of optical and laser diagnostics continues to expand and develop, and is now an essential part of many fields in engineering. Indeed it is one of the most interdisciplinary of the topics of today's research, impacting upon areas from fundamental physics to IT and encompassing a wide number of specific fields in engineering today. The proceedings of this, the second International Conference on Optical and Laser Diagnostics (ICOLAD 2005), follows upon the very successful first conference held in 2002, and reflects in its content many of the developments in this area since that time. The aim of a Conference which is an international forum for new ideas and developments in this exciting branch of optical engineering continues, building upon the foundation of research in optical diagnostics and optical sensing for a number of industrial and biomedical application areas at the City University, London. The Conference was structured into a number of sessions, held over three days in London, with the contributed talks led by invited papers from many internationally known and respected experts in their field from the UK, mainland Europe, the United States and Japan. The material covered includes such major themes as laser diagnostics, reciprocating engine-related applications and flow velocity measurement, extending to encompass, for example, biomedical and structural monitoring using advanced optical techniques. The papers draw their authority from the reputations of the authors and the groups and companies internationally that they represent and this volume brings together a valuable cross-section of such world-leading research. The local Organizing Committee would like to acknowledge and thank the industrial sponsors of the Conference and the members of the local and the International Steering Committee for their contribution to the success of this Conference. In particular thanks are due to Ms Claire Pantlin and the Institute of Physics for their work to make

    An important challenge facing many deregulated electricity markets is dealing with the increasing penetration of intermittent generation. Simulation studies have pointed to the advantages of trading closer to real-time with large amounts of intermittent generation. Using Danish data, I show that, as expected, shortfalls increase the probability of trade on the shortterm market. But in the period studied between 2010 and 2012 surpluses are shown to decrease the probability of trade. This unexp...

  3. Fetal exposure in diagnostic radiology

    International Nuclear Information System (INIS)

    The problem of possible radiation damage to the fetus or embryo as a result of diagnostic radiography during pregnancy, particularly in the early stages, is discussed. Recommendations of therapeutic abortion after fetal exposure require an adequate knowledge of the doses involved. In the absence of actual dose measurements or estimates, approximate exposure levels may be determined from the literature. A summary of published values for radiography involving the lower abdomen is given. Data is also presented from a series of fetal exposures resulting mostly from routine diagnostic radiography when pregnancy was not known at the time but was established later. Results of actual dose measurements using a phantom and of dose calculations based on published values are in reasonable agreement indicating that literature values of dose provide a satisfactory alternative to measurement. These data suggest that diagnostic radiography rarely, if ever, results in fetal exposures high enough to justify therapeutic abortion. (author)

    Yeamans, C B; Bleuel, D L; Bernstein, L A

    2012-10-01

    The NIF neutron activation diagnostic suite relies on removable activation samples, leading to operational inefficiencies and a fundamental lower limit on the half-life of the activated product that can be observed. A neutron diagnostic system measuring activation of permanently installed samples could remove these limitations and significantly enhance overall neutron diagnostic capabilities. The physics and engineering aspects of two proposed systems are considered: one measuring the (89)Zr/(89 m)Zr isomer ratio in the existing Zr activation medium and the other using potassium zirconate as the activation medium. Both proposed systems could improve the signal-to-noise ratio of the current system by at least a factor of 5 and would allow independent measurement of fusion core velocity and fuel areal density.

    Full Text Available Introduction Vestibular schwannoma (acoustic neuroma is a rare, but important cause of sensorineural hearing loss. Patients with asymmetric hearing loss, or unilateral tinnitus should be evaluated expeditiously, to prevent further neurological damage. Audiologic diagnostics Audiologic diagnostics represents the basic diagnosis for early detection of vestibular schwannoma. Patients with vestibular schwannomas may present with a variety of clinical features, including retrocochlear pattern of sensorineural hearing loss. Supraliminary audiometry, tympano- metry, stapedius reflex and otoacoustic emissions as well as vestibular response to caloric testing are methods for selection of patients with suspicion of this tumor. Conclusion The golden standard for audiologic diagnostics of vestibular schwannoma is BAEP (Brainstem Auditory Evoked Potentials. Patients with pathological findings of BAEP should undergo MRI of the posterior fossa. Gadolinium-enhanced magnetic resonance imaging is the best and final tool for making a diagnosis of vestibular schwannoma.

  7. HSX hardware, control and diagnostics

    International Nuclear Information System (INIS)

    The HSX Helically Symmetric Stellarator has been operational for the last year, making plasmas at 0.5T using 28 GHz ECH. During this phase of operation, hardware, machine diagnostics, and plasma diagnostics have been continually implemented to improve machine operation and control, and plasma diagnostic capabilities. This paper will provide and overview of the basic machine control concepts, some details of the He glow discharge cleaning methods used to provide density control under plasma operation, and some details of the LabViewR (National Instruments) and SLC interfaced machine control, timing and diagnostics. Low-level machine operation (coil deflection, ground currents, vacuum base pressures and contaminants, etc.), motor generator, Gyrotron, coil cooling and temperature monitoring is also performed using the LabView/SLC combination; more of which is planned for the ensuing months. Diagnostic implementation, from 288 GHz microwave interferometer, diamagnetic loop signals, optical and x-ray diagnostics, probes, etc., are primarily interfaced using LabView A/D, digital and analog I/O, and timing cards controlled by PC computers: all of which save the data to a PC based data storage site. A ten-chord fir Thomson Scattering system and a multichannel ECE system are under construction for operation in the near future, again with primary control and data interface planned for incorporation into the PC based system. A SQL database is currently under implementation to improve overall data searching capabilities and accessibility, and to facilitate data backup and protection. Both MatLabR and IDLR are currently used for data analysis and presentation, which will be maintained through the database implementation.

    Advances in microwave technology have made it possible to develop a new generation of microwave imaging diagnostics for measuring the parameters of magnetic fusion devices. The most prominent of these diagnostics is electron cyclotron emission imaging (ECE-I). After the first generation of ECE-I diagnostics utilized at the TEXT-U, RTP and TEXTOR tokamaks and the LHD stellarator, new systems have recently come into operation on ASDEX-UG and DIII-D, soon to be followed by a system on KSTAR. The DIII-D and KSTAR systems feature dual imaging arrays that observe different parts of the plasma. The ECE-I diagnostic yields two-dimensional movies of the electron temperature in the plasma and has given already new insights into the physics of sawtooth oscillations, tearing modes and edge localized modes. Microwave Imaging Reflectometry (MIR) is used on LHD to measure electron density fluctuations. A pilot MIR system has been tested at TEXTOR and, based on the promising results, a new system is now under design for KSTAR. The system at TEXTOR was used to measure the plasma rotation velocity. The system at KSTAR and also the one on LHD will be/are used for measuring the profile of the electron density fluctuations in the plasma. Other microwave imaging diagnostics are phase imaging interferometry, and imaging microwave scattering. The emphasis in this paper will be largely focused on ECE-I. First an overview of the advances in microwave technology are discussed, followed by a description of a typical ECE-I system along with some typical experimental results. Also the utilization of imaging techniques in other types of microwave diagnostics will be briefly reviewed. This document is composed of the slides of the presentation. (authors)

  9. Using the 2011 Mw9.0 Tohoku earthquake to test the Coulomb stress triggering hypothesis and to calculate faults brought closer to failure

    Science.gov (United States)

    Toda, Shinji; Lin, Jian; Stein, Ross S.

    2011-01-01

    The 11 March 2011 Tohoku Earthquake provides an unprecedented test of the extent to which Coulomb stress transfer governs the triggering of aftershocks. During 11-31 March, there were 177 aftershocks with focal mechanisms, and so the Coulomb stress change imparted by the rupture can be resolved on the aftershock nodal planes to learn whether they were brought closer to failure. Numerous source models for the mainshock have been inverted from seismic, geodetic, and tsunami observations. Here, we show that, among six tested source models, there is a mean 47% gain in positively-stressed aftershock mechanisms over that for the background (1997-10 March 2011) earthquakes, which serve as the control group. An aftershock fault friction of 0.4 is found to fit the data better than 0.0 or 0.8, and among all the tested models, Wei and Sladen (2011) produced the largest gain, 63%. We also calculate that at least 5 of the seven large, exotic, or remote aftershocks were brought ≥0.3 bars closer to failure. With these tests as confirmation, we calculate that large sections of the Japan trench megathrust, the outer trench slope normal faults, the Kanto fragment beneath Tokyo, and the Itoigawa-Shizuoka Tectonic Line, were also brought ≥0.3 bars closer to failure.

    2010-01-01

    The purpose of a diagnostic test is to confirm or rule out disease or to increase or decrease the probability of disease. Only a few tests can separate all patients into those with and without a disease (true positive and true negative test). Usually there will be some false test results (false...... positive and false negative). Traditionally, the four test results are given in a 2 by 2 table, and the terms sensitivity, specificity, and predictive values defined. The influence of the prevalence of the disease in question on the relative distribution of the four test results is not obvious....... This technical note brings a new illustration of the relative distribution of the four test results at prevalence from 0-1. The figure facilitates the understanding of the impact prevalence has on the predictive values of a clinical test....

    In this chapter we review numerous diagnostics capable of measurements at or near the first wall, many of which contribute information useful for safe operation of a tokamak. There are sections discussing infrared cameras, visible and VUV cameras, pressure gauges and RGAs, Langmuir probes, thermocouples, and erosion and deposition measurements by insertable probes and quartz microbalance. Also discussed are dust measurements by electrostatic detectors, laser scattering, visible and IR cameras, and manual collection of samples after machine opening. In each case the diagnostic is discussed with a view toward application to a burning plasma machine such as ITER.

  13. Diagnostic imaging of the prostate

    International Nuclear Information System (INIS)

    Modalities for the diagnostic imaging of the prostate are surveyed. Transrectal sonography is thought to be the best method for the purpose, because of its non-invasive nature, fine picture quality, sufficient reproductivity and less expensive cost. Up-to-date utilizations of the method are described, such as diagnostic capability, staging, monitoring, screening and intervention. CT is less effective but MRI is promising to visualize internal structure inside the prostate. Two very new techniques, namely, ultrasonic Doppler color flow mapping and positron emission CT (PET), of which application to the prostate is being investigated originally in our laboratory, are introduced.

    Full Text Available Exposing K–12 students to cutting edge science that impacts their daily lives can bring classroom lessons to life. Citizen-science projects are an excellent way to bring high-level science to the classroom and help satisfy one of the cornerstone concepts of the Next Generation Science Standards (NGSS, “engaging in practices that scientists and engineers actually use.” This can be a daunting task for teachers who may lack the background or resources to integrate these projects into the classroom. This is where scientific societies such as the American Society for Microbiology (ASM can play a critical role. ASM encourages its members to engage with the K–12 community by providing networking opportunities and resources for ASM members and K–12 teachers to work together to bring microbiology into the classroom.

    Highlights: • This paper describes about the ITER diagnostics ex-vessel engineering services. • It describes various diagnostics systems, its location and its environment. • Diagnostics interfaces with other services such as the buildings, HVAC, electrical services, cooling water, vacuum, liquid and gas distribution. • All the interfaces with these services are identified and defined. • Buildings services for diagnostics, such as penetrations, local shielding, embedment and temperature control are discussed. -- Abstract: Extensive diagnostics systems will be installed on the ITER machine to provide the measurements necessary to control, evaluate and optimize plasma performance in ITER and to further the understanding of plasma physics. These include measurements of temperature, density, impurity concentration, and particle and energy confinement times. ITER diagnostic systems extend from the center of the Tokamak to the various diagnostic areas, where they are controlled and acquired data is processed. This mainly includes the areas such as ports, port cells, gallery, diagnostics enclosures and cubicle areas. The diagnostics port plugs encloses the front end of the diagnostic systems and the diagnostics building houses the diagnostics equipment, instrumentation and control cubicles. There are several systems providing services to diagnostics. These mainly include ITER buildings, electrical power services, cooling water services, Heating Ventilation and Air Conditioning (HVAC), vacuum services, liquid and gas distribution services, cable engineering, de-tritiation systems, control cubicles, etc. Requirements of these service systems have to be defined, even though many of the diagnostics are at an early stage of development. It is a real challenge to define and to design diagnostics systems considering the constraints imposed by these service systems. This paper summarizes the provision of these services to the individual diagnostics and diagnostics areas

  8. A closer look at cognitive control: Differences in resource allocation during updating, inhibition and switching as revealed by pupillometry

    Directory of Open Access Journals (Sweden)

    Eefje eRondeel

    2015-09-01

    Full Text Available The present study investigated resource allocation, as measured by pupil dilation, in tasks measuring updating (2-Back task, inhibition (Stroop task and switching (Number Switch task. Because each cognitive control component has unique characteristics, differences in patterns of resource allocation were expected. Pupil and behavioral data from 35 participants were analysed. In the 2-Back task (requiring correct matching of current stimulus identity at trial p with the stimulus two trials back, p-2 we found that better performance (low total of errors made in the task was positively correlated to the mean pupil dilation during correctly responding to targets. In the Stroop task, pupil dilation on incongruent trials was higher than those on congruent trials. Incongruent versus congruent trial pupil dilation differences were positively related to reaction time differences between incongruent and congruent trials. Furthermore, on congruent Stroop trials, pupil dilation was negatively related to reaction times, presumably because more effort allocation paid off in terms of faster responses. In addition, pupil dilation on correctly-responded-to congruent trials predicted a weaker Stroop interference effect in terms of errors, probably because pupil dilation on congruent trials were diagnostic of task motivation, resulting in better performance. In the Number Switch task we found higher pupil dilation in switch as compared to non-switch trials. On the Number Switch task, pupil dilation was not related to performance. We also explored error-related pupil dilation in all tasks. The results provide new insights in the diversity of the cognitive control components in terms of resource allocation as a function of individual differences, task difficulty and error processing.

