    Despite the prevalence of PowerPoint in professional and educational presentations, surprisingly little is known about how effective such presentations are. All else being equal, are PowerPoint presentations better than purely oral presentations or those that use alternative software tools? To address this question we recreated a real-world business scenario in which individuals presented to a corporate board. Participants (playing the role of the presenter) were randomly assigned to create PowerPoint, Prezi, or oral presentations, and then actually delivered the presentation live to other participants (playing the role of corporate executives). Across two experiments and on a variety of dimensions, participants evaluated PowerPoint presentations comparably to oral presentations, but evaluated Prezi presentations more favorably than both PowerPoint and oral presentations. There was some evidence that participants who viewed different types of presentations came to different conclusions about the business scenario, but no evidence that they remembered or comprehended the scenario differently. We conclude that the observed effects of presentation format are not merely the result of novelty, bias, experimenter-, or software-specific characteristics, but instead reveal a communication preference for using the panning-and-zooming animations that characterize Prezi presentations.

One hundred JSS 1 students (53 male and 47 female categorized into 29 high, 54 medium and 17 low achievers from two secondary schools in Abuja Metropolis formed the sample. The schools were randomly assigned to experimental and control groups. The experimental group was taught some selected concepts from Technical Drawing using PowerPoint Presentation (PPT while Chalkboard method (CB was used for the control group. A validated Technical Drawing Achievement Test (TDAT comprising a 25-item multiple-choice test was employed for data collection. The reliability coefficient of TDAT was .88 using Kuder-Richardson (KR-20. The hypotheses were tested using ANCOVA and Sidak post-hoc analysis. Results revealed that the students taught with PPT performed better than their counterparts taught with CB. Also, high achievers performed better than medium and low achievers respectfully. The PPT was found also to be gender friendly. Based on the findings, it was recommended that the use of PPT should be encouraged in Nigerian schools.

    PowerPoint presentations (PPTs) have become routine in medical colleges because of their flexible and varied presentation capabilities. Research indicates that students prefer PPTs over the chalk-and-talk method, and there is a lot of debate over advantages and disadvantages of PPTs. However, there is no clear evidence that PPTs improve student learning/performance. Furthermore, there are a variety of learning styles with sex differences in classrooms. It is the responsibility of teacher/facilitator and student to be aware of learning style preferences to improve learning. The present study asked the following research question: do PPTs equally affect the learning of students with different learning styles in a mixed sex classroom? After we assessed students' predominant learning style according to the sensory modality that one most prefers to use when learning, a test was conducted before and after a PPT to assess student performance. The results were analyzed using Student's t-test and ANOVA with a Bonferroni post hoc test. A z-test showed no sex differences in preferred learning styles. There was significant increase in posttest performance compared with that of the pretest in all types of learners of both sexes. There was also a nonsignificant relationship among sex, learning style, and performance after the PPT. A PPT is equally effective for students with different learning style preferences and supports mixed sex classrooms. Copyright © 2015 The American Physiological Society.

    2017-01-01

    Full Text Available In medical vocational high schools teachers frequently use PowerPoint presentations. The study presented in this paper has sought to identify, on the one hand, the preferences of students of medical vocational high schools regarding PowerPoint presentations in the instruction of vocational subjects, and on the other, students' dominant learning styles, and also as to establish whether the differences in preferences were based on learning styles. In this cross-sectional study, responses from 170 students of three medical high schools were obtained using the questionnaire designed by Chan and Denner. The data were processed using the methods of descriptive and inferential statistics. The values obtained for Cronbach's alpha indicate that the questionnaire was reliable. In all three schools, PowerPoint presentations are used in the teaching of most vocational subjects. According to the findings, students prefer teaching that uses PowerPoint presentations, finding it more interesting than teaching that involves teachers writing on the board. On the other hand, students' responses indicate that PowerPoint presentations don't lead to greater classroom participation. The findings show that dominant learning styles contribute to differences in student preferences for classes in which teachers use PowerPoint presentations, but also indicate the need for further research.

    This paper examines the pervasive role of Microsoft’s presentation software PowerPoint as a genre of professional and organizational communication. Frequently, PowerPoint is not only used for the primary function it was initially designed for, i.e., facilitating live presentations, but also...... for alternative purposes such as project documentation. Its application in a neighboring domain, however, poses a functional dilemma: does the PowerPoint genre preserve the features of its primary function, i.e., presentation, or rather adapt to the new function, i.e., documentation? By drawing on a communication......-centered perspective, this paper examines PowerPoint’s role in the domain of project documentation as a clash between the constitutive affordances of professional and of organizational communication.

    Science.gov (United States)

    Collins, Jannette

    2004-01-01

    Effectiveness of an oral presentation depends on the ability of the speaker to communicate with the audience. An important part of this communication is focusing on two to five key points and emphasizing those points during the presentation. Every aspect of the presentation should be purposeful and directed at facilitating learners' achievement of the objectives. This necessitates that the speaker has carefully developed the objectives and built the presentation around attainment of the objectives. The best presentations are rehearsed, not so that the speaker memorizes exactly what he or she will say, but to facilitate the speaker's ability to interact with the audience and portray a relaxed, professional, and confident demeanor. Rehearsal also helps alleviate stage fright. The most useful method of controlling nervousness is to visualize success. When showing images, it is important to orient the audience with an adequate description, point out the relevant findings, and allow enough time for the audience to assimilate the information before moving on. This can be facilitated with appropriate use of a laser pointer, cursor, or use of builds and transitioning. A presentation should be designed to include as much audience participation as possible, no matter the size of the audience. Techniques to encourage audience participation include questioning, brainstorming, small-group activities, role-playing, case-based examples, and directed listening. It is first necessary to motivate and gain attention of the learner for learning to take place. This can be accomplished through appropriate use of humor, anecdotes, and quotations. Attention should be given to posture, body movement, eye contact, and voice when speaking, as how one appears to the audience will have an impact on their reaction to what is presented.

  12. International conference on opportunities and challenges for water cooled reactors in the 21. century. PowerPoint presentations

    International Nuclear Information System (INIS)

    2009-01-01

    Water Cooled Reactors have been the keystone of the nuclear industry in the 20th Century. As we move into the 21st Century and face new challenges such as the threat of climate change or the large growth in world energy demand, nuclear energy has been singled out as one of the sources that could substantially and sustainably contribute to power the world. As the nuclear community worldwide looks into the future with the development of advanced and innovative reactor designs and fuel cycles, it becomes important to explore the role Water Cooled Reactors (WCRs) will play in this future. To support the future role of WCRs, substantial design and development programmes are underway in a number of Member States to incorporate additional technology improvements into advanced nuclear power plants (NPPs) designs. One of the key features of advanced nuclear reactor designs is their improved safety due to a reduction in the probability and consequences of accidents and to an increase in the operator time allowed to better assess and properly react to abnormal events. A systematic approach and the experience of many years of successful operation have allowed designers to focus their design efforts and develop safer, more efficient and more reliable designs, and to optimize plant availability and cost through improved maintenance programs and simpler operation and inspection practices. Because many of these advanced WCR designs will be built in countries with no previous nuclear experience, it is also important to establish a forum to facilitate the exchange of information on the infrastructure and technical issues associated with the sustainable deployment of advanced nuclear reactors and its application for the optimization of maintenance of operating nuclear power plants. This international conference seeks to be all-inclusive, bringing together the policy, economic and technical decision-makers and the stakeholders in the nuclear industry such as operators, suppliers

  16. The Rhetoric of PowerPoint

    Directory of Open Access Journals (Sweden)

    Jens E. Kjeldsen

    2006-12-01

    Full Text Available The presentation program PowerPoint is probably the most used tool in the schools, high schools and universities of today. The use of this program, however, comes at a cost, because it is not just a different and neutral way of teaching. Like the use of any technology, PowerPoint affects not only the way we present and teach, but also the way we think, learn and understand. The program carries an inherent tendency to crate fragmentation of thought and cognitive overload. In order to avoid this we should stop thinking in terms of technology and begin to think rhetorically. What we need is media rhetoracy: the ability to communicate persuasively and appropriately.

In our technologically advanced world, electronic presentations have become the norm and are almost universally expected. Microsoft PowerPoint is by far and away the most commonly used computer-based presentation package. As a result most radiologists have developed at least a modicum of PowerPoint expertise but many lack the time or inclination to develop these skills further. The purpose of this article is to explain how to expand the use of PowerPoint with freely available resources from the internet, to highlight websites where useful information on advanced PowerPoint techniques can be found, and to discuss extended functions of PowerPoint likely to be of interest to radiologists such as poster design

    Teaching and learning process is increasingly metamorphosing from the traditional chalk and talk to the modern dynamism in the information and communication technology. Medical education is no exception to this dynamism more especially in the teaching of gross anatomy, which serves as one of the bases of understanding the human structure. This study was conducted to determine the gender preference of preclinical medical students on the use of traditional (chalk and talk) and PowerPoint presentation in the teaching of gross anatomy. This was cross-sectional and prospective study, which was conducted among preclinical medical students in the University of Maiduguri, Nigeria. Using simple random techniques, a questionnaire was circulated among 280 medical students, where 247 students filled the questionnaire appropriately. The data obtained was analyzed using SPSS version 20 (IBM Corporation, Armonk, NY, USA) to find the method preferred by the students among other things. Majority of the preclinical medical students in the University of Maiduguri preferred PowerPoint method in the teaching of gross anatomy over the conventional methods. The Cronbach alpha value of 0.76 was obtained which is an acceptable level of internal consistency. A statistically significant association was found between gender and preferred method of lecture delivery on the clarity of lecture content where females prefer the conventional method of lecture delivery whereas males prefer the PowerPoint method, On the reproducibility of text and diagram, females prefer PowerPoint method of teaching gross anatomy while males prefer the conventional method of teaching gross anatomy.

    Mathematics is a core subject in most of the science and technology courses and in some social sciences programs. However, the low achievement of students in the subject especially in topics such as Differentiation and Integration is always an issue. Many factors contribute to the low performance such as motivation, environment, method of learning, academic background and others. The purpose of this paper is to determine the perception of learning mathematics using PowerPoint on Integration concepts at the undergraduate level with respect to mathematics anxiety, learning enjoyment, mobility and learning satisfaction. The main content of the PowerPoint presentation focused on the integration method with historical elements as an added value. The study was conducted on 48 students randomly selected from students in computer and applied sciences program as experimental group. Questionnaires were distributed to students to explore their learning experiences. Another 51 students who were taught using the traditional chalkboard method were used as the control group. Both groups were given a test on Integration. The statistical methods used were descriptive statistics and independent sample t-test between the experimental and the control group. The finding showed that most students perceived positively to the PowerPoint presentations with respect to mobility and learning satisfaction. The experimental group performed better than the control group.

  17. Combining Chalk Talk with PowerPoint to Increase In-class Student Engagement

    Full Text Available In striving to attain a higher degree of in-class student engagement, and target a larger number of preferred student-learning styles, this case study describes a multimodal teaching approach. PowerPoint slides have gradually gained popularity over the more traditional chalk and talk lecture design. The student population in today’s age seeks more non-passive modes of information delivery. Numerous novel approaches to enhance active learning, such as flipped classroom and problem-based learning, have recently been explored. While working well for therapeutic and lab-based courses, these formats may not be best-suited for all basic science topics. The importance of basic science in a pharmacy curriculum is well emphasized in the 2016 ACPE Standards. To actively involve students in a pharmacology lecture on diuretics, a session was designed to combine the PowerPoint and chalk talk approaches. Students created 10 concept diagrams following an instructor, who explained each step in the process using a document camera. For visual learners, these diagrams provided a layered representation of the information, gradually increasing in complexity. For learners with a preference for the reading learning style, the information was also available in corresponding PowerPoint slides. Scores from pre- and post-session quizzes indicated a high level of concept understanding and recall (median 1 [IQR 0 – 2] vs 4 [IQR 3 – 5]; p<0.001. The student perception survey data reported higher in-class attention levels (76%, an appreciation for the utility of self-created concept diagrams (88%, and a call for additional sessions being presented in this format (73%. Targeting a variety of student learning styles by using the active development of concept diagrams, in addition to traditional PowerPoint slides, can promote student engagement and enhance content understanding.   Type: Case Study

    2004-12-01

    Course management systems (CMS) like WebCT, Blackboard, Astronomica, etc., have reached and surpassed their tipping point in higher education. They are no longer a technology-trendy item to use in a course, but rather an expected supplement to undergraduate courses. There is a well known disconnect between the student population of ''digital natives'' (1) and higher education instructors, the ''digital immigrants'' (1). What expectations and technology skills do the new generations of undergraduates have? How can instructors easily meet their students' needs? What needs do instructors have and what resources are available to meet those needs? In the past, instructors would create their own HTML web pages to post class materials like PowerPoint slides, homework, and announcements. How does an instructor-created web resource differ from a secure university run CMS? How can you make your university or college's CMS system into a productive learning tool and not just a repository for class materials and grades? How can the astronomy instructor benefit from integrating a CMS into their course? What are common student attitudes regarding CMS usage in a course? How are instructors using CMSs in innovative ways? Where on your campus can you get free help designing and implementing a CMS resource for your students? This presentation aims to answer these questions. Extensive literature reviews, formal surveys, case study reports, and educational research from the instructional technology community inform our astronomy teaching community of the answers. Highlights from innovative systems and uses of CMSs in undergraduate Astro 101 classrooms will be presented. Resources and further references will be made available as handouts. (1) M. Prensky.

    Our objective is to present a simple method for converting movie clips to animated GIFs (graphics interchange format) using Photoshop. Although animated GIF is a more reliable format than movie clips (e.g., AVI and QuickTime) for presenting dynamic data sets in PowerPoint presentations, this output format is not available on most radiology workstations. Therefore, many academic radiologists still experience the problem of incompatible codecs and missing file links when trying to show movie clips in their PowerPoint presentations. One way to resolve this issue is to convert the movie clips to animated GIFs. In this article, we provide a simple method for this conversion using Photoshop--a common software application used by radiologists.

    PowerPoint (PPT™) presentation has become an integral part of day-to-day teaching in medicine. Most often, PPT™ is used in its default mode which in fact, is known to cause boredom and ineffective learning. Research has shown improved short-term memory by applying multimedia principles for designing and delivering lectures. However, such evidence in medical education is scarce. Therefore, we attempted to evaluate the effect of multimedia principles on enhanced learning of parasitology. Second-year medical students received a series of lectures, half of the lectures used traditionally designed PPT™ and the rest used slides designed by Mayer's multimedia principles. Students answered pre and post-tests at the end of each lecture (test-I) and an essay test after six months (test-II) which assessed their short and long term knowledge retention respectively. Students' feedback on quality and content of lectures were collected. Statistically significant difference was found between post test scores of traditional and modified lectures (P = 0.019) indicating, improved short-term memory after modified lectures. Similarly, students scored better in test II on the contents learnt through modified lectures indicating, enhanced comprehension and improved long-term memory (P learning through multimedia designed PPT™ and suggested for their continued use. It is time to depart from default PPT™ and adopt multimedia principles to enhance comprehension and improve short and long term knowledge retention. Further, medical educators may be trained and encouraged to apply multimedia principles for designing and delivering effective lectures.

    Psoriasis is a chronic skin disease affecting approximately 125 million people worldwide. Currently, dermatologists monitor changes of psoriasis by clinical evaluation or by measuring psoriasis severity scores over time which lead to Subjective management of this condition. The goal of this paper is to develop a reliable assessment system to quantitatively assess the changes of erythema and intensity of scaling of psoriatic lesions. A smartphone deployable mobile application is presented that uses the smartphone camera and cloud-based image processing to analyze physiological characteristics of psoriasis lesions, identify the type and stage of the scaling and erythema. The application targets to automatically evaluate Psoriasis Area Severity Index (PASI) by measuring the severity and extent of psoriasis. The mobile application performs the following core functions: 1) it captures text information from user input to create a profile in a HIPAA compliant database. 2) It captures an image of the skin with psoriasis as well as image-related information entered by the user. 3) The application color correct the image based on environmental lighting condition using calibration process including calibration procedure by capturing Macbeth ColorChecker image. 4) The color-corrected image will be transmitted to a cloud-based engine for image processing. In cloud, first, the algorithm removes the non-skin background to ensure the psoriasis segmentation is only applied to the skin regions. Then, the psoriasis segmentation algorithm estimates the erythema and scaling boundary regions of lesion. We analyzed 10 images of psoriasis images captured by cellphone, determined PASI score for each subject during our pilot study, and correlated it with changes in severity scores given by dermatologists. The success of this work allows smartphone application for psoriasis severity assessment in a long-term treatment.

    Artificial intelligence (AL) techniques have been introduced actively in the nuclear industry in pursuit of increased safety and efficiency. The present report outlines some AI techniques currently used in nuclear facilities. This type of techniques have increasingly been introduced to such areas as design, construction, operation, maintenance, quality control and analysis. Most of them use knowledge engineering techniques including expert systems. Positive efforts at research and application of various more advance AI techniaues have started recently. For application of AI techniques, activities in nuclear power plants can be divided into two groups. One includes 'analytical' activities such as operation, maintenance and analysis, while the other includes 'synthetic' activities such as design, construction and fuel control. The most important AI technology for the analytical activities is diagnosis. Thus the report outlines major processes to which diagnostic techniques are applicable, and knowledge description and inference methods used for diagnosis. For AI techniques for synthetic activities, some problems and possible solutions are addressed. Development efforts in and outside Japan are also outlined. (Nogami, K.)

    2010-01-01

    To comply with international standards, independent leak monitoring systems should be installed based on the monitoring of different physical parameters capable of detecting any small leak within one hour from the start of the leak. Such leak detection systems are based mainly on acoustic emission monitoring, humidity monitoring and/or radiation monitoring. Advanced systems integrate the monitoring of different physical parameters into one integrated leak detection system. The Integrated Leak Detection System (ILDS) for NPP Metsamor is described. This system consists of three independent leak detection subsystems, viz. LEMOP (LEak MOnitoring of Pipelines) based on acoustic emission monitoring, HUMOS (HUmidity MOnitoring System) based on humidity monitoring, and RAMOS (RAdiation MOnitoring System) based on radiation monitoring). The Integrated Leak Detection System (ILDS) collects data from the three systems, performs data evaluation, data storage, generates alarms and provides a user interface for the whole system including all subsystems. An example of DiagAssist user interface in the ILDS system in the pictorial form. (P.A.)

    2017-02-01

    To establish detection schemes in life science applications, specific and sensitive methods allowing for fast detection times are required. Due to the interaction of molecules with strong electromagnetic fields excited at metallic nanostructures, the molecular fingerprint specific Raman spectrum is increased by several orders of magnitude. This effect is described as surface-enhanced Raman spectroscopy (SERS) and became a very powerful analytical tool in many fields of application. Within this presentation, we will introduce innovative bottom-up strategies to prepare SERS-active nanostructures coated with a lipophilic sensor layer. To do so, the food colorant Sudan III, an indirect carcinogen substance found in chili powder, palm oil or spice mixtures, is detected quantitatively in the background of the competitor riboflavin as well as paprika powder extracts. The SERS-based detection of azorubine (E122) in commercial available beverages with different complexity (e.g. sugar content, alcohol concentration) illustrates the strong potential of SERS as a qualitative as well as semiquantitative prescan method in food analytics. Here, a good agreement between the estimated concentration employing SERS as well as the gold standard technique HPLC, a highly laborious method, is found. Finally, SERS is applied to detect vitamin B2 and B12 in cereals as well as the estimate the ratio of lycopene and β-carotene in tomatoes.

  7. Presentation on mechanisms and applications of chalcopyrite and pyrite bioleaching in biohydrometallurgy - a presentation.

    2014-12-01

    This review outlines classic and current research, scientific documents and research achievements in bioleaching, particularly in respect of the bioleaching of chalcopyrite and pyrite. The diversity and commonality of the microbial leaching process can be easily studied through comparing the bioleaching mechanism and the application of these two metal sulfides. The crystal, electronic and surface structures of chalcopyrite and pyrite are summarized in detail in this paper. It determines the specific and complicated interaction pathways, kinetics of the atmospheric/aqueous oxidation, and the control process of bioleaching of the minerals as the precondition. Bioleaching of metal sulfides is performed by a diverse group of microorganisms and microbial communities. The species of the bacteria which have a significant effect on leaching ores are miraculously diverse. The newly identified acidophilic microorganisms with unique characteristics for efficient bioleaching of sulfidic minerals are increasing sharply. The cell-to-cell communication mechanisms, which are still implicit, elusive and intangible at present day, have gradually become a research hotspot. The different mineralogy characteristics and the acid solubility of the metal sulfides (e.g., chalcopyrite and pyrite) cause two different dissolution pathways, the thiosulfate and the polysulfide pathways. The bioleaching mechanisms are categorized by contact (an electrostatic attachment) and noncontact (planktonic) process, with emphasis on the produce of extracellular polymeric substances and formation of biofilm on the surface of the metal sulfides in this paper. The division of the direct and indirect effect are not adopted due to the redox chain, the reduction of the ferric iron and oxidation of the ferrous iron. The molecular oxygen is reduced by the electrons extracted from the specific metal sulfide, via a redox chain forming a supercomplex spanning the periplasmic space and connecting both outer and inner

    The Institute for Nuclear Safety and Protection (IPSN) is in charge of research in phenomenology of severe accidents which are not taken into account in the design basis but which could occur on the dfferent types of reactor operated in France. Related potential applications are varied and include: - assessment of radioactive release as to nature, quantity and kinetics, in order to validate the population evacuation plans, - analysis of the efficiency of the procedures and corrective actions envisaged by the operating utilities to minimize the consequences of severe accidents, - general risk surveys for the PRA programs. In order to carry out this task effectively, the IPSN has developed a set of computer programs to model on the one hand, the physics of fission product transfers (release from damaged fuel, vapour and aerosol behavior, transport outside the reactor containment), and on the other hand, the core, primary system and containment thermal hydraulics (including the incidence of safeguard systems, ultimate emergency procedures and corium-concrete interaction) determining fission product transfer kinetics. The system is completed by provision for modelling fission product atmophere, aquatic and hydrological transfers outside the containment. This computer program, known as ESCADRE, is presented in this paper

    When waves travel through disordered media such as ground glass and skin tissues, they are scattered multiple times. Most of the incoming energy bounces back at the superficial layers and only a small fraction can penetrate deep inside. This has been a limiting factor for the working depth of various optical techniques. We present a systematic method to enhance wave penetration to the scattering media. Specifically, we measured the reflection matrix of a disordered medium with wide angular coverage for each orthogonal polarization states. From the reflection matrix, we identified reflection eigenchannels of the medium, and shaped the incident wave into the reflection eigenchannel with smallest eigenvalue, which we call anti-reflection mode. This makes reflectance reduced and wave penetration increased as a result of the energy conservation. We demonstrated transmission enhancement by more than a factor of 3 by the coupling of the incident waves to the anti-reflection modes. Based on the uneven distribution of eigenvalues of reflection eigenchannels, we further developed an iterative feedback control method for finding and coupling light to anti-reflection modes. Since this adaptive control method can keep up with sample perturbation, it promotes the applicability of exploiting reflection eigenchannels. Our approach of delivering light deep into the scattering media will contribute to enhancing the sensitivity of detecting objects hidden under scattering layers, which is universal problem ranging from geology to life science.

    2016-09-01

    Multifunctional nanoconstructs are particle-based nano-scale systems designed for the `smart' delivery of therapeutic and imaging agents. The Laboratory of Nanotechnology for Precision Medicine at the Italian Institute of Technology synthesizes polymeric nanoconstructs with different sizes, ranging from a few tens of nanometers to a few microns; shapes, including spherical, cubical and discoidal; surface properties, with positive, negative, neutral coatings; and mechanical stiffness, varying from that of cells to rigid, inorganic materials, such as iron oxide. These are the 4S parameters - size, shape, surface, stiffness - which can be precisely tuned in the synthesis process enabling disease- and patient-specific designs of multifunctional nanoconstructs. In this lecture, the application of these nanoconstructs to the detection and treatment of cancer lesions and cardiovascular diseases, such as thrombosis and atherosclerosis, is discussed. The contribution of the 4S parameters in modulating nanoconstruct sequestration by the mononuclear phagocyte system, organ specific accumulation, and blood longevity is also critically presented. These polymeric nanoconstructs can be loaded with a variety of therapeutic payloads - anti-cancer molecules (docetaxel, paclitaxel, doxorubicin), anti-inflammatory molecules (curcumin, diclofenac, celecoxib) and small biologicals (peptides, siRNAs, miRNAs); and imaging agents - optical probes; Gd and iron oxide nanoparticles for MR imaging; and radio-isotopes for Nuclear Imaging.

    The history and present status of the utilization of RI tracers for hydrology are described by dividing into surface water and groundwater. By the birth of nuclear reactors, the availability of RIs became easy, and the utilization of tracers for hydrology has been attempted worldwide. The large scale development of water resources is required for increasing agricultural production, and the analysis of the actual condition of hydrological phenomena is indispensable for the purpose. The hydrology committee of IAEA aided the development of new techniques in the peaceful use of atomic energy, and let developing countries use the developed techniques together with researchers. The research on the field application of RI tracers in Japan began in agriculture, and the investigation of water leak in dams, the measurement of flow rate and flow velocity in rivers, the detection of the state of sand movement on sea bottom, the analysis of groundwater flow and so on have been carried out. Also the recent situation in foreign countries is reported about the measurement of flow rate, the measurement of flowing-down time and diffusion, the analysis of the behavior of lake water, the movement of mud and sediment, and the analysis of groundwater flow.

