    Air monitors that operate continuously are used in nuclear facilities to detect unexpected malfunctions in controls that limit levels of airborne radioactivity in occupied area. Monitoring for concentrations of alpha-emitting transuranics is the most difficult task in air monitoring. Workplace monitoring for alpha emitters requires a detection level ∼2% that of nonalpha-emitting radionuclides with a half-life >2 h. Typically, air monitoring is accomplished by passing a volume of the monitored air through a filter to collect the particulates. The filter is located near a detector that monitors the radioactivity of the collected particles and sends an alarm when the activity exceeds established limits. Alpha activity from daughters of thoron and radon, present in all air in variable amounts, hampers monitoring for transuranics. This presentation describes developments that have improved the accuracy and sensitivity for the monitoring of airborne concentration of transuranics

    A case-based approach was used in a two-day periodontal continuing professional development course as a strategy to stimulate active learning. The present study investigates the outcome of this course format in terms of feasibility, perceived efficiency as a learning approach and reported individual learning goals. The study was performed in five identical courses entitled'risk analysis and treatment in periodontal patients'at Malmö University between 2011-2014. Before the course, clinical cases were used to activate participants' prior knowledge and to attune their focus on the course content. During the course, cases were discussed to synchronise theory with practical application. A pre- and end-course questionnaire were developed to evaluate participants' characteristics (age, clinical expertise, experience and expectations), perceptions on feasibility and instructiveness and emerged individual learning goals. The participants (39 dentists and 78 dental hygienists) reported an average preparation time of 62 minutes (range 2-190) and had positive perceptions on the accessibility, instructiveness and difficulty of cases. Expectations ranged between refreshing, acquiring new knowledge and mastering the course subject. Most reported learning goals were related to daily clinical practice including the development of a treatment plan, when to continue non-surgical treatment or to extract teeth/perform surgery, the approach to periodontitis, how to motivate non-compliant patients and when to refer. Conclusion: The use of clinical cases to stimulate active learning in a short-term continuing professional development periodontal course was positively perceived by the dentists and dental hygienists in terms of feasibility and learning potential.

    evolution does not make the platforms irrelevant. This research is based on case studies and applications in the two Danish companies, LEGO and Grundfos, where several platform development projects have been followed. LEGO is exceptional for their long experience with platform development and maintenance......, while Grundfos is relatively new within this area. This study puts emphasis on platform projects and defines such projects as something very different from product development projects and more similar to industrial research projects, due to the fact that they are continuous activities with relatively...... low risks and investments but also with relatively fuzzy results. When looking for new platform projects, it is important to make sure that the company and market is ready for the introduction of platforms, and to make sure that people from marketing and sales, product development, and downstream...

    Development activities related to the Rapid Cycle Amine (RCA) Carbon Dioxide (CO2) and Humidity control system have progressed to the point of integrating the RCA into an advanced Primary Life Support System (PLSS 2.0) to evaluate the interaction of the RCA among other PLSS components in a ground test environment. The RCA 2.0 assembly (integrated into PLSS 2.0) consists of a valve assembly with commercial actuator motor, a sorbent canister, and a field-programmable gate array (FPGA)-based process node controller. Continued design and development activities for RCA 3.0 have been aimed at optimizing the canister size and incorporating greater fidelity in the valve actuator motor and valve position feedback design. Further, the RCA process node controller is envisioned to incorporate a higher degree of functionality to support a distributed PLSS control architecture. This paper will describe the progression of technology readiness levels of RCA 1.0, 2.0 and 3.0 along with a review of the design and manufacturing successes and challenges for 2.0 and 3.0 units. The anticipated interfaces and interactions with the PLSS 2.0/2.5/3.0 assemblies will also be discussed.

    2009-12-01

    Continuous active-source monitoring using borehole sources and sensors in a crosswell configuration has proven to be a useful tool for monitoring subsurface processes (Silver, et al, 2007; Daley, et al, 2007; Niu, et al, 2008). This recent work has focused on two applications: monitoring stress changes related to seismicity and monitoring changes in fluid distribution related to geologic storage of CO2. Field tests have demonstrated precision in travel time measurement of up to 1.1 x 10-7 s, and in velocity perturbation measurement of up to 1.1 x 10-5 (Niu, et al 2008). In this talk I will summarize our preceding work and discuss current developments. Current efforts address both hardware and design challenges to improving the methodology. Hardware issues include deployment of multiple piezoelectric sources in shallow and deep boreholes, source and sensor deployment on tubing inside casing, and deployment with other monitoring instrumentation. Design issues are focused on use of multiple sources and/or sensors to obtain optimal spatial resolution for monitoring processes in the interwell region. This design issue can be investigated with optimal experiment design theory. New field experiments for monitoring seismicity (at SAFOD) and CO2 injection (at a US Dept of Energy pilot) are in the design/deployment stage. Current status of these projects will be discussed.

    To effectively enhance professional development, it is important to understand the motivational factors behind nurses' engagement in particular types of learning activities. Nurses have various motives for professional development and utilise different learning activities. Not much is known about how these relate. The aim of this study was to explore the relationship between nurses' motives and activities for continuing professional development, by examining in which types of learning activities nurses engage, with which motives, and whether certain motives are associated with certain learning activities. A qualitative study using semi-structured interviews. Twenty-one nurses in academic and general Dutch hospitals participated. Interview data on nurses' learning biographies were analysed using a literature-based framework on motives and learning activities for continuing professional development. As recent classifications of nurses' motives for professional development were absent, the literature was reviewed for motives, using three databases. The interview transcripts were analysed for motives, learning activities and their relationships. Nine motives and four categories of learning activities for continuing professional development were delineated. Increasing competence was the primary motive that stimulated nurses to engage in self-directed learning during work, and in formal learning activities. To comply with requirements, they engaged in mandatory courses. To deepen knowledge, they registered for conferences. To develop their careers, they enrolled in postgraduate education. Five other motives were not mentioned as frequently. Specific motives were found to be related to engagement in particular learning activities. Nurses could use these findings to increase their awareness of why and how they develop professionally, and managers and human resource development professionals could develop approaches that would better suit nurses' needs.

    2013-08-01

    Full Text Available Maintenance of professional competence remains an exercise of permament learning and an essential requirement for evidence –based medical practice. Physicians attend continuing professional development (CPD programs to acquire new knowledge. Often CPD programs remain the main source for updates of information. CPD organizers have a considerable responsibility in determining appropriate curriculum for their conferences. Organizing an effective CPD activity often requires understanding of the principles of adult education. Prior to deciding on the curriculum for a CPD, course organizers should conduct needs assessment of physicians. CPD planners should create activities that would consistently improve physician competence. CPD sessions that are interactive, using multiple methods of instructions for small groups of physicians from a single specialty are more likely to change physician knowledge and behavior. The effectiveness of a CPD program should be evaluated at a level beyond measuring physician satisfaction. CPD planners should incorporate methods to determine the course attendees’ improvement of knowledge, skills and attitudes during the CPD activities. Pre and post conference evaluations of physicians using multiple choice questions may form a useful method of assessment.

    Over the last few years great progress has been made in the technological development of Monolithic Active Pixel Sensors (MAPS) such that upgrades to existing vertex detectors using this technology are now actively being considered. Future vertex detection at an upgraded KEK-B factory, already the highest luminosity collider in the world, will require a detector technology capable of withstanding the increased track densities and larger radiation exposures. Near the beam pipe the current silicon strip detectors have projected occupancies in excess of 100%. Deep sub-micron MAPS look very promising to address this problem. In the context of an upgrade to the Belle vertex detector, the major obstacles to realizing such a device have been concerns about radiation hardness and readout speed. Two prototypes implemented in the TSMC 0.35 μm process have been developed to address these issues. Denoted the Continuous Acquisition Pixel, or CAP, the two variants of this architecture are distinguished in that CAP2 includes an 8-deep sampling pipeline within each 22.5 μm 2 pixel. Preliminary test results and remaining R and D issues are presented

    The success of a profession will be determined upon its education and training. A profession is required to encompass: a core body of knowledge; a set of ethical codes of practice; and have practitioners with humanistic qualities. In order to maintain the success of a profession it is necessary to have continuing education, which enhances professional development. Continuing professional education includes a form of self-regulation, which ensures the maintenance of a minimum standard of practice in this ever-changing workplace, and by regulating this standard, the discipline becomes more accountable to the client and the profession as a whole. In Australia, the Nuclear Medicine society's continuing education programs and Universities offering postgraduate programs promote continuing education. If technologists are to successfully keep up with developments in instrumentation, protocols and changing health care requirements, we must ensure that the education of practitioners does not cease at certification of entry to the workplace (Au)

    Continuing professional development (CPD) is one of the principal means by which health professionals (i.e. primary care physicians and specialists) maintain, improve, and broaden the knowledge and skills required for optimal patient care and safety. However, the lack of a widely accepted instrument to assess the impact of CPD activities on clinical practice thwarts researchers' comparisons of the effectiveness of CPD activities. Using an integrated model for the study of healthcare professionals' behaviour, our objective is to develop a theory-based, valid, reliable global instrument to assess the impact of accredited CPD activities on clinical practice. Phase 1: We will analyze the instruments identified in a systematic review of factors influencing health professionals' behaviours using criteria that reflect the literature on measurement development and CPD decision makers' priorities. The outcome of this phase will be an inventory of instruments based on social cognitive theories. Phase 2: Working from this inventory, the most relevant instruments and their related items for assessing the concepts listed in the integrated model will be selected. Through an e-Delphi process, we will verify whether these instruments are acceptable, what aspects need revision, and whether important items are missing and should be added. The outcome of this phase will be a new global instrument integrating the most relevant tools to fit our integrated model of healthcare professionals' behaviour. Phase 3: Two data collections are planned: (1) a test-retest of the new instrument, including item analysis, to assess its reliability and (2) a study using the instrument before and after CPD activities with a randomly selected control group to explore the instrument's mere-measurement effect. Phase 4: We will conduct individual interviews and focus groups with key stakeholders to identify anticipated barriers and enablers for implementing the new instrument in CPD practice. Phase 5

    With the stellarator W7-X a step to quasi-continuous plasma operation will be made. The cooling system of the machine is designed such that two 30 min discharges can be run per day. Right from the start of operation 10 MW of ECRH heating power will be available for quasi-continuous operation. A working group 'Plasma Facing Optical Components' has been formed which presently concentrates on the development of water cooled windows for UV/VR/IR periscopes which can withstand the expected maximum heat loads of up to 50 kW/m 2 which due to the predominantly short wavelength nature of the radiation emitted by the plasma will be absorbed within the first millimeter of any window. We will report on the detailed Finite Element (ANSYS R ) calculations of the heat and stress distribution across the windows. Calculations have been undertaken for a large number of different window materials which are required for the various spectral regions covered by the miscellaneous diagnostics, so that the most suitable material for each application can easily be identified. Also the dependence of the cooling rate on the window diameter and thickness has been studied. The calculations show that at a power load of 50 kW/m 2 cooled sapphire windows can be used for window sizes up to ∼200 mm diameter but that for many of the other materials like ZnSe, ZnS, CaF 2 , MgF 2 and quartz window sizes need to be limited to considerably smaller sizes. Detailed simulations of the local radiation power load distribution demonstrate that by careful design the load on individual optical components can be considerably reduced. A vacuum test chamber, equipped with a vacuum compatible IR heater has been build. In this chamber a low cost, easily exchangeable window design using Helicoflex gaskets on either side of a 60 mm exposed diameter quartz window have been successfully tested over 70 heat cycles up to a maximum temperature of 450 o C at power loads of 15 kW/m 2 .

  4. Sleep behaviour: sleep in continuously active dolphins.

    2006-06-22

    Sleep has been assumed to be necessary for development and to be a vital function in mammals and other animals. However, Lyamin et al. claim that in bottlenose dolphins (Tursiops truncatus) and killer whales (Orcinus orca), neonates and their mothers show almost no sleep behaviour for the first month after birth; this conclusion is based on their observation that the cetaceans keep swimming, avoid obstacles and rarely close their eyes for 24 hours a day throughout that period. Here we analyse the behaviour and eye closure of three neonate-mother pairs of bottlenose dolphins and find that, although the animals tend to open both eyes when surfacing to breathe, one or both eyes are closed during 'swim rest', an underwater sleeping behaviour that is associated with continuous activity. This observation calls into question the conclusions of Lyamin et al., who overlooked this type of sleep by analysing the animals' eye state only when they surfaced to breathe.

Methods and Materials: Ambulatory patients who were planned for treatment with concurrent chemoradiotherapy with curative intent for cancers of the head and neck, lung, or gastrointestinal tract were provided with activity monitors before treatment initiation. Patients were asked to wear the devices continuously throughout the radiation therapy course. Step count data were downloaded weekly during radiation therapy and 2 and 4 weeks after radiation therapy completion. The primary objective was to demonstrate feasibility, defined as collection of step counts for 80% of the days during study subjects' radiation therapy courses. Secondary objectives included establishing step count as a dynamic predictor of unplanned hospitalization risk. Results: Thirty-eight enrolled patients were treated with concurrent chemoradiotherapy. Primary diagnoses included head and neck cancer (n=11), lung cancer (n=13), and a variety of gastrointestinal cancers (n=14). Step data were collected for 1524 of 1613 days (94%) during patients' radiation therapy courses. Fourteen patients were hospitalized during radiation therapy or within 4 weeks of radiation therapy completion. Cox regression modeling demonstrated a significant association between recent step counts (3-day average) and hospitalization risk, with a 38% reduction in the risk of hospitalization for every 1000 steps taken each day (hazard ratio 0.62, 95% confidence interval 0.46-0.83, P=.002). Inferior quality of life scores and impaired performance status were not associated with increased hospitalization risk. Conclusion: Continuous activity monitoring during concurrent chemoradiotherapy is feasible and well-tolerated. Step counts may serve as powerful, objective, and dynamic indicators of hospitalization risk.

    Full Text Available Despite increased attention to internal controls and risk assessment, traditional audit approaches do not seem to be highly effective in uncovering the majority of frauds. Less than 20 percent of all occupational frauds are uncovered by auditors. Forensic accounting has recognized the need for automated approaches to fraud analysis yet research has not examined the benefits of forensic continuous auditing as a method to detect and deter corporate fraud. The purpose of this paper is to show how such an approach is possible. A model is presented that supports the acceptance of forensic continuous auditing by auditors and management as an effective tool to support the audit function, meet management’s regulatory objectives, and to combat fraud. An approach to developing such a system is presented.

    Competence is traditionally viewed as the attainment of a static set of attributes rather than a dynamic process in which physicians continuously use their practice experiences to "progress in competence" toward the attainment of expertise. A competency-based continuing professional development (CPD) model is premised on a set of learning competencies that include the ability to (a) use practice information to identify learning priorities and to develop and monitor CPD plans; (b) access information sources for innovations in development and new evidence that may potentially be integrated into practice; (c) establish a personal knowledge management system to store and retrieve evidence and to select and manage learning projects; (d) construct questions, search for evidence, and record and track conclusions for practice; and (e) use tools and processes to measure competence and performance and develop action plans to enhance practice. Competency-based CPD emphasizes self-directed learning processes and promotes the role of assessment as a professional expectation and obligation. Various approaches to defining general competencies for practice require the creation of specific performance metrics to be meaningful and relevant to the lifelong learning strategies of physicians. This paper describes the assumptions, advantages, and challenges of establishing a CPD system focused on competencies that improve physician performance and the quality and safety of patient care. Implications for competency-based CPD are discussed from an individual and organizational perspective, and a model to bridge the transition from residency to practice is explored.

    2008-07-26

    Ever-increasing needs and demands by dentists and all other members of the dental team for education and training at all levels - undergraduate, postgraduate and continuing - are straining the resources of existing providers of such education. At the same time, there are ever-increasing opportunities to develop online delivery and the use of a range of information and communication technology (ICT) systems and services further, in all aspects of dental education. This paper reviews recent developments that have led to an increased demand for dental postgraduate programmes and continuing professional development (CPD) courses in the United Kingdom and then discusses how ICT has and will impact on teaching practice. Examples include the use of teaching and learning resources in a virtual learning environment (VLE) and the increasing use of blended learning. The paper then explores the need for both teachers and students to adapt to the new environment to ensure they can benefit to the maximum and that teaching and learning practices are changed accordingly.

    Competency based medical education (CBME) has become the default for undergraduate and post-graduate medical education (PGME) but its role in continuing professional development (CPD) is under discussion. Some critical differences between CPD and PGME are identified and these differences applied to: the relative roles of competence and performance; existing criticisms of CBME; heutagogy as a learning theory; and post-modernism as an underlying philosophical perspective. The argument is made that the characteristics of CPD fit with performance based medical education, a heutagogical learning theory, a focus on capabilities, rather than competencies; and a post-modern perspective.

  5. Local anesthetic systemic toxicity: Continuing Professional Development.

    Science.gov (United States)

    El-Boghdadly, Kariem; Chin, Ki Jinn

    2016-03-01

    Regional anesthesia is enjoying a renaissance due in part to the advent of ultrasound guidance and the development of new techniques such as tissue plane blocks and local infiltration analgesia. The purpose of this Continuing Professional Development module is to provide practitioners with an understanding of the current state of knowledge surrounding local anesthetic systemic toxicity (LAST) in order to help them prevent and manage this complication more effectively. The causes of LAST are multifactorial, but recognized risks include patient factors, drug doses, pharmacokinetics, and choice of regional anesthetic technique. Local anesthetic systemic toxicity produces a biphasic course of clinical events that generally begin with central nervous system excitation followed by inhibition. At the same time, it causes cardiovascular compromise due to dysrhythmias, myocardial depression, and reduced systemic vascular resistance. Clinical presentation can be highly variable, however, and atypical presentations are not uncommon. Local anesthetic systemic toxicity is prevented by careful choice and dosing of drugs, aspiration before injection, dose fractionation, use of intravascular markers and ultrasound guidance. The management of LAST includes adequate oxygenation and ventilation, seizure termination, maintenance of circulation, and intravenous lipid emulsion therapy. Local anesthetic systemic toxicity is a potentially lethal condition with protean manifestations, and anesthesiologists must understand its risks, prevention, and safe management.

    2014-01-01

    The increasing availability of animal tracking data brings us opportunities and challenges to intuitively understand the mechanisms of animal activities. In this paper, we aim to discover animal movement patterns from animal trajectory data. In particular, we propose a notion of continuous activity pattern as the concise representation of underlying similar spatio-temporal movements, and develop an extension and refinement framework to discover the patterns. We first preprocess the trajectories into significant semantic locations with time property. Then, we apply a projection-based approach to generate candidate patterns and refine them to generate true patterns. A sequence graph structure and a simple and effective processing strategy is further developed to reduce the computational overhead. The proposed approaches are extensively validated on both real GPS datasets and large synthetic datasets.

    Full Text Available Professional development is considered as an essential element in enhancing the teaching and learning process to ensure student learning. Professional development can also be deemed as a cornerstone of teacher professionalism and quality. The governments and educational institutions invest significantly in Continuous Professional Development (CPD to improve teacher quality and to meet the changing needs of the students. To uncover the perceptions and practices of professional development in Saudi Arabia, a survey was conducted at Taif University English Language Centre. The sample consisted of 121 English language teachers from various countries and having varied educational and academic experiences. The survey comprised items relevant to learning approaches, concept of professional development, perceptions and feedback on CPD. The respondents supported lifelong learning and experiential learning leading towards learner centered approach. They perceived the CPD as a challenge to their existing knowledge and classroom practice. However, they expressed their concerns regarding indigenization of activities in CPDs, institutional support in conducting classroom activities, and follow up activities.  Keywords: Professional development, Teacher perception, ELT in Saudi Arabia

    Peer review panels composed of 80 external scientists recently visited Oak Ridge National Laboratory (ORNL) to review almost 700 proposals for experiments on 23 instruments at the Spallation Neutron Source (SNS) and High Flux Isotope Reactor (HFIR). These were proposed for the time period from January-June 2012. About 40% of the proposals were approved for beam time and 20% were placed on an alternate list if time becomes available. The Hybrid Spectrometer HYSPEC at SNS began its commissioning in September 2011. HYSPEC is otpimized for studying low energy dynamics in single-crystal samples using a broad variety of sample environments, and is equipped with a polarization analysis capability. It is expected to be available for users on a limited basis in the second half of 2012. The detector tank of CORELLI has been installed on beamline 9 at SNS. Now that the tank is in place, banks of neutron detectors and boron carbide shielding will be installed around the interior. CORELLI is optimized to probe complex disorder in crystalline materials through diffuse scattering from single-crystal samples. It will begin commissioning in 2014. CORELLI is one of four instruments being developed under the SING II (SNS Instruments Next Generation II) project. The others are the Macromolecular Neutron Diffractometer (MANDI), the Vibrational Spectrometer (VISION, scheduled to begin commissioning in 2012), and the Time of Flight Ultra Small Angle Neutron Scattering Instrument (TOF-USANS).

    2017-05-01

    Midwifery education plays an important role in educating graduates about engaging in continuous professional development (CPD) but there is a lack of empirical research analysing student midwives' awareness of CPD beyond graduation. We aimed to explore student midwives' awareness of the need to become lifelong learners and to map their knowledge of CPD activities available after graduation. Therefore, forty-seven reflective documents, written in the last week of student midwives' training programme, were analysed in a thematic way. Content analysis confirmed student midwives' awareness of the importance of CPD before graduation. They mentioned different reasons for future involvement in CPD and described both, formal and informal CPD-activities. Respondents were especially aware of the importance of knowledge, to a lesser degree of skills-training and still less of the potential value of the Internet for individual and collective learning. Respondents perceived a need for a mandatory preceptorship. Supporting learning guides were highly valued and the importance of reflection on CPD was well-established. This could have resulted from an integrated reflective learning strategy during education. Undergraduate midwives are aware of the importance of CPD and the interplay of formal and informal learning activities. Virtual learning requires special attention to overcome CPD challenges.

    2014-01-01

    Most of Continuous air monitors used for the measurement of air borne activity at nuclear plants are bulky in size, makes lot of noise (> 70 DB) due to belt derive vacuum pump. In addition to that users also face difficulties in displacement of the instrument from one location to another location. To overcome these problems, a compact and portable continuous Beta air monitor was indigenously designed and developed which has extremely low noise level and has shown excellent performance for the measurement of air borne activity. The details of the design and development of portable continuous beta air monitor are presented in this paper. Compact design makes the instrument light in weight and easy to displace it from one location to another location. Shielding design of the detector and filter holder assembly is very effective to reduce the interference of external gamma. Replacement of filter papers in this design of filter holder is much easier and convenient than old model filter holders. The integrity of leak tightness of the system ensures collection efficiency more than 99 % for sub micron particles. Observed efficiency of the detector with 5 mm minimum air gap between filter paper and detector is 13% which is 1.5 times higher than earlier model. Use of motor mounted vacuum pump and silencer was found quite effective to reduce the noise level upto 70 DB. Introduction of electronic air flow sensor provides additional features to get flow rate at the time of individual alarm conditions. Self diagnostic features like detector fail, HV fail and pump fail indications on display system helps to identify the specific type of faults. Internal memory of display unit can store all such data with date and time in programmable intervals (0-250 minutes)

  1. The uptake of Continuing Professional Development (CPD) by Ghanaian radiographers

    International Nuclear Information System (INIS)

    Gawugah, James N.K.; Jadva-Patel, Hansa; Jackson, Marcus T.

    2011-01-01

    Continuing professional development (CPD) currently gains a priority within healthcare professions all over the globe. It is playing important roles in achieving improved quality care delivery. Healthcare practitioners are expected to continuously undertake CPD to maintain, enhance and improve quality of service delivery to meet the consumers' expectations. CPD offers practitioners the opportunity to retain and enhance the basic knowledge and skills through their working life; thus enhancing competency within one's professional range of practice. In Ghana, awareness of CPD participation has not been created among healthcare practitioners to enable them engage in effective CPD activities in order to improve their knowledge and skills. Purpose: To examine the level of radiographers' participation in CPD activities in Ghana. Method: A 21-item questionnaire was constructed to collect data from 80 participants drawn from among radiographers currently practising in the radiology/X-ray departments of the ten regional hospitals in Ghana. The questionnaire comprised of 3 sections: demographics, CPD and education specific sections. Out of 80 questionnaires administered, 42 were completed and returned representing 52.5%. Out of the percentage, 74% were males and 26% females. The findings highlight that majority (44%) of the participants are currently within the age group of 31-40 years, while 2% is/are 60 or more years. The article also reveals that the radiographers have access to few peer review journals which serve as sources of information on contemporary issues in radiography and CPD learning activities. Again, a generally poor level of CPD awareness among the Ghanaian radiographers has been established. Lack of effective recording of learning and CPD activities have also been revealed. Conclusion: The article concludes by recommending CPD policy guidelines; a regulatory body to register all healthcare professionals under one body to ensure effective CPD participation by

    Full text: The purpose is to present the activities of Department of Radiation technologists at Medical College Sofia in knowledge management (KM) in human health applications and namely: continuous development of academic curriculum (AC) for medical radiation technologists (MRT) in sense of the conference motto “Nuclear Knowledge Management: Challenges and Approaches”. Our challenge is to realize, in practice, the important role of MRT professionals in healthcare. They are the front line in the patient safety and the last person with the patient before exposure. The existing AC has been periodically peer-reviewed: in 2011, 2014, and ongoing reviews, with the aim to guarantee that we are providing knowledge, skills and competencies that meet modern requirements for the training of radiation technologists. The AC compromises both academic and clinical education. The clinical component occurs throughout the academic course, accenting the role of MRT in radiology, radiotherapy and nuclear medicine. The approach of continuously developing the AC will meet the stringent requirements recently published by IAEA, with the goal that radiological medical practitioners, medical physicists, medical radiation technologists and other health professionals with specific duties in relation to protection and safety for patients in a given radiological procedure are specialized in the appropriate area.

    Training for dental practitioners in implant dentistry ranges from 1- or 2-day short Continuing Professional Development (CPD) courses to certificate/diploma programmes run by universities. In general, the teaching of implant dentistry in Europe lacks structure and standardisation. This paper aims to: (i) identify the current trends in CPD in implant dentistry in Europe; (ii) identify potential and limitations with regards to the design and implementation of CPD activities in implant dentistry; (iii) provide recommendations on the future structure and development of CPD activities in implant dentistry. A search of the literature was undertaken in PubMed for manuscripts published in English after 2000 reporting on CPD in dentistry and in implant dentistry in particular. In addition, an electronic survey was conducted, investigating the attitudes towards CPD among a wide group of stakeholders in implant dentistry education. There is a wide diversity of educational pathways towards achieving competences in implant dentistry through CPD. At present, there is a need for improving the CPD structures in implant dentistry, strengthening the quality assurance and encouraging standardisation and transparency of the learning outcomes. Development of a structured CPD system with clearly defined educational objectives mapped against specific levels of competence is recommended. © 2014 John Wiley & Sons A/S.

    To develop and pilot test a generic questionnaire to measure continuity of care from the patient's perspective across primary and secondary care settings. We developed the Nijmegen Continuity Questionnaire (NCQ) based on a systematic literature review and analysis of 30 patient interviews. The questionnaire consisted of 16 items about the patient-provider relationship to be answered for five different care providers and 14 items each on the collaboration between four groups of care providers. The questionnaire was distributed among patients with a chronic disease recruited from general practice. We used principal component analysis (PCA) to identify subscales. We refined the factors by excluding several items, for example, items with a high missing rate. In total, 288 patients filled out the questionnaire (response rate, 72%). PCA yielded three subscales: "personal continuity: care provider knows me," "personal continuity: care provider shows commitment," and "team/cross-boundary continuity." Internal consistency of the subscales ranged from 0.82 to 0.89. Interscale correlations varied between 0.42 and 0.61. The NCQ shows to be a comprehensive, reliable, and valid instrument. Further testing of reliability, construct validity, and responsiveness is needed before the NCQ can be more widely implemented. Copyright © 2011 Elsevier Inc. All rights reserved.

  14. Continuous enzyme-coupled assay for microbial transglutaminase activity.

    Oteng-Pabi, Samuel K; Keillor, Jeffrey W

    2013-10-15

    Transglutaminases (protein-glutamine:amine γ-glutamyltransferase, EC 2.3.2.13) are a family of calcium-dependent enzymes that catalyze an acyl transfer between glutamine residues and a wide variety of primary amines. When a lysine residue acts as the acyl-acceptor substrate, a γ-glutamyl-ε-lysine isopeptide bond is formed. This isopeptide bond formation represents protein cross-linking, which is critical to several biological processes. Microbial transglutaminase (mTG) is a bacterial variant of the transglutaminase family, distinct by virtue of its calcium-independent catalysis of the isopeptidic bond formation. Furthermore, mTG's promiscuity in acyl-acceptor substrate preference highlights its biocatalytic potential. The acyl-donor substrate, however, is limited in its scope; the amino acid sequences flanking glutamine residues dramatically affect substrate specificity and activity. Here, we have developed and optimized a modified glutamate dehydrogenase assay with the intention of analyzing potential high-affinity peptides. This direct continuous assay presents significant advantages over the commonly used hydroxamate assay, including generality, sensitivity, and ease of manipulation. Furthermore, we identified 7M48 (WALQRPH), a high-affinity peptide that shows greater affinity with mTG (K(M)=3 mM) than the commonly used Cbz-Gln-Gly (K(M)=58 mM), attesting to its potential for application in biocatalysis and bioconjugation.

  16. Distance learning: the future of continuing professional development.

    Science.gov (United States)

    Southernwood, Julie

    2008-10-01

    The recent development of a market economy in higher education has resulted in the need to tailor the product to the customers, namely students, employers and commissioning bodies. Distance learning is an opportunity for nurse educators and institutions to address marketing initiatives and develop a learning environment in order to enhance continuing professional development. It provides options for lifelong learning for healthcare professionals--including those working in community settings--that is effective and cost efficient. Development of continuing professional development programmes can contribute to widening the participation of community practitioners in lifelong learning, practice and role development. This paper considers the opportunities that web-based and online education programmes can provide community practitioners to promote professional skills while maintaining a work-life balance, and the role of the lecturer in successfully supporting professionals on web-based learning programmes.

    Learning science is an emerging interdisciplinary field that offers educators key insights about what happens in the brain when learning occurs. In addition to explanations about the learning process, which includes memory and involves different parts of the brain, learning science offers effective strategies to inform the planning and implementation of activities and programs in continuing education and continuing professional development. This article provides a brief description of learning, including the three key steps of encoding, consolidation and retrieval. The article also introduces four major learning-science strategies, known as distributed learning, retrieval practice, interleaving, and elaboration, which share the importance of considerable practice. Finally, the article describes how learning science aligns with the general findings from the most recent synthesis of systematic reviews about the effectiveness of continuing medical education.

    Full Text Available Holger Schmid1,21Clinic and Policlinic IV, Section of Nephrology, Munich University Hospital, Campus Innenstadt, Munich, Germany; 2KfH Nierenzentrum Muenchen Laim, Munich, GermanyBackground: Erythropoiesis-stimulating agents (ESAs are the mainstay of anemia therapy. Continuous erythropoietin receptor activator (CERA is a highly effective, long-acting ESA developed for once-monthly dosing. A multitude of clinical studies has evaluated the safety and efficiency of this treatment option for patients with renal anemia. In times of permanent financial pressure on health care systems, the cost-effectiveness of CERA should be of particular importance for payers and clinicians.Objective: To critically analyze, from the nephrologists' point of view, the published literature focusing on the cost-effectiveness of CERA for anemia treatment.Methods: The detailed literature search covered electronic databases including MEDLINE, PubMed, and Embase, as well as international conference abstract databases.Results: Peer-reviewed literature analyzing the definite cost-effectiveness of CERA is scarce, and most of the available data originate from conference abstracts. Identified data are restricted to the treatment of anemia due to chronic kidney disease. Although the majority of studies suggest a considerable cost advantage for CERA, the published literature cannot easily be compared. While time and motion studies clearly indicate that a switch to CERA could minimize health care staff time in dialysis units, the results of studies comparing direct costs are more ambivalent, potentially reflecting the differences between health care systems and variability between centers.Conclusion: Analyzed data are predominantly insufficient; they miss clear evidence and have to thus be interpreted with great caution. In this day and age of financial restraints, results from well-designed, head-to-head studies with clearly defined endpoints have to prove whether CERA therapy can

    Innovations in health care call for fresh approaches to continuing nursing education that support lateral relationships, teamwork, and collaboration. To foster this transformation, we devised the following education principles: Everyone teaches, everyone learns; embrace probability; information is dynamic; and trust professionals to practice professionally. These principles guided the development of seven independent, practice-specific, evidence-based continuing nursing education programs totaling 21.5 contact hours for casual-status nurses who practiced as childbirth educators. The programs were popular, promoted teamwork, and increased communication about evidence-based practice.

  8. Recognition of Human Activities Using Continuous Autoencoders with Wearable Sensors

    Directory of Open Access Journals (Sweden)

    Lukun Wang

    2016-02-01

    Full Text Available This paper provides an approach for recognizing human activities with wearable sensors. The continuous autoencoder (CAE as a novel stochastic neural network model is proposed which improves the ability of model continuous data. CAE adds Gaussian random units into the improved sigmoid activation function to extract the features of nonlinear data. In order to shorten the training time, we propose a new fast stochastic gradient descent (FSGD algorithm to update the gradients of CAE. The reconstruction of a swiss-roll dataset experiment demonstrates that the CAE can fit continuous data better than the basic autoencoder, and the training time can be reduced by an FSGD algorithm. In the experiment of human activities’ recognition, time and frequency domain feature extract (TFFE method is raised to extract features from the original sensors’ data. Then, the principal component analysis (PCA method is applied to feature reduction. It can be noticed that the dimension of each data segment is reduced from 5625 to 42. The feature vectors extracted from original signals are used for the input of deep belief network (DBN, which is composed of multiple CAEs. The training results show that the correct differentiation rate of 99.3% has been achieved. Some contrast experiments like different sensors combinations, sensor units at different positions, and training time with different epochs are designed to validate our approach.

    To this day, the concept of continuous bioprocessing has been applied mostly to the manufacture of molecular biologics such as proteins, growth factors, and secondary metabolites with biopharmaceutical uses. The present work now sets to explore the potential application of continuous bioprocess methods to source large numbers of human adherent cells with potential therapeutic value. To this purpose, we developed a smart multifunctional surface coating capable of controlling the attachment, proliferation, and subsequent self-detachment of human corneal stromal cells. This system allowed the maintenance of cell cultures under steady-state growth conditions, where self-detaching cells were continuously replenished by the proliferation of those remaining attached. This facilitated a closed, continuous bioprocessing platform with recovery of approximately 1% of the total adherent cells per hour, a yield rate that was maintained for 1 month. Moreover, both attached and self-detached cells were shown to retain their original phenotype. Together, these results represent the proof-of-concept for a new high-throughput, high-standard, and low-cost biomanufacturing strategy with multiple potentials and important downstream applications.

    assessing relevance and effectiveness of care/educational technology in the form of "storytelling" as a strategy in the cultivation of active ageing (AA) for elderly users of a Basic Health Unit (BHU), from the Amazon region. convergent care research (CCR) held in a BHU in Belém, state of Pará, with eight elderly ladies for testing this technology. An active ageing assessment questionnaire and WHOQOL-BREF - quality of life assessment were applied. After training with a view to continuing education, elderly ladies told stories for an audience that addressed the question: "What did you learn from it for your life?" tThe popular stories elicited reactions from which the following categories emerged: solidarity; respect for the other; imagination, dreams, hopes and culture of the Amazonian. This practice had a positive result, producing changes in the quality of life of the elderly, particularly in the psychological domain. "storytelling" proved to be an innovative technology, a relevant and effective resource in health education, especially for active ageing.

