This report provides perspectives gained by reviewing 75 Individual Plant Examination (IPE) submittals pertaining to 108 nuclear power plant units. IPEs are probabilistic analyses that estimate the core damage frequency (CDF) and containment performance for accidents initiated by internal events. The US Nuclear Regulatory Commission (NRC) reviewed the IPE submittals with the objective of gaining perspectives in three major areas: (1) improvements made to individual plants as a result of their IPEs and the collective results of the IPE program, (2) plant-specific design and operational features and modeling assumptions that significantly affect the estimates of CDF and containment performance, and (3) strengths and weaknesses of the models and methods used in the IPEs. These perspectives are gained by assessing the core damage and containment performance results, including overall CDF, accident sequences, dominant contributions to component failure and human error, and containment failure modes. Methods, data, boundary conditions, and assumptions used in the IPEs are considered in understanding the differences and similarities observed among the various types of plants. This report is divided into three volumes containing six parts. Part 1 is a summary report of the key perspectives gained in each of the areas identified above, with a discussion of the NRC`s overall conclusions and observations. Part 2 discusses key perspectives regarding the impact of the IPE Program on reactor safety. Part 3 discusses perspectives gained from the IPE results regarding CDF, containment performance, and human actions. Part 4 discusses perspectives regarding the IPE models and methods. Part 5 discusses additional IPE perspectives. Part 6 contains Appendices A, B and C which provide the references of the information from the IPEs, updated PRA results, and public comments on draft NUREG-1560 respectively.

Full Text Available Interprofessional education (IPE has been recognised internationally as a way to improve healthcare professional interactions and team working in order to enhance patient care. Since pharmacists are increasingly part of multi-professional healthcare teams and are expanding their clinical roles, many pharmacy regulators have stipulated IPE must be included in educational curricula. This study aimed to examine how different Schools of Pharmacy (SOPs in the UK implement IPE within their pharmacy course. Information about IPE was mainly obtained through interviews with staff from various SOPs. Nine telephone interviews were conducted which were analysed using a thematic analysis approach in order to derive common categories. These were identified as students, activities, barriers and facilitators and benefits of IPE. It was found that teaching methods used for IPE varied across SOPs. No standard strategy to deliver IPE was identified. Students were thought to value the IPE experience, especially the interaction with other professionals. The main barriers to implementing IPE arose from limited financial and organisational support. In general, many SOPs in the UK are undertaking IPE but challenges remain in establishing it as a routine part of the course, something which seems to echo difficulties in implementation of IPE both nationally and internationally.

This paper discusses the core damage frequency (CDF) insights gained by analyzing the results of the Individual Plant Examinations (IPES) for two groups of plants: boiling water reactor (BWR) 3/4 plants with Reactor Core Isolation Cooling systems, and Westinghouse 4-loop plants. Wide variability was observed for the plant CDFs and for the CDFs of the contributing accident classes. On average, transients-with loss of injection, station blackout sequences, and transients with loss of decay heat removal are important contributors for the BWR 3/4 plants, while transients, station blackout sequences, and loss-of-coolant accidents are important for the Westinghouse 4-loop plants. The key factors that contribute to the variability in the results are discussed. The results are often driven by plant-specific design and operational characteristics, but differences in modeling approaches are also important for some accident classes

Human action perspectives based on individual plant examination results

Forester, J.; Thompson, C.; Drouin, M.; Lois, E.

1996-01-01

This paper provides perspectives on human actions gained from reviewing 76 individual plant examination (IPE) submittals. Human actions found to be important in boiling water reactors (BWRs) and in pressurized water reactors (PWRs) are presented and the events most frequently found important are discussed. Since there are numerous factors that can influence the quantification of human error probabilities (HEPs) and introduce significant variability in the resulting HEPs (which in turn can influence which events are found to be important), the variability in HEPs for similar events across IPEs is examined to assess the extent to which variability in results is due to real versus artifactual differences. Finally, similarities and differences in human action observations across BWRs and PWRs are examined

Cost reduction at NSP using IPE results

Asmus, T.J.

1995-01-01

Operating nuclear power generating facilities are under increasing pressure to reduce costs to be able to compete successfully in the competitive electric sales market of today. With the completion of the individual plant evaluations (IPEs), numerous opportunities exist for application of probabilistic risk assessment methodology to reduce production costs. This paper presents two nontraditional methods in which IPE results can be used to help reduce nuclear insurance coverage limits and local property taxes. Significant savings can be realized through use of either of these two methods

Methodology to classify accident sequences of an Individual Plant Examination according to the severe releases for BWR type reactors

International Nuclear Information System (INIS)

Sandoval V, S.

2001-01-01

The Light Water Reactor (LWR) operation regulations require to every operating plant to perform of an Individual Plant Examination study (Ipe). One of the main purposes of an Ipe is t o gain a more quantitative understanding of the overall probabilities of core damage and fission product releases . Probabilistic Safety Analysis (PSA) methodologies and Severe Accident Analysis are used to perform Ipe studies. PSA methodologies are used to identify and analyse the set of event sequences that might originate the fission product release from a nuclear power plant; these methodologies are combinatorial in nature and generate thousands of sequences. Among other uses within an Ipe, severe accident simulations are used to determine the characteristics of the fission product release for the identified sequences and in this way, the releases can be understood and characterized. A vast amount of resources is required to simulate and analyse every Ipe sequence. This effort is unnecessary if similar sequences are grouped. The grouping scheme must achieve an efficient trade off between problem reduction and accuracy. The methodology presented in this work enables an accurate characterization and analysis of the Ipe fission product releases by using a reduced problem. The methodology encourages the use of specific plant simulations. (Author)

Severe accident progression perspectives for Mark I containments based on the IPE results

International Nuclear Information System (INIS)

Lin, C.C.; Lehner, J.R.; Pratt, W.T.; Drouin, M.

1995-01-01

Based on level 2 analyses in IPE (Individual Plant Examination) submittals accident progression, perspectives were obtained for all containment types. These perspectives consisted of insights on containment failure modes, releases therein, and factors responsible for the results. To illustrate the types of perspectives acquired on severe accident progresssion, insights obtained for (BWR) Mark I containments are discussed here. Mark I containments have high strength but small volumes and rely on pressure suppression pools to condense steam released from the reactor coolant system during an accident. Accidents causing structural failure of the drywell shortly after the core debris melts through the reactor vessel were found to be dominant contributors to risk. Importance of individual containment failure mechanisms depends on plant features and in some cases on modeling assumptions; however the following mechanisms were found important: drywell shell melt-through caused by direct contact with core debris and drywell failure caused by rapid pressure/temperature pulses at time of vessel melt-through. Drywell failure caused by gradual pressure/temperature buildup due to gases and steam released during core/concrete interactions is important in some IPEs. In other IPEs vent was an important contributor. However, accidents that bypass containment (eg interfacing systems LOCA)or involve containment isolation failure were not important contributors to the CDF in any of the IPEs for Mark I plants. These accidents are also not important to risk (even though they can involve large fission product release) because their frequencies of occurrence are so much lower than frequencies of early structural failure caused by other accidents that dominate the CDF

Individual plant examination and future PRA applications

PRA is being used in many areas of plant operation as has been demonstrated in previous studies. With the U.S. NRC's emphasis on the use of risk to identify plant vulnerabilities and the development of plant specific PRA models for all plants, it is expected that the use of PRA will be expanded. Key areas where this is expected to occur include the development of risk-based Technical Specifications, risk management, and risk-centered maintenance programs. This paper focuses on the Individual Plant Examination requirement and the possible uses of risk-based methods in controlling plant operation to enhance plant safety and availability, and how the IPE requirement will potentially further this area of development.

To examine whether iris pigment epithelial (IPE) cells transplanted into the subretinal space of Royal College of Surgeons (RCS) rats have the ability to rescue photoreceptors. Rat IPE (rIPE) or human IPE (hIPE) cells were transplanted subretinally in 23-day-old RCS rats. Sham injection and transplantation of ARPE-19 cells served as controls. After 12 weeks, eyes were evaluated for photoreceptor survival by morphometric analysis and electron microscopy. Morphometric analysis showed photoreceptor rescue in all transplanted and sham-injected animals (number of photoreceptors/300 microm retina+/-sd: rIPE 41.67 +/- 28; hIPE 29.50 +/- 16; ARPE-19 36.12 +/- 21; sham 16.56 +/- 6) compared to age-matched, control rats (number of photoreceptors/300 microm retina+/-sd: 9.71 +/- 4). Photoreceptor rescue was prominent in IPE cell-transplanted rats and was significantly greater than sham-injected eyes (p = 0.02 for rIPE and p = 0.04 for hIPE). Since IPE cells transplanted into the subretinal space have the ability to rescue photoreceptors from degeneration in the RCS rat without any harmful effects, IPE cells may represent an ideal cell to genetically modify and thus carry essential genetic information for the repair of defects in the subretinal space.

1996-01-01

The primary goal of the Individual Plant Examination (IPE) Program was for licensees to identify plant-unique vulnerabilities and actions to address these vulnerabilities. A review of these vulnerabilities and plant improvements that were identified in the IPEs was performed as part of the IPE Insights Program sponsored by the U.S. Nuclear Regulatory Commission (NRC). The purpose of this effort was to characterize the identified vulnerabilities and the impact of suggested plant improvements. No specific definition for open-quotes vulnerabilityclose quotes was provided in NRC Generic Letter 88-20 or in the subsequent NRC IPE submittal guidance documented in NUREG-1335. Thus licensees were left to use their own definitions. Only 20% of the plants explicitly stated that they had vulnerabilities. However, most licensees identified other plant improvements to address issues not explicitly classified as vulnerabilities, but pertaining to areas in which overall plant safety could potentially be increased. The various definitions of open-quotes vulnerabilityclose quotes used by the licensees, explicitly identified vulnerabilities, proposed plant improvements to address these vulnerabilities, and other plant improvements are summarized and discussed

The fundamental objective of the accident management program is to assure, in the event of a severe accident at a nuclear plant, that the effectiveness of personnel and equipment is maximized in preventing or mitigating the consequences of the accident. This document studies the use of NUREG-1150 and IPEs in accident management. Figs

Globalising the classical foundations of IPE thought

Eric Helleiner

2015-12-01

Full Text Available Abstract Current efforts to teach and research the historical foundations of IPE thought in classical political economy in the 18th, 19th and early 20th centuries centre largely on European and American thinkers. If a more extensive 'global conversation' is to be fostered in the field today, the perspectives of thinkers in other regions need to be recognised, and brought into the mainstream of its intellectual history. As a first step towards 'globalising' the classical foundations of IPE thought, this article demonstrates some ways in which thinkers located beyond Europe and the United States engaged with and contributed to debates associated with the three well-known classical traditions on which current IPE scholarship often draws: economic liberalism, economic nationalism and Marxism. It also reveals the extensive nature of 'global conversations' about IPE issues in this earlier era.

[Implementing Inter-Professional Education (IPE): Challenges and Strategies].

Lee, Chia-Lun; Hung, Chich-Hsiu

2017-12-01

Inter-professional practice (IPP), necessary in today's healthcare environment, should be guided and practiced through inter-professional education (IPE). Within the context of an effective IPE program, collaborative medical professionals must be cognizant of the demands of patients' integrated care, organize a collaborative inter-professional team, and achieve the objectives of patient-centered care. However, the many challenges of IPE include insufficient understanding of inter-professional care, occupational culture-related boundary issues, lack of a college education, and insufficient support from academic and medical institutions. This article suggests adopting effective strategies to promote inter-professional recognition, create a harmonious medical culture, eliminate barriers to education, and enhance support for academic and medical institutions. Inter-professional collaboration between academic and clinical institutions must provide resources and substantive professional training. Effectively implementing IPE and IPP is expected to elicit trust, respect, and efficient communication from team members.

Injecting use of image and performance-enhancing drugs (IPED) in the general population is a public health concern. A wide and varied range of IPED are now easily accessible to all through the online market. A comprehensive literature review was undertaken according to Critical Appraisal Skills Programme (CASP) guidelines for systematic review, to identify the relevant literature. No date restrictions were placed on the database search in the case of human growth hormone melanotan I and II, and oil and cosmetic injectables. In the case of anabolic androgenic steroids search dates were restricted to January 2014-2015. Publications not in English and with a lack of specificity to the topic were excluded. The review yielded 133 relevant quantitative and qualitative papers, clinical trials, clinical case presentations and editorials/reports. Findings were examined/reviewed under emergent themes which identified/measured extent of use, user profiling, sourcing, product endorsement, risk behaviours and health outcomes in users. Motivation for IPED use may be grounded in appearance, pursuit of health and youth, and body image disturbance. IPED users can practice moderated use, with pathological use linked to high-risk behaviours, which may be normalised within IPED communities. Many IPED trajectories and pathways of use are not scientifically documented. Much of this information may be available online in IPED specific discussion forums, an underutilised setting for research, where uncensored discourse takes place among users. This review underscores the need for future internet and clinical research to investigate prevalence and patterns of injecting use, and to map health outcomes in IPED users. This paper provides community-based clinical practice and health promotion services with a detailed examination and analysis of the injecting use of IPED, highlighting the patterns of this public health issue. It serves to disseminate updated publication information to health

As the United States health care model progresses towards medical teams and the country's population continues to diversify, the need for health professional education programs to develop and implement culturally specific interprofessional education (IPE) becomes increasingly imperative. A wide range of models exists for delivering and implementing IPE in health education, but none have included the cultural components that are vital in educating the health professional. A cross-cultural decentralized IPE model for physician assistant (PA) and physical therapy (PT) students was developed. This three-part IPE series was created using an established cultural curricular model and began with the exploration of self, continued with the examination of various dimensions of culture, and concluded with the exploration of the intersection between health and culture. We assessed student satisfaction of the IPE experiences and students' engagement and attitudes towards IPE using a three-item open-ended questionnaire administered after each cross-cultural activity and the Interprofessional Education Series Survey (IESS) upon the completion of the series. IESS responses showed that PA and PT students reported benefits in interprofessional collaboration and cultural awareness and expressed overall satisfaction with the series. Qualitative analysis revealed growth in student response depth consistent with the scaffolded focus of each IPE module in the series. The trends in this three-part series suggest that institutions looking to develop culturally inclusive IPE educational initiatives may have success through a decentralized model mirroring the effective cultural progression focused on addressing exploration of self, examination of various dimensions of culture, and exploration of the intersection between health and culture.

Technetium-99m p-iodophenethyldiaminodithiol (DADT-IPE): potential brain perfusion imaging agent for SPECT

Shiba, K.; Mori, H.; Matsuda, H.; Hisada, K.

1992-01-01

A new ligand, an N-p-iodophenethyl diaminodithiol (DADT-IPE), an analog of N-isopropyl-p-iodoamphetamine (IMP), was synthesized and subsequently complexed with 99m Tc, using stannous chloride as a reducing agent. Two complexes (a and b) were separated from 99m Tc-DADT-IPE by high performance liquid chromatography (HPLC). Competitive inhibition studies showed that the IC 50 value of DADT-IPE (70 μM) was similar to that of IMP (49 μM). Biodistribution studies of one of the complexes [ 99m Tc-DADT-IPE(a)] in rats showed that 0.65% of the injected dose of the tracer remained in the brain at 5 min after intravenous injection, with 0.53% of the dose remaining in the brain at 60 min post-injection, whereas the corresponding values for the other complex [ 99m Tc-DADT-IPE(b)] were 0.34% dose in the brain at 5 min and 0.28% dose in the brain at 60 min post-injection. The half-life for clearance of 99m Tc-DADT-IPE(a) from rat brain was found to be more than 5h. These results suggested that 99m Tc-DADT-IPE(a) has characteristics which are suitable for cerebral perfusion imaging. (author)

Effects of NYMEX trading on IPE Brent Crude futures markets: a duration analysis

International Nuclear Information System (INIS)

Lin, S.X.; Tamvakis, M.N.

2004-01-01

Recent developments in the energy markets, and the surge and dip in crude oil prices over the last few years, have renewed the interest in the workings of the two main price setting markets: London's International Petroleum Exchange (IPE) and New York's Mercantile Exchange (NYMEX). The interaction of these two markets, when both of them are open (synchronous trading) and when only London is open (asynchronous trading), is important, in view of the fact that most participants take positions in both markets. This paper looks at how London is affected by New York by analysing the transaction duration of the IPE Brent futures contract, both when the NYMEX WTI futures contract is being traded and when NYMEX is closed. Using tick-by-tick data obtained from IPE, transaction durations are found to form two distinctive and inverted U-shaped patterns. Autoregressive conditional duration (ACD) model, first introduced by Engle and Russell, is applied to the data. Parameters of IPE morning and afternoon are significantly different from each other, underlining the dominant effects of NYMEX on IPE trading. The results from the current analysis reinforce previous results by the authors, which indicate that NYMEX is a leading price setter in crude oil futures prices and has a dominant effect on the IPE-traded contracts

A structured approach to individual plant evaluation and accident management

International Nuclear Information System (INIS)

Klopp, G.T.

1991-01-01

The current requirements for the performance of individual plant evaluations (IPE's) include the derivation of accident management insights as and if they occur in the course of finalizing an IPE. The development of formal, structured accident management programs is, however, explicitly excluded from current IPE requirements. The Nuclear Regulatory Commission is following the Nuclear Management and Resources Council (NUMARC) efforts to establish the framework(s) for accident management program development and plants to issue requirements on such development at a later date. The Commonwealth Edison program consists of comprehensive level 2 PRA's which address the requirements for IPE's and which go beyond those requirements. From the start of the IPE efforts, it was firmly held, within Edison, that the best way to fully and economically extract a viable accident management program from an IPE was to integrate the two efforts from the start and include the accident management program development as a required IPE product

Exploring the relationship between online buyers and sellers of image and performance enhancing drugs (IPEDs): Quality issues, trust and self-regulation.

Science.gov (United States)

van de Ven, Katinka; Koenraadt, Rosa

2017-12-01

Online drug markets are expanding the boundaries of drug supply including the sale and purchase of image and performance enhancing drugs (IPEDs). However, the role of the internet in IPED markets, and in particular the ways in which these substances are supplied via the surface web, has rarely been considered. This article examines the online IPED market in order to inform drug policy and to provide a nuanced understanding of retailers involved, particularly exploring the relationship between buyers and sellers. This paper is based on two extensive research projects conducted in the Netherlands and Belgium. The first project focuses on muscle drugs and is based on 64 IPED dealing cases, semi-structured interviews with authorities (N=32), and dealers (N=15), along with an analysis of 10 steroid-selling websites. The second research project primarily focuses on weight loss drugs and sexual enhancers in the Netherlands, and relies on interviews with authorities (N=38), suppliers (N=30), and consumers (N=10), analysis of 69 criminal case files, and an online analysis. In the literature, the illicit online sale of IPEDs is generally associated with illegal online pharmacies that try to mislead buyers. While confirmed in our research, we also illustrate that there are online suppliers who invest in customer relationships and services, and that users are aware of the illegal nature of their business. These e-vendors incorporate a 'social supply business model' by providing the best possible service to their customers and attempting to minimise risks in order to attract, satisfy and maintain customers. As it is likely that users will continue to make use of the internet to order IPEDs, regardless of closing down selling websites, it is first of all important to counteract these online sources by educating all types of consumers and providing harm reduction services.

Risk management of the North Anna Power Station Service Water System Preservation Project using the IPE model

International Nuclear Information System (INIS)

Afzali, A.; Donovan, M.D.; Sartain, M.D.; Bankley, A.V.

1993-01-01

This paper discusses the application of the North Anna Power Station Individual Plant Examination (IPE) models in PRA study of the Service Water System Preservation Project (SWSPP). The service water project involves repair and restoration of the Service Water System (SWS) piping and will require excavation of the buried SWS lines in addition to temporarily removing one of the two redundant SWS loops from operation. The SWSPP will be carried out with one or both units in normal operation. The objective of the PRA study was to quantify the risk impact (as measured by the change in Core Damage Frequency (ΔCDF)) of the SWSPP and to identify and evaluate countermeasures to reduce the risk impact of the project activities. The study concluded that the ΔCDF would be acceptable by undertaking preventative measures and by providing additional accident mitigating measures during performance of the SWSPP activities

Students' motivation for interprofessional collaboration after their experience on an IPE ward: A qualitative analysis framed by self-determination theory.

Interprofessional Education (IPE) may depend for its success not only on cognitive gains of learners, but also on affective and motivational benefits. According to Self-Determination Theory (SDT), a major motivation theory, autonomy (feeling of choice), competence (feeling of capability), and relatedness (feeling of belonging) drive motivation in a way that can improve performance. We investigated which elements of IPE in a clinical ward potentially influence students' feelings in these three areas. We conducted semi-structured interviews with 21 students from medicine, nursing, pharmacy, and physical therapy attending a three-week IPE ward and analyzed the data using a realist approach. Two researchers independently identified meaning units using open coding. Thirteen themes were synthesized. Next, meaning units, expressing autonomy, competence, or relatedness were discerned. Students appeared motivated for an IPE ward, with its authentic situations making them feel responsible to actively contribute to care plans, by understanding how professions differ in their contributions and analytic approach and by informal contact with other professions, enhanced by a dedicated physical space for team meetings. Students valued the IPE ward experience and autonomous motivation for IPE was triggered. They mentioned practical ways to incorporate what they learned in future interprofessional collaboration, e.g. in next placements.

The soft X-ray beamline IPE is one of the first phase SIRIUS beamlines at the LNLS, Brazil. Divided into two branches, IPE is designed to perform ambient pressure X-ray photo-electron spectroscopy (AP-XPS) and high resolution resonant inelastic X-ray scattering (RIXS) for samples in operando/environmental conditions inside cells and liquid jets. The aim is to maximize the photon flux in the energy range 200-1400 eV generated by an elliptically polarizing undulator source (EPU) and focus it to a 1 μm vertical spot size at the RIXS station and 10 μm at the AP-XPS station. In order to achieve the required resolving power (40.000 at 930 eV) for RIXS both the dispersion properties of the plane grating monochromator (PGM) and the thermal deformation of the optical elements need special attention. The grating parameters were optimized with the REFLEC code to maximize the efficiency at the required resolution. Thermal deformation of the PGM plane mirror limits the possible range of cff parameters depending of the photon energy used. Hence, resolution of the PGM and thermal deformation effects define the boundary conditions of the optical concept and the simulations of the IPE beamline. We compare simulations performed by geometrical ray-tracing (SHADOW) and wave front propagation (SRW) and show that wave front diffraction effects (apertures, optical surface error profiles) has a small effect on the beam spot size and shape.

Interprofessional education (IPE) is a central feature of modern education in the health care professions. Despite this, empirically founded and systematically structured IPE courses are absent from many curricula. To answer the WHO's call for improved interprofessional collaboration in the health care system, a seminar was designed, implemented and evaluated. The target group consisted of students beginning nursing and medical studies (first and second semesters) and physiotherapy students (first year of training). The aim was to develop a basic IPE module focusing not only on the demands placed by academia and politics, but also the interests of the target group. This module was evaluated on the basis of the modified four-level Kirkpatrick approach. Based on focus group interviews analyzed qualitatively using Mayring's content analysis, it was possible to define five learning objectives and develop four practice-oriented modules. The seminar was then implemented and evaluated using written pre- and post-seminar evaluations and group discussions. Analysis confirmed the success of the IPE concept in that the seminar was positively rated by attendees not only in terms of their immediate reactions, but also attitude, knowledge and skills according to Kirkpatrick. In the future, it is intended to offer the IPE module on a permanent basis and assess the competencies acquired in the seminar using observation. Courses to ensure sustained learning outcomes would also be desirable.

Accident progression perspectives were gathered from the level 2 PRA analyses (the analysis of the accident after core damage has occurred involving the containment performance and the radionuclide release from the containment) described in the IPE submittals. Insights related to the containment failure modes, the releases associated with those failure modes, and the factors responsible for the types of containment failures and release sizes reported were obtained. Complete results are discussed in NUREG-1560 and summarized here

Is IPE just 'boring',1 or committed to problematic meta-theoretic|al assumptions? A critical engagement with the politics of method

Full Text Available Abstract In my contribution to this forum on IPE, my aim is to add further to the critical interventions in the debate ignited by Benjamin Cohen. The call to discuss the state of IPE has been timely, though not only because (some IPE journals have indeed become uninteresting; much more is at stake. Intellectual debate in the field has now not only narrowed, but has also shifted away from engaging the underlying premises of (global development, inequalities, and relations of domination. As such, the mainstream framing of IPE is arguably also implicated in a project of 'gate-keeping'. This is not to say that the intellectual richness and creativity that Cohen has called for in the study of IPE does not exist; such work is pursued by scholars of IR, more broadly conceived, and not just by those in other disciplines. Such richer scholarship has for instance, been advanced by historical sociologists, postcolonial theorists, and critical scholars of global development/global political economy including many working from feminist political-economic perspectives. The absence of an engagement with such perspectives in the mainstream of IPE can perhaps be explained to some extent by reference to ideological dispositions and attempts to maintain a hold on the disciplinary core along epistemological and methodological premises committed to ostensibly power-free and value-free analysis. The consequences are felt, as Cohen notes, also in the context of training and preparing future generations of IPE scholars, where current practices tend to reproduce students unable to 'ask and respond to the big questions', and who have instead come to be satisfied with applying 'accepted' methods. Critical scholars, on the other hand, have continuously pushed beyond the analytical and theoretical boundaries, engaging for example, with questions of power, domination and resistance, and more often than not such analyses are grounded in empirical research.

Millstone Unit 1 plant vulnerabilities during postulated severe nuclear accidents

International Nuclear Information System (INIS)

Khalil, Y.F.

1993-01-01

Generic Letter 88-20, Supplement No. 1 (Ref. 1), issued by the Nuclear Regulatory Commission (NRC) requested all licensees holding operating licenses and construction permits for nuclear power reactor facilities to perform Individual Plant Examinations (IPE) of their plant(s) for severe accident vulnerabilities and to submit the results to the Commission. This paper summarizes the major Front-End (Level-1 PRA) and Back-End (Level-2 PRA) insights gained from the Millstone Unit 1 (MP-1) IPE study. No major plant vulnerabilities have been identified from a Front-End perspective. The Back-End analysis, however, has identified two potential containment vulnerabilities during postulated events that progress beyond the Design Basis Accidents (DBAs), namely, (1) MP-1 is dominated by early source term releases that would occur within a six-hour time frame from time of accident initiation, or reactor trip, and (2) MP-1 containment is somewhat vulnerable to leak-type failure through the drywell head. As a result of the second finding, a recommendation currently under evaluation, has been made to increase the drywell head bolt's preload from 54 Kips to resist the containment design pressure value (62 psig)

GLObal RIsk MANagement system for plant operations GLORIMAN

International Nuclear Information System (INIS)

Silverman, Eugene B.

2004-01-01

Considerable effort has been expended by nuclear power plants in the preparation of their Independent Plant Evaluation (IPE) programs. The result of these projects is the generation of very useful information concerning plant operations, states, availability and risk. The potential application of this information is often unrealized due to the unwieldy form of the data as reported in the IPE. Plant personnel would benefit greatly from quick access to risk information as a means of supporting day-to-day decisions, but the information exists only in a difficult to understand and inaccessible form. There is a need to translate the costs invested in Probabilistic Risk Assessment (PRA) projects into a useable tool for plant personnel. This paper describes a software tool developed by ARD Corporation to be used by plants to assist in determining the operational risks and benefits associated with modifying the plant state during normal and off-normal operations for performing maintenance. This tool integrates a relational database with an easy-to-use graphical user interface and several unique software features. The result is a responsive, easy-to-understand tool that integrates an organization's PRA/IPE into the operational and maintenance needs of the station. The Global Risk Management System is designed to allow the user to evaluate the risk associated with current and proposed plant states. The impact of changes in plant configuration, operational modes and equipment availability are assessed from a risk management perspective, but displayed in an easy-to-understand form for personnel not familiar with risk methodology. Additionally, pipe and instrumentation drawings can be retrieved by the user and displayed as a reference tool. (author)

To examine the diagnostic sensitivity and specificity of dopamine transporter SPECT imaging with a highly dopamine transporter selective radioligand. The study included consecutively enrolled, drug-naive patients with an average short history of parkinsonian motor symptoms, referred for diagnostic scanning. The study group comprised 288 patients naive to antiparkinson treatment who were enrolled as they were admitted for a diagnostic SPECT scan with the radioligand [ 123 I]-N-(3-iodoprop-2E-enyl)-2-β-carbomethoxy-3β-(4-methylphenyl)n ortropane ( 123 I-PE2I). After the diagnostic scanning, patients were followed clinically with an average follow-up of 19.7 ± 12.5 months. A diagnosis could be clinically settled in 189 patients and among these patients, a dopamine transporter scan had a sensitivity of 88% and a specificity of 91% for discrimination between patients with and without striatal neurodegeneration. In cognitively impaired patients (Mini Mental State Examination 2 differentiated between idiopathic Parkinson's disease and atypical parkinsonian syndromes with a specificity of 84% and a sensitivity of 63%. In drug-naive patients with subtle clinical parkinsonian motor symptoms, dopamine transporter scan using 123 I-PE21 has a high sensitivity and specificity in distinguishing between patients with and without striatal neurodegeneration. The specificity is lower in patients who are also cognitively impaired. Calculation of the striatal APR can assist in differentiating between idiopathic Parkinson's disease and atypical parkinsonian syndromes. (orig.)

A comparative emissions study was conducted on combustion products of various solid domestic cooking fuels; the objective was to compare relative levels of organic and inorganic toxic emissions from traditional Pakistani fuels (wood, wood charcoal, and dried animal dung) with manufactured low-rank coal briquettes (Lakhra and Sor-Range coals) under conditions simulating domestic cooking. A small combustion shed 12 m 3 internal volume, air exchange rate 14 h -1 was used to simulate south Asian cooking rooms. 200-g charges of the various fueb were ignited in an Angethi stove located inside the shed, then combusted to completion; effluents from this combustion were monitored as a function of time. Measurements were made of respirable particulates, volatile and semi-volatile organics, CO, SO 2 , and No x . Overall it appears that emissions from coal briquettes containing combustion amendments (slaked lime, clay, and potassium nitrate oxidizer) are no greater than emissions Erom traditional fuels, and in some cases are significantly lower; generally, emissions are highest for afl fuels in the early stages of combustion

A thermophilic lactic acid (LA) producer was isolated and identified as Bacillus coagulans strain IPE22. The strain showed remarkable capability to ferment pentose, hexose and cellobiose, and was also resistant to inhibitors from lignocellulosic hydrolysates. Based on the strain's promising features, an efficient process was developed to produce LA from wheat straw. The process consisted of biomass pretreatment by dilute sulfuric acid and subsequent SSCF (simultaneous saccharification and co-fermentation), while the operations of solid-liquid separation and detoxification were avoided. Using this process, 46.12 g LA could be produced from 100g dry wheat straw with a supplement of 10 g/L corn steep liquid powder at the cellulase loading of 20 FPU (filter paper activity units)/g cellulose. The process by B. coagulans IPE22 provides an economical route to produce LA from lignocellulose. Copyright © 2014 Elsevier Ltd. All rights reserved.

State of Level 2 analyses and severe accident management in Spanish nuclear power plants

Otero, R.

1998-01-01

The state of the PSA/IPE studies in the Spanish NPPs is presented in this report, as well as the plans to implement the severe accident management strategy both in the Spanish BWRs and PWRs. First, the Spanish LWRs are introduced, and the scope of the IPE analyses required by the Spanish Regulatory Commission (CSN) is given. The general overview is completed with the current degree of development for the IPE studies in each plant. In the second part the methods and tools are shown which are used by the Spanish plants to develop their Level 2 analysis. The different strategies for severe accident management adopted by the BWPs and PWRs in Spain are also outlined. The sources and implementation of the Severe Accident Guidelines (SAG) are described. More detail is given in the following chapters to the containment analysis of Trillo (PWR, KWU design) and Cofrentes (BWR/6, GE design) NPPs, whose development is being carried out by IBERDROLA. The analysis which has been performed up to date for Trillo is limited to the Plant Damage State (PDS) definition. However, the main phenomena challenging its containment performance have been identified, and they are summarized here. The Level 2 analysis for Cofrentes is comparatively more developed. The main phenomena and the key equipment affecting its containment behaviour are presented. Finally the conclusions of this report are elaborated. (author)

A re-evaluation of nuclear plant offsite power supplies

International Nuclear Information System (INIS)

William E Berger; Robert E Henry

2005-01-01

Full text of publication follows: De-regulation of the electric power industry has resulted in separate ownership of the transmission and power generation facilities as well as a revised format for operating the transmission facilities. Currently we see the transfer of large blocks of bulk power between markets which can impact the voltage regulation at the offsite power supply. Where Nuclear Plant operations once knew with a large degree of certainty the operating range of the system supplying the offsite power supply, this may no longer be the case and more challenges to the safety systems could result. These challenges may manifest themselves as either a loss of offsite power or voltage levels approaching the degraded level setpoints. In this paper we will first explore what challenges are caused by deregulation and how they impact offsite power supply operations. Next we will incorporate the knowledge grained regarding accidents and consequences from the Individual Plant Evaluations (IPE's) to see how the offsite power supply could be operated to mitigate the challenges and extend the capacity of the auxiliary power system. Various scenarios will be examined using the Modular Accident Analysis Program (MAAP) as an integral plant model. MAAP simulations that include both the plant thermal hydraulic responses and corresponding electric power demand are presented to demonstrate the impact of alternate approaches to offsite power system operation. The original design phase of the offsite and onsite power distribution system was based on a criterion relating to the starting of all safety loads if a safety injection signal was present independent of the accident or its progression. The IPE and risk informed insights that are readily available today will be applied in the re-analyses of the offsite distribution system response. (authors)

Peer review for USI A-46 and the seismic IPE

International Nuclear Information System (INIS)

Smith, P.; Johnson, H.

1993-01-01

Two major seismic re-evaluation programs are underway at many US nuclear power plants. Over 60 units are being examined as part of the Nuclear Regulatory Commission's (NRC's) Unresolved Safety Issue A46 (Seismic Qualification of Equipment in Operating Plants). In addition, almost all plants are being examined as part of the seismic portion of NRC's Individual Plant Examination of External Events for Severe Accident Vulnerabilities. Both programs require an independent peer review of the evaluation performed by the utility. This paper presents observations on peer reviews, based on the authors's experience with them. Suggestions are presented on the scope of peer review, as well as some of the unique peer review issues inherent to these seismic programs

The need for experienced healthcare professionals to work with older adults is great, yet educational training is limited. In this interprofessional education (IPE) study, 861 students from five professions made 293 visits in the homes or preferred community settings of 208 older adults. Surveys with quantitative and open-text feedback assessed attitudes towards older adults, IPE team functioning, and the value of home visits. Survey results showed strongly positive attitudes towards ageing and older adults. Students from all professions expressed surprise and admiration for the active lives led by these healthier older adults, lives clearly in contrast to stereotypes of ageing. They further acknowledged the value of collaborative team functioning in meeting older adult needs, learned more about the roles and responsibilities of other professions, and identified strengths of the home as a site for care. Students positively valued the experience as part of their professional training, with 82% of all students stating they would welcome additional IPE opportunities. Results suggest that an experiential IPE activity can positively shape student attitudes towards older adults, IPE, and interprofessional collaboration.

Impact of recovery actions on IPE back-end results

International Nuclear Information System (INIS)

Guey, Ching; Kabadi, Jay

1993-01-01

This paper presents a sensitivity study of the impact of various recovery/accident management actions on the IPE results. The human actions studied include: (1) RWST replenishment; (2) depressurization; (3) AC power recovery; (4) Component Cooling Water (CCW) cross-connection; and (5) manual actuation of containment spray (cavity flooding). The results indicate that the total frequency of severe accident sequences involving containment failure is lower than 1.0 x E-6/yr when all these recovery/accident management actions are taken credit. It is concluded that with appropriate considerations of operator actions in Emergency Operating Procedures (EOPs) and future accident management policy, the uncertain phenomenological issues may not play as important a role as they do now. Although the actual nonrecovery probability used in this study may be refined during future implementation of the accident management policy, the results of this study indicate that the frequency of severe accidents in which the reactor vessel fails is low when the recovery/accident management actions are taken credit. It is also clear from the study that with major recovery actions (such as RWST replenishment, AC power recovery and depressurization) being taken credit, additional accident management type of actions (e.g. manual actuation of containment spray and CCW cross-connection) may not be as effective in reducing the risk

The current status of interprofessional education (IPE) in Australian and New Zealand universities is largely unexamined despite its generally acknowledged benefit. Data are also limited about the use of IPE in teaching medication safety to nursing, pharmacy and medical students. For this reason a web-based cross-sectional survey was used to gather information from Australian and New Zealand universities offering nursing, pharmacy or medical programs. Responses were received from 31 of the 43 (72%) target universities. Eighty percent of the participants indicated that they currently offer IPE experiences, but only 24% of these experiences met the accepted definition of IPE. Of the participants who offer IPE as defined by Center for the Advancement of Interprofessional Education, only 50% use it to teach medication safety. Timetabling restrictions and lack of appropriate teaching and learning resources were identified as the main barriers to implementation of IPE. All participants reported that staff development, multi-media and e-learning resources would be beneficial to IPE initiatives and the teaching of medication safety. Innovative approaches will be needed to overcome the barriers and facilitate the uptake of quality IPE more broadly. Web-based and e-learning options promise a possible way forward, particularly in the teaching of medication safety to nursing, pharmacy and medical students.

A critical examination of the role of appreciative inquiry within an interprofessional education initiative.

Dematteo, Dale; Reeves, Scott

2011-05-01

Appreciative inquiry (AI) is a relatively new approach to initiating or managing organizational change that is associated with the 'positiveness' movement in psychology and its offshoot positive organizational scholarship. Rather than dwelling upon problems related to change, AI encourages individuals to adopt a positive, constructive approach to managing change. In recent years, AI has been used to initiate change across a broad range of public and private sector organizations. In this article, we report findings from a subset of 50 interviews gathered in a wider study of interprofessional education (IPE) in which AI was employed as a change agent for implementing IPE in a number of health care institutions in a North American setting. A multiple case study approach. (Yin, 2002) was employed in the wider study and semi-structured interviews were undertaken with participants both before their IPE programs and directly afterwards to obtain a detailed understanding of their expectations and experiences of IPE. Interviews were analyzed in an inductive thematic manner in order to produce key emergent themes from each of the IPE programs. A process of re-analysis provided a set of themes which offered an understanding of the role of AI within this IPE initiative. Our findings identify a strong resonance and fit for AI both among the health and social care professionals who participated in this initiative. Numerous individuals commented on the enthusiasm and energy AI engendered, while praising its ability to enhance their working lives and interprofessional relationships. Yet a number of difficulties were also reported. These focused on problems with the translation of the AI process into achievable structural level (e.g. professional, cultural) changes. Based on these findings, the article goes on to argue that the use of AI can overlook a number of structural factors, which will ultimately limit its ability to actually secure meaningful and lasting change within

Mechanized ultrasonic examination of piping systems in nuclear power plants

International Nuclear Information System (INIS)

Edelmann, X.; Pfister, O.; Allidi, F.