    Full Text Available The study will try to perform an in-depth analysis of the measure of compulsory bringing, assessing both the national legislation and the legislation of some European countries, namely: Austria, Bulgaria, Poland and the Netherlands. Due attention will be granted to the provisions of the current Criminal Procedure Code, which entered into force on the 1st of February 2014, as this piece of legislation brings some important changes regarding the compulsory bringing, some of them being the consequence of the convictions of Romania in front of the Strasbourg Court. Also, the paper will focus on case-law established by the European Court of Human Rights regarding articles 3 and 5 relating to the compulsory bringing. To close with, the study will give some conclusions regarding the conformity of the current Criminal Procedure Code of Romania with the standards imposed by the European Convention for the Protection of Human Rights and Fundamental Freedoms and by the case-law of the European Court of Human Rights.

  7. Diagnostic reference levels for diagnostic radiology: French implementation methods

    International Nuclear Information System (INIS)

    ICRP publication 73 (Radiological Protection and Safety in Medicine) introduced the concept of 'diagnostic reference levels' (DRL), for medical exposures specifically. Because dose limits should not be applied for diagnostic or therapeutic irradiation, the approach to radiological protection is slightly different from that in occupational or public exposures. Reference levels, that are neither optimum levels, nor dose limits, are a tool for optimisation. DRL are set for standard procedures, for groups of patients or standard phantom and not for special exposures and individual patients. They act as a test for identifying situations where patient doses are becoming unusually high and local review of procedures and equipment is required. Within the framework of implementation of Directive 97/43, the Health Directorate entrusted its radiation protection agency (past OPRI3, at present time DGSNR3 and IRSN3) to determine the national reference dose levels in diagnostic radiology in close cooperation with relevant scientific and professional societies. The pragmatic way, recommended by European Commission, to assess DRL values is to use the third quartile values observed in wide scale surveys of typical doses for common procedures. In the absence of recent and wide-ranging data for France, in a first step, European DRL have been adopted as starting points. To go further, a campaign of patient dose measurements has been launched by a steering committee (OPRI3, SFR3 and SFPM3) to allow the actual establishment of national reference values and to prepare their periodic review in a continuous process of optimization.

  8. SPECT and FDG-PET in diagnostics of neurolues

    International Nuclear Information System (INIS)

    Syphilis is a recurrent treponematosis of acute and chronic evolution. In general it is either sexually or congenitally transmitted. Primary syphilis appears as a single and painless lesion. Secondary syphilis may manifest years later, the secondary bacteremic stage is accompanied by generalized mucocutaneous lesions. Tertiary disease can be disseminated to bones and virtually any organ, involving principally the ascending aorta and the central nervous system. Nuclear medicine provides diagnostic methods in case of skeletal manifestations by bone scan - identifying periostitis and osteomyelitis. Hepatic gummas can be imaged by 99m-Tc-colloid liver scintigraphy. In neurosyphilis brain perfusion SPECT enables imaging of cerebral involvement by small vessel endartheritis resulting from syphilitic vascular disease. 18-FDG PET is also useful to evaluate neurosyphilis, a reduction of brain glucose consumption is observed. The technique adequately enables imaging of therapeutic response and might be superior to morphologic imaging. We present our experiences with these nuclear medicine methods in patients with neurolues. The incidence of neurolues is estimated at 2 per 100.000 inhabitants worldwide, migration processes might bring a re-emergence of this disease to Austria and other developed countries of the EU. Scintigraphic methods should be kept in mind for diagnostic evaluation of neurosyphilis. (author)

    The diagnostic workup of contact allergy to fragrances must not be limited to patch testing with the two well-established fragrance mixes. False-positive reactions to these mixes occur in up to 50 % of the patch tested patients. For the diagnostic work-up of positive reactions, and in cases of suspected fragrance allergy, patch testing with the single mix components and additional fragrances is mandatory. Frequently sensitizing fragrance materials are the 14 components of the two fragrance mixes and tree moss (Evernia furfuracea), ylang ylang oil (I + II; Cananga odorata), lemongrass oil (Cymbopogon schoenanthus), sandalwood oil (Santalum album), jasmine absolute (Jasminum spp.), and, less frequently, clove oil (Eugenia caryophyllus), cedarwood oil (Cedrus atlantica/deodara, Juniperus virginiana), Neroli oil (Citrus aurantium amara flower oil), salicylaldehyde, narcissus absolute (Narcissus spp.), and patchouli oil (Pogostemon cablin).

    2015-12-01

    Full Text Available Saliva is a readily available oral fluid with many functions, from digestion, maintenance of oral tissues’ integrity, to caries prevention. Changes regarding its secretion may be divided into qualitative and quantitative: both of them are a consequence of certain conditions/diseases (e.g. internal factors or nutrients/drugs ingested (e.g. external factors. During the last 15 years, technological advances gave a significant momentum to utilization of saliva as a diagnostic tool. Analysis of saliva, just like the blood analysis, has two main objectives: to identify the subjects suffering from a certain disorder, and to follow the development and progress of therapy. This paper provides an overview of possibilities for the use of saliva for diagnostic purposes and gives specific examples of some clinical investigations, with the final aim to stimulate the use of this noninvasive means for the health care promotion.

    Computed tomography (CT) has been used as a diagnostic technique in various urological diseases. Here demonstrated is a case of ureteral incontinence with double renal pelvis whose upper one has ectopic ureteral orifice. Also a case of ureteral stricture in transplanted kidney and three cases of uric acid calculi are demonstrated. CT provides accurate information in each diagnostic procedure. The use of CT in the diagnosis of urinary stones is estimated. CT number of 75 stones with single component shows specific distribution in relation to the component; ex. calcium stones: 900 - 1000, cystine: 700 - 800, struvite: 600 - 700, uric acid: 400 - 500. Structure and component of the stone is easily demonstrated by CT, especially about nonopaque calculi, whose image is positively displayed only by CT.

    2015-10-06

    Huntington disease (HD) is caused by expansion of a CAG trinucleotide repeat in the first exon of the Huntingtin (HTT) gene. Molecular testing of Huntington disease for diagnostic confirmation and disease prediction requires detection of the CAG repeat expansion. There are three main types of HD genetic testing: (1) diagnostic testing to confirm or rule out disease, (2) presymptomatic testing to determine whether an at-risk individual inherited the expanded allele, and (3) prenatal testing to determine whether the fetus has inherited the expanded allele. This unit includes protocols that describe the complementary use of polymerase chain reactions (PCR) and Southern blot hybridization to accurately measure the CAG trinucleotide repeat size and interpret the test results. In addition, an indirect linkage analysis that does not reveal the unwanted parental HD status in a prenatal testing will also be discussed.

    Samaranayake, Lakshman

    2007-10-01

    The use of saliva as a diagnostic fluid for various human ailments is gaining popularity as it offers distinct advantages over serum. These include the non-invasive nature of saliva collection compared with phlebotomy, simplicity of collection even for individuals with a modest training and the cost-effective applicability for screening large populations. Whole saliva is most frequently used for diagnosis of systemic diseases since it is readily collected and contains serum constituents while gland-specific saliva is useful for investigating pathology of major salivary glands. Broadly, saliva analysis is currently used for the diagnosis of infectious and malignant diseases, hereditary disorders, autoimmune diseases, and endocrine disorders, as well as for the assessment of therapeutic drug levels, particularly in monitoring drug abuse. This review addresses the current status of salivary diagnostics and their future potential.

    Chronic pancreatitis is defined as a continuous inflammatory pancreatic disease, one characterized by irreversible morphological changes, often associates with pain and sometimes with the loss of endocrine and exocrine function. As a histological confirmation of chronic pancreatitis is often unavailable, the diagnosis is traditionally based on imaging methods such as computerized tomography (CT) or endoscopic retrograde cholangiopancreatography (ERCP), and recently magnetic resonance cholangiopancreatography (MRCP) as a noninvasive alternative to ERCP. Developments in the classification system of CP include the Marseille classification of 1963 which offered histopathologic criteria for CP, the Cambridge classification of 1984 which introduced imaging features of computed tomography (CT), transabdominal ultrasound (TUS) and endoscopic retrograde cholangiopancreatography (ERCP) for classification of CP as well as Rosemont classification system of 2007 which presented the endoscopic ultrasonography diagnosis of CP. Endoscopic ultra-sonography (EUS) was first introduced as a diagnostic method for evaluation of pancreatic disease in 1986. It has experienced significant improvements since then and allowed for an alternative approach in diagnosing patients with pancreatic diseases. In patients with suspected pancreatic masses EUS-guided fine needle aspiration (EUS-FNA) is the best method for obtaining tissue diagnosis and differentiating CP from pancreatic carcinoma. The recent studies indicate that EUS is the method of choice when compared with other imaging methods such as ERCP because it frequently provides more accurate diagnostics. The aim of this review is to discuss the findings in endoscopic diagnostics up to the present moment and to indicate advantages, limitations and possible complications along with the current recommendations in CP diagnostics.

    The goal of the Plasma Liner eXperiment PLX-alpha at Los Alamos National Laboratory is to establish the viability of creating a spherically imploding plasma liner for MIF and HED applications, using a spherical array of supersonic plasma jets launched by innovative contoured-gap coaxial plasma guns. PLX- α experiments will focus in particular on establishing the ram pressure and uniformity scalings of partial and fully spherical plasma liners. In order to characterize these parameters experimentally, a suite of diagnostics is planned, including multi-camera fast imaging, a 16-channel visible interferometer (upgraded from 8 channels) with reconfigurable, fiber-coupled front end, and visible and VUV high-resolution and survey spectroscopy. Tomographic reconstruction and data fusion techniques will be used in conjunction with interferometry, imaging, and synthetic diagnostics from modeling to characterize liner uniformity in 3D. Diagnostic and data analysis design, implementation, and status will be presented. Supported by the Advanced Research Projects Agency - Energy - U.S. Department of Energy.

    We built a system to guide decisions regarding the amount of genomic sequencing required to develop diagnostic DNA signatures, which are short sequences that are sufficient to uniquely identify a viral species. We used our existing DNA diagnostic signature prediction pipeline, which selects regions of a target species genome that are conserved among strains of the target (for reliability, to prevent false negatives) and unique relative to other species (for specificity, to avoid false positives). We performed simulations, based on existing sequence data, to assess the number of genome sequences of a target species and of close phylogenetic relatives (''near neighbors'') that are required to predict diagnostic signature regions that are conserved among strains of the target species and unique relative to other bacterial and viral species. For DNA viruses such as variola (smallpox), three target genomes provide sufficient guidance for selecting species-wide signatures. Three near neighbor genomes are critical for species specificity. In contrast, most RNA viruses require four target genomes and no near neighbor genomes, since lack of conservation among strains is more limiting than uniqueness. SARS and Ebola Zaire are exceptional, as additional target genomes currently do not improve predictions, but near neighbor sequences are urgently needed. Our results also indicate that double stranded DNA viruses are more conserved among strains than are RNA viruses, since in most cases there was at least one conserved signature candidate for the DNA viruses and zero conserved signature candidates for the RNA viruses.

    2015-07-01

    Full Text Available Making final decisions on the occupational etiology of musculoskeletal diseases is often difficult and problematic at every stage of the diagnostic procedure. Taking into account the need to facilitate decision-making about the causal relationship between the diagnosed disease entity and the working conditions guidelines for the recognition of work-related musculoskeletal diseases have been developed. This paper presents the guidelines for the diagnosis of occupational etiology of humeral epicondylitis, one of the most common occupational disease of the musculoskeletal system in Poland. The developed guidelines have been based on the literature data concerning occupational risk factors of humeral epicondylitis, workload classification, including repetitive movements, awkward postures, and force. Some criteria applied in ergonomic evaluation methods were also included. The presented diagnostic guidelines define approximate benchmarks for stating (after excluding non-occupational etiology that the identified humeral epicondylitis, is related to the way of working. Crucial work factors that should be analyzed include an operating time of movements overloading tendons connecting to the epicondyle, repetition and force used to perform occupational activities. The developed guidelines are aimed to facilitate occupational physicians diagnostic and certification procedures in case of humeral epicondylitis and determination whether there is a likelihood of its occupational etiology.

