    1996-01-01

    The Mission of the National Conversion Pilot Project - to demonstrate, at the Rocky Flats Site, the feasibility of economic conversion of DOE Sites - is succeeding. Contaminated facilities worth $92 million are being cleaned and readied for reuse by commercial industry to manufacture products needed in the DOE cleanup and elsewhere. Former Rocky Flats workers have been hired, recultured, are conducting the cleanup and are expected to perform the future manufacturing by recycling DOE RSM and other metals requiring special environmental controls. Stakeholder sway over project activities is welcome and strong

  2. ESO unveils an amazing, interactive, 360-degree panoramic view of the entire night sky

    2009-09-01

    The first of three images of ESO's GigaGalaxy Zoom project - a new magnificent 800-million-pixel panorama of the entire sky as seen from ESO's observing sites in Chile - has just been released online. The project allows stargazers to explore and experience the Universe as it is seen with the unaided eye from the darkest and best viewing locations in the world. This 360-degree panoramic image, covering the entire celestial sphere, reveals the cosmic landscape that surrounds our tiny blue planet. This gorgeous starscape serves as the first of three extremely high-resolution images featured in the GigaGalaxy Zoom project, launched by ESO within the framework of the International Year of Astronomy 2009 (IYA2009). GigaGalaxy Zoom features a web tool that allows users to take a breathtaking dive into our Milky Way. With this tool users can learn more about many different and exciting objects in the image, such as multicoloured nebulae and exploding stars, just by clicking on them. In this way, the project seeks to link the sky we can all see with the deep, "hidden" cosmos that astronomers study on a daily basis. The wonderful quality of the images is a testament to the splendour of the night sky at ESO's sites in Chile, which are the most productive astronomical observatories in the world. The plane of our Milky Way Galaxy, which we see edge-on from our perspective on Earth, cuts a luminous swath across the image. The projection used in GigaGalaxy Zoom place the viewer in front of our Galaxy with the Galactic Plane running horizontally through the image - almost as if we were looking at the Milky Way from the outside. From this vantage point, the general components of our spiral galaxy come clearly into view, including its disc, marbled with both dark and glowing nebulae, which harbours bright, young stars, as well as the Galaxy's central bulge and its satellite galaxies. The painstaking production of this image came about as a collaboration between ESO, the renowned

    Native Americans are poorly represented in all science, technology and engineering fields. This under- representation results from numerous cultural, economic, and historical factors. The Elwha Science Education Project (ESEP), initiated in 2007, strives to construct a culturally-integrated, geoscience education program for Native American young people through engagement of the entire tribal community. The ESEP has developed a unique approach to informal geoscience education, using environmental restoration as a centerpiece. Environmental restoration is an increasingly important goal for tribes. By integrating geoscience activities with community tradition and history, project stakeholders hope to show students the relevance of science to their day-to-day lives. The ESEP's strength lies in its participatory structure and unique network of partners, which include Olympic National Park; the non-profit, educational center Olympic Park Institute (OPI); a geologist providing oversight and technical expertise; and the Lower Elwha Tribe. Lower Elwha tribal elders and educators share in all phases of the project, from planning and implementation to recruitment of students and discipline. The project works collaboratively with tribal scientists and cultural educators, along with science educators to develop curriculum and best practices for this group of students. Use of hands-on, place-based outdoor activities engage students and connect them with the science outside their back doors. Preliminary results from this summer's middle school program indicate that most (75% or more) students were highly engaged approximately 90% of the time during science instruction. Recruitment of students has been particularly successful, due to a high degree of community involvement. Preliminary evaluations of the ESEP's outcomes indicate success in improving the outlook of the tribe's youth towards the geosciences and science, in general. Future evaluation will be likewise participatory

    This volume contains papers from the Short Thematic Program on Rational Points, Rational Curves, and Entire Holomorphic Curves and Algebraic Varieties, held from June 3-28, 2013, at the Centre de Recherches Mathématiques, Université de Montréal, Québec, Canada. The program was dedicated to the study of subtle interconnections between geometric and arithmetic properties of higher-dimensional algebraic varieties. The main areas of the program were, among others, proving density of rational points in Zariski or analytic topology on special varieties, understanding global geometric properties of rationally connected varieties, as well as connections between geometry and algebraic dynamics exploring new geometric techniques in Diophantine approximation.

  6. CMIP5-based global wave climate projections including the entire Arctic Ocean

    Science.gov (United States)

    Casas-Prat, M.; Wang, X. L.; Swart, N.

    2018-03-01

    This study presents simulations of the global ocean wave climate corresponding to the surface winds and sea ice concentrations as simulated by five CMIP5 (Coupled Model Intercomparison Project Phase 5) climate models for the historical (1979-2005) and RCP8.5 scenario future (2081-2100) periods. To tackle the numerical complexities associated with the inclusion of the North Pole, the WAVEWATCH III (WW3) wave model was used with a customized unstructured Spherical Multi-Cell grid of ∼100 km offshore and ∼50 km along coastlines. The climate model simulated wind and sea ice data, and the corresponding WW3 simulated wave data, were evaluated against reanalysis and hindcast data. The results show that all the five sets of wave simulations projected lower waves in the North Atlantic, corresponding to decreased surface wind speeds there in the warmer climate. The selected CMIP5 models also consistently projected an increase in the surface wind speed in the Southern Hemisphere (SH) mid-high latitudes, which translates in an increase in the WW3 simulated significant wave height (Hs) there. The higher waves are accompanied with increased peak wave period and increased wave age in the East Pacific and Indian Oceans, and a significant counterclockwise rotation in the mean wave direction in the Southern Oceans. The latter is caused by more intense waves from the SH traveling equatorward and developing into swells. Future wave climate in the Arctic Ocean in summer is projected to be predominantly of mixed sea states, with the climatological mean of September maximum Hs ranging mostly 3-4 m. The new waves approaching Arctic coasts will be less fetch-limited as ice retreats since a predominantly southwards mean wave direction is projected in the surrounding seas.

  7. Multiple Clustering Views via Constrained Projections

    DEFF Research Database (Denmark)

    Dang, Xuan-Hong; Assent, Ira; Bailey, James

    2012-01-01

    Clustering, the grouping of data based on mutual similarity, is often used as one of principal tools to analyze and understand data. Unfortunately, most conventional techniques aim at finding only a single clustering over the data. For many practical applications, especially those being described...... in high dimensional data, it is common to see that the data can be grouped into different yet meaningful ways. This gives rise to the recently emerging research area of discovering alternative clusterings. In this preliminary work, we propose a novel framework to generate multiple clustering views....... The framework relies on a constrained data projection approach by which we ensure that a novel alternative clustering being found is not only qualitatively strong but also distinctively different from a reference clustering solution. We demonstrate the potential of the proposed framework using both synthetic...

    Fernando Sfair Kinker

    2016-04-01

    Full Text Available This article discusses the issue of unique therapeutic projects within the mental health services built in the Brazilian psychiatric reform process. Starting from the concepts that have gained strength in both the psychiatric reform as in the collective health, this study proposes that current notions of the therapeutic project still are influenced by biological, psychological or social paradigms that simplify the complexity of the experience suffered by the subjects. Despite therapeutic projects are an essential achievement for the qualification of mental health care, it is still necessary to produce an epistemological rupture in the relationship with mental suffering so that they can achieve the greatest potential for transformation. Therefore, the article suggests that the practice of therapeutic projects should hold discussions with the reality of users life of and their relationships in the territories of existence, to transform the relations of power and knowledge that reproduce the subjects annulment. Thus, it is possible to dialogue with the complexity of the mental suffering experience, producing changes in the scenes that produce it.

  10. Can the synthetic C view images be used in isolation for diagnosing breast malignancy without reviewing the entire digital breast tomosynthesis data set?

    Murphy, Mark C; Coffey, Louise; O'Neill, Ailbhe C; Quinn, Cecily; Prichard, Ruth; McNally, Sorcha

    2018-02-09

    The aim of this study was to determine if the synthetic C view acquired at digital breast tomosynthesis (DBT) would give adequate information to confirm a malignancy and could obviate the need to review all the tomosynthesis image data set. All patients with biopsy-proven breast cancer recalled from screening mammograms between May and September 2016 were included for review. For each patient, the screening 2D mammogram, the synthetic C view, and the DBT images were reviewed by three breast radiologists and each assigned a BIRADS code. Any discrepancies were reviewed and resolved by consensus. A total of 92 patients were diagnosed with breast cancer in this time period. Fourteen were excluded because they did not have DBT performed. Five women were recalled for evaluation of two lesions. In total, 83 lesions were assessed. In 27 cases, the BIRADS code remained unchanged in the three modalities. In 16 cases, the lesions appeared more concerning on C view and DBT that on the original mammogram but were not definitive for malignancy (BIRADS 4). In 29 cases, a BIRADS 5 code was assigned on C view and tomosynthesis but not on 2D. For 11 lesions, a BIRADS 5 code was assigned only on DBT. Four women had BIRADS 5 lesions seen on both the C view and DBT that were not seen on the screening 2D mammogram. One was multifocal. While the synthetic C view gives additional information when compared to a screening 2D mammogram, the full DBT tomosynthesis data set needs to be reviewed to diagnose a breast malignancy.

  11. Critical thinking of classical view of project management

    祁亮

    2015-01-01

    Synopsis:This essay argues that the classic view has to be updated to meet the new demands. It is found out that the scientific manage-ment believes that there are a few essential roles of managers,including planning,organizing,leading,and controlling. There are many impor-tant aspects which lead to the complexity of the modern project management such as globalization and technology. There are many things that are not compatible between the current projects and the traditional theory. It is also considerable to realize that sometimes scholars disagree with each other about the prevalence of complicated projects. However,even if the classic project management theory is useful in certain cases, there is no doubt that such theory demands significant improvements to better suit the current world. Therefore,it is significant that the classic project management theory be upgraded. In order to improve the performances of the project management,it is recommended that stakeholder theory is promoted,decentralized decision making is allowed,and adoption of new technology is recommended.

    Full Text Available The purpose of this study was to find out the students’views about the innovations brought about by FATIH Project. The research data were collected via field notes, in-class observations made in 10 class hours and focus group interviews held with 45 students participating in the study on voluntary basis from five state schools located in the cities of Ankara, Karaman, Mersin (2 and Uşak. Within the scope of the study the data were analyzed with the content analysis method. It was found out the innovations brought about by FATIH Project led to positive changes in students’ interest and willingness in classes, their achievement levels, their motivations, their pace of learning, their technology use and research skills, permanency in their learning and their self-confidence. The students reported that the negative changes included distraction of students’ attention to classes, limitation in face-to-face communication with the teacher, the slowing pace of teaching, time-taking classes, confidence problems, the teacher’s increasing desire to control students and difficulty in class-management.It was also revealed that use of tablets for a long time resulted in eye diseases and headaches and that the project helped the students instantly reach the information they needed, contributed to their motivation in learning yet had negative influence on their socialization. It was found that the students felt themselves privileged as they were involved in the project; that they were pleased as the classes were taught in a more entertaining manner; and that inefficient content and interaction problems between the interactive whiteboard and tablet computers were considered to be negative consequences of the innovations brought about by the project.

    One of the major aims in the economic management of a nuclear power project is the completion of the project on scheduled time, at preditermined cost and technical performance in accordance with pre-established goals. The achievement of these goals depends, to the major extent, on the adequacy and accuracy of the project plan. The highest possibilities to save money, minimize delivery time, secure good performance are given during the periode of project planning. During project implementation the project management only should direct his activities for the realization of the pre-elaborated project plan. (orig./FW) [de

  15. Application of The Rainfall-runoff Model Topkapi For The Entire Basin of The Po River As Part of The European Project Effs

    Science.gov (United States)

    Todini, E.; Bartholmes, J.

    The project EFFS (European Flood Forecasting System) aims at developing a flood forecasting system for the major river basins all over Europe. To extend the forecast- ing and thus the warning time in a significant way (up to 10 days) meteorological forecasting data from the ECMWF will be used as input to hydrological models. For this purpose it is fundamental to have a reliable rainfall-runoff model. For the river Po basin we chose the TOPKAPI model (Ciarapica, Todini 1998). TOPKAPI is a physi- cally based rainfall-runoff model that maintains its physical significance passing from hillslope to large basin scale. The aim of the distributed version is to reproduce the spatial variability and to lead to a better understanding of scaling effects on meteo- rological data used as well as of physical phenomena and parameters. By now the TOPKAPI model has been applied successfully to basins of smaller and medium size (up to 8000 km2). The present work also proves that TOPKAPI is a valuable flood forecasting tool for larger basins such as the Po river. An advantage of the TOPKAPI model is its physical basis. It doesn't need a "real" calibration in the common sense of the expression. The calibration work that has to be done is due to the unavoidable averaging and approximation in the input data representing various phenomena. This reduces the calibration work as well as the length of data required. The model was implemented on the Po river at spatial steps of 1km and time steps of 1 hour using available data during the year 1994. After the calibration phase, mesoscale forecasts (from ECMWF) as well as forecasts of LAM models (DWD,DMI) will be used as input to the Po river models and their behaviour will be studied as a function of the prediction quality and of the coarseness of the spatial discretisation.

    This paper explores how theories of the planning fallacy and the outside view may be used to conduct quality control and due diligence in project management. First, a much-neglected issue in project management is identified, namely that the front-end estimates of costs and benefits--used in the business cases, cost-benefit analyses, and social and environmental impact assessments that typically support decisions on projects--are typically significantly different from actual ex post costs and ...

  2. Development of a volumetric projection technique for the digital evaluation of field of view.

    Science.gov (United States)

    Marshall, Russell; Summerskill, Stephen; Cook, Sharon

    2013-01-01

    Current regulations for field of view requirements in road vehicles are defined by 2D areas projected on the ground plane. This paper discusses the development of a new software-based volumetric field of view projection tool and its implementation within an existing digital human modelling system. In addition, the exploitation of this new tool is highlighted through its use in a UK Department for Transport funded research project exploring the current concerns with driver vision. Focusing specifically on rearwards visibility in small and medium passenger vehicles, the volumetric approach is shown to provide a number of distinct advantages. The ability to explore multiple projections of both direct vision (through windows) and indirect vision (through mirrors) provides a greater understanding of the field of view environment afforded to the driver whilst still maintaining compatibility with the 2D projections of the regulatory standards. Field of view requirements for drivers of road vehicles are defined by simplified 2D areas projected onto the ground plane. However, driver vision is a complex 3D problem. This paper presents the development of a new software-based 3D volumetric projection technique and its implementation in the evaluation of driver vision in small- and medium-sized passenger vehicles.

  3. ADVERTISEMENTS FOR ICT PROJECT MANAGERS SHOW DIVERSITY BETWEEN SWEDISH EMPLOYERS’ AND PROJECT MANAGEMENT ASSOCIATIONS’ VIEWS OF PM CERTIFICATIONS

    Directory of Open Access Journals (Sweden)

    Siw Lundqvist

    2014-05-01

    Full Text Available Appointing ICT project managers is a delicate issue for management; not least since ICT projects are known to be unsuccessful in delivering the required product in time and on budget. Hence, it is even more important to find the “right” individual for the job. According to project management associations, certification in project management is a prerequisite for a project manager’s successful career. The appreciation of project management certifications among Swedish employers was studied using data collected from job advertisements for ICT project managers during four years (2010-2013. Judged on how the advertisements were worded the result indicates surprisingly low interest from the employers’ side, which conflicts with the project management associations statements about the certifications’ indispensable value for successful projects. Furthermore, it conflicts with a common understanding of certifications as essential for appointment as a project manager. The findings identify a possible gap between PM associations’ and employers’ views regarding the certifications’ value, and highlight the necessity of seriously considering whether it is worthwhile for the individuals to strive for, and for the organizations to promote certification, since it is costly in both time, effort and money.

  5. ANALYSIS OF FORECASTING METHODS FROM THE POINT OF VIEW OF EARLY WARNING CONCEPT IN PROJECT MANAGEMENT

    Directory of Open Access Journals (Sweden)

    Florin POPESCU

    2017-12-01

    Full Text Available Early warning system (EWS based on a reliable forecasting process has become a critical component of the management of large complex industrial projects in the globalized transnational environment. The purpose of this research is to critically analyze the forecasting methods from the point of view of early warning, choosing those useful for the construction of EWS. This research addresses complementary techniques, using Bayesian Networks, which addresses both uncertainties and causality in project planning and execution, with the goal of generating early warning signals for project managers. Even though Bayesian networks have been widely used in a range of decision-support applications, their application as early warning systems for project management is still new.

    2015-05-01

    As one of popular immersive Virtual Reality (VR) systems, stereoscopic cave automatic virtual environment (CAVE) system is typically consisted of 4 to 6 3m-by-3m sides of a room made of rear-projected screens. While many endeavors have been made to reduce the size of the projection-based CAVE system, the issue of asthenopia caused by lengthy exposure to stereoscopic images in such CAVE with a close viewing distance was seldom tangled. In this paper, we propose a light-weighted approach which utilizes a convex eyepiece to reduce visual discomfort induced by stereoscopic vision. An empirical experiment was conducted to examine the feasibility of convex eyepiece in a large depth of field (DOF) at close viewing distance both objectively and subjectively. The result shows the positive effects of convex eyepiece on the relief of eyestrain.

    SeaView is an NSF-funded EarthCube Integrative Activity Project working with 5 existing data repositories* to provide oceanographers with highly integrated thematic data collections in user-requested formats. The project has three complementary goals: Supporting Scientists: SeaView targets scientists' need for easy access to data of interest that are ready to import into their preferred tool. Strengthening Repositories: By integrating data from multiple repositories for science use, SeaView is helping the ocean data repositories align their data and processes and make ocean data more accessible and easily integrated. Informing EarthCube (earthcube.org): SeaView's experience as an integration demonstration can inform the larger NSF EarthCube architecture and design effort. The challenges faced in this small-scale effort are informative to geosciences cyberinfrastructure more generally. Here we focus on the lessons learned that may inform other data facilities and integrative architecture projects. (The SeaView data collections will be presented at the Ocean Sciences 2018 meeting.) One example is the importance of shared semantics, with persistent identifiers, for key integration elements across the data sets (e.g. cruise, parameter, and project/program.) These must allow for revision through time and should have an agreed authority or process for resolving conflicts: aligning identifiers and correcting errors were time consuming and often required both deep domain knowledge and "back end" knowledge of the data facilities. Another example is the need for robust provenance, and tools that support automated or semi-automated data transform pipelines that capture provenance. Multiple copies and versions of data are now flowing into repositories, and onward to long-term archives such as NOAA NCEI and umbrella portals such as DataONE. Exact copies can be identified with hashes (for those that have the skills), but it can be painfully difficult to understand the processing

    This study is to calculate the proper angle for the optimal image of PNS Water's view on children, comparing and analyzing the PNS Water's projection angles between children and adults at every age. This study randomly selected 50 patients who visited the Medical Center from January to May in 2005, and examined the incidence path of central ray, taking a PNS Water's and skull trans-Lat. view in Water's filming position while attaching a lead ball mark on the Orbit, EAM, and acanthion of the patient's skull. And then, we calculated the incidence angles (angle A) of the line connected from OML and the petrous ridge to the inferior margin of maxilla on general (random) patient's skull image, following the incidence path of central ray. Finally, we analyzed two pieces of the graphs at ages, developing out the patient's ideal images at PNS Water's filming position taken by a digital camera, and calculating the angle (angle B) between OML and IP(Image Plate). The angle between OML and IP is about 43 .deg. in 4-years-old children, which is higher than 37 .deg. as age increases the angle decreases, it goes to 37 .deg. around 30 years of age. That is similar result to maxillary growth period. We can get better quality of Water's image for children when taking the PNS Water's view if we change the projection angles, considering maxillary growth for patients in every age stage

    School science students can benefit greatly from participation in student-directed, open-ended scientific inquiry projects. For various possible reasons, however, students tend not to be engaged in such inquiries. Among factors that may limit their opportunities to engage in open-ended inquiries of their design are teachers' conceptions about science. To explore possible relationships between teachers' conceptions about science and the types of inquiry activities in which they engage students, instrumental case studies of five secondary science teachers were developed, using field notes, repertory grids, samples of lesson plans and student activities, and semistructured interviews. Based on constructivist grounded theory analysis, participating teachers' tendencies to promote student-directed, open-ended scientific inquiry projects seemed to correspond with positions about the nature of science to which they indicated adherence. A tendency to encourage and enable students to carry out student-directed, open-ended scientific inquiry projects appeared to be associated with adherence to social constructivist views about science. Teachers who opposed social constructivist views tended to prefer tight control of student knowledge building procedures and conclusions. We suggest that these results can be explained with reference to human psychological factors, including those associated with teachers' self-esteem and their relationships with knowledge-building processes in the discipline of their teaching.

    Certain patients, through projective identification and splitting mechanisms, test the boundaries of the analytic situation. These patients are usually experiencing overwhelming paranoid-schizoid anxieties and view the object as ruthless and persecutory. Using a Kleinian perspective, the author advocates greater analytic flexibility with these difficult patients who seem unable to use the standard analytic environment. The concept of self-disclosure is examined, and the author discusses certain technical situations where self-disclosure may be helpful.(The Journal of Psychotherapy Practice and Research 1999; 8:225–233) PMID:10413442

    Full Text Available This paper provides an outline of how the economic evaluation and selection of road construction projects can be complemented by social evaluation with a view to achieving a more equitable welfare distribution within a developing country. The article commences by elaborating on the general economic benefits that can arise from investment in economically justified road infrastructure. The different classes of non-road-user beneficiaries are idenified and discussed. The operational characteristics of road transport that are conducive to the stimulation of economic activity are identified and described. The present inequality of income distribution in South Africa is dealt with briefly, followed by a discussion and analysis on the use of equity weights in project evaluation to help bring about a more equitable welfare distribution.

    Participation in horticulture and arts may improve wellbeing in those with mental and physical illness. To conduct an in-depth exploration of the views and experience of participants of a primary-care-based horticultural and participatory arts rehabilitation project (Sydenham Garden). Qualitative interview study of a primary-care-based horticultural and participatory arts rehabilitation project in South London. Semi-structured interviews were conducted with 16 participants (referred to as 'coworkers') of Sydenham Garden. Seven were female. Participants were aged between 38 and 91 years and had a range of severe mental and physical health problems; most had depression. The interviews were analysed using constant comparison and thematic analysis. Data were overwhelmingly positive concerning participation. Coworkers considered participation in the project to promote wellbeing by providing purposeful and enjoyable activity and interest, improving mood and self-perceptions, and providing an escape from life's pressures. Being outdoors was considered therapeutic. The most-valued aspect of participation was the social contact derived as a result of it. Many of the coworkers who were interviewed developed transferable skills, including nationally recognised qualifications, which they valued highly. Delivery of horticultural therapy and participatory arts is a feasible model for improving wellbeing in patients in primary care who have serious illness. Longer-term studies are needed to address what happens to people after leaving such projects.

    Chinese stakeholders (131) from 68 key institutions in 27 provinces were consulted in spring 2009 in an online survey of their perceptions of the barriers and opportunities in financing large-scale carbon dioxide capture and storage (CCS) demonstration projects in China. The online survey was supplemented by 31 follow-up face-to-face interviews. The National Development and Reform Commission (NDRC) was widely perceived as the most important institution in authorizing the first commercial-scale CCS demonstration project and authorization was viewed as more similar to that for a power project than a chemicals project. There were disagreements, however, on the appropriate size for a demonstration plant, the type of capture, and the type of storage. Most stakeholders believed that the international image of the Chinese Government could benefit from demonstrating commercial CCS and that such a project could also create advantages for Chinese companies investing in CCS technologies. In more detailed interviews with 16 financial officials, we found striking disagreements over the perceived risks of demonstrating CCS. The rate of return seen as appropriate for financing demonstration projects was split between stakeholders from development banks (who supported a rate of 5-8%) and those from commercial banks (12-20%). The divergence on rate alone could result in as much as a 40% difference in the cost of CO(2) abatement and 56% higher levelized cost of electricity based on a hypothetical case study of a typical 600-MW new build ultrasupercritical pulverized coal-fired (USCPC) power plant. To finance the extra operational costs, there were sharp divisions over which institutions should bear the brunt of financing although, overall, more than half of the support was expected to come from foreign and Chinese governments.

    Basic communication research has identified a major social problem: communicating about cancer from diagnosis through death of a loved one. Over the past decade, an award-winning investigation into how family members talk through cancer on the telephone, based on a corpus of 61 phone calls over a period of 13 months, has been transformed into a theatrical production entitled The Cancer Play. All dialogue in the play is drawn from naturally occurring (transcribed) interactions between family members as they navigate their way through the trials, tribulations, hopes, and triumphs of a cancer journey. This dramatic performance explicitly acknowledges the power of the arts as an exceptional learning tool for extending empirical research, exploring ordinary family life, and exposing the often taken-for-granted conceptions of health and illness. In this study, a Phase I STTR project funded by the National Cancer Institute (NCI), we assess the feasibility of educating and impacting cancer patients, family members, and medical professionals who viewed the play as a live performance and through DVD screenings. Pre- and postperformance questionnaires were administered to solicit audience feedback. Pre-post change scores demonstrate overwhelming and positive impacts for changing opinions about the perceived importance, and attributed significance, of family communication in the midst of cancer. Paired-sample t-tests were conducted on five factor-analyzed indices/indicators-two indices of opinions about cancer and family communication, two indices measuring the importance of key communication activities, and the self-efficacy indicator-and all factors improved significantly (<.001). Informal talkback sessions were also held following the viewings, and selected audience members participated in focus groups. Talkback and focus-group sessions generated equally strong, support responses. Implications of the Phase I study are being applied in Phase II, a currently funded effort to

    The development of satellites and ground systems (and the technologies that support them) is complex and demands a great deal of rigor in the management of both the information it relies upon and the information it generates via the performance of well established processes. To this extent for the past fifteen years Sapienza Consulting has been supporting the European Space Agency (ESA) in the management of this information and provided ESA with ECSS (European Cooperation for Space Standardization) Standards based Project Management (PM), Product Assurance (PA) and Quality Assurance (QA) software applications. In 2009 Sapienza recognised the need to modernize, standardizing and integrate its core ECSS-based software tools into a single yet modularised suite of applications named ECLIPSE aimed at: • Fulfilling a wider range of historical and emerging requirements, • Providing a better experience for users, • Increasing the value of the information it collects and manages • Lowering the cost of ownership and operation • Increasing collaboration within and between space sector organizations • Aiding in the performance of several PM, PA, QA, and configuration management tasks in adherence to ECSS standards. In this paper, Sapienza will first present the toolset, and a rationale for its development, describing and justifying its architecture, and basic modules composition. Having defined the toolset architecture, this paper will address the current status of the individual applications. A compliance assessment will be presented for each module in the toolset with respect to the ECSS standard it addresses. Lastly experience from early industry and Institutional users will be presented.

  4. Age Stereotypes and Self-Views Revisited: Patterns of Internalization and Projection Processes Across the Life Span.

    2017-07-01

    We investigated processes of age stereotype internalization into the self and projection of self-views onto age stereotypes from a life-span perspective, taking age-related differences in the relevance of life domains into account. Age stereotypes and self-views in eight life domains were assessed in a sample of N = 593 persons aged 30-80 years (T1) at two time points that were separated by a 4-year time interval. We estimated cross-lagged projection and internalization effects in multigroup structural equation models. Internalization and projection effects were contingent on age group and life domain: Internalization effects were strongest in the young and middle-aged groups and emerged in the domains family, personality, work, and leisure. Projection effects in different domains were most pronounced for older participants. Our findings suggest that the internalization of age stereotypes is triggered by domain-specific expectations of impending age-related changes and transitions during certain phases of the life span. Projection processes, however, seem to occur in response to changes that have already been experienced by the individual. Our study demonstrates the dynamic interrelation of age stereotypes and self-views across the life course and highlights the importance of a differentiated, life-span perspective for the understanding of these mechanisms. © The Author 2015.

    Purpose: Optimization-based reconstruction has been proposed and investigated for reconstructing CT images from sparse views, as such the radiation dose can be substantially reduced while maintaining acceptable image quality. The investigation has so far focused on reconstruction from evenly distributed sparse views. Recognizing the clinical situations wherein only unevenly sparse views are available, e.g., image guided radiation therapy, CT perfusion and multi-cycle cardiovascular imaging, we investigate the performance of optimization-based image reconstruction from unevenly sparse projection views in this work. Methods: The investigation is carried out using the FORBILD and an anthropomorphic head phantoms. In the study, 82 views, which are evenly sorted out from a full (360°) axial CT scan consisting of 984 views, form sub-scan I. Another 82 views are sorted out in a similar manner to form sub-scan II. As such, a CT scan with sparse (164) views at 1:6 ratio are formed. By shifting the two sub-scans relatively in view angulation, a CT scan with unevenly distributed sparse (164) views at 1:6 ratio are formed. An optimization-based method is implemented to reconstruct images from the unevenly distributed views. By taking the FBP reconstruction from the full scan (984 views) as the reference, the root mean square (RMS) between the reference and the optimization-based reconstruction is used to evaluate the performance quantitatively. Results: In visual inspection, the optimization-based method outperforms the FBP substantially in the reconstruction from unevenly distributed, which are quantitatively verified by the RMS gauged globally and in ROIs in both the FORBILD and anthropomorphic head phantoms. The RMS increases with increasing severity in the uneven angular distribution, especially in the case of anthropomorphic head phantom. Conclusion: The optimization-based image reconstruction can save radiation dose up to 12-fold while providing acceptable image quality

    We display a close relationship between C* and W*-dynamical systems with KMS states on them and entire cyclic cohomology theory. We construct a character form which assigns to each such system (A, α, R) an even entire cyclic cocycle of the subalgebra A of differentiable (with respect to the given automorphism group) elements of A. We argue that the most interesting case is the von Neumann algebra one, where the automorphism group is determined uniquely by the faithful normal state on the algebra (the modular group) and where the character may provide important information about the algebra.

    We introduce a classification of simple, regular, closed symmetric operators with deficiency indices (1, 1) according to a geometric criterion that extends the classical notions of entire operators and entire operators in the generalized sense due to M G Krein. We show that these classes of operators have several distinctive properties, some of them related to the spectra of their canonical self-adjoint extensions. In particular, we provide necessary and sufficient conditions on the spectra of two canonical self-adjoint extensions of an operator for it to belong to one of our classes. Our discussion is based on some recent results in the theory of de Branges spaces. (paper)

    Purpose: To analyze the effects of projection-view (PV) distribution on the contrast and spatial blurring of microcalcifications on the tomosynthesized slices (X-Y plane) and along the depth (Z) direction for the same radiation dose in digital breast tomosynthesis (DBT). Methods: A GE GEN2 prototype DBT system was used for acquisition of DBT scans. The system acquires PV images from 21 angles in 3 deg. increments over a ±30 deg. range. From these acquired PV images, the authors selected six subsets of PV images to simulate DBT of different angular ranges and angular increments. The number of PV images in each subset was fixed at 11 to simulate a constant total dose. These different PV distributions were subjectively divided into three categories: uniform group, nonuniform central group, and nonuniform extreme group with different angular ranges and angular increments. The simultaneous algebraic reconstruction technique (SART) was applied to each subset to reconstruct the DBT slices. A selective diffusion regularization method was employed to suppress noise. The image quality of microcalcifications in the reconstructed DBTs with different PV distributions was compared using the DBT scans of an American College of Radiology phantom and three human subjects. The contrast-to-noise ratio (CNR) and the full width at half maximum (FWHM) of the line profiles of microcalcifications within their in-focus DBT slices (parallel to detector plane) and the FWHMs of the interplane artifact spread function (ASF) in the Z-direction (perpendicular to detector plane) were used as image quality measures. Results: The results indicate that DBT acquired with a large angular range or, for an equal angular range,with a large fraction of PVs at large angles yielded superior ASF with smaller FWHM in the Z-direction. PV distributions with a narrow angular range or a large fraction of PVs at small angles had stronger interplane artifacts. In the X-Y focal planes, the effect of PV

    Full Text Available In this paper, a successful and fruitful joint project will be presented. The project joins participants from 9 countries and from 15 universities. Since it started in 2001, this project entitled “Software Engineering: Computer Science Education and Research Cooperation” helped participants to gain excellent, up to date educational material, apply modern teaching methods, exchange experiences with other participants, and work jointly on the further development of lectures, case-studies, assignments, examination questions, and other necessary elements of a course. Project works under auspices of Stability Pact of South-Eastern Europe, and is supported by DAAD. The project started with the creation of a common beginning course in “Software Engineering”, but over time it grew and the number of other courses was developed. Finished almost completely are the courses in “Object-oriented programming”, “Software Project Management”, “Advanced Compiler Construction”, and “Data Structures and Algorithms”, and some other courses are under development. Aside from the educational collaboration, project members also developed good scientific cooperation, and published several research papers.

    This paper gives an overview of the factors leading to the decision to construct the Heysham 2 and Heysham 2 and Torness AGR using Agency Agreements and the experiences and lessons learnt during their operation. Inevitably some of the factors and problems described in this paper are not unique to Agency Agreements and are generic to project management of large engineering construction projects. The success and failures are therefore not necessarily attributable directly to the Agency arrangements. There are also a number of external factors (such as the national industrial relations climate) which contributed to the project but are not directly dealt with in the paper. (author)

    The present study explores the dramatic projection of one's own views onto those of Jesus among conservative and liberal American Christians. In a large-scale survey, the relevant views that each group attributed to a contemporary Jesus differed almost as much as their own views. Despite such dissonance-reducing projection, however, conservatives acknowledged the relevant discrepancy with regard to “fellowship” issues (e.g., taxation to reduce economic inequality and treatment of immigrants) and liberals acknowledged the relevant discrepancy with regard to “morality” issues (e.g., abortion and gay marriage). However, conservatives also claimed that a contemporary Jesus would be even more conservative than themselves on the former issues whereas liberals claimed that Jesus would be even more liberal than themselves on the latter issues. Further reducing potential dissonance, liberal and conservative Christians differed markedly in the types of issues they claimed to be more central to their faith. A concluding discussion considers the relationship between individual motivational processes and more social processes that may underlie the present findings, as well as implications for contemporary social and political conflict.

    Global warming is expected to drive increasing extreme sea levels (ESLs) and flood risk along the world's coasts. The present contribution aims to present global ESL projections obtained by combining dynamic simulations of all the major ESL components during the present century, considering the latest CMIP5 projections for RCP4.5 and RCP8.5. Baseline values are obtained combining global re-analyses of tides, waves, and storm surges, including the effects of tropical cyclones. The global average RSLR is projected around 20 and 24 cm by the 2050s under RCP4.5 and RCP8.5, respectively and is projected to reach 46 and 67 cm by the year 2100. The largest increases in MSL are projected along the South Pacific, Australia and West Africa, while the smaller RSLR is projected around East North America, and Europe. Contributions from waves and storm surges show a very weak increasing global trend, which becomes statistically significant only towards the end of the century and under RCP8.5. However, for areas like the East China Sea, Sea of Japan, Alaska, East Bering Sea, as well as the Southern Ocean, climate extremes could increase up to 15%. By the end of this century the 100-year event ESL along the world's coastlines will on average increase by 48 cm for RCP4.5 and 75 cm for RCP8.5. The strongest rise is projected along the Southern Ocean exceeding 1 m under RCP8.5 by the end of the century. Increase exceeding 80 cm is projected for East Asia, West North America, East South America, and the North Indian Ocean. Considering always the business as usual and the year 2100, the lowest increase in ESL100 is projected along the East North America and Europe (below 50 cm). The present findings indicate that, under both RCPs, by the year 2050 the present day 100-year event will occur every 5 years along a large part of the tropics, rendering coastal zones exposed to intermittent flood hazard.

