  2. Starting a sleep center.

    Epstein, Lawrence J; Valentine, Paul S

    2010-05-01

    The demand for sleep medicine services has grown tremendously during the last decade and will likely continue. To date, growth in demand has been met by growth in the number of new sleep centers. The need for more new centers will be dependent on market drivers that include increasing regulatory requirements, personnel shortages, integration of home sleep testing, changes in reimbursement, a shift in emphasis from diagnostics to treatment, and an increased consumer focus on sleep. The decision to open a new center should be based on understanding the market dynamics, completing a market analysis, and developing a business plan. The business plan should include an overview of the facility, a personnel and organizational structure, an evaluation of the business environment, a financial plan, a description of services provided, and a strategy for obtaining, managing, and extending a referral base. Implementation of the business plan and successful operation require ongoing planning and monitoring of operational parameters. The need for new sleep centers will likely continue, but the shifting market dynamics indicate a greater need for understanding the marketplace and careful planning. PMID:20442123

  3. Financing a Simulation Center.

    Tsuda, Shawn; Mohsin, Adnan; Jones, Daniel

    2015-08-01

    As simulation-based training has become established within medical and health professional disciplines, skills training laboratories have become a standard in surgery training programs. In 2008, the American College of Surgeons and Association of Program Directors in Surgery developed a simulation-based surgical skills curriculum; the Residency Review Committee for Surgery of the Accreditation Council for Graduate Medical Education mandated access to skills laboratories for all surgery programs. Establishing a surgical skills laboratory and adapting the training curriculum requires a significant amount of resources. This article discusses the financial aspects of establishing a training center, from funding opportunities to budgeting considerations. PMID:26210971

  5. Acoustics of a broadcast center

    Beristain, Sergio

    2003-04-01

    A broadcast system in Mexico City had to change facilities in order to concentrate in a single site all related broadcast stations and production studios in order to facilitate its normal operation. This led to a design which included the acoustic noise isolation and the interior acoustics of every studio and control room, together with the audio interconection, the electricity layout, the air conditioning system, the office building, etc. This paper presents the acoustics profile of the center, including final results of the construction as they were measured on completion of the installation. The complex has seven AM and FM broadcast stations, plus seven production studios for news, commercials and radio-novels plus an audio master control room, and everything was completed within four months.

  9. A caveat concerning center of resistance.

    Dathe, Henning; Nägerl, Hans; Kubein-Meesenburg, Dietmar

    2013-01-01

    The center of resistance is a concept in theoretical orthodontics used to describe tooth movement under loads. It is commonly used to qualitatively predict tooth movement without recourse to complex equations or simulations. We start with a survey of the historical origin of the technical term. After this, the periodontal ligament is idealized as a linear elastic suspension. The mathematical formalism of vector and tensor calculus will clarify our reasoning. We show that a point such as the center of resistance basically only exists in two dimensions or in very special symmetric spatial configurations. In three dimensions, a simple counterexample of a suspension without a center of resistance is given. A second more tooth-like example illustrates the magnitude of the effects in question in dentistry. In conclusion, the center of resistance should be replaced by a newer and wider mathematical concept, the "center of elasticity," together with a limiting parameter, the "radius of resistance."

    Full Text Available In the framework of the project Western Eastern Teachers' Education Network (WETEN funded by the Tempus program the network of university teachers were established to share expertise on effective teaching and learning in universities. This network for pedagogical innovation in higher education brought together the experts from EU to share good practice and new teaching methods with academic staff from two eastern countries, Moldova and Ukraine. The learner centered concept was analyzed and guidelines for creating learner centered courses were developed and piloted. The concepts and some experiences in course design were also implemented by trained teachers in the developed courses within the WETEN project.

  12. Establishing a multidisciplinary academic cosmetic center.

    Rao, Venkat K; Schmid, Daniel B; Hanson, Summer E; Bentz, Michael L

    2011-12-01

    The demand for cosmetic services has risen rapidly in recent years, but has slowed down with the current economic downturn. Managed care organizations and Medicare have been steadily reducing their reimbursements for physician services. The payment for reconstructive surgical procedures has been decreasing and is likely to worsen with healthcare reform, and many plastic surgery residency programs are facing fiscal challenges. An adequate volume of patients needing cosmetic services is necessary to recruit and train the best candidates to the residency programs. Self-pay patients will help ensure the fiscal viability of plastic surgery residency programs. Attracting patients to an academic healthcare center will become more difficult in a recession without the appropriate facilities, programs, and pricing strategies. Setting up a modern cosmetic services program at an academic center has some unique challenges, including funding, academic politics, and turf. The authors opened a free-standing academic multidisciplinary center at their medical school 3 years ago. The center is an off-site, 13,000-sq ft facility that includes faculty from plastic surgery, ear, nose, and throat, dermatology, and vascular surgery. In this article, the authors discuss the process of developing and executing a plan for starting an aesthetic services center in an academic setting. The financing of the center and factors in pricing services are discussed. The authors show the impact of the center on their cosmetic surgery patient volumes, resident education, and finances. They expect that their experience will be helpful to other plastic surgery programs at academic medical centers. PMID:22094775

  14. Operating and Managing a Backup Control Center

    Marsh, Angela L.; Pirani, Joseph L.; Bornas, Nicholas

    2010-01-01

    Due to the criticality of continuous mission operations, some control centers must plan for alternate locations in the event an emergency shuts down the primary control center. Johnson Space Center (JSC) in Houston, Texas is the Mission Control Center (MCC) for the International Space Station (ISS). Due to Houston s proximity to the Gulf of Mexico, JSC is prone to threats from hurricanes which could cause flooding, wind damage, and electrical outages to the buildings supporting the MCC. Marshall Space Flight Center (MSFC) has the capability to be the Backup Control Center for the ISS if the situation is needed. While the MSFC Huntsville Operations Support Center (HOSC) does house the BCC, the prime customer and operator of the ISS is still the JSC flight operations team. To satisfy the customer and maintain continuous mission operations, the BCC has critical infrastructure that hosts ISS ground systems and flight operations equipment that mirrors the prime mission control facility. However, a complete duplicate of Mission Control Center in another remote location is very expensive to recreate. The HOSC has infrastructure and services that MCC utilized for its backup control center to reduce the costs of a somewhat redundant service. While labor talents are equivalent, experiences are not. Certain operations are maintained in a redundant mode, while others are simply maintained as single string with adequate sparing levels of equipment. Personnel at the BCC facility must be trained and certified to an adequate level on primary MCC systems. Negotiations with the customer were done to match requirements with existing capabilities, and to prioritize resources for appropriate level of service. Because some of these systems are shared, an activation of the backup control center will cause a suspension of scheduled HOSC activities that may share resources needed by the BCC. For example, the MCC is monitoring a hurricane in the Gulf of Mexico. As the threat to MCC

  15. Aphasia centers in North America: a survey.

    Simmons-Mackie, Nina; Holland, Audrey L

    2011-08-01

    There is a growing trend toward dedicated programs designed to improve the lives of people with aphasia and their families. We are referring to these programs collectively as "aphasia centers." These programs purportedly differ from more traditional medically based aphasia rehabilitation. However, there is no directory of aphasia centers and no definition of what constitutes such a program. Therefore, an online survey was designed to identify and describe aphasia centers in the United States and Canada. A 37-question survey was posted online via SurveyMonkey. An introductory letter was distributed by electronic mail to a listserv and mailing lists of programs associated with aphasia. Potential respondents who considered themselves an aphasia center were asked to complete the survey. A total of 33 survey responses were analyzed, and descriptive data were compiled resulting in a description of the following aspects of aphasia centers: demographic information, mission, admission and discharge policies, assessment practices, program logistics, staffing patterns, marketing, funding, and services offered. In addition, a qualitative analysis of written text responses revealed the following key themes that appear to characterize the responding programs: services that differ from traditional aphasia rehabilitation; a sense of community; a holistic focus on quality of life, psychosocial well-being, participation, and social support; the centrality of group interaction; and variety/intensity of services. PMID:21968557

    Full Text Available With burgeoning reports of adverse drug reactions due to pharmacotherapy, pharmacovigilance (PV is the buzz word in health care circles. While there are experts in this rapidly expanding field, there are many health care professionals who do not fully appreciate the import of PV in the context of modern therapeutics. In view of the national directive to institutionalize a PV center in every medical college of India, there is an urgent need to inform, educate, and enlighten the readers about the constitution and dynamics of a PV center, which this article attempts to fulfill.

  17. In a Rehabilitation Center for Drug Addicts

    1998-01-01

    WHEN China opens its doors to the outside world, fresh air comes in. So do flies. While drug addicts were unknown in China for 30 years, there are now reports of drug users and their related crimes. In an effort to abolish drug abuse in China, rehabilitation centers are being set up throughout the country to give medical aid to drug users trying to kick the habit. These photos were taken in a rehabilitation center in a small town in Gansu Province in the northwestern part of China.

  18. A Computer Learning Center for Environmental Sciences

    Mustard, John F.

    2000-01-01

    In the fall of 1998, MacMillan Hall opened at Brown University to students. In MacMillan Hall was the new Computer Learning Center, since named the EarthLab which was outfitted with high-end workstations and peripherals primarily focused on the use of remotely sensed and other spatial data in the environmental sciences. The NASA grant we received as part of the "Centers of Excellence in Applications of Remote Sensing to Regional and Global Integrated Environmental Assessments" was the primary source of funds to outfit this learning and research center. Since opening, we have expanded the range of learning and research opportunities and integrated a cross-campus network of disciplines who have come together to learn and use spatial data of all kinds. The EarthLab also forms a core of undergraduate, graduate, and faculty research on environmental problems that draw upon the unique perspective of remotely sensed data. Over the last two years, the Earthlab has been a center for research on the environmental impact of water resource use in and regions, impact of the green revolution on forest cover in India, the design of forest preserves in Vietnam, and detailed assessments of the utility of thermal and hyperspectral data for water quality analysis. It has also been used extensively for local environmental activities, in particular studies on the impact of lead on the health of urban children in Rhode Island. Finally, the EarthLab has also served as a key educational and analysis center for activities related to the Brown University Affiliated Research Center that is devoted to transferring university research to the private sector.

  6. A Student-Centered Learning Model

    Mihyar Hesson

    2007-01-01

    Full Text Available Based on the authors experience in applying different approaches of active learning and student-centered teaching, the main problem that prevented the achievement of the full advantages of these approaches is the lack of motivation of students for self-centered learning. A new model for a student-centered learning is presented in this work. This model is of teaching integrative thinking, based on existing models of creativity and synthesis. In this model, the student is put at the heart of a bigger learning process that includes instructors, specialists and the public. Usually students who are in the final year of their study will be the target of the application of this model as a part of a capstone course or final year project. This model promotes the research and thinking skills of the students as well as the gained motivation of self-learning as a result of being in contact with the specialists who might be their potential future employers. A proto-type web-based system based on this model was developed. Although it is applied on a sample of students from the Biology department, the system is readily expandable to any number of other disciplines without any complications or programming overheads. The results achieved from the application of this model were very encouraging.

  10. On characterizations of a center Galois extension

    Lianyong Xue

    2000-06-01

    Full Text Available Let B be a ring with 1,  C the center of B,  G a finite automorphism group of B, and BG the set of elements in B fixed under each element in G. Then, it is shown that B is a center Galois extension of BG (that is, C is a Galois algebra over CG with Galois group G|C≅G if and only if the ideal of B generated by {c−g(c|c∈C} is B for each g≠1 in G. This generalizes the well known characterization of a commutative Galois extension C that C is a Galois extension of CG with Galois group G if and only if the ideal generated by {c−g(c|c∈C} is C for each g≠1 in G. Some more characterizations of a center Galois extension B are also given.

  12. Validation: A Family-Centered Communication Skill.

    Harvey, Pat; Ahmann, Elizabeth

    2016-01-01

    Family-centered care can seem challenging when family member behavior, choices, attitudes, or emotions are "difficult" or "challenging" to deal with. Yet nurses can develop skills to effectively interact with families in a wide variety of circumstances and then become able to practice family-centered care in any situation that might arise. One particularly useful skill is "validation," which means accepting what the family member says or does as a valid expression of thoughts and feelings in that particular circumstance at that particular time. Validation does not mean there is agreement or acceptance of unsafe behaviors, only that the nurse acknowledges that the family member's concerns and feelings are important and should be listened to and taken seriously, even in the presence of disagreement. Validation, which should be individualized, can take many forms, ranging from providing complete attention to reflection of statements, identification of possible unexpressed emotions, normalization, and finally, a full and genuine sense of connection. Understanding and practicing validation can empower nurses and family members, as well as support effectivefamily-centered communication and problem solving even in challenging circumstances.

  13. Lessons learned in simulating a command center

    Mack, Gregory A.; Cantor, Robert M.; Wenzel, Gregory

    1995-06-01

    This paper presents some lessons learned from simulating the operation of a command center in distributed interactive simulations (DIS). We present the design of the Booz Allen Command Center Systems Interface (C2SI) in terms of its functional architecture as well as the technologies used in its implementation. We discuss the design of the distributed component interfaces based on cooperating software agent pairs. We discuss aspects of several issues in simulating command and control systems in the ADS/DIS environment, namely, interoperation of constructive and virtual simulation, situation awareness, communication with adjacent C2 entities, control of subordinate entities and external sensors, terrain/environmental data management, and data collection for after-action reporting.

  19. Establishment of a world food preservation center

    Wilson Charles L

    2013-01-01

    Full Text Available Abstract A World Food Preservation Center (WFPC is proposed in response to a pending civilization-threatening food shortage and our limited ability to adequately increase food production. Some estimates put losses of food in developing countries after it is produced and before it is consumed at 50%. These losses are particularly threatening to individuals and farmers who are living in the midst of food insecurity. Although numerous organizations have attempted to address this problem worldwide, the magnitude of the effort has not come close to the enormity of the problem. Most of these programs are also short-term and require continuous input by postharvest specialists from developed countries in order to be sustainable. A critical need exists for a substantial and sustainable worldwide program that can significantly reduce losses and waste of food in developing countries. The World Food Preservation Center proposed here meets this need by educating young scientists in developing countries about low-input, appropriate technologies for preserving food postharvest. It also conducts research on postharvest technologies especially suited for application in developing countries such as biological control, solar refrigeration, and coordinated transport and marketing schemes that support and sustain the local production of food commodities.

  20. International nuclear service centers: a bibliography

    The literature relating specifically to international nuclear fuel service centers would appear to be relatively scarce, based on the results of searches of the Energy Data Base, the libraries of the University of California at Los Angeles, and The Rand Corporation, and other sources. Works specifically relating to international service centers are annotated in this bibliography. Also listed, without annotation, are studies of various kinds of multinational public enterprises. In addition, there are references to many of the studies of the one-nation nuclear energy center concept. Most of these resulted from the survey of possible sites for these centers mandated by the US Energy Reorganization Act of 1974

  1. Space Operations Center - A concept analysis

    1980-01-01

    The Space Operations Center (SOC) which is a concept for a Shuttle serviced, permanent, manned facility in low earth orbit is viewed as a major candidate for the manned space flight following the completion of an operational Shuttle. The primary objectives of SOC are: (1) the construction, checkout, and transfer to operational orbit of large, complex space systems, (2) on-orbit assembly, launch, recovery, and servicing of manned and unmanned spacecraft, (3) managing operations of co-orbiting free-flying satellites, and (4) the development of reduced dependence on earth for control and resupply. The structure of SOC, a self-contained orbital facility containing several Shuttle launched modules, includes the service, habitation, and logistics modules as well as construction, and flight support facilities. A schedule is proposed for the development of SOC over ten years and costs for the yearly programs are estimated.

  2. A practical application of reliability centered maintenance

    This paper describes a practical and cost effective method for applying Reliability Centered Maintenance (RCM) principles to improve the effectiveness of an existing Preventive Maintenance program. While this program was developed for a modern nuclear power plant, it is based on the premise that many plants already have effective Maintenance and PM Programs, some of which may be relatively comprehensive, even at non-nuclear facilities. Therefore, the objective of this type of upgrade project is to identify and select the most effective PM tasks, whether currently active, or recommended new tasks or revisions, and to eliminate ineffective tasks. Then, apply those changes within the existing programs in a way that will allow the most efficient allocation of resources. It is anticipated that this program will enhance plant safety, improve plant availability and the reliability of plant equipment, as well as prevent escalation of maintenance costs when fully implemented

    T Singh

    2010-01-01

    Full Text Available Background: The cornerstones of successful treatment of hepatoblastoma (HB include preoperative chemotherapy followed by complete anatomical resection of tumor, followed by chemotherapy. Advances in chemotherapy in the last 2 decades have been associated with a higher rate of tumor response and possibly a greater potential for resectability. Aims: We analyzed our single center experience with neoadjuvant chemotherapy (NACT and surgery in HBs. Settings and Design: Our study included all children with HBs who received NACT and underwent surgical excision from January 1997 to July 2004. Materials and Methods: Patient characteristics, clinical features, clinical course, treatment modalities, and long-term outcome were analyzed. Results: There were 9 boys and 3 girls, aged 5-60 months (median age at tumor diagnosis was 24 months. All received NACT containing cisplatin and doxorubicin. Of the 12 children, 9 underwent hepatectomy and among them, 4 patients each had right and left hepatectomy and 1 patient underwent right extended hepatectomy. After surgery, all patients completed rest of the chemotherapy course (total 6 cycles. R0 resection was carried out in all the 9 cases with no life-threatening complications. Conclusions: Our experience of the 9 cases, although less in number, reaffirms the advantages of NACT followed by surgery. The prognosis for patients with resectable tumors is fairly good in combination with chemotherapy.

  10. Pregnancy during Hemodialysis: A Single Center Experience

    Bahadi Abdelali

    2010-01-01

    Full Text Available Successful pregnancy outcome is an uncommon occurrence in women requiring chronic dialysis treatment. We reviewed the course and outcome of 9 pregnancies occurred in women on chronic hemodialysis in our center from 1999-2007; 5 of them ended with delivery of alive newborns, 2 with fetal deaths in-utero, and 2 with abortions. The average age of patients was 34 years. The etiology of the original kidney disease was unknown in 44.4% of the cases, and only 22.2% of the patients maintained diuresis. Dialysis started in 8 cases before the diagnosis of pregnancy. The average gestational age at diagnosis was 14 weeks. We modified the prescription of dialysis in 4 patients by increasing the frequency of the dialysis sessions to 6 per week and in 3 by increasing the duration of each session to 6 hours. Anemia was present in all the cases; 3 patients received erythropoietin and 4 patients required transfusion. The pregnancy was com-plicated in 44% of the cases by a polyhydramnios. The average time at delivery was 33 weeks and it was achieved in 80% of pregnancies through vaginal route. The average weight of newborns was to 2380 g. We conclude that pregnancy in women on hemodialysis is possible. The success of pregnancy may be influenced by the residual diuresis and early diagnosis to improve the quality of dialysis by increasing the dialysis dose.

  11. So You Want to Start a Peer Online Writing Center?

    2013-03-01

    Full Text Available The purpose of this article is to share lessons learned in setting up three different peer online writing centers in three different contexts (EFL, Generation 1.5, and ESL. In each center the focus was on the language learner as a peer online writing advisor and their needs in maintaining centers “for and by” learners. Technology affordances and constraints for local contexts, which promote learner autonomy, are analyzed. The open-source platforms (Moodle, Drupal, and Google Apps are compared in terms of usability for peer writing center work, particularly centers where groups co-construct feedback for writers, asynchronously. This paper is useful for readers who would like a head start or deeper understanding of potential logistics and decision-making involved in establishing a peer online writing center within coursework and/or a self-access learning center.

  12. Interinstitutional transfers to a trauma center.

    Vestrup, J A

    1990-05-01

    To determine patient demographics, referral patterns, and problems with trauma transfer, records of 412 patients received over a 1-year period at the Vancouver General Hospital, a Level I Trauma Center, were reviewed. The average Injury Severity Score (ISS) was 15 (range: 1 to 75), with 142 patients (34%) having an ISS of 16 or greater. One hundred ninety-six (47%) of the transfers were accomplished by fixed-wing aircraft, 15 (4%) by helicopter, and 201 (49%) by land. Seventy-two percent were transported within 24 hours of injury. The injury mechanisms were as follows: 193 (47%) vehicular, 108 (26%) falls, 50 (12%) penetrating, 43 (10%) thermal, and 18 (5%) assaults/crush. Transfer was prompted by musculo-skeletal injuries in 157 (38%), neurosurgical problems in 71 (17%), multiple injuries in 64 (16%), burns in 45 (11%), hand injuries in 27 (7%), facial injuries in 26 (6%), and other problems in 22 (5%). Transfer management problems included airway in 4 patients, respiratory care in 8, and hemodynamic instability in 10. Only two of these patients had an ISS less than 16. Although most transfers were appropriate, some could have been avoided by more careful physician screening. For example, of six patients referred for digit replantation, only one was a suitable candidate. Lack of adequate regional care resulted in 10 long-distance air transports for isolated hip fractures. It is concluded that the majority of transfers were indicated and were safely carried out. However, there is a need for better patient screening, regionalized service, and improved communication regarding appropriate stabilization prior to transfer, particularly for patients with serious injuries.

  18. Medical Center Farmers Markets: A Strategic Partner in the Patient-Centered Medical Home

    Daniel R. George, PhD, MSc

    2013-08-01

    Full Text Available Background The number of medical center���based farmers markets has increased in the past decade, but little is known about how such organizations contribute to the preventive health goals of the patient-centered medical home. Community Context In 2010, we started a seasonal farmers market at Penn State Hershey Medical Center to help support the institution’s commitment to the medical home. Methods We obtained descriptive data on the farmers market from hospital and market records and tracking information on the market’s Facebook and Twitter sites. We computed summary measures to characterize how the market has begun to meet the 6 standards of the 2011 National Committee for Quality Assurance’s report on the medical home. Outcome During the 2010 and 2011 seasons, 146 medical center volunteers from 40 departments formed 23 interprofessional teams that spent an average of 551 volunteer hours per season at the market, providing health screenings (n = 695 and speaking to customers (n = 636 about preventive health. Fifty-five nonmedical community health partners provided 208 hours of service at the market alongside medical center staff. Market programming contributed to 5 regional preventive health partnerships and created opportunities for interprofessional mentoring, student leadership, data management, development of social media skills, and grant-writing experience. The market contributed to all 6 medical home standards outlined by the National Committee for Quality Assurance. Interpretation Medical center markets can support medical home standards. With systematic tracking of the health effects and integration with electronic medical health records, markets hold potential to contribute to comprehensive patient-centered care.

  16. ''Low-temperature'' behavior of a phase-slip center

    The differential resistance of the voltage-current characteristic generated by an isolated phase-slip center in a superconducting tin whisker has been measured down to 50 mK below its critical temperature. As a function of the temperature the differential resistance shows a resonancelike behavior with a maximum at the temperature where charge-imbalance waves excited by the phase-slip center have their maximum decay length, suggesting that the observed maximum of the differential resistance gives experimental evidence for charge-imbalance waves arising from a phase-slip center

  17. Nanoscale fluorescence lifetime imaging with a single diamond NV center

    Beams, Ryan; Johnson, Timothy W; Oh, Sang-Hyun; Novotny, Lukas; Vamivakas, Nick

    2013-01-01

    Solid-state quantum emitters, such as artificially engineered quantum dots or naturally occurring defects in solids, are being investigated for applications ranging from quantum information science and optoelectronics to biomedical imaging. Recently, these same systems have also been studied from the perspective of nanoscale metrology. In this letter we study the near-field optical properties of a diamond nanocrystal hosting a single nitrogen vacancy center. We find that the nitrogen vacancy center is a sensitive probe of the surrounding electromagnetic mode structure. We exploit this sensitivity to demonstrate nanoscale fluorescence lifetime imaging microscopy (FLIM) with a single nitrogen vacancy center by imaging the local density of states of an optical antenna.

  19. Data Center Consolidation: A Step towards Infrastructure Clouds

    Winter, Markus

    Application service providers face enormous challenges and rising costs in managing and operating a growing number of heterogeneous system and computing landscapes. Limitations of traditional computing environments force IT decision-makers to reorganize computing resources within the data center, as continuous growth leads to an inefficient utilization of the underlying hardware infrastructure. This paper discusses a way for infrastructure providers to improve data center operations based on the findings of a case study on resource utilization of very large business applications and presents an outlook beyond server consolidation endeavors, transforming corporate data centers into compute clouds.

  2. A possible role of chemotaxis in germinal center formation

    Beyer, T; Soff, G; Beyer, Tilo; Meyer-Hermann, Michael; Soff, Gerhard

    2002-01-01

    During the germinal center reaction a characteristic morphology is developed. In the framework of a recently developed space-time-model for the germinal center a mechanism for the formation of dark and light zones has been proposed. The mechanism is based on a diffusing differentiation signal which is secerned by follicular dendritic cells. Here, we investigate a possible influence of recently found chemokines for the germinal center formation in the framework of a single-cell-based stochastic and discrete three-dimensional model. We will also consider alternative possible chemotactic pathways that may play a role for the development of both zones. Our results suggest that the centrocyte motility resulting from a follicular dendritic cell-derived chemokine has to exceed a lower limit to allow the separation of centroblasts and centrocytes. In contrast to light microscopy the dark zone is ring shaped. This suggests that FDC-derived chemoattractants alone cannot explain the typical germinal center morphology.

  5. Ghana's experience in the establishment of a national data center

    Ekua, Amponsah Paulina; Yaw, Serfor-Armah

    2012-08-01

    The government of Ghana in a bilateral agreement with the Preparatory Commission for the Comprehensive Nuclear Test-Ban Treaty Organization (CTBTO) has established a National Data Center in Ghana with the aim of monitoring the testing of nuclear explosions. Seismic, hydroacoustic, radionuclide and infrasound methods are used for the monitoring. The data center was commissioned on 3 February, 2010 at the Ghana Atomic Energy Commission. At present Ghana does not have any operational, centralised data (seismic, hydroacoustic, radionuclide and infrasound) acquisition system with the capability of accessing data from other international stations. Hence, the need of setting up the National Data Center which would enable us constantly monitor, manage and coordinate both natural and man-made seismic activities in the country and around the globe, upload data to the International Data Center (IDC) as well as receive and use International Monitoring System (IMS) data and IDC products for treaty verification and compliance. Apart from these, the center also accesses and analyzes seismic waveforms relevant to its needs from the International Data Center; makes data available to its stakeholder institutions for earthquake disaster mitigation; reports on all aspects of disasters related to earthquake to the relevant government agencies that deal with disasters; makes recommendations to the government of Ghana on earthquake safety measures; provides information to assist government institutions to develop appropriate land and building policies. The center in collaboration with stakeholder agencies periodically organises public lectures on earthquake disaster risk mitigation.

  6. The Universe Observing Center a modern center to teach and communicate astronomy

    Ribas, Salvador J.

