    Full Text Available The users’ rising need for relevant, reliable, coherent, timely data for the early diagnosis of the economic vulnerability and of the turning points in the business cycles, especially during a financial and economic crisis, asks for a prompt answer, coordinated by statistical institutions. High quality short term statistics are of special interest for the emerging market economies, such as the Moldavian one, being extremely vulnerable when facing economic recession. Answering to the challenges of producing a coherent and adequate image of the economic activity, by using the system of indicators and definitions efficiently applied at the level of the European Union, the National Bureau of Statistics (NBS of the Republic of Moldova has launched the development process of an integrated system of short term statistics (STS based on the advanced international experience.Thus, in 2011, BNS implemented the integrated statistical survey on STS based on consistent concepts, harmonized with the EU standards. The integration of the production processes, which were previously separated, is based on a common technical infrastructure, standardized procedures and techniques for data production. The achievement of this complex survey with holistic approach has allowed the consolidation of the statistical data quality, comparable at European level and the signifi cant reduction of information burden on business units, especially of small size.The reformation of STS based on the integrated survey has been possible thanks to the consistent methodological and practical support given to NBS by the National Institute of Statistics (INS of Romania, for which we would like to thank to our Romanian colleagues.

    term experiments to implement novel observational systems. Through active collaboration with the teams in charge of the experiments, users will take advantage of the site characterization, historical data, monitoring setup and access to different treatments experimental field with differentiated properties induced by repeated treatment. • Access to soil and vegetation samples collected at different dates that may be reanalyzed a posteriori to take profit of technological progress. • Delivery of reference data on ecosystems subjected to a gradient of anthropogenic and climatic pressures. The research infrastructure level is appropriate to implement a harmonization policy for the measurement and observation protocols. Moreover it offers the possibility of developing an ambitious strategy in integrating data and models. These can contribute to the experimental process for protocol design or data quality control. Moreover, they offer an efficient way for promoting data reuse thus giving a strong added value to the existing data bases. Therefore, building interoperability between models and experimental platform data bases is an important objective to improve the quality of experimental infrastructure and provide users with seamless and integrated information systems. We present how this is operated in AnaEE-France with different tasks as the development of a controlled vocabulary, tools to annotate data and model variables with metadata based on ontologies and the development of webservice to harvest data from the data base to the modelling platform environment. Finally some examples of key results taking profit of the range of experiments are provided.

    2017-01-01

    Term by term integration may lead to divergent integrals, and naive evaluation of them by means of, say, analytic continuation or by regularization or by the finite part integral may lead to missing terms. Here, under certain analyticity conditions, the problem of missing terms for the incomplete Stieltjes transform, ∫0af (x )(ω+x ) -1 dx , and the Stieltjes transform itself, ∫0∞f (x )(ω+x ) -1 dx , is resolved by lifting the integration in the complex plane. It is shown that the missing terms arise from the singularities of the complex-valued function f(z)(ω+z)-1, with the divergent integrals arising from term by term integration interpreted as finite part integrals.

    2016-05-02

    There is growing concern that short-term experiences in global health experiences (STEGH), undertaken by healthcare providers, trainees, and volunteers from high income countries in lower and middle income countries, risk harming the community by creating a parallel system of care separate from established community development efforts. At the same time, the inclusion of non-traditional actors in health planning has been the basis of the development of many Healthy Community Partnerships (HCP) being rolled out in Canada and the United States. These partnerships aim to bring all stakeholders with a role to play in health to the table to align efforts, goals and programs towards broad community health goals. This methodology paper reports on the process used in La Romana, Dominican Republic, in applying a modified HCP framework. This project succeeded at bringing visiting STEGH organizations into a coalition with key community partners and supported attempts to embed the work of STEGH within longer-term, established development plans. In presenting the work and process and lessons learned, the hope is that other communities that encounter significant investment from STEGH groups, and will gain the same benefits that were seen in La Romana with regards to improved information exchange, increased cross-communication between silos, and the integration of STEGH into the work of community partners.

    Schaeffer, Hayden; McCalla, Scott G.

    2017-08-01

    Model selection and parameter estimation are important for the effective integration of experimental data, scientific theory, and precise simulations. In this work, we develop a learning approach for the selection and identification of a dynamical system directly from noisy data. The learning is performed by extracting a small subset of important features from an overdetermined set of possible features using a nonconvex sparse regression model. The sparse regression model is constructed to fit the noisy data to the trajectory of the dynamical system while using the smallest number of active terms. Computational experiments detail the model's stability, robustness to noise, and recovery accuracy. Examples include nonlinear equations, population dynamics, chaotic systems, and fast-slow systems.

    Full Text Available In this work the laboratory experimental practice with the analysis of environmental problems were related. The aim of this paper was to analyze a proposal that linked experimental work with the local environment situation to promote care for nature and its use with sustainability. This strategy gave an integrated approach to provide teachers training a learning alternative with simple experiences for the qualitative study of the local environment and motivate the analysis of associated problems. The experiences allowed characterize soil, water and air samples of the students’ residence. The experimental information boosted the discussion of the current environmental situation. The teaching approach based on socio-scientific problems allowed an interdisciplinary view of the issue, resizing values and actions for environmental protection and sustainable development.

  10. Short-Term Research Experiences with Teachers in Earth and Planetary Sciences and a Model for Integrating Research into Classroom Inquiry

    Science.gov (United States)

    Morgan, P.; Bloom, J. W.

    2006-12-01

    For the past three summers, we have worked with in-service teachers on image processing, planetary geology, and earthquake and volcano content modules using inquiry methods that ended with mini-research experiences. Although almost all were science teachers, very few could give a reasonable definition of science at the start of the modules, and very few had a basic grasp of the processes of scientific research and could not include substantive scientific inquiry into their lessons. To build research understanding and confidence, an instructor-student interaction model was used in the modules. Studies have shown that children who participate in classrooms as learning and inquiry communities develop more complex understandings. The same patterns of complex understandings have resulted in similarly structured professional communities of teachers. The model is based on professional communities, emphasizing from the beginning that inquiry is a form of research. Although the actual "research" component of the modules was short, the teachers were identified as professionals and researchers from the start. Research/inquiry participation is therefore an excellent example by which to allow their teachers to learn. Initially the teachers were very reluctant to pose questions. As they were encouraged to share, collaborate, and support each other, the role of the instructor became less of a leader and more of a facilitator, and the confidence of the teachers as professionals and researchers grew. One teacher even remarked, "This is how we should be teaching our kids!' Towards the end of the modules the teachers were ready for their mini- research projects and collaborated in teams of 2-4. They selected their own research topics, but were guided toward research questions that required data collection (from existing studies), some data manipulation, interpretation, and drawing conclusions with respect to the original question. The teachers were enthusiastic about all of their

  11. GPFS HPSS Integration: Implementation Experience

    Energy Technology Data Exchange (ETDEWEB)

    Hazen, Damian; Hick, Jason

    2008-08-12

    In 2005 NERSC and IBM Global Services Federal began work to develop an integrated HSM solution using the GPFS file system and the HPSS hierarchical storage system. It was foreseen that this solution would play a key role in data management at NERSC, and fill a market niche for IBM. As with many large and complex software projects, there were a number of unforeseen difficulties encountered during implementation. As the effort progressed, it became apparent that DMAPI alone could not be used to tie two distributed, high performance systems together without serious impact on performance. This document discusses the evolution of the development effort, from one which attempted to synchronize the GPFS and HPSS name spaces relying solely on GPFS?s implementation of the DMAPI specification, to one with a more traditional HSM functionality that had no synchronized namespace in HPSS, and finally to an effort, still underway, which will provide traditional HSM functionality, but requires features from the GPFS Information Lifecycle Management (ILM) to fully achieve this goal in a way which is scalable and meets the needs of sites with aggressive performance requirements. The last approach makes concessions to portability by using file system features such as ILM and snapshotting in order to achieve a scalable design.

  13. Naturalization fosters the long-term political integration of immigrants

    2015-01-01

    Does naturalization cause better political integration of immigrants into the host society? Despite heated debates about citizenship policy, there exists almost no evidence that isolates the independent effect of naturalization from the nonrandom selection into naturalization. We provide new evidence from a natural experiment in Switzerland, where some municipalities used referendums as the mechanism to decide naturalization requests. Balance checks suggest that for close naturalization referendums, which are decided by just a few votes, the naturalization decision is as good as random, so that narrowly rejected and narrowly approved immigrant applicants are similar on all confounding characteristics. This allows us to remove selection effects and obtain unbiased estimates of the long-term impacts of citizenship. Our study shows that for the immigrants who faced close referendums, naturalization considerably improved their political integration, including increases in formal political participation, political knowledge, and political efficacy.

    Full Text Available In the contemporary world the intensity of the immigration movements is constantly increasing. Countries which experience great immigrant flows are facing numerous problems which should be solved. The article studies the current immigration flows in EU countries, the United States of America and Canada and presents three main models of integration policy towards immigrants – political assimilation, functional integration and multicultural model. Separate models are distinguished for the Muslims’ integration. The author examines the peculiarities of every model and examines the conclusions provided by the Migrant Integration Policy Index (MIPEX concerning the situation of the immigrants’ integration in 31 countries in 2011. Among all the policy indicators the first that are defined are as follows: political participation, education, labour market mobility and anti-discrimination. The situation with immigrants’ integration in Ukraine is also studied as it is gaining a great attention of the authorities and the public. The measures and practical steps done regarding this situation in Ukraine in recent years are analyzed using the information offered by the State Migration Service of Ukraine.

    Full Text Available Purpose: Health care reform in the United States has introduced terms such as “the patient-centered medical home” and “integrated care” that are often unclear and unfamiliar to patients. This study explored patient experiences with the functional domains of integrated care. Theory and methods: Patients first wrote their definitions of integrated care and then participated in focus group discussions about their experiences with the health care system. Transcripts were analyzed for thematic content. Results: Forty-four patients participated in one of seven focus groups in San Francisco, CA in English and Spanish. Many patients were not clear about the meaning of the term integrated care. However, patients described experiences largely reflected in an existing conceptual model of integrated care and the importance of coordination within and across teams and with community resources, continuity and sharing of information, and patient engagement. Patients with high medical needs described the ubiquitous challenges they faced in experiencing coordinated care. Conclusions: Patients may not understand the term integrated care but are relatively clear on what the concept of integrated care entails and support its successful implementation. Patients and their families are at the center of integrated care, and health systems need to support and empower them to successfully navigate the medical neighborhood.

  16. Integrating mental health services: the Finnish experience

    Ville Lehtinen

    2001-06-01

    Full Text Available The aim of this paper is to give a short description of the most important developments of mental health services in Finland during the 1990s, examine their influences on the organisation and provision of services, and describe shortly some national efforts to handle the new situation. The Finnish mental health service system experienced profound changes in the beginning of the 1990s. These included the integration of mental health services, being earlier under own separate administration, with other specialised health services, decentralisation of the financing of health services, and de-institutionalisation of the services. The same time Finland underwent the deepest economic recession in Western Europe, which resulted in cut-offs especially in the mental health budgets. Conducting extensive national research and development programmes in the field of mental health has been one typically Finnish way of supporting the mental health service development. The first of these national programmes was the Schizophrenia Project 1981–97, whose main aims were to decrease the incidence of new long-term patients and the prevalence of old long-stay patients by developing an integrated treatment model. The Suicide Prevention Project 1986–96 aimed at raising awareness of this special problem and decreasing by 20% the proportionally high suicide rate in Finland. The National Depression Programme 1994–98 focused at this clearly increasing public health concern by several research and development project targeted both to the general population and specifically to children, primary care and specialised services. The latest, still on-going Meaningful Life Programme 1998–2003 which main aim is, by multi-sectoral co-operation, to improve the quality of life for people suffering from or living with the threat of mental disorders. Furthermore, the government launched in 1999 a new Goal and Action Programme for Social Welfare and Health Care 2000–2003, in

    Very early in the Space Launch Initiative program, a small team of engineers at MSFC proposed a process for performing system-level assessments of a launch vehicle. Aimed primarily at providing insight and making NASA a smart buyer, the Vehicle Integrated Performance Analysis (VIPA) team was created. The difference between the VIPA effort and previous integration attempts is that VIPA a process using experienced people from various disciplines, which focuses them on a technically integrated assessment. The foundations of VIPA s process are described. The VIPA team also recognized the need to target early detailed analysis toward identifying significant systems issues. This process is driven by the T-model for technical integration. VIPA s approach to performing system-level technical integration is discussed in detail. The VIPA process significantly enhances the development and monitoring of realizable project requirements. VIPA s assessment validates the concept s stated performance, identifies significant issues either with the concept or the requirements, and then reintegrates these issues to determine impacts. This process is discussed along with a description of how it may be integrated into a program s insight and review process. The VIPA process has gained favor with both engineering and project organizations for being responsive and insightful

    Full Text Available Long term preservation of electronic data requires introduction of specific technology solutions and organizational measures in order to provide stable environment for electronic record preservation. System solutions must support basic principles of electronic preservation: accessibility of data, usability or reproduction of data in usable form and integrity/authenticity provision including time existence for preserved content.Due to their nature, electronic data may become subjects of manipulation without recursive traceability of content alteration. In order to preserve usability of preserved data, electronic preservation system must provide appropriate measures for demonstrating unalterability of data for the entire preservation period. In this paper technology approach for demonstrating integrity and authenticity of archived data on long term basis is presented. Presented technological concept deals with any type of documentation or archiving material and provides creation of additional security assertions or evidence records that are needed to demonstrate the authenticity and integrity of the material anytime during the archival period. The evidence record syntax (ERS, which has been standardized by international organization body for internet standards (IETF, presents universal technique of security assertions generation and their maintenance for integrity preservation based on document hashing, hash treeing and integration of (qualified time stamps of trusted third parties. Using re-timestamping methods created security assertions may endure their validity for longest periods of time until retention periods of archived data expires. In the paper complementary organizational rules for technology solutions are presented as well, providing an all around overview of long term preservation of data in authentic, reliable and secure manner.

    As a researcher, I have studied the efforts to increase the integration of health and social services in Quebec, as well as the mergers in the Quebec healthcare system. These mergers have often been presented as a necessary transition to break down the silos that compartmentalize the services dispensed by various organisations. A review of the studies about mergers and integrated care projects in the Quebec healthcare system, since its inception, show that mergers cannot facilitate integrated care unless they are desired and represent for all of the actors involved an appropriate way to deal with service organisation problems. Otherwise, mergers impede integrated care by creating increased bureaucratisation and standardisation and by triggering conflicts and mistrust among the staff of the merged organisations. It is then preferable to let local actors select the most appropriate organisational integration model for their specific context and offer them resources and incentives to cooperate.

    The purpose of this report is to define the Short-Term Integrated Forecasting System (STIFS) and describe its basic properties. The Energy Information Administration (EIA) of the US Energy Department (DOE) developed the STIFS model to generate short-term (up to 8 quarters), monthly forecasts of US supplies, demands, imports exports, stocks, and prices of various forms of energy. The models that constitute STIFS generate forecasts for a wide range of possible scenarios, including the following ones done routinely on a quarterly basis: A base (mid) world oil price and medium economic growth. A low world oil price and high economic growth. A high world oil price and low economic growth. This report is written for persons who want to know how short-term energy markets forecasts are produced by EIA. The report is intended as a reference document for model analysts, users, and the public.

    The promise of inertial fusion energy driven by heavy ion beams requires the development of accelerators that produce ion currents (approx 100's Amperes/beam) and ion energies ({approx} 1 - 10 GeV) that have not been achieved simultaneously in any existing accelerator. The high currents imply high generalized perveances, large tun depressions, and high space charge potentials of the beam center relative to the beam pipe. Many of the scientific issues associated with ion beams of high perveance and large tune depression have been addressed over the last two decades on scaled experiments at Lawrence Berkeley and Lawrence Livermore National Laboratories, the University of Maryland, and elsewhere. The additional requirement of high space charge potential (or equivalently high line charge density) gives rise to effects (particularly the role of electrons in beam transport) which must be understood before proceeding to a large scale accelerator. The first phase of a new series of experiments in the Heavy Ion Fusion Virtual National Laboratory (HIF VNL), the High Current Experiments (HCX), is now beginning at LBNL. The mission of the HCX is to transport beams with driver line charge density so as to investigate the physics of this regime, including constraints on the maximum radial filling factor of the beam through the pipe. This factor is important for determining both cost and reliability of a driver scale accelerator. The HCX will provide data for design of the next steps in the sequence of experiments leading to an inertial fusion energy power plant. The focus of the program after the HCX will be on integration of all of the manipulations required for a driver. In the near term following HCX, an Integrated Beam Experiment (IBX) of the same general scale as the HCX is envisioned. The step which bridges the gap between the IBX and an engineering test facility for fusion has been designated the Integrated Research Experiment (IRE). The IRE (like the IBX) will

    2006-01-01

    To build a common controlled vocabulary is a formidable challenge in medical informatics. Due to vast scale and multiplicity in interpretation of medical data, it is natural to face overlapping terminologies in the process of practicing medical informatics [A. Rector, Clinical terminology: why is it so hard? Methods Inf. Med. 38 (1999) 239-252]. A major concern lies in the integration of seemingly overlapping terminologies in the medical domain and this issue has not been well addressed. In this paper, we describe a novel approach for medical ontology integration that relies on the theory of Algorithmic Semantic Refinement we previously developed. Our approach simplifies the task of matching pairs of corresponding concepts derived from a pair of ontologies, which is vital to terminology mapping. A formal theory and algorithm for our approach have been devised and the application of this method to two medical terminologies has been developed. The result of our work is an integrated medical terminology and a methodology and implementation ready to use for other ontology integration tasks.

  9. Researchers' Experiences, Positive and Negative, in Integrative Landscape Projects

    2005-12-01

    Integrative (interdisciplinary and transdisciplinary) landscape research projects are becoming increasingly common. As a result, researchers are spending a larger proportion of their professional careers doing integrative work, participating in shifting interdisciplinary teams, and cooperating directly with non-academic participants. Despite the growing importance of integrative research, few studies have investigated researchers’ experiences in these projects. How do researchers perceive the outcomes of integrative projects, or career effects? Do they view the projects generally as successes or failures? This study analyses researchers’ experiences in integrative landscape studies and investigates what factors shape these experiences. The data stems from 19 semi-structured qualitative interviews and a Web-based survey among 207 participants in integrative landscape research projects. It finds that researchers experience participation in integrative projects as positive, in particular discussions among participants, networking, teamwork, and gaining new insights and skills. Furthermore, most researchers perceive the projects as successful and as having a positive effect on their careers. Less positive aspects of integration relate to publications and merit points. Factors found to contribute to positive experiences include reaching a high degree of integration amongst the involved disciplines, common definitions of integrative research concepts, and projects that include a large share of fundamental research as well as projects with many project outcomes. Based on these findings, we advise future projects to plan for integration, facilitate discussions, and reach agreement on integrative concepts. We suggest that aspects of fundamental research be included in integrative projects. We also suggest that planning be done at an early stage for peer-reviewed publications, to ensure that participants gain merit points from their participation in integrative research

We suggest that aspects of fundamental research be included in integrative projects. We also suggest that planning be done at an early stage for peer-reviewed publications, to ensure that participants gain merit points from their participation in integrative research

    TBI often results in reduced social participation. This decrease in social participation is independent of injury severity and time since injury. Thus, it is one of the many stable hallmarks of TBI. Changes in social participation have been related to many factors, including emotional dysregulation and disturbance and executive dysfunction. While there are evidenced-based treatments available to improve mood and executive functioning, none of the research has examined the impact of the various treatments on social participation or social integration. Therefore, while it is reasonable to expect that individuals who are feeling better about themselves and who improve their approach to day-to-day function will also experience increased social contact, there is no evidence to support this claim. This chapter reviews the literature on post-TBI social integration and its relationship to depression and executive dysfunction. In addition the intervention research in this area is briefly examined. © 2015 Elsevier B.V. All rights reserved.

    Information from structural genomics experiments at the RIKEN SPring-8 Center, Japan has been compiled and published as an integrated database. The contents of the database are (i) experimental data from nine species of bacteria that cover a large variety of protein molecules in terms of both evolution and properties (http://database.riken.jp/db/bacpedia), (ii) experimental data from mutant proteins that were designed systematically to study the influence of mutations on the diffraction quality of protein crystals (http://database.riken.jp/db/bacpedia) and (iii) experimental data from heavy-atom-labelled proteins from the heavy-atom database HATODAS (http://database.riken.jp/db/hatodas). The database integration adopts the semantic web, which is suitable for data reuse and automatic processing, thereby allowing batch downloads of full data and data reconstruction to produce new databases. In addition, to enhance the use of data (i) and (ii) by general researchers in biosciences, a comprehensible user interface, Bacpedia (http://bacpedia.harima.riken.jp), has been developed.

  13. Introducing the term 'Biocontrol Plants' for integrated pest management

    Directory of Open Access Journals (Sweden)

    2014-02-01

    Full Text Available Studies of interactions between crops, additional plants, pests and beneficial organisms already exist as well as studies of natural enemy preference, dispersal, and abundance. However, these studies focus on tri-trophic interactions from an "arthropod" point of view. We think that in order to optimize crop protection methods we need to understand the effects that plant structures have on the various arthropods and on subsequent tri-trophic interactions. Although studies and reviews describing the role of secondary plants in Integrated Pest Management (IPM exist, to date a general term which encompasses all plants added to a cropping system with the aim of enhancing IPM strategies has yet to be formulated. Therefore, we suggest a new term, "biocontrol plants", which we define as plants that are intentionally added to a crop system with the aim of enhancing crop productivity through pest attraction and/or pest regulation; a term that will promote the use of biocontrol services, and can ultimately lead to an increase in the sustainability of cropping systems.

    High energy particle physics experiments investigate the nature of matter through the identification of subatomic particles produced in collisions of protons, electrons, or heavy ions which have been accelerated to very high energies. Future experiments will have hundreds of millions of detector channels to observe the interaction region where collisions take place at a 40 MHz rate. This paper gives an overview of the electronics requirements for such experiments and explains how data reduction, timing distribution, and radiation tolerance in commercial CMOS circuits are achieved for these big systems. As a detailed example, the electronics for the innermost layers of the future tracking detector, the pixel vertex detector, is discussed with special attention to system aspects. A small-scale prototype (130 channels) implemented in standard 0.25 mu m CMOS remains fully functional after a 30 Mrad(SiO/sub 2/) irradiation.

    Climate variability is a major source of uncertainty for the insurance industry underwriting hurricane risk. Catastrophe models provide their users with a stochastic set of events that expands the scope of the historical catalogue by including synthetic events that are likely to happen in a defined time-frame. The use of these catastrophe models is widespread in the insurance industry but it is only in recent years that climate variability has been explicitly accounted for. In the insurance parlance "medium term catastrophe model" refers to products that provide an adjusted view of risk that is meant to represent hurricane activity on a 1 to 5 year horizon, as opposed to long term models that integrate across the climate variability of the longest available time series of observations. In this presentation we discuss how a simple reinsurance program can be used to assess the value of medium term catastrophe models. We elaborate on similar concepts as discussed in "Potential Economic Value of Seasonal Hurricane Forecasts" by Emanuel et al. (2012, WCAS) and provide an example based on 24 years of historical data of the Chicago Mercantile Hurricane Index (CHI), an insured loss proxy. Profit and loss volatility of a hypothetical primary insurer are used to score medium term models versus their long term counterpart. Results show that medium term catastrophe models could help a hypothetical primary insurer to improve their financial resiliency to varying climate conditions.

  20. Integrating short-term and long-term forecasting with reservoir optimisation; Mantaro Basin, Peru.

    Science.gov (United States)

    Jensen, R. A.; Lasarte, A.; Butts, M. B.

    2009-04-01

    Operational water management often requires a trade-off between short-term and long-term water demands, where short-term demands are driven for example by hydropower generation and flood protection requirements and the long-term demands by water and irrigation supply, sustainable reservoir management and the seasonal impacts of snow melt or climate. This paper presents an operational decision support system designed to forecast and optimise reservoir operations in both the short-term and long-term. The system has been established for the 20,000 km2 Mantaro river basin located in the high Andes with altitudes ranging from 3500 to nearly 6000 m.a.s.l.. The two main power stations at Tablachaca have a combined capacity of more than 1000 MW that supplies 30% of Peru's electrical energy. In addition, the basin's water resources supply extensive agricultural areas, an urban population and mining activities and sustain important ecological habitats. In this paper, the methodologies used for the integrating short-term and long-term forecasting are presented together with their application to the optimal operation of reservoirs. A key element in the system is the MIKE BASIN modelling tool. The system uses several modelling capabilities of MIKE BASIN: rainfall-runoff, reservoir operation, hydropower production, and river flow routing. The system also takes advantage of long-term forecasts (based on statistical information) and short-term forecasts (based on telemetry data). The continually updated runoff and flow forecasts enter the optimization, which applies the Model Predictive Control principle for MIKE BASIN as the core simulation model. For each optimization, a non-linear program algorithm is used to find the best release strategy. On the basis of the forecasted inflows and the real time data the system suggests to the user from which reservoirs to release water for alleviation of possible forecasted deficits. In addition to the Tablachaca scheme the model accounts for

    The ability to safely control highly dynamic systems is of prime importance to designers. Whether the system is an aircraft, spacecraft, or propulsion system, control system designers must turn to test laboratories not only to verify and validate the control systems, but also to actually use the laboratory as a design and development tool. The use of the laboratory early in the development phase of a system—prior to committing to actual hardware/software (HW/SW)—permits early detection of system anomalies, thereby minimizing program development costs while enhancing safety. Later the laboratory can be used to train system operators (for example, pilots, ground crew) in preparation for flight/ground test. In the case of the statically unstable X-29 forward swept wing aircraft, a comprehensive real-time, hardware-in-the-loop test facility was critical in the development of the aircraft's digital fly-by-wire (FBW) flight control system. The X-29 laboratory initially was used to introduce control laws to a simulated real-time environment to verify control system characteristics. Later, actual flight hardware was introduced to the laboratory, at which point the formal system verification/validation test program began. The test program utilized detailed test plans and procedures derived from system requirements and specifications to map out all tests required. This assured that the maximum number of components of the system were exercised in the laboratory, and all components tested had traceability throughout the test program. The end-to-end hardware-in-the loop simulation provided the environment to perform critical failure modes testing, parameter sensitivity evaluation and ultimately pilot/ground crew training during normal and degraded flight control system operation. The X-29 test experience, applicable to the laboratory testing of all critical control systems, has ingrained the philosophy that successful development of complex systems requires an orderly build

    Short-term memory (STM) and long-term memory (LTM) have traditionally been considered cognitively distinct. However, it is known that STM can improve when to-be-remembered information appears in contexts that make contact with prior knowledge, suggesting a more interactive relationship between STM and LTM. The current study investigated whether the ability to leverage LTM in support of STM critically depends on the integrity of the hippocampus. Specifically, we investigated whether the hippocampus differentially supports between-domain versus within-domain STM-LTM integration given prior evidence that the representational domain of the elements being integrated in memory is a critical determinant of whether memory performance depends on the hippocampus. In Experiment 1, we investigated hippocampal contributions to within-domain STM-LTM integration by testing whether immediate verbal recall of words improves in MTL amnesic patients when words are presented in familiar verbal contexts (meaningful sentences) compared to unfamiliar verbal contexts (random word lists). Patients demonstrated a robust sentence superiority effect, whereby verbal STM performance improved in familiar compared to unfamiliar verbal contexts, and the magnitude of this effect did not differ from that in controls. In Experiment 2, we investigated hippocampal contributions to between-domain STM-LTM integration by testing whether immediate verbal recall of digits improves in MTL amnesic patients when digits are presented in a familiar visuospatial context (a typical keypad layout) compared to an unfamiliar visuospatial context (a random keypad layout). Immediate verbal recall improved in both patients and controls when digits were presented in the familiar compared to the unfamiliar keypad array, indicating a preserved ability to integrate activated verbal information with stored visuospatial knowledge. Together, these results demonstrate that immediate verbal recall in amnesia can benefit from two

    The assimilation model is a qualitative and integrative approach that enables to study change processes that occur in psychotherapy. According to Stiles, this model conceives the individual's personality as constituent of different voices; the concept of voice is used to describe traces left by past experiences. During the psychotherapy, we can observe the progressive integration of the problematic voices into the patient's personality. We applied the assimilation model to a 34-session-long case of an effective short-term dynamic psychotherapy. We've chosen eight sessions we transcribed and analyzed by establishing points of contact between the case and the theory. The results are presented and discussed in terms of the evolution of the main voices in the patient.

    Crapenhoft-Gatewood, Kelly Lynn

    The purpose of conducting this study was to describe the experiences of average to high-achieving, middle-income students in a newly implemented integrated science course at a Midwest inner-city high school. The focus of this study was to describe the meaning students ascribed to their experiences in this non-tracked, two-year science course, in which many of the suggestions made by science reform efforts were implemented. A phenomenological approach was used in order to develop a holistic picture of the student participants' experiences. Data collection was confined to interviewing, observing, and analyzing the journals of four middle-income, average to high-achieving students enrolled in the same class during the 1994-95 school year. The data were subjective perceptions of the students in their learning environment. A modified version of the Colaizzi method of analysis of phenomenological data was used. This design utilized the Epoche, Phenomenological Reduction, Imaginative Variation and Synthesis. Co-researchers' statements were clustered into horizons of meaning and organized into themes. The textural themes included curriculum, instruction, teachers, peers, and overall impressions. Relationships to time and interactions with peers and teachers were among the structural themes. From these themes, individual and composite textual descriptions were developed. With the addition of the structural components, an integrated composite textual-structural description of the students' experience in the integrated science course resulted. This final product captured the meanings and essences of their experience. This study adds to the scholarly literature and research as it relates to the implementation of progressive pedagogy and theory regarding student experiences in a science course. It will improve educational practice by helping educators make informed decisions regarding curriculum reform, instructional practices, and classroom environment. This study will also

    This paper examines knowledge exchange dynamics in a specialist integrated intellectual (learning) disability service, comprising specialist healthcare provision with social care commissioning and management, and considers their significance in terms of integrated service delivery. A qualitative study focusing on knowledge exchange and integrated services. Semi-structured interviews (n = 25) were conducted with members of an integrated intellectual disability service in England regarding their perceptions of knowledge exchange within the service and the way in which knowledge exchange impinges on the operation of the integrated service. Exchange of 'explicit' (codifiable) knowledge between health and care management components of the service is problematic because of a lack of integrated clinical governance and related factors such as IT and care record systems and office arrangements. Team meetings and workplace interactions allowed for informal exchange of explicit and 'tacit' (non-codifiable) knowledge, but presented challenges in terms of knowledge exchange completeness and sustainability. Knowledge exchange processes play an important role in the functioning of integrated services incorporating health and care management components. Managers need to ensure that knowledge exchange processes facilitate both explicit and tacit knowledge exchange and do not rely excessively on informal, 'ad hoc' interactions. Research on integrated services should take account of micro-scale knowledge exchange dynamics and relationships between social dynamics and physical factors. © 2014 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

    2016-05-01

    Popular saturations-based nonlinear controller usually include proportional and derivative components of the state or output. The fact that in many applications, these components do not suffice to insure the convergence to the desired output values, motivate the addition of an integral term. In this paper, three configurations of nonlinear controllers based on saturation functions are improved with an integral component. The stability of the three algorithms is analysed using the Lyapunov theory. Simulation results validate the proposed control laws when they are applied to nonlinear systems with constant and unknown perturbations. Real-time experiments realised with a quad-rotor aerial vehicle and a hovercraft vehicle show that the proposed scheme can follow autonomously some trajectories, and that it could be robust with respect to delays.

    International experiences with power sector restructuring and the resultant impacts on bulk power grid operations and planning may provide insight into policy questions for the evolving United States power grid as resource mixes are changing in response to fuel prices, an aging generation fleet and to meet climate goals. Australia, Germany, Japan and the UK were selected to represent a range in the level and attributes of electricity industry liberalization in order to draw comparisons across a variety of regions in the United States such as California, ERCOT, the Southwest Power Pool and the Southeast Reliability Region. The study draws conclusions through a literature review of the four case study countries with regards to the changing resource mix and the electricity industry sector structure and their impact on grid operations and planning. This paper derives lessons learned and synthesizes implications for the United States based on answers to the above questions and the challenges faced by the four selected countries. Each country was examined to determine the challenges to their bulk power sector based on their changing resource mix, market structure, policies driving the changing resource mix, and policies driving restructuring. Each countries’ approach to solving those changes was examined, as well as how each country’s market structure either exacerbated or mitigated the approaches to solving the challenges to their bulk power grid operations and planning. All countries’ policies encourage renewable energy generation. One significant finding included the low- to zero-marginal cost of intermittent renewables and its potential negative impact on long-term resource adequacy. No dominant solution has emerged although a capacity market was introduced in the UK and is being contemplated in Japan. Germany has proposed the Energy Market 2.0 to encourage flexible generation investment. The grid operator in Australia proposed several approaches to maintaining

    Full Text Available Radiotracer experiments are carried out in order to determine the mean residence time (MRT as well as percentage of dead zone, Vdead (%, in an integrated mixer consisting of Rushton and pitched blade turbine (PBT. Conventionally, optimization was performed by varying one parameter and others were held constant (OFAT which lead to enormous number of experiments. Thus, in this study, a 4-factor 3-level Taguchi L9 orthogonal array was introduced to obtain an accurate optimization of mixing efficiency with minimal number of experiments. This paper describes the optimal conditions of four process parameters, namely, impeller speed, impeller clearance, type of impeller, and sampling time, in obtaining MRT and Vdead (% using radiotracer experiments. The optimum conditions for the experiments were 100 rpm impeller speed, 50 mm impeller clearance, Type A mixer, and 900 s sampling time to reach optimization.

  16. CANDU fuel long-term storage and used-fuel integrity

    2005-12-15

    Technologies for long-term dry storage in helium or air have been developed for used CANDU fuel. Used fuel dry storage facilities are presently in operation or under construction at all Canadian nuclear power stations. The evaluation of long-term integrity of stored used fuel started in 1977. Direct examination of fuel stored under water for up to 27 years has indicated that CANDU fuel, defected or not, could be safely stored. The Easily Retrievable Basket and Controlled Environment Experiments have provided information about potential impacts of aging mechanisms during used fuel storage in air for times up to 20 years. The used fuel aging investigation focused on four mechanisms that are believed could have long term impact on used fuel integrity: Stress Corrosion Cracking (SCC), UO2 oxidation, creep and Hydrogen Assisted Cracking (HAC). As a result it was concluded that under normal dry storage conditions it is unlikely that CANDU fuel will suffer significant degradation during a period of 100 years. Additional investigation is still necessary in the areas where there is a higher uncertainty in the prediction of used fuel condition and for the degradation processes that are potentially more aggressive. Additional work is also necessary to evaluate the possible effects of abnormal/accident conditions on the integrity of fuel. In 2004 a new program on used fuel integrity was started. The outlines of this program will be discussed. In the first phase of this project, the focus is on a review of the used fuel characteristics at the beginning of dry storage, and on studies of likely stresses that the fuel will be exposed to during handling and transportation after dry storage. In addition, preservation of relevant information (form and content) about the used fuel during a 100-year period is also being studied. In the first phase most of the investigation is carried out by Nuclear Safety Solutions (NSS). After the first phase additional examination and testing of used

    The LHC experiments are currently preparing for data acquisition in 2007 and because of the large amount of required computing and storage resources, they decided to embrace the grid paradigm. The LHC Computing Project (LCG) provides and operates a computing infrastructure suitable for data handling, Monte Carlo production and analysis. While LCG offers a set of high level services, intended to be generic enough to accommodate the needs of different Virtual Organizations, the LHC experiments software framework and applications are very specific and focused on the computing and data models. The LCG Experiment Integration Support team works in close contact with the experiments, the middleware developers and the LCG certification and operations teams to integrate the underlying grid middleware with the experiment specific components. The strategical position between the experiments and the middleware suppliers allows EIS team to play a key role at communications level between the customers and the service provi...

    Multiomics experiments are increasingly commonplace in biomedical research and add layers of complexity to experimental design, data integration, and analysis. R and Bioconductor provide a generic framework for statistical analysis and visualization, as well as specialized data classes for a variety of high-throughput data types, but methods are lacking for integrative analysis of multiomics experiments. The MultiAssayExperiment software package, implemented in R and leveraging Bioconductor software and design principles, provides for the coordinated representation of, storage of, and operation on multiple diverse genomics data. We provide the unrestricted multiple 'omics data for each cancer tissue in The Cancer Genome Atlas as ready-to-analyze MultiAssayExperiment objects and demonstrate in these and other datasets how the software simplifies data representation, statistical analysis, and visualization. The MultiAssayExperiment Bioconductor package reduces major obstacles to efficient, scalable, and reproducible statistical analysis of multiomics data and enhances data science applications of multiple omics datasets.

    Full Text Available Introduction: In 2000, Japan implemented a mandatory long-term care insurance system. With the rapid growth of the system, problems became apparent. Several critical alterations were made to the long-term care insurance system, particularly with respect to integrated care. Methods: This paper elucidates the policy trends that led to the reforms of the long-term care insurance system, which included new concepts of ‘integrated care’ and ‘community-based care’, an agenda of cost containment and service streamlining, and coordination with medical care. Results: Community-based integrated care, as envisaged in the long-term care policy, includes not only the integration of medical care into service provision but also the inclusion of the informal mutual aid, oversight of for-profit providers by an administration that ensures users are not exploited and coordination between systems that cover different geographical areas. Conclusions: Japan’s experience in community-based care integration suggests that this project requires multi-faceted care integration in local communities. In the future, it will be necessary to conduct empirical assessments of the effectiveness of these measures.

    Town, R. P. J.; Welch, D. R.

    2005-10-01

    Modeling high energy density physics applications driven by short-pulse lasers requires the integration of many areas of physics that operate on disparate spatial and temporal scales. To perform such modeling in one integrated code would be computationally prohibitive, therefore we use the python scripting language to couple together independent hydrodynamics, explicit particle-in-cell (PIC) (Z3), implicit hybrid PIC (LSP), and atomic physics codes (FLYCHK) into one virtual code. This paper will briefly review the integration methodology and outline the new physics packages that have recently been added to LSP. We will contrast our simulation approach with those pursued by other researchers. We will present integrated simulation results of recent Petawatt Kα radiography, electron transport, and isochoric heating experiments and show predictions of a proof-of-principle NIF fast ignition experiment. This work was performed under the auspices of the U.S. Department of Energy by the University of California, Lawrence Livermore National Laboratory under contract No. W-7405-Eng-48.

    In the frame of a US-DOE sponsored project, ANL, BNL, INL and LANL have performed a joint multidisciplinary research activity in order to explore the combined use of integral experiments and covariance data with the objective to both give quantitative indications on possible improvements of the ENDF evaluated data files and to reduce at the same time crucial reactor design parameter uncertainties. Methods that have been developed in the last four decades for the purposes indicated above have been improved by some new developments that benefited also by continuous exchanges with international groups working in similar areas. The major new developments that allowed significant progress are to be found in several specific domains: a) new science-based covariance data; b) integral experiment covariance data assessment and improved experiment analysis, e.g., of sample irradiation experiments; c) sensitivity analysis, where several improvements were necessary despite the generally good understanding of these techniques, e.g., to account for fission spectrum sensitivity; d) a critical approach to the analysis of statistical adjustments performance, both a priori and a posteriori; e) generalization of the assimilation method, now applied for the first time not only to multigroup cross sections data but also to nuclear model parameters (the "consistent" method). This article describes the major results obtained in each of these areas; a large scale nuclear data adjustment, based on the use of approximately one hundred high-accuracy integral experiments, will be reported along with a significant example of the application of the new "consistent" method of data assimilation.