1988-01-01

The success of mechanized ultrasonic examination applied on welds in piping systems in nuclear power plants is highly dependent on its careful preparation. From the development of an adequate examination technique to its implementation on site, many problems are to be solved. This is especially the case when dealing with austenitic welds or dissimilar metal welds. In addition to the specific needs for examination technique based on material properties and requirements for minimum flaw size detection, accessibility and radiation aspects have to be considered. A crew of skilled and highly trained examination personnel is required. Experience in various nuclear power plants, - BWR's and PWR's of different designs - has shown, that even difficult examination problems can be successfully solved, provided that there is a good preparation. The necessary step by step proceeding is illustrated by examples concerning mechanized examination. Preservice inspections and in-service inspections with specific requirements, due to the types of flaws to be found or the type of material concerned, are discussed

NPP Krsko Severe Accident Management Guidelines Implementation

International Nuclear Information System (INIS)

Basic, I.; Krajnc, B.; Bilic-Zabric, T.; Spiler, J.

2002-01-01

Severe Accident Management is a framework to identify and implement the Emergency Response Capabilities that can be used to prevent or mitigate severe accidents and their consequences. The USA NRC has indicated that the development of a licensee plant specific accident management program will be required in order to close out the severe accident regulatory issue (Ref. SECY-88-147). Generic Letter 88-20 ties the Accident management Program to IPE for each plant. The SECY-89-012 defines those actions taken during the course of an accident by the plant operating and technical staff to: 1) prevent core damage, 2) terminate the progress of core damage if it begins and retain the core within the reactor vessel, 3) maintain containment integrity as long as possible, and 4) minimize offsite releases. The subject of this paper is to document the severe accident management activities, which resulted in a plant specific Severe Accident Management Guidelines implementation. They have been developed based on the Krsko IPE (Individual Plant Examination) insights, Generic WOG SAMGs (Westinghouse Owners Group Severe Accident Management Guidances) and plant specific documents developed within this effort. Among the required plant specific actions the following are the most important ones: Identification and documentation of those Krsko plant specific severe accident management features (which also resulted from the IPE investigations). The development of the Krsko plant specific background documents (Severe Accident Plant Specific Strategies and SAMG Setpoint Calculation). Also, paper discusses effort done in the areas of NPP Krsko SAMG review (internal and external ), validation on Krsko Full Scope Simulator (Severe Accident sequences are simulated by MAAP4 in real time) and world 1st IAEA Review of Accident Management Programmes (RAMP).

A problem with levels: how to engage a diverse IPE

Directory of Open Access Journals (Sweden)

Naeem Inayatullah

2015-12-01

Full Text Available Abstract Though welcome, Cohen's call for exchange across diverse perspectives in international political economy (IPE evades the question: why have we remained unaware of or insensitive to the diversity that already exists? We follow John Hobson's claim that racism, imperialism and Eurocentrism disallow a western-dominated social science from engaging with diverse viewpoints. We argue further that a disciplinary bias towards a unit-level or atomistic understanding of social science precludes and disallows epistemological encounters in which actual diversity might be harnessed. We support this claim in two steps. First, we draw on Ghassan Hage's analysis of exigophobia, or the fear that social explanation inadvertently justifies horrendous actions and humanises their perpetrators. Exigophobia activates what we call the condemnation imperative: an eagerness to condemn an individual or group act, of fierce violence, for example, before one has tried to understand or explain it. Second, building on Nicholas Onuf's work on levels, we show that the disciplinary bias towards explanations which 'see' from the level of individual actors treats Europe or the west, in Hobson's terms, as 'self-constituting and exceptional'. When one neglects the structuring features of the whole, and assumes western 'pioneering agency', it is easy to treat non-western inferiority (irrationality, backwards culture, and so on as an explanation of the relative successes and failures of a flattened planet of autonomous units. Though we endorse forms of social explanation that start from the whole as opposed to the parts, we favour the view that there are only simultaneous and continuous processes whose seeming mystical flow our descriptions cannot but freeze. We suggest that there are no levels, simply parts and wholes in process.

Full size fuels discharged from Kori-1 PWR nuclear power plant have been subjected to postirradiation examination. The fuels under investigation were irradiated for one- to four-reactor cycles. Nondestructive examination and dismantling of the fuel assemblies have been conducted in the pool of the postirradiation examination facility (PIEF) of Korea Atomic Energy Research Institue. Subsequently nondestructive and destructive examinations of fuel rods have been performed in the hot cells of the PIEF. An evaluation of fuel burnup behaviors was based on the postirradiation examination data and the nominal design values. The results did not show any evidence of abnormalities in the fuel integrity.

Full size fuels discharged from Kori-1 PWR nuclear power plant have been subjected to postirradiation examination. The fuels under investigation were irradiated for one- to four-reactor cycles. Nondestructive examination and dismantling of the fuel assemblies have been conducted in the pool of the postirradiation examination facility (PIEF) of Korea Atomic Energy Research Institute. Subsequently nondestructive and destructive examinations of fuel rods have been performed in the hot cells of the PIEF. An evaluation of fuel burnup behaviors was based on the postirradiation examination data and the nominal design values. The results did not show any evidence of abnormalities in the fuel integrity.

Polycrystalline MoS{sub 2} grown by Mo sulphurization was exposed to increasing doses of Ar{sup +} ions at 250 eV starting from 2.2 × 10{sup 15} ions/cm{sup 2} to 3.92 × 10{sup 17} ions/cm{sup 2}. Electronic structure changes were monitored by X-Ray Photoelectron Spectroscopy (XPS) and Inverse Photolectron Spectroscopy (IPES). No change in the Fermi level position was observed with Ar{sup +} dosing. Ion bombardment resulted in a new visible feature at lower binding energy in the Mo3d core level, while the S2p lineshape showed little changes. The formation of a steady state from 2.49 × 10{sup 17} ions/cm{sup 2} has been detected. The investigation of the occupied and unoccupied states on the steady-state surface pointed to the simultaneous presence of metallic-like Mo with amorphous MoS{sub 2-x}.

Since 1970, defense transuranic waste has been placed into 20-year retrievable storage at the Radioactive Waste Management Complex at the Idaho National Engineering Laboratory (INEL). A major objective of the U.S. Department of Energy (DOE) Nuclear Waste Management Program is to remove all retrievably stored transuranic waste from the INEL. The January 1981 DOE Record of Decision on the Waste Isolation Pilot Plant (WIPP) stated, ''The WIPP facility will dispose of defense transuranic waste stored retrievably at the Idaho National Engineering Laboratory.'' After retrieval and before shipment, processing may be necessary to prepare the waste for acceptance, handling, and enhanced long-term isolation in the WIPP. However, some of the waste is certifiable to the WIPP waste acceptance criteria without container opening or waste processing. To minimize costs, the Stored Waste Examination Pilot Plant (SWEPP) is being developed to certify INEL stored transuranic waste without container opening or waste processing. The SWEPP certification concept is based on records assessment, nondestructive examination techniques, assay techniques, health physics examinations, and limited opening of containers at another facility for quality control

Ascertainment bias are common in epidemiologic studies to assess the association between thyroid cancer risk and living near nuclear power plants because many thyroid cancers are diagnosed by chance through health examination. We surveyed the ultra sonography (USG) examination history and conducted thyroid and breast USG in residents living near nuclear power plants. The study population comprised 2,421 residents living near nuclear power plants in Korea. Information on demographic characteristics, including diagnostic examination history, was collected by interview using questionnaires. USG examination was conducted to evaluate the presence of thyroid nodules and breast lesion. Study participants were divided into 3 groups according to the distance of their respective villages from a nuclear power plant. The proportions of USG examination history and prevalence of thyroid nodules and breast lesions were compared between groups. Examination histories of thyroid USG were 23.1%, 13.7%, and 10.5% in men and 31.3%, 26.7%, 18.3% in women in the short, intermediate, and long distance groups, respectively. There were significant inverse associations between thyroid USG history and the distance from nuclear power plants (P for trend=0.001 for men and 0.017 for women). However, there was no association between the distance of villages from nuclear power plants and prevalence of thyroid nodules. Our results suggest that there may be an ascertainment bias in population-based studies examining the harmful effects of NPPs examination and researchers should pay attention to ascertainment bias resulted from differential health examination. Correction for ascertainment bias, active follow-up and examination for all study population to remove differential health examination is needed.

Full Text Available BACKGROUND: Evidence is available on the potential efficacy of interprofessional education (IPE to foster interprofessional cooperation, improve professional satisfaction, and improve patient care. While the intention of the World Health Organization (WHO is to implement IPE in all countries, evidence comes from developed countries about its efficiency, challenges, and barriers to planning and implementing IPE. We therefore conducted this review to examine challenges of implementing IPE to suggest possible pathways to overcome the anticipated challenges in developing countries. METHODS: We searched for literatures on IPE in PubMed/MEDLINE, CINAHL, PsycINFO, and ERIC databases. We examined challenges or barriers and initiatives to overcome them so as to suggest methods to solve the anticipated challenges in developing countries. We could not conduct a meta-analysis because of the qualitative nature of the research question and the data; instead we conducted a meta-narrative of evidence. RESULTS: A total of 40 out of 2,146 articles were eligible for analyses in the current review. Only two articles were available from developing countries. Despite the known benefits of IPE, a total of ten challenges or barriers were common based on the retrieved evidence. They included curriculum, leadership, resources, stereotypes and attitudes, variety of students, IPE concept, teaching, enthusiasm, professional jargons, and accreditation. Out of ten, three had already been reported in developing countries: IPE curriculum, resource limitations, and stereotypes. CONCLUSION: This study found ten important challenges on implementing IPE. They are curriculum, leadership, resources, stereotypes, students' diversity, IPE concept, teaching, enthusiasm, professional jargons, and accreditation. Although only three of them are already experienced in developing countries, the remaining seven are potentially important for developing countries, too. By knowing these

IAEA team to report on Kashiwazaki Kariwa Nuclear Power Plant examination

International Nuclear Information System (INIS)

2007-01-01

Full text: The Kashiwazaki Kariwa Nuclear Power Plant in Japan, affected by a strong earthquake on 16 July, shut down safely and damage appears less than expected, a fact finding mission of international nuclear safety experts has concluded. The six member expert team of the International Atomic Energy Agency was dispatched upon the request of the Japanese authorities. The mission report will be issued within a few days. The Director General of the IAEA, Mohamed ElBaradei, said today that he welcomed the cooperation and transparency the team had received from the Japanese authorities. The mission's findings and the Japanese analyses of the event include important lessons learned - both positive and negative - that will be relevant to other nuclear plants worldwide, he said. The team conducted a three day physical examination covering the complex of seven units, as well as analysis of instrument logs and other records from the time of the event. It has concluded that plant safety features performed as required during the earthquake. The team's review of plant operator records and analyses support the Japanese authorities' conclusion that the very small amount of radioactivity released was well below the authorized limits for public health and environmental safety. Damage from the earthquake appears to be limited to those sections of the plant that would not affect the reactor or systems related to reactor safety. Detailed checks and inspections by the operator and Japanese authorities are ongoing. According to the IAEA team, significant work, such as detailed examination of the reactor vessels, cores and fuel elements, has still to be performed. Physical stresses resulting from the earthquake could affect the long term safe operation of some plant components, the team said. Additional engineering analysis of such components would be an important consideration for future examination, to determine whether they should be replaced earlier than otherwise anticipated. The

The interprofessional education (IPE) program at Gunma University, Maebashi, Japan, uses a lecture style for first-year students and a training style for third-year students. To investigate the comprehensive implications of IPE, the change pattern of attitudes toward health care teams was examined longitudinally in pre-qualified students. The modified Attitudes Toward Health Care Teams Scale (mATHCTS) was used. The overall mean score of the mATHCTS improved significantly after the training-style IPE in their third year. Two individual items in the factor "quality of care delivery" decreased significantly during the first year. In contrast, two individual items in the factor "patient-centered care" increased significantly during the third year. These changes over time were confirmed by analyses using regression factor scores. There are at least two independent attitudes toward collaborative practice (CP) or IPE in response to IPE interventions: the attitude toward "value of IPE for health care providers" may response negatively to IPE in the early stages, and the attitude toward "value of IPE for health care receivers" positively in the later stages. These findings suggest that the continuation of mandatory IPE, which must be designed on the basis of students' high expectations for IPE and CP on entry, may result in profound changes in attitudes amongst participating students.

This paper reviews recent experience in nuclear plant inservice inspection activities including ultrasonic examination of piping materials, personnel qualification, results, and the overall significance to the industry. Several areas of concern to the nuclear power industry have recently been addressed by Southern Company Services' (SCS) Inspection, Testing, and Engineering Department during implementation of preservice and in-service inspection activities in the SCS system. The most significant of these activities is the ultrasonic inspection of Type 304 stainless steel piping for the presence of intergranular stress corrosion cracking (IGSCC). This activity has been in the forefront of boiling water reactor (BWR) in-service inspections for the past several years

Examining the role of shrub expansion and fire in Arctic plant silica cycling

All terrestrial plants accumulate silica (SiO2) to some degree, although the amount varies by species type, functional group, and environmental conditions. Silica improves overall plant fitness, providing protection from a variety of biotic and abiotic stressors. Plant silica uptake serves to retain silica in terrestrial landscapes, influencing silica export rates from terrestrial to marine systems. These export rates are important because silica is often the limiting nutrient for primary production by phytoplankton in coastal waters. Understanding how terrestrial plant processes influence silica export rates to oceanic systems is of interest on the global scale, but nowhere is this issue more important than in the Arctic, where marine diatoms rely on silica for production in large numbers and terrestrial runoff largely influences marine biogeochemistry. Moreover, the rapid rate of change occurring in the Arctic makes understanding plant silica dynamics timely, although knowledge of plant silica cycling in the region is in its infancy. This work specifically examines how shrub expansion, permafrost thaw, and fire regimes influence plant silica behavior in the Alaskan Arctic. We quantified silica accumulation in above and belowground portions of three main tundra types found in the Arctic (wet sedge, moist acidic, moist non-acidic tundra) and scaled these values to estimate how shrub expansion alters plant silica accumulation rates. Results indicate that shrub expansion via warming will increase silica storage in Arctic land plants due to the higher biomass associated with shrub tundra, whereas conversion of tussock to wet sedge tundra via permafrost thaw would produce the opposite effect in the terrestrial plant BSi pool. We also examined silica behavior in plants exposed to fire, finding that post-fire growth results in elevated plant silica uptake. Such changes in the size of the terrestrial vegetation silica reservoir could have direct consequences for the rates

Several decades of work have detailed the value and goals of interprofessional education (IPE) within the health professions, defining IPE competencies and best practices. In 2013, the Liaison Committee for Medical Education (LCME) elevated IPE to a U.S. medical school accreditation standard. To examine the status of IPE within internal medicine (IM) clerkships including perspectives, curricular content, barriers, and assessment a year after the LCME standard issuance. Anonymous online survey. IM clerkship directors from each of the Clerkship Directors in Internal Medicine's 121 U.S. and Canadian member medical schools in 2014. In 2014, a section on IPE (18 items) was included in the Clerkship Directors in Internal Medicine annual survey of its 121 U.S. and Canadian member medical schools. Items (18) assessed clerkship director (CD) perspectives, status of IPE curricula in IM clerkships, and barriers to IPE implementation. Data were analyzed using descriptive statistics and qualitative analysis of free-text responses to one of the survey questions. The overall survey response rate was 78% (94/121). The majority (88%) agreed that IPE is important to the practice of IM, and 71% believed IPE should be part of the IM clerkship. Most (76%) CDs agreed there is need for faculty development programs in IPE; 27% had such a program at their institution. Lack of curricular time, scheduling conflicts, and lack of faculty trained in IPE were the most frequently cited barriers. Twenty-nine percent had formal IPE activities within their IM clerkships, and 38% were planning to make changes. Of those with formal IPE activities, over a third (37%) did not involve student assessment. Since LCME standard issuance, only a minority of IM clerkships have included formal IPE activities, with lectures as the predominant method. Opportunities exist for enhancing educational methods as well as IPE faculty development.

A study on the implementation effect of accident management strategies on safety

International Nuclear Information System (INIS)

Jae, Moo Sung; Kim, Dong Ha; Jin, Young Ho

1996-01-01

This paper presents a new approach for assessing accident management strategies using containment event trees(CETs) developed during an individual plant examination (IPE) for a reference plant (CE type, 950 MWe PWR). Various accident management strategies to reduce risk have been proposed through IPE. Three strategies for the station blackout sequence are used as an example: 1) reactor cavity flooding only, 2) primary system depressurization only, and 3) doing both. These strategies are assumed to be initiated at about the time of core uncovery. The station blackout (SBO) sequence is selected in this paper since it is identified as one of the most threatening sequences to safety of the reference plant. The effectiveness and adverse effects of each accident management strategy are considered synthetically in the CETs. A best estimate assessment for the developed CETs using data obtained from NUREG-1150, other PRA results, and the MAAP code calculations is performed. The strategies are ranked with respect to minimizing the frequencies of various containment failure modes. The proposed approach is demonstrated to be very flexible in that it can be applied to any kind of accident management strategy for any sequence. 9 refs., 3 figs., 2 tabs. (author)

The Porous Tube Plant Nutrient Delivery System (PTPNDS) was designed for NASA to grow plants in microgravity of space. The system utilizes a controlled fluid loop to supply nutrients and water to plant roots growing on a ceramic surface moistened by capiflary action. A PTPNDS test bed was developed and utilizing remote sensing systems, spectral analyses procedures, gas-exchange, and fluorescence measurements, we examined differences in plant water status for wheat plants (Triticum aestivum, cv. Perigee) grown in a modified growth chamber during the summers of 2003 and 2004. Some differences in plant performance were detectable in the gas-exchange and fluorescence measurements. For instance, in both years the plants grown with the most available water had the lowest rates of photosynthesis and exhibited higher proportions of non-photochemical quenching particularly under low light levels. In addition, small differences in mean leaf water content between treatments were detected using spectral reflectance analyses.

Interprofessional education (IPE) has been widely incorporated into health professional curricula and accreditation standards despite an arguably thin base of evidence regarding its clinical effects, theoretical underpinnings, and social implications. To better understand how and why IPE first took root, but failed to grow, this study examines one of the earliest documented IPE initiatives, which took place at the University of British Columbia between 1960 and 1975. We examined a subset of 110 texts (academic literature, grey literature, and unpublished records) from a larger study that uses Critical Discourse Analysis to trace the emergence of IPE in Canada. We asked how IPE was promoted and received, by whom, for what purposes, and to what effects. Our analysis demonstrates that IPE was promoted as a response to local challenges for the Faculty of Medicine as well as national challenges for Canada's emerging public healthcare system. These dual exigencies enabled the IPE initiative, but they shaped it in somewhat divergent ways: the former gave rise to its core component (a health sciences centre) and the latter its ultimate purpose (increasing the role of non-medical professions in primary care). Reception of the initiative was complicated by a further tension: nurses and allied health professionals were sometimes represented as independent experts with unique knowledge and skills, and sometimes as assistants or substitutes for medical doctors. We relate the successes and frustrations of this early initiative to particular (mis)alignments of purpose and relationships of power, some of which continue to enable and constrain IPE today.

Interprofessional education for first year psychology students: career plans, perceived relevance and attitudes.

2015-05-01

Undergraduate psychology students have been largely excluded from interprofessional education (IPE) initiatives. In contrast to many health professions, undergraduate psychology students do not engage in work placements as part of their degree, and many enter careers outside the health care context. However, the collaborative skills gained through an IPE experience may well be beneficial to students who work in this wider context. This research examines whether undergraduate psychology students' views of IPE vary according to their planned career directions, and if so, whether the perceived relevance of IPE mediates the relationships. A sample of 188 Australian university undergraduate psychology students completed an online questionnaire following completion of a first-year IPE health sciences program. Path analysis indicated that psychology students' attitudes towards IPE are associated with both professional identification and practitioner orientation, fully mediated through the perceived relevance of IPE to future career and study plans. Stronger professional identification and practitioner orientation were associated with greater perceived relevance and more positive and less negative attitudes towards IPE. Placing a stronger emphasis on the generalizability of IP skills taught may increase students' awareness of the relevance outside of the health context, reducing disengagement of students planning alternative careers.

The World Health Organization (WHO) and its partners identify interprofessional (IP) collaboration in education and practice as an innovative strategy that plays an important role in mitigating the global health workforce crisis. Evidence on the practice of global health level in interprofessional education (IPE) is scarce and hampered due to the absence of aggregate information. Therefore, this systematic review was conducted to examine the incidences of IPE and summarize the main features about the IPE programs in undergraduate and postgraduate education in developed and developing countries. The PubMed, Embase, Web of Science, and Google Scholar were searched from their inception to January 31, 2016 for relevant studies regarding the development of IPE worldwide, IPE undergraduate and postgraduate programs, IP interaction in health education, IPE content, clinical placements, and teaching methods. Countries in which a study was conducted were classified as developed and developing countries according to the definition by the United Nations (UN) in 2014. A total of 65 studies from 41 countries met our inclusion criteria, including 45 studies from 25 developed countries and 20 studies from 16 developing countries. Compared with developing countries, developed countries had more IPE initiatives. IPE programs were mostly at the undergraduate level. Overall, the university was the most common academic institution that provided IPE programs. The contents of the curricula were mainly designed to provide IP knowledge, skills, and values that aimed at developing IP competencies. IPE clinical placements were typically based in hospitals, community settings, or both. The didactic and interactive teaching methods varied significantly within and across universities where they conducted IPE programs. Among all health care disciplines, nursing was the discipline that conducted most of the IPE programs. This systematic review illustrated that the IPE programs vary substantially

Lee, Yoon Hwan; Park, Jin Hee; Lim, Ho Gon

2016-01-01

In 2009, the electric power research institute (EPRI) published a guideline for the development of IF-PRA that addresses the requirements of the ASME/ANS RASa-2009 PRA consensus standard. The EPRI guideline delineates a level of detail and assessment complexity that has been significantly increased with respect to the guidance for IF assessment performed for the individual plant examination (IPE) to address Generic Letter 88- 20. The main differences include: A more systematic approach to the definition of flood area. The identification, screening and analysis of flooding sources and scenarios. The calculation of the initiating-event frequency (IEF) based on the actual length and characteristics of the piping. The inclusion of spatial effects such as spray from pipe leaks. The specific documentation associated with the plant walkdowns. Among these differences, this research focused on the third and fourth items when performing the internal flooding PSA. This is done by identifying the pipe and fluid characteristics, assessing the pipe pressure, characterizing the pipe (i.e., pipe diameter, length, etc.) and determining the pressure boundary failure frequency. The results were summed for the various piping systems within a given flood area to arrive at an overall internal flood initiating frequency for a given flood mode (i.e., spray, general flood, or major flood) for that particular area by each POS (Plant Operational State). In this initiating event frequency evaluations, the POS duration time is especially considered to get the real values for LPSD state. Characterizations of spray scenarios were evaluated to determine their impact on plant risk caused by internal flooding events.

This paper investigates gamma emitter radioactivity in a system consisting of soil and plants. Some selected sample of tissues of animals fed with the plants from these sites were also measured. In soil and plant samples artificial ( 137 Cs and 134 Cs) and natural (thorium and uranium series) isotopes were detected. Despite the relatively high content of the natural isotopes in plants and their seeds, their accumulation in animal tissues was not detected.The 40 K isotope was transferred in the chain soil-plant-animal in the highest degree. From the group of the natural isotopes, only 212 Pb was detected in examined animal tissue samples. Other natural isotopes were below detection level. In the samples heavy metal content was also examined. In any sample no element concentration was noticed above trade acceptable limit. (author)

Faculty attitudes are believed to be a barrier to successful implementation of interprofessional education (IPE) initiatives within academic health sciences settings. The purpose of this study was to examine specific attributes of faculty members, which might relate to attitudes towards IPE and interprofessional teamwork. A survey was distributed to all faculty members in the medicine, nursing, pharmacy and social work programmes at our institution. Respondents were asked to rate their attitudes towards interprofessional health care teams, IPE and interprofessional learning in an academic setting using scales adopted from the peer-reviewed literature. Information on the characteristics of the respondents was also collected, including data on gender, prior experience with IPE, age and years of practice experience. A total response rate of 63.0% was achieved. Medicine faculty members reported significantly lower mean scores (P nursing faculty on attitudes towards IPE, interprofessional teams and interprofessional learning in the academic setting. Female faculty and faculty who reported prior experience in IPE reported significantly higher mean scores (P teamwork. The findings have implications for both the advancement of IPE within academic institutions and strategies to promote faculty development initiatives. In terms of IPE evaluation, the findings also highlight the importance of measuring baseline attitudinal constructs as part of systematic evaluative activities when introducing new IPE initiatives within academic settings.

Full Text Available Though much has been written on Interprofessional Education (IPE and Faculty Learning Communities (FLCs independently, there is limited literature devoted to examining the use of FLCs to enhance IPE for the health professions. A FLC dedicated to building capacity for IPE in a small, private midwestern university comprised of faculty representing occupational therapy, physical therapy, nursing, public health, gerontology, medical anthropology, psychology, social work, and exercise science was conducted over the course of one semester. This article details the implementation process for the IPE FLC; describes outcomes related to teaching, scholarship, and service of faculty from a qualitative evaluation conducted 18 months after the completion of the FLC; and concludes with a discussion based on lessons learned from the process and experience of conducting an IPE FLC.

Full Text Available Purpose: As the United States health care model progresses towards medical teams and the country’s population continues to diversify, the need for health professional education programs to develop and implement culturally specific interprofessional education (IPE becomes increasingly imperative. A wide range of models exists for delivering and implementing IPE in health education, but none have included the cultural components that are vital in educating the health professional. Methods: A cross-cultural decentralized IPE model for physician assistant (PA and physical therapy (PT students was developed. This three-part IPE series was created using an established cultural curricular model and began with the exploration of self, continued with the examination of various dimensions of culture, and concluded with the exploration of the intersection between health and culture. We assessed student satisfaction of the IPE experiences and students’ engagement and attitudes towards IPE using a three-item open-ended questionnaire administered after each cross-cultural activity and the Interprofessional Education Series Survey (IESS upon the completion of the series. Results: IESS responses showed that PA and PT students reported benefits in interprofessional collaboration and cultural awareness and expressed overall satisfaction with the series. Qualitative analysis revealed growth in student response depth consistent with the scaffolded focus of each IPE module in the series. Conclusion: The trends in this three-part series suggest that institutions looking to develop culturally inclusive IPE educational initiatives may have success through a decentralized model mirroring the effective cultural progression focused on addressing exploration of self, examination of various dimensions of culture, and exploration of the intersection between health and culture.

Rubber (Hevea brasiliensis) plants derived from anther and ovule culture as well as gamma-irradiated plants were examined by several DNA marker techniques. These include restriction fragment length polymorphisms (RFLPs), random amplified polymorphic DNA (RAPD), sequence tagged microsatellite sites (STMS), DNA amplification fingerprinting (DAF) and amplified fragment length polymorphisms (AFLPs). Compared to control plants produced by vegetative propagation (cutting and budding), plants produced by in vitro culture appeared to have a reduction in the number of rDNA loci. Two RAPD protocols were compared and found to be similar in amplification of the major DNA bands. After confirmation that the RAPD method adopted was reproducible, the technique was applied to the present studies. Eight out of the 60 primers screened were able to elicit polymorphisms between pooled DNA from in vitro culture plants. Variations in DNA patterns were observed between pooled DNA samples of anther-derived plants as well as between anther-derived and ovule-derived plants. Comparisons of RAPD patterns obtained between anther-derived plants exposed to increasing dosages of gamma-irradiation with non irradiated anther-derived plants revealed distinct DNA polymorphisms. The changes in DNA profiles did not appear to be correlated to the dosage of irradiation. Since somaclonal variation was detected, it was difficult to identify changes which were specifically caused by irradiation. Application of the STMS technique to tag micro satellite sequences (GA) n , (TA) n and (TTA) n in the hydroxymethylglutaryl coenzyme A reductase-1 (hmgr-1) gene failed to detect differences between plants derived from anther and ovule culture. Although restriction endonuclease digestions with methylation sensitive enzymes suggested that four in vitro culture plants examined exhibited similar digestion patterns as the controls, a change in cytosine methylation in one anther-derived plant was detected.

Individual plant examinations (IPE) are being performed by utilities to evaluate plant-specific vulnerabilities to severe accidents. A major tool in performing an IPE is a probabilistic risk assessment (PRA). The importance of human interactions in determining the plant response in past PRAs is well documented. The modeling and quantification of the probabilities of human interactions have been the subjects of considerable research by the Electric Power Research Institute (EPRI). A revised framework, SHARP1, for incorporating human interactions into PRA is summarized in this report. SHARP1 emphasizes that the process stages are iterative and directed at specific goals rather than being performed sequentially in a stepwise procedure. This expanded summary provides the reader with a flavor of the full report content. Excerpts from the full report are presented, following the same outline as the full report. In the full report, the interface of the human reliability analysis with the plant logic model development in a PRA is given special attention. In addition to describing a methodology framework, the report also discusses the types of human interactions to be evaluated, and how to formulate a project team to perform the human reliability analysis. A concise description and comparative evaluation of the selected existing methods of quantification of human error are also presented. Four case studies are also provided to illustrate the SHARP1 process

Ultrasound testing performance during in-service inspection for the main components of NPPs is strongly affected by each examination person. Therefore, ASME established a more strict qualification requirement in Sec. XI Appendix VIII for the ultrasound testing personnel in nuclear power plants. The Korean Performance Demonstration (KPD) System according to the ASME code for the ultrasonic testing personnel, equipments, and procedures to apply to the Class 1 and 2 piping ultrasound examination of nuclear power plants in Korea was established. And a round robin test was conducted in order to verify the effectiveness of PD method by comparing the examination results from the method of Performance Demonstration (PD) and a traditional ASME code dB-drop method. The round robin test shows that the reliability of the PD method is better than that of the dB-drop method. As a result, application of the PD method to the in-service inspection of the nuclear power plants will improve the performance of ultrasound testing

Interprofessional education (IPE) provides students with opportunities to learn about the roles and responsibilities of other professions and develop communication and teamwork skills. As different health professions have recognised the importance of IPE, the number of disciplines participating in IPE events is increasing. Consequently, it is important to examine the effect group structure has on the learning environment and student knowledge acquisition during IPE events. The purpose of this study was to determine the effect of group composition on student perceptions of interprofessional teamwork and collaboration when participating in a case-based IPE forum. To examine this construct, six cohorts of students were divided into two groups: Group-one (2010-2012) included students from five professions. Group-two (2013-2015) included students from 10 professions. The only other change for group-two was broadening the case scenarios to ensure a role for each profession. At the conclusion of the case-based IPE forums, both groups demonstrated a statistically significant increase in 'readiness for interprofessional learning' and 'interdisciplinary education perceptions'. However, participants in group-one (2010-2012) demonstrated a greater change in scores when compared to group-two (2013-2015). It was concluded a case-based IPE forum with students from numerous health professions participating in a discussion about broad case scenarios was moderately effective at introducing students to other health professions and increasing their knowledge of others' identities. However, a smaller grouping of professions with targeted cases was more effective at influencing student perceptions of the need for teamwork. When planning an IPE event, faculty should focus on intentional groupings of professions to reflect the social context of healthcare teams so all students can fully participate and experience shared learning.

This paper describes the assessment of the work structure of ten nuclear power plants. Work structure factors are those factors that relate to the way in which work at all levels in a plant is organized, staffed, managed, rewarded, and perceived by plant personnel. Questionnaires given to a cross-section of personnel at the plants were the primary source of data collection. Structured ''critical incident'' interviews were conducted to verify the questionnaire results. The study revealed that a variety of work structure factor problem areas do exist in nuclear power plants. The paper highlights a prioritized set of candidate research themes to be considered in EPRI's Work Structure and Performance Research Program

The attitudes of faculty towards interprofessional education (IPE) and teamwork impact the education of health professions education (HPE) students. This paper reports on a study evaluating attitudes from health professions educators towards IPE and teamwork at one academic health science center (HSC) where modest IPE initiatives have commenced. Drawing from the results of a previous investigation, this study was conducted to examine current attitudes of the faculty responsible for the training of future healthcare professionals. Survey data were collected to evaluate attitudes from HSC faculty, dentistry, nursing, medicine, pharmacy and public health. In general, positive HSC faculty attitudes towards interprofessional learning, education, and teamwork were significantly predicted by those affiliated with the component of nursing. Faculty development aimed at changing attitudes and increasing understanding of IPE and teamwork are critical. Results of this study serve as an underpinning to leverage strengths and evaluate weakness in initiating IPE.

Today interprofessional education (IPE) is spread throughout the world. In Sweden only one of the existing nursing programs has an IPE curriculum on several levels during the training. The aim of this study was to examine how nurses who recently graduated from universities with IPE or non-IPE curricula perceive the importance of different educational goals and whether they found themselves prepared for their profession, and especially for collaboration with other professions. Three universities with different commitments to IPE were studied. We used a survey with eight different targets: communication skills, cooperation with other professions, problem-solving capability, self-directed learning skills, whether their education has prepared them to work professionally, to perform research, to take care of acutely ill patients, to work preventively and working as a nurse. The participants were asked whether their undergraduate education had prepared them for these targets and whether they perceived that the targets were important goals for their education. A main result in this study was that nurses who had recently graduated from the IPE university perceived to a greater extent that their undergraduate training had prepared them to work together with other professions in comparison with nursing students from non-IPE universities.

Given the emphasis on prevention in U.S. health care reform efforts, the importance of interprofessional education (IPE) that prepares health professions students to be part of effective health care teams is greater than ever. This study examined the prevalence and nature of IPE and interprofessional (IP) prevention education in U.S. academic health centers. The authors extracted a 10-item survey from the longer published IPE Assessment and Planning Instrument. In September 2010, they sent the survey to 346 health professions leaders in health sciences schools and colleges at 100 academic health centers. These institutions were identified via the online membership list of the Association of Academic Health Centers. The authors conducted descriptive statistical analysis and cross-tabulations. Surveys were completed by 127 contacts at 68 universities in 31 states and the District of Columbia. IPE was more prevalent than IP prevention education in all categories of measurement. Respondents affirmed existence of IPE in courses (85.0%) and in clinical rotations/internships (80.3%). The majority reported personnel with responsibility for IPE (68.5%) or prevention education (59.8%) at their institutional unit, and 59.8% reported an IPE office or center. This study provides evidence that IPE and IP prevention education exist in academic health centers, but additional attention should be paid to the development of IP prevention education. Sample syllabi, job descriptions, and policies may be available to support adoption of IPE and IP prevention education. Further effort is needed to increase the integration of IP and prevention education into practice.

The aim of this study was to investigate the feasibility of utilizing different lignocellulosic hydrolysates with various hexose versus pentose (H:P) ratios to produce lactic acid (LA) from Bacillus coagulans IPE22 by fermentations with single and mixed sugar. In single sugar utilization, glucose tended to promote LA production, and xylose preferred to enhance cell growth. In mixed sugar utilization, glucose and pentose were consumed simultaneously when glucose concentration was lower than 20 g/L, and almost the same concentration of LA (50 g/L) was obtained regardless of the differences of H:P values. Finally, LA production from corn cob hydrolysates (CCH) contained 60 g/L mixed sugar verified the mechanisms found in the fermentations with simulated sugar mixture. Comparing with single glucose utilization, CCH utilization was faster and the yield of LA was not significantly affected. Therefore, the great potential of producing LA with lignocellulosic materials by B. coagulans was proved. Copyright © 2018. Published by Elsevier Ltd.

This paper presents the results of a literature survey that examined radionuclide emissions from coal-fired power plants. Literature references from both the US and foreign countries are presented. Emphasis is placed on references from the US because the radionuclide emissions from coal-fired power plants are related to radionuclide concentrations in the coal, which vary widely throughout the world. The radionuclides were identified and quantified for various existing power plants reported in the literature. Applicable radionuclide emissions criteria discovered in the literature search were then applied to a proposed circulating fluidized bed boiler power plant. Based upon the derived radionuclide emission rates applied to the proposed power plant, an air quality modeling analysis was performed. The estimated ambient concentrations were compared to the most relevant existing regulatory ambient levels for radionuclides

There are significant limitations among the few prior studies that have examined the development and implementation of interprofessional education (IPE) experiences to accommodate a high volume of students from several disciplines and from different institutions. The present study addressed these gaps by seeking to determine the extent to which a single, large, inter-institutional, and IPE simulation event improves student perceptions of the importance and relevance of IPE and simulation as a learning modality, whether there is a difference in students' perceptions among disciplines, and whether the results are reproducible. A total of 290 medical, nursing, pharmacy, and physical therapy students participated in one of two large, inter-institutional, IPE simulation events. Measurements included student perceptions about their simulation experience using the Attitude Towards Teamwork in Training Undergoing Designed Educational Simulation (ATTITUDES) Questionnaire and open-ended questions related to teamwork and communication. Results demonstrated a statistically significant improvement across all ATTITUDES subscales, while time management, role confusion, collaboration, and mutual support emerged as significant themes. Results of the present study indicate that a single IPE simulation event can reproducibly result in significant and educationally meaningful improvements in student perceptions towards teamwork, IPE, and simulation as a learning modality.

2014-04-01

It is critical to prepare nurses for future practice to work in teams by engaging students in interprofessional education (IPE) that fosters positive attitudes toward teamwork. The purpose of this study was to examine the effects of computer-supported IPE on students’ attitudes and perceptions toward health care teamwork and team performance. A hybrid approach to IPE was used to provide students with an educational experience that combined the benefits of traditional face-to-face communication methodology with a computer-mediated platform that focused on reflection and team building. A statistically significant difference was found in students’ perceptions of team performance after engaging in computer-supported IPE. No statistically significant difference in students’ pretest–posttest composite attitude toward teamwork scores was noted; however, there was a positive trend toward improved scores.

Full Text Available Interprofessional education (IPE is considered to be a way to introduce health profession students on the importance of teamwork in providing excellent healthcare services. There has been no report that explores students’ perception toward IPE before implementation of the program. This study aimed to examine the factors that might affect students’ attitude towards IPE and explore the underlying reasons of their attitude. The population of this study was students of final year of preclinical program of Medicine, nursing, dentistry and midwifery of Sultan Agung Islamic University (Unissula Indonesia. Attitudes towards IPE were collected by questionnaire adapted from RIPL which has been validated with alpha Cronbach 0.885. The quantitative data were analyzed using multivariate logistic regression. Uni-profession FGs were conducted to explore the underlying reason of students’ attitude toward IPE. Qualitative data were evaluated by two experts in medical education with the help of ATLAS Ti software. The data were evaluated from 389 students. Of this total, 210 (52.8 % of them had RIPL score low–moderate. Students’ health professional program (RR=15.99 CI95%=6.18-41.43,p= 0.000 and GPA (RR=2.76 CI95%= 1.54-4.92 p=0.001 were the most dominant variable of the readiness to IPE. Qualitative data revealed that motivation to enhance knowledge and clinical skills and desire to discuss the roles and responsibilities of each profession were the main reasons for students’ approval to IPE. Conversely a lack of confidence and role blurring were the reasons for rejecting IPE program.