  14. Visual working memory continues to develop through adolescence

    2015-05-01

    Full Text Available The capacity of visual working memory (VWM refers to the amount of visual information that can be maintained in mind at once, readily accessible for ongoing tasks. In healthy young adults, the capacity limit of VWM corresponds to about three simple objects. While some researchers argued that VWM capacity becomes adult-like in early years of life, others claimed that the capacity of VWM continues to develop beyond middle childhood. Here we assessed whether VWM capacity reaches adult levels in adolescence. Using an adaptation of the visual change detection task, we measured visual working memory capacity estimates in 13 year-olds, 16-year-olds, and young adults. We tested whether the capacity estimates observed in early or later years of adolescence were comparable to the estimates obtained from adults. Our results demonstrated that the capacity of VWM continues to develop throughout adolescence, not reaching adult levels even in 16 year-olds. These findings suggest that VWM capacity displays a prolonged development, similar to the protracted trajectories observed in various other aspects of cognition.

    Adiabatic Demagnetization Refrigeration (ADR) does not use working fluids contrary to conventional refrigerators that make use of the fluid density difference, which leads to superiority of the ADR under the weak gravity condition. In this study, we developed a continuous ADR system to provide constant cooling temperatures {approx}0.1 K. The system consists of four stages of magnetic materials and magnets cascaded with heat switches. The magnetic materials CPA and GdLiF{sub 4} are used for 3 stages between 0.1K and 1.4 K, and single stage between 1.4 K and 4 K, respectively. Passive heat switches are used for the stages > 0.3 K and a superconducting heat switch is used for the continuous stage at {approx}0.1 K. A G-M cycle cooler with a 100 V compressor unit is used to cool the ADR and cryostat shieldings. Total mass of flight model is less than 60 kg. Cooling tests with Transition Edge Sensor on the ground showed that the ADR provided continuous cooling temperatures between 105 mK and 120 mK and it successfully operated the TES. Airborne flight experiments confirmed the ability of the cooling system under the mili-gravity condition. The experimental results showed that the ADR could provide stable temperature under the weak gravity, however, strong vibrations coming from turbulence or takeoff affected to the stability of ADR cycle.

    2017-08-01

    Continuing medical education (CME) has the power and capacity to address many challenges in the health care environment, from clinician well-being to national imperatives for better health, better care, and lower cost. Health care leaders who recognize the strategic value of education and engage their people in education can expect a meaningful return on their investment-not only in terms of the quality and safety of their clinicians' work but also in the spirit and cohesiveness of the clinicians who work at their institution. To optimize the benefits of education, clinical leaders need to think of accredited CME as the professional development vehicle that can help them drive change and achieve goals, in consort with quality improvement efforts, patient safety projects, and other systems changes. An empowered CME program, with its multiprofessional scope and educational expertise, can contribute to initiatives focused on both clinical and nonclinical areas, such as quality and safety, professionalism, team communication, and process improvements. In this Invited Commentary, the author describes principles and action steps for aligning leadership and educational strategy and urges institutional leaders to embrace the continuing professional development of their human capital as an organizational responsibility and opportunity and to view engagement in education as an investment in people.

    2015-05-01

    A nursing career can last for more than 40 years, during which continuing professional development is essential. Nurses participate in a variety of learning activities that correspond with their developmental motives. Lifespan psychology shows that work-related motives change with age, leading to the expectation that motives for continuing professional development also change. Nevertheless, little is known about nurses' continuing professional development strategies in different age groups. To explore continuing professional development strategies among younger, middle-aged, and older nurses. A qualitative study using semi-structured interviews, from a biographical perspective. Data were analysed using a vertical process aimed at creating individual learning biographies, and a horizontal process directed at discovering differences and similarities between age groups. Twenty-one nurses in three age groups from general and academic hospitals in the Netherlands. In all age groups, daily work was an important trigger for professional development on the ward. Performing extra or new tasks appeared to be an additional trigger for undertaking learning activities external to the ward. Learning experiences in nurses' private lives also contributed to their continuing professional development. Besides these similarities, the data revealed differences in career stages and private lives, which appeared to be related to differences in continuing professional development strategy; 'gaining experience and building a career' held particularly true among younger nurses, 'work-life balance' and 'keeping work interesting and varied' to middle-aged nurses, and 'consistency at work' to older nurses. Professional development strategies can aim at performing daily patient care, extra tasks and other roles. Age differences in these strategies appear to relate to tenure, perspectives on the future, and situations at home. These insights could help hospitals to orientate continuing

    Alabdulkader, Balsam; Leat, Susan Jennifer

    Near visual acuity is an essential measurement during an oculo-visual assessment. Short duration continuous text reading charts measure reading acuity and other aspects of reading performance. There is no standardized version of such chart in Arabic. The aim of this study is to create sentences of equal readability to use in the development of a standardized Arabic continuous text reading chart. Initially, 109 Arabic pairs of sentences were created for use in constructing a chart with similar layout to the Colenbrander chart. They were created to have the same grade level of difficulty and physical length. Fifty-three adults and sixteen children were recruited to validate the sentences. Reading speed in correct words per minute (CWPM) and standard length words per minute (SLWPM) was measured and errors were counted. Criteria based on reading speed and errors made in each sentence pair were used to exclude sentence pairs with more outlying characteristics, and to select the final group of sentence pairs. Forty-five sentence pairs were selected according to the elimination criteria. For adults, the average reading speed for the final sentences was 166 CWPM and 187 SLWPM and the average number of errors per sentence pair was 0.21. Childrens' average reading speed for the final group of sentences was 61 CWPM and 72 SLWPM. Their average error rate was 1.71. The reliability analysis showed that the final 45 sentence pairs are highly comparable. They will be used in constructing an Arabic short duration continuous text reading chart.

    The critical role of continuing professional development (CPD) in supporting delivery of patient care of the highest quality and safety is receiving significant attention in the current era of monumental change. CPD is essential in efforts to ensure effectiveness of new models of health care delivery, improve outcomes and value in health care, address external regulations, and foster patient engagement. The unique features of CPD; the use of special mastery-based teaching, learning, and assessment methods, and other special interventions to promote excellence; and direct involvement of a variety of key stakeholders differentiate CPD from undergraduate medical education and graduate medical education. The needs of procedural specialties relating to CPD are different from those of primary care disciplines and require special attention for the greatest impact. Simulation-based education and training can be very useful in CPD aimed at improving outcomes and promoting patient safety. Preceptoring, proctoring, mentoring, and coaching should be used routinely to address specific needs in CPD. Distinct CPD strategies are necessary for retraining, reentry, and remediation. Participation in CPD programs can be encouraged by leveraging the joy of learning, which should drive physicians and surgeons to strive continually to be the best in their professional work.

    In order to better understand the endocrine aberrations related to abnormal metamorphic pigmentation that appear in flounder larvae reared in tanks, this study examined the effects of continuous 24-h illumination (LL) through larval development on the expression of tyrosine hydroxylase-1 (th1), proopiomelanocortin (pomc), α-melanophore-stimulating hormone (α-MSH) and melanin concentrating hormone (MCH), which are known to participate in the control of background adaptation of body color. We observed two conspicuous deviations in the endocrine system under LL when compared with natural light conditions (LD). First, LL severely suppressed th1 expression in the dopaminergic neurons in the anterior diencephalon, including the suprachiasmatic nucleus (SCN). Second, pomc and α-MSH expression in the pars intermedia melanotrophs was enhanced by LL. Skin color was paler under LL than LD before metamorphic pigmentation, and abnormal metamorphic pigmentation occurred at a higher ratio in LL. We therefore hypothesize that continuous LL inhibited dopamine synthesis in the SCN, which resulted in up-regulation of pomc mRNA expression in the melanotrophs. In spite of the up-regulation of pomc in the melanotrophs, larval skin was adjusted to be pale by MCH which was not affected by LL. Accumulation of α-MSH in the melanotrophs is caused by uncoupling of α-MSH synthesis and secretion due to inhibitory role of MCH on α-MSH secretion, which results in abnormal metamorphic pigmentation by affecting differentiation of adult-type melanophores. Our data demonstrate that continuous illumination at the post-embryonic stage has negative effects on the neuroendocrine system and pituitary in flounder. Copyright © 2012 Elsevier Inc.

    2012-02-01

    Based on a review of 64 published reports, this article addresses the implications of current research for the further development of the Family Management Style Framework (FMSF). Articles are published in 46 different journals, including 13 in nursing and 12 in interdisciplinary outlets. Most studies are based on samples of less than 50 individuals. The review provides continuing support for the 8 dimensions of the framework, with between 8 and 16 reports supporting the relevance of each. Changes to the sociocultural component of the framework are proposed as well as wording changes to reflect the broader applicability of the framework. The family's social network, health care and education professionals, and resources predominate as key influences on family management.

    The ATLAS software infrastructure facilitates efforts of more than 1000 developers working on the code base of 2200 packages with 4 million lines of C++ and 1.4 million lines of python code. The ATLAS offline code management system is the powerful, flexible framework for processing new package versions requests, probing code changes in the Nightly Build System, migration to new platforms and compilers, deployment of production releases for worldwide access and supporting physicists with tools and interfaces for efficient software use. It maintains multi-stream, parallel development environment with about 70 multi-platform branches of nightly releases and provides vast opportunities for testing new packages, for verifying patches to existing software and for migrating to new platforms and compilers. The system evolution is currently aimed on the adoption of modern continuous integration (CI) practices focused on building nightly releases early and often, with rigorous unit and integration testing. This paper describes the CI incorporation program for the ATLAS software infrastructure. It brings modern open source tools such as Jenkins and GitLab into the ATLAS Nightly System, rationalizes hardware resource allocation and administrative operations, provides improved feedback and means to fix broken builds promptly for developers. Once adopted, ATLAS CI practices will improve and accelerate innovation cycles and result in increased confidence in new software deployments. The paper reports the status of Jenkins integration with the ATLAS Nightly System as well as short and long term plans for the incorporation of CI practices.

    To design and implement a continuing professional development (CPD) program for Cambodian ophthalmologists. Partnering (twinning) between the Royal Australian and New Zealand College of Ophthalmologists (RANZCO) and the Cambodian Ophthalmological Society (COS). Practicing ophthalmologists in Cambodia. A conjoint committee comprising 4 ophthalmologists from RANZCO and 3 ophthalmologists from COS was established, supported by a RANZCO administrative team experienced in CPD administration. CPD requirements and recording were adapted from the RANZCO CPD framework. Cambodian ophthalmologists were surveyed during program implementation and after handover to COS. At the end of the 3-year program at handover to COS, a CPD program and online recording system was established. All 47 (100%) practicing ophthalmologists in Cambodia were registered for CPD, and 21/47 (45%) were actively participating in the COS CPD program online recording. Surveys of attitudes toward CPD demonstrated no significant change. Partnering was moderately effective in establishing a CPD program for Cambodian ophthalmologists. Uptake of CPD may have been limited by lack of a requirement for CPD for continuing medical licensure in Cambodia. Follow-up will be necessary to demonstrate CPD program longevity.

    2008-04-15

    The Department of Energy (DOE), National Energy Technology Center (NETL), has initiated a strategic plan for the development of advanced technologies needed to design and build fossil fuel plants with very high efficiency and environmental performance. These plants, referred to as 'Vision 21' and FutureGen programs by DOE, will produce electricity, chemicals, fuels, or a combination of these products, and possibly secondary products such as steam/heat for industrial use. MA956 is a prime candidate material being considered for a high temperature heat exchanger in the 'Vision 21' and FutureGen programs. This material is an oxide dispersion strengthened (ODS) alloy; however, there are some gaps in the data required to commit to the use of these alloys in a full-size plant. To fill the technology gaps for commercial production and use of the material for 'Advanced Power Generation Systems' this project has performed development activity to significant increase in circumferential strength of MA956 as compared to currently available material, investigated bonding technologies for bonding tube-to-tube joints through joining development, and performed tensile, creep and fire-side corrosion tests to validate the use and fabrication processes of MA956 to heat exchanger tubing applications. Development activities within this projected has demonstrated increased circumferential strength of MA956 tubes through flow form processing. Of the six fabrication technologies for bonding tube-to-tube joints, inertia friction welding (IFW) and flash butt welding (FBW) were identified as processes for joining MA956 tubes. Tensile, creep, and fire-side corrosion test data were generated for both base metal and weld joints. The data can be used for design of future systems employing MA956. Based upon the positive development activities, two test probes were designed and fabricated for field exposure testing at 1204 C ({approx}2200 F) flue gas. The probes

    Competent renal dietitians are crucial for better patient compliance and clinical outcomes, specifically in critical settings. The aim of this study was to develop and evaluate an evidence-based course in renal dietetics for dietitians working in health care systems where dietetic specialization is absent. Fifteen licensed dietitians working with hemodialysis patients in Lebanon were randomly recruited to participate in the course. The latter was developed by the study's primary investigator, according to evidence-based practice guidelines, and focused on all aspects of renal nutrition. Total course duration was 28 hours spread over a 2 month period. Dietitians' knowledge in renal nutrition was tested pre- and post-training through a 23-item questionnaire; the total score was expressed in percentage (insufficient knowledge). Paired-samples t test was used for statistical analysis. Overall knowledge of the dietitians significantly improved post-training and reached satisfactory levels (pre: 38.75 ± 17.20%, post: 62.08 ± 21.85%). Sub-analysis of the change in the knowledge showed significant and satisfactory improvement only in 3 topics: 1) correct body weight use in calculations, 2) energy estimation method and 3) phosphorus management. Knowledge in the fluid management significantly improved but did not achieve a satisfactory level. The course significantly improved dietitians' knowledge in renal nutrition. If adopted as part of the continuing education of dietitians in countries that lack dietetic specializations, it may serve the first step towards improving health care practice.

    In this work, we study a dark dune field on the western side of Herschel crater, a 300 km diameter impact basin located near the Martian equator (14.4°S, 130°E), where the ripple and dune motion reflects the actual atmospheric wind conditions. We develop an integrated analysis using (1) automated ripple mapping that yields ripple orientations and evaluates the spatial variation of actual atmospheric wind conditions within the dunes, (2) an optical cross-correlation that allows us to quantify an average ripple migration rate of 0.42 m per Mars year, and (3) mesoscale climate modeling with which we compare the observed aeolian changes with modeled wind stresses and directions. Our observations are consistent with previous work [1] [2] that detected aeolian activity in the western part of the crater. It also demonstrates that not only are the westerly Herschel dunes movable, but that predominant winds from the north are able to keep the ripples and dunes active within most (if not all) of Herschel crater in the current atmospheric conditions.

  18. Development and implementation of a business continuity management risk index.

    Science.gov (United States)

    Kadar, Michael

    This paper will present the building blocks for developing and implementing the BCM risk index; whether it is used as a comprehensive metric for risk or preparedness. This paper introduces the concept of a business continuity management (BCM) risk index--a comprehensive metric that measures and reports the status of the primary 'intended outcome' of the BCM programme to top management. In addition to measuring the primary programme output,;the BCM risk index can be used to demonstrate the overall value of the BCM programme to executive management. This is accomplished because the BCM risk index allows quantitative measurement of current risk levels and their comparison with established risk tolerances. The BCM Risk Index can provide executive management with reports on the risk level of individual business units, departments, subsidiaries or the enterprise in a way that drives both risk management and BCM initiatives. The name 'risk index' can be misleading, however. The BCM risk index concept can also be used to measure preparedness levels. In fact, implementation at DTE Energy has resulted in calling it the 'preparedness index', which is used to measure and report preparedness levels rather than risk levels.

  19. Continued Development of a Soft Gamma-Ray Concentrator

    Science.gov (United States)

    Bloser, Peter

    We propose to continue our development of a concept for a soft gamma-ray (E > 100 keV) concentrator using thin-film multilayer structures. Alternating layers of low- and high-density materials will channel soft gamma-ray photons via total external reflection. A suitable arrangement of bent structures will then concentrate the incident radiation to a point. Gamma-ray optics made in this way offer the potential for soft gamma-ray telescopes with focal lengths of less than 10 m, removing the need for formation flying spacecraft and opening the field up to balloon-borne instruments. Under previous APRA funding we have been investigating methods for efficiently producing such multilayer structures and modeling their performance. We now propose to pursue magnetron sputtering (MS) techniques to quickly produce structures with the required smoothness and thickness, to measure their channeling efficiency and compare with calculations, and to design a "lens" with optimized bandpass and throughput and predict its scientific performance. If successful, this work will confirm that this innovative optics concept is suitable for a balloon-born soft gamma-ray telescope with unprecedented sensitivity.

    Full Text Available In this work, the development of continuous deglycerolisation (CD reactor for ethyl ester production was investigated to improve the ethyl ester conversion. The device to assist separation of glycerol, in the CD unit, integrates transesterification (mixing zone and separation (settling zone into one unit. For reversible transesterification, removing glycerol during reaction can drive the equilibrium to the product side in order to achieve high conversion. Two models of device to assist separation of glycerol have been carried out to investigate the suitable conditions for ethyl ester production. Results showed that the fin-type model could separate higher amount of glycerol from the reaction system in order to achieve high transesterification conversion. The suitable conditions found in this study were: molar ratio of oil to ethanol of 1:5, KOCH3 concentration of 1.6 %wt. retention time of 15 min and reaction temperature of 70°C. At these conditions, ethyl ester’s purity and yield were 97.3%wt. and 92.0%wt., respectively. In addition, the fuel properties of the final ethyl ester product met the biodiesel standard for methyl ester which specified by Department of Energy Business.

    In a cyclical heat load environment such as low Lunar orbit, a spacecraft's radiators are not sized to meet the full heat rejection demands. Traditionally, a supplemental heat rejection device (SHReD) such as an evaporator or sublimator is used to act as a "topper" to meet the additional heat rejection demands. Utilizing a Phase Change Material (PCM) heat exchanger (HX) as a SHReD provides an attractive alternative to evaporators and sublimators as PCM HX's do not use a consumable, thereby leading to reduced launch mass and volume requirements. In continued pursuit of water PCM HX development two full-scale, Orion sized water-based PCM HX's were constructed by Mezzo Technologies. These HX's were designed by applying prior research on freeze front propagation to a full-scale design. Design options considered included bladder restraint and clamping mechanisms, bladder manufacturing, tube patterns, fill/drain methods, manifold dimensions, weight optimization, and midplate designs. Two units, Units A and B, were constructed and differed only in their midplate design. Both units failed multiple times during testing. This report highlights learning outcomes from these tests and are applied to a final sub-scale PCM HX which is slated to be tested on the ISS in early 2017.

  2. Coaching Experts: Applications to Surgeons and Continuing Professional Development.

    2018-02-01

    Surgery is a science and an art, which is mastered through years of training and refined by the accumulation of individual experience and preference. Continuing professional development (CPD) is a concept that emphasizes a self-directed approach to education. Coaching is a process that leads to increased utilization of a person's current skills and resources without counselling or advising. Coaching in surgery could be used to facilitate and optimize feedback and reflection, thus enhancing performance and outcomes through elite performance of an operative procedure. Therefore, it can be applied under the umbrella of CPD. Ultimately also emphasizing that better quality surgery is not necessarily purely based on technical outcomes, it is a combination of both technical and nontechnical practice. Coaching of surgeons is a conceptually formidable tool in the successful implementation of effective CPD programs. CPD currently provides an opportunity for surgeons to gain access to constantly evolving medical knowledge and technique; however, there is no accountability to its understanding or implementation. Coaches have the potential to provide confidential appraisal and feedback in a constructive approach with the aim to eliminate any barriers to the transfer of technique and knowledge.

  3. Development and validation of continuous energy adjoint-weighted calculations

    International Nuclear Information System (INIS)

    Truchet, Guillaume

    2015-01-01

    A key issue in nowadays Reactor Physics is to propagate input data uncertainties (e.g. nuclear data, manufacturing tolerances, etc.) to nuclear codes final results (e.g. k(eff), reaction rate, etc.). In order to propagate uncertainties, one typically assumes small variations around a reference and evaluates at first sensitivity profiles. Problem is that nuclear Monte Carlo codes are not - or were not until very recently - able to straightforwardly process such sensitivity profiles, even thought they are considered as reference codes. First goal of this PhD thesis is to implement a method to calculate k(eff)-sensitivity profiles to nuclear data or any perturbations in TRIPOLI-4, the CEA Monte Carlo neutrons transport code. To achieve such a goal, a method has first been developed to calculate the adjoint flux using the Iterated Fission Probability (IFP) principle that states that the adjoint flux at a given phase space point is proportional to the neutron importance in a just critical core after several power iterations. Thanks to our developments, it has been made possible, for the fist time, to calculate the continuous adjoint flux for an actual and complete reactor core configuration. From that new feature, we have elaborated a new method able to forwardly apply the exact perturbation theory in Monte Carlo codes. Exact perturbation theory does not rely on small variations which makes possible to calculate very complex experiments. Finally and after a deep analysis of the IFP method, this PhD thesis also reproduces and improves an already used method to calculate adjoint weighted kinetic parameters as well as reference migrations areas.

    To quantify and compare energy utilization associated with prolonged sitting alone, or interrupted with regular activity breaks and/or an additional bout of continuous physical activity. Thirty six adults (11 males, BMI 24.1 ± 4.6) completed four interventions: (1) prolonged sitting (SIT), (2) sitting with 2-min of walking every 30 min (RAB), (3) prolonged sitting with 30-min of continuous walking at the end of the day (SIT + PA), (4) a combination of the activities in (2) and (3) above (RAB + PA). All walking was at a speed and incline corresponding to 60% V̇O 2max . Energy utilization over 7 h for each intervention was estimated using indirect calorimetry. Compared to SIT, SIT + PA increased total energy utilization by 709 kJ (95% CI 485-933 kJ), RAB by 863 kJ (95% CI 638-1088 kJ), and RAB + PA by 1752 kJ (95% CI 1527-1927 kJ) (all p energy utilization between SIT + PA and RAB, however, post-physical activity energy utilization in RAB was 632 kJ greater than SIT + PA (95% CI 561-704 kJ; p energy utilization compared to a single bout of continuous activity; however the total energy utilization is similar. Combining activity breaks with a longer continuous bout of activity will further enhance energy utilization, and in the longer term, may positively affect weight management of a greater magnitude than either activity pattern performed alone.

    1979-01-01

    A commercial Czochralski crystal growing furnace was converted to a continuous growth facility by installation of a small, in-situ premelter with attendant silicon storage and transport mechanisms. Using a vertical, cylindrical graphite heater containing a small fused quartz test tube linear from which the molten silicon flowed out the bottom, approximately 83 cm of nominal 5 cm diamter crystal was grown with continuous melt addition furnished by the test tube premelter. High perfection crystal was not obtained, however, due primarily to particulate contamination of the melt. A major contributor to the particulate problem was severe silicon oxide buildup on the premelter which would ultimately drop into the primary melt. Elimination of this oxide buildup will require extensive study and experimentation and the ultimate success of continuous Czochralski depends on a successful solution to this problem. Economically, the continuous Czochralski meets near-term cost goals for silicon sheet material.

    1978-01-01

    A Czochralski crystal growing furnace was converted to a continuous growth facility by installation of a premelter to provide molten silicon flow into the primary crucible. The basic furnace is operational and several trial crystals were grown in the batch mode. Numerous premelter configurations were tested both in laboratory-scale equipment as well as in the actual furnace. The best arrangement tested to date is a vertical, cylindrical graphite heater containing small fused silicon test tube liner in which the incoming silicon is melted and flows into the primary crucible. Economic modeling of the continuous Czochralski process indicates that for 10 cm diameter crystal, 100 kg furnace runs of four or five crystals each are near-optimal. Costs tend to asymptote at the 100 kg level so little additional cost improvement occurs at larger runs. For these conditions, crystal cost in equivalent wafer area of around $20/sq m exclusive of polysilicon and slicing was obtained.

    2015-06-01

    Full Text Available This paper presents the main results of a Franco-Brazilian Research project entitled "Work, Innovation and Development". The aim is to conceptually consider work activity within sustainable development, and to contribute methodologically towards developing strategies for designing sustainable work systems. After a brief description of the factors and the dimensions that have contributed to the creation of ideas on sustainable development, we will put forward two main approaches for understanding work activity within the context of sustainability, these being: the durability of work activity and the development of work activities for sustainable development.

    Sceloporus bicanthalis is a viviparous lizard that lives at higher elevations in Mexico. Adult male S. bicanthalis were collected (n = 36) from the Nevado de Toluca, Mexico (elevation is 4200 m) during August to December, 2007 and January to July, 2008. Testes were extracted, fixed in Trumps, and dehydrated in a graded series of ethanol. Tissues were embedded, sectioned (2 μm), stained, and examined via a light microscope to determine the spermatogenic developmental strategy of S. bicanthalis. In all months examined, the testes were spermiogenically active; based on this, plus the presence of sperm in the lumina of seminiferous tubules, we inferred that S. bicanthalis had year-round or continuous spermatogenesis, unlike most reptiles that occupy a temperate or montane habitat. It was recently reported that seasonally breeding reptiles had a temporal germ cell development strategy similar to amphibians, where germ cells progress through spermatogenesis as a single population, which leads to a single spermiation event. This was much different than spatial development within the testis of other derived amniotes. We hypothesized that germ cell development was temporal in S. bicanthalis. Therefore, we wanted to determine whether reptiles that practice continuous spermatogenesis have a mammalian-like spatial germ cell development, which is different than the typical temperate reptile exhibiting a temporal development. In the present study, S. bicanthalis had a temporal development strategy, despite its continuous spermatogenic cycle, making them similar to tropical anoles. Copyright © 2011 Elsevier Inc.

    De Fiore, Luca

    2012-01-01

    This paper considers the impact of the new information environment on the scientific communication. Reading behavior changes: today, we browse, scan, watch, receive an impression of something. The new reading habits are not simply determined by the new tools; they are rather influenced by the need to produce and share data and information, using personalized and mobile devices. Also the content formats change: researchers, clinicians, and nurses produce texts, figures, tables, photos, videos, tweets, blog posts and they share them to readers that have to collect, appraise, recombine and - most importantly - contextualize the information. This "continuous partial production" is consistent with a "continuous partial utilization" of data; this is a risk, but it is also an opportunity. On the one side, we risk a self-referential, individualized learning process; on the other side, we can enjoy the extraordinary chance to build a "shared learning environment", able to give a comprehensive solution to the challenges experienced by the health systems. Medical journals survive as valuable media to organize data and information; the new social web tools should support the traditional publishing patterns, to enhance the sharing of information, to help the appraisal of data, and to move forward new communities of learners.

    It has been found that almost 80 % of the incidents and accidents occurred recently, such as the Fukushima Daiichi disaster and Domestic SBO accident etc. were analyzed to be caused from human errors. (IAEA NES NG-G-2.1) Which strongly claims the importance of the safety culture system. Accordingly, it should be away from a cursory approach like one-off field survey or Snap shop which were being conducted at present for the continued improvement of safety culture. This study introduces an analytical methodology which approaches the generic form of the safety both consciously and unconsciously expressed with behavior, thoughts, and attitude etc. This study was implemented only for open materials such as Inspection report, incidents and accidents reports, QA documents because of the limitation in accessibility to data. More effective use with securing operational data will be possible in future

    In a 2-year project, we developed and trialled a mode of lecturing professional development amongst staff in our department of mathematics. Theoretically grounded in Schoenfeld's resources, orientations, and goals (ROG) model of teacher action, a group met regularly to discuss both the video excerpts of themselves lecturing along with written pre- and post-lecture statements of their "ROGs". We found evidence of improved teaching performance but more interestingly, identified key aspects of our practice and of undergraduate mathematics that received repeated attention and developed further theoretical insight into lecturer behaviour in mathematics. The trial has been successful enough to be expanded into further groups that now constitute a professional development culture within our department.

    A summary of financial data for the uranium spot market in November 1996 is provided. Price ranges for the restricted and unrestricted markets, conversion, and separative work are listed, and total market volume and new contracts are noted. Transactions made are briefly described. Deals made and pending in the spot concentrates, medium and long-term, conversion, and markets are listed for U.S. and non-U.S. buyers. Spot market activity increased in November with just over 1.0 million lbs of U3O8 equivalent being transacted compared to October's total of 530,000 lbs of U3O8 equivalent. The restricted uranium spot market price range slipped from $15.50-$15.70/lb U3O8 last month to $14.85/lb - $15.25/lb U3O8 this month. The unrestricted uranium spot market price range also slipped to $14.85/lb - $15.00/lb this month from $15.00/lb - $15.45/lb in October. Spot prices for conversion and separative work units remained at their October levels

    All mammals previously studied take maximal rest or sleep after birth, with the amount gradually decreasing as they grow to adulthood, and adult fruitflies and rats die if they are forcibly deprived of sleep. It has therefore been assumed that sleep is necessary for development and serves a vital function in adults. But we show here that, unlike terrestrial mammals, killer-whale and bottlenose-dolphin neonates and their mothers show little or no typical sleep behaviour for the first postpartum month, avoiding obstacles and remaining mobile for 24 hours a day. We find that neonates and their mothers gradually increase the amount of time they spend resting to normal adult levels over a period of several months, but never exceed these levels. Our findings indicate either that sleep behaviour may not have the developmental and life-sustaining functions attributed to it, or that alternative mechanisms may have evolved in cetaceans.

    Strategies are needed to assure essential nonclinical competencies, such as leadership, can be gained using a continuing professional development (CPD) framework. The objective of this study was to explore student pharmacists' utilization and perceived effectiveness of a CPD tool for leadership development in an elective course. Students completed 2 CPD cycles during a semester-long leadership elective using a CPD tool. A questionnaire was used to measure students' perceptions of utility, self-efficacy, and satisfaction in completing CPD cycles when using a tool to aid in this process. The CPD tool was completed twice by 7 students. On average, students spent nearly 5 hours per CPD cycle. More than half (57.1%) scored themselves as successful or very successful in achieving their learning plans, and most (71.4%) found the tool somewhat useful in developing their leadership skills. Some perceived that the tool provided a systematic way to engage in leadership development, whereas others found it difficult to use. In this pilot study, most student pharmacists successfully achieved a leadership development plan and found the CPD tool useful. Providing students with more guidance may help facilitate use and effectiveness of CPD tools. There is a need to continue to develop and refine tools that assist in the CPD of pharmacy practitioners at all levels. Copyright © 2013 Elsevier Inc. All rights reserved.

    Full Text Available Introduction. The system of continued professional education in modern Russia is aimed at raising the level of professional workers’ ability for competition at the global vocational market. Among the most required competences we put an emphasis on the ability for efficient communication in the native and foreign languages pursuing social, cultural and professional interaction. The practical experience proves that students of various courses of study within the system of continued professional education have difficulties while communicating in a foreign language because of a low level of their foreign language communication competence that is based on ability for decoding and producing a discourse. Aim. The article considers the factors to develop students’ ability for decoding and producing a discourse in the format of reflexive positional discussion. Methodology and research methods. Development of the advanced and high level of foreign language competence is possible via introduction of institutional discursive practices into the educational process. Development of foreign language competence in the system of continued professional education is being discussed from the point of synergy of pedagogical science and applied linguistics. System-synergetic, communicative-activity, discursive and technological approaches have been chosen as the methodological base to develop the system of criteria of students’ preparedness and ability to communicate in a foreign language. Methods of analysis and synthesis have been used during the work as well. Results and scientific novelty. The materials presented in the publication make a contribution to the theory and methodology of continued professional education regarding effective experts’ foreign language mastering, and skills acquisition for the most productive interpersonal and professional-oriented communication.

    To perform initial validation of a continuous motion monitoring technology that can potentially be used as a risk assessment tool to determine risk for developing pressure ulcers (PUs). We have used the EverOn system (Earlysense LTD, Ramat Gan, Israel) as a bed movement and activity monitor. The EverOn is a contactless continuous measurement system based on a piezoelectric sensor that is placed under the patient's mattress. The study was a noninterventional study performed in 2 medical departments in 2 medical centers. Recorded movement data from enrolled patients were retrospectively analyzed, and patients were assigned a motion level score. Motion scores for the first night of hospitalization were correlated with the Norton scale as calculated per patient on admission. Overall, 116 patients were included in the study from the 2 sites. Motion score was significantly different between the PU risk groups as determined by the Norton scale (10.7 ± 6.2 for low, 5.4 ± 4.9 for intermediate, and 1.6 ± 3.2 for high risk; P risk for developing PU (≤14), the sensitivity of the motion score was 85%, and the specificity was 93%. With regard to individual risk components, we found that activity, mobility, physical condition, and incontinence correlated highly with motion level. The high correlation between the EverOn motion score and the calculated Norton scale indicates the potential of this technology to serve as a risk assessment tool for the development of PUs.

    A continuous active sampling method was compared to continuous passive and discrete sampling methods for the sampling of trace organic compounds (TOCs) in water. Results from each method are compared and contrasted in order to provide information for future investigators to use while selecting appropriate sampling methods for their research. The continuous low-level aquatic monitoring (CLAM) sampler (C.I.Agent® Storm-Water Solutions) is a submersible, low flow-rate sampler, that continuously draws water through solid-phase extraction media. CLAM samplers were deployed at two wastewater-dominated stream field sites in conjunction with the deployment of polar organic chemical integrative samplers (POCIS) and the collection of discrete (grab) water samples. All samples were analyzed for a suite of 69 TOCs. The CLAM and POCIS samples represent time-integrated samples that accumulate the TOCs present in the water over the deployment period (19–23 h for CLAM and 29 days for POCIS); the discrete samples represent only the TOCs present in the water at the time and place of sampling. Non-metric multi-dimensional scaling and cluster analysis were used to examine patterns in both TOC detections and relative concentrations between the three sampling methods. A greater number of TOCs were detected in the CLAM samples than in corresponding discrete and POCIS samples, but TOC concentrations in the CLAM samples were significantly lower than in the discrete and (or) POCIS samples. Thirteen TOCs of varying polarity were detected by all of the three methods. TOC detections and concentrations obtained by the three sampling methods, however, are dependent on multiple factors. This study found that stream discharge, constituent loading, and compound type all affected TOC concentrations detected by each method. In addition, TOC detections and concentrations were affected by the reporting limits, bias, recovery, and performance of each method.

In the article on the material of sociological research «The Continuing Education and the Social Well-being» conducted by the Department of social problems IEIE RAS SB, studied educational behavior, value assessment and motivation of continuing education among the economically active population of the region, compares the educational and professional potential of different groups of urban and rural population in two generations «youth - non-youth». «Youth» refers to the population aged 16-30 years, «non-youth» - a population of 31 to 45 years. The research problem that directed this research, is the lack of informed knowledge about the role of continuing education in the formation of human development of young people in different socio-territorial conditions. Amid quite a mass we of equipment for both urban and rural youth, the factor of computer and digital devices plays a role in the inclusion of young adults in continuing education. It was found a direct link of dissatisfaction about continuing education with lack of access to information technology (laptop, home Internet, digital office equipment, etc. and with low material wellbeing of the family. Along with the importance of information technology in continuing education, young adults still considers the most preferred forms of supplementary professional education (hereinafter SPE activities in organized courses with qualified teachers and methods. Differences in attitudes to supplementary professional education (SPE between urban and rural youth are identified, first, by less involvement in the real educational activity (in particular, in formal education, compensated, however, by large intentions plans to engage in continuing education.

