    Clinical Physiology Grand Rounds (CPGR) is an interactive, case-based conference for medical students designed to: (1) integrate preclinical and clinical learning; (2) promote inductive clinical reasoning; and (3) emphasise students as peer teachers. CPGR specifically encourages mixed learning level student interactions and emphasises the use of concept mapping. We describe the theoretical basis and logistical considerations for an interactive, integrative, mixed-learner environment such as CPGR. In addition, we report qualitative data regarding students' attitudes towards and perceptions of CPGR. Medical students from first to fourth year participate in a monthly, interactive conference. The CPGR was designed to bridge gaps and reinforce linkages between basic science and clinical concepts, and to incorporate interactive vertical integration between preclinical and clinical students. Medical education and content experts use Socratic, interactive teaching methods to develop real-time concept maps to emphasise the presence and importance of linkages across curricula. Student focus groups were held to assess attitudes towards and perceptions of the mixed-learner environment and concept maps in CPGR. Qualitative analyses of focus group transcripts were performed to develop themes and codes describing the students' impressions of CPGR. CPGR is a case-based, interactive conference designed to help students gain an increased appreciation of linkages between basic science and clinical medicine concepts, and an increased awareness of clinical reasoning thought processes. Success is dependent upon explicit attention being given to goals for students' integrated learning. © Blackwell Publishing Ltd 2013.

    The Telemedicine Spacebridge to Moscow was a series of intercontinental sessions sponsored jointly by NASA and the Moscow Academy of Medicine. To improve the quality of medical images presented, the MDIS Project developed a workstation for acquisition, storage, and interactive display of radiology and pathology images. The workstation was based on a Macintosh IIfx platform with a laser digitizer for radiographs and video capture capability for microscope images. Images were transmitted via the Russian Lyoutch Satellite which had only a single video channel available and no high speed data channels. Two workstations were configured -- one for use at the Uniformed Services University of Health Sciences in Bethesda, MD. and the other for use at the Hospital of the Interior in Moscow, Russia. The two workstations were used may times during 16 sessions. As clinicians used the systems, we modified the original configuration to improve interactive use. This project demonstrated that numerous acquisition and output devices could be brought together in a single interactive workstation. The video images were satisfactory for remote consultation in a grand rounds format.

    Grand Rounds is a ritual of medical education and inpatient care comprised of presenting the medical problems and treatment of a patient to an audience of physicians, residents, and medical students. Traditionally, the patient would be in attendance for the presentation and would answer questions. Grand Rounds has evolved considerably over the years with most sessions being didactic-rarely having a patient present (although, in some instances, an actor will portray the patient). Other members of the team, such as nurses, nurse practitioners, and biomedical engineers, are not traditionally involved in the formal teaching process. In this study we examine the rapid ideation in a clinical setting to forge a system of cross talk between engineers and physicians as a steady state at the praxis of ideation and implementation.

    Multidisciplinary grand rounds provides an opportunity to promote excellence in patient care through scholarly presentations and interdisciplinary collaboration with an innovative approach. In addition, multidisciplinary grand rounds serves to recognize expertise of staff, mentor and support professional development, and provide a collaborative environment across all clinical disciplines and support services. This article describes a process model developed by nurse educators for implementing a multidisciplinary grand rounds program. The components of the process model include topic submissions, coaching presenters, presentations, evaluations, and spreading the work. This model can be easily implemented at any organization.

    Full Text Available Abstract Background Although grand rounds plays a major educational role at academic medical centers, there has been little investigation into the factors influencing the learners' decision to attend. Greater awareness of attendees' expectations may allow grand rounds planners to better accommodate the learners' perspective, potentially making continuing education activities more attractive and inviting. Methods We used both qualitative (part A and quantitative (part B techniques to investigate the motivators and barriers to grand rounds attendance. Part A investigated contextual factors influencing attendance as expressed through attendee interviews. Transcripts of the interviews were analyzed using grounded theory techniques. We created a concept map linking key factors and their relationships. In part B we quantified the motivators and barriers identified during the initial interviews through a survey of the grand rounds audience. Results Sixteen persons voluntarily took part in the qualitative study (part A by participating in one of seven group interview sessions. Of the 14 themes that emerged from these sessions, the most frequent factors motivating attendance involved competent practice and the need to know. All sessions discussed intellectual stimulation, social interaction, time constraints and convenience, licensure, content and format, and absence of cost for attending sessions. The 59 respondents to the survey (part B identified clinically-useful topics (85%, continuing education credit (46%, cutting-edge research (27%, networking (22%, and refreshments (8% as motivators and non-relevant topics (44% and too busy to attend (56% as barriers. Conclusion Greater understanding of the consumers' perspective can allow planners to tailor the style, content, and logistics to make grand rounds more attractive and inviting.

    Full Text Available With the emerging trend of patient family–centered care in health care, it is essential that physicians be exposed to patient and family perspectives of care during medical education and training. Grand Rounds provides an ideal format for physicians to learn about patient family–centered care. At Brigham and Women’s Hospital, we sought to bring the voice of the patient to Patient Family–Centered Grand Rounds in order to expose clinicians to rich narratives describing the medical care received by patients/families and to ultimately change physician practice to reflect patient family–centered principles. We conducted a clinician survey and found promising results indicating that patient/family narratives can be effective at educating physicians about patient family–centered care.

    Introduction: Diagnostic reasoning is a core skill in teaching and learning in undergraduate curricula. Diagnostic grand rounds (DGRs) as a subform of grand rounds are intended to train the students' skills in the selection of appropriate tests and in the interpretation of test results. The aim of this study was to test DGRs for their ability to improve diagnostic reasoning by using a pre-post-test design. Methods: During one winter term, all 398 fifth-year students (36.1% male, 63.9% female) solved 23 clinical cases presented in 8 DGRs. In an online questionnaire, a Diagnostic Thinking Inventory (DTI) with 41 items was evaluated for flexibility in thinking and structure of knowledge in memory. Results were correlated with those from a summative multiple-choice knowledge test and of the learning objectives in a logbook. Results: The students' DTI scores in the post-test were significantly higher than those reported in the pre-test. DTI scores at either testing time did not correlate with medical knowledge as assessed by a multiple-choice knowledge test. Abilities acquired during clinical clerkships as documented in a logbook could only account for a small proportion of the increase in the flexibility subscale score. This effect still remained significant after accounting for potential confounders. Conclusion: Establishing DGRs proofed to be an effective way of successfully improving both students' diagnostic reasoning and the ability to select the appropriate test method in routine clinical practice.

    Full Text Available Audience: The eConference is an interactive video conference grand rounds innovation to augment the didactic curriculum provided for medical students, interns, residents, fellows, and attending physicians. Introduction: Formal education during emergency medicine (EM training has historically emphasized aspects of humanism and constructivism; the former through self-directed reading in books and journals, the latter through the content and discussion during resident didactics.1 However, some studies suggest that the current generation of EM learners are increasingly using digital and internet technologies to connect with online peer networks, a phenomenon known as connectivism.2 As such, contemporary EM learners are increasingly utilizing social media and Free Open Access Medical Education (FOAM to supplement traditional learning resources. The eConference was developed to be an interactive, virtual grand rounds that marries the merits of constructivism with connectivism; a new format of EM didactics that goes beyond the “typical lecture” model to incorporate the changing landscape in technology and medical education by combining classroom teaching at multiple institutions alongside digital learning tools. This manuscript outlines how to plan and execute a joint video conference with another institution. Objectives: Our objectives were to create and implement a novel virtual conference format through the integration of social media tools which allows for interdisciplinary and multi-site participation to enhance EM resident education. We wish to outline the steps required to reproduce this innovative session and share lessons learned. Conclusion: We designed and executed a multi-centered, novel form of virtual conference into the EM residency curriculum at two participating institutions. The virtual conference took place during a routine conference day for both programs, an hour in duration. The format utilized a hybrid of live and virtual

    Gender bias has been identified as one of the drivers of gender disparity in academic medicine. Bias may be reinforced by gender subordinating language or differential use of formality in forms of address. Professional titles may influence the perceived expertise and authority of the referenced individual. The objective of this study is to examine how professional titles were used in the same and mixed-gender speaker introductions at Internal Medicine Grand Rounds (IMGR). A retrospective observational study of video-archived speaker introductions at consecutive IMGR was conducted at two different locations (Arizona, Minnesota) of an academic medical center. Introducers and speakers at IMGR were physician and scientist peers holding MD, PhD, or MD/PhD degrees. The primary outcome was whether or not a speaker's professional title was used during the first form of address during speaker introductions at IMGR. As secondary outcomes, we evaluated whether or not the speakers professional title was used in any form of address during the introduction. Three hundred twenty-one forms of address were analyzed. Female introducers were more likely to use professional titles when introducing any speaker during the first form of address compared with male introducers (96.2% [102/106] vs. 65.6% [141/215]; p form of address 97.8% (45/46) compared with male dyads who utilized a formal title 72.4% (110/152) of the time (p = 0.007). In mixed-gender dyads, where the introducer was female and speaker male, formal titles were used 95.0% (57/60) of the time. Male introducers of female speakers utilized professional titles 49.2% (31/63) of the time (p addressed by professional title than were men introduced by men. Differential formality in speaker introductions may amplify isolation, marginalization, and professional discomfiture expressed by women faculty in academic medicine.

    To determine whether use of self-assessment (SA) questions affects the effectiveness of weekly didactic grand rounds presentations. From 26 consecutive grand rounds presentations from August 2013 to April 2014, a 52-question multiple-choice test was administered based on 2 questions from each presentation. Community teaching institution. General surgery residents, students, and attending physicians. The test was administered to 66 participants. The mean score was 41.8%. There was no difference in test score based on experience with similar scores for junior residents, senior residents, and attending surgeons (43%, 46%, and 44%; p = 0.13). Most participants felt they would be most interested in presentations directly related to their surgical specialty. Participants, however, did not score differently on topics which were the focus of the program (40% vs. 42%; p = 0.85). Journal club presentations (39% vs. others 42%; p = 0.33) also did not affect the score. The Pearson correlation coefficient for attendance was 0.49 (p < 0.0001) demonstrated that attendance was very important. Participation in the weekly SA was significantly associated with improved score as those who participated in SA scored over 20% higher than those who did not (59% vs. 38%; p < 0.0001). Based on multiple linear regression for mean score, SA explained the variation in score more than attendance. The current study found that without preparation approximately 40% of material presented is retained after 10 months. Participation in weekly SA significantly improved retention of information from grand rounds presentations. Copyright © 2016 Association of Program Directors in Surgery. Published by Elsevier Inc.

    Neuroscience grand rounds (NSGR) is a key educational exercise in most academic medical centers. Despite its importance, there are few published studies evaluating the manner in which it is conducted. Our objective was to obtain consensus opinion from staff neurologists, neurosurgeons, neuroradiologists, and neuropathologists on the features that best characterize a highly educational NSGR. Using the Delphi technique, multiple rounds of questionnaires were presented to a panel of neurologists, neurosurgeons, neuropathologists, and neuroradiologists. The anonymous responses were analyzed and fed back to participants. Each round, the participants were given the opportunity to react to collective opinion by changing their response or by presenting arguments in favor or against the item in question. We found that support for NSGR in its present form is high and that particularly strong support exists for 1) case-based rounds, 2) high level of audience interaction, 3) resident participation in case presentation and analysis, 4) formal training for residents in leading case-based presentations, and 5) resident feedback and evaluation. Our results offer centers that use a case-based format for NSGR with guidance to maximize the important learning opportunity that it provides. We provide an organized evaluation of expert opinion on how this important educational exercise should be conducted. The results expose some fresh insights into traditional values in medical education.

    A national needs assessment of radiology program directors was performed to characterize grand rounds (GR) programs, assess the perceived educational value of GR programs, and determine the impact of the recent economic downturn on GR. A 28-question survey was developed querying the organizational logistics of GR programs, types of speakers, content of talks, honoraria, types of speakers invited, response to the economic downturn, types of speaker interaction with residents, and perceived educational value of GR. Questions were in multiple-choice, yes-or-no, and five-point Likert-type formats. The survey was distributed to the program directors of all radiology residencies within the United States. Fifty-seven of 163 programs responded, resulting in a response rate of 36%. Thirty-eight programs (67%) were university residencies and 10 (18%) were university affiliated. Eighty-two percent of university and 60% of university-affiliated residencies had their own GR programs, while only 14% of community and no military residencies held GR. GR were held weekly in 18% of programs, biweekly in 8%, monthly in 42%, bimonthly in 16%, and less frequently than every 2 months in 16%. All 38 programs hosting GR reported a broad spectrum of presentations, including talks on medical education (66%), clinical and evidence-based medicine (55%), professionalism (45%), ethics (45%), quality assurance (34%), global health (26%), and resident presentations (26%). All programs invited speakers from outside the institution, but there was variability with regard to the frequency of visits and whether invited speakers were from out of town. As a result of recent economic events, one radiology residency (3%) completely canceled its GR program. Others decreased the number of speakers from outside their cities (40%) or decreased the number of speakers from within their own cities (16%). Honoraria were paid to speakers by 95% of responding programs. Most program directors (79%) who had their own

    During the 20th century, use of tobacco products contributed to the deaths of 100 million persons worldwide. In 2011, approximately 6 million additional deaths were linked to tobacco use, the world's leading underlying cause of death, responsible for more deaths each year than human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS), tuberculosis, and malaria combined. One third to one half of lifetime users die from tobacco products, and smokers die an average of 14 years earlier than nonsmokers. Manufactured cigarettes account for 96% of all tobacco sales worldwide. From 1880 to 2009, annual global consumption of cigarettes increased from an estimated 10 billion cigarettes to approximately 5.9 trillion cigarettes, with five countries accounting for 58% of the total consumption: China (38%), Russia (7%), the United States (5%), Indonesia (4%), and Japan (4%). Among the estimated 1 billion smokers worldwide, men outnumber women by four to one. In 14 countries, at least 50% of men smoke, whereas in more than half of these same countries, fewer than 10% of women smoke. If current trends persist, an estimated 500 million persons alive today will die from use of tobacco products. By 2030, tobacco use will result in the deaths of approximately 8 million persons worldwide each year. Yet, every death from tobacco products is preventable.

    Full text: The goal of nuclear forensics is to develop a preferred approach to illicit trafficking investigations. This approach must be widely understood and acceptable as credible. The principle objectives of the Round Robin Test are to prioritize the forensic techniques and methods, evaluate attribution capabilities, and examine the utility of database. The Plutonium Round Robin has made a tremendous contribution to fulfilling these goals through a collaborative learning experience that resulted from the outstanding efforts of the six participating international laboratories. A prioritize list of techniques and methods has been developed based on this exercise. Future work will focus on a Highly Enriched Round Robin and extent to which the techniques and methods can be generalized. The Plutonium Round Robin demonstrated a rather high level of capability to determine the important characteristics of the materials and processes using analytical methods. When this capability to was combined with the appropriate knowledge and database, it resulted in a demonstrated capability to attribute the source of the materials to a specific nuclear fuel, reactor, and reprocessing facility. A number of shortfalls were also identified in our current capabilities. These included alternative dating techniques. Light Water Reactor discrimination techniques, and the lack of a comprehensive network of data/knowledge bases. The result of the Round Robin will be used to develop guidelines or a 'recommended protocol' to be made available to the interested authorities and countries to use in real cases. The poster will present a summary of the results of the Plutonium Round Robin and describe the plans the subsequent Highly Enriched Uranium Round Robin Test. (author)

    When rounding error is large relative to weighing error, it cannot be ignored when estimating scale precision and bias from calibration data. Further, if the data grouping is coarse, rounding error is correlated with weighing error and may also have a mean quite different from zero. These facts are taken into account in a moment estimation method. A copy of the program listing for the MERDA program that provides moment estimates is available from the author. Experience suggests that if the data fall into four or more cells or groups, it is not necessary to apply the moment estimation method. Rather, the estimate given by equation (3) is valid in this instance. 5 tables

    The piping inspection round robin was conducted in 1981 at the Pacific Northwest National Laboratory (PNNL) to quantify the capability of ultrasonics for inservice inspection and to address some aspects of reliability for this type of nondestructive evaluation (NDE). The round robin measured the crack detection capabilities of seven field inspection teams who employed procedures that met or exceeded the 1977 edition through the 1978 addenda of the American Society of Mechanical Engineers (ASME) Section 11 Code requirements. Three different types of materials were employed in the study (cast stainless steel, clad ferritic, and wrought stainless steel), and two different types of flaws were implanted into the specimens (intergranular stress corrosion cracks (IGSCCs) and thermal fatigue cracks (TFCs)). When considering near-side inspection, far-side inspection, and false call rate, the overall performance was found to be best in clad ferritic, less effective in wrought stainless steel and the worst in cast stainless steel. Depth sizing performance showed little correlation with the true crack depths

    The ward round has been a central activity of hospital life for hundreds of years. It is hardly mentioned in textbooks. The ward round is a parade through the hospital of professionals where most decision making concerning patient care is made. However the traditional format may be intimidating for patients and inadequate for communication. The round provides an opportunity for the multi-disciplinary team to listen to the patient\\'s narrative and jointly interpret his concerns. From this unfolds diagnosis, management plans, prognosis formation and the opportunity to explore social, psychological, rehabilitation and placement issues. Physical examination of the patient at the bedside still remains important. It has been a tradition to discuss the patient at the bedside but sensitive matters especially of uncertainty may better be discussed elsewhere. The senior doctor as round leader must seek the input of nursing whose observations may be under-appreciated due to traditional professional hierarchy. Reductions in the working hours of junior doctors and shortened length of stay have reduced continuity of patient care. This increases the importance of senior staff in ensuring continuity of care and the need for the joint round as the focus of optimal decision making. The traditional round incorporates teaching but patient\\'s right to privacy and their preferences must be respected. The quality and form of the clinical note is underreported but the electronic record is slow to being accepted. The traditional multi-disciplinary round is disappearing in some centres. This may be regrettable. The anatomy and optimal functioning of the ward round deserves scientific scrutiny and experimentation.

    In this talk I discuss the present status of these theories and of their observational and experimental implications. In section II, I briefly review the standard SU 3 sup(c) x SU 2 x U 1 model of the strong and electroweak interactions. Although phenomenologically successful, the standard model leaves many questions unanswered. Some of these questions are addressed by grand unified theories, which are defined and discussed in Section III. The Georgi-Glashow SU 5 model is described, as are theories based on larger groups such as SO 10 , E 6 , or SO 16 . It is emphasized that there are many possible grand unified theories and that it is an experimental problem not only to test the basic ideas but to discriminate between models. (orig./HSI)

    Phenomenologically appealing supersymmetric grand unified theories have large gauge representations and thus are not asymptotically free. Their ultraviolet validity is limited by the appearance of a Landau pole well before the Planck scale. One could hope that these theories save themselves, before the inclusion of gravity, by generating an interacting ultraviolet fixed point, similar to the one recently discovered in non-supersymmetric gauge-Yukawa theories. Employing a-maximization, a-theorem, unitarity bounds, as well as positivity of other central charges we nonperturbatively rule out this possibility for a broad class of prime candidates of phenomenologically relevant supersymmetric grand unified theories. We also uncover candidates passing these tests, which have either exotic matter or contain one field decoupled from the superpotential. The latter class of theories contains a model with the minimal matter content required by phenomenology.

    Total reflection x-ray fluorescence spectroscopy (TXRF) is used extensively to measure the quantity of ultra trace metal contamination on wafer surfaces for manufacture monitoring, tool and material qualification and process development in the semiconductor industry. It has been noted, however, that issues with TXRF instrument calibration using reference wafers may lead to difficulty in comparison of TXRF areal density results from different laboratories. In order to cross-calibrate TXRF instruments within Lucent Technologies, a set of reference wafers was produced and characterized. The reference wafers were then measured, in round robin fashion, on various TXRF instruments, internal and external to Lucent Technologies, and the results compared. The results will be discussed as well as implications for instances where TXRF data from different facilities must be compared in a meaningful manner. (author)

    The Second International Conference and Advanced School 'Turbulent Mixing and Beyond', TMB-2009, was held at the Abdus Salam International Centre for Theoretical Physics, (ICTP), Trieste, Italy on 27 July-7 August 2009. TMB-2009 united over 180 participants ranging from students to members of the National Academies of Sciences and Engineering, and including researchers at experienced and early stages of their carriers from leading scientific institutions in academia, national laboratories, corporations and industry worldwide. Responding to the community's inquiry and reaffirming the practices established at TMB-2007, two Round Tables were organized for the participants of TMB-2009 on 30 July 2009 and 6 August 2009 in the Oppenheimer Room at the Centre. The goals of the Round Tables were to encourage the information exchange among the members of the interdisciplinary and international TMB community, promote discussions regarding the state-of-the-art in TMB-related scientific areas, identify directions for frontier research, and articulate recommendations for future developments. This article is a summary of the collective work of the Round Table participants (listed alphabetically below by their last names), whose contributions form its substance and, as such, are greatly appreciated.

    Gauler, Allen L.; Pasieka, Donald F.

    1983-01-01

    A ball mounting fixture for a roundness gage is disclosed. The fixture includes a pair of chuck assemblies oriented substantially transversely with respect to one another and mounted on a common base. Each chuck assembly preferably includes a rotary stage and a wobble plate affixed thereto. A ball chuck affixed to each wobble plate is operable to selectively support a ball to be measured for roundness, with the wobble plate permitting the ball chuck to be tilted to center the ball on the axis of rotation of the rotary stage. In a preferred embodiment, each chuck assembly includes a vacuum chuck operable to selectively support the ball to be measured for roundness. The mounting fixture enables a series of roundness measurements to be taken with a conventional rotating gagehead roundness instrument, which measurements can be utilized to determine the sphericity of the ball.

  12. Cassini's Grand Finale Overview

    2017-12-01

    After 13 years in orbit, the Cassini-Huygens Mission to Saturn ended in a science-rich blaze of glory. Cassini sent back its final bits of unique science data on September 15, 2017, as it plunged into Saturn's atmosphere, vaporizing and satisfying planetary protection requirements. Cassini's final phase covered roughly ten months and ended with the first time exploration of the region between the rings and planet. In late 2016 Cassini transitioned to a series of 20 Ring Grazing orbits with peripases just outside Saturn's F ring, providing close flybys of tiny ring moons, including Pan, Daphnis and Atlas, and high-resolution views of Saturn's A and F rings. A final Titan flyby in late April 2017 propelled Cassini across Saturn's main rings and into its Grand Finale orbits. Comprised of 22 orbits, Cassini repeatedly dove between Saturn's innermost rings and upper atmosphere to answer fundamental questions unattainable earlier in the mission. The last orbit turned the spacecraft into the first Saturn atmosphere probe. The Grand Finale orbits provided highest resolution observations of both the rings and Saturn, and in-situ sampling of the ring particle composition, Saturn's atmosphere, plasma, and innermost radiation belts. The gravitational field was measured to unprecedented accuracy, providing information on the interior structure of the planet, winds in the deeper atmosphere, and mass of the rings. The magnetic field provided insight into the physical nature of the magnetic dynamo and structure of the internal magnetic field. The ion and neutral mass spectrometer sampled the upper atmosphere for molecules that escape the atmosphere in addition to molecules originating from the rings. The cosmic dust analyzer directly sampled the composition from different parts of the main rings for the first time. Fields and particles instruments directly measured the plasma environment between the rings and planet. Science highlights and new mysteries collected in the Grand

  13. Grand unification and supergravity

    International Nuclear Information System (INIS)

    Nanopoulos, D.V.

    Grand Unified Theories (GUTs) are very successful, but they suffer from fine-tuning or hierarchy problems. It seems that more symmetry beyond the gauge symmetry is needed and indeed supersymmetric GUTs may provide the correct framework in solving the hierarchy problems. These are reviewed. From the results discussed, it is seen that for the first time in particle physics, gravity seems to play a dominant role. It may be responsible for GUT breaking, SU(2) x U(1) breaking, fermion masses, proton decay and a consistent cosmological picture. Supergravity seems to offer a consistent, effective theory for energies below the Planck scale to N=1 local SUSY but also, in the context of N=8 extended supergravity with a dynamically realized SU(8), there may be a consistent fundamental unified theory of all interactions.

    Georgi, H.

    1983-01-01

    Grand unification is reviewed with regard to the flavor puzzle and the hierarchy puzzle. Progress in CP and the PQWWKDFS axion is reviewed. The neutrino mass and B-L research, the understanding and assimilation of the language of effective theories (which divide the momentum scale up into regions), with focus on the models, are surveyed. Various unified models are organized according to whether they address the hierarchy puzzle or the flavor puzzle. SU(5), SO(10), E6, and Higgs are considered simple and explicit models. Global symmetry addresses hierarchy puzzle, but the rules are unclear. In SO (18), with regard to hierarchy, perturbation theory breaks down. SO (14) fails for hierarchy because of GIM, b and t problems. Supersymmetry and technicolor with regard to flavor puzzle are questioned. The CP solution of ETC and Composite C models (addressing both flavor and hierarchy) is a minus. Composite A model has no evident virtues, and the basic idea of ETC model needs checking

  18. Neurobehavioral Grand Rounds introduction: Does near drowning in ice water prevent anoxic induced brain injury?

    Science.gov (United States)

    Hopkins, Ramona O

    2008-07-01

    Cold water near-drowning is often thought to be neuroprotective in individuals with anoxia of a longer duration than that usually required to produce irreversible neurologic damage. There is a paucity of data in adults with cold water near-drowning that assess neuropsychological outcomes. Information regarding long-term effects of near cold water near-drowning on neuropathology, neuropsychological and neurobehavioral outcomes are uncommon. This paper provides an introduction to two cases of cold water near-drowning reported in this issue of JINS by Sameulson and colleagues and provides background information for interpretation of the findings of these cases in the context of outcomes following anoxia.

    Adherence to prescribed medications is associated with improved clinical outcomes for chronic disease management and reduced mortality from chronic conditions (1). Conversely, nonadherence is associated with higher rates of hospital admissions, suboptimal health outcomes, increased morbidity and mortality, and increased health care costs (2). In the United States, 3.8 billion prescriptions are written annually (3). Approximately one in five new prescriptions are never filled, and among those filled, approximately 50% are taken incorrectly, particularly with regard to timing, dosage, frequency, and duration (4). Whereas rates of nonadherence across the United States have remained relatively stable, direct health care costs associated with nonadherence have grown to approximately $100-$300 billion of U.S. health care dollars spent annually (5,6). Improving medication adherence is a public health priority and could reduce the economic and health burdens of many diseases and chronic conditions (7).

    2014-01-17

    Intimate partner violence (IPV) is a serious, and preventable, public health problem in the United States. IPV can involve physical and sexual violence, threats of physical or sexual violence, and psychological abuse, including stalking. It can occur within opposite-sex or same-sex couples and can range from one incident to an ongoing pattern of violence. On average, 24 persons per minute are victims of rape, physical violence, or stalking by an intimate partner in the United States. These numbers underestimate the problem because many victims do not report IPV to police, friends, or families. In 2010, IPV contributed to 1,295 deaths, accounting for 10% of all homicides for that year. The combined medical, mental health, and lost productivity costs of IPV against women are estimated to exceed $8.3 billion per year. In addition to the economic burden of IPV, victims are more likely to experience adverse health outcomes, such as depression, anxiety, posttraumatic stress disorder symptoms, suicidal behavior, sexually transmitted infections, and unintended pregnancy.

    2017-12-05

    Aspirin exerts antiplatelet effects through irreversible inhibition of cyclooxygenase-1, whereas its anticancer effects may be due to inhibition of cyclooxygenase-2 and other pathways. In 2009, the U.S. Preventive Services Task Force endorsed aspirin for primary prevention of cardiovascular disease. However, aspirin's role in cancer prevention is still emerging, and no groups currently recommend its use for this purpose. To help physicians balance the benefits and harms of aspirin in primary disease prevention, the Task Force issued a guideline titled, "Aspirin Use for the Primary Prevention of Cardiovascular Disease and Colorectal Cancer" in 2016. In the evidence review conducted for the guideline, cardiovascular disease mortality and colorectal cancer mortality were significantly reduced among persons taking aspirin. However, there was no difference in nonfatal stroke, cardiovascular disease mortality, or all-cause mortality, nor in total cancer mortality, among those taking aspirin. Aspirin users were found to be at increased risk for major gastrointestinal bleeding. In this Beyond the Guidelines, the guideline is reviewed and 2 experts discuss how they would apply it to a 57-year-old man considering starting aspirin for primary prevention. Our experts review the data on which the guideline is based, discuss how they would balance the benefits and harms of aspirin therapy, and explain how they would incorporate shared decision making into clinical practice.

  2. Statistical grand rounds: understanding the mechanism: mediation analysis in randomized and nonrandomized studies.

    Science.gov (United States)

    Mascha, Edward J; Dalton, Jarrod E; Kurz, Andrea; Saager, Leif

    2013-10-01

    In comparative clinical studies, a common goal is to assess whether an exposure, or intervention, affects the outcome of interest. However, just as important is to understand the mechanism(s) for how the intervention affects outcome. For example, if preoperative anemia was shown to increase the risk of postoperative complications by 15%, it would be important to quantify how much of that effect was due to patients receiving intraoperative transfusions. Mediation analysis attempts to quantify how much, if any, of the effect of an intervention on outcome goes though prespecified mediator, or "mechanism" variable(s), that is, variables sitting on the causal pathway between exposure and outcome. Effects of an exposure on outcome can thus be divided into direct and indirect, or mediated, effects. Mediation is claimed when 2 conditions are true: the exposure affects the mediator and the mediator (adjusting for the exposure) affects the outcome. Understanding how an intervention affects outcome can validate or invalidate one's original hypothesis and also facilitate further research to modify the responsible factors, and thus improve patient outcome. We discuss the proper design and analysis of studies investigating mediation, including the importance of distinguishing mediator variables from confounding variables, the challenge of identifying potential mediators when the exposure is chronic versus acute, and the requirements for claiming mediation. Simple designs are considered, as well as those containing multiple mediators, multiple outcomes, and mixed data types. Methods are illustrated with data collected by the National Surgical Quality Improvement Project (NSQIP) and utilized in a companion paper which assessed the effects of preoperative anemic status on postoperative outcomes.

    Approximately 100,000 Americans have sickle cell disease (SCD), a group of recessively inherited red blood cell disorders characterized by abnormal hemoglobin, called hemoglobin S or sickle hemoglobin, in the red blood cells. Persons with hemoglobin SS or hemoglobin Sß 0 thalassemia, also known as sickle cell anemia (SCA), have the most severe form of SCD. Hemoglobin SC disease and hemoglobin Sß + thalassemia are other common forms of SCD. Red blood cells that contain sickle hemoglobin are inflexible and can stick to vessel walls, causing a blockage that slows or stops blood flow. When this happens, oxygen cannot reach nearby tissues, leading to attacks of sudden, severe pain, called pain crises, which are the clinical hallmark of SCD. The red cell sickling and poor oxygen delivery can also cause damage to the brain, spleen, eyes, lungs, liver, and multiple other organs and organ systems. These chronic complications can lead to increased morbidity, early mortality, or both. Tremendous strides in treating and preventing the complications of SCD have extended life expectancy. Now, nearly 95% of persons born with SCD in the United States reach age 18 years (1); however, adults with the most severe forms of SCD have a life span that is 20-30 years shorter than that of persons without SCD (2).