The Systems Analysis Programs for Hands-on Integrated Reliability Evaluations (SAPHIRE) refers to a set of several microcomputer programs that were developed to create and analyze probabilistic risk assessments (PRAs), primarily for nuclear power plants. The primary function of MAR-D is to create a data repository for completed PRAs and Individual Plant Examinations (IPEs) by providing input, conversion, and output capabilities for data used by IRRAS, SARA, SETS, and FRANTIC software. As probabilistic risk assessments and individual plant examinations are submitted to the NRC for review, MAR-D can be used to convert the models and results from the study for use with IRRAS and SARA. Then, these data can be easily accessed by future studies and will be in a form that will enhance the analysis process. This reference manual provides an overview of the functions available within MAR-D and step-by-step operating instructions

Nuclear power and probabilistic safety assessment (PSA): past through future applications

Stamatelatos, M. G.; Moieni, P.; Everline, C. J.

1995-03-01

Nuclear power reactor safety in the United States is about to enter a new era -- an era of risk- based management and risk-based regulation. First, there was the age of `prescribed safety assessment,' during which a series of design-basis accidents in eight categories of severity, or classes, were postulated and analyzed. Toward the end of that era, it was recognized that `Class 9,' or `beyond design basis,' accidents would need special attention because of the potentially severe health and financial consequences of these accidents. The accident at Three Mile Island showed that sequences of low-consequence, high-frequency events and human errors can be much more risk dominant than the Class 9 accidents. A different form of safety assessment, PSA, emerged and began to gain ground against the deterministic safety establishment. Eventually, this led to the current regulatory requirements for individual plant examinations (IPEs). The IPEs can serve as a basis for risk-based regulation and management, a concept that may ultimately transform the U.S. regulatory process from its traditional deterministic foundations to a process predicated upon PSA. Beyond the possibility of a regulatory environment predicated upon PSA lies the possibility of using PSA as the foundation for managing daily nuclear power plant operations.

Lake Ipe, located in a floodplain area of Parana River, is an ecosystem that apparently does not show signs of pollution. The samplings of sediments in this lake, with a surface area of approximately 10,700 m 2 , were taken at the central point. The soil samples were gathered in a terrestrial area close to the lake not exposed to inundation by overflowing. The qualitative determinations of the main metals, Mg to Pb in soils and sediments were performed by EDXRF. The comparative study among peaks areas analysis of metals by EDXRF in soils and sediments indicated that the concentration of Fe, Zn, and Ga in sediments were respectively 3.29, 4.32, and 7.04 times higher than the soils. On the other hand, the concentrations of Rb and Pb were 100 and 1,552 times higher in sediments. The peak areas of K, Co, Ni, and Cu in sediments were practically twice in the soil samples. The peak areas of Ca, Ti, Cr, and Mn were equivalents in both compartments. The absence of Pb in soils, and the high concentrations observed in sediments, indicated that Pb came from allochthonous sources carried by water of Parana River and not by lixiviation of adjacent soils.

Objective This paper examines the implementation and implications of four development and research initiatives, collectively titled the Curriculum Renewal Studies program (CRS), occurring over a 6-year period ending in 2015 and focusing on interprofessional education (IPE) within Australian pre-registration health professional education. Methods The CRS was developed as an action-focused and participatory program of studies. This research and development program used a mixed-methods approach. Structured survey, interviews and extensive documentary analyses were supplemented by semi-structured interviews, focus groups, large group consultations and consensus building methods. Narrative accounts of participants' experiences and an approach to the future development of Australian IPE were developed. Results Detailed accounts of existing Australian IPE curricula and educational activity were developed. These accounts were published and used in several settings to support curriculum and national workforce development. Reflective activities engaging with the findings facilitated the development of a national approach to the future development of Australian IPE - a national approach focused on coordinated and collective governance and development. Conclusion This paper outlines the design of an innovative approach to national IPE governance and development. It explores how ideas drawn from sociocultural theories were used to guide the choice of methods and to enrich data analysis. Finally, the paper reflects on the implications of CRS findings for health professional education, workforce development and the future of Australian IPE. What is known about the topic? IPE to enable the achievement of interprofessional and collaborative practice capabilities is widely accepted and promoted. However, many problems exist in embedding and sustaining IPE as a system-wide element of health professional education. How these implementation problems can be successfully addressed is a

While there is extensive research examining the outcomes of interprofessional education (IPE) for students, minimal research has investigated how facilitating student learning influences the facilitators themselves. This exploratory case study aimed to explore whether and how facilitating IPE influences facilitators' own collaborative practice attitudes, knowledge, and workplace behaviours. Sixteen facilitators of an online pre-licensure IPE unit for an Australian university participated in semi-structured telephone interviews. Inductive thematic analysis revealed three emergent themes and associated subthemes characterising participants' reflexivity as IPE facilitators: interprofessional learning; professional behaviour change; and collaborative practice expertise. Participants experienced interprofessional learning in their role as facilitators, improving their understanding of other professionals' roles, theoretical and empirical knowledge underlying collaborative practice, and the use and value of online communication. Participants also reported having changed several professional behaviours, including improved interprofessional collaboration with colleagues, a change in care plan focus, a less didactic approach to supervising students and staff, and greater enthusiasm impressing the value of collaborative practice on placement students. Participants reported having acquired their prior interprofessional collaboration expertise via professional experience rather than formal learning opportunities and believed access to formal IPE as learners would aid their continuing professional development. Overall, the outcomes of the IPE experience extended past the intended audience of the student learners and positively impacted on the facilitators as well.

2003-01-01

The explicit consideration of different pressurization rates in estimating the probabilities of containment failure modes has a profound effect on the confidence of containment performance evaluation that is so critical for risk assessment of nuclear power plants. Except for the sophisticated NUREG-1150 study, many of the recent containment performance analyses (through level 2 PSAs or IPE back-end analyses) did not take into account an explicit distinction between slow and fast pressurization in their analyses. A careful investigation of both approaches shows that many of the approaches adopted in the recent containment performance analyses exactly correspond to the NUREG-1150 approach for the prediction of containment failure mode probabilities in the presence of fast pressurization. As a result, it was expected that the existing containment performance analysis results would be subjected to greater or less conservatism in light of the ultimate failure mode of the containment. The main purpose of this paper is to assess potential conservatism of a plant-specific containment performance analysis result in light of containment failure mode probabilities

Examining strategies to facilitate vitamin B1 biofortification of plants by genetic engineering

Directory of Open Access Journals (Sweden)

Lucille ePourcel

2013-05-01

Full Text Available Thiamin (vitamin B1 is made by plants and microorganisms but is an essential micronutrient in the human diet. All organisms require it as a cofactor in its form as thiamin pyrophosphate (TPP for the activity of key enzymes of central metabolism. In humans, deficiency is widespread particularly in populations where polished rice is a major component of the diet. Considerable progress has been made on the elucidation of the biosynthesis pathway within the last few years enabling concrete strategies for biofortification purposes to be devised, with a particular focus here on genetic engineering. Furthermore, the vitamin has been shown to play a role in both abiotic and biotic stress responses. The precursors for de novo biosynthesis of thiamin differ between microorganisms and plants. Bacteria use intermediates derived from purine and isoprenoid biosynthesis, whereas the pathway in yeast involves the use of compounds from the vitamin B3 and B6 groups. Plants on the other hand use a combination of the bacterial and yeast pathways and there is subcellular partitioning of the biosynthesis steps. Specifically, thiamin biosynthesis occurs in the chloroplast of plants through the separate formation of the pyrimidine and thiazole moieties, which are then coupled to form thiamin monophosphate (TMP. Phosphorylation of thiamin to form TPP occurs in the cytosol. Therefore, thiamin (or TMP must be exported from the chloroplast to the cytosol for the latter step to be executed. The regulation of biosynthesis is mediated through riboswitches, where binding of the product TPP to the pre-mRNA of a biosynthetic gene modulates expression. Here we examine and hypothesize on genetic engineering approaches attempting to increase the thiamin content employing knowledge gained with the model plant Arabidopsis thaliana. We will discuss the regulatory steps that need to be taken into consideration and can be used a prerequisite for devising such strategies in crop plants.

NPP Krsko Living PSA Concept

Vrbanic, I.; Spiler, J.

2000-01-01

NPP Krsko developed PSA model of internal and external initiators within the frame of the Individual Plant Examination (IPE) project. Within this project PSA model was used to examine the existing plant design features. In order to continue with use of this PSA model upon the completion of IPE in various risk-informed applications in support of plant operation and evaluations of design changes, an appropriate living PSA concept needed to be defined. The Living PSA concept is in NPP Krsko considered as being a set of activities pursued in order to update existing PSA model in a manner that it appropriately represents the plant design, operation practice and history. Only a PSA model which is being updated in this manner can serve as a platform for plant-specific risk informed applications. The NPP Krsko living PSA concept is based on the following major ponts. First, the baseline PSA model is defined, which is to be maintained and updated and which is to be reference point for any risk-informed application. Second, issues having a potential for impact on baseline PSA model are identified and procedure and responsibilities for their permanent monitoring and evaluation are established. Third, manner is defined in which consequential changes to baseline PSA model are implemented and controlled, together with associated responsibilities. Finally, the process is defined by which the existing version of baseline PSA model is superseded by a new one. Each time a new version of baseline PSA model is released, it would be re-quantified and the results evaluated and interpreted. By documenting these re-quantifications and evaluations of results in a sequence, the track is being kept of changes in long-term averaged risk perspective, represented by long-term averaged frequencies of core damage and pre-defined release categories. These major topics of NPP Krsko living PSA concept are presented and discussed in the paper. (author)

Public health as a catalyst for interprofessional education on a health sciences campus.

Although interprofessional education (IPE) has existed in various formats for several decades, the need for IPE recently has taken on renewed interest and momentum. Public health has a critical role to play in furthering IPE, yet schools of public health are often underrepresented in IPE initiatives. The University of Iowa College of Public Health is serving as a catalyst for IPE activities on our health sciences campus, which includes colleges of dentistry, medicine, nursing, pharmacy, and public health. IPE-related activities have included campus visit by IPE leaders, administration of the Survey of Critical Elements for Implementing IPE, administration of the Interprofessional Learning Opportunities Inventory survey, the development of a comprehensive strategic plan, and the pilot of an IPE course for all first-year prelicensure students and Master of Health Administration students. Although more work is needed to more fully integrate IPE into the curriculum, success to date of the University of Iowa IPE initiative demonstrates that public health can play a critical role as a convener and catalyst for IPE curricular innovations on a health sciences campus.

2004-01-01

A time-dependent model of the Byron Nuclear Generation Station safety-related cooling towers has been developed for use with the Byron PRA (IPE). The model can either be run in a stand-alone program with externally supplied heat loads, or can be directly coupled into MAAP (Modular Accident Analysis Program). The primary feature of the model is a careful tracking of the basin temperature through the progression of different severe accidents. Heat removal rates from containment, both from containment fan-coolers and the residual heat removal system, are determined by the feed-back of this time-varying return temperature. Also, the inventory of the basin is tracked in time, and this is controlled by make-up, evaporative losses due to the heat load supplied to the towers, and the possibility of unsecured blowdown. The model has been used to determine the overall capabilities and vulnerabilities of the Byron Ultimate Heat Sink (UHS). It was determined that the UHS is very reliable with respect to maintaining acceptably low basin temperatures, requiring only at most two of eight operating cooling tower fans. Further, when the two units have their Essential Service Water (ESW) systems cross-tied, one of four ESW operating pumps is sufficient to handle the loads from the accident unit with the other unit proceeding to an orderly shutdown. The major vulnerability of the Byron UHS is shown to be the ability to maintain inventory, although the time-scales for basin dry-out are relatively long, being eight to twenty-one hours, depending upon when blowdown is secured.

As more educators are involved in interprofessional education (IPE) it is important to consider how participation affects those who are sceptical about IPE. We report a prospective study in which the attitudes of 13 educators, unfamiliar with IPE, were compared before and after facilitating their first IPE. Their views, obtained as personal stories, were analysed through cognitive dissonance theory. Prior to teaching, all novice educators had concerns about IPE. Post-facilitation all were more positive about the value and meaning of IPE.

2010-01-01

There has been limited research on the effect of interprofessional education (IPE) over time on the attitudes of undergraduate health and human service professional students. Previous research in this area has suggested that students from different professions report differing attitudes towards IPE and interprofessional teamwork, and such attitudes may also be influenced by other background characteristics of the students themselves (e.g., gender, age). The purpose of this study was to evaluate the longitudinal effect of the introduction of an IPE curriculum on students' attitudes towards IPE and teamwork. A time series study design was conducted to assess the attitudes of undergraduate health and human service professional students towards IPE and teamwork, and students were also asked to complete satisfaction surveys after IPE curriculum activities. Significant differences in the attitudes of students from different professions and their satisfaction with participation in IPE were reported over the duration of the study. Overall, student satisfaction with IPE participation was relatively positive; however the introduction of IPE curriculum during their undergraduate education did not appear to have a significant longitudinal effect on attitudes towards IPE or interprofessional teamwork. The findings have implications for the design and integration of IPE curriculum within existing uni-professional curriculum.

The use of online media to deliver interprofessional education (IPE) is becoming more prevalent across health professions education settings. Facilitation of IPE activities is known to be critical to the effective delivery of IPE, however, specifics about the nature of online IPE facilitation remains unclear. To explore the health professions education literature to understand the extent, range and nature of research on online IPE facilitation. Scoping review methodology was used to guide a search of four electronic databases for relevant papers. Of the 2095 abstracts initially identified, after screening of both abstracts and full-text papers, 10 studies were selected for inclusion in this review. Following abstraction of key information from each study, a thematic analysis was undertaken. Three key themes emerged to describe the nature of the IPE facilitation literature: (1) types of online IPE facilitation contributions, (2) the experience of online IPE facilitation and (3) personal outcomes of online IPE facilitation. These IPE facilitation themes were particularly focused on facilitation of interprofessional student teams on an asynchronous basis. While the included studies provide some insight into the nature of online IPE facilitation, future research is needed to better understand facilitator contributions, and the facilitation experience and associated outcomes, both relating to synchronous and asynchronous online environments.

Earth's inner magnetosphere is a complex dynamical region of geo space comprising plasma populations with wide energy ranges, the plasmasphere, ring current, and radiation belts. They form a closely coupled system, thus, the plasmasphere is the lowest energy population in the inner magnetosphere, but the accurate prediction of the evolution of the plasmasphere is critical in understanding the dynamics of the inner magnetosphere, which include even the highest energy population, the radiation belts. In this study, we study plasmaspheric refilling following geomagnetic storms using data from ERG-MGF, ERG-PWE, RBSP-EMFISIS and Ground-based magneto­meters. DC magnetic field data measured by ERG-MGF, RBSP-EMFISIS and ground-based magnetometers provides the frequency of the toroidal mode field line resonances. From this information, the equatorial plasma mass density is estimated by solving the MHD wave equation for suitable models of the magnetic field and the field line density distribution. ERG-PWE and RBSP-EMFISIS provide measurements of wave electric and magnetic field, thus we can estimate the local electron density from the plasma wave spectrograms by identifying narrow-band emission at the upper-hybrid resonance frequency. Furthermore, using Ionosphere Plasmasphere Electrodynamics Model (IPE), we calculate the plasmaspheric refilling rates and evaluate the relative contribution of various mechanisms (heating, neutral particle density, composition and wings, etc.) to the refilling rate.

To identify differences among faculty members in various health professional training programs in perceived benefits and challenges of implementing interprofessional education (IPE). A 19-item survey using a 5-point Likert scale was administered to faculty members across different health disciplines at a west coast, multicollege university with osteopathic medicine, pharmacy, and physician assistant programs. Sixty-two of 103 surveys (60.2%) were included in the study. Faculty members generally agreed that there were benefits of IPE on patient outcomes and that implementing IPE was feasible. However, group differences existed in belief that IPE improves care efficiency (p=0.001) and promotes team-based learning (p=0.001). Program divergence was also seen in frequency of stressing importance of IPE (p=0.009), preference for more IPE opportunities (p=0.041), and support (p=0.002) within respective college for IPE. Despite consensus among faculty members from 3 disciplines that IPE is invaluable to their curricula and training of health care students, important program level differences existed that would likely need to be addressed in advance IPE initiatives.

Final examination of trainees for nuclear power plant operators at an education and training centre

Gieci, A.

1986-01-01

General and specialized theoretical training, on-the-job training in the training power plant and simulator training is followed by a final examination. The examination which is obligatory for all trainees is conceived according to Hick's law which requires linear dependence between the time which the operator needs for taking a decision on how to cope with a certain situation and the measure of entropy of the situation. Research in the field of man-machine relations has helped clarify the thinking of the operator who on the basis of received signals forms what is termed the conceptual model of the situation. The final examination should assess the trainee's ability to form conceptual models - the examination must therefore be something more than just a test of knowledge. The given questions and required answers must create a stress situation for the examinee such that the measure to which he is able to cope is conditioned by his ability to form conceptual models. The statutes of the final examinations were drawn up with the aim of achieving standardization and reproducibility. Questions are put through a special form (a model form is also given). (A.K.)

Interprofessional practice is recognised as an important element of safe and effective healthcare. However, few studies exist that evaluate how preregistration education contributes to interprofessional competencies, and how these competencies develop throughout the early years of a health professional's career. This quasiexperimental study will gather longitudinal data during students' last year of preregistration training and their first 3 years of professional practice to evaluate the ongoing development of interprofessional competencies and the influence that preregistration education including an explicit interprofessional education (IPE) programme may have on these. Participants are students and graduates from the disciplines of dentistry, dietetics, medicine, nursing, occupational therapy, oral health, pharmacy and physiotherapy recruited before their final year of study. A subset of these students attended a 5-week IPE immersion programme during their final year of training. All data will be collected via five written or electronic surveys completed at 12-month intervals. Each survey will contain the Attitudes Towards Health Care Teams Scale and the Team Skills Scale, as well as quantitative and free-text items to explore vocational satisfaction, career trajectories and influences on these. Students who attend the IPE programme will complete additional free-text items to explore the effects of this programme on their careers. Quantitative analysis will compare scores at each time point, adjusted for baseline scores, for graduates who did and did not participate in the IPE programme. Associations between satisfaction data and discipline, professional setting, location and IPE participation will also be examined. Template analysis will explore free-text themes related to influences on career choices including participation in preregistration IPE. This study has received approval from the University of Otago Ethics Committee (D13/019). Results will be

Exploring the social lives of image and performance enhancing drugs: An online ethnography of the Zyzz fandom of recreational bodybuilders.

Underwood, Mair

2017-01-01

As a result of the mainstreaming of bodybuilding, the majority of image and performance enhancing drug (IPED) users are now not athletes or competitive bodybuilders, but recreational bodybuilders. Previous approaches provide little insight into how the shift from competitive to recreational contexts impacts the use of IPEDs. In this study an online ethnographic approach is used to explore the social lives of IPEDs in a recreational context. The study focusses on the Zyzz fandom, an international online community of thousands of recreational bodybuilders who idolise the alleged IPED user Zyzz. Zyzz fans see IPED prohibition as failing, as causing harm to users, and as sexist. Their IPED use is informed by not only instrumental benefits, but social benefits such as altering gendered power relations. IPEDs have been normalised in this community, and new patterns of use are emerging. IPEDS have moved through different hands, contexts and uses, and in so doing the values, norms and meanings attached to IPEDs have changed. The results suggest that intervention efforts may be best directed towards harm minimisation, and in particular towards bridging the divides between the medical and bodybuilding communities.

Xylella fastidiosa is a Gram-negative bacterial plant pathogen with an extremely wide host range. This species has recently been resolved into subspecies that correlate with host specificity. This review focuses on the status of X. fastidiosa pathogenic associations in plant hosts in which the bacterium is either endemic or has been recently introduced. Plant diseases associated with X. fastidiosa have been documented for over a century, and much about what is known in the context of host-pathogen interactions is based on these hosts, such as grape and citrus, in which this pathogen has been well described. Recent attention has focused on newly emerging X. fastidiosa diseases, such as in olives. Bacteria; Gammaproteobacteria; family Xanthomonadaceae; genus Xylella; species fastidiosa. Gram-negative rod (0.25-0.35 × 0.9-3.5 μm), non-flagellate, motile via Type IV pili-mediated twitching, fastidious. Xylella fastidiosa has a broad host range that includes ornamental, ecological and agricultural plants belonging to over 300 different species in 63 different families. To date, X. fastidiosa has been found to be pathogenic in over 100 plant species. In addition, it can establish non-symptomatic associations with many plants as a commensal endophyte. Here, we list the four distinct subspecies of X. fastidiosa and some of the agriculturally relevant diseases caused by them: X. fastidiosa ssp. fastidiosa causes Pierce's disease (PD) of grapevine (Vitis vinifera); X. fastidiosa ssp. multiplex causes almond leaf scorch (ALS) and diseases on other nut and shade tree crops; X. fastidiosa ssp. pauca causes citrus variegated chlorosis (CVC) (Citrus spp.), coffee leaf scorch and olive quick decline syndrome (OQDS) (Olea europaea); X. fastidiosa ssp. sandyi causes oleander leaf scorch (OLS) (Nerium oleander). Significant host specificity seemingly exists for some of the subspecies, although this could be a result of technical biases based on the limited number of

Interprofessional education (IPE) was investigated in the context of an evaluation of the Advanced Life Support in Obstetrics (ALSO) course in Australia. Our objectives were to examine doctors' and midwives' perceptions regarding interprofessional learning and measure changes in self-reported confidence in specific interprofessional clinical situations. A prospective, mixed methods design was used to survey 165 ALSO course participants before the course and 6 weeks after the course (n=101). Quantitative data were analysed using the Wilcoxon signed rank test, and all P levels lower than .05 were considered significant. Qualitative data were analyzed using content analysis. There were significant increases in midwives' confidence in all four aspects of interprofessional interaction measured 6 weeks following the course. However, the doctors only reported a significant increase in one aspect, the confidence that their clinical decisions were respected by the midwives with whom they worked. The qualitative data demonstrated an appreciation of different professional approaches to clinical situations and the importance of teamwork, communication, respect, and understanding. While most participants were positive about the advantages of IPE, just under half also believed there were some disadvantages, particularly due to the variable learning needs of individual professionals. Both doctors and midwives reported various benefits from IPE, and many believed that IPE assisted maternity team collaboration and communication in the workplace. However, educators need to skillfully manage IPE sessions to ensure a similar distribution of learning and that opportunities for discussion are equivalent for all individuals and professional groups.

seminars, tutorial discussion groups (n=21, 84%), case presentations (n=11, 44%) and community projects (n=11, 44%) augmented by preliminary orientation and ongoing interaction with clinicians during placement. The studies reviewed demonstrate that rural clinical learning environments provide rich and varied IPE opportunities for students that increase their interprofessional understanding, professional respect for other roles, and awareness of the collaborative and interprofessional nature of rural practice. This review addresses the lack of attention given to understanding IPE in the rural context, provides Australian and international evidence that initiatives are being offered to diverse student groups undertaking placements in rural settings and proposes a research agenda to develop a relevant framework to support rural IPE. Rural clinical learning environments afford a rich resource whereby health professionals can conceptualise IPE creatively and holistically to construct transformative learning experiences for students. This review develops a case for supporting the development, trialling, evaluation and translation of IPE initiatives that harness the opportunities afforded by rural placements. Further research is required to examine the ways to optimise IPE opportunities in the rural clinical context, including the potential for simulation-based activities, the challenges to achieving sustainable programs, and to evaluate the impact of interprofessional education on collaboration and health outcomes.

To ensure high quality patient care an effective interprofessional collaboration between healthcare professionals is required. Interprofessional education (IPE) has a positive impact on team work in daily health care practice. Nevertheless, there are various challenges for sustainable implementation of IPE. To identify enablers and barriers of IPE for medical and nursing students as well as to specify impacts of IPE for both professions, the 'Cooperative academical regional evidence-based Nursing Study in Mecklenburg-Western Pomerania' (Care-N Study M-V) was conducted. The aim is to explore, how IPE has to be designed and implemented in medical and nursing training programs to optimize students' impact for IPC. A qualitative study was conducted using the Delphi method and included 25 experts. Experts were selected by following inclusion criteria: (a) ability to answer every research question, one question particularly competent, (b) interdisciplinarity, (c) sustainability and (d) status. They were purposely sampled. Recruitment was based on existing collaborations and a web based search. The experts find more enablers than barriers for IPE between medical and nursing students. Four primary arguments for IPE were mentioned: (1) development and promotion of interprofessional thinking and acting, (2) acquirement of shared knowledge, (3) promotion of beneficial information and knowledge exchange, and (4) promotion of mutual understanding. Major barriers of IPE are the coordination and harmonization of the curricula of the two professions. With respect to the effects of IPE for IPC, experts mentioned possible improvements on (a) patient level and (b) professional level. Experts expect an improved patient-centered care based on better mutual understanding and coordinated cooperation in interprofessional health care teams. To sustainably implement IPE for medical and nursing students, IPE needs endorsement by both, medical and nursing faculties. In conclusion, IPE

Hepatoprotective Effects of Ixora parviflora Extract against Exhaustive Exercise-Induced Oxidative Stress in Mice

Full Text Available Ixora parviflora, a species of the Rubiaceae, is rich in polyphenols and flavonoids, and has been traditionally used as a folk medicine. An I. parviflora extract (IPE has great antioxidant activity in vitro, including a scavenging effect on superoxide radicals, reducing power, and ferrous ion-chelating ability. However, whether IPE is efficacious against oxidative damage in vivo is not known. The purpose of this study was to determine the protective effects of IPE treatment on hepatic oxidative stress and antioxidant defenses after exhaustive exercise in mice. Fifty male C57BL/6 mice (6 week old were randomly divided into five groups and designated a sedentary control with vehicle (C, and exhaustive exercise with vehicle (IPE0, low dosage (IPE10, medium dosage (IPE50 and high dosage (IPE100 of IPE at 0, 10, 50, and 100 mg/kg, respectively. After a single bout of exhaustive swimming exercise challenge, levels of blood ammonia and creatine kinase (CK, and hepatic superoxide dismutase (SOD protein expression, thiobarbituric acid-reactive substance (TBARS, and gp91phox, p22phox, and p47phox subunits of nicotinamide adenine dinucleotide phosphate (NADPH oxidase expressions in the IPE0 group were significantly affected compared to those of the C group, but they were all significantly inhibited by the IPE treatments. Results of the present in vivo study in mice indicate that I. parviflora extract possesses antioxidative and hepatoprotective potential following exhaustive exercise.

Short-chain fatty acids (SCFA) produced through fermentation of nondigestible carbohydrates by the gut microbiota are associated with positive metabolic effects. However, well-controlled trials are limited in humans. To develop a methodology to deliver SCFA directly to the colon, and to optimise colonic propionate delivery in humans, to determine its role in appetite regulation and food intake. Inulin SCFA esters were developed and tested as site-specific delivery vehicles for SCFA to the proximal colon. Inulin propionate esters containing 0-61 wt% (IPE-0-IPE-61) propionate were assessed in vitro using batch faecal fermentations. In a randomised, controlled, crossover study, with inulin as control, ad libitum food intake (kcal) was compared after 7 days on IPE-27 or IPE-54 (10 g/day all treatments). Propionate release was determined using (13) C-labelled IPE variants. In vitro, IPE-27-IPE-54 wt% propionate resulted in a sevenfold increase in propionate production compared with inulin (P inulin (439.5 vs. 703.9 kcal, P = 0.025) and IPE-54 (439.5 vs. 659.3 kcal, P = 0.025), whereas IPE-54 was not significantly different from inulin control. IPE-27 significantly reduced food intake suggesting colonic propionate plays a role in appetite regulation. Inulin short-chain fatty acid esters provide a novel tool for probing the diet-gut microbiome-host metabolism axis in humans. © 2016 The Authors.

Faulted systems recovery experience. Final report, May 1992

International Nuclear Information System (INIS)

1992-05-01

This report addresses the recovery (i.e., return to service from a faulted, or otherwise unavailable, condition) of important nuclear power plant front-line and support systems and equipment. It contains information based on operating experience relative to the times to recover from a variety of plant events. It also indicates the nature of the operator actions involved. This information is intended to provide useful insights to utilities who are undertaking Individual Plant Examinations (IPEs) per Generic Letter 88-20 of the Nuclear Regulatory Commission. The report provides a database of recovery experience primarily derived from Licensee Event Reports (LERs). The database contains recovery duration information for 205 demand events and 98 nondemand events. In particular, it contains recovery durations for 42 pump related and 143 valve related events that are representative of demand conditions. Experience shows that, overall, about one-half of all pumps and valves are recovered in 30 minutes or less. Specific recovery experience is dependent on the equipment type, the plant system involved, and the failure mode encountered. (author)

During the current research period, we have set forth the methodology for identification of a severe accident, developed a framework for hydrogen management decision trees, and analyzed the literature on hydrogen management and experimental data for hydrogen bum. Specifically, we have summarized me results for information needs in a severe accident obtained in the U.S. and other countries, and applied the methodology to the reference plant YGN 3 and 4 as part of severe accident management. We have also examined the existing instruments in terms of their availability and survivability during a severe accident, and identified additionally needed information needs and instruments. We have identified dominant accident sequences for me reference plant YGN 3 and 4 to construct decision trees, and extracted available data from the IPE study of the plant. Based upon the data we have performed preliminary study on the decision tree and decision node. Last, we have examined various mechanisms for hydrogen generation and reIevant experimental data to predict me amount of hydrogen generation and governing factors in me process. We have also reviewed the hydrogen generation related models in the severe accident analysis.

The purpose of this retrospective qualitative case report is to describe how a case-based, virtual patient interprofessional education (IPE) simulation activity was utilized to achieve physician assistant (PA), physical therapy (PT) and occupational therapy (OT) student IPE learning outcomes. Following completion of a virtual patient case, 30 PA, 46 PT and 24 OT students were required to develop a comprehensive, written treatment plan and respond to reflective questions. A qualitative analysis of the submitted written assignment was used to determine whether IPE learning objectives were met. Student responses revealed three themes that supported the learning objectives of the IPE experience: benefits of collaborative care, role clarification and relevance of the IPE experience for future practice. A case-based, IPE simulation activity for physician assistant and rehabilitation students using a computerized virtual patient software program effectively facilitated achievement of the IPE learning objectives, including development of greater student awareness of other professions and ways in which collaborative patient care can be provided.

Full Text Available Introduction: Transplantation of an intact differentiated retinal pigment epithelial (RPE cell layer may provide a means to treat Age-Related Macular Degeneration (AMD. However, harvesting RPE cells can be a technically complicated procedure. Our current work aimed to prepare intact differentiated iris pigment epithelial (IPE cell layers, which are easy to obtain and have the same embryonic origin and similar properties as RPE cells, on ePTFE substrates for transplantation purposes to rescue deteriorated photoreceptors in AMD. Methods: IPE cells isolated from rat eyes were seeded on different substrates, including fibronectin n-heptylamine (HA ePTFE substrates, HA ePTFE substrates, ePTFE substrates and fibronectin tissue culture polystyrene (TCPS as control. Cell number and morphology were assessed at each time interval. The formation of tight junction was examined by immunostaining of junction proteins. Results: An obvious increasing trend of cell number was observed in IPE cells on fibronectin n-heptylamine (HA ePTFE substrate, exhibiting heavy pigmentation and epithelial morphology. At Day 28, tight junction formation was indicated by cell-cell junctional proteins along cell borders. Conclusion: Harvested IPE cells cultured on fibronectin HA-ePTFE substrates can differentiate and form a cell monolayer that may be suitable for transplantation.

The World Health Organization describes interprofessional education (IPE) and collaboration as necessary components of all health professionals' education - in curriculum and in practice. However, no standard framework exists to guide healthcare settings in developing or selecting an IPE model that meets the learning needs of licensed practitioners in practice and that suits the unique needs of their setting. Initially, a broad review of the grey literature (organizational websites, government documents and published books) and healthcare databases was undertaken for existing IPE models. Subsequently, database searches of published papers using Scopus, Scholars Portal and Medline was undertaken. Through this search process five IPE models were identified in the literature. This paper attempts to: briefly outline the five different models of IPE that are presently offered in the literature; and illustrate how a healthcare setting can select the IPE model within their context using Reeves' seven key trends in developing IPE. In presenting these results, the paper contributes to the interprofessional literature by offering an overview of possible IPE models that can be used to inform the implementation or modification of interprofessional practices in a tertiary healthcare setting.

Integrating interprofessional education (IPE) activities and curricular components in health professions education has been emphasized recently by the inclusion of accreditation standards across disciplines. The Interprofessional Education Collaborative (IPEC) established IPE competencies in 2009, but evaluating how activities link to competencies has not been investigated in depth. The purpose of this project is to investigate how well two IPE activities align with IPEC competencies. To evaluate how our IPE activities met IPEC competencies, we developed a checklist and an observation instrument. A brief description of each is included as well as the outcomes. We analyzed Disaster Day, a simulation exercise that includes participants from Nursing, Medicine, and Pharmacy, and Interprofessional Healthcare Ethics (IPHCE), a course that introduced medical, nursing, and pharmacy students to ethical issues using didactic sessions and case discussions. While both activities appeared to facilitate the development of IPE competencies, Disaster Day aligned more with IPEC competencies than the IPHCE course and appears to be a more comprehensive way of addressing IPEC competencies. However, offering one IPE activity or curricular element is not sufficient. Having several IPE options available, utilizing the tools we developed to map the IPE curriculum and evaluating competency coverage is recommended.

The effective incorporation of interprofessional education (IPE) within health professional curricula requires the synchronised and systematic collaboration between and within the various stakeholders. Higher education institutions, as primary health education providers, have the capacity to advocate and facilitate this collaboration. However, due to the diversity of stakeholders, facilitating the pedagogical change can be challenging and complex, and brings a degree of uncertainty and resistance. This review, through an analysis of the barriers and enablers investigates the involvement of stakeholders in higher education IPE through three primary stakeholder levels: Government and Professional, Institutional and Individual. A review of eight primary databases using 21 search terms resulted in 40 papers for review. While the barriers to IPE are widely reported within the higher education IPE literature, little is documented about the enablers of IPE. Similarly, the specific identification and importance of enablers for IPE sustainability and the dual nature of some barriers and enablers have not been previously reported. An analysis of the barriers and enablers of IPE across the different stakeholder levels reveals five key "fundamental elements" critical to achieving sustainable IPE in higher education curricula.

The benefits of interprofessional education 10 years on.

Illingworth, Paul; Chelvanayagam, Sonya

2017-07-27

Interprofessional education (IPE) was first conceived in 1973 by a World Health Organization (WHO) expert group in Geneva. WHO member states were then charged with implementing medical education IPE pilot projects and from then to today there has a been a rapid proliferation in the number of publications on the subject. IPE has generated research into its use, conferences specific to IPE, organisations dedicated to it and policy championing it. The authors question whether there has been any major shift in the silos in which different professions might be working. The authors published an article on the benefits of IPE ( Illingworth and Chelvanayagam, 2007 ). Ten years have now passed and many changes have been implemented and experienced in health and social care and therefore a review of the literature is required. Also, it is 7 years since the publication of WHO's report outlining the role of IPE in the preparation of health professionals ( WHO, 2010 ) and, increasingly, UK Government policy champions collaborative and integrated working. The conclusions from the 2007 article acknowledged the development of IPE; however, it highlighted the need for empirical evidence to demonstrate the effectiveness of IPE in service user and carer outcomes. This article will explore whether IPE has achieved the benefits discussed in the previous article and what developments have occurred since it was published.

This study aimed to identify the effects of interprofessional resuscitation skills teaching on medical and nursing students' attitudes, leadership, team-working and performance skills. Year 2 medical and nursing students learned resuscitation skills in uniprofessional or interprofessional settings, prior to undergoing observational ratings of video-recorded leadership, teamwork and skills performance and subsequent focus group interviews. The Readiness for Interprofessional Learning Scale (RIPLS) was administered pre- and post-intervention and again 3-4 months later. There was no significant difference between interprofessional and uniprofessional teams for leadership, team dynamics or resuscitation tasks performance. Gender, previous interprofessional learning experience, professional background and previous leadership experience had no significant effect. Interview analysis showed broad support for interprofessional education (IPE) matched to clinical reality with perceived benefits for teamwork, communication and improved understanding of roles and perspectives. Concerns included inappropriate role adoption, hierarchy issues, professional identity and the timing of IPE episodes. The RIPLS subscales for professional identity and team-working increased significantly post-intervention for interprofessional groups but returned to pre-test levels by 3-4 months. However, interviews showed interprofessional groups retained a 'residual positivity' towards IPE, more so than uniprofessional groups. An intervention based on common, relevant, shared learning outcomes set in a realistic educational context can work with students who have differing levels of previous IPE and skills training experience. Qualitatively, positive attitudes outlast quantitative changes measured using the RIPLS. Further quantitative and qualitative work is required to examine other domains of learning, the timing of interventions and impact on attitudes towards IPE.

Consumerism of image and performance enhancement drugs (IPEDs) is a world-wide public health concern. Given anecdotal reporting of increased normalisation of IPED use and uptake of British South Asian male IPED users at UK needle and syringe exchange services, the study aimed to explore use of IPEDs among this under-researched ethnic group. 20 in depth interviews were conducted with a purposive sample of British South Asian males attending harm reduction outreach in the North East of England. The interviews explored motives for use of IPEDs, sourcing routes, information seeking, injecting behaviours and cultural and community sensitivities around IPED use among this group. The data was collected and analysed using the Interpretative Phenomenological Analysis approach (IPA). Motives for use centred on the achievement of enhanced definition and density of muscle, and improved recovery from training and injuries. All participants reported initial stimulation of interest and triggers to seek information on IPEDs due to social media, community and peer messages. Diverse forms of IPED use were described, with rational and moderated use common among older participants. In contrast younger participants adopted more excessive use in seeking short cuts to attaining muscle size. Sourcing of androgenic-anabolic steroids (AAS) and growth hormones from originating countries (Pakistan, India) was reported, along with diversification of entrepreneurial activity into IPED dealing networks. Sellers were generally reported to provide effective and reliable products and mentoring to inexperienced users. Group injecting practices were common. IPED use was observed by some as health promotion medium within religious contexts. Crime deterrence and drug abstinence occurred for some while involved in AAS cycles. The study is intended to contribute to health policy and practice debate around the targeting of dedicated education, outreach and harm reduction for ethnic groups engaged in IPED

In the anoxic soil of wetlands, microbes produce methane (CH4), a greenhouse gas. Prior studies have documented an increase in CH4 emissions as plant productivity increases, likely due to plants releasing more labile organic carbon from roots. But in the field, it is difficult to separate changes in plant productivity and root carbon exudation from other seasonal changes that can affect methane emissions, e.g. temperature. Clarifying the role that root exudation plays in fueling methane production is important because increasing atmospheric temperatures and CO2 levels are projected to increase plant productivity and exudation. To advance understanding of climate-methane feedbacks, this study tracked the flow of carbon from plants into the wetland rhizosphere as plant productivity increased in controlled laboratory conditions. We grew Carex aquatilis, a wetland sedge, in peat-filled rootboxes. Both early and late during the plant growth cycle, we exposed plants to headspace 13CO2, which the plants fixed. Some of this labeled carbon was exuded by the roots and used by rhizosphere microbes. We tracked the isotope ratio of emitted CH4 to establish the time required for plant-released carbon to fuel methanogenesis, and to determine the relative contribution of plant-derived carbon to total CH4 emission. We destructively harvested root and rhizosphere samples from various locations that we characterized by isotope ratio mass spectrometry (MS) to determine isotopic enrichment and therefore relative abundance of root exudates. We analyzed additional aliquots of rhizosphere soil by Fourier transform ion cyclotron resonance MS to track chemical changes in soil carbon as root exudates were converted into methane. To advance mechanistic understanding of the synergistic and competitive microbial interactions that affect methane dynamics in the wetland rhizosphere, we used fluorescence in-situ hybridization to visualize microbial community composition and spatial associations

The scope of Level 2+ PSA includes the assessment of dose risk which is associated with the exposures of the radioactive nuclides escaping from nuclear power plants during severe accidents. The establishment of data base for the exposure dose in Korea nuclear power plants may contribute to preparing the accident management programs and periodic safety reviews. In this study the ORIGEN, MELCOR and MACCS code were employed to produce a integrated framework to assess the radiation source term risk. The framework was applied to a reference plant. Using IPE results, the dose rate for the reference plant was calculated quantitatively

Full Text Available CrossFit™, a popular high-intensity training modality, has been the subject of scrutiny, with concerns of elevated risk of injury and health. Despite these concerns empirical evidence regarding physiologic stresses including acute oxidative stress is lacking. Therefore, the purpose of this investigation was to examine the acute redox response to a CrossFit™ bout. Furthermore, these findings were compared to a high-intensity treadmill bout as a point of reference. Ten males 26.4 ± 2.7 yrs having three or more months of CrossFit™ experience participated in the present study. Blood plasma was collected at four time points: Pre-exercise (PRE, immediately-post-exercise (IPE, 1 hr-post (1-HP and 2 hr-post (2-HP, to examine oxidative damage and antioxidant capacity. Regarding plasma oxidative damage, CrossFit™ and Treadmill elicited a time-dependent increase of lipid peroxides 1-HP (CrossFit™=+143%,Treadmill=+115% and 2-HP (CrossFit™=+256%,Treadmill+167%. Protein Carbonyls were increased IPE in CF only (+5%, while a time-dependent decrease occurred 1-HP (CrossFit™=−16%,Treadmill=−8% and 2-HP (CF=−16%,TM=−1% compared to IPE.