    The neuropeptide 'oxytocin' (OT) is known to play a pivotal role in a variety of complex social behaviors by promoting a prosocial attitude and interpersonal bonding. Previous studies showed that a single-dose of exogenously administered OT can affect trust and feelings of attachment insecurity. With the present study, we explored the effects of two weeks of daily OT administration on measures of state and trait attachment using a double-blind between-subjects randomized placebo-controlled design. In 40 healthy young adult men state and trait attachment were assessed before and after two weeks of daily intranasal OT (24 IU) or placebo using the State Adult Attachment Scale and the Inventory of Parent and Peer Attachment. Mood, social responsiveness and quality of life were additionally assessed as secondary outcome measures. Reductions in attachment avoidance and increases in reports of attachment toward peers were reported after two weeks of OT treatment. Further, treatment-induced changes were most pronounced for participants with less secure attachment towards their peers. indicating that normal variance at baseline modulated treatment response. OT treatment was additionally associated with changes in mood, indicating decreases in feelings of tension and (tentatively) anger in the OT group, not in the placebo group. Further, at the end of the two-week trial, both treatment groups (OT, placebo) reported to experience an increase in social responsiveness and quality of life, but the effects were only specific to the OT-treatment in terms of reports on 'social motivation'. In summary, the observed improvements on state and trait dimensions of attachment after a multiple-dose treatment with OT provide further evidence in support of a pivotal role of OT in promoting the experience of attachment.

    To obtain physician assistant (PA) student perceptions about an interprofessional education (IPE) training experience embedded in a multidisciplinary science course. An IPE training experience was integrated into a graduate human physiology course offered to PA, physical therapy, and graduate studies students. The focus of the activity related to the Interprofessional Education Collaborative (IPEC) competency domains of (1) roles and responsibilities and (2) teams and teamwork. Effectiveness was assessed in pretraining and posttraining surveys, which included questions addressing student self-perceptions of IPEC competency domains, student assessment of the learning activity, and student reflection. We observed a statistically significant positive change in PA student perceptions of IPEC competency domains. Students also provided a positive evaluation of the IPE activity and communicated personal improvements in IPE perspectives. Incorporating planned IPE experiences into multidisciplinary health science courses represents an appropriate venue for PA students to learn and apply interprofessional competencies, which may benefit future interprofessional practice.

    The Harvard Medical School Cambridge Integrated Clerkship is a longitudinal integrated clerkship that has provided an alternative clinical model for medical education in psychiatry since its inception in 2004. This study was undertaken in an effort to better understand the student experience of the Cambridge Integrated Clerkship and how it may have impacted students' perceptions of and interest in psychiatry, as well as performance. Qualitative surveys were sent via e-mail to the first 11 student cohorts who had completed the Cambridge Integrated Clerkship (from 2004 to 2014) and for whom we had e-mail addresses (N = 100), and the free-text responses were coded thematically. All available standardized scoring data and residency match data for Cambridge Integrated Clerkship graduates were obtained. From 2006 to 2014, 12 out of 73 Cambridge Integrated Clerkship students who entered the match chose a psychiatry residency (16.4%), four times more than students in traditional clerkships at Harvard Medical School (3.8% of 1355 students) or the national average (4.1% of 146,066 US applicants). Thirty of the 100 surveyed Cambridge Integrated Clerkship graduates (30%) responded to the qualitative survey with free-text remarks on a number of themes. Cambridge Integrated Clerkship students compared positively to their classmates in terms of standardized test performance. Their fourfold higher match rate into psychiatry compared to other students raises intriguing questions as to what role a longitudinal clerkship might have played in developing interest in psychiatry as a career.

    The integration of electronic devices into clothing to monitor biosignals is demonstrated with the integration of a 3-channel ECG device into a shirt. It is shown that several basic requirements concerning the electronic design must be fulfilled, exceeding the capabilities of conventional portable systems. The application of flexible connection and housing technologies is addressed in the present paper. Printed boards should be flexible enough to adapt to movements of the human body. Small size as well as water-resistant or even washable construction is required. Additional points concern replacing the disturbing loose cable connections with a more integrated solution. A long period of operation without recharging the battery, uploading the data or changing the electrodes has to be achieved. The system should feature an uninterrupted 7-day operation period known as 24/7-monitoring regime. Starting with its specification, the basic design of the prototype is presented. First investigations have shown the washability of the shirt together with the inserted electronics.

    Full Text Available In this article we discuss the results of surgical treatment in patients with different acquired heart diseases. Procedures ranged from valve reconstruction, coronary artery revascularization, surgical repair or graft repair of the thoracic aorta to hybrid surgery in patients with combined acquired heart valve diseases and coronary artery diseases. The implementation of biological grafts for aortic repair in 147 cases was successfully performed with low in-hospital mortality (9.8%. Hybrid procedures in patients older than 70 years allowed reducing hospital mortality rate in 3 times in comparison with the standard surgery: 4% vs. 12%, respectively. We developed and introduced into clinical practice the original protocol for patients with aortal valve disease and low left ventricularejection fraction (mean – 24.3%. Due to this protocol 46 procedures were performed, in-hospital mortality was 4.4%. Cardiac surgery in patients on dialysis is one of the priorities in our practice. Our experience demonstrates that short waiting time of kidney transplantation after heart valve replacement improves long-term outcomes.

    One feature of a smart structure implies that some computational and signal processing capability can be performed at a local level, perhaps integral to the controlled structure. This requires electronics with a minimal mechanical influence regarding structural stiffening, heat dissipation, weight, and electrical interface connectivity. The Advanced Controls Technology Experiment II (ACTEX II) space-flight experiments implemented such a local control electronics scheme by utilizing composite smart members with integral processing electronics. These microelectronics, tested to MIL-STD-883B levels, were fabricated with conventional thick film on ceramic multichip module techniques. Kovar housings and aluminum-kapton multilayer insulation was used to protect against harsh space radiation and thermal environments. Development and acceptance testing showed the electronics design was extremely robust, operating in vacuum and at temperature range with minimal gain variations occurring just above room temperatures. Four electronics modules, used for the flight hardware configuration, were connected by a RS-485 2 Mbit per second serial data bus. The data bus was controlled by Actel field programmable gate arrays arranged in a single master, four slave configuration. An Intel 80C196KD microprocessor was chosen as the digital compensator in each controller. It was used to apply a series of selectable biquad filters, implemented via Delta Transforms. Instability in any compensator was expected to appear as large amplitude oscillations in the deployed structure. Thus, over-vibration detection circuitry with automatic output isolation was incorporated into the design. This was not used however, since during experiment integration and test, intentionally induced compensator instabilities resulted in benign mechanical oscillation symptoms. Not too surprisingly, it was determined that instabilities were most detectable by large temperature increases in the electronics, typically

    2005-01-01

    Today's NASA is facing significant challenges and changes. The Exploration initiative indicates a large increase in projects with limited increase in budget. The Columbia report has criticized NASA for its lack of insight and technical integration impacting its ability to provide safety. The Aldridge report is advocating NASA find new ways of doing business. Very early in the Space Launch Initiative (SLI) program a small team of engineers at MSFC were asked to propose a process for performing a system level assessment of a launch vehicle. The request was aimed primarily at providing insight and making NASA a "smart buyer." Out of this effort the VIPA team was created. The difference between the VIPA effort and many integration attempts is that VIPA focuses on using experienced people from various disciplines and a process which focuses them on a technically integrated assessment. Most previous attempts have focused on developing an all encompassing software tool. In addition, VIPA anchored its process formulation in the experience of its members and in early developmental Space Shuttle experience. The primary reference for this is NASA-TP-2001-210092, "Launch Vehicle Design Process: Characterization, Technical Integration, and Lessons Learned," and discussions with its authors. The foundations of VIPA's process are described. The VIPA team also recognized the need to drive detailed analysis earlier in the design process. Analyses and techniques typically done in later design phases, are brought forward using improved computing technology. The intent is to allow the identification of significant sensitivities, trades, and design issues much earlier in the program. This process is driven by the T-model for Technical Integration described in the aforementioned reference. VIPA's approach to performing system level technical integration is discussed in detail. Proposed definitions are offered to clarify this discussion and the general systems integration dialog. VIPA

    Here, integrated fast ignition experiments were performed at ILE, Osaka, and LLE, Rochester, in which a nanosecond driver laser implodes a deuterated plastic shell in front of the tip of a hollow metal cone and an intense ultrashort-pulse laser is injected through the cone to heat the compressed plasma. Based on the initial successful results of fast electron heating of cone-in-shell targets, large-energy short-pulse laser beam lines were constructed and became operational: OMEGA-EP at Rochester and LFEX at Osaka. Neutron enhancement due to heating with a ~kJ short-pulse laser has been demonstrated in the integrated experiments at Osaka and Rochester. The neutron yields are being analyzed by comparing the experimental results with simulations. Details of the fast electron beam transport and the electron energy deposition in the imploded fuel plasma are complicated and further studies are imperative. The hydrodynamics of the implosion was studied including the interaction of the imploded core plasma with the cone tip. Theory and simulation studies are presented on the hydrodynamics of a high-gain target for a fast ignition point design.

    Demonstrated interactions between seeing and hearing led us to assess the link between music training and short-term memory for auditory, visual and audiovisual sequences of rapidly presented, quasi-random components. Visual sequences' components varied in luminance; auditory sequences' components varied in frequency. Concurrent components in audiovisual sequences were either congruent (the frequency of an auditory item increased monotonically with the luminance of the visual item it accompanied), or incongruent (an item's frequency was uncorrelated with luminance of the item it accompanied). Subjects judged whether the last four items in a sequence replicated its first four items. With audiovisual sequences, subjects were instructed to ignore the sequence's auditory components, basing their judgments solely on the visual input. Subjects with prior instrumental training significantly outperformed their untrained counterparts, with both auditory and visual sequences, and with sequences of correlated auditory and visual items. Reverse correlation showed that the presence of a correlated, concurrent auditory stream altered subjects' reliance on particular visual items in a sequence. Moreover, congruence between auditory and visual items produced performance above what would be predicted from simple summation of information from the two modalities, a result that might reflect a contribution from special-purpose, multimodal neural mechanisms.

    While fathers are increasingly expected to participate during their partners' pregnancies and childbirth and many studies have reported their experiences during these periods, no review studies have examined fathers' experiences and needs during pregnancy and childbirth together. To provide an overview of evidence on fathers' experiences and needs during their partners' pregnancies and childbirth to identify any gaps in the existing literature and practice. An integrative literature review was performed to analyse and synthesize fathers' experiences and/or needs during pregnancy and/or childbirth based on articles published in CINAHL, PubMed, Scopus, PsycINFO and Web of Science databases between the years 2002 and 2012. Only articles found in the National University of Singapore's online library collection were retrieved. Altogether, 25 studies (six quantitative and 19 qualitative studies) that reported fathers' experiences during pregnancy (n = 8), childbirth (n = 13) or during both periods (n = 4) were reviewed. Fathers experienced mixed feelings both during pregnancy and childbirth. They required support from their partners and healthcare professionals and wanted to be informed, involved and respected. However, more studies are needed to explore this phenomenon in different cultural contexts or care models. This review provides evidence for healthcare professionals to pay more attention to fathers when delivering perinatal care. Sociocultural-sensitive interventions should be developed to facilitate a smoother transition to fatherhood. Father-specific information should be given to prepare fathers for pregnancy and childbirth. Healthcare professionals and policymakers should take fathers' feelings and concerns into consideration and provide family-centred care to the couple during the antenatal and intrapartum periods. © 2014 International Council of Nurses.

    2017-02-01

    To explore patients' perspectives on care received from diabetes education teams (a registered nurse and a registered dietitian) integrated into primary care. Qualitative study using semistructured, one-on-one interviews. Three diabetes education programs operating in 11 primary care sites in one region of Ontario. Twenty-three patients with diabetes. Purposeful sampling was used to recruit participants from each site for interviews. Educator teams invited patients with whom they had met at least once to participate in semistructured interviews. Data were analyzed using thematic analysis with NVivo 11 software. The diabetes education teams integrated into primary care exhibited many of the principles of person-centred care, as evidenced by the 2 overarching themes. The first is personalized care, with the subthemes care environment, shared decision making, and patient preference for one-on-one care. Participants described feeling included in partnerships with their health care providers, as they collaborated with physicians and diabetes educators to develop knowledge and set goals in the convenience and comfort of their usual primary care settings. Many participants also expressed a preference for one-on-one sessions. The second theme is patient-provider relationship, with the subthemes respect, supportive interaction, and facilitating patient engagement. Supportive environments created by the educators built trusting relationships, where patients expressed enhanced motivation to improve their self-care. Diabetes educators integrated into primary care can serve to enrich the experience of patients, provide key education to improve patient understanding, and support primary care physicians in providing timely and comprehensive clinical care. Diabetes patients appear to benefit from convenient access to interprofessional teams of educators in primary care to support diabetes self-management.

    The main objective of the research 'Zero Emission Buildings' ZEB is to develop products and solutions that provide buildings with zero greenhouse gas emissions associated with the production, operation and disposal. Can we make this happen must the building produce more energy than it needs to compensate for greenhouse gas emissions from the production of materials and the actual construction.To build up knowledge on experience with building integrated solar collectors in Norway, we have in this study made interviews with suppliers and manufacturers of solar collectors and some building owners. Since the focus is on climate shell, we have limited the study to include solar collectors to replace a part of the cladding or roofing. Construction upstairs roofing, outside facade or freestanding rack is not considered as building integrated in this context. The providers we have been in contact with appeals to slightly different parts of the market. This is reflected in the product's development, assembly and approach to the calculation of energy delivery. Overall, providers may offer a range of products suitable for both the professional and skilled carpenter, the interested 'man in the street' . The feedback we have received shows generally good experiences with the product and the installation. Because of the preliminary short operating periods of the investigated plants we have little data on energy supply from these plants. In summary, we can say that the knowledge and the products are available and it is up to use to use them.(Author)

    Saudi Aramco pipelines network transports hydrocarbons to export terminals, processing plants and domestic users. This network faced several safety and operational-related challenges that require having a more effective Pipelines Integrity Management System (PIMS). Therefore Saudi Aramco decided to develop its PIMS on the basis of geographical information system (GIS) support through different phases, i.e., establishing the integrity management framework, risk calculation approach, conducting a gap analysis toward the envisioned PIMS, establishing the required scope of work, screening the PIMS applications market, and selecting suitable tools that satisfy expected deliverables, and implement PIMS applications. Saudi Aramco expects great benefits from implementing PIMS, e.g., enhancing safety, enhancing pipeline network robustness, optimizing inspection and maintenance expenditures, and facilitating pipeline management and the decision-making process. Saudi Aramco's new experience in adopting PIMS includes many challenges and lessons-learned associated with all of the PIMS development phases. These challenges include performing the gap analysis, conducting QA/QC sensitivity analysis for the acquired data, establishing the scope of work, selecting the appropriate applications and implementing PIMS.

  9. From Differentiation to Concretisation: Integrative Experiments in Sustainable Architecture

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available It is widely recognised that the achievement of a sustainable built environment requires holistic design practices and approaches that are capable of balancing the varied, and often conflicting, demands of environmental, social and economic concerns. However, academics and practitioners have recently highlighted, and expressed concerns about the knowledge gap that currently exists within environmental policy, research and practice between understandings of the technical performance of buildings and their social meaning and relevance. This paper acknowledges these concerns and is developed from the author’s own direct experiences of practice-led research and active participation in design-build projects. It argues for a theoretically-informed and socially-engaged approach to built environment research, pedagogy and practice that seeks to encourage an integrative understanding of the design, realisation and use of sustainable architecture. The paper draws on the Philosophy of Technology and in particular the work of Andrew Feenberg to analyse the buildings and to propose an integrated and inclusive framework for understanding sustainable design that acknowledges not just what the built environment does, but also what it means. It also suggests that what a building means also informs what it can do, and for whom. Although the technical and social dimensions of design can be interpreted as distinct practices and are often institutionally separated, this paper argues that the realisation of sustainable design must seek a conscious interaction and interchange between these two differentiated dimensions.

  13. Neuroplasticity beyond Sounds: Neural Adaptations Following Long-Term Musical Aesthetic Experiences

    Directory of Open Access Journals (Sweden)

    Mark Reybrouck

    2015-03-01

    Full Text Available Capitalizing from neuroscience knowledge on how individuals are affected by the sound environment, we propose to adopt a cybernetic and ecological point of view on the musical aesthetic experience, which includes subprocesses, such as feature extraction and integration, early affective reactions and motor actions, style mastering and conceptualization, emotion and proprioception, evaluation and preference. In this perspective, the role of the listener/composer/performer is seen as that of an active “agent” coping in highly individual ways with the sounds. The findings concerning the neural adaptations in musicians, following long-term exposure to music, are then reviewed by keeping in mind the distinct subprocesses of a musical aesthetic experience. We conclude that these neural adaptations can be conceived of as the immediate and lifelong interactions with multisensorial stimuli (having a predominant auditory component, which result in lasting changes of the internal state of the “agent”. In a continuous loop, these changes affect, in turn, the subprocesses involved in a musical aesthetic experience, towards the final goal of achieving better perceptual, motor and proprioceptive responses to the immediate demands of the sounding environment. The resulting neural adaptations in musicians closely depend on the duration of the interactions, the starting age, the involvement of attention, the amount of motor practice and the musical genre played.

Our students are engaged into a field trip where mining occurs to start the problem based learning of how the heavy metals leak in the mining process. These heavy metals such as lead and indium in the groundwater are a serious concern for the environment (Environmental Protection Agency from the mining process. The field experiences at the mining process assist in building our students interest in developing sensors to detect heavy metals of concern such as lead and indium simultaneously by a unique electrochemistry technique called Square Wave Anodic Stripping Voltammetry (SWASV. The field experience assists building the students interest in real –world application and what qualities do they want the electrochemical sensor to possess to be successful for real world usage. During the field trip the students are engaged into learning novel instrumentation such as an SEM (Scanning Electron Microscope to study the working electrode sensor developed to understand the sensor surface morphology properties better as well. The integration of industry setting with academia has been a positive experience for our students that has allowed their understanding of real-world science research needs to succeed in an industrial setting of research.

    This study examined associations between adverse childhood family experiences and adult physical health using data from 52,250 US adults aged 18–64 from the 2009–2012 Behavioral Risk Factor Surveillance System (BRFSS). We found that experiencing childhood physical, verbal, or sexual abuse, witnessing parental domestic violence, experiencing parental divorce, and living with someone who was depressed, abused drugs or alcohol, or who had been incarcerated were associated with one or more of the following health outcomes: self-rated health, functional limitations, diabetes, and heart attack. Adult socioeconomic status and poor mental health and health behaviors significantly mediated several of these associations. The results of this study highlight the importance of family-based adverse childhood experiences on adult health outcomes and suggest that adult SES and stress-related coping behaviors may be crucial links between trauma in the childhood home and adult health.

    To understand the work-related experiences of Philippine-trained nurses working globally. The Philippines is a major source country of foreign-trained nurses located globally. However, there is paucity of research on professional factors and career related issues affecting foreign-trained nurses' work experiences. An integrative review through a comprehensive search of literature was undertaken from November 2015 and was repeated in August 2016. Seven articles satisfied the selection criteria. Filipino nurses experienced differences in the practice of nursing in terms of work process, roles and autonomy. Moreover, they encountered challenges such as work-related discrimination and technical difficulties within the organisation. A clear understanding of Filipino nurses' work experiences and the challenges they have encountered suggests identification of important constructs influencing effective translation of nursing practice across cultures and health systems, which then form the basis for support strategies. It is critical to recognize foreign-trained nurses' experience of work-related differences and challenges as these foster favorable conditions for the management team to plan and continually evaluate policies around recruitment, retention and support offered to these nurses. Furthermore, findings suggest internationalization of nursing framework and standards integrating a transcultural paradigm among staff members within a work organisation. © 2017 John Wiley & Sons Ltd.

    AAE 451 is the capstone course required of all senior undergraduates in the School of Aeronautics and Astronautics at Purdue University. During the past year the first steps of a long evolutionary process were taken to change the content and expectations of this course. These changes are the result of the availability of advanced computational capabilities and sophisticated electronic media availability at Purdue. This presentation will describe both the long range objectives and this year's experience using the High Speed Commercial Transport design, the AIAA Long Duration Aircraft design and RPV design proposal as project objectives. The central goal of these efforts is to provide a user-friendly, computer-software-based environment to supplement traditional design course methodology. The Purdue University Computer Center (PUCC), the Engineering Computer Network (ECN) and stand-alone PC's are being used for this development. This year's accomplishments center primarily on aerodynamics software obtained from NASA/Langley and its integration into the classroom. Word processor capability for oral and written work and computer graphics were also blended into the course. A total of ten HSCT designs were generated, ranging from twin-fuselage aircraft, forward swept wing aircraft to the more traditional delta and double-delta wing aircraft. Four Long Duration Aircraft designs were submitted, together with one RPV design tailored for photographic surveillance.

    Full Text Available The purpose of the paper is to determine threats and benefits of exchange rate regimes in terms of the integration of Ukraine into the European community. Emphasizing features of the manifestation of currency exchange rate in Ukrainian practice is a precondition for choosing the optimal exchange rate regime for Ukraine, which, in its turn, will provide an opportunity to reduce inflation and implement effective tools of monetary and fiscal policies to promote further economic growth and competitiveness of the country. The uses of free-floating exchange rate and «currency board» regimes have either positive effects for Ukraine or certain threats. Methodology. This research is based on a synthesis of data on the uses of exchange rate regimes in Ukraine as an independent. It is considered angular regimes, which are by far the most suitable for Ukraine in terms of the European vector of its development. Peculiarities of using these regimes are revealed and their major threats to the domestic economy are pointed out. This article analyzes the dynamics of the trade balance of payments of Ukraine, the dynamics of the commodity structure of Ukraine`s exports and imports and the external debt of Ukraine. Results. Taking into account the experience of countries, which were in crisis situations, they show the necessity of the uses of freefloating exchange rate regime and possibilities of «currency board» regime, despite threats that they may have. World experience testifies the implementation of structural reforms, effective monetary policy, fiscal policy and discipline of the government. Thorough preparation of Ukraine’s transition to the «currency board» regime can justify itself in conditions of crisis and provide impetus to Ukrainian economy benefits. The paper defines conditions under which the success of a new model of exchange rate policy will be achieved. Practical implications. The study accents attention on the specifics of the uses of the

    Increased global temperatures, altered rainfall patterns and frequently occurring extreme climatic events are already observed globally as a result of the climatic changes and further increases are predicted by the climatic models. Extreme weather events such as prolonged dry spells and heat waves can significantly affect soil ecosystem functions mainly due to decrease in soil moisture. Several studies suggested an increase in soil water repellency severity and spread as a consequence of the warming and drought, however, such understanding is based on the laboratory experimentations with soil treated as a 'black box'. In this study we tested the hypothesis of increased severity of soil water repellency subjected to drought and warming under field conditions. Occurrence and severity of soil water repellency was tested in soils subjected to a long-term (10 years) climatic simulation at two upland heathland sites in Oldebroek (Netherlands) and in Clocaenog (UK)[1]. Soil plots with similar vegetation were subjected to repeated drought and warming, compared with the control plots. Drought effect was created by a rainfall exclusion using an automatic self-retracting waterproof curtains while the warming effect was made by using a self-retracting curtains reflecting infrared radiation overnight. The results available to date provide a strong indication that climatic conditions do affect the development of SWR.

  10. Integrating Permafrost into an Earth System Model: First Sensitivity Experiments

    2010-05-01

    Approximately one-fifth of the Northern Hemisphere's land surface is underlain by permafrost. Yet, to date, few global climate models have incorporated freeze/thaw soil processes and permafrost evolution into their simulations. This may be a significant component to omit since it has been well-established that like many parts of the Arctic system, permafrost is responding to a warming climate. As been observed at many sites around the circumpolar arctic, subarctic, and alpine locations, this includes warming soil temperatures, decreasing permafrost extent, and thickening active layer. Not only do freezing and thawing processes play a significant role in the land surface energy and moisture balance but such changes imply potential feedback effects as well. Specifically, changes in the permafrost regime can feedback to the climate system via three mechanisms: 1) as a source/sink of thermal energy through latent heat exchange, 2) as a regulator of regional hydrology, and 3) as a carbon reservoir. The best way to analyze these feedback effects, and hence the overall role of permafrost within the earth system, is to incorporate surface and subsurface freeze/thaw processes within a climate model. Therefore, as impetus to narrow this research gap, our project will be enhancing an existing earth system model of intermediate complexity called LOVECLIM by integrating a frozen soil algorithm within the land surface component. An examination of the permafrost-climate relationship will be done at both present climate and the last glacial maximum climate. We specifically focus at paleoclimate time scales that allow the simulations to capture the slow response time (relative to other earth system components) of permafrost and allow changes in permafrost and associated functions to feedback to the climate. However, before coupling to LOVECLIM, we first performed sensitivity experiments on the algorithm to determine the parameterization most fitting for the research scope. This

  11. Towards a long-term integrated monitoring programme in Europe: network design in theory and practice.

    2002-09-01

    Long-term integrated monitoring is an important approach for investigating, detecting and predicing the effects of environmental changes. Currently. European freshwaters, glaciers, forests and other natural and semi-natural ecosystems and habitats are monitored by a number of networks established by different organisations. However, many monitoring programmes have a narrow focus (e.g. targeting individual ecosystems) and most have different measurement protocols and sampling design. This has resulted in poor integration of ecosystem monitoring at a European level, leading to some overlapping of efforts and a lack of harmonised data to inform policy decisions. The need for a consistent pan-European long-term integrated monitoring of terrestrial systems programme is recognised in the scientific community. However, the design of such a system can be problematic, not least because of the constraints imposed by the need to make maximum use of existing sites and networks. Based on the outcomes of the NoLIMITS project (Networking of Long-term Integrated Monitoring in Terrestrial Systems). this article reviews issues that should be addressed in designing a programme based on existing monitoring sites and networks. Four major design issues are considered: (i) users' requirements, (ii) the need to address multiple objectives, (iii) role of existing sites and (iv) operational aspects.

  12. Directions of Development of International Production Specialization Theory in Terms of Integration

    Full Text Available The article is devoted to the definition of directions of development of the theory of international production specialization in terms of integration based on new trends in various areas of international business. The author proposes a new concept of international industrial specialization in terms of integration. As a result of research the author came to the conclusion that in the current economic conditions the need for a free market constraints associated with the deepening global market failures is becoming more and more obvious. Therefore, in the process of international specialization of production in the conditions of integration of the country should be guided not by comparative advantage in the production of certain goods or services, but also by other criteria. These criteria are: financial criterion determining the financial situation in the country, the trade criterion, reflecting the possibility of benefiting from international trade, technological criterion, considering the technological security of the country in the field of specialization and the cyclical criterion, reflecting the situation in the world economy and the level of integration of the country. On the basis of these criteria, the author identifies three categories of countries according to their ability to benefit from an international industrial specialization in the integration process: effective export, export-neutral and export-inefficient countries.

    The long-term impacts of climate conditions on soil ecosystems are difficult to discern with sufficient resolution to underpin a predictive understanding of ecosystem response to global climate change. The structure and function of the microbial community is intimately linked to soil organic carbon (SOC) by both the deposition of new carbon, and metabolism and respiration of existing SOC. We are studying the resilience of the microbial community, and the vulnerability of the soil carbon reservoirs, to changing climate conditions using a reciprocal soil transplant experiment initiated in 1994 in eastern Washington. Soil cores were reciprocally transplanted between two elevations (310 m and 844 m); the lower site is warmer and drier with 0.8% soil carbon, and the upper site is cooler and wetter with 1.8% soil carbon. We resampled these cores in 2012-13 to analyze the structure of the microbial community, biochemical activities of carbohydrate-active enzymes, and the soil carbon and nitrogen content. We hypothesized that microbial and biochemical dynamics developed under cool, moist conditions would destabilize under hot, dry conditions, such that carbon and nitrogen losses would be faster in warmer climate soils than the accruals in cooler climate soils. Metagenomics data analyses show that the microbial communities below 5 cm depth in the transplanted soils are most similar to those in the native and control soils from their original (pre-1994) location, whereas the surface microbial community has been influenced by their new (post-1994) location. Enzyme activities are highest in soils from the cooler, moister location, and the activities of the reciprocally transplanted soils are shifting toward the activities typical of their new location. Integration of these results with high-resolution mass spectrometry data of the soil carbon moieties will contribute to our fundamental understanding of climate change effects on the terrestrial ecosystem carbon cycle.

  14. An integrative view of storage of low- and high-level visual dimensions in visual short-term memory.

    Efficient performance in an environment filled with complex objects is often achieved through the temporal maintenance of conjunctions of features from multiple dimensions. The most striking finding in the study of binding in visual short-term memory (VSTM) is equal memory performance for single features and for integrated multi-feature objects, a finding that has been central to several theories of VSTM. Nevertheless, research on binding in VSTM focused almost exclusively on low-level features, and little is known about how items from low- and high-level visual dimensions (e.g., colored manmade objects) are maintained simultaneously in VSTM. The present study tested memory for combinations of low-level features and high-level representations. In agreement with previous findings, Experiments 1 and 2 showed decrements in memory performance when non-integrated low- and high-level stimuli were maintained simultaneously compared to maintaining each dimension in isolation. However, contrary to previous findings the results of Experiments 3 and 4 showed decrements in memory performance even when integrated objects of low- and high-level stimuli were maintained in memory, compared to maintaining single-dimension objects. Overall, the results demonstrate that low- and high-level visual dimensions compete for the same limited memory capacity, and offer a more comprehensive view of VSTM.

    Program performance of the Malaysian Felda program, an integrated population development program, is examined in this report. It also evaluates the relationship of the performance of this program with its organizational, integrational, and community support factors. Starting in 1956, Felda had, by the end of 1981, developed 308 land schemes covering an area of 1.4 million acres planted predominantly with oil palm (59.4%) and rubber (31.6%). The land schemes have settled a total of 70,600 families or over 400,000 people. The integrated programs existing in the Felda schmes are the focus of analysis for this study. Out of the universe of 308 Felda schemes, 26 schemes were randomly selected for the study. In each scheme, 2 surveys were conducted: first, the staff surveys to gather information on the organizational factors and extent of integration in existence in the scheme and then household surveys to gather information on the extent of community support for the integrated program and the performance of the program. In the case of the performance variables, the information gathered from the household survey was supplemented by the records from the Felda scheme office. In the sample of 26 schemes, a total of 1641 settler households were selected for the household survey and 363 staff were selected for the staff survey. The surveys were conducted in the 1st quarter of 1982. The results indicate that the Felda mode of delivering population and community development services has been very effective. Over 55.2% of the eligible women were found to be practicing family planning (compared to about 35.5% for the national rural average), while over 78.9% of the eligible women utilized postnatal health care facilities. About 1 in 3 of the eligible children in Felda schemes attend kindergarten classes, while over 46.9% of the Felda households are involved in some form of extramural income generating activities. The more integrated the program in a particular community, the more

    2004-01-01

    Vertical integration of medical education is currently a prominent international topic, resulting from recent strategic initiatives to improve medical education and service delivery in areas of poorly met medical need. In this article, vertical integration of medical education is defined as 'a grouping of curricular content and delivery mechanisms, traversing the traditional boundaries of undergraduate, postgraduate and continuing medical education, with the intent of enhancing the transfer of knowledge and skills between those involved in the learning-teaching process'. Educators closely involved with vertically integrated teaching in the Riverland of South Australia present an analytical description of the educational dynamics of this system. From this analysis, five elements are identified which underpin the process of successful vertical integration: (1) raised educational stakes; (2) local ownership; (3) broad university role; (4) longer attachments; and (5) shared workforce vision. Given the benefits to the Riverland medical education programs described in this paper, it is not surprising that vertical integration of medical education is a popular goal in many rural regions throughout the world. Although different contexts will result in different functional arrangements, it could be argued that the five principles outlined in this article can be applied in any region.

    The article discusses the desirability of integrated project management systems within the French nuclear power industry. Change in demand for nuclear generation facilities over the last two decades has necessitated a change of policy concerning organization, cost and planning within the industry. Large corporate systems can benefit from integrating equipment and bulk materials tracking. Project management for the nuclear industry will, in future, need to incorporate computer aided design tools and project management information systems data bases as well as equipment and planning data.

    Full Text Available Adoption of management systems standards is a key issue in manufacturing industry in India. Following the global trend quality and environmental issues are gaining importance. However the number of ISO 14001 certified companies are much less in India as compared to ISO 9001. The integration of ISO 14001 with ISO 9001 may help companies to sustain competitive advantage and overcome disappointments with quality standards and in turn encourage companies to adopt good environmental practices. The aim of this research is to study the implementation of integrated management standards (IMS by the manufacturing organizations in India. The different aspects of integration and benefits of IMS implementation are analyzed. This r esearch is based on empirical study carried out in Indian manufacturing firms, involving the application of a questionnaire. This questionnaire was tested on 50 manufacturing companies in India. The study reveals that focus on stakeholders; top management commitment and training are critical success factors for implementation of IMS. The main benefits of integration are discussed. The small sample size is one of the major limitations of this study. The paper informs the managers in manufacturing organizations and practitioners of management system standards especially in developing countries about IMS and will enable them to adopt IMS in future so that those organizations may not implement multiple and overlapping MSS(Management System Standards.

    Full Text Available Stabilized voltage sources, even linear or working on a switching principle, are an integral part of almost all electronic devices. Hand in hand with the pressure of environmental protection, there comes an emphasis on reducing energy consumption, resulting in preference of switching solutions. On the other hand, considering the issues on electromagnetic compatibility, each switching-mode operated power source produces considerable amount of interferences. In the framework of the hereby described experiment, the authors of the paper tested several voltage sources operating on the switching principle. This paper provides a description of the experiment and the obtained results.

  4. A Literature Review on the Experience of Long-Term Mental Illness.

    2018-02-13

    To illuminate long-term experiences of mental illness from both research and autobiographical accounts. A literature review of English-language papers, 1950-2014, relating to the experience of long-term mental illness indexed in AgeInfo, AMED, ASSIA, British Nursing Index (BNI), CINAHL, MEDLINE, PsycEXTRA, and PsychINFO. Twenty-five research papers and nine autobiographic accounts met the review criteria. Thematic analysis revealed nine themes: fear, explanation seeking, stigma, disability, coping strategies, control, support, change and learning, and life history. Specific gaps of note relate to age differences, acknowledgement of longevity of mental illnesses, and different cultural perspectives. Research Implications: There is an absence of longitudinal studies focused on experiences of long-term mental illness. The considerable length-of-time implicated in the experiences suggests that more individual life experience rather than illness focused studies are needed, enabling a holistic understanding. This includes studies from cultures other than the Western world. Greater transparency is needed in justifying age inclusions or passive exclusion of older peoples' perspectives. Knowledge of long-term mental illness experiences is of great importance to mental health practitioners. Evidence-based services cannot be provided if we do not have an holistic understanding of long-term mental illness. Social Implications: This review questions our ability to provide effective support for those experiencing long-term mental illness, in particular older people and different cultural perspectives. There appear to be no literature reviews that focus on the individual experience of long-term mental illness. It highlights the surprisingly small number of research studies available to inform mental health practitioners.

    Here we present an application, in two tumour cell lines, based on the Sensing Cell Culture Flask system as a cell culture monitoring tool for pericellular oxygen sensing. T-47D (human breast cancer) and T98G (human brain cancer) cells were cultured either in atmospheric air or in a glove-box set at 4% oxygen, in both cases with 5% CO2 in the gas phase. Pericellular oxygen tension was measured with the help of an integrated sensor chip comprising oxygen sensor arrays. Obtained results illustrate variation of pericellular oxygen tension in attached cells covered by stagnant medium. Independent of incubation conditions, low pericellular oxygen concentration levels, usually associated with hypoxia, were found in dense cell cultures. Respiration alone brought pericellular oxygen concentration down to levels which could activate hypoxia-sensing regulatory processes in cultures believed to be aerobic. Cells in culture believed to experience conditions of mild hypoxia may, in reality, experience severe hypoxia. This would lead to incorrect assumptions and suggests that pericellular oxygen concentration readings are of great importance to obtain reproducible results when dealing with hypoxic and normoxic (aerobic) incubation conditions. The Sensing Cell Culture Flask system allows continuous monitoring of pericellular oxygen concentration with outstanding long-term stability and no need for recalibration during cell culture experiments. The sensor is integrated into the flask bottom, thus in direct contact with attached cells. No additional equipment needs to be inserted into the flask during culturing. Transparency of the electrochemical sensor chip allows optical inspection of cells attached on top of the sensor. © 2014 John Wiley & Sons Ltd.

    2017-09-01

    The aim of this study was to explore students' reflective thinking about long-term care experiences from the perspective of a model of oral health. A total of 186 reflections from 193 second-year undergraduate dental students enrolled between 2011/12 and 2014/15 at the University of British Columbia were explored qualitatively. Reflections had a word limit of 300, and students were asked to relate an existing model of oral health to their long-term care experiences. We have identified the main ideas via a thematic analysis related to the geriatric dentistry experience in long-term care. The thematic analysis revealed that students attempted to demystify their pre-conceived ideas about older people and long-term care facilities, to think outside the box, for example away from a typical dental office, and to consider caring for elderly people from an interprofessional lens. According to some students, not all domains from the existing model of oral health were directly relevant to their geriatric experience while other domains, including interprofessionalism and cognition, were missing. While some participants had a positive attitude towards caring for this cohort of the population, others did not take this educational activity as a constructive experience. The nature of most students' reflective thinking within a long-term care experience showed to be related to an existing model of oral health. This model can help to give meaning to the dental geriatric experience of an undergraduate curriculum. Such experience has been instrumental in overcoming potential misconceptions about long-term care and geriatric dentistry. © 2017 John Wiley & Sons A/S and The Gerodontology Association.

  9. Integration of microbial biopesticides in greenhouse floriculture: The Canadian experience.

    Brownbridge, Michael; Buitenhuis, Rose

    2017-11-28

    Historically, greenhouse floriculture has relied on synthetic insecticides to meet its pest control needs. But, growers are increasingly faced with the loss or failure of synthetic chemical pesticides, declining access to new chemistries, stricter environmental/health and safety regulations, and the need to produce plants in a manner that meets the 'sustainability' demands of a consumer driven market. In Canada, reports of thrips resistance to spinosad (Success™) within 6-12 months of its registration prompted a radical change in pest management philosophy and approach. Faced with a lack of registered chemical alternatives, growers turned to biological control out of necessity. Biological control now forms the foundation for pest management programs in Canadian floriculture greenhouses. Success in a biocontrol program is rarely achieved through the use of a single agent, though. Rather, it is realized through the concurrent use of biological, cultural and other strategies within an integrated plant production system. Microbial insecticides can play a critical supporting role in biologically-based integrated pest management (IPM) programs. They have unique modes of action and are active against a range of challenging pests. As commercial microbial insecticides have come to market, research to generate efficacy data has assisted their registration in Canada, and the development and adaptation of integrated programs has promoted uptake by floriculture growers. This review documents some of the work done to integrate microbial insecticides into chrysanthemum and poinsettia production systems, outlines current use practices, and identifies opportunities to improve efficacy in Canadian floriculture crops.

    Intel recently released the first commercial boards of its Many Integrated Core (MIC) Architecture. MIC is Intel's solution for the domain of throughput computing, currently dominated by general purpose programming on graphics processors (GPGPU). MIC allows the use of the more familiar x86 programming model and supports standard technologies such as OpenMP, MPI, and Intel's Threading Building Blocks. This should make it possible to develop for both throughput and latency devices using a single code base.\

    The first 2 integrated vascular residents in the United States graduated in 2012, and in 2013, 11 more entered the job market. The purpose of this study was to compare the job search experiences of the first cohort of integrated 0 + 5 graduates to their counterparts completing traditional 5 + 2 fellowship programs. An anonymous, Web-based, 15-question survey was sent to all 11 graduating integrated residents in 2013 and to the 25 corresponding 5 + 2 graduating fellows within the same institution. Questions focused on the following domains: training experience, job search timelines and outcomes, and overall satisfaction with each training paradigm. Survey response was nearly 81% for the 0 + 5 graduates and 64% for the 5 + 2 graduates. Overall, there was no significant difference between residents and fellows in the operative experience obtained as measured by the number of open and endovascular cases logged. Dedicated research time during the entire training period was similar between residents and fellows. Nearly all graduates were extremely satisfied with their training and had positive experiences during their job searches with respect to starting salaries, numbers of offers, and desired practice type. More 0 + 5 residents chose academic and mixed practices over private practices compared with 5 + 2 fellowship graduates. Although longer term data are needed to understand the impact of the addition of 0 + 5 graduating residents to the vascular surgery work force, preliminary survey results suggest that both training paradigms (0 + 5 and 5 + 2) provide positive training experiences that result in excellent job search experiences. Based on the current and future need for vascular surgeons in the work force, the continued growth and expansion of integrated 0 + 5 vascular surgery residency positions as an alternative to traditional fellowship training is thus far justified.