    Full Text Available In the present edition of Significação – Scientific Journal for Audiovisual Culture and in the others to follow something new is brought: the presence of thematic dossiers which are to be organized by invited scholars. The appointed subject for the very first one of them was Radio and the invited scholar, Eduardo Vicente, professor at the Graduate Course in Audiovisual and at the Postgraduate Program in Audiovisual Media and Processes of the School of Communication and Arts of the University of São Paulo (ECA-USP. Entitled Radio Beyond Borders the dossier gathers six articles and the intention of reuniting works on the perspectives of usage of such media as much as on the new possibilities of aesthetical experimenting being build up for it, especially considering the new digital technologies and technological convergences. It also intends to present works with original theoretical approach and original reflections able to reset the way we look at what is today already a centennial media. Having broadened the meaning of “beyond borders”, four foreign authors were invited to join the dossier. This is the first time they are being published in this country and so, in all cases, the articles where either written or translated into Portuguese.The dossier begins with “Radio is dead…Long live to the sound”, which is the transcription of a thought provoking lecture given by Armand Balsebre (Autonomous University of Barcelona – one of the most influential authors in the world on the Radio study field. It addresses the challenges such media is to face so that it can become “a new sound media, in the context of a new soundscape or sound-sphere, for the new listeners”. Andrew Dubber (Birmingham City University regarding the challenges posed by a Digital Era argues for a theoretical approach in radio studies which can consider a Media Ecology. The author understands the form and discourse of radio as a negotiation of affordances and

    2001-01-01

    In Brazil the long-term continuous cultivation of sugarcane with low N fertiliser inputs, without apparent depletion of soil-N reserves, led to the suggestion that N 2 -fixing bacteria associated with the plants may be the source of agronomically significant N inputs to this crop. From the 1950s to 1970s, considerable numbers of N 2 -fixing bacteria were found to be associated with the crop, but it was not until the late 1980s that evidence from N balance and 15 N dilution experiments showed that some Brazilian varieties of sugarcane were able to obtain significant contributions from this source. The results of these studies renewed the efforts to search for N 2 -fixing bacteria, but this time the emphasis was on those diazotrophs that infected the interior of the plants. Within a few years several species of such 'endophytic diazotrophs' were discovered including Gluconacetobacter diazotrophicus, Herbaspirillum seropedicae, H. rubrisubalbicans and Burkholderia sp. Work has continued on these endophytes within sugarcane plants, but to date little success has been attained in elucidating which endophyte is responsible for the observed BNF and in what site, or sites, within the cane plants the N 2 fixation mainly occurs. Until such important questions are answered further developments or extension of this novel N 2 -fixing system to other economically important non-legumes (e.g. cereals) will be seriously hindered. As far as application of present knowledge to maximise BNF with sugarcane is concerned, molybdenum is an essential micronutrient. An abundant water supply favours high BNF inputs, and the best medium term strategy to increase BNF would appear to be based on cultivar selection on irrigated N deficient soils fertilised with Mo.

    2017-02-01

    My research focuses on the use of computation/algorithms to create new optical microscopy, sensing, and diagnostic techniques, significantly improving existing tools for probing micro- and nano-objects while also simplifying the designs of these analysis tools. In this presentation, I will introduce a set of computational microscopes which use lens-free on-chip imaging to replace traditional lenses with holographic reconstruction algorithms. Basically, 3D images of specimens are reconstructed from their "shadows" providing considerably improved field-of-view (FOV) and depth-of-field, thus enabling large sample volumes to be rapidly imaged, even at nanoscale. These new computational microscopes routinely generate benefit of this technology is that it lends itself to field-portable and cost-effective designs which easily integrate with smartphones to conduct giga-pixel tele-pathology and microscopy even in resource-poor and remote settings where traditional techniques are difficult to implement and sustain, thus opening the door to various telemedicine applications in global health. Through the development of similar computational imagers, I will also report the discovery of new 3D swimming patterns observed in human and animal sperm. One of this newly discovered and extremely rare motion is in the form of "chiral ribbons" where the planar swings of the sperm head occur on an osculating plane creating in some cases a helical ribbon and in some others a twisted ribbon. Shedding light onto the statistics and biophysics of various micro-swimmers' 3D motion, these results provide an important example of how biomedical imaging significantly benefits from emerging computational algorithms/theories, revolutionizing existing tools for observing various micro- and nano-scale phenomena in innovative, high-throughput, and yet cost-effective ways.

    Perhaps one of the most intriguing aspects of nanotechnology is the ability to create multimodal and multifunctional nanostructures that can open new venues in solving challenging biomedical problems. Here, we present multimodal magneto-plasmonic nanoparticles (MPNs) with a strong red-NIR absorbance, superparamagnetic properties and a high magnetic moment in an external magnetic field. Our design is based on self-assembly of 6 nm primary particles which consist of 5 nm diameter iron-oxide cores coated with a very thin ca. 0.5 nm gold shell. The assembly results in spherical highly uniform MPNs. We developed antibody targeted MPNs to address two highly challenging applications: (i) development of real-time assays for capture, enumeration and characterization of circulating tumor cells (CTCs), and (ii) enhancement of adoptive cell immunotherapy (ACT). Our results showed that MPNs can be used for simultaneous magnetic capture and photoacoustic (PA) detection of cancer cells in whole blood with no laborious processing steps. Furthermore, we demonstrated that MPNs conjugated with anti-CD8 antibodies, which are specific for cytotoxic T cells used in ATC, label CD8+ T cells with high specificity ex vivo and in vivo. Labeled T cells can be easily manipulated by a small magnet in suspension and under flow conditions. In addition, MPNs generate high contrast in MRI and PA imaging with the potential to detect just few cells per imaging voxel. These results show that immunotargeted MPNs can be explored for simultaneous visualization and magnetic guidance of T cell subsets in vivo for cancer treatment.

    2015-09-01

    Full Text Available Microbial exopolysaccharides (EPS have found outstanding medical applications since the mid-twentieth century, with the first clinical trials on dextran solutions as plasma expanders. Other EPS entered medicine firstly as conventional pharmaceutical excipients (e.g., xanthan - as suspension stabilizer, or pullulan – in capsules and oral care products. Polysaccharides, initially obtained from plant or animal sources, became easily available for a wide range of applications, especially when they were commercially produced by microbial fermentation. Alginates are used as anti-reflux, dental impressions, or as matrix for tablets. Hyaluronic acid and derivatives are used in surgery, arthritis treatment or wound healing. Bacterial cellulose is applied in wound dressings or scaffolds for tissue engineering. The development of drug controlled-release systems and of micro- and nanoparticulated ones, has opened a new era of medical applications for biopolymers. EPS and their derivatives are well suited potentially non-toxic, biodegradable drug carriers. Such systems concern rating and targeting of controlled release. Their large area of applications is explained by the available manifold series of derivatives, whose useful properties can be thereby controlled. From matrix inclusion to conjugates, different systems have been designed to solubilize, and to assure stable transport in the body, target accumulation and variable rate-release of a drug substance. From controlled drug delivery, EPS potential applications expanded to vaccine adjuvants and diagnostic imaging systems. Other potential applications are related to the bioactive (immunomodulator, antitumor, antiviral characteristics of EPS. The numerous potential applications still wait to be developed into commercial pharmaceuticals and medical devices. Based on previous and recent results in important medical-pharmaceutical domains, one can undoubtedly state that EPS medical applications have a

    Liquid crystalline semiconductor is an interesting category of organic electronic materials and also has been extensively studied in terms of "Printed Electronics". For the wider diversity in research toward new applications, one can consider how to use a combination of miscibility and phase separation in liquid crystals. Here we report discotic liquid crystals in making a composite of which structural order is controlled in nano-scale toward photovoltaic applications. Discotic columnar LCs were studied on their resultant molecular order and carrier transport properties. Liquid crystals of phthalocyanine and its analogues which exhibit columnar mesomorphism with high carrier mobility (10-1 cm2/Vs) were examined with making binary phase diagrams and the correlation to carrier transport properties by TOF measurements was discussed. The shape-analogues in chemical structure shows a good miscibility even for the different lattice-type of columnar arrangement and the carrier mobility is mostly decrease except for a case of combination with a metal-free and the metal complex. For the mixtures with non-mesogenic C60 derivatives, one sees a phase-separated structure due to its immiscibility, though the columnar order is remained in a range of component ratio.Especially, in a range of the ratio, it was observed the phase separated C60 derivatives are fused into the matrix of columnar bundles, indicating C60 derivatives could be diffused in columnar arrays in molecular level.

    1970-01-01

    This is the fourth in a series of symposia which started, in 1957 at Livermore with the purpose of examining the peaceful uses of nuclear explosives. Although principal emphasis has b een placed on technological applications, the discussions have, from the outset, included the fascinating question of scientific uses. Of the possible scientific applications which were mentioned at the 1957 meeting, the proposals which attracted most attention involved uses of nuclear explosions for research in seismology.

    This is the fourth in a series of symposia which started, in 1957 at Livermore with the purpose of examining the peaceful uses of nuclear explosives. Although principal emphasis has {sup b}een placed on technological applications, the discussions have, from the outset, included the fascinating question of scientific uses. Of the possible scientific applications which were mentioned at the 1957 meeting, the proposals which attracted most attention involved uses of nuclear explosions for research in seismology.

    2004-01-01

    In this study the sections of human tissues were treated under 9.5 μm FEL in the BFEL based on the vibrational spectroscopic investigation that significant differences occur between normal and malignant tissues. Under the defocus condition, the burning of tissue section at some part while other part remains unchanged, suggesting that the FEL can selectively destroy some part of tissue. Vibrational spectroscopic and microscopic methods have shown that the FEL can induce decomposition of malignant tissues. The application of FEL whose wavelength is on the characteristic bands of malignant tissues may provide a new method to kill cancer cells with higher selectivity. For understanding the interactions between FEL and biological tissues, structure changes of substances under irradiation by FEL of 9.414 μm and 6.228 μm were measured using FTIR spectroscopy. The samples include ATP, ADP, AMP, and D-ribose, etc. The FTIR spectra of the molecules before and after irradiation of FEL indicate...

    The presentation begins with the role and need for nuclear repositories (overall concept, international updates (Sweden, Finland, France, China), US approach and current status), then moves on to the WIPP TRU repository concept (design, current status--safety incidents of February 5 and 14, 2014, path forward), and finally considers the WIPP safety case: dissolved actinide concentrations (overall approach, oxidation state distribution and redox control, solubility of actinides, colloidal contribution and microbial effects). The following conclusions are set forth: (1) International programs are moving forward, but at a very slow and somewhat sporadic pace. (2) In the United States, the Salt repository concept, from the perspective of the long-term safety case, remains a viable option for nuclear waste management despite the current operational issues/concerns. (3) Current model/PA prediction (WIPP example) are built on redundant conservatisms. These conservatisms are being addressed in the ongoing and future research to fill existing data gaps--redox control of plutonium by Fe(0, II), thorium (analog) solubility studies in simulated brine, contribution of intrinsic and biocolloids to the mobile concentration, and clarification of microbial ecology and effects.

  13. Light in flight photography and applications (Conference Presentation)

    Science.gov (United States)

    Faccio, Daniele

    2017-02-01

    The first successful attempts (Abramson) at capturing light in flight relied on the holographic interference between the ``object'' beam scattered from a screen and a short reference pulse propagating at an angle, acting as an ultrafast shutter cite{egg}. This interference pattern was recorded on a photographic plate or film and allowed the visualisation of light as it propagated through complex environments with unprecedented temporal and spatial resolution. More recently, advances in ultrafast camera technology and in particular the use of picosecond resolution streak cameras allowed the direct digital recording of a light pulse propagating through a plastic bottle (Rasker at el.). This represented a remarkable step forward as it provided the first ever video recording (in the traditional sense with which one intends a video, i.e. something that can be played back directly on a screen and saved in digital format) of a pulse of light in flight. We will discuss a different technology that is based on an imaging camera with a pixel array in which each individual pixel is a single photon avalanche diode (SPAD). SPADs offer both sensitivity to single photons and picosecond temporal resolution of the photon arrival time (with respect to a trigger event). When adding imaging capability, SPAD arrays can deliver videos of light pulse propagating in free space, without the need for a scattering medium or diffuser as in all previous work (Gariepy et al). This capability can then be harnessed for a variety of applications. We will discuss the details of SPAD camera detection of moving objects (e.g. human beings) that are hidden from view and then conclude with a discussion of future perspectives in the field of bio-imaging.

    Purpose To assess students’ perceptions of the impact of PowerPoint (PPT) presentations in lectures in comparison to the traditional chalk and talk method and lectures using transparencies and overhead projector (TOHP). The study analyzes the preferences for teaching aids of medical students versus dental students. Methods Second year medical and dental undergraduates were asked to fill in a nine-item questionnaire about their perceptions of the three lecture delivery methods. Following analysis of the questionnaire the students were interviewed further. The results were analyzed separately for medical and dental students to see if there was any difference in their perceptions. Results The majority of the medical students (65.33%) preferred PPT presentations, while 15.16% of students preferred the lectures using chalkboard, and 19.51% preferred TOHP for teaching (P lectures (P lecture delivery method. It appears that in the hands of a trained teacher any teaching aid would be appropriate and effective. This highlights the need for formal training in teaching technologies to develop good presentation skills and thus motivate the students. PMID:23745057

  16. History and present status of field application of radiotracers, (2)

    International Nuclear Information System (INIS)

    Koyama, Takeo; Shimizu, Makoto.

    1988-01-01

    In the field of agriculture, radiotracers were first used in 1957 in studies for improvement in fertilizing techniques. Techniques were established for accurate measurement of extremely low radioactivity in crops and for the separate determination of the phosphorus in crops of the fertilizer origin and soil origin. Then, RI or stable isotope tracing test methods were developed using 32 P or 15 N to determine the flow and absorption of fertilizers. Other techniques using radiotracers developed in this period served for the construction of maps of the root activity of crops, investigation of the effects of different fertilizers in farms where double-cropping was practised, identification of suitable fertilizers for orange cultivation, development of new fertilizing techniques for Japanese persimmon cultivation, etc. Practically, no field use of radiotracers has been found since 1970. At present, it is prohibited and replaced by other techniques using stable isotopes, etc. In the field fishery, radiotracers have been used for studies of various dynamic phenomena including the flow of water and deposits in the sea, behaviors of fish, food, chain, circulation of chemical substances in the ecological system, etc. (Nogami, K.)

  17. Present status of radiation application on irradiation service

    2006-01-01

    Presently, it is in operation 6 gamma-ray facilities and 5 electron beam (EB) facilities for an irradiation service. New gamma-ray facility is under construction, and will be worked in August this year. These facilities are generally employed for crosslinking and decomposition of polymers, graft polymerization, improvement of semiconductor properties, sterilization of medical devices, laboratory-animals feed, packing materials and biotechnological devices. As for being feature one of EB facilities is employed only for improvement of polymers and semiconductors. Approximately 91% of gamma-ray sterilization of medical devices is processed in house, and 5 facilities are working in 4 firms. Other two firms have 4 EB facilities for sterilization. Therefore, the degree of dependence of irradiation service is low in the sterilization of medical devices. About 50% of medical devices are still sterilized by ethylene oxide gas (EOG). However, a part of laws has been amended successively from 5 years ago, and the regulation of EOG handling became harsh. Therefore, EOG sterilization will be gradually displaced in radiation sterilization. On the other hand, demand for sterilization of the packing materials has increased significantly, and various kinds of packing materials in food industry are sterilized by both gamma-rays and EB. Currently, novel PMMA dosimeter was developed and named Radix W. The dosimeter allows measurement of doses from 1 kGy to 150 kGy without influence of dose rates and irradiation temperature. The activities of irradiation service probably will continue to increase over future. (author)

    2016-11-01

    Full Text Available Photovoltaic (PV systems have non-linear characteristics that generate maximum power at one particular operating point. Environmental factors such as irradiance and temperature variations greatly affect the maximum power point (MPP. Diverse offline and online techniques have been introduced for tracking the MPP. Here, to track the MPP, an augmented-state feedback linearized (AFL non-linear controller combined with an artificial neural network (ANN is proposed. This approach linearizes the non-linear characteristics in PV systems and DC/DC converters, for tracking and optimizing the PV system operation. It also reduces the dependency of the designed controller on linearized models, to provide global stability. A complete model of the PV system is simulated. The existing maximum power-point tracking (MPPT and DC/DC boost-converter controller techniques are compared with the proposed ANN method. Two case studies, which simulate realistic circumstances, are presented to demonstrate the effectiveness and superiority of the proposed method. The AFL with ANN controller can provide good dynamic operation, faster convergence speed, and fewer operating-point oscillations around the MPP. It also tracks the global maxima under different conditions, especially irradiance-mutating situations, more effectively than the conventional methods. Detailed mathematical models and a control approach for a three-phase grid-connected intelligent hybrid system are proposed using MATLAB/Simulink.

    2018-04-09

    The residential photovoltaic (PV) market has expanded rapidly over the past decade, but questions exist about how equitably that growth has occurred across income groups. Prior studies have investigated this question but are often limited by narrow geographic study regions, now-dated analysis timeframes, or coarse estimates of PV-adopter incomes. At the same time, a spate of new programs and initiatives, as well as innovations in business models and product design, have emerged in recent years with the aim of making solar more accessible and affordable to broader segments of the population. Yet, many of those efforts are proceeding without robust underlying information about the income characteristics of recent residential PV adopters. This work aims to establish basic factual information about income trends among U.S. residential solar adopters, with some emphasis on low- and moderate-income (LMI) households. The analysis is unique in its relatively extensive coverage of the U.S. solar market, relying on Berkeley Lab’s Tracking the Sun dataset, which contains project-level data for the vast majority of all residential PV systems in the country (a subset of which are ultimately included in the analysis sample). This analysis is also unique in its use of household-level income estimates that provide a more-precise characterization of PV-adopter incomes than in most prior studies.

  16. Strain Analysis of Stretched Tourmaline Crystals Using ImageJ, Microsoft Excel and PowerPoint

    Bosbyshell, H.

    2012-12-01

    This poster describes an undergraduate structural geology lab exercise utilizing the Mohr's circle diagram for finite strain, constructed using measurements obtained from stretched tourmaline crystals. A small building housing HVAC equipment at the south end of West Chester University's Recitation Hall (itself made of serpentinite) is constructed of early-Cambrian Chickies Quartzite. Stretched tourmaline crystals, with segments joined by fibrous quartz, are visible on many surfaces (presumably originally bedding). While the original orientation of any stone is unknown, these rocks provide an opportunity for a short field exercise during a two-hour lab period and a great base for conducting strain analysis. It is always fun to ask how many in the class have ever noticed the tourmaline (few have). Students take photos using their cell phones or cameras. Since strain is a ratio the absolute size of the tourmaline crystals is immaterial. Nonetheless, this is a good opportunity to remind students of the importance of including a scale in their photographs. The photos are opened in ImageJ and the line tool is used to determine the original and final lengths of selected crystals. Students calculate strain parameters using Microsoft Excel. Then, we use Adobe Illustrator or the drafting capabilities of Microsoft PowerPoint 2010 to follow Ramsay and Huber's techniques using a Mohr's circle construction to determine the finite strain ellipse. If a stretching direction can be estimated, elongation of two crystals is all that is required to determine the strain ratio. If no stretching direction is apparent, three crystals are required for a more complicated analysis that allows for determination of the stretching direction, as well as the strain ratio.

    2008-06-01

    Radioisotopes continue to play an important role in better management of natural resources, industrial growth and environmental preservation. The success of radioisotope applications is due primarily to the ability, conferred by the unique properties of radioactive materials, to collect data, where conventional methods fail or become uneconomical. These are prompt, on-line, in-situ and do not disturb the main industrial process in any way. In Sudan, the application of these nuclear techniques has considerable economic and environmental impact. This paper casts light on the present application of radioisotopes and future trends in the country.(Author)

    Different multidisciplinary therapeutic strategies and technical approaches are used today in cancer therapy. Among the techniques involving ionizing radiation, therapeutic applications of radioactive nuclides deserve a particular interest ; some clinical indications are well established, while several others are now being investigated, and some of them are promising. The efficacy of radionuclides in therapy often depends on technical factors such as specific activity, purity, chemical presentation, availability, etc. These factors are closely related, at least partly, to the production methods. This justifies the organization of the present Consultant's meeting by the IAEA. Brief information on cancer, its socio-economic aspects, and some data concerning cure rate are presented first

    This paper introduces Pyff, the Pythonic feedback framework for feedback applications and stimulus presentation. Pyff provides a platform-independent framework that allows users to develop and run neuroscientific experiments in the programming language Python. Existing solutions have mostly been implemented in C++, which makes for a rather tedious programming task for non-computer-scientists, or in Matlab, which is not well suited for more advanced visual or auditory applications. Pyff was designed to make experimental paradigms (i.e., feedback and stimulus applications) easily programmable. It includes base classes for various types of common feedbacks and stimuli as well as useful libraries for external hardware such as eyetrackers. Pyff is also equipped with a steadily growing set of ready-to-use feedbacks and stimuli. It can be used as a standalone application, for instance providing stimulus presentation in psychophysics experiments, or within a closed loop such as in biofeedback or brain-computer interfacing experiments. Pyff communicates with other systems via a standardized communication protocol and is therefore suitable to be used with any system that may be adapted to send its data in the specified format. Having such a general, open-source framework will help foster a fruitful exchange of experimental paradigms between research groups. In particular, it will decrease the need of reprogramming standard paradigms, ease the reproducibility of published results, and naturally entail some standardization of stimulus presentation.

    A variety of sources contribute to nutrients in rivers and nutrients may subsequently take various pathways and undergo different transformation processes. We first review representative types of isotopes and the roles of isotope techniques that have been or could be used for nutrient assessment and management. We then present technical, financial and logistical matters to be considered in selecting appropriate isotope techniques for nutrient assessment and management. Lastly we propose several approaches on the application of isotope techniques to make more effective the studies and management of nutrients in rivers in the near future. (author)

  11. The World-Wide Web past present and future, and its application to medicine

    CERN Document Server

    Sendall, D M

    1997-01-01

    The World-Wide Web was first developed as a tool for collaboration in the high energy physics community. From there it spread rapidly to other fields, and grew to its present impressive size. As an easy way to access information, it has been a great success, and a huge number of medical applications have taken advantage of it. But there is another side to the Web, its potential as a tool for collaboration between people. Medical examples include telemedicine and teaching. New technical developments offer still greater potential in medical and other fields. This paper gives some background to the early development of the World-Wide Web, a brief overview of its present state with some examples relevant to medicine, and a look at the future.

    In Canada, there exists a mature research programme directed towards resolving the nuclear safety and licensing questions surrounding fission product iodine. This integrated programme has had the long term objectives of developing a mechanistic understanding of the important aspects of iodine behaviour in containment, and of producing a mechanistic computer code to predict iodine behaviour under conditions of interest. The research is funded by Canadian Utilities and AECL through the CANDU Owners Group. In parallel with the research, an applications effort is underway to put existing research results into service for the resolution of reactor safety and licensing issues, as well as to identify and develop solutions for more comprehensive problems, such as chemical mitigation strategies to control post-accident iodine release. The present paper describes (a) the present status and objectives of R and D on iodine, its recent evolution and its significant achievements, (b) the analytical tools that are emerging from this programme and (c) existing and planned future applications of the results of the iodine R and D programme. The author concludes with an assessment of the impact that the iodine programme has had on reactor safety and licensing questions in Canada

    The objective of the present study was to develop a scientifically sound rationale for the application of infrared laser radiation (IRLR) either separately or in the combination with fluctuation magnetic therapy in the medical rehabilitation of the children presenting with chronic hematogenous osteomyelitis. Another objective was to evaluate the clinical effectiveness of this therapeutic modality. Two achieve these goals, the clinical observations and special research studies were conducted in two directions with the participation of 95 patients at the age varying from 1 to 15 years. The study has demonstrated the effectiveness of the inclusion of IRLR in the medical rehabilitation program for the children with chronic hematogenous osteomyelitis in different periods of the disease. It was shown that the transcutaneous infrared irradiation of the affected area during the exacerbation of chronic osteomyelitis had a well apparent immunostimulatory effect and reduced the activity of the inflammatory process. The application of IRLR in combination with fluctuation magnetic therapy during the period of partial remission, had a more pronounced influence on the microcirculation and stimulated the regenerative and trophic processes.

    2013-08-15

    Food security is becoming a crucial concern worldwide. In this study, we focus on wheat - a staple crop in China - as a model to review its history, status quo and future scenarios, with regard to key production technologies and management practices for wheat production and associated food security issues since the new era in China: the post-1949 era. First, the dominant technologies and management practices over the past 60 years are reviewed. Secondly, we outline several key innovative technologies and their theoretical bases over the last decade, including (i) prohibiting excessively early senescence at a later growth stage to maintain viable leaves with higher photosynthetic capacity, (ii) postponing top dressing nitrogen application to balance carbon and nitrogen nutrition, and (iii) achieving both high yield and better grain quality mainly by increasing soil productivity and balancing the ratio of nutrient elements. Finally, concerns such as water shortages and excessive application of chemical fertilizers are presented. Nevertheless, under high negative conditions, including global warming, rapid population growth, decreasing amounts of arable land, increasing competition with cash crops and severe environmental pollution, we conclude that domestic food production will be able to meet Chinese demand in the mid to long term, because increasingly innovative technologies and improved management practices have been and may continue to be applied appropriately. © 2013 Society of Chemical Industry.