  17. Reconstruction of tomographic image from x-ray projections of a few views

    1982-01-01

    Computer tomographs have progressed rapidly, and in the latest high performance types, the photographing time has been shortened to less than 5 sec, but the clear images of hearts have not yet been obtained. The X-ray tomographs used so far irradiate X-ray from many directions and measure the projected data, but by limiting projection direction to a small number, it was planned to shorter the X-ray photographing time and to reduce X-ray exposure as the objective of this study. In this paper, a method is proposed, by which tomographic images are reconstructed from projected data in a small number of direction by generalized inverse matrix penalty method. This method is the calculation method newly devised by the authors for this purpose. It is a kind of the nonlinear planning method added with the restrictive condition using a generalized inverse matrix, and it is characterized by the simple calculation procedure and rapid convergence. Moreover, the effect on reconstructed images when errors are included in projected data was examined. Also, the simple computer simulation to reconstruct tomographic images using the projected data in four directions was performed, and the usefulness of this method was confirmed. It contributes to the development of superhigh speed tomographs in future. (Kako, I.)

    Large screen information displays are defined as dynamic electronic displays that can be viewed by more than one person and are at least 2-feet wide. These large area displays for public viewing provide convenience, entertainment, security, and efficiency to the viewers. There are numerous uses for large screen information displays including those in advertising, transportation, traffic control, conference room presentations, computer aided design, banking, and military command/control. A noticeable characteristic of the large screen display market is the interchangeability of display types. For any given application, the user can usually choose from at least three alternative technologies, and sometimes from many more. Some display types have features that make them suitable for specific applications due to temperature, brightness, power consumption, or other such characteristic. The overall worldwide unit consumption of large screen information displays of all types and for all applications (excluding consumer TV) will increase from 401,109 units in 1995 to 655,797 units in 2002. On a unit consumption basis, applications in business and education represent the largest share of unit consumption over this time period; in 1995, this application represented 69.7% of the total. The market (value of shipments) will grow from DOL3.1 billion in 1995 to DOL3.9 billion in 2002. The market will be dominated by front LCD projectors and LCD overhead projector plates.

    Climate projections produced with CMIP5 and applied by the Intergovernmental Panel on Climate Change (IPCC) in its fifth assessment report indicate that changes in precipitation and temperature are expected to occur throughout Europe in the 21th century, with a likely decrease of water availability in many regions. Besides, water demand is also expected to increase, in link with these expected climate modifications, but also due to socio-economic and demographic changes. In this respect, the use of future freshwater resources may not be sustainable from the current water management perspective. Therefore adaptation strategies will most likely be needed to cope with these evolutions. In this context, the main objective of the ClimAware project (2010-2013 - www.uni-kassel.de/fb14/wasserbau/CLIMAWARE/, a project implemented within the IWRM-NET Funding Initiative) was to analyse the impacts of climate change (CC) on freshwater resources at the continental and regional scales and to identify efficient adaptation strategies to improve water management for various socio-economic sectors. This should contribute to a more effective implementation of the Water Framework Directive (WFD) and its instruments (river basin management plans, programmes of measures). The project developed integrated measures for improved freshwater management under CC constraints. More specifically, the objectives of the ClimAware project were to: • elaborate quantitative projections of changes in river flows and consequences such as flood frequency, drought occurrence and sectorial water uses. • analyse the effect of CC on the hydromorphological reference conditions of rivers and therefore the definition of "good status". • define management rules/strategies concerning dam management and irrigation practices on different time perspectives. • investigate uncertainties in climate model - scenario combinations. The research approach considered both European and regional perspectives, to get

    The offshore development by Esso/BHP of the West Kingfish, Cobia, Fortescue and Flounder oil fields in the Gippsland Basin is one of the significant undertakings by the petroleum industry during the 1980s. Production from the fields will help sustain the current level of production from Bass Strait into the latter part of this decade. This paper examines some of the principal project management issues and actions involved in the planning and execution of the design and construction phases of the platforms and pipelines associated with each of these fields.

    The purpose of this study is to analyze the perception of the content of health technology assessment (HTA) among health professionals applying for a state grant of DKK 10 million. A total of 113 applications were received and analyzed. When conducting the analysis, it was assumed that the applicants' maximum five-page project description would reflect: a) the applicants' perception of what an HTA is; b) how the assessment was to be conducted; and c) what the results were going to be used for. More than 40% of all applications focused on treatment; in 51% only one or two professional groups were to be involved (thus interdisciplinarity was questionable); only 22% of the HTA cases were intended to form the basis for political/administrative decisions; in general, the HTAs were planned far less comprehensively than was relevant; 76% of the projects did not include a formal synthesis phase; 41% intended to use diffusion as the only method for publication of the HTA result. The analysis reveals several areas where DIHTA has to make an effort in order to secure that HTA in fact constitutes a comprehensive and well-documented basis for decision making. These areas concern the following topics: multidisciplinarity, the objective of HTA, comprehensiveness, the synthesis phase, and publication and utilization of the HTA result.

    The development of the Chaîne des Puys and Limagne Fault World Heritage UNESCO project has taken about five years, since the Laboratoire Magmas et Volcans was approached by the local Auvergne government. Before this we had been working locally with organisations such as the Lemptégy volcano and Vulcania to help disseminate geoscience ideas to the general public, however the UNESCO project has lead us to do much more outreach. It has also stimulated our research and has taught us to better explain this to the lay person. In visiting other heritage projects, where we have exchanged ideas and best practice, we have been able to help other sites and improve what we do. These links are particularly important, as they can be used to help broaden the outlook of the general public and local actors, and increase further earth science literacy. I have noticed a strong increase in the awareness of the volcanoes, and volcanism as a result of the Chaîne des Puys and Limagne Fault project. I think that, before, many locals considered the volcanoes only as their special back garden, for easy walks and views and leisure, or for that matter farming, mining and hunting. However, now, there is a greater sense of pride rooted in the increased awareness of their geological significance in a historical and global context. While this effect is clear for the volcanoes, it is not yet apparent for the fault. The lay person has no clear concept of a rift and a fault. Thus, one of our major present challenges is to open the public's eyes to the fault. This is vital for the UNESCO project not only for educational reasons, but also because the fault scarp is a natural barrier that protects the rest of the property from urban development. Only if there is awareness of its nature and significance will it be an effective defence. To arrive at this goal, there is now a local government sponsored project to create and disseminate fault walks, fault viewpoints and fault information points. This is

    1985-01-01

    Fundamental studies have been made on the application of mathematical programming to the reconstruction of tomographic images from projections of a small number of views without requiring any circular symmetry nor periodicity. Linear programming and quadratic programming were applied to minimize the quadratic sum of the residue and to finally obtain optimized reconstruction images. The mathematical algorithms were verified by the method of computer simulation, and the relationship between the number of picture elements and the number of iterations necessary for convergence was also investigated. The methods of linear programming and quadratic programming require fairly simple mathematical procedures, and strict solutions can be obtained within a finite number of iterations. Their only draw back is the requirement of a large quantity of computer memory. But this problem will be desolved by the advent of large fast memory devices in the near future. (Aoki, K.)

  9. Developing noise control strategies for entire railway networks

    The EU Environmental Noise Directive (2002/49) requires member states to deliver noise maps to the commission by 2007 and action plans by 2008 both for agglomerations as well as for major roads, railways and airports. Noise mitigation projects resulting from action plans are usually very expensive and therefore may threaten the economic viability of the railways in the current harsh competitive transport market, thus hindering sustainable transport policies. It is therefore of vital interest that the action plans and the resulting projects are designed in the most cost-effective way possible. The EU and Union of Railways (UIC) sponsored project Strategies and Tools to Assess and Implement noise Reducing measures for Railway Systems (STAIRRS) recognized this need and developed a tool, with which such optimal solutions can be obtained for entire railway networks. Since data collection is the most expensive part of the analysis, noise mapping data is ideally collected in such a way that it can be used for the calculation of the different scenarios, from which the most cost-effective action plans are chosen. The paper shows how the STAIRRS tool is used for this purpose and how cost-effectiveness considerations have led to optimal railway noise mitigation strategies in Switzerland and have given a basis for noise related decision making in Luxembourg.

The type of this research was qualitative which was descriptive. To obtained the validity of the qualitative data, the checking technique used in this research was sources triangulation, which had been done by comparing the suitability of the obtained data from the results of the interview and the test. Population of this research was the students of grade VIII at SMP Negeri 1 Sidoharjo and the sample was the students from VIII A Class. At the final, 12 research subjects were chosen to represent the group of level 1 self-efficacy, level 2 self-efficacy, level 3 self-efficacy, level 4 self efficacy, level 5 self-efficacy, and level 6 self-efficacy. In this research, there was a finding which shows us that the students with high self-efficacy had low ability to finish the geometrical reasoning ability test, while the students with low self-efficacy had the ability to finish the geometrical reasoning ability test. The factors which affected the finding were the motivations and the interest of learning mathematics which was affecting the attitude of the students in the classroom.

  11. Enhancing multi-view autostereoscopic displays by viewing distance control (VDC)

    Conventional multi-view displays spatially interlace various views of a 3D scene and form appropriate viewing channels. However, they only support sufficient stereo quality within a limited range around the nominal viewing distance (NVD). If this distance is maintained, two slightly divergent views are projected to the person's eyes, both covering the entire screen. With increasing deviations from the NVD the stereo image quality decreases. As a major drawback in usability, the manufacturer so far assigns this distance. We propose a software-based solution that corrects false view assignments depending on the distance of the viewer. Our novel approach enables continuous view adaptation based on the calculation of intermediate views and a column-bycolumn rendering method. The algorithm controls each individual subpixel and generates a new interleaving pattern from selected views. In addition, we use color-coded test content to verify its efficacy. This novel technology helps shifting the physically determined NVD to a user-defined distance thereby supporting stereopsis. The recent viewing positions can fall in front or behind the NVD of the original setup. Our algorithm can be applied to all multi-view autostereoscopic displays — independent of the ascent or the periodicity of the optical element. In general, the viewing distance can be corrected with a factor of more than 2.5. By creating a continuous viewing area the visualized 3D content is suitable even for persons with largely divergent intraocular distance — adults and children alike — without any deficiency in spatial perception.

    Purpose: To investigate the feasibility of a new two-dimensional (2D) multichannel response (MCR) analysis approach for the detection of clustered microcalcifications (MCs) in digital breast tomosynthesis (DBT). Methods: With IRB approval and informed consent, a data set of two-view DBTs from 42 breasts containing biopsy-proven MC clusters was collected in this study. The authors developed a 2D approach for MC detection using projection view (PV) images rather than the reconstructed three-dimensional (3D) DBT volume. Signal-to-noise ratio (SNR) enhancement processing was first applied to each PV to enhance the potential MCs. The locations of MC candidates were then identified with iterative thresholding. The individual MCs were decomposed with Hermite–Gaussian (HG) and Laguerre–Gaussian (LG) basis functions and the channelized Hotelling model was trained to produce the MCRs for each MC on the 2D images. The MCRs from the PVs were fused in 3D by a coincidence counting method that backprojects the MC candidates on the PVs and traces the coincidence of their ray paths in 3D. The 3D MCR was used to differentiate the true MCs from false positives (FPs). Finally a dynamic clustering method was used to identify the potential MC clusters in the DBT volume based on the fact that true MCs of clinical significance appear in clusters. Using two-fold cross validation, the performance of the 3D MCR for classification of true and false MCs was estimated by the area under the receiver operating characteristic (ROC) curve and the overall performance of the MCR approach for detection of clustered MCs was assessed by free response receiver operating characteristic (FROC) analysis. Results: When the HG basis function was used for MCR analysis, the detection of MC cluster achieved case-based test sensitivities of 80% and 90% at the average FP rates of 0.65 and 1.55 FPs per DBT volume, respectively. With LG basis function, the average FP rates were 0.62 and 1.57 per DBT volume at

    This study is part of a first study of collaborative socio-environmental projects that engage Jewish and Arab students in Israel in learning about their local environment and about each other through outdoor learning and environmental action. We used ideas of social learning and environmental citizenship to frame our research. We investigated students' knowledge regarding their local environment and their knowledge of each other's community. We also studied the participants' views regarding their project-partners'environmental knowledge, awareness and behaviour in comparison to their own. Initially, differences were found regarding various aspects of the students' socio-environmental knowledge and in students' views of their counterparts' environmentalism. At the end of the projects, students showed better understanding of local socio-environmental issues and demonstrated changes in their original views towards the environmental awareness and behaviour of their counterparts. These findings suggest that projects which involve students from segregated communities not only promote environmental awareness but contribute to a reduction in mutual prejudices. We suggest that the differences we found are not related to ethnicity, but rather to students' socioeconomic status and experience in environmental education programmes.

    In digital breast tomosynthesis (DBT), quasi-three-dimensional (3D) structural information is reconstructed from a small number of 2D projection view (PV) mammograms acquired over a limited angular range. The authors developed preliminary computer-aided diagnosis (CADx) methods for classification of malignant and benign masses and compared the effectiveness of analyzing lesion characteristics in the reconstructed DBT slices and in the PVs. A data set of MLO view DBT of 99 patients containing 107 masses (56 malignant and 51 benign) was collected at the Massachusetts General Hospital with IRB approval. The DBTs were obtained with a GE prototype system which acquired 11 PVs over a 50 degree arc. The authors reconstructed the DBTs at 1 mm slice interval using a simultaneous algebraic reconstruction technique. The region of interest (ROI) containing the mass was marked by a radiologist in the DBT volume and the corresponding ROIs on the PVs were derived based on the imaging geometry. The subsequent processes were fully automated. For classification of masses using the DBT-slice approach, the mass on each slice was segmented by an active contour model initialized with adaptive k-means clustering. A spiculation likelihood map was generated by analysis of the gradient directions around the mass margin and spiculation features were extracted from the map. The rubber band straightening transform (RBST) was applied to a band of pixels around the segmented mass boundary. The RBST image was enhanced by Sobel filtering in the horizontal and vertical directions, from which run-length statistics texture features were extracted. Morphological features including those from the normalized radial length were designed to describe the mass shape.

    Conventional PET scanners can image the whole body using many bed positions. On the other hand, an entire-body PET scanner with an extended axial FOV, which can trace whole-body uptake images at the same time and improve sensitivity dynamically, has been desired. The entire-body PET scanner would have to process a large amount of data effectively. As a result, the entire-body PET scanner has high dead time at a multiplex detector grouping process. Also, the entire-body PET scanner has many oblique line-of-responses. In this work, we study an efficient data acquisition for the entire-body PET scanner using the Monte Carlo simulation. The simulated entire-body PET scanner based on depth-of-interaction detectors has a 2016-mm axial field-of-view (FOV) and an 80-cm ring diameter. Since the entire-body PET scanner has higher single data loss than a conventional PET scanner at grouping circuits, the NECR of the entire-body PET scanner decreases. But, single data loss is mitigated by separating the axially arranged detector into multiple parts. Our choice of 3 groups of axially-arranged detectors has shown to increase the peak NECR by 41%. An appropriate choice of maximum ring difference (MRD) will also maintain the same high performance of sensitivity and high peak NECR while at the same time reduces the data size. The extremely-oblique line of response for large axial FOV does not contribute much to the performance of the scanner. The total sensitivity with full MRD increased only 15% than that with about half MRD. The peak NECR was saturated at about half MRD. The entire-body PET scanner promises to provide a large axial FOV and to have sufficient performance values without using the full data.

    Full Text Available Aim of the study is to assess how students in 6th, 7th and 8th grades of primary education see the project works made in science education and their implementation processes. The study was fulfilled upon the descriptive survey model to collect data. Participants of the research were 100 students who had project implementation experiences in science education, and they were from 24 primary schools in 7 districts randomly chosen in the city of Istanbul in Turkey. Data of the study were collected by using a semi-constructed interview form offered to students during the 2005-2006 teaching year. In the research, following items were examined: The extent to which students are inspired from the previously made projects during their own project selection process, the level of scientific document survey and the effects of contemporary events, science and technology class topics and students’ interest areas. It was seen that internet is the mostly used source to obtain information. For students, one of the most problematic issues faced during the project implementation is the time limits set out by teacher. It was found that the most obvious benefit obtained by students from the project works is their increasing interest towards science and technology class. The most significant change seen by students regarding project preparation is their increasing grades in exams during and following the project works.

    Full Text Available Data collection or generation is the primary way that the majority of volunteers advance the scientific goals of citizen science projects, but other activities such as data consumption also may influence learning, civic, and conservation outcomes. Project designers and managers balance goals for multiple outcomes and thus need to consider the influence of all project-related activities on outcomes. In a study of the kayak-based Citizen’s Water Quality Testing (CWQT Program in New York City, we compared the characteristics, perceptions, and behaviors of those collecting and using CWQT data (data collectors and those solely using the data (data consumers. Data collectors (n = 40 and consumers (n = 24 were similar in gender and political orientation, but collectors were younger, devoted more time to the project, and experienced far more face-to-face interactions related to the project. Data collectors and consumers had similar motivations for participation, except that collectors were more likely motivated by recognition for their efforts. Lack of free time was the largest barrier to participation for both types of participants, and a significantly greater barrier for consumers. Data collectors and consumers trusted volunteer-collected data more than government-collected data. Collectors and consumers both recognized multiple scientific, environmental, and social benefits associated with the project, and both were equally likely to use volunteer-collected data for a variety of purposes, such as informing decisions about conservation and recreation. Importantly, both groups were equally likely to undertake a suite of conservation behaviors. We synthesize and expand current conceptual frameworks of citizen science participation and outcomes, highlighting the need for further study to understand mechanisms and linkages between the varied activities of citizen science projects and broader social and ecological impacts.

    A conventional PET scanner has a 15-25 cm axial field-of-view (FOV) and images a whole body using about six bed positions. An OpenPET geometry can extend the axial FOV with a limited number of detectors. The entire whole-body PET scanner must be able to process a large amount of data effectively. In this work, we study feasibility of the fully 3D entire whole-body PET scanner using the GATE simulation. The OpenPET has 12 block detector rings with the ring diameter of 840 mm and each block detector ring consists of 48 depth-of-interaction (DOI) detectors. The OpenPET has the axial length of 895.95 mm with five parts of 58.95 mm open gaps. The OpenPET has higher single data loss than a conventional PET scanner at grouping circuits. NECR of the OpenPET decreases by single data loss. But single data loss is mitigated by separating the axially arranged detector into two parts. Also, multiple coincidences are found to be important for the entire whole-body PET scanner. The entire whole-body PET scanner with the OpenPET geometry promises to provide a large axial FOV with the open space and to have sufficient performance values. But single data loss at the grouping circuits and multiple coincidences are limited to the peak noise equivalent count rate (NECR) for the entire whole-body PET scanner.

    ENGLISH ABSTRACT: Transnet Freight Rail in South Africa has faced projects delays in its multi-project environment. This study takes South Africa as representative of developing countries, and develops the Critical Success Factors (CSFs model for multiple projects success, with the goal of expanding the conventional model by adding the demographic characteristics of the business units involved in the multiple projects. The empirical results showing the greatest number of success factors are people-related, with the focus on team selection and team commitment. Two demographic characteristics are of importance when managing multiple projects: the size of the business unit, and the employees’ project experience.

    AFRIKAANSE OPSOMMING: Transnet, ‘n spoorvragentiteit in Suid-Afrika, ondervind gereeld projekvertragings in hul multi-projekomgewing. Suid-Afrika, as ‘n voorbeeld van ontwikkelende lande, word in die studie gebruik en hierdie studie ontwikkel ‘n reeks suksesfaktore vir ‘n multi-projek-omgewing deur ‘n bestaande konvensionele model aan te pas om ook die demografiese eienskappe van die verskillende besigheidseenhede betrokke in die organisasie te inkorpo-reer. Die resultaat van die studie wys dat die grootste aantal suksesfaktore mens-geörienteerd is, met die fokus op die samestelling en toewyding van die betrokke projekspanne. Twee demografiese eienskape is belangrik by die bestuur van multi-projekte, naamlik die grootte van die besigheidseenheid asook projekondervinding van die werknemers.

  9. Assessment of highway infrastructure projects in Latin America and Perú from the competences point of view

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available It is stressed that Latin America and Peru should become more competitive. Under the actual development scenarios, attention to competences of programme managers and project managers related to public transportation infrastructure projects has risen substantially. An inefficient bureaucratic system is related with deficiencies of people skills and competences. On the other hand, an excellent system demands quality of the system and quality of people working in it. Thus, it is important to have excellence in administration and excellent administrators in the public sector. Three main lacking elements have been identified: i lack of good education; ii absence of fair salaries in the public sector; and iii lack of incentives. Many misconceptions and disputed consequences have been observed and analyzed. It is clear that there is lack of competence among infrastructure transport project managers and teams, which causes trouble with the main goal of Peru getting benefits from these investments and achieving sustainable development. Furthermore, the right way to achieve these benefits is through a new model of education for project managers and programme managers in Peru. This education should be based more on competences than on qualifications. Thus, the International Project Management Association (IPMA competence baseline, which is the standard that best fits to these needs, needs to be implemented to achieve the real contribution and benefits of these projects to society.

  10. Pade approximants for entire functions with regularly decreasing Taylor coefficients

    International Nuclear Information System (INIS)

    Rusak, V N; Starovoitov, A P

    2002-01-01

    For a class of entire functions the asymptotic behaviour of the Hadamard determinants D n,m as 0≤m≤m(n)→∞ and n→∞ is described. This enables one to study the behaviour of parabolic sequences from Pade and Chebyshev tables for many individual entire functions. The central result of the paper is as follows: for some sequences {(n,m(n))} in certain classes of entire functions (with regular Taylor coefficients) the Pade approximants {π n,m(n) }, which provide the locally best possible rational approximations, converge to the given function uniformly on the compact set D={z:|z|≤1} with asymptotically best rate

    2013-01-01

    In the video of linear CCD camera being irradiated by 532 nm CW laser, the entirely saturated unilateral smear of laser spot was found. The smear area does not represent the distribution of laser. Since this smear lies merely in one side of laser spot, it can not be induced by light leaking or carriers blooming, and it may be induced by charge transfer loss. However, the feature that the smear area is entirely saturated can not be explained by the current constant model of charge transfer inefficiency. Based on the inner structure and operating principle of buried channel CCD, a new model of charge transfer inefficiency that varies with charge quantity is proposed, which can explain the entirely saturated unilateral smear of laser spot.

  12. Entirely irrelevant distractors can capture and captivate attention.

    2011-12-01

    The question of whether a stimulus onset may capture attention when it is entirely irrelevant to the task and even in the absence of any attentional settings for abrupt onset or any dynamic changes has been highly controversial. In the present study, we designed a novel irrelevant capture task to address this question. Participants engaged in a continuous task making sequential forced choice (letter or digit) responses to each item in an alphanumeric matrix that remained on screen throughout many responses. This task therefore involved no attentional settings for onset or indeed any dynamic changes, yet the brief onset of an entirely irrelevant distractor (a cartoon picture) resulted in significant slowing of the two (Experiment 1) or three (Experiment 2) responses immediately following distractor appearance These findings provide a clear demonstration of attention being captured and captivated by a distractor that is entirely irrelevant to any attentional settings of the task.

  15. Using Project-Based Data in Physics to Examine Television Viewing in Relation to Student Performance in Science

    Science.gov (United States)

    Espinoza, Fernando

    2009-10-01

    Mass media, particularly television, influence public conceptions and attitudes toward learning science. The discovery of an original method that does not rely on self-reported viewing habits to measure the impact of television on students' performance in science arose from a study of a unit on electricity in a Physics course. In determining the number of television sets at home and the number of hours of operation, data emerged that allowed an investigation of associations between each of these variables and student performance in physics. A negative impact on performance was found in its consistent decrease as both the number of sets and the time the sets are on increase. These results provide dramatic independent confirmation of the negative impact of television viewing on achievement determined through meta-analysis of many studies, and are also consistent with those in the literature at large, particularly from the Third International Mathematics and Science Study, and the National Assessment of Educational Progress. Furthermore, the totally `blind' participation of the subjects lends a degree of authenticity rarely found in a classically designed study. The findings impact scientific literacy, since performance in science and conceptions of science and scientists, are all inextricably linked.

  18. The JSpecView Project: an Open Source Java viewer and converter for JCAMP-DX, and XML spectral data files

    Directory of Open Access Journals (Sweden)

    Lancashire Robert J

    2007-12-01

    Full Text Available Abstract The JSpecView Open Source project began with the intention of providing both a teaching and research tool for the display of JCAMP-DX spectra. The development of the Java source code commenced under license in 2001 and was released as Open Source in March 2006. The scope was then broadened to take advantage of the XML initiative in Chemistry and routines to read and write AnIML and CMLspect documents were added. JSpecView has the ability to display the full range of JCAMP-DX formats and protocols and to display multiple spectra simultaneously. As an aid for the interpretation of spectra it was found useful to offer routines such that if any part of the spectral display is clicked, that region can be highlighted and the (x, y coordinates returned. This is conveniently handled using calls from JavaScript and the feedback results can be used to initiate links to other applets like Jmol, to generate a peak table, or even to load audio clips providing helpful hints. Whilst the current user base is still small, there are a number of sites that already feature the applet. A tutorial video showing how to examine NMR spectra using JSpecView has appeared on YouTube and was formatted for replay on iPods and it has been incorporated into a chemistry search engine.

  19. Entire hemithorax irradiation for Masaoka stage IVa thymomas

    Soares, André; Louro, Luís Vasco; Almeida, Marta; Sousa, Olga

    2012-01-01

    Thymomas are rare neoplasms that have an indolent growth with a preferentially intra-thoracic dissemination pattern. Surgery is currently the standard treatment of thymomas; however radiotherapy is often used in an adjuvant setting due to a high sensitivity of these tumors to such treatment. Postoperative entire hemithoracic irradiation has been used in selected Masaoka stage IVa cases after complete surgical excision of metastatic lesions. In the present article, the authors report three cases of Masaoka stage IVa thymoma that underwent entire hemithorax irradiation after surgical excision of metastatic lesions. The first two patients presented as stage IVa thymomas. The third case consisted of a pleural recurrence of a thymoma. Hemithoracic irradiation with low doses has been used by different authors; the available data shows that it is a well-tolerated treatment that could potentially lead to better loco-regional control and increased overall survival.

    We have developed new sample preparation and analytical techniques tailored for entire aerogel tracks of Wild 2 sample analyses both on "carrot" and "bulbous" tracks. We have successfully ultramicrotomed an entire track along its axis while preserving its original shape. This innovation allowed us to examine the distribution of fragments along the entire track from the entrance hole all the way to the terminal particle. The crystalline silicates we measured have Mg-rich compositions and O isotopic compositions in the range of meteoritic materials, implying that they originated in the inner solar system. The terminal particle of the carrot track is a 16O-rich forsteritic grain that may have formed in a similar environment as Ca-, Al-rich inclusions and amoeboid olivine aggregates in primitive carbonaceous chondrites. The track also contains submicron-sized diamond grains likely formed in the solar system. Complex aromatic hydrocarbons distributed along aerogel tracks and in terminal particles. These organics are likely cometary but affected by shock heating.

  7. A Case Study of Framing and Project Design Impacts on Participant Identity, Views, and Trust of Science in a Phenology Public Participatory Program

    Science.gov (United States)

    Sorensen, A. E.; Jordan, R.

    2016-12-01

    Recent literature has suggested public participatory research models (e.g., citizen science and similar) as a key opportunity for scientists to meaningfully engage and communicate with the public to increase support for science and encourage pro-science behavior. In this, there has been an inherent assumption that all models of engagement yield similar participant results with few examples of assessment of these programs. While many of these programs do share superficial similarities in their modes of participant engagement and participant motivation, there is a large disparity in participant engagement between them. This disparity suggests that framing of these projects (e.g., citizen science versus crowd sourcing) also plays an important role in decisions about participation. Additionally, participant outcomes, in terms of beliefs about scientific practices and scientific trust, between these two project types has not yet been investigated. To investigate the impact of framing, participants were recruited to a web-based tree phenology public participatory research program where half the participants were engaged in a citizen science framed program and the other were engaged in a crowdsourced framed project. The participants in each frame were engaged in the same task (reporting leaf budding/leaf drop), but the way the projects were framed differed. Post-participation we see that there are indeed statistically significant differences in participant outcomes between individuals who participated as a citizen scientist versus as a crowdsourcer. Particularly we see differences in terms of their views of science, identity, and trust of science. This work is the first to the authors' knowledge that aims to evaluate if projects can be treated synonymously when discussing potential for public engagement and broader trust and literacy outcomes.

    CNC cutting machines have become essential tools for designers and architects enabling rapid prototyping, model-building and production of high quality components. Designers often cut from new materials, discarding the irregularly shaped remains. We introduce ProjecTables, a visual augmented...... reality system for interactive packing of model parts onto sheet materials. ProjecTables enables designers to (re)use scrap materials for CNC cutting that would have been previously thrown away, at the same time supporting aesthetic choices related to wood grain, avoiding surface blemishes, and other...... relevant material properties. We conducted evaluations of ProjecTables with design students from Aarhus School of Architecture, demonstrating that participants could quickly and easily place and orient model parts reducing material waste.

    In 1981 the linear accelerator 'Neptun 10 p' will be mounted at the Radiological Clinic of the University of Greifswald. Its place will be an irradiation room which is equipped for a radiation of 1.33 MeV. The strengthening of walls and celling, which is necessary for 9 MeV bremsstrahlung and 10 MeV electron radiation, can only be realized by a self-supporting lead-steel construction for reasons of the distance to the neighbouring house and of the connected conditions of foundation as well as of the load capacity of the existing construction of the roof. As in the eighties similar problems are to be expected in other radiological hospitals of the GDR the constructive solution of the Greifswald linear accelerator project and connected problems of the radiation protection are represented.

Findings demonstrated that high proportions of the respondents had positive perceptions of the program and the instructors, and roughly four-fifths of the respondents regarded the program as beneficial to them. Correlation analyses showed that perceived program and instructor characteristics were positively associated with perceived benefits of the program.

  11. Requirements for effective technology transfer for engineering and project management. The views of the recipient country and the technology supplier

    International Nuclear Information System (INIS)

    Backhaus, K.W.

    1986-04-01

    Technology transfer in the area of engineering and project management for nuclear power plant projects is considered a rather complex and sophisticated matter. Therefore only within a long-term nuclear co-operation a meaningful transfer of such a multifaceted technology can reasonably be achieved. A long-term nuclear co-operation anticipates a nuclear power plant program consisting of a few nuclear power plants of a certain type and size in order to achieve the indispensable effect ''learning by doing''. The objectives of nuclear technology transfer may be in general or in particular; absorption of a foreign nuclear technology and its adaptation to the conditions and needs of the receiver's country; built-up of industrial infrastructure for planning, construction and operation of nuclear power plants; raising of the general industrial level and achieve a spin-off effect; creation of a basis for independent development of nuclear technology. The technology transfer on one side and the construction program of nuclear power plants on the other side cannot be practiced by two parallel but separated event, however, they form one unit. Contrary to the import of industrial equipment in terms of ''black box'', by means of a nuclear technology transfer the introduction of new dependencies will be prevented. The technology transfer can remarkably be facilitated by forming a joint venture engineering company in the recipient country. The required know-how potential within a certain time period determines the intensity of the technology transfer and consequently the man power to be involved. The realization of such technology transfer is demonstrated by means of practical examples. (author). 12 figs

    1983-01-01

    Diverticulum is considered as a common lesion involving any gastrointestinal tract from the pharynx to the rectum. We reviewed 5,806 cases of upper G-I series and 801 cases of double contrast barium enema during the period from Jan.1978 to Dec. 1981 in the Department of Radiology, School of Medicine, Jeonbug National University Hospital to analyze diverticula of the entire gastrointestinal tract. The results were as follows: 1. Roentgen examination of 5,806 esophagus, stomachs, duodenums and small bowels, and 801 colons during the past four years: diverticula of the esophagus, 60 cases (1.0%); diverticula of the stomach, 42 cases (0.7%); diverticula of the duodenum, 358 cases (6.2%); diverticula of the small bowel, 20 cases (0.3%); diverticula of the colon, 26 cases (3.2%). The location of diverticula in order of frequency was duodenum, colon, esophagus, stomach and small bowel. 2. The most common site of diverticula of each gastrointestinal tract was as follows: diverticula of the esophagus, middle portion (84.7%); diverticula of the stomach, the cardia (59.5%); diverticula of the duodenum, the second portion (81.3%); diverticula of the small bowel, the jejunum (96.4%)-especially the larger percentage were observed at the upper jejunum near the ligament of Treitz; diverticula of the colon, the right sided colon (80.8%)-the cecum and ascending colon (57.1%). 3. Diverticula may occur at any age. The majority of diverticula of the entire gastrointestinal tract were observed over 40 years of age. Especially in diverticula of the duodenum and colon, their frequency increase with age. 4. Duodenal diverticula were observed more frequently in woman than in man but in diverticula of the esophagus, stomach, small bowel and colon, male was more frequently affected. 5. The size of diverticula of the entire gastrointestinal tract was variable. The majority of diverticula of the esophagus, stomach, duodenum and small bowel were intermediate in size (10-49 mm).

    Dietzel, Anne; Rahn, Eric; Stamm, Christian

    2014-05-01

    Swiss agriculture is legally committed to fulfill several, partially conflicting goals such as agricultural production on the one hand and the conservation of natural resources on the other hand. In the context of the research project AProWa ("Agricultural Production and Water"), the relationships between the production aspect and the conservation of aquatic ecosystems is analyzed with a holistic approach. Agricultural production and the protection of water resources have high potential for conflicts: Farmers use ground and surface water to irrigate their fields. On the other hand, drainage systems enable the production on otherwise unfavorably wet soils. These in turn often affect ground water recharge and divert precipitation directly into surface waters, which changes their hydrological regime. Typically, drainage systems also elevate the input of nutrients and pesticides into the water bodies. In general, applied fertilizers, plant protection products, veterinary drugs and phytohormones of cultivated plants are introduced into the ground and surface waters through different processes such as drift, leaching, runoff, preferential flow or erosion. They influence the nutrient cycles and ecological health of aquatic systems. The nutrient and pesticide loss processes themselves can be altered by tillage operations and other agricultural practices. Furthermore, the competition for space can lead to additional conflicts between agriculture and the protection of aquatic ecosystems. For example, channelized or otherwise morphologically changed rivers do not have a natural discharge pattern and are often not suitable for the local flora and fauna; but naturally meandering rivers need space that cannot be used for agriculture. In a highly industrialized and densely populated country like Switzerland, all these potential conflicts are of importance. Although it is typically seen as a water-rich country, local and seasonal overexploitation of rivers through water extraction

    1997-04-01

    When a molecule is adsorbed on a metal surface by chemical bonding new electronic states are formed. For noble and transition metals these adsorption-induced states overlap with the much more intense metal d-valence band, making them difficult to probe by for instance direct photoemission. However, it has recently been shown that X-ray emission spectroscopy (XES) can be applied to adsorbate systems. Since the intermediate state involves a core hole, this technique has the power to project out the partial density of states around each atomic site. Both the excitation and deexcitation processes are in general governed by the dipole selection rules. For oriented system, it is hence possible to obtain a complete separation into 2p{sub x}, 2p{sub y} and 2p{sub z} contributions using angular resolved measurements. The authors have applied XES together with other core level spectroscopies to glycine adsorption on Cu(110). Glycine (NH{sub 2}CH{sub 2}COOH) is the smallest amino acid and very suitable to study by core level spectroscopy since it has several functional groups, all well separated in energy by chemical shifts. Its properties are futhermore of biological interest. In summary, the authors have shown that it is possible to apply XES to more complicated molecular adsorbates. The assignment of different electronic states is however not as straight forward as for simple diatomic molecules. For a complete understanding of the redistribution and formation of new electronic states associated with the surface chemical bond, experimental data must be compared to theoretical calculations.