    Sensorimotor integration is impaired in patients with Parkinson's disease (PD). Short latency afferent inhibition (SAI) and long latency afferent inhibition (LAI) measured with transcranial magnetic stimulation (TMS) can be used to measure sensorimotor integration. Subthalamic nucleus (STN) deep brain stimulation (DBS) has been found to restore these abnormalities, but the time course of these changes is not known. We prospectively evaluated the short-term and long-term effects of STN DBS on SAI, LAI and proprioception. We hypothesised plasticity changes induced by chronic stimulation are necessary to normalise sensorimotor integration and proprioception. Patients with PD were studied preoperatively, at 1 month and more than 6 months postoperatively. SAI was tested with median nerve stimulation to the wrist preceding TMS pulse to motor cortex by ~20 ms and LAI by 200 ms. Proprioception (distance and spatial errors) in the arm was quantitatively assessed. For postoperative assessments, patients were studied in the medication-off/stimulator-off, medication-off/stimulator-on, medication-on/stimulator-off and medication-on/stimulator-on conditions. 11 patients with PD and 10 controls were enrolled. Preoperatively, SAI and proprioception was abnormal during the medication-on conditions and LAI was reduced regardless of the medication status. STN DBS had no significant effect on SAI, LAI and proprioception at 1 month. However, at 6 months SAI, LAI and distance errors were normalised in the medication-on/stimulator-on condition. Spatial error was normalised with DBS on and off. Chronic STN DBS in PD normalises sensorimotor integration and proprioception, likely through long-term plastic changes in the basal ganglia thalamocortical circuit.

    The human ability to integrate the input of several sensory systems is essential for building a meaningful interpretation out of the complexity of the environment. Training studies have shown that the involvement of multiple senses during training enhances neuroplasticity, but it is not clear to what extent integration of the senses during training is required for the observed effects. This study intended to elucidate the differential contributions of uni- and multisensory elements of music reading training in the resulting plasticity of abstract audiovisual incongruency identification. We used magnetoencephalography to measure the pre- and posttraining cortical responses of two randomly assigned groups of participants that followed either an audiovisual music reading training that required multisensory integration (AV-Int group) or a unisensory training that had separate auditory and visual elements (AV-Sep group). Results revealed a network of frontal generators for the abstract audiovisual incongruency response, confirming previous findings, and indicated the central role of anterior prefrontal cortex in this process. Differential neuroplastic effects of the two types of training in frontal and temporal regions point to the crucial role of multisensory integration occurring during training. Moreover, a comparison of the posttraining cortical responses of both groups to a group of musicians that were tested using the same paradigm revealed that long-term music training leads to significantly greater responses than the short-term training of the AV-Int group in anterior prefrontal regions as well as to significantly greater responses than both short-term training protocols in the left superior temporal gyrus (STG).

  15. Exploration of life experiences of positive growth in long-term childhood cancer survivors.

    2017-10-01

    The aim of this study was to explore experiences of positive growth in long-term childhood cancer survivors, from their perspective. Fifteen long-term survivors of childhood cancer provided descriptions of their experiences. Data were collected through face-to-face interviews and the analysis was based on Giorgi's phenomenological research method. The analysis of positive growth experienced by long-term childhood cancer survivors revealed three themes: self-directed life, normalcy in life, and inner maturity. Long-term survivors defined positive growth as a successful transition to a self-satisfactory life based on motivation acquired through their cancer experience and on subjective goal-setting, as well as becoming cancer-free and living a normal life within society. They seemed to have acquired optimistic, flexible, active attitudes toward life while demonstrating profound gratefulness and consideration of people around them, as well as prudent approaches to health. The findings of this study verified that long-term survivors of childhood cancer have grown positively due to their negative past experience. We expect these findings to contribute to the development of programs that promote positive growth in long-term childhood cancer survivors. Copyright © 2017 Elsevier Ltd. All rights reserved.

    This paper describes a research study conducted at Natura, a large Brazilian cosmetic company, in order to stimulate more systematic sustainable innovation practices by means of behavioural change.

    1996-12-31

    Since early 1980, Technip-Geoproduction (TPG), as designer or as installation contractor, has been using with success the float over system UNIDECK-TPG for the transportation and installation of integrated decks for offshore platforms. The concept offers the advantages of significant savings in transportation and installation cost by minimizing the installation time and offshore hook-up and eliminating the need for a heavy lift derrick barge. The paper describes the technology used for the installation, the required engineering studies, the consequences of using such a concept on platform design and the selection of an appropriate barge size to be used.

    Oligophagous herbivores must adjust their enzymatic machinery to the different host plant species they consume. If different hosts are used from one generation to the next, adaptation may be highly plastic, while if a single host is used over several generations, there may be a longer-term response due to natural selection. Using an experimental evolutionary approach, we investigated effects of long-term experience vs. short-term responses to different host plants in the oligophagous mustard leaf beetle Phaedon cochleariae. After 26 generations of continuous feeding on either Brassica rapa, Nasturtium officinale or Sinapis alba, freshly hatched larvae were kept on these plants or moved to one of the other host plants for ten days. Global transcriptional patterns as shown by microarrays revealed that between 1% and 16.1% of all 25,227 putative genes were differentially expressed in these treatments in comparison with the control line constantly feeding on B. rapa. A shift back from S. alba to B. rapa caused the largest changes in gene transcription and may thus represent the harshest conditions. Infection rates with a gregarine parasite were intermediate in all lines that were constantly kept on one host, but much lower or higher when short-term shifts to other host plants occurred. In conclusion, transcriptional plasticity in genes related to metabolism, digestion and general cellular processes plays a key role in long- and short-term responses of the beetle to changing host plant conditions, whereby the specific conditions also affect the interactions between the beetle host and its gregarine parasite. © 2017 John Wiley & Sons Ltd.

    The human brain is organized into large-scale functional networks that can flexibly reconfigure their connectivity patterns, supporting both rapid adaptive control and long-term learning processes. However, it has remained unclear how short-term network dynamics support the rapid transformation of instructions into fluent behaviour. Comparing fMRI data of a learning sample (N=70) with a control sample (N=67), we find that increasingly efficient task processing during short-term practice is associated with a reorganization of large-scale network interactions. Practice-related efficiency gains are facilitated by enhanced coupling between the cingulo-opercular network and the dorsal attention network. Simultaneously, short-term task automatization is accompanied by decreasing activation of the fronto-parietal network, indicating a release of high-level cognitive control, and a segregation of the default mode network from task-related networks. These findings suggest that short-term task automatization is enabled by the brain's ability to rapidly reconfigure its large-scale network organization involving complementary integration and segregation processes.

    Previous studies have suggested differential engagement of the bilateral fusiform gyrus in the processing of Chinese and English. The present study tested the possibility that long-term experience with Chinese language affects the fusiform laterality of English reading by comparing three samples: Chinese speakers, English speakers with Chinese experience, and English speakers without Chinese experience. We found that, when reading words in their respective native language, Chinese and English speakers without Chinese experience differed in functional laterality of the posterior fusiform region (right laterality for Chinese speakers, but left laterality for English speakers). More importantly, compared with English speakers without Chinese experience, English speakers with Chinese experience showed more recruitment of the right posterior fusiform cortex for English words and pseudowords, which is similar to how Chinese speakers processed Chinese. These results suggest that long-term experience with Chinese shapes the fusiform laterality of English reading and have important implications for our understanding of the cross-language influences in terms of neural organization and of the functions of different fusiform subregions in reading.

    A multi-model integration method is proposed to develop a multi-source and heterogeneous model for short-term solar flare prediction. Different prediction models are constructed on the basis of extracted predictors from a pool of observation databases. The outputs of the base models are normalized first because these established models extract predictors from many data resources using different prediction methods. Then weighted integration of the base models is used to develop a multi-model integrated model (MIM). The weight set that single models assign is optimized by a genetic algorithm. Seven base models and data from Solar and Heliospheric Observatory/Michelson Doppler Imager longitudinal magnetograms are used to construct the MIM, and then its performance is evaluated by cross validation. Experimental results showed that the MIM outperforms any individual model in nearly every data group, and the richer the diversity of the base models, the better the performance of the MIM. Thus, integrating more diversified models, such as an expert system, a statistical model and a physical model, will greatly improve the performance of the MIM.

    To describe and synthesize the extant research on women's experiences with preeclampsia into the postpartum period, when birth is necessary to save the mother's or infant's life. The PubMed, PsycINFO, CINAHL, and ISI Web of Science databases were searched for relevant articles published between 2004 and 2014. Although a comprehensive search was performed, only eight studies were found that answered the research question and were included in the review. Data were extracted and analyzed from each article that addressed women's experiences of pre-eclampsia: authors, year, country, study purpose, design, sample size, setting, main focus, data collection method, study findings, and limitations. The following themes emerged from the synthesis of how women experience severe preeclampsia: (a) From Feeling Fear and Closeness to Death to Feeling Hope, (b) Relationship With the Infant, (c) Separation From Loved Ones, and (d) Communication With Health Professionals. Fear and feeling close to death characterized the experience of childbirth for many of these women, and the premature birth was a shock for many. Having a newborn in the NICU was experienced as a transition from fear to hope as the newborn's life was sustained outside the womb. Separation of the mother from the newborn when one or both need special care remains a problem. Health care professionals must ensure that women in this situation receive the information and support they need and that the information is understood. This review revealed that more research is necessary regarding this specific mother-infant dyad and their families in the context of Western countries and developing countries.

    Living with a child with a long-term condition can result in challenges above usual parenting because of illness-specific demands. A critical evaluation of research exploring parents' experiences of living with a child with a long-term condition is timely because international health policy advocates that patients with long-term conditions become active collaborators in care decisions. A rapid structured review was undertaken (January 1999-December 2009) in accordance with the United Kingdom Centre for Reviews and Dissemination guidance. Three data bases (MEDLINE, CINAHL, PSYCINFO) were searched and also hand searching of the Journal of Advanced Nursing and Child: Care, Health and Development. Primary research studies written in English language describing parents' experiences of living with a child with a long-term condition were included. Thematic analysis underpinned data synthesis. Quality appraisal involved assessing each study against predetermined criteria. Thirty-four studies met the inclusion criteria. The impact of living with a child with a long-term condition related to dealing with immediate concerns following the child's diagnosis and responding to the challenges of integrating the child's needs into family life. Parents' perceived they are not always supported in their quest for information and forming effective relationships with health-care professionals can be stressful. Although having ultimate responsibility for their child's health can be overwhelming, parents developed considerable expertise in managing their child's condition. Parents' accounts suggest they not always supported in their role as manager for their child's long-term condition and their expertise, and contribution to care is not always valued. © 2013 John Wiley & Sons Ltd.

    In most developed countries, acute hospitals play a significant role in palliative care provision and are the setting in which most people die. They are often the setting where a life-limiting diagnosis is made and where patients present when symptoms develop or when they are not well managed. Understanding the experiences of hospital admissions for people with a life-limiting illness and their families is essential in understanding the role acute hospitals play in providing palliative care. The aim of this review is to synthesise current evidence regarding the experience of palliative care in an acute hospital setting from the perspectives of patient and family. An integrative review was completed using standard processes followed by a process of data extraction and synthesis. Using predefined search terms, literature was sourced from five electronic databases including MEDLINE (EBSCO), CINAHL, EMBASE, Cochrane and PsycINFO between January 1990 and November 2011. Reference lists from relevant articles were cross-checked and pertinent journals hand searched for articles. In total, 32 articles were included in the review. Five recurring themes were identified from the synthesised data: symptom control and burden, communication with health professionals, decision-making related to patient care and management, inadequate hospital environment and interpersonal relationships with health professionals. This review has identified that, largely as a result of study design, our knowledge of patient and family experiences of palliative care in an acute hospital remains limited to discrete aspects of care. Further research is required to explore the total patient and family experience taking into account all aspects of care including the potential benefits of hospital admissions in the last year of life.

    Bridges, James E.; Brown, Clifford A.; Bozak, Richard F.

    2014-01-01

    A wide-ranging series of tests have been completed that seek to map the effects of installation, including jet by jet interaction effects, on exhaust noise from various nozzles in forward flight. The primary data was far-field acoustic spectral directivity. The goals of the test series were (i) to generate enough data for empirical models of the different effects, and (ii) to provide data for advanced computational noise predictions methods applied to simplified yet realistic configurations. Data is presented that demonstrate several checks on data quality and that provide an overview of trends observed to date. Among the findings presented here: (i) Data was repeatable between jet rigs for single nozzles with and without surfaces to within +/- 0.5 dB. (ii) The presence of a second jet caused a strong reduction of the summed noise in the plane of the two plumes and an increase over the expected source doubling in most other azimuthal planes. (iii) The impact of the second jet was reduced when the jets were unheated. (iv) The impact of adding a second isolated rectangular jet was relatively independent of the nozzle aspect ratio up to aspect ratio 8:1. (v) Forward flight had similar impact on a high aspect ratio (8:1) jet as on an axisymmetric jet, except at the peak noise angle where the impact was less. (vi) The effect of adding a second round jet to a tightly integrated nozzle where the nozzle lip was less than a diameter from the surface was very dependent upon the length of the surface downstream of the nozzle. (vii) When the nozzles were rectangular and tightly integrated with the airframe surface the impact of a second jet was very dependent upon how close together the two jets were. This paper serves as an overview of the test; other papers presented in the same conference will give more detailed analysis of the results.

  10. Huilliche energy. Experiments in integration and ontological disagreements in a wind farm

    2017-12-01

    Full Text Available The island of Chiloé, in southern Chile, was the mise-en-scene of an unprecedented project: the development of a wind farm in which the Hulliche community, the ancestral people of the area, would own and run the operation. With the support of the Inter-American Development Bank, the aim of the project was the production of sustainable and renewable energies, but more importantly the integration of indigenous communities into the Chilean society via their participation in a high-value economic enterprise. Drawing on the idea of citizen participation as a form of experimentation, in this article we follow ethnographically the process of incubation, development and failure of this project. The case, we argue, allows a reflection about the risk of cultural aggression embedded in participatory experiments, but also about their capacities to crack open productive spaces for identity, political and ethical speculation. We coin the term “ontological disagreements” to indicate the ambivalences of participatory experiments and to debate about the future of indigenous engagement in energy projects.

    Full Text Available Background. In 2008, the English Department of Health appointed 16 'Integrated Care Pilots' which used a range of approaches to provide better integrated care. We report qualitative analyses from a three year multi-method evaluation to identify barriers and facilitators to successful integration of care. Theory and methods. Data were analysed from transcripts of 213 in-depth staff interviews, and from semi-structured questionnaires (the 'Living Document' completed by staff in pilot sites at six points over a two-year period. Emerging findings were therefore built from 'bottom up' and grounded in the data. However, we were then interested in how these findings compared and contrasted with more generic analyses. Therefore after our analyses were complete we then systematically compared and contrasted the findings with the analysis of barriers and facilitators to quality improvement identified in a systematic review by Kaplan et al (2010 and the analysis of more micro-level shapers of behaviour found in Normalisation Process Theory (May et al 2007. Neither of these approaches claims to be full blown theories but both claim to provide mid-range theoretical arguments which may be used to structure existing data and which can be undercut or reinforced by new data.Results and discussion. Many barriers and facilitators to integrating care are those of any large scale organisational change. These include issues relating to leadership, organisational culture, information technology, physician involvement, and availability of resources. However, activities which appear particularly important for delivering integrated care include personal relationships between leaders in different organisations, the scale of planned activities, governance and finance arrangements, support for staff in new roles, and organisational and staff stability.

    2011-07-01

    Full Text Available Our contemporary social and ecological problems, including climate change, peak oil and food security, necessitate solutions informed by multiple backgrounds that singular disciplines seem unable to provide, and possibly, are even incapable of providing. The increasing occurrence of multi-, inter- and transdisciplinary (MIT research projects speak to the recognition of that necessity. But as the literature and our own experiences bear out, just calling a project “beyond disciplinary” or integrated does not necessarily yield the intended outcomes or make progress toward alleviating the hurdles of bridging disciplines. Here we examine the distinctions between three categories (multidisciplinary, interdisciplinary and transdisciplinary of integrated research and offer reflections on how sustainability researchers can categorize their research to improve common understandings.

    2017-03-01

    determined that the key negative feature of Norwegian model of relations with the EU is «integration without representation», which means that Norway is not represented in the EU decision-making processes. But these processes actually determine the development of Norwegian legislation and policy. It has been grounded that in terms of international law and practice of international cooperation, the Norwegian model of relations with the EU is exceptional. Now the European Union does not see the perspective for Ukraine to get the EU membership. Consequently, it has been suggested that in such circumstances Norway experience can be very useful for Ukraine, particularly in the context of development of ever closer relations with the EU, and the integration of national economy into the EU internal market.

    2016-04-01

    Vagus nerve injury is a feared complication of antireflux surgery (ARS) that may negatively affect reflux control. The aim of the present prospective study was to evaluate short-term and long-term impact of vagus nerve injury, evaluated by pancreatic polypeptide response to insulin-induced hypoglycemia (PP-IH), on the outcome of ARS. In the period from 1990 until 2000, 125 patients with gastroesophageal reflux disease (GERD) underwent ARS at a single center. Before and 6 months after surgery, vagus nerve integrity testing (PP-IH), 24-h pH-monitoring, gastric emptying, and reflux-associated symptoms were evaluated. In 2014, 14-25 years after surgery, 110 patients were contacted again for evaluation of long-term symptomatic outcome using two validated questionnaires (Gastrointestinal Symptom Rating Scale (GSRS) and GERD-Health Related Quality of Life (HRQL)). Short-term follow-up: vagus nerve injury (PP peak ≤47 pmol/l) was observed in 23 patients (18%) 6 months after fundoplication. In both groups, a comparable decrease in reflux parameters and symptoms was observed at 6-month follow-up. Postoperative gastric emptying was significantly delayed in the vagus nerve injury group compared with the vagus nerve intact group. Long-term follow-up: patients with vagus nerve injury showed significantly less effective reflux control and a higher re-operation rate. Vagus nerve injury occurs in up to 20% of patients after ARS. Reflux control 6 months after surgery was not affected by vagus nerve injury. However, long-term follow-up showed a negative effect on reflux symptom control and re-operation rate in patients with vagus nerve injury.

This study assesses patient experience in the Integrated Care Pilot in North West London with the aim to help clinicians and policy makers understand patients’ acceptability of integrated care and design future initiatives.Methods: A survey was developed, validated and distributed to 2029 randomly selected practice patients identified as having a care plan.Results: A total of 405 questionnaires were included for analysis. Respondents identified a number of benefits associated with the pilot, including increased patient involvement in decision-making, improved patient-provider relationship, better organisation and access to care, and enhanced inter-professional communication. However, only 22.4% were aware of having a care plan, and of these only 37.9% had a copy of the care plan. Knowledge of care plans was significantly associated with a more positive experience.Conclusions: This study reinforces the view that integrated care can improve quality of care and patient experience. However, care planning was a complex and technically challenging process that occurred more slowly than planned with wide variation in quality and time of recruitment to the pilot, making it difficult to assess the sustainability of benefits.

This paper provides a highlight on theimplementation of integrated transport policy in the United Kingdom. Some key issues thatcan be learnt by the Indonesian government from their experience are discussed. This includesthe integration within and between all types of transport, integration with land use planning,integration with environment policy and integration with policies for education, health andwealth creations. In the implementation, the policy requires continuity and stability inorganization and politics, coordination in local transport plans, more devolution on powerand revenue funding from the government in addition to capital funding.Key words: traffic congestion, integrated transport policy

    CO2 leakage, either across the caprock or through faults, is a major concern for geologic carbon storage. To assess the caprock sealing capacity and the strength of faults, we investigate clay-rich geomaterials in the laboratory. We focus on the thermo-hydro-mechanical coupled processes that shale may undergo during CO2 storage. Specimens of Opalinus clay - a Swiss shale - are brought to the conditions of suitable storage formations (1 km depth) and are fully saturated with in-situ brine. Poro-thermo-mechanical parameters are measured in drained, undrained, and unjacketed compression experiments. We use the measured parameters at the laboratory as input data to a numerical model that simulates CO2 injection in a deep saline aquifer bounded by a low-permeable fault. We find that the caprock sealing capacity is maintained and that even the fault may undergo a series of microseismic events, leakage is unlikely to occur through the ductile clay-rich fault.

    We report on a cost-effective easy-access software developed for the functional integration of the clinical records and history of oncologic patients with the management of the Day Hospital of the Radiotherapy Department of the University Hospital A. Gemelli, in Rome. The software was designed to archive the clinical records and history of oncologic patients and the relative chemotherapy, to manage the examination scheduling, to draw up nursing files with the planned therapy and to make statistical analyses of the department activity. Five forms are available: the patient form, recording patient data; the admission form, recording the type of therapy (e.g., chemotherapy, tests, medical examinations, etc.), the relative cost and chemotherapy protocol, detailing for instance the type of drug; the nursing file, detailing chemotherapy schedule and the dilution of each drug; the menu, to select and retrieve any record. The minimum configuration requires a 386 Intel CPU, 4 Mb RAM and 4 Mb free on the hard disk. The software is the File Maker Pro 2.1 for Windows which can interact with Apple Macintosh computers. Since October, 1995, we have saved the clinical records of 272 oncologic outpatients (2415 entries in all), with a mean of 201/month. This computer system permitted us to save and retrieve data for both clinical and didactic purposes and to plan our activity. One year after it was implemented and used in clinical practice, the system is a cost-effective and user-friendly tool for the management of the Radiochemotherapy Day Hospital of our Radiotherapy Department.

    The aim of this integrative review was to describe the organisational, unregulated nurse, and resident outcomes associated with effective supervisory performance of regulated nurses (registered nurses or registered practical nurses) in long-term care homes. While there are data on the influence of regulated nurse staffing levels on resident outcomes, the influence of effective supervisory performance of regulated nurses on resident and organisational outcomes, nursing assistant outcomes have yet to be comprehensively explored. A search of six databases was made for articles dating from 2000 to 2015. Twenty-four articles were selected and an integrative review was performed. Effective nurse supervision had statistically significant positive associations (P nurse and resident outcomes: nurse assistant job satisfaction, turnover/intention to leave, effectiveness, decision making, job stress and consumer satisfaction. Qualitative analyses corroborate these findings. There appear to be some associations between effective supervisory performance of regulated nurses with positive organisational, unregulated nursing and resident outcomes. Nursing managers and leaders in long-term care may promote improvements in effective nurse supervision performance as a way of reducing turnover and improving resident outcomes. © 2016 John Wiley & Sons Ltd.

    Full Text Available Long term video game players (VGPs have been reported to exhibit superior visual and motor skills compared with non-video-game controls (NVGCs. However, the neural basis underlying the enhanced behavioral performance remains largely unknown. To clarify this issue, the present study compared the whiter matter integrity within the corticospinal tracts (CST, the superior longitudinal fasciculus (SLF, the inferior longitudinal fasciculus (ILF, and the inferior fronto-occipital fasciculus (IFOF between the VGPs and the NVGCs using diffusion tensor imaging (DTI. Compared with the NVGCs, voxel-wise comparisons revealed significantly higher fractional anisotropy (FA value in some regions within the left CST, left SLF, bilateral ILF and IFOF in VGPs. Furthermore, higher FA value at the cerebral peduncle level of the left CST predicted faster response in visual attention task. These results suggested that the higher WM integrity in the motor and higher-tier visual pathways is associated with long-term video-game playing, which may contribute to the understanding of the neuromechanism of the effect of video game play on the motor and visual process performance.

    2016-10-01

    Full Text Available The APEC Climate Center (APCC produces climate prediction information utilizing a multi-climate model ensemble (MME technique. In this study, four different downscaling methods, in accordance with the degree of utilizing the seasonal climate prediction information, were developed in order to improve predictability and to refine the spatial scale. These methods include: (1 the Simple Bias Correction (SBC method, which directly uses APCC's dynamic prediction data with a 3 to 6 month lead time; (2 the Moving Window Regression (MWR method, which indirectly utilizes dynamic prediction data; (3 the Climate Index Regression (CIR method, which predominantly uses observation-based climate indices; and (4 the Integrated Time Regression (ITR method, which uses predictors selected from both CIR and MWR. Then, a sampling-based temporal downscaling was conducted using the Mahalanobis distance method in order to create daily weather inputs to the Soil and Water Assessment Tool (SWAT model. Long-term predictability of water quality within the Wecheon watershed of the Nakdong River Basin was evaluated. According to the Korean Ministry of Environment's Provisions of Water Quality Prediction and Response Measures, modeling-based predictability was evaluated by using 3-month lead prediction data issued in February, May, August, and November as model input of SWAT. Finally, an integrated approach, which takes into account various climate information and downscaling methods for water quality prediction, was presented. This integrated approach can be used to prevent potential problems caused by extreme climate in advance.

    To identify in the literature how the experiences of women age 35 or above are described in terms of pregnancy. Integrative review based on MEDLINE/PubMed, CINAHL, LILACS, and SciELO databases, with no time period constraint. Eighteen studies that dealt with the experiences of pregnant women at an advanced maternal age were selected and analyzed. The studies evidenced four theme categories: the search for information, which pointed to a deficit of information supplied by health care professionals; perceiving the risks, which pointed to women's concerns about their own health and their children's; the ideal moment for motherhood, with different reasons for postponing it; and adjusting to a new routine, showing a concern regarding changes in daily life. From the results, it was possible to understand that other factors, in addition to those that include risks, are present in the experiences of older pregnant women and point to a need to involve such aspects in nursing care to create comprehensive strategies that are aligned with these women's needs.

  14. Geological Disposal of Radioactive Waste: A Long-Term Socio-Technical Experiment.

    Schröder, Jantine

    2016-06-01

    In this article we investigate whether long-term radioactive waste management by means of geological disposal can be understood as a social experiment. Geological disposal is a rather particular technology in the way it deals with the analytical and ethical complexities implied by the idea of technological innovation as social experimentation, because it is presented as a technology that ultimately functions without human involvement. We argue that, even when the long term function of the 'social' is foreseen to be restricted to safeguarding the functioning of the 'technical', geological disposal is still a social experiment. In order to better understand this argument and explore how it could be addressed, we elaborate the idea of social experimentation with the notion of co-production and the analytical tools of delegation, prescription and network as developed by actor-network theory. In doing so we emphasize that geological disposal inherently involves relations between surface and subsurface, between humans and nonhumans, between the social, material and natural realm, and that these relations require recognition and further elaboration. In other words, we argue that geological disposal concurrently is a social and a technical experiment, or better, a long-term socio-technical experiment. We end with proposing the idea of 'actor-networking' as a sensitizing concept for future research into what geological disposal as a socio-technical experiment could look like.

    Most reports of scientific misconduct have been focused on principal investigators and other scientists (e.g., biostatisticians) involved in the research enterprise. However, by virtue of their position, research coordinators are often closest to the research field where much of misconduct occurs. The purpose of this study was to describe research coordinators' experiences with scientific misconduct in their clinical environment. The descriptive design was embedded in a larger cross-sectional national survey. A total of 266 respondents, predominately registered nurses, who answered "yes" to having firsthand knowledge of scientific misconduct in the past year, provided open-ended question responses. Content analysis was conducted by the research team, ensuring agreement of core categories and subcategories of misconduct. Research coordinators most commonly learned about misconduct via firsthand witness of the event, with the principal investigator being the person most commonly identified as the responsible party. Five major categories of misconduct were identified: protocol violations, consent violations, fabrication, falsification, and financial conflict of interest. In 70% of cases, the misconduct was reported. In most instances where misconduct was reported, some action was taken. However, in approximately 14% of cases, no action or investigation ensued; in 6.5% of cases, the coordinator was fired or he or she resigned. This study demonstrates the need to expand definitions of scientific misconduct beyond fabrication, falsification, and plagiarism to include other practices. The importance of the ethical climate in the institution in ensuring a safe environment to report and an environment where evidence is reviewed cannot be overlooked.

  16. Registered Nurses' work experiences: personal accounts integrated with professional identity.

    2004-05-01

    The work context is important for the development of Registered Nurses' skills and identity as professionals, but the work context and organization can also hinder their professional development. This paper reports a study whose purpose was to understand the meaning of Registered Nurses' narratives of their work experience 5 years after graduation. Data were collected in 2001 from interviews with 16 Registered Nurses 5 years after graduation and analysed using a phenomenological hermeneutic method, influenced by the philosophy of Paul Ricoeur. Analyses of the narratives resulted in three themes: 'The meaning of caring and protection of patients', 'The meaning of work organization in nurses' work' and 'The implied meaning of using one's individual attributes in one's professional role'. Since the number of nurses participating in the study is small, it is important to re-contextualize the results when transferring them to other contexts. There is a complex interrelationship between the health care organization, individual attributes of nurses (including self-esteem) and patient care. Provision of adequate resources and support for nurses' professional and personal development is needed to ensure high quality patient care, and these are political issues.

    The nature of near-death-experiences (NDEs) is largely unknown but recent evidence suggests the intriguing possibility that NDEs may refer to actually "perceived," and stored, experiences (although not necessarily in relation to the external physical world). We adopted an integrated approach involving a hypnosis-based clinical protocol to improve recall and decrease memory inaccuracy together with electroencephalography (EEG) recording in order to investigate the characteristics of NDE memories and their neural markers compared to memories of both real and imagined events. We included 10 participants with NDEs, defined by the Greyson NDE scale, and 10 control subjects without NDE. Memories were assessed using the Memory Characteristics Questionnaire. Our hypnosis-based protocol increased the amount of details in the recall of all kind of memories considered (NDE, real, and imagined events). Findings showed that NDE memories were similar to real memories in terms of detail richness, self-referential, and emotional information. Moreover, NDE memories were significantly different from memories of imagined events. The pattern of EEG results indicated that real memory recall was positively associated with two memory-related frequency bands, i.e., high alpha and gamma. NDE memories were linked with theta band, a well-known marker of episodic memory. The recall of NDE memories was also related to delta band, which indexes processes such as the recollection of the past, as well as trance states, hallucinations, and other related portals to transpersonal experience. It is notable that the EEG pattern of correlations for NDE memory recall differed from the pattern for memories of imagined events. In conclusion, our findings suggest that, at a phenomenological level, NDE memories cannot be considered equivalent to imagined memories, and at a neural level, NDE memories are stored as episodic memories of events experienced in a peculiar state of consciousness.

    Neural network models describe semantic priming effects by way of mechanisms of activation of neurons coding for words that rely strongly on synaptic efficacies between pairs of neurons. Biologically inspired Hebbian learning defines efficacy values as a function of the activity of pre- and post-synaptic neurons only. It generates only pair associations between words in the semantic network. However, the statistical analysis of large text databases points to the frequent occurrence not only of pairs of words (e.g., "the way") but also of patterns of more than two words (e.g., "by the way"). The learning of these frequent patterns of words is not reducible to associations between pairs of words but must take into account the higher level of coding of three-word patterns. The processing and learning of pattern of words challenges classical Hebbian learning algorithms used in biologically inspired models of priming. The aim of the present study was to test the effects of patterns on the semantic processing of words and to investigate how an inter-synaptic learning algorithm succeeds at reproducing the experimental data. The experiment manipulates the frequency of occurrence of patterns of three words in a multiple-paradigm protocol. Results show for the first time that target words benefit more priming when embedded in a pattern with the two primes than when only associated with each prime in pairs. A biologically inspired inter-synaptic learning algorithm is tested that potentiates synapses as a function of the activation of more than two pre- and post-synaptic neurons. Simulations show that the network can learn patterns of three words to reproduce the experimental results.

    Full Text Available The article presents the results of a calculation-to-experiment (C/E discrepancy analysis for a new evaluation of differential (measuring neutron transmission and integral experiments from the International Handbook of Evaluated Criticality Benchmark Safety Experiments. The experiments were carried out to examine the properties of fuel and structural materials. Based on these experiments, proposals were made for silicon-28 and uranium-235 resonance parameters corrections. This series of studies is considered as a sample joint analysis framework for differential and integral experiments required to correct nuclear data files of the ROSFOND evaluated neutron data library. The authors investigate the possible sources of the C/E discrepancies in their relation to uncertainties in the neutron cross-section resonance structure as well as resonance effects influencing the measured characteristics.

  5. Soil Organic Matter Dynamics in the Rothamsted Long-term Experiments

    MacDonald, A.; Poulton, P.

    2009-04-01

    Soil science research at Rothamsted dates from 1843 when John Bennet Lawes and Joseph Henry Gilbert started the first of a series of what became long-term field experiments. The main object of these experiments was to examine the effect of inorganic and organic fertilisers and manures on crop yield and soil fertility. These "Classical Field Experiments" included studies on winter wheat (Broadbalk 1843), spring barley (Hoos Barley 1852) and permanent grassland (Park Grass 1856). Additional experiments were established in the 20th century to examine the value of ley-arable cropping, including the Highfield and Fosters Ley-arable experiments (1948) and the Woburn Ley-arable experiment (1938). More recently, the effects of incorporating organic manures and cereal straw have been examined. Early results quickly showed the benefits of inorganic N and P fertilisers on crop production, but the effects of contrasting land uses and management practices on soil properties emerged more slowly. Measurements of soil organic carbon (C) and nitrogen (N) in soils taken at intervals from the long-term experiments indicate that the rate of soil organic matter (SOM) accumulation is controlled largely by the balance between the rate of organic matter inputs and its oxidation rate, and that these are strongly influenced by land use and management, soil texture (especially clay content) and climate. A recent examination of soil organic C data from two long-term grassland experiments in the UK (including Park Grass) indicates that any changes observed in soil organic C under long-term grasslands over the past 40 years are more likely to be due to changes in land use and management rather than climate change. Data from the Rothamsted Long-term experiments have been used to develop and test biogeochemical models of C and N dynamics. In particular, the Roth-C model has successfully simulated soil C dynamics in the long-term experiments at Rothamsted and elsewhere. This model uses several

    The Hartree and Exchange terms can become a computational intensive task in DFT and TDDFT calculations of large structures. Existing methods use either iterative solvers such as conjugate gradient or multi-grid methods or use FFT for the calculation of those terms via the solution of the Poisson equation. With iterative solvers, the problem of setting the boundary conditions is often time consuming by itself as approximations such as the multipole expansion might not converge easily for structures with high aspect ratio. With FFT one needs to use a larger box for the calculation of finite systems. We present an alternative integral method to calculate the Hartree and Exchange terms in DFT and TDDFT. We first describe the algorithm and show that it has O(N) scaling for elongated structures. We then show some examples of long 1D chains ground state and time dependent calculations that use this algorithm. Finally we discuss some possible applications for more advanced functionals that include the Fock exchange or screened exchange.

    Many prostate cancer survivors have lasting symptoms and disease-related concerns for which they seek information. To understand survivors' information-seeking experiences, we examined the topics of their information searches, their overall perceptions of the search, and perceptions of their health information seeking self-efficacy (i.e., confidence in their ability to obtain information). We hypothesized that negative search experiences and lower health information seeking self-efficacy would be associated with certain survivor characteristics such as non-white race, low income, and less education. This was a retrospective study using data from the Michigan Prostate Cancer Survivor Study (state-based survey of long-term prostate cancer survivor outcomes, N = 2499, response rate = 38 %). Participants recalled their last search for information and reported the topics and overall experience. We conducted multivariable regression to examine the association between survivor characteristics and the information-seeking experience. Nearly a third (31.7 %) of prostate cancer survivors (median age of 76 years and 9 years since diagnosis) reported having negative information-seeking experiences when looking for information. However, only 13.4 % reported having low health information-seeking self-efficacy. Lower income and less education were both significantly associated with negative information-seeking experiences. Our findings suggest that many long-term prostate cancer survivors have negative experiences when searching for information, and lower income and less education were survivor factors related to negative information-seeking experiences. We advocate for ongoing, information needs assessment at the point-of-care as the survivorship experience progresses to assess and potentially improve survivors' quality of life.

    Full Text Available OBJECTIVE: to test the clinical utility of an early amplitude-integrated electroencephalography (aEEG to predict short-term neurological outcome in term newborns at risk of neurology injury. METHODS: this was a prospective, descriptive study. The inclusion criteria were neonatal encephalopathy, neurologic disturbances, and severe respiratory distress syndrome. Sensitivity, specificity, positive and negative predictive values, and likelihood ratio (LR were calculated. Clinical and demographic data were analyzed. Neurological outcome was defined as the sum of clinical, electroimaging, and neuroimaging findings. RESULTS: ten of the 21 monitored infants (48% presented altered short-term neurologic outcome. The aEEG had 90% sensitivity, 82% specificity, 82% positive predictive value, and 90% negative predictive value. The positive LR was 4.95, and the negative LR was 0.12. In three of 12 (25% encephalopathic infants, the aEEG allowed for a better definition of the severity of their condition. Seizures were detected in eight infants (38%, all subclinical at baseline, and none had a normal aEEG background pattern. The status of three infants (43% evolved and required two or more drugs for treatment. CONCLUSIONS: in infants with encephalopathy or other severe illness, aEEG disturbances occur frequently. aEEG provided a better classification of the severity of encephalopathy, detected early subclinical seizures, and allowed for monitoring of the response to treatment. aEEG was a useful tool at the neonatal intensive care unit for predicting poor short-term neurological outcomes for all sick newborn.

    Full Text Available In urban flood modeling, so-called porosity shallow water equations (PSWEs, which conceptually account for unresolved structures, e.g., buildings, are a promising approach to addressing high CPU times associated with state-of-the-art explicit numerical methods. The PSWE can be formulated with a single porosity term, referred to as the single porosity shallow water model (SP model, which accounts for both the reduced storage in the cell and the reduced conveyance, or with two porosity terms: one accounting for the reduced storage in the cell and another accounting for the reduced conveyance. The latter form is referred to as an integral or anisotropic porosity shallow water model (AP model. The aim of this study was to analyze the differences in wave propagation speeds of the SP model and the AP model and the implications of numerical model results. First, augmented Roe-type solutions were used to assess the influence of the source terms appearing in both models. It is shown that different source terms have different influences on the stability of the models. Second, four computational test cases were presented and the numerical models were compared. It is observed in the eigenvalue-based analysis as well as in the computational test cases that the models converge if the conveyance porosity in the AP model is close to the storage porosity. If the porosity values differ significantly, the AP model yields different wave propagation speeds and numerical fluxes from those of the BP model. In this study, the ratio between the conveyance and storage porosities was determined to be the most significant parameter.

    Bio-ontologies provide terminologies for the scientific community to describe biomedical entities in a standardized manner. There are multiple initiatives that are developing biomedical terminologies for the purpose of providing better annotation, data integration and mining capabilities. Terminology resources devised for multiple purposes inherently diverge in content and structure. A major issue of biomedical data integration is the development of overlapping terms, ambiguous classifications and inconsistencies represented across databases and publications. The disease ontology (DO) was developed over the past decade to address data integration, standardization and annotation issues for human disease data. We have established a DO cancer project to be a focused view of cancer terms within the DO. The DO cancer project mapped 386 cancer terms from the Catalogue of Somatic Mutations in Cancer (COSMIC), The Cancer Genome Atlas (TCGA), International Cancer Genome Consortium, Therapeutically Applicable Research to Generate Effective Treatments, Integrative Oncogenomics and the Early Detection Research Network into a cohesive set of 187 DO terms represented by 63 top-level DO cancer terms. For example, the COSMIC term 'kidney, NS, carcinoma, clear_cell_renal_cell_carcinoma' and TCGA term 'Kidney renal clear cell carcinoma' were both grouped to the term 'Disease Ontology Identification (DOID):4467 / renal clear cell carcinoma' which was mapped to the TopNodes_DOcancerslim term 'DOID:263 / kidney cancer'. Mapping of diverse cancer terms to DO and the use of top level terms (DO slims) will enable pan-cancer analysis across datasets generated from any of the cancer term sources where pan-cancer means including or relating to all or multiple types of cancer. The terms can be browsed from the DO web site (http://www.disease-ontology.org) and downloaded from the DO's Apache Subversion or GitHub repositories.