    The DNA microarray technology is currently a useful biomedical tool which has been developed for a variety of diagnostic applications. However, the development pathway has not been smooth and the technology has faced some challenges. The reliability of the microarray data and also the clinical utility of the results in the early days were criticized. These criticisms added to the severe competition from other techniques, such as next-generation sequencing (NGS), impacting the growth of microarray-based tests in the molecular diagnostic market.Thanks to the advances in the underlying technologies as well as the tremendous effort offered by the research community and commercial vendors, these challenges have mostly been addressed. Nowadays, the microarray platform has achieved sufficient standardization and method validation as well as efficient probe printing, liquid handling and signal visualization. Integration of various steps of the microarray assay into a harmonized and miniaturized handheld lab-on-a-chip (LOC) device has been a goal for the microarray community. In this respect, notable progress has been achieved in coupling the DNA microarray with the liquid manipulation microsystem as well as the supporting subsystem that will generate the stand-alone LOC device.In this chapter, we discuss the major challenges that microarray technology has faced in its almost two decades of development and also describe the solutions to overcome the challenges.

  19. Experimental and numerical studies on liquid wicking into filter papers for paper-based diagnostics

    International Nuclear Information System (INIS)

    Paper-based diagnostics have shown promising potential applications in human disease surveillance and food safety analysis at the point-of-care (POC). The liquid wicking behavior in diagnostic fibrous paper plays an important role in development of paper-based diagnostics. In the current study, we performed experimental and numerical research on the liquid wicking height and mass with three width strips into filter paper. The effective porosity could be conveniently measured in the light of the linear correlation between wicking height and mass by the experimental system. A modified model with considering evaporation effect was proposed to predict wicking height and mass. The predicted wicking height and mass using the evaporation model was much closer to the experimental data compared with the model without evaporation. The wicking speed initially decreased significantly and then maintained at a constant value at lower level. The evaporation effect tends to reduce the wicking flow speed. More wicking mass could be obtained at larger strip width but the corresponding reagent loss became significant. The proposed model with evaporation paved a way to understanding the fundamental of fluid flow in diagnostic paper and was essential to provide meaningful and useful reference for the research and development of paper-based diagnostics devices. - Highlights: • A model with considering evaporation was proposed to predict wicking height and mass. • Flow characteristics of filter paper were experimentally and theoretically studied. • Effective porosity could be conveniently measured by the experimental platform. • The evaporation effect tended to reduce the wicking flow speed

  20. Infectious Disease Management through Point-of-Care Personalized Medicine Molecular Diagnostic Technologies

    Directory of Open Access Journals (Sweden)

    Luc Bissonnette

    2012-05-01

    Full Text Available Infectious disease management essentially consists in identifying the microbial cause(s of an infection, initiating if necessary antimicrobial therapy against microbes, and controlling host reactions to infection. In clinical microbiology, the turnaround time of the diagnostic cycle (>24 hours often leads to unnecessary suffering and deaths; approaches to relieve this burden include rapid diagnostic procedures and more efficient transmission or interpretation of molecular microbiology results. Although rapid nucleic acid-based diagnostic testing has demonstrated that it can impact on the transmission of hospital-acquired infections, we believe that such life-saving procedures should be performed closer to the patient, in dedicated 24/7 laboratories of healthcare institutions, or ideally at point of care. While personalized medicine generally aims at interrogating the genomic information of a patient, drug metabolism polymorphisms, for example, to guide drug choice and dosage, personalized medicine concepts are applicable in infectious diseases for the (rapid identification of a disease-causing microbe and determination of its antimicrobial resistance profile, to guide an appropriate antimicrobial treatment for the proper management of the patient. The implementation of point-of-care testing for infectious diseases will require acceptance by medical authorities, new technological and communication platforms, as well as reimbursement practices such that time- and life-saving procedures become available to the largest number of patients.

    Full Text Available Changes in the soon to be released Diagnostic Statistical Manual (DSM – 5 (American Psychiatric Association, 2012 bring new opportunities for occupational therapy, but the profession must prepare for the impact these changes forecast. While well positioned to capitalize on newly defined specifications of Autism Spectrum Disorders (ASD and the elevation of sensory processing difficulties to a core feature of the disorder, the profession must be alert to the potential downside of the pending changes. The more stringentdiagnostic rubric will likely exclude a significant number of individuals currently eligible for therapeutic and academic services. Autism will be defined as a neurodevelopmental disorder that must be identifiable before early childhood (age 5, even if it is not detected until later as a result of environmental factors (minimal social demands, support from caretakers, etc.. The new diagnostic criteria will add the explicit recognition of sensory behaviors within a subdomain of stereotyped motor, verbal, and sensory-based behaviors and researchers suggest only 60% of those who currently meet the threshold for an autism spectrum diagnosis will continue to meet criteria under the new categorization. The proposed changes will likely encourage researchers to use greater specificity when recruiting sample populations and, as a result, help to determine interventions that are most advantageous for specific subtypes. Addressing sensory processing in thediagnostic criteria may authorize interventions aimed specifically towards reduction of sensory-related disabilities through remediation, environmental support, or parent education while simultaneously calling upon us to deliver evidence for Ayres’ sensory integration® (ASI approaches. The change also presents anurgent call to our profession to promote the unique scientific contributions occupational therapy makes for individuals with ASD, their families, and their educational contexts

    2016-08-01

    Fecal incontinence is defined by the unintentional loss of solid or liquid stool, and anal incontinence includes leakage of gas and / or fecal incontinence. Anal-fecal incontinence is not a diagnosis but a symptom. Many patients hide the problem from their families, friends, and even their doctors. Epidemiologic studies indicate a prevalence between 7-15 %, up to 30 % in hospitals and up to 70 % in longterm care settings. Anal-fecal incontinence causes a significant socio-economic burden. There is no widely accepted approach for classifying anal-fecal incontinence available. Anal-fecal continence is maintained by anatomical factors, rectoanal sensation, and rectal compliance. The diagnostic approach comprises muscle and nerve injuries by iatrogenic, obstetric or surgical trauma, descending pelvic floor or associated diseases. A basic diagnostic workup is sufficient to characterize the different manifestations of fecal incontinence in most of the cases. This includes patient history with a daily stool protocol and digital rectal investigation. Additional investigations may include anorectal manometry, anal sphincter EMG, conduction velocity of the pudendal nerve, needle EMG, barostat investigation, defecography and the dynamic MRI. Therapeutic interventions are focused on the individual symptoms and should be provided in close cooperation with gastroenterologists, surgeons, gynecologists, urologists, physiotherapeutics and psychologists (nutritional-training, food fibre content, pharmacological treatment of diarrhea/constipation, toilet training, pelvic floor gymnastic, anal sphincter training, biofeedback). Surgical therapy includes the STARR operation for rectoanal prolapse and sacral nerve stimulation for chronic constipation and anal-fecal incontinence. Surgery should not be applied unless the diagnostic work-up is complete and all conservative treatment options failed. PMID:27557074

  11. PDR diagnostics study with CLOUDY

    Institute of Scientific and Technical Information of China (English)

    Rui Xue; Maohai Huang

    2009-01-01

    A series of plane-parallel photodissociation region (PDR) models are calculated using the spectral synthesis code CLOUDY. These models span a wide range of physical conditions, with gas densities of n = 102 - 106 cm-3 and incident far-ultraviolet (FUV) fields of G0 = 100 - 106 (where Go is the FUV flux in units of the local interstellar value), which are comparable with various astrophysical environments from interstellar diffuse clouds to the dense neutral gas around galactic compact HII regions. Based on the calculated results, we study the thermal balance of PDR gas and the emissions of [ CII ], [ CI ] and [ OI ] fine-structure lines under different physical conditions. The intensities and strength ratios of the studied lines, which are frequently used as PDR diagnostics, are presented using contour diagrams as functions of n and Go. We compare the calculated PDR surface gas temperatures T8 with those from Kaufman et al. and find that Ts from our models are systematically higher over most of the adopted n-G0 parameter space. The predicated line intensities and ratios from our work and those from Kaufman et al. can be different by a factor greater than 10, and such large differences usually occur near the border of our parameter space. The different methods of treating the dust grain physics, the change of H2 formation and dissociation rates, and the improvement in the radiation transfer of line emissions in our CLOUDY models are likely to be the major reasons for the divergences. Our models represent an up-to-date treatment of PDR diagnostic calcula- tions and can be used to interpret observational data. Meanwhile, the uncertainties in the treatment of microphysics and chemical processes in PDR models have significant effects on PDR diagnostics.

  13. Optoelectronic tweezers for medical diagnostics

    Science.gov (United States)

    Kremer, Clemens; Neale, Steven; Menachery, Anoop; Barrett, Mike; Cooper, Jonathan M.

    2012-01-01

    Optoelectronic tweezers (OET) allows the spatial patterning of electric fields through selected illumination of a photoconductive surface. This enables the manipulation of micro particles and cells by creating non-uniform electrical fields that then produce dielectrophoretic (DEP) forces. The DEP responses of cells differ and can produce negative or positive (repelled or attracted to areas of high electric field) forces. Therefore OET can be used to manipulate individual cells and separate different cell types from each other. Thus OET has many applications for medical diagnostics, demonstrated here with work towards diagnosing Human African Trypanosomiasis, also known as sleeping sickness.

    Pedophilia is a disorder of sexual preference that increases the risk for committing sexual offenses against children. Consequently, pedophilia is not only relevant in psychiatric therapy and prognostics, but also greatly influences the public attitude towards criminality. Public opinion seems to equate pedophilia with child sexual abuse and vice versa which leads to stigmatization of patients and may impede treatment. The present paper provides information on recent studies on the potential origins of the disorder and introduces new diagnostic methods. Moreover, the article presents estimates on the prevalence of pedophilic sexual interest.

    Renal colic is a common reason for presentation to emergency departments, and imaging has become fundamental for the diagnosis and clinical management of this condition. Ultrasonography and particularly noncontrast computed tomography have good diagnostic performance in diagnosing renal colic. Radiologic management will depend on the tools available at the center and on the characteristics of the patient. It is essential to use computed tomography techniques that minimize radiation and to use alternatives like ultrasonography in pregnant patients and children. In this article, we review the epidemiology, clinical and radiologic presentations, and clinical management of ureteral lithiasis.

    Laser illumination of tissue results in a characteristic fluorescence emission spectrum whose features depend on the type of tissue, viz., healthy, adenoma or malignant. Hence measurement of the fluorescence is potentially a rapid and reliable diagnostic method. We have applied the technique to thyroid tissues and found that judicious normalization of the fluorescence spectrum reveals a close correlation between spectral shape and tissue type. Hence the pathological state of the tissue can be unambiguously identified from the laser-induced fluorescence spectrum. The method is rapid and portable and is therefore eminently suitable for use during operations.

    Ophthalmic ultrasound is an invaluable tool that provides quick and noninvasive evaluation of the eye and the orbit. It not only allows the clinicians to view structures that may not be visible with routine ophthalmic equipment or neuroimaging techniques but also provides unique diagnostic information in various ophthalmic conditions. In this article, the basic principles of ophthalmic ultrasound and examination techniques are discussed. Its clinical application is illustrated through a variety of ocular pathologic abnormalities (eg, narrow angles, ciliary body tumor, detached retina, choroidal melanoma, and papilledema).

    This book is based on the authors' extensive practical experience in the use of modern ultrasound, and other radiological methods, in the diagnosis of thyroid diseases. The authors have analyzed more than 100,000 ultrasound examinations performed between 1995 and 2008 in patients with thyroid and parathyroid disease, as well as many thousands of diagnostic and therapeutic ultrasound-guided minimally invasive procedures. The opening chapters include discussion of current ultrasound techniques, pitfalls, and the specifics of ultrasound examination of the thyroid in children. Detailed attention is then devoted to findings in the normal thyroid and in the presence of diffuse and focal changes. Further chapters focus on such topics as ultrasound examination after thyroid surgery and ultrasound diagnosis of parathyroid disease, recurrent goiter, and neck masses. Ultrasound-guided minimally invasive techniques, such as fine-needle aspiration biopsy, percutaneous laser ablation, and ethanol and glucocorticoid injections, are considered in depth. This up-to-date and richly illustrated book will interest and assist specialists in ultrasound diagnostics, radiologists, endocrinologists, and neck surgeons. (orig.)

  4. Thematic plan on diagnostic radiology

    International Nuclear Information System (INIS)

    Due to the vital importance of diagnostic radiology in both the diagnosis and management of disease processes, there is a need for a greater coherent international effort to help the developing nations create strategies for the incorporation of imaging into their healthcare systems. To meet the needs of such countries, a comprehensive programme is required to take into consideration the availability of local expertise (medical and technical), the infrastructure (stable electrical supply, water and air-conditioning) and the disease pattern or burden. In short, the total solution requires coordinating the International Atomic Energy Agency efforts with those of other partners. The Agency already has programmes in nuclear medicine and radiation therapy supported by activities in dosimetry and medical physics. Through the Technical Co-operation fund the Agency already supports projects in some areas of diagnostic imaging, dosimetry and radiation protection, but it lacks a comprehensive programme to provide a systematic approach focusing on the medical aspects of imaging science and including all the imaging technologies. Member States require the Agency's assistance in this area since no single UN organisation has the resources or the expertise to do the entire job without help. This document presents the proposed programme strategy and action plan

    The 1s2-1s2l lines are the most intense He-like ions lines. They are used as spectroscopic diagnostics for solar active regions as well as for different laboratory plasmas. Nowadays, it exits very high spectral resolution instruments and, for intense X-ray sources, one can do spectroscopic diagnostics from line ratios. With XMM (RGS) and Chandra (LETGS, HETGS) spectral resolutions and for several atomic elements, it is particularly possible to separate a 3 blended line set, the so-called He-like triplet: Resonance (r), Intercombination (i) and Forbidden (f), which are dominated respectively by lines issued from the following levels : 1s2p 1P1, 1s2p 3P1,2 and 1s2s 3S1. We shall show that the measurement of two different ratios between these 3 lines (R = f/i and G = (f + i)/r) give quantitative informations on the nature of the emitting plasma (photo-ionized or collisional) and on its electronic density and temperature. A more refined analysis must also include satellite line contributions.