    2011-06-01

    The Universe Observing Center is one of the parts of the Parc Astronòmic Montsec (PAM). PAM is an initiative of the Catalan government, through the Consorci del Montsec (Montsec Consortium), to take advantage of the capabilities and potential of the Montsec region to develop scientific research, training and outreach activities, particularly in the field of Astronomy. The choice of the Montsec mountains to install the PAM was motivated by the magnificent conditions for observing the sky at night; the sky above Montsec is the best (natural sky free of light pollution) in Catalonia for astronomical observations. The PAM has two main parts: the Observatori Astronòmic del Montsec (OAdM) and the Universe Observing Center (COU). The OAdM is a professional observatory with an 80-cm catadioptric telescope (Joan Oró Telescope). This telescope is a robotic telescope that can be controlled from anywhere in the world via the Internet. The COU is a large multipurpose center which is intended to become an educational benchmark for teaching and communicate astronomy and other sciences in Catalonia. The management of the COU has three main goals: 1) Teach primary and secondary school students in our Educational Training Camp. 2) Teach university students housing the practical astronomy lectures of the universities. 3) Communicate astronomy to the general public. The COU comprises special areas for these purposes: the Telescopes Park with more than 20 telescopes, a coelostat for solar observations and two dome containing full-automated telescopes. The most special equipment is ``The Eye of Montsec'', with its 12m dome containing a multimedia digital planetarium and a platform for direct observation of the sky and the environment. During 2009 we expect around 10000 visitors in Montsec area to enjoy science with Montsec dark skies and an special natural environment.

  14. Human-centered design of a distributed knowledge management system.

    Rinkus, Susan; Walji, Muhammad; Johnson-Throop, Kathy A; Malin, Jane T; Turley, James P; Smith, Jack W; Zhang, Jiajie

    2005-02-01

    Many healthcare technology projects fail due to the lack of consideration of human issues, such as workflow, organizational change, and usability, during the design and implementation stages of a project's development process. Even when human issues are considered, the consideration is typically on designing better user interfaces. We argue that human-centered computing goes beyond a better user interface: it should include considerations of users, functions and tasks that are fundamental to human-centered computing. From this perspective, we integrated a previously developed human-centered methodology with a Project Design Lifecycle, and we applied this integration in the design of a complex distributed knowledge management system for the Biomedical Engineer (BME) domain in the Mission Control Center at NASA Johnson Space Center. We analyzed this complex system, identified its problems, generated systems requirements, and provided specifications of a replacement prototype for effective organizational memory and knowledge management. We demonstrated the value provided by our human-centered approach and described the unique properties, structures, and processes discovered using this methodology and how they contributed in the design of the prototype.

  15. RF Regional Technical Centers for MPC and A Sustainability Operations

    The National Nuclear Security Administration (NNSA) programmatic vision to be a catalyst in Russia's assumption of responsibility for long-term system operation is exemplified in the sustainability cooperation with the RF Ministry of Defense (MOD). An identified goal for the MPC and A Program is to encourage the development of Russian Federation (RF) capabilities and commitments to operate and maintain safeguard improvements. The RF MOD Technical Support Center development fulfills the NNSA mission and MPC and A Program goal. The regional technical center concept involves a systematic approach to aid in the determination of the level of sustainability assistance required to transition operators, maintenance, training, and testing of MPC and A systems to the RF MOD. This paper describes the process used to create the RF MOD Technical support center. First are described the needs analyses conducted to determine the key system sustainability factors requiring support. These sustainability functions are then compiled to influence the form and ultimate physical design of the technical support center. Operational interfaces are described, in detail that show the benefit of the center to the individual sites. Finally, benefits relating to information accessibility and other economies of scale are described that highlight the central center concept's strengths

  20. Finding topological center of a geographic space via road network

    Gao, Liang; Miao, Yanan; Qin, Yuhao; Zhao, Xiaomei; Gao, Zi-You

    2015-02-01

    Previous studies show that the center of a geographic space is of great importance in urban and regional studies, including study of population distribution, urban growth modeling, and scaling properties of urban systems, etc. But how to well define and how to efficiently extract the center of a geographic space are still largely unknown. Recently, Jiang et al. have presented a definition of topological center by their block detection (BD) algorithm. Despite the fact that they first introduced the definition and discovered the 'true center', in human minds, their algorithm left several redundancies in its traversal process. Here, we propose an alternative road-cycle detection (RCD) algorithm to find the topological center, which extracts the outmost road-cycle recursively. To foster the application of the topological center in related research fields, we first reproduce the BD algorithm in Python (pyBD), then implement the RCD algorithm in two ways: the ArcPy implementation (arcRCD) and the Python implementation (pyRCD). After the experiments on twenty-four typical road networks, we find that the results of our RCD algorithm are consistent with those of Jiang's BD algorithm. We also find that the RCD algorithm is at least seven times more efficient than the BD algorithm on all the ten typical road networks.

  2. Mathematica a problem-centered approach

    Hazrat, Roozbeh

    2015-01-01

    This textbook introduces the vast array of features and powerful mathematical functions of Mathematica using a multitude of clearly presented examples and worked-out problems. Each section starts with a description of a new topic and some basic examples. The author then demonstrates the use of new commands through three categories of problems - the first category highlights those essential parts of the text that demonstrate the use of new commands in Mathematica whilst solving each problem presented; - the second comprises problems that further demonstrate the use of commands previously introduced to tackle different situations; and - the third presents more challenging problems for further study. The intention is to enable the reader to learn from the codes, thus avoiding long and exhausting explanations. While based on a computer algebra course taught to undergraduate students of mathematics, science, engineering and finance, the book also includes chapters on calculus and solving equations, and graphics, t...

  3. Role of a circle's center in visual interpolation.

    Huang, Liqiang; Vul, Edward

    2006-07-01

    Basic geometric patterns like straight lines and circles seem fundamental to human perception and mental imagery. In this study we examined subjects' ability to interpolate circular curves-to derive the whole circle from an arc of 180 degrees or less. Specifically, we tested how the center point is utilized during such visual interpolation. Naturally, a mechanism that interpolates by extending the curvature of the visible arc will be unaffected by the presence or absence of the center point. On the other hand, a mechanism that achieves the same end by completing the circle from estimates of the center and radius will be significantly aided by the presence of the center. We found that when the visible arc was long (180 degrees), presenting the circle's center did not affect the precision with which subjects localized the invisible section. However, when the visible arc was relatively short (90 degrees or 45 degrees), displaying the center point significantly increased spatial precision. Thus, both computational mechanisms appear to exist. PMID:16542702

  4. Handcrafting Attachment: A User-Centered Approach

    2011-04-01

    Full Text Available Management, above all, is the controlling element responsible for coordinating the three basic business functions; production, marketing, and finance.  Mechanisms exist to facilitate the finance function with influence coming from outside regulatory bodies such as the AICPA, IIA, SEC, and other regulators.  Integrating the finance function into organizations, then, becomes somewhat generic (although some would argue this point.  Coordinating the functions of marketing and production is a much more difficult endeavor because it lacks the standardization seen in finance.  This paper suggests employing a more user-focused approach as a means to improving the overall quality of products, and eventually, the success of the organization.  Specifically, this paper explores the role of the human brain in the calculus of choice, discusses the role of consumer involvement as it leads to product attachment, and offers suggestions for employing contextual research to improve product design and quality.

    2012-01-01

    Full Text Available Materials and Methods: The study was performed on prospective donors who reported to the Department of Transfusion Medicine. Individuals deferred due to hypertension contributed the study population. They were compared with age and sex matched donor controls. Demographic details were recorded in a proforma. On identification of a hypertensive individual, consequent two comparable donors were taken as controls with a total of 50 hypertensive subjects. Hypertensive status of the subjects were assessed based on the criteria formulated by the WHO-ISH and US Seventh Joint National Committee report on prevention, detection, evaluation and treatment of high blood pressure. Results: About 0.95% of healthy blood donors had undetected hypertension. Mean age at detection of hypertension in the study group was 35.44 ± 7.69 years. Higher BMI was observed in the hypertensive group compared to normotensive control group with P value significant at 0.0001. Conclusion: About 1% of healthy individuals were found to have undetected hypertension. Though the study was not designed to determine the prevalence of hypertension in the region, it is a rough estimate of the proportion of undetected hypertension in the local population as donors are considered as representative of healthy population.

    AIM: To determine the etiology and prognostic factors for neonatal gastric perforation(NGP), a rare but life-threatening disease.METHODS: Between 1980 and 2011, nine patients un-derwent surgical intervention for NGP at Seoul National University Children’s Hospital. The characteristics and prognosis of the patients were retrospectively analyzed.RESULTS: Among the nine patients, three(33.3%) were preterm babies and five(55.5%) had associated anomalies, which included diaphragmatic eventration(n = 2), congenital diaphragmatic hernia, esophageal atresia with tracheoesophageal fistula, and antral web. Three(33.3%) patients were born before 1990 and three(33.3%) had a birth weight < 2500 g. Pneumo-peritoneum was found on preoperative images in six(66.7%) patients, and incidentally in the other three(33.3%) patients. Surgery was performed within 24 h after the onset of symptoms in seven(77.8%) patients. The overall mortality rate was 22.2%(2/9). The time between symptoms and surgical intervention was the only prognostic factor for survival, whereas premature birth and birth weight were not.CONCLUSION: Early detection and advances in neo-natal intensive care may improve the prognosis of NGP.

    2015-06-01

    Full Text Available Objective: Fecal diversion is often indicated in cases with fecal incontinence, Fournier’s gangrene, anal fistula, and inoperable obstructive anorectal cancer. Trephine colostomy can be performed without necessitating laparotomy. We present our experience related to the outcome of trephine sigmoid colostomy. Methods: The retrospective study included 14 patients who underwent trephine colostomy due to various conditions including Fournier’s gangrene, inoperable anorectal cancer, recto-vaginal fistula, and benign stricture due to radiotherapy at our clinic between January 2010 and January 2015. Results: Patients comprised 4 females and 10 males with a mean age of 52.07 years. The indications for stoma formation were Fournier’s gangrene in 7 cases, inoperable anorectal cancer in 5, rectovaginal fistula in 1, and benign stricture due to radiotherapy in 1 case. Eight patients underwent surgery under regional anesthesia. All the patients underwent trephine loop sigmoid colostomy. One patient had second operation on the postoperative period due to colostomy prolapse. The temporary stomas were closed in 3 months. Mean length of hospital stay was 14 days. Conclusion: Trephine stoma is a relatively simple, safe and rapid procedure and an effective alternative to colostomy formation without laparotomy indications. It can be performed under emergency or elective conditions with low morbidity. J Clin Exp Invest 2015; 6 (2: 87-90

  13. The National Center for Atmospheric Research (NCAR) Research Data Archive: a Data Education Center

    Peng, G. S.; Schuster, D.

    2015-12-01

    The National Center for Atmospheric Research (NCAR) Research Data Archive (RDA), rda.ucar.edu, is not just another data center or data archive. It is a data education center. We not only serve data, we TEACH data. Weather and climate data is the original "Big Data" dataset and lessons learned while playing with weather data are applicable to a wide range of data investigations. Erroneous data assumptions are the Achilles heel of Big Data. It doesn't matter how much data you crunch if the data is not what you think it is. Each dataset archived at the RDA is assigned to a data specialist (DS) who curates the data. If a user has a question not answered in the dataset information web pages, they can call or email a skilled DS for further clarification. The RDA's diverse staff—with academic training in meteorology, oceanography, engineering (electrical, civil, ocean and database), mathematics, physics, chemistry and information science—means we likely have someone who "speaks your language." Data discovery is another difficult Big Data problem; one can only solve problems with data if one can find the right data. Metadata, both machine and human-generated, underpin the RDA data search tools. Users can quickly find datasets by name or dataset ID number. They can also perform a faceted search that successively narrows the options by user requirements or simply kick off an indexed search with a few words. Weather data formats can be difficult to read for non-expert users; it's usually packed in binary formats requiring specialized software and parameter names use specialized vocabularies. DSs create detailed information pages for each dataset and maintain lists of helpful software, documentation and links of information around the web. We further grow the level of sophistication of the users with tips, tutorials and data stories on the RDA Blog, http://ncarrda.blogspot.com/. How-to video tutorials are also posted on the NCAR Computational and Information Systems

    Full Text Available Objective: Posterior urethral valves (PUV are the most common cause of bladder outlet obstruction in infancy that impair renal and bladder function. This study was planned to evaluate and record the various clinical presentations and management, complications, and surgical management and long-term outcome of PUV.Methods: In a retrospective study, 98 patients who have been treated for PUV are evaluated in Mofid Children’s Hospital from January 2007 to December 2012. Detailed history taken and paraclinical examinations were performed in each patient and diagnosis was confirmed by voiding-cysto-urethrography (VCUG. PUV had been ablated in 62 patients by electric hook, and diversion was performed in 42 (42.85% cases. Data were analyzed by SPSS software version18.Findings: Totally 98 patients with mean age at diagnosis 62 (±13 days were included in this study. Fifty seven cases had been catheterized within one to 6 days of life (mean age one day, PUV was ablated in 62 patients by electric hook, and diversion was performed in 42 cases. The most common symptom in our group was dribbling poor stream 51% and urinary tract infection (UTI 40.8%. There was vesico-ureteral-reflux (VUR in 61.2%, and hydronephrosis in 82.6%. Most common associated anomaly was kidney anomalies (multicystic kidney disease and renal agenesis/dysplasia in 8 (8.2% patients. Twenty patients had prenatal diagnosis of PUV. Complication occurred in three (3.1% patients. Mortality occurred in 5 (5.1% patients. Mean follow-up period was 3.4±1.2 years (1.5 months to 5 years.Conclusion: Urinary drainage by feeding tube in early days of infancy, followed by valve ablation is the best treatment in PUV, and urinary diversion improves the outcome. VCUG is still the gold-standard imaging modality for documenting PUVs. The factors like renal dysplasia and UTI have their role in final outcome.

  16. AUTOMATION OF BUISNESS-PROCESSES OF A TRAINING CENTER

    Kovalenko A. V.

    2015-06-01

    Full Text Available The modern Russian companies have realized the need of automation of document flow not only as a mean of keeping documents in order, but also as a tool of optimization of expenses, as an assistant in adoption of administrative decisions. The Russian market of information systems for long time had no software products intended for educational institutions. The majority of the automated systems are intended for the enterprises with an activity in the sphere of trade and production. In comparison with the above companies, the list of software products for commercial training centers is small. Even considering the developed line of programs it is impossible to speak about meeting all the requirements for companies of such activity. At creation of the automated system for training center, the analysis of the existing software products intended for automation of training centers and adjacent institutes was carried out; a number of features of activity are revealed. The article is devoted to the description of the developed automated information system of document flow of a commercial educational institution, namely the developed configuration of "Training center" on a platform of "1C: Enterprise 8.2". The developed program complex serving as the administrative tool for the analysis of economic activity of training center, scheduling of the educational equipment and teaching structure, payroll calculation taking into account specifics of branch has been presented in the article

  17. Integrating Automation into a Multi-Mission Operations Center

    Surka, Derek M.; Jones, Lori; Crouse, Patrick; Cary, Everett A, Jr.; Esposito, Timothy C.

    2007-01-01

    NASA Goddard Space Flight Center's Space Science Mission Operations (SSMO) Project is currently tackling the challenge of minimizing ground operations costs for multiple satellites that have surpassed their prime mission phase and are well into extended mission. These missions are being reengineered into a multi-mission operations center built around modern information technologies and a common ground system infrastructure. The effort began with the integration of four SMEX missions into a similar architecture that provides command and control capabilities and demonstrates fleet automation and control concepts as a pathfinder for additional mission integrations. The reengineered ground system, called the Multi-Mission Operations Center (MMOC), is now undergoing a transformation to support other SSMO missions, which include SOHO, Wind, and ACE. This paper presents the automation principles and lessons learned to date for integrating automation into an existing operations environment for multiple satellites.

  18. A center vortex representaton of the classical SU(2) vacuum

    Olesen, P

    2016-01-01

    The classical massless SU(2) field theory has an infinite number of gauge equivalent representations of the vacuum. We show that among these there exists a center vortex representation with some similarity to the quantum vacuum of the same theory. This classical perturbative SU(2) vacuum consists of a lattice of center vortex pairs combining to triviality. However, this triviality is broken by perturbations, for example by adding a mass term, or by considering the electroweak theory where the Higgs field does the breaking, or by quantum fluctuations like in QCD.

  20. A radio search for planetary nebulae near the galactic center

    Because of galactic center is a hostile environment, and because planetaries are weak radio emitters, it is not clear a priori that one expects to detect any planetary nebulae at all in the nuclear region of the Galaxy. Therefore the expected lifetime and flux density distribution of galactic center nebulae is considered. The principal observational results from the Westerbork data, and the results of some pilot observations with the Very Large Array, which were intended to distinguish planetaries from other radio sources on an individual basis are given.

    2003-01-01

    Winds from massive stars supply ~ 10^{-3} solar masss/year of gas to the central parsec of the Galactic Center. Spherically symmetric hydrodynamic calculations show that ~ 1 % of this gas, or ~ 10^{-5} solar masses/year, flows in towards the central massive black hole Sgr A*; the remaining gas, ~ 10^{-3} solar masses/year, is thermally driven out of the central star cluster in a wind. This dynamical model accounts for the level of diffuse X-ray emission observed in the Galactic Center by Chan...

  3. Electric power transmission for a Hanford Nuclear Energy Center (HNEC)

    A study of nuclear energy centers was conducted by the Atomic Energy Commission and reported in WASH 1288, Evaluation of Nuclear Energy Centers, January 1974. The portion of the study covering a Hanford Nuclear Energy Center (HNEC) was conducted by Battelle-Northwest, and a preliminary study of transmission of HNEC power was prepared with the assistance of the Bonneville Power Administration (BPA). In 1975 the Energy Research and Development Administration (ERDA) requested a more detailed study of the HNEC, one aspect of which focuses on the transmission system. The transmission system was developed through a series of technical discussions with BPA personnel responsible for transmission system planning. The purpose of the discussions is to further develop a concept of a system which will transmit power from HNEC to markets in the Pacific Northwest, and to compare it with a system to serve the same loads from dispersed generating capacity; the major portion of the dispersed capacity would be in the general vicinity of load centers. The latter alternative would follow conventional siting practice and is referred to as a distributed (DIST) 100% system or case for 1998, and (DIST) 150% case for 2002. The planning of a power transmission system is an iterative process developed over a considerable time period. The report is an initial iteration, and substantial further studies will be required to firm up a transmission system from an HNEC, should such a generation expansion develop. Some of the required additional studies are presented in the last section of the report

  4. Medicine as a corporate enterprise, patient welfare centered profession, or patient welfare centered professional enterprise?

    Ajai R. Singh

    2005-11-01

    become a corporate enterprise or remain a patient welfare centered profession. A third approach involves an eclectic resolution of the two. Such amount of patient welfare as also ensures profit, and such amount of profit as also ensures patient welfare is to be forwarded. For, profit, without patient welfare, is blind. And patient welfare, without profit, is lame. According to this approach, medicine becomes a patient welfare centered professional enterprise. The various ramifications of each of these approaches are discussed in this monograph.

  7. Developing a center for Hispanic youth violence prevention.

    Mirabal-Colón, Brenda

    2003-03-01

    Youth violence is a serious public health problem, described by the Surgeon General's Report on Youth Violence (2001). Homicide is the second cause of death for the 15-24 age population in the USA and Puerto Rico; intentional injuries also result in significant morbidity. Youth are at greater risk of being victims than perpetrators of violence. African American and Hispanic youth are at particular risk. Effective, community-based initiatives to prevent youth violence are necessary to interrupt the cycle of violence. In 2000, the Centers for Disease Control and Prevention of the Department of Health and Human Services awarded grants to establish ten Academic Centers of Excellence for Youth Violence Prevention. This article describes the development of the Center for Hispanic Youth Violence Prevention, of the FILIUS Institute of the University of Puerto Rico. PMID:12733449

    Full Text Available Although photoluminescence from gallium-arsenide (GaAs deep-centers was first observed in the 1960s, semiconductor lasers have always utilized conduction-to-valence-band transitions. Here we review recent materials studies leading to the first GaAs deep-center laser. First, we summarize well-known properties: nature of deep-center complexes, Franck-Condon effect, hotoluminescence. Second, we describe our recent work: insensitivity of photoluminescence with heating, striking differences between electroluminescence and photoluminescence, correlation between transitions to deep-states and absence of bandgap-emission. Room-temperature stimulated-emission from GaAs deep-centers was observed at low electrical injection, and could be tuned from the bandgap to half-the-bandgap (900–1,600 nm by changing the electrical injection. The first GaAs deep-center laser was demonstrated with electrical injection, and exhibited a threshold of less than 27 mA/cm2 in continuous-wave mode at room temperature at the important 1.54 μm fiber-optic wavelength. This small injection for laser action was explained by fast depopulation of the lower state of the optical transition (fast capture of free holes onto deep-centers, which maintains the population inversion. The evidence for laser action included: superlinear L-I curve, quasi-Fermi level separations satisfying Bernard-Duraffourg’s criterion, optical gains larger than known significant losses, clamping of the optical-emission from lossy modes unable to reach laser action, pinning of the population distribution during laser action.

    We develop a web-based database system for electron paramagnetic resonance (EPR) centers in semiconductors. This database is available to anyone at http://www.kc.tsukuba.ac.jp/div-media/epr/. It currently has more than 300 records of the spin-Hamiltonian parameters for major known EPR centers. One can upload own new records to the database or can use simulation tools powered by EPR-NMR(C). Here, we describe the features and objectives of this database, and mention some future plans.

  10. Fluor Hanford ALARA Center is a D and D Resource

    The mission at the Hanford Nuclear Reservation changed when the last reactor plant was shut down in 1989 and work was started to place all the facilities in a safe condition and begin decontamination, deactivation, decommissioning, and demolition (D and D). These facilities consisted of old shutdown reactor plants, spent fuel pools, processing facilities, and 177 underground tanks containing 53 million gallons of highly radioactive and toxic liquids and sludge. New skills were needed by the workforce to accomplish this mission. By 1995, workers were in the process of getting the facilities in a safe condition and it became obvious improvements were needed in their tools, equipment and work practices. The Hanford ALARA Program looked good on paper, but did little to help contractors that were working in the field. The Radiological Control Director decided that the ALARA program needed to be upgraded and a significant improvement could be made if workers had a place they could visit that had samples of the latest technology and could talk to experienced personnel who have had success doing D and D work. Two senior health physics personnel who had many years experience in doing radiological work were chosen to obtain tools and equipment from vendors and find a location centrally located on the Hanford site. Vendors were asked to loan their latest tools and equipment for display. Most vendors responded and the Hanford ALARA Center of Technology opened on October 1, 1996. Today, the ALARA Center includes a classroom for conducting training and a mockup area with gloveboxes. Two large rooms have a containment tent, several glove bags, samples of fixatives/expandable foam, coating displays, protective clothing, heat stress technology, cutting tools, HEPA filtered vacuums, ventilation units, pumps, hydraulic wrenches, communications equipment, shears, nibblers, shrouded tooling, and several examples of innovative tools developed by the Hanford facilities.

    Full Text Available Eitan S Burstein, Douglas R LazzaroDepartments of Ophthalmology, SUNY Downstate Medical Center and Kings County Hospital Center, Brooklyn, NY, USABackground: The purpose of this study was to examine patient characteristics and outcomes in a group of consecutive patients with ruptured globe eye injuries at Kings County Hospital Center, a large, urban, level 1 trauma center.Methods: A retrospective chart review was performed to identify all patients with ruptured globe eye injuries seen between January 2009 and October 2011. Thirty-eight patients who sustained ruptured globe eye injuries from all causes were investigated for etiology and final visual outcomesResults: Eight eyes in which vision could be assessed were evaluated as having no light perception at presentation and three of these eyes required primary enucleation. Of the 38 eyes, orbit fractures were found in 15 eyes and an intraocular foreign body was found in six eyes.Discussion: Our cohort revealed a 37.5% rate of primary enucleation in eyes with no light perception, which we believe to be a reflection of the severity of injury. All three cases were secondary to a gunshot wound. Further, our sample, although small in size, revealed a very high percentage of eyes that were ruptured secondary to violent causes compared with other studies.Keywords: rupture, trauma, violence, urban, epidemiology, emergency, globe

  20. A Distributed Weighted Voting Approach for Accurate Eye Center Estimation

    Gagandeep Singh

    2013-05-01

    Full Text Available This paper proposes a novel approach for accurate estimation of eye center in face images. A distributed voting based approach in which every pixel votes is adopted for potential eye center candidates. The votes are distributed over a subset of pixels which lie in a direction which is opposite to gradient direction and the weightage of votes is distributed according to a novel mechanism.  First, image is normalized to eliminate illumination variations and its edge map is generated using Canny edge detector. Distributed voting is applied on the edge image to generate different eye center candidates. Morphological closing and local maxima search are used to reduce the number of candidates. A classifier based on spatial and intensity information is used to choose the correct candidates for the locations of eye center. The proposed approach was tested on BioID face database and resulted in better Iris detection rate than the state-of-the-art. The proposed approach is robust against illumination variation, small pose variations, presence of eye glasses and partial occlusion of eyes.Defence Science Journal, 2013, 63(3, pp.292-297, DOI:http://dx.doi.org/10.14429/dsj.63.2763

  1. Off-Center D- Centers in a Quantum Dot in the Presence of a Perpendicular Magnetic Fields

    XIE Wen-Fang

    2001-01-01

    We investigate the effect of the position of the donor in quantum dots on the energy spectrum in the presence ofa perpendicular magnetic field by using the method of few-body physics. As a function of the magnetic field, we find, when D- centers are placed sufficiently off-center, discontinuous ground-state transitions which are similar to those found in many-electron parabolic quantum dots. Series of magic numbers of angular momentum which minimize the ground-state electron-electron interaction energy have been discovered. The dependence of the binding energy of the ground-state of the 1D- center on the dot radius for a few values of the magnetic field strength is obtained and compared with other results.