    An individual's health, genetic, or environmental-exposure data, placed in an online repository, creates a valuable shared resource that can accelerate biomedical research and even open opportunities for crowd-sourcing discoveries by members of the public. But these data become "immortalized" in ways that may create lasting risk as well as benefit. Once shared on the Internet, the data are difficult or impossible to redact, and identities may be revealed by a process called data linkage, in which online data sets are matched to each other. Reidentification (re-ID), the process of associating an individual's name with data that were considered deidentified, poses risks such as insurance or employment discrimination, social stigma, and breach of the promises often made in informed-consent documents. At the same time, re-ID poses risks to researchers and indeed to the future of science, should re-ID end up undermining the trust and participation of potential research participants. The ethical challenges of online data sharing are heightened as so-called big data becomes an increasingly important research tool and driver of new research structures. Big data is shifting research to include large numbers of researchers and institutions as well as large numbers of participants providing diverse types of data, so the participants' consent relationship is no longer with a person or even a research institution. In addition, consent is further transformed because big data analysis often begins with descriptive inquiry and generation of a hypothesis, and the research questions cannot be clearly defined at the outset and may be unforeseeable over the long term. In this article, we consider how expanded data sharing poses new challenges, illustrated by genomics and the transition to new models of consent. We draw on the experiences of participants in an open data platform-the Personal Genome Project-to allow study participants to contribute their voices to inform ethical consent

    To generate a smooth implicit function that behaves naturally over an entire domain, a method to smoothly combine an implicit function f(x) with a global support function g(x) has been proposed. The proposed method can be applied to large scattered point data, since the implicit function f(x) is generated by a partition-of-unity-based method. The global support function g(x) is generated by a radial basis function-based method or by the least-squares method. To ensure a smooth combination of f(x) and g(x), an appropriate weight function is employed. In numerical experiments, the proposed method is applied to large point data. The results illustrate that the proposed method can generate a smooth implicit function F(x) with natural behavior over the entire domain. In addition, on the given points, the accuracy of F(x) is exactly the same as that of f(x). Furthermore, the computational cost for generation of F(x) is almost the same as that of f(x). (author)

    Supply of materials to meet requirements and on time to open-cast and deep mines is essential to observe the defined production aims for the individual mines. The board of DSK commissioned the project ''Analysis of the entire DSK logistic chain'' with the aim of investigating all processes in material management logistics. In the follow-up project ''Optimisation of the entire DSK logistics chain'' restructuring measures will be worked out and their organisational integration in the entire company described. Starting with the present contribution first the results of the analysis project and subsequently the improvement measures along the DSK logistics chain are described. (orig.)

    Lipids are critical to cellular function and it is generally accepted that lipid turnover is rapid and dysregulation in turnover results in disease (Dawidowicz 1987; Phillips et al., 2009; Liu et al., 2013). In this study, we present an intriguing counter-example by demonstrating that in the center of the human ocular lens, there is no lipid turnover in fiber cells during the entire human lifespan. This discovery, combined with prior demonstration of pronounced changes in the lens lipid composition over a lifetime (Hughes et al., 2012), suggests that some lipid classes break down in the body over several decades, whereas others are stable. Such substantial changes in lens cell membranes may play a role in the genesis of age-related eye disorders. Whether long-lived lipids are present in other tissues is not yet known, but this may prove to be important in understanding the development of age-related diseases.

  19. Waste management aspects of entire PWR LOOP decontamination

    1988-01-01

    The waste management parameters for decontamination of an entire PWR primary circuit have been determined for dilute alkaline-permanganate/citric acid (APCA), LOMI, ozone and cerium acid process variations. APCA processes generate the largest waste volumes; over 140 m 3 (5000 ft 3 ) in some cases. This represents a potential disposal cost of one million dollars. The cation regeneration column makes the greatest contribution to the disposal volume. In contrast, the LOMI process generates approximately half as much waste, but it is expected to contain relatively high metal concentrations (200-800 ppm). The ozone and cerium acid processes product the least waste, usually under 45 m 3 . These waste volume estimates represent considerable fractions of a utility's annual disposal volume. Consequently, improved waste processing technology is required, and several approaches are suggested

    The Amazonian basin is the largest hydrological basin all over the world. In the recent past years, the basin has experienced an unusual succession of extreme draughts and floods, which origin is still a matter of debate. Yet, the amount of data available is poor, both over time and space scales, due to factor like basin's size, access difficulty and so on. One of the major locks is to get discharge series distributed over the entire basin. Satellite altimetry can be used to improve our knowledge of the hydrological stream flow conditions in the basin, through rating curves. Rating curves are mathematical relationships between stage and discharge at a given place. The common way to determine the parameters of the relationship is to compute the non-linear regression between the discharge and stage series. In this study, the discharge data was obtained by simulation through the entire basin using the MGB-IPH model with TRMM Merge input rainfall data and assimilation of gage data, run from 1998 to 2010. The stage dataset is made of ~800 altimetry series at ENVISAT and JASON-2 virtual stations. Altimetry series span between 2002 and 2010. In the present work we present the benefits of using stochastic methods instead of probabilistic ones to determine a dataset of rating curve parameters which are consistent throughout the entire Amazon basin. The rating curve parameters have been computed using a parameter optimization technique based on Markov Chain Monte Carlo sampler and Bayesian inference scheme. This technique provides an estimate of the best parameters for the rating curve, but also their posterior probability distribution, allowing the determination of a credibility interval for the rating curve. Also is included in the rating curve determination the error over discharges estimates from the MGB-IPH model. These MGB-IPH errors come from either errors in the discharge derived from the gage readings or errors in the satellite rainfall estimates. The present

    2005-01-01

    Alanine is an amino acid commonly used in ESR dosimetry as a reference detector. The classic approach for the measurement of irradiated samples is to determine the amplitude of the central peak of the first derivative spectrum. It is generally considered that this technique represents the best and most reproducible solution for achieving an accurate proportionality between the concentration of free radicals inside the resonant cavity, characterized by the amplitude, and the dose. It is also accepted that this central peak corresponds to the free radical CH 3 .CHCOO - . The hyperfine structure of this radical in the spectrum shows five main peaks with the approximate ratios 1:4:6:4:1 as regards coupling. This paper presents another approach featuring analysis of the entire spectrum: (i) ratios of identified peaks (ii) ratio variation vs time with regard to several parameters affecting fading. These variations in the alanine spectrum are probably correlated with the variation of the concentrations of different free radical species. These variations and their positions in the spectrum are very important constraints that increase the uncertainty of this type of measurement

    Floyd, M.; King, R. W.

    2017-12-01

    Through a collaborative effort of the GeoPRISMS East Africa Rift GPS Working Group, we have collected and collated all of the publicly available continuous and survey-mode data for the entire rift system between 1994 and 2017 and processed these data as part of a larger velocity solution for Africa, Arabia and western Eurasia. We present here our velocity solution encompassing the major bounding plates and intervening terranes along the East African Rift from the Red Sea to the Malawi Rift and adjacent regions for GPS sites with data spans of at least 2.4 years, and north and east velocity uncertainties less than 1.5 mm/yr. To obtain realistic uncertainties for the velocity estimates, we attempted at each stage of the analysis to account for the character of the noise: During phase processing, we used an elevation-dependent weighting based on the phase residuals for each station; we then examined each position time series, removing outliers and reweighting appropriately to account for the white noise component of the errors; and e accounted for temporal correlations by estimating an equivalent random-walk magnitude for each continuous site and applying the median value (0.5 mm/√yr) to all survey-mode sites. We rigorously estimate relative rotation rates of Nubia, by choosing subset of well-determined sites such that the effective weights of western, northeastern and southern Africa were roughly equivalent, and Somalia, for which the estimate is dominated by three sites (MALI, RCMN, SEY1) whose uncertainties are a factor of 2-3 smaller than those of the other sites. For both plates, the weighted root-mean-square of the velocity residuals is 0.5 mm/yr. Our unified velocity solution provides a geodetic framework and constraints on the continental-scale kinematics of surface motions as well as more local effects both within and outside of the rift structures. Specific focus areas with denser coverage than previous fields include the Danakil block, the Afar Rift, the

    An X-ray machine for production line inspection of tires places each tire in turn with one sector of the tire inside of a U-shaped arrangement of three fluorescent screens so that one screen faces the tread and the other two face the sides of the tire. An X-ray source inside the bead circle of the tire produces X-ray shadow pictures on the screens, which are separately viewed by a video camera, with an image of the picture on each screen transferred to a third of the target of a storage tube, so that a composite image of the entire width of the tire sector can be displayed on a picture tube. The tire is rotated step-wise for display of still pictures of every sector of the tire. (Auth.)

    Interdisciplinary research at the Ketzin pilot site in Germany contributes to the understanding of the geological CO2 storage since 2004. In addition to the research activities, public outreach has been a key element through the entire life-cycle of the project including site assessment, characterization, development as well as operation (2008-2013) and post-closure. From the very beginning of the project, the research activities were accompanied by an open dialogue with the general public including locals and interested people from all over Germany and the world. The visitor centre at the Ketzin site is run by GFZ and the most important contact point to inform about first-hand experiences from the project. Up to now, about 3,000 visitors came to the Ketzin site for guided tours and the annual open house days. In addition, project status and progress are disseminated in brochures and on the public website www.co2ketzin.de. The Ketzin project is also presented in short films, e.g. on monitoring, drilling and well closure. As the post-closure and pre-transfer phase started after the cease of CO2 injection in August 2013 and the injection facility was dismantled in December 2013, we were looking for a tool to further inform about the previous operation and site infrastructure. A virtual tour was set up for the Ketzin site which is accessible via the website. This tour includes several videos which virtually guide you on site and provide information on the (former) facilities. Public acceptance is a key issue for the Ketzin project as it is for any other CO2 storage project. For example, an open communication with the local residents helped to conduct large-scale seismic campaigns without severe restrictions. The experience from the Ketzin pilot site shows that honest communication and a diverse dissemination program is able to overcome critical public perception even for highly debated technologies.

    This article discusses how the program to map and sequence the human genome will be managed. The National Research Council (NRC) recommends that a 15-year $200-million-a-year effort to map all human genes should begin immediately. However, some people have balked at the idea, saying it is a ploy to raise money. Part of the skeptic's uneasiness stems from the involvement of the Department of Energy (DOE), an agency not often linked with biological research. The DOE's interest arises from its commitment to understanding the biological effects of nuclear radiation. Critics say it is a budget-boosting tactic. This article explains some of the arguments for and against the project and explains exactly what it would involve

    of the EDZ as well as hydro-chemical long-term stability in contact with different brines under diffusive and advective conditions, a comprehensive laboratory testing program is carried out. One of the most challenging aspects is the determination of the pre-experimental status of the core material that was provided for laboratory investigations, since the salt concrete was taken from an existing dam that has been loaded in-situ by the creeping rock salt for more than 10 years. Therefore, it is obvious that material properties, such as e.g. the initial gas permeability, have to be measured under a load comparable to the in-situ minimum stress. Within this paper preliminary results from laboratory investigations on salt concrete will be evaluated and an estimation of goals achievable within project lifetime will be given from a retrospective view on 24-month of investigation.

    1998-01-01

    To increase the use of biomass for energy production it is important to know the possible and significant environmental effects. A life cycle inventory (LCI) was made on a 1.3 MW el biomass CHP plant located in Reuthe/Vorarlberg/Austria with the purpose of analysing the different environmental burdens over the entire life cycle. The plant is fired with coarse and small fuelwood (10,000 t/yr) from industrial waste and forest residues. The boiler for the steam process has a moving grate burner and a muffle burner. The annual production is 4700 MWh of electricity and 29,000 MWh of district heat. The methodology of the analysis is orientated on the ISO Committee Draft of the Series 13,600. The analysis was carried out for the different sections of the biomass plant over their entire life cycle-construction (1 yr), operation (20 yrs) and dismantling (1 yr). The plant in Reuthe, which is the first cogeneration system of this kind in Austria, is a model for other similar projects. The results are shown as environmental burdens of one year and of the entire life cycle. Some results of the life cycle inventory, like the mass and energy balances, selected emissions to air, allocation results and effects on carbon storage pools are given. The results demonstrate that depending on the stage and the period of life, different environmental burdens become significant, i.e. CO 2 emissions of fossil fuels during construction. NO x emission during operation, emissions to soil during dismantling. The different options for allocation the environmental burdens to electricity and heat show a wide range of possible results, depending on the choice of allocation parameters (energy, exergy, credits for heat or electricity, price) i.e. for the particles emissions: 161 mg/kWh el to minus 566 mg/kWh el , 0 mg/kWh th to 118 mg/kWh th . With the results of the analysis it is thus possible for future similar projects to know when and where significant environmental burdens might be further

    2009-07-01

    There is a need for information about the response of Populus genotypes to repeated application of high-salinity water and nutrient sources throughout an entire rotation. We have combined establishment biomass and uptake data with mid- and full-rotation growth data to project potential chloride (Cl-) and sodium (Na+) uptake for 2- to 11-year-old Populus in the north central United States. Our objectives were to identify potential levels of uptake as the trees developed and stages of plantation development that are conducive to variable application rates of high-salinity irrigation. The projected cumulative uptake of Cl- and Na+ during mid-rotation plantation development was stable 2 to 3 years after planting but increased steadily from year 3 to 6. Year six cumulative uptake ranged from 22 to 175 kg Cl- ha(-1) and 8 to 74 kg Na+ ha(-1), while annual uptake ranged from 8 to 54 kg Cl- ha(-1) yr(-1) and 3 to 23 kg Na+ ha(-1) yr(-1). Full-rotation uptake was greatest from 4 to 9 years (Cl-) and 4 to 8 years (Na+), with maximum levels of Cl- (32 kg ha(-1) yr(-1)) and Na+ (13 kg ha(-1) yr(-1)) occurring in year six. The relative uptake potential of Cl- and Na+ at peak accumulation (year six) was 2.7 times greater than at the end of the rotation.

  12. Project financing

    1998-01-01

    Project financing was defined ('where a lender to a specific project has recourse only to the cash flow and assets of that project for repayment and security respectively') and its attributes were described. Project financing was said to be particularly well suited to power, pipeline, mining, telecommunications, petro-chemicals, road construction, and oil and gas projects, i.e. large infrastructure projects that are difficult to fund on-balance sheet, where the risk profile of a project does not fit the corporation's risk appetite, or where higher leverage is required. Sources of project financing were identified. The need to analyze and mitigate risks, and being aware that lenders always take a conservative view and gravitate towards the lowest common denominator, were considered the key to success in obtaining project financing funds. TransAlta Corporation's project financing experiences were used to illustrate the potential of this source of financing

    Hoppe, W.

    1978-01-01

    For the licensing of power plants, nuclear power plants and other industrial large projects, the question of the building law admissibility gains more and more importance in the licensing procedure. According to paragraph 6 of the Fed. Immission Protection, it is not only necessary that immission protection duties of the operator of plants which are subject to licensing are fulfilled, but other public law regulations must be in correspondance with the construction and operation of the plant. In this connection, the planning law admissibility of the project must also be examined. This is also valid for nuclear power plants. In the practical application of licensing such plants are treated in different ways, as far as terms of building planning are concerned. Some licensing authorities regard them as priviledged outskirts projects, others demand a zoning plan of the community. The author pleads for such large projects to be licensed only on the basis of a zoning plan set up by the community. (orig.) [de

    We address cancer communication by creating and assessing the impacts of a theatrical production, When Cancer Calls…(WCC…), anchored in conversations from the first natural history of a patient and family members talking through cancer on the telephone. A national study was conducted using a multi-site and randomized controlled trial. An 80-minute video was produced to assess viewing impacts across cancer patients, survivors, and family members. Comparisons were made with a control video on cancer nutrition and diet. Pretest-posttest sample size was 1006, and 669 participants completed a 30-day follow-up impacts assessment. All five family and communication indices increased significantly for WCC…. When compared to the placebo, average pretest-posttest change scores were higher for self-efficacy (775%), family fabric (665%), outside support (189%), and family communication (97%). One month following viewings, WCC…participants reported 30% more conversations about cancer among patients and family members about cancer. A new genre of Entertainment-Education (E-E) was created that triggers positive reactions from audience members. Managing delicate and often complex communication about the trials, tribulations, hopes, and triumphs of cancer journeys is fundamentally important for everyday living. Unique opportunities exist to make WCC… available to national and global audiences, create tailored curricula, and integrate these viewings into educational programs for patients, family members, and care-provider teams across diverse health, corporate, and governmental systems.

  17. The developmental programme for genesis of the entire kidney is recapitulated in Wilms tumour

    Anaka, Matthew R.; Morison, Ian M.; Reeve, Anthony E.

    2017-01-01

    Wilms tumour (WT) is an embryonal tumour that recapitulates kidney development. The normal kidney is formed from two distinct embryological origins: the metanephric mesenchyme (MM) and the ureteric bud (UB). It is generally accepted that WT arises from precursor cells in the MM; however whether UB-equivalent structures participate in tumorigenesis is uncertain. To address the question of the involvement of UB, we assessed 55 Wilms tumours for the molecular features of MM and UB using gene expression profiling, immunohistochemsitry and immunofluorescence. Expression profiling primarily based on the Genitourinary Molecular Anatomy Project data identified molecular signatures of the UB and collecting duct as well as those of the proximal and distal tubules in the triphasic histology group. We performed immunolabeling for fetal kidneys and WTs. We focused on a central epithelial blastema pattern which is the characteristic of triphasic histology characterized by UB-like epithelial structures surrounded by MM and MM-derived epithelial structures, evoking the induction/aggregation phase of the developing kidney. The UB-like epithelial structures and surrounding MM and epithelial structures resembling early glomerular epithelium, proximal and distal tubules showed similar expression patterns to those of the developing kidney. These observations indicate WTs can arise from a precursor cell capable of generating the entire kidney, such as the cells of the intermediate mesoderm from which both the MM and UB are derived. Moreover, this provides an explanation for the variable histological features of mesenchymal to epithelial differentiation seen in WT. PMID:29040332

    Space Systems Architecture has been expanded into a process by the US Department of Defense for their large scale systems of systems development programs. This paper uses the steps in the process to establishes a framework for Space Elevator systems to be developed and provides a methodology to manage complexity. This new approach to developing a family of systems is based upon three architectural views: Operational View OV), Systems View (SV), and Technical Standards View (TV). The top level view of the process establishes the stages for the development of the first Space Elevator and is called Architectural View - 1, Overview and Summary. This paper will show the guidelines and steps of the process while focusing upon components of the Space Elevator Preliminary Architecture View. This Preliminary Architecture View is presented as a draft starting point for the Space Elevator Project.

This was a project that pretended the consolidation of a modern state through the elements of power as the religion, the education and the language, which allowed organizing a new political – administrative system of a centralistic status, in other words, that through the constitution of 1886 a social order be imposed, establishing a strong State, moved by a central government. Through these elements, it will be explained how the change from a Sovereign State of Boyacá to a Political and Administrative Department happened, which lead to a series of reforms of an economical, political and social status, that next to the transition of a secular education to a confessional education, determined the destiny of the Department from a Political Project of the Regeneration.

    Full Text Available In this paper, we obtain new sufficient conditions of boundedness of L-index in joint variables for entire function in Cn functions. They give an estimate of maximum modulus of an entire function by its minimum modulus on a skeleton in a polydisc and describe the behavior of all partial logarithmic derivatives and the distribution of zeros. In some sense, the obtained results are new for entire functions of bounded index and l-index in C too. They generalize known results of Fricke, Sheremeta, and Kuzyk.

  7. Entire solutions of a diffusive and competitive Lotka–Volterra type system with nonlocal delays

    Wang, Mingxin; Lv, Guangying

    2010-01-01

    This paper is concerned with the entire solution of a diffusive and competitive Lotka–Volterra type system with nonlocal delays. The existence of the entire solution is proved by transforming the system with nonlocal delays to a four-dimensional system without delay and using the comparing argument and the sub-super-solution method. Here an entire solution means a classical solution defined for all space and time variables, which behaves as two wave fronts coming from both sides of the x-axis

    Pinelli, Thomas E.; Kennedy, John M.

    1991-01-01

    The project examines how the results of NASA/DOD research diffuse into the aerospace R&D process, and empirically analyzes the implications of the aerospace knowledge diffusion process. Specific issues considered are the roles played by government technical reports, the recognition of the value of scientific and technical information (STI), and the optimization of the STI aerospace transfer system. Information-seeking habits are assessed for the U.S. aerospace community, the general community, the academic sector, and the international community. U.S. aerospace engineers and scientists use 65 percent of working time to communicate STI, and prefer 'internal' STI over 'external' STI. The isolation from 'external' information is found to be detrimental to U.S. aerospace R&D in general.

    Science.gov (United States)

    Khan, M E; Mishra, Anurag; Morankar, Sudhakar

    Increase in extramarital sex among youths, gender-based violence, lack of contraceptive knowledge among newly married couples and lack of knowledge of protection against diseases like STIs/HIV are the information and service needs of young people that need to be addressed urgently in order to make them future knowledgeable, responsible, and non-violent partners. In addressing these needs the gatekeepers, including parents, formal and informal community leaders and teachers, play a critical role, by facilitating/hindering access to appropriate and correct information about sexual and reproductive health to young people. The study was conducted in a district of Uttaranchal, India. The specific objective was to understand the social context and gatekeepers' views on family planning and sexual and reproductive health needs of young men. Thirty-two in-depth interviews and four focus group discussions were conducted with parents, formal and informal community leaders, teachers, and selected development officials. The findings indicate that gatekeepers are worried about rapid changes in the aspiration, expectation, and behavior of young men. Most of them were seriously concerned about the increasing drinking habit, use of drugs, and changing values of sexuality leading to various risk behaviors among young men. They felt that many of these changes are consequences of wider societal changes, rising aspirations, explosion of electronic media, and globalization of a new youth culture where extramarital sex, alcohol consumption, and violence are expressions of different facets of masculinity and symbols of the affluent class. Overall, there was a feeling that TV/films and their peers now influence more the socialization of young people and parents are losing control in guidance and mentoring of their children.

    Full Text Available The objective of the research was to determine the chemical composition as well as the physicochemical properties of the longissimus muscle from Korean entire and castrate elk. Twelve elk stags were raised and fed on concentrate with ad libitum hay. All animals were equally divided into castrated and non-castrated (entire males, and slaughtered at 5 year of age. It was found that entire elk, in comparison with castrate elk, had higher content of moisture and lower content of fat (p<0.05. Compared with entire males, the castrates had lower pH and shear force values (p<0.05. However, castrates had higher L*, a*, and b* values compared with entires (p<0.05. An analysis of the fatty acid profile revealed that the muscles of entire and castrate elk had the most abundant concentrations of the following fatty acids: palmitic acid (C16:0 of the saturated fatty acid, and oleic acid (C18:1n-9 of the unsaturated fatty acid. The entire elk contains higher proportions of linoleic acid (C18:3n6, eicosenoic acid (C20:1n9, and arachidonic acid (C20:4n6 (p<0.05. Cholesterol content in elk was not affected by castration. The predominant free amino acid was glutamic acid related to umami taste. It is apparent that the castrate animals carried higher content of histidine, isoleucine, and leucine than those of the entire group (p<0.05. In this study, it was concluded that venison quality of elk is affected by castration and these results can provide fundamental information for venison production.

    The "zograscope" is a "visual aid" (commonly known as "optical machine" in the 18th century) invented in the mid-18th century, and in general use until the early 20th century. It was intended to view single pictures (thus not stereographic pairs) with both eyes. The optics approximately eliminates the physiological cues (binocular disparity, vergence, accommodation, movement parallax, and image blur) that might indicate the flatness of the picture surface. The spatial structure of pictorial space is due to the remaining pictorial cues. As a consequence, many (or perhaps most) observers are aware of a heightened "plasticity" of the pictorial content for zograscopic as compared with natural viewing. We discuss the optics of the zograscope in some detail. Such an analysis is not available in the literature, whereas common "explanations" of the apparatus are evidently nonsensical. We constructed a zograscope, using modern parts, and present psychophysical data on its performance.

    1988-04-15

    Remote viewing is the supposed faculty which enables a percipient, sited in a closed room, to describe the perceptions of a remote agent visiting an unknown target site. To provide convincing demonstration of such a faculty poses a range of experimental and practical problems, especially if feedback to the percipient is allowed after each trial. The precautions needed are elaborate and troublesome; many potential loopholes have to be plugged and there will be strong temptations to relax standards, requiring exceptional discipline and dedication by the experimenters. Most reports of remote viewing experiments are rather superficial and do not permit assessment of the experimental procedures with confidence; in many cases there is clear evidence of particular loopholes left unclosed. Any serious appraisal of the evidence would have to go beyond the reports. Meanwhile the published evidence is far from compelling, and certainly insufficient to justify overthrow of well-established scientific principles.

    Scandurra, Isabella; Hägglund, Maria

    2009-01-01

    Introduction Integrated care involves different professionals, belonging to different care provider organizations and requires immediate and ubiquitous access to patient-oriented information, supporting an integrated view on the care process [1]. Purpose To present a method for development of usable and work process-oriented information and communication technology (ICT) systems for integrated care. Theory and method Based on Human-computer Interaction Science and in particular Participatory Design [2], we present a new collaborative design method in the context of health information systems (HIS) development [3]. This method implies a thorough analysis of the entire interdisciplinary cooperative work and a transformation of the results into technical specifications, via user validated scenarios, prototypes and use cases, ultimately leading to the development of appropriate ICT for the variety of occurring work situations for different user groups, or professions, in integrated care. Results and conclusions Application of the method in homecare of the elderly resulted in an HIS that was well adapted to the intended user groups. Conducted in multi-disciplinary seminars, the method captured and validated user needs and system requirements for different professionals, work situations, and environments not only for current work; it also aimed to improve collaboration in future (ICT supported) work processes. A holistic view of the entire care process was obtained and supported through different views of the HIS for different user groups, resulting in improved work in the entire care process as well as for each collaborating profession [4].

  18. Water rights of the head reach farmers in view of a water supply scenario at the extension area of the Babai Irrigation Project, Nepal

    Science.gov (United States)

    Adhikari, B.; Verhoeven, R.; Troch, P.

    The farmer managed irrigation systems (FMIS) represent those systems which are constructed and operated solely by the farmers applying their indigenous technology. The FMIS generally outperform the modern irrigation systems constructed and operated by the government agencies with regard to the water delivery effectiveness, agricultural productivity etc., and the presence of a sound organization responsible to run the FMIS, often referred to as the ‘social capital’, is the key to this success. This paper studies another important aspect residing in the FMIS: potentials to expand the irrigation area by means of their proper rehabilitation and modernization. Taking the case study of the Babai Irrigation Project in Nepal, it is demonstrated that the flow, which in the past was used to irrigate the 5400 ha area covered by three FMIS, can provide irrigation to an additional 8100 ha in the summer, 4180 ha vegetables in the winter and 1100 ha maize in the spring season after the FMIS rehabilitation. The “priority water rights” of the FMIS part have been evaluated based on relevant crop water requirement calculations and is found to be equal to 85.4 million m 3 per year. Consequently, the dry season irrigation strategy at the extension area could be worked out based on the remaining flow. By storing the surplus discharge of the monsoon and autumn in local ponds, and by consuming them in dry period combined with nominal partial irrigation practice, wheat and mustard can be cultivated over about 4000 ha of the extension area. Furthermore, storage and surface irrigation both contribute to the groundwater recharge. The conjunctive use of ground, surface and harvested water might be the mainstream in the future for a sustainable irrigation water management in the region.

    The evaluation of treatment integrity (therapist adherence and competence) is a necessary condition to ensure the internal and external validity of psychotherapy research. However, the evaluation process is associated with high costs, because therapy sessions must be rated by experienced clinicians. It is debatable whether rating session segments is an adequate alternative to rating entire sessions. Four judges evaluated treatment integrity (i.e., therapist adherence and competence) in 84 randomly selected videotapes of cognitive-behavioral therapy for major depressive disorder, social anxiety disorder, and hypochondriasis (from three different treatment outcome studies). In each case, two judges provided ratings based on entire therapy sessions and two on session segments only (i.e., the middle third of the entire sessions). Interrater reliability of adherence and competence evaluations proved satisfactory for ratings based on segments and the level of reliability did not differ from ratings based on entire sessions. Ratings of treatment integrity that were based on entire sessions and session segments were strongly correlated (r=.62 for adherence and r=.73 for competence). The relationship between treatment integrity and outcome was comparable for ratings based on session segments and those based on entire sessions. However, significant relationships between therapist competence and therapy outcome were only found in the treatment of social anxiety disorder. Ratings based on segments proved to be adequate for the evaluation of treatment integrity. The findings demonstrate that session segments are an adequate and cost-effective alternative to entire sessions for the evaluation of therapist adherence and competence. Copyright © 2014.

    Despite obvious improvements in visualization of the in vivo cornea through the faster imaging speeds and higher axial resolutions, cellular imaging stays unresolvable task for OCT, as en face viewing with a high lateral resolution is required. The latter is possible with FFOCT, a method that relies on a camera, moderate numerical aperture (NA) objectives and an incoherent light source to provide en face images with a micrometer-level resolution. Recently, we for the first time demonstrated the ability of FFOCT to capture images from the in vivo human cornea1. In the current paper we present an extensive study of appearance of healthy in vivo human corneas under FFOCT examination. En face corneal images with a micrometer-level resolution were obtained from the three healthy subjects. For each subject it was possible to acquire images through the entire corneal depth and visualize the epithelium structures, Bowman's layer, sub-basal nerve plexus (SNP) fibers, anterior, middle and posterior stroma, endothelial cells with nuclei. Dimensions and densities of the structures visible with FFOCT, are in agreement with those seen by other cornea imaging methods. Cellular-level details in the images obtained together with the relatively large field-of-view (FOV) and contactless way of imaging make this device a promising candidate for becoming a new tool in ophthalmological diagnostics.

    A novel High-Throughput Continuous Hydrothermal (HiTCH) flow synthesis reactor was used to make directly and rapidly a 66-sample nanoparticle library (entire phase diagram) of nanocrystalline Ce(x)Zr(y)Y(z)O(2-delta) in less than 12 h. High resolution PXRD data were obtained for the entire heat-treated library (at 1000 degrees C/1 h) in less than a day using the new robotic beamline I11, located at Diamond Light Source (DLS). This allowed Rietveld-quality powder X-ray diffraction (PXRD) data collection of the entire 66-sample library in <1 day. Consequently, the authors rapidly mapped out phase behavior and sintering behaviors for the entire library. Out of the entire 66-sample heat-treated library, the PXRD data suggests that 43 possess the fluorite structure, of which 30 (out of 36) are ternary compositions. The speed, quantity and quality of data obtained by our new approach, offers an exciting new development which will allow structure-property relationships to be accessed for nanoceramics in much shorter time periods.

  6. Normal tendon sheath of the second to fifth fingers as seen on oblique views

    1984-01-01

    Oblique views of the fingers, using a low kilovolt technique, show a portion of the tendon sheaths which can be regarded as representative of the entire sheath. Because of the varying obliquity of each finger, this proportion differs in the fingers. With increasing age the projected portion of the sheath becomes smaller because it is covered by increasing bone formation in the insertion of the tendon sheat. Normal values have been obtained for adults according to their decades; from these, quite minor degrees of tendon sheat thickening can be determined. In camptodactyly of the fifth finger, which is not uncommon, the tendon sheat may be widened in the absence of a tenosynovitis.

    Purpose: To improve the safety of reactor operation by enabling to detect the states and positions of fuel assemblies over a wide range with a set of ultrasonic viewing device comprising a rotatable ultrasonic transmitter-receiver and a reflector mounted with an adjustable angle. Constitution: A driving portion for a ultrasonic viewing device is provided to a rotary plug closing the opening of a reactor vessel and a guide pipe suspending below the coolant level is provided to the driving portion. An ultrasonic transmitter-receiver is provided at the end of the holder tube in the guide pipe. A reflector is provided at the upper position of the reactor core so as to correspond to the ultrasonic transmitter-receiver. The ultrasonic transmitter-receiver, positioned by the driving portion, performs horizontal movement for scanning the entire surface of the top of the reactor core, as well as vertical movement covering the gap between the upper mechanism on the reactor and the reactor core, whereby the confirmation for the separation of the control rod and the detection for the states of the reactor core can be conducted by the reflection waves from the reflector.

    Full Text Available An audiovisual interface equipped with a projector, an inclina-tion sensor, and a distance sensor for zoom control has been developed that enables a user to selectively view and listen to specific performers in a video-taped group performance. Dubbed Concert Viewing Headphones, it has both image and sound processing functions. The image processing extracts the portion of the image indicated by the user and projects it free of distortion on the front and side walls. The sound processing creates imaginary microphones for those performers without one so that the user can hear the sound from any performer. Testing using images and sounds captured using a fisheye-lens camera and 37 lavalier microphones showed that sound locali-zation was fastest when an inverse square function was used for the sound mixing and that the zoom function was useful for locating the desired sound performance.

    To create and evaluate normalized T1rho profiles of the entire femoral cartilage in healthy subjects with three-dimensional (3D) angle- and depth-dependent analysis. T1rho images of the knee from 20 healthy volunteers were acquired on a 3.0-T unit. Cartilage segmentation of the entire femur was performed slice-by-slice by a board-certified radiologist. The T1rho depth/angle-dependent profile was investigated by partitioning cartilage into superficial and deep layers, and angular segmentation in increments of 4 over the length of segmented cartilage. Average T1rho values were calculated with normalized T1rho profiles. Surface maps and 3D graphs were created. T1rho profiles have regional and depth variations, with no significant magic angle effect. Average T1rho values in the superficial layer of the femoral cartilage were higher than those in the deep layer in most locations (p < 0.05). T1rho values in the deep layer of the weight-bearing portions of the medial and lateral condyles were lower than those of the corresponding non-weight-bearing portions (p < 0.05). Surface maps and 3D graphs demonstrated that cartilage T1rho values were not homogeneous over the entire femur. Normalized T1rho profiles from the entire femoral cartilage will be useful for diagnosing local or early T1rho abnormalities and osteoarthritis in clinical applications. (orig.)

    To investigate the dependence of microcalcification cluster detectability on tomographic scan angle, angular increment, and number of projection views acquired at digital breast tomosynthesis ( DBT digital breast tomosynthesis ). A prototype DBT digital breast tomosynthesis system operated in step-and-shoot mode was used to image breast phantoms. Four 5-cm-thick phantoms embedded with 81 simulated microcalcification clusters of three speck sizes (subtle, medium, and obvious) were imaged by using a rhodium target and rhodium filter with 29 kV, 50 mAs, and seven acquisition protocols. Fixed angular increments were used in four protocols (denoted as scan angle, angular increment, and number of projection views, respectively: 16°, 1°, and 17; 24°, 3°, and nine; 30°, 3°, and 11; and 60°, 3°, and 21), and variable increments were used in three (40°, variable, and 13; 40°, variable, and 15; and 60°, variable, and 21). The reconstructed DBT digital breast tomosynthesis images were interpreted by six radiologists who located the microcalcification clusters and rated their conspicuity. The mean sensitivity for detection of subtle clusters ranged from 80% (22.5 of 28) to 96% (26.8 of 28) for the seven DBT digital breast tomosynthesis protocols; the highest sensitivity was achieved with the 16°, 1°, and 17 protocol (96%), but the difference was significant only for the 60°, 3°, and 21 protocol (80%, P .99). The conspicuity of subtle and medium clusters with the 16°, 1°, and 17 protocol was rated higher than those with other protocols; the differences were significant for subtle clusters with the 24°, 3°, and nine protocol and for medium clusters with 24°, 3°, and nine; 30°, 3°, and 11; 60°, 3° and 21; and 60°, variable, and 21 protocols (P tomosynthesis provided higher sensitivity and conspicuity than wide-angle DBT digital breast tomosynthesis for subtle microcalcification clusters. © RSNA, 2014.

