    1998-01-01

    The Waste Management Program is pleased to issue the Fiscal Year 1998 Progress Report presenting program highlights and major accomplishments of the last year. This year-end update describes the current initiatives in waste management and the progress DOE has made toward their goals and objectives, including the results of the waste management annual performance commitments. One of the most important program efforts continues to be opening the Waste Isolation Pilot Plant (WIPP), located near Carlsbad, New Mexico, for the deep geologic disposal of transuranic waste. A major success was achieved this year by the West Valley Demonstration Project in New York, which in June completed the project's production phase of high-level waste processing ahead of schedule and under budget. Another significant accomplishment this year was the award of two privatization contracts for major waste management operations, one at Oak ridge for transuranic waste treatment, and one at Hanford for the Tank Waste Remediation System privatization project. DOE is proud of the progress that has been made, and will continue to pursue program activities that allow it to safely and expeditiously dispose of radioactive and hazardous wastes across the complex, while reducing worker, public, and environmental risks

    Full Text Available Research aiming to describe the actions that were developed by the Extension Project "Let's breastfeed, Mom?" During the 21 years of its performance in Jequié / Bahia and identify the difficulties, facilities and progress of the project. This is a descriptive, quantitative-qualitative study. The data were collected in the archived project documents, analyzed through descriptive statistics and content analysis. The results showed that 8,923 registered postpartum women with educational activities and 1,313 domiciliary visits were carried out, as the main actions carried out by the project. The difficulties were: lack of consumer / permanent materials and human resources; As facilities: responsibility and commitment of the members of the project, as well as the support of the transportation service of the institution. The advances were the elaboration of the research project, with insertion of research fellows, creation of the webpage and the logo. It is necessary to reflect on the difficulties and propose measures to remedy them and thus continue to contribute to the promotion, protection and support of breastfeeding in the Municipality, contributing to the reduction of infant morbidity and mortality

    To examine the progression pattern of myopic maculopathy. Retrospective, observational case series. Highly myopic patients who had been followed up for 10 years or more. Using fundus photographs, myopic features were differentiated according to Meta-analysis of Pathologic Myopia (META-PM) Study Group recommendations. Progression pattern of maculopathy. The study included 810 eyes of 432 patients (mean age, 42.3±16.8 years; mean axial length, 28.8±1.9 mm; mean follow-up, 18.7±7.1 years). The progression rate of myopic maculopathy was 47.0 per 1000 eye-years. Within the pathologic myopia (PM) group (n = 521 eyes), progression of myopic maculopathy was associated with female gender (odds ratio [OR], 2.21; P = 0.001), older age (OR, 1.03; P = 0.002), longer axial length (OR, 1.20; P = 0.007), greater axial elongation (OR, 1.45; P = 0.005), and development of parapapillary atrophy (PPA; OR, 3.14; P < 0.001). Diffuse atrophy, found in 217 eyes without choroidal neovascularization (CNV) or lacquer cracks (LCs) at baseline, progressed in 111 (51%) eyes, leading to macular diffuse atrophy (n = 64; 64/111 or 58%), patchy atrophy (n = 59; 53%), myopic CNV (n = 18; 16%), LCs (n = 9; 5%), and patchy-related macular atrophy (n = 3; 3%). Patchy atrophy, detected in 63 eyes without CNV or LCs at baseline, showed progression in 60 eyes (95%), leading to enlargement of original patchy atrophy (n = 59; 59/60 or 98%), new patchy atrophy (n = 29; 48%), CNV-related macular atrophy (n = 13; 22%), and patchy-related macular atrophy (n = 5; 8%). Of 66 eyes with LCs, 43 eyes (65%) showed progression with development of new patchy atrophy (n = 38; 38/43 or 88%) and new LCs (n = 7; 16%). Reduction in best-corrected visual acuity (BCVA) was associated mainly (all P < 0.001) with the development of CNV or CNV-related macular atrophy and enlargement of macular atrophy. The most frequent progression patterns were an extension of peripapillary diffuse atrophy to macular diffuse

    Full Text Available U.S. Naval Medical Research Unit No. 2 Detachment (NAMRU, in collaboration with National Institute of Health Research and Development (NIHRD and many other Indonesian government agencies and universities, has conducted studies of malaria throughout Java, Sumatra, Sulawesi, Kalimantan, Flores, Timor, and Irian Jaya. Most studies have characterized the disease epidemiologically by defining the parasitologic distribution of the disease in the population, and by defining the entomologic parameters of local transmission. Studies of patterns of resistance to antimalarials have also been done at many field sites. Several studies on the clinical management of malaria occurred in Rumah Sakit Umum Propinsi in Jayapura. In addition to these studies which impact upon local public health planning policy, immunologic studies routinely occurred in support of the global effort to develop a vaccine against malaria. This report summarizes the progress made in these areas of research during the first 20 years of NAMRU in Indonesia.

  6. 50 years of progress in NDT worldwide

    Farley, J.M.

    2013-01-01

    The paper is focussed on the progress which has been made over 50 years in the science, technology and application of NDT, particularly in relation to inspection of welds and safety critical components used in mining, oil and gas offshore, pipelines, power generation, petrochemical, shipbuilding, pulp and paper, mineral processing, and defence industries - both during manufacture and in-service. New techniques not dreamt of 50 years ago and new technology such as personal computers, lasers and robotics which are now common-place in everyday life have transformed some aspects of NDT. But other aspects have remained unchanged, including the continued use of the more basic NDT methods and the challenges of recruitment, training, certification and motivation of personnel. There have been major changes in the world scene over 50 years including the globalisation of trade, the emergence of new countries as industrial powers, and the ageing of safety critical infrastructure. These have impacted on NDT business and on the activities of the international NDT community (including ICNDT, the International Committee for NDT). The paper will conclude by introducing the activities championed by ICNDT to promote the understanding of the importance of NDT, to support the development of NDT Societies around the world, to educate users on the correct use of personnel certification and to pursue the objective of global harmonisation and recognition of third party certification.

    The 3-year accelerated aging study of the SAVY-4000 O-ring shows very little evidence of significant degradation to samples subjected to aggressive elevated temperature and radiation conditions. Whole container thermal aging studies followed by helium leakage testing and compression set measurements were used to establish an estimate for a failure criterion for O-ring compression set of ?65 %. The whole container aging studies further show that the air flow and efficiency functions of the filter do not degrade significantly after thermal aging. However, the degradation of the water-resistant function leads to water penetration failure after four months at 210°C, but does not cause failure after 10 months at 120°C (130°C is the maximum operating temperature for the PTFE membrane). The thermal aging data for O-ring compression set do not meet the assumptions of standard time-temperature superposition analysis for accelerated aging studies. Instead, the data suggest that multiple degradation mechanisms are operative, with a reversible mechanism operative at low aging temperatures and an irreversible mechanism dominating at high aging temperatures. To distinguish between these mechanisms, we have measured compression set after allowing the sample to physically relax, thereby minimizing the effect of the reversible mechanism. The resulting data were analyzed using two distinct mathematical methods to obtain a lifetime estimate based on chemical degradation alone. Both methods support a lifetime estimate of greater than 150 years at 80°C. Although the role of the reversible mechanism is not fully understood, it is clear that the contribution to the total compression set is small in comparison to that due to the chemical degradation mechanism. To better understand the chemical degradation mechanism, thermally aged O-ring samples have been characterized by Fourier Transform Infrared (FTIR), Electron Paramagnetic Resonance (EPR), Gel Permeation Chromatography (GPC), and

    2017-05-01

    To summarize the progress of larger flexion gap than extension gap in total knee arthro-plasty (TKA). The domestic and foreign related literature about larger flexion gap than extension gap in TKA, and its impact factors, biomechanical and kinematic features, and clinical results were summarized. During TKA, to adjust the relations of flexion gap and extension gap is one of the key factors of successful operation. The biomechanical, kinematic, and clinical researches show that properly larger flexion gap than extension gap can improve both the postoperative knee range of motion and the satisfaction of patients, but does not affect the stability of the knee joint. However, there are also contrary findings. So adjustment of flexion gap and extension gap during TKA is still in dispute. Larger flexion gap than extension gap in TKA is a new joint space theory, and long-term clinical efficacy, operation skills, and related complications still need further study.

    We investigated our surgical strategy and clinical results in patients from active infective endocarditis (AIE) complicated by paravalvular involvement to determine the risk factors of early and late death and reoperation. From October 1979 to December 2014, 955 patients underwent operations for AIE; among them 207 had AIE with paravalvular extension. The patients were a mean age of 59.9 ± 15.4 years, and 162 (78%) were male. Of these patients, 137 (66%) had isolated aortic valve endocarditis, and 138 (67%) had native valve endocarditis. Follow-up was 99% complete. The operative mortality of the cohort was 16% (n = 34). Abnormal communication, mechanical valve implantation, and renal failure were independent predictors of 30-day death. Survival at 1, 5, 10, and 15 years was 90.3% ± 2.3%, 62.4% ± 3.7%, 49.3% ± 4.1%, and 37.9% ± 4.4%, respectively. Streptococcus endocarditis (all species), complex annular repair, and preoperative heart failure were independent predictors of long-term death. A reoperation was required in 29 patients (14%). Streptococcus pneumoniae endocarditis was the only independent predictor of early reoperation (within 30 days after the operation or during the same hospitalization). Freedom from reoperation at 1, 5, 10, and 15 years was 91.9% ± 2.2%, 89.6% ± 2.6%, 89.6% ± 2.6%, and 87.0% ± 3.5%, respectively. Independent predictors of late reoperation were urgent/emergency operation, prosthetic valve endocarditis, and complex annular repair. AIE complicated by paravalvular involvement remains a surgical challenge. Valve replacement (particularly using bioprosthesis) associated with ad hoc reconstruction seems to be a reliable option and showed very encouraging results in this context.

    2001-10-01

    To review the progress made over the past decade with regard to the treatment of enuresis and encopresis, as well as advances in the understanding of etiological mechanisms. Separate computerized literature (English language only) searches of Medline and PsycINFO databases were conducted under the parameter of enuresis and children-adolescents, as well as encopresis and children-adolescents. There has been a substantial decrease in published research concerning the use of imipramine to treat enuresis compared with the prior two decades, accompanied by a corresponding increase in the number of papers concerning desmopressin acetate (DDAVP), which has become the primary pharmacological treatment. Genetic studies of large pedigrees have further confirmed the importance of heritable factors. With regard to encopresis, the research has focused primarily on pathophysiological factors related to the colon and anal sphincter. The widespread use of DDAVP has been the primary addition to treatment strategies over the past decade. The bell-and-pad method of conditioning, the only major treatment that has enduring benefit after being withdrawn, is the most cost-effective and appears to be underutilized. Research into etiological mechanisms has focused primarily on the mechanism of action of DDAVP and advances in the understanding of genetic factors. Advances in the treatment and etiological understanding of encopresis have been less impressive.

    Full Text Available In 1981, the reported number of cases of typhoid fever in Indonesia was 19,596, increasing to 26,606 m 1986, most of the increase was due to improved detection and recognition of the pathogen. A more realistic estimate of incidence for this underreported and underdiagnosed disease would be from 540,000 to 1,210,000 cases per year. This was based on results of a household survey done by Budiarso R. et al. in 1980 and 1986, and on result of a community surveillance done by Ruwido and Simanjuntak et al. from 1983-1988. These studies were done in Plaju, South Sumatera, representing an urban area and Paseh, West Java, representing a semi-rural area. The results showed that the incidence rate of typhoid fever in the semi rural area was 358/100,000 population/year, and between 760-810/100,000 population/year in the urban area. These studies also indicated that the high risk group in the population was school age children between ages of 3-19 years. From other observations, it is also noted that the case fatality in urbanized and growing areas of Indonesia, may be higher than it is reported in other areas of the world

    Rattlesnake is a MOOSE-based radiation transport application developed at INL to support modern multi-physics simulations. At the beginning of the last year, Rattlesnake was able to perform steady-state, transient and eigenvalue calculations for the multigroup radiation transport equations. Various discretization schemes, including continuous finite element method (FEM) with discrete ordinates method (SN) and spherical harmonics expansion method (PN) for the self-adjoint angular flux (SAAF) formulation, continuous FEM (CFEM) with SN for the least square (LS) formulation, diffusion approximation with CFEM and discontinuous FEM (DFEM), have been implemented. A separate toolkit, YAKXS, for multigroup cross section management was developed to support Rattlesnake calculations with feedback both from changes in the field variables, such as fuel temperature, coolant density, and etc., and in isotope inventory. The framework for doing nonlinear diffusion acceleration (NDA) within Rattlesnake has been set up, and both NDA calculations with SAAF-SN-CFEM scheme and Monte Carlo with OpenMC have been performed. It was also used for coupling BISON and RELAP-7 for the full-core multiphysics simulations. Within the last fiscal year, significant improvements have been made in Rattlesnake. Rattlesnake development was migrated into our internal GITLAB development environment at the end of year 2014. Since then total 369 merge requests has been accepted into Rattlesnake. It is noted that the MOOSE framework that Rattlesnake is based on is under continuous developments. Improvements made in MOOSE can improve the Rattlesnake. It is acknowledged that MOOSE developers spent efforts on patching Rattlesnake for the improvements made on the framework side. This report will not cover the code restructuring for better readability and modularity and documentation improvements, which we have spent tremendous effort on. It only details some of improvements in the following sections.

  18. Fifty years of progress in acoustic phonetics

    Science.gov (United States)

    Stevens, Kenneth N.

    2004-10-01

    Three events that occurred 50 or 60 years ago shaped the study of acoustic phonetics, and in the following few decades these events influenced research and applications in speech disorders, speech development, speech synthesis, speech recognition, and other subareas in speech communication. These events were: (1) the source-filter theory of speech production (Chiba and Kajiyama; Fant); (2) the development of the sound spectrograph and its interpretation (Potter, Kopp, and Green; Joos); and (3) the birth of research that related distinctive features to acoustic patterns (Jakobson, Fant, and Halle). Following these events there has been systematic exploration of the articulatory, acoustic, and perceptual bases of phonological categories, and some quantification of the sources of variability in the transformation of this phonological representation of speech into its acoustic manifestations. This effort has been enhanced by studies of how children acquire language in spite of this variability and by research on speech disorders. Gaps in our knowledge of this inherent variability in speech have limited the directions of applications such as synthesis and recognition of speech, and have led to the implementation of data-driven techniques rather than theoretical principles. Some examples of advances in our knowledge, and limitations of this knowledge, are reviewed.

  19. Systemic Chemotherapy for Progression of Brain Metastases in Extensive-Stage Small Cell Lung Cancer

    2015-01-01

    Full Text Available Lung cancer is the most common cause of cancer related mortality in men and women. Approximately 15% of lung cancers are small cell type. Chemotherapy and radiation are the mainstay treatments. Currently, the standard chemotherapy regimen includes platinum/etoposide. For extensive small cell lung cancer, irinotecan and cisplatin have also been used. Patients with relapsed small cell lung cancer have a very poor prognosis, and the morbidity increases with brain metastases. Approximately 10%–14% of small cell lung cancer patients exhibit brain metastases at the time of diagnosis, which increases to 50%–80% as the disease progresses. Mean survival with brain metastases is reported to be less than six months, thus calling for improved regimens. Here we present a case series of patients treated with irinotecan for progressive brain metastases in small cell lung cancer, which serves as a reminder of the role of systemic chemotherapy in this setting.

  1. The first year: A cultural shift towards improving student progress

    Directory of Open Access Journals (Sweden)

    Becky Jobe

    2016-03-01

    Full Text Available Student attrition has been a primary focus among higher education institutions for nearly 50 years, yet overall retention and graduation rates continue to be of significant concern. Despite increased attention, ongoing struggles of colleges and universities to effectively address potential barriers to student progress are well-documented.  Part of the challenge lies in garnering widespread organizational commitment that establishes student progress as an institutional priority.  Along with leadership commitment, broad institutional involvement and adherence to a systematic approach to testing new, innovative solutions are necessary to better position the institution to make clear, evidence-based decisions that improve the student experience. The purpose of this manuscript is to detail one university’s cultural shift towards establishing a clear student progress strategy (with particular focus on the first year, and the methodological approach that laid the foundation for a multi-year study of initiatives that resulted in improved student satisfaction, performance, and retention.

  3. Progress of Cometary Science in the Past 100 Years

    Sekanina, Zdenek

    1999-01-01

    Enormous strides made by cometary science during the 20th century defy any meaningful comparison of its state 100 years ago and now. The great majority of the subfields enjoying much attention nowadays did not exist in the year 1900. Dramatic developments, especially in the past 30-50 years, have equally affected observational and theoretical studies of comets. The profound diversification of observing techniques has been documented by the ever widening limits on the electromagnetic spectrum covered. While the time around 1900 marked an early period of slow and painful experimentation with photographic methods in cometary studies, observations of comets from the x-ray region to the radio waves have by now become routine. Many of the new techniques, and all those involved with the wavelengths shorter than about 300 nm, were made possible by another major breakthrough of this century - observing from space. Experiments on dedicated Earth-orbiting satellites as well as several deep-space probes have provided fascinating new information on the nature and makeup of comets. In broader terms, much of the progress has been achieved thanks to fundamental discoveries and major advances in electronics, whose applications resulted in qualitatively new instruments (e.g. radiotelescopes) and sensors or detectors (e.g. CCD arrays). The most universal effect on the entire cometary science, from observing to data handling to quantitative interpretations, has been, as in any other branch of science, due to the introduction of electronic computers, with their processing capabilities not only unheard of, but literally unimaginable, in the age of classical desk calculators. As if all this should not be enough, the today's generations of comet scientists have, in addition, been blessed with nature's highly appreciated cooperation. Indeed, in the span of a dozen years, between 1985 and 1997, we were privileged to witness four remarkable cometary events: (i) a return of Halley

    2011-01-01

    Brand extensions, or new product introductions under an existing brand name, have become increasingly popular over the past 20 years. Marketers tout brand extensions as enjoying higher market share and profitability than launching new brand names that require exorbitant advertising expenditures (Smith & Park 1992). According to some estimates, brand extensions account for more than 90% of new product introductions in some categories (Volckner & Sattler 2002). However, one study found that 27%...

  6. Unusual progression of herpes simplex encephalitis with basal ganglia and extensive white matter involvement

    Full Text Available We report a 51-year old male with herpes simplex encephalitis (HSE showing unusual progression and magnetic resonance (MR findings. The initial neurological manifestation of intractable focal seizure with low-grade fever persisted for three days, and rapidly coma, myoclonic status, and respiratory failure with high-grade fever emerged thereafter. The polymerase chain reaction (PCR result of cerebrospinal fluid (CSF was positive for HSV-1 DNA. In the early stage, MR images (MRI were normal. On subsequent MR diffusion-weighted (DW and fluid-attenuated inversion recovery (FLAIR images, high-intensity areas first appeared in the left frontal cortex, which was purely extra-temporal involvement, and extended into the basal ganglia, then the white matter, which are relatively spared in HSE. Antiviral therapy and immunosuppressive therapy did not suppress the progression of HSE, and finally severe cerebral edema developed into cerebral herniation, which required emergency decompressive craniectomy. Histological examination of a biopsy specimen of the white matter detected perivascular infiltration and destruction of basic structure, which confirmed non specific inflammatory change without obvious edema or demyelination. The present case shows both MR and pathological findings in the white matter in the acute stage of HSE.

  7. High Energy Physics Group. Annual progress report, fiscal year 1983

    International Nuclear Information System (INIS)

    1983-01-01

    Perhaps the most significant progress during the past twelve months of the Hawaii experimental program, aside from publication of results of earlier work, has been the favorable outcome of several important proposals in which a substantial fraction of our group is involved: the Mark II detector as first-up at the SLC, and DUMAND's Stage I approval, both by DOE review panels. When added to Fermilab approval of two neutrino bubble-chamber experiments at the Tevatron, E632 and E646, the major part of the Hawaii experimental program for the next few years is now well determined. Noteworthy in the SLAC/SLC/Mark II effort is the progress made in developing silicon microstrip detectors with microchip readout. Results from the IMB(H) proton decay experiment at the Morton Salt Mine, although not detecting proton decay, set the best lower limit on the proton's lifetime. Similarly the Very High Energy Gamma Ray project is closely linked with DUMAND, at least in principle, since these gammas are expected to arise from pi-zero decay, while the neutrinos come from charged meson decay. Some signal has been seen from Cygnus X-3, and other candidates are being explored. Preparations for upgrading the Fermilab 15' Bubble Chamber have made substantial progress. Sections of the Progress Report are devoted to VAX computer system improvements, other hardware and software improvements, travel in support of physics experiments, publications and other public reports, and last analysis of data still being gleaned from experimental data taken in years past (PEP-14 and E546, E388). High energy physics theoretical research is briefly described

    2015-01-01

    Full Text Available Objectives: The effects of first-line chemotherapy on overall survival (OS might be confounded by subsequent therapies in patients with small cell lung cancer (SCLC. We examined whether progression-free survival (PFS, post-progression survival (PPS, and tumor response could be valid surrogate endpoints for OS after first-line chemotherapies for patients with extensive SCLC using individual-level data. Methods: Between September 2002 and November 2012, we analyzed 49 cases of patients with extensive SCLC who were treated with cisplatin and irinotecan as first-line chemotherapy. The relationships of PFS, PPS, and tumor response with OS were analyzed at the individual level. Results: Spearman rank correlation analysis and linear regression analysis showed that PPS was strongly correlated with OS (r = 0.97, p < 0.05, R 2 = 0.94, PFS was moderately correlated with OS (r = 0.58, p < 0.05, R 2 = 0.24, and tumor shrinkage was weakly correlated with OS (r = 0.37, p < 0.05, R 2 = 0.13. The best response to second-line treatment, and the number of regimens employed after progression beyond first-line chemotherapy were both significantly associated with PPS ( p ≤ 0.05. Conclusion: PPS is a potential surrogate for OS in patients with extensive SCLC. Our findings also suggest that subsequent treatment after disease progression following first-line chemotherapy may greatly influence OS.

    The brain reserve hypothesis links larger maximal lifetime brain growth (MLBG, estimated with intracranial volume [ICV]) with lower risk for cognitive decline/dementia. We examined whether larger MLBG is also linked to less physical disability progression over 5 years in a prospective sample of treatment-naive patients with multiple sclerosis (MS). Physical disability was measured with the Expanded Disability Status Scale (EDSS) at baseline and 5-year follow-up in 52 treatment-naive Serbian patients with MS. MRI measured disease burden (cerebral atrophy, T2 lesion volume) and MLBG: a genetically determined, premorbid (established during adolescence, stable thereafter) patient characteristic estimated with ICV (adjusted for sex). Logistic regression tested whether MLBG (smaller vs larger) predicts disability progression (stable vs worsened) independently of disease burden. Disability progression was observed in 29 (55.8%) patients. Larger MLBG predicted lower risk for progression (odds ratio 0.13, 95% confidence interval 0.02-0.78), independently of disease burden. We also calculated absolute change in EDSS scores, and observed that patients with smaller MLBG showed worse EDSS change (0.91 ± 0.71) than patients with larger MLBG (0.42 ± 0.87). Larger MLBG was linked to lower risk for disability progression in patients with MS over 5 years, which is the first extension of the brain reserve hypothesis to physical disability. MLBG (ICV) represents a clinically available metric that may help gauge risk for future disability in patients with MS, which may advance the science and practice of early intervention. Potential avenues for future research are discussed. © 2016 American Academy of Neurology.

    The management of retinopathy of prematurity (ROP) can be challenging in preterm babies with a gestational age premature infant presented with "hybrid" zone 1 disease in the right eye and aggressive posterior ROP in the left eye. Both eyes were adequately treated with laser photocoagulation; however, the eyes deteriorated and progressed to stage 4 ROP. Both eyes eventually underwent intravitreal bevacizumab followed by lens sparing vitrectomy with good anatomical and visual outcome. Anticipation of progression despite laser photocoagulation in certain clinical scenarios, frequent follow-up and timely surgical intervention is paramount.

  13. Finding First-Year Success in Extension: Navigating Stakeholders Needs and Institutional Expectations

    Full Text Available Functioning within a defined administrative framework and meeting the needs of the stakeholders are essential in an Extension appointment. The first day of employment starts the promotion and tenure clock. It is the responsibility of the new Extension professional to take immediate steps to move forward with development of programming and application of the skill set that they bring to the job. Finding success in the first year of an Extension appointment revolves around understanding the expectations of the institution and the needs of the stakeholders. Once the institutional expectations and programming needs are understood, formulating a strategy that includes plans of work and logic models, measurement of outcomes and impacts, team building, professional development, peer mentoring, grant writing, and scholarship will provide a foundation for first year success in Extension. A willingness to follow a timely and systematic approach to meeting the expectations of the institution and stakeholders will provide for an efficient transition and relieve many of the stressors associated with a new appointment. This paper is based primarily on the author’s first year experience as an Extension faculty member and summarizes several best practices.

  14. Fifty years of progress in speech coding standards

    Science.gov (United States)

    Cox, Richard

    2004-10-01

    Over the past 50 years, speech coding has taken root worldwide. Early applications were for the military and transmission for telephone networks. The military gave equal priority to intelligibility and low bit rate. The telephone network gave priority to high quality and low delay. These illustrate three of the four areas in which requirements must be set for any speech coder application: bit rate, quality, delay, and complexity. While the military could afford relatively expensive terminal equipment for secure communications, the telephone network needed low cost for massive deployment in switches and transmission equipment worldwide. Today speech coders are at the heart of the wireless phones and telephone answering systems we use every day. In addition to the technology and technical invention that has occurred, standards make it possible for all these different systems to interoperate. The primary areas of standardization are the public switched telephone network, wireless telephony, and secure telephony for government and military applications. With the advent of IP telephony there are additional standardization efforts and challenges. In this talk the progress in all areas is reviewed as well as a reflection on Jim Flanagan's impact on this field during the past half century.

    2004-01-01

    The year 2004 is now coming to an end and has proven to be 'A Year of Progress' at the Cernavoda 2 nuclear project. Staffing levels have reached their peak in all departments with the exception of Commissioning. The Management Team (MT) now has more than 1600 staff employed. There are 18 contractors working on the site, 3 Romanian Engineering organizations working out of Bucharest and countless manufacturers supplying materials for 2500 Romanian domestic orders, 440 Romanian International orders, 400 Canadian orders and 212 Italian orders. To date the project has met all milestones, most notably in 2004 was the First Energization of the Station Service Transformer in October, marking the start of the commissioning program. The Primary Heat Transport piping was completed ahead of schedule, and installation of the Stand-by Diesel Generators were effected. The D 2 O up-grader building was erected, the Main Moderator pumps, piping and heat exchangers were installed, and the Main Control Room was completed with the majority of the panels installed including the Digital Control Computers. By the end of the year 12 of the more than 290 systems will have been transferred from Construction to Commissioning and the overall project will be approximately 78% complete. A significant event for the year was the approval of the EURATOM loan, which provides financial stability for the remainder of the project. The request for the first draw against this loan has been made and disbursement is expected early in the New Year. There were problems that had to be overcome during the year. Securing qualified construction contractor's staff and qualified vendors has proven to be a major challenge. The introduction of electronic management tools in the Management organization has required significant training and inputting of a backlog of data. Refurbishment of existing equipment on all safety systems and materials has placed an added demand on resources and delays in having material

    In a thirty-one-year-old female patient from the French West Indies with osseous sarcoidosis we were able to compare the value of three diagnostic procedures used to evaluate the skeleton: roentgenography. Tc99 m scintigraphy and Ga67 scintigraphy. The lesions of sarcoidosis involved mainly the bones of the hands and feet, but also one ankle, one wrist, both knees and the skull vault. Tc99 m proved the most sensitive procedure. Ga67 evidenced the active foci in the bones and neighboring soft tissues. Roentgenograms of the bones were the least informative. Anomalies in the metabolism of calcium were lacking, as shown by the normal PAK test, a fact that demonstrates that specific bone lesions do not play a significant part in the genesis of the increased urinary calcium excretion and hyper-calcemia found in sarcoidosis [fr

    The EES pilot program was initiated in August 1977, when 10 states were selected on a competitive basis for participation. The pilot states (Alabama, Connecticut, Michigan, New Mexico, Pennsylvania, Tennessee, Texas, Washington, Wisconsin, and Wyoming) devoted the first 6 months to start-up activities. This document is a follow-up report to the three volume Evaluation Summary of the first year of the pilot EES program published in September 1979. The purpose of this report is to provide an overview of the impacts and costs of the two years of the pilot program, and to check the consistency of findings over the two year period. The analysis addresses the following: (1) were the impact findings of Year I and Year II consistent, or did Year I and Year II attitudes and behavior vary. If variation existed, could it be attributed to program changes as the EES progressed from a start-up phase (Year I) to more normal service delivery (Year II); and (2) did costs of service delivery change (again reflecting start-up and normal service delivery costs). Did cost changes affect conclusions about the relative cost effectiveness of delivering services to different target audiences.

    The aim was to review the use and indications of cultured allogenic keratinocytes (CAlloK) in extensive burns and their efficiency. This retrospective study comprised 15 years (1997-2012). all patients who received CAlloK. patients who died before complete healing. Evaluation criteria were clinical. Time and success of wound healing after CAlloK use were evaluated. The CAlloK were used for 2 indications - STSG donor sites and deep 2nd degree burns in extensively burned patients. A total of 70 patients were included with severity Baux score of 99.2 (from 51 to 144) and mean percentage of TBSA of 63.49% (from 21 to 96%). Fifty nine patients received CAlloK for STSG donor sites with a mean number of applications of 4 and mean surface of 3800 cm(2) per patient. Treated donor sites were re-harvested 2.5 times. The mean time of complete epithelialization was 7 days. In 11 patients, CAlloK were used for deep 2nd degree burns. The mean percentage of burned surface was 73.7%. The mean surface of CAlloK per patient was 2545 cm(2). Complete healing was achieved in 6.4 days. The CAlloK allow rapid healing of STSG donor-sites and deep 2nd second degree burns in extensively burned patients. Copyright © 2013 Elsevier Ltd and ISBI. All rights reserved.

    The importance of metallurgy for social and economic development is indisputable. Although copper (Cu) was essential for the wealth of pre- and post-colonial societies in the Andes, the onset of extensive Cu metallurgy in South America is still debated. Comprehensive archaeological findings point to first sophisticated Cu metallurgy during the Moche culture ~200-800 AD, whereas peat-bog records from southern South America suggest earliest pollution potentially from Cu smelting as far back as ~2000 BC. Here we present a 6500-years Cu emission history for the Andean Altiplano, based on ice-core records from Illimani glacier in Bolivia, providing the first complete history of large-scale Cu smelting activities in South America. We find earliest anthropogenic Cu pollution during the Early Horizon period ~700-50 BC, and attribute the onset of intensified Cu smelting in South America to the activities of the central Andean Chiripa and Chavin cultures ~2700 years ago. This study provides for the first time substantial evidence for extensive Cu metallurgy already during these early cultures.

    2012-06-28

    The Fermi Gamma-ray Space Telescope was launched into orbit in June 2008, and is conducting a multi-year gamma-ray all-sky survey, using the main instrument on Fermi, the Large Area Telescope (LAT). Fermi began its science mission in August 2008, and has now been operating for almost 4 years. The SLAC National Accelerator Laboratory hosts the LAT Instrument Science Operations Center (ISOC), which supports the operation of the LAT in conjunction with the Mission Operations Center (MOC) and the Fermi Science Support Center (FSSC), both at NASA's Goddard Space Flight Center. The LAT has a continuous output data rate of about 1.5 Mbits per second, and data from the LAT are stored on Fermi and transmitted to the ground through TDRS and the MOC to the ISOC about 10 times per day. Several hundred computers at SLAC are used to process LAT data to perform event reconstruction, and gamma-ray photon data are subsequently delivered to the FSSC for public release with a few hours of being detected by the LAT. We summarize the current status of the LAT, and the evolution of the data processing and monitoring performed by the ISOC during the first 4 years of the Fermi mission, together with future plans for further changes to detected event data processing and instrument operations and monitoring.

    During the first 50 years of the American Vacuum Society (1953-2003), technology has advanced greatly. But the most impressive and conspicuous advance has been in computational power, due to the exponential increase in computing power at an exponentially decreasing cost per function. Many of our readers will remember the 'Macro-Mechanical System' called a slide rule that was symbolic of engineers and scientists in the 1950s and 1960s. From the slide rule of the past to today's desktop and notebook computers, possessing speed, storage, and power capability that dwarf the mainframes of the recent past, what a transformation!

  19. Adoption research, practice, and societal trends: Ten years of progress.

    Adoption involves the legal transfer of parental rights and responsibilities from a child's birth parents to adults who will raise the child (Reitz & Watson, 1992). Research related to adoption has expanded over the past 10 years and has incorporated more focus on implications for practice and public policy. This expansion has reflected increased awareness of the lived experience of adopted individuals, in addition to that of adoptive families and birth or first parents and families, collectively known as the adoption kinship network (Grotevant & McRoy, 1998). Trends discussed included research and social trends or movements (2007-2017) since the publication of the final article in a series of articles in the psychological literature related to adoption in The Counseling Psychologist (Baden & Wiley, 2007; Lee, 2003; O'Brien & Zamostny, 2003; Wiley & Baden, 2005; Zamostny, O'Brien, Baden, & Wiley, 2003; Zamostny, Wiley, O'Brien, Lee, & Baden, 2003). This article summarizes the social trends and research related to adoption over the last 10 years, including longitudinal and meta-analytic studies, increased research and conceptualization of ethnic and racial identity development, research on microaggressions, and research on diverse adoptive families, including those with gay and lesbian parents. Social trends included increased knowledge related to Internet accessibility, genetic information, continued focus on openness, and viewing adoption through a more critical lens. Implications are discussed for the development of programs that enhance competence of mental health professionals and adoption professionals in adoption-competent practice.

    Climate change and the urgency of decarbonizing the built environment are driving technological innovation in the way we deliver thermal comfort to occupants. These changes, in turn, seem to be setting the directions for contemporary thermal comfort research. This article presents a literature review of major changes, developments, and trends in the field of thermal comfort research over the last 20 years. One of the main paradigm shift was the fundamental conceptual reorientation that has taken place in thermal comfort thinking over the last 20 years; a shift away from the physically based determinism of Fanger's comfort model toward the mainstream and acceptance of the adaptive comfort model. Another noticeable shift has been from the undesirable toward the desirable qualities of air movement. Additionally, sophisticated models covering the physics and physiology of the human body were developed, driven by the continuous challenge to model thermal comfort at the same anatomical resolution and to combine these localized signals into a coherent, global thermal perception. Finally, the demand for ever increasing building energy efficiency is pushing technological innovation in the way we deliver comfortable indoor environments. These trends, in turn, continue setting the directions for contemporary thermal comfort research for the next decades. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    2005-01-01

    A case of extensive lower limb lengthening (32 cm) in a 14-year-old male patient with Ollier's disease is reported. A varus deformity of the femur and a valgus deformity of the tibia were evident. The femur was successfully lengthened 22 cm by metaphyseal distraction, and the tibia was lengthened 10 cm by two-stage distraction-compression method with a cylindrical bone allograft. Ilizarov's distraction device was used. Radiologically, a good bone regenerate was formed. Host bone has incorporated (like sarcophagi) the allograft of tibia. No evidence of vascular or neural disturbances was found. The lengthening indices were counted for femur 22.5 days per centimeter and for tibia 21 days per centimeter, altogether 15.5 days per centimeter. Bone lengthening was performed through the Ollier's disease foci. Fine needle biopsy investigation showed that most embryonic cartilage cells had been replaced with bone tissue. After five years and a 25-year follow-up the patient was satisfied with the result. The function of the knee joint was limited, but the limb was fully weight-bearing. Signs of knee osteoarthritis were found.

    The first Danish commercial wind turbines were installed in the late 1970s. Over the last 20 years the Danish wind turbine market has been relatively stable concerning annual installations, and the wind turbine technology has been able to develop continuously. This gives a unique time track for technology analysts. The aim of this paper is to extract reliable information on this time track from existing archives and statistics. Seven generations of wind turbine technology have been identified mainly based on `characteristic` rotor diameters. The technological development of each generation is described using indicators such as: market share in Denmark, generator size, rotor diameter, hub height, electricity production and productivity. Economical indicators comprise: costs of turbine and standard foundation. (au)

    The Proteomics Standards Initiative (PSI) of the Human Proteome Organization (HUPO) has now been developing and promoting open community standards and software tools in the field of proteomics for 15 years. Under the guidance of the chair, cochairs, and other leadership positions, the PSI working groups are tasked with the development and maintenance of community standards via special workshops and ongoing work. Among the existing ratified standards, the PSI working groups continue to update PSI-MI XML, MITAB, mzML, mzIdentML, mzQuantML, mzTab, and the MIAPE (Minimum Information About a Proteomics Experiment) guidelines with the advance of new technologies and techniques. Furthermore, new standards are currently either in the final stages of completion (proBed and proBAM for proteogenomics results as well as PEFF) or in early stages of design (a spectral library standard format, a universal spectrum identifier, the qcML quality control format, and the Protein Expression Interface (PROXI) web services Application Programming Interface). In this work we review the current status of all of these aspects of the PSI, describe synergies with other efforts such as the ProteomeXchange Consortium, the Human Proteome Project, and the metabolomics community, and provide a look at future directions of the PSI.