  3. "Out in the Rural: A Health Center in Mississippi"

    Carolyn Chu

    2006-08-01

    Full Text Available Prior to the 1960s, most health care in the United States had been delivered privately to those who could afford it or administered via church-based “charity” systems to those who could not. When President Lyndon B. Johnson and the federal government declared a “war on poverty” via the Economic Opportunity Act of 1964, medical and civil rights activists seized the opportunity to create public health systems that could reduce disparities in wealth and health. At the time H. Jack Geiger was a young doctor working at Tufts University. As a medical student, Dr. Geiger had studied the principles of Community Oriented Primary Care with Sidney Kark and colleagues in rural Natal, South Africa. [See page 116 of this issue] Along with the residents of North Bolivar County, Mississippi, Dr. Geiger worked to establish a center that would combine local resources with federal funds to empower this economically devastated community of the Mississippi Delta. By establishing a network of aggressive outreach and education efforts, and developing multiple health employment opportunities, the Delta Health Center and its participants became an engine for social reform. The Community Health Center model was adopted widely by the federal government and today is administered by the Bureau of Primary Care (http://bphc.hrsa.gov/. Dr. Geiger is currently a Professor Emeritus at the Department of Community Health and Social Medicine at the Sophie Davis School of Biomedical Education at City College in New York City. The film Shot in the fall of 1969 and the winter of 1970, “Out in the Rural: A Health Center in Mississippi” highlights one of the very first Community Health Centers in the United States: the Tufts-Delta Health Center of North Bolivar County, Mississippi. The film captures the broad vision of a community health center involved in far more than traditional medical diagnosis and treatment. Credits Music: The Locust Grove Choir and The Shelby Male

    2010-09-01

    Full Text Available Objective: To analyze the work process of mental health professionals from a Psychosocial Attention Center (CAPS, from the knowledge and the practices applied in the production of care and its interface with user’s demands and the service offering. Methods: A case study with qualitative approach. Twenty-eight subjects joined in and were divided into three groups: I (eleven mental health workers, II (eleven users e III (six family members. The semistructured interview was used besides systematic observation, in the search for data about the work process of the professionals of the Psychosocial Attention Center, the relationship between team and user, offering and demand, access, technologies of care, knowledge and practices and interdisciplinarity. The investigation was based upon critical content analysis and was oriented by the flowchart analyzer. Results: The service organization and its work process are directed to the immediate supply of the population’s demands, which depicts a care based on prescriptive practices. Thus, the flow of assistance and the service offering complement each other in the need of a procedure and in its exhaustive offering by the service, dissolving interdisciplinary conductions of intervention shared with the user.Conclusion: Mental health care is still surrounded by biomedical hegemony centered in procedures directed to pharmacological prescription. Despite this reality, the work centered on the user and the utilization of soft technologies – communication, link, welcoming – begin to take part of the daily CAPS service offering, although it is only present in specific activities of certain procedures.

  9. A knowledge-centered paradigm for operations and design

    A paradigm premised on the reactor design basis and on its systems, structures, and components also governs nuclear power plant operations. This machine-centered paradigm emphasizes a functional and discipline-based division of responsibilities, which can create hierarchical 'silos' and 'stovepipes' inhibiting the development and lateral exchange of knowledge about safety-critical system interactions. A knowledge-centered paradigm instead encourages the timely development, analysis, and exchange of information about system conditions and their likely consequences. This new paradigm puts operational focus on the importance of operating experience, informative root cause analyses, effective corrective actions, and cross-discipline exchange and cooperation. Although the knowledge-centered paradigm is already central to three main strategies of risk reduction, it is less likely to be recognized as such in terms of priorities, resources, and training: configuration control, control room operations, and root cause analysis. To maintain the capacity for safe shutdown and to preserve public trust, the knowledge-centered paradigm places as high a priority on interactions of safety-critical knowledge as it does on interactions of safety-critical systems, structures, and components.

  12. A simulation approach to a virtual base defense operating center

    Athmer, Keith; Gaughan, Chris

    2010-04-01

    The TRADOC Maneuver Support Center of Excellence (MSCoE) is the Army proponent for protection and in turn, has the mission to support fixed site protection issues. To this end, the Maneuver Support Battle Lab (MSBL) developed a Virtual Base Defense Operating Center (VBDOC) capability that was initiated in support of the Force Protection Joint Experiment (FPJE) to examine data fusion enhancements and improvements to the Common Operating Picture (COP) display. Furthermore BDOC Standard Operating Procedures (SOPs), Tactics, Techniques and Procedures (TTPs), and Unmanned Ground Vehicle (UGV) capabilities were examined in order to optimize manpower, reduce exposure of friendly personnel, and improve force protection. The Modeling and Simulation (M&S) architecture was especially important due to the cost of providing realistic environments, such as Chemical Biological Radiological Nuclear (CBRN) hazards, and the availability of soldiers for experimentation. The VBDOC simulation architecture contains a force-on-force simulation, a CBRN simulation, a desktop UGV Advanced Concepts Research Tool (ACRT) and a sensor controller using the Distributed Interactive Simulation (DIS) protocol. This simulation architecture stimulated actual Command and Control (C2) systems including the Joint Battlespace Command and Control System (JBC2S) and the Joint Warning and Reporting Network (JWARN). These C2 systems, along with video feeds from various sensors and unmanned vehicles, were used by Battle Captains and staffs for situational awareness of the battlefield while conducting the experiment. The VBDOC capability offers a controlled environment to study fixed site protection issues, such as future Concept of Operation (CONOP)/TTP/SOP development and refinement, examining emerging concepts, and assessing specific technology capabilities.

  13. Building a High Performance Computing Infrastructure for Novosibirsk Scientific Center

    Novosibirsk Scientific Center (NSC), also known worldwide as Akademgorodok, is one of the largest Russian scientific centers hosting Novosibirsk State University (NSU) and more than 35 research organizations of the Siberian Branch of Russian Academy of Sciences including Budker Institute of Nuclear Physics (BINP), Institute of Computational Technologies (ICT), and Institute of Computational Mathematics and Mathematical Geophysics (ICM and MG). Since each institute has specific requirements on the architecture of the computing farms involved in its research field, currently we've got several computing facilities hosted by NSC institutes, each optimized for the particular set of tasks, of which the largest are the NSU Supercomputer Center, Siberian Supercomputer Center (ICM and MG), and a Grid Computing Facility of BINP. Recently a dedicated optical network with the initial bandwidth of 10 Gbps connecting these three facilities was built in order to make it possible to share the computing resources among the research communities of participating institutes, thus providing a common platform for building the computing infrastructure for various scientific projects. Unification of the computing infrastructure is achieved by extensive use of virtualization technologies based on XEN and KVM platforms. The solution implemented was tested thoroughly within the computing environment of KEDR detector experiment which is being carried out at BINP, and foreseen to be applied to the use cases of other HEP experiments in the upcoming future.

  19. A Center for Mideast Oceanographic Data in Muscat, Oman

    Ingle, S.; Belabbassi, L.; Du Vall, K.; Wang, Z.

    2012-12-01

    Lighthouse designed and installed a real-time cabled ocean observing system off the northern coast of the Sultanate of Oman in 2005 and a second system, farther to the south, existed as autonomous moorings from 2005-2009 and was upgraded to a real-time cabled system in early 2010. Since 2005 Lighthouse has operated and maintained those systems to produce a wealth of data on a poorly understood region of the global oceans. The systems record data hourly on current velocities over a range of depths, and temperature, pressure, conductivity, dissolved oxygen and turbidity at the depth of the sensor; the northern system also collects seismic and bottom pressure (tsunami detection) information continuously. Processing codes for all data have been developed and honed over the years in cooperation with oceanographers from Texas A&M University. As a joint and complementary effort, ocean circulation and tsunami impact models have been developed for the regional waters near Oman. In Oman, our work is coordinated through the Ministry of Agriculture and Fisheries Wealth. From the beginning, Lighthouse has intended to transition data processing and analysis over to the Sultanate. To facilitate this transition, we propose to establish a Center for Mideast Oceanographic Data located in Muscat, Oman that may also serve as a regional oceanographic data depository and research center. Main activities to be carried out include: marine data processing and management, training of Omani professionals in data processing and analysis, facilitating regional and international collaboration by hosting workshops or short courses, and employing the models for research purposes. The center would work with the newly-established Hazard Monitoring Center to develop modeled now- and forecast products for marine operations and safety. The goal is to house, in a single location, datasets and models that will help Oman manage and maintain its marine environment and resources for generations to come.

    Malone, Eileen B; Kirchbdoerfer, Richard G; Wolford-Connors, Ann

    2005-01-01

    The Army Medical Department (AMEDD), a comprehensive worldwide integrated healthcare system with an annual budget of more than $6 billion, more than 50,000 employees, and 2.4 million beneficiaries, developed and implemented a comprehensive patient-centered enterprise-wide information management and information technology strategy to facilitate information management systems and infrastructure decisions by leaders. This article describes a patient-centered model used to organize and link healthcare activities and activity leaders to portray patient care, administrative, business, financial, supply, and strategic support information systems. Activity and IT leaders applied a refined strategic alignment model to identify specific clinical, business, and IT goals and to detail the necessary infrastructure investments using a systems view. The use of patient and process outcome measures tied to the AMEDD's Balanced Score Card' helped leaders to manage IT strategy execution. Now, two years into the effort, a sample activity strategy--outpatient care--is used to illustrate the application of these tools to the development and implementation of a patient-centered IT strategy.

  6. Mining of Business-Oriented Conversations at a Call Center

    Takeuchi, Hironori; Nasukawa, Tetsuya; Watanabe, Hideo

    Recently it has become feasible to transcribe textual records from telephone conversations at call centers by using automatic speech recognition. In this research, we extended a text mining system for call summary records and constructed a conversation mining system for the business-oriented conversations at the call center. To acquire useful business insights from the conversational data through the text mining system, it is critical to identify appropriate textual segments and expressions as the viewpoints to focus on. In the analysis of call summary data using a text mining system, some experts defined the viewpoints for the analysis by looking at some sample records and by preparing the dictionaries based on frequent keywords in the sample dataset. However with conversations it is difficult to identify such viewpoints manually and in advance because the target data consists of complete transcripts that are often lengthy and redundant. In this research, we defined a model of the business-oriented conversations and proposed a mining method to identify segments that have impacts on the outcomes of the conversations and can then extract useful expressions in each of these identified segments. In the experiment, we processed the real datasets from a car rental service center and constructed a mining system. With this system, we show the effectiveness of the method based on the defined conversation model.

  7. A minimum attention control center for nuclear power plants

    Control Centers for Nuclear Power Plants have characteristically been designed for maximum attention by the operating staffs of these plants. Consequently, the monitoring, control and diagnostics oriented cognitive activities by these staffs, were mostly ''data-driven'' in nature. This paper addresses a control center concept, under development by Combustion Engineering, that promotes a more ''information-driven'' cognitive interaction process between the operator and the plant. The more ''intelligent'' and therefore less attentive nature of such interactive process utilizes computer implemented cognitive engineered algorithms. The underlying structure of these algorithms is based upon the Critical Function/Success Path monitoring principle. The paper highlights a typical implementation of the minimum attention concept for the handling of unfamiliar safety related events. (author)

    2008-01-01

    Shared decision making (SDM) is regarded as an ideal in chronic illness care but is difficult to implement in practice. Communication and reflection play an important role and need further investigation. Using grounded theory, we studied patient-provider interaction in a difficult and advanced area......: managing poorly controlled diabetes. A person-centered communication and reflection model was developed, identifying SDM in chronic care to be a question of professionals gaining insight into patients' decisions, rather than the opposite. The model reveals important choices in communication and reflection......, which were decisive for whether SDM was achieved or not. SDM involved co-creating person-centered knowledge: concrete evidence which empowered patients and professionals in problem solving. Although further testing is required, the general tenets of the model are expected to be applicable across chronic...

  9. Agriculture and biotechnology centers of the PAEC: a resume

    Pakistan recognized the role of nuclear techniques in agricultural and other biological research and started establishing goal-oriented, multi- disciplinary institutions to help agricultural research in the country. A core manpower was trained and centers established in the cities where most of the agricultural research was located; the objective was to supplement the research activity in areas where nuclear techniques would have a clear advantage. The first centre was established at Tandojam, Sindh and others at Faisalabad, Mymensingh, Peshawar and again at Faisalabad. Apart from agricultural research, these centers utilized their facilities and ventured into other areas such as biotechnology and can now take some pride in contributing in the country's economy and in development of human resource and helping develop a science culture in the country. With better management systems, the inputs seem to have been better utilized. That the end users and the government have recognized the contributions of these centers is evident from the number of farmers visiting these institutions for advice and the number of medals awarded to their scientists by the government. These institutes could, perhaps, have done even better yet it seems their positive contributions outweigh their deficiencies. In this piece of writing a brief history of these institutions is given and some information provided about the raison for their programmes and the environment under which the programmes were executed. A few of their salient achievements have also been mentioned. (author)

  10. Touch-Trigger Probe Error Compensation in a Machining Center

    Kinematic contact trigger probes are widely used for feature inspection and measurement on coordinate measurement machines (CMMs) and computer numerically controlled (CNC) machine tools. Recently, the probing accuracy has become one of the most important factors in the improvement of product quality, as the accuracy of such machining centers and measuring machines is increasing. Although high-accuracy probes using strain gauge can achieve this requirement, in this paper we study the universal economic kinematic contact probe to prove its probing mechanism and errors, and to try to make the best use of its performance. Stylus-ball-radius and center-alignment errors are proved, and the probing error mechanism on the 3D measuring coordinate is analyzed using numerical expressions. Macro algorithms are developed for the compensation of these errors, and actual tests and verifications are performed with a kinematic contact trigger probe and reference sphere on a CNC machine tool

  11. The users centered design of a new digital fluorometer

    The fluorometer is an equipment used in chemical analysis laboratories, research institutes and nuclear fuel cycle companies. This equipment measures an unknown amount of uranium in ores, rivers, etc. The fluorometer functioning is based on the uranium fluorescence when submitted to the ultraviolet radiation incidence. The fluorescence is measured by an electronic optic system with optics filters, photomultiplier tube, and a current amplifier. The user centered design involves the user in the product development in all phases of the design process. Users are not simply consulted at the beginning of the design process and evaluated the system at the end; they are treated as partners throughout the design process. The user centered design emphasizes the needs and abilities of the users and improves the usability of the equipment. The activity centered design emphasizes the development of the equipment with a deep understanding of the users activities and of the current work practices of the users. The aim of this paper is to present a methodological framework that contributes to the design and evaluation of a new digital fluorometer towards an approach related to the users and their activities. This methodological framework includes users-based testing, interviews, questionnaires, human factors standards and guidelines, the users activity analysis and users satisfaction questionnaire.

  13. Reliability of generation at a Hanford Nuclear Energy Center (HNEC)

    A nuclear energy center characteristically would have large amounts of electric generating capacity in a relatively small geographical area. HNEC is a conceptual nuclear energy center containing 20 generating units of 1200 MW capacity each, located at Hanford, Washington. DS is an alternative concept; namely, 20 generating units of similar capacity in six clusters at sites along the Columbia and Willamette rivers in Washington and Oregon. HNEC in year 2005 could provide up to 30% of system capacity; typically utilities limit concentration of thermal plant generation to about 15% of system requirements. For this reason it is appropriate to examine the reliability of generation at a nuclear energy center to determine if it could be less than at dispersed sites because of local conditions and the close proximity of many generating units. In the report, reliability of generation HNEC is assessed by comparing it with that at Dispersed Sites (DS) throughout the Pacific Northwest. Reliability is measured in terms of two sets of risks: risk of forced outage, and risk of user power shortage

  16. A center's experience: pulmonary function in spinal cord injury.

    Schilero, Gregory J; Radulovic, Miroslav; Wecht, Jill M; Spungen, Ann M; Bauman, William A; Lesser, Marvin

    2014-06-01

    Traumatic spinal cord injury (SCI) is associated with significant psychological and physical challenges. A multidisciplinary approach to management is essential to ensure recovery during the acute phase, and comprehensive rehabilitative strategies are necessary to foster independence and quality of life throughout the chronic phase of injury. Complications that beset these individuals are often a unique consequence of SCI, and knowledge of the effects of SCI upon organ systems is essential for appropriate management. According to the National SCI Statistical Center (NSCISC), as of 2010 there were an estimated 265,000 persons living with SCI in the United States, with approximately 12,000 incidence cases annually. Although life expectancy for newly injured individuals with SCI is markedly reduced, persons with chronic SCI are expected to live about as long as individuals without SCI; however, longevity varies inversely with level of injury. Since 2005, 56 % of persons with SCI are tetraplegic, and due to paralysis of respiratory muscles, these individuals may be especially prone to pulmonary complications, which remain a major cause of mortality among persons with chronic SCI. We at the VA Rehabilitation Research and Development Center of Excellence for the Medical Consequences of SCI at the James J. Peters VA Medical Center have devoted more than 25 years to the study of secondary medical conditions that complicate SCI. Herein, we review pulmonary research at the Center, both our past and future endeavors, which form an integral part of our multidisciplinary approach toward achieving a greater understanding of and improving care for veterans with SCI.

    Most tasks that are desirable to train in a virtual environment are not tasks that we do alone, but rather are executed collaboratively with one or more team members. Yet little is known about how to construct virtual environment training systems that support collaborative behavior. The purpose of this thesis was to explore methodologies for developing collaborative virtual environments for training. Our approach centered on analyzing task or training specific requirements for the simulation ...

  18. Cultivating Data Expertise and Roles at a National Research Center

    Thompson, C. A.

    2015-12-01

    As research becomes more computation and data-intensive, it brings new demands for staff that can manage complex data, design user services, and facilitate open access. Responding to these new demands, universities and research institutions are developing data services to support their scientists and scholarly communities. As more organizations extend their operations to research data, a better understanding of the staff roles and expertise required to support data-intensive research services is needed. What is data expertise - knowledge, skills, and roles? This study addresses this question through a case study of an exemplar research center, the National Center for Atmospheric Research (NCAR) in Boulder, CO. The NCAR case study results were supplemented and validated with a set of interviews of managers at additional geoscience data centers. To date, 11 interviews with NCAR staff and 19 interviews with managers at supplementary data centers have been completed. Selected preliminary results from the qualitative analysis will be reported in the poster: Data professionals have cultivated expertise in areas such as managing scientific data and products, understanding use and users, harnessing technology for data solutions, and standardizing metadata and data sets. Staff roles and responsibilities have evolved over the years to create new roles for data scientists, data managers/curators, data engineers, and senior managers of data teams, embedding data expertise into each NCAR lab. Explicit career paths and ladders for data professionals are limited but starting to emerge. NCAR has supported organization-wide efforts for data management, leveraging knowledge and best practices across all the labs and their staff. Based on preliminary results, NCAR provides a model for how organizations can build expertise and roles into their data service models. Data collection for this study is ongoing. The author anticipates that the results will help answer questions on what are

  19. Building diversity in a complex academic health center.

    South-Paul, Jeannette E; Roth, Loren; Davis, Paula K; Chen, Terence; Roman, Anna; Murrell, Audrey; Pettigrew, Chenits; Castleberry-Singleton, Candi; Schuman, Joel

    For 30 years, the many diversity-related health sciences programs targeting the University of Pittsburgh undergraduate campus, school of medicine, schools of the health sciences, clinical practice plan, and medical center were run independently and remained separate within the academic health center (AHC). This lack of coordination hampered their overall effectiveness in promoting diversity and inclusion. In 2007, a group of faculty and administrators from the university and the medical center recognized the need to improve institutional diversity and to better address local health disparities. In this article, the authors describe the process of linking the efforts of these institutions in a way that would be successful locally and applicable to other academic environments. First, they engaged an independent consultant to conduct a study of the AHC's diversity climate, interviewing current and former faculty and trainees to define the problem and identify areas for improvement. Next, they created the Physician Inclusion Council to address the findings of this study and to coordinate future efforts with institutional leaders. Finally, they formed four working committees to address (1) communications and outreach, (2) cultural competency, (3) recruitment, and (4) mentoring and retention. These committees oversaw the strategic development and implementation of all diversity and inclusion efforts. Together these steps led to structural changes within the AHC and the improved allocation of resources that have positioned the University of Pittsburgh to achieve not only diversity but also inclusion and to continue to address the health disparities in the Pittsburgh community.

  2. Implementation of a virtual link between power system testbeds at Marshall Spaceflight Center and Lewis Research Center

    Doreswamy, Rajiv

    1990-01-01

    The Marshall Space Flight Center (MSFC) owns and operates a space station module power management and distribution (SSM-PMAD) testbed. This system, managed by expert systems, is used to analyze and develop power system automation techniques for Space Station Freedom. The Lewis Research Center (LeRC), Cleveland, Ohio, has developed and implemented a space station electrical power system (EPS) testbed. This system and its power management controller are representative of the overall Space Station Freedom power system. A virtual link is being implemented between the testbeds at MSFC and LeRC. This link would enable configuration of SSM-PMAD as a load center for the EPS testbed at LeRC. This connection will add to the versatility of both systems, and provide an environment of enhanced realism for operation of both testbeds.

  3. Job center

    To better meet the needs of AGU members, a program has been started to increase the effectiveness of the Job Center activity at the Spring and Fall Meetings. As a result, participation in the Job Center at the 1988 AGU Spring Meeting in Baltimore increased substantially compared to previous Spring Meetings. The number of employers, applicants, and interviews scheduled more than doubled compared to the 1987 Spring Job Center.In order to make the meeting Job Centers even better, a survey is being conducted of employers and applicants who participated in the 1988 Spring Job Center. Evaluation of this survey will be useful in continuing increased participation in and the effectiveness of the Job Center at the 1988 Fall Meeting. Past participants and those interested in the future of the Job Center are encouraged to forward comments and suggestions to AGU, Member Programs Division, 2000 Florida Ave., N.W., Washington, DC 20009.

  4. Wings: A New Paradigm in Human-Centered Design

    Schutte, Paul C.

    1997-01-01

    Many aircraft accidents/incidents investigations cite crew error as a causal factor (Boeing Commercial Airplane Group 1996). Human factors experts suggest that crew error has many underlying causes and should be the start of an accident investigation and not the end. One of those causes, the flight deck design, is correctable. If a flight deck design does not accommodate the human's unique abilities and deficits, crew error may simply be the manifestation of this mismatch. Pilots repeatedly report that they are "behind the aircraft" , i.e., they do not know what the automated aircraft is doing or how the aircraft is doing it until after the fact. Billings (1991) promotes the concept of "human-centered automation"; calling on designers to allocate appropriate control and information to the human. However, there is much ambiguity regarding what it mean's to be human-centered. What often are labeled as "human-centered designs" are actually designs where a human factors expert has been involved in the design process or designs where tests have shown that humans can operate them. While such designs may be excellent, they do not represent designs that are systematically produced according to some set of prescribed methods and procedures. This paper describes a design concept, called Wings, that offers a clearer definition for human-centered design. This new design concept is radically different from current design processes in that the design begins with the human and uses the human body as a metaphor for designing the aircraft. This is not because the human is the most important part of the aircraft (certainly the aircraft would be useless without lift and thrust), but because he is the least understood, the least programmable, and one of the more critical elements. The Wings design concept has three properties: a reversal in the design process, from aerodynamics-, structures-, and propulsion-centered to truly human-centered; a design metaphor that guides function

  5. A Proposed Approach for Prioritizing Maintenance at NASA Centers

    Dunn, Steven C.; Sawyer, Melvin H.

    2013-01-01

    The National Aeronautics and Space Administration (NASA) manages a vast array of infrastructure assets across ten National Centers with a worth of at least 30 billion dollars. Eighty percent of this infrastructure is greater than 40 years old and is in degraded condition. Maintenance budgets are typically less than one percent of current replacement value (CRV), much less than the 2-4% recommended by the National Research Council. The maintenance backlog was 2.55 billion dollars in FY10 and growing. NASA s annual budgets have flattened and are at risk of being reduced, so the problem is becoming even more difficult. NASA Centers utilize various means to prioritize and accomplish maintenance within available budgets, though data is suspect and processes are variable. This paper offers a structured means to prioritize maintenance based on mission criticality and facility performance (ability of the facility to deliver on its purpose). Mission alignment is assessed using the current timeframe Mission Dependence Index and a measure of facility alignment with the 2011 NASA Strategic Plan for the long-term perspective. Facility performance is assessed by combining specific findings from a structured facility condition assessment and an assessment of actual functional output. These are then combined in a matrix to identify the facilities most critical to mission and able to deliver services. The purpose of this approach is to provide the best benefits for the available funding. Additionally, this rationale can also be applied to the prioritization of investment (recapitalization) projects so that the ultimate customers of this paper, the senior infrastructure managers at each NASA Center, are better able to strategically manage their capabilities.

  6. A Study on Self Centering of Face Bows

    Hanau spring bow has been in use since 1986. Hanau spring bow is claimed to maintain self centering property when it is positioned in the patient as well as in the articulator. However there is no documented evidence to prove that feature. Mainly it was due to the absence of a testing device. Exclusively for the present study, the testing device consisting of a platform, stops and distance measuring system was designed by the third author. This study proved that Hanau has the capability of se...

  7. Phosphorus vacancy in InP: A negative- U center

    Alatalo, M.; Nieminen, Risto M.; Puska, Martti J.; Seitsonen, A. P.; Virkkunen, R.

    1993-01-01

    Using first-principles simulations, we identify the phosphorous vacancy in InP as a negative-U center. The deep levels associated with this defect are in the upper half of the band gap, and the charge state changes directly from positive to negative as the Fermi level is raised: the vacancy captures two electrons rather than one. We also obtain the relaxed structures and formation energies for the In and P vacancies as a function of both electron and atomic chemical potentials. Peer reviewed

    Redmond, I. R.; Linke, R. A.; Chuang, E.; Psaltis, D.

    1997-01-01

    We report on the optical storage of digital data in a semiconductor sample containing DX centers. The diffraction efficiency and the bit-error-rate performance of multiplexed data images are shown to agree well with a simple model of the material. Uniform storage without an exposure schedule is demonstrated. The volume sensitivity is found to be ~10^3 times that of LiNBO3:Fe. The importance of coherent addition of scattered light with diffracted light in holographic data storage is discussed.

  10. A phenomenological investigation of science center exhibition developers' expertise development

    Young, Denise L.

    The purpose of this study was to examine the exhibition developer role in the context of United States (U.S.) science centers, and more specifically, to investigate the way science center exhibition developers build their professional expertise. This research investigated how successfully practicing exhibition developers described their current practices, how they learned to be exhibition developers, and what factors were the most important to the developers in building their professional expertise. Qualitative data was gathered from 10 currently practicing exhibition developers from three science centers: the Exploratorium, San Francisco, California; the Field Museum, Chicago, Illinois; and the Science Museum of Minnesota, St. Paul, Minnesota. In-depth, semistructured interviews were used to collect the data. The study embraced aspects of the phenomenological tradition and sought to derive a holistic understanding of the position and how expertise was built for it. The data were methodically coded and organized into themes prior to analysis. The data analysis found that the position consisted of numerous and varied activities, but the developers' primary roles were advocating for the visitor, storytelling, and mediating information and ideas. They conducted these activities in the context of a team and relied on an established exhibition planning process to guide their work. Developers described a process of learning exhibition development that was experiential in nature. Learning through daily practice was key, though they also consulted with mentors and relied on visitor studies to gauge the effectiveness of their work. They were adept at integrating prior knowledge gained from many aspects of their lives into their practice. The developers described several internal factors that contributed to their expertise development including the desire to help others, a natural curiosity about the world, a commitment to learning, and the ability to accept critique. They

  11. Optimal Design of a Center Support Quadruple Mass Gyroscope (CSQMG

    Tian Zhang

    2016-04-01

    Full Text Available This paper reports a more complete description of the design process of the Center Support Quadruple Mass Gyroscope (CSQMG, a gyro expected to provide breakthrough performance for flat structures. The operation of the CSQMG is based on four lumped masses in a circumferential symmetric distribution, oscillating in anti-phase motion, and providing differential signal extraction. With its 4-fold symmetrical axes pattern, the CSQMG achieves a similar operation mode to Hemispherical Resonant Gyroscopes (HRGs. Compared to the conventional flat design, four Y-shaped coupling beams are used in this new pattern in order to adjust mode distribution and enhance the synchronization mechanism of operation modes. For the purpose of obtaining the optimal design of the CSQMG, a kind of applicative optimization flow is developed with a comprehensive derivation of the operation mode coordination, the pseudo mode inhibition, and the lumped mass twisting motion elimination. The experimental characterization of the CSQMG was performed at room temperature, and the center operation frequency is 6.8 kHz after tuning. Experiments show an Allan variance stability 0.12°/h (@100 s and a white noise level about 0.72°/h/√Hz, which means that the CSQMG possesses great potential to achieve navigation grade performance.