    Full Text Available The purpose of this paper is to study the Canadian experience of new approaches development for integration of gender-based analysis into the government activities on the federal, provincial and municipal levels. Gender-based analysis is one of the main tools of gender mainstreaming in Canada. The paper analyzes new approaches and definitions of the term «gender-based analysis», which became the result of conceptual shifts in the understanding of the nature of gender-based analysis by several jurisdictions in Canada. It is considered a variety of practical tools – checklists, gender lenses, questions, graphs and specific cases – which are geared specifically toward a specific technical specialization of government agencies in Canada. It is noted that these tools are offered within the methods developed to link gender-based analysis to the functions of government performance. The conclusion is that Canada is a world leader not only in the use of gender-based analysis in the process of public policymaking, but further improvement of the practical tools, and expanding its scope.

    Full Text Available California's Mediterranean agro-ecosystems are a major source of U.S. fruits and vegetables, and vulnerable to future extremes of precipitation and temperature brought on by climate change, including increased drought and flooding, and more intense and longer heat waves. To develop resilience to these threats, strategies are necessary for climate-smart management of soil and water. Long-term, large-scale, replicated ecological experiments provide unique testbeds for studying such questions. At the UC Davis Russell Ranch Sustainable Agriculture Facility (RRSAF, the 100-year Century Experiment, initiated in 1992, is investigating the effects of multiple farming practices in a farm-scale replicated study of 10 row crop cropping systems. It includes different fertility management systems: organic, conventional and hybrid (conventional plus winter cover crop systems; different crops: wheat, tomatoes, corn, alfalfa, cover crops and grasslands; and different irrigation systems: rainfed, flood irrigated and drip irrigated. We briefly describe and report on a selection of long-term experiments conducted at RRSAF investigating soil management and irrigation practices, which are an important focus for developing climate-smart strategies in Mediterranean systems. For example, long-term monitoring of soil carbon content revealed that most crop systems have experienced a small increase in soil carbon since 1993, and increases in organically managed plots were substantially higher. As RRSAF continues to build upon this rich dataset from one of a very few long-term row crop experiments in Mediterranean ecosystems, it provides a testbed for identifying climate-smart solutions for these agronomically important ecosystems.

    Full Text Available The objective of the study was to compare the impact of three systems of multiannual fertilization applied in two long-term field experiments on the content of phenolic compounds in the soil. In the study, both natural (manure, slurry and mineral (NPK fertilizers were used, along with combined, organic-and-mineral fertilization. Experiment I was established in 1972 on grey brown podzolic soil; experiment II, in 1973 on brown soil. In both experiments crops were cultivated in a 7-year rotation, with a 75% share of cereals. The experimental samples were taken from the top layer of soil after 36 (experiment I and 35 (experiment II years following the establishment of the experiments. It was demonstrated that the presence of phenolic compounds in the soils was significantly dependent on the contents of organic C and total N, type of soil and the type and dose of used fertilizers. In grey brown podzolic soil, the content of total phenolic compounds was at a lower level than the content found in brown soil. Multiannual fertilization contributed to an increase in the content of total phenolic compounds in relation to the values obtained in control objects, which was particularly reflected in the soil originating from objects fertilized with slurry applied at a dose being equivalent to manure in terms of the amount of introduced organic carbon. The percentage of water-soluble phenols in the total content of these compounds in grey brown podzolic soil was at the level of 18.4%, while in brown soil it amounted to 29.1%.

    An integrated forward osmosis (FO) and membrane distillation (MD) system has great potential for sustainable wastewater reuse. However, the fouling and long-term durability of the system remains largely unknown. This study investigates the fouling behaviour and efficiency of cleaning procedures of FO and MD membranes used for treating domestic wastewater. Results showed that a significant decline in flux of both FO and MD membranes were observed during treatment of wastewater with organic foulants. However, shear force generated by the increased cross-flow physically removed the loosely attached foulants from the FO membrane surface and resulted in 86-88% recovery of flux by cleaning with tap water. For the MD membrane, almost no flux recovery was achieved due to adsorption of organic foulants on the hydrophobic membrane surface, thus indicating significant irreversible fouling/wetting, which may not be effectively cleaned even with chemical reagents. Long-term (10 d) tests showed consistent performance of the FO membrane by rejecting the contaminants. However, organic foulants reduced the hydrophobicity of the MD membrane, caused wetting problems and allowed contaminants to pass through. The results demonstrate that combination of the FO and MD processes can effectively reduce irreversible membrane fouling and solve the wetting problem of the MD membrane.

    Since the failure of Nirex application to build a Rock Characterisation Facility near Sellafield in 1997, Nirex has been applying lessons learnt from that failure. Some of the issues involved are generic and relate to the process by which legitimate authority can be gained for government policy development, the structure of the nuclear industry and the behaviour of institutions. Transparency must be central to the culture of organisations attempting to win public acceptance. In the UK, the Department for Environment, Food and Rural Affairs (DEFRA) have started a consultation process - stage one completed in March 2002 - to consult about the safe management of radioactive waste. Nirex has modified its approach to long-term waste management, using a concept of phased (stepwise and reversible) geological disposal. Nirex also provides waste producers with advice on, and endorsement of, the packaging and transport of wastes. Through these examples, this paper will demonstrate how Nirex is providing an integrated approach to the long-term management of radioactive wastes in the UK. (orig.)

    The LTDE-SD experiment, (Long Term Sorption Diffusion Experiment) aimed at increasing the scientific knowledge of sorption and diffusion under in situ conditions and to provide data for performance and safety assessment calculations. Performance and results of the in situ experiment phase are presented in the report. In total, 21 radionuclide trace elements and one stable trace element were injected, circulated and sampled for approx6.5 months in a closed borehole section. The trace elements represented non-sorbing tracers and sorbing tracers for which the sorption was dominated by a cation exchange mechanism, a surface complexation mechanism, or dependent on an electrochemical reduction in order to reach the tetravalent state (oxidation state IV) considered very strongly sorbing. The borehole section in contact with the tracer labelled groundwater consisted in part of a natural fracture surface and a borehole section in the unaltered matrix rock, devoid of natural fractures. Water samples were regularly extracted and analysed for trace element concentration and a few ion exchange speciation and filtered samplings were also conducted. Independent colloid filtering and chemical speciation calculations were performed in support the evaluation. Sorption was demonstrated for a series of elements present in the experiment. The amounts lost of the different respective tracers from the aqueous phase follow very well the general understanding of the relative sorption strength of the tracers, as inferred from e.g. batch sorption experiments and dynamic in situ tracer experiments. The chemical speciation calculations of the different tracers were in line with the results of the ion exchange speciation performed during the experiment. With the exception of UO{sub 2} 2+ carbonate complexes formed, no strong indications were obtained that aqueous complexation prevents adsorption under the chemical conditions of the experiment. The 20 nm filtered sampling indicated that

    There is evidence to suggest that the long-term doctor-patient relationship is crucial in the management of chronic illness such as chronic kidney disease. While previous research has focused on patient views of the doctor-patient relationship, research exploring the doctor's experiences of this unique dynamic is lacking, leading to a gap in our understanding. Therefore, an enhanced appreciation of the experience of the doctor is important and could have potential implications for medical training and service organisation. In this paper, we report the first known study exploring the experience of consultant nephrologists in the long-term doctor-patient relationship. Seven male consultant nephrologists (mean age of 48 years) took part in semi-structured interviews, and data were analysed using interpretative phenomenological analysis (IPA). Three main themes were identified from the analysis: 'Defining my professional identity', 'Relating to the patient' and 'Coping with the job'. Participants had difficulty in defining their role as doctors, discussing themselves as being more than a doctor and comparing themselves with other medical specialties to help them define their identity. Although participants enjoyed forming long-term relationships with patients and the closeness this involved, they discussed the acute scenarios of saving lives as the most rewarding aspect of their job and used coping mechanisms that enabled them to remain detached in the relationship. © 2014 European Dialysis and Transplant Nurses Association/European Renal Care Association.

    Full Text Available Craniopharyngioma are rare histologically benign brain tumors that develop in the pituitary- hypothalamic area. They may invade nearby anatomical structures causing significant rates of neurological, neurocognitive and endocrinological complications including remarkable hypothalamic damage. Information regarding long term implications of the tumors and treatment in the pediatric population is accumulating, and treatment goals appear to be changing accordingly. In this review we aim to present data regarding long term complications of craniopharyngioma in children and adolescents and our experience from a large tertiary center. Hypothalamic dysfunction was noted to be the most significant complication, adversely affecting quality of life in survivors. Obesity, fatigue and sleep disorders are the most notable manifestations of this dysfunction, and treatment is extremely difficult. Changes in management in recent years show a potential for improved long term outcomes; we found a trend towards less aggressive surgical management and increasing use of adjuvant treatment, accompanied by a decrease in complication rates.

    Integrated care is the combination of different healthcare services with the goal to provide comprehensive, seamless, effective and efficient patient care. Assessing the experiences of healthcare professionals (HCPs) is an important aspect when evaluating integrated care strategies. The aim of this rapid review was to investigate if quantitative surveys used to assess HCPs' experiences with integrated care capture all the aspects highlighted as being important in qualitative research, with a view to informing future survey development. The review considered all types of health professionals in primary care, and hospital and specialist services, with a specific focus on the provision of integrated care aimed at improving the patient journey. PubMed, CINAHL and grey literature sources were searched for relevant surveys/program evaluations and qualitative research studies. Full text articles deemed to be of relevance to the review were appraised for methodological quality using abridged critical appraisal instruments from the Joanna Briggs Institute. Data were extracted from included studies using standardized data extraction templates. Findings from included studies were grouped into domains based on similarity of meaning. Similarities and differences in the domains covered in quantitative surveys and those identified as being important in qualitative research were explored. A total of 37 studies (19 quantitative surveys, 14 qualitative studies and four mixed-method studies) were included in the review. A range of healthcare professions participated in the included studies, the majority being primary care providers. Common domains identified from quantitative surveys and qualitative studies included Communication, Agreement on Clear Roles and Responsibilities, Facilities, Information Systems, and Coordination of Care and Access. Qualitative research highlighted domains identified by HCPs as being relevant to their experiences with integrated care that have not

    Shale-gas development in Pennsylvania since 2003 has resulted in about 19 documented cases of methane migration from the deep subsurface (7,0000) to drinking water aquifers, soils, domestic water wells, and buildings, including one explosion. In all documented cases, the methane leakage was due to inadequate wellbore integrity, possibly aggravated by hydrofracking. The leakage of methane is instructive on the potential for CO{sub 2} leakage from sequestration operations. Although there are important differences between the two systems, both involve migrating, buoyant gas with wells being a primary leakage pathway. The shale-gas experience demonstrates that gas migration from faulty wells can be rapid and can have significant impacts on water quality and human health and safety. Approximately 1.4% of the 2,200 wells drilled into Pennsylvania's Marcellus Formation for shale gas have been implicated in methane leakage. These have resulted in damage to over 30 domestic water supplies and have required significant remediation via well repair and homeowner compensation. The majority of the wellbore integrity problems are a result of over-pressurization of the wells, meaning that high-pressure gas has migrated into an improperly protected wellbore annulus. The pressurized gas leaks from the wellbore into the shallow subsurface, contaminating drinking water or entering structures. The effects are localized to a few thousands of feet to perhaps two-three miles. The degree of mixing between the drinking water and methane is sufficient that significant chemical impacts are created in terms of elevated Fe and Mn and the formation of black precipitates (metal sulfides) as well as effervescing in tap water. Thus it appears likely that leaking CO{sub 2} could also result in deteriorated water quality by a similar mixing process. The problems in Pennsylvania highlight the critical importance of obtaining background data on water quality as well as on problems associated with

    Surgical interventions have proven to be more effective than other measures in the treatment of morbid obesity. The short-term outcomes of the various surgical interventions have been well documented in the literature, with fewer reports on long-term outcomes. The reported long-term outcome of the vertical-banded gastroplasty (VBG) is conflicting. The aim of the present study was to evaluate our long-term experience with VBG. A retrospective review of a prospectively maintained database was conducted. Records of patients who underwent VBG five or more years ago were retrieved. An analysis of the long-term weight changes and reported complications was conducted. The study included 150 patients: 43 males (29%) and 107 females (71%). Their mean age was 30 years old (12-53), and the mean body mass index (BMI) was 47 ± 8.4 kg/m2. Patients were followed up for an average of 8 years (5-11). More than 60 % of patients had good long-term weight loss (EWL > 50%). A significant negative correlation was found between the excess weight loss percent (EWL%) and the pre-operative BMI (p gastric bypass (3.3%), while two patients (1.3%) had reversal of the procedure. Late complications included mesh erosion in three cases, staple line dehiscence in two patients, and stomal stenosis in six patients. VBG could be a long-term effective intervention for the treatment of morbid obesity. Good selection is the cornerstone for long-term success. Late complication rate is acceptable after VBG. VBG is a specifically useful tool under stringent financial circumstances.

    Full Text Available This paper attempts to look at the connection between political and economic integration in the cross-Strait relations, while also referring in many cases to the European experience and theories of the European integration. One of the main conclusions of the paper is that economic globalisation does not lead to political integration of the two polities. Modern theories of labour division and their conclusions on the distribution of economic gains underline that a peaceful free trade environment without major political conflicts endorses the formation of smaller political entities and this environment basically contributes to healthy competition among these countries and to diversity of political and economic regimes.

    It is predicted that quantum computers will dramatically outperform their conventional counterparts. However, large-scale universal quantum computers are yet to be built. Boson sampling is a rudimentary quantum algorithm tailored to the platform of linear optics, which has sparked interest as a rapid way to demonstrate such quantum supremacy. Photon statistics are governed by intractable matrix functions, which suggests that sampling from the distribution obtained by injecting photons into a linear optical network could be solved more quickly by a photonic experiment than by a classical computer. The apparently low resource requirements for large boson sampling experiments have raised expectations of a near-term demonstration of quantum supremacy by boson sampling. Here we present classical boson sampling algorithms and theoretical analyses of prospects for scaling boson sampling experiments, showing that near-term quantum supremacy via boson sampling is unlikely. Our classical algorithm, based on Metropolised independence sampling, allowed the boson sampling problem to be solved for 30 photons with standard computing hardware. Compared to current experiments, a demonstration of quantum supremacy over a successful implementation of these classical methods on a supercomputer would require the number of photons and experimental components to increase by orders of magnitude, while tackling exponentially scaling photon loss.

    Full Text Available Aims: This study aimed to establish and compare the effects of brief sensory deprivation on individuals differing in trait hallucination proneness. Method: 18 participants selected for high hallucination-proneness were compared against 18 participants rating low on this trait. The presence of psychotic-like experiences, and participants’ cognitive appraisals of these, was evaluated in three different settings: at baseline, in a ‘secluded office’ environment, and in light-and-sound sensory deprivation.Results: Psychotic-like experiences were experienced significantly more often in sensory deprivation for both groups. In particular both experienced slight increases in perceptual distortions and anhedonia in seclusion, and these increased further during sensory deprivation. Highly hallucination prone individuals showed a significantly greater increase in perceptual distortions in sensory deprivation than did non-prone individuals suggesting a state-trait interaction. Their appraisals of these anomalous experiences were compared to both clinical and non-clinical individuals experiencing psychotic symptoms in everyday life.Conclusion: Short-term sensory deprivation is a potentially useful paradigm to model psychotic experiences, as it is a non-pharmacological tool for temporarily inducing psychotic-like states and is entirely safe at short duration. Experiences occur more frequently, though not exclusively, in those at putative risk of a psychotic disorder. The appraisals of anomalous experiences arising are largely consistent with previous observations of non-clinical individuals though importantly lacked the general positivity of the latter.

    Long-term field experiments can reveal changes in ecosystem processes that may not be evident in short-term studies. Short-term measurements or experiments may have narrower objectives or unrealistic treatments in order to see a change, whereas long-term studies can reveal complex interactions that take longer to manifest. We report results from a long-term experiment (1996 to present) in subalpine forests to simulate the consequences of sustained atmospheric nitrogen (N) deposition. Loch Vale watershed in Rocky Mountain National Park, the location of the experiment, has received an order of magnitude greater atmospheric N deposition than estimated background since mid-20th Century. Augmenting that, in 1996 we began adding 25 kg NH4NO3 ha-1 yr-1 to three 30m x 30m old-growth Engelmann spruce and subalpine fir plots. Treated stands were matched by nearby controls. N addition caused rapid leaching of nitrate and cations from soils, and increased N mineralization and nitrification rates. These observations in the fertilized plots have been sustained over time. Soluble aluminum concentrations do not differ significantly between fertilized and control plots, but treated soils are now markedly more acidic (pH of 4.7) than original soil and controls (pH of 5.1); further acidification might increase aluminum leaching. Effects on soil carbon were complex, mediated by reductions in total microbial biomass, decreases in arbuscular mychorrizal and saprotropic fungi, and increased potential rates of N enzyme degrading activities. Initial soil C:N of 24 was lower than similar soils in low N deposition stands (C:N of 36). The C:N declined to 22 with treatment. Fertilized plots lost 11% soil C, but the mechanism is unclear. We did not measure changes in C inputs from litter, microbial biomass, or plant uptake, but there was no change in summer CO2 flux, measured in 2003, 2004, and 2014. Leaching of DOC from fertilized plots was elevated throughout the experiment, providing one

    Full Text Available Abstract Background The prevalence and impact of long term conditions continues to rise. Care planning for people with long term conditions has been a policy priority in England for chronic disease management. However, it is not clear how care planning is currently understood, translated and implemented in primary care. This study explores experience of care planning in patients with long term conditions in three areas in England. Methods We conducted semi-structured interviews with 23 predominantly elderly patients with multiple long term conditions. The interviews were designed to explore variations in and emergent experiences of care planning. Qualitative analysis of interview transcripts involved reflexively coding and re-coding data into categories and themes. Results No participants reported experiencing explicit care planning discussions or receiving written documentation setting out a negotiated care plan and they were unfamiliar with the term ‘care planning’. However, most described some components of care planning which occurred over a number of contacts with health care professionals which we term”reactive” care planning. Here, key elements of care planning including goal setting and action planning were rare. Additionally, poor continuity and coordination of care, lack of time in consultations, and patient concerns about what was legitimate to discuss with the doctor were described. Conclusions Amongst this population, elements of care planning were present in their accounts, but a structured, comprehensive process and consequent written record (as outlined in English Department of Health policy was not evident. Further research needs to explore the advantages and disadvantages of different approaches to care planning for different patient groups.

    We investigated music and language processing in a group of early bilinguals who spoke a tone language and a non-tone language (Cantonese and Dutch). We assessed online speech-music processing interactions, that is, interactions that occur when speech and music are processed simultaneously in songs, with a speeded classification task. In this task, participants judged sung pseudowords either musically (based on the direction of the musical interval) or phonologically (based on the identity of the sung vowel). We also assessed longer-term effects of linguistic experience on musical ability, that is, the influence of extensive prior experience with language when processing music. These effects were assessed with a task in which participants had to learn to identify musical intervals and with four pitch-perception tasks. Our hypothesis was that due to their experience in two different languages using lexical versus intonational tone, the early Cantonese-Dutch bilinguals would outperform the Dutch control participants. In online processing, the Cantonese-Dutch bilinguals processed speech and music more holistically than controls. This effect seems to be driven by experience with a tone language, in which integration of segmental and pitch information is fundamental. Regarding longer-term effects of linguistic experience, we found no evidence for a bilingual advantage in either the music-interval learning task or the pitch-perception tasks. Together, these results suggest that being a Cantonese-Dutch bilingual does not have any measurable longer-term effects on pitch and music processing, but does have consequences for how speech and music are processed jointly.

    Health policy documents underscore the need to develop organizational models to optimize the integration of cancer care pathways around patient needs. Still, there is a lack of clarity about the meaning of integrated care as perceived by patients. The purpose of this study is to explore the relationship between the integration of cancer services and patients' experience. We completed a scoping review of the available literature searching PubMed, Embase and Scopus from the earliest date available in each database to February 2013. From 1760 bibliographic records, we identified 30 articles relevant for this analysis. Based on the qualitative conventional content analysis, we defined three integrated care approaches: "individual care provider", "team care providers", "mixed approach", that impact on the following patient experience dimensions: patient satisfaction, quality of life, psychological and physical outcomes, continuity of care and empowerment. This scoping review identifies important aspects of integration from patients' perspective and suggests that policy makers should consider how to best include patients' experience into the patient care pathway. Future perspectives include engaging patients, family members, caregivers and clinicians in an on-going dialogue and have them participate actively in developing, implementing and evaluating policies, services and programmes.

  4. Short-term Retention of Relational Memory in Amnesia Revisited: Accurate Performance Depends on Hippocampal Integrity

    Full Text Available Traditionally, it has been proposed that the hippocampus and adjacent medial temporal lobe cortical structures are selectively critical for long-term declarative memory, which entails memory for inter-item and item-context relationships. Whether the hippocampus might also contribute to short-term retention of relational memory representations has remained controversial. In two experiments, we revisit this question by testing memory for relationships among items embedded in scenes using a standard working memory trial structure in which a sample stimulus is followed by a brief delay and the corresponding test stimulus. In each experimental block, eight trials using different exemplars of the same scene were presented. The exemplars contained the same items but with different spatial relationships among them. By repeating the pictures across trials, any potential contributions of item or scene memory to performance were minimized, and relational memory could be assessed more directly than has been done previously. When test displays were presented, participants indicated whether any of the item-location relationships had changed. Then, regardless of their responses (and whether any item did change its location, participants indicated on a forced-choice test, which item might have moved, guessing if necessary. Amnesic patients were impaired on the change detection test, and were frequently unable to specify the change after having reported correctly that a change had taken place. Comparison participants, by contrast, frequently identified the change even when they failed to report the mismatch, an outcome that speaks to the sensitivity of the change specification measure. These results confirm past reports of hippocampal contributions to short-term retention of relational memory representations, and suggest that the role of the hippocampus in memory has more to do with relational memory requirements than the length of a retention interval.

    BonaRes ("soil as a sustainable resource for the bioeconomy") is conducting to collect data and metadata of agricultural long-term field experiments (LTFE) of Germany. It is funded by the German Federal Ministry of Education and Research (BMBF) under the umbrella of the National Research Strategy BioEconomy 2030. BonaRes consists of ten interdisciplinary research project consortia and the 'BonaRes - Centre for Soil Research'. BonaRes Data Centre is responsible for collecting all LTFE data and regarding metadata into an enterprise database upon higher level of security and visualization of the data and metadata through data portal. In the frame of the BonaRes project, we are compiling an overview of long-term field experiments in Germany that is based on a literature review, the results of the online survey and direct contacts with LTFE operators. Information about research topic, contact person, website, experiment setup and analyzed parameters are collected. Based on the collected LTFE data, an enterprise geodatabase is developed and a GIS-based web-information system about LTFE in Germany is also settled. Various aspects of the LTFE, like experiment type, land-use type, agricultural category and duration of experiment, are presented in thematic maps. This information system is dynamically linked to the database, which means changes in the data directly affect the presentation. An easy data searching option using LTFE name, -location or -operators and the dynamic layer selection ensure a user-friendly web application. Dispersion and visualization of the overlapping LTFE points on the overview map are also challenging and we make it automatized at very zoom level which is also a consistent part of this application. The application provides both, spatial location and meta-information of LTFEs, which is backed-up by an enterprise geodatabase, GIS server for hosting map services and Java script API for web application development.

    2017-11-01

    Full Text Available Energy planning and policy development require an in-depth assessment of energy resources and long-term demand forecast estimates. Pakistan, unfortunately, lacks reliable data on its energy resources as well do not have dependable long-term energy demand forecasts. As a result, the policy makers could not come up with an effective energy policy in the history of the country. Energy demand forecast has attained greatest ever attention in the perspective of growing population and diminishing fossil fuel resources. In this study, Pakistan’s energy demand forecast for electricity, natural gas, oil, coal and LPG across all the sectors of the economy have been undertaken. Three different energy demand forecasting methodologies, i.e., Autoregressive Integrated Moving Average (ARIMA, Holt-Winter and Long-range Energy Alternate Planning (LEAP model were used. The demand forecast estimates of each of these methods were compared using annual energy demand data. The results of this study suggest that ARIMA is more appropriate for energy demand forecasting for Pakistan compared to Holt-Winter model and LEAP model. It is estimated that industrial sector’s demand shall be highest in the year 2035 followed by transport and domestic sectors. The results further suggest that energy fuel mix will change considerably, such that oil will be the most highly consumed energy form (38.16% followed by natural gas (36.57%, electricity (16.22%, coal (7.52% and LPG (1.52% in 2035. In view of higher demand forecast of fossil fuels consumption, this study recommends that government should take the initiative for harnessing renewable energy resources for meeting future energy demand to not only avert huge import bill but also achieving energy security and sustainability in the long run.

    2017-06-01

    Small-Scale Concentrated Solar Power Plants could have a potential market for off-grid applications in rural contexts with limited access to the electrical grid and favorable environmental characteristics. Some Small-Scale plants have already been developed, like the 25-30 kWe Dish-Stirling engine. Other ones are under development as, for example, plants based on Parabolic Trough Collectors coupled with Organic Rankine Cycles. Furthermore, the technological progress achieved in the development of new small high-temperature solar receiver, makes possible the development of interesting systems based on Micro Gas Turbines coupled with Dish collectors. Such systems could have several advantages in terms of costs, reliability and availability if compared with Dish-Stirling plants. In addition, Dish-Micro Gas Turbine systems are expected to have higher performance than Solar Organic Rankine Cycle plants. The present work focuses the attention on some challenging aspects related to the design of small high-temperature solar receivers for Dish-Micro Gas Turbine systems. Natural fluctuations in the solar radiation can reduce system performance and damage seriously the Micro Gas Turbine. To stabilize the system operation, the solar receiver has to assure a proper thermal inertia. Therefore, a solar receiver integrated with a short-term storage system based on high-temperature phase-change materials is proposed in this paper. Steady-state and transient analyses (for thermal storage charge and discharge phases) have been carried out using the commercial CFD code Ansys-Fluent. Results are presented and discussed.

    Full Text Available Spirogyra africana (Fritsch Czurda is a ubiquitous filamentous green alga that grows naturally in Andalusian farm ponds. Research on this macroalga has reported several biotechnological applications, emphasizing its value for biofuel production. However, culture media for growth of this species have not yet been tested for long-term experiments and stock maintenance. Here we test the three most common culture media cited in the literature for Spirogyra growth, i.e. HSCHU#10, sD11 and pond water, in a 10-week laboratory experiment. We compared growth rates, percentages of live filaments and number of rhizoids per filament of S. africana cultured in each medium. The effect of filament sterilization to obtain monoalgal cultures, i.e. chlorination, was also tested on its growth. After 10 weeks, S. africana grew in HSCHU#10, whilst FPW and sD11 showed poorer results. Filament chlorination prior to inoculation showed a positive effect on growth, especially several weeks after algal inoculation. Rhizoid genesis seemed to be dependent on additional external factors, but responded to chlorination positively. We recommend the use of HSCHU#10 and the surface decontamination of filamentous algae with chlorine for Spirogyra cultures, especially for long-term experiments and stock maintenance.

    There is inconclusive evidence on the value of regular dental attendance. This study explored the relationship between long-term patterns of dental attendance and caries experience. We used retrospective data from 3,235 adults, ≥ 16 yrs of age, who participated in the Adult Dental Health Survey in the UK. Participants were classified into four groups (always, current, former, and never regular-attenders) based on their responses to three questions on lifetime dental-attendance patterns. The association between dental-attendance patterns and caries experience, as measured using the decayed, missing, or filled teeth (DMFT) index, was tested in negative binomial regression models, adjusting for demographic (sex, age, and country of residence) and socio-economic (educational attainment, household income, and social class) factors. A consistent pattern of association between long-term dental attendance and caries experience was found in adjusted models. Former and never regular-attenders had a significantly higher DMFT score and numbers of decayed and missing teeth, but fewer filled teeth, than always regular-attenders. No differences in DMFT or its components were found between current and always regular-attenders. The findings of this study show that adults with different lifetime trajectories of dental attendance had different dental statuses. © 2014 Eur J Oral Sci.

    Workplace support is an important factor in promoting successful return to work. The purpose of this article is to examine relationships between supervisor contact, perceived workplace support and demographic variables among employees on long-term sickness absence. Data were collected from 204 public employees at a municipality in Sweden who had been on long term sickness absence (60 days or more) using a 23 question survey instrument that collected information on demographic variables, supervisor contact and perceived workplace support. Most injured employees (97%) reported having contact with their supervisors during their sickness absence, with a majority (56%) reporting high levels of support, including early (58.6%) and multiple (70.7%) contacts. Most were pleased with amount of contact (68.9%) and the majority had discussed workplace accommodations (68.1%). Employees who self-initiated contact, felt the amount of contact was appropriate, had a personal meeting with their supervisors and discussed workplace adjustments reported experiencing higher levels of support from supervisors. Employees on long-term sickness absence appreciate contact from their supervisors and this is associated with perceived workplace support. However, the amount and employee experience of this contact is important. It needs to be perceived by employees as supportive, which includes a focus on strategies (e.g., work adjustment) to facilitate a return to work. Supervisor training is required in this area to support the return to work process. Implications for Rehabilitation Contact and support from workplace supervisors is important to workers on long-term sickness absence. Employees appreciate frequent contact from supervisors during long-terms sickness absence. Employees appreciate a personal meeting with supervisors and the opportunity to discuss issues related to return to work such as work adjustment. Employers should provide training to supervisors on how to communicate and

Although the underlying etiology of SPD is unknown, one brain region likely to reflect these sensory and behavioral anomalies is the Superior Colliculus (SC; a structure involved in the synthesis of information from multiple sensory modalities and the control of overt orientation responses. In this review we describe normal functional properties of this structure, the manner in which its individual neurons integrate cues from different senses, and the overt SC-mediated behaviors that are believed to manifest this “multisensory integration.” Of particular interest here is how SC neurons develop their capacity to engage in multisensory integration during early postnatal life as a consequence of early sensory experience, and that it is the intimate communication between cortex and the midbrain makes this developmental process possible.

    Meeting production targets in terms of ore quantity and quality is critical for a successful mining operation. In-situ grade uncertainty causes both deviations from production targets and general financial deficits. A new stochastic optimization algorithm based on ant colony optimization (ACO) approach is developed herein to integrate geological uncertainty described through a series of the simulated ore bodies. Two different strategies were developed based on a single predefined probability value (Prob) and multiple probability values (Pro bnt) , respectively in order to improve the initial solutions that created by deterministic ACO procedure. Application at the Sungun copper mine in the northwest of Iran demonstrate the abilities of the stochastic approach to create a single schedule and control the risk of deviating from production targets over time and also increase the project value. A comparison between two strategies and traditional approach illustrates that the multiple probability strategy is able to produce better schedules, however, the single predefined probability is more practical in projects requiring of high flexibility degree.

  7. Estimating long-term behavior of periodically driven flows without trajectory integration

    Periodically driven flows are fundamental models of chaotic behavior and the study of their transport properties is an active area of research. A well-known analytic construction is the augmentation of phase space with an additional time dimension; in this augmented space, the flow becomes autonomous or time-independent. We prove several results concerning the connections between the original time-periodic representation and the time-extended representation, focusing on transport properties. In the deterministic setting, these include single-period outflows and time-asymptotic escape rates from time-parameterized families of sets. We also consider stochastic differential equations with time-periodic advection term. In this stochastic setting one has a time-periodic generator (the differential operator given by the right-hand-side of the corresponding time-periodic Fokker–Planck equation). We define in a natural way an autonomous generator corresponding to the flow on time-extended phase space. We prove relationships between these two generator representations and use these to quantify decay rates of observables and to determine time-periodic families of sets with slow escape rate. Finally, we use the generator on the time-extended phase space to create efficient numerical schemes to implement the various theoretical constructions. These ideas build on the work of Froyland et al (2013 SIAM J. Numer. Anal. 51 223–47), and no expensive time integration is required. We introduce an efficient new hybrid approach, which treats the space and time dimensions separately.

  8. Toward a theory of multilevel evolution: long-term information integration shapes the mutational landscape and enhances evolvability.

    2012-01-01

    Most of evolutionary theory has abstracted away from how information is coded in the genome and how this information is transformed into traits on which selection takes place. While in the earliest stages of biological evolution, in the RNA world, the mapping from the genotype into function was largely predefined by the physical-chemical properties of the evolving entities (RNA replicators, e.g. from sequence to folded structure and catalytic sites), in present-day organisms, the mapping itself is the result of evolution. I will review results of several in silico evolutionary studies which examine the consequences of evolving the genetic coding, and the ways this information is transformed, while adapting to prevailing environments. Such multilevel evolution leads to long-term information integration. Through genome, network, and dynamical structuring, the occurrence and/or effect of random mutations becomes nonrandom, and facilitates rapid adaptation. This is what does happen in the in silico experiments. Is it also what did happen in biological evolution? I will discuss some data that suggest that it did. In any case, these results provide us with novel search images to tackle the wealth of biological data.

    Action video games (AVGs) have attracted increasing research attention as they offer a unique perspective into the relation between active learning and neural plasticity. However, little research has examined the relation between AVG experience and the plasticity of neural network mechanisms. It has been proposed that AVG experience is related to the integration between Salience Network (SN) and Central Executive Network (CEN), which are responsible for attention and working memory, respectively, two cognitive functions essential for AVG playing. This study initiated a systematic investigation of this proposition by analyzing AVG experts' and amateurs' resting-state brain functions through graph theoretical analyses and functional connectivity. Results reveal enhanced intra- and internetwork functional integrations in AVG experts compared to amateurs. The findings support the possible relation between AVG experience and the neural network plasticity.

    Full Text Available Social transformations have raised reflection about the paternal role and pointed to new fatherhoods, characterized by more effective involvement of the father in the family routine and in childcare. The present integrative review of qualitative studies aimed to synthetize the literature evidence about fatherhood experience throughout the first year of the child’s life, attentive to gender questions. Twenty three studies integrated this review. It was observed that fathers had positive experience with their babies and, still, craved for more time and space to dedicate to the family. However, inequality between genders, continuous requirement of financial provision at home and their inaptitude for breastfeeding moment impeded more paternal involvement. We concluded that new fatherhoods movement is present in the father experience and contemporary gender tendencies are challenges for parenting support.

    2001-01-01

    Researchers at the NASA Glenn Research Center have developed a prototype integrated environment for interactively exploring, analyzing, and validating information from computational fluid dynamics (CFD) computations and experiments. The Integrated CFD and Experiments (ICE) project is a first attempt at providing a researcher with a common user interface for control, manipulation, analysis, and data storage for both experiments and simulation. ICE can be used as a live, on-tine system that displays and archives data as they are gathered; as a postprocessing system for dataset manipulation and analysis; and as a control interface or "steering mechanism" for simulation codes while visualizing the results. Although the full capabilities of ICE have not been completely demonstrated, this report documents the current system. Various applications of ICE are discussed: a low-speed compressor, a supersonic inlet, real-time data visualization, and a parallel-processing simulation code interface. A detailed data model for the compressor application is included in the appendix.

    The transport of uranium dioxide (UO/sub 2/) aerosol through liquid sodium was studied in a series of ten experiments in the Fuel Aerosol Simulant Test (FAST) facility at Oak Ridge National Laboratory (ORNL). The experiments were designed to provide a mechanistic basis for evaluating the radiological source term associated with a postulated, energetic core disruptive accident (CDA) in a liquid metal fast breeder reactor (LMFBR). Aerosol was generated by capacitor discharge vaporization of UO/sub 2/ pellets which were submerged in a sodium pool under an argon cover gas. Measurements of the pool and cover gas pressures were used to study the transport of aerosol contained by vapor bubbles within the pool. Samples of cover gas were filtered to determine the quantity of aerosol released from the pool. The depth at which the aerosol was generated was found to be the most critical parameter affecting release. The largest release was observed in the baseline experiment where the sample was vaporized above the sodium pool. In the nine ''undersodium'' experiments aerosol was generated beneath the surface of the pool at depths varying from 30 to 1060 mm. The mass of aerosol released from the pool was found to be a very small fraction of the original specimen. It appears that the bulk of aerosol was contained by bubbles which collapsed within the pool. 18 refs., 11 figs., 4 tabs.

    Education and Public Outreach (E/PO) targeting pre-college education can be focused on teachers or students, but is ultimately only effective if it impacts classrooms. A challenge in the teacher workshop model is tracking the impact we have actually made. Teachers may be excited by our offerings, and rate workshops highly, but is our E/PO actually making a difference with pre-college students? In June 2005 we ran our second four-day teacher workshop for the joint NASA/U.S. Air Force sponsored ionospheric instrument package, the Coupled Ion Neutral Dynamics Investigation (CINDI) with a new twist. We experimented with the integration of our workshop into a long-term professional development program for 6th and 7th grade teachers at UT Dallas. Immediate direct benefits to the CINDI E/PO program included knowledge of teacher backgrounds prior to the workshop, a narrow target grade level range, and the elimination of the need for separate recruiting efforts. More importantly, by working within a year-long program supported by a Teacher Quality Grant we have been able to better assess teacher learning and the impact our outreach efforts is having on the middle school students of participants. The 20-contact hours our workshop contributed to the Teacher Quality Summer Institute were specifically designed to meet Texas standards for middle school science, and made connections between space weather, Earth systems, basic physics, technology, and communications. Participants were able to interact with members of the science team in formal settings and over casual lunches. We will present our motivations for this experiment, participant feedback, and lessons learned. In addition, we will give an update on our CINDI Educator Guide, and the newly completed Cindi in Space comic book.

    Full Text Available Starting from Nineties, many experiences, focused on the integration between urban and territorial transformation government and mobility management and aimed at achieving objectives of sustainability, have been carried out in different European cities. In these experiences, the integration between urban transformation government and mobility management has been tested at different scales and with different approaches. In detail, such an integration is pursued both through the definition of the dimension, localization and spatial and functional features of new settlements, both through the requalification of the existing ones by the improvement of transport infrastructures, the public space design, the location of activities connected to the public transport network, the traffic flows regulation. With reference to such experiences, the paper outlines a synthetic view of different case-studies focused on the most recent integrated policies referred to the territorial transformation government and to the mobility management. Then, the most significant weaknesses and the more innovative aspects of some case-studies are highlighted both for the new settlements and for the existing ones.

    2012-12-01

    Full Text Available Throughout the nervous system, neurons integrate high-dimensional input streams and transform them into an output of their own. This integration of incoming signals involves filtering processes and complex nonlinear operations. The shapes of these filters and nonlinearities determine the computational features of single neurons and their functional roles within larger networks. A detailed characterization of signal integration is thus a central ingredient to understanding information processing in neural circuits. Conventional methods for measuring single-neuron response properties, such as reverse correlation, however, are often limited by the implicit assumption that stimulus integration occurs in a linear fashion. Here, we review a conceptual and experimental alternative that is based on exploring the space of those sensory stimuli that result in the same neural output. As demonstrated by recent results in the auditory and visual system, such iso-response stimuli can be used to identify the nonlinearities relevant for stimulus integration, disentangle subsequent neural processing steps, and determine their characteristics with unprecedented precision. Automated closed-loop experiments are crucial for this advance, allowing rapid search strategies for identifying iso-response stimuli during experiments. Prime targets for the method are feed-forward neural signaling chains in sensory systems, but the method has also been successfully applied to feedback systems. Depending on the specific question, iso-response may refer to a predefined firing rate, single-spike probability, first-spike latency, or other output measures. Examples from different studies show that substantial progress in understanding neural dynamics and coding can be achieved once rapid online data analysis and stimulus generation, adaptive sampling, and computational modelling are tightly integrated into experiments.