    The value chain (VC) is a major operational concept for socioeconomic analysis at meso level. Widely mobilized in development practice, it is still undergoing conceptual and practical refining, e.g., to take account of environmental and social sustainability. Briefly, VC refers to a system of value creation through the full set of actors, links, technical and commercial activities and flows involved in the provision of a good or service on a market. In the past decade, this concept has been promoted in the management of animal health. In particular, the emergence of highly pathogenic avian influenza (HPAI) has triggered an interdisciplinary dynamic including VC analysis as a central tool. These efforts promoted participatory investigation methods in the analysis of health systems. Using qualitative and quantitative data, these methods acknowledge the usefulness of actors' involvement and knowledge, hence facilitating the transdisciplinarity needed for effective action. They fit into adaptive and action-oriented strategies, fostering stakeholders' participation. Recent research on HPAI surveillance in South-East Asia merged VC and participatory approaches to develop innovative tools for analyzing constraints to information flow. On-going interventions for HPAI prevention and control as well as the prevention of other emerging zoonotic risks in Africa are presently building on this VC framework to develop strategies for its application at national and regional scales. Based on the latter experiences, this article proposes a field-based perspective on VC applications to animal and public health systems, within a One Health approach responding to the overall challenge of complexity.

    We will present our last development of GMR-based magnetic sensors devoted to sensing application for non-destructive control application. In these first realizations, we have chosen a so-called shape anisotropy - exchange biased strategy to fulfill the field-sensing criteria in the μT range in devices made of micronic single elements. Our devices realized by optical lithography, and whose typical sizes range from 150 μm x 150 μm to 500 μm x 500 μm elements, are made of trilayers GMR-based technology and consist of several circuitries of GMR elements of different lengths, widths and gaps. To obtain a full sensing linearity and reversibility requiring a perpendicular magnetic arrangement between both sensitive and hard layer, the magnetization of the latter have been hardened by pinning it with an antiferromagnetic material. The specific geometry of the design have been engineered in order to optimize the magnetic response of the soft layer via the different magnetic torques exerted on it essentially played by the dipolar fields or shape anisotropy, and the external magnetic field to detect. The smaller dimensions in width and in gap are then respectively of 2 μm and 3 μm to benefit of the full shape anisotropy formatting the magnetic response.

    The current need to understand iodine chemistry in a reactor safety context has become more sharply focussed as the level of that understanding has advanced. At the same time, the situations of most concern within containment, from an iodine perspective, are also being redefined in the light of that understanding. The present paper summarises these developments. Over the past five years, considerable advances have occurred in our understanding of iodine chemistry under conditions of interest in reactor accidents. A number of key experiments have yielded important results in the areas of solution chemistry, the role of surfaces, the importance of organics and the effects of impurities. This understanding supplements the already substantial gains made in characterising the key roles of pH and the effects of radiation. All these factors underline the now evident fact that the kinetics of iodine are the controlling factor when radiation is involved, and that a number of reactive species, not present in thermal reactions, effectively control the observed volatility of iodine. In this paper, recent advances are summarised and the present status of our understanding of iodine chemistry is reviewed. Specifically, an attempt is made to identify those areas where our understanding appears to be relatively complete, and to flag the remaining critical areas where our attention is currently focussed. The state of our modelling capability is reviewed, as is the significance or related areas such as the role of mass transfer. Finally, an overview is presented of the significance of this work for reactor safety, and our expectations for its application over the near term future. (author) 2 figs., 12 refs.

  6. Near-infrared (NIR) emitting conjugated polymers for biomedical applications (Presentation Recording)

    Repenko, Tatjana; Kuehne, Alexander J. C.

    2015-10-01

    Fluorescent biomedical markers of today such as dye-infiltrated colloids, microgels and quantum dots suffer from fast bleaching, lack surface functionality (for targets or pharmaceutical agents) and potentially leach heavy metals in case of quantum dots (e.g. Cd). By contrast, conjugated polymer particles are non-cytotoxic, exhibit reduced bleaching, as the entire particle consists of fluorophore, they are hydrophobic and show high quantum yields. Consequently, conjugated polymer particles represent ideal materials for biological applications and imaging. However currently, conjugated polymer particles for biomedical imaging usually lack near-infrared (NIR) emission and are polydisperse. Fluorescent agents with emission in the NIR spectrum are interesting for biomedical applications due to their low photo-damage towards biological species and the ability of NIR radiation to penetrate deep into biological tissue.. I will present the development and synthesis of new conjugated polymers particles with fluorescence in the NIR spectral region for bio-imaging and clinical diagnosis. The particle synthesis proceeds in a one-step Pd or Ni-catalyzed dispersion polymerization of functional NIR emitters. The resulting monodisperse conjugated polymer particles are obtained as a dispersion in a non-hazardous solvent. Different sizes in the sub-micrometer range with a narrow size distribution can be produced. Furthermore biological recognition motifs can be easily attached to the conjugated polymers via thiol-yne click-chemistry providing specific tumor targeting without quenching of the fluorescence.

    We report the application of ultrafast rotational coherent anti-Stokes Raman scattering (CARS) for temperature and relative oxygen concentration measurements in the plume emanating from a burning aluminized ammonium perchlorate propellant strand. Combustion of these metal-based propellants is a particularly hostile environment for laserbased diagnostics, with intense background luminosity, scattering and beam obstruction from hot metal particles that can be as large as several hundred microns in diameter. CARS spectra that were previously obtained using nanosecond pulsed lasers in an aluminumparticle- seeded flame are examined and are determined to be severely impacted by nonresonant background, presumably as a result of the plasma formed by particulateenhanced laser-induced breakdown. Introduction of fs/ps laser pulses enables CARS detection at reduced pulse energies, decreasing the likelihood of breakdown, while simultaneously providing time-gated elimination of any nonresonant background interference. Temperature probability densities and temperature/oxygen correlations were constructed from ensembles of several thousand single-laser-shot measurements from the fs/ps rotational CARS measurement volume positioned within 3 mm or less of the burning propellant surface. Preliminary results in canonical flames are presented using a hybrid fs/ps vibrational CARS system to demonstrate our progress towards acquiring vibrational CARS measurements for more accurate temperatures in the very high temperature propellant burns.

    Drug-coated balloon (DCB) technologies represent the latest and hottest development in the field of endovascular treatment of peripheral arterial disease. Initial experience with paclitaxel-coated balloon use in the femoral artery has demonstrated lower mid-term restenosis and superior mid-term clinical outcomes in terms of improved wound healing and reduced repeat angioplasty rates compared with standard balloon angioplasty. Many companies are presently developing and/or improving DCB catheters and therefore ongoing, technical improvements of the already existing platforms, new drugs, and innovative carriers are expected. The ongoing basic research studies and various multicenter randomized, controlled trials that are currently in progress will offer valuable scientific insights regarding the long-term effectiveness and other crucial issues, such as efficacy in various vascular beds, optimal balloon dosage, and post angioplasty antiplatelet therapy. Future applications of these devices also could include in-stent restenosis, anastomotic stenosis of surgical bypass, and benign stenoses of the central venous system.

    Drug-coated balloon (DCB) technologies represent the latest and hottest development in the field of endovascular treatment of peripheral arterial disease. Initial experience with paclitaxel-coated balloon use in the femoral artery has demonstrated lower mid-term restenosis and superior mid-term clinical outcomes in terms of improved wound healing and reduced repeat angioplasty rates compared with standard balloon angioplasty. Many companies are presently developing and/or improving DCB catheters and therefore ongoing, technical improvements of the already existing platforms, new drugs, and innovative carriers are expected. The ongoing basic research studies and various multicenter randomized, controlled trials that are currently in progress will offer valuable scientific insights regarding the long-term effectiveness and other crucial issues, such as efficacy in various vascular beds, optimal balloon dosage, and post angioplasty antiplatelet therapy.

    Cerumen or earwax is an emerging bio-fluid in clinical diagnosis that has been very little exploited during the past decades in spite of its high diagnostic potential. It is highly abundant in diagnostic biomarkers such as genetic material, lipids, proteins, chemical elements, internal and external metabolites ( e.g. hormones, volatile organic compounds, amino acids, xenobiotics etc. ) reaching earwax from the blood circulation. Thus, it is able to reflect not only physiology, pathophysiology of the human body but can also detect recent and long term exposure to environmental pollutants, without the need of invasive blood tests and in the same time overcoming many disadvantages faced by using other diagnostic biological fluids. This review discusses the biology, functions, chemistry of earwax, past and current approaches for the study of its chemical composition, emphasizing how a detected variation in its composition can offer information of high clinical value, which can be useful in diagnosis of many diseases such as metabolic disorders and tumours as well as in forensic applications. It also presents details about techniques of sample collection, storage, and analysis. Moreover, it highlights concerns about the use of earwax for diagnostic purposes, which should be addressed to make earwax diagnostics a reality in the future.

  18. Terahertz thickness measurements for real industrial applications: from automotive paints to aerospace industry (Conference Presentation)

    Science.gov (United States)

    Krimi, Soufiene; Beigang, René

    2017-02-01

    In this contribution, we present a highly accurate approach for real-time thickness measurements of multilayered coatings using terahertz time domain spectroscopy in reflection geometry. The proposed approach combines the benefits of a model-based material parameters extraction method to calibrate the specimen under test, a generalized modeling method to simulate the terahertz radiation behavior within arbitrary thin films, and the robustness of a powerful evolutionary optimization algorithm to increase the sensitivity and the precision of the minimum thickness measurement limit. Furthermore, a novel self-calibration model is introduced, which takes into consideration the real industrial challenges such as the effect of wet-on-wet spray in the car painting process and the influence of the spraying conditions and the sintering process on ceramic thermal barrier coatings (TBCs) in aircraft industry. In addition, the developed approach enables for some applications the simultaneous determination of the complex refractive index and the coating thickness. Hence, a pre-calibration of the specimen under test is not required for such cases. Due to the high robustness of the self-calibration method and the genetic optimization algorithms, the approach has been successfully applied to resolve individual layer thicknesses within multi-layered coated samples down to less than 10 µm. The regression method can be applied in time-domain, frequency-domain or in both the time and frequency-domain simultaneously. The data evaluation uses general-purpose computing on graphics processing units and thanks to the developed highly parallelized algorithm lasts less than 300 ms. Thus, industrial requirements for fast thickness measurements with an "every-second-cycle" can be fulfilled.

    Nanocellulose, extracted from the most abundant biomass material cellulose, has proved to be an environmentally friendly material with excellent mechanical performance owing to its unique nano-scaled structure, and has been used in a variety of applications as engineering and functional materials. The great biocompatibility and biodegradability, in particular, render nanocellulose promising in biomedical applications. In this review, the structure, treatment technology and properties of three different nanocellulose categories, i.e., nanofibrillated cellulose (NFC), nanocrystalline cellulose (NCC) and bacterial nanocellulose (BNC), are introduced and compared. The cytotoxicity, biocompatibility and frontier applications in biomedicine of the three nanocellulose categories were the focus and are detailed in each section. Future prospects concerning the cytotoxicity, applications and industrial production of nanocellulose are also discussed in the last section.

    2007-01-01

    This paper presents a newly established database of the European power plant infrastructure (power plants, fuel infrastructure, fuel resources and CO 2 storage options) for the EU25 member states (MS) and applies the database in a general discussion of the European power plant and natural gas infrastructure as well as in a simple simulation analysis of British and German power generation up to the year 2050 with respect to phase-out of existing generation capacity, fuel mix and fuel dependency. The results are discussed with respect to age structure of the current production plants, CO 2 emissions, natural gas dependency and CO 2 capture and storage (CCS) under stringent CO 2 emission constraints. The analysis of the information from the power plant database, which includes planned projects, shows large variations in power plant infrastructure between the MS and a clear shift to natural gas-fuelled power plants during the last decade. The data indicates that this shift may continue in the short-term up to 2010 since the majority of planned plants are natural gas fired. The gas plants are, however, geographically concentrated to southern and northwest Europe. The data also shows large activities in the upstream gas sector to accommodate the ongoing shift to gas with pipelines, liquefaction plants and regasification terminals being built and gas fields being prepared for production. At the same time, utilities are integrating upwards in the fuel chain in order to secure supply while oil and gas companies are moving downwards the fuel chain to secure access to markets. However, it is not yet possible to state whether the ongoing shift to natural gas will continue in the medium term, i.e. after 2010, since this will depend on a number of factors as specified below. Recently there have also been announcements for construction of a number of new coal plants. The results of the simulations for the German and British power sector show that combination of a relatively low

  5. Medical students' preferences in radiology education a comparison between the Socratic and didactic methods utilizing powerpoint features in radiology education.

    The Socratic method has long been a traditional teaching method in medicine and law. It is currently accepted as the standard of teaching in clinical wards, while the didactic teaching method is widely used during the first 2 years of medical school. There are arguments in support of both styles of teaching. After attending a radiology conference demonstrating different teaching methods, third-year and fourth-year medical students were invited to participate in an online anonymous survey. Of the 74 students who responded, 72% preferred to learn radiology in an active context. They preferred being given adequate time to find abnormalities on images, with feedback afterward from instructors, and they thought the best approach was a volunteer-based system of answering questions using the Socratic method in the small group. They desired to be asked questions in a way that was constructive and not belittling, to realize their knowledge deficits and to have daily pressure to come prepared. The respondents thought that pimping was an effective teaching tool, supporting previous studies. When teaching radiology, instructors should use the Socratic method to a greater extent. Combining Socratic teaching with gentle questioning by an instructor through the use of PowerPoint is a preferred method among medical students. This information is useful to improve medical education in the future, especially in radiology education. Copyright © 2011 AUR. Published by Elsevier Inc. All rights reserved.

    Despite the worldwide economic meltdown during the past two years and preceding any stimulus program projects, the market for electrostatic accelerators has increased on three fronts: new applications developed in an expanding range of fields; technical enhancements that increase the range, precision, and sensitivity of existing systems; and new accelerator projects in a growing number of developing countries. From the single application of basic nuclear structure research from the 1930's into the 1970's, the continued expansion of new applications and the technical improvements in electrostatic accelerators have dramatically affected the configurations and capabilities of accelerator systems to meet new requirements. This paper describes examples of recent developments in cosmology, exotic materials, high resolution RBS, compact AMS, dust acceleration, ion implantation, etc.

    Full Text Available Many central nervous system (CNS diseases including stroke, spinal cord injury (SCI, and brain tumors are a significant cause of worldwide morbidity/mortality and yet do not have satisfying treatments. Cell-based therapy to restore lost function or to carry new therapeutic genes is a promising new therapeutic approach, particularly after human iPSCs became available. However, efficient generation of footprint-free and xeno-free human iPSC is a prerequisite for their clinical use. In this paper, we will first summarize the current methodology to obtain footprint- and xeno-free human iPSC. We will then review the current iPSC applications in therapeutic approaches for CNS regeneration and their use as vectors to carry proapoptotic genes for brain tumors and review their applications for modelling of neurological diseases and formulating new therapeutic approaches. Available results will be summarized and compared. Finally, we will discuss current limitations precluding iPSC from being used on large scale for clinical applications and provide an overview of future areas of improvement. In conclusion, significant progress has occurred in deriving iPSC suitable for clinical use in the field of neurological diseases. Current efforts to overcome technical challenges, including reducing labour and cost, will hopefully expedite the integration of this technology in the clinical setting.

    2014-04-07

    Novel, partially bio-based poly(vinyl ether) copolymers derived from soybean oil and cyclohexyl vinyl ether (CHVE) were produced by cationic polymerization and investigated for application as alkyd-type surface coatings. Compared to conventional alkyd resins, which are produced by high temperature melt condensation polymerization, the poly(vinyl ether)s provide several advantages. These advantages include miler, more energy efficient polymer synthesis, elimination of issues associated with gelation during polymer synthesis, production of polymers with well-defined composition and relatively narrow molecular weight distribution, and elimination of film formation and physical property issues associated with entrained monomers, dimers, trimmers, etc. The results of the studied showed that the thermal, mechanical, and physical properties of the coatings produced from these novel polymers varied considerable as a function of polymer composition and cure temperature. Overall, the results suggest a good potential for these novel copolymers to be used for coatings cured by autoxidation.

    2017-05-01

    This contribution is focused on the numerical studies of resonant processes in individual plasmonic nanostructures, with the attention particularly given to rectangular nanoparticles and concominant localized surface plasmon resonance processes. Relevant models for the description and anylysis of localized surface plasmon resonance are introduced, in particular: quasistatic approximation, Mie theory and in particular, a generalized (quasi)analytical approach for treating rectangularly shaped nanostructures. The parameters influencing resonant behavior of nanoparticles are analyzed with special interest in morphology and sensor applications. Results acquired with Lumerical FDTD Solutions software, using finite-difference time-domain simulation method, are shown and discussed. Simulations were mostly performed for selected nanostructures composed of finite rectangular nanowires with square cross-sections. Systematic analysis is made for single nanowires with varying length, parallel couple of nanowires with varying gap (cut -wires) and selected dolmen structures with varying gap between one nanowire transversely located with respect to parallel couple of nanowires (in both in-plane and -out-of-plane arrangements). The dependence of resonant peaks of cross-section spectral behavior (absorption, scattering, extinction) and their tunability via suitable structuring and morphology changes are primarily researched. These studies are then followed with an analysis of the effect of periodic arrangements. The results can be usable with respect to possible sensor applications.

    Full Text Available Abstract Many studies are currently investigating the development of safe and effective vaccines to prevent various infectious diseases. Multiple antigen-presenting peptide vaccine systems have been developed to avoid the adverse effects associated with conventional vaccines (i.e., live-attenuated, killed or inactivated pathogens, carrier proteins and cytotoxic adjuvants. Recently, two main approaches have been used to develop multiple antigen-presenting peptide vaccine systems: (1 the addition of functional components, e.g., T-cell epitopes, cell-penetrating peptides, and lipophilic moieties; and (2 synthetic approaches using size-defined nanomaterials, e.g., self-assembling peptides, non-peptidic dendrimers, and gold nanoparticles, as antigen-displaying platforms. This review summarizes the recent experimental studies directed to the development of multiple antigen-presenting peptide vaccine systems.

    People use social media resources like Twitter, Facebook, forums etc. to share and discuss various activities or topics. By aggregating topic trends across many individuals using these services, we seek to construct a richer profile of a person’s activities and interests as well as provide a broader context of those activities. This profile may then be used in a variety of ways to understand groups as a collection of interests and affinities and an individual’s participation in those groups. Our approach considers that much of these data will be unstructured, free-form text. By analyzing free-form text directly, we may be able to gain an implicit grouping of individuals with shared interests based on shared conversation, and not on explicit social software linking them. In this paper, we discuss a proof-of-concept application called Grandmaster built to pull short sections of text, a person’s comments or Twitter posts, together by analysis and visualization to allow a gestalt understanding of the full collection of all individuals: how groups are similar and how they differ, based on their text inputs.

    High-throughput actinic mask inspection tools are needed as EUVL begins to enter into volume production phase. One of the key technologies to realize such inspection tools is a high-radiance EUV source of which radiance is supposed to be as high as 100 W/mm2/sr. Ushio is developing laser-assisted discharge-produced plasma (LDP) sources. Ushio's LDP source is able to provide sufficient radiance as well as cleanliness, stability and reliability. Radiance behind the debris mitigation system was confirmed to be 120 W/mm2/sr at 9 kHz and peak radiance at the plasma was increased to over 200 W/mm2/sr in the recent development which supports high-throughput, high-precision mask inspection in the current and future technology nodes. One of the unique features of Ushio's LDP source is cleanliness. Cleanliness evaluation using both grazing-incidence Ru mirrors and normal-incidence Mo/Si mirrors showed no considerable damage to the mirrors other than smooth sputtering of the surface at the pace of a few nm per Gpulse. In order to prove the system reliability, several long-term tests were performed. Data recorded during the tests was analyzed to assess two-dimensional radiance stability. In addition, several operating parameters were monitored to figure out which contributes to the radiance stability. The latest model that features a large opening angle was recently developed so that the tool can utilize a large number of debris-free photons behind the debris shield. The model was designed both for beam line application and high-throughput mask inspection application. At the time of publication, the first product is supposed to be in use at the customer site.

    This talk focuses on preparation, characterization and micropatterning of electrically conducting KETJENBLACK carbon black nanoparticle (80 nm-diameter) doped Polydimethylsiloxane (PDMS) by employing extrusion mixing. Previously, we had reported fabrication of various micropatternable nanocomposites for wearable sensing applications vis solvent assisted ultrasonic mixing technique[1-16] . Extrusion mixing has an advantage as no organic solvents are used and homogenous dispersion of carbon nanoparticles is observed, which is confirmed by SEM analysis. The developed nanocomposite can be micropatterened using standard microfabrication techniques. It is also observed that percolation threshold occurs at 0.51 wt% of carbon nanoparticles in polymer matrix. Examples of developed nano-composites for wearable sensing applications for precision medicine will also be discussed. References: 1.http://summit.sfu.ca/item/12017 A. Khosla.

    Recent advances in inkjet-printed optics have created a new class of lens fabrication technique. Lenses with a tunable geometry, magnification, and focal length can be fabricated by dispensing controlled amounts of liquid polymer onto a heated surface. This fabrication technique is highly cost-effective, and can achieve optically smooth surface finish. Dubbed DotLens, a single of which weighs less than 50 mg and occupies a volume less than 50 μL. DotLens can be attached onto any smartphone camera akin to a contact lens, and enable smartphones to obtain image resolution as fine as 1 µm. The surface curvature modifies the optical path of light to the image sensor, and enables the camera to focus as close as 2 mm. This enables microscopic imaging on a smartphone without any additional attachments, and has shown great potential in mobile point-of-care diagnostic systems, particularly for histology of tissue sections and cytology of blood cells. DotLens Smartphone Microscopy represents an innovative approach fundamentally different from other smartphone microscopes. In this paper, we describe the application and performance of DotLens smartphone microscopy in biological and biomedical research. In particular, we show recent results from images collected from pathology tissue slides with cancer features. In addition, we show performance in cytological analysis of blood smear. This tool has empowered Citizen Science investigators to collect microscopic images from various interesting objects.

    2010-09-01

    Thermal spray has enjoyed unprecedented growth and has emerged as an innovative and multifaceted deposition technology. Thermal spray coatings are crucial to the enhanced utilization of various engineering systems. Industries, in recognition of thermal spray's versatility and economics, have introduced it into manufacturing environments. The majority of modern thermal spray applications are "passive" protective coatings, and they rarely perform an electronic function. The ability to consolidate dissimilar material multilayers without substrate thermal loading has long been considered a virtue for thick-film electronics. However, the complexity of understanding/controlling materials functions especially those resulting from rapid solidification and layered assemblage has stymied expansion into electronics. That situation is changing: enhancements in process/material science are allowing reconsideration for novel electronic/sensor devices. This review critically examines past efforts in terms of materials functionality from a device perspective, along with ongoing/future concepts addressing the aforementioned deficiencies. The analysis points to intriguing future possibilities for thermal spray technology in the world of thick-film sensors.

    Many challenges exist in understanding the human body as a whole, its adaptability, its resilience, its immunological response, its healing and regeneration power. New knowledge is usually obtained by exploring unique conditions and environments and space is one such variable. Primarily, these attributes have been studied in space for the purpose of understanding the effect of the space environment on long duration space travel. However a myriad of lessons learned have emerged that are important for terrestrial medicine problems such as cardiovascular changes, intracranial pressure changes, vision changes, reduced immunity, etc. For medical study purposes, the changes induced by the space environment on the human body are in general fast and predictable; they persist while in the space environment but also revert to the initial pre-flight healthy state upon return to Earth. This provides a unique cycle to study wellness and disease prediction as well as to develop more effective countermeasures for the benefit of people on earth. At a scientific level, the environment of space can be used to develop new lines of investigations and new knowledge to push the terrestrial state of the art (i.e. study of phase diagrams, identification of new system's states, etc). Moreover, the specialized requirements for space medicine have driven advances in terrestrial medical technologies in areas such as monitoring, diagnostic, prevention and treatment. This talk will provide an overview of compelling examples in key areas of interest for terrestrial medical applications.

Malfunctioning of RPE contributes to the onset and advance of retinal degenerative diseases. Up to date, RPE replacement therapy is the only possible method to completely reverse retinal degeneration. Transplantation of human RPE stem cell-derived RPE (hRPESC-RPE has shown some good results in animal models. With promising results in terms of safety and visual improvement, human embryonic stem cell-derived RPE (hESC-RPE can be expected in clinical settings in the near future. Despite twists and turns, induced pluripotent stem cell-derived RPE (iPSC-RPE is now being intensely investigated to overcome genetic and epigenetic instability. By far, only one patient has received iPSC-RPE transplant, which is a hallmark of iPSC technology development. During follow-up, no major complications such as immunogenicity or tumorigenesis have been observed. Future trials should keep focusing on the safety of stem cell-derived RPE (SC-RPE especially in long period, and better understanding of the nature of stem cell and the molecular events in the process to generate SC-RPE is necessary to the prosperity of SC-RPE clinical application.