  12. Double Star Research: A Student-Centered Community of Practice

    Johnson, Jolyon

    2016-06-01

    Project and team-based pedagogies are increasingly augmenting lecture-style science classrooms. Occasionally, university professors will invite students to tangentially partcipate in their research. Since 2006, Dr. Russ Genet has led an astronomy research seminar for community college and high school students that allows participants to work closely with a melange of professional and advanced amatuer researchers. The vast majority of topics have centered on measuring the position angles and searations of double stars which can be readily published in the Journal of Double Star Observations. In the intervening years, a collaborative community of practice (Wenger, 1998) formed with the students as lead researchers on their projects with the guidance of experienced astronomers and educators. The students who join the research seminar are often well prepared for further STEM education in college and career. Today, the research seminar involves multile schools in multiple states with a volunteer educator acting as an assistant instructor at each location. These assistant instructors interface with remote observatories, ensure progress is made, and recruit students. The key deliverables from each student team include a published research paper and a public presentation online or in-person. Citing a published paper on scholarship and college applications gives students' educational carreers a boost. Recently the Journal of Double Star Observations published its first special issue of exlusively student-centered research.

    Latov, Norman; Vo, Mary L; Chin, Russell L; Carey, Bridget T; Langsdorf, Jennifer A; Feuer, Naomi T

    2016-06-01

    Abnormal concentrations of nutritional factors were found in 24.1% of 187 patients with neuropathy who were newly seen at our academic neuropathy referral center over a 1-year period. All patients presented with sensory axonal or small fiber neuropathy. In 7.3%, they were present in association with at least one other identifiable cause for neuropathy. Elevated levels of pyridoxal phosphate or mercury occurred more frequently than deficiencies in vitamins B1, B12, or B6. The nutritional abnormalities are amenable to correction by dietary intervention. PMID:27224436

    2013-10-01

    Photoluminescent (PL) properties related to Te(4+) species in zinc borate glasses are examined. Broad emission was observed by the excitation of the PL excitation peak of Te(4+) present at the optical absorption edge. The emission intensity of Te(4+) in 5TeO(2)-50ZnO-45B(2)O(3) glass was thermally quenched in a temperature region over 100 K, suggesting that concentration quenching preferentially occurred. The lifetime of the emission was approximately 2.5 μs, which is characteristic of relaxation from the triplet excitation state of an ns(2)-type center. PMID:24081051

  17. Are we living near the center of a local void?

    Cusin, Giulia; Uzan, Jean-Philippe

    2016-01-01

    The properties of the cosmic microwave background (CMB) temperature and polarisation anisotropies measured by a static, off-centered observer located in a local spherically symmetric void, are described. In particular in this paper we compute, together with the standard 2- point angular correlation functions, the off-diagonal correlators, which are no more vanishing by symmetry. While the energy shift induced by the off-centered position of the observer can be suppressed by a proper choice of the observer velocity, a lensing-like effect on the CMB emission point remains. This latter effect is genuinely geometrical (e.g. non-degenerate with a boost) and reflects in the structure of the off-diagonal correlators. At lowest order in this effect, the temperature and polarisation correlation matrices have non-vanishing diagonal elements, as usual, and all the off-diagonal terms are excited. This particular signature of a local void model allows one, in principle, to disentangle geometrical effects from local kinema...

  18. A Synergistic Consequence Assessment Modeling Strategy for Emergency Operations Centers

    At the U.S. Department of Energy's Hanford Site, maintaining emergency preparedness and response capabilities is a high priority. A synergistic strategy has emerged for conducting consequence assessment modeling at the Hanford Site Emergency Operation Center (EOC). This strategy involves employing a two-pronged modeling approach. The first prong involves the use of fast, reliable, and locally hosted models to provide timely and conservative projections of the affected area and potential impacts. A key model used for this purpose is the Pacific Northwest National Laboratory?s APGEMS model. The second prong involves the use of sophisticated modeling resources that have greater functionality and flexibility but take longer to initialize, conduct a simulation, and deliver output products. This capability is provided by the National Atmospheric Release Advisory Center (NARAC). The Hanford EOC?s consequence assessment team has found it to be constructive to use both the APGEMS and NARAC models in their emergency preparedness training and exercises. Experience gained with the NARAC system has allowed Hanford EOC personnel to provide NARAC with constructive feedback on model usability, the appropriateness of some default modeling assumptions, and documentation needs. As a result of the synergism associated with using both modeling systems, the Hanford EOC is better positioned to efficiently assess potential consequences during an emergency response event and NARAC is better poised to provide improved modeling support for the Hanford region and other Department of Energy sites

  20. Center for Space Power, Texas A and M University

    Jones, Ken

    Johnson Controls is a 106 year old company employing 42,000 people worldwide with $4.7 billion annual sales. Though we are new to the aerospace industry we are a world leader in automobile battery manufacturing, automotive seating, plastic bottling, and facilities environment controls. The battery division produces over 24,000,000 batteries annually under private label for the new car manufacturers and the replacement market. We are entering the aerospace market with the nickel hydrogen battery with the help of NASA's Center for Space Power at Texas A&M. Unlike traditional nickel hydrogen battery manufacturers, we are reaching beyond the space applications to the higher volume markets of aircraft starting and utility load leveling. Though space applications alone will not provide sufficient volume to support the economies of scale and opportunities for statistical process control, these additional terrestrial applications will. For example, nickel hydrogen batteries do not have the environmental problems of nickel cadmium or lead acid and may someday start your car or power your electric vehicle. However you envision the future, keep in mind that no manufacturer moves into a large volume market without fine tuning their process. The Center for Space Power at Texas A&M is providing indepth technical analysis of all of the materials and fabricated parts of our battery as well as thermal and mechanical design computer modeling. Several examples of what we are doing with nickel hydrogen chemistry to lead to these production efficiencies are presented.

    2013-09-01

    Full Text Available OBJECTIVE: to identify and classify the degree of family risk in a Family Health Center by means of a multidimensional evaluation instrument. METHOD: a cross-sectional study, with a quantitative and descriptive design, which evaluated 927 families registered in the center, which covers five micro-areas. The Coelho and Savassi Scale was applied, this consisting of 13 sentinels of evaluation of the social risk, using secondary data available in the File A of the families' medical records, in the last trimester of 2011. The data was analyzed using the SPSS (Statistical Package for the Social Sciences for Windows software, version 18.0. RESULTS: among the families studied, 68.5% were classified as not being at risk. It was ascertained that the smallest proportion of at-risk families (8.2% was found in micro-area 1, and that micro-area 4 had the highest proportion (55.9%. The most-prevalent risk situations were poor conditions of basic sanitation, systemic arterial hypertension, diabetes mellitus and drug addiction. CONCLUSION: this study's results make it possible to create support for the planning of home visits, to implement health surveillance actions, and for health professionals to better understand the vulnerabilities of the families attended.

  2. Building a university and center for energy in Sumatra, Indonesia

    Szwilski, T. (Univ. of Kentucky, Lexington, KY (US))

    1991-08-01

    This paper reports that the Directorate General of Higher Education (DGHE) in Indonesia recognized the need to provide quality education to a rapidly expanding student population. This stimulus prompted DGHE to establish an Inter-University Center (IUC) for Energy in Palembang, Sumatra. The region was chosen because it is well endowed with large reserves of coal, petroleum and natural gas. The IUC will be one of many centers of excellence already established throughout Indonesia at more prestigious universities. Subsequently, funds were provided by the government of Indonesia to upgrade UNSRI. It currently has a small campus with very few physical facilities and a student population of about 9,000. The new campus will accommodate up to 20,000 students. It is presently being constructed on 300 hm{sup 2} (741 acres) of land 35 km (22 miles) south of Palembang, and a two-hour drive north of Bukit Asam, a large surface coal mine. There are many shortcomings in the energy sector in developing countries. Principal among these are the lack of experience and training of engineers and managers, inadequate training facilities and lack of familiarity with available new technology. Many key personnel in the energy industry graduate from universities with ill-designed curricula and inadequate and general support facilities.

    Abhay Gundgurthi

    2012-01-01

    Full Text Available Objectives: There is paucity of information regarding clinical profile of hypopituitarism from India. We report the clinical profile of hypopituitarism from a tertiary center in North India. Materials and Methods: This study was carried out in patients attending our endocrine center between January 2010 and December 2011. All new patients were studied prospectively and those registered before January 2010 retrospectively. Relevant clinical, hormonal, and imaging data were collected. Dynamic testing for pituitary functions was carried out as necessary. Hormonal deficiencies were defined as per prevailing recommendations. Results: This study included 113 subjects. The mean age was 38.6 ± 17.8 years (range, 4 - 76 years. There were 78 (69% males and 35 females (31%. There were 22 subjects aged ≤18 years (childhood and adolescence and 91 adults (>18 years. Visual disturbances were the most common presenting complaint (33%, though headache was the most common symptom (81%. Fifteen percent presented with pituitary apoplexy. Tumors comprised of 84% of cases. Hypogonadism (97% was the most common abnormality seen followed by hypothyroidism (83.2%, hypoadrenalism (79.6%, growth hormone deficiency (88.1% of the 42 patients tested, and diabetes insipidus (13.3%. Panhypopituitarism was seen in 104 (92% patients. There were no cases of hypopituitarism secondary to traumatic brain injury, subarachnoid hemorrhage, central nervous system infections, or cranial irradiation to extrasellar tumors. Conclusion: The most common cause of hypopituitarism at tertiary care center is pituitary tumors and the commonest presenting complaint is visual symptoms. Panhypopituitarism is present in 92% cases.

  6. A multi-pathway model for Photosynthetic reaction center

    Qin, M; Yi, X X

    2015-01-01

    Charge separation in light-harvesting complexes occurs in a pair of tightly coupled chlorophylls at the heart of photosynthetic reaction centers of both plants and bacteria. Recently it has been shown that quantum coherence can, in principle, enhance the efficiency of a solar cell, working like a quantum heat engine (QHE). Here, we propose a biological quantum heat engine (BQHE) motivated by Photosystem {\\rm II} reaction center (PS{\\rm II} RC) to describe the charge separation. Our model mainly considers two charge-separation pathways more than that in the published literature. The two pathways can interfere via cross-couplings and work together to enhance the charge-separation yields. We explore how these cross-couplings increase the current and voltage of the charge separation and discuss the advantages of multiple pathways in terms of current and power. The robustness of the BQHE against the charge recombination in natural PS{\\rm II} RC and dephasing induced by environments is also explored, and extension ...

Recently it has been shown that quantum coherence can, in principle, enhance the efficiency of a solar cell, working like a quantum heat engine. Here, we propose a biological quantum heat engine (BQHE) motivated by Photosystem II reaction center (PSII RC) to describe the charge separation. Our model mainly considers two charge-separation pathways which is more than that typically considered in the published literature. We explore how these cross-couplings increase the current and power of the charge separation and discuss the effects of multiple pathways in terms of current and power. The robustness of the BQHE against the charge recombination in natural PSII RC and dephasing induced by environments is also explored, and extension from two pathways to multiple pathways is made. These results suggest that noise-induced quantum coherence helps to suppress the influence of acceptor-to-donor charge recombination, and besides, nature-mimicking architectures with engineered multiple pathways for charge separations might be better for artificial solar energy devices considering the influence of environments.

  8. MCPB.py: A Python Based Metal Center Parameter Builder.

    Li, Pengfei; Merz, Kenneth M

    2016-04-25

    MCPB.py, a python based metal center parameter builder, has been developed to build force fields for the simulation of metal complexes employing the bonded model approach. It has an optimized code structure, with far fewer required steps than the previous developed MCPB program. It supports various AMBER force fields and more than 80 metal ions. A series of parametrization schemes to derive force constants and charge parameters are available within the program. We give two examples (one metalloprotein example and one organometallic compound example), indicating the program's ability to build reliable force fields for different metal ion containing complexes. The original version was released with AmberTools15. It is provided via the GNU General Public License v3.0 (GNU_GPL_v3) agreement and is free to download and distribute. MCPB.py provides a bridge between quantum mechanical calculations and molecular dynamics simulation software packages thereby enabling the modeling of metal ion centers. It offers an entry into simulating metal ions in a number of situations by providing an efficient way for researchers to handle the vagaries and difficulties associated with metal ion modeling.

  9. A comparative study of Spacecraft Control Centers and SCADA Systems

    In order to assure the remote control in fusion machines or in industrial processes, SCADA (Supervisory Control and Data Acquisition) systems are used while the remote control of space systems is assured by satellite control centers (SCC). In this series of slides the author studies the similarities, constraints and differences of both systems, the presentation is a view from the space side. The first similarity is the geographic distribution: globally one nominal control center and numerous worker/ research staff in many countries. SCC and SCADA scope commonalities include no direct access to the machine, no big red stop button, and large number of interdependent and highly dynamic parameters. Among functional commonalities we have synopsis, alarms or trend analysis for monitoring and for control we have on-board automatism, high speed on-board loop and low speed network loop for human decision and reflex actions. In space systems scheduling is a core task because access times depend on orbit and ground stations and there are very few security aspects except for launch and reliability is assured through hardware redundancy.

    Berdine, Hildegarde

    2007-01-01

    Objectives To enhance students' learning and confidence in their abilities to provide wellness screenings and disease counseling. Design An experiential rotation was implemented in January 2004 within the Center for Pharmacy Care, a pharmacist-coordinated, University-based wellness center that offers preventive health screenings, risk assessments, patient education, medication and lifestyle counseling, educational seminars, and referral for common health conditions, such as hypertension, diabetes and osteoporosis. Assessment A brief survey instrument consisting of both open-ended questions and ratings of perceived abilities and confidence to provide screening and counseling was administered to students prior to and upon completion of the experience. Results of the survey indicate that the experience significantly enhanced students' preparedness and confidence to conduct community-based wellness screenings. Conclusion Students gained confidence in implementing and conducting wellness programs and became motivated to incorporate such programs into their future practice. This experience can serve as a teaching model for other programs to achieve student conpetencies in helath promotion and disease prevention. PMID:17619649

  11. Analysis of a Hybrid Wing Body Center Section Test Article

    Wu, Hsi-Yung T.; Shaw, Peter; Przekop, Adam

    2013-01-01

    The hybrid wing body center section test article is an all-composite structure made of crown, floor, keel, bulkhead, and rib panels utilizing the Pultruded Rod Stitched Efficient Unitized Structure (PRSEUS) design concept. The primary goal of this test article is to prove that PRSEUS components are capable of carrying combined loads that are representative of a hybrid wing body pressure cabin design regime. This paper summarizes the analytical approach, analysis results, and failure predictions of the test article. A global finite element model of composite panels, metallic fittings, mechanical fasteners, and the Combined Loads Test System (COLTS) test fixture was used to conduct linear structural strength and stability analyses to validate the specimen under the most critical combination of bending and pressure loading conditions found in the hybrid wing body pressure cabin. Local detail analyses were also performed at locations with high stress concentrations, at Tee-cap noodle interfaces with surrounding laminates, and at fastener locations with high bearing/bypass loads. Failure predictions for different composite and metallic failure modes were made, and nonlinear analyses were also performed to study the structural response of the test article under combined bending and pressure loading. This large-scale specimen test will be conducted at the COLTS facility at the NASA Langley Research Center.

  13. A new job migration algorithm to improve data center efficiency

    Calzolari, Federico

    2012-01-01

    The under exploitation of the available resources risks to be one of the main problems for a computing center. The growing demand of computational power necessarily entails more complex approaches in the management of the computing resources, with particular attention to the batch queue system scheduler. In a heterogeneous batch queue system, available for both serial single core processes and parallel multi core jobs, it may happen that one or more computational nodes composing the cluster are not fully occupied, running a number of jobs lower than their actual capability. A typical case is represented by more single core jobs running each one over a different multi core server, while more parallel jobs - requiring all the available cores of a host - are queued. A job rearrangement executed at runtime is able to free extra resources, in order to host new processes. We present an efficient method to improve the computing resources exploitation.

  14. Automated Determination of a Package's Center of Mass

    Ayaz Hemani

    2010-01-01

    Full Text Available In order to address the issue of increased efficiency and better planning for parcel shipments, an automated computer program was developed in Microsoft Excel that calculates center of mass and moments of mass with greater speed and reliability than currently implemented systems. This simple program requires only a variable density function and limits of integration for a given object as input within the spreadsheet system. Once the required input has been provided, a series of chain calculations, with the help of a Visual Basic for Applications (VBA script, is able to process the input, which is done through integration and a Riemann sum. Furthermore, the foundation of the program can also be used for calculating other physical quantities of interest such as the moment of inertia or surface area of an object.

  15. Imaging a boson star at the Galactic center

    Vincent, F H; Grandclement, P; Gourgoulhon, E; Straub, O

    2015-01-01

    Millimeter very long baseline interferometry will soon produce accurate images of the closest surroundings of the supermassive compact object at the center of the Galaxy, Sgr A*. These images may reveal the existence of a central faint region, the so-called shadow, which is often interpreted as the observable consequence of the event horizon of a black hole. In this paper, we compute images of an accretion torus around Sgr A* assuming this compact object is a boson star, i.e. an alternative to black holes within general relativity, with no event horizon and no hard surface. We show that very relativistic rotating boson stars produce images extremely similar to Kerr black holes, showing in particular shadow-like and photon-ring-like structures. This result highlights the extreme difficulty of unambiguously telling the existence of an event horizon from strong-field images.

  16. A special issue on the patient-centered medical home.

    Blount, Alexander

    2010-12-01

    This special issue on the Patient-Centered Medical Home (PCMH) reflects its times. At the present time, the PCMH is an aspirational model with a few pilots functioning well around the country. How long the current period of idealism, fueled by the energy of early adopters, the consensus of diverse stakeholders, and the dollars of the Affordable Care Act will continue is anybody's guess. Representing the thinking of some of the best minds in the field, the articles in this issue have an aspirational and idealistic tone as much as a descriptive and analytic one. A year ago the balance would have been tipped more toward idealism and model building and a year from now it would, in all likelihood, tip more toward model description and analysis. The authors in this volume have been personally responsible for helping to move behavioral health to a more central position in the PCMH model. PMID:21299276

  17. A framework for intelligent reliability centered maintenance analysis

    To improve the efficiency of reliability-centered maintenance (RCM) analysis, case-based reasoning (CBR), as a kind of artificial intelligence (AI) technology, was successfully introduced into RCM analysis process, and a framework for intelligent RCM analysis (IRCMA) was studied. The idea for IRCMA is based on the fact that the historical records of RCM analysis on similar items can be referenced and used for the current RCM analysis of a new item. Because many common or similar items may exist in the analyzed equipment, the repeated tasks of RCM analysis can be considerably simplified or avoided by revising the similar cases in conducting RCM analysis. Based on the previous theory studies, an intelligent RCM analysis system (IRCMAS) prototype was developed. This research has focused on the description of the definition, basic principles as well as a framework of IRCMA, and discussion of critical techniques in the IRCMA. Finally, IRCMAS prototype is presented based on a case study

  18. Evolution of a black hole at the center of GRB

    Lee, H K; Lee, Hyun Kyu; Kim, Hui-Kyung

    2002-01-01

    Using a simplified model of a black hole-accretion disk system which is dominated by Poynting flux, the evolution of the central black hole which is supposed to be powering GRB is discussed. It is demonstrated explicitly that there is a lower limit on the angular momentum parameter for a given GRB energy. It is found that the most energetic GRBs can only accommodate relatively rapid-rotating black holes at the center. For a set of GRBs for which the isotropic energies and T_90s are known, the effect of the disk mass and the magnetic field on the horizon are discussed quantitatively. It is found that the magnetic field has little influence on the energy but affects the GRB duration as expected. The role of the disk mass is found to be significant in determining both the energy and the duration.

  19. Galactic Center Gamma-Ray Excess through a Dark Shower

    Freytsis, Marat; Tsai, Yuhsin

    2014-01-01

    The reported excess of $\\gamma$-rays, emitted from an extended region around the galactic center, has a distribution and rate suggestive of an origin in dark matter (DM) annihilations. The conventional annihilation channels into standard model (SM) $b$ quarks or $\\tau$ leptons may, however, be in tension with various experimental constraints on antiproton and positron emissions. We present a framework that is free from such constraints. The key idea is that the mediators between the dark matter and the SM are themselves part of a strongly coupled sector: a hidden valley. In this scenario, the dark matter particles annihilate only into hidden quarks that subsequently shower and hadronize. Hidden quark effective couplings to SM hypercharge allow the lightest hidden bound states to subsequently decay into SM photons, producing the observed photon energy spectrum. Associated production of SM fermions is, in contrast, electroweak loop and helicity-suppressed. We find that, generically, $\\sim 10$ GeV DM provides a ...

  20. A Multidimensional Data Warehouse for Community Health Centers.

    Kunjan, Kislaya; Toscos, Tammy; Turkcan, Ayten; Doebbeling, Brad N

    2015-01-01

    Community health centers (CHCs) play a pivotal role in healthcare delivery to vulnerable populations, but have not yet benefited from a data warehouse that can support improvements in clinical and financial outcomes across the practice. We have developed a multidimensional clinic data warehouse (CDW) by working with 7 CHCs across the state of Indiana and integrating their operational, financial and electronic patient records to support ongoing delivery of care. We describe in detail the rationale for the project, the data architecture employed, the content of the data warehouse, along with a description of the challenges experienced and strategies used in the development of this repository that may help other researchers, managers and leaders in health informatics. The resulting multidimensional data warehouse is highly practical and is designed to provide a foundation for wide-ranging healthcare data analytics over time and across the community health research enterprise.

  1. Westinghouse Nuclear Core Design Training Center - a design simulator

    The emergence of more powerful computing technology enables nuclear design calculations to be done on workstations. This shift to workstation usage has already had a profound effect in the training area. In 1991, the Westinghouse Electric Corporation's Commercial Nuclear Fuel Division (CNFD) developed and implemented a Nuclear Core Design Training Center (CDTC), a new concept in on-the-job training. The CDTC provides controlled on-the-job training in a structured classroom environment. It alllows one trainer, with the use of a specially prepared training facility, to provide full-scope, hands-on training to many trainees at one time. Also, the CDTC system reduces the overall cycle time required to complete the total training experience while also providing the flexibility of individual training in selected modules of interest. This paper provides descriptions of the CDTC and the respective experience gained in the application of this new concept

  2. Relativistic center-vortex dynamics of a confining area law

    We offer a physicist's proof that center-vortex theory requires the area in the (quenched) Wilson-loop area law to involve an extremal area. This means that, unlike in string-theory-inspired models of confining flux tubes, area-law dynamics is determined by integrating over Wilson loops only, not over surface fluctuations for a fixed loop. Fluctuations leading to perimeter-law corrections come from loop fluctuations as well as integration over finite-thickness center-vortex collective coordinates. In d=3 (or d=2+1) we exploit a contour form of the extremal area in isothermal (conformally flat metric on the surface) coordinates which is similar to d=2 (or d=1+1) QCD in many respects, except that there are both quartic and quadratic terms in the action. One major result is that at large angular momentum l in d=3+1 the center-vortex extremal-area picture yields a linear Regge trajectory with a Regge slope-string tension product α'(0)KF of 1/(2π), which is the canonical Veneziano or string value. In a curious effect traceable to retardation, the quark kinetic terms in the action vanish relative to area-law terms in the large-l limit, in which light-quark masses ∼KF1/2 are negligible. This corresponds to string-theoretic expectations, even though we emphasize that the extremal-area law is not a string theory quantum mechanically. We show how some quantum trajectory fluctuations as well as nonleading classical terms for finite mass yield corrections scaling with l-1/2. We compare to old semiclassical calculations of relativistic (massless) qq-bar bound states at large l, which also yield asymptotically linear Regge trajectories, finding agreement with a naive string picture (classically, not quantum mechanically) and disagreement with an effective-propagator model. We show that contour forms of the area law can be expressed in terms of Abelian gauge potentials, and we relate this to old work of Comtet

  3. Functional Centering

    Hahn, M

    1996-01-01

    Based on empirical evidence from a free word order language (German) we propose a fundamental revision of the principles guiding the ordering of discourse entities in the forward-looking centers within the centering model. We claim that grammatical role criteria should be replaced by indicators of the functional information structure of the utterances, i.e., the distinction between context-bound and unbound discourse elements. This claim is backed up by an empirical evaluation of functional centering.

    SCADA systems as used in fusion physics or industrial plants and control centers as used in space systems share the same global goal: monitoring and controlling a remote complex and costly device securely. These two fields have developed parallel technologies when facing similar concerns but up to now they have not exchanged much information and experience together. This paper is a comparison between SCADA systems and Spacecraft Control Centers (SCC), seen from the space field side. The first part of the paper explains the purpose of a SCC and its place in the ground segment of a global space system. The second part dives into the architectural and functional aspects of SCC and SCADA systems. It attempts to extract a common underlying structure and identify the specificities of each domain. It appears that many things are already generic enough and that similar solutions brought by current state of the art technology are used in both fields (mimics, trend analysis, soft points/derived parameters...). Some discrepancies appear however even for concepts that are not dedicated to the science field. They may come from historical reasons or priorities. As an example, the networking and computing aspects sometimes differ. The third part starts from these discrepancies to show how space systems have evolved and how there are made now. One major change was a switch from proprietary to open protocols started a long time ago and mostly visible in the standardization committees. In addition to the space specific standards acknowledged by spacecraft, launchers, tracking stations or control centers manufacturers, the wider industry standards are also mandatory (ethernet, TCP/IP...). Ground segments are now often built from separate components coming from various providers, some custom made, some generic, some open-source, some new, some reused. The life cycle of an operational system being quite long (typically 20 years) with regard to the fast pace of computing industry, this

  6. The Galactic Center - an AGN on a starvation diet

    Biermann, P L; Biermann, Heino Falcke & Peter L.

    1993-01-01

    The Galactic Center shows evidence for the presence of three important AGN ingredients: a Black Hole ($M_\\bullet\\sim10^6M_\\odot$), an accretion disk ($10^{-8.5} - 10^{-7} M_\\odot/{\\rm yr}$) and a powerful jet (jet power $\\ge$ 10\\% disk luminosity). However, the degree of activity is very low and can barely account for the energetics of the whole central region. Neverthelss, in the very inner arsecond the central engine becomes dominant and provides an interesting laboratory for the physics of central engines (Black Holes) in galactic nuclei. We therefore give an overall picture of the central arcsecond where we link the radio emission and the heating of the ambient medium to a weakly accreting disk surrounding a massive Black Hole.