No trial-dependent differences were observed in any biomarker of oxidative stress. The CrossFit™ bout elicited an acute blood oxidative stress response comparable to a traditional bout of high-intensity treadmill running. Results also confirm that exercise intensity and the time course of exercise recovery influence oxidative responses.

Interprofessional collaborative care (IPC) is defined as working within and across healthcare disciplines and is considered essential to achieve a more inclusive, patient-centred care, provide a means to support patient safety and address global healthcare provider shortages. Interprofessional education (IPE) provides the knowledge and experience students need to achieve these goals. ADEE/ADEA held a joint international meeting 8-9 May 2017, with IPE being one of four topic areas discussed. The highly interactive workshop format, where "everyone was an expert," supported discussion, sharing and creative problem-solving of over seventy-one participants from twenty-nine countries. IPE participants broke out into five groups over a two-day period discussing three main areas: challenges and barriers to implementing IPE within their institution or country; discussion of successful models of introducing and assessing IPE initiatives, and exploring best practices and next steps for implementation for each group member. A mind-mapping model was used to graphically display participants' thoughts and suggestions. Key themes, revealed through the visual mind maps and discussion, included the following: IPE should lead to and enhance patient-centred care; student involvement is key to IPE success; faculty development and incentives can facilitate adoption and implementation of IPE; the role of a "champion" and leadership structure and commitment is important to move IPE forward; and IPE must be tailored to the unique issues found in each country. Overall, there was a high level of interest to continue both collaboration and discussion to learn from others beyond the London meeting. © 2018 John Wiley & Sons A/S.

DNA was extracted from different morphological types of hypohaploid Nicotiana plumbaginifolia plants. The cellular levels of chloroplast DNA (expressed as percent of total DNA) were found to be approximately two- to threefold higher in two albino hypohaploids than in a green hypohaploid. The level of chloroplast DNA in the green hypohaploid was not significantly different from either in vitro or in vivo grown haploid N. plumbaginifolia plants. Molecular hybridization with DNA probes for the large subunit of ribulose bisphosphate carboxylase from spinach and with Pvull fragments representing the entire Nicotiana tabacum chloroplast genome revealed no gross qualitative differences in the chloroplast DNAs of hypohaploid plants. Based on these observations we have concluded that the lack of chloroplast function observed in the albino forms of hypohaploid N. plumbaginifolia plants is not due to changes in the chloroplast genome.

Botanical pharmacopoeias are non-random subsets of floras, with some taxonomic groups over- or under-represented. Moerman [Moerman, D.E., 1979. Symbols and selectivity: a statistical analysis of Native American medical ethnobotany, Journal of Ethnopharmacology 1, 111-119] introduced linear regression/residual analysis to examine these patterns. However, regression, the commonly-employed analysis, suffers from several statistical flaws. We use contingency table and binomial analyses to examine patterns of Shuar medicinal plant use (from Amazonian Ecuador). We first analyzed the Shuar data using Moerman's approach, modified to better meet requirements of linear regression analysis. Second, we assessed the exact randomization contingency table test for goodness of fit. Third, we developed a binomial model to test for non-random selection of plants in individual families. Modified regression models (which accommodated assumptions of linear regression) reduced R(2) to from 0.59 to 0.38, but did not eliminate all problems associated with regression analyses. Contingency table analyses revealed that the entire flora departs from the null model of equal proportions of medicinal plants in all families. In the binomial analysis, only 10 angiosperm families (of 115) differed significantly from the null model. These 10 families are largely responsible for patterns seen at higher taxonomic levels. Contingency table and binomial analyses offer an easy and statistically valid alternative to the regression approach.

Fukushima Daiichi Nuclear Power Plant was utterly destroyed by The Great East Japan Earthquake which happened on March 11, 2011, and followed by radioactive contamination to the surrounding areas. Based on the known radioactive iodine ("1"3"1I) which led to thyroid cancer in children after the Chernobyl nuclear power plant disaster in 1986, children living in Fukushima should be carefully observed for the development of thyroid cancer. Fukushima Prefecture and Fukushima Medical University started ''Fukushima Health Management Survey'' in May 2011, which includes screening for thyroid cancer by ultrasonography (Thyroid Ultrasound Examination). Thyroid Ultrasound Examination would cover roughly 360,000 residents aged 0 to 18 years of age at the time of the nuclear disaster. The initial screening is to be performed within the first three years after the accident, followed by complete thyroid examinations from 2014 onwards, and the residents will be monitored regularly thereafter. As Thyroid Ultrasound Examination is being mainly performed by medical staff at Fukushima Medical University, there is insufficient manpower to handle the large number of potential examinees. Thus, specialists of thyroid diseases from all over Japan have begun to support this examination. Six endocrinologists including the authors belonging to the National Defense Medical College are cooperating in part of this examination. This paper briefly reports the outline of Thyroid Ultrasound Examination and our cooperation. (author)

Cogeneration, the process of using reject heat from electric energy generation plants, offers substantial savings in energy consumption and thus is likely to see increased implementation, especially in the form of district heating, over the next few decades. The use of fusion plants for cogeneration offers added advantages of potentially low marginal costs and reduced siting restrictions compared to nuclear and coal plants, and freedom from use of limited fossil fuels. Fusion can thus provide increased economic incentive to the implementation of cogeneration systems. Conversely, cogeneration improves the economics of fusion and thus provides both added incentive for its development and reduced economic requirements on commercial fusion technologies

Full Text Available Objectives: Interprofessional collaboration is becoming increasingly important in health care for various reasons. Interprofessional Education (IPE can provide a basis for this.The aim of our study was to find out how medical (MS and nursing students (NS think about their own and other professions, what they know about each other, how strong their willingness to embrace IPE is, and what forms of IPE they deem useful.Methodology: Seven IPE experts rated the two measuring instruments, Readiness for Interprofessional Learning Scale RIPLS, and Interdisciplinary Education Perception Scale IEPS in terms of relevance of the items, and the quality of translation into German. Nine RIPLS items and 13 IEPS items were considered content-valid. All MS of the University of Bern and NS of the two Bernese educational institutions for nursing were invited to the online survey in the fall of 2014 by email. Results: 498 (254 MS, 244 NS of the 2374 invited students completely filled in the questionnaire (21%.The results of the reduced RIPLS allowed no conclusive statements. When assessing their own occupational group in the IEPS, the MS attributed "competence and autonomy" to themselves significantly more frequently, while to the NS, the same was true for the item, "actual cooperation". MS know significantly less about the training of other health professionals. NS show a significantly higher willingness to embrace IPE. Teaching ethics, communication, team training, and clinical skills are deemed suitable for IPE by both groups. From the comments it appears that in both groups a majority welcomes IPE; however, the various arguments had different prevalence in both groups. Both groups fear that IPE leads to heightened stress during the study. A subgroup of MS fears a lowering of academic level. Conclusion: The results of this survey of Bernese MS and NS concerning IPE provide important information for the planning and implementation of IPE. Important steps in the

Preliminary studies of inter-professional education (IPE) among student speech-language therapists (SLTs) and student teachers suggest that workshop-based applications are beneficial in preparing participants for elements of collaborative practice. Situating IPE within the students' professional practice placements may provide another useful avenue to develop attitudes, knowledge and skills for inter-professional collaboration. Research examining the impact of different approaches to IPE is required to advance our understanding of effective design and evaluation of such initiatives. To understand how student SLTs and student teachers develop competency for collaborative practice when co-working during professional practice placements to support children's speech and literacy development. A case study design was used to monitor the impact of the IPE. Student SLTs (n = 4) were paired with student teachers (n = 4) to participate in shared professional practice placements in junior school classrooms. An inductive thematic analysis of interviews conducted with participants after the IPE was employed to explore the development of competencies in collaborative practice. Change in inter-disciplinary knowledge and perceptions over the IPE was evaluated via survey to further explore the development of collaborative competencies. Integration of qualitative and quantitative findings suggested that participants began to develop four broad areas of collaborative competency: understanding of professional roles and expertise, communication skills to support shared decision-making, inter-dependency in supporting children's learning, and flexibility to implement alternative instructional practices. Interview analysis also revealed factors related to the facilitators and learning contexts that supported and/or limited the collaboration between participants. Shared placement experiences between student SLTs and student teachers may be an effective method for building participants

Interprofessional education (IPE) is becoming essential for students and healthcare professionals. An evolving approach to implement it is via distance education. Distance education can provide a viable solution to deliver IPE in a variety of settings. A literature search on PubMed and Academic Search Complete databases was conducted, revealing 478 articles ranging from the years of 1971-2015. The articles were screened for relevance using the following inclusion criteria: 1) Is this study implementing IPE? 2) Is this study utilizing the instructional delivery method of distance education? 3) Does this study contain students from two or more healthcare professions? Fifteen studies met the inclusion criteria and were systematically analyzed to identify data relevant for this review. Findings from this review provide a description of the teaching methods involved in distance education in promoting IPE and an assessment of the continuing use of distance education to foster IPE. Success varied depending upon on the distance-based instructional model utilized to facilitate IPE. Incorporating distance education to implement IPE can be an opportunity to develop team collaboration and communication skills among students. Teaching models presented in this review have the potential to be adapted to methods that leverage the power of evolving technology. Further research is needed to understand which distance education instructional delivery models best maximize the IPE experience. Copyright © 2017 Elsevier Inc. All rights reserved.

The importance and necessity of interprofessional collaboration (IPC) present challenges for educators as they determine how best to achieve IPC through interprofessional education (IPE). Simulation-based teaching has been shown to enhance students' understanding of professional roles and promote positive attitudes toward team members; yet, empirical evidence providing direction on the conditions necessary to promote these positive outcomes is lacking. This study used a quasi-experimental design with a pre-/post-test to examine changes in undergraduate healthcare students' perceptions and attitudes toward IPC following their participation in an interprofessional simulation program. Allport's (1954) intergroup contact theory was used to help understand the nature of this IPE workshop and its reported outcomes. Participants included students in the final year of their respective programs (n = 84) such as pharmacy technician, paramedic, nursing and occupational therapy assistant/physical therapy assistant programs. These students were engaged in simulation exercises with interactive contact opportunities. Using the interdisciplinary education perceptions scale, statistically significant increases in positive attitudes in three of four sub-scales were found. An analysis of the structure and format of the workshop suggests that this IPE initiative fulfilled the key conditions suggested by intergroup contact theory. Attention to the key conditions provided by Allport's theory in the context of successful intergroup relationships may help provide direction for educators interested in planning IPE initiatives with student groups enrolled in various health programs.

The US Nuclear Regulatory Commission (NRC) and the industry are both participating in the identification of measures that can prevent the progression of a severe accident or mitigate its consequences. Information important for evaluating these accident management strategies for specific plants is expected to result from the ongoing Individual Plant Evaluation (IPE) program. However, NRC staff have identified a number of generic strategies which may not have to await the results of the IPE program and therefore can be considered for earlier implementation. The NRC requested two of its contractors, Brookhaven National Laboratory (BNL) and Battelle Pacific Northwest Laboratories (PNL) to evaluate these strategies. The twenty one candidate strategies fall under three broad global strategies: (1) conserving and replenishing limited resources, (2) use of systems/components in innovative applications, and (3) defeating interlocks and component protective trips in emergencies. Some strategies apply to BWRs or PWRs only, other apply to both types of plants. This paper describes the evaluation of the strategies performed by Brookhaven National Laboratory. Brookhaven National Laboratory assessed the proposed strategies by first detailing the objective of the strategy and listing the actions involved in the implementation. A description of the plant systems associated with the strategy was given. Next, the applicability of existing rules or plant procedures to a particular strategy was investigated. This was accomplished by a fairly detailed, but by no means exhaustive review of the emergency operating procedures of several plants, as well as utility and NRC reports related to accident management

Teamwork and collaboration have been recognized as essential competencies for health care providers in the field of maternity care. Health care policy and regulatory bodies have stressed the importance of Interprofessional Education (IPE) for learners in this field; however, there is little evidence of sustained application of pre-qualifying IPE to the realm of interprofessional collaboration (IPC) in practice following qualification. The aim of this research was to understand how newly qualified midwives applied their IPE training to professional practice. A purposive sample of midwifery students, educators, new midwives and Heads of Midwifery from four universities in the United Kingdom participated in semi-structured interviews, questionnaires and focus groups. Qualitative, grounded theory methodology was used to develop the emerging theory. Newly qualified midwives appeared better able to integrate their IPE training into practice when IPE occurred in a favourable learning environment that facilitated acquisition and application of IPE skills and that recognized the importance of shared partnership between the university and the clinical workplace.

2016-06-01

Full Text Available Background: Interprofessional education (IPE is an important component to training health care professionals. Research is limited in exploring the attitudes that faculty hold regarding IPE and what barriers they perceive to participating in IPE. The purpose of this study was to identify faculty attitudes about IPE and to identify barriers to participating in campus-wide IPE activities. Methods: A locally used questionnaire called the Nebraska Interprofessional Education Attitudes Scale (NIPEAS was used to assess attitudes related to interprofessional collaboration. Questions regarding perceived barriers were included at the end of the questionnaire. Descriptive and non-parametric statistics were used to analyze the results in aggregate as well as by college. In addition, open-ended questions were analyzed using an immersion/crystallization framework to identify themes. Results: The results showed that faculty had positive attitudes of IPE, indicating that is not a barrier to participating in IPE activities. Most common barriers to participation were scheduling conflicts (x24,285=19.17, p=0.001, lack of department support (4,285=10.09, p=0.039, and lack of awareness of events (x24,285=26.38, p=0.000. Narrative comments corroborated that scheduling conflicts are an issue because of other priorities. Those who commented also added to the list of barriers, including relevance of the activities, location, and prior negative experiences. Discussion: With faculty attitudes being positive, the exploration of faculty's perceived barriers to IPE was considered even more important. Identifying these barriers will allow us to modify our IPE activities from large, campus-wide events to smaller activities that are longitudinal in nature, embedded within current curriculum and involving more authentic experiences.

Online learning (e-learning) has a nascent but established history. Its application to interprofessional education (IPE), however, is relatively new. Over the past 2 decades the Internet has been used increasingly to mediate education. We have come past the point of "should we use the Internet for education" to "how should we use the Internet for education." Research has begun on the optimal development of online learning environments to support IPE. Developing online IPE should follow best practices in e-learning generally, though there are some special considerations for acknowledging the interprofessional context and clinical environments that online IPE is designed to support. The design, development, and deployment of effective online IPE must therefore pay special attention to the particular constraints of the health care worker educational matrix, both pre- and postlicensure. In this article we outline the design of online, interprofessional health sciences education. Our work has involved 4 educational and 4 clinical service institutions. We establish the context in which we situate our development activities that created learning modules designed to support IPE and its transfer into new interprofessional health care practices. We illustrate some best practices for the design of effective online IPE, and show how this design can create effective learning for IPE. Challenges exist regarding the full implementation of interprofessional clinical practice that are beginning to be met by coordinated efforts of multiple health care education silos.

Regulatory analysis for the resolution of Generic Safety Issue 105: Interfacing system loss-of-coolant accident in light-water reactors

International Nuclear Information System (INIS)

1993-07-01

An interfacing systems loss of coolant accident (ISLOCA) involves failure or improper operation of pressure isolation valves (PIVs) that compose the boundary between the reactor coolant system and low-pressure rated systems. Some ISLOCAs can bypass containment and result in direct release of fission products to the environment. A cost/benefit evaluation, using three PWR analyses, calculated the benefit of two potential modifications to the plants. Alternative 1 is improved plant operations to optimize the operator's performance and reduce human error probabilities. Alternative 2 adds pressure sensing devices, cabling, and instrumentation between two PIVs to provide operators with continuous monitoring of the first PIV. These two alternatives were evaluated for the base case plants (Case 1) and for each plant, assuming the plants had a particular auxiliary building design in which severe flooding would be a problem if an ISLOCA occurred. The auxiliary building design (Case 2) was selected from a survey that revealed a number of designs with features that provided less than optimal resistance to ECCS equipment loss caused by a ISLOCA-induced environment. The results were judged not to provide sufficient basis for generic requirements. It was concluded that the most viable course of action to resolve Generic Issue 105 is licensee participation in individual plant examinations (IPEs)

A framework for assessing hydrogen management strategies involving multiple decisions

An accident management framework consisting of multiple and sequential decisions is developed and applied to a hydrogen control strategy for a reference plant. The compact influence diagrams including multiple decisions are constructed and evaluated with MAAP4 calculations. Each decision variable, represented by a node in the influence diagrams, has an uncertainty distribution. Using the values from the IPE (Individual Plant Examinations) report for the reference plant (UCN 3 and 4), the hydrogen control and accident management strategies are assessed. In this paper, a problem with two decisions is modeled for a simple illustration of the process involved. One decision is whether or not to actuate igniters at the time of core uncovery. Another decision is whether or not to turn on the containment sprays. We chose a small-break loss-of-coolant accident (LOCA) sequence, which was one of the dominant accident sequences in the reference plant. The framework involves the modeling of the decision problem by using decision-making tools, data analysis, and the MAAP4 calculations. It is shown that the proposed framework with a new measure for assessing hydrogen control is flexible enough to be applied to various accident management strategies. (author)

Interprofessional education (IPE) in health and human services educational and clinical settings has proliferated internationally. The use of information and communication technologies (ICTs) in the facilitation of interprofessional learning is also growing, yet reviews of the effectiveness of ICTs in the delivery of pre- and/or post-licensure IPE have been limited. The current study's purpose was to review the evaluation outcomes of IPE initiatives delivered using ICTs. Relevant electronic databases and journals from 1996 to 2013 were searched. Studies which evaluated the effectiveness of an IPE intervention using ICTs were included and analyzed using the Barr et al. modified Kirkpatrick educational outcomes typology. Fifty-five studies were identified and a majority reported evaluation findings at the level 1 (reaction/satisfaction). Analysis revealed that learners react favorably to the use of ICTs in the delivery of IPE, and ICT-mediated IPE can lead to positive attitudinal and knowledge change. A majority of the studies reported positive evaluation outcomes at the learner satisfaction level, with the use of web-based learning modalities. The limited number of studies at other levels of the outcomes typology and deficiencies in study designs indicate the need for more rigorous evaluation of outcomes in ICT-mediated IPE.

Integrating interprofessional education in community-based learning activities: case study.

Faculty of Medicine/Suez Canal University (FOM/SCU) students are exposed to clinical practice in primary care settings within the community, in which they encounter patients and begin to work within interprofessional health teams. However, there is no planned curricular interaction with learners from other professions at the learning sites. As in other schools, FOM/SCU faces major challenges with the coordination of community-based education (CBE) program, which include the complexity of the design required for Interprofessional Education (IPE) as well as the attitudinal barriers between professions. The aim of the present review is to: (i) describe how far CBE activities match the requirements of IPE, (ii) explore opinions of graduates about the effectiveness of IPE activities, and (iii) present recommendations for improvement. Graduates find the overall outcome of their IPE satisfactory and believe that it produces physicians who are familiar with the roles of other professions and can work in synergy for the sake of better patient care. However, either a specific IPE complete module needs to be developed or more IPE specific objectives need to be added to current modules. Moreover, coordination with stakeholders from other health profession education institutes needs to be maximized to achieve more effective IPE.

Erectile dysfunction and premature ejaculation: interrelationships and psychosexual factors.

Both erectile dysfunction (ED) and premature ejaculation (PE) impair the quality of sexual intercourse for both men and their female partners. This study aims to examine with a large representative sample the interrelationships of measures of ED, PE, typical intravaginal ejaculatory latency time (IELT), men's perceived relationship quality with their mother, and age of first being in love. In this cross-sectional study, a nationally representative sample of 960 Czech coitally experienced men (aged 15-84), provided age, International Index of Erectile Function 5-item (IIEF-5), Index of Premature Ejaculation (IPE) scores, IELT, rating of relationship with their mother, and age at first being in love. Correlations, partial correlations adjusting for age, analysis of covariance (ANCOVA), and multiple regression statistical methods were used. IIEF-5, IPE, and IELT were significantly intercorrelated (IIEF-5 and IPE: r=0.64). Better IIEF-5 scores were associated with younger age at first (and ever) being in love. Poorer IPE score, shorter IELT, and mild-moderate ED were associated with poorer perceived mother relationship (which was also associated with first being in love at an older age). Multiple regression analyses revealed that: (i) greater IELT was associated with better erectile function and better mother relationship, but not with age; and (ii) IELT of mother relationship and poorer IIEF-5, but marginally with age. History of homosexual activity was unrelated to IIEF-5, IPE, IELT, and perceived mother relationship scores. The findings suggest that degrees of ED and PE are often comorbid, and both ED and PE are associated with less favorable early experiences with women. Brody S and Weiss P.

Louder than words: power and conflict in interprofessional education articles, 1954-2013.

Interprofessional education (IPE) aspires to enable collaborative practice. Current IPE offerings, although rapidly proliferating, lack evidence of efficacy and theoretical grounding. Our research aimed to explore the historical emergence of the field of IPE and to analyse the positioning of this academic field of inquiry. In particular, we sought to investigate the extent to which power and conflict - elements central to interprofessional care - figure in the IPE literature. We used a combination of deductive and inductive automated coding and manual coding to explore the contents of 2191 articles in the IPE literature published between 1954 and 2013. Inductive coding focused on the presence and use of the sociological (rather than statistical) version of power, which refers to hierarchies and asymmetries among the professions. Articles found to be centrally about power were then analysed using content analysis. Publications on IPE have grown exponentially in the past decade. Deductive coding of identified articles showed an emphasis on students, learning, programmes and practice. Automated inductive coding of titles and abstracts identified 129 articles potentially about power, but manual coding found that only six articles put power and conflict at the centre. Content analysis of these six articles revealed that two provided tentative explorations of power dynamics, one skirted around this issue, and three explicitly theorised and integrated power and conflict. The lack of attention to power and conflict in the IPE literature suggests that many educators do not foreground these issues. Education programmes are expected to transform individuals into effective collaborators, without heed to structural, organisational and institutional factors. In so doing, current constructions of IPE veil the problems that IPE attempts to solve. © 2015 The Authors Medical Education Published by John Wiley & Sons Ltd.

Developing asynchronous online interprofessional education.

Sanborn, Heidi

2016-09-01

For many health programmes, developing interprofessional education (IPE) has been a challenge. Evidence on the best method for design and implementation of IPE has been slow to emerge, with little research on how to best incorporate IPE in the asynchronous online learning environment. This leaves online programmes with no clear guidance when embarking upon an initiative to integrate IPE into the curriculum. One tool that can be effective at guiding the incorporation of IPE across all learning platforms is the Interprofessional Education Collaborative (IPEC) competencies. A project was designed to integrate the nationally defined IPEC competencies throughout an asynchronous, online baccalaureate nursing completion programme. A programme-wide review led to targeted revision of course and unit-level objectives, learning experiences, and assessments based on the IPEC framework. As a result of this effort, the programme curriculum now provides interprofessional learning activities across all courses. This report provides a method for using the IPEC competencies to incorporate IPE within various asynchronous learning assessments, assuring students learn about, with, and from other professions.

Part I of this report presents technical justification for the use of plant-reference simulators in the licensing and training of nuclear power plant operators and examines alternatives to the use of plant-reference simulators. The technical rationale is based on research on the use of simulators in other industries, psychological learning and testing principles, expert opinion and user opinion. Part II discusses the central considerations in using plant-reference simulators for licensing examination of nuclear power plant operators and for incorporating simulators into nuclear power plant training programs. Recommendations are presented for the administration of simulator examinations in operator licensing that reflect the goal of maximizing both reliability and validity in the examination process. A series of organizational tasks that promote the acceptance, use, and effectiveness of simulator training as part of the onsite training program is delineated

Interdisciplinary courses among students in occupational therapy, physical therapy, and speech-language pathology are important for addressing teamwork, communication, and understanding of professional roles, especially in pre-service training for early intervention and school-based practice where collaboration is essential. Although interprofessional education (IPE) as a part of higher education in the health sciences has been strongly encouraged, IPE courses are difficult to schedule and implement. This article discusses the challenges of developing and delivering two IPE courses in an online format, specifically the innovation that addresses logistics, time factors, and social presence for the IPE courses across two institutions.

Perceptions of interprofessional education and practice within a complementary and alternative medicine institution.

Kadar, Gena E; Vosko, Andrew; Sackett, Michael; Thompson, H Garrett Rush

2015-01-01

A survey of the constituents of a complementary and alternative medicine (CAM) institution was conducted to identify perceptions of interprofessional education (IPE) and practice (IPP). A 22 question survey was developed and administered to: chiropractic students, acupuncture and oriental medicine students, faculty and alumni of both professions, staff and administrators. The majority of the 321 respondents demonstrated positive perceptions of IPE and IPP, however many reported a lack of understanding of the distinct roles of select healthcare professions. The study also suggested that the campus community is not homogenous in its understanding of CAM or allopathic professions, or is it homogenous in its understanding of IPE and IPP. While the overall positive attitudes toward IPE and IPP imply a willingness to improve collaboration between these groups, the lack of understanding of profession-specific roles must be addressed to support effective implementation of IPE.

Risk-based selection of SSCs at Peach Bottom

The purpose of identifying risk significant systems, structures, and components (SSCS) that are within the scope of the maintenance rule is to bring a higher level of attention to a subset of those SSCS. These risk-significant SSCs will have specific performance criteria established for them, and failure to meet this performance criteria will result in establishing goals to ensure the necessary improvement in performance. The Peach Bottom individual plant examination (IPE) results were used to provide insights for the verification of proposed probabilistic risk assessment (PRA) methods set forth in the Industry Maintenance Guidelines for Implementation of the Maintenance Rule. The objective of reviewing the methods for selection of SSCs that are considered risk significant was to ensure the methods used are logical, reproducible, and can be consistently applied

A cross-sectional survey of interprofessional education across 13 healthcare professions in Japan

Directory of Open Access Journals (Sweden)

Michiko Goto

2018-05-01

Full Text Available Background: With the rapid aging of the population, collaboration among the various medical professions throughout the country is becoming increasingly indispensable in Japan. To promote collaboration in medical care, it is necessary to introduce the concept of collaboration to students at an early stage of their professional education. Despite this need, there are no core medical, healthcare and welfare education curricula in Japan that include interprofessional education (IPE. Therefore, the status of IPE in Japanese schools of medicine and other healthcare-related services is unclear. Methods: We sent 3,430 questionnaires to 13 schools of medicine and related healthcare providers: doctors, nurses, physical therapists, registered dieticians, dentists, dental hygienists, social workers, pharmacists, occupational therapists, clinical psychologists, medical administrators, certified care workers, and speech therapists. The items addressed implementation rate of IPE, teaching methods and grading methods. Results: Of the 3,430 surveys distributed, 572 completed surveys were returned (response rate 17%. Of the completed surveys, 493 qualified as valid, resulting in a final response rate of 14%. Only 19% (n = 93 of the analysed medical educational institutions included IPE instruction in their curricula. Conclusion: While many educational institutions were conducting IPE, there were important inter-institutional differences with respect to attitudes towards IPE, teaching methods, and evaluation methods. This study was unprecedented in scale, and provides important basic information for the future development of IPE in Japan.

Full Text Available This paper describes an investigation into the possibilities of the use of all three types of solid power plant wastes: fly ash (FA, flue gas desulphurization gypsum (FGD gypsum and bottom ash (BA as components of composites for road construction. Two mixtures were made: 1. power plant wastes - Portland cement (PC and 2. power plant wastes - sand (S - Portland cement (PC. The mass ratio of components in these mixtures was: 1. FA - FGD gypsum - BA - PC = 2 : 1.5 : 5 : 1.5 and 2. FA- FGD gypsum-BA - S - PC= 2 : 1.5 : 4 : 1 : 1.5. For both mixtures, the compressive strength, the mineralogical composition, the water absorption and the resistance to freeze-thaw treatment were determined 7 and 28 days after preparation of samples (mixing with water. The obtained results showed that both mixtures could have potential to be used for sub-base layers in road construction and the second mixture (with natural aggregate-sand has advantage over the first mixture in terms of compressive strength, mineralogical composition, and resistance to freeze-thaw treatment.

Students at Makerere University College of Health Sciences (MakCHS) are introduced to ethics and professionalism using the inter-professional education (IPE) model. Ethics and professionalism should be running themes throughout succeeding years of study during which students are expected to develop qualities and skills for future inter-professional practice (IPP). We performed a situation analysis of IPE and IPP among students and teaching health professionals at MakCHS to guide development of a relevant training curriculum of ethics and professionalism. A cross sectional study with quantitative and qualitative methods which included questionnaires, focus group discussions and key informant interviews. We interviewed 236 undergraduate students (148, 63 % male) and 32 teaching health professionals (25, 78 % male). Two hundred fifteen (91 %) students indicated they had joint learning activities with students of other professions and 166 (70 %) stated there was benefit in having an IPE model training curriculum. Most students (140, 59 %) strongly agreed that learning with other students will make them more effective members of the health team. Whereas the respondents reported inter professionalism as being well articulated in their course curricula, more than half said IPE is only implemented in the pre-clinical years of study. They noted that IPE and IPP concepts were not well programmed, health professionals engaged in teaching had poor attitudes towards IPE and IPP, there were limited numbers of skilled health care workers to implement IPP and there was poor communication between students and teaching health professionals. Majority of teaching health professionals noted challenges in implementation of IPE such as poor coordination and large student population and major factors influencing ethics and professionalism in healthcare such as limited government support, low pay for the health care workers, disrespect and lack of appreciation of the health workers by the

Several studies have shown significant improvements in the attitudes and perceptions of healthcare professional students toward interprofessional education (IPE) immediately following intervention with IPE courses. However, there remains little evidence on the lasting effects of IPE courses and the long-term influences of these IPE experiences are poorly documented. The purpose of this study is to assess the long-term effects of an intensive, ten-week interprofessional gross anatomy dissection course at McMaster University. Attitudes and perceptions of past participants towards interprofessional learning were evaluated, now that they have started working with other healthcare professionals outside of the IPE course setting. Thirty-four past participants who have clinical experience working in interprofessional settings or are currently working in the healthcare field completed a follow-up questionnaire consisting of a modified Readiness for Interprofessional Learning Scale (RIPLS) and open-ended questions. Quantitative analysis revealed a significant decrease in their attitude towards teamwork and collaboration and respect for other health professions, but a significant improvement in their understanding of roles and responsibilities compared to their results immediately after the IPE intervention. Qualitative analysis of open-ended questions revealed several themes such as developing interprofessional competencies, developing relationships, and remembering the strengths of the IPE dissection course. The results of this study indicate that the IPE experience in anatomy was highly valued by the students and that past participants maintain a clear understanding of their scope of practice, but the reality of clinical practice may have eroded gains made in the program.

Interprofessional education (IPE) continues to gain traction worldwide. Challenges integrating IPE into health profession programmes include finding convenient times, meeting spaces, and level-appropriate assignments for each profession. This article describes the implementation of a 21-month prospective cohort study pilot programme for the Master of Science in nursing family nurse practitioner (FNP) and doctor of pharmacy (PharmD) students at a private university in the United States. This IPE experience utilised a blended approach for the learning activities; these students had initial and final sessions where they met face-to-face, with asynchronous online activities between these two sessions. The online assignments, discussions, and quizzes during the pilot programme involved topics such as antimicrobial stewardship, hormone replacement therapy, human papilloma virus vaccination, prenatal counselling, emergency contraception, and effects of the Affordable Care Act on practice. The results suggested that the FNP students held more favourable attitudes about online IPE and that the PharmD students reported having a clearer understanding of their own roles and those of the other participating healthcare students. However, the students also reported wanting more face-to-face interaction during their online IPE experience. Implications from this study suggest that effective online IPE can be supported by ensuring educational parity between students regarding the various topics discussed and a consistent approach of the required involvement for all student groups is needed. In addition, given the students desire for more face-to-face interaction, it may be beneficial to offer online IPE activities for a shorter time period. It is anticipated that this study may inform other programmes that are exploring innovative approaches to provide IPE to promote effective collaboration in patient care.

Among children visiting child and adolescent mental health care (CAM), the prevalence of exposure to family violence (FV) is reported to exceed prevalence in community samples, as are potentially traumatic interpersonal events (IPE) outside the family. The aim of the study was to relate CAM patients' self-reported experiences of violence exposure to their current psychiatric symptoms and to compare patients exposed to violence with patients who reported no exposure. We asked 305 consecutive 9- to 17-year-old patients in CAM about their current and previous exposure to violence in and outside of the family. Prevalence of exposure to any kind of violence was 67%. Reported exposures were 19% to IPE, 21% to FV, and 27% to both. Children exposed to both FV and IPE were more negatively affected by the events than children exposed to FV or IPE only. Children in the FV + IPE group reported more mental health symptoms than those in the no violence (33%) group. In general, IPE was related to the outcome measures only in combination with FV. Degree of violence exposure seemed to have a dose-response relationship with the diagnosis of post-traumatic stress disorder. © The Author(s) 2015.

This study investigated the perceptions of deans and faculty members of the Association of Schools of Allied Health Professions (ASAHP) concerning the degree to which their institutions implement and integrate the structural, human resource, political, and symbolic frames or dimensions of interprofessional education (IPE). The study identified correlations among these frames/dimensions, including their relationship with overall IPE program progress and success. This study utilized a nonexperimental comparative descriptive and correlational survey design. The instrument was developed by the researchers and administered online using a readily accessible data collection process. Data were analyzed using descriptive and inferential statistics. Content validity and reliability were established prior to full implementation of the survey. Results revealed high levels of interest but lower levels of progress and success in implementing the various frames/dimensions of IPE. Strong correlations existed between the structural, human resource, political, and symbolic dimensions of IPE, and these dimensions individually and collectively predicted overall IPE program progress and success. The differences between interest and performance raised important questions and led to conclusions about leadership effectiveness, organizational clarity, and the process of implementing the organizational change needed for effective IPE at ASAHP institutions.

The devil is in the details: the seven deadly sins of organizing and continuing interprofessional education in the US.

2011-09-01

In spite of increased calls for expanding interprofessional practice (IPP) in the US health care system to address concerns about patient safety and quality of care, there has not been a corresponding dramatic growth in interprofessional education (IPE) programs. Indeed, the history of IPE in the US has been a roller-coaster ride of gains and losses, successes and failures. Understanding why this has been so requires the development of a personal and political economy framework, based on an understanding of the structural, ideological, and economic factors and forces that characterize IPE in American higher education. Using a metaphor of the seven deadly sins (lust, pride, greed, gluttony, envy, sloth, and wrath), this discussion focuses on both things that should not be done (sins of commission) and those that should be done but are not (sins of omission) to create successful and sustainable IPE programs. Taken together, these factors help to frame a perspective on IPE that highlights the essential knowledge, attitudes, and skills needed by faculty and administrators to create, implement, and - most importantly - sustain successful programs. Implications of this framework for promoting increased IPE are discussed, particularly with respect to insuring its successful continuation into the future.

The increasing demand of a higher level of safety in the operation of the nuclear power plants requires the utilisation of more precise automated equipment to perform in-service inspections. That has been achieved by technological advances in computer technology, in robotics, in examination probe technology with the development of the advanced inspection technique and has also been due to the considerable and varied experience gained in the performance of such inspections. In-service inspection of reactor pressure vessel, especially Russian-designed WWER-1000 presents one of the most important and extensive examination of nuclear power plants primary circuit components. Such examination demand high standards of inspection technology, quality and continual innovation in the field of non-destructive testing advanced technology. A remote underwater contact ultrasonic technique is employed for the examination of the base metal of vessel and reactor welds, whence eddy current method is applied for clad surface examinations. Visual testing is used for examination of the vessel interior. The movement of inspection probes and data positioning are assured by using new reactor pressure vessel tool concept that is fully integrated with inspection systems. The successful performance of reactor pressure vessel is attributed thorough pre-outage planning, training and successful performance demonstration qualification of chosen non-destructive techniques on the specimens with artificial and/or real defects. Furthermore, use of advanced approach of inspection through implementation the state-of-the-art examination equipment significantly reduced the inspection time, radiation exposure to examination personnel, shortening nuclear power plant outage and cutting the total inspection costs. This paper presents advanced approach in the reactor pressure vessel in-service inspections and it is especially developed for WWER-1000 nuclear power plants.(author)

Interprofessional education (IPE) and collaborative practice (CP) have been prolific areas of inquiry exploring research questions mostly concerned with local program and project assessment. The actual sphere of influence of this research has been limited. Often discussed separately, this article places IPE and CP in the same conceptual space. The interface of these form a nexus where new knowledge creation may be facilitated. Rigorous research on IPE in relation to CP that is relevant to and framed by health system reform in the U.S. is the ultimate research goal of the National Center for Interprofessional Practice and Education at the University of Minnesota. This paper describes the direction and scope for a focused and purposive IPECP research agenda linked to improvement in health outcomes, contextualized by health care reform in the U.S. that has provided a revitalizing energy for this area of inquiry. A research agenda articulates a focus, meaningful and robust questions, and a theory of change within which intervention outcomes are examined. Further, a research agenda identifies the practices the area of inquiry is interested in informing, and the types of study designs and analytic approaches amenable to carrying out the proposed work.