    Child sexual abuse is one of the most destructive events for healthy child development. Following psychiatric classification systems, pedophilia must be distinguished from child sexual abuse. Approximately only one half of all child abusers fulfill the diagnostic criteria for pedophilia which is defined as a persistent or dominating sexual preference for prepubescent children characterized by persistent thoughts, fantasies, urges, sexual arousal or behavior. This article describes the diagnostic criteria and potential differential diagnoses as well as epidemiological and etiological findings. From an etiological point of view multifactorial mechanisms are currently considered to be responsible especially genetic factors, learning theoretical and neurobiological factors. Psychotherapeutic and pharmaceutical treatment options will be discussed. According to the current state of knowledge cognitive-behavioral psychotherapy is the method of choice in the treatment of pedophilia and has demonstrated positive treatment effects in meta-analyses regarding relapse prevention. Medicinal treatment of pedophilia is only indicated for severe forms of pedophilia. Important aspects of risk management in the treatment of pedophilia and aspects which must be considered in the forensic psychiatric assessment are presented.

  7. Interprofessional working in diagnostic radiography

    International Nuclear Information System (INIS)

    This paper considers interprofessional working within one diagnostic imaging department. The literature is still divided about the long-term impact of interprofessional learning in pre-registration health and social care education, and its impact on the quality of care provided. When reading the literature about interprofessional working the main topics considered by other authors are team working, communication between professionals, stereotyping and tribalism. The results presented are from an ethnographic study in one department with participant observation and semi-structured interviews. The three main aspects discussed in this paper are; tribalism and culture within the diagnostic radiography profession, communication between different professional groups, and a lack of understanding of the roles of other professional groups. It was evident from the results of this study that tribalism and culture, and a lack of understanding were significant barriers to interprofessional working. It was felt by the authors that pre-registration and post-registration interprofessional education could be significant in changing the culture of the NHS in the future as more professionals learn from and about one another

  8. Diagnostic and therapeutic radiation exposure

    International Nuclear Information System (INIS)

    Diagnostic and therapeutic radiology were studied as possible contaminants in the evaluations of A-bomb survivors in the ABCC-JNIH Adult Health Study for radiation effects. Hiroshima and Nagasaki subjects received X-ray examinations elsewhere within three months of their ABCC visits at rates of 23 and 12%, respectively. Medical X-ray examinations were more frequent among survivors than comparison subjects. Hiroshima and Nagasaki radiologic practice steadily increased since 1948, and differed markedly by city. From 1946-70 the Hiroshima and Nagasaki X-ray bone marrow doses were 2,300 and 1,000 g-rads, respectively. By 1970, cumulated medical X-ray doses approximated A-bomb doses at distances from the hypocenters of 2,000 m in Hiroshima and 2,800 m in Nagasaki. ABCC X-ray examination doses per subject are routinely updated for comparison with A-bomb doses. Each subject's reported fluoroscopy, photofluorography and radiation therapy exposure elsewhere are for future reference. Dental radiography, though increasing, was not currently an important contributor to survivors' overall exposure. Radiation therapy exposures of 137 subjects were confirmed, and doses estimated for most. Two-thirds the treatments were for malignancies; therapy differed markedly by city; and five cancers possibly arose from earlier radiation therapy. This underscores the importance of considering diagnostic and therapeutic radiology when attributing diseases to the atomic bombs. (auth.)

    The decision to treat active tuberculosis (TB) is dependent on microbiological tests for the organism or evidence of disease compatible with TB in people with a high demographic risk of exposure. The tuberculin skin test and peripheral blood interferon-γ release assays do not distinguish active TB from a cleared or latent infection. Microbiological culture of mycobacteria is slow. Moreover, the sensitivities of culture and microscopy for acid-fast bacilli and nucleic acid detection by PCR are often compromised by difficulty in obtaining samples from the site of disease. Consequently, we need sensitive and rapid tests for easily obtained clinical samples, which can be deployed to assess patients exposed to TB, discriminate TB from other infectious, inflammatory or autoimmune diseases, and to identify subclinical TB in HIV-1 infected patients prior to commencing antiretroviral therapy. We discuss the evaluation of peripheral blood transcriptomics, proteomics and metabolomics to develop the next generation of rapid diagnostics for active TB. We catalogue the studies published to date seeking to discriminate active TB from healthy volunteers, patients with latent infection and those with other diseases. We identify the limitations of these studies and the barriers to their adoption in clinical practice. In so doing, we aim to develop a framework to guide our approach to discovery and development of diagnostic biomarkers for active TB. PMID:27005907

    On ITER, front-end components must operate reliably in a hostile environment. Many will be housed in massive port plugs, which also shield the machine from radiation. Multiple diagnostics reside in a single plug, presenting new challenges for developers. Front-end components must tolerate thermally-induced stresses, disruption-induced mechanical loads, stray ECH radiation, displacement damage, and degradation due to plasma-induced coatings. The impact of failures is amplified due to the difficulty in performing robotic maintenance on these large structures. Motivated by needs to minimize disruption loads on the plugs, standardize the handling of shield modules, and decouple the parallel efforts of the many parties, the packaging strategy for diagnostics has recently focused on the use of 3 vertical shield modules inserted from the plasma side into each equatorial plug structure. At the front of each is a detachable first wall element with customized apertures. Progress on US equatorial and upper plugs will be used as examples, including the layout of components in the interspace and port cell regions.

  11. New tuberculosis diagnostics and rollout

    2015-03-01

    Full Text Available Early detection and effective treatment are crucial for tuberculosis control, but global case detection rates remain low. The diagnosis of paediatric and extrapulmonary disease is problematic and there are, as yet, no rapid screening tests to assist active case finding in the community. Progress has been made in clinic-based detection tools with the introduction of Xpert MTB/RIF, a nucleic acid amplification test that combines sample processing and analysis in a single instrument to provide a diagnostic result and detection of resistance to rifampicin in under 2 h. Enthusiasm for Xpert MTB/RIF has been high and global rollout has been facilitated by donor agencies. However, concerns remain about access and sustainability due to the high cost and infrastructure requirements. Although more sensitive than smear microscopy, early studies suggest the impact of the new test on case detection rates and patient survival has been limited. Alternative technologies are being developed, including non-sputum-based tests to assist the detection of extrapulmonary disease. Evaluation studies are needed to provide evidence of the impact of the new technologies on patient outcomes. This will enable appropriate placement of new diagnostic products in the healthcare system to support the control and eventual eradication of tuberculosis disease.

  12. Beam diagnostics with synchrotron radiation

    International Nuclear Information System (INIS)

    Synchrotron radiation is often used to measure the dimensions of an electron beam. The transverse size is obtained from an image of the beam cross section formed by means of the emitted synchrotron radiation. Because of the small natural opening angle the resolution is limited by diffraction. The angular spread of the particles in the beam can be measured by observing the radiation directly. Here, the resolution is limited by the natural opening angle of the emitted light. Measuring both beam cross section and angular spread gives the emittance of the beam. However, in most cases only one of these two parameters is observed and the other deduced from the known particle beam optics at the source of the radiation. Usually one observes radiation emitted in long bending magnets. However, short magnets and undulators are also useful sources for these measurements. For practical reasons the beam diagnostics is carried out using visible or ultraviolet light. This part of the spectrum is usually far below the critical frequency, and corresponding approximations can be applied. Synchrotron radiation is an extremely useful tool for diagnostics in electron (or positron) rings. In some cases it has also served in proton rings using special magnets. (author)

  13. Development of an instrument to measure the clinical learning environment in diagnostic radiology

    International Nuclear Information System (INIS)

    A clinical learning environment survey instrument was developed that provided insights into diagnostic radiology trainees' perceptions of the culture and context of the hospital-based training programme. The survey was completed by trainees allocated to 37 important training hospitals in Australia, New Zealand and Singapore in 2006. The main findings were that most obvious strengths of the diagnostic radiology programme are the wide variety of work-based learning opportunities and the social atmosphere. These were well regarded in all training sites. Work overload was seen as a significant problem in most hospitals and will probably remain a challenge. The areas that are most likely to repay efforts to bring about change are supervision and feedback. The study provides baseline data against which the influence of changes to the training programme may be evaluated.

    The International Conference on Optical and Laser Diagnostics (ICOLAD 2007), held at City University in May 2007, was the third meeting in this well established series, following upon the first in 2002 and the second in 2005. During that time the area of optical and laser diagnostics has continued to develop and to expand with both the changes seen in the technology and the availability of new optical components and laser systems. The field remains one of the most interdisciplinary of the topics of today's research, impacting upon areas from fundamental physics to IT and encompassing a number of different areas in engineering today. These proceedings are a record of current practice in this area from a Conference which remains an international forum for new ideas and developments in this exciting branch of optical engineering. It builds upon the foundation of research in the broad field of optical diagnostics in a number of industrial and biomedical application areas at the City University, London. The Conference was structured into a number of sessions reflecting topical developments in engine research, optical sensing and measurement and biomedical engineering held over three days in London, with the contributed talks led by invited papers from many internationally known and respected experts in their field from mainland Europe, the United States and Japan and the UK. The material covered encompasses such major themes as laser diagnostics, reciprocating engine-related applications and flow velocity measurement, extending to include biomedical and structural monitoring using advanced optical techniques. The papers at this Conference continue to draw their authority from the reputations of the authors and the groups and companies internationally that they represent. This volume brings together a valuable cross-section of world-leading research at the time. The local Organizing Committee would like to acknowledge and thank the industrial sponsors of the Conference

    In this research,a GPA(Gas Path Analysis)diagnostic system enhanced with GPA Index is described for gas path sensor and component fault diagnosis.A method of measurement correction is used in order that the measurement data obtained at un-standard ambient and operating conditions can be used for diagnostic analysis.The developed diagnostic system has been implemented into a Cranfield University gas turbine performance and diagnostic analysis software PYTHIA for gas turbine performance degradation analysis.The developed method and software have been applied to a model aero gas turbine engine to test the effectiveness of the system.The analysis shows that the developed diagnostic system can diagnose degraded sensor and components effectively using performance deviation measured at un-standard ambient and operational conditions.Theoretically,the idea of the diagnostic approach can be applied to different gas turbine engines.

  16. Irradiation effects on plasma diagnostic components

    International Nuclear Information System (INIS)

    One of the most important issues to develop the diagnostics for the experimental thermonuclear reactor such as ITER is the irradiation effects on the diagnostics components. Typical neutron flux and fluence on the first wall are 1 MW/m2 and 1 MWa/m2, respectively for ITER. In such radiation condition, most of the present diagnostics could not survive so that those will be planed to be installed far from the vacuum vessel. However, some diagnostics sensors such as bolometers and magnetic probes still have to be install inside vessel. And many transmission components for lights, wave and electric signals are inevitable even inside vessel. As a part of this R and D program of the ITER Engineering Design Activities (EDA), we carried out the irradiation tests on the basic materials of the transmission components and in-vessel diagnostics sensors in order to identify radiation hardened materials that can be used for diagnostic systems.

    We investigate key features of thrust earthquake triggering, inhibition, and clustering associated with the stress transferred by the 2003 M=6.9 Zemmouri quake on an offshore hidden thrust fault in coastal Algeria. A crucial question is whether the seismic hazard increased on the Boumerdes and Thenia faults, which lie just west of the Zemmouri rupture and only 10-20 km from the city of Algiers. The capital city suffered large damaging quakes in A.D. 1365 and 1716, and is today home to 3 million people. Slip on blind thrust faults tend to increase the stress above the source fault and in much of the surrounding crust, whereas slip on surface-cutting thrust faults drops the stress in most of the adjacent crust. We examined the sensitivity of the imparted stress to different published source models of the 2003 Zemmouri event inferred from geodetic and seismic inversions, and focus here on the robust results. We calculate that the 2003 M=6.9 Zemmouri quake brought the Coulomb stress 1.0 bars closer to failure on the reverse Boumerdes and 0.5 bars closer on the right-lateral Thenia faults that bound the populated Mitidja basin, although the Thenia fault may not be tectonically active. The calculated pattern of the stress increase appears consistent with aftershock distribution determined from double difference earthquake tomography by Ayadi et al. (submitted); both of these faults were illuminated by aftershocks during the first three months of the sequence. The East Sahel and Larbaa faults, which lie further to the west, are calculated to have sustained a weak 0.1-bar stress increase and show no associated aftershocks. We also calculate a 1.0-bar stress increase on the NNW-SSE trending vertical right-lateral Kabyle fault located south of the Zemmouri fault, although there is no evidence of recent Quaternary tectonic movement, no geomorphology typical of active zones, and little seismicity along the Kabyle fault.