    In this study, we argue that contemporary nursing care has been overtaken by new public management strategies aimed at curtailing budgets in the public hospital sector in Australia. Drawing on qualitative interviews with 15 nurses from one public acute hospital with supporting documentary evidence, we demonstrate what happens to nursing work when management imposes rounding as a risk reduction strategy. In the case study outlined rounding was introduced across all wards in response to missed care, which in turn arose as a result of work intensification produced by efficiency, productivity, effectiveness and accountability demands. Rounding is a commercially sponsored practice consistent with new public management. Our study illustrates the impact that new public management strategies such as rounding have on how nurses work, both in terms of work intensity and in who controls their labour. © 2015 John Wiley & Sons Ltd.

    There are various causes of a painful palpable mass in the groin during pregnancy. The differential diagnoses of an inguinal mass include hernia, lymphadenopathy, mesothelial cyst, cystic lymphangioma, neoplasms (lipoma, leiomyoma and sarcoma), endometriosis, embryonic remnants and round ligament varicosities. Among them, round ligament varicosities can be easily misdiagnosed as an inguinal hernia in a pregnant woman. These lesions should be managed conservatively because they resolve spontaneously during the postpartum period. Ultrasonography can help make the diagnosis of round ligament varicosities and so prevent unnecessary surgical intervention and the associated morbidity. Herein we report on a case of round ligament varicosities that presented during pregnancy and this condition was readily diagnosed via Doppler sonography

    1999-01-01

    A high-resolution magnetic spectrometer called 'Grand Raiden' is operated at the RCNP ring cyclotron facility in Osaka for nuclear physics studies at intermediate energies. This magnetic spectrometer has excellent ion-optical properties. In the design of the spectrometer, the second-order dispersion matching condition has been taken into account, and almost all the aberration terms such as (x vertical bar θ 3 ), (x vertical bar θφ 2 ), (x vertical bar θ 2 δ) and (x vertical bar θδ 2 ) in a third-order matrix calculation are optimized. A large magnetic rigidity of the spectrometer (K = 1400 MeV) gives a great advantage to measure the charge-exchange ( 3 He, t) reactions at 450 MeV. The ability of the high-resolution measurement has been demonstrated. Various coincidence measurements are performed to study the nuclear structures of highly excited states through decay properties of nuclear levels following nuclear reactions at intermediate energies

  13. Planetary Taxonomy: Label Round Bodies "Worlds"

    Science.gov (United States)

    Margot, Jean-Luc; Levison, H. F.

    2009-05-01

    The classification of planetary bodies is as important to Astronomy as taxonomy is to other sciences. The etymological, historical, and IAU definitions of planet rely on a dynamical criterion, but some authors prefer a geophysical criterion based on "roundness". Although the former criterion is superior when it comes to classifying newly discovered objects, the conflict need not exist if we agree to identify the subset of "round" planetary objects as "worlds". This addition to the taxonomy would conveniently recognize that "round" objects such as Earth, Europa, Titan, Triton, and Pluto share some common planetary-type processes regardless of their distance from the host star. Some of these worlds are planets, others are not. Defining how round is round and handling the inevitable transition objects are non-trivial tasks. Because images at sufficient resolution are not available for the overwhelming majority of newly discovered objects, the degree of roundness is not a directly observable property and is inherently problematic as a basis for classification. We can tolerate some uncertainty in establishing the "world" status of a newly discovered object, and still establish its planet or satellite status with existing dynamical criteria. Because orbital parameters are directly observable, and because mass can often be measured either from orbital perturbations or from the presence of companions, the dynamics provide a robust and practical planet classification scheme. It may also be possible to determine which bodies are dynamically dominant from observations of the population magnitude/size distribution.

  14. Anesthesiology leadership rounding: identifying opportunities for improvement.

    2012-01-01

    Rounding that includes participation of individuals with authority to implement changes has been advocated as important to the transformation of an institution into a high-quality and safe organization. We describe a Department of Anesthesiology's experience with leadership rounding. The Department Chair or other senior faculty designate, a quality coordinator, up to four residents, the ward charge nurse, and patient nurses participated in rounds at bedsides. During a 23-month period, 14 significant opportunities to improve care were identified. Nurses identified 5 of these opportunities, primary team physicians 2, the rounding team 4, and patients or their family members another 3. The anesthesiology service had sole or shared responsibility for 10 improvements. A variety of organizations track specific measures across all phases of the patient experience to gauge quality of care. Chart auditing tools for detecting threats to safety are often used. These measures and tools missed opportunities for improvement that were discovered only through rounding. We conclude that the introduction of leadership rounding by an anesthesiology service can identify opportunities for improving quality that are not captured by conventional efforts.

    2003-02-01

    The goal of nuclear forensics is to develop a preferred approach to support illicit trafficking investigations. This approach must be widely understood and accepted as credible. The principal objectives of the Round Robin Tests are to prioritize forensic techniques and methods, evaluate attribution capabilities, and examine the utility of database. The HEU (Highly Enriched Uranium) Round Robin, and previous Plutonium Round Robin, have made tremendous contributions to fulfilling these goals through a collaborative learning experience that resulted from the outstanding efforts of the nine participating internal laboratories. A prioritized list of techniques and methods has been developed based on this exercise. Current work is focused on the extent to which the techniques and methods can be generalized. The HEU Round Robin demonstrated a rather high level of capability to determine the important characteristics of the materials and processes using analytical methods. When this capability is combined with the appropriate knowledge/database, it results in a significant capability to attribute the source of the materials to a specific process or facility. A number of shortfalls were also identified in the current capabilities including procedures for non-nuclear forensics and the lack of a comprehensive network of data/knowledge bases. The results of the Round Robin will be used to develop guidelines or a ''recommended protocol'' to be made available to the interested authorities and countries to use in real cases.

    We perform global linear stability analysis on low-Re flow past a rounded cylinder. The cylinder corners are rounded with a radius R, normalized as R+ = R / D where D is the cylinder diameter, and its effect on the flow stability characteristics is investigated. We compute the critical Reynolds number (Recr) for the onset of first instability, and quantify the perturbation growth rate for the super-critical flows. It is found that the flow can be stabilized by partially rounding the cylinder. Compared with the square and circular cylinders, the partially rounded cylinder has a higher Recr , attaining a maximum at around R+ = 0 . 30 , and the perturbation growth rate of the super-critical flows is reduced for Re R+ -> 0 . 00), while only the near-wake backflow is crucial for circular-like cylinders (R+ -> 0 . 50). The stability analysis results are also verified with those of the direct simulations and very good agreement is achieved. Supported by the KAUST Office of Competitive Research Funds under Award No. URF/1/1394-01. The supercomputer Shaheen at KAUST was utilized for the simulations.

  11. Round beams generated by vertical dispersion

    International Nuclear Information System (INIS)

    Bagley, P.

    1990-01-01

    Simulations suggest that in e + e - storage rings collisions of round beams (equal emittances and equal β*) can produce very large tune shifts and luminosities. We understand how to make equal β*s, but generating equal emittances is more difficult. We describe an equal emittance scheme that uses several skew quads to couple horizontal dispersion into vertical dispersion. These skew quads also produce a coupling bump. At the interaction point and at other points outside the coupling bump, the motion is not coupled, so that the 'A' normal mode corresponds to horizontal motion and the 'B' normal mode corresponds to vertical motion. We present a round beam lattice for CESR that incorporates this scheme

    The hyper-kyphosis or "the postural round back" is one of the most common complaints in orthopedic practice. In the majority of cases, the thoracic kyphosis are painless and flexible. The vertebral bodies are normal on radiograms. This is "the kyphotic attitude" or postural round-back. A medical treatment is not the necessary rule. Life hygiene, sports and simple supervision are needed. Nevertheless, there are still pathological fixed kyphosis, induced in the majority of cases by Scheuermann's disease. The other possible etiologies (congenital, paralytic, post-traumatic, Pott's disease, postradiation, or metabolic origin) are a lot rare ones and will be excluded by clinical examination and imaging studies. The structural hyper-kyphosis require treatment. We will approach successively steps of the diagnosis and treatment of the hyper-kyphosis of the adolescent.

Touted as a "new way of looking at the elements", it is certainly thatat least at first blush. The "table" consists of four sets of two finely finished hardwood discs each with the following elemental symbols and their corresponding atomic numbers pleasingly and symmetrically wood-burned into their faces. The four sets of two discs are 1 1/2, 3, 4 1/2, and 6 in. in diameter, each disc is 3/4 in. thick, and therefore the entire "round table" stands 6 in. high and is 6 in. in diameter at its base.

    This paper presents a study of some basic blocks needed in the design of floating-point summation algorithms. In particular, in radix-2 floating-point arithmetic, we show that among the set of the algorithms with no comparisons performing only floating-point additions/subtractions, the 2Sum...... algorithm introduced by Knuth is minimal, both in terms of number of operations and depth of the dependency graph. We investigate the possible use of another algorithm, Dekker's Fast2Sum algorithm, in radix-10 arithmetic. We give methods for computing, in radix 10, the floating-point number nearest...... the average value of two floating-point numbers. We also prove that under reasonable conditions, an algorithm performing only round-to-nearest additions/subtractions cannot compute the round-to-nearest sum of at least three floating-point numbers. Starting from an algorithm due to Boldo and Melquiond, we also...

    To preserve radiology rounds in the changing health care environment, we have introduced virtual radiology rounds, an initiative enabling clinicians to remotely review imaging studies with the radiologist. We describe our initial experience with virtual radiology rounds and referring provider impressions. Virtual radiology rounds, a web-based conference, use remote sharing of radiology workstations. Participants discuss imaging studies by speakerphone. Virtual radiology rounds were piloted with the Neonatal Intensive Care Unit (NICU) and the Congenital Cardiovascular Care Unit (CCVCU). Providers completed a survey assessing the perceived impact and overall value of virtual radiology rounds on patient care using a 10-point scale. Pediatric radiologists participating in virtual radiology rounds completed a survey assessing technical, educational and clinical aspects of this methodology. Sixteen providers responded to the survey; 9 NICU and 7 CCVCU staff (physicians, nurse practitioners and fellows). Virtual radiology rounds occurred 4-5 sessions/week with an average of 6.4 studies. Clinicians rated confidence in their own image interpretation with a 7.4 average rating for NICU and 7.5 average rating for CCVCU. Clinicians unanimously rated virtual radiology rounds as adding value. NICU staff preferred virtual radiology rounds to traditional rounds and CCVCU staff supported their new participation in virtual radiology rounds. Four of the five pediatric radiologists participating in virtual radiology rounds responded to the survey reporting virtual radiology rounds to be easy to facilitate (average rating: 9.3), to moderately impact interpretation of imaging studies (average rating: 6), and to provide substantial educational value for radiologists (average rating: 8.3).

    The round table discussions of the second session of the FSC Belgium Workshop addressed the following questions: - Do local stakeholders have, internally or externally, all the expertise they need in order to address the issues raised by radioactive waste management projects? - Do institutional stakeholders have all the expertise they need to take local impacts into account? - What kinds of expert input are sought and attained by the different stakeholders? - Were any formal methods used to aid local partnerships perform technology assessments? Or other types of assessment? - How to maintain the knowledge and expertise achieved by the stakeholders? Discussion took place after the plenary presentations, at tables grouping Belgian stakeholders and FSC delegates. As in Session I, most of the round table discussion focussed specifically on the experience of the local partnerships. Many insights were shared about the nature and role of expertise in complex decision making. They are summarised below, on the basis of the feedback provided to the plenary by each round table. Some of these insights can be generalised to other contexts. All in all, a profile emerged of the local partnerships as a unique and effective tool to deal with knowledge issues in managing risk.

    After 13 years in orbit, the Cassini-Huygens Mission to Saturn ended in a science-rich blaze of glory. Cassini returned its final bits of unique science data on September 15, 2017, as it plunged into Saturn's atmosphere satisfying planetary protection requirements. Cassini's Grand Finale covered a period of roughly five months and ended with the first time exploration of the region between the rings and planet.The final close flyby of Titan in late April 2017 propelled Cassini across Saturn’s main rings and into its Grand Finale orbits; 22 orbits that repeatedly dove between Saturn’s innermost rings and upper atmosphere making Cassini the first spacecraft to explore this region. The last orbit turned the spacecraft into the first Saturn upper atmospheric probe.The Grand Finale orbits provided highest resolution observations of both the rings and Saturn, and in-situ sampling of the ring particle composition, Saturn's atmosphere, plasma, and innermost radiation belts. The gravitational field was measured to unprecedented accuracy, providing information on the interior structure of the planet, winds in the deeper atmosphere, and mass of the rings. The magnetic field provided insight into the physical nature of the magnetic dynamo and structure of the internal magnetic field. The ion and neutral mass spectrometer sampled the upper atmosphere for molecules that escape the atmosphere in addition to molecules originating from the rings. The cosmic dust analyzer directly sampled the composition from different parts of the main rings for the first time. Fields and particles instruments directly measured the plasma environment between the rings and planet.Science highlights and new mysteries gleaned to date from the Grand Finale orbits will be discussed.The research described in this paper was carried out in part at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration.

    The lecture course can be considered as introduction to the problems concerning grand unification models. The course is incomplete. Such problems as CP-violations in strong interactions and the problem of gravitational interaction inclusion in the scheme of grand unification theory are not touched upon. Models of early unification, in which strong, weak and electromagnetic interactions are compared according to the ''strength'' at energies of about 10 5 -10 6 GeV, are not discussed. Models with horizontal symmetry, considering different generations of quarks and leptons from one viewpoint, are not analyzed. Cosmological applications of supersymmetric unified theories are not considered. Certain problems of standard elementary particle theory, philosophy of the great unification, general properties of the grand unification models and the main principles of the construction of models: the SU(5) model, models on the SO(10) groups, have been considered. The problem of supersymmetric unification hierarchies, supersymmetric generalization of the minimum SU(5) model, supersymmetry violation and the problem of hierarchies, phenomenology of the o.rand unification models, cosmological application and technicolour, are discussed

    Precracking round notched bars is the first step before fracture mechanics testing. This report gives an overview of the different techniques described in the literature. Difficulties generally encountered are linked to the crack length determination and the creation of eccentric cracks. As the compliance technique is often used, a detailed study of the stress intensity factor and the compliance of the precracked bar under bending and tension is presented. Comparison with finite element calculations is made to validate the proposed analytical formulation. Finally a practical way for precracking is described

    Selmke, Markus; Selmke, Sarah

    2018-01-01

    A popular demonstration experiment in optics uses a round-bottom flask filled with water to project a circular rainbow on a screen with a hole through which the flask is illuminated. We show how the vessel's wall shifts the first- and second-order bows towards each other and consequently reduces the width of Alexander's dark band. We address the challenge this introduces in observing Alexander's dark band, and explain the importance of a sufficient distance between the flask and the screen. The wall-effect also introduces a splitting of the bows that can easily be misinterpreted.

    We report a case of endometriosis in the right inguinal region, attached to the right round ligament in a 28-year-old woman. At the age of 20, laparoscopic left ovarian cystectomy and pelvic adhesiolysis for endometriosis was carried out. She noticed a right tender groin mass 7 months previously, and the tumour size fluctuated with the menstrual cycle. A poorly circumscribed elastic hard mass, measuring 3 cm in diameter, was palpated in her right inguinal region. Magnetic resonance imaging showed a 2.5 cm x 2.5 cm mass in the right inguinal canal and a 5.4 cm x 6.8 cm mass was seen in the left ovary. The mass enlarged during menstruation. The groin mass was removed, in addition to carrying out laparoscopic ovarian cystectomy. At operation, the groin mass was found to be in continuity with the round ligament of extraperitoneal portion. Histological diagnosis of endometriosis was made in both ovarian and inguinal tumours. After surgery, the pain disappeared completely. Worth mentioning is that MRI clearly showed the change of tumour size depending on the menstrual cycle, which aided in arriving at the correct diagnosis of endometriosis in an unusual location

    This paper presents the results of a round robin exercise carried out to compare specific activity measurements performed by eight European organisations on a set of ten neutron activation detectors containing the radio-nuclides 110mAg, 60Co, 54Mn, 46Sc and 94Nb. The purpose of the exercise was to demonstrate the level of consistency between the participating organisations in blind tests of measurements relevant to reactor metrology. The samples used were selected from a stock of pre-existing irradiated material held at SCK•CEN. Taking turns over a period of approximately 9 months, the participating organisations received the samples, measured them and provided their results to an independent referee who collated and compared the data. The inter-comparison has demonstrated good agreement between the participants with standard deviations for each dosimeter varying between 1.6% and 3.1%. The paper provides results of the EWGRD Round Robin in an anonymised form together with discussion and conclusions which may be drawn from the exercise.

    The law from December 30, 1991, precisely defines 3 axes of researches for the management of high level and long-lived radioactive wastes: separation/transmutation, surface storage and underground disposal. A global evaluation report about these researches is to be supplied in 2006 by the French government to the Parliament. A first synthesis of the knowledge gained after 14 years of research has led the national commission of the public debate (CNDP) to organize a national debate about the general options of management of high-level and long-lived radioactive wastes before the 2006 date line. The debate comprises 4 public hearings (September 2005: Bar-le-Duc, Saint-Dizier, Pont-du-Gard, Cherbourg), 12 round-tables (October and November 2005: Paris, Joinville, Caen, Nancy, Marseille), a synthesis meeting (December 2005, Dunkerque) and a closing meeting (January 2006, Lyon). This document is the synthesis of the first round table debates about the information dissemination and the sharing of knowledge which took place at Caen. The main discussions of this session concerns the political decisions and the information of the public, and the transparency of this information as it should be in a western democracy. (J.S.)

    2001-11-01

    We have experimentally studied the effect of tickling a Mach 0.9 round jet with a set of microjets.Two dimensional velocity field measurements with PIV show a significant reduction in the turbulent intensities in the developing region of the jet with the activation of the microjets.Quantitatively,the axial and normal turbulence intensities are reduced by about 15respectively;even a larger effect is found on the magnitude of the correlation of axial and normal fluctuation intensities with a reduction of almost 40possible with a mass flow rate of the microjets being only about one percent of the main jet mass flow rate and hence justifying the use of the term `tickling`.The above findings are difficult to explain on the basis of stability considerations since there is very little change in the mean profile.Physically,the observed effect could be due to the alteration of the large eddy structures,which are so natural to a round jet,by the presence of the microjets.Exact nature of this interaction may be clarified with three dimensional PIV studies.It is expected that the tickling of the jet done as presently could have a favourable reflection in the aeroacoustics characteristics of the main jet.

    The present theoretical and experimental situation with grand unification is summarized. The issues of proton decay and the Weinberg angle are addressed, going through the predictions of both the standard SU(5) theory and its supersymmetric extension. The SO(10) theory, which provides a minimal one family model, is then studied. The gravitational characteristics of domain walls and strings are then discussed. It is argued that there is a need to go beyond SO(10) in order to incorporate a unified picture of families. This leads to the prediction of mirror fermions, whose physics is analyzed. 31 refs

  16. Grand Challenges for Environmental Magnetism

    Science.gov (United States)

    Verosub, K. L.

    2009-05-01

    The development of new, inexpensive, and rapid geochemical methods for determining the ages of geologic materials, their elemental composition, and their isotopic ratios over a broad array of elements puts into sharp focus the question: What information can environmental magnetic methods provide that can't be obtained using these other methods? Because iron is ubiquitous in the Earth's crust and because it exists in so many different forms, a discipline that looks in detail at iron-bearing minerals does have the potential to make significant contributions to the study of surficial processes. However, to reach that potential requires the development of new environmental magnetic methods. I would like to put forward three Grand Challenges for environmental magnetism that have the potential to move the field forward to a new level of scientific sophistication and that will allow environmental magnetists to compete successfully in a world increasingly dominated by geochemists. The first Grand Challenge is the development of new techniques that lead to the direct and unambiguous identification of the full suite of magnetic minerals. For many environmental magnetic applications, the key magnetic minerals are not just magnetite and hematite but also iron oxy-hydroxides (goethite, lepidocrocite, akaganeite, ferrihydrite), carbonates (siderite) and sulfides (pyrrhotite and greigite) as well as compounds involving iron and other transition metals (cobalt and nickel). The second Grand Challenge is the development of new analytical methods that provide specific quantitative values for the amount of each magnetic mineral present in a sample. One promising approach to this problem is the application of two- or three-component multivariate analysis to arrays of downcore environmental magnetic parameters. The third Grand Challenge is the development of new ways of determining, not just the average values, but the actual distributions of grain sizes and coercivities of each mineral

  18. Implementing iRound: A Computer-Based Auditing Tool.

    Science.gov (United States)

    Brady, Darcie

    Many hospitals use rounding or auditing as a tool to help identify gaps and needs in quality and process performance. Some hospitals are also using rounding to help improve patient experience. It is known that purposeful rounding helps improve Hospital Consumer Assessment of Healthcare Providers and Systems scores by helping manage patient expectations, provide service recovery, and recognize quality caregivers. Rounding works when a standard method is used across the facility, where data are comparable and trustworthy. This facility had a pen-and-paper process in place that made data reporting difficult, created a silo culture between departments, and most audits and rounds were completed differently on each unit. It was recognized that this facility needed to standardize the rounding and auditing process. The tool created by the Advisory Board called iRound was chosen as the tool this facility would use for patient experience rounds as well as process and quality rounding. The success of the iRound tool in this facility depended on several factors that started many months before implementation to current everyday usage.

    The Venezuelan government has disproved the long-cherished oil industry mantra that low tax rates attract private sector investors. At a time when most company managements feel they need to collect balance sheet assets at any price. Venezuela is ensuring that it remains the upmarket not the bargain basement investor target. Despite offering some of the most punitive and complicated fiscal terms worldwide, a near certainty that taxes will rise in the future and state oil company control of the join ventures' operating committees, oil investors of all sizes cannot keep away. The third marginal field reactivation round, launched late last year attracted a staggering 259 companies, both foreign and local, which prequalified to bid. (Author)

  1. On Round-off Error for Adaptive Finite Element Methods

    KAUST Repository

    Alvarez-Aramberri, J.

    2012-06-02

    Round-off error analysis has been historically studied by analyzing the condition number of the associated matrix. By controlling the size of the condition number, it is possible to guarantee a prescribed round-off error tolerance. However, the opposite is not true, since it is possible to have a system of linear equations with an arbitrarily large condition number that still delivers a small round-off error. In this paper, we perform a round-off error analysis in context of 1D and 2D hp-adaptive Finite Element simulations for the case of Poisson equation. We conclude that boundary conditions play a fundamental role on the round-off error analysis, specially for the so-called ‘radical meshes’. Moreover, we illustrate the importance of the right-hand side when analyzing the round-off error, which is independent of the condition number of the matrix.

  3. Ethics rounds: An appreciated form of ethics support.

    2016-03-01

    Ethics rounds are one way to support healthcare personnel in handling ethically difficult situations. A previous study in the present project showed that ethics rounds did not result in significant changes in perceptions of how ethical issues were handled, that is, in the ethical climate. However, there was anecdotal evidence that the ethics rounds were viewed as a positive experience and that they stimulated ethical reflection. The aim of this study was to gain a deeper understanding of how the ethics rounds were experienced and why the intervention in the form of ethics rounds did not succeed in improving the ethical climate for the staff. An exploratory and descriptive design with a qualitative approach was adopted, using individual interviews. A total of 11 healthcare personnel, working in two different psychiatry outpatient clinics and with experience of participating in ethics rounds, were interviewed. The study was based on informed consent and was approved by one of the Swedish Regional Ethical Review Boards. The participants were generally positive about the ethics rounds. They had experienced changes by participating in the ethics rounds in the form of being able to see things from different perspectives as well as by gaining insight into ethical issues. However, these changes had not affected daily work. A crucial question is whether or not increased reflection ability among the participants is a good enough outcome of ethics rounds and whether this result could have been measured in patient-related outcomes. Ethics rounds might foster cooperation among the staff and this, in turn, could influence patient care. By listening to others during ethics rounds, a person can learn to see things from a new angle. Participation in ethics rounds can also lead to better insight concerning ethical issues. © The Author(s) 2014.

  8. Use of electrical barriers to deter movement of round goby

    Science.gov (United States)

    Savino, Jacqueline F.; Jude, David J.; Kostich, Melissa J.; Coutant, Charles C.

    2001-01-01

    An electrical barrier was chosen as a possible means to deter movement of round goby Neogobius melanostomus. Feasibility studies in a 2.1-m donut-shaped tank determined the electrical parameters necessary to inhibit round goby from crossing the 1-m stretch of the benthic, electrical barrier. Increasing electrical pulse duration and voltage increased effectiveness of the barrier in deterring round goby movement through the barrier. Differences in activity of round goby during daytime and nocturnal tests did not change the effectiveness of the barrier. In field verification studies, an electrical barrier was placed between two blocking nets in the Shiawassee River, Michigan. The barrier consisted of a 6-m wide canvas on which were laid four cables carrying the electrical current. Seven experiments were conducted, wherein 25 latex paint-marked round goby were introduced upstream of the electrical barrier and recovered 24 h later upstream, on, and downstream of the barrier. During control studies, round goby moved across the barrier within 20 min from release upstream. With the barrier on and using the prescribed electrical settings shown to inhibit passage in the laboratory, the only marked round goby found below the barrier were dead. At reduced pulse durations, a few round goby (mean one/test) were found alive, but debilitated, below the barrier. The electrical barrier could be incorporated as part of a program in reducing movement of adult round goby through artificial connections between watersheds.

    As part of an NSF TUES Type 3 project entitled "Google Earth for Onsite and Distance Education (GEODE)," we are assembling a "Grand Tour" of locations on Earth and other terrestrial bodies that every geoscience student should know about and visit at least in virtual reality. Based on feedback from colleagues at previous meetings, we have identified nine Grand Tour themes: "Plates and Plumes," "Rocks and Regions," "Geology Through Time," "The Mapping Challenge*," "U.S. National Parks*," "The Magical Mystery Tour*," "Resources and Hazards," "Planets and Moons," and "Top of the Pops." Themes marked with an asterisk are most developed at this stage and will be demonstrated in real time. The Mapping Challenge invites students to trace geological contacts, measure bedding strike and dip and the plunge, trend, and facing of a fold. There is an advanced tool for modeling periclinal folds. The challenge is presented in a game-like format with an emphasis on puzzle-solving that will appeal to students regardless of gender. For the tour of U.S. national parks, we divided the most geologically important parks into four groups—Western Pacific, West Coast, Rockies, and East Coast. We are combining our own team's GigaPan imagery with imagery already available on the Internet. There is a great deal of imagery just waiting to be annotated for geological education purposes. The Magical Mystery Tour takes students to Google Streetview locations selected by instructors. Students are presented with questions or tasks and are given automatic feedback. Other themes are under development. Within each theme, we are crowd-sourcing contributions from colleagues and inviting colleagues to vote for or against proposed locations and student interactions. The GEODE team includes the authors and: Heather Almquist, Stephen Burgin, Cinzia Cervato, Gene Cooper, Paul Karabinos, Terry Pavlis, Jen Piatek, Bill Richards, Jeff Ryan, Ron Schott, Kristen St. John, and Barb Tewksbury.

    Proton hexality is a discrete symmetry that avoids the problem of too fast proton decay in the supersymmetric extension of the standard model. Unfortunately it is inconsistent with conventional grand unification. We show that proton hexality can be incorporated in the scheme of ''Local Grand Unification'' discussed in the framework of model building in (heterotic) string theory. (orig.)

    We coupled bioenergetics modeling with bottom trawl survey results to evaluate the capacity of piscivorous fish in eastern Lake Erie to exert predatory control of the invading population of round goby Neogobius melanostomus. In the offshore (>20 m deep) waters of eastern Lake Erie, burbot Lota lota is a native top predator, feeding on a suite of prey fishes. The round goby invaded eastern Lake Erie during the late 1990s, and round goby population size increased dramatically during 1999–2004. According to annual bottom trawl survey results, round goby abundance in offshore waters peaked in 2004, but then declined during 2004–2008. Coincidentally, round goby became an important component of burbot diet beginning in 2003. Using bottom trawling and gill netting, we estimated adult burbot abundance and age structure in eastern Lake Erie during 2007. Diet composition and energy density of eastern Lake Erie burbot were also determined during 2007. This information, along with estimates of burbot growth, burbot mortality, burbot water temperature regime, and energy densities of prey fish from the literature, were incorporated into a bioenergetics model application to estimate annual consumption of round goby by the adult burbot population. Results indicated that the adult burbot population in eastern Lake Erie annually consumed 1,361 metric tons of round goby. Based on the results of bottom trawling, we estimated the biomass of yearling and older round goby in offshore waters eastern Lake Erie during 2007–2008 to be 2,232 metric tons. Thus, the adult burbot population was feeding on round goby at an annual rate equal to 61% of the estimated round goby standing stock. We concluded that the burbot population had high potential to exert predatory control on round goby in offshore waters of eastern Lake Erie.

    Full Text Available In this edition of the clinical and epidemiological round, we analyzed four articles which we have considered relevant to the clinical practice. Spaite et al. studied for the first time in the medical literature the truly prognosis value of a hypotensive threshold in the reanimation of the patient with moderate to severe traumatic brain injury. Oluwalana et al. assessed the impact of oral administration of azithromycin during delivery on the risk of maternal and neonatal infections. On the other hand, Esplin et al. evaluated the accuracy of the transvaginal cervical length and serial fetal fibronectin, alone or in combination, to predict spontaneous preterm birth in nulliparous pregnant women. Finally, the FOURIER group’s study assessed the effect of the reduction on LDL cholesterol levels achieved through evolocumab administration, in patients with clinically-evident cardiovascular disease which have a statin optimized therapy, on the composite outcome of cardiovascular death, stroke, myocardial infarction and need of hospitalization due to unstable angina or coronary revascularization.

    The start of new round of WTO could be recognized as a turning point shifting from bilateral or regional trade system to multilateral trade system worldwide. The changes in international trade system are expected to have some impact on the Korean nuclear industry. The purpose of this study is to understand the impact on prepare opening the market for the plant design and engineering. This market has been protected by Agreement on Government Procurement(AGP). However, this market will be eventually influenced by GATS(General Agreement on Trade in Services) with KEPCO's on going privatization being completed. There have been no impacts on R and D fund provided by the government as yet. However, in case of Government supported R and D for commercial purpose, there are much concerns to be discussed further within new WTO agreement. It is necessary to develop a strategy for maximizing national interests and promoting R and D in the negotiation for design and construction services related with nuclear industry, and energy services. Furthermore, to effectively explore new nuclear markets in developing countries including China, market analyses for their countries are required

    Full Text Available Desmoplastic small round cell tumor (DSRCT is an extremely uncommon, highly aggressive, and malignant mesenchymal neoplasm of undetermined histogenesis. Less than 200 case reports have been documented in literature so far. Herein, we report a 26-year-old otherwise healthy female patient who presented with a 1-month history of epigastric pain. On physical examination, a palpable, slightly mobile, and tender epigastric mass was detected. All laboratory tests were normal. A chest, abdominal, and pelvic contrast-enhanced computed tomography (CT scans showed a 3.8 × 7.2 × 8.7 cm ill-defined mass, involving gastric fundus and extending into gastric cardia and lower gastroesophageal junction. It was associated with multiple enlarged gastrohepatic lymph nodes; the largest measured 1.2 cm. There was no evidence of ascites or retroperitoneal or mesenteric lymphatic metastases. Patient underwent total gastrectomy with D2 lymphadenectomy, splenectomy, and antecolic Roux-en-Y esophagojejunal anastomosis. Histopathological examination revealed coexpression of mesenchymal, epithelial, and neural markers. The characteristic chromosomal translocation (t(11; 22(p13; q12 was demonstrated on fluorescence in situ hybridization (FISH technique. Diagnosis of DSRCT of stomach was confirmed. Patient received no postoperative radiotherapy or chemotherapy. A postoperative 3-month followup failed to show any recurrence. In addition, a literature review on DSRCT is included.