    While all physicians must continue to learn new knowledge through their careers, their post-training continuing professional development (CPD) has received less attention. Problems include lack of support for physicians, frequent deviations from best practices such as mandatory participation, focus on community need, and clear conflicts of interest amongst providers. Additionally, specialists from other disciplines catering to different patient populations often provide CPD for family doctors. The Working Party on Education of the World Organisation of Family Doctors (WONCA) sought to develop global standards in CPD for family doctors. The standards were developed through an iterative process with reference to published best practices for effective CPD. Adapted for family doctors from the World Federation for Medical Education's CPD for Medical Doctors: WFME Global Standards for Quality Improvement', the WONCA CPD Standards for Family Doctors were approved by WONCA Council in November 2016. The objectives of the standards are to: (1) Provide a resource for family doctors and/or groups of family doctors to design and structure a program of CPD to reinforce lifelong learning; (2) Optimise current CPD systems such that, through more effective program design and delivery, family doctors are advancing in patient care and their discipline; (3) Offer a set of globally recognised standards developed through a family medicine perspective to provide feedback on existing CPD programs and systems and encourage international recognition of CPD activities. The WONCA Global CPD Standards should inspire best practices in family medicine CPD, assisting family doctors in providing excellent care.

    This study examined changes in leisure activities of older adults over an 8-year period, and associated sociodemographic and health characteristics. Data were from a longitudinal study conducted in Winnipeg, Manitoba, Canada; 380 respondents were interviewed in-person in both 1985 and 1993. Changes in ten specific activities and the overall number of activities continued were examined. Theater/movies/spectator sports and travel were the activities least likely to be continued over the 8-year period; watching television and reading were most likely to be continued. Characteristics significantly related to changes in activities were age, gender, education, and self-rated health in 1985 as well as changes in marital status, self-rated health, and functional ability between 1985 and 1993, although no consistent pattern emerged. Leisure education is discussed as a means of introducing modifications to enhance older adults' participation in desired activities. Directions for future research are highlighted.

    2017-02-01

    Participating in continuing professional development (CPD) activities is a requirement for dental practitioners to keep their skills and knowledge up to date. Understanding the ways dental practitioners engage with professional development and the impact on practice is not fully known (Eaton et al. 2011, http://www.gdc-uk.org/Aboutus/policy/Documents/Impact%20Of%20CPD%20In%20Dentistry.pdf). The aim of this study was to gain insights into the ways that dentists reflect on their professional development and what may be influencing their choices. Empirical qualitative data were collected by semi-structured interviewing of five mid-career dentists. Using grounded theory, the data were analysed for themes about CPD choice and participation. Three themes were identified as influences to dentists' choices of CPD with pragmatic considerations of how new learning could benefit their patients and their practices. Dental practitioners were influenced by the requirements of external regulatory bodies which they did not consider to necessarily improve practice. Dentists working in primary care in the UK are undertaking CPD which is influenced by the pragmatic requirements of running a small business and to meet regulatory requirements.

    Penn, John M.

    2013-01-01

    This paper describes the adoption of a Test Driven Development approach and a Continuous Integration System in the development of the Trick Simulation Toolkit, a generic simulation development environment for creating high fidelity training and engineering simulations at the NASA/Johnson Space Center and many other NASA facilities. It describes what was learned and the significant benefits seen, such as fast, thorough, and clear test feedback every time code is checked-in to the code repository. It also describes a system that encourages development of code that is much more flexible, maintainable, and reliable. The Trick Simulation Toolkit development environment provides a common architecture for user-defined simulations. Trick builds executable simulations using user-supplied simulation-definition files (S_define) and user supplied "model code". For each Trick-based simulation, Trick automatically provides job scheduling, checkpoint / restore, data-recording, interactive variable manipulation (variable server), and an input-processor. Also included are tools for plotting recorded data and various other supporting tools and libraries. Trick is written in C/C++ and Java and supports both Linux and MacOSX. Prior to adopting this new development approach, Trick testing consisted primarily of running a few large simulations, with the hope that their complexity and scale would exercise most of Trick's code and expose any recently introduced bugs. Unsurprising, this approach yielded inconsistent results. It was obvious that a more systematic, thorough approach was required. After seeing examples of some Java-based projects that used the JUnit test framework, similar test frameworks for C and C++ were sought. Several were found, all clearly inspired by JUnit. Googletest, a freely available Open source testing framework, was selected as the most appropriate and capable. The new approach was implemented while rewriting the Trick memory management component, to eliminate a

    Full Text Available Purpose: The paper aims to study the relationship of Line Managers’ (LMs Human Resource (HR role and its facets within employee’s Continuous Professional Development (CPD.Design/methodology/approach: A quantitative approach using 100 questionnaires were distributed to line managers in a South East Asia with a response rate of 87%.Findings: Results depict that LMs are actively involved in Strategic Partner, Employee Champion, and Change Agent roles. Study also shows that these three HR roles correlate with employee CPD. LMs’ are neither involved in Administrative Expert role, nor it correlates with employee Continuous Professional Development.Research limitations: Inability of the line managers to be fully involved with the four HR roles constraints the process of line manager deployment of HR roles specifically to employee CPD.Practical implications: Argues that the importance of strategic partner, employee champion, and change agent roles are the most important barrier and enabler of employee CPD, thus indirectly promoting organizational success and productivity.Social implications: Highlights the difficulties of managing organisations by getting the line managers directly involve in the development of employee CPD. Many line managers have to be made and given opportunities to develop their capabilities on this platform. Contends that HR can help an organization to succeed, provided that all line managers understand their roles, work together and take responsibility for their contribution. In addition is the adoption of the HR roles for the smooth delivery of HR functions which aligns with the overall organizational success.Originality/value: Specific HR roles are significant importance to the development of employee CPD within the setting of this South East Asian organization.

  12. Development of a process for continuous determination of aluminium in bauxite

    Freitas, A.M.R. de.

    1984-01-01

    A system for aluminium analysis in bauxite using activation technique with the aid of a 5 Ci 241 Am/Be neutron source was developed. The system comprises the following steps: sampling, irradiation and counting. The reaction 27 Al(n,γ) 28 Al is used for determination of aluminium. A 2'' x 2'' NaI(T1) scintillation detector was used for the γ-activity measurements and integral counting technique was employed. Half-life determinations for samples were carried out in order to assure that the induced activity was predominantly due to the radionuclide 28 Al. In order to construct a system with solids, paraffin was chosen as moderator and reflector and an optimum irradiation position was determined. Analysis on a laboratory scale with 100g of the sample showed a good linear correlation between counts and aluminium content in bauxite samples. An irradiation chamber consisting of neutron source, moderator and reflector was constructed for activation of 2 Kg samples. Analysis with these bauxite samples indicated a relative precision in the range of 2 to 3% in less than ten minutes. Based on these results, a preliminary pilot-project was designed for continuous aluminium analysis in bauxite. (Author) [pt

    Continuing professional development (CPD) is an obligation for all Australasian geriatricians; however, there are no systematic data regarding Australian and New Zealand geriatricians' satisfaction with, and preferences for, CPD. To inform understanding of Australasian geriatricians' satisfaction with, and preferences for, CPD. An electronic survey to collect data relating to demographics, current CPD activities, preferred CPD activities and perceived major barriers to CPD was distributed to 706 geriatricians in Australia and New Zealand. Two hundred and thirteen (30%) responses were received. Respondents commonly reported CPD through participation in conferences (n = 205 (96%)) and research/educational activity (n = 146 (70%)). Most respondents agreed that the annual scientific meeting (n = 168 (79%)) and state-based meetings (n = 135 (63%)) are valuable for their CPD. Respondents perceived their professional (n = 155 (73%)) and non-professional (n = 21 (57%)) commitments as the major barriers to quality CPD. Respondents supported additional electronic CPD resources being made available, improved integration of assessment in CPD activities and flexible methods of CPD participation to meet the diverse needs of geriatricians. Respondents perceived the face-to-face CPD opportunities currently available to them as valuable for their CPD but seek additional, flexible products to enable CPD participation based on individual needs and preferences. © 2016 Royal Australasian College of Physicians.

    Continuing professional development is an important component of capacity building in low resource countries. The purpose of this case study is to describe the use of a contextual instructional framework to guide the processes and instructional design choices for a series of continuing professional development courses for physiotherapists in Rwanda. Four phases of the project are described: (1) program proposal, needs assessment and planning, (2) organization of the program and instructional design, (3) instructional delivery and (4) evaluation. Contextual facilitating factors and needs informed choices in each phase. The model resulted in delivery of continuing professional development to the majority of physiotherapists in Rwanda (n = 168, 0.48 rural/0.52 urban) with participants reporting improvement in skills and perceived benefit for their patients. Environmental and healthcare system factors resulted in offering the courses in rural and urban areas. Content was developed and delivered in partnership with Rwandan coinstructors. Based on the domestic needs identified in early courses, the program included advocacy and leadership activities, in addition to practical and clinical instruction. The contextual factors (environment, healthcare service organization, need for rehabilitation and status and history of the physiotherapy profession) were essential for project and instructional choices. Facilitating factors included the established professional degree and association, continuing professional development requirements, a core group of active professionals and an existing foundation from other projects. The processes and contextual considerations may be useful in countries with established professional-level education but without established postentry-level training. Implications for Rehabilitation Organizations planning continuing professional development programs may benefit from considering the context surrounding training when planning, designing and

    The effects of different doses of acute and continuous gamma-irradiation on the synthetic activity of rat blood lymphocytes stained with acridine orange were studied by fluorescent microspectrometry. Male rats were exposed to acute gamma-irradiation with doses of 7.5, 4 and 3 Gy, or to continuous irradiation with dose rates of 14.4, 2.1, 1.1 and 0.43 cGy/day, respectively. The changes of the synthetic activity of blood lymphocytes occurred in three main stages after acute gamma-irradiation and in four stages under continuous irradiation. The stages reflect the processes of depression and activation of the immune system under irradiation. Essential differences between the acute and continuous effects were observed in the first stage. After acute gamma-irradiation, the synthetic activity decreased sharply, indicating the predominant contribution of the damaging effect of irradiation, whereas under continuous irradiation, as a result of the stimulatory effect of low-dose irradiation, the synthetic activity increased during the first stage.

    2018-01-01

    Mining is considered the oldest conscious man activity. In the beginning, man searched for hard rocks in the outskirts area and used it to make weapons and ornaments. Subsequently, civilizations evolved through the development of infrastructure, buildings and monuments and finally, weapons. For all these it was necessary to have mineral raw materials obtained under increasingly difficult conditions, through increasingly evolved techniques. In this way, the art of mining and metallurgy was born, which led to the formation of scientific bases. The mining activity was equally art and science. The art and the science have been learned and taught in schools since ancient times and continue today in large universities with mining engineering, metallurgy, mining topography, mining environmental protection, and geology. Lately, in Romania, the mining high school has reached a deadlock and the middle and professional school has collapsed. The development of infrastructure, construction, etc. requires the exploitation and valorisation of mineral resources based on specialists. The paper warns against the danger of losing tradition and skills in mining engineers formation and militate for the re-establishment of professional and technical schools.

    Full Text Available The partners and allies of business practice in the processes of modernization of the economy are scientific-research institutions, such as scientific institutes, research-development units and universities. A market on which companies can look for the solutions they need and scientific-research institutions can look for inspiration, partners and capital is being formed. The market provides conditions for operation, development and implementation of developed solutions. Taking into consideration the complexity of market, technical, legal, financial, or intellectual property protection issues, research-development units are more and more frequently unable to function efficiently without a clear and unequivocal definition of goals, methods and conditions of activity. Their market offer has to take into consideration not just scientific-research, or methodological aspects. Taking into consideration continuously growing demands of the clients and pressure of the competition, scientific-research institutions have to pay attention also to market, information, personnel, or financial aspects typical of strictly commercial ventures. What may support a comprehensive preparation and implementation of scientific-research activities under market conditions are tools successfully used in trade and economy, such as business models. These issues are the basis of deliberations contained in this work.

    Directory of Open Access Journals (Sweden)

    Avdakovic Samir

    2014-08-01

    Full Text Available Analysis of power consumption presents a very important issue for power distribution system operators. Some power system processes such as planning, demand forecasting, development, etc.., require a complete understanding of behaviour of power consumption for observed area, which requires appropriate techniques for analysis of available data. In this paper, two different time-frequency techniques are applied for analysis of hourly values of active and reactive power consumption from one real power distribution transformer substation in urban part of Sarajevo city. Using the continuous wavelet transform (CWT with wavelet power spectrum and global wavelet spectrum some properties of analysed time series are determined. Then, empirical mode decomposition (EMD and Hilbert-Huang Transform (HHT are applied for the analyses of the same time series and the results showed that both applied approaches can provide very useful information about the behaviour of power consumption for observed time interval and different period (frequency bands. Also it can be noticed that the results obtained by global wavelet spectrum and marginal Hilbert spectrum are very similar, thus confirming that both approaches could be used for identification of main properties of active and reactive power consumption time series.

  6. Neural speech recognition: continuous phoneme decoding using spatiotemporal representations of human cortical activity

    Moses, David A.; Mesgarani, Nima; Leonard, Matthew K.; Chang, Edward F.

    2016-10-01

    Objective. The superior temporal gyrus (STG) and neighboring brain regions play a key role in human language processing. Previous studies have attempted to reconstruct speech information from brain activity in the STG, but few of them incorporate the probabilistic framework and engineering methodology used in modern speech recognition systems. In this work, we describe the initial efforts toward the design of a neural speech recognition (NSR) system that performs continuous phoneme recognition on English stimuli with arbitrary vocabulary sizes using the high gamma band power of local field potentials in the STG and neighboring cortical areas obtained via electrocorticography. Approach. The system implements a Viterbi decoder that incorporates phoneme likelihood estimates from a linear discriminant analysis model and transition probabilities from an n-gram phonemic language model. Grid searches were used in an attempt to determine optimal parameterizations of the feature vectors and Viterbi decoder. Main results. The performance of the system was significantly improved by using spatiotemporal representations of the neural activity (as opposed to purely spatial representations) and by including language modeling and Viterbi decoding in the NSR system. Significance. These results emphasize the importance of modeling the temporal dynamics of neural responses when analyzing their variations with respect to varying stimuli and demonstrate that speech recognition techniques can be successfully leveraged when decoding speech from neural signals. Guided by the results detailed in this work, further development of the NSR system could have applications in the fields of automatic speech recognition and neural prosthetics.

    2015-01-01

    This paper summarizes the recent development of an adaptive aeroelastic wing shaping control technology called variable camber continuous trailing edge flap (VCCTEF). As wing flexibility increases, aeroelastic interactions with aerodynamic forces and moments become an increasingly important consideration in aircraft design and aerodynamic performance. Furthermore, aeroelastic interactions with flight dynamics can result in issues with vehicle stability and control. The initial VCCTEF concept was developed in 2010 by NASA under a NASA Innovation Fund study entitled "Elastically Shaped Future Air Vehicle Concept," which showed that highly flexible wing aerodynamic surfaces can be elastically shaped in-flight by active control of wing twist and bending deflection in order to optimize the spanwise lift distribution for drag reduction. A collaboration between NASA and Boeing Research & Technology was subsequently funded by NASA from 2012 to 2014 to further develop the VCCTEF concept. This paper summarizes some of the key research areas conducted by NASA during the collaboration with Boeing Research and Technology. These research areas include VCCTEF design concepts, aerodynamic analysis of VCCTEF camber shapes, aerodynamic optimization of lift distribution for drag minimization, wind tunnel test results for cruise and high-lift configurations, flutter analysis and suppression control of flexible wing aircraft, and multi-objective flight control for adaptive aeroelastic wing shaping control.

    The paper discusses exponential stability of distributed delayed and impulsive cellular neural networks with partially Lipschitz continuous activation functions. By relative nonlinear measure method, some novel criteria are obtained for the uniqueness and exponential stability of the equilibrium point. Our method abandons usual assumptions on global Lipschitz continuity, boundedness and monotonicity of activation functions. Our results are generalization and improvement of some existing ones. Finally, two examples and their simulations are presented to illustrate the correctness of our analysis. Copyright © 2012 Elsevier Ltd. All rights reserved.

    We have constructed the system to monitor the artificial beta aerosol activity around the nuclear power plants continuously in real time. The smaller releases of artificial radionuclides from the nuclear power plants can be lost in the fluctuations of the natural background of the beta aerosol activity, when only the beta activity of the aerosol is measured. This method to discriminate the artificial and the natural beta activity of the aerosol is based on the fact that the ratio of the natural alpha and beta activities of the aerosol is almost constant. The detection limit of this system is below 3 Bq/m 3 . (author)

    2015-12-01

    Full Text Available In the modern conditions the socio-economic paradigm is changing, on the one hand, due to the transition to knowledge economy and, on the other hand, due to the need to develop innovation that determine competitiveness and the development level of national economies in the world. It is obvious that the progressive upgrade and the improvement of production processes (change in technological modes can not be implemented without the increase in the level of human capital in the society and the enhancement of potential and qualification of the workforce. These changes largely depend on the education system. In almost all world countries there is an active process of modernization and change in the system of training. New forms and approaches appear, for example lifelong education (concept “Lifelong education”, informal forms of learning, self-education, etc. Without the development of these approaches it is not possible to become a competitive state in changing social, political and economic environment. This is particularly true for countries, which experience changes in the technological mode and have the necessity to transfer to new technologies. Russia is among such countries nowadays. In our opinion, the modern reforms do not give the opportunity to fulfill the main task of education – to ensure and create conditions for self-determination and self-moralization of an individual in the society, achieve the desired level of knowledge for development of innovation in the regions. In the framework of the conducted research we get the classification of all Russian regions by indicators, such as “innovation” and “investment attractiveness”, with the levels of education being taken into account. This approach, on the one hand, shows the heterogeneity of socio-economic development of the country’s regions and, on the other hands, ‒ allows us to reveal the fact that the same federal district can include both regions-locomotives and

  14. Steady state, erosional continuity, and the topography of landscapes developed in layered rocks

    Perne, Matija; Covington, Matthew D.; Thaler, Evan A.; Myre, Joseph M.

    2017-01-01

    The concept of topographic steady state has substantially informed our understanding of the relationships between landscapes, tectonics, climate, and lithology. In topographic steady state, erosion rates are equal everywhere, and steepness adjusts to enable equal erosion rates in rocks of different strengths. This conceptual model makes an implicit assumption of vertical contacts between different rock types. Here we hypothesize that landscapes in layered rocks will be driven toward a state of erosional continuity, where retreat rates on either side of a contact are equal in a direction parallel to the contact rather than in the vertical direction. For vertical contacts, erosional continuity is the same as topographic steady state, whereas for horizontal contacts it is equivalent to equal rates of horizontal retreat on either side of a rock contact. Using analytical solutions and numerical simulations, we show that erosional continuity predicts the form of flux steady-state landscapes that develop in simulations with horizontally layered rocks. For stream power erosion, the nature of continuity steady state depends on the exponent, n, in the erosion model. For n = 1, the landscape cannot maintain continuity. For cases where n ≠ 1, continuity is maintained, and steepness is a function of erodibility that is predicted by the theory. The landscape in continuity steady state can be quite different from that predicted by topographic steady state. For n stream power erosion model, continuity steady state provides a general mathematical tool that may also be useful to understand landscapes that develop by other erosion processes.

    2012-05-01

    To review published studies evaluating the impact of continuing professional development (CPD) programmes on rural nurses palliative care capabilities in order to inform the development of targeted learning activities for this population. An integrative review. Searches of key electronic databases and the World Wide Web was undertaken using key words, followed by hand searching for relevant articles. All studies were reviewed by two authors using a critical appraisal tool and level of evidence hierarchy. The search strategies generated 74 articles, with 10 studies meeting the inclusion criteria. All of these studies evaluated palliative care CPD programmes involving rural nurses which focused on increasing palliative care capabilities. The evidence generated by this review was limited by the absence of randomised controlled trials. A level III-1 study, with a small sample size provided the highest level of evidence, but the lack of control negated the investigators' capacity to confirm causality. Few studies measured the impact of CPD on the quality of care or utilised novel technology to address the tyranny of distance. Despite, these limitations valuable insights into the barriers and facilitators to engaging rural nurses in palliative care learning opportunities were identified. Evidence that CPD impacts positively on patient and families outcomes is necessary to sustain an on-going investment in learning activities. In order to optimise the opportunities afforded by emerging web-based technology rural nurses' need to develop and maintain their computer competencies. Further investigation of the impact of specialist clinical placements on rural nurses' palliative care capabilities is also indicated. Copyright © 2011 Elsevier Ltd. All rights reserved.

    2017-07-01

    All health and social care professionals learn on the job through both formal and informal learning processes, which contributes to continuous professional development (CPD). This study explored workplace learning in General Practices, specifically looking at the role of informal learning and the workplace practices that appear to support or restrict that learning, as well as how technology was integrated into these learning processes. Three focus groups with general practitioners, practice nurses, managerial and administrative staff were conducted followed by twelve individual semi-structured interviews with participants drawn from the focus groups. Three observations of multi-disciplinary team meetings were used to establish potential team-based learning activities. Triggers for informal workplace learning included patients presenting challenging or unusual conditions; exposure to others' professional practice; and policy driven changes through revised guidance and protocols. By exploring how these triggers were acted upon, we identified mechanisms through which the primary care workplace supports or restricts informal learning through working practices, existing technologies and inter-professional structures. Informal workplace learning was identified as arising from both opportunistic encounters and more planned activities, which are both supported and restricted through a variety of mechanisms. Maximising informal learning opportunities and removing barriers to doing so should be a priority for primary care practitioners, managers and educators.

    Heavy metals play an important role within the spectrum of the various pollutants, emitted into the environment via human activities. In contrast to most organic pollutants, heavy metal can not be degraded. Many soils, lakes and rivers show a high contamination with heavy metals due to the enrichment of these pollutants. In addition to existing chemical-physical and biological technologies for the treatment of heavy metal containing waste waters a demand for new, efficient and low-cost cleaning technologies exists, particularly for high volumes of weakly contaminated waters. Such a technology was developed within the framework of a scientific project of the European Union. The approach makes use of a continuously operated, moving-bed Astrasand filter, which has been operated as a continuous biofilm reactor. By inoculation of the reactor with bacteria providing different, defined mechanisms of metal immobilization, and by continuous supply of suitable nutrients, a metal-immobilizing biofilm is built up and regenerated continuously. Metal-enriched biomass is removed continuously from the system, and the contained metals can be recycled by pyrometallurgical treatment of the biomass. The subjects of the present work were the optimization of the nutrient supply for the process of metal removal, the investigation of the toxicity of different waste waters, the optimization of inoculation and biofilm formation, set-up and operation of a lab scale sand filter and the operation of a pilot scale sand filter treating rinsing water of a chemical nickel plating plant. First, basic parameters like toxicity of heavy metal-containing waste waters and the influence of the nutrition of bacteria on biosorption and total metal removal were examined, using freely suspended bacteria in batch culture. Concerning toxicity great differences could be found within the spectrum of heavy metal-containing waste waters tested. Some waters completely inhibited growth, while others did not

    Nguyen, Nhan T. (Inventor)

    2016-01-01

    An aerodynamic control apparatus for an air vehicle improves various aerodynamic performance metrics by employing multiple spanwise flap segments that jointly form a continuous or a piecewise continuous trailing edge to minimize drag induced by lift or vortices. At least one of the multiple spanwise flap segments includes a variable camber flap subsystem having multiple chordwise flap segments that may be independently actuated. Some embodiments also employ a continuous leading edge slat system that includes multiple spanwise slat segments, each of which has one or more chordwise slat segment. A method and an apparatus for implementing active control of a wing shape are also described and include the determination of desired lift distribution to determine the improved aerodynamic deflection of the wings. Flap deflections are determined and control signals are generated to actively control the wing shape to approximate the desired deflection.

    2004-02-01

    Continuity of care can be a challenge for cardiac patients, many of whom require chronic and complex management from a variety of health care personnel in multiple settings. For health services research, measures are needed that encompass the multifaceted nature of continuity of care for cardiac patients. To assess continuity of care from the patient's perspective, a comprehensive self-report instrument of continuity of care for patients with congestive heart failure and atrial fibrillation was developed and validated. Based on published work, patient interviews and provider input, the Heart Continuity of Care Questionnaire (HCCQ) was developed to assess various aspects of care in the transition from hospital to home. The HCCQ covered a variety of content areas relevant to cardiac care. The HCCQ and either the Continuity of Care Index (CCI) or the Minnesota Living with Heart Failure Questionnaire (MLHFQ) were completed by 83 patients who had been discharged for at least six months. Most items had good response rates. The subscales, defined a priori, had good reliability (subscales alpha ranged from 0.80 to 0.93). The HCCQ and its subscales had strong correlations with the CCI but not the MLHFQ. The HCCQ subscales demonstrated better known group validity than the CCI. In this preliminary study, the HCCQ appears to be a comprehensive, reliable and valid measure of continuity of care from the patient perspective. Further studies of the validity, generalizability and use are needed.

    2017-09-01

    The aim of the study was to complete a collaborative review of Radiography continuing professional development (CPD) research material to support the production of European Federation of Radiographer Societies (EFRS) CPD recommendations. A meta-ethnography approach to literature review was applied focussing upon commonalities rather than discrepancies between research outcomes. This facilitated exploration of context across the geographical region of Europe with national variations in CPD governance. The seven phases of the meta-ethnographic approach were followed by two independent experienced researchers. A third researcher mediated the findings which were then explored collaboratively with the EFRS CPD working group for concordance. Phase seven of the meta-ethnography involved interpreting an expression of the synthesis from the previous stages. Six main corroborating themes emerged in this process and following mediation were expressed as themes; knowledge, skills & competency, needs/gap analysis, multi-layered/multi-modal, barriers and drivers; regulation vs autonomy; fostering collaboration - harnessing technology. The primary feature of CPD activity should be the resulting impact - to patients, the service, the profession and the individual; with all stakeholders working in partnership. CPD activity must be flexible/multi-modal to support the changing growth/dynamic workforce. All stakeholders should utilise communication and technology resources and make efforts to improve collaboration between the management, regulators and educators to support Radiographers to develop meaningful CPD. Health services across Europe are under increasing stress and a principal factor going forwards will be managing increasing demands on healthcare staff whilst supporting enhancement of the knowledge, skills and competency base.

    We analyze continuous seismic records from 18 permanent stations operated in vicinity of the Klyuchevskoy group of volcanos (Kamchatka, Russia) during the period between 2009 and 2014. We explore the stability of the inter-station cross-correlation to detect different periods of sustained emission from seismic energy. The main idea of this approach is that cross-correlation waveforms computed from a wavefield emitted by a seismic source from a fixed position remain stable during the period when this source is acting. The detected periods of seismic emission correspond to different episodes of activity of volcanoes: Klyuchevskoy, Tolbachik, Shiveluch, and Kizimen. For Klyuchevskoy and Tolbachik whose recent eruptions are mostly effusive, the detected seismic signals correspond to typical volcanic tremor, likely caused by degassing processes. For Shiveluch and Kizimen producing more silicic lavas, the observed seismic emission often consists of many repetitive long period (LP) seismic events that might be related to the extrusion of viscous magmas. We develop an approach for automatic detection of these individual LP events in order to characterize variations of their size and recurrence in time.

  9. 2D CFD Analysis of an Airfoil with Active Continuous Trailing Edge Flap

    Jaksich, Dylan; Shen, Jinwei

    2014-11-01

    Efficient and quieter helicopter rotors can be achieved through on-blade control devices, such as active Continuous Trailing-Edge Flaps driven by embedded piezoelectric material. This project aims to develop a CFD simulation tool to predict the aerodynamic characteristics of an airfoil with CTEF using open source code: OpenFOAM. Airfoil meshes used by OpenFOAM are obtained with MATLAB scripts. Once created it is possible to rotate the airfoil to various angles of attack. When the airfoil is properly set up various OpenFOAM properties, such as kinematic viscosity and flow velocity, are altered to achieve the desired testing conditions. Upon completion of a simulation, the program gives the lift, drag, and moment coefficients as well as the pressure and velocity around the airfoil. The simulation is then repeated across multiple angles of attack to give full lift and drag curves. The results are then compared to previous test data and other CFD predictions. This research will lead to further work involving quasi-steady 2D simulations incorporating NASTRAN to model aeroelastic deformation and eventually to 3D aeroelastic simulations.

    Manifestations of internalizing problems, such as specific symptoms of anxiety and depression, can change across development, even if individuals show strong continuity in rank-order levels of internalizing problems. This illustrates the concept of heterotypic continuity, and raises the question of whether common measures might be construct-valid for one age but not another. This study examines mean-level changes in internalizing problems across a long span of development at the same time as accounting for heterotypic continuity by using age-appropriate, changing measures. Internalizing problems from age 14-24 were studied longitudinally in a community sample (N = 585), using Achenbach's Youth Self-Report (YSR) and Young Adult Self-Report (YASR). Heterotypic continuity was evaluated with an item response theory (IRT) approach to vertical scaling, linking different measures over time to be on the same scale, as well as with a Thurstone scaling approach. With vertical scaling, internalizing problems peaked in mid-to-late adolescence and showed a group-level decrease from adolescence to early adulthood, a change that would not have been seen with the approach of using only age-common items. Individuals' trajectories were sometimes different than would have been seen with the common-items approach. Findings support the importance of considering heterotypic continuity when examining development and vertical scaling to account for heterotypic continuity with changing measures.

  11. Bora and Aurora-A continue to activate Plk1 in mitosis.

    Polo-like kinase-1 (Plk1) is required for proper cell division. Activation of Plk1 requires phosphorylation on a conserved threonine in the T-loop of the kinase domain (T210). Plk1 is first phosphorylated on T210 in G2 phase by the kinase Aurora-A, in concert with its cofactor Bora. However, Bora was shown to be degraded prior to entry into mitosis, and it is currently unclear how Plk1 activity is sustained in mitosis. Here we show that the Bora-Aurora-A complex remains the major activator of Plk1 in mitosis. We show that a small amount of Aurora-A activity is sufficient to phosphorylate and activate Plk1 in mitosis. In addition, a fraction of Bora is retained in mitosis, which is essential for continued Aurora-A-dependent T210 phosphorylation of Plk1. We find that once Plk1 is activated, minimal amounts of the Bora-Aurora-A complex are sufficient to sustain Plk1 activity. Thus, the activation of Plk1 by Aurora-A may function as a bistable switch; highly sensitive to inhibition of Aurora-A in its initial activation, but refractory to fluctuations in Aurora-A activity once Plk1 is fully activated. This provides a cell with robust Plk1 activity once it has committed to mitosis.

    2018-01-01

    Full Text Available ABSTRACT Objective: To reflect on Continuing Education in Health as an organizational strategy for the development of nurses' competences. Methods: A theoretical-reflective study was performed, combining concepts from Continuing Education in Health, organizational strategy and professional competence, understood as key elements for the work of nurses in health services. Results: To understand how to live together, individuals need to have knowledge about others, their history and traditions. When "learning how to do", they acquire broader competence to deal with unexpected situations and to facilitate team work. With regard to "learning how to be", they are encouraged to acquire autonomy and discernment on behalf of the group. If the focus is on development rather than control, there is shared interest and an integrated and strategic model for nurses' competences to be improved. Conclusion: The development of competences in nurses is the basis for the Learning Paths as a possible operationalization of Continuing Education in Health.

    2001-10-01

    This study evaluated the magnitude and location of activity of diabetic patients at high risk for foot amputation. Twenty subjects aged 64.6 +/- 1.8 years with diabetes, neuropathy, deformity, or a history of lower-extremity ulceration or partial foot amputation were dispensed a continuous activity monitor and a log book to record time periods spent in and out of their homes for 1 week. The results indicate that patients took more steps per hour outside their home, but took more steps per day inside their homes. Although 85% of the patients wore their physician-approved shoes most or all of the time while they were outside their homes, only 15% continued to wear them at home. Focusing on protection of the foot during in-home ambulation may be an important factor on which to focus future multidisciplinary efforts to reduce the incidence of ulceration and amputation. The ability to continuously monitor the magnitude, duration, and time of activity ultimately may assist clinicians in dosing activity just as they dose drugs.

    Graphical abstract: Display Omitted Highlights: ► Effects of air calcination and steam activation on TiO 2 fibers were studied. ► The photocatalytic activity was evaluated by degradation of formaldehyde. ► Steam activation promoted the anatase–rutile phase transformation. ► Steam activation decreased grain size and increased special surface area. ► Steam activation improved photocatalytic activity of TiO 2 fibers. -- Abstract: Effects of air calcination and steam activation, on phase transformation, microstructure and photocatalytic activity of continuous TiO 2 fibers prepared by sol–gel method were studied. The fibers were characterized by XRD, SEM, and N 2 adsorption–desorption. The photocatalytic activity was evaluated by photocatalytic degradation of formaldehyde. Results showed that 100% rutile fibers heat-treated in air and steam were obtained at 800 °C and 600 °C, respectively. The anatase grain sizes and special surface areas of the fibers heat-treated at 500 °C in air and steam were 31.6 nm, 22.7 nm, 26.7 m 2 /g and 32.3 m 2 /g, respectively. The degradation rates of formaldehyde over the fibers heat-treated at 500 °C in air and steam were 92.3% and 98.6% after 14 h under UV irradiation, respectively. Compared with the air calcination, the steam activation promoted the anatase–rutile phase transformation, reduced the grain size, increased the special surface area, and improved photocatalytic activity of continuous TiO 2 fibers.

    2017-12-01

    A personal learning project (PLP) is an accredited form of Continuing Professional Development (CPD) in Canada, and is a self-initiated learning activity that is stimulated by a question, issue or dilemma in one's professional practice. Many complex cases or issues have no answers that are readily available. Many physicians rely day to day on other physician colleagues that they may consult in their institution. Given the paucity of same specialty Physical Medicine and Rehabilitation colleagues in Canadian centres, the idea of Virtual Spinal Cord Injury (SCI) Hallway germinated, to provide a simple tool to extend our hallways to reach colleagues with similar interests across the country. The Virtual SCI Hallway is a service set up on Yahoo Groups, with no cost to the users. On this invite-only site, members may post a question, and then all members receive the post by email. Any member may respond. The SCI Hallway has been running successfully for over 13 years. As of January 2017, there were 38 members, with 2124 messages within approximately 324 conversations. Activity has been consistent since 2003. Questions and posts are not always medical expert related; there are also advocacy, professional, and scholar-role related posts. Communication amongst specialists about practice and management of complicated problems is important for CPD, yet is difficult in subspecialized areas of medicine. Although there are many chat-pages in different areas of medicine on the internet, to our knowledge, there is not another secure, invite-only site that is low-maintenance and no cost.

    Zino, Lorenzo; Rizzo, Alessandro; Porfiri, Maurizio

    2016-11-01

    Activity-driven networks are a powerful paradigm to study epidemic spreading over time-varying networks. Despite significant advances, most of the current understanding relies on discrete-time computer simulations, in which each node is assigned an activity potential from a continuous distribution. Here, we establish a continuous-time discrete-distribution framework toward an analytical treatment of the epidemic spreading, from its onset to the endemic equilibrium. In the thermodynamic limit, we derive a nonlinear dynamical system to accurately model the epidemic spreading and leverage techniques from the fields of differential inclusions and adaptive estimation to inform short- and long-term predictions. We demonstrate our framework through the analysis of two real-world case studies, exemplifying different physical phenomena and time scales.

    2018-01-01

    Within South Africa, few public service departments understand the concepts of business continuity management (BCM) and what it takes to implement a well-constructed business continuity plan. Likewise, few of these entities understand the purpose of designing and maintaining resilient systems that are immune to incidents. This paper discusses the integration of the South African Disaster Management Act 2002, the Disaster Management Framework and the National Development Plan, linking these to BCM, through a resilience period model, as a means for the implementation of resilience strategies. The goals of the National Development Plan are outlined with a view to how resilience can be achieved in each. A resilience period model has been advocated for the implementation of projects within the public sector in order to provide continuity and sustainability.

    Three methods for calculating continuous-energy eigenvalue sensitivity coefficients were developed and implemented into the SHIFT Monte Carlo code within the Scale code package. The methods were used for several simple test problems and were evaluated in terms of speed, accuracy, efficiency, and memory requirements. A promising new method for calculating eigenvalue sensitivity coefficients, known as the CLUTCH method, was developed and produced accurate sensitivity coefficients with figures of merit that were several orders of magnitude larger than those from existing methods.