Sharp, Randall P; Gales, Barry J; Sirajuddin, Riaz

2018-04-01

Elevated levels of triglycerides are associated with pancreatitis and an increased risk of coronary heart disease. Numerous pharmacologic therapies are available to treat hypertriglyceridemia, including prescription omega-3 fatty acids, which reduce triglyceride levels by 20-50%. Available data indicate the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) may be beneficial for secondary prevention of coronary heart disease. Products containing DHA may increase low-density lipoprotein cholesterol (LDL-C) and, subsequently, coronary heart disease risk. We reviewed prescription omega-3 fatty acid products, of which two-omega-3 acid ethyl esters (OM3EE) and omega-3 carboxylic acid (OM3CA)-contain both DHA and EPA, whereas the other-icosapent ethyl (IPE)-contains EPA only. We identified three retrospective chart reviews and three case reports comparing IPE with OM3EE, whereas two studies compared IPE with placebo. We also reviewed the major studies of OM3EE versus placebo used to gain US FDA approval. LDL-C levels decreased or did not increase significantly in all available studies and case reports in patients receiving the IPE product, with the best data supporting a dose of 4 g per day. The majority of studies only included patients taking IPE concomitantly with statins, but limited data from one study using IPE monotherapy showed a small reduction in LDL-C. Many questions remain regarding IPE, including whether the product reduces cardiovascular events and mortality.

Bednarz, Edward M; Lisi, Anthony J

2014-10-01

Objective : The purpose of this study is to describe the state of chiropractic continuing education vis-à-vis interprofessional education (IPE) with medical doctors (MD) in a survey of a sample of US doctors of chiropractic (DC) and through a review of policies. Methods : Forty-five chiropractors with experience in interprofessional settings completed an electronic survey of their experiences and perceptions regarding DC-MD IPE in chiropractic continuing education (CE). The licensing bodies of the 50 US states and the District of Columbia were queried to assess the applicability of continuing medical education (CME) to chiropractic relicensure. Results : The majority (89.1%) of survey respondents who attend CE-only events reported that they rarely to never experienced MD-IPE at these activities. Survey respondents commonly attended CME-only events, and 84.5% stated that they commonly to very commonly experienced MD-IPE at these activities. More than half (26 of 51) of the licensing bodies did not provide sufficient information to determine if CME was applicable to DC relicensure. Thirteen jurisdictions (25.5%) do not, and 12 jurisdictions (23.5%) do accept CME credits for chiropractic relicensure. Conclusion : The majority of integrated practice DCs we surveyed reported little to no IPE occurring at CE-only events, yet significant IPE occurring at CME events. However, we found only 23.5% of chiropractic licensing bodies allow CME credit to apply to chiropractic relicensure. These factors may hinder DC-MD IPE in continuing education.

Jose Cabrera (Zorita) tube examination

International Nuclear Information System (INIS)

Kuchirka, P.J.

1986-01-01

Jose Cabrera (Zorita) tube examination procedures are discussed. This plant continues to use phosphate water chemistry (sodium/phosphate ratio = 2.1). Three hot leg tube segments were pulled from the Jose Cabera (Zorita) plant in 1985. One tube had a field EC indication on the OD at the first tube support plate and the other two had field EC indications on their ID about 3 inches above the bottom of the tube sheet. All three tubes were initially sent to Battelle for preliminary NDE and decontamination. Segments of two tubes were sent to Westinghouse for destructive examination. The results of the laboratory eddy current and radiographic examinations are given. The results of the visual examinations are also given. The tube with OD indications was destructively examined and shallow intergranular pitting and intergranular attack, up to 2 mils deep, were found on the OD in the tube sheet region. Local areas of IGA, up to 5 mils deep, were found on the OD within the tube support plate region. A summary of this information together with supporting micrographs is given. It was hypothesized that a caustic crevice environment was the cause of this mild degradation. Shallow areas of thinning or wastage, up to 3 mils, were found just above the top of the tube sheet in the sludge pile region. Even more shallow wastage was found at the edges of support plate locations. This wastage is believed to be the remnant of early plant chemistry when a higher sodium/phosphate ratio and higher phosphate concentration were allowed

Developmental origin of the posterior pigmented epithelium of iris.

Iris epithelium is a double-layered pigmented cuboidal epithelium. According to the current model, the neural retina and the posterior iris pigment epithelium (IPE) are derived from the inner wall of the optic cup, while the retinal pigment epithelium (RPE) and the anterior IPE are derived from the outer wall of the optic cup during development. Our current study shows evidence, contradicting this model of fetal iris development. We demonstrate that human fetal iris expression patterns of Otx2 and Mitf transcription factors are similar, while the expressions of Otx2 and Sox2 are complementary. Furthermore, IPE and RPE exhibit identical morphologic development during the early embryonic period. Our results suggest that the outer layer of the optic cup forms two layers of the iris epithelium, and the posterior IPE is the inward-curling anterior rim of the outer layer of the optic cup. These findings provide a reasonable explanation of how IPE cells can be used as an appropriate substitute for RPE cells.

2011-04-01

Interprofessional education (IPE) is a process through which students are provided with learning opportunities with other professions aiming to improve client care. The need to include effective IPE in preregistration programmes for health professionals is increasingly being recognised. The overall aim of the present study was to explore the perceptions and experiences of final-year dietetics students of IPE delivered through interactive online learning groups. A questionnaire was developed to evaluate the students' satisfaction with the IPE modules, including importance to their clinical placements, and their understanding of the roles of other professions. Six dietetics students took part in a focus group that addressed the impact of participating in the IPE modules. The focus group discussion was recorded, transcribed and subjected to content analysis. Twenty students completed the questionnaire (77% of the cohort). Satisfaction with the IPE modules increased as the programme progressed, with 65%, 90% and 95% of the respondents, respectively, being satisfied with the content, assessment and access of the final module. Participating in the programme enhanced the students' opinions on the value of the roles of other professionals (80%) and enhanced their awareness of interprofessional issues (75%). Four key areas of interest emerged from the focus group analysis: key impressions; understanding the role of the dietitian and other professionals; the advantages and disadvantages of online delivery; and interprofessional working in the work environment. The most important outcome of participating in IPE was that students' knowledge of other professions was enhanced, which had a positive impact on placements. An effective information technology infrastructure and appropriate scenarios are key requirements for the online delivery of IPE. © 2011 The Authors.

Interprofessional collaboration is an essential approach to comprehensive patient care. As previous studies have argued, interprofessional education (IPE) must be integrated in a stepwise, systematic manner in undergraduate health profession education programmes. Given this perspective, first-year IPE is a critical opportunity for building the foundation of interprofessional collaborative practice. This study aims to explore the first-year students' learning processes and the longitudinal changes in their perceptions of learning in a year-long IPE programme. Data were collected at a Japanese medical university, in which different pedagogical approaches are adopted in the IPE programme. Some of these approaches include interprofessional problem-based learning, early exposure, and interactive lecture-based teaching. The students are required to submit written reflections as a formative assessment. This study conducted an inductive thematic analysis of 104 written reflections from a series of e-portfolios of 26 first-year students. The themes related to learning outcomes from student perspectives included communication (e.g., active listening and intelligible explanation), teams and teamwork (e.g., mutual engagement and leadership), roles/responsibilities as a group member (e.g., self-directed learning and information literacy), and roles/responsibilities as a health professional (e.g., understanding of the student's own professional and mutual respect in an interprofessional team). The study also indicated three perspectives of students' learning process at different stages of the IPE, i.e., processes by which students became active and responsible learners, emphasised the enhancement of teamwork, and developed their own interprofessional identities. This study revealed the first-year students' learning processes in the year-long IPE programme and clarified the role of the first-year IPE programme within the overall curriculum. The findings suggest that the students

Ideal point error for model assessment in data-driven river flow forecasting

Directory of Open Access Journals (Sweden)

C. W. Dawson

2012-08-01

Full Text Available When analysing the performance of hydrological models in river forecasting, researchers use a number of diverse statistics. Although some statistics appear to be used more regularly in such analyses than others, there is a distinct lack of consistency in evaluation, making studies undertaken by different authors or performed at different locations difficult to compare in a meaningful manner. Moreover, even within individual reported case studies, substantial contradictions are found to occur between one measure of performance and another. In this paper we examine the ideal point error (IPE metric – a recently introduced measure of model performance that integrates a number of recognised metrics in a logical way. Having a single, integrated measure of performance is appealing as it should permit more straightforward model inter-comparisons. However, this is reliant on a transferrable standardisation of the individual metrics that are combined to form the IPE. This paper examines one potential option for standardisation: the use of naive model benchmarking.

Global mechanisms for sustaining and enhancing PES schemes

2010-01-01

An international payment for ecosystem service (IPES) schemes may be one of the only mechanisms available to stimulate the provision of vital non-marketed ecosystem services at the global level, as those nations that benefit from global ecosystem services (GES) cannot readily force other sovereign nations to provide them. Currently, international trade offers trillions of dollars in incentives for countries to convert natural capital into marketable goods and services, and few payments to entice countries to conserve natural capital in order to sustain critical non-marketed ecosystem services. We examine the biophysical characteristics of climate change and biodiversity to understand the obstacles to developing effective IPES schemes. We find that none of the existing schemes for providing GES are adequate, given the scale of the problem. A cap and auction scheme for CO 2 emissions among wealthy nations could fund IPES and simultaneously deter carbon emissions. To disburse funds, we should adapt Brazil's ICMS ecologico, and apportion available funds to targeted countries in proportion to how well they meet specific criteria designed to measure the provision of GES. Individual countries can then develop their own policies for increasing provision of these services, ensured of compensation if they do so. Indirect IPES should include funding for freely available technologies that protect or provide GES, such as the low carbon energy alternatives that will be essential for curbing climate change. Markets rely on the price mechanism to generate profits, which rations technology to those who can afford it, reducing adoption rates, innovation and total value. (author)

Moderating the stereotypical views of health and social care students: the role of interprofessional education.

Foster, Rebecca; Macleod Clark, Jill

2015-01-01

The potential of interprofessional education (IPE) to influence the perceptions and attitudes of health and social care professionals towards their colleagues in other disciplines is well recognized. However, empirical evidence for the positive impact of IPE on stereotypical beliefs has been limited. We report the findings of a pioneering, large scale study designed to assess the influence of IPE on these beliefs. A pre-test, post-test, quasi experimental design compared students' stereotypical views at the beginning and end of undergraduate studies. 580 students from 10 health and social care professional groups undertook assessed IPE modules over 3 years (the intervention group). Baseline and post-course stereotype ratings were compared with those of 672 students in a comparison group, not exposed to IPE modules. Baseline stereotype profiles showed clear variations in the way different professions were perceived, indicating stereotypical beliefs about the characteristics of each profession. Rating patterns were similar for intervention and comparison groups. At graduation, only minor changes were observed in the overall rating patterns for both groups. However, more ratings had decreased in the intervention group than the comparison group, suggesting that IPE may play a role in moderating more extreme stereotyping of colleagues in other professions.

Teamwork and collaboration are regarded as important goals for health and social care education and inter-professional education (IPE) the vehicle to achieve this. However, there is debate concerning the best strategies for implementation, location and delivery of IPE. This exploratory study was undertaken to anticipate some of the problems of implementing a pre-qualification IPE programme for Children's Branch nursing students and medical students undertaking a Paediatrics module and to identify strategies to maximise success. A modified version of the readiness for inter-professional learning scale (RIPLS), including additional open-ended questions, was used with a convenient, purposeful sample of 20 medical and 10 nursing students. Both groups regarded learning team-working skills as important. Medical students regarded IPE as a means to learn about team-work and professional roles otherwise they indicated a preference for a discipline-based approach. Both groups were found to have acquired a strong sense of their own professional role. Both perceived IPE as disadvantageous if it impeded their own professional learning. Results also highlighted the importance of class size, stage of learning, appropriate skills and subject in IPE planning. We conclude that a small exploratory study can provide a useful guide for programme planning and additional qualitative data can enable a more comprehensive explanation of results.

Farlow, Janice L; Goodwin, Charles; Sevilla, Javier

2015-05-01

The academic community must replicate and strengthen existing models for interprofessional education (IPE) to meet widespread calls for team-based patient-centered care. One effective but under-explored possibility for IPE is through student-led clinics, which now exist in the majority of medical schools. This short report presents the Indiana University Student Outreach Clinic (IU-SOC), which involves seven different professional programs across three institutions, as a model for how IPE can be delivered formally through service learning. Lessons learned, such as nurturing an intentional interprofessional program, structured orientation and reflection, and resource and knowledge sharing between the clinic and academic institutions, can be applied to all student-led clinics, but also can inform other IPE initiatives in health professional curricula.

Looking Back to Move Ahead: Interprofessional Education in Dental Education.

Hamil, Lindsey M

2017-08-01

Interprofessional education (IPE) is a widely recognized and critical component of dental and health professions education and is included in two of the predoctoral education standards required by the Commission on Dental Accreditation (CODA). Following a review of the literature on the state of IPE education in U.S. dental education programs, this article revisits six institutions identified in previous research as exemplars successfully implementing IPE on their campuses. Interviews were conducted with leaders at the following programs: Columbia University, Medical University of South Carolina, University of Colorado Anschutz Medical Campus, University of Florida, University of Minnesota, and Western University of Health Sciences. Strengths and weakness of IPE in dental education are discussed, along with opportunities for the future including reducing barriers to scheduling, increasing intraprofessional education, and consistent outcomes assessment. The article concludes with lessons learned by administrators and suggestions for improving incorporation of these requirements into predoctoral dental education programs by emphasizing the importance of IPE and dentistry's role in overall health. This article was written as part of the project "Advancing Dental Education in the 21 st Century."

Identification of the Gene Encoding Isoprimeverose-producing Oligoxyloglucan Hydrolase in Aspergillus oryzae*

Matsuzawa, Tomohiko; Mitsuishi, Yasushi; Kameyama, Akihiko

2016-01-01

Aspergillus oryzae produces a unique β-glucosidase, isoprimeverose-producing oligoxyloglucan hydrolase (IPase), that recognizes and releases isoprimeverose (α-d-xylopyranose-(1→6)-d-glucopyranose) units from the non-reducing ends of oligoxyloglucans. A gene encoding A. oryzae IPase, termed ipeA, was identified and expressed in Pichia pastoris. With the exception of cellobiose, IpeA hydrolyzes a variety of oligoxyloglucans and is a member of the glycoside hydrolase family 3. Xylopyranosyl branching at the non-reducing ends was vital for IPase activity, and galactosylation at a α-1,6-linked xylopyranosyl side chain completely abolished IpeA activity. Hepta-oligoxyloglucan saccharide (Xyl3Glc4) substrate was preferred over tri- (Xyl1Glc2) and tetra- (Xyl2Glc2) oligoxyloglucan saccharides substrates. IpeA transferred isoprimeverose units to other saccharides, indicating transglycosylation activity. The ipeA gene was expressed in xylose and xyloglucan media and was strongly induced in the presence of xyloglucan endo-xyloglucanase-hydrolyzed products. This is the first study to report the identification of a gene encoding IPase in eukaryotes. PMID:26755723

Status of IGA in Japanese plants and results of S/G pulled tube examinations

International Nuclear Information System (INIS)

Takamatsu, H.

1986-01-01

Currently there are 14 operating PWRs in Japan. Five of the plants have been affected by the intergranular stress corrosion cracking (IGSCC). The experience of the 14 plants with regard to tube plugging is summarized. The five affected plants are: Mihama 2, Takahama 1, Takahama 2, Ohi 1 and Genkai 1. The first two plants experienced IGSCC in the tube sheet crevice region (55 and 124 tubes plugged) and a slight problem with IGSCC in tube support plate crevices (13 and 8 tubes plugged). The other three plants have experienced extensive IGSCC in their tube support plate crevices (1330, 773 and 667 tubes plugged, respectively). The Japanese consider that their IGSCC (IGA) problem is caused by a combination material and environmental factors. All three factors must be present for attack to take place. If the two environmental factors can be controlled, then the attack will stop. The preventive measures being employed by the Japanese are given. These include: prevention of free caustic (i.e., sludge lancing, crevice cleaning, boron injection and improvement in water treatment) and maintenance of deoxidation environment (i.e., hydrazine soaking before operation and enriching the concentration of hydrazine in the secondary water)

The rationale for Interprofessional Education (IPE) is based on the assumption it will improve practice. Despite evidence that it may modify attitudes and provide knowledge and skills for collaboration, there is little evidence about whether these skills can be transferred to practice. The aim of this research was to explore how midwifery students apply pre-qualification IPE learning to practice and to understand the factors in the clinical workplace that facilitate or hinder this application. A purposive sample of students, educators, Heads of Midwifery and new midwives from four universities throughout the United Kingdom participated in semi-structured interviews and focus groups. Emerging themes were developed using the principles of Grounded Theory. Participants articulated ways in which the clinical environment either promoted or prevented IPE in practice. The extent to which the clinical institution promoted IPE was made visible through the support for students during placements; the support for new midwives; and the evolution of professional roles. Buy-in for the IPE agenda in the workplace influences the ability of new midwives to apply IPE competencies to professional practice. The benefits of a theoretical foundation in interprofessional skills may be lost if students and new midwives find themselves working in contexts that do not make collaboration a priority.

Despite the crucial role of carbon transport in whole plant physiology and its impact on plant-environment interactions and ecosystem function, relatively little research has tried to examine how phloem physiology impacts plant ecology. In this review, we highlight several areas of active research where inquiry into phloem physiology has increased our understanding of whole plant function and ecological processes. We consider how xylem-phloem interactions impact plant drought tolerance and reproduction, how phloem transport influences carbon allocation in trees and carbon cycling in ecosystems and how phloem function mediates plant relations with insects, pests, microbes and symbiotes. We argue that in spite of challenges that exist in studying phloem physiology, it is critical that we consider the role of this dynamic vascular system when examining the relationship between plants and their biotic and abiotic environment. © 2015 John Wiley & Sons Ltd.

2015-01-01

Full Text Available Objective: The purpose of this study was to evaluate health professions students’ understanding of their own and others’ roles on interprofessional (IP teams, assess students’ perceptions of their preparedness to practice in an IP team, and determine differences by type of learning institution and participation in interprofessional education (IPE. Methods: Medical, nursing, and pharmacy students at three Ohio universities with unique IP learning models were surveyed. Descriptive statistics, analysis of variance (ANOVA, chi-square, and two sample t- tests were used to compare measures of knowledge, IPE participation, and preparedness. Results: Of the 981 invited students, 273 completed the survey (27.8% response. Overall, 70.7% of participants felt prepared to work on an IP team. Those who reported participation in IPE were more likely to feel prepared to practice on an IP team compared to those who did not (76.8% [149/194] vs. 55.3% [42/76], p=0.0005. Participation in IPE did not significantly affect knowledge scores (participators 79.6% vs. non-participators 81.0%, p=0.1731. Those who had higher profession-specific knowledge scores were more likely to feel prepared to work with that specific profession. Conclusions: Participation in IPE activities in the representative institutions was high, as was knowledge of professional roles. Both participation in IPE and increased knowledge of roles were associated with increased student-assessed preparedness. Advancement of skills and behaviors including knowledge of roles and other competencies may all be important. Pharmacy in particular should prioritize IPE as a means to elucidate our role on the patient care team.   Type: Original Research

Examine outcomes for the National Parkinson Foundation (NPF) Allied Team Training for Parkinson (ATTP), an interprofessional education (IPE) program in Parkinson's disease (PD) and team-based care for medicine, nursing, occupational, physical and music therapies, physician assistant, social work and speech-language pathology disciplines. Healthcare professionals need education in evidence-based PD practices and working effectively in teams. Few evidence-based models of IPE in PD exist. Knowledge about PD, team-based care, the role of other disciplines and attitudes towards healthcare teams were measured before and after a protocol-driven training program. Knowledge, attitudes and practice changes were again measured at 6-month post-training. Trainee results were compared to results of controls. Twenty-six NPF-ATTP trainings were held across the U.S. (2003-2013). Compared to control participants (n = 100), trainees (n = 1468) showed statistically significant posttest improvement in all major outcomes, including self-perceived (p < 0.001) and objective knowledge (p < 0.001), Understanding Role of Other Disciplines (p < 0.001), Attitudes Toward Health Care Teams Scale (p < 0.001), and the Attitudes Toward Value of Teams (p < 0.001) subscale. Despite some decline, significant improvements were largely sustained at six-month post-training. Qualitative analyses confirmed post-training practice changes. The NPF-ATTP model IPE program showed sustained positive gains in knowledge of PD, team strategies and role of other disciplines, team attitudes, and important practice improvements. Further research should examine longer-term outcomes, objectively measure practice changes and mediators, and determine impact on patient outcomes. Copyright © 2015 Elsevier Ltd.

Ebisawa, Katsumi; Hibino, Kenta

2008-01-01

The Advanced Safety Examination Guideline for Seismic Design for Nuclear Power Plant (the advanced safety examination guideline) was worked out on September 19, 2006. In this paper, a summary of the method of probability theory in the advanced safety examination guideline and the Seismic PSA Implementation Standards is stated. On utilization of the probability theory for the advanced safety examination guideline, the uncertainty resulting from the process of the decision of the basic design earthquake ground motion (Ss) is stated to be considered using the proper method. The references of the extra probability for evaluation of earthquake hazard and combination of the working load and the earthquake load are stated. Definition, evaluation method and effort to lower the 'residual risks', and relation between the residual risks and the extra probability of Ss are described. A summary of the earthquake-resistant design for nuclear power facilities is explained by the old guideline. (S.Y.)

Anisotropic Intervalley Plasmon Excitations in Graphene

International Nuclear Information System (INIS)

Chen Jian; Xu Huai-Zhe

2015-01-01

We investigate theoretically the intervalley plasmon excitations (IPEs) in graphene monolayer within the random-phase approximation. We derive an analytical expression of the real part of the dielectric function. We find a low-energy plasmon mode with a linear anisotropic dispersion which depends on the Fermi energy and the dielectric constant of substrate. The IPEs show strongly anisotropic behavior, which becomes significant around the zigzag crystallographic direction. More interestingly, the group velocity of IPE varies from negative to positive, and vanishes at special energy. (paper)

Safety and design impact of hurricane Andrew

International Nuclear Information System (INIS)

Guey, Ching N.

2004-01-01

Turkey Point completed the IPE in June of 1991. Hurricane Andrew landed at Turkey Point on August 24, 1992. Although the safety related systems, components and structures were not damaged by the Hurricane Andrew, certain nonsafety related components and the neighboring fossil plant sustained noticeable damage. Among the major components that were nonsafety related but would affect the PRA of the plant included the service water pumps and the high tower. This paper discusses the safety and design impact of Hurricane Andrew on Turkey Point Nuclear Power Plant. The risk of hurricanes on the interim and evolving plant configurations are briefly described. The risk of the plant from internal events as a result of damage incurred during Hurricane Andrew are discussed. The design change as the result of Hurricane Andrew and its impact on the PRA are presented. (author)

Efficiency Limits of Solar Energy Harvesting via Internal Photoemission in Carbon Materials

Directory of Open Access Journals (Sweden)

Svetlana V. Boriskina

2018-02-01

Full Text Available We describe strategies to estimate the upper limits of the efficiency of photon energy harvesting via hot electron extraction from gapless absorbers. Gapless materials such as noble metals can be used for harvesting the whole solar spectrum, including visible and near-infrared light. The energy of photo-generated non-equilibrium or ‘hot’ charge carriers can be harvested before they thermalize with the crystal lattice via the process of their internal photo-emission (IPE through the rectifying Schottky junction with a semiconductor. However, the low efficiency and the high cost of noble metals necessitates the search for cheaper abundant alternative materials, and we show here that carbon can serve as a promising IPE material candidate. We compare the upper limits of performance of IPE photon energy-harvesting platforms, which incorporate either gold or carbon as the photoactive material where hot electrons are generated. Through a combination of density functional theory, joint electron density of states calculations, and Schottky diode efficiency modeling, we show that the material electron band structure imposes a strict upper limit on the achievable efficiency of the IPE devices. Our calculations reveal that graphite is a good material candidate for the IPE absorber for harvesting visible and near-infrared photons. Graphite electron density of states yields a sizeable population of hot electrons with energies high enough to be collected across the potential barrier. We also discuss the mechanisms that prevent the IPE device efficiency from reaching the upper limits imposed by their material electron band structures. The proposed approach is general and allows for efficient pre-screening of materials for their potential use in IPE energy converters and photodetectors within application-specific spectral windows.

Interprofessional educator ambassadors: An empirical study of motivation and added value.

Science.gov (United States)

Anderson, Elizabeth Susan; Thorpe, Lucy Nicola

2010-01-01

Interprofessional education (IPE) is being led by a driving force of teaches who advocate for the importance of this learning within health and social care professional curriculum. Many of these leaders have additional uni professional teaching responsibilities. This study aimed to explore the impact of leading an IPE curriculum on teachers, who were at the forefront of establishing a new IPE curriculum in the east midlands, UK. The prospective study used the principles of grounded theory to analyse the educator's experiences. The study included teachers who work from academic university posts and those who teach from within practice. These IPE leaders were identified through their involvement in the design and delivery of the local IPE initiatives. They were invited to share their experiences at either a mixed-discipline focus group, a one-to-one interview or by completing a postal/e questionnaire. During analysis the views from each data set were triangulated. A total of 58 educators shared their experiences. All benefitted from being part of the planning and teaching teams. They were driven by a strong belief that IPE had the potential to improve patient care and that future healthcare practice would remain team based. Engagement had brought additional benefits to their teaching and career development in particular through forming new relationships with colleagues from other caring professions. They were concerned about educators teaching interprofessional student groups with little prior experience of IPE. The data suggest educators who take on a leading developmental role in designing and delivering an interprofessional curriculum benefit personally and professionally through working relationships with colleagues in other professions and through teaching wider networks of students. These new insights strengthen personal practice and research and in turn have the potential to influence and improve the quality of faculty teaching.

Differential protective effects of immune lymphoid cells against transplanted line Ib leukemia and immune polioencephalomyelitis. [X radiation, mice

Energy Technology Data Exchange (ETDEWEB)

Duffey, P.S.; Lukasewycz, O.A.; Olson, D.S.; Murphy, W.H.

1978-12-01

The capacity of immune cells obtained from the major lymphoid compartments to protect C58 mice from transplanted line Ib leukemia, and from an age-dependent autoimmune CNS disease (immune polioencephalomyelitis = IPE) elicited by immunizing old C58 mice with inactivated Ib cells was quantified. Cells used for comparative adoptive protection tests were harvested from the major lymphoid compartments 14 to 15 days after young C58 mice were immunized with inactivated Ib cell preparations. Regression curves were plotted from survival data and the log/sub 10/PD/sub 50/ values were determined. Immune spleen (ISC) and peritoneal cells (IPEC) were significantly more protective against transplanted Ib cells than immune lymph node (ILNC), thymic (ITC), and marrow cells (IMC). In contrast, IPEC and IMC were not protective against IPE and ITC were only marginally protective. ILNC afforded significant protection to transplantable leukemia but were only marginally protective to IPE. When ISC were treated with anti-thy 1.2 serum and complement, protection against transplanted leukemia and IPE was reduced > 99%. When donors of immune lymphoid cells were treated with 12.5 mg of cortisone acetate daily for 2 days before lymphoid cells were harvested, protection against transplanted Ib cells by ISC was reduced by approximately 90% whereas protection against IPE was totally eliminated. Considered together, these results indicate that the protective mechanisms to transplantable leukemia and IPE differ significantly in the same indicator mouse strain.

The power of prepositions: learning with, from and about others in the context of interprofessional education.

Science.gov (United States)

Bainbridge, Lesley; Wood, Victoria Isobel

2012-11-01

This paper is the first of a two-part series. It presents a research study that aimed to provide a more contextual description of the commonly applied definition of interprofessional education (IPE) offered in 2002 by the Centre for the Advancement of Interprofessional Education (CAIPE) in the UK: "when two or more professions learn with, from and about each other to improve collaboration and quality of care." The study confirmed and consolidated key characteristics of IPE by exploring the meaning of with, from and about. The words with, from and about were regarded as complex. Words describing learning with each other included active engagement, co-location and equally valued. Concepts linked to learning about included knowing about people outside their professional role and interaction. Learning from others was characterized by trust, respect and confidence in others' knowledge. Although learning about others was described as the first part of learning with, from and about, there were mixed views on whether learning with or from formed the second part of the definition. Based on this work, the second paper in this series presents a proposed taxonomy for IPE that may serve to inform emerging applications for IPE in the context of education, service delivery and policy. This research contributes to an emerging understanding of IPE that will support competency development and sound curriculum design, continuing professional development and evaluation of the impact of IPE and collaboration on health outcomes.

Stereotyping at the undergraduate level revealed during interprofessional learning between future doctors and biomedical scientists.

Lewitt, Moira S; Ehrenborg, Ewa; Scheja, Max; Brauner, Annelie

2010-01-01

Interprofessional education (IPE) involving undergraduate health professionals is expected to promote collaboration in their later careers. The role of IPE between doctors and biomedical scientists has not been explored at the undergraduate level. Our aim was to introduce IPE sessions for medical and biomedical students in order to identify the benefits and barriers to these groups learning together. Medical and biomedical students together discussed laboratory results, relevant literature, and ideas for developing new diagnostic tools. The programme was evaluated with questionnaires and interviews. While there was general support for the idea of IPE, medical and biomedical students responded differently. Biomedical students were more critical, wanted more explicit learning objectives and felt that their professional role was often misunderstood. The medical students were more enthusiastic but regarded the way the biomedical students communicated concerns about their perceived role as a barrier to effective interprofessional learning. We conclude that stereotyping, which can impede effective collaborations between doctors and biomedical scientists, is already present at the undergraduate level and may be a barrier to IPE. Effective learning opportunities should be supported at the curriculum level and be designed to specifically enable a broad appreciation of each other's future professional roles.

Designing learning spaces for interprofessional education in the anatomical sciences.

Cleveland, Benjamin; Kvan, Thomas

2015-01-01

This article explores connections between interprofessional education (IPE) models and the design of learning spaces for undergraduate and graduate education in the anatomical sciences and other professional preparation. The authors argue that for IPE models to be successful and sustained they must be embodied in the environment in which interprofessional learning occurs. To elaborate these arguments, two exemplar tertiary education facilities are discussed: the Charles Perkins Centre at the University of Sydney for science education and research, and Victoria University's Interprofessional Clinic in Wyndham for undergraduate IPE in health care. Backed by well-conceived curriculum and pedagogical models, the architectures of these facilities embody the educational visions, methods, and practices they were designed to support. Subsequently, the article discusses the spatial implications of curriculum and pedagogical change in the teaching of the anatomical sciences and explores how architecture might further the development of IPE models in the field. In conclusion, it is argued that learning spaces should be designed and developed (socially) with the expressed intention of supporting collaborative IPE models in health education settings, including those in the anatomical sciences. © 2015 American Association of Anatomists.

Simic, Z.; Mikulicic, V.; Vukovic, I.

2004-01-01

The paper describes work performed for the Nuclear Power Station (NPS). Work is related to the periodic initiating events frequency update for the Probabilistic Safety Assessment (PSA). Data for all relevant NPS initiating events (IE) were reviewed. The main focus was on events occurring during most recent operating history (i.e., last four years). The final IE frequencies were estimated by incorporating both NPS experience and nuclear industry experience. Each event was categorized according to NPS individual plant examination (IPE) initiating events grouping approach. For the majority of the IE groups, few, or no events have occurred at the NPS. For those IE groups with few or no NPS events, the final estimate was made by means of a Bayesian update with general nuclear industry values. Exceptions are rare loss-of-coolant-accidents (LOCA) events, where evaluation of engineering aspects is used in order to determine frequency.(author)

Development of high-energy resolution inverse photoemission technique

Asakura, D.; Fujii, Y.; Mizokawa, T.

2005-01-01

We developed a new inverse photoemission (IPES) machine based on a new idea to improve the energy resolution: off-plane Eagle mounting of the optical system in combination with dispersion matching between incoming electron and outgoing photon. In order to achieve dispersion matching, we have employed a parallel plate electron source and have investigated whether the electron beam is obtained as expected. In this paper, we present the principle and design of the new IPES method and report the current status of the high-energy resolution IPES machine

Optical study of HgCdTe infrared photodetectors using internal photoemission spectroscopy

Lao, Yan-Feng; Unil Perera, A. G.; Wijewarnasuriya, Priyalal S.

2014-01-01

We report a study of internal photoemission spectroscopy (IPE) applied to a n-type Hg 1−x Cd x Te/Hg 1−y Cd y Te heterojunction. An exponential line-shape of the absorption tail in HgCdTe is identified by IPE fittings of the near-threshold quantum yield spectra. The reduction of quantum yield (at higher photon energy) below the fitting value is explained as a result of carrier-phonon scatterings. In addition, the obtained bias independence of the IPE threshold indicates a negligible electron barrier at the heterojunction interface

2015-05-01

This report explores the relevance of gaming in IPE curriculum design with the use of the Interprofessional Education Game (iPEG) as an activity aimed to achieve positive interprofessional learning outcomes for students. It was designed to enable the understanding of professional roles and responsibilities in patient/client care settings. We provide a description of its implementation and evaluation with first year student cohorts (900+ per cohort) over a 3-year period within an established interprofessional education (IPE) programme. The game encapsulates fun and memorable learning styles to explore professional stereotypes and team approaches to care delivery. It can be a valuable teaching tool for those designing IPE curriculum. Evaluation data from students and staff were mainly positive. We discuss the use of the game and its potential to be adapted in flexible and creative ways to assist educators in consider incorporating gaming within their own IPE programmes.

Reflecting on reflection in interprofessional education: implications for theory and practice.

Science.gov (United States)

Clark, Phillip G

2009-05-01

Interprofessional education (IPE) involves learning, and learning requires reflection. Educators need to "reflect more on reflection" if they are to be effective teachers in ensuring the learning outcomes essential for teamwork and interprofessional practice (IPP), including incorporating both theory and practice into the development of educational interventions. First, this discussion surveys the IPE-relevant literature on reflection, and then defines and refines the multidimensional concept of reflection as it relates to IPE in developing and implementing teamwork learning programs and experiences. Second, specific methods to promote reflection are presented and explored, including self-assessments, journaling, and written papers. Actual samples from student journals and assignments provide examples of the impacts of using these methods on participant reflection and learning. Finally, implications for an expanded understanding and application of reflection for IPE will be discussed, and recommendations made for educational practice and research in this area.

An interprofessional education Russian cultural competence course: Implementation and follow-up perspectives.

Topping, Daniel

2015-01-01

Health sciences educators are faced with creating meaningful, effective and satisfying experiences in interprofessional education (IPE) and cultural competence (CC) required of both students and professionals in practice. This study evaluated the experience and attitudes of the participants in a course combining IPE and CC. A novel, interprofessional course in the Russian language and culture was developed and delivered to a group of medical, nursing, and pharmacy students. One year after the completion of the course, an anonymous, online survey was sent to the participants. Attitudes, comfort, self-efficacy in working with other cultures/healthcare professionals, and comparison of the course to other IPE activities were assessed. The survey suggested that the course was a satisfying and effective combination of IPE and CC in a pre-professional health educational setting. Further work could be undertaken to evaluate the experiences of similar activities in the professional and continuing education arenas.

2017-01-01

Information system research has stressed the importance of theory in understanding how user perceptions can motivate the use and adoption of technology such as web-based continuing professional development programs for interprofessional education (WCPD-IPE). A systematic review was conducted to provide an information system perspective on the current state of WCPD-IPE program evaluation and how current evaluations capture essential theoretical constructs in promoting technology adoption. Six databases were searched to identify studies evaluating WCPD-IPE. Three investigators determined eligibility of the articles. Evaluation items extracted from the studies were assessed using the Kirkpatrick-Barr framework and mapped to the Benefits Evaluation Framework. Thirty-seven eligible studies yielded 362 evaluation items for analysis. Most items (n = 252) were assessed as Kirkpatrick-Barr level 1 (reaction) and were mainly focused on the quality (information, service, and quality) and satisfaction dimensions of the Benefits Evaluation. System quality was the least evaluated quality dimension, accounting for 26 items across 13 studies. WCPD-IPE use was reported in 17 studies and its antecedent factors were evaluated in varying degrees of comprehensiveness. Although user reactions were commonly evaluated, greater focus on user perceptions of system quality (ie, functionality and performance), usefulness, and usability of the web-based platform is required. Surprisingly, WCPD-IPE use was reported in less than half of the studies. This is problematic as use is a prerequisite to realizing any individual, organizational, or societal benefit of WCPD-IPE. This review proposes an integrated framework which accounts for these factors and provides a theoretically grounded guide for future evaluations.

Nondestructive examination requirements for PWR vessel internals

International Nuclear Information System (INIS)

Spanner, J.

2015-01-01

This paper describes the requirements for the nondestructive examination of pressurized water reactor (PWR) vessel internals in accordance with the requirements of the EPRI Material Reliability Program (MRP) inspection standard for PWR internals (MRP-228) and the American Society of Mechanical Engineers Section XI In-service Inspection. The MRP vessel internals examinations have been performed at nuclear plants in the USA since 2009. The objective of the inspection standard is to provide the requirements for the nondestructive examination (NDE) methods implemented to support the inspection and evaluation of the internals. The inspection standard contains requirements specific to the inspection methodologies involved as well as requirements for qualification of the NDE procedures, equipment and personnel used to perform the vessel internals inspections. The qualification requirements for the NDE systems will be summarized. Six PWR plants in the USA have completed inspections of their internals using the Inspection and Evaluation Guideline (MRP-227) and the Inspection Standard (MRP-228). Examination results show few instances of service-induced degradation flaws, as expected. The few instances of degradation have mostly occurred in bolting

The argument for integrating interprofessional education (IPE) activities into the workplace has been made concurrently with the call for collaborative clinical practice. An exploratory case study investigation of existing activities in a large metropolitan health care network was undertaken to inform the development of future IPE initiatives. Purposive sampling invited clinicians involved in the design or delivery of workplace IPE activities to participate in a semi-structured interview to discuss their existing programs and the opportunities and challenges facing future work. Interviews were audiotaped, transcribed and thematically analysed. In total, 15 clinicians were interviewed representing medicine, nursing, occupational therapy, pharmacy, physiotherapy, psychology, social work and speech pathology. The IPE programs identified included one medical and midwifery student workshop, several dedicated new graduate or intern programs combining the professions and multiple continuing professional development programs. Three dominant themes were identified to inform the development of future work: clinician factors, organisational factors and IPE considerations. In addition to the cultural, physical and logistical challenges associated with education that integrates professions in the workplace, the time required for the design and delivery of integrated team training should be accounted for when establishing such programs. Considerations for sustainability include ongoing investment in education skills for clinicians, establishment of dedicated education roles and expansion of existing education activities.

The aim of this study was to evaluate the attitudes towards physician-pharmacist collaboration among pharmacy students in order to develop an interprofessional education (IPE) opportunity through integrating cooperative learning (CL) into a team-based student-supported community service event. The study also aimed to assess the change in students' attitudes towards interprofessional collaboration after participation in the event. A bilingual version of the Scale of Attitudes Toward Physician-Pharmacist Collaboration (SATP(2)C) in English and Chinese was completed by pharmacy students enrolled in Wuhan University of Science and Technology, China. Sixty-four students (32 pharmacy students and 32 medical students) in the third year of their degree volunteered to participate in the IPE opportunity for community-based diabetes and hypertension self-management education. We found the mean score of SATP(2)C among 235 Chinese pharmacy students was 51.44. Cronbach's alpha coefficient was 0.90. Our key finding was a significant increase in positive attitudes towards interprofessional collaboration after participation in the IPE activity. These data suggest that there is an opportunity to deliver IPE in Chinese pharmacy education. It appears that the integration of CL into an interprofessional team-based community service offers a useful approach for IPE.