  7. A reliability-centered maintenance program for primary reactor pumps

    Reactor coolant and recirculation pumps require significant outage times to repair and, as a consequence, are a major contributor to plant downtime and lost capacity. To improve reliability of these primary reactor pumps, a comprehensive preventative maintenance program has been developed using the principles of reliability-centered maintenance. This method establishes the frequency of past failures, estimates the probability of future occurrences, and assesses the effect of all potential functional failures of the pump. Maintenance tasks are then defined to address those specific failure modes that have the largest probability of occurrence and the greatest impact on plant availability. Benefits include: improved reliability, a maintenance program that satisfies the industry initiative on maintenance, prudence documentation in support of unforeseen outages, and documented justification for rate-base increases for maintenance costs

  8. An example of a United States Nuclear Research Center

    Under the likely scenario in which public support for nuclear energy remains low and fossil fuels continue to be abundant and cheap, government supported nuclear research centers must adapt their missions to ensure that they tackle problems of current significance. It will be critical to be multidisciplinary, to generate economic value, and to apply nuclear competencies to current problems. Addressing problems in nuclear safety, D and D, nuclear waste management, nonproliferation, isotope production are a few examples of current needs in the nuclear arena. Argonne's original mission, to develop nuclear reactor technology, was a critical need for the U.S. in 1946. It would be wise to recognize that this mission was a special instance of a more general one--to apply unique human and physical capital to long term, high risk technology development in response to society's needs. International collaboration will enhance the collective chances for success as the world moves into the 21st century

  9. A proposal of the ITER remote participation center in Japan

    In modern fusion experiments, as many collaborators in distributed locations use a few large experimental devices, such as ITER and LHD (Large Helical Device), remote participation technologies become more important. The ITER Remote Experimentation Center is to be established in the International Fusion Energy Research Center (IFERC) in Rokkasho site (Japan). We have been working on the remote participation system, known as SNET, which has been developed using the SINET3, the high-speed network operated by the National Institute of Computer Sciences (NII) since 2004. The SINET3 is also 10 Gbps reachable to academic networks, ESnet in Usa and GEANT in EU. This paper discusses about the data analysis in the ITER remote participation center using a super computer. One of the most crucial issues is that the data transfer rate is much less than that expected from the network bandwidth and the data transfer rate problem should be harder as the distance is longer due to the TCP/IP protocol. The distance between Rokkasho and Cadarache is 15,000 km in fiber length. The ITER experimental data may be 1 TB per shot, considering the LHD experimental data is 10 GB per shot. We have developed a new data transfer technology to obtain 9 Gbps in the case of the network bandwidth of 10 Gbps. By extending this technology, the data transfer rate of 90 Gbps may be available, and the ITER data will be able to transfer within 100 sec per shot. In the Rokkasho site, we can store the whole ITER experimental data as a mirror site, and we can analyze the ITER data by using the supercomputer. Since the data analysis software in the supercomputer is developed by collaborators in the world, the security control will be another issue. The supercomputer might work as a calculating engine behind data analysis server, which the most physicists would access. Development of technologies to realize the ITER remote participation is challenging. This document is composed of an abstract followed by the

  10. [Academic procrastination in clients of a psychotherapeutic student counselling center].

    Jamrozinski, Katja; Kuda, Manfred; Mangholz, Astrid

    2009-01-01

    The start of university education is the beginning of a new phase of life for young adults, which requires significant psychosocial adjustments. Sociobiographical data, clinical symptoms, characteristics of education, work attitude, and career perspectives were gathered from 152 clients by a psychotherapeutic student counselling center to evaluate characteristics of students with and without academic procrastination. The procrastination group comprised heightened numbers of students who had changed universities, and people with suboptimal career prospects and career targets. These subjects were more often male and showed increased incidences of drug- and alcohol problems, as well as a lack of planning of the future. Furthermore, they had larger amounts of their study self-financed. On the basis of these results, concrete recommendations for preventive measures to improve on-time completion of study, and to prevent student drop-out are presented. PMID:18988140

  11. Engineering system dynamics a unified graph-centered approach

    Brown, Forbes T

    2006-01-01

    For today's students, learning to model the dynamics of complex systems is increasingly important across nearly all engineering disciplines. First published in 2001, Forbes T. Brown's Engineering System Dynamics: A Unified Graph-Centered Approach introduced students to a unique and highly successful approach to modeling system dynamics using bond graphs. Updated with nearly one-third new material, this second edition expands this approach to an even broader range of topics. What's New in the Second Edition? In addition to new material, this edition was restructured to build students' competence in traditional linear mathematical methods before they have gone too far into the modeling that still plays a pivotal role. New topics include magnetic circuits and motors including simulation with magnetic hysteresis; extensive new material on the modeling, analysis, and simulation of distributed-parameter systems; kinetic energy in thermodynamic systems; and Lagrangian and Hamiltonian methods. MATLAB(R) figures promi...

  12. The role of nonprofessional volunteers in a Suicide Prevention Center.

    Heilig, S M; Farberow, N L; Litman, R E; Shneidman, E S

    1968-08-01

    The procedures in the selection, training and supervision of 10 nonprofessional volunteers, to provide direct therapeutic crisis services to patients in a Suicide Prevention Center are described. One year's experience indicates a high degree of proficiency achieved by the volunteer in the handling of suicidal crises. The volunteers' reactions to the program are reported. Significant problems for the agency emerged in reference to precipitous increase in size of staff communication, and for the volunteer, in stimulation of problems of identity and selfconcept. The comments are limited to agency situations involving the use of nonprofessional volunteers in regular collaboration with a professional staff. Other models, such as entirely volunteer staffed groups, must be evaluated separately. PMID:24185391

  13. The discourse functions of Italian subjects a centering approach

    This paper examines the discourse functions that different types of subjects perform in Italian within the centering framework. I build on my previous work (COLING90) that accounted for the alternation of null and strong pronouns in subject position. I extend my previous analysis in several ways: for example, I refine the notion of {\\sc continue} and discuss the centering functions of full NPs.

  16. Secure Remote Access Issues in a Control Center Environment

    Pitts, Lee; McNair, Ann R. (Technical Monitor)

    2002-01-01

    The ISS finally reached an operational state and exists for local and remote users. Onboard payload systems are managed by the Huntsville Operations Support Center (HOSC). Users access HOSC systems by internet protocols in support of daily operations, preflight simulation, and test. In support of this diverse user community, a modem security architecture has been implemented. The architecture has evolved over time from an isolated but open system to a system which supports local and remote access to the ISS over broad geographic regions. This has been accomplished through the use of an evolved security strategy, PKI, and custom design. Through this paper, descriptions of the migration process and the lessons learned are presented. This will include product decision criteria, rationale, and the use of commodity products in the end architecture. This paper will also stress the need for interoperability of various products and the effects of seemingly insignificant details.

    2007-03-01

    In November 2005, the Energy & Environmental Research Center (EERC), ePowerSynergies, Inc. (ePSI), and Resurfice Corporation teamed to develop, produce, and demonstrate the world's first and only fuel cell-powered ice resurfacer. The goals of this project were: {sm_bullet} To educate the public on the readiness, practicality, and safety of fuel cells powered by hydrogen fuel and {sm_bullet} To establish a commercialization pathway in an early-adopter, niche market. The vehicle was developed and produced in a short 3-month span. The vehicle made its world debut at U.S. Senator Byron Dorgan's (D-ND) 2005 Hydrogen Energy Action Summit. Subsequently, the vehicle toured North America appearing at numerous public events and conferences, receiving much attention from international media outlets.

    2010-10-15

    The performance of bio-photovoltaic devices with a monolayer of the immobilized photosynthetic reaction center (RC) is generally low because of weak light absorption and poor charge transfer between the RC and the electrode. In this paper, a new bio-photovoltaic device is described in which the RC is dissolved in the electrolyte of an electrochemical cell. The charges generated by the illuminated RC are transferred to electrodes via mediators. The difference between the reaction rates of two types of mediator at the electrode surfaces determines the direction of the photocurrent in the device. Experimental results show that the magnitude of the photocurrent is proportional to the incident light intensity, and the current increases nonlinearly with an increase in the RC concentration in the electrolyte. With further optimization this approach should lead to devices with improved light absorption.

  19. A Jet Model of the Galactic Center Nonthermal Radio Filaments

    Yusef-Zadeh, F

    2004-01-01

    Protostellar sources in star forming regions are responsible for driving jets with flow velocities ranging between 300 and 400 km s$^{-1}$. This class of jets consists of highly collimated outflows which include thermal knots with number densities estimated to be greater than that of their ambient medium. On the other hand, extragalactic FR I jets consist of light fluid with low Mach number burrowing through a denser medium as the magnetized jets radiate nonthermal emission. Both protostellar and extragalactic jets are believed to be launched by accretion disks. Here we consider a jet model in which the characteristics common to both protostellar and extragalactic jets are used to explain the origin of nonthermal filaments in the Galactic center region. We argue that these filaments are analogous to FR I extragalactic sources but are launched by embedded young stars or clusters of stars in star-forming regions.

  20. Electric power transmission for a Hanford Nuclear Energy Center (HNEC)

    The original study of transmission for a Hanford Nuclear Energy Center (HNEC), which was completed in September 1975, was updated in June 1978. The present 1983 revision takes cognizance of recent changes in the electric power situation of the PNW with respect to: (1) forecasts of load growth, (2) the feasibility of early use of 1100 kV transmission, and (3) the narrowing opportunities for siting nuclear plants in the region. The purpose of this update is to explore and describe additions to the existing transmission system that would be necessary to accommodate three levels of generation at HNEC. Comparisons with a PNW system having new thermal generating capacity distributed throughout the marketing region are not made as was done in earlier versions

  1. Outcome of major cardiac injuries at a Canadian trauma center

    Lamy Andre

    2002-06-01

    Full Text Available Abstract Background Canadian trauma units have relatively little experience with major cardiac trauma (disruption of a cardiac chamber so injury outcome may not be comparable to that reported from other countries. We compared our outcomes to those of other centers. Methods Records of patients suffering major cardiac trauma over a nine-year period were reviewed. Factors predictive of outcome were analyzed. Results Twenty-seven patients (11 blunt and 16 penetrating with major cardiac trauma were evaluated. Injury severity scores (ISS were similar for blunt (49.6 ± 16.6 and penetrating (39.5 ± 21.6, p = 0.20 injuries. Five of 11 blunt trauma patients, and 9 of 16 penetrating trauma patients, had detectable vital signs on hospital arrival (p = 0.43. Ten patients underwent emergency department thoracotomy and 11 patients had cardiac repair in the operating theatre. Eleven patients survived and 16 died. Survivors had a lower ISS (33.7 ± 15.4 than non-survivors (50.4 ± 20.4; p = 0.03. Two of 11 blunt trauma patients and 9 of 16 penetrating trauma patients survived (p = 0.06. Eleven of 14 patients with detectable vital signs survived; all 13 without detectable vital signs died (p = 0.00003. Ten of eleven patients treated in the operating theatre survived, while only one of the other 16 patients survived (p = 0.00002. Conclusions Patients with major cardiac injuries and detectable vital signs on hospital arrival can be salvaged by prompt surgical intervention in the operating theatre. Major cardiac injuries are infrequently encountered at our center but patient survival is comparable to that reported from trauma units in other countries.

  2. Students-exhibits interaction at a science center

    Botelho, Agostinho; Morais, Ana M.

    2006-12-01

    In this study we investigate students' learning during their interaction with two exhibits at a science center. Specifically, we analyze both students' procedures when interacting with exhibits and their understanding of the scientific concepts presented therein. Bernstein's theory of pedagogic discourse (1990, 2000) provided the sociological foundation to assess the exhibit-student interaction and allowed analysis of the influence of the characteristics of students, exhibits, and interactions on students' learning. Eight students (ages 12ndash;13 years of age) with distinct sociological characteristics participated in the study. Several findings emerged from the results. First, the characteristics of the students, exhibits, and interactions appeared to influence student learning. Second, to most students, what they did interactively (procedures) seems not to have had any direct consequence on what they learned (concept understanding). Third, the data analysis suggest an important role for designers and teachers in overcoming the limitations of exhibit-student interaction.

  3. Blunt pancreatic trauma: experience at a rural referral center.

    Timberlake, G A

    1997-03-01

    The objective of this study was to compare mechanism of injury, treatment methods, and outcome of blunt pancreas trauma patients transferred from another hospital to those of patients brought directly from the scene. A retrospective review was conducted of 6078 patients treated at a Level I trauma center from 1/1/90 to 12/31/94. Blunt pancreas injury was found in 39 (0.64%) patients (mean age, 33.2 years). Mechanism of injury included 34 (87%) motor vehicle crashes, 3 (8%) motorcycle crashes, and 2 (5%) other injuries. There were 11 transfer patients (28%), and 28 (72%) admitted directly from the scene. Eighty-two per cent of the motor vehicle crash patients were unrestrained, and 35 per cent had ethanol intoxication. Exploratory laparotomy was performed on 32 (82%); eight (25%) required repair or resection; 22 (69%) had trivial injuries, at most requiring drainage; and two (6.3%) exsanguinated. No patients required Whipple resection or pancreatiocojejunostomy. At operation, an average of 2.5 associated intra-abdominal injuries were found. Overall survival was 35 of 39 (90%). Among the patients brought directly to the trauma center, 93 per cent survived, whereas survival among transferred patients was 82 per cent (chi2 = 0.19; P = 0.66). Blunt pancreatic injuries vary in severity, but radical resection is rarely required. Lack of safety restraint and ethanol use are major risk factors. Despite the high likelihood of associated injuries, survivability is high. No difference in outcome was seen between directly admitted and transferred patients. PMID:9036900

  4. Journey to the Center of a Neutron Star

    Wanjek, Christopher

    2003-01-01

    A neutron star is not a place most would want to visit. This dense remnant of a collapsed star has a magnetic field billions of times stronger than Earth's, enough to shuffle your body's molecules long before you even land. The featureless surface is no fun either. Crushing gravity ensures that the star is a near perfect sphere, compressing all matter so that a sand-grain-sized scoop of neutron star material would weigh as much as a battleship on Earth. At least black holes offer the promise of funky singularity, time warps, and the Odyssean temptation to venture beyond a point of no return. What s a journey to a neutron star good for, one might ask? Well, for starters, it offers the possibility of confirming a theorized state of matter called quark-gluon plasma, which likely existed for a moment after the Big Bang and now might only exist in the superdense interiors of neutron stars. Beneath the neutron star crust, a kilometer-thick plate of crystalline matter, lies the great unknown. The popular theory is that the neutron star interior is made up of a neutron superfluid - a fluid without friction. With the help of two NASA satellites - the Rossi X-Ray Timing Explorer and the Chandra X-Ray Observatory - scientists are journeying to the center of a neutron star. Matter might be so compressed there that it breaks down into quarks, the building blocks of protons and neutrons, and gluons, the carrier of the strong nuclear force. To dig inside a neutron star, no simple drill bit will do. Scientists gain insight into the interior through events called glitches, a sudden change in the neutron star s precise spin rate. 'Glitches are one of the few ways we have to study the neutron star interior,' says Frank Marshall of NASA s Goddard Space Flight Center, who has used the Rossi Explorer to follow the escapades of the glitchiest of all neutron stars, dubbed the Big Glitcher and known scientifically as PSR J0537-6910.

    2016-08-01

    We propose an efficient scheme for the realization of high-fidelity quantum storage in a hybrid system with a photonic molecule and a diamond nitrogen vacancy (NV) center. The scheme holds the advantages of both photonic crystal cavities and NV centers. Meanwhile, the influence of quantum-computing process on quantum memory can be effectively eliminated by separating the processor and memory units. Moreover, the scheme is experimentally feasible with currently available technology.

  15. THIS IS A DRILL (HANFORD EMERGENCY OPERATIONS CENTER IN ACTION)

    ''This is a drill'', these are the words that we're directed to say before and after any verbal communication with other personnel while participating in training exercises for the Hanford Site Emergency Operations Center (EOC). The EOC has multiple components and many personnel outside of the EOC participate in training exercises. ''This is a drill'', describes the operations of the EOC Unified Dose Assessment Center (UDAC) and the tools used by personnel operating the UDAC. The functions and composition of the EOC, UDAC and related organizations are governed by the Hanford Emergency Management Plan for the US Department of Energy (DOE), Richland Operations Office (RL) and Office of River Protection (ORP) (DOE/RL-94-02, Hanford Emergency Management Plan). This plan presents--in a single document--an overview of the emergency-management program for the entire Hanford Site. At the heart of the UDAC operations is the question, ''How, and in what direction, would a plume of radioactivity potentially disperse in the event of an accident that released radioactive material?'' Key elements of projecting or predicting the impact are the source term (what materials and how much have been released), the details of the current and projected weather conditions, and analyses models that will calculate the predicted movement of the material. ''This is a drill'' loosely describes the organization of the UDAC, the way the personnel go about doing their jobs, and the tools they use to get the answers required by those managing the exercise or event. Key tools are used to evaluate and predict the consequences of a release of hazardous materials: maps and atlases; environmental databases such as the Waste Information Data System (WIDS); scenario-driven weather conditions (or real weather-station information provided by personnel from the Pacific Northwest National Laboratory [PNNL]); and analysis codes like MetView (Meteorological Display and Assessment Tool) and APGEMS (models

  16. Reliability Centered Maintenance as a tool for plant life extension

    Currently in the nuclear industry there is a growing interest in lowering the cost and complexity of maintenance activities while at the same time improving plant reliability and safety in an effort to prepare for the technical and regulatory challenges of life extension. This seemingly difficult task is being aided by the introduction of a maintenance philosophy developed originally by the airline industry and subsequently applied with great success both in that industry and the U.S. military services. Reliability Centered Maintenance (RCM), in its basic form, may be described as a consideration of reliability and maintenance problems from a systems level approach, allowing a focus on preservation of system function as the aim of a maintenance program optimized for both safety and economics. It is this systematic view of plant maintenance, with the emphasis on overall functions rather than individual parts and components which sets RCM apart from past nuclear plant maintenance philosophies. It is also the factor which makes application of RCM an ideal first step in development of strategies for life extension, both for aging plants, and for plants just beginning their first license term.

  17. Building a Prototype of LHC Analysis Oriented Computing Centers

    Bagliesi, G.; Boccali, T.; Della Ricca, G.; Donvito, G.; Paganoni, M.

    2012-12-01

    A Consortium between four LHC Computing Centers (Bari, Milano, Pisa and Trieste) has been formed in 2010 to prototype Analysis-oriented facilities for CMS data analysis, profiting from a grant from the Italian Ministry of Research. The Consortium aims to realize an ad-hoc infrastructure to ease the analysis activities on the huge data set collected at the LHC Collider. While “Tier2” Computing Centres, specialized in organized processing tasks like Monte Carlo simulation, are nowadays a well established concept, with years of running experience, site specialized towards end user chaotic analysis activities do not yet have a defacto standard implementation. In our effort, we focus on all the aspects that can make the analysis tasks easier for a physics user not expert in computing. On the storage side, we are experimenting on storage techniques allowing for remote data access and on storage optimization on the typical analysis access patterns. On the networking side, we are studying the differences between flat and tiered LAN architecture, also using virtual partitioning of the same physical networking for the different use patterns. Finally, on the user side, we are developing tools and instruments to allow for an exhaustive monitoring of their processes at the site, and for an efficient support system in case of problems. We will report about the results of the test executed on different subsystem and give a description of the layout of the infrastructure in place at the site participating to the consortium.

  18. Neighborhood greenspace and health in a large urban center

    Kardan, Omid; Gozdyra, Peter; Misic, Bratislav; Moola, Faisal; Palmer, Lyle J.; Paus, Tomáš; Berman, Marc G.

    2015-07-01

    Studies have shown that natural environments can enhance health and here we build upon that work by examining the associations between comprehensive greenspace metrics and health. We focused on a large urban population center (Toronto, Canada) and related the two domains by combining high-resolution satellite imagery and individual tree data from Toronto with questionnaire-based self-reports of general health perception, cardio-metabolic conditions and mental illnesses from the Ontario Health Study. Results from multiple regressions and multivariate canonical correlation analyses suggest that people who live in neighborhoods with a higher density of trees on their streets report significantly higher health perception and significantly less cardio-metabolic conditions (controlling for socio-economic and demographic factors). We find that having 10 more trees in a city block, on average, improves health perception in ways comparable to an increase in annual personal income of $10,000 and moving to a neighborhood with $10,000 higher median income or being 7 years younger. We also find that having 11 more trees in a city block, on average, decreases cardio-metabolic conditions in ways comparable to an increase in annual personal income of $20,000 and moving to a neighborhood with $20,000 higher median income or being 1.4 years younger.

  19. A person-centered approach to moral judgment.

    Uhlmann, Eric Luis; Pizarro, David A; Diermeier, Daniel

    2015-01-01

    Both normative theories of ethics in philosophy and contemporary models of moral judgment in psychology have focused almost exclusively on the permissibility of acts, in particular whether acts should be judged on the basis of their material outcomes (consequentialist ethics) or on the basis of rules, duties, and obligations (deontological ethics). However, a longstanding third perspective on morality, virtue ethics, may offer a richer descriptive account of a wide range of lay moral judgments. Building on this ethical tradition, we offer a person-centered account of moral judgment, which focuses on individuals as the unit of analysis for moral evaluations rather than on acts. Because social perceivers are fundamentally motivated to acquire information about the moral character of others, features of an act that seem most informative of character often hold more weight than either the consequences of the act or whether a moral rule has been broken. This approach, we argue, can account for numerous empirical findings that are either not predicted by current theories of moral psychology or are simply categorized as biases or irrational quirks in the way individuals make moral judgments.

  20. Establishing a Secure Data Center with Remote Access: Preprint

    Gonder, J.; Burton, E.; Murakami, E.

    2012-04-01

    Access to existing travel data is critical for many analysis efforts that lack the time or resources to support detailed data collection. High-resolution data sets provide particular value, but also present a challenge for preserving the anonymity of the original survey participants. To address this dilemma of providing data access while preserving privacy, the National Renewable Energy Laboratory and the U.S. Department of Transportation have launched the Transportation Secure Data Center (TSDC). TSDC data sets include those from regional travel surveys and studies that increasingly use global positioning system devices. Data provided by different collecting agencies varies with respect to formatting, elements included and level of processing conducted in support of the original purpose. The TSDC relies on a number of geospatial and other analysis tools to ensure data quality and to generate useful information outputs. TSDC users can access the processed data in two different ways. The first is by downloading summary results and second-by-second vehicle speed profiles (with latitude/longitude information removed) from a publicly-accessible website. The second method involves applying for a remote connection account to a controlled-access environment where spatial analysis can be conducted, but raw data cannot be removed.

  2. Naturalistic Cognition: A Research Paradigm for Human-Centered Design

    Peter Storkerson

    2010-01-01

    Full Text Available Naturalistic thinking and knowing, the tacit, experiential, and intuitive reasoning of everyday interaction, have long been regarded as inferior to formal reason and labeled primitive, fallible, subjective, superstitious, and in some cases ineffable. But, naturalistic thinking is more rational and definable than it appears. It is also relevant to design. Inquiry into the mechanisms of naturalistic thinking and knowledge can bring its resources into focus and enable designers to create better, human-centered designs for use in real-world settings. This article makes a case for the explicit, formal study of implicit, naturalistic thinking within the fields of design. It develops a framework for defining and studying naturalistic thinking and knowledge, for integrating them into design research and practice, and for developing a more integrated, consistent theory of knowledge in design. It will (a outline historical definitions of knowledge, attitudes toward formal and naturalistic thinking, and the difficulties presented by the co-presence of formal and naturalistic thinking in design, (b define and contrast formal and naturalistic thinking as two distinct human cognitive systems, (c demonstrate the importance of naturalistic cognition in formal thinking and real-world judgment, (d demonstrate methods for researching naturalistic thinking that can be of use in design, and (e briefly discuss the impact on design theory of admitting naturalistic thinking as valid, systematic, and knowable.

  3. Probing a dark matter density spike at the Galactic Center

    Lacroix, Thomas; Silk, Joseph

    2013-01-01

    The dark matter halo profile in the inner galaxy is very uncertain. Yet its radial dependence towards the Galactic Center is of crucial importance for the determination of the gamma-ray and radio fluxes originating from dark matter annihilations. Here we use synchrotron emission to probe the dark matter energy distribution in the inner galaxy. We first solve the problem of the cosmic ray diffusion on very small scales, typically smaller than 10^{-3} pc by using a Green's function approach, and use this technique to quantify the effect of a spiky profile (rho(r) ~ r^{-7/3}) on the morphology and intensity of the synchrotron emission expected from dark matter. We illustrate our results using 10 GeV and 800 GeV candidate weakly interacting dark matter particles annihilating directly into e^+ e^-. Our most critical assumptions are that the dark matter is heavier than a few GeV and directly produces a reasonable amount of electrons and positrons in the galaxy. We conclude that dark matter indirect detection techni...

  4. An example of a United States Nuclear Research Center

    Bhattacharyya, S. K.

    1999-12-10

    Under the likely scenario in which public support for nuclear energy remains low and fossil fuels continue to be abundant and cheap, government supported nuclear research centers must adapt their missions to ensure that they tackle problems of current significance. It will be critical to be multidisciplinary, to generate economic value, and to apply nuclear competencies to current problems. Addressing problems in nuclear safety, D and D, nuclear waste management, nonproliferation, isotope production are a few examples of current needs in the nuclear arena. Argonne's original mission, to develop nuclear reactor technology, was a critical need for the U.S. in 1946. It would be wise to recognize that this mission was a special instance of a more general one--to apply unique human and physical capital to long term, high risk technology development in response to society's needs. International collaboration will enhance the collective chances for success as the world moves into the 21st century.

    2014-12-01

    Full Text Available This study describes and analyzes day-to-day issues in a Therapeutic Residential Care Center and the daily life characteristics of its residents. This case study was conducted in Caxias do Sul, based on an evaluation of the fourth generation together with a Methodology for Analyzing Everyday Life Networks. The following categories emerged: possibilities in the territory, participation and flexibility in household tasks, situations that mark living, employees who are mediators in conflict resolution, staff committed to the resident, freedom as a therapeutic tool, difficulties in daily life, and building of alliances. This study helped to get to know the structure of everyday life experienced by the residents, identifying some difficulties they face and the mechanisms used to overcome them, in addition to noticing that the professionals can be instrumental in strengthening a daily living that can be pluralized, busy, and enriched, while still respecting the uniqueness of each resident. doi: 10.5216/ree.v16i4.22923.

    2002-12-01

    Full Text Available Abstract Background This report describes the utility of hypnosis for patients who presented to a Pediatric Pulmonary Center over a 30 month period. Methods Hypnotherapy was offered to 303 patients from May 1, 1998 – October 31, 2000. Patients offered hypnotherapy included those thought to have pulmonary symptoms due to psychological issues, discomfort due to medications, or fear of procedures. Improvement in symptoms following hypnosis was observed by the pulmonologist for most patients with habit cough and conversion reaction. Improvement of other conditions for which hypnosis was used was gauged based on patients' subjective evaluations. Results Hypnotherapy was associated with improvement in 80% of patients with persistent asthma, chest pain/pressure, habit cough, hyperventilation, shortness of breath, sighing, and vocal cord dysfunction. When improvement was reported, in some cases symptoms resolved immediately after hypnotherapy was first employed. For the others improvement was achieved after hypnosis was used for a few weeks. No patients' symptoms worsened and no new symptoms emerged following hypnotherapy. Conclusions Patients described in this report were unlikely to have achieved rapid improvement in their symptoms without the use of hypnotherapy. Therefore, hypnotherapy can be an important complementary therapy for patients in a pediatric practice.