    118 adult patients with respiratory, cardiovascular, digestive, urino-genital or endocrinological diseases have been observed. Kirlian diagnostics on palm finger radiation has been used along with common clinico-laboratory methods. Data comparison of these methods showed that Kirlian diagnostics can be used in clinical differential diagnostics as an supplementary method to determine the severity of the pathological process, its pathogenesis, functional state of compensatory reactions. It helps to determine preclinical and residual signs of a disease. PMID:15605819

    A motional Stark effect diagnostic at the tokamak TEXTOR has been constructed and brought recently into operation. In contrast to diagnostics used on other tokamaks, this diagnostic reveals the direction of the magnetic field from the intensity ratio of the π and σ components of the emitted Balmer-α and not from a polarization measurement of a single line. Moreover, the complete spectrum is measured which allows determining the radial position of the measurement, and in principle the radial electric field.

    Development of the target therapies of lung cancer was a rapid process which fundamentally changed the pathological diagnosis as well. Furthermore, molecular pathology became essential part of the routine diagnostics of lung cancer. These changes generated several practical problems and in underdeveloped countries or in those with reimbursement problems have been combined with further challenges. The central and eastern region of Europe are characterized by similar problems in this respect which promoted the foundation of NSCLC Working Group to provide up to date protocols or guidelines. This present paper is a summary of the molecular pathology and target therapy guidelines written with the notion that it has to be upgraded continuously according to the development of the field.

    To the Editor: Referring to a recent special report about the cost analysis of twenty-nine nuclear medicine procedures, I would like to clarify some basic aspects for determining costs of nuclear medicine procedure with various costing methodologies. Activity Based Costing (ABC) method, is a new approach in imaging services costing that can provide the most accurate cost data, but is difficult to perform in nuclear medicine diagnostic procedures. That is because ABC requires determining and analyzing all direct and indirect costs of each procedure, according all its activities. Traditional costing methods, like those for estimating incomes and expenses per procedure or fixed and variable costs per procedure, which are widely used in break-even point analysis and the method of ratio-of-costs-to-charges per procedure may be easily performed in nuclear medicine departments, to evaluate the variability and differences between costs and reimbursement - charges.

    Full Text Available Petroleum hydrocarbons are known as carcinogenic and may contaminate the environment (water, air and soil. In this study, a diagnostic of polluted soils by petroleum hydrocarbons is carried out in order to know the effect of their accumulation as well as their behavior in time. The aging factor, a source of significant changing in hydrocarbon behavior, is integrated on two sites of an industrial refinery as experimental samples. The first site is recently polluted by hydrocarbons while the second is a previously polluted site.The results indicate that the concentration of hydrocarbons on the surface of the first site is greater and remains stable in time, as for the second site, hydrocarbons concentration on the surface is also important and undergoes a weak reduction. At a depth of one meter hydrocarbons exist at a greater concentration. This shows that obstinate hydrocarbons are an environmental danger for fauna and flora.

    1999-06-01

    The Lawrence Livermore National Laboratory Flash X-ray (FXR) machine is being upgraded to produce two pulses. A very fast imaging system has been developed to characterize the electron beam diameter and shape. The system consists of a kapton target insertion mechanism and a framing camera. It has a fast gated imaging tube (500 ps) and CCD subsystem to capture and send the image to the control room. The beam diameter data provides insight on mechanisms that effect the x-ray spot size. These colorful beam measurements will be compared with our other diagnostics to form a more complete picture of beam behavior. A demonstration will be described where the image data was used to design a collimator to improve x-ray beam performance.

    2016-01-01

    Eosinophilic ascites is a rare feature of eosinophilic gastroenteritis. We would like to highlight this increasingly recognised diagnosis in a case of unexplained ascites. We present a challenging case of a woman aged 25 years who presented with nausea, vomiting, diarrhoea, generalised abdominal pain and swelling 8-week following delivery of her first baby. Her symptoms were primarily aggravated by eating, and she had also noticed postprandial itching and self-limiting generalised rash. She had a strong history of atopy. Physical examination revealed abdominal tenderness and distension with shifting dullness. Urticarial skin rash was noted on the face, neck, chest and abdomen. Routine biochemistry was normal apart from peripheral eosinophilia. Imaging confirmed moderate ascites. Diagnostic paracentesis showed exudative ascites with numerous eosinophils. Histology of the upper and lower gastrointestinal tract showed infiltration of the oesophageogastroduodenal and rectosigmoid mucosa with eosinophils. The patient significantly improved following a course of steroids and six-food elimination diet. PMID:27600059

  18. Diagnostic imaging in focal epilepsy

    International Nuclear Information System (INIS)

    Focal epilepsies account for 60% of all seizure disorders worldwide. In this review the classic and new classification system of epileptic seizures and syndromes as well as genetic forms are discussed. Magnetic resonance (MR) is the technique of choice for diagnostic imaging in focal epilepsy because of its sensitivity and high tissue contrast. The review is focused on the lack of consensus of imaging protocols and reported findings in refractory epilepsy. The most frequently encountered MRI findings in epilepsy are reported and their imaging characteristics are depicted. Diagnosis of hippocampal sclerosis and malformations of cortical development as two major causes of refractory focal epilepsy is described in details. Some promising new techniques as positron emission tomography computed tomography (PET/CT) and MR and PET/CT fusion are briefly discussed. Also the relevance of adequate imaging in focal epilepsy, some practical points in imaging interpretation and differential diagnosis are highlighted. (author)

    The CIRFEL system has been operating with electron energies in the range of 11 to 12 MeV and RF pulse length of 3 to 4 {mu}secs. The electrons produced by a Magnesium photocathode illuminated by a 261nm mode locked laser are accelerated in the RF gun, and further boosted in energy by a booster section downstream of the RIF gun. The electrons are energy selected in the bending section before insertion into a permanent magnet wiggler. We describe several recent diagnostic measurements carried out on the CIRFEL system: emittance measurements in two different sections of the beam line, energy and energy spread measurements, and jitter characteristics of the photo cathode drive laser as well as the electron beam energy.

    2014-01-01

    Full Text Available Interstitial lung disease (ILD is a final common pathway of a broad heterogeneous group of parenchymal lung disorders. It is characterized by progressive fibrosis of the lung leading to restriction and diminished oxygen transfer. Clinically, the presenting symptoms of ILD are non-specific (cough and progressive dyspnea on exertion and are often attributed to other diseases, thus delaying diagnosis and timely therapy. Clues from the medical history along with the clinical context and radiologic findings provide the initial basis for prioritizing diagnostic possibilities for a patient with ILD. An accurate prognosis and optimal treatment strategy for patients with ILDs can only be after an accurate diagnosis. This review will assist pulmonary physicians and medicine specialist in recognition of ILD. Extensive literature search has been made through PubMed and also Book References has been used for writing this review.

  1. Diagnostic imaging in child abuse

    International Nuclear Information System (INIS)

    Diagnostic imaging in child abuse plays an important role and includes the depiction of skeletal injuries, soft tissue lesions, visceral injuries in ''battered child syndrome'' and brain injuries in ''shaken baby syndrome''. The use of appropriate imaging modalities allows specific fractures to be detected, skeletal lesions to be dated and the underlying mechanism of the lesion to be described. The imaging results must be taken into account when assessing the clinical history, clinical findings and differential diagnoses. Computed tomography (CT) and magnetic resonance imaging (MRI) examinations must be performed in order to detect lesions of the central nervous system (CNS) immediately. CT is necessary in the initial diagnosis to delineate oedema and haemorrhages. Early detection of brain injuries in children with severe neurological symptoms can prevent serious late sequelae. MRI is performed in follow-up investigations and is used to describe residual lesions, including parenchymal findings. (orig.)

  2. Brucellosis: Epizootiologic and diagnostic challenge

    Directory of Open Access Journals (Sweden)

    Radojičić Sonja

    2005-01-01

    Full Text Available Although it has been known as a separate etiological entity for almost 150 years, brucellosis is, on a global scale, one of the most frequent diseases that is transferred from animals to humans. It is present as an endemic disease in almost all countries of the Mediterranean Sea, which indicates that a large number of aspects in connection with the control and epizootiology of this disease still remain unexplained. Three of the six types of brucella have been officially confirmed in our country as well. They are Brucella melitensis biotip 3, Brucella suis biotip 2 and Brucella canis. Brucellosis is endemically present in Kosovo and Metohija province and in southern Serbia proper; over the past few years, the spread of brucellosis in sheep and goats as primary hosts for B. melitensis to new territories, mostly in Vojvodina province, has shown that risk analysis is one of the main factors in selecting and implementing control programmes. A correctly selected set of diagnostic tests yields reliable data in most cases, but interpretations of results are prone to result in subjective assessments as well. A special problem in the serological diagnosis of brucellosis is the cross reactivity of brucellas and some other bacteria, often a weak immunological response of the animal, or that the type of brucella that causes the infection determines the sensitivity and specificity of the applied tests, most often screenings tests. Due to the big economic losses resulting from disease control and eradication, and the serious risk to human health, brucellosis still poses an epizootiological, and, in particular, a diagnostic challenge.

  3. Objective pain diagnostics: clinical neurophysiology.

    Science.gov (United States)

    Garcia-Larrea, L

    2012-06-01

    Neurophysiological techniques help in diagnosis, prognosis and treatment of chronic pain, and are particularly useful to determine its neuropathic origin. According to current standards, the diagnosis of definite neuropathic pain (NP) needs objective confirmation of a lesion or disease of somatosensory systems, which can be provided by neurophysiological testing. Lesions causing NP mostly concern the pain-temperature pathways, and therefore neurophysiological procedures allowing the specific testing of these pathways (i.e., A-delta and C-fibres, spino-thalamo-cortical tracts) are essential for objective diagnosis. Different techniques to stimulate selectively pain-temperature pathways are discussed. Of these, laser-evoked potentials (LEPs) appear as the easiest and most reliable neurophysiological method of assessing nociceptive function, and their coupling with autonomic responses (e.g., galvanic skin response) and psychophysics (quantitative sensory testing - QST) can still enhance their diagnostic yield. Neurophysiological techniques not exploring specifically nociception, such as standard nerve conduction velocities (NCV) and SEPs to non-noxious stimulation, should be associated to the exploration of nociceptive systems, not only because both may be simultaneously affected to different degrees, but also because some specific painful symptoms, such as paroxysmal discharges, may depend on specific alteration of highly myelinated A-beta fibres. The choice of techniques is determined after anamnesis and clinical exam, and tries to answer a number of questions: (a) is the pain-related to injury of somatosensory pathways?; (b) to what extent are different subsystems affected?; (c) are mechanisms and lesion site in accordance with imaging data?; (d) are results of use for diagnostic or therapeutic follow-up? Neuropathic pain (NP) affects more than 15 million people in Western countries, and its belated diagnosis leads to insufficient or delayed therapy. The use of

  4. Personality Assessment in the Diagnostic Manuals: On Mindfulness, Multiple Methods, and Test Score Discontinuities.

    Science.gov (United States)

    Bornstein, Robert F

    2015-01-01

    Recent controversies have illuminated the strengths and limitations of different frameworks for conceptualizing personality pathology (e.g., trait perspectives, categorical models), and stimulated debate regarding how best to diagnose personality disorders (PDs) in the Diagnostic and Statistical Manual of Mental Disorders (5th ed.), and in other diagnostic systems (i.e., the International Classification of Diseases, the Psychodynamic Diagnostic Manual). In this article I argue that regardless of how PDs are conceptualized and which diagnostic system is employed, multimethod assessment must play a central role in PD diagnosis. By complementing self-reports with evidence from other domains (e.g., performance-based tests), a broader range of psychological processes are engaged in the patient, and the impact of self-perception and self-presentation biases can be better understood. By providing the assessor with evidence drawn from multiple modalities, some of which provide converging patterns and some of which yield divergent results, a multimethod assessment compels the assessor to engage this evidence more deeply. The mindful processing that ensues can help minimize the deleterious impact of naturally occurring information processing bias and distortion on the part of the clinician (e.g., heuristics, attribution errors), bringing greater clarity to the synthesis and integration of assessment data.

  5. Diagnostic randomized controlled trials: the final frontier.

    Clinicians, patients, governments, third-party payers, and the public take for granted that diagnostic tests are accurate, safe and effective. However, we may be seriously misled if we are relying on robust study design to ensure accurate, safe, and effective diagnostic tests. Properly conducted, randomized controlled trials are the gold standard for assessing the effectiveness and safety of interventions, yet are rarely conducted in the assessment of diagnostic tests. Instead, diagnostic cohort studies are commonly performed to assess the characteristics of a diagnostic test including sensitivity and specificity. While diagnostic cohort studies can inform us about the relative accuracy of an experimental diagnostic intervention compared to a reference standard, they do not inform us about whether the differences in accuracy are clinically important, or the degree of clinical importance (in other words, the impact on patient outcomes). In this commentary we provide the advantages of the diagnostic randomized controlled trial and suggest a greater awareness and uptake in their conduct. Doing so will better ensure that patients are offered diagnostic procedures that will make a clinical difference.