  4. Continued Advancement of Supported Liquid Membranes for Carbon Dioxide Control in Extravehicular Activity Applications

    2015-01-01

    The Development of a new, robust, portable life support system (PLSS) is currently a high NASA priority in order to support longer and safer extravehicular activity (EVA) missions that will be necessary as space travel extends to near-Earth asteroids and eventually Mars. One of the critical PLSS functions is maintaining the carbon dioxide (CO2) concentration in the suit at acceptable levels. The Metal Oxide (MetOx) canister has a finite CO2 adsorption capacity and therefore in order to extend mission times, the unit would have to be larger and heavier, which is undesirable; therefore new CO2 control technologies must be developed. While recent work has centered on the use of alternating sorbent beds that can be regenerated during the EVA, this strategy increases the system complexity and power consumption. A simpler approach is to use a membrane that vents CO2 to space but retains oxygen(O2). A membrane has many advantages over current technology: it is a continuous system with no theoretical capacity limit, it requires no consumables, and it requires no hardware for switching beds between absorption and regeneration. Conventional gas separation membranes do not have adequate selectivity for use in the PLSS, but the required performance could be obtained with a supported liquid membrane (SLM), which consists of a microporous film filled with a liquid that selectively reacts with CO2 over oxygen (O2). In a recently completed Phase II Small Business Innovative Research project, Reaction Systems developed a new reactive liquid that has effectively zero vapor pressure, making it an ideal candidate for use in an SLM. Results obtained with the SLM in a flat sheet configuration with representative pressures of CO2, O2, and water (H2O) have shown that the CO2 permeation rate and CO2/O2 selectivity requirements have been met. In addition, the SLM vents moisture to space very effectively. The SLM has also been prepared and tested in a hollow fiber form, which will be

    This study was done to develop a measurement tool for evaluation of continuing nursing education programs and to verify its validity for effective management and quality of education programs. The draft of the evaluation measurement was developed from consultation with professionals, focus group interviews targeting groups of nurses, and individual interviews with education program planners. After 6 professionals examined content validity, 46 items were retained. A pilot-survey was conducted to confirm the time required to complete the questionnaire and the level of understanding of general content and each item in the questionnaire. Construct validity was verified through exploratory factor analysis of data from a survey with 44 items completed by 452 nurses and 59 education program planners. The final evaluation measurement for continuing nursing education programs consisted of 6 evaluation factors and 36 evaluation items. The 6 evaluation factors included identifying program goals and target groups, program planning, performance, operation and management, program outcomes, and program effectiveness. The evaluation measurement for continuing nursing education programs developed in this study is considered suitable to utilize as an evaluation measurement of the quality of continuing education programs for nurses.

    This study was conducted to explore the changes in soil microbial populations, enzyme activity, and tuber yield under the rotation sequences of Potato–Common vetch (P–C), Potato–Black medic (P–B) and Potato–Longdong alfalfa (P–L) in a semi–arid area of China. The study also determined the effects of continuous potato cropping (without legumes) on the above mentioned soil properties and yield. The number of bacteria increased significantly (p continuous cropping soils, respectively compared to P–C rotation. The highest fungi/bacteria ratio was found in P–C (0.218), followed by P–L (0.184) and then P–B (0.137) rotation over the different cropping years. In the continuous potato cropping soils, the greatest fungi/bacteria ratio was recorded in the 4–year (0.4067) and 7–year (0.4238) cropping soils and these were significantly higher than 1–year (0.3041), 2–year (0.2545) and 3–year (0.3030) cropping soils. Generally, actinomycetes numbers followed the trend P–L>P–C>P–B. The P–L rotation increased aerobic azotobacters in 2–year (by 26% and 18%) and 4–year (40% and 21%) continuous cropping soils compared to P–C and P–B rotation, respectively. Generally, the highest urease and alkaline phosphate activity, respectively, were observed in P–C (55.77 mg g–1) and (27.71 mg g–1), followed by P–B (50.72 mg mg–1) and (25.64 mg g–1) and then P–L (41.61 mg g–1) and (23.26 mg g–1) rotation. Soil urease, alkaline phosphatase and hydrogen peroxidase activities decreased with increasing years of continuous potato cropping. On average, the P–B rotation significantly increased (p improve soil biology environment, alleviate continuous cropping obstacle and increase potato tuber yield in semi–arid region. PMID:28463981

    To clarify the geothermal activity in the geothermal fields in New Zealand, gravity monitoring was conducted using SCINTREX automatic gravimeter. The measurements were conducted between the end of January and the beginning of March, 1996. Firstly, continuous monitoring was conducted at the standard point for about ten days, and the tidal components were estimated from the records. After that, continuous monitoring was conducted at Waimangu area for several days. Continuous monitoring was repeated at the standard point, again. At the Waimangu area, three times of changes in the pulse-shape amplitude of 0.01 mgal having a width of several hours were observed. For the SCINTREX gravimeter, the inclination of gravimeter is also recorded in addition to the change of gravity. During the monitoring, the gravimeter was also inclined with the changes of gravity. This inclination was useful not only for the correction of gravity measured, but also for evaluating the ground fluctuation due to the underground pressure source. It is likely that the continuous gravity monitoring is the relatively conventional technique which is effective for prospecting the change of geothermal reservoir. 2 figs.

    2015-01-01

    Finnish Assistive Technology Device Service centers raised the question about education to the full-time workers of ATD Services. They nominated a group which included representatives of universities, ATD Service centers and national authorities. This small group drew up background questionnaires concerning the education, its content and length. Three universities started the education, the aim of which was to learn new methods to develop their own work, learning by doing at work with their superiors. This continuous professional education corresponded to 30 ECTS credits and lasted 10 months. Based on the feedback from the guiding group of CPE, students and their superiors, this type of education is needed. It met its goals by giving students methods to develop their work and broaden their view on ATD service when having discussions with other experts. Continuous professional education needs to be developed further and it could also be part of joined European education with national elements.

    2007-12-01

    Two sampling strategies were studied to develop an automatic instrument for the continuous measurement of atmospheric carbonyl compounds. Because of its specificity towards carbonyls compounds, sampling by using a transfer of gaseous phase in a liquid phase associated with a simultaneous chemical derivatization of the trapped compounds was first studied. However, this method do not allow a quantitative sampling of all studied carbonyl compounds, nor a continuous measurement in the field. To overcome the difficulties, a second strategy was investigated: the cryogenic adsorption onto solid adsorbent followed by thermodesorption and a direct analysis by GC/MS. Collection efficiency using different solid adsorbents was found greater than 95% for carbonyl compounds consisting of 1 to 7 carbons. This work is a successful first step towards the realization of the automatic sampling device for a continuous measurement of atmospheric carbonyls compounds. (author)

    Under the auspices of the Integrated High Performance Turbine Engine Technology Initiative, the Naval Air Warfare Center conducts advanced development programs for demonstration in the next generation of air-breathing propulsion systems. Among the target technologies are gas path and lube oil seals. Two development efforts currently being managed by NAWCAD are the High Performance Compressor Discharge Film-Riding Face Seal and the Subsonic Core High Speed Air/Oil Seal. The High Performance Compressor Discharge Film-Riding Face Seal Program aims at reducing parasitic leakage through application of a film-riding face sea concept to the compressor discharge location of a Phase 2 IHPTET engine. An order-of-magnitude leakage reduction relative to current labyrinth seal configurations is expected. Performance goals for these seals are (1) 1200 F air temperature, (2) 800 feet-per-second surface velocity, and (3) 600 SPI differential pressure. The two designs chosen for fabrication and rig test are a spiral groove and a Rayleigh step seal. Rig testing is currently underway. The Subsonic Core High Speed Air/Oil Seal Program is developing shaft-to-ground seals for next-generation propulsion systems that will minimize leakage and provide full life. Significantly higher rotor speeds and temperatures will be experienced. Technologies being exploited include, hydrodynamic lift assist features, ultra light weight designs, and improved cooling schemes. Parametric testing has been completed; a final seal design is entering the endurance test phase.

    Full Text Available he corporations gain a power of influence, unthinkable years ago; they have acquired more and more rights and, in some way, govern the life of billions of peoples and of the earth in general. With every right, comes though the responsibility of the conservation and development of the environment in which the corporations act. The banking system has a major role to play in the evolution of the international framework, given its position on the economic stage. Some important banking groups realized this fact and made important steps in the area. The case study of the Holland banking group ABN AMRO proves the complexity of the introduction of sustainable development in the core of the financial business. The implementation is neither easy nor cheap. It implies essential changes in the bank management, in the way to determine the financial policies, in how to choose the clients, the employees, the suppliers etc. Led in an efficient way, sustainable banking implies innovation, creativity and, implicitly, new gains, through creating new products and opening new markets. The international banking community proved, through leading examples (ABN AMRO Bank, HSBC Group, Rabobank Group, JP Morgan Chase, Citigroup etc. that it understands the importance, the necessity and also the viability of the sustainable development.

  15. Development of a continuous energy version of KENO V.a

    1997-01-01

    KENO V.a is a multigroup Monte Carlo code that solves the Boltzmann transport equation and is used extensively in the nuclear criticality safety community to calculate the effective multiplication factor k eff of systems containing fissile material. Because of the smaller amount of disk storage and CPU time required in calculations, multigroup approaches have been preferred over continuous energy (point) approaches in the past to solve the transport equation. With the advent of high-performance computers, storage and CPU limitations are less restrictive, thereby making continuous energy methods viable for transport calculations. Moreover, continuous energy methods avoid many of the assumptions and approximations inherent in multigroup methods. Because a continuous energy version of KENO V.a does not exist, the objective of the work is to develop a new version of KENO V.a that utilizes continuous energy cross sections. Currently, a point cross-section library, which is based on a raw continuous energy cross-section library such as ENDF/B-V is not available for implementation in KENO V.a; however, point cross-section libraries are available for MCNP, another widely used Monte Carlo transport code. Since MCNP cross sections are based on ENDF data and are readily available, a new version of KENO V.a named PKENO V.a has been developed that performs the random walk using MCNP cross sections. To utilize point cross sections, extensive modifications have been made to KENO V.a. At this point in the research, testing of the code is underway. In particular, PKENO V.a, KENO V.a, and MCNP have been used to model nine critical experiments and one subcritical problem. The results obtained with PKENO V.a are in excellent agreement with MCNP, KENO V.a, and experiments

    2013-11-01

    A novel integrated immobilized enzyme-reactor system involving a continuous stirred tank reactor with two packed bed reactors in series was developed for the continuous production of biodiesel. The problem of methanol solubility into oil was solved by introducing a stirred tank reactor to dissolve methanol into partially converted oil. This step made the process perfectly continuous without requiring any organic solvent and intermittent methanol addition in the process. The substrate feeding rate of 0.74 mL/min and enzyme loading of 0.75 g per reactor were determined to be optimum for maximum biodiesel yield. The integrated continuous process was stable up to 45 cycles with biodiesel productivity of 137.2 g/L/h, which was approximately 5 times higher than solvent free batch process. In comparison with the processes reported in literature using expensive Novozyme 435 and hazardous organic solvent, the present process is completely green and perfectly continuous with economic and environmental advantages.

    The Secretary of Energy is required by law to explore, prospect, conserve, develop, use, and operate the Naval Petroleum and Oil Shale Reserves. The Naval Petroleum Reserves Production Act of 1976 (Public Law 94-258), requires that the Naval Petroleum Reserves be produced at their maximum efficient rate (MER), consistent with sound engineering practices, for a period of six years. To fulfill this mission, DOE is proposing continued development activities which would include the drilling of approximately 250 oil production and injection (gas, water, and steam) wells, the construction of between 25 and 30 miles of associated gas, water, and steam pipelines, the installation of several production and support facilities, and the construction of between 15 and 20 miles of access roads. These drilling and construction estimates include any necessary activities related to the operation of the Rocky Mountain Oilfield Testing Center (RMOTC). The purpose of RMOTC will be to provide facilities and necessary support to government and private industry for testing and evaluating new oilfield and environmental technologies, and to transfer these results to the petroleum industry through seminars and publications. Continued development activities either have no potential to result in adverse environmental impacts or would only result in adverse impacts that could be readily mitigated. The small amounts of disturbed surface area will be reclaimed to its original natural state when production operations terminate. The preparation of an environmental impact statement is not required, and the DOE is issuing this Finding of No Significant Impact (FONSI). 73 refs.

    The objective of this research was to find out the continuity of seuramoe keu, tungai/rambat, and seuramoe likeut (three fundamental spaces in rumoh Aceh) in three development stages of houses since 1980 until present time. The development starts from the stilt house (santeut), non-stilt house, up to the contemporary house. In the period in which modern life has an impact in changing people lifestyles and then affects the mindset of the need for spaces, the study of the continuity of the three spaces mentioned reflects how far the culture of the people of Aceh in the past persist today, considering architecture, including spaces, is the reflection of the socio-cultural of inhabitants/community. The study was conducted by observing the spaces on seven sample houses and by interviewing the house owners to find out the factors that affect the existence/non-existence of spaces. The results showed that the three spaces (seuramoe keu, tungai, and seuramoe likeut) undergone the continuity despite the differences occurred in the interior compared to rumoh Aceh, meanwhile the continuity factor was based on the culture of life that is still firmly held by Acehnese.

    Journal clubs are an essential tool in promoting clinical evidence-based medical education to all medical and allied health professionals. Twitter represents a public, microblogging forum that can facilitate traditional journal club requirements, while also reaching a global audience, and participation for discussion with study authors and colleagues. The aim of the current study was to evaluate the current state of social media-facilitated journal clubs, specifically Twitter, as an example of continuing professional development. A systematic review of literature databases (Medline, Embase, CINAHL, Web of Science, ERIC via ProQuest) was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A systematic search of Twitter, the followers of identified journal clubs, and Symplur was also performed. Demographic and monthly tweet data were extracted from Twitter and Symplur. All manuscripts related to Twitter-based journal clubs were included. Statistical analyses were performed in MS Excel and STATA. From a total of 469 citations, 11 manuscripts were included and referred to five Twitter-based journal clubs (#ALiEMJC, #BlueJC, #ebnjc, #urojc, #meded). A Twitter-based journal club search yielded 34 potential hashtags/accounts, of which 24 were included in the final analysis. The median duration of activity was 11.75 (interquartile range [IQR] 19.9, SD 10.9) months, with 7 now inactive. The median number of followers and participants was 374 (IQR 574) and 157 (IQR 272), respectively. An overall increasing establishment of active Twitter-based journal clubs was observed, resulting in an exponential increase in total cumulative tweets (R(2)=.98), and tweets per month (R(2)=.72). Cumulative tweets for specific journal clubs increased linearly, with @ADC_JC, @EBNursingBMJ, @igsjc, @iurojc, and @NephJC, and showing greatest rate of change, as well as total impressions per month since establishment.

    The need to strengthen the preparation of individuals leading and providing continuing professional development (CPD) programs has grown dramatically within the current health care context. CPD is an integral part of the continuum of health professions education and cuts across the multiple disciplines and professions delivering health care. Each health care profession needs not only to keep up to date on new information within their specific discipline but also continue to develop and expand skills in areas that link interdisciplinary areas, such as quality of care delivery and communication skills, across various professions. In this article, we examine the changing context in which CPD is provided and explain how graduate programs in health professions education can be used as a strategy to strengthen the preparation of individuals for CPD practice and advance the delivery of CPD through evidence-based and innovative strategies.

    The system is to ensure a continuous irradiation of several specimens, especially for activation analysis. The specimens rotate in a hollow body which is axially movable along a rail. The rotation is effected by a turbine driven by hydraulic or pneumatic power and placed in the hollow body which can be used for example in the rabbit system of a nuclear reactor. The driving medium serves both as conveying medium for the system and drive for the rotating drum and as coolant for the specimens and results in radiation protection. The geometric arrangement and design of both the turbine and the whole system is decribed in detail. (UWI) [de

  13. Measuring the development of inhibitory control: The challenge of heterotypic continuity.

    Science.gov (United States)

    Petersen, Isaac T; Hoyniak, Caroline P; McQuillan, Maureen E; Bates, John E; Staples, Angela D

    2016-06-01

    Inhibitory control is thought to demonstrate heterotypic continuity, in other words, continuity in its purpose or function but changes in its behavioral manifestation over time. This creates major methodological challenges for studying the development of inhibitory control in childhood including construct validity, developmental appropriateness and sensitivity of measures, and longitudinal factorial invariance. We meta-analyzed 198 studies using measures of inhibitory control, a key aspect of self-regulation, to estimate age ranges of usefulness for each measure. The inhibitory control measures showed limited age ranges of usefulness owing to ceiling/floor effects. Tasks were useful, on average, for a developmental span of less than 3 years. This suggests that measuring inhibitory control over longer spans of development may require use of different measures at different time points, seeking to measure heterotypic continuity. We suggest ways to study the development of inhibitory control, with overlapping measurement in a structural equation modeling framework and tests of longitudinal factorial or measurement invariance. However, as valuable as this would be for the area, we also point out that establishing longitudinal factorial invariance is neither sufficient nor necessary for examining developmental change. Any study of developmental change should be guided by theory and construct validity, aiming toward a better empirical and theoretical approach to the selection and combination of measures.

    Streamlining the manufacturing process has been recognized as a key issue to reduce production costs and improve safety in pharmaceutical manufacturing. Although data available from earlier developmental stages are often sparse and unstructured, they can be very useful to improve the understanding about the process under development. In this paper, a general procedure is proposed for the application of latent variable statistical methods to support the development of new continuous processes in the presence of limited experimental data. The proposed procedure is tested on an industrial case study concerning the development of a continuous line for the manufacturing of paracetamol tablets. The main driving forces acting on the process are identified and ranked according to their importance in explaining the variability in the available data. This improves the understanding about the process by elucidating how different active pharmaceutical ingredient pretreatments, different formulation modes and different settings on the processing units affect the overall operation as well as the properties of the intermediate and final products. The results can be used as a starting point to perform a comprehensive and science-based quality risk assessment that help to define a robust control strategy, possibly enhanced with the integration of a design space for the continuous process at a later stage.

  15. Management of continual improvement for facilities and activities: A structured approach

    International Nuclear Information System (INIS)

    2006-04-01

    In recent years there has been an upward trend in the safety and operational performance of nuclear installations. Safe, efficient operation is their goal. Continual improvement of the processes of organizations has led to enhanced safety performance and efficiency benefits such as cost reductions and improved cycle times. Many organizations have experienced significant cost improvement largely by or through better financial management and a common drive to reduce costs brought on by commercial pressures. Without the use of a structured methodology to identify and implement improvements, changes to an organization to reduce costs through cutting staff and activities could eventually fail to produce the desired changes and even have a negative effect on safety and overall performance. The following fundamental principles are considered essential to the effective introduction of structured continual improvement: - Long term commitment from senior management throughout the entire organization; - The implementation in the organization of a process management approach such as that advocated by IAEA Safety Standards, ISO 9001, Malcolm Baldridge National Quality Award and European Foundation for Quality Management Business Excellence model; - The alignment of the processes with the objectives of the organization through the organization's business plan; - The utilization by Management of the process information as an input to managing the organization; - The employment of the information derived from the process performance to identify and prioritize the processes that require improvement; - The active participation of all staff of the organization to using its processes in order to contribute to continual process improvement (CPI). This publication defines a structured approach for continual improvement and focuses on the way an organization can improve its processes. It is recognized that there are many different approaches and methods available in the marketplace to

  16. Absolute exponential stability of recurrent neural networks with Lipschitz-continuous activation functions and time delays.

    2004-04-01

    This paper investigates the absolute exponential stability of a general class of delayed neural networks, which require the activation functions to be partially Lipschitz continuous and monotone nondecreasing only, but not necessarily differentiable or bounded. Three new sufficient conditions are derived to ascertain whether or not the equilibrium points of the delayed neural networks with additively diagonally stable interconnection matrices are absolutely exponentially stable by using delay Halanay-type inequality and Lyapunov function. The stability criteria are also suitable for delayed optimization neural networks and delayed cellular neural networks whose activation functions are often nondifferentiable or unbounded. The results herein answer a question: if a neural network without any delay is absolutely exponentially stable, then under what additional conditions, the neural networks with delay is also absolutely exponentially stable.

    General Atomics is developing manufacturing methods for vanadium alloys as part of a program to encourage the development of low activation alloys for fusion use. The culmination of the program is the fabrication and installation of a vanadium alloy structure in the DIII-D tokamak as part of the Radiative Divertor modification. Water-cooled vanadium alloy components will comprise a portion of the new upper divertor structure. The first step, procuring the material for this program has been completed. The largest heat of vanadium alloy made to date, 1200 kg of V-4Cr-4Ti, has been produced and is being converted into various product forms. Results of many tests on the material during the manufacturing process are reported. Research into potential fabrication methods has been and continues to be performed along with the assessment of manufacturing processes particularly in the area of joining. Joining of vanadium alloys has been identified as the most critical fabrication issue for their use in the Radiative Divertor Program. Joining processes under evaluation include resistance seam, electrodischarge (stud), friction and electron beam welding. Results of welding tests are reported. Metallography and mechanical tests are used to evaluate the weld samples. The need for a protective atmosphere during different welding processes is also being determined. General Atomics has also designed, manufactured, and will be testing a helium-cooled, high heat flux component to assess the use of helium cooled vanadium alloy components for advanced tokamak systems. The component is made from vanadium alloy tubing, machined to enhance the heat transfer characteristics, and joined to end flanges to allow connection to the helium supply. Results are reported

    Full Text Available Research conducted by the British Council concerning modern continuous professional development of teachers has been analyzed. The issue concerning foreign language teachers’ professional development has been considered. Productive approach to this process that gives a teacher the opportunities to define aspects of their professional activities that are in need of improvement and introduce appropriate strategies of their own professional development has been characterized. Direct connection between continuous teachers’ professional development and the level of students’ academic achievements has been stressed. Key characteristics of effective professional development have been defined, namely: being correspondent to actual needs of teachers and students; teachers’ involvement into the decision making concerning the content and the fulfillment of professional development; provision of cooperation and teachers’ experience exchange; collegiality presupposing common work of teachers and educational establishments in general; practicality, that is the fulfillment of professional development directly in the process of teachers’ work in class; obligatory character of professional development as indispensable part of teachers’ work; constant reflection and research; prioritizing academic achievements of students as the main stimulus for professional learning of teachers; continuity of professional development and its consideration not as separate forms of work. Modern widely used forms of teacher professional development have been analyzed, namely: self-education, common lessons planning with their further analysis; professional discussions concerning new teaching techniques and the appropriateness of their application; reflexive groups for teaching experience exchange and lessons analysis (video recording of lessons or students’ works, observation/attending teachers’ lessons with their further discussion in constructive form and

  5. Product sampling during transient continuous countercurrent hydrolysis of canola oil and development of a kinetic model

    KAUST Repository

    Wang, Weicheng

    2013-11-01

    A chemical kinetic model has been developed for the transient stage of the continuous countercurrent hydrolysis of triglycerides to free fatty acids and glycerol. Departure functions and group contribution methods were applied to determine the equilibrium constants of the four reversible reactions in the kinetic model. Continuous countercurrent hydrolysis of canola oil in subcritical water was conducted experimentally in a lab-scale reactor over a range of temperatures and the concentrations of all neutral components were quantified. Several of the rate constants in the model were obtained by modeling this experimental data, with the remaining determined from calculated equilibrium constants. Some reactions not included in the present, or previous, hydrolysis modeling efforts were identified from glycerolysis kinetic studies and may explain the slight discrepancy between model and experiment. The rate constants determined in this paper indicate that diglycerides in the feedstock accelerate the transition from "emulsive hydrolysis" to "rapid hydrolysis". © 2013 Elsevier Ltd.

  7. Design of a continuous passive and active motion device for hand rehabilitation.

    Science.gov (United States)

    Birch, B; Haslam, E; Heerah, I; Dechev, N; Park, E J

    2008-01-01

    This paper presents the design of a novel, portable device for hand rehabilitation. The device provides for CPM (continuous passive motion) and CAM (continuous active motion) hand rehabilitation for patients recovering from damage such as flexor tendon repair and strokes. The device is capable of flexing/extending the MCP (metacarpophalangeal) and PIP (proximal interphalangeal) joints through a range of motion of 0 degrees to 90 degrees for both the joints independently. In this way, typical hand rehabilitation motions such as intrinsic plus, intrinsic minus, and a fist can be achieved without the need of any splints or attachments. The CPM mode is broken into two subgroups. The first mode is the use of preset waypoints for the device to cycle through. The second mode involves motion from a starting position to a final position, but senses the torque from the user during the cycle. Therefore the user can control the ROM by resisting when they are at the end of the desired motion. During the CPM modes the device utilizes a minimum jerk trajectory model under PD control, moving smoothly and accurately between preselected positions. CAM is the final mode where the device will actively resist the movement of the user. The user moves from a start to end position while the device produces a torque to resist the motion. This active resistance motion is a unique ability designed to mimic the benefits of a human therapist. Another unique feature of the device is its ability to independently act on both the MCP and PIP joints. The feedback sensing built into the device makes it capable of offering a wide and flexible range of rehabilitation programs for the hand.

  8. Governing mobile technology use for continuing professional development in the Australian nursing profession.

    Mather, Carey Ann; Gale, Fred; Cummings, Elizabeth Anne

    2017-01-01

    The rapid growth in the use of mobile technology in Australia has outpaced its governance, especially in healthcare settings. Whilst some Australian professional bodies and organisations have developed standards and guidelines to direct appropriate use of social media and mobile technology, clear governance arrangements regarding when, where and how to use mobile technology at point of care in nursing are currently lacking. This paper analyses how the use of mobile technology by nurses at point of care is governed. It highlights the existence of a mobile technology paradox: an identified inability of nurses to access mobile technology in a context where it is increasingly recognised that its use in situ can enhance nursing practice while contributing to mobile learning and continuing professional development. While the recent release of the Registered Nurse Standards for Practice and accompanying Standard for Continuing Professional Development provides some direction regarding professional standards to support the use of mobile technology for mobile learning, we argue a more inclusive approach is required if emerging technologies are to be fully embraced. We describe how an implementation framework, underpinned by more detailed standards, guidelines and codes, could enable the nursing profession to be leaders in embedding mobile technology in healthcare environments nationally and globally. The prevalence of mobile technology in Australia has outpaced its governance in healthcare environments. Its limited availability at point of care is hindering nursing practice, mobile learning and continuing professional development. We discuss the emergence of mobile technology and impediments for its use by nurses in situ. We analyse the professional codes governing nursing, outlining potential reforms to enable implementation of mobile technology at point of care by nurses.

    2016-01-01

    In this work we report the first attempt to study the effect of activity cliffs over the generalization ability of machine learning (ML) based QSAR classifiers, using as study case a previously reported diverse and noisy dataset focused on drug induced liver injury (DILI) and more than 40 ML classification algorithms. Here, the hypothesis of structure-activity relationship (SAR) continuity restoration by activity cliffs removal is tested as a potential solution to overcome such limitation. Previously, a parallelism was established between activity cliffs generators (ACGs) and instances that should be misclassified (ISMs), a related concept from the field of machine learning. Based on this concept we comparatively studied the classification performance of multiple machine learning classifiers as well as the consensus classifier derived from predictive classifiers obtained from training sets including or excluding ACGs. The influence of the removal of ACGs from the training set over the virtual screening performance was also studied for the respective consensus classifiers algorithms. In general terms, the removal of the ACGs from the training process slightly decreased the overall accuracy of the ML classifiers and multi-classifiers, improving their sensitivity (the weakest feature of ML classifiers trained with ACGs) but decreasing their specificity. Although these results do not support a positive effect of the removal of ACGs over the classification performance of ML classifiers, the "balancing effect" of ACG removal demonstrated to positively influence the virtual screening performance of multi-classifiers based on valid base ML classifiers. Specially, the early recognition ability was significantly favored after ACGs removal. The results presented and discussed in this work represent the first step towards the application of a remedial solution to the activity cliffs problem in QSAR studies.

    Morris, A. R.; Charlevoix, D. J.

    2014-12-01

    Developing confident, capable geoscientists from a diverse array of backgrounds requires, among many variables, the development of confident, capable mentors to help guide and support students along the path to professional positions. The geosciences are lagging behind other STEM fields in increasing the diversity of participants, and shifting the perspectives of those both inside and outside of the field requires intentional attention to ensuring undergraduate success. UNAVCO, Inc. is well-situated to both prepare undergraduate students for placement in geoscience technical positions and advanced graduate study and to provide mentoring resources for faculty engaged in supporting undergraduates from diverse backgrounds. UNAVCO is a university-governed consortium facilitating research and education in the geosciences. For the past 10 years, UNAVCO has managed Research Experiences in the Solid Earth Sciences for Students (RESESS), an NSF-funded multiyear geoscience research internship, community support, and professional development program. The primary goal of the RESESS program is to increase the number of historically underrepresented students entering the geosciences, whether continuing academic studies or moving into the workforce. Beginning in 2014, UNAVCO will add a second internship program to its portfolio. Leading Undergraduates in Challenges to Power Academic Development in the Geosciences (LAUNCHPAD) is aimed at involving two-year college students and lower-division undergraduates in projects that prepare them for independent research opportunities at UNAVCO and with other REU programs.

    Generally, carbon or graphite fibers (GFs) are used as the supporting materials for the preparation of flexible supercapacitors (SCs) by assembling various electrochemically active nanomaterials on them. A facile and rapid electrochemical oxidation method with a voltage of 3 V in a mixed H2SO4-HNO3 solution for 2-15 min is proposed to active continuous filament GFs. Detailed structural characterization, SEM, TEM, XRD, Raman and XPS demonstrate that the GFs-8 (oxidized for 8 min) possessing high specific surface area which provided numerous electrochemical sites and a large number of oxygen-containing functional groups producing pseudocapacitance. Cyclic voltammetric (CV), galvanostatic charge-discharge measurements and electrochemical impedance spectroscopy (EIS) are conducted to test the capacitive of GFs and activated GFs. The capacitance of GFs-8 reaches as high as 570 mF cm-1 at the current density of 1 mA cm-1 in LiCl electrolyte, a 1965-fold enhancement with respect to the pristine GFs (0.29 mF cm-1). The fabricated fiber solid-state supercapacitors (SSCs) provide high energy density of 0.68 mWh cm-3 at the power density 3.3 W cm-3 and have excellent durability with 90% capacitance retention after 10000 cycles. In addition, such fiber SSCs features flexibility and mechanical stability, which may have wide applications in wearable electronic devices.

    Recent studies have demonstrated that erythropoiesis-stimulating agents (ESAs) induce a tissue-protective effect in the kidney. In this study, we examined whether continuous erythropoietin receptor activator (CERA), a long-acting ESA, could prevent kidney injury, especially podocyte damage, in a rat model of nephrotic syndrome induced by puromycin aminonucleoside (PAN). Rats were injected with CERA (30 µg/kg) or vehicle 4 h before the injection of PAN (50 mg/kg). Renal function, kidney injury, and podocyte damage were assessed at 7 days. The levels of proteinuria, BUN, and plasma creatinine significantly increased in rats with PAN-induced nephrosis. Treatment with CERA significantly prevented these deteriorations induced by PAN. Glomerular lesions, especially vacuolation of podocytes, and the increase of desmin expression in PAN-treated rats were significantly ameliorated by treatment with CERA. Treatment with CERA also significantly prevented the decrease in the protein productions of nephrin and podocin in the kidneys of PAN-treated rats. We found persistent activation of the Akt signaling pathway in the kidneys of CERA-treated rats. CERA could ameliorate renal dysfunction in PAN-induced nephrosis, which might be due to the amelioration of podocyte injury. CERA inhibited the depletion of nephrin and podocin, key components of the glomerular filtration barrier, and alleviated proteinuria. Activation of the Akt signaling pathway might be involved in the renoprotective effect of CERA. Copyright © 2012 S. Karger AG, Basel.

    The authors investigated continuity and discontinuity of vocabulary skills in a population-based cohort in the Netherlands. Mothers of 3,759 children completed the Dutch version of the MacArthur Short Form Vocabulary Checklist (Zink & Lejaegere, 2003) at 18 months and a Dutch translation of the Language Development Survey (Rescorla, 1989) at 30 months. At both ages, expressive vocabulary delay was defined as vocabulary scores vocabulary development at both ages, 6.2% were "late bloomers," 6.0% had late onset expressive vocabulary delay, and 2.6% had persistent expressive vocabulary delay. Word production and comprehension at 18 months explained 11.5% of the variance in 30-month vocabulary scores, with low birth weight, child age, gender and ethnicity, maternal age and education, and parenting stress explaining an additional 6.2%. Multinomial logistic regression was used to identify biological, demographic, and psychological factors associated with each of the vocabulary delay outcome groups relative to the typically developing group. Although multiple perinatal, demographic, and maternal psychosocial factors significantly predicted vocabulary skills at 30 months, positive predictive value and sensitivity were low. Future studies should address to what extent additional factors, such as brain maturation and genetic influences, can improve the prediction and understanding of continuity and discontinuity of language delay.

  14. Preparing for New and Changing Roles in Research Libraries – the Need for Continuing Professional Development

    Full Text Available It is expected that library staff are qualified to offer high quality services to users visiting the physical library. Likewise, it is expected that they have substantial knowledge and skills needed for developing and maintaining electronic services and for dissemination of relevant services and facilities requested by the web-user. Serving remote library users calls for additional competencies, such as marketing, branding and communications skills in the electronic environment as well as knowledge of measuring and evaluation of the use of electronic services. It is a challenge to the staff to match particular needs and demands from different user groups, but also to library management staff to ensure that the competencies and skills are available in the organisation to match the needs of the user – wherever s/he might be located. Competencies are, in this context, defined as the combination of knowledge and experience that make the individual able to take the right actions in the daily working environment. What education and training needs emerge from the changing roles and new tasks? How might we identify the needs for continuing professional development? And how can we maintain and update skills and competencies acquired maybe 25 years ago? These are key questions – not only to be addressed to library managers, but also to be considered carefully by those institutions responsible for continuing education and professional development of library staff.

    To obtain feedback about the potential usefulness of a continuing professional development (CPD) portfolio for enhancing a faculty or practitioner's scholarship of teaching and learning (SoTL). A CPD portfolio approach to the SoTL was distributed in advance to registrants of the 2011 Annual AACP Teacher's Seminar. In an interactive workshop, faculty facilitators described a model for a CPD process applied to the development of an individual's SoTL. During the workshop, participants were asked to complete the initial sections of the portfolio to develop a personal plan for success in the SoTL. Post workshop, an evaluation form was distributed to the participants to obtain feedback about the CPD approach. Completed evaluation forms were collected, collated, and summarized. A total of 53 (14.1%) workshop participants completed the evaluation form of the 375 attendees. In all, 25 assistant professors, 14 associate professors, 4 full professors, 10 residents/students, 22 clinical, and 2 research faculty submitted evaluations. The proposed uses for the portfolio model selected most often by the responders were for personal development, faculty evaluation, increasing the SoTL, new faculty development, preceptor development, and residency training. A structured CPD portfolio model might be useful for the professional development of the SoTL.

    Full Text Available High quality neuroscience research requires accurate, reliable and well maintained neuroinformatics applications. As software projects become larger, offering more functionality and developing a denser web of interdependence between their component parts, we need more sophisticated methods to manage their complexity. If complexity is allowed to get out of hand, either the quality of the software or the speed of development suffer, and in many cases both. To address this issue, here we develop a scalable, low-cost and open source solution for continuous integration (CI, a technique which ensures the quality of changes to the code base during the development procedure, rather than relying on a pre-release integration phase. We demonstrate that a CI based workflow, due to rapid feedback about code integration problems and tracking of code health measures, enabled substantial increases in productivity for a major neuroinformatics project and additional benefits for three further projects. Beyond the scope of the current study, we identify multiple areas in which CI can be employed to further increase the quality of neuroinformatics projects by improving development practices and incorporating appropriate development tools. Finally, we discuss what measures can be taken to lower the barrier for developers of neuroinformatics applications to adopt this useful technique.