    This report, Vol. II, presents a discussion of the operations of the ten EES pilot state programs during the period from October 1, 1977 through September 30, 1979. Each of the ten pilot states - Alabama, Connecticut, Michigan, New Mexico, Pennsylvania, Tennessee, Texas, Washington, Wisconsin, and Wyoming - received a grant of approximately $1.1 million to develop and implement an 18-month program beginning on October 1, 1977. In September 1978, each State received an additional $370,000 for service-delivery programs for the extension of the pilot program, April 1979 through September 1979. A case-study description of the operations of the pilot program in each State is provided here, with special attention given to the two programs selected in each State for more-detailed study and survey research. Although the thrust of this volume is descriptive, some survey data and analyses are presented for the emphasis programs. Two telephone surveys of clients and a non-client sample were conducted, one at the end of the first year of the pilot program (October 1977 - September 1978) and one at the end of the second year (October 1978 - September 1979).

    As the number of nuclear installations undergoing decontamination and decommissioning (D ampersand D) increases, current radioactive waste storage space is consumed and establishment of new waste storage areas becomes increasingly difficult. The problem of handling and storing radioactive scrap metal (RSM) gains increasing importance in the DOE Environmental Restoration and Waste Management Program. To alleviate present and future waste storage problems, Westinghouse Idaho Nuclear Company (WINCO) is managing a program for the recycling of RSM for beneficial use within the DOE complex. As part of that effort, Montana Tech has been awarded a contract to help optimize melting and refining technologies for the recycling of stainless steel RSM. The scope of the Montana Tech program includes a literature survey, a decontaminating slag design study, small scale melting studies to determine optimum slag compositions for removal of radioactive contaminant surrogates, analysis of preferred melting techniques, and coordination of pilot scale melting demonstrations (100-500 lbs) to be conducted at selected commercial facilities. This program will identify methods that can be used to recycle stainless steel RSM which will be used to fabricate high and low level waste canisters for the Idaho Waste Immobilization Facility. This report summarizes the results of an extensive literature review and the first year's progress on slag design, small-scale melt refining of surrogate-containing stainless steel (presently only a three month effort), and pilot-scale preparation of surrogate master ingots

    Large ultramafic areas exist in Albania, which could be suitable for phytomining with native Alyssum murale. We undertook a five-year field experiment on an ultramafic Vertisol, aimed at optimizing a low-cost Ni-phytoextraction crop of A. murale which is adapted to the Balkans. The following aspects were studied on 18-m2 plots in natural conditions: the effect of (i) plant phenology and element distribution, (ii) plant nutrition and fertilization, (iii) plant cover and weed control and (iv), planting technique (natural cover vs. sown crop). The optimal harvest time was set at the mid-flowering stage when Ni concentration and biomass yield were highest. The application of N, P, and K fertilizers, and especially a split 100-kg ha(-1) N application, increased the density of A. murale against all other species. It significantly increased shoot yield, without reducing Ni concentration. In natural stands, the control of graminaceous weeds required the use of an anti-monocots herbicide. However, after the optimization of fertilization and harvest time, weed control procured little benefit. Finally, cropping sown A. murale was more efficient than enhancing native stands and gave higher biomass and phytoextraction yields; biomass yields progressively improved from 0.3 to 9.0 t ha(-1) and phytoextracted Ni increased from 1.7 to 105 kg ha(-1).

    Since the beginning of the cholera epidemic in Haiti 5 years ago, the prevalence of this deadly water-borne disease has fallen far below the initial rates registered during its explosive outset. However, cholera continues to cause extensive suffering and needless deaths across the country, particularly among the poor. The urgent need to eliminate transmission of cholera persists: compared to the same period in 2014, the first 4 months of 2015 saw three times the number of cholera cases. Drawing upon epidemiology, clinical work (and clinical knowledge), policy, ecology, and political economy, and informed by ethnographic data collected in a rural area of Haiti called Bocozel, this paper evaluates the progress of the nation's 10-year Plan for the Elimination of Cholera. Bocozel is a rice-producing region where most people live in extreme poverty. The irrigation network is decrepit, the land is prone to environmental shocks, fertilizer is not affordable, and the government's capacity to assist farmers is undermined by resource constraints. When peasants do have rice to sell, the price of domestically grown rice is twice that of US-imported rice. Canal water is not only used to irrigate thousands of acres of rice paddies and sustain livestock, but also to bathe, wash, and play, while water from wells, hand pumps, and the river is used for drinking, cooking, and bathing. Only one out of the three government-sponsored water treatment stations in the research area is still functional and utilized by those who can afford it. Latrines are scarce and often shared by up to 30 people; open defecation remains common. Structural vulnerabilities cut across all sectors - not just water, sanitation, health care, and education, but agriculture, environment, (global and local) commerce, transportation, and governance as well. These are among the hidden sicknesses that impede Haiti and its partners' capacity to eliminate cholera.

  9. 50 Years of Independence: Reflections on the Role of Publishing and Progressive African Intellectuals

    2014-01-01

    Full Text Available In this contribution, the role of progressive African intellectuals fifty years after independence in the context of African postcolonial, political and socio-economic conditions is examined. African intellectuals have been marginalized by the African state, and progressive intellectuals have been disunited in their struggle for relevance. The possibilities for African intellectual autonomy and international solidarity are shown through a recollection of the flourishing intellectual environment and local publishing output of post-independence Tanzania. The end of that era and the demise of publishing, including in African languages, has negatively impacted African economic and intellectual emancipation and can only be addressed by international solidarity among progressive intellectuals.

    The data on children with diagnosis of idiopathic transverse myelitis (ITM) was searched to find the pattern of myelitis in Oman. A retrospective study was carried out from January1995 to December 2014. Electronic medical records and patient medical files were seen to get the complete data of the children with ITM. This work was carried out at Sultan Qaboos University hospital, Muscat, Oman. The ethical committee of the hospital had approved the study. The diagnosis was based on the established criteria. Other causes of myelopathy were excluded. 19 children with idiopathic transverse myelitis were found. There were 18 out of 19 (94.6%) children with longitudinal extensive transverse myelitis (LETM). Longitudinal transverse extensive myelitis is the most common form of ITM in Oman.

    The last two years have been marked by real progress in networking in HEP. Home-made developments, studies and plans have given way to the use of real networks involving hundreds of HEP and other computers and based on externally produced software and hardware. Within the last year, the first generation of industrial software products following some of the international standards for networking have become available. Related developments are taking place in networking for on-line systems and indeed the LEP experiments are distinguished by their heavy and crucial reliance on both local and wide-area networks. This paper describes the progress made at CERN since the last two years and looks at perspectives for the future. (orig.)

    This is the case of a 42-year-old female who presented with transient dizziness. Her symptoms and signs progressed to include dysarthria, ataxia and cognitive decline over 2 years, such that she was unable to care for herself. She died 4 years after first presentation without a diagnosis. Investigations revealed a normochromic normocytic anaemia. Cerebrospinal fluid was normal. Serial computed tomography brain showed a wedge-shaped frontal infarct but no progressive changes. Examination at autopsy showed discoloration of the gray and white matter of the brain and spinal cord.Microscopy of leptomeningeal and parenchymal vessels showed they were filled with atypical B lymphocytes confined to the intravascular space with multiple infarcts in the brain, cerebellum and spinal cord. A diagnosis of intravascular B cell lymphoma was made and is discussed.

    This study aimed at evaluating whether ultrasound monitoring of moderate asymptomatic carotid stenosis may help in identifying subjects at high risk for vascular events. We included 523 subjects with unilateral asymptomatic carotid stenosis of 50% to 69%. Follow-up carotid ultrasound was performed within 12 months from inclusion to detect the frequency and degree of stenosis progression. Subjects were prospectively evaluated for a median period of 42 months (interquartile range, 38-45) after a second ultrasound evaluation. Outcome measures were any stroke and transient ischemic attack, myocardial infarction, and death. Carotid stenosis progression was associated with the occurrence of vascular events (hazard ratio, 21.57; 95% confidence interval, 11.81-39.39; P<0.001). During follow-up, 96.7% of subjects without progressive carotid stenosis remained free from vascular events. Among patients with progressive stenosis, 53.7% experienced a vascular event and 27.1% experienced an ipsilateral stroke. One-year moderate asymptomatic carotid stenosis progression is related to higher risk of vascular events, including ipsilateral stroke.

  8. Novel AAV-based rat model of forebrain synucleinopathy shows extensive pathologies and progressive loss of cholinergic interneurons.

    Full Text Available Synucleinopathies, characterized by intracellular aggregation of α-synuclein protein, share a number of features in pathology and disease progression. However, the vulnerable cell population differs significantly between the disorders, despite being caused by the same protein. While the vulnerability of dopamine cells in the substantia nigra to α-synuclein over-expression, and its link to Parkinson's disease, is well studied, animal models recapitulating the cortical degeneration in dementia with Lewy-bodies (DLB are much less mature. The aim of this study was to develop a first rat model of widespread progressive synucleinopathy throughout the forebrain using adeno-associated viral (AAV vector mediated gene delivery. Through bilateral injection of an AAV6 vector expressing human wild-type α-synuclein into the forebrain of neonatal rats, we were able to achieve widespread, robust α-synuclein expression with preferential expression in the frontal cortex. These animals displayed a progressive emergence of hyper-locomotion and dysregulated response to the dopaminergic agonist apomorphine. The animals receiving the α-synuclein vector displayed significant α-synuclein pathology including intra-cellular inclusion bodies, axonal pathology and elevated levels of phosphorylated α-synuclein, accompanied by significant loss of cortical neurons and a progressive reduction in both cortical and striatal ChAT positive interneurons. Furthermore, we found evidence of α-synuclein sequestered by IBA-1 positive microglia, which was coupled with a distinct change in morphology. In areas of most prominent pathology, the total α-synuclein levels were increased to, on average, two-fold, which is similar to the levels observed in patients with SNCA gene triplication, associated with cortical Lewy body pathology. This study provides a novel rat model of progressive cortical synucleinopathy, showing for the first time that cholinergic interneurons are vulnerable

    To evaluate myopia prevalence, myopia progression, and various potential myopia risk factors in third-year law students. Cross-sectional study and survey. One hundred seventy-nine third-year law students at the University of Pennsylvania. We administered a questionnaire to assess the prevalence of myopia, myopia progression, and risk factors, including near work, family history, and daily light/dark exposure. We conducted a screening eye examination to ascertain myopia status. Myopia was defined as the mean spherical equivalent of the two eyes of school. (1) prevalence of myopia, (2) progression of myopia. Seventy-nine percent of the class participated (n = 179, two were excluded for amblyopia leaving 177 students). Fifty-eight percent were male, 75% were Caucasian, and the mean age was 27 years. Seventy-nine percent reported parental myopia. The mean amount of near work was 7.4 hours/day; mean sleep was 7.9 hours/day; mean darkness was 5.3 hours/day. Sixty-six percent of the students were myopic. Of 96 participants myopic before law school, myopia increased in 83 (86%) during law school. Among 75 students not myopic at the beginning of law school, 14 (19%) became myopic. The onset of myopia could not be determined for 6 patients. There were trends for higher myopia prevalence among those with a parental myopia history (P = 0.14) and for increased myopia progression among those reporting more daily near work (P = 0.18). Students with 5.6 hours of darkness per day (95% vs. 80%, P = 0.07). To account for possible confounding effects of risk factors with myopia progression, logistic regression with categorization of the continuous exposure variables (hours of near work, sleep, and darkness) above or below median values weakened the near work association (odds ratio 1.8, 95% confidence interval 0.5-6.7, P = 0.35) but continued to identify darkness association with daily hours of darkness (odds ratio 4.8, 95% confidence interval 1.0 >/= 23.3, P students with myopia

    aimed to examine the relation between fat mass (FM) or fat-free mass (FFM) tissues at birth and their accretion during early infancy, and later developmental progression. In a birth cohort from Ethiopia, 455 children who have BC measurement at birth and 416 who have standardised rate of BC growth during...... variables was examined using linear-mixed regression model. The finding revealed that FFM at birth was positively associated with global developmental progression from 1 to 5 years (β=1·75; 95 % CI 0·11, 3·39) and from 4 to 5 years (β=1·34; 95 % CI 0·23, 2·44) in the adjusted model. Furthermore, the rate...... of postnatal FFM tissue accretion was positively associated with development at 1 year of age (β=0·50; 95 % CI 0·01, 0·99). Neither fetal nor postnatal FM showed a significant association. In conclusion, fetal, rather than postnatal, FFM tissue accretion was associated with developmental progression...

    Full Text Available Objective:Extensively drug-resistant tuberculosis (XDR-TB strains were emerged when multidrug-resistant TB (MDR- TB was inadequately treated. Inadequate treatment of MDR-TB cases may result in additional resistance especially non-XDR-TB and then XDR-TB. The aim of this study was to know the prevalence, resistance patterns and trends of the XDR-TB strains among the MDR-TB at a tertiary care hospital in Lucknow, India Methods: A total of 430 Mycobacterium isolates were underwent NAP test and TB MPT64 Ag test for the identification of Mycobacterium tuberculosis complex (MTBC. Drug-susceptibility test (DST was performed over MTBC for the first line drugs by 1% proportion method (Bactec and for the second-line drugs by 1% proportion method (Lowenstein- Jensen media. The XDR-TB status was further confirmed by line probe assay (GenoType® MTBDRsl assay. Results: Among the 430 isolates of mycobacterium, 365 (84.9% were MTBC and 139 (38.1% were MDR-TB respectively. Further 97 MDR-TB from “highly suspected drug resistant-TB (DR-TB” cases among MDR-TB were tested with second line drugs in which 15 (15.5% XDR-TB and 82 (84.5% were non-XDR-TB. Regarding XDR-TB status, using the 1% proportion method a 100% agreement was seen with the GenoType® MTBDRsl assay. Resistance patterns of XDR-TB were as; 10/15 (66.7% as isoniazid + rifampicin + ciprofloxacin + amikacin resistance and 5/15 (33.3% as isoniazid + rifampicin + ciprofloxacin + amikacin + kanamycin resistance. Conclusion:The prevalence of XDR-TB was 15.5% among MDR-TB. Hence laboratory testing of “highly suspected drug resistant-TB” isolates should be done for both first and second line drugs simultaneously especially in developing countries.J Microbiol Infect Dis 2013;3(4: 169-175

    The primary purpose of this study was to determine whether progressive tinnitus management Level 3 skills education workshops conducted at the Bay Pines and Boston Veterans Affairs hospitals result in consistent use of the presented tinnitus management strategies by patients 1-5 years after completing the workshops. In fiscal year (FY) 2015, the tinnitus workshop follow-up form was mailed to all veterans who completed the Level 3 workshops between FY 2010 and FY 2014. Data were compiled to determine which, if any, of the skills taught in the workshops were being used 1-5 years after completion of the workshops and the impact on quality-of-life indicators. All self-management skills were being utilized up to 5 years postcompletion; therapeutic sound was utilized the most. The majority of patients reported an improved ability to manage reactions to tinnitus and improved quality-of-life indicators. Over 90% of patients from both sites recommended the program to others with tinnitus. The self-management skills taught in the progressive tinnitus management Level 3 workshops are sustained over time even when limited resources prevent the full complement of workshops or the involvement of mental health services. The workshops can also be successfully implemented through remote delivery via videoconferencing (telehealth). https://doi.org/10.23641/asha.5370883.

    The Meek technique of skin expansion is useful for covering a large open wound with a small piece of skin graft, but requires a carefully followed protocol. Over the past 5 years, a skin graft expansion technique following the Meek principle was used to treat 37 individuals who had sustained third degree burns involving more than 40% of the body surface. A scheme was devised whereby the body was divided into six areas, in order to clarify the optimal order of wound debridements and skin grafting procedures as well as the regimen of aftercare. The mean body surface involvement was 72.9% and the mean area of third degree burns was 41%. The average number of operations required was 1.84. There were four deaths among in this group of patients. The Meek technique of skin expansion and the suggested protocol are together efficient and effective in covering an open wound, particularly where there is a paucity of skin graft donor sites.

    We present our 20 years experience treating patients with vena cava extension in whom an extracorporeal circulation, hypothermia, cardio circulatory arrest (ECC-H-CCA) in order to perform, together with a tumoral resection, a thrombus resection. From 1985 to 2005 a total of 28 retroperitoneal tumor were treated: 25 renal cancers, a Wilms tumor, a paratesticular rabdomiosarcoma, and a pheocromocitoma. All of them had an extension by means of thrombus above the suprahepatics veins. All of them were treated by means of ECC-H-CCA for thrombus extraction. A descriptive study of the serie is performed as well as a Kaplan Meyer survival study. Surgical complications were present within 10 patients (35%), with a surgical mortality of two patients (7%): one intra-operatively because a massive embolism of the lungs and the other because of a lung embolism on the 4th post-operative day. Global actuarial survival was 29.1+/-10% at three years and 17.5+/-8% at five years. Analyzing only who do not have metastatic lesions, nor lymph nodes at diagnosis their three year survival was 50.9+/-16.3% and 32.2+/-16% at five years. Mean while those who have any metastatic lesion at diagnosis their three and five years survival was 20.8+/-12% and 10.4+/-9% respectively. The employ of surgical techniques with ECC-H-CCA with in oncological pathology associated with vena cava thrombus is justified and its employment does not worsen the survival; it is indicated because its results, allowing a complete tumoral resection in a safe and reproducible fashion.

    Following the cancellation of the 2001 International RERTR Meeting, which had been planned to occur in Bali, Indonesia, this paper describes the progress achieved by the Reduced Enrichment for Research and Test Reactors (RERTR) Program in collaboration with its many international partners during the years 2001 and 2002, and discusses the main activities planned for the year 2003. The past two years have been characterized by very important achievements of the RERTR program, but these technical achievements have been overshadowed by the terrible events of September 11, 2001. Those events have caused the U.S. Government to reevaluate the importance and urgency of the RERTR program goals. A recommendation made at the highest levels of the government calls for an immediate acceleration of the program activities, with the goal of converting all the world's research reactors to low-enriched fuel at the earliest possible time, and including both Soviet-designed and United States-designed research reactors

    The Movement Disorder Society Unified Parkinson Disease Rating Scale (MDS-UDPRS) is a commonly used tool to measure Parkinson disease (PD) progression. Longitudinal changes in MDS-UPDRS scores in de novo PD have not been established. Determine progression rates of MDS-UPDRS scores in de novo PD. 362 participants from the Parkinson's Progression Markers Initiative, a multicenter longitudinal cohort study of de novo PD, were included. Longitudinal progression of MDS-UPDRS total and subscale scores were modeled using mixed model regression. MDS-UPDRS scores increased in a linear fashion over five years in de novo PD. MDS-UPDRS total score increased an estimated 4.0 points/year, Part I 0.25 points/year, Part II 1.0 points/year, and Part III 2.4 points/year. The expected average progression of MDS-UPDRS scores in de novo PD from this study can assist in clinical monitoring and provide comparative data for detection of disease modification in treatment trials.

    The psychology of extinction has been studied for decades. Approximately 10 years ago, however, there began a concerted effort to understand the neural circuits of extinction of fear conditioning, in both animals and humans. Progress during this period has been facilitated by an unusual degree of coordination between rodent and human researchers examining fear extinction. This successful research program could serve as a model for translational research in other areas of behavioral neuroscience. Here we review the major advances and highlight new approaches to understanding and exploiting fear extinction. PMID:22129456

    Reston, E G; Bueno, Rpr; Closs, L Q; Zettermann, J

    Internal bleaching in endodontically treated teeth requires care and protection to prevent harm to the periodontal ligament due to peroxide and may result in external root resorption. There is a myriad of treatment options when this occurs, such as monitoring, extraction, and subsequent rehabilitation with implants or fixed prosthodontics. In some cases, such as the one described here, a conservative attempt to maintain the tooth as a single structure can be made by sealing the resorptive defect. In the present case, we show a multidisciplinary approach where orthodontics, periodontics, and restorative dentistry were involved in treating the maxillary right central incisor (#8) of a 65-year-old patient with extensive cervical resorption, whose chief complaint was esthetics. The proposed treatment was extrusion of the tooth followed by curettage and restoration of the defect with glass ionomer cement. The patient has been followed for 15 years with no signs of recurrence, maintenance of periodontal health, and patient satisfaction with the esthetic outcome.

    Full Text Available ABSTRACT Purpose: We aimed to report and analyze topographic and refractive outcomes following corneal collagen crosslinking (CXL in patients with progressive keratoconus (KC. Methods: We performed a retrospective, analytical, and observational study of 100 eyes from 74 progressive KC patients who underwent CXL at the Eye Hospital of Paraná. Keratometric values were analyzed preoperatively as well as 3 and 12 months postoperatively. Results: For a total of 100 eyes, 68 belonged to male patients. The mean age of our study population was 19.9 ± 5.61 years. The average visual acuity and topographic parameters overall were stable after 1 year (p<0.05. After 3 months, steepest keratometry reading (K2 and maximum keratometry (Kmax were significantly decreased (p<0.05. Regarding topographic astigmatism (dK, there was no significant difference between the 3-month and 12-month follow-ups. When we made comparisons between genders following CXL, there were no significant differences related to the changes in Kmax, K2, and spectacle-corrected distance visual acuity (SCDVA. Conclusions: CXL promoted stabilization or improvement of keratometric values and visual acuity. We found that keratoconus apex stability may be achieved 3 months after the procedure. There was no significant difference in keratometric and refractive values measured between male and female patients.

    History  A 30-year-old man presented with a history of progressive muscle weakness, difficulty in concentrating, and a slender habitus since early childhood. Marfan syndrome was suspected since the age of 14. Examinations  13 years later he was examined by Marfan experts and by genetic testing and Marfan syndrome could not be confirmed. Further neurological examination revealed the suspected diagnosis of myotonic dystrophy type 1, which was confirmed by genetic testing. Treatment and course  Similar to Marfan syndrome, myotonic dystrophy is a multisystemic disorder with the risk of cardiac arrythmias. It is necessary to provide an interdisciplinary care by neurologists, internists, ophthalmologists, speech therapists, and physiotherapists. Conclusion  It is not enough to take the habitus as the principle sign to diagnose Marfan syndrome. Furthermore, it is essential to consider symptoms that are not typical for Marfan syndrome, such as cognitive deficiencies or progressive paresis. © Georg Thieme Verlag KG Stuttgart · New York.

    The German Journal of Gastroenterology celebrates its fifties anniversary in 2013. Over half a century original studies, reviews and guidelines covering the topics of acute and chronic pancreatitis as well as pancreatic cancer have assumed a prominent role on its pages. Already in the first edition of the Journal Haemmerli and Hefti have summarized the Zurich experience with chronic pancreatitis and provided a detailed state-of-the-art review for the year 1963. 50 years later the current guidelines of the German Society of Digestive and Metabolic Diseases (DGVS) have been published in the same Journal and allow to summarize the scientific progress over this period. Back then chronic pancreatitis was regarded as a rare disorder (tenfold less common than e. g. acute pancreatitis or pancreatic cancer). This misconception had little to do with actual prevalence but with highly insensitive diagnostic tests, particularly in the area of diagnostic imaging. While pathogenetic factors for chronic pancreatitis, including a possible genetic disposition, were largely known in 1963, our understanding of their cellular mechanisms has very much improved. The greatest progress in diagnostic options was achieved by the introduction of novel imaging techniques such as ultrasound and endoscopic ultrasound, ERCP, CT and MRCP. In terms of therapy the notion that a blockage of pancreatitic secretion is an effective pharmacological option has been abandoned and endoscopic intervention and surgical treatment have been newly developed as alternatives. © Georg Thieme Verlag KG Stuttgart · New York.

    In 2006, the Government of Canada adopted a new long-term strategy to deal with the nuclear legacy liabilities and initiated a five-year start-up phase. The objective is to safely and cost-effectively reduce these liabilities, and associated risks, based on sound waste management and environmental principles in the best interests of Canadians. AECL's Whiteshell Laboratories is part of the long-term strategy and decommissioning activities are underway. Several redundant non-nuclear buildings have been removed/decommissioned, and redundant nuclear facilities (hot cell facilities, radiochemical laboratories) are being decontaminated and prepared for demolition. This paper describes the progress in the first five-year funding period (2006 April to 2011 March). (author)

    2018-05-01

    Full Text Available The discovery of induced pluripotent stem cells (iPSCs by Shinya Yamanaka in 2006 was heralded as a major breakthrough of the decade in stem cell research. The ability to reprogram human somatic cells to a pluripotent embryonic stem cell-like state through the ectopic expression of a combination of embryonic transcription factors was greeted with great excitement by scientists and bioethicists. The reprogramming technology offers the opportunity to generate patient-specific stem cells for modeling human diseases, drug development and screening, and individualized regenerative cell therapy. However, fundamental questions have been raised regarding the molecular mechanism of iPSCs generation, a process still poorly understood by scientists. The efficiency of reprogramming of iPSCs remains low due to the effect of various barriers to reprogramming. There is also the risk of chromosomal instability and oncogenic transformation associated with the use of viral vectors, such as retrovirus and lentivirus, which deliver the reprogramming transcription factors by integration in the host cell genome. These challenges can hinder the therapeutic prospects and promise of iPSCs and their clinical applications. Consequently, extensive studies have been done to elucidate the molecular mechanism of reprogramming and novel strategies have been identified which help to improve the efficiency of reprogramming methods and overcome the safety concerns linked with iPSC generation. Distinct barriers and enhancers of reprogramming have been elucidated, and non-integrating reprogramming methods have been reported. Here, we summarize the progress and the recent advances that have been made over the last 10 years in the iPSC field, with emphasis on the molecular mechanism of reprogramming, strategies to improve the efficiency of reprogramming, characteristics and limitations of iPSCs, and the progress made in the applications of iPSCs in the field of disease modelling

    The discovery of induced pluripotent stem cells (iPSCs) by Shinya Yamanaka in 2006 was heralded as a major breakthrough of the decade in stem cell research. The ability to reprogram human somatic cells to a pluripotent embryonic stem cell-like state through the ectopic expression of a combination of embryonic transcription factors was greeted with great excitement by scientists and bioethicists. The reprogramming technology offers the opportunity to generate patient-specific stem cells for modeling human diseases, drug development and screening, and individualized regenerative cell therapy. However, fundamental questions have been raised regarding the molecular mechanism of iPSCs generation, a process still poorly understood by scientists. The efficiency of reprogramming of iPSCs remains low due to the effect of various barriers to reprogramming. There is also the risk of chromosomal instability and oncogenic transformation associated with the use of viral vectors, such as retrovirus and lentivirus, which deliver the reprogramming transcription factors by integration in the host cell genome. These challenges can hinder the therapeutic prospects and promise of iPSCs and their clinical applications. Consequently, extensive studies have been done to elucidate the molecular mechanism of reprogramming and novel strategies have been identified which help to improve the efficiency of reprogramming methods and overcome the safety concerns linked with iPSC generation. Distinct barriers and enhancers of reprogramming have been elucidated, and non-integrating reprogramming methods have been reported. Here, we summarize the progress and the recent advances that have been made over the last 10 years in the iPSC field, with emphasis on the molecular mechanism of reprogramming, strategies to improve the efficiency of reprogramming, characteristics and limitations of iPSCs, and the progress made in the applications of iPSCs in the field of disease modelling, drug discovery and

    Full Text Available Abstract Background Cardiomyopathy is a leading cause of morbidity and mortality in boys with Duchenne muscular dystrophy (DMD. We recently showed in a 12-month double-blind randomized controlled trial that adding eplerenone to background medical therapy was cardioprotective in this population. The objective of this study was to evaluate the safety and efficacy of longer-term eplerenone therapy in boys with DMD. Results Eleven subjects (phase 1 baseline median [range] age: 13 [7 – 25] years from the original 12-month trial at a single participating center were enrolled. Importantly, those who entered the extension study who had been on eplerenone previously were significantly older than those who had originally been on placebo (median age 10.5 vs. 18.0 years, p = 0.045. During an additional 24-month open-label extension study, all boys received eplerenone 25 mg orally once daily to treat preclinical DMD cardiomyopathy, defined as evident myocardial damage by late gadolinium enhancement cardiac magnetic resonance (LGE with preserved ejection fraction (EF. The threshold for potassium level, the primary safety measure, was not exceeded in any non-hemolyzed blood sample. Over 24 months, left ventricular (LV systolic strain, a more sensitive marker whose more negative values indicate greater contractility significantly improved (median change -4.4%, IQR -5.8 to -0.9% in younger subjects whereas older subjects’ strain remained stable without significant worsening or improvement (median change 0.2%, IQR -1.1 to 4.3%. EF and extent of myocardial damage by LGE remained stable in both groups over 2 years. Conclusions Eplerenone offers effective and safe cardioprotection for boys with DMD, particularly when started at a younger age. Eplerenone is a useful clinical therapeutic option, particularly if treatment is initiated earlier in life when cardiac damage is minimal.

    Full Text Available Background Progress testing is a method of assessing longitudinal progress of students using a single best answer format pitched at the standard of a newly graduated doctor. Aim To evaluate the results of the first year of summative progress testing at the University of Auckland for Years 2 and 4 in 2013. SUBJECTS: Two cohorts of medical students from Years 2 and 4 of the Medical Program. Methods A survey was administered to all involved students. Open text feedback was also sought. Psychometric data were collected on test performance, and indices of reliability and validity were calculated. Results The three tests showed increased mean scores over time. Reliability of the assessments was uniformly high. There was good concurrent validity. Students believe that progress testing assists in integrating science with clinical knowledge and improve learning. Year 4 students reported improved knowledge retention and deeper understanding. Conclusion Progress testing has been successfully introduced into the Faculty for two separate year cohorts and results have met expectations. Other year cohorts will be added incrementally. Recommendation Key success factors for introducing progress testing are partnership with an experienced university, multiple and iterative briefings with staff and students as well as demonstrating the usefulness of progress testing by providing students with detailed feedback on performance.

    Identifying extra spinal causes of a lumbar radiculopathy or polyneuropathy can be a tricky diagnosis challenge, especially in children. Among them, traumatic or iatrogenic pseudoaneurysms of iliac arteries have been seldom reported, in adults' series. The authors report an unusual case of progressive paralyzing left sciatica and lumbar plexopathy in a 12 years old boy, 12 months after a pelvic osteotomy for bilateral hip luxation secondary to osteochondritis dissecans. Spine MRI and pelvic CT angiography revealed a giant internal iliac artery pseudoaneurysm, enclosed in a chronic hematoma. The patient was successfully treated with endovascular coil embolization, and subsequent surgical hematoma evacuation. However, three months after treatment, neurological recovery was incomplete. This case highlights the importance of a rapid and extensive diagnosis work up of all causes of lower limb radiculopathies in children, including pelvic arteries lesions especially after pelvic surgery to avoid therapeutic delays that may jeopardize the chances of neurological recovery.

    Since 1968 we have employed supervoltage orbital radiation as treatment for severe progressive Graves' ophthalmopathy. A numerical ophthalmic index was used to asess pre- and post-treatment serverity. In the past 20 years we have treated 311 patients of whom 275 have been followed for {le} 1 year or until any eye surgery was performed. An orbital radiation dosage of 2000 rads in 2 weeks was used for the majority of patients (Series I and III). Series II patients received an orbital dose of 3000 rads in 3 weeks. Demographic differences were observed between these series, thus mandating presentation of the results of each separately. Analyses excluded any result achieved by any post-radiation surgical procedure on the eyes. Post-theraphy worsening of ophtalmopathy occurred in only 29 of 1025 observations. Improvement or complete resolution was observed within each category of eye involvement, but lack of favorable response was also recorded in significant numbers. Improvement in proptosis occurred with the lowest frequency and magnitude. About 30% of the patients required eye muscle surgery to correct residual diplopia. Analysis of the data by step-wise linear regression analysis enabled us a. to derive formulae predicting the problable response to radiation therapy according to sign and severity, and b. identify parameters which diminished the likelihood or the extent of a favorable response. The latter included male sex, never thyrotoxic, age greater than 60 years, and requirement for concomitant treatment for hyperthyroidism. No long-term adverse reactions attributable to the radiotherapy have been observed. We conclude that supervoltage orbital radiotherapy, combined with later eye muscle surgery if necessary, is an effective treatment strategy for progressive Graves' ophthalmopathy. (author).

    The zircaloy special committee was organized in 1971 for the purpose of planning the trial use of two nuclear fuel assemblies for which Japan-made cladding tubes were to be used, for a BWR. Now, seven years later, these two fuel assemblies have completed their service life, and have been submitted to post-irradiation examination after cooling for a year. Zircaloy tubes have been produced by Sumitomo Metal Industries, Ltd., and Kobe Steel, Ltd., and more than ten years have elapsed since wholly Japan-made zircaloy cladding tubes were used for reloading fuel elements for the Japan Power Demonstration Reactor. In this report, the history, progress and significance of the works performed by the committee are summarized. The LWR fuel elements made in Japan have attained the highest performance in the world as the leak has been scarce, and the works of the committee is one of the pioneering activities in the development of LWR fuel technology. The situation for starting the committee, the activity of the committee during ten years, the significance and outcome of the committee activity are reported. (Kako, I.)

    Purpose To determine the rate of progression and optimal follow up time in patients with advanced stage retinitis pigmentosa (RP) comparing the use of fundus autofluorescence imaging and spectral domain optical coherence tomography. Design Retrospective analysis of progression rate. Methods Longitudinal imaging follow up in 71 patients with retinitis pigmentosa was studied using the main outcome measurements of hyperautofluoresent ring horizontal diameter and vertical diameter along with ellipsoid zone line width from spectral domain optical coherence tomography. Test-retest reliability and the rate of progression were calculated. The interaction between the progression rates was tested for sex, age, mode of inheritance, and baseline measurement size. Symmetry of left and right eye progression rate was also tested. Results Significant progression was observed in >75% of patients during the 2 year mean follow up. The mean annual progression rates of ellipsoid zone line, and hyperautofluorescent ring horizontal diameter and vertical diameter were 0.45° (4.9%), 0.51° (4.1%), and 0.42° (4.0%), respectively. The e llipsoid zone line width, and hyperautofluorescent ring horizontal diameter and vertical diameter had low test-retest variabilities of 8.9%, 9.5% and 9.6%, respectively. This study is the first to demonstrate asymmetrical structural progression rate between right and left eye, which was found in 19% of patients. The rate of progression was significantly slower as the disease approached the fovea, supporting the theory that RP progresses in an exponential fashion. No significant interaction between progression rate and patient age, sex, or mode of inheritance was observed. Conclusions Fundus autofluorescence and optical coherence tomography detect progression in patients with RP reliably and with strong correlation. These parameters may be useful alongside functional assessments as the outcome measurements for future therapeutic trials. Follow-up at 1 year

  17. Economic growth and health progress in England and Wales: 160 years of a changing relation.

    Tapia Granados, José A

    2012-03-01

    Using data for England and Wales during the years 1840-2000, a negative relation is found between economic growth--measured by the rate of growth of gross domestic product (GDP)--and health progress--as indexed by the annual increase in life expectancy at birth (LEB). That is, the lower is the rate of growth of the economy, the greater is the annual increase in LEB for both males and females. This effect is much stronger, however, in 1900-1950 than in 1950-2000, and is very weak in the 19th century. It appears basically at lag zero, though some short-lag effects of the same negative sign are found. In the other direction of causality, there are very small effects of the change in LEB on economic growth. These results add to an emerging consensus that in the context of long-term declining trends, mortality oscillates procyclically during the business cycle, declining faster in recessions. Therefore, LEB increases faster during recessions than during expansions. The investigation also shows how the relation between economic growth and health progress changed in England and Wales during the study period. No evidence of cointegration between income--as indexed by GDP or GDP per capita--and health--as indexed by LEB--is found. Copyright © 2012 Elsevier Ltd. All rights reserved.

    This Annual Progress Report describes the work performed and summarizes some of the key observations to date on the U.S. Nuclear Regulatory Commission’s project Assessment of Food Chain Pathway Parameters in Biosphere Models, which was established to assess and evaluate a number of key parameters used in the food-chain models used in performance assessments of radioactive waste disposal facilities. Section 2 of this report describes activities undertaken to collect samples of soils from three regions of the United States, the Southeast, Northwest, and Southwest, and perform analyses to characterize their physical and chemical properties. Section 3 summarizes information gathered regarding agricultural practices and common and unusual crops grown in each of these three areas. Section 4 describes progress in studying radionuclide uptake in several representative crops from the three soil types in controlled laboratory conditions. Section 5 describes a range of international coordination activities undertaken by Project staff in order to support the underlying data needs of the Project. Section 6 provides a very brief summary of the status of the GENII Version 2 computer program, which is a “client” of the types of data being generated by the Project, and for which the Project will be providing training to the US NRC staff in the coming Fiscal Year. Several appendices provide additional supporting information.

    Full Text Available The pathogenesis of disease progression in drug-refractory epilepsy is poorly understood. We report the case of a young woman with a four-year history of epilepsy that progressed rapidly as evidenced by the development of progressive focal cortical atrophy. She underwent biopsy that showed perinatal ischemia and a prominent inflammatory response, including T-cell infiltration and microglial activation. There was no consensus reached on the final diagnosis although the hypothesis of dual pathology (adult variant of Rasmussen's encephalitis and perinatal stroke was considered. The possible role of inflammation in the progression of epilepsy caused by a “static” lesion (perinatal stroke is discussed.