    The dark matter halo profile in the inner Galaxy is very uncertain. Yet its radial dependence toward the Galactic Center is of crucial importance for the determination of the gamma-ray and radio fluxes originating from dark matter annihilations. Here we use synchrotron emission to probe the dark matter energy distribution in the inner Galaxy. We first solve the problem of the cosmic ray diffusion on very small scales, typically smaller than 103 pc, by using a Green's function approach and use this technique to quantify the effect of a spiky profile [ρ(r)∝r-7/3] on the morphology and intensity of the synchrotron emission expected from dark matter. We illustrate our results using 10 and 800 GeV candidate weakly interacting dark matter particles annihilating directly into e+e-. Our most critical assumptions are that the dark matter is heavier than a few GeV and directly produces a reasonable amount of electrons and positrons in the Galaxy. We conclude that dark matter indirect detection techniques (including the Planck experiment) could be used to shed light on the dark matter halo profile on scales that lie beyond the capability of any current numerical simulations.

  8. Addressing underutilization of consumer health information resource centers: a formative study*

    Kennedy, May G.; Kiken, Laura; Shipman, Jean P.

    2008-01-01

    Problem: Four consumer health information centers in Richmond, Virginia, provide one-on-one assistance in accessing health information. Because they may not be fully utilized at present, an exploratory marketing study of factors affecting usage of the centers was conducted. Method: Observers counted center passers-by and tracked their paths. Also, brief intercept interviews were conducted with people who had just used a center, people nearby who could have used one but did not, and people on the street. Finally, in-depth individual interviews were conducted with key informants. Results: There was a high degree of satisfaction with the centers among users. Nonusers universally endorsed the center concept. However, most passers-by did not even glance at the centers, and intercept interviewees suggested better signage and promoting the resource centers through various media channels. Key informants added suggestions about interpersonal strategies (e.g., physician referrals) for center usage promotion but cautioned that a large increase in traffic could not be accommodated without increasing staff size or shifting from a model of individualized service. Conclusions: Triangulating findings from multiple data collection methods can provide useful guidance for efforts to promote center utilization. At minimum, steps should be taken to make the largest centers more noticeable. Because center utilization is not only associated with consumer satisfaction with hospitals, but may also foster health literacy, both hospital-based and community-based usage promotion strategies may be warranted. All such promotional strategies should be audience-tested before they are adopted. PMID:18219380

  12. From STEM to STEAM: Toward a Human-Centered Education

    Boy, Guy A.

    2013-01-01

    The 20th century was based on local linear engineering of complicated systems. We made cars, airplanes and chemical plants for example. The 21st century has opened a new basis for holistic non-linear design of complex systems, such as the Internet, air traffic management and nanotechnologies. Complexity, interconnectivity, interaction and communication are major attributes of our evolving society. But, more interestingly, we have started to understand that chaos theories may be more important than reductionism, to better understand and thrive on our planet. Systems need to be investigated and tested as wholes, which requires a cross-disciplinary approach and new conceptual principles and tools. Consequently, schools cannot continue to teach isolated disciplines based on simple reductionism. Science; Technology, Engineering, and Mathematics (STEM) should be integrated together with the Arts1 to promote creativity together with rationalization, and move to STEAM (with an "A" for Arts). This new concept emphasizes the possibility of longer-term socio-technical futures instead of short-term financial predictions that currently lead to uncontrolled economies. Human-centered design (HCD) can contribute to improving STEAM education technologies, systems and practices. HCD not only provides tools and techniques to build useful and usable things, but also an integrated approach to learning by doing, expressing and critiquing, exploring possible futures, and understanding complex systems.

  13. Portal hypertensive biliopathy: A single center experience and literature review.

    Suárez, Vanessa; Puerta, Andrés; Santos, Luisa Fernanda; Pérez, Juan Manuel; Varón, Adriana; Botero, Rafael Claudino

    2013-03-27

    Portal hypertensive biliopathy (PHB) is characterized by anatomical and functional abnormalities of the intrahepatic, extrahepatic and pancreatic ducts, in patients with portal hypertension associated to extrahepatic portal vein obstruction and less frequently to cirrhosis. These morphological changes, consisting in dilatation and stenosis of the biliary tree, are due to extensive venous collaterals occurring in an attempt to decompress the portal venous blockage. It is usually asymptomatic until it progresses to more advanced stages with cholestasis, jaundice, biliary sludge, gallstones, cholangitis and finally biliary cirrhosis. Imaging modalities of the biliary tree such as Doppler ultrasound, computed tomography, magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography are essential to establish the diagnosis and the need of therapeutical interventions. Once the diagnosis is established, treatment with ursodesoxycholic acid seems to be beneficial. Decompression of the biliary tree to dilate, remove stones or implant biliary prosthesis by endoscopic or surgical procedures (hepato-yeyunostomy) usually resolves the cholestatic picture and prevents septic complications. The ideal treatment is the decompression of the portal system, with transjugular intrahepatic porto-systemic shunt or a surgical porto-systemic shunt. Unfortunately, few patients will be candidates for these procedures due to the extension of the thrombotic process. The purpose of this paper is to report the first 3 cases of PHB seen in a Colombian center and to review the literature. PMID:23556047

    Due to the large number of falls that occur in hospital settings, inpatient fall prevention is a topic of great interest to patients and health care providers. The use of electronic decision support that tailors fall prevention strategy to patient-specific risk factors, known as Fall T.I.P.S (Tailoring Interventions for Patient Safety), has proven to be an effective approach for decreasing hospital falls. A paper version of the Fall T.I.P.S toolkit was developed primarily for hospitals that do not have the resources to implement the electronic solution; however, more work is needed to optimize the effectiveness of the paper version of this tool. We examined the use of human factors techniques in the redesign of the existing paper fall prevention tool with the goal of increasing ease of use and decreasing inpatient falls. The inclusion of patients and clinical staff in the redesign of the existing tool was done to increase adoption of the tool and fall prevention best practices. The redesigned paper Fall T.I.P.S toolkit showcased a built in clinical decision support system and increased ease of use over the existing version. PMID:27184319

  15. Head and Neck Sarcomas: A Comprehensive Cancer Center Experience

    Margaret von Mehren

    2013-07-01

    Full Text Available Head/neck sarcomas are rare, accounting for about 1% of head/neck malignancies and 5% of sarcomas. Outcomes have historically been worse in this group, due to anatomic constraints leading to difficulty in completely excising tumors, with high rates of local recurrence. We retrospectively analyzed cases of head/neck soft tissue sarcomas (STS and osteogenic sarcomas managed in a multi-disciplinary setting at Fox Chase Cancer Center from 1999–2009 to describe clinicopathologic characteristics, treatment, outcomes, and prognostic factors for disease control and survival. Thirty patients with STS and seven patients with osteogenic sarcoma were identified. Most STS were high grade (23 and almost all were localized at presentation (28. Common histologies were synovial cell (6, rhabdomyosarcoma (5, angiosarcoma (4, liposarcoma (4 and leiomyosarcoma (3. The type of primary therapy and disease outcomes were analyzed. Cox proportional hazards regression analysis was performed to identify predictors of disease-free survival (DFS and overall survival (OS. The HR and 95% CI for Cox model and median DFS/OS analyzed by Kaplan-Meier curves were calculated.

  16. Outcome Determinants of Stroke in a Brazilian Primary Stroke Center

    2014-01-01

    Full Text Available Background. Stroke mortality in Brazil is one of the highest among Western countries. Nonetheless, stroke outcome determinants are still poorly known in this country. In this study we evaluate outcome determinants of stroke in a primary stroke center in São Paulo, Brazil. Methods. We evaluated demographic, clinical, and outcome data of patients with ischemic stroke (IS, transient ischemic attack (TIA, and intracerebral hemorrhage (ICH admitted at “Hospital Paulistano,” São Paulo, Brazil. In-hospital mortality and functional outcome determinants were assessed. Univariate and binary logistic regression analysis were performed. Results. Three hundred forty-one patients were included in the study, 52.2% being male with 66.8±15.7 years. The stroke type distribution was IS: 59.2%, TIA: 29.6%, and ICH: 11.1%. ICH was associated with greater severity and poorer functional outcome. The determinants of poorer functional outcome were higher NIHSS, lower Glasgow score, and lower oxygen saturation level. The most important mortality determinant was the presence of visual symptoms. Conclusions. The stroke mortality and stroke outcome determinants found in the present study do not remarkably differ from studies carried out in developed countries. Stroke prognosis studies are crucial to better understand the high burden of stroke in Brazil.

    Jopek, Tadeusz Jan

    2016-01-01

    Currently, the meteor shower part of Meteor Data Center database includes: 112 established showers, 563 in the working list, among them 36 have pro tempore status and 23 will be removed from the list. The list of shower complexes contains 25 groups, 3 have established status and 1 has pro tempore status. In the past three years, new meteor showers submitted to the MDC database were detected amongst meteors observed by CAMS stations (Cameras for Allsky Meteor Surveillance), meteors included in the EDMOND (European viDeo MeteOr Network Database), meteors collected by Japanese SonotaCo Network, meteors recorded in IMO (International Meteor Organization) database, amongst meteors observed by Croatian Meteor Network and meteors observed on the Southern Hemisphere by the SAAMER radar. During the XXIXth General Assembly of the IAU in Honolulu, Hawaii in 2015, the names of 18 showers were o?cially accepted and moved to the list of established showers.

  18. Pre-operative fasting - a patient centered approach.

    Hamid, Sana

    2014-01-01

    Prolonged pre-operative fasting can be an unpleasant experience and result in serious medical complications. The Royal College of Nursing guidelines state a minimum fasting period of six hours for food and two hours for clear fluids, prior to elective anaesthesia or sedation in healthy patients. We audited the Moorfields South Pre-operative Assessment Unit fasting instruction policy to ensure it is clear and in accordance with national guidelines. A questionnaire assessing the clarity and accuracy of fasting instructions and patient hydration was employed to survey patients undergoing elective anaesthesia or sedation in July 2013 (first cycle) and September 2013 (second cycle). The fasting instruction policy and patient information leaflet were reviewed; they state "nothing to eat or drink from midnight" for morning surgery and "nothing to eat or drink from 7AM" for afternoon surgery. The 10 patients surveyed in the first cycle reported that the instructions they were given were clear. 70% expressed subjective dehydration and 40% showed clinical evidence of dehydration. The patients had not been encouraged to drink clear fluids up till two hours before surgery. Patients fasted for unnecessarily prolonged periods, the longest of which was 17 hours. Our interventions were: delivering a teaching session to update staff of current pre-operative fasting guidelines, producing a patient information leaflet that was correct, reader-friendly and comprehensive and displaying posters as a reminder of the updated fasting instruction policy. The 12 patients surveyed in the second cycle had been encouraged to drink clear fluids up till two hours before surgery. A dramatically reduced 25% expressed subjective dehydration and 25% showed clinical evidence of dehydration. The longest fasting period was reduced to eight hours. We encourage all hospitals to adopt a patient centered approach to pre-operative fasting, dispelling the "nil my mouth for eight hours" policy, to improve

    Raheem OA, Kamel MH, Daly PJ, Mohan P, Little DM, Awan A, Hickey DP. Mycophenolate mofetil in pediatric renal transplantation: A single center experience. Pediatr Transplantation 2011: 15:240-244. © 2009 John Wiley & Sons A\\/S. Abstract:  We assessed our long-term experience with regards to the safety and efficacy of MMF in our pediatric renal transplant population and compared it retrospectively to our previous non-MMF immunosuppressive regimen. Forty-seven pediatric renal transplants received MMF as part of their immunosuppressive protocol in the period from January 1997 till October 2006 (MMF group). A previously reported non-MMF group of 59 pediatric renal transplants was included for comparative analysis (non-MMF group). The MMF group comprised 29 boys and 18 girls, whereas the non-MMF group comprised 34 boys and 25 girls. Mean age was 11.7 and 12 yr in the MMF and non-MMF groups, respectively. The incidence of acute rejection episodes was 11 (23.4%) and 14 (24%) in the MMF and non-MMF group, respectively. Two (3.3%) grafts were lost in the non-MMF group compared with one (2.1%) in the MMF group. Twenty-one (44.68%) patients in the MMF group developed post-transplant infections compared with 12 (20.33%) in the non-MMF group (p < 0.0001). In conclusion, the use of MMF in pediatric renal transplantation was not associated with a lower rejection rate or immunological graft loss. It did, however, result in a significantly higher rate of viral infections.

  20. A project-centered undergraduate geoscience curriculum model

    Kelso, P.; Brown, L.

    2003-04-01

    Lake Superior State University, a comprehensive rural public university with approximately 10% Native-Americans enrolled, located in Michigan's eastern Upper Peninsula, U.S.A., has redesigned it's undergraduate geology major by developing an entire curriculum around a project-centered integration of geoscience sub-disciplines. Our model, adapted from modern educational theory, advocates sub-discipline integration by implementing problem-based learning through coursework that develops students' intellectual skills and engages them in using complex reasoning in real-world contexts. Students in this new curriculum will actively discover how to learn about a new geologic province, what questions to ask in approaching problems, where and how to find answers, and how to apply knowledge to solving problems. To accomplish our goals, we redesigned our pedagogy for all courses by creating active learning environments including cooperative learning, jigsaw methodologies, debates, investigation oriented laboratories, use of case studies, writing and communication intensive exercises, and research experiences. Fundamental sub-discipline concepts were identified by our national survey and are presented in the context of sequentially ordered problems that reflect increasing geological complexity. All courses above first year incorporate significant field experience. Our lower division courses include a two semester sequence of physical and historical geology in which physical processes are discussed in the context of their historical extension and one semester of structure/tectonics and mineralogy/petrology. The lower division culminates with a three week introductory field geology course. Our upper division courses include hydrologic systems, environmental systems, geochemical systems, tectonic systems, geophysical systems, clastic systems, carbonate systems, two seminar courses, and advanced field geology. The two field courses, offered in different geologic provinces, provide

  1. The ESRC: A Web-based Environmental Satellite Resource Center

    Abshire, W. E.; Guarente, B.; Dills, P. N.

    2009-12-01

    The COMET® Program has developed an Environmental Satellite Resource Center (known as the ESRC), a searchable, database-driven Website that provides easy access to a wide range of useful information training materials on polar-orbiting and geostationary satellites. Primarily sponsored by the NPOESS Program and NOAA, the ESRC is a tool for users seeking reliable sources of satellite information, training, and data. First published in September 2008, and upgraded in April 2009, the site is freely available at: http://www.meted.ucar.edu/esrc. Additional contributions to the ESRC are sought and made on an ongoing basis. The ESRC was created in response to a broad community request first made in May 2006. The COMET Program was asked to develop the site to consolidate and simplify access to reliable, current, and diverse information, training materials, and data associated with environmental satellites. The ESRC currently includes over 400 significant resources from NRL, CIMSS, CIRA, NASA, VISIT, NESDIS, and EUMETSAT, and improves access to the numerous satellite resources available from COMET’s MetEd Website. The ESRC is designed as a community site where organizations and individuals around the globe can easily submit their resources via online forms by providing a small set of metadata. The ESRC supports languages other than English and multi-lingual character sets have been tested. COMET’s role is threefold: 1) maintain the site, 2) populate it with our own materials, including smaller, focused learning objects derived from our larger training modules, and 3) provide the necessary quality assurance and monitoring to ensure that all resources are appropriate and well described before being made available. Our presentation will demonstrate many of the features and functionality of searching for resources using the ESRC, and will outline the steps for users to make their own submissions. For the site to reach its full potential, submissions representing diverse

  2. A Dirichlet process mixture model for survival outcome data: assessing nationwide kidney transplant centers.

    Zhao, Lili; Shi, Jingchunzi; Shearon, Tempie H; Li, Yi

    2015-04-15

    Mortality rates are probably the most important indicator for the performance of kidney transplant centers. Motivated by the national evaluation of mortality rates at kidney transplant centers in the USA, we seek to categorize the transplant centers based on the mortality outcome. We describe a Dirichlet process model and a Dirichlet process mixture model with a half-cauchy prior for the estimation of the risk-adjusted effects of the transplant centers, with strategies for improving the model performance, interpretability, and classification ability. We derive statistical measures and create graphical tools to rate transplant centers and identify outlying groups of centers with exceptionally good or poor performance. The proposed method was evaluated through simulation and then applied to assess kidney transplant centers from a national organ failure registry. PMID:25620744

    Choochaisri, Supasate; Jenjaturong, Saran; Intanagonwiwat, Chalermek; Ratanamahatana, Chotirat Ann

    2011-01-01

    In recent years, efficient energy utilization becomes an essential requirement for data centers, especially in data centers of world-leading companies, where "Green Data Center" defines a new term for an environment-concerned data center. Solutions to change existing a data center to the green one may vary. In the big company, high-cost approaches including re-planning server rooms, changing air-conditioners, buying low-powered servers, and equipping sophisticating environmental control equipments are possible, but not for small to medium enterprises (SMEs) and academic sectors which have limited budget. In this paper, we propose a novel system, SENVM, used to monitor and control air temperature in a server room to be in appropriate condition, not too cold, where very unnecessary cooling leads to unnecessary extra electricity expenses, and also inefficient in energy utilization. With implementing on an emerging technology, Wireless Sensor Network (WSN), Green Data Center is feasible to every small data center...

    2016-01-01

    Full Text Available Background and Objectives: Incidence of hospital-acquired diarrhea has increased rapidly and burn patients are at high risk of getting it. Infection with C. difficile is the most common cause of antibiotic associated diarrhea. The aim of this study was to determine the baseline characteristics and clinical presentation of hospital-acquired diarrhea and compare C. difficile and non-C. difficile diarrhea in burn patients treated at a burn center.Materials and Methods: During a 1-year study all patients with hospital-acquired diarrhea at Motahari Burn Hospital, Teh- ran, Iran enrolled in this study. We compared patients with a stool sample positive for C. difficile toxin or tracing the antigen in patients who were negative for detection of toxin in their stool sample specimens.Results: Diarrhea developed in 37 patients out of 3200 admitted patients with a mean burn size of 34.8 ±20.1%. Among them, 8 patients had a positive result for C. difficile. The mean time between antibiotic therapy and occurrence of diarrhea was 9.5 ± 6.2 days. Nine (23.7% patients died in the 7.8± 4.2 days, mostly due to co-morbidities. The mean duration of di- arrhea was 3.6 ± 2 days. Twenty two (57.9% patients were treated with oral metronidazol and eleven (28.9% patients were treated with combination of metronidazole and vancomycin, higher rate of combination therapy was seen in Clostridium difficile CDI.Conclusion: Overall, the prevalence of hospital-acquired diarrhea was 120/10,000  and 21% of them caused by infection with C. difficile. Presence of peripheral leukocytosis and colitis were the alarm sign for diagnosis of C. difficile infection. Keywords: Hospital-acquired diarrhea (HAD, Burn, Clostridium difficile infection (CDI

  5. Incidence of occupational exposures in a tertiary health care center

    Amrita Shriyan

    2012-01-01

    Full Text Available Introduction: Occupational exposure to Hepatitis B virus (HBV, human immunodeficiency virus (HIV and Hepatitis C virus (HCV infection is a cause of concern to all health care workers (HCWs, especially those, in hospitals. Among the HCWs, nurses, interns, technicians, resident doctors and housekeeping staff have the highest incidence of occupational exposure. Aims: To analyze the cases of needle stick injuries and other exposures to patient′s blood or body fluids among health care workers. Materials and Methods: A detailed account of the exposure is documented which includes incidence of needle stick injuries (NSI and implementation of post-exposure prophylaxis (PEP as per the hospital guidelines. We report a two-year continuing surveillance study where 255 health care workers (HCWs were included. PEP was given to HCWs sustaining NSI or exposures to blood and body fluids when the source is known sero-positive or even unknown where the risk of transmission is high. Follow-up of these HCW′s was done after three and six months of exposure. Results: Of the 255 HCWs, 59 sustained needle stick injuries and two were exposed to splashes. 31 of the NSI were from known sources and 28 from unknown sources. From known sources, thirteen were seropositive; seven for HIV, three for HCV and three for HBV. Nineteen of them sustained needle stick during needle re-capping, six of them during clean up, six of them while discarding into the container, 17 during administration of injection, eight of them during suturing, two occurred in restless patient, 17 during needle disposal. Conclusion: So far, no case of sero-conversion as a result of needle stick injuries was reported at our center.

  6. Invite, listen, and summarize: a patient-centered communication technique.

    Boyle, Dennis; Dwinnell, Brian; Platt, Frederic

    2005-01-01

    The need for physicians to have patient-centered communication skills is reflected in the educational objectives of numerous medical schools' curricula and in the competencies required by groups such as the Accreditation Council for Graduate Medical Education. An innovative method for teaching communications skills has been developed at the University of Colorado School of Medicine as part of its three-year, longitudinal course focusing on basic clinical skills required of all physicians. The method emphasizes techniques of open-ended inquiry, empathy, and engagement to gather data. Students refer to the method as ILS, or Invite, Listen, and Summarize. ILS was developed to combat the high-physician-control interview techniques, characterized by a series of "yes" or "no" questions. The authors began teaching the ILS approach in 2001 as one basic exercise and have since developed a two-year longitudinal communications curriculum. ILS is easy to use and remember, and it emphasizes techniques that have been shown in other studies to achieve the three basic functions of the medical interview: creating rapport, collecting good data, and improving compliance. The skills are taught using standardized patients in a series of four small-group exercises. Videotaped standardized patient encounters are used to evaluate the students. Tutors come from a variety of disciplines and receive standardized training. The curriculum has been well received. Despite the fact that the formal curriculum only occurs in the first two years, there is some evidence that it is improving students' interviewing skills at the end of their third year.

  15. A 10-year review of four academic nurse-managed centers: challenges and survival strategies.

    King, Eunice S

    2008-01-01

    Since 1985, there has been rapid growth in nurse-managed health centers (NMHCs). Many were established by academic schools of nursing, and several have closed. The Independence Foundation undertook this study to identify the challenges and survival strategies employed by four academic nurse-managed center grantees during a 10-year period. Data from Foundation records, interviews with directors and staff from the centers and the National Nursing Centers Consortium, a focus group with center founders, and field notes were analyzed for themes related to the centers' challenges and survival strategies. Although the centers faced many challenges from the sociopolitical environment, the community, and their parent organizations, the most difficult challenge was achieving financial sustainability, which was attainable only by obtaining cost-based reimbursement. Because of existing health policies, that was possible only through organizational restructuring and affiliation with an existing federally qualified health center. The future of nursing centers depends upon favorable health policies, data documenting centers' effectiveness, and adequate preparation of the next generation of nursing center directors and practitioners.

  1. Ethylene, a Hormone at the Center-Stage of Nodulation.

    Guinel, Frédérique C

    2015-01-01

    Nodulation is the result of a beneficial interaction between legumes and rhizobia. It is a sophisticated process leading to nutrient exchange between the two types of symbionts. In this association, within a nodule, the rhizobia, using energy provided as photosynthates, fix atmospheric nitrogen and convert it to ammonium which is available to the plant. Nodulation is recognized as an essential process in nitrogen cycling and legume crops are known to enrich agricultural soils in nitrogenous compounds. Furthermore, as they are rich in nitrogen, legumes are considered important as staple foods for humans and fodder for animals. To tightly control this association and keep it mutualistic, the plant uses several means, including hormones. The hormone ethylene has been known as a negative regulator of nodulation for almost four decades. Since then, much progress has been made in the understanding of both the ethylene signaling pathway and the nodulation process. Here I have taken a large view, using recently obtained knowledge, to describe in some detail the major stages of the process. I have not only reviewed the steps most commonly covered (the common signaling transduction pathway, and the epidermal and cortical programs), but I have also looked into steps less understood (the pre-infection step with the plant defense response, the bacterial release and the formation of the symbiosome, and nodule functioning and senescence). After a succinct review of the ethylene signaling pathway, I have used the knowledge obtained from nodulation- and ethylene-related mutants to paint a more complete picture of the role played by the hormone in nodule organogenesis, functioning, and senescence. It transpires that ethylene is at the center of this effective symbiosis. It has not only been involved in most of the steps leading to a mature nodule, but it has also been implicated in host immunity and nodule senescence. It is likely responsible for the activation of other hormonal

    2010-01-01

    BACKGROUND: Endoscopic retrograde cholangiopancreato-graphy (ERCP) is the ifrst choice for diagnostic evaluation of the pancreatic and biliary tree and can be accompanied by a high diagnostic sensitivity and a poor therapeutic outcome. In the current study, we described our experiences in the indications, ifndings, and technical success of ERCP in a sample of the Iranian population admitted to a referral center in Iran. METHODS: In a retrospective review database-based study, 780 patients (393 males and 387 females;mean age 57.5 years) who had undergone diagnostic and therapeutic ERCP with the primary diagnosis of hepatobiliary disorder between 2006 and 2008 at Taleghani Hospital in Tehran were reviewed. The key data were demographic characteristics, clinical information, laboratory parameters, as well as post-ERCP complications. RESULTS: A history of cholecystectomy was found in about one-third (36.3%) of participants and 80 (10.3%) out of 780 patients had a previous history of biliary stone. A minority (1.4%) of the patients suffered from hepatobiliary carcinomas, and 11 patients had cirrhosis. The most common clinical manifestations in the patients undergoing diagnostic ERCP were icterus (47.3%), weight loss (31.2%), and dark urine (26.9%). Selective biliary cannulation was technically successful in 87.0% of the patients; however, cannulation failed in 13.0%. The most frequent ifnal diagnosis of ERCP was common bile duct stone that was detected in 40.1% of the patients. The ERCP results in 11.0%of the patients were normal. Regarding appropriate treatment, successful stenting was performed in 43 patients (15.2%). Among post-ERCP complications, pancreatitis was the most adverse event with an incidence rate of 3.3%. Other complications including local bleeding, cholangitis and gastrointestinal perforation, rarely occurred. Post-ERCP pancreatitis was reported in 1.8%of men and 3.6%of women (P=0.120). Pancreatitis was more common in women below 70 years than

  7. Analysis of shielding for a proton therapy center

    An analysis of radiation shielding and radiation protection was made for the Czech proton therapy center project. The major sources of radiation were identified with focus on the dominant neutron component. The angular-energy distributions of secondary particles were modelled for proton beam interactions with selected materials within the proton beam energy range considered. The MCNPX Monte Carlo code and Bertini/ISABEL hadron interaction model were used. The angular-energy neutron spectrum was used to estimate the annual dose equivalent from selected secondary particle sources at the proton center. The dose equivalents were in turn used to verify the adequacy of the dimensions of the shielding structures/barriers (concrete wall and backfill soil) outside the cyclotron room. The influence of selection of the high-energy particle interaction models is discussed

  12. Texas A&M University Industrial Assessment Center Final Report

    Heffington, Warren M.; Eggebrecht, James A.