    Highlights: • ITER Continuous External Rogowskis are designed for plasma current measurement. • CER are located in the casing of Toroidal Field Coils and will operate at 4.5 K. • The design of the sensors has been completed and validated through prototypes. • Detailed assembly procedure inside the toroidal field coil casing has been defined. • The CER has passed all the ITER and F4E design review procedures. - Abstract: In ITER, an accurate measurement of plasma current, with high reliability, is mandatory as this parameter is used to demonstrate licensing compliance with regulatory limits. For that purpose, several independent measurements based on magnetic diagnostics have been proposed. Rogowski coils are standard inductive sensors for current measurement in many applications. In ITER, three continuous external Rogowski coils are to be installed in the casing of the toroidal field coils. These sensors are remarkable from several points of view: overall length is about 40 m, high sensitivity needed, located in the toroidal field coil casing at 4.5 K and complex 3D routing with tight bending radius of 50 mm. Since 2005 an extensive work has been carried out to develop and analyze several design options complying with ITER specifications. Prototypes of a selected continuous external Rogowski design were built and tested successfully in terms of electrical, thermal, mechanical and vacuum characteristics. Finally a detailed assembly procedure inside the toroidal field coil casing has been defined according to the coil manufacturing and assembly constraints.

  18. Application of active electrode compensation to perform continuous voltage-clamp recordings with sharp microelectrodes.

    Electrophysiological recordings of single neurons in brain tissues are very common in neuroscience. Glass microelectrodes filled with an electrolyte are used to impale the cell membrane in order to record the membrane potential or to inject current. Their high resistance induces a high voltage drop when passing current and it is essential to correct the voltage measurements. In particular, for voltage clamping, the traditional alternatives are two-electrode voltage-clamp technique or discontinuous single electrode voltage-clamp (dSEVC). Nevertheless, it is generally difficult to impale two electrodes in a same neuron and the switching frequency is limited to low frequencies in the case of dSEVC. We present a novel fully computer-implemented alternative to perform continuous voltage-clamp recordings with a single sharp-electrode. To reach such voltage-clamp recordings, we combine an active electrode compensation algorithm (AEC) with a digital controller (AECVC). We applied two types of control-systems: a linear controller (proportional plus integrative controller) and a model-based controller (optimal control). We compared the performance of the two methods to dSEVC using a dynamic model cell and experiments in brain slices. The AECVC method provides an entirely digital method to perform continuous recording and smooth switching between voltage-clamp, current clamp or dynamic-clamp configurations without introducing artifacts.

    Previously we examined the transfer, distribution and half-live of radiocaesium in broiler chicken after the application of artificially contaminated feed mixture or wheat wheat contaminated from the Chernobyl accident. Our results pointed to a different dynamics of radiocaesium in breast meat compared to leg meat in the chicken after short-time application (3 oral applications in 1 day). The aim of the present study was to find if the results are similar also after single and repeated (long-time) applications of an artificially contaminated feed mixture. Two experiments were carried out with broiler chickens (White Leghorn hybrid, race ISA VEDETTE). In experiment 1, one artificially contaminated oral dose of 5160 Bq of 137 Cs (activity concentration 1664 Bq/g) was administered to 18-day-old chickens. In experiment 2, artificially contaminated oral doses of 500 Bq of 137 Cs (activity concentration 161.3 Bq/g) were administered to 14-day-old chickens twice a day (at 8:00 and 20:00 h.) for 10 days. In either experiment, four chickens were slaughtered for activity determination in meat (breast and leg muscles) 6, 12, 24, 48 and 96 hours and 2, 4, 8, 10 days, respectively, after the first application of 137 Cs. The uptake of the single oral 137 Cs was rapid and the maximum 137 Cs activity concentrations were found in breast meat (0.783 Bq/g) 24 hours and in leg meat (1.005 Bq/g) 6 hours after 137 Cs application. From the 24th hour of the experiment, radiocaesium activity concentrations in breast and leg meat decreased with the biological half-life (T 1/2b ) of 84 and 66 hours, respectively. During a 10-day application of continuous doses of 137 Cs, the Cs activity concentrations increased and were 3.988 Bq/g in breast meat and 5.610 Bq/g in leg meat on day 2, and 7.427 Bq/g and 7.698 Bq/g, respectively, on day 10. Immediately after the administration of radiocaesium was stopped, the 137 Cs activity concentrations decreased rapidly with T 1/2b = 4.5 and 3.8 days in

    2018-01-01

    There is a proportion of the M. tuberculosis population that is refractory to the bactericidal action of antituberculosis antibiotics due to phenotypic tolerance. This tolerance can be impacted by environmental stimuli and the subsequent physiological state of the organism. It may be the result of preexisting populations of slow growing/non replicating bacteria that are protected from antibiotic action. It still remains unclear how the slow growth of M. tuberculosis contributes to antibiotic resistance and antibiotic tolerance. Here, we present a method for assessing the activity of antibiotics against M. tuberculosis using continuous culture, which is the only system that can be used to control bacterial growth rate and study the impact of slow or fast growth on the organism's response to antibiotic exposure.

    Full Text Available The performance of monolithic silica microreactors activated with sulphonic acid groups and a packed bed reactor with Amberlyst 15 resin were compared in the esterification of acetic acid with n-butanol. The monolithic microreactors were made of single silica rods with complex pore architecture, differing in the size of mesopores, and in particular, flow-through macropores which significantly affected the flow characteristic of the continuous system. The highest ester productivity of 105.2 mol·molH+−1·h−1 was achieved in microreactor M1 with the largest porosity, characterized by a total pore volume of 4 cm3·g−1, mesopores with 20 nm diameter, and large flow-through macropores 30–50 μm in size. The strong impact of the permeability of the monoliths on a reaction kinetics was shown.

    2008-01-01

    Previous research has suggested that the theory of planned behaviour is insufficient in capturing all the antecedents of physical activity participation and that continuation intentions or personality traits may improve the predictive validity of the model. The present study examined the combined effects of continuation intentions and personality traits on health behaviour within the theory of planned behaviour. To examine these effects, 180 university students (N = 180, Male = 87, Female = 93, Age = 19.14 years, SD = 0.94) completed self-report measures of the theory of planned behaviour, personality traits and continuation intentions. After 5 weeks, perceived achievement of behavioural outcomes and actual participation in physical activities were assessed. Results supported discriminant validity between continuation intentions, conscientiousness and extroversion and indicated that perceived achievement of behavioural outcomes and continuation intentions of failure predicted physical activity participation after controlling for personality effects, past behaviour and other variables in the theory of planned behaviour. In addition, results indicated that conscientiousness moderated the effects of continuation intentions of failure on physical activity such that continuation intentions of failure predicted physical activity participation among conscientious and not among less conscientious individuals. These findings suggest that the effects of continuation intentions on health behaviour are contingent on personality characteristics.

  4. Removing Copper from Contaminated Water Using Activated Carbon Sorbent by Continuous Flow

    Full Text Available Introduction: A major concern of human being is accumulation and toxicity of heavy metals in their body. Copper is a heavy metal ion that in concentration of 2 mg/l can cause numerous complications. Different treatment methods have been proposed for removing metals from contaminated water by researchers. Among these methods, sorption seems a better method with high removal efficiency. In this study, conditions for removal of copper ions by activated carbon sorbent were studied with continuous flow. Materials & Methods: This was a laboratory – experimental study. A 20mg/l solution of copper ions was prepared and passed through a 5 × 10 cm column with average output rate of 1.85 ml/min. Output of column was sampled every 30 minutes and the remaining amount of copper ion in each sample was measured by flame atomic absorption. Results: The empty bed volume (EBV was equal to 138 ml. The highest removal efficiency was 99.7 percent at 127 minutes. From equilibrium time, the removal efficiency was constant with time. The adsorption capacity of activated carbon was 0.25mg.g-1. The isotherm study indicated that the sorption data can be obeyed by both Langmuir and Freundlich isotherms (R2>0.95 but Langmuir model had higher agreement with this experimental data (R2= 0.988. Conclusion: The binding of ions to the sorbent in the adsorption process is extremely important. For this column 62.5 minutes after filling was appropriate, so the highest removal efficiency was obtained. Equilibrium time was dependent on the speed of influent through the column in the continuous flow. For selected column, the rate of 1.85 ml/min is a good performance.

  7. An integrated development workflow for community-driven FOSS-projects using continuous integration tools

    2016-04-01

    A complex software project in general with high standards regarding code quality requires automated tools to help developers in doing repetitive and tedious tasks such as compilation on different platforms and configurations, doing unit testing as well as end-to-end tests and generating distributable binaries and documentation. This is known as continuous integration (CI). A community-driven FOSS-project within the Earth Sciences benefits even more from CI as time and resources regarding software development are often limited. Therefore testing developed code on more than the developers PC is a task which is often neglected and where CI can be the solution. We developed an integrated workflow based on GitHub, Travis and Jenkins for the community project OpenGeoSys - a coupled multiphysics modeling and simulation package - allowing developers to concentrate on implementing new features in a tight feedback loop. Every interested developer/user can create a pull request containing source code modifications on the online collaboration platform GitHub. The modifications are checked (compilation, compiler warnings, memory leaks, undefined behaviors, unit tests, end-to-end tests, analyzing differences in simulation run results between changes etc.) from the CI system which automatically responds to the pull request or by email on success or failure with detailed reports eventually requesting to improve the modifications. Core team developers review the modifications and merge them into the main development line once they satisfy agreed standards. We aim for efficient data structures and algorithms, self-explaining code, comprehensive documentation and high test code coverage. This workflow keeps entry barriers to get involved into the project low and permits an agile development process concentrating on feature additions rather than software maintenance procedures.

  8. Current trends and status of continuing professional development in implant dentistry in Europe.

    2014-03-01

    Previous surveys have shown that newly graduated dentists, in most European countries, do not obtain adequate theoretical knowledge and, especially, clinical skills in implant dentistry (ID) through their undergraduate education and must therefore acquire knowledge and develop competencies through further postgraduate study. Moreover, clinicians, in general, need to continue to maintain the currency of their competence by undertaking ongoing continuing professional development (CPD). This seems particularly important in ID as techniques, and materials develop rapidly due to advances in biomedical technology. Despite recent developments, CPD in ID remains poorly organised with little standardisation or harmonisation across Europe. The objective of this survey was to explore the current status and trends within CPD education in ID in Europe. Stakeholders and opinion leaders associated with ID education were invited by email to fill an online questionnaire (closing date: 30th April 2013). Two hundred and forty-seven questionnaires were distributed, and two separate reminders were sent to participants in 38 European countries. The survey contained 14 multiple-choice questions, and the data were collected using SurveyMonkey© software, exported in SPSS (Inc, Chicago, IL, USA) format and analysed using descriptive statistics. Two hundred respondents working in 24 countries replied to the survey (response rate of 81% of invitees and 63% of countries surveyed). The results demonstrated a wide divergence in the content and structure of CPD in ID in Europe. Dentists need CPD to develop their skills and to maintain their competence in ID. There is an urgent need for structured and accredited CPD, which should be readily available to all dentists practising ID. It should have pre-determined learning objectives, delivered by accredited CPD providers and educators, and have assessable outcome measures to ensure the best possible impact on clinical practice and patient safety.

    Water quality in rivers results from biogeochemical processes in contributing hydrological compartments (soils, aquifers, hyporheic and riparian zones) and biochemical activity in the river network itself. Consequently, chemical fluxes fluctuate on multiple spatial and temporal scales, leading eventually to complex concentration signals in rivers. We characterized these fluctuations with innovative continuous monitoring of dissolved gases, to quantify transport and reaction processes occurring in different hydrological compartments. We performed stream-scale experiments in two headwater streams in Brittany, France. Factorial injections of inorganic nitrogen (NH4NO3), inorganic phosphate (P2O5) and multiple sources of labile carbon (acetate, tryptophan) were implemented in the two streams. We used a new field application of membrane inlet mass spectrometry to continuously monitor dissolved gases for multiple day-night periods (Chatton et al., 2016). Quantified gases included He, O2, N2, CO2, CH4, N2O, and 15N of dissolved N2 and N2O. We calibrated and assessed the methodology with well-established complementary techniques including gas chromatography and high-frequency water quality sensors. Wet chemistry and radon analysis complemented the study. The analyses provided several methodological and ecological insights and demonstrated that high frequency variations linked to background noise can be efficiently determined and filtered to derive effective fluxes. From a more fundamental point of view, the tested stream segments were fully characterized with extensive sampling of riverbeds and laboratory experiments, allowing scaling of point-level microbial and invertebrate diversity and activity on in-stream processing. This innovative technology allows fully-controlled in-situ experiments providing rich information with a high signal to noise ratio. We present the integrated nutrient demand and uptake and discuss limiting processes and elements at the reach and

    This article describes the process of developing and disseminating a Web-based library of geriatric clinical simulations used in continuing education workshops. Twenty-six peer-reviewed clinical simulations were developed on topics reflecting prevalent acute illnesses, conditions, or sentinel events that, if left undetected or untreated, could cause further comorbidity, hospitalization, or death. Geriatric nursing competencies identified by The John A. Hartford Foundation Institute for Geriatric Nursing were also incorporated. More than 700 workshop attendees and others have used these online clinical simulations. User evaluations of realism, accuracy of the situation or problem portrayed, and relevance to practice were rated as excellent or very good by more than 85% of the users. The University of North Carolina at Chapel Hill Center for Lifelong Learning Web site will offer this library with associated American Nurses Credentialing Center contact hours. This online access provides nurses high-quality continuing education offerings to increase knowledge and improve competence in the care of aging adults.

    This study used a data-driven, person-centered approach to examine the characterization, continuity, and etiology of child temperament from infancy to toddlerhood. Data from 561 families who participated in an ongoing prospective adoption study, the Early Growth and Development Study, were used to estimate latent profiles of temperament at 9, 18, and 27 months. Results indicated that four profiles of temperament best fit the data at all three points of assessment. The characterization of profiles was stable over time while membership in profiles changed across age. Facets of adoptive parent and birth mother personality were predictive of children’s profile membership at each age, providing preliminary evidence for specific environmental and genetic influences on patterns of temperament development from infancy to toddlerhood.

    Australian nurses and midwives are expected to compile a professional development portfolio during their annual registration process. This study aimed to ascertain the current understanding, practice and future continuing professional development (CPD) needs of nurses and midwives employed in a regional area of Queensland, Australia. Perceived barriers and incentives for CPD were also measured. 289 public and private hospital nurses and midwives responded to the survey. Results showed that participants understood the new requirements, valued ongoing learning, preferred education to occur within work hours, and considered their workplaces as accepting of change. Approximately two-thirds of participants believed CPD should be shared between them and their employers. Barriers to undertaking CPD included understaffing, and the concern that CPD would interfere with time outside work. Organisational support positively influenced attitudes to CPD. This study highlights the importance of supportive management in encouraging their workforce to embrace ongoing learning and change.

    The purpose of this DOE-funded effort is to develop continuous processes for solvent extraction of coal for the production of carbon products. The largest applications are those which support metals smelting, such as anodes for aluminum smelting and electrodes for arc furnaces. Other carbon products include materials used in creating fuels for the Direct Carbon Fuel Cell, metals smelting, especially in the aluminum and steel industries, as well as porous carbon structural material referred to as ''carbon foam'' and carbon fibers. During this reporting period, efforts have focused on the development of carbon electrodes for Direct Carbon Fuel Cells (DCFC), and on carbon foam composites used in ballistic armor, as well as the hydrotreatment of solvents used in the basic solvent extraction process. A major goal is the production of 1500 pounds of binder pitch, corresponding to about 3000 pounds of hydrotreated solvent.

    The Radiation Technology Center from Instituto de Pesquisas Energeticas e Nucleares (IPEN-CNEN/SP), Brazil, developed with a revolutionary design and national technology, a small size continuous run and multipurpose industrial gamma irradiator, to be used as a demonstration facility for manufacturers and contract service companies, which need economical and logistical in-house irradiation system alternatives. Also, to be useful for supporting the local scientific community on development of products and process using gamma radiation, assisting the traditional and potential users on process validation, training and qualification of operators and radioprotection officers. The developed technology for this facility consists of continuous tote box transport system, comprising a single concrete vault, where the automated transport system of products inside and outside of the irradiator utilizes a rotate door, integrated with the shielding, avoiding the traditional maze configuration. Covering 76 m 2 of floor area, the irradiator design is product overlap sources and the maximum capacity of cobalt-60 wet sources is 37 P Bq (1 MCi). The performed quantification program of this multipurpose irradiator was based on AAMI/ISO 11137 standard, which recommends the inclusion of the following elements: installation and process quantification. The initial load of the multipurpose irradiator was 3.4 P Bq (92.1 k Ci) with 13 cobalt-60 sources model C-188, supplied by MDS Nordion Ion Technologies - Canada. For irradiator dose optimization, the source distribution was done using the software Cadgamma developed by IPEN-CNEN/SP. The poly-methylmethacrylate (PMMA) dosimeters system, certified by the International Dose Assurance Service (IDAS) of the International Atomic Energy Agency (IAEA) was used for irradiator dose mapping. The economic analysis, performance concerning to dose uniformity and cobalt-60 utilization efficiency were calculated and compared with other commercial gamma

    Maternal and newborn mortality remains high in Liberia. There is a severe rural-urban gap in accessibility to health care services. A competent midwifery workforce is able to meet the needs of mothers and newborns. Evidence shows that competence can be assured through initial education along with continuous professional development (CPD). In the past, CPD was not regulated and coordinated in Liberia which is cpommon in the African region. To Support a competent regulated midwifery workforce through continuous professional development. A new CPD model was developed by the Liberian Board for Nursing and Midwifery. With its establishment, all midwives and nurses are required to undertake CPD programmes consisting of certified training and mentoring in order to renew their practicing license. The new model is being piloted in one county in which regular mentoring visits that include skills training are being conducted combined with the use of mobile learning applications addressing maternity health issues. Quality control of the CPD pilot is assured by the Liberian Board for Nursing and Midwifery. The mentoring visits are conducted on a clinical level but are coordinated on the national and county level. CPD using mobile learning on smartphones and regular mentoring visits not only improved knowledge and skills of midwives and nurses but also provided a solution to enhance accessibility in rural areas through improved communication and transportation, as well as improved career development of health personnel working in remote areas. Mentors were trained on a national, county, and health facility level in the pilot county with mentoring visits conducted regularly. The CPD programme of the Liberian Board for Nursing and Midwifery, currently in pilot-testing by various partners, aims to highlight the positive impact of the coordinating role of both the regulatory body and health authorities. Using regular process and programme reviews to improve capacity, knowledge, and

    Volumes of environmental data archives are growing immensely due to recent models, high performance computers and sensors development. It makes impossible their comprehensive analysis in conventional manner on workplace using in house computing facilities, data storage and processing software at hands. One of possible answers to this challenge is creation of virtual research environment (VRE), which should provide a researcher with an integrated access to huge data resources, tools and services across disciplines and user communities and enable researchers to process structured and qualitative data in virtual workspaces. VRE should integrate data, network and computing resources providing interdisciplinary climatic research community with opportunity to get profound understanding of ongoing and possible future climatic changes and their consequences. Presented are first steps and plans for development of VRE prototype element aimed at regional climatic and ecological monitoring and modeling as well as at continuous education and training support. Recently developed experimental software and hardware platform aimed at integrated analysis of heterogeneous georeferenced data "Climate" (http://climate.scert.ru/, Gordov et al., 2013; Shulgina et al., 2013; Okladnikov et al., 2013) is used as a VRE element prototype and approach test bench. VRE under development will integrate on the base of geoportal distributed thematic data storage, processing and analysis systems and set of models of complex climatic and environmental processes run on supercomputers. VRE specific tools are aimed at high resolution rendering on-going climatic processes occurring in Northern Eurasia and reliable and found prognoses of their dynamics for selected sets of future mankind activity scenaria. Currently the VRE element is accessible via developed geoportal at the same link (http://climate.scert.ru/) and integrates the WRF and «Planet Simulator» models, basic reanalysis and instrumental

    Exercise improves sleep quality, yet people with untreated obstructive sleep apnea (OSA) may engage in less physical activity (PA) due to fatigue and daytime sleepiness. We examined changes in PA and sleep quality before and after treatment with continuous positive airway pressure (CPAP) in OSA patients. In this prospective longitudinal study, persons with a primary diagnosis of OSA were enrolled at a community-based hospital in New York City. At 3 time intervals pre- and post-CPAP (3-8 months), we measured sleep quality using validated questionnaires, perceived PA using the International Physical Activity Questionnaire (IPAQ), and actual PA using pedometer steps per day. We sought to investigate how CPAP use and changes in sleep quality impacted the number of steps taken, as recorded in pedometer steps. In total, 62 patients were enrolled in the study from March 2012 to July 2014. In all, patients averaged 53 years of age, and 26 patients (42%) were female. Among all participants, 86% of persons had moderate to severe sleep apnea (AHI ≥15). Approximately 73% of participants were compliant with CPAP use. Poor sleep quality correlated with lower actual PA (P = .004) at baseline. At 3 and 7 months, there was significant improvement in sleep quality (Δ -2.63 ± 3.4 and Δ -3.5 ± 3.8; P improvement in sleep quality and actual PA.

  3. Overcoming Ex-Post Development Stagnation: Interventions with Continuity and Scaling in Mind

    Full Text Available Project interventions are important vehicles for development globally. However, while there is often allocation of resources for new and innovative (pilot projects—with varying levels of success—there is seemingly less focus on consolidating and/or scaling the positive impacts of successful larger interventions. Assuming an overarching development goal to have long lasting impact at scale, this approach seems somewhat contradictory. Scaling is often not integrated into project planning, design and implementation and rarely pursued genuinely in the ex-post. However, where demand for further development remains outstanding beyond project completion, opportunities may exist to build upon project platforms and extend benefits in a cost effective manner. This paper examines existing scaling typologies, before introducing “scaling-within” as a concept to promote greater continuity of development to a wider range of stakeholders. Scaling-within offers the opportunity to “in-fill” intervention principles and practices to both project and non-project communities within a broader strategic framework to address disparities and to promote sustainable development. The authors draw on research from case studies of large-scale integrated watershed rehabilitation projects and assess scaling-within against a contemporary scaling framework drawn from the literature. While the concept is tested with watersheds as the administrative unit, the authors anticipate applications for other project management units.

    Full Text Available The aim of this paper is to review issues in continuing professional development of vocational training to the mechanical industries. The spectacle of individuals entering the labour market without relevant qualifications is common in Malaysia. There are many who choose to work instead of pursuing further education after secondary school. In the labour market, these individuals are considered to be low-skilled workers because they had no training prior to employment. The role of employers in providing training and education to employees is vital in establishing career development of employees. Employers who contributed to their employees' training funds through Human Resources Development Council would provide opportunities to increase the skills of workers. Based on the Malaysia's Development Plan of Occupational Skill, the issues and challenges that have been identified in producing skilled workers in interpersonal and technical skills. This paper provided an opportunity to examine an enterprise-based approach to skill formation for workers with basic academic qualifications. It presents an alternative scenario to institution-based Technical and Vocational Education and Training (TVET, which many Malaysians are familiar with. A structured curriculum development of human resources learning needs according to the job profile of the typical individual and group work which will provide a clearer perspective on knowledge, competence and skill levels of employee behavior in performing tasks will be discussed. The biggest impact on this study is to produce high skill employees concerning customer satisfaction and increased organizational productivity towards high income nations.

    Full Text Available A facile and environmental friendly synthesis strategy based on pulsed laser ablation has been developed for potential mass production of Ag-loaded TiO2 (Ag/TiO2 nanoparticles. By sequentially irradiating titanium and silver target substrates, respectively, with the same 1064 nm 100 ns fiber laser, Ag/TiO2 particles can be fabricated. A postannealing process leads to the crystallization of TiO2 to anatase phase with high photocatalytic activity. The phase composition, microstructure, and surface state of the elaborated Ag/TiO2 are characterized by X-ray diffraction (XRD, energy dispersive X-ray (EDX, field emission scanning electron microscope (FESEM, transmission electron microscope (TEM, and X-ray photoelectron spectroscopy (XPS techniques. The results suggest that the presence of silver clusters deposited on the surface of TiO2 nanoparticles. The nanostructure is formed through laser interaction with materials. Photocatalytic activity evaluation shows that silver clusters could significantly enhance the photocatalytic activity of TiO2 in degradation of methylene blue (MB under UV light irradiation, which is attributed to the efficient electron traps by Ag clusters. Our developed Ag/TiO2 nanoparticles synthesized via a straightforward, continuous, and green pathway could have great potential applications in photocatalysis.

    2006-01-01

    There is a rich and long history of thermal infrared (TIR) remote sensing data for multidisciplinary Earth science research. The continuity of TIR data collection, however, is now in jeopardy given there are no planned future Earth observing TIR remote sensing satellite systems with moderately high spatial resolutions to replace those currently in orbit on NASA's Terra suite of sensors. This session will convene researchers who have actively worked in the field of TIR remote sensing to present results that elucidate the importance of thermal remote sensing to the wider Earth science research community. Additionally, this session will also exist as a forum for presenting concepts and ideas for new thermal sensing systems with high spatial resolutions for future Earth science satellite missions, as opposed to planned systems such as the Visible/Infrared Imager/Radiometer (VIIRS) suite of sensors on the National Polar-orbiting Operational Environmental Satellite System (NPOESS) that will collect TIR data at very coarse spatial resolutions.

    International Nuclear Information System (INIS)

    2013-01-01

    The report for long-term evaluation of active faults was published by the Headquarters for Earthquake Research Promotion on Nov. 2010. After occurrence of the 2011 Tohoku-oki earthquake, the safety review guide with regard to geology and ground of site was revised by the Nuclear Safety Commission on Mar. 2012 with scientific knowledges of the earthquake. The Nuclear Regulation Authority established on Sep. 2012 is newly planning the New Safety Design Standard related to Earthquakes and Tsunamis of Light Water Nuclear Power Reactor Facilities. With respect to those guides and standards, our investigations for developing the methods of evaluating active faults are as follows; (1) For better evaluation on activities of offshore fault, we proposed a work flow to date marine terrace (indicator for offshore fault activity) during the last 400,000 years. We also developed the analysis of fault-related fold for evaluating of blind fault. (2) To clarify the activities of active faults without superstratum, we carried out the color analysis of fault gouge and divided the activities into thousand of years and tens of thousands. (3) To reduce uncertainties of fault activities and frequency of earthquakes, we compiled the survey data and possible errors. (4) For improving seismic hazard analysis, we compiled the fault activities of the Yunotake and Itozawa faults, induced by the 2011 Tohoku-oki earthquake. (author)

    Online learning is frequently used in continuing professional development for qualified nurses and midwives. It is frequently assumed that the same package is appropriate for different groups of learners and that by reducing the need for tutorial input, tutorial time is saved. We evaluated the suitability of an online learning resource for suitability in continuing professional development for midwives. Originally developed for use as part of a work-based package for a specific audience, there had always been plans for more general use of the resource with other groups of health workers. Sequential mixed methods study. English universities. Seventy university tutors. Online questionnaire and in-depth interviews. Tutors did not consider that the online learning materials would be suitable for a wider audience without significant adaptation. They thought that uptake would increase need for tutorial input. Our findings demonstrate the pitfalls of removing learning from the context of practice. Technology customised to meet the needs of one group of learners probably does not have the potential for transfer to another group without significant adaptation. Those responsible for designing e-learning should take into account the needs of all the different audiences for whom the resource is intended from the outset, with consideration for the context in which learning will be applied to practice and how students will be supported. If the same package is to be used by different audiences and in different settings, tutors and students will require explicit instructions of how they should use the resource and depth of knowledge and level of competency that should be attained at the conclusion of the programme.

    2013-04-01

    Full Text Available Little is known about the efficacy of pulsed ultrasound compared with continuous ultrasound. Previous studies on the efficacy of pulsed ultrasound were not systematic and gave different results. In this study, the effects of pulse length, pulse interval, pulse length × pulse intervals, and treatment time on sonochemical activity were investigated using a simple oxidation of iodide method and a comparison of the efficacy of pulsed ultrasound and continuous ultrasound is made. The results showed that the main factor in the efficacy of pulsed ultrasound was pulse length when pulse length varied from 0.1 to 1 s. However, the main factors were pulse length, the pulse length × pulse interval, and pulse interval when pulse length varied from 1 to 9 s. Pulsed ultrasound had no effect when the pulse length was 0.1 s; however, the sonochemical activity of pulsed ultrasound decreased compared to continuous ultrasound as the pulse length varied from 0.1 to 1 s. The sonochemical activity of pulsed ultrasound either increased or decreased compared to continuous ultrasound when pulse length varied from 1 to 9 s, but the increase or decrease had no clear trend. The sonochemical activity was constant at Ton/Toff = 2 s/2 s and slightly decreased at Ton/Toff = 3 s/2 s with time, whereas the sonochemical activity of continuous ultrasound significantly decreased with time. Enhancement or reduction of sonochemical activity of pulsed ultrasound compared to continuous ultrasound depended on the pulse length and pulse interval.

    Full Text Available Road accidents are one of the most relevant issues in today’s society. It causes hundreds of accidents every year from over the world. Every year 1.2 million of people are killed and between 20 and 50 million people are offended due to the road accidents. Three main types of accidents in Malaysia is collision with passenger cars, collisions with other motorcycles and single-motorcycle accidents. F0050 is ranked the district with the highest road fatalities in Johor for five consecutive years. Motorcyclists and their pillion riders were the highest contributors – 60% or 648 fatalities, followed by car drivers and passengers numbering 266 fatalities. One reason of accident occurrence can be lack of road design consistency which most drivers make fewer errors in the vicinity of geometric features. Geometric design consistency is emerging as an important component in highway design relate to the safety performance. The result shows the continuous speed profiles along F0050. Since motorcyclist have a higher fatality per distance traveled, this study will develop the potential relationship between design consistency which is represented by continuous speed profiles by using Global Positioning System (GPS.

    In the irradiation test of the U-Mo dispersed nuclear fuel that is used as nuclear fuels for research reactors, it was recognized that the swelling due to reaction between U-Mo particle and Al matrix caused some failures of the fuel claddings. The development of new style nuclear fuel that could minimize the reaction between U-Mo particles and Al matrix was needed. Tube style nuclear fuel was judged to be suitable as new style nuclear fuel. We targeted to make U-Mo tube of diameter 10mm, thinner than 1mm thick, because temperature distribution of tube style nuclear fuel will be expected to have a good performance. We used continuous casting technology to make tube style nuclear fuel. In this research, we have tried to make tube using copper before we make U-Mo tube style nuclear fuel by continuous casting method. As a result of the experiment, we succeeded to make copper tube of diameter 10mm, thickness 1mm

    The demand for on-the-spot analysis is met by a miniature mass spectrometer which is preferred to be robust, stable, as small as possible and capable of analyzing different samples by coupling with various ionization methods. However, largely constrained by the atmospheric pressure interface (API), these aspects are difficult to be realized in one system. Herein, we describe the development of a new miniature mass spectrometer with balanced performance. The miniature mass spectrometer is small in size (30 × 30 × 18 cm) but has a continuous API, which was achieved by high-pressure ion trap operation and maximized ion transfer efficiency with the utilization of a differential pumping system. The miniature mass spectrometer was characterized and optimized in terms of stability, sensitivity, mass range, mass resolution and scan speed. Rapid analysis of mixtures was demonstrated by coupling the miniature mass spectrometer with the ambient ionization technique of paper spray. This is the smallest miniature mass spectrometer to date, which has a continuous API.

Methodology was refined for determining the aromatic character of hydro treated liquid, based on Nuclear Magnetic Resonance (NMR) and Fourier Transform Infrared (FTIR). Tests at GrafTech International showed that binder pitches produced using the WVU solvent extraction protocol can result in acceptable graphite electrodes for use in arc furnaces. These tests were made at the pilot scale.

    Full Text Available Laboratory conditions nullify the extrinsic factors that determine the wild expected lifespan and release the intrinsic or potential lifespan. Thus, wild animals reared in a laboratory often show an increased lifespan, and consequently an increased senescence phase. Senescence is associated with a broad suite of physiological changes, including a decreased responsiveness of the circadian system. The time-keeping hormone melatonin, an important chemical player in this system, is suspected to have an anti-aging role. The Greater White-toothed shrew Crocidura russula is an ideal study model to address questions related to aging and associated changes in biological functions: its lifespan is short and is substantially increased in captivity; daily and seasonal rhythms, while very marked the first year of life, are dramatically altered during the senescence process which starts during the second year. Here we report on an investigation of the effects of melatonin administration on locomotor activity of aging shrews.1 The diel fluctuations of melatonin levels in young, adult and aging shrews were quantified in the pineal gland and plasma. In both, a marked diel rhythm (low diurnal concentration; high nocturnal concentration was present in young animals but then decreased in adults, and, as a result of a loss in the nocturnal production, was absent in old animals. 2 Daily locomotor activity rhythm was monitored in pre-senescent animals that had received either a subcutaneous melatonin implant, an empty implant or no implant at all. In non-implanted and sham-implanted shrews, the rhythm was well marked in adults. A marked degradation in both period and amplitude, however, started after the age of 14-16 months. This pattern was considerably delayed in melatonin-implanted shrews who maintained the daily rhythm for significantly longer.This is the first long term study (>500 days observation of the same individuals that investigates the effects of

In both, a marked diel rhythm (low diurnal concentration; high nocturnal concentration) was present in young animals but then decreased in adults, and, as a result of a loss in the nocturnal production, was absent in old animals. 2) Daily locomotor activity rhythm was monitored in pre-senescent animals that had received either a subcutaneous melatonin implant, an empty implant or no implant at all. In non-implanted and sham-implanted shrews, the rhythm was well marked in adults. A marked degradation in both period and amplitude, however, started after the age of 14-16 months. This pattern was considerably delayed in melatonin-implanted shrews who maintained the daily rhythm for significantly longer. This is the first long term study (>500 days observation of the same individuals) that investigates the effects of continuous melatonin

    Several earthquakes with strong magnitude occurred globally at various locations, especially the unforgettable tsunami disaster caused by the earthquake in Indonesia and Japan. If the characteristics of structures can be well understood to implement new technology, the damages caused by most natural disasters can be significantly alleviated. In this research, dynamic digital image correlation method for using continuous parameter is applied for developing a low-cost digital image correlation coefficient method with advanced digital cameras and high-speed computers. The experimental study using cantilever test object with defect control confirms that the vibration mode calculated using this proposed method can highly express the defect locations. This proposed method combined with the sensitivity of Inter-Story Drift Mode Shape, IDMS, can also reveal the damage degree of damage structure. These test and analysis results indicate that this proposed method is high enough for applying to achieve the object of real-time online monitoring of structure. PMID:24023530

    Continuous monitor system of multiple beta-ray nuclides was designed conceptually while keeping the optimization and the automation in mind. The conincidence MCA was designed to maintain, repair and upgrade with ease. DSP was adopted to realize hardware function using software and to miniaturize the coincidence Multi Channel Analyzer (MCA). The MCA system showed 99% background rejection rate, and was applied well to gamma-ray system using {sup 60}C0. An algorithm using least square method was developed for simultaneous radioassay of multiple beta-ray nuclides. The algorithm was tested using the simulation and was applied to experimental data. The results show that the algorithm is suitable to continous monitor system of multiple beta-ray nuclides.