The introduction of a transformative technology into practice settings can affect the functioning of interprofessional teams, placing stress on interprofessional relationships, thus slowing adoption and change. This study explored the potential of an interprofessional education (IPE) approach to mediate this stress and facilitate the adoption of a transformative technology- Image Guided Radiation Therapy (IGRT). Oncologists, physicists, and therapists in radiation medicine who attended an interprofessional IGRT Education Course were interviewed about perceived benefits and stressors to IPE and to interprofessional practice (IPP) in the IGRT context. A modified grounded theory approach was used to conduct 14 interviews, with 200 minutes of interview time recorded. In introducing IGRT, participants noted interprofessional stress in understanding and adopting new technology. IPE offered common terminology, appreciation for others' knowledge, and a holistic framework for practice. Outcomes were thought to foster collaboration, efficiency, and improved professional role definition. Time constraints and power relations were noted to be residual stressors exacerbated by IPE, but were thought to be transient. IPE can thus be of benefit in the implementation of transformative technologies such as IGRT, through mediation of interprofessional stress inherent in change. Interprofessional knowledge, collaboration, and efficiency in practice facilitate the development and adoption of a new practice model.

Steketee, Carole; Forman, Dawn; Dunston, Roger; Yassine, Tagrid; Matthews, Lynda R; Saunders, Rosemary; Nicol, Pam; Alliex, Selma

2014-05-01

This paper reports on three interrelated Australian studies that provide a nationally coherent and evidence-informed approach to interprofessional education (IPE). Based on findings from previous studies that IPE tends to be marginalized in mainstream health curriculum, the three studies aspired to produce a range of resources that would guide the sustainable implementation of IPE across the Australian higher education sector. Nine national universities, two peak industry bodies and a non-government organization constituted the study team. Data were gathered via a mixture of stakeholder consultations, surveys and interviews and analyzed using quantitative and qualitative methods. An important outcome was a curriculum renewal framework which has been used to explore the implications of the study's findings on Australian nursing. While the findings are pertinent to all health professions, nursing is well placed to take a leading role in establishing IPE as a central element of health professional education.

2017-03-01

The ability of health professionals to collaborate effectively has significant potential impact on patient safety and quality-care outcomes, especially given the increasingly complex and dynamic clinical practice environments of today. Educators of the health professions are faced with an immediate challenge to adapt curricula and traditional teaching methods to ensure graduates are equipped with the necessary interprofessional competencies and (inter)professional values for their future practice. The World Health Organization's "Framework for action in interprofessional education (IPE) and collaborative practice" promotes IPE as a key strategy to enhance patient outcomes by preparing a "collaborative practice-ready health workforce." Logistical and attitudinal barriers can hinder integration of IPE into curricula. Lessons learned through the implementation of a planned change to establish four interprofessional seminars (team communication, medical error communication, healthcare English, and small business management) at Heidelberg University Medical Faculty, Germany, are described. A key factor in successfully anchoring IPE seminars in the undergraduate curricula was the structured approach drawing on change management concepts.

Castrèn, M; Mäkinen, M; Nilsson, J; Lindström, V

2017-05-01

The aim of the study was to investigate whether interprofessional education (IPE) and interprofessional collaboration (IPC) during the educational program had an impact on prehospital emergency care nurses' (PECN) self-reported competence towards the end of the study program. A cross-sectional study using the Nurse Professional Competence (NPC) Scale was conducted. A comparison was made between PECN students from Finland who experienced IPE and IPC in the clinical setting, and PECN students from Sweden with no IPE and a low level of IPC. Forty-one students participated (Finnish n=19, Swedish n=22). The self-reported competence was higher among the Swedish students. A statistically significant difference was found in one competence area; legislation in nursing and safety planning (pprofessional competence was relatively low according to the NPC Scale. Increasing IPC and IPE in combination with offering a higher academic degree may be an option when developing the ambulance service and the study program for PECNs. Copyright © 2017 Elsevier Ltd.

Nilüfer KARACASULU

2009-10-01

Full Text Available The aim of this article is to inclusively analyze the debates on hegemonic order, also taking into consideration recent critical thoughts in international political economy (IPE. In the first section, the three conceptions of classical IPE, which are liberalism, Marxism and mercantilism, and their notions of hegemony are explained. Gramscians have developed critical views on hegemony, which contradicts to the classical hegemony approach. In the second section, the meaning of hegemony as developed by Antonio Gramsci, which is different than classical conceptions, as well as the conceptual framework developed by his follower Robert W. Cox are explained. Lastly, as the contemporary priorities and challenges of neo-Gramscian perspectives in IPE studies are given, similarities and differences are indicated. As a conclusion, when the notion of hegemonic order in international realm is considered as a relation between social forces-state structures-world order, which is different than traditional approaches, it brings a new aspect to the contemporary discussions on globalization in IPE.

Understanding interprofessional education as an intergroup encounter: The use of contact theory in programme planning.

Science.gov (United States)

Carpenter, John; Dickinson, Claire

2016-01-01

A key underlying assumption of interprofessional education (IPE) is that if the professions are brought together they have the opportunity to learn about each other and dispel the negative stereotypes which are presumed to hamper interprofessional collaboration in practice. This article explores the application of contact theory in IPE with reference to eight evaluation studies (1995-2012) which adopted this theoretical perspective. It proposes that educators should pay explicit attention to an intergroup perspective in designing IPE programmes and specifically to the "contact variables" identified by social psychologists studying intergroup encounters. This would increase the chances of the planned contact having a positive effect on attitude change.

Ultra violet inverse photoelectron spectroscopy (uv-ipes) is a powerful technique for the investigation of alkali metals on metal surfaces because most of the alkali metal show chemical and physical properties, which are related to their unoccupied states. In this study, it is found that the uv-ipes spectra provides the intensity of the unoccupied states which decreases with increasing na coverage at off-normal incidence of the electron beam. It is also found that the uv-ipes spectra at 17 and 19 ev incident electron energies presents a shift toward fermi level on the peak at ∼7.8 ev with increasing na coverage

Examining an underappreciated control on lignin decomposition in soils? Effects of reactive manganese species on intact plant cell walls

Science.gov (United States)

Keiluweit, M.; Bougoure, J.; Pett-Ridge, J.; Kleber, M.; Nico, P. S.

2011-12-01

Lignin comprises a dominant proportion of carbon fluxes into the soil (representing up to 50% of plant litter and roots). Two lines of evidence suggest that manganese (Mn) acts as a strong controlling factor on the residence time of lignin in soil ecosystems. First, Mn content is highly correlated with litter decomposition in temperate and boreal forest soil ecosystems and, second, microbial agents of lignin degradation have been reported to rely on reactive Mn(III)-complexes to specifically oxidize lignin. However, few attempts have been made to isolate the mechanisms responsible for the apparent Mn-dependence of lignin decomposition in soils. Here we tested the hypothesis that Mn(III)-oxalate complexes may act as a perforating 'pretreatment' for structurally intact plant cell walls. We propose that these diffusible oxidizers are small enough to penetrate and react with non-porous ligno-cellulose in cell walls. This process was investigated by reacting single Zinnia elegans tracheary elements with Mn(III)-oxalate complexes in a continuous flow-through microreactor. The uniformity of cultured tracheary elements allowed us to examine Mn(III)-induced changes in cell wall chemistry and ultrastructure on the micro-scale using fluorescence and electron microscopy as well as synchrotron-based infrared and X-ray spectromicroscopy. Our results show that Mn(III)-complexes substantially oxidize specific lignin components of the cell wall, solubilize decomposition products, severely undermine the cell wall integrity, and cause cell lysis. We conclude that Mn(III)-complexes induce oxidative damage in plant cell walls that renders ligno-cellulose substrates more accessible for microbial lignin- and cellulose-decomposing enzymes. Implications of our results for the rate limiting impact of soil Mn speciation and availability on litter decomposition in forest soils will be discussed.

Viral recombination blurs taxonomic lines: examination of single-stranded DNA viruses in a wastewater treatment plant

Directory of Open Access Journals (Sweden)

Victoria M. Pearson

2016-10-01

Full Text Available Understanding the structure and dynamics of microbial communities, especially those of economic concern, is of paramount importance to maintaining healthy and efficient microbial communities at agricultural sites and large industrial cultures, including bioprocessors. Wastewater treatment plants are large bioprocessors which receive water from multiple sources, becoming reservoirs for the collection of many viral families that infect a broad range of hosts. To examine this complex collection of viruses, full-length genomes of circular ssDNA viruses were isolated from a wastewater treatment facility using a combination of sucrose-gradient size selection and rolling-circle amplification and sequenced on an Illumina MiSeq. Single-stranded DNA viruses are among the least understood groups of microbial pathogens due to genomic biases and culturing difficulties, particularly compared to the larger, more often studied dsDNA viruses. However, the group contains several notable well-studied examples, including agricultural pathogens which infect both livestock and crops (Circoviridae and Geminiviridae, and model organisms for genetics and evolution studies (Microviridae. Examination of the collected viral DNA provided evidence for 83 unique genotypic groupings, which were genetically dissimilar to known viral types and exhibited broad diversity within the community. Furthermore, although these genomes express similarities to known viral families, such as Circoviridae, Geminiviridae, and Microviridae, many are so divergent that they may represent new taxonomic groups. This study demonstrated the efficacy of the protocol for separating bacteria and large viruses from the sought after ssDNA viruses and the ability to use this protocol to obtain an in-depth analysis of the diversity within this group.

Status report - expert knowledge of operators in fuel reprocessing plants, enrichment plants and fuel fabrication plants

International Nuclear Information System (INIS)

Preuss, W.; Kramer, J.; Wildberg, D.

1987-01-01

The necessary qualifications of the responsible personnel and the knowledge required by personnel otherwise employed in nuclear plants are among the requirements for licensing laid down in paragraph 7 of the German Atomic Energy Act. The formal regulations for nuclear power plants are not directly applicable to plants in the fuel cycle because of the differences in the technical processes and the plant and work organisation. The aim of the project was therefore to establish a possible need for regulations for the nuclear plants with respect to the qualification of the personnel, and to determine a starting point for the definition of the required qualifications. An extensive investigation was carried out in the Federal Republic of Germany into: the formal requirements for training; the plant and personnel organisation structures; the tasks carried out by the responsible and otherwise employed personnel; and the state of training. For this purpose plant owners and managers were interviewed and the literature and plant specific documentation (e.g. plant rules) were reviewed. On the basis of literature research, foreign practices were determined and used to make comparative evaluations. The status report is divided into three separate parts for the reprocessing, the uranium enrichment, and the manufacture of the fuel elements. On the basis of the situation for reprocessing plants (particularly that of the WAK) and fuel element manufacturing plants, the development of a common (not uniform) regulation for all the examined plants in the fuel cycle was recommended. The report gives concrete suggestions for the content of the regulations. (orig.) [de

Full Text Available After five years of experience in interprofessional education (IPE in the Bachelor programs occupational therapy, midwifery, nursing, speech therapy, and physiotherapy at the University of Applied Sciences in Bochum (Germany, we have systematically evaluated and substantially revised our IPE concept in 2014/15. The structural and curricular embedding of IPE throughout the course of the five Bachelor programs requires the development and ongoing evolution of a binding concept for the interprofessional competence development. This concept needs to be based on a systematic reflection of current practice and sound scientific knowledge concerning interprofessional topics. Furthermore, it needs to address the promotion of competencies to act inter- and transprofessionally to enable a high quality of care (Wissenschaftsrat, 2012; Walkenhorst, 2012. Results of narrative literature reviews, structured internal discussions, interviews of experts and various internal and external evaluations have been incorporated into a new conceptual framework for IPE. It has been shown that a revision of the structure, the temporal sequences of modules and the framework to facilitate interprofessional practice are essential steps for continuous development of interprofessional education. In addition, barriers and challenges are identified and discussed. Overall, the process of development has been coordinated and accompanied continuously and successfully by an IPE committee involving different groups of representative members from the Department of Applied Health Sciences.

The impact of inverse photoemission spectroscopy measurements on regioregular poly(3-hexylthiophene) films

International Nuclear Information System (INIS)

Li, Zhi; Schlaf, Rudy; Sun, Siqi; Li, Xiao

2014-01-01

Inverse photoemission spectroscopy (IPES) enables the characterization of the density of states of unoccupied energy states above the Fermi level. However, due to the relatively high electron currents required to achieve useful signal to noise ratios, sample damage is a concern. Regioregular poly(3-hexylthiophene) (rr-P3HT) was used to systematically study the influence of electron radiation during IPES measurements on a prototypical conductive polymer. A series of IPES measurements exposing the samples to a range of electron fluxes was performed. An analysis of the electronic structure and the morphology showed that significant changes occurred in the investigated samples depending on the electron flux. X-ray diffraction results revealed that the root cause of the spectral changes is most likely related to crystallization of the film in an edge-on orientation. This was confirmed by Raman spectroscopy where both the C-C and C=C stretch modes shifted to lower frequencies after 5 IPES scans indicating a more ordered molecular structure. The observation of these stretch modes even after exposure to higher electron flux indicates that the main chemical structure of the P3HT molecules remains mostly intact during the IPES measurements. The absence of significant changes in C 1s and S 2p photoemission core level lines also confirmed this conclusion

Debating the use of work-based learning and interprofessional education in promoting collaborative practice in primary care: a discussion paper.

The context of primary care in the UK is changing rapidly, underpinned by continuing policy drivers to ensure person-centred safe and effective practice. Undergraduate and postgraduate programmes for healthcare practitioners are increasingly using interprofessional education (IPE) as one route to engender greater understanding of others' roles and contributions to health care, with the suggestion that IPE leads to better integration and teamwork, and thus stronger collaborative practice. Access to education and professional development for those working in primary care is difficult, and individuals need the focus of learning to be clearly relevant to their practice. To review and debate the evidence on the role of work-based learning and IPE in enhancing collaborative practice in primary care. Literature search and critique of key papers relevant to primary care practice. The three themes emerged of IPE, workbased learning (WBL) and collaborative practice. There is a growing body of literature to support the positive outcomes of IPE and the utilisation of WBL in developing practice. A range of practitioners in a variety of work settings have used WBL approaches in the implementation of innovations and the development of communities of practice. However, little evidence exists to support these approaches in primary care. The application of WBL across primary care teams can support a positive and collaborative learning culture, resulting in changes to professional practice.

Since 2012, the University of Wisconsin-Milwaukee (UWM) faculty from nursing and physical therapy (PT) have been working together towards a common goal: to meet the healthcare needs of vulnerable populations in Malawi and Milwaukee. Sharing valuable knowledge and understanding one another's professions have allowed us to develop interprofessional education (IPE) learning experiences for students to help identify how quality of life could be improved or enhanced for children and their families across two different geographic spaces, one in rural Malawi and the other in urban Milwaukee. IPE learning modules were implemented in UWM's community health-focused short-term study abroad programmes to Malawi. IPE learning modules were also piloted at one of UWM's nurse-managed community health centres, located in a low-income, African American community in the inner city of Milwaukee, Wisconsin. Based on survey data collected from 10 participating IPE students in Milwaukee, from nursing, occupational therapy, PT, and speech and language pathology, a pilot study yielded a statistically significant change in a positive direction for increased understanding of three interprofessional collaborative practice core competencies: values and ethics, roles and responsibilities, and teams and teamwork. In this article, we discuss the processes used to develop, implement, and evaluate IPE experiences for UWM students, which may enable other professionals to envision the various projects they can embark upon from an interprofessional perspective.

2018-05-01

Polyethylene (PE) pipe, particularly high-density polyethylene (HDPE) pipe, has been successfully utilized to transport cooling water for both non-safety- and safety-related applications in nuclear power plant (NPP). Though ASME Code Case N755, which is the first code case related to NPP HDPE pipe, requires a thorough nondestructive examination (NDE) of HDPE joints. However, no executable regulations presently exist because of the lack of a feasible NDE technique for HDPE pipe in NPP. This work presents a review of current developments in NDE technology for both HDPE pipe in NPP with a diameter of less than 400 mm and that of a larger size. For the former category, phased array ultrasonic technique is proven effective for inspecting typical defects in HDPE pipe, and is thus used in Chinese national standards GB/T 29460 and GB/T 29461. A defect-recognition technique is developed based on pattern recognition, and a safety assessment principle is summarized from the database of destructive testing. On the other hand, recent research and practical studies reveal that in current ultrasonic-inspection technology, the absence of effective ultrasonic inspection for large size was lack of consideration of the viscoelasticity effect of PE on acoustic wave propagation in current ultrasonic inspection technology. Furthermore, main technical problems were analyzed in the paper to achieve an effective ultrasonic test method in accordance to the safety and efficiency requirements of related regulations and standards. Finally, the development trend and challenges of NDE test technology for HDPE in NPP are discussed.

Plant growth-promoting rhizobacteria (PGPR) are increasingly appreciated for their contributions to primary productivity through promotion of growth and triggering of induced systemic resistance in plants. Here we focus on the beneficial effects of one particular species of PGPR (Pseudomonas fluorescens) on plants through induced plant defense. This model organism has provided much understanding of the underlying molecular mechanisms of PGPR-induced plant defense. However, this knowledge can only be appreciated at full value once we know to what extent these mechanisms also occur under more realistic, species-diverse conditions as are occurring in the plant rhizosphere. To provide the necessary ecological context, we review the literature to compare the effect of P. fluorescens on induced plant defense when it is present as a single species or in combination with other soil dwelling species. Specifically, we discuss combinations with other plant mutualists (bacterial or fungal), plant pathogens (bacterial or fungal), bacterivores (nematode or protozoa), and decomposers. Synergistic interactions between P. fluorescens and other plant mutualists are much more commonly reported than antagonistic interactions. Recent developments have enabled screenings of P. fluorescens genomes for defense traits and this could help with selection of strains with likely positive interactions on biocontrol. However, studies that examine the effects of multiple herbivores, pathogens, or herbivores and pathogens together on the effectiveness of PGPR to induce plant defenses are underrepresented and we are not aware of any study that has examined interactions between P. fluorescens and bacterivores or decomposers. As co-occurring soil organisms can enhance but also reduce the effectiveness of PGPR, a better understanding of the biotic factors modulating P. fluorescens-plant interactions will improve the effectiveness of introducing P. fluorescens to enhance plant production and defense.

Although interprofessional relationships are ubiquitous in clinical practice, undergraduate medical students have limited opportunities to develop these relationships in the clinical setting. A few student-faculty collaborative practice networks (SFCPNs) have been working to address this issue, but limited data exist examining the nature and extent of these practices. A systematic survey at a Harvard-affiliated SFCPN is utilised to evaluate the quantity and quality of interprofessional interactions, isolate improvements, and identify challenges in undergraduate interprofessional education (IPE). Our data corroborate previous findings in which interprofessional clinical learning was shown to have positive effects on student development and align with all four domains of Interprofessional Education Collaborative core competencies, including interprofessional ethics and values, roles and responsibilities, interprofessional communication, and teams and teamwork. These results highlight the unique opportunity and growing necessity of integrating IPE in SFCPNs to endorse the development of collaborative and professional competencies in clinical modalities of patient care.

Full Text Available To identify the antidiabetic plants of Iran, a systematic review of the published literature on the efficacy of Iranian medicinal plant for glucose control in patients with type 2 diabetes mellitus was conducted. We performed an electronic literature search of MEDLINE, Science Direct, Scopus, Proquest, Ebsco, Googlescholar, SID, Cochrane Library Database, from 1966 up to June 2010. The search terms were complementary and alternative medicine (CAM, diabetes mellitus, plant (herb, Iran, patient, glycemic control, clinical trial, RCT, natural or herbal medicine, hypoglycemic plants, and individual herb names from popular sources, or combination of these key words. Available Randomized Controlled Trials (RCT published in English or Persian language examined effects of an herb (limited to Iran on glycemic indexes in type 2 diabetic patients were included. Among all of the articles identified in the initial database search, 23 trials were RCT, examining herbs as potential therapy for type 2 diabetes mellitus. The key outcome for antidiabetic effect was changes in blood glucose or HbA1 c, as well as improves in insulin sensitivity or resistance. Available data suggest that several antidiabetic plants of Iran need further study. Among the RCT studies, the best evidence in glycemic control was found in Citrullus colocynthus, Ipomoea betatas, Silybum marianum and Trigonella foenum graecum.

Interprofessional education (IPE) is believed to prepare health professional graduates for successful collaborative practice. A range of instruments have been developed to measure the outcomes of IPE. An understanding of the psychometric properties of these instruments is important if they are to be used to measure the effectiveness of IPE. This review set out to identify instruments available to measure outcomes of IPE and collaborative practice in pre-qualification health professional students and to critically appraise the psychometric properties of validity, responsiveness and reliability against contemporary standards for instrument design. Instruments were selected from a pool of extant instruments and subjected to critical appraisal to determine whether they satisfied inclusion criteria. The qualitative and psychometric attributes of the included instruments were appraised using a checklist developed for this review. Nine instruments were critically appraised, including the widely adopted Readiness for Interprofessional Learning Scale (RIPLS) and the Interdisciplinary Education Perception Scale (IEPS). Validity evidence for instruments was predominantly based on test content and internal structure. Ceiling effects and lack of scale width contribute to the inability of some instruments to detect change in variables of interest. Limited reliability data were reported for two instruments. Scale development and scoring protocols were generally reported by instrument developers, but the inconsistent application of scoring protocols for some instruments was apparent. A number of instruments have been developed to measure outcomes of IPE in pre-qualification health professional students. Based on reported validity evidence and reliability data, the psychometric integrity of these instruments is limited. The theoretical test construction paradigm on which instruments have been developed may be contributing to the failure of some instruments to detect change in

New Opportunities for Remote Sensing Ionospheric Irregularities by Fitting Scintillation Spectra

Science.gov (United States)

Carrano, C. S.; Rino, C. L.; Groves, K. M.

2017-12-01

In a recent paper, we presented a phase screen theory for the spectrum of intensity scintillations when the refractive index irregularities follow a two-component power law [Carrano and Rino, DOI: 10.1002/2015RS005903]. More recently we have investigated the inverse problem, whereby phase screen parameters are inferred from scintillation time series. This is accomplished by fitting the spectrum of intensity fluctuations with a parametrized theoretical model using Maximum Likelihood (ML) methods. The Markov-Chain Monte-Carlo technique provides a-posteriori errors and confidence intervals. The Akaike Information Criterion (AIC) provides justification for the use of one- or two-component irregularity models. We refer to this fitting as Irregularity Parameter Estimation (IPE) since it provides a statistical description of the irregularities from the scintillations they produce. In this talk, we explore some new opportunities for remote sensing ionospheric irregularities afforded by IPE. Statistical characterization of irregularities and the plasma bubbles in which they are embedded provides insight into the development of the underlying instability. In a companion paper by Rino et al., IPE is used to interpret scintillation due to simulated EPB structure. IPE can be used to reconcile multi-frequency scintillation observations and to construct high fidelity scintillation simulation tools. In space-to-ground propagation scenarios, for which an estimate of the distance to the scattering region is available a-priori, IPE enables retrieval of zonal irregularity drift. In radio occultation scenarios, the distance to the irregularities is generally unknown but IPE enables retrieval of Fresnel frequency. A geometric model for the effective scan velocity maps Fresnel frequency to Fresnel scale, yielding the distance to the irregularities. We demonstrate this approach by geolocating irregularities observed by the CORISS instrument onboard the C/NOFS satellite.

For the past more than 50 years, the World Health Organisation has acknowledged through empirical findings that health workers that learn together work together effectively to provide the best care for their patients. This study aimed to: (1) describe the perceived extent of interprofessional education (IPE) experience among Filipino occupational therapists (OTs), physical therapists (PTs), and speech-language-pathologists (SLPs); (2) identify their attitudes towards interprofessional collaboration (IPC); and (3) compare their attitudes towards IPC according to: prior IPE experience, classification of IPE experience, profession, years of practice, and practice setting. Using a cross-sectional survey design, a two-part questionnaire was sent to Filipino OTs, PTs, and SLPs working in the Philippines via an online survey application. The first part of the survey contained eight items of demographic information and the second part contained the 14-item Attitudes Towards Health Care Teams Scale (ATHCTS). Findings revealed that among the Filipino OT, PT and SLP respondents (n = 189), 70.9% had prior experience on IPE. Moreover, the three most commonly used IPE teaching-learning strategies were case discussion (clinical setting), small group discussion, didactics, and case discussion (community setting), while the use of didactics and case discussion (community setting) yielded more agreeable attitudes towards IPC. Among the 14 items in the ATHCTS, 11 were rated with agreeability and three items with neutrality. For professional variables, only the practice setting variable yielded a statistically significant finding confirming those working in the academia to be more agreeable towards IPC compared to other settings. However, years of practice and professional background variables both yielded no statistically significant difference implying no association between years of practice and attitude towards IPC and a homogenous composition among respondents, respectively

Age-related macular degeneration (ARMD) is the leading cause for visual impairment and blindness in the elder population. Laser photocoagulation, photodynamic therapy and excision of neovascular membranes have met with limited success. Submacular transplantation of autologous iris pigment epithelial (IPE) cells has been proposed to replace the damaged retinal pigment epithelium following surgical removal of the membranes. We tested our hypothesis that the subretinal transplantation of genetically modified autologous IPE cells expressing biological therapeutics might be a promising strategy for the treatment of ARMD and other retinal disorders. Pigment epithelium-derived factor (PEDF) has strong antiangiogenic and neuroprotective activities in the eye. Subretinal transplantation of PEDF expressing IPE cells inhibited pathological choroidal neovascularization in rat models of laser-induced rupture of Bruch's membrane and of oxygen induced ischemic retinopathy. PEDF expressing IPE transplants also increased the survival and preserved rhodopsin expression of photoreceptor cells in the RCS rat, a model of retinal degeneration. These findings suggest a promising concept for the treatment of ARMD and other retinal disorders.

Risk-based equipment removal guide for on-line maintenance at PSE ampersand G

1995-01-01

On-line maintenance plays an important role in achieving safe and reliable power generation in a nuclear power plant. However, maintenance, if not properly planned and performed, may also be an important contributor to plant risk. Therefore, plant-specific procedures are needed for equipment removal from service to enhance the benefits of on-line maintenance and minimize the risks involved. The problem is to identify and implement the most effective on-line maintenance policy in the form of a proceduralized guide to assure plant safety under various operation and maintenance constraints. This paper presents a methodology to develop plant-specific on-line maintenance strategies and acceptance criteria using a multivariate safety approach based on risk assessment. Based on plant-specific data as modeled in the individual plant evaluation (IPE) and the updated probabilistic safety assessment (PSA), the risk-based methodology is currently being applied to the development of proceduralized equipment removal guides at Hope Creek and Salem units 1 and 2 of Public Service Electric and Gas Company (PSE ampersand G)

The unoccupied electronic state of delafossite-type PdCoO 2 has been studied using inverse-photoemission spectroscopy (IPES). The Fermi edge and the unoccupied density-of-state (DOS) at the Fermi level (E F ) are not observed in the IPES spectrum measured at the incidence electron energy (E K ) of 100 eV, which corresponds to the Cooper minimum of Pd 4d. The finite DOS at E F is observed in the IPES spectra measured at the lower E K , which the ionization cross section of Pd 4d increases. These findings indicate that the Pd 4d electron is closely related to the low electrical resistivity of PdCoO 2 . (author)

A meta-analysis of local adaptation in plants.

Directory of Open Access Journals (Sweden)

Roosa Leimu

Full Text Available Local adaptation is of fundamental importance in evolutionary, population, conservation, and global-change biology. The generality of local adaptation in plants and whether and how it is influenced by specific species, population and habitat characteristics have, however, not been quantitatively reviewed. Therefore, we examined published data on the outcomes of reciprocal transplant experiments using two approaches. We conducted a meta-analysis to compare the performance of local and foreign plants at all transplant sites. In addition, we analysed frequencies of pairs of plant origin to examine whether local plants perform better than foreign plants at both compared transplant sites. In both approaches, we also examined the effects of population size, and of the habitat and species characteristics that are predicted to affect local adaptation. We show that, overall, local plants performed significantly better than foreign plants at their site of origin: this was found to be the case in 71.0% of the studied sites. However, local plants performed better than foreign plants at both sites of a pair-wise comparison (strict definition of local adaption only in 45.3% of the 1032 compared population pairs. Furthermore, we found local adaptation much more common for large plant populations (>1000 flowering individuals than for small populations (<1000 flowering individuals for which local adaptation was very rare. The degree of local adaptation was independent of plant life history, spatial or temporal habitat heterogeneity, and geographic scale. Our results suggest that local adaptation is less common in plant populations than generally assumed. Moreover, our findings reinforce the fundamental importance of population size for evolutionary theory. The clear role of population size for the ability to evolve local adaptation raises considerable doubt on the ability of small plant populations to cope with changing environments.

Bulk Electrical Cable Non-Destructive Examination Methods for Nuclear Power Plant Cable Aging Management Programs

This Pacific Northwest National Laboratory milestone report describes progress to date on the investigation of nondestructive test methods focusing particularly on bulk electrical test methods that provide key indicators of cable aging and damage. The work includes a review of relevant literature as well as hands-on experimental verification of inspection capabilities. As nuclear power plants consider applying for second, or subsequent, license renewal to extend their operating period from 60 years to 80 years, it is important to understand how the materials installed in plant systems and components will age during that time and develop aging management programs to assure continued safe operation under normal and design basis events (DBE). Normal component and system tests typically confirm the cables can perform their normal operational function. The focus of the cable test program, however, is directed toward the more demanding challenge of assuring the cable function under accident or DBE. The industry has adopted 50% elongation at break (EAB) relative to the un-aged cable condition as the acceptability standard. All tests are benchmarked against the cable EAB test. EAB, however, is a destructive test so the test programs must apply an array of other nondestructive examination (NDE) tests to assure or infer the overall set of cable’s system integrity. Assessment of cable integrity is further complicated in many cases by vendor’s use of dissimilar material for jacket and insulation. Frequently the jacket will degrade more rapidly than the underlying insulation. Although this can serve as an early alert to cable damage, direct test of the cable insulation without violating the protective jacket becomes problematic. This report addresses the range of bulk electrical NDE cable tests that are or could be practically implemented in a field-test situation with a particular focus on frequency domain reflectometry (FDR). The FDR test method offers numerous advantages

Interprofessional collaboration (IPC) improves communication between healthcare workers and healthcare delivery. Interprofessional education (IPE) is essential in preparing healthcare students for cooperating with other healthcare disciplines in a real work setting. Although higher education settings have a responsibility to provide collaborative healthcare practice to students, IPE has not yet been prompted worldwide as a formal division in health professional education and in Israel IPE among health professions students is scarce. To examine the attitudes of health professions students towards IPC in correlation with their personal resilience and personality traits. A descriptive cross-sectional design was used. Participants were fourth year nursing, occupational therapy (OT), and physical therapy students studying in an academic undergraduate program at a School of Health Professions in a central university in Israel. Attitudes were assessed with a questionnaire consisting of the Interdisciplinary Education Perception Scale, the Connor-Davidson Resilience Scale, the Big Five Inventory of personality dimensions, and a question evaluating students' experience with the PBL (Problem-Based Learning) method. Questionnaires were completed by 184 health professions students. Nursing students' perception of actual cooperation with other professions and their perceived competency and autonomy in their profession were slightly lower than those of other students. Among nursing students, positive correlations were found between competency & autonomy and resilience (p<0.01) and between competency & autonomy and agreeableness (p<0.05). Positive correlations were also found between their perception of actual cooperation with other professions and: resilience (p<0.01), agreeableness (p<0.05), conscientiousness (p<0.05), and openness (p<0.05). Only OT students were familiar with and experienced in the PBL method. This experience with PBL was found correlated with more positive

Since the Nuclear Material Control Center (NMCC) was designed the safeguards inspection organization by Ministry of Education, Culture, Sports, Science and Technology (MEXT) in December 1999, the NMCC has been performing safeguards inspection for the Nuclear Facilities in Japan. The NMCC has carried out the safeguards inspections to LEU Fuel Fabrication Plants (FFPs) and the NMCC has improved the method of safeguards inspection as it has changed over to the integrated safeguards from the year of 2005. Concerning the Borrowing inspection between LEU FFPs, which is the precondition to change over to the integrated safeguards, it is needed to estimate the entire inventory in the facility within the limited time. Therefore, the NMCC has developed the system called IWES (In-process inventory Walk-through Examination System) to examine the inventory in process smoothly, quickly and correctly at borrowing inspection, check the entire inventory quantity and evaluate them. This report describes how IWES aiming at effective/efficient confirmation of in-process inventory has been developed and how it is applied to the borrowing inspection activities. (author)

Examination of some assumed severe reactor accidents at the Olkiluoto nuclear power plant

International Nuclear Information System (INIS)

Pekkarinen, E.; Rossi, J.

1989-02-01

Knowledge and analysis methods of severe accidents at nuclear power plants and of subsequent response of primary system and containment have been developed in last few years to the extent that realistic source tems of the specified accident sequences can be calculated for the Finnish nuclear power plants. The objective of this investigation was to calculate the source terms of off-site consequences brought about by some selected severe accident sequences initiated by the total loss of on-site and off-site AC power at the Olkiluoto nuclear power plant. The results describing the estimated off-site health risks are expressed as conditional assuming that the accident has taken place, because the probabilities of the occurence of the accident sequences considered have not been analysed in this study. The range and probabilities of occurence of health detriments are considered by calculating consequences in different weeather conditions and taking into account the annual frequency of each weather condition and statistical population distribution. The calculational results indicate that the reactor building provides and additional holdup and deposition of radioactive substance (except coble gases) released from the containment. Furthermore, the release fractions of the core inventory to the environment of volatile fission products such as iodine, cesium and tellurium remain under 0.03. No early health effects are predicted for the surrounding population in case the assumed short-tem countermeasures are performed effectively. Acute health effects are extremely improbable even without any active countermeasure. By reducing the long-term exposure from contaminated agricultural products, the collective dose from natural long-term background radiation, for instance in the sector of 30 degrees towards the southern Finland up to the distance of 300 kilometers, would be expected to increase with 2-20 percent depending on the release considered

The present study was undertaken to examine the effect of the application of fly ash (FA) into Garden soil (GS), with and without inoculation of plant growth promoting bacteria (PGPB), on the growth and metal uptake by Zea mays plants. Three FA tolerant PGPB strains, Pseudomonas sp. PS5, PS14, and Bacillus sp. BC29 were isolated from FA contaminated soils and assessed for their plant growth promoting features on the Z. mays plants. All three strains were also examined for their ability to solubilize phosphate and to produce Indole Acetic Acid (IAA), siderophores, and hydrogencynide acid (HCN) production. Although inoculation of all strains significantly enhanced the growth of plants at both the concentration of FA but maximum growth was observed in plants inoculated with BC29 and PS14 at low level (25%) of FA concentration. The experimental results explored the plant growth promoting features of selected strains which not only enhanced growth and biomass of plants but also protected them from toxicity of FA.

Novel weapons testing: are invasive plants more chemically defended than native plants?

Directory of Open Access Journals (Sweden)

Eric M Lind

2010-05-01

Full Text Available Exotic species have been hypothesized to successfully invade new habitats by virtue of possessing novel biochemistry that repels native enemies. Despite the pivotal long-term consequences of invasion for native food-webs, to date there are no experimental studies examining directly whether exotic plants are any more or less biochemically deterrent than native plants to native herbivores.In a direct test of this hypothesis using herbivore feeding assays with chemical extracts from 19 invasive plants and 21 co-occurring native plants, we show that invasive plant biochemistry is no more deterrent (on average to a native generalist herbivore than extracts from native plants. There was no relationship between extract deterrence and length of time since introduction, suggesting that time has not mitigated putative biochemical novelty. Moreover, the least deterrent plant extracts were from the most abundant species in the field, a pattern that held for both native and exotic plants. Analysis of chemical deterrence in context with morphological defenses and growth-related traits showed that native and exotic plants had similar trade-offs among traits.Overall, our results suggest that particular invasive species may possess deterrent secondary chemistry, but it does not appear to be a general pattern resulting from evolutionary mismatches between exotic plants and native herbivores. Thus, fundamentally similar processes may promote the ecological success of both native and exotic species.

Patient care and patient safety can be compromised by the lack of interprofessional collaboration and communication between healthcare providers. Interprofessional education (IPE) should therefore start during medical training and not be postponed until after graduation. This case study explored the current situation in the Dutch context and interviewed experts within medical education and with pioneers of successful best practices to learn more about their experiences with IPE. Data analysis started while new data were still collected, resulting in an iterative, constant comparative process. Using a strengths, weaknesses, opportunities, and threats (SWOT) analysis framework, we identified barriers and facilitators such as lack of a collective professional language, insufficient time or budget, stakeholders' resistance, and hierarchy. Opportunities and strengths identified were developing a collective vision, more attention for patient safety, and commitment of teachers. The facilitators and barriers relate to the organisational level of IPE and the educational content and practice. In particular, communication, cohesiveness, and support are influenced by these facilitators. An adequate identification of the SWOT elements in the current situation could prove beneficial for a successful implementation of IPE within the healthcare educational system.

Plant adaptation to temperature and photoperiod

Directory of Open Access Journals (Sweden)

2008-12-01

Full Text Available Plants respond to environmental conditions both by adaptation and by acclimation. The ability of the plants to grow, reproduce and survive under changing climatic conditions depends on the efficiency of adaptation and acclimation. The adaptation of developmental processes in plants to temperature and photoperiod is briefly reviewed. In annual plants this adaptation is related to growth capacity and to the timing of reproduction. In perennial plants growing under northern conditions, adaptation of the annual growth cycle to the local climatic cycle is of primary importance. Examples of the role of photothermal conditions in regulation of these phenological processes are given and discussed. The genetic and physiological bases for climatic adaptation in plants are briefly examined.;

PRA -- Now that operators have it, what do they do with it?

International Nuclear Information System (INIS)

Rasmussen, M.A.; Kolo, R.J.