    Full Text Available The authors have made an overview of the status of production of cement concrete using nanotechnologies. The authors also provide their analysis of domestic and foreign researches into the application of nanotechnologies in the field of building materials. The authors have picked out positive examples of introduction of nano-scale particles into the concrete mix. The process needs continuous monitoring for the composition and the mixing time to be adjustable. The findings have been solely made by local developers of nano-materials and technologies. The authors propose their method of cement consumption reduction through the introduction of nanoparticles and simultaneous grinding of cement. The authors provide a new procedure of treatment of materials that contemplates enhanced mixing processes accompanied by simultaneous grinding of materials and their exposure to the electromagnetic treatment. The experiments completed by the team of authors have proven the efficiency of a combination of two nanotechnologies within one process, including the treatment of wet cement at the final grinding stage of processing to ensure specific cement properties for a specific surface area of 8,000 cm2/g, and the introduction of nano-scale particles into the process of manufacturing of cement compositions. The use of carbon nanotubes in the process of manufacturing of cement concrete can improve its physical and mechanical properties and reduce the cement consumption rate while maintaining the design strength of concrete.

    Sweat is a biofluid with present scant use as clinical sample. This review tries to demonstrate the advantages of sweat over other biofluids such as blood or urine for routine clinical analyses and the potential when related to metabolomics. With this aim, critical discussion of sweat samplers and equipment for analysis of target compounds in this sample is made. Well established routine analyses in sweat as is that to diagnose cystic fibrosis, and the advantages and disadvantages of sweat versus urine or blood for doping control have also been discussed. Methods for analytes such as essential metals and xenometals, ethanol and electrolytes in sweat in fact constitute target metabolomics approaches or belong to any metabolomics subdiscipline such as metallomics, ionomics or xenometabolomics. The higher development of biomarkers based on genomics or proteomics as omics older than metabolomics is discussed and also the potential role of metabolomics in systems biology taking into account its emergent implementation. Normalization of the volume of sampled sweat constitutes a present unsolved shortcoming that deserves investigation. Foreseeable trends in this area are outlined. Copyright © 2013 Elsevier B.V.

  20. On the half-life of luminescence signals in dosimetric applications: A unified presentation

    Science.gov (United States)

    Pagonis, V.; Kitis, G.; Polymeris, G. S.

    2018-06-01

    Luminescence signals from natural and man-made materials are widely used in dosimetric and dating applications. In general, there are two types of half-lives of luminescence signals which are of importance to experimental and modeling work in this research area. The first type of half-life is the time required for the population of the trapped charge in a single trap to decay to half its initial value. The second type of half-life is the time required for the luminescence intensity to drop to half of its initial value. While there a handful of analytical expressions available in the literature for the first type of half-life, there are no corresponding analytical expressions for the second type. In this work new analytical expressions are derived for the half-life of luminescence signals during continuous wave optical stimulation luminescence (CW-OSL) or isothermal luminescence (ITL) experiments. The analytical expressions are derived for several commonly used luminescence models which are based on delocalized transitions involving the conduction band: first and second order kinetics, empirical general order kinetics (GOK), mixed order kinetics (MOK) and the one-trap one-recombination center (OTOR) model. In addition, half-life expressions are derived for a different type of luminescence model, which is based on localized transitions in a random distribution of charges. The new half-life expressions contain two parts. The first part is inversely proportional to the thermal or optical excitation rate, and depends on the experimental conditions and on the cross section of the relevant luminescence process. The second part is characteristic of the optical and/or thermal properties of the material, as expressed by the parameters in the model. A new simple and quick method for analyzing luminescence signals is developed, and examples are given of applying the new method to a variety of dosimetric materials. The new test allows quick determination of whether a set of

    The main advantages of this particular method for analyzing the reliability and safety of systems, the method of failure combinations, are presented. This is an inductive method of analysis; it makes it possible to pursue the Failure Modes and Effect Analysis (FMEA) until overall failures are obtained. In this manner, through an inductive approach all the combinations of failure modes leading to abnormal functioning of systems are obtained. It also makes it possible to carry out the overall study of complex systems in interaction and the systematic inventory of abnormal functioning of these systems, as from the failure modes of the components and their combinations. It can be used as from the design stages of systems and is an excellent dialogue tool between the various specialists concerned in problems of safety, operation and reliability [fr

    In January 2004, President Bush announced a new vision for space exploration. This included retirement of the current Space Shuttle fleet by 2010 and the development of new set of launch vehicles. The President's vision did not include significant increases in the NASA budget, so these development programs need to be cost conscious. Current trade study procedures address factors such as performance, reliability, safety, manufacturing, maintainability, operations, and costs. It would be desirable, however, to have increased insight into the cost factors behind each of the proposed system architectures. This paper reports on a set of component trade studies completed on the upper stage engine for the new launch vehicles. Increased insight into architecture costs was developed by including a Net Present Value (NPV) method and applying a set of associated risks to the base parametric cost data. The use of the NPV method along with the risks was found to add fidelity to the trade study and provide additional information to support the selection of a more robust design architecture.

    Within the European Union, the two major breeding blanket concepts presently being developed are the helium cooled pebble bed (HCPB), and the helium cooled lithium lead (HCLL) blankets. For both concepts, different conceptual designs are being discussed with temperature windows in the range 250-550 deg. C for conservative approaches based on reduced activation ferritic-martensitic (RAFM) steels, and in the range 250-650 deg. C for more advanced versions, taking into account oxide dispersion strengthened (ODS) steels. As a final result of a systematic development of RAFM-steels in Europe, the 9% CrWVTa alloy EUROFER was specified and produced in an industrial scale with a variety of product forms. A large characterisation program is being performed including irradiation in materials test reactors between 60 and 450 deg. C ({<=}15 dpa), and in a fast breeder reactor at 330 deg. C up to 30 dpa. EUROFER is resistant to high temperature ageing, and the existing creep-rupture data ({approx}30,000 h, 450-600 deg. C) indicate long-term stability and predictability. The ODS variant of EUROFER shows superior tensile and creep properties compared to EUROFER. Applying a new production route has diminished the problem of lower ductility and inferior impact properties. A reliable joining technique for ODS and RAFM steels employing diffusion welding was successfully developed.

    Vibrational spectroscopy encompasses a number of techniques and methods including ultra-violet, visible, Fourier transform infrared or mid infrared, near infrared and Raman spectroscopy. The use and application of spectroscopy generates spectra containing hundreds of variables (absorbances at each wavenumbers or wavelengths), resulting in the production of large data sets representing the chemical and biochemical wine fingerprint. Multivariate data analysis techniques are then required to handle the large amount of data generated in order to interpret the spectra in a meaningful way in order to develop a specific application. This paper focuses on the developments of sample presentation and main sources of error when vibrational spectroscopy methods are applied in wine analysis. Recent and novel applications will be discussed as examples of these developments. © 2014 Society of Chemical Industry.

    The purpose was to demonstrate compliance with the core design parameters and safety analyses and assess the results against safety criteria (compare the true values with the limiting levels used in safety analysis), design criteria (compare the true and predicted values), and realization criteria (confirm the test realization based on an approved procedure and acquisition of data necessary for its evaluation). Theoretical data were obtained by the KASKAD method. The experimental equipment is described with focus on the Physics Startup Control Board. The following experimental results are described: first criticality; symmetry assessment; isothermal temperature coefficient and moderator temperature coefficient (ITC, MTC); single bank worth; differential and integral worth boron reactivity coefficients; and emergency shutdown efficiency. It is concluded that despite problems that occurred and were assessed during the start-up, the test results demonstrated acceptability of further operation; the start-up test results demonstrated compliance with core design parameters and safety analyses, and therefore the operation is safe.

    Full Text Available This study examines the use of PowerPoint as a teaching tool in a workplace- embedded program aimed at bridging immigrant/refugee early childhood educators into post-secondary studies, and how, in the process, it shapes students’ “habits of mind” (Turkle, 2004. The premise of the study is that it is not only the bodies of knowledge shaping teacher education programs which must be interrogated, but also the ways in which instructors and programs choose to represent and impart these understandings to students. The use of PowerPoint to advance an authoritative western, linear, rule-governed form of logic is analyzed based on McLuhan and McLuhan’s (1988 and Adams’ (2006 tetrads. The findings demonstrate that Power- Point enhances western authoritative ways of being through its modes of communication and representation, means of organizing information, forms of representing content and pedagogical approaches, thus obsolescing or displacing immigrant/refugee students’ own indigenous ways of knowing. Since learning always involves the development, integration, and reorganization of tools, and the medium is an extension of the self (McLuhan, 2003, the students should have multimodal opportunities to engage with and represent knowledge. When such opportunities are not provided, the life experiences and cultural knowledges of immigrant/refugee students are silenced. Expanding communicative and representative forms in early childhood teacher education programs is necessary to promote a more inclusive environment.

    The rehabilitative treatment of the patients suffering from knee osteoarthrosis (OA) up-to-date remains one of the most important medical and social problems of modern medicine due to the high prevalence of this disease, heavy morbidity, and the significant deterioration of the quality of the patients' life. The objective of the present study was to evaluate the long-term results of the combined application of radon and extracorporeal shock-wave therapy for the rehabilitation of the patients presenting with knee OA. The study involved 75 patients at the age from 35 to 62 years with the confirmed diagnosis of stage II and III knee osteoarthrosis. They were divided into 3 groups. Those comprising the main group received extracorporeal shock-wave therapy in combination with the treatment based on the use of radon baths. The patients included in the group of comparison were given a course of radon therapy alone while the patients of the control group received the standard treatment including physiotherapy, magnetic therapy, and the use of non-steroidal anti-inflammatory drugs (NSAIDs). The study has demonstrated the high effectiveness of the combined application of the radon baths and extracorporeal shock-wave therapy that was manifested as the substantial decrease of pain intensity, the increased range of motion in the knee joints, and the improvement of the general quality of life. These beneficial effects persisted during a period of up to 12 months. The stable remission was documented in 82% of the patients comprising the main group. The data obtained give reason to recommend the method employed in the present study for the extensive practical application at different stages of medical rehabilitation of the patients presenting with knee osteoarthrosis.

    Osteoarthritis (OA) is currently considered to be one of the most widespread diseases. Its main clinical symptoms include pain and dysfunction of joints. In the present review of the foreign and domestic literature, the questions of pathogenesis and risk factors underlying the development of osteoarthritis are discussed. The understanding of OA pathogenesis have altered essentially in the recent years which made necessary the search for the novel approaches to the treatment of this pathology. According to the modern views of OA origin and progression, its therapy should be based on the application of the combination of medicamentous and non-medicamentous modalities including, in particular, collective and individual activities focused on the implementation of the programs of therapeutic physical training as an obligatory component of ОА prophylaxis and treatment. The present review gives evidence of the feasibility of the application of the methods of cryotherapy and radonotherapy for the management of the patients suffering from osteoarthritis. It is emphasized that many recent publications report extensive investigations of the clinical and pathogenetic aspects of the application of these methods for the combined regenerative treatment of the patients presenting with gonarthrosis. The influence of cryotherapy and radonotherapy on the neuroendocrine and immune systems is discussed with special reference to the possibility of regulation of the metabolic processes and retardation of inflammation. It is concluded that the introduction of the above methods into the compulsory individual program for the regenerative treatment of patients presenting with osteoarthritis is pathologically substantiated since it greatly contributes to the reduction of pain and retardation of the progress of the disease. The main pharmaceutical preparations for the OA treatment remain to be slow-acting symptomatic medicines possessed of the chondro-protective effect.

    The principal objective of the present work was to evaluate the influence of impulse magnetic therapy on the state of the microcirculatory system in the patients presenting with lymphedema of the lower extremities. The study included 59 patients with stage of 1 and 2 lymphedema who were divided into two groups. Those comprising the first group had impulse magnetic therapy applied to their lower extremities while the patients making up the second group served as controls. All the patients were examined with the use of the laser Doppler flowmetry (LDF) that revealed the initially present pathological changes in the microcirculatory system of their lower extremities. The study has demonstrated that the application of impulse magnetic therapy produced a positive effect on all the constituent components of the microcirculatory blood stream of the patients suffering from lymphedema of the lower extremities. Specifically, the initially increased arteriolar tonus was decreased, the blood flow in the capillary vessels was improved, and congestive phenomena in the venular segments of the microcirculation blood stream were markedly reduced. The results of the LDF examination in the control group gave no evidence of significant changes in the patients' microcirculatory system. The results of the LDF examination of the patients of the control group suggested the absence of any appreciable changes in the microcirculatory system. The present study has demonstrated the advisability of the application of impulse magnetic therapy for the treatment of the patients presenting with lymphedema of the lower extremities as a minimally invasive technique for the evaluation of the condition of the microcirculatory system and the objective assessment of the effectiveness of the outcomes of physiotherapy in the patients with vascular pathology.

    The problem of the development of the new efficient methods for the treatment of the patients presenting with chronic bacterial vesiculitis (CBV) is currently considered among the important priorities. The objective of the present study was to provide a scientifically sound substantiation for the application of sinusoidal modulated currents (SMC), magnetic fields, and laser radiation in the combined treatment of the patients with CBV. A total of 121 patients presenting with chronic bacterial vesiculitis were examined and treated during the latent phase of the inflammatory process. They were randomly divided into three groups. Group 1 (main) was comprised of 40 patients treated, in addition to basal pharmacotherapy, by supravascular contact laser irradiation of the cubital vein area followed after 2-3 hours by the application of sinusoidal modulated currents to the pubosacral region. Group 2 included 41patents given, besides basal pharmacotherapy, laser therapy in the same regimen as in group 1 supplemented after 2-3 hours by abdominal magnetic therapy. Group 3 (control) received traditional pharmacotherapy in the combination with antibacterial and anti-inflammatory medicines. It was demonstrated that the patients of group 2 exhibited the most pronounced positive dynamics of the clinical signs and symptoms estimated from the total National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI) and of the characteristics of the quality of life evaluated based on the QLS scale. The patients of the two former groups experienced a more conspicuous decrease in the activity of the inflammatory process in seminal vesicles, restoration of their structural and anatomical features (as shown by the transrectal ultrasound study), improvement of testosterone metabolism, and normalization of the spermogram characteristics in comparison with controls. The analysis of the spermograms revealed the tendency toward the increase in the number of actively motile spermatozoa

    2007-01-01

    These last years, the new irradiation techniques as the conformal 3D radiotherapy and the IMRT are strongly correlated with the technological developments in radiotherapy. The rigorous definition of the target volume and the organs at risk required by these irradiation techniques, imposed the development of various image guided patient positioning and target tracking techniques. The availability of these imaging systems inside the treatment room has lead to the exploration of performing real-time adaptive radiation therapy. In this paper we present the different image guided radiotherapy (IGRT) techniques and the adaptive radiotherapy (ART) approaches. IGRT developments are focused in the following areas: 1) biological imaging for better definition of tumor volume; 2) 4D imaging for modeling the intra-fraction organ motion; 3) on-board imaging system or imaging devices registered to the treatment machines for inter-fraction patient localization; and 4) treatment planning and delivery schemes incorporating the information derived from the new imaging techniques. As this paper is included in the 'Cancer Radiotherapie' special volume dedicated to the lung cancers, in the description of the different IGRT techniques we try to present the lung tumors applications when this is possible.

    2014-08-26

    This paper describes a sensor dedicated to measuring the vertical profile of the complex permittivity and the temperature of any medium in which sensor electrodes are inserted. Potential applications are the estimate of the humidity and salinity in a porous medium, such as a soil. It consists of vertically-stacked capacitors along two conductive parallel cylinders of 5 cm in diameter and at a 10-cm distance to scan a significant volume of the medium (~1 L). It measures their admittances owing to a self-balanced impedance bridge operating at a frequency in the range of 1-20 MHz, possibly 30 MHz. Thanks to accurate design and electronic circuit theory-based modeling, the determination of the admittances takes into account all distortions due to lead and bridge electromagnetic effects inside the sensor when working at high frequencies. Calibration procedures and uncertainties are presented. The article also describes developments to make the present sensor autonomous on digital acquisition, basic data treatment and energy, as well as able to transfer stored data by a radio link. These steps in progress are prerequisites for a wireless network of sensors.

    2014-01-31

    In November 2012, Oregon State University initiated the project entitled: Application of Crunch-Flow routines to constrain present and past carbon fluxes at gas-hydrate bearing sites. Within this project we developed Crunch-Flow based modeling modules that include important biogeochemical processes that need to be considered in gas hydrate environments. Our modules were applied to quantify carbon cycling in present and past systems, using data collected during several DOE-supported drilling expeditions, which include the Cascadia margin in US, Ulleung Basin in South Korea, and several sites drilled offshore India on the Bay of Bengal and Andaman Sea. Specifically, we completed modeling efforts that: 1) Reproduce the compositional and isotopic profiles observed at the eight drilled sites in the Ulleung Basin that constrain and contrast the carbon cycling pathways at chimney (high methane flux) and non-chimney sites (low methane, advective systems); 2) Simulate the Ba record in the sediments to quantify the past dynamics of methane flux in the southern Hydrate Ridge, Cascadia margin; and 3) Provide quantitative estimates of the thickness of individual mass transport deposits (MTDs), time elapsed after the MTD event, rate of sulfate reduction in the MTD, and time required to reach a new steady state at several sites drilled in the Krishna-Godavari (K-G) Basin off India. In addition we developed a hybrid model scheme by coupling a home-made MATLAB code with CrunchFlow to address the methane transport and chloride enrichment at the Ulleung Basins chimney sites, and contributed the modeling component to a study focusing on pore-scale controls on gas hydrate distribution in sediments from the Andaman Sea. These efforts resulted in two manuscripts currently under review, and contributed the modeling component of another pare, also under review. Lessons learned from these efforts are the basis of a mini-workshop to be held at Oregon State University (Feb 2014) to instruct

  20. Challenges and solutions of implementing and supporting wind diesel applications in remote (AK) locations

    Energy Technology Data Exchange (ETDEWEB)

    2010-07-01

    This PowerPoint presentation discussed the methods used by Northern Power Systems to install and support wind-diesel applications in remote locations in Alaska. Over 90 wind turbines have been installed in the state over the last 5 years. Drivers behind the increase in wind turbine installations include the recent energy crisis as well as the introduction of several financial incentives for renewable energy. The correct equipment is needed to overcome the technical challenges associated with wind-diesel systems in remote cold temperature areas. Multiple projects are synchronized within regions, and remote energy management software is used. Centralized power production is promoted where possible, and technicians are trained locally. The wind-diesel market has become successful in Alaska as a result of leadership, a streamline grant and permitting process, and a program that supports First Nations empowerment. Photographs of various Northern Power Systems projects in Alaska were included. tabs., figs.

    This PowerPoint presentation described a study conducted to test the effectiveness of surfactant-enhanced permanganate for the remediation of dense nonaqueous phase liquids (DNAPL). When DNAPL enters the environment, it can pollute millions of gallons of ground water and create huge dissolved plumes that act as long-term sources of contamination. Surfactants were used to enhance the solubilization and mobilization of DNAPL during the remediation process. In situ chemical oxidation (ISCO) was then used to deliver oxidants into the sub-surface to destroy organic contaminants in the soil and ground water. Experimental 2-D flow-through cell studies of 72 surfactants were conducted with the permanganate to evaluate delivery methods and determine compatible co-solvents for the surfactant process. Delivery methods included co-injection and sequential application. Four compatible surfactants were found to be compatible with the permanganate. A 90 percent DNAPL remediation rate was achieved using relatively low surfactant and oxidant concentrations. tabs., figs.

    In this work we present our most advanced technology node of organic thin film transistors (OTFTs) manufactured with a channel length as short as 2 μm by contact photolithography and a self-alignment process directly on a plastic substrate. Our process design kit (PDK) is described with P-type transistors, capacitors and 3 metal layers for connections of complex circuits. The OTFTs are composed of a double dielectric layer with a photopatternable ultra thin polymer (PNDPE) and alumina, with a thickness on the order of 100 nm. The organic semiconductor is either Pentacene or DNTT, which have a stable average mobility up to 0.1 cm2/Vs. Finally, a polymer (e.g.: Parylene-C) is used as a passivation layer. We describe also our design rules for the placement of standard circuit cells. A "plastic wafer" is fabricated containing 49 dies. Each die of 1 cm2 has between 25 to 50 devices, proving larger scale integration in such a small space, unique in organic technologies. Finally, we present the design (by simulations using a Spice model for OTFTs) and the test of analog and digital basic circuits: amplifiers with DC gains of about 20 dB, comparators, inverters and logic gates working in the frequency range of 1-10 kHz. These standard circuit cells could be used for signal conditioning and integrated as active matrices for flexible sensors from 3rd party institutions, thus opening our fab to new ideas and sophisticated pre-industrial low cost applications for the emerging fields of biomedical devices and wearable electronics for virtual/augmented reality.

  3. Presenting a Model Based on Fuzzy Application to Optimize the Time of IBS Projects in Gas Refineries

    Full Text Available Nowadays, the construction industry has started to embrace IBS as a method of attaining better construction quality and productivity and reducing risks related to occupational safety and health. The built of pre-fabricated component in factories reduces many problems related to lack of purposing uncertainty in scheduling calculation and time management of projects. In the case of using IBS method for managing time in projects, former studies such as Allan Tay’s research, indicates that this method can save up at least 29% of overall completion period versus the conventional method. But beside mentioned advantages of this technical method, the projects could be optimized more and more in scheduling calculations. This issue is critical in gas refineries, since special parameters such as risk of spreading poison H2S gas and mandatory of performing projects in short time period events such as maintenance overhauls demands to perform projects in optimum time. Custom scheduling calculation of project planning uses the Critical Path Method (CPM as a tool for Planning Project’s activities. The researches of this paper’s authors indicated that Fuzzy Critical Path Method (FCPM is the best technique to manage the uncertainty in project scheduling and can save up the construction project’s time versus the custom methods. This paper aims to present a model based on fuzzy application in CPM calculations to optimize the time of Industrial Building System.

  5. The benefits of paired-agent imaging in molecular-guided surgery: an update on methods and applications (Conference Presentation)

    Tichauer, Kenneth M.

    2016-03-01

    One of the major complications with conventional imaging-agent-based molecular imaging, particularly for cancer imaging, is variability in agent delivery and nonspecific retention in biological tissue. Such factors can account to "swamp" the signal arising from specifically bound imaging agent, which is presumably indicative of the concentration of targeted biomolecule. In the 1950s, Pressman et al. proposed a method of accounting for these delivery and retention effects by normalizing targeted antibody retention to the retention of a co-administered "untargeted"/control imaging agent [1]. Our group resurrected the approach within the last 5 years, finding ways to utilize this so-called "paired-agent" imaging approach to directly quantify biomolecule concentration in tissue (in vitro, ex vivo, and in vivo) [2]. These novel paired-agent imaging approaches capable of quantifying biomolecule concentration provide enormous potential for being adapted to and optimizing molecular-guided surgery, which has a principle goal of identifying distinct biological tissues (tumor, nerves, etc…) based on their distinct molecular environment. This presentation will cover the principles and nuances of paired-agent imaging, as well as the current status of the field and future applications. [1] D. Pressman, E. D. Day, and M.

    This study investigated the application of the self-generation effect to enhance the recognition and retention of Blissymbols in persons with severe aphasia. A 2×2×3 factorial design of two treatment types (self-generation and non-generation) was used to teach two sets of Blissymbols. These were administered during 3 training days, between which were withdrawal periods of 1 day and 7 days. Recognition and retention probes were administered at intervals during the training. ANOVA analysis showed that the self-generation treatment produced no immediate recognition advantage; however, better retention of symbol recognition may have occurred over time. Hence, the potential application of the self-generation effect in enhancing the retention of Blissymbols in persons with severe aphasia may warrant further investigation.

    2013-08-01

    Music therapy is the customised application of music for therapeutic use. For the treatment of depression it is mostly applied within a multimodal therapeutic approach. Since music was already used in prehistoric societies to cure diseases, it can be considered as a traditional therapy. As early as the antiquity physicians discussed the kind of music, the duration and frequency of its application. In the 19th century the pioneers of modern scientific psychiatry began to follow these questions with empirical experimental research. Since the 20th century, research has been investigating the influence of music on biological and psychological parameters. Current studies show that music therapy appears to improve symptoms of depression, especially in combination with antidepressants. Due to the limited number of randomised studies, the validity of its efficiency is limited. Further research is necessary to provide evidence-based recommendations regarding music therapy for the treatment of depression. © Georg Thieme Verlag KG Stuttgart · New York.

    Reviews have been made on the researches and developments for human models in the field of nuclear engineering. Until now, the related works have been made mainly for the modeling of plant operator and operator crew in the control room, but also there arise new tendencies of extending the modeling works for maintenance field as well as for personnel training purposes. The whole range of human model research is divided into the five areas of (a) modeling for machine system, (b) measurement and analysis of human information behavior, (c) modeling of human internal information process, (d) modeling of human interaction with machine system, and (e) that of between human themselves. The real examples of the human model developments as well as their methods, applications, and the model validations are described, and then, the further subjects and efforts are pointed out which would be needed for the broader industrial application of the human modeling.