    Although round pneumonia is a well-known clinical entity, there have been no large case reviews, with most knowledge based on case reports and small series from the 1960s and 1970s. To review the imaging findings of a large series of children with round pneumonia. A retrospective review of radiographic and CT findings in all children reported to have round pneumonia at a large children's hospital from 2000 to 2006 was performed. Children with underlying medical conditions were excluded. Epidemiologic characteristics, radiographic and CT findings, and follow-up imaging were reviewed. The review identified 109 children (mean age 5 years, range 4 months to 19 years). Round pneumonias tended to be solitary 98% (107/109), have well-defined borders 70% (77/109), and be posteriorly located 83% (91/109), with the following lobar distribution: left lower lobe (36), right lower lobe (33), right upper lobe (28), left upper lobe (7), right middle lobe (4), and lingula (2). Round pneumonia tended to resolve on follow-up imaging (95%, 41/43) as compared to progression to lobar pneumonia (4.6%, 2/43). Three patients (2.6%, 3/112) originally suspected to have round pneumonia were later shown to have other diagnoses: cavitary necrosis in pneumonia (two) or pleural pseudocyst (one). Round pneumonia occurs in young children (mean age 5 years), tends to be a solitary lesion, and is most commonly posteriorly located. Misdiagnosis of other pathology as round pneumonia is uncommon.

    Rounded atelectasis of the lung is well described in medical literature, but still difficult to diagnose. Since lesions give no clinical symptoms in patients, radiologists are often the first to recognize the round lesion in an X-ray picture or a CT scan. Rounded atelectasis is an atypical form of lung collapse that usually occurs adjacent to scarred pleura and can be mistaken for lung cancer. Patients with rounded atelectasis have a history of asbestos exposure or pleural effusion due to various causes. When characteristic imaging findings are present, the diagnosis is rarely dubious and no further investigation is necessary. However, differential diagnosis of rounded atelectasis poses a challenge to pulmonary specialists and radiologists

    2009-01-01

    Background: No previous study has evaluated the association between admission to ICUs during round time and patient outcome. The objective of this study was to determine the association between round-time ICU admission and patient outcome. Methods: This retrospective study included 49,844 patients admitted from October 1994 to December 2007 to four ICUs (two surgical, one medical, and one multispecialty) of an academic medical center. Of these patients, 3,580 were admitted to the ICU during round time (8:00 am to 10:59 am) and 46,264 were admitted during nonround time (from 1:00 pm to 6:00 am). The medical ICU had 24-h/7-day per week intensivist coverage during the last 2 years of the study. We compared the baseline characteristics and outcome of patients admitted to the ICU between the two groups. Data were abstracted from the acute physiology and chronic health evaluation (APACHE) III database. Results: The round-time and non-round-groups were similar in gender, ethnicity, and age. The predicted hospital mortality rate of the round time group was higher (17.4% vs 12.3% predicted, respectively; p < 0.001). The hospital length of stay was similar between the two groups. The round-time group had a higher hospital mortality rate (16.2% vs 8.8%, respectively; p < 0.001). Most of the round-time ICU admissions and deaths occurred in the medical ICU. Round-time admission was an independent risk factor for hospital death (odds ratio, 1.321; 95% CI, 1.178 to 1.481). This independent association was present for the whole study period except for the last 2 years. Conclusions: Patients admitted to the ICU during morning rounds have higher severity of illness and mortality rates. PMID:19505985

    2002-01-01

    One of the most significant challenges in large-scale climate modeling, as well as in high-performance computing in other scientific fields, is that of effectively integrating many software models from multiple contributors. A software framework facilitates the integration task, both in the development and runtime stages of the simulation. Effective software frameworks reduce the programming burden for the investigators, freeing them to focus more on the science and less on the parallel communication implementation. while maintaining high performance across numerous supercomputer and workstation architectures. This document surveys numerous software frameworks for potential use in Earth science modeling. Several frameworks are evaluated in depth, including Parallel Object-Oriented Methods and Applications (POOMA), Cactus (from (he relativistic physics community), Overture, Goddard Earth Modeling System (GEMS), the National Center for Atmospheric Research Flux Coupler, and UCLA/UCB Distributed Data Broker (DDB). Frameworks evaluated in less detail include ROOT, Parallel Application Workspace (PAWS), and Advanced Large-Scale Integrated Computational Environment (ALICE). A host of other frameworks and related tools are referenced in this context. The frameworks are evaluated individually and also compared with each other.

  10. Should This Patient Receive Prophylactic Medication to Prevent Delirium?: Grand Rounds Discussion From Beth Israel Deaconess Medical Center.

    2018-04-03

    In 2015, the American Geriatrics Society released recommendations for prevention and management of postoperative delirium, based on a systematic literature review and evaluation of nonpharmacologic and pharmacologic approaches by an expert panel. The guidelines recommend an interdisciplinary focus on nonpharmacologic measures (reorientation, medication management, early mobility, nutrition, and gastointestinal motility) for prevention and consideration of this strategy for acute management. They also recommend optimizing nonopioid medication as a means to manage pain and avoiding benzodiazepines other than to treat substance withdrawal. The authors concluded that evidence to recommend antipsychotics for prevention of delirium is insufficient but that these drugs may be considered for short-term treatment in the setting of imminent harm to the patient or caregivers or severe distress due to agitation. Patients should be given the lowest possible dose for the shortest duration when other nonpharmacologic measures have failed. In this Beyond the Guidelines, a psychiatrist and a geriatrician debate whether Mr. W, a 79-year-old man at high risk for postoperative delirium, should receive prophylactic antipsychotics with his next surgery. They review risk factors, appropriate evaluation, and potential benefits and harms of the various medications often used in this setting.

  11. Round-table discussion on food irradiation

    International Nuclear Information System (INIS)

    1973-01-01

    The possibilities of using radiation for food preservation as a way of alleviating the food deficiency problem in a large part of the world has been studied for some 20 years. Since the idea was recognized as a viable one, scientists had to develop it along three levels: firstly, the technological problems and economic viability had to be faced; at the same time tests had to be initiated to prove the wholesomeness of the irradiated foodstuffs, and then public acceptance and confidence in the end product had to be established. Work is proceeding along these three lines and in some cases, success has been won on all fronts. In others, it is continuing. As a FLASHBACK to the situation TWO YEARS AGO, we thought it interesting to reprint excerpts from a round-table discussion at which scientists from five countries sat down to discuss the pros and cons of food irradiation. ost at the gathering was Dr. Rocco Basson, Director of Chemistry at Pelindaba, South Africa, and the man responsible for directing radiation processing in that country. With him were Dr. Lapidot, Head of the Radiation and Engineering and Processing Section of the Israel Atomic Energy Commission at Soreq; Dr. Saint-Lebe of the Radioagronomy Service, French Atomic Energy Commission, at Cadarache; Dr. Ulmann, then Director of the Food Irradiation Pilot Plant at Wageningen in Holland; and Mr. Roy Hickman, leader of the International Project in the Field of Irradiation, sponsored by the FAO, IAEA and the OECD Nuclear Energy Agency, centred at Karlsruhe in Germany.

    International Nuclear Information System (INIS)

    Aebersold, M.

    2004-01-01

    The round table discussions of the first session of the Belgium Workshop addressed the following questions: - Accepting or refusing a person, an institution or a grouping as a legitimate Stakeholder who makes the decision and how? - How are the local partnerships built and organised? - How to obtain community support for the partnership's legitimate decisions/findings? - Experience teaches that no decision is reached solely by formal and legal processes. What role do informal processes play? - How can the informal procedures be accepted? Do they need to be made explicit? Discussion took place after the plenary presentations, at tables grouping Belgian stakeholders and FSC delegates. After the discussion, each table's findings were reported to the plenary. Most of the discussion concerned the local partnerships. Important findings were that the statutes for the partnerships were developed by the partnerships themselves and there were no legally binding rules handed down by the federal level. The partnerships are part of an informal process. A legally binding participation (i.e. within the EIA) will be initiated at a later stage. As the partnerships function outside of the formal legal procedure, they can function in a more flexible way. It was noted that the partnerships make recommendations, but it is not clear what the government will do with these recommendations. It was also argued that the process may cause conflicts between neighboring communities. As in other contexts visited by the FSC, the importance of the right of veto of the community was stressed, although this may cause a conflict between technical suitability and social acceptance. Access of the community to the local partnership is necessary. Finally it was accepted that time is needed to explain the recommendations to the broader community before any decisions are taken.

    2018-04-01

    Surgical Intensive Care Unit (SICU) patients "boarding" in ICUs other than the designated home unit have been shown to suffer increased rates of complications. We hypothesized that ICU rounding practices are different when SICU patients are housed in home vs. boarding ICUs. SICU rounds were observed at an academic quaternary medical center. Individual patient rounding time and order seen on rounds along with patient data and demographics were recorded. Multivariable regression analysis was used for comparison between patients. Non-boarders were older, observed on a later post ICU admission day and were more likely to be mechanically ventilated. Boarded patients were often seen at the end of rounds and for less time. Not being a boarder, age, APACHE II score on admission, vasopressor use, and positive pressure ventilation all predicted increased rounding time. Surgical ICU patients boarding in non-preferred units are often seen at the end of rounds, result in a greater reliance upon telephone communication, and receive less bedside attention from ICU provider teams.

    Conducting clinical 'rounds' is one of the most onerous and important duties that every junior doctor is expected to perform. There is evidence that newly qualified doctors are not adequately prepared by their undergraduate experiences for this task. The aim of this study was to analyse the challenges pertaining to non-technical skills that students would face during ward rounds, and to create a model that facilitates the transition from medical student to doctor. A total of 217 final-year medical students completed a simulated ward round. Free-text responses were analysed using template analysis applying an a priori template developed from the literature by the research team. This drew on the generic categories of non-technical skills suggested by Flin et al. Ninety-seven per cent of students agreed or strongly agreed that the simulated ward round improved their insight into the challenges of ward rounds and their perceived ability to work efficiently as an active member of the ward round. The responding students (206) submitted written feedback describing the learning that they planned to use: 800 learning points were recorded, and all could be categorised into one of seven non-technical skills. Conducting clinical 'rounds' is one of the most onerous and important duties that every junior doctor is expected to perform We believe that improved task efficiency and insight into the challenges of the ward round gained by medical students will lead to an enhancement in performance during clinical rounds, and will have a positive impact on patient safety. We would suggest that undergraduate medical schools consider this model in the preparation for the clinical practice element of the curriculum. © 2015 John Wiley & Sons Ltd.

    The MACRO programs which express a simple shape such as PLANE, SPHERE, CYLINDER and CONE, are used to the formation of the geometry in EGS4. Each MACRO calculates the important value for the main code to recognize the configured geometry. This calculation process may generate the calculation error due to the effect of a round-off error. SPHERE, CYLINDER and CONE MACRO include the function to avoid the effect, but PLANE MACRO dose not include. The effect of the round-off error is small usually in case of PLANE MACRO, however a slant plane may cause the expansion of the effect. Therefore, we have configured the DELPLANE program with the function to avoid the effect of the round-off error. In this study, we examine the DELPLANE program using the simply geometry with slant plane. As a result, the normal PLANE MACRO generates the round-off error, however DELPLANE program dose not generates one. (author)

    2018-02-01

    Full Text Available An increasing body of literature demonstrates that consumers associate visual information with specific gustatory elements. This phenomenon is better known as cross-modal correspondence. A specific correspondence that has received attention of late is the one between round forms and sweet taste. Research indicates that roundness (as opposed to angularity is consistently associated with an increased sweetness perception. Focusing on two different cup forms (round versus angular, two studies tested this association for a butter milk drink and a mate-based soft drink. Results, however, were not able to corroborate the frequently suggested correspondence effect, but a correspondence was found between the angular cup and a more bitter taste for the soft drink. These results are discussed in light of previous findings matching sweetness with roundness and bitterness with angularity, hopefully aiding researchers in this field in conducting future experiments.

    Teamwork between physicians and nurses has a positive association with patient satisfaction and outcomes, but perceptions of physician-nurse teamwork are often suboptimal. To improve nurse-physician teamwork in a general medicine inpatient teaching unit by increasing face-to-face communication through interprofessional bedside rounds. From July 2013 through October 2013, physicians (attendings and residents) and nurses from four general medicine teams in a single nursing unit participated in bedside rounding, which involved the inclusion of nurses in morning rounds with the medicine teams at the patients' bedside. Based on stakeholder analysis and feedback, a checklist for key patient care issues was created and utilized during bedside rounds. To assess the effect of bedside rounding on nurse-physician teamwork, a survey of selected items from the Safety Attitudes Questionnaire (SAQ) was administered to participants before and after the implementation of bedside rounds. The number of pages to the general medicine teams was also measured as a marker of physician-nurse communication. Participation rate in bedside rounds across the four medicine teams was 58%. SAQ response rates for attendings, residents, and nurses were 36/36 (100%), 73/73 (100%), and 32/73 (44%) prior to implementation of bedside rounding and 36 attendings (100%), 72 residents (100%), and 14 (19%) nurses after the implementation of bedside rounding, respectively. Prior to bedside rounding, nurses provided lower teamwork ratings (percent agree) than residents and attendings on all SAQ items; but after the intervention, the difference remained significant only on SAQ item 2 ("In this clinical area, it is not difficult to speak up if I perceive a problem with patient care", 64% for nurses vs 79% for residents vs 94% for attendings, P=0.02). Also, resident responses improved on SAQ item 1 ("Nurse input is well received in this area", 62% vs 82%, P=0.01). Increasing face-to-face communication through

    Family-centered rounds (FCR) are recommended as standard practice in the pediatric inpatient setting; however, limited data exist on best practices promoting family engagement during rounds. To identify strategies to enhance family engagement during FCR using a recognized systems engineering approach. In this qualitative study, stimulated recall interviews using video-recorded rounding sessions were conducted with participants representing the various stakeholders on rounds (15 parents/children and 22 healthcare team [HCT] members) from 4 inpatient services at a children's hospital in Wisconsin. On video review, participants were asked to provide strategies that would increase family engagement on FCR. Qualitative content analysis of interview transcripts was performed in an iterative process. We identified 21 categories of strategies corresponding to 2 themes related to the structure and process of FCR. Strategies related to the structure of FCR were associated with all five recognized work system elements: people (HCT composition), tasks (HCT roles), organization (scheduling of rounds and HCT training), environment (location of rounds and HCT positioning), and tools and technologies (computer use). Strategies related to the FCR process were associated with three rounding phases: before (HCT and family preparation), during (eg, introductions, presentation content, communication style), and after (follow-up) FCR. We identified a range of strategies to enhance family engagement during FCR. These strategies both confirm prior work on the importance of the content and style of communication on rounds and highlight other factors within the hospital work system, like scheduling and computer use, which may affect family engagement in care.

    Although round pneumonia is a well-known clinical entity, there have been no large case reviews, with most knowledge based on case reports and small series from the 1960s and 1970s. To review the imaging findings of a large series of children with round pneumonia. A retrospective review of radiographic and CT findings in all children reported to have round pneumonia at a large children's hospital from 2000 to 2006 was performed. Children with underlying medical conditions were excluded. Epidemiologic characteristics, radiographic and CT findings, and follow-up imaging were reviewed. The review identified 109 children (mean age 5 years, range 4 months to 19 years). Round pneumonias tended to be solitary 98% (107/109), have well-defined borders 70% (77/109), and be posteriorly located 83% (91/109), with the following lobar distribution: left lower lobe (36), right lower lobe (33), right upper lobe (28), left upper lobe (7), right middle lobe (4), and lingula (2). Round pneumonia tended to resolve on follow-up imaging (95%, 41/43) as compared to progression to lobar pneumonia (4.6%, 2/43). Three patients (2.6%, 3/112) originally suspected to have round pneumonia were later shown to have other diagnoses: cavitary necrosis in pneumonia (two) or pleural pseudocyst (one). Round pneumonia occurs in young children (mean age 5 years), tends to be a solitary lesion, and is most commonly posteriorly located. Misdiagnosis of other pathology as round pneumonia is uncommon.

    Discharge telephone calls made by hospital staff provide invaluable opportunities to prevent adverse events, improve quality of care, and increase patient satisfaction. Similarly, the effect of rounding on patients can improve clinical quality and improve both patient and staff satisfaction. The author discusses how the combination of implementing both nurse leader rounding and discharge telephone calls simultaneously produced powerful positive outcomes in satisfaction and patient quality of care.

  9. Il regionalismo commerciale dopo l'Uruguay Round (Commercial regionalism after the Uruguay Round

    E. GRILLI

    2013-10-01

    Full Text Available The attempts by a number of countries to partially or totally liberalise their trade on a discriminatory basis have long been documented. Despite the wide spread of the GATT in both geographical and temporal terms, regionalism has never easily co-existed with commercial multilateralism. The Uruguay Round has taken place in a period in which several key countries have radically changed trade policies. In this light, the search for a new balance between the multilateralism de jure and the regionalism de facto practiced by many members of the GATT took on importance as a test of their intentions to continue or not with the existing multilateral order or rather to modify it in a regional sense. This paper reviews the problems of coexistence between regionalism and multilateralism in the international trade order and demonstrates how few concrete conclusions can be drawn from an examination of both the theory and the empirical evidence.JEL: F13

    Evidence-based guidelines exist to reduce health care-associated infections (HAIs). Leadership rounds are one tool leaders can use to ensure compliance with guidelines, but have not been studied specifically for the reduction of HAIs. This study examines HAI leadership rounds at one facility. We explored unit-based HAI leadership rounds led by 2 hospital leaders at a large academic hospital. Leadership rounds were observed on 19 units, recorded, and coded to identify themes. Themes were linked to the Consolidated Framework for Implementation Research and used to guide interviews with frontline staff members. Staff members disclosed unit-specific problems and readily engaged in problem-solving with top hospital leaders. These themes appeared over 350 times within 22 rounds. Findings revealed that leaders used words that demonstrated fallibility and modeled curiosity, 2 factors associated with learning climate and psychologic safety. These 2 themes appeared 115 and 142 times, respectively. The flexible nature of the rounds appeared to be conducive for reflection and evaluation, which was coded 161 times. Each interaction between leaders and frontline staff can foster psychologic safety, which can lead to open problem-solving to reduce barriers to implementation. Discovering specific communication and structural factors that contribute to psychologic safety may be powerful in reducing HAIs. Published by Elsevier Inc.

    In 2009, the National Academy for Engineering issued the Grand Challenges for Engineering in the 21st Century comprised of 14 technical challenges that must be addressed to build a healthy, profitable, sustainable, and secure global community (http://www.engineeringchallenges.org). Although crucial, none of the NEA Grand Challenges adequately addressed the challenges that face the biomaterials community. In response to the NAE Grand Challenges, Monty Reichert of Duke University organized a panel entitled Grand Challenges in Biomaterials at the at the 2010 Society for Biomaterials Annual Meeting in Seattle. Six members of the National Academies—Buddy Ratner, James Anderson, Allan Hoffman, Art Coury, Cato Laurencin, and David Tirrell—were asked to propose a grand challenge to the audience that, if met, would significantly impact the future of biomaterials and medical devices. Successfully meeting these challenges will speed the 60-plus year transition from commodity, off-the-shelf biomaterials to bioengineered chemistries, and biomaterial devices that will significantly advance our ability to address patient needs and also to create new market opportunities.

    Patients' participation is essential to their well-being and sense of coherence, as well as to their understanding of and adherence to prescribed treatments. Ward rounds serve as a forum for sharing information between patient and caregiver. The purpose of the ward round is to obtain information and plan medical and nursing care through staff-patient communication. The aim and objective of this study was to investigate patients' experiences during the ward round and their ability to participate in their care. The study was qualitative and descriptive in design. Fourteen inpatients at a cardiovascular ward were interviewed. Qualitative content analysis was used for the analysis. The ethics of scientific work were adhered to. Each study participant gave his/her informed consent based on verbal and written information. The study was approved by the Research Ethics Committee at Uppsala University. The analysis revealed one theme and three subthemes related to patients' experiences of ward rounds. The main theme was handling of information from the daily ward round while waiting for private consultation. The subthemes were making the best of the short time spent on ward rounds; encountering traditional roles and taking comfort in staff competency; and being able to choose the degree to which one participates in the decision-making process. Several aspects of traditional ward round routines could be improved in regard to the two-way information exchange process between caregivers and patient. Patients' and caregivers' ability to communicate their goals and the environment in which the communication occurs are of great importance. The information provided by nurses is easier to understand than that provided by physicians. The atmosphere must be open; the patient should be treated with empathy by staff; and patients' right to participate must be acknowledged by all healthcare professionals involved. © 2013 Nordic College of Caring Science.

  13. Reviving post-take surgical ward round teaching.

    Force, Jade; Thomas, Ian; Buckley, Frances

    2014-04-01

    Learning in the clinical environment is an important feature of medical education. Ward-round teaching leads to relevant, applied and lasting learning of knowledge, skills and attitudes; however, on fast-paced ward rounds in specialties such as general surgery, the student experience is often suboptimal, and teaching can be overlooked. Clinical teaching fellows (CTFs) are postgraduate doctors ranging from foundation year-2 (FY2) level through to specialty trainees, who have elected to spend up to 2 years out of the programme to teach medical undergraduates. This article explores whether CTFs can successfully support the regular delivery of undergraduate medical teaching on the busy post-take surgical ward round (PTSWR). The CTFs at Raigmore Hospital, Inverness, planned and facilitated weekly, structured teaching sessions to accompany the PTSWR. This educational intervention was evaluated using pre- and post-intervention student questionnaires. The questionnaires focused on student enjoyment and depth of learning using Likert scales and free-text components. Students were also asked about barriers to learning on typical PTSWRs. The consultant surgeons leading on these rounds were issued separate questionnaires, to gauge their evaluation of CTF support. The main barrier to effective undergraduate ward round teaching was a lack of time on the part of clinical staff. Ward rounds accompanied by CTF support significantly increased student enjoyment (p student satisfaction, and was welcomed by clinical staff. CTF support could be widened to other busy ward rounds, e.g. acute medical takes, to enhance student learning and reduce the teaching burden on clinical faculty staff. © 2014 John Wiley & Sons Ltd.

    The effective Higgs theories at the TeV scale in supersymmetric SU(5) grand unification models are systematically derived. Restricted to extensions on 5{sub H} containing the Higgs sector we show that only two types of real (vector-like) models and one type of chiral model are found to be consistent with perturbative grand unification. While the chiral model has been excluded by the LHC data, the fate of perturbative unification will be uniquely determined by the two classes of vector-like models. (orig.)

    2016-01-01

    One way to improve confidence and encourage proliferation of additive manufacturing (AM) technologies and parts is by generating more high quality data describing the performance of AM processes and parts. Many in the AM community see round robin studies as a way to generate large data sets while distributing the cost among the participants, thereby reducing the cost to individual users. The National Institute of Standards and Technology (NIST) has conducted and participated in several of these AM round robin studies. While the results of these studies are interesting and informative, many of the lessons learned in conducting these studies concern the logistics and methods of the study and unique issues presented by AM. Existing standards for conducting interlaboratory studies of measurement methods, along with NIST’s experience, form the basis for recommended protocols for conducting AM round robin studies. The role of round robin studies in AM qualification, some of the limitations of round robin studies, and the potential benefit of less formal collaborative experiments where multiple factors, AM machine being only one, are varied simultaneously are also discussed.

    In the case of high degree targeted immunization where the number of vaccine is limited, when more than one node associated with the same degree meets the requirement of high degree centrality, how can we choose a certain number of nodes from those nodes, so that the number of immunized nodes will not exceed the limit? In this paper, we introduce a new idea derived from the selection process of second-round exam to solve this problem and then propose three improved targeted immunization strategies. In these proposed strategies, the immunized nodes are selected through two rounds of selection, where we increase the quotas of first-round selection according the evaluation criterion of degree centrality and then consider another characteristic parameter of node, such as node's clustering coefficient, betweenness and closeness, to help choose targeted nodes in the second-round selection. To validate the effectiveness of the proposed strategies, we compare them with the degree immunizations including the high degree targeted and the high degree adaptive immunizations using two metrics: the size of the largest connected component of immunized network and the number of infected nodes. Simulation results demonstrate that the proposed strategies based on two rounds of sorting are effective for heterogeneous networks and their immunization effects are better than that of the degree immunizations.

Single-subject, repeated-measures design where each subject served as his or her own control. Tertiary referral medical systems. Eighteen subjects with either conductive or mixed hearing loss who could not benefit from conventional amplification were enrolled in a clinical trial investigating vibratory stimulation of the round window. The floating mass transducer (FMT) was positioned in the round window niche. Unaided residual hearing, and aided sound field thresholds and speech perception abilities were evaluated preoperatively, and at 1, 3, 6, and 10 months post-activation of the external speech processor. Six subjects experienced complications that either required further medical management or resolved on their own. There was no difference in residual bone conduction thresholds or unaided word discrimination over time. All subjects experienced a significant improvement in aided speech perception abilities as compared to preoperative performance. Subjects with conductive and mixed hearing loss with placement of the FMT in the round window niche experienced improved sound field thresholds and speech perception, without compromising residual hearing thresholds. Vibratory stimulation of the round window via a middle ear implant may be an appropriate treatment option for patients with conductive and mixed hearing loss. Additional research is needed on the preferred placement of the FMT, improvement of functional gain, and methods to limit postoperative complications and need for revision surgery.

    Optical techniques are effective tools for diagnostic applications in medicine and are particularly attractive for the noninvasive analysis of biological tissues and fluids in vivo. Noninvasive examinations of substances via a fiber optic probe need to consider the optical properties of biological tissues obstructing the optical path. This applies to the analysis of the human perilymph, which is located behind the round window membrane. The composition of this inner ear liquid is directly correlated to inner ear hearing loss. In this work, experimental methods for studying the optical properties of the human round window membrane ex vivo are presented. For the first time, a comprehensive investigation of this tissue is performed, including optical transmission, forward scattering, and Raman scattering. The results obtained suggest the application of visible wavelengths (>400 nm) for investigating the perilymph behind the round window membrane in future.

  2. A calculational round robin in elastic-plastic fracture mechanics

    International Nuclear Information System (INIS)

    Larsson, L.H.

    Eighteen organizations participated in this round robin which treated the same three-point bend problem as an ASTM round robin four years earlier. Overall deformation, J, CTOD and crack profile were the main results required using plane strain elastic-plastic finite element analysis for a monotonically increasing load up to a maximum deformation which was far beyond the elastic regime. All elastic solutions were accurate to within a few percent. In the elastic-plastic regime, however, there was a large scatter of the results, increasing with increasing plastic deformation and roughly of the same order as in the ASTM round robin which contained ten solutions. Apparently no significant progress has taken place in the state of the art of numerical EPFM analysis in four years time. The paper discusses the reasons for this scatter and draws tentative conclusions on the most suitable numerical analysis methods in EPFM. (Auth.)

  3. How river rocks round: resolving the shape-size paradox.

    Directory of Open Access Journals (Sweden)

    Gabor Domokos

    Full Text Available River-bed sediments display two universal downstream trends: fining, in which particle size decreases; and rounding, where pebble shapes evolve toward ellipsoids. Rounding is known to result from transport-induced abrasion; however many researchers argue that the contribution of abrasion to downstream fining is negligible. This presents a paradox: downstream shape change indicates substantial abrasion, while size change apparently rules it out. Here we use laboratory experiments and numerical modeling to show quantitatively that pebble abrasion is a curvature-driven flow problem. As a consequence, abrasion occurs in two well-separated phases: first, pebble edges rapidly round without any change in axis dimensions until the shape becomes entirely convex; and second, axis dimensions are then slowly reduced while the particle remains convex. Explicit study of pebble shape evolution helps resolve the shape-size paradox by reconciling discrepancies between laboratory and field studies, and enhances our ability to decipher the transport history of a river rock.

    A round-robin test between three institutes was performed on a paraffin phase-change material (PCM) in the context of the German quality association for phase-change materials. The aim of the quality association is to define quality and test specifications for PCMs and to award certificates for successfully tested materials. To ensure the reproducibility and comparability of the measurements performed at different institutes using different measuring methods, a round-robin test was performed. The sample was unknown. The four methods used by the three participating institutes in the round-robin test were differential scanning calorimetry, Calvet calorimetry and three-layer calorimetry. Additionally, T-history measurements were made. The aim of the measurements was the determination of the enthalpy as a function of temperature. The results achieved following defined test specifications are in excellent agreement.

Dennoch erregte es Verwunderung, wenn der Schreibende Bekannten darüber berichtete, daß dies ein Forschungsgegenstand sei. Wurde von Interviews mit Grand Prix-Fans erzählt, so fielen schnell Aussagen wie: „Wie kann man sich nur für so etwas Abseitiges und Triviales wie den Grand Prix interessieren“. Dennoch bin ich der Meinung, daß Fankulturen für die entstehende Mediengesellschaft ein nicht unwichtiges Forschungsthema darstellen. Zwar geht es nicht um eine medienpädagogische Fragestellung im engeren Sinne; die Fans des Grand Prix Eurovision sind dem Jugendalter längst entwachsen. Dennoch handelt es sich bei Fangemeinschaften um Phänomene, die im Rahmen von Jugend- und Kinderkulturen von besonderer Relevanz sind. So meint Winter (1997, daß jugendliche Fanwelten eine bedeutende Rolle als Kristallisationspunkte kultureller Differenzierung spielen: ,Die Zugehörigkeit zu einer Fan weit ist Teil der jugendlichen Lebensbewältigung in der Postmoderne, denn in der Gemeinschaft der Fans können Jugendliche emotionale Allianzen eingehen, außeralltäglichen Beschäftigungen nachgehen, expressive Identitätsmuster gemeinschaftlich realisieren und sich mit ihrer Lebenssituation als Heranwachsende auseinandersetzen“ (Winter 1997, S. 51f..

    The Grand Canyon of the Colorado River, one of the world's most spectacular gorges, is a premier U.S. National Park and a World Heritage Site. The canyon supports a diverse array of distinctive plants and animals and contains cultural resources significant to the region's Native Americans. About 15 miles upstream of Grand Canyon National Park sits Glen Canyon Dam, completed in 1963, which created Lake Powell. The dam provides hydroelectric power for 200 wholesale customers in six western States, but it has also altered the Colorado River's flow, temperature, and sediment-carrying capacity. Over time this has resulted in beach erosion, invasion and expansion of nonnative species, and losses of native fish. Public concern about the effects of Glen Canyon Dam operations prompted the passage of the Grand Canyon Protection Act of 1992, which directs the Secretary of the Interior to operate the dam 'to protect, mitigate adverse impacts to, and improve values for which Grand Canyon National Park and Glen Canyon National Recreation Area were established...' This legislation also required the creation of a long-term monitoring and research program to provide information that could inform decisions related to dam operations and protection of downstream resources.