1996-01-01

Many utilities have had Probabilistic Risk Assessment (PRA) projects underway for several years in order to satisfy the NRC Generic Letter 88-20 requirement for an Individual Plant Examination, or IPE. Typically the studies have reached the conclusion that there are significant differences in the contribution of different plant components to preventing core damage should a major plant transient occur. How nuclear plant operators can use this knowledge to DECREASE the overall risk of performing the routine tasks of testing and maintenance is not an easy task. 10CFR50.65; ''The Maintenance Rule,'' requires that any plant maintenance performed with the unit on line be evaluated for risk. Byron Station will satisfy the 10CFR50.65 requirement by using PRA methodology to evaluate testing and maintenance activities performed with the unit at power. The challenge is to effectively use the results of PRA studies to aid in plant operations without having to make on shift plant operations personnel experts in PRA. At Byron, PRA is used to help build the weekly work schedules. Operations personnel tasked with reviewing the work schedule are the departmental experts on the use of the PRA results. The on shift SRO's role in implementing the program is to accurately execute and monitor the work week schedule as written, and to react to unforeseen equipment failures with an appropriate level of response. The response to such emergent work items is also predefined. Handling emergent work in a prescribed manner minimizes the overall risk to the unit and also eliminates the need to have PRA expertise available to make emergent work risk evaluations. Thus the on shift operators' required knowledge of PRA methods and intricacies is minimized. PRA is just another of the many tools used by the shift operator to run the plant in a safe, conservative manner

Phytochrome, plant growth and flowering

Attempts to use artificially lit cabinets to grow plants identical to those growing in sunlight have provided compelling evidence of the importance of light quality for plant growth. Changing the balance of red (R) to far-red (FR) radiation, but with a fixed photosynthetic input can shift the phytochrome photoequilibrium in a plant and generate large differences in plant growth. With FR enrichment the plants elongate, and may produce more leaf area and dry matter. Similar morphogenic responses are also obtained when light quality is altered only briefly (15-30 min) at the end-of-the-day. Conversely, for plants grown in natural conditions the response of plant form to selective spectral filtering has again shown that red and far-red wavebands are important as found by Kasperbauer and coworkers. Also, where photosynthetic photon flux densities (PPFD) of sunlight have been held constant, the removal of far-red alone alters plant growth. With FR depletion plants grown in sunlight are small, more branched and darker green. Here we examine the implications for plant growth and flowering when the far-red composition of incident radiation in plant growth chambers is manipulated.

Intensity attenuation for active crustal regions

Allen, Trevor I.; Wald, David J.; Worden, C. Bruce

2012-07-01

We develop globally applicable macroseismic intensity prediction equations (IPEs) for earthquakes of moment magnitude M W 5.0-7.9 and intensities of degree II and greater for distances less than 300 km for active crustal regions. The IPEs are developed for two distance metrics: closest distance to rupture ( R rup) and hypocentral distance ( R hyp). The key objective for developing the model based on hypocentral distance—in addition to more rigorous and standard measure R rup—is to provide an IPE which can be used in near real-time earthquake response systems for earthquakes anywhere in the world, where information regarding the rupture dimensions of a fault may not be known in the immediate aftermath of the event. We observe that our models, particularly the model for the R rup distance metric, generally have low median residuals with magnitude and distance. In particular, we address whether the direct use of IPEs leads to a reduction in overall uncertainties when compared with methods which use a combination of ground-motion prediction equations and ground motion to intensity conversion equations. Finally, using topographic gradient as a proxy and median model predictions, we derive intensity-based site amplification factors. These factors lead to a small reduction of residuals at shallow gradients at strong shaking levels. However, the overall effect on total median residuals is relatively small. This is in part due to the observation that the median site condition for intensity observations used to develop these IPEs is approximately near the National Earthquake Hazard Reduction Program CD site-class boundary.

Interprofessional Education: Opportunities and Challenges for Psychology.

This manuscript is an outgrowth of an invited panel presentation at the national Association for Psychologists in Academic Health Centers Conference in 2017 on Interprofessional Education (IPE). IPE is a structured and transformative educational strategy designed to provide active learning experiences where trainees from diverse healthcare professions gain shared content knowledge plus collaboration skills as they learn about, from, and with each other. Collaboration skills include understanding professional role distinctions and overlap, effective team-based communication, shared values/ethics and respect for each other's expertise, and teamwork dynamics. It is increasingly important to expand training beyond the intraprofessional activities in which psychology trainees engage to prepare them to participate in interprofessional collaborative care. As healthcare systems move to team-based collaborative practice and value-based reimbursement models, the profession of psychology needs leaders at every academic health center to facilitate the design and/or implementation of IPE activities. The panel of psychologists presented roles that psychologists play in IPE institutional program design and implementation, graduate training programs, and the perspectives of an early career psychologist and psychology trainee. Opportunities and challenges are highlighted, culminating in a call to action. Psychologists must embrace their identity as health professionals and engage their learners in IPE so that the emerging cognitive schemata of healthcare that is developed includes the profession of psychology. Otherwise, healthcare teams and health professionals will not understand the value, roles, or potential contributions of psychologists in enhancing patient care outcomes, ultimately jeopardizing psychologists' referrals, involvement in healthcare delivery, and career opportunities.

Interprofessional education (IPE) has received little attention in veterinary education even though members of the veterinary and nursing professions work closely together. The present study investigates veterinary and veterinary nursing students' and practitioners' experiences with interprofessional issues and the potential benefits of IPE. Based on stakeholder consultations, two teaching interventions were modified or developed for use with veterinary and veterinary nursing students: Talking Walls, which aimed to increase individuals' understanding of each other's roles, and an Emergency-Case Role-Play Scenario, which aimed to improve teamwork. These interventions were piloted with volunteer veterinary and veterinary nursing students who were recruited through convenience sampling. A questionnaire (the Readiness for Interprofessional Learning Scale [RIPLS]) was modified for use in veterinary education and used to investigate changes in attitudes toward IPE over time (pre-intervention, immediately post-intervention, and four to five months afterward). The results showed an immediate and significant positive change in attitude after the intervention, highlighting the students' willingness to learn collaboratively, their ability to recognize the benefits of IPE, a decreased sense of professional isolation, and reduced hierarchical views. Although nearly half of the students felt concerned about learning with students from another profession before the intervention, the majority (97%) enjoyed learning together. However, the positive change in attitude was not evident four to five months after the intervention, though attitudes remained above pre-intervention levels. The results of the pilot study were encouraging and emphasize the relevance and importance of veterinary IPE as well as the need for further investigation to explore methods of sustaining a change in attitude over time.

Two novel zoledronic acid (ZL) derivatives, 1-hydroxy-4-(1H-imidazol-1-yl)butane-1,1-diyldiphosphonic acid (IBDP) and 1-hydroxy-5-(1H-imidazol-1-yl)pentane-1,1-diyldiphosphonic acid (IPeDP), were prepared and labeled with the radionuclide technetium-99m in a high labeling yield. In vitro stabilities of these radiolabeled complexes were measured by the radio-HPLC analysis as a function of time, which showed excellent stability with the radiochemical purity of over 95% at 6 h post preparation. Their in vivo biological performances were evaluated and compared with those of {sup 99m}Tc-ZL and {sup 99m}Tc-MDP (methylenediphosphonic acid). The biodistribution in mice and scintigraphic images of the rabbit showed that the tracer agent {sup 99m}Tc-IPeDP had highly selective uptake in the skeletal system and rapid clearance from the blood and soft tissues and an excellent scintigraphic image can be obtained in a shorter time post injection with clear visualization of the skeleton and low soft tissue activity. These preclinical studies suggest that {sup 99m}Tc-IPeDP would be a novel superior bone scintigraphic agent. - Highlights: Black-Right-Pointing-Pointer Two novel diphosphonic acids were labeled with the {sup 99m}Tc in high labeling yield. Black-Right-Pointing-Pointer {sup 99m}Tc-IPeDP had high uptake in skeletal system and rapid clearance from blood. Black-Right-Pointing-Pointer {sup 99m}Tc-IPeDP reveals attractive biological features as superior bone scanning agent.

The chemical constituents of intact plant material, including living plants, are examined by a simple spray method that provides real-time information on sugars, amino acids, fatty acids, lipids, and alkaloids. The experiment is applicable to various plant parts and is demonstrated for a wide variety of species. An electrical potential is applied to the plant and its natural sap, or an applied solvent generates an electrospray that carries endogenous chemicals into an adjacent benchtop or miniature mass spectrometer. The sharp tip needed to create a high electric field can be either natural (e.g., bean sprout) or a small nick can be cut in a leaf, fruit, bark, etc. Stress-induced changes in glucosinolates can be followed on the minute time scale in several plants, including potted vegetables. Differences in spatial distributions and the possibility of studying plant metabolism are demonstrated. © 2011 American Chemical Society

The French safety authorities have undertaken a systematic evaluation of the safety of old nuclear power plants. Apart from a complete revision of safety documents (safety analysis report, general operating rules, incident and accident procedures, internal emergency plan, quality organisation manual), this examination consisted of analysing the operating experience of systems frequently challenged and a systematic examination of the safety-related systems. This paper is based on an exercise at the Ardennes Nuclear Power Plant which has been in operation for 15 years. This paper also summarizes the main surveys and modifications relating to this power plant. (orig.)

This study was carried out to compare the hematological effects of 2-methoxyethanol (ME), 2-ethoxyethanol (EE), 2-isopropoxyethanol (IPE), and 2-butoxyethanol (BE) in short-term studies in rats. Male rats were subcutaneously treated with ME or EE at a dosage of 0, 1.25, 2.5 and 5.0 mM/kg in saline, 5 days per week, for 4 weeks. Other rats were exposed to IPE or BE at doses of 0, 0.25, 0.5, 0.75 and 1.25 mM/kg in the same manner. Administration of each chemical, except of ME, resulted in a time- and dose-dependent swelling of erythrocytes as evidenced by an increase in mean corpuscular volume (MCV). Subsequently, red blood cells (RBC), packed cell volumes (PCV), hemoglobin concentration (HGB), and mean cell hemoglobin concentration (MCHC) decreased. Furthermore, an increase in mean cell hemoglobin (MCH) and reticulocyte counts was observed. The onset of hemolysis induced by EE, IPE or BE was faster than after ME administration. While in rats exposed to ME hematological changes were strongly pronounced and progressively increased with exposure time beginning from the day 11, those in animals treated with EE were rather persisted at low constant level for all exposure period. In contrast, the rats exposed to IPE and BE demonstrated the dramatic hematological changes more pronounced in case of BE than IPE at the beginning of exposure (on day 4). Despite of exposure duration, these changes were regressed, although the decrease in RBC and MCHC and the increase in MCV and MCH in rats treated with highest doses of both compound (0.5, 0.75, and 1.25 mM/kg) were more persistent, probably due to selective hemolysis of the aged erythrocytes. In addition, significant leukopenia due to reduction of lymphocytes in rats exposed to ME was observed. In summary, this study demonstrated no tolerance to ME- and EE-induced intravascular hemolysis developed under these experimental conditions. On the contrary, tolerance to IPE- and BE-induced hemolysis in rats exposed to these compounds

Reliable performance of nuclear fuels and critical core components has a large bearing on the economics of nuclear power and radiation safety of plant operating personnel. In view of this, Post Irradiation Examination (PIE) is periodically carried out on fuels and components to generate feedback information which is used by the designers, fabricators and the reactor operators to bring about changes for improved performance of the fuel and components. Examination of the fuel bundles has to be carried out inside hot cells due to their high radioactivity

Process Experimental Pilot Plant

The Process Experimental Pilot Plant (PREPP) at the Idaho National Engineering Laboratory (INEL) was built to convert transuranic contaminated solid waste into a form acceptable for disposal at the Waste Isolation Pilot Plant (WIPP), located near Carlsbad, New Mexico. There are about 2.0 million cubic ft of transuranic waste stored at the Transuranic Storage Area of the INEL's Radioactive Waste Management Complex (RWMC). The Stored Waste Examination Pilot Plant (SWEPP) located at the RWMC will examine this stored transuranic waste to determine if the waste is acceptable for direct shipment to and storage at WIPP, or if it requires shipment to PREPP for processing before shipment to WIPP. The PREPP process shreds the waste, incinerates the shredded waste, and cements (grouts) the shredded incinerated waste in new 55-gal drums. Unshreddable items are repackaged and returned to SWEPP. The process off-gas is cleaned prior to its discharge to the atmosphere, and complies with the effluent standards of the State of Idaho, EPA, and DOE. Waste liquid generated is used in the grouting operation

Countermeasures to earthquakes in nuclear plants

The contribution of atomic energy to mankind is unmeasured, but the danger of radioactivity is a special thing. Therefore in the design of nuclear power plants, the safety has been regarded as important, and in Japan where earthquakes occur frequently, the countermeasures to earthquakes have been incorporated in the examination of safety naturally. The radioactive substances handled in nuclear power stations and spent fuel reprocessing plants are briefly explained. The occurrence of earthquakes cannot be predicted effectively, and the disaster due to earthquakes is apt to be remarkably large. In nuclear plants, the prevention of damage in the facilities and the maintenance of the functions are required at the time of earthquakes. Regarding the location of nuclear plants, the history of earthquakes, the possible magnitude of earthquakes, the properties of ground and the position of nuclear plants should be examined. After the place of installation has been decided, the earthquake used for design is selected, evaluating live faults and determining the standard earthquakes. As the fundamentals of aseismatic design, the classification according to importance, the earthquakes for design corresponding to the classes of importance, the combination of loads and allowable stress are explained.

Hannon, J.N.

1988-01-01

The human element in the operation of commercial nuclear power plants is of utmost importance. Not only must the operators be technically competent in the execution of numerous complicated tasks, they must be capable of working together as a team to diagnose dynamic plant conditions to ensure that their plants are operated safely. The significance of human interaction skills and crew communications has been demonstrated most vividly in TMI and Chernobyl. It follows that the NRC must retain its high standards for licensing operators. This paper discusses activities and initiatives being employed by the NRC to enhance the reliability of its licensing examinations, and to build a highly qualified examiner work force

Influence of fly dust from coking plants on some biological processes of plants

Masek, V

1972-03-01

The influence of three typical samples of fly dust from a coking plant on enzymatic reactions, photosynthesis, chlorophyll concentration in leaves of bean plants was studied. The hydrolysis of starch with amylases and of the albumen with pepsin at 37 C and the inversion of sacharosis by invertase in a buffered environment were also examined. None of the three dust samples had a significant effect on enzymatic reactions. Applying the dust samples to the leaves of young bean plants reduced the intensity of photosynthesis and chlorophyll concentration. In aqueous extracts, the dust samples liberated only small quantities of nutrients, plants which were grown in a dust suspension showed no increase of dry substance and growth rate. A stimulating effect of the dust samples on root growth was determined. Mixing the dust samples with the soil influenced the accessibility of water to plants. 17 references, 6 figures, 9 tables.

This study aimed to develop, implement and evaluate an online interprofessional education (IPE) dementia case study for health science students. The IPE initiative aimed to develop collaborative interprofessional capabilities and client-centred mindsets that underpin high-quality dementia care. A mixed methods research design was used to assess students' values, attitudes and learning outcomes using an interprofessional socialization and valuing scale (ISVS) completed pre and post the online case study and via thematic analysis of free text responses. Students' ISVS scores improved significantly following online participation, and the qualitative results support a shift towards interprofessional collaboration and client-centred care. This online IPE case study was successful in developing the collaborative mindsets and interprofessional capabilities required by a future workforce to meet the complex, client-centred needs of people living with dementia. © 2013 ACOTA.

2014-01-01

Summary In the second of three lessons spanning the topic of Plant Nutrition, we examine how macronutrients affect plant growth. Specifically, we look at (1) the availability of nutrients in the soil along with the effects of soil microbes and physical properties on their availability; (2) nutrient uptake from the external environment, across plasma membranes and into plant cells; (3) in some cases, the assimilation of the nutrient into organic molecules; (4) the distribution and redistribution of nutrients throughout the plant; and (5) regulation of these processes. In parallel, we examine the genetic basis of a plant's nutrient use efficiency (NUE) and evaluate strategies by which to replenish nutrients that growing plants extract from soil.

Effect of decision making on ultrasonic examination performance

International Nuclear Information System (INIS)

Harris, D.H.

1992-05-01

A decision aid was developed to overcome examiner limitations in information processing and decision making during ultrasonic examinations. The aid provided a means of noting signal characteristics as they were observed during the examination, and of presenting them simultaneously for decision making. The aid also served as a way of providing detailed feedback on examination performance during training. The aid was incorporated into worksheets used for the conduct of practice examinations during ultrasonic examination training. To support the introduction and use of the decision aid, one hour of supplementary training was inserted in an existing 64-hour training course on ultrasonic detection of defects. This study represented a modest step in improving the performance of ultrasonic examinations in nuclear power plants. Findings indicated that aided decision making supported by limited training can significantly improve ultrasonic detection performance

Plant foods and plant-based diets: protective against childhood obesity?

Science.gov (United States)

Newby, P K

2009-05-01

The objective of this article is to review the epidemiologic literature examining the role of plant foods and plant-based diets in the prevention of childhood obesity. Available data suggest a protective effect of ready-to-eat cereal on risk of obesity, although prospective studies are still needed. Studies on fruit and vegetables; grains other than cereal; high-protein foods, including beans, legumes, and soy; fiber; and plant-based dietary patterns are inconsistent or generally null. The evidence base is limited, and most studies are fraught with methodologic limitations, including cross-sectional design, inadequate adjustment for potential confounders, and lack of consideration of reporting errors, stage of growth, and genetic influences. Well-designed prospective studies are needed. The lack of evidence showing an association between plant-based diets and childhood obesity does not mean that such diets should not be encouraged. Plant foods are highlighted in the Dietary Guidelines for Americans, and children do not meet the current recommendations for most plant foods. Although the advice to consume a plant-based, low-energy-dense diet is sound, ethical questions arise concerning the relatively high price of these diets in the United States and the way in which such diets are perceived in other parts of the world. Reducing the burden of childhood obesity, eliminating health disparities, and preventing the further spread of the disease around the globe will require not only policy interventions to ensure that plant foods are affordable and accessible to children of all income levels but also awareness of sociocultural norms that affect consumption.

Full Text Available Nitrogen and protein contents in higher aquatic plants deriving from a natural habitat were determined. The following plants were examined: Spirodela polyrrhiza (L. Schleid., Elodea canadensis Rich., Riccia fluitans L. Total nitrogen and nitrogen of respective fractions were determined by the Kjeldahl method. Nitrogen compounds were fractionated according to Thimann et al. Protein was extracted after Fletcher and Osborne and fractionated after Osborne. It was found, that total protein content in the plants under examination constitutes 18 to 25%o of dry matter. Albumins and glutelins are the most abundant protein fractions.

Effects of hydrogen fluoride on plants

Energy Technology Data Exchange (ETDEWEB)

Yamazoe, F

1970-07-15

Symptoms of fluorosis in plants are chlorotic markings around the tip or edges of young leaves. Examples of damage to plants and livestock by fluorides are listed, including the retarded growth of silkworms fed on mulberry leaves polluted by more than 30 ppm fluorides. Plants can be classified into six groups according to their resistance to hydrogen fluoride. Threshold values of the fluoride concentration range from 5-10 ppb for the plants. Gladiolus is normally employed as a plant indicator for hydrogen fluoride and silkworms as indicator insects. The relationship between plant damage by fluorides and exposure time, density, soil, fertilizer, meteorology and location are examined. Several preventive measures are listed, including the spraying of water or lime on plant leaves. It is concluded that the establishment of an environmental standard is difficult because of the extremely high sensitivity of the plants to the gas. 8 references.

Initial examination of the effects of overtime and shift scheduling on nuclear power plant safety performance

International Nuclear Information System (INIS)

Baker, K.; Olson, J.; Montgomery, J.

1990-01-01

The research reported here uses currently available data to begin to document overtime and shift scheduling practices in the nuclear industry and assess their safety consequences. Overtime and the 12-hour shift schedule have been found to affect employee fatigue and human error in other industries but neither of these practices have been systematically researched within the nuclear industry. Overtime has long been a standard practice in the nuclear industry and, recently, several licensees have adopted a 12-hour shift schedule for control room operations crews. Although 12-hour shifts have certain benefits for the employer and employee alike (e.g., can require fewer total employees and provide longer periods of time-off) there is some concern that the 12-hour shift may produce greater employee fatigue. Moreover, the 12-hour shift may exacerbate the negative effect of overtime. The potential effect of human error in the nuclear industry for the health and safety of both nuclear power plant workers and the general public requires that these practices be assessed. Data on overtime practices was obtained from the International Brotherhood of Electrical Workers (IBEW) for plants covered by the bargaining unit - approximately 63% of the total number of operating plants. Information on operator shift schedule was collected from all operating plants in 1987 by the NRC. The research produced fairly strong evidence that greater amounts of overtime worked by operators is associated with a greater number of operational problems

In this study, two different electric power plants for the production of about 1000 MWe which were based on a CO 2 laser driver and on a heavy ion driver have been developed and analyzed. The purposes of this study were: (1) to examine in a self consistent way the technological and institutional problems that need to be confronted and solved in order to produce commercially competitive electricity in the 2020 time frame from an inertial fusion reactor, and (2) to compare, on a common basis, the consequences of using two different drivers to initiate the DT fuel pellet explosions. Analytic descriptions of size/performance/cost relationships for each of the subsystems comprising the power plant have been combined into an overall computer code which models the entire plant. This overall model has been used to conduct trade studies which examine the consequences of varying critical design values around the reference point

Successful engagement of cascade control systems used to control complex nuclear plant often present control engineers with difficulties when trying to obtain early automatic operation of these systems. These difficulties often arise because prior to the start of live plant operation, control equipment performance can only be assessed using open loop techniques. By simulating simple models of plant on a computer and linking it to the site control equipment, the performance of the system can be examined and optimised prior to live plant operation. This significantly reduces the plant down time required to correct control equipment performance faults during live plant operation

Remote visual examination is one of the most important methods for non- destructive in-service inspections of primary components in nuclear power plants. It features two main advantages: the short examination duration and the fast interpretation of results. AREVA offers operators of nuclear power plants the ''SUSI 420 HD'' SUbmarine System for Inspections to perform ENIQ-qualified visual examinations during outages without working on the critical path and causing any delay in the time schedule. The system is a remotely operated manipulator equipped with a high definition camera. With a weight of only 25 kg, there is no need for a crane to put the submarine into water. More-over, nor the use of the refueling machine neither the auxiliary bridge is required. In this way the visual examination can be performed in parallel to other activities which are on the critical path. The article takes a closer look at the essential parameters: illumination, examination distance, viewing angle, scanning speed, positioning accuracy and sizing of indications. It describes how the system can fulfill these parameters through some adaptations.

The provision of deuterium, tritium, lithium and beryllium fuel materials for fusion power plants is examined in this document. Possible fusion reactions are discussed for use in first generation power plants. Requirements for fuel materials are considered. A range of expected annual consumption is given for each of the materials for a 1000 megawatts electric (MWe) fusion power plant. Inventory requirements are also given. Requirements for an assumed fusion power plant electrical generating capacity of 10 6 MWe (roughly twice present U.S. generating capacity) are also given. The supply industries are then examined for deuterium, lithium, and beryllium. Methods are discussed for producing the only tritium expected to be purchased by a commercial fusion industry--an initial inventory for the first plant. Present production levels and methods are described for deuterium, lithium and beryllium. The environmental impact associated with production of these materials is then discussed. The toxicity of beryllium is described, and methods are indicated to keep worker exposure to beryllium as low as achievable

2015-12-01

Synthesis of silver nanoparticles by plants and plant extracts (green synthesis) has been developed into an important innovative biotechnology, especially in the application of such particles in the control of pathogenic bacteria. This is a safer technology, biologically and environmentally, than synthesis of silver nanoparticles by chemical or physical methods. Plants are preferable to microbes as agents for the synthesis of silver nanoparticles because plants do not need to be maintained in cell culture. The antibacterial activity of bionanoparticles has been extensively explored during the past decade. This review examines studies published in the last decade that deal with the synthesis of silver nanoparticles in plants and their antibacterial activity.

1987-01-01

Since 1954, defense-generated transuranic (TRU) waste has been received at the Radioactive Waste Management Complex (RWMC) at the Idaho National Engineering Laboratory (INEL). A major objective of the Department of Energy (DOE) Nuclear Waste Management Programs is the proper management of the defense-generated TRU waste. The Stored Waste Examination Pilot Plant (SWEPP) is providing nondestructive examination and assay of retrievably stored contact handled TRU waste in order to certify it to the Waste Isolation Pilot Plant Waste Acceptance Crtieria (WIPP-WAC). SWEPP's capabilities for certifying contact handled waste containers include weighing, real-time radiographic examination, fissile material assay examination, container integrity examination, radiological surveys and labeling of waste containers. These processes involve not only instrument accuracy but also a wide range of technician interpretation from moderate on the assay to 100% on the radiograph. This, therefore, requires a variety of quality assurance techniques to ensure that the examinations and certifications are being performed correctly. The purpose of this paper is to discuss the methods utilized by SWEPP for checking on the examination process and to ensure that waste certifications are being properly performed. Included is the application of the quality assurance techniques to each examination system, the management of the data generated by the examination, and the verifications to ensure accurate certification. 1 ref

Use of nondestructive evaluation methods to improve power plant availability

International Nuclear Information System (INIS)

Weber, R.M.

1985-01-01

On an ever-increasing basis, utilities are relying on nondestructive evaluation (NDE) as a management and planning tool. In addition to the conventional ASME Code and Technical Specification-required examinations, progressive utilities are utilizing NDE sampling programs to monitor existing conditions and search for potential situations affecting plant safety and reliability. Improved NDE detection and sizing procedures give management personnel the accurate information needed to make the ''go/no go'' decisions on repair programs which can significantly affect plant availability. As the burden of regulatory-imposed inspection requirements increases, plant personnel are increasingly cognizant that NDE is a significant factor in their plant's outage schedule. Whether an outage is scheduled or forced, NDE becomes part of each plant's program to assure the safety and reliability of its critical components. Knowledge and planning of NDE application is important because of the time expended in examination performance and subsequent data evaluation. Managers who are knowledgeable in NDE application can effectively improve plant availability by scheduling NDE as an integral part of their maintenance programs. Examination results can then be used in making decisions directly affecting availability

Knowledge and abilities catalog for nuclear power plant operators: boiling water reactors

1986-09-01

The Knowledge and Abilities Catalog for Nuclear Power Plant Operators: Boiling-Water Reactors (BWR) (NUREG-1123) provides the basis for the development of content-valid licensing examinations for reactor operators (ROs) and senior reactor operators (SROs). The examinations developed using the BWR Catalog and Examiners' Handbook for Developing Operator Licensing Examinations (NUREG-1121) will cover those topics listed under Title 10, Code of Federal Regulations, Part 55. The BWR Catalog contains approximately 7000 knowledge and ability (K/A) statements for ROs and SROs at boiling water reactors. Each K/A statement has been rated for its importance to the safe operation of the plant in a manner ensuring personnel and public health and safety. The BWR K/A Catalog is organized into five major sections: Plant-wide Generic Knowledge and Ability Statements, Plant Systems grouped by Safety Function, Emergency and Abnormal Plant Evolutions, Components, and Theory. The BWR Catalog represents a modification of the form and content of the K/A Catalog for Nuclear Power Plant Operators: Pressurized Water Reactors (NUREG-1122). First, categories of knowledge and ability statements have been redefined. Second, the scope of the definition of emergency and abnormal plant evolutions has been revised in line with a symptom-based approach. Third, K/As related to the operational applications of theory have been incorporated into the delineations for both plant systems and emergency and abnormal plant evolutions, while K/As pertaining to theory fundamental to plant operation have been delineated in a separate theory section. Finally, the components section has been revised

Perspectives of nuclear power plants

In several countries the construction of nuclear power plants has been stopped, and in some counties several plants have been decommissioned or are planned to. Therefore, the question arises: have nuclear power plants any future? According to the author, the question should be reformulated: can mankind survive without nuclear power? To examine this challenge, the global power demand and its trends are analyzed. According to the results, traditional energy sources cannot be adequate to supply power. Therefore, a reconsideration of nuclear power should be imminent. The economic, environmental attractions are discussed as opposite to the lack of social support. (R.P.)

Interprofessional Education Perceptions of Dental Assisting and Radiologic Technology Students Following a Live Patient Experience.

Reddington, Amanda R; Egli, Amy J; Schmuck, Heather M

2018-05-01

Health professions students are often unaware of other health care providers' roles or professional expertise due to most education taking place within their single profession. This pattern may be even more prevalent for baccalaureate and associate degree programs since most interprofessional education (IPE) occurs in predoctoral programs and, when IPE is incorporated into allied health professions education, it often utilizes simulation instead of live patient experiences. The aim of this study was to determine if radiologic technology and dental assisting students' perceptions changed regarding interprofessional practice and teamwork after an IPE activity with actual patients. The participants were students in the University of Southern Indiana (USI) radiologic technology and dental assisting programs. This mixed-methods pilot study conducted in 2017 collected quantitative and qualitative data from pre and post surveys, the researchers' observations of student interactions during live patient assessment and acquisition of panoramic images, and large-group discussion. Twenty-five of the 26 students who participated in the IPE program completed both pre and post surveys, for a 96% response rate. The results showed significant differences in the participants' perceptions from the pre to post surveys on a wide variety of survey items. Most notable were the positive changes in perceptions related to trust in judgment of others within their profession (p=0.001), relationships with other professions (p=0.002), and thinking highly of other professions (p=0.002). Overall, this study found that incorporating the IPE activity with a live patient into these radiologic technology and dental assisting programs improved the students' perceptions of other allied health professionals. Future research should include more participants to increase sample size and add quantitative data collection.

Lung structure-respiratory function relationships in experimentally-induced bronchiolitis, bronchopneumonia and interstitial pneumonia in rats

Energy Technology Data Exchange (ETDEWEB)

Mauderly, J L; Madron, E de; Harkema, J R

1988-12-01

Histopathology and respiratory function of rats with three different types and distributions of lower lung inflammation were compared to better understand lung structure-function relationships. Rats were exposed 21 h/day for 7 days to 0.8 ppm ozone (O{sub 3}), sham-exposed as controls, or given 5 mg/kg bacterial endotoxin either intratracheally (ITE) or intraperitoneally (IPE). Respiratory function was measured 24 h after the end of treatment, than the rats were sacrificed and the distribution of inflammation was evaluated morphometrically. Chronic centriacinar inflammation with formation of new respiratory bronchioles caused an obstructive functional impairment in the O{sub 3} rats, which was clearly distinguished from the restrictive impairments resulting from acute inflammation in ITE and IPE rats. Only the magnitudes of changes related to the distribution of inflammation differentiated the ITE and IPE groups. Flow parameters previously thought sensitive to large airway resistance were changed in the O{sub 3} rats. Alveolar luminal inflammatory exudate affected quasistatic compliance more than septal inflammation in ITE and IPE rats. Quasistatic chord compliance was the most sensitive of three indices of pressure-volume relationships. The findings in this study improve the basis for interpreting respiratory function changes of rats. (author)

Cincotti, V.; D'Andrea, A.

1989-07-01

The DENINT power plant cost benefit analysis code takes into consideration, not only power production costs at the generator terminals, but also, in the case of cogeneration, the costs of the fuel supply and heat and power distribution systems which depend greatly on the location of the plant. The code is able to allow comparisons of alternatives with varying annual operation hours, fuel cost increases, and different types of fossil fuels and production systems. For illustrative purposes, this paper examines two methane fired cogeneration plant/district heating alternatives

Interprofessional education and the basic sciences: Rationale and outcomes.

Thistlethwaite, Jill E

2015-01-01

Interprofessional education (IPE) aims to improve patient outcomes and the quality of care. Interprofessional learning outcomes and interprofessional competencies are now included in many countries' health and social care professions' accreditation standards. While IPE may take place at any time in health professions curricula it tends to focus on professionalism and clinical topics rather than basic science activities. However generic interprofessional competencies could be included in basic science courses that are offered to at least two different professional groups. In developing interprofessional activities at the preclinical level, it is important to define explicit interprofessional learning outcomes plus the content and process of the learning. Interprofessional education must involve interactive learning processes and integration of theory and practice. This paper provides examples of IPE in anatomy and makes recommendations for course development and evaluation. © 2015 American Association of Anatomists.

Robertson, James; Bandali, Karim

2008-10-01

Simulated learning and interprofessional education (IPE) are increasingly becoming more prevalent in health care curriculum. As the focus shifts to patient-centred care, health professionals will need to learn with, from and about one another in real-life settings in order to facilitate teamwork and collaboration. The provision of simulated learning in an interprofessional environment helps replicate these settings thereby providing the traditional medical education model with opportunities for growth and innovation. Learning in context is an essential psychological and cognitive aspect of education.This paper offers a conceptual analysis of the salient issues related to IPE and medical simulation. In addition, the paper argues for the integration of simulation into IPE in order to develop innovative approaches for the delivery of education and improved clinical practice that may benefit students and all members of the health care team.

Hudak, Nicholas M; Melcher, Betsy; Strand de Oliveira, Justine

2017-12-01

This study describes clinical preceptors' perceptions of interprofessional practice, the nature and variety of physician assistant (PA) students' interprofessional interactions during clinical training, and factors that facilitate or hinder interprofessional education (IPE) in clinical settings. This qualitative study involved interviews with preceptors that were audio-recorded, transcribed, and then analyzed through an iterative process to identify key conceptual themes. Fourteen preceptors from a variety of clinical settings participated. Four themes were identified: (1) preceptors define interprofessional practice differently; (2) students learn about teams by being a part of teams; (3) preceptors separate students to avoid diluting learning experiences; and (4) preceptors can facilitate IPE by introducing students to members of the team and role modeling team skills. The themes may inform PA educators' efforts to increase IPE in clinical settings through educational interventions with both preceptors and students.

To determine the impact of simulations using an alternative method of communication on students' satisfaction, attitudes, confidence, and performance related to interprofessional communication. One hundred sixty-three pharmacy students participated in a required applications-based capstone course. Students were randomly assigned to one of three interprofessional education (IPE) simulations with other health professions students using communication methods such as telephone, e-mail, and video conferencing. Pharmacy students completed a validated survey instrument, Attitude Toward Healthcare Teams Scale (ATHCTS) prior to and after course participation. Significant positive changes occurred for 5 out of 20 items. Written reflection papers and student satisfaction surveys completed after participation showed positive themes and satisfaction. Course instructors evaluated student performance using rubrics for formative feedback. Implementation of IPE simulations using various methods of communication technology is an effective way for pharmacy schools to incorporate IPE into their curriculum.

Plant-based diets, defined in terms of low frequency of animal food consumption, have been increasingly recommended for their health benefits. Numerous studies have found plant-based diets, especially when rich in high quality plant foods such as whole grains, fruits, vegetables, and nuts, to be associated with lower risk of cardiovascular outcomes and intermediate risk factors. This review summarizes the current evidence base examining the associations of plant-based diets with cardiovascular endpoints, and discusses the potential biological mechanisms underlying their health effects, practical recommendations and applications of this research, and directions for future research. Healthful plant-based diets should be recommended as an environmentally sustainable dietary option for improved cardiovascular health. Copyright © 2018 Elsevier Inc. All rights reserved.

Baum, J.W.; Dionne, B.J.

1983-01-01

The collective dose equivalent at nuclear power plants increased from 1250 rem in 1969 to nearly 54,000 rem in 1980. This rise is attributable primarily to an increase in nuclear generated power from 1289 MW-y to 29,155 MW-y; and secondly, to increased average plant age. However, considerable variation in exposure occurs from plant to plant depending on plant type, refueling, maintenance, etc. In order to understand the factors influencing these differences, an investigation was initiated to study dose-reduction techniques and effectiveness of as low as reasonably achievable (ALARA) planning at light water plants. Objectives are to: identify high-dose maintenance tasks and related dose-reduction techniques; investigate utilization of high-reliability, low-maintenance equipment; recommend improved radioactive waste handling equipment and procedures; examine incentives for dose reduction; and compile an ALARA handbook

The foundation of the framework for a Severe Accident Management Program is the contained in the Probabilistic Safety Study (PSS) or the Individual Plant Evaluations (IPE) for a specific plant. The development of a Severe Accident Management Program at a plant is based on the use of the information, in conjunction with other applicable information. A Severe Accident Management Program must address both accident prevention and accident mitigation. The overall Severe Accident Management framework must address these two facets, as a living program in terms of gathering the evaluating information, the readiness to respond to an event. Significant international experience in the development of severe accident management programs exist which should provide some direction for the development of Severe Accident Management in the U.S. This paper reports that the two most important elements of a Severe Accident Management Program are the Emergency Consultation process and the standards for measuring the effectiveness of individual Severe Accident Management Programs at utilities

SGEA 2015 CONFERENCE ABSTRACT (EDITED). Evaluating Interprofessional Teamwork During a Large-Scale Simulation. Courtney West, Karen Landry, Anna Graham, and Lori Graham. CONSTRUCT: This study investigated the multidimensional measurement of interprofessional (IPE) teamwork as part of large-scale simulation training. Healthcare team function has a direct impact on patient safety and quality of care. However, IPE team training has not been the norm. Recognizing the importance of developing team-based collaborative care, our College of Nursing implemented an IPE simulation activity called Disaster Day and invited other professions to participate. The exercise consists of two sessions: one in the morning and another in the afternoon. The disaster scenario is announced just prior to each session, which consists of team building, a 90-minute simulation, and debriefing. Approximately 300 Nursing, Medicine, Pharmacy, Emergency Medical Technicians, and Radiology students and over 500 standardized and volunteer patients participated in the Disaster Day event. To improve student learning outcomes, we created 3 competency-based instruments to evaluate collaborative practice in multidimensional fashion during this exercise. A 20-item IPE Team Observation Instrument designed to assess interprofessional team's attainment of Interprofessional Education Collaborative (IPEC) competencies was completed by 20 faculty and staff observing the Disaster Day simulation. One hundred sixty-six standardized patients completed a 10-item Standardized Patient IPE Team Evaluation Instrument developed from the IPEC competencies and adapted items from the 2014 Henry et al. PIVOT Questionnaire. This instrument assessed the standardized or volunteer patient's perception of the team's collaborative performance. A 29-item IPE Team's Perception of Collaborative Care Questionnaire, also created from the IPEC competencies and divided into 5 categories of Values/Ethics, Roles and Responsibilities

Na vigilância epidemiológica dessas endemias, torna-se fundamental o conhecimento da distribuição e ecologia das diferentes espécies de flebotomíneos. Assim, a divulgação de novos registros de seus vetores é fundamental para apontar novas áreas de risco para a transmissão dessas doenças. Neste estudo, realizaram-se capturas de flebotomíneos em ambiente de mata, em diferentes localidades dos municípios de Ipeúna, Itirapina e Analândia, entre agosto e setembro de 2007. Foram capturados 248 flebotomíneos de nove espécies diferentes, em Ipeúna, seis e sete espécimes de duas espécies distintas coletados respectivamente em Itirapina e Analândia. A espécie mais abundante em Ipeúna foi Pintomyia pessoai (37,5%, seguida de P. fischeri (33,06% e Migonemyia migonei (16,53%. Essas três espécies são consideradas importantes vetores de LTA no território paulista.

2015-01-01

The physical properties of biological materials impact their functions. This is most evident in plants where the cell wall contains each cell's contents and connects each cell to its neighbors irreversibly. Examining the physical properties of the plant cell wall is key to understanding how plant cells, tissues, and organs grow and gain the shapes important for their respective functions. Here, we present an atomic force microscopy-based nanoindentation method for examining the elasticity of plant cells at the subcellular, cellular, and tissue level. We describe the important areas of experimental design to be considered when planning and executing these types of experiments and provide example data as illustration. Copyright © 2015 Elsevier Inc.

Effects of arbuscular mycorrhizal fungi and maternal plant sex on seed germination and early plant establishment.