    Synthesis and evaluation of an entirely S-protected chitosan as mucoadhesive excipient for vaginal drug delivery. N-acetyl-cysteine was linked to 6-mercaptonicotinamide via disulphide exchange reaction. The obtained ligand, NAC-6-MNA, was subsequently attached to chitosan by carbodiimide mediated amide bond formation in two concentrations. The synthesized S-protected chitosan was chemically characterized and mucoadhesive properties and stability against oxidation were investigated. Moreover, metronidazole tablets comprising the S-protected chitosan were evaluated regarding water uptake capacity, disintegration behaviour, residence time on vaginal mucosa, release of the encapsulated drug and antimicrobial activity. S-protected chitosan displayed 160±19 (CS-MNA-160) and 320±38 (CS-MNA-320)µmol of ligand per gram of polymer. At pH 4.2, CS-MNA-160 and CS-MNA-320 showed 5.2-fold and 6.2-fold increase in mucus viscosity in comparison to unmodified chitosan (One-way ANOVA, pchitosan remained stable against oxidation in presence of 0.5%v/v hydrogen peroxide. Metronidazole tablets consisting in S-protected chitosan showed prolonged residence time on vaginal mucosa and improved water uptake capacity and disintegration time in comparison to tablets consisting of unmodified chitosan. Moreover, CS-MNA-320 metronidazole tablets displayed prolonged drug release and antimicrobial activity. On the basis of the achieved results, entirely S-protected chitosan represents a promising excipient for the development of metronidazole vaginal tablets. S-protected thiomers are polymers modified with thiol groups protected by aromatic ligands and characterized by strong mucoadhesive properties and high stability against oxidation. Up to date, the entirely S-protection of thiol groups was achieved via the synthesis of the ligand 2-((2-amino-2-carboxyethyl)disulfanyl)nicotinic acid) which can be directly bound to the backbone of polymers bearing carboxylic moieties as pectin.

    Taking a long view with respect to power generating assets involves establishing an asset's current competitiveness, determining where it needs to be to remain competitive in the future, and then making the necessary operating and maintenance modifications to get there. The Panther Creek Energy Facility - a Bechtel-designed 83 MW Pyroflow circulating fluidized bed boiler plant in Nesquehoning, PA, managed by Panther Creek Partners (a joint venture between Constellation Power and Ahlstrom Development) and maintained and operated by Constellation Operating Services - provides an excellent example. Here after, a 35-day outage, the outage interval was investigated. OEMs and service provides are increasingly shifting to work with the powerplant instead of for it. TVA for example initially focused on major maintenance and capital ipmrovement projects but subsequently extended to smaller O & M activities. A strategy for space parts needs careful consideration, particularly for nuclear power plants. Several nuclear utilities are investigating inventory management solutions from Wesco. Component obsolescence is another important issue again especially for nuclear utilities. Solutions being found in the nuclear industry will benefit the entire power generation industry. 3 refs., 2 figs., 1 tab., 3 photos.

    Full Text Available Acute agrochemical poisoning is a leading cause of mortality and morbidity in India. Pendimethalin (herbicide and Pancycuron (fungicide are frequently used worldwide and considered quite a remarkably safe one for humans. Their acute toxicity is not yet widely known. Here we are reporting cases of their acute poisoning in young. To the best of our knowledge not a single such case of their poisoning has been reported so far in india. Such poisoning by entirely new compounds is an emerging problem in the tropics. In this communication we are reporting such unusual and entirely new toxicities and trying to highlight the need of their early recognition and timely management in rural regions where health facilities are already at the stake.

  7. Infarction of the entire corpus callosum as a complication in subarachnoid hemorrhage: A case report

    Directory of Open Access Journals (Sweden)

    Satoru Takahashi, M.D.

    2017-03-01

    Full Text Available The corpus callosum is the major commissural pathway connecting the cerebral hemispheres. This pathway receives its blood supply from anterior communicating artery, pericallosal artery, and posterior pericallosal artery. However, in some cases, the entire corpus callosum is supplied by median callosal artery; thus, occlusion of this artery can lead to infarction of the entire corpus callosum. Few reports have described this type of infarction, and no reports after subarachnoid hemorrhage (SAH exist. Here, we report on a 42-year-old female who was diagnosed with SAH after two aneurysms were discovered in bifurcation of left anterior cerebral artery (A1-A2. After successful clipping was performed, the patient was alert and had no neurological deficits; moreover, the computed tomography images that were acquired after the operation showed no evidence of infarction. Nine days after admittance to the hospital, drowsiness and weakness of the left limbs with brain swelling appeared and decompressive hemi-craniectomy was performed. Diagnostic cerebral angiography revealed vasospasms in both anterior and middle cerebral arteries, thus fasudil hydrochloride was administered intra-arterially. While blood flow in all arteries improved, diffusion-weighted magnetic resonance imaging detected infarction along the entire length of the corpus callosum and in the medial region of the right frontal lobe. We believe this infarction was due to secondary ischemia of median callosal artery. This case reminded us of the anatomical variation wherein median callosal artery is the sole blood supply line for the corpus callosum and demonstrated that infarction of the entire corpus callosum is possible.

    The Douady-Hubbard landing theorem for periodic external rays is one of the cornerstones of the study of polynomial dynamics. It states that, for a complex polynomial with bounded postcritical set, every periodic external ray lands at a repelling or parabolic periodic point, and conversely every repelling or parabolic point is the landing point of at least one periodic external ray. We prove an analogue of this theorem for an entire function with bounded postsingular set: every periodic dread...

  11. Massive and Reproducible Production of Liver Buds Entirely from Human Pluripotent Stem Cells

    2017-12-01

    Full Text Available Summary: Organoid technology provides a revolutionary paradigm toward therapy but has yet to be applied in humans, mainly because of reproducibility and scalability challenges. Here, we overcome these limitations by evolving a scalable organ bud production platform entirely from human induced pluripotent stem cells (iPSC. By conducting massive “reverse” screen experiments, we identified three progenitor populations that can effectively generate liver buds in a highly reproducible manner: hepatic endoderm, endothelium, and septum mesenchyme. Furthermore, we achieved human scalability by developing an omni-well-array culture platform for mass producing homogeneous and miniaturized liver buds on a clinically relevant large scale (>108. Vascularized and functional liver tissues generated entirely from iPSCs significantly improved subsequent hepatic functionalization potentiated by stage-matched developmental progenitor interactions, enabling functional rescue against acute liver failure via transplantation. Overall, our study provides a stringent manufacturing platform for multicellular organoid supply, thus facilitating clinical and pharmaceutical applications especially for the treatment of liver diseases through multi-industrial collaborations. : With the goal of clinical translation of liver bud transplant therapy, Takebe et al. established a massive organoid production platform from endoderm, endothelial, and mesenchymal progenitor populations specified entirely from human iPSCs, reproducibly demonstrating functionality both in vitro and in vivo.

    The Watchdog Project completed 100% of the project Statement of Project Objective (SOPO). The Watchdog project was a very aggressive project looking to accomplish commercialization of technology that had never been commercialized, as a result it took six years to complete not the original three that were planned. No additional federal funds were requested from the original proposal and SEL contributed the additional cost share required to complete the project. The result of the Watchdog Project is the world’s first industrial rated Software Defined Network (SDN) switch commercially available. This technology achieved the SOPOO and DOE Roadmap goals to have strong network access control, improve reliability and network performance, and give the asset owner the ability to minimize attack surface before and during an attack. The Watchdog project is an alliance between CenterPoint Energy Houston Electric, Pacific Northwest National Laboratories (PNNL), and Schweitzer Engineering Laboratories, Inc. (SEL). SEL is the world’s leader in microprocessor-based electronic equipment for protecting electric power systems. PNNL performs basic and applied research to deliver energy, environmental, and national security for our nation. CenterPoint Energy is the third largest publicly traded natural gas delivery company in the U.S and third largest combined electricity and natural gas delivery company. The Watchdog Project efforts were combined with the SDN Project efforts to produce the entire SDN system solution for the critical infrastructure. The Watchdog project addresses Topic Area of Interest 5: Secure Communications, for the DEFOA- 0000359 by protecting the control system local area network itself and the communications coming from and going to the electronic devices on the local network. Local area networks usually are not routed and have little or no filtering capabilities. Combine this with the fact control system protocols are designed with inherent trust the control

    UPGMA (average linking) is probably the most popular algorithm for hierarchical data clustering, especially in computational biology. However, UPGMA requires the entire dissimilarity matrix in memory. Due to this prohibitive requirement, UPGMA is not scalable to very large datasets. We present a novel class of memory-constrained UPGMA (MC-UPGMA) algorithms. Given any practical memory size constraint, this framework guarantees the correct clustering solution without explicitly requiring all dissimilarities in memory. The algorithms are general and are applicable to any dataset. We present a data-dependent characterization of hardness and clustering efficiency. The presented concepts are applicable to any agglomerative clustering formulation. We apply our algorithm to the entire collection of protein sequences, to automatically build a comprehensive evolutionary-driven hierarchy of proteins from sequence alone. The newly created tree captures protein families better than state-of-the-art large-scale methods such as CluSTr, ProtoNet4 or single-linkage clustering. We demonstrate that leveraging the entire mass embodied in all sequence similarities allows to significantly improve on current protein family clusterings which are unable to directly tackle the sheer mass of this data. Furthermore, we argue that non-metric constraints are an inherent complexity of the sequence space and should not be overlooked. The robustness of UPGMA allows significant improvement, especially for multidomain proteins, and for large or divergent families. A comprehensive tree built from all UniProt sequence similarities, together with navigation and classification tools will be made available as part of the ProtoNet service. A C++ implementation of the algorithm is available on request.

    “La mirada vigente” is a homenage to Dan Beninson, who was one of the creators of radiation protection worldwide. He taught several generations of nuclear scientists in our country and abroad, playing a key role in the scientific-technological development of Argentina. He was also one of the key figures in the nuclear activity of our country; the creator of the institution that ensures its safety. Likewise, this book, is a testament about what this man meant for many people in Argentina (his country) and in the world (his yard); and simultaneously, a testament of the key moments in the history of a scientific discipline and the activity to which he dedicated his entire life. “La mirada vigente” is also a testimony of other individuals’ point of view. The eyes of others over the features of his person, and career, and his achievements. But above all, it provides a personal and almost intimate perspective, about specific episodes that describe his interesting life. “La mirada vigente” is the exploration of his versatile life, rich as only a few. And the reflection of a work legacy that still remain alive. [es

    Embryonic lethality in mice with targeted gene deletion is a major issue that can be circumvented by using Cre-loxP-based animal models. Various inducible Cre systems are available, e.g. such that are activated following tamoxifen treatment, and allow deletion of a specific target gene at any desired time point during the life span of the animal. In this study, we describe the efficiency of topical tamoxifen administration by eye drops using a Cre- reporter mouse strain (R26R). We report that tamoxifen-responsive CAGGCre-ER (TM) mice show a robust Cre- mediated recombination throughout the entire eye.

    Full Text Available Giant cell tumor of the bones occurring in the first metacarpals frequently requires entire metacarpal resection due to the aggressive nature and high rate of recurrence. Bone reconstruction can be performed with autogenous bone grafts. Here we describe a new technique of reconstruction using a patient-matched three-dimensional printed titanium first metacarpal prosthesis. This prosthesis has a special design for ligament reconstruction in the proximal and distal portions. Good hand function and aesthetic appearance were maintained at a 24-month follow-up visit. This reconstructive technique can avoid donor-site complications and spare the autogenous bone grafts for revision options.

    We consider certain spaces P Ω of entire functions of exponential type in C n associated with a domain Ω element of R n that are in fact Laplace transforms of distributions in Ω. It is shown that any shift-invariant subspace of these functions admits spectral synthesis, that is, coincides with the closure of the linear span of the exponential polynomials contained in it. As an application of this result, we describe the solution space in P Ω of a system of homogeneous equations of infinite order for differential operators with characteristic functions infinitely differentiable in Ω

    This article presents an innovative approach to include occupational exposures to organic chemicals in life cycle impact assessment (LCIA) by building on the characterization factors set out in Kijko et al. (2015) to calculate the potential impact of occupational exposure over the entire supply chain of product or service. Based on an economic input-output model and labor and economic data, the total impacts per dollar of production are provided for 430 commodity categories and range from 0.025 to 6.6 disability-adjusted life years (DALY) per million dollar of final economic demand. The approach is applied on a case study assessing human health impacts over the life cycle of a piece of office furniture. It illustrates how to combine monitoring data collected at the manufacturing facility and averaged sector specific data to model the entire supply chain. This paper makes the inclusion of occupational exposure to chemicals fully compatible with the LCA framework by including the supply chain of a given production process and will help industries focus on the leading causes of human health impacts and prevent impact shifting.

  12. Entire mesodermal mantle behaves as Spemann's organizer in dorsoanterior enhanced Xenopus laevis embryos

    The body plan of Xenopus laevis can be respecified by briefly exposing early cleavage stage embryos to lithium. Such embryos develop exaggerated dorsoanterior structures such as a radial eye and cement gland. In this paper, we demonstrate that the enhanced dorsoanterior phenotype results from an overcommitment of mesoderm to dorsoanterior mesoderm. Histological and immunohistochemical observations reveal that the embryos have a greatly enlarged notochord with very little muscle tissue. In addition, they develop a radial, beating heart, suggesting that lithium also specifies anterior mesoderm and pharyngeal endoderm. Randomly oriented diametrically opposed marginal zone grafts from lithium-treated embryos, when transplanted into ultraviolet (uv)-irradiated axis-deficient hosts, rescue dorsal axial structures. These transplantation experiments demonstrate that the entire marginal zone of the early gastrula consists of presumptive dorsal mesoderm. Vital dye marking experiments also indicate that the entire marginal zone maps to the prominent proboscis that is composed of chordamesoderm and represents the long axis of the embryo. These results suggest that lithium respecifies the mesoderm of Xenopus laevis embryos so that it differentiates into the Spemann organizer. We suggest that the origin of the dorsoanterior enhanced phenotypes generated by lithium and the dorsoanterior deficient phenotypes generated by uv irradiation are due to relative quantities of organizer. Our evidence demonstrates the existence of a continuum of body plan phenotypes based on this premise

    Recent experimental and numerical investigations of the nucleate boiling heat transfer process at a single active nucleation site are presented and used for an evaluation of the local heat fluxes during the entire life time of a vapor bubble from its nucleation to the rise through the thermal boundary layer. In a special boiling cell, vapor bubbles are generated at a single nucleation site on a 20 {mu}m thin stainless steel heating foil. An infrared camera captures the temperature distribution at the wall with high temporal and spatial resolution. The bubble shape is recorded with a high-speed camera. Measurements were conducted with the pure fluids FC-84 and FC-3284 and with its binary mixtures. For pure fluids, up to 50-60% of the latent heat flows through the three-phase-contact line region. For mixtures, this ratio is clearly reduced. These observations are in agreement with the numerical model of the author's group. The fully transient model contains a multi scale approach ranging from the nanometer to the millimeter scale for the detailed description of the relevant local and global phenomena. It describes the transient heat and fluid flow during the entire periodic cycle of a growing, detaching and rising bubble including the waiting time between two successive bubbles from a single nucleation site. The detailed analysis of the computed transient temperature profiles in wall and fluid give accurate information about the heat supply, temporal energy storage and local evaporation rates. (author)

    2017-01-01

    The aim of this study was to assess differences in fundamental motor skills (FMS) proficiency between boys and girls of each age group, independently, across the entire preschool period. Using the Movement Assessment Battery for Children-second edition, FMS proficiency was tested in 325 preschoolers (4.9 ± 1.1 y, range 3-6) using a cross-sectional design. Compared to boys of the same age, 3- and 4-year-old girls had greater total (p skill (p < .01), and balance scores (p < .05). There were no sex differences for total test or balance scores in 5- and 6-year-olds, but 6-year-old boys outperformed girls in aiming and catching (p < .001). These data not only agree with previous research in that sex differences in FMS proficiency exist in preschool children, but the data also show that differences may not be uniform throughout the whole preschool period when analyzing by age. To avoid under- or overestimating FMS proficiency and subsequently prescribing inaccurate motor intervention programs, FMS proficiency normative values should be age- and sex-specific throughout the entire preschool period.

  20. 3D View of Grand Canyon, Arizona

    Science.gov (United States)

    2000-01-01

    The Grand Canyon is one of North America's most spectacular geologic features. Carved primarily by the Colorado River over the past six million years, the canyon sports vertical drops of 5,000 feet and spans a 445-kilometer-long stretch of Arizona desert. The strata along the steep walls of the canyon form a record of geologic time from the Paleozoic Era (250 million years ago) to the Precambrian (1.7 billion years ago).The above view was acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument aboard the Terra spacecraft. Visible and near infrared data were combined to form an image that simulates the natural colors of water and vegetation. Rock colors, however, are not accurate. The image data were combined with elevation data to produce this perspective view, with no vertical exaggeration, looking from above the South Rim up Bright Angel Canyon towards the North Rim. The light lines on the plateau at lower right are the roads around the Canyon View Information Plaza. The Bright Angel Trail, which reaches the Colorado in 11.3 kilometers, can be seen dropping into the canyon over Plateau Point at bottom center. The blue and black areas on the North Rim indicate a forest fire that was smoldering as the data were acquired on May 12, 2000.Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of International Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, Calif., is the U.S. Science team leader; Moshe Pniel of JPL is the project manager. ASTER is the only high resolution imaging sensor on Terra. The primary goal of the ASTER mission is to obtain high-resolution image data in 14 channels over the entire land surface, as

  1. Perspective View with Landsat Overlay, Costa Rica

    Science.gov (United States)

    2002-01-01

    This perspective view shows the Caribbean coastal plain of Costa Rica, with the Cordillera Central rising in the background and the Pacific Ocean in the distance. The prominent river in the center of the image is the Rio Sucio, which merges with the Rio Sarapiqui at the bottom of the image and eventually joins with Rio San Juan on the Nicaragua border.Like much of Central America, Costa Rica is generally cloud covered so very little satellite imagery is available. The ability of the Shuttle Radar Topography Mission (SRTM) instrument to penetrate clouds and make three-dimensional measurements will allow generation of the first complete high-resolution topographic map of the entire region. These data were used to generate the image.This three-dimensional perspective view was generated using elevation data from SRTM and an enhanced false-color Landsat 7 satellite image. Colors are from Landsat bands 5, 4, and 2 as red, green and blue, respectively. Topographic expression is exaggerated two times.Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter resolution of most Landsat images and will substantially help in analyses of the large and growing Landsat image archive. The Landsat 7 Thematic Mapper image used here was provided to the SRTM by the United States Geological Survey, Earth Resources Observation Systems (EROS) Data Center, Sioux Falls, S.D.Elevation data used in this image was acquired by the SRTM aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices

    The aim of this prospective study was to evaluate the feasibility and establish normal values of functional right ventricle (RV) parameters as assessed in our four, long-axis view RV model using iRotate echocardiography. Furthermore, we evaluated the potential use of this model in patients with abnormally loaded RVs. One hundred and fifty-five healthy subjects aged 20-72 years (≥28 subjects per decile) were prospectively recruited. We used non-dedicated RV speckle-tracking software to test the feasibility and to establish normal range values of peak systolic global longitudinal RV strain (RV-GLS) from the RV free-walls (septum was excluded). Also normal range values for: dimensions, tricuspid annular plane systolic excursion (TAPSE) and tricuspid annular peak systolic velocity (TDI-S') were established. The feasibility of RV-GLS was 88, 84, and 62%, respectively, in the lateral, inferior, and anterior free wall. Mean RV-GLS normal values were -24.5 ± 4.9% for lateral wall and -25.4 ± 5.0% for anterior wall. Mean RV-GLS in the inferior wall was -23.2 ± 4.4% in the aortic (Ao) view and -20.7 ± 5.0% in the coronal (CV) view. The feasibility of mean RV-GLS was 100% in the anterior, lateral, and inferior walls in abnormally dilated RVs. The feasibility of all RV parameters assessed in the four-view iRotate model is good to excellent. Normal values for RV dimension and function of the anterior, inferior, and lateral RV walls have been established. Further studies and dedicated RV speckle-tracking software are warranted to discover the full potential of this new technique. Published on behalf of the European Society of Cardiology.

The general principle of the method is to (1 separate the root system into a small number of large pieces to reduce root overlap, (2 scan these pieces one by one, (3 analyze separate images with a root tracing software and (4 combine all tracings into a single vectorized root system. This method generates a rich dataset containing morphological, topological and geometrical information of entire root systems grown in rhizotrons. The utility of the method is illustrated with a detailed architectural analysis of a 20-day old maize root system, coupled with a spatial analysis of water uptake patterns.

    The Y chromosome is thought to be important for male reproduction. We have previously shown that, with the use of assisted reproduction, live offspring can be obtained from mice lacking the entire Y chromosome long arm. Here, we demonstrate that live mouse progeny can also be generated by using germ cells from males with the Y chromosome contribution limited to only two genes, the testis determinant factor Sry and the spermatogonial proliferation factor Eif2s3y. Sry is believed to function primarily in sex determination during fetal life. Eif2s3y may be the only Y chromosome gene required to drive mouse spermatogenesis, allowing formation of haploid germ cells that are functional in assisted reproduction. Our findings are relevant, but not directly translatable, to human male infertility cases.

    The aim of this study was to evaluate the perception of androstenone in pork from entire male pigs with different androstenone levels (High≥2mgkg -1 ; Medium 0.5-0.7mgkg -1 ) applying four different heating methods (vacuum, grill, oven and frying). Androstenone (AND) perception was analysed during and after cooking by a trained panel. During cooking, the highest score for AND odour (greatest perception) was obtained with the grill and vacuum, while frying was the best option for reducing its perception, which was judged to be imperceptible for androstenone medium level (Pperception, making it the best option for reducing both AND odour and flavour. In short, the use of different heating methods strongly affected AND perception. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2008-01-01

    Full Text Available Gangliogliomas (GG are mixed glioneuronal tumors of the central nervous system (CNS, occurring mostly in the pediatric population, with common sites being temporal lobes and less commonly in the frontal and parietal lobes. We report a case of a 7-year-old child who presented with bilateral visual defects for 6 months. Magnetic resonance imaging (MRI of the brain revealed an intensely enhancing mass lesion with calcification in the sellar and suprasellar region involving the optic chiasm and the left optic nerve. The mass showed almost bilaterally symmetrical diffuse spread along the optic tracts posteriorly and hypothalamus, temporal lobes, thalami and the basal ganglia. The lesion was radiologically indistinguishable from chiasmatic astrocytoma or a germ cell tumor but histopathological features were of a ganglioglioma. While a few optic apparatus gangliogliomas have been reported in the literature, such widespread diffuse involvement of the entire optico-chiasmal hypothalamic pathway is unusual.

    We study the 'quantized calculus' corresponding to the algebraic ideas related to 'twisted cyclic cohomology'. With very similar definitions and techniques, we define and study 'twisted entire cyclic cohomology' and the 'twisted Chern character' associated with an appropriate operator theoretic data called 'twisted spectral data', which consists of a spectral triple in the conventional sense of noncommutative geometry and an additional positive operator having some specified properties. Furthermore, it is shown that given a spectral triple (in the conventional sense) which is equivariant under the action of a compact matrix pseudogroup, it is possible to obtain a canonical twisted spectral data and hence the corresponding (twisted) Chern character, which will be invariant under the action of the pseudogroup, in contrast to the fact that the Chern character coming from the conventional noncommutative geometry need not be invariant under the above action.

    The aim of the present work was to investigate consumers' acceptability of bacons produced from entire males. Three different processing technologies (brine injection, dry salting with and without fermentation) were used. The raw materials had skatole levels from 0.04 to 0.43 mg/kg. The consumers...... showed little variation in liking scores for bacon produced with the different technologies. Assessors trained for recognizing skatole flavour, nevertheless identified the odour and flavour of skatole for more samples and technologies than the consumers did. However, trained sensory panellists could...... not identify taint in all dry salted bacons fermented with Staphylococcus xylosus even at a skatole level of 0.43 mg/kg fat. Sufficient liquid smoke in brine injected bacons masked the skatole flavour of bacons having 0.43 mg skatole/kg fat. (C) 2012 Elsevier Ltd. All rights reserved....

    Work related musculoskeletal disorders (MSDs), poor body postures, and low back injuries are the most common problems occurring in many industries including small-medium industries. This study presents assessment and evaluation of ergonomic postures of material handling worker. That evaluation was carried out using REBA (Rapid Entire Body Assessment). REBA is a technique to quantize the fatigue experienced by the worker while manually lifting loads. Fatigue due to abnormal work posture leads to complaints of labor-perceived pain. REBA methods were used to an assessment of working postures for the existing process by a procedural analysis of body postures involved. This study shows that parts of the body have a high risk of work are the back, neck, and upper arms with REBA score 9, so action should be taken as soon as possible. Controlling actions were implemented to those process with high risk then substantial risk reduction was achieved.

    Three-dimensional analysis of the entire sequence in ski jumping is recommended when studying the kinematics or evaluating performance. Camera-based systems which allow three-dimensional kinematics measurement are complex to set-up and require extensive post-processing, usually limiting ski jumping analyses to small numbers of jumps. In this study, a simple method using a wearable inertial sensors-based system is described to measure the orientation of the lower-body segments (sacrum, thighs, shanks) and skis during the entire jump sequence. This new method combines the fusion of inertial signals and biomechanical constraints of ski jumping. Its performance was evaluated in terms of validity and sensitivity to different performances based on 22 athletes monitored during daily training. The validity of the method was assessed by comparing the inclination of the ski and the slope at landing point and reported an error of -0.2±4.8°. The validity was also assessed by comparison of characteristic angles obtained with the proposed system and reference values in the literature; the differences were smaller than 6° for 75% of the angles and smaller than 15° for 90% of the angles. The sensitivity to different performances was evaluated by comparing the angles between two groups of athletes with different jump lengths and by assessing the association between angles and jump lengths. The differences of technique observed between athletes and the associations with jumps length agreed with the literature. In conclusion, these results suggest that this system is a promising tool for a generalization of three-dimensional kinematics analysis in ski jumping. Copyright © 2012 Elsevier Ltd.

  13. A DNA metabarcoding study of a primate dietary diversity and plasticity across its entire fragmented range.

    Directory of Open Access Journals (Sweden)

    Erwan Quéméré

    Full Text Available In tropical regions, most primary ecosystems have been replaced by mosaic landscapes in which species must cope with a large shift in the distribution of their habitat and associated food resources. Primates are particularly vulnerable to habitat modifications. Most species persist in small fragments surrounded by complex human-mediated matrices whose structure and connectivity may strongly influence their dispersal and feeding behavior. Behavioral plasticity appears to be a crucial parameter governing the ability of organisms to exploit the resources offered by new matrix habitats and thus to persist in fragmented habitats. In this study, we were interested in the dietary plasticity of the golden-crowned sifaka (Propithecus tattersalli, an endangered species of lemur, found only in the Daraina region in north-eastern Madagascar. We used a DNA-based approach combining the barcoding concept and Illumina next-generation sequencing to (i describe the species diet across its entire range and (ii evaluate the influence of landscape heterogeneity on diet diversity and composition. Faeces from 96 individuals were sampled across the entire species range and their contents were analyzed using the trnL metabarcoding approach. In parallel, we built a large DNA reference database based on a checklist of the plant species of the Daraina region. Our results suggest that golden-crowned sifakas exhibit remarkable dietary diversity with at least 130 plant species belonging to 80 genera and 49 different families. We highlighted an influence of both habitat type and openness on diet composition suggesting a high flexibility of foraging strategies. Moreover, we observed the presence of numerous cultivated and naturalized plants in the faeces of groups living in forest edge areas. Overall, our findings support our initial expectation that P. tattersalli is able to cope with the current level of alteration of the landscape and confirm our previous results on the

  14. Phase-partitioning in mixed-phase clouds - An approach to characterize the entire vertical column

    2017-12-01

    The characterization of the entire vertical profile of phase-partitioning in mixed-phase clouds is a challenge which can be addressed by synergistic profiling measurements with ground-based polarization lidars and cloud radars. While lidars are sensitive to small particles and can thus detect supercooled liquid (SCL) layers, cloud radar returns are dominated by larger particles (like ice crystals). The maximum lidar observation height is determined by complete signal attenuation at a penetrated optical depth of about three. In contrast, cloud radars are able to penetrate multiple liquid layers and can thus be used to expand the identification of cloud phase to the entire vertical column beyond the lidar extinction height, if morphological features in the radar Doppler spectrum can be related to the existence of SCL. Relevant spectral signatures such as bimodalities and spectral skewness can be related to cloud phase by training a neural network appropriately in a supervised learning scheme, with lidar measurements functioning as supervisor. The neural network output (prediction of SCL location) derived using cloud radar Doppler spectra can be evaluated with several parameters such as liquid water path (LWP) detected by microwave radiometer (MWR) and (liquid) cloud base detected by ceilometer or Raman lidar. The technique has been previously tested on data from Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) instruments in Barrow, Alaska and is in this study utilized for observations from the Leipzig Aerosol and Cloud Remote Observations System (LACROS) during the Analysis of the Composition of Clouds with Extended Polarization Techniques (ACCEPT) field experiment in Cabauw, Netherlands in Fall 2014. Comparisons to supercooled-liquid layers as classified by CLOUDNET are provided.

    The optical properties of thick InGaN epilayers, with compositions spanning the entire ternary range, are studied in detail. High structural quality, single phase InxGa1-xN (0001) films were grown heteroepitaxially by radio-frequency plasma assisted molecular-beam epitaxy on freestanding GaN substrates. Their emission characteristics were investigated by low temperature photoluminescence spectroscopy, whereas variable angle spectroscopic ellipsometry was applied to determine the complex dielectric function of the films, in the 0.55-4.0 eV photon range. Photoluminescence lines were intense and narrow, in the range of 100 meV for Ga-rich InGaN films (x 0.6). The composition dependence of the strain-free emission energy was expressed by a bowing parameter of b = 2.70 ± 0.12 eV. The films' optical dielectric function dispersion was obtained by the analysis of the ellipsometric data employing a Kramers-Kronig consistent parameterized optical model. The refractive index dispersion was obtained for alloys in the entire composition range, and the corresponding values at the band edge show a parabolic dependence on the InN mole fraction expressed by a bowing parameter of b = 0.81 ± 0.04. The bowing parameter describing the fundamental energy bandgap was deduced to be equal to 1.66 ± 0.07 eV, consistent with the ab initio calculations for statistically random (non-clustered) InGaN alloys.

    There is no consensus in literature about lifespan brain maturation and senescence, mainly because previous lifespan studies have been performed on restricted age periods and/or with a limited number of scans, making results instable and their comparison very difficult. Moreover, the use of nonharmonized tools and different volumetric measurements lead to a great discrepancy in reported results. Thanks to the new paradigm of BigData sharing in neuroimaging and the last advances in image processing enabling to process baby as well as elderly scans with the same tool, new insights on brain maturation and aging can be obtained. This study presents brain volume trajectory over the entire lifespan using the largest age range to date (from few months of life to elderly) and one of the largest number of subjects (N = 2,944). First, we found that white matter trajectory based on absolute and normalized volumes follows an inverted U-shape with a maturation peak around middle life. Second, we found that from 1 to 8-10 y there is an absolute gray matter (GM) increase related to body growth followed by a GM decrease. However, when normalized volumes were considered, GM continuously decreases all along the life. Finally, we found that this observation holds for almost all the considered subcortical structures except for amygdala which is rather stable and hippocampus which exhibits an inverted U-shape with a longer maturation period. By revealing the entire brain trajectory picture, a consensus can be drawn since most of the previously discussed discrepancies can be explained.

    View synthesis becomes a focus of attention of both the computer vision and computer graphics communities. It consists of creating novel images of a scene as it would appear from novel viewpoints. View synthesis can be used in a wide variety of applications such as video compression, graphics generation, virtual reality and entertainment. This paper addresses the following problem. Given a dense disparity map between two reference images, we would like to synthesize a novel view of the same scene associated with a novel viewpoint. Most of the existing work is relying on building a set of 3D meshes which are then projected onto the new image (the rendering process is performed using texture mapping). The advantages of our view synthesis approach are as follows. First, the novel view is specified by a rotation and a translation which are the most natural way to express the virtual location of the camera. Second, the approach is able to synthesize highly realistic images whose viewing position is significantly far away from the reference viewpoints. Third, the approach is able to handle the visibility problem during the synthesis process. Our developed framework has two main steps. The first step (analysis step) consists of computing the homography at infinity, the epipoles, and thus the parallax field associated with the reference images. The second step (synthesis step) consists of warping the reference image into a new one, which is based on the invariance of the computed parallax field. The analysis step is working directly on the reference views, and only need to be performed once. Examples of synthesizing novel views using either feature correspondences or dense disparity map have demonstrated the feasibility of the proposed approach.

    The Thermodynamics of Advanced Fuels - International Database (TAF-ID) Project was established in 2013 under the auspices of the NEA Nuclear Science Committee. The project was designed to make available a comprehensive, internationally recognised and quality-assured database of phase diagrams and thermodynamic properties of advanced nuclear fuels with a view to meeting specialised requirements for the development of advanced fuels for a future generation of nuclear reactors. Some of the specific technical objectives that this programme intends to achieve are to predict the solid, liquid and/or gas phases formed during fuel cladding chemical interactions under normal and accident conditions, to improve the control of the experimental conditions during the fabrication of fuel materials at high temperature, for example by predicting the vapour pressures of the elements (particularly of plutonium and the minor actinides) and to predict the evolution of the chemical composition of fuel under irradiation versus temperature and burn-up. This joint project, co-ordinated by the NEA, was established for an initial three-year period among nine organisations from six NEA member countries: Canada (AECL, RMCC, UOIT), France (CEA), Japan (JAEA, CRIEPI), the Netherlands (NRG), the Republic of Korea (KAERI) and the United States (US DOE). It is entirely funded by the nine signatories of the project. (authors)

  20. Differentiation of cartilaginous anlage in entire embryonic mouse limbs cultured in a rotating bioreactor.

    Duke, P.; Oakley, C.; Montufar-Solis, D.

    The embryonic mammalian limb is sensitive both in vivo and in vitro to changes in gravitational force. Hypergravity of centrifugation and microgravity of space decreased size of elements due to precocious or delayed chondrogenesis respectively. In recapitulating spaceflight experiments, premetatarsals were cultured in suspension in a low stress, low sheer rotating bioreactor, and found to be shorter than those cultured in standard culture dishes, and cartilage development was delayed. This study only measured length of the metatarsals, and did not account for possible changes in width and/or in form of the skeletal elements. Shorter cartilage elements in limbbuds cultured in the bioreactor may be due to the ability of the system to reproduce a more in vivo 3D shape than traditional organ cultures. Tissues subjected to traditional organ cultures become flattened by their own weight, attachment to the filter, and restrictions imposed by nutrient diffusion. The purpose of the current experiment was to determine if entire limb buds could be successfully cultured in the bioreactor, and to compare the effects on 3D shape with that of culturing in a culture dish system. Fore and hind limbs from E11-E13 ICR mouse embryos were placed either in the bioreactor, in Trowell culture, or fixed as controls. Limbbuds were cultured for six days, fixed, and processed either as whole mounts or embedded for histology. Qualitative analysis revealed that the Trowell culture specimens were flattened, while bioreactor culture specimens had a more in vivo-like 3D limb shape. Sections of limbbuds from both types of cultures had excellent cartilage differentiation, with apparently more cell maturation, and hypertrophy in the specimens cultured in the bioreactor. Morphometric quantitation of the cartilaginous elements for comparisons of the two culture systems was complicated due to some limb buds fusing together during culture. This problem was especially noticeable in the younger limbs, and

    Mechanisms involved in development of the embryonic limb have remained the same throughout eons of genetic and environmental evolution under Earth gravity (lg). During the spaceflight era it has been of interest to explore the ancient theory that form of the skeleton develops in response to gravity, and that changes in gravitational forces can change the developmental pattern of the limb. This has been shown in vivo and in vitro, allowing the hypergravity of centrifugation and microgravity of space to be used as tools to increase our knowledge of limb development. In recapitulations of spaceflight experiments, premetatarsals were cultured in suspension in a bioreactor, and found to be shorter and less differentiated than those cultured in standard culture dishes. This study only measured length of the metatarsals, and did not account for possible changes due to the skeletal elements having a more in vivo 3D shape while in suspension vs. flattened tissues compressed by their own weight. A culture system with an outcome closer to in vivo and that supports growth of younger limb buds than traditional systems will allow studies of early Hox gene expression, and contribute to the understanding of very early stages of development. The purpose of the current experiment was to determine if entire limb buds could be cultured in the bioreactor, and to compare the growth and differentiation with that of culturing in a culture dish system. Fore and hind limbs from E11-E13 ICR mouse embryos were cultured for six days, either in the bioreactor or in center-well organ culture dishes, fixed, and embedded for histology. E13 specimens grown in culture dishes were flat, while bioreactor culture specimens had a more in vivo-like 3D limb shape. Sections showed excellent cartilage differentiation in both culture systems, with more cell maturation, and hypertrophy in the specimens cultured in the bioreactor.