    Mild inherited bleeding disorders are relatively common in the general population. Despite recent advances in diagnostic approaches, mild inherited bleeding disorders still pose a significant diagnostic challenge. Hemorrhagic diathesis can be caused by disorders in primary hemostasis (von Willebrand disease, inherited platelet function disorders), secondary hemostasis (hemophilia A and B, other (rare) coagulant factor deficiencies) and fibrinolysis, and in connective tissue or vascular formation. This review summarizes the currently available diagnostic methods for mild bleeding disorders and their pitfalls, from structured patient history to highly specialized laboratory diagnosis. A comprehensive framework for a diagnostic approach to mild inherited bleeding disorders is proposed. PMID:27208505

    Advanced and specialized radiological diagnostics are essential in the case of clinical suspicion of pediatric injuries to the head, thorax, abdomen, and extremities when there is no case history or when ''battered child syndrome'' is assumed on the basis of inadequate trauma. In particular, the aim of this sophisticated diagnostic procedure is the detection of lesions of the central nervous system (CNS) in order to initiate prompt medical treatment. If diagnostic imaging shows typical findings of child abuse, accurate documented evidence of the diagnostic results is required to prevent further endangerment of the child's welfare. (orig.)

  13. Possible room temperature superconductivity in conductors obtained by bringing alkanes into contact with a graphite surface

    Directory of Open Access Journals (Sweden)

    Yasushi Kawashima

    2013-05-01

    Full Text Available Electrical resistances of conductors obtained by bringing alkanes into contact with a graphite surface have been investigated at room temperatures. Ring current in a ring-shaped container into which n-octane-soaked thin graphite flakes were compressed did not decay for 50 days at room temperature. After two HOPG plates were immersed into n-heptane and n-octane at room temperature, changes in resistances of the two samples were measured by four terminal technique. The measurement showed that the resistances of these samples decrease to less than the smallest resistance that can be measured with a high resolution digital voltmeter (0.1μV. The observation of persistent currents in the ring-shaped container suggests that the HOPG plates immersed in n-heptane and n-octane really entered zero-resistance state at room temperature. These results suggest that room temperature superconductor may be obtained by bringing alkanes into contact with a graphite surface.

  14. Where has the public gone and will communications technology bring them back?

    International Nuclear Information System (INIS)

    This paper addresses the decreasing number of persons interested and participating in the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) or open-quotes Superfundclose quotes process. It also looks at communications technology to bring people back into participation in the Superfund process. The material studied and the technologies evaluated involve the Environmental Restoration Program at the Idaho National Engineering and Environmental Laboratory. The conclusions are probably valid for most DOE Superfund activities. Where has the public gone? The public has taken an interest in issues that they perceive have greater impact on their quality of life and that have an adverse impact on the environment, such as the shipment and storage of spent nuclear fuel. Will communications technology bring them back? Technology can do many things: it can reduce cost; it can allow quicker access to and from the public; it can offer more information; and it can increase interest because of its novelty for short periods of time, but it will not, in and of its own, create public involvement

    2011-10-01

    Urologists frequently encounter problems in making a clinical diagnosis whose resolution requires the use of diagnostic tests. With an ever increasing choice of investigations being available, the urologist often has to decide which diagnostic test(s) will best resolve the patient's diagnostic problem. In this article, we aim to help the urologist understand how to critically appraise studies on diagnostic tests and make a rational choice. This article presents the guiding principles in scientifically assessing studies on diagnostic tests by proposing a clinical scenario. The authors describe a standardized protocol to assess the validity of the test and its relevance to the clinical problem that can help the urologist in decision making. The three important issues to be considered when evaluating the validity of the study are to identify how the study population was chosen, how the test was performed and whether there is a comparison to the gold standard test so as to confirm or refute the diagnosis. Then, the urologist would need to know the probability of the test in providing the correct diagnosis in an individual patient in order to decide about its utility in solving the diagnostic dilemma. By performing the steps described in this article, the urologist would be able to critically appraise diagnostic studies and draw meaningful conclusions about the investigations in terms of validity, results and its applicability to the patient's problem. This would provide a scientific basis for using diagnostic tests for improving patient care.

    2004-06-15

    The scale-up of deposition in next-step devices such as ITER will pose new diagnostic challenges. Codeposition of hydrogen with carbon needs to be characterized and understood in the initial hydrogen phase in order to mitigate tritium retention and qualify carbon plasma facing components for DT operations. Plasma facing diagnostic mirrors will experience deposition that is expected to rapidly degrade their reflectivity, posing a new challenge to diagnostic design. Some eroded particles will collect as dust on interior surfaces and the quantity of dust will be strictly regulated for safety reasons - however diagnostics of in-vessel dust are lacking. We report results from two diagnostics that relate to these issues. Measurements of deposition on NSTX with 4 Hz time resolution have been made using a quartz microbalance in a configuration that mimics that of a typical diagnostic mirror. Often deposition was observed immediately following the discharge suggesting that diagnostic shutters should be closed as soon as possible after the time period of interest. Material loss was observed following a few discharges. A novel diagnostic to detect surface particles on remote surfaces was commissioned on NSTX.

    Keeping track of sequences onboard a spacecraft is challenging. When reviewing Event Verification Records (EVRs) of sequence executions on the Mars Exploration Rover (MER), operators often found themselves wondering which version of a named sequence the EVR corresponded to. The lack of this information drastically impacts the operators diagnostic capabilities as well as their situational awareness with respect to the commands the spacecraft has executed, since the EVRs do not provide argument values or explanatory comments. Having this information immediately available can be instrumental in diagnosing critical events and can significantly enhance the overall safety of the spacecraft. This software provides auditing capability that can eliminate that uncertainty while diagnosing critical conditions. Furthermore, the Restful interface provides a simple way for sequencing tools to automatically retrieve binary compiled sequence SCMFs (Space Command Message Files) on demand. It also enables developers to change the underlying database, while maintaining the same interface to the existing applications. The logging capabilities are also beneficial to operators when they are trying to recall how they solved a similar problem many days ago: this software enables automatic recovery of SCMF and RML (Robot Markup Language) sequence files directly from the command EVRs, eliminating the need for people to find and validate the corresponding sequences. To address the lack of auditing capability for sequences onboard a spacecraft during earlier missions, extensive logging support was added on the Mars Science Laboratory (MSL) sequencing server. This server is responsible for generating all MSL binary SCMFs from RML input sequences. The sequencing server logs every SCMF it generates into a MySQL database, as well as the high-level RML file and dictionary name inputs used to create the SCMF. The SCMF is then indexed by a hash value that is automatically included in all command

  13. Diagnostics of solar flare reconnection

    2004-01-01

    Full Text Available We present new diagnostics of the solar flare reconnection, mainly based on the plasma radio emission. We propose that the high-frequency (600-2000 MHz slowly drifting pulsating structures map the flare magnetic field reconnection. These structures correspond to the radio emission from plasmoids which are formed in the extended current sheet due to tearing and coalescence processes. An increase of the frequency drift of the drifting structures is interpreted as an increase of the reconnection rate. Using this model, time scales of slowly drifting pulsating structure observed during the 12 April 2001 flare by the Trieste radiopolarimeter with high time resolution (1 ms are interpreted as a radio manifestation of electron beams accelerated in the multi-scale reconnection process. For short periods Fourier spectra of the observed structure have a power-law form with power-law indices in the 1.3-1.6 range. For comparison the 2-D MHD numerical modeling of the multi-scale reconnection is made and it is shown that Fourier spectrum of the reconnection dissipation power has also a power-law form, but with power-law index 2. Furthermore, we compute a time evolution of plasma parameters (density, magnetic field etc in the 2-D MHD model of the reconnection. Then assuming a plasma radio emission from locations, where the 'double-resonance' instability generates the upper-hybrid waves due to unstable distribution function of suprathermal electrons, we model radio spectra. Effects of the MHD turbulence are included. The resulting spectra are compared with those observed. It is found, that depending on model parameters the lace bursts and the decimetric spikes can be reproduced. Thus, it is shown that the model can be used for diagnostics of the flare reconnection process. We also point out possible radio signatures of reconnection outflow termination shocks. They are detected as type II-like herringbone structures in the 200-700 MHz frequency range. Finally

    Although the American Apollo and Soviet Luna missions concentrated on mare basalt samples, major questions remain about lunar volcanism. Lunar field work will be indispensable for resolving the scientific questions about ages, compositions, and eruption processes of lunar volcanism. From a utilitarian standpoint, a better knowledge of lunar volcanism will also yield profitable returns in lunar base construction (e.g., exploitation of rille or lava-tube structures) and in access to materials such as volatile elements, pure glass, or ilmenite for lunar industry

    Autoimmune chronic pancreatitis (AIP) is increasingly being recognized worldwidely, as knowledge of this entity builds up. Above all, AIP is a very attractive disease to clinicians in terms of its dramatic response to the oral steroid therapy in contrast to ordinary chronic pancreatitis. Although many characteristic findings of AIP have been described, definite diagnostic criteria have not been fully established. In the year 2002, the Japan Pancreas Society published the diagnostic criteria of AIP and many clinicians around the world use these criteria for the diagnosis of AIP. The diagnostic criteria proposed by the Japan Pancreas Society, however, are not completely satisfactory and some groups use their own criteria in reporting AIP. This review discusses several potential limitations of current diagnostic criteria for this increasingly recognized condition. The manuscript is organized to emphasize the need for convening a consensus to develop improved diagnostic criteria.

  19. User interface graphically improves generator AL diagnostics

    International Nuclear Information System (INIS)

    In April of 1990, the recently developed Diagnostic Graphical User Interface (DGUI) was installed at a large nuclear power plant in the midwestern United States. Since 1988, the power plant has been using the Generator Artificial Intelligence Diagnostics (GenAID) System, which provides online diagnostic capability for the generator and generator auxiliaries through a plant data center (PDC) and communication link to the diagnostic operations center (DOC) in Orlando, Florida. The enhanced system provides the power plant control room operator with a comprehensive tool to understand and better utilize the information provided by the existing knowledge bases. This paper represents a significant improvement over existing technology by providing the power plant control room operator with the capability of interacting directly with the diagnostic system

    This book of proceedings collects the papers presented at the Workshop on Diagnostics for ITER, held at Villa Monastero, Varenna (Italy), from August 28 to September 1, 1995. The Workshop was organised by the International School of Plasma Physics "Piero Caldirola. " Established in 1971, the ISPP has organised over fifty advanced courses and workshops on topics mainly related to plasma physics. In particular, courses and workshops on plasma diagnostics (previously held in 1975, 1978, 1982, 1986, and 1991) can be considered milestones in the history of this institution. Looking back at the proceedings of the previous meetings in Varenna, one can appreciate the rapid progress in the field of plasma diagnostics over the past 20 years. The 1995 workshop was co-organised by the Istituto di Fisica del Plasma of the National Research Council (CNR).

    Molecular profiling, which is the application of molecular diagnostics technology to tissue and blood -specimens, is an integral element in the new era of molecular medicine and individualized therapy. Molecular diagnostics is a fertile ground for small business development because it can generate products that meet immediate demands in the health-care sector: (a) Detection of disease risk, or early-stage disease, with a higher specificity and sensitivity compared to previous testing methods, and (b) "Companion diagnostics" for stratifying patients to receive a treatment choice optimized to their individual disease. This chapter reviews the promise and challenges of business development in this field. Guidelines are provided for the creation of a business model and the generation of a marketing plan around a candidate molecular diagnostic product. Steps to commercialization are outlined using existing molecular diagnostics companies as learning examples.

    Working within frameworks drawn from the writings of Immanuel Kant, Alfred Schutz, and Kenneth Burke, this article examines the role that diagnostic categories play in autobiographical accounts of illness, with a special focus on chronic disease. Four lay diagnostic categories, each with different connections to formal medical diagnostic categories, serve as typifications to make sense of the way the lifeworld changes over the course of chronic illness. These diagnostic categories are used in conjunction with another set of typifications: lay epidemiologies, lay etiologies, lay prognostics, and lay therapeutics. Together these serve to construct and reconstruct the self at the center of the lifeworld. Embedded within the lay diagnostic categories are narratives of progression, regression, or stability, forms of typification derived from literary and storytelling genres. These narratives are developed by the self in autobiographical accounts of illness. PMID:26657684

    Clinical use of endoscopic ultrasound (EUS) diagnostics of 550 patients with diseases of hepatobiliary and pancreas was analyzed. The procedure of the examination was thoroughly described. Ultrasound semiotics of the pancreas, papilla Vateri and bile ducts' lesions was defined. Accuracy of EUS in the diagnostics of solid pancreas tumors was 81,6%. Accuracy of the method in the diagnostics of the vessel invasion was 81,6%. EUS was considered to be leading in the diagnostics of papilla Vateri and duodenal tumors, its accuracy was up to 97,2%, which is much higher then other radiological and endoscopic methods. EUS was highly effective in diagnostics of choledocholithiasis and comprised 90,2%. The introduction of thin-needle biopsy, Doppler mapping and elastography in the EUS protocol permitted further increase of the accuracy and value of the method for the surgical practice.