    TeleseTerme plain is characterized by a very articulated stratigraphy (levels of travertine, fluvial-marshy and pyroclastic deposits), that allows the occurrence of underground water circulation with overlapping aquifers. These aquifers are locally in pressure and, because of chemical characteristics and physical properties of the water, they may activate processes of accelerated travertine's corrosion; the consequence is the formation of cavity along the ground water's preferential flow paths, and the activation of subsidence and sinkholes phenomena. In particular test area includes two zones, where in 2002 and 2006 occurred two sinkholes events, classified as "piping sinkholes". The hazard evaluation was carried out trhought an integrated monitoring system, based on "traditional" techniques conduced "in situ", as geological-geomorphological and geophysical (microgravity) surveys, integrated by the most innovative techniques of Remote sensing interferometry(Advanced DInSAR Interferometry Techniques). The last allow to evaluate the ground deformation, characterized by a predominantvertical component (typical deformation of sinkholes and subsidence phenomena), and are well suited to operate a continuous and long monitoring ofvery extended areas. Through an initial analysis of the Permanent Scatterers available in the Telese municipality, we found the envelopes of the areal that contain PS with negative and positive mean velocities; these velocities showed the presence of a possible phenomenon of subsidence detected by ERS and ENVISAT satellites. Through interferometric processing of ENVISAT images, the soil deformations of 2002-2010 year sare evaluated and compared with the data obtainedby survey took "in situ" during the same period. The knowledge of the deformation's evolution of the area made it possible to organize a more focused future monitoring through traditional techniques of relief (with the help of geophysical methodologies).

    Histopathological analysis can provide important information in long-term experiments with total artificial heart (TAH). Recently, a new type of blood pump, the helical flow total artificial heart (HF-TAH) was developed. This study aimed to investigate the changes in selected vital organs in animal experiments with implanted HF-TAH. Samples from lung, liver, and kidneys from two female goats (No. 1301 and No. 1304) with implanted HF-TAH were analyzed. Tissue samples were fixed in 10% formaldehyde and 4 µm thick transverse sections were stained with hematoxylin-eosin (HE). Additional staining was done for detection of connective tissue (Masson-Goldner stain) and for detection of iron (hemosiderin) deposits (Perls stain). Sections were scanned at 100× and 500× magnification with a light microscope. Experiment no. 1301 survived 100 days (cause of termination was heavy damage of the right pump); experimental goat no.1304 survived 68 days and was sacrificed due to severe right hydrodynamic bearing malfunction. Histopathological analysis of liver samples proved signs of chronic venostasis with limited focal necrotic zones. Dilated tubules, proteinaceous material in tubular lumen, and hemosiderin deposits were detected in kidney samples. Contamination of the organs by embolized micro-particles was suspected at the autopsy after discovery of visible damage (scratches) of the pump impeller surface (made from titanium alloy) in both experiments. Sporadic deposits of foreign micro-particles (presumably titanium) were observed in most of the analyzed parenchymal organs. However, the described deposits were not in direct connection with inflammatory reactions in the analyzed tissues. Histopathological analysis showed the presence of minimal contamination of the lung, kidney, and liver tissue samples by foreign material (titanium very likely). The analysis showed only limited pathological changes, especially in liver and kidneys, which might be attributed to the influence of

  8. SOIL AGROCHEMICAL PROPERTIES IMPROVEMENT IN LONG TERM FIELD EXPERIMENT WITH FERTILIZERS

    Full Text Available Soil fertility is studied in long-term field experiments. Researches are carried out in several agricultural research stations, out of which the following have been chosen for the present paper: Albic Luvisol* at Albota; Haplic Phaeozem at Fundulea; Chromic Luvisol at Şimnic; Calcic Chernozem at Secuieni; and Haplic Chernozem at Podu Iloaiei. Long term fertilization with nitrogen and phosphorus generally improved the soil agrochemical properties. The evolution of organic matter, nitrogen, mobile phosphorus and potassium, and mobile microelements contents were studied, using the standardized method used in the ICPA laboratories. The organic matter and total nitrogen contents didn’t change significantly under the nitrogen and phosphorus long-term fertilization influence. The mobile phosphorus contents have the tendency to grow very significantly with the growth of phosphorus fertilizers. At the same time, slight depletions of these contents are registered as the high nitrogen doses from fertilizers stimulate plant growth and, obviously, nutritive elements absorption. Mobile potassium contents changes very little, with insignificant differences. Significant depletions are registered only with high fertilizers doses, due to the stimulation of the nutritive elements absorption in plants. Microelements contents don’t change almost at all. They are within the normal content limits and no excess or deficiency was registered, in any of the studied stations. For the agricultural practice, economical studies are recommended, about how high fertilizing expenses are covered by the yield growth. Not the least, production quality study in different variants of mineral fertilization could prove interesting.

  9. Combining long term field experiments and nanoscale analysis to enhance process understanding of root litter stabilization by mineral interactions

    Mineral interaction may affect the stabilisation of root litter directly or indirectly after microbial decomposition and transformation. The importance of both processes may vary within the soil profile. In this study we studied C stabilisation of isotopically labelled root litter (13C and 15N), which was incubated during 3 year in the field at different soil depth. Samples from this field experiment were recovered and subjected to nanoscale analyses in order to elucidate mineral interactions occurring in different parts of the soil profile. Our results showed enrichment of mineral associated organic matter in subsoil horizons. However, material derived from new plant litter may be stabilised at similar rates in top- and subsoil horizons. N-containing compounds are enriched in the mineral associated fraction of subsoil horizons, indicating enrichment of microbial derived material with depth. Nano scale analyses showed that indeed plant-derived material may be associated with metal oxides in topsoil horizons, whereas the mineral associated organic matter in subsoil horizons may consist of microbial cells. Interestingly, in contrast to short term laboratory analysis, decoupling of C and N through stabilisation with soil minerals was observed during this long term field experiment. Our results indicate that the nature of OM stabilised by mineral interactions is depth specific. Therefore, we suggest, that plant derived lignocellulosic material may be preserved by mineral interactions in topsoil given its incomplete degradation, thereby leading to the formation of functional groups and favouring adsorption to soil minerals. This is consistent with the higher state of lignin-degradation observed in topsoil horizons as compared to subsoil. At depth, where microorganisms are most likely energy limited, degradation of fresh plant litter may be complete, thereby diminishing the formation of lignocellulosic compounds capable of sorption onto metal oxides. As a result

    2007-08-31

    The purpose of this project is to formulate a 'Supercement' designed for improving the long-term sealing integrity in HPHT wells. Phase I concentrated on chemistry studies and screening tests to design and evaluate Portland-based, hybrid Portland, and non-Portland-based cement systems suitable for further scale-up testing. Phase II work concentrated on additional lab and field testing to reduce the candidate materials list to two systems, as well as scaleup activities aimed at verifying performance at the field scale. Phase II was extended thorough a proposal to develop additional testing capabilities aimed at quantifying cementing material properties and performance that were previously not possible. Phase III focused on bringing the material(s) developed in previous Phases to commercialization, through Field Trials, Cost/Benefit Analysis, and Technology Transfer. Extensive development and testing work throughout the project led to Phase III commercialization of two very different materials: (1) Highly-expansive cement (Portland-based), patent pending as 'PRESTRESSED CEMENT'; and (2) Epoxy Resin (non-Portland-based), patent pending. Trade name is Ultra Seal-R. In Phase III, work concentrated on application of the Supercement materials in various increasingly-challenging wells. Previous testing revealed that PRESTRESSED CEMENT, when applied in weak or unconsolidated formations, tends to expand away from the central pipe, restricting the applicability of this material to competent formations. Tests were devised to quantify this effect so the material could be applied in appropriate wells. Additionally, the testing was needed because of industry resistance to expansive cements, due to previous marketing attempts with other materials that were less than successful. Field trials with the Epoxy Resin currently numbers in the hundreds of jobs at up to 295 deg F, with a large percentage being completely successful. Both the PRESTRESSED CEMENT as well

    The purpose of this project is to formulate a ''Supercement'' designed for improving the long-term sealing integrity in HPHT wells. Phase I concentrated on chemistry studies and screening tests to design and evaluate Portland-based, hybrid Portland, and non-Portland-based cement systems suitable for further scale-up testing. Phase II work concentrated on additional lab and field testing to reduce the candidate materials list to two systems, as well as scale up activities aimed at verifying performance at the field scale. Phase II was extended thorough a proposal to develop additional testing capabilities aimed at quantifying cementing material properties and performance that were previously not possible. Two materials are being taken into Phase III for field testing and commercialization: {lg_bullet} Highly-expansive cement (Portland-based), patent pending as ''Pre-Stressed Cement'' {lg_bullet} Epoxy Resin (non-Portland-based), patent pending In Phase II, significant effort was expended on scaling up the processes for handling resin in the field, as it is quite different than conventional Portland-based cements in mixing, personnel protection, and cleanup. Through this effort, over fifty (50) field jobs were done at a variety of temperatures and depths, most with excellent results. Large-scale field testing was less relevant with Pre-stressed Cement, because the materials and surface processes do not vary from those that have been developed for conventional Portland materials over the last eighty (80) years. The formulation is quite unique, however, and performs very differently than conventional Portland cements downhole.

  12. Long-term climate sensitivity of an integrated water supply system: The role of irrigation.

    2016-09-15

    The assessment of the impact of long-term climate variability on water supply systems depends not only on possible variations of the resources availability, but also on the variation of the demand. In this framework, a robust estimation of direct (climate induced) and indirect (anthropogenically induced) effects of climate change is mandatory to design mitigation measures, especially in those regions of the planet where the groundwater equilibrium is strongly perturbed by exploitations for irrigation purposes. The main goal of this contribution is to propose a comprehensive model that integrates distributed crop water requirements with surface and groundwater mass balance, able to consider management rules of the water supply system. The proposed overall model, implemented, calibrated and validated for the case study of the Fortore water supply system (Apulia region, South Italy), permits to simulate the conjunctive use of the water from a surface artificial reservoir and from groundwater. The relative contributions of groundwater recharges and withdrawals to the aquifer stress have been evaluated under different climate perturbations, with emphasis on irrigation practices. Results point out that irrigated agriculture primarily affects groundwater discharge, indicating that ecosystem services connected to river base flow are particularly exposed to climate variation in irrigated areas. Moreover, findings show that the recharge both to surface and to groundwater is mainly affected by drier climate conditions, while hotter conditions have a major impact on the water demand. The non-linearity arising from combined drier and hotter conditions may exacerbate the aquifer stress by exposing it to massive sea-water intrusion. Copyright © 2016 Elsevier B.V.

    In blood serum of 9 volunteers aged 27 to 42, participated in the experiment with 370-day antiorthostatic hypokinesia (-5 degrees), the lipid peroxidation derivates concentration--diene conjugates (DC), malonic dialdehyde (MDA), Schiff bases (SB) as well as antioxidant defense system indices--tocopherol (TP) concentration and total antioxidative activity level (AOA) were measured. The volunteers were divided into two groups subjected to physical training regimes and used prophylactic measures. In both groups the lipoperoxidation processes initial stages depression (by 54-73%) was observed starting from 50th day, thus the lipid peroxidation final product--SB level was decreased (by 50-61%) only to the 230 day and remains approximately at the same level till the end of the experiment. The restorative period was characterized by decreasing (in 1.6-2.3 times) of MDA and SB concentrations. The decrease in lotal AOA during the aftereffect period was detected in all volunteers, and its level was significantly lower physiological norm range. Probably, long-term adaptation to the simulated weightlessness conditions is accompanied by expressed decrease in biological oxidation processes intensity and significant stress effect, as indicates by essential depression of lipid free radical oxidation in the course of the experiment. At the same time the restorative period after 370-day antiorthostatic hypokinesia was characterized by significantly expressed and prolonged readaptation stress progress. It is evidenced by practically twofold decrease in lipoperoxidation processes intensity against significant increase in TP concentration and water-soluble antioxidants functional reserves exhaustion. Lipid peroxidation activation absence in all terms of examination reflects appropriate compensation of studying impact by volunteers.

    2017-01-01

    We compared the results of a long-term (65 years) experiment in a South African grassland with the world's longest-running ecological experiment, the Park Grass study at Rothamsted, U.K. The climate is warm and humid in South Africa and cool and temperate in England. The African grassland has been fertilized with two forms of nitrogen applied at four levels, phosphorus and lime in a crossed design in 96 plots. In 1951, about 84% of plant cover consisted of Themeda triandra, Tristachya leucothrix and Setaria nigrirostris. Currently, the dominant species are Panicum maximum, Setaria sphacelata and Eragrostis curvula, making up 71% of total biomass. As in the Park Grass experiment, we found a significant (additive) interaction effect on ANPP of nitrogen and phosphorus, and a (marginally significant) negative correlation between ANPP and species richness. Unlike the Park Grass experiment, there was no correlation between ANPP and species richness when pH was included as a covariate. There was also a significant negative effect of nitrogen amount and nitrogen form and a positive effect of lime on species richness and species diversity. Soil pH had an important effect on species richness. Liming was insufficient to balance the negative effects on species richness of nitrogen fertilization. There was a significant effect of pH on biomass of three abundant species. There were also significant effects of light on the biomass of four species, with only Panicum maximum having a negative response to light. In all of the abundant species, adding total species richness and ANPP to the model increased the amount of variance explained. The biomass of Eragrostis curvula and P. maximum were negatively correlated with species richness while three other abundant species increased with species richness, suggesting that competition and facilitation were active. Consistent with the results from the Park Grass and other long-term fertilization experiments of grasslands, we found a

    We perform the integration of all iterated singly-unresolved subtraction terms over the two-particle factorized phase space. We also sum over the unresolved parton flavours. The final result can be written as a convolution (in colour space) of the Born cross section and an insertion operator. We spell out the insertion operator in terms of 24 basic integrals that are defined explicitly. We compute the coefficients of the Laurent-expansion of these integrals in two different ways, with the method of Mellin-Barnes representations and sector decomposition. Finally, we present the Laurentexpansion of the full insertion operator for the specific examples of electron-positron annihilation into two and three jets. (orig.)

    We carried our examination in a long-term fertilization field experiment in 2005. In the experiment we had opportunity to compare the weediness in NPK and NPK + FYM1 treatments, and we could study the effect of increasing N dosis on the weeds and maize. The bi-factorial trial was arranged in split plot design with three replications. The weed survey was made 25 days after seeding in the 27th of may. For the weed survey the Balázs-Ujvárosi method was applied. After the weed survey we collected all the weed species from the plots per 1-1 m2. We counted, mesured the fresh and dry matter weight of aerial shoots. We collected maize too, five pieces per plots. In the experiment were found 12 weed species, 9 annual: Abutilon theophrasti, Amaranthus chlorostachys, Ambrosia artemisiifolia, Chenopodium album, Chenopodium hybridum, Echinochloa crus-galli, Polygonum lapathifolium, Xantium strumarium, Veronica hederi-folia, and 3 perennial: Cirsium arvense, Convolvulus arvensis, Lathyrus tuberosus. On the NPK plots the Ch. album, on NPK + FYM treatments the A. theophrasti was the first in order of the dominance. The biomass production of weeds in the NPK + FYM treatments were 3 times higher than in the only NPK treatments.

    An open issue still under investigation by several international entities working on the safety and security field for the foreseen nuclear fusion reactors is the estimation of source terms that are a hazard for the operators and public, and for the machine itself in terms of efficiency and integrity in case of severe accident scenarios. Source term estimation is a crucial key safety issue to be addressed in the future reactors safety assessments, and the estimates available at the time are not sufficiently satisfactory. The lack of neutronic data along with the insufficiently accurate methodologies used until now, calls for an integrated methodology for source term estimation that can provide predictions with an adequate accuracy. This work proposes a complete methodology to estimate dust source terms starting from a broad information gathering. The wide number of parameters that can influence dust source term production is reduced with statistical tools using a combination of screening, sensitivity analysis, and uncertainty analysis. Finally, a preliminary and simplified methodology for dust source term production prediction for future devices is presented.

    LHCb's Experiment Control System will handle the configuration, monitoring, and operation of all experimental equipment involved in the various activities of the experiment. A control framework (based on an industrial SCADA system) allowing the integration of the various devices into a coherent hierarchical system is being developed in common for the four Large Hadron Collider (LHC) experiments. The aim of this paper is to demonstrate that the same architecture and tools can be used to control and monitor all the different types of devices, from front-end electronics boards to temperature sensors to algorithms in an event filter farm, thus providing LHCb with a homogeneous control system and a coherent interface to all parts of the experiment. 9 Refs.

    Full Text Available The travel industry in Hawaii has been experiencing a trend towards more authentic tourism, which reintegrates Hawaiian culture into the visitors’ experience. This study investigated the reintegration of Hawaiian culture into the tourism experience on the Hawaiian Islands by reviewing existing literature, and by analyzing primary data collected through visitor surveys. The purpose of the study was to determine whether there is a visitors’ demand for a more authentic tourism experience in Hawaii through the reintegration of Hawaiian culture, and if so, which efforts should be made or continue to be made to achieve this authenticity. Important aspects that were taken into consideration in this research effort arethe changes Hawaiian culture has experienced with the arrival of outsiders, and the authenticity of the Hawaiian tourism experience today. Further aspects that were examined include the visitors’ image of Hawaii, their expectations, their experiences and satisfaction during their stay, their interest in and understanding of Hawaiian culture, as well as the type of Hawaiian cultural experiences they are interested in. According to the findings of this study, English speaking visitors are interested in Hawaiian culture and feel that Hawaiian culture is not represented enough in the tourism experience today. The conclusion is, therefore, that efforts to integrate Hawaiian culture into the tourism experience need to be increasedbeyond what is currently being done. Ideas for reintegrating Hawaiian culture are discussed and possible solutions are provided.

    2008-01-01

    The ST5 technology demonstration mission led by GSFC of NASA's New Millennium Program managed by JPL consisted of three micro satellites (approximately 30 kg each) deployed into orbit from the Pegasus XL launch vehicle. In order to meet the launch date schedule of ST5, a different approach was required rather than the standard I&T approach used for single, room-sized satellites. The three spacecraft were designed, integrated, and tested at NASA Goddard Space Flight Center. It was determined that there was insufficient time in the schedule to perform three spacecraft I&T activities in series using standard approaches. The solution was for spacecraft #1 to undergo integration and test first, followed by spacecraft #2 and #3 simultaneously. This simultaneous integration was successful for several reasons. Each spacecraft had a Lead Test Conductor who planned and coordinated their spacecraft through its integration and test activities. One team of engineers and technicians executed the integration of all three spacecraft, learning and gaining knowledge and efficiency as spacecraft #1 integration and testing progressed. They became acutely familiar with the hardware, operation and processes for I&T, thus had the experience and knowledge to safely execute I&T for spacecraft #2 and #3. The integration team was extremely versatile; each member could perform many different activities or work any spacecraft, when needed. ST5 was successfully integrated, tested and shipped to the launch site per the I&T schedule that was planned three years previously. The I&T campaign was completed with ST5's successful launch on March 22, 2006.

    The Integrable Optics Test Accelerator (IOTA) storage ring at Fermilab will serve as the backbone for a broad spectrum of Advanced Accelerator R&D (AARD) experiments, and as such, must be designed with signi cant exibility in mind, but without compromising cost e ciency. The nonlinear experiments at IOTA will include: achievement of a large nonlinear tune shift/spread without degradation of dynamic aperture; suppression of strong lattice resonances; study of stability of nonlinear systems to perturbations; and studies of di erent variants of nonlinear magnet design. The ring optics control has challenging requirements that reach or exceed the present state of the art. The development of a complete self-consistent design of the IOTA ring optics, meeting the demands of all planned AARD experiments, is presented. Of particular interest are the precise control for nonlinear integrable optics experiments and the transverse-to-longitudinal coupling and phase stability for the Optical Stochastic Cooling Experiment (OSC). Since the beam time-of- ight must be tightly controlled in the OSC section, studies of second order corrections in this section are presented.

    This paper identifies the lessons to be learned for the institutionalization of Safeguards by Design (SBD) from the Department of Energy (DOE) experience developing and implementing DOE-STD-1189-2008, Integration of Safety into the Design Process. The experience is valuable because of the similarity of the challenges of integrating safety and safeguards into the design process. The paper reviews the content and development of DOE-STD-1189-2008 from its initial concept in January 2006 to its issuance in March 2008. Lessons learned are identified in the areas of the development and structure of requirements for the SBD process; the target audience for SBD requirements and guidance, the need for a graded approach to SBD, and a possible strategy for development and implementation of SBD within DOE.

    The spaceflight orthostatic challenge can promote in astronauts inadequate cardiovascular responses defined as cardiovascular deconditioning. In particular, disturbance of endothelial functions are known to lead to altered vascular performances, being the endothelial cells crucial in the maintenance of the functional integrity of the vascular wall. In order to evaluate whether weightlessness affects endothelial functions, we designed, developed, and performed the experiment SPHINX - SPaceflight of HUVEC: an INtegrated eXperiment - where HUVEC (Human Umbilical Vein Endothelial Cells) were selected as a macrovascular cell model system. SPHINX arrived at the International Space Station (ISS) onboard Progress 40P, and was processed inside Kubik 6 incubator for 7 days. At the end, all of the samples were suitably fixed and preserved at 6°C until return on Earth on Soyuz 23S.

  17. Long-term leaching mechanisms of ashes and slags; Combining laboratory experiments with computer simulations

    Energy Technology Data Exchange (ETDEWEB)

    Baeverman, C.

    1997-12-31

    The leaching properties of slags and ashes have been studied on four waste materials: municipal solid waste incineration, MSWI, bottom ash, wood ash, electric arc furnace slag and blast furnace slag. The aim of the study has been to investigate properties that influence the long-term leaching of these materials. The results of the laboratory experiments have been used in computer simulations using CHEMFRONTS. CHEMFRONTS is a coupled geochemical and transport computer program developed by the author within this work. The main variable influencing the leaching of metal from solid waste is the final pH of the solution. This can be controlled by several factors, but if the contact time between the water and the waste material is sufficient, the waste itself often controls the pH by buffering reactions. The buffering capacity of a material is, therefore, one of the most important factors to investigate when the long-term leaching behaviour is to be predicted. A pH titration curve has been made for each material within this work, using a pH batch experimental series. The change in pH with time has also been studied. The materials have been studied by X-ray diffraction analysis and Scanning Electron Microscopy / Energy Dispersive Spectroscopy to assess the mineralogy and morphology of the materials. The mineralogy is important for computer simulations. A number of leaching experiments have been performed. A batch flow-through method has been developed which is a serial batch experiment, in which the contact time can be controlled. This technique makes it possible to have oxygen access in all the {sup c}olumns{sup ,} to simulate partly saturated conditions. Sampling is also possible in the {sup c}olumns{sup .} The influence of particle size has been studied, and surprisingly no influence of the particle size could be noted after 24 hours of leaching. The substitution of sand in concrete with steel slag has been studied by both physical and chemical tests. The steel slag

    We report our experience in pediatric renal transplantation avoiding steroids whenever possible. Immunosuppression consisted of an initial induction with antithymocyte globulin followed by maintenance therapy with a calcineurin inhibitor and MMF. Steroids were only given to selected patients......). Unfortunately PTLD occurred in three patients, but all survived with functioning grafts. Accordingly, our findings indicate that steroid avoidance in pediatric renal transplantation is possible with good results with respect to acute graft rejection as well as long-term graft survival....... because of the primary disease, recurrence, rejection, or PTLD. Thirty-four transplants grafted into 32 recipients between 1995 and 2005 were followed for a median of 3.5 yr (range 1-9.8). All patients survived. Graft rejection occurred in 10 cases during the first year post-transplantation and graft...

    OPERA is one of the two detectors foreseen in the CERN Neutrino to Gran Sasso project, devoted to the detection of nu//mu into nu //tau oscillations in the parameter region suggested by SuperKamiokande data on atmospheric neutrinos. Bakelite RPCs will be used to instrument the iron yoke of the muon spectrometers. We present the results of long-term (greater than 6 months) streamer operations of real size OPERA RPCs at cosmic rays fluxes. Given the very low rate observed in the underground Gran Sasso Laboratories, under 3 km w.e., even this short time period is equivalent to more than 10 OPERA years. Results of tests with different gas mixtures are reported, in view of decreasing the streamer charge of operation for the RPCs employed in the experiment.

    Integrated learning is the need of the hour. We at Shifa College of Medicine switched to an integrated modular curriculum last year. In the present article, we describe our experience with the renal module in year 2 of a 5-yr undergraduate medical curriculum. A multidisciplinary renal modular team developed the relevant objectives, themes, and clinical cases. The learning strategies used were large-group interactive sessions, small-group learning, problem-based learning, practicals, and self-directed learning. Assessment was both formative and summative. Student and faculty feedback questionnaires were administered at the end of the module. Forty-four percent of the students agreed that the basic science and clinical concepts were well balanced and integrated. Fifty-seven percent of the students believed that important learning issues could be identified and that participation and critical thinking were encouraged during the small-group sessions. Eighty-five percent of the facilitators agreed that they were able to motivate students for critical thinking and better learning through integrating various disciplines. In conclusion, the integrated method of curricular delivery was well received by students and faculty members, and it can be used successfully in undergraduate medical education in developing countries.

  3. Integrating care for people with mental illness: the Care Programme Approach in England and its implications for long-term conditions management

    Full Text Available Introduction: This policy paper considers what the long-term conditions policies in England and other countries could learn from the experience of the Care Programme Approach (CPA. The CPA was introduced in England in April 1991 as the statutory framework for people requiring support in the community for more severe and enduring mental health problems. The CPA approach is an example of a long-standing 'care co-ordination' model that seeks to develop individualised care plans and then attempt to integrate care for patients from a range of providers. Policy description: The CPA experience is highly relevant to both the English and international debates on the future of long-term conditions management where the agenda has focused on developing co-ordinated care planning and delivery between health and social care; to prioritise upstream interventions that promote health and wellbeing; and to provide for a more personalised service. Conclusion: This review of the CPA experience suggests that there is the potential for better care integration for those patients with multiple or complex needs where a strategy of personalised care planning and pro-active care co-ordination is provided. However, such models will not reach their full potential unless a number of preconditions are met including: clear eligibility criteria; standardised measures of service quality; a mix of governance and incentives to hold providers accountable for such quality; and genuine patient involvement in their own care plans. Implications: Investment and professional support to the role of the care co-ordinator is particularly crucial. Care co-ordinators require the requisite skills and competencies to act as a  care professional  to the patient as well as to have the power to exert authority among other care professionals to ensure multidisciplinary care plans are implemented successfully.

    Full Text Available The stability of soil organic matter (SOM is a major source of uncertainty in predicting atmospheric CO2 concentration during the 21st century. Isolating the stable soil carbon (C from other, more labile, C fractions in soil is of prime importance for calibrating soil C simulation models, and gaining insights into the mechanisms that lead to soil C stability. Long-term experiments with continuous bare fallow (vegetation-free treatments in which the decay of soil C is monitored for decades after all inputs of C have stopped, provide a unique opportunity to assess the quantity of stable soil C. We analyzed data from six bare fallow experiments of long-duration (>30 yrs, covering a range of soil types and climate conditions, and sited at Askov (Denmark, Grignon and Versailles (France, Kursk (Russia, Rothamsted (UK, and Ultuna (Sweden. A conceptual three pool model dividing soil C into a labile pool (turnover time of a several years, an intermediate pool (turnover time of a several decades and a stable pool (turnover time of a several centuries or more fits well with the long term C decline observed in the bare fallow soils. The estimate of stable C ranged from 2.7 g C kg−1 at Rothamsted to 6.8 g C kg−1 at Grignon. The uncertainty associated with estimates of the stable pool was large due to the short duration of the fallow treatments relative to the turnover time of stable soil C. At Versailles, where there is least uncertainty associated with the determination of a stable pool, the soil contains predominantly stable C after 80 years of continuous bare fallow. Such a site represents a unique research platform for characterization of the nature of stable SOM and its vulnerability to global change.

    The central tenet of biodiversity-ecosystem function (BEF) theory, that species richness increases function, could motivate restoration practitioners to incorporate a greater number of species into their projects. But it is not yet clear how well BEF theory predicts outcomes of restoration, because it has been developed through tests involving short-run and tightly controlled (e.g., weeded) experiments. Thus, we resampled our 1997 BEF experiment in a restored salt marsh to test for long-term effects of species richness (plantings with 1, 3, and 6 species per 2 x 2 m plot), with multiple ecosystem functions as response variables. Over 11 years, 1- and 6-species assemblages converged on intermediate richness (mean = 3.9 species/ 0.25-m2 plot), and composition changed nonrandomly throughout the site. While three species became rare, the two most productive species became co-dominant. The two dominants controlled and increased shoot biomass, which appeared to decrease species richness. Diversity-function relationships became less positive over 11 years and differed significantly with (a) the species-richness metric (planted vs. measured), and (b) the indicator of function (shoot biomass, height, and canopy layering). The loss of positive relationships between species richness and function in our restored site began soon after we stopped weeding and continued with increasing dominance by productive species. Where species-rich plantings are unlikely to ensure long-term restoration of functions, as in our salt marsh, we recommend dual efforts to establish (1) dominant species that provide high levels of target functions, and (2) subordinate species, which might provide additional functions under current or future conditions.

    Takotsubo cardiomyopathy is a reversible condition mimicking acute myocardial infarction. The phenomenon is associated with emotional and physical stressful trigger events. Evidence-based patient counselling should be based on disease-specific knowledge of patient experiences. The aim of the study was to describe women's experiences of Takotsubo cardiomyopathy in a short-term perspective. The study design was explorative and descriptive. Semi-structured interviews were conducted with 14 women diagnosed with Takotsubo cardiomyopathy, 1 day to 9 months after hospitalisation. The transcriptions underwent qualitative content analysis. The main theme that emerged was Takotsubo cardiomyopathy as a continuous process of making sense and adapting. To begin with, understanding and coping with signs and symptoms were described as having a diversity of signs and symptoms, taking actions towards signs and symptoms, receiving treatment for suspected ST/non ST-elevation myocardial infarction diagnosis and finally being diagnosed with Takotsubo cardiomyopathy. Understanding the context of illness was expressed as getting treated for Takotsubo cardiomyopathy diagnosis and having previous stressful conditions of life. The changing perspective that emanated was a combination of having prospects and expectations and experiencing limitations. Finally, managing to live with Takotsubo cardiomyopathy was manifested as returning home with the illness and receiving follow-up health care. Information on regaining prior health status and capacity within a short-term perspective may not be accurate. These women struggle and require education and counselling from healthcare professionals to comprehend and manage having a Takotsubo cardiomyopathy diagnosis. Women experiencing Takotsubo cardiomyopathy may be a target group for holistic and individual health care with a longer duration of follow-up. © 2014 Nordic College of Caring Science.

    The concept of empowerment, widely accepted and utilized in many health-related disciplines, connotes a process of gaining control over one's life and influencing the organizational and social structures in which one lives. This article demonstrates an example of how empowering education can be applied on foreign nursing aides working in long-term care facilities and how differing empowering strategies, processes and effects can be adopted to address differing situations and ethnic backgrounds. How high priority issues of concern for foreign nurses are handled impacts upon their ability to perform their jobs well. Empowering strategies can help deal with such issues more effectively and, as a result, reduce work stress and improve on-the-job performance. During the preparation stage, the empowerment process focuses on building a trusting partner relationship. During the work stage, the process focuses on inspiring foreign nurses' self-awareness, encouraging their perceiving the barriers and needs at work, and, most importantly, encouraging nurses to think critically and positively and to provide feedback. The effects of empowering education include enhanced problem solving abilities, rising nurse self-confidence in his/her caretaking abilities, enhanced self-esteem, and improved adaptation to the work environment. This paper provides empirical experiences with regard to the application of empowering education in clinical settings as well as process and management strategies related to foreign nursing aides employed in long-term care facilities.

    Long-term care (LTC) residents with cognitive impairments frequently experience limited mobility and participation in preferred activities. Although a power wheelchair could mitigate some of these mobility and participation challenges, this technology is often not prescribed for this population due to safety concerns. An intelligent power wheelchair (IPW) system represents a potential intervention that could help to overcome these concerns. The purpose of this study was to explore a) how residents experienced an IPW that used three different modes of control and b) what perceived effect the IPW would have on their daily lives. We interviewed 10 LTC residents with mild or moderate cognitive impairment twice, once before and once after testing the IPW. Interviews were conducted using a semi-structured interview guide, audio recorded and transcribed verbatim for thematic analyses. Our analyses identified three overarching themes: (1) the difference an IPW would make, (2) the potential impact of the IPW on others and (3) IPW-related concerns. Findings from this study confirm the need for and potential benefits of IPW use in LTC. Future studies will involve testing IPW improvements based on feedback and insights from this study. Implications for rehabilitation Intelligent power wheelchairs may enhance participation and improve safety and feelings of well-being for long-term care residents with cognitive impairments. Intelligent power wheelchairs could potentially have an equally positive impact on facility staff, other residents, and family and friends by decreasing workload and increasing safety.

    Full Text Available Food induced sensitization has been reported in pediatric liver recipients. However long term follow up has not been established so far. We report here our experience regarding 3 pediatric patients who developed acquired food allergy after liver transplantation. The first patient suffered from persistent diarrhea and eczema. The second one presented with abdominal pain with no signs of rejection, abdominal discomfort, vomiting when ingesting milk proteins and responded well to the elimination diet. The third patient presented with facial angioedema and hoarseness of voice. She had multiple food allergies and reacted to milk, egg and sesame. All the patients had elevated total Immunoglobulin E (IgE and elevated specific IgE antibodies to the implicated food allergens. The first patient presented clinical manifestations of allergy when she was 19 months old. The second patient became allergic at the age of 16 and the third patient at the age of 3. The symptoms of food allergy persisted for 8 years in the first case and for 2 years in the other two cases. Low levels of specific IgE antibodies to the implicated food allergens and an enhanced T-helper 1 cell immune response toward interferon-gamma production were markers of tolerance acquisition. The long term prognosis in our cases was excellent. Food allergy resolved in all the patients. The long term prognosis of acquired food allergy after liver transplantation is currently obscure. More studies would be needed including greater number of patients to determine whether acquired food allergy is transient in pediatric liver recipients.

  11. Long-Term Soil Experiments: A Key to Managing Earth's Rapidly Changing Critical Zones

    2014-12-01

    In a few decades, managers of Earth's Critical Zones (biota, humans, land, and water) will be challenged to double food and fiber production and diminish adverse effects of management on the wider environment. To meet these challenges, an array of scientific approaches is being used to increase understanding of Critical Zone functioning and evolution, and one amongst these approaches needs to be long-term soil field studies to move us beyond black boxing the belowground Critical Zone, i.e., to further understanding of processes driving changes in the soil environment. Long-term soil experiments (LTSEs) provide direct observations of soil change and functioning across time scales of decades, data critical for biological, biogeochemical, and environmental assessments of sustainability; for predictions of soil fertility, productivity, and soil-environment interactions; and for developing models at a wide range of temporal and spatial scales. Unfortunately, LTSEs globally are not in a good state, and they take years to mature, are vulnerable to loss, and even today remain to be fully inventoried. Of the 250 LTSEs in a web-based network, results demonstrate that soils and belowground Critical Zones are highly dynamic and responsive to human management. The objective of this study is to review the contemporary state of LTSEs and consider how they contribute to three open questions: (1) can soils sustain a doubling of food production in the coming decades without further impinging on the wider environment, (2) how do soils interact with the global C cycle, and (3) how can soil management establish greater control over nutrient cycling. While LTSEs produce significant data and perspectives for all three questions, there is on-going need and opportunity for reviews of the long-term soil-research base, for establishment of an efficiently run network of LTSEs aimed at sustainability and improving management control over C and nutrient cycling, and for research teams that

    An integrated controlling system and a unified database for high throughput protein crystallography experiments have been developed. Main features of protein crystallography experiments (purification, crystallization, crystal harvesting, data collection, data processing) were integrated into the software under development. All information necessary to perform protein crystallography experiments is stored (except raw X-ray data that are stored in a central data server) in a MySQL relational database. The database contains four mutually linked hierarchical trees describing protein crystals, data collection of protein crystal and experimental data processing. A database editor was designed and developed. The editor supports basic database functions to view, create, modify and delete user records in the database. Two search engines were realized: direct search of necessary information in the database and object oriented search. The system is based on TCP/IP secure UNIX sockets with four predefined sending and receiving behaviors, which support communications between all connected servers and clients with remote control functions (creating and modifying data for experimental conditions, data acquisition, viewing experimental data, and performing data processing). Two secure login schemes were designed and developed: a direct method (using the developed Linux clients with secure connection) and an indirect method (using the secure SSL connection using secure X11 support from any operating system with X-terminal and SSH support). A part of the system has been implemented on a new MAD beam line, NW12, at the Photon Factory Advanced Ring for general user experiments.

    2012-01-01

    This study explored and analysed how patients experienced possibilities for, and barriers to, work return after participation in a multi-professional pain-rehabilitation program followed by a coached work-training program (CWT). Eleven informants (8 women/3 men) with long-term musculoskeletal pain who had participated in the CWT program for 4-21 months (mean=11) comprised the study. A qualitative emergent design was used. Data collected with interviews were analysed using the constant comparison method of grounded theory. Triangulation in researchers were used. The analyses of the interviews resulted in the development of a three-category theoretical model, which was named "a way back to work". The main category "Experience of a way back to work" consisted of the informants' experience during the process between unemployment and employment. The category "Support" describes the help the informants received from various actors, and the category "Negative response" describes negative responses from the actors involved, which was an important barrier in the process between unemployment and employment. Professional individualised support, participants feeling involved in their rehabilitation process, coaching at real workplaces and multi-professional team including health care personnel, were valuable during the process towards work.

    2007-04-01

    The purpose of this study was to explore the elderly's experience and perceptions of group music therapy. The residents of a long term care institution received group music therapy for one year. Afterwards, three interviews were conducted in focus groups of between six and eight of the elderly. Their ages ranged from 64 to 90. Ninety-five percent of these elderly subjects participated in the therapy for over ten months. The tape-recorded interviews were transcribed and analyzed using content analysis. Six themes emerged regarding the elderly subjects' experiences and perceptions of group music therapy, as follows: (1) becoming more willing to participate; (2) feeling pain relief and more controlled moods; (3) getting physically better; (4) being more motivated to live; (5) learning positive personal interaction and obedience to the rules of the group; and (6) learning skills to improve personal health. This information might be used as a helpful and valuable reference in nursing education and by administrative organizations involved in the planning of therapeutic programs for the elderly.

    Very short study abroad programs may be most feasible in undergraduate nursing programs, but little research describes their value for prospective nurses. The narratives of senior baccalaureate nursing students (N = 62) who traveled for 2 weeks to Cape Coast, Ghana, between semesters for a faculty-led community health clinical experience were analyzed. Students responded to pre- and posttravel semi-structured, open-ended prompts regarding expectations and perceptions of culture, health, and happiness. Data were analyzed using a qualitative descriptive approach. Four themes emerged related to perceptions of culture, relationships with community, definitions of health and happiness, and adaptability and innovation. African American students' (n = 3) responses highlighted unique themes regarding personal identity. Student perceptions of culture demonstrated progression through previously described stages of cultural competence. Relatively novel themes regarding community relationships, perceptions of health and happiness, and adaptability suggest additional value of this short-term study abroad experience for nursing students.