    We present images captured during Cassini's Grand Finale orbits, and their preliminary analyses. During the final 22 orbits of the mission, the spacecraft is in orbits that have 6.5 day period at an inclination of 62 degrees, apoapsis altitude of about 1,272,000 km, and periapsis altitudes of about 2,500 km. Images captured during periapsis passes show Saturn's atmosphere at unprecedented spatial resolution. We present preliminary analyses of these images, including the final images captured before the end of the mission when the spacecraft enters Saturn's atmosphere on September 15th, 2017. Prominent features captured during the final orbits include the north polar vortex and other vortices as well as very detailed views of the "popcorn clouds" that reside between the Hexagon and the north pole. In the cloud field between zonal jets, clouds either resemble linear streaks suggestive of cirrus-like clouds or round shapes suggestive of vortices or cumulus anvil. The presence of linear streaks that follow lines of constant latitudes suggests that meridional mixing is inhibited at those latitudes. The size of vortices may reflect latitudinal variation in the atmospheric deformation radius. We also compare the new images to those captured earlier in the Cassini mission to characterize the temporal evolution such as changes in the zonal jet speeds, and prevalence and colors of vortices. A particular focus of our interest is the long-term change in the color of the hexagon, the evolution of the wind speeds in the jetstream that blows eastward at the boundary of the hexagon, and the morphology of the north polar vortex. Our work has been supported by NASA PATM NNX14AK07G, NSF AAG 1212216, and NASA NESSF NNX15AQ70H.

  18. Pioneer round of translation occurs during serum starvation

    Oh, Nara; Kim, Kyoung Mi; Cho, Hana; Choe, Junho; Kim, Yoon Ki

    2007-01-01

    The pioneer round of translation plays a role in translation initiation of newly spliced and exon junction complex (EJC)-bound mRNAs. Nuclear cap-binding protein complex CBP80/20 binds to those mRNAs at the 5'-end, recruiting translation initiation complex. As a consequence of the pioneer round of translation, the bound EJCs are dissociated from mRNAs and CBP80/20 is replaced by the cytoplasmic cap-binding protein eIF4E. Steady-state translation directed by eIF4E allows for an immediate and rapid response to changes in physiological conditions. Here, we show that nonsense-mediated mRNA decay (NMD), which restricts only to the pioneer round of translation but not to steady-state translation, efficiently occurs even during serum starvation, in which steady-state translation is drastically abolished. Accordingly, CBP80 remains in the nucleus and processing bodies are unaffected in their abundance and number in serum-starved conditions. These results suggest that mRNAs enter the pioneer round of translation during serum starvation and are targeted for NMD if they contain premature termination codons

    At our institution, our microbiologist, pharmacist, and infectious disease (ID) team meet to discuss ID patients, and this meeting is referred to as microbiology rounds. We hypothesized that our microbiology rounds reduce antibiotic costs. The study involved a review of 80 patients with an ID consultation order at each of the 3 hospitals: hospital A (HA) (only HA has microbiology rounds), hospital B (HB), and hospital C (HC). Of this population, we included patients with a positive blood culture. Thirty-six patients who met the above criteria were included in the study. The average antibiotic cost/patient/day at HA, HB, and HC were $66.0, $123, and $109, respectively. Also, we found that change in antibiotics was appropriate when compared to the final microbiology results in 90%, 44%, and 40% of the time at HA, HB, and HC, respectively. Herein, we found an association between conducting microbiology rounds and reduction of antibiotic cost. Copyright © 2015 Elsevier Inc. All rights reserved.

  8. Medieval Round Churches and the Shape of the Earth.

    Haagensen, Erling; Lind, Niels C

    2015-12-01

    There is a unique cluster of four medieval round churches, linked by a simple geometry, on Bornholm Island in the Baltic Sea. Why so many and why so close together? Immediate simple answers are "Just by chance" and "For no reason." Why are the churches round? "Defense." This essay proposes another hypothesis for this unique situation: the churches are astronomical observatories, meant to solve a scientific problem (Is the Earth really spherical?) and a practical problem (How far is it to sail west to the Orient?). The capacity and desire to find answers, together with other practical needs related to astronomy, can better explain these round churches' special architecture. The geometry that connects them fits the ideal pattern with an angular accuracy of 1 minute of a degree. The round churches may be the earliest astronomical observatories in Christian Europe; other hypotheses have been shown to be untenable. Their location provides for a good method to estimate the Earth's extent in the east-west direction, seemingly the earliest such measurements.

    These lectures, mainly devoted to the cosmological implications of GUTs, also include the essential ingredients of GUTs and some of their important applications to particle physics. Section 1 contains some basic points concerning the structure of the standard strong and electroweak interactions prior to grand unification. A detailed expose of GUTs is attempted in sect. 2, including their basci principles and their consequences for particle physics. The minimal, simplest GUT, SU 5 is analysed in some detail and it will be used throughout these lectures as the GUT prototype. Finally, sect. 3 contains the most important cosmological implications of GUTs, including baryon number generation in the early Universe (in rather lengthy detail), dissipative processes in the very early Universe, grand unified monopoles, etc. (orig./HSI)

    Nagra has identified four potential sites for a repository for low- and intermediate-level waste. Exploration work is already underway at Oberbauenstock (UR) and Piz Pian Grand (GR). As part of the investigations in the Piz Pian Grand area, geological surface mapping was carried out between 1984 and 1987. Since the data obtained is still being evaluated, it would be premature to draw any interpretative conclusions at this stage. On the other hand, some of the most significant observations of this work can be summarised here. As a first step, the geological framework in which these investigations are to be seen should be defined. Observations will then be made on the rock content (lithology) and geometric structure (structural geology) of the area. (author) 6 figs

    As cost pressures mount, Grand Gulf nuclear station (GGNS) is relying increasingly on various prioritization approaches to implement, modify, eliminate, or defer regulatory requirements. Regulatory requirements can be prioritized through the use of three measures: (1) safety (or risk) significance; (2) cost; and (3) public policy (or political) significance. This paper summarizes GGNS' efforts to implement solutions to regulatory issues using these three prioritization schemes to preserve a balance between cost and safety benefit

The results were compared with a previous census made in the state and with a similar study from Australia. Meliponiculture in Rio Grande do Norte is still informal and little standardized. The activity has grown in recent years considering the mean number of nests per beekeeper. Most apiaries are formed of up to 50 colonies, usually distributed in the backyards of homes. Twelve species of stingless bees were reared in the state, and the most common was the “Jandaíra” bee (Melipona subnitida, whose honey is considered medicinal. While many beekeepers already know the importance of bees as pollinators, stingless bees are still not used for crop pollination. Compared to a recent analysis of beekeeping in Australia, meliponiculture in Brazil is more traditional, honey is the main product and the number of colonies per beekeeper is much higher. Our results highlight the need to reinforce knowledge about bees and promote specific training aimed at improving and standardizing management practices.

    An overview of the exploration and on-going activities by the petroleum industry on the Grand Banks of Newfoundland was presented. The two offshore oil developments underway are Hibernia and Terra Nova, both located in the Jeanne d'Arc Basin. Current production from Hibernia is 68,000 bopd, expected to rise to 130,000 bopd in 1999. The Terra Nova Field is still under development. Total recoverable reserves from the 17 discoveries made in the Jeanne d'Arc Basin are estimated at 1.6 billion barrels of oil and 4 trillion cubic feet of gas. Industry participants in the area include Amoco, Petro-Canada, Mobil, Chevron, Husky and Norsk Hydro. Petro-Canada believes the Grand Banks represent one of the best opportunities for oil anywhere in the world. There are currently 21 exploration licenses held on the Grand Banks. Major attractions of the area include the large reserve potential, the relatively low finding costs, the size of the pools being discovered, improvements in offshore technology that have substantially lowered development costs, and a profit-sensitive generic royalty regime that ensures reasonable rates of return for investors. figs

  2. Proton decay in grand unified theories

    International Nuclear Information System (INIS)

    Lucha, W.

    1984-01-01

    Interactions which violate the conservation of baryon and lepton number represent an intrinsic part of all grand unified theories (GUTs) of strong and electroweak interactions. These new interactions - predicted within the framework of GUTs - generate B and L violating four-fermion interactions via the exchange of superheavy particles which cannot be ascribed a well-defined baryon or lepton number. The effective coupling constant of these four-fermion interactions might be large enough to make the proton decay detectable by the present generation of experiments. In this review the basic concepts of conventional as well as supersymmetric GUTs relevant for proton decay are sketched. The baryon number violating sector of grand unified theories is discussed in more detail. Special emphasis is laid on the various selection rules arising as consequences of low-energy gauge invariance and supersymmetry for proton decay. These selection rules already determine the coarse pattern of the resulting decay modes and branching ratios without any reference to or detailed knowledge of the underlying grand unified theory. Finally the numerous theoretical predictions are summarized and confronted with experiment. (Author)

    The Rio Grande Gorge is a 115 km long river canyon located in Southern Colorado (15 km) and Northern New Mexico (100 km). The majority of the canyon is under the administration of the Bureau of Land Management {BLM), and 77 km of the canyon south of the Colorado/New Mexico border are designated Wild River under the National Wild and Scenic Rivers Act of 1968. Visits I have made to the Rio Grande Gorge over the past 15 .years disclosed some raptor utilization. As the Snake River Birds of Prey Natural Area gained publicity, its similarity to the Rio Grande Gorge became obvious, and I was intrigued by the possibility of a high raptor nesting density in the Gorge. A survey in 1979 of 20 km of the northern end of the canyon revealed a moderately high density of red-tailed hawks and prairie falcons. With the encouragement of that partial survey, and a need to assess the impact of river-running on nesting birds of prey, I made a more comprehensive survey in 1980. The results of my surveys, along with those of a 1978 helicopter survey by the BLM, are presented in this report, as well as general characterization of the area, winter use by raptors, and an assessment of factors influencing the raptor population.

J Strength Cond Res 32(2): 534-544, 2018-This study aimed to support training program development through the comparison of performance analysis of professionals mixed martial art (MMA) athletes in the bouts that were not finished by points. Using digital recordings of each bout, we analyzed 1,564 rounds (678 bouts) which were separated by ending and other rounds. Our results indicated that knockout/technical knockout is the main outcome that defines the ending round (≈60%); however, there is a higher frequency of ending by submission on the first and second rounds (>30%). Bouts ending during the first or second rounds had shorter total time and standing combat with low intensity than ending in the third round (91.5 ± 71.4, 93.4 ± 67.5, and 143.2 ± 87.4; for low intensity in the first, second, and third rounds, respectively; p ≤ 0.05), whereas standing combat time with high intensity was longer in the last round in comparison to bouts that finished in the first or second rounds (7.4 ± 9.2, 9.7 ± 18.0, and 17.7 ± 29.1 for high intensity in the first, second, and third rounds, respectively; p ≤ 0.05). The lower time dedicated to low-intensity stand-up combat actions, regardless of round, and forcefulness of the actions in groundwork in the first and second rounds seem to be elements that increase the probability of success in professional MMA bouts; these factors have essential implications related to training program design.

    MISTY1 is a 64-bit block cipher that has provable security against differential and linear cryptanalysis. MISTY1 is one of the algorithms selected in the European NESSIE project, and it has been recommended for Japanese e-Government ciphers by the CRYPTREC project. This paper reports a previously unknown higher order differential characteristic of 4-round MISTY1 with the FL functions. It also shows that a higher order differential attack that utilizes this newly discovered characteristic is successful against 6-round MISTY1 with the FL functions. This attack can recover a partial subkey with a data complexity of 253.7 and a computational complexity of 264.4, which is better than any previous cryptanalysis of MISTY1.

  7. Response of round gobies, Neogobius melanostomus, to conspecific sounds

    Isabella-Valenzi, Lisa

    A useful model group to examine reproductive plasticity in acoustic responsiveness is the family Gobiidae. Male round gobies Neogobius melanostomus emit calls and females respond to these calls with high specificity. The current study investigates differential attraction between reproductive morphologies of the goby to conspecific calls and explores the use of calls to develop a bioacoustic trap. Behavioural responsiveness to conspecific calls was tested using playback experiments in the lab and field. Females showed a strong attraction to the grunt call in both the lab and field, while nonreproductive and sneaker males preferred the drum call in the lab, but favoured the grunt call in the field. By determining the relationship between reproductive state and auditory responsiveness to conspecific calls, I am further elucidating the function of acoustic communication in the round goby and may be essential when creating control strategies to prevent the spread of the invasive species.

    Information and communication technologies (ICTs) increasingly permeate everyday life in industrialized societies. The aim of this paper is to explore ICT-related transformations of everyday practices and discuss the implications, particularly for residential electricity consumption. The present socio-technical changes are seen in a historical perspective, and it is argued that the integration of ICT into everyday practices can be seen as a new round of household electrification, comparable to earlier rounds that also led to higher electricity consumption. A case study carried out in Denmark in 2007-2008 explores the present changes in everyday life. Based on qualitative interviews, the study focuses on people's ways of integrating ICTs into their everyday practices, on any significant changes in these practices, and on the influence of the changed practices on electricity consumption. The paper concludes with a discussion on the implications for energy policy.

    The present work concerns the use of 1995 CHF table for uniformly heated round tubes, developed jointly by Canadian and Russian researchers, for the prediction of critical heat fluxes in rod bundles geometries. Comparisons between measured and calculated critical heat fluxes indicate that this table could be applied to rod bundles provided that a suitable correction factor is employed. The tolerance limits associated with the departure from nucleate boiling ratio (DNBR) are evaluated by using statistical analysis. (author)

    1996-05-01

    The measure of the fracture toughness of a circumferentially-cracked round bar is generally performed through approximate formulae. Comparison of existing formulae to finite element results does not always show good agreement. Therefore an eta factor is introduced in order to improve the existing analytical formula. The axisymmetrical geometry is generally considered to be a high constrained geometry. Finite element calculations are performed to verify and quantify the constraint relative to the three point bending configuration (precracked Charpy)

    Bilò, Vittorio; Fanelli, Angelo; Flammini, Michele; Moscardelli, Luca

    We investigate the approximation ratio of the solutions achieved after a one-round walk in linear congestion games. We consider the social functions {Stextsc{um}}, defined as the sum of the players’ costs, and {Mtextsc{ax}}, defined as the maximum cost per player, as a measure of the quality of a given solution. For the social function {Stextsc{um}} and one-round walks starting from the empty strategy profile, we close the gap between the upper bound of 2+sqrt{5}≈ 4.24 given in [8] and the lower bound of 4 derived in [4] by providing a matching lower bound whose construction and analysis require non-trivial arguments. For the social function {Mtextsc{ax}}, for which, to the best of our knowledge, no results were known prior to this work, we show an approximation ratio of Θ(sqrt[4]{n^3}) (resp. Θ(nsqrt{n})), where n is the number of players, for one-round walks starting from the empty (resp. an arbitrary) strategy profile.

    2005-01-01

    Full Text Available Abstract Background Desmoplastic small round cell tumor (DSRCT is a rare and highly aggressive neoplasm. The cytological diagnosis of these tumors can be difficult because they show morphological features quite similar to other small round blue cells tumors. We described four cases of DSRCT with cytological sampling: one obtained by fine needle aspiration biopsy (FNAB and three from serous effusions. The corresponding immunocytochemical panel was also reviewed. Methods Papanicolaou stained samples from FNAB and effusions were morphologically described. Immunoreaction with WT1 antibody was performed in all cytological samples. An immunohistochemical panel including the following antibodies was performed in the corresponding biopsies: 34BE12, AE1/AE3, Chromogranin A, CK20, CK7, CK8, Desmin, EMA, NSE, Vimentin and WT1. Results The smears showed high cellularity with minor size alteration. Nuclei were round to oval, some of them with inconspicuous nucleoli. Tumor cells are clustered, showing rosette-like feature. Tumor cells in effusions and FNA were positive to WT1 in 3 of 4 cytology specimens (2 out 3 effusions and one FNA. Immunohistochemical reactions for vimentin, NSE, AE1/AE3 and WT1 were positive in all cases in tissue sections. Conclusion The use of an adjunct immunocytochemical panel coupled with the cytomorphological characteristics allows the diagnosis of DSRCT in cytological specimens.

    Demands for revision of existing medical law were described together with an introduction of TV fluoroscopic unit. Round mask, which does not always press out the bottom face of used x-ray beam from the effective primary fluorescent face of photomultiplier inspite of shifting of a spot in time of TV fluoroscopy, was manufactured for trial, and it was furnished with already established fluoroscopic stand. It is used in daily examination without any trouble. Round mask was divided into two parts, and opened upward and downward quickly by lod motor in time of photographing. Multiple iris was operated in order to fit to film size, and round mask was closed at the same time of the finishment of photographing and fluoroscopy was performed again. Item 3 of Para 2 of Art 30 of the existing medical low states that it is good not to press out, the distance between x-ray focus and fluorescent screen, and used x-ray beam from fluorescent screen. However, a regulation, which states that x-ray beam should not be pressed out from effective primary fluorescent face in x-ray fluoroscopy using photomultiplier, must be added. Improvement of the existing unit is expected, and decrease of unnecessary exposure even in small amount is proposed. (Tsunoda, M.)

    2002-12-01

    Full Text Available This paper focuses on the impact of the Uruguay Round (UR implementation on world agriculture using a multi-regional general equilibrium model and the mapping function of the Geographic Information System (GIS. The results of this study show that the Uruguay Round has had a negative impact on world agriculture in the light of total food production and food distribution. For commodities such as grains, while grain production rises in exporting countries, the effect is not sufficient to cover the fall in production in importing countries. In particular, the impact is serious on food security in importing countries of agricultural products. The negative impact is almost concentrated in importing countries, particularly Japan, the European Union (EU and South Korea. As is clearly visible on the maps produced by the GIS function, the real state of world agriculture as well as the results evaluated by this Computable General Equilibrium (CGE model has changed negatively in major importing countries and particularly the Least Developed Countries (LDCs, Sub-Saharan Africa following the Uruguay Round.

  9. A calculational round robin in elastic-plastic fracture mechanics

    1983-01-01

    Eighteen organisations participated in this elastic-plastic fracture mechanics (EPFM) numerical analysis round robin which treated the same three-point bend problem as a similar round robin conducted by ASTM four years earlier. The work involved the calculation of overall deformation, J, CTOD and crack profile using plane strain elastic-plastic finite element analysis for a monotonically increasing load up to a maximum deformation which was far beyond the elastic regime. It was found that all of the elastic solutions were accurate to within a few per cent. In the elastic-plastic regime, however, there was a large scatter of the results, increasing with increasing plastic deformation and roughly of the same order as in the ASTM round robin which contained ten solutions. No significant progress has taken place in the state of the art of numerical EPFM analysis over the four-year interval. The reasons for this scatter and tentative conclusions on the most suitable numerical analysis methods in EPFM are discussed. (author)

    Introduction Park amenities promote visitation and physical activity during summer. Physical activity declines during winter. Identifying park amenities that promote visitation during winter would increase year-round activity. The purpose of this study was to determine how park visitation, amenity choice, and physical activity intensity change across seasons. Methods Physical activity intensity of children and adults was assessed at 16 parks in Grand Forks, North Dakota, during summer and fall of 2012, and winter and spring of 2013. Results Park visitation was highest in spring and lowest in winter. Amenity use varied by season. Parks with water splash pads were visited more during summer, and playgrounds and open spaces were visited more during spring. Ice rinks were visited most in winter. Physical activity intensity was lowest in summer and highest in winter for each age group. The activity intensity observed for all young age groups ranged from 2.7 to 2.9 metabolic equivalents in summer and greater than 3 metabolic equivalents in all other seasons. Adults’ mean activity intensity was greater than 3 metabolic equivalents in winter. Conclusion Information on park visitation, amenity use, and activity intensity across seasons is valuable; it can be used when designing or redesigning parks in order to promote year-round physical activity. Redesigning parks in cold climates to include ice rinks, sledding hills, cross-country skiing, and indoor areas for physical activity would increase winter visitation and allow the park to serve as a year-round resource for physical activity.

  12. LEP constraints on grand unified theories

    International Nuclear Information System (INIS)

    Sarkar, Utpal

    1993-01-01

    Recent developments on grand unified theories (GUTs) in the context of the LEP measurements of the coupling constants are reviewed. The three coupling constants at the electroweak scale have been measured at LEP quite precisely. One can allow these couplings to evolve with energy following the renormalization group equations for the various groups and find out whether all the coupling constants meet at any energy. It was pointed out that the minimal SU(5) grand unified theory fails to satisfy this test. However, various extensions of the theory are still allowed. These extensions include (i) supersymmetric SU(5) GUT, with some arbitrariness in the susy breaking scale arising from the threshold corrections, (ii) non-susy SU(5) GUTs with additional fermions as well as Higgs multiplets, which has masses of the order of TeV, and (iii) non-renormalizable effect of gravity with a fine tuned relation among the coupling constants at the unification energy. The LEP results also constrain GUTs with an intermediate symmetry breaking scale. By adjusting the intermediate symmetry breaking scale, one usually can have unification, but these theories get constrained. For example, the left-right symmetric theories coming from GUTs can be broken only at energies higher than about ∼10 10 GeV. This implies that if right handed gauge bosons are found at energies lower than this scale, then that will rule out the possibility of grand unification. Another recent interesting development on the subject, namely, low energy unification, is discussed in this context. All the coupling constants are unified at energies of the order of ∼10 8 GeV when they are embedded in an SU(15)GUT, with some particular symmetry breaking pattern. But even in this case the results of the intermediate symmetry breaking scale remain unchanged. (author). 16 refs., 3 figs

    Study Design: Case control study. Place and Duration of Study: Gynecology and Obstetric Unit-I of the Jinnah Post Graduate and Medical Centre Karachi, from February 2009 to January 2010. Patients and Methods: One hundred (100) patients of grand multipara (GMP), (parity = 5) and 100 patients of multipara (MP) (parity 2-4) were included in the study. Pregnant women with known medical conditions including essential hypertension, diabetes mellitus, epilepsy, primigravidas, women with previous caesarean section and twin pregnancies were excluded. Patients were admitted through antenatal clinic and emergency. A detailed history was taken and a physical examination was done with special emphasis on obstetrical examination. Investigations like blood CP, Urine D/R, blood grouping and sonogram were done. During labour, mother and neonates were managed according to ward protocols. Maternal and fetal outcomes were compared among GMPs and MPs. Results: A high frequency of anaemia (81% vs 20%), pregnancy induced hypertension (45%, vs. 26%) and gestational diabetes (9%, vs1%) were seen in GMP as compared to MP group. Frequency of malpresentations (26% vs 15%), postpartum hemorrhage (15%, vs 10%) and intrauterine deaths (26%, vs 13%) were higher in GMP group along with a high caesarean delivery rate (GMP 21%, MP 14%). A higher maternal mortality (GMP 4%, MP 1%) and low APGAR score (GMP 12%, MP 4%) were observed among babies born to grand multipara group. Conclusion: Grand multiparity is associated with adverse outcome for both mother and fetus. Effort should be directed to reduce high parity in the community through effective family planning initiatives. Specialized antenatal and obstetrical care facilities should be available. (author)

    Physicians need easy access to evidence for clinical decisions while they care for patients but, to our knowledge, no investigators have assessed use of evidence during rounds with house staff. To determine if it was feasible to find and apply evidence during clinical rounds, using an "evidence cart" that contains multiple sources of evidence and the means for projecting and printing them. Descriptive feasibility study of use of evidence during 1 month (April 1997) and anonymous questionnaire (May 1997). General medicine inpatient service. Medical students, house staff, fellows, and attending consultant. Evidence cart that included 2 secondary sources developed by the department (critically appraised topics [CATs] and Redbook), Best Evidence, JAMA Rational Clinical Examination series, the Cochrane Library, MEDLINE, a physical examination textbook, a radiology anatomy textbook, and a Simulscope, which allows several people to listen simultaneously to the same signs on physical examination. Number of times sources were used, type of sources searched and success of searches, time needed to search, and whether the search affected patient care. The evidence cart was used 98 times, but could not be taken on bedside rounds because of its bulk; hard copies of several sources were taken instead. When the evidence cart was used during team rounds and student rounds, some sources could be accessed quickly enough (10.2-25.4 seconds) to be practical on our service. Of 98 searches, 79 (81%) sought evidence that could affect diagnostic and/or treatment decisions. Seventy-one (90%) of 79 searches regarding patient management were successful, and when assessed from the perspective of the most junior team members responsible for each patient's evaluation and management, 37 (52%) of the 71 successful searches confirmed their current or tentative diagnostic or treatment plans, 18 (25%) led to a new diagnostic skill, an additional test, or a new management decision, and 16 (23

  15. Studies of turbulent round jets through experimentation, simulation, and modeling

    Science.gov (United States)

    Keedy, Ryan

    This thesis studies the physics of the turbulent round jet. In particular, it focuses on three different problems that have the turbulent round jet as their base flow. The first part of this thesis examines a compressible turbulent round jet at its sonic condition. We investigate the shearing effect such a jet has when impinging on a solid surface that is perpendicular to the flow direction. We report on experiments to evaluate the jet's ability to remove different types of explosive particles from a glass surface. Theoretical analysis revealed trends and enabled modeling to improve the predictability of particle removal for various jet conditions. The second part of thesis aims at developing a non-intrusive measurement technique for free-shear turbulent flows in nature. Most turbulent jet investigations in the literature, both in the laboratory and in the field, required specialized intrusive instrumentation and/or complex optical setups. There are many situations in naturally-occurring flows where the environment may prove too hostile or remote for existing instrumentation. We have developed a methodology for analyzing video of the exterior of a naturally-occurring flow and calculating the flow velocity. We found that the presence of viscosity gradients affects the velocity analysis. While these effects produce consistent, predictable changes, we became interested in the mechanism by which the viscosity gradients affect the mixing and development of the turbulent round jet. We conducted a stability analysis of the axisymmetric jet when a viscosity gradient is present. Finally, the third problem addressed in this thesis is the growth of liquid droplets by condensation in a turbulent round jet. A vapor-saturated turbulent jet issues into a cold, dry environment. The resulting mixing produces highly inhomogeneous regions of supersaturation, where droplets grow and evaporate. Non-linear interactions between the droplet growth rate and the supersaturation field make

    This work presents some concepts in group theory and Lie algebras and, at same time, shows a method to study and work with semisimple Lie groups, based on Dynkin diagrams. The aproach taken is not completely formal, but it presents the main points of the elaboration of the method, so its mathematical basis is designed with the purpose of making the reading not so cumbersome to those who are interested only in a general picture of the method and its usefulness. At the end it is shown a brief review of gauge theories and two grand-unification models based on SO(13) and E 7 gauge groups. (author) [pt

    We develop a formalism for general relativistic, grand canonical ensembles in space-times with timelike Killing fields. Using that, we derive ideal gas laws, and show how they depend on the geometry of the particular space-times. A systematic method for calculating Newtonian limits is given for a class of these space-times, which is illustrated for Kerr space-time. In addition, we prove uniqueness of the infinite volume Gibbs measure, and absence of phase transitions for a class of interaction potentials in anti-de Sitter space.

    GRANDE is an imaging, water Cerenkov detector, which combines in one facility an extensive air shower array and a high-energy neutrino detector. We proposed that the detector be constructed in phases, beginning with an active detector area of 31,000 m 2 (GRANDE-I) 2 and expanding to a final size of 100,000--150,00 m 2 . Some of the characteristics of GRANDE-I are discussed in this paper

  4. SO(10) supersymmetric grand unified theories

    Science.gov (United States)

    Dermisek, Radovan

    The origin of the fermion mass hierarchy is one of the most challenging problems in elementary particle physics. In the standard model fermion masses and mixing angles are free parameters. Supersymmetric grand unified theories provide a beautiful framework for physics beyond the standard model. In addition to gauge coupling unification these theories provide relations between quark and lepton masses within families, and with additional family symmetry the hierarchy between families can be generated. We present a predictive SO(10) supersymmetric grand unified model with D 3 x U(1) family symmetry. The hierarchy in fermion masses is generated by the family symmetry breaking D 3 x U(1) → ZN → nothing. This model fits the low energy data in the charged fermion sector quite well. We discuss the prediction of this model for the proton lifetime in light of recent SuperKamiokande results and present a clear picture of the allowed spectra of supersymmetric particles. Finally, the detailed discussion of the Yukawa coupling unification of the third generation particles is provided. We find a narrow region is consistent with t, b, tau Yukawa unification for mu > 0 (suggested by b → sgamma and the anomalous magnetic moment of the muon) with A0 ˜ -1.9m16, m10 ˜ 1.4m16, m16 ≳ 1200 GeV and mu, M1/2 ˜ 100--500 GeV. Demanding Yukawa unification thus makes definite predictions for Higgs and sparticle masses.

    Full Text Available Através da análise da opinião dos editoriais dos quatro principais periódicos diários da grande imprensa, isto é, o Jornal do Brasil, O Globo, a Folha de S. Paulo e O Estado de S. Paulo - aqui considerados "aparelhos privados de hegemonia" -, este artigo procura desvendar os posicionamentos adotados perante a ordem social na Constituinte de 1987/1988, que também contribuem para compreender a reação à Consolidação das Leis do Trabalho. Observa-se, além do mais, as estratégias utilizadas para sua consecução. Conclui-se que, por mecanismos diversos, a grande imprensa contribuiu decisivamente para a introdução da agenda ideológica neoliberal no país, pois atuou de forma a "divulgar e vulgarizar" as idéias pertinentes a este ideário e de forma militantemente conservadora e patronal.