    Estimating the impacts of global and local threats on coral reefs requires monitoring reef health and measuring coral growth and calcification rates at different time scales. This has traditionally been mostly performed in short-term experimental studies in which coral fragments were grown in the laboratory or in the field but measured ex situ. Practical techniques in which growth and measurements are performed over the long term in situ are rare. Apart from photographic approaches, weight increment measurements have also been applied. Past buoyant weight measurements under water involved a complicated and little-used apparatus. We introduce a new method that combines previous field and laboratory techniques to measure the buoyant weight of entire, transplanted corals under water. This method uses an electronic balance fitted into an acrylic glass underwater housing and placed atop of an acrylic glass cube. Within this cube, corals transplanted onto artificial bases can be attached to the balance and weighed at predetermined intervals while they continue growth in the field. We also provide a set of simple equations for the volume and weight determinations required to calculate net growth rates. The new technique is highly accurate: low error of weight determinations due to variation of coral density (corals. We outline a transplantation technique for properly preparing corals for such long-term in situ experiments and measurements.

    This research investigated the capacities of recycled aggregate concrete adopting entire concrete waste reuse model in degrading NO 2. Two major issues within environmental sustainability were addressed: concrete waste reuse rate and mitigation of hazards substances in the polluted air. The study consisted of two stages: identification of proper replacement rates of recycled concrete wastes in new concrete mixture design, and the evaluation of photocatalytic performance of recycled aggregate concrete in degrading NO 2 . It was found that replacement rates up to 3%, 30%, and 50% for recycled power, recycled fine aggregate, and recycled coarse aggregate respectively could be applied in concrete mixture design without deteriorating concrete strength. Recycled aggregates contained both positive attributes ("internal curing") and negative effects (e.g., lower hardness) to concrete properties. It was found that 30%-50% of natural coarse aggregate replaced by recycled coarse aggregates coated with TiO 2 would significantly improve the photocatalytic performance of concrete measured by degradation rate of NO 2 . Micro-structures of recycled aggregates observed under microscope indicated that soaking recycled aggregates in TiO 2 solution resulted in whiskers that filled the porosity within recycled aggregates which enhanced concrete strength.

    Hemophilia A is a common X-linked recessive disorder of bleeding caused by deleterious mutations in the gene for clotting factor VIII. The large size of the factor VIII gene, the high frequency of de novo mutations and its tissue-specific expression complicate the detection of mutations. We have used a combination of RT-PCR of ectopic factor VIII transcripts and genomic DNA-PCRs to amplify the entire essential sequence of the factor VIII gene. This is followed by chemical mismatch cleavage analysis and direct sequencing in order to facilitate a comprehensive search for mutations. We describe the characterization of nine potentially pathogenic mutations, six of which are novel. In each case, a correlation of the genotype with the observed phenotype is presented. In order to evaluate the pathogenicity of the five missense mutations detected, we have analyzed them for evolutionary sequence conservation and for their involvement of sequence motifs catalogued in the PROSITE database of protein sites and patterns.

    Inborn preference for palatable energy-dense food is thought to be an evolutionary adaptation. One way this preference manifests itself is through the control of visual attention. In the present study, we investigated how attentional capture is influenced by changes in naturally occurring goal-states, in this case desire for energy-dense foods (typically high fat and/or high sugar). We demonstrate that even when distractors are entirely irrelevant, participants were significantly more distracted by energy-dense foods compared with non-food objects and even low-energy foods. Additionally, we show the lability of these goal-states by having a separate set of participants consume a small amount of calorie-dense food prior to the task. The amount of distraction by the energy-dense food images in this case was significantly reduced and no different than distraction by images of low-energy foods and images of non-food objects. While naturally occurring goal-states can be difficult to ignore, they also are highly flexible.

  6. Intraspecific variation in social organization by genetic variation, developmental plasticity, social flexibility or entirely extrinsic factors.

    Previously, it was widely believed that each species has a specific social organization, but we know now that many species show intraspecific variation in their social organization. Four different processes can lead to intraspecific variation in social organization: (i) genetic variation between individuals owing to local adaptation (between populations) or evolutionarily stable strategies within populations; (ii) developmental plasticity evolved in long-term (more than one generation) unpredictable and short-term (one generation) predictable environments, which is mediated by organizational physiological effects during early ontogeny; (iii) social flexibility evolved in highly unpredictable environments, which is mediated by activational physiological effects in adults; (iv) entirely extrinsic factors such as the death of a dominant breeder. Variation in social behaviour occurs between individuals in the case of genetic variation and developmental plasticity, but within individuals in the case of social flexibility. It is important to study intraspecific variation in social organization to understand the social systems of species because it reveals the mechanisms by which species can adapt to changing environments, offers a useful tool to study the ultimate and proximate causes of sociality, and is an interesting phenomenon by itself that needs scientific explanation.

    The paper focuses on the analysis of an industrial ceramic kiln in order to improve the energy efficiency and thus the fuel consumption and the corresponding carbon dioxide emissions. A lumped and distributed parameter model of the entire system is constructed to simulate the performance of the kiln under actual operating conditions. The model is able to predict accurately the temperature distribution along the different modules of the kiln and the operation of the many natural gas burners employed to provide the required thermal power. Furthermore, the temperature of the tiles is also simulated so that the quality of the final product can be addressed by the modelling. Numerical results are validated against experimental measurements carried out on a real ceramic kiln during regular production operations. The developed numerical model demonstrates to be an efficient tool for the investigation of different design solutions for the kiln's components. In addition, a number of control strategies for the system working conditions can be simulated and compared in order to define the best trade off in terms of fuel consumption and product quality. In particular, the paper analyzes the effect of a new burner type characterized by internal heat recovery capability aimed at improving the energy efficiency of the ceramic kiln. The fuel saving and the relating reduction of carbon dioxide emissions resulted in the order of 10% when compared to the standard burner. Copyright © 2017 Elsevier Ltd. All rights reserved.

  8. Postmortem diffusion MRI of the entire human spinal cord at microscopic resolution

    Directory of Open Access Journals (Sweden)

    Full Text Available The human spinal cord is a central nervous system structure that plays an important role in normal motor and sensory function, and can be affected by many debilitating neurologic diseases. Due to its clinical importance, the spinal cord is frequently the subject of imaging research. Common methods for visualizing spinal cord anatomy and pathology include histology and magnetic resonance imaging (MRI, both of which have unique benefits and drawbacks. Postmortem microscopic resolution MRI of fixed specimens, sometimes referred to as magnetic resonance microscopy (MRM, combines many of the benefits inherent to both techniques. However, the elongated shape of the human spinal cord, along with hardware and scan time limitations, have restricted previous microscopic resolution MRI studies (both in vivo and ex vivo to small sections of the cord. Here we present the first MRM dataset of the entire postmortem human spinal cord. These data include 50 μm isotropic resolution anatomic image data and 100 μm isotropic resolution diffusion data, made possible by a 280 h long multi-segment acquisition and automated image segment composition. We demonstrate the use of these data for spinal cord lesion detection, automated volumetric gray matter segmentation, and quantitative spinal cord morphometry including estimates of cross sectional dimensions and gray matter fraction throughout the length of the cord.

    Purpose: Craniospinal radiation (CSRT) followed by a boost to the entire posterior fossa (PF) is standard post-operative therapy for patients with medulloblastoma. A large proportion of recurrences after treatment are local with approximately 50-70% of recurrences occurring in the PF. It is unclear, however, whether these failures are occurring in the original tumor bed, or outside the tumor bed but still within the PF. With improved diagnostic imaging, better definition of tumor volumes, and the use of 3D conformal therapy, we may be able to restrict the boost volume to the tumor bed plus a margin without compromising local control. This retrospective study analyzes the patterns of failure within the PF of a series of patients treated with radiation therapy (RT). Methods: From (7(86)) through (2(96)), 27 of 114 (24%) patients > 18 mo and < 18 yr with medulloblastoma, who were treated at the University of Michigan and Children's Hospital of Philadelphia, with RT following surgical resection were found to have a recurrence. RT consisted of CSRT followed by a boost to the entire posterior fossa. Patient's preoperative MRI and/or CT studies were used to compare the original tumor volume with the specific region of local relapse. Failure was defined as MRI or CT evidence of recurrence or positive cerebrospinal fluid cytology. Relapse was scored as local, if it was within the original tumor bed and regional, if it was outside of the tumor bed but still within the PF. Results: The median age of the patients was 8.6 years. Three patients were < 3 years old. (21(27)) had disease localized to the PF. (19(21)) patients received chemotherapy during their treatment regimen; 6 patients did not have information on systemic treatment. The median dose of RT to the craniospinal axis was 32.5 Gy and to the PF was 55.2 Gy. The median time to recurrence was 19.5 months. Local failure within the tumor bed as any component of first failure occurred in 52% ((14(27))) of all failures but

    The contribution of animal breeding to changes in animal performance is well documented across a range of species. Once genetic variation in a trait exists, then breeding to improve the characteristics of that trait is possible, if so desired. Considerable genetic variation exists in a range of meat quality attributes across a range of species. The genetic variation that exists for meat quality is as large as observed for most performance traits; thus, within a well-structured breeding program, rapid genetic gain for meat quality could be possible. The rate of genetic gain can be augmented through the integration of DNA-based technologies into the breeding program; such DNA-based technologies should, however, be based on thousands of DNA markers dispersed across the entire genome. Genetic and genomic technologies can also have beneficial impact outside the farm gate as a tool to segregate carcasses or meat cuts based on expected meat quality features.

    Landsat's continuing record of the thermal state of the earth's surface represents the only long term (1982 to the present) global record with spatial scales appropriate for human scale studies (i.e., tens of meters). Temperature drives many of the physical and biological processes that impact the global and local environment. As our knowledge of, and interest in, the role of temperature on these processes have grown, the value of Landsat data to monitor trends and process has also grown. The value of the Landsat thermal data archive will continue to grow as we develop more effective ways to study the long term processes and trends affecting the planet. However, in order to take proper advantage of the thermal data, we need to be able to convert the data to surface temperatures. A critical step in this process is to have the entire archive completely and consistently calibrated into absolute radiance so that it can be atmospherically compensated to surface leaving radiance and then to surface radiometric temperature. This paper addresses the methods and procedures that have been used to perform the radiometric calibration of the earliest sizable thermal data set in the archive (Landsat 4 data). The completion of this effort along with the updated calibration of the earlier (1985 1999) Landsat 5 data, also reported here, concludes a comprehensive calibration of the Landsat thermal archive of data from 1982 to the present

    Probabilistic estimates of future water levels and river discharge are usually simulated with hydrologic models using ensemble weather forecasts as main inputs. As hydrologic models are imperfect and the meteorological ensembles tend to be biased and underdispersed, the ensemble forecasts for river runoff typically are biased and underdispersed, too. Thus, in order to achieve both reliable and sharp predictions statistical postprocessing is required. In this work Bayesian model averaging (BMA) is applied to statistically postprocess ensemble runoff raw forecasts for a catchment in Switzerland, at lead times ranging from 1 to 240 h. The raw forecasts have been obtained using deterministic and ensemble forcing meteorological models with different forecast lead time ranges. First, BMA is applied based on mixtures of univariate normal distributions, subject to the assumption of independence between distinct lead times. Then, the independence assumption is relaxed in order to estimate multivariate runoff forecasts over the entire range of lead times simultaneously, based on a BMA version that uses multivariate normal distributions. Since river runoff is a highly skewed variable, Box-Cox transformations are applied in order to achieve approximate normality. Both univariate and multivariate BMA approaches are able to generate well calibrated probabilistic forecasts that are considerably sharper than climatological forecasts. Additionally, multivariate BMA provides a promising approach for incorporating temporal dependencies into the postprocessed forecasts. Its major advantage against univariate BMA is an increase in reliability when the forecast system is changing due to model availability.

    The koala retrovirus (KoRV) is the only retrovirus known to be in the midst of invading the germ line of its host species. Hybridization capture and next generation sequencing were used on modern and museum DNA samples of koala (Phascolarctos cinereus) to examine ca. 130 years of evolution across the full KoRV genome. Overall, the entire proviral genome appeared to be conserved across time in sequence, protein structure and transcriptional binding sites. A total of 138 polymorphisms were detected, of which 72 were found in more than one individual. At every polymorphic site in the museum koalas, one of the character states matched that of modern KoRV. Among non-synonymous polymorphisms, radical substitutions involving large physiochemical differences between amino acids were elevated in env, potentially reflecting anti-viral immune pressure or avoidance of receptor interference. Polymorphisms were not detected within two functional regions believed to affect infectivity. Host sequences flanking proviral integration sites were also captured; with few proviral loci shared among koalas. Recently described variants of KoRV, designated KoRV-B and KoRV-J, were not detected in museum samples, suggesting that these variants may be of recent origin. PMID:24752422

    Hydroponic isotope labeling of entire plants (HILEP) combines hydroponic plant cultivation and metabolic labeling with stable isotopes using (15)N-containing inorganic salts to label whole and mature plants. Employing (15)N salts as the sole nitrogen source for HILEP leads to the production of healthy-looking plants which contain (15)N proteins labeled to nearly 100%. Therefore, HILEP is suitable for quantitative plant proteomic analysis, where plants are grown in either (14)N- or (15)N-hydroponic media and pooled when the biological samples are collected for relative proteome quantitation. The pooled (14)N-/(15)N-protein extracts can be fractionated in any suitable way and digested with a protease for shotgun proteomics, using typically reverse phase liquid chromatography nanoelectrospray ionization tandem mass spectrometry (RPLC-nESI-MS/MS). Best results were obtained with a hybrid ion trap/FT-MS mass spectrometer, combining high mass accuracy and sensitivity for the MS data acquisition with speed and high-throughput MS/MS data acquisition, increasing the number of proteins identified and quantified and improving protein quantitation. Peak processing and picking from raw MS data files, protein identification, and quantitation were performed in a highly automated way using integrated MS data analysis software with minimum manual intervention, thus easing the analytical workflow. In this methodology paper, we describe how to grow Arabidopsis plants hydroponically for isotope labeling using (15)N salts and how to quantitate the resulting proteomes using a convenient workflow that does not require extensive bioinformatics skills.

Advanced LabVIEW Labs presents a series of chapters devoted to not only introducing the reader to LabVIEW, but also to the concepts necessary for writing a successful computer pro- gram. Each chapter is an assignment for the student and is suitable for a ten week course. The first topic introduces the while loop and waveform chart VI'S. After learning how to launch LabVIEW, the student then leans how to use LabVIEW functions such as sine and cosine. The beauty of thk and subsequent chapters, the student is introduced immediately to computer-based instruction by learning how to display the results in graph form on the screen. At each point along the way, the student is not only introduced to another LabVIEW operation, but also to such subjects as spread sheets for data storage, numerical integration, Fourier transformations', curve fitting algorithms, etc. The last few chapters conclude with the purpose of the learning module, and that is, com- puter-based instrumentation. Computer-based laboratory projects such as analog-to-digital con- version, digitizing oscilloscopes treated. Advanced Lab VIEW Labs finishes with a treatment on GPIB interfacing and finally, the student is asked to create an operating VI for temperature con- trol. This is an excellent text, not only as an treatise on LabVIEW but also as an introduction to computer programming logic. All programmers, who are struggling to not only learning how interface computers to instruments, but also trying understand top down programming and other programming language techniques, should add Advanced Lab-VIEW Labs to their computer library

    To describe how people who use wheelchairs participate and move at home and in the community over an entire yearlong period, including during times of inclement weather conditions. Longitudinal mixed-methods research study. Urban community in Canada. People who use a wheelchair for home and community mobility (N=11). Not applicable. Use of a global positioning system (GPS) tracker for movement in community (number of trips per day), use of accelerometer for bouts of wheeling mobility (number of bouts per day, speed, distance, and duration), prompted recall interviews to identify supports and barriers to mobility and participation. More trips per day were taken during the summer (P= .03) and on days with no snow and temperatures above 0°C. Participants reliant on public transportation demonstrated more weather-specific changes in their trip patterns. The number of daily bouts of mobility remained similar across seasons; total daily distance wheeled, duration, and speed were higher on summer days, days with no snow, and days with temperatures above 0°C. A higher proportion of outdoor wheeling bouts occurred in summer (P=.02) and with temperatures above 0°C (P=.03). Inaccessible public environments were the primary barrier to community mobility and participation; access to social supports and private transportation were the primary supports. Objective support is provided for the influence of various seasonal weather conditions on community mobility and participation for people who use a wheelchair. Longitudinal data collection provided a detailed understanding of the patterns of, and influences on, wheelchair mobility and participation within wheelchair users' own homes and communities.

  18. Building theories of knowledge translation interventions: Use the entire menu of constructs

    Full Text Available Abstract Background In the ongoing effort to develop and advance the science of knowledge translation (KT, an important question has emerged around how theory should inform the development of KT interventions. Discussion Efforts to employ theory to better understand and improve KT interventions have until recently mostly involved examining whether existing theories can be usefully applied to the KT context in question. In contrast to this general theory application approach, we propose a ‘menu of constructs’ approach, where individual constructs from any number of theories may be used to construct a new theory. By considering the entire menu of available constructs, rather than limiting choice to the broader level of theories, we can leverage knowledge from theories that would never on their own provide a complete picture of a KT intervention, but that nevertheless describe components or mechanisms relevant to it. We can also avoid being forced to adopt every construct from a particular theory in a one-size-fits-all manner, and instead tailor theory application efforts to the specifics of the situation. Using audit and feedback as an example KT intervention strategy, we describe a variety of constructs (two modes of reasoning, cognitive dissonance, feed forward, desirable difficulties and cognitive load, communities of practice, and adaptive expertise from cognitive and educational psychology that make concrete suggestions about ways to improve this class of intervention. Summary The ‘menu of constructs’ notion suggests an approach whereby a wider range of theoretical constructs, including constructs from cognitive theories with scope that makes the immediate application to the new context challenging, may be employed to facilitate development of more effective KT interventions.

  20. Effects of Ankle Arthrodesis on Biomechanical Performance of the Entire Foot.

    Full Text Available Ankle arthrodesis is one popular surgical treatment for ankle arthritis, chronic instability, and degenerative deformity. However, complications such as foot pain, joint arthritis, and bone fracture may cause patients to suffer other problems. Understanding the internal biomechanics of the foot is critical for assessing the effectiveness of ankle arthrodesis and provides a baseline for the surgical plan. This study aimed to understand the biomechanical effects of ankle arthrodesis on the entire foot and ankle using finite element analyses. A three-dimensional finite element model of the foot and ankle, involving 28 bones, 103 ligaments, the plantar fascia, major muscle groups, and encapsulated soft tissue, was developed and validated. The biomechanical performances of a normal foot and a foot with ankle arthrodesis were compared at three gait instants, first-peak, mid-stance, and second-peak.Changes in plantar pressure distribution, joint contact pressure and forces, von Mises stress on bone and foot deformation were predicted. Compared with those in the normal foot, the peak plantar pressure was increased and the center of pressure moved anteriorly in the foot with ankle arthrodesis. The talonavicular joint and joints of the first to third rays in the hind- and mid-foot bore the majority of the loading and sustained substantially increased loading after ankle arthrodesis. An average contact pressure of 2.14 MPa was predicted at the talonavicular joint after surgery and the maximum variation was shown to be 80% in joints of the first ray. The contact force and pressure of the subtalar joint decreased after surgery, indicating that arthritis at this joint was not necessarily a consequence of ankle arthrodesis but rather a progression of pre-existing degenerative changes. Von Mises stress in the second and third metatarsal bones at the second-peak instant increased to 52 MPa and 34 MPa, respectively, after surgery. These variations can provide

    Previously we demonstrated that an entire bacterial operon (the PRN operon) is expressible in plants when driven by the Tomato -yellow-leaf-curl-virus (TYLCV) -derived universal vector IL-60.Petroleum-derived plastics are not degradable, and are therefore harmful to the environment. Fermentation of bacteria carrying operons for polyhydroxyalkanoates (PHAs) produces degradable bioplastics which are environmentally friendly. However, bacterial production of bioplastics is not cost-effective, and attention is turning to their production in plants. Such "green" plastics would be less expensive and environmentally friendly. Hence, attempts are being made to substitute petroleum-derived plastics with "green" plastics. However, transformation of plants with genes of operons producing bioplastics has deleterious effects. Transformation of plastids does not cause deleterious effects, however it is a complicated procedures. We have developed another TYLCV-based vector (SE100) and show that yet another bacterial operon (the phaCAB operon) when driven by SE100 is also expressed in plants. We employed the combination of SE100 and the phaCAB operon to drive the operon to the plastids and produce in plants a biodegradable plastic [polyhydroxybutyrate (PHB)].Here we indicate that the bacterial operon (phaCAB), when driven by the newly developed universal plant vector SE100 is directed to chloroplasts and produces in plants PHB, a leading PHA. The PHB-producing plants circumvent the need for complicated technical procedures. The viral vector system SE100 facilitated the production of the bio-plastic poly-3-hydroxybutyrate. This was achieved by using the full pha-CAB operon indicating that TYLCV based system can transcribe and translate genes from bacterial operons controlled by a single cis element. Our data hints to the participation of the chloroplasts in these processes.

    Experimental study is performed on the mean stress relaxation effects of the Chinese new piping material, 0Cr18Ni10Ti steel. Six sets of specimens are respectively fatigued under a strain-controlled mode with the six straining ratios (R ε ) of -1, -0.52, -0.22, 0.029, 0.18, and 0.48 by an improved test method implied with an maximum likelihood statistical principle. The test results reveal that the material exhibits a Masing behaviour and, surprisingly, involves an entire mean stress relaxation. A challenge is then emerging to the traditional same treat of straining ratio and stressing ratio (R σ ) in fatigue analysis and assessment. There is still no effective method to describe this kind of relaxation. However the R ε effects can represent the relaxation effects appropriately by investigation on the material random cyclic stress-strain (σ-ε) relations and strain-life (ε-N) relations with different R ε . The intrinsic randomness of the responses is taken into account on a probabilistic sense. Significant differences are observed of the material cyclic responses under different R ε . For σ-ε relations, the R ε effects act as a decreasing trend to the stress amplitudes with the increasing survival probability and confidence. The strongest effect appears at R ε of 0.029, and a weaker one acts as R ε is far away from zero. For ε-N relations, R ε greater than zero exhibits a positive effect on the fatigue lives of about 1.3 to 1.6 times under a survival probability of 0.999 and a confidence of 95%, while a negative effect is exhibited in case of R ε less than zero. Present work indicates that systematic researches should be made to give a reasonable fatigue prediction in service on a basis of cyclic strain inspection of structures. (authors)

    We encountered a patient with herpes simplex encephalitis whose cerebral lesions were studied by repeated CT scannings during his entire clinical course. The purpose of this paper is to report the earliest lesions of the brain as revealed by CT scans. A 63-year-old man was admitted to our clinic complaining of headache, nausea, fever, and disorientation. On admission, a physical examination showed a high fever, while a neurological examination revealed a stiff neck, a positive Kernig's sign, and disorientation. Laboratory examinations revealed a pleocytosis of the cerebrospinal fluid. Electroencephalograms showed the so-called ''periodic sharp-and-slow-waves complex''. The complement fixation titer for herpes simplex virus was x32 in the serum and x128 in the cerebrospinal fluid, suggesting the diagnosis of herpes simplex encephalitis. We treated him with adenine arabinoside and gamma-globulin, but the patient did not recover; rather, he died of pneumonia and gastrointestinal bleeding three months later. Plain CT scans taken on the 12th day after the onset revealed a low-density area with signs of a slight mass in the region from the right island of Reil to the right uncus. Contrast-enhanced CT scans revealed an irregular enhancement in the low-density area. CT scans taken on the 19th day after the onset showed an extensive low-density area with a streak-like enhancement in the right temporal lobe, which is in aggreement with the findings reported by others as characteristic CT findings for herpes simplex encephalitis. In order to make an early diagnosis of a patient, we should pay attention to a low-density area with an irregular contrast enhancement in the region from the island of Reil to the uncus on a CT scan.

    In this paper we describe the development and validation of a 30m resolution hydrodynamic model covering the entire conterminous United States. The model can be used to simulate inundation and water depths resulting from either return period flows (so equivalent to FEMA Flood Insurance Rate Maps), hindcasts of historic events or forecasts of future river flow from a rainfall-runoff or land surface model. As topographic data the model uses the U.S. Geological Survey National Elevation Dataset or NED, and return period flows are generated using a regional flood frequency analysis methodology (Smith et al., 2015. Worldwide flood frequency estimation. Water Resources Research, 51, 539-553). Flood defences nationwide are represented using data from the US Army Corps of Engineers. Using these data flows are simulated using an explicit and highly efficient finite difference solution of the local inertial form of the Shallow Water equations identical to that implemented in the LISFLOOD-FP model. Even with this efficient numerical solution a simulation at this resolution over a whole continent is a huge undertaking, and a variety of High Performance Computing technologies therefore need to be employed to make these simulations possible. The size of the output datasets is also challenging, and to solve this we use the GIS and graphical display functions of Google Earth Engine to facilitate easy visualisation and interrogation of the results. The model is validated against the return period flood extents contained in FEMA Flood Insurance Rate Maps and real flood event data from the Texas 2015 flood event which was hindcast using the model. Finally, we present an application of the model to the Upper Mississippi river basin where simulations both with and without flood defences are used to determine floodplain areas benefitting from protection in order to quantify the benefits of flood defence spending.

    Full Text Available Abstract Background Medical spending on psychiatric hospitalization has been reported to impose a tremendous socio-economic burden on many developed countries with public health insurance programmes. However, there has been no in-depth study of the factors affecting psychiatric inpatient medical expenditures and differentiated these factors across different types of public health insurance programmes. In view of this, this study attempted to explore factors affecting medical expenditures for psychiatric inpatients between two public health insurance programmes covering the entire South Korean population: National Health Insurance (NHI and National Medical Care Aid (AID. Methods This retrospective, cross-sectional study used a nationwide, population-based reimbursement claims dataset consisting of 1,131,346 claims of all 160,465 citizens institutionalized due to psychiatric diagnosis between January 2005 and June 2006 in South Korea. To adjust for possible correlation of patients characteristics within the same medical institution and a non-linearity structure, a Box-Cox transformed, multilevel regression analysis was performed. Results Compared with inpatients 19 years old or younger, the medical expenditures of inpatients between 50 and 64 years old were 10% higher among NHI beneficiaries but 40% higher among AID beneficiaries. Males showed higher medical expenditures than did females. Expenditures on inpatients with schizophrenia as compared to expenditures on those with neurotic disorders were 120% higher among NHI beneficiaries but 83% higher among AID beneficiaries. Expenditures on inpatients of psychiatric hospitals were greater on average than expenditures on inpatients of general hospitals. Among AID beneficiaries, institutions owned by private groups treated inpatients with 32% higher costs than did government institutions. Among NHI beneficiaries, inpatients medical expenditures were positively associated with the proportion of

    Limited proteolysis of the 153-residue chain of horse apomyoglobin (apoMb) by thermolysin results in the selective cleavage of the peptide bond Pro88-Leu89. The N-terminal (residues 1-88) and C-terminal (residues 89-153) fragments of apoMb were isolated to homogeneity and their conformational and association properties investigated in detail. Far-UV circular dichroism (CD) measurements revealed that both fragments in isolation acquire a high content of helical secondary structure, while near-UV CD indicated the absence of tertiary structure. A 1:1 mixture of the fragments leads to a tight noncovalent protein complex (1-88/89-153, nicked apoMb), characterized by secondary and tertiary structures similar to those of intact apoMb. The apoMb complex binds heme in a nativelike manner, as given by CD measurements in the Soret region. Second-derivative absorption spectra in the 250-300 nm region provided evidence that the degree of exposure of Tyr residues in the nicked species is similar to that of the intact protein at neutral pH. Also, the microenvironment of Trp residues, located in positions 7 and 14 of the 153-residue chain of the protein, is similar in both protein species, as given by fluorescence emission data. Moreover, in analogy to intact apoMb, the nicked protein binds the hydrophobic dye 1-anilinonaphthalene-8-sulfonate (ANS). Taken together, our results indicate that the two proteolytic fragments 1-88 and 89-153 of apoMb adopt partly folded states characterized by sufficiently nativelike conformational features that promote their specific association and mutual stabilization into a nicked protein species much resembling in its structural features intact apoMb. It is suggested that the formation of a noncovalent complex upon fragment complementation can mimic the protein folding process of the entire protein chain, with the difference that the folding of the complementary fragments is an intermolecular process. In particular, this study emphasizes the

    Uertsch rockglacier (46.61° N, 9.84°E, ca. 2500m asl.) is a tongue-shaped 300m x 100m landform at the head of a small high mountain valley in the Eastern Swiss Alps. Located at the lower end of possible permafrost existence, the rockglacier shows indications of permafrost decay although borehole temperature measurements exhibit an at least partly occurrence of permanently frozen subsurface conditions. To delimit the extent of the frozen area and to characterize subsurface structures, we performed three adjacent 3-D Electrical Resistivity Imaging (ERI) surveys consisting of data from altogether 138 merged 2-D profiles, covering nearly the entire rockglacier by an investigation area of more than 2.5 ha. More than 47000 data points of Wenner-Schlumberger and Dipol-Dipol electrode arrays grant sufficient data coverage. Ground-truthing was achieved through borehole temperature measurements and multiple comparative ground-penetrating radar (GPR) and seismic refraction tomography (SRT) surveys. Results show that the rockglacier today lacks a consistent permafrost table and only shows a patchy permafrost distribution. Several structures differing in geometry and electric resistivity show a complex pattern of ice-rich, ice-poor and ice-free areas. We could identify glacial influence in the root zone of the rockglacier, where a 3200m2 perennial surface ice field is visible. In a downslope direction, a shallow layer of high resistivity values, which is limited to the shallow subsurface, follows the ice field and indicates a genesis by refreezing meltwater. The central part of the rockglacier also shows traces of glacial interaction by the occurrence of a several meters thick buried ice patch in the shallow subsurface at a marginal position. Next to this position, in an area where longitudinal surface ridges are exposed, modelled resistivity values indicate frozen conditions with relatively low ice content, limited to the shallow subsurface. We assume that these structures

    The National Aeronautics and Space Administration s (NASA's) Space Launch System (SLS) will contribute a new capability for human space flight and scientific missions beyond low-Earth orbit. The SLS Program, managed at NASA s Marshall Space Fight Center, will develop the heavy-lift vehicle that will launch the Orion Multi-Purpose Crew Vehicle (MPCV), equipment, supplies, and major science missions. Orion will carry crews to space, provide emergency abort capability, sustain the crew during space travel, and provide safe reentry from deep-space return velocities. Supporting Orion s first autonomous flight to lunar orbit and back in 2017 and its first crewed flight in 2021, the SLS ultimately offers a flexible platform for both human and scientific exploration. The SLS plan leverages legacy infrastructure and hardware in NASA s inventory, as well as continues with advanced propulsion technologies now in development, to deliver an initial 70 metric ton (t) lift capability in 2017, evolving to a 130-t capability after 2021, using a block upgrade approach. This paper will give an overview of the SLS design and management approach against a backdrop of the missions it will support. It will detail the plan to deliver the initial SLS capability to the launch pad in the near term, as well as summarize the innovative approaches the SLS team is applying to deliver a safe, affordable, and sustainable long-range capability for entirely new missions opening a new realm of knowledge and a world of possibilities for multiple partners. Design reference missions that the SLS is being planned to support include asteroids, Lagrange Points, and Mars, among others. The Agency is developing its mission manifest in parallel with the development of a heavy-lift flagship that will dramatically increase total lift and volume capacity beyond current launch vehicle options, reduce trip times, and provide a robust platform for conducting new missions destined to rewrite textbooks with the

    Aim: To evaluate whether focal liver lesions (FLLs) exhibit a homogeneous appearance on apparent diffusion coefficient (ADC) maps and whether there is inter-section variation in the calculated ADC values of FLLs (inter-section range). Materials and methods: Eighty-eight patients with 128 FLLs (70 benign, 58 malignant) who underwent abdominal magnetic resonance imaging (MRI) including diffusion-weighted (DW)-MRI were included. Two observers evaluated variation of signal intensity of each FLL within each ADC map image (intra-section) and among different ADC map images through the lesion (inter-section). ADC values of each FLL and neighbouring liver parenchyma were measured on all sections. The inter-section range of FLLs was compared with the neighbouring liver parenchyma. Results: Intra-section inhomogeneity was noted in 39.8% (97/244 sections) and 38.9% (95/244) of benign lesions, and 61% (114/187 sections) and 61.5% (115/187) of malignant lesions, by observer 1 and observer 2, respectively. Inter-section inhomogeneity was noted in 25.7% (18/70) and 27.1% (19/70) of benign lesions, and 51.7% (30/58) and 50% (29/58) of malignant lesions, by observer 1 and observer 2, respectively. The inter-section range for both benign (0.28 × 10 −3  mm²/s) and malignant (0.25 × 10 −3  mm²/s) FLLs were significantly greater than that of liver parenchyma surrounding benign (0.16 × 10 −3  mm²/s, p < 0.001) and malignant (0.14 × 10 −3  mm²/s, p = 0.01) FLLs. Conclusion: Due to intra-/inter-section variations in ADC values of benign and malignant FLLs, a single ADC value may not reliably represent the entire lesion

    The technique of the 60 degree supine oblique view is described together with anatomic skeletal studies of this projection. The view is convenient for emergency room radiography and useful in other clinical radiography. The view separates widely the anterior and posterior portions of the vertebrae in a side to side projection. This makes for an elongated but detailed view of the articular processes, pedicles, and intervertebral foramina. In the cadavar specimen and clinically the view is shown to be useful in delineating fracture deformities of the articular process and visualizing constriction of the intervertebral foramen superiorly. Encroachment of the foramen superiorly is likely to compromise the emerging nerve root in this area