    Chiral control of nonlinear optical functions holds a great promise for a wide range of applications including optical signal processing, bio-sensing and chiral bio-imaging. In chiral polyfluorene thin films, we demonstrated extremely large chiral nonlinearity. The physics of manipulating excitation dynamics for photon transformation will be discussed, along with nanochemistry control of upconversion in hierarchically built organic chromophore coupled-core-multiple shell nanostructures which enable introduce new, organic-inorganic energy transfer routes for broadband light harvesting and increased upconversion efficiency via multistep cascaded energy transfer. We are pursuing the applications of photon conversion technology in IR harvesting for photovoltaics, high contrast bioimaging, photoacoustic imaging, photodynamic therapy, and optogenetics. An important application is in Brain research and Neurophotonics for functional mapping and modulation of brain activities. Another new direction pursued is magnetic field control of light in in a chiral polymer nanocomposite to achieve large magneto-optic coefficient which can enable sensing of extremely weak magnetic field due to brain waves. Finally, we will consider the thought provoking concept of utilizing photons to quantify, through magneto-optics, and augment - through nanoptogenetics, the cognitive states, thus paving the path way to a quantified human paradigm.

    The mid-Infrared wavelength range (2-20 µm), so-called fingerprint region, contains the very sharp vibrational and rotational resonances of many chemical and biological substances. Thereby, on-chip absorption-spectrometry-based sensors operating in the mid-Infrared (mid-IR) have the potential to perform high-precision, label-free, real-time detection of multiple target molecules within a single sensor, which makes them an ideal technology for the implementation of lab-on-a-chip devices. Benefiting from the great development realized in the telecom field, silicon photonics is poised to deliver ultra-compact efficient and cost-effective devices fabricated at mass scale. In addition, Si is transparent up to 8 µm wavelength, making it an ideal material for the implementation of high-performance mid-IR photonic circuits. The silicon-on-insulator (SOI) technology, typically used in telecom applications, relies on silicon dioxide as bottom insulator. Unfortunately, silicon dioxide absorbs light beyond 3.6 µm, limiting the usability range of the SOI platform for the mid-IR. Silicon-on-sapphire (SOS) has been proposed as an alternative solution that extends the operability region up to 6 µm (sapphire absorption), while providing a high-index contrast. In this context, surface grating couplers have been proved as an efficient means of injecting and extracting light from mid-IR SOS circuits that obviate the need of cleaving sapphire. However, grating couplers typically have a reduced bandwidth, compared with facet coupling solutions such as inverse or sub-wavelength tapers. This feature limits their feasibility for absorption spectroscopy applications that may require monitoring wide wavelength ranges. Interestingly, sub-wavelength engineering can be used to substantially improve grating coupler bandwidth, as demonstrated in devices operating at telecom wavelengths. Here, we report on the development of fiber-to-chip interconnects to ZrF4 optical fibers and integrated SOS

    Nanotechnology has been developed for decades and many interesting optical properties have been demonstrated. However, the major hurdle for the further development of nanotechnology depends on finding economic ways to fabricate such nanostructures in large-scale. Here, we demonstrate how to achieve low-cost fabrication using nanosphere-related techniques, such as Nanosphere Lithography (NSL) and Nanospherical-Lens Lithography (NLL). NSL is a low-cost nano-fabrication technique that has the ability to fabricate nano-triangle arrays that cover a very large area. NLL is a very similar technique that uses polystyrene nanospheres to focus the incoming ultraviolet light and exposure the underlying photoresist (PR) layer. PR hole arrays form after developing. Metal nanodisk arrays can be fabricated following metal evaporation and lifting-off processes. Nanodisk or nano-ellipse arrays with various sizes and aspect ratios are routinely fabricated in our research group. We also demonstrate we can fabricate more complicated nanostructures, such as nanodisk oligomers, by combining several other key technologies such as angled exposure and deposition, we can modify these methods to obtain various metallic nanostructures. The metallic structures are of high fidelity and in large scale. The metallic nanostructures can be transformed into semiconductor nanostructures and be used in several green technology applications.

  20. Laser annealed in-situ P-doped Ge for on-chip laser source applications (Conference Presentation)

    Realization of a monolithically integrated on-chip laser source remains the holy-grail of Silicon Photonics. Germanium (Ge) is a promising semiconductor for lasing applications when highly doped with Phosphorous (P) and or alloyed with Sn [1, 2]. P doping makes Ge a pseudo-direct band gap material and the emitted wavelengths are compatible with fiber-optic communication applications. However, in-situ P doping with Ge2H6 precursor allows a maximum active P concentration of 6×1019 cm-3 [3]. Even with such active P levels, n++ Ge is still an indirect band gap material and could result in very high threshold current densities. In this work, we demonstrate P-doped Ge layers with active n-type doping beyond 1020 cm-3, grown using Ge2H6 and PH3 and subsequently laser annealed, targeting power-efficient on-chip laser sources. The use of Ge2H6 precursors during the growth of P-doped Ge increases the active P concentration level to a record fully activated concentration of 1.3×1020 cm-3 when laser annealed with a fluence of 1.2 J/cm2. The material stack consisted of 200 nm thick P-doped Ge grown on an annealed 1 µm Ge buffer on Si. Ge:P epitaxy was performed with PH3 and Ge2H6 at 320oC. Low temperature growth enable Ge:P epitaxy far from thermodynamic equilibrium, resulting in an enhanced incorporation of P atoms [3]. At such high active P concentration, the n++ Ge layer is expected to be a pseudo-direct band gap material. The photoluminescence (PL) intensities for layers with highest active P concentration show an enhancement of 18× when compared to undoped Ge grown on Si as shown in Fig. 1 and Fig. 2. The layers were optically pumped with a 640 nm laser and an incident intensity of 410 mW/cm2. The PL was measured with a NIR spectrometer with a Hamamatsu R5509-72 NIR photomultiplier tube detector whose detectivity drops at 1620 nm. Due to high active P concentration, we expect band gap narrowing phenomena to push the PL peak to wavelengths beyond the detection limit

    2001-01-01

    A number of reactor concepts are being advanced worldwide also in the light of long-term perspectives in the power economy. Activities in this respect are concentrated on the proven technologies of light-water and heavy-water reactors and on gas or liquid-metal cooled designs. Also smaller units are being considered for various applications. Framatome ANP focus on further development of the EPR and SWR 1000 light-water reactor lines. These plant concepts, which were developed in cooperation with, and with the support of, power utilities together with a number of European partners, are characterized by an even higher level of safety, especially as far as potential accidental releases are concerned, and by their competitiveness in the electricity generating market compared to other sources of energy. Given the cost structure of these plants, with approx. 60% capital costs, approx. 24% operating costs, and approx. 16% fuel cycle costs, efforts are made in particular to reduce the dominating capital cost share. For the EPR, this is to be achieved by high plant capacities, i.e. lower specific capital outlays per kilowatt installed; for the SWR 1000, mainly by means of an optimized, streamlined plant design. Moreover, installed nuclear generating capacities provide long-term assurance in calculating electricity generating costs, as they are less sensitive to the variable costs of the fuel cycle and of operation than fossil-fired plants. Commercial maturity of the SWR 1000 will be achieved after the completion of basic development in late 1999 and the ongoing detailed design steps in 2001. Also for the EPR, commercial maturity has been achieved with the completion of the basic design phase. (orig.) [de

  2. Structure-based thresholds of toxicological concern-guidance for application to substances present at low levels in the diet

    Health-based guidance values, such as the ADI, use chemical-specific data to determine the highest intake that would be without significant adverse health effects. A threshold of toxicological concern (TTC) is a level of intake predicted to be without adverse effects based on the toxicity of structurally related compounds. The main advantage of the use of TTCs is that the risk of low exposures can be evaluated without the need for chemical-specific animal toxicity data. TTCs have been used for many years for screening the safety of packaging migrants by the FDA in the USA, and of flavoring substances, by the JECFA. A recent reassessment of the use of TTCs, organized by ILSI Europe, has developed a decision tree which allows a systematic approach to the evaluation of low levels of diverse chemicals in food. The decision tree incorporates a series of increasing TTC values into a step-wise approach. Potentially genotoxic carcinogens are considered first, based on the presence of known structural alerts. Aflatoxin-like, azoxy- and nitroso-compounds are removed from consideration because they are the most potent, and a practical TTC could not be established. Other compounds with structural alerts for genotoxicity are allocated a TTC of 0.15 μg/person per day. Compounds without structural alerts for genotoxicity are evaluated based on chemical structure and intake using a series of TTC values derived by the application of a 100-fold uncertainty factor to the 5th percentile of the distribution of NOAELs from chronic studies on compounds sharing similar structural characteristics

    1999-01-01

    The inefficacy of conventional methods to destroy toxic organic compounds present in industrial effluent has taken the search for new technologies of treatment. he water irradiation is the most efficient process to generate radicals that mineralise these compounds. A study to evaluate the Advanced Oxidation Process by electron beam irradiation to treat industrial effluent with high toxic organic compounds concentration was carried out. Experiments were conducted using a Radiation Dynamics Electron Beam Accelerator with 1,5 MeV energy and 37 power. The effluent samples from a big industrial complex were irradiated using the IPEN's Liquid Effluent Irradiation Pilot Plant and the effluent samples from five steps of a Governmental Wastewater Treatment Plant from SABESP - ETE Suzano (industrial Receiver Unit, Coarse Bar Screens, Medium Bar Screens, Primary Sedimentation and Final Effluent), were irradiated in a batch system. The electron beam irradiation showed be efficient on destroying the organic compounds delivered in these effluents mainly chloroform, dichloroethane, methyl isobutyl ketone, benzene, toluene, xylene, phenol and in the decoloring of dyes present in some samples. To remove 90% of the most organic compounds was necessary a 20 kGy dose for industry's ETE, 20 kGy for IRU, CBS and MBS and 10 kGy to 20 kGy for PS and FE. (author)

    This study investigates the anticipated psychosocial impact of present web-based e-health services and future mobile health applications among older Swedes. Random sample's of Swedish citizens aged 55 years old and older were given a survey containing two different e-health scenarios which respondents rated according to their anticipated psychosocial impact by means of the PIADS instrument. Results consistently demonstrated the positive anticipation of psychosocial impacts for both scenarios. The future mobile health applications scored more positively than the present web-based e-health services. An increase in age correlated positively to lower impact scores. These findings indicate that from a psychosocial perspective, web-based e-health services and mobile health applications are likely to positively impact quality of life. This knowledge can be helpful when tailoring and implementing e-health services that are directed to older people.

    This paper is focused on the soft x-ray (SXR) tomography system setup at Tore Supra (DTOMOX) and the recent developments made to automatically get precise information about plasma features from inverted data. The first part describes the main aspects of the tomographic inversion optimization process. Several observations are made using this new tool and a set of shape factors is defined to help characterizing the emissivity field in a real-time perspective. The second part presents a detailed off-line analysis comparing the positions of the magnetic axis obtained from a magnetic equilibrium solver, and the maximum of the reconstructed emissivity field for ohmic and heated pulses. A systematic discrepancy of about 5 cm is found in both cases and it is shown that this discrepancy increases during sawtooth crashes. Finally, evidence of radially localized tungsten accumulation with an in-out asymmetry during a lower hybrid current drive pulse is provided to illustrate the DTOMOX capabilities for a precise observation of local phenomena.

    White biotechnology has made a positive impact on the chemical industry by providing safer, more efficient chemical manufacturing processes that have reduced the use of toxic chemicals, harsh reaction conditions, and expensive metal catalysts, which has improved alignment with the principles of Green Chemistry. The genetically-modified (GM) biocatalysts that are utilized in these processes are typically separated from high-value products and then recycled, or eliminated. Elimination routes include disposal in sanitary landfills, incineration, use as a fuel, animal feed, or reuse as an agricultural soil amendment or other value-added products. Elimination routes that have the potential to impact the food chain or environment have been more heavily scrutinized for the fate and persistence of biological products. In this study, we developed and optimized a method for monitoring the degradation of strain-specific DNA markers from a genetically-modified organism (GMO) used for the commercial production of 1,3-propanediol. Laboratory and field tests showed that a marker for heterologous DNA in the GM organism was no longer detectable by end-point polymerase chain reaction (PCR) after 14 days. The half-life of heterologous DNA was increased by 17% (from 42.4 to 49.7 h) after sterilization of the soil from a field plot, which indicated that abiotic factors were important in degradation of DNA under field conditions. There was no evidence for horizontal transfer of DNA target sequences from the GMO to viable organisms present in the soil.

    The 4-m International Liquid Mirror Telescope (ILMT) located at the ARIES Observatory (Devasthal, India) has been designed to scan at a latitude of +29° 22' 26" a band of sky having a width of about half a degree in the Time Delayed Integration (TDI) mode. Therefore, a special data-reduction and analysis pipeline to process online the large amount of optical data being produced has been dedicated to it. This requirement has led to the development of the 4-m ILMT data reduction pipeline, a new software package built with Python in order to simplify a large number of tasks aimed at the reduction of the acquired TDI images. This software provides astronomers with specially designed data reduction functions, astrometry and photometry calibration tools. In this paper we discuss the various reduction and calibration steps followed to reduce TDI images obtained in May 2015 with the Devasthal 1.3m telescope. We report here the detection and characterization of nine space debris present in the TDI frames.

    The aim of this study was to evaluate an infant oral health education programme, using a pre-post test design, for parents attending a paediatric clinic. The subjects were parents attending the well baby appointments at 3, 6, and 9 months of age. The study participants were men and women, all with an infant between 3 and 12 months of age. A 16 question assessment in the form of a questionnaire was completed immediately before and after the introduction of a 30 min educational intervention in the form of a PowerPoint presentation and a video of infant oral hygiene for parents. The parents completed the questionnaire twice (pre-post test design) in the same visit. Recruited parents attended only one presentation. The presentation educated parents about infant oral health and provided anticipatory guidance. Forty-seven parents or caretakers participated in the study. On the pre-test 28% had a score of 70% or less, and on the post-test 87% got a score of 88% or better. On the pre-test, 72% had a score of 70% or higher, and on the post-test 87% got a score of 88% or higher. Most parents (80%) reported that the presentation was helpful and indicated that the information would change the way they care for their baby's teeth at home. This study demonstrated the effectiveness of a 30 min PowerPoint and Video presentation in improving the oral health knowledge of parents caring for an infant.

  14. Moessbauer spectroscopy and transition metal chemistry. Fundamentals and applications

    2011-01-01

    Moessbauer spectroscopy is a profound analytical method which has nevertheless continued to develop. The authors now present a state-of-the art book which consists of two parts. The first part details the fundamentals of Moessbauer spectroscopy and is based on a book published in 1978 in the Springer series 'Inorganic Chemistry Concepts' by P. Guetlich, R. Link and A.X. Trautwein. The second part covers useful practical aspects of measurements, and the application of the techniques to many problems of materials characterization. The update includes the use of synchroton radiation and many instructive and illustrative examples in fields such as solid state chemistry, biology and physics, materials and the geosciences, as well as industrial applications. Special chapters on magnetic relaxation phenomena (S. Morup) and computation of hyperfine interaction parameters (F. Neese) are also included. An attached CD-ROM with more than 400 full-color PowerPoint images provides self-explanatory examples. The book concentrates on teaching the technique using theory as much as needed and as little as possible. The reader will learn the fundamentals of the technique and how to apply it to many problems of materials characterization. Transition metal chemistry, studied on the basis of the most widely used Moessbauer isotopes, is in the foreground. (orig.)

    Osteoarthritis (OA) is one of the leading diseases of the musculoskeletal system and the main cause of arthritic joint damage. The objective of the present study was to evaluate the effectiveness of the combined application of radon baths and shock-wave therapy in the patients suffering from knee OA. The study involved 75 patients at the age of 35 to 62 years with the confirmed diagnosis of stage II and III gonarthrosis; they were divided into 3 groups. The patients of the main group received the combined treatment including extracorporeal shock-wave therapy and radon baths The patients comprising the group of comparison were given the course of radon therapy alone while those in the control group were offered the standard treatment including physiotherapy, magnetic therapy, and NSAIDs. The study has demonstrated the high effectiveness of the combined application of the radon baths and extracorporeal shock-wave therapy for the rehabilitation of the patients with deforming arthrosis of the knee that was apparent from the substantial decrease of pain syndrome, the increase of the range of motions in the knee joints, and the overall improvement of the quality of life. These beneficial changes persisted for a period of up to 6 months. The results of the present study give reason to recommend the proposed method of the remedial treatment for the wide practical application as a component in the framework of the medical rehabilitation programs.

  17. The craft of scientific presentations critical steps to succeed and critical errors to avoid

    CERN Document Server

    Alley, Michael

    2013-01-01

    The Craft of Scientific Presentations, 2nd edition aims to strengthen you as a presenter of science and engineering. The book does so by identifying what makes excellent presenters such as Brian Cox, Jane Goodall, Richard Feynman, and Jill Bolte Taylor so strong. In addition, the book explains what causes so many scientific presentations to flounder. One of the most valuable contributions of this text is that it teaches the assertion-evidence approach to scientific presentations. Instead of building presentations, as most engineers and scientists do, on the weak foundation of topic phrases and bulleted lists, this assertion-evidence approach calls for building presentations on succinct message assertions supported by visual evidence. Unlike the commonly followed topic-subtopic approach that PowerPoint leads presenters to use, the assertion-evidence approach is solidly grounded in research. By showing the differences between strong and weak presentations, by identifying the errors that scientific presenters ty...

    Melnikova, E A

    2015-01-01

    In this article, the results of the authors' research, including analysis of the clinical and instrumental data concerning 203 patients with, stroke are presented. It is shown that the clinical effectiveness of the transcranial methods incorporated in the combined rehabilitation programs depends on the type of stroke and localization of the lesions. Specifically, the patients presenting with ischemic stroke of hemispheric localization experienced a neurophysiologically confirmed significant clinical improvement that became apparent after the consistent application of transcranial magnetic therapy and micropolarization. In the patients with ischemic stroke of stem localization, the positive influence on psychomotor recovery was achieved with the application of transcranial magnetic therapy, but transcranial micropolarization did not have an appreciable effect on the recovery of such patients. The patients presenting with hemorrhagic stroke did not experience any significant improvement of psychomotor parameters from transcranial magnetic therapy and transcranial micropolarization. The likely mechanism underlying the recovery of psychomotor processes under effect of transcranial magnetic therapy in the patients with ischemic stroke is the normalization of the frequency of interaction between brain structures. In addition, in the patients with ischemic stroke of hemispheric localization and in the patients with hemorrhagic stroke electrical myostimulation has a marked impact on the psychomotor recovery only in case of functional treatment. In the patients suffering from ischemic stroke of stem localization non-functional electromyostimulation significantly improves motor functions and cognitive motor control.

    An important part of the workshop was a series of invited presentations. The presentations were intended to both provide the participants with an understanding of various organisational approaches and activities as well as to stimulate the exchange of ideas during the small group discussion sessions. The presentation subjects ranged from current organisational regulations and licensee activities to new organisational research and the benefits of viewing organisations from a different perspective. There were more than a dozen invited presentations. The initial set of presentations gave the participants an overview of the background, structure, and aims of the workshop. This included a short presentation on the results from the regulatory responses to the pre-workshop survey.

    Full Text Available During his time as a state senator in Illinois, Barack Obama voted “Present” 129 times, a deliberate act of nonvoting that subsequently became an important campaign issue during the 2008 presidential elections. In this article, I examine the use of Present votes in the Illinois state senate. I find evidence that Present votes can largely be characterized as protest votes used as a legislative tool by the minority party. Incorporating information from Present votes into a Bayesian polytomous item-response model, I find that this information increases the efficiency of ideal point estimates by approximately 35%. There is little evidence of significant moderation by Obama when Present votes are accounted for, though my results suggest that Obama’s voting record may have moderated significantly before his subsequent election to the U.S. Senate. My results also suggest that because legislative nonvoting may occur for a variety of reasons, naive inclusion of nonvoting behavior into vote choice models may lead to biased results.

    The report presents a wide, easily understandable description of presentation technique and man-machine communication. General fundamentals for the man-machine interface are illustrated, and the factors that affect the interface are described. A model is presented for describing the operators work situation, based on three different levels in the operators behaviour. The operator reacts routinely in the face of simple, known problems, and reacts in accordance with predetermined plans in the face of more complex, recognizable problems. Deep fundamental knowledge is necessary for truly complex questions. Today's technical status and future development have been studied. In the future, the operator interface will be based on standard software. Functions such as zooming, integration of video pictures, and sound reproduction will become common. Video walls may be expected to come into use in situations in which several persons simultaneously need access to the same information. A summary of the fundamental rules for the design of good picture ergonomics and design requirements for control rooms are included in the report. In conclusion, the report describes a presentation technique within the Distribution Automation and Demand Side Management area and analyses the know-how requirements within Vattenfall. If different systems are integrated, such as geographical information systems and operation monitoring systems, strict demands are made on the expertise of the users for achieving a user-friendly technique which is matched to the needs of the human being.

    The wide spread of digital technology in the medical field has led to a demand for the high-quality, high-speed, and user-friendly digital image presentation system in the daily medical conferences. To fulfill this demand, we developed a presentation system for radiological and pathological images. It is composed of a super-high-definition (SHD) imaging system, a radiological image database (R-DB), a pathological image database (P-DB), and the network interconnecting these three. The R-DB consists of a 270GB RAID, a database server workstation, and a film digitizer. The P-DB includes an optical microscope, a four-million-pixel digital camera, a 90GB RAID, and a database server workstation. A 100Mbps Ethernet LAN interconnects all the sub-systems. The Web-based system operation software was developed for easy operation. We installed the whole system in NTT East Kanto Hospital to evaluate it in the weekly case conferences. The SHD system could display digital full-color images of 2048 x 2048 pixels on a 28-inch CRT monitor. The doctors evaluated the image quality and size, and found them applicable to the actual medical diagnosis. They also appreciated short image switching time that contributed to smooth presentation. Thus, we confirmed that its characteristics met the requirements.

    Full Text Available The determination of the specific environment is important for the formulation of efficient enterprise strategies, on the basis of a strategic analysis properly focused. This paper suggests a method to help its limitation and identification. With its use, it pretends to offer a simple and practical tool that allows to have a more accurate approach to the identification of the industry that will be analysed, as well as, a clarification of the specification of the direct and substitute competition. Also, with the use of this tool, the managers of a business idea, an experienced or new organization, will have an approximation to the mentioned themes that are of a strategic importance in any management type. Likewise, two applications of the proposed method are presented: the first orientated to a business idea and the second to supermarkets with a high service charge in Lima, Peru.

    In Experiment 1, students received an illustrated booklet, PowerPoint presentation, or narrated animation that explained 6 steps in how a cold virus infects the human body. The material included 6 high-interest details mainly about the role of viruses in sex or death (high group) or 6 low-interest details consisting of facts and health tips about viruses (low group). The low group outperformed the high group across all 3 media on a subsequent test of problem-solving transfer (d = .80) but not retention (d = .05). In Experiment 2, students who studied a PowerPoint lesson explaining the steps in how digestion works performed better on a problem-solving transfer test if the lesson contained 7 low-interest details rather than 7 high-interest details (d = .86), but the groups did not differ on retention (d = .26). In both experiments, as the interestingness of details was increased, student understanding decreased (as measured by transfer). Results are consistent with a cognitive theory of multimedia learning, in which highly interesting details sap processing capacity away from deeper cognitive processing of the core material during learning.