    Full Text Available BACKGROUND: Few studies have formally assessed whether treatment outcomes have improved substantially over the years for patients with extensive disease small-cell lung cancer (ED-SCLC enrolled in phase III trials. The objective of the current investigation was to determine the time trends in outcomes for the patients in those trials. METHODS AND FINDINGS: We searched for trials that were reported between January 1981 and August 2008. Phase III randomized controlled trials were eligible if they compared first-line, systemic chemotherapy for ED-SCLC. Data were evaluated by using a linear regression analysis. RESULTS: In total, 52 trials were identified that had been initiated between 1980 and 2006; these studies involved 10,262 patients with 110 chemotherapy arms. The number of randomized patients and the proportion of patients with good performance status (PS increased over time. Cisplatin-based regimens, especially cisplatin and etoposide (PE regimen, have increasingly been studied, whereas cyclophosphamide, doxorubicin, and vincristine-based regimens have been less investigated. Multiple regression analysis showed no significant improvement in survival over the years. Additionally, the use of a PE regimen did not affect survival, whereas the proportion of patients with good PS and the trial design of assigning prophylactic cranial irradiation were significantly associated with favorable outcome. CONCLUSIONS AND SIGNIFICANCE: The survival of patients with ED-SCLC enrolled in phase III trials did not improve significantly over the years, suggesting the need for further development of novel targets, newer agents, and comprehensive patient care.

    The steps that some major oil companies in Canada have taken to prepare their computers and automated equipment for the year 2000 (Y2K) are described. It is acknowledged that with 1700 retail service stations, over 300 wholesale operations, and 26 terminals, the extent of the problem is great. In addition some 38 upstream and 65 downstream applications have been identified as mission critical, not counting the 30 mission critical control systems in the upstream field operations and approximately the same number of operations in the downstream refinery. The good news is that remediation and testing is well underway nationally and the Calgary test laboratory will be commercially available in 1999. Getting management on-side, selling the positive aspects of Y2K, making good use of reputable consulting companies, keeping employees properly informed of problems and progress, are some of the key criteria in solving Y2K problems successfully

  2. Twenty Years of Progress on Global Ocean Tides: The Impact of Satellite Altimetry

    2012-01-01

    At the dawn of the era of high-precision altimetry, before the launch of TOPEX/Poseidon, ocean tides were properly viewed as a source of noise--tidal variations in ocean height would represent a very substantial fraction of what the altimeter measures, and would have to be accurately predicted and subtracted if altimetry were to achieve its potential for ocean and climate studies. But to the extent that the altimetry could be severely contaminated by tides, it also represented an unprecedented global-scale tidal data set. These new data, together with research stimulated by the need for accurate tidal corrections, led to a renaissance in tidal studies in the oceanographic community. In this paper we review contributions of altimetry to tidal science over the past 20 years, emphasizing recent progress. Mapping of tides has now been extended from the early focus on major constituents in the open ocean to include minor constituents, (e.g., long-period tides; non-linear tides in shelf waters, and in the open ocean), and into shallow and coastal waters. Global and spatially local estimates of tidal energy balance have been refined, and the role of internal tide conversion in dissipating barotropic tidal energy is now well established through modeling, altimetry, and in situ observations. However, energy budgets for internal tides, and the role of tidal dissipation in vertical ocean mixing remain controversial topics. Altimetry may contribute to resolving some of these important questions through improved mapping of low-mode internal tides. This area has advanced significantly in recent years, with several global maps now available, and progress on constraining temporally incoherent components. For the future, new applications of altimetry (e.g., in the coastal ocean, where barotropic tidal models remain inadequate), and new mission concepts (studies of the submesoscale with SWOT, which will require correction for internal tides) may bring us full circle, again pushing

    The paper is focussed on the progress which has been made over 40 years in the science, technology and application of NDT/NDE both during manufacture and in-service, from the perspective of the author and his background in the energy industries in the UK. New techniques not dreamt of 40 years ago and new technology such as personal computers, lasers and robotics which are now common-place in everyday life have transformed some aspects of NDT. But other aspects have remained unchanged, including the continued use of the more basic NDT methods and the challenges of recruitment, training, certification and motivation of personnel. There have been major changes in the world scene over 40 years including the globalization of trade, the emergence of new countries as industrial powers, and the ageing of safety critical infrastructure. These have impacted on NDT business and on the activities of the international NDT community (including ICNDT, the International Committee for NDT). The paper concludes by introducing the activities championed by ICNDT to promote the understanding of the importance of NDT, to support the development of NDT Societies around the world, to educate users on the correct use of personnel certification and to pursue the objective of global harmonisation and recognition of third party certification

    Ten years have elapsed since the birth of the National Laboratory for High Energy Physics. For the growth to the present status, the researchers concerned, the Science Council of Japan, the Ministry of Education, the National Diet and many enterprises, all contributed greatly. The proton synchrotron was completed as scheduled, and its performance largely exceeded the initial target. The results of the common utilization experiments started in 1977 have been obtained successively, and the applied research other than the field of elementary particles also has advanced along the right line steadily, such as booster utilization facility and radiated beam experiment facility. In this year, the construction of the Tristan project has been started, and the pet name ''KEK'' is internationally well known now. The 21st century is said to be the age of elementary particles, and the mission and responsibility put on the researchers concerned will be heavier. In this book, the progress of the KEK during ten years is reviewed, and many persons who took part in the establishment of the KEK contributed their memoirs. Also, the round-table talk held on this occasion, the history of each research group, the future plans, the results of researches and the related materials are described. (Kako, I.)

    Progress during the first year of this program has been noteworthy in both theoretical and experimental areas. Substantial improvements to the MIT CARM codes have been carried out, and the code has been successfully benchmarked against other codes, linear theory, and experimental work. CARM amplifier phase stability has been studied theoretically and found to be significantly better than that of free-electron lasers or relativistic klystrons, provided the device is properly designed. Both multimode simulations and particle-in-cell simulations have been carried out to study mode competition effects between convectively unstable and absolutely unstable modes. Improvement of the Pierce-Wiggler code for modeling the beam formation prior to the interaction region has been carried out. Experimental designs for a long-pulse, modulator-driven CARM amplifier experiment which will be carried out by the end of this fiscal year have been mostly completed. Designs for an induction-linac-driven CARM amplifier experiment, which will be carried out by the end of Year II of this program,, have also been performed. Finally, a CARM oscillator experiment is presently underway at our facility

    Following the cancellation of the 2001 International RERTR Meeting, which had been planned to occur in Bali, Indonesia, this paper describes the progress achieved by the Reduced Enrichment for Research and Test Reactors (RERTR) Program in collaboration with its many international partners during the years 2001 and 2002, and discusses the main activities planned for the year 2003. The past two years have been characterized by very important achievements of the RERTR program, but these technical achievements have been overshadowed by the terrible events of September 11, 2001. Those events have caused the U.S. Government to reevaluate the importance and urgency of the RERTR program goals. A recommendation made at the highest levels of the government calls for an immediate acceleration of the program activities, with the goal of converting all the world's research reactors to low-enriched fuel at the earliest possible time, and including both Soviet-designed and United States-designed research reactors. The RERTR program has prepared and submitted to the Department of Energy a plan and a schedule to achieve this goal. The plan makes full use of two very important technical developments that have occurred within the program during the past two years: - Excellent results have been obtained from the irradiation of miniplates containing monolithic LEU U-Mo fuel with uranium density of 15.6 g/cm 3 . If an economically viable manner of fabricating monolithic LEU U-Mo fuel elements is developed, and if the preliminary irradiation tests are confirmed, this fuel holds the promise of enabling LEU operation of all existing and future research reactors in combination with unprecedented performance. - The progress achieved within the Russian RERTR program, both for the traditional tube-type elements and for the new 'universal' LEU U-Mo pin-type elements, promises to enable soon the conversion of most Russian-designed research and test reactors. The plan is structured to achieve LEU

    To examine how cognitive deficits progress in the years following a stroke or transient ischaemic attack (TIA). A follow-up study, with neuropsychological and MRI assessments undertaken 3 years after baseline assessments made 3-6 months poststroke in 183 stroke/TIA patients and 97 healthy controls participating in the Sydney Stroke Study. Additional measures included cardiovascular risk factors and apolipoprotein E (APOE) genotype. Stroke/TIA patients had poorer cognitive function and more vascular risk factors than controls at baseline, but did not show greater decline in cognitive function over 3 years except for verbal memory. Patients with a subsequent stroke/TIA showed greater decline in global cognitive function and a number of domains. Rates of incident dementia were 5.9% per year in patients and 0.4% in controls. Both groups showed increased atrophy of the hippocampus, amygdala and whole brain, and an increase in white matter hyperintensities over 3 years; whole brain atrophy was greater in patients. Cognitive decline was greater in women and in those with smaller hippocampi at baseline. For patients without a subsequent stroke/TIA, those with smaller hippocampi or the APOE ε4 allele had greater global cognitive and verbal memory decline. In poststroke patients, cognitive decline was not greater than in comparison subjects, except for verbal memory, unless they had another stroke/TIA. However, dementia incidence was higher in patients, as might be expected from their poorer baseline cognitive functioning. Smaller hippocampi were associated with an increased risk of decline in memory, and APOE ε4 was a risk factor in those without a subsequent stroke/TIA. Published by the BMJ Publishing Group Limited.

    Since the beginning of the cholera epidemic in Haiti 5 years ago, the prevalence of this deadly water-borne disease has fallen far below the initial rates registered during its explosive outset. However, cholera continues to cause extensive suffering and needless deaths across the country, particularly among the poor. The urgent need to eliminate transmission of cholera persists: compared to the same period in 2014, the first 4 months of 2015 saw three times the number of cholera cases. Drawing upon epidemiology, clinical work (and clinical knowledge), policy, ecology, and political economy, and informed by ethnographic data collected in a rural area of Haiti called Bocozel, this paper evaluates the progress of the nation’s 10-year Plan for the Elimination of Cholera. Bocozel is a rice-producing region where most people live in extreme poverty. The irrigation network is decrepit, the land is prone to environmental shocks, fertilizer is not affordable, and the government’s capacity to assist farmers is undermined by resource constraints. When peasants do have rice to sell, the price of domestically grown rice is twice that of US-imported rice. Canal water is not only used to irrigate thousands of acres of rice paddies and sustain livestock, but also to bathe, wash, and play, while water from wells, hand pumps, and the river is used for drinking, cooking, and bathing. Only one out of the three government-sponsored water treatment stations in the research area is still functional and utilized by those who can afford it. Latrines are scarce and often shared by up to 30 people; open defecation remains common. Structural vulnerabilities cut across all sectors – not just water, sanitation, health care, and education, but agriculture, environment, (global and local) commerce, transportation, and governance as well. These are among the hidden sicknesses that impede Haiti and its partners’ capacity to eliminate cholera. PMID:27307774

    from that development - the establishment of the Nuclear Waste Management Organization, the study of options for the long-term management of nuclear fuel waste, the Government's decision on the options, the agreement on a funding formula for nuclear fuel waste management, and the launch of the NWMO's siting process. In this same period, we also have witnessed progress on a long-term waste management facility for low and intermediate-level radioactive waste in Ontario - including an agreement with the hosting community. In addition, there has been further advancement in the management of uranium tailing, notably the launch of cleanup efforts at the Gunnar mine in northern Saskatchewan. Finally, the federal government has established robust programs for the management of historic and legacy wastes across the country. In terms of historic wastes, the Port Hope Area Initiative has advanced to the point where critical decisions will be made in 2011 on the launch of the implementation phase of that Project and the Low-Level Radioactive Waste Management Office continues to manage historic wastes at other sites across the country. As for legacy wastes, decisions are expected prior to the end of 2010 on the continuation of the Nuclear Legacy Liabilities Program which addresses decommissioning and radioactive waste liabilities at AECL sites in Manitoba, Ontario, Quebec, and Nova Scotia. The coming years will see the further advancement of these initiatives, all which will face their own challenges. Nevertheless, there is generally a defined strategy or path and the appropriate elements are in place to achieve success. Despite these initiatives, there remain gaps in Canada's approach to radioactive waste management. In particular, while there has been progress on the management of low and intermediate-level radioactive waste in Ontario to address wastes from Ontario Power Generation's facilities, there is, as yet, no long-term management approach defined for

    Full Text Available The relationship between a supervisor and employee has a direct effect on the employee’s job satisfaction, work productivity, and efficiency. Understanding the interactions between Extension agents and County Extension Directors is critical to maintaining positive relationships and providing adequate support to Extension supervisors through professional development and training opportunities. This article examined the dyadic relationships between Extension agents and County Extension Directors in Florida. The majority of Florida Extension agents have high-quality relationship with their County Extension Directors. In addition, over half of relationships of five years or less are in the partner phase, suggesting new employees of the Florida Cooperative Extension Service progress through the leadership making process in a relatively short amount of time. UF/IFAS Extension Administration should provide increased leadership training for County Extension Directors to ensure all dyads progress through the leadership-making process to the partner phase, such as relationship building, and management and supervisory training.

    This paper describes the progress achieved by the Reduced Enrichment for Research and Test Reactors (RERTR) Program in collaboration with its many international partners during the year 2000 and discusses the main activities planned for the year 2001. The past year was held by important accomplishments and events for the RERTR program: Four additional shipments containing 503 spent fuel assemblies from foreign research reactors were accepted by the U.S. Altogether, 3,740 spent fuel assemblies from foreign research reactors have been received by the U.S. under the acceptance policy; Postirradiation examinations of three batches of microplates have continued to reveal excellent irradiation behavior of U-Mo dispersion fuels in a variety of compositions and irradiating conditions. Irradiation of two new batches of miniplates of greater sizes is in progress in the ATR to investigate the swelling behavior of these fuels under prototypic conditions. These materials hold the promise of achieving the program goal of developing LEU research reactor fuels with uranium densities in the 8-9 g /cm 3 range; Qualification of the U-Mo dispersion fuels is proceeding on schedule. Test fuel elements with uranium density of 6 g/cm 3 are being fabricated by BWXT and are scheduled to begin undergoing irradiation in the HFR-Petten in the spring of 2001, with a goal of qualifying this fuel by the end of 2003. U-Mo fuel with uranium density of 8-9 g/cm 3 is planned to be qualified by the end of 2005; Joint LEU conversion feasibility studies were completed for HFR-Petten and for SAFARI-1; Significant improvements were made in the design of LEU metal-foil annular targets that would allow efficient production of fission 99 Mo.

    Malaysia enacted the Renewable Energy Act in April 2011. One of its important components is the feed-in tariff (FiT) scheme—launched in December 2011. The scheme is managed and administered by the Sustainable Energy Development Authority (SEDA) of Malaysia. This paper analyses the impact of the FiT mechanism in Malaysia a year after its implementation; particularly on the installation and economical aspects. First, the history of the scheme is presented before summarising the application process for the scheme. Next, a detailed evaluation on the implication of the scheme is discussed. Some of the key findings from the analysis include: (i) the uptake for renewable energy installations has been extremely high, particularly for solar photovoltaic installation; (ii) the foreign and domestic direct investment related to renewable sectors have increased significantly; (iii) more ‘green’ jobs have been created, particularly in the manufacturing and installation sectors, and (iv) there are plans to include wind and thermal energy in the FiT scheme. It can be concluded that the FiT scheme in Malaysia has produced significant impact during the first year of its implementation. With a proper monitoring by SEDA and more awareness among the people, renewable energy will most likely flourish in Malaysia. - Highlights: • Malaysia launched the feed-in tariff (FiT) scheme in December 2011. • The one year progress is evaluated in terms of installation and economical aspects. • The uptake for renewable energy installations has been extremely high. • Investment related to renewable sectors has increased significantly. • More ‘green’ jobs have been created in the country

  18. Long-distance swimming by polar bears (Ursus maritimus) of the southern Beaufort Sea during years of extensive open water

    Science.gov (United States)

    2014-01-01

    Polar bears (Ursus maritimus Phipps, 1774) depend on sea ice for catching marine mammal prey. Recent sea-ice declines have been linked to reductions in body condition, survival, and population size. Reduced foraging opportunity is hypothesized to be the primary cause of sea-ice-linked declines, but the costs of travel through a deteriorated sea-ice environment also may be a factor. We used movement data from 52 adult female polar bears wearing Global Positioning System (GPS) collars, including some with dependent young, to document long-distance swimming (>50 km) by polar bears in the southern Beaufort and Chukchi seas. During 6 years (2004-2009), we identified 50 long-distance swims by 20 bears. Swim duration and distance ranged from 0.7 to 9.7 days (mean = 3.4 days) and 53.7 to 687.1 km (mean = 154.2 km), respectively. Frequency of swimming appeared to increase over the course of the study. We show that adult female polar bears and their cubs are capable of swimming long distances during periods when extensive areas of open water are present. However, long-distance swimming appears to have higher energetic demands than moving over sea ice. Our observations suggest long-distance swimming is a behavioral response to declining summer sea-ice conditions.

    To evaluate the progression of dental erosion in 13-14 year-olds after 4 years, and its association with lifestyle and oral health. 227 randomly selected 13-14 year-olds from a Public Dental Clinic, Örebro, Sweden, were investigated. A clinical examination was performed which included dental caries/gingival/plaque status, as well as grading of dental erosion at the tooth surface and participant levels in "marker teeth", including buccal/palatal surfaces of 6 maxillary anterior teeth (13-23), and occlusal surfaces of first molars. An interview and a questionnaire regarding drinking habits and other lifestyle factors were completed. All investigations were repeated at follow-up. The participants were divided into high and low progression erosion groups and logistic regression statistics were applied. 175 individuals participated at follow-up. Progression occurred in 35% of the 2566 tooth surfaces. 32% of the surfaces had deteriorated by one severity grade (n=51 individuals) and 3% by two grades (n=2 individuals). Boys showed more severe erosion than girls at the follow-up. Among the variables predicting greater progression, a lower severity of erosive wear at baseline had the highest OR (13.3), followed in descending order by a "retaining" drinking technique, more frequent intake of drinks between meals, low GBI and lesser sour milk intake, with reference to the baseline recording. Using these five variables, sensitivity and specificity were 87% and 67% respectively, for predicting progression of erosion. Progression of erosive lesions in Swedish adolescents aged 13-14 years followed up to age 17-18 years was common and related to certain lifestyle factors. In permanent teeth, dental erosion may develop early in life and its progression is common. Dental health workers should be made aware of this fact and regular screenings for erosion and recording of associated lifestyle factors should be performed. Copyright © 2016 Z.

    The TORUS collaboration derives its name from the research it focuses on, namely the Theory of Reactions for Unstable iSotopes. It is a Topical Collaboration in Nuclear Theory, and funded by the Nuclear Theory Division of the Office of Nuclear Physics in the Office of Science of the Department of Energy. The funding started on June 1, 2010, it will have been running for nine months by the date of submission of this Annual Continuation and Progress Report on March 1, 2011. The extent of funding was reduced from the original application, and now supports one postdoctoral researcher for the years 1 through 3. The collaboration brings together as Principal Investigators a large fraction of the nuclear reaction theorists currently active within the USA. The mission of the TORUS Topical Collaboration is to develop new methods that will advance nuclear reaction theory for unstable isotopes by using three-body techniques to improve direct-reaction calculations, and, by using a new partial-fusion theory, to integrate descriptions of direct and compound-nucleus reactions. This multi-institution collaborative effort is directly relevant to three areas of interest: the properties of nuclei far from stability; microscopic studies of nuclear input parameters for astrophysics, and microscopic nuclear reaction theory.

  3. Environmental restoration of uranium mines in Canada: Progress over 52 years

    In Canada, the technology for disposal of uranium mine wastes and reclamation of mines has evolved over a period of 52 years. Early practice involved dumping untreated wastes into the nearest depression or lake and leaving rock and infrastructure in place. Now, the practice is to deposit chemically-stabilized tailings, waste rock and building rubble into highly engineered waste management facilities or mine openings. Similarly the ''footprint'' of the mining activity has been reduced to a very small area and the site is restored as-close-as-possible to pre-mining status. This paper describes the evolution of disposal and reclamation methods and the criteria which have determined the development path followed. Remediation techniques to bring older and now unacceptable tailings deposits into satisfactory compliance with current regulations are reviewed. Some monitoring results are presented. All of the uranium mines in Elliot Lake, Ontario, a large uranium producer since 1957, are now permanently closed. Considerable progress has been made on decommissioning the tailings areas by developing long term maintenance of water covers on some, and water treatment plants and stable soil covers on the others. The innovative methods being used to develop the water covers are described, along with the challenges remaining. Methods now under development in Saskatchewan for subaqueous deposition of paste tailings for permanent disposal in mined out open pits are also described. This method will provide for the first time, ''walkaway'', meaning no long term monitoring and maintenance will be required

    1996-12-01

    On May 26, 1994, the Defense Nuclear Facilities Safety Board (DNFSB) issued Recommendation 94-1, which expressed the board's concern about nuclear materials left in the manufacturing pipeline after the US halted its nuclear weapons production activities. The DNFSB emphasized the need for remediation of these materials. As part of Recommendation 94-1, the DNFSB defined research objectives as follows: that a research program be established to fill any gaps in the information base needed for choosing among the alternate processes to be used in safe conversion of various types of fissile materials to optimal forms for safe interim storage and the longer-term disposition. To achieve this objective a research and technology development program with two elements is needed: a technology-specific program that is focused on treating and storing materials safety, with concomitant development of storage criteria and surveillance requirements, centered around 3- and 8-year targets; and a core technology program to augment the knowledge base about general chemical and physical processing and storage behavior and to assure safe interim material storage until disposition policies are formulated. The paper reports the progress on the following: materials identification and surveillance; stabilization process development; surveillance and monitoring; core technologies; and project management

    2012-01-01

    The purpose of this paper is to present the progress of the work on the EURATOM project STYLE (Structural integrity for lifetime management - non-RPV components). The project focuses on the structural integrity assessment of reactor coolant pressure boundary components (RCPB) relevant to ageing and life time management. The 4-years project started in January 2010 and is now in its third year. Within STYLE realistic failure models for some of the key components will be identified. The range of assessment tools considered will include those for assessment of component failure by advanced fracture mechanics analyses validated on small and large scale experiments, quantification of weld residual stresses by numerical analysis and by measurements, stress corrosion crack initiation and growth effects and assessment of RCPB components (excluding the reactor pressure vessel) under dynamic and seismic loading. Based on theoretical and experimental results, performance assessment and further development of simplified engineering assessment methods (EAM) will be carried out considering both deterministic and probabilistic approaches. Integrity assessment case studies and large scale demonstration experiments will be performed on Mock-ups of safety relevant components. These will include a repair weld in an aged butt-welded austenitic pipe, a dissimilar narrow gap TIG weld (following the EPR design) and a cladded ferritic pipe. Moreover, experiments on specimens and feature test pieces will be carried out to support the large scale Mock-up analyses. The end product of the project ('STYLE TOOLS') will comprise best practice guidelines on the use of advanced tools, on improvement and qualification of EAM as a part of European Leak-before-break (LBB) procedures and on life time management of the integrity of RCPB components in European nuclear power plants. The project is interacting with the European Network of Excellence NUGENIA (former NULIFE). (author)

    The objective of this study is to investigate the progression of predominantly choreatic and hypokinetic-rigid signs in Huntington's disease (HD) and their relationship with cognitive and general functioning over time. The motor signs in HD can be divided into predominantly choreatic and hypokinetic-rigid subtypes. It has been reported in cross-sectional studies that predominantly choreatic HD patients perform better on functional and cognitive assessments compared to predominantly hypokinetic-rigid HD patients. The course of these motor subtypes and their clinical profiles has not been investigated longitudinally. A total of 4135 subjects who participated in the European HD Network REGISTRY study were included and classified at baseline as either predominantly choreatic (n = 891), hypokinetic-rigid (n = 916), or mixed-motor (n = 2328), based on a previously used method. The maximum follow-up period was 6 years. The mixed-motor group was not included in the analyses. Linear mixed models were constructed to investigate changes in motor subtypes over time and their relationship with cognitive and functional decline. Over the 6-year follow-up period, the predominantly choreatic group showed a significant decrease in chorea, while hypokinetic-rigid symptoms slightly increased in the hypokinetic-rigid group. On the Total Functional Capacity, Stroop test, and Verbal fluency task the rate of change over time was significantly faster in the predominantly choreatic group, while on all other clinical assessments the decline was comparable for both groups. Our results suggest that choreatic symptoms decrease over time, whereas hypokinetic-rigid symptoms slightly increase in a large cohort of HD patients. Moreover, different motor subtypes can be related to different clinical profiles.

    New ionosphere and electrodynamics modules have been incorporated in the thermosphere and ionosphere eXtension of the Whole Atmosphere Community Climate Model (WACCM-X), in order to self-consistently simulate the coupled atmosphere-ionosphere system. The first specified dynamics WACCM-X v.2.0 results are compared with several data sets, and with the Thermosphere-Ionosphere-Electrodynamics General Circulation Model (TIE-GCM), during the deep solar minimum year. Comparisons with Thermosphere Ionosphere Mesosphere Energetics and Dynamics satellite of temperature and zonal wind in the lower thermosphere show that WACCM-X reproduces the seasonal variability of tides remarkably well, including the migrating diurnal and semidiurnal components and the nonmigrating diurnal eastward propagating zonal wavenumber 3 component. There is overall agreement between WACCM-X, TIE-GCM, and vertical drifts observed by the Communication/Navigation Outage Forecast System (C/NOFS) satellite over the magnetic equator, but apparent discrepancies also exist. Both model results are dominated by diurnal variations, while C/NOFS observed vertical plasma drifts exhibit strong temporal variations. The climatological features of ionospheric peak densities and heights (NmF2 and hmF2) from WACCM-X are in general agreement with the results derived from Constellation Observing System for Meteorology, Ionosphere and Climate (COSMIC) data, although the WACCM-X predicted NmF2 values are smaller, and the equatorial ionization anomaly crests are closer to the magnetic equator compared to COSMIC and ionosonde observations. This may result from the excessive mixing in the lower thermosphere due to the gravity wave parameterization. These data-model comparisons demonstrate that WACCM-X can capture the dynamic behavior of the coupled atmosphere and ionosphere in a climatological sense.

    2015-01-01

    NASA's Space Launch System (SLS) made significant progress on the manufacturing floor and on the test stand in 2014 and positioned itself for a successful Critical Design Review in mid-2015. SLS, the world's only exploration-class heavy lift rocket, has the capability to dramatically increase the mass and volume of human and robotic exploration. Additionally, it will decrease overall mission risk, increase safety, and simplify ground and mission operations - all significant considerations for crewed missions and unique high-value national payloads. Development now is focused on configuration with 70 metric tons (t) of payload to low Earth orbit (LEO), more than double the payload of the retired Space Shuttle program or current operational vehicles. This "Block 1" design will launch NASA's Orion Multi-Purpose Crew Vehicle (MPCV) on an uncrewed flight beyond the Moon and back and the first crewed flight around the Moon. The current design has a direct evolutionary path to a vehicle with a 130t lift capability that offers even more flexibility to reduce planetary trip times, simplify payload design cycles, and provide new capabilities such as planetary sample returns. Every major element of SLS has successfully completed its Critical Design Review and now has hardware in production or testing. In fact, the SLS MPCV-to-Stage-Adapter (MSA) flew successfully on the Exploration Flight Test (EFT) 1 launch of a Delta IV and Orion spacecraft in December 2014. The SLS Program is currently working toward vehicle Critical Design Review in mid-2015. This paper will discuss these and other technical and programmatic successes and challenges over the past year and provide a preview of work ahead before the first flight of this new capability.

  18. 60 years of advances in neuropsychopharmacology for improving brain health, renewed hope for progress.

    Pharmacotherapy is effective in helping many patients suffering from psychiatric and neurological disorders, and both psychotherapeutic and stimulation-based techniques likewise have important roles to play in their treatment. However, therapeutic progress has recently been slow. Future success for improving the control and prevention of brain disorders will depend upon deeper insights into their causes and pathophysiological substrates. It will also necessitate new and more rigorous methods for identifying, validating, developing and clinically deploying new treatments. A field of Research and Development (R and D) that remains critical to this endeavour is Neuropsychopharmacology which transformed the lives of patients by introducing pharmacological treatments for psychiatric disorder some 60 years ago. For about half of this time, the European College of Neuropsychopharmacology (ECNP) has fostered efforts to enhance our understanding of the brain, and to improve the management of psychiatric disorders. Further, together with partners in academia and industry, and in discussions with regulators and patients, the ECNP is implicated in new initiatives to achieve this goal. This is then an opportune moment to survey the field, to analyse what we have learned from the achievements and failures of the past, and to identify major challenges for the future. It is also important to highlight strategies that are being put in place in the quest for more effective treatment of brain disorders: from experimental research and drug discovery to clinical development and collaborative ventures for reinforcing "R and D". The present article sets the scene, then introduces and interlinks the eight articles that comprise this Special Volume of European Neuropsychopharmacology. A broad-based suite of themes is covered embracing: the past, present and future of "R and D" for psychiatric disorders; complementary contributions of genetics and epigenetics; efforts to improve the

    A previously published study found positive outcomes for a novel technique for ultrasound-guided percutaneous ultrasonic tenotomy, showing good tolerability, safety, and early efficacy within an office setting. In this follow-up study, all 20 members of the original cohort were contacted after 3 years to explore the sustainability of symptomatic relief, functional improvement, and sonographic soft tissue response for percutaneous ultrasonic tenotomy. Case series; Level of evidence, 4. All 20 subjects of the clinical trial that was performed from June to November 2011 were further assessed at 36 months after the procedure in terms of visual analog scale for pain, Disabilities of the Arm, Shoulder and Hand (DASH)-Compulsory/Work scores, need for adjunct procedures, and overall satisfaction. Importantly, all 20 were reassessed with ultrasound imaging at 36 months, and evidence of the common extensor tendon response was assessed in terms of tendon hypervascularity, tendon thickness, and the progress of the hypoechoic scar tissue. A 100% clinical follow-up was achieved, inclusive of ultrasonographic assessment. None of the subjects required further treatment procedures, and 100% expressed satisfaction. Previous improvements in visual analog scale (current median ± SD, 0 ± 0.9; range, 0-3) and DASH-Work scores (current median, 0 ± 0) were sustained with conformity to a linear pattern on polynomial measures. There was further reduction in DASH-Compulsory scores to a median of 0 ± 0.644 (range, 0-2) with a significant decrease on repeated measures (P = .008). Tendon hypervascularity was resolved in 94% of patients, and 100% had reduction in tendon thickness. Overall reduction in the hypoechoic scar tissue was observed in all subjects, with a 90% response achieved by 6 months. Between 6 and 36 months, further reduction in the scar was observed in around 60% of patients, with 20% of patients having complete resolution of the hypoechoic scar. Minimally invasive

    The scope of this report involves a safety evaluation of the reactor pressure vessel (RPV) against neutron embrittlement, in the most severely irradiation region (belt line) and in the event of a pressurized thermal shock. The irreplaceable RPV is considered to be the most critical component for lifetime considerations of the nuclear power plant. However, an application for operation extension will also depend upon a number of additional considerations, including the technical assessment of other plant components, as well as non-technical arguments (e.g. political, environmental, economical, strategical that are outside the scope this report. In the hypothesis of a request for operation extension, it is the responsibility of the utilities to provide the safety authorities with an exhaustive dossier demonstrating that safe extended operation is guaranteed. The role of the safety authorities is to critically evaluate the safety dossier for eventually granting the operation extension.

  6. Status and progress of the RERTR program in the year 2003

    Travelli, Armando

    2003-01-01

    One of the most important events affecting the RERTR program during the past year was the decision by the U.S. Department of Energy to request the U.S. Congress to significantly increase RERTR program funding. This decision was prompted, at least in part, by the terrible events of September 11, 2001, and by a high-level U.S./Russian Joint Expert Group recommendation to immediately accelerate RERTR program activities in both countries, with the goal of converting all the world's research reactors to low-enriched fuel at the earliest possible time, and including both Soviet-designed and United States-designed research reactors. The U.S. Congress is expected to approve this request very soon, and the RERTR program has prepared itself well for the intense activities that the 'Accelerated RERTR Program' will require. Promising results have been obtained in the development of a fabrication process for monolithic LEU U-Mo fuel. Most existing and future research reactors could be converted to LEU with this fuel, which has a uranium density between 15.4 and 16.4 g/cm 3 and yielded promising irradiation results in 2002. The most promising method hinges on producing the monolithic meat by cold-rolling a thin ingot produced by casting. The aluminum clad and the meat are bonded by friction stir welding and the cladding surface is finished by a light cold roll. This method can be applied to the production of miniplates and appears to be extendable to the production of full-size plates, possibly with intermediate anneals. Other methods planned for investigation include high temperature bonding and hot isostatic pressing. The progress achieved within the Russian RERTR program, both for the traditional tube-type elements and for the new 'universal' LEU U-Mo pin-type elements, promises to enable soon the conversion of many Russian-designed research and test reactors. Irradiation testing of both fuel types with LEU U-Mo dispersion fuels has begun. Detailed studies are in progress to

    2018-04-01

    This study aimed to investigate the radiographic measurements associated with the progression of hallux valgus during at least 2 years of follow-up. Seventy adult patients with hallux valgus who were followed for at least 2 years and underwent weightbearing foot radiography were included. Radiographic measurements included the hallux valgus angle (HVA), hallux interphalangeal angle, intermetatarsal angle (IMA), metatarsus adductus angle, distal metatarsal articular angle (DMAA), tibial sesamoid position, anteroposterior (AP) talo-first metatarsal angle, and lateral talo-first metatarsal angle. Patients were divided into progressive and nonprogressive groups. Binary logistic regression analysis was performed to identify factors that significantly affected the progression of hallux valgus deformity. The correlation between change in HVA and changes in other radiographic indices during follow-up was analyzed. The DMAA ( P = .027) and AP talo-first metatarsal angle ( P = .034) at initial presentation were found to be significant factors affecting the progression of hallux valgus deformity. Change in the HVA during follow-up was significantly correlated with changes in the IMA ( r = 0.423; P = .001) and DMAA ( r = 0.541; P < .001). The change in the HVA was found to be significantly correlated with changes in the IMA and DMAA. A future study is required to elucidate whether this correlation can be explained by the progressive instability of the first tarsometatarsal joint. We believe special attention needs to be paid to patients with pes planus and increased DMAA. Level III, comparative study.

    International Nuclear Information System (INIS)

    Marignac, Yves

    2014-01-01

    This report first proposes an overview of the lifetime extension problematic (PLEX) for nuclear plants in a general context (strategy of lifetime extension, and uncertainty and lack of return on experience), and in the case of France (emergence of a strategy of lifetime extension, economic challenges of an extension, uncertainty on investments required by an extension, risk of imposed implicit decisions). It gives a rather detailed overview of the French nuclear reactor fleet, of the status of EDF-operated reactors (construction stages, main lifetime events, regulatory situation of currently exploited reactors) and of their characteristics (common operation principle, main components, main safety functions, main considered severe accidents). It addresses safety issues related to ageing and to the post-Fukushima re-assessment (problematic, robustness increase, limits and weaknesses of additional safety assessments). It presents the currently performed improvements (safety referential, applicable strengthening requirements like safety re-examinations and requirements introduced after Fukushima, applied strengthening prescriptions drawn from additional safety assessments or from the third decennial inspection, with their limitations and perspectives). It proposes strengthening scenarios along with their challenges (in terms of requirement level, procedure and agenda). Three scenarios are proposed (degraded safety, preserved safety, strengthened safety) and analysed in terms of protection against aggressions, diffuse robustness, prevention and management of reactor accident, prevention and management of pool accidents, ultimate control and assistance means. Scenarios are finally compared in terms of costs

  20. Multisystem Disease, Including Eosinophilia and Progressive Hyper-Creatine-Kinase-emia over 10 Years, Suggests Mitochondrial Disorder

    Directory of Open Access Journals (Sweden)

    Josef Finsterer

    2017-04-01

    Full Text Available Background: Eosinophilia has not been reported as a manifestation of a mitochondrial disorder (MID. Here, we report a patient with clinical features suggesting a MID and permanent eosinophilia, multisystem disease, and progressive hyper-creatine-kinase (CK-emia for at least 10 years. Materials and Methods: Methods applied included a clinical exam, blood chemical investigations, electrophysiological investigations, imaging, and invasive cardiological investigations. The patient was repeatedly followed up over several years. He required replacement cardiac surgery. Results: In a 57-year-old male, eosinophilia was first detected at the age of 44 years and has remained almost constantly present until today. In addition to eosinophilia, he developed progressive hyper-CK-emia at the age of 47 years. His history was further positive for hepatopathy, hyperlipidemia, hypothyroidism, renal insufficiency, spontaneous Achilles tendon rupture, double vision, exercise intolerance, muscle aching, mild hypoacusis, sensory neuropathy, seizures, and mitral insufficiency/stenosis requiring valve replacement therapy, oral anticoagulation, and pacemaker implantation. Based on the multisystem nature of his abnormalities and permanent hyper-CK-emia, a MID was suspected. Conclusion: Eosinophilia can be associated with a MID with myopathy, possibly as a reaction to myofiber necrosis. If eosinophilia is associated with progressive hyper-CK-emia and multisystem disease, a MID should be suspected.

  1. Behavioral and Academic Progress of Children Displaying Substantive ADHD Behaviors in Special Education: A 1-Year Follow-up.

    Stoutjesdijk, Regina; Scholte, Evert M; Swaab, Hanna

    2016-01-01

    Exploring differences in behavioral and academic progress between children displaying substantive ADHD behaviors (M age of 9.4 years) in special schools (n = 38) and in inclusive education (n = 26). The contribution of pedagogical strategies to positive outcomes was also examined. Measurements used were the Teachers' Report Form, the Social Emotional Questionnaire, assessments of academic achievement, and the Pedagogical Methods Questionnaire. Mixed-model ANOVAs and Pearson's correlations were used to analyze the data. Significant progress was found regarding disorder-specific problem behavior and in all academic areas, but no interaction effect was found between time and setting. Correlations indicated that positive behavior reinforcement and emotional support are the pedagogical strategies that contributed most to behavioral adaptation. Children displaying substantive ADHD behaviors in both groups develop equally well in the areas of behavioral and academic functioning where significant progress was found. © The Author(s) 2013.