    2010-01-01

    Objective: To observe the change of ultrastructure and pathology of desmoplastic small round cell tumor (DSRCT) and recognize the characteristics of DSRCT and improve the standard of diagnosis. Methods: One case of primary DSRCT in right leg was observed by light microscope, immunohistochemical method and electron microscope and analyzed with review of the literatures. Results: The size of tumor was 3.2 cm x 2.4 cm x 1.3 cm with gray-yellow on cross-section. Foci of hemorrhage and necrosis were noted. Under light microscope, the tumor was composed of sharply demarcated nests of small rounded or oval cells. The cellular aggregates were surrounded and separated by abundant fibrous connective tissue. The tumor cells were uniform in size and shape, and showed small to moderate amounts of pale cytoplasm with indistinct cell borders. The nuclei were round to oval, with clumped chromatin and marked hyperchromasia. Some cells had one or two indistinct nucleoli. Numerous mitotic figures and areas of necrosis were dentified. The immunohistochemical results showed that the tumor cells were strongly positive for CK, EMA and NSE. There was focal positive staining for desmin with a perinuclear dot-like pattern. However, the tumor cells were negative for CgA, Myogenin, Syn, LCA, SMA, S-100, NF, GFAP, HMB45, HHF-35, CD3, CD10, Actin, CD99, and CD20. Under electron microscope, the tumor cells showed paranuclear cytoplasmic intermediate filaments arranging in globular or whorl array. Conclusion: DSRCT occurs both in the abdomen and at other sites. The patients with DSRCT range widely in age. DSRCT has distinctive histopathologic and ultrastructural features. This tumor shows immunohistochemical feature of epithelial, mesenchymal as well as neural multidirectional differentiation. RT-PCR may be served as an important diagnostic adjunct for DSRAT. The prognosis of the patients with DSRCT is very poor. (authors)

  12. Impacts of the Doha Round framework agreements on dairy policies.

    Science.gov (United States)

    Suzuki, N; Kaiser, H M

    2005-05-01

    Dairy is highly regulated in many countries for several reasons. Perishability, seasonal imbalances, and inelastic supply and demand for milk can cause inherent market instability. Milk buyers typically have had more market power than dairy farmers. Comparative production advantages in some countries have led to regulations and policies to protect local dairy farmers by maintaining domestic prices higher than world prices. A worldwide consensus on reduction of border measures for protecting dairy products is unlikely, and dairy will probably be an exception in ongoing World Trade Organization (WTO) negotiations. Under the Doha Round framework agreements, countries may name some products such as dairy as "sensitive," thereby excluding them from further reforms. However, new Doha Round framework agreements depart from the current WTO rule and call for product-specific spending caps. Such caps will greatly affect the dairy sector because dairy accounts for much of the aggregate measure of support (AMS) in several countries, including the United States and Canada. Also, the amounts of dairy AMS in several countries may be recalculated relative to an international reference price. In addition, all export subsidies are targeted for elimination in the Doha Round, including export credit programs and state trading enterprises, which will limit options for disposing of surplus dairy products in foreign markets. Currently, with higher domestic prices, measures for cutting or disposing of surpluses have been used in many countries. Supply control, which is not regulated by WTO rules, remains as an option. Although explicit export subsidies are restricted by WTO rules, many countries use esoteric measures to promote dairy exports. If countries agree to eliminate "consumer financed" export subsidies using a theoretical definition and measurements proposed herein as Export Subsidy Equivalents (ESE), dairy exports in many countries may be affected. Although domestic supports and

    Fourteen ago the Wingspread Project helped establish geoscience education research (GER) as an important research field and highlighted major research questions for GER at the time. More recently, the growth and interest in GER is evident from the increase in geoscience education research articles, the establishment of the NAGT GER Division, the creation of the GER Toolbox, an increase in GER graduate programs, and the growth of tenure-eligible GER faculty positions. As an emerging STEM education research field, the GER community is examining the current state of their research and considering the best course forward so that it can have the greatest collective impact on advancing teaching and learning in the geosciences. As part of an NSF-funded effort to meet this need, 45 researchers drafted priority research questions, or "Grand Challenges", that span 10 geoscience education research themes. These include research on: students' conceptual understanding of the solid and the fluid Earth, K-12 teacher preparation, teaching about Earth in the context of societal problems, access and success of underrepresented groups in the geosciences, spatial and temporal reasoning, quantitative reasoning and use of models, instructional strategies to improve geoscience learning, students' self-regulated learning, and faculty professional development and institutional change. For each theme, several Grand Challenges have been proposed; these have undergone one round of peer-review and are now ready for the AGU community to critically examine the proposed Grand Challenges and make suggestions on strategies for addressing them: http://nagt.org/nagt/geoedresearch/grand_challenges/feedback.html. We seek perspectives from geoscience education researchers, scholars, and reflective educators. It is our vision that the final outcomes of this community-grounded process will be a published guiding framework to (1) focus future GER on questions of high interest to the geoscience education

    Full Text Available The milky white latex of plant Calotropis procera produces inflammation of the skin and mucous membranes on accidental exposure. It produces edema on local administration due to the release of histamine and prostaglandins and is associated with hyperalgesia. In the present study we have evaluated the antiedematous and analgesic activity of antiinflammatory drugs against inflammatory response induced by dried latex (DL of C procera in rat paw edema model. An aqueous extract of DL of C procera was injected into the subplantar surface of the rat paw and the paw volume was measured by a plethysmometer at 0, 1, 2, 6, 12, and 24 hours. Concomitantly the hyperalgesic response was also evaluated by motility test, stair climbing ability test, dorsal flexion pain test, compression test, and observing the grooming behavior. The inhibitory effect of diclofenac and rofecoxib on edema formation and hyperalgesic response was compared with cyproheptadine (CPH. DL-induced edema formation was maximum at 2 hours that was associated with decreased pain threshold, functional impairment, and grooming. Treatment with antiinflammatory drugs and CPH significantly attenuated the edematous response and grooming, increased the pain threshold, and improved functional parameters. Both antiinflammatory and antiserotonergic drugs significantly inhibited the hyperalgesia associated with DL-induced paw edema. Rofecoxib was found to be superior than diclofenac and was as effective as CPH in ameliorating the hyperalgesia. However, it was found to be less effective than CPH in attenuating edema formation.

    The effect of C Cl 4 and n-butyl acrylate as a sensitizer for radiation vulcanization of 60% DRC natural rubber latex with gamma rays, was studied relating tensile strength of vulcanized latex. The vulcanization dose is 200 kGy for natural rubber latex and it decreases to 40 kGy and to 9 kGy in the presence of C Cl 4 / potassium laureate and n-butyl acrylate / t-butyl hydroperoxide, respectively. The H 2 O 2 as a co-sensitizer does not change the efficiency of the combination of these sensitizers. The IV spectra show the formation of C=O after the irradiation as consequence of oxidation reactions. (author)

    Fully vulcanized polybutadiene rubber particles (FVBR) were prepared by polybutadiene latex (PBL) vulcanization induced by 60 Co γ-rays irradiation, and the effect of absorbed dose on crosslinking behavior was studied. Mean diameter, diameter distribution and morphology of the particles in the PBL irradiated at different doses as well as in the FVBR were characterized by laser particle analyzer and AFM. The crosslinking effect on the mechanical properties of the films, by casting from PBL at different doses correspondingly, was evaluated by mechanical and dynamic mechanical analysis (DMA) respectively. The results showed that the diameter and swelling property decreased with absorbed dose, while crosslink density and gel fraction increased. Moreover, the decrease of the tensile strength and elongation at break, the increase of the hardness in shore A and young's modulus (E), and the increase of storage modulus (E') and narrowing of loss tangent peak (Tan 8) were all accounted for the increment of crosslinking. The Charlesby-Pinner equation fits well with the PBL vulcanization in the range of absorbed doses from 0 to 200kGy. (authors)

Interruptions during rounds were reported to be common (i.e., ≥ 1 interruption for ≥ 50% of patients in 46% of ICUs. Four themes were identified from qualitative analysis of participant responses to open-ended survey questions and interviews: multidisciplinarity, patient and family involvement, factors influencing productivity, and teaching and learning.There is considerable variation in current rounding practices in Canadian medical/surgical ICUs. Opportunities exist to improve ICU rounds including ensuring the engagement of essential participants, clearly defining participant roles, establishing a standardized approach to the rounding process, minimizing interruptions, modifying the role of teaching, utilizing a structured rounding tool, and developing a metric for measuring rounding quality.

  3. La masa de los grandes impactores

    Science.gov (United States)

    Parisi, M. G.; Brunini, A.

    Los planetas han sido formados fundamentalmente acretando masa a través de colisiones con planetesimales sólidos. La masa más grande de la distribución de planetesimales y las masas máxima y mínima de los impactores, han sido calculadas usando los valores actuales del período y de la inclinación de los planetas (Lissauer & Safronov 1991; Parisi & Brunini 1996). Recientes investigaciones han mostrado, que las órbitas de los planetas gigantes no han sufrido variaciones con el tiempo, siendo su movimiento regular durante su evolución a partir de la finalización de la etapa de acreción (Laskar 1990, 1994). Por lo tanto, la eccentricidad actual de los planetas gigantes se puede utilizar para imponer una cota máxima a las masas y velocidades orbitales de los grandes impactores. Mediante un simple modelo dinámico, y considerando lo arriba mencionado, obtenemos la cota superior para la masa del planetesimal más grande que impactó a cada planeta gigante al final de su etapa de acreción. El resultado más importante de este trabajo es la estimación de la masa máxima permitida para impactar a Júpiter, la cúal es ~ 1.136 × 10 -1, siendo en el caso de Neptuno ~ 3.99 × 10 -2 (expresada en unidades de la masa final de cada planeta). Además, fue posible obtener la velocidad orbital máxima permitida para los impactores como una función de su masa, para cada planeta. Las cotas obtenidas para la masa y velocidad de los impactores de Saturno y Urano (en unidades de la masa y velocidad final de cada planeta respectivamente) son casi las mismas que las obtenidas para Júpiter debido a que estos tres planetas poseen similar eccentricidad actual. Nuestros resultados están en buen acuerdo con los obtenidos por Lissauer & Safronov (1991). Estas cotas podrían ser utilizadas para obtener la distribución de planetesimales en el Sistema Solar primitivo.

    The paper designs a roundness measurement model with multi-systematic error, which takes eccentricity, probe offset, radius of tip head of probe, and tilt error into account for roundness measurement of cylindrical components. The effects of the systematic errors and radius of components are analysed in the roundness measurement. The proposed method is built on the instrument with a high precision rotating spindle. The effectiveness of the proposed method is verified by experiment with the standard cylindrical component, which is measured on a roundness measuring machine. Compared to the traditional limacon measurement model, the accuracy of roundness measurement can be increased by about 2.2 μm using the proposed roundness measurement model for the object with a large radius of around 37 mm. The proposed method can improve the accuracy of roundness measurement and can be used for error separation, calibration, and comparison, especially for cylindrical components with a large radius.

  6. Transient Three-Dimensional Side Load Analysis of Out-of-Round Film Cooled Nozzles

    2010-01-01

    The objective of this study is to investigate the effect of nozzle out-of-roundness on the transient startup side loads at a high altitude, with an anchored computational methodology. The out-of-roundness could be the result of asymmetric loads induced by hardware attached to the nozzle, asymmetric internal stresses induced by previous tests, and deformation, such as creep, from previous tests. The rocket engine studied encompasses a regeneratively cooled thrust chamber and a film cooled nozzle extension with film coolant distributed from a turbine exhaust manifold. The computational methodology is based on an unstructured-grid, pressure-based computational fluid dynamics formulation, and a transient inlet history based on an engine system simulation. Transient startup computations were performed with the out-of-roundness achieved by four different degrees of ovalization: one perfectly round, one slightly out-of-round, one more out-of-round, and one significantly out-of-round. The results show that the separation-line-jump is the peak side load physics for the round, slightly our-of-round, and more out-of-round cases, and the peak side load increases as the degree of out-of-roundness increases. For the significantly out-of-round nozzle, however, the peak side load reduces to comparable to that of the round nozzle and the separation line jump is not the peak side load physics. The counter-intuitive result of the significantly out-of-round case is found to be related to a side force reduction mechanism that splits the effect of the separation-line-jump into two parts, not only in the circumferential direction and most importantly in time.

    The low energy effective action of string theory depends strongly on the process of compactification and the localization of fields in extra dimensions. Explicit string constructions towards the minimal supersymmetric standard model (MSSM) reveal interesting results leading to the concept of local grand unification. Properties of the MSSM indicate that we might live at a special location close to an orbifold fixed point rather than a generic point in Calabi-Yau moduli space. We observe an enhancement of (discrete) symmetries that have various implications for the properties of the MSSM such as proton stability as well as solutions to the flavor problem, the m-problem and the strong CP-problem.

    A Unified Grand Tour of Theoretical Physics invites its readers to a guided exploration of the theoretical ideas that shape our contemporary understanding of the physical world at the fundamental level. Its central themes, comprising space-time geometry and the general relativistic account of gravity, quantum field theory and the gauge theories of fundamental forces, and statistical mechanics and the theory of phase transitions, are developed in explicit mathematical detail, with an emphasis on conceptual understanding. Straightforward treatments of the standard models of particle physics and cosmology are supplemented with introductory accounts of more speculative theories, including supersymmetry and string theory. This third edition of the Tour includes a new chapter on quantum gravity, focusing on the approach known as Loop Quantum Gravity, while new sections provide extended discussions of topics that have become prominent in recent years, such as the Higgs boson, massive neutrinos, cosmological perturba...

    Wali, K.C.

    1989-01-01

    This chapter presents an introduction into Grand Unified Theories. After a discussion of the general features to be expected in any such theory, and of the motivations for them, a detailed presentation of SU(5) theory is given. The group structures, particle multiplets, gauge and Higgs bosons are explained. The two stages of spontaneous symmetry breaking via the Higgs model, are calculated individually and in combination. Fermion mass matrices and relations between quark and lepton masses are derived. predictions of SU(5) theory, calculated using renormalization group methods, are derived. The chapter ends with discussions that bring together particle physics and cosmology, including the baryon asymmetry problem, phase transitions in the very early universe, and singularities like domain walls, vortex lines and monopoles.

    Lazarides, G.; Shafi, Q.

    1983-01-01

    By examining the behavior of supersymmetric grand unified theories (GUT's) in the very early universe we find two classes of realistic models. In one of them supersymmetry is broken at or near superheavy GUT scale. The cosmological implications of such models are expected to be similar to those of nonsupersymmetric GUT's. In the second class of models, the superheavy GUT scale is related to the supersymmetry-breaking scale in the manner of Witten. Two types of cosmological scenarios appear possible in this case, either with or without an intermediate (new) inflationary phase. They can be experimentally distinguished, since the former predicts an absence and the latter an observable number density of superheavy monopoles. A mechanism for generating baryon asymmetry in such models is pointed out

  12. Preface to a GUT (Grand Unified Theory)

    International Nuclear Information System (INIS)

    Honig, W.

    1982-01-01

    A Grand Unified Theory (GUT) is proposed exhibiting relativistic invariance and based on a physical model for vacuum space consisting of the superposition of oppositely charged continuous fluids. Models for the photon, electron, neutrino, proton, etc., consist of separate unique variations in the relative densities of the fluids and their flow patterns. This GUT is also based on the use of transfinite axiomatic number forms and on a concept of metrical relativity which hopefully reconciles the many logical dichotomies in and between Special Relativity and Quantum Mechanics. These ideas result in a number of experimental proposals and predicted results which appear to be underivable from present paradigms, first among which is a physical model for the hidden variable of Quantum Mechanics. It is on these features that attention should rest. (Auth.)

  13. Higgsless grand unified theory breaking and trinification

    International Nuclear Information System (INIS)

    Carone, Christopher D.; Conroy, Justin M.

    2004-01-01

    Boundary conditions on an extra dimensional interval can be chosen to break bulk gauge symmetries and to reduce the rank of the gauge group. We consider this mechanism in models with gauge trinification. We determine the boundary conditions necessary to break the trinified gauge group directly down to that of the standard model. Working in an effective theory for the gauge-symmetry-breaking parameters on a boundary, we examine the limit in which the grand-unified theory-breaking-sector is Higgsless and show how one may obtain the low-energy particle content of the minimal supersymmetric standard model. We find that gauge unification is preserved in this scenario, and that the differential gauge coupling running is logarithmic above the scale of compactification. We compare the phenomenology of our model to that of four dimensional 'trinified' theories

    The grand unified theories (GUT) of the simple Lie groups including extra Z bosons are discussed. Under authors's hypothesis there are only SU 5+m SO 6+4n and E 6 groups. The general discussion of SU 5+m is given, then the SU 6 and SU 7 are considered. In SU 6 the 15+6 * +6 * fermion representations are used, which are not same as others in fermion content, Yukawa coupling and broken scales. A conception of clans of particles, which are not families, is suggested. These clans consist of extra Z bosons and the corresponding fermions of the scale. The all of fermions in the clans are down quarks except for the standard model which consists of Z bosons and 15 fermions, therefore, the spectrum of the hadrons which are composed of these down quarks are different from hadrons at present

    Volpini, Giovanni; Statera, Marco

    2016-01-01

    A novel type of superferric magnets suitable to arbitrary multipole orders was proposed by I. F. Malyshev and later by V. Kashikhin. This new topology, which we refer to as round coil superferric magnets (RCSM), allows a great simplification of the superconducting part, which in the simplest case may be composed by a single round coil, which has intrinsically a rather large bending radius allowing the use of strain-sensitive superconductors. INFN is designing and building a prototype of a multipolar corrector magnet based on this geometry and using MgB2 tapes. In this paper, we investigate a number of issues pertaining to the electromagnetic characteristics of RCSM. The RCSM magnetic has inherently even harmonics, in addition to usual odd ones and a solenoidal component. Either (but not both) disappears when integrated using a one-coil or a two-coil specular design. We investigate the effect of saturation on the multipolar components and on the load line, since in RCSM, saturation plays a role that differs bo...

  18. Japanese round robin analysis for probabilistic fracture mechanics

    International Nuclear Information System (INIS)

    1991-01-01

    Recently attention is focused on the probabilistic fracture mechanics, a branch of fracture mechanics with probability theory for a rational mean to assess the strength of components and structures. In particular, the probabilistic fracture mechanics is recognized as the powerful means for quantitative investigation of significance of factors and rational evaluation of life on problems involving a number of uncertainties, such as degradation of material strength, accuracy and frequency of inspection. Comparison with reference experiments are generally employed to assure the analytical accuracy. However, accuracy and reliability of analytical methods in the probabilistic fracture mechanics are hardly verified by experiments. Therefore, it is strongly needed to verify the probabilistic fracture mechanics through the round robin analysis. This paper describes results from the round robin analysis of flat plate with semi-elliptic cracks on the surface, conducted by the PFM Working Group of LE Subcommittee of the Japan Welding Society under the contract of the Japan Atomic Energy Research Institute and participated by Tokyo University, Yokohama National University, the Power Reactor and Nuclear Fuel Corporation, Tokyo Electric Power Co.

    Two international round-robin studies were conducted on transport properties measurements of bulk thermoelectric materials. The study discovered current measurement problems. In order to get ZT of a material four separate transport measurements must be taken. The round-robin study showed that among the four properties Seebeck coefficient is the one can be measured consistently. Electrical resistivity has +4-9% scatter. Thermal diffusivity has similar +5-10% scatter. The reliability of the above three properties can be improved by standardizing test procedures and enforcing system calibrations. The worst problem was found in specific heat measurements using DSC. The probability of making measurement error is great due to the fact three separate runs must be taken to determine Cp and the baseline shift is always an issue for commercial DSC. It is suggest the Dulong Petit limit be always used as a guide line for Cp. Procedures have been developed to eliminate operator and system errors. The IEA-AMT annex is developing standard procedures for transport properties testing.

    Interdisciplinary rounds (IDR) provide a means to assemble hospital team members and improve collaboration. Little is known about teamwork during IDR. To evaluate and characterize teamwork during IDR. Cross-sectional observational study. Six medical units which had implemented structured interdisciplinary rounds (SIDR). We adapted the Observational Teamwork Assessment for Surgery (OTAS) tool, a behaviorally anchored rating scale shown to be reliable and valid in surgical settings. OTAS provides scores ranging from 0 to 6 (0 = problematic behavior; 6 = exemplary behavior) across 5 domains (communication, coordination, cooperation/backup behavior, leadership, and monitoring/situational awareness) and for prespecified subteams. Two researchers conducted direct observations using the adapted OTAS tool. We conducted 7-8 independent observations for each unit (total = 44) and 20 joint observations. Inter-rater reliability was excellent at the unit level (Spearman's rho = 0.75), and good across domains (rho = 0.53-0.68) and subteams (rho = 0.53-0.76) with the exception of the physician subteam, for which it was poor (rho = 0.35). Though teamwork scores were generally high, we found differences across units, with a median (interquartile range [IQR]) 4.5 (3.9-4.9) for the lowest and 5.4 (5.3-5.5) for the highest performing unit (P teamwork during SIDR across units, domains, and most subteams. Variation in performance suggests a need to improve consistency of teamwork and emphasizes the importance of leadership. Copyright © 2012 Society of Hospital Medicine.

    Research highlights: → We have presented a novel approach to detect dynamic eccentricity in round rotor synchronous motors. → We have introduced an efficient index based on processing torque using time series data mining method. → The stator current spectrum of the motor under different levels of fault and load are computed. → Winding function method has been employed to model healthy and faulty synchronous motors. -- Abstract: In this paper, a novel approach is presented to detect dynamic eccentricity in round rotor synchronous motors. For this, an efficient index is introduced based on processing developed torque using time series data mining (TSDM) method. This index can be utilized to diagnose eccentricity fault and its degree. The capability of this index to predict dynamic eccentricity is illustrated by investigation of load variation impacts on the nominated index. Stator current spectrum of the faulty synchronous motor under different loads and dynamic eccentricity degrees are computed. Effects of the dynamic eccentricity and load variation simultaneously are scrutinized on the magnitude of 17th and 19th harmonic components as traditional indices for eccentricity fault diagnosis in synchronous motors. Necessity signals and parameters for processing and feature extraction are evaluated by winding function method which is employed to model healthy and faulty synchronous motors.

  3. Facial sculpting: Comprehensive approach for aesthetic correction of round face

    2012-01-01

    Full Text Available Context: Standards for an aesthetic face are dynamic. The current trend is towards a leaner looking face with preservation of the inverted triangle of youth. Procedures that have been reported to be employed for correction of a chubby face include buccal fat pad excision, facial liposuction and injection lipolysis. In addition to giving the face an aesthetic triangular cut, chin and malar augmentation may be performed. The rounded appearance at the angles may further be reduced by injection of Botulinum toxin into the masseter. Materials and Methods: Forty patients who presented to us for correction of chubby (round faces were analysed and treated by facial sculpting surgery, which included at least two of the procedures in combination. The procedures included facial liposuction, buccal fat pad excision, chin augmentation, malar augmentation and injection lipolysis. All cases were followed-up for a minimum of 6 months after surgery. Results: Aesthetic expectations of the patients were met in 39 cases, one patient complained of facial asymmetry following facial liposuction and was subjected to a touch-up injection lipolysis. Conclusions: A combination of procedures is necessary to give the face an attractive contour. All the individual procedures have stood the test of time and are safe, proven and are put in mainstream. However, a thorough analysis of the face preoperatively and then subjecting the patient to a combination of these procedures in a single surgical sitting has yielded good results as seen in this study.

    Part of the pressure tubes surveillance program of CANDU type reactors is to determine the fracture toughness using a special fracture specimen and test procedure. Atomic Energy of Canada Limited decided to hold a Round Robin Test International and 9 laboratories participated worldwide in which several pressure tube materials were selected: Zircaloy-2, Zr-2.5%Nb cold worked and Zr-2.5%Nb heat treated. The small specimens used held back the thickness and curvature of the tube. J-R curves at room temperature were obtained and the crack extension values were determined by electrical potential drop techniques. These values were compared with results generated from other laboratories and a bid scatter was founded. It could be due to slight variations in the test method or inhomogeneity of the materials and a statistical study must be done to see if there is any pattern. The next step for the Round Robin Test would be to make some modifications in the test method in order to reduce the scatter. (Author)

    Constructed during the period 1960-1965, the Grand Rapids Generating Station is a 472 MW hydroelectric station located approximately 400 kilometres northwest of Winnipeg, Manitoba, on the Saskatchewan River. An intake structure, four penstocks, a four-unit plus house unit powerhouse, wing walls, extensive dyke structures and a four-bay spillway are the components of the generating station. A little over ten years ago, the Manitoba Hydro Dam Safety Program was initiated. The program included a detailed dam safety review of the Grand rapids Generating Station. A potential deficiency in the freeboard allowance for several of the earthen dykes was revealed by the review process. The dam safety guidelines sponsored by the Canadian Dam Association were not met. The occurrence of a 1:1000 year wind event from the critical direction when the reservoir was at or near its full supply level was compounded by the analysis. The establishment of a wind and wave monitoring program was included in the deficiency studies commissioned. The objective was to confirm the empirical estimates concerning wave height, the development and usage of a two dimensional numerical wave model, and additional freeboard analyses to refine estimates of the recurrence interval of the current level of protection. A statistical Monte Carlo analysis was performed in the case of the estimates of the recurrence interval to determine the joint probabilities of seasonal variations in wind direction, wind speed, and reservoir level. The estimate of the actual risk of overtopping was therefore refined, and the details pertaining to the methodology and the conclusions of the analysis are all included in the paper. 15 refs., 4 tabs., 9 figs.

    El objetivo de este trabajo es el desarrollo de modelos y algoritmos numericos que simulen el comportamiento del material bajo estas condiciones en el contexto de programas de elementos finitos, dando como resultado predicciones mas precisas de los procesos de conformado y deformacion plastica en general. Para lograr este objetivo se han desarrollado diversas tareas destinadas a mejorar las predicciones en tres aspectos fundamentales. El primer aspecto consiste en la mejora de la descripcion del endurecimiento cinematico anisotropo en pequenas deformaciones, lo cual se ha realizado a traves de modelos y algoritmos implicitos de superficies multiples. Ha sido estudiada la consistencia de este tipo de modelos tanto si estan basados en una regla implicita similar a la de Mroz o en la regla de Prager. Ademas se han simulado los ensayos de Lamba y Sidebottom, obteniendo, en contra de la creencia general, muy buenas predicciones con la regla de Prager. Dichos modelos podrian ser extendidos de forma relativamente facil para considerar grandes deformaciones a traves de procedimientos en deformaciones logaritmicas, similares a los desarrollados en esta tesis y detallados a continuacion. El segundo aspecto consiste en la descripcion de la anisotropia elastoplastica inicial. Esto se ha conseguido mediante el desarrollo de modelos y algoritmos para plasticidad anisotropa en grandes deformaciones, bien ignorando la posible anisotropia elastica, bien considerandola simultaneamente con la anisotropia plastica. Para ello ha sido necesario desarrollar primero un nuevo algoritmo de elastoplasticidad anisotropa en pequenas deformaciones consistentemente linealizado y sin despreciar ningun termino, de tal forma que se conserve la convergencia cuadratica de los metodos de Newton. Este algoritmo en pequenas deformaciones ha servido para realizar la correccion plastica de dos algoritmos en grandes deformaciones. El primero de estos algoritmos es una variacion del clasico algoritmo de

    The incorporation of family-centered rounds has become standard in PICUs across the United States. We compared rounding times in our institution, with and without family members present, to determine the effect on total rounding time and work flow. This observational study of a convenience sample was conducted over a 17-month period (May 2014-October 2015), accounting for typical seasonal variation in the PICU. The individual patient rounding times for 2657 encounters were recorded. The presence of family members, intubation status, physician assistant participation, interruptions during rounds, attending physician's full- or part-time status, and patient census were documented. The effect of family presence on per-patient rounding time was analyzed, while controlling for influential variables. Family members were present during 1743 of 2657 (66%) rounding encounters. The average per-patient rounding time with and without family members present was 8.6 minutes and 7.3 minutes, respectively, a difference of 1.3 minutes per patient. In statistical models that accounted for other influential variables, the presence of family members was associated with a highly significant (20.4%, P family members increases per-patient rounding times in the PICU. Family presence on rounds may have benefits that outweigh the additional time required to complete each patient interaction. Copyright © 2017 by the American Academy of Pediatrics.

    2007-01-01

    Little is known about the ecology of round goby (Neogobius melanostomus), an invasive benthic fish, in the profundal zone of the Great Lakes. In April 2002–2005 we caught increasing numbers of round gobies with a bottom trawl in the 45–150 m depth range of southwestern Lake Ontario. In 2005, we examined gut contents of 30 round gobies from each of three depths, 55, 95, and 130 m, and qualitatively compared gut contents with density of benthic invertebrates determined by Ponar grabs. Round goby guts contained mostly Dreissena spp. and opposum shrimp, Mysis relicta (Mysis); the frequency of occurrence of dreissenids in guts decreased with depth, whereas the frequency of occurrence of Mysis in guts increased with depth. Abundance of these invertebrates in the environment followed the same pattern, although dreissenids of optimum edible size (3–12 mm) were still abundant (1,373/m2) at 130 m, where round gobies primarily consumed Mysis, suggesting that round gobies may switch from dreissenids to more profitable prey when it is available. Other food items were ostracods and fish, with ostracods generally eaten by smaller round gobies and fish eaten by larger round gobies. Occurrence and increasing abundance of round gobies in the profundal zone and predation on Mysis by round goby could have far-reaching consequences for the Lake Ontario fish community.

  15. Round Ligament of Uterus Leiomyoma: An Unusual Cause of Dyspareunia

    2015-01-01

    Full Text Available Round ligament of uterus leiomyoma is a rare, benign tumor of the vulva. Its incidence is not known exactly, and the mean age ranges from 13 to 70. Although clinical properties of benign and malignant diseases in the vulvar area are frequently similar, early diagnosis and treatment are essential. Local excision is recommended as definitive therapy. We present an 28-year-old female without any birth with a mass in anterior vaginal wall diagnosed as vulvar leiomyoma. In conclusion, a brief review of relevant literature emphasizes that leiomyomas are quite rare outside of the uterus but they might occur in any tissue or organ containing smooth muscle, spontaneously or parasitically after the spreading effect of an accident or surgical trauma. Clinicians should be alert especially for the diagnosis in a tissue with smooth muscle content.

Numerical simulations of a multilateral market-access reform scenario show that such cuts would lead to across-the-board decreases in intra-EU trade...... external trade surpluses in many EU agricultural products. Further, the resulting adjustments in member states’ production and net trade positions are not equal: the new member states would generally lose part of their export shares in the EU market to external competitors, as highlighted in the cases......The July package of the Doha Round of trade negotiations stipulates that a tiered-formula approach should be used to significantly reduce market access barriers across countries, implying that the EU would have to make larger cuts to its high external tariffs, in comparison with many other WTO...

    Desmoplastic small round cell tumor (DSRCT) is a rare malignant neoplasm typically involving the abdominal cavity of a young male. Extra-abdominal occurrence of this tumor is very rare. We report a 10-year-old girl with primary DSRCT arising within the left femur. The patient presented with knee pain, and radiological findings were strongly suggestive of osteogenic sarcoma. In addition to the typical microscopic appearance and immunophenotype, RT-PCR demonstrated the chimeric transcript of EWS-WT1, which is diagnostic of DSRCT. Pulmonary metastases were present at initial staging studies, but no abdominal or pelvic lesion was present. Despite chemotherapy and complete tumor excision, the patient developed progressive lung and bone metastases and died 3 years after initial presentation. This is the second reported case of primary DSRCT of bone with genetic confirmation. (orig.)

  18. NUFACT11 round table discussion questions and answers

    2013-01-01

    This presents the response to questions formulated by a round table discussion panel to the NUFACT11 participants. The main points made were as follows. Neutrino mass is physics beyond the Standard Model, it presents a very deep puzzle to solve, with the answers to several fundamental questions as potential reward. Precision measurement of oscillation parameters is one essential way to access information needed to solve this puzzle and there is a relatively clear (but not easy) way forward. Large θ(13) makes the appearance signals larger, but does not allow to relax the requirements on high beam intensity and large detector masses, it creates a difficult challenge on systematic errors, which will require dedicated ancillary experiments. Of particular interest is a low intensity muon storage ring for required cross-section measurements. There exist already extended bottom-up international collaboration in both physics and R&D experiments. All three main regions have plans for upgraded super-beams and asso...

    The round window membrane (RWM)-intentioned approach is superior to the traditional bony cochleostomy (BC) approach in obtaining electrode placement within the scala tympani (ST). Cochlear implant outcome is influenced by several factors, including optimal placement and retention of the electrode array within the ST. The present study aimed to assess whether the RWM route is superior to a traditional BC for placement and retention of the electrode array in the ST. This was a prospective consecutive non-randomized comparison study. All patients were implanted with the Advanced Bionics 1J electrode array. The RWM approach (n = 32) was compared with a traditional BC group (n = 33). The outcome measure was the electrode position as judged within the scalar chambers at four points along the basal turn using postoperative computed tomography (CT). When the mean position scores were compared, the RWM-intentioned group had significantly more electrodes directed towards the ST compartment than the BC group (p scala vestibuli.