    Long-term field experiments performed in experimental farms are important research tools to assess the soil physical quality (SPQ) given that relatively stable conditions can be expected in these soils. However, different SPQ indicators may sometimes provide redundant or conflicting results, making difficult an SPQ evaluation (Castellini et al., 2014). As a consequence, it is necessary to apply appropriate statistical procedures to obtain a minimum set of key indicators. The study was carried out at the Experimental Farm of CREA-SCA (Foggia) in two long-term field experiments performed on durum wheat. The first long-term experiment is aiming at evaluating the effects of two residue management systems (burning, B or soil incorporation of crop residues, I) while the second at comparing the effect of tillage (conventional tillage, CT) and sod-seeding (direct drilling, DD). In order to take into account both optimal and non-optimal soil conditions, five SPQ indicators were monitored at 5-6 sampling dates during the crop season (i.e., between November and June): soil bulk density (BD), macroporosity (PMAC), air capacity (AC), plant available water capacity (PAWC) and relative field capacity (RFC). Two additional data sets, collected on DD plot in different cropping seasons and in Sicilian soils differing for texture, depth and land use (N=140), were also used with the aim to check the correlation among indicators. Impact of soil management was assessed by comparing SPQ evaluated under different management systems with optimal reference values reported in literature. Two techniques of multivariate analysis (principal component analysis, PCA and stepwise discriminant analysis, SDA) were applied to select the most suitable indicator to facilitate the judgment on SPQ. Regardless of the considered management system, sampling date or auxiliary data set, correlation matrices always showed significant negative relationships between RFC and AC. Decreasing RFC at increasing AC is

    This research explored the experiences of service users and providers during the implementation of the National Service Framework (NSF) for Long-Term (Neurological) Conditions (LTNCs). A participatory qualitative research design was employed. Data were collected using 50 semi-structured interviews with service users, 25 of whom were re-interviewed on three occasions. Forty-five semi-structured interviews were also conducted with service providers who worked with individuals with LTNCs. Interviews focused on health, well-being and quality of life in relation to service provision, access and delivery. Data were thematically analysed individually and collaboratively during two data analysis workshops. Three major themes were identified that related to the implementation of the NSF: "Diagnosis and treatment", "Better connected services" and "On-going rehabilitation". Service users reported that effective care was provided when in hospital settings but such treatments often terminated on return to their communities despite on-going need. In hospital and community settings, service providers indicated that they lacked the support and resources to provide continuous care, with patients reaching a crisis point before referral to specialist care. This research highlighted a range of issues concerning the recent UK-drive towards patient-centred approaches within healthcare, as service users were disempowered within the LTNC care pathway. Moreover, service providers indicated that resource constraints limited their ability to provide long-term, intensive and integrated service provision. Our research suggests that many service users with long-term neurological conditions experienced disconnections between services within their National Service Framework care pathway. For health and social care practitioners, a lack of continuity within a care pathway was suggested to be most pertinent following immediate care and moving to rehabilitative care. Our findings also indicate that

    Full Text Available This article discusses the convenience of adopting an approach of Collective Spatial Analysis in the P/PGIS processes, with the aim of improving the collection and integration of knowledge and local expertise in decision-making, mainly in the fields of planning and adopting territorial policies. Based on empirical evidence, as a result of the review of scientific articles from the Web of Science database, in which it is displayed how the knowledge and experience of people involved in decision-making supported by P/PGIS are collected and used, a prototype of a WEB-GSDSS application has been developed. This prototype allows a group of people to participate anonymously, in an asynchronous and distributed way, in a decision-making process to locate goods, services, or events through the convergence of their views. Via this application, two case studies for planning services in districts of Ecuador and Italy were carried out. Early results suggest that in P/PGIS local and external actors contribute their knowledge and experience to generate information that afterwards is integrated and analysed in the decision-making process. On the other hand, in a Collective Spatial Analysis, these actors analyse and generate information in conjunction with their knowledge and experience during the process of decision-making. We conclude that, although the Collective Spatial Analysis approach presented is in a subjective and initial stage, it does drive improvements in the collection and integration of knowledge and local experience, foremost among them is an interdisciplinary geo-consensus.

    hydrolysis at the temperatures tested here. It may be hypothesised that the alkaline hydrolysis has even not been observed in the experiments. However, if this is true, cellulose degradation proceeded via another unknown type of reaction. Mass balances for carbon show that the large majority of reaction products found in solution can be explained by formation of isosaccharinic acids and other low-molecular weight carboxylic acids. With respect to long-term predictions for cellulose degradation at room temperature it can be concluded that the kinetic parameters for alkaline hydrolysis as proposed in the work of PAVASARS (Linkoping Studies in Arts and Science, 196, Linkoping University, Sweden, 1999) are too large and that complete cellulose degradation at these temperatures occurs only within time scales larger than hundreds of years. However, it is not possible from the experimental evidences, to corroborate the validity of a linear extrapolation (Arrhenius equation) of the reaction rates measured at temperatures between 140 and 190{sup o}C to room temperature, from which it was previously concluded that complete cellulose degradation would take time spans of the order of millions of years. An interesting observation in the present experiments is the chemical instability of aisosaccharinic acid at 90{sup o}C, which has been hypothetically interpreted as a fragmentation induced by the sorption of {alpha}-isosaccharinic acid on Ca(OH){sub 2}. Carbon mass balances show that {alpha}-isosaccharinic acid is thereby transformed to other lowmolecular weight carboxylic acids. Such a reaction would be an interesting long-term perspective for performance assessment of the disposal of cellulose-containing radioactive waste, in that it may reduce the concentration of organic compounds strongly complexing radionuclides.

    2003-01-01

    High Energy Physics research (HEP) involves the design of readout electron- ics for its experiments, which generate a high radiation ¯eld in the detectors. The several integrated circuits placed in the future Large Hadron Collider (LHC) experiments' environment have to resist the radiation and carry out their normal operation. In this thesis I will describe in detail what, during my 10-months partic- ipation in the digital section of the Microelectronics group at CERN, I had the possibility to work on: - The design of a radiation-tolerant data readout digital integrated cir- cuit in a 0.25 ¹m CMOS technology, called \\the Kchip", for the CMS preshower front-end system. This will be described in Chapter 3. - The design of a radiation-tolerant SRAM integrated circuit in a 0.13 ¹m CMOS technology, for technology radiation testing purposes and fu- ture applications in the HEP ¯eld. The SRAM will be described in Chapter 4. All the work has carried out under the supervision and with the help of Dr. Kostas Klouki...

    An integrated liquid oxygen (LOx) and methane propulsion system where common propellants are fed to the reaction control system and main engines offers advantages in performance, simplicity, reliability, and reusability. LOx/Methane provides new capabilities to use propellants that are manufactured on the Mars surface for ascent return and to integrate with power and life support systems. The clean burning, non-toxic, high vapor pressure propellants provide significant advantages for reliable ignition in a space vacuum, and for reliable safing or purging of a space-based vehicle. The NASA Advanced Exploration Systems (AES) Morpheus lander demonstrated many of these key attributes as it completed over 65 tests including 15 flights through 2014. Morpheus is a prototype of LOx/Methane propellant lander vehicle with a fully integrated propulsion system. The Morpheus lander flight demonstrations led to the proposal to use LOx/Methane for a Discovery class mission, named Moon Aging Regolith Experiment (MARE) to land an in-situ science payload for Southwest Research Institute on the Lunar surface. Lox/Methane is extensible to human spacecraft for many transportation elements of a Mars architecture. This paper discusses LOx/Methane propulsion systems in regards to trade studies, the Morpheus project experience, the MARE NAVIS (NASA Autonomous Vehicle for In-situ Science) lander, and future possible applications. The paper also discusses technology research and development needs for Lox/Methane propulsion systems.

Such an experiment has provided critical data about the timing, the amplitude and the spatial distribution of deformation. In complement, water chemistry provides some insights about the time scales involved in kinetic reactions. In particular, the long term monitoring of water chemistry allows to identify denitrification processes in some pyrite bearing fractures. The various type of experiments and monitoring conducted at different scales at the Ploemeur site allow to provide a large amount of data of various types that can be used to test flow and transport models.

  8. Monitoring the Long-Term Effectiveness of Integrated Safety Management System (ISMS) Implementation Through Use of a Performance Dashboard Process

    2016-12-01

    Full Text Available Integral and deep pedagogical content knowledge can support future primary teachers’ ability to follow ideas of education for sustainability in science class. Initial teacher education provides opportunity to learn what and how to teach but still the practical experiences of teaching can reveal uneven development of student teachers’ professionality. The aim of the study is to describe how future primary teachers reflect on their experiences about science teaching and what components of science pedagogical content knowledge they see as meaningful. A questionnaire and interviews were used. The results reveal the deep impact of teaching practice on students’ understanding of the role of a teacher in supporting pupils’ acquisition of scientific skills. The experiences described are related more to teaching and learning in general and less with science-specific factors. Nevertheless, students described changes in mission e.g. how they learned about their role through pupils’ achievements and thinking about science. Changes in professional identity were mentioned rarely but this could point to an underestimated resource issue for teacher education. Positive changes in professional identity may help students to decide to choose more integral strategies in science teaching and thus promote more sustainability oriented teaching.

    Many people confronting mental health problems are excluded from participation in paid work. Supervisor engagement is essential for successful job placement. To elicit supervisor perspectives on the challenges involved in fostering integration to support individuals with mental health problems (trainees) in their job placement at ordinary companies. Explorative, qualitative designed study with a phenomenological approach, based on semi-structured interviews with 15 supervisors involved in job placements for a total of 105 trainees (mean 7, min-max. 1-30, SD 8). Data were analysed using qualitative content analysis. Superviors experience two interrelated dilemmas concerning knowledge of the trainee and degree of preferential treatment. Challenges to obtaining successful integration were; motivational: 1) Supervisors previous experience with trainees encourages future engagement, 2) Developing a realistic picture of the situation, and 3) Disclosure and knowledge of mental health problems, and continuity challenges: 4) Sustaining trainee cooperation throughout the placement process, 5) Building and maintaining a good relationship between supervisor and trainee, and 6) Ensuring continuous cooperation with the social security system and other stakeholders. Supervisors experience relational dilemmas regarding pre-judgment, privacy and equality. Job placement seem to be maximized when the stakeholders are motivated and recognize that cooperation must be a continuous process.

    In May 2014, a short-term study-abroad experience was conducted in Finland through a course offered at Indiana State University (ISU). Students and faculty from ISU and Eastern Illinois University participated in the experience, which was created to facilitate a cross-cultural comparison of long-term-care settings in the United States and Finland. With its outstanding system of caring for the health and social needs of its aging populace, Finland is a logical model to examine when considering ways to improve the quality of life for older adults who require care in the United States . Those participating in the course visited a series of long-term-care facilities in the region surrounding Terre Haute, Indiana, then travelled to Lappeenranta, Finland to visit parallel sites. Through limited-participation observation and semistructured interviews, similarities and differences in experiences, educations, and policies affecting long-term care workers in the United States and Finland were identified and are described here.

    Managing production environments in ways that promote weed community diversity may enhance both crop production and the development of a more sustainable agriculture. This study analyzed data of productivity of maize (corn) and soybean in plots in the Main Cropping System Experiment (MCSE) at the W. K. Kellogg Biological Station Long-Term Ecological Research (KBS-LTER) in Michigan, USA, from 1996 to 2011. We used models derived from population ecology to explore how weed diversity, temperature, and precipitation interact with crop yields. Using three types of models that considered internal and external (climate and weeds) factors, with additive or non-linear variants, we found that changes in weed diversity were associated with changes in rates of crop yield increase over time for both maize and soybeans. The intrinsic capacity for soybean yield increase in response to the environment was greater under more diverse weed communities. Soybean production risks were greatest in the least weed diverse systems, in which each weed species lost was associated with progressively greater crop yield losses. Managing for weed community diversity, while suppressing dominant, highly competitive weeds, may be a helpful strategy for supporting long term increases in soybean productivity. In maize, there was a negative and non-additive response of yields to the interaction between weed diversity and minimum air temperatures. When cold temperatures constrained potential maize productivity through limited resources, negative interactions with weed diversity became more pronounced. We suggest that: (1) maize was less competitive in cold years allowing higher weed diversity and the dominance of some weed species; or (2) that cold years resulted in increased weed richness and prevalence of competitive weeds, thus reducing crop yields. Therefore, we propose to control dominant weed species especially in the years of low yield and extreme minimum temperatures to improve maize yields

    2017-12-01

    The purpose of this retrospective study was to examine the experiences of adults with visual impairments during school-based integrated physical education (PE). An interpretative phenomenological analysis (IPA) research approach was used and 16 adults (ages 21-48 years; 10 women, 6 men) with visual impairments acted as participants for this study. The primary sources of data were semistructured audiotaped telephone interviews and reflective field notes, which were recorded during and immediately following each interview. Thematic development was undertaken utilizing a 3-step analytical process guided by IPA. Based on the data analysis, 3 interrelated themes emerged from the participant transcripts: (a) feelings about "being put to the side," frustration and inadequacy; (b) "She is blind, she can't do it," debilitating feelings from physical educators' attitudes; and (c) "not self-esteem raising," feelings about peer interactions. The 1st theme described the participants' experiences and ascribed meaning to exclusionary practices. The 2nd theme described the participants' frustration over being treated differently by their PE teachers because of their visual impairments. Lastly, "not self-esteem raising," feelings about peer interactions demonstrated how participants felt about issues regarding challenging social situations with peers in PE. Utilizing an IPA approach, the researchers uncovered 3 interrelated themes that depicted central feelings, experiences, and reflections, which informed the meaning of the participants' PE experiences. The emerged themes provide unique insight into the embodied experiences of those with visual impairments in PE and fill a previous gap in the extant literature.

    Preterm infants' mothers face several challenges when providing critical breast milk for their infants; therefore, sensitive and evidence-based counseling and support are needed. However, a general view of the experiences preterm infants' mothers can face during their infants' hospitalization and after discharge is lacking. The aim of this integrative review was to explore practical and emotional experiences of preterm infants' mothers with respect to breast milk expression and breastfeeding, from the birth of the preterm infant, during the neonatal intensive care unit (NICU) stay, and postdischarge until the cessation of breastfeeding. A systematic literature search from MEDLINE, CINAHL, PsycInfo, and Cochrane databases were performed. The search resulted in 20 qualitative and 3 quantitative studies. The data were analyzed by thematic analysis. Coping was the central theme in mothers' experiences. The benefits of breast milk served both as a supportive factor and an obstructive factor for the mothers, and breastfeeding was used to rebuild connection and motherhood. Simultaneously, the mothers needed to cope with new demands, interfering NICU environment, demanding expressing, and difficulties with breastfeeding. Expressing and breastfeeding are important for the mothers to contribute to their infants' care and to rebuild the interrupted connection. Evidence-based and sensitive informational and practical counseling are vital for the mothers. Intensive emotional support is important during encountered problems and during cessation. Future research is needed about mothers' experiences using supplementation methods, test-weighing, exploring experiences of mothers of late-preterm infants, and the validity of the concept of coping with this phenomenon.

  16. Long-term geoelectrical monitoring of laboratory freeze-thaw experiments on bedrock samples

    Much attention has recently focussed on the continuous and near-real-time geophysical monitoring of permafrost-affected bedrock with permanently installed sensor arrays. It is hoped that such efforts will enhance process understanding in such environments (permafrost degradation, weathering mechanisms) and augment our capability to predict future instabilities of rock walls and slopes. With regard to electrical methods for example, recent work has demonstrated that temperature-calibrated electrical resistivity tomography (ERT) is capable of imaging recession and re-advance of rock permafrost in response to the ambient temperature regime. However, field experience also shows that several fundamental improvements to ERT methodology are still required to achieve the desired sensitivity, spatial-temporal resolution and long-term robustness that must underpin continuous geophysical measurements. We have applied 4D geoelectrical tomography to monitoring laboratory experiments simulating permafrost growth, persistence and thaw in bedrock over a period of 26 months. Six water-saturated samples of limestone and chalk of varying porosity represented lithologies commonly affected by permafrost-related instability. Time-lapse imaging of the samples was undertaken during multiple successive freeze-thaw cycles, emulating annual seasonal change over several decades. Further experimental control was provided by simultaneous measurements of vertical profiles of temperature and moisture content within the bedrock samples. These experiments have helped develop an alternative methodology for the volumetric imaging of permafrost bedrock and tracking active layer dynamics. Capacitive resistivity imaging (CRI), a technique based upon low-frequency, capacitively-coupled measurements emulates ERT methodology, but without the need for galvanic contact on frozen rock. The latter is perceived as a key potential weakness, which could lead to significant limitations as a result of the variable

    2012-02-01

    Full Text Available Prescribed burning is used in many geographical areas for multiple and integrated objectives (wildfire prevention, habitat conservation, grazing management. In Europe the collaboration between researchers and fire professionals has brought to implement this technique over increasing areas (~104 ha year-1, effectively and efficiently. In Italy prescribed burning has not been much studied and it is rarely applied. A new interest is recently rising. Some Regions particularly threatened by wildfires have updated their legislation and set up procedures to authorize prescribed fire experiments and interventions. From 2004 to 2011 several scientific, operative and training experiences have been carried out at a regional level (Basilicata, Campania, Friuli Venezia Giulia, Piemonte, Sardegna, Toscana. The present paper aims to: (i document and compare these regional programs; (ii discuss their frameworks and limitations; (iii provide information about objectives, prescriptions, methods and results. The study has involved Universities, Forest Corps, Civil Protection, Municipalities, Parks and professionals from Italy and other Countries. Interventions have regarded integrated objectives (fire hazard reduction; habitat conservation; forest and grazing management, and involved several vegetation types (broadleaved and conifer forests; Mediterranean and Continental shrublands; grasslands. Studies on fire behaviour and ecology have helped to set prescriptions for specific objectives and environments. Results have been transferred to professionals through training sessions. Several common elements are outlined: integrated objectives, multidisciplinary character, training and research products. Ecological questions, certification to the use of fire, communication to local communities and the proposal of new studies, are some of the issues outlined in the discussion. The present study is the first review at national level and we hope it will help to deepen the

    Chromosome translocations are an established biomarker of cumulative exposure to external ionising radiation. Airline pilots are exposed to cosmic ionising radiation, but few flight crew studies have examined translocations in relation to flight experience. We determined the frequency of translocations in the peripheral blood lymphocytes of 83 airline pilots and 50 comparison subjects (mean age 47 and 46 years, respectively). Translocations were scored in an average of 1039 cell equivalents (CE) per subject using fluorescence in situ hybridisation (FISH) whole chromosome painting and expressed per 100 CE. Negative binomial regression models were used to assess the relationship between translocation frequency and exposure status and flight years, adjusting for age, diagnostic x ray procedures, and military flying. There was no significant difference in the adjusted mean translocation frequency of pilots and comparison subjects (0.37 (SE 0.04) vs 0.38 (SE 0.06) translocations/100 CE, respectively). However, among pilots, the adjusted translocation frequency was significantly associated with flight years (p = 0.01) with rate ratios of 1.06 (95% CI 1.01 to 1.11) and 1.81 (95% CI 1.16 to 2.82) for a 1- and 10-year incremental increase in flight years, respectively. The adjusted rate ratio for pilots in the highest compared to the lowest quartile of flight years was 2.59 (95% CI 1.26 to 5.33). Our data suggests that pilots with long-term flying experience may be exposed to biologically significant doses of ionising radiation. Epidemiological studies with longer follow-up of larger cohorts of pilots with a wide range of radiation exposure levels are needed to clarify the relationship between cosmic radiation exposure and cancer risk.

  1. Fission Product Transport and Source Terms in HTRs: Experience from AVR Pebble Bed Reactor

    Directory of Open Access Journals (Sweden)

    Rainer Moormann

    2008-01-01

    Full Text Available Fission products deposited in the coolant circuit outside of the active core play a dominant role in source term estimations for advanced small pebble bed HTRs, particularly in design basis accidents (DBA. The deposited fission products may be released in depressurization accidents because present pebble bed HTR concepts abstain from a gas tight containment. Contamination of the circuit also hinders maintenance work. Experiments, performed from 1972 to 88 on the AVR, an experimental pebble bed HTR, allow for a deeper insight into fission product transport behavior. The activity deposition per coolant pass was lower than expected and was influenced by fission product chemistry and by presence of carbonaceous dust. The latter lead also to inconsistencies between Cs plate out experiments in laboratory and in AVR. The deposition behavior of Ag was in line with present models. Dust as activity carrier is of safety relevance because of its mobility and of its sorption capability for fission products. All metal surfaces in pebble bed reactors were covered by a carbonaceous dust layer. Dust in AVR was produced by abrasion in amounts of about 5 kg/y. Additional dust sources in AVR were ours oil ingress and peeling of fuel element surfaces due to an air ingress. Dust has a size of about 1  m, consists mainly of graphite, is partly remobilized by flow perturbations, and deposits with time constants of 1 to 2 hours. In future reactors, an efficient filtering via a gas tight containment is required because accidents with fast depressurizations induce dust mobilization. Enhanced core temperatures in normal operation as in AVR and broken fuel pebbles have to be considered, as inflammable dust concentrations in the gas phase.

    Four pairs of fresh and partly-weathered granitoids, obtained from well-characterized watersheds—Merced River, CA, USA; Panola, GA, USA; Loch Vale, CO, USA, and Rio Icacos, Puerto Rico—were reacted in columns under ambient laboratory conditions for 13.8 yrs, the longest running experimental weathering study to date. Low total column mass losses (flow rates. Effluent Na concentrations showed no clear trend with time during the last decade of reaction (fresh granitoids) or increased slowly with time (weathered granitoids). Analysis of cumulative Na release indicated that plagioclase dissolution achieved steady state in 3 of the 4 fresh granitoids during the last decade of reaction. Surface-area normalized plagioclase dissolution rates exhibited a narrow range (0.95 to 1.26 10-13 moles m-2 s-1), in spite of significant stoichiometric differences (An0.21 to An0.50). Rates were an order of magnitude slower than previously reported in shorter duration experiments but generally 2 to 3 orders of magnitude faster than corresponding natural analogs. CrunchFlow simulations indicated that more than a hundredfold decrease in column flow rates would be required to produce near-saturation reaction affinities that would start to slow plagioclase weathering to real-world levels. Extending simulations to approximate long term weathering in naturally weathered profiles required additional decreases in the intrinsic plagioclase dissolution and kaolinite precipitation rates and relatively large decreases in the fluid flow rate, implying that exposure to reactive mineral surfaces is significantly limited in the natural environment compared to column experiments.

    2016-11-15

    Highlights: • The paper describes the experience gained in the integration of different systems for the control and data acquisition system of the ITER Neutral Beam Test Facility. • It describes the way the different frameworks have been integrated. • It reports some lessons learnt during system integration. • It reports some authors’ considerations about the development the ITER CODAC. - Abstract: The ITER Neutral Beam (NBI) Test Facility, under construction in Padova, Italy consists in the ITER full scale ion source for the heating neutral beam injector, referred to as SPIDER, and the full size prototype injector, referred to as MITICA. The Control and Data Acquisition System (CODAS) for SPIDER has been developed and is going to be in operation in 2016. The system is composed of four main components: Supervision, Slow Control, Fast Control and Data Acquisition. These components interact with each other to carry out the system operation and, since they represent a common pattern in fusion experiments, software frameworks have been used for each (set of) component. In order to reuse as far as possible the architecture developed for SPIDER, it is important to clearly define the boundaries and the interfaces among the system components so that the implementation of any component can be replaced without affecting the overall architecture. This work reports the experience gained in the development of SPIDER components, highlighting the importance in the definition of generic interfaces among component, showing how the specific solutions have been adapted to such interfaces and suggesting possible approaches for the development of other ITER subsystems.

  4. Experiment/facility requirements document for the Space Station Furnace Facility. Section 1: Integrated configuration

    Science.gov (United States)

    1992-01-01

    The function of the Space Station Furnace Facility (SSFF) is to support materials research into the crystal growth and solidification processes of electronic and photonic materials, metals and alloys, and glasses and ceramics. To support this broad base of research requirements, the SSFF will employ a variety of furnace modules which will be operated, regulated, and supported by a core of common subsystems. Furnace modules may be reconfigured or specifically developed to provide unique solidification conditions for each set of experiments. The SSFF modular approach permits the addition of new or scaled-up furnace modules to support the evolution of the facility as new science requirements are identified. The SSFF Core is of modular design to permit augmentation for enhanced capabilities. The fully integrated configuration of the SSFF will consist of three racks with the capability of supporting up to two furnace modules per rack. The initial configuration of the SSFF will consist of two of the three racks and one furnace module. This Experiment/Facility Requirements Document (E/FRD) describes the integrated facility requirements for the Space Station Freedom (SSF) Integrated Configuration-1 (IC1) mission. The IC1 SSFF will consist of two racks: the Core Rack, with the centralized subsystem equipment; and the Experiment Rack-1, with Furnace Module-1 and the distributed subsystem equipment to support the furnace. The SSFF support functions are provided by the following Core subsystems: power conditioning and distribution subsystem (SSFF PCDS); data management subsystem (SSFF DMS); thermal control Subsystem (SSFF TCS); gas distribution subsystem (SSFF GDS); and mechanical structures subsystem (SSFF MSS).

    Highlights: • For checking property of the hybrid blanket by integral experiments, three mockups are established. • In spherical mockup with depleted uranium and cubic mockup with natural uranium, the plutonium production rates and uranium fission rates are measured. • In spherical mockup with depleted uranium and LiPb, tritium production rates are measured. • The measured results are compared to the calculated ones with MCNP-4B code and ENDF/B-VI library data. - Abstract: The paper describes recent progress in integral neutronics experiments in the analytical mockups for the blanket in a fusion-fission hybrid energy reactor. A conceptual blanket of the hybrid reactor is mainly loaded with natural uranium and lithium material. In the fission fuel region, uranium material and light water are arranged alternately. The mockups of the conceptual blanket are designed and used for checking neutron property of the blanket by integral experiments. Based on materials available, the spherical fission mockup for fission research and plutonium production consists of three layers of depleted uranium shells and several layers of polyethylene and graphite shells. The spherical lithium mockup for tritium production consists of depleted uranium and LiPb alloy shells. The cubic mockup consists of natural uranium and polyethylene and its structure is basically consistent with one of the fuel region. In the mockups with the D-T neutron source, the plutonium production rates, uranium fission rates and tritium production rates are measured, separately. The measured results are compared to the calculated ones with MCNP-4B code and ENDF/B-VI library data.

    Background: Recent combat operations have involved large numbers of personnel. Long-term health effects of military deployment remain largely unknown. Objectives: To examine patterns and trends in long-term disability among combat veterans and to relate disability to aspects of wartime experience. Participants: A total of 60,228 Australian military personnel deployed between 1962 and 1975 during the Vietnam War, and 82,877 military personnel who were not deployed overseas. Outcome Measures: Accepted physician-assessed disability claims were evaluated over follow-up periods up to 50 years after deployment, and compared with age-matched controls. Multivariable analysis was used to examine differences by service branch, rank, age, and deployment duration. Results: The steepest rise in disability incidence was observed among Vietnam veterans starting in the 1990s, around 20–30 years after deployment for most veterans. After 1994, when Statements of Principles were introduced to guide evaluation of disability claims, the hazard ratio for disability incidence was 1.53 (95% confidence interval, 1.32–1.77) compared with the prior period. By January 2011, after an average follow-up of 42.5 years, 69.7% (95% confidence interval, 69.4%–70.1%) of veterans had at least 1 war-related disability. Many veterans had multiple disabilities, with leading causes being eye and ear disorders (48.0%), mental health conditions (47.9%), and musculoskeletal disorders (18.4%). For specific categories of disability, relative risks for accepted claims among veterans compared with controls were highest for mental health disorders, at 22.9 (21.9–24.0) and lowest for injuries, at 1.5 (1.4–1.6) with a relative risk for any disability of 3.7 (3.7–3.8). Veterans with service of >1 year were 2.5 (2.2–2.7) times more likely to have a mental health disability than those who served war-related disability is associated with service history.

    The aim of this integrative review was to increase knowledge about parents' experiences of palliative care when their child is dying or has died due to illness using Whittemore and Knafl (2005) analysis process. Computerized databases were used to search the literature. Nine papers met the inclusion criteria. The analysis resulted in five categories: genuine communication, sincere relationships, respect as an expert, and alleviation of suffering and need of support, including 15 subcategories. Health professionals need education to provide high-quality pediatric palliative care. They especially need training concerning existential issues, and further studies need to be performed.

    Full Text Available Northern hemisphere peatlands are substantial carbon stores. However, recent climate change and human impacts (e.g., drainage and atmospheric nutrient deposition may trigger the emission of their stored carbon to the atmosphere. Biodiversity losses are also an important consequence of those changes. Therefore, there is a need to recognise these processes in space and time. Global change experiments are often conducted to improve our understanding of the potential responses of various ecosystems to global warming and drought. Most of the experiments carried out in peatlands are focused on carbon balance and nitrogen deposition. Nevertheless, it is still unclear how fast peatlands respond to temperature changes and water-table lowering in the continental climate setting. This is important because continental regions account for a significant proportion of all northern hemisphere peatlands. A combination of short-term and long-term approaches in a single research project is especially helpful because it facilitates the correct interpretation of experimental data. Here we describe the CLIMPEAT project - a manipulative field experiment in a Sphagnum-dominated peatland supported by a high-resolution multi-proxy palaeoecological study. The design of the field experiment (e.g., treatments, methodology and biogeographical setting are presented. We suggest it is beneficial to support field experiments with an investigation of past environmental changes in the studied ecosystem, as human impacts during the past 300 years have already caused substantial changes in ecosystem functioning which may condition the response in experimental studies.

    The short and long term stability of the Diomed 630 PDT laser with attached fiberoptic microlens was evaluated by means of integrating sphere, power meter and a calorimetric system. The calorimeter system was designed as a thermal mug with absorbing media (dye and water). Both the tip of the irradiation fiber and the detection probe of a thermocouple thermometer were positioned inside the dye solution and stirred during the measurements. The calorimetric system yielded measurement results consistent with the other two methods, and similar long term variations were observed by all methods. With an indicated laser power of 1 W, the detectors' readings ranged from 0.66 to 1.29 W. For short term stability study, the deviation of laser output assessed by integrating sphere, power meter and calorimetric system were 0.3%, 0.1% and 2.8% with long term deviations of 13%, 7% and 9% respectively. This wide variation in the laser output implies the needs to establish quality control procedures involving measurements pre and post PDT procedures. The calorimetric system has been demonstrated to be a powerful tool for clinical laser QA and maintenance of the calibration factor of the detectors used in this work.

    2014-08-01

    Full Text Available The European Council adopted the first EU Sustainable Development Strategy in 2001 (Gothenburg strategy, later on ambitiously updated in June 2006. The mainstreaming in the maritime domain is the Integrated Maritime Policy (IMP launched in 2007. This commentary provides a critical mid-term review on the status of IMP implementation, outlining the successes and failures of the implementation process from a governance perspective. The review focuses on the Integrated Maritime Surveillance, one of the pillars of the Integrated Maritime Policy, using this as a case study for evaluating the implementation progress against the stated objectives and the associated governance model. The outcome suggests that while the EU Integrated Maritime Policy has stimulated a lot of interest for a new maritime vision at EU level and has initiated important steps towards its implementation, including new maritime governance paradigm, so far it has failed to promote the necessary changes to boost the cooperative and sustainable environment it has claimed to do. In the particular case of the Integrated Maritime Surveillance, despite the strong political commitment of the European Commission and the considerable budget expenditure, the EU still has not been able to achieve the targeted Common Information Sharing Environment, failing an important milestone towards building sustainability in the maritime domain.

    2011-01-01

    Novel large scale research projects often require cooperation between various different project partners that are spread among the entire world. They do not only need huge computing resources, but also a reliable network to operate on. The Large Hadron Collider (LHC) at CERN is a representative example for such a project. Its experiments result in a vast amount of data, which is interesting for researchers around the world. For transporting the data from CERN to 11 data processing and storage sites, an optical private network (OPN) has been constructed. As the experiment data is highly valuable, LHC defines very high requirements to the underlying network infrastructure. In order to fulfil those requirements, the connections have to be managed and monitored permanently. In this paper, we present the integrated monitoring solution developed for the LHCOPN. We first outline the requirements and show how they are met on the single network layers. After that, we describe, how those single measurements can be comb...

    In April 2008, Japan launched a radical reform in regional health planning that emphasized the development of disease-oriented clinical care pathways. These 'inter-provider critical paths' have sought to ensure effective integration of various providers ranging among primary care practitioners, acute care hospitals, rehabilitation hospitals, long-term care facilities and home care. All 47 prefectures in Japan developed their Regional Health Plans pursuant to the guideline requiring that these should include at least four diseases: diabetes, acute myocardial infarction, cerebrovascular accident and cancer. To illustrate the care pathways developed, this paper describes the guideline referring to strokes and provides examples of the new Regional Health Plans as well as examples of disease-oriented inter-provider clinical paths. In particular, the paper examines the development of information sharing through electronic health records (EHR) to enhance effective integration among providers is discussed. Japan's reform in 2008 is unique in that the concept of 'disease-oriented regional inter-provider critical paths' was adopted as a national policy and all 47 prefectures developed their Regional Health Plans simultaneously. How much the new regional health planning policy has improved the quality and outcome of care remains to be seen and will be evaluated in 2013 after the five-year planned period of implementation has concluded. Whilst electronic health records appear to be a useful tool in supporting care integration they do not guarantee success in the application of an inter-provider critical path.

    Indoor air quality is vital to the health and comfort of people who live inside a controlled ecological life support system (CELSS) built for long-term space explorations. Here we measured aromatic hydrocarbons to assess their sources and health risks during a 4-person-180-day integrated experiment inside a CELSS with four cabins for growing crops, vegetables and fruits and other two cabins for working, accommodations and resources management. During the experiment, the average concentrations of benzene, ethylbenzene, m,p-xylenes and o-xylene were found to decrease exponentially from 7.91±3.72, 37.2±35.2, 100.8±111.7 and 46.8±44.1μg/m3 to 0.39±0.34, 1.4±0.5, 2.8±0.7 and 2.1±0.9μg/m3, with half-lives of 25.3, 44.8, 44.7 and 69.3days, respectively. Toluene to benzene ratios indicated emission from construction materials or furniture to be a dominant source for toluene, and concentrations of toluene fluctuated during the experiment largely due to the changing sorption by growing plants. The cancer and no-cancer risks based on exposure pattern of the crews were insignificant in the end of the experiment. This study also suggested that using low-emitting materials/furniture, growing plants and purifying air actively would all help to lower hazardous air pollutants inside CELSS. Broadly, the results would benefit not only the development of safe and comfort life support systems for space exploration but also the understanding of interactions between human and the total environment in closed systems.

    2013-03-01

    Full Text Available The innovative design of the next international Material Testing Reactor, the Jules Horowitz Reactor (JHR, induced the development of a new neutron and photon calculation formular HORUS3D/P&N, based on deterministic and stochastic codes and the European nuclear data library JEFF3.1.1. A new integral experiment, named the AMMON experiment, was designed in order to make the experimental validation of HORUS3D. The objectives of this experimental program are to calibrate the biases and uncertainties associated with the HORUS3D/N&P calculations for JHR safety and design calculations, but also the validation of some specific nuclear data (concerning mainly hafnium and beryllium isotopes. The experiment began in 2010 and is currently performed in the EOLE zero-power critical mock-up at CEA Cadarache. This paper deals with the first feedback of the AMMON experiments with 3D Monte Carlo TRIPOLI4©/JEFF3.1.1 calculations.

    Full Text Available Enteric neuropathies are severe gastrointestinal disorders with unsatisfactory outcomes. We aimed to investigate the potential of enteric neural stem cell therapy approaches for such disorders by transplanting mouse enteric neural crest cells (ENCCs into ganglionic and aganglionic mouse gut in vivo and analysing functional integration and long-term safety.Neurospheres generated from yellow fluorescent protein (YFP expressing ENCCs selected from postnatal Wnt1-cre;R26R-YFP/YFP murine gut were transplanted into ganglionic hindgut of wild-type littermates or aganglionic hindgut of Ednrbtm1Ywa mice (lacking functional endothelin receptor type-B. Intestines were then assessed for ENCC integration and differentiation using immunohistochemistry, cell function using calcium imaging, and long-term safety using PCR to detect off-target YFP expression.YFP+ ENCCs engrafted, proliferated and differentiated into enteric neurons and glia within recipient ganglionic gut. Transplanted cells and their projections spread along the endogenous myenteric plexus to form branching networks. Electrical point stimulation of endogenous nerve fibres resulted in calcium transients (F/F0 = 1.16 ± 0.01;43 cells, n = 6 in YFP+ transplanted ENCCs (abolished with TTX. Long-term follow-up (24 months showed transplanted ENCCs did not give rise to tumours or spread to other organs (PCR negative in extraintestinal sites. In aganglionic gut ENCCs similarly spread and differentiated to form neuronal and glial networks with projections closely associated with endogenous neural networks of the transition zone.Transplanted ENCCs successfully engrafted into recipient ganglionic and aganglionic gut showing appropriate spread, localisation and, importantly, functional integration without any long-term safety issues. This study provides key support for the development and use of enteric neural stem cell therapies.

    2012-04-01

    Many countries -- reflecting very different geographies, markets, and power systems -- are successfully managing high levels of variable renewable energy on the electric grid, including that from wind and solar energy. This study documents the diverse approaches to effective integration of variable renewable energy among six countries -- Australia (South Australia), Denmark, Germany, Ireland, Spain, and the United States (Western region-Colorado and Texas)-- and summarizes policy best practices that energy ministers and other stakeholders can pursue to ensure that electricity markets and power systems can effectively coevolve with increasing penetrations of variable renewable energy. Each country has crafted its own combination of policies, market designs, and system operations to achieve the system reliability and flexibility needed to successfully integrate renewables. Notwithstanding this diversity, the approaches taken by the countries studied all coalesce around five strategic areas: lead public engagement, particularly for new transmission; coordinate and integrate planning; develop rules for market evolution that enable system flexibility; expand access to diverse resources and geographic footprint of operations; and improve system operations. The ability to maintain a broad ecosystem perspective, to organize and make available the wealth of experiences, and to ensure a clear path from analysis to enactment should be the primary focus going forward.

    1996-01-01

    This study is a continuation of the summer research of 1995 NASA/ASEE Summer Faculty Fellowship Program. This effort is to provide the infrastructure of an integrated Virtual Reality (VR) environment for the International Space Welding Experiment (ISWE) Analytical Tool and Trainer and the Microgravity Science Glovebox (MSG) Analytical Tool study. Due to the unavailability of the MSG CAD files and the 3D-CAD converter, little was done to the MSG study. However, the infrastructure of the integrated VR environment for ISWE is capable of performing the MSG study when the CAD files become available. Two primary goals are established for this research. First, the essential peripheral devices for an integrated VR environment will be studied and developed for the ISWE and MSG studies. Secondly, the training of the flight crew (astronaut) in general orientation, procedures, and location, orientation, and sequencing of the welding samples and tools are built into the VR system for studying the welding process and training the astronaut.

    To assess the memory of various subdimensions of the birth experience in the second year postpartum, and to identify women in the first weeks postpartum at risk of developing a long-term negative memory. DESIGN, METHOD, OUTCOME MEASURES: New mothers' birth experience (BE) was assessed 48-96 hours postpartum (T1) by means of the SIL-Ger and the BBCI (perception of intranatal relationships); early postnatal adjustment (week 3 pp: T1(bis)) was also assessed. Then, four subgroups of women were defined by means of a cluster-analysis, integrating the T1/T1(bis) variables. To evaluate the memory of the BE, the SIL-Ger was again applied in the second year after childbirth (T2). First, the ratings of the SIL-Ger dimensions of T1 were compared to those at T2 in the whole sample. Then, the four subgroups were compared with respect to their ratings of the birth experience at T2 (correlations, ANOVAs and t-tests). In general, fulfillment, emotional adaptation, physical discomfort, and anxiety improve spontaneously over the first year postpartum, whereas in negative emotional experience, control, and time-going-slowly no shift over time is observed. However, women with a negative overall birth experience and a low level of perceived intranatal relationship at T1 run a high risk of retaining a negative memory in all of the seven subdimensions of the birth experience. Women at risk of developing a negative long-term memory of the BE can be identified at the time of early postpartum, when the overall birth experience and the perceived intranatal relationship are taken into account.

    This study aims at examining how factors relating to immigrants' experience in the host country affect psychological distress (PD). Specifically, we analyzed the association among socio-economic status (SES), integration in the labor market, specific immigration experience characteristics, and PD in a multi-ethnic sample of immigrant individuals residing in Lisbon, Portugal. Using a sample (n = 1375) consisting of all main immigrant groups residing in Portugal's metropolitan area of Lisbon, we estimated multivariable linear regression models of PD regressed on selected sets of socio-economic independent variables. A psychological distress scale was constructed based on five items (feeling physically tired, feeling psychologically tired, feeling happy, feeling full of energy, and feeling lonely). Variables associated with a decrease in PD are being a male (demographic), being satisfied with their income level (SES), living with the core family and having higher number of children (social isolation), planning to remain for longer periods of time in Portugal (migration project), and whether respondents considered themselves to be in good health condition (subjective health status). Study variables negatively associated with immigrants' PD were job insecurity (labor market), and the perception that health professionals were not willing to understand immigrants during a clinical interaction. The study findings emphasized the importance of labor market integration and access to good quality jobs for immigrants' psychological well-being, as well as the existence of family ties in the host country, intention to reside long term in the host country, and high subjective (physical) health. Our research suggests the need to foster cross-national studies of immigrant populations in order to understand the social mechanisms that transverse all migrant groups and contribute to lower psychological well-being.