    A longer period of follow-up, though necessarily involving more slowly-progressive cases, demonstrated widespread changes in both grey and white matter structural MRI measures. The mixed picture of regional decreases and increases in FC is compatible with compensatory change, in what should be viewed as a brain-based disease characterised by larger-scale disintegration of motor and frontal projection cerebral networks.

  3. Coalbed methane multi-stakeholder advisory committee recommendations : progress update : year 3

    International Nuclear Information System (INIS)

    2009-11-01

    The coalbed methane (CBM) multi-stakeholder advisory committee (MAC) was formed in 2003 to address public concerns related to CBM development in Alberta. This progress update discussed activities and recommendations made by the MAC, with particular reference to the following 4 main areas: (1) protecting water resources, (2) enhancing information and knowledge, (3) minimizing surface impacts, and (4) communication and consultation. A second MAC was formed by members from environmental organizations, landowners, the energy industry, and government agencies in 2006 to review progress on the implementation of the recommendations. Members of the committee agree that significant progress has been achieved in relation to the recommendations made by the original MAC. A large number of new directives, guidelines, processes and best management practices have been established, or are currently under development. Approximately 19,000 CBM wells have been developed since the MAC was established in 2003. It was concluded that ongoing work related to the recommendations will ensure that CBM in Alberta continues to be developed in a responsible manner. 1 tab.

    2009-05-01

    The aim of this study was to evaluate the experiences of trainees taking part in an extended (four-year) general practice training programme introduced in the South Eastern region of the Republic of Ireland to replace the previous traditional (three-year) programme. In a qualitative design, eight homogeneous focus groups were held to determine the value of the additional year of training. The first cohort of trainees was interviewed towards the start and at the end of their fourth year. Trainees finishing the following year were also interviewed, as were graduates from the final three-year programme. GP trainers and the four members of the programme directing team comprised two further independent focus groups. Trainees reported that the integration of hospital posts and general practice attachments over the four years was particularly beneficial. The exposure to a variety of different general practices and the opportunity to take part in specialty clinics were considered extremely useful. The fourth year of training was felt to be less pressurised than previous years. Professional and personal development was enhanced; improved readiness to practise and confidence were noted. Perceived disadvantages of extended training included a lack of acknowledgment for doctors in their fourth year and excessive emphasis placed on research during the final year of training. The addition of an extra year of vocational training improves professional and personal development and changes the learning experience for doctors. Doctors felt more confident and ready to enter independent practice at the end of the fourth year of training.

    To analyze the value of novel measures of retinal pigment epithelium-drusen complex (RPEDC) volume to predict 2-year disease progression of intermediate age-related macular degeneration (AMD). Prospective, observational study. Three hundred forty-five AMD and 122 non-AMD participants enrolled in the Age Related Eye Disease Study 2 Ancillary Spectral-Domain (SD) Optical Coherence Tomography (OCT) study. High-density SD OCT macular volumes were obtained at yearly study visits. The RPEDC abnormal thickening (henceforth, OCT drusen) and RPEDC abnormal thinning (RAT) volumes were generated by semiautomated segmentation of total RPEDC within a 5-mm-diameter macular field. Volume change and odds ratio (OR) with 95% confidence intervals (CI) for progression to advanced AMD with choroidal neovascularization (CNV) or central geographic atrophy (GA). Complete volumes were obtained in 265 and 266 AMD eyes and in 115 and 97 control eyes at baseline and at year 2, respectively. In AMD eyes, mean (standard deviation) OCT drusen volume increased from 0.08 mm(3) (0.16 mm(3)) to 0.10 mm(3) (0.23 mm(3); P < 0.001), and RAT volume increased from 8.3 × 10(-4) mm(3) (20.8 × 10(-4) mm(3)) to 18.4 × 10(-4) mm(3) (46.6 × 10(-4) mm(3); P < 0.001). Greater baseline OCT drusen volume was associated with 2-year progression to CNV (P = 0.002). Odds of developing CNV increased by 31% for every 0.1-mm(3) increase in baseline OCT drusen volume (OR, 1.31; 95% CI, 1.06-1.63; P = 0.013). Greater baseline RAT volume was associated with significant 2-year increase in RAT volume (P < 0.001), noncentral GA (P < 0.001), and progression to central GA (P < 0.001). Odds of developing central GA increased by 32% for every 0.001-mm(3) increase in baseline RAT volume (OR, 1.32; 95% CI, 1.14-1.53; P < 0.001). In non-AMD eyes, all volumes were significantly lower than AMD eyes and showed no significant 2-year change. Macular OCT drusen and RAT volumes increased significantly in AMD eyes over 2 years

    The aim of this 3-year prospective study was to examine changes in bone mineral characteristics during pubertal maturation in boys with different BMI values at the beginning of puberty and with different BMI increments during puberty. 26 boys with overweight and obesity (OWB) and 29 normal weight boys (NWB) were studied yearly for 3 years from the age of 11 years to measure the changes in different bone mineral characteristics. The OWB group was further divided into two subgroups according to extensive or non-extensive BMI increment during 3-year period. OWB had higher (P BMC), TB BMC for height, lumbar spine (LS) BMD, and LS BMC compared to NWB. Throughout the study period, OWB gained more TB BMD (P = 0.0001), TB BMC (P = 0.0048), TB BMC for height (P = 0.0124), LS BMD (P = 0.0029), and LS BMC (P = 0.0022) compared to NWB. Also during the study period, TB BMD (P = 0.0065), TB BMC (P = 0.0141), TB BMC for height (P = 0.0199), LS BMD (P = 0.0066), LS apparent volumetric BMD (BMAD) (P = 0.0075), and LS BMC (P = 0.017) increased significantly less in those OWB whose BMI increased more extensively. Extensive BMI gain is associated with lower increments in bone mineral characteristics in boys with overweight and obesity. Unfavorable increment in total body fat mass and percentage during pubertal years could be one reason for that.

    The overall status of the RERTR program at the time of the last RERTR meeting is reviewed and the progress achieved since that meeting is described. In the fuel area, unexpected failures of LEU U-Mo dispersion plates and tubes under irradiation testing have prompted a revision of the plans to qualify these fuels. While potential solutions to the difficulties with U-Mo dispersion fuels are being explored in collaboration with our international partners, greater emphasis has been placed on accelerating development of monolithic LEU U-Mo fuel. The feasibility of converting several Russian-designed research reactors to LEU fuels has been addressed, and progress has been made in the development of LEU based 99 Mo production processes. The Russian RERTR program has made significant advances. A very important event of 2004 was the US DOE establishment of the Global Threat Reduction Initiative (GTRI). This new program accelerates and combines under the same US DOE management several programs, including RERTR, which aim to secure, remove, or dispose of, nuclear and other radioactive materials throughout the world that are vulnerable to theft by terrorists.

    Rall, D.P.

    1988-01-01

    In 1980, the Department of Health and Human Services set national prevention objectives for 1990 in 15 health priority areas, 1 of which is the control of toxic agents and radiation. Ten objectives related to this area are priorities for the national control effort. Progress is reviewed on those priorities within the responsibilities of the Public Health Service. Six key program elements, or types of support activities, are deemed essential to preventing, identifying, and controlling toxic agent and radiation threats. Significant progress has been made toward achieving objectives for which all key program elements have been successfully implemented to provide the requisite know-how, manpower, and tools. Important advances have been made in reducing the blood lead levels of the population, reducing unnecessary exposure to medical X-rays, evaluating the toxicities of chemicals in toxic waste dumps, and improving the scientific and technical information base and its availability for prevention and control efforts. The most important priority for the forseeable future will be to expand our knowledge of potential health risks posed by toxic agents and radiation. Expanded surveillance systems and data bases are essential to determining the extent of the problems in terms of human health effects and for measuring the impact of prevention programs. Emphasis on the activities embodied in the key elements will encourage the expansion of the knowledge base and its effective application to prevention and control problems

    International Nuclear Information System (INIS)

    Schnack, D.D.

    1994-01-01

    In this document the author describes an extension of the spatial gridding techniques to an MHD model suitable for the description of the dynamics of toroidal fusion devices. Since the dominant MHD modes in these devices have relatively long toroidal wavelength, the toroidal coordinate is approximated with finite Fourier series. The unstructured, triangular mesh is used to describe the details of the poloidal geometry. With some exceptions, the hydrodynamic variables are treated in a manner analogous to that used in CFD. These quantities (mass, energy, and momentum) are volume based densities that satisfy scalar or vector conservation laws. The electromagnetic variables (the magnetic flux density B and the electric current density J) are area based densities that satisfy pseudo-vector conservation laws, and have no counterpart in fluid dynamics. These variables are also constrained to remain solenoidal. These quantities are represented on the triangular mesh in a new manner that is an extension of that used on rectangular, structured meshes. In this work the author has chosen to solve the primitive MHD equations in order to make the resulting codes and techniques more generally applicable to problems beyond the narrow scope of tokamak plasmas. The temporal stiffness problems inherent in this description of tokamak dynamics that motivate the reduced MHD model are addressed here with the semi-implicit method of time integration. Finally, the author remarks that, while the present work deals strictly with the MHD equations, other volume based fluid descriptions, such as diffusive transport could easily be adapted to these techniques and coupled with the description of the electromagnetic field presented here

    Mass media content may play an important role in policy change. However, the empirical relationship between media advocacy efforts and tobacco control policy success has rarely been studied. We examined the extent to which newspaper content characteristics (volume, slant, frame, source, use of evidence, and degree of localization) that have been identified as important in past descriptive studies were associated with policy progression over a 2-year period in the context of point-of-sale (POS) tobacco control. We used regression analyses to test the relationships between newspaper content and policy progression from 2012 to 2014. The dependent variable was the level of implementation of state-level POS tobacco control policies at Time 2. Independent variables were newspaper article characteristics (volume, slant, frame, source, use of evidence, and degree of localization) and were collected via content analysis of the articles. State-level policy environment contextual variables were examined as confounders. Positive, significant bivariate relationships exist between characteristics of news content (e.g., high overall volume, public health source present, local quote and local angle present, and pro-tobacco control slant present) and Time 2 POS score. However, in a multivariate model controlling for other factors, significant relationships did not hold. Newspaper coverage can be a marker of POS policy progression. Whether media can influence policy implementation remains an important question. Future work should continue to tease out and confirm the unique characteristics of media content that are most associated with subsequent policy progression, in order to inform media advocacy efforts.

    The progress made by the Advanced Turbine Technology Applications Project (ATTAP) is summarized, with emphasis on the following areas: ceramic materials assessment and characterization, ceramic impact damage assessment, ceramic combustor evaluation, turbine inlet particle separator development, impact-tolerant turbine designs, and net-shape ceramic component fabrications. In the evolutionary ceramics development in the Automotive Gas Turbine (AGT101) and ATTAP programs initial designs were conceived to reduce stresses by using well-established criteria: bodies of revolution were preferred over nonaxisymmetric geometries, sharp corners were avoided, the contact area between components was kept as large as possible, and small parts were preferred over large when feasible. Projects discussed include: initial ceramic component fabrication by ceramic suppliers in 1990, engine test to 1371 C in 1991, 100-hr test bed engine durability test in 1991, and 300-hr test bed engine durability in 1992.

    To describe the changes seen in the wrist in rheumatoid arthritis (RA) on magnetic resonance (MR) imaging obtained at 1 year and 6 years. A cohort of patients with RA has been studied prospectively from symptom onset. MR scans of the dominant wrist in 31 patients obtained at 1 year and 6 years were compared for bone erosions, marrow signal change (oedema), synovial thickness and tenosynovitis. Twenty-two patients had an increase in erosion score in the interval and three patients showed a decrease in erosion score suggesting erosion healing. Fourteen patients had an increase in oedema score in the interval and eight patients had a decrease in oedema score. Synovial thickness increased in 13 patients and decreased in eight. Tenosynovitis increased in 15 patients and decreased in five. Bone erosions developed immediately adjacent to the tenosynovitis in two patients. MR imaging is useful in following the progress of bone erosions, marrow oedema, synovitis and tenosynovitis in RA. (orig.)

    Long-term safety and efficacy of osteoporosis treatment are important because of the chronic nature of the disease. We aimed to assess the long-term safety and efficacy of denosumab, which is widely used for the treatment of postmenopausal women with osteoporosis. In the multicentre, randomised, double-blind, placebo-controlled, phase 3 FREEDOM trial, postmenopausal women aged 60-90 years with osteoporosis were enrolled in 214 centres in North America, Europe, Latin America, and Australasia and were randomly assigned (1:1) to receive 60 mg subcutaneous denosumab or placebo every 6 months for 3 years. All participants who completed the FREEDOM trial without discontinuing treatment or missing more than one dose of investigational product were eligible to enrol in the open-label, 7-year extension, in which all participants received denosumab. The data represent up to 10 years of denosumab exposure for women who received 3 years of denosumab in FREEDOM and continued in the extension (long-term group), and up to 7 years for women who received 3 years of placebo and transitioned to denosumab in the extension (crossover group). The primary outcome was safety monitoring, comprising assessments of adverse event incidence and serious adverse event incidence, changes in safety laboratory analytes (ie, serum chemistry and haematology), and participant incidence of denosumab antibody formation. Secondary outcomes included new vertebral, hip, and non-vertebral fractures as well as bone mineral density (BMD) at the lumbar spine, total hip, femoral neck, and one-third radius. Analyses were done according to the randomised FREEDOM treatment assignments. All participants who received at least one dose of investigational product in FREEDOM or the extension were included in the combined safety analyses. All participants who enrolled in the extension with observed data were included in the efficacy analyses. The FREEDOM trial (NCT00089791) and its extension (NCT00523341) are both

    The purpose of the study was to look at some of the potential problems associated with reseeding or reclamation in the buffer zone at the Rocky Flats nuclear weapons plant near Golden, Colorado. During the time covered by this report, another contract dealing with the Grasslands Irradiation Site was transferred to this contract. It was proposed that plant sensitivity to an internal alpha dose, such as might be encountered on Pu contaminated or uranium mine mill tailing contaminated soils, be measured using chromosome aberrations as the end point. This three year report is divided into two subproject reports; one dealing with the Rocky Flats work and one dealing with the grasslands irradiation study. The objectives of the first study were to determine a rapid and feasible method of revegetation;determine a revegetation method such that the vegetation will revert to a natural system as rapidly as possible; and develop a predictive model for soil movement by wind during the revegetation period. The results of the second investigation to date are as follows. There was no change in diversity over the last 3 year period. There was no change in coefficient of community over the last 3 year period. There was no change in Bogr cover over the last 3 year period, but there has been a steady but slow decline in the exposure rate resulting in a Bogr cover equal to 50% of the no effects mean since the second year of irradiation

    The research has been directed to the two areas of x-ray diffraction and bioluminescence, with emphasis in the area of x-ray detection. Interest in x-ray image intensification techniques for biological and medical applications is long standing, and more and more utilized each year. During the past year, as the result of publications and participation in several workshops, the demonstrated advantages of our system over fast scan TV systems and multiwire chambers have become recognized, and several groups have requested us to supply them with a similar system. This is particularly true for use at the synchrotron x-ray sources. Although in recent years less effort has been spent in bioluminescence studies, results have been numerous, both in instrumentation development and experimental results. Bioluminescence is not only of interest in itself, but is a powerful tool for nondestructive study of other biological processes

    In order to increase cancer professionals in Japan, the first phase of training plan for cancer professionals was performed for 5 years from 2007t o 2011, and the second one was performed for 5 years from 2012 to 2016. 95 universities for 18 hubs in the first phase and 100 universities for 15 hubs in the second one participated in this project 2,590 graduate students in the first phase and 2,319 students for 3 years in the second phase learned. Although the number of cancer professionals increased after the start of this project, it is still half of the set points and more efforts are required for this project. From 2017, the new training plan for cancer professionals will start for the third phase, and various professionals such as genome medicine professionals, rare cancer professionals, pediatric cancer professionals and those for the life-stage problems in cancer patients will be educated.

  6. Early understandings of simple food chains: A learning progression for the preschool years

    Science.gov (United States)

    Allen, Michael

    2017-07-01

    Aspects of preschoolers' ecological understandings were explored in a cross-age, quantitative study that utilised a sample of seventy-five 3- to 5-year-old children. Specifically, their concepts of feeding relationships were determined by presenting physical models of three-step food chains during structured interviews. A majority of children, particularly 5-year olds, were capable of grasping concepts inherent in food chain topics that are scheduled to appear later in their schooling. In part, age differences in children's reasoning can be accounted for by attentional theory based on evolutionary predator avoidance adaptations, which tended to become significant at 5 years. Data suggest that these aspects of preschool ecological education could be increased in sophistication, thus accelerating children's understandings about the environment beyond what is currently the case.

    Heusinger, Jannik; Weber, Stephan

    2017-01-15

    Green roofs are discussed as a promising type of green infrastructure to lower heat stress in cities. In order to enhance evaporative cooling, green roofs should ideally have similar Bowen ratio (β=sensible heat flux/latent heat flux) characteristics such as rural sites, especially during summer periods with high air temperatures. We use the eddy-covariance (EC) method to quantify the energy balance of an 8600m 2 extensive, non-irrigated green roof at the Berlin Brandenburg Airport, Germany over a full annual cycle. To understand the influence of water availability on green roof-atmosphere energy exchange, we studied dry and wet periods and looked into functional relationships between leaf area, volumetric water content (VWC) of the substrate, shortwave radiation and β. The surface energy balance was dominated by turbulent heat fluxes in comparison to conductive substrate heat fluxes. The Bowen ratio was slightly below unity on average but highly variable due to ambient meteorology and substrate water availability, i.e. β increased to 2 in the summer season. During dry periods mean daytime β was 3, which is comparable to typical values of urban instead of rural sites. In contrast, mean daytime β was 0.3 during wet periods. Following a summer wet period the green roof maximum daily evapotranspiration (ET) was 3.3mm, which is a threefold increase with respect to the mean summer ET. A multiple regression model indicated that the substrate VWC at the present site has to be >0.11m 3 m -3 during summer high insolation periods (>500Wm -2 ) in order to maintain favourable green roof energy partitioning, i.e. mid-day βurban green roofs can be significantly optimised by using sustainable irrigation approaches.

    The Japanese commercial reactors have accumulated more than 40 years operating experience since Tsuruga-1 started commercial operation in March 1970. However, the severe accident occurred at Fukushima nuclear power plants triggered by East Japan Great Earthquake on March 11 last year. The facts that all the reactors having experienced core meltdown had operated for more than 30 years and Fukushima Daiichi unit 1 had just received the approval for its 40th year Ageing Management Technical Evaluation results from the Japanese government caused increasing distrust among the public in nuclear power plants operating for a long period of time. However, investigations of the accident conducted so far have not revealed any evidence that ageing degradation accelerated the accident. In addition, the analysis of seismic accelerations of the earthquake did not show that any component function was lost due to the accident. Considering these facts, I would like to discuss the issues to be continuously pursued and to be additionally implemented as part of the plat life management activities. In addition, I will introduce the efforts made by the Japanese utilities following the accident. (author)

  12. 175 Years of Progress in PTSD Therapeutics: Learning From the Past.

    Science.gov (United States)

    Stein, Murray B; Rothbaum, Barbara O

    2018-06-01

    Traumatic stressors have always been a part of the human experience. What is now referred to as posttraumatic stress disorder (PTSD) was first studied in the context of military trauma during the Civil War and World War I but most extensively in World War II. Much of what we know about the medical and psychological management of PTSD has its origins in military psychiatric approaches, and a review of these practices reveals important tenets that should be applied in current treatment for both military and nonmilitary PTSD. These practices include intervention as soon as possible after the traumatic exposure, provision for a safe and supportive therapeutic milieu designed for an individual's relatively rapid return to his or her responsibilities and normal activities, and using a combination of pharmacotherapy and psychotherapy (especially exposure to the traumatic memory). A review of current guidelines for treatment of PTSD reveals that few treatments are endorsed with great certainty, owing in large part to a paucity of clinical trials, particularly of pharmacotherapy. This shortcoming must be addressed to enable translation of promising discoveries in the neuroscience of fear into the therapeutic advances patients need and deserve.

  18. Fiscal year 2001 annual progress report for StreamNet the Northwest Aquatic Information Network.; ANNUAL

    International Nuclear Information System (INIS)

    Schmidt, Bruce R.

    2002-01-01

    This report presents accomplishments of the StreamNet project for Fiscal Year 2001 (FY-01). The report is organized by Task, rather than by participating agency, to clearly link accomplishments by all project participants to the individual Tasks and responsibilities detailed in the FY-01 Statement of Work. The StreamNet Project was somewhat hampered in FY-01 by a delay in final approval of the project budget. The effective project budget has been eroded by cost of living adjustments not keeping up with the actual inflationary cost increases. For example, the project was recently impacted by an unanticipated increase in the federal pay scales for computer technology personnel. This is significant because the project budget is primarily composed of personnel costs (84%). Resultant reductions in workforce have led to a consistent decrease in the ability of the project to conduct its work. The budget request for FY-01 was initially proposed to make up for past differences, but the size of the requested increase caused additional review, and the final budget was not approved until approximately half way through the fiscal year. The increased request was not granted and only a 5% cost of living increase was approved. This resulted in some work beginning late and some work not being done. Several staff members at the Regional level could be funded for only 9 months, forcing those positions to do other work on other contracts for part of the year. A contract to develop data compilations for subbasin summaries through NWPPC helped bridged that gap this year. The ODFW StreamNet Project had significant job vacancies in FY-01, so they took the largest proportion of the budget shortfall of the project cooperators for this year. This allowed the other cooperators to function more at a normal level, but resulted in Oregon not being able to update as many data sets as planned. Oregon was able to fill its vacant database manager position later in the year, and this person has

    recordings and landslides occurred) and to use them to define more robust relationships between rainfalls and landslide triggering, with the final aim to increase the forecasting effectiveness of the warning system. The updated rainfall and landslide database were used to periodically perform a quantitative validation and to analyze the errors affecting the system forecasts. The errors characterization was used to implement a continuous process of updating and modification of SIGMA, that included: - Main model upgrades (generalization from a pilot test site to the whole Emilia Romagna region; calibration against well documented landslide events to define specific σ levels for each territorial units; definition of different alert levels according to the number of expected - Ordinary updates (periodically, the new landslide and rainfall data were used to re-calibrate the thresholds, taking into account a more robust sample). - Model tuning (set up of the optimal version of the decisional algorithm, including different definitions of "long" and "short" periods; selection of the optimal reference rain gauge for each Territorial Unit; modification of the boundaries of some territorial - Additional features (definition of a module that takes into account the effect of snow melt and snow accumulation; coupling with a landslide susceptibility model to improve the spatial accuracy of the model). - Various performance tests (including the comparison with alternate versions of SIGMA or with thresholds based on rainfall intensity and duration). This process has led to an evolution of the warning system and to a documented improvement of its forecasting effectiveness. Landslide forecasting at regional scale is a very complex task, but as time passes by and with the systematic gathering of new substantial data and the continuous progresses of research, uncertainties can be progressively reduced and a warning system can be set that increases its performances and reliability with time.

  20. LMFBR flexible pipe joint development program. Annual technical progress report, government fiscal year 1977

    International Nuclear Information System (INIS)

    1978-01-01

    Currently, the ASME Boiler and Pressure Vessel Code does not allow the use of flexible pipe joints (bellows) in Section III, Class 1 reactor primary piping systems. Studies have shown that the primary piping loops of LMFBR's could be simplified by using these joints. This simplification translates directly into shorter primary piping runs and reduced costs for the primary piping system. Further cost savings result through reduced vault sizes and reduced containment building diameter. In addition, the use of flexible joints localizes the motions from thermally-induced piping growth into components which are specifically designed to accommodate this motion. This reduces the stress levels in the piping system and its components. It is thus economically and structurally important that flexible piping joints be available to the LMFBR designer. The overall objective of the Flexible Joint Program is to provide this availability. This will be accomplished through the development of ASME rules which allow the appropriate use of such joints in Section III, Class 1 piping systems and through the development and demonstration of construction methods which satisfy these rules. The rule development includes analytic and testing methodology formulations which will be supported by subscale bellows testing. The construction development and demonstration encompass the design, fabrication, and in-sodium testing of prototypical LMFBR plant-size flexible pipe joints which meet all ASME rule requirements. The satisfactory completion of these developmental goals will result in an approved flexible pipe joint design for the LMFBR. Progress is summarized in the following efforts undertaken during 1977 to accomplish these goals: (1) code case support, (2) engineering and design, (3) material development, (4) testing, and (5) manufacturing development

    Full Text Available In the Iowa Gambling Task (IGT subjects need to find a way to earn money in a context of variable wins and losses, conflicting short-term and long-term pay-off, and uncertainty of outcomes. In 2006, we published the first rodent version of the IGT (r-IGT; Behavior Research Methods 38, 470-478. Here, we discuss emerging ideas on the involvement of different prefrontal-striatal networks in task-progression in the r-IGT, as revealed by our studies thus far. The emotional system, encompassing, among others, the orbitofrontal cortex, infralimbic cortex and nucleus accumbens (shell and core area, may be involved in assessing and anticipating the value of different options in the early stages of the task, i.e. as animals explore and learn task contingencies. The cognitive control system, encompassing, among others, the prelimbic cortex and dorsomedial striatum, may be involved in instrumental goal-directed behaviour in later stages of the task, i.e. as behaviour towards long-term options is strengthened (reinforced and behaviour towards long-term poor options is weakened (punished. In addition, we suggest two directions for future research: (1 the role of the internal state of the subject in decision-making, and (2 studying differences in task-related costs. Overall, our studies have contributed to understanding the interaction between the emotional system and cognitive control system as crucial to navigating human and non-human animals alike through a world of variable wins and losses, conflicting short-term and long-term pay-offs, and uncertainty of outcomes.

    1987-01-01

    A Nuclear Waste Fund established by the Nuclear Waste Policy Act of 1982 provides financial support to affected states to participate in the high-level radioactive waste repository siting program of the US Department of Energy. In Rhode Island, that function was performed by a multidisciplinary Project Review Team consisting of staff from three State agencies. Members of the Review Team attended several meetings in 1986 to discuss mutual concerns with Federal, State and Tribal officials. Comments were developed on DOE's Draft Area Recommendation Report. Members of the Review Team also testified at a public hearing in Providence on the Draft ARR, and developed and distributed a public information booklet. In May, Secretary of Energy John Herrington announced the suspension of the crystalline repository siting program. The remainder of the year was spent monitoring litigation challenging that decision and pending legislation. Administrative phase-down of the program was essentially complete by the close of the calendar year

    'Goals of the project are to (1) identify the key physics and chemistry underlying the use of high pressure plasmas for etching removal of actinides and actinide surrogates; and (2) identify key surface reactions and plasma physics necessary for optimization of the atmospheric pressure plasma jet. Technical description of the work decommissioning of transuranic waste (TRU) into low-level radioactive waste (LLW) represents the largest cleanup cost associated with the nuclear weapons complex. This work is directed towards developing a low-cost plasma technology capable of converting TRU into LLW, based upon highly selective plasma etching of plutonium and other actinides from contaminated surfaces. In this way, only the actinide material is removed, leaving the surface less contaminated. The plasma etches actinide material by producing a volatile halide compound, which may be efficiently trapped using filters. To achieve practical, low-cost operation of a plasma capable of etching actinide materials, the authors have developed a y-mode, resonant-cavity, atmospheric pressure plasma jet (APPJ). In contrast to conventional, low pressure plasmas, the APPJ produces a purely-chemical effluent free of ions, and so achieves very high selectivity and produces negligible damage to the surface. Since the jet operates outside a chamber, many nuclear wastes may be treated including machinery, duct-work, concrete and other building materials. In some cases, it may be necessary to first remove paint from contaminated surfaces using a plasma selective for that surface, then to switch to the actinide etching chemistry for removal of actinide contamination.

    The potential benefits and dangers of dietary protein restriction in chronic kidney disease (CKD) are still controversial. Thus, the aim of this study is to evaluate the effect of low protein diet (LPD) on the renal function in nondialysis CKD patients. A retrospective study was conducted from 321 nondialysis CKD patient's medical files (65.1 ± 12.7 yrs, 58.2% men). These patients received individualized dietary protein prescription (0.6-0.8 g protein/kg/day). Protein intake was evaluated by food diary and 24 h-food recall. Adherence to the LPD was considered when patients intake from 90 to 110% of the prescribed amount of protein. The patients were divided into 4 groups: (G1) adherent diabetes mellitus (DM) patients (n = 83); (G2) non-adherent DM patients (n = 106); (G3) adherent non-DM patients (n = 75); (G4) non-adherent non-DM patients (n = 57). Renal function was assessed by estimated glomerular filtration rate (eGFR). Both groups of patients (DM and non-DM) that adhered to the LPD showed significant improvement in eGFR (G1: 38.7 ± 13.2 mL/min to 51.1 ± 17.0 mL/min (p patients, no differences in albumin and BMI were observed at the end of follow up. In non-adherent patients, eGFR significantly decreased in DM group (G2: 44.2 ± 18.5 mL/min to 38.2 ± 15.8 mL/min (p = 0.003)). According to multivariate analysis, annual changes in eGFR were not independent associated with age, gender, BMI, lipid profile, bicarbonate or smoking status. In summary, adherence to low protein diet could be able to improve serum creatinine and eGFR, well-known markers of renal function. However, prospective studies are needed to control confounders which affect renal function and CKD progression.

    The aims of the study are to evaluate the efficacy and safety of continuous subcutaneous insulin infusion (CSII) treatment in pre-school children with type I diabetes, and to assess whether the criteria of good metabolic control are achieved. A review was performed on the medical charts of patient's180mg/dl), and hypoglycaemia (<70mg/dl), mean blood glucose, standard deviation and coefficient of variation (SD/mean glucose ×100). Statistical analysis was performed using SPSS. HbA1c decreased from 6.9% (6.7-7.5) to 6.8% (6.4-7.1) after one year of CSII. Afterwards, it remained under 6.8% during the follow-up (median 5 years [3-6]). Prior to CSII, 74% of children had HbA1c levels < 7.5%. It increased to 96% after one year of CSII. Median blood glucose measurements /day was 10 (9-11). Total insulin dose did not change significantly. During the follow-up, there was one episode of DKA and one episode of HS. I/HC at breakfast were higher than at other meals (0.92 vs. 0.55, 0.6 and 0.5, respectively). CSII is effective and safe in pre-school children. It allows good metabolic control (based on Society for Paediatric and Adolescent Diabetes / American Diabetes Association criteria) to be achieved and maintained for long periods of time without an increase in adverse events.

    India established the National Tuberculosis Control Project (NTCP) 50 years ago and re-designed it as Revised NTCP (RNTCP) 19 years ago. Tuberculosis (TB) control was beset with obstacles-BCG vaccination was found ineffective in TB control in 1979; human immunodeficiency virus began spreading in India since 1984 with TB as the commonest opportunistic disease; multi-drug resistance was found to be prevalent since 1992. The World Health Organization declared TB as global emergency in 1993. Yet, RNTCP was extended to the whole nation very slowly, taking 13 years from inception. The first objective of RNTCP, namely 85% treatment success has been achieved and case-fatality had dropped by 90%;. Still, TB burden continues to remain huge; about half the cases are not getting registered under RNTCP; pediatric TB is neglected; TB drains national economy of US$ 23 billion annually. Therefore, TB control is in urgent need of re-design and re-invigoration, with additional inputs and system re-organization to cover all such gaps. We highlight the need for Public Health infrastructure under which all vertical disease control projects such as RNTCP should be synergized for better efficiency and for establishing Public Health Surveillance for collecting denominator-based data on incidence and prevalence to guide course corrections. India ought to spend 3 to 5 times more on TB control than at present. Control needs clear epidemiologic definition and measurable parameters for monitoring the level of control over time. TB control is both a measure of, and a means to, socioeconomic development.

    2013-01-01

    The National Institute for Rocket Propulsion Systems (NIRPS) maintains and advances U.S. leadership in all aspects of rocket propulsion for defense, civil, and commercial uses. The Institute's creation is in response to widely acknowledged concerns about the U.S. rocket propulsion base dating back more than a decade. U.S. leadership in rocket and missile propulsion is threatened by long-term industry downsizing, a shortage of new solid and liquid propulsion programs, limited ability to attract and retain fresh talent, and discretionary federal budget pressures. Numerous trade and independent studies cite erosion of this capability as a threat to national security and the U.S. economy resulting in a loss of global competitiveness for the U.S. propulsion industry. This report covers the period between May 2011 and December 2012, which includes the creation and transition to operations of NIRPS. All subsequent reports will be annual. The year 2012 has been an eventful one for NIRPS. In its first full year, the new team overcame many obstacles and explored opportunities to ensure the institute has a firm foundation for the future. NIRPS is now an active organization making contributions to the development, sustainment, and strategy of the rocket propulsion industry in the United States. This report describes the actions taken by the NIRPS team to determine the strategy, organizational structure, and goals of the Institute. It also highlights key accomplishments, collaborations with other organizations, and the strategic framework for the Institute.

    The US Department of Energy (DOE) created the Nuclear Energy Research Initiative (NERI) in 1999 to conduct research and development with the objectives of: (1) overcoming the principal technical obstacles to expanded nuclear energy use, (2) advancing the state of nuclear technology to maintain its competitive position in domestic and world markets, and (3) improving the performance, efficiency, reliability, and economics of nuclear energy. The NERI program is now beginning its second year with increased funding and an emphasis on international participation. Among the programs selected for funding was the ''Smart Equipment and Systems to Improve Reliability and Safety in Future Nuclear Power Plant Operations''. This program is a 36 month collaborative effort bringing together the technical capabilities of Westinghouse Nuclear Automation, Sandia National Laboratories, Duke Engineering and Services (DE and S), Massachusetts Institute of Technology (MIT) and Pennsylvania State University (PSU). The goal of the program is to design, develop, and evaluate an integrated set of tools and methodologies that can improve the reliability and safety of advanced nuclear power plants through the introduction of smart equipment and predictive maintenance technology. The results have implications for reduced construction costs. This paper discusses: (1) the goals and significance of the program, (2) the significant achievements of the program's first year and the current direction for its continuing efforts and (3) potential cooperation with the domestic nuclear and component manufacturing industries, and with international organizations

    2012-01-01

    The presence of women in urology has gradually increased in the last 35 years with an accelerated rate in the last decade. We evaluated manuscript authorship trends by gender. Manuscript authorship is a metric that has been used as a marker of academic productivity. We hypothesized that the number of first and last author publications by women has increased proportionately to the number of women in the field during the last 35 years. We performed a bibliometric study to examine authorship gender in The Journal of Urology® and Urology®. We reviewed all original articles published from American institutions in 1974, 1979, 1984, 1989, 1994, 1999, 2004 and 2009. Of the 8,313 articles reviewed 5,461 were from American institutions, including 97.5% for which we determined author gender. There were 767 articles with female authors, including 440 first and 327 last authors.

  14. Progressive Incrementalism: U.S Foreign Economic Policy Over the Next Four Years

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available As we look ahead following last year’s U.S. presidential and congressional elections, Canadians — and Canadian business in particular — will want to have a better sense of the economic prospects, as well as the context, of U.S. foreign economic policy over the coming half-decade or so. For, notwithstanding all the talk, debates, op-ed articles, thinktank-pieces and even books in recent years suggesting or asserting the decline of American economic power, Canada’s ever-present integration and interdependence with our southern neighbour is both a reality and now, again, an important, medium-term asset. Over the coming four years and likely beyond, and once it has completed sorting out its “fiscal cliff” matter, the U.S. is positioned to be the source of increasing economic growth. The American economy has strengths: its high productivity and innovation compared to most other countries, massive piles of private sector cash leading to all sorts of investment potential, a devalued currency, and a relatively young workforce compared to the European Union, Japan, and even Canada. Therefore, although the U.S. economy continues to face large challenges related to fiscal imbalances, there are reasons to expect increasing economic growth over the medium term.

  15. Thirty years of progress in applications and modeling of ocean ambient noise

    2012-11-01

    Ambient noise in the ocean is a stochastic process, which traditionally was considered to be a nuisance, since it reduced the detectability of sonar signals of interest. However, over the last thirty years, it has come to be recognized that the ambient noise itself contains useful information about the ocean and ocean processes. To extract the information, various inversion procedures have been developed, based upon which a number of practical applications of the ambient noise have evolved. Since naturally generated ambient noise is always present in the ocean, it has the advantage of being non-invasive and non-damaging to marine life, including marine mammals. In this article, a summary of the commonly encountered ambient noise models is offered, along with the associated inversion procedures, and some of the more recent applications of the ambient noise are highlighted.

    2008-11-01

    For the International Year of Astronomy 2009 (IYA2009), we have designed an educational program based on understanding the basic principles of telescopes and using telescopes for astronomical observations. As part of this program, we have designed an educational telescope kit that can be assembled by students and used to observe the Moon, Jupiter, and Saturn from urban environments. A premise of the project is that for students, the building of their own telescope is far better than getting an assembled one. The Galileoscope is designed to create ``Wow!'' experiences in kids when viewing Saturn, Jupiter, and the Moon. With the Galileoscope, Galileo's observations can be easily duplicated across the country, even in major cities. We have designed the Galileoscope and its associated educational materials for use in a wide variety of educational environments including planetariums, small science and nature centers, classrooms, and amateur astronomy clubs.