    The National Ignition Facility (NIF) requires diagnostics to analyze high-energy density physics experiments. As a core NIF early light diagnostic, this system measures shock velocities, shock breakout times, and shock emission of targets with sizes from 1 to 5 mm. A 659.5 nm VISAR probe laser illuminates the target. An 8-inch-diameter fused silica triplet lens collects light at f/3 inside the 33-foot-diameter vacuum chamber. The optical relay sends the image out an equatorial port, through a 2-inch-thick vacuum window, and into two VISAR (Velocity Interferometer System for Any Reflector) interferometers. Both streak cameras and CCD cameras record the images. Total track is 75 feet. The front end of the optical relay can be temporarily removed from the equatorial port, allowing for other experimenters to use that port. The first triplet can be no closer than 500 mm from the target chamber center and is protected from debris by a blast window that is replaced after every event. Along with special coatings on the mirrors, cutoff filters reject the NIF drive laser wavelengths and pass a band of wavelengths for VISAR, for passive shock breakout light, or for thermal imaging light (bypassing the interferometers). Finite Element Analysis was performed on all mounting structures. All optical lenses are on kinematic mounts, so that the pointing accuracy of the optical axis can be checked. A two-color laser alignment scheme is discussed.

  6. Morton neuroma: MRI diagnostic value

    International Nuclear Information System (INIS)

    Objective: To evaluate the diagnostic value of MRI in Morton's Neuroma (MN). Material and methods: 23 patients with clinical diagnosis of MN were examined under two different protocols, with a 1.5 T Magnet. 1) T1, FSET2, FIR, T1 with contrast enhancement and fat suppression; 2) T1, FSET2, FIR without contrast enhancement (i.v. Gadolinium). Results: In the first group MN was found in 7 patients. In the second group 14 patients were studied, 7 with positive MR for neuroma, and 9 with negative MR. 6 were true-negative and 3 were false-negative. The Fisher Test between both groups was p < 0.05. Conclusion: MRI is effective for the diagnosis of Morton neuroma. The use of gadolinium and fat suppression significantly improved the detection of Morton neuroma, allowing better measurements of the lesion. These findings do not correlate with previous papers that do not encourage the use of i.v. Gadolinium. (author)

  7. Microbiological diagnostics of fungal infections

    2013-07-01

    Full Text Available Laboratory tests for the detection of fungal infections are easy to perform. The main obstacle to a correct diagnosis is the correlation between the laboratory findings and the clinical diagnosis. Among pediatric patients, the most common fungal pathogen is Candida. The detection of fungal colonization may be performed through the use of chromogenic culture media, which allows also the identification of Candida subspecies, from which pathogenicity depends. In neonatology, thistest often drives the decision to begin a empiric therapy; in this regard, a close cooperation between microbiologists and clinicians is highly recommended. Blood culture, if positive, is a strong confirmation of fungal infection; however, its low sensitivity results in a high percentage of false negatives, thus decreasing its reliability. Molecular diagnostics is still under evaluation, whereas the detection of some fungal antigens, such as β-D-glucan, galactomannan, mannoprotein, and cryptococcal antigen in the serum is used for adults, but still under evaluations for pediatric patients.http://dx.doi.org/10.7175/rhc.v4i1S.862

    Tibial hyperostosis may be encountered in musculoskeletal imaging, incidentally or during the investigation of a leg pain. Hyperostosis involves the exuberant production of osseous tissue and results in cortical, periosteal and/or endosteal thickening of the bone. As a long bone with thick cortices, the tibia has a significant probability of being affected by ubiquitous bone diseases. As a tubular long bone, the tibia is likely to be involved in extensive infectious conditions such as osteomyelitis. As a bone of the lower limb, the tibia undergoes high stresses and may be affected by decrease in bone strength or repetitive submaximal stress. The tibia is also particularly involved in some bone sclerosing dysplasias and Paget's disease. In this work, we aim at highlighting the main conditions leading to tibial hyperostosis and try to provide key elements to narrow down the several diagnostic possibilities. Osteoid osteomas, fatigue or insufficiency fractures, infectious conditions, vascular lesions, sclerosing bone dysplasias and Paget's disease represent the main challenging diagnoses to discuss.

    Vasculitis is characterized by an inflammatory reaction of vessel walls with damage to the dependent tissues. Forms of vasculitis which frequently have skin changes include leukocytoclastic angiitis (LcV), Henoch-Schönlein purpura (HSP), cutaneous polyarteriitis nodosum (cPAN), erythema elevatum et diutinum (EED) and urticarial vasculitis (UV). In other forms of vasculitis, systemic manifestations predominate but there are a variety of skin changes. Kawasaki disease (MK), cryoglobulinemic vasculitis (kV), Wegener granulomatosis (WG), Churg-Strauss syndrome (CSS) and microscopic polyangitis (MPA) belong to this group. The causes of vasculitis are heterogeneous. Triggers include infections, drugs, collagen vascular diseases, autoimmune diseases and lymphoproliferative disorders. Idiopathic vasculitis, particularly LcV and EED, occur only once and have a self-limited course. The diagnostic work up depends on the clinical picture and includes inflammatory markers, circulating immune complexes, different types of cryoglobulins and anti-neutrophilic cytoplasmic antibodies, collagen vascular disease specific autoantibodies and additional hematological studies. Vasculitis can manifest in many organs and requires a thorough work up specifically in cases where WG, MPA, CSS and PAN are under consideration. PMID:18415062

Patient history and assessment of nasal symptoms are essential components of diagnosis, providing an initial evaluation that may be adequate to rule out serious conditions. However, current congestion medications are not always fully effective. Thus, if symptoms do not respond adequately to therapy, or symptoms suggestive of more serious conditions are present, specialized assessments may be needed. Various techniques are available for diagnosing patients, including those used chiefly by primary care clinicians and those requiring the expertise of otolaryngologists, allergists, and other specialists. Endoscopy remains a mainstay for evaluating nasal blockage and its causes, while modalities such as peak nasal inspiratory flow and acoustic rhinometry are evolving to provide easy-to-use, noninvasive procedures that are sensitive enough to measure small but clinically important abnormalities and therapeutic changes. Several imaging modalities are available to the specialist for severe or unusual cases, as are specialized diagnostic procedures that measure adjunctive features of congestion, such as impaired mucociliary function.Keywords: allergic rhinitis, congestion, diagnosis, obstruction, rhinosinusitis

    2016-01-01

    Communication is an essential element of good medical practice also in pathology. In contrast to technical or diagnostic skills, communication skills are not easy to define, teach, or assess. Rules almost do not exist. In this paper, which has a rather personal character and cannot be taken as a set of guidelines, important aspects of communication in pathology are explored. This includes what should be communicated to the pathologist on the pathology request form, communication between pathologists during internal (interpathologist) consultation, communication around frozen section diagnoses, modalities of communication of a final diagnosis, with whom and how critical and unexpected findings should be communicated, (in-)adequate routes of communication for pathology diagnoses, who will (or might) receive pathology reports, and what should be communicated and how in case of an error or a technical problem. An earlier more formal description of what the responsibilities are of a pathologist as communicator and as collaborator in a medical team is added in separate tables. The intention of the paper is to stimulate reflection and discussion rather than to formulate strict rules.

    Eddy, T.L.; Grandy, J.D.

    1990-01-01

    This paper describes possible techniques by which the state of plasma thruster operation for space propulsion can be determined from a minimum set of experimental data in the laboratory. The kinetic properties of the nonequilibrium plasma plume usually can not be directly related to the observed radiation; hence, appropriate nonequilibrium diagnostic techniques must be employed. A newly developed multithermal, multichemical equilibrium method is discussed that uses measured line emission intensities and N equations to solve for N unknowns. The effect of arbitrarily changing the number of selected N unknowns and how one determines the optimum (minimum) number to be used for a given composition is also presented. The chemical nonequilibrium aspects and the application to molecular species have not yet been published. The important conclusions are that (1) complete thermodynamic systems in nonequilibrium can be described by relatively few variables if appropriate choices and filtering methods are used, (2) a few radiation measurements can yield valid kinetic properties, and (3) the major question in the relations to be used is in the form of the law of mass action. The results are substantiated in the laboratory by additional alternative methods of measurement of some of the kinetic properties. 13 refs., 1 fig.

    Full Text Available The low productivity of buffalo herds and condemnation of carcasses in slaughterhouses due to tuberculosis lesions have resulted in increasing economic losses because these animals cannot be treated and must be destroyed by sanitary slaughter. Tuberculosis is a widely distributed zoonosis that affects the beef supply chain of the Brazilian agribusiness economically and socially. Like cattle, buffaloes are sensitive to Mycobacterium bovis, which is the main causative agent of zoonotic tuberculosis. Tuberculosis in buffaloes has been reported in several countries, including Brazil. In order to control and eradicate this disease among cattle and buffaloes in Brazil, the Ministry of Agriculture, Livestock, and Supply created the National Program for the Control and Eradication of Brucellosis and Tuberculosis with the main objective of finding a significant number of disease-free herds throughout the national territory using reliable methods. This review summarizes the main data on the history of occurrence of M. bovis in Brazilian herds and the diagnostic methods for the disease in buffaloes. Little information is available on buffalo tuberculosis. Due to the increasing population of buffaloes and their economic importance, more studies investigating the occurrence and identification of tuberculosis in this species are clearly needed.

    Salivary diagnostics is an emerging field that has progressed through several important developments in the past decade, including the publication of the human salivary proteome and the infusion of federal funds to integrate nanotechnologies and microfluidic engineering concepts into developing compact point-of-care devices for rapid analysis of this secretion. In this article, we discuss some of these developments and their relevance to the prognosis, diagnosis and management of periodontitis, as an oral target, and cardiovascular disease, as a systemic example for the potential of these biodiagnostics. Our findings suggest that several biomarkers are associated with distinct biological stages of these diseases and demonstrate promise as practical biomarkers in identifying and managing periodontal disease, and acute myocardial infarction. The majority of these studies have progressed through biomarker discovery, with the identified molecules requiring more robust clinical studies to enable substantive validation for disease diagnosis. It is predicted that with continued advances in this field the use of a combination of biomarkers in multiplex panels is likely to yield accurate screening tools for these diagnoses in the near future.

    Salivary diagnostics is an emerging field that has progressed through several important developments in the past decade, including the publication of the human salivary proteome and the infusion of federal funds to integrate nanotechnologies and microfluidic engineering concepts into developing compact point-of-care devices for rapid analysis of this secretion. In this article, we discuss some of these developments and their relevance to the prognosis, diagnosis and management of periodontitis, as an oral target, and cardiovascular disease, as a systemic example for the potential of these biodiagnostics. Our findings suggest that several biomarkers are associated with distinct biological stages of these diseases and demonstrate promise as practical biomarkers in identifying and managing periodontal disease, and acute myocardial infarction. The majority of these studies have progressed through biomarker discovery, with the identified molecules requiring more robust clinical studies to enable substantive validation for disease diagnosis.

    2015-10-01

    The notion of bringing technology into the classroom has been the subject of many recent presentations at conferences and papers in physics teaching journals. The use of devices such as laptops, smartphones, tablets, and clickers is rising in today's classrooms and laboratories. PhET simulations have been available online for over a decade. A column in The Physics Teacher, called "iPhysicsLabs," was begun in February of 2012 and describes experiments to be carried out with smartphones and tablets. Students have become familiar with the operation and application of such technology. But are they aware of the underlying physics necessary to make the devices and the online simulations work? Much of the physics is hidden at the microscopic level in tiny circuit chips or in the workings of a distant server.

    2008-01-01

    The human immune system protects the human body against various pathogens like e.g. biological viruses and bacteria. Artificial immune systems reuse the architecture, organization, and workflows of the human immune system for various problems in computer science. In the network security, the artificial immune system is used to secure a network and its nodes against intrusions like viruses, worms, and trojans. However, these approaches are far away from production where they are academic proof-of-concept implementations or use only a small part to protect against a certain intrusion. This article discusses the required steps to bring artificial immune systems into production in the network security domain. It furthermore figures out the challenges and provides the description and results of the prototype of an artificial immune system, which is SANA called.

    Dasch, Cameron J.

    2008-02-01

    The automotive industry is in the midst of a time of tremendous change. There is an almost perfect storm of changing governmental and market requirements seeking much higher fuel economy, low or no carbon dioxide emissions, and much higher crash and safety performance. Moreover, this occurs in a globe-spanning market that has more low-cost manufacturers than ever before. This confluence of factors leads to new vehicles with many new types of powertrains having unprecedented power densities and highly-engineered body structures with many new materials and joining methods. These are being turned out with shorter lead times, higher quality requirements, and continuous cost pressures. This talk will review the role in NDE in bringing new materials and processes to market, some of the applications in production, and to highlight some of the current NDE needs driven by these forces on the automotive industry.