    In the field of R and D programs of a geological disposal of high level radioactive waste, it is great importance to develop a set of investigation and analysis techniques for the assessment of long-term geosphere stability over a geological time, which means that any changes of geological environment will not significantly impact on the long-term safety of a geological disposal system. In Japanese archipelago, crustal movements are so active that uplift and subsidence are remarkable in recent several hundreds of thousands of years. Therefore, it is necessary to assess the long-term geosphere stability taking into account a topographic change caused by crustal movements. One of the factors for the topographic change is the movement of an active fault, which is a geological process to release a strain accumulated by plate motion. A beginning age of the faulting in the present faulting pattern suggests the beginning age of neotectonic activities around the active fault, and also provides basic information to identifying the stage of a geomorphic development of mountains. Therefore, the age of faulting in the present faulting pattern is important information to estimate a topographic change in the future on the mountain regions of Japan. In this study, existing information related to methods for the estimation of the beginning age of the faulting in the present faulting pattern on the active fault were collected and reviewed. A principle of method, noticing points and technical know-hows in the application of the methods, data uncertainty, and so on were extracted from the existing information. Based on these extracted information, task-flows indicating working process on the estimation of the beginning age for the faulting of the active fault were illustrated on each method. Additionally, the distribution map of the beginning age with accuracy of faulting in the present faulting pattern on the active fault was illustrated. (author)

    The objective of the present study was the improvement of the effectiveness of medical rehabilitation of the children presenting with the disturbances of the locomotor function using a «LymphaVision» apparatus for the selective electrical stimulation. The study included 42 patients with movement disorders divided into two groups depending on the method of non-drug therapy. The main group was comprised of the patients receiving the treatment by electrical stimulation with the use of the «LymphaVision» apparatus while the remaining patients made up the group of comparison (they were treated with by means of Vermel electrophoresis with the use of a 1% sodium bromide solution). The increase of the muscular strength evaluated based on the scoring system and the number of motor skills were used as the criteria of the effectiveness of the treatment. The applied Statistica for Windows package, version 6.0 («StatSoft», USA). Was employed for the statistical analysis of the data obtained. The significance and number of differences between two independent samples of the quantitative features were assessed using the Mann-Whitney U test. The Wilcoxon matched pairs test was used to compare the two matched groups. The children comprising the group treated by means of selective exposure to electrical stimulation with the use of the «LymphaVision» apparatus in the course of the rehabilitation process exhibited a significant increase in the strength of the muscles of the lower extremities and the trunk over the baseline values (p=0.003 and p=0.04 respectively) and acquired a significantly greater number of the new motor skills (p=0.02). The application of the proposed method is characterized by the highly pronounced clinical efficiency. This approach is pathogenetically well-substantiated for the treatment of the children presenting with the locomotor disorders developing as the consequences of perinatal lesions in the central nervous system and promotes the restoration of

    The presentation topic is California's approach to license application review in meeting financial assurances for the proposed Ward Valley site. The purpose of the presentation is to provide information on specific financial assurance provisions contained in 10 CFR Part 61 and how California intends to satisfy those requirements. Also, as rate setter, California intends to demonstrate how it will assure allowable costs to the rate base though a financial prudency review. The key provisions of financial assurance are: 10 CFR Section 61.61 - This provision requires an applicant to demonstrate its ability to finance licensed activities; 10 CFR Section 61.62 - This provision requires an applicant to provide assurance that sufficient funds will be available for site closure and stabilization; and 10 CFR Section 61.63 - This provision requires an applicant to provide 'a copy of a binding arrangement, such as a lease, between the applicant and the disposal site owner, so that sufficient funds will be available to cover the costs of the institutional control period.' To assist California in its determination of financial assurance compliance to be demonstrated by the applicant for Part 61 requirements, is NUREG guidance document 1199 'Standard Format and Content of a License Application for a Low-Level Radioactive Waste (LLRW) Disposal Facility.' The detailed financial assurance provisions of NUREG 1199 are then embodied in NUREG 1200, 'Standard Review Plant for the Review of a License Application for a LLRW Disposal Facility.'

  1. Design of pulsed perforated-plate columns for industrial scale mass transfer applications - present experience and the need for a model based approach

    International Nuclear Information System (INIS)

    Roy, Amitava

    2010-01-01

    Mass transfer is a vital unit operation in the processing of spent nuclear fuel in the backend of closed fuel cycle and Pulsed perforated plate extraction columns are used as mass transfer device for more than five decades. The pulsed perforated plate column is an agitated differential contactor, which has wide applicability due to its simplicity, high mass transfer efficiency, high through put, suitability for maintenance free remote operation, ease of cleaning/decontamination and cost effectiveness. Design of pulsed columns are based on a model proposed to describe the hydrodynamics and mass transfer. In equilibrium stage model, the HETS values are obtained from pilot plant experiments and then scaled empirically to design columns for industrial application. The dispersion model accounts for mass transfer kinetics and back-mixing. The drop population balance model can describe complex hydrodynamics of dispersed phase, that is, drop formation, break-up and drop-to-drop interactions. In recent years, significant progress has been made to model pulsed columns using CFD, which provides complete mathematical description of hydrodynamics in terms of spatial distribution of flow fields and 3D visualization. Under the condition of pulsation, the poly-dispersed nature of turbulent droplet swarm renders modeling difficult. In the absence of industry acceptance of proposed models, the conventional chemical engineering practice is to use HETS-NTS concept or HTU-NTU approach to design extraction columns. The practicability of HTU-NTU approach has some limitations due to the lack of experimental data on individual film mass transfer coefficients. Presently, the HETS-NTS concept has been used for designing the columns, which has given satisfactory performance. The design objective is mainly to arrive at the diameter and height of the mass transfer section for a specific plate geometry, fluid properties and pulsing condition to meet the intended throughput (capacity) and mass

    Spasticity is considered to be a common manifestation of multiple sclerosis. Muscle relaxants are not sufficiently effective; more than that, some of them often cause a variety of adverse reactions. Transcranial magnetic stimulation (TMS) can be a promising new tool for the treatment of spasticity. The objective of the present study was to compare the effectiveness of the two TMS protocols: rhythmic (high-frequency) TMS (rTMS) and stimulation with the theta bursts (iTBS) in terms of their ability to reduce spasticity in the patients presenting with multiple sclerosis. Twenty two patients with secondary-progressive multiple sclerosis were pseudo-randomized into two groups: those in the first (high-frequency) group received the treatment with the use of rTMS therapy at a frequency of 10 Hz; the patients of the second group, underwent stimulation with the theta bursts (iTBS). All the patients received 10 sessions of either stimulation applied to the primary motor area (M1) of both legs. The effectiveness of TMS protocols was evaluated before therapy and after 10 sessions of stimulation based on the Modified Ashworth scale (MAS), the expanded disability status scale (EDSS), and the Kurtzke functional scale (Kfs). In addition, the patients were interviewed before treatment, after 10 rTMS sessions, immediately after and within 2 and 12 weeks after the completion of the treatment using questionnaires for the evaluation of spasticity (SESS) , fatigue, and dysfunction of the pelvic organs (severity of defecation and urination disorders), fatigue. The study has demonstrated a significant reduction in spasticity in the patients of both groups at the end of the TMS protocol based on the MAS scale. There was no significant difference between the outcomes of the two protocols. Both had positive effect on the concomitant «non-motor» symptoms (fatigue, dysfunction of the pelvic organs).

    Full Text Available The making of presentations has become an omnipresent act of communication in the companies practice, but also in the didactic one. The notoriety and the increase of the importance of an efficient presentation lie in the transformations felt by a society of knowledge, communication being the answer in front of a constant information wave.Business people look in fear at the preparation of a presentation, the interaction with the audience andtheir feedback, all these leading to a low efficiency in transmitting the message.The speaker must overcome a group of obstacles, the most important being the reduced human capacityto capture the information transmitted orally; in this respect, he has available a group of visual instruments and strategies to capture the attention. In order to achieve efficiency one needs mental and emotional preparation, knowing the audience and the presentation’s objective and eliminating the old listing format in PowerPoint, for focusing the communication of the audience’s necessities. The present essay aims to analyze the verbal, non-verbal and para-verbal communication act that constitutes the base of any presentation, the reasons that lead to failure and the ways to increase efficiency, in order to succeed in transmitting a well structured and easy to remember message.Many researchers and practice workers within the communication, economic but also IT fields, have tried to find the solution for organizing and transmitting the message during a presentation, in accordance with the new technologies. In elaborating the present paper, we have used our personal experience and data obtained through 30 in-depth interviews,with managers in companies such Bostina Asociatii Skoda, Petrom etc.; we have used in our research articles of honored professors in social sciences from the Harvard and Stanford Universities , researches of the Minnesota and Ulster Universities, as well as works of specialists in marketing and information

    This article describes a graduate class in presentation skills ("PClass") as a model for how a class with similar objectives, expectations and culture might be mounted for undergraduates. The required class is given for students in neuroscience and physiology programs at the University of North Carolina at Chapel Hill; I describe the class in the years I led it, from 2003-2012. The class structure centered on peer rehearsal, critiquing of PowerPoint, and chalk talks by the students; video-recording of student talks for later review by the student with the instructor; and presentation of polished talks in a formal setting. A different faculty visitor to the class each week gave the students a variety of perspectives. The students also gained insight into their own evolving skills by discussing the strengths and weaknesses of seminars given by visitors to the campus. A unique feature of the class was collaboration with a professional actor from the University's Department of Dramatic Arts, who helped the students develop techniques for keeping the attention of an audience, for speaking with confidence, and for controlling nervousness. The undergraduate campus would be expected to lend itself to this sort of interdisciplinary faculty cooperation. In addition, students worked on becoming adept at designing and presenting posters, introducing speakers graciously and taking charge of the speaker's question session, and speaking to a lay audience.

But does that technique generate useful information to the audience? Or if speaking to a lay audience, does that kind of talk make the audience members get out their cell phones and call the office to make an appointment in our practice? Probably not. This article will provide suggestions that will enhance your speaking and presentation skills. This, in turn, will make you a darling of the pharma industry and encourage potential patients in your audience to become patients in your practice.

    The position in the research field of radiation application of Theoretical Analysis Group for Radiation Application' which will be set up within fiscal 2003, and the relation between the research that this analytical group will advance in future and the analytical research made so far at Takasaki Radiation Chemistry Establishment (JAERI, Takasaki) are summarized. Since the JAERI Takasaki was founded as the center of the research and development on radiation chemistry, a lot of outcomes have been obtained in the research and development of radiation application using large-sized {sup 60}Co gamma ray irradiation facilities and high power electron accelerators, etc. After the ion irradiation research facility (TIARA) started operation, many outstanding outcomes have been obtained in the research of up-to-date science and technologies in the fields of material science and bio-technology, etc., making use of ions in addition to gamma rays and electron beams. Although these results of the research are mainly produced experimentally, theoretical analyses also are thought to be important because these results will be applied and expanded in future. We aim to set up 'Theoretical Analysis Group for Radiation Application' in fiscal 2003, and we aim at performing theoretical and engineering analyses about phenomena and things such as radiation chemical reactions, irradiation/implantation effects to semiconductors, model for plant function, etc. The irradiation effects of charged particles to materials are divided into the primary effects like generation of radicals and lattice defects, etc., which occurs immediately after charged particles impinge on materials, and the secondary effects like chemical changes and physical changes caused in materials as a result of the primary effects. The subjects of our analytical research are the analyses of the secondary effects and the systems which utilize the chemical and the physical changes to the radiation application

     In Japan, a pharmacy or drug store license is required for selling pharmaceutical products. However, civilians without a pharmacy or drug store license are displaying pharmaceutical products for sale on a flea market application, which is illegal dealing. This study discussed the modality for implementing countermeasures for the illicit selling of pharmaceutical products. We extracted pharmaceutical products displayed for sale on three flea market applications (Mercari, Rakuma, Fril) on one day. One hundred and eighty-one pharmaceutical products were displayed (49 on Mercari, 86 on Rakuma, and 46 on Fril). There were 6.1% (11/181) domestically prescribed drugs, 69.1% (125/181) domestic OTC drugs, 23.8% (43/181) foreign-made prescribed drugs, and 1.1% (2/181) foreign-made OTC drugs. The seller could display the product for sale without confirming whether it is prohibited. We alerted the service providers of this illicit selling at flea markets at three different instances. The pharmaceutical product displays were deleted by the service providers at a rate of 55.1% (27/49) for Mercari and 51.2% (44/86) for Rakuma. The average number of drugs that were displayed for sale by each seller was 1.4 and the average number of total products that were displayed for sale by each seller was 100. The seller could have unintentionally displayed the pharmaceutical products for sale, without the knowledge that it is illegal. The service providers of flea market applications should create mechanisms to alert the sellers that displaying pharmaceutical products for sale is an illicit act and regulate these violations.

    2016-03-01

    In the last few years Multiphoton Excitation Microscopy witnessed a mutation from tool for imaging cellular structures in living animals deeper than other high-resolution techniques, into an instrument for monitoring functionality and even stimulating or inhibiting inter-cellular signalling. This paradigm shift has been enabled primarily by the development of genetically encoded probes like Ca indicators (GECI) and Opsins for optogenetics inhibition and stimulation. These developments will hopefully enable the understanding of how local network of hundreds or thousands of neurons operate in response to actual tasks or induced stimuli. Imaging, monitoring signals and activating neurons, all on a millisecond time scale, requires new laser tools providing a combination of wavelengths, higher powers and operating regimes different from the ones traditionally used for classic multiphoton imaging. The other key development in multiphoton techniques relates to potential diagnostic and clinical applications where non-linear imaging could provide all optical marker-free replacement of H and E techniques and even intra-operative guidance for procedures like cancer surgery. These developments will eventually drive the development of specialized laser sources where compact size, ease of use, beam delivery and cost are primary concerns. In this talk we will discuss recent laser product developments targeting the various applications of multiphoton imaging, as fiber lasers and other new type of lasers gradually gain popularity and their own space, side-by-side or as an alternative to conventional titanium sapphire femtosecond lasers.

    Full Text Available Investigation of the processes of channel sedimentation in riverbeds of lowland rivers has important fundamental and practical importance. In the economic development of river valleys a lot of attention is paid to the dynamics of the major reliefforming processes within the floodplain. A typical example showing the pattern of forming landforms and type of floodplain processes is deposition and redeposition of riverine sediment. In the future sedimentation of alluvium in areas of riverine floodplain makes the growth rate of natural levees, islands and shoals. For the average flow of the Oka river the pace of modern dynamics of accumulation of alluvium in the riverine areas is clarified. For the first time in this area the method of mat traps is applied. Rubber and coconut fiber were selected as the main materials for the traps. Specific features of the application methods and the difficulties encountered in its application were defined. The authors obtained the data about thickness of the layer of sediment accumulation of river flood of 2015, the results of particle size analysis of alluvial material with traps. The main patterns of distribution of fractions of alluvium and the pace of accumulation of various forms of riverine floodplain accumulation were identified. Tested methodology has proven its effectiveness and was found promising for use in the future in this region.

    The relevance of the problem of rheumatoid arthritis arises from the influence of such factors as its prevalence rate, unpredictability, tendency towards the transition to the chronic form, severe pain syndrome, high levels of disability, and long-term loss of working ability, as well as the accompanying psycho-emotional disorders. The present reviews article was designed to analyze the premorbid personality characteristics, the specifics features of mental health, and the response to the disease in the patients presenting with rheumatoid arthritis. Special emphasis is placed on the discusses of the relationship between the intensity of the pain syndrome and psycho-emotional disorders. The factors responsible for the development of the depressive states associated with rheumatoid arthritis are distinguished; they are shown to be related to both pathogenesis and the clinical symptoms of the underlying pathology as well as the general course of the disease and the specific features of the patients' psychological condition. The most extensively applied psychodiagnostics techniques are described, and the commonest psychotherapeutic approaches to the combined therapy and rehabilitation of the patients presenting with rheumatoid arthritis are overviewed.

    The understanding of factors affecting pesticide transfers to catchment outlet is still at a very early stage in tropical context, and especially on tropical volcanic context. We performed on-farm pesticide use surveys during 87 weeks and monitored pesticides in water weekly during 67 weeks at the outlet of a small catchment in Martinique. We identified three types of pollution. First, we showed long-term chronic pollution by chlordecone, diuron and metolachlor resulting from horticultural practices applied 5-20 years ago (quantification frequency higher than 80%). Second, we showed peak pollution. High amounts of propiconazole and fosthiazate applied at low frequencies caused river pollution peaks for weeks following a single application. Low amounts of diquat and diazinon applied at low frequencies also caused pollution peaks. The high amounts of glyphosate applied at high frequency resulted into pollution peaks by glyphosate and aminomethylphosphonic acid (AMPA) in 6 and 20% of the weeks. Any intensification of their uses will result in higher pollution levels. Third, relatively low amounts of glufosinate-ammonium, difenoconazol, spinosad and metaldehyde were applied at high frequencies. Unexpectedly, such pesticides remained barely detected (pollution of shallow aquifers alimenting surface water. We prove that to avoid the past errors and decrease the risk of long-term pollution of water resources, it is urgent to reduce or stop the use of pesticides with leaching potential by changing agricultural practices.

    The biological and technological characteristics of kefiran as well as its importance in grain integrity led us to analyze the microbial kefir grain consortium with focus on Lactobacillus kefiranofaciens. The presence of L. kefiranofaciens in the nine kefir grains studied was demonstrated by denaturing gradient gel electrophoresis. By culture dependent methods applying a methodology focused on the search of this species, 22 isolates with typical morphology were obtained and identified applying a combination of SDS-PAGE of whole cell proteins, (GTG)5-PCR and sequence analysis of the housekeeping gene encoding the α-subunit of bacterial phenylalanyl-tRNA synthase (pheS). This polyphasic approach allowed the reliable identification of 11 L. kefiranofaciens, 5 Lactobacillus paracasei, 4 Lactobacillus kefiri and 2 Lactobacillus parakefiri isolates. Isolated L. kefiranofaciens strains produced polysaccharide in strain-dependent concentrations and EPS produced by them also differed in the degree of polymerization. The isolation and accurate identification of L. kefiranofaciens is relevant taking into account the important role of this microorganism in the grain ecosystem as well as its potential application as starter in food fermentations.

    Quantum cascade (QC) lasers opens new prospects for powerful sources operating at THz frequencies. Up to now the best THz QC lasers are based on intersubband emission in GaAs/AlGaAs quantum well (QW) heterostructures. The maximum operating temperature is 200 K, which is too low for wide-spread applications. This is due to the rather low LO-phonon energy (36 meV) of GaAs-based materials. Indeed, thermal activation allows non-radiative path through electron-phonon interaction which destroys the population inversion. Wide band gap materials such as ZnO have been predicted to provide much higher operating temperatures because of the high value of their LO-phonon energy. However, despite some observations of intersubband absorption in c-plane ZnO/ZnMgO quantum wells, little is known on the fundamental parameters such as the conduction band offset in such heterostructures. In addition the internal field inherent to c-plane grown heterostuctures is an handicap for the design of QC lasers and detectors. In this talk, we will review a systematic investigation of ZnO/ZnMgO QW heterostructures with various Mg content and QW thicknesses grown by plasma molecular beam epitaxy on low-defect m-plane ZnO substrates. We will show that most samples exhibit TM-polarized intersubband absorption at room temperature linked either to bound-to-quasi bound inter-miniband absorption or to bound-to bound intersubband absorption depending on the Mg content of the barrier material. This systematic study allows for the first time to estimate the conduction band offset of ZnO/ZnMgO heterostructures, opening prospects for the design of QC devices operating at THz frequencies. This was supported by the European Union's Horizon 2020 research and innovation programme under grant agreement #665107.

  5. Application of fMRI to obesity research: differences in reward pathway activation measured with fMRI BOLD during visual presentation of high and low calorie foods

    The factors behind the neural mechanisms that motivate food choice and obesity are not well known. Furthermore, it is not known when these neural mechanisms develop and how they are influenced by both genetic and environmental factors. This study uses fMRI together with clinical data to shed light on the aforementioned questions by investigating how appetite-related activation in the brain changes with low versus high caloric foods in pre-pubescent girls. Previous studies have shown that obese adults have less striatal D2 receptors and thus reduced Dopamine (DA) signaling leading to the reward-deficit theory of obesity. However, overeating in itself reduces D2 receptor density, D2 sensitivity and thus reward sensitivity. The results of this study will show how early these neural mechanisms develop and what effect the drastic endocrinological changes during puberty has on these mechanisms. Our preliminary results showed increased activations in the Putamen, Insula, Thalamus and Hippocampus when looking at activations where High Calorie > Low Calorie. When comparing High Calorie > Control and Low Calorie > Control, the High > Control test showed increased significant activation in the frontal lobe. The Low > Control also yielded significant activation in the Left and Right Fusiform Gyrus, which did not appear in the High > Control test. These results indicate that the reward pathway activations previously shown in post-puberty and adults are present in pre-pubescent teens. These results may suggest that some of the preferential neural mechanisms of reward are already present pre-puberty.

    Surface addressable Photonic Crystal Membranes (PCM) are 1D or 2D photonic crystals formed in a slab waveguides where Bloch modes located above the light line are exploited. These modes are responsible for resonances in the reflection spectrum whose bandwidth can be adjusted at will. These resonances result from the coupling between a guided mode of the membrane and a free-space mode through the pattern of the photonic crystal. If broadband, these structures represent an ideal mirror to form compact vertical microcavity with 3D confinement of photons and polarization selectivity. Among numerous devices, low threshold VCSELs with remarkable and tunable modal properties have been demonstrated. Narrow band PCMs (or high Q resonators) have also been extensively used for surface addressable optoelectronic devices where an active material is embedded into the membrane, leading to the demonstration of low threshold surface emitting lasers, nonlinear bistables, optical traps... In this presentation, we will describe the main physical rules which govern the lifetime of photons in these resonant modes. More specifically, it will be emphasized that the Q factor of the PCM is determined, to the first order, by the integral overlap between the electromagnetic field distributions of the guided and free space modes and of the dielectric periodic perturbation which is applied to the homogeneous membrane to get the photonic crystal. It turns out that the symmetries of these distributions are of prime importance for the strength of the resonance. It will be shown that, by molding in-plane or vertical symmetries of Bloch modes, spectrally and spatially selective light absorbers or emitters can be designed. First proof of concept devices will be also presented.

    In this work, we have studied the bagasse from sugarcane as an alternative bioadsorbent in the treatment to oils and greases contaminated waters. The synthetic effluent was simulated by a distilled water and decahydronaphthalene dispersion, with initial concentration of 8900 mg . L {sup -1}. Gas chromatography was the analytical operation chosen to quantify the oil residual after the adsorption. The biomass was characterized by moisture analysis, CHNS and SEM. The experiments were carried out in batch process with agitation of 120 rpm, evaluating the equilibrium time of adsorptive process and the influence of pH of aqueous level. Results showed that the adsorption process achieved equilibrium quickly, in just 5 minutes of contact between the dispersion and biomass. No significant influence was noticed in the removal of hydrocarbon with the change in pH. The adsorption isotherm was developed changing by the mass of bioadsorbent, at 25 deg C, pH 6 and 120 rpm of agitation. The experimental results were fitted by Langmuir and Langmuir- Freundlich models. The best fit was obtained with Langmuir-Freundlich, providing a maximum adsorption capacity of 6,65 g hydrocarbon / g biomass. The experiments showed the great potential of the sugarcane bagasse to be used as bioadsorbent in reducing the oil and grease levels in industrial effluents. This alternative presents itself as a sustainable route due to the abundance of sugar cane bagasse in the sugar and alcohol industry, avoided the impact of aqueous sources contamination coming from oil and petrochemical industry.

    The ability to accurately predict power delivery over the course of time is of vital importance to the growth of the photovoltaic (PV) industry. Two key cost drivers are the efficiency with which sunlight is converted into power and secondly how this relationship develops over time. The accurate knowledge of power decline over time, also known as degradation rates, is essential and important to all stakeholders?utility companies, integrators, investors, and scientist alike. Outdoor testing plays a vital part in quantifying degradation rates of different technologies in various climates. Due to seasonal changes, however, several complete cycles (typically 3-5 years) need to be completed traditionally to obtain reasonably accurate degradation rates. In a rapidly evolving industry such a time span is often unacceptable and the need exists to determine degradation rates more accurately in a shorter period of time. Advanced time series modeling such as ARIMA (Autoregressive Integrated Moving Average) modeling can be utilized to decrease the required time span and is compared with some non-linear modeling. In addition, it will be demonstrated how the JMP 9 map feature was used to reveal important technological trends by climate.

  13. Multitasking simulation: Present application and future directions.

    Adams, Traci Nicole; Rho, Jason C

    2017-02-01

    The Accreditation Council for Graduate Medical Education lists multi-tasking as a core competency in several medical specialties due to increasing demands on providers to manage the care of multiple patients simultaneously. Trainees often learn multitasking on the job without any formal curriculum, leading to high error rates. Multitasking simulation training has demonstrated success in reducing error rates among trainees. Studies of multitasking simulation demonstrate that this type of simulation is feasible, does not hinder the acquisition of procedural skill, and leads to better performance during subsequent periods of multitasking. Although some healthcare agencies have discouraged multitasking due to higher error rates among multitasking providers, it cannot be eliminated entirely in settings such as the emergency department in which providers care for more than one patient simultaneously. Simulation can help trainees to identify situations in which multitasking is inappropriate, while preparing them for situations in which multitasking is inevitable.

  18. Making your presentation fun: creative presentation techniques

    What possesses someone to volunteer and go through hoops and red tape to make a presentation at a conference? For that matter, why does anyone ever present anything to anyone? Actually, presentations are a fact of life and there are many reasons for doing a presentation and doing it well. New and existing staff need training and orientation to the way things are done here. Handing all of them a manual and hoping they read it is pretty much a waste of paper. On the other hand, an effective, entertaining and upbeat presentation on the relevant topics is more likely to stick with those people. They will even have a name and face to remember and seek out when they have an issue on or with that topic. This can be a very effective beginning for networking with new peers. The presenter is seen as knowledgeable, as a source of information on company topics and possibly evaluated as a potential mentor or future manager. Project staff and/or peers benefit from clear, concise, presentations of topical knowledge. This is one way that a group working on various aspects of the same project or program can stay in touch and in step with each other. Most importantly, presentations may be the best or only door into the minds (and budgets) of management and customers. These presentations are a wonderful opportunity to address legal and compliance issues, budget, staffing, and services. Here is a chance, maybe the only one, to demonstrate and explain the wonderfulness of a program and the benefit they get by using the services offered most effectively. An interactive presentation on legal and compliance issues can be an effective tool in helping customers and/or management make good risk management decisions.