    2002-01-01

    This report documents the preliminary needs assessment of high-level waste (HLW) tank lay-up requirements and considerations for the Hanford Site, Idaho National Engineering and Environmental Lab (INEEL), Savannah River Site (SRS) and Oak Ridge Reservation (ORR). This assessment includes the development of a high-level requirements and considerations list that evolved from work done for the West Valley Demonstration Project (WVDP) earlier in fiscal year (FY) 2001, and is based on individual site conditions and tank retrieval/tank closure schedules. Because schedules are continually subject to change, this assessment is considered preliminary and needs review and validation by the individual sites. The lay-up decision methodology developed for WVDP was based on standard systems engineering principles, and provided a structured framework for producing an effective, technically-defensible lay-up strategy

    Air-oxidized PuO 2 , high-fired (850 0 C) PuO 2 , Pu(NO 3 ) 4 , PuF 4 , and PuCl 3 , all of which had known amounts of 241 Am, were implanted over the left metacarpus of beagles. The concentration of plutonium and 241 Am in various tissues was measured as a function of time. The effect of diethylenetriaminepentaacetate (DTPA) therapy on organ deposition was studied. Significant differences in the translocation dynamics of air-oxidized PuO 2 , high-fired PuO 2 , and Pu(NO 3 ) 4 in the left superficial cervical lymph node (LSCLN) were observed by in vivo measurement and radiochemical analysis. A 3 percent buildup of plutonium was observed 2 weeks after implantation of air-oxidized PuO 2 , with an exponential buildup to 17 percent at 1 year. With Pu(NO 3 ) 4 and high-fired PuO 2 , the activity accumulation built up to a peak of 31 and 20 percent, respectively, at 30 and 60 days after implantation, followed by a gradual regression. At the implant site 1 year postimplant, a 70 percent reduction in activity was observed with Pu(NO 3 ) 4 , a 90 percent reduction with PuO 2 (high-fired), and only a 20 percent reduction with air-oxidized PuO 2 . The effect of larger particle size on the movement of plutonium from a wound site was speculated. Chemical form and physical form appear to change the rate of translocation and relative depositions of plutonium and americium in various organs.Particle size was not found to be an important factor in the total movement of plutonium in afferent and efferent lymph. More plutonium moves in the cellular fraction of afferent and efferent lymph regardless of particle size. The clearance of plutonium particles from the lymph nodes was associated with necrosis of macrophages. The effect of DTPA therapy on plutonium concentration was greater for the nitrate than for the other chemical forms

  20. Assessing Progress in Reducing the At-Risk Population after 13 Years of the Global Programme to Eliminate Lymphatic Filariasis

    Hooper, Pamela J.; Chu, Brian K.; Mikhailov, Alexei; Ottesen, Eric A.; Bradley, Mark

    2014-01-01

    Background In 1997, the World Health Assembly adopted Resolution 50.29, committing to the elimination of lymphatic filariasis (LF) as a public health problem, subsequently targeted for 2020. The initial estimates were that 1.2 billion people were at-risk for LF infection globally. Now, 13 years after the Global Programme to Eliminate Lymphatic Filariasis (GPELF) began implementing mass drug administration (MDA) against LF in 2000—during which over 4.4 billion treatments have been distributed in 56 endemic countries—it is most appropriate to estimate the impact that the MDA has had on reducing the population at risk of LF. Methodology/Principal Findings To assess GPELF progress in reducing the population at-risk for LF, we developed a model based on defining reductions in risk of infection among cohorts of treated populations following each round of MDA. The model estimates that the number of people currently at risk of infection decreased by 46% to 789 million through 2012. Conclusions/Significance Important progress has been made in the global efforts to eliminate LF, but significant scale-up is required over the next 8 years to reach the 2020 elimination goal.

    Development of high-temperature superconductors (HTS) has undergone tremendous progress during the past year. Kilometer tape lengths and associated magnets based on BSCCO materials are now commercially available from several industrial partners. Superconducting properties in the exciting YBCO coated conductors continue to be improved over longer lengths. The Superconducting Partnership Initiative (SPI) projects to develop HTS fault current limiters and transmission cables have demonstrated that HTS prototype applications can be produced successfully with properties appropriate for commercial applications. Research and development activities at LANL related to the HTS program for Fiscal Year 1997 are collected in this report. LANL continues to support further development of Bi2223 and Bi2212 tapes in collaboration with American Superconductor Corporation (ASC) and Oxford Superconductivity Technology, Inc. (OSTI), respectively. The tape processing studies involving novel thermal treatments and microstructural characterization have assisted these companies in commercializing these materials. The research on second-generation YBCO-coated conductors produced by pulsed-laser deposition (PLD) over buffer template layers produced by ion beam-assisted deposition (IBAD) continues to lead the world. The applied physics studies of magnetic flux pinning by proton and heavy ion bombardment of BSCCO and YBCO tapes have provided many insights into improving the behavior of these materials in magnetic fields. Sections 4 to 7 of this report contain a list of 29 referred publications and 15 conference abstracts, a list of patent and license activities, and a comprehensive list of collaborative agreements in progress and completed.

    1996-01-01

    In 1995 the DOE grant in Nuclear theory with Professors Rubin H. Landau and Victor A. Madsen as co-principal investigators ended. Their research was carried out in collaboration with graduate students in Corvallis, and with scientists at LLNL-Livermore, Los Alamos, TRIUMF, KFA-Julich, Hamburg University, Melbourne University, The Thinking Machine Corporation and IBM Research. Activities in nuclear and particle physics at Oregon State University (OSU) were diverse and active. Madsen's work concentrated on the relation of reactions to the nuclear structure, and Landau's work concentrated on intermediate energy physics, few-body problems, and computational physics. The Landau group had a weekly meeting of students and visitors. There was a weekly nuclear seminar with experimental and theoretical colleagues, and a weekly departmental colloquium. The DOE support had permitted the group to run Unix workstations networked to other computers in the Physics Department and the University. Since 1990 OSU has been using IBM RISC System 6000/model 530 with console and four X-stations. The equipment was purchased and is maintained with yearly DOE funding of the group

    2012-09-01

    Full Text Available Throughout the 20 year history of U.S. Naval Medical Research Unit No. 2 Detachment (NAMRU, many viruses and viral diseases have been studied. The greatest emphasis has been in the field of arboviruses, specifically dengue virus, chikungunya virus, and Japanese B encephalitis virus. The initial focus of the work was to define the extent of the threat posed by these viruses. Studies were conducted to determine antibody prevalence, and to determine the etiologies of infectious febrile disease in hospitalized patients. Later the work advanced into more specific areas, especially the entomologic and clinical components of these viruses. Little was known of the incidence or kind of arbovirus infections in Indonesia when NAMRU was established. Previous serological studies had used the cross reactive haemagglutination assay. Green et al. in 1973 provided convincing serological evidence of infections with chikungunya virus and group B arboviruses by using the specific virus neutralization assay. These results demonstrated the need for further studies to isolate the causative agent, to describe the epidemiology, and to investigate the clinical features of the associated disease.

    Phyllodes tumours are uncommon breast tumours which account for less than 1% of all breast neoplasms. High-grade malignant phyllodes tumour is a very rare but aggressive breast malignancy and forms approximately 15-30% of all phyllodes tumours. The transformation of a benign fibroadenoma into a malignant phyllodes tumour in a teenaged female is even rarer. We report here an interesting case of malignant phyllodes tumour in a 14-year female patient who was operated twice previously with the diagnosis of complex fibroadenoma in the same breast. There was a large tumour involving whole of the breast and infiltrating the skin. The patient was operated and total mastectomy was done. Diagnosis was confirmed after histopathological examination and immunohistochemistry of the resected specimen. Patient received adjuvant radiotherapy and there was no recurrence on 6-month follow-up. Owing to the rare occurrence of malignant phyllodes tumour in this age group along with previous operations for complex fibroadenoma, this case is being reported here. (author)

    This historical overview of the Journal of Dental Education highlights its founding by and close seventy-five connec-tion with its parent organization, the American Dental Education Association (ADEA). In 1936, the leadership of the American Association of Dental Schools, the predecessor of ADEA, recognized the need for a journal that would keep the new profession of academic dentistry dynamic by providing a means for communicating ideas and new teaching methods. While holding to that mission, the journal has evolved over the years in parallel with ADEA--especially in the twenty-first century with the expansion of both to include allied, dental, and advanced dental education and to address core issues of curriculum change through ADEA's Commission on Change and Innovation in Dental Education (ADEA CCI). Across its history, the journal has actively supported the mission of ADEA by advancing scholarship in dental education. Its past achievements have now set the stage for the journal's next incarnation as a leading global voice in the broader realm of health professions education.

    2008-12-01

    Background Periodic plant and animal cycles driven by seasonal variations in climate (i.e., phenology) set the stage for dynamics of ecosystem processes, determine land surface properties, control biosphere-atmosphere interactions, and affect food production, health, conservation, and recreation. Phenological data and models have applications related to scientific research, education and outreach, as well as to stakeholders interested in agriculture, tourism and recreation, human health, and natural resource conservation and management. The predictive potential of phenology requires a new data resource-a national network of integrated phenological observations and the tools to access and analyze them at multiple scales. The USA National Phenology Network (USA-NPN) is an emerging and exciting partnership between federal agencies, the academic community, and the general public to monitor and understand the influence of seasonal cycles on the Nation's resources. The USA-NPN will establish a wall-to-wall science and monitoring initiative focused on phenology as a tool to understand how plants, animals and landscapes respond to climate variation, and as a tool to facilitate human adaptation to ongoing and potential future climate change. Results The National Coordinating Office of the USA-NPN began operation in August 2007 at the University of Arizona, Tucson, AZ. This first year of operation produced many new phenology products and venues for phenology research and citizen involvement, as well as identification of future directions for the USA NPN. Products include a new web-site (www.usanpn.org) that went live in June 2008; the web-site includes a tool for on-line data entry, and serves as a clearinghouse for products and information to facilitate research and communication related to phenology. The new core Plant Phenology Program includes profiles for 185 vetted local, regional, and national plant species with descriptions and monitoring protocols, as well as

    We sought to evaluate the long term health-related quality of life (HRQOL) in patients survived severely extensive burn and identify their clinical predicting factors correlated with HRQOL. A cross-sectional study was conducted in 20 patients survived more than 2 years with extensive burn involving ≥70% total body surface area (TBSA) between 1997 and 2009 in a burn center in Shanghai. Short Form-36 Medical Outcomes Survey (SF-36), Brief Version of Burn Specific Health Scale (BSHS-B) and Michigan Hand Outcome Questionnaire (MHQ) were used for the present evaluation. SF-36 scores were compared with a healthy Chinese population, and linear correlation analysis was performed to screen the clinical relating factors predicting physical and mental component summary (PCS and MCS) scores from SF-36. HRQOL scores from SF-36 were significantly lower in the domains of physical functioning, role limitations due to physical problems, pain, social functioning and role limitations due to emotional problems compared with population norms. Multiple linear regression analysis demonstrated that only return to work (RTW) predicted improved PCS. While age at injury, facial burns, skin grafting and length of hospital stay were correlated with MCS. Work, body image and heat sensitivity obtained the lowest BSHS-B scores in all 9 domains. Improvements of HRQOL could still be seen in BSHS-B scores in domains of simple abilities, hand function, work and affect even after a quite long interval between burns and testing. Hand function of extensive burn patients obtained relatively poor MHQ scores, especially in those without RTW. Patients with extensive burns have a poorer quality of life compared with that of general population. Relatively poor physical and psychological problems still exist even after a long period. Meanwhile, a trend of gradual improvements was noted. This information will aid clinicians in decision-making of comprehensive systematic regimens for long term rehabilitation

    This paper analyzes Colombia's space policy: its successes, its failures and what it still needs to achieve. The paper examines the interaction among the different players, and how this policy contributes to economic and social development of the country. And postulates that, unless a real national plan of action, with specific milestones and budget as well as a managing agency are developed, this policy may be in danger of disappearing. The Colombian Space Commission (Comisión Colombiana del Espacio, or CCE) was created by Presidential Decree 2442 in 2006. It is a multi-sectorial entity, in charge of coordinating, planning, and leading in the implementation of national policies for the development and application of space technologies. The CCE was also charged with the drafting of plans and programs in this field. The CCE began with only a few members (15) and today is comprised of 47 members: 13 ministries, 4 administrative departments, another 21 governmental entities and 9 universities, the latter acting as consultants. The Vice-President of the Republic is the President of the CCE. These different actors gave great importance to the development of Colombia's space sector, and 6 years later, they are continuing support and development the country's space policy. This analysis takes into account three aspects: first, achieving the objectives of the CCE: the creation and development of a national space policy for Colombia; secondly, focussing on “target groups” and “end users”; and thirdly, the “outcomes” or achievements to date. Some conclusions are worth highlighting: first, the warm reception and support of the CCE by both the public and private sectors on high levels, but the poor knowledge of the national space policy by the Colombian people and the small and medium companies. Secondly, in the context of public policy [9], the strategic plan called “National Policy in regard to Space Activities”, is caught between two phases: the formulation

    approach where nuclear technique; are used to develop new strains of plants of higher quality, yields, and resistance to diseases. These techniques induce genetic variation. Soil fertility, irrigation and crop production covers the important combinations of healthy, productive soils and an adequate supply ol water necessary to achieve good quality crop production. Nuclear techniques are used to improve the efficiency of fertilizers, to understand their environmental effects, and to establish new ways to restrain their use. Agrochemicals and residues are watched through radiotracer techniques as they travel through our environment. More effective applications of pesticides can be devised, as well as new approaches to understand and protect the ecological balance. As the Joint FAO/IAEA Division completes its 25th year in operation, it is an opportune time to review some of the achievements of nuclear methods applied to food and agricultural production. Some of these are quite remarkable and have set valuable precedents in research, development, and applications for nuclear strategies and their role in solving food and agricultural problems in a practical, efficient manner.

    The inclusion of nature of science (NOS) in science education has for a long time been regarded as crucial. There is, however, a lack of research on appropriate NOS aspects for different educational levels. An even more neglected area of research is that focusing on teachers' perspectives on NOS teaching at different levels. The aim of this article is to examine NOS progression in the light of teachers' suggestions and rationales. In order to obtain teachers' informed perspectives, we chose to involve six teachers (teaching grades 1-9) in a 3-year research project. They took part in focus group discussions about NOS and NOS teaching as well as implemented jointly planned NOS teaching sessions. Data that this article builds on was collected at the end of the project. The teachers' suggestions for NOS progression often relied on adding more NOS issues at every stage, thereby creating the foundations of a broader but not necessarily deeper understanding of NOS. Five rationales, for if/when specific NOS issues are appropriate to introduce, emerged from the analysis of the teacher discussions. Some of these rationales, including practice makes perfect and increasing levels of depth can potentially accommodate room for many NOS issues in the science classroom, while maturity and experience instead has a restricting effect on NOS teaching. Also, choice of context and teaching approaches play an important role in teachers' rationales for whether specific NOS issues should be included or not at different stages. The article discusses the implications for teacher education and professional development.

  17. The debate about physician assistance in dying: 40 years of unrivalled progress in medical ethics?

    Science.gov (United States)

    Holm, Søren

    2015-01-01

    Some issues in medical ethics have been present throughout the history of medicine, and thus provide us with an opportunity to ascertain: (1) whether there is progress in medical ethics; and (2) what it means to do good medical ethics. One such perennial issue is physician assistance in dying (PAD). This paper provides an account of the PAD debate in this journal over the last 40 years. It concludes that there is some (but limited) progress in the debate. The distinctions, analogies and hypothetical examples have proliferated, as have empirical studies, but very little has changed in terms of the basic arguments. The paper further argues that many of the contributions to the debate fail to engage fully with the concerns people have about the legal introduction of PAD in the healthcare system, perhaps because many of the contributions sit on the borderline between academic analysis and social activism.

    Full Text Available To develop methods of collagen cross-linking (CXL in the sclera for the treatment of progressive myopia and to investigate the biomechanical and histological changes that occur in as a result.Twenty 14-day-old guinea pigs were divided into 3 groups: the cross-linking group (CL, n = 8, non cross-linking group (NCL, n = 8, and control group (n = 4. The scleras of the right eyes of the guinea pigs in the CL group were surgically exposed and riboflavin was dropped onto the irradiation zone for 20 seconds prior to ultraviolet-A (UVA irradiation. The same procedure was conducted on the NCL group but without UVA irradiation. No procedure was conducted on the control group. The right eyes of the guinea pigs in the CL and NCL groups were then fitted with -10.00DS optics for six weeks. Retinoscopy and the axial lengths (AXL were measured at baseline, and at the second, fourth and sixth weeks post-treatment in all three groups. All animal subjects were euthanized after the sixth week and then biomechanical and histopathological examinations of the scleras were conducted.The mean AXL of the NCL group was longer than both the control and CL groups at six weeks (P = 0.001. The mean refractive error in the NCL group was statistically significantly more negative than both the control and the CL groups at six weeks (P = 0.001. The scleral collagen fiber arrangements of the CL and control groups were denser and more regularly distributed than the NCL group. Ultimate stress of the sclera was lowest in the NCL group, followed by the CL then the control group (P<0.05. Ultimate strain (% of the sclera was lowest in the CL group followed by the NCL and then the control group (P<0.05.Our study demonstrates that scleral CXL using riboflavin UVA irradiation effectively prevents the progression of myopia by increasing scleral biomechanical strength in a guinea pig model.

    The purpose of this study was to retrospectively determine the local control rate and contributing factors to local progression after computed tomography (CT)-guided radiofrequency ablation (RFA) for unresectable lung tumor. This study included 138 lung tumors in 72 patients (56 men and 16 women; age 70.0 ± 11.6 years (range 31-94); mean tumor size 2.1 ± 1.2 cm [range 0.2-9]) who underwent lung RFA between June 2000 and May 2009. Mean follow-up periods for patients and tumors were 14 and 12 months, respectively. The local progression-free rate and survival rate were calculated to determine the contributing factors to local progression. During follow-up, 44 of 138 (32%) lung tumors showed local progression. The 1-, 2-, 3-, and 5-year overall local control rates were 61, 57, 57, and 38%, respectively. The risk factors for local progression were age (≥70 years), tumor size (≥2 cm), sex (male), and no achievement of roll-off during RFA (P < 0.05). Multivariate analysis identified tumor size ≥2 cm as the only independent factor for local progression (P = 0.003). For tumors <2 cm, 17 of 68 (25%) showed local progression, and the 1-, 2-, and 3-year overall local control rates were 77, 73, and 73%, respectively. Multivariate analysis identified that age ≥70 years was an independent determinant of local progression for tumors <2 cm in diameter (P = 0.011). The present study showed that 32% of lung tumors developed local progression after CT-guided RFA. The significant risk factor for local progression after RFA for lung tumors was tumor size ≥2 cm.

    Full Text Available This year PLOS Neglected Tropical Diseases (PLOS NTDs celebrates its tenth anniversary following the publication of the first issue in 2007 [1]. When PLOS NTDs was founded, the framework of the neglected tropical diseases (NTDs as an alternative to "other diseases" (as they were then referred to in the Millennium Development Goals was just getting started-especially for Africa [2, 3]. In the decade since, PLOS NTDs has overseen enormous successes in NTD control and elimination. Here, we want to briefly review the ten year progress made towards the control or elimination of the diseases now identified by the WHO as NTDs. Many of the details are highlighted in PLOS NTDs papers cited here, but the summary information is based on the recently released Global Burden of Disease (GBD Study 2015 (also launched with Gates Foundation support that summarized past-decade changes in disease prevalence, mortality, or disability rates (from the years 2005 to 2015 [4-6], as well as the GBD Study 2013 that summarizes disease prevalence changes over a longer time horizon from 1990 to 2013 [7].

    The Department of Defense (DoD)-United States Food and Drug Administration (FDA) shelf-life extension program (SLEP) was established in 1986 through an intra-agency agreement between the DoD and the FDA to extend the shelf life of product nearing expiry. During the early stages of development, special attention was paid to program operation, labeling requirements, and the cost benefits associated with this program. In addition to the substantial cost benefits, the program also provides the FDA's Center for Drug Evaluation and Research with significant scientific understanding and pharmaceutical resource. As a result of this unique resource, numerous regulatory research opportunities to improve public health present themselves from this distinctive scientific database, which includes examples of products shelf life, their long-term stability issues, and various physical and chemical tests to identify such failures. The database also serves as a scientific resource for mechanistic understanding and identification of test failures leading to the development of new formulations or more robust packaging. It has been recognized that SLEP is very important in maintaining both national security and public welfare by confirming that the stockpiled pharmaceutical products meet quality standards after the "expiration date" assigned by the sponsor. SLEP research is an example of regulatory science that is needed to best ensure product performance past the original shelf life. The objective of this article is to provide a brief history and background and most importantly the public health benefits of the SLEP. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association.

    To prospectively evaluate prognostic factors for new onset or progression of degenerative change on follow-up MRI one year after knee trauma and the association with clinical outcome. Within a prospective observational cohort study in general practice, we studied a subgroup of 117 patients with acute knee trauma (mean age 41 years, 43% women). Degenerative change was scored on MRI at baseline and after one year follow-up. Multivariate logistic regression analysis was performed to evaluate prognostic factors for new onset or progressive degenerative change on follow-up MRI. Association between new or progressive degeneration and clinical outcome after one year was assessed. On follow-up MRI 15% of patients with pre-existing knee osteoarthritis showed progression and 26% of patients demonstrated new degenerative change. The only statistically significant prognostic variable in the multivariate analysis was bone marrow oedema on initial MRI (OR 5.29 (95% CI 1.64-17.1), p = 0.005). A significant association between new or progressive degenerative change and clinical outcome was found (p = 0.003). Bone marrow oedema on MRI for acute knee injury is strongly predictive of new onset or progression of degenerative change of the femorotibial joint on follow-up MRI one year after trauma, which is reflected in clinical outcome.

    The aim of this study was to compare cognition, academic progress, behavior, and self-concept children of very low birth weight (VLBW, birth weight 2,499 g). At 14 years of age, 130 (84.4%) of 154 VLBW and 42 (70.0%) of 60 NBW children were assessed. Ten VLBW children and one NBW child who had cerebral palsy were excluded. VLBW children scored at a significantly lower level on all three composite scales of the Wechsler Intelligence Scale for Children, 3rd Edition. VLBW children were also significantly disadvantaged on more specific cognitive processes, including tests of visual processing and visual memory and on subtests reflecting learning and problem solving. Only in arithmetic was a difference between the groups discerned on tests of achievement. Significantly more VLBW children were rated by teachers as socially rejected and by their parents as having learning problems at school. VLBW children had significantly reduced self-esteem. VLBW children had more cognitive, academic, and behavioral problems and lower self-esteem at 14 years of age than NBW control subjects.

    To study the connection between parental myopia and their children's myopia from school age to adulthood. Two hundred and forty myopic schoolchildren (119 boys, 121 girls, mean age 10.9 years) with no previous spectacles for myopia were recruited to a 3-year treatment trial with different use of spectacles. Follow-ups were performed at mean ages of 13.9, 23.7 and 33.2 years for 238, 176 and 170 subjects respectively. Subjective refraction was calibrated to the spherical equivalent at corneal level (SEcor). Corneal refractive power (CR) and axial length (AL) were measured. Parental myopia was assessed with a questionnaire and the children assigned accordingly to one of three hereditary groups: both parents myopic H++, one myopic parent = H+- and no myopic parents = H-. At baseline, no significant gender differences in age or SEcor were found in the different hereditary groups. Among girls, CR was significantly higher in hereditary group H++ (45.20 ± 1.08 D) than in group H+- (44.19 ± 1.28 D; p = 0.006) or H- (43.84 ± 1.18 D; p parents were myopic and -3.19 ± 1.36 D if neither parent was myopic (p = 0.035), but no significant difference was observed in AL. The main difference between the hereditary groups was higher CR and myopic progression among females with myopic parents than non-myopic parents, but with no significant difference in AL with respect to parental myopia at study end. © 2016 Acta Ophthalmologica Scandinavica Foundation.

    Zoledronic acid 5 mg (ZOL) annually for 3 years reduces fracture risk in postmenopausal women with osteoporosis. To investigate long-term effects of ZOL on bone mineral density (BMD) and fracture risk, the Health Outcomes and Reduced Incidence with Zoledronic acid Once Yearly–Pivotal Fracture Trial (HORIZON-PFT) was extended to 6 years. In this international, multicenter, double-blind, placebo-controlled extension trial, 1233 postmenopausal women who received ZOL for 3 years in the core study were randomized to 3 additional years of ZOL (Z6, n = 616) or placebo (Z3P3, n = 617). The primary endpoint was femoral neck (FN) BMD percentage change from year 3 to 6 in the intent-to-treat (ITT) population. Secondary endpoints included other BMD sites, fractures, biochemical bone turnover markers, and safety. In years 3 to 6, FN-BMD remained constant in Z6 and dropped slightly in Z3P3 (between-treatment difference = 1.04%; 95% confidence interval 0.4 to 1.7; p = 0.0009) but remained above pretreatment levels. Other BMD sites showed similar differences. Biochemical markers remained constant in Z6 but rose slightly in Z3P3, remaining well below pretreatment levels in both. New morphometric vertebral fractures were lower in the Z6 (n = 14) versus Z3P3 (n = 30) group (odds ratio = 0.51; p = 0.035), whereas other fractures were not different. Significantly more Z6 patients had a transient increase in serum creatinine >0.5 mg/dL (0.65% versus 2.94% in Z3P3). Nonsignificant increases in Z6 of atrial fibrillation serious adverse events (2.0% versus 1.1% in Z3P3; p = 0.26) and stroke (3.1% versus 1.5% in Z3P3; p = 0.06) were seen. Postdose symptoms were similar in both groups. Reports of hypertension were significantly lower in Z6 versus Z3P3 (7.8% versus 15.1%, p < 0.001). Small differences in bone density and markers in those who continued versus those who stopped treatment suggest residual effects, and therefore, after 3 years of annual ZOL, many patients may discontinue

    We describe herein an autopsied case of multiple system atrophy (MSA) with prolonged clinical course of 18 years, and evaluate the extent of neurodegeneration and glial cytoplasmic inclusions (GCIs) in the entire brain of this rare case. A 64-year-old woman presented with typical neurological symptoms and imaging features of MSA. Thereafter, she became bedridden, and breathing was assisted through a tracheostomy for 12 years. She died at the age of 82 after 18 years from the initial symptom. Post mortem examination revealed severe neurodegeneration in the inferior olive, pontine nuclei, substantia nigra, locus ceruleus, putamen and cerebellum. Notably, phosphorylated α-synuclein (p-α-syn)-positive GCIs were found in these areas, but their number was very low. In contrast, the density of GCIs was much higher in such regions as the tectum/tegmentum of the brainstem, pyramidal tracts, neocortices and limbic system, which usually contain a small number of GCIs. Another constituent of GCIs, ubiquitin (Ub) and Ub-associated autophagy substrate p62, were also positive in some GCIs, and distribution of Ub/p62 immunoreactivity was proportionate to that of p-α-syn+ GCIs despite the very long duration of the disease. Furthermore, this case had complicated hypoxic encephalopathy, but p-α-syn+ GCIs were also found in the damaged white matter, indicating the contribution of α-syncleinopathy as well as hypoxic effect to the secondary myelin and axonal loss in the white matter. Together, this rare case suggests the contribution of the disease duration to the prevalence of GCIs, and the possible involvement of the limbic system in extensive-stage disease. © 2011 Japanese Society of Neuropathology.

    Rotavirus Efficacy and Safety Trial (REST) enrolled nearly 70,000 infants, of whom more than 23,000 were from Finland. REST determined the efficacy of the pentavalent rotavirus vaccine (RV5) against rotavirus-related hospitalisations and emergency department (ED) visits in the first year after vaccination. Finnish infants initially in REST transitioned into the Finnish Extension Study (FES), where they were followed for rotavirus-related hospitalisations and ED visits through their second year of life and beyond. FES identified 150 (31%) additional rotavirus gastroenteritis (RVGE) cases beyond those identified in REST in the Finnish participants. Overall, RV5 reduced RVGE hospitalisations and ED visits, regardless of the rotavirus serotype, by 93.8% (95% confidence interval [CI]: 90.8-95.9%) for up to 3.1 years following the last vaccine dose. Vaccine efficacy against combined hospitalisations and ED visits between ages 4 months to 11 months, 12 months to 23 months, and 24 months to 35 months was 93.9% (95% CI: 89.1-96.9%), 94.4% (95% CI: 90.2-97.0%), and 85.9% (95% CI: 51.6-97.2%), respectively. The reduction of hospitalisations and ED visits due to any acute gastroenteritis, rotavirus or not, was 62.4% (95% CI: 57.6-66.6%) over the entire follow-up period. The results from FES confirm that RV5 induces high and sustained protection against rotavirus-related hospitalisations and ED visits, and has a very substantial impact on all gastroenteritis-related hospitalisations and ED visits into the third year of life in Finnish children.

    Full Text Available The objective of this study was to determine whether treatment with the nonselective nonsteroidal anti-inflammatory drug (NSAID indomethacin slows cognitive decline in patients with Alzheimer's disease (AD.This double-blind, randomized, placebo-controlled trial was conducted between May 2000 and September 2005 in two hospitals in the Netherlands. 51 patients with mild to moderate AD were enrolled into the study. Patients received 100 mg indomethacin or placebo daily for 12 months. Additionally, all patients received omeprazole. The primary outcome measure was the change from baseline after one year of treatment on the cognitive subscale of the AD Assessment Scale (ADAS-cog. Secondary outcome measures included the Mini-Mental State Examination, the Clinician's Interview Based Impression of Change with caregiver input, the noncognitive subscale of the ADAS, the Neuropsychiatric Inventory, and the Interview for Deterioration in Daily life in Dementia. Considerable recruitment problems of participants were encountered, leading to an underpowered study. In the placebo group, 19 out of 25 patients completed the study, and 19 out of 26 patients in the indomethacin group. The deterioration on the ADAS-cog was less in the indomethacin group (7.8+/-7.6, than in the placebo group (9.3+/-10.0. This difference (1.5 points; CI -4.5-7.5 was not statistically significant, and neither were any of the secondary outcome measures.The results of this study are inconclusive with respect to the hypothesis that indomethacin slows the progression of AD.

    Full Text Available Abstract Objectives To evaluate the efficacy of a conservative treatment to prevent the progression of caries using an infiltrant on non-cavitated pit and fissures. Material and Methods This controlled clinical trial selected 23 volunteers with clinically and radiographically non-cavitated occlusal caries among patients presenting a “rather low” to “very high” caries risk. Eighty-six teeth were randomly divided into two experimental groups: teeth receiving a commercial pit-and-fissure sealant (Alpha Seal-DFL and contralateral teeth receiving Icon infiltrant (DMG. Caries progression was monitored by clinical (laser fluorescence caries detection and radiographic examination at 12-month intervals over a period of 3 years of monitored caries progression. Probing the sealing materials to detect areas of retention was also used to evaluate marginal integrity. Results Statistical analysis showed no difference in caries progression using laser fluorescence caries detection when both materials were compared, regardless of the evaluation times (p>0.05. No significance was observed when the marginal sealant integrity of both materials was compared, regardless of the evaluation time (p0.05. SEM analysis exhibited a more homogeneous sealing for the infiltrant than obtained by the sealant. Conclusions The infiltrant was effective to prevent the caries progression in non-cavitated pit-and-fissures after 3 years of clinical evaluation, comparable with the conventional sealant. The infiltrant also presented better results in terms of caries progression at the 3-year evaluation time using the radiographic analysis.

    Background A previous fibromyalgia (FM) research reports that 20%–47% of diagnosed patients may not meet the study definition of FM 1–2 years after diagnosis. The aim of this study was to gain a better understanding of the progression of FM in a geographically diverse cohort over a 2-year time period. Methods This cohort study followed 226 subjects recruited online to assess FM and chronic widespread pain (CWP) diagnosis stability over time. At enrollment (baseline), subjects provided informed consent, completed an online questionnaire consisting of the London Fibromyalgia Epidemiology Study Screening Questionnaire to screen for CWP (bilateral pain above/below waist lasting ≥1 week in the past 3 months), visited a site for physician evaluation for FM, and completed a questionnaire with validated patient-reported outcome instruments. Subjects were classified into mutually exclusive groups: FM+CWP+ (screened positive for CWP and received physician diagnosis of FM), FM−CWP+ (screened positive for CWP but did not receive physician diagnosis of FM), and FM−CWP− (screened negative for CWP). Approximately 2 years later (follow-up), subjects were reassessed at the same study site and completed a questionnaire with the same patient-reported outcomes. Results Seventy-six FM+CWP+ subjects completed assessments at both time points; 56 (73.7%) met the FM study definition at follow-up. Twenty subjects no longer met the FM study definition (eleven became FM−CWP− and nine became FM−CWP+). Ten subjects (two from FM−CWP− and eight from FM−CWP+) transitioned into the FM+CWP+ group at follow-up; they reported more tender points and pain interference with sleep and worse physical function at baseline compared with subjects who did not transition to FM+CWP+. Most (76.7%) of the subjects who transitioned into/out of FM+CWP+ experienced changes in CWP, number of positive tender points, or both. Conclusion The results suggest that some FM+CWP+ patients experience

    The purpose of this study was to determine the institutional trajectory and future of young children in child welfare. A catamnestic study - based on data from the child welfare office in Maine and Loire, France, from 1994 to 2001 - was conducted by a child psychiatrist and a psychologist. Medical, judicial, and educational data (development, health, pathways in child protection services) were collected and analyzed regarding the status of these children 15 years later, adding information gathered by interviewing the child welfare and foster family consultant. We included 128 children admitted to the child welfare office before 4 years of age. Admission to the child welfare system suffers from care delays (a mean of 13.1 months between the first child protection referral and placement) with an average entry age of 17 months and frequent cases of child abuse (e.g., seven Silverman syndrome cases). The physical and mental health status of these children was poor (poorly monitored pregnancies, prematurity, low birth weight). More than one third of the children had growth failure at admission, with catch-up in half of the cases. The average length of stay in the child welfare system was 13.2±4.6 years. At the end of the follow-up, there were specific measures to safeguard vulnerable adults: "young adult" (24 cases), "major protection" (eight cases) and "disabled living allowance" (nine cases). One hundred and sixteen children suffered from psychiatric disorders at entry and 98 at the end. The general functioning of children as assessed by the Children's Global Assessment Scale (CGAS) showed a statistically significant improvement. One out of two young adults showed problems integrating socially with chaotic pathways: many foster placements, unsuccessful return to the family, and academic failures. The clinical situations of children in the child welfare office and their long-term progression confirm the importance of this public health problem. Although the measures

    The computational fluid dynamics (CFD) and computational structural mechanics (CSM) focus areas at Argonne's Transportation Research and Analysis Computing Center (TRACC) initiated a project to support and compliment the experimental programs at the Turner-Fairbank Highway Research Center (TFHRC) with high performance computing based analysis capabilities in August 2010. The project was established with a new interagency agreement between the Department of Energy and the Department of Transportation to provide collaborative research, development, and benchmarking of advanced three-dimensional computational mechanics analysis methods to the aerodynamics and hydraulics laboratories at TFHRC for a period of five years, beginning in October 2010. The analysis methods employ well-benchmarked and supported commercial computational mechanics software. Computational mechanics encompasses the areas of Computational Fluid Dynamics (CFD), Computational Wind Engineering (CWE), Computational Structural Mechanics (CSM), and Computational Multiphysics Mechanics (CMM) applied in Fluid-Structure Interaction (FSI) problems. The major areas of focus of the project are wind and water effects on bridges - superstructure, deck, cables, and substructure (including soil), primarily during storms and flood events - and the risks that these loads pose to structural failure. For flood events at bridges, another major focus of the work is assessment of the risk to bridges caused by scour of stream and riverbed material away from the foundations of a bridge. Other areas of current research include modeling of flow through culverts to assess them for fish passage, modeling of the salt spray transport into bridge girders to address suitability of using weathering steel in bridges, CFD analysis of the operation of the wind tunnel in the TFCHR wind engineering laboratory, vehicle stability under high wind loading, and the use of electromagnetic shock absorbers to improve vehicle stability

    Comprehensive data on drug-resistant patterns of Acinetobacter baumannii isolates in developing countries is limited. We conducted a multihospital study to assess the rate and trend of drug-resistant phenotypes in Ac. baumannii using standardized definitions and to determine the remaining therapeutic options against resistant phenotypes. The 401 nonduplicate isolates were collected from six hospitals which are geographically distributed across Tehran, Iran over a 3-year period. Following PCR of bla OXA -51-like gene, susceptibility testing was performed against nine antimicrobial agent categories. Three hundred and ninety (97%) isolates were resistant to least two carbapenems; carbapenem-resistant Ac. baumannii. The majority of isolates (366, 91·3%) were extensively drug resistant (XDR) and the rest of the isolates were classified as multidrug resistant (26, 6·8%) and susceptible (9, 2·2%). The rate of XDR-AB slightly decreased from 93·8% in 2011 to 89·8% in 2013. A considerable decrease in resistance to doxycycline, minocycline and tigecycline was demonstrated. The XDR-AB isolates showed susceptibility to gentamicin (10·4%), tobramycin (23%), ampicilin-sulbactam (30·1%), minocycline (32·8%), tigecycline (10·7%), doxycycline (21·6%), colistin (100%) and polymixin B (100%). We demonstrated the rising trend of resistance to all antibiotic categories except tetracyclines and folate pathway inhibitors. We found that the treatment options against XDR-AB are extremely limited and each treatment alternative including even old, but safe, antibiotics might be considered. The high frequency of drug-resistant phenotypes including carbapenem-resistant Acinetobacter baumannii, multidrug-resistant, and extensively resistant has been demonstrated in Ac. baumannii isolates tested here. As the antibiotic resistance pattern of isolates varies in different geographical regions, this study can provide comprehensive information about the antibiotic resistance profile of Ac

    Full Text Available Introduction. Multiple sclerosis (MS is an immunemediated disease of the central nervous system that affects young individuals and leads to severe disability. High dose immunoablation followed by autologous hemopoietic stem cell transplantation (AHSCT has been considered in the last 15 years as potentialy effective therapeutic approach for agressive MS. The most recent long-time follow-up results suggest that AHSCT is not only effective for highly aggressive MS, but for relapsing-remitting MS as well, providing long-term remission, or maybe even cure. We presented a 10- year follow-up of the first MS patient being treated by immunoablation therapy and AHSCT. Case report. A 27-year-old male experienced the first symptoms - intermitent numbness and paresthesia of arms and legs of what was treated for two years by psychiatrist as anxiety disorder. After he developed severe paraparesis he was admitted to the Neurology Clinic and diagnosed with MS. Our patient developed aggressive MS with frequent relapses, rapid disability progression and transition to secondary progressive form 6 years after MS onset [the Expanded Disability Status Scale (EDSS 7.0 Ambulation Index (AI 7]. AHSCT was performed, cyclophosphamide was used for hemopoietic stem cell mobilization and the BEAM protocol was used as conditionig regimen. No major adverse events followed the AHSCT. Neurological impairment improved, EDSS 6.5, AI 6 and during a 10-year followup remained unchanged. Brain MRI follow-up showed the absence of gadolinium enhancing lesions and a mild progression of brain atrophy. Conclusion. The patient with rapidly evolving, aggressive, noninflammatory MS initialy improved and remained stable, without disability progression for 10 years, after AHSCT. This kind of treatment should be considered in aggressive MS, or in disease modifying treatment nonresponsive MS patients, since appropriately timed AHSCT treatment may not only prevent disability progression but reduce

    The nuclear power industry's addressing of life extension is a natural trend in the maturation of this technology after 20 years of commercial operation. With increasing emphasis on how plants are operated, and less on how to build them, attention is turning on to maximizing the use of these substantial investments. The first studies of life extension were conducted in the period from 1978 and 1982. These were motivated by the initiation, by the Nuclear Regulatory Commission (NRC), of studies to support decommissioning rulemaking. The basic conclusions of those early studies that life extension is feasible and worth pursuing have not been changed by the much more extensive investigations that have since been conducted. From an engineering perspective, life extension for nuclear plants is fundamentally the same as for fossil plants

    To evaluate the longterm safety and efficacy of subcutaneous tocilizumab (TCZ-SC) as monotherapy in patients with rheumatoid arthritis (RA). Of 346 patients who received 24 weeks of double-blind treatment with either TCZ-SC monotherapy, 162 mg every 2 weeks (q2w); or intravenous TCZ (TCZ-IV) monotherapy, 8 mg/kg every 4 weeks; 319 patients continued to receive TCZ-SC q2w in the 84-week open-label extension (OLE) of the MUSASHI study (JAPICCTI-101117). Efficacy, safety, and immunogenicity were evaluated for all patients treated with TCZ during 108 weeks. The proportions of patients who achieved American College of Rheumatology 20/50/70 responses, low disease activity [28-joint Disease Activity Score (DAS28) ≤ 3.2], or remission (DAS28 < 2.6) at Week 24 were maintained until Week 108. The incidences of adverse events and serious adverse events were 498.3 and 16.9 per 100 patient-years (PY), respectively. The overall safety of TCZ-SC monotherapy was similar to that of TCZ-IV monotherapy. Rates of injection site reactions (ISR) through 108 weeks remained similar to rates through 24 weeks. ISR were mild and did not cause any patient withdrawals. No serious hypersensitivity events (including anaphylactic reactions) occurred. Anti-TCZ antibodies were present in 2.1% of patients treated with TCZ-SC monotherapy. TCZ-SC monotherapy maintained a favorable safety profile and consistent efficacy throughout the 108-week study. Like TCZ-IV, TCZ-SC could provide an additional treatment option for patients with RA.