    Design of new continuous mixing operations poses many challenges, especially when dealing with highly viscous non-Newtonian fluids. Knowledge of complex rheological behaviour of the working mixture is crucial for development of an efficient process. In this work, we investigate the mixing performance of two different static mixers and the effects of the mixture rheology on the manufacturing of novel non-aqueous-based oral care products using experimental and computational fluid dynamic methods. The two liquid phases employed, i.e. a carbomer suspension in polyethylene glycol and glycerol, start to form a gel when they mix. We studied the structure evolution of the liquid mixture using time-resolved rheometry and we obtained viscosity rheograms at different phase ratios from pressure drop measurements in a customized mini-channel. The numerical results and rheological model were validated with experimental measurements carried out in a specifically designed setup. EPSRS-CORAL.

    The need for a continuous monitor for environmentally important pollutants at realistic [parts-per-trillon (parts in 10 12 )] concentrations measured in real time (minutes) is widely recognized. We developed an instrument that is based on supersonic-jet expansion and cooling, followed by resonantly enhanced multiphoton ionization (REMPI) into a mass spectrometer. This approach furnishes the dual selectivity of narrow-band tuned laser absorption and mass analysis. We initiated a spectroscopic characterization of the jet's collisional cooling behavior to optimize the instrument's sensitivity and selectivity, made measurements of several aromatic compounds (including polychlorinated dioxins) by use of a one-color REMPI scheme, and demonstrated a two-color excitation scheme

    The purpose of this DOE-funded effort is to develop continuous processes for solvent extraction of coal for the production of carbon products. The largest applications are those which support metals smelting, such as anodes for aluminum smelting and electrodes for arc furnaces. Other carbon products include materials used in creating fuels for the Direct Carbon Fuel Cell, and porous carbon structural material referred to as ''carbon foam'' and carbon fibers. During this reporting period, hydrotreatment of solvent was completed in preparation for pitch fabrication for graphite electrodes. Coal digestion has lagged but is expected to be complete by next quarter. Studies are reported on coal dissolution, pitch production, foam synthesis using physical blowing agents, and alternate coking techniques.

    Cultural safety in higher education learning and teaching environments is paramount to positive educational outcomes for Aboriginal and/or Torres Strait Islander (hereafter called First Peoples) students. There is a lack of research evaluating the impact of continuing professional development on midwifery academics' awareness of cultural safety. To implement and evaluate a continuing professional development intervention to improve midwifery academics' awareness of cultural safety in supporting First Peoples midwifery students success. A pre-post intervention mixed methods design was used. Academics (n=13) teaching into a Bachelor of Midwifery program agreed to participate. The intervention consisted of two workshops and five yarning circles across a semester. Data included the Awareness of Cultural Safety Scale, self-assessment on cultural safety and perceptions of racism, evaluation of the intervention, participants' journal entries, and researcher's reflections. Responses on the Awareness of Cultural Safety Scale revealed significant improvement in participants' awareness of cultural safety. There was an upward trend in self-assessment ratings. Participants reported high levels of satisfaction with the intervention or workshops and yarning circles. Participants' journal entries revealed themes willingness to participate and learn, confidence as well as anger and distress. Increased awareness of cultural safety can be transformative for midwifery academics. Workshops and yarning circles can support academics in moving beyond a 'sense of paralysis' and engage in challenging conversations to transform their learning and teaching and in turn foster a culturally safe learning and teaching environment for First Peoples midwifery students towards success.

    Pei, Jin-Song; Mai, Eric C.

    2007-04-01

    This paper introduces a continuous effort towards the development of a heuristic initialization methodology for constructing multilayer feedforward neural networks to model nonlinear functions. In this and previous studies that this work is built upon, including the one presented at SPIE 2006, the authors do not presume to provide a universal method to approximate arbitrary functions, rather the focus is given to the development of a rational and unambiguous initialization procedure that applies to the approximation of nonlinear functions in the specific domain of engineering mechanics. The applications of this exploratory work can be numerous including those associated with potential correlation and interpretation of the inner workings of neural networks, such as damage detection. The goal of this study is fulfilled by utilizing the governing physics and mathematics of nonlinear functions and the strength of the sigmoidal basis function. A step-by-step graphical procedure utilizing a few neural network prototypes as "templates" to approximate commonly seen memoryless nonlinear functions of one or two variables is further developed in this study. Decomposition of complex nonlinear functions into a summation of some simpler nonlinear functions is utilized to exploit this prototype-based initialization methodology. Training examples are presented to demonstrate the rationality and effciency of the proposed methodology when compared with the popular Nguyen-Widrow initialization algorithm. Future work is also identfied.

    Full Text Available Learners in South African schools have been found to perform poorly in mathematics because they do not understand the language used in solving mathematical problems. In order to improve academic performance teachers need to be made aware of the importance of language in the development of numeracy. A continued professional development (CPD programme addressed this need. The purpose of the research was to understand how the participants implemented the strategies developed during the programme and how they perceived the support provided by the programme. The research was conducted over 2 years in semi-rural and urban contexts. As part of a more comprehensive mixed method study, the qualitative data referred to in this article were obtained through open-ended questions in questionnaires, focus groups, reflections in portfolios, and a research diary. Results showed that numeracy terminology was often used by learners that differed from standard terminology prescribed by the curriculum. The participants themselves did not necessarily understand the numeracy terminology and thus found it a challenge to implement curriculum outcomes. Issues related to language use of the participants in teaching numeracy were associated with the lack of resources available in the language of learning and teaching  (LoLT. Some of the participants taught numeracy in English, rather than LoLT. The results indicated low teacher expectations of the learners. The CPD programme was considered valuable and effective. SLPs in schools need to be expand their role to provide CPD opportunities for teachers.

    Within the apprenticeship model of general practice training, the majority of teaching and learning occurs in the practice under the guidance of the general practice supervisor. One of the foundations of a high-quality general practice training program is the delivery of relevant, evidence-based educational continuing professional development (EdCPD) for general practice supervisors. Despite The Royal Australian College of General Practitioners (RACGP) and the Australian College of Rural and Remote Medicine (ACRRM) standards requiring EdCPD, there is currently no standardised educational curriculum for Australian general practice supervisors. There are a number of emerging themes with significant implications for future general practice supervisor EdCPD. These include clinical supervision and structural issues, capacity constraints, and emerging educational issues. We propose the development of a core curriculum for general practice supervisors that is competency-based and evidence-based, and reflects the changing landscape of Australian general practice training. A national general practice supervisor core curriculum would provide standardisation, encourage collaboration, allow for regional adaptation, focus on developing competencies and require rigorous evaluation.

    Full Text Available The teacher Continuing Professional Development (CPD requires today the re-thinking of teachersʼ expertise, in connection to a new definition of professional competence. For example, in the case of technology competences, the continuing training shouldn’t be limited to promoting their learning and practice, however to encourage the re-thinking of the sense and the value of personal agency, that allows to express the competences acquired and link them into an authentic and self-determined dimension. This project research examines the correlation between the pre-school teachers continuing professional development and the agency’s capability processes, trying to define how technologies can affect the professional agency’s qualification. First evidences about the increased value acquired by the extracurricular aspects of networking and governance suggest how teachers’ agency appears focused on interaction with enlarged learning contexts, suggesting the opportunity to invest in socio-relational aspects and integrate them into traditional professional education and training processes.Competenze tecnologiche, agency e sfide collaborative: dall’expertise allo sviluppo professionale docenteLo sviluppo professionale degli insegnanti richiede oggi il ripensamento dellʼexpertise docente nel dialogo con una nuova definizione della competenza professionale.

    High-intensity pulsed electric field (HIPEF) is a non-thermal food processing technology that is currently being investigated to inactivate microorganisms and certain enzymes, involving a limited increase of food temperature. Promising results have been obtained on the inactivation of microbial enzymes in milk when suspended in simulated milk ultrafiltrate. The aim of this study was to evaluate the effectiveness of continuous HIPEF equipment on inactivating a protease from Bacillus subtilis inoculated in milk. Samples were subjected to HIPEF treatments of up to 866 micros of squared wave pulses at field strengths from 19.7 to 35.5 kV/cm, using a treatment chamber that consisted of eight colinear chambers connected in series. Moreover, the effects of different parameters such as pulse width (4 and 7 micros), pulse repetition rates (67, 89, and 111 Hz), and milk composition (skim and whole milk) were tested. Protease activity decreased with increased treatment time or field strength and pulse repetition rate. Regarding pulse width, no differences were observed between 4 and 7 micros pulses when total treatment time was considered. On the other hand, it was observed that milk composition affected the results since higher inactivation levels were reached in skim than in whole milk. The maximum inactivation (81%) was attained in skim milk after an 866-micros treatment at 35.5 kV/cm and 111 Hz.

    The generation of hybrid materials based on β-tricalcium phosphate (TCP) and various biodegradable polymers like poly(L-lactide-co-D,L-lactide) (PLA) represents a common approach to overcoming the disadvantages of pure TCP devices. These disadvantages lie in TCP's mechanical properties, such as brittleness. The positive characteristic of PLA — improvement of compressive strength of calcium phosphate scaffolds – is diametrically opposed to its cell attractiveness. Therefore, the objective of this work was to optimize osteoblast migration and cellularization inside a three-dimensionally (3D) printed, PLA polymer stabilized TCP hybrid scaffold by a plasma polymer process depositing amino groups via allylamine. MG-63 osteoblastic cells inside the 10 mm hybrid scaffold were dynamically cultivated for 14 days in a 3D model system integrated in a perfusion reactor. The whole TCP/PLA hybrid scaffold was continuously colonized due to plasma polymerized allylamine activation inducing the migration potential of osteoblasts. - Highlights: • Mechanical stabilization of β-tricalcium phosphate scaffolds by PLA infiltration • Hybrid scaffolds with higher cell attraction due to plasma polymerized allylamine • 3D perfusion in vitro model for observation of cell migration inside scaffolds • Enhanced cell migration within plasma polymer coated TCP hybrid scaffolds

    The corticospinal and rubrospinal systems function in skilled movement control. A key question is how do these systems develop the capacity to coordinate their motor functions and, in turn, if the red nucleus/rubrospinal tract (RN/RST) compensates for developmental corticospinal injury? We used the cat to investigate whether the developing rubrospinal system is shaped by activity-dependent interactions with the developing corticospinal system. We unilaterally inactivated M1 by muscimol microinfusion between postnatal weeks 5 and 7 to examine activity-dependent interactions and whether the RN/RST compensates for corticospinal tract (CST) developmental motor impairments and CST misprojections after M1 inactivation. We examined the RN motor map and RST cervical projections at 7 weeks of age, while the corticospinal system was inactivated, and at 14 weeks, after activity returned. During M1 inactivation, the RN on the same side showed normal RST projections and reduced motor thresholds, suggestive of precocious development. By contrast, the RN on the untreated/active M1 side showed sparse RST projections and an immature motor map. After M1 activity returned later in adolescent cat development, RN on the active M1/CST side continued to show a substantial loss of spinal terminations and an impaired motor map. RN/RST on the inactivated side regressed to a smaller map and fewer axons. Our findings suggest that the developing rubrospinal system is under activity-dependent regulation by the corticospinal system for establishing mature RST connections and RN motor map. The lack of RS compensation on the non-inactivated side can be explained by development of ipsilateral misprojections from the active M1 that outcompete the RST. Significance statement: Skilled movements reflect the activity of multiple descending motor systems and their interactions with spinal motor circuits. Currently, there is little insight into whether motor systems interact during development to

    Increasingly, the use of web database portfolio systems is noted in medical and health education, and for continuing professional development (CPD). However, the functions of existing systems are not always aligned with the corresponding pedagogy and hence reflection is often lost. This paper presents the development of a tailored web database portfolio system with Picture Archiving and Communication System (PACS) connectivity, which is based on the portfolio pedagogy. Following a pre-determined portfolio framework, a system model with the components of web, database and mail servers, server side scripts, and a Query/Retrieve (Q/R) broker for conversion between Hypertext Transfer Protocol (HTTP) requests and Q/R service class of Digital Imaging and Communication in Medicine (DICOM) standard, is proposed. The system was piloted with seventy-seven volunteers. A tailored web database portfolio system (http://radep.hti.polyu.edu.hk) was developed. Technological arrangements for reinforcing portfolio pedagogy include popup windows (reminders) with guidelines and probing questions of 'collect', 'select' and 'reflect' on evidence of development/experience, limitation in the number of files (evidence) to be uploaded, the 'Evidence Insertion' functionality to link the individual uploaded artifacts with reflective writing, capability to accommodate diversity of contents and convenient interfaces for reviewing portfolios and communication. Evidence to date suggests the system supports users to build their portfolios with sound hypertext reflection under a facilitator's guidance, and with reviewers to monitor students' progress providing feedback and comments online in a programme-wide situation.

    2012-12-01

    Archives of digital seismic data recorded by seismometer networks around the world have grown tremendously over the last several decades helped by the deployment of seismic stations and their continued operation within the framework of monitoring earthquake activity and verification of the Nuclear Test-Ban Treaty. We show results from our continuing effort in developing efficient waveform cross-correlation and double-difference analysis methods for the large-scale processing of regional and global seismic archives to improve existing earthquake parameter estimates, detect seismic events with magnitudes below current detection thresholds, and improve real-time monitoring procedures. We demonstrate the performance of these algorithms as applied to the 28-year long seismic archive of the Northern California Seismic Network. The tools enable the computation of periodic updates of a high-resolution earthquake catalog of currently over 500,000 earthquakes using simultaneous double-difference inversions, achieving up to three orders of magnitude resolution improvement over existing hypocenter locations. This catalog, together with associated metadata, form the underlying relational database for a real-time double-difference scheme, DDRT, which rapidly computes high-precision correlation times and hypocenter locations of new events with respect to the background archive (http://ddrt.ldeo.columbia.edu). The DDRT system facilitates near-real-time seismicity analysis, including the ability to search at an unprecedented resolution for spatio-temporal changes in seismogenic properties. In areas with continuously recording stations, we show that a detector built around a scaled cross-correlation function can lower the detection threshold by one magnitude unit compared to the STA/LTA based detector employed at the network. This leads to increased event density, which in turn pushes the resolution capability of our location algorithms. On a global scale, we are currently building

    Atmospheric electric activity measurements have been recorded continuously by a punctual lightning system at a tropical highland observatory from 1988 onwards, and were analyzed to obtain lightning statistical confident results for thunderstorms occurrence on the leeward side of the southern mountain ridge of Mexico's Valley. Shown, as examples, are individual profiles of the atmospheric electrical activity, associated with severe storms. The results make clear that the fastest possible sequence of electrical measurements is required to obtain significant and applications oriented data in connection with a whole series of thunderstorms taking into account the mean time variation of the atmospheric electricity measurements at an altitude of 2270 m a.s.l. The seasonal variation indicates that the lightning flash peak currents were found to be larger in summer with less than 10% occurring in the autumn and winter.

    A systematic framework is proposed for the design of continuous pharmaceutical manufacturing processes. Specifically, the design framework focuses on organic chemistry based, active pharmaceutical ingredient (API) synthetic processes, but could potentially be extended to biocatalytic and fermentation-based products. The method exploits the synergic combination of continuous flow technologies (e.g., microfluidic techniques) and process systems engineering (PSE) methods and tools for faster process design and increased process understanding throughout the whole drug product and process development cycle. The design framework structures the many different and challenging design problems (e.g., solvent selection, reactor design, and design of separation and purification operations), driving the user from the initial drug discovery steps--where process knowledge is very limited--toward the detailed design and analysis. Examples from the literature of PSE methods and tools applied to pharmaceutical process design and novel pharmaceutical production technologies are provided along the text, assisting in the accumulation and interpretation of process knowledge. Different criteria are suggested for the selection of batch and continuous processes so that the whole design results in low capital and operational costs as well as low environmental footprint. The design framework has been applied to the retrofit of an existing batch-wise process used by H. Lundbeck A/S to produce an API: zuclopenthixol. Some of its batch operations were successfully converted into continuous mode, obtaining higher yields that allowed a significant simplification of the whole process. The material and environmental footprint of the process--evaluated through the process mass intensity index, that is, kg of material used per kg of product--was reduced to half of its initial value, with potential for further reduction. The case-study includes reaction steps typically used by the pharmaceutical

    Full Text Available In this work, a hybrid MPC (model predictive control-PID (proportional-integral-derivative control system has been designed for the continuous purification and processing framework of active pharmaceutical ingredients (APIs. The specific unit operations associated with the purification and processing of API have been developed from first-principles and connected in a continuous framework in the form of a flowsheet model. These integrated unit operations are highly interactive along with the presence of process delays. Therefore, a hybrid MPC-PID is a promising alternative to achieve the desired control loop performance as mandated by the regulatory authorities. The integrated flowsheet model has been simulated in gPROMSTM (Process System Enterprise, London, UK. This flowsheet model has been linearized in order to design the control scheme. The ability to track the set point and reject disturbances has been evaluated. A comparative study between the performance of the hybrid MPC-PID and a PID-only control scheme has been presented. The results show that an enhanced control loop performance can be obtained under the hybrid control scheme and demonstrate that such a scheme has high potential in improving the efficiency of pharmaceutical manufacturing operations.

    Full Text Available The purpose of this study was to investigate the effect of continuous exercise and lifestyle-embedded physical activity upon glucose regulation, and assess the feasibility of seven day continuous glucose monitoring (CGM in a normoglycaemic individual. One physically active non-diabetic male [age: 22 y; mass: 71.5 kg; height: 181 cm] underwent 7 days CGM, performing 3 trial conditions: a sedentary control (< 2500 steps, pedometer controlled, a continuous exercise condition (2 x 30 min treadmill running at 70% HRmax, and a lifestyleembedded physical activity condition (100 min fractionalized moderate activity. Diet was standardised andphysical activity levels were monitored via accelerometry throughout. Results showed a significant difference of -0.24 mmol.dL-1 in twenty-four hour mean glucose levels between the sedentary and continuous condition (p = 0.00, and a significant difference of -0.038 mmol.L-1 in twenty-four hour mean glucose levels between thesedentary and lifestyle embedded physical activity condition (p = 0.004.

  6. Water activity control: a way to improve the efficiency of continuous lipase esterification.

    During continuous lipase-catalyzed oleic acid esterification by ethanol in n-hexane, the oleic acid conversion, initially at 95%, decreases to 20% after 2 h. This decrease is caused by the accumulation of the water produced in the course of the reaction in the packed-bed reactor (PBR). In order to improve the PBR efficiency, it is necessary to evacuate the water produced. In this study, different approaches have been tested to control the water content in the PBR during continuous esterification. The first approach consisted in improving the water solubility by increasing the reaction medium polarity. The addition of polar additives to n-hexane, the use of more polar solvents, and the use of solvent-free reaction medium were tested as a means to favor the water evacuation from the PBR. First of all, the use ofn-hexane supplemented with acetone (3 M) or 2-methyl-2-propanol (1 M) enabled the conversion to be maintained at higher values than those obtained in pure n-hexane. The replacement of n-hexane by a more polar solvent, like the 5-methyl-2-hexanone, resulted in the same effect. In all cases, conversions at steady-state were always less than 95%, as obtained in pure n-hexane. This is explained by a decrease in the enzyme activity due to the increase in the medium polarity. Nevertheless, an increase in enzyme quantity allowed 90% conversion to be maintained during 1 week using 3 M acetone amended n-hexane. Good results (a steady-state conversion of about 80%) were obtained when esterification was carried out in a solvent-free reaction medium containing 2 M 2-methyl-2-propanol as a polar additive. The second approach consisted in the evaporation of the accumulated water by use of an intermittent airflow. Although this process did not enable constant esterification rate to be maintained, it did enable the initial conversion (95%) to be restored intermittently. Copyright 1998 John Wiley & Sons, Inc.

    The evolution of oral teeth is considered a major contributor to the overall success of jawed vertebrates. This is especially apparent in cartilaginous fishes including sharks and rays, which develop elaborate arrays of highly specialized teeth, organized in rows and retain the capacity for life-long regeneration. Perpetual regeneration of oral teeth has been either lost or highly reduced in many other lineages including important developmental model species, so cartilaginous fishes are uniquely suited for deep comparative analyses of tooth development and regeneration. Additionally, sharks and rays can offer crucial insights into the characters of the dentition in the ancestor of all jawed vertebrates. Despite this, tooth development and regeneration in chondrichthyans is poorly understood and remains virtually uncharacterized from a developmental genetic standpoint. Using the emerging chondrichthyan model, the catshark (Scyliorhinus spp.), we characterized the expression of genes homologous to those known to be expressed during stages of early dental competence, tooth initiation, morphogenesis, and regeneration in bony vertebrates. We have found that expression patterns of several genes from Hh, Wnt/β-catenin, Bmp and Fgf signalling pathways indicate deep conservation over ~450 million years of tooth development and regeneration. We describe how these genes participate in the initial emergence of the shark dentition and how they are redeployed during regeneration of successive tooth generations. We suggest that at the dawn of the vertebrate lineage, teeth (i) were most likely continuously regenerative structures, and (ii) utilised a core set of genes from members of key developmental signalling pathways that were instrumental in creating a dental legacy redeployed throughout vertebrate evolution. These data lay the foundation for further experimental investigations utilizing the unique regenerative capacity of chondrichthyan models to answer evolutionary

    Endovascular simulation employing computer, animal, and static models are common and useful adjuncts for teaching endovascular procedures and developing novel, complex endovascular techniques. Unfortunately, these models lack realistic haptic feedback and thus do not faithfully replicate many of the technical challenges associated with clinical endovascular procedures (e.g., arterial calcification, rigidity, and stenosis). We sought to develop a realistic and reproducible perfused cadaver model for endovascular training, device development, and research. Fresh frozen, elderly (age 50-80 years) male cadavers were thawed and prepared for open dissection. The entire arterial tree (ascending aorta to femoral arteries) was dissected free and major branch vessels exposed. Sheaths were placed to allow outflow from selected vessels. A Dacron conduit was sewn to the ascending aorta to generate arterial inflow, which was provided by a centrifugal pump. Aortic aneurysms were created in the descending thoracic and abdominal aorta. Digital subtraction arteriography and various endovascular interventions were performed, including stent grafts and EndoAnchors deployment. Continuous antegrade flow was achieved in the thoracic, abdominal, iliac, and femoral segments. Open and percutaneous access at the femoral region was obtained with realistic back-bleeding and tactile feedback. Adequate, fluoroscopically documented flow was observed in both cannulated major and noncannulated smaller branches. We performed angiography with standard techniques via a pigtail catheter and contrast injector throughout the arterial system. Abdominal and thoracic endografts were deployed with appropriate angiographic guidance and realistic haptic feedback for both guidewire and stent grafts. Additional applications, including selective cannulation, aorto-iliac occlusive disease interventions, and anchor placement, were also successfully simulated. Finally, the model was used as a platform to test

    Full Text Available The front end of any modern ion accelerator includes a radio frequency quadrupole (RFQ. While many pulsed ion linacs successfully operate RFQs, several ion accelerators worldwide have significant difficulties operating continuous wave (CW RFQs to design specifications. In this paper we describe the development and results of the beam commissioning of a CW RFQ designed and built for the National User Facility: Argonne Tandem Linac Accelerator System (ATLAS. Several innovative ideas were implemented in this CW RFQ. By selecting a multisegment split-coaxial structure, we reached moderate transverse dimensions for a 60.625-MHz resonator and provided a highly stabilized electromagnetic field distribution. The accelerating section of the RFQ occupies approximately 50% of the total length and is based on a trapezoidal vane tip modulation that increased the resonator shunt impedance by 60% in this section as compared to conventional sinusoidal modulation. To form an axially symmetric beam exiting the RFQ, a very short output radial matcher with a length of 0.75βλ was developed. The RFQ is designed as a 100% oxygen-free electronic (OFE copper structure and fabricated with a two-step furnace brazing process. The radio frequency (rf measurements show excellent rf properties for the resonator, with a measured intrinsic Q equal to 94% of the simulated value for OFE copper. An O^{5+} ion beam extracted from an electron cyclotron resonance ion source was used for the RFQ commissioning. In off-line beam testing, we found excellent coincidence of the measured beam parameters with the results of beam dynamics simulations performed using the beam dynamics code TRACK, which was developed at Argonne. These results demonstrate the great success of the RFQ design and fabrication technology developed here, which can be applied to future CW RFQs.

  10. The cascade model of teachers’ continuing professional development in Kenya: A time for change?

    Full Text Available Kenya is one of the countries whose teachers the UNESCO (2015 report cited as lacking curriculum support in the classroom. As is the case in many African countries, a large portion of teachers in Kenya enter the teaching profession when inadequately prepared, while those already in the field receive insufficient support in their professional lives. The cascade model has often been utilized in the country whenever need for teachers’ continuing professional development (TCPD has arisen, especially on a large scale. The preference for the model is due to, among others, its cost effectiveness and ability to reach out to many teachers within a short period of time. Many researchers have however cast aspersions with this model for its glaring shortcomings. On the contrary, TCPD programmes that are collaborative in nature and based on teachers’ contexts have been found to be more effective than those that are not. This paper briefly examines cases of the cascade model in Kenya, the challenges associated with this model and proposes the adoption of collaborative and institution-based models to mitigate these challenges. The education sectors in many nations in Africa, and those in the developing world will find the discussions here relevant.

    This NETL sponsored effort seeks to develop continuous technologies for the production of carbon products, which may be thought of as the heavier products currently produced from refining of crude petroleum and coal tars obtained from metallurgical grade coke ovens. This effort took binder grade pitch, produced from liquefaction of West Virginia bituminous grade coal, all the way to commercial demonstration in a state of the art arc furnace. Other products, such as crude oil, anode grade coke and metallurgical grade coke were demonstrated successfully at the bench scale. The technology developed herein diverged from the previous state of the art in direct liquefaction (also referred to as the Bergius process), in two major respects. First, direct liquefaction was accomplished with less than a percent of hydrogen per unit mass of product, or about 3 pound per barrel or less. By contrast, other variants of the Bergius process require the use of 15 pounds or more of hydrogen per barrel, resulting in an inherent materials cost. Second, the conventional Bergius process requires high pressure, in the range of 1500 psig to 3000 psig. The WVU process variant has been carried out at pressures below 400 psig, a significant difference. Thanks mainly to DOE sponsorship, the WVU process has been licensed to a Canadian Company, Quantex Energy Inc, with a commercial demonstration unit plant scheduled to be erected in 2011.

    Limitations in healthcare worker (HCW) capacity compound the burden of dual TB and HIV epidemics in sub-Saharan Africa. To fill gaps in knowledge and skills, effective continuing profession development (CPD) initiatives are needed to support practicing HCWs reach high standards of care. e-learning opportunities can bring expert knowledge to HCWs in the field and provide a flexible learning option adaptable to local settings. Few studies provide insight into HCW experiences with online CPD in the developing country context. An online survey using both close-ended and free response was conducted to HCWs in sub-Saharan Africa who completed the University of Washington (UW) School of Medicine online graduate course, "Clinical Management of HIV." Associations between respondent characteristics (age, gender, rural/urban, job title) and learning preferences, course barriers, and facilitators with an emphasis on online courses were examined using chi-square. Covariates significant at the p online course from work, noting that slow (55%) or limited (41%) internet as well as lack of time (53%) were barriers to course completion. Women (p online courses by noting the knowledge gains, the flexibility of format, a desire for recognition of course completion, and a request for additional online coursework. Online CPD opportunities were accepted across a diverse group of HCWs from sub-Saharan Africa and should be expanded to provide more flexible opportunities for self-initiated learning; however, these need to be responsive to the limited resources of those who seek these courses.

    Patient condition is a key element in communication between clinicians. However, there is no generally accepted definition of patient condition that is independent of diagnosis and that spans acuity levels. We report the development and validation of a continuous measure of general patient condition that is independent of diagnosis, and that can be used for medical-surgical as well as critical care patients. A survey of Electronic Medical Record data identified common, frequently collected non-static candidate variables as the basis for a general, continuously updated patient condition score. We used a new methodology to estimate in-hospital risk associated with each of these variables. A risk function for each candidate input was computed by comparing the final pre-discharge measurements with 1-year post-discharge mortality. Step-wise logistic regression of the variables against 1-year mortality was used to determine the importance of each variable. The final set of selected variables consisted of 26 clinical measurements from four categories: nursing assessments, vital signs, laboratory results and cardiac rhythms. We then constructed a heuristic model quantifying patient condition (overall risk) by summing the single-variable risks. The model's validity was assessed against outcomes from 170,000 medical-surgical and critical care patients, using data from three US hospitals. Outcome validation across hospitals yields an area under the receiver operating characteristic curve(AUC) of ≥0.92 when separating hospice/deceased from all other discharge categories, an AUC of ≥0.93 when predicting 24-h mortality and an AUC of 0.62 when predicting 30-day readmissions. Correspondence with outcomes reflective of patient condition across the acuity spectrum indicates utility in both medical-surgical units and critical care units. The model output, which we call the Rothman Index, may provide clinicians with a longitudinal view of patient condition to help address known

  3. Continued expression of GATA3 is necessary for cochlear neurosensory development.

    Directory of Open Access Journals (Sweden)

    Jeremy S Duncan

    Full Text Available Hair cells of the developing mammalian inner ear are progressively defined through cell fate restriction. This process culminates in the expression of the bHLH transcription factor Atoh1, which is necessary for differentiation of hair cells, but not for their specification. Loss of several genes will disrupt ear morphogenesis or arrest of neurosensory epithelia development. We previously showed in null mutants that the loss of the transcription factor, Gata3, results specifically in the loss of all cochlear neurosensory development. Temporal expression of Gata3 is broad from the otic placode stage through the postnatal ear. It therefore remains unclear at which stage in development Gata3 exerts its effect. To better understand the stage specific effects of Gata3, we investigated the role of Gata3 in cochlear neurosensory specification and differentiation utilizing a LoxP targeted Gata3 line and two Cre lines. Foxg1(Cre∶Gata3(f/f mice show recombination of Gata3 around E8.5 but continue to develop a cochlear duct without differentiated hair cells and spiral ganglion neurons. qRT-PCR data show that Atoh1 was down-regulated but not absent in the duct whereas other hair cell specific genes such as Pou4f3 were completely absent. In addition, while Sox2 levels were lower in the Foxg1(Cre:Gata3(f/f cochlea, Eya1 levels remained normal. We conclude that Eya1 is unable to fully upregulate Atoh1 or Pou4f3, and drive differentiation of hair cells without Gata3. Pax2-Cre∶Gata3(f/f mice show a delayed recombination of Gata3 in the ear relative to Foxg1(Cre:Gata3(f/f . These mice exhibited a cochlear duct containing patches of partially differentiated hair cells and developed only few and incorrectly projecting spiral ganglion neurons. Our conditional deletion studies reveal a major role of Gata3 in the signaling of prosensory genes and in the differentiation of cochlear neurosenory cells. We suggest that Gata3 may act in combination with Eya1, Six1, and

    The design and development of the Air Force and TRW's Advanced Control Technology Experiment (ACTEX) flight experiment is described in this paper. The overall objective of ACTEX is to provide an active structure trailblazer which will demonstrate the compatibility of active structures with operational spacecraft performance and lifetime measures. At the heart of the experiment is an active tripod driven by a digitally-programmable analog control electronics subsystem. Piezoceramic sensors and actuators embedded in a graphite epoxy host material provide the sensing and actuation mechanism for the active tripod. Low noise ground-programmable electronics provide a virtually unlimited number of control schemes that can be implemented in the space environment. The flight experiment program provides the opportunity to gather performance, reliability, adaptability, and lifetime performance data on vibration suppression hardware for the next generation of DoD and NASA spacecraft.

    2009-01-01

    This project revitalised continuing professional development (CPD) among rural health professionals in Uganda, Africa, using information and communication technology (ICT). The project was piloted in 3 rural hospitals where CPD activities were failing to meet demand because activities were not properly coordinated, the meetings were too infrequent, the delivery methods were inappropriate, and the content was highly supply-driven and generally irrelevant to the performance needs of the health workers. The project intervention involved the installation of various ICT equipment including computers, liquid crystal display (LCD) projectors, office copiers, printers, spiral binders and CDs. A number of health workers were also trained in ICT use. Three years later, an evaluation study was conducted using interviews, focus group discussions and document review. The results indicated that there had been a rapid increase in the number of staff attending the CPD sessions, an increased staff mix among participants, improved quality of CPD presentations, increased use of locally produced content, more relevant topics discussed and an increased interest by hospital management in CPD, manifested by commitment of staff training funds. Staff motivation, attitude and responsiveness to clients had also improved as a result of the invigorated CPD activities.

However, many domestic enterprises follow the «conservative» paths of development, the essence of which is to maximize the preservation of existing company structures, technology of production, even in the transition to the new generation of products. Such a scenario for many years preserves the situation of backwardness of the domestic industry from the leading countries of the West. The way out of this situation - a complete overhaul of the company based on innovation. Therefore, the development of industrial design is one of the main stimulating factors of innovative development of Russia. Be aware that the development of the innovation sector through which progress

    Qualitative study to identify themes and explore mechanisms underlying recovery of hand function post stroke for individuals discharged from rehabilitation services. Post-stroke hemiparesis frequently results in persistent hand dysfunction; the mechanisms of functional recovery are however poorly understood. We assessed the perspectives of community-dwelling individuals with chronic stroke on their hand function limitations and recovery to explore the feasibility of developing a theoretical framework for understanding the process of continued post-stroke recovery. Eight subjects with chronic post-stroke hemiparesis were interviewed and videotaped while they performed a battery of 20 upper limb tasks. Qualitative analysis consisted of two investigators independently reviewing the videotapes and reading the transcribed conversations, identifying significant issues and then comparing their observations to determine common themes and develop emerging concepts. Four core themes pertaining to impairment and recovery of task-specific ability emerged: 1) spasticity can be overcome actively through task-specific attempts to use the affected arm and hand; 2) use of the affected arm can be facilitated by adopting positions that reduce the effect of gravity on the arm or enable gravity to act as a natural assist in the movement; 3) task-specific skill can be attained by repeatedly attempting specific component movements of tasks in the context of a variety of different tasks; and 4) frustration impedes task performance but a mental state of 'detached focus' can improve the motivation to use the affected arm. These themes suggest a therapeutic framework for continued upper limb rehabilitation in patients' own environment to maximize functional recovery in individuals long after their stroke, and generate hypotheses which may lead to the development of new therapeutic protocols.

    For some multicomponent mixtures, where detailed chemical analysis is not feasible, the compositio of the mixture may be described by a continuous distribution function of some convenient macroscopic property suc as normal boiling point or molecular weight. To attain a quantitative description of phase equilibria for such mixtures, this work has developed thermodynamic procedures for continuous systems; that procedure is called continuous thermodynamics. To illustrate, continuous thermodynamics is used to calculate dew points for natural-gas mixtures, solvent loss in a high-pressure absorber, and liquid-liquid phase equilibria in a polymer fractionation process. Continuous thermodynamics provides a rational method for calculating phase equilibria for those mixtures where complete chemical analysis is not available but where composition can be given by some statistical description. While continuous thermodynamics is only the logical limit of the well-known pseudo-component method, it is more efficient than that method because it is less arbitrary and it often requires less computer time

    Air Products has undertaken a research program to fabricate and evaluate gas separation membranes based upon promising ``active-transport`` (AT) materials recently developed in our laboratories. Active Transport materials are ionic polymers and molten salts which undergo reversible interaction or reaction with ammonia and carbon dioxide. The materials are useful for separating these gases from mixtures with hydrogen. Moreover, AT membranes have the unique property of possessing high permeability towards ammnonia and carbon dioxide but low permeability towards hydrogen and can thus be used to permeate these components from a gas stream while retaining hydrogen at high pressure.