    (weathered granitoids). Analysis of cumulative Na release indicated that plagioclase dissolution achieved steady state in 3 of the 4 fresh granitoids during the last decade of reaction. Surface-area normalized plagioclase dissolution rates exhibited a narrow range (0.95-1.26 10-13 moles m-2 s-1), in spite of significant stoichiometric differences (An0.21 to An0.50). Rates were an order of magnitude slower than previously reported in shorter duration experiments but generally 2-3 orders of magnitude faster than corresponding natural analogs. CrunchFlow simulations indicated that more than a hundredfold decrease in column flow rates would be required to produce near-saturation reaction affinities that would start to slow plagioclase weathering to real-world levels. Extending simulations to approximate long term weathering in naturally weathered profiles required additional decreases in the intrinsic plagioclase dissolution and kaolinite precipitation rates and relatively large decreases in the fluid flow rate, implying that exposure to reactive mineral surfaces is significantly limited in the natural environment compared to column experiments.

    Modelling experimental campaigns on the Orion laser at AWE, and developing a viable point-design for fast ignition (FI), calls for a multi-scale approach; a complete description of the problem would require an extensive range of physics which cannot realistically be included in a single code. For modelling the laser-plasma interaction (LPI) we need a fine mesh which can capture the dispersion of electromagnetic waves, and a kinetic model for each plasma species. In the dense material of the bulk target, away from the LPI region, collisional physics dominates. The transport of hot particles generated by the action of the laser is dependent on their slowing and stopping in the dense material and their need to draw a return current. These effects will heat the target, which in turn influences transport. On longer timescales, the hydrodynamic response of the target will begin to play a role as the pressure generated from isochoric heating begins to take effect. Recent effort at AWE [1] has focussed on the development of an integrated code suite based on: the particle in cell code EPOCH, to model LPI; the Monte-Carlo electron transport code THOR, to model the onward transport of hot electrons; and the radiation hydrodynamics code CORVUS, to model the hydrodynamic response of the target. We outline the methodology adopted, elucidate on the advantages of a robustly integrated code suite compared to a single code approach, demonstrate the integrated code suite's application to modelling the heating of buried layers on Orion, and assess the potential of such experiments for the validation of modelling capability in advance of more ambitious HEDP experiments, as a step towards a predictive modelling capability for FI.

    As approaches are sought for more efficient and democratized uses of non-model and expanded model genomics references, ease of integration of genomic feature datasets is especially desirable in multidisciplinary research communities. Valuable conclusions are often missed or slowed when researchers refer experimental results to a single reference sequence that lacks integrated pan-genomic and multi-experiment data in accessible formats. Association of genomic positional information, such as results from an expansive variety of next-generation sequencing experiments, with annotated reference features such as genes or predicted protein binding sites, provides the context essential for conclusions and ongoing research. When the experimental system includes polymorphic genomic inputs, rapid calculation of gene structural and protein translational effects of sequence variation from the reference can be invaluable. Here we present FEATnotator, a lightweight, fast and easy to use open source software program that integrates and reports overlap and proximity in genomic information from any user-defined datasets including those from next generation sequencing applications. We illustrate use of the tool by summarizing whole genome sequence variation of a widely used natural isolate of Arabidopsis thaliana in the context of gene models of the reference accession. Previous discovery of a protein coding deletion influencing root development is replicated rapidly. Appropriate even in investigations of a single gene or genic regions such as QTL, comprehensive reports provided by FEATnotator better prepare researchers for interpretation of their experimental results.

    2015-05-01

    The Essentials of Baccalaureate Education for Professional Nursing recognizes that with the increased globalization of health care, professional nurses have to be prepared to practice in multicultural environments and must possess the skills needed to provide culturally competent care. Thirty-five baccalaureate nursing students participated in a short-term course abroad to Jamaica over a period of 3 years. The impact of such an experience on ways of knowing was assessed in 20 participants, using a visual analog scale. Students believed that the short-term course abroad experience had a positive impact on their personal knowing and that they developed an understanding of a health care system different from their own, while reflecting on issues of social justice. Results provide evidence of the positive impact on short-term course abroad trips on students' ways of knowing. Critical to establishment of these experiences is evaluation of their merit through documentation of student learning outcomes. Copyright 2015, SLACK Incorporated.

    Fostered by and embedded in the general development of Information and Communication Technology (ICT) the evolution of Tsunami Early Warning Systems (TEWS) shows a significant development from seismic-centred to multi-sensor system architectures using additional sensors, e.g. sea level stations for the detection of tsunami waves and GPS stations for the detection of ground displacements. Furthermore, the design and implementation of a robust and scalable service infrastructure supporting the integration and utilisation of existing resources serving near real-time data not only includes sensors but also other components and systems offering services such as the delivery of feasible simulations used for forecasting in an imminent tsunami threat. In the context of the development of the German Indonesian Tsunami Early Warning System (GITEWS) and the project Distant Early Warning System (DEWS) a service platform for both sensor integration and warning dissemination has been newly developed and demonstrated. In particular, standards of the Open Geospatial Consortium (OGC) and the Organization for the Advancement of Structured Information Standards (OASIS) have been successfully incorporated. In the project Collaborative, Complex, and Critical Decision-Support in Evolving Crises (TRIDEC) new developments are used to extend the existing platform to realise a component-based technology framework for building distributed TEWS. This talk will describe experiences made in GITEWS, DEWS and TRIDEC while integrating legacy stand-alone systems and newly developed special-purpose software components into TEWS using different software adapters and communication strategies to make the systems work together in a corporate infrastructure. The talk will also cover task management and data conversion between the different systems. Practical approaches and software solutions for the integration of sensors, e.g. providing seismic and sea level data, and utilisation of special

    The changes in microbiological parameters of aggregates (1-2 mm) in typical chernozems under different land uses as dependent on the intensity and character of anthropogenic loads were studied with the help of the real-time polymerase chain reaction (PCR). The samples from the following long-term field experiments were examined: permanent black fallow, continuous cultivation of potato, 17-year-old unmanaged fallow after permanent black fallow, and annually mown reserved steppe. The soil samples were treated in two ways. In the first case, the samples were air-dried, sieved through the screens to separate aggregate fraction of 1-2 mm, and microbiological parameters were determined in this fraction. In the second case, the samples were frozen immediately after the sampling, and the aggregates of 1-2 mm were manually separated from the samples before the PCR analysis. It was shown that air-dry aggregates of chernozems could be used for the quantitative analysis of DNA of microbial community in comparative studies. According to the quantitative estimate of the content of DNA fragments from different phylogenetic groups, the bacterial community was most sensitive to the type of the soil use, and its restoration after the removal of extreme anthropogenic loads proceeded faster than that of other microorganisms. The content of archaeal DNA in the chernozem under the 17-year-old unmanaged fallow did not differ significantly from its content in the annually plowed chernozems. The changes in the content of micromycetal DNA related to anthropogenic load decrease were intermediate between changes in the contents of archaeal and bacterial DNA.

  1. CQESTR Simulation of Soil Organic Matter Dynamics in Long-term Agricultural Experiments across USA

    Soil organic matter (SOM) has important chemical (supplies nutrients, buffers and adsorbs harmful chemical compounds), biological (supports the growth of microorganisms and micro fauna), and physical (improves soil structure and soil tilth, stores water, and reduces surface crusting, water runoff) functions. The loss of 20 to 50% of soil organic carbon (SOC) from USA soils after converting native prairie or forest to production agriculture is well documented. Sustainable management practices for SOC is critical for maintaining soil productivity and responsible utilization of crop residues. As crop residues are targeted for additional uses (e.g., cellulosic ethanol feedstock) developing C models that predict change in SOM over time with change in management becomes increasingly important. CQESTR, pronounced "sequester," is a process-based C balance model that relates organic residue additions, crop management and soil tillage to SOM accretion or loss. The model works on daily time-steps and can perform long-term (100-year) simulations. Soil organic matter change is computed by maintaining a soil C budget for additions, such as crop residue or added amendments like manure, and organic C losses through microbial decomposition. Our objective was to simulate SOM changes in agricultural soils under a range of soil parent materials, climate and management systems using the CQESTR model. Long-term experiments (e.g. Champaign, IL, >100 yrs; Columbia, MO, >100 yrs; Lincoln, NE, 20 yrs) under various tillage practices, organic amendments, crop rotations, and crop residue removal treatments were selected for their documented history of the long-term effects of management practice on SOM dynamics. Simulated and observed values from the sites were significantly related (r2 = 94%, P < 0.001) with slope not significantly different from 1. Recent interest in crop residue removal for biofuel feedstock prompted us to address that as a management issue. CQESTR successfully simulated a

    The quantification of statistical dependencies in data of critical experiments and how to account for them properly in validation procedures has been discussed in the literature by various groups. However, these subjects are still an active topic in the Expert Group on Uncertainty Analysis for Criticality Safety Assessment (UACSA) of the OECDNEA Nuclear Science Committee. The latter compiles and publishes the freely available experimental data collection, the International Handbook of Evaluated Criticality Safety Benchmark Experiments, ICSBEP. Most of the experiments were performed as series and share parts of experimental setups, consequently leading to correlation effects in the results. The correct consideration of correlated data seems to be inevitable if the experimental data in a validation procedure is limited or one cannot rely on a sufficient number of uncorrelated data sets, e.g. from different laboratories using different setups. The general determination of correlations and the underlying covariance data as well as the consideration of them in a validation procedure is the focus of the following work. We discuss and demonstrate possible effects on calculated k{sub eff}'s, their uncertainties, and the corresponding covariance matrices due to interpretation of evaluated experimental data and its translation into calculation models. The work shows effects of various modeling approaches, varying distribution functions of parameters and compares and discusses results from the applied Monte-Carlo sampling method with available data on correlations. Our findings indicate that for the reliable determination of integral experimental covariance matrices or the correlation coefficients a detailed study of the underlying experimental data, the modeling approach and assumptions made, and the resulting sensitivity analysis seems to be inevitable. Further, a Bayesian method is discussed to include integral experimental covariance data when estimating an

    In the 2016 fiscal year the Ministry of Land, Infrastructure, Transport and Tourism of Japan started a program integrating construction and ICT in earthwork and concrete placing. The new program named "i-Construction" focusing on productivity improvement adopts such new technologies as UAV photogrammetry and TLS. We report a field experiment to investigate whether the procedures of UAV photogrammetry and TLS following the standards for "i-Construction" are feasible or not. In the experiment we measured an embankment of about 80 metres by 160 metres immediately after earthwork was done on the embankment. We used two sets of UAV and camera in the experiment. One is a larger UAV enRoute Zion QC730 and its onboard camera Sony α6000. The other is a smaller UAV DJI Phantom 4 and its dedicated onboard camera. Moreover, we used a terrestrial laser scanner FARO Focus3D X330 based on the phase shift principle. The experiment results indicate that the procedures of UAV photogrammetry using a QC730 with an α6000 and TLS using a Focus3D X330 following the standards for "i-Construction" would be feasible. Furthermore, the experiment results show that UAV photogrammetry using a lower price UAV Phantom 4 was unable to satisfy the accuracy requirement for "i-Construction." The cause of the low accuracy by Phantom 4 is under investigation. We also found that the difference of image resolution on the ground would not have a great influence on the measurement accuracy in UAV photogrammetry.

    Although chemotherapy and radiation treatment have contributed to increased survivorship, treatment-induced brain injury has been a concern when examining long-term intellectual outcomes of survivors. Specifically, disruption of brain white matter integrity and its relationship to intellectual outcomes in adult survivors of childhood brain tumors needs to be better understood. Fifty-four participants underwent diffusion tensor imaging in addition to structural MRI and an intelligence test (IQ). Voxel-wise group comparisons of fractional anisotropy calculated from DTI data were performed using Tract Based Spatial Statistics (TBSS) on 27 survivors (14 treated with radiation with and without chemotherapy and 13 treated without radiation treatment on average over 13 years since diagnosis) and 27 healthy comparison participants. Whole brain white matter fractional anisotropy (FA) differences were explored between each group. The relationships between IQ and FA in the regions where statistically lower FA values were found in survivors were examined, as well as the role of cumulative neurological factors. The group of survivors treated with radiation with and without chemotherapy had lower IQ relative to the group of survivors without radiation treatment and the healthy comparison group. TBSS identified white matter regions with significantly different mean fractional anisotropy between the three different groups. A lower level of white matter integrity was found in the radiation with or without chemotherapy treated group compared to the group without radiation treatment and also the healthy control group. The group without radiation treatment had a lower mean FA relative to healthy controls. The white matter disruption of the radiation with or without chemotherapy treated survivors was positively correlated with IQ and cumulative neurological factors. Lower long-term intellectual outcomes of childhood brain tumor survivors are associated with lower white matter integrity

    Generally, solid waste handling and management are performed by municipality or local authority. In most of developing countries, local authorities suffer from serious solid waste management (SWM) problems and insufficient data and strategic planning. Thus it is important to develop robust solid waste generation forecasting model. It helps to proper manage the generated solid waste and to develop future plan based on relatively accurate figures. In Malaysia, solid waste generation rate increases rapidly due to the population growth and new consumption trends that characterize the modern life style. This paper aims to develop monthly solid waste forecasting model using Autoregressive Integrated Moving Average (ARIMA), such model is applicable even though there is lack of data and will help the municipality properly establish the annual service plan. The results show that ARIMA (6,1,0) model predicts monthly municipal solid waste generation with root mean square error equals to 0.0952 and the model forecast residuals are within accepted 95% confident interval.

    Full Text Available A short-term, pulse injection tracer experiment conducted in fractured quartzitic sandstone at Kukuan, Taiwan was analyzed. Tracer transport at the test site was dominated by advection but a specific attenuation mechanism leading to breakthrough curve (BTC tailing also seemed to exist. Matrix diffusion was hypothesized as the transport mechanism that results in the tailing. This hypothesis was proved by comparing the field BTC with numerical simulation results obtained by the general-purpose flow/transport simulator, TOUGH2, based on a single-fracture conceptual model. Due to the lack of accuracy of estimating the interporosity flux by the conventional double porosity model (DPM, TOUGH2 was incorporated with the multiple interacting continua (MINC scheme to simulate the transient characteristics of the interporosity flux. In MINC, rock matrix is discretized as a series of continua according to the perpendicular distance from the fracture that adjoins the matrix. The closer the rock matrix is to the fracture, the finer the rock matrix is discretized. This concept is fundamentally different from DPM in that rock matrix is no longer treated as a single continuum. Simulation results by TOUGH2-MINC have successfully reproduced the observed BTC tailing even under the dominating advection effect. Sensitivity studies showed that TOUGH2-MINC is sensitive to parameters including fracture aperture (2b, matrix porosity (nm and effective molecular diffusion coefficient in matrix (Dm. If 2b, nm , Dm , are respectively 200 _ 2%, 10-11 m2 s -1, and if hydrodynamic dispersion coefficient (D is 1.69 _ m2 s -1, TOUGH2-MINC result can well fit the field BTC. Furthermore, the importance of matrix diffusion was verified by fitting the field BTC with analytical solutions that either neglect matrix diffusion or consider the mass exchange between mobile and immobile zones within the fracture as the attenuation transport mechanism.

    Community advisory committees (CACs) increasingly are formed to cultivate partnerships between researchers and communities. This article details the processes used to recruit CAC members, the purpose and structure of the committees, members' motivation to participate, and examples of member input and influence. In-depth interviews, meeting notes, and partners' reflections were synthesized to identify key lessons regarding establishing and sustaining effective CACs. Findings highlight the need for partner agreement on the role of CACs, structured meeting procedures, intentional integration of CAC input into project activities, and training on sharing research information with the community. CAC members' expertise regarding indigenous culture and experiences increased the project relevance for workers and strengthened research and intervention efforts. Members also reported greater knowledge of safety, health, and workers' rights, and increased confidence to share information. This influence extends beyond the project and contributes to sustained change among CAC members and in the participating communities.

    In this paper, the existing operational procedures applicable to wind and renewable generation in Spain are presented. These include remote control of renewable generators and their interaction with the TSO's Control Centre: energy production forecast and market integration, and voltage and reactive power control. Acciona Energia, as one of the largest operator and owner of renewable assets in Spain (particularly wind power plants), hat been a major player in the implementation of measures to comply with these procedures. For instance, it has worked closely with the TSO and the wind sector to help formulating Grid Code requirements, it has designed new wind turbine technologies to fulfil them and it has deployed innovative solutions to adapt older wind generators and plants to new standards (retrofitting). Acciona's experiences and technical solutions to these challenges are thoroughly discussed. (orig.)

    Having a modern application capable to automatically collect and process data from users, based on information and lifestyle answers is one of current challenges for researchers and medical science. The purpose of the current study is to integrate user experience design (UXD) in a cloud-based medical application to improve patient safety, quality of care and organizational efficiency. The process consists of collecting traditional and new data from patients and users using online questionnaires. A questionnaire dynamically asks questions about the user's current diet and lifestyle. After the user will introduce the data, the application will formulate a presumptive nutritional plan and will suggest different medical recommendations regarding a healthy lifestyle, and calculates a risk factor for diseases. This software application, by design and usability will be an efficient tool dedicated for fitness, nutrition and health professionals.

    2010-05-01

    An easily on-site reconfigurable multiple binary integrator for millimeter radar experiments has been constructed of static random access memories, an eight bit microcontroller, and high speed video operational amplifiers. The design uses a raw comparator path and two adjustable m-out-of-n chains in a wired-OR configuration. Standard high speed memories allow the use of pulse widths below 100 ns. For eight pulse repetition intervals it gives a maximum improvement of 6.6 dB for stationary low-level target echoes. The doubled configuration enhances the capability against fluctuating targets. Because of the raw comparator path, also single return pulses of relatively high amplitude are processed.

    2009-09-01

    Full Text Available Abstract Background Knowledge of subcellular localization of proteins is crucial to proteomics, drug target discovery and systems biology since localization and biological function are highly correlated. In recent years, numerous computational prediction methods have been developed. Nevertheless, there is still a need for prediction methods that show more robustness and higher accuracy. Results We extended our previous MultiLoc predictor by incorporating phylogenetic profiles and Gene Ontology terms. Two different datasets were used for training the system, resulting in two versions of this high-accuracy prediction method. One version is specialized for globular proteins and predicts up to five localizations, whereas a second version covers all eleven main eukaryotic subcellular localizations. In a benchmark study with five localizations, MultiLoc2 performs considerably better than other methods for animal and plant proteins and comparably for fungal proteins. Furthermore, MultiLoc2 performs clearly better when using a second dataset that extends the benchmark study to all eleven main eukaryotic subcellular localizations. Conclusion MultiLoc2 is an extensive high-performance subcellular protein localization prediction system. By incorporating phylogenetic profiles and Gene Ontology terms MultiLoc2 yields higher accuracies compared to its previous version. Moreover, it outperforms other prediction systems in two benchmarks studies. MultiLoc2 is available as user-friendly and free web-service, available at: http://www-bs.informatik.uni-tuebingen.de/Services/MultiLoc2.

    To say that someone possesses integrity is to claim that that person is almost predictable about responses to specific situations, that he or she can prudentially judge and to act correctly. There is a closed interrelationship between integrity and autonomy, and the autonomy rests on the deeper moral claim of all humans to integrity of the person. Integrity has two senses of significance for medical ethic: one sense refers to the integrity of the person in the bodily, psychosocial and intellectual elements; and in the second sense, the integrity is the virtue. Another facet of integrity of the person is la integrity of values we cherish and espouse. The physician must be a person of integrity if the integrity of the patient is to be safeguarded. The autonomy has reduced the violations in the past, but the character and virtues of the physician are the ultimate safeguard of autonomy of patient. A field very important in medicine is the scientific research. It is the character of the investigator that determines the moral quality of research. The problem arises when legitimate self-interests are replaced by selfish, particularly when human subjects are involved. The final safeguard of moral quality of research is the character and conscience of the investigator. Teaching must be relevant in the scientific field, but the most effective way to teach virtue ethics is through the example of the a respected scientist.

    Establishing improved spectrophotometric standards is important for a broad range of missions and is relevant to many astrophysical problems. Systematic errors associated with astrophysical data used to probe fundamental astrophysical questions, such as SNeIa observations used to constrain dark energy theories, now exceed the statistical errors associated with merged databases of these measurements. ACCESS, “Absolute Color Calibration Experiment for Standard Stars”, is a series of rocket-borne sub-orbital missions and ground-based experiments designed to enable improvements in the precision of the astrophysical flux scale through the transfer of absolute laboratory detector standards from the National Institute of Standards and Technology (NIST) to a network of stellar standards with a calibration accuracy of 1% and a spectral resolving power of 500 across the 0.35‑1.7μm bandpass. To achieve this goal ACCESS (1) observes HST/ Calspec stars (2) above the atmosphere to eliminate telluric spectral contaminants (e.g. OH) (3) using a single optical path and (HgCdTe) detector (4) that is calibrated to NIST laboratory standards and (5) monitored on the ground and in-flight using a on-board calibration monitor. The observations are (6) cross-checked and extended through the generation of stellar atmosphere models for the targets. The ACCESS telescope and spectrograph have been designed, fabricated, and integrated. Subsystems have been tested. Performance results for subsystems, operations testing, and the integrated spectrograph will be presented. NASA sounding rocket grant NNX17AC83G supports this work.

    Zhang, Y. H.; Hu, M.; Zhong, L. J.; Wiedensohler, A.; Liu, S. C.; Andreae, M. O.; Wang, W.; Fan, S. J.

    The aims of the Program of Regional Integrated Experiments on Air Quality over Pearl River Delta of China 2004 (PRIDE-PRD2004) were to characterize in depth the pollution, and to improve the understanding of the chemical and radiative processes in the atmosphere of Pearl River Delta (PRD) in South-Eastern China. This comprehensive program integrated ground-base in situ measurements, vertical observations (including aircraft) and model simulations. The intensive field campaign was conducted from 4 October to 5 November 2004 at two super-sites: an urban site in Guangzhou city (23.13°N, 113.26°E) and a non-urban site at Xinken (22.61°N, 113.59°E). They were coordinated with concurrent meteorological observations as well as measurements at stations of a regional monitoring network. Quality control and quality assurances, application of closure studies and observation-based modeling were the key elements of the research strategies for the PRIDE-PRD2004 campaign. Knowledge and understanding of the important issues, including 3-D distribution of air pollution, ozone formation process and its control strategies, sources of volatile organic compounds, chemical and physical characteristics and radiative properties of aerosols, and the important role of nitrous acid atmospheric chemistry, have been improved substantially by this study.

    This article reports on data from a qualitative interview study that sought to understand the experiences, choices and actions of children and young people undergoing surgery for a long-term condition and that of their parents. Using the concept of biography the article examines how the biographies of children, young people and their parents can be influenced by surgery and the ongoing management of a long-term continence condition. This article challenges previous work that characterises the presence of a condition from birth as a continuous and normal part of the illness experiences of these patients. Although this may be the case in some instances, children, young people and their parents can experience diverse and changing experiences associated with ongoing condition management as well as surgery. Biographical continuity, enrichment and disruption are all relevant concepts for such patients living with a long-term continence condition. These can be influenced by their previous experiences of their condition, their expectations, and dynamics with parents, including changes associated with development and the increasing independence of young people. © 2013 The Authors.

    Full Text Available Abstract Background This study aims to describe the development, testing and optimization of a new standard instrument, the Consumer Quality Index (CQ-index® Long-term Care, for measuring client experiences with long-term care in the Netherlands. Methods Three versions of the CQ-index questionnaires and protocols for study sampling and data collection were developed, designed for interviews with residents of nursing or residential care homes and postal surveys among representatives of psychogeriatric residents and homecare clients. From July to November 2006 a pilot study was conducted among 2,697 clients of 68 nursing or residential care homes, 2,164 representatives of clients in 57 psychogeriatric care institutions, and 1,462 clients of 19 homecare organizations. We performed psychometric analyses and descriptive analyses, and evaluated the pilot study. Results The pilot study showed the feasibility and usability of the instruments, supported the multidimensionality of the questionnaires and showed first findings on client experiences and possibilities for quality improvement. Nine scales applied to all care settings: shared decision making, attitude and courtesy, information, body care, competence and safety of care, activities, autonomy, mental well-being, and availability of personnel. The pilot resulted in three optimized questionnaires and recommendations for nationwide implementation. Conclusions The CQ-index® Long-term Care provides a good basis to investigate the quality of nursing homes, residential care homes and homecare from the clients' perspective. This standardized instrument enables a nationwide comparison of the quality of long-term care for the purpose of transparency and quality assurance.

    One important aspect in long-term safety assessment is related to radionuclide transport in geologic formations. In order to assess its consequences over assessment periods of one million years numerical models describing flow and transport are applied. Sorption on mineral surfaces is the most relevant process retarding radionuclide transport. On the one hand an increased transport time might cause a decrease in radionuclide concentration by radioactive decay. On the other hand it might increase concentrations of dose-relevant daughter nuclides in decay chains. In order to treat the radionuclide sorption processes in natural systems close to reality the so-called smart K{sub d}-concept is implemented into the transport program r{sup 3}t, which is applied to large model areas and very long time scales in long-term safety assessment. In the first stage this approach is developed for a typical sedimentary system covering rock salt and clay formations in Northern Germany. The smart K{sub d}-values are based on mechanistic surface complexation models (SCM), varying in time and space and de-pending on the actual geochemical conditions, which might change in the future e. g. due to the impact of climate changes. The concept developed and introduced here is based on a feasible treatment of the most relevant geochemical parameters in the transport code as well as on a matrix of smart K{sub d}-values calculated in dependence on these parameters. The implementation of the concept comprises the selection of relevant elements and minerals to be considered, an experimental program to fill data gaps of the thermody-namic sorption database, an uncertainty and sensitivity analysis to identify the most important environmental parameters influencing sorption of long-term relevant radionu-clides, the creation of a matrix with K{sub d}-values dependent on the selected environmental parameters, and the development and realisation of the conceptual model for treatment of temporal and

    Undergraduate medical education is moving from traditional disciplinary basic science courses into more integrated curricula. Integration models based on organ systems originated in the 1950s, but few longitudinal studies have evaluated their effectiveness. This article outlines the development and implementation of the Organic and Functional Systems (OFS) courses at the University of Minho in Portugal, using evidence collected over 10 years. It describes the organization of content, student academic performance and acceptability of the courses, the evaluation of preparedness for future courses and the retention of knowledge on basic sciences. Students consistently rated the OFS courses highly. Physician tutors in subsequent clinical attachments considered that students were appropriately prepared. Performance in the International Foundations of Medicine examination of a self-selected sample of students revealed similar performances in basic science items after the last OFS course and 4 years later, at the moment of graduation. In conclusion, the organizational and pedagogical approaches of the OFS courses achieve high acceptability by students and result in positive outcomes in terms of preparedness for subsequent training and long-term retention of basic science knowledge.

    We study the fluid inclusion of both Lennard-Jones (LJ) particles and particles with competing interaction ranges--short range attractive and long range repulsive (SALR)--in a disordered porous medium constructed as a controlled pore glass in two dimensions. With the aid of a full two-dimensional Ornstein-Zernike approach, complemented by a Replica Ornstein-Zernike integral equation, we explicitly obtain the spatial density distribution of the fluid adsorbed in the porous matrix and a good approximation for the average fluid-matrix correlations. The results illustrate the remarkable differences between the adsorbed LJ and SALR systems. In the latter instance, particles tend to aggregate in clusters which occupy pockets and bays in the porous structure, whereas the LJ fluid uniformly wets the porous walls. A comparison with Molecular Dynamics simulations shows that the two-dimensional Ornstein-Zernike approach with a Hypernetted Chain closure together with a sensible approximation for the fluid-fluid correlations can provide an accurate picture of the spatial distribution of adsorbed fluids for a given configuration of porous material.

    By employing an integrated x-ray instrument on a future Mars mission, data obtained will greatly augment those returned by Viking; details characterizing the past and present environment on Mars and those relevant to the possibility of the origin and evolution of life will be acquired. A combined x-ray fluorescence/x-ray diffraction (XRF/XRD) instrument was breadboarded and demonstrated to accommodate important exobiology and geology experiment objectives outlined for MESUR and future Mars missions. Among others, primary objectives for the exploration of Mars include the intense study of local areas on Mars to establish the chemical, mineralogical, and petrological character of different components of the surface material; to determine the distribution, abundance, and sources and sinks of volatile materials, including an assessment of the biologic potential, now and during past epoches; and to establish the global chemical and physical characteristics of the Martian surface. The XRF/XRD breadboard instrument identifies and quantifies soil surface elemental, mineralogical, and petrological characteristics and acquires data necessary to address questions on volatile abundance and distribution. Additionally, the breadboard is able to characterize the biogenic element constituents of soil samples providing information on the biologic potential of the Mars environment. Preliminary breadboard experiments confirmed the fundamental instrument design approach and measurement performance.

    Gazey, R.; Salman, S. K.; Aklil-D'Halluin, D. D.

    This paper aims to share the field application experience related to the development of an innovative stand-alone sustainable energy system known as the PURE project. The PURE project has been developed alongside a Knowledge Transfer Partnership (KTP) scheme, which is supported by the UK Department of Trade and Industry and executed by siGEN in collaboration with The Robert Gordon University. The system has been constructed within an industrial estate on the island of Unst in Shetland, 200 miles north of the Scottish mainland. The energy system now supplies five business properties with clean reliable power and utilises wind turbine and hydrogen technology to provide a sustainable energy source. The stored hydrogen gas generated by the system is used as an energy source for periods when electrical demand within the business properties exceeds wind turbine production. The hydrogen is also utilised as a fuel source for transportation and as a transportable energy source for mobile power generation. The paper therefore gives a detailed description of the PURE project and discusses the field experience accumulated during the development and installation of the system. It also shares a number of practical issues that had to be overcome during its integration and operation. The installation of the PURE project has resulted in a number of unexpected conclusions being identified and marks a significant step forward in the accessible deployment of this technology for community use.

    Predictions of climate-related shifts in species ranges have largely been based on correlative models. Due to limitations of these models, there is a need for more integration of experimental approaches when studying impacts of climate change on species distributions. Here, we used controlled experiments to identify physiological thresholds that control poleward range limits of three species of mangroves found in North America. We found that all three species exhibited a threshold response to extreme cold, but freeze tolerance thresholds varied among species. From these experiments, we developed a climate metric, freeze degree days (FDD), which incorporates both the intensity and the frequency of freezes. When included in distribution models, FDD accurately predicted mangrove presence/absence. Using 28 years of satellite imagery, we linked FDD to observed changes in mangrove abundance in Florida, further exemplifying the importance of extreme cold. We then used downscaled climate projections of FDD to project that these range limits will move northward by 2.2-3.2 km yr(-1) over the next 50 years. © 2014 John Wiley & Sons Ltd.

    The objective of our study was to determine whether infants with cystic fibrosis who developed exocrine pancreatic insufficiency in early infancy would tolerate long-term treatment with ZENPEP (pancrelipase) delayed-release capsules, containing 3000 US Pharmacopeia units of lipase/capsule, and demonstrate consistent long-term growth. The most common treatment-emergent adverse events were diarrhea, vomiting, and constipation (mild or moderate). At study completion, median weight-for-age percentiles increased from 22nd to 49th, median length-for-age percentiles increased from 36.5th to 42nd, and median weight-for-length percentiles increased from 41.5th to 55.5th. Long-term treatment (up to 12 months) of infants with exocrine pancreatic insufficiency owing to cystic fibrosis with ZENPEP was well tolerated and associated with improved growth parameters. This is the first long-term study of pancreatic enzyme replacement therapy conducted in this patient population.

    Global sea surface temperature (SST) anomalies have an inherent effect on vegetation dynamics and precipitation processes throughout the continental United States (U.S.). SST variations have been correlated with precipitation patterns via ocean-atmospheric interactions known as climate teleconnections. Prior research has demonstrated that understanding excitation mechanisms of the teleconnection patterns can be instrumental for climate prediction across a wide region at sub-continental scales, yet these studies tend to have large uncertainties in estimates by assuming linearity when examining teleconnection signals. The co-existence of non-stationary and nonlinear signals embedded in SST anomalies makes the identification of the teleconnection patterns difficult at the local scale. This study explores the short-term (10-year) frequencies (i.e., interannual and seasonal ) embedded in the non-stationary teleconnection signals between SST at the North Atlantic and North Pacific oceans and the responses of terrestrial greenness and precipitation along multiple pristine sites in northeast U.S., including (1) White Mountain National Forest - Pemigewasset Wilderness, (2) Green Mountain National Forest - Lye Brook Wilderness, and (3) Adirondack State Park - Siamese Ponds Wilderness. Each site was selected to avoid anthropogenic influences that may otherwise mask climate teleconnection signals. Lagged pixel-wise linear teleconnection analysis based on remote sensing satellite images across anomalous global SST datasets found significant correlation regions between SST and these terrestrial sites. With the aid of wavelet analyses including continuous wavelet transform, cross-wavelet analysis, and wavelet coherency analysis, nonlinear and non-stationary signals exhibit salient covariations at biennial and triennial frequencies between terrestrial responses and SST anomalies across oceanic regions in agreement with the El Nino Southern Oscillation (ENSO) and North Atlantic

    Antibody-mediated rejection (AMR) continues to pose a serious challenge in renal transplantation with potentially devastating consequences. Treatment options for this condition include plasmapheresis, high-dose intravenous immunoglobulin (IVIG), plasmapheresis with low-dose IVIG, and the use of rituximab (anti-CD20 chimeric antibody). We previously reported on the short-term outcome of plasmapheresis as a rescue therapy for AMR in our centre. We now report on the long-term follow up.

  10. Integrity of the Human Faecal Microbiota following Long-Term Sample Storage.

    Elahe Kia

    Full Text Available In studies of the human microbiome, faecal samples are frequently used as a non-invasive proxy for the study of the intestinal microbiota. To obtain reliable insights, the need for bacterial DNA of high quality and integrity following appropriate faecal sample collection and preservation steps is paramount. In a study of dietary mineral balance in the context of type 2 diabetes (T2D, faecal samples were collected from healthy and T2D individuals throughout a 13-day residential trial. These samples were freeze-dried, then stored mostly at -20°C from the trial date in 2000/2001 until the current research in 2014. Given the relative antiquity of these samples (~14 years, we sought to evaluate DNA quality and comparability to freshly collected human faecal samples. Following the extraction of bacterial DNA, gel electrophoresis indicated that our DNA extracts were more sheared than extracts made from freshly collected faecal samples, but still of sufficiently high molecular weight to support amplicon-based studies. Likewise, spectrophotometric assessment of extracts revealed that they were of high quality and quantity. A subset of bacterial 16S rRNA gene amplicons were sequenced using Illumina MiSeq and compared against publicly available sequence data representing a similar cohort analysed by the American Gut Project (AGP. Notably, our bacterial community profiles were highly consistent with those from the AGP data. Our results suggest that when faecal specimens are stored appropriately, the microbial profiles are preserved and robust to extended storage periods.

    The effect of motor imagery (MI) practice on isometric force development is well-documented. However, whether practicing MI during rest periods of physical training improves the forthcoming performance remains unexplored. We involved 18 athletes in a counterbalanced design including three physical training sessions scheduled over five consecutive days. Training involved 10 maximal isometric contractions against a force plate, with the elbow at 90°. During two sessions, we integrated MI practice (focusing on either muscle activation or relaxation) during the inter-trial rest periods. We measured muscle performance from force plate and electromyograms of the biceps brachii and anterior deltoideus. We continuously monitored electrodermal activity (EDA) to control sympathetic nervous system activity. MI of muscle activation resulted in higher isometric force as compared to both MI of muscle relaxation and passive recovery (respectively +2.1% and +3.5%). MI practice of muscle relaxation also outperformed the control condition (+1.9%). Increased activation of the biceps brachii was recorded under both MI practice conditions compared to control. Biceps brachii activation was similar between the two MI practice conditions, but electromyography revealed a marginal trend toward greater activation of the anterior deltoideus during MI practice of muscle activation. EDA and self-reports indicated that these effects were independent from physiological arousal and motivation. These results might account for priming effects of MI practice yielding to higher muscle activation and force performance. Present findings may be of interest for applications in sports training and neurologic rehabilitation. Copyright © 2015 IBRO. Published by Elsevier Ltd. All rights reserved.

    A study was made of the effects of a psychosocial rehabilitative program on the behavioral functioning of elderly chronically ill patients. High school students served as remotivation and socialization therapists in a supervised structured process designed to improve the quality of life for the participating nursing-home residents. The participants were 12 long-term patients whose ages ranged from 62 to 99 years (mean, 73.2 years). The effectiveness of the program was evaluated by means of the Sickness Impact Profile (SIP), a questionnaire designed to assess the effect of a physical illness on daily activities, psychosocial skills and mental status. The results demonstrated that the rehabilitative program had a significant impact on several dimensions of the lives of the participants. As a consequence of the interaction with the students, there was an increase in social interaction, a reduction in daytime sleeping and an increase in mobility. The results reported here extend the successful use of remotivation techniques to areas of overt behavioral functioning not previously assessed.

  14. Environmental management: integrating ecological evaluation, remediation, restoration, natural resource damage assessment and long-term stewardship on contaminated lands.

    Burger, Joanna

    2008-08-01

    Ecological evaluation is essential for remediation, restoration, and Natural Resource Damage Assessment (NRDA), and forms the basis for many management practices. These include determining status and trends of biological, physical, or chemical/radiological conditions, conducting environmental impact assessments, performing remedial actions should remediation fail, managing ecosystems and wildlife, and assessing the efficacy of remediation, restoration, and long-term stewardship. The objective of this paper is to explore the meanings of these assessments, examine the relationships among them, and suggest methods of integration that will move environmental management forward. While remediation, restoration, and NRDA, among others, are often conducted separately, it is important to integrate them for contaminated land where the risks to ecoreceptors (including humans) can be high, and the potential damage to functioning ecosystems great. Ecological evaluations can range from inventories of local plants and animals, determinations of reproductive success of particular species, levels of contaminants in organisms, kinds and levels of effects, and environmental impact assessments, to very formal ecological risk assessments for a chemical or other stressor. Such evaluations can range from the individual species to populations, communities, ecosystems or the landscape scale. Ecological evaluations serve as the basis for making decisions about the levels and kinds of remediation, the levels and kinds of restoration possible, and the degree and kinds of natural resource injuries that have occurred because of contamination. Many different disciplines are involved in ecological evaluation, including biologists, conservationists, foresters, restoration ecologists, ecological engineers, economists, hydrologist, and geologists. Since ecological evaluation forms the basis for so many different types of environmental management, it seems reasonable to integrate management options

  15. Inter-organisational integration for rehabilitation in Sweden – variation in views on long-term goals

    Ulla Sandström

    2004-12-01

    Full Text Available Purpose: The aim was to study variation in views on long-term goals expressed by members in a project concerning rehabilitation of individuals in an area in mid Sweden. The organisations participating were the municipal social services, the county council's health care organisation, the governmental social insurance office, the national employment service and the national labour market institute. Theory: A number of different meanings of the concept of integration are accounted for and the background of inter-organisational rehabilitation in Sweden is described. Methods: Qualitative interviews using a semi-structured interview guide with altogether 20 leading representatives of the various organisations, all members of the Steering Committee of the project. The analysis consisted of two parts: an in-depth analysis using a phenomenographically inspired approach and qualitative content analysis. Results: Two main views regarding the goal of inter-organisational integration were identified in the in-depth analysis: Category A, which regards integration as a new approach to rehabilitation, and Category B, which regards integration as a way of rendering the existing organisations more efficient. The content analysis showed a wide variation in spontaneously mentioned topics e.g. on the task of the group. Conclusions and discussion: There exists a risk that divergent views in the Steering Committee concerning the future direction of the collaboration may send mixed messages providing uneven support for the professionals within the different organisations. The study points to the importance of having a common vision and common, well-defined goals at the outset of a collaborative project in order to support micro-level cooperation.