    2011-01-01

    The Co-operative Programme for the Exchange of Scientific and Technical Information Concerning Nuclear Installation Decommissioning (CPD) is a joint undertaking according to Article 5 of the Statute of the NEA. Concluded in 1985, the Agreement constituting the CPD has been continuously extended, although modified in 2003, with the current programme period lasting until the end of 2013. This report provides information about the participants, structure and achievements of the Co-operative Programme and the projects involved. The projects in the Programme have a broad range of characteristics and cover various types of reactors and fuel facilities. The number of projects in the programme has grown from 42 to 59 over the past five years. The Programme now covers 35 reactor related projects and 24 fuel related projects representing a wide selection of facility types in each category. Also, all phases of decommissioning - from active dismantling to safe store and to completed decommissioning back to 'green field conditions' - are represented. Over the 25 years of experience of the Co-operative Programme on Decommissioning, and in particular through the information exchange and review within the TAG, it has become evident that: - decommissioning can and has been done in a safe, cost-effective and environmentally friendly manner; - the evolution of technologies have demonstrated their effectiveness in performance improvements in all aspects of conducting decommissioning projects; - the upkeep and maintenance of design, construction and operational records can significantly enhance performance through all stages of a decommissioning project; - in the absence of waste disposal facilities, interim waste storage facilities with integrated waste processing facilities can effectively be used to keep all levels of waste streams moving and avoid delays to project schedules; - cleanup of material for recycle and reuse or disposal as conventional waste is cost

    Overt and subclinical hypothyroidism are risk factors for atherosclerosis and cardiovascular diseases. It is unclear whether thyroid hormone levels within the normal range are also associated with atherosclerosis measured by coronary artery calcium (CAC). This study aimed to examine the relationship between normal variations in thyroid function and changes in CAC. We conducted a 4-year retrospective study of 2173 apparently healthy men and women with normal thyroid hormone levels. Their free thyroxin (FT4), free triiodothyronin (FT3) and thyroid-stimulating hormone (TSH) levels were measured by electrochemiluminescent immunoassay. The CAC score (CACS) of each subject was measured by multidetector computed tomography in both 2010 and 2014. Progression of CAC was defined as a CACS change over 4 years > 0. The mean CACS changes over 4 years by quartiles of baseline FT4 level (lowest to highest) were 12·9, 8·43, 7·82 and 7·81 (P = 0·028). CAC progression was not significantly associated with either the baseline FT3 or TSH levels. The odds ratios (OR) for CAC progression over 4 years (highest vs lowest quartile for baseline FT4) were 0·647 (95% confidence interval (CI) 0·472-0·886) after adjustment for confounding factor, which were attenuated with further adjustment for lipid profiles, homoeostasis model assessment of insulin resistance, high-sensitivity C-reactive protein and hypertension [0·747 (95% CI 0·537-1·038)]. Quartiles of baseline FT3 or TSH level did not show any increased OR for CAC progression after adjustment for confounding factors. In this cohort of euthyroid men and women, a low baseline FT4 level was associated with a high risk of CACS progression over 4 years. © 2015 John Wiley & Sons Ltd.

    Green roofs can be an attractive strategy for adding perviousness in dense urban environments where rooftops are a high fraction of the impervious land area. As a result, green roofs are being increasingly implemented as part of urban stormwater management plans in cities around the world. In this study, three full-scale green roofs in New York City (NYC) were monitored, representing the three extensive green roof types most commonly constructed: (1) a vegetated mat system installed on a Columbia University residential building, referred to as W118; (2) a built-in-place system installed on the United States Postal Service (USPS) Morgan general mail facility; and (3) a modular tray system installed on the ConEdison (ConEd) Learning Center. Continuous rainfall and runoff data were collected from each green roof between June 2011 and June 2012, resulting in 243 storm events suitable for analysis ranging from 0.25 to 180 mm in depth. Over the monitoring period the W118, USPS, and ConEd roofs retained 36%, 47%, and 61% of the total rainfall respectively. Rainfall attenuation of individual storm events ranged from 3 to 100% for W118, 9 to 100% for USPS, and 20 to 100% for ConEd, where, generally, as total rainfall increased the per cent of rainfall attenuation decreased. Seasonal retention behavior also displayed event size dependence. For events of 10–40 mm rainfall depth, median retention was highest in the summer and lowest in the winter, whereas median retention for events of 0–10 mm and 40 +mm rainfall depth did not conform to this expectation. Given the significant influence of event size on attenuation, the total per cent retention during a given monitoring period might not be indicative of annual rooftop retention if the distribution of observed event sizes varies from characteristic annual rainfall. To account for this, the 12 months of monitoring data were used to develop a characteristic runoff equation (CRE), relating runoff depth and event size, for each

Continuous rainfall and runoff data were collected from each green roof between June 2011 and June 2012, resulting in 243 storm events suitable for analysis ranging from 0.25 to 180 mm in depth. Over the monitoring period the W118, USPS, and ConEd roofs retained 36%, 47%, and 61% of the total rainfall respectively. Rainfall attenuation of individual storm events ranged from 3 to 100% for W118, 9 to 100% for USPS, and 20 to 100% for ConEd, where, generally, as total rainfall increased the per cent of rainfall attenuation decreased. Seasonal retention behavior also displayed event size dependence. For events of 10-40 mm rainfall depth, median retention was highest in the summer and lowest in the winter, whereas median retention for events of 0-10 mm and 40 +mm rainfall depth did not conform to this expectation. Given the significant influence of event size on attenuation, the total per cent retention during a given monitoring period might not be indicative of annual rooftop retention if the distribution of observed event sizes varies from characteristic annual rainfall. To account for this, the 12 months of monitoring data were used to develop a characteristic runoff equation (CRE), relating runoff depth and event size, for each

    The subcortical deep gray matter (DGM) develops selective, progressive, and clinically relevant atrophy in progressive forms of multiple sclerosis (PMS). This patient population is the target of active neurotherapeutic development, requiring the availability of outcome measures. We tested a fully automated MRI analysis pipeline to assess DGM atrophy in PMS. Consistent 3D T1-weighted high-resolution 3T brain MRI was obtained over one year in 19 consecutive patients with PMS [15 secondary progressive, 4 primary progressive, 53% women, age (mean±SD) 50.8±8.0 years, Expanded Disability Status Scale (median, range) 5.0, 2.0-6.5)]. DGM segmentation applied the fully automated FSL-FIRST pipeline ( http://fsl.fmrib.ox.ac.uk ). Total DGM volume was the sum of the caudate, putamen, globus pallidus, and thalamus. On-study change was calculated using a random-effects linear regression model. We detected one-year decreases in raw [mean (95% confidence interval): -0.749 ml (-1.455, -0.043), p = 0.039] and annualized [-0.754 ml/year (-1.492, -0.016), p = 0.046] total DGM volumes. A treatment trial for an intervention that would show a 50% reduction in DGM brain atrophy would require a sample size of 123 patients for a single-arm study (one-year run-in followed by one-year on-treatment). For a two-arm placebo-controlled one-year study, 242 patients would be required per arm. The use of DGM fraction required more patients. The thalamus, putamen, and globus pallidus, showed smaller effect sizes in their on-study changes than the total DGM; however, for the caudate, the effect sizes were somewhat larger. DGM atrophy may prove efficient as a short-term outcome for proof-of-concept neurotherapeutic trials in PMS.

    The EINSTEIN-Extension trial (EINSTEIN-EXT) found that continued treatment with rivaroxaban for an additional 6 or 12 months (vs placebo) after 6-12 months of initial anticoagulation significantly reduced the risk of recurrent venous thromboembolism (VTE) with a small non-significant increased risk of major bleeding (none fatal or in critical site). This study aimed to compare total healthcare cost between rivaroxaban and placebo, based on the EINSTEIN-EXT event rates. Total healthcare cost was calculated as the sum of treatment and clinical event costs from a US managed care perspective. Treatment duration and event rates were obtained from the EINSTEIN-EXT study. Adjustment on treatment duration was made by assuming a 10% non-adherence rate. Drug costs were based on wholesale acquisition costs. Cost estimates for clinical events (i.e. recurrent deep vein thrombosis [DVT], recurrent pulmonary embolism, major bleeding, clinically relevant non-major bleeding) were determined from the literature. Results were examined over a ±20% range of each cost component and over 95% confidence intervals (CIs) of event rate differences in deterministic (one-way) and probabilistic sensitivity analyses (PSA). Total healthcare cost was $1,454 lower for rivaroxaban-treated (vs placebo-treated) patients in the base-case, with a lower clinical event cost fully offsetting drug cost. The cost savings of recurrent DVT alone (-$3,102) was greater than drug cost ($2,723). Total healthcare cost remained lower for rivaroxaban in the majority (73%) of PSA (cost difference [95% CI] = -$1,454 [-$2,396, $1,231]). This study was conducted over the 1-year observation period of the EINSTEIN-EXT trial, which limited "real-world" applicability and examination of long-term economic impact. Assumptions on drug and clinical event costs were US-based and, thus, not applicable to other healthcare systems. Total healthcare costs were estimated to be lower for patients continuing rivaroxaban therapy

    To investigate the association between circulating oxidized low-density lipoprotein (ox-LDL) levels and progression of subclinical atherosclerosis and to examine whether this link is independent of other low-density lipoprotein (LDL)-related parameters. Totally, 804 subjects who were free of cardiovascular disease at baseline completed risk factor surveys and carotid ultrasound measurements in 2002 and 2012. Modified Poisson regression was performed to examine the association between baseline serum ox-LDL levels and the 10-year risk of progression of carotid atherosclerosis which was defined as the development of at least one new plaque in a previously plaque-free carotid segment at re-examination. The mean age of the subjects was 58.6±7.7 years at baseline and 43.3% were men. A total of 504 (62.7%) subjects had carotid plaque progression at re-examination. Subjects in the intermediate and highest tertiles of ox-LDL had a significantly higher adjusted risk of atherosclerosis progression than those in the lowest tertile [relative risk (95% confidence interval) 1.17 (1.01-1.34) for the intermediate tertile and 1.23 (1.07-1.42) for the highest tertile]. This association was independent of baseline levels of LDL-C, total LDL particle number, and small LDL particle number. This study demonstrates that serum ox-LDL levels predict 10-year progression of subclinical atherosclerosis. Moreover, this effect is independent of the cholesterol content, the number, and the size of LDL particles.

    There are few data on the incidence rates of diabetes and prediabetes (dysglycemia) in Asian Indians. This article presents the incidence of diabetes and prediabetes and the predictors of progression in a population-based Asian Indian cohort. Data on progression to diabetes and prediabetes from 1,376 individuals, a subset of 2,207 of the Chennai Urban Rural Epidemiology Study (CURES) cohort (phase 3) with normal glucose tolerance (NGT) or prediabetes at baseline, who were followed for a median of 9.1 years (11,629 person-years), are presented. During follow-up, 534 died and 1,077 with NGT and 299 with prediabetes at baseline were reinvestigated in a 10-year follow-up study. Diabetes and prediabetes were diagnosed based on the American Diabetes Association criteria. Incidence rates were calculated and predictors of progression to prediabetes and/or diabetes were estimated using the Cox proportional hazards model. The incidence rates of diabetes, prediabetes, and "any dysglycemia" were 22.2, 29.5, and 51.7 per 1,000 person-years, respectively. Among those with NGT, 19.4% converted to diabetes and 25.7% to prediabetes, giving an overall conversion rate to dysglycemia of 45.1%. Among those with prediabetes, 58.9% converted to diabetes. Predictors of progression to dysglycemia were advancing age, family history of diabetes, 2-h plasma glucose, glycated hemoglobin (HbA1c), low HDL cholesterol, and physical inactivity. Asian Indians have one of the highest incidence rates of diabetes, with rapid conversion from normoglycemia to dysglycemia. Public health interventions should target modifiable risk factors to slow down the diabetes epidemic in this population. © 2015 by the American Diabetes Association.

    Progress during this reporting period has been in several areas. The research effort has continued in close collaboration with personnel at LBL and LLNL. In addition, studies of the longitudinal physics, which are jointly supported by the Division of High Energy Physics of the U.S. Department of Energy, have benefitted from collaboration with personnel at the University of Maryland associated with the Maryland transport experiment. The research results supported by this program have been, and will be, actively reported to the scientific community through papers presented at conferences and published in conference proceedings as well as in the refereed literature. The first of these references describe work primarily supported under the current contract, while the remaining references describe work jointly supported by the Division of High Energy Physics. Progress detailed in these manuscripts, currently in preparation, will be included in a later report. The emphasis below is instead concentrated on reporting work, in cooperation with LBL, on the simulation of large aperture quadrupoles, with a further emphasis on the NRL contribution. This work is concentrated on understanding the basic nonlinear physics which is important to the design of large aperture magnetic quadrupoles, as well as the numerical requirements for reliable simulations of that physics. In particular, comparisons between the SHIFT-XY and HIFI simulation codes are presented to determine the conditions under which the HIFI code, which is faster running, but is generally run using less accuracy in the space charge model than SHIFT-XY, can be appropriately employed

    Oak tree rings from Southern Germany covering the AD 1010-1110 years have been analyzed for radiocarbon with accelerator mass spectrometry (AMS) at the laboratory at ETH Zurich. High-precision measurements with a precision down to 12 years radiocarbon age and a time resolution of 2 years aimed to identify modulations of the {sup 14}C concentration in tree ring samples caused by the 11 years solar cycles, a feature that so far is not visible in the IntCal calibration curve. Our results are in good agreement with the current calibration curve IntCal09. However, we observed an offset in radiocarbon age of 25-40 years towards older values. An evaluation of our sample preparation, that included variations of e.g.: chemicals, test glasses and processing steps did not explain this offset. The numerous measurements using the AMS-MICADAS system validated its suitability for high precision measurements with high repeatability.

    To assess the 5-year progression of erosions and joint space narrowing (JSN) and their associations with rheumatoid factor (RF) status in 2 large, multicenter, early rheumatoid arthritis cohorts, spanning 25 years. Radiographic joint damage was recorded using the Sharp/van der Heijde (SHS) method in the Early Rheumatoid Arthritis Study (ERAS), 1986-2001, and the Early Rheumatoid Arthritis Network (ERAN), 2002-2013. Mixed-effects negative binomial regression estimated changes in radiographic damage over 5 years, including erosions and JSN, separately. RF, along with age, sex, and baseline markers of disease activity were controlled for. A total of 1,216 patients from ERAS and 446 from ERAN had radiographic data. Compared to ERAS, ERAN patients had a lower mean total SHS score at baseline (ERAN 6.2 versus ERAS 10.5; P < 0.001) and mean annual rate of change (ERAN 2.5 per year versus ERAS 6.9 per year; P < 0.001). Seventy-four percent of ERAS and 27% of ERAN patients progressed ≥5 units. Lower scores at baseline in ERAN were largely driven by reductions in JSN (ERAS 3.9 versus ERAN 1.2; P < 0.001), along with erosions (ERAS 1.9 versus ERAN 0.8; P < 0.001). RF was associated with greater progression in each cohort, but the absolute difference in mean annual rate of change for RF-positive patients was substantially higher for ERAS (RF positive 8.6 versus RF negative 5.1; P < 0.001), relative to ERAN (RF positive 2.0 versus RF negative 1.9; P = 0.855). Radiographic progression was shown to be significantly reduced between the 2 cohorts, and was associated with lower baseline damage and other factors, including changes in early disease-modifying antirheumatic drug use. The impact of RF status as a prognostic marker of clinically meaningful change in radiographic progression has markedly diminished in the context of more modern treatment. © 2017, American College of Rheumatology.

  16. Natalizumab Significantly Improves Cognitive Impairment over Three Years in MS: Pattern of Disability Progression and Preliminary MRI Findings.

    Directory of Open Access Journals (Sweden)

    Flavia Mattioli

    Full Text Available Previous studies reported that Multiple Sclerosis (MS patients treated with natalizumab for one or two years exhibit a significant reduction in relapse rate and in cognitive impairment, but the long term effects on cognitive performance are unknown. This study aimed to evaluate the effects of natalizumab on cognitive impairment in a cohort of 24 consecutive patients with relapsing remitting MS treated for 3 years. The neuropsychological tests, as well as relapse number and EDSS, were assessed at baseline and yearly for three years. The impact on cortical atrophy was also considered in a subgroup of them, and are thus to be considered as preliminary. Results showed a significant reduction in the number of impaired neuropsychological tests after three years, a significant decrease in annualized relapse rate at each time points compared to baseline and a stable EDSS. In the neuropsychological assessment, a significant improvement in memory, attention and executive function test scores was detected. Preliminary MRI data show that, while GM volume did not change at 3 years, a significantly greater parahippocampal and prefrontal gray matter density was noticed, the former correlating with neuropsychological improvement in a memory test. This study showed that therapy with Natalizumab is helpful in improving cognitive performance, and is likely to have a protective role on grey matter, over a three years follow-up.

  17. Ultraviolet Extensions

    Science.gov (United States)

    2008-01-01

    [figure removed for brevity, see original site] Side-by-Side Comparison Click on image for larger view This ultraviolet image from NASA's Galaxy Evolution Explorer shows the Southern Pinwheel galaxy, also know as Messier 83 or M83. It is located 15 million light-years away in the southern constellation Hydra. Ultraviolet light traces young populations of stars; in this image, young stars can be seen way beyond the main spiral disk of M83 up to 140,000 light-years from its center. Could life exist around one of these far-flung stars? Scientists say it's unlikely because the outlying regions of a galaxy are lacking in the metals required for planets to form. The image was taken at scheduled intervals between March 15 and May 20, 2007. It is one of the longest-exposure, or deepest, images ever taken of a nearby galaxy in ultraviolet light. Near-ultraviolet light (or longer-wavelength ultraviolet light) is colored yellow, and far-ultraviolet light is blue. What Lies Beyond the Edge of a Galaxy The side-by-side comparison shows the Southern Pinwheel galaxy, or M83, as seen in ultraviolet light (right) and at both ultraviolet and radio wavelengths (left). While the radio data highlight the galaxy's long, octopus-like arms stretching far beyond its main spiral disk (red), the ultraviolet data reveal clusters of baby stars (blue) within the extended arms. The ultraviolet image was taken by NASA's Galaxy Evolution Explorer between March 15 and May 20, 2007, at scheduled intervals. Back in 2005, the telescope first photographed M83 over a shorter period of time.

    Atherosclerosis and osteoporosis are chronic diseases that progress with age, and studies suggest aortic calcification, an indicator of atherosclerosis, is inversely associated with bone mineral density (BMD). The osteoprotegerin (OPG)/receptor activator of NF-κB (RANK)/RANK ligand (RANKL) system has been proposed as a shared regulatory system for bone and vasculature. Denosumab (DMAb), a monoclonal antibody against RANKL, improved BMD and reduced fracture risk in the Fracture Reduction Evaluation of Denosumab in Osteoporosis Every 6 Months (FREEDOM) trial. We evaluated whether or not treatment with DMAb influenced progression of aortic calcification (AC) and incidence of cardiovascular (CV) adverse events. We included 2363 postmenopausal women with osteoporosis (1142 placebo, 1221 DMAb), selected from 7808 participants in the FREEDOM trial (3906 placebo, 3902 DMAb), at high risk of CV events according to modified Raloxifene Use for the Heart (RUTH) criteria. CV adverse events were reported by participants. AC scores were assessed using a semiquantitative method from lateral spine X-rays. Change in AC score from baseline to 12 (n = 1377), 24 (n = 1231), and 36 months (n = 1045) was calculated as AC score at follow-up minus AC score at baseline. AC progression was defined as change in AC score >0. Baseline characteristics, CV risk factors, and AC scores were similar between treatment groups. Mean age of participants was 74 years (range, 60-90), 88% were white, and 77% had AC score >0 at baseline. Frequency of AC progression over 3 years did not differ between women in placebo (22%) and DMAb (22%) groups (p = 0.98). AC progression did not differ between treatment groups when analyzed by baseline estimated glomerular filtration rate or by baseline AC scores. Frequency of CV adverse events did not differ between placebo (40%) and DMAb (38%) groups (p = 0.26). In conclusion, DMAb treatment had no effect on progression of AC or incidence of CV

    Basic research and our previous studies have suggested that mercury exposure enhances lipid peroxidation and the risk of myocardial infarction, but there are no studies concerning the association between mercury accumulation and atherosclerosis. We therefore investigated whether high hair mercury content is associated with accelerated progression of carotid atherosclerosis, determined by ultrasonographic assessment of common carotid intima-media thickness (IMT), in a prospective study among 1014 men aged 42-60 years. In a linear regression model adjusting for other atherosclerotic risk factors, high hair mercury content was one of the strongest predictors of the 4-year increase in the mean IMT (P2.81 microg/g (fifths) had an IMT increase of 0.105, 0.102, 0.113, 0.107 and 0.140 mm/4 years, respectively (P=0.041 for heterogeneity between groups). The IMT increase was 0.034 mm/4 years (31.9%) greater in the highest fifth than in the other fifths (P<0.05 for the difference). These findings suggest that mercury accumulation in the human body is associated with accelerated progression of carotid atherosclerosis.

    The Refining and Conversion Facility located in the Ningyo-toge Environmental Engineering Center. Process of natural uranium conversion facility (PNC Process) and reprocessed uranium conversion facility (two-stage dry fluorination system) is in a Refining and Conversion Facility. This building started construction in 1979 and was completed in October 1981. The PNC process operated from March 1982 to March 1991. As a result, uranium hexafluoride of about 385 tonU was manufactured. Also, the reprocessed uranium conversion process operated from December 1982 to July 1999. As a result, uranium hexafluoride of about 338 tonU was manufactured. The demonstration of the demolition method was done using the PNC process after the end of operation. The schedule which will finish dismantling of all equipment in a radiation controlled area is by the 2011 fiscal year. This report summarized the present situation by the first half of the 2008 fiscal year of a Refining and Conversion Facility decommissioning. (author)

    The safety and effectiveness of natalizumab in patients with relapsing-remitting multiple sclerosis (RRMS) has been demonstrated in clinical trials. However, due to the limitations of these trials, it is important to know how the condition behaves under long-term clinical practice conditions. To determine the long-term effectiveness of natalizumab in patients with RRMS by means of annual evaluation of the "no evidence of disease activity" (NEDA) parameter, which includes number of relapses, disability (measured with the Expanded Disability Status Scale), and brain MRI parameters. We performed a retrospective study of patients with RRMS from 3 centres who were treated with one or more doses of natalizumab. Each year, we evaluated NEDA status and safety based on the percentage of patients who discontinued treatment with natalizumab and experienced adverse reactions. The study included 89 patients, most of whom received treatment for 2 to 4 years, with a follow-up period of up to 7 years. Natalizumab significantly reduces the radiological and clinical progression of the disease, as well as the annual rate of relapses. The NEDA parameter demonstrates the effectiveness of the drug, with values of 75.28% for year one and 66.67% for year 7. Twenty-five patients (28.1%) dropped out after a median of 4 years. Fourteen of these patients (56%) dropped out due to the appearance of anti-JC virus antibodies, either in isolation or associated with another cause. Four dropouts (16%) were due to treatment ineffectiveness, with one patient dying due to progressive multifocal leukoencephalopathy. Natalizumab is highly effective as measured by the NEDA long-term remission parameter. Copyright © 2018 Sociedad Española de Neurología. Publicado por Elsevier España, S.L.U. All rights reserved.

    Limited information exists regarding the natural progression of health-related quality of life (HRQOL) in the general population, as most research has been cross-sectional or has followed populations with specific medical conditions. Such norms are important to establish, because the effect of any intervention may be confounded by changes due to the natural progression of HRQOL over time. Participants were randomly selected from 9 Canadian cities and surrounding rural areas. Changes in the eight domains and 2 summary component scores of the Medical Outcomes Study 36-item short form (SF-36) were examined over a 5 year period (1996/1997-2001/2002). Mean changes were calculated for men and women within 10 year age categories. Multiple imputation was used to adjust for potential selection bias due to missing data. The baseline sample included 6539 women and 2884 men. Loss to follow-up was 17% for women and 23% for men. Mean changes tended to be small, but there was an overall trend towards decreasing HRQOL over time. Changes were more pronounced in the older age groups and in the physically oriented domains. Younger age groups tended towards small mean improvements, particularly in the mentally oriented domains. Large standard errors suggest that on an individual level, large improvements in some participants are balanced by large declines in others. In general, the HRQOL of Canadians appears relatively stable over a 5 year period. However, care should be taken when assessing HRQOL longitudinally in certain age or gender groups, as changes associated with an intervention can potentially be confounded by the natural progression of HRQOL.

    Historically the lower Columbia and Willamette River Basins were ecologically rich in both the habitat types and the species diversity they supported. This was due in part to the pattern of floods and periodic inundation of bottomlands that occurred, which was an important factor in creating and maintaining a complex system of wetland, meadow, and riparian habitats. This landscape has been greatly altered in the past 150 years, primarily due to human development and agricultural activities including cattle grazing, logging and the building of hydroelectric facilities for hydropower, navigation, flood control and irrigation in the Columbia and Willamette River Basins. The Burlington Bottoms (BB) wetlands contains some of the last remaining bottomlands in the area, supporting a diverse array of native plant and wildlife species. Located approximately twelve miles northwest of Portland and situated between the Tualatin Mountains to the west and Multnomah Channel and Sauvie Island to the east, the current habitats are remnant of what was once common throughout the region. In order to preserve and enhance this important site, a five-year habitat management plan has been written that proposes a set of actions that will carry out the goals and objectives developed for the site, which includes protecting, maintaining and enhancing wildlife habitat for perpetuity.

    Purpose. To retrospectively evaluate the 10 year follow-up results in patients who had 'kissing' self-expanding stent aortic bifurcation reconstruction. Methods. Forty-three patients were treated with 'kissing' self-expanding stents for aortoiliac occlusive disease. Early follow-up with clinical and ankle brachial pressure indices (ABPI) was performed at 3, 6, 12, and 24 months and with intra-arterial digital subtraction angiography at 12-24 months; clinical and angiographic follow-up was performed for symptom recurrence up to 10 years after treatment. Retrospective record review was performed to assess mortality, clinical patency, angiographic patency, and secondary assisted patency of both stents and downstream peripheral vessels at 5 and 10 years follow-up. Results. The 2 year primary angiographic and secondary assisted stent patencies were 89% and 93%, respectively. At 10 years follow-up in 40 patients the mortality was 38% (due to myocardial infarction, stroke, chronic renal failure, malignancy, and liver failure). At 5 and 10 years follow-up the primary clinical stent patency was 82% and 68%, and the secondary assisted stent patency 93% and 86%, respectively. At 5 and 10 years, the distal vessel patency was 86% and 72%, and the secondary assisted distal vessel patency treated by surgical or endovascular techniques was 94% and 88%, respectively. At 10 years there was no limb loss. Conclusion. The long-term (10 year) results of aortic bifurcation arterial self-expanding stent placement in patients with arterial occlusive disease show a 10 year primary stent patency rate of 68% but a secondary assisted patency rate of 86%. In addition there is a high overall mortality due to other cardiovascular causes and the rate of distal disease progression and loss of patency is similar to the loss of stent patency rate

    The rock mechanics testing performed at the Earth Mechanics Institute of the Colorado School of Mines for Rockwell Hanford Operations under Subcontract SA-917 is summarized. Cores were supplied from drill hole DC-8 on the Hanford Site, characterized geologically, and tested for thermal and physical properties for designing long-term underground storage of radioactive waste materials. This report presents the approved test procedures, results, and data analysis for this test series. Results indicate significantly lower strengths for drill hole DC-8 than determined for drill hole DC-6 or for the drill holes reported on in our fiscal year 1978 (FY 78) tests. Trends, however, were found to be similar between drill holes DC-6 and DC-8, and it is hoped more definitive conclusions can be found following completion of the final series of tests

    Stiff skin syndrome is a rare sclerotic condition that presents during infancy or early childhood. It has an insidious chronic course and may lead to significant co-morbidity and reduced quality of life. Often, affected individuals experience impaired ambulation and immobilization related to joint involvement. Clinically, it may resemble other sclerotic diseases, so histopathological evaluation is necessary to establish a diagnosis. As it is a condition with limited treatment options, prompt diagnosis and early initiation of physical therapy is crucial to prevent joint restriction and maintain quality of life. We describe a case of a 7-year-old with stiff skin syndrome, and review the literature to discuss the clinical presentation, histological findings, and management of this condition.

    Mesenchymal stem cells have been used for cardiovascular regenerative therapy for decades. These cells have been established as one of the potential therapeutic agents, following several tests in animal models and clinical trials. In the process, various sources of mesenchymal stem cells have been identified which help in cardiac regeneration by either revitalizing the cardiac stem cells or revascularizing the arteries and veins of the heart. Although mesenchymal cell therapy has achieved considerable admiration, some challenges still remain that need to be overcome in order to establish it as a successful technique. This in-depth review is an attempt to summarize the major sources of mesenchymal stem cells involved in myocardial regeneration, the significant mechanisms involved in the process with a focus on studies (human and animal) conducted in the last 6 years and the challenges that remain to be addressed.

    Since January 1994, the Predatory Bird Research Group, University of California, Santa Cruz, has been conducting a field investigation of the ecology of golden eagles (Aquila chrysaetos) in the vicinity of the Altamont Pass Wind Resource Area (WRA). The 190 km{sup 2} facility lies just east of San Francisco Bay in California and contains about 6,500 wind turbines. Grassland and oak savanna habitats surrounding the WRA support a substantial resident population of golden eagles. Each year, the U.S. Fish and Wildlife Service receivers reports from the wind industry of about 30 golden eagle casualties occurring at the WRA, and it is probable that many more carcasses go unnoticed. Over 90 percent of the casualties are attributed to collisions with wind turbines. The main purpose of this study is to estimate the effect of turbine-related mortality on the golden eagle population of the area. Assessing the impact of the WRA kills on the population requires quantification of both survival and reproduction. To estimate survival rates of both territorial and non-territorial golden eagles, we tagged 179 individuals with radio-telemetry transmitters expected to function for about four years and equipped with mortality sensors. Population segments represented in the tagged sample include 79 juveniles, 45 subadults, 17n floaters (non-territorial adults), and 38 breeders. Effective sample sizes in the older segments increase as younger eagles mature or become territorial. Since the beginning of the study, we have conducted weekly roll-call surveys by airplane to locate the tagged eagles in relation to the WRA and to monitor their survival. The surveyed area extends from the Oakland Hills southeast through the Diablo Mountain Range to San Luis Reservoir about 75 km southeast of the WRA. The surveys show that breeding eagles rarely enter the WRA while the non-territorial eagles tend to move about freely throughout the study area and often visit the WRA.

    BACKGROUND Most studies on religion/spirituality predicting health outcomes have been limited to church attendance as a predictor and have focused on healthy people. However, confronting a major medical crisis may be a time when people turn to the sacred. OBJECTIVE The purpose of this study was to determine the extent to which changes in spirituality/religiousness occur after HIV diagnosis and whether changes predict disease progression. DESIGN/PARTICIPANTS This longitudinal study examined the relationship between changes in spirituality/religiousness from before with after the diagnosis of HIV, and disease progression (CD4 and viral load [VL] every 6 months) over 4 years in 100 people with HIV. Measures included change in religiousness/spirituality after diagnosis of HIV, religiousness/spirituality at various times in one’s life, church attendance, depression, hopelessness, optimism, coping (avoidant, proactive), social support, CD4/VL, and health behaviors. RESULTS Forty-five percent of the sample showed an increase in religiousness/spirituality after the diagnosis of HIV, 42% remained the same, and 13% decreased. People reporting an increase in spirituality/religiousness after the diagnosis had significantly greater preservation of CD4 cells over the 4-year period, as well as significantly better control of VL. Results were independent of (i.e., held even after controlling for) church attendance and initial disease status (CD4/VL), medication at every time point, age, gender, race, education, health behaviors (adherence, risky sex, alcohol, cocaine), depression, hopelessness, optimism, coping (avoidant, proactive), and social support. CONCLUSIONS There is an increase in spirituality/religiousness after HIV diagnosis, and this increase predicts slower disease progression; medical personnel should be aware of its potential importance.

    This progress report (H22 Report) documents progress made during JAEA 1st Midterm Plan (FY 2005 - 2009) to provide the scientific base for assessing geosphere stability for long-term isolation of the high-level radioactive waste. For the current 5-year R and D programme, three major goals have been defined as follows: 1) development and systematization of investigation techniques for selecting suitable sites in geosphere stability, 2) development, application and verification of prediction models for evaluating the changes of geological environment in thermal, hydraulic, mechanical and geochemical conditions for a long period of time, and 3) development of new dating techniques for providing information about geologic history and the timing of geologic events. For investigation techniques, an extracting technique of active faults with weak surface expressions by LiDAR, an integrated approach combining geophysical and geochemical methods for detecting crustal magma storage and an estimating method for uplift rates in an inland area using relative heights of fluvial terraces have been made. A numerical simulation code for predicting landform evolution in the next 100,000 years, and incorporating models of geophysical processes directly into probabilistic assessments for renewed volcanism using Bayesian inference (multiple inference model) have been prepared for prediction models. Improvement of AMS system for 14 C dating was conducted in order to precisely determine isotopic compositions. (U-Th)/He and K-Ar dating systems were also installed at Tono Geoscience Center (TGC) for determining the production age of fault gouge and precipitated within open fractures. In this paper, the current status of R and D activities with previous scientific and technological progress is summarized. (author)

A systematic review approach was used to document the ongoing AHSyS initiatives (active systems and those in pilot phase and recent methodological developments. Clinical data from practitioners and laboratory data remain the main data sources for AHSyS. However, although not currently integrated into prospectively running initiatives, production data, mortality data, abattoir data, and new media sources (such as Internet searches have been the objective of an increasing number of publications seeking to develop and validate new AHSyS indicators. Some limitations inherent to AHSyS such as reporting sustainability and the lack of classification standards continue to hinder the development of automated syndromic analysis and interpretation. In an era of ubiquitous electronic collection of animal health data, surveillance experts are increasingly interested in running multivariate systems (which concurrently monitor several data streams as they are inferentially more accurate than univariate systems. Thus, Bayesian methodologies, which are much more apt to discover the interplay among multiple syndromic data sources, are foreseen to play a big part in the future of AHSyS. It has become clear that early detection of outbreaks may not be the principal expected benefit of AHSyS. As more systems will enter an active prospective phase, following the intensive development stage of the last 5 years, the study envisions AHSyS, in particular for livestock, to significantly contribute to future international-, national-, and local-level animal health intelligence, going beyond the detection and

    In this short overview we have illustrated 30 years of progress in the field of ADHD neuropsychology through a selective presentation of studies published in the JCPP. Clearly this is not an exhaustive list of papers (we had to leave many excellent studies out) and obviously many studies published in other journals have had an equally significant impact on the field. Nevertheless, it is clear that the JCPP has contributed in important ways to providing the empirical and intellectual foundations of the next generation of ADHD neuropsychological models in terms of insight regarding context dependence, complexity and heterogeneity, and diagnostic specificity and sensitivity. Furthermore, articles have highlighted the importance of a developmental perspective on neuropsychological deficits in ADHD as well as the possibility that they could be targeted with new and novel treatments. Our hope is that we will continue to witness similar growth in understanding over the next 30 years, and that the JCPP will continue to be at the forefront of this progress. © 2014 Association for Child and Adolescent Mental Health.