    2016-01-01

    Smartphones continue to provide huge potential for psychological science and the advent of novel research frameworks brings new opportunities for researchers who have previously struggled to develop smartphone applications. However, despite this renewed promise, smartphones have failed to become a standard item within psychological research. Here we consider the key issues that continue to limit smartphone adoption within psychological science and how these barriers might be diminishing in light of ResearchKit and other recent methodological developments. We conclude that while these programming frameworks are certainly a step in the right direction it remains challenging to create usable research-orientated applications with current frameworks. Smartphones may only become an asset for psychology and social science as a whole when development software that is both easy to use and secure becomes freely available. PMID:27602010

  2. Descendit ad [in] inferna: ‘A matter of no small moment in bringing about redemption’

    2009-09-01

    Full Text Available This article endorses Calvin’s conviction that the ‘descendit ad inferna’ of the Apostles’ Creed is part of the ‘summary of doctrine‘ and a matter of ‘no small moment in bringing about redemption‘ (Calvin 1960:Inst. II, xvi, 8. The reason for this role, however, is not Calvin’s metaphorical interpretation of the clause. Instead, the author tries to argue that a scientific theological approach will maintain the clause because of its transcendence of finitude and the proclamation of Christ’s victory. The whole of creation is delivered from sin. Proper hermeneutics will take the original socio–historical environment into account and make one suspicious about certain ecclesiastical biases. Spatial terms in the Creed should therefore not be demythologised, but rather be transformed in accordance with the insights of the contemporary physics of time and space.

    1999-12-01

    The process of bringing new food products from innovation to implementation requires a high level of interaction between researchers, marketers, and consumers. Researchers from industry and academia have the task of developing products that are not only efficacious, but also have a high probability of consumer acceptance. For most foods, industry must provide the most leadership in finding new product concepts, determining which products will have the widest markets, and in funding research and development. To accomplish these tasks, industry has forged partnerships with academic centers and scientists who excel in research and development, and continues to search for the best ways to communicate with consumers. For some FSMPs, other considerations, such as medical and nutritional needs (e.g., products for inborn errors of metabolism), might change the pattern of industry leadership. The following article explores the ways in which industry can facilitate the development and acceptance of beneficial and marketable food products. PMID:10723641

    Full Text Available The primary purpose of Brigham Young University (BYU is to provide students with a combination of sacred and secular education often described as the "BYU experience". Achieving this purpose is challenged by the rapid growth in Church membership and an enrollment cap of 30,000 students. To address these challenges, BYU sponsors the use of technology to bridge the gap between the increased Church membership and the number of students allowed under the enrollment caps. This institutional case study shows how these challenges have influenced the hybridization of teaching and learning for on campus (resident and off campus (distance students. It also describes how BYU has brought distance education to campus, and is beginning to bring campus-based educational practices to distance education.

    2016-03-01

    Our appreciation of the scholarly ideas and thinking of Bob Williams is illustrated here by a few of the areas in which he inspired us. His journey to bring inorganic chemistry to life began with an early interest in analytical chemistry, rationalising the relative stabilities of metal coordination complexes (The Irving-Williams Series), and elucidating the organometallic redox chemistry of vitamin B12. He (and Vallee) recognised that metal ions are in energised (entatic) states in proteins and enzymes, which themselves are dynamic structures of rods and springs. He played a key role in helping Rosenberg to pave the road toward the clinic for the anticancer drug cisplatin. He believed that evolution is not just dependent on DNA, but also on the metallome. Organisms and the environment are one system: does DNA code directly for all the essential elements of life? PMID:26841789

    The politics of population control and its sometimes coercive methods in developing countries documented during the 1960s, 70s and 80s, gave rise to strong opposition by women's groups, and put into question the safety of contraceptive methods that were being developed and introduced into countries. In 1991, the Special Programme on Human Reproduction at the World Health Organization, a research programme focused on development of new methods and safety assessments of existing fertility regulation methods, started a process of "dialogue" meetings between scientists and women's health advocacy groups which lasted for nearly a decade. This paper describes the process of these meetings and what they achieved in terms of bringing new or different research topics into the agenda, and some of the actions taken as a result.

    Project-based learning, which has gained significant attention within K-12 education, provides rich hands-on experiences for students. Bringing an element of service to the projects allow students to engage in a local or global community, providing an abundance of benefits to the students’ learning. For example, service projects build confidence, increase motivation, and exercise problem-solving and communication skills in addition to developing a deep understanding of content. I will present lessons I have learned through four years of providing service learning opportunities in my classroom. I share ideas for astronomy projects, tips for connecting and listening to a community, and helpful guidelines to hold students accountable in order to ensure a productive and educational project.

    Full Text Available This research sheds a light on an under-researched topic of job satisfaction in Kazakhstan. Young people, who today are pursuing their bachelor degree, but tomorrow will start working, were chosen as a sample. This article should be especially interesting to employers because it reveals which factors – among those that potentially contribute to job satisfaction – will bring the expected effect in Kazakhstan and thus are worthy of investments. The study is based on the survey conducted by the Society for Human Resource Management (SHRM in the years 2005- 2012 among U.S. employees. The results of the study suggest that rating list of factors that mostly contribute to job satisfaction, which was compiled on the basis of the answers provided by the respondents from Kazakhstan, is quite different from the rating lists of factors mostly contributing to job satisfaction of U.S. employees.

    This commentary describes an initiative to bring national and international guest scientists to undergraduate and introductory graduate classrooms via web videoconferencing to facilitate interesting and effective research-informed teaching. Interactions center around both journal articles authored by the guests that are in line with weekly course lecture topics and on learning about the nature of academia in other parts of the world. Some particularly interesting perspectives from guests have come about by connecting with a journal editor-in-chief, a textbook author and with a scientist who shared a recently rejected manuscript and peer reviews. Beyond allowing students a unique behind-the-scenes look into how research questions are asked and answered, this initiative helps overcome the limited nature of a single instructor's research area to better complement the comprehensive scope of university courses.

    The release of the Encyclical by Pope Francis has opened a powerful new venue to bring forth the urgency of climate change to the public. The background work that preceded the encyclical was several years in the making. The Church has its own Science Academy, known as the Pontifical Academy of Sciences, consisting of 80 members from around the world with more than a third Nobel Laureates. The members are chosen for their scientific excellence (like most science academies of the world) and not for their religious affiliations. This academy organized a series of scientific meetings for the last 5 years, culminating in a 2014 workshop entitled: Sustainable Humanity, Sustainable Nature , Our Responsibility, jointly organized with the Pontifical Academy of Social Sciences. This meeting of the world's thought leaders in natural and Social sciences, came to a remarkable set of conclusions: Climate Change has become a moral issue. A fundamental change in our attitude towards natue and towards each other is required to solve the problem. Religious leaders can have a transformational effect by mobilizing public opinion for actions to stabilize climate change and protect the people. Being a council member of the Pontifical Academy and watching from within the powerful moral voice of Pope Francis, I conclude that this partnership with religion is a powerful new venue for those researchers, reticent about publicly voicing their grave concerns to pursue. We are going to bring massive public support for urgent actions only when the impacts of climate change and its origins are taught in every church, every temple, every mosque, every synagogue, and other places of worship.

    International Nuclear Information System (INIS)

    At SMORN 8, a new web-based diagnostic system - web4diagnostics - was presented (Kunze, 2002). During the last two years, this system became the standard diagnostic system infrastructure for internal use in Siemens Power Generation, which integrates a large data archive of measured data and capabilities for data analysis and evaluation. Besides this internal use, today some 15 power plants worldwide use web4diagnostics in their companies communication network. Essential features are: monitoring and diagnostic information are provided in HTML page format; diagnosis can be performed on any suitable machine in the computer network; a 'central diagnostic laboratory' can be configured as a virtual facility using the existing IT infrastructure; analysis results can be accessed from any computer in the information network, only a web browser is required. The system employs well-known standard diagnostic modules and also owns tools such as operational based limit surveillance, automatic report generation and automatic information in case of deviations.

  16. Modelling reflections on ITER CXRS diagnostic

    Cantarini, J. [Max Planck Institute, Greifswald (Germany); Barnsley, R.; Thomas, D. [ITER Organization, Saint Paul les Durance (France)

    2011-07-01

    Modelling reflections on ITER will yield important input data for the design of all IR-Vis-UV diagnostics. The outcome of modelling reflections enables us to describe how parasitic light entering a collection optic will affect the signal-to-noise ratio of the measurement. The deterioration of the signal by stray light could be especially significant for optical diagnostics, such as the Charge exchange Recombination Spectroscopy (CXRS) diagnostic, which suffer from high attenuation of the dedicated diagnostic beam and important background radiation (Bremsstrahlung and first wall light reflection of the diagnostic beam). In order to quantify the deterioration of the CXRS diagnostic signal which is the main measurement tool for the ion temperature profile and helium concentration, an analysis of parasitic light within the ITER vessel has been made. This study is supported by the light modelling software package Light Tools which has adapted solid modelling technology to accommodate the inherent accuracy required to simulate ray paths of light as they traverse through, and within, optical elements and mechanical structures. Therefore as a first study, different specular distribution scenarios of monochromatic visible parasitic light provided by reflections of a simplified model of the ITER first wall have been investigated at the Upper Port 3 and Equatorial Port 3 input of the CXRS diagnostic. The corresponding signal-to-noise ratios have been calculated as well. (authors)

  17. A Framework to Debug Diagnostic Matrices

    Science.gov (United States)

    Kodal, Anuradha; Robinson, Peter; Patterson-Hine, Ann

    2013-01-01

    Diagnostics is an important concept in system health and monitoring of space operations. Many of the existing diagnostic algorithms utilize system knowledge in the form of diagnostic matrix (D-matrix, also popularly known as diagnostic dictionary, fault signature matrix or reachability matrix) gleaned from physical models. But, sometimes, this may not be coherent to obtain high diagnostic performance. In such a case, it is important to modify this D-matrix based on knowledge obtained from other sources such as time-series data stream (simulated or maintenance data) within the context of a framework that includes the diagnostic/inference algorithm. A systematic and sequential update procedure, diagnostic modeling evaluator (DME) is proposed to modify D-matrix and wrapper logic considering least expensive solution first. This iterative procedure includes conditions ranging from modifying 0s and 1s in the matrix, or adding/removing the rows (failure sources) columns (tests). We will experiment this framework on datasets from DX challenge 2009.

  18. Radiological diagnostics of pediatric lungs

    International Nuclear Information System (INIS)

    Pediatric lung diseases are a common clinical problem. Besides the clinical examination and laboratory tests, imaging studies are the mainstay in the diagnostics of pediatric lung diseases. Thorough consideration of radiation protection based on optimized equipment also includes the protection of relatives and medical staff. The high impact of radiation protection in children necessitates a different choice of imaging modalities compared to adults. Ultrasound and magnetic resonance imaging (MRI) as adjunct or complementary imaging methods are of greater value than computed tomography (CT). The suspicion of pneumonia is the most common reason for chest imaging examinations in children. An anteroposterior or posteroanterior view chest X-ray is sufficient in most cases and sometimes in combination with ultrasound. The latter can also be used alone for follow-up examinations if the clinical presentation does not change. Additionally, ultrasound is applied to examine unclear structures seen on chest X-rays, such as the thymus or pulmonary sequestration in adjunct with color-coded duplex sonography. A chest X-ray is also the method of choice to examine the various forms of respiratory distress syndrome, such as wet lung disease or surfactant deficiency syndrome in newborns. Fluoroscopy is used in older children with suspected ingestion and/or aspiration of foreign bodies and CT is mostly used for staging and follow-up of thoracic and pulmonary structures in pediatric oncology. Recent technical advances, e.g. iterative reconstruction, have dramatically reduced the CT dosage. Apart from some indications (e.g. tumors and sequestration) MRI is rarely used in children; however, its potential for functional analyses (e.g. perfusion and ventilation) may increase the application in the near future.

    Full Text Available 1. The most important challenge in diagnosis of celiac disease is not-performing the diagnostic tests in suspected persons. Because of multi-organ damage and multiple manifestations of disease, diagnosis of celiac disease may be delayed. It seems general physicians should be aware about uncommon presentations of disease and indications of celiac tests. 2. The second most important challenge is in patients with suspected disease but negative serologic tests. In these cases evaluating of HLA can be useful. 3. The third challenge is in cases with positive serologic tests but negative histopathological findings. There may be false positive serologic response or consumption of gluten before testing. We recommend introduction of gluten for at least 3 mo and re- endoscopy and if diagnosis is equivocal HLA-typing for DQ8 and DQ2 should be done. 4. The forth challenge is about performing endoscopy. Based on guideline from ESPGHAN if there are typical clinical manifestations of celiac disease, Anti-TTG more than ten times UPN, positive Anti-EMA and HLA DQ2, performing endoscopy may not be necessary, but many physicians don’t agree with this idea. 5. In people who are genetically predisposed to celiac disease antibody levels may be fluctuating thus endoscopy with biopsy should be done in these patients. 6. In children lower than 2years, Anti- TTG and Anti –EMA have low sensitivity. we recommend Anti-TTG and Anti-DGP in these patients. 7. Resolution of symptoms after gluten free diet is not necessarily a feature of celiac disease. This condition may be seen in patients with IBS or non-celiac gluten sensitivity.