    Our aim was to analyze the outcomes of endovascular exclusion of the entire aortic arch (proximal landing in zone 0, distal landing in zone III or beyond, after Ishimaru) in which complete surgical debranching of the supra-aortic vessels (I), endovascular supra-aortic revascularization (chimney, fenestrated, or branched grafts) with partial surgical debranching (II), or total endovascular supra-aortic revascularization (III) was additionally performed. Publications describing endovascular repair of the aortic arch (2000-2016) were systematically searched and reviewed. From a total of 53 relevant studies including 1853 patients, only 1021 patients undergoing 35 different total aortic arch procedures were found eligible for further evaluation and included in group I, II, or III (429, 190, and 402 patients, respectively). Overall early mortality was higher in group I vs groups II and III (P = .001; 1 - β = 95.6%) but exceeded in group III (18.6%) and group II (14.0%) vs group I (8.0%; P = .044; 1 - β = 57.4%) for diseases involving zone 0. Mortality was higher in all subgroups treated for zone 0 disease compared with corresponding subgroups treated for zone I to zone III disease. The incidence of cerebral ischemic events was increased in groups I and II vs group III (7.5% and 11% vs 1.7%; P = .0001) and correlated with early mortality (R 2  = .20; P = .033). The incidence of type II endoleaks and endovascular reintervention was similar between groups and correlated with each other (R 2  = .37; P = .004). Type Ia endoleak occurred more often in groups II and III than in group I (7.1% and 12.1% vs 5.8%; P = .023) and correlated with midterm mortality (R 2  = .53; P = .005). Retrograde type A dissection was low in all groups, whereas aneurysm growth was higher in group III (2.6%, 4.2%, 10.7%; P = .002), correlating with midterm mortality (R 2  = .311; P = .009). Surgical revision slightly correlated with surgical complications (R 2  = .18; P = .044

    defects in the future. Finally, the Gamma test has become a popular metric for reporting TPS Commissioning and QA results. It simplifies complex testing into a numerical index, but noisy data and casual application can make it misleading. A brief review of the issues around the use of the Gamma test will be presented. TPS commissioning and QA: A process orientation and application of control charts (Michael Sharpe) A framework for commissioning a treatment planning system will be presented, focusing on preparations, practical aspects of configuration, priorities, specifications, and establishing performance. The complexity of the modern TPS make modular testing of features inadequate, and modern QA tools can provide “too much information” about the performance of techniques like IMRT and VMAT. We have adopted a process orientation and quality tools, like control charts, for ongoing TPS QA and assessment of patient-specific tests. The trending nature of these tools reveals the overall performance of the TPS system, and quantifies the variations that arise from individual plans, discrete calculations, and experimentation based on discrete measurements. Examples demonstrating application of these tools to TPS QA will be presented. TPS commissioning and QA: Incorporating the entire planning process (Sasa Mutic) The TPS and its features do not perform in isolation. Instead, the features and modules are key components in a complex process that begins with CT Simulation and extends to treatment delivery, along with image guidance and verification. Most importantly, the TPS is used by people working in a multi-disciplinary environment. It is very difficult to predict the outcomes of human interactions with software.

    defects in the future. Finally, the Gamma test has become a popular metric for reporting TPS Commissioning and QA results. It simplifies complex testing into a numerical index, but noisy data and casual application can make it misleading. A brief review of the issues around the use of the Gamma test will be presented. TPS commissioning and QA: A process orientation and application of control charts (Michael Sharpe) A framework for commissioning a treatment planning system will be presented, focusing on preparations, practical aspects of configuration, priorities, specifications, and establishing performance. The complexity of the modern TPS make modular testing of features inadequate, and modern QA tools can provide “too much information” about the performance of techniques like IMRT and VMAT. We have adopted a process orientation and quality tools, like control charts, for ongoing TPS QA and assessment of patient-specific tests. The trending nature of these tools reveals the overall performance of the TPS system, and quantifies the variations that arise from individual plans, discrete calculations, and experimentation based on discrete measurements. Examples demonstrating application of these tools to TPS QA will be presented. TPS commissioning and QA: Incorporating the entire planning process (Sasa Mutic) The TPS and its features do not perform in isolation. Instead, the features and modules are key components in a complex process that begins with CT Simulation and extends to treatment delivery, along with image guidance and verification. Most importantly, the TPS is used by people working in a multi-disciplinary environment. It is very difficult to predict the outcomes of human interactions with software. Therefore, an interdisciplinary approach to training, commissioning and QA will be presented, along with an approach to the physics chart check and end-to-end testing as a tool for TPS QA. The role of standardization and automation in QA will also be discussed

    The site characterization and validation project lasted for five years from 1986 to 1991. It consisted of a number of experiments within the region known as the SCV site. During this period of experimentation a monitoring system was established within the mine for the purpose of measuring the variation of head at a number of locations within and around the site. The system installed was based around a set of equipment known as a Piezomac TM system. In this system there is one central pressure transducer and each borehole interval is connected to it in turn. It can measure up to 55 separate points during each measurement 'cycle'. Monitoring points were either complete boreholes or sections of boreholes isolated by packers. In order to produce reasonable file size, data sets were screened. The results show that the SCV site was always responding to some form of hydrogeological disturbance. Many key tests were performed against changing background trends. This was particularly so of the simulated drift experiment and the large scale crosshole tests. However, some estimates of long term equilibrium heads before and after excavation of the validation drift have been made. Contoured plots of heads before and after show significant reduction of steady state heads as a result of drift excavation. Furthermore contouring the estimated long term drawdowns responding to the simulated drift experiment shows the specific influence of the H zone and the A/B zone. Overall the results of the monitoring show that the mine was a very active hydrogeological environment during the experimentation. Additionally it was often very difficult to clearly identify the causes of such disturbances. (au)

    Studies of terrestrial biotic and environmental dynamics of the last interglacial period, Marine Oxygen Isotope Stage (MIS) 5, provide insight into the effects of long-term climate change on Pleistocene ecosystems. In North America, however, there are relatively few fossil sites that definitively date to MIS 5. Even fewer contain multiple ecosystem components (vertebrates, invertebrates, plants) that have been studied in detail, and none are located at high elevation. Thus, our view of North American ecosystems during MIS 5 is, at best, an incomplete composite view, and alpine ecosystems are entirely undocumented. The Ziegler Reservoir fossil site allows us to begin filling these gaps. Discovered on October 14, 2010 by a construction crew while enlarging a small reservoir near Snowmass Village, Colorado (USA), the site is situated high in the Rocky Mountains at an elevation of ~ 2705 m. Initial excavations exposed a series of stacked fossil ecosystems, including abundant faunal and floral components. Subsequent work revealed an exceptionally diverse biota composed of nearly 6000 large bones of late Pleistocene megafauna, including mastodons, mammoths, ground sloths, horses, camels, deer, bison, black bear, coyotes, and big horn sheep. This collection is complemented by more than 200 bones from at least 40 species of small animals including otters, muskrats, minks, rabbits, beavers, frogs, lizards, snakes, fish, and birds, and more than 20,000 salamander bones. Geomorphic evidence and multiple dating techniques show that the small, ridge-top basin containing the site was formed by a lateral lobe of a valley glacier that filled, and ultimately overtopped, the Snowmass Creek drainage during the Bull Lake glaciation (MIS 6). When the glacier receded, a lake that occupied the basin began to fill slowly with what is hypothesized to be eolian sediment and occasional input from slope failures of the impounding moraine. As sedimentation continued, the lake transformed first

  18. Synchronizing XPath Views

    Pedersen, Dennis; Pedersen, Torben Bach

    2004-01-01

    The increasing availability of XML-based data sources, e.g., for publishing data on the WWW, means that more and more applications (data consumers) rely on accessing and using XML data. Typically, the access is achieved by defining views over the XML data, and accessing data through these views....... However, the XML data sources are often independent of the data consumers and may change their schemas without notification, invalidating the XML views defined by the data consumers. This requires the view definitions to be updated to reflect the new structure of the data sources, a process termed view...... synchronization. XPath is the most commonly used language for retrieving parts of XML documents, and is thus an important cornerstone for XML view definitions. This paper presents techniques for discovering schema changes in XML data sources and synchronizing XPath-based views to reflect these schema changes...

    2009-01-01

    NASA's Mars Exploration Rover Spirit used its navigation camera to take the images combined into this 210-degree view of the rover's surroundings during the 1,861st to 1,863rd Martian days, or sols, of Spirit's surface mission (March 28 to 30, 2009). The center of the scene is toward the south-southwest. East is on the left. West-northwest is on the right. The rover had driven 22.7 meters (74 feet) southwestward on Sol 1861 before beginning to take the frames in this view. The drive brought Spirit past the northwestern corner of Home Plate. In this view, the western edge of Home Plate is on the portion of the horizon farthest to the left. A mound in middle distance near the center of the view is called 'Tsiolkovsky' and is about 40 meters (about 130 feet) from the rover's position. This view is presented as a cylindrical projection with geometric seam correction.

    1984-01-01

    Oblique views of the fingers, using a low kilovolt technique, show a portion of the tendon sheaths which can be regarded as representative of the entire sheath. Because of the varying obliquity of each finger, this proportion differs in the fingers. With increasing age the projected portion of the sheath becomes smaller because it is covered by increasing bone formation in the insertion of the tendon sheat. Normal values have been obtained for adults according to their decades; from these, quite minor degrees of tendon sheat thickening can be determined. In camptodactyly of the fifth finger, which is not uncommon, the tendon sheat may be widened in the absence of a tenosynovitis. (orig.) [de

  1. Hyperbolicity of projective hypersurfaces

    CERN Document Server

    Diverio, Simone

    2016-01-01

    This book presents recent advances on Kobayashi hyperbolicity in complex geometry, especially in connection with projective hypersurfaces. This is a very active field, not least because of the fascinating relations with complex algebraic and arithmetic geometry. Foundational works of Serge Lang and Paul A. Vojta, among others, resulted in precise conjectures regarding the interplay of these research fields (e.g. existence of Zariski dense entire curves should correspond to the (potential) density of rational points). Perhaps one of the conjectures which generated most activity in Kobayashi hyperbolicity theory is the one formed by Kobayashi himself in 1970 which predicts that a very general projective hypersurface of degree large enough does not contain any (non-constant) entire curves. Since the seminal work of Green and Griffiths in 1979, later refined by J.-P. Demailly, J. Noguchi, Y.-T. Siu and others, it became clear that a possible general strategy to attack this problem was to look at particular algebr...

  6. Research on bimodal particle extinction coefficient during Brownian coagulation and condensation for the entire particle size regime

    International Nuclear Information System (INIS)

    Tang Hong; Lin Jianzhong

    2011-01-01

    The extinction coefficient of atmospheric aerosol particles influences the earth’s radiation balance directly or indirectly, and it can be determined by the scattering and absorption characteristics of aerosol particles. The problem of estimating the change of extinction coefficient due to time evolution of bimodal particle size distribution is studied, and two improved methods for calculating the Brownian coagulation coefficient and the condensation growth rate are proposed, respectively. Through the improved method based on Otto kernel, the Brownian coagulation coefficient can be expressed simply in powers of particle volume for the entire particle size regime based on the fitted polynomials of the mean enhancement function. Meanwhile, the improved method based on Fuchs–Sutugin kernel is developed to obtain the condensation growth rate for the entire particle size regime. And then, the change of the overall extinction coefficient of bimodal distributions undergoing Brownian coagulation and condensation can be estimated comprehensively for the entire particle size regime. Simulation experiments indicate that the extinction coefficients obtained with the improved methods coincide fairly well with the true values, which provide a simple, reliable, and general method to estimate the change of extinction coefficient for the entire particle size regime during the bimodal particle dynamic processes.

  16. Hierarchical Linked Views

    Energy Technology Data Exchange (ETDEWEB)

    Erbacher, Robert; Frincke, Deb

    2007-07-02

    Coordinated views have proven critical to the development of effective visualization environments. This results from the fact that a single view or representation of the data cannot show all of the intricacies of a given data set. Additionally, users will often need to correlate more data parameters than can effectively be integrated into a single visual display. Typically, development of multiple-linked views results in an adhoc configuration of views and associated interactions. The hierarchical model we are proposing is geared towards more effective organization of such environments and the views they encompass. At the same time, this model can effectively integrate much of the prior work on interactive and visual frameworks. Additionally, we expand the concept of views to incorporate perceptual views. This is related to the fact that visual displays can have information encoded at various levels of focus. Thus, a global view of the display provides overall trends of the data while focusing in on individual elements provides detailed specifics. By integrating interaction and perception into a single model, we show how one impacts the other. Typically, interaction and perception are considered separately, however, when interaction is being considered at a fundamental level and allowed to direct/modify the visualization directly we must consider them simultaneously and how they impact one another.

  18. Fully automated reconstruction of three-dimensional vascular tree structures from two orthogonal views using computational algorithms and productionrules

    Science.gov (United States)

    Liu, Iching; Sun, Ying

    1992-10-01

    A system for reconstructing 3-D vascular structure from two orthogonally projected images is presented. The formidable problem of matching segments between two views is solved using knowledge of the epipolar constraint and the similarity of segment geometry and connectivity. The knowledge is represented in a rule-based system, which also controls the operation of several computational algorithms for tracking segments in each image, representing 2-D segments with directed graphs, and reconstructing 3-D segments from matching 2-D segment pairs. Uncertain reasoning governs the interaction between segmentation and matching; it also provides a framework for resolving the matching ambiguities in an iterative way. The system was implemented in the C language and the C Language Integrated Production System (CLIPS) expert system shell. Using video images of a tree model, the standard deviation of reconstructed centerlines was estimated to be 0.8 mm (1.7 mm) when the view direction was parallel (perpendicular) to the epipolar plane. Feasibility of clinical use was shown using x-ray angiograms of a human chest phantom. The correspondence of vessel segments between two views was accurate. Computational time for the entire reconstruction process was under 30 s on a workstation. A fully automated system for two-view reconstruction that does not require the a priori knowledge of vascular anatomy is demonstrated.

    Last year saw very good progress at ESO's Paranal Observatory , the site of the Very Large Telescope (VLT). The third and fourth 8.2-m Unit Telescopes, MELIPAL and YEPUN had "First Light" (cf. PR 01/00 and PR 18/00 ), while the first two, ANTU and KUEYEN , were busy collecting first-class data for hundreds of astronomers. Meanwhile, work continued towards the next phase of the VLT project, the combination of the telescopes into the VLT Interferometer. The test instrument, VINCI (cf. PR 22/00 ) is now being installed in the VLTI Laboratory at the centre of the observing platform on the top of Paranal. Below is a new collection of video sequences and photos that illustrate the latest developments at the Paranal Observatory. The were obtained by the EPR Video Team in December 2000. The photos are available in different formats, including "high-resolution" that is suitable for reproduction purposes.

    2000-01-01

    This 3-D perspective view looking north over Death Valley, California, was produced by draping ASTER nighttime thermal infrared data over topographic data from the US Geological Survey. The ASTER data were acquired April 7, 2000 with the multi-spectral thermal infrared channels, and cover an area of 60 by 80 km (37 by 50 miles). Bands 13, 12, and 10 are displayed in red, green and blue respectively. The data have been computer enhanced to exaggerate the color variations that highlight differences in types of surface materials. Salt deposits on the floor of Death Valley appear in shades of yellow, green, purple, and pink, indicating presence of carbonate, sulfate, and chloride minerals. The Panamint Mtns. to the west, and the Black Mtns. to the east, are made up of sedimentary limestones, sandstones, shales, and metamorphic rocks. The bright red areas are dominated by the mineral quartz, such as is found in sandstones; green areas are limestones. In the lower center part of the image is Badwater, the lowest point in North America.Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of International Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, Calif., is the U.S. Science team leader; Moshe Pniel of JPL is the project manager. ASTER is the only high resolution imaging sensor on Terra. The primary goal of the ASTER mission is to obtain high-resolution image data in 14 channels over the entire land surface, as well as black and white stereo images. With revisit time of between 4 and 16 days, ASTER will provide the capability for repeat coverage of changing areas on Earth's surface.The broad spectral coverage and high spectral resolution of ASTER will provide

  4. Extrafoveal Video Extension for an Immersive Viewing Experience.

    Science.gov (United States)

    Turban, Laura; Urban, Fabrice; Guillotel, Philippe

    2016-02-11

    Between the recent popularity of virtual reality (VR) and the development of 3D, immersion has become an integral part of entertainment concepts. Head-mounted Display (HMD) devices are often used to afford users a feeling of immersion in the environment. Another technique is to project additional material surrounding the viewer, as is achieved using cave systems. As a continuation of this technique, it could be interesting to extend surrounding projection to current television or cinema screens. The idea would be to entirely fill the viewer's field of vision, thus providing them with a more complete feeling of being in the scene and part of the story. The appropriate content can be captured using large field of view (FoV) technology, using a rig of cameras for 110 to 360 capture, or created using computergenerated images. The FoV is, however, rather limited in its use for existing (legacy) content, achieving between 36 to 90 degrees () field, depending on the distance from the screen. This paper seeks to improve this FoV limitation by proposing computer vision techniques to extend such legacy content to the peripheral (extrafoveal) vision without changing the original creative intent or damaging the viewer's experience. A new methodology is also proposed for performing user tests in order to evaluate the quality of the experience and confirm that the sense of immersion has been increased. This paper thus presents: i) an algorithm to spatially extend the video based on human vision characteristics, ii) its subjective results compared to state-of-the-art techniques, iii) the protocol required to evaluate the quality of the experience (QoE), and iv) the results of the user tests.

    Research demonstrates that although many mothers initiate pumping for their critically ill children, few women are successful at maintaining milk supply throughout their infants' entire hospital stay. At the Garbose Family Special Delivery Unit (SDU) at the Children's Hospital of Philadelphia, we care for mothers who have critically ill infants born with complex cardiac and congenital anomalies. Human milk is viewed as a medical intervention at our institution. Therefore, nurses on the SDU wanted to ensure best practice in terms of pumping initiation. This article describes a continuous quality improvement project that ensured mothers pumped early and often. Childbirth educators can play a key role in preparing mothers who are anticipating an infant who will require hospitalization immediately post-birth.

    It is well known that gastrectomy with curative intent is the best way to improve outcomes of patients with remnant gastric cancer. Recently,several investigators reported their experiences with laparoscopic gastrectomy of remnant gastric cancer. We report the case of an 83-year-old female patient who was diagnosed with remnant gastric cancer with obstruction. She underwent an entirely laparoscopic distal gastrectomy with colectomy because of direct invasion of the transverse colon. The opera...

    Different levels of dried Jerusalem artichoke were fed to entire male pigs 1 week before slaughter. The objective was to investigate the effect on skatole level in the hindgut and in adipose tissue, as well as the effect on microflora and short-chain fatty acids (SCFA) in the hindgut. Five experimental groups (n = 11) were given different dietary treatments 7 days before slaughtering: negative control (basal diet), positive control (basal diet + 9% chicory-inulin), basal diet + 4.1% Jerusalem artichoke, basal diet + 8.1% Jerusalem artichoke and basal diet + 12.2% Jerusalem artichoke. Samples from colon, rectum, faeces and adipose tissue were collected. Effect of dietary treatment on skatole, indole and androstenone levels in adipose tissue and on skatole, indole, pH, dry matter (DM), microbiota and SCFA in the hindgut was evaluated. Feeding increasing levels of Jerusalem artichoke to entire male pigs reduced skatole in digesta from colon and in faeces (linear, P Jerusalem artichoke decreased DM content in colon and faeces and pH in colon (linear, P Jerusalem artichoke resulted in a reduced level of Clostridium perfringens in both colon and rectum (linear, P Jerusalem artichoke to diets for entire male pigs 1 week before slaughter resulted in a dose-dependent decrease in skatole levels in the hindgut and adipose tissue. The reduced skatole levels might be related to the decrease in C. perfringens and the increase in SCFA with subsequent reduction in pH.

    The study aimed to characterize the entire corneal topography and tomography for the detection of sub-clinical keratoconus (KC) with a Zernike application method. Normal subjects (n = 147; 147 eyes), sub-clinical KC patients (n = 77; 77 eyes), and KC patients (n = 139; 139 eyes) were imaged with the Pentacam HR system. The entire corneal data of pachymetry and elevation of both the anterior and posterior surfaces were exported from the Pentacam HR software. Zernike polynomials fitting was used to quantify the 3D distribution of the corneal thickness and surface elevation. The root mean square (RMS) values for each order and the total high-order irregularity were calculated. Multimeric discriminant functions combined with individual indices were built using linear step discriminant analysis. Receiver operating characteristic curves determined the diagnostic accuracy (area under the curve, AUC). The 3rd-order RMS of the posterior surface (AUC: 0.928) obtained the highest discriminating capability in sub-clinical KC eyes. The multimeric function, which consisted of the Zernike fitting indices of corneal posterior elevation, showed the highest discriminant ability (AUC: 0.951). Indices generated from the elevation of posterior surface and thickness measurements over the entire cornea using the Zernike method based on the Pentacam HR system were able to identify very early KC.

    2003-11-01

    With the rise in obesity in America, the search for potential causes for this epidemic has begun to include a focus on environmental factors. Television (TV) viewing is one such factor, partially due to its potential as a stimulus for eating. The current study investigated the relationship between food intake and self-reported TV viewing in an effort to identify the impact of TV viewing on specific eating behaviors. Seventy-four overweight women seeking obesity treatment completed questionnaires assessing dietary habits and TV viewing behaviors. Results suggest that snacking, but not necessarily eating meals, while watching TV is associated with increased overall caloric intake and calories from fat. Therefore, interventions targeting stimulus control techniques to reduce snacking behavior may have an impact on overall caloric intake.

    In an era when big data are becoming the norm, there is less concern with the quantity but more with the quality and completeness of the data. In many disciplines, data are collected from heterogeneous sources, resulting in multi-view or multi-modal datasets. The missing data problem has been challenging to address in multi-view data analysis. Especially, when certain samples miss an entire view of data, it creates the missing view problem. Classic multiple imputations or matrix completion methods are hardly effective here when no information can be based on in the specific view to impute data for such samples. The commonly-used simple method of removing samples with a missing view can dramatically reduce sample size, thus diminishing the statistical power of a subsequent analysis. In this paper, we propose a novel approach for view imputation via generative adversarial networks (GANs), which we name by VIGAN. This approach first treats each view as a separate domain and identifies domain-to-domain mappings via a GAN using randomly-sampled data from each view, and then employs a multi-modal denoising autoencoder (DAE) to reconstruct the missing view from the GAN outputs based on paired data across the views. Then, by optimizing the GAN and DAE jointly, our model enables the knowledge integration for domain mappings and view correspondences to effectively recover the missing view. Empirical results on benchmark datasets validate the VIGAN approach by comparing against the state of the art. The evaluation of VIGAN in a genetic study of substance use disorders further proves the effectiveness and usability of this approach in life science.

  7. Collective Attitudes and the Anthropocentric View

    Directory of Open Access Journals (Sweden)

    Gallotti Mattia

    2016-03-01

    Full Text Available The anthropocentric view holds that the social world is a projection of mental states and attitudes onto the real world. However, there is more to a society of individuals than their psychological make up. In The Ant Trap, Epstein hints at the possibility that collective intentionality can, and should, be discarded as a pillar of social ontology. In this commentary I argue that this claim is motivated by an outdated view of the nature and structure of collective attitudes. If we aim at a good theory of social ontology, we need a good theory of collective intentionality.

    PurposeThis study was designed to investigate the safety and efficacy of endovascular intervention for the treatment of primary entire-inferior vena cava (IVC) occlusion.MethodsEndovascular interventions were performed in six patients for the treatment of primary entire-IVC occlusion. IVC and hepatic venography were performed via the jugular and femoral veins. Balloon angioplasty was used to revascularize the hepatic vein and IVC and a stent was placed in the IVC to maintain patency. Postoperative color Doppler ultrasonography was performed at 1, 3, 6, and 12 months, and then annually, to monitor the patency of the hepatic vein and IVC.ResultsThe IVC and one or two hepatic veins were successfully revascularized in five patients. Revascularization was successful in the right and left hepatic veins in one patient; however, IVC patency could not be established in this patient. Eleven Z-type, self-expanding stents were placed into the IVCs of five patients (three stents in two patients, two stents in two patients, and one stent in one patient). There were no instances of postoperative bleeding or mortality. Follow-up was conducted for 18–90 months (42.8 ± 26.5 months). None of the five patients suffered restenosis of the IVC or hepatic veins. However, there was one of the six cases of right hepatic vein restenosis at 18 months postprocedure that was revascularized after a second balloon dilatation.ConclusionsEndovascular intervention is safe and efficacious for the treatment of primary entire-IVC occlusion

    Organizations that rely on projects to implement their products must find effective mechanisms for propagating lessons learned on one project throughout the organization. A broad view of what constitutes a project's 'legacy' is presented that includes not just the design products and leftover parts, but new processes, relationships, technology, skills, planning data, and performance metrics. Based on research evaluating knowledge reuse in innovative contexts, this paper presents an approach to project legacy management that focuses on collecting and using legacy knowledge to promote organizational learning and effective reuse, while addressing factors of post-project responsibility, information obsolescence, and the importance of ancillary contextual information. .

    Cavalli-Sforza, L. [Stanford Univ., CA (United States)

    1994-12-31

    The Human Genome Diversity Project (HGD Project) is an international anthropology project that seeks to study the genetic richness of the entire human species. This kind of genetic information can add a unique thread to the tapestry knowledge of humanity. Culture, environment, history, and other factors are often more important, but humanity`s genetic heritage, when analyzed with recent technology, brings another type of evidence for understanding species` past and present. The Project will deepen the understanding of this genetic richness and show both humanity`s diversity and its deep and underlying unity. The HGD Project is still largely in its planning stages, seeking the best ways to reach its goals. The continuing discussions of the Project, throughout the world, should improve the plans for the Project and their implementation. The Project is as global as humanity itself; its implementation will require the kinds of partnerships among different nations and cultures that make the involvement of UNESCO and other international organizations particularly appropriate. The author will briefly discuss the Project`s history, describe the Project, set out the core principles of the Project, and demonstrate how the Project will help combat the scourge of racism.

    2006-05-01

    An immersive viewing engine providing basic telepresence functionality for a variety of application types is presented. Augmented reality, teleoperation and virtual reality applications all benefit from the use of head mounted display devices that present imagery appropriate to the user's head orientation at full frame rates. Our primary application is the viewing of remote environments, as with a camera equipped teleoperated vehicle. The conventional approach where imagery from a narrow field camera onboard the vehicle is presented to the user on a small rectangular screen is contrasted with an immersive viewing system where a cylindrical or spherical format image is received from a panoramic camera on the vehicle, resampled in response to sensed user head orientation and presented via wide field eyewear display, approaching 180 degrees of horizontal field. Of primary interest is the user's enhanced ability to perceive and understand image content, even when image resolution parameters are poor, due to the innate visual integration and 3-D model generation capabilities of the human visual system. A mathematical model for tracking user head position and resampling the panoramic image to attain distortion free viewing of the region appropriate to the user's current head pose is presented and consideration is given to providing the user with stereo viewing generated from depth map information derived using stereo from motion algorithms.

  15. Is it necessary to use the entire root as a donor when transferring contralateral C7 nerve to repair median nerve?

    2018-01-01

    If a partial contralateral C 7 nerve is transferred to a recipient injured nerve, results are not satisfactory. However, if an entire contralateral C 7 nerve is used to repair two nerves, both recipient nerves show good recovery. These findings seem contradictory, as the above two methods use the same donor nerve, only the cutting method of the contralateral C 7 nerve is different. To verify whether this can actually result in different repair effects, we divided rats with right total brachial plexus injury into three groups. In the entire root group, the entire contralateral C 7 root was transected and transferred to the median nerve of the affected limb. In the posterior division group, only the posterior division of the contralateral C 7 root was transected and transferred to the median nerve. In the entire root + posterior division group, the entire contralateral C 7 root was transected but only the posterior division was transferred to the median nerve. After neurectomy, the median nerve was repaired on the affected side in the three groups. At 8, 12, and 16 weeks postoperatively, electrophysiological examination showed that maximum amplitude, latency, muscle tetanic contraction force, and muscle fiber cross-sectional area of the flexor digitorum superficialis muscle were significantly better in the entire root and entire root + posterior division groups than in the posterior division group. No significant difference was found between the entire root and entire root + posterior division groups. Counts of myelinated axons in the median nerve were greater in the entire root group than in the entire root + posterior division group, which were greater than the posterior division group. We conclude that for the same recipient nerve, harvesting of the entire contralateral C 7 root achieved significantly better recovery than partial harvesting, even if only part of the entire root was used for transfer. This result indicates that the entire root should be used as a

    In every outstanding construction project, there is definitely have an effective construction management. Construction management allows a construction project to be implemented according to plan. Every construction project must have a progress development works that is usually created by the site engineer. Documenting the progress of works is one of the requirements in construction management. In a progress report it is necessarily have a visual image as an evidence. The conventional method used for photographing on the construction site is by using common digital camera which is has few setback comparing to Micro Unmanned Aerial Vehicles (UAV). Besides, site engineer always have a current issues involving limitation of monitoring on high reach point and entire view of the construction site. The purpose of this paper is to provide a concise review of Micro UAV technology in monitoring the progress on construction site through visualization approach. The aims of this study are to replace the conventional method of photographing on construction site using Micro UAV which can portray the whole view of the building, especially on high reach point and allows to produce better images, videos and 3D model and also facilitating site engineer to monitor works in progress. The Micro UAV was flown around the building construction according to the Ground Control Points (GCPs) to capture images and record videos. The images taken from Micro UAV have been processed generate 3D model and were analysed to visualize the building construction as well as monitoring the construction progress work and provides immediate reliable data for project estimation. It has been proven that by using Micro UAV, a better images and videos can give a better overview of the construction site and monitor any defects on high reach point building structures. Not to be forgotten, with Micro UAV the construction site progress is more efficiently tracked and kept on the schedule.

    Full Text Available The extension of state activities currently raises the need to fund specific public projects in the area of the infrastructure, ecology, or the entire expenditure programs in the field of education, health and social care and culture. Into the accounts methodology of the national and autonomy administration were introduced the transfers which represent prevalent expenses, capital expenditures, grants, subsidies and contributions. From an accounting perspective views there is an important fact from which the transfer passes, respectively whether the transfer is provided by the founder, the transfer by another entity within the public administration, or the transfer goes from an entity outside of the public administration. Watching transfers is important for the subsequent preparation of consolidated financial statements and summary financial statements of the public administration.

    This paper reports a multiple-scale hierarchically structured superhydrophobic surface that is composed of inclined-wall regular micro-pillar arrays covered entirely with an alumina nanowire forest (ANF) to improve the surface wettability. The multiple-scaled structures were fabricated stably using a simple batch process based on an anisotropic chemical silicon etching process and a subsequent time-controlled anodic aluminum oxide technique. The surface wetting properties of the mono-roughened surfaces with inclined-wall micro-pillar arrays, which are normally in the Wenzel wetting regime, could be transitioned perfectly to the slippery Cassie mode and enhanced greatly in the Wenzel regime in cases of a high- and low-density of the micro-pillars, respectively, by easily amplifying the intrinsic contact angle through the entire coverage of the ANF on the micro-roughened surfaces. The wettability of the proposed multiple-scaled surfaces could also be predicted using analytic surface models and the experimental results agreed greatly with the wetting trends estimated theoretically due to the geometrical regularity of the base micro-structures

A total of 8,000 eggs was collected every 5 wk, from 30 to 81 wk of hen age (10 samplings of 400 eggs/house), in 2 identical poultry houses equipped with enriched cages. For the statistical analysis, ANOVA, Bivariate Correlation, Principal Component Analysis (PCA), and Hierarchical Cluster Analysis were used. An increase of egg weight, length, and eggshell lightness (L*) associated with a reduction of eggshell percentage, breaking strength, and redness (a*) was observed as the hen aged (P 10% of eggshell breaking strength and a*. According to the PCA, the highest changes during the laying cycle are related to egg physical parameters (32%) and to eggshell breaking strength, percentage, and thickness (26%). The egg physical parameters appeared to be strongly correlated to each other, whereas a slight correlation between eggshell breaking strength and color attributes were evidenced (-0.231 and 0.289, respectively, for L* and a*; P quality attributes throughout the entire laying hen cycle.

    Pseudohypoparathyoridism type Ib (PHP-Ib) typically defines the presence of end-organ resistance to parathyroid hormone in the absence of Albright's hereditary osteodystrophy. Patients affected by this disorder present with imprinting defects in the complex GNAS locus. Microdeletions within STX16 or GNAS have been identified in familial cases with PHP-Ib, but the molecular cause of the GNAS imprinting defects in sporadic PHP-Ib cases remains poorly defined. We now report a case with sporadic PHP-Ib for whom a SNPlex analysis revealed loss of the maternal GNAS allele. Further analysis of the entire genome with a 100K SNP chip identified a paternal uniparental isodisomy affecting the entire chromosome 20 without evidence for another chromosomal abnormality. Our findings explain the observed GNAS methylation changes and the patient's hormone resistance, and furthermore suggest that chromosome 20 harbors, besides GNAS, no additional imprinted region that contributes to the clinical and laboratory phenotype.

    Muscle shear elastic modulus is linearly related to muscle torque during low-level contractions (torque over the entire range of isometric contraction and (ii) the influence of the size of the region of interest (ROI) used to average the shear modulus value. Ten healthy males performed two incremental isometric little finger abductions. The joint torque produced by Abductor Digiti Minimi was considered as an index of muscle torque and elastic modulus. A high coefficient of determination (R(2)) (range: 0.86-0.98) indicated that the relationship between elastic modulus and torque can be accurately modeled by a linear regression over the entire range (0% to 100% of MVC). The changes in shear elastic modulus as a function of torque were highly repeatable. Lower R(2) values (0.89±0.13 for 1/16 of ROI) and significantly increased absolute errors were observed when the shear elastic modulus was averaged over smaller ROI, half, 1/4 and 1/16 of the full ROI) than the full ROI (mean size: 1.18±0.24cm(2)). It suggests that the ROI should be as large as possible for accurate measurement of muscle shear modulus. Copyright © 2015 Elsevier Ltd. All rights reserved.

  2. Dysplastic Ichthyosis Uteri-like changes of the entire endometrium associated with a squamous cell carcinoma of the uterine cervix

    Full Text Available Abstract Ichthyosis uteri is an exceedingly rare condition in which the entire surface of the endometrium is replaced by stratified squamous epithelium. Originally described as an endometrial response to iatrogenically-introduced caustic substances, similar changes have since been described in association with a variety of inflammatory conditions of the endometrium. We describe herein a heretofore undescribed example of a moderately differentiated squamous cell carcinoma of the uterine cervix associated with extensive ichthyosis uteri-like changes of the entire adjacent endometrium. Additionally, the squamous epithelium of the latter also showed multifocal changes diagnostic of a low-grade squamous intraepithelial lesion. The potential genesis of this composite of findings is discussed, as is the neoplastic potential of ichthyosis uteri. It is concluded that a squamous cell carcinoma of the cervix extended proximally into the endometrium, and that there was a colonization of a pre-existing ichthyosis uteri by associated human papillomavirus. The possibility of significant cervical pathology should be considered when plaques of squamous epithelium with low grade dysplastic changes are identified in an endometrial biopsy or curettage.

  3. The diagnostic value of the 'skyline' view for radiographic examination of the equine navicular bone

    Zweers, A.D.; Dik, K.J.

    1988-01-01

    The radiographic diagnostic value of Rose's palmaroproximal-dorsodistal ('skyline') projection and Oxspring's dorsopalmar projection of the equine navicular bone were compared, by examining radiographs of 102 navicular bones originating from 66 randomly selected horses with clinical evidence of lameness located in the navicular area. In 27 navicular bones essential information was obtained from the skyline view, 15 independently of Oxspring's projection and 12 in addition to this view. For 11 navicular studies the D.P. projection was the most important diagnostic view. In the other 64 navicular bones information obtained from both views was of equal diagnostic value. Based on these results it is suggested that the skyline projection be utilized as an additional view, especially if there is a significant discrepancy between the clinical and radiographic findings based on lateromedial and Oxspring projections, and if ill-defined lesions of unknown significance are visible on the Oxspring projection [nl

    An object in a nuclear power plant is viewed through a radiation-proof shield by means of an entrance lens, optic fibre bundle and exit lens. The optic fibre bundle being heated to ensure thermostabilization of its light conducting properties in the presence of ionising radiation. Heating is by an electric heating coil. Alternatively, heating may be by argon itself heated by an electric heating element, a coating of resistive heating material, or absorption of neutrons in the material of the fibres or a coating therefor. Viewing may be on a CRT screen. (author)

  5. 2020 Vision Project Summary

    Gordon, K.W.; Scott, K.P.

    2000-11-01

    Since the 2020 Vision project began in 1996, students from participating schools have completed and submitted a variety of scenarios describing potential world and regional conditions in the year 2020 and their possible effect on US national security. This report summarizes the students' views and describes trends observed over the course of the 2020 Vision project's five years. It also highlights the main organizational features of the project. An analysis of thematic trends among the scenarios showed interesting shifts in students' thinking, particularly in their views of computer technology, US relations with China, and globalization. In 1996, most students perceived computer technology as highly beneficial to society, but as the year 2000 approached, this technology was viewed with fear and suspicion, even personified as a malicious, uncontrollable being. Yet, after New Year's passed with little disruption, students generally again perceived computer technology as beneficial. Also in 1996, students tended to see US relations with China as potentially positive, with economic interaction proving favorable to both countries. By 2000, this view had transformed into a perception of China emerging as the US' main rival and ''enemy'' in the global geopolitical realm. Regarding globalization, students in the first two years of the project tended to perceive world events as dependent on US action. However, by the end of the project, they saw the US as having little control over world events and therefore, we Americans would need to cooperate and compromise with other nations in order to maintain our own well-being.