  20. Method for wrapping a wire round a nuclear fuel rod

    1974-01-01

    Object: To provide a method for winding a wire round a nuclear fuel rod with accurate pitches without imparting any local strain or torsion to the wire. Structure: A wire is fixed on one end of the fuel rod, and the other end of the wire is secured to a universal joint leaving a winding allowance to the fuel rod. The wire is linearly stretched by a predetermined tension through the universal joint so as to provide an angle of development theta corresponding to the desired winding pitch, and then, the fuel rod may be rotated so that the end of the wire on the side of the universal joint is moved towards the fuel rod so as to render the angle of development theta constant in proportion to said rotation of the fuel rod.

    There have been many presentations of thermographic residential building analyses at the past ThermosInse conferences. A number of these papers have dealt with evaluation of insulation voids and more recently a few have described air leakage detection 2,3 during the colder winter months. This paper will focus on the thermographic application in the House Doctor instrumented energy analysis approach as developed by Princeton University. The central theme will be the application to a year-round research or commercial activity. Some of the conditions that could create thermographic problems, as well as techniques that may be used to lessen these difficulties, thereby extending the thermographic "season" is discussed. Our experiences in summer thermography with and without the use of a building pressurization system is also covered.

This finding is relevant when one takes into account the importance of interdisciplinary teamwork; a review conducted by Epstein concluded that effective interprofessional teamwork both maximizes patient safety and increases job satisfaction and efficiency.2 We, as medical students, believe that inadequate emphasis is placed on interprofessional collaboration at the prequalification phase, and therefore, we suggest that implementing IBR at the university level could represent a method to improve teamwork between the nurses and doctors of the future.  View the original paper by Henkin et al.

    A three-round algorithm is presented that guarantees agreement in a system of K greater than or equal to 3F+1 nodes provided each faulty node induces no more than F faults and each good node experiences no more than F faults, where, F is the maximum number of simultaneous faults in the network. The algorithm is based on the Oral Message algorithm of Lamport, Shostak, and Pease and is scalable with respect to the number of nodes in the system and applies equally to traditional node-fault model as well as the link-fault model. We also present a mechanical verification of the algorithm focusing on verifying the correctness of a bounded model of the algorithm as well as confirming claims of determinism.

    Full Text Available Grand fir (Abies grandis (Douglas ex D. Don Lindley is widely distributed in the moist forests of the Inland Northwest. It has high potential productivity, its growth being nearly equal to western white pine, the most productive species in the region. There are large standing volumes of grand fir in the region. Nutritionally, the species has higher foliage cation concentrations than associated conifers, especially potassium (K and calcium (Ca. In contrast, it has lower nitrogen (N foliage concentrations, which creates favorable nutrient balance on N-limited sites. Despite concentration differences, grand fir stores proportionally more nutrients per tree than associated species because of greater crown biomass. Although few fertilization trials have examined grand fir specifically, its response is inferred from its occurrence in many monitored mixed conifer stands. Fertilization trials including grand fir either as a major or minor component show that it has a strong diameter and height growth response ranging from 15% to 50% depending in part on site moisture availability and soil geology. Grand fir tends to have a longer response duration than other inland conifers. When executed concurrently with thinning, fertilization often increases the total response. Late rotation application of N provides solid investment returns in carefully selected stands. Although there are still challenges with the post-fertilization effects on tree mortality, grand fir will continue to be an important species with good economic values and beneficial responses to fertilization and nutrient management.

    To describe the implementation and evaluation of a case-based microbiology curriculum during daily microbiology rounds. Vignettes consist of short cases with images and questions that facilitate discussion among microbiologists, pathologists, infectious disease physicians, and trainees (residents and fellows). We performed a survey to assess the value of these vignettes to trainees. Motivation to come to rounds on time increased from 60% to 100%. Trainees attending rounds after implementation of the vignettes perceived the value of microbiology rounds to be significantly higher compared with those who attended rounds before implementation (P = .04). Pathology residents found that vignettes were helpful for retaining knowledge (8.3 of 10 points). The vignettes have enhanced the value of microbiology rounds by serving as a formalized curriculum exposing trainees from multiple specialties to various microbiology topics. Emphasis on interdisciplinary interactions between clinical and laboratory personnel was highlighted with this case-based curriculum.

    Almost eight years after the launch of the Doha Round, the WTO negotiations remain mired in a swamp of detail, with many participants unwilling or unable to make the hard decisions which would bring the Round to a conclusion. Meanwhile, the world has changed dramatically with the onset of a global economic crisis of proportions seldom, if ever, seen before. This has radically changed the context within which the Round is placed and may lead to fundamental rethinking of its future. This paper ...

  9. Reprogramming of round spermatids by the germinal vesicle cytoplasm in mice.

    Directory of Open Access Journals (Sweden)

    Peng-Cheng Kong

    Full Text Available The birthrate following round spermatid injection (ROSI remains low in current and evidence suggests that factors in the germinal vesicle (GV cytoplasm and certain substances in the GV such as the nucleolus might be responsible for genomic reprogramming and embryonic development. However, little is known whether the reprogramming factors in GV oocyte cytoplasm and/or nucleolus in GV are beneficial to the reprogramming of round spermatids and development of ROSI embryos. Here, round spermatids were treated with GV cytolysates and injected this round spermatid alone or co-injected with GV oocyte nucleolus into mature metaphase II oocytes. Subsequent embryonic development was assessed morphologically and by Oct4 expression in blastocysts. There was no significant difference between experimental groups at the zygote to four-cell development stages. Blastocysts derived from oocytes which were injected with cytolysate treated-round spermatid alone or co-injected with nucleoli injection yielded 63.6% and 70.3% high quality embryos, respectively; comparable to blastocysts derived by intracytoplasmic sperm injection (ICSI, but higher than these oocytes which were co-injected with lysis buffer-treated round spermatids and nucleoli or injected with the lysis buffer-treated round spermatids alone. Furthermore, the proportion of live offspring resulting from oocytes which were co-injected with cytolysate treated-round spermatids and nucleoli or injected with cytolysate treated-round spermatids alone was higher than those were injected with lysis buffer treated-round spermaids, but comparable with the ICSI group. Our results demonstrate that factors from the GV cytoplasm improve round spermatid reprogramming, and while injection of the extra nucleolus does not obviously improve reprogramming its potential contribution, although which cannot be definitively excluded. Thus, some reprogramming factors are evidently present in GV oocyte cytoplasm and could

  11. Proton decay: Numerical simulations confront grand unification

    1985-01-01

    The Grand Unified Theories of the electromagnetic, weak and strong interactions constitute a far reaching attempt to synthesize our knowledge of theoretical particle physics into a consistent and compelling whole. Unfortunately, many quantitative predictions of such unified theories are sensitive to the analytically intractible effects of the strong subnuclear theory (Quantum Chromodynamics or QCD). The consequence is that even ambitious experimental programs exploring weak and super-weak interaction effects often fail to give definitive theoretical tests. This paper describes large-scale calculations on a supercomputer which can help to overcome this gap between theoretical predictions and experimental results. Our focus here is on proton decay, though the methods described are useful for many weak processes. The basic algorithms for the numerical simulation of QCD are well known. We will discuss the advantages and challenges of applying these methods to weak transitions. The algorithms require a very large data base with regular data flow and are natural candidates for vectorization. Also, 32-bit floating point arithmetic is adequate. Thus they are most naturally approached using a supercomputer alone or in combination with a dedicated special purpose processor. (orig.)

    While working as the marketing intern for Kennedy Space Center's (KSC) Center Planning and Development Directorate (CPD), I was given the opportunity not only to learn new skills and expand my work experience under the powerful influence of NASA, but I also was given the opportunity to prove that I am an individual capable of contributing to the KSC team. My main responsibility while working in CPD was to organize and run a booth that represented the entire directorate at the Grand Opening of the Shuttle Atlantis exhibit during the weekend of June 28-30. This event was important for CPD because as a Directorate that markets KSC's facilities, technical capabilities and technologies to potential partners, it is important to attend all events and use them to gain an understanding of our audience. Although we catered mostly to the general public during this event, it was still important to reach out to the larger space enthusiast community and let them know about KSC's future plans to become a multi-user spaceport and that teclmology is still being developed.

  13. The grand descent has begun for CMS

    CERN Multimedia

    2006-01-01

    Until recently, the CMS experimental cavern looked relatively empty; its detector was assembled entirely at ground level, to be lowered underground in 15 sections. On 2 November, the first hadronic forward calorimeter led the way with a grand descent. The first section of the CMS detector (centre of photo) arriving from the vertical shaft, viewed from the cavern floor. There is something unusual about the construction of the CMS detector. Instead of being built in the experimental cavern, like all the other detectors in the LHC experiments, it was constructed at ground level. This was to allow for easy access during the assembly of the detector and to minimise the size of the excavated cavern. The slightly nerve-wracking task of lowering it safely into the cavern in separate sections came after the complete detector was successfully tested with a magnetic field at ground level. In the early morning of 2 November, the first section of the CMS detector began its eagerly awaited descent into the underground ca...

    2009-06-01

    We consider the possibility that the unification of the electroweak interactions and the strong force arises from string theory, at energies significantly lower than the string scale. As a tool, an effective grand unified field theory in six dimensions is derived from an anisotropic orbifold compactification of the heterotic string. It is explicitly shown that all anomalies cancel in the model, though anomalous Abelian gauge symmetries are present locally at the boundary singularities. In the supersymmetric vacuum additional interactions arise from higher-dimensional operators. We develop methods that relate the couplings of the effective theory to the location of the vacuum, and find that unbroken discrete symmetries play an important role for the phenomenology of orbifold models. An efficient algorithm for the calculation of the superpotential to arbitrary order is developed, based on symmetry arguments. We furthermore present a correspondence between bulk fields of the orbifold model in six dimensions, and the moduli fields that arise from compactifying four internal dimensions on a manifold with non-trivial gauge background.

  15. Gauge hierarchy problem in grand unified theories

    International Nuclear Information System (INIS)

    Alhendi, H.A.A.

    1982-01-01

    In grand unification schemes, several mass scales are to be introduced, with some of them much larger than all the others, to cope with experimental observations, in which elementary particles of higher masses require higher energy to observe them than elementary particles of lower masses. There have been controversial arguments in the literature on such hierarchical scale structure, when radiative corrections are taken into account. It has been asserted that the gauge hierarchy depends on the choice of the subtraction point (in the classical field space), of the four-point function at zero external momentum. It also has been asserted that the gauge hierarchy problem whenever it is possible to be maintained in one sector of particles, it also is possible to be maintained in the other sectors. These two problems have been studied in a prototype model, namely an 0(3)-model with two triplets of real scalar Higgs fields. Our analysis shows that, within ordinary perturbation theory, none of these two problems is quite correct

  16. Grand unification in the projective plane

    International Nuclear Information System (INIS)

    Hebecker, A.

    2004-01-01

    A 6-dimensional grand unified theory with the compact space having the topology of a real projective plane, i.e., a 2-sphere with opposite points identified, is considered. The space is locally flat except for two conical singularities where the curvature is concentrated. One supersymmetry is preserved in the effective 4d theory. The unified gauge symmetry, for example SU(5), is broken only by the non-trivial global topology. In contrast to the Hosotani mechanism, no adjoint Wilson-line modulus associated with this breaking appears. Since, locally, SU(5) remains a good symmetry everywhere, no UV-sensitive threshold corrections arise and SU(5)-violating local operators are forbidden. Doublet-triplet splitting can be addressed in the context of a 6d N=2 super Yang-Mills theory with gauge group SU(6). If this symmetry is first broken to SU(5) at a fixed point and then further reduced to the standard model group in the above non-local way, the two light Higgs doublets of the MSSM are predicted by the group-theoretical and geometrical structure of the model.

    1990-01-01

    We evaluate some constraints on the construction of grand unified superstring theories (GUSTs) using higher level Kac-Moody algebras on the world-sheet. In the most general formulation of the heterotic string in four dimensions, an analysis of the basic GUST model-building constraints, including a realistic hidden gauge group, reveals that there are no E 6 models and any SO(10) models can only exist at level-5. Also, any such SU(5) models can exist only for levels 4≤k≤19. These SO(10) and SU(5) models risk having many large, massless, phenomenologically troublesome representations. We also show that with a suitable hidden sector gauge group, it is possible to avoid free light fractionally charged particles, which are endemic to string derived models. We list all such groups and their representations for the flipped SU(5)xU(1) model. We conclude that a sufficiently binding hidden sector gauge group becomes a basic model-building constraint.

  20. A unified grand tour of theoretical physics

    CERN Document Server

    Griffiths, J

    2002-01-01

    Anyone offering a grand tour is faced with several options. Should they concentrate on what may be considered to be essential features, or should they attempt to present a brief glimpse of almost everything? The present offering is a compromise between these two extremes. The area considered - theoretical physics - is now such a vast subject that some kind of compromise is essential. Indeed, the field is now so wide that few could even attempt to review it in a single-authored work. My task here is to assess how well this book has succeeded in its main aim of providing a unified (though introductory) tour of this subject. Constrained within a single volume, this is clearly not an updated Landau-Lifschitz. It cannot be expected to take any particular topic to the level of recent research. Nevertheless, it does seem to cover the broad range of essential topics which now constitute the subject. It starts (most appropriately in my opinion) with geometry. It then covers classical physics, general relativity and qu...

    Poor workflow associated with physician rounding can produce inefficiencies that decrease time for essential activities, delay clinical decisions, and reduce staff and patient satisfaction. Workflow and provider resources were not optimized when a pediatric intensive care unit increased by 22,000 square feet (to 33,000) and by nine beds (to 30). Lean methods (focusing on essential processes) and scenario analysis were used to develop and implement a patient-centric standardized rounding process, which we hypothesize would lead to improved rounding efficiency, decrease required physician resources, improve satisfaction, and enhance throughput. Human factors techniques and statistical tools were used to collect and analyze observational data for 11 rounding events before and 12 rounding events after process redesign. Actions included: 1) recording rounding events, times, and patient interactions and classifying them as essential, nonessential, or nonvalue added; 2) comparing rounding duration and time per patient to determine the impact on efficiency; 3) analyzing discharge orders for timeliness; 4) conducting staff surveys to assess improvements in communication and care coordination; and 5) analyzing customer satisfaction data to evaluate impact on patient experience. Thirty-bed pediatric intensive care unit in a children's hospital with academic affiliation. Eight attending pediatric intensivists and their physician rounding teams. Eight attending physician-led teams were observed for 11 rounding events before and 12 rounding events after implementation of a standardized lean rounding process focusing on essential processes. Total rounding time decreased significantly (157 ± 35 mins before vs. 121 ± 20 mins after), through a reduction in time spent on nonessential (53 ± 30 vs. 9 ± 6 mins) activities. The previous process required three attending physicians for an average of 157 mins (7.55 attending physician man-hours), while the new process required two

    Purpose Factors that support self-efficacy must be understood in order to foster family-centered care (FCC) during rounds. Based on social cognitive theory, this study examined (1) how 3 supportive experiences (observing role models, having mastery experiences, and receiving feedback) influence self-efficacy with FCC during rounds and (2) whether the influence of these supportive experiences was mediated by self-efficacy with 3 key FCC tasks (relationship building, exchanging information, and decision making). Method Researchers surveyed 184 students during pediatric clerkship rotations during the 2008–2011 academic years. Surveys assessed supportive experiences and students’ self-efficacy with FCC during rounds and with key FCC tasks. Measurement models were constructed via exploratory and confirmatory factor analyses. Composite indicator structural equation (CISE) models evaluated whether supportive experiences influenced self-efficacy with FCC during rounds and whether self-efficacy with key FCC tasks mediated any such influences. Results Researchers obtained surveys from 172 eligible students who were 76% (130) White and 53% (91) female. Observing role models and having mastery experiences supported self-efficacy with FCC during rounds (each pFCC tasks, relationship building and decision making (each p FCC during rounds. Conclusions Observing role models and having mastery experiences foster students’ self-efficacy with FCC during rounds, operating through self-efficacy with key FCC tasks. Results suggest the importance of helping students gain self-efficacy in key FCC tasks before the rounds experience and helping educators implement supportive experiences during rounds.

    A three-generation Pati-Salam model is constructed by compactifying the heterotic string on a particular T 6 /Z 6 Abelian symmetric orbifold with two discrete Wilson lines. The compactified space is taken to be the Lie algebra lattice G 2 -bar SU(3)-bar SO(4). When one dimension of the SO(4) lattice is large compared to the string scale, this model reproduces many features of a 5d SO(10) grand unified theory compactified on an S 1 /Z 2 orbifold. (Of course, with two large extra dimensions we can obtain a 6d SO(10) grand unified theory.) We identify the orbifold parities and other ingredients of the orbifold grand unified theories in the string model. Our construction provides a UV completion of orbifold grand unified theories, and gives new insights into both field theoretical and string theoretical constructions

    A total of 829 spiral galaxies in 22 clusters having redshifts between z = 0.02 and 0.06 were classified according to the appearance of their spiral arm structures. The fraction of galaxies that have a grand design spiral structure was found to be higher among barred galaxies than among non-barred galaxies (at z = 0.02, 95 per cent of strongly barred galaxies have a grand design, compared with 67 per cent of non-barred or weakly barred galaxies). Cluster galaxies and distant non-cluster galaxies have the same fraction of grand design galaxies when resolution effects are considered. The grand design fraction among cluster galaxies is also similar to the fraction observed among nearby galaxies in binary systems and in groups. (author)

    Attending rounds is a key component of patient care and education at teaching hospitals, yet there is an absence of studies addressing trainees' perceptions of rounds. To determine perceptions of pediatrics and internal medicine residents about the current and ideal purposes of inpatient rounds on hospitalist services. In this multi-institutional qualitative study, the authors conducted focus groups with a purposive sample of internal medicine and pediatrics residents at 4 teaching hospitals. The constant comparative method was used to identify themes and codes. The study identified 4 themes: patient care, clinical education, patient/family involvement, and evaluation. Patient care included references to activities on rounds that forwarded care of the patient. Clinical education pertained to teaching/learning on rounds. Patient/family involvement encompassed comments about incorporating patients and families on rounds. Evaluation described residents demonstrating skill for attendings. Resident perceptions of the purposes of rounds aligned with rounding activities described by prior observational studies of rounds. The influence of time pressures and the divergent needs of participants on today's rounds placed these identified purposes in tension, and led to resident dissatisfaction in the achievement of all of them. Suboptimal congruency exists between perceived resident clinical education and specialty-specific milestones. These findings suggest a need for education of multiple stakeholders by (1) enhancing faculty teaching strategies to maximize clinical education while minimizing inefficiencies; (2) informing residents about the value of patient interactions and family-centered rounds; and (3) educating program directors in proper alignment of inpatient rotational objectives to the milestones.

    Some restrictions imposed upon Grand Unified Theories by dynamical symetry breakdown are examined. They are shown that, in particular, theories SU(5) as symmetry group, with 3 or more fermion families undergo dynamical symmetry breakdown, and some of the fermions will acquire mass at the Grand Unified scale. On the other hand, the SO(10) group, with 3 families is free from this problem. (Author) [pt

    The impact of parity coverage on the quantity of behavioral health services used by enrollees and on the prices of these services was examined in a set of Federal Employees Health Benefit (FEHB) Program plans. After parity implementation, the quantity of services used in the FEHB plans declined in five service categories, compared with plans that did not have parity coverage. The decline was significant for all service types except inpatient care. Because a previous study of the FEHB Program found that total spending on behavioral health services did not increase after parity implementation, it can be inferred that average prices must have increased over the period. The finding of a decline in service use and increase in prices provides an empirical window on what might be expected after implementation of the federal parity law and the parity requirement under the health care reform law.

    Full Text Available This paper analyzed how the main economies have used the antidumping measures (AD after the Uruguay round, between 1995 and 2012. Therefore, some techniques were employed in order to reveal the main AD users and the trend, of using this instrument, associated to each one of them. We also tested the hypothesis that countries could converge in terms of the number of AD cases and if spatial effects could be involved in this process. Finally, a criterion was established and a model was estimated in order to identify countries that usually favor the most competitive sectors through AD practice. The results revealed that Brazil was the only heavy AD user that was counter to the general downward trend verified on the AD cases. Meanwhile, China was not only the main target of this mechanism but the cases against this country showed a growth trend also. Furthermore, we found that the number of AD cases opened by traditional and nontraditional users is converging. Finally, both the index and the estimated model have indicated that Turkey and the EU seem to be favoring the most competitive industries through the AD practice.

  20. Wind Turbine Gearbox Condition Monitoring Round Robin Study - Vibration Analysis

    2012-07-01

    The Gearbox Reliability Collaborative (GRC) at the National Wind Technology Center (NWTC) tested two identical gearboxes. One was tested on the NWTCs 2.5 MW dynamometer and the other was field tested in a turbine in a nearby wind plant. In the field, the test gearbox experienced two oil loss events that resulted in damage to its internal bearings and gears. Since the damage was not severe, the test gearbox was removed from the field and retested in the NWTCs dynamometer before it was disassembled. During the dynamometer retest, some vibration data along with testing condition information were collected. These data enabled NREL to launch a Wind Turbine Gearbox Condition Monitoring Round Robin project, as described in this report. The main objective of this project was to evaluate different vibration analysis algorithms used in wind turbine condition monitoring (CM) and find out whether the typical practices are effective. With involvement of both academic researchers and industrial partners, the project sets an example on providing cutting edge research results back to industry.

    Desmoplastic Small Round Cell Tumor (DSRCT) is a rare sarcoma tumor of adolescence and young adulthood, which harbors a recurrent chromosomal translocation between the Ewing's sarcoma gene (EWSR1) and the Wilms' tumor suppressor gene (WT1). Patients usually develop multiple abdominal tumors with liver and lymph node metastasis developing later. Survival is poor using a multimodal therapy that includes chemotherapy, radiation and surgical resection, new therapies are needed for better management of DSRCT. Triggering cell apoptosis is the scientific rationale of many cancer therapies. Here, we characterized for the first time the expression of pro-apoptotic receptors, tumor necrosis-related apoptosis-inducing ligand receptors (TRAILR1-4) within an established human DSRCT cell line and clinical samples. The molecular induction of TRAIL-mediated apoptosis using agonistic small molecule, ONC201 in vitro cell-based proliferation assay and in vivo novel orthotopic xenograft animal models of DSRCT, was able to inhibit cell proliferation that was associated with caspase activation, and tumor growth, indicating that a cell-based delivery of an apoptosis-inducing factor could be relevant therapeutic agent to control DSRCT.

    Full Text Available Introduction. Most implantable hearing aids currently available were developed to compensate the sensorineural hearing loss by driving middle ear structures (e.g., the ossicles. These devices are successfully used in round window (RW stimulation clinically, although this was initially not the intended use. Here, a novel microactuator, specifically designed for RW stimulation, was tested in human temporal bones to determine actuator performance and applicability. Methods. Stapes footplate response to RW stimulation was determined experimentally in human temporal bones and the obtained sound pressure output level was estimated. Results. The actuator had a flat displacement response between 0.125 and 4 kHz, a resonance between 4 and 7 kHz, and a roll-off above. At increasing contact force, the stapes footplate displacement decreased by 5–10 dB re μm for forces ≥ 2 mN. The equivalent sound pressure level between 0.125 and 4 kHz amounted to 87–97 eq dB SPL and increased to 117 eq dB SPL for frequencies of 4–7 kHz. The total harmonic distortion (THD of the actuator ranged within 15–40% for static forces of 5 mN. Conclusion. The feasibility of an electromagnetic actuator that may be placed into the RW niche was demonstrated but requires further optimization in terms of THD and static force sensitivity.

    A yearly multi-round, multi-period, multi-product transmission rights (TR) auction issuing both point-to-point Financial Transmission Rights (FTRs) and Flow-Gate Rights (FGRs) is studied in this paper. In each round the TR market participants (buyers or sellers) submit their bid or offer prices based on past energy market performance. A Locational Marginal Pricing (LMP) based energy market is assumed. The TR market participants' bid or offer prices reflect their expectation of the average annual LMP differences between withdrawal and injections points for FTRs and of the transmission link capacity prices for FGRs. The TR auction is performed in four rounds; in each round 25% of the entire system capability is awarded. TRs that are awarded in one round are modeled as fixed injections in subsequent rounds. Market participants that have acquired TRs in one round can sell them in subsequent rounds. A market participant can submit bids or offers for on-peak, off-peak or 24-h TRs. A three-area, nine-bus test system with six TR market participants is used for the analysis of the TR auction. (author)

    2015-05-01

    Full Text Available A novel implementation of code based cryptography (Cryptocoding technique for multi-layer key distribution scheme is presented. VLSI chip is designed for storing information on generation of round keys. New algorithm is developed for reduced key size with optimal performance. Error Control Algorithm is employed for both generation of round keys and diffusion of non-linearity among them. Two new functions for bit inversion and its reversal are developed for cryptocoding. Probability of retrieving original key from any other round keys is reduced by diffusing nonlinear selective bit inversions on round keys. Randomized selective bit inversions are done on equal length of key bits by Round Constant Feedback Shift Register within the error correction limits of chosen code. Complexity of retrieving the original key from any other round keys is increased by optimal hardware usage. Proposed design is simulated and synthesized using VHDL coding for Spartan3E FPGA and results are shown. Comparative analysis is done between 128 bit Advanced Encryption Standard round keys and proposed round keys for showing security strength of proposed algorithm. This paper concludes that chip based multi-layer key distribution of proposed algorithm is an enhanced solution to the existing threats on cryptography algorithms.

    2017-06-01

    Teaching rounds are rarely featured in the surgery clerkship. Senior students interested in surgery are suited to precept teaching rounds. Near-peer teaching can provide benefits to both learners and preceptors. Near-peer teaching rounds consisted of senior student-precetors leading groups of 3 clerkship students on teaching rounds once during the clerkship. We prospectively surveyed student satisfaction before and after instituting near-peer teaching rounds. We retrospectively gathered qualitative narratives from student-preceptors. The survey response rate was 93% before near-peer teaching rounds were instituted and 85% after. Satisfaction with the learning environment and the quality and amount of small-group teaching were significantly higher after the institution of near-peer teaching rounds (P ≤ .001 for all 3). Satisfaction with the overall clerkship and baseline interest in surgery were not significantly different. Student-preceptors reported gaining valuable experience for future roles in academia as residents and attending surgeons. Student satisfaction with small-group teaching and the learning environment increased after the institution of near-peer teaching rounds in the surgery clerkship. Student-preceptors gained early experience for careers in academic surgery. Copyright © 2016 Elsevier Inc. All rights reserved.

    2013-01-01

    This paper presents a novel poly (PC) and active (RX) corner rounding modeling approach to SPICE simulations. A set of specially designed structures was used for measurement data collection. PC and RX corner rounding equations have been derived based on an assumption that the corner rounding area is a fragment of a circle. The equations were modified to reflect the gouging effect of physical silicon wafers. The modified general equations were implemented in the SPICE model to enable the model to describe the corner rounding effect. The good fittings between the SPICE model simulation results and the silicon data demonstrated in this paper proved that the designed corner rounding model is practical and accurate.

    The Grand Canyon is one of North America's most spectacular geologic features. Carved primarily by the Colorado River over the past six million years, the canyon sports vertical drops of 5,000 feet and spans a 445-kilometer-long stretch of Arizona desert. The strata along the steep walls of the canyon form a record of geologic time from the Paleozoic Era (250 million years ago) to the Precambrian (1.7 billion years ago).The above view was acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument aboard the Terra spacecraft. Visible and near infrared data were combined to form an image that simulates the natural colors of water and vegetation. Rock colors, however, are not accurate. The image data were combined with elevation data to produce this perspective view, with no vertical exaggeration, looking from above the South Rim up Bright Angel Canyon towards the North Rim.

    The implementation of interdisciplinary teams in the intensive care unit (ICU) has focused attention on leadership behavior. Daily interdisciplinary rounds (IDRs) in ICUs integrate leadership behavior and interdisciplinary teamwork. The purpose of this intervention study was to measure the effect of leadership training on the quality of IDRs in the ICU. A nonrandomized intervention study was conducted in four ICUs for adults. The intervention was a 1-day training session in a simulation environment and workplace-based feedback sessions. Measurement included 28 videotaped IDRs (total, 297 patient presentations) that were assessed with 10 essential quality indicators of the validated IDR Assessment Scale. Participants were 19 intensivists who previously had no formal training in leading IDRs. They were subdivided by cluster sampling into a control group (ten experienced intensivists) and intervention group (nine intensive care fellows). Mann-Whitney U test was used to compare results between control and intervention groups. Baseline measurements of control and intervention groups revealed two indicators that differed significantly. The frequency of yes ratings for the intervention group significantly increased for seven of the ten indicators from before to after intervention. The frequency of yes ratings after training was significantly greater in the intervention than control groups for eight of the ten essential quality indicators. The leadership training improved the quality of the IDRs performed in the ICUs. This may improve quality and safety of patient care.

    Purpose: Desmoplastic small round-cell tumor (DSRCT) is a rare, recently described intraperitoneal malignancy occurring predominantly in adolescent boys. Our objective was to evaluate the feasibility and outcome of whole abdominopelvic irradiation (WAPI) as part of a combined modality protocol for patients with DSRCT. Methods and Materials: The records of all 21 patients treated with WAPI for DSRCT at our institution from 1992 to 2001 were retrospectively reviewed. Patients were treated on an institutional protocol with 7 cycles of an alkylator-based chemotherapy. After maximal surgical debulking, patients were treated with external beam radiotherapy to the whole abdomen and pelvis to a dose of 30 Gy. Results: All 21 patients completed the prescribed treatment. The median follow-up was 28 months. The overall survival and relapse-free survival rate at 3 years was 48% and 19%, respectively. The median survival was 32 months, and the median time to relapse was 19 months. Most relapses were intraperitoneal and/or hepatic. Acute toxicities included Radiation Therapy Oncology Group Grade 2 upper and lower gastrointestinal toxicity in 81% and 71% of patients, respectively. All patients experienced acute hematologic toxicity, with Grade 4 thrombocytopenia, leukopenia, and anemia in 76%, 29%, and 33%, respectively. The major long-term toxicity was small bowel obstruction, which occurred in 7 patients (33%) after surgery and WAPI. Conclusion: DSRCT is a rare and highly lethal disease, requiring aggressive multimodality therapy. WAPI is feasible in conjunction with intensive chemotherapy and surgery. Hematologic and gastrointestinal toxicities are expected but manageable with diligent supportive care. The long-term efficacy of this therapy remains disappointing, thus novel approaches are being investigated

  2. NUFACT11 Round Table Discussion — Questions and Answers

    2013-01-01

    This presents the response to questions formulated by a round table discussion panel to the NUFACT11 participants. The main points made were as follows. Neutrino mass is physics beyond the Standard Model; it presents a very deep puzzle to solve, with the answers to several fundamental questions as potential reward. Precision measurement of oscillation parameters is one essential way to access information needed to solve this puzzle and there is a relatively clear (but not easy) way forward. Large θ 13 makes the appearance signals larger, but does not allow to relax the requirements on high beam intensity and large detector masses; it creates a difficult challenge on systematic errors, which will require dedicated ancillary experiments. Of particular interest is a low intensity muon storage ring for required cross-section measurements. There exist already extended bottom-up international collaboration in both physics and R and D experiments. All three main regions have plans for upgraded super-beams and associated detectors, with a variety of (mostly) complementary baselines, proceeding in an incremental way. The ultimate precision and verification of the neutrino mixing picture requires new types of neutrino beams based on storage rings. For low energy neutrinos, the beta-beam is a possible (but substantial) intermediate step. The Neutrino Factory offers the best precision and best sensitivity to deviations from the standard picture. Coordinated international R and D is pursued. International collaboration at the top level would be beneficial in acknowledging the process, so as make sure that intermediate steps are effectively building up in complementary fashion towards the ultimate goals.