Varga, Sandra

2015-03-01

• Arbuscular mycorrhizal fungi usually enhance overall plant performance, yet their effects on seed germination and early plant establishment, crucial steps in plant cycles, are generally overlooked. In gynodioecious species, sexual dimorphism in these traits has been reported, with females producing seeds that germinate at a faster rate than seeds from hermaphrodites.• Using the gynodioecious plant Geranium sylvaticum, I investigated in a greenhouse experiment whether the presence of arbuscular mycorrhizal spores affects seed germination and early plant establishment, examining at the same time whether the sex of the mother producing the seeds also influences these parameters and whether sex-specific interactions between these two factors exist.• The presence of arbuscular mycorrhizal spores in the soil decreased seed germination, did not affect plant survival, but did increase plant growth. Moreover, no significant differences in seed traits were detected between the sexes of the plants producing the seeds.• This study demonstrates that arbuscular mycorrhizal fungi may have contrasting effects for plants during early life stages and that mycorrhizal effects can take place even at the precolonization stage. © 2015 Botanical Society of America, Inc.

Over 40 species of aquatic angiosperms, including submersed, floating and emergent types, have been examined for photosynthetic status as part of a search for possible aquatic C/sub 4/ species. The C/sub 4/ system is viewed as potentially of adaptive value in certain aquatic situations, although evidence for its occurrence there is not conclusive. Emphasis was on plants from North-temperate softwater and hardwater lakes to explore both possibilities of CO/sub 2/ limitation, i.e., low total inorganic carbon in softwater vs. low free CO/sub 2/ in hardwater lakes. On the basis of leaf cross-section anatomy, all plants examined, with one exception, clearly did not show evidence of C/sub 4/ ''Krantz anatomy.'' In the submersed plant Potamogeton praelongus Wulf, large starch-producing chloroplasts were concentrated in cells surrounding vascular bundles and in a narrow band of cells between vascular bundles. The in situ photosynthetic rate of this plant was twice that of a related species, but other evidence including PEP carboxylase content and photorespiratory response to high O/sub 2/ did not confirm the presence of the C/sub 4/ photosynthesis.

Negative or positive feedback between arbuscular mycorrhizal fungi (AMF) and host plants can contribute to plant species interactions, but how this feedback affects plant invasion or resistance to invasion is not well known. Here we tested how alterations in AMF community induced by an invasive plant species generate feedback to the invasive plant itself and affect subsequent interactions between the invasive species and its native neighbors. We first examined the effects of the invasive forb Solidago canadensis L. on AMF communities comprising five different AMF species. We then examined the effects of the altered AMF community on mutualisms formed with the native legume forb species Kummerowia striata (Thunb.) Schindl. and on the interaction between the invasive and native plants. The host preferences of the five AMF were also assessed to test whether the AMF form preferred mutualistic relations with the invasive and/or the native species. We found that S. canadensis altered AMF spore composition by increasing one AMF species (Glomus geosporum) while reducing Glomus mosseae, which is the dominant species in the field. The host preference test showed that S. canadensis had promoted the abundance of AMF species (G. geosporum) that most promoted its own growth. As a consequence, the altered AMF community enhanced the competitiveness of invasive S. canadensis at the expense of K. striata. Our results demonstrate that the invasive S. canadensis alters soil AMF community composition because of fungal-host preference. This change in the composition of the AMF community generates positive feedback to the invasive S. canadensis itself and decreases AM associations with native K. striata, thereby making the native K. striata less dominant.

Nondestructive examinations performance demonstration standpoint of the BCCN (Nuclear Construction Inspection Office)

Deschamps, J.; Novat, J.

1994-01-01

The part played by in service non-destructive examinations (NDE) in the safety assessment of French nuclear power plants has developed considerably since startup of the first PWR unit 15 years ago. In 15 years of operation and continued plant construction, defects came to light, revealed either by a non-destructive examination or a leak occurring in operation or during hydrostatic test. It is consequently necessary to operate reactors affected by defects already detected or liable to develop according to a known mechanism. This practice is only acceptable if it can be proved that the defects will remain harmless in all situations. This implies that they can be detected without fail beyond a certain threshold, that they can be characterized and that their propensity to develop can be measured. In some cases, only NDE data can justify the continued operation of a reactor. Maximum guarantees as to the performances and reliability of these examinations are consequently indispensable, since plant safety conclusions will be based on their results. This paper discusses: the advantages of an NDE performance demonstration program; practical assessments role; and NDE performance demonstration stages

Korea Electric Power Research Institute (KEPRI) and Korea Hydro and Nuclear Power Company (KHNP) developed Korean Performance Demonstration (KPD) system for ultrasonic examination applicable to pressurized light-water reactor and pressurized heavy-water reactor power plants in accordance with ASME Sec. XI App. VIII. In order to develop the KPD system following works were completed. 1) Surveying the welds on piping of all nuclear power plants in Korea, 2) Surveying the bolting configuration of all nuclear power plant in Korea, 3) Determining the number and type of test specimens, 4)Designing the test and the practice specimens, 5) Developing quality assurance procedures for the fabrication of test specimens and system management, 6) Developing generic procedures for manual ultrasonic test, 7) Fabrication and fingerprint of test specimen. After establishing the KPD system, round robin tests were conducted to evaluate the accuracy and reliability of examination results by comparing traditional ASME code and performance demonstration method. KEPRI/KHNP had successfully developed the KPD system to fulfill the performance demonstration requirements of ASME Sec. XI, Appendix VIII, and are executing the performance demonstration test for ultrasonic examination system. (author)

The aim of this study was to establish the applicability of natural water-ethanol extracts of herbs and spices in increasing the oxidative stability of plant oils and in the production of novel food. Different concentrations (0, 100, 300, 500, and 700 ppm) of spice extracts and butylated hydroxyanisole (BHA) (100 ppm) were added to the studied oils. The antioxidant activity of spice extracts was determined with electron paramagnetic resonance (EPR) spectroscopy using 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical assay. The study showed that the extracts significantly increased the oxidative stability of the examined oils when compared to one of the strongest synthetic antioxidants--BHA. The applied simple production technology and addition of herb and spice extracts to plant oils enabled enhancement of their oxidative stability. The extracts are an alternative to the oils aromatized with an addition of fresh herbs, spices, and vegetables because it did not generate additional flavors thus enabling the maintenance of the characteristic ones. Moreover, it will increase the intake of natural substances in human diet, which are known to possess anticarcinogenic properties. © 2012 Institute of Food Technologists®

These days, our interest in nuclear plant accidents has increased, and civic actions for them have also been activated. Therefore, improvement of the disaster prevention planning to nuclear plant accidents is requested. In this study, we developed a microscopic traffic simulation system for evacuation plan near the nuclear plant as a system which supports to examine the disaster prevention planning, and applied the system to Kashiwazaki-Kariwa nuclear plant area. Furthermore, the risk of each region near the nuclear plant disaster from the viewpoint of wind direction and the population was considered, the importance of each evacuation simulation was examined. As a result, we found that the present plan Kashiwazaki-Kariwa made has the problem on evacuation routes and others. (author)

Relationship of sulfur content of soils and plants

1928-01-01

Crops were fertilized with fertilizers which contained chloride and sulfate in order to examine how the sulfur content of a plant may be affected by that of the soil. At the time of flowering the respective chlorine or sulfate content of the plants was considerably above that of the controls; differences were less, however, when the plants were fully mature. Sulfate, in particular, was little different. In field observations, little correlation was noted between sulfate content of plants and soils. Natural variations in the sulfur content of plants were greater than the increases attributable to smoke air pollution. 2 tables.

Intervention analysis of power plant impact on fish populations

Madenjian, C.P.

1984-01-01

Intervention analysis was applied to 10 yr (years 1973-1982) of field fish abundance data at the D. C. Cook Nuclear Power Plant, southeastern Lake Michigan. Three log-transformed catch series, comprising monthly observations, were examined for each combination of two species (alewife, Alosa pseudoharenga, or yellow perch, Perca flavescens) and gear (trawl or gill net): catch at the plant discharged transect, catch at the reference transect, and the ratio of plant catch to reference catch. Time series separated by age groups were examined. Based on intervention analysis, no change in the abundance of fish populations could be attributed to plant operation. Additionally, a modification of the intervention analysis technique was applied to investigate trends in abundance at both the plant discharge and reference transects. Significant declines were detected for abundance of alewife adults at both of the transects. Results of the trend analysis support the contention that the alewives have undergone a lakewide decrease in abundance during the 1970s

Vascular Plants of the Hanford Site

This report provides an updated listing of the vascular plants present on and near the U.S. Department of Energy Hanford Site. This document is an update of a listing of plants prepared by Sackschewdky et al. in 1992. Since that time there has been a significant increase in the botanical knowledge of the Hanford Site. The present listing is based on an examination of herbarium collections held at PNNL, at WSU-Tri Cities, WSU-Pullman, Brigham Young University, and The University of Washington, and on examination of ecological literature derived from the Hanford and Benton county areas over the last 100 years. Based on the most recent analysis, there are approximately 725 different plant species that have been documented on or around the Hanford Site. This represents an approximate 20% increase in the number of species reported within Sackschewsky et al. (1992). This listing directly supports DOE and contractor efforts to assess the potential impacts of Hanford Site operations

Plant odour plumes as mediators of plant-insect interactions.

Science.gov (United States)

Beyaert, Ivo; Hilker, Monika

2014-02-01

Insect olfactory orientation along odour plumes has been studied intensively with respect to pheromonal communication, whereas little knowledge is available on how plant odour plumes (POPs) affect olfactory searching by an insect for its host plants. The primary objective of this review is to examine the role of POPs in the attraction of insects. First, we consider parameters of an odour source and the environment which determine the size, shape and structure of an odour plume, and we apply that knowledge to POPs. Second, we compare characteristics of insect pheromonal plumes and POPs. We propose a 'POP concept' for the olfactory orientation of insects to plants. We suggest that: (i) an insect recognises a POP by means of plant volatile components that are encountered in concentrations higher than a threshold detection limit and that occur in a qualitative and quantitative blend indicating a resource; (ii) perception of the fine structure of a POP enables an insect to distinguish a POP from an unspecific odorous background and other interfering plumes; and (iii) an insect can follow several POPs to their sources, and may leave the track of one POP and switch to another one if this conveys a signal with higher reliability or indicates a more suitable resource. The POP concept proposed here may be a useful tool for research in olfactory-mediated plant-insect interactions. © 2013 The Authors. Biological Reviews © 2013 Cambridge Philosophical Society.

SYMPOSIUM ON PLANT PROTEIN PHOSPHORYLATION

2011-11-01

Protein phosphorylation and dephosphorylation play key roles in many aspects of plant biology, including control of cell division, pathways of carbon and nitrogen metabolism, pattern formation, hormonal responses, and abiotic and biotic responses to environmental signals. A Symposium on Plant Protein Phosphorylation was hosted on the Columbia campus of the University of Missouri from May 26-28, 2010. The symposium provided an interdisciplinary venue at which scholars studying protein modification, as it relates to a broad range of biological questions and using a variety of plant species, presented their research. It also provided a forum where current international challenges in studies related to protein phosphorylation could be examined. The symposium also stimulated research collaborations through interactions and networking among those in the research community and engaged students and early career investigators in studying issues in plant biology from an interdisciplinary perspective. The proposed symposium, which drew 165 researchers from 13 countries and 21 States, facilitated a rapid dissemination of acquired knowledge and technical expertise regarding protein phosphorylation in plants to a broad range of plant biologists worldwide.

Casimiro, Lynn; MacDonald, Colla J; Thompson, Terrie Lynn; Stodel, Emma J

2009-07-01

Interprofessional care (IPC) is a prerequisite for enhanced communication between healthcare team members, improved quality of care, and better outcomes for patients. A move to an IPC model requires changing the learning experiences of healthcare providers during and after their qualification program. With the rapid growth of online and blended approaches to learning, an educational framework that explains how to construct quality learning events to provide IPC is pressing. Such a framework would offer a quality standard to help educators design, develop, deliver, and evaluate online interprofessional education (IPE) programs. IPE is an extremely delicate process due to issues related to knowledge, status, power, accountability, personality traits, and culture that surround IPC. In this paper, a review of the pertinent literature that would inform the development of such a framework is presented. The review covers IPC, IPE, learning theories, and eLearning in healthcare.

2016-01-01

Interprofessional education (IPE) is the basis for interprofessional collaboration (IPC) in health care systems. It has beneficial effects for both patients and health care professionals. IPC is paramount for adequate care of patients and their families, especially in pediatrics. To determine the attitudes of medical doctors (n=121), nurses (n=15), psychologists (n=14), and social workers (n=19) toward IPE and IPC in a tertiary pediatric university teaching hospital, as well as the inpatient and outpatient settings in pediatrics, we developed a questionnaire with 21 items in four categories based on established questionnaires. All participants worked as part of interprofessional teams, and the overwhelming majority valued IPC highly. Most competencies important for IPC were acquired on the job. There was a substantial lack of interprofessional education, especially for medical doctors and psychologists. IPE still needs to be established as part of the undergraduate curriculum at German universities.

2016-01-01

The importance of interprofessional collaboration in achieving high quality outcomes, improving patient quality of life, and decreasing costs has been growing significantly in health care. Palliative care has been viewed as an exemplary model of interprofessional care delivery, yet best practices in both interprofessional education (IPE) and interprofessional practice (IPP) in the field are still developing. So, too, is the leadership of hospice and palliative care social workers within IPE and IPP. Generating evidence regarding best practices that can prepare social work professionals for collaborative practice is essential. Lessons learned from practice experiences of social workers working in hospice and palliative care can inform educational efforts of all professionals. The emergence of interprofessional education and competencies is a development that is relevant to social work practice in this field. Opportunities for hospice and palliative social workers to demonstrate leadership in IPE and IPP are presented in this article.

Interprofessional education in Erlangen: A needs analysis and the conceptual work of a student working group.

Konietzko, Raffael; Frank, Luca; Maudanz, Nils; Binder, Johannes

2016-01-01

Interprofessional education (IPE) is receiving growing significance both nationally and internationally. Despite this, organizational and curricular changes are posing challenges. The level of need for IPE and how changes can be made to curricula and infrastructure were investigated at the University of Erlangen in Germany. The student working group for interprofessional teaching (AGIL) has turned its attention to these issues. This group is composed of students from medicine, dentistry, molecular medicine, medical technology and speech therapy. In June, 2015, a needs analysis was carried out among the students in the study programs represented in the working group to assess the actual and target situation concerning IPE (n=1,105). In the search for answers and to better measure any needs, contact was sought with instructors. The majority of students feel that they are insufficiently educated in terms of interprofessional skills. A large proportion of the students wish to see expansion of the IPE offerings. Students also expressed a desire for additional spaces and welcomed the idea of an interprofessional learning center. AGIL began establishing interprofessional electives in October 2015. A concept for an interprofessional learning center was developed. Based on the survey results, a need for improvements to curricula and infrastructure can be seen; however, the results are limited to the student point of view. AGIL would like to establish more interprofessional electives. These courses would then facilitate curricular implementation. Modern ideas about study environments could be applied to IPE, in particular to promote informal forms of learning. Contact with instructors was crucial for the project work and should be expanded. Realizing and financing the learning center in Erlangen are now the future goals of AGIL. The aim is to create a foundation for this purpose.

Systematic Review and Meta-analysis of Indirect Protection Afforded by Vaccinating Children Against Seasonal Influenza: Implications for Policy.

2017-09-01

Universal childhood vaccination is a potential solution to reduce seasonal influenza burden. We reviewed systematically the literature on "herd"/indirect protection from vaccinating children aged 6 months to 17 years against influenza. Of 30 studies included, 14 (including 1 cluster randomized controlled trial [cRCT]) used live attenuated influenza vaccine, 11 (7 cRCTs) used inactivated influenza vaccine, and 5 (1 cRCT) compared both vaccine types. Twenty of 30 studies reported statistically significant indirect protection effectiveness (IPE) with point estimates ranging from 4% to 66%. Meta-regression suggests that studies with high quality and/or sufficiently large sample size are more likely to report significant IPE. In meta-analyses of 6 cRCTs with full randomization (rated as moderate quality overall), significant IPE was found in 1 cRCT in closely connected communities where school-aged children were vaccinated: 60% (95% confidence interval [CI], 41%-72%; I2 = 0%; N = 2326) against laboratory-confirmed influenza, and 3 household cRCTs in which preschool-aged children were vaccinated: 22% (95% CI, 1%-38%; I2 = 0%; N = 1903) against acute respiratory infections or influenza-like illness. Significant IPE was also reported in a large-scale cRCT (N = 8510) that was not fully randomized, and 3 ecological studies (N > 10000) of moderate quality including 36% reduction in influenza-related mortality among the elderly in a Japanese school-based program. Data on IPE in other settings are heterogeneous and lacked power to draw a firm conclusion. The available evidence suggests that influenza vaccination of children confers indirect protection in some but not all settings. Robust, large-scaled studies are required to better quantify the indirect protection from vaccinating children for different settings/endpoints. © The Author 2017.

Research needs for risk-informed, performance-based regulation

International Nuclear Information System (INIS)

Bailey, J.A.

1997-01-01

Palo Verde Nuclear Generating Station has used PRA-derived risk insights for about 10 years now. The plant originally started applying PRA modeling to an auxiliary feedwater system during the initial licensing phases of the plant, and as a result of that, they were able to work with the NRC and apply some graded quality requirements to that particular system. There was a third redundant auxiliary feedwater pump, and they now can treat that system as partially safety related and partially non-safety related. So it was an advance for Palo Verde at that time to be able to make decisions with a PRA and they began learning how to use those techniques. After completing the IPE it became natural for the plant to make a transition into other areas at the plant to look for areas where the insights gained from PRA could be applied into their decision-making processes. Those that the plant embarked upon initially were areas where they could gain operational risk assessment insights. The author goes on to discuss experiences gained in using these techniques to better assess the safety of operations within the plant. In addition he offers comments on areas which need further development and research to make them more applicable to a plant by plant basis

Vascular plants structure wetland ecosystems. To examine mechanisms behind their influence, plants were studied under different scenarios of change: experimental manipulation of cover, invasion, and response to flushing regimes. I tested the hypothesis that wetland plants alter benthic communities through modification of abiotic factors, with cascading effects on microalgae and invertebrate communities. Major plant effects were observed in all systems studied, but the magnitude of, mechanisms...

Dissecting through barriers: A mixed-methods study on the effect of interprofessional education in a dissection course with healthcare professional students.

Fernandes, Alisha Rebecca; Palombella, Andrew; Salfi, Jenn; Wainman, Bruce

2015-01-01

Healthcare delivery is reliant on a team-based approach, and interprofessional education (IPE) provides a means by which such collaboration skills can be fostered prior to entering the workplace. IPE within healthcare programs has been associated with improved collaborative behavior, patient care and satisfaction, reduced clinical error, and diminished negative professional stereotypes. An intensive interprofessional gross anatomy dissection course was created in 2009 to facilitate IPE at McMaster University. Data were collected from five cohorts over five years to determine the influence of this IPE format on the attitudes and perceptions of students towards other health professions. Each year, 28 students from the medicine, midwifery, nursing, physician's assistant, physiotherapy, and occupational therapy programs were randomly assigned into interprofessional teams for 10 weeks. Sessions involved an anatomy and scope-of-practice presentation, a small-group case-based session, and a dissection. A before/after design measured changes in attitudes and perceptions, while focus group data elaborated on the student experience with the course. Pre- and postmatched data revealed significant improvements in positive professional identity, competency and autonomy, role clarity and attitudes toward other health professions. Qualitative analysis of intraprofessional focus group interviews revealed meaningful improvements in a number of areas including learning anatomy, role clarity, and attitudes towards other health professions. © 2015 American Association of Anatomists.

The perception of strigolactones in vascular plants.

Lumba, Shelley; Holbrook-Smith, Duncan; McCourt, Peter

2017-05-17

Small-molecule hormones play central roles in plant development, ranging from cellular differentiation and organ formation to developmental response instruction in changing environments. A recently discovered collection of related small molecules collectively called strigolactones are of particular interest, as these hormones also function as ecological communicators between plants and fungi and between parasitic plants and their hosts. Advances from model plant systems have begun to unravel how, as a hormone, strigolactone is perceived and transduced. In this Review, we summarize this information and examine how understanding strigolactone hormone signaling is leading to insights into parasitic plant infections. We specifically focus on how the development of chemical probes can be used in combination with model plant systems to dissect strigolactone's perception in the parasitic plant Striga hermonthica. This information is particularly relevant since Striga is considered one of the largest impediments to food security in sub-Saharan Africa.

The environmental impact from an offshore plant

Wind measurements in different countries have shown the existence of a large energy potential in offshore winds. Taking into consideration the limited suitable area on land for wind power plants it is essential to know the environmental influence from and on an offshore plant. The first offshore wind power plant was built in Sweden in 1990 in order to examine the influence on birds, fish and fishing, shipping, public opinion, maintenance and the effects on foundation from waves and ice. So far, the programme shows that the birds try to avoid the plant by flying further away from it out over the sea. (Author)

Taplin, C.

Methyl jasmonate (MJ) is a compound naturally occurring in certain plants that aids in plant defense. In this study, we examined the difference in herbivory of fall armyworm (FAW) on control plants (treated without MJ) and MJ-treated plants. Seeds of cheniere rice and soybean were soaked in MJ overnight and planted in the greenhouse, although the soybean never grew. Therefore, only the mature plant leaves of cheniere rice were fed to FAW and the difference in herbivory was looked at. Our results show there is no statistical difference in the herbivory of the cheniere rice plant leaves.

Arthropod assemblages on native and nonnative plant species of a coastal reserve in California.

Fork, Susanne K

Biological invasions by nonnative plant species are a widespread phenomenon. Many studies have shown strong ecological impacts of plant invasions on native plant communities and ecosystem processes. Far fewer studies have examined effects on associated animal communities. From the perspective of a reserve's land management, I addressed the question of whether arthropod assemblages on two nonnative plant species of concern were impoverished compared with those assemblages associated with two predominant native plant species of that reserve. If the nonnative plant species, Conium maculatum L., and Phalaris aquatica L., supported highly depauperate arthropod assemblages compared with the native plant species, Baccharis pilularis De Candolle and Leymus triticoides (Buckley) Pilger, this finding would provide additional support for prioritizing removal of nonnatives and restoration of natives. I assessed invertebrate assemblages at the taxonomic levels of arthropod orders, Coleoptera families, and Formicidae species, using univariate analyses to examine community attributes (richness and abundance) and multivariate techniques to assess arthropod assemblage community composition differences among plant species. Arthropod richness estimates by taxonomic level between native and nonnative vegetation showed varying results. Overall, arthropod richness of the selected nonnative plants, examined at higher taxonomic resolution, was not necessarily less diverse than two of common native plants found on the reserve, although differences were found among plant species. Impacts of certain nonnative plant species on arthropod assemblages may be more difficult to elucidate than those impacts shown on native plants and ecosystem processes.

In-plant studies examining the effects of entrainment on zooplankton and field studies examining zooplankton abundance, composition, and distribution in the Chesapeake Bay in the vicinity of Calvert Cliffs Nuclear Power Plant have been conducted from 1974 to the present. The evolution of these studies, with particular emphasis on design and statistical treatment, is discussed. Entrainment study designs evolved from discrete sampling episodes at 4-h intervals over 24 h to a time-series sampling design in which sampling took place every 30 min over 24 and 48-h periods. The near-field study design and samping methods have included replicated net tows, using 0.5-m nets, and replicated and nonreplicated pumped sampling, using a high-speed centrifugal pump. 16 refs

The complex challenge of evaluating the impact of interprofessional education (IPE) on patient and community health outcomes is well documented. Recently, at the Radcliffe Institute for Advanced Study in the United States, leaders in health professions education met to help generate a direction for future IPE evaluation research. Participants followed the stages of design thinking, a process for human-centred problem solving, to reach consensus on recommendations. The group concluded that future studies should focus on measuring an intermediate step between learning activities and patient outcomes. Specifically, knowing how IPE-prepared students and preceptors influence the organisational culture of a clinical site as well as how the culture of clinical sites influences learners' attitudes about collaborative practice will demonstrate the value of educational interventions. With a mixed methods approach and an appreciation for context, researchers will be able to identify the factors that foster effective collaborative practice and, by extension, promote patient-centred care.

Interprofessional learning activities, such as workshops allow students to learn from, with and about each other. This study assessed the impact on Indonesian health students' attitudes towards interprofessional education (IPE) from participating in a workshop on medication safety. The students attended a two-day IPE workshop on medication safety. Thirty-five (48.6%) students completed pre-/post-workshop surveys using a modified Readiness for Interprofessional Learning Scale (RIPLS) survey. The post-workshop survey also had a series of open-ended questions. Students' responses to each RIPLS statement pre-/post-workshop were compared, whilst their responses to open-ended questions in post-workshop survey were thematically analysed. Students reported positive attitudinal changes on statements of shared learning and teamwork sub-scale (Wilcoxon p value importance of teamwork and communication skills. This study found that learning with other health students through an IPE workshop improved medical, nursing and pharmacy students' attitudes towards the importance of shared learning, teamwork and communication in healthcare service.

Proposal of a broadband, polarization-insensitive and high-efficiency hot-carrier schottky photodetector integrated with a plasmonic silicon ridge waveguide

2015-01-01

We propose a broadband, polarization-insensitive and high-efficiency plasmonic Schottky diode for detection of sub-bandgap photons in the optical communication wavelength range through internal photoemission (IPE). The distinctive features of this design are that it has a gold film covering both the top and the sidewalls of a dielectric silicon ridge waveguide with the Schottky contact formed at the gold–silicon interface and the sidewall coverage of gold can be easily tuned by an insulating layer. An extensive physical model on IPE of hot carriers is presented in detail and is applied to calculate and examine the performance of this detector. In comparison with a diode having only the top gold contact, the polarization sensitivity of the responsivity is greatly minimized in our photodetector with gold film covering both the top and the sidewall. Much higher responsivities for both polarizations are also achieved over a broad wavelength range of 1.2–1.6 μm. Moreover, the Schottky contact is only 4 μm long, leading to a very small dark current. Our design is very promising for practical applications in high-density silicon photonic integration. (paper)

VARIATION IN THE SENSITIVITY OF WANDERING JEW PLANTS TO GLUFOSINATE AMMONIUM

Full Text Available This study aimed to identify the response of wandering jew (Commelina benghalensis L. plants to different doses of glufosinate ammonium and the sensitivity of plants populations to the herbicide. Two studies were conducted, both in a greenhouse, and were repeated at different times. In the first study, two experiments were conducted to examine the dose-response curve using seven different doses of the glufosinate ammonium herbicide (0, 50, 100, 200, 400, 800, and 1600 g a.i. ha-1 with four replicates each. In the second study, which examined the range in sensitivity of wandering jew plants to glufosinate ammonium, 26 plants were sprayed with a dose of 200 g a.i. ha-1 herbicide. Visual assessments of percent injury and measurements of leaf tissue ammonium content were conducted. The use of untreated wandering jew control plants allowed for the correlation of glufosinate ammonium treatment with the ammonium concentrations in treated plant tissues; the ammonium concentration increased as a function of herbicide application, albeit not linearly with the dose. Ammonium content varied among individuals of the wandering jew plant population.

Tossavainen, K.

1991-12-01

The Finnish nuclear power plant units Loviisa 1 and 2 as well as TVO 1 and II were in operation for almost the whole second quarter of 1991. The load factor average was 87.4 %. In consequence of a fire, which broke out in the switchgear building, connections to both external grids were lost and TVO II relied on power supplied by four back-up diesels for 7.5 hrs. The event is classified as Level 2 on the International Nuclear Event Scale. The process of examining the non-leaking fuel bundles removed from the Loviisa nuclear reactors has continued. The examinations have revealed, so far, that the uppermost spacing lattices of the bundles exhibit deformations similar to those detected in the leaking fuel bundles removed from the reactors. This event is classified as Level 1 on the International Nuclear Event Scale. Other events in this quarter which are classified according to the International Nuclear Event Scale are Level Zero (Below Scale) on the Scale. The Finnish Centre for Radiation and Nuclear Safety has assessed the safety of the Loviisa and Olkiluoto nuclear power plants based on the new regulations issued on 14.2.1991 by the Council of State. The safety regulations are much more stringent than those in force when the Loviisa and Olkiluoto nuclear power plants were built. The assessment indicated that the TVO nuclear power plant meets these safety regulations. The Loviisa nuclear power plant meets the requirements with the exception of certain requirements related to the ensuring of safety functions and provision for accidents. At the Loviisa nuclear power plant there are several projects under consideration to enhance safety

The aim of this study is to describe the state of the art of large combustion plants with respect to the European directive on integrated pollution prevention and control (IPPC-Directive 96/61/EG). For this purpose 10 sites where one or more thermal power or district heating plants with a rated thermal input of > 50 MW are operated were selected and described in detail. Only coal and oil fired power plants were chosen because of the larger environmental impacts compared to gas fired combustion units. Large industrial combustion plants, where in addition to regular fuels also special fuels and wastes are combusted (e.g. power plants from refineries and from the pulp and paper industry), and waste incineration plants are not treated in this study. The depiction of power plants comprises the whole chain of operation, starting from the description of the type and composition of fuels, the pretreatment and introduction into the boiler, the firing technology, measures for emission reduction (both into air and water) and treatment of solid waste and residues from combustion. Furthermore possibilities to increase energy efficiency and economic aspects are examined in this study. Also legal aspects are shortly described at the beginning of the respective chapters. An actual topic is co-combustion of biomass and waste in thermal power plants. Results of trial operation in Austrian power plants are summarized and conclusions were drawn with respect to environmental impacts of co-incineration, such as emissions into air and water, quality of solid wastes and residues from co-incineration. Important aspects such as shifting of pollutants and dilution effects are discussed. The study concludes with the chapter 'State of the art for power plants', which gives a survey of the relevant measures with particular attention to above mentioned crucial points. (author)

Aluminum (Al) stress is one of the serious limiting factors in plant productivity in acidic soils, which constitute about 50 % of the world's potentially arable lands and causes anywhere between 25 and 80 % of yield losses depending upon the species. The mechanism of Al toxicity and tolerance has been examined in plants, which is vital for crop improvement and enhanced food production in the future. Two mechanisms that facilitate Al tolerance in plants are Al exclusion from the roots and the ability to tolerate Al in the symplast or both. Although efforts have been made to unravel Al-resistant factors, many aspects remain unclear. Certain gene families such as MATE, ALMT, ASR, and ABC transporters have been implicated in some plants for resistance to Al which would enhance the opportunities for creating crop plants suitable to grow in acidic soils. Though QTLs have been identified related to Al-tolerance, no crop plant that is tolerant to Al has been evolved so far using breeding or molecular approaches. The remarkable changes that plants experience at the physiological, biochemical and molecular level under Al stress, the vast array of genes involved in Al toxicity-tolerance, the underlying signaling events and the holistic image of the molecular regulation, and the possibility of creating transgenics for Al tolerance are discussed in this review.

Knowledge and abilities catalog for nuclear power plant operators: Boiling water reactors, Revision 1

International Nuclear Information System (INIS)

1995-08-01

The Knowledge and Abilities Catalog for Nuclear Power Plant Operators: Boiling-Water Reactors (BWRs) (NUREG-1123, Revision 1) provides the basis for the development of content-valid licensing examinations for reactor operators (ROs) and senior reactor operators (SROs). The examinations developed using the BWR Catalog along with the Operator Licensing Examiner Standards (NUREG-1021) and the Examiner's Handbook for Developing Operator Licensing Written Examinations (NUREG/BR-0122), will cover the topics listed under Title 10, Code of Federal Regulations, Part 55 (10 CFR 55). The BWR Catalog contains approximately 7,000 knowledge and ability (K/A) statements for ROs and SROs at BWRs. The catalog is organized into six major sections: Organization of the Catalog, Generic Knowledge and Ability Statements, Plant Systems grouped by Safety Functions, Emergency and Abnormal Plant Evolutions, Components, and Theory. Revision 1 to the BWR Catalog represents a modification in form and content of the original catalog. The K/As were linked to their applicable 10 CFR 55 item numbers. SRO level K/As were identified by 10 CFR 55.43 item numbers. The plant-wide generic and system generic K/As were combined in one section with approximately one hundred new K/As. Component Cooling Water and Instrument Air Systems were added to the Systems Section. Finally, High Containment Hydrogen Concentration and Plant Fire On Site evolutions added to the Emergency and Abnormal Plant Evolutions section

Integration of torrefaction with steam power plant

Energy Technology Data Exchange (ETDEWEB)

Zakri, B.; Saari, J.; Sermyagina, E.; Vakkilainen, E.

2013-09-01

Torrefaction is one of the pretreatment technologies to enhance the fuel characteristics of biomass. The efficient and continuous operation of a torrefaction reactor, in the commercial scale, demands a secure biomass supply, in addition to adequate source of heat. Biorefinery plants or biomass-fuelled steam power plants have the potential to integrate with the torrefaction reactor to exchange heat and mass, using available infrastructure and energy sources. The technical feasibility of this integration is examined in this study. A new model for the torrefaction process is introduced and verified by the available experimental data. The torrefaction model is then integrated in different steam power plants to simulate possible mass and energy exchange between the reactor and the plants. The performance of the integrated plant is investigated for different configurations and the results are compared. (orig.)

Elevated levels of 129 I, a long-lived fission product, are present in the environment as a result of nuclear weapons testing and fuel reprocessing. To aid in understanding the anomalous behavior of this element, relative to natural I ( 127 I), in the vicinity of nuclear fuel reprocessing plants, preliminary laboratory-growth chamber studies were undertaken to examine the possible formation of volatile inorganic and organic I species in soil and plant systems. Inorganic 129 I added to soil was volatilized from both the soil and plant during plant growth, at average ratios of 2 x 10 -3 %/day soil and 9 x 10 -3 %/day foliage, respectively. Volatilization rates from soil were an order of magnitude less in the absence of growing roots. Less than 2% of soil or plant volatiles was subsequently retained by plant canopies. Volatile I, chemically characterized by selective sorption methods, consisted principally of alkyl iodides formed by both soil and plant processes. However, plants and soils containing actively growing roots produced a larger fraction of volatile inorganic I than soil alone. 14 refs., 1 fig., 3 tabs

Repowering options for steam power plants

Repowering an existing steam power plant with a gas turbine offers an attractive alternative to a new plant or life extension, especially for unit sizes smaller than 300 MWe. Gas turbine repowering improves thermal efficiency and substantially increases the plant output. Based on recent repowering studies and projects, this paper examines gas turbine repowering options for 100 MWe, 200 MWe and 300 MWe units originally designed for coal firing and currently firing either coal or natural gas. Also discussed is the option for a phased future conversion of the repowered unit to fire coal-derived gas, should there be a fluctuation in the price or availability of natural gas. A modular coal gasification plant designed to shorten the conversion time is presented. Repowering options, performance, costs, and availability impacts are discussed for selected cases

Cogeneration plant noise: Environmental impacts and abatement

De Renzio, M.; Ciocca, B.

1991-01-01

In Italy, ever increasing attention to environmental problems has led to legislation requiring cogeneration plant owners to perform environmental impact assessments in order to determine plant conformity with pollution laws. This paper, based on an in-depth analysis of physics fundamentals relevant to the nature and effects of noise, examines the principal sources of noise in industrial cogeneration plants and the intensity and range of the effects of this noise on the local environment. A review is then made of the different methods of noise pollution abatement (e.g., heat and corrosion resistant silencers for gas turbines, varying types and thicknesses of acoustic insulation placed in specific locations) that can be effectively applied to cogeneration plant equipment and housing

Plant host finding by parasitic plants: a new perspective on plant to plant communication.

Science.gov (United States)

Mescher, Mark C; Runyon, Justin B; De Moraes, Consuelo M

2006-11-01

Plants release airborne chemicals that can convey ecologically relevant information to other organisms. These plant volatiles are known to mediate a large array of, often complex, interactions between plants and insects. It has been suggested that plant volatiles may have similar importance in mediating interactions among plant species, but there are few well-documented examples of plant-to-plant communication via volatiles, and the ecological significance of such interactions has been much debated. To date, nearly all studies of volatile-mediated interactions among plant species have focused on the reception of herbivore-induced volatiles by neighboring plants. We recently documented volatile effects in another system, demonstrating that the parasitic plant Cuscuta pentagona uses volatile cues to locate its hosts. This finding may broaden the discussion regarding plant-to-plant communication, and suggests that new classes of volatile-meditated interactions among plant species await discovery.

Issues regarding ownership and transfer arrangements of natural gas processing facilities are reviewed. Means by which to determine the worth of a processing plant (capacity, throughput, process fees, plant limitation, reservoir capability, gathering system capacity, production to reserve ratios), the valuation process and the risks to consider are also examined. In the final analysis the mark of fair market value is a successfully completed negotiation. It should represent a win-win situation for both the plant owner and the gas producer

Environmental conditions influence the plant functional diversity effect on potential denitrification.

Full Text Available Global biodiversity loss has prompted research on the relationship between species diversity and ecosystem functioning. Few studies have examined how plant diversity impacts belowground processes; even fewer have examined how varying resource levels can influence the effect of plant diversity on microbial activity. In a field experiment in a restored wetland, we examined the role of plant trait diversity (or functional diversity, (FD and its interactions with natural levels of variability of soil properties, on a microbial process, denitrification potential (DNP. We demonstrated that FD significantly affected microbial DNP through its interactions with soil conditions; increasing FD led to increased DNP but mainly at higher levels of soil resources. Our results suggest that the effect of species diversity on ecosystem functioning may depend on environmental factors such as resource availability. Future biodiversity experiments should examine how natural levels of environmental variability impact the importance of biodiversity to ecosystem functioning.

Pinellas Plant feasibility study. Final report

NONE

1994-09-01

The Pinellas Plant was built in 1956 to manufacture neutron generators, a principal component in nuclear weapons. In September 1990, the Department of Health and Rehabilitative Services (HRS) entered into an agreement with DOE to independently examine environmental monitoring data from the plant and health data from Pinellas County to determine if an epidemiological study is technically feasible to measure possible off-site health effects from ionizing radiation. Through normal plant operations, some radioactive materials have been released to the environment. Eighty percent of the total plant releases of 107,707 curies occurred in the early years of plant operation (1957--1960). The primary materials released were tritium gas, tritium oxide and krypton-85. Environmental monitoring for radioactive releases from the plant has been done regularly since 1975. The US Public Health Service Centers for Disease Control and Prevention (CDC), in assisting HRS, has determined that sufficient radiological data exist by which a dose reconstruction can be done. A dose reconstruction can provide an estimate of how much radiological exposure someone living in the vicinity of the Pinellas Plant may have suffered from environmental releases.

Doi, Atsushi; Sakaguchi, Toshiaki

1986-01-01

The present study is aimed at constructing a knowledge base for supervisory control operation in power plants and developing an operation guidance by using it. Examination is made to provide dignosis procedures on the basis of an existing alarm system. An operation guidance procedure for diagnosis is proposed which is to be followed when several alarms are sounded simultaneously in a power plant, and application of the procedure to an existing plant is examined. The operation manual for the plant includes 75 description items for six alarms. It is shown that the number of items related to these alarms can be reduced by 70 % by rearranging them according to the procedure. Another investigation is conducted to provide an operation manual for diagnosis to be used when one alarm is sounded in a plant. The quality of the manual developed is on nearly the same level with that for the existing plant examined. When a knowledge base is to be constructed from an existing operation manual, the processing operation generally requires a certain level of linguistic comprehension ability, such as for judgment of synonyms. It is demonstrated that the procedure proposed here is able to develop a high-quality knowledge base with standardized terminology. The procedure can also serve to construct operation manuals for plants in other industrial fields. (Nogami, K.)