    2007-02-24

    This project benefited the public by assisting manufacturing plants in the United States to save costly energy resources and become more profitable. Energy equivalent to over 75,000 barrels of oil was conserved. The Texas A&M University Industrial Assessment Center (IAC) visited 96 manufacturing plants and spent 101 days in those plants during the contract period from August 9, 2002, through November 30, 2006. Recommended annual energy savings for manufacturers were 37,400,000 kWh (127,600 MMBtu—site basis) of electricity and 309,000 MCF (309,000 MMBtu) of natural gas. Each manufacturer subsequently was surveyed, and based on these surveys reportedly implemented 79% of the electricity savings and 36% of the natural gas savings for an overall energy savings of 48% of recommended. Almost 800 (798) projects were recommended to manufacturers, and they accomplished two-thirds of the projects. Cost savings recommended were $12.3 million and implemented savings were $5.7 million or 47%. During the contract period our average time between site visit and report submittal averaged 46 days; and decreased from 48 days in 2003 to 44 days in 2006. Serving clients well and promptly has been a priority. We visited five ESA overflow clients during FY 06. The Texas A&M University IAC pioneered the presentation of air pollution information in reports, and includes NOx and CO2 reductions due to energy savings in all reports. We also experimented with formal PowerPoint BestPractices presentations called Lunchtime/Showtime in each plant and with delivering electronic versions of the report. During the period of the contract, the director served on the Texas Industries of the Future (IOF) Refining and Chemicals Committee, which oversaw the showcases in 2003 and 2006. The assistant director was the Executive Director of the International Energy Technology Conference held annually. The director and assistant director became qualified specialists in the Process Heating Assessment Scoping

  14. Electron tunneling between two electrodes mediated by a molecular wire containing a redox center

    Graphical abstract: We present a model for a molecular wire containing a redox center and suspended in an electrolyte solution. Current potential curves can contain plateaus and negative differential resistances. - Abstract: We derive an explicit expression for the quantum conductivity of a molecular wire containing a redox center, which is embedded in an electrochemical environment. The redox center interacts with the solvent, and the average over the solvent configurations is performed numerically. Explicit calculations have been performed for a chain of three atoms. When the redox center interacts strongly with neighboring electronic levels, the current-potential curves show interesting features like rectification, current plateaus and negative differential resistance. Electronic spectroscopy of intermediate states can be performed at constant small bias by varying the electrochemical potential of the wire.

  18. A System for Scripted Data Analysis at Remote Data Centers

    Wang, D. L.; Zender, C. S.; Jenks, S. F.

    2007-12-01

    Terascale data reduction and analysis still remain elusive for most geoscientists even as large scale geophysical models and observing systems begin to produce petascale datasets. Massive amounts of geophysical netCDF data remain underutilized due to scientists' limited bandwidth and computational capacity. Compounding the problem are the unique characteristics of geoscientists' data analyses which are poorly matched to traditional grid technologies. Our system, the Script Workflow Analysis for MultiProcessing (SWAMP) allows scientists to efficiently leverage grid resources for parallel computation through a rich scripting syntax compatible with most existing analysis scripts. Although shell script languages are impossible to optimize for all cases, data analysis scripting is well-defined sufficiently to allow inference of dependencies and use of advanced compilation techniques. SWAMP compiles scripts to detect potential parallelism and to dynamically schedule for parallel execution on resources allocated by an industry-standard grid scheduling engine. By its unique focus on I/O and bandwidth considerations rather than raw computational power, our system more efficiently handles the characteristic I/O-boundedness of geoscience workflows. Although scientists' scripts exhibit significant available parallelism, such parallelism is poorly exploited by conventional means that manage I/O and data locality as afterthoughts, if at all. In contrast, SWAMP eliminates unnecessary data movement to achieve its parallel efficiency in two ways: by providing a computational interface integrated with data service, and by scheduling computation to avoid I/O bottlenecks in disks and networks. This efficiency and performance is designed to integrate with scientists' analysis scripts-- many existing scripts require no modification to work with SWAMP. We test our system in uniprocessor, multiprocessor, and clustered environments, with both simple and terascale test cases. Benchmarks and

  3. A community-oriented center for severely and profoundly retarded children.

    1975-10-01

    A center established three years ago to provide local residential services for severely and profoundly retarded children has developed programs that give the residents a high level of interaction with direct-care staff members and with the community. At the Elisabeth Ludeman Center, children live in groups of eight or fewer in four-bedroom homes served by neighborhood centers. In various community-oriented programs, high school students are trained for jobs as half-time technicians. Ludeman residents are placed half days in a community development center, part-time services are provided at Ludeman for clients of other agencies, and community members come to the center as volunteer instructors or as users of Ludeman facilities. A key part of the center's program is an audiovisual service used extensively for inservice training and staff communication. PMID:53179

Antiretroviral (ARV) agents are commonly prescribed drugs known to cause toxicity, yet the frequency of these incidents is unknown. The objectives of this study were to quantify the number of reported cases of toxicity secondary to ARV agents at a region...

  10. Acute Renal Failure in a Renal Center, Iraq

    We evaluated retrospectively the etiology and outcome of acute renal failure (ARF) in 84 patients in Rasheed Renal Center in Baghdad, Iraq from June 1998 through March 1999. They were 82 males and 2 females with ages that ranged between 5 and 80 years. Prerenal ARF was the commonest type found in 45 (53.6%) patients followed by renal ARF in 33 (39.3%) patients and acute obstructive uropathy six (7.1%) patients. Clinically, 74 patients presented with oligo-anuria, while 10 patients presented with non-oliguria. Of the oligo-anuria group, 61 ( 82.4%) patients required required renal replacement therapy (RRT) and 50 (67.6%) had complete recovery. The mortality rate was 25.67% in the oliguric group, while none in the non-oliguric group required RRT and the complete recvery rate was 100%. The overall survival in both groups was (77.4%). The patterns of ARF in our center were mostly compatible with the previous reports from the region. (author)

  15. A mathematical model for the germinal center morphology and affinity maturation

    Meyer-Hermann, M

    2002-01-01

    During germinal center reactions the appearance of two specific zones is observed: the dark and the light zone. Up to now, the origin and function of these zones are poorly understood. In the framework of a stochastic and discrete model several possible pathways of zone development during germinal center reactions are investigated. The importance of the zones in the germinal center for affinity maturation, i.e. the process of antibody optimization is discussed.

    Zalenski, R J; Rydman, R J; Ting, S; Kampe, L; Selker, H P

    1998-06-01

    Although chest pain centers are promoted as improving emergency cardiac care, no data exist on their structure and processes. This national study determines the 1995 prevalence rate for emergency department (ED)-based chest pain centers in the United States and compares organizational differences of EDs with and without such centers. A mail survey was directed to 476 EDs randomly selected from the American Hospital Association's database of metropolitan hospitals (n = 2,309); the response rate was 63%. The prevalence of chest pain centers was 22.5% (95% confidence interval 18% to 27%), which yielded a projection of 520 centers in the United States in 1995. EDs with centers had higher overall patient volumes, greater use of high-technology testing, lower treatment times for thrombolytic therapy, and more advertising (all p <0.05). Hospitals with centers had greater market competition and more beds per annual admissions, cardiac catheterization, and open heart surgery capability (all p <0.05). Logistic regression identified open heart surgery, high-admission volumes, and nonprofit status as independent predictors of hospitals having chest pain centers. Thus, chest pain centers have a moderate prevalence, offer more services and marketing efforts than standard EDs, and tend to be hosted by large nonprofit hospitals. PMID:9631967

  2. Asymmetric transmission through a flux-controlled non-Hermitian scattering center

    Li, X. Q.; Zhang, X. Z.; Zhang, G.; Song, Z.

    2015-03-01

    We study the possibility of asymmetric transmission induced by a non-Hermitian scattering center embedded in a one-dimensional waveguide, motivated by the aim of realizing quantum diodes in a non-Hermitian system. It is shown that a PT -symmetric non-Hermitian scattering center always has symmetric transmission although the dynamics within the isolated center can be unidirectional, especially at its exceptional point. We propose a concrete scheme based on a flux-controlled non-Hermitian scattering center, which comprises a non-Hermitian triangular ring threaded by an Aharonov-Bohm flux. The analytical solution shows that such a complex scattering center acts as a diode at the resonant energy level of the spectral singularity, exhibiting perfect unidirectionality of the transmission. The connections between the phenomena of the asymmetric transmission and reflectionless absorption are also discussed.

  3. Senior Centers and Nutritional Outcomes: A Texas Example.

    Swan, James H; Severance, Jennifer J; Turner, Keith

    2016-01-01

    Healthy diet and weight control are important for elders and senior centers (SCs). The authors consider effects of SCs on attendee nutrition and health and efforts to improve diets and weight. Data derive from surveys in 2006 (N = 798) and 2007 (N = 742) at 21 multipurpose SCs in Tarrant County, Texas, supplemented with data from 2012 (N = 1,402). Measures included attendee agreement that SC meals improved nutrition, improved health, attempts to improve diets, and success in controlling weight. Cumulative and binary logistic regression methods were employed. SC attendance and social engagement explained agreement that SC meals improved nutrition and health but were not shown to predict changes in diet or weight control. Findings suggest success of SC programs, as well as physician recommendations, in influencing attendee nutritional behavior and perceptions of nutrition and health effects. Practice recommendations include SC collaborations with local health providers to promote attendee nutritional health. PMID:27191952

    T Azizi

    2009-01-01

    Full Text Available Background: Osteosarcomas (OS of the jaws are uncommon lesions representing 6-8% of skeletal OS. We assessed the characteristics, demographics, prevalence clinical and histopathological findings and distribution of gnathic OS relative to non-gnathic OS in four major treatment centers. Materials and Methods: This study assessed 13 gnathic OS patients of 98 OS patients from four major referral centers during 1996-2007. The age distribution, gender, involved site, clinical findings, signs, symptoms, grade and sub-types were assessed. Hematoxylin-eosin, Picrosirius red, Ponceau trichrome, Masson trichrome and osteoid staining methods were used. Results: Of the 98 OS lesions, 85 (86.8% involved the skeleton, the youngest patient was 6 and the oldest 60 years old; 13 lesions (13.2% involved the jaws (seven mandibular and six maxillary and the youngest and oldest patients were 15 and 50 years-old, respectively. Non-gnathic OS was more prevalent between the ages of 11 and 20 years (avg. 15 years and was common in the distal femur and proximal tibia, presenting most frequently with pain and swelling. OS of the jaws, however, presented more than 10 years later than non-gnathic OS, being more prevalent between the ages of 20 and 30 years (avg. 27 years. OS of the jaws most frequently involved the mandibular body and the posterior maxillary alveolar ridge, presenting frequently with pain, swelling and loosening of teeth. Two patients with gnathic OS died during the 10-year follow-up period (15.3%. Conclusion: Prevalence of OS of the jaws was about twice as high as that reported in other studies and presented later than non-gnathic cases. Pain and swelling were common signs and symptoms in this disease. The mixed sub-type was the most common sub-type of gnathic OS.

  6. A simulation based decision support system for a health promotion center.

    Hatcher, M; Rao, N

    1988-02-01

    This study represents the financial and qualitative evaluation of a Health Promotion Center of a private hospital located in a medium-sized town located in a predominantly agricultural area. The major objective of this study was to evaluate the impact of various pricing, advertising, and service strategies on profitability. The result is a pricing strategy which allows the center to reach their financial goal of breaking even while maintaining their service policies. The hospital, which serves a community of 500,000 people, recently developed a new concept called a "Health Promotion Center" (HPC). The HPC provides services such as fitness programs, nutrition awareness, rehabilitation and therapy, and child and adult care. For this purpose, a new building was constructed and the center became operational in June 1983. A variety of management options available to the center are described with evaluations of their usefulness. Evaluation methods include scenarios, stochastic simulations, and analyses of how the decision makers use these methods. The inclusion of risk management, model flexibility, and user involvement are stressed throughout the paper and are critical in the decision process. PMID:3294327

  8. Optical determination and magnetic manipulation of a single nitrogen-vacancy color center in diamond nanocrystal

    The controlled and coherent manipulation of individual quantum systems is fundamental for the development of quantum information processing. The nitrogen-vacancy (NV) color center in diamond is a promising system since its photoluminescence is perfectly stable at room temperature and its electron spin can be optically read out at the individual level. We review here the experiments currently realized in our laboratory concerning the use of a single NV color center as the single photon source and the coherent magnetic manipulation of the electron spin associated with a single NV color center. Furthermore, we demonstrate a nanoscopy experiment based on the saturation absorption effect, which allows to optically pin-point a single NV color center at sub-λ resolution. This offers the possibility to independently address two or multiple magnetically coupled single NV color centers, which is a necessary step towards the realization of a diamond-based quantum computer

  16. A descriptive survey of management and operations at selected sports medicine centers in the United States.

    Olsen, D

    1996-11-01

    No uniform guidelines for operations or accreditation standards for sports medicine center were available and, at the time of this study, little information on the management and operation of sports medicine centers was available in the literature. The purpose of the study was to determine the management structure and function of selected sports medicine centers in the United States. Questionnaires were mailed to 200 randomly selected centers throughout the United State from a directory of sports medicine centers published in Physician and Sportsmedicine (1992) to gather descriptive information on eight areas, including 1) general background, 2) staffing, 3) services, facilities, and equipment, 4) billing, collections, and revenue, 5) clientele, caseloads, and referrals, 6) ownership and financing, 7) school and club outreach contracts, and 8) marketing strategies and future trends. A total of 71 surveys (35.5%) were returned in the allotted time frame. Data were analyzed using ranges, means, medians, modes, and percentages. Results yielded several conclusions about sports medicine centers. Nearly all (93%) of the centers employed physical therapists; physical therapists were clinical directors at 70.2% of centers; orthopaedists were most often medical directors; rehabilitation was the most frequently offered service (93%); physical therapy produced the highest revenue; sports injuries accounted for a mean 34.5% of patients, who were mostly recreational or high school athletes between 13-60 years of age; primary shareholders were most often physical therapists or physicians; most were involved in outreach services for schools; marketing strategies primarily involved communication with referral sources; and managed care was identified most frequently as a trend affecting the future of sports medicine centers. Findings identified common aspects of sports medicine centers and may assist in establishing guidelines for operations or accreditation of sports medicine

    2011-01-01

    We report on the controlled coupling of a single nitrogen-vacancy (NV) center to a surface plasmon mode propagating along a chemically grown silver nanowire (NW). We locate and optically characterize a single NV center in a uniform dielectric environment before we controllably position this emitter...... in the close proximity of the NW. We are thus able to control the coupling of this particular emitter to the NW and directly compare the photon emission properties before and after the coupling. The excitation of single plasmonic modes is witnessed and a total rate enhancement by a factor of up to 4...

  18. A Proposed Experiment to Study Relaxation Formation of a Spherical Tokamak with a Plasma Center Column

    Hsu, S C

    2006-01-01

    A spherical tokamak (ST) with a plasma center column (PCC) can be formed via driven magnetic relaxation of a screw pinch plasma. An ST-PCC could in principle eliminate many problems associated with a material center column, a key weakness of the ST reactor concept. This work summarizes the design space for an ST-PCC in terms of flux amplification, aspect ratio, and elongation, based on the zero-beta Taylor-relaxed analysis of Tang & Boozer [Phys. Plasmas 13, 042514 (2006)]. The paper will discuss (1) equilibrium and stability properties of the ST-PCC, (2) issues for an engineering design, and (3) key differences between the proposed ST-PCC and the ongoing Proto-Sphera effort in Italy.

  19. Acoustic centering of a baffled piston in the circular harmonics domain.

    Shabtai, Noam R; Vorländer, Michael

    2016-03-01

    The acoustic center of radiating sources is relevant to the modeling of radiation patterns and to their effective implementation in acoustical applications and computer models. However, the acoustic center of the sources may not be unique and therefore should be defined. Previously studied source centering algorithms used analytic methods for specific acoustic models, or applied post processing methods on a recorded sound from an acoustic source that was surrounded by a spherical microphone array. This work performs an acoustic centering of a radiating circular baffled piston that is formed by an open termination of a circular pipe. A signal processing based acoustic centering algorithm is redefined for this case and is shown to be correlated with the effective length of the pipe. PMID:27036274

    Sharath Asokan

    2014-01-01

    Aim: This study was planned to evaluate and validate a specially prepared questionnaire as a child behavior prediction scale. Design: A two-center cross-sectional study was done to validate the new scale. Materials and Methods: Children aged 3-12 years (n = 296, from two different centers participated in this study. The questionnaire used was a 10-point observational scale. Observations involved perceiving overt and subtle behavioral characteristics of a child, to assess the child′s behavior in the dental office before treatment. An independent observer approached the children and their parents in the waiting room. The child′s behavior was then evaluated by the dentist using Frankl behavior rating scale during and after treatment. The prediction of behavior compared to the Frankl scale was assessed and validated. Statistical Analysis: Sensitivity, specificity tests, and receiver operating curve analysis were used to validate the new scale and calculate the cut-off score for positive and negative behavior. All data were processed by SPSS software (16.0, SPSS Inc., Chicago, Ill, USA. Results: The best cut-off score to predict a positive Frankl rating was ≥ 8.0 in both the centers. The sensitivity and specificity scores were 93.4% and 62.5% in center 1; 83.1% and 59.6% in center 2 respectively. Conclusion: This novel prediction scale can be of great importance in predicting children′s behavior in the dental environment.

    The binding energy as well as the linear, third-order nonlinear and total optical absorption coefficient and refractive index changes of an off-center hydrogenic donor impurity in an InAs spherical quantum dot placed at the center of a GaAs cylindrical nano-wire have been investigated. In this regard, the effective-mass approximation approach is considered and eigenvalues and corresponding eigenfunctions are calculated via the finite element method. The binding energy is plotted as a function of the dot size and impurity position along with optical properties as a function of photon energy. In this study two different directions have been considered for impurity position, along the nano-wire axis and perpendicular to it. It has been found that the binding energy, absorption coefficient and refractive index changes are impressively affected not only by the dot radius but also by the position of the impurity and its direction. Additionally, the optical saturation can be tuned by the direction of the impurity and incident optical intensity. -- Highlights: • We consider spherical quantum dot located at the center of a cylindrical nano-wire. • An off-center hydrogenic donor impurity is considered in the system. • Binding energy is affected by orientation of impurity and its distance from center. • Saturation depends on the orientation of impurity position. • By shifting impurity position, orientation and dot radius blue- and red-shifts appear.

  4. Implementation of a user-centered framework in the development of a web-based health information database and call center.

    Taylor, Heather A; Sullivan, Dori; Mullen, Cydney; Johnson, Constance M

    2011-10-01

    As healthcare consumers increasingly turn to the World Wide Web (WWW) to obtain health information, it is imperative that health-related websites are user-centered. Websites are often developed without consideration of intended users' characteristics, literacy levels, preferences, and information goals resulting in user dissatisfaction, abandonment of the website, and ultimately the need for costly redesign. This paper provides a methodological review of a user-centered framework that incorporates best practices in literacy, information quality, and human-computer interface design and evaluation to guide the design and redesign process of a consumer health website. Following the description of the methods, a case analysis is presented, demonstrating the successful application of the model in the redesign of a consumer health information website with call center. Comparisons between the iterative revisions of the website showed improvements in usability, readability, and user satisfaction. PMID:21396486

  5. French Radiotherapy Database: Results of a survey of French radiation oncology centers in 2007

    The second year, the French Radiotherapy Database presents information from French radiation oncology centers. Among 179 centers, 159 have participated (90 %). The number of accelerators increased from 371 to 384 between 2006 and 2007, 11 % of these machines are more than 15 years old. On average, centers are open 50 hours per week for treatment and 9.5 % more for maintenance. The lack of dedicated CT remains a difficulty: 158 from 159 centers have an access to a CT, but only 50 % have a dedicated scanner. There is no progress compared to 2006. The proportion of centers having a MU double calculation system has increased from 51 to 58 %. Two thirds of centers do not implement in vivo dosimetry. The activity is stable around 190 000 treatments per year. Three-dimension conformal radiotherapy is used for more than half of treatments in 77.2 % of private centers and 50 % of public hospitals. Intensity modulated radiotherapy remains rarely used. The number of radiation oncologists and technologists remains stable. The number of radio physicists has increased from 7.6 %. Despite some progress, the difficulties of this speciality persist in France and are equally distributed across all regions, and between private and public centers. In 2009, the French Society for Radiation Oncology and the associated partners will continue this survey, which interest is recognized by both professionals and health administrations. (authors)

  12. A new approach for laboratory exercise of pathophysiology in China based on student-centered learning.

    Chen, Jian; Zhou, Junhai; Sun, Li; Wu, Qiuhui; Lu, Huiling; Tian, Jing

    2015-06-01

    Student-centered learning is generally defined as any instructional method that purportedly engages students in active learning and critical thinking. The student-centered method of teaching moves the focus from teaching to learning, from the teachers' conveying course concepts via lecture to the understanding of concepts by students. The student-centered method has been used extensively in lecture courses in China; however, there is little evidence of its use in laboratory courses. The purpose of the present study was to describe the implementation of a student-centered method in a pathophysiology laboratory course. The use of student-centered learning strategies in an undergraduate laboratory course was well received by both students and teachers. Here, students had to take on responsibility for their own learning and, thus, became more accountable. Moreover, they reported increased active learning, skill development, information collection, and retention. In addition, mean scores for the quiz were significantly higher in the student-centered method compared with the traditional teaching method. The shift from teacher-centered delivery to a student-centered model led to a positive change, in which the learners drove the process and were guided, not directed, by the teacher. PMID:26031728

    Kramer, Peter; Kramer, Tobias

    2014-01-01

    We present an extension of the spin-adapted configuration-interaction method for the computation of four electrons in a quasi two-dimensional quantum dot. By a group-theoretical decomposition of the basis set and working with relative and center-of-mass coordinates we obtain an analytical identification of all spurious center-of-mass states of the Coulomb-interacting electrons. We find a substantial reduction in the basis set used for numerical computations. At the same time we increase the a...

  1. First-principles calculation of the ultrafast spin manipulation of two-center metallic clusters with a CO molecule attached to one center as an infrared marker

    Li, Chun; Hartenstein, Tobias; Lefkidis, Georgios; Hübner, Wolfgang

    2009-05-01

    We present a fully ab initio ultrafast spin manipulation calculation in two-magnetic-center clusters with CO attached to one of the magnetic centers. CO serves as an experimental marker for certain magnetic states between which spin flip and transfer can be achieved. The predicted spin-state-dependent CO vibrational frequencies indicate that spin manipulation can be readily monitored through the infrared spectrum. The feasibility is demonstrated by two charged clusters [CoMg2Ni-CO]+ and [NiCo-CO]+ . Spin transfer between magnetic centers is achieved with a fidelity of 99.8%.

  2. Quantum Zeno effect in a nitrogen-vacancy center embedded in a spin bath

    Yang, Zhi-Sheng; Zhang, Mei; Ai, Qing; Deng, Fu-Guo

    2016-01-01

    We study the longitudinal relaxation of a nitrogen-vacancy (NV) center surrounded by a $^{13}$C nuclear spin bath in diamond. By means of cluster-correlation expansion (CCE), we numerically demonstrate the decay process of electronic state induced by cross relaxation at low temperature. It is shown that the CCE method is not only capable of describing pure-dephasing effect at large-detuning regime, but it can also simulate the quantum dynamics of populations in the nearly resonant regime. We present a proposal to slow down the decay of NV center via implementing quantum Zeno effect (QZE). The numerical result shows that QZE can effectively inhibit the decay of NV center.

    1999-03-01

    Once again, the most recent fiscal year was a productive one for the Carbon Dioxide Information Analysis Center (CDIAC) at Oak Ridge National Laboratory (ORNL), as well as a year for change. The FY 1998 in Review section in this report summarizes quite a few new and updated data and information products, and the ''What's Coming in FY 1999'' section describes our plans for this new fiscal year. During FY 1998, CDIAC began a data-management system for AmeriFlux, a long-term study of carbon fluxes between the terrestrial biosphere of the Western Hemisphere and the atmosphere. The specific objectives of AmeriFlux are to establish an infrastructure for guiding, collecting, synthesizing, and disseminating long-term measurements of CO{sub 2}, water, and energy exchange from a variety of ecosystems; collect critical new information to help define the current global CO{sub 2} budget; enable improved predictions of future concentrations of atmospheric CO{sub 2}; and enhance understanding of carbon fluxes. Net Ecosystem Production (NEP), and carbon sequestration in the terrestrial biosphere. The data-management system, available from CDIAC'S AmeriFlux home page (http://cdiac.esd.ornl.gov/programs/ameriflux/ ) is intended to provide consistent, quality-assured, and documented data across all AmeriFlux sites in the US, Canada, Costa Rica, and Brazil. It is being developed by Antoinette Brenkert and Tom Boden, with assistance from Susan Holladay (who joined CDIAC specifically to support the AmeriFlux data-management effort).

  6. Low-temperature'' behavior of a phase-slip center

    Yang, X.; Tidecks, R. (I. Physikalisches Institut der Universitaet Goettingen, Bunsenstrasse 9, D-3400 Goettingen, Federal Republic of Germany (DE))

    1991-05-27

    The differential resistance of the voltage-current characteristic generated by an isolated phase-slip center in a superconducting tin whisker has been measured down to 50 mK below its critical temperature. As a function of the temperature the differential resistance shows a resonancelike behavior with a maximum at the temperature where charge-imbalance waves excited by the phase-slip center have their maximum decay length, suggesting that the observed maximum of the differential resistance gives experimental evidence for charge-imbalance waves arising from a phase-slip center.

  17. Quantitative and qualitative assessment of structural magnetic resonance imaging data in a two-center study

    Multi-center magnetic resonance imaging (MRI) studies present an opportunity to advance research by pooling data. However, brain measurements derived from MR-images are susceptible to differences in MR-sequence parameters. It is therefore necessary to determine whether there is an interaction between the sequence parameters and the effect of interest, and to minimise any such interaction by careful choice of acquisition parameters. As an exemplar of the issues involved in multi-center studies, we present data from a study in which we aimed to optimize a set of volumetric MRI-protocols to define a protocol giving data that are consistent and reproducible across two centers and over time. Optimization was achieved based on data quality and quantitative measures, in our case using FreeSurfer and Voxel Based Morphometry approaches. Our approach consisted of a series of five comparisons. Firstly, a single-center dataset was collected, using a range of candidate pulse-sequences and parameters chosen on the basis of previous literature. Based on initial results, a number of minor changes were implemented to optimize the pulse-sequences, and a second single-center dataset was collected. FreeSurfer data quality measures were compared between datasets in order to determine the best performing sequence(s), which were taken forward to the next stage of testing. We subsequently acquired short-term and long-term two-center reproducibility data, and quantitative measures were again assessed to determine the protocol with the highest reproducibility across centers. Effects of a scanner software and hardware upgrade on the reproducibility of the protocols at one of the centers were also evaluated. Assessing the quality measures from the first two datasets allowed us to define artefact-free protocols, all with high image quality as assessed by FreeSurfer. Comparing the quantitative test and retest measures, we found high within-center reproducibility for all protocols, but lower

    The first international conference on the central region of our galaxy was held at UCLA during July 25-29, 1988. Radio, infrared, X-, and {gamma}-ray astronomers, benefitting from recent technological advances, confronted theorists, as well as each other, with impressive new imagery in each of these domains. Traditionally hidden by an impenetrable veil of dust, the galactic center is now largely transpasrent, particularly in the near-IR, where the extinction toward the galactic center is an order of magnitude less than at optical wavelengths. On the large scale, one observes a large reservoir of molecular gas, some of which is exhibiting complex, noncircular motions. Some of the kinematical behavior is best explained in terms of energetic explosions occurring about 10{sup 7} years ago. The radio continuum reveals numerous filaments of ionized gas, and strong, poloidal magnetic fields are implied, quite unlike the field anywhere else in the galaxy. On small scales, much effort is going into the attempt to identify a unique objedct at the nucleus that may or may not be a massive black hole (a mass of 3x10{sup 6} M{sub sun} has been defended). Candidates exist for a compact mass concentration, and for a strong central luminosity source, but they are not necessarily one and the same, and there are problems identifying any of the candidates with a massive accreting object at the center. Surrounding the dynamical center of the galaxy is the prominent radio source Sgr A, which includes a warm, turbulent circumnuclear disk on 5 to 10 pc scales, streamers of ionized gas which may represent flows of material into the central potential well, and a background shell of nonthermal radio emission, probably a superimposed supernova remnant. This summary describes some of the current research activity on the galactic center, with particular attention to the implications of X- and {gamma}-ray observations. (orig.).