  3. Homogenous BSCCO-2212 Round Wires for Very High Field Magnets

    2012-01-01

    The performance demands on modern particle accelerators generate a relentless push towards higher field magnets. In turn, advanced high field magnet development places increased demands on superconducting materials. Nb3Sn conductors have been used to achieve 16 T in a prototype dipole magnet and are thought to have the capability for ∼18 T for accelerator magnets (primarily dipoles but also higher order multipole magnets). However there have been suggestions and proposals for such magnets higher than 20 T. The High Energy Physics Community (HEP) has identified important new physics opportunities that are enabled by extremely high field magnets: 20 to 50 T solenoids for muon cooling in a muon collider (impact: understanding of neutrinos and dark matter); and 20+ T dipoles and quadrupoles for high energy hadron colliders (impact: discovery reach far beyond present). This proposal addresses the latest SBIR solicitation that calls for grant applications that seek to develop new or improved superconducting wire technologies for magnets that operate at a minimum of 12 Tesla (T) field, with increases up to 15 to 20 T sought in the near future (three to five years). The long-term development of accelerator magnets with fields greater than 20 T will require superconducting wires having significantly better high-field properties than those possessed by current Nb 3 Sn or other A15 based wires. Given the existing materials science base for Bi-2212 wire processing, we believe that Bi 2 Sr 2 CaCu 2 O y (Bi-2212) round wires can be produced in km-long piece lengths with properties suitable to meet both the near term and long term needs of the HEP community. The key advance will be the translation of this materials science base into a robust, high-yield wire technology. While the processing and application of A15 materials have advanced to a much higher level than those of the copper oxide-based, high T c (HTS) counterparts, the HTS materials have the very significant advantage

    The Grand Canal, also known as the Beijing-Hangzhou Grand Canal, is a UNESCO World Heritage Site and the longest canal in the world. It is an important trunk line of the South-to-North Water Diversion Project in China. The contamination status and spatial distributions of perfluoroalky substances (PFASs) in waters of the Grand Canal were investigated. The total concentrations of PFASs (∑PFASs) range from 7.8 ng/L to 218.0 ng/L, with high ∑PFASs occurring in the southern part of the Grand Canal which is located in a highly urbanized and economically developed region. The dominance of PFOA showed a decreasing trend toward north while shorter chain homologue proportions increased in the northern part of the Canal which mainly traverses underdeveloped and rural areas in Eastern China. Positive correlations were observed between ∑PFASs and the population density as well as GDP per capita. Intersection with large rivers may affect the contamination levels and composition of PFASs in the water of the Grand Canal near the intersection sites. Copyright © 2017 Elsevier Ltd.

  5. Flocculent and grand design spiral galaxies in groups: time scales for the persistence of grand design spiral structures

    Elmegreen, B.G.; Elmegreen, D.M.

    1983-01-01

    Spiral arm classifications were made for 261 low-inclination galaxies in groups listed by Huchra and Geller. The fractional occurrence of grand design spiral structure in nonbarred galaxies was found to increase from approx.0.1 to approx.0.6 and then level off as the group crossing rate or galaxy collision rate in a group increases. A simple model is discussed where the random encounters between galaxies of any type and flocculent galaxies induce transient grand design spirals in the flocculent galaxies. If this grand-design stimulation occurs for binary collisions with impact parameters less than αR 25 , were R 25 is the galactic radius at 25 mag arcsec - 2 , and if the induced grand design spirals persist for an average time equal to #betta# galactic rotations, then the quantity α 2 #betta# equals approximately 3 x 10 4 . If binary collisions are responsible for grand design spirals, then this result implies either that the induced spirals last for many galactic rotations (#betta#>15), or that they can be stimulated by very remote encounters (α>45.) Alternatively, grand design spirals may be stimulated by multiple galaxy encounters, which would be the case for such large α, or by interactions with the potential well of the associated group, rather than by simple binary encounters. Weak correlations between the grand design fraction and the galaxy size, or between this fraction and the total number of galaxies in a group, were also found. Spiral structures of barred galaxies show no correlations with group environment

    2005-01-01

    In this work, we study SO(10) grand unification in its full extent by using different explicit matrix representations which exhibit the structure of SO(10) in a very transparent way. Our approach consists mainly of two stages: We derive the explicit expressions of the mass-eigenvalues and mass-eigenstates of the physical gauge bosons from a mass squared-matrix that contains all the information about the mixing parameters among the gauge fields and the phases which are sources for CP violation. In the light of this analysis, we derive the explicit expressions for the interaction Lagrangians of the charged currents, the neutral currents and the charged and colored currents in SO(10). We present explicit expressions of the vector and axial-vector couplings of the two neutral currents in SO(10). We show how the baryon, lepton and baryon minus lepton number violating processes and their explicit CP violating phases are accommodated in the SO(10) theory. The Higgs potential that we use to implement in the Higgs mechanism is constructed in a most general fashion through a careful study of the Higgs fields of SO(10), where we give special emphasis on illustrating the explicit matrix representation of these Higgs fields. The potential part of the Higgs Lagrangian will give us the properties of the minimum of the vacuum, and the kinetic part will give us the mass-squared matrix of the gauge bosons via spontaneous symmetry breakdown. The same Higgs multiplets will be coupled to fermions through a democratic Yukawa matrix. Thereby, we derive explicit expressions for the fermion masses of the third family including Majorana and Dirac masses for neutrinos. We introduce a flavor-eigenbasis for neutrinos and find the mass-eigenstates and mass-eigenvalues of the neutrinos. Explicit expressions for CP violation in the neutrino sector are obtained. In the second stage of our work, we evaluate all the above mentioned quantities. In addition, we present the values of the physical

    A single-layer two-way grid shell defined by Bezier surface is optimized by coordinates of the control points as design variables. The purpose of this paper is to find optimal shapes considering roundness and elastic stiffness, and to investigate their mechanical properties. The distance of the center of curvature from the specified point is used for formulating the objective function for generating a round shape. Consider next a problem of minimizing the compliance as mechanical performance measure. The compliance is defined by the external work against the static loads applied to the nodes. The mechanically optimal shape is different from the round shape. Therefore, the multi objective optimization problem is formulated for optimizing the two objectives, which are roundness and the elastic stiffness defined by using the compliance. The constraint method is used for obtaining Pareto optimal solutions between the two objectives. We optimize single-layer two-way grid shells with square and rectangle plans. Mechanical properties of the optimal shapes are investigated by compliance and the distributions of axial force and bending moment. The round shape is significantly dominated by the bending moment and its compliance is large. The bending moment of the mechanically optimal shape is not very large, and the latticed shell has large stiffness through axial deformation. A trade-off shape is round enough, and the influence of the bending moment is smaller than that of the optimal round shape and the elastic stiffness is moderately large

    Full Text Available The reproductive biology of round sardinella, Sardinella aurita Valenciennes, 1847, was studied for the first time in the north-eastern Mediterranean Sea. Round sardinella has gained much attention lately because of its biomass increase, which might be the result of climatic changes occurring across the Mediterranean Sea. Monthly samples were collected on board commercial purse-seiners for two complete year cycles (September 2000 to August 2002. Round sardinella is a gonochoristic fish. The overall female to male ratio was not statistically different (P=0.34 from unity, although it varied monthly and with the length of the fish. The seasonal changes in the gonadosomatic index and the macroscopic characteristics of gonads showed that round sardinella in the northern Aegean spawns between May and July. Male round sardinella reach first sexual maturity at a smaller total length than females (155.0 and 168.3 mm respectively. Mean absolute fecundity (FA increased exponentially with body length (FA=0.0949xL4.22 and weight (FA=511.19xW1.02, with an average of ~21,000 oocytes produced per spawning female. Relative fecundity (FR ranged between 242 and 681 oocytes/g of body weight (average: 445 oocytes/g. The frequency distribution of oocytes showed that round sardinella produces a single batch of oocytes. In general, the reproductive characteristics of round sardinella in the north-eastern Mediterranean Sea differed when compared to stocks from other areas of its distribution.

    The medical student's experience with patients' dying and death has profound impact on personal and professional development. Death Rounds at the University of New Mexico School of Medicine is a small group educational model that promotes student self-reflection, metacognition, professional growth, and collegial support. To describe the implementation and evaluation activities of a third year clerkship Death Rounds which are a structured, institutionally supported resource for helping students to understand the clinical, ethical, legal, professional, cultural, and spiritual aspects of death. Medical students attend 2 to 3 small group palliative medicine Death Rounds sessions, facilitated by the attending clerkship director, chief residents, and a palliative care physician. The students' assessment of their palliative medicine knowledge and skills in 5 categories before and after participation in Death Rounds rated their skills after Death Rounds higher with effect sizes ranging from 0.9 to 1.9. Evidence from both the Death Rounds Questionnaire and Facilitators' Logs demonstrates that multiple issues and topics were addressed and all associated with the School of Medicine's 6 core competencies. Death Rounds minimally affect on clerkship time and faculty resources.

    Lu, Jiqiang; Kim, Jongsung

    SHACAL-2 is a 64-round block cipher with a 256-bit block size and a variable length key of up to 512 bits. It is a NESSIE selected block cipher algorithm. In this paper, we observe that, when checking whether a candidate quartet is useful in a (related-key) rectangle attack, we can check the two pairs from the quartet one after the other, instead of checking them simultaneously; if the first pair does not meet the expected conditions, we can discard the quartet immediately. We next exploit a 35-round related-key rectangle distinguisher with probability 2-460 for the first 35 rounds of SHACAL-2, which is built on an existing 24-round related-key differential and a new 10-round differential. Finally, taking advantage of the above observation, we use the distinguisher to mount a related-key rectangle attack on the first 44 rounds of SHACAL-2. The attack requires 2233 related-key chosen plaintexts, and has a time complexity of 2497.2 computations. This is better than any previously published cryptanalytic results on SHACAL-2 in terms of the numbers of attacked rounds.

    To evaluate the impact of the adaptation of an existing electronic referral application for use in antimicrobial stewardship prospective audit and feedback rounds (antimicrobial rounds). Retrospective, single-centre observational study between March 2015 and February 2016. A new quaternary referral centre. Adults referred for antimicrobial rounds outside of the intensive care and haematology units. Adaptation of an electronic referral application used by medical and allied health staff. A questionnaire-style referral form was designed to capture patient clinical details using a combination of free text and dropdown menus. Clinical pharmacists were educated and granted access to the system. The proportion of completed electronic referrals of total round reviews by month for the 12 months after implementation. The time from request to completion of reviews. The impact on adherence to advice provided on rounds. The impact on the institutional usage of broad-spectrum antibiotics: glycopeptides, carbapenems, third and fourth generation cephalosporins, fluoroquinolones and piperacillin/tazobactam. Over the study period, the proportion of electronic referrals of completed antimicrobial round reviews increased from 59% to 88% (P < 0.001); 75.7% of accepted electronic referrals were seen within 48 h of request. The proportion of advice ignored fell from 18% to 8.5% (P < 0.001). Piperacillin/tazobactam, fluoroquinolone and glycopeptide usage decreased. The adaptation of an electronic referral application for antimicrobial rounds was associated with increased adherence to advice and reduction in use in target antibiotics. Our model is now used at other institutions.

    While there are numerous benefits of smartphone use for physicians, little is known about the negative effects of using these devices in the context of patient care. To assess resident and faculty smartphone use during inpatient attending rounds and its potential as a source of distraction during transfer of clinical information. Cross-sectional survey. University-affiliated public teaching hospital. All housestaff and inpatient faculty in the departments of Medicine and Pediatrics. Participants were asked about smartphone ownership, usage patterns during attending rounds, and whether team members had ever missed important data during rounds due to distraction from smartphones. Attendings were asked whether policies should be established for smartphone use during rounds. The overall response rate was 73%. Device ownership was prevalent (89% residents, 98% faculty), as was use of smartphones during inpatient rounds (57% residents, 28% attendings). According to self-reports, smartphones were used during rounds for patient care (85% residents, 48% faculty), reading/responding to personal texts/e-mails (37% residents, 12% faculty), and other non-patient care uses (15% residents, 0% faculty). Nineteen percent of residents and 12% of attendings believed they had missed important information because of distraction from smartphones. Residents and faculty agreed that smartphones "can be a serious distraction during attending rounds," and nearly 80% of faculty believed that smartphone policies should be established. Smartphone use during attending rounds is prevalent and can distract users during important information transfer. Attendings strongly favored the institution of formal policies governing appropriate smartphone use during inpatient rounds. Copyright © 2012 Society of Hospital Medicine.

    Accurately communicating patient data during daily ICU rounds is critically important since data provide the basis for clinical decision making. Despite its importance, high fidelity data communication during interprofessional ICU rounds is assumed, yet unproven. We created a robust but simple methodology to measure the prevalence of inaccurately communicated (misrepresented) data and to characterize data communication failures by type. We also assessed how commonly the rounding team detected data misrepresentation and whether data communication was impacted by environmental, human, and workflow factors. Direct observation of verbalized laboratory data during daily ICU rounds compared with data within the electronic health record and on presenters' paper prerounding notes. Twenty-six-bed academic medical ICU with a well-established electronic health record. ICU rounds presenter (medical student or resident physician), interprofessional rounding team. None. During 301 observed patient presentations including 4,945 audited laboratory results, presenters used a paper prerounding tool for 94.3% of presentations but tools contained only 78% of available electronic health record laboratory data. Ninty-six percent of patient presentations included at least one laboratory misrepresentation (mean, 6.3 per patient) and 38.9% of all audited laboratory data were inaccurately communicated. Most misrepresentation events were omissions. Only 7.8% of all laboratory misrepresentations were detected. Despite a structured interprofessional rounding script and a well-established electronic health record, clinician laboratory data retrieval and communication during ICU rounds at our institution was poor, prone to omissions and inaccuracies, yet largely unrecognized by the rounding team. This highlights an important patient safety issue that is likely widely prevalent, yet underrecognized.

    Faculty in the Division of Hospital Medicine provide most of the clinical teaching for learners at our institution. The majority of these faculty are Assistant Professors with limited formal instruction in clinical teaching. Previous Divisional strategies to improve clinical teaching ability included discussion of effective teaching behaviors, developing written expectations for teaching faculty, and instituting seminars on effective clinical teaching. Heretofore, the Division had not utilized a direct observation exercise. We developed a direct observation exercise to encourage discussion of teaching techniques and contemplation of change. Using a social learning model, we developed a peer-to-peer observation followed by a nonevaluative discussion. We created a tool for describing teaching behaviors in 5 domains that were similar to or different from the usual behavior of the observing peer: learner presentations, team leadership, bedside teaching, professionalism, and other. After the observation, the observing and observed faculty met to discuss observed teaching behaviors. Both faculty members discussed and then recorded any teaching behaviors that they planned to adopt or change. We implemented this intervention in a 22-member Academic Division of Hospital Medicine at a tertiary care medical center in the United States. A high proportion were junior faculty and graduates of our residency program. We reviewed records of 28 of 31 observations that were completed during the initial 9-month period of implementation and later surveyed faculty. The exercise resulted in planned changes in teaching behaviors that included instituting new methods to improve teaching team leadership, triaging of patients seen on rounds, faculty behaviors during oral presentations, giving real-time feedback, use of technology and humor, demonstrating physical examination findings, and modeling professional behaviors. Faculty later reported adoption of new teaching behaviors that were

    The Mesaba Energy Project is a nominal 600 MW integrated gasification combine cycle power project located in Northeastern Minnesota. It was selected to receive financial assistance pursuant to code of federal regulations (?CFR?) 10 CFR 600 through a competitive solicitation under Round 2 of the Department of Energy?s Clean Coal Power Initiative, which had two stated goals: (1) to demonstrate advanced coal-based technologies that can be commercialized at electric utility scale, and (2) to accelerate the likelihood of deploying demonstrated technologies for widespread commercial use in the electric power sector. The Project was selected in 2004 to receive a total of $36 million. The DOE portion that was equally cost shared in Budget Period 1 amounted to about $22.5 million. Budget Period 1 activities focused on the Project Definition Phase and included: project development, preliminary engineering, environmental permitting, regulatory approvals and financing to reach financial close and start of construction. The Project is based on ConocoPhillips? E-Gas? Technology and is designed to be fuel flexible with the ability to process sub-bituminous coal, a blend of sub-bituminous coal and petroleum coke and Illinois # 6 bituminous coal. Major objectives include the establishment of a reference plant design for Integrated Gasification Combined Cycle (?IGCC?) technology featuring advanced full slurry quench, multiple train gasification, integration of the air separation unit, and the demonstration of 90% operational availability and improved thermal efficiency relative to previous demonstration projects. In addition, the Project would demonstrate substantial environmental benefits, as compared with conventional technology, through dramatically lower emissions of sulfur dioxide, nitrogen oxides, volatile organic compounds, carbon monoxide, particulate matter and mercury. Major milestones achieved in support of fulfilling the above goals include obtaining Site, High Voltage

    The inner layer of the round window membrane is composed of mesothelial cells and this mesothelial cell layer extends to the scala tympani. This study describes the histopathologic findings of temporal bone analysis from a patient with bilateral perilymphatic fistula of the round window membrane. The left ear showed proliferation of mesothelial cells in the scala tympani of the basal turn adjoining the round window membrane. This cell proliferation is thought to be a reaction to the rupture of the round window membrane.

    1991-08-01

    The Grand Junction Projects Office (GJPO) is located in Mesa County, Colorado, immediately south and west of the Grand Junction city limits. The US Atomic Energy Commission (AEC) established the Colorado Raw Materials Office at the present-day Grand Junction Projects Office in 1947, to aid in the development of a viable domestic uranium industry. Activities at the site included sampling uranium concentrate; pilot-plant milling research, including testing and processing of uranium ores; and operation of a uranium mill pilot plant from 1954 to 1958. The last shipment of uranium concentrate was sent from GJPO in January, 1975. Since that time the site has been utilized to support various DOE programs, such as the former National Uranium Resource Evaluation (NURE) Program, the Uranium Mill Tailings Remedial Action Project (UMTRAP), the Surplus Facilities Management Program (SFMP), and the Technical Measurements Center (TMC). All known contamination at GJPO is believed to be the result of the past uranium milling, analyses, and storage activities. Hazards associated with the wastes impounded at GJPO include surface and ground-water contamination and potential radon and gamma-radiation exposure. This report documents the results of the Baseline Environmental Audit conducted at Grand Junction Projects Office (GJPO) located in Grand Junction, Colorado. The Grand Junction Baseline Environmental Audit was conducted from May 28 to June 12, 1991, by the Office of Environmental Audit (EH-24). This Audit evaluated environmental programs and activities at GJPO, as well as GJPO activities at the State-Owned Temporary Repository. 4 figs., 12 tabs.

    Saturn's internal magnetic field has been puzzling since the first in-situ measurements during the Pioneer 11 Saturn flyby. Cassini magnetometer measurements prior to the Grand Finale phase established 1) the highly axisymmetric nature of Saturn's internal magnetic field with a dipole tilt smaller than 0.06 degrees, 2) at least an order of magnitude slower secular variation rate compared to that of the current geomagnetic field, and 3) expulsion of magnetic fluxes from the equatorial region towards high latitude. The highly axisymmetric nature of Saturn's intrinsic magnetic field not only challenges dynamo theory but also makes an accurate determination of the interior rotation rate of Saturn extremely difficult. The Cassini spacecraft entered the Grand Finale phase in April 2017, during which time the spacecraft dived through the gap between Saturn's atmosphere and the inner edge of the D-ring 22 times before descending into the deep atmosphere of Saturn. The unprecedented proximity to Saturn (reaching 2500 km above the cloud deck) and the highly inclined nature of the Grand Finale orbits provided an ideal opportunity to decode Saturn's internal magnetic field. The fluxgate magnetometer onboard Cassini made precise vector measurements during the Grand Finale phase. Magnetic signals from the interior of the planet, the magnetospheric ring current, the high-latitude field-aligned current (FAC) modulated by the 10.7 hour planetary period oscillation, and low-latitude FACs were observed during the Grand Finale phase. Here we report the magnetometer measurements during the Cassini Grand Finale phase, new features of Saturn's internal magnetic field revealed by these measurements (e.g., the high degree magnetic moments of Saturn, the level of axisymmetry beyond dipole), and implications for the deep interior of Saturn.

  4. Regional economic impacts of Grand Canyon river runners.

    Economic impact analysis (EIA) of outdoor recreation can provide critical social information concerning the utilization of natural resources. Outdoor recreation and other non-consumptive uses of resources are viewed as environmentally friendly alternatives to extractive-type industries. While outdoor recreation can be an appropriate use of resources, it generates both beneficial and adverse socioeconomic impacts on rural communities. The authors used EIA to assess the regional economic impacts of rafting in Grand Canyon National Park. The Grand Canyon region of northern Arizona represents a rural US economy that is highly dependent upon tourism and recreational expenditures. The purpose of this research is twofold. The first is to ascertain the previously unknown regional economic impacts of Grand Canyon river runners. The second purpose is to examine attributes of these economic impacts in terms of regional multipliers, leakage, and types of employment created. Most of the literature on economic impacts of outdoor recreation has focused strictly on the positive economic impacts, failing to illuminate the coinciding adverse and constraining economic impacts. Examining the attributes of economic impacts can highlight deficiencies and constraints that limit the economic benefits of recreation and tourism. Regional expenditure information was obtained by surveying non-commercial boaters and commercial outfitters. The authors used IMPLAN input-output modeling to assess direct, indirect, and induced effects of Grand Canyon river runners. Multipliers were calculated for output, employment, and income. Over 22,000 people rafted on the Colorado River through Grand Canyon National Park in 2001, resulting in an estimated $21,100,000 of regional expenditures to the greater Grand Canyon economy. However, over 50% of all rafting-related expenditures were not captured by the regional economy and many of the jobs created by the rafting industry are lower-wage and seasonal. Policy

    We explore recent observational work which indicate that the energetics of the sun's outer atmosphere have been on a steady decline for the past decade and perhaps longer. Futher, we show that new investigations into evolution of the Sun's global magnetic activity appear to demonstrate a path through which the Sun can go into, and exit from, a grand activity minimum without great difficulty while retaining an activity cycle - only losing sunspots. Are we at the begining of a new grand(-ish) minimum? Naturally, only time will tell, but the observational evidence hint that one may not be far off to what impact on the Sun-Earth Connection.

    Quality assurance ensures that planned treatments eventuate. Programmes must include feedback loops to promptly correct any shortfall in predetermined standards. In March 1999, a weekly Chart Round was introduced to verify that certain items relevant to quality care were being completed for patients of the Head and Neck Radiotherapy Unit at the Peter MacCallum Cancer Institute. The experience was reviewed after 1 year and it was found that the initiation of Chart Rounds has assisted in raising the level of item completion from 80% to 99% in similar groups of patients treated before and after the initiation of the Chart Round. Initiation of the Chart Round has also provided a useful forum for in-house peer-review, education and effective real-time communication between medical and allied health personnel, all of which has further added to the quality of patient care.

    Full Text Available The aim of this brief essay is to focus on the relation between the meaning of reality and illusion in the movie La Grande Illusion (1937 by Jean Renoir and therefore to find how these ideas of the author may be productive in a thought about the imaginary. After a short look on the movies made at that time on the First World War, there is an overview of the French director poetics, which redefines the conception of the realism, contextualizing its work at the point of convergence of two imaginary “technological lines”, the cinema and the aviation. It follows the analysis of the movie and the illusions, as social largely shared imaginaries, described by the author. In the end it is showed the importance and the of illusion in Renoir’s poetics. Beyond the relationship realityfiction, he thought a dynamic reciprocity among illusion and reality: so that the reality is as “illusion” (a ruled horizon in which it is possible to enjoy a world of play and the illusion as an activity creating contents of “reality”.

We aim to explore medical students’ perceptions regarding medical and surgical ward rounds within the Faculty of Medicine at Kuwait University, and to evaluate whether this teaching activity is meeting the expectation of learners. Methods: A pretested questionnaire was used to collect data from 141 medical students during the 2012–2013 academic year. They were asked to provide their current and expected ratings about competencies that were supposed to be gained during ward rounds, on a scale from 1 (lowest to 5 (highest. Mean scores were calculated, and the Student t-test was used to compare results. P < 0.05 was the cut-off level for significance. Results: Only 17 students (12.1% declined to participate in the study. The students' current competency scores (for competencies taught within both disciplines – medical and surgical were significantly lower than the scores indicating students’ expectations (P < 0.001. The best-taught competency was bedside examination, in both medical (mean: 3.45 and surgical (mean: 3.05 ward rounds. However, medical ward rounds were better than surgical rounds in covering some competencies, especially the teaching of professional attitude and approach towards patients (P < 0.001. Conclusion: Both medical and surgical ward rounds were deficient in meeting the students’ expectations. Medical educators should utilize the available literature to improve the bedside

    The Accreditation Council for Graduate Medical Education (ACGME) has established the requirement for residency programs to assess trainees' competencies in 6 core domains (patient care, medical knowledge, practice-based learning, interpersonal skills, professionalism, and systems-based practice). As attending rounds serve as a primary means for educating trainees at academic medical centers, our study aimed to identify current rounding practices and attending physician perceived capacity of different rounding models to promote teaching within the ACGME core competencies. We disseminated a 24-question survey electronically using educational and hospital medicine leadership mailing lists. We assessed attending physician demographics and the frequency with which they used various rounding models, as defined by the location of the discussion of the patient and care plan: bedside rounds (BR), hallway rounds (HR), and card-flipping rounds (CFR). Using the ACGME framework, we assessed the perceived educational value of each model. We received 153 completed surveys from attending physicians representing 34 institutions. HR was used most frequently for both new and established patients (61% and 43%), followed by CFR for established patients (36%) and BR for new patients (22%). Most attending physicians indicated that BR and HR were superior to CFR in promoting the following ACGME competencies: patient care, systems-based practice, professionalism, and interpersonal skills. HR is the most commonly employed rounding model. BR and HR are perceived to be valuable for teaching patient care, systems-based practice, professionalism, and interpersonal skills. CFR remains prevalent despite its perceived inferiority in promoting teaching across most of the ACGME core competencies. © 2014 Society of Hospital Medicine.

    On routine coronal images, we have recognized atrophied hippocampi that appear round in patients with Alzheimer's disease (AD). The purpose of this study was to evaluate rounding of the hippocampus in patients with AD and to elucidate whether this change is a useful radiological marker of atrophy of the hippocampus. We enrolled 14 patients with moderate AD (Mini-Mental State Examination score 16.2±3.3) and 15 patients without dementia or neurological deficits as the control group. For measurement of the hippocampus, we used T2-weighted coronal images parallel to the floor of the fourth ventricle. Two observers measured the dimensions of the long and short axes of the hippocampal body of 28 hippocampi from 14 patients with AD and 30 hippocampi from 15 controls. As a marker of rounding of the hippocampal body, we calculated the ratio of the short axis length to the long axis length (the rounding ratio) of the hippocampus. We observed apparent atrophy of the long axis of the hippocampus in patients with AD. An unpaired t-test indicated significant differences in the long axis length and the rounding ratio between the control and AD groups (P<0.01) in the measurements of both observers. However, there was no significant difference in the short axis length. With a threshold of 0.7 in the rounding ratio, the sensitivity was 85.7% and the specificity was 66.7%. The hippocampus appears round on coronal images in the presence of moderate AD. The rounding ratio of the hippocampus is a useful and facile indicator of hippocampal atrophy. (author)

  10. Transient Side Load Analysis of Out-of-Round Film-Cooled Nozzle Extensions

    2012-01-01

    There was interest in understanding the impact of out-of-round nozzle extension on the nozzle side load during transient startup operations. The out-of-round nozzle extension could be the result of asymmetric internal stresses, deformation induced by previous tests, and asymmetric loads induced by hardware attached to the nozzle. The objective of this study was therefore to computationally investigate the effect of out-of-round nozzle extension on the nozzle side loads during an engine startup transient. The rocket engine studied encompasses a regeneratively cooled chamber and nozzle, along with a film cooled nozzle extension. The computational methodology is based on an unstructured-grid, pressure-based computational fluid dynamics formulation, and transient inlet boundary flow properties derived from an engine system simulation. Six three-dimensional cases were performed with the out-of-roundness achieved by three different degrees of ovalization, elongated on lateral y and z axes: one slightly out-of-round, one more out-of-round, and one significantly out-of-round. The results show that the separation line jump was the primary source of the peak side loads. Comparing to the peak side load of the perfectly round nozzle, the peak side loads increased for the slightly and more ovalized nozzle extensions, and either increased or decreased for the two significantly ovalized nozzle extensions. A theory based on the counteraction of the flow destabilizing effect of an exacerbated asymmetrical flow caused by a lower degree of ovalization, and the flow stabilizing effect of a more symmetrical flow, created also by ovalization, is presented to explain the observations obtained in this effort.

    Full Text Available Kroyeria brasiliense sp. nov. from the shark, Galeorhinus vitaminicus de Buen, 1950, from Rio Grande do Sul, State, Brazil, is described on the basis of 14 adult females. The new species is superficially similar to Kroyeria deetsi Dippenaar, Benz & Olivier, 2000, but differs from it in the following characters. The maxillipeds of the new species are large and project well beyond the lateral margins of the cephalothorax. Those of K. deetsi are much smaller. The third endopodal segments of K. deetsi are twice as long as the second endopodal segments and are provided with prominent marginal denticles. The second and third endopodal segments of the new species are rounded, of similar length and lack teeth.Kroyeria brasiliense sp. nov. proveniente de guelras de G. vitaminicus de Buen, 1950 do Rio Grande do Sul, é descrita baseada em 14 fêmeas adultas. A nova espécie aproxima-se de Kroyeria deetsi Dippenaar, Benz & Oliver, 2000, mas a nova espécie se distingue por apresentar os maxilípedes grandes e estendendo-se bem além das margens do cefalotorax. Os terceiros segmentos dos endopoditos de K. deetsi são duas vezes mais cumpridos que os segundos e têm dentículos marginais proeminentes. Os segundos e terceiros segmentos dos endopoditos da nova espécie são arredondados, de tamanhos parecidos e carecem de dentículos.

    Baseline results of the Studio OSservazionale (SOS), observational study, a single-arm observational study of digital chest tomosynthesis for lung cancer detection in an at-risk population demonstrated a detection rate of lung cancer comparable to that of studies that used low dose CT scan (LDCT). We present the results of the first round. Totally 1,703 out of 1,843 (92%) subjects who had a baseline digital chest tomosynthesis underwent a first round reevaluation after 1 year. At first round chest digital tomosynthesis, 13 (0.7%) subjects had an indeterminate nodule larger than 5 mm and underwent low-dose CT scan for nodule confirmation. PET/CT study was obtained in 10 (0.5%) subjects and 2 subjects had a low-dose CT follow up. Surgery, either video-assisted thoracoscopic or open surgery for indeterminate pulmonary nodules was performed in 10 (0.2%) subjects. A lung cancer was diagnosed and resected in five patients. The lung cancer detection rate at first round was 0.3% (5/1,703). The detection rate of lung cancer at first round for tomosynthesis is comparable to rates reported for CT. In addition, results of first round digital chest tomosynthesis confirm chest tomosynthesis as a possible first-line lung cancer-screening tool.