    A method of particle localization for gas chambers (backgammon game method) is presented. The cathode is geometrically cut in such a way that it is possible to establish a simple relation between the signal amplitude on the different parts of the cathode and the position of the nuclear event. The results obtained in the case of x-ray detectors are presented. The application of this method to the localization of neutrons is presently studied [fr

    The objective of the present study was to estimate the effectiveness of the spa and health resort-based treatment of non-alcoholic fatty liver disease in 40 patients at the mean age of 48,8 ± 5.7 years suffering from type 2 diabetes mellitus. All of them received combined therapy including the application of potable Essentuki-Novaya mineral water (20 patients) or Essentuki No 4 water (20 patients). This therapeutic modality resulted in positive dynamics of clinical symptoms of the disease, the functional liver tests, and parameters of intra-hepatic hemodynamics, lipid peroxidation homeostasis, and the hormonal status. It is concluded that the spa and health resort-based treatment with the application of local drinking Essentuki-type mineral waters for the management of non-alcoholic fatty liver disease in the patients presenting with type 2 diabetes mellitus leads to the improvement of the main functions of the liver, stabilizes carbohydrate and lipid metabolism, and prevents progression of the pathological process.

    In contingency of a nuclear emergency event, requiring application of intervention measures on a federal scale, Canada has of a plan ensuring the compatibility of the plans of different provinces and serving as interface between federal and provincial authorities. Exclusive of a nuclear attack against North America, by nuclear emergency it is understood an accident resulting in radionuclide release. This is called the Plan of federal intervention in case of nuclear emergency. 'Sante Canada' is the federal authority responsible for intervention in case of nuclear emergency and it has the task of preparing and coordinating the actions on a federal scale.Should the plan be set in action and if the emergency has repercussions upon the agricultural sector, the sustaining organism will be 'Agriculture and agroalimentaire Canada' which in case of emergency acts through the channels of the National System of intervention in the agro-alimentary sector (SNIUA). The paper presents the objectives, the principles of organization and operation, the responsibilities and the plans which SNIUA has in its charge to implement in case of emergency

    Instruments are essential for accounting, for surveillance and for protection of nuclear materials. The development and application of such instrumentation is reviewed, with special attention to international safeguards applications. Active and passive nondestructive assay techniques are some 25 years of age. The important advances have been in learning how to use them effectively for specific applications, accompanied by major advances in radiation detectors, electronics, and, more recently, in mini-computers. The progress in seals has been disappointingly slow. Surveillance cameras have been widely used for many applications other than safeguards. The revolution in TV technology will have important implications. More sophisticated containment/surveillance equipment is being developed but has yet to be exploited. On the basis of this history, some expectations for instrumentation in the near future are presented

    Vuletic, L; Spalj, S; Peros, K

    2016-02-01

    The primary objective of this study was to assess whether exposing dental students to visual stimuli related to dental profession during the medical physiology seminar could affect their perception of the clinical relevance of the topic. A self-administered questionnaire on attitudes towards medical physiology was conducted amongst 105 students of the School of Dental Medicine in Zagreb, Croatia, aged 19-24 years (80% females) following a seminar on respiratory system physiology. Power-point presentation accompanying the seminar for a total of 52 students (study group) was enriched with pictures related to dental practice in order to assess whether these pictures could make the topic appear more clinically relevant for a future dentist. The results of the survey indicated that dental students in the study group perceived the topic of the seminar as more important for them as future dentists when compared to the perception of the control group (P = 0.025). The results of this survey encourage physiology lecturers to present medical physiology as clinically relevant for dental students whenever possible as this could increase students' interest in the subject and their motivation for learning. Such an approach could be particularly beneficial if there is a significant time gap between basic courses and involvement of students into clinical training for it could promote meaningful learning. © 2014 John Wiley & Sons A/S.

    The objective of our work was the fabrication of single theranostic agent for cancer nanomedicine, which should be easily producible, cheap, biocompatible, spatially and temporally controllable and should have broader range of diagnostic and therapeutic modalities compared with previous works. Here we present the cost efficient and easy to scale-up, modified procedure of synthesis, controlled thin oxide shell formation and polydopamine coating with basic polymerization of dopamine hydrochloride in aqueous solution. Full characterization (HR-TEM, SEM, XRD, HR-TEM-EDAX, HR-TEM-SAED, SEM-EDAX, FTIR, UV-Vis-NIR, TGA, VSM) of novel system comprising of sub-micrometer sized Fe0.65Co0.35@(Fe0.65Co0.35)3O4@PDA highly magnetic (with 226 emu/g value for the metal core Fe0.65Co0.35@(Fe0.65Co0.35)3O4) nanoparticles was done. In vitro MTT cell viability assay on HeLa cells showed no toxicity up to 100 µg/ml of nanoparticles concentration. They are dual mode diagnostic agents with MRI (r2=186.44 mM-1s-1) and X-Ray CT contrasting properties. The HeLa cells was used in in vitro assays. Doxorubicin delivery to the nuclei (laser fluorescence confocal microscopy) and 55% of death (MTT assay) at the concentration of 10 µg/ml was registered. The release of doxorubicin was demonstrated pH sensitive and attenuated in time behavior (temporal control). Specific absorption rate for 470 kHz alternating magnetic field hyperthermia was 180 W/g. Flow cytometry with PI staining demonstrated 60% cell death with 15 min of 808 nm NIR laser exposure at 0.3 kW of laser power and 30 µg/ml of nanoparticles concentration. High magnetic saturation is prerequisite for potential magnetic targeting (special control), the size is within the range of EPR mediated accumulation. Summarizing, above mentioned nanocomposite has 5 theranostic modalities, which is more than previous works and may be considered as good candidate for further in vivo studies as “all-in-one” agent.

    Full Text Available The generation of virtual dynamic learning environments by mental imagery improved physical education of student teachers. Up-to-date studies showed that training computerized simulations improved spatial abilities, especially visualization of the body's movements in space, and enhanced academic achievements. The main program of the research concentrated on creating teaching units focusing on a variety of physical skills through computerized dynamic presentations. The findings showed that as the student teachers practiced the creation of simulations through the PowerPoint Software, it became clear to them how the computer is related to physical activities. Consequently their presentations became highly animated, and applied to the natural environment. The student teachers applied their presentations in their practical classroom and reported about their pupils' progress in physical skills. Moreover the motivation of the student teachers and pupils to both modes of learning, manipulating virtually and physically, was enhanced.

    One way to build knowledge in nursing is to share research findings or clinical program outcomes. The dissemination of these findings is often a difficult final step in a project that has taken months or years to complete. One method of sharing findings in a relaxed and informal setting is a poster presentation. This method is an effective form for presenting findings using an interactive approach. The milieu of a poster presentation enables the presenters to interact and dialogue with colleagues. Guidelines for size and format require that the poster is clear and informative. Application of design helps to create visually appealing posters. This article summarizes elements of designing and conducting a poster presentation.

    This paper discusses alarm filtering and presentation in the control room of nuclear and other process control plants. Alarm generation and presentation is widely recognized as a general process control problem. Alarm systems often fail to provide meaningful alarms to operators. Alarm generation and presentation is an area in which computer aiding is feasible and provides clear benefits. Therefore, researchers have developed several computerized alarm filtering and presentation approaches. This paper discusses problems associated with alarm generation and presentation. Approaches to improving the alarm situation and installation issues of alarm system improvements are discussed. The impact of artificial intelligence (AI) technology on alarm system improvements is assessed. (orig.)

    Since late 1993, Metro Wastewater Reclamation District of Denver (Metro District), a large wastewater treatment plant in Denver, Colorado, has applied Grade I, Class B biosolids to about 52,000 acres of non-irrigated farmland and rangeland near Deer Trail, Colorado. In cooperation with the Metro District in 1993, the U.S. Geological Survey (USGS) began monitoring ground water at part of this site. In 1999, the USGS began a more comprehensive study of the entire site to address stakeholder concerns about the chemical effects of biosolids applications. This more comprehensive monitoring program has recently been extended through 2010. Monitoring components of the more comprehensive study included biosolids collected at the wastewater treatment plant, soil, crops, dust, alluvial and bedrock ground water, and stream bed sediment. Streams at the site are dry most of the year, so samples of stream bed sediment deposited after rain were used to indicate surface-water effects. This presentation will only address biosolids, soil, and crops. More information about these and the other monitoring components are presented in the literature (e.g., Yager and others, 2004a, b, c, d) and at the USGS Web site for the Deer Trail area studies at http://co.water.usgs.gov/projects/CO406/CO406.html. Priority parameters identified by the stakeholders for all monitoring components, included the total concentrations of nine trace elements (arsenic, cadmium, copper, lead, mercury, molybdenum, nickel, selenium, and zinc), plutonium isotopes, and gross alpha and beta activity, regulated by Colorado for biosolids to be used as an agricultural soil amendment. Nitrogen and chromium also were priority parameters for ground water and sediment components. In general, the objective of each component of the study was to determine whether concentrations of priority parameters (1) were higher than regulatory limits, (2) were increasing with time, or (3) were significantly higher in biosolids

  11. Summary of the presentations

    International Nuclear Information System (INIS)

    2002-01-01

    This part summarizes the content of the six following presentations: 1. IAEA requirements/guidance for the decommissioning safety case (Mike Bell, IAEA); 2. Safety case in an EIA context (Patrick O'SULLIVAN, The Netherlands); 3. Plant configuration and the D and D licensing process (Eugenio GIL LOPEZ and Pedro CARBONERAS, Spain); 4. Accident assessment (Ivo TRIPPUTI, Italy; Ingmar LUND, Sweden); 5. Balancing radiological and industrial risk in the safety case (Pascal DEBOODT, Belgium); 6. The safety case for safe store and dormancy periods (Paul WOOLLAM, UK). Following the six presentations, the WPDD members discussed the safety case in an open discussion led by the Topical Session Chair, Frances Taylor. The discussion was wide-ranging, and topics varied from the standards that apply to releases to the environment during safe store, to decommissioning parallels with other major processing industries and facilities (such as oil rigs). Frances Taylor steered the discussion toward addressing the questions that the WPDD Core Group had proposed for the topical session. The Chair, the Rapporteur, and some members of the group sensed that the presentations had covered such an wide variety of issues, and that the content of the presentations themselves differed so greatly, that it would be difficult to distill a position paper from the information gathered, as had been the mandate from the Core Group. In addition, the meaning of the term 'Safety Case' differed greatly among participants in the topical session. Some took the term to mean the analysis and document that the implementor provides to the regulator, describing how operations will be performed safely. Others considered the term to mean the overall safety and risk conditions inherent in a nuclear facility during operations or decommissioning. With the differences in presentations and with the meaning of the terminology remaining unclear, the WPDD participants did not reach consensus conclusions on December 5, 2001

    Metachromatic leukodystrophy (MLD) is a rare demyelinating disease (prevalence 1:40 000), also called arylsulfatase A deficiency (ARS-A), which may present with neurological and psychiatric symptoms. Clinical assessment may be difficult, due to unspecific signs and symptoms. A case is presented of a 16 year-old female patient seen in psychiatry due to behavioural changes, psychosis, and with impaired overall performance. She was initially diagnosed with schizophrenia, but the Nuclear Magnetic Resonance (NMR) scan and laboratory tests lead to the diagnosis of MLD. Copyright © 2016 Asociación Colombiana de Psiquiatría.

    2012-01-01

    We are presenting two cases of Sirenomelia (Mermaid Syndrome), which is an extreme example of the caudal regression syndrome. It invariably presents with lower limb fusion, sacral and pelvic bony anomalies, absent external genitalia, imperforate anus, and renal agenesis or dysgenesis. There are approximately 300 cases reported in the literature, 15% of which are associated with twinning, most often monozygotic. The syndrome of caudal regression is thought to be the result of injury to the caudal mesoderm early in gestation. One of our cases survived for 12 days after birth. This new born had an unusually high anorectal anomaly in which the colon was ending at the level of mid transverse colon, fused lower limbs and genital anomalies. Ultrasound of the abdomen revealed horseshoe kidney. Colostomy was performed on day 2 of life. The second case encountered was a stillborn baby on whom an autopsy was performed. PMID:26023366

    Information management can be a daunting process for clinicians, health care providers and policy makers within the health care industry. This chapter discusses the importance of information classification and information architecture in the information economy and specific challenges faced within the health care industry. The healthcare sector has industry specific requirements for information management, standards and specifications for information presentation. Classification of information based on information criticality and the value in the health care industry is discussed in this paper. Presentation of information with reference to eHealth standards and specifications for healthcare information systems and their key requirements are also discussed, as are information architecture for eHealth implementation in Australia. This chapter also touches on information management and clinical governance since the importance of information governance is discussed by various researchers and how this is becoming of value to healthcare information management.

    Francisella tularensis is a gram-negative coccobacillus that causes a condition commonly referred to as tularemia. There has been a dramatic increase in tularemia cases reported in South Dakota, many of which were challenging to diagnose due to atypical clinical manifestations. We describe an interesting case of pneumonic tularemia and summarize six similar cases, several of which presented with lung nodules suggestive of malignancy. According to the literature, this is only the third outbreak of pneumonic tularemia reported in the U.S. We believe it is important for clinicians to be aware of the increased incidence of tularemia in the area and to be vigilant in the diagnosis and management of these atypically presenting cases.

    In electron probe microanalysis the objective has always been to gain the maximum information from a sample. To this end efforts have been directed at increasing detection efficiency, reducing the size of the excitation volume, analysing more difficult specimens and improving the accuracy of quantitative measurements whilst, at the same time, attempting to minimize the complexity of the analysis. The present paper comments on the progress that has been made in this areas, focuses on the latest hardware and software developments taking place and looks forward to how these may impact on the technique of EPMA.

    We herein describe a second Japanese case of sarcoidosis presenting Addison's disease. A 52-year-old man was diagnosed with sarcoidosis based on clinical and laboratory findings, including bilateral hilar lymphadenopathy and elevated levels of serum angiotensin-converting enzyme and lysozyme, as well as the presence of noncaseating epithelioid granulomas. The patient also exhibited general fatigue, pigmentation, weight loss, hypotension and hyponatremia, suggestive of chronic adrenocortical insufficiency. An endocrine examination confirmed primary adrenocortical insufficiency. This case suggests the direct involvement of sarcoid granuloma in the adrenal glands.

    Counihan, Martin

    2007-01-01

    The basic principles of the Newtonian theory of gravitation are presented in a way which students may find more logically coherent, mathematically accessible and physically interesting than other approaches. After giving relatively simple derivations of the circular hodograph and the elliptical orbit from the inverse-square law, the concept of gravitational energy is developed from vector calculus. It is argued that the energy density of a gravitational field may reasonably be regarded as -g 2 /8πG, and that the inverse-square law may be replaced by a Schwarzschild-like force law without the need to invoke non-Euclidean geometry

    This paper proposes that there is a major error in the present perception of cancer risk from exposure to low level radiation from internal man-made fission products like strontium-90. The author's Second Event theory is discussed which advances the basis that fission products are different in radiation risk terms. Since the scientific community has been so ready to dismiss this idea out of hand, the author also explores scientific culture and scientific revolutions. The evidence that the idea is broadly right is surveyed and finally some studies that could be undertaken to prove or disprove the author's contention are outlined. (UK)

    The radiotherapy is one of the most widely spread and commonly used method in treating tumors of different localization. A detailed analysis of benefits and possible side effects along with evaluation of the risk factors allows preventing one of the most difficult complication, and namely the radiation myelopathy. The delayed form of such a disease is distinguished by a pronounced unfavorable prognosis. The presented case provoked the discussion of difficulties in performing differential diagnosis, as well as the importance of determining the localization of vulnerable tissues as regards the target organ exposed to radiotherapy.

    1988-11-01

    Rett syndrome, a degenerative neurological disorder of girls, has a classical presentation and typical EEG findings. The electroencephalograms (EEGs) of 7 girls whose records have been followed from the onset of symptoms to the age of 5 or more are presented. These findings are tabulated with the Clinical Staging System of Hagberg and Witt-Engerström (1986). The records show a progressive deterioration in background rhythms in waking and sleep. The abnormalities of the background activity may only become evident at 4-5 years of age or during stage 2--the Rapid Destructive Stage. The marked contrast between waking and sleep background may not occur until stage 3--the Pseudostationary Stage. In essence EEG changes appear to lag behind clinical symptomatology by 1-3 years. An unexpected, but frequent, abnormality was central spikes seen in 5 of 7 girls. They appeared to be age related and could be evoked by tactile stimulation in 2 patients. We hypothesize that the prominent 'hand washing' mannerism may be self-stimulating and related to the appearance of central spike discharges.

    This time, we would like to address copyright violations (again) - but with a twist. While previous articles focussed on “Music, videos and the risk for CERN” or on software licences, the focus is now on using photos, music and images “found” on the Web for presentations, publications and web pages…   Just recently, a video produced for CERN and published on YouTube and Facebook used background music from a contemporary popular artist. However, the people responsible failed to obtain the appropriate permission to actually use that music. They thought that having bought it on iTunes was sufficient. But it was not: “buying” means you have the right to listen, but not the right for further distribution or re-publication. As a result, the videos were pulled from YouTube and Facebook. Similarly, how many of us integrate graphics and images “found” on the Web into our presentations?  How many of us...

    Die Urknallmaschine, an Austrian film by Gerd Baldauf, narrated by Norbert Frischauf (Alpha Österreich - ORF, 2009).  In CERN’s gigantic complex particles are accelerated to almost the speed of light, brought to collision and made to divide into even smaller particles. Public opinion of CERN’s research is also divided. Sceptics fear that black holes may be created. Might the goal to study the origin of the world lead to its destruction? The Austrian researcher Norbert Frischauf worked at CERN for many years. With his guidance it is possible to explore the world’s largest research centre, get a glimpse of the fascinating work the scientists do there and take a crash course in particle physics. Die Urknallmaschine will be presented on Friday, 25 June from 13:00 to 14:00 in the Main Auditorium. Language: German

    2015-01-01

    Abdominal pregnancy, a rare diagnosis, belongs to the ectopic pregnancy group, the leading cause of pregnancy related exitus. The positive diagnosis is very difficult to establish most often in an acute setting, leading to a staggering percent of feto-maternal morbidity and mortality. We present the case of 26-weeks-old abdominal pregnancy with partial feto-placental detachment in a patient, after hysteroscopy and in vitro fertilization, which until the acute symptoms that led to emergency laparotomy went unrecognized. The patient recovered completely and satisfactorily after surgery and, due to the high risk of uterine rupture with regard to a second pregnancy, opted for a surrogate mother. Abdominal pregnancy can be regarded as a difficult to establish diagnosis, with a greater chance in case of increased awareness. It is compulsory to be well informed in order not to be surprised by the diagnosis and to apply the correct treatment immediately as the morbidity and mortality rate is elevated.

    Full Text Available Background: Trichinosis is a widespread zoonosis acquired by ingestion of undercooked meat infected with the larvae of Trichinella parasites. The disease has variable clinical manifestations ranging from asymptomatic to fatal. Majority of infections is caused by Trichinella spiralis, although there are some cases caused by other species. The dramatic decline of trichinosis reflects changes in industrial practices and increased public awareness. The majority of human cases are now associated with wild game meat and noncommercial pork. The case of previously healthy, young man with trichinosis is presented. The disease was determined with serologic testing and cured with albendazole. The source of infection has not been determined.Conclusions: In patients with fever, mialgias and eosinophilia infection with tissue nematodes should always be taken in consideration. In those who have recently consumed raw or undercooked pork and wild game meat we should think about trichinosis. The disease is rare in Slovenia.

    Webster, Lee Ann H

    2007-01-01

    Medical practice leadership teams, often consisting primarily of physicians with limited financial backgrounds, must make important business decisions and continuously monitor practice operations. In order to competently perform this duty, they need financial reports that are relevant and easy to understand. This article explores financial reporting and decision-making in a physician practice. It discusses reports and tools, such as ratios, graphs, and comparisons, that practices typically include in their reports. Because profitability and cash flow are often the most important financial considerations for physician practices, reports should generally focus on the impact of various activities and potential decisions upon these concerns. This article also provides communication tips for both those presenting practice financial information and those making the decisions. By communicating effectively, these leaders can best use financial information to improve decision-making and maximize financial performance.

  13. Present energy status

    Energy Technology Data Exchange (ETDEWEB)

    Desprairies, P

    1988-04-01

    This paper reviews the past and present situation of the World Oil Market and assumes future trends and possible future evolution. Low oil prices between 1950 and 1973 have contributed to an exceptional growth of oil demand during more than 20 years which was more and more supplied by OPEC. The oil shocks of 1973 and 1979 have dramatically changed this situation. Some of the most important changes have been the emergence of non-OPEC new oil producers, the growth of substitute energies, especially natural gas and nuclear power, on the supply side; and substantial decrease of energy consumption in many industrialized countries which has greatly reduced oil demand to OPEC on the demand side. Today this situation seems somewhat stabilized (after the reversal of world oil prices in 1986) and OPEC is producing around 18 million b/day as against a producing capacity of about 30 million b/day. It is generally considered that in coming years oil prices will remain relatively low (or occasionally even become lower than today) due to excess oil production capacity and relative abundance of other types of energy. However, many experts think that these trends can be reversed when oil supply will more and more concentrate again in the Middle East; but it is hard to say if this will begin in 1995, 2000, 2010.

  14. The laryngocele; case presentation

    Directory of Open Access Journals (Sweden)

    Gabriel V. Berteșteanu

    2016-05-01

    Full Text Available Laryngocele is a rare pathology, but because of their clinical evolution and the symptoms they generate, they should always be considered as a differential diagnosis when investigating neck masses. A laryngocele is basically a herniation of the mucosa of the laryngeal ventricle (Morgagni's ventricle arising usually from the saccular region. This herniation may remain confined to the larynx - in which case the laryngocele is internal- or expand through the thyro-hyoid membrane into the structures of the neck - thus being called an external laryngocele. Usually the laryngocele has both an internal and external component thus being a mixed laryngocele. Diagnosis of laryngoceles still relies heavily on clinical signs such as tympanism, easily depressible neck mass, indirect laryngoscopy, but is now simplified by imagistic investigations (ultrasound, CT and MRI. However, the treatment of this condition is exclusively surgical and consists of total excision of the laryngocele, as well as proper identification of the point of origin from the saccule and also the final suture of the breach in order to prevent recurrence. Investigation of possible causes of obstruction of the laryngeal ventricle should always be performed (because of the possibility of an underlying malignancy as well as a follow-up protocol of the patient, given the risk of relapse. We present a recently diagnosed case of a 32 year old man with mixed laryngocele, which we have operated in our clinic.

    The author discuss the up to date interpretation of the concept of antibiotics and antibiotic research, as well as the present role of various natural, semisynthetic and synthetic antibiotic compounds in various areas of the human therapy. The origin and the total number of all antibiotics and applied antibiotics in the practice, as well as the bioactive microbial metabolites (antibiotics) in other therapeutical, non-antibiotic fields (including agriculture) are also reviewed. The author discusses main problems, such as increasing (poly)resistance, virulence of pathogens and the non-scientific factors (such as a decline of research efforts and their sociological, economic, financial and regulatory reasons). A short summary of the history of Hungarian antibiotic research is also provided. The author briefly discusses the prospects in the future and the general advantages of the natural products over synthetic compounds. It is concluded that new approaches for the investigation of the unlimited possibilities of the living world are necessary. The discovery of new types or simply neglected (micro)organisms and their biosynthetic capabilities, the introduction of new biotechnological and genetic methods (genomics, metagenom, genome mining) are absolutely required in the future.

    2003-04-01

    The IKONOS satellite has been operational since January 2000 and was the first commercial satellite collecting imagery with 1 meter resolution. The current life expectancy of the satellite is 10 years. Since the launch, Space Imaging Inc. (the owner of the satellite) supplied IKONOS imagery to users in many vertical markets, such as: agriculture, defense, oil & gas and telecommunications. This oral presentation will give comprehensive information about IKONOS and the future: * Block II, the successor of IKONOS. Space Imaging expects to launch in 2004 a new high-resolution satellite, ensuring both continuity and (for some years) a tandem operation with IKONOS, greatly improving the availability of imagery. * Space Imaging affiliates. IKONOS imagery collected, processed and sold by regional affiliates. These regional affiliates are strategically located around the world, like Japan Space Imaging (Tokyo), Space Imaging Middle East (Dubai) and Space Imaging Eurasia (Ankara, Turkey). * Technical briefing IKONOS. IKONOS (compared to other commercial high-resolution satellites) has superior collection capabilities. Due to, the higher orbit altitude, local reception of the imagery, bi-directional scanning and the high agility of the satellite, is the IKONOS satellite capable to collect the imagery relative quickly.

    Since the development of quantum physics in the early part of the 1900s, this field of study has made remarkable contributions to our civilization. Some of these advances include lasers, light-emitting diodes (LED), sensors, spectroscopy, quantum dots, quantum gravity and quantum entanglements. In 1998, the NASA Langley Research Center established a quantum technology committee to monitor the progress in this area and initiated research to determine the potential of quantum technology for future NASA missions. The areas of interest in quantum technology at NASA included fundamental quantum-optics materials associated with quantum dots and quantum wells, device-oriented photonic crystals, smart optics, quantum conductors, quantum information and computing, teleportation theorem, and quantum energetics. A brief review of the work performed, the progress made in advancing these technologies, and the potential NASA applications of quantum technology will be presented.