  5. Role of the health center in health crisis management, especially in a radiation disaster

    In a disaster, in particular a radiation disaster, health centers should play an active role in taking advantage of its own expertise. There are various causes of a health crisis; the response to a health crisis is defined according to each cause. However, it should be adequately addressed by assuming the worst case for a health crisis of unknown cause. The role of health centers, in addition to the implementation of appropriate and timely treatment of any health crisis, is prevention of a future health crisis, advanced preparation, and damage recovery; activities during normal times are also important to maintain. Regarding the specific activities of the health center, judgment in the preference of measures to be performed is important. That the information is collected properly based on the idea of risk communication, coordination, and public relations transmission is required also for health centers. (author)

  7. A Blended Transfer and Communications Center: Designing a State-of-the-Art Mission Control.

    Morris, Melanie K; Carter, Kimberly F

    2015-01-01

    Health systems frequently are challenged by barriers to patient flow and transfer intake processes. To achieve the goals of seamless entry of patients into the health system, coordination of the safest, most appropriate transport of these patients, and efficient management of hospital throughput needs, our tertiary health system created a central transfer and communications center. From the design of the center's physical space to the collaborative education efforts, the immediate synergies created by this new "Mission Control" model impacted throughput and customer service. Achievement of these goals is facilitated with state-of-the-art technology, including an electronic throughput and flow software system, which provides real-time capacity updates and status of confirmed and pending discharges. Because a centralized, information-centered approach to coordination has been such a success, expansion to other departments is underway. We are also finding that our operations center is playing a more central role in emergency operations and disaster management logistics at both the local and regional levels. Centralization of key throughput components of health systems is quickly becoming best practice. Revenue savings can be gained by combining departmental resources as well as supporting throughput efficiencies. PMID:26340248

  9. Tri-layer wrinkling as a mechanism for anchoring center initiation in the developing cerebellum.

    Lejeune, Emma; Javili, Ali; Weickenmeier, Johannes; Kuhl, Ellen; Linder, Christian

    2016-07-01

    During cerebellar development, anchoring centers form at the base of each fissure and remain fixed in place while the rest of the cerebellum grows outward. Cerebellar foliation has been extensively studied; yet, the mechanisms that control anchoring center initiation and position remain insufficiently understood. Here we show that a tri-layer model can predict surface wrinkling as a potential mechanism to explain anchoring center initiation and position. Motivated by the cerebellar microstructure, we model the developing cerebellum as a tri-layer system with an external molecular layer and an internal granular layer of similar stiffness and a significantly softer intermediate Purkinje cell layer. Including a weak intermediate layer proves key to predicting surface morphogenesis, even at low stiffness contrasts between the top and bottom layers. The proposed tri-layer model provides insight into the hierarchical formation of anchoring centers and establishes an essential missing link between gene expression and evolution of shape.

  14. Human‐Centered Design: Integrating Services & Systems Around People By Providing A Common Ground for Action

    Junginger, Sabine

    2014-01-01

    both professional fields. Yet, how human‐centered design is being practiced and applied depends on the interpretation of the concept, or the “designer’s stance” (Buchanan 2011). In this paper, I trace the shifts in design thinking and the role of people in service engineering and in service design. I...... argue that human-centered design challenges the systems view of service engineers and service designers and requires them to reach out to each other. For this reason, I conclude that for these two disciplines, human-centered design provides a common ground for purposeful action: to arrive at the best...

  15. Quantum information transfer with nitrogen-vacancy centers coupled to a whispering-gallery microresonator

    Li, Pengbo

    2010-01-01

    We propose an efficient scheme for the realization of quantum information transfer and entanglement with nitrogen-vacancy (NV) centers coupled to a high-Q microspherical resonator. We show that, based on the effective dipole-dipole interaction between the NV centers mediated by the whispering-gallery mode (WGM), quantum information can be transferred between the NV centers through Raman transitions combined with laser fields. This protocol may open up promising possibilities for quantum communications with the solid state cavity QED system.

  20. A Modified Artificial Bee Colony Algorithm for p-Center Problems

    Alkın Yurtkuran

    2014-01-01

    Full Text Available The objective of the p-center problem is to locate p-centers on a network such that the maximum of the distances from each node to its nearest center is minimized. The artificial bee colony algorithm is a swarm-based meta-heuristic algorithm that mimics the foraging behavior of honey bee colonies. This study proposes a modified ABC algorithm that benefits from a variety of search strategies to balance exploration and exploitation. Moreover, random key-based coding schemes are used to solve the p-center problem effectively. The proposed algorithm is compared to state-of-the-art techniques using different benchmark problems, and computational results reveal that the proposed approach is very efficient.

    This research demonstrated the use of Remote Sensing technique and GIS to determine the suitability of an evacuation center. This study was conducted in Batu Pahat areas that always hit by a series of flood. The data of Digital Elevation Model (DEM) was obtained by ASTER database that has been used to delineate extract contour line and elevation. Landsat 8 image was used for classification purposes such as land use map. Remote Sensing incorporate with GIS techniques was used to determined the suitability location of the evacuation center from contour map of flood affected areas in Batu Pahat. GIS will calculate the elevation of the area and information about the country of the area, the road access and percentage of the affected area. The flood affected area map may provide the suitability of the flood evacuation center during the several levels of flood. The suitability of evacuation centers can be determined based on several criteria and the existing data of the evacuation center will be analysed. From the analysis among 16 evacuation center listed, there are only 8 evacuation center suitable for the usage during emergency situation. The suitability analysis was based on the location and the road access of the evacuation center toward the flood affected area. There are 10 new locations with suitable criteria of evacuation center proposed on the study area to facilitate the process of rescue and evacuating flood victims to much safer and suitable locations. The results of this study will help in decision making processes and indirectly will help organization such as fire-fighter and the Department of Social Welfare in their work. Thus, this study can contribute more towards the society.

    We show convergence of a cell-centered finite volume discretization for linear elasticity. The discretization, termed the MPSA method, was recently proposed in the context of geological applications, where cell-centered variables are often preferred. Our analysis utilizes a hybrid variational formulation, which has previously been used to analyze finite volume discretizations for the scalar diffusion equation. The current analysis deviates significantly from the previous in three respects. Fi...

  12. A novel scheme for global scattering center modeling of radar targets

    2008-01-01

    A novel scheme for extracting the global scattering center model of radar targets is proposed in this paper.The 2D/3D scattering center models can be recon structed based on the wideband measurements at different viewing angles.The sphere spreading of the 1D scattering center projections is exploited.The 1D-2D/3D scatterer map(OTSM)is designed to manifest the high dimensional scattering characteristic of radar targets.The Hough transform and the least squares method are used to extract the stable scattering centers and their scattering coefficients.This modeling method does not need a high density of the spatial grid,which greatly cuts down the necessary original data.The model built in this Way describes the stable point scattering mechanisms in a large spatial extent and can be extrapolated to other frequencies in the optical region.Examples verify the validity of both the model and the method.

  13. Vector magnetic field sensing by a single nitrogen vacancy center in diamond

    Chen, X.-D.; Sun, F.-W.; Zou, C.-L.; Cui, J.-M.; Zhou, L.-M.; Guo, G.-C.

    2013-03-01

    In this letter, we proposed and experimentally demonstrated a method to detect the vector magnetic field with a single nitrogen vacancy (NV) center in diamond. The magnetic field in parallel with the axis of the NV center can be obtained by detecting the electron Zeeman shift, while the Larmor precession of an ancillary nuclear spin close to the NV center can be used to measure the field perpendicular to the axis. Experimentally, both the Zeeman shift and Larmor precession can be measured through the fluorescence from the NV center. By applying additional calibrated magnetic fields, complete information on the vector magnetic field can be achieved with such a method. This vector magnetic-field detection method is insensitive to temperature fluctuation and it can be applied to nanoscale magnetic measurements.

  14. Audit of a Scientific Data Center for Certification as a Trustworthy Digital Repository: A Case Study

    Downs, R. R.; Chen, R. S.

    2011-12-01

    Services that preserve and enable future access to scientific data are necessary to ensure that the data that are being collected today will be available for use by future generations of scientists. Many data centers, archives, and other digital repositories are working to improve their ability to serve as long-term stewards of scientific data. Trust in sustainable data management and preservation capabilities of digital repositories can influence decisions to use these services to deposit or obtain scientific data. Building on the Open Archival Information System (OAIS) Reference Model developed by the Consultative Committee for Space Data Systems (CCSDS) and adopted by the International Organization for Standardization as ISO 14721:2003, new standards are being developed to improve long-term data management processes and documentation. The Draft Information Standard ISO/DIS 16363, "Space data and information transfer systems - Audit and certification of trustworthy digital repositories" offers the potential to evaluate digital repositories objectively in terms of their trustworthiness as long-term stewards of digital resources. In conjunction with this, the CCSDS and ISO are developing another draft standard for the auditing and certification process, ISO/DIS 16919, "Space data and information transfer systems - Requirements for bodies providing audit and certification of candidate trustworthy digital repositories". Six test audits were conducted of scientific data centers and archives in Europe and the United States to test the use of these draft standards and identify potential improvements for the standards and for the participating digital repositories. We present a case study of the test audit conducted on the NASA Socioeconomic Data and Applications Center (SEDAC) and describe the preparation, the audit process, recommendations received, and next steps to obtain certification as a trustworthy digital repository, after approval of the ISO/DIS standards.

  16. Monte Carlo implementation of a guiding-center Fokker-Planck kinetic equation

    A Monte Carlo method for the collisional guiding-center Fokker-Planck kinetic equation is derived in the five-dimensional guiding-center phase space, where the effects of magnetic drifts due to the background magnetic field nonuniformity are included. It is shown that, in the limit of a homogeneous magnetic field, our guiding-center Monte Carlo collision operator reduces to the guiding-center Monte Carlo Coulomb operator previously derived by Xu and Rosenbluth [Phys. Fluids B 3, 627 (1991)]. Applications of the present work will focus on the collisional transport of energetic ions in complex nonuniform magnetized plasmas in the large mean-free-path (collisionless) limit, where magnetic drifts must be retained

  3. A New Center for Science Education at UC Berkeley's Space Sciences Laboratory

    Hawkins, I.

    1998-01-01

    The Space Sciences Laboratory at UC Berkeley has established a new Center for Science Education through the Laboratory's Senior Fellow program. The Center has a two-fold mission: (1) science education research through collaborations with UCB Graduate School of Education faculty, and (2) education and outreach projects that bring NASA research to the K-14 and general public communities. The Center is the host of two major education and outreach programs funded by NASA - The Sun-Earth Connection Education Forum (SECEF) and the Science Education Gateway (SEGway) Project. The SECEF - a collaborative between UC Berkeley and NASA's Goddard Space Flight Center - is one of four Forums that have been funded through the Office of Space Science as part of their Education Ecosystem. SEGway is a partnership between science research centers, science museums, and teachers, for the purpose of developing Internet-based, inquiry activities for the K-12 classroom that tap NASA remote sensing data. We will describe the Center for Science Education's history and vision, as well as summarize our core programs.

  4. A Survey of a Remote Diagnosis Center for Nuclear Power Plants

    Methodologies for remote diagnosis have been developed and applied to medical care and lots of industrial fields. Modern science technologies such as a fast network, high computing power, sensing technology and advanced robot engineering make it possible to diagnose remote targets. Nuclear power plant(NPP) has highly connected network enabling systems. The systems (accumulated data analysis systems, alarm systems, main control panel, NPP database systems and so on) are connected with each other through a network. But remote diagnosis researches for a NPP have been developed individually. Efficient monitoring power, convenient management and a costcutting of the diagnosis will be provided through integration of the remote diagnosis technologies. The result of the integration can be represented as a remote diagnosis center. We propose an architecture of the remote diagnosis center for a NPP in this paper

  11. A Cell-Centered Multiphase ALE Scheme With Structural Coupling

    Dunn, Timothy Alan [Univ. of California, Davis, CA (United States)

    2012-04-16

    A novel computational scheme has been developed for simulating compressible multiphase flows interacting with solid structures. The multiphase fluid is computed using a Godunov-type finite-volume method. This has been extended to allow computations on moving meshes using a direct arbitrary-Eulerian- Lagrangian (ALE) scheme. The method has been implemented within a Lagrangian hydrocode, which allows modeling the interaction with Lagrangian structural regions. Although the above scheme is general enough for use on many applications, the ultimate goal of the research is the simulation of heterogeneous energetic material, such as explosives or propellants. The method is powerful enough for application to all stages of the problem, including the initial burning of the material, the propagation of blast waves, and interaction with surrounding structures. The method has been tested on a number of canonical multiphase tests as well as fluid-structure interaction problems.

    Walji, Muhammad; Loeffelholz, John; Valenza, John A

    2007-01-01

    Patients are often provided with sub-optimal information regarding their clinic visits. Patients sometimes forget post-discharge instructions provided verbally, and infrequently follow preventative advice to improve health. In this research we propose to develop and evaluate a dental discharge summary (DDS) for patients through a human-centered design process. Our long term goals are to automatically generate a personalized discharge summary after each clinic encounter to educate and motivate patients to maintain excellent oral health. PMID:18694242

  16. A cell-centered ICE method for multiphase flow simulations

    Kashiwa, B.A.; Padial, N.T. [Los Alamos National Lab., NM (United States); Rauenzahn, R.M. [Molten Metals Technology, Inc., Waltham, MA (United States); VanderHeyden, W.B. [Amoco Oil Co., Naperville, IL (United States)

    1993-12-01

    The Implicit Continuous-fluid Eulerian (ICE) method is a finite-volume scheme that is stable for any value of the Courant number based on the sound speed. In the incompressible limit, the ICE method becomes essentially identical to the Marker and Cell (MAC) method, so the two schemes are closely related. In this article, the classical ICE method is extended to multiple interpenetrating phases, and employed with a single control volume (nonstaggered) mesh framework. The incompressible limit is preserved, so that problems involving equations of state, or those exhibiting constant material densities, can be addressed with the same computer code. The scheme reduces properly to a single-fluid method, enabling benchmarking using well-known test cases. Thus, the numerical issues focus only on those aspects unique to problems having multiple density, velocity and temperature fields. The discussion begins with a derivation of the exact, ensemble-averaged equations. Examples of the most basic closures axe given, and the well-posedness of the equations is demonstrated. The numerical method is described in operator notation, and the discretization is sketched. The flow patterns in a bubble column are computed as an incompressible flow example. For a compressible flow example, the expansion and compression of a bubble formed by high-explosive gases under water is shown. In each case, comparison to experimental data is made.

  17. A construct-driven investigation of gender differences in a leadership-role assessment center.

    Anderson, Neil; Lievens, Filip; van Dam, Karen; Born, Marise

    2006-05-01

    This study examined gender differences in a large-scale assessment center for officer entry in the British Army. Subgroup differences were investigated for a sample of 1,857 candidates: 1,594 men and 263 women. A construct-driven approach was chosen (a) by examining gender differences at the construct level, (b) by formulating a priori hypotheses about which constructs would be susceptible to gender effects, and (c) by using both effect size statistics and latent mean analyses to investigate gender differences in assessment center ratings. Results showed that female candidates were rated notably higher on constructs reflecting an interpersonally oriented leadership style (i.e., oral communication and interaction) and on drive and determination. These results are discussed in light of role congruity theory and of the advantages of using latent mean analyses. PMID:16737354

  18. Karyotype Learning Center: A Software For Teaching And Learning Cytogenetics

    Joelma Freire De Mesquita

    2004-05-01

    Full Text Available The in vitro cultivation of human cells is an essential part of the work of every diagnostic cytoge-netics laboratory. Almost all human cytogenetic studies involve the examination of dividing bloodcell population by blocking cell division at metaphase with subsequent processing and staining bybanding techniques. The chromosome constitution is described as Karyotype that states the totalnumber of chromosomes and the sex chromosome constitution. Karyotypes are prepared by cuttingup a photograph of the spread metaphase chromosomes, matching up homologous chromosomes andsticking them back down on a card or nowadays more often by getting an image analysis computerto do the job. Chromosomes are identied by their size, centromere position and banding pattern.Teaching a student how to detect and interpret even the most common chromosome abnormaliti-es is a major challenge: mainly, in a developing country where the laboratorial facilities are notalways available for a big number of students. Therefore, in this work we present an educationalsoftware for teaching undergraduate students of Medical and Life Sciences Courses how to arrangenormal and abnormal chromosomes in the form of karyotype. The user, using drag-and-drop, is da-red to match up homologous chromosome. For that, we have developed a free full access web site(http://www.biomol.net/cariotipo/ for hosting the software. The latter has proved to be light andfast even under slow dial-up connections. This web site also oers a theoretical introductory sectionwith basic concepts about karyotype. Up to now the software has been successfully applied to un-dergraduate courses at the University of Rio de Janeiro (UNIRIO. The students have approved thesoftware; to them the similarities with the well-known game solitaire turns the exercise more excitingand provides additional stimulus to learn and understand karyotype. Professors have also used thesoftware as complementary material in their regular classes

    Wilson, Chauncey

    2013-01-01

    Brainstorming and Beyond describes the techniques for generating ideas verbally, in writing, or through sketches. The first chapter focuses on brainstorming, the foundation method for ideation, which is a complex social process building off of social psychology principles, motivational constructs, and corporate culture. Brainstorming is commonly portrayed as an easy way to generate ideas, but in reality, it is a complex social process that is often flawed in ways that are not self-evident. Chapter 2 discusses Brainwriting, which is a variation on brainstorming in which each person writes idea

    van den Broek, Annika; Williams, Vaughan K; Revesz, Tamas; Suppiah, Ram

    2015-05-01

    Recent literature has reported an apparent increase in the incidence of pediatric venous thromboembolism over the last 10 years. In our study, data were collected from all children (ages 0 to 18 y) with a thrombotic event between January 2000 and May 2012, to determine whether an increased incidence of thromboembolism (TE) was evident and to investigate mitigating factors in the development of the TE. A total of 134 patients were entered into the study, 42% under the age of 1 year. There was no conclusive evidence of an increased incidence in our population over the period of the study. Within our population the peripheral venous system was the most common location for TE followed by cerebral vascular accidents. A thrombophilic risk factor was found in 84% of the patients. In our study 4.5% of the children had a second event. PMID:25887641

  2. Towards a realistic astrophysical interpretation of the Galactic center excess

    Gaggero, Daniele; Urbano, Alfredo; Valli, Mauro; Ullio, Piero

    2015-01-01

    A spherical-symmetric gamma-ray emission from the central region of the Galaxy has been recently identified in Fermi-LAT data, and initially associated to dark matter particle annihilations. Guided by the evidence for a high gas density in the inner kpc of the Galaxy correlated with a very large Supernova rate, and hence with ongoing cosmic-ray acceleration, we investigate instead the possibility of addressing this excess in terms of ordinary cosmic-ray sources and standard steady-state diffusion. We introduce the new ingredient in the context of the template-fitting algorithm, treating the new contribution as correlated to the conventional Inverse Compton emission. We analyze in detail the overall goodness of the fit of our framework, and perform a detailed direct comparison against data examining profiles in different directions.

    dos Santos, Marcelo; Fujino, Asa

    2011-03-01

    Learning radiology requires systematic and comprehensive study of a large knowledge base of medical images. In this work is presented the development of a digital radiology teaching file system. The proposed system has been created in order to offer a set of customized services regarding to users' contexts and their informational needs. This has been done by means of an electronic infrastructure that provides easy and integrated access to all relevant patient data at the time of image interpretation, so that radiologists and researchers can examine all available data to reach well-informed conclusions, while protecting patient data privacy and security. The system is presented such as an environment which implements a distributed clinical database, including medical images, authoring tools, repository for multimedia documents, and also a peer-reviewed model which assures dataset quality. The current implementation has shown that creating clinical data repositories on networked computer environments points to be a good solution in terms of providing means to review information management practices in electronic environments and to create customized and contextbased tools for users connected to the system throughout electronic interfaces.

    It is very common to have a class of 50 or more students in Chinese schools,and teaching a foreign language effectively to a large class is really hard work.In order to change the teacher-centered teaching model into the student-centered one,Teachers should keep students' needs,interests,and learning styles in mind,apply several kinds of teaching techniques,organize different clas$1~OIlll activities and encourage,praise and appreciate both students' success and learning process all the time.If teachers place more responsibility in the hands of students,serve as "presenter or facilitator of knowledge"instead of "source of all knowledge",they can greatly motivate students to learn the language in a very active,cooperative andeffectiveway.After all,peoplelearn by doing,not only by watching andlistening.

  10. Concepts and strategies to establish a cyclotron/PET center

    Cyclotron accelerators are prolific sources of charged particle for the production of radionuclides and have become an essential tool in the practice of modern nuclear medicine by providing reliably radiotracers for SPECT and PET studies. In a recent survey conducted by the IAEA in 2001 (1) , the growth in the number of cyclotron facilities installed in laboratories and hospitals in developed as well as developing nations was put into evidence This trend, which started in the late 70's, continues up to the present time, and all indications are that it will continue in the next future. The reasons for this growth are several, amongst them it can be mentioned the fact that the technology involved has became more user or 'hospital friendly', third party reimbursement for several of clinical studies based on F-18 PET radiopharmaceuticals at least in some of the advanced countries starting with F-18FDG in 1998, and above all, the clear, irrefutable and demonstrable Conclusion of the positive cost/benefit outcomes of PET studies in the field of oncology and to a lesser degree, thus far, for cardiology and neurology. It is however recognized that the overall financial cost of the technology, which comprises the premises to house the facility, the cyclotron accelerator, the corresponding radiochemistry and quality control equipment and the PET camera can nevertheless be an expensive proposition that requires careful advance planning. This fact is even more relevant when the facility is planed for installation in a developing country which frequently, in addition to having a lack of sufficient financial resources, do have shortages of qualify human resources for advance planning and later, to run efficiently the facility. Several are the steps that needs consideration when planning a cyclotron facility, the most critical ones are a careful definition of the mission and scope of the facility including the utilization programme of the facility as a whole, followed by a

  11. Performance Analysis of Heterogeneous Data Centers in Cloud Computing Using a Complex Queuing Model

    Wei-Hua Bai

    2015-01-01

    Full Text Available Performance evaluation of modern cloud data centers has attracted considerable research attention among both cloud providers and cloud customers. In this paper, we investigate the heterogeneity of modern data centers and the service process used in these heterogeneous data centers. Using queuing theory, we construct a complex queuing model composed of two concatenated queuing systems and present this as an analytical model for evaluating the performance of heterogeneous data centers. Based on this complex queuing model, we analyze the mean response time, the mean waiting time, and other important performance indicators. We also conduct simulation experiments to confirm the validity of the complex queuing model. We further conduct numerical experiments to demonstrate that the traffic intensity (or utilization of each execution server, as well as the configuration of server clusters, in a heterogeneous data center will impact the performance of the system. Our results indicate that our analytical model is effective in accurately estimating the performance of the heterogeneous data center.

    2009-01-01

    Full Text Available Background: The chronic use of immunosuppressants in renal transplant recipients (RTRs predisposes them to a variety of skin manifestations. Studies on skin lesions in RTRs from India have been limited. Aim: To study the prevalence and clinical spectrum of skin diseases in RTR in patients attending the Nephrology clinic of a tertiary care hospital in South India. Methods: Between October 2002 and June 2003, 365 RTRs were evaluated for skin lesions, including 280 examined after renal transplant (group A and 85 examined once before and then monthly after transplant for a period of 6 months (group B. Results: A total of 1163 skin lesions were examined in 346 RTRs (94.7% including lesions of aesthetic interest (LAI [62.3%] followed by infections [27.3%]. All LAI were drug-related manifestations, making it the most common skin lesion, while fungal (58.7% and viral (29.3% infections constituted majority of lesions caused by infection. Lesions related to neoplasms were relatively uncommon (2.1% and all lesions were benign. Miscellaneous lesions constituted 8.3% of skin lesions, which included vaccine-induced necrobiotic granulomas at the site of Hepatitis B vaccination and acquired perforating dermatoses. Conclusion: Skin lesions among RTRs from India consist predominantly of drug-related LAI and infections and are different from the West in view of the paucity of neoplastic lesions.

  14. An organizing center in a planar model of neuronal excitability

    Franci, Alessio; Sepulchre, Rodolphe

    2012-01-01

    The paper studies the excitability properties of a generalized FitzHugh-Nagumo model. The model differs from the purely competitive FitzHugh-Nagumo model in that it accounts for the effect of cooperative gating variables such as activation of calcium currents. Excitability is explored by unfolding a pitchfork bifurcation that is shown to organize five different types of excitability. In addition to the three classical types of neuronal excitability, two novel types are described and distinctly associated to the presence of cooperative variables.

    Capsule endoscopy (CE) is a novel technology that facilitates highly effective and noninvasive imaging of the small bowel. Although its efficacy in the evaluation of obscure gastrointestinal bleeding (OGIB) has been proven in several trials, data on uses of CE in different small bowel diseases are rapidly accumulating in the literature, and it has been found to be superior to alternative diagnostic tools in a range of such diseases.Based on literature evidence, CE is recommended as a first-line investigation for OGIB after negative bidirectional endoscopy. CE has gained an important role in the diagnosis and follow-up of Crohn's disease and celiac disease and in the surveillance of small bowel tumors and polyps in selected patients. Capsule retention is the major complication, with a frequency of 1%-2%. The purpose of this review was to discuss the procedure, indications, contraindications and adverse effects associated with CE. We also review and share our five-year experience with CE in various small bowel diseases. The recently developed balloon-assisted enteroscopies have both diagnostic and therapeutic capability. At the present time, CE and balloon-assisted enteroscopies are complementary techniques in the diagnosis and management of small bowel diseases.