    An association between degenerative changes in the lumbosacral region of the vertebral column and clinical signs of pain and pelvic limb dysfunction has long been recognized in dogs and has become known as degenerative lumbosacral stenosis syndrome. Over the past two decades, methods of imaging this condition have advanced greatly, but definitive criteria for a reliable diagnosis using physical examination, imaging and electrodiagnostics remain elusive. Available treatment options have changed little over more than 30 years but, more importantly, there is a lack of comparative studies and little progress has been made in providing evidence-based recommendations for the treatment of affected dogs. This review provides an overview of the changes in diagnosis, understanding and treatment of lumbosacral disease in dogs over the past 30 years. Approaches to address the unanswered questions regarding treatment choice are also proposed. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Fluvial sedimentary archives are important repositories for Lower and Middle Palaeolithic artefacts throughout the 'Old World', especially in Europe, where the beginning of their study coincided with the realisation that early humans were of great antiquity. Now that many river terrace sequences can be reliably dated and correlated with the globally valid marine isotope record, potentially useful patterns can be recognized in the distribution of the find-spots of the artefacts that constitute the large collections that were assembled during the years of manual gravel extraction. This paper reviews the advances during the past two decades in knowledge of hominin occupation based on artefact occurrences in fluvial contexts, in Europe, Asia and Africa. As such it is an update of a comparable review in 2007, at the end of IGCP Project no. 449, which had instigated the compilation of fluvial records from around the world during 2000-2004, under the auspices of the Fluvial Archives Group. An overarching finding is the confirmation of the well-established view that in Europe there is a demarcation between handaxe making in the west and flake-core industries in the east, although on a wider scale that pattern is undermined by the increased numbers of Lower Palaeolithic bifaces now recognized in East Asia. It is also apparent that, although it seems to have appeared at different places and at different times in the later Lower Palaeolithic, the arrival of Levallois technology as a global phenomenon was similarly timed across the area occupied by Middle Pleistocene hominins, at around 0.3 Ma.

    Congress passed the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) (Public Law 96-510), commonly known as Superfund, in 1980. The Superfund Amendments and Reauthorization Act (SARA) (Public Law 99-499), which amended CERCLA in 1986, added Section 120 regarding the cleanup of contaminated sites at Federal facilities. Under Section 120(e)(5) of CERCLA, each department, agency, or instrumentality of the Federal government responsible for compliance with Section 120 must submit an annual report to Congress concerning its progress in implementing the requirements of Section 120. The report must include information on the progress in reaching Interagency Agreements (IAGs), conducting Remedial Investigation and Feasibility Studies (RI/FSs), and performing remedial actions. Federal agencies that own or operate facilities on the National Priorities List (NPL) are required to begin an RI/FS for these facilities within 6 months after being placed on the NPL. Remediation of these facilities is addressed in an IAG between the Federal agency, the U.S. Environmental Protection Agency (EPA), and in some instances the state within which the facility is located. This report, prepared by the U.S. Department of Energy's (DOE's) Office of Environmental Management, is being submitted to Congress in accordance with Section 120(e)(5) of CERCLA. It is DOE's Eighth Annual Report to Congress and provides information on DOE's progress in implementing CERCLA Section 120 in Fiscal Year 1994 (FY 94), i.e., from October 1, 1993, to September 30, 1994.

    Food-borne cadmium was the principal source of exposure for persons living in the 12 cadmium-contaminated villages in Mae Sot District, Tak Province, northwestern Thailand. This report presents progress in cadmium-related health effects among persons with high cadmium exposure. The study included 436 persons who had urinary cadmium levels ≥5 μg/g creatinine and were screened for urinary cadmium, renal function, hypertension, diabetes and urinary stones in 2005 (baseline) and 2010 (5-year follow-up). Study renal biomarkers included urinary excretion of β 2 -microglobulin (β 2 -MG), total protein and calcium, serum creatinine and glomerular filtration rate (GFR). The geometric mean level of urinary cadmium statistically significantly reduced from 9.5±1.6 μg/g creatinine in 2005 to 8.8±1.6 μg/g creatinine in 2010. Compared to baseline, the follow-up examination revealed significant increases in urinary β 2 -MG (tubular effect), urinary total protein and serum creatinine, and a decrease in GFR (glomerular effects). Progressive renal dysfunctions were similarly observed in persons both with and without reduction in cadmium intake. Significant increases in prevalence of hypertension, diabetes and urinary stones were also detected at follow-up. These three disorders were found to markedly impair renal functions in the study persons. Our study indicates that in persons with prolonged excessive cadmium exposure, toxic health effects may progress even after exposure reduction. Renal damage from cadmium can be due to its direct nephrotoxic effect and also through the related disorders causing nephropathy.

    A 28-year-old Japanese male without a significant past medical history presented with new-onset generalized clonic seizure and headache. A brain MRI revealed multiple enhanced lesions on both cerebral hemispheres. Laboratory exams showed no evidence of systemic inflammation or auto-immune antibodies such as ANCAs. Despite four courses of high-dose methylprednisolone pulse therapy and five treatments with plasmapheresis, his symptoms worsened and the MRI lesions progressed rapidly. During these treatments, we performed a targeted brain biopsy, that revealed histological findings consistent with a predominant angiitis of parenchymal and subdural small vessels. He was provided with diagnosis of central nervous system vasculitis (CNSV). Subsequent cyclophosphamide pulse therapy enabled a progressive successful improvement of his symptoms. While diagnostic methods for CNSV remain controversial, histological findings are thought to be more useful in obtaining a more definitive diagnosis than findings in image studies, such as MRI and angiography. We suggest that a brain biopsy should be considered during the early period of cases with suspected CNSV and rapid clinical deterioration. We also detected human herpesvirus 7 (HHV-7) using PCR technology in brain biopsy specimens, however the relationship between CNSV and HHV-7 infection is unknow.

    The extent to which renal progression after acute kidney injury (AKI) arises from an initial step drop in kidney function (incomplete recovery), or from a long-term trajectory of subsequent decline, is unclear. This makes it challenging to plan or time post-discharge follow-up. This study of 14651 hospital survivors in 2003 (1966 with AKI, 12685 no AKI) separates incomplete recovery from subsequent renal decline by using the post-discharge estimated glomerular filtration rate (eGFR) rather than the pre-admission as a new reference point for determining subsequent renal outcomes. Outcomes were sustained 30% renal decline and de novo CKD stage 4, followed from 2003-2013. Death was a competing risk. Overall, death was more common than subsequent renal decline (37.5% vs 11.3%) and CKD stage 4 (4.5%). Overall, 25.7% of AKI patients had non-recovery. Subsequent renal decline was greater after AKI (vs no AKI) (14.8% vs 10.8%). Renal decline after AKI (vs no AKI) was greatest among those with higher post-discharge eGFRs with multivariable hazard ratios of 2.29 (1.88-2.78); 1.50 (1.13-2.00); 0.94 (0.68-1.32) and 0.95 (0.64-1.41) at eGFRs of 60 or more; 45-59; 30-44 and under 30, respectively. The excess risk after AKI persisted over ten years of study, irrespective of AKI severity, or post-episode proteinuria. Thus, even if post-discharge kidney function returns to normal, hospital admission with AKI is associated with increased renal progression that persists for up to ten years. Follow-up plans should avoid false reassurance when eGFR after AKI returns to normal. Copyright © 2017 International Society of Nephrology. Published by Elsevier Inc. All rights reserved.

    2003-09-01

    The relationships among walk steps, exercise habits and peak oxygen consumption (VO2peak), ventilatory threshold (VT) and leg extension power (LEP) were examined in 709 apparently healthy Japanese subjects (male 372, female 337) aged 30-69 years. Walk steps were evaluated using a pedometer. VO2peak and VT were assessed by a cycle ergometer test, while LEP was measured with an isokinetic leg extension system (Combi, Anaero Press 3500, Japan). Subjects who participated in exercise three times or more a week demonstrated significantly greater VO2peak and VT when compared with subjects without exercise habits. When a separate analysis was conducted on subjects who exercised fewer than three times per week, we found that the subgroup with the highest number of walk steps showed significantly greater VT in all male subjects and female subjects aged 30-49 years, but a significantly greater VO2peak only in females aged 30-49 years, when compared to the subgroup with the fewest walk steps. These results suggest that although some people exercise less than three times a week, if they are quite active in daily life, such activities might also confer benefits upon their fitness.

    Freedom Solo (FS) is a pericardial stentless heart valve showing excellent haemodynamic performance at mid-term. The aim of this study was to evaluate the long-term performance of such bioprostheses. Between December 2004 and November 2009, 109 patients (31 men; mean age 76 ± 6 years) underwent aortic valve replacement with FS. Preoperatively, the mean NYHA class was 2.5 ± 0.7, the mean EuroSCORE II, 2.8 ± 2.5. Mean prosthesis size was 22.7 ± 1.9 mm; concomitant procedures were performed in 65 patients. Structural valve deterioration (SVD) was diagnosed according to the Valve Academic Research Consortium-2 definition. Two patients (1.8%) died within 30 days. Follow-up (72 ± 36 months) was 100% completed. The 1-, 5- and 10-year actuarial survival rates were 89, 73 and 42%, respectively, with 8 valve-related deaths; the actuarial freedom from SVD was 99, 93 and 76%. During 61 ± 39 months of follow-up, echocardiographic findings worsened progressively: At discharge, 3-5 and 7-9 years, the mean gradient was 8 ± 4, 12 ± 11 and 19 ± 19 mmHg ( P  < 0.01); the indexed effective orifice area was 1.0 ± 0.2, 0.9 ± 0.2 and 0.8 ± 0.3 cm 2 /m 2 ( P  < 0.01). Of the 13 patients who developed SVD, it was due to aortic stenosis in 11. SVD was a predictor of cardiovascular mortality at univariate analysis (HR 2.87, 1.12-7.29); 2 explanted prostheses showed massive calcium deposits with mean calcium and phosphorus contents of 234 ± 16 and 116 ± 7 mg/g dry weight, respectively. The FS bioprosthesis shows excellent mid-term clinical and haemodynamic results and offers an alternative to other valves, particularly in the case of a small aortic annulus. Worsening of FS performance was observed at late follow-up because of progressive SVD with stenosis, questioning whether it should be used in patients with a long life expectancy. © The Author 2017.

    A life extension program has been developed for the US Department of Energy's Advanced Test Reactor. The program is an adaptation of life extension pilot programs at the Surry Unit 1 and Monticello generating stations and is being completed in three phases. In Phase 1, the critical plant components were identified. In Phase 2, existing lifetime analyses and support data for the critical components were reviewed. The results from the review give a preliminary indication that an overall plant lifetime in excess of forty years is feasible. In Phase 3, now in progress, detailed evaluations for component life extensions are being performed. 2 refs., 2 figs., 1 tab

  19. A 200 year sedimentary record of progressive eutrophication in lake Greifen (Switzerland): Implications for the origin of organic-carbon-rich sediments

    Science.gov (United States)

    Hollander, David J.; McKenzie, Judith A.; Lo Ten Haven, H.

    1992-09-01

    Over the past 200 years Lake Greifen, a small lake in northeastern Switzerland, has undergone dramatic changes in primary productivity and eutrophication due to increased nutrient supply from agricultural activity and industrialization. A 40 year historical record of the water-column chemistry indicates that productivity and eutrophication reached a maximum in 1974, after which stricter regulations on the input of nutrients resulted in a progressive decrease. Collected cores show the sedimentary expression of this anthropogenically induced eutrophication by a well-developed annual sedimentation and by enhanced values of total organic carbon, organic-carbon accumulation rates, and hydrogen indices (HI) of the kerogens. Analyses of the carbon isotopic composition of sedimentary carbonates and organic matter reveal that the fractionation between these two phases varies with the HI of kerogens. This observation is explicable in terms of changing productivity and preservation of the organic matter, and the CO2(aq) budget of the water body. We propose that if high primary productivity were primarily responsible for the preservation and accumulation of organic matter, then a negative correlation will occur between Δδ13Ccalcite-organic matter (Δδ13Ccal-om) and HI values. In an environment with relatively low to moderate productivity but with bottom-water anoxia, a positive correlation will exist between Δδ13Ccal-om and HI values. This study of Lake Greifen has implications for understanding paleoenvironmental controls on ancient organic-carbon-rich sediments.

    Prior to the introduction of viral inactivation of factor concentrates and screening of blood, 225 people with haemophilia became infected with hepatitis C (HCV) in Ireland. Our aim was to assess liver disease progression and mortality in this population after 30 years of infection. Demographic and clinical data were collected from medical records in five hepatology units and one infectious disease unit retrospectively in 2005, and on four subsequent occasions. The participation rate was 73% (165/225). Eighty three percent of patients, who had been tested for RNA (n = 106/128), developed chronic HCV infection. Thirty four percent were co-infected with HIV. All-cause mortality, after approximately 30 years of infection with chronic HCV, was 44% in HIV positive patients and 29% in HIV negative patients. Liver-related mortality was 12.5% and did not vary significantly by HIV status. Thirty seven percent of patients had developed advanced liver disease, including 20% with cirrhosis and 9% with hepatocellular carcinoma. In the pre-interferon-free direct acting antivirals era, 57% (n = 60/106) of patients were treated for HCV, 65% of whom achieved a sustained virological response. Successfully treated patients had few adverse liver outcomes. After 30 years of infection, 40% of the patients who had evidence of chronic HCV had developed advanced liver disease, such as cirrhosis and HCC, or had died from liver-related causes. This proportion is high relative to similar international cohorts despite good anti-HCV treatment uptake and responses. © 2017 John Wiley & Sons Ltd.

    Full Text Available All available rainfall statistics recorded for the Kruger National Park area since 1907, coupled with an analysis of all the historical climatological data on hand, appear to confirm the quasi-twenty-year rainfall oscillation in precipitation pattern for the summer rainfall area. This was first pointed out by Tyson & Dyer (1975. The dendrochronological data obtained by Hall (1976 from a study of growth rings of a very old yellowwood tree (Podocarpus falcatus in Natal, also appear to indicate a superimposed, long-term (80-100 years pattern of alternate below- average and above-average rainfall periods. The historical data relating to climate in the park, during the past century or two, seem to bear out such a pattern. If this can be confirmed, it will be an enormous aid not only in wildlife-management planning, but also to agriculturists, demographic planners and others. It would appear that the long, relatively dry rainfall period of 1860-1970, with its concomitant progressive desiccation of the @ area in question, has passed over into the next aboveverage rainfall era. This does not mean that there will be no further cataclysmic droughts during future rainfall trough periods. It is therefore wise to plan ahead to meet such contingencies. The present water distribution pattern in the park (natural plus artificial water is conspicuously still well below that which pertained, during dry seasons, at the turn of the century, when the Sabi and Shingwedzi game reserves were proclaimed. It is the declared policy of the National Parks Board of Trustees to simulate natural regulating mechanisms as closely as possible. In consequence the artificial water-for-game program is a long way from completion. The large numbers of game animals in the park (including dominant species such as elephant Loxodonta africana and buffalo Syncerus coffer can no longer migrate out of the area to escape natural catastrophes (such as the crippling droughts of 1911-1917, the

    Full Text Available Objective: to assess liver function changes in patients with spondyloarthritis (SpA taking NSAIDs regularly over a long period.Patients and methods. The data obtained during a 10-year PROGRESS prospective single-center cohort study of functional status, activity, and comorbidity (including gastrointestinal tract diseases in patients with SpA were analyzed. The data of 363 SpA patients receiving NSAIDs regularly over a long period and followed up for 10 years were also explored. The changes that had occurred over a decade in the liver enzyme levels, the number of discontinued NSAID treatments because of a persistent increase in liver enzyme levels, and the number of prescriptions of hepatoprotective agents were analyzed.Results. For 10 years, 18 patients with SpA discontinued their NSAID intake due to elevated liver enzyme levels (≥3 times greater than the reference value; during that time, the same increase in enzyme levels was observed in 2 healthy individuals (χ2 =1.39; p=0.2. In the patients with SpA as compared to the healthy individuals, the relative risk of abnormal liver function was 1.19 (95% CI, 1.009–1.405; odds ratio was 2.9 (95% CI, 0.65–12.95. There was no increased risk for discontinuation of some NSAIDs, including nimesulide (χ2 =0.03, p=0.85, the frequency of using hepatoprotective drugs was proved to be highest for diclofenac sodium, ibuprofen, nimesulide, and ketoprofen.Conclusion. The regular long-term (as long as 10 years use of NSAIDs to treat SpA is associated with treatment discontinuation because of elevated enzyme levels in every 10 patients. The maximum rate of discontinuation of NSAIDs due to a persistent increase in liver enzyme levels is observed 6–8 years after their regular use, so long-term NSAID therapy requires continuous monitoring of hepatic safety. The longterm intake of nimesulide, as compared with other NSAIDs, is shown to be unassociated with the higher rate of its discontinuation because of

    We report a 65-year-old man with progressive loss of vision and consciousness disturbance. The patient was well until his age of 63 when he was found to have a gastric cancer. He was treated by the tumor resection and chemotherapy; he was apparently well, but hepatic metastases were found in the next year (1996). In June, 1996, he noted an onset of blurred vision more on the left. He was admitted to the ophthalmology service of our hospital on July 14, 1996. His vision was 0.8 on the right and 0.15 on the left. He was treated with oral prednisolone with slight improvement. He was also found to have IgM kappa-type monoclonal gammopathy; Bence-Jones protein was positive and a bone marrow aspiration revealed that approximately 10% of bone marrow cells were atypical plasma cells. His vision had progressively got worse and he became blind by the end of October 1996. A chest X-ray and cranial CT scan revealed multiple abnormal nodular densities. In the middle of November 1996, he became confused, disoriented and agitated. His mental symptoms had progressively became worse, and a neurologic consultation was asked on December 10, 1996. Neurologic examination revealed that he was somnolent with decreased attention to his surroundings. He showed marked disorientation and memory loss. Higher cerebral functions appeared intact. He was able to recognize only light and dark. Pupils were moderately dilated with very sluggish light reflex remained. Vertical gaze was moderately restricted and horizontal nystagmus was noted upon left and right lateral gaze. The remaining of the neurologic examination were unremarkable. General physical examination revealed hepatosplenomegaly; the liver was palpable by 3 cm below the right costal margin. Laboratory examination revealed anemia (Hb10.1 g/dl) and thrombocytopenia (43,000/microliter). A cranial CT scan and MRI revealed a mass lesion in involving the chiasmatic and bilateral hypothalamic areas. The tumor showed intense homogeneous

  6. Progress and Impact of 13 Years of the Global Programme to Eliminate Lymphatic Filariasis on Reducing the Burden of Filarial Disease

    Ramaiah, K. D.; Ottesen, Eric A.

    2014-01-01

    Background A Global Programme to Eliminate Lymphatic Filariasis was launched in 2000, with mass drug administration (MDA) as the core strategy of the programme. After completing 13 years of operations through 2012 and with MDA in place in 55 of 73 endemic countries, the impact of the MDA programme on microfilaraemia, hydrocele and lymphedema is in need of being assessed. Methodology/Principal findings During 2000–2012, the MDA programme made remarkable achievements – a total of 6.37 billion treatments were offered and an estimated 4.45 billion treatments were consumed by the population living in endemic areas. Using a model based on empirical observations of the effects of treatment on clinical manifestations, it is estimated that 96.71 million LF cases, including 79.20 million microfilaria carriers, 18.73 million hydrocele cases and a minimum of 5.49 million lymphedema cases have been prevented or cured during this period. Consequently, the global prevalence of LF is calculated to have fallen by 59%, from 3.55% to 1.47%. The fall was highest for microfilaraemia prevalence (68%), followed by 49% in hydrocele prevalence and 25% in lymphedema prevalence. It is estimated that, currently, i.e. after 13 years of the MDA programme, there are still an estimated 67.88 million LF cases that include 36.45 million microfilaria carriers, 19.43 million hydrocele cases and 16.68 million lymphedema cases. Conclusions/Significance The MDA programme has resulted in significant reduction of the LF burden. Extension of MDA to all at-risk countries and to all regions within those countries where MDA has not yet reached 100% geographic coverage is imperative to further reduce the number of microfilaraemia and chronic disease cases and to reach the global target of interrupting transmission of LF by 2020.

    This document contains the progress report on the first half year of the CATO-2 WP5.2 PhD project 'Framing effects in communication about CCS'. In the first few months a literature study has been conducted, both on (factors that influence) public perceptions and acceptance of CCS, and on framing. In the last two month, a first study was designed. This study consists of an experiment designed to examine how framing a company's involvement in CCS in terms of economic benefits and/or CSR of the organization affects the corporate image, trust, and perceived 'greenwashing' (deceit). Furthermore, this experiment serves to test the quality of newly developed questionnaires to measure these variables. In addition, this document contains a detailed description of the research planned for WP5.2 written by senior (CATO-2) researchers from January 2010 on. The objective of the research planned for WP5.2 is to examine whether framing of communications by an organization can improve the perceived credibility and trustworthiness of the organization and the information provided. This issue will be examined by a combination of experimental studies and a survey-type study.

  10. Velocity distribution of electrons in time-varying low-temperature plasmas: progress in theoretical procedures over the past 70 years

    2018-03-01

    A time-varying low-temperature plasma sustained by electrical powers with various kinds of fRequencies has played a key role in the historical development of new technologies, such as gas lasers, ozonizers, micro display panels, dry processing of materials, medical care, and so on, since World War II. Electrons in a time-modulated low-temperature plasma have a proper velocity spectrum, i.e. velocity distribution dependent on the microscopic quantum characteristics of the feed gas molecule and on the external field strength and the frequency. In order to solve and evaluate the time-varying velocity distribution, we have mostly two types of theoretical methods based on the classical and linear Boltzmann equations, namely, the expansion method using the orthogonal function and the procedure of non-expansional temporal evolution. Both methods have been developed discontinuously and progressively in synchronization with those technological developments. In this review, we will explore the historical development of the theoretical procedure to evaluate the electron velocity distribution in a time-varying low-temperature plasma over the past 70 years.

    This project was established with a new interagency agreement between the Department of Energy and the Department of Transportation to provide collaborative research, development, and benchmarking of advanced three-dimensional computational mechanics analysis methods to the aerodynamics and hydraulics laboratories at the Turner-Fairbank Highway Research Center for a period of five years, beginning in October 2010. The analysis methods employ well-benchmarked and supported commercial computational mechanics software. Computational mechanics encompasses the areas of Computational Fluid Dynamics (CFD), Computational Wind Engineering (CWE), Computational Structural Mechanics (CSM), and Computational Multiphysics Mechanics (CMM) applied in Fluid-Structure Interaction (FSI) problems. The major areas of focus of the project are wind and water loads on bridges - superstructure, deck, cables, and substructure (including soil), primarily during storms and flood events - and the risks that these loads pose to structural failure. For flood events at bridges, another major focus of the work is assessment of the risk to bridges caused by scour of stream and riverbed material away from the foundations of a bridge. Other areas of current research include modeling of flow through culverts to assess them for fish passage, modeling of the salt spray transport into bridge girders to address suitability of using weathering steel in bridges, vehicle stability under high wind loading, and the use of electromagnetic shock absorbers to improve vehicle stability under high wind conditions. This quarterly report documents technical progress on the project tasks for the period of January through March 2011.

    At Lake Chapala (103° 02'W, 20° 15'N) a linear sedimentation rate of 2 mm a-1 for the last 12,000 years was deduced from ten 14C dates. Due to the presence of very old hydrothermal bitumen (14C date: >40,000 years BP) a reservoir effect of c. 2000 years must be taken into account. Pollen results indicate a generally increase in dry forest taxa with an interruption during the middle Holocene. Diatom results allow a zonation into 6 paleoenvironmental phases. Zone 1: From 27 to 26m depth (c. 12,000 yBP), Stephanodiscus niagaraeis the dominant taxa in coincidence with high TOC percents; a transgression into moister conditions is indicated. Zone 2: From 26 to 17m (10,310-8720 cal BP) it is characterized by Aulacoseira granulata indicating an increase in ionic conditions and turbidity in lake as result of a decrease in lacustrine levels. Zone 3: From 17 to 13m (8720-5950 cal BP) it is dominated by C. aff. kuetzingiana and the presence of temperate pollen taxa at 12 m (ca. 5000 YBP) suggest an increase in humid conditions in this interval. Zone 4: From 13 to 8.5m (5950-2840 cal BP) encompass the middle Holocene. Stephanodiscus medius alternating with Surirella ovalis characterize this period and indicate very fluctuant conditions in coincidence with at a decrease of low TOC percents. Zone 5: From 8.5 to 4m (2840-1580 cal BP), mark the establishment of modern conditions until present, with a peak in S. ovalis in coincidence with the high A. granulata, indicating low lake, saline, turbid and more extreme conditions at the base and top of this interval. Zone 6: From 4 to 0m (1580 cal BP to Present) S. medius (over 50%), C. aff. dubius (20 to 40%), perifitic diatoms in low percents (<5%), and A. granulata and S.ovallis in spite of few percents, are observed in concordance with a return of saline conditions of the lake, indicate a regressive phase.

    Full Text Available Transformation of the urothelium to the intestinal type of epithelium is rare in the pelvis with very few cases reported in the literature. The present study reports extensive intestinal metaplasia of the pelvi-calyceal system without residual urothelium in a 35-years-old woman with a 2 years history of renal calculi. Right - sided Nephrectomy was undertaken. Immunohistochemistry of the metaplastic epithelium revealed positive expression of CK20, low Ki-67 index and negative expression of p53. In this patient long standing metaplastic changes did not progress to adenocarcinoma which indicates that extensive intestinal metaplasia is not always associated with malignancy.

    In USA where the development of nuclear power was started early, the life of nuclear power plants expires successively around the turn of century, and the serious hindrance to electric power supply is feared. Therefore, the research for extending 40 year approved period of operation is in progress. By the extension of life of nuclear power plants, huge cost reduction is estimated as compared with the construction of new plants. However, due to the rise of the cost for the life extension, there were the cases of forced decommissioning. In this book, the present state of the life extension of nuclear power stations, the economical assessment and analysis of the life extension by DOE, the economical assessment by MIDAS method of Electric Power Research Institute, the economical assessment by cost-benefit method of Northern States Power Co., the assessment of the long term operation possibility of nuclear power stations, the economical assessment system for the life extension in Japan, the present state of the decommissioning of nuclear power stations and that in USA, Canada and Europe, the assessment of the decommissioning cost by OECD/NEA, and the decommissioning cost for thermal power stations are described.

    2013-06-01

    Why, more than 20 years ago, did there emerge the need for an International System on Occupational Exposure (ISOE)? How was it created? What were the problems and their possible solutions? Who were the main stakeholders? These are a few of the questions that the ISOE NEA Secretariat and Bureau asked Christian Lefaure, ex CEPN Deputy Director, to address in preparing a report on the history of ISOE and its progress. He had been directly involved in the brainstorming that preceded ISOE establishment, and he became the first head of the ISOE European Technical Centre, in charge of the world database development and management from 1991 to 2007. For writing this report, he made use of his own souvenirs and documentation as well as of those of tens of ISOE participants, both from major international and regional organisations (OECD/NEA, IAEA, EC and BNL), nuclear power plant utilities and national regulatory authorities. He voluntarily focused not only on the technical aspects but also on the human components of that story. This was done through personal interviews with many individuals who have played an important role at one moment of ISOE life, the analysis of answers to a questionnaire, and reviews of the minutes of many ISOE meetings that were held before and after the official establishment of the ISOE, along its lifespan to date. The most important inputs were the accounts from many individuals having very actively participated in the ISOE life at one step or another. The contacts were not always easy to make 15 or 20 years later. But in general, the questions were welcomed and the answers to the interviews and to a short questionnaire have fed this report. More than 50 individuals have answered these requests one way or another. Some have followed ISOE birth and premises; some have not seen the first steps of ISOE but have participated later on or are still participating. Some have been able to provide pictures, drawings or relevant publications. All their

    The long-term effects of tumor necrosis factor (TNF)-blocking therapies on weight-bearing joints in patients with rheumatoid arthritis (RA) have not been fully characterized. The purpose of this study was to assess the radiographic changes of weight-bearing joints in patients with RA during 3-year of TNF-blocking therapies and to identify factors related to the progression of joint damage. Changes in clinical variables and radiological findings in 243 weight-bearing joints (63 hips, 54 knees, 71 ankles, and 55 subtalar joints) in 38 consecutive patients were investigated during three years of treatment with TNF-blocking agents. Multivariate logistic regression analysis was used to identify risk factors for the progression of weight-bearing joint damage. Seventeen (14.5%) of proximal weight-bearing joints (hips and knees) showed apparent radiographic progression during three years of treatment, whereas none of the proximal weight-bearing joints showed radiographic evidence of improvement or repair. In contrast, distal weight-bearing joints (ankle and subtalar joints) displayed radiographic progression and improvement in 20 (15.9%) and 8 (6.3%) joints, respectively. Multivariate logistic analysis for proximal weight-bearing joints identified the baseline Larsen grade (p bearing joints identified disease activity at one year after treatment (p bearing joints. Disease activity after treatment was an independent factor for progression of damage in proximal and distal weight-bearing joints. Early treatment with TNF-blocking agents and tight control of disease activity are necessary to prevent the progression of damage of the weight-bearing joints.

    circumcision (the Sunna form) is a religious requirement 16.5 (2.43-112.6) and the Sunna form is not harmful 25.1(2.35-281.1), are the two factors significantly associated with the continuation of female circumcision. Moreover, females were less likely to support the continuation of FC compared to their male counterparts (aOR 0.07; CI: 0.05-0.88). The study shows that the support towards the persistence of the practice is profoundly high in Somalia. People are aware of the health and human rights effect of female circumcision, and yet they support the continuation of the practice. Therefore, over 30 years of campaigns with limited progress demand an alternative approach towards the eradication of female circumcision in Somalia.

    Full Text Available Chronic renal failure (CRF is almost always associated with high arterial blood pressure. Adequate control of hypertension slows down the progression of the disease, Inhibitors of angiotenzin-converting enzyme (ACE inhibitors have proved to be very efficacious in decreasing high blood pressure. The aim of this study was to assess the influence of ACE inhibitor enalapril on the progression of CRF in patients with diabetic nephropathy and nephropathies of other origin. During 1998 and 1999 thirty patients (20 males and 10 females, aged 525+1.3 have been followed-up at the Department of Nephrology, Clinical Centre of Serbia. On regular monthly controls serum creatinine, urea, calcium and protein levels, creatinine clearance, and blood pressure, were measured. All patients were suggested a low protein diet. Progression of the disease was expressed by the slope of the regression line showing reciprocal serum creatinine values. Proteinaemia was significantly higher in diabetic patients after 12 months (p<0.35 but in the next 12 months the difference between groups disappeared. The same patients had significantly lower serum urea (p<0.05 after 24 months and creatinine values (p<0.05 dur ing the whole study. Other variables changed in the same manner and with similar progression in both groups. The direction of slope lines suggested recovery of kidney function in both examined groups. However, a smaller slope in patients with diabetic nephropathy together with other results showed that enalapril had better influence on slowing down the progression of CRF in this group of patients.

    The development and progress of antidiabetic drugs (e.g., insulin preparations and hypoglycemic drugs) are retrospectively investigated in Japan. Their influences on the treatment of diabetes mellitus (DM) and its epidemiological aspects are also discussed. 1) Insulin preparations: Insulin was introduced for DM therapy in 1925, two or three years after its discovery in Canada. The preparations were raw extracts of bovine or porcine pancreas. These did not prevail widely in Japan because of the low incidence of DM before World Wan II. After the war, a shortage of mammalian materials compelled the use of fish pancreatic tissues such as bonito and/or tuna for insulin production. Insulin infection, so-called regular insulin, was first promoted in the 6th "Pharmacopoeia Japonica" (JP6) in 1951 and has been maintained to the present edition (JP14, 2001). Although depot-type insulin preparations were developed in the USA and Europe during the war, the introduction of those preparations to Japan was delayed until 1951, when Protamine zinc insulin appeared. Globin zinc insulin and Isophane insulin were introduced for clinical use in 1952 and 1955, respectively. These were also adopted for JP7 (1961). Biphasic-type insulin, which has a rapid onset and long duration of activity, appeared in 1965. Purified preparations from bovine or porcine sources have been available since 1980, which might be a strong reason for the decrease in insulin allergy. Insulin from animal origin has been supplied for almost 60 years since its discovery. Amino acid sequences of insulins from various species of animals were determined by the pioneering studies of Sanger and his associates. Human insulin, which differs from porcine insulin by only one amino acid, was produced by Novo researchers in 1982 using a semi-synthetic method. Then the Lilly group soon succeeded in obtaining human insulin by recombinant DNA technology in the same year. Both products were introduced to Japan in 1985, and the

  19. Progress In Optical Memory Technology

    1987-01-01

    More than 20 years have passed since the concept of optical memory was first proposed in 1966. Since then considerable progress has been made in this area together with the creation of completely new markets of optical memory in consumer and computer application areas. The first generation of optical memory was mainly developed with holographic recording technology in late 1960s and early 1970s. Considerable number of developments have been done in both analog and digital memory applications. Unfortunately, these technologies did not meet a chance to be a commercial product. The second generation of optical memory started at the beginning of 1970s with bit by bit recording technology. Read-only type optical memories such as video disks and compact audio disks have extensively investigated. Since laser diodes were first applied to optical video disk read out in 1976, there have been extensive developments of laser diode pick-ups for optical disk memory systems. The third generation of optical memory started in 1978 with bit by bit read/write technology using laser diodes. Developments of recording materials including both write-once and erasable have been actively pursued at several research institutes. These technologies are mainly focused on the optical memory systems for computer application. Such practical applications of optical memory technology has resulted in the creation of such new products as compact audio disks and computer file memories.

    Familial short stature (FSS) and constitutional delay of growth (CDG) are the most frequent norm variants in children presenting with short stature. Knowing the growth patterns of these entities in the first years of life might be helpful to distinguish them from growth hormone deficiency (GHD) or other chronic diseases. We studied the height in the first 5 years of life in 26 children with FSS, in 38 children with CDG and in 14 children with idiopathic GHD. Height standard deviation scores (SDS) did not change between birth and 6 months of life, while height SDS decreased significantly afterwards in GHD, FSS, and CDG. The loss of height SDS was higher in the first 2 years of life than between 2 and 5 years of life in children with CDG (-0.92 vs. -0.11; p = 0.003) or FSS (-0.79 vs. -0.01; p = 0.002). In idiopathic GHD, the loss of height SDS did not differ between the first 2 years of life and the next 3 years (-0.78 vs. -0.77; p = 0.821). Children with FSS and CDG showed a decline in height SDS mainly in the first 2 years of life, whereas the height SDS of children with idiopathic GHD decreased almost continuously over the first 5 years of life. © 2016 S.

  10. Evidence of 11-year solar cycles in tree rings from 1010 to 1110 AD – Progress on high precision AMS measurements

    International Nuclear Information System (INIS)

    Güttler, D.; Wacker, L.; Kromer, B.; Friedrich, M.; Synal, H.-A.

    2013-01-01

    Oak tree rings from Southern Germany covering the AD 1010–1110 years have been analyzed for radiocarbon with accelerator mass spectrometry (AMS) at the laboratory at ETH Zurich. High-precision measurements with a precision down to 12 years radiocarbon age and a time resolution of 2 years aimed to identify modulations of the 14 C concentration in tree ring samples caused by the 11 years solar cycles, a feature that so far is not visible in the IntCal calibration curve. Our results are in good agreement with the current calibration curve IntCal09. However, we observed an offset in radiocarbon age of 25–40 years towards older values. An evaluation of our sample preparation, that included variations of e.g.: chemicals, test glasses and processing steps did not explain this offset. The numerous measurements using the AMS-MICADAS system validated its suitability for high precision measurements with high repeatability.

    2018-01-01

    Academic conferences offer numerous submission tracks to support the inclusion of a variety of researchers and topics. Work in progress papers are one such submission type where authors present preliminary results in a poster session. They have recently gained popularity in the area of Human Computer Interaction (HCI) as a relatively easier pathway to attending the conference due to their higher acceptance rate as compared to the main tracks. However, it is not clear if these work in progress papers are further extended or transitioned into more complete and thorough full papers or are simply one-off pieces of research. In order to answer this we explore self-citation patterns of four work in progress editions in two popular HCI conferences (CHI2010, CHI2011, HRI2010 and HRI2011). Our results show that almost 50% of the work in progress papers do not have any self-citations and approximately only half of the self-citations can be considered as true extensions of the original work in progress paper. Specific conferences dominate as the preferred venue where extensions of these work in progress papers are published. Furthermore, the rate of self-citations peaks in the immediate year after publication and gradually tails off. By tracing author publication records, we also delve into possible reasons of work in progress papers not being cited in follow up publications. In conclusion, we speculate on the main trends observed and what they may mean looking ahead for the work in progress track of premier HCI conferences.