  13. Hydro-electric power project on the Toulnustouc River

    International Nuclear Information System (INIS)

    Rochon, Y.; Morneau, J.; Lefebvre, G.

    2001-01-01

    Hydro-Quebec has proposed the development of a hydro-electric power project on the Toulnustouc River, located between Saint-Anne Lake and Manic Reservoir. The work would involve the construction of a power generation plant of 526 MW, construction of a 77 m dam on the Toulnustouc River, 14 km downstream from the existing Lac-Saint-Anne dam, the creation of a new water expanse covering 22 square kilometers, the construction of an embankment, the strengthening of the existing Saint-Anne embankment, digging a 9.8 km gallery, and the construction of a flood spillway. This work would have consequences for three different sectors of the river: between the existing and the proposed dam, between the dam and the projected power plant, and between the power plant and the limit of the influence of the reservoir Manic-2. Hydro-Quebec would like the work to begin in July 2001, with the aim of having the plant in operation in 2005. The overall cost of the project is estimated at 600 million dollars. It is expected that the economic benefits for the region would be in the 211 million dollar range. An environmental assessment of the entire project was performed by Quebec Ministere de l'Environnement. The authors determined that the project was recognized as justified by the Ministere des Ressources Naturelles (Natural Resources Ministry) and concluded that the project was acceptable from an environmental point of view as long as six conditions were met. They touched on the construction of a flood spillway capable of evacuating 19 cubic meters per second at any time during the year, that water be evacuated downstream following a pre-determined debit that varies according to the time of year, monitoring of the brook trout population and its habitat, and environmental monitoring. 46 refs., 7 tabs., 2 figs., 1 annex

    2013-01-01

    The topic of this book is known as dynamic scheduling, and is used to refer to three dimensions of project management and scheduling: the construction of a baseline schedule and the analysis of a project schedule's risk as preparation of the project control phase during project progress. This dynamic scheduling point of view implicitly assumes that the usability of a project's baseline schedule is rather limited and only acts as a point of reference in the project life cycle.

    Full Text Available For treatment of a sinonasal inverted papilloma (IP, it is essential to have a definite diagnosis, to identify its origin by computed tomography (CT and magnetic resonance imaging (MRI, and to select the appropriate surgical approach based on the staging system proposed by Krouse. Recently, a new surgical approach named endoscopic modified medial maxillectomy (EMMM was proposed. This approach can preserve the inferior turbinate and nasolacrimal duct. We successfully treated sinonasal IP with EMMM in a 71-year-old female patient. In this patient, the sinonasal IP originated from the entire circumference of the maxillary sinus. EMMM is not a difficult procedure and provides good visibility of the operative field. Lacrimation and empty nose syndrome do not occur postoperatively as the nasolacrimal duct and inferior turbinate are preserved. EMMM is considered to be a very favorable approach for treatment of sinonasal IP.

    Fournier's gangrene, a rare polymicrobial infection that affects the genitals and perineum, can present as an insidious onset to a rapid and fulminant course. Early recognition, diagnosis, initiation of broad-spectrum antibiotics and prompt surgical treatment remain the foundation of management. If treatment is not initiated aggressively, the patient will likely rapidly deteriorate, leading to organ failure and death. We present the case of a 58-year-old diabetic female presenting febrile, hypoxic, with severe respiratory distress and evidence of septic shock, found to have necrotizing fasciitis of the entire right hemi-pelvis. Despite rapid recognition, IV antibiotics and operative management, the patient went to the intensive-care unit on multiple pressors and died 24 h later.

    In its simplest form, X ray imaging is the collection of attenuation shadows that are projected from an ideal X ray point source on to an image receptor. This simple form is true for all X ray imaging modalities, including complex ones that involve source and receptor movement, such as computed tomography (CT). This simplified view, however, is made vastly more complex by the non-ideal point source, by the consequences of projecting a 3-D object on to a 2-D detector and by the presence of scattered radiation, generated within the patient, which will degrade any image that is captured.

  7. The Gabcikovo-Nagymaros Project

    International Nuclear Information System (INIS)

    Lejon, E.

    1996-01-01

    In this chapter author deals with the different reasons which lead to the conclusion of the treaty on the Gabcikovo-Nagymaros Project (GNP) in 1977. The project reflected the necessity of complex solutions for an entire group of inevitable problems. It was necessary: to stop the erosion of the riverbed in this section of the Danube; to begin realizing effective anti-flood measures, taking into consideration the problems caused by suffusion, the flow velocity increase, and the riverbed erosion; to halt the decrease of the ground water level resulting from the cutoff of river side arms and meandering, from riverbed deepening, etc.; to ensure the hydrogeologic conditions and to receive the hydrologic dynamic of the upper soil layers, particularly with respect to future contamination of the ground water; to stabilize the riverbed and stream characteristics in order to eliminate the difficult and dangerous navigation conditions. Hydraulic characteristics of the GNP system as well as technical data of turbines and generators of the Gabcikovo part are described. Developing of the diplomatic war taking place between Hungary and Czechoslovakia and the present Slovakia is presented. Water level fluctuation in the Danube and ground water level fluctuation are published. The GNP had a positive effect from the energy point of view. The Gabcikovo power plant is able to annually produce some 3,100 mil kWh. During the period of 50 years, the production volumes should exceed 155 billion kWh, in a total value of 323.5 billion Slovak crowns (Sk) at the realistic price of 1.50 Sk per kWh. It would be necessary to annually burn some 4,280.000 tons of brown coal in the Novaky thermal power plant in order to produce the same volume of electricity. This would result in the annual waste production of 1,250.000 tons of ash, which accumulates to a volume of 62 million tons of ash when considered over a 50-year-period. The burning of the 5.38 million tons of coal represents an annual

    Full Text Available Nowadays, development of agroforestry has been focused on the people living near forest. Positive views from community may have a good impact on agroforestry development program. This research aims to study the views of the forest outskrit community on the agroforestry development program in Dulamayo Barat village, Telaga Sub District, Gorontalo Regency, Gorontalo Province. The study used survey approach and focus group discussion (FGD method. Respondents were all the members of agroforestry farmer group. The entire population were taken for interview (10 respondents while FGD was attended by 26 participants. Data were analyzed descriptively. The result showed that 100% of the respondents want the program to be sustainable, although from the socio economic point of view the impact has not contributed significantly. From the respondents views of its benefit, 50% believe that the program is for critical land rehabilitation, 30% have a view for the improvement of environmental service, 10% view to increase community economy, and 10% view that the program is to eliminate erosion. These indicate that the community is concerned with agroforestry development, therefore, continuous facilitation is needed. Furthermore, the community expects to be actively involved in the agroforestry development program.

    The main goal of the chapter is the presentation of the application project portfolio management approach to support development of e-Municipality and public administration information systems. The models of how people publish and utilize information on the web have been transformed continually. Instead of simply viewing on static web pages, users publish their own content through blogs and photo- and video-sharing slides. Analysed in this chapter, ICT (Information Communication Technology) projects for municipalities cover the mixture of the static web pages, e-Government information systems, and Wikis. So, for the management of the ICT projects' mixtures the portfolio project management approach is proposed.

    Well defined biomacromolecular patterns such as binding sites, catalytic sites, specific protein or nucleic acid sequences, etc. precisely modulate many important biological phenomena. We introduce PatternQuery, a web-based application designed for detection and fast extraction of such patterns. The application uses a unique query language with Python-like syntax to define the patterns that will be extracted from datasets provided by the user, or from the entire Protein Data Bank (PDB). Moreover, the database-wide search can be restricted using a variety of criteria, such as PDB ID, resolution, and organism of origin, to provide only relevant data. The extraction generally takes a few seconds for several hundreds of entries, up to approximately one hour for the whole PDB. The detected patterns are made available for download to enable further processing, as well as presented in a clear tabular and graphical form directly in the browser. The unique design of the language and the provided service could pave the way towards novel PDB-wide analyses, which were either difficult or unfeasible in the past. The application is available free of charge at http://ncbr.muni.cz/PatternQuery. © The Author(s) 2015. Published by Oxford University Press on behalf of Nucleic Acids Research.

    2012-01-01

    NASA is developing the Space Launch System -- an advanced heavy-lift launch vehicle that will provide an entirely new capability for human exploration beyond Earth's orbit. The Space Launch System will provide a safe, affordable and sustainable means of reaching beyond our current limits and opening up new discoveries from the unique vantage point of space. The first developmental flight, or mission, is targeted for the end of 2017. The Space Launch System, or SLS, will be designed to carry the Orion Multi-Purpose Crew Vehicle, as well as important cargo, equipment and science experiments to Earth's orbit and destinations beyond. Additionally, the SLS will serve as a backup for commercial and international partner transportation services to the International Space Station. The SLS rocket will incorporate technological investments from the Space Shuttle Program and the Constellation Program in order to take advantage of proven hardware and cutting-edge tooling and manufacturing technology that will significantly reduce development and operations costs. The rocket will use a liquid hydrogen and liquid oxygen propulsion system, which will include the RS-25D/E from the Space Shuttle Program for the core stage and the J-2X engine for the upper stage. SLS will also use solid rocket boosters for the initial development flights, while follow-on boosters will be competed based on performance requirements and affordability considerations.

    Natacha Salomé LIMA

    2015-10-01

    Full Text Available What would happen if man could store and recovered all its memories at will? The entire history of you is an episode of the British television drama series which presents a futuristic scenario of a very old situation: jealousy. Human passions disturb our soul, trouble our reflections, and pushes us to action. Memory will be a privileged object for our analysis; not organic memory, but significant memory: this means the trace of memories that perform our body. We will try to analyze the possibilities of our actions against the technological dangers and “progresses”. The scope of biopolitics presented by Michel Foucault in the 70venties could be taken up by the contemporary idea of the current decline of love, desire and sexuality. We will visit some of the Freudian early works to think how memory and the possibilities of remembrance are a singular construction of human being. This significant memory is capable of knotting remembrance, fantasy and desire. But memory could also become perpetual when it is object of manipulation producing devastating effects on human´s subjectivity.

    The new building called ''Grande Galerie de l'Evolution'' of the national Museum of natural History, in Paris-France, is the first museum in the world exclusively devoted to biological evolution. The Museum is divided in 3 parts (named ''Acts''): The aim of Act 1 is to sensibilize the visitor to the results of 4 billions years of biological evolution. This act shows some examples of biological diversity through few terrestrial and marine environments (deserts, tropical forests, polar habitats, abyssal zones ...). Act 2 is the principal part of the Museum explaining the main processes of evolution. This part shows also the story of life from the first living cells to man. Act 3, the last part offers to visitors a vision of the interactions between man and nature, and of their consequences along millions of years. A special Gallery is entirely devoted to vanished and threatened species, as a nefast consequence of human interaction on biological diversity particularly since the beginning of this century.

    Commercial LWR fuel will be limited to a maximum of U-235 content of 5% since the front end of the fuel cycle is licensed and prepared for that maximal enrichment. BWR- and PWR-reloads can be designed achieving batch average burn up over 60 GWd/tHM. In Germany the batch average burn up will presumably increase to this level, since the reload market is requesting further reductions in the fuel cycle inventories. However, it must be noted that the envisaged benefit can only be assured if the entire fuel cycle is optimized. Not all steps in the fuel cycle will bring a positive contribution bu the balance of all individual contributions must realize the envisaged integral benefit. In order to increase the burn up of the nuclear fuel beneficially further R and D both in the front end as well as in the back end of the fuel cycle is needed. An underestimation of the front end/back end interfaces may consume all benefits gained from isolated front optimizations. Back end R and D must be at once concentrated to avoid conservative enveloping licensing for the subsequent steps in the back end of the fuel cycle. Increasing burn up in the front end means making more and more use of the structural materials reserves

    The objective of this study was to explore the volumetric alterations of dural sinuses in patients with idiopathic intracranial hypertension (IIH). Standardized cranial magnetic resonance imaging (MRI) was used in 17 patients prior to and following treatment of IIH and in seven controls. Magnetic resonance venographies (MRV) were employed for (a) judgement of circumscript dural sinus stenoses and (b) computation of sinus volumes. Cross-sectional areas (CSA) of the superior sagittal sinuses (SSS) were measured on T2-weighted images. Results of the initial MRIs were compared to those on follow-up MRIs and to results of controls. Stenoses of the transverse sinuses (TS) resulting in cranial venous outflow obstruction (CVOO) were present in 15/17 (88%) patients, normalizing in 7/15 cases (47%) after treatment of IIH. CVOO was not detected in the control group. Segmentation of MRV revealed decreased dural sinus volumes in patients with IIH as compared to controls (P = 0.018). Sinus volumes increased significantly with normalization of intracranial pressure independent from disappearing of TS stenoses (P = 0.007). The CSA of the SSS were normal on the initial MRIs of patients with IIH and increased on follow-up after treatment (P < 0.001). However, volumetries displayed overlap in patients and controls. Patients with IIH not only exhibit bilateral stenoses of the TS as has been reported, but volume changes of their entire dural sinus system also occur. The potential etiopathological and diagnostic roles of these changes are discussed. (orig.)

    The purpose of this study is to establish a management process for a power plant to positively find out actual and/or potential problems that may possibility cause a serious human factor event, and to take effective measures. Firstly, detail steps for error management process utilizing human factor event data has been examined through an application at a plant. Secondly, basic steps for evaluating the degree of execution, enhancement and usefulness of each human performance activity and for identifying unsafe acts and uneasy human performance states were established based on literature searching and our experiences on plant evaluation. Finally, an entire picture of error management process was proposed by unifying the steps studied above. In addition, as stages for introducing and establishing the above proposed error management process into a power plant, a basic idea of supplementing an insufficient part of the process with a phased approach after comparing the above proposed management process and the existing human performance activities at the plant was introduced.

  2. Mechanism of the entire overdischarge process and overdischarge-induced internal short circuit in lithium-ion batteries.

    Lithium-ion batteries connected in series are prone to be overdischarged. Overdischarge results in various side effects, such as capacity degradation and internal short circuit (ISCr). However, most of previous research on the overdischarge of a cell was terminated when the cell voltage dropped to 0 V, leaving the further impacts of overdischarge unclear. This paper investigates the entire overdischarge process of large-format lithium-ion batteries by discharging the cell to -100% state of charge (SOC). A significant voltage platform is observed at approximately -12% SOC, and ISCr is detected after the cell is overdischarged when passing the platform. The scanning electron microscopy (SEM) and X-ray diffraction (XRD) results indicate that the overdischarge-induced ISCr is caused by Cu deposition on electrodes, suggesting possible Cu collector dissolution at the voltage platform near -12% SOC. A prognostic/mechanistic model considering ISCr is used to evaluate the resistance of ISCr (RISCr), the value of which decreases sharply at the beginning of ISCr formation. Inducing the ISCr by overdischarge is effective and well controlled without any mechanical deformation or the use of a foreign substance.

    Castor has tremendous potential as a feedstock for biodiesel production. The oil content and fatty acid composition in castor seed are important factors determining the price for production and affecting the key fuel properties of biodiesel. There are 1033 available castor accessions collected or donated from 48 countries worldwide in the USDA germplasm collection. The entire castor collection was screened for oil content and fatty acid composition by nuclear magnetic resonance (NMR) and gas chromatography (GC), respectively. Castor seeds on the average contain 48.2% oil with significant variability ranging from 37.2 to 60.6%. Methyl esters were prepared from castor seed by alkaline transmethylation. GC analysis of methyl esters confirmed that castor oil was composed primarily of eight fatty acids: 1.48% palmitic (C16:0), 1.58% stearic (C18:0), 4.41% oleic (C18:1), 6.42% linoleic (C18:2), 0.68% linolenic (C18:3), 0.45% gadoleic (C20:1), 84.51% ricinoleic (C18:1-1OH), and 0.47% dihydroxystearic (C18:0-2OH) acids. Significant variability in fatty acid composition was detected among castor accessions. Ricinoleic acid (RA) was positively correlated with dihydroxystearic acid (DHSA) but highly negatively correlated with the five other fatty acids except linolenic acid. The results for oil content and fatty acid composition obtained from this study will be useful for end-users to explore castor germplasm for biodiesel production.

    We investigated whether conventional tandem-source dwelling to cover the entire uterus, classically regarded as the target volume, is necessary in modem intracavitary radiotherapy (ICRT) for cervical cancer. The study included 95 cervical squamous cell carcinoma patients treated by high-dose-rate ICRT (point A dose was 6.0 Gy, with three to five insertions per patient) after external beam radiotherapy (EBRT), with central pelvic doses of 12-50 Gy. The tandem-source dwell length was adjusted to the target volume specified by magnetic resonance (MR) imaging. A tandem applicator was inserted as far as the uterine fundus in accordance with the post-EBRT MR-assessed cavity length. The pre-EBRT MR-specified target volume was used for the dwell-length adjustment. The safety of the dwell-length adjustment was assessed in terms of treatment failure. The dwell-length adjustment was made in 248 of 366 total insertions with a dwell-length reduction of 5-55 mm (median 15 mm) at the corpus. Pelvic failure was identified in 22 patients with a 2-year pelvic disease-free survival rate of 75.6% but without evidence of failure at dwelling-skipped corpuses. Given after pelvic EBRT and ICRT of full-length dwelling in part, which may have eradicated possible subclinical extension, adjustment of the tandem-source dwell length to the MR-specified target volume appeared to be safe.

The overall implications for research and practice are to acknowledge virtual project management as very different to traditional project management and to address this difference.......Virtual projects are common with global competition, market development, and not least the financial crisis forcing organizations to reduce their costs drastically. Organizations therefore have to place high importance on ways to carry out virtual projects and consider appropriate practices...

  7. Project Management Yinyang: Coupling project success and client satisfaction

    2017-06-01

    Full Text Available Our research applies paradox theory to a project management construct to help project management researchers and practitioners understand the tensions that can exist between project success and client satisfaction. Our research highlights that although project success and client satisfaction are both present within a project management construct, they also belong to different functional systems. Project success and client satisfaction have different systemic-discourses and use different language games to convey information. These distinctions can create latent and sometimes salient tensions within the project management construct that project managers must understand, embrace, and work with. We have used a Grounded Theory (GT methodology to explore the lived experience of project managers, and from this have identified a phenomenon which we have termed project management yinyang. Project management yinyang is the state that exists when both project success and Client satisfaction are tightly coupled within the project management construct. Project management yinyang highlights that these two phenomena cannot be viewed as separate elements because the ‘seed’ of each exists within the other. And to truly achieve one, you must also achieve the other. Our findings indicate that in order to create project management yinyang the project manager must embrace a paradoxical yet holistic philosophy. They must understand the complementarity, interdependency, and structural coupling that exists between the positivist and interpretivist paradigms within the project management construct. They must understand how satisfaction (Yin and success (Yang are created through focus. Furthermore, they must understand how project management yinyang is separate from, but borne from, the convergence of the other two elements.

  18. The CAREM-25 project from the risk point of view

    International Nuclear Information System (INIS)

    Baron, J.H.

    1998-01-01

    The future use of the nuclear energy for electricity production is considered a possible alternative, mainly taking into account the high environmental impact of the fossil fuel alternatives (greenhouse effect, acid rain). In a worldwide context, however, it is desirable for the new nuclear power plants to be safer than the present ones. To demonstrate the safety level of a nuclear installation, the Risk Analysis (in fact, Probabilistic Safety Analysis) is an adequate tool, as it allows for the risk level quantification. The risk itself is composed of two factors, the first takes into account the probability associated with accidental sequences that release radioactive materials, the second takes into account the amount and consequences of such a release. In the present work, the reduction of both factors is faced, the probability by using simpler safety systems (inherently safe systems), and the consequence by using small power production units, that have, besides, passive mitigation systems and long response times. The work is illustrated with a risk comparison for electricity production via CAREM-25 units, against via a classic design unit (Atucha II). The results are base in Probabilistic Safety Studies performed for both installations. The conclusions show an effective risk reduction (both in probability and in consequence), reaching the point where in no case acute irradiation effects are predicted in the vicinity of the accidented plant.

    Safety standards and best practices do exist in the field of cryogenics but, as in most domains, they are generally inserted in a few ‘envelope’ cases commonly used in the industry, whereas applicability to the particularity of research facilities are not fully tailored to its needs. The main objective in these cases is to find a harmonised approach, based on lessons learnt and scientific knowledge. The Kryolize Project was created in order to produce tools with a harmonized approach to size pressure relief devices for cryogenic applications. In view of disseminating such tools to other institutes and industrial partners, the project was submitted to CERN’s KT Fund committee. This talk will focus on the process and deliverables of the KT-Funded Kryolize project, including the method on how to cope with the sizing of pressure relief devices and the R&D collaboration agreement between CERN and Karlsruhe Institute of Technology for an experimental programme.

  11. Shear modulus estimation on vastus intermedius of elderly and young females over the entire range of isometric contraction.

    Directory of Open Access Journals (Sweden)

    Cong-Zhi Wang

    Full Text Available Elderly people often suffer from sarcopenia in their lower extremities, which gives rise to the increased susceptibility of fall. Comparing the mechanical properties of the knee extensor/flexors on elderly and young subjects is helpful in understanding the underlying mechanisms of the muscle aging process. However, although the stiffness of skeletal muscle has been proved to be positively correlated to its non-fatiguing contraction intensity by some existing methods, this conclusion has not been verified above 50% maximum voluntary contraction (MVC due to the limitation of their measurement range. In this study, a vibro-ultrasound system was set up to achieve a considerably larger measurement range on muscle stiffness estimation. Its feasibility was verified on self-made silicone phantoms by comparing with the mechanical indentation method. The system was then used to assess the stiffness of vastus intermedius (VI, one of the knee extensors, on 10 healthy elderly female subjects (56.7 ± 4.9 yr and 10 healthy young female subjects (27.6 ± 5.0 yr. The VI stiffness in its action direction was confirmed to be positively correlated to the % MVC level (R2 = 0.999 over the entire range of isometric contraction, i.e. from 0% MVC (relaxed state to 100% MVC. Furthermore, it was shown that there was no significant difference between the mean VI shear modulus of the elderly and young subjects in a relaxed state (p > 0.1. However, when performing step isometric contraction, the VI stiffness of young female subjects was found to be larger than that of elderly participants (p < 0.001, especially at the relatively higher contraction levels. The results expanded our knowledge on the mechanical property of the elderly's skeletal muscle and its relationship with intensity of active contraction. Furthermore, the vibro-ultrasound system has a potential to become a powerful tool for investigating the elderly's muscle diseases.

  12. Engaging the Entire Care Cascade in Western Kenya: A Model to Achieve the Cardiovascular Disease Secondary Prevention Roadmap Goals.

    Vedanthan, Rajesh; Kamano, Jemima H; Bloomfield, Gerald S; Manji, Imran; Pastakia, Sonak; Kimaiyo, Sylvester N

    2015-12-01

    Cardiovascular disease (CVD) is the leading cause of death in the world, with a substantial health and economic burden confronted by low- and middle-income countries. In low-income countries such as Kenya, there exists a double burden of communicable and noncommunicable diseases, and the CVD profile includes many nonatherosclerotic entities. Socio-politico-economic realities present challenges to CVD prevention in Kenya, including poverty, low national spending on health, significant out-of-pocket health expenditures, and limited outpatient health insurance. In addition, the health infrastructure is characterized by insufficient human resources for health, medication stock-outs, and lack of facilities and equipment. Within this socio-politico-economic reality, contextually appropriate programs for CVD prevention need to be developed. We describe our experience from western Kenya, where we have engaged the entire care cascade across all levels of the health system, in order to improve access to high-quality, comprehensive, coordinated, and sustainable care for CVD and CVD risk factors. We report on several initiatives: 1) population-wide screening for hypertension and diabetes; 2) engagement of community resources and governance structures; 3) geographic decentralization of care services; 4) task redistribution to more efficiently use of available human resources for health; 5) ensuring a consistent supply of essential medicines; 6) improving physical infrastructure of rural health facilities; 7) developing an integrated health record; and 8) mobile health (mHealth) initiatives to provide clinical decision support and record-keeping functions. Although several challenges remain, there currently exists a critical window of opportunity to establish systems of care and prevention that can alter the trajectory of CVD in low-resource settings.

    2014-06-01

    Full Text Available Background: Observational instruments, such as the Rapid Entire Body Assessment, quickly assess biomechanical risks present in the workplace. However, in order to use these instruments, it is necessary to conduct the translational/cross-cultural adaptation of the instrument and test its measurement properties. Objectives: To perform the translation and the cross-cultural adaptation to Brazilian-Portuguese and test the reliability of the REBA instrument. Method: The procedures of translation and cross-cultural adaptation to Brazilian-Portuguese were conducted following proposed guidelines that involved translation, synthesis of translations, back translation, committee review and testing of the pre-final version. In addition, reliability and the intra- and inter-rater percent agreement were obtained with the Linear Weighted Kappa Coefficient that was associated with the 95% Confidence Interval and the cross tabulation 2×2. Results : The procedures for translation and adaptation were adequate and the necessary adjustments were conducted on the instrument. The intra- and inter-rater reliability showed values of 0.104 to 0.504, respectively, ranging from very poor to moderate. The percentage agreement values ranged from 5.66% to 69.81%. The percentage agreement was closer to 100% at the item 'upper arm' (69.81% for the Intra-rater 1 and at the items 'legs' and 'upper arm' for the Intra-rater 2 (62.26%. Conclusions: The processes of translation and cross-cultural adaptation were conducted on the REBA instrument and the Brazilian version of the instrument was obtained. However, despite the reliability of the tests used to correct the translated and adapted version, the reliability values are unacceptable according to the guidelines standard, indicating that the reliability must be re-evaluated. Therefore, caution in the interpretation of the biomechanical risks measured by this instrument should be taken.

    Background: Observational instruments, such as the Rapid Entire Body Assessment, quickly assess biomechanical risks present in the workplace. However, in order to use these instruments, it is necessary to conduct the translational/cross-cultural adaptation of the instrument and test its measurement properties.

  15. Soil organic carbon stocks assessment in Mediterranean natural areas: a comparison of entire soil profiles and soil control sections.

    Soil organic carbon (SOC) is an important part of the global carbon (C) cycle. In addition, SOC is a soil property subject to changes and highly variable in space and time. Over time, some researches have analyzed entire soil profile (ESP) by pedogenetic horizons and other researches have analyzed soil control sections (SCS) to different thickness. However, very few studies compare both methods (ESP versus SCS). This research sought to analyze the SOC stock (SOCS) variability using both methods (ESP and SCS) in The Despeñaperros Natural Park, a nature reserve that consists of a 76.8 km(2) forested area in southern Spain. Thirty-four sampling points were selected in the study zone. Each sampling point was analyzed in two different ways, as ESP (by horizons) and as SCS with different depth increments (0-25, 25-50, 50-75 and 75-100 cm). The major goal of this research was to study the SOCS variability at regional scale. The soils investigated in this study included Phaeozems, Cambisols, Regosols and Leptosols. Total SOCS in the Despeñaperros Natural Park was over 28.2% greater when SCS were used compared to ESP, ranging from 0.8144 Tg C (10,604.2 Mg km(-2)) to 0.6353 Tg C (8272.1 Mg km(-2)) respectively (1 Tg = 10(12) g). However, when the topsoil (surface horizon and superficial section control) was analyzed, this difference increased to 59.8% in SCS compared to ESP. The comparison between ESP and SCS showed the effect of mixing pedogenetic horizons when depth increments were analyzed. This indicates an overestimate of T-SOCS when sampling by SCS.

    Research is needed to validate lesions recorded at meat inspection as indicators of pig welfare on farm. The aims were to determine the influence of mixing pigs on carcass lesions and to establish whether such lesions correlate with pig behaviour and lesions scored on farm. Aggressive and mounting behaviour of pigs in three single sex pens was recorded on Day −5, −2, and −1 relative to slaughter (Day 0). On Day 0 pigs were randomly allocated to 3 treatments (n = 20/group) over 5 replicates: males mixed with females (MF), males mixed with males (MM), and males unmixed (MUM). Aggressive and mounting behaviours were recorded on Day 0 at holding on farm and lairage. Skin/tail lesions were scored according to severity at the farm (Day −1), lairage, and on the carcass (Day 0). Effect of treatment and time on behaviour and lesions were analysed by mixed models. Spearman rank correlations between behaviour and lesion scores and between scores recorded at different stages were determined. In general, MM performed more aggressive behaviour (50.4 ± 10.72) than MUM (20.3 ± 9.55, P carcass lesions and no associations were found with fighting/mounting. Mixing entire males prior to slaughter stimulated mounting and aggressive behaviour but did not influence carcass lesion scores. Carcass skin/tail lesions scores were correlated with scores recorded on farm (rskin = 0.21 and rtail = 0.18, P < 0.01) suggesting that information recorded at meat inspection could be used as indicators of pig welfare on farm.

    Full Text Available Ferramentas para auxílio de análise ergonômica são frequentemente utilizadas quando há a necessidade de avaliação de riscos musculoesqueléticos no trabalho. Dessas ferramentas, uma das mais conhecidas é a REBA (Rapid Entire Body Assessment. Seu amplo uso fez com que suas formas de distribuição e aplicação fossem alteradas por vários autores, de forma a tentar encontrar a melhor maneira de aplicação. Inclusive, com o advento de celulares e tablets, foram feitas diversas versões em aplicativo da ferramenta. Pouco pode ser encontrado sobre a usabilidade desse método, ainda mais em qual versão é mais apropriado, em termos de usabilidade. Objetivou-se neste artigo realizar uma avaliação de usabilidade da ferramenta REBA em duas diferentes versões para verificar a influência que a usabilidade da ferramenta tem nos seus resultados. Acredita-se que qualquer tipo de ferramenta para uma avaliação ergonômica deve, de forma intrínseca, ser usável, pois sua usabilidade tem influência direta em sua confiabilidade e replicabilidade. Sendo assim, fez-se uma análise comparativa de usabilidade com a ferramenta em versão papel e aplicativos para celular com oito sujeitos para a verificação de tal usabilidade. Encontrou-se melhor usabilidade para o aplicativo, mas confiabilidade equiparada para as duas versões. Assim, constata-se que as duas podem ser igualmente usadas para avaliação REBA.

    2016-01-01

    Full Text Available The aim of this paper is to review contemporary literature on selective mutism (SM, available in our language. The paper includes a contemporary definition of the disorder, previous studies of selective mutism, theories about its origin, and treatment. SM is a disorder that occurs in childhood, when a child's speech is selectively lacking in certain social situations. School is the context in which the disorder is typically manifested, which is why SM is often diagnosed only after children start school. The paper gives a historical account of changes in views on this disorder. Modern conceptions emphasize selective inability of children to spontaneously and successfully express themselves verbally. In researching SM, case studies on children who have selective mutism are most commonly published. Etiological factors are not precisely defined, and different conceptions give their interpretations depending on various theoretical frameworks. Some studies consistently indicate a relation between SM and social anxiety, and some with opposing behavior and delays in language development. Based on theoretical explanations of SM, psychological interventions (behavioral and cognitive-behavioral, psychodynamic and projective techniques, counseling and family therapy are created. Modern treatment of selective mutism includes an eclectic approach and emphasizes the role of teachers and school in general. Future studies should deepen the knowledge about selective mutism, specify the methodological procedure and stimulate the individualized treatment of children with SM.

    2004-10-01

    Around 80 years ago, several authors (for instance H. Weyl, T.Y. Thomas, J. Douglas and J.H.C. Whitehead) studied the projective geometry of paths, using the methods of tensor calculus. The principal object of study was a spray, namely a homogeneous second-order differential equation, or more generally a projective equivalence class of sprays. At around the same time, E. Cartan studied the same topic from a different point of view, by imagining a projective space attached to a manifold, or, more generally, attached to a `manifold of elements'; the infinitesimal `glue' may be interpreted in modern language as a Cartan projective connection on a principal bundle. This paper describes the geometrical relationship between these two points of view.

    On 30th January, when CERN still resembled a winter wonderland, a helicopter with a photographer on board took off on an aerial tour. One sunny morning at the end of January, when the area was waking up to an overnight snowfall, a helicopter took off from the Meyrin site with a CERN photographer on board. CERN has been the subject of aerial photographs ever since its creation. Although its appearance has changed over the years, the Laboratory has aged well. The aerial photographs taken during its fifty-year history bear witness to its expansion, showing how a handful of buildings and a first accelerator have blossomed into an entire machine complex. Let's take to the skies and have a look at some of the photos taken on this crisp January morning: a sight for sore eyes! In the foreground, Building 40 on the Meyrin site is recognisable from its magnet shape.On the right of the Route de Meyrin (crossing the photo diagonally), next to Point 1, the work on the Globe of Innovation, which got underway at the beg...

    A technique has been developed to use the renal window view for imaging the kidneys through the homogeneous tissues of the liver, the lower part of the heart and the upper part of the stomach. The projection is obtained by directing the X-ray beam obliquely through the infant or child so that the view of the kidneys is not obscured by any overlying bowel gas which would have created problems in conventional intravenous urography.

    This article reports the observations of correspondents for the Bulletin (two Russian journalists, one based in Moscow, the other in Kiev) who investigated the status of the Soviet Union's Black Sea Fleet and Ukraine's status as a non-nuclear-weapons state. After two years of wrangling and two earlier failed settlements, Russian President Boris Yeltsin met with Ukrainian President Leonid Kravchuk at Massandra in Crimea. On September 3, the leaders announced that Russia would buy out Ukraine's interest in the fleet and lease the port at Sevastopol. The Massandra summit was also supposed to settle Ukraine's status as a non-nuclear-weapons state. Described here are the Kiev-based correspondent's views on the Massandra summit (and its major topics), which was to have been called off by the Russian foreign ministry when Ukrainian Prime Minister Leonid Kuchma resigned

    A viewing device for observing objects in near-infrared false-color comprising a pair of goggles with one or more filters in the apertures, and pads that engage the face for blocking stray light from the sides so that all light reaching the user's eyes come through the filters. The filters attenuate most visible light and pass near-infrared (having wavelengths longer than approximately 700 nm) and a small amount of blue-green and blue-violet (having wavelengths in the 500 to 520 nm and shorter than 435 nm, respectively). The goggles are useful for looking at vegetation to identify different species and for determining the health of the vegetation, and to detect some forms of camouflage. 7 figs

    The presence of uranium in environment either natural or due to civil and military use, may lead to contamination of the public throughout the entire life mainly by chronic ingestion. The mechanisms of uranium transfer from alimentary bolus to blood are still not well known. In particular, few information are available on the different absorption sites along the gastrointestinal tract, the different cellular pathways (para-or trans-cellular), and the transporters implicated in the uranium absorption. In addition, the specific role of Peyer's patches, the aggregated structure of Gut-Associated Lymphoid tissue, in the intestinal transfer of uranium has never been determined. In fact, the transport of uranium through these structures specialized in antigen uptake from intestinal lumen may lead to major dysfunctions in mucosal immunity. Thus, different approaches have to be developed to determine the role of the different gastrointestinal structures and to apprehend the biological consequences of daily passage of uranium through these structures. These experiments include in vivo measurement of uranium in blood after in situ deposit of uranium (233U) in the different segments of the alimentary tract (buccal cavity, stomach, small intestine, colon) and ex vivo experiments in Using chambers to compare uranium passage from luminal to serosal side through intestinal epithelium and Peyer's patches. In vitro studies are also necessary to determine the nature of the cells as well as the transporters implicated in the gastrointestinal passage of uranium. Autoradiography experiments were performed to determine if uranium absorption was only restricted to villi which contained absorptive cells or if uranium absorption was also due to crypt cells. In addition, the transporter implicated in the uranium passage id dependent of the physico-chemical form of uranium present at the different gastrointestinal sites. When complexed to phosphate, uranium is transported by the sodium

    Full Text Available It is known that the so-called elementary symmetric polynomials $R_n(x = \\int_{[0,1]}(x(t^n\\,dt$ form an algebraic basis in the algebra of all symmetric continuous polynomials on the complex Banach space $L_\\infty,$ which is dense in the Fr\\'{e}chet algebra $H_{bs}(L_\\infty$ of all entire symmetric functions of bounded  type on $L_\\infty.$ Consequently, every continuous homomorphism $\\varphi: H_{bs}(L_\\infty \\to \\mathbb{C}$ is uniquely determined by the sequence $\\{\\varphi(R_n\\}_{n=1}^\\infty.$ By the continuity of the homomorphism $\\varphi,$ the sequence $\\{\\sqrt[n]{|\\varphi(R_n|}\\}_{n=1}^\\infty$ is bounded. On the other hand, for every sequence $\\{\\xi_n\\}_{n=1}^\\infty \\subset \\mathbb{C},$ such that the sequence $\\{\\sqrt[n]{|\\xi_n|}\\}_{n=1}^\\infty$ is bounded,  there exists  $x_\\xi \\in L_\\infty$ such that $R_n(x_\\xi = \\xi_n$ for every $n \\in \\mathbb{N}.$ Therefore, for the point-evaluation functional $\\delta_{x_\\xi}$ we have $\\delta_{x_\\xi}(R_n = \\xi_n$ for every $n \\in \\mathbb{N}.$ Thus, every continuous complex-valued homomorphism of $H_{bs}(L_\\infty$ is a point-evaluation functional at some point of $L_\\infty.$ Note that such a point is not unique. We can consider an equivalence relation on $L_\\infty,$ defined by $x\\sim y \\Leftrightarrow \\delta_x = \\delta_y.$ The spectrum (the set of all continuous complex-valued homomorphisms $M_{bs}$ of the algebra $H_{bs}(L_\\infty$ is one-to-one with the quotient set $L_\\infty/_\\sim.$ Consequently, $M_{bs}$ can be endowed with the quotient topology. On the other hand, it is naturally to identify $M_{bs}$ with the set of all sequences $\\{\\xi_n\\}_{n=1}^\\infty \\subset \\mathbb{C}$ such that the sequence $\\{\\sqrt[n]{|\\xi_n|}\\}_{n=1}^\\infty$ is bounded.We show that the quotient topology is Hausdorffand that $M_{bs}$ with the operation of coordinate-wise addition of sequences forms an abelian topological group.