    Full Text Available El presentismo es visto generalmente como un mal necesario en historiografía. Este artículo explora lo positivo de esta inevitabilidad. Aplicando un enfoque filosófico al análisis discursivo en la tradición de la nueva historia cultural, se distingue -de una parte-¿ entre un uso estratégico del presentismo, y -de otra- un enfoque racionalista en historia. El artículo concluye considerando algunas implicaciones políticas en historiografía de las explicaciones racionalistas y de las explicaciones estratégicamente presentistas. Los modos de comprensión racionalistas inscriben las expectativas del pasado en las visiones del futuro; asignando al historiador el papel de profeta; y perpetuando nociones de agentes ahistóricos. En contraste, las historias estratégicamente presentistas incorporan una orientación que deliberadamente emplea las lentes y perspectivas del presente en orden a tener en cuenta supuestos y perspectivas actuales. Cuando las asunciones son examinadas en relación a las perspectivas presentistas, dichos presupuestos sueltan su rienda en el pensamiento. Dado que el presentismo es inevitable, no debe ser desestimado por completo, sino que debe ser una cuestión sondeada y examinada críticamente. Con dicho foco, el presentismo estratégico en la historiografía debe posibilitar una reflexión sobre los límites de lo que es posible pensar.

    Implementing a sustainable local energy policy involves a long term reflection on the general interest, energy efficiency, distributed generation and environmental protection. Providing services on a market involves looking for activities that are profitable, if possible in the 'short-term'. The aim of this conference is to analyse the possibility of reconciling these apparently contradictory requirements and how this can be achieved. This conference brings together the best specialists from European municipalities as well as important partners for local authorities (energy agencies, service companies, institutions, etc.) in order to discuss the public-private partnerships concerning the various functions that municipalities may perform in the energy field as consumers and customers, planners and organizers of urban space and rousers as regards inhabitants and economic players of their areas. This document contains the summaries of the following presentations: 1 - Performance contracting: Bulgarian municipalities use private capital for energy efficiency improvement (K. VIDOLOV, Varna (BG)), Contracting experiences in Swiss municipalities: consistent energy policy thanks to the Energy-city label (B. DUFOUR-FALLOT and T.

    Full Text Available The database systems have nowadays an increasingly important role in the knowledge-based society, in which computers have penetrated all fields of activity and the Internet tends to develop worldwide. In the current informatics context, the development of the applications with databases is the work of the specialists. Using databases, reach a database from various applications, and also some of related concepts, have become accessible to all categories of IT users. This paper aims to summarize the curricular area regarding the fundamental database systems issues, which are necessary in order to train specialists in economic informatics higher education. The database systems integrate and interfere with several informatics technologies and therefore are more difficult to understand and use. Thus, students should know already a set of minimum, mandatory concepts and their practical implementation: computer systems, programming techniques, programming languages, data structures. The article also presents the actual trends in the evolution of the database systems, in the context of economic informatics.

    structure (chemical order, anisotropy, charge transfer, magnetic order) versus an external parameter like temperature, pressure, magnetic or electric field. Modern crystallography is also extended to the study of very small crystals, powders, ill-ordered or non-crystallized materials. Thus presently, crystallography is concerned with any solid that “scatters” an incident beam. Nevertheless, as quoted by A. Guinier, “the problems facing crystallographers have only changed, ... new ones have appeared which require reflection and imagination, ... and which in turn may still bring much joy to all those who like crystallography” [4]. Such developments open up crystallography to modern materials like artificial ones and nanostructures with low- and/or multi-scaled-periodicities and/or extremely small “crystal size” and to materials of the “real world”, with mixtures of phases and/or amorphous contribution and/or defects, a common characteristic of ancient materials analysed in patrimonial research. In our contribution we will show by selected examples that these improvements were allowed (i) by the use of powerful sources, apparatus and detectors which allow micro-diffraction, in-situ diffraction, spectroscopy, resonant scattering, inelastic scattering, coherent scattering, (ii) by the development of methods like diffraction anomalous fine structure (DAFS), pair distribution function (PDF), simulated annealing, single object reconstruction, (iii) by combination of scattering and spectroscopy and by combination of scattering and microscopy. Such combination of different approaches is very efficient and, as said by H. Curien at the IUCr Bordeaux Congress in 1990, “in crystallography, there is a constant alternation between the crystal space and its associated reciprocal space, ... the alternation between experiment and model building is another feature of crystallography activity ..., the crystallographer relies both on his computer and on his diffractometer

    History of the production and use of tritium, as well as handling techniques, are reviewed. Handling techniques first used at Lawrence Livermore National Laboratory made use of glass vacuum systems and relatively crude ion chambers for monitoring airborne activity. The first use of inert atmosphere glove boxes demonstrated that uptake through the skin could be a serious personnel exposure problem. Growing environmental concerns in the early 1970's resulted in the implementation by the Atomic Energy Commission of a new criteria to limit atmospheric tritium releases to levels as low as practicable. An important result of the new criteria was the development of containment and recovery systems to capture tritium rather than vent it to the atmosphere. The Sandia National Laboratories, Livermore, Tritium Research Laboratory containment and decontamination systems are presented as a typical example of this technology. The application of computers to control systems is expected to provide the greatest potential for change in future tritium handling practices

    The increased demand for natural gas leads to global integration of markets, leading to decisions that cover the various technologies of transportation, noting the specific locations. The transport of natural gas considered more traditional (Liquefied Natural Gas and Pipeline) often unviable economically areas of operation due to cost. In this case, there are alternative technologies to reduce those costs. The article is to compare the technologies of transport, using the methodology of the Net Present Value (VPL) to identify one that has more positive VPL, which is the most profitable. Thus, in search of validate the results of SUBERO et al. (2004) for gas transport by Pipelines, Liquefied Natural Gas and Compressed Natural Gas. In addition, they are compared these results with the method of VPL and with the economic analysis presented in using the payback period of CHANG (2001) and SANTAREM et al. (2007). It was found that the results obtained in Brazil were identical to those obtained by CHANG (2001) and SUBERO et al. (2007), saving only some differences in magnitude due to the specific characteristics of the Brazilian economy. In other words, for the Brazilian case, the technology of Compressed Natural Gas (CNG) was the most economically viable with the method of VPL, followed by technology, Pipeline and Liquefied Natural Gas (LNG), regardless of the interest rates of 10% and 6.5% and periods of 20 and 30 years. The contribution of this work is to show that despite of the method, payback or VPL, the various alternatives for transporting natural gas to Brazil have the same ranking and economic viability.

    The conformational space available to the flexible molecule α-D-Manp-(1-->2)-α-D-Manp-OMe, a model for the α-(1-->2)-linked mannose disaccharide in N- or O-linked glycoproteins, is determined using experimental data and molecular simulation combined with a maximum entropy approach that leads to a converged population distribution utilizing different input information. A database survey of the Protein Data Bank where structures having the constituent disaccharide were retrieved resulted in an ensemble with >200 structures. Subsequent filtering removed erroneous structures and gave the database (DB) ensemble having three classes of mannose-containing compounds, viz., N- and O-linked structures, and ligands to proteins. A molecular dynamics (MD) simulation of the disaccharide revealed a two-state equilibrium with a major and a minor conformational state, i.e., the MD ensemble. These two different conformation ensembles of the disaccharide were compared to measured experimental spectroscopic data for the molecule in water solution. However, neither of the two populations were compatible with experimental data from optical rotation, NMR (1)H,(1)H cross-relaxation rates as well as homo- and heteronuclear (3)J couplings. The conformational distributions were subsequently used as background information to generate priors that were used in a maximum entropy analysis. The resulting posteriors, i.e., the population distributions after the application of the maximum entropy analysis, still showed notable deviations that were not anticipated based on the prior information. Therefore, reparameterization of homo- and heteronuclear Karplus relationships for the glycosidic torsion angles Φ and Ψ were carried out in which the importance of electronegative substituents on the coupling pathway was deemed essential resulting in four derived equations, two (3)J(COCC) and two (3)J(COCH) being different for the Φ and Ψ torsions, respectively. These Karplus relationships are denoted

    Over the past 5 years, a great deal of information about the early course of autism spectrum disorder (ASD) has emerged from longitudinal prospective studies of infants at high risk for developing ASD based on a previously diagnosed older sibling. The current article describes early ASD symptom presentations and outlines the rationale for defining a new disorder, Early Atypical Autism Spectrum Disorder (EA-ASD) to accompany ASD in the new revision of the ZERO TO THREE Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood (DC:0-5) (in press) alternative diagnostic classification manual. EA-ASD is designed to identify children who are 9 to 36 months of age presenting with a minimum of (a) two social-communication symptoms and (b) one repetitive and restricted behavior symptom as well as (c) evidence of impairment, with the intention of providing these children with appropriately tailored services and improving the likelihood of optimizing their development. © 2016 Michigan Association for Infant Mental Health.

    In the last two decades many laboratories around the world, notably Argonne (ANL), TJNAF (formerly CEBAF), CERN, DESY and KEK, decided to develop the technology of superconducting (SC) accelerating cavities. The aim was either to increase the accelerator energy or to save electrical consumption or both. This technology has been used extensively in the operating machines showing good performances and strong reliability. At present, the technology using bulk niobium (Nb) or Nb coated on copper (Cu) is mature enough to be applied for many different applications, such as synchrotron light sources and spallation neutron drivers. Results, R&D work and future projects will be presented with emphasis on application to linear accelerators.

THE IMPACT OF MULTIMEDIA PRESENTATIONS ON SCIENCE LEARNING Peter G. Schrader University of Nevada Las Vegas, USA pg.schrader@unlv.edu Eric E. Rapp ericrapp@icloud.com ABSTRACT In K-12 school settings in the United States, there is a preponderance of information delivered via multimedia to students everyday (e.g., visual aids found in science textbooks, electronic tablets, streamed video content, web pages, animations, and PowerPoint presentations. The cognitive theory of multimedia learning (CTML outlines numerous principles associated with learning from and with multimedia (Mayer, Hegarty, Mayer, & Cambell, 2005. However, the bulk of the research like the CTML has been conducted using college age students (Jones, 2010; McTigue, 2009.

    International Nuclear Information System (INIS)

    Koch, Florian

    2008-01-01

    Physics comes up with models that invoke noncommutative structures in configuration space. Such structures are dual to the deformed coalgebra sector of a represented symmetry algebra. In the mean time such deformations are performed in terms of the symmetry algebra itself via twists or quasitriangular structures. One might thus find oneself in the bad situation that the symmetry algebra is not large enough to provide the required twist that dually matches the noncommutative structure found. It thus has to remain in the unpleasant state of being without any notion of symmetry. We show how starproducts can be pushed to twists by introducing a larger algebra that accommodates any finite dimensional representation of a Lie-algebra. This new algebra is similar to a Heisenberg-algebra but in contrast to the latter can be enhanced to a Hopf-algebra. Some Examples are given. (author)

    The encoding and representation of visually presented clock times was investigated in three experiments utilizing a comparative judgment task. Experiment 1 explored the effects of comparing times presented in different formats (clock face, digit, or word), and Experiment 2 examined angular distance effects created by varying positions of the hands on clock faces. In Experiment 3, encoding and processing differences between clock faces and digitally presented times were directly measured. Same/different reactions to digitally presented times were faster than to times presented on a clock face, and this format effect was found to be a result of differences in processing that occurred after encoding. Angular separation also had a limited effect on processing. The findings are interpreted within the framework of theories that refer to the importance of representational codes. The applicability to the data of Bank's semantic-coding theory, Paivio's dual-coding theory, and the levels-of-processing view of memory are discussed.

    2011-09-01

    Full Text Available Molecular Imprinting Technology (MIT is a technique to design artificial receptors with a predetermined selectivity and specificity for a given analyte, which can be used as ideal materials in various application fields. Molecularly Imprinted Polymers (MIPs, the polymeric matrices obtained using the imprinting technology, are robust molecular recognition elements able to mimic natural recognition entities, such as antibodies and biological receptors, useful to separate and analyze complicated samples such as biological fluids and environmental samples. The scope of this review is to provide a general overview on MIPs field discussing first general aspects in MIP preparation and then dealing with various application aspects. This review aims to outline the molecularly imprinted process and present a summary of principal application fields of molecularly imprinted polymers, focusing on chemical sensing, separation science, drug delivery and catalysis. Some significant aspects about preparation and application of the molecular imprinting polymers with examples taken from the recent literature will be discussed. Theoretical and experimental parameters for MIPs design in terms of the interaction between template and polymer functionalities will be considered and synthesis methods for the improvement of MIP recognition properties will also be presented.

  3. Isolated Torticollis May Present as an Atypical Presentation of Meningitis

    Directory of Open Access Journals (Sweden)

    Roger Chirurgi

    2012-01-01

    Full Text Available Background. Bacterial meningitis is a life-threatening medical emergency that requires urgent diagnosis and treatment. Diagnosis is infrequently missed if the patient presents with the classic symptoms of fever, headache, rash, nuchal rigidity, or Kernig or Brudzinski sign. However, it may be less obvious in neonates, elderly, or immunocompromised patients. Meningitis which presents as isolated torticollis, without any other signs or symptoms, is exceedingly rare. Objective. To identify an abnormal presentation of meningitis in an adult immunocompromised patient. Case Report. We present a case of an adult diabetic male who presented multiple times to the ED with complaint of isolated torticollis, who ultimately was diagnosed with bacterial meningitis. Conclusion. We propose that in the absence of sufficient explanation for acute painful torticollis in an immunocompromised adult patient, further evaluation, possibly including a lumbar puncture may be warranted.

    The utilization of PUSPATI TRIGA Mark II Reactor (PTR) has increased reasonably well since its commissioning last year. PTR was used mainly for training of operators, neutron flux measurements and neutron activation analysis. However, the present utilization data indicates that further increase in PTR utilization to include teaching and the usage of the beam ports is desirable. Some possible areas of PTR applications in the future in relevance to our needs are also described in this paper. (author)

  6. Presentation planning using an integrated knowledge base

    Science.gov (United States)

    Arens, Yigal; Miller, Lawrence; Sondheimer, Norman

    1988-01-01

    A description is given of user interface research aimed at bringing together multiple input and output modes in a way that handles mixed mode input (commands, menus, forms, natural language), interacts with a diverse collection of underlying software utilities in a uniform way, and presents the results through a combination of output modes including natural language text, maps, charts and graphs. The system, Integrated Interfaces, derives much of its ability to interact uniformly with the user and the underlying services and to build its presentations, from the information present in a central knowledge base. This knowledge base integrates models of the application domain (Navy ships in the Pacific region, in the current demonstration version); the structure of visual displays and their graphical features; the underlying services (data bases and expert systems); and interface functions. The emphasis is on a presentation planner that uses the knowledge base to produce multi-modal output. There has been a flurry of recent work in user interface management systems. (Several recent examples are listed in the references). Existing work is characterized by an attempt to relieve the software designer of the burden of handcrafting an interface for each application. The work has generally focused on intelligently handling input. This paper deals with the other end of the pipeline - presentations.

  7. Ceramics: past, present, and future.

    Science.gov (United States)

    Lemons, J E

    1996-07-01

    The selection and application of synthetic materials for surgical implants has been directly dependent upon the biocompatibility profiles of specific prosthetic devices. The early rationale for ceramic biomaterials was based upon the chemical and biochemical inertness (minimal bioreactivity) of elemental compounds constituted into structural forms (materials). Subsequently, mildly reactive (bioactive), and partially and fully degradable ceramics were identified for clinical uses. Structural forms have included bulk solids or particulates with and without porosities for tissue ingrowth, and more recently, coatings onto other types of biomaterial substrates. The physical shapes selected were application dependent, with advantages and disadvantages determined by: (1) the basic material and design properties of the device construct; and (2) the patient-based functional considerations. Most of the ceramics (bioceramics) selected in the 1960s and 1970s have continued over the long-term, and the science and technology for thick and thin coatings have evolved significantly over the past decade. Applications of ceramic biomaterials range from bulk (100%) ceramic structures as joint and bone replacements to fully or partially biodegradable substrates for the controlled delivery of pharmaceutical drugs, growth factors, and morphogenetically inductive substances. Because of the relatively unique properties of bioceramics, expanded uses as structural composites with other biomaterials and macromolecular biologically-derived substances are anticipated in the future.

  14. Atypical presentations of Wolframs syndrome

    Directory of Open Access Journals (Sweden)

    S Saran

    2012-01-01

    Full Text Available Background: Wolfram syndrome is a rare hereditary or sporadic neurodegenerative disorder also known as DIDMOAD. The classically described presentation is of insulin-dependent diabetes, followed by optic atrophy, central diabetes insipidus, and sensory neural deafness. Also included are less well-described presentations of Wolframs syndrome. We here present three cases of atypical presentation of this syndrome. Case 1: A 15-year-old boy with insulin-dependent diabetes was presented for evaluation of depressive symptoms associated with suicidal tendency. Neuropsychiatric manifestations are described with Wolframs syndrome, and wolframin gene, in recessive inheritance, is associated with psychiatric illnesses without other manifestations of Wolframs syndrome. Case 2: A 17-year-old diabetic boy on insulin with good control of blood sugar presented for evaluation of delayed puberty. Central hypogonadism and other anterior pituitary hormone dysfunctions are the less publicized hormone dysfunctions in Wolframs syndrome. Case 3: A 23-year-old female who was on insulin for diabetes for the past 14 years, got admitted for evaluation of sudden loss of vision. This patient had developed a vitreous hemorrhage and, on evaluation, was found to have optic atrophy, sensory neural hearing loss, and diabetes insipidus, and presented differently from the gradual loss of vision described in Wolframs syndrome. Conclusion: Wolframs syndrome being a multisystem degenerative disorder can have myriad other manifestations than the classically described features. Neuropsychiatric manifestations, depression with suicidal risk, central hypogonadism, and secondary adrenal insufficiency are among the less well-described manifestations of this syndrome.

    Morandi, S; Manna, A; Sabattini, E; Porcellini, A

    1996-08-01

    We describe a case of a very unusual presentation of rhabdomyosarcoma. An 18-year-old woman presented with symptoms and signs compatible with acute leukemia. The bone marrow picture showed diffuse involvement sustained by undifferentiated blasts that turned out to be of striated muscle origin by immunochemistry. While it is well known that rhabdomyosarcoma may metastasize to the bone marrow, extensive marrow involvement with leukemic spread as a unique clinical manifestation is extremely rare. Our observation further confirms the need to consider rhabdomyosarcoma among the possible differential diagnoses in patients who present with a leukemic picture and atypical blasts lacking all hematopoietic markers.

    Science.gov (United States)

    Scripture, D L

    1998-02-01

    Hyperthyroidism is the most common disorder of the thyroid. Patients typically present with complaints consistent with a hypermetabolic state, including nervousness, weight loss, heat intolerance, palpitations, irritability, and tremor. This case report reviews a 34-year-old woman who presented with unilateral upper extremity weakness, weight gain, and an episode of atrial fibrillation, the latter coinciding with a 36-hour lack of sleep and excess alcohol and caffeine intake. Although an extensive neurologic evaluation failed to identify any abnormality, the patient's laboratory analysis revealed elevations in thyroxine (T4) and triiodothyronine (T3) levels with unsuppressed thyroid-stimulating hormone levels. Subsequent treatment with the antithyroid drug methimazole (Tapazole) provided complete relief of symptoms. This case report illustrates how health care providers can be diverted to pursue a neurologic etiology when muscle weakness presents as a unilateral symptom. Plausible alternative causes for muscle weakness and other symptoms are presented.

    2016-06-23

    Thyrotoxic crisis is a medical emergency requiring early diagnosis and urgent management, which can be challenging due to its diverse clinical presentations. While common presentations include fever, sweating, palpitations, tremors and confusion, presence of jaundice is rare. We report a 35-year-old male who presented with jaundice due to cholestasis along with other features of thyrotoxic crisis due to Graves' disease. He had a good clinical recovery with resolution of cholestasis following treatment for thyrotoxic crisis. Jaundice can be a rare manifestation of thyrotoxic crisis, and should be considered in the differential diagnosis when other clinical features of thyrotoxic crisis are present. However secondary causes of jaundice should be looked into and excluded.

  3. A centralized audio presentation manager

    Energy Technology Data Exchange (ETDEWEB)

    Papp, A.L. III; Blattner, M.M.

    1994-05-16

    The centralized audio presentation manager addresses the problems which occur when multiple programs running simultaneously attempt to use the audio output of a computer system. Time dependence of sound means that certain auditory messages must be scheduled simultaneously, which can lead to perceptual problems due to psychoacoustic phenomena. Furthermore, the combination of speech and nonspeech audio is examined; each presents its own problems of perceptibility in an acoustic environment composed of multiple auditory streams. The centralized audio presentation manager receives abstract parameterized message requests from the currently running programs, and attempts to create and present a sonic representation in the most perceptible manner through the use of a theoretically and empirically designed rule set.

    Kathleen Frances Parthe

    2014-11-01

    Full Text Available A close reading of the journalism, correspondence, and memoirs of Alexander Herzen (1812–1870 yields a finely tuned relationship to past, present, and future, but not a complete philosophy of history. Herzen described no system, but repeated key metaphors (e.g., the libretto and concepts (e.g. contingency that reflected his understanding of the historical process. For Herzen, history became interesting when it was relieved of predetermined plots and algebraic formulas. However much he studied Russia’s past and planned its future, his preference was for the present, where freedom is most fully experienced in debate and in the need to choose a path forward. He understood the instrumentality of history in how the lives of ordinary people were affected, which remained his measure of progress. Herzen was a “historian of the present,” and his insights are remarkably applicable to twenty-first-century Russia.

    2017-07-26

    The multifaceted role of biological membranes prompted early the development of artificial lipid-based models with a primary view of reconstituting the natural functions in vitro so as to study and exploit chemoreception for sensor engineering. Over the years, a fair amount of knowledge on the artificial lipid membranes, as both, suspended or supported lipid films and liposomes, has been disseminated and has helped to diversify and expand initial scopes. Artificial lipid membranes can be constructed by several methods, stabilized by various means, functionalized in a variety of ways, experimented upon intensively, and broadly utilized in sensor development, drug testing, drug discovery or as molecular tools and research probes for elucidating the mechanics and the mechanisms of biological membranes. This paper reviews the state-of-the-art, discusses the diversity of applications, and presents future perspectives. The newly-introduced field of artificial cells further broadens the applicability of artificial membranes in studying the evolution of life.

    Nuno Ferreira

    2015-12-01

    Full Text Available Hemophilia A is a X-linked hereditary condition that lead to decreased factor VIII activity, occurs mainly in males. Decreased factor VIII activity leads to increased risk of bleeding events. During neonatal period, diagnosis is made after post-partum bleeding complication or unexpected bleeding after medical procedures. Subgaleal hemorrhage during neonatal period is a rare, severe extracranial bleeding with high mortality and usually related to traumatic labor or coagulation disorders. Subgaleal hemorrhage complications result from massive bleeding. We present a neonate with unremarkable family history and uneventful pregnancy with a vaginal delivery with no instrumentation, presenting with severe subgaleal bleeding at 52 hours of life. Aggressive support measures were implemented and bleeding managed. The unexpected bleeding lead to a coagulation study and the diagnosis of severe hemophilia A. There were no known sequelae. This case shows a rare hemophilia presentation reflecting the importance of coagulation studies when faced with unexplained severe bleeding.

However, care should be used in drawing inferences from this correlation, since system performance depends on a number of factors other than detector selection and design characteristics. (orig.)

    The impact of quantum technology will be profound and far-reaching: secure communication networks for consumers, corporations and government; precision sensors for biomedical technology and environmental monitoring; quantum simulators for the design of new materials, pharmaceuticals and clean energy devices; and ultra-powerful quantum computers for addressing otherwise impossibly large datasets for machine learning and artificial intelligence applications. However, engineering quantum systems and controlling them is an immense technological challenge: they are inherently fragile; and information extracted from a quantum system necessarily disturbs the system itself. Of the various approaches to quantum technologies, photons are particularly appealing for their low-noise properties and ease of manipulation at the single qubit level. We have developed an integrated waveguide approach to photonic quantum circuits for high performance, miniaturization and scalability. We will described our latest progress in generating, manipulating and interacting single photons in waveguide circuits on silicon chips.

  20. Intermetallics: past, present and future

    Full Text Available Intermetallics have seen extensive world-wide attention over the past decades. For the most part these studies have examined multi-phase aluminide based alloys, because of their high stiffness, combined with reasonable strength and ductility, good structural stability and oxidation resistance, and attempted to improve current Ni-base superalloys, Ti-base alloys, or Fe-base stainless steels for structural aerospace applications. The current status of development and application of such materials is briefly reviewed. Future developments are taking intermetallics from the realm of "improved high-temperature but low-ductility metallic alloys" into the realm of "improved aggressive-environment, high-toughness ceramic-like alloys". Such evolution will be outlined.

    Durante los últimos décadas ha habido un desarrollo de los intermetálicos, sobre todo por aplicaciones estructurales a alta temperatura en aplicaciones aeroespaciales, donde, por su rigidez alta, en combinación con una resistencia mecánica y ductilidad razonable, su buena estabilidad estructural y resistencia a la oxidación, han sido vistos como versiones avanzadas y mejoradas de las aleaciones metálicas como, por ejemplo, las superaleaciones a base de nitrógeno y las aleaciones de titanio. Se discute el desarrollo importante durante las últimas décadas, y también los nuevos desarrollos probables durante los próximos años. Se podrían ver los intermetálicos como versiones mejoradas de los cerámicos.