    To explore the perspectives of leaders in psychiatry and continuing professional development (CPD) regarding the relationship, opportunities, and challenges in integrating quality improvement (QI) and CPD. In 2013-2014, the authors interviewed 18 participants in Canada: 10 psychiatrists-in-chief, 6 CPD leaders in psychiatry, and 2 individuals with experience integrating these domains in psychiatry who were identified through snowball sampling. Questions were designed to identify participants' perspectives about the definition, relationship, and integration of QI and CPD in psychiatry. Interviews were recorded and transcribed. An iterative, inductive method was used to thematically analyze the transcripts. To ensure the rigor of the analysis, the authors performed member checking and sampling until theoretical saturation was achieved. Participants defined QI as a concept measured at the individual, hospital, and health care system levels and CPD as a concept measured predominantly at the individual and hospital levels. Four themes related to the relationship between QI and CPD were identified: challenges with QI training, adoption of QI into the mental health care system, implementation of QI in CPD, and practice improvement outcomes. Despite participants describing QI and CPD as mutually beneficial, they expressed uncertainty about the appropriateness of aligning these domains within a mental health care context because of the identified challenges. This study identified challenges with aligning QI and CPD in psychiatry and yielded a framework to inform future integration efforts. Further research is needed to determine the generalizability of this framework to other specialties and health care professions.

    2008-01-01

    This article is based on an exploratory, interpretative grounded theory study that looked at practitioners' perceptions of continuing professional development (CPD) in diagnostic radiography in the UK. Using a combination of in-depth interviews and secondary analysis of published material, a dynamic CPD process model was generated. The study aimed to explore what radiographers understood by the term CPD and whether it was perceived to have any impact on clinical practice. The study aimed to identify and investigate the components of CPD and how they interact with one another, to help to explain what is happening within CPD and what contributes to its effectiveness. The CPD process was shown to be complex, dynamic and centred on the Individual. Supporting components of Facilitation and External Influences were identified as important in maximising the potential impact of CPD. The three main categories were shown to interact dynamically and prior to Participation were shown to have a 'superadditive' effect, where the total effect was greater than the sum of the three individual parts. This study showed that radiographers are generally unaware of the holistic concept of CPD, using instead narrow definitions of CPD with little or no expectation of any impact on practice, focusing predominantly on personal gain. The model produced in the study provided a tool that practitioners reported was helpful in reflecting on their own involvment in CPD

    Two methods for calculating eigenvalue sensitivity coefficients in continuous-energy Monte Carlo applications were implemented in the KENO code within the SCALE code package. The methods were used to calculate sensitivity coefficients for several criticality safety problems. The 2 methods are: the Iterated Fission Probability (IFP) method and the newly developed Contribution-Linked eigenvalue sensitivity/Uncertainty estimation via Track-length importance Characterization (CLUTCH) method. Unlike MG TSUNAMI, the IFP and CLUTCH methods avoid directly simulating adjoint particle histories by instead storing additional information about each particle that is later used to determine the importance of the particle during its lifetime. The IFP method uses this information to estimate the importance of events according to the concept that the importance of an event is proportional to the population of neutrons present in the system during some future generation. The CLUTCH method calculates the importance of events during a particle's lifetime by examining how many fission neutrons are created by that particle after those events occur. Both methods have produced sensitivity coefficients that agreed well with reference direct perturbation sensitivity coefficients although some differences were observed around energies corresponding to large neutron capture resonances. The CLUTCH method has been consistently more efficient than the IFP method and has required less memory that the IFP and MG TSUNAMI methods

    The purpose of this study was to discover the frequency and type of use of online resources for continuing professional development displayed by physiotherapists in the UK. Therapists' skills, needs and frustrations using these resources were explored. With the relatively recent release and saturated use of the internet the potential presence of a skills gap between therapists at different stages of their career was also investigated. National online survey study. The online survey was carried out using the international online service 'Survey Monkey'. 774 physiotherapists from students to band 8c completed the survey. The online survey was advertised through Frontline, the Interactive Chartered Society of Physiotherapy, Journal of Physiotherapy Pain Association and cascade email through research and other networks. Most physiotherapists reported using the internet for professional purposes daily (40%) or 2 to 4 times a week (37%), with only 8% of respondents using it less than once a week. Overall the results suggest band 6 and 7 physiotherapists had the least skills and most frustrations when using online search engines. History and the nature of rapid technological advancement, specifically of the internet, appears to have created a generational skills gap within the largest group of the physiotherapy workforce band 6 and 7 therapists. Students, band 5 and band 8a therapists appear to most successfully use online resources and the reasons for this are explored. Copyright © 2012 Chartered Society of Physiotherapy.

    Results from two-dimensional chemistry-transport models have been used to predict the future behavior of ozone in the stratosphere. Since the transport circulation, temperature, and aerosol surface area are fixed in these models, they cannot account for the effects of changes in these quantities, which could be modified because of ozone redistribution and/or other changes in the troposphere associated with climate changes. Interactive two-dimensional models, which calculate the transport circulation and temperature along with concentrations of the chemical species, could provide answers to complement the results from three-dimension model calculations. In this project, we performed the following tasks in pursuit of the respective goals: (1) We continued to refine the 2-D chemistry-transport model; (2) We developed a microphysics model to calculate the aerosol loading and its size distribution; (3) The treatment of physics in the AER 2-D interactive model were refined in the following areas--the heating rate in the troposphere, and wave-forcing from propagation of planetary waves.

    There is little information available on journal based verifiable continuing professional development (CPD). The aim of this study was to survey those dentists who have undertaken this form of CPD and elicit their views. A questionnaire survey. Four hundred dentists who had registered to undertake CPD with the British Dental Journal (BDJ) were randomly selected and sent a questionnaire. Three hundred and twelve questionnaires were returned (78%) of these 181 (58%) were male and 131 (42%) were female. Of the 312, 307 had undertaken the BDJ CPD initiative. Two hundred and sixty eight respondents (87.3%) agreed/strongly agreed that the BDJ CPD satisfied their personal CPD needs. Two hundred and eighty three (92.2%) agreed/strongly agreed that their knowledge has been increased as a result of undertaking the BDJ CPD initiative. Two hundred and twenty agreed/strongly agreed (71.7%) that an element of their clinical practice had changed as a result of undertaking the BDJ CPD initiative. Journal based learning appears to be an effective way of undertaking verifiable CPD.

    The purpose of this DOE-funded effort is to develop continuous processes for solvent extraction of coal for the production of carbon products. These carbon products include materials used in metals smelting, especially in the aluminum and steel industries, as well as porous carbon structural material referred to as ''carbon foam'' and carbon fibers. There are a number of parameters which are important for the production of acceptable cokes, including purity, structure, density, electrical resistivity, thermal conductivity etc. From the standpoint of a manufacturer of graphite electrodes such as GrafTech, one of the most important parameters is coefficient of thermal expansion (CTE). Because GrafTech material is usually fully graphitized (i.e., heat treated at 3100 C), very high purity is automatically achieved. The degree of graphitization controls properties such as CTE, electrical resistivity, thermal conductivity, and density. Thus it is usually possible to correlate these properties using a single parameter. CTE has proven to be a useful index for the quality of coke. Pure graphite actually has a slightly negative coefficient of thermal expansion, whereas more disordered carbon has a positive coefficient.

    The purpose of this DOE-funded effort is to develop continuous processes for solvent extraction of coal for the production of carbon products. These carbon products include materials used in metals smelting, especially in the aluminum and steel industries, as well as porous carbon structural material referred to as ''carbon foam'' and carbon fibers. Table 1 provides an overview of the major markets for carbon products. Current sources of materials for these processes generally rely on petroleum distillation products or coal tar distillates obtained as a byproduct of metcoke production facilities. In the former case, the American materials industry, just as the energy industry, is dependent upon foreign sources of petroleum. In the latter case, metcoke production is decreasing every year due to the combined difficulties associated with poor economics and a significant environmental burden. Thus, a significant need exists for an environmentally clean process which can used domestically obtained raw materials and which can still be very competitive economically.

  19. Minimum detectable activity and false alarm rate relationships for alpha continuous air monitors

    1994-01-01

    The U.S. Department of Energy rule for Occupational Radiation Protection (10 CFR Part 835, December 1993) and the DOE Radiological Control Manual (the RCM) (DOE/EH-0256T, Rev. 1, April 1994) require the use of continuous air monitors (CAMs) in normally occupied areas where an individual is likely to be exposed to a concentration of airborne radioactivity exceeding the derived air concentration (DAC) or where there is a need to alert potentially exposed individuals to unexpected increases in airborne radioactivity levels. The DAC is the airborne concentration that equals the annual limit on intake divided by the volume of air breathed by an average worker for a working year of 2000 h (assuming a breathing volume of 2400 m 3 ). It is equivalent to the airborne concentration to which a worker could be exposed for an entire working year (2000 h) without exceeding the allowable annual limit on intake. The rule and the RCM further require that real-time air monitors have an alarm capability and sufficient sensitivity to alert potentially exposed individuals that immediate action is necessary in order to minimize or terminate inhalation exposures. The RCM also recommends that real-time air monitors should be capable of measuring 1 DAC when averaged over 8 h (8 DAC-h) under laboratory conditions. In response to these recommendations, we are developing procedures for determining the basic sensitivity of alpha CAMs under laboratory conditions and for documenting practical alarm set points for routine use of CAMs under a range of radon and thoron concentrations

    Observing a speaker's articulations substantially improves the intelligibility of spoken speech, especially under noisy listening conditions. This multisensory integration of speech inputs is crucial to effective communication. Appropriate development of this ability has major implications for children in classroom and social settings, and deficits in it have been linked to a number of neurodevelopmental disorders, especially autism. It is clear from structural imaging studies that there is a prolonged maturational course within regions of the perisylvian cortex that persists into late childhood, and these regions have been firmly established as being crucial to speech and language functions. Given this protracted maturational timeframe, we reasoned that multisensory speech processing might well show a similarly protracted developmental course. Previous work in adults has shown that audiovisual enhancement in word recognition is most apparent within a restricted range of signal-to-noise ratios (SNRs). Here, we investigated when these properties emerge during childhood by testing multisensory speech recognition abilities in typically developing children aged between 5 and 14 years, and comparing them with those of adults. By parametrically varying SNRs, we found that children benefited significantly less from observing visual articulations, displaying considerably less audiovisual enhancement. The findings suggest that improvement in the ability to recognize speech-in-noise and in audiovisual integration during speech perception continues quite late into the childhood years. The implication is that a considerable amount of multisensory learning remains to be achieved during the later schooling years, and that explicit efforts to accommodate this learning may well be warranted.

    Cleveland Clinic's continuous-flow total artificial heart has one motor and one rotating assembly supported by a hydrodynamic bearing. The right hydraulic output is self regulated by passive axial movement of the rotating assembly to balance itself with the left output. The purpose of this article is to present progress in four areas of development: the automatic speed control system, self-regulation to balance right/left inlet pressures and flows, hemolysis testing using calf blood, and coupled electromagnetics (EMAG) and computational fluid dynamics (CFD) analysis. The relationships between functions of motor power and speed, systemic flow, and systemic vascular resistance (SVR) were used for the sensorless speed control algorithm and demonstrated close correlations. Based on those empirical relationships, systemic flow and SVR were calculated in the system module and showed good correlation with measured pump flow and SVR. The automatic system adjusted the pump's speed to obtain the target flow in response to the calculated SVR. Atrial pressure difference (left minus right atrial pressure) was maintained within ±10 mm Hg for a wide range of SVR/pulmonary vascular resistance ratios, demonstrating a wide margin of self-regulation under fixed-speed mode and 25% sinusoidally modulated speed mode. Hemolysis test results indicated acceptable values (normalized index of hemolysis <0.01 mg/dL). The coupled EMAG/CFD model was validated for use in further device development. © 2012, Copyright the Authors.

    Undergraduate medical education (UME) programs are seeking systematic ways to monitor and manage their educational performance metrics and document their achievement of external goals (e.g., Liaison Committee on Medical Education [LCME] accreditation requirements) and internal objectives (institution-specific metrics). In other continuous quality improvement (CQI) settings, summary dashboard reports have been used to evaluate and improve performance. The Stony Brook University School of Medicine UME leadership team developed and implemented summary dashboard performance reports in 2009 to document LCME standards/criteria compliance, evaluate medical student performance, and identify progress in attaining institutional curricular goals and objectives. Key performance indicators (KPIs) and benchmarks were established and have been routinely monitored as part of the novel Drivers of Dashboard Development (3-D) approach to curricular CQI. The systematic 3-D approach has had positive CQI impacts. Substantial improvements over time have been documented in KPIs including timeliness of clerkship grades, midclerkship feedback, student mistreatment policy awareness, and student satisfaction. Stakeholder feedback indicates that the dashboards have provided useful information guiding data-driven curricular changes, such as integrating clinician-scientists as lecturers in basic science courses to clarify the clinical relevance of specific topics. Gaining stakeholder acceptance of the 3-D approach required clear communication of preestablished targets and annual meetings with department leaders and course/clerkship directors. The 3-D approach may be considered by UME programs as a template for providing faculty and leadership with a CQI framework to establish shared goals, document compliance, report accomplishments, enrich communications, facilitate decisions, and improve performance.

    How the human brain plans, executes, and monitors continuous and fluent speech has remained largely elusive. For example, previous research has defined the cortical locations most important for different aspects of speech function, but has not yet yielded a definition of the temporal progression of involvement of those locations as speech progresses either overtly or covertly. In this paper, we uncovered the spatio-temporal evolution of neuronal population-level activity related to continuous overt speech, and identified those locations that shared activity characteristics across overt and covert speech. Specifically, we asked subjects to repeat continuous sentences aloud or silently while we recorded electrical signals directly from the surface of the brain (electrocorticography (ECoG)). We then determined the relationship between cortical activity and speech output across different areas of cortex and at sub-second timescales. The results highlight a spatio-temporal progression of cortical involvement in the continuous speech process that initiates utterances in frontal-motor areas and ends with the monitoring of auditory feedback in superior temporal gyrus. Direct comparison of cortical activity related to overt versus covert conditions revealed a common network of brain regions involved in speech that may implement orthographic and phonological processing. Our results provide one of the first characterizations of the spatiotemporal electrophysiological representations of the continuous speech process, and also highlight the common neural substrate of overt and covert speech. These results thereby contribute to a refined understanding of speech functions in the human brain.

    The purpose of the present study was to develop and pilot test a questionnaire to assess continuity of care from the perspective of patients with diabetes. Seven patient and two healthcare-provider focus groups were conducted. These focus groups generated 777 potential items. This number was reduced to 56 items after item reduction, face validity testing and readability analysis, and to 47 items after a preliminary factor analysis. Readability was assessed as requiring 7-8 years of schooling. Sixty adult patients with diabetes completed the draft Diabetes Continuity of Care Scale (DCCS) at a single point in time to assess the validity of the instrument. Patients completed the draft DCCS again 2 weeks later to assess test-retest reliability. A provisional factor analysis and grouping according to clinical sense yielded five domains: access and getting care, care by doctor, care by other healthcare professionals, communication between healthcare professionals, and self-care. The internal consistency (Cronbach's alpha) for the whole scale was 0.89. The test-retest reliability was r = 0.73. The DCCS total score was moderately correlated with some of the measures used to establish construct validity. The DCCS could differentiate between patients who did and did not achieve specific process and clinical indicators of good diabetes care (e.g. Hba1c tested within 6 months). The development of the DCCS was centred on the patient's perspective and revealed that the patient perspective regarding continuity of care extends beyond the concept of seeing one doctor. Initial testing of this instrument demonstrates that it has promise as a reliable and valid measure in this area.

    Development of processes for leaching solid waste contaminated by alpha or alphaβgamma emitters has been pursued at the Nuclear Research Center in Fontenay-aux-Roses, France with the recent active commissioning of two pilot facilities: the Elise glove box system in February 1987 and the Prolixe shielded hot cell in March 1988. The Elise facility is designed to handle alpha waste and the Prolixe facility is designed to handle alphaβgamma waste. The common goal of the studies conducted in these facilities is to define the operating conditions for declassification of solid waste, i.e. to ensure that the alpha concentration of this waste will be less than 3.7 x 10 6 Bq/kg after treatment, packaging and decay prior to storage in surface repositories. The leaching process developed is mainly based on the continuous electrolytic regeneration of an aggressive agent, AgII, which can induce the dissolution of PuO 2 , the most difficult compound to remove from the solid waste. This paper summarizes recent achievements in the development of this process. 11 refs., 8 figs., 6 tabs

    The interest in continuing education (CE) for pharmacists has increased because of patient safety issues, advancing science and the quick changes in the profession. Therefore, contemporary pharmaceutical care requires an effective and sustainable system for pharmacists to maintain and improve competencies. Although motivation plays an important role both as a facilitator (desire to learn) and a barrier (lack of motivation), there is little investigated about this specific factor. The aim of the study was to explore what factors influence pharmacists' participation in CE with a focus on motivation. The theoretical framework was self-determination theory (SDT), which describes autonomous motivation (AM) representing motivation from an internal locus of causality, controlled motivation (CM) originating from an external locus of causality, and relative autonomous motivation (RAM) that measures the AM in an individual after correcting for the CM. The relationship between pharmacists' characteristics, especially their motivation (AM, CM and RAM) in CE, and their participation in CE activities was explored using the AMS-questionnaire and the Dutch online portfolio system. RAM was positively correlated with CE participation of pharmacists and explained 7.8% of the variance. The correlations between the independent variables AM and CM and CE hours were negative (-0.301 and -0.476, respectively). Other factors influencing CE participation were pharmacy school (6.8%), traineeship (10.9%), and work experience (7.8%). Pharmacists participated for 27.0 hours on average in CE during 11 months and preferred face-to-face-learning (85.5%) above e-learning (13.8%). Our findings show a positive relationship between RAM and CE participation. The current CE system is probably not conducive to stimulation of AM. Further research is needed to understand the factors that stimulate pharmacists' motivation and participation in CE.

    A near-infrared (NIR) calibration was developed using an efficient offline approach to enable a quantitative partial least-squares (PLS) chemometric model to measure and monitor the concentration of active pharmaceutical ingredients (API) in powder blends in the feed frame (FF) of a tablet press. The approach leveraged an offline "feed frame table," which was designed to mimic the full process from a NIR measurement perspective, thereby facilitating a more robust model by allowing more sources of variability to be included in the calibration by minimizing the consumption of API and other raw materials. The design of experiment (DOE) for the calibration was established by an initial risk assessment and included anticipated variability from factors related to formulation, process, environment, and instrumentation. A test set collected on the feed frame table was used to refine the PLS model. Additional fully independent test sets collected from the continuous drug product manufacturing process not only demonstrated the accuracy and precision of the model but also illustrated its robustness to material variability and process variability including mass flow rate and feed frame paddle speed. Further, it demonstrated that a calibration can be generated on the offline feed frame table and then successfully implemented on the full process equipment in a robust manner. Additional benefits of using the feed frame table include streamline model monitoring and maintenance activities in a manufacturing setting. The real-time monitoring enabled by this offline calibration approach can be useful as a key component of the control strategy for continuous manufacturing processes for drug products, including detecting special cause variations such as transient disturbances and enabling product collection/rejection based upon predetermined concentration limits, and may play an important role in enabling real-time release testing (RTRt) for manufactured pharmaceutical products.

    This document summarizes work being conducted under the U.S. Department of Energy's Office of Technology Development (EM-50) in support of the Tank Waste Remediation System (TWRS) Program. The specific work activities are organized by the following categories: safety, characterization, retrieval, barriers, pretreatment, low-level waste, and high-level waste. In most cases, the activities presented here were identified as supporting tank remediation by EM-50 integrated program or integrated demonstration lead staff and the selections were further refined by contractor staff. Data sheets were prepared from DOE-HQ guidance to the field issued in September 1993. Activities were included if a significant portion of the work described provides technology potentially needed by TWRS; consequently, not all parts of each description necessarily support tank remediation

    2002-01-01

    Surface-enhanced Raman scattering (SERS) is sensitive and selective and when coupled with fibre-optics could potentially produce an effective chemical sensing system. This thesis concerns the development of a single-fibre-based sensor, with an integral SERS-active substrate. A number of different methods for the manufacture of SERS-active surfaces on glass substrates were investigated and compared. The immobilisation of metal nanoparticles on glass functionalised with (3-aminopropyl)trimethoxysilane emerged as a suitable approach for the production of sensors. Substrates prepared by this approach were characterised using UV-visible spectroscopy, electron microscopy and Raman mapping. It was found that exposure of substrates to laser radiation led to a decrease in the signal recorded from adsorbed analytes. This speed of the decrease was shown to depend on the analyte, and the exciting wavelength and power. SERS-active fibre sensors were produced by immobilisation of silver nanoparticles at the distal end of a...

    This paper describes and discusses fifteen years (1999-2013) of continuous hourly atmospheric radon (222Rn) monitoring at the coastal low-altitude Southern Hemisphere Cape Point Station in South Africa. A strong seasonal cycle is evident in the observed radon concentrations, with maxima during the winter months, when air masses arriving at the Cape Point station from over the African continental surface are more frequently observed, and minima during the summer months, when an oceanic fetch is predominant. An atmospheric mean radon activity concentration of 676 ± 2 mBq/m3 is found over the 15-year record, having a strongly skewed distribution that exhibits a large number of events falling into a compact range of low values (corresponding to oceanic air masses), and a smaller number of events with high radon values spread over a wide range (corresponding to continental air masses). The mean radon concentration from continental air masses (1 004 ± 6 mBq/m3) is about two times higher compared to oceanic air masses (479 ± 3 mBq/m3). The number of atmospheric radon events observed is strongly dependent on the wind direction. A power spectral Fast Fourier Transform analysis of the 15-year radon time series reveals prominent peaks at semi-diurnal, diurnal and annual timescales. Two inter-annual radon periodicities have been established, the diurnal 0.98 ± 0.04 day-1 and half-diurnal 2.07 ± 0.15 day-1. The annual peak reflects major seasonal changes in the patterns of offshore versus onshore flow associated with regional/hemispheric circulation patterns, whereas the diurnal and semi-diurnal peaks together reflect the influence of local nocturnal radon build-up over land, and the interplay between mesoscale sea/land breezes. The winter-time diurnal radon concentration had a significant decrease of about 200 mBq/m3 (17%) while the summer-time diurnal radon concentration revealed nearly no changes. A slow decline in the higher radon percentiles (75th and 95th) for the

    Laboratory professionals are expected to maintain their knowledge on the most recent advances in laboratory testing and continuing professional development (CPD) programs can address this expectation. In developing countries, accessing CPD programs is a major challenge for laboratory personnel, partly due to their limited availability. An assessment was conducted among clinical laboratory workforce in Botswana to identify and prioritize CPD training needs as well as preferred modes of CPD delivery. A self-administered questionnaire was disseminated to medical laboratory scientists and technicians registered with the Botswana Health Professions Council. Questions were organized into domains of competency related to (i) quality management systems, (ii) technical competence, (iii) laboratory management, leadership, and coaching, and (iv) pathophysiology, data interpretation, and research. Participants were asked to rank their self-perceived training needs using a 3-point scale in order of importance (most, moderate, and least). Furthermore, participants were asked to select any three preferences for delivery formats for the CPD. Out of 350 questionnaires that were distributed, 275 were completed and returned giving an overall response rate of 79%. The most frequently selected topics for training in rank order according to key themes were (mean, range) (i) quality management systems, most important (79%, 74-84%); (ii) pathophysiology, data interpretation, and research (68%, 52-78%); (iii) technical competence (65%, 44-73%); and (iv) laboratory management, leadership, and coaching (60%, 37-77%). The top three topics selected by the participants were (i) quality systems essentials for medical laboratory, (ii) implementing a quality management system, and (iii) techniques to identify and control sources of error in laboratory procedures. The top three preferred CPD delivery modes, in rank order, were training workshops, hands-on workshops, and internet-based learning

  19. Development of analytically capable time-of-flight mass spectrometer with continuous ion introduction

    The present article describes the results and findings explored in the course of the development of the analytically capable prototype of continuous time-of-flight (CTOF) mass spectrometer. Currently marketed pulsed TOF (PTOF) instruments use ion introduction with a 10 ns or so pulse width, followed by a waiting period roughly 100 μs. Accordingly, the sample is under excitation in 10-4 part of the total measuring time. This very low duty cycle severely limits the sensitivity of the PTOF method. A possible approach to deal with this problem is to use linear sinusoidal dual modulation technique (CTOF) as described in this article. This way the sensitivity of the method is increased, due to the 50% duty cycle of the excitation. All other types of TOF spectrometer use secondary electron multiplier (SEM) for detection, which unfortunately discriminates in amplification in favor of the lighter ions. This discrimination effect is especially undesirable in a mass spectrometric method, which targets high mass range. In CTOF method, SEM is replaced with Faraday cup detector, thus eliminating the mass discrimination effect. Omitting SEM is made possible by the high ion intensity and the very slow ion detection with some hundred hertz detection bandwidth. The electrometer electronics of the Faraday cup detector operates with amplification 1010 V/A. The primary ion beam is highly monoenergetic due to the construction of the ion gun, which made possible to omit any electrostatic mirror configuration for bunching the ions. The measurement is controlled by a personal computer and the intelligent signal generator Type Tabor WW 2571, which uses the direct digital synthesis technique for making arbitrary wave forms. The data are collected by a Labjack interface board, and the fast Fourier transformation is performed by the software. Noble gas mixture has been used to test the analytical capabilities of the prototype setup. Measurement presented proves the results of the mathematical

    To assess the long-term sustainability of continuing professional development (CPD) training in pharmacy practice and learning behaviors. This was a 3-year posttrial survey of pharmacists who had participated in an unblinded randomized controlled trial of CPD. The online survey assessed participants' perceptions of pharmacy practice, learning behaviors, and sustainability of CPD. Differences between groups on the posttrial survey responses and changes from the trial's follow-up survey to the posttrial survey responses within the intervention group were compared. Of the 91 pharmacists who completed the original trial, 72 (79%) participated in the sustainability survey. Compared to control participants, a higher percentage of intervention participants reported in the sustainability survey that they had utilized the CPD concept (45.7% vs 8.1%) and identified personal learning objectives (68.6% vs 43.2%) during the previous year. Compared to their follow-up survey responses, lower percentages of intervention participants reported identifying personal learning objectives (94.3% vs 68.6%), documenting their learning plan (82.9% vs 22.9%) and participating in learning by doing (42.9% vs 14.3%) in the sustainability survey. In the intervention group, many of the improvements to pharmacy practice items were sustained over the 3-year period but were not significantly different from the control group. Sustainability of a CPD intervention over a 3-year varied. While CPD-trained pharmacists reported utilizing CPD concepts at a higher rate than control pharmacists, their CPD learning behaviors diminished over time.

    The increasingly more complex nature of hernia surgery means that training programs for young surgeons must now meet ever more stringent requirements. There is a growing demand for improved structuring and standardization of education and training in hernia surgery. In 2011, the concept of a Hernia School was developed in Germany and has been gradually implemented ever since. That concept comprises the following series of interrelated, tiered course elements: Hernie kompakt (Hernia compact), Hernie konkret (Hernia concrete), and Hernie complex (Hernia complex). All three course elements make provision for structured clinical training based on guest visits to approved hernia centers. The Hernia compact basic course imparts knowledge of anatomy working with fresh cadavers. Hernia surgery procedures can also be conducted using unfixed specimens. Knowledge of abdominal wall ultrasound diagnostics is also imparted and hernia surgery procedures simulated on pelvic trainers. In all three course elements, lectures are delivered by experts across the entire field of hernia surgery using evidence-based practices from the literature. To date, eight Hernie kompakt (Hernia compact) courses have been conducted, in each case with up to 55 participants, and with a total of 390 participants. On evaluating the course, over 95% of participants expressed the view that the Hernia compact course content improved hernia surgery training. Following that positive feedback, the more advanced Hernie konkret (Hernia concrete) and Hernie complex (Hernia complex) course elements were introduced in 2016. The experiences gained to date since the introduction of a Hernia School-a standardized curriculum concept for continuing training in hernia surgery-has been evaluated by participants as an improvement on hitherto hernia surgery training.

  2. Genetic and Environmental Continuity in Personality Development: A Meta-Analysis

    The longitudinal stability of personality is low in childhood, but increases substantially into adulthood. Theoretical explanations for this trend differ in the emphasis placed on intrinsic maturation and socializing influences. To what extent does the increasing stability of personality result from the continuity and crystallization of genetically influenced individual differences, and to what extent does the increasing stability of life experiences explain increases in personality trait stability? Behavioral genetic studies, which decompose longitudinal stability into sources associated with genetic and environmental variation, can help to address this question. We aggregated effect sizes from 24 longitudinal behavioral genetic studies containing information on a total of 21,057 sibling pairs from six types that varied in terms of genetic relatedness and ranged in age from infancy to old age. A combination of linear and nonlinear meta-analytic regression models were used to evaluate age-trends in levels of heritability and environmentality, stabilities of genetic and environmental effects, and the contributions of genetic and environmental effects to overall phenotypic stability. Both the genetic and environmental influences on personality increase in stability with age. The contribution of genetic effects to phenotypic stability is moderate in magnitude and relatively constant with age, in part because of small-to-moderate decreases in the heritability of personality over child development that offset increases in genetic stability. In contrast, the contribution of environmental effects to phenotypic stability increases from near-zero in early childhood to moderate in adulthood. The lifespan trend of increasing phenotypic stability, therefore, predominantly results from environmental mechanisms. PMID:24956122

    Prior interpersonal relationships and interactivity among members of professional associations may impact the learning process in continuing medical education (CME). On the other hand, CME programs that encourage interactivity between participants may impact structures and behaviors in these professional associations. With the advent of information and communication technologies, new communication spaces have emerged that have the potential to enhance networked learning in national and international professional associations and increase the effectiveness of CME for health professionals. In this article, network science, based on the application of network theory and other theories, is proposed as an approach to better understand the contribution networking and interactivity between health professionals in professional communities make to their learning and adoption of new practices over time. © 2015 The Alliance for Continuing Education in the Health Professions, the Society for Academic Continuing Medical Education, and the Council on Continuing Medical Education, Association for Hospital Medical Education.

    Full Text Available An efficient and easy-to-perform method was developed for immobilization of CaLB on mesoporous aminoalkyl polymer supports by bisepoxide activation. Polyacrylate resins (100–300 µm; ~50 nm pores with different aminoalkyl functional groups (ethylamine: EA and hexylamine: HA were modified with bisepoxides differing in the length, rigidity and hydrophobicity of the units linking the two epoxy functions. After immobilization, the different CaLB preparations were evaluated using the lipase-catalyzed kinetic resolution (KR of racemic 1-phenylethanol (rac-1 in batch mode and in a continuous-flow reactor as well. Catalytic activity, enantiomer selectivity, recyclability, and the mechanical and long-term stability of CaLB immobilized on the various supports were tested. The most active CaLB preparation (on HA-resin activated with 1,6-hexanediol diglycidyl ether—HDGE retained 90% of its initial activity after 13 consecutive reaction cycles or after 12 month of storage at 4 °C. The specific rate (rflow, enantiomer selectivity (E and enantiomeric excess (ee achievable with the best immobilized CaLB preparations were studied as a function of temperature in kinetic resolution of rac-1 performed in continuous-flow packed-bed bioreactors. The optimum temperature of the most active HA-HDGE CaLB in continuous-flow mode was 60 °C. Although CaLB immobilized on the glycerol diglycidyl ether (GDGE-activated EA-resin was less active and less selective, a much higher optimum temperature (80 °C was observed with this form in continuous-flow mode KR of rac-1.

    Energy Technology Data Exchange (ETDEWEB)

    Doroodian, Amir

    2010-12-03

    This dissertation is divided into three chapters. Recently, metal-free hydrogen activation using phosphorous compounds has been reported in science magazine. We have investigated the interaction between hydrogen and phosphorous compounds in presence of strong Lewis acids (chapter one). A new generation of metal-free hydrogen activation, using amines and strong Lewis acids with sterically demanding nature, was already developed in our group. Shortage of high storage capacity using large substitution to improve sterical effect led us to explore the amine borane derivatives, which are explained in chapter two. Due to the high storage capacity of hydrogen in aminoborane derivatives, we have explored these materials to extend hydrogen release. These compounds store hydrogen as proton and hydride on adjacent atoms or ions. These investigations resulted in developing hydrogen storage based on ionic liquids containing methyl guanidinium cation. Then we have continued to develop ionic liquids based on methyl guanidinium cation with different anions, such as tetrafluoro borate (chapter three). We have replaced these anions with transition metal anions to investigate hydrogen bonding and catalytic activity of ionic liquids. This chapter illustrates the world of ionic liquid as a green solvent for organic, inorganic and catalytic reactions and combines the concept of catalysts and solvents based on ionic liquids. The catalytic activity is investigated particularly with respect to the interaction with CO{sub 2}. (orig.)

  10. Robust Finite-Time Stabilization of Fractional-Order Neural Networks With Discontinuous and Continuous Activation Functions Under Uncertainty.

    This paper is concerned with robust finite-time stabilization for a class of fractional-order neural networks (FNNs) with two types of activation functions (i.e., discontinuous and continuous activation function) under uncertainty. It is worth noting that there exist few results about FNNs with discontinuous activation functions, which is mainly because classical solutions and theories of differential equations cannot be applied in this case. Especially, there is no relevant finite-time stabilization research for such system, and this paper makes up for the gap. The existence of global solution under the framework of Filippov for such system is guaranteed by limiting discontinuous activation functions. According to set-valued analysis and Kakutani's fixed point theorem, we obtain the existence of equilibrium point. In particular, based on differential inclusion theory and fractional Lyapunov stability theory, several new sufficient conditions are given to ensure finite-time stabilization via a novel discontinuous controller, and the upper bound of the settling time for stabilization is estimated. In addition, we analyze the finite-time stabilization of FNNs with Lipschitz-continuous activation functions under uncertainty. The results of this paper improve corresponding ones of integer-order neural networks with discontinuous and continuous activation functions. Finally, three numerical examples are given to show the effectiveness of the theoretical results.