    Introduction. With the purpose of implementing gated radiotherapy for lung cancer patients, this study investigated the interfraction variations in tumour size and internal displacement over entire treatment courses. To explore the potential of image guided radiotherapy (IGRT) the variations were measured using a set-up strategy based on imaging of bony landmarks and compared to a strategy using in room lasers, skin tattoos and cupper landmarks. Materials and methods. During their six week treatment course of 60Gy in 2Gy fractions, ten patients underwent 3 respiratory gated CT scans. The tumours were contoured on each CT scan to evaluate the variations in volumes and position. The lung tumours and the mediastinal tumours were contoured separately. The positional variations were measured as 3D mobility vectors and correlated to matching of the scans using the two different strategies. Results. The tumour size was significantly reduced from the first to the last CT scan. For the lung tumours the reduction was 19%, p=0.03, and for the mediastinal tumours the reduction was 34%, p=0.0007. The mean 3D mobility vector and the SD for the lung tumours was 0.51cm (+-0.21) for matching using bony landmarks and 0.85cm (+-0.54) for matching using skin tattoos. For the mediastinal tumours the corresponding vectors and SD's were 0.55cm (+-0.19) and 0.72cm (+-0.43). The differences between the vectors were significant for the lung tumours p=0.004. The interfractional overlap of lung tumours was 80-87% when matched using bony landmarks and 70-76% when matched using skin tattoos. The overlap of the mediastinal tumours were 60-65% and 41-47%, respectively. Conclusions. Despite the use of gating the tumours varied considerably, regarding both position and volume. The variations in position were dependent on the set-up strategy. Set-up using IGRT was superior to set-up using skin tattoos.

  12. Luck, Policy or Something Else Entirely? Vietnam’s Economic Performance in 2009 and Prospects for 2010

    Directory of Open Access Journals (Sweden)

    Adam J. Fforde

    Full Text Available Vietnam’s economic performance in 2009 is seen by the Vietnamese government and representatives of the Western donor communities as good, with the effects of the global financial crisis relatively mild. The paper notes a lack of contestation of these mainstream views and locates them within an assessment of major trends in 2009, and medium-term issues. Particular focus is placed upon the policy implications of rural development and the need for a strong rationalisation of the state sector. Remarks upon the political economy of change then permit comments upon interactions between economic performance and gathering social and political concern with the political challenges of transition to so-called ‘middle income’ status, which in many countries has posed novel and tricky problems of adjustment, often requiring major social and political adjustments that have not always been successful. The paper concludes by suggesting that, as in the past, Vietnam’s style of change finds some things easy and others hard, and that this has its reflection in economic policy and performance.

    1980-05-15

    A schematized description is given of the different stages in the project. The aim is to show the development of the project and the strategies which have been chosen. The four different stages in the project are treated from the following points of view: the reasons for the choice of material models; the determination of model properties; and the control of the calculated values. In the origin plan for the project it was stated to only use a joint element model. However, it was shown to be a reasonable strategy to use both a general linear elastic model and a geometric restricted model with joint elements. During the course of the Project's development stages, it was found that a reduction in the number of rock types could be made without loss of generality. A modified strategy is suggested based on more studies of the rock bahavior and less advanced calculations in the first stages of the project.

    The Nile basin River system spans 3 million km(exp 2) distributed over ten nations. The eight upstream riparian nations, Ethiopia, Eretria, Uganda, Rwanda, Burundi, Congo, Tanzania and Kenya are the source of approximately 86% of the water inputs to the Nile, while the two downstream riparian countries Sudan and Egypt, presently rely on the river's flow for most of the their needs. Both climate and agriculture contribute to the complicated nature of Nile River management: precipitation in the headwaters regions of Ethiopia and Lake Victoria is variable on a seasonal and inter-annual basis, while demand for irrigation water in the arid downstream region is consistently high. The Nile is, perhaps, one of the most difficult trans-boundary water issue in the world, and this study would be the first initiative to combine NASA satellite observations with the hydrologic models study the overall water balance in a to comprehensive manner. The cornerstone application of NASA's Earth Science Research Results under this project are the NASA Land Data Assimilation System (LDAS) and the USDA Atmosphere-land Exchange Inverse (ALEXI) model. These two complementary research results are methodologically independent methods for using NASA observations to support water resource analysis in data poor regions. Where an LDAS uses multiple sources of satellite data to inform prognostic simulations of hydrological process, ALEXI diagnoses evapotranspiration and water stress on the basis of thermal infrared satellite imagery. Specifically, this work integrates NASA Land Data Assimilation systems into the water management decision support systems that member countries of the Nile Basin Initiative (NBI) and Regional Center for Mapping of Resources for Development (RCMRD, located in Nairobi, Kenya) use in water resource analysis, agricultural planning, and acute drought response to support sustainable development of Nile Basin water resources. The project is motivated by the recognition that

    2016-06-01

    Full Text Available Aging is currently stimulating intense interest of both researchers and the general public. In developed countries, the average life expectancy has increased by roughly 30 years within the last century, and human senescence has been delayed by around a decade. Although aging is arguably the most familiar aspect of human biology, its proximate and ultimate causes have not been elucidated fully and understood yet. Nowadays there are two main approaches to the ultimate causes of aging. These are deterministic and stochastic models. The proximate theories constitute a distinct group of explanations. They focus on mechanistic causes of aging. In this view, there is no reason to believe that there is only one biological mechanism responsible for aging. The aging process is highly complex and results from an accumulation of random molecular damage. Currently, the disposable soma theory (DST, proposed by Thomas Kirkwood, is the most influential and coherent line of reasoning in biogerontology. This model does not postulate any particular mechanism underpinning somatic defense. Therefore, it is compatible with various models, including mechanistic and evolutionary explanations. Recently, however, an interesting theory of hyper-function of mTOR as a more direct cause of aging has been formulated by Mikhail Blagosklonny, offering an entirely different approach to numerous problems and paradoxes in current biogerontology. In this view, aging is quasi-programmed, which means that it is an aimless continuation of developmental growth. This mTOR-centric model allows the prediction of completely new relationships. The aim of this article is to present and compare the views of both parties in the dispute, based on the results of some recent experimental studies, and the contemporary knowledge of selected major aspects of human aging and longevity

    [figure removed for brevity, see original site] Left-eye view of a color stereo pair for PIA11977 [figure removed for brevity, see original site] Right-eye view of a color stereo pair for PIA11977 NASA's Mars Exploration Rover Spirit used its navigation camera to take the images combined into this stereo, 210-degree view of the rover's surroundings during the 1,861st to 1,863rd Martian days, or sols, of Spirit's surface mission (March 28 to 30, 2009). This view combines images from the left-eye and right-eye sides of the navigation camera. It appears three-dimensional when viewed through red-blue glasses with the red lens on the left. The center of the scene is toward the south-southwest. East is on the left. West-northwest is on the right. The rover had driven 22.7 meters (74 feet) southwestward on Sol 1861 before beginning to take the frames in this view. The drive brought Spirit past the northwestern corner of Home Plate. In this view, the western edge of Home Plate is on the portion of the horizon farthest to the left. A mound in middle distance near the center of the view is called 'Tsiolkovsky' and is about 40 meters (about 130 feet) from the rover's position. This view is presented as a cylindrical-perspective projection with geometric seam correction.

    To compare the advantages of single-versus two-view follow-up screening mammograms, oblique and craniocaudal examinations from 1,000 asymptomatic women who had prior normal baseline studies were reviewed retrospectively, first using only the oblique projection, then using the oblique and craniocaudal views. Single-view readings of dense breasts resulted in considerably more abnormal interpretations then were made with two-view readings. The induced costs from these false-positive readings more than offset the small savings in operating expense of single-view reading. In contradistinction, so few false-positive readings were made in women with fatty breasts (in whom superimposition of dense tissue is not a problem) that savings in operating expense exceeded induced costs

    In high resolution (microscopic) CT applications, the scan field of view should cover the entire specimen or sample to allow complete data acquisition and image reconstruction. However, truncation may occur in projection data and results in artifacts in reconstructed images. In this study, we propose a low resolution image constrained reconstruction algorithm (LRICR) for interior tomography in microscopic CT at high resolution. In general, the multi-resolution acquisition based methods can be employed to solve the data truncation problem if the project data acquired at low resolution are utilized to fill up the truncated projection data acquired at high resolution. However, most existing methods place quite strict restrictions on the data acquisition geometry, which greatly limits their utility in practice. In the proposed LRICR algorithm, full and partial data acquisition (scan) at low and high resolutions, respectively, are carried out. Using the image reconstructed from sparse projection data acquired at low resolution as the prior, a microscopic image at high resolution is reconstructed from the truncated projection data acquired at high resolution. Two synthesized digital phantoms, a raw bamboo culm and a specimen of mouse femur, were utilized to evaluate and verify performance of the proposed LRICR algorithm. Compared with the conventional TV minimization based algorithm and the multi-resolution scout-reconstruction algorithm, the proposed LRICR algorithm shows significant improvement in reduction of the artifacts caused by data truncation, providing a practical solution for high quality and reliable interior tomography in microscopic CT applications. The proposed LRICR algorithm outperforms the multi-resolution scout-reconstruction method and the TV minimization based reconstruction for interior tomography in microscopic CT.

    Full Text Available Introduction. Nowadays, the use of information and communication technologies (ICT has become an integral part both of every individual’s life and of the society in general. It is no longer possible to deny the impact of virtual environment on socialisation and development of the identity of young people. In this regard, the investigation of young people’s view on virtual social networks, and the possibility of students’ own competitiveness realization through various web services. The aim of the research presented in the article is to study the factors of students’ assessment of virtual social networks as a tool of personal fulfillment. Methodology and research methods. Content analysis and synthesis of scientific publications studies were carried out at a theoretical stage of the research; secondary sampling analysis of sociologic data material sources was conducted. The empirical research stage involved the instrument of questionnaire surveys, statistical data processing and interpretation of the results. Results and scientific novelty. The social survey conducted in 2017 with the participation of 1087 high school students and 1196 college students of the Tyumen Region shown that the more competitive students consider themselves, the more competitive they perceive the people having great popularity on the Internet. At that, compared to girls, young people are more inclined to consider the people having great popularity on the Internet competitive. It is determined that having a popular virtual media account for the young person is less worthwhile than for female respondents. The author explains this fact: male representatives regard it as “social capital” which can contribute to growth of their competitiveness in society as well as to achieve some profit. The author concludes that youth views on competitiveness are not directly related to the activity in virtual social networks. Frequent use by respondents of the Internet and

Results indicate that synoptic viewing causes the largest plastic effect. Monocular blur scores lower than synoptic viewing but is still rated significantly higher than the baseline conditions. The results strengthen the idea that synoptic viewing is not due to a placebo effect. Furthermore, monocular blur has been verified for the first time as a way of experiencing the plastic effect, although the effect is smaller than synoptic viewing. We discuss the results with respect to the theoretical basis for the plastic effect. We show that current theories are not described with sufficient details to explain the differences we found.

    This paper is the result of five years of experience with the nuclear world in Switzerland (five Swiss nuclear plants) from the point of view of a journalist, who doesn't pretend to know everything; who is neither scientific nor a technical journalist, he is writing for the man in the street, and works for a daily paper i.e. has to work very fast and as close to the reality as possible. Understanding and mutual confidence between the nuclear industry and media is emphasised as essential. 'Nuclear' people are specialists and are warned about the fact that they are dealing with non-specialists, journalists and the public who would like to understand what are the processes that might affect them and do not have a dictionary of technical terminology at hand. It is pointed out that the nuclear industry should speak openly about problems and accept being criticised if they want to restore confidence with the media and with the public

    Dutch radiodiagnostics viewed internationally. - A quantitative description of diagnostic radiology is given in terms of radiological density (the number of radiological examinations per 1000 inhibitants), consumptions of roentgen film and contrast media. The data concerning examinations were recorded by a yearly inquiry system addressing all Dutch radiologists. The consumption of film and contrast media were derived from the data banks of the industries. In comparing these data with the data for Western Europe, Japan and the United States it is remarkable that diagnostic radiology scores lowest in regard to density, film consumption and use of contrast media. Only in the use of 35 mm cinefilm (coronary angiography) is The Netherlands number 2 on the list preceded by the United States. As a consequence radiation exposure of the population caused by diagnostic radiology is low in The Netherlands. Although the technical condition of the equipment is good due to regular and preventive service the life-span of the radiological equipment is gradually increasing beyond the limits of the normal economic depreciation. Growing arrears are found in the application of new technology: ultrasound, computer tomography and magnetic resonance imaging. The substitution of high osmolar contrast media by low osmolar media is also laggin gbehind. (author). 10 refs.; 1 fig.; 4 tab

    The personal experiences at the Beijing Fourth World Conference on Women and the Nongovernmental Organization (NGO) Forum were described by a Chinese American veterinarian. The author became aware that women were primarily the persons living in poverty in the world. Business and government appeared more concerned with economic growth. As a consequence, developed countries with 20% of world population consume 80% of the world's resources. The privilege of money secures a position of power in the world, power to buy up the resources of the world. This process is unsustainable and inequitable. Women are viewed as key players in shifting the balance in favor of a higher quality of life. The NGO workshops on Women in Livestock Development (WILD) was run by women veterinarians, who worked at the local level with women in poor areas. WILD operates out of offices in Arkansas in the USA. WILD women work in Sichuan, China, among the Han and Tibetans in increasing family income through heifer and livestock production. Conference participants from WILD programs talked about their experiences with increased income and loans to other women. The World Women's Veterinary Association members, who attended the conference, visited a small animal clinic in Beijing run by the Agriculture Ministry, and Beijing Agricultural University and its Veterinary Teaching Hospital. Demonstrations were given of small animal acupuncture. The author found the conference to be a success and found that press reports misrepresented the energy generated by the meeting.

    On paper, plans are most often technically "correct". But a large percentage of implementations fail - due to delay, missed targets or lack of sustainability. The most common pitfall is neglect of the "soft" side of change. All implementation projects imply change, and successful change requires leadership. What separates leaders from managers is the ability to engage and excite stakeholders, to lead by example and to drive the change agenda. In my opinion most people will be part of change if they understand the need for change, have the adequate competences to perform in their new role and have the right incentives. Therefore leaders that are able to communicate the need for change, provide for adequate training and aligned incentives will be most successful. In addition, leaders that engage and motivate their employees through role modelling and personal involvement will not only succeed in implementation - they will thrive.

    Managing complex projects requires a capable, effective project manager to be in place, who is assisted by a team of competent assistants in various relevant disciplines. This team of assistants is known as the Integrated Project Team (IPT). he IPT is composed of a multidisciplinary group of people who are collectively responsible for delivering a defined project outcome and who plan, execute, and implement over the entire life-cycle of a project, which can be a facility being constructed or a system being acquired. An ideal IPT includes empowered representatives from all functional areas involved with a project-such as engineering design, technology, manufacturing, test and evaluation, contracts, legal, logistics, and especially, the customer. Effective IPTs are an essential element of scope, cost, and schedule control for any complex, large construction project, whether funded by DOE or another organization. By recently assessing a number of major, on-going DOE waste management projects, the characteristics of high performing IPTs have been defined as well as the reasons for potential IPT failure. Project managers should use IPTs to plan and execute projects, but the IPTs must be properly constituted and the members capable and empowered. For them to be effective, the project manager must select the right team, and provide them with the training and guidance for them to be effective. IPT members must treat their IPT assignment as a primary duty, not some ancillary function. All team members must have an understanding of the factors associated with successful IPTs, and the reasons that some IPTs fail. Integrated Project Teams should be used by both government and industry. (authors)

  18. Assessment of probabilistic areal reduction factors of precipitations for the entire French territory with gridded rainfall data.

    The starting point of our study was the availability of maps of rainfall quantiles available for the entire French mainland territory at the spatial resolution of 1 km². These maps display the rainfall amounts estimated for different rainfall durations (from 15 minutes to 72 hours) and different return periods (from 2 years up to 1 000 years). They are provided by a regionalized stochastic hourly point rainfall generator, the SHYREG method which was previously developed by Irstea (Arnaud et al., 2007; Cantet and Arnaud, 2014). Being calibrated independently on numerous raingauges data (with an average density across the country of 1 raingauge per 200 km²), this method suffers from a limitation common to point-process rainfall generators: it can only reproduce point rainfall patterns and has no capacity to generate rainfall fields. It can't hence provide areal rainfall quantiles, the estimation of the latter being however needed for the construction of design rainfall or for the diagnostic of observed events. One means of bridging this gap between our local rainfall quantiles and areal rainfall quantiles is given by the concept of probabilistic areal reduction factors of rainfall (ARF) as defined by Omolayo (1993). This concept enables to estimate areal rainfall of a particular frequency within a certain amount of time from point rainfalls of the same frequency and duration. Assessing such ARF for the whole French territory is of particular interest since it should allow us to compute areal rainfall quantiles, and eventually watershed rainfall quantiles, by using the already available grids of statistical point rainfall of the SHYREG method. Our purpose was then to assess these ARF thanks to long time-series of spatial rainfall data. We have used two sets of rainfall fields: i) hourly rainfall fields from a 10-year reference database of Quantitative Precipitation Estimation (QPE) over France (Tabary et al., 2012), ii) daily rainfall fields resulting from a 53-year

    Sky view factor (SVF), which is an indicator of urban canyon geometry, affects the surface energy balance, local air circulation, and outdoor thermal comfort. This study focused on a continuous and long-term meteorological observation system to investigate the effects of SVF on outdoor thermal conditions and physiological equivalent temperature (PET) in the central business district (CBD) of Beijing (which is located within Chaoyang District), specifically addressed current knowledge gaps for SVF-PET relationships in cities with typical continental/microthermal climates. An urban sub-domain scale model and the RayMan model were used to diagnose wind fields and to calculate SVF and long-term PET, respectively. Analytical results show that the extent of shading contributes to variations in thermal perception distribution. Highly shaded areas (SVF 0.5), and vice versa. Because Beijing has a monsoon-influenced humid continental climate with hot summers and long, cold, windy, and dry winters, a design project that ideally provides moderate shading should be planned to balance hot discomfort in summer and cold discomfort in winter, which effectively prolongs the comfort periods in outdoor spaces throughout the entire year. This research indicate that climate zone characteristics, urban environmental conditions, and thermal comfort requirements of residents must be accounted for in local-scale scientific planning and design, i.e., for urban canyon streets and residential estates.

  1. An approach of long-view tomosynthesis in peripheral arterial angiographic examinations

    Tomosynthesis (TS) has been evaluated as a useful diagnostic imaging tool for the orthopedic market and lung cancer screening. Previously, we proposed Long-View Tomosynthesis (LVTS) to apply further clinical application by expanding the reconstructed region of TS. LVTS method consists of three steps. First, it acquires multiple images while X-ray tube and Flat Panel Detector (FPD) are moving in the same linear direction simultaneously at a constant speed. Second, each image is divided into fixed length strips, and then the strips from different images having similar X-ray beam trajectory angles are stitched together. Last, multi slice coronal images are reconstructed by utilizing the Filtered Back Projection (FBP) technique from the long stitched images. The present LVTS method requires the acquisition by the constant speed motion to stitch each strip precisely. It is necessary to improve the LVTS method to apply peripheral angiographic examinations that are usually acquired at arbitrary variable speeds to chase the contrast media in the blood vessel. We propose adding the method of detecting the moved distance of frames along with anatomical structure and the method of selecting pixel values with contrast media to stitching algorithm. As a result, LVTS can extract new clinical information like 3-D structure of superficial femoral arteries and the entire blood vessel from images already acquired by routine bolus chasing techniques.

The capability of OLAP database software systems to handle data complexity comes at a high price for analysts, presenting them a combinatorially vast space of views of a relational database. We respond to the need to deploy technologies sufficient to allow users to guide themselves to areas of local structure by casting the space of 'views' of an OLAP database as a combinatorial object of all projections and subsets, and 'view discovery' as an search process over that lattice. We equip the view lattice with statistical information theoretical measures sufficient to support a combinatorial optimization process. We outline 'hop-chaining' as a particular view discovery algorithm over this object, wherein users are guided across a permutation of the dimensions by searching for successive two-dimensional views, pushing seen dimensions into an increasingly large background filter in a 'spiraling' search process. We illustrate this work in the context of data cubes recording summary statistics for radiation portal monitors at US ports.

    We report on the work done in massively parallel processing with a view to studying possible solutions for extracting interesting high-energy physics particle events at future high-luminosity hadronic colliders operating in the TeV energy domain. We concentrate on a special Single Instruction Multiple Data (SIMD) architecture: the Associative String Processor (ASP). The Massively Parallel Processing Collaboration (MPPC) Project, grouping nine European institutes, was launched by CERN to carry out this RandD programme. This report, written by partners of the MPPC collaboration, describes the main results achieved at the end of the project: construction of ASP machines, parallel software development and application studies in high-energy physics and in other fields of science. A final, positive assessment of the ASP concept has been made by the Collaboration. (orig.)

    Over the past three years the 2010 in Vienna founded Ludwig Boltzmann Institute for Archaeological Prospection and Virtual Archaeology (http://archpro.lbg.ac.at), in collaboration with its ten European partner organizations, has made considerable progress in the development and application of near-surface geophysical survey technology and methodology mapping square kilometres rather than hectares in unprecedented spatial resolution. The use of multiple novel motorized multichannel GPR and magnetometer systems (both Förster/Fluxgate and Cesium type) in combination with advanced and centimetre precise positioning systems (robotic totalstations and Realtime Kinematic GPS) permitting efficient navigation in open fields have resulted in comprehensive blanket coverage archaeological prospection surveys of important cultural heritage sites, such as the landscape surrounding Stonehenge in the framework of the Stonehenge Hidden Landscape Project, the mapping of the World Cultural Heritage site Birka-Hovgården in Sweden, or the detailed investigation of the Roman urban landscape of Carnuntum near Vienna. Efficient state-of-the-art archaeological prospection survey solutions require adequate fieldwork methodologies and appropriate data processing tools for timely quality control of the data in the field and large-scale data visualisations after arrival back in the office. The processed and optimized visualisations of the geophysical measurement data provide the basis for subsequent archaeological interpretation. Integration of the high-resolution geophysical prospection data with remote sensing data acquired through aerial photography, airborne laser- and hyperspectral-scanning, terrestrial laser-scanning or detailed digital terrain models derived through photogrammetric methods permits improved understanding and spatial analysis as well as the preparation of comprehensible presentations for the stakeholders (scientific community, cultural heritage managers, public).

The first study is correlational; we found decreased recidivism rates among prisoners trained by Freedom Project compared with recidivism rates in Washington state. The second study compared trained prisoners with a matched-pair control group and found improvement in self-reported anger, self-compassion, and certain forms of mindfulness among the trained group. Ratings of role-plays simulating difficult interactions show increased social skills among the group trained by Freedom Project than in the matched controls.

    To compare the advantages of one- versus two-views mammography, screening films were reviewed from 1,500 asymptomatic women undergoing mammography. Two separate interpretations were made of each case, one using only the oblique projection images, the other using both oblique and cranio caudal views. In women with dense breasts, one view readings resulted in much more frequent abnormal interpretations, false positives, than two-views readings. In contrast, in woman with primary fatty breast, in whom superimposition of dense tissue on image is not a problem, it may be reasonable to obtain a single mediolateral projection to follow-up screening mammography.

    1991-01-01

    Since Japan is entirely dependent on imports to meet its demand for uranium, its foremost consideration is security of supply. From this point of view, the long-term strategy for uranium procurement followed by the Japanese Government and utilities can be summarized in four points; diversification of supply sources, long term contracts, holding of sufficient inventory and self-supply (ie. involvement in exploration activity and mine development). Under this basic strategy, Japanese utilities have made decisions on which suppliers they buy uranium from, and which purchasing method to adopt, based on the principles of securing stable sources of supply and stable prices. This position is reviewed and discussed. (author)

    2017-09-01

    Vibrations are a very typical feature of all compressors and are given great attention in the industry. The reason for this interest is primarily the negative influence that it can have on both the operating staff and the entire machine's service life. The purpose of this work is to describe the methodology of screw compressor analysis from a vibration point-of-view. This analysis is an essential part of the design of vibro-diagnostics of screw compressors with regard to their service life.

    When a planar shape is viewed obliquely, it is deformed by a perspective deformation. If the visual system were to pick up geometrical invariants from such projections, these would necessarily be invariant under the wider class of projective transformations. To what extent can the visual system tell the difference between perspective and nonperspective but still projective deformations of shapes? To investigate this, observers were asked to indicate which of two test patterns most resembled a...

    1995-04-01

    Various approaches to the Rorschach Technique are described in terms of the idiographic-nomothetic axis and the perceptual-content axis. It is suggested that it is most productive to view the Rorschach as a projective tool, with perceptual scoring a secondary factor. Current efforts at objectification of the Rorschach are not seen as useful as efforts to enhance its projective qualities. Some possible ways are discussed in which the projective value of the instrument can be maximized.

  6. Impact of Chinese Culture on Pre-service Science Teachers' Views of the Nature of Science

    Wan, Dongsheng; Zhang, Hongshia; Wei, Bing

    2018-04-01

    This study examines Chinese pre-service teachers' (N = 30) views on the nature of science (NOS) and how Chinese culture influences their views. Participants were from two teachers' universities in eastern China. As an exploratory and interpretive study, a scenario-based interview approach was adopted. The results indicated that the participants held unique views about the five key aspects of NOS. Many participants have alternative and contemporary views of NOS, but few possess classical views. In fact, teachers adopted features of the Confucian Doctrine of the Mean either consciously or unconsciously to account for their views of NOS. This research reflects that the Doctrine of the Mean affected Chinese teachers' views of NOS, making them rather deficient in their understandings of classical NOS. Based on empirical data, it is argued that science teacher training in China should focus on the content and objectives of classical NOS, rather than just teaching contemporary views of NOS. Taking Chinese culture into consideration, science teacher education in China cannot entirely import the strategies of teaching the classical views of NOS from the developed world, but should develop, design and contextualize local strategies that are suitable for the training of Chinese science teachers. Some issues for further investigation of learners' views of NOS in non-Western contexts are suggested as implications from this study.

  7. Project mobilisation

    This paper identifies and reviews the issues to be addressed and the procedures to be followed during the mobilisation of projects using LFG as an energy source. Knowledge of the procedures involved in project mobilisation, their sequence and probable timescales, is essential for efficient project management. It is assumed that the majority of projects will be situated on existing, licensed landfill sites and, in addition to complying with the relevant conditions of the waste management licence and original planning consent, any proposed developments on the site will require a separate planning consent. Experience in the UK indicates that obtaining planning permission rarely constitutes a barrier to the development of schemes for the utilisation of LFG. Even so, an appreciation of the applicable environmental and planning legislation is essential as this will enable the developer to recognise the main concerns of the relevant planning authority at an early stage of the project, resulting in the preparation of an informed and well-structured application for planning permission. For a LFG utilisation scheme on an existing landfill site, the need to carry out an environmental assessment (EA) as part of the application for planning permission will, in vitually all cases, be discretionary. Even if not deemed necessary by the planning authority, an EA is a useful tool at the planning application stage, to identify and address potential problems and to support discussions with bodies such as the Environment Agency, from whom consents or authorisations may be required. Carrying out an EA can thus provide for more cost-effective project development and enhanced environmental protection. Typically, the principal contractual arrangements, such as the purchase of gas or the sale of electricity, will have been established before the project mobilisation phase. However, there are many other contractural arrangements that must be established, and consents and permits that may be

  8. The STAPL pView

    2011-01-01

    The Standard Template Adaptive Parallel Library (STAPL) is a C++ parallel programming library that provides a collection of distributed data structures (pContainers) and parallel algorithms (pAlgorithms) and a generic methodology for extending them to provide customized functionality. STAPL algorithms are written in terms of pViews, which provide a generic access interface to pContainer data by abstracting common data structure concepts. Briefly, pViews allow the same pContainer to present multiple interfaces, e.g., enabling the same pMatrix to be \\'viewed\\' (or used) as a row-major or column-major matrix, or even as a vector. In this paper, we describe the stapl pView concept and its properties. pViews generalize the iterator concept and enable parallelism by providing random access to, and an ADT for, collections of elements. We illustrate how pViews provide support for managing the tradeoff between expressivity and performance and examine the performance overhead incurred when using pViews. © 2011 Springer-Verlag Berlin Heidelberg.

    To report and evaluate the application of entire gastrointestinal barium meal combined with multi-temporal abdominal films in the diagnosis of patients with intestinal neuronal dysplasia type B (IND type B). Thirty-six patients with symptoms of long-standing constipation were enrolled in this study. The study took place at the Department of General Surgery, Xiangyang Central Hospital, Hubei Province, China from July 2007 to October 2012. All of them had already been subjected to the tests of barium enema and anorectal manometry and were suspected to be IND type B, but were not confirmed by mucous membrane acetylcholinesterase determination. All underwent the entire gastrointestinal barium meal combined with multi-temporal abdominal films. The data was collected and then analyzed retrospectively. After entire gastrointestinal barium meal combined with multi-temporal abdominal films, 30 out of 36 cases in this group were diagnosed with intestinal neuronal diseases, and then were treated with appropriate surgical treatment. The postoperative pathological diagnosis was IND type B. The other 6 patients in this group still could not be diagnosed explicitly after the test; thus, we treated them with conservative treatment. Entire gastrointestinal barium meal combined with multi-temporal abdominal films has the advantage of being able to test the gastrointestinal transfer capabilities and to find physiological and pathological changes simultaneously. It could provide important proof for the diagnosis of patients with intestinal neuronal dysplasia type B.

    Full Text Available With CT (computed tomography chest gaining more importance as a diagnostic tool, chest X-ray especially the lateral view is taken less commonly nowadays. Besides CT chest is also proven to be superior to chest X-ray in patients with major blunt trauma. We are presenting a 68-year old male who was partially treated from outside for a left sided pneumonia. He came to our hospital because of persisting chest pain. Chest X-ray, frontal view (postero-anterior was almost normal except for a mild opacity in the left lower zone. CT scan of the chest revealed a fluid collection posteriorly enclosed within enhancing pleura. Chest X-ray, left lateral view showed a corresponding posterior pleural based opacity. We are presenting this case to highlight the importance of the lateral view of the chest X-ray. In selected cases there is still a role for the lateral view. With the three dimensional visualization provided by the CT, the lateral view of the chest may be easier to understand. Consequent to the initial diagnosis by CT further follow up can be done with the chest X-ray. In a limited way this mitigates unnecessary expenditure and more importantly prevents the patient from exposure to harmful radiation in the form of repeated CT.

    The declining cost of many renewable energy technologies and changes in the prices of fossil fuels have recently encouraged governments policies to subsidize the use of biomass as a sustainable source of energy. Deciduous poplars (Populus spp.) trees are often selected for biomass production in short rotation coppiced (SRC) for their high CO2 photosynthetic assimilation rates and their capacity to develop dense canopies with high values of leaf area index (LAI). So far, observations and projections of seasonal variations of many VOC fluxes has been limited to strong isoprenoids emitting evergreen ecosystems such tropical and Mediterranean forests as well as Citrus and oil palm plantation, all having constant values of LAI. We run a long-term field campaign where the exchange of VOC, together with CO2 and water vapor was monitored during an entire growing season (June - November, 2012) above a SRC-based poplar plantation. Our results confirmed that isoprene and methanol were the most abundant fluxes emitted, accounting for more than 90% of the total carbon released in form of VOC. However, Northern climates characterized by fresh summertime temperatures and recurring precipitations favored poplar growth while inhibiting the development of isoprene emission that resulted in only 0.7% of the net ecosystem carbon exchange (NEE). Besides, measurements of a multitude of VOC fluxes by PTR-TOF-MS showed bi-directional exchange of oxygenated-VOC (OVOC) such as: formaldehyde, acetaldehyde, acetone, isoprene oxidation products (iox, namely MVK, MAC and MEK) as well as ethanol and formic acid. The application of Self Organizing Maps to visualize the relationship between the full time-series of many VOC fluxes and the observed seasonal variations of environmental, physiological and structural parameters proved the most abundant isoprene ad methanol fluxes to occur mainly on the hottest days under mid-high light intensities when also NEE and evapotraspiration reached the highest

    The first Antarctic Imaging Campaign (AIC) occurred during the period September 9, 1997 through October 20, 1997. The AIC utilized the unique attributes of the Canadian RADARSAT-1 to acquire the first, high-resolution, synthetic aperture imagery covering the entire Antarctic Continent. Although the primary goal of the mission was the acquisition of image data, the nearly flawless execution of the mission enabled additional collections of exact repeat orbit data. These data, covering an extensive portion of the interior Antarctic, potentially are suitable for interferometric analysis of topography and surface velocity. This document summarizes the Project through completion with delivery of products to the NASA DAACs.

  19. A broader view of justice.

    Science.gov (United States)

    Jecker, Nancy S

    2008-10-01

    In this paper I argue that a narrow view of justice dominates the bioethics literature. I urge a broader view. As bioethicists, we often conceive of justice using a medical model. This model focuses attention at a particular point in time, namely, when someone who is already sick seeks access to scarce or expensive services. A medical model asks how we can fairly distribute those services. The broader view I endorse requires looking upstream, and asking how disease and suffering came about. In contrast to a medical model, a social model of justice considers how social determinants affect the health of a population. For example, social factors such as access to clean drinking water, education, safe workplaces, and police protection, profoundly affect risk for disease and early death. I examine one important social determinant of health, health care coverage, to show the limits of a medical model and the merits of a broader view.