    The problem of visibility reduction in the Grand Canyon due to fine organic aerosol particles in the atmosphere has become an area of increased environmental concern. Aerosol particles can be derived from many emission sources. In this report, we focus on identifying organic aerosols derived from common vegetation in the Grand Canyon. These aerosols are expected to be significant contributors to the total atmospheric organic aerosol content. Aerosol samples from living vegetation were collected by resuspension of surface wax and resin components liberated from the leaves of vegetation common to areas of the Grand Canyon. The samples were analyzed using high-resolution gas chromatography/mass spectrometry (GC/MS). Probable identification of compounds was made by comparison of sample spectra with National Institute of Standards and Technology (NIST) mass spectral references and positive identification of compounds was made when possible by comparison with authentic standards as well as NIST references. Using these references, we have been able to positively identify the presence of n-alkane and n-alkanoic acid homolog series in the surface waxes of the vegetation sampled. Several monoterpenes, sesquiterpenes, and diterpenes were identified also as possible biogenic aerosols which may contribute to the total organic aerosol abundance leading to visibility reduction in the Grand Canyon

    2014-10-01

    Effective cardiopulmonary resuscitation saves lives. Health professionals who care for acutely unwell children need to be prepared to care for a child in arrest. Hospitals must ensure that their staff have the knowledge, confidence and ability to respond to a child in cardiac arrest. RESUS4KIDS is a programme designed to teach paediatric resuscitation to health care professionals who care for acutely unwell children. The programme is delivered in two components: an e-learning component for pre-learning, followed by a short, practical, face-to-face course that is taught using the round-the-table teaching approach. Round-the-table teaching is a novel, evidence-based small group teaching approach designed to teach paediatric resuscitation skills and knowledge. Round-the-table teaching uses a structured approach to managing a collapsed child, and ensures that each participant has the opportunity to practise the essential resuscitation skills of airway manoeuvres, bag mask ventilation and cardiac compressions. Round-the-table teaching is an engaging, non-threatening approach to delivering interdisciplinary paediatric resuscitation education. The methodology ensures that all participants have the opportunity to practise each of the different essential skills associated with the Danger, Response, Send for help, Airway, Breathing, Circulation, Defibrillation or rhythm recognition (DRSABCD) approach to the collapsed child. Round-the-table teaching is based on evidence-based small group teaching methods. The methodology of round-the-table teaching can be applied to any topic where participants must demonstrate an understanding of a sequential approach to a clinical skill. Round-the-table teaching uses a structured approach to managing a collapsed child. © 2014 The Authors.

    The increasing prevalence of mobile devices in clinical settings has the potential to improve both patient care and education. The benefits are particularly promising in the context of family-centered rounds in inpatient pediatric settings. We aimed to increase mobile device usage by inpatient rounding teams by 50% in 6 months. We hoped to demonstrate that use of mobile devices would improve access to patient care and educational information and to determine if use would improve efficiency and perceptions of clinical teaching. We designed a mixed-methods study involving pre- and post-implementation surveys to residents, families, and faculty as well as direct observations of family-centered rounds. We conducted rapid cycles of continual quality improvement by using the Plan-Do-Study-Act framework involving 3 interventions. Pre-intervention, the mobile computing cart was used for resident education on average 3.3 times per rounding session. After cycle 3, teaching through the use of mobile devices increased by ∼79% to 5.9 times per rounding session. On the basis of survey data, we determined there was a statistically significant increase in residents' perception of feeling prepared for rounds, receiving teaching on clinical care, and ability to teach families. Additionally, average time spent per patient on rounds decreased after implementation of mobile devices. Integration of mobile devices into a pediatric hospital medicine teaching service can facilitate patient care and perception of resident teaching by extending the utility of electronic medical records in care decisions and by improving access to knowledge resources.

    One way to support healthcare staff in handling ethically difficult situations is through ethics rounds that consist of discussions based on clinical cases and are moderated by an ethicist. Previous research indicates that the handling of ethically difficult situations in the workplace might have changed after ethics rounds. This, in turn, would mean that the "ethical climate", i.e. perceptions of how ethical issues are handled, would have changed. To investigate whether ethics rounds could improve the ethical climate perceived by staff working in psychiatry outpatient clinics. In this quasi-experimental study, six inter-professional ethics rounds led by a philosopher/ethicist were conducted at two psychiatry outpatient clinics. Changes in ethical climate were measured at these clinics as well as at two control clinics at baseline and after the intervention period using the instrument Hospital Ethical Climate Survey. Within-groups comparisons of median sum scores of ethical climate showed that no statistically significant differences were found in the intervention group before or after the intervention period. The median sum scores for ethical climate were significantly higher, both at baseline and after the intervention period (P ≤ 0.001; P = 0.046), in the intervention group. Ethics rounds in psychiatric outpatient clinics did not result in significant changes in ethical climate. Outcomes of ethics rounds might, to a higher degree, be directed towards patient-related outcomes rather than towards the staff's working environment, as the questions brought up for discussion during the ethics rounds concerned patient-related issues.

    The China Grand Canal is one of the earliest canals in the world, having lasted for nearly 3000 years. Even its section canals have a rich history, such as the North-South Grand Canal that was established during the Sui Dynasty, whereas the Beijing-Hangzhou Canal was excavated during the Yuan Dynasty and the east line of the South-to-North Water Diversion. As one of the longest in the world, the China Grand Canal's total length is over 3500 kilometers. This length includes the navigable, unnavigable, and underground sections. Making the best use of situations and according to local conditions, the Chinese people harmoniously constructed the Beijing-Hangzhou Canal with nature. Tens of millions of workers took nearly 3000 years to complete the great shipping system. Navigable sections still exist for up to 900 kilometers and the volume of freight traffic is approximately 300 million tons. The canal remains the main logistical channel of the North-to-South Coal Transportation, South-to-North Water Diversion, and resources circulation. To date, China is promoting the success of heritage application. Part of these efforts is the declaration of the China Grand Canal as a World Cultural Heritage by 2014. In addition, the east route of the South-to-North Water Transfer project is planned to be navigable by 2016. The ancient Beijing-Hangzhou Grand Canal will usher in the new ecological civilization and cultural revival along the canal. This paper presents technical methods of water environment evolution research on the river system, river, and water quality along the Beijing-Hangzhou Canal through the integration of historical literature and modern remote sensing image data. The study carried out water environment investigation and analysis along the Beijing-Hangzhou canal by using ETM, SPOT image data, and GPS measurement data.

    To characterize the extent of measurement error arising from rounding in headache frequency reporting (days per month) in a population sample of headache sufferers. When reporting numerical health information, individuals tend to round their estimates. The tendency to round to the nearest 5 days when reporting headache frequency can distort distributions and engender unreliability in frequency estimates in both clinical and research contexts. This secondary analysis of the 2005 American Migraine Prevalence and Prevention study survey characterized the population distribution of 30-day headache frequency among community headache sufferers and determined the extent of numerical rounding ("heaping") in self-reported data. Headache frequency distributions (days per month) were examined using a simplified version of Wang and Heitjan's approach to heaping to estimate the probability that headache sufferers round to a multiple of 5 when providing frequency reports. Multiple imputation was used to estimate a theoretical "true" headache frequency. Of the 24,000 surveys, headache frequency data were available for 15,976 respondents diagnosed with migraine (68.6%), probable migraine (8.3%), or episodic tension-type headache (10.0%); the remainder had other headache types. The mean number of headaches days/month was 3.7 (standard deviation = 5.6). Examination of the distribution of headache frequency reports revealed a disproportionate number of responses centered on multiples of 5 days. The odds that headache frequency was rounded to 5 increased by 24% with each 1-day increase in headache frequency (odds ratio: 1.24, 95% confidence interval: 1.23 to 1.25), indicating that heaping occurs most commonly at higher headache frequencies. Women were more likely to round than men, and rounding decreased with increasing age and increased with symptoms of depression. Because of the coarsening induced by rounding, caution should be used when distinguishing between episodic and chronic

    Multi-round PCR is an important technique for obtaining enough target DNA from rare DNA resources, and is commonly used in many fields including forensic science, ancient DNA analysis and cancer research. However, multi-round PCR is often aborted, largely due to the accumulation of non-specific amplification during repeated amplifications. Here, we developed a Pfu polymerase based multi-round PCR technique assisted by quantum dots (QDs). Different PCR assays, DNA polymerases (Pfu and Taq), DNA sizes and GC amounts were compared in this study. In the presence of QDs, PCR specificity could be retained even in the ninth-round amplification. Moreover, the longer and more complex the targets were, the earlier the abortion happened in multi-round PCR. However, no obvious enhancement of specificity was found in multi-round PCR using Taq DNA polymerase. Significantly, the fidelity of Pfu polymerase based multi-round PCR was not sacrificed in the presence of QDs. Besides, pre-incubation at 50 °C for an hour had no impact on multi-round PCR performance, which further authenticated the hot start effect of QDs modulated in multi-round PCR. The findings of this study demonstrated that a cost-effective and promising multi-round PCR technique for large-scale and high-throughput sample analysis could be established with high specificity, sensibility and accuracy.

  5. Measurement Rounding Errors in an Assessment Model of Project Led Engineering Education

    2009-11-01

    Full Text Available This paper analyzes the rounding errors that occur in the assessment of an interdisciplinary Project-Led Education (PLE process implemented in the Integrated Master degree on Industrial Management and Engineering (IME at University of Minho. PLE is an innovative educational methodology which makes use of active learning, promoting higher levels of motivation and students’ autonomy. The assessment model is based on multiple evaluation components with different weights. Each component can be evaluated by several teachers involved in different Project Supporting Courses (PSC. This model can be affected by different types of errors, namely: (1 rounding errors, and (2 non-uniform criteria of rounding the grades. A rigorous analysis of the assessment model was made and the rounding errors involved on each project component were characterized and measured. This resulted in a global maximum error of 0.308 on the individual student project grade, in a 0 to 100 scale. This analysis intended to improve not only the reliability of the assessment results, but also teachers’ awareness of this problem. Recommendations are also made in order to improve the assessment model and reduce the rounding errors as much as possible.

    Large aperture ({phi}200 - {phi}250) cylindrical beam ducts consisting of alumina ceramics will be used in the 3 GeV-synchrotron of High Intensity Proton Accelerator Facility. In particular, bending magnet sections require the large length ({approx}3500 mm) ceramic beam duct connecting several unit ducts whose length is around 500-1000 mm by metallizing and glazing. Therefore it is very important to evaluate roundness and straightness of ceramic ducts because we have to compensate contact area large and have to minimize misalignment of ducts connected. We developed an apparatus for measuring roundness and straightness, and we completed data analysis method using general application software Excel as well as measuring method. Then we have taken data, and have evaluated value of roundness and straightness for the first time about 7 pieces (3 kinds) of ceramic beam duct. At last we have found out that unit ceramic ducts can be made after sintering without polishing with roundness several hundred micron ({mu}m) and straightness around 0.2-1 mm, and that straightness has a tendency to become large as duct length increases as well as roundness increases directly proportional to the maximum oblateness.

  7. In-situ roundness measurement and correction for pin journals in oscillating grinding machines

    Yu, Hongxiang; Xu, Mengchen; Zhao, Jie

    2015-01-01

    In the mass production of vehicle-engine crankshafts, pin chasing grinding using oscillating grinding machines is a widely accepted method to achieve flexible and efficient performance. However, the eccentric movement of pin journals makes it difficult to develop an in-process roundness measurement scheme for the improvement of contour precision. Here, a new in-situ roundness measurement strategy is proposed with high scanning speed. The measuring mechanism is composed of a V-block and an adaptive telescopic support. The swing pattern of the telescopic support and the V-block is analysed for an equal angle-interval signal sampling. Hence roundness error signal is extracted in frequency domain using a small-signal model of the V-block roundness measurement method and the Fast Fourier Transformation. To implement the roundness data in the CNC coordinate system of an oscillating grinding machine, a transformation function is derived according to the motion model of pin chasing grinding methodology. Computer simulation reveals the relationship between the rotational position of the crankshaft component and the scanning angle of the displacement probe on the V-block, as well as the influence introduced by the rotation centre drift. Prototype investigation indicates the validity of the theoretical analysis and the feasibility of the new strategy.

    2017-06-01

    Background The purpose of clinical audits performed in radiology units is to reduce the radiation dose of patients and staff and to implement evidence-based best practices. Purpose To describe auditor recommendations in three Finnish clinical audit rounds performed in 2002-2014, and to determine if auditor recommendations have had any impact on improving medical imaging practice. Material and Methods The retrospective observational study was performed in radiology units holding a radiation safety license issued by the Finnish Radiation and Nuclear Safety Authority. The data comprised a systematic sample (n = 120) of auditor reports produced in three auditing rounds in these units during the years 2002-2014. The data were analyzed by descriptive methods and by using the Friedman two-way ANOVA test. Results The number of auditor recommendations given varied between clinical audit rounds and according to the type of imaging unit, as well as according to calculation method. Proportionally, the most recommendations in all three clinical audit rounds were given about defining and using quality assurance functions and about guidelines and practices for carrying out procedures involving radiation exposure. Demanding radiology units improved their practices more than basic imaging units towards the third round. Conclusion Auditor recommendations help to address the deficiencies in imaging practices. There is a need to develop uniform guidelines and to provide tutoring for clinical auditors in order to produce comparable clinical audit results.

    There is a paucity of literature evaluating the effects of family member presence during bedside medical rounds in the pediatric intensive care unit. We hypothesized that, when compared with rounds without family members, parental presence during morning medical rounds would increase time spent on rounds, decrease medical team teaching/education, increase staff dissatisfaction, create more stress in family members, and violate patient privacy in our open unit. Prospective, blinded, observational study. Academic pediatric intensive care unit with 12 beds. A total of 105 admissions were studied, 81 family members completed a survey, and 187 medical team staff surveys were completed. Investigators documented parental presence and time allocated for presentation, teaching, and answering questions. Surveys related to perception of goals, teaching, and privacy of rounds were distributed to participants. Time spent on rounds, time spent teaching on rounds, and medical staff and family perception of the effects of parental presence on rounds. There was no significant difference between time spent on rounds in the presence or absence of family members (p = NS). There is no significant difference between the time spent teaching by the attending physician in the presence or absence of family members (p = NS). Overall, parents reported that the medical team spent an appropriate amount of time discussing their child and were not upset by this discussion. Parents did not perceive that their own or their child's privacy was violated during rounds. The majority of medical team members reported that the presence of family on rounds was beneficial. Parental presence on rounds does not seem to interfere with the educational and communication process. Parents report satisfaction with participation in rounds, and privacy violations do not seem to be a concern from their perspective.

    This synopsis provides the available data concerning the logging models at the DoE-Grand Junction facility, to date (1976). Because gamma-ray logs are used in uranium exploration to estimate the grade (percent U 3 O 8 ) and the thickness of uranium ore zones in exploration drill holes, logging models are required to calibrate the gamma-ray logging equipment in order to obtain accuracy, uniformity, standardization, and repeatability during logging. This quality control is essential for accurate ore reserve calculations and for estimates of ore potential. The logging models at the DoE-Grand Junction facility are available for use by private industry in calibrating their gamma-ray logging equipment. 21 figures, 26 tables

    Particle accelerators are playing an increasingly important role in basic and applied science, and are enabling new accelerator-driven technologies. But the design of next-generation accelerators, such as linear colliders and high intensity linacs, will require a major advance in numerical modeling capability due to extremely stringent beam control and beam loss requirements, and the presence of highly complex three-dimensional accelerator components. To address this situation, the U.S. Department of Energy has approved a ''Grand Challenge'' in Computational Accelerator Physics, whose primary goal is to develop a parallel modeling capability that will enable high performance, large scale simulations for the design, optimization, and numerical validation of next-generation accelerators. In this paper we report on the status of the Grand Challenge

    1981-01-01

    We derive necessary and sufficient conditions to be satisfied by any expanded electroweak gauge model in order to reproduce the standard model low-energy neutral current predictions. These conditions imply several constraints on the neutral gauge boson masses and the quantum number assignments for the ordinary fermions. Using these conditions, we prove that the popular grand unified theories based on the gauge groups SO(10) and E6 can only accommodate trivial extensions of the standard model. As a consequence, if any of these grand unified models works at some energy scale, present low-energy neutral current phenomenology implies that the Z-boson must be produced with the expected mass and couplings to the ordinary fermions. Any additional neutral gauge boson (with the possible exception of very heavy ones) could only be produced in hadronic collisions and it would not decay in e + e - . (orig.)

    Full Text Available Purpose – This paper aims to propose a system for generating actionable knowledge from Big Data and use this system to construct a comprehensive knowledge base (KB, called GrandBase. Design/methodology/approach – In particular, this study extracts new predicates from four types of data sources, namely, Web texts, Document Object Model (DOM trees, existing KBs and query stream to augment the ontology of the existing KB (i.e. Freebase. In addition, a graph-based approach to conduct better truth discovery for multi-valued predicates is also proposed. Findings – Empirical studies demonstrate the effectiveness of the approaches presented in this study and the potential of GrandBase. The future research directions regarding GrandBase construction and extension has also been discussed. Originality/value – To revolutionize our modern society by using the wisdom of Big Data, considerable KBs have been constructed to feed the massive knowledge-driven applications with Resource Description Framework triples. The important challenges for KB construction include extracting information from large-scale, possibly conflicting and different-structured data sources (i.e. the knowledge extraction problem and reconciling the conflicts that reside in the sources (i.e. the truth discovery problem. Tremendous research efforts have been contributed on both problems. However, the existing KBs are far from being comprehensive and accurate: first, existing knowledge extraction systems retrieve data from limited types of Web sources; second, existing truth discovery approaches commonly assume each predicate has only one true value. In this paper, the focus is on the problem of generating actionable knowledge from Big Data. A system is proposed, which consists of two phases, namely, knowledge extraction and truth discovery, to construct a broader KB, called GrandBase.

    Executive SummaryThe U.S. Geological Survey (USGS) has a long history of advancing the traditional Earth science disciplines and identifying opportunities to integrate USGS science across disciplines to address complex societal problems. The USGS science strategy for 2007–2017 laid out key challenges in disciplinary and interdisciplinary arenas, culminating in a call for increased focus on a number of crosscutting science directions. Ten years on, to further the goal of integrated science and at the request of the Executive Leadership Team (ELT), a workshop with three dozen invited scientists spanning different disciplines and career stages in the Bureau convened on February 7–10, 2017, at the USGS John Wesley Powell Center for Analysis and Synthesis in Fort Collins, Colorado.The workshop focused on identifying “grand challenges” for integrated USGS science. Individual participants identified nearly 70 potential grand challenges before the workshop and through workshop discussions. After discussion, four overarching grand challenges emerged:Natural resource security,Societal risk from existing and emerging threats,Smart infrastructure development, andAnticipatory science for changing landscapes.Participants also identified a “comprehensive science challenge” that highlights the development of integrative science, data, models, and tools—all interacting in a modular framework—that can be used to address these and other future grand challenges:Earth Monitoring, Analyses, and Projections (EarthMAP)EarthMAP is our long-term vision for an integrated scientific framework that spans traditional scientific boundaries and disciplines, and integrates the full portfolio of USGS science: research, monitoring, assessment, analysis, and information delivery.The Department of Interior, and the Nation in general, have a vast array of information needs. The USGS meets these needs by having a broadly trained and agile scientific workforce. Encouraging and supporting

    The paleomagnetic measurements of samples from the holes sampled have shown that there are four magnetic correlation lines, between adjacent flows in holes that have distinctly different mean stratigraphic inclinations, and two magnetic polarity boundaries that can be used for magnetic correlation in the Grande Ronde Basalt in the Pasco Basin. The results of paleomagnetic measurements of samples from the Wanapum Basalt and Saddle Mountains Basalt indicate that the potential for magnetostratigraphic correlation in these sequences is also good

    Precise gravity measurements indicate that earth fissures or tension cracks caused by ground-water withdrawal within a 10km2 area SE of Casa Grande are associated with relief on the buried interface between the alluvial aquifer and underlying bedrock. These relations suggest that the fissures are forming in response to localized differential compaction caused by localized variations of aquifer-system thickness. -from Authors

    We present a cosmologically acceptable grand unified model where the breaking of SU(5) proceeds through radiative corrections induced by supergravity soft-breaking terms. The breaking scale is determined by dimensional transmutation. The model is compatible with the radiative breaking of SU(2)sub(L)xU(1)sub(Y) which provides an experimentally accessible low energy particle spectrum and small top quark mass. (orig.)

    Spontaneously broken gauge theories may display distinct vortex string solutions for the disconnected components of the exact gauge symmetry group. A type of Higgs mechanism thought to apply in grand unified theories as being responsible for fermion masses yields Z 2 vortex lines, irrespectively of the group. These could seed galaxy formation if the corresponding fermion masses are superheavy. More generally a Higgs mechanism producing Zsub(n) vortex strings is presented. (orig.)

    The Northwest Power Planning Council (NPPC) identified supplementation as a high priority to achieve its goal of increasing runs of anadromous fish in the Columbia Basin. Supplementation activities in the Lostine River and associated monitoring and evaluation conducted by the Nez Perce Tribe relate directly to the needs addressed in the Columbia River Basin Fish and Wildlife Program (NPPC 1994). Measure 7.4L.1 of the Program mandates that appropriate research accompany any proposed supplementation. In addition, measure 7.3B.2 of the Program stresses the need for evaluating supplementation projects to assess their ability to increase production. Finally, Section 7.4D.3 encourages the study of hatchery rearing and release strategies to improve survival and adaptation of cultured fish. In 1997, Oregon Department of Fisheries and Wildlife (ODFW) requested a modification of Permit 1011 to allow the take of adult spring chinook salmon. In 1998, the Nez Perce Tribe also requested a permit specific to activities on Lostine River. The permit was issued in 2000. A special condition in the permits required the development of a long term management plan for the spring chinook salmon of the Grande Ronde Basin. The Nez Perce Tribe, ODFW, and the Confederated Tribes of the Umatilla Indian Reservation (CTUIR) completed a formal long range plan entitled ''Grande Ronde Basin Endemic Spring Chinook Salmon Supplementation Program''. The program proposes to increase the survival of spring chinook salmon in the Grand Ronde Basin through hatchery intervention. Adult salmon from the Lostine River, Catherine Creek, and the Upper Grande Ronde River are used for a conventional supplementation program in the basin. The Nez Perce program currently operates under the ESA Section 10 Permit 1149.

    The Sun provides the energy necessary to sustain our existence. While the Sun provides for us, it is also capable of taking away. The weather and climatic scales of solar evolution and the Sun-Earth connection are not well- understood. There has been tremendous progress in the century since the discovery of solar magnetism—magnetism that ultimately drives the electromagnetic, particulate, and eruptive forcing of our planetary system. There is contemporary evidence of a decrease in solar magnetism, perhaps even indicators of a significant downward trend, over recent decades. Are we entering a minimum in solar activity that is deeper and longer than a typical solar minimum, a “grand minimum”? How could we tell if we are? What is a grand minimum and how does the Sun recover? These are very pertinent questions for modern civilization. In this paper we present a hypothetical demonstration of entry and exit from grand minimum conditions based on a recent analysis of solar features over the past 20 years and their possible connection to the origins of the 11(&ish) year solar activity cycle.

    1980-01-01

    The Grand Junction Office (GJO), US Department of Energy (DOE), develops and administers programs for evaluating domestic uranium resources and the production capability of industry; for developing resource planning information for DOE; and for advancing geologic and geophysical exploration concepts and techniques. In addition, GJO administers the leasing of mineral lands under DOE control, and carries out activities relating to the environmental aspects of uranium mining and milling, including remedial programs. The Office is staffed by administrative and technical program-management personnel. Bendix Field Engineering Corporation (Bendix) is the DOE operating contractor at the Grand Junction, Colorado, Government-owned/contractor-operated (GOCO) facility. The technical staffs of both GJO and Bendix are primarily geoscience-oriented. Specifically during 1980, uranium resource assessment on 135 National Topographic Map Series (NTMS) quadrangles was completed, along with other specific studies, to yield October 1980 national resource estimates. In addition, updated uranium supply analysis and production capability projections were completed. Another key aspect of this successful program was the development of improved geophysical and geochemical equipment and techniques in support of uranium resource assessment. Much of the hardware and know-how developed was turned over to the public and to the uranium industry at large for application to uranium exploration and the assessment of uranium company resources. The Grand Junction Office also participated actively during 1980 in international cooperative research on uranium exploration techniques and on the geology of uranium deposits

  10. Light grand unified theory triplets and Yukawa splitting

    International Nuclear Information System (INIS)

    Rakshit, Subhendu; Shadmi, Yael; Raz, Guy; Roy, Sourov

    2004-01-01

    Triplet-mediated proton decay in grand unified theories (GUTs) is usually suppressed by arranging a large triplet mass. Here we explore instead a mechanism for suppressing the couplings of the triplets to the first and second generations compared to the Yukawa couplings, so that the triplets can be light. This mechanism is based on a 'triplet symmetry' in the context of product-group GUTs. We study two possibilities. The first possibility, which requires the top Yukawa coupling to arise from a nonrenormalizable operator at the GUT scale, is that all triplet couplings to matter are negligible, so that the triplets can be at the weak scale, giving new evidence for grand unification. The second possibility is that some triplet couplings, and in particular Ttb and Tt-barl-bar, are equal to the corresponding Yukawa couplings. This would give a distinct signature of grand unification if the triplets were sufficiently light. However, we derive a model-independent bound on the triplet mass in this case, which is at least 10 6 GeV. Finally, we construct an explicit viable GUT model based on Yukawa splitting, with the triplets at 10 14 GeV, as required for coupling unification to work. This model requires no additional thresholds below the GUT scale

    Quand l’écrivain Blaise Cendrars fait paraître sa série de poèmes réunis sous le titre Les Grands Fétiches dans la revue bruxelloise Le Disque vert en 1922, il semble participer de la grande mode « Nègre » qui secoue la France en cette période. Co-découvreur des arts dits « primitives » dès 1916...... avec Guillaume Apollinaire, l’écrivain va les insérer dans son travail poétique comme miroirs inversés de la modernité occidentale. Cependant, même s'il utilise certains des clichés racistes de son époque, il se place lui-même dans le camp des « mélanophiles », et va se servir de cet Art Nègre pour...... repousser à l'extrême les frontières de la modernité. La série des Grands Fétiches participe directement de ce désir, et nous tenterons de montrer dans cet article comment ces objets dits primitifs deviennent des objets « instables » qui remettent en question la définition même du poétique....

    1998-01-01

    The authors sampled downstream migrating salmonids at Boggan's Oasis in the Grande Ronde River with a screw trap during 1995 and a scoop trap during 1996. Sampling began in March and terminated early in June. Wild spring chinook and wild/hatchery steelhead were collected and marked to assess migration patterns and timing. Fish were marked with tags in order to obtain downstream migration data with minimal fish handling. Observations were recorded when a fish swam through an interrogation monitor at hydroelectric facilities downstream. The second year for monitoring smolts leaving the Grande Ronde River was completed in 1995. The authors continued to pursue moving to a permanent location downstream for 1997 because of the limitations for trapping smolts at Boggan's Oasis. This involved reconnaissance surveys of several potential sites near the mouth of the river from 1994--1996. During February of 1996, a water velocity and bottom topography assessment was completed. Results of the assessment were used for siting the anchoring tower structure upstream approximately 1.2 miles from the mouth of the Grande Ronde River

    We examined adherence to antimicrobial stewardship prospective audit and feedback rounds in a rehabilitation service compared with the remainder of the acute hospital, and explored the reasons for this. Between October 2014 and December 2015, we retrospectively assessed the rate of non-adherence to advice from antimicrobial stewardship prospective audit and feedback rounds between the rehabilitation service and the acute hospital, along with the source of the patient referral. Compared with the rehabilitation service, acute hospital medical staff were almost twice as likely to not adhere to advice provided on antimicrobial stewardship prospective audit and feedback rounds (13.8% vs. 7.6%, p risk 1.8 [95% confidence interval 1.3, 2.5]). In the rehabilitation service, referrals were more likely to come from medical staff (61.9% vs. 16.3%, p model potentially applicable to other settings.

    The construction project of Korea Geodetic VLBI officially started in October 2008. The construction of all systems will be completed by the end of 2011. The project was named Korea VLBI system for Geodesy (KVG), and its main purpose is to maintain the Korea Geodetic Datum. In case of the KVG system, an observation room with an H-maser frequency standard is located in a building separated from the antenna by several tens of meters. Therefore KVG system will adopt a so-called round-trip system to transmit reference signals to the antenna with reduction of the effect of path length variations. KVG s round-trip system is designed not only to use either metal or optical fiber cables, but also to measure path length variations directly. We present this unique round trip system for KVG.

    Computational geometry has been used to select effective data points from the measured data points for evaluating the roundness error to improve the computational complexity. However, for precision parts most of the measured points are on the vertices of the convex hull; it cannot have any effect on improving the computational complexity with the Voronoi diagrams. In this paper the roundness error is evaluated with α-hull and the Voronoi diagram instead of convex hull. An approach for constructing α-hull with the minimum radius separation is presented to determine the vertices of the Voronoi diagram. The experimental results showed that the roundness error of the minimum zone circle could be solved efficiently with α-hull and the Voronoi diagram

    This paper reports that following licensing efforts in 1989-90, Myanmar has been gearing up with activity both onshore and offshore. The industry gave a strong response to the first round of exploration licensing. The license awards in the first round carried fairly aggressive work commitments in terms of both dollars and timing. Work commitments on each of the first nine blocks ranged from $12 million to $70 million for each block. Most companies committed to spudding their first wells within the first 12-14 months. The drilling results are starting to come in. Although no significant oil discovery has been made yet, the country expects to speed up its exploration activities in the next few years. Following the first round of licensing onshore, Myanmar Oil and Gas Enterprise (MOGE), the national oil company, is negotiating terms for offshore blocks as well as additional onshore blocks for improved oil recovery (IOR) and rehabilitation/redevelopment rights for existing fields

    The safeguard of nuclear material is of paramount importance to the IAEA which increasingly uses this information for characterization purposes in order to strengthen the verification of declared nuclear material and to identify the origin of samples from mines. IAEA tasked CETAMA to conduct a round robin with objective to evaluate the capability of laboratories to measure impurities in uranium with concentration levels between 1 and 500 ppm relative to uranium. This round robin was attended by 17 international laboratories from the nuclear industry and safeguards community. The results are mainly obtained by ICP-MS and ICP-AES. The synthesis of this round robin were helpful in identifying anomalies and will allow the IAEA to better set realistic measurement performance targets for ICP-MS and ICP-AES. (authors)

    Round table discussions are in the tradition of ACAT. This year's plenary round table discussion was devoted to questions related to the use of scientific software in High Energy Physics and beyond. The 90 minutes of discussion were lively, and quite a lot of diverse opinions were spelled out. Although the discussion was, in part, controversial, the participants agreed unanimously on several basic issues in software sharing: (i) The importance of having various licensing models in academic research; (ii) The basic value of proper recognition and attribution of intellectual property, including scientific software; (iii) The user respect for the conditions of use, including licence statements, as formulated by the author. The need of a similar discussion on the issues of data sharing was emphasized and it was recommended to cover this subject at the conference round table discussion of next ACAT. In this contribution, we summarise selected topics that were covered in the introductory talks and in the following discussion.