  16. Induced Neural Stem Cells Achieve Long-Term Survival and Functional Integration in the Adult Mouse Brain

    Full Text Available Differentiated cells can be converted directly into multipotent neural stem cells (i.e., induced neural stem cells [iNSCs]. iNSCs offer an attractive alternative to induced pluripotent stem cell (iPSC technology with regard to regenerative therapies. Here, we show an in vivo long-term analysis of transplanted iNSCs in the adult mouse brain. iNSCs showed sound in vivo long-term survival rates without graft overgrowths. The cells displayed a neural multilineage potential with a clear bias toward astrocytes and a permanent downregulation of progenitor and cell-cycle markers, indicating that iNSCs are not predisposed to tumor formation. Furthermore, the formation of synaptic connections as well as neuronal and glial electrophysiological properties demonstrated that differentiated iNSCs migrated, functionally integrated, and interacted with the existing neuronal circuitry. We conclude that iNSC long-term transplantation is a safe procedure; moreover, it might represent an interesting tool for future personalized regenerative applications.

    Transitioning from the primary caregiver to the visitor in a long-term care facility may be challenging for the caregiver; they are required to surrender their caring duties to the medical and nursing staff. The aim of this study was to explore the experiences of caregivers during their transition from day-to-day caregiver of a person with dementia to a visitor in a long-term care facility. This study utilised a qualitative descriptive design. Twenty caregivers of people with dementia were recruited from the one Aged Rehabilitation and Geriatric Evaluation and Management facility, located in Victoria, Australia. Semi-structured interviews were used to explore the caregiver's experiences. Interviews were analysed using thematic analysis. The interview data revealed that the participants were undergoing similar experiences. The findings revealed that it was difficult for the caregiver to transition to their new role of visitor; negative reactions of grief, loss of motivation and loneliness were also coupled with positive feelings of relief and the reassurance that their relative or friend would be well cared for and safe within the long-term care facility. The findings offer insight into the experiences felt by caregivers when their relative or friend with dementia is admitted to hospital. Implications of this study include the need to improve the transition process for the caregiver by allowing them to be involved in the decision-making process, keeping them informed of care decisions, and importantly, providing emotional support to help the caregiver positively adapt to this transition.

    Awareness and experiences of elder abuse have been researched as separate entities; this study examined the relationship between awareness of elder abuse, disclosure of abuse, and reporting of abuse among people aged 65 years or older. A national cross-sectional survey of a random sample of 2,012 community-dwelling older people was carried out in Ireland. People described their understanding of the term elder abuse followed by their experiences of mistreatment. Descriptive statistics and logistic regression were used with frequency, percentage, odds ratios (OR), and 95% confidence intervals (CI) presented. The prevalence of elder abuse, including stranger abuse, since 65 years of age was 5.9% (95% CI 4.6-7.3). Overall, 80% of the population demonstrated some understanding of the term elder abuse. Older people who experienced physical abuse (OR 5.39; 95% CI 2.31-12.5) and psychological abuse (OR 2.51; 95% CI 1.58-3.97) were significantly more likely than older people who had not experienced mistreatment to relate the term elder abuse to their personal experiences. There was no association between experiences of financial abuse or neglect and awareness of the term elder abuse. There was a relatively high level of awareness of the term elder abuse; however, a substantial proportion of people could not readily associate abusive behaviors within their personal lives with elder abuse. Public information campaigns need to move beyond simple awareness rising to enable people to bridge the gap between a theoretical understanding of elder abuse and recognizing inappropriate behavior in their own circumstances.

    We investigated the relationship between different kinds of target reports in a rapid serial visual presentation task, and their associated perceptual experience. Participants reported the identity of two targets embedded in a stream of stimuli and their associated subjective visibility. In our task, target stimuli could be combined together to form more complex ones, thus allowing participants to report temporally integrated percepts. We found that integrated percepts were associated with high subjective visibility scores, whereas reports in which the order of targets was reversed led to a poorer perceptual experience. We also found a reciprocal relationship between the chance of the second target not being reported correctly and the perceptual experience associated with the first one. Principally, our results indicate that integrated percepts are experienced as a unique, clear perceptual event, whereas order reversals are experienced as confused, similar to cases in which an entirely wrong response was given.

    This meta-synthesis aimed to improve understanding of user experience of older people, carers, and health providers; and care integration in the care of older people transitioning from hospital to home. Following our systematic search, we identified and synthesized 20 studies, and constructed a comprehensive framework. We derived four themes: (1) 'Who is taking care of what? Trying to work together"; (2) 'Falling short of the mark'; (3) 'A proper discharge'; and (4) 'You adjust somehow.' The themes that emerged from the studies reflected users' experience of discharge and transitional care as a social process of 'negotiation and navigation of independence (older people/carers), or dependence (health providers).' Users engaged in negotiation and navigation through the interrogative strategies of questioning, discussion, information provision, information seeking, assessment, and translation. The derived themes reflected care integration that facilitated, or a lack of care integration that constrained, users' experiences of negotiation and navigation of independence/dependence. © The Author(s) 2016.

    Full Text Available Aim: The aims of the study were to determine and compare the primary dentition caries experience and the variables that may influence the occurrence of caries, in preterm low birth weight and full term normal birth weight children aged one to six years. Settings and Design: A cross-sectional comparative study was conducted among 250 full term normal birth weight (FTNBW and 250 preterm low birth weight (PTLBW children one to six years, born in the two hospitals in Davangere: Bapuji Hospital and Chigatere Hospital. A purposive sampling was used to select the study group. Materials and Methods: Required and relevant information regarding demographic characteristics, feeding practices and oral hygiene practices were obtained. Dentition status and treatment need index (World Health Organization 1997 was used to record dental caries. Statistical analysis used: Chi-square test, Student′s t-test and ANalysis Of VAriance (ANOVA test were used for statistical analysis. Results: Statistically significant difference was observed in caries prevalence between PTLBW and FTNBW groups (P<0.05, however, the difference in mean Decayed, missing and filled teeth index (dmft was not statistically significant (P=0.30. Statistically significant differences were observed in caries experience between the two groups in relation to exclusive breast feeding for longer duration, i.e 7-12 months (P<0.05, bottle feeding habits (P<0.05 and sticky food consumption (P<0.01. Conclusions: A significant relationship was found between caries and PTLBW status though the difference in caries experience between the groups was not statistically significant, thus illustrating the higher caries risk in PTLBW children compared to FTNBW children.

    This paper is based on a conference presentation made during the inauguration of the Faculty of Dentistry, Kuwait University, as a World Health Organization Collaborating Centre for Primary Oral Health Care (POHC) on November 27-28, 2012. The aim of this paper is to review how the POHC approach has been integrated into the dental curriculum, sharing the Tanzanian experience as a case presentation from a developing country. The burden of oral diseases worldwide is high, and the current oral health workforce is inadequate to meet the challenges. Curative oral health care is very costly and not accessible to the poor and minorities. To tackle the problem, the POHC approach rooted in primary health care that emphasizes equity, community involvement, prevention, appropriate technology and a multi-sectorial approach was developed and has been operating for more than 3 decades now. Execution of a comprehensive POHC requires a trained oral health workforce mix with essential competencies. For this case study, a literature search was done using the search engines subscribed to by the library of Muhimbili University of Health and Allied Sciences, including PubMed, Cochrane, ScienceDirect and Scopus, Wiley-Blackwell Interscience, Sage and the Health InterNetwork Access to Research Initiative (HINARI) that gives access to Scirus and Google Scholar. Challenges are discussed with an emphasis more on addressing the common risk factors and determinants of oral health. Integration of the POHC approach in the dental curriculum for training a competent workforce is crucial in attaining better oral health. Resources are still a major challenge, and the impact of the POHC approach in the curriculum is yet to be evaluated. © 2013 S. Karger AG, Basel.

    This grant supported fundamental research into the characterization of flow parameters of relevance to the wind energy industry focused on offshore and the coastal zone. A major focus of the project was application of the latest generation of remote sensing instrumentation and also integration of measurements and numerical modeling to optimize characterization of time-evolving atmospheric flow parameters in 3-D. Our research developed a new data-constrained Wind Atlas for the Great Lakes, and developed new insights into flow parameters in heterogeneous environments. Four experiments were conducted during the project: At a large operating onshore wind farm in May 2012; At the National Renewable Energy Laboratory National Wind Technology Center (NREL NWTC) during February 2013; At the shoreline of Lake Erie in May 2013; and At the Wind Energy Institute of Canada on Prince Edward Island in May 2015. The experiment we conducted in the coastal zone of Lake Erie indicated very complex flow fields and the frequent presence of upward momentum fluxes and resulting distortion of the wind speed profile at turbine relevant heights due to swells in the Great Lakes. Additionally, our data (and modeling) indicate the frequent presence of low level jets at 600 m height over the Lake and occasions when the wind speed profile across the rotor plane may be impacted by this phenomenon. Experimental data and modeling of the fourth experiment on Prince Edward Island showed that at 10-14 m escarpment adjacent to long-overseas fetch the zone of wind speed decrease before the terrain feature and the increase at (and slightly downwind of) the escarpment is ~3–5% at turbine hub-heights. Additionally, our measurements were used to improve methods to compute the uncertainty in lidar-derived flow properties and to optimize lidar-scanning strategies. For example, on the basis of the experimental data we collected plus those from one of our research partners we advanced a new methodology to

    home births are quite rare and are not supported as part of mainstream health care services in most European countries. Women who choose home as the place of birth often do so because maternity services in hospitals do not offer the options that they want. The aim of the present study is to describe women's experiences of giving birth at home and to produce a comprehensive structure of meaning regarding giving birth at home. a phenomenological study based on analysis of open-interview transcripts using Colaizzi's approach. women who gave birth at home FINDINGS: women who have given birth at home experience having control over their own body, the care they are given, and the practical arrangements surrounding the birth. However, they also experience negative attitudes from other people about their decision to give birth at home, and challenges because of worries about how they and their baby will cope. During the birth women feel a sense of connection to their own body, which they trust to tell them what to do. They experience great happiness on successfully giving birth and feel connected to nature and the circle of life. Being able to celebrate with family members and be pampered by them after the birth made the women feel 'like queens'. women's experience of childbirth at home is one of having control over the birthing process and its environment. The main challenge is exposure to negative attitudes from others, including health care professionals. Overall, the experience was full of happiness and good feelings. We conclude that more attention should be paid to the quality of birth experiences and women's individual needs and wishes within maternity care provision. Copyright © 2017 Elsevier Ltd.

    This study investigates the functions of news media in shaping acculturation experiences of new economic and refugee immigrants in the Netherlands and Spain. Focus group data revealed that consumption of host country news media was mainly connected to immigrants’ deliberate strategies to assimilate the culture, politics and language of the host society, while exposure to transnational news was viewed in terms of strategies of integration in both countries. We also observed that participants’ educational background and language skills combined with their perceptions of the host country’s news have an impact on the use they make of news for assimilating and/or integrating into the host society. Finally, important sociopolitical conditions of the context influenced the ways participants use the news media in their process of acculturation. PMID:28579663

    How does a person's first experience with a foreign or unfamiliar food shape their long-term preference and behavior toward that food? To investigate this, 493 American veterans of World War II were surveyed about their preference for Japanese and Chinese food. Pacific veterans who experienced high levels of combat had a stronger dislike for these Asian foods than those Pacific veterans experiencing lower levels of combat. Consistent with expectations, combat experience for European veterans had no impact on their preference for Asian food. The situation in which one is initially exposed to an unfamiliar food may long continue to shape preferences.

    As advances in genomics make genome sequencing more affordable, the availability of new genome-based diagnostic and therapeutic strategies (i.e., personalized medicine) will increase. This wave will hit front-line physicians who may be faced with a plethora of patients' expectations of integrating genomic data into clinical care. The objective of this study was to elicit the preferences of physicians about regarding applying personalized medicine in their clinical practice as these strategies become available. Using a best-worst scaling (BWS) choice experiment, we estimated the relative importance of attributes that influence physicians' decision for using personalized medicine. Six attributes were included in the BWS: type of genetic tests, training for genetic testing, clinical guidelines, professional fee, privacy protection laws, and cost of genetic tests. A total of 197 physicians in British Columbia completed the experiment. Using latent class analysis (LCA), we explored the physicians' heterogeneities in preferences. "Type of genetic tests" had the largest importance, suggesting that the physicians' decision was highly influenced by the availability of genetic tests for patients' predisposition to diseases and/or drug response. "Training" and "guidelines" were the attributes with the next highest importance. LCA identified two classes of physicians. Relative to class 2, class 1 had a larger weight for the "type of genetic tests," but smaller weights for "professional fee" and "cost of tests." We measured relative importance of factors that affect the decision of physicians to incorporate personalized medicine in their practice. These results can be used to design the policies for supporting physicians and facilitating the use of personalized medicine in the future.

    Liu, Hong

    A 90-day bioregenerative life support experiment with three-member crew was carried out in the closed integrative experimental facility, LUNAR PALACE 1 regenerating basic living necessities and disposing wastes to provide life support for crew. It was composed of higher plant module, animal module, and waste treatment module. The higher plant module included wheat, chufa, pea, carrot and green leafy vegetables, with aim to satisfy requirement of 60% plant food and 100% O2 and water for crew. The yellow mealworm was selected as animal module to provide partial animal protein for crew, and reared on plant inedible biomass. The higher plant and yellow mealworm were both cultivated and harvested in the conveyor-type manner. The partial plant inedible biomass and human feces were mixed and co- fermented in the waste treatment module for preparation of soil-like substrate by bioconversion, maintaining gas balance and increasing closure degree. Meanwhile, in the waste treatment module, the water and partial nitrogen from human urine were recovered by physical-chemical means. Circulation of O2 and water as well as food supply from crops cultivated in the LUNAR PALACE 1 were investigated and calculated, and simultaneously gas exchange, mass flow among different components and system closure degree were also analyzed, respectively. Furthermore, the system robustness with respect to internal variation was tested and evaluated by sensitivity analysis of the aggregative index consisting of key performance indicators like crop yield, gaseous equilibrium concentration, microbial community composition, biogenic elements dynamics, etc., and comprehensively evaluating the operating state, to number change of crew from 2 to 4 during the 90-day closed experiment period.

    2005-08-01

    We introduce a tool for text mining, Dragon Plant Biology Explorer (DPBE) that integrates information on Arabidopsis (Arabidopsis thaliana) genes with their functions, based on gene ontologies and biochemical entity vocabularies, and presents the associations as interactive networks. The associations are based on (1) user-provided PubMed abstracts; (2) a list of Arabidopsis genes compiled by The Arabidopsis Information Resource; (3) user-defined combinations of four vocabulary lists based on the ones developed by the general, plant, and Arabidopsis GO consortia; and (4) three lists developed here based on metabolic pathways, enzymes, and metabolites derived from AraCyc, BRENDA, and other metabolism databases. We demonstrate how various combinations can be applied to fields of (1) gene function and gene interaction analyses, (2) plant development, (3) biochemistry and metabolism, and (4) pharmacology of bioactive compounds. Furthermore, we show the suitability of DPBE for systems approaches by integration with "omics" platform outputs. Using a list of abiotic stress-related genes identified by microarray experiments, we show how this tool can be used to rapidly build an information base on the previously reported relationships. This tool complements the existing biological resources for systems biology by identifying potentially novel associations using text analysis between cellular entities based on genome annotation terms. Thus, it allows researchers to efficiently summarize existing information for a group of genes or pathways, so as to make better informed choices for designing validation experiments. Last, DPBE can be helpful for beginning researchers and graduate students to summarize vast information in an unfamiliar area. DPBE is freely available for academic and nonprofit users at http://research.i2r.a-star.edu.sg/DRAGON/ME2/.

    Full Text Available In this paper, we investigate the impact of fixed term employment spells (fixed-term contracts and temporary work on the integration on the labour market (translated by the transition to a permanent contract for French school-leavers. We study, at the same time, the impact of three categories of determinants on the schoolleavers' integration on the labour market: individual's features, a first fixed-term employment spell and a later fixed-term employment episode. More precisely, by taking into account the fixed-term employment spell duration, we identify four possible trajectories and we examine if fixed term employment is a "stepping-stone" to permanent employment. In order to control for possible endogeneity biases, trivariate probit models are implemented on a sample of 11 303 individuals obtained from the French "Generation 98" survey.

  7. Adult-age inflammatory pain experience enhances long-term pain vigilance in rats.

    Directory of Open Access Journals (Sweden)

    Sheng-Guang Li

    Full Text Available Previous animal studies have illustrated a modulatory effect of neonatal pain experience on subsequent pain-related behaviors. However, the relationship between chronic pain status in adulthood and future pain perception remains unclear.In the current study, we investigated the effects of inflammatory pain experience on subsequent formalin-evoked pain behaviors and fear conditioning induced by noxious stimulation in adult rats. Our results demonstrated an increase of the second but not the first phase of formalin-induced pain behaviors in animals with a history of inflammatory pain that have recovered. Similarly, rats with persistent pain experience displayed facilitated acquisition and prolonged retention of pain-related conditioning. These effects of prior pain experience on subsequent behavior were prevented by repeated morphine administration at an early stage of inflammatory pain.These results suggest that chronic pain diseases, if not properly and promptly treated, may have a long-lasting impact on processing and perception of environmental threats. This may increase the susceptibility of patients to subsequent pain-related disorders, even when chronic pain develops in adulthood. These data highlight the importance of treatment of chronic pain at an early stage.

    It has been suggested that writing auditorily presented words at encoding involves distinctive translation processes between visual and auditory domains, leading to the formation of distinctive memory traces at retrieval. This translation effect leads to higher levels of recognition than the writing of visually presented words, a non-translation effect. The present research investigated whether writing and the other translation effect of vocalisation (vocalising visually presented words) would be present in tests of recall, recognition memory and whether these effects are based on the subjective experience of remembering or knowing. Experiment 1 found a translation effect in the auditory domain in recall, as the translation effect of writing yielded higher recall than both non-translation effects of vocalisation and silently hearing. Experiment 2 found a translation effect in the visual domain in recognition, as the translation effect of vocalisation yielded higher recognition than both non-translation effects of writing and silently reading. This translation effect was attributable to the subjective experience of remembering rather than knowing. The present research therefore demonstrates the beneficial effect of translation in both recall and recognition, with the effect of vocalisation in recognition being based on rich episodic remembering.

    Microalgae cultivation appears to be a promising technology for treating nutrient-rich effluents from anaerobic membrane bioreactors, as microalgae are able to consume nutrients from sewage without an organic carbon source, although the sulphide formed during the anaerobic treatment does have negative effects on microalgae growth. Short and long-term experiments were carried out on the effects of sulphide on a mixed microalgae culture. The short-term experiments showed that the oxygen production rate (OPR) dropped as sulphide concentration increased: a concentration of 5mgSL -1 reduced OPR by 43%, while a concentration of 50mgSL -1 came close to completely inhibiting microalgae growth. The long-term experiments revealed that the presence of sulphide in the influent had inhibitory effects at sulphide concentrations above 20mgSL -1 in the culture, but not at concentrations below 5mgSL -1 . These conditions favoured Chlorella growth over that of Scenedesmus. Copyright © 2017 Elsevier Ltd. All rights reserved.

  12. Improved detection of differentially expressed genes in microarray experiments through multiple scanning and image integration

    The variability of results in microarray technology is in part due to the fact that independent scans of a single hybridised microarray give spot images that are not quite the same. To solve this problem and turn it to our advantage, we introduced the approach of multiple scanning and of image integration of microarrays. To this end, we have developed specific software that creates a virtual image that statistically summarises a series of consecutive scans of a microarray. We provide evidence that the use of multiple imaging (i) enhances the detection of differentially expressed genes; (ii) increases the image homogeneity; and (iii) reveals false-positive results such as differentially expressed genes that are detected by a single scan but not confirmed by successive scanning replicates. The increase in the final number of differentially expressed genes detected in a microarray experiment with this approach is remarkable; 50% more for microarrays hybridised with targets labelled by reverse transcriptase, and 200% more for microarrays developed with the tyramide signal amplification (TSA) technique. The results have been confirmed by semi-quantitative RT–PCR tests. PMID:14627839

    The effectiveness of educational interventions for osteoarthritic patients undergoing total joint arthroplasty remains inconclusive. It is essential to understand the educational needs of these patients from their perspectives. The aim of this study was to systematically summarize and synthesize osteoarthritic patients' expectations and experiences in undergoing total joint arthroplasty to identify their educational needs. An integrative review was conducted. Twenty studies (13 qualitative and 7 quantitative), published between 2006 and 2016, were independently appraised by 2 reviewers using the Critical Appraisal Skills Programme checklist for qualitative studies and the Joanna Briggs Institute Critical Appraisal Tools for quantitative studies. Data were analysed using thematic analysis, and the findings were synthesized in a narrative summary. Six themes describing patients' preoperative and post-operative educational needs were identified: (1) preoperative anxiety, (2) unrealistic expectations of recovery, (3) post-operative pain, (4) regaining functional abilities, (5) physical and psychological sense of loss, and (6) lack of continuity of care. This review is the first to capture the osteoarthritic patients' educational needs from their perspectives. The biopsychosocial model can address the multidimensionality (biological, psychological, and social) of patients' educational needs. A robust infrastructure supporting interprofessional collaborative practice and continuity of care should be adopted to enhance current educational efforts. © 2018 John Wiley & Sons Australia, Ltd.

    The Cosmic Infrared Background ExpeRiment, CIBER-2, is a near-infrared rocket-borne instrument designed to conduct comprehensive multi-band measurements of extragalactic background light anisotropy on arcsecond to degree angular scales. Recent measurements of the near-infrared Extragalactic Background Light (EBL) anisotropy find excess spatial power above the level predicted by known galaxy populations at large angular scales. CIBER-2 is designed to make measurements of the EBL anisotropy with the sensitivity, spectral range, and spectral resolution required to disentangle the contributions to the EBL from various sources throughout cosmic history.CIBER-2 consists of a 28.5 cm Cassegrain telescope assembly, imaging optics, and cryogenics mounted aboard a sounding rocket. Two dichroic beam-splitters spectrally subdivide the incident radiation into three optical paths, which are further subdivided in two wavelength bands per path, for a total of six observational wavelength bands that span the optical to the near-infrared and produce six 1.2 by 2.4 degree images recorded by three 2048 x 2048 HAWAII-2RG detector arrays. A small portion of each detector is also dedicated to absolute spectrophotometric imaging provided by a linear-variable filter. The instrument has several novel cryogenic mechanisms, a cryogenically-cooled pop-up baffle that extends during observations to provide radiative shielding and an electromagnetic cold shutter. We provide an overview of the instrument and current integration.

    2007-12-01

    Full Text Available Introduction: One aspect of clinical integration involves case managers' tools and particularly the individualized service plan. Methods: We examined individualized service plan content and use in the PRISMA experiment. We analyzed 50 charts, and conducted and recorded interviews regarding individualized service plan use with all the case managers concerned (n=13. Results: Delays between starting case management and writing the individualized service plan were long and varied (0–596 days, mean: 117 days. During the interviews, the individualized service plan was described as the ‘last step’ once the active planning phase was over. The reasons for formulating plans were mainly administrative. From a clinical viewpoint, individualized service plans were used as memoranda and not to describe services (842 interventions not mentioned in the plans or needs (694 active problems not mentioned. Case managers felt uncomfortable with the individualized planning task and expected a tool more adapted to their needs. Conclusion: Although a majority of the case managers' charts contained an individualized service plan, implementation of this tool seems tenuous. Because of the discrepancy between the potential usefulness expected by case managers and their actual use, a working committee was created to develop proposals for modifying the instrument.

  16. Integrating Cognitive and Affective Dimensions of Pain Experience into Health Professions Education

    Directory of Open Access Journals (Sweden)

    Beth B Murinson

    2011-01-01

    Full Text Available Pain is prevalent in clinical settings, and yet it is relatively under-represented in the education of most students in the health professions. Because pain includes both sensory-discriminative and affective features, teaching students about pain presents unique challenges and opportunities. The present article describes the evolution of a new blueprint for clinical excellence that, among other competencies, incorporates a need for the emotional development of clinical trainees. The framework has been applied to the development and implementation of two new courses in pain. The first course is designed to provide a comprehensive foundation of medical knowledge regarding pain, while integratively introducing students to the affective dimensions of pain. The second course is designed to enhance students’ appreciation for the protean effects of pain through use of the humanities to represent medical experience. It is concluded that, to be most effective, fostering the emotional development of trainees in the health professions necessitates the incorporation of affect-focused learning objectives, educational tasks and assessment methods.

    Three Microwave Radiometers (two 3-channel and one 2-channel) were deployed in the Southern Appalachian Mountains in western North Carolina as part of the Integrated Precipitation and Hydrology Experiment (IPHEx), which was the first National Aeronautics and Space Administration (NASA) Global Precipitation Mission (GPM) Ground Validation (GV) field campaign after the launch of the GPM Core Satellite (Barros et al. 2014). The radiometers were used along with other instrumentation to estimate the liquid water content of low-level clouds and fog. Specifically, data from the radiometers were collected to help, with other instrumentation, to characterize fog formation, evolution, and dissipation in the region (by monitoring the liquid water path in the column) and observe the effect of that fog on the precipitation regime. Data were collected at three locations in the Southern Appalachians, specifically western North Carolina: a valley in the inner mountain region, a valley in the open mountain pass region, and a ridge in the inner region. This project contributes to the U.S. Department of Energy (DOE)’s Atmospheric Radiation Measurement (ARM) Climate Research Facility mission by providing in situ observations designed to improve the understanding of clouds and precipitation processes in complex terrain. The end goal is to use this improved understanding of physical processes to improve remote-sensing algorithms and representations of orographic precipitation microphysics in climate and earth system models.

    The Working Party on International Nuclear Data Evaluation Co-operation (WPEC) subgroup 29 (SG 29) was established to investigate an issue with the 235U capture cross-section in the energy range from 0.1 to 2.25 keV, due to a possible overestimation of 10% or more. To improve the 235U capture crosssection, a new 235U evaluation has been proposed by the Institut de Radioprotection et de Sûreté Nucléaire (IRSN) and the CEA, mainly based on new time-of-flight 235U capture cross-section measurements and recent fission cross-section measurements performed at the n_TOF facility from CERN. IRSN and CEA Cadarache were in charge of the thermal to 2.25 keV energy range, whereas the CEA DIF was responsible of the high energy region. Integral experiments showing a strong 235U sensitivity are used to assess the new evaluation, using Monte-Carlo methods. The keff calculations were performed with the 5.D.1 beta version of the MORET 5 code, using the JEFF-3.2 library and the new 235U evaluation, as well as the JEFF-3.3T1 library in which the new 235U has been included. The benchmark selection allowed highlighting a significant improvement on keff due to the new 235U evaluation. The results of this data testing are presented here.

    1997-08-01

    The present paper describes the analysis of integral experiments on stainless steel (SS) and SS/water shielding assemblies, irradiated with 14-MeV neutrons. The analysis is performed with the Monte Carlo transport code MCNP-4A and using the fusion evaluated nuclear data library (FENDL). The ratios of calculated over measured quantities are given and discussed for the validation of the FENDL library in view of its use in the design of the international thermonuclear experimental reactor (ITER). The analysis is also done using the European fusion file (EFF), versions 1 and 2, for comparison. The results show that these libraries can satisfactorily describe the features of the neutron and gamma radiation attenuation in large SS shields. Some trends are, however, found to underestimate the fast neutron flux (E>{approx}0.5 MeV) in deep locations, that may lead to a non-correct evaluation of damage parameters for structural components in the reactor design.

The keff calculations were performed with the 5.D.1 beta version of the MORET 5 code, using the JEFF-3.2 library and the new 235U evaluation, as well as the JEFF-3.3T1 library in which the new 235U has been included. The benchmark selection allowed highlighting a significant improvement on keff due to the new 235U evaluation. The results of this data testing are presented here.

    This study explored the eating experience in long-term survivors of head and neck cancer (HNC) ≥3 years post concurrent chemoradiation. Quality of life (QOL) and the meanings and perceptions survivors had as it related to the eating experience were explored. Purposive sampling was utilized; 10 long-term survivors of HNC participated in the study. A mixed-methods approach was used; exploratory qualitative research using content analysis and summary statistics was used to describe demographic and clinical characteristics and the Vanderbilt Head and Neck Symptom Survey version 2.0 scores (VHNSS 2.0). Four categories (psychological, social impact, functional status, and the current eating experience) containing 15 subthemes and 1 overarching theme (adaptation) emerged. Current health status, QOL, and QOL related to eating were viewed favorably despite the impact of treatment late effects on participants' daily lives. Adaptation and maladaptation in regard to food choice and downplaying of symptoms were recognized. Interviews as well as the VHNSS 2.0 scores indicated that xerostomia, mucosal sensitivity, swallowing difficulty, length of time required to eat, and dysgeusia remained problematic. Psychological, functional, and social losses associated with eating were identified. Participants modify or avoid foods that are challenging yet report enjoyment with eating. Challenges with eating were downplayed. Due to the potential negative nutritional and social implications of avoiding specific food/food groups, standard of care in long-term survivors of HNC should include assessment of the eating experience and functional challenges. Nutrition professional can help patients optimize dietary intake and the eating experience.

    The effect of long-term stagnation on copper corrosion by-product release and corrosion rates was studied in pipe-rigs according to the German standard DIN 50931, Part 1. The analysis of the water phase was supplemented by surface analysis of corrosion scales. Copper concentration during stagnation did not follow a solubility process. The characteristic curves obtained can be explained by subsequent copper release and copper refixation processes. Oxygen consumption can be described by the first-order kinetic rate law. The corrosion scales consisted of cuprite (Cu2O) and malachite (CuCO3 x Cu(OH)2). Malachite grew in well-defined crystals during stagnation, served as sink for dissolved copper and did not protect the pipe against corrosion attack. Copper concentrations measured after long-term stagnation (up to 122 h) correspond to the solubility of malachite in the testwater.

    Full Text Available Retrospective analysis was performed on 30 patients of skull defect who underwent surgical repair. Intraoperative and postoperative curative effect was evaluated on those patients, and the results showed that the incidence rate of intraoperative dura mater defect (P = 0.001, early postoperative complications [new epilepsy (P = 0.035 and effusion (P = 0.021] and late postoperative complications [foreign body sensation (P = 0.035 and dizziness and headache (P = 0.050] in long-term skull defect group were all higher than those in control group. In conclusion, surgical repair of long-term skull defect incurring high risk and various complications will not be an ideal management. Therefore, early surgical treatment for skull defect is suggested. DOI: 10.3969/j.issn.1672-6731.2015.12.016

    In marine environment, the antifouling properties against marine sessile organisms (algae, sea squirts, barnacles, etc.) were tested on various kinds of hydrogels in a long term. The results demonstrate that most hydrogels can ensure at least 2 months in marine environment. In particular, mechanically tough PAMPS/PAAm DN and PVA gels exhibited amazing antifouling activity against marine sessile organisms, especially barnacles as long as 330 days. The antifouling ability of hydrogels to barnac...

    Approximately 25% of children diagnosed with cancer eventually die. Losing a child puts parents at increased risk for developing psychological problems. To explore parents' perceptions of the interaction with health care professionals (communication, continuity of care, and parental involvement) and symptom management during the pediatric palliative phase, and to investigate the influence on long-term grief in parents who lost a child to cancer. A total of 89 parents of 57 children who died of cancer between 2000 and 2004 participated in this retrospective cross-sectional study by completing a set of questionnaires measuring grief (Inventory of Traumatic Grief), parents' perceptions of the interaction with health care professionals (communication, continuity of care, and parental involvement), and symptom management during the palliative phase. Care was assessed on a five point Likert scale (1=disagree and 5=agree). Parents highly rated communication (4.6±0.6), continuity of care (4.3±0.6), and parental involvement (4.6±0.7) during the palliative phase. Parents' most often reported physical and psychological symptoms of their child during the palliative phase were fatigue (75%), pain (74%), anxiety to be alone (52%), and anger (48%). Higher ratings of parents on communication (β=-9.08, P=0.03) and continuity of care (β=-11.74, P=0.01) were associated with lower levels of long-term parental grief. The severity of the child's dyspnea (β=2.96, P=0.05), anxiety to be alone (β=4.52, Pgrief. Multivariate models combining the interaction with health care professionals and symptom management showed a significant influence of both aspects on long-term parental grief. Both interaction with health care professionals, especially communication and continuity of care, and symptom management in children dying of cancer are associated with long-term parental grief levels.

    Prolonged visual deprivation from early childhood to maturity is believed to cause permanent visual impairment. However, there have been case reports of substantial improvement of binocular vision in human adults following lifelong visual impairment or deprivation. These observations, together with recent findings of adult ocular dominance plasticity in rodents, led us to re-examine whether adult primary visual cortex (V1) is capable of any recovery following long-term monocular deprivation s...

    Full Text Available Background: Takotsubo cardiomyopathy (TTC is characterized by reversible left ventricular dysfunction, frequently precipitated by a stressful event. Despite the favorable course and good long-term prognosis, a variety of complications may occur in the acute phase of the disease. The aim of this study was to evaluate the in-hospital and long-term outcomes of a cohort of TTC patients. Methods: Fifty-five patients (mean age 68.1±12 years were prospectively followed for a mean of 69.6±32.2 months (64,635 days. In-hospital (death, heart failure, arrhythmias and long-term events (death and recurrences were recorded. Results: Patients were predominantly women (87.3% who experienced a recent stressful event (emotional or physical and were admitted to hospital for chest pain. Eleven patients (20% had a diagnosis of depressive disorder, and arterial hypertension was the most frequent cardiovascular risk factor. The ECG revealed ST-segment elevation in 43.6% of patients. At angiography, seven cases (12.7% had at least one significant (≥50% coronary artery stenosis and four patients (7.3% had myocardial bridging of the left anterior descending artery. During hospitalization, three patients died (one from cardiac causes and cardiovascular complications occurred in 12 patients. During follow-up, five patients died (none from cardiac causes, six patients had recurrences within the first year. Two patients had two recurrences: one after 114 days, triggered by an asthma attack as the first event, and the other after 1,850 days. Conclusions: In TTC patients, in-hospital and long-term mortality is primarily due to non-cardiovascular causes. Recurrences are not infrequent and coronary artery disease is not an uncommon finding.

    (1) to generate in-depth insights into how nurses are working with older people with multiple long term conditions; (2) to gain an understanding of how nurses perceive professional patient navigation; and (3) to explore the barriers and facilitators to nurses adopting a navigation role in the context of Primary Health Care practice. Internationally, Primary Health Care has been identified as the main navigation point for older people with multiple long term conditions. Navigation models have been developed in cancer care but there is a lack of research in the context of Primary Care. There is also little evidence about the extent to which current work patterns of nurses providing care for this patient group fit with professional patient navigation models. A descriptive exploratory qualitative study. Semi-structured audio recorded telephone interviews were conducted in 2012 with nurses in New Zealand who were working with older people with multiple long term conditions (n = 42) Interviews were transcribed verbatim and entered into Nvivo 9 for thematic analysis. The key themes represent patterns of nursing work as; system work, relationship work and patient work. While nurses lacked a coherent understanding of patient navigation as a concept, the way they worked had some elements in common with professional navigation models. Further research involving older people in co-designing patient navigation approaches in Primary Health Care is needed to inform these types of service development and translate action from existing health policy. © 2014 John Wiley & Sons Ltd.

    A field experiment comparing different arable crop rotations was conducted in Denmark during 1997–2008 on three sites varying in climatic conditions and soil types, i.e. coarse sand (Jyndevand), loamy sand (Foulum), and sandy loam (Flakkebjerg). The crop rotations followed organic farm management......, and from 2005 also conventional management was included for comparison. Three experimental factors were included in the experiment in a factorial design: 1) crop rotation (organic crop rotations varying in use of whole-year green manure (O1 and O2 with a whole-year green manure, and O4 without...... manure there was a tendency for increased DM yield over time at all sites, whereas little response was seen in N yield. In the O4 rotation DM and N yields tended to increase at Foulum over time, but there was little change at Flakkebjerg. The DM yield gap between organic and conventional systems in the 3...

    Ocean acidification may affect zooplankton directly by decreasing in pH, as well as indirectly via trophic pathways, where changes in carbon availability or pH effects on primary producers may cascade up the food web thereby altering ecosystem functioning and community composition. Here, we present results from a mesocosm experiment carried out during 113 days in the Gullmar Fjord, Skagerrak coast of Sweden, studying plankton responses to predicted end-of-century pCO2 levels. We did not observe any pCO2 effect on the diversity of the mesozooplankton community, but a positive pCO2 effect on the total mesozooplankton abundance. Furthermore, we observed species-specific sensitivities to pCO2 in the two major groups in this experiment, copepods and hydromedusae. Also stage-specific pCO2 sensitivities were detected in copepods, with copepodites being the most responsive stage. Focusing on the most abundant species, Pseudocalanus acuspes, we observed that copepodites were significantly more abundant in the high-pCO2 treatment during most of the experiment, probably fuelled by phytoplankton community responses to high-pCO2 conditions. Physiological and reproductive output was analysed on P. acuspes females through two additional laboratory experiments, showing no pCO2 effect on females’ condition nor on egg hatching. Overall, our results suggest that the Gullmar Fjord mesozooplankton community structure is not expected to change much under realistic end-of-century OA scenarios as used here. However, the positive pCO2 effect detected on mesozooplankton abundance could potentially affect biomass transfer to higher trophic levels in the future. PMID:28410436

    Full Text Available Purpose: To estimate the value of LINAC-based stereotactic radiosurgery (SRS for the long-term local control of unilateral acoustic neuromas. Materials and Methods: Twenty patients (median age 66; range 57-80 years with unilateral acoustic neuroma underwent LINAC-based SRS from May 2000 through June 2004 with a dose of 11-12 Gy. The follow-up period ranged from 36 to 84 months (median follow-up period: 55 months. Before SRS none of the patients had useful hearing. The follow-up consisted of repeat imaging studies and clinical examination for assessment of facial and trigeminal nerve function at 6-month intervals for the first year and yearly thereafter. Results: Eleven tumors (58% decreased in size and eight (42% remained stable. One tumor showed a minor increase in size on the MRI done 6 months after SRS in comparison with the pretreatment MRI; however, a subsequent decrease was noticed on the next radiographic assessment and the tumor remained stable from then on. None of the tumors increased in size in the long-term follow-up, thus giving an overall growth control of 100% for the patients in this study. None of the patients had useful hearing before SRS, so hearing level was not assessed during follow-up. No patient developed new, permanent facial or trigeminal neuropathy. Conclusion: LINAC-based SRS with 11-12 Gy provides excellent tumor control in acoustic neuroma and has low toxicity even after long-term follow-up.

    The connection between stress and disease has been part of folk wisdom for a long time and has even made its way into our language with phrases such as 'scared to death' and 'a broken heart'. Takotsubo syndrome is a form of acute, reversible heart failure characterized by ballooning of the left ventricle. Post-menopausal women are primarily affected, but cases have been described in both sexes and at all ages. The complete pathophysiology is unknown, but the disease has been connected to psychological or physical stress and a surge in catecholamines. Despite the strong connection with stress, knowledge about the life of patients before the onset of Takotsubo syndrome is lacking. The aim of this study was to describe and interpret patients' narratives about long-term stress experienced before the onset of Takotsubo syndrome. Nineteen people diagnosed with Takotsubo syndrome were interviewed. The narrative interviews were recorded and transcribed verbatim. The resulting texts were analysed using phenomenological hermeneutics. The analysis revealed that the interviewees lived under stressful circumstances, characterized by feeling burdened by responsibilities, injustice and uncertainty, long before the onset of Takotsubo syndrome. This long-term stress wore down the defences of the interviewees to the degree that their capacity was exhausted and the smallest stressor could 'tip them over the edge'. The findings indicated that the social structure of gender possibly contributed to the interviewees' condition. These findings indicated that long-term stressful circumstances may cause vulnerability to acute psychological or physical stressors and, subsequently, to the onset of Takotsubo syndrome. © The European Society of Cardiology 2015.