    We describe a case of a 67-year-old man with systemic lupus erythematosus who presented with progressive left hemiplegia. Although the cerebral spinal fluid (CSF) polymerase chain reaction (PCR) for the JC virus was negative, a brain biopsy confirmed the diagnosis of progressive multifocal leukoencephalopathy (PML). The tapering of prednisone and the use of cidofovir could not arrest the disease progression. Administration of mefloquine stopped the extension of the lesion, and resulted in obvious clinical improvement. The CSF nested PCR for the JC virus also became negative. This widely used drug should be tried for the treatment of non-HIV PML.

    Giant cell tumor of bone (GCT) is a rare primary bone tumor, which can metastasize and undergo malignant transformation. The standard treatment of GCT is surgery. In patients with unresectable or metastatic disease, additional therapeutic options are available. These include blocking of the receptor activator of NF-kappa B ligand (RANKL) signaling pathway, which plays a role in the pathogenesis of GCT of bone, via the anti-RANKL monoclonal antibody denosumab. Herein we report on a female teenager who presented in a very poor clinical condition (cachexia, diplopia, strabismus, dysphonia with palsy of cranial nerves V, VI, VIII, IX, X, XI and XII) due to progressive disease, after incomplete resection and adjuvant radiotherapy, of a GCT which affected the cervical spine (C1 and C2) as well as the skull base; and who had an impressive clinical response to denosumab therapy. To the best of our knowledge, this is the youngest patient ever reported with a skull base tumor treated with denosumab. In situations when surgery can be postponed and local aggressiveness of the tumor does not urge for acute surgical intervention, upfront use of denosumab in order to reduce the tumor size might be considered. Principally, the goal of denosumab therapy is to reduce tumor size as much as possible, with the ultimate goal to make local surgery (or as in our case re-surgery) amenable. However, improvement in quality of life, as demonstrated in our patient, is also an important aspect of such targeted therapies.

    Full Text Available Abstract Background Many diabetic patients fear visual loss as the worst consequence of diabetes. In most studies the main eye pathology is assigned as the cause of visual impairment. This study analysed a broad range of possible ocular and non-ocular predictors of visual impairment prospectively in patients newly diagnosed with clinical type 2 diabetes. Methods Data were from a population-based cohort of 1,241 persons newly diagnosed with clinical, often symptomatic type 2 diabetes aged ≥ 40 years. After 6 years, 807 patients were followed up. Standard eye examinations were done by practising ophthalmologists. Results At diabetes diagnosis median age was 65.5 years. Over 6 years, the prevalence of blindness (visual acuity of best seeing eye ≤ 0.1 rose from 0.9% (11/1,241 to 2.4% (19/807 and the prevalence of moderate visual impairment (> 0.1; Conclusions In a comprehensive assessment of predictors of visual impairment, even in a health care system allowing self-referral to free eye examinations, treatable eye pathologies such as DR and cataract emerge together with age as the most notable predictors of continued visual loss after diabetes diagnosis. Our results underline the importance of eliminating barriers to efficient eye care by increasing patients' and primary care practitioners' awareness of the necessity of regular eye examinations and timely surgical treatment.

    Full Text Available Background: Whether Vitamin D supplementation in prediabetes subjects prevents the development of diabetes is a matter of debate, and the results are inconsistent. This open-label, randomized study in subjects with prediabetes evaluated the effect of 12 months of Vitamin D supplementation on glycemic parameters and progression of prediabetes to diabetes in an ethnically homogeneous Kashmiri population. Materials and Methods: A total of 147 subjects were diagnosed as prediabetes out of which 137 subjects were randomized to receive in addition to standard lifestyle measures, either Vitamin D 60,000 IU weekly for 4 weeks and then 60,000 IU monthly (n = 69 or no Vitamin D (n = 68. Fasting plasma glucose (FPG, 2-h plasma glucose and A1C levels were estimated at 0, 6 and 12 months. Changes in FPG, 2-h plasma glucose, A1C level and the proportion of subjects developing diabetes were assessed among 129 subjects. Results: At 12 months, A1C levels were significantly lesser (5.7% ± 0.4% in the Vitamin D supplemented group when compared with non-Vitamin D supplemented (6.0% ± 0.3%. Similarly, FPG (97 ± 7 and 2-h plasma glucose (132 ± 16 were significantly less in Vitamin D supplemented group as compared with non-Vitamin D supplemented group (FPG = 116 ± 6 and 2-h plasma glucose = 157 ± 25 at 12 months. Nine out of 65 in non-Vitamin D supplemented and seven out of 64 in the Vitamin D supplemented group developed diabetes. Conclusions: Vitamin D supplementation in prediabetes subjects significantly lowered FPG, 2-h plasma glucose and A1C levels.

    International audience; In proof theory one distinguishes sequent proofs with cut and cut-free sequent proofs, while for proof complexity one distinguishes Frege-systems and extended Frege-systems. In this paper we show how deep inference can provide a uniform treatment for both classifications, such that we can define cut-free systems with extension, which is neither possible with Frege-systems, nor with the sequent calculus. We show that the propositional pigeon-hole principle admits polyno...

  9. Dimension and extensions

    CERN Document Server

    Aarts, JM

    1993-01-01

    Two types of seemingly unrelated extension problems are discussed in this book. Their common focus is a long-standing problem of Johannes de Groot, the main conjecture of which was recently resolved. As is true of many important conjectures, a wide range of mathematical investigations had developed, which have been grouped into the two extension problems. The first concerns the extending of spaces, the second concerns extending the theory of dimension by replacing the empty space with other spaces. The problem of de Groot concerned compactifications of spaces by means of an adjunction of a set of minimal dimension. This minimal dimension was called the compactness deficiency of a space. Early success in 1942 lead de Groot to invent a generalization of the dimension function, called the compactness degree of a space, with the hope that this function would internally characterize the compactness deficiency which is a topological invariant of a space that is externally defined by means of compact extensions of a...

  10. How Feasible is Adequate Yearly Progress (AYP? Simulations of School AYP "Uniform Averaging" and "Safe Harbor" under the No Child Left Behind Act

    Directory of Open Access Journals (Sweden)

    Jaekyung Lee

    2004-04-01

    Full Text Available The No Child Left Behind Act of 2001 (NCLB requires that schools make “adequate yearly progress” (AYP towards the goal of having 100 percent of their students become proficient by year 2013-14. Through simulation analyses of Maine and Kentucky school performance data collected during the 1990s, this study investigates how feasible schools would have met the AYP targets if the mandate had been applied in the past with “uniform averaging (rolling averages” and “safe harbor” options that have potential to help reduce the number of schools needing improvement or corrective action. Contrary to some expectations, the applications of both options would do little to reduce the risk of massive school failure due to unreasonably high AYP targets for all student groups. Implications of the results for the NCLB school accountability system and possible ways to make the current AYP more feasible and fair are discussed.

    Early nutrition and growth have been found to be important early exposures for later development. Studies of crude growth in terms of weight and length/height, however, cannot elucidate how body composition (BC) might mediate associations between nutrition and later development. In this study, we aimed to examine the relation between fat mass (FM) or fat-free mass (FFM) tissues at birth and their accretion during early infancy, and later developmental progression. In a birth cohort from Ethiopia, 455 children who have BC measurement at birth and 416 who have standardised rate of BC growth during infancy were followed up for outcome variable, and were included in the statistical analysis. The study sample was restricted to mothers living in Jimma town who gave birth to a term baby with a birth weight ≥1500 g and no evident congenital anomalies. The relationship between the exposure and outcome variables was examined using linear-mixed regression model. The finding revealed that FFM at birth was positively associated with global developmental progression from 1 to 5 years (β=1·75; 95 % CI 0·11, 3·39) and from 4 to 5 years (β=1·34; 95 % CI 0·23, 2·44) in the adjusted model. Furthermore, the rate of postnatal FFM tissue accretion was positively associated with development at 1 year of age (β=0·50; 95 % CI 0·01, 0·99). Neither fetal nor postnatal FM showed a significant association. In conclusion, fetal, rather than postnatal, FFM tissue accretion was associated with developmental progression. Intervention studies are needed to assess whether nutrition interventions increasing FFM also increase cognitive development.

To perform a biomechanic analysis of the ΓR and the weighted mean moment arm (WMMA in order to calculate the resultant muscle force (FM R of the hip extensors and flexors. To present a mechanical criteria for progression of HE exercise on the Pilates Cadillac. METHODS: Fourteen participants performed HE exercises on the Cadillac in four randomly assigned situations - using two springs (blue and red, which were attached in two positions (high and low. Angular positions were measured using an electrogoniometer. In order to calculate ΓR, the muscle torque (ΓM and FM R, free-body diagrams and movement equations were used. The WMMA of the hip extensors and flexors were estimated from the literature. RESULTS: The ΓR and FM R presented a similar behavior during all situations; however, the maximum ΓR values did not occur at the same joint position as the FM R maximum values. The WMMA of the hip flexors presented an increased- decreased behavior with greatest values around 55º of flexion, while the hip extensors presented a similar behavior with greatest values around 25º of flexion. CONCLUSION: Biomechanic analysis of HE exercises and the evaluation of mechanical features in relation to the hip joint may be used as an objective criteria for the prescription and progression of HE exercise in Pilates.

    1976-01-01

    In studies conducted during the first three-year segment of this contract, it was observed that in the process of viral leukemogenesis the affected animals became more radioresistant than normal. Initial studies into the reason for the enhanced radioresistance implicated an increase in the number of pluripotent stem cells as one possible cause. During the current period, studies were carried out to further define the effect of the virus on stem cells and their kinetics using exposure to tritiated thymidine ( 3 HTdR) in vivo and in vitro. In addition, separate studies were initiated in an attempt to determine if the immune system played a part in the radioresistance, as well as what the effects might be of immune manipulations on the disease during the oncogenic period. Finally, studies were also undertaken to assess the sensitivity of the virus itself to radiation in vitro and in vivo to radiation and treatment with cells transplanted from viral resistant mice

    We are completing a 30-year study of the biological effects of {sup 90}Sr and {sup 226}Ra in the beagle in order to predict the possible long-term hazards to people from chronic exposure to low levels of irradiation. Animals received either radionuclide by several means of administration: (a) continual ingestion of {sup 90}Sr, (b) a single intravenous injection of {sup 90}Sr, or (c) a series of eight intravenous injections of {sup 226}Ra. Although administration of {sup 90}Sr and {sup 226}Ra ended at 540 days of age, the animals continued to receive chronic, low-level radiation doses from these bone-seeking radionuclides throughout life. This project is the largest single cohort study in beagles of internally deposited radionuclides. It is unique in use of the ingestion route for {sup 90}Sr and in exposure that began before birth and continued throughout development to adulthood with uniform labeling of the skeletons with {sup 90}Sr. The last of the dogs died in 1986 at age 18.5 years, but we are continuing to investigate the significance of these long-term exposures given at low dose rates with regard to cancer production, physiologic well-being, and shortening of life through the detailed records that were kept and by study of preserved materials. All the data have been successfully accumulated and entered into a main-frame computer data base management system. Current work is exclusively directed at preparing research papers summarizing the results and the associated biostatistical and survival analyses. 15 refs., 1 fig., 4 tabs.

    The effectiveness of tafamidis for the treatment of transthyretin familial amyloid polyneuropathy (TTR-FAP) was evaluated using data from the Transthyretin Amyloidosis Outcomes Survey (THAOS) registry. Subjects receiving tafamidis (n = 252) were compared with untreated subjects in a non-randomized, matched cohort analysis. Subjects were matched with up to four untreated controls by genetic mutation, region of birth, and mean treatment propensity score. The matched, treated sample consisted predominantly of subjects with the Val30Met genotype (92.5%), from Portugal, and with a mean age of 40.4 years. Over the course of the 2-year follow-up period, subjects treated with tafamidis showed significantly less deterioration on the Neuropathy Impairment Score for Lower Limbs (p < 0.001) and its subscales (p < 0.023) compared with untreated subjects. There was significantly less deterioration among tafamidis-treated subjects compared with untreated subjects on the Norfolk Quality of Life scale (p < 0.001). There were no significant differences observed in functional (assessed by Karnofsky Performance Status Scale score) or nutritional (assessed by modified body mass index) status between the treated and untreated groups. The primary model which examined survival from baseline using the matched cohort was not able to yield estimates of the hazard ratio, as there were no deaths in the tafamidis-treated subjects. These findings support the results from clinical trials and strengthen evidence of the effectiveness of tafamidis beyond conventional clinical trials.

    The medium energy heavy ion accelerator (MEHIA) facility based on 14 UD Pelletron set up under the collaborative project of Bhabha Atomic Research Centre (BARC) and Tata Institute of Fundamental Research (TIFR) at the TIFR campus at Bombay has been serving as a joint BARC-TIFR facility for heavy-ion accelerator based research. As this accelerator has just completed five years of its successful operations, it has been thought to be an appropriate time to bring out a report of the research work carried out with the accelerator facility over these last five years. To put the research work in proper perspective, the present report is formatted to provide a short write-up highlighting the work carried out in each area of activity along with a list of the publications which have resulted from these investigations. Some theoretical work related to the experimental activities with the pelletron accelerator has also been included in the list of publications. The research work in the area of nuclear physics, which forms the main thrust of the research activities with the accelerator, covers areas of high spin states, high energy photons, resonances in heavy ion reactions, heavy ion elastic and transfer reactions, heavy ion fusion-fission reactions and radiochemical studies in heavy ion reactions. The interdisciplinary areas of research include condensed matter physics and accelerator based atomic physics. In addition to the above topics the present report also describes the work related to the pelletron accelerator and associated experimental facilities, gas detector development work, data acquisition systems and spectrometer for heavy recoil ions under development. The present status of the superconducting Linac booster project is also briefly described. (author). refs., tabs

    The Freund-Weinman multivariate exponential extension is generalized to the case of nonidentically distributed marginal distributions. A fatal shock model is given for the resulting distribution. Results in the bivariate case and the concept of constant multivariate hazard rate lead to a continuous distribution related to the multivariate exponential distribution (MVE) of Marshall and Olkin. This distribution is shown to be a special case of the extended Freund-Weinman distribution. A generalization of the bivariate model of Proschan and Sullo leads to a distribution which contains both the extended Freund-Weinman distribution and the MVE

    Ultrahigh energy cosmic rays carry information about their sources and the intervening medium apart from providing a beam of particles for studying certain features of high energy interactions currently inaccessible at man-made accelerators. They can at present be studied only via the extensive air showers (EAS's) they generate while passing through the Earth's atmosphere, since their fluxes are too low for the experiments of limited capability flown in balloons and satellites. The EAS is generated by a series of interactions of the primary cosmic ray and its progeny with the atmospheric nucle

    Objective The Osteoarthritis Initiative (OAI) is a multicentre study targeted at identifying biomarkers for evaluating the progression and risk factors of symptomatic knee OA. Here cartilage loss using 3 Tesla (3 T) MRI is analysed over 1 year in a subset of the OAI, together with its association with various risk factors. Methods An age- and gender-stratified subsample of the OAI progression subcohort (79 women and 77 men, mean (SD) age 60.9 (9.9) years, body mass index (BMI) 30.3 (4.7)) with both frequent symptoms and radiographic OA in at least one knee was studied. Coronal FLASHwe (fast low angle shot with water excitation) MRIs of the right knee were acquired at 3 T. Seven readers segmented tibial and femoral cartilages blinded to order of acquisition. Segmentations were quality controlled by one expert. Results The reduction in mean cartilage thickness (ThC) was greater (p = 0.004) in the medial than in the lateral compartment, greater (p = 0.001) in the medial femur (−1.9%) than in the medial tibia (−0.5%) and greater (p = 0.011) in the lateral tibia (−0.7%) than in the lateral femur (0.1%). Multifactorial analysis of variance did not reveal significant differences in the rate of change in ThC by sex, BMI, symptoms and radiographic knee OA status. Knees with Kellgren–Lawrence grade 2 or 3 and with a BMI >30 tended to display greater changes. Conclusions In this sample of the OAI progression subcohort, the greatest, but overall very modest, rate of cartilage loss was observed in the weight-bearing medial femoral condyle. Knees with radiographic OA in obese participants showed trends towards higher rates of change than those of other participants, but these trends did not reach statistical significance. PMID:18519425

    Full Text Available Abstract Background The prognosis for metastatic melanoma remains poor even with traditional decarbazine or interferon therapy. 5-year survival is markedly higher amongst patients undergoing metastatectomy. Unfortunately not all are suitable for metastatectomy. Alternative agents for systemic therapy have, to date, offered no greater rates of survival beyond traditional therapy. A toll-like receptor 9 agonist, PF-3512676 (formerly known as CPG 7909 is currently being evaluated for its potential. Case presentation We present the case of a 54-year-old Caucasian male with completely resected metastatic cutaneous melanoma after immunotherapy. The patient initially progressed during adjuvant high-dose interferon, with metastases to the liver, spleen, and pelvic lymph nodes. During an 18-month treatment period with PF-3512676 (formerly known as CPG 7909, a synthetic cytosine-phosphorothioate-guanine rich oligodeoxynucleotide, slow radiologic disease progression was demonstrated at the original disease sites. Subsequent excision of splenic and pelvic nodal metastases was performed, followed by resection of the liver metastases. Histologic examination of both hepatic and splenic melanoma metastases showed extensive necrosis. Subsequent disease-free status was demonstrated by serial positron emission tomography (PET. Conclusion Existing evidence from phase I/II trials suggests systemic treatment with PF-3512676 is capable of provoking a strong tumor-specific immune response and may account for the prolonged tumor control in this instance.

    1999-01-01

    At the NASA John H. Glenn Research Center at Lewis Field (formerly the Lewis Research Center), experimental research in aircraft and space propulsion systems is conducted in more than 100 test cells and laboratories. These facilities are supported by a central process air system that supplies high-volume, high-pressure compressed air and vacuum at various conditions that simulate altitude flight. Nearly 100,000 square feet of metalworking and specialized fabrication shops located on-site produce prototypes, models, and test hardware in support of experimental research operations. These activities, comprising numerous individual noise sources and operational scenarios, result in a varied and complex noise exposure environment, which is the responsibility of the Glenn Research Center Noise Exposure Management Program. Hearing conservation, community noise complaint response and noise control engineering services are included under the umbrella of this Program, which encompasses the Occupational Safety and Health Administration (OSHA) standard on occupational noise exposure, Sec. 29CFR 1910.95, as well as the more stringent NASA Health Standard on Hearing Conservation. Prior to 1994, in the absence of feasible engineering controls, strong emphasis had been placed on personal hearing protection as the primary mechanism for assuring compliance with Sec. 29CFR 1910.95 as well as NASA's more conservative policy, which prohibits unprotected exposure to noise levels above 85 dB(A). Center policy and prudent engineering practice required, however, that these efforts be extended to engineered noise controls in order to bring existing work areas into compliance with Sec. 29CFR 1910.95 and NASA's own policies and to ensure compliance for new installations. Coincident with the establishment in 1995 of a NASA wide multi-year commitment of funding for environmental abatement projects, the Noise Exposure Management Program was established, with its focus on engineering approaches

    2002-01-01

    Due to current social and economical framework, in last years many Member States (MS) started a process of Plant Life Extension (PLEX) for their older nuclear facilities. The process followed many different approaches, being intrinsically dependent on the national regulatory framework and technical tradition. This process has many nuclear safety implications, other than strategic and political ones, and therefore a need for tailoring the available safety assessment tools to such applications has become urgent in recent years. Typical safety assessment processes such as the Periodic Safety Review has been used already and can be used in the future as a framework for a PLEX. Also the review of regular maintenance and ageing management programs and the continuous upgrading of the Safety Analysis Report are tools widely used in a life extension context in many MS. However, recently some MS highlighted the need to identify in a clear way the technical aspects more directly affecting the decision for a long-term operation of a nuclear facility. Many Technical Cooperation projects have been requested for the year 2003-2004 on this subject and a generic task in Nuclear Safety proved necessary as a background activity. Therefore, on May 6-10, 2002, a Consultant Meeting dealing with Safety Aspects of life extension for NPPs was convened at the Nuclear Safety Dept. of the IAEA. It was attended by representatives of Regulatory Bodies and Utilities, both from countries with experience of life extension of NPPs and countries where the process is at the beginning. The main application problems were identified and discussed and a first attempt was carried out to define the key elements of the life extension process, isolating peculiar technical items, LTO related, from generic safety related tasks. The result was a preliminary technical document with a collection of basic experience and information for the implementation of a PLEX program. Therefore the draft document was thought

    The Savannah River Region Health Information System Birth Defects Registry (SRRHIS-BDR) began on September 30, 1994. As with the SRRHIS Cancer Registry, surveillance of the 12 Georgia counties was subcontracted to Emory University School of Public Health. Collaborative efforts between the Medical University of South Carolina (MUSC) and Emory University staffs have been characterized by warm relationships and commitment to developing a state of the art registry. As a result of early planning efforts, the authors were able to actually activate the data collection. As of the end of September 1995, partial data from the 1994 birth cohort and up-to-date data for the 1995 birth cohort had been collected on the South Carolina side. The Georgia Staff started later and have not yet caught up to the 1994 level. South Carolina was able to start earlier because they were fortunate to quickly recruit an abstractor. Also, by the end of the first year, an innovative automated data entry system for laptop computers was developed by the computer staff to facilitate and improve data collection

    The need for closer linkages between scientific and programmatic areas focused on addressing vaccine-preventable and acute respiratory infections led to establishment of the National Center for Immunization and Respiratory Diseases (NCIRD) at the Centers for Disease Control and Prevention. During its first 10 years (2006-2015), NCIRD worked with partners to improve preparedness and response to pandemic influenza and other emergent respiratory infections, provide an evidence base for addition of 7 newly recommended vaccines, and modernize vaccine distribution. Clinical tools were developed for improved conversations with parents, which helped sustain childhood immunization as a social norm. Coverage increased for vaccines to protect adolescents against pertussis, meningococcal meningitis, and human papillomavirus-associated cancers. NCIRD programs supported outbreak response for new respiratory pathogens and oversaw response of the Centers for Disease Control and Prevention to the 2009 influenza A(H1N1) pandemic. Other national public health institutes might also find closer linkages between epidemiology, laboratory, and immunization programs useful.

    The TORUS collaboration derives its name from the research it focuses on, namely the Theory of Reactions for Unstable iSotopes. It is a Topical Collaboration in Nuclear Theory, and funded by the Nuclear Theory Division of the Office of Nuclear Physics in the Office of Science of the Department of Energy. The funding supports one postdoctoral researcher for the years 1 through 3. The collaboration brings together as Principal Investigators a large fraction of the nuclear reaction theorists currently active within the USA. The mission of the TORUS Topical Collaboration is to develop new methods that will advance nuclear reaction theory for unstable isotopes by using three-body techniques to improve direct-reaction calculations, and, by using a new partial-fusion theory, to integrate descriptions of direct and compound-nucleus reactions. This multi-institution collaborative effort is directly relevant to three areas of interest: the properties of nuclei far from stability; microscopic studies of nuclear input parameters for astrophysics, and microscopic nuclear reaction theory.

  15. Lipid-Altering Therapies and the Progression of Atherosclerotic Disease

    International Nuclear Information System (INIS)

    Wierzbicki, Anthony S.

    2007-01-01

    Lipids play a key role in the progression of atherosclerosis, and lipid-lowering therapies have been studied for 30 years in coronary disease. Measurement of the progression of atherosclerosis through carotid intima-media thickness, coronary mean lumen diameter, and, mostly recently, intravascular ultrasound is generally accepted. This article reviews the role of lipid-lowering therapies in changing the rate of atherosclerosis progression in the coronary and carotid circulations. Statins are the primary therapy used to reduce atherosclerosis and cardiovascular events, including strokes and transient ischemic attacks, and have benefits in reducing events in patients undergoing carotid endarterectomy. In contrast, data for other agents, including fibrates and nicotinic acid, in reducing the progression of atherosclerosis are less extensive and not as well known. There is increasing interest in optimizing the whole lipid profile, as this might deliver extra benefits over and above statin therapy alone. Initial proof of this concept has recently come from studies that measured the progression of atherosclerosis and showed that adding nicotinic acid to statin therapy and, more directly, infusion of high-density lipoprotein-like particles reduced progression and indeed might induce regression of the disease. It is likely that the management of significant carotid stenosis will become ever more drug focused and will be customized to the lipid profile of each patient with intervention reserved only for late-stage symptomatic disease

    Childhood obesity is associated with abnormal glucose metabolism and type 2 diabetes mellitus (T2DM). This study evaluated the prevalence of abnormal glucose metabolism in asymptomatic obese children and adolescents, and determined the percentage of T2DM development after 3-6 years of follow-up. During 2007-2013, 177 obese children and adolescents who had normal fasting plasma glucose (FPG100 mg/dL) were given an oral glucose tolerance test (OGTT). The participants were classified into four groups: normal glucose tolerance (NGT), NGT-hyperinsulinemia (NGT-HI), impaired glucose tolerance (IGT), and diabetes mellitus (DM). Blood chemistries, including FPG, glycated hemoglobin, and lipid profiles, and liver function test were performed every 6-12 months or when the patient developed any symptom or sign indicative of diabetes. Glucose metabolism alterations were detected in 81.4% of the participants: 63.8% with NGT-HI, 15.3% with IGT, and 2.3% with T2DM. The median levels of homeostasis model assessment-insulin resistance (HOMA-IR) in patients with IGT (8.63) were significantly greater than those in the patients with NGT (4.04) (p1). During the follow-up, 22 patients (14.4%) developed T2DM significantly more from the IGT group (nine of 33 cases, 27.3%) than the NGT-HI group (12 of 108 cases, 11.1%) (p=0.022). The predicting parameters for T2DM conversion were weight status, body mass index (BMI), FBG, fasting insulin, alanine transaminase (ALT) levels, and HOMA-IR. Glucose metabolism alteration was commonly found among obese adolescents. Factors associated with T2DM development were greater weight status and the severity of insulin resistance as shown by higher HOMA-IR levels.

    Full Text Available Rather than a scientific text, the author contributes a concise memorandum from the originator of the idea who has managed the campaign for the conversion of the military barracks into a creative cluster between 1988 and 2002, when he parted ways with Metelkova due to conflicting views on the center’s future. His views shed light on a distant period of time from a perspective of a participant–observer. The information is abundantly supported by primary sources, also available online. However, some of the presented hypotheses are heavily influenced by his personal experiences of xenophobia, elitism, and predatorial behavior, which were already then discernible on the so-called alternative scene as well – so much so that they obstructed the implementation of progressive programs. The author claims that, in spite of the substantially different reality today, the myths and prejudices concerning Metelkova must be done away with in order to enhance its progressive nature. Above all, the paper calls for an objective view on internal antagonisms, mainly originating in deep class divisions between the users. These make a clear distinction between truly marginal ndividuals and the overambitious beau-bourgeois, as the author labels the large part of users of Metelkova of »his« time. On these grounds, he argues for a robust approach to ban all forms of xenophobia and self-ghettoization.

    The National Oceanic and Atmospheric Administration (NOAA) and National Aeronautics and Space Administration (NASA) are jointly acquiring the next-generation civilian weather and environmental satellite system: the Joint Polar Satellite System (JPSS). The Joint Polar Satellite System will replace the afternoon orbit component and ground processing system of the current Polar-orbiting Operational Environmental Satellites (POES) managed by NOAA. The JPSS satellites will carry a suite of sensors designed to collect meteorological, oceanographic, climatological and geophysical observations of the Earth. The ground processing system for JPSS is known as the JPSS Common Ground System (JPSS CGS). Developed and maintained by Raytheon Intelligence, Information and Services (IIS), the CGS is a multi-mission enterprise system serving NOAA, NASA and their national and international partners, such as NASA's Earth Observation System (EOS), NOAA's current POES, the Japan Aerospace Exploration Agency's (JAXA) Global Change Observation Mission - Water (GCOM-W1), and DoD's Defense Meteorological Satellite Program (DMSP). The CGS provides a wide range of support to a number of national and international missions, including command and control, mission management, data acquisition and routing, and environmental data processing and distribution. The current suite of CGS-supported missions has demonstrated the value of interagency and international partnerships to address global observation needs. With its established infrastructure and existing suite of missions, the CGS is extensible to a wider array of potential new missions. This paper will describe how the inherent scalability and extensibility of the CGS enables the addition of these new missions, with an eye on global enterprise needs in the 2020's and beyond.

  1. Rapidly Progressive Corticobasal Degeneration Syndrome

    2011-08-01

    Full Text Available Introduction: Corticobasal syndrome (CBS has a heterogeneous clinical presentation with no specific pathologic substratum. Its accurate diagnosis is a challenge for neurologists; in order to establish CBS definitively, postmortem confirmation is required. Some clinical and radiological features can help to distinguish it from other neurodegenerative conditions, such as Creutzfeldt-Jakob disease (CJD. Clinical Case: A 74-year-old woman presented with language impairment, difficulty in walking and poor attentiveness that had begun 10 days before. Other symptoms, such as asymmetrical extra-pyramidal dysfunction, limb dystonia and ‘alien limb’ phenomena, were established over the next 2 months, with rapid progression. Death occurred 3 months after symptom onset. Laboratory results were normal. Initially, imaging only showed restricted diffusion with bilateral parieto-occipital gyri involvement on DWI-MRI, with unspecific EEG changes. An autopsy was performed. Brain neuropathology confirmed sporadic CJD (sCJD. Conclusions: CBS is a heterogeneous clinical syndrome whose differential diagnosis is extensive. CJD can occasionally present with clinical characteristics resembling CBS. MRI detection of abnormalities in some sequences (FLAIR, DWI, as previously reported, has high diagnostic utility for sCJD diagnosis – especially in early stages – when other tests can still appear normal. Abnormalities on DWI sequencing may not correlate with neuropathological findings, suggesting a functional basis to explain the changes found.

    Brief statements on the progress of the design and construction of the HSX experiment are reported. Topics covered include the modular and auxiliary coil systems, the coil support structure, vacuum vessel, the ECH system, the magnet power supply and site. The proposed budget for Year 2 (August 1, 1994 through July 31, 1995) is presented. The effects of a flat funding profile (based on Year 2 budget level of $1137K) on out-years and the HSX project schedule are discussed. The stretching out of the program to accommodate the reduced funding profile should result in only a slight delay in HSX operations

    Fluorescein is a chemical dye frequently used in eye diseases to assess blood flow in the retina, choroid tissue, and iris. Although it has many known adverse effects, it has not previously been reported to lead to jaundice. The purpose of this case report was to emphasize that for patients presenting at the emergency department with jaundice symptoms, it should not be forgotten by emergency physicians that jaundice can develop after fluorescein angiography. Case: A 65-year-old woman presented at the emergency department with extensive jaundice that had developed on her entire body a few hours after fluorescein angiography applied because of vision impairment. The test results for all the diseases considered to cause jaundice were normal,and fluorescein-related jaundice was diagnosed. Conclusion: A detailed anamnesis should be taken when jaundice is seen in patients who have undergone fluorescein angiography, and it should not be forgotten that fluorescein dye is a rare cause of jaundice.

    The global extendibility of smooth causal geodesically incomplete spacetimes is investigated. Denote by {gamma} one of the incomplete non-extendible causal geodesics of a causal geodesically incomplete spacetime (M, g{sub ab}). First, it is shown that it is always possible to select a synchronized family of causal geodesics {Gamma} and an open neighbourhood U of a final segment of {gamma} in M such that U comprises members of {Gamma}, and suitable local coordinates can be defined everywhere on U provided that {gamma} does not terminate either on a tidal force tensor singularity or on a topological singularity. It is also shown that if, in addition, the spacetime (M, g{sub ab}) is globally hyperbolic, and the components of the curvature tensor, and its covariant derivatives up to order k - 1 are bounded on U, and also the line integrals of the components of the kth-order covariant derivatives are finite along the members of {Gamma}-where all the components are meant to be registered with respect to a synchronized frame field on U-then there exists a C{sup k-} extension {Phi} : (M,g{sub ab}) {yields}(M,g{sub ab}) so that for each {gamma}-bar from {Gamma}, which is inextendible in (M, g{sub ab}), the image, {Phi}{gamma}-bar, is extendible in (M,g{sub ab}). Finally, it is also proved that whenever {gamma} does terminate on a topological singularity (M, g{sub ab}) cannot be generic.

    Jefferson Lab's Web Extensible Display Manager (WEDM) allows staff to access EDM control system screens from a web browser in remote offices and from mobile devices. Native browser technologies are leveraged to avoid installing and managing software on remote clients such as browser plugins, tunnel applications, or an EDM environment. Since standard network ports are used firewall exceptions are minimized. To avoid security concerns from remote users modifying a control system, WEDM exposes read-only access and basic web authentication can be used to further restrict access. Updates of monitored EPICS channels are delivered via a Web Socket using a web gateway. The software translates EDM description files (denoted with the edl suffix) to HTML with Scalable Vector Graphics (SVG) following the EDM's edl file vector drawing rules to create faithful screen renderings. The WEDM server parses edl files and creates the HTML equivalent in real-time allowing existing screens to work without modification. Alternatively, the familiar drag and drop EDM screen creation tool can be used to create optimized screens sized specifically for smart phones and then rendered by WEDM.

    2014-03-01

    The history of interventional cardiology has been marked by several technologic revolutions since the late 1970s. The first key step was the use of inflatable balloon angioplasty as an alternative to CABG surgery for coronary revascularization, followed by intracoronary delivery of bare metal stent (BMS) and drug eluting stents (DES) to drastically reduce intracoronary restenosis observed with BMS. Improved stents platforms and polymers (absorbable or biocompatible) led to a dramatic reduction in the rate of late stent thrombosis. Self-expanding stents are now available to improve stent a position especially in acute myocardial infarction. The emergence of new fully bioabsorbable stents that can be combined with antiproliferative drugs is the ongoing revolution. A new generation of stents is continuously improving and likely to become the ideal stent for coronary revascularization in the near future. © 2014 médecine/sciences – Inserm.

    Energy generated by the world’s oceans and rivers offers the potential to make substantial contributions to the domestic and global renewable energy supply. However, the marine and hydrokinetic (MHK) energy industry faces challenges related to siting, permitting, construction, and operation of pilotand commercial-scale facilities. One of the challenges is to understand the potential effects to marine organisms from electromagnetic fields, which are produced as a by-product of transmitting power from offshore to onshore locations through underwater transmission cables. This report documents the progress of the third year of research (fiscal year 2012) to investigate environmental issues associated with marine and hydrokinetic energy (MHK) generation. This work was conducted by Pacific Northwest National Laboratory (PNNL) for the U.S. Department of Energy’s (DOE’s) Office of Energy Efficiency and Renewable Energy (EERE) Wind and Water Technologies Office. The report addresses the effects of electromagnetic fields (EMFs) on selected marine species where significant knowledge gaps exist. The species studied this fiscal year included one fish and two crustacean species: the Atlantic halibut (Hippoglossus hippoglossus), Dungeness crab (Metacarcinus magister), and American lobster (Homarus americanus).

    The CNSC has introduced the term Design Extension Conditions (DEC) in regulatory document RD-337 version 2, 'Design of New Nuclear Power Plants' which was issued for public consultation in July 2012. The primary drivers for this change compared with the earlier version of RD-337 are to maintain alignment with the equivalent International Atomic Energy Agency (IAEA) safety standard and to introduce changes resulting from lessons learned from the Fukushima Daiichi accident. RD-337 version 2 and the accompanying guidance document GD-337 establish high level design requirements and expectations for new Nuclear Power Plants (NPPs), including those pertaining to DEC. Other regulatory documents provide requirements for safety analysis and accident management as well as other aspect relevant to DEC. Nevertheless, the currently available guidance specific to DEC is not comprehensive, while the practices just begin to emerge. CNSC and industry stakeholders are actively discussing how the high level requirements and expectations will be applied in various fields. This paper is a summary of a CNSC discussion paper that is being developed to encourage substantive stakeholder discussions. The topic of DEC is being advanced rapidly both nationally and internationally. With this in mind, this paper does not intend to provide a final established position, but rather to stimulate discussion on the subject of DEC. This paper provides the definition of DEC, gives background information relating to the adoption of the term, describes the identification of DECs and the underlying principles associated with design, analysis, operational and procedural requirements. As described in this paper, DEC and associated requirements apply to new NPPs. Applicability to existing NPPs is also discussed. (author)

    Full Text Available The Business Process Execution Language (BPEL has emerged as de-facto standard for business processes implementation. This language is designed to be extensible for including additional valuable features in a standardized manner. There are a number of BPEL extensions available. They are, however, neither classified nor evaluated with respect to their compliance to the BPEL standard. This article fills this gap by providing a framework for classifying BPEL extensions, a classification of existing extensions, and a guideline for designing BPEL extensions.

    A session-based process satisfies the progress property if its sessions never get stuck when it is executed in an adequate context. Previous work studied how to define progress by introducing the notion of catalysers, execution contexts generated from the type of a process. In this paper, we refine...... such definition to capture a more intuitive notion of context adequacy for checking progress. Interestingly, our new catalysers lead to a novel characterisation of progress in terms of the standard notion of lock-freedom. Guided by this discovery, we also develop a conservative extension of catalysers that does...