    Active Pharmaceutical Ingredients (API) raw material variability is not always thoroughly considered during pharmaceutical process development, mainly due to low quantities of drug substance available. However, synthesis, crystallization routes and production sites evolve during product development and product life cycle leading to changes in physical material attributes which can potentially affect their processability. Recent literature highlights the need for a global approach to understand the link between material synthesis, material variability, process and product quality. The study described in this article aims at explaining the raw material variability of an API using extensive material characterization on a restricted number of representative batches using multivariate data analysis. It is part of a larger investigation trying to link the API drug substance manufacturing process, the resulting physical API raw material attributes and the drug product continuous manufacturing process. Eight API batches produced using different synthetic routes, crystallization, drying, delumping processes and processing equipment were characterized, extensively. Seventeen properties from seven characterization techniques were retained for further analysis using Principal Component Analysis (PCA). Three principal components (PCs) were sufficient to explain 92.9 % of the API raw material variability. The first PC was related to crystal length, agglomerate size and fraction, flowability and electrostatic charging. The second PC was driven by the span of the particle size distribution and the agglomerates strength. The third PC was related to surface energy. Additionally, the PCA allowed to summarize the API batch-to-batch variability in only three PCs which can be used in future drug product development studies to quantitatively evaluate the impact of the API raw material variability upon the drug product process. The approach described in this article could be applied to

  14. Vitamin D: considerations in the continued development as an agent for cancer prevention and therapy.

    Trump, Donald L; Deeb, Kristin K; Johnson, Candace S

    2010-01-01

    Considerable preclinical and epidemiologic data suggest that vitamin D may play a role in the pathogenesis, progression, and therapy for cancer. Numerous epidemiologic studies support the hypothesis that individuals with lower serum vitamin D levels have a higher risk of a number of cancers. Measures of vitamin D level in such studies include both surrogate estimates of vitamin D level (residence in more northern latitudes, history of activity, and sun exposure) as well as measured serum 25(OH) cholecalciferol levels. Perhaps, the most robust of these epidemiologic studies is that of Giovannucci et al, who developed and validated an estimate of serum 25(OH) cholecalciferol level and reported that among >40,000 individuals in the Health Professionals Study, an increase in 25(OH) cholecalciferol level of 62.5 ng/mL was associated with a reduction in the risk of head/neck, esophagus, pancreas cancers, and acute leukemia by >50%. Unfortunately, very limited data are available to indicate whether or not giving vitamin D supplements reduces the risk of cancer. Many preclinical studies indicate that exposing cancer cells, as well as vascular endothelial cells derived from tumors, to high concentrations of active metabolites of vitamin D halts progression through cell cycle, induces apoptosis and will slow or stop the growth of tumors in vivo. There are no data that one type of cancer is more or less susceptible to the effects of vitamin D. Vitamin D also potentiates the antitumor activity of a number of types of cytotoxic anticancer agents in in vivo preclinical models. Vitamin D analogues initiate signaling through a number of important pathways, but the pathway(s) essential to the antitumor activities of vitamin D are unclear. Clinical studies of vitamin D as an antitumor agent have been hampered by the lack of a suitable pharmaceutical preparation for clinical study. All commercially available formulations are inadequate because of the necessity to administer large

    Implant dentistry is a treatment modality which has mainstream clinical practice of comprehensive care, which however is not adequately represented in the undergraduate dental curricula. A consensus workshop organised by ADEE in 2008, set the benchmarks for the knowledge and competences a modern dental practitioner must possess with regard to implant dentistry, as well as defined undergraduate and postgraduate pathways for the acquisition of these competences. Today, 5 years later, there exist several challenges for the implementation of these benchmarks in both undergraduate curricula but also post-graduation educational pathways. A consensus workshop was organised by ADEE, bringing together 48 opinion leaders, including academic teachers of all disciplines related to implant dentistry, specialists, representatives of relevant scientific and professional associations, as well as industry delegates. The objectives of the workshop were to evaluate the existing scientific literature, reported experience and best practices in order to identify potential and limitations for the implementation of implant dentistry in the undergraduate curriculum, as well produce recommendations for the optimal educational structures for postgraduate programmes and continuing professional development. The scientific committee conducted two European-wide questionnaire surveys to better document the current state of education in implant dentistry. Upon completion of the surveys, reviewers were appointed to produce three scientific review papers, identifying current achievements and future challenges. Finally, during the 3 days of the workshop, all the evidence was reviewed and the main conclusions and recommendations that were adopted by all participants are reported in the present Consensus Paper. Implementation of implant dentistry in the undergraduate curriculum has improved significantly, but still lags behind the benchmarks set in 2008 and the diversity between institutions remains

    Decision-makers in organizations providing continuing professional development (CPD) have identified the need for routine assessment of its impact on practice. We sought to develop a theory-based instrument for evaluating the impact of CPD activities on health professionals' clinical behavioral intentions. Our multipronged study had four phases. 1) We systematically reviewed the literature for instruments that used socio-cognitive theories to assess healthcare professionals' clinically-oriented behavioral intentions and/or behaviors; we extracted items relating to the theoretical constructs of an integrated model of healthcare professionals' behaviors and removed duplicates. 2) A committee of researchers and CPD decision-makers selected a pool of items relevant to CPD. 3) An international group of experts (n = 70) reached consensus on the most relevant items using electronic Delphi surveys. 4) We created a preliminary instrument with the items found most relevant and assessed its factorial validity, internal consistency and reliability (weighted kappa) over a two-week period among 138 physicians attending a CPD activity. Out of 72 potentially relevant instruments, 47 were analyzed. Of the 1218 items extracted from these, 16% were discarded as improperly phrased and 70% discarded as duplicates. Mapping the remaining items onto the constructs of the integrated model of healthcare professionals' behaviors yielded a minimum of 18 and a maximum of 275 items per construct. The partnership committee retained 61 items covering all seven constructs. Two iterations of the Delphi process produced consensus on a provisional 40-item questionnaire. Exploratory factorial analysis following test-retest resulted in a 12-item questionnaire. Cronbach's coefficients for the constructs varied from 0.77 to 0.85. A 12-item theory-based instrument for assessing the impact of CPD activities on health professionals' clinical behavioral intentions showed adequate validity and reliability

    Participation in continuing professional development (CPD) is a professional and regulatory expectation of general practitioners (GPs). Traditionally, CPD activity was undertaken face-to-face in educational settings, but internet based formats have found increasing favour. The need for doctors to use the internet for service and educational purposes is growing, particularly in support of specialty training and appraisal. We aimed to determine how GPs in Scotland utilise online resources in support of their CPD. This involved identifying which resources are used and how frequently, along with their preferences as to how and why they access these resources. A cross sectional study was undertaken using an online questionnaire to survey general practitioners across Scotland. Data were subjected to descriptive analysis and differences in attitudinal responses between groups and Fischer's exact tests were calculated. Three hundred and eighty-three GP responses were received, with the majority being female (n = 232, 60.6%) and GP partners (n = 236, 61.6%). The majority used the internet on three or more working days per week or more frequently (n = 361, 94.3%) with the three most common reasons being to obtain information for a patient (n = 358, 93.5%), answering a clinical question (n = 357, 93.2%) and CPD purposes (n = 308, 80.4%). Of 37 online resources used by respondents, the top five were SIGN Guidelines (n = 303, 79.3%), BMJ Learning (n = 279, 73.0%), NICE Guidelines (n = 255, 66.8%), GP Notebook (n = 243, 63.6%) and Google (n = 234, 61.3%). Low use of social media such as Facebook (n = 11, 2.9%) and Twitter (n = 11, 2.9%) was reported for CPD. A majority agreed that 'reading information online' (95.0%) and 'completing online learning modules' (87.4%) were the most valued online activities. Slow internet connections (n = 240, 62.7%), website access restrictions (n = 177, 46.2%) and difficulties logging

    The cyclotron has an obvious advantage in offering high average current and beam power. Cyclotron development for various applications, e.g. radioactive ion-beam (RIB) generation, clean nuclear energy systems, medical diagnostics and isotope production, were performed at China Institute of Atomic Energy (CIAE) for over 50 years. At the moment two cyclotrons are being built at CIAE, the 100 MeV, CYCIAE-100, and a 14 MeV, the CYCIAE-14. Meanwhile, we are designing and proposing to build a number of cyclotrons with different energies, among them are the CYCIAE-70, the CYCIAE-800, and the upgrading of CYCIAE-CRM, which is going to increase its beam current to mA level. The contribution will present an overall introduction to the cyclotron development activities conducted at CIAE, with different emphasis to each project in order to demonstrate the design and construction highlights.

    The method for producing AgNPs by granules of activated sludge micromycetes with enhanced tolerance to metal ion toxicity - Penicillium glabrum, Fusarium nivale and Fusarium oxysporum has been developed; the optimum conditions for AgNP biosynthesis being found: the Ag + ion concentration, duration of the contact of microbial cells with silver ions, a growth phase of microorganisms, medium composition, a рН value, mixing conditions, and also lighting intensity. The effect of Cl - , SO 4 2- and HPO 4 2- ions binding Ag + ions was eliminated, that brought to significant increase of the yield of NPs. Under batch conditions, silver particles of 60-110 nanometers in size were formed with a 65% yield. It was established that the nanoparticles were covered with microbial cell membrane proteins composed up to 70% by weight of the NPs that prevented their aggregation. In addition, it was the first time stable AgNPs had been formed by continuous AgNP biosynthesis by living cells of F. oxysporum with an 80% yield for a long time. Copyright © 2016 Elsevier Inc.

    The FLuorescence Imaging Spectrometer (FLORIS) is the payload of the FLuorescence Explorer Mission (FLEX) of the European Space Agency. The mission objective is to perform quantitative measurements of the solar induced vegetation fluorescence to monitor photosynthetic activity. FLORIS works in a push-broom configuration and it is designed to acquire data in the 500-780 nm spectral range, with a sampling of 0.1 nm in the oxygen bands (759-769 nm and 686- 697 nm) and 0.5-2.0 nm in the red edge, chlorophyll absorption and Photochemical Reflectance Index bands. FLEX will fly in formation with Sentinel-3 to benefit of the measurements made by the Sentinel-3 instruments OLCI and SLSTR, particularly for cloud screening, proper characterization of the atmospheric state and determination of the surface temperature. The instrument concept is based on a common telescope and two modified Offner spectrometers with reflective concave gratings both for the High Resolution (HR) and Low Resolution (LR) spectrometers. In the frame of the instrument pre-development Leonardo Company (I) has built and tested an elegant breadboard of the instrument consisting of the telescope and the HR spectrometer. The development of the LR spectrometer is in charge of OHB System AG (D) and is currently in the manufacturing phase. The main objectives of the activity are: anticipate the development of the instrument and provide early risk retirement of critical components, evaluate the system performances such as imaging quality parameters, straylight, ghost, polarization sensitivity and environmental influences, verify the adequacy of critical tests such as spectral characterization and straylight, define and optimize instrument alignment procedures. Following a brief overview of the FLEX mission, the paper will cover the design and the development of the optics breadboard with emphasis on the results obtained during the tests and the lessons learned for the flight unit.

  8. Design, development and characterization of microfluidic media for continuous size-based separation of particles

    Devendra, Raghavendra

    Microfluidics is a growing field of research in separations. Microfluidic technologies offer a greater control over system properties with an efficient performance while providing a potential for integration of several processes into one micro-total-analysis system. While several conventional separation technologies have been miniaturized to micro-scale techniques, there is an effort to develop novel processes that take advantage of the features of micro-scale flows, such as similarities in pore-species dimensions and the ability to tailor the geometric structures of the stationary phase to specific applications. In certain cases, the geometric structure of the pore space drives the separative displacement; the advances in microfabrication allow greater control over the geometry as well as the surface chemistry of the media. It is convenient and possible to integrate the microstructure into main separation channel and design autonomous continuous flow separation systems on a lab-on-achip platform. A promising approach to develop passive and continuous flow microfluidic separation devices is to design periodic arrays of obstacles that cause different species to move in different directions within the device, also known as vector chromatography. The principle of separation of small particles in such periodic microstructures is based on the mobility of particles. The mobility of a particle is based on its size, the geometry of the stationary phase and the viscosity of the suspending phase. In the first part of this thesis, we present a study of diffusive transport in periodic anisotropic systems. We designed and fabricated anisotropic periodicities in microfluidic devices and characterized the mobilities in principal directions by directly measuring the one dimensional diffusivities through experiments. In anisotropic periodic microstructures, the mobility has unequal components, by virtue of which the velocity of the particle does not remain collinear with the

    Neutron activation analysis (NAA) is a powerful isotope specific nuclear analytical technique for simultaneous determination of major to trace elemental concentrations in diverse matrices. NAA is associated with high analytical sensitivities and low detection limits (ppm to ppb) due to utilization of high neutron flux from research reactors and high efficiency high resolution gamma ray spectrometry. Elemental concentrations are determined either by conventional NAA using relative method or by single comparator method of NAA (k 0 -NAA). Since 1994, Radiochemistry Division is actively engaged in developments and applications of k 0 -based NAA and Prompt Gamma ray NAA (PGNAA) methods for compositional characterization of materials, in addition to conventional instrumental NAA (INAA) and chemical NAA (CNAA) methods for total as well as speciation studies. The article briefly summarizes developments of k 0 based method of NAA using an external single comparator (k 0 -NAA) and an internal monostandard (lM-NAA) and PGNAA and their applications to small as well as large size samples. The article also briefly highlights the application of INAA and chemical NAA (CNAA) for speciation studies of arsenic and iodine in environmental and food samples respectively and bioaccesibility of selenium in food samples and trace elements wheatgrass samples

    Significantly improved performance during electrochemical testing of a cell with a dense continuous pulsed laser deposited (PLD) samarium doped ceria (SDC) layer spurred investigations into the fabrication of dense continuous SDC barrier layers by means of cost-effective deposition using screen printing which is amenable to industrial production of SOFCs. Many approaches to improve the SDC density have been explored including the use of powder with reduced particle sizes, inks with increased solids loading, and doping with sintering aids (1). In terms of sintering aids, dopants like Mo or binary systems of Mo+Cu or Fe+Co greatly enhance SDC sinterability. In fact, adding dopants to a screen printed, prefired, porous SDC layer made it possible to achieve a dense continuous barrier layer atop the YSZ electrolyte without sintering above 1200°C. Although the objective of fabricating a dense continuous layer was achieved, additional studies have been initiated to improve the cell performance. Underlying issues with constrained sintering and dopant-enhanced ceria-zirconia solid solubility are also addressed in this paper.

    2017-01-01

    Purpose: This study aimed to identify current barriers to CPD and generate ideas for strategies to overcome these issues. Further aims were to gather an overview of respondents' understanding and opinions of CPD. Methods: An online survey was used to acquire information from departmental band 5 and band 6 radiographers. Descriptive statistical analysis and thematic analysis were performed to understand demographics and individuals' behaviours and experiences. Findings: Radiographers (n = 33) were sent an invitation via email providing a response rate of 75.8% (n = 25), with 20 females (80%) and 5 males (20%). 52% (n = 13) dedicate less than three hours a month. Participants highlighted time restraint as their biggest barrier to CPD. They also indicated a reluctance to use their own time to undertake work-related learning, despite exhibiting positive attitudes towards CPD. Radiographers see CPD as a vital and necessary, career-long learning process and they recognise the impacts on service provision. The notion of dedicated study time was unanimously suggested as the best approach to increase commitment to CPD. Conclusion: Radiographers demonstrated positive opinions of CPD, yet it was evident that many are not undertaking activities during their own time and it was acknowledged that opportunities during work time are limited. The provision of study time in work was suggested as an approach to improve radiographer's opportunities to complete CPD. Training sessions underlining the necessity of CPD in maintaining registration, what constitutes CPD and reinforcement of the benefits of systematic recording of CPD should be provided. - Highlights: • 80% believe they do not do enough CPD, 52% dedicate less than 3 h a month. • Radiographers are aware of the positive impact of learning on development. • Training should be given as a strategy to address radiographers' CPD inactivity. • The overarching theme relating to barriers to CPD is

    To describe professionals' perceptions of factors that facilitate or hamper the implementation and continuation of a physical activity promotion programme in rehabilitation. This study used a qualitative design. Semi-structured interviews (n = 22) were conducted with rehabilitation professionals (n = 28) involved in the implementation of a physical activity promotion programme. Two additional interviews were conducted with the programme coordinators (n = 2). The study involved 18 rehabilitation organizations implementing the programme that targets people with disabilities or chronic diseases. Organizations were supported in the implementation process by the programme coordinators. Commonly perceived facilitating factors were: involvement of committed and enthusiastic professionals; agreement with their organizations' vision/wishes; the perceived additional value of the programme; and opportunities to share knowledge and experience with professionals from other organizations. Commonly perceived hampering factors were: uncertainty about continuing the programme; limited flexibility; and lack of support from physicians and therapists to implement the programme. Professionals perceived a heterogeneous set of factors that facilitate and/or hamper the implementation and continuation of a physical activity promotion programme in rehabilitation. Based on these findings, recommendations were formulated to enhance embedding of physical activity promotion during and after rehabilitation.

    There is a need for a transformational change in clinical education. In postgraduate medical education we have traditionally had a faculty-centric model. That is, faculty knew what needed to be taught and who were the best teachers to teach it. They built the agenda, and worked with staff to follow Accreditation Council for Continuing Medical Education (ACCME) accreditation criteria and manage logistics. Changes in the health care marketplace now demand a learner-centric model-one that embraces needs assessments, identification of practice gaps relative to competency, development of learning objectives, contemporary adult learning theory, novel delivery systems, and measurable outcomes. This article provides a case study of one medical specialty society's efforts to respond to this demand. © 2015 The Alliance for Continuing Education in the Health Professions, the Society for Academic Continuing Medical Education, and the Council on Continuing Medical Education, Association for Hospital Medical Education.

    The combination of molecular exclusion chromatography and laser polarimetric detection has turned into a carbohydrate separation and quantification system for plant fluids of industrial value, making it possible the evaluation of the quality of sugarcane juices, agave juices and many other plant extracts. Some previous papers described a system where liquid chromatography separation and polarimetric detection using a LASERPOL 101M polarimeter with He-Ne light source allowed the collection and quantification of discrete samples for analytical purposes. In this paper, the authors are introducing a new improved system which accomplishes polarimetric measurements in a continuous flux. Chromatograms of several carbohydrates standard solutions were obtained as useful references to study juice quality of several sugarcane varieties under different physiological conditions. Results by either discrete or continuous flux systems were compared in order to test the validation of the new system. An application of the system to the diagnostics of scalded foliar is described. A computer program allowing the output of the chromatograms to a display on line and the possibility of digital storing, maxima detections, zone integration, and some other possibilities make this system very competitive and self-convincing.

    In the past few years, continuous-flow reactors with channel dimensions in the micro- or millimeter region have found widespread application in organic synthesis. The characteristic properties of these reactors are their exceptionally fast heat and mass transfer. In microstructured devices of this type, virtually instantaneous mixing can be achieved for all but the fastest reactions. Similarly, the accumulation of heat, formation of hot spots, and dangers of thermal runaways can be prevented. As a result of the small reactor volumes, the overall safety of the process is significantly improved, even when harsh reaction conditions are used. Thus, microreactor technology offers a unique way to perform ultrafast, exothermic reactions, and allows the execution of reactions which proceed via highly unstable or even explosive intermediates. This Review discusses recent literature examples of continuous-flow organic synthesis where hazardous reactions or extreme process windows have been employed, with a focus on applications of relevance to the preparation of pharmaceuticals. © 2015 WILEY-VCH Verlag GmbH & Co.

  5. Small, Continual Lightning Activity in the Overshooting Turret of Supercell Storms

    Several supercell storms have occurred within the region in which the Oklahoma Lightning Mapping Array (OKLMA) maps all three spatial dimensions of lightning. These storms span much of the supercell spectrum -- from non-tornadic storms to storms that produced strong tornadoes and from low-precipitation to heavy- precipitation morphologies. As noted by several studies, supercell storms tend to have much larger flash rates than ordinary isolated thunderstorms; maximum rates are typically hundreds of flashes per minute, even when considering only flashes that produce at least ten mapped points per flash. However, the OKLMA indicates that most of the flashes occurring within the main body of the storm during periods of high flash rates have quite small spatial extents, many with a long dimension of 3-10 km. Not usually included in these flash rates are a large number that appear to be isolated points (sometimes called singletons), each failing criteria of distance or time for associating it with other points in a flash. Often determining whether these isolated points are artifacts of the OKLMA is difficult, but in the overshooting top, they present a coherent pattern that appears plausible. They are distributed throughout a cap having horizontal dimensions comparable to that of the overshooting top and sitting near or on the upper surface. They occur continually, though they are too far apart in time or space to be associated in a flash with each other. A comparison with high-resolution reflectivity data for one storm observed by the two mobile 5-cm wavelength SMART-R radars shows that these isolated points were most concentrated near the top of the 40 dBZ echo in the overshooting turret, but some occurred higher, in regions of small reflectivity or just above the overshooting top. These points may be similar to the continual lightning noted by Bill Taylor in the upper region of a severe storm in the early 1980s.

    Initially, human area MT+ was considered a visual area solely processing motion information but further research has shown that it is also involved in various different cognitive operations, such as working memory tasks requiring motion-related information to be maintained or cognitive tasks with implied or expected motion.In the present fMRI study in humans, we focused on MT+ modulation during working memory maintenance using a dynamic shape-tracking working memory task with no motion-related working memory content. Working memory load was systematically varied using complex and simple stimulus material and parametrically increasing retention periods. Activation patterns for the difference between retention of complex and simple memorized stimuli were examined in order to preclude that the reported effects are caused by differences in retrieval. Conjunction analysis over all delay durations for the maintenance of complex versus simple stimuli demonstrated a wide-spread activation pattern. Percent signal change (PSC) in area MT+ revealed a pattern with higher values for the maintenance of complex shapes compared to the retention of a simple circle and with higher values for increasing delay durations. The present data extend previous knowledge by demonstrating that visual area MT+ presents a brain activity pattern usually found in brain regions that are actively involved in working memory maintenance.

  9. Development of a new adaptive ordinal approach to continuous-variable probabilistic optimization.

    Energy Technology Data Exchange (ETDEWEB)

    2006-11-01

    A very general and robust approach to solving continuous-variable optimization problems involving uncertainty in the objective function is through the use of ordinal optimization. At each step in the optimization problem, improvement is based only on a relative ranking of the uncertainty effects on local design alternatives, rather than on precise quantification of the effects. One simply asks ''Is that alternative better or worse than this one?'' -not ''HOW MUCH better or worse is that alternative to this one?'' The answer to the latter question requires precise characterization of the uncertainty--with the corresponding sampling/integration expense for precise resolution. However, in this report we demonstrate correct decision-making in a continuous-variable probabilistic optimization problem despite extreme vagueness in the statistical characterization of the design options. We present a new adaptive ordinal method for probabilistic optimization in which the trade-off between computational expense and vagueness in the uncertainty characterization can be conveniently managed in various phases of the optimization problem to make cost-effective stepping decisions in the design space. Spatial correlation of uncertainty in the continuous-variable design space is exploited to dramatically increase method efficiency. Under many circumstances the method appears to have favorable robustness and cost-scaling properties relative to other probabilistic optimization methods, and uniquely has mechanisms for quantifying and controlling error likelihood in design-space stepping decisions. The method is asymptotically convergent to the true probabilistic optimum, so could be useful as a reference standard against which the efficiency and robustness of other methods can be compared--analogous to the role that Monte Carlo simulation plays in uncertainty propagation.

    Objectives: We examined the changes in waking electroencephalography (EEG) biomarkers with modafinil during continuous positive airway pressure (CPAP) withdrawal in patients with obstructive sleep apnea (OSA) to investigate neurophysiological evidence for potential neurocognitive improvements. Design: Randomized double-blind placebo-controlled crossover study. CPAP was used for the first night and then withdrawn for 2 subsequent nights. Each morning after the 2 CPAP withdrawal nights, patients received either 200 mg modafinil or placebo. After a 5-w washout, the procedure repeated with the crossover drug. Setting: University teaching hospital. Participants: Stable CPAP users (n = 23 men with OSA) Measurement and Results: Karolinska Drowsiness Test (KDT) (awake EEG measurement with eyes open and closed), Psychomotor Vigilance Task (PVT), and driving simulator Performance were assessed bihourly during the 3 testing days following CPAP treatment and CPAP withdrawal nights. Compared to placebo, modafinil significantly increased awake EEG activation (faster EEG frequency) with increased alpha/delta (A/D) ratio (P Modafinil administration during continuous positive airway pressure (CPAP) withdrawal increased awake EEG activation, which correlated to improved performance. This study provides supporting neurophysiological evidence that modafinil is a potential short-term treatment option during acute CPAP withdrawal.

  19. Writing Games: Continuity and Change in the Design and Development of Quiz Shows in Italy

    2013-12-01

    Full Text Available As in the United States and in many countries across Europe, the quiz show was a founding genre for Italian television as far back as the 1950s: because of their broad appeal, such game shows as Lascia o raddoppia and Il musichiere contributed strongly to television’s burgeoning popularity during the subsequent decades. Since then, the quiz show has traversed different eras of television history, with partial and gradual changes to its textual features, aesthetics and narratives, as well as its production routines. Since the 1980s, with deregulation and the advent of commercial television, the Italian game-show market has become more international and more reliant on formats. In the genre’s long history, the “hidden profession” of writing TV games exhibits elements of both continuity and change. The needs of format-adaptation have highlighted two main areas of “localization”: question-writing and casting. This essay explores the profession of game-show writer in Italy and how the role has evolved. It adopts a historical framework to illuminate the continuity and change in the profession, in relation to a broader history of both the genre and the television medium, while also seeking to outline both the specificity of the Italian TV context and its connections with an international environment.

    A continuous fast microwave-assisted pyrolysis system was designed, fabricated, and tested with sewage sludge. The system is equipped with continuous biomass feeding, mixing of biomass and microwave absorbent, and separated catalyst upgrading. The effect of the sludge pyrolysis temperature (450, 500, 550, and 600 °C) on the products yield, distribution and potentially energy recovery were investigated. The physical, chemical, and energetic properties of the raw sewage sludge and bio-oil, char and gas products obtained were analyzed using elemental analyzer, GC-MS, Micro-GC, SEM and ICP-OES. While the maximum bio-oil yield of 41.39 wt% was obtained at pyrolysis temperature of 550 °C, the optimal pyrolysis temperature for maximum overall energy recovery was 500 °C. The absence of carrier gas in the process may be responsible for the high HHV of gas products. This work could provide technical support for microwave-assisted system scale-up and sewage sludge utilization. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Mordenite minerals derived from Sukabumi natural green stone founded in Indonesia was tested in order to remove iron and manganese from natural groundwater. This research used two types of adsorbents which were consisted of physically activated and natural mordenite. Physical activation of the mordenite was carried out by heating at 400-600°C for two hours. Batch system experiments was also conducted as a preliminary experiment. Batch system proved that both activated and natural mordenite minerals were capable of reducing iron and manganese concentration from natural groundwater. Then, continuous experiment was conducted using down-flow system with 45 ml/minute of constant flow rate. The iron & manganese removal efficiency using continuous reactor for physically activated and natural mordenite were 1.38-1.99%/minute & 0.8-1.49%/minute and 2.26%/minute & 1.37-2.26%/minute respectively. In addition, the regeneration treatment using NH4Cl solution managed to improve the removal efficiency of iron & manganese to 1.98%/minute & 1.77-1.90%/minute and 2.25%/minute & 2.02-2.21%/minute on physically activated mordenite and natural mordenite respectively. Subsequently, the activation of the new mordenite was carried out by immersing mordenite in NH4Cl solution. This chemical activation showed 2.42-2.75%/minute & 0.96 - 2.67 %/minute and 2.66 - 2.78 %/minute & 1.34 - 2.32 %/minute of iron & manganese removal efficiency per detention time for chemically activated and natural mordenite respectively.

    There is a lack of standardized mobility measures specific to the long-term care (LTC) population. Therefore, the Continuing Care Activity Measure (CCAM) was developed. This study determined levels of reliability, validity for clinical utilization, and sensitivity to change of this measure. This was a prospective longitudinal cohort study among elderly people with primarily physical or medical impairments who were residing in LTC institutions that provide nursing home and more-complex care, with access to physical therapy services. The CCAM, the Clinical Outcome Variables Scale (COVS), the Social Engagement Scale (SES) of the Resident Assessment Instrument-Minimum Data Set (RAI-MDS) 2.0 instrument, and the Resource Utilization Groups, version 3, (RUG-III) were administered by clinical and research physical therapists, with timing dictated by the study purpose. The participants were 136 residents of LTC institutions and 21 physical therapists. The CCAM interrater reliability (intraclass correlation coefficient [ICC]) was .97 (95% confidence interval=.91-1.00), and test-retest reliability (ICC) over a period of 1 week was .99 (95% confidence interval=.93-1.00). Over 6 months, the absolute change in total score was 5.88 for the CCAM and 4.26 for the COVS; the CCAM was 28% more responsive across all participants (n=105) and 68% more responsive for those scoring in the lower half (n=49). The minimal detectable difference of the CCAM was 8.6 across all participants. The CCAM correlated with the COVS, nursing care hours inferred from the RUG-III, and the SES. Some participants were lost to follow-up. The CCAM is a reliable and valid tool to measure gross motor function and physical mobility for elderly people in LTC institutions. It discriminates among functional levels, measures individual functional change, and can contribute to clinical decision making.

  3. Analysis and active compensation of microphonics in continuous wave narrow-bandwidth superconducting cavities

    Directory of Open Access Journals (Sweden)

    A. Neumann

    2010-08-01

    Full Text Available Many proposals for next generation light sources based on single pass free electron lasers or energy recovery linac facilities require a continuous wave (cw driven superconducting linac. The effective beam loading in such machines is very small and in principle the cavities can be operated at a bandwidth of a few Hz and with less than a few kW of rf power. However, a power reserve is required to ensure field stability. A major error source is the mechanical microphonics detuning of the niobium cavities. To understand the influence of cavity detuning on longitudinal beam stability, a measurement program has been started at the horizontal cavity test facility HoBiCaT at HZB to study TESLA-type cavities. The microphonics detuning spectral content, peak detuning values, and the driving terms for these mechanical oscillations have been analyzed. In combination with the characterization of cw-adapted fast tuning systems based on the piezoelectric effect this information has been used to design a detuning compensation algorithm. It has been shown that a compensation factor between 2–7 is achievable, reducing the typical detuning of 2–3 Hz rms to below 0.5 Hz rms. These results were included in rf-control simulations of the cavities, and it was demonstrated that a phase stability below 0.02° can be achieved.

  4. Treatment of low-activity-level process wastewaters by continuous countercurrent ion exchange

    1990-01-01

    A mobile pilot-scale continuous countercurrent ion-exchange (CCIX) system is being operated at the Oak Ridge National Laboratory (ORNL) for the treatment of wastewaters that contain predominantly calcium sodium, and magnesium bicarbonates and are slightly contaminated with 90 Sr and 137 Cs radioisotopes. A demonstration study is being conducted to evaluate the near-steady-state performance and feasibility of a pilot-scale CCIX column for the selective removal of strontium from wastewater. Test results show that the process removes strontium sufficiently from the wastewater to permit discharge while significantly reducing the volume of secondary waste generation. CCIX has the potential for effective use in several applications; however, it has not been frequently utilized by industries to date. The CCIX system could offer an economical alternative for decontamination of wastewaters containing trace amounts of contaminants prior to discharge into the environment. This paper discusses (a) application of the Thomas model for predicting breakthrough curves from ion exchange column tests, (b) methods for scaleup of experimental small-scale ion-exchange columns to industrial-scale columns, and (c) methods for predicting effluent compositions in a CCIX system. 20 refs., 6 figs., 2 tabs

  5. The relationship between amygdala activation and passive exposure time to an aversive cue during a continuous performance task.

    2010-11-01

    Full Text Available The allocation of attention modulates negative emotional processing in the amygdala. However, the role of passive exposure time to emotional signals in the modulation of amygdala activity during active task performance has not been examined. In two functional Magnetic Resonance Imaging (fMRI experiments conducted in two different groups of healthy human subjects, we examined activation in the amygdala due to cued anticipation of painful stimuli while subjects performed a simple continuous performance task (CPT with either a fixed or a parametrically varied trial duration. In the first experiment (N = 16, engagement in the CPT during a task with fixed trial duration produced the expected attenuation of amygdala activation, but close analysis suggested that the attenuation occurred during the period of active engagement in CPT, and that amygdala activity increased proportionately during the remainder of each trial, when subjects were passively exposed to the pain cue. In the second experiment (N = 12, the duration of each trial was parametrically varied, and we found that amygdala activation was linearly related to the time of passive exposure to the anticipatory cue. We suggest that amygdala activation during negative anticipatory processing depends directly on the passive exposure time to the negative cue.

    The out-of-curriculum project team "Rika-Kobo", organized by undergraduate students, has been actively engaged in a variety of continuous outreach activities in the fields of science and technology including optics and photonics. The targets of their activities cover wide ranges of generations from kids to parents and elderly people, with aiming to promote their interests in various fields of science and technologies. This is an out-of-curriculum project team with about 30 to 40 undergraduate students in several grades and majors. The total number of their activities per year tends to reach 80 to 90 in recent years. Typical activities to be performed by the project team include science classes in elementary and/or secondary schools, science classes at other educational facilities such as science museums, and experiment demonstrations at science events. Popular topics cover wide ranges from explanations and demonstrations of nature phenomena, such as rainbow colors, blue sky, sunset color, to demonstration experiments related to engineering applications, such as polarization of light, LEDs, and optical communications. Experimental topics in optics and photonics are especially popular to the audiences. Those activities are very effective to enhance interests of the audiences in learning related knowledges, irrespective of their generations. Those activities are also helpful for the student members to achieve and/or renew scientific knowledges. In addition, each of the activities provides the student members with effective and advantageous Project-Based-Learning (PBL) style experiences including manufacturing experiences, which are advantageous to cultivate their engineering skills.

    Beam halos are formed via self-consistent motion of the beam particles. Interactions of single particles with time-varying density distributions of other particles are a major source of halo. Aspects of these interactions are studied for an initially equilibrium distribution in a radial, linear, continuous focusing system. When there is a mismatch, it is shown that in the self-consistent system, there is a threshold in space-charge and mismatch, above which a halo is formed that extends to ∼1.5 times the initial maximum mismatch radius. Tools are sought for characterizing the halo dynamics. Testing the particles against the width of the mismatch driving resonance is useful for finding a conservative estimate of the threshold. The exit, entering and transition times, and the time evolution of the halo, are also explored using this technique. Extension to higher dimensions is briefly discussed

    of the enzyme and measured expansion when wetted with a reaction mixture, a filling degree of 52 vol % dry enzymes particles per column volume seemed appropriate. Twenty minutes was required to reach equilibrium conditions with a MAG content of 50-55 wt %. Only insignificant indications of mass transfer...... limitations were observed. Hence, the commercial lipase seemed adequate to use in its available particle size distribution ranging from 300 to 900 mu m. A column length-to-diameter ratio of less than 25 did not interfere with the transfer of the fluid mixture through the column. Under the tested conditions......Continuous and easily operated glycerolysis was studied in different lipase-packed columns to evaluate the most potential process set-ups for industrial monoacylglycerol (MAG) production. Practical design-related issues such as enzyme-filling degree, required reaction time, mass transfer...

    Myers-Briggs concepts are useful for understanding and managing individual and group strengths, preferences, and "blind spots." Requirements of the work to be accomplished can be matched to the strengths and preferences of the individual or group. Work groups can be selected to enhance individual strengths and to counterbalance blind spots. This article describes the experience of one hospital-based continuing education department that uses the Myers-Briggs Personality Trait Inventory to explore department members' strengths and preferences. Understanding individual preferences has helped group members to understand, anticipate, and work with one another. The ideal mix of profiles challenges and stimulates both the individual and the department. Maximizing diversity increases the potential for conflict between individuals with opposite preferences; recognizing strengths and blind spots, willingness to talk about work style differences, and a little humor all make peaceful coexistence possible.

  19. Towards the development of continuous, organocatalytic, and stereoselective reactions in deep eutectic solvents

    Full Text Available Different deep eutectic solvent (DES mixtures were studied as reaction media for the continuous synthesis of enantiomerically enriched products by testing different experimental set-ups. L-Proline-catalysed cross-aldol reactions were efficiently performed in continuo, with high yield (99%, anti-stereoselectivity, and enantioselectivity (up to 97% ee. Moreover, using two different DES mixtures, the diastereoselectivity of the process could be tuned, thereby leading to the formation, under different experimental conditions, to both the syn- and the anti-isomer with very high enantioselectivity. The excess of cyclohexanone was recovered and reused, and the reaction could be run and the product isolated without the use of any organic solvent by a proper choice of DES components. The dramatic influence of the reaction media on the reaction rate and stereoselectivity of the process suggests that the intimate architecture of DESs deeply influences the reactivity of different species involved in the catalytic cycle.

    Full Text Available We introduce an efficient hidden Markov model-based voice activity detection (VAD algorithm with time-variant state-transition probabilities in the underlying Markov chain. The transition probabilities vary in an exponential charge/discharge scheme and are softly merged with state conditional likelihood into a final VAD decision. Working in the domain of ITU-T G.729 parameters, with no additional cost for feature extraction, the proposed algorithm significantly outperforms G.729 Annex B VAD while providing a balanced tradeoff between clipping and false detection errors. The performance compares very favorably with the adaptive multirate VAD, option 2 (AMR2.
